description: This paper proves the existence and uniqueness results (in the sense of maximally defined regularity) as well as the stability analysis for the solutions to a class of nonlocal fully-nonlinear parabolic systems, where the nonlocality stems from the flow feature (controlled by an external temporal parameter) of the systems. The derived mathematical results generalize the theory of stochastic differential games to incorporate with behavioral factors such as time-inconsistent preferences, which facilitate developments of many studies in financial economics including robust stochastic controls and games under relative performance concerns. Moreover, with the well-posedness results, we establish a general multidimensional Feynman--Kac formula in the presence of nonlocality (time inconsistency).

description: Let $U$ be a set of polynomials of degree at most $k$ over $\mathbb{F}_q$, the finite field of $q$ elements. Assume that $U$ is an intersecting family, that is, the graphs of any two of the polynomials in $U$ share a common point. Adriaensen proved that the size of $U$ is at most $q^k$ with equality if and only if $U$ is the set of all polynomials of degree at most $k$ passing through a common point. In this manuscript, using a different, polynomial approach, we prove a stability version of this result, that is, the same conclusion holds if $|U|>q^k-q^{k-1}$. We prove a stronger result when $k=2$. For our purposes, we also prove the following results. If the set of directions determined by the graph of $f$ is contained in an additive subgroup of $\mathbb{F}_q$, then the graph of $f$ is a line. If the set of directions determined by at least $q-\sqrt{q}/2$ affine points is contained in the set of squares/non-squares plus the common point of either the vertical or the horizontal lines, then up to an affinity the point set is contained in the graph of some polynomial of the form $αx^{p^k}$.

description: Standard electron optics predicts Larmor image rotation in the magnetic lens field of a TEM. Introducing the possibility to produce electron vortex beams with quantized orbital angular momentum brought up the question of their rotational dynamics in the presence of a magnetic field. Recently, it has been shown that electron vortex beams can be prepared as free electron Landau states showing peculiar rotational dynamics, including no and cyclotron (double-Larmor) rotation. Additionally very fast Gouy rotation of electron vortex beams has been observed. In this work a model is developed which reveals that the rotational dynamics of electron vortices are a combination of slow Larmor and fast Gouy rotations and that the Landau states naturally occur in the transition region in between the two regimes. This more general picture is confirmed by experimental data showing an extended set of peculiar rotations, including no, cyclotron, Larmor and rapid Gouy rotations all present in one single convergent electron vortex beam.

description: Energy is one of the most important requirements in the world to function properly. Its demand goes on increasing day by day. As we are all aware, energy and fuel cost are rising and negative impact of global warming are more visible. Parabolic trough is the most efficient to concentrate the solar energy when comparing other solar thermal energy technology. In this paper, analytical study has been carried out for the parabolic solar collector. By the use of analytical data, fabrication of parabolic trough has been carried out and experimental investigation has been done with glass cover and without glass cover in parabolic solar collector.

description: Layered transition metal dichalcogenides MoTe$_2$ and WTe$_2$ share almost similar lattice constants as well as topological electronic properties except their structural phase transitions. While the former shows a first-order phase transition between monoclinic and orthorhombic structures, the latter does not. Using a recently proposed van der Waals density functional method, we investigate structural stability of the two materials and uncover that the disparate phase transitions originate from delicate differences between their interlayer bonding states near the Fermi energy. By exploiting the relation between the structural phase transitions and the low energy electronic properties, we show that a charge doping can control the transition substantially, thereby suggesting a way to stabilize or to eliminate their topological electronic energy bands.

description: We consider the energy-critical (corotational) 1-equivariant wave maps into the two-sphere. By the seminal work [53] of Raphaël and Rodnianski, there is an open set of initial data whose forward-in-time development blows up in finite time with the blow-up rate $λ(t)=(T-t)e^{-\sqrt{|\log(T-t)|}+O(1)}$. In this paper, we show that this $e^{O(1)}$-factor in fact converges to the universal constant $2e^{-1}$, and hence these solutions contract at the universal rate $λ(t)=2e^{-1}(T-t)e^{-\sqrt{|\log(T-t)|}}(1+o_{t\to T}(1))$. Our proof is inspired by recent works on type-II blow-up dynamics for parabolic equations. The key improvement is in the construction of an explicit invariant subspace decomposition for the linearized operator perturbed by the scaling generator in the dispersive case, from which we obtain a more precise ODE system determining $λ(t)$.

