description: Different ways of implementing dimension-by-dimension CWENO reconstruction are discussed and the most efficient method is applied to develop a fourth order central scheme for multi-dimensional hyperbolic problems. Fourth order accuracy and shock capturing nature of the scheme are demonstrated in various nonlinear multi-dimensional problems. In order to show the overall performance of the present central scheme numerical errors and non-oscillatory behavior are compared with existing multi-dimensional CWENO based central schemes for various multi-dimensional problems. Moreover, the benefits of the present fourth order central scheme over third order implementation are shown by comparing the numerical dissipation and computational cost between the two.

LLAMA - A novel system for in-situ monitoring of optical parameters in liquid argon
Creators: name: Krause, Patrick

name: Laszlo Papp
name: Schönert, Stefan
Publisher: name: Zenodo
Year: 2020

description: Large volume liquid argon (LAr) detectors require a precise assessment of optical key parameters for both modeling and interpreting the data. These parameters include the light yield, the triplet lifetime, and in particular, the attenuation length at the 128 nm primary scintillation wavelength. A change in impurity concentrations within the LAr volume affects these values and therefore requires a dedicated monitoring system, especially for long-term measurements. The next-generation neutrinoless double beta decay experiment LEGEND employs the LAr technology as part of its active veto system. The LLAMA (LEGEND Liquid Argon Monitoring Apparatus) will reside permanently in the LAr volume of LEGEND-200, the first phase of LEGEND, measuring the aforementioned optical key parameters continuously. An overview of LLAMA as well as the first results will be shown. The work has been supported in part by the German Federal Ministry for Education and Research (BMBF) Verbundforschung.

description: In this paper, we study the effects of polynomial $f(R)$ model on the stability of homogeneous energy density in self-gravitating spherical stellar object. For this purpose, we construct couple of evolution equations which relate the Weyl tensor with matter parameters. We explore different factors responsible for density inhomogeneities with non-dissipative dust, isotropic as well as anisotropic fluids and dissipative dust cloud. We find that shear, pressure, dissipative parameters and $f(R)$ terms affect the existence of inhomogeneous energy density.

Measuring cross sections of neutrino-nucleus interactions with associated charged pions in the NOvA near detector
Creators: name: Sweeney, Cathal
Publisher: name: Zenodo
Year: 2020

description: Understanding neutrino-nucleus interactions is a key part of measuring oscillation parameters in a long-baseline experiment. The NOvA near detector is a liquid-scintillator-based tracking calorimeter located 1 Km from the target of the NuMI beam. This poster presents work from several ongoing analyses to measure cross sections of semi-inclusive processes either containing pions in the final state, or explicitly not containing pions in the final state, both of which require the ability to identify pions. The resulting measurements will allow a better understanding of systematic uncertainties in oscillation measurements at NOvA, as well as provide a method of testing models currently used in Monte Carlo neutrino event generators.

description: We report on a large improvement in the wetting of Al2O3 thin films grown by un-seeded atomic layer deposition on monolayer graphene, without creating point defects. This enhanced wetting is achieved by greatly increasing the nucleation density through the use of polar traps induced on the graphene surface by an underlying metallic substrate. The resulting Al2O3/graphene stack is then transferred to SiO2 by standard methods.

description: For a fixed graph H with t vertices, an H-factor of a graph G with n vertices, where t divides n, is a collection of vertex disjoint (not necessarily induced) copies of H in G covering all vertices of G. We prove that for a fixed tree T on t vertices and ϵ>0, the random graph Gn,p, with n a multiple of t, with high probability contains a family of edge-disjoint T-factors covering all but an ϵ-fraction of its edges, as long as ϵ4np≫log2n. Assuming stronger divisibility conditions, the edge probability can be taken down to p>Clognn. A similar packing result is proved also for pseudo-random graphs, defined in terms of their degrees and co-degrees.
Single pion production is neutrino interactions
Creators: name: Kabirnezhad, Minoo
Publisher: name: Zenodo
Year: 2020

