description: Water is crucial for dairy cows, making up 55-70% of their body weight and 85% of milk [Be12]. Restricted access to water affects health, welfare, milk quality and quantity, so adequate water intake is essential. Dairy cows’ drinking behavior is influenced by trough design and cleanliness, making monitoring important but tedious [Bu22]. This study introduces a deep-learning approach to detect the drinking event and monitor the total duration of drinking. The approach is divided into cow detection, identification, drinking event detection and tracking the total duration of the cow’s drinking. Various You Only Look Once (YOLO) models were used for cow detection, ResNet-18 and ResNet-50 for identification, and Deep SORT with OCR for detecting and tracking the drinking event. Various YOLO versions and ResNet models were compared for performance. The approach achieved 98% precision in cow detection, 98% accuracy in identification, and 95% accuracy in detecting the duration of drinking, with a 97% F1 Score, ensuring reliable monitoring of dairy cows’ health through their drinking behavior.

description: In a prior paper (Kim et al. 2015) we considered the linear stability of magnetized jets that carry no net electric current and do not have current sheets. In this paper, in addition to physically well-motivated magnetic field structures, we also include the effects of jet shear. The jets we study have finite thermal pressure in addition to having realistic magnetic field structures and velocity shear. We find that shear has a strongly stabilizing effect on various modes of jet instability. Increasing shear stabilizes the fundamental pinch modes at long wavelengths and short wavelengths. Increasing shear also stabilizes the first reflection pinch modes at short wavelengths. Increasing shear has only a very modest stabilizing effect on the fundamental kink modes at long wavelengths; however, increasing shear does have a strong stabilizing effect on the fundamental kink modes at short wavelengths. The first reflection kink modes are strongly stabilized by increasing shear at shorter wavelengths. Overall, we find that the combined effect of magnetic field and shear stabilizes jets more than shear alone. In addition to the results from a formal linear stability analysis, we present a novel way of visualizing and understanding jet stability. This gives us a deeper understanding of the enhanced stability of sheared, magnetized jets. We also emphasize the value of our numerical approach in understanding the linear stability of jets with realistic structure.

title: New content of teaching via an interdisciplinary agile approach to tackle digital challenges in the field of indoor vertical farming

Subjects: subject: teaching

subject: indoor vertical farming

description: Content of teaching is often highly specialized for each course of studies, and students rarely have the possibility to learn more about related content which is outside of the subject area. Nevertheless, e.g. in indoor vertical farming, not only horticultural expertise is required to face the need for automated processes throughout the whole supply chain. We present here a unique approach to bring students from different courses of study together to develop digital solutions for these challenges in an agile environment. Agile in this context means letting students from different disciplines work together in a self-organized manner without hierarchies and based on the project management framework Scrum. In a first attempt, we let students with horticultural and bioinformatics backgrounds develop a digital tool that automates early detection of nitrogen deficiency for sunflowers grown in a greenhouse.

Perennial herbs or bush, to 2 m tall. Stems erect, terete or 4-angular, branched, pubescent or subglabrous, glabrescent. Leaves opposite; petiole usually 3–5 cm long, sometimes up to 6.5 cm, subglabrous; blade ovate, 5–15 × 2.5–8 cm, adaxially sparsely pubescent or subglabrous, abaxially pubescent along veins otherwise glabrous, base broadly cuneate, cuneate, or round, margin double serrate or double crenate, apex acuminate, lateral veins 4–6 pairs on each side of the midvein. Spikes 3–15 cm × 6–10 mm, terminal and axillary, continuous or interrupted, with more than two lateral spikes; peduncle 0.5–4 cm long; verticillasters many-flowered, flowers sessile. Bracts and bracteoles ovate, 2.5–6 mm long, margin ciliate. Calyx tubular-inflated or subtubular, 3–4.5 mm long, 5-veined, glabrous, or pubescent outside, or sparsely pubescent only along veins; teeth 5, equal, triangular, ca. 1/3 as long as calyx tube, sparely pubescent or glabrous inside, margin ciliate. Corolla white, pink, purplish-white, or purple, 3.5–5.5 mm long, exserted, 2-lipped, upper lip 3-lobed, lobes apex obtuse, pubescent outside, lower lip entire, glabrous, apex acute. Stamens 4, exserted portion of filaments nearly as long as corolla; filaments bearded at middle, bearded portion exserted; anthers 1-locular, cell apex dehiscent; stigma bifid, equal, lobes 0.9–1.2 mm long. Nutlets 4, 0.5–0.6 mm long, globose, slightly flat, dark brown, shiny.
 Infraspecific variation: — The hairs on leaves, bracts, bracteoles and calyx are variable within this species. Most populations in this species are pubescent or subglabrous on leaves, bracts and bracteoles as well as outer part of calyx. However, several populations of this species from southeastern and central Yunnan are villous on their leaves, bracts and bracteoles as well as the outer part of the calyx. Based on this observation, two subgroups are recognized as varieties, var. glaber and var. tsingpingensis.

