description: The pure self-gravitating system in this paper refers to a multi-body gaseous system where the self-gravity plays a dominant role and the intermolecular interactions can be neglected. Therefore its total mass must be much more than a limit mass, the minimum mass of the system exhibiting long-range nature. Thee method to estimate the limit mass is then proposed. The nonequlibrium stationary state in the system is identical to the Tsallis equilibrium state, at which the Tsallis entropy approaches to its maximum. On basis of this idea, we introduce a new concept of the temperature whose expression includes the gravitational potential and therefore we call it gravitational temperature. Accordingly, the gravitational thermal capacity is also introduced and it can be used to verify the thermodynamic stability of the astrophysical systems.

description: У статті проаналізовано актуальні питання правового регулювання волонтерської діяльності у контексті надання волонтерської допомоги Збройним Силам України. Визначено основні проблеми та недоліки існуючої правової бази, зокрема, невизначеність правового статусу волонтерів, які активно залучаються до підтримки військових дій. З’ясовано, що значна частина нормативно-правових актів потребує перегляду та адаптації до умов воєнного стану.

Обґрунтовано необхідність розробки нових законодавчих ініціатив, які б вдосконалили правове регулювання надання волонтерської допомоги Збройним Силам України та забезпечували належний правовий захист учасникам волонтерських організацій і окремим волонтерам. Розглянуто питання одноразової грошової допомоги та відшкодування волонтерам, які постраждали або загинули під час виконання своїх обов’язків, а також обов'язки держави щодо надання гарантій безпеки та соціального захисту волонтерам, які надають волонтерську допомогу Збройним Силам України.

Доведено, що наявні закони не в повній мірі відповідають потребам та викликам сучасності, що призводить до правових колізій та ускладнень надання волонтерами волонтерської допомоги Збройним Силам України. Сформовані висновки вказують на критичну потребу в удосконаленні законодавчої бази, спрямованої на забезпечення ефективної взаємодії між волонтерами, державними органами та військовими підрозділами.

Подальше законодавче регулювання має включати в себе чіткість визначення обов’язків та прав волонтерів, механізми їх захисту, а також особливості взаємодії волонтерських організацій та волонтерів з органами державної влади та органами військового управління. Це стане основою для забезпечення належної правової підтримки та безпеки волонтерів, залучених до допомоги Збройним Силам України, що є важливим для підтримки національної безпеки в умовах збройного конфлікту.
Convergence of the two-phase Stefan problem to the one-phase problem

description: Abstract: "We study the limit of the one-dimensional Stefan problem as the diffusivity coefficient of the solid phase approaches zero. We derive a weak formulation of the equilibrium condition for the resulting one-phase problem that allows jumps of the temperature accross [sic] the interface. The weak formulation consists of a regularity condition that only enforces the usual equilibrium condition to hold from the liquid phase. At the end we briefly discuss the radial problem in higher space dimensions. The main tool in order to prove the convergence are uniform bounds on the total variation of the free boundary that are derived using a regularized problem, where the equilibrium condition is substituted by a dynamical condition."

description: The average-distance problem is to find the best way to approximate (or represent) a given measure μ   on RdRd by a one-dimensional object. In the penalized form the problem can be stated as follows: given a finite, compactly supported, positive Borel measure μ, minimize
E(Σ)=∫Rdd(x,Σ)dμ(x)+λH1(Σ)

among connected closed sets, Σ  , where λ>0λ>0, d(x,Σ)d(x,Σ) is the distance from x to the set Σ  , and H1H1 is the one-dimensional Hausdorff measure. Here we provide, for anyd⩾2d⩾2, an example of a measure μ   with smooth density, and convex, compact support, such that the global minimizer of the functional is a rectifiable curve which is not C1C1. We also provide a similar example for the constrained form of the average-distance problem.

