However, the tree rows in agroforestry systems, particularly in alley cropping systems (ACS), can affect crop productivity on adjacent agricultural fields through various mechanisms. Hence, concerns about declining yields and reduced farm profitability persist and explain the reluctance of farmers to implement ACS on their land. In this review, we examine the available literature on the effects of temperate ACS on yields of various agricultural crops to evaluate if and to what extent crop yields in ACS are affected by tree presence. We identified that ACS crop yields often vary substantially across different species, geographical locations, weather conditions and ACS designs. Our analysis also revealed that several parameters are modified in ACS by the presence of tree rows affecting crop yields positively or negatively and that ACS design aspects play a crucial role in determining crop productivity.

One possible source of renewable energy in parts of Europe is the use of crop for bioenergy production. Currently, maize dominates the biogas production. For a diversified production of substrates alternative crops needs to be evaluated for their sustainable utilization and ecological integration into agro-systems. The new bioenergy plants IGNISCUM Candy and IGNISCUM Basic are cultivars of the Sakhalin Knotweed (Fallopia sachalinensis, Fam. Polygonaceae), which are characterized by a high annual biomass production. Information on the crop production of this species is rare. Hence, understanding plant response to the combinations of water and nutrients availability is crucial for the development of sustainable plant production. In greenhouse experiments we investigate the interrelations between nutrient supply, biomass production, and plant ecophysiology. For the determination of yield-transpiration relations at whole plant level we used a wick lysimeter system, which allows us to study plant growth under controlled water regimes and to calculate the plant transpiration. The irrigation is supplied by an automatic drip irrigation system and computer-controlled in relation to the volumetric soil water content. Four different water treatments associated to the SWC range from well-watered to drought stressed plants. The influence of plant sizes on plant water use was investigated under different nitrogen supply. The fertilizer applied is calcium ammonium nitrate (N) and the rates for the four treatments are 0, 50, 100, 150 kg N/ha at the beginning of the growing season. Plant transpiration is calculated on the basis of water input, storage and drainage in weekly intervals. The cumulative transpiration of the plants during the growing season is between 49 L (drought stressed) and 141 L (well-watered) per plant, respectively. We calculated a transpiration coefficient of 525 Liters per kg dry biomass.

T1 - Soil respiration in alley-cropping system composed of black locust and poplar trees, Germany T2 - 2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany N2 - Understanding of soil carbon dynamics after establishment of alley-cropping systems is crucial for mitigation of greenhouse gas CO2. This study investigates soil CO2 flux in an alley-cropping system composed of black locust (Robinia pseudoacacia L.) and poplar (Max 1) tree strips and adjacent to them crop strips (Lupinus/ Solarigol). Soil CO2 flux was measured monthly over the March – November 2012 period, using a LI-COR LI-8100A automated device. Simultaneously with CO2 flux measurements, soil and air temperature, soil moisture, microbial C and hot water-extractable carbon (HWC) were determined for soils collected nearby each measurement collar. Root biomass was measured to a depth of 15 cm. In all sampling areas, soil CO2 flux increased from May to July, showing a significant positive correlation with air and soil temperature, which can be a reflection of increase in photosynthetic activity over the warm summer months. The relationships between soil moisture and CO2 flux showed positive correlation only for the warm period (May - October), indicating enhancing role of soil moisture on microbial mineralization and root respiration. CO2 flux values varied between sampling areas at different vegetation periods, with significantly higher values in trees over the summer. This could be attributed to the higher photosynthetic activity and higher root density in trees coppices compared to crops. In autumn, after seeding catch crop mix Solarigol, CO2 flux was significantly higher in crops compared to trees, which could be related to soil tillage prior to seeding of crops, as well as to the higher photosynthetic activity of newly seeded crops at the period of rapid plant growth. Despite a seasonal variation in CO2 flux between sampling areas, aaverage CO2 flux values observed over March – November period did not differ significantly between sampling areas, showing 2.5, 3.2, and 2.9 μmol m-2 s-1 values for black locust, poplar and crops, respectively. A greater C loss with soil respiration under trees in summer period may be compensated by greater C assimilation and storage in woody biomass, and the greater respiration from crop strips after tillage in autumn.

