description: A combined experimental and theoretical investigation of time- and alignment-dependent propagation of light in an ultracold atomic gas of atomic $^{85}$Rb is reported. Coherences among the scattering amplitudes for light scattering off excited hyperfine levels produce strong variations of the light polarization in the vicinity of atomic resonance. Measurements are in excellent agreement with Monte-Carlo simulations of the multiple scattering process.
Developing Wire-Cell techniques to improve a high efficiency high purity neutrino selection in the MicroBooNE LArTPC
Creators: name: Cooper-Troendle, London
Publisher: name: Zenodo
Year: 2020

description: The MicroBooNE Liquid Argon Time Projection Chamber promises high precision particle reconstruction and neutrino selection. However, as a surface detector, the abundance of cosmic rays creates a significant source of background. To preserve the high-quality selection promised by this technology, multiple novel reconstruction techniques have been developed to remove background sources. First, a flash-charge matching algorithm simultaneously matches numerous cosmic ray charge-clusters with their non-beam-coincident flashes. Additionally, a pair of light mismatch taggers identify incorrect flash-charge pairs based on the predicted vs measured flash as well as the cluster location relative to the detector boundary. Finally, stopped and throughgoing muon taggers remove muons that originate outside the detector based on their boundary intersections and directionality, as measured by their charge deposition profile. Together, these algorithms allow MicroBooNE to improve the neutrino selection purity from 0.005% to 86% while maintaining an efficiency of 86%.

description: This paper investigates the existence of neighborhood effects in farm income in rural Korea. A farm-level income survey data set combined with the data on regional characteristics is used to identify and estimate the neighborhood effects. It is shown that the neighborhood effects exist for farm agricultural income, off-farm income, and overall farm income. That is, the effects are identified for every major component of farm income. It is estimated that the multipliers including the feedback effects of income change are 1.081, 1.119 and 1.145 for agricultural income, off-farm income, and overall farm income, respectively. Hence, the neighborhood effects are the largest for off-farm income. Moreover, we identify and estimate the contributions of various individual farm characteristics, regional characteristics and neighborhood characteristics incorporating the feedback effects existing among farms.

description: Abstract: "We have recently introduced a method of variation of boundaries for the solution of diffraction problems. This method, which is based on a theorem of analyticity of the electromagnetic field with respect to variations of the interfaces, has been successfully applied in problems of diffraction of light by perfectly conducting gratings. In this paper we continue our investigation of diffraction problems. Using our previous results on analytic dependence with respect to the grating groove-depth, we present a new numerical algorithm which applies to dielectric gratings. We also incorporate Pade╠ü approximation in our numerics. This addition enlarges the domain of applicability of our methods, and it results in computer codes which can predict more accurately the response of diffraction gratings in the resonance region. In many cases, results are obtained which are several orders of magnitude more accurate than those given by other methods available at present, such as the integral or differential formalisms. We present a variety of numerical applications, including examples for several types of grating profiles and for wavelengths of light ranging from microwaves to ultraviolet, and we compare our results with experimental data. We also use Pade╠ü approximants to gain insight on the analytic structure and the spectrum of singularities of the fields as functions of the groove-depth. Finally, we discuss some connections between Pade╠ü approximation and another summation mechanism, enhanced convergence, which we introduced earlier. It is argued that, provided certain numerical difficulties can be overcome, the performance of our algorithms could be further improved by a combination of these summation methods."

description: We present analytic force-free solutions modeling rotating stars and black holes immersed in the magnetic field of a thin disk that terminates at an inner radius. The solutions are exact in flat spacetime and approximate in Kerr spacetime. The compact object produces a conical jet whose properties carry information about its nature. For example, the jet from a star is surrounded by a current sheet, while that of a black hole is smooth. We compute an effective resistance in each case and compare to the canonical values used in circuit models of energy extraction. These solutions illustrate all of the basic features of the Blandford-Znajek process for energy extraction and jet formation in a clean setting.

description: In Measure for Measure (MM), Isabella is taught to trick her male tormentor by feigning “a plausible obedience” (III.1.227), this instruction offers a useful lens through which to examine female characters’ negotiation/evasion of, conversational and societal norms of truthfulness both in MM and All’s Well That Ends Well (AW).           
From Lakoff (1973) to more recent studies (Erman 1992; Crawford 1995; Nevalainen 2000; 2002) gender has been considered an important variable in linguistics. There are observable, gender-specific differences in female-talk and male-talk in early modern texts.
Quantitative data from the pragma-stylistic analysis of deception in MM and AW indicates that women prefer ORVD strategies (off-record verbal deception; Beville 2022) while their male counterparts privilege blatant (on-record) lying. The present study aims to reveal and account for Shakespeare’s female characters’ divergent pragmatic strategies in the selected problem comedies, in the light of genre and gender conventions, in order to understand how Shakespeare’s women perform pseudo-cooperation within the comedies.