description: Silicene and germanene derivatives constructed from periodic dumbbell units play a crucial role in multilayers of these honeycomb structures. Using first-principles calculations based on density functional theory, here we investigate the dumbbell formation mechanisms and energetics of Group IV atoms adsorbed on graphene, silicene, germanene and stanene monolayer honeycomb structures. The stabilities of the binding structures are further confirmed by performing ab-initio molecular dynamics calculations at elevated temperatures, except for stanene which is subject to structural instability upon the adsorption of adatoms. Depending on the row number of the adatoms and substrates we find three types of binding structures, which lead to significant changes in the electronic, magnetic, and optical properties of substrates. In particular, Si, Ge and Sn adatoms adsorbed on silicene and germanene form dumbbell structures. Furthermore, dumbbell structures occur not only on single layer, monatomic honeycomb structures, but also on their compounds like SiC and SiGe. We show that the energy barrier to the migration of a dumbbell structure is low due to the concerted action of atoms. This renders dumbbells rather mobile on substrates to construct new single and multilayer Si and Ge phases.

description: We study the cover time of a random graph chosen uniformly at random from the set of graphs with vertex set [n] and degree sequence d = (di) n i=1. In a previous work [1], the asymptotic cover time was obtained under a number of assumptions on d, the most significant being that di ≥ 3 for all i. Here we replace this assumption by di ≥ 2. As a corollary, we establish the asymptotic cover time for the 2-core of the emerging giant component of G(n, p).

description: LEGEND searches for lepton number violation in neutrinoless double beta (0νββ) decay using $^{76}$Ge-enriched high-purity germanium (HPGe) detectors immersed in liquid argon. The first stage, LEGEND-200, will operate 200 kg of detectors, a significant fraction of which are the new large Inverted Coaxial Point Contact (ICPC) detectors currently under production. An extensive characterization campaign to determine the basic operational parameters of the newly produced detectors is performed in vacuum cryostats at two underground sites in order to reduce the internal creation of cosmogenic radionuclides. Other dedicated scanning setups are used to obtain a detailed understanding of alpha and beta surface events on the p+ and n+ contacts which are projected to be the dominant backgrounds for the 0νββ decay search. This poster will present the production experience of the new ICPC detectors, the ongoing characterization campaigns, and the projected detector performances based on recent measurements.

description: Although the population of science teachers in the US lacks diversity, the technology used to teach science should be diverse and culturally connected. Culturally relevant frameworks for science call for science teaching to be situated in meaningful contexts. This study calls for the integration of CRP and situated cognition perspectives as a means of designing pedagogically effective virtual reality. This mixed-methods study explored N = 444 students changes in attitudes after experiencing VR lessons on an attitude survey and qualitative short answers. We found that all students who used the VR improved their attitudes towards science. We also found that students who used the CRP designed VR developed a conscious and politically aware application of science. The results suggest that educational technology should carefully consider how using CRP-based approaches can have both cognitive and cultural implications of students’ learning.

It is shown that, these algorithms give rise to a discrete semigroup theory that parallels the continuous problem. In particular, the discrete Stefan problem gives rise to nonlinear semigroups in both the discrete L┬╣ and H[superscript -1] spaces."

The theory is based on the notion of configurational forces in conjunction with a mechanical version of the second law. Kinking and curving of the crack are allowed under the assumption that the crack will propagate in a direction that maximizes the rate at which it dissipates energy."

description: Cadmium Zinc Telluride and Cadmium Telluride are the detector materials of choice for the detection of X-rays in the X-ray energy band E >= 5keV with excellent spatial and spectral resolution and without cryogenic cooling. Owing to recent breakthroughs in grazing incidence mirror technology, next-generation hard X-ray telescopes will achieve angular resolution between 5 and 10 arc seconds - about an order of magnitude better than that of the NuSTAR hard X-ray telescope. As a consequence, the next generation of X-ray telescopes will require pixelated X-ray detectors with pixels on a grid with a lattice constant of <= 250um. Additional detector requirements include a low energy threshold of less than 5keV and an energy resolution of less than one keV. The science drivers for a high angular-resolution X-ray mission include studies and measurements of black hole spins, the cosmic evolution of super-massive black holes, active galactic nuclei feedback, and the behaviour of matter at very high densities. In this contribution, we report on our R&D studies with the goal to optimise small-pixel Cadmium Zinc Telluride and Cadmium Telluride detectors.