description: This work represents an extension of the [MK model][1]. The MK model provides a full kinematic description of single pion production in the neutrino-nucleon interactions, including resonant and nonresonant interactions in the helicity basis, in order to study the interference effect. The resonant interactions of MK model are described by RS model. In the new approach, we use Rarita-Swinger formalism to describe four important resonances ($P_{33}(1232), P_{11}(1440), D_{13}(1520)$, $S_{11}(1535)$). We also fit the vector form-factor of the MK model to the electron scattering data and estimate 1$sigma$ error. At low $Q^2$ we can relate the neutrino-nucleon cross-section, which has pure axial contribution at Q2= 0, to pion-nucleon cross-section. Therefore we use pion scattering data to fit the axial form factor of the MK model. [1]: https://inspirehep.net/literature/1634864

description: Since its inception in the early 1970s, Saemaul Undong(SMU) has played a pivotal role in bridging the economic growth gap between rural and urban Korea that eventually brought progress to the entire nation. SMU, a Korean community development movement, is not only recognized by the global community but also inscribed on the UNESCO Memory of the World Register. This study seeks to investigate success drivers of SMU’s promotion processes from a role of government perspective. The research also intends to discover and propose implications of rural development processes in less developed countries via SMU of the 1970s from the viewpoint of the development state theory of Asian countries by Chalmers Johnson and Alice Amsden. Effectual execution of SMU is derivative of harmonic balance between mobilization and participation of the actors involved; the focus of this paper is rather on the analysis of the role of government centering around institutional mechanism and political and administrative efforts of the state. The proposed Globalization Strategy of SMU negates the traditional ODA model of material and human resource-based aid for rural development; rather it suggests emphasis on the role of government to establish an effective and sustainable administrative system governed by policy makers in order to achieve villager participatory rural development.

For such $γ$, we obtain a closed form expression for the Bergman kernel, $\mathbb{B}_γ$. With these formulas, we make new observations relating to the Lu Qi-Keng problem and analyze the boundary behavior of $\mathbb{B}_γ(z,z)$.

Within this model, we answer precisely a question of Alizadeh et al concerning the minimum number of probes required to reconstruct the entire ordering of a given clone library with high probability. We also examine the related problem of determining the least number of probes required to construct a 'spine' for the library. We give a fairly precise characterization for this number."

All-flavor search for high-energy neutrinos in correlation with very-high-energy gamma-rays in ANTARES data
Creators: name: Molla, Marta Colomer
Publisher: name: Zenodo
Year: 2020

description: The first gamma-ray burst (GRB) detections at very-high energies (sub-TeV gamma-rays) have been announced recently: GRB190114C, observed by MAGIC, GRB180720B and GRB190829A, both detected by the H.E.S.S. telescopes. A dedicated search for all-flavor high-energy neutrinos in correlation with the gamma-ray emission has been performed using ANTARES data. The search covers both the prompt and afterglow phases. This contribution presents the results of this study and discusses the associated astrophysical constraints on the neutrino spectral fluence and the total energy radiated in high-energy neutrinos (TeV-PeV range).

description: Some anisotropic Bianchi V dark energy models are investigated in a scale invariant theory of gravity. We consider two non interacting fluids such as dark energy and a bulk viscous fluid. Dark energy pressure is considered to be anisotropic in different spatial directions. A dynamically evolving pressure anisotropy is obtained from the models. The models favour phantom behaviour. It is observed that, in presence of dark energy, bulk viscosity has no appreciable affect on the cosmic dynamics.

description: The proposed Short-Baseline Neutrino (SBN) physics program at Fermilab will deliver a rich and compelling physics opportunity, including the ability to resolve a class of experimental anomalies in neutrino physics. The far detector of the SBN program is the ICARUS-T600. The ICARUS-T600(760 tons) is the biggest LArTPC detector. The ICARUS-T600 was designed for the low background, deep underground conditions of LNGS laboratory. A major upgrade of the ICARUS detector was performed at CERN in order to allow it to cope with a high cosmic background is the upgrade of the light collection system.. We will discuss about the upgrade and the performance study of the new light detection system of the ICARUS-T600 detector at the SBN Program. Installation and commissioning of the detector components along with the Photo-Multiplier Tube (PMT) system have been completed and currently the apparatus is ready to taking data.

description: We consider the problem of k-colouring a random r-uniform hypergraph with n vertices and cn edges, where k, r, c   remain constant as n→∞.

