Creators: name: Emmanuel Chinyere Echeonwu, Moses Okechukwu Onyesolu, Esther Odunayo Oduntan, Ubom Okon Effiong
Publisher: name: Zenodo
Year: 2024

description: This paper introduces the Efficient Vision Transformer (EVT), a deep learning model designed for precise prediction of the Fractional Vegetation Index (FVI) in vegetation monitoring. In order to overcome the limitations of existing methods, EVT incorporates resilient attention mechanisms and streamlined computations, resulting in high accuracy while utilizing fewer computer resources. Its architecture, which includes patch embedding, Transformer encoder layers, and a linear decoder, enables the rapid processing of local information and the comprehensive creation of global context, leading to accurate Vegetation Index predictions. Its ability to process high-resolution aerial images opens up new avenues for monitoring vegetation health and productivity across vast landscapes, providing crucial insights for sustainable land management practices. With 17 million parameters compactly packed in 155 MB and lightning-fast CPU inference duration of 606 milliseconds, EVT demonstrates exceptional efficiency, providing near-real-time insights for precision agriculture and environmental monitoring. The model's computational efficiency and low resource requirements make it accessible to a wide range of users, from researchers and environmental agencies to agricultural organizations and individual farmers, enabling data-driven decision-making on a broader scale. EVT's exceptional accuracy is demonstrated by evaluation measures (Mean Absolute Error of 0.03823, Root Mean Square Error of 0.04582, R-squared value of 0.98556), confirming its reliability across various assessment frameworks and geographical scales. The EVT model represents a groundbreaking solution that offers a future where precision and efficiency come together to support informed decision-making for ecosystem health and sustainable land management.

description: We discuss the microscopic definition of entropy production rate in a model of a dissipative system: a sheared fluid in which the kinetic energy is kept constant via a Gaussian thermostat. The total phase space contraction rate is the sum of two statistically independent contributions: the first one is due to the work of the conservative forces, is independent of the driving force and does not vanish at zero drive, making the system non-conservative also in equilibrium. The second is due to the work of the dissipative forces, and is responsible for the average entropy production; the distribution of its fluctuations is found to verify the Fluctuation Relation of Gallavotti and Cohen. The distribution of the fluctuations of the total phase space contraction rate also verify the Fluctuation Relation. It is compared with the same quantity calculated in the isoenergetic ensemble: we find that the two ensembles are equivalent, as conjectured by Gallavotti. Finally, we discuss the implication of our results for experiments trying to verify the validity of the FR.

Factors Inhibiting and Enabling Performance-Based Financing in Health Care Delivery across Low and Middle-Income Countries: A Scoping Review
Creators: name: Mideksa Adugna

description: Abstract
Background: Emerging financing strategies in the health sector have been developed to improve the impact of investments and enhance healthcare outcomes. One promising approach is Results-based Financing, which establishes a connection between financial incentives and pre-established performance targets. This innovative approach holds the potential to strengthen healthcare delivery and strengthen overall healthcare systems.
Aim: The scoping review endeavored to systematically delineate the body of evidence pertaining to facilitators and barriers to the implementation of performance-based financing within the realm of healthcare provision in low- and middle-income nations.
Methods: The review used Preferred Reporting Items for Systematic Reviews and a Meta-Analysis extension for Scoping Reviews checklist to select, appraise, and report the findings. We searched PubMed, Web of Science, and Google Scholar databases and grey literature published between January 2000 and March 2022. We conducted the abstract screening with two independent reviewers. We also performed full-article screening. We used the six methodological frameworks proposed by Arksey and O'Malley. The results were thematically analyzed.
Results: Of the 1071 searched studies, 34 met the eligibility criteria. 41% of the studies were descriptive, 26% cross-sectional, 18% trial, and 15% cohort studies. The enabling and inhibiting factors of performance-based financing in healthcare delivery have been identified. Moreover, the review revealed that performance-based financing's influence on service delivery is context-specific.
Conclusion: The facilitators and impediments to the effectiveness of performance-based financing in enhancing service delivery are contingent upon a holistic comprehension of the contextual factors, meticulous design, and efficient execution. Factors such as the level of care facilities, presence of community-based initiatives, stakeholder involvement, and participatory design emerge as key facilitators. Conversely, barriers such as communication obstacles, inadequacies in the PBF models, and deficiencies in the healthcare workforce are recognized as inhibitors. By harnessing the insights derived from a multitude of evidence incorporated in this scrutiny, stakeholders can deftly navigate the intricacies of performance-based financing, while also considering the prospective areas for further exploration and research..

