description: The present work attempts based on the analysis of linear structure equation models, to compile regulation factors of the success of agricultural enterprises at the management level. For generation and evaluation reasons, the findings from the factor research are the focus of the study. After introducing the topic of success factor research, current empirical methods are compared based on their explanatory potential. As a result of the comparison, it was decided to apply a confirmatory approach. Linear structure equation models with latent variables are applied to the database. The explanation of the method occurs in chapter 3. They are applied on the factor analysis as well as the path analysis because linear structural equation models concern both. In the following, the database, which is based on the results of annual financial statements of agricultural enterprises from southern Saxony-Anhalt, is introduced. Following, there occurs the characterisation and discussion of the data. The next chapter contains the results of the partial analytical investigation of possible variables which may influence the success of agricultural enterprises. Embedded in a theoretical framework, the basic theoretical hypotheses were formulated. The theoretical basis of research hypotheses is based on the management model for enterprises, which makes a distinction between management level and other dimensions of business administration. Based on these results, and on the results of the descriptive evaluation, concrete research hypotheses are formulated. The hypotheses imply a positive effect of the single dimensions of business administration, such as market orientation, technology orientation, cost orientation and resource orientation, on enterprise success. The hypotheses are tested in factor-analytic models, and structured equation models of the first and second order are discussed regarding content. As a result, production and costs orientation and market orientation most affect enterprise success. Therefore, the influence of management and business administration were found to be factors of success in different performance data. However, the results are to be interpreted in the scope of the formulated models.
The Strong Coupling Fixed-Point Revisited

subject: FOS: Physical sciences

description: In recent work we have shown that the Fermi liquid aspects of the strong coupling fixed point of the s-d and Anderson models can brought out more clearly by interpreting the fixed point as a renormalized Anderson model, characterized by a renormalized level $\tildeε_d$, resonance width, $\tildeΔ$, and interaction $\tilde U$, and a simple prescription for their calculation was given using the numerical renormalization group (NRG). These three parameters completely specify a renormalized perturbation theory (RPT) which leads to exact expressions for the low temperature behaviour. Using a combination of the two techniques, NRG to determine $\tildeε_d$, $\tildeΔ$, and $\tilde U$, and then substituting these in the RPT expressions gives a very efficient and accurate way of calculating the low temperature behaviour of the impurity as it avoids the necessity of subtracting out the conduction electron component. Here we extend this approach to an Anderson model in a magnetic field, so that $\tildeε_d$, $\tildeΔ$, and $\tilde U$ become dependent on the magnetic field. The de-renormalization of the renormalized quasiparticles can then be followed as the magnetic field strength is increased. Using these running coupling constants in a RPT calculation we derive an expression for the low temperature conductivity for arbitrary magnetic field strength.

description: In parallel with the rapid adoption of Artificial Intelligence (AI) empowered by advances in AI research, there have been growing awareness and concerns of data privacy. Recent significant developments in the data regulation landscape have prompted a seismic shift in interest towards privacy-preserving AI. This has contributed to the popularity of Federated Learning (FL), the leading paradigm for the training of machine learning models on data silos in a privacy-preserving manner. In this survey, we explore the domain of Personalized FL (PFL) to address the fundamental challenges of FL on heterogeneous data, a universal characteristic inherent in all real-world datasets. We analyze the key motivations for PFL and present a unique taxonomy of PFL techniques categorized according to the key challenges and personalization strategies in PFL. We highlight their key ideas, challenges and opportunities and envision promising future trajectories of research towards new PFL architectural design, realistic PFL benchmarking, and trustworthy PFL approaches.

description: A novel approach to the description of superconductors in thermal equilibrium is developed within a formally exact density-functional framework. The theory is formulated in terms of three ``densities'': the ordinary electron density, the superconducting order parameter, and the diagonal of the nuclear N-body density matrix. The electron density and the order parameter are determined by Kohn-Sham equations that resemble the Bogoliubov-de Gennes equations. The nuclear density matrix follows from a Schroedinger equation with an effective N-body interaction. These equations are coupled to each other via exchange-correlation potentials which are universal functionals of the three densities. Approximations of these exchange-correlation functionals are derived using the diagrammatic techniques of many-body perturbation theory. The bare Coulomb repulsion between the electrons and the electron-phonon interaction enter this perturbative treatment on the same footing. In this way, a truly ab-initio description is achieved which does not contain any empirical parameters.