description: The jamming transition is ubiquitous. It is present in granular matter, colloids, glasses, and many other systems. Yet, it defines a critical point whose properties still need to be fully understood. A major breakthrough came about when the replica formalism was extended to build a mean-field theory that provides an exact description of the jamming transition of spherical particles in the infinite-dimensional limit. While such theory explains the jamming critical behavior of both soft and hard spheres, investigating the transition in finite-dimensional systems poses very difficult and different problems, in particular from the numerical point of view. Soft particles are modeled by continuous potentials; thus, their jamming point can be reached through efficient energy minimization algorithms. In contrast, the latter methods are inapplicable to hard-sphere (HS) systems since the interaction energy among the particles is always zero by construction. To overcome these difficulties, here we recast the jamming of hard spheres as a constrained optimization problem and introduce the CALiPPSO algorithm, capable of readily producing jammed HS packings without including any effective potential. This algorithm brings a HS configuration of arbitrary dimensions to its jamming point by solving a chain of linear optimization problems. We show that there is a strict correspondence between the force balance conditions of jammed packings and the properties of the optimal solutions of CALiPPSO, whence we prove analytically that our packings are always isostatic and in mechanical equilibrium. Furthermore, using extensive numerical simulations, we show that our algorithm is able to probe the complex structure of the free-energy landscape, finding qualitative agreement with mean-field predictions. We also characterize the algorithmic complexity of CALiPPSO and provide an open-source implementation of it.

On the choice of the splitting ratio for the split likelihood ratio test

description: The recently introduced framework of universal inference provides a new approach to constructing hypothesis tests and confidence regions that are valid in finite samples and do not rely on any specific regularity assumptions on the underlying statistical model. At the core of the methodology is a split likelihood ratio statistic, which is formed under data splitting and compared to a cleverly selected universal critical value. As this critical value can be very conservative, it is interesting to mitigate the potential loss of power by careful choice of the ratio according to which data are split. Motivated by this problem, we study the split likelihood ratio test under local alternatives and introduce the resulting class of noncentral split chi-square distributions. We investigate the properties of this new class of distributions and use it to numerically examine and propose an optimal choice of the data splitting ratio for tests of composite hypotheses of different dimensions.
The Velocity Dispersion Function for Quiescent Galaxies in the Local Universe

description: We investigate the distribution of central velocity dispersions for quiescent galaxies in the SDSS at $0.03 \leq z \leq 0.10$. To construct the field velocity dispersion function (VDF), we construct a velocity dispersion complete sample of quiescent galaxies with Dn4000$ > 1.5$. The sample consists of galaxies with central velocity dispersion larger than the velocity dispersion completeness limit of the SDSS survey. Our VDF measurement is consistent with previous field VDFs for $σ> 200$ km s$^{-1}$. In contrast with previous results, the VDF does not decline significantly for $σ< 200$ km s$^{-1}$. The field and the similarly constructed cluster VDFs are remarkably flat at low velocity dispersion ($σ< 250$ km s$^{-1}$). The cluster VDF exceeds the field for $σ> 250$ km s$^{-1}$ providing a measure of the relatively larger number of massive subhalos in clusters. The VDF is a probe of the dark matter halo distribution because the measured central velocity dispersion may be directly proportional to the dark matter velocity dispersion. Thus the VDF provides a potentially powerful test of simulations for models of structure formation.

title: Institutional Betrayal Related to Sexual Trauma in Military Service Members and Veterans: An Examination of Posttraumatic Sequelae
Creators: name: Andresen, Felicia
Publisher: name: Utah State University
Year: 2022