We give a complete generalisation of this result to random uniform hypergraphs.
Vertexing and Tracking Software at Belle II

Year: 2014
Subjects: subject: Instrumentation and Detectors (physics.ins-det)

description: Belle II is a $B$ factory experiment aiming to start physics data taking in 2017. It is currently being set up at the SuperKEKB accelerator at the KEK facility in Tsukuba (Japan), an asymmetric $e^+e^-$ collider which aims to achieve an unprecedented instantaneous luminosity of $8\cdot10^{35} \textrm{Hz}/\textrm{cm}^2$. This forty-fold increase over predecessor experiments is achieved by employing a novel nano-beam scheme. Originally developed for the now-defunct SuperB experiment, this scheme allows a significant increase in luminosity at only modest increases of beam currents. Challenges for the vertex detector result from increased data and background rates. At full luminosity, physics data will be recorded at a rate of $30\,\textrm{kHz}$. The radiation-hard DEPFET-sensors of the innermost layer of the vertex detector will be read out employing a novel data-reduction scheme using selective detector read out based on online reconstruction of event data. Belle II uses a software framework in which data handling is unified between various data processing modules. In this way, tasks can be divided flexibly and the same software framework can be used for a diversity of tasks ranging from the high-level trigger to final processing of plots for publications. Tracking and vertexing modules are currently under development and we will discuss their features.

description: Many body quantum eigenstates of generic Hamiltonians at finite energy density typically satisfy "volume law" of entanglement entropy: the von Neumann entanglement entropy and the Renyi entropies for a subregion scale in proportion to its volume. Here we provide a connection between the volume law and the sign structure of eigenstates. In particular, we ask the question: can a positive wavefunction support a volume law entanglement? Remarkably, we find that a typical random positive wavefunction, exhibits a constant law for Renyi entanglement entropies $S_n$ for $n>1$, despite arbitrary large amplitude fluctuations. We also provide evidence that the modulus of the finite energy density eigenstates of generic local Hamiltonians show similar behavior.

(1554–1578). Neste âmbito, número de combatentes e não combatentes, nacionalidades,
composição profissional, social e etária, são algumas das esferas de trabalho que,
passados 445 anos, continuam em aberto.
Imediatamente após a batalha, em delegação de poderes por parte do Cardel Rei D.
Henrique (1512–1580), foi a Ordem da Santíssima Trindade que assumiu as rédeas do
complexo processo de negociação e redenção de cativos do Norte de África. Listagens
inéditas e riquíssimas em contéudo foram analisadas no decorrer do Projeto exploratório
Moving City tendo em vista, especificamente, gerar um conhecimento mais claro dos
efetivos que compunham o exército, tanto da parte civil como dos homens da "profissão
das armas".
Neste sentido, com o objetivo de ultrapassar as lacunas identificadas, considerámos
fundamental cruzar os dados retirados da documentação trinitária com aqueles que estão
dispersos pelas múltiplas fontes não trinitárias, isto é, as diversas crónicas, relatos e
publicações que foram sendo redigidas desde o final do século XVI. Enquanto bolseiro
de investigação, esta tarefa foi por mim assumida. O 'catálogo' que agora apresento é o
resultado de, sensivelmente, 18 meses de trabalho, com o objetivo de identificar as
principais obras que contribuíram para a identificação dos falecidos e desaparecidos em
combate, mas também daqueles que foram cativos e resgatados.
A identificação de todos estes indivíduos será fundamental para conhecer os efetivos,
tanto civis como militares, que compunham o exército – uma verdadeira "cidade em
movimento".
Coherent Elastic Neutrino Nucleus Scattering as a Probe to Study Reactor-Antineutrino Fluxes and Spectra

description: Since their first observation in 1956, reactor antineutrinos have almost been exclusively measured through the Inverse Beta Decay (IBD) process, allowing to achieve a precise understanding of their fluxes and spectra above 1.8 MeV. The Coherent Elastic Neutrino Nucleus Scattering (CEvNS) process, recently observed for the first time by the COHERENT collaboration, offers a new channel for the detection of reactor antineutrinos with the possibility to access for the first time the low energy part of the spectrum. This poster reports on a sensitivity study which aims at estimating the potential of ultra-low threshold bolometric detectors to measure the low energy part of a reactor antineutrino spectrum as typically emitted by commercial pressurized water reactors. Motivated by recent findings from the latest generation of IBD experiments (Daya Bay, RENO and Double Chooz) the sensitivity of CEvNS to a potential distortion of the reactor antineutrino spectrum is also presented.