description: To examine the factors which facilitate UK military personnel with post-traumatic stress disorder (PTSD) to engage in help-seeking behaviours. The study recruited active service personnel who were attending mental health services, employed a qualitative design, used semi-structured interview schedules to collect data, and explored these data using interpretative phenomenological analysis (IPA). Five themes emerged about how participants were able to access help; having to reach a crisis point before accepting the need for help, overcoming feelings of shame, the importance of having an internal locus of control, finding a psychological explanation for their symptoms and having strong social support. This study reported that for military personnel who accessed mental health services, there were a number of factors that supported them to do so. In particular, factors that combated internal stigma, such as being supported to develop an internal locus of control, appeared to be critical in supporting military personnel to engage in help-seeking behaviour.

description: We show that the Bethe-Salpeter equation for the scattering amplitude in the limit of zero incident energy can be transformed into a purely Euclidean form, as it is the case for the bound states. The decoupling between Euclidean and Minkowski amplitudes is only possible for zero energy scattering observables and allows determining the scattering length from the Euclidean Bethe-Salpeter amplitude. Such a possibility strongly simplifies the numerical solution of the Bethe-Salpeter equation and suggests an alternative way to compute the scattering length in Lattice Euclidean calculations without using the Luscher formalism. The derivations contained in this work were performed for scalar particles and one-boson exchange kernel. They can be generalized to the fermion case and more involved interactions.

description: We present and discuss a stochastic model describing the wear process of cylinder liners in a marine diesel engine. The model is based on a stochastic differential equation and Bayesian inference is illustrated. Corrosive action and measurement error, both quite negligible, are modeled with a Wiener process whereas a jump process is used to describe the contribution of soot particles to the wear process. The model can be used to forecast the wear process and, consequently, plan condition based maintenance activities. In the paper, we provide a critical illustration of the mathematical and computational aspects of the model. We propose a strategy that, implemented for simulated and real data, allows for stable parameter estimation and forecasts.

description: Recently, an interesting inflationary scenario, named Gauss-Bonnet inflation, is proposed by Kanti et al.~\cite{Kanti:2015pda,Kanti:2015dra}. In the model, there is no inflaton potential but the inflaton couples to the Guass-Bonnet term. In the case of quadratic coupling, they find inflation occurs with graceful exit. The scenario is attractive because of the natural set-up. However, we show there exists the gradient instability in the tensor perturbations in this inflationary model. We further prove the no-go theorem for the Gauss-Bonnet inflation without an inflaton potential.

description: El estudio realizado, presenta un análisis comparativo de riesgos en los proyectos de tipo residencial con el sistema FAV en la ciudad de Cartagena. Se utilizó como objeto de estudio dos proyectos en etapa de ejecución con el sistema antes mencionado. Este análisis de riesgos se basó en los principios del método descrito por el PMBOK®, regido por los lineamientos del PMI® (Instituto de administración de proyectos), en el cual se parte de una identificación de los riesgos y se continúa con dos análisis consecutivos a estos riesgos. El objetivo de esta investigación es realizar un análisis comparativo de los riesgos que se puedan presentar en proyectos de edificación de tipo residencial desarrollados con el sistema tradicional y el sistema FAV® en la ciudad de Cartagena con el que se planteen a partir de los resultados cuál de los sistemas estudiados es menos riesgoso Esta investigación aplicó la metodología escogida a los cuatro aspectos que considera más importantes dentro de un proyecto de construcción, (cronograma, alcance, presupuesto y calidad), haciendo énfasis en el presupuesto y el cronograma durante la simulación de Monte Carlo, que es el punto de partida para le realización del análisis cuantitativo a cada una de las muestras. Dicha simulación fue realizada empleando el software @RISK donde se aplicaron modelos y distribuciones de probabilidad para poder obtener los resultados finales. Las simulaciones se hicieron a cada uno de las muestras por separado. Una vez se cumplió con la metodología que sirvió para hacer el análisis el resultado más relevante es que la probabilidad en promedio de terminar las actividades planeadas y ejecutadas es de 5% es decir 3 día antes mientras que la probabilidad promedio de que se retrasan estas actividades es de 5,3% es decir 3 días después y aun si no se terminaran las actividades en los tiempos establecidos el proyecto seguiría siendo viable