description: Military sexual harassment and/or assault (MSH/A) is pervasive and destructive. MSH/A survivors who believe the institution played a role in the traumatic experience by failing to respond in a supportive manner or for failing to keep them safe may feel betrayed by the military itself, a concept referred to as institutional betrayal. Previous research suggests it is more harmful to be abused by trusted others or institutions due to the violation of trust. This two-study dissertation explored experiences of MSH/A-related institutional betrayal to identify survivors at-risk for worse posttraumatic outcomes.
Study #1 evaluated whether PTSD explained the relationship between MSH/A type and somatic symptom severity, and whether this relationship depended on experiences of institutional betrayal. Study #2 examined whether exposure to killing and/or death during combat strengthened the link between institutional betrayal and risk for suicidal behaviors. Findings revealed MSH/A perpetrators were typically male, a fellow servicemember, unit member, battle buddy, or first-line leader. The most common experiences of MSH/A-related institutional betrayal included responding inadequately once MSH/A was reported, creating an environment in which MSH/A seemed normal or common, making it difficult to report MSH/A, not taking proactive steps to prevent MSH/A, and mishandling the case once reported. PTSD explained the link between MSH and somatic symptom severity, but contrary to hypotheses in Study #1 and #2, institutional betrayal was unrelated to somatic symptom severity and suicide risk. Alternatively, MSH was an independent risk factor for severe posttraumatic distress, including suicide risk, somatic symptom severity, PTSD, depression, and alcohol abuse when compared to MSA. MSH is often the precursor to MSA, but the experience goes unreported or is not taken seriously by leadership, which likely contributes to the cycle of violence and maintains the abuse.
This dissertation illustrates that any type of sexual violence is demeaning and has the potential to cause harm. Prevention strategies are needed to thwart MSH, thereby decreasing risk for MSA, suicidal behavior, somatic symptom severity, PTSD, depression, and alcohol abuse. It is imperative that the Department of Defense increases accountability for perpetrators and ensures leadership does not tolerate sexual violence or retaliate upon disclosure.

description: Recent advances in transformer-based architectures which are pre-trained in self-supervised manner have shown great promise in several machine learning tasks. In the audio domain, such architectures have also been successfully utilised in the field of speech emotion recognition (SER). However, existing works have not evaluated the influence of model size and pre-training data on downstream performance, and have shown limited attention to generalisation, robustness, fairness, and efficiency. The present contribution conducts a thorough analysis of these aspects on several pre-trained variants of wav2vec 2.0 and HuBERT that we fine-tuned on the dimensions arousal, dominance, and valence of MSP-Podcast, while additionally using IEMOCAP and MOSI to test cross-corpus generalisation. To the best of our knowledge, we obtain the top performance for valence prediction without use of explicit linguistic information, with a concordance correlation coefficient (CCC) of .638 on MSP-Podcast. Furthermore, our investigations reveal that transformer-based architectures are more robust to small perturbations compared to a CNN-based baseline and fair with respect to biological sex groups, but not towards individual speakers. Finally, we are the first to show that their extraordinary success on valence is based on implicit linguistic information learnt during fine-tuning of the transformer layers, which explains why they perform on-par with recent multimodal approaches that explicitly utilise textual information. Our findings collectively paint the following picture: transformer-based architectures constitute the new state-of-the-art in SER, but further advances are needed to mitigate remaining robustness and individual speaker issues. To make our findings reproducible, we release the best performing model to the community.

description: In the field of bioconjugates, the focus on antibody – drug conjugates (ADCs) with novel payloads beyond the traditional categories of potent cytotoxic agents is increasing. These innovative ADCs exhibit various molecular formats, ranging from small-molecule payloads, such as immune agonists and proteolytic agents, to macromolecular payloads, such as oligonucleotides and proteins. This review offers an in-depth exploration of unconventional strategies for designing conjugates with novel mechanisms of action and notable examples of approaches that show promising prospects. Representative examples of novel format payloads and their classification, attributes, and appropriate conjugation techniques are discussed in detail. The existing basic technologies used to manufacture ADCs can be directly applied to synthesize novel formatted conjugates. However, a wide variety of new payloads require the creation of customized technologies adapted to the unique characteristics of these payloads. Consequently, fundamental technologies, such as conjugation methods aimed at achieving high drug – antibody ratios and developing stable crosslinkers, are likely to become increasingly important research areas in the future.

