description: We report on a new method to extract thermodynamic properties from the density of partition function zeroes on finite lattices. This allows direct determination of the order and strength of phase transitions numerically. Furthermore, it enables efficient distinguishing between first- and second-order transitions, elucidates crossover between them and illuminates the origins of finite-size scaling. The power of the method is illustrated in typical applications for both Fisher and Lee-Yang zeroes.

description: Um Schüler*innen ein besseres Verständnis für Fledermäuse zu vermitteln und gleichzeitig den Artenschutz heimischer Säugetiere zu fördern, wurde ein Fledermausdetektor zur Fertigung im technikbezogenen Unterricht entwickelt. Der B@t-Detektor kombiniert im Technikunterricht fächerübergreifende Aspekte aus der Biologie und Physik mit Gamification-Elementen, um das Interesse an und das Verständnis für Fledermäuse(n) bei Lernenden zu fördern. In der Lehrkräfteausbildung wird durch die Integration dieses Detektors in didaktische Seminare angehenden Lehrkräften eine praxisnahe und interaktive Möglichkeit vorgestellt, die Erfassung und Analyse von Fledermausaktivitäten zu erleben. Die Gamification-Elemente sind angelehnt an ein GamePad und geben neben den in Hörschall umgewandelten Fledermausrufen auch optische und haptische Signale. Diese innovative Herangehensweise unterstützt nicht nur die fachwissenschaftliche Wissensvermittlung, sondern fördert auch die Entwicklung didaktischer Fähigkeiten und die Anwendung moderner Technologie im Bildungsbereich. Der Fledermausdetektor dient somit als wertvolles Werkzeug, um zukünftige Lehrkräfte auf eine interaktive und praxisorientierte Unterrichtsgestaltung vorzubereiten. In diesem Beitrag wird die Konstruktion des Fledermausdetektors mittels Maker-Werkzeugen vorgestellt und ein Einblick in die derzeitige Forschung zum Einsatz des Detektors in Hochschulseminaren gewährt. Ziel ist es, auf Basis empirischer Daten den aktiven Einsatz in der Schule bestmöglich vorzubereiten.

description: To design well-being and smart communities, it is important to know what street scapes/layouts are good for people experience with comfortableness, activeness, beautifulness, etc. For that purpose, walkability is one of the key performance indicators expressing the environmental quality of a street. As the first step for creating the well-being smart communities, this study attempts to evaluate the influence of street scapes/layouts by using street images taken by a volunteered geographic information application, Mapillary and a image assessment with machine learning technique. We conduct street experiments in a district in Tokyo, Japan for comparing the score of the quality of street image with the answers of questionnaire on the street. The result suggests that score of quality of images is not consistent with the street experience for people such as comfortableness, secureness, and activeness.

description: A procedure of testing the $f(R)$-theory of gravity is discussed. The latter is an extension of the general theory of relativity (GR). In order this extended theory (in some variant) to be really confirmed as a more precise theory it must be tested. To do that we first have to solve an equation generalizing Einstein's equation in the GR. However, solving this generalized Einstein's equation is often very hard, even it is impossible in general to find an exact solution. It is why the perturbation method for solving this equation is used. In a recent work \cite{Ky:2018fer} a perturbation method was applied to the $f(R)$-theory of gravity in a central gravitational field which is a good approximation in many circumstances. There, perturbative solutions were found for a general form and some special forms of $f(R)$. These solutions may allow us to test an $f(R)$-theory of gravity by calculating some quantities which can be verified later by the experiment (observation). In \cite{Ky:2018fer} an illustration was made on the case $f(R)=R+λR^2$. For this case, in the present article, the orbital precession of S2 orbiting around Sgr A* is calculated in a higher-order of approximation. The $f(R)$-theory of gravity should be also tested for other variants of $f(R)$ not considered yet in \cite{Ky:2018fer}. Here, several representative variants are considered and in each case the orbital precession is calculated for the Sun--Mercury- and the Sgr A*--S2 gravitational systems so that it can be compared with the value observed by a (future) experiment. Following the same method of \cite{Ky:2018fer} a light bending angle for an $f(R)$ model in a central gravitational field can be also calculated and it could be a useful exercise.

