description: Wind- and current-driven flotsam, oil spills, pollutants, and nutrients, approaching the nearshore will frequently appear to park just beyond the break zone, where waves break. Moreover, the portion of these tracers that beach will do so only after a long time. Explaining why these tracers park and at what rate they reach the shore has important implications on a variety of different nearshore environmental issues, including the determination of what subscale processes are essential in computer models for the simulation of pollutant transport in the nearshore. Using a simple model we provide an explanation for the underlying mechanism responsible for the parking of tracers, the role played by the bottom topography, and the non-uniform dispersion which leads, in some circumstances, to the eventual landing of all or a portion of the tracers. We refer to the parking phenomenon in this environment as nearshore sticky waters.

New Brezis-Van Schaftingen-Yung-Sobolet type inequalities connected with maximal inequalities and one parameter families of operators

Year: 2022

description: Motivated by the recent characterization of Sobolev spaces due to Brezis--VanSchaftingen--Yung we prove new weak-type inequalities for one parameterfamilies of operators connected with mixed norm inequalities. The novelty ofour approach comes from the fact that the underlying measure spaceincorporates the parameter as a variable. We also show that our framework canbe adapted to treat related characterizations of Sobolev spaces obtainedearlier by Bourgain--Nguyen. The connection to classical and fractional orderSobolev spaces is shown through the use of generalized Riesz potential spacesand the Caffarelli--Silvestre extension principle. Higher order inequalitiesare also considered. We indicate many examples and applications to PDE's anddifferent areas of Analysis, suggesting a vast potential for future research.In a different direction, and inspired by methods originally due to Gagliardoand Garsia, we obtain new maximal inequalities which combined with mixed norminequalities are applied to obtain Brezis--Van Schaftingen--Yung typeinequalities in the context of Calderón--Campanato spaces. In particular,Log versions of the Gagliardo--Brezis--Van Schaftingen--Yung spaces areintroduced and compared with corresponding limiting versions ofCalderón--Campanato spaces, resulting in a sharpening of recentinequalities due to Crippa--De Lellis and Brué--Nguyen.

description: In infinite ergodic theory, two distributional limit theorems are well-known. One is characterized by the Mittag-Leffler distribution for time averages of $L^1(m)$ functions, i.e., integrable functions with respect to an infinite invariant measure. The other is characterized by the generalized arc-sine distribution for time averages of non-$L^1(m)$ functions. Here, we provide another distributional behavior of time averages of non-$L^1(m)$ functions in one-dimensional intermittent maps where each has an indifferent fixed point and an infinite invariant measure. Observation functions considered here are non-$L^1(m)$ functions which vanish at the indifferent fixed point. We call this class of observation functions weak non-$L^1(m)$ function. Our main result represents a first step toward a third distributional limit theorem, i.e., a distributional limit theorem for this class of observables, in infinite ergodic theory. To prove our proposition, we propose a stochastic process induced by a renewal process to mimic a Birkoff sum of a weak non-$L^1(m)$ function in the one-dimensional intermittent maps.

description: Ion specificity and related Hofmeister effects, ubiquitous in aqueous systems, can have spectacular consequences in hydrated clays, where ion-specific nanoscale surface forces can determine large scale cohesive, swelling and shrinkage behaviors of soil and sediments. We have used a semi-atomistic computational approach and examined sodium, calcium and aluminum counterions confined with water between charged surfaces representative of clay materials, to show that ion-water structuring in nanoscale confinement is at the origin of surface forces between clay particles which are intrinsically ion-specific. When charged surfaces strongly confine ions and water, the amplitude and oscillations of the net pressure naturally emerge from the interplay of electrostatics and steric effects, which can not be captured by existing theories. Increasing confinement and surface charge densities promote ion-water structures that increasingly deviate from the ions' bulk hydration shells, being strongly anisotropic and persistent, and self-organizing into optimized, nearly solid-like assemblies where hardly any free water is left. In these conditions, strongly attractive interactions can prevail between charged surfaces, due to the dramatically reduced dielectric screening of water and the highly organized water-ion structures. By unravelling the ion-specific nature of these nanoscale interactions, we provide evidence that ion-specific solvation structures determined by confinement are at the origin of ion specificity in clays and potentially a broader range of confined aqueous systems.