description: Die Differenzierung vom Wettbewerb in einem sich ständig ändernden Umfeld ist für Unternehmen zunehmend herausfordernd. Neue Technologien und steigende Kund*innenerwartungen erfordern eine genauere Betrachtung der Kund*inneninteraktionen. Künstliche Intelligenz hebt Personalisierung auf die nächste Ebene und vereinfacht das Sammeln von Daten, die für den Aufbau einer besseren Kundenbeziehung genutzt werden können. Trotz der vermehrten wissenschaftlichen Untersuchungen von KI im Marketing, bleibt unklar, wie KI-basierte Personalisierung die Kaufzufriedenheit beeinflusst. Diese Arbeit zielt darauf ab, diese Forschungslücke durch eine Literaturanalyse und eine induktive qualitative Studie zu schließen. Das entwickelte Modell zeigt, dass die KI-Personalisierung je nach den gegebenen Komponenten sowohl positive als auch negative Auswirkungen auf die Kaufzufriedenheit haben kann. Außerdem enthüllt die Forschung, dass einige Unternehmen Kaufzufriedenheit nicht vollständig erfassen und mit anderen Faktoren wie der Kund*innenzufriedenheit gleichsetzen.
description: Differentiating from the competition in a constantly changing environment is increasingly challenging for companies. New technologies and rising customer expectations require a closer look at customer interactions. Artificial intelligence takes personalization to the next level and simplifies the collection of data, which can be used to build a better customer relationship. Although the scientific study of AI in marketing has grown in recent years, it remains unclear how AI-based personalization affects purchase satisfaction. This paper aims to fill this research gap through a literature review and an inductive qualitative study. The developed model shows that AI personalization can have both positive and negative effects on purchase satisfaction, depending on different components. In addition, research has revealed that some companies do not fully capture purchase satisfaction and equate it with other factors such as customer satisfaction.

The aim of this tutorial is to highlight a novel chapter of control theory, dealing with applications to social systems, to the attention of the broad research community. This paper is the first part of the tutorial, and it is focused on the most classical models of social dynamics and on their relations to the recent achievements in multi-agent systems.

description: By considering a solvable driven-dissipative quantum model, we demonstrate that continuous second order phase transitions in dissipative systems may occur without an accompanying spontaneous symmetry breaking. As such, the underlying mechanism for this type of transition is qualitatively different from that of continuous equilibrium phase transitions. In our model, the transition is solely a result of the interplay between Hamiltonian and dissipative dynamics and manifests as a non-analyticity in the steady state $\hatρ_\mathrm{ss}$ in the thermodynamic limit. Expectations of local observables are continuous but typically with discontinuous first order derivatives in agreement with second order phase transitions. While the model, a large number of driven two-level systems under collective dissipation, is in some sense fully connected, mean-field results are incapable of capturing the full picture.

Rotor-Routing Induces the Only Consistent Sandpile Torsor Structure on Plane Graphs

description: We make precise and prove a conjecture of Klivans about actions of the sandpile group on spanning trees. More specifically, the conjecture states that there exists a unique ``suitably nice'' sandpile torsor structure on plane graphs which is induced by rotor-routing. First, we rigorously define a sandpile torsor algorithm (on plane graphs) to be a map which associates each plane graph (i.e., planar graph with an appropriate ribbon structure) with a free transitive action of its sandpile group on its spanning trees. Then, we define a notion of consistency, which requires a torsor algorithm to be preserved with respect to a certain class of contractions and deletions. Using these definitions, we show that the rotor-routing sandpile torsor algorithm is consistent. Furthermore, we demonstrate that there are only three other consistent algorithms on plane graphs, which all have the same structure as rotor-routing. We also define sandpile torsor algorithms on regular matroids and suggest a notion of consistency in this context. We conjecture that the Backman-Baker-Yuen algorithm is consistent, and that there are only three other consistent sandpile torsor algorithms on regular matroids, all with the same structure.

description: In this work we discuss the existence of time-translation symmetry breaking in a kicked infinite-range-interacting clean spin system described by the Lipkin-Meshkov-Glick model. This Floquet time crystal is robust under perturbations of the kicking protocol, its existence being intimately linked to the underlying $\mathbb{Z}_2$ symmetry breaking of the time-independent model. We show that the model being infinite-range and having an extensive amount of symmetry breaking eigenstates is essential for having the time-crystal behaviour. In particular we discuss the properties of the Floquet spectrum, and show the existence of doublets of Floquet states which are respectively even and odd superposition of symmetry broken states and have quasi-energies differing of half the driving frequencies, a key essence of Floquet time crystals. Remarkably, the stability of the time-crystal phase can be directly analysed in the limit of infinite size, discussing the properties of the corresponding classical phase space. Through a detailed analysis of the robustness of the time crystal to various perturbations we are able to map the corresponding phase diagram. We finally discuss the possibility of an experimental implementation by means of trapped ions.