N. T1 - Alley Cropping - A promising multifunctional form of land use for reclaimed lignite mining sites in Germany T2 - 2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany N2 - Since the 1920s, more than 80.000 ha of land have been affected by lignite opencast mining activities in the Lusatia region (Eastern Germany), resulting in the evolution of large post-mining landscapes with substrates poor in humus and nutrients. As a consequence, the current conventional crop production on these post-mining areas is restricted. Against this background, the increasing demand for woody biomass for bioenergy, and thus the cultivation of fast growing trees for woody biomass production, could represent a promising option to enhance the productivity of land reclaimed from mining. Accordingly, considerable research has been carried out over the last two decades on reclamation technology, in addition to attempts to improve the soil quality through the use of different fast growing tree species in the Lusatia lignite region. Through such studies, it has been shown that it is possible to cultivate a sustainable supply of bioenergy wood through the use of black locust (Robinia pseudoacacia L.) trees, even under the unfavourable growth conditions of the marginal post mining areas. Since this knowledge is mainly based on studies of monocultural plantations (SRC), in 2007 a short rotation alley cropping system (SRACS) was established in the reclaimed lignite mining site “Welzow-Süd” with the purpose of obtaining fresh insight. The present paper evaluates the positive impacts of agroforestry land-use in terms of soil fertility, agricultural crop production, and soil protection against wind erosion based on the results of several years of examination made in this degraded area.

N. T1 - Impact of black locust hedgerows on wind velocity and wind erosion in Eastern Germany T2 - 2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany N2 - The production of energy wood on arable land increased in Germany during the last years. Black locust (Robinia pseudoacacia L.) is a suitable tree species in order to ensure substantial woody biomass yields on agricultural sites in eastern Germany. Arranged in hedge structures (alley cropping) positive effects on wind velocity and hence on soil erosion can be expected for the whole agricultural production area. Results of field measurements carried out in several alley cropping sites located in eastern Germany show that wind velocity can be reduced by more than 50 %, even though tree hedgerows were not higher than four meters. Here, the reduction of wind speed was dependent on the distance to woody crops, the width of the crop alleys and the orientation of hedgerows. As a result of wind speeds reduction the potential of soil erosion by wind decreases considerably. The risk of wind erosion is even nearly negligible for 24 m wide or smaller crop alleys. The establishment of short rotation hedgerows could contribute to an enhanced protection against wind erosion and thus to an ecological and possible long-term economic appreciation of agricultural sites. Aside from erosion control, further advantages such as a lower evaporation rate, and thus a crop yield increase, may be connected to the establishment of such agroforestry systems. Against the background of the increasing demand for woody biomass for bioenergy, the cultivation of fast growing trees on agricultural sites can furthermore result in an additional incomefor farmers. This is a prerequisite for the spread of this kind of agroforestry in Germany, because a comparable large share of an unprotected field has to be planted with trees in order to ensure an efficient windbreak.

However, concerns about yield reductions persist and whether these are driven by microclimate alterations or below-ground competition for water remains unclear. In this study, we measured wind speed, air temperature, and global radiation at seven positions within a 48 m wide crop alley of a short rotation ACS in Germany with summer barley (Hordeum vulgare) and poplar (Populus nigra × P. maximowiczii and P. trichocarpa Torrey & A. Gray) and on a treeless reference field (OF) during a particularly dry and warm year. Additionally, gravimetric soil water content and crop yield were assessed with high spatial resolution. Our results show that tree strips influenced all measured parameters. Global radiation and air temperature patterns varied dynamically with shading, while night-time air temperatures were unexpectedly highest on the OF. Wind speeds were reduced by up to 98% near tree strips and 81% further away. Soil water content displayed a U-shaped pattern, with higher values near tree strips, a rare observation in ACS. Crop yields in the ACS were twice as high as in the OF, despite being lower near tree strips. Yields were strongly correlated with global radiation but not with air temperature, wind speed, or soil water content. These findings provide preliminary evidence that tree presence in ACS can, under certain conditions, contribute to increased crop yields. The results suggest that ACS provide potential benefits for sustainable land-use, but further multi-year and multi-site studies are needed to validate the observed yield patterns across different environments and years, particularly under varying climatic conditions. Further research should also explore the indirect effects of microclimate modifications on soil water dynamics, including evapotranspiration.