description: We propose a correction to the conventional Rytov approximation (RA) and investigate its performance for predicting wave scattering under strong scattering conditions. An important motivation for the correction and investigation is to help in the development of better models for inverse scattering. The correction is based upon incorporating the high frequency theory of inhomogeneous wave propagation for lossy media into the RA formulation. We denote the technique as the extended Rytov approximation for lossy media (xRA-LM). xRA-LM significantly improves upon existing non-iterative linear scattering approximations such as RA and the Born approximation (BA) by providing a validity range for the permittivity of the objects of up to 50 times greater than RA. We demonstrate the technique by providing results for predicting wave scattering from piece-wise homogeneous scatterers in a two-dimensional (2D) region. Numerical investigation of the performance of xRA-LM for solving direct problem show that xRA-LM can accurately predict wave scattering by electrically large, low-loss scatterers with high complex permittivity ($ε_r> 50+5j$). To the best of our knowledge, this is the first non-iterative, linear approximate wave scattering model which has a large validity range in terms of both permittivity and electrical size.

description: The fair division literature in economics considers how to divide resources between multiple agents such that the allocation is envy-free: each agent receives their favorite piece. Researchers have developed a variety of fair division protocols for the most standard setting, where the agents want to split a single item, however, the protocols are highly intricate and the proofs of envy-freeness involve tedious case analysis. We propose Slice, a domain specific language for fair-division. Programs in our language can be converted to logical formulas encoding envy-freeness and other target properties. Then, the constraints can be dispatched to automated solvers. We prove that our constraint generation procedure is sound and complete. We also report on a prototype implementation of Slice, which we have used to automatically check envy-freeness for several protocols from the fair division literature.

description: In this paper, we establish a connection between zonoids (a concept from classical convex geometry) and the distinguishability norms associated to quantum measurements, or POVMs (Positive Operator-Valued Measures), recently introduced in quantum information theory. This correspondence allows us to state and prove the POVM version of classical results from the local theory of Banach spaces about the approximation of zonoids by zonotopes. We show that on $\mathbf{C}^d$, the uniform POVM (the most symmetric POVM) can be sparsified, i.e. approximated by a discrete POVM, the latter having only $O(d^2)$ outcomes. We also show that similar (but weaker) approximation results actually hold for any POVM on $\mathbf{C}^d$. By defining an appropriate notion of tensor product for zonoids, we are then able to extend our results to the multipartite setting: we show, roughly speaking, that local POVMs may be sparsified locally. In particular, the local uniform POVM on $\mathbf{C}^{d_1}\otimes\cdots\otimes\mathbf{C}^{d_k}$ can be approximated by a discrete POVM which is local and has $O(d_1^2\times\cdots\times d_k^2)$ outcomes.

description: Cyclic structure and dynamics are of great interest in both the fields of stochastic processes and nonequilibrium statistical physics. In this paper, we find a new symmetry of the Brownian motion named as the quasi-time-reversal invariance. It turns out that such an invariance of the Brownian motion is the key to prove the cycle symmetry for diffusion processes on the circle, which says that the distributions of the forming times of the forward and backward cycles, given that the corresponding cycle is formed earlier than the other, are exactly the same. With the aid of the cycle symmetry, we prove the strong law of large numbers, functional central limit theorem, and large deviation principle for the sample circulations and net circulations of diffusion processes on the circle. The cycle symmetry is further applied to obtain various types of fluctuation theorems for the sample circulations, net circulation, and entropy production rate.

description: In this article we construct Symmetric operations for all primes (previously known only for p=2). These unstable operations are more subtle than the Landweber-Novikov operations, and encode all p-primary divisibilities of characteristic numbers. Thus, taken together (for all primes) they plug the gap left by the Hurewitz map L ---> Z[b_1,b_2,...], providing an important structure on Algebraic Cobordism. Applications include: questions of rationality of Chow group elements - see [11], and the structure of the Graded Algebraic Cobordism. We also construct Steenrod operations of T.tom Dieck-style in Algebraic Cobordism. These unstable multiplicative operations are more canonical and subtle than Quillen-style operations, and complement the latter.