description: We consider the quantum kinetic-theory description for interacting massive spin-half fermions using the Wigner function formalism. We derive a general kinetic theory description assuming that the spin effects appear at the classical and quantum level. To track the effect of such different contributions we use the semi-classical expansion method to obtain the generalized dynamical equations including spin, analogous to classical Boltzmann equation. This approach can be used to obtain a collision kernel involving local as well as non-local collisions among the microscopic constituent of the system and eventually, a framework of spin hydrodynamics ensuring the conservation of the energy-momentum tensor and total angular momentum tensor.

description: We demonstrate optical spin polarization of the neutrally-charged silicon-vacancy defect in diamond ($\mathrm{SiV^{0}}$), an $S=1$ defect which emits with a zero-phonon line at 946 nm. The spin polarization is found to be most efficient under resonant excitation, but non-zero at below-resonant energies. We measure an ensemble spin coherence time $T_2>100~\mathrm{μs}$ at low-temperature, and a spin relaxation limit of $T_1>25~\mathrm{s}$. Optical spin state initialization around 946 nm allows independent initialization of $\mathrm{SiV^{0}}$ and $\mathrm{NV^{-}}$ within the same optically-addressed volume, and $\mathrm{SiV^{0}}$ emits within the telecoms downconversion band to 1550 nm: when combined with its high Debye-Waller factor, our initial results suggest that $\mathrm{SiV^{0}}$ is a promising candidate for a long-range quantum communication technology.

description: In this paper, we describe the PALM model system 6.0. PALM (formerly an abbreviation for Parallelized Large-eddy Simulation Model and now an independent name) is a Fortran-based code and has been applied for studying a variety of atmospheric and oceanic boundary layers for about 20 years. The model is optimized for use on massively parallel computer architectures. This is a follow-up paper to the PALM 4.0 model description in Maronga et al. (2015). During the last years, PALM has been significantly improved and now offers a variety of new components. In particular, much effort was made to enhance the model with components needed for applications in urban environments, like fully interactive land surface and radiation schemes, chemistry, and an indoor model. This paper serves as an overview paper of the PALM 6.0 model system and we describe its current model core. The individual components for urban applications, case studies, validation runs, and issues with suitable input data are presented and discussed in a series of companion papers in this special issue.
The Merino--Welsh conjecture for split matroids

description: In 1999 Merino and Welsh conjectured that evaluations of the Tutte polynomial of a graph satisfy an inequality. In this short article we show that the conjecture generalized to matroids holds for the large class of all split matroids by exploiting the structure of their lattice of cyclic flats. This class of matroids strictly contains all paving and copaving matroids.

description: Diese Arbeit versucht die Grundlage für die Resilienz von Mitarbeitenden auf Basis gelebter Werte zu untersuchen und fokussiert sich auf den Wert des Vertrauens in Kombination mit dem Resilienzfaktor der Selbstwirksamkeit, da diese Thematik in der Resilienzforschung bisher vernachlässigt wurde. Aufgrund der Besonderheiten und Relevanz von Familienunternehmen wird auf diese Gruppe fokussiert. Im theoretischen Teil wurde ein Modell zur Erklärung der Wirkzusammenhänge herausgearbeitet, welches im empirischen Teil mittels einer Primärerhebung mit einem Onlinefragbogen geprüft und validiert wurde. Das Ergebnis ist, dass das Vertrauen der Mitarbeitenden in ihre Vorgesetzten einen positiven Zusammenhang mit ihrer Selbstwirksamkeit hat, wobei diese Verbindung durch die Motivation beeinflusst wird. Die Selbstwirksamkeit ihrerseits hat wiederum einen positiven Einfluss auf die individuelle Resilienz, wodurch die Verbindung zwischen Vertrauen und Resilienz nachgewiesen wurde.
description: This thesis attempts to examine the basis for employee resilience because of the lived values within the company and focuses on the value of trust in combination with the resilience factor of self-efficacy, as this topic has been neglected in resilience research to date. Due to the special characteristics and relevance of family businesses, the focus lies on this group. In the theoretical part, a model was developed to explain the interrelationships, which was tested and validated in the empirical part by means of a primary survey with an online questionnaire. The result is that employees' trust in their superiors has a positive connection with their self-efficacy, whereby this connection is influenced by motivation. Self-efficacy, in turn, has a positive influence on individual resilience, thus demonstrating the link between trust and resilience.