Theory of Unified Spacetime

Publisher: name: Zenodo

Subjects: subject: Quantum physics
subject: Theoretical physics

description: The Theory of Unified Spacetime Theory (UST) represents a paradigm shift in our understanding of the universe. This innovative framework unites quantum mechanics and classical gravity into a single, cohesive law of nature. Rather than treating gravity as an outlier or forcing quantum principles into an ill-fitting classical mold, UST elegantly posits that spacetime itself begins in a repulsive, quantum-dominated state. Only when local energy densities exceed a critical threshold—the Tucker Point—does the familiar, attractive behavior of classical gravity emerge.

At its heart, UST builds on a unified action that naturally blends all four fundamental forces into one coherent framework. By incorporating a density-dependent scalar field that triggers a phase transition from a quantum repulsive regime to a classical attractive one, the theory not only eliminates the singularities that have long troubled General Relativity but also reproduces key cosmological phenomena such as cosmic acceleration without invoking mysterious dark energy components.

What makes UST especially persuasive is its robust mathematical formalism and its clear set of testable predictions. From subtle oscillations in the Hubble parameter near the transition point to distinctive gravitational lensing profiles and measurable shifts in gravitational wave signals, the theory opens exciting new avenues for experimental validation. Moreover, its innovative approach addresses longstanding puzzles in physics—from the matter–antimatter asymmetry to the strong CP problem—by providing fresh insights grounded in fundamental principles.

Designed with both theoretical rigor and observational relevance in mind, Unified Spacetime Theory offers a promising roadmap toward a deeper understanding of the cosmos. Its potential to bridge the gap between quantum theory and classical gravity positions it as an attractive candidate for the next major breakthrough in theoretical physics. Whether you’re exploring the intricate dynamics of the early universe or probing the mysterious interiors of black holes, UST provides a compelling, unifying narrative that challenges conventional wisdom and inspires future discoveries.

This comprehensive framework, developed with precision and creativity, invites researchers to test its predictions and refine our grasp of spacetime itself. Embrace the journey toward unification—where quantum repulsion meets classical attraction—and join the forefront of cutting-edge theoretical physics with Unified Spacetime Theory.

description: With the need for optimisation based supervisory controllers for complex energy systems, comes the need for reduced order system models representing not only the non-linear characteristics of the components, but also certain unknown process dynamics like their internal control logic. We present in this paper an extensive literature study of existing methods and a rational modelling procedure based on the grey-box methodology that satisfies the necessary characteristics for models to be applied in an economic-MPC of a real-world polygeneration system at the Offenburg University of Applied Sciences. The engineering application of the models and their fitting coefficients are shared in this paper. Finally, the models are evaluated against experimental data and the efficacy of the methodology is discussed based on quantitative and qualitative arguments.

description: Control of apple trees productivity, during the first years of bearing is essential for maintaining high and regular yields in the entire exploitation period. Removing redundant fruitlets has to be done every year, either by hand or using chemical thinning compounds. The object of this research was to optimize the intensity of chemical fruit thinning according to yield and income in Golden Delicious apple orchard, in the second and third fruiting season. Three rates of 6- benzyladenine (BA) were applied to thin fruits: 100, 150 and 200 mg/l. Calculated income decreased after BA application by 12,5-21,5% compared to the untreated group. The most efficient treatment was 200 mg/l BA, regarding average fruit weight, diameter and yield which nearly reached the planned yields. Additional correction of fruit number per tree by hand thinning was the least necessary after treatment with 200 mg/l BA.

description: At present, new approaches for the use of Multirotor Unmanned Aerial Vehicle or multirotor drones in high precision optical applications are rising. However, the optical turbulence effects generated by multirotor drones are not entirely understood. These optical effects can reduce the performance of the optical instruments that they transport. This paper presents measurements of the wavefront deformation generated by the temperature fluctuations and the airflow of a drone's propulsion system. To do so, we used a single arm of a DJI S800 EVO Hexacopter (professional drone) and measured its operating temperature with a commercial infrared camera. The resulting temperature variation, between a switched-off propulsion system at room temperature and one running at its maximum performance, was 34.2° C. Later, we performed two different interferometric tests, Takeda's method, and the phase-shifting technique, using a ZYGO interferometer. These tests show that the total deformation over an incident wavefront to the propeller airflow is lower than 0.074 λPV and 0.007 λRMS (HeNe laser, λ=633nm). We conclude that the optical turbulence produced by a drone propulsion system is negligible.

