description: This thesis explores the impact of the apparel return process on both a retailer’s economics and the environment. Given most shoppers consider the availability and ease of returns prior to purchasing from an apparel company, most retailers offer their customers “free” returns in some capacity. While consumers may not pay the retailer to initiate a return, there is still a cost associated with the return process, borne by the apparel company and the environment. Using an illustrative case study, this thesis analyzes existing financial and environmental data to illuminate the overall costs incurred by retailers and the environment due to the apparel return process. First, I explore the “average” return policy to understand the conditions under which returns are typically made. Then, I identify four main return scenarios based on the channel through which a customer initiates the return. Using secondary resources along with information gathered from local Austin apparel boutiques, I estimate the average dollar cost for a single return transaction within each scenario. To find the environmental cost, measured in carbon dioxide or carbon dioxide-equivalent emissions, I identify various combinations of return channels and destination. Using data from secondary sources, I ascribe an emission impact to each component of the return process. Finally, I calculate the total emissions from each combination for a single return, which I then convert to dollars to summarize the total average cost of a clothing return. I conclude with an estimate of the average cost of a clothing return, along with proposed actions retailers and/or consumers can take to decrease the total cost of clothing returns.

description: Infertility has been an issue throughout history, and yet there is very little research done on how it was approached and treated during historical times. There is even less research on how mental health and stigma around infertility can negatively impact those looking for treatment, especially women. This thesis investigates three forms of alternative medicine that have strong historical and cultural roots around the world. These are Traditional Chinese Medicine, Ayurvedic Medicine, and Indigenous Medicine. In addition, the mental health of infertility patients is analyzed, taking into account social and cultural factors. A selective literature review over these topics is conducted in addition to interviews of local alternative medicine practitioners in Austin, Texas. The purpose of this analysis is to detail the history and use of the three aforementioned alternative medicine methods in the context of infertility, and to explore how sociocultural perspectives on infertility affect patients’ mind states throughout treatment. Results confirm that there is little research on the efficacy and application of alternative medicine methods, yet general trends show a general success, especially when paired with treatments in the realm of conventional Western medicine. It can also be concluded that there is little to no existence of mental health support for women facing stigma and grief during infertility treatment. The study results suggest that further research on alternative medicines, implementing mental health support, and increasing positive and diverse perspectives on approaches to infertility will encourage more effective treatment for women who are trying to conceive.
A probabilistic solution to the Stroock-Williams equation

description: We consider the initial boundary value problem \begin{eqnarray*}u_t=μu_x+\tfrac{1}{2}u_{xx}\qquad (t>0,x\ge0),\\u(0,x)=f(x)\qquad (x\ge0),\\u_t(t,0)=νu_x(t,0)\qquad (t>0)\end{eqnarray*} of Stroock and Williams [Comm. Pure Appl. Math. 58 (2005) 1116-1148] where $μ,ν\in \mathbb{R}$ and the boundary condition is not of Feller's type when $ν<0$. We show that when $f$ belongs to $C_b^1$ with $f(\infty)=0$ then the following probabilistic representation of the solution is valid: \[u(t,x)=\mathsf{E}_x\bigl[f(X_t)\bigr]-\mathsf{E}_x\biggl[f'(X_t)\int_0^{\ell_t^0(X)}e^{-2(ν-μ)s}\,ds\biggr],\] where $X$ is a reflecting Brownian motion with drift $μ$ and $\ell^0(X)$ is the local time of $X$ at $0$. The solution can be interpreted in terms of $X$ and its creation in $0$ at rate proportional to $\ell^0(X)$. Invoking the law of $(X_t,\ell_t^0(X))$, this also yields a closed integral formula for $u$ expressed in terms of $μ$, $ν$ and $f$.

description: Black hair culture has been a significant element in shaping race relations in the United States. The spread of authentic black hair stories will help protect the collective black identity from false, racist ideals, which has been done by black artists for decades. Although black people have the backdrop of personal experience as a black woman with my own textured hair stories, many others lack that stimulant to want to interact with black hair. Non-black people often aren’t the ones seeking black stories or, if they do seek black stories, they may have limited access to them. The most authentic ones are those that come directly from black people. Throughout the past century, oppressors manipulated this limited visibility of the black community to rewrite narratives that black hair was unclean and therefore indicative of poverty. Such falsified stories about the black experience kept black people in lower social orders and, in some cases, even turned them against themselves. No matter what they did, they didn’t quite fit into their own stories because they weren’t the ones telling them. Today, in a desperate attempt to maintain sociopolitical stratification by race, oppressors still try to rewrite black people's stories when they feel threatened. Luckily, black representation in the arts has bolstered true black stories above those created by non-black groups. I explore hair and identity and is where I continue to find my own space to use my art as activism.
Wobbling kinks in a two-component scalar field theory: Interaction between shape modes