description: In preparation for the IGM tomography study by Subaru Prime Focus Spectrograph (PFS) survey and other large future telescopes such as TMT/ELT/GMT, we present the results of our pilot study on Ly$α$ forest and IGM tomography statistics using the GADGET3-OSAKA cosmological smoothed particle hydrodynamical simulation. Our simulation includes models for star formation and supernova feedback, which enables more realistic cross-correlation studies between galaxies, neutral hydrogen (HI) and metals in circumgalactic and intergalactic medium. We create a light-cone data set at $z=2-3$ from our simulations and generate mock Ly$α$ forest data. As a first step, in this paper, we focus on the distribution of HI and galaxies, and present statistical results on 1D flux PDF, 1D power spectrum, flux contrast vs. impact parameter, HI$-$galaxy cross-correlations. Our results show overall agreement with current observational data, with some interesting discrepancies on small scales that are due to either feedback effects or varying observational conditions. Our simulation shows stronger HI absorption with decreasing transverse distance from galaxies. We find that the massive galaxies with $M_\star \ge 10^{10}\,M_\odot$ contribute strongly to the flux contrast signal, and that the lower-mass galaxies with $M_\star \sim 10^8-10^{10}\,M_\odot$ tend to dilute the flux contrast signal from massive galaxies. On large scales, the average flux contrast smoothly connects to the IGM level, supporting the concordance $Λ$ cold dark matter model. We also find an increase in the HI absorption toward the center of a protocluster.

description: We study the connection between charged lepton electric dipole moments, $d_l$ $(l=e,μ,τ)$, and seesaw neutrino mass generation in a simple two Higgs doublet extension of the Standard Model plus three right-handed neutrinos (RHN) $N_a$, $a=1,2,3$. For RHN with hierarchical masses and at least one with mass in the 10 TeV range we obtain the upper bounds of $|d_e|< 9\times 10^{-30}$ e-cm and $|d_μ|<2 \times 10^{-26}$ e-cm. Our scenario favors the normal mass hierarchy for the light neutrinos. We also calculated the cross section for $e^-e^- \ra W^- W^-$ in a high luminosity collider with constraints from neutrinoless double beta decay of nuclei included. Among the rare muon decay experiments we find that $μ\ra eγ$ is most sensitive and the upper limit is $<8\times 10^{-13}$.

description: This paper is the third of a series of three, and it is the continuation of math-ph/0412074 and math-ph/0412075. After reviewing the conformal spacetime structure, conformal maps are described in Minkowski spacetime as the twisted adjoint representation of the group Spin_+(2,4), acting on paravectors. Twistors are then presented via the paravector model of Clifford algebras and related to conformal maps in the Clifford algebra over the lorentzian R{4,1}$ spacetime. We construct twistors in Minkowski spacetime as algebraic spinors associated with the Dirac-Clifford algebra Cl(1,3)(C) using one lower spacetime dimension than standard Clifford algebra formulations, since for this purpose the Clifford algebra over R{4,1} is also used to describe conformal maps, instead of R{2,4}. Although some papers have already described twistors using the algebra Cl(1,3)(C), isomorphic to Cl(4,1), the present formulation sheds some new light on the use of the paravector model and generalizations.

Subjects: subject: 10104 Combinatorics and Discrete Mathematics (excl. Physical Combinatorics)