This work proposes a novel hardware-based approach to improve the performance of fixed-point simulation through a widthconfigurable architecture implemented on Field-Programmable Gate Arrays (FPGAs). To our knowledge, this is the first reported hardware-based solution for fixed-point simulation reported in the literature, which provides substantial speedup compared to traditional software-based approaches. The presented approach utilizes High-Level Synthesis (HLS) tools to create modular, reusable components that enhance the design reusability. This approach accelerates fixed-point simulation for various applications, requiring only minor modifications to the application code to utilize it. By incorporating simulation capabilities within reusable functions, this work improves the efficiency and adaptability of the fixed-point simulation process. Implementation results for two FIR filter applications show that the proposed methodology is superior to traditional software-based approaches in reducing simulation time by two orders of magnitude and thus has the potential to improve the productivity of the DSP system design flow.

The experimental setup utilized a COHERENT HighLight FL8000-ARM fiber laser with concentric intensity distribution created by an optical fiber cable. The European Synchrotron Radiation Facility (ESRF, beamline ID19) was used to conduct high-speed synchrotron imaging at 20,000 images per second to study the spatio-temporal keyhole behavior. Keyhole geometries were extracted through advanced image processing techniques, allowing quantification of parameters like depth, aperture, bulging, and determination of related oscillation frequencies. The results showed that core-dominated processes exhibit significant variations in keyhole geometry. In contrast, ring-dominated processes exhibited reduced penetration depths but increased melt pool dynamics due to altered absorption conditions and increased temperatures within the melt pool. A stabilized core-ring power distribution minimized fluctuations, resulting in improved process stability. The findings were summarized in a model concept describing three characteristic keyhole regimes: core-dominated, ring-dominated, and stabilized core-ring processes.

Studies have reported a gap between research findings and clinical practice in physiotherapy. Guideline adherence is often used as a measure of agreement between therapeutic care and guideline recommendations. However, there is currently no standardised methodological approach for measuring guideline adherence.Aims and ObjectiveThe objective of this scoping review was to summarise the methods and results of studies that assessed guideline adherence in physiotherapy.MethodsMEDLINE, EMBASE, PEDro and CENTRAL databases were searched for relevant literature up to December 2022. Published reports of observational studies and controlled clinical trials that provided information on the assessment of guideline adherence in physiotherapists were included. The selection process was performed independently by two reviewers. The methodological quality of the identified reports was not assessed. Results were summarised narratively.ResultsFrom a total of 2560 potentially relevant records, 53 reports were included in the analysis. Physiotherapists' adherence to guidelines was primarily assessed in the context of musculoskeletal conditions, such as low back pain (n = 25, 47.2%) and osteoarthritis (n = 8, 15.1%). A wide range of measurement approaches were used with the majority of reports using web‐based surveys (n = 21, 39.6%), followed by chart reviews (n = 17, 32.1%). Most reports (n = 21, 39.6%) provided information on the level of adherence in terms of frequency dichotomising (self‐reported) clinical practice as adherent or non‐adherent. Adherence rates varied widely between included reports.ConclusionsAlthough the large number of included reports indicates a high level of interest in the topic of guideline adherence, there is considerable heterogeneity between studies regarding the methodological approaches used to assess guideline adherence in physiotherapists. This reduces the comparability of the study results.Trial RegistrationINPLASY (registration no. 202250081). Registered on 12th May 2022.