description: We use a volume-limited sample of quasars in the Sloan Digital Sky Survey (SDSS) DR7 quasar catalog to identify quasar groups and address their statistical significance. This quasar sample has a uniform selection function on the sky and nearly a maximum possible contiguous volume that can be drawn from the DR7 catalog. Quasar groups are identified by using the Friend-of-Friend algorithm with a set of fixed comoving linking lengths. We find that the richness distribution of the richest 100 quasar groups or the size distribution of the largest 100 groups are statistically equivalent with those of randomly-distributed points with the same number density and sky coverage when groups are identified with the linking length of 70 h-1Mpc. It is shown that the large-scale structures like the huge Large Quasar Group (U1.27) reported by Clowes et al. (2013) can be found with high probability even if quasars have no physical clustering, and does not challenge the initially homogeneous cosmological models. Our results are statistically more reliable than those of Nadathur (2013), where the test was made only for the largest quasar group. It is shown that the linking length should be smaller than 50 h-1Mpc in order for the quasar groups identified in the DR7 catalog not to be dominated by associations of quasars grouped by chance. We present 20 richest quasar groups identified with the linking length of 70 h-1Mpc for further analyses.

description: The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment designed to determine neutrino mass hierarchy, measure oscillation parameters and investigate solar neutrinos, supernova neutrinos and geoneutrinos, etc. The JUNO central detector (CD) contains 20 ktons of liquid scintillator with an acrylic sphere (35.4m inner diameter). Our baseline requirement of surface dusts from LS related systems is less than $0.1 mg/m^2$ for reactor neutrino analysis. In order to achieve this goal, four methods, including conductivity monitoring, light absorption spectra comparison, suspension particulate counting and ICP-MS measurement, are applied to monitor cleanliness levels. Multiple cleaning protocols are developed and verified to clean surface of acrylic, stainless steel and Teflon. The poster presents details of evaluation methods and cleaning protocols. The total signals rate contribution from surface cleanliness is less than 0.32 Hz in the fiducial volume (17.2m radius).

Exact solutions of the wave patterns are derived. The bifurcation diagram describing the transition between the immobile and self-propelling modes of camphor objects is derived semi-analytically. The bifurcation is of a pitchfork type which is consistent with earlier theoretical work in which natural boundary conditions have been considered.

Search for dark matter annihilation in the center of the Earth with 8 years of IceCube data
Creators: name: Renzi, Giovanni
Publisher: name: Zenodo
Year: 2020

description: Dark matter particles in the galactic halo can scatter off particles in celestial bodies such as stars or planets, lose energy and become gravitationally trapped. In this process, an accumulation of dark matter in the center of celestial bodies is expected, for example, at the center of the Earth. If dark matter self-annihilates into Standard Model particles, the end products of these annihilations include neutrinos. The IceCube Neutrino Observatory at the geographic South Pole can detect the resulting flux of neutrinos originating from dark matter annihilation in the center of the Earth. A search for this signal has been performed using 8 years of IceCube data and probing different annihilation channels. Here the new analysis is presented, showing significant sensitivity improvements with respect to the previous analyses from IceCube and other experiments.

description: We study the interaction of feedback from active galactic nuclei (AGN) and a multi-phase interstellar medium (ISM), in simulations including explicit stellar feedback, multi-phase cooling, accretion-disk winds, and Compton heating. We examine radii ~0.1-100 pc around a black hole (BH), where the accretion rate onto the BH is determined and where AGN-powered winds and radiation couple to the ISM. We conclude: (1) The BH accretion rate is determined by exchange of angular momentum between gas and stars in gravitational instabilities. This produces accretion rates ~0.03-1 Msun/yr, sufficient to power luminous AGN. (2) The gas disk in the galactic nucleus undergoes an initial burst of star formation followed by several Myrs where stellar feedback suppresses the star formation rate (SFR). (3) AGN winds injected at small radii with momentum fluxes ~L/c couple efficiently to the ISM and have dramatic effects on ISM properties within ~100 pc. AGN winds suppress the nuclear SFR by factors ~10-30 and BH accretion rate by factors ~3-30. They increase the outflow rate from the nucleus by factors ~10, consistent with observational evidence for galaxy-scale AGN-driven outflows. (4) With AGN feedback, the predicted column density distribution to the BH is consistent with observations. Absent AGN feedback, the BH is isotropically obscured and there are not enough optically-thin sightlines to explain Type-I AGN. A 'torus-like' geometry arises self-consistently as AGN feedback evacuates gas in polar regions.