description: We study several problems in extremal combinatorics, random graphs, and asymptotic convex geometry. Extremal combinatorics is the area of mathematics studying the behavior of the \best" discrete structure among a family of structures with respect to certain parameter, whereas probabilistic combinatorics often study the \average"behavior shown by the most of the structures. Random graphs is one of the biggest fi?elds in probabilistic combinatorics. Asymptotic convex geometry, on the other hand, deals with geomteric problems on convex sets in \large" dimensional Euclidean space. In Chapter 2, we systematically study a natural problem in extremal graph theory, to minimize the number of edges in a graph with a ?fixed number of vertices, subject to a certain local condition: each vertex must be in a copy of a ?fixed graph H. We completely solve this problem when H is a clique, as well as more generally when H is any regular graph with degree at least about half its number of vertices. We alsocharacterize the extremal graphs when H is an Erdos-Renyi random graph. In Chapter 3, we consider two important questions in the well-studied theory of graphs that are F-saturated. We ?first resolve the most fundamental question ofminimizing the number of cliques of size r in a Ks-saturated graph for all sufficiently large numbers of vertices, con?rming a conjecture of Kritschgau, Methuku, Tait, and Timmons. We then make partial progress in the negative direction on a central and longstanding conjecture in graph saturation made by Tuza. In Chapter 4, we determine the maximum number of cliques of a fi?xed order in a graph with ?fixed number of edges and bounded maximum degree with complete characterization of extremal graphs, resolving a conjecture by Kirsch and Radcliffe. In Chapter 5, we generalize the notion of game chromatic number of a graphto hypergraphs. We analyze the game chromatic number of a random k-uniform hypergraph and prove upper and lower bounds that hold w.h.p. In Chapter 6, we study a question posed by Frieze in [67] related to the existenceof a patterned perfect matching in a randomly colored graph.In Chapter 7, we study the isomorphism problem for random hypergraphs. We show that it is polynomially time solvable for the binomial random k-uniform hypergraph Hn;p;k, for a wide range of p, and for random r-regular, k-uniform hypergraphs. Finally in Chapter 8, we study the expected volume of random polytopes generated by taking the convex hull of independent identically distributed points from a givendistribution.

description: A determination of the dynamical evolution of the asteroid belt is difficult because the asteroid belt has evolved since the time of asteroid formation through mechanisms that include: (1) catastrophic collisions, (2) rotational disruption, (3) chaotic orbital evolution and (4) orbital evolution driven by Yarkovsky radiation forces. The timescales of these loss mechanisms are uncertain and there is a need for more observational constraints. In the inner main belt, the mean size of the non-family asteroids increases with increasing inclination. Here, we use that observation to show that all inner main belt asteroids originate from either the known families or from ghost families, that is, old families with dispersed orbital elements. We estimate that the average age of the asteroids in the ghost families is a factor of 1/3 less than the Yarkovsky orbital evolution timescale. However, this orbital evolution timescale is a long-term average that must allow for the collisional evolution of the asteroids and for stochastic changes in their spin directions. By applying these constraints on the orbital evolution timescales to the evolution of the size-frequency distribution of the Vesta asteroid family, we estimate that the age of this family is greater than 1.3 $Gyr$ and could be comparable with the age of the solar system. By estimating the number of ghost families, we calculate that the number of asteroids that are the root sources of the meteorites and the near-Earth asteroids that originate from the inner main belt is about 20.

description: The density functional theory for superconductors developed in the preceding article [cond-mat/0408685] is applied to the calculation of superconducting properties of several elemental metals. In particular, we present results for the transition temperature, for the gap at zero temperature, and for thermodynamic properties like the specific heat. We obtain an unprecedented agreement with experimental results. Superconductors both with strong and weak electron-phonon coupling are equally well described. This demonstrates that, as far as conventional superconductivity is concerned, the first-principles prediction of superconducting properties is feasible.

Non-perturbative QCD effects at low Q^2 are separately treated for u and d valence quarks, and sea quarks. The improved model uses all inelastic charged lepton F_2 data (SLAC/BCDMS/NMC/HERA), and photoproduction data on proton and deuterium. In this way, we obtain an improved model which describes all inelastic scattering charged lepton data, JLAB resonance data, and neutrino data. This improved model is expected to be better for neutrino oscillation experiments at few GeV region.