Zur Linderung von Beschwerden und zum Erhalt der Gelenkfunktion wird in Leitlinien vor allem Edukation und Bewegungstherapie empfohlen. Mobile Gesundheits-Apps mit integrierten Heimübungsprogrammen können eine sinnvolle Ergänzung zur physiotherapeutischen Behandlung darstellen. Unklar ist jedoch, inwieweit solche Anwendungen tatsächlich zum Krankheitsmanagement verwendet werden. Ziel Untersuchung der Nutzung mobiler Gesundheits-Apps durch Personen mit Hüft- und Kniegelenksarthrose in Deutschland. Methode Von Juli bis August 2024 wurde eine deutschlandweite Online-Befragung unter Personen mit Hüft- und Kniegelenksarthrose durchgeführt. Erhoben wurden u. a. der Bekanntheitsgrad und die Nutzung allgemeiner sowie arthrosespezifischer Gesundheits-Apps, Gründe gegen die Nutzung und weitere Einflussfaktoren. Die Daten wurden deskriptiv mithilfe von Microsoft Excel ausgewertet. Ergebnisse Von insgesamt 88 Teilnehmenden konnten die Antworten von 68 in die Auswertung einbezogen werden. Das Durchschnittsalter der Teilnehmenden lag bei 65,8 (± 8,7) Jahren, 85,3 Prozent (58/68) waren weiblich. Dem Großteil der Befragten (58/68, 85,3 %) waren mobile Gesundheits-Apps grundsätzlich bekannt, 41,2 Prozent (28/68) hatten bereits eine solche App genutzt. Apps, die speziell für Personen mit Arthrose entwickelt wurden, waren weniger bekannt (37/68, 54,4 %). Gleichzeitig zeigten sich 58,9 Prozent (40/68) offen für eine zukünftige Nutzung von mobilen Apps mit integrierten Übungsprogrammen, wenn diese von medizinischem Fachpersonal empfohlen würden. Als zentrale Hinderungsgründe für die Nutzung einer solchen Gesundheits-App nannten die Teilnehmenden eine fehlende persönliche Interaktion sowie Unsicherheiten bei der korrekten Übungsausführung. Schlussfolgerungen Obwohl unter den Teilnehmenden generelles Interesse an der Nutzung mobiler Gesundheits-Apps besteht, ist die aktuelle Zahl der Nutzer*innen gering. Um das Potenzial solcher Anwendungen bei der Behandlung von Personen mit Arthrose besser auszuschöpfen, sollten Aufklärung und gezielte Empfehlungen durch Ärzt*innen und Physiotherapeut*innen verstärkt werden. Mobile Gesundheits-Apps könnten so zur Unterstützung von Bewegungstherapie und zur Förderung der Eigenverantwortung der Patient*innen beitragen. N2 - Background Osteoarthritis is the most common degenerative joint disease worldwide and is also highly prevalent in Germany. Education and exercise therapy are recommended as first-line treatments in clinical practice guidelines to reduce pain and improve physical function. Physiotherapy can be complemented by mobile health apps that provide home exercise programs. However, it is unclear to what extent such applications are used for disease management. Aim To investigate the use of mobile health apps among individuals with hip and knee osteoarthritis in Germany. Method In a nationwide web-based survey conducted between July and August 2024, individuals with hip and knee osteoarthritis were asked about awareness and use of mobile health apps, particularly those specific for osteoarthritis, as well as potential reasons for non-use and other influencing factors. The data were analyzed descriptively using Microsoft Excel. Results A total of 88 individuals participated in the survey, of whom 68 were included in the analysis. The mean age of participants was 65.8 (± 8,7) years, and 85.3 % (58/68) were female. Most respondents (58/68, 85.3 %) were familiar with mobile health apps, and 41.2 % (28/68) had previously used at least one. Apps specifically developed for persons with osteoarthritis were less well known (31/68, 45.6 %). Nevertheless, 58,9 % (40/68) of respondents expressed interest to use exercise-based apps in the future, if recommended by healthcare professionals. The main barriers to mobile health app use were lack of personal contact and uncertainty about how to perform the exercises correctly. Conclusions Although there was a widespread interest among participants in using mobile health apps for osteoarthritis management, actual usage remained low. In order to integrate such applications more effectively into osteoarthritis management, healthcare professionals, in particular physicians and physiotherapists, should provide targeted education and recommendations. The use of mobile health apps can complement exercise therapy and encourage patients to take a more active role in managing their condition.

This paper cross-validates experimental and numerical results, focusing on the scaling of turbulence statistics at the pipe centerline and across the inner-outer flow region. Pipe flow experiments were reviewed for friction Reynolds numbers 810≤Re𝜏≤55×103, where Re𝜏=𝑢𝜏⁢𝑅/𝜈, 𝑢𝜏 is the wall friction velocity, 𝑅 the pipe radius, and 𝜈 the kinematic viscosity. Complementary DNS data for 180≤Re𝜏≤2880 provide detailed insight into near-wall turbulence. A novel friction correlation, Re𝜏=0.048Re0.923 c is introduced, predicting pipe-wall friction across a wide range of Re𝑐 with accuracy better than ±2.06%, where Re𝑐 is the Reynolds number based on the centerline streamwise mean velocity component 𝑈zc. This correlation enables reliable friction estimates from centerline single-point measurements or DNS data without requiring near-wall or streamwise pressure-gradient information and is validated by consistent agreement with both experiments and DNS. The monotonic decrease in centerline turbulence intensity ⟨𝑢′𝑧2⟩1/2/𝑈zc with increasing Re𝑐 is explained using the streamwise mean momentum equation. Finally, azimuthal spatial filtering of DNS data highlights the limitations of hot-wire resolution near the wall. For Re𝜏≥2880, higher-order experimental statistics agree well with DNS for 𝑦+≥30 and into the logarithmic region, with both datasets equally well described by logarithmic or power-law correlations, while near-wall discrepancies remain due to resolution limits.