Subjects: subject: feminist theology, theology of time, Christian feminism, the meaning of death, feminist eschatology, linear time concept, Process Theology.

description: The feminist theological literature highlights certain weaknesses in the traditional (Western) Christian understanding of eschatology, death and the concept of time. Many feminist theologians reject the linear time concept and the idea of final, fixed eschatology in which death is an enemy to be conquered and flourishing is postponed and reserved to another time and space. However, an alternative convincing vision for a concept of time in which eschatology and death have a place and meaning that is congruent with the feminist concerns and priorities is yet to be developed. My thesis aims to explore and suggest a workable concept of time from a feminist theological perspective with a reference to feminist eschatology and the role and meaning of death.

description: Free electrons can possess an intrinsic orbital angular momentum, similar to those in an electron cloud, upon free-space propagation. The wavefront corresponding to the electron's wavefunction forms a helical structure with a number of twists given by the \emph{angular speed}. Beams with a high number of twists are of particular interest because they carry a high magnetic moment about the propagation axis. Among several different techniques, electron holography seems to be a promising approach to shape a \emph{conventional} electron beam into a helical form with large values of angular momentum. Here, we propose and manufacture a nano-fabricated phase hologram for generating a beam of this kind with an orbital angular momentum up to 200$\hbar$. Based on a novel technique the value of orbital angular momentum of the generated beam are measured, then compared with simulations. Our work, apart from the technological achievements, may lead to a way of generating electron beams with a high quanta of magnetic moment along the propagation direction, and thus may be used in the study of the magnetic properties of materials and for manipulating nano-particles.

description: Spin freezing in the $A$-site spinel FeAl$_2$O$_4$ which is a spin liquid candidate is studied using remnant magnetization and nonlinear magnetic susceptibility and isofield cooling and heating protocols. The remnant magnetization behavior of FeAl$_2$O$_4$ differs significantly from that of a canonical spin glass which is also supported by analysis of the nonlinear magnetic susceptibility term $χ_3 (T)$. Through the power-law analysis of $χ_3 (T)$, a spin-freezing temperature, $T_g$ = 11.4$\pm$0.9~K and critical exponent, $γ$ = 1.48$\pm$0.59 are obtained. Cole-Cole analysis of magnetic susceptibility shows the presence of broad spin relaxation times in FeAl$_2$O$_4$, however, the irreversible dc susceptibility plot discourages an interpretation based on conventional spin glass features. The magnetization measured using the cooling-and-heating-in-unequal-fields protocol brings more insight to the magnetic nature of this frustrated magnet and reveals unconventional glassy behaviour. Combining our results, we arrive at the conclusion that the present sample of FeAl$_2$O$_4$ consists of a majority spin liquid phase with "glassy" regions embedded.

Novel ion trap design concept as a LAr purity monitor
Creators: name: Soderberg, Mitchell

Publisher: name: Zenodo
Year: 2020

description: Liquid Argon Time Projection Chambers (LArTPCs) are precision particle detectors whose performance depends on the non-attenuation of ionization electrons produced by the charged particles that cross their volume, which must drift up to several meters before being collected. For this to happen, the LAr used as active volume must be extremely pure of electronegative impurities that could absorb the ionization electrons. Thus, it is fundamental to monitor the LAr purity at all times during detector operation. This work presents a new design concept for a technology to monitor LAr purity that consists of trapping ions within a volume of the LArTPC and estimating LAr purity based on the time the population of ions remains trapped. Early results of a deterministic simulation of the physical behavior of barium ions confined by a RF trap submersed in LAr are presented. We explore in which conditions such ions remain stably trapped.

description: Abstract: "We determine the asymptotic behavior of the system of Cahn-Hilliard/Euler's equations that control the dynamics inside the thin boundary layer separating two inviscid, incompressible, and nearly immiscible fluids. This model was proposed recently in order to replace the classical moving boundary model of two immiscible fluids, separated by the interface with the surface tension. We formally verify that these two problems are related. Using the method of matched asymptotic expansions, we show that when the width of the interface and the miscibility of the fluids converge to zero, then the system of Cahn-Hillard/Euler's equations converges asymptotically to the classical moving boundary problem. In addition, we analyze for the different timescales the behavior of the mixture inside the boundary layer."