Brain MRI reconstruction
Various disease diagnosis

description: Abstract: Background: Unsupervised learning can discover various unseen abnormalities, relying on large-scale unannotated medical images of healthy subjects. Towards this, unsupervised methods reconstruct a 2D/3D single medical image to detect outliers either in the learned feature space or from high reconstruction loss. However, without considering continuity between multiple adjacent slices, they cannot directly discriminate diseases composed of the accumulation of subtle anatomical anomalies, such as Alzheimer’s disease (AD). Moreover, no study has shown how unsupervised anomaly detection is associated with either disease stages, various (i.e., more than two types of) diseases, or multi-sequence magnetic resonance imaging (MRI) scans. Results: We propose unsupervised medical anomaly detection generative adversarial network (MADGAN), a novel two-step method using GAN-based multiple adjacent brain MRI slice reconstruction to detect brain anomalies at different stages on multi-sequence structural MRI: (Reconstruction) Wasserstein loss with Gradient Penalty + 100 ℓ1 loss—trained on 3 healthy brain axial MRI slices to reconstruct the next 3 ones—reconstructs unseen healthy/abnormal scans; (Diagnosis) Average ℓ2 loss per scan discriminates them, comparing the ground truth/reconstructed slices. For training, we use two different datasets composed of 1133 healthy T1-weighted (T1) and 135 healthy contrast-enhanced T1 (T1c) brain MRI scans for detecting AD and brain metastases/various diseases, respectively. Our self-attention MADGAN can detect AD on T1 scans at a very early stage, mild cognitive impairment (MCI), with area under the curve (AUC) 0.727, and AD at a late stage with AUC 0.894, while detecting brain metastases on T1c scans with AUC 0.921. Conclusions: Similar to physicians’ way of performing a diagnosis, using massive healthy training data, our first multiple MRI slice reconstruction approach, MADGAN, can reliably predict the next 3 slices from the previous 3 ones only for unseen healthy images. As the first unsupervised various disease diagnosis, MADGAN can reliably detect the accumulation of subtle anatomical anomalies and hyper-intense enhancing lesions, such as (especially late-stage) AD and brain metastases on multi-sequence MRI scans.
Efficient Pose Selection for Interactive Camera Calibration

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: The choice of poses for camera calibration with planar patterns is only rarely considered - yet the calibration precision heavily depends on it. This work presents a pose selection method that finds a compact and robust set of calibration poses and is suitable for interactive calibration. Consequently, singular poses that would lead to an unreliable solution are avoided explicitly, while poses reducing the uncertainty of the calibration are favoured. For this, we use uncertainty propagation. Our method takes advantage of a self-identifying calibration pattern to track the camera pose in real-time. This allows to iteratively guide the user to the target poses, until the desired quality level is reached. Therefore, only a sparse set of key-frames is needed for calibration. The method is evaluated on separate training and testing sets, as well as on synthetic data. Our approach performs better than comparable solutions while requiring 30% less calibration frames.

description: Annomus Halstead, new genus
 Type species. Annomus bolivianus Halstead, new species, here designated.
 Discussion. Two specimens (male and female) of a new, small Bolivian beetle belonging to the Silvaninae were kindly sent to the author by Dr. M. C. Thomas for study and description. The relationship with other genera within the subfamily is not clear. However, this new genus has head and pronotal puncturation that is reminiscent of the widespread Monanus (Monanus) concinnulus (Walker) and also several other members of this subgenus. Of course, the pronotum of Monanus species (both those of Monanus (Monanus) and Monanus (Monanops)) differs from that of the new genus in many characters including for example in having lateral marginal denticles, about 8–14, not 5 large teeth, and having quite different genitalia with a long and thin median strut (Halstead 1993), unlike the broad and relatively short one of Annomus.
 Diagnosis. Characters which, apart from the general facies probably have significance for recognition of other members of Annomus, include the following: male genitalia of similar form to that illustrated (Fig. 121–122); a pair of setae on each pronotal lateral tooth; large punctures producing reticulation on pronotum; eyes large and prominent, equally exposed above and below; tarsal formula 5-5-5, with tarsomeres 1–3 each produced below to form an obvious lobe (Fig. 120).