Although it is already known that blade balancing affects aerodynamic properties, this correlation is often not taken into account, which is why it is usually performed as an independent step after solving the aerodynamic design problem. However, this assumption is questionable because such shifts should be used to control both secondary flow effects and resulting stress. Therefore, the paper proposes problem formulations combining both aspects. Since optimisation requires costly numerical evaluations, machine learning methods are investigated to predict aerodynamic performance and stress constraints more efficiently. This enables a global optimisation process by reducing computational costs. Various different surrogate types are investigated, where stress constraints are formulated either as regression task predicting stress maxima, or as classification problem directly assessing design feasibility.

This includes the first structurally characterized Np complex with (N,S)-donor ligands, filling a notable gap in An coordination chemistry. An improved synthetic approach with PyS–SiMe3 enabled efficient formation of the 1:4 complexes in THF as coordinating solvent. The compounds were comprehensively characterized in solution and in solid phase, supported by quantum chemical calculations. Experimental and theoretical results show matching trends in the binding behavior of AnIV. The covalent bond contributions in An–N and An–S bonding increase along the series of An from Th to Pu. The bonds to the soft sulfur donors consistently have the highest covalent contributions with a remarkably high percentage for Pu–S (IQA analysis: >34%) over the harder N donors or An–O bonds of coordinating THF. High-resolution X-ray absorption and infrared spectroscopy indicate similar electronic and structural properties across AnIV complexes, while SQUID magnetometry uncovered significant differences in magnetic behavior at low temperatures depending on the complex compositions. This work advances the understanding of An-ligand bonding, emphasizing covalency and electronic structures, and expands fundamental insights into An chemistry.

Nov. (formerly MBA03), a potential key player in anaerobic digestionstion T2 - Microbial biotechnology N2 - Biogas, a mix of CO2, CH4 and small proportions of other gases, is a biofuel obtained by anaerobic digestion (AD). Biogas production is often considered a black box process, as the role and dynamics of some of the microorganisms involved remain undisclosed. Previous metataxonomic studies in the frame of the MICRO4BIOGAS project (www. micro 4biog as. eu) revealed that MBA03, an uncharacterised and uncultured bacterial taxon belonging to phylum Bacillota, was very prevalent and abundant in industrial full-scale AD plants. Despite the efforts, this taxon has not yet been cultivated, which makes the analysis of its taxonomy, ecology and metabolism even more challenging. In the present work, 30 samples derived from anaerobic digesters were sequenced, allowing the reconstruction of 108 metagenome-assembled genomes (MAGs) potentially belonging to MBA03. According to phylogenetic analyses and genomic similarity indices, MBA03 was classified as a new bacterial order, proposed as ‘Candidatus Darwinibacteriales’ ord. nov., which includes ‘Candidatus Darwinibacter acetoxidans’ gen. nov., sp. nov. of ‘Candidatus Darwinibacteriaceae’ fam. nov., along with ‘Candidatus Wallacebacter cryptica’ gen. nov., sp. nov. of the ‘Candidatus Wallacebacteriaceae’ fam. nov. Ecotaxonomic studies determined that AD processes are the main ecological niche of ‘Candidatus Darwinibacteriales’. Moreover, metabolic predictions identified Darwinibacteraceae members as putative syntrophic acetate-oxidising bacteria (SAOB), as they encode for the reversed Wood–Ljungdahl (W–L) pathway coupled to the glycine cleavage system. This suggests that Darwinibacteraceae members could work in collaboration with hydrogenotrophic methanogenic archaea to produce methane in industrial biogas plants. Overall, our findings present ‘Candidatus Darwinibacteriales’ as a potential key player in anaerobic digestion and pave the way towards the complete characterisation of this newly described bacterial taxon, which has not yet been cultured.

Structural, compositional, and morphological properties were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX). Gas sensing measurements showed effective hydrogen detection at room temperature, with the sensitivity strongly influenced by Sn content and oxygen vacancy concentration. Higher Sn concentration enhanced the sensing response, which was correlated with microstructural features obtained from AFM and EDX, as well as with the presence of Ce3+ and Ce4+ oxidation states identified by XPS. This study highlights the potential of CeOx/SnOx thin films for possible back-end-of-line integration and provides proof-of-principle for room-temperature hydrogen sensing.