description: This work examines the problem of learning an unknown von Neumann measurement of dimension $d$ from a finite number of copies. To obtain a faithful approximation of the given measurement we are allowed to use it $N$ times. Our main goal is to estimate the asymptotic behavior of the maximum value of the average fidelity function $F_d$ for a general $N \rightarrow 1$ learning scheme. We show that $F_d = 1 - Θ\left(\frac{1}{N^2}\right)$ for arbitrary but fixed dimension $d$. In addition to that, we compared various learning schemes for $d=2$. We observed that the learning scheme based on deterministic port-based teleportation is asymptotically optimal but performs poorly for low $N$. In particular, we discovered a parallel learning scheme, which despite its lack of asymptotic optimality, provides a high value of the fidelity for low values of $N$ and uses only two-qubit entangled memory states.

description: Maximally supersymmetric Yang--Mills theory (N=4 SYM) is conformal for any value of the coupling. Lattice regularization breaks conformality through the introduction of a non-zero lattice spacing and a finite lattice volume. This proceedings presents ongoing numerical computations of conformal scaling dimensions in lattice N=4 SYM, based on a lattice formulation that exactly preserves a supersymmetry sub-algebra at non-zero lattice spacing. The main targets are the non-trivial anomalous dimension of the Konishi operator, as well as a mass anomalous dimension extracted from the eigenvalue mode number of the fermion operator. The latter is expected to vanish in the conformal continuum theory, providing insight into the interplay of lattice discretization and conformality.

Die Grundlage hierfür bilden Erhebungen in vier deutschen Bundesländern, die von 2018 bis 2021 durchgeführt wurden. Es zeigt sich eine als „fragmentarisch“ bezeichnete Steuerung, die sich vornehmlich auf Maßnahmen der Inputsteuerung beschränkt und Elemente der Outputsteuerung weitgehend außen vor lässt. Innerschulisch können verschiedene Verhandlungsmodi über den Einsatz der förderpädagogischen Lehrkräfte gefunden werden. Es erfolgt eine Verlagerung der Verantwortung für die Ausgestaltung inklusiver Bildung auf die Einzelschule und insbesondere auf die förderpädagogischen Lehrkräfte.
description: From the perspective of educational governance, the paper examines how and by which actors of the multilevel school system the job clarification of special educational needs teachers in primary schools in the context of inclusive education is regulated. The analysis is based on surveys conducted in four german federal states from 2018 to 2021. The results show a “fragmentary form” of management, which is primarily limited to measures of input control and largely excludes elements of output control. Within the schools, various modes of negotiation about the use of special educational needs teachers were found. The responsibility for the design of inclusive education is shifted to the individual school and in particular to the special educational needs teachers.

The paper employs document analyses and qualitative case studies to examine past beauty companies' business and decision-making practices involving African American women using visual and textual analysis. The findings state that African American female consumers require beauty brand companies to recognize their value in terms of representation, awareness of social injustices that impact Black consumers, and develop culture-centered content that invites inclusiveness in the marketing and promotion of beauty brand services. Sociocultural implications are discussed in the paper to advance marketing and advertising research centering Black female consumers.

A sub-tree inside the factor graph is first extracted randomly; Belief Propagation is then used as a perfect sampler to generate a configuration on the tree given the boundary conditions and the procedure is iterated. This appoach is best adapted for locally tree like graphs, it is therefore tested on the hard cases of spin-glass models for random graphs demonstrating its state-of-the art status in those cases.