Publisher: name: Zenodo
Year: 2024

description: Blockchain technology has the potential to significantly enhance agricultural supply chain efficiency, leading to increased yields and profitability. This paper explores how blockchain can address key challenges in agriculture, such as fraud, inefficiencies, and lack of transparency. Through decentralized, immutable ledgers, blockchain ensures real-time traceability and accountability in the movement of goods, reducing the risk of spoilage and fraud. Smart contracts are examined as tools for automating transactions between farmers and buyers, streamlining payments, and minimizing disputes. The ability to trace produce from farm to market also boosts consumer trust in organic and sustainably grown products, opening new revenue streams for farmers. Furthermore, improved traceability helps optimize logistics and reduce post-harvest losses by ensuring that high-quality produce reaches markets promptly. The paper highlights case studies where blockchain has minimized inefficiencies and fostered greater coordination across the supply chain, enabling farmers to secure better pricing, reduce intermediaries, and access timely market data. By leveraging blockchain, agricultural stakeholders can achieve more transparent, efficient, and profitable operations while also contributing to sustainable farming practices. Challenges such as the cost of implementation and the digital literacy required for widespread adoption are discussed, alongside the long-term potential for blockchain to reshape the global agricultural landscape.

description: The two-dimensional Ising model with Brascamp-Kunz boundary conditions has a partition function more amenable to analysis than its counterpart on a torus. This fact is exploited to exactly determine the full finite-size scaling behaviour of the Fisher zeroes of the model. Moreover, exact results are also determined for the scaling of the specific heat at criticality, for the specific-heat peak and for the pseudocritical points. All corrections to scaling are found to be analytic and the shift exponent $λ$ does not coincide with the inverse of the correlation length exponent $1/ν$.

 SIZE: Medium to large (10–50 mm).
 FEEDING GROUP: Predators.
 TOLERANCE VALUE: 2 (Low).
 DIAGNOSIS: Adults dark or gray brown with golden or light brown patterns Male genitalic structures are highly variable throughout the family, usually with uniquely shaped paraprocts or aedeagus with species-specific spine patches. The female subgenital plate is also highly variable. The nymphs usually have high contrast patterns similar to Perlidae stoneflies, but lack branched gills on the thoracic segments although one genus, Megarcys has unbranched fingerlike gills on the thorax (Fig. 233) and many species have submental gills (Fig. 244). Gill remnants often persist in adult forms. As in other Systellognatha, the labium has a deep notch and paraglossa extending beyond glossa (Fig. 8). In contrast to Chloroperlidae in particular, the hind wing pads are divergent from the body axis (Fig. 22).
 DISCUSSION: Perlodid stoneflies are most commonly found in flowing waters under stones and in snags and leaf packs. Occasionally, they are found along the edges of cold lakes.

description: In this paper, machine learning methods are developed to identify and classify maps from online sources. Given any image, our methods can be used to answer three questions: is it a map, which geographic region is this map about, and what projection is used in the map? A total of 1000 images are collected using Google Images to provide data for non-maps and maps that cover different geographic regions with different projections. Three machine learning methods are tested: multilayer perceptrons (MLP), support vector machine (SVM), and convolutional neural network (CNN). Each method is evaluated by how accurate it can be used to correctly identify and classify a given image. For map identification, all three methods can be used to obtain results with high accuracy, while for map classification based on region and projection, only SVM and CNN perform well.