The effect of parameters in the subordinators on the subordinated process is discussed. By suitable variable substitutions and Laplace transform technique, the corresponding fractional Fokker-Planck-type equations are derived. We also compute their mean square displacements in a free force field. By choosing suitable ranges of parameters, the resulting subordinated processes may be subdiffusive, normal diffusive or superdiffusive.

Impact of Light Concentrators on Antineutrino Detection in WATCHMAN
Creators: name: Kunkle, Paige
Publisher: name: Zenodo
Year: 2020

description: There is great interest within the nonproliferation community to establish remote monitoring of nuclear reactors at distances greater than several tens of kilometers. Large-scale neutrino detectors could be designed for exactly this purpose. The WATer CHerenkov Monitor for Anti-Neutrinos (WATCHMAN) is proposed as the first such detector for the new Advanced Instrumentation Testbed (AIT) at Boulby Underground Laboratory, UK. Here we study the development of light concentrators instrumented around photomultiplier tubes in WATCHMAN. The theory of non-imaging optics as applied to light concentration was used to establish the ideal curvature for such a detector, which approaches the thermodynamic limit of light collection. Monte Carlo simulations for a range of light concentrator shapes, sizes, and materials were performed to determine the optimized concentrator design for a realistic reactor monitoring scenario. The details of these light collection studies and the overall impact on reactor antineutrino detection sensitivity are discussed.

description: We have investigated the thermally induced proton/deuteron exchange in mixed amorphous H$_2$O:D$_2$O ices by monitoring the change in intensity of characteristic vibrational bending modes of H$_2$O, HDO, and D$_2$O with time and as function of temperature. The experiments have been performed using an ultra-high vacuum setup equipped with an infrared spectrometer that is used to investigate the spectral evolution of homogeneously mixed ice upon co-deposition in thin films, for temperatures in the 90 to 140 K domain. With this non-energetic detection method we find a significantly lower activation energy for H/D exchange -- $3840 \pm 125$ K -- than previously reported. Very likely this is due to the amorphous nature of the interstellar ice analogues involved. This provides reactive timescales ($τ<10^4$ years at $T$ $>70$ K) fast enough for the process to be important in interstellar environments. Consequently, an astronomical detection of D$_2$O will be even more challenging because of its potential to react with H$_2$O to form HDO. Furthermore, additional experiments, along with previous studies, show that proton/deuteron swapping also occurs in ice mixtures of water with other hydrogen bonded molecules, in particular on the OH and NH moieties. We conclude that H/D exchange in ices is a more general process that should be incorporated into ice models that are applied to protoplanetary disks or to simulate the warming up of cometary ices in their passage of the perihelion, to examine the extent of its influence on the final deuteron over hydrogen ratio.

description: This paper aims to draw some implications from the German tax reduction program for agricultural holdings by examining its institutional configuration and operating system. In order to be recognized as an agricultural holding under the tax law, several steps need to be taken in the registration process. A newly founded agricultural holding should join agricultural social insurances and register its establishment with the tax office. The registered business entity then can receive various benefits such as tax reduction. A significant implication of the German system concerning the registration of an agricultural holding under the tax law is that it not only clarifies the requirements of a legitimate agricultural holding but also provides the foundation for the efficient tax policies such as Earned Income Tax Credit(EITC).