Serial Founders: Does Prior Experience Pay Off in Leveraged Buyouts?

description: This paper explores the impact of a founder's prior experiences on the price of their business during a private equity leveraged buyout (LBO) of their company. The paper reviews the existing literature on serial founders, which is predominately focused on venture capital (i.e., early stage) private investments. The paper uses relative valuation multiples, rather than absolute dollars raised, to determine whether repeat founders are raising more money due to their prior experiences or simply because they have larger businesses. Using a dataset of U.S. LBOs, this study finds that there is a significant difference in revenue multiples and EBITDA multiples paid for repeat founders versus their novice counterparts. The paper proposes a theoretical framework to explain this potential founder effect, suggesting that variations in cash flows and risk profiles may contribute to differences in valuations for repeat founders. The paper also contends that principal-agent problems within private equity firms may play a role in the disparity between relative multiples for these two groups. To illustrate the plausibility of these hypotheses, the paper examines the case of EverCommerce, a company that went through the LBO process with a repeat founder.

Here H is a member of a sufficiently positive linear system and Z is a 1-dimensional subscheme of it. The associated sheaf is the ideal sheaf of $Z\subset H$, pushed forward to X and considered as a certain Joyce-Song pair in the derived category of X. We express these invariants in terms of the MNOP invariants of X.

description: Quantum spin Hall (QSH) insulators have unique electronic properties, comprising a band gap in their two-dimensional interior and one-dimensional spin-polarized edge states in which current flows ballistically. In scanning tunneling microscopy (STM), the edge states manifest themselves as a localized density of states. However, there is a significant research gap between the observation of edge states in nanoscale spectroscopy, and the detection of ballistic transport in edge channels which typically relies on transport experiments with microscale lithographic contacts. Here, we study few-layer films of the three-dimensional topological insulator (Bi$_{x}$Sb$_{1-x})_2$Te$_3$, for which a topological transition to a two-dimensional topological QSH insulator phase has been proposed. Indeed, an edge state in the local density of states is observed within the band gap. Yet, in nanoscale transport experiments with a four-tip STM, 2 and 3 quintuple layer films do not exhibit a ballistic conductance in the edge channels. This demonstrates that the detection of edge states in spectroscopy can be misleading with regard to the identification of a QSH phase. In contrast, nanoscale multi-tip transport experiments are a robust method for effectively pinpointing ballistic edge channels, as opposed to trivial edge states, in quantum materials.

description: ESG, a framework to consider and evaluate companies and investments, has become something of a major development within the financial industry in the past five years. Two major financial regions of the world that have similar financial innovations and adopt similar practices, the United States and the European Union, have adopted and integrated ESG investing to varying degrees. In fact, the EU ESG market is substantially larger, more regulated, less controversial, and more common than the US ESG market. The first task of this paper is to examine the sizes and demand for the respective ESG markets of the EU and the US. Secondly, to evaluate the belief and perspectives in climate change that individuals in the EU and the US have. Next, I will discuss the factors of determination that impact climate change belief and further analyze how they could affect integration of ESG within the EU and the US. The last task of the paper is to evaluate the regulatory or legal distinctions that allow for ESG integration to increase among the general public and/or institutions. I will then provide a conclusion that talks about the importance of minimizing factors that could limit ESG investing development within the EU and the U.S.

description: Twenty-first century museums are moving away from the concept of neutrality and self- consciously heading towards more socially informed practices. However, racially sensitive and community-oriented frameworks have existed in ethnic museums for decades. The Wing Luke Museum in Seattle, Japanese American National Museum in Los Angeles, and Museum of Chinese in America in New York were founded in the post- Civil Rights Era by Asian American museum professionals to address and combat anti- Asian racism and to preserve the histories of Asian American communities. These museums responded to a modern moment of diasporic change and elevated the voices, stories, and everyday objects of Asian Americans. However, in the fifty years from when their doors opened until now, the neighborhoods and communities in which each museum was founded have transformed. This thesis will look at the politics of change and issues of representation at the above-mentioned Asian American museums that arose contemporaneously. The overarching question I explore is: how has each museum evolved through the twenty-first century? This thesis is situated in a larger body of scholarly work focused on revolutions in museum practices. Yet, my methodology also includes original research in the form of interviews and in-person observations. The culmination of this thesis shines a spotlight on three Asian American institutions that pioneered the kind of engagement work many other museums are attempting to replicate in 2023. This thesis offers a direct response to contemporary social, cultural, and geopolitical issues that are changing the landscape of community engagement pedagogy at three institutions that have always been at the forefront of the field. This work highlights the revolutionary histories of three radical Asian American institutions while simultaneously offering important critiques and considerations for how museums are and will continue to evolve in today’s cultural context.