It is widely employed in various applications, including digital communication, image processing, and signal analysis. Recently, in-memory computing architectures based on emerging technologies, such as resistive RAM (RRAM), have demonstrated promising performance with low hardware cost for data-intensive applications. However, directly mapping FFT onto RRAM crossbars is challenging because the algorithm relies on many small, sequential butterfly operations, while cross-bars are optimized for large-scale, highly parallel vector–matrix multiplications (VMMs). In this paper, we introduce ReFFT, a system architecture that reformulates FFT computations for efficient execution on RRAM crossbars. ReFFT combines the reduced computational complexity of FFT with the parallel VMM capability of RRAM. We incorporate measured device data into our framework to analyze the effect of variability and develop an adaptive mapping scheme that improves twiddle-factor programming accuracy, leading to a 9.9 dB peak signal-to-noise ratio (PSNR) improvement for a 256-point FFT. Compared with prior RRAM-based DFT designs, ReFFT achieves up to 4.6× and 19.5× higher energy efficiency for 256- and 2048-point FFTs, respectively. The system is further validated in digital communication and satellite image compression tasks.

The mean readout current and its standard deviation can be calculated for binary and multi-level devices. These values are important for simulating hardware-based artificial neural networks at circuit level and testing their functionality. Research into hardwarebased artificial neural networks is important because they are energy-efficient. Furthermore to calculating the variations, the statistical model can be used to determine what influence the cumulative distribution function of switching has on the variations and which behavior provides the best results for the hardwarebased artificial neural network. Some memristive devices exhibit multi-level behavior due to defects in the switching layer. The number of these defects and the optimal amount can be estimated.

However, due to the immature fabrication process and inherent material instabilities, frequent read operations during computations can induce read disturb effects, leading to unintended resistance drift and potential data corruption. Existing mitigation approaches primarily focus on detecting read disturb effects and triggering memory refresh operations. In this work, we propose an architecture-level solution that mitigates read disturb in RRAM-based accelerators. Our strategy employs crossbar duplication and decomposes the single high input pulse into two lower-amplitude pulses, effectively minimizing the risk of read disturb. To validate our approach, we develop a simulation framework that incorporates measurement data from characterized RRAM devices under read disturb stress conditions. Experimental results on VGG-8 with CIFAR-10 demonstrate that the proposed method significantly mitigates inference accuracy degradation caused by read disturb in RRAM-based accelerators, while incurring modest area and energy overheads of 12.32% and 2.15%, respectively. This work provides a practical and scalable solution for enhancing the robustness of RRAM-based accelerators in edge and high-performance computing applications.

Therefore, the electron reflectivity, the Sherman function, and the figure of merit are measured for the following samples: a single layer of MoS₂ on Au(111) and cleaved MoS₂ single-crystal surfaces. MoS₂ offers promising features for the use in spin-polarization detection: working points with a reversed sign of the Sherman function and a long-term target stability. To overcome the low figure of merit of MoS₂, the closely-related 2D material WS₂ with higher spin-orbit interaction is proposed, which may resemble the promising features with higher Sherman function. This study demonstrates the potential suitability of 2D materials such as TMDCs as scattering targets in spin-polarization detectors.

A1 - Bunn, Christian A1 - Ryo, Masahiro T1 - Smartphone‐based monitoring identifies the importance of farm size and soil type for coffee tree productivity at a large geographic scale T2 - Journal of sustainable agriculture and environment N2 - Smartphone‐based monitoring has been increasingly applied to coffee crops for multiple tasks, such as predicting coffee tree productivity. However, its implementation remains limited to small‐scale use, typically at the individual plant level. At larger scales, such as the farm level, its application is largely unexplored. Moreover, it is unclear whether the use of smartphone‐based monitoring can help identifying key factors driving coffee tree productivity such as climate, soil, and management characteristics. To address these challenges, we investigate coffee tree productivity at the farm level and its key driving factors using smartphone‐based monitoring and explainable artificial intelligence (xAI), and compare the results with those obtained from manual monitoring at the farm level. We used a multimodal data set composed of satellite data (soil and climate), smartphone‐based monitoring (coffee tree productivity), and management characteristics (area, shade trees, and farm shape). The results showed that smartphone‐based monitoring reached a of R ² = 0.84 in predicting coffee tree productivity at the farm level. The xAI results revealed that both smartphone‐based and manual monitoring approaches identified the coffee cultivation area (greater than 13 ha) and soil texture (sandy, clay loam) as the most important variables influencing coffee tree productivity at farm level. The analysis also indicated that shade trees do not significantly affect coffee tree productivity. These findings suggest that smartphone‐based monitoring can serve as a reliable and scalable alternative to manual monitoring for evaluating coffee tree productivity at the farm level.