description: In this paper the interaction between the shape modes of the wobbling kinks arising in the family of two-component MSTB scalar field theory models is studied. The spectrum of the second order small kink fluctuation in this model has two localized vibrational modes associated to longitudinal and orthogonal fluctuations with respect to the kink orbit. It has been found that the excitation of the orthogonal shape mode immediately triggers the longitudinal one. In the first component channel the kink emits radiation with twice the orthogonal wobbling frequency (not the longitudinal one as happens in the $ϕ^4$-model). The radiation emitted in the second component has two dominant frequencies: one is three times the frequency of the orthogonal wobbling mode and the other is the sum of the frequencies of the longitudinal and orthogonal vibration modes. This feature is explained analytically using perturbation expansion theories.

Minimal faithful modules over Artinian rings

description: Let R be a left Artinian ring, and M a faithful left R-module which is minimal, in the sense that no proper submodule or proper homomorphic image of M is faithful. If R is local, and socle(R) is central in R, we show that length(M/J(R)M)+length(socle(M))$\leq$ length(socle(R))+1, strengthening a result of T. Gulliksen. Most of the rest of the paper is devoted to the situation where the Artinian ring R is not necessarily local, and does not necessarily have central socle. In the case where R is a finite-dimensional algebra over an algebraically closed field, we get an inequality similar to the above, with the length of socle(R) interpreted as its length as a bimodule, and with the final summand +1 replaced by the Euler characteristic of a bipartite graph determined by the structure of socle(R). More generally, that inequality holds if, rather than assuming k algebraically closed, we assume that R/J(R) is a direct product of full matrix algebras over k, and exclude the case where k has small finite cardinality. Examples show that the restriction on the cardinality of k is needed; we do not know whether versions of our result hold with other hypotheses significantly weakened. The situation for faithful modules with only one minimality property, i.e., having no faithful proper submodules or having no faithful proper homomorphic images, is more straightforward: The length of M/J(R)M in the former case, and of socle(M) in the latter, is $\leq$ length(socle(R)) (again meaning length as a bimodule). The final section, essentially independent of the rest of the note, obtains these bounds, and shows that every faithful module over a left Artinian ring has a faithful submodule with the former minimality condition and a faithful factor module with the latter. The proofs involve some nice general results on decompositions of modules.

description: Characterization of directly imaged exoplanets is one of the most eagerly anticipated science functions of the James Webb Space Telescope. MIRI, the mid-IR instrument has the capability to provide unique spatially resolved photometric data points in a spectral range never achieved so far for such objects. We aim to present the very first on-sky contrast measurements of the MIRI's coronagraphs. In addition to a classical Lyot coronagraph at the longest wavelength, this observing mode implements the concept of the four quadrant phase mask for the very first time in a space telescope. We observed single stars together with a series of reference stars to measure raw contrasts as they are delivered on the detector, as well as reference subtracted contrasts. MIRI's coronagraphs achieve raw contrasts greater than $10^3$ at the smallest angular separations (within $1''$) and about $10^5$ further out (beyond $5\sim6''$). Subtracting the residual diffracted light left unattenuated by the coronagraph has the potential to bring the final contrast down to the background and detector limited noise floor at most angular separations (a few times $10^4$ at less than $1''$). MIRI coronagraphs behave as expected from simulations. In particular the raw contrasts for all four coronagraphs are fully consistent with the diffractive model. Contrasts obtained with subtracting reference stars also meet expectations and are fully demonstrated for two four quadrant phase masks (F1065C and F1140C). The worst contrast, measured at F1550C, is very likely due to a variation of the phase aberrations at the primary mirror during the observations, and not an issue of the coronagraph itself. We did not perform reference star subtraction with the Lyot mask at F2300C, but we anticipate that it would bring the contrast down to the noise floor.

description: Several extensions of the Standard Model predict the production of dark matter particles at the LHC. A search for dark matter particles produced in association with a dark Higgs boson decaying into $W^{+}W^{-}$ in the $\ell^\pm\nu q \bar q'$ final states with $\ell=e,\mu$ is presented. This analysis uses 139 fb$^{-1}$ of $pp$ collisions recorded by the ATLAS detector at a centre-of-mass energy of 13 TeV. The $W^\pm \to q\bar q'$ decays are reconstructed from pairs of calorimeter-measured jets or from track-assisted reclustered jets, a technique aimed at resolving the dense topology from a pair of boosted quarks using jets in the calorimeter and tracking information. The observed data are found to agree with Standard Model predictions. Scenarios with dark Higgs boson masses ranging between 140 and 390 GeV are excluded.