description: We live in a dynamic retail environment. COVID forced retailers to adapt to new consumer behaviors quickly and develop robust omnichannel fulfillment infrastructures— meaning that online and offline channels had to be integrated. Today, e-commerce offerings are more robust than ever, and customers have more choices than ever regarding how they shop. Considering this dynamic environment, I have several questions about how retailers can persuade consumers, who became accustomed to e-commerce during the pandemic, to return to their stores. Furthermore, I am interested in evaluating retailers’ strategies to make their physical retail stores more appealing. Despite the growth of e-commerce and the ongoing pandemic, some American consumers expressed a desire to return to shopping in physical retail stores. According to a 2021 report, 57% of US adults “expressed excitement” to return to in-person shopping 1. Today’s retail environment is uncharted territory. Consumers have more channel options than ever before. Retailers have made significant changes because of the pandemic, which has rapidly accelerated digital transformation. My research examined whether customers who became accustomed to online shopping during the pandemic returned to physical retail stores. Through in-depth interviews with retail executives and managers, ethnographies, and a questionnaire, I sought to understand whether customers are returning to stores and to discern which strategies and decisions have been effective for persuading customers to return to stores and demonstrate loyalty towards a brand. My findings reveal that while some customers became accustomed to the convenience of online shopping, after realizing they could fulfill their needs without visiting stores, many customers longed to return to physical retail stores, and are shopping in stores, like how they behaved during the pandemic. My findings also revealed that consumers’ desires to visit stores vary by industry and shopping occasion. Additionally, many customers who use digital technology and e-commerce also value being able to visit the stores for returns, interact with merchandise, and seek out expert advice. While my questionnaire findings did not provide significant insights into how the pandemic changed behavior, they provide insight into how consumers choose between shopping online or in person for certain occasions. Ultimately, my findings provide a basis for further research on how retailing has changed because of the pandemic and omnichannel transformation.

description: Dijkgraaf-Witten theories are extended three-dimensional topological field theories of Turaev-Viro type. They can be constructed geometrically from categories of bundles via linearization. Boundaries and surface defects or interfaces in quantum field theories are of interest in various applications and provide structural insight. We perform a geometric study of boundary conditions and surface defects in Dijkgraaf-Witten theories. A crucial tool is the linearization of categories of relative bundles. We present the categories of generalized Wilson lines produced by such a linearization procedure. We establish that they agree with the Wilson line categories that are predicted by the general formalism for boundary conditions and surface defects in three-dimensional topological field theories that has been developed in arXive:1203.4568.

description: Long gamma-ray bursts (GRBs), which signify the end-life collapsing of very massive stars, are produced by extremely relativistic jets colliding into circumstellar medium. Huge energy is released both in the first few seconds, namely the internal dissipation phase that powers prompt emissions, and in the subsequent self-similar jet-deceleration phase that produces afterglows observed in broad-band electromagnetic spectrum. However, prompt optical emissions of GRBs have been rarely detected, seriously limiting our understanding of the transition between the two phases. Here we report detection of prompt optical emissions from a gamma-ray burst (i.e. GRB 201223A) using a dedicated telescope array with a high temporal resolution and a wide time coverage. The early phase coincident with prompt γ-ray emissions show a luminosity in great excess with respect to the extrapolation of γ-rays, while the later luminosity bump is consistent with onset of the afterglow. The clearly detected transition allows us to differentiate physical processes contributing to early optical emissions and to diagnose the composition of the jet

description: In this study, we have demonstrated the expansion history of an axially symmetric Bianchi type-I model of the universe. Our model as of now presents an accelerating universe, which had been in the decelerating phase in the past. Roles of the two crucial Hubble~$H(z)$ and deceleration~$q(z)$ parameters are examined. The energy parameters of the universe are estimated with the help of the latest observational Hubble data (46-data points) and Pantheon data (the latest compilation of SNIa with 40 binned in the redshift range $0.014 \leq z \leq 1.62)$. We also discuss the stability analysis of the model by state finder diagnosis. The analysis reveals that in late time, the model is a quintessence type and points towards the $Λ$CDM model. Our developed model agrees with observational findings in a proper way. We have discussed some of the physical aspects of the model.