description: Most economists agree with the proposition that a minimum wage set above the market clearing equilibrium wage will cause unemployment. What happens when a minimum wage is set below the equilibrium wage is, however less clear. This is partly because the literature shows that the effect of a minimum wage will depend on the reason for its implementation. The literature also shows that the effect of a minimum wage depends on a range of macro level considerations. In this paper the international literature on the effects of a minimum wages is reviewed, and lessons are drawn for the implementation of a minimum wage in South African agriculture.
Detecting Orbital Angular Momentum of Light in Satellite-to-Ground Quantum Communications

description: Satellite-based quantum communications enable a bright future for global-scale information security. However, the spin orbital momentum of light, currently used in many mainstream quantum communication systems, only allows for quantum encoding in a two-dimensional Hilbert space. The orbital angular momentum (OAM) of light, on the other hand, enables quantum encoding in higher-dimensional Hilbert spaces, opening up new opportunities for high-capacity quantum communications. Due to its turbulence-induced decoherence effects, however, the atmospheric channel may limit the practical usage of OAM. In order to determine whether OAM is useful for satellite-based quantum communications, we numerically investigate the detection likelihoods for OAM states that traverse satellite-to-ground channels. We show that the use of OAM through such channels is in fact feasible. We use our new results to then investigate design specifications that could improve OAM detection - particularly the use of advanced adaptive optics techniques. Finally, we discuss how our work provides new insights into future implementations of space-based OAM systems within the context of quantum communications.

description: The concept of accountability, as articulated by Glymn (1985), emerges as a fundamental and indispensable theme shaping the functioning of both private and public sectors. With roots traceable to ancient times, accountability stands as a cornerstone principle influencing organizational governance. This abstract explores the historical foundation of accountability and draws attention to its enduring significance in contemporary contexts. Glymn's assertion underscores accountability's pervasive nature, permeating diverse sectors and organizational structures. The New Testament, specifically the parable recounted by Matthew (25 Vs 14 - 30), provides a poignant narrative illustrating the essence of accountability. The parable revolves around a man entrusting his property to three servants, encapsulating the inherent responsibility associated with stewardship. In essence, accountability serves as a guiding principle, emphasizing the need for individuals and entities to be answerable for the resources, tasks, and responsibilities entrusted to them. The exploration of this theme extends beyond historical perspectives to underscore its relevance in modern organizational dynamics. The narrative from Matthew's Gospel serves as a timeless allegory, highlighting the consequences of faithful stewardship and the implications of negligence. As organizations grapple with evolving challenges and heightened expectations, the abstract advocates for a renewed focus on accountability. Whether in the private or public sector, the enduring nature of this concept resonates through historical narratives and remains pivotal in shaping ethical conduct, transparency, and effective governance. Understanding and embracing accountability not only aligns with historical wisdom but also establishes a robust foundation for responsible and sustainable organizational practices.

description: The carriers of electric current in a metal are quasiparticles dressed by electron-electron interactions, which have a larger effective mass $m^*$ and a smaller quasiparticle weight $z$ than non-interacting carriers. If the momentum dependence of the self-energy can be neglected, the effective mass enhancement and quasiparticle weight of quasiparticles at the Fermi energy are simply related by $z=m/m^*$ ($m$=bare mass). We propose that both superconductivity and ferromagnetism in metals are driven by quasiparticle 'undressing', i.e., that the correlations between quasiparticles that give rise to the collective state are associated with an increase in $z$ and a corresponding decrease in $m^*$ of the carriers. Undressing gives rise to lowering of kinetic energy, which provides the condensation energy for the collective state. In contrast, in conventional descriptions of superconductivity and ferromagnetism the transitions to these collective states result in $increase$ in kinetic energy of the carriers and are driven by lowering of potential energy and exchange energy respectively.