Single-copy activation of Bell nonlocality via broadcasting of quantum states

description: Activation of Bell nonlocality refers to the phenomenon that some entangled mixed states that admit a local hidden variable model in the standard Bell scenario nevertheless reveal their nonlocal nature in more exotic measurement scenarios. We present such a scenario that involves broadcasting the local subsystems of a single-copy of a bipartite quantum state to multiple parties, and use the scenario to study the nonlocal properties of the two-qubit isotropic state: \begin{align} \nonumber ρ_α= α\,|Φ^+ \rangle\langle Φ^+|+(1-α)\frac{\mathbb{1}}{4}. \end{align} We present two main results, considering that Nature allows for (i) the most general no-signalling correlations, and (ii) the most general quantum correlations at the level of any hidden variable theory. We show that the state does not admit a local hidden variable description for $α>0.559$ and $α>\frac{1}{2}$, in cases (i) and (ii) respectively, which in both cases provides a device-independent certification of the entanglement of the state. These bounds are significantly lower than the previously best-known bound of $0.697$ for both Bell nonlocality and device-independent entanglement certification using a single copy of the state. Our results show that strong examples of non-classicality are possible with a small number of resources.

Assessing sensitivity to unmeasured confounding in observational studies : a bayesian approach
Creators: name: McCandless, Lawrence Cruikshank
Publisher: name: University of British Columbia
Year: 2009

description: Systematic error due to possible unmeasured confounding may weaken the validity of findings from observational studies investigating the effects of exposures on disease. Because study subjects are assigned to exposure levels in a non-random way, hidden differences between exposure groups may bias effect estimates in a way which is difficult to predict. A solution is to conduct a Bayesian sensitivity analysis (BSA) which incorporates uncertainty about unmeasured confounding into the analysis as prior distributions on bias parameters. Markov chain Monte Carlo techniques can then be used to summarize the posterior distribution of the exposure effect given the data and prior belief's about unmeasured confounding. We consider BSA in the context of logistic regression models for a binary exposure, binary outcome, binary unmeasured confounder and covariate vector. Because the resulting model is not identifiable, standard theory governing the large sample behaviour of posterior distributions cannot be applied, complicating an evaluation of the performance of BSA. However, using two simulation studies, we demonstrate that if the prior distribution for the analysis of datasets from a sequence of observational studies approximates the distribution from which study parameters arise, then the coverage probabilities of BSA 95% credible intervals will be approximately 95% when averaged over many studies. Moreover, we demonstrate that BSA credible intervals tends to yield greater coverages probabilities of the true exposure effect compared to methods which ignore unmeasured confouding. As an example, we investigate the effect of possible unmeasured confouding on risk of elevated triglyceride levels among HIV infected persons treated with protease inhibitors.

description: This paper addresses a reliable facility location problem in which the possibility of facility disruption is considered. There are two types of candidate sites which differ from the reliability aspects. A combination of cooperative and backup coverage concepts are considered. It is assumed that customers can be covered by a combination of reliable and unreliable emergency centers in their primal coverage. Backup coverage is also considered for demands in which primal coverage is provided by unreliable centers. The proposed model aims to minimize the total costs, including fixed and expected transportation costs. The nonlinear formulation is resulted and is linearized by the necessary constraints. In addition, the abovementioned problem is solved by the GAMS optimization software, using a number of generated examples in order to demonstrate the performance of the model.

We find a satisfactory agreement between theoretical predictions and experimental data. This supports the study of spin effects and transverse single spin asymmetries (SSA) within the same scheme. We then present results for SSA, generated by the so-called Sivers effect, in inclusive pion production in proton-proton collisions.