Double-Differential $\nu_\mu$ Charged Current Quasi-Elastic Cross Section on Plastic Scintillator in Muon Momentum from MINERvA
Creators: name: Olivier, Andrew
name: Silva, Mateus Carneiro Da
Publisher: name: Zenodo
Year: 2020

description: Long baseline neutrino oscilllation experiments rely on charged-current quasi-elastic (CCQE) neutrino interactions to reconstruct the characteristic energy dependence of oscillation probabilities. The MINERvA experiment at Fermilab tests models for processes that obscure neutrino energy and interaction channel reconstruction on a variety of nuclear targets. MINERvA's first CCQE measurement from the 6 GeV flux peak Medium Energy (ME) era tests model predictions for CCQE-like interactions on CH at the high end of the planned DUNE flux. This 2D test of neutrino interaction generators hints at data-model disagreements in interactions that strike groups of correlated nucleons. Increases in the NuMI beam's intensity since MINERvA's previous CCQE results enable measurements over a greater region of phase space in $p_T^\mu$, $p_{||}^\mu$, and $Q^2$.

description: While there is wide agreement that physical activity is an important component of a healthy lifestyle, it is unclear how many people adhere to public health recommendations on physical activity. The Physical Activity Guidelines (PAG), published by the CDC, provides guidelines to American adults, but it is difficult to assess compliance with these guidelines. The PAG further complicates adherence assessment by recommending activity to occur in at least 10 min bouts. To better understand the measurement capabilities of various instruments to quantify activity, and to propose an approach to evaluate activity relative to the PAG, researchers at Iowa State University administered the Physical Activity Measurement Survey (PAMS) to over 1000 participants in four different Iowa counties. In this paper, we develop a two-part Bayesian measurement error model and apply it to the PAMS data in order to assess compliance with the PAG in the Iowa adult population. The model accurately accounts for the 10 min bout requirement put forth in the PAG. The measurement error model corrects biased estimates and accounts for day-to-day variation in activity. The model is also applied to the nationally representative National Health and Nutrition Examination Survey.

description: Refactoring is the process of improving the design of existing code by changing its internal structure without affecting its external behaviour, with the main aims of improving the quality of software product. Therefore, there is a belief that refactoring improves quality factors such as understandability, flexibility, and reusability. However, there is limited empirical evidence to support such assumptions. The objective of this study is to validate/invalidate the claims that refactoring improves software quality. The impact of selected refactoring techniques was assessed using both external and internal measures. Ten refactoring techniques were evaluated through experiments to assess external measures: Resource Utilization, Time Behaviour, Changeability and Analysability which are ISO external quality factors and five internal measures: Maintainability Index, Cyclomatic Complexity, Depth of Inheritance, Class Coupling and Lines of Code. The result of external measures did not show any improvements in code quality after the refactoring treatment. However, from internal measures, maintainability index indicated an improvement in code quality of refactored code than non-refactored code and other internal measures did not indicate any positive effect on refactored code

description: This paper establishes the consistency of a family of graph-cut-based algorithms for clustering of data clouds. We consider point clouds obtained as samples of a ground-truth measure. We investigate approaches to clustering based on minimizing objective functionals defined on proximity graphs of the given sample. Our focus is on functionals based on graph cuts like the Cheeger and ratio cuts. We show that minimizers of the these cuts converge as the sample size increases to a minimizer of a corresponding continuum cut (which partitions the ground truth measure). Moreover, we obtain sharp conditions on how the connectivity radius can be scaled with respect to the number of sample points for the consistency to hold. We provide results for two-way and for multiway cuts. Furthermore we provide numerical experiments that illustrate the results and explore the optimality of scaling in dimension two.

description: Joint modelling of longitudinal and time-to-event data is usually described by a joint model which uses shared or correlated latent effects to capture associations between the two processes. Under this framework, the joint distribution of the two processes can be derived straightforwardly by assuming conditional independence given the random effects. Alternative approaches to induce interdependency into sub-models have also been considered in the literature and one such approach is using copulas to introduce non-linear correlation between the marginal distributions of the longitudinal and time-to-event processes. The multivariate Gaussian copula joint model has been proposed in the literature to fit joint data by applying a Monte Carlo expectation-maximisation algorithm. In this paper, we propose an exact likelihood estimation approach to replace the more computationally expensive Monte Carlo expectation-maximisation algorithm and we consider results based on using both the multivariate Gaussian and t copula functions. We also provide a straightforward way to compute dynamic predictions of survival probabilities, showing that our proposed model is comparable in prediction performance to the shared random effects joint model.
Viscous-poroelastic interaction as mechanism to create adhesion in frogs' toe pads