description: Mechanisms of human color vision are characterized by two phenomenological aspects: the system is nonlinear and adaptive to changing environments. Conventional attempts to derive these features from statistics use separate arguments for each aspect. The few statistical approaches that do consider both phenomena simultaneously follow parametric formulations based on empirical models. Therefore, it may be argued that the behavior does not come directly from the color statistics but from the convenient functional form adopted. In addition, many times the whole statistical analysis is based on simplified databases that disregard relevant physical effects in the input signal, as for instance by assuming flat Lambertian surfaces. Here we address the simultaneous statistical explanation of (i) the nonlinear behavior of achromatic and chromatic mechanisms in a fixed adaptation state, and (ii) the change of such behavior. Both phenomena emerge directly from the samples through a single data-driven method: the Sequential Principal Curves Analysis (SPCA) with local metric. SPCA is a new manifold learning technique to derive a set of sensors adapted to the manifold using different optimality criteria. A new database of colorimetrically calibrated images of natural objects under these illuminants was collected. The results obtained by applying SPCA show that the psychophysical behavior on color discrimination thresholds, discount of the illuminant and corresponding pairs in asymmetric color matching, emerge directly from realistic data regularities assuming no a priori functional form. These results provide stronger evidence for the hypothesis of a statistically driven organization of color sensors. Moreover, the obtained results suggest that color perception at this low abstraction level may be guided by an error minimization strategy rather than by the information maximization principle.

description: Very recent work introduces an asymptotically fast subdivision algorithm, denoted ANewDsc, for isolating the real roots of a univariate real polynomial. The method combines Descartes' Rule of Signs to test intervals for the existence of roots, Newton iteration to speed up convergence against clusters of roots, and approximate computation to decrease the required precision. It achieves record bounds on the worst-case complexity for the considered problem, matching the complexity of Pan's method for computing all complex roots and improving upon the complexity of other subdivision methods by several magnitudes. In the article at hand, we report on an implementation of ANewDsc on top of the RS root isolator. RS is a highly efficient realization of the classical Descartes method and currently serves as the default real root solver in Maple. We describe crucial design changes within ANewDsc and RS that led to a high-performance implementation without harming the theoretical complexity of the underlying algorithm. With an excerpt of our extensive collection of benchmarks, available online at http://anewdsc.mpi-inf.mpg.de/, we illustrate that the theoretical gain in performance of ANewDsc over other subdivision methods also transfers into practice. These experiments also show that our new implementation outperforms both RS and mature competitors by magnitudes for notoriously hard instances with clustered roots. For all other instances, we avoid almost any overhead by integrating additional optimizations and heuristics.

description: Angesichts wachsender Herausforderungen in der europäischen Landwirtschaft untersucht das EU-Projekt D4AgEcol das Potenzial digitaler Technologien für eine nachhaltigere Landwirtschaft. In Zusammenarbeit mit Partnern aus acht Ländern und mithilfe des ADOPT-Tools werden Adoptionsraten und -geschwindigkeiten von ausgewählten Technologien wie z. B. Virtual
Fencing, Agrarrobotik und Drohnenapplikationen in Workshops mit Praktikern prognostiziert. Die Ergebnisse der Modellierung zeigen, dass bestimmte Technologien wie eine App für Naturschutzanwendungen oder ‚Green Fertilizer Mapping‘ vielversprechende Adoptionsraten aufweisen, während andere in Abgängigkeit von der untersuchten Zielpopulation geringeres Potenzial haben. Sensitivitätsanalysen identifizieren Schlüsselfaktoren wie „Gewinnerwartung“ und „Umwelteffekte“ bei mehreren Technologien als entscheidend für die Adoption. Die beiden Hauptoutputs des Modells, die maximale Adoptionsrate und der Zeitraum bis zum Erreichen dieses Maximums, sind als Orientierungshilfen zu verstehen. Zusätzliche Sensitivitätsanalysen liefern jedoch wertvolle Hinweise auf das Zusammenwirken von Innovation und Zielpopulation.

description: The integration of machine learning (ML) into environmental protection, particularly in sustainable agriculture and forestry, is increasingly vital given the spatio-temporal scale of the data and analysis. Earth observation data from Sentinel-1 (S1), Sentinel-2 (S2), weather, and LiDAR provide valuable insights, but applying ML algorithms to these diverse datasets presents challenges due to their differences in data structure and formats as well as spatial, spectral and temporal resolutions. This research develops a multi-purpose, extensible infrastructure using open-source technologies, implemented within the cloud platform CODE-DE at Julius Kühn-Institut (JKI), to streamline ML applications for geo-located earth observation data. The infrastructure supports diverse data types, including satellite, weather, and LiDAR records, and is adaptable to future ML models. It has been rigorously tested for detecting plant growth stages (BBCH), demonstrating its potential in agricultural analysis. Future work will extend this to detecting tree and shrub growth events. This research contributes to sustainable agriculture by advancing reusable ML solutions for environmental monitoring.