description: Netzwerke in Wireless Sensor Networkss (WSNs) oder Internet of Things (IoT) werden oft durch eine Mesh-Struktur ausgezeichnet. Dieses generelle Routing-Verfahren wird benötigt, um die räumliche Ausdehnung sowie die Ausfallsicherheit des Systems zu gewährleisten. Diese eingebrachte Redundanz bringt allerdings auch eine gewisse Komplexität in das Routing-Verfahren ein, welches von den typischerweise batteriebetriebenen Niedrigenergiegeräten bewältigt werden muss.Das Ziel dieser Arbeit ist die Definition, Messung und der Vergleich von Energieeffizienz in WSNs mit Routing Verfahren, welche speziell für die Anwendung in Netzwerken mit Niedrigenergiegeräten und verlustbehafteten Verbindungen ausgelegt sind. Der Fokus liegt dabei speziell auf multicastfähigen Routing Verfahren. Die Resultate und Metriken werden dabei anhand von physikalischer Hardware ausgewertet und aufgenommen,um eine Aussage über die Anwendbarkeit von Energieeffizienz-Metriken basierend auf Simulationen zu treffen. Die Ergebnisse der Arbeit zeigen, dass aufgrund von Hardwareeigenschaften eine Korrelation zwischen Hardware-unabhängigen Metriken und der tatsächlichen Energieeffizienz des Systems nicht immer gegeben ist und von gewissen Größen in Software und Hardware abhängig ist.
description: Networks in WSNs or the IoT rely heavily on mesh-routing in order to achieve their defining spatial distribution and a certain redundancy in the communication. This redundancy, though, introduces a non-trivial routing problem that needs to be handled by typically battery powered low power devices.The goal of this thesis is the definition, survey, measurement and comparison of energy efficiency in WSNs deploying multicast routing engines in networks defined by low-power devices and lossy connections.The results and metrics are thereby collected on real hardware, in order to show the applicability of simulation based energy efficiency metrics when comparing them to devices and networks confronted by real-world hardware behavior and influences. The results of this thesis show that with certain settings and configurations of the routing engine and the hardware itself, the correlation between metrics used in hardware-independent studies do not correlate with the actual energy efficiency of the real-world system.

description: Distributed Systems Infrastructure (DSI) is MongoDB's framework for running fully automated system performance tests in our Continuous Integration (CI) environment. To run in CI it needs to automate everything end-to-end: provisioning and deploying multi-node clusters, executing tests, tuning the system for repeatable results, and collecting and analyzing the results. Today DSI is MongoDB's most used and most useful performance testing tool. It runs almost 200 different benchmarks in daily CI, and we also use it for manual performance investigations. As we can alert the responsible engineer in a timely fashion, all but one of the major regressions were fixed before the 4.2.0 release. We are also able to catch net new improvements, of which DSI caught 17. We open sourced DSI in March 2020.

Charmless Final State Interaction in B-> pi pi decays

name: Brdnik, Anita Prapotnik

Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We estimate effects of the final state interactions in B -> pi pi decays coming from rescattering of pi pi via exchange of rho, sigma, f_0 mesons. Then we include the rho rho rescattering via exchange of pi, omega, a_1 mesons and finally we consider contributions of the a_1 pi rescattering via exchange of rho. The absorptive parts of amplitudes for these processes are determined. In the case of pi^+ pi^- decay mode, due to model uncertainties, the calculated contribution is |M_A| =< 1.7 x 10^-8 GeV. This produces a small relative strong phase for the tree and color-suppressed B -> pi pi amplitudes consistent with the result of a recent phenomenological analysis based on the BaBar and Belle results for the B -> pi pi branching ratios and CP asymmetries.

description: It is widely known that very small datasets produce overfitting in Deep Neural Networks (DNNs), i.e., the network becomes highly biased to the data it has been trained on. This issue is often alleviated using transfer learning, regularization techniques and/or data augmentation. This work presents a new approach, independent but complementary to the previous mentioned techniques, for improving the generalization of DNNs on very small datasets in which the involved classes share many visual features. The proposed methodology, called FuCiTNet (Fusion Class inherent Transformations Network), inspired by GANs, creates as many generators as classes in the problem. Each generator, $k$, learns the transformations that bring the input image into the k-class domain. We introduce a classification loss in the generators to drive the leaning of specific k-class transformations. Our experiments demonstrate that the proposed transformations improve the generalization of the classification model in three diverse datasets.
WWF Biodiversity Risk Filter Methodology Documentation

Publisher: name: Zenodo
Year: 2023

description: This document describes the underlying methodology of the Inform, Explore and Assess Modules that have already been integrated in the WWF BRF tool, including a description of the risk assessment framework, underlying structure, data and limitations. In addition, WWF and Climate & Company developed guidances that has not been included into the WWF BRF tool at this point: Guidance A, B and C. Guidance A and B, on the one hand, provide support for companies and financial institutions on collecting the required input data for the WWF BRF and WRF Assess Modules. Guidance A supports financial institutions with collecting location-specific proxy data on companies’ operational sites. Guidance B supports companies and financial institutions with collecting location-specific proxy data on supply chain sites. On the other hand, Guidance C provides support for financial institutions on how the location-specific output data from the WWF BRF and WRF Assess Modules can be further processed and aggregated to the company- and portfolio-level.