After all these years since its discovery, this is very likely to be the first correct translation of the inscription and hence the first actual decipherment, and if so it gives us more information about the Thracian language than any other Thracian inscription found so far, enabling one to get a better sense of Thracian's actual place among the Indo-European languages.
description: There are a few typos in this version.

The actual form Herodiade was the basis for the argument that Arada is not likely to derive from Herodiade, phonologically speaking. In this version of the manuscript, "the Latvian verb Zelt which meant to bloom, flourish..." was intended to be "The Latvian verb Zelt which means to bloom, flourish". "Meant" was simply a typo of one letter from my fingers, should have been "means".

description: We study the radial evolution of intermittency of density fluctuations in the fast solar wind. The study is performed analyzing the plasma density measurements provided by Helios 2 in the inner heliosphere between $0.3$ and $0.9$ AU. The analysis is carried out by means of a complete set of diagnostic tools, including the flatness factor at different time scales to estimate intermittency, the Kolmogorov-Smirnov test to estimate the degree of intermittency, and the Fourier transform to estimate the power spectral densities of these fluctuations. Density fluctuations within fast wind are rather intermittent and their level of intermittency, together with the amplitude of intermittent events, decreases with distance from the Sun, at odds with intermittency of both magnetic field and all the other plasma parameters. Furthermore, the intermittent events are strongly correlated, exhibiting temporal clustering. This indicates that the mechanism underlying their generation departs from a time-varying Poisson process. A remarkable, qualitative similarity with the behavior of plasma density fluctuations obtained from a numerical study of the nonlinear evolution of parametric instability in the solar wind supports the idea that this mechanism has an important role in governing density fluctuations in the inner heliosphere.
Application of Convolutional Neural Networks to Reconstruct GeV-Scale IceCube Neutrino Events

description: The IceCube Neutrino Observatory instruments a cubic kilometer of ice at the South Pole to detect atmospheric and astrophysical neutrinos. IceCube consists of a 3D array of 5160 optical modules which detect light from relativistic charged particles resulting from neutrino interactions in the ice. This can be used to reconstruct the neutrino's energy and direction, but becomes particularly challenging at energies less than 100 GeV since IceCube is optimized for TeV-PeV scale neutrinos. These GeV-scale neutrinos are important for studying neutrino properties, such as the oscillation parameters. My work uses convolutional neural networks to reconstruct the energy and direction of these GeV-scale neutrinos in the IceCube detector.

description: Recently, a growing interest has been addressed to the electrical properties of bacteriorhodopsin (bR), a protein belonging to the transmembrane protein family. To take into account the structure-dependent nature of the current, in a previous set of papers we suggested a mechanism of sequential tunneling among neighbouring amino acids. As a matter of fact, it is well accepted that, when irradiated with green light, bR undergoes a conformational change at a molecular level. Thus, the role played by the protein tertiary-structure in modeling the charge transfer cannot be neglected. The aim of this paper is to go beyond previous models, in the framework of a new branch of electronics, we called proteotronics, which exploits the ability to use proteins as reliable, well understood materials, for the development of novel bioelectronic devices. In particular, the present approach assumes that the conformational change is not the unique transformation that the protein undergoes when irradiated by light. Instead, the light can also promote a free-energy increase of the protein state that, in turn, should modify its internal degree of connectivity, here described by the change in the value of an interaction radius associated with the physical interactions among amino acids. The implemented model enables us to achieve a better agreement between theory and experiments in the region of a low applied bias by preserving the level of agreement at high values of applied bias. Furthermore, results provide new insights on the mechanisms responsible for bR photoresponse.

description: We study polychromatic Ramsey theory with a focus on colourings of [ω 2]2. We show that in the absence of GCH there is a wide range of possibilities. In particular each of the following is consistent relative to the consistency of ZFC: (1) 2 ω = ω 2 and ω2→poly(α)2ℵ0−bdd for everyα <ω 2; (2) 2 ω = ω 2 and ω2↛poly(ω1)22−bdd.
Constraints on Neutrino Emission from Nearby Galaxies Using the 2MASS Redshift Survey and IceCube
Creators: name: Étienne Bourbeau
Publisher: name: Zenodo
Year: 2020

description: The result of two searches for correlations between neutrinos and the matter in the Local Universe (z<0.03) is presented : A template analysis, which looks for neutrino emission patterns coming from collisions between ultra-high-energy cosmic rays (UHECR) and local galaxy matter, and a multiplet analysis, which looks for neutrino produced in low-luminosity sources within local galaxies. Both searches use the 2MASS Redshift Survey (2MRS) catalog as a proxy for the distribution of matter in the Local Universe, while the neutrino data taken from a seven-year sample developed for time-integrated searches of neutrino sources in the IceCube Neutrino Observatory.

description: A new translation of the Thracian inscription on the Ezerovo gold ring found in 1912. After all these years since its discovery, this is very likely to be the first correct translation of the inscription and hence the first actual decipherment, and if so it gives us more information about the Thracian language than any other Thracian inscription found so far, enabling one to get a better sense of Thracian's actual place among the Indo-European languages.