On utility maximization under convex portfolio constraints

Subjects: subject: 19999 Mathematical Sciences not elsewhere classified
subject: FOS: Mathematics

description: We consider a utility-maximization problem in a general semimartingale financial model, subject to constraints on the number of shares held in each risky asset. These constraints are modeled by predictable convex-set-valued processes whose values do not necessarily contain the origin; that is, it may be inadmissible for an investor to hold no risky investment at all. Such a setup subsumes the classical constrained utility-maximization problem, as well as the problem where illiquid assets or a random endowment are present.
Our main result establishes the existence of optimal trading strategies in such models under no smoothness requirements on the utility function. The result also shows that, up to attainment, the dual optimization problem can be posed over a set of countably-additive probability measures, thus eschewing the need for the usual finitely-additive enlargement.

description: We study the nanoscale behaviour of the density of a simple fluid in the vicinity of an equilibrium contact line for a wide range of Young contact angles between 40 and 135 degrees. Cuts of the density profile at various positions along the contact line are presented, unravelling the apparent step-wise increase of the film height profile observed in contour plots of the density. The density profile is employed to compute the normal pressure acting on the substrate along the contact line. We observe that for the full range of contact angles, the maximal normal pressure cannot solely be predicted by the curvature of the adsorption film height, but is instead softened -- likely by the width of the liquid-vapour interface. Somewhat surprisingly however, the adsorption film height profile can be predicted to a very good accuracy by the Derjaguin-Frumkin disjoining pressure obtained from planar computations, as was first shown in [Nold et al., Phys. Fluids, 26, 072001, 2014] for contact angles less than 90 degrees, a result which here we show to be valid for the full range of contact angles. This suggests that while two-dimensional effects cannot be neglected for the computation of the normal pressure distribution along the substrate, one-dimensional planar computations of the Derjaguin-Frumkin disjoining pressure are sufficient to accurately predict the adsorption height profile.

description: We study the evolution of passive scalars in both rigid and moving slab-like domains, in both horizontally periodic and infinite contexts. The scalar is required to satisfy Robin-type boundary conditions corresponding to Newton's law of cooling, which lead to nontrivial equilibrium configurations. We study the equilibration rate of the passive scalar in terms of the parameters in the boundary condition and the equilibration rates of the background velocity field and moving domain.

subject: FTA domestic countermeasures

description: In this study we conduct an ex post economic assessment of domestic measures related to Korea-Chile FTA as seven years have passed since the free trade agreement was in effect in 2004. The production-increase and cost-reduction effects are evaluated by constructing a regional and periodical panel model using the investment and financial results of the domestic FTA measures for the fruit industry. In addition, the effects of the investment and financial support programs on the farmers' selling prices of fruits are estimated using inverse demand functions. We calculate the effects of the quality improvements as well as the products diversification on the increasing added values. According to our empirical results, the investment and financial support for the domestic fruit industry against Korea-Chile FTA is shown to have partly contributed to increases in production, reductions of production costs, increases in added values of final products, and reductions of distribution costs.

description: Radio frequency (RF) plays a critical role in many military systems such as navigation, radar, and communication systems. Common DoD use cases include satellite communication (SATCOM), radio, radar, or tactical data links that help coordinate troop movements, signal position info about a target, or help maintain communication between aircraft and drones. A recent report indicated the DoD is susceptible to potential RF attack vectors, indicating the need to better understand and prevent vulnerabilities. In this RF 101 guide from the Carnegie Mellon University Software Engineering Institute (SEI), we explore some of the fundamentals of radio frequency communication, delve into the generalities of protocols and device interactions, discuss common RF tools, and uncover ways malicious actors can attack systems. We summarize the basics of RF technology and the risks associated with it and discuss how the SEI is helping to secure wireless communications.
Meson effective mass in the isospin medium in hard-wall AdS/QCD model

description: We study a mass splitting of light vector, axial-vector and pseudoscalar mesons in isospin medium in the framework of hard-wall model. We write an effective mass definition for the interacting gauge fields and scalar field introduced in gauge field theory in the bulk of AdS space-time. Relying on holographic duality we obtain a formula for the effective mass of a boundary meson in terms of derivative operator over the extra bulk coordinate. The effective mass found in this way coincides with the one obtained from finding of poles of the two-point correlation function. In order to avoid introducing distinguished infrared boundaries in the quantisation formula for the different mesons from the same isotriplet we introduce extra action terms at this boundary, which reduces distinguished values of this boundary to the same value. Profile function solutions and effective mass expressions were found for the in-medium $ρ$, $a_1$ and $π$ mesons.