description: The toe pads of frogs consist of soft hexagonal structures and a viscous liquid contained between and within the hexagonal structures. It has been hypothesized that this configuration creates adhesion by allowing for long range capillary forces, or alternatively, by allowing for exit of the liquid and thus improving contact of the toe pad. In this work we suggest interaction between viscosity and elasticity as a mechanism to create temporary adhesion, even in the absence of capillary effects or van der Waals forces. We initially illustrate this concept experimentally by a simplified configuration consisting of two surfaces connected by a liquid bridge and elastic springs. We then utilize poroelastic mixture theory and model frog's toe pads as an elastic porous medium, immersed within a viscous liquid and pressed against a rigid rough surface. The flow between the surface and the toe pad is modeled by the lubrication approximation. Inertia is neglected and analysis of the elastic-viscous dynamics yields a governing partial differential equation describing the flow and stress within the porous medium. Several solutions of the governing equation are presented and show a temporary adhesion due to stress created at the contact surface between the solids. This work thus may explain how some frogs (such as the torrent frog) maintain adhesion underwater and the reason for the periodic repositioning of frogs' toe pads during adhesion to surfaces.

description: There are a lot of policy instruments of green growth which is defined as economic growth that creates new growth power and job opportunities while minimizing environmental pollution and greenhouse gases. Green growth policies in agriculture and rural districts are classified into six policies: climate policy, energy policy, policy for creation of green space, resource management policy, green industry policy, and green technology policy. This paper analyzes the priority of policy instruments of green growth using the analytic hierarchy process which determines priorities of policy programs by applying the criteria for policy evaluation based on survey of expertise. The result shows that efficiency is the most important policy evaluation criterion and so improving energy use efficiency, establishing an efficient R&D system and promoting bio-industry are very crucial policy measures.

description: The LiquidO detection technique falls on the light confinement near its creation point by using an opaque liquid scintillator and on the light collection by a dense array of fibres. This technique enables highly efficient particle identification with the consequent event-by-event topological discrimination power, including positron, electron and gamma events. With the potential background rejection capability and the possibility of loading dopants at high concentrations, since transparency in no longer required, LiquidO opens up the possibility of a large number of new physics measurements. The poster will present the neutrino detection potential at the MeV-scale, with LiquidO projects ranging from understanding the nature of the neutrino itself, to addressing some key neutrino sources such as the earth, the Sun and supernovae core-collapse processes.

Year: 2022

description: Metadata is at the heart of DOIs and open scholarly infrastructure. At DataCite, our metadata schema defines what metadata properties can be included through DOI registration. The schema currently includes just six required properties—identifier (the DOI), creator, title, publication year, publisher, and resource type—along with 14 recommended and optional properties.

On the one hand, requiring only six metadata properties keeps the schema flexible and makes it easy to get started with DOI registration. At the same time, we want to encourage all DataCite Metadata Schema users to go beyond the mandatory properties and to share rich metadata that includes all available information about a given resource. This is especially important for metadata properties that are essential for discoverability—such as description and subject—and building connections between PIDs—including identifiers for related resources, people, and organizations. Keeping metadata up-to-date is also critical to ensure that the “persistent” part of persistent identifiers lives up to its full potential.

description: Current global constraints in neutrino mixing parameters translate to lax PMNS unitarity relations. In this work, we explore the lack of non-unitarity in the neutrino mixing matrix via the astrophysical neutrino flavor content in both standard paradigms, as well as those involving sterile neutrinos. Astrophysical neutrino flavour composition is a sensitive tool to probe both non-unitarity and the presence of sterile neutrinos over many mass scales, and is a core focus for future high-energy neutrino telescopes. We develop new techniques, including the neutrino flavor tetrahedron, to explore the effects of non-unitary mixing, as well as the significant impact sterile neutrinos have on astrophysical neutrino composition.
Semiclassical momentum representation in quantum cosmology

description: It is well-known that the standard WKB approximation fails to provide semiclassical solutions in the vicinity of turning points. However, turning points arise in many cosmological scenarios. In a previous work, we obtained a new class of semiclassical solutions of the Wheeler-deWitt equation using the conjugate momentum to the geometric variable. We present here a detailed study of their main properties. We carefully compare them to usual WKB solutions and turning point resolutions using Airy functions. We show that the momentum representation possesses many advantages that are absent in other apporaches. In particular, this framework has a key application in tackling the problem of time. It allows us to use curvature as a time variable, and control the corresponding domain of validity, i.e. under which conditions it provides a good clock. We consider several applications, and in particular show how this allows us to obtain semiclassical solutions of the Wheeler-DeWitt equation parametrized by York time.