description: In this paper, we consider the problem of distributed Bayesian detection in the presence of Byzantines in the network. It is assumed that a fraction of the nodes in the network are compromised and reprogrammed by an adversary to transmit false information to the fusion center (FC) to degrade detection performance. The problem of distributed detection is formulated as a binary hypothesis test at the FC based on 1-bit data sent by the sensors. The expression for minimum attacking power required by the Byzantines to blind the FC is obtained. More specifically, we show that above a certain fraction of Byzantine attackers in the network, the detection scheme becomes completely incapable of utilizing the sensor data for detection. We analyze the problem under different attacking scenarios and derive results for different non-asymptotic cases. It is found that existing asymptotics-based results do not hold under several non-asymptotic scenarios. When the fraction of Byzantines is not sufficient to blind the FC, we also provide closed form expressions for the optimal attacking strategies for the Byzantines that most degrade the detection performance.

description: We study graviton scattering on $AdS_4\times S^7$, which is dual to the stress tensor multiplet four-point function in the maximally supersymmetric 3d $U(N)_1\times U(N)_{-1}$ ABJM theory. We compute 1-loop corrections to this holographic correlator coming from Witten diagrams with supergravity $R$ and higher derivative $R^4$ vertices, up to contact term ambiguities, and find that the flat space limit matches the corresponding terms in the 11d M-theory S-matrix. We then use supersymmetric localization to show that all the 1-loop contact terms vanish, as was previously observed for the $AdS_4\times S^7/\mathbb{Z}_2$ theory dual to $U(N)_2\times U(N)_{-2}$ ABJM. Finally, we use the recent localization results of Gaiotto and Abajian, as inspired by twisted M-theory, to compute all the short OPE coefficients in correlators of the stress tensor multiplet and the next lowest half-BPS operator, which we find saturate the bootstrap bounds on these mixed correlators for all $N$.

We introduce an easily computed function f(t) for t > 0, determined by F, and we show that the strong maximum principle holds depending on whether the integral \int dy / f(y) near 0 is infinite or finite. This complements our previous work characterizing when the (ordinary) maximum principle holds. Along the way we characterize radial subsolutions.

description: Measurements of joint-polarisation states of $W$ and $Z$ gauge bosons in $W^{\pm}Z$ production are presented. The data set used corresponds to an integrated luminosity of $139$ fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of $13$ TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. The $W^{\pm}Z$ candidate events are reconstructed using leptonic decay modes of the gauge bosons into electrons and muons. The simultaneous pair-production of longitudinally polarised vector bosons is measured for the first time with a significance of $7.1$ standard deviations. The measured joint helicity fractions integrated over the fiducial region are $f_{\mathrm{00}} = 0.067 \pm 0.010$, $f_{\mathrm{0T}} = 0.110 \pm 0.029$, $f_{\mathrm{T0}} = 0.179 \pm 0.023$ and $f_{\mathrm{TT}} = 0.644 \pm 0.032$, in agreement with the next-to-leading-order Standard Model predictions. Individual helicity fractions of the $W$ and $Z$ bosons are also measured and found to be consistent with joint helicity fractions within the expected amount of correlations. Both the joint and individual helicity fractions are also measured separately in $W^+Z$ and $W^-Z$ events. Inclusive and differential cross sections for several kinematic observables sensitive to polarisation are presented.

This nonassociativity is controlled by the same Chevalley-Eilenberg cohomology that classifies free differential algebras, $p$-form generalizations of Cartan-Maurer equations. A possible relation with flux backgrounds of closed string theory is pointed out.

description: Three-body interactions can eject stars from the core of a globular cluster, causing them to enter the Galactic halo as extra-tidal stars. While finding extra-tidal stars is imperative for understanding cluster evolution, connecting isolated extra-tidal field stars back to their birth cluster is extremely difficult. In this work, we present a new methodology consisting of high-dimensional data analysis and a particle spray code to identify extra-tidal stars of any Galactic globular cluster using M3 as a case study. Using the t-Stochastic Neighbour Embedding (t-SNE) and Uniform Manifold Approximation and Projection (UMAP) machine learning dimensionality reduction algorithms, we first identify a set of 103 extra-tidal candidates in the APOGEE DR17 data catalogue with chemical abundances similar to M3 stars. To confirm each candidate's extra-tidal nature, we introduce corespray - a new Python-based three-body particle spray code that simulates extra-tidal stars for any Galactic globular cluster. Using Gaia EDR3 proper motions and APOGEE DR17 radial velocities, we apply multivariate Gaussian modelling and an extreme deconvolution to identify the extra-tidal candidates that are more likely to be associated with a distribution of corespray-simulated M3 extra-tidal stars than the field. Through these methods, we identify 10 new high-probability extra-tidal stars produced via three-body interactions in M3. We also explore whether any of our extra-tidal candidates are consistent with being ejected from M3 through different dynamical processes. Future applications of corespray will yield better understandings of core dynamics, star formation histories and binary fractions in globular clusters.