Subjects: subject: 19999 Mathematical Sciences not elsewhere classified

description: This paper studies rates of decay to equilibrium for the Becker-Döring equations with subcritical initial data. In particular, polynomial rates of decay are established when initial perturbations of equilibrium have polynomial moments. This is proved by using new dissipation estimates in polynomially weighted ℓ1spaces, operator decomposition techniques from kinetic theory, and interpolation estimates from the study of travelling waves.
System of on-Axis Neutrino Detector
Creators: name: Andriaseta Sitraka
Publisher: name: Zenodo
Year: 2020

description: The Deep Underground Neutrino Experiment (DUNE) will be a long-baseline neutrino experiment with a Near and a Far detector. In the near detector complex, an on-axis spectrometer system called SAND (System of on-Axis Neutrino Detector) centered by a 3D projection scintillator tracker (3DST) is proposed. It will be located downstream of a liquid-argon TPC and a magnetized tracker with gaseous argon target. The system consists of 3DST, surrounded by a light density tracker, an ECAL and a superconducting magnet. The SAND will provide comprehensive measurements on a fully active scintillator target allowing beam monitoring on a timely basis and constraints on the A-dependence of neutrino interaction models. In addition, with the capability of neutron detection, we can fully reconstruct the neutrino energy, which provides new ways to analyze neutrino interactions. This poster will show different physics studies in SAND and preliminary results from 3DST prototypes.

description: The document focuses on optimizing the Water-Energy-Food-Ecosystems (WEFE) Nexus in the Mediterranean basin, recognizing the interconnectedness of these components and the need for joint planning, international cooperation, and transparent decision-making to achieve sustainable development goals. The WEFE Nexus approach is particularly relevant in the Mediterranean region due to socioeconomic considerations, climate variability, population growth, and developmental pressures. The document addresses various challenges, including over-tourism, water pricing's impact on local agriculture, energy production's effects on ecosystems, and provides policy recommendations to tackle these issues. It underscores the significance of collaborative efforts and adopting a Nexus approach to effectively manage resources and promote sustainable development in the Mediterranean. To enhance coordination, efficiency, and sustainability across the WEFE Nexus in the Mediterranean, the document proposes several recommendations: Implement tourism development policies that address over-tourism, biodiversity decline, and zoning regulations. Focus on the Water Node of the Nexus by improving water distribution systems, addressing water contamination and wastewater management, and promoting stakeholder collaboration. Ensure policy coherence by considering the WEFE Nexus interlinkages in sectoral policies and promoting capacity building activities to work towards meeting UN Sustainable Development Goals. Mitigate energy consumption and urban pressures by adopting nature-based solutions in urban planning, designing energy-efficient buildings and infrastructures (e.g., green roofs), and embracing renewable energy technologies to boost agricultural production and preserve ecosystems. The document represents a collaborative effort among six projects: SIGMA Nexus, AWESOME, NEXUS-NESS, NEXOGENESIS, GoNEXUS, and REXUS.

description: Relaxor ferroelectric perovskites are highly polarizable and can exhibit giant coupling between elastic strain and an applied electric field. Here, we report an in situ extended X-ray absorption fine structure (EXAFS) study of a PbZn1/3Nb2/3O3 (PZN) single crystal as a function of the electric field. We show that the strong dipoles in the NbO6 octahedra bonds are aligned along the four \textless{} 011 \textgreater{} directions close to the orientation of the electric field, while a small reversible polar shift occurs for Zn in the direction of the electric field, i.e., positive or negative. This reversible Zn-O polar shift is proposed to play an important role in both the "easy" switching of the ferroelectric polarization and the giant piezoelectric effect in PZN.

description: The tree-level two-point amplitudes for the transitions $jf \to j^{\, \prime} f^{\, \prime}$, where $f$ is a fermion and $j$ is a generalized current, in a constant uniform magnetic field of an arbitrary strength and in charged fermion plasma, for the $jff$ interaction vertices of the scalar, pseudoscalar, vector and axial-vector types have been calculated. The generalized current $j$ could mean the field operator of a boson, or a current consisting of fermions, e.g. the neutrino current. The particular cases of a very strong magnetic field, and of the coherent scattering off the real fermions without change of their states (the "forward" scattering) have been analysed. The contribution of the neutrino photoproduction process, $γe\to e ν\bar ν$, to the neutrino emissivity has been calculated with taking account of a possible resonance on the virtual electron.