description: It is known that in contrast with the E-mode polarization, the B-mode polarization of the Cosmic Microwave Background cannot be generated by the Compton scattering in the case of scalar mode of metric perturbation. However it is possible to generate the B-mode by the Compton scattering in the case of tensor mode of metric perturbation. For this reason, the ratio of tensor to scalar modes of metric perturbation ($r\sim C_{Bl}/C_{El}$) is estimated by comparing the B-mode power spectrum with the E-mode at least for small $l$. We study the CMB polarization specially B-mode due to the weak interaction of Cosmic Neutrino Background (CNB) and CMB, in addition to the Compton scattering in both cases of scalar and tensor metric perturbations. It is shown that the power spectrum $C_{Bl}$ of the B-mode polarization receives some contributions from scalar and tensor modes, which have effects on the value of $r$-parameter. We also show that the B-mode polarization power spectrum can be used as an indirect probe into the CNB.

description: The colonial war that Portugal was involved in between 1961 and 1974 had a significant impact on veterans and their families. However, it is unclear what the consequences of this war are, in particular with regard to levels of childhood maltreatment (CM) in offspring. Our study aims to analyze the influences of fathers’ war exposure and posttraumatic stress disorder (PTSD) on the offspring's CM and simultaneously test the hypothesis of the intergenerational transmission of father–child CM. Cross-sectional data were collected, using the Childhood Trauma Questionnaire—Short Form, from 203 adult children and 117 fathers. Subjects were distributed according to three conditions based on the father's war exposure status: did not participate in war, or non-war-exposed (NW); participated in war, or war-exposed (W); and war-exposed with PTSD diagnosis (WP). The data were examined using correlations, variance/covariance, and regression analyses. Children of war veterans with PTSD reported more emotional and physical neglect, while their fathers reported increased emotional and physical abuse exposure during their own childhood. Significant father–child CM correlations were found in the war veteran group but less in the war veteran with PTSD group. Father CM predicted 16% of offspring CM of children of war veterans. The father's war-related PTSD might be a risk factor for offspring neglect but potentially a protective one for the father–child abuse transmission. War-exposed fathers without PTSD did transmit their own CM experiences more often. Therefore, father's war exposure and father's war PTSD may each be important variables to take into account in the study of intergenerational transmission of CM.

description: In this work we investigated thin films of the ferrimagnetic insulators YIG and NFO capped with thin Pt layers in terms of the longitudinal spin Seebeck effect (LSSE). The electric response detected in the Pt layer under an out-of-plane temperature gradient can be interpreted as a pure spin current converted into a charge current via the inverse spin Hall effect. Typically, the transverse voltage is the quantity investigated in LSSE measurements (in the range of μV). Here, we present the directly detected DC current (in the range of nA) as an alternative quantity. Furthermore, we investigate the resistance of the Pt layer in the LSSE configuration. We found an influence of the test current on the resistance. The typical shape of the LSSE curve varies for increasing test currents.

description: Obwohl bildbasierte KI-Methoden wie die Lokalisation und die Erkennung von Einzeltieren mittlerweile verstärkt Anwendung im Bereich der Nutztierhaltung finden, stellt die Tieridentifikation, vor allem in Bereichen wie der Schweinehaltung mit homogenen visuellen Tiermerkmalen, nach wie vor große Herausforderungen an bestehende Systeme. Das Ziel der vorliegenden Studie ist diesbezüglich die Entwicklung einer optischen Methode zur Lokalisation und Identifikation von Einzeltieren im Kontext der Schweinehaltung. Durch die modulare Verwendung von vier State-of-the-Art Objektdetektionsmodellen werden die vorhandenen Bildinformationen stufenweise analysiert und lesbare Tier-IDs anhand handelsüblicher Ohrmarken automatisiert bestimmt. Im Ergebnis erreicht der vorgestellte Ansatz eine Erkennungsgenauigkeit von 0,993 bei einer Fehlerrate von 0,007. Im Rahmen weiterer Untersuchungen soll die entwickelte Methode zur Verbesserung von Trackingansätzen und im Kontext spezifischer Anwendungsfälle implementiert werden.