The study utilizes the MNIST dataset to evaluate various Multi-Layer Perceptron configurations: a baseline model with a Single-Layer Perceptron and an extended model with multiple hidden nodes. The effects of Cycle-to-Cycle variability on network accuracy are explored by varying parameters such as the standard deviation to simulate dynamic changes in network weights. In particular, the performance differences between the Single-Layer Perceptron and the Multi-Layer Perceptron with hidden layers are analyzed, highlighting the network’s robustness to stochastic perturbations. These results provide insights into the effects of quantization and network architecture on accuracy under varying levels of variability.

Intrinsic RS values were extracted from I-V characteristics measured over 50 Reset-Set cycles at various gate voltages (VG) by using a numerical transformation method. Results reveal the contribution of the transistor’s resistance to the overall RS. A linear relationship between RS values and Set transition voltages (VTS) was found, with larger RS values amplifying the variability in switching parameters. Comparative analysis of cumulative distribution functions (CDFs) highlights differences between technologies, showing lower VTS values as well as lower sensitivity to RS for Al:HfO₂-based devices. These findings underscore the critical role of RS in modeling and optimizing the performance of RRAM devices for reliable operation.

The characteristic feature of the problem under consideration is the Tikhonov regularization term in form of the transportation distance of the control to a given prior. Existence of optimal solutions is shown and first-order necessary optimality conditions are derived. The latter are used to deduce structural a priori information about the optimal control and its support based on properties of the associated optimal transport plan.

Variable-rate technology (VRT) enables the application of the right amount of resources at the right time and place to meet crop requirements. VRT remains relatively underutilized in European arable farming compared to Americas and Australia. Facilitating VRT adoption and other precision agricultural technologies in European arable farming requires understanding the pressing needs of farmers and proposing location-specific solutions to their problems. To address this gap, we conducted online surveys of experts in agricultural research, service, and primary production across seven European arable farming regions. Experts were asked to estimate the current and future adoption of VRT and to assess the role of relevant factors for adopting VRT in their regions. Furthermore, we asked about the challenges of fertilization, weed/pest control, and water management. Our results show a higher current and future VRT application for fertilization compared to weed/pest control and irrigation across all regions. The biggest barriers against VRT adoption in arable farming are cost, government regulations, and technology complexity. Moreover, our results show that VRT can more efficiently address the challenges of fertilizer application and weed/pest control, but has limited potential in addressing water management challenges, which need to be tackled by crop breeding, irrigation infrastructure, and water withdrawal rights. Our findings suggest that the low adoption of VRT in Europe is related to high cost and complexity of VRT, the substitute measures of VRT, and the limitation of VRT in addressing agroecological and policy-related challenges. Sustainable intensification thus requires a portfolio of technological, social, behavioral, and policy innovations.

We lack knowledge about how current agricultural contexts may influence future development pathways and the relative importance of the two approaches. This study explores the alignment between past uptake of agroecological and technological practices and future visions of agricultural development in seven European arable farming systems. By combining landscape mapping with farmer interviews, we first assessed the past adoption of agroecological and technological practices in each region. Then, we compared our findings with expert surveys about the future directions of agricultural development that can address local arable farming challenges. We found that in regions with intensive arable farming, agroecological approaches lagged behind the uptake of technological measures, both in the past and in future prospects. In low-intensity regions, we found large gaps between past uptake and future prospects of agroecological and technological practice adoption. These gaps need to be overcome in the context of future challenges of climate change adaptation and of environmental obligations. Our results indicate the need to take differentiated measures depending on farm management intensity and landscape conditions to enhance the future uptake of agroecological and technological solutions that can address the local challenges.