description: A short survey of the semiclassical periodic orbit theory, initiated by M. Gutzwiller and generalized by many other authors, is given. Via so-called semiclassical trace formmulae, gross-shell effects in bound fermion systems can be interpreted in terms of a few periodic orbits of the corresponding classical systems. In integrable systems, these are usually the shortest members of the most degenerate families or orbits, but in some systems also less degenerate orbits can determine the gross-shell structure. Applications to nuclei, metal clusters, semiconductor nanostructures, and trapped dilute atom gases are discussed.

description: Nirgendwo auf der Erde ist die Erwärmung durch die Emission von anthropogenen Treibhausgasen so hoch wie in der Arktis. Das hat neben dem Abschmelzen von Eis und Schnee und der Erwärmung des Nordpolarmeers auch Auswirkungen auf die Vegetationsbedeckung der Tundra. Das Ökosystem der Tundra ist relativ jung und hat sich erst nach der letzten Eiszeit gebildet. Gegenwärtig wandelt es sich stark unter dem Einfluss des vom Menschen verursachten Klimawandels. Die sichtbarste Veränderung ist die Ausbreitung von Strauchvegetation auf Kosten der flächenmäßig vorherrschenden Gräser, Moose und Flechten. Diese Verbuschung der Tundra ist mit komplexen Rückwirkungen auf das regionale und sogar auf das globale Klima verbunden. Bis zum Ende des 21. Jahrhunderts wird sich dieser Prozess verstärken. The tundra in transition: Nowhere on earth the warming due to the emission of anthropogenic greenhouse gases is as high as in the Arctic. In addition to the melting of ice and snow and the warming of the Arctic Ocean, this too has an impact on the vegetation cover of the tundra. The tundra ecosystem is relatively young and only formed after the last ice age. It is currently undergoing major changes under the influence of human-induced climate change. The most visible change is the spread of shrub vegetation at the expense of the predominant grasses, mosses and lichens. This shrubification of the tundra is associated with complex feedbacks on regional and even global climate. By the end of the 21st century, this process will intensify. La tundra cambiando: En ningún lugar del planeta el calentamiento causado por la emisión de gases de efecto invernadero antropogénicos es tan elevado como en el Ártico. Además del derretimiento del hielo y la nieve y el calentamiento del océano Ártico, esto también afecta a la cubierta vegetal de la tundra. El ecosistema de la tundra es relativamente joven y sólo se formó después de la última edad de hielo. Actualmente está sufriendo grandes cambios bajo la influencia del cambio climático inducido por el hombre. El cambio más visible es la expansión de la vegetación arbustiva en detrimento de las hierbas, musgos y líquenes predominantes. Esta invasión de la tundra por parte de los arbustos está asociada a complejas reacciones sobre el clima regional e incluso mundial. A finales del siglo XXI, este proceso se intensificará.

description: We present new grids of pre-main sequence (PMS) tracks for stars in the mass range 0.1 to 7.0 Msun. The computations were performed for four different metallicities (Z=0.01, 0.02, 0.03 and 0.04). A fifth table has been computed for the solar composition (Z=0.02), including a moderate overshooting. We describe the update in the physics of the Grenoble stellar evolution code which concerns mostly changes in the equation of state (EOS) adopting the formalism proposed by Pols et al. (1995) and in the treatment of the boundary condition. Comparisons of our models with other grids demonstrate the validity of this EOS in the domain of very low-mass stars. Finally, we present a new server dedicated to PMS stellar evolution which allows the determination of stellar parameters from observational data, the calculation of isochrones, the retrieval of evolutionary files and the possibility to generate graphic outputs.