description: Random forest is a popular prediction approach for handling high dimensional covariates. However, it often becomes infeasible to interpret the obtained high dimensional and non-parametric model. Aiming for an interpretable predictive model, we develop a forward variable selection method using the continuous ranked probability score (CRPS) as the loss function. eOur stepwise procedure selects at each step a variable that minimizes the CRPS risk and a stopping criterion for selection is designed based on an estimation of the CRPS risk difference of two consecutive steps. We provide mathematical motivation for our method by proving that in a population sense, the method attains the optimal set. In a simulation study, we compare the performance of our method with an existing variable selection method, for different sample sizes and correlation strength of covariates. Our method is observed to have a much lower false positive rate. We also demonstrate an application of our method to statistical post-processing of daily maximum temperature forecasts in the Netherlands. Our method selects about 10% covariates while retaining the same predictive power.

description: The KamLAND-Zen program has recently set the worlds most stringent limit on neutrinoless double beta decay (0νββ), being the first experiment excluding a half-life less than 10$^{26}$ years at the 90% C.L. The next push will be to upgrade the detector hardware, increase the amount of dissolved xenon gas, and update the readout system in order to probe the full inverted hierarchy region. This is KamLAND2-Zen. This poster elaborates on the status of the upgrade with specific emphasis on the streaming readout system, which aims to utilize a powerful RF-ADC and FGPA system on a chip, the Xilinx Zynq Ultrascale+ RFSoC.

description: The feasibility of Rutherfordium IP measurements with the electron-impact source VADIS has been studied
 theoretically by estimation of adsorption properties and first experiments of ion source efficiency in function
 of mean electron energy.
 • IPs of noble gases could be derived within an error of 0.1 V following an extrapolation method.
 • Adsorption properties suggest, that temperatures above nominal conditions are necessary.
 • Further R&D is needed, which might include the partial redesign of the source.

description: Neutrinos play a key role in supernova explosions. When a massive star explodes, most of the gravitational binding energy released by the collapse of the core is carried away by neutrinos. In order to understand the mechanism of the supernova explosion and subsequent evolution of massive stars, we are going to discuss the neutrino transport appropriately to find the angular moment equations, also we will derive the radiative hydrodynamic equations for a couple system of neutrino radiation and matter both in the general relativistic framework. We obtained the neutrino transport equation and also derive the conservation of mass. The obtained equations are used to obtain the numerical solutions of supernova explosions and, at the end, we discuss about chirality of neutrinos and the helical effects that it induce.
BITS-Tree-An Efficient Data Structure for Segment Storage and Query Processing

description: In this paper, a new and novel data structure is proposed to dynamically insert and delete segments. Unlike the standard segment trees[3], the proposed data structure permits insertion of a segment with interval range beyond the interval range of the existing tree, which is the interval between minimum and maximum values of the end points of all the segments. Moreover, the number of nodes in the proposed tree is lesser as compared to the dynamic version of the standard segment trees, and is able to answer both stabbing and range queries practically much faster compared to the standard segment trees.

Conductivity of a Weyl semimetal with donor and acceptor impurities

subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We study transport in a Weyl semimetal with donor and acceptor impurities. At sufficiently high temperatures transport is dominated by electron-electron interactions, while the low-temperature resistivity comes from the scattering of quasiparticles on screened impurities. Using the diagrammatic technique, we calculate the conductivity $σ(T,ω,n_A,n_D)$ in the impurities-dominated regime as a function of temperature $T$, frequency $ω$, and the concentrations $n_A$ and $n_D$ of donors and acceptors and discuss the crossover behaviour between the regimes of low and high temperatures and impurity concentrations. In a sufficiently compensated material [$|n_A-n_D|\ll(n_A+n_D)$] with a small effective fine structure constant $α$, $σ(ω,T)\propto T^2/(T^{-2}-iω\cdot\text{const})$ in a wide interval of temperatures. For very low temperatures or in the case of an uncompensated material the transport is effectively metallic. We discuss experimental conditions necessary for realising each regime.