Returning radiation in strong gravity around black holes: Reverberation from the accretion disc

description: We study reflected X-ray emission that returns to the accretion disc in the strong gravitational fields around black holes using General Relativistic ray tracing and radiative transfer calculations. Reflected X-rays that are produced when the inner regions of the disc are illuminated by the corona are subject to strong gravitational light bending, causing up to 47 per cent of the reflected emission to be returned to the disc around a rapidly spinning black hole, depending upon the scale height of the corona. The iron K line is enhanced relative to the continuum by 25 per cent, and the Compton hump by up to a factor of three. Additional light travel time between primary and secondary reflections increases the reverberation time lag measured in the iron K band by 49 per cent, while the soft X-ray lag is increased by 25 per cent and the Compton hump response time is increased by 60 per cent. Measured samples of X-ray reverberation lags are shown to be consistent with X-rays returning to the accretion disc in strong gravity. Understanding the effects of returning radiation is important in interpreting reverberation observations to probe black holes. Reflected X-rays returning to the disc can be uniquely identified by blueshifted returning iron K line photons that are Compton scattered from the inner disc, producing excess, delayed emission in the 3.5-4.5keV energy range that will be detectable with forthcoming X-ray observatories, representing a unique test of General Relativity in the strong field limit.

Time-dependent local Green's operator and its applications to manganites
Creators: name: Aliaga, H.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: An algorithm is presented to calculate the electronic local time-dependent Green's operator for manganites-related hamiltonians. This algorithm is proved to scale with the number of states $N$ in the Hilbert-space to the 1.55 power, is able of parallel implementation, and outperforms computationally the Exact Diagonalization (ED) method for clusters larger than 64 sites (using parallelization). This method together with the Monte Carlo (MC) technique is used to derive new results for the manganites phase diagram for the spatial dimension D=3 and half-filling on a 12x12x12 cluster (3456 orbitals). We obtain as a function of an insulating parameter, the sequence of ground states given by: ferromagnetic (FM), antiferromagnetic AF-type A, AF-type CE, dimer and AF-type G, which are in remarkable agreement with experimental results.

description: The research starts from the necessity to create specific tools for evaluating the impacts of rural development policies on fragile areas. The objective of this study is to exploit a synthetic measure of marginality, obtained through a specific tool set by IRES Piemonte (Institute of Socio Economic Research) as a proxy of quality of life indicators. The aim of this tool is to evaluate the potential effects of the measures programmed in axes 3 and 4 of Rural Development Programmes, in terms of changes in quality of life in rural areas. In the evaluation field, this methodology is applicated for the first time to Piedmont’s Rural Development Programme.

description: CAP Pillar 2 policies and Rural Development Programmes (RDPs) reflect a broad range of governance styles and policy priorities, as well as significant devolution to regions and/or provinces within Member States. The processes supporting this new style of policymaking have become increasingly differentiated. The Europe 2020 document identifies significant “new challenges” facing the EU’s rural areas, notably climate change, sustainable water management and renewable energy generation. All of these “new challenges” impinge on EU rural development policies, and imply a need for significant shifts in priorities and actions. This paper draws from recent research carried out within the RuDI project, to analyse the capacity of the current Pillar 2 approach to meet these new challenges. The research notes a high and perhaps increasing level of bureaucratisation of EU rural development policy, but at the same time thr growing “territorial” nature of RDPs and the evolution of active partnerships at both strategic and local levels. Examples of innovative action within Estonia and the United Kingdom, as well as a brief budgetary analysis, enable a discussion of RDPs’ capacity to accommodate a new challenges agenda, and both positive and negative points are identified. The paper concludes by considering how changes to the Pillar 2 framework after 2013 could enhance its capacity to plan for, and execute, more ambitious responses.