description: We study supersymmetric domain walls on S_1/Z_2 orbifolds. The supergravity solutions in the bulk are given by the attractor equation associated with Calabi-Yau spaces and have a naked space-time singularity at some |y_s|. We are looking for possibilities to cut off this singularity with the second wall by a stringy mechanism. We use the collapse of the CY cycle at |y_c| which happens before and at a finite distance from the space-time singularity. In our example with three Kahler moduli the second wall is at the end of the moduli space at |y_c| where also the enhancement of SU(2) gauge symmetry takes place so that |y_e|=|y_c|< |y_s|. The physics of the excision of a naked singularity via the enhancon in the context of domain wall has an interpretation on the heterotic side related to R -> 1/R duality. The position of the enhancon is given by the equation R(|y_e|)=1.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

description: Field experiments are often difficult and expensive to make. To bypass these issues, industrial companies have developed computational codes. These codes intend to be representative of the physical system, but come with a certain amount of problems. The code intends to be as close as possible to the physical system. It turns out that, despite continuous code development, the difference between the code outputs and experiments can remain significant. Two kinds of uncertainties are observed. The first one comes from the difference between the physical phenomenon and the values recorded experimentally. The second concerns the gap between the code and the physical system. To reduce this difference, often named model bias, discrepancy, or model error, computer codes are generally complexified in order to make them more realistic. These improvements lead to time consuming codes. Moreover, a code often depends on parameters to be set by the user to make the code as close as possible to field data. This estimation task is called calibration. This paper proposes a review of Bayesian calibration methods and is based on an application case which makes it possible to discuss the various methodological choices and to illustrate their divergences. This example is based on a code used to predict the power of a photovoltaic plant.

Using SVM regression and classification procedures, we have created global models of atomic masses, beta-decay halflives, and ground-state spins and parities. These models exhibit performance in both data-fitting and prediction that is comparable to that of the best global models from nuclear phenomenology and microscopic theory, as well as the best statistical models based on multilayer feedforward neural networks.

description: We observe G117-B15A, the most precise optical clock known, to measure the rate of change of the main pulsation period of this blue-edge DAV white dwarf. Even though the obtained value is only within 1 sigma, Pdot = (2.3 +/- 1.4) x 10^{-15} s/s, it is already constraining the evolutionary timescale of this cooling white dwarf star.

description: Object detection in geospatial imagery plays a critical role in various applications, including land-use analysis, environmental monitoring, and disaster response. Traditional computer vision and image processing techniques employed for object detection can be labor-intensive and time-consuming, hindering the efficiency of processing geospatial data, particularly for real-time applications. Deep learning, however, offers a powerful alternative with its ability to automate feature extraction and achieve superior classification performance. This study investigates the application of Faster Region-based Convolutional Neural Network (Faster R-CNN), a state-of-the-art deep learning model, for object detection in UAV imagery. The research methodology encompasses the acquisition of UAV data, followed by the careful annotation and preparation of a training and validation dataset encompassing diverse object classes. Annotations adhere to the PASCAL VOC standard, ensuring data quality and facilitating model training. The Faster R-CNN model is then employed for object detection within the prepared dataset. To assess the effectiveness of the trained model, a comprehensive validation process is undertaken, incorporating both qualitative and quantitative evaluation methods. The experimental results demonstrate a promising mean average precision (mAP) of 0.87 across a representative sample of test images, signifying the model's ability to accurately classify and localize objects within UAV imagery. These findings highlight the potential of deep learning techniques in empowering geospatial analysts with robust and efficient tools for visual recognition tasks. By automating feature extraction and achieving superior classification accuracy, deep learning paves the way for faster and more comprehensive analysis of geospatial data, ultimately contributing to more informed decision-making processes within the field.