In this note, we prove their conjecture and slightly more. The proof relies on some symmetries of the ring of symmetric functions discovered by Koike and Terada. Using results of Hernandez, Mukhin-Young, and Naoi, this implies that the characters of minimal affinizations in types B, C, and D are given by a Jacobi-Trudi determinant.

description: A search for supersymmetry involving the pair production of gluinos decaying via off-shell third-generation squarks into the lightest neutralino ($\tilde\chi^0_1$) is reported. It exploits LHC proton$-$proton collision data at a centre-of-mass energy $\sqrt{s} = 13$ TeV with an integrated luminosity of 139 fb$^{-1}$ collected with the ATLAS detector from 2015 to 2018. The search uses events containing large missing transverse momentum, up to one electron or muon, and several energetic jets, at least three of which must be identified as containing $b$-hadrons. Both a simple kinematic event selection and an event selection based upon a deep neural-network are used. No significant excess above the predicted background is found. In simplified models involving the pair production of gluinos that decay via off-shell top (bottom) squarks, gluino masses less than 2.44 TeV (2.35 TeV) are excluded at 95% CL for a massless $\tilde\chi^0_1$. Limits are also set on the gluino mass in models with variable branching ratios for gluino decays to $b\bar{b}\tilde\chi^0_1$, $t\bar{t}\tilde\chi^0_1$ and $t\bar{b}\tilde\chi^-_1$ / $\bar{t}b\tilde\chi^+_1$.

description: Many intracellular processes continue to oscillate during the cell cycle. Although it is not well-understood how they are affected by discontinuities in the cellular environment, the general assumption is that oscillations remain robust provided the period of cell divisions is much larger than the period of the oscillator. Here, I will show that under these conditions a cell will in fact have to correct for an additional quantity added to the phase of oscillation upon every repetition of the cell cycle. The resulting phase shift is an analogue of the geometric phase, a curious entity first discovered in quantum mechanics. In this Letter, I will discuss the theory of the geometric phase shift and demonstrate its relevance to biological oscillations.

description: We report CrISe monolayer as a room temperature ferromagnetic semiconductor with the Curie temperature ($T_C$), magnetic anisotropy energy (MAE) and band gap being 322 K, 113 $μ$eV and 0.67 eV, respectively. The $T_C$ and MAE can be further enhanced up to 385 K and 313 $μ$eV by tensile strain. More interestingly, the magnetic easy axis can be switched between off-plane and in-plane by compressive strain. Particularly, due to the broken inversion symmetry and strong spin-orbit coupling of Se atoms, a large Dzyaloshinskii-Moriya interaction (DMI) of 2.40 meV is obtained. More importantly, by micromagnetic simulations, stable skyrmions with sub-10 nm radius are stabilized by the large DMI above room temperature in a wide range of strain from $-2\%$ to $6\%$. Our work demonstrates CrISe as a promising candidate for next-generation skyrmion-based information storage devices and provides guidance for the research of DMI and skyrmions in room temperature ferromagnetic semiconductors.

Jacobian algebras with periodic module category and exponential growth

description: The Jacobian algebra associated to a triangulation of a closed surface $S$ with a collection of marked points $M$ is (weakly) symmetric and tame. We show that for these algebras the Auslander-Reiten translate acts 2-periodical on objects. Moreover, we show that excluding only the case of a sphere with $4$ (or less) punctures, these algebras are of exponential growth. These four properties implies that there is a new family of algebras symmetric, tame and with periodic module category. As a consequence of the 2-periodical actions of the Auslander-Reiten translate on objects, we have that the Auslander-Reiten quiver of the generalized cluster category $\cC_{(S,M)}$ consists only of stable tubes of rank $1$ or $2$.
description: In the previous version I showed that the Jacobian algebras of closed surfaces, excluding the case of the sphere with 4 and 5 punctures, are algebras of exponential growth and it was changed grammar errors. In this new version I change the name of this note and I show that the Jacobian algebras of the sphere with 5 punctures are algebras of exponential growth. This is the final version