description: There has been a recent heavy emphasis on the development of integrated pest management strategies. Entomopathogenic fungi, representing a class of biological control agents, have been widely used in the field of pest management. The objective of this work was to isolate different species of fungi and to evaluate their virulence against the destructive, invasive, red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae). In this study, the two pathogenic fungi species isolated from dead diseased RPW were identified as Metarhizium anisopliae var. anisopliae (Metschn.) (Hypocreales: Clavipitaceae) and Fusarium oxysporum Schlecht. (Hypocreales: Tuberculariaceae). Identifications were verified using the methods of synthetically using colony culture characteristics, spore morphology, and rDNA-ITS sequence amplification. Bioassay results showed that M. anisopliae var. anisopliae exhibited a significantly higher corrected mortality than F. oxysporum (90.92% vs. 77.28%) in fourth instar RPW larvae 12 days after treatment with a conidial density of 1.0×1010 conidia/mL, as well as lower LC50 (and LT50) values. The LC50 values for the two fungal strains were 3.2×108 and 4.8×108 conidia/mL, respectively, and LT50 values were 5.9 and 8.4 d, respectively. These results demonstrate that both of the fungi can potentially be used as microbial control agents against this widespread pest. However, M. anisopliae var. anisopliae showed relatively higher insecticidal activity than F. oxysporum.

description: We present a simple precision-method to quickly and accurately measure the diameters of Gaussian beams, Airy spots, and central peak of Bessel beams ranging from the sub-millimeter to many centimeters without specialized equipment. Simply moving a wire through the beam and recording the relative losses using an optical power meter, one can easily measure the beam diameters with a precision of 1%. The accuracy of this method has been experimentally verified for Gaussian beams down to the limit of a commercial slit-based beam profiler (3%).

description: In 1975, M. M. Choban introduced a new topology on the set of all closed subsets of a topological space, similar to the Tychonoff topology but weaker than it. In 1998, G. Dimov and D. Vakarelov used a generalized version of this new topology, calling it Tychonoff-type topology. The present paper is devoted to a detailed study of Tychonoff-type topologies on an arbitrary family M of subsets of a set X. When M contains all singletons, a description of all Tychonoff-type topologies O on M is given. The continuous maps of a special form between spaces of the type (M,O) are described in an isomorphism theorem. The problem of commutability between hyperspaces and subspaces with respect to a Tychonoff-type topology} is investigated as well. Some topological properties of the hyperspaces (M,O) with Tychonoff-type topologies O are briefly discussed.

description: The economic feasibility of using composted manure from KwaZulu-Natal midlands feedlots in combination with commercial N in production of dryland grain maize [Zea mays (L.)] was evaluated. Effective disposal of large quantities of manure from large scale feedlots is a concern. Yield data from Cedara experiment station were used to estimate a quadratic production function where maize grain yield is a function of manure and commercial fertiliser N application rates. Four rates of commercial N (0, 50, 100 and 200 kg ha-1) and five rates of composted feedlot manure (0, 5, 10, 20 and 30 t ha-1, as is basis) in a factorial arrangement were applied to dryland maize. The production function estimate was used to determine the combination of composted manure and commercial N, which maximized net returns. The results suggest that a compost application rate of 15 t ha-1 with 20 kg ha-1 of commercial N would be economically feasible when the price of commercial N, including application charges, is R4.50 kg-1 and the price of compost R77.20 t-1. Once the price of compost reaches R95.00 t-1 compost use is no longer economically feasible.

description: We observe the magnetic oscillation of electric conductance in the two-dimensional InAs/GaSb quantum spin Hall insulator. Its insulating bulk origin is unambiguously demonstrated by the antiphase oscillations of the conductance and the resistance. Characteristically, the in-gap oscillation frequency is higher than the Shubnikov-de Haas oscillation close to the conduction band edge in the metallic regime. The temperature dependence shows both thermal activation and smearing effects, which cannot be described by the Lifshitz-Kosevich theory. A two-band Bernevig-Hughes-Zhang model with a large quasiparticle self-energy in the insulating regime is proposed to capture the main properties of the in-gap oscillations.

description: The principal goal of this study is to provide economic analysis of value added in the context of problems of competitive position in enterprises. A relationship presented in the literature that occurs between competitive position in the enterprise and its ability to generate value added. The selected tools for measurement of competitive position in the enterprise were presented, among which the authors included enterprise concentration rate and economic value added. EVA concept was also characterized. The empirical investigations focused on the companies listed in the Warsaw Stock Exchange. Based on the empirical analysis, the study found a significant difference between the place in the ranking of the value added and the degree of enterprise's participation in the market.