Subjects: subject: Flavour physics
subject: B physics
subject: Rare decays

subject: LHCb

description: Diese Arbeit präsentiert Suchen nach den rein leptonischen Zerfällen Bs0 → e+e- und B0 → e+e-, ebenso wie den leptonfamilienzahlverletzenden Zerfällen B+ → K+ e+ μ-. Da diese Zerfälle im Standardmodell selten oder verboten sind ermöglichen sie Nulltests des Standardmodells. Außerdem ermöglichen Messungen dieser Kanäle es Modellen von Physik jenseits des Standardmodells Einschränkungen aufzuerlegen. Die Suche nach den Zerfällen Bs0 → e+e- und B0 → e+e- nutzt Daten, welche vom LHCb Experiment in den Jahren 2011, 2012, 2015 und 2016 aufgezeichnet wurden und stellt die erste Suche am LHC nach diesen Zerfällen dar. Die bestimmten oberen Ausschlussgrenzen auf die Verzweigungsverhältnisse von Bs0 → e+e- und B0 → e+e- liegen in der Größenordnung O(10-8), was die vorhergegangenen Ausschlussgrenzen um einen Faktor 30 verbessert. Die Suche nach den leptonfamilienzahlverletzenden Zerfällen B+ → K+ e+ μ- nutzt den kompletten LHCb Datensatz, was obigen Datensätzen die Daten aus den Jahren 2017 und 2018 hinzufügt und so die Menge der B Mesonen im analysierten Datensatz effektiv verdoppelt. Da diese Analyse noch nicht veröffentlicht wurde, wird der Status der Analyse zum Zeitpunkt der Abfassung dieses Textes präsentiert.
description: In this thesis searches for the purely leptonic decays Bs0 → e+e- and B0 → e+e- as well as the lepton-flavour violating decays B+ → K+ e+ μ- are presented. As these decays are rare or forbidden in the Standard Model, these searches allow for null tests of the Standard Model. Measurements of these decays also allow to place constraints on scenarios of physics beyond the Standard Model. The search for the decays Bs0 → e+e- and B0 → e+e- uses data collected by the LHCb experiment in the years 2011, 2012,2015 and 2016, it is the first search for these decays at the LHC. Upper limits on the brnaching fractions of Bs0 → e+e- and B0 → e+e- are set at the order of O(10-8), improving the previous limits by a factor of 30. The search for the lepton-flavour violating decays B+ → K+ e+ μ- uses the full LHCb dataset, adding to the above the data collected in 2017 and 2018, effectively doubling the amount of B mesons in
Convolutional Neural Network Applied to BiPo Discrimination at SoLid

description: The BiPo-214 decay is a significant background to the antineutrino reconstruction in the SoLid detector. It has a very similar time and spatial signature as of the product of the inverse beta decay. SoLid has developed a unique technique to separate scintillation signals of neutron captured on Lithium-6 from the Po-214 alpha. The current Pulse Shape Discrimination technique is based on a ratio of charge integration window. Using a 1-dimensional convolutional network to fully characterise the shape of the waveform, we demonstrated a factor of two to three improvement in discrimination power over the current technique.
SBC-CEvNS

Publisher: name: Zenodo
Year: 2020

description: The SBC collaboration is developing liquid argon filled scintillating bubble chambers with projected sensitivity to coherent elastic neutrino nucleus scattering (CE$\nu$NS) from reactor neutrinos. Nuclear recoil induced bubbles are detected by cameras and piezoelectric acoustic sensors; scintillation photons from recoil events and backgrounds, shifted to 175 nm by xenon doping, are detected by an array of silicon photomultipliers. An initial 10-kg device is under construction at Fermilab to demonstrate effectively complete insensitivity to electron recoil backgrounds with nuclear recoil thresholds down to 100 eV. Follow-on devices will search for GeV-scale WIMPs down to the solar neutrino limit (SBC-SNOLAB), and attempt a first observation of CE$\nu$NS for reactor neutrinos (SBC-CE$\nu$NS). SBC-CE$\nu$NS may be able to constrain non-standard interactions, the weak mixing angle at low energies, sterile neutrino oscillations, and neutrino magnetic moments.