THE CONCEPT AND FORMATION OF HANDWRITING: WHAT HANDWRITING ANALYSIS ENTAILS AND HOW IT IS DEVELOPED
Creators: name: Arislanova, Shaxnoza
Publisher: name: Zenodo
Year: 2024

description: Since the dawn of civilization, handwriting has been one of the most important forms of communication. However, since handwriting varies from person to person, author identification has become a promising application of pattern recognition to determine the actual author of a handwritten document. The article discusses the signs and methods studied and applied in domestic forensic handwriting analysis. An overview of sources on forensic handwriting analysis is given for mentioning and describing general and specific signs in writing, its study and the possibility of using it in individual methods of forensic handwriting examination.

Study of the atmospheric neutrino background for Supernova Relic Neutrino search
Creators: name: Sakai, Seiya
Publisher: name: Zenodo
Year: 2020

description: Neutrinos which were emitted from all past core-collapse supernovae form the integrated flux, called supernova relic neutrinos (SRNs). Detecting SRNs would enable us to study the supernova mechanism as well as the star formation history; however, they have never been discovered even in the most sensitive searches at Super-Kamiokande (SK). SK is a 50 kton water Cherenkov detector and has a plan to dissolve gadolinium to enhance the sensitivity to SRNs, which is termed the SK-Gd phase. In the SRN search, atmospheric neutrino interactions are one of the serious backgrounds and currently the largest uncertainty comes from de-excitation gamma-rays emitted from neutron-oxygen reactions. In this poster, I compared the number of gamma-rays emitted from neutron-oxygen reactions, neutron multiplicity and neutron energy distribution by using various neutron models installed in GEANT4-based simulation.
Feasibility Analysis on Geothermal Heat Storage Capacity and Recovery of Alberta’s.pdf

Subjects: Environmental rehabilitation and restoration

description: The province of Alberta is home to one of the World’s largest strategic sedimentary basins. The Oil and Gas industry has been Alberta’s major source of economic prosperity for more than half a century. There are plenty of related environmental concerns with the oil and gas operations. The Earth’s thermal energy potential known as Geothermal is one the most reliable sustainable energy sources with the least negative environmental impacts. In this capstone project, a feasibility analysis with numerical model was performed for heat storage and recovery, to create synthetic geothermal reservoirs in Alberta’s cold shallow formations. Additionally, an analytical model was created to recover sustainable heat for space heating applications from hot deep deposited formations using the decommissioned wells. The objective of this study is to provide a sustainable solution to meet some of the Alberta’s growing energy mix demand for the future while lowering the GHG emissions and negative environmental impacts of the abandoned oil and gas wells.

description: Fifth version with important updates: I have an etymology for Roli- now (I did not have an etymology for that component in my previous version) which is of a very high certainty (99% to 100%). I also found very excellent new cognates/very likely cognates for "tiltean", as well as a likely PIE root-word for that word: yet I expect that such a form with such meanings was not exclusive to PIE.

description: We report on graphene-passivated ferromagnetic electrodes (GPFE) for spin devices. GPFE are shown to act as spin-polarized oxidation-resistant electrodes. The direct coating of nickel with few layer graphene through a readily scalable chemical vapour deposition (CVD) process allows the preservation of an unoxidized nickel surface upon air exposure. Fabrication and measurement of complete reference tunneling spin valve structures demonstrates that the GPFE is maintained as a spin polarizer and also that the presence of the graphene coating leads to a specific sign reversal of the magneto-resistance. Hence, this work highlights a novel oxidation-resistant spin source which further unlocks low cost wet chemistry processes for spintronics devices.

description: We present results demonstrating the time resolution and $μ$/e separation capabilities with a new concept of an EAS detector capable for measurements of cosmic rays arriving with large zenith angles. This kind of detector has been designed to be a part of a large area (several square kilometers) surface array designed to measure Ultra High Energy (10-200 PeV) $τ$ neutrinos using the Earth-skimming technique. A criteria to identify electron-gammas is also shown and the particle identification capability is tested by measurements in coincidence with the KASKADE-GRANDE experiment in Karlsruhe, Germany.