Robust estimation of risks from small samples

description: Data-driven risk analysis involves the inference of probability distributions from measured or simulated data. In the case of a highly reliable system, such as the electricity grid, the amount of relevant data is often exceedingly limited, but the impact of estimation errors may be very large. This paper presents a robust nonparametric Bayesian method to infer possible underlying distributions. The method obtains rigorous error bounds even for small samples taken from ill-behaved distributions. The approach taken has a natural interpretation in terms of the intervals between ordered observations, where allocation of probability mass across intervals is well-specified, but the location of that mass within each interval is unconstrained. This formulation gives rise to a straightforward computational resampling method: Bayesian Interval Sampling. In a comparison with common alternative approaches, it is shown to satisfy strict error bounds even for ill-behaved distributions.

description: The educational success of Black girls in the United States is a critical issue that requires attention and action. This thesis examines the role of mentorship in supporting the educational outcomes of Black girls, drawing on existing literature in the field. Through a review of various studies, it becomes clear that mentorship programs that are grounded in critical race theory and feminism, and that prioritize the development of identity and empowerment, are most effective in promoting positive educational outcomes for Black girls. The thesis outlines key factors that are essential for successful mentorship programs, including the need for culturally responsive and trauma-informed practices, safe and inclusive spaces, and support for family and community engagement. It also identifies challenges that must be addressed in the implementation of these programs, such as funding, systemic racism, and the need for ongoing evaluation and assessment. The thesis recommends a structured approach to implementing effective mentorship programs, which includes the development of clear program goals and objectives, the recruitment of diverse and qualified mentors, the provision of training and support for mentors, and ongoing evaluation and assessment to ensure program effectiveness. It emphasizes the importance of centering the voices and experiences of Black girls in the design and implementation of these programs, and the need for a collaborative approach that involves families, communities, and schools. Overall, this thesis highlights the urgent need for action to support the educational success of Black girls, and emphasizes the critical role that mentorship can play in achieving this goal. By prioritizing the development of empowering and inclusive mentorship programs, we can help ensure that Black girls are able to thrive academically, socially, and personally.

description: Let $Q$ be a quiver, $M$ a representation of $Q$ with an ordered basis $\cB$ and $\ue$ a dimension vector for $Q$. In this note we extend the methods of \cite{L12} to establish Schubert decompositions of quiver Grassmannians $\Gr_\ue(M)$ into affine spaces to the ramified case, i.e.\ the canonical morphism $F:T\to Q$ from the coefficient quiver $T$ of $M$ w.r.t.\ $\cB$ is not necessarily unramified. In particular, we determine the Euler characteristic of $\Gr_\ue(M)$ as the number of \emph{extremal successor closed subsets of $T_0$}, which extends the results of Cerulli Irelli (\cite{Cerulli11}) and Haupt (\cite{Haupt12}) (under certain additional assumptions on $\cB$).

description: Wang-Landau simulations offer the possibility to integrate explicitly over a collective coordinate and stochastically over the remainder of configuration space. We propose to choose the so-called "slow mode", which is responsible for large autocorrelation times and thus critical slowing down, for collective integration. We study this proposal for the Ising model and the linear-log-relaxation (LLR) method as simulation algorithm. We firstly demonstrate super critical slowing down in a phase with spontaneously broken symmetry and for the heatbath algorithms, for which autocorrelation times grow exponentially with system size. By contrast, using the magnetisation as collective coordinate, we present evidence that super critical slowing down is absent. We still observe a polynomial increase of the autocorrelation time with volume (critical slowing down), which is however reduced by orders of magnitude when compared to local update techniques.