description: We describe in detail the method used in our previous work arXiv:1611.10344 to study the Wilson-Fisher critical points nearby generalized free CFTs, exploiting the analytic structure of conformal blocks as functions of the conformal dimension of the exchanged operator. Our method is equivalent to the mechanism of conformal multiplet recombination set up by null states. We compute, to the first non-trivial order in the $ε$-expansion, the anomalous dimensions and the OPE coefficients of infinite classes of scalar local operators using just CFT data. We study single-scalar and $O(N)$-invariant theories, as well as theories with multiple deformations. When available we agree with older results, but we also produce a wealth of new ones. Unitarity and crossing symmetry are not used in our approach and we are able to apply our method to non-unitary theories as well. Some implications of our results for the study of the non-unitary theories containing partially conserved higher-spin currents are briefly mentioned.

description: The reaction of laser‐ablated iridium atoms with dinitrogen molecules and nitrogen atoms yield several neutral and ionic iridium dinitrogen complexes such as Ir(N2), Ir(N2)+, Ir(N2)2, Ir(N2)2−, IrNNIr, as well as the nitrido complexes IrN, Ir(N)2 and IrIrN. These reaction products were deposited in solid neon, argon and nitrogen matrices and characterized by their infrared spectra. Assignments of vibrational bands are supported by ab initio and first principle calculations as well as 14/15N isotope substitution experiments. The structural and electronic properties of the new dinitrogen and nitrido iridium complexes are discussed. While the formation of the elusive dinitrido complex Ir(N)2 was observed in a subsequent reaction of IrN with N atoms within the cryogenic solid matrices, the threefold coordinated iridium trinitride Ir(N)3 could not be observed so far.
Decomposition of Triple Collinear Splitting Functions

description: In the kinematic region where three particles $i$, $j$, $k$ are collinear, the multi-parton scattering amplitudes factorise into a product of a triple collinear splitting function and a multi-parton scattering amplitude with two fewer particles. These triple collinear splitting functions contain both iterated single unresolved contributions, and genuine double unresolved contributions. We make this explicit by rewriting the known triple collinear splitting functions in terms of products of two-particle splitting functions, and a remainder that is explicitly finite when any two of $\{i,j,k\}$ are collinear. We analyse all of the single unresolved singularities present in the remainder.

A note on Hurwitz's inequality

description: Given a simple closed plane curve $Γ$ of length $L$ enclosing a compact convex set $K$ of area $F$, Hurwitz found an upper bound for the isoperimetric deficit, namely $L^2-4πF\leq π|F_{e}|$, where $F_{e}$ is the algebraic area enclosed by the evolute of $Γ$. In this note we improve this inequality finding strictly positive lower bounds for the deficit $π|F_{e}|-Δ$, where $Δ=L^{2}-4πF$. These bounds involve wether the visual angle of $Γ$ or the pedal curve associated to $K$ with respect to the Steiner point of $K$ or the $\mathcal{L}^{2}$ distance between $K$ and the Steiner disk of $K$. For each established inequality we study when equality holds. This occurs for those compact convex sets being bounded by a curve parallel to an hypocycloid of $3, 4$ or $5$ cusps or the Minkowski sum of this kind of sets.

title: Evaluation of the Geothermal Potential of the Camas Prairie, South-Central Idaho
Creators: name: Smith, Connor J.
Publisher: name: Utah State University

description: The area studied in this thesis was assessed based on the analysis of a water sample collected from the exploratory well USU Camas-1. The water sample was characterized and compared to other water samples collected and analyzed during a previous phase of this project according to its water chemistry.
Lithologic, geophysical, and temperature logs were also used to assess the study area. The depth sensitive data was analyzed to determine the characteristics of the formation as they relate to the favorable parameters of a geothermal resource, those being permeability of the subsurface, heat, and the presence of a clay seal.
The analyses suggest that USU Camas-1 falls short of being a high-temperature resource capable of generating electricity efficiently. However, temperatures are high enough for the resource to be developed as a low-temperature asset that could be utilized to heat buildings in the area.