description: Weltweit spielen Großstaudämme eine immer wichtigere Rolle für die »erneuerbare« Energieversorgung und in den vielen Trockengebieten der Erde für die Bewässerung und Ausweitung der Landwirtschaft. Einige neuere Staudämme sind spektakuläre Riesenprojekte. Großstaudammprojekte sind aber inzwischen sehr umstritten, sie sind Konfliktherde; sie verändern die Landnutzung diametral, sie vertreiben die eingesessene Bevölkerung und zerstören deren Lebensgrundlagen. Die ökologischen und ökonomischen Auswirkungen sind nicht nur positiv, sondern sie weisen in erheblichem Maße auch negative Folgen auf. Dazu kommt, dass Staudamm und Nutzung der Wasserspeicher auch nur eine begrenzte Zeit möglich ist. Large water dams for energy generation and irrigation and its social problems: An introduction: Large dams play an increasingly important role worldwide for the renewable energy supply and in the many arid regions of the world for irrigation and the expansion of agriculture. Some of the newer dams are spectacular giant projects. Large dam projects are now very controversial, they are sources of conflicts; they change land use diametrically, they drive out the local population and destroy their livelihoods. The ecological and economic effects are not only positive, they also have negative consequences to a considerable extent. In addition, the dam and the use of the water reservoir are only possible for a limited time. Grandes represas para la generación de energía y proyectos de irrigación y sus conflictos sociales: Una introduccion: Las grandes represas desempeñan un papel cada vez más importante en todo el mundo en la producción de energia »renovable« y en las muchas regiones áridas del mundo para mejorar el riego y la expansión agricola. Algunas de las represas más nuevas son proyectos gigantescos. Muchos proyectos de represas tienen sus lados negativos y son fuentes de conflictos; cambian diametralmente el uso de la tierra, conducen al desalojos de la población local y destruyen sus fuentes de trabajo, también los efectos eco­lógicos y económicos son en gran medida negativos. Además el uso de las represan tienen un tiempo limitado y su desmontaje es costoso.

description: The dynamic mechanism of joint proactive caching and cache replacement, which involves placing content items close to cache-enabled edge devices ahead of time until they are requested, is a promising technique for enhancing traffic offloading and relieving heavy network loads. However, due to limited edge cache capacity and wireless transmission resources, accurately predicting users’ future requests and performing dynamic caching is crucial to effectively utilizing these limited resources. This paper investigates joint proactive caching and cache replacement strategies in a general mobile edge computing (MEC) network with multiple users under a cloud-edge-device collaboration architecture. The joint optimization problem is formulated as a markov decision process (MDP) problem with an infinite range of average network load costs, aiming to reduce network load traffic while efficiently utilizing the limited available transport resources. To address this issue, we design an Attention Weighted Deep Deterministic Policy Gradient (AWD2PG) model, which uses attention weights to allocate the number of channels from server to user, and applies deep deterministic policies on both user and server sides for Cache decision-making, so as to achieve the purpose of reducing network traffic load and improving network and cache resource utilization. We verify the convergence of the corresponding algorithms and demonstrate the effectiveness of the proposed AWD2PG strategy and benchmark in reducing network load and improving hit rate.
Spin-polarized ballistic conduction through correlated Au-NiMnSb-Au heterostructures

description: We examine the ballistic conduction through Au-NiMnSb-Au heterostructures consisting of up to four units of NiMnSb in the scattering region. We investigate the dependence of the transmission function computed within the local spin density approximation (LSDA) of the density functional theory (DFT) on the number of half-metallic units in the scattering region. For a single NiMnSb unit the transmission function displays a spin polarization of around 50 % in a window of 1 eV centered around the Fermi level. By increasing the number of layers an almost complete spin polarization of the transmission is obtained in the same energy window. Supplementing the DFT-LSDA calculations with local electronic interactions, of Hubbard-type on the Mn sites, leads to a hybridization between the interface and many-body states. The significant reduction of the spin polarization seen in the density of states is not apparent in the spin-polarization of the conduction electron transmission, which suggests the localized nature of the hybridized interface and many-body induced states.

description: High-quality Hipparcos data for a complete sample of nearly 12000 main-sequence and subgiant stars, together with Padua isochrones, are used to constrain the star-formation history of the solar neigbourhood and the processes that stochastically accelerate disk stars. The velocity dispersion of a coeval group of stars is found to increase with time from ~8 kms at birth as t^{0.33}. In the fits, the slope of the IMF near 1 Msun proves to be degenerate with the rate at which the star-formation rate declines. If the slope of the IMF is to lie near Salpeter's value, -2.35, the star-formation rate has to be very nearly constant. The age of the solar neighbourhood is found to be 11.2+/-0.75 Gyr with remarkably little sensitivity to variations in the assumed metallicity distribution of old disk stars. This age is only a Gyr younger than the age of the oldest globular clusters when the same isochrones and distance scale are employed. It is compatible with current indications of the redshift of luminous galaxy formation only if there is a large cosmological constant. A younger age is formally excluded because it provides a poor fit to the number density of red stars. Since this density is subject to a significantly uncertain selection function, ages as low as 9 Gyr are plausible even though they lie outside our formal error bars.