Its activity could be determined by non-invasive and cost-effective assays, such as breath analysis, for the personalised monitoring of drug response. For the first time, we identify an isotopically unlabelled CYP3A4 substrate, tolterodine that leads to the formation of a non-toxic volatile metabolite, acetone, which could potentially be applied to monitor CYP3A4 activity in humans. In vitro biotransformation of tolterodine by HepG2 cells overexpressing CYP3A4, CYP2D6 or CYP2C9 was investigated by LC-MS analysis of cell culture supernatant for the non-volatile metabolite, N-dealkylated tolterodine, and PTR-ToF-MS analysis of the headspace for acetone. The highest level of the N-dealkylated metabolite was produced by HepG2-CYP3A4. Concentration dependent effects of tolterodine were analysed, resulting in TC50 values of 414 µM and 375 µM for HepG2-CYP3A4 and reference cells, respectively. Acetone and N-dealkylated tolterodine levels increased continuously over 24 h in HepG2-CYP3A4. Treatment with either a pan-CYP inhibitor, 1-aminobenzotriazole, or a CYP3A4 inhibitor, ketoconazole, considerably reduced the production of both metabolites in HepG2-CYP3A4 cells. These findings pave the way for the further development of non-invasive breath tests using unlabelled precursors to determine CYP enzyme activity in individuals.

In diesem Spannungsfeld bieten digitale Innovationen die Chance, Effizienz und Versorgungsqualität zu verbessern. Insbesondere Virtual Reality (VR) eröffnet durch ihre immersiven Eigenschaften neue Möglichkeiten in Diagnostik, Therapie und Ausbildung. VR ermöglicht sowohl realitätsnahe Trainingsszenarien für medizinisches Personal als auch interaktive Anwendungen zur Schmerzreduktion und psychischen Stabilisierung von Patien*innen. Trotz vielversprechender Ergebnisse ist der Einsatz in der Praxis bislang begrenzt, was auf technische, organisatorische und rechtliche Hürden zurückzuführen ist. Implementierungsstudien zeigen jedoch, dass sich Barrieren durch gezielte Strategien reduzieren und die Akzeptanz fördern lassen. Zukünftige Entwicklungen, insbesondere durch Künstliche Intelligenz und verbesserte Hardware, könnten VR zu einem integralen Bestandteil der Gesundheitsversorgung machen – vorausgesetzt, wissenschaftliche Evaluation, Datenschutz und Finanzierung werden nachhaltig sichergestellt.

Dennoch ist der Campus räumlich wie funktional vom Stadtkern getrennt. Neben physischen Barrieren erschweren auch mentale Hemmschwellen und eine geringe Nutzungsvielfalt seine Integration in den öffentlichen Raum. Im Seminar „Beteiligungsprozesse in Stadt- und Regionalplanung“ untersuchten Studierende daher, wie räumliche, programmatische und soziale „Trittsteine“ geschaffen werden können, um den Campus stärker mit dem städtischen Alltag zu verknüpfen. Ausgangspunkt war eine Analyse informeller Beteiligungsverfahren, aus der ein „Katalog der Beteiligung“ als methodischer Werkzeugkasten hervorging. Darauf aufbauend realisierten die Studierenden zwei konkrete Formate: eine Zukunftswerkstatt mit über fünfzig Teilnehmenden sowie einen Stadtspaziergang, der den Campus als Teil des öffentlichen Raums erfahrbar machte. Die Ergebnisse wurden in einer Ausstellung präsentiert und in einem Manifest zusammengeführt, das konkrete Handlungsempfehlungen an die Stadt Cottbus und die BTU formuliert. Ziel ist es, den Campus als offenen, urbanen Freiraum für alle Stadtbewohner:innen zu verankern und die Trennung zwischen Universität und Stadt nachhaltig zu überwinden. N2 - The campus of BTU Cottbus-Senftenberg and the city of Cottbus are linked by a reciprocal and highly promising relationship: while the university continuously generates impulses for knowledge, innovation, and cultural diversity, Cottbus with its historically evolved social and spatial fabric offers an inspiring context for teaching, research, and urban life. Nevertheless, the campus remains spatially and functionally separated from the city center. In addition to physical barriers, mental thresholds and a limited diversity of uses further hinder its integration into the public realm. Within the seminar “Participation Processes in Urban and Regional Planning,” students therefore explored how spatial, programmatic, and social “stepping stones” could be created to better connect the campus with the everyday life of the city. The starting point was an analysis of informal participation processes, from which a “Catalogue of Participation” emerged as a methodological toolkit. Building on this foundation, the students implemented two concrete formats: a future workshop with more than fifty participants and a guided urban walk that rendered the campus tangible as part of the public realm. The results were presented in an exhibition and synthesized in a manifesto that formulates concrete recommendations for action to both the City of Cottbus and BTU. The overarching aim is to establish the campus as an open, urban space accessible to all residents and to gradually overcome the spatial and mental separation between university and city.