description: We show that an exact Lagrangian cobordism $L\subset \mathbb R \times P \times \mathbb R$ from a Legendrian submanifold $Λ\subset P\times \mathbb R$ to itself satisfies $H_i(L;\mathbb F)=H_i(Λ;\mathbb F)$ for any field $\mathbb F$ in the case when $Λ$ admits a spin exact Lagrangian filling and the concatenation of any spin exact Lagrangian filling of $Λ$ and $L$ is also spin. The main tool used is Seidel's isomorphism in wrapped Floer homology. In contrast to that, for loose Legendrian submanifolds of $\mathbb{C}^n \times \mathbb R$, we construct examples of such cobordisms whose homology groups have arbitrary high ranks. In addition, we prove that the front $S^m$-spinning construction preserves looseness, which implies certain forgetfulness properties of it.

description: Die neuen Medien sind schnell ein wesentlicher Bestandteil der modernen Kommunikation in der Archäologie geworden. Diese Tatsache ist bislang nur selten theoretisch beleuchtet worden, und die neuen Instrumente werden meist ohne ein tiefergehendes Verständnis der historischen Zusammenhänge archäologischen Kommunizierens genutzt. Der Autor entwirft eine erste und unvermeidbar noch grobe Skizze dieses Zusammenhangs. Damit verbunden ist die Thematisierung des Konflikts zwischen disziplinärer Exklusivität und einer Demokratisierung von Wissen. Es wird versucht, einen Rahmen abzustecken für künftige tiefergehende Debatten. Aus Sicht des Autors haben Archäologen noch zu oft eine hierarchische Haltung bei ihrer Beziehung zu Anderen, und dies wird sich ändern müssen. Zudem muss die Natur der neuen Medien hinterfragt werden: inwieweit sind sie selbst demokratisierende Faktoren? Wir brauchen ein besseres Verständnis unserer Publikumsgruppen und der Frage, was diese Gruppen von der Archäologie erwarten. Ein solches tieferes Verständnis erzeugt mehr gegenseitigen Respekt und mehr Bereitschaft, in einen produktiven Dialog einzutreten. Damit dies geschehen kann, muss das Feld des Diskurses und der richtigen Fragen abgesteckt werden. Einige dieser Fragen werden am Ende des Betrags beleuchtet.
description: New digital media are rapidly becoming an essential part of modern communications in archaeology. This is seldom theorised, and is being used without much understanding of the historical context of archaeological communications. The author provides an initial and inevitably basis scheme for such a context. This is linked to the notion of conflict between disciplinary exclusivity and the democratisation of knowledge. It is an attempt to establish parameters for future debate and discussion. The author’s position is that archaeologists too often have a hierarchical view of their relationship to others, and this needs to change. There are also questions about the nature of modern digital media and how far they are themselves democratising agents. We need a greater understanding of our audiences, and what these audiences want from us. With greater understanding will come greater respect and a greater willingness to engage in productive dialogue. To enable this to happen, we need to begin framing the right questions to ask. Some of these are highlighted at the end of the article.

description: An integer n is said to be y-friable if its largest prime factor $P^+(n)$ is less than y. In this paper, it is shown that the y-friable integers less than x have a weak exponent of distribution at least $3/5-\varepsilon$ when $(\log x)^c\leq y\leq x^{1/c}$ for some $c=c(\varepsilon)\geq 1$, that is, they are well distributed in the residue classes of a fixed integer $a$, on average over moduli $\leq x^{3/5-\varepsilon}$ for each fixed $a\neq 0$ and $\varepsilon>0$. We present an application to the estimation of the sum $\sum_{2\leq n\leq x, P^+(n)\leq y}τ(n-1)$ when $(\log x)^c\leq y$. This follows and improves on previous work of Fouvry and Tenenbaum. Our proof combines the dispersion method of Linnik in the setting of Bombieri, Fouvry, Friedlander and Iwaniec, and recent work of Harper on friable integers in arithmetic progressions.

description: Ziel des LAMB-Projektes ist es, Schüler darin zu unterstützen, im Klassenzimmer erworbenes Wissen über die lokale Kulturlandschaft nach draußen in ihre aktuelle Umgebung mitzunehmen. Das Verknüpfen wissenschaftlicher Erkenntnisse mit Hilfe von GPS und mobilen Technologien stimuliert an technischen Spielereien interessierte Schüler, die realen Landschaften zu erkunden. Mobile Anwendungen sind besonders bei archäologischen Stätten nützlich, von denen man nur wenig sehen kann oder welche die Wahrnehmung und Interpretation langfristiger Veränderungen in der Umwelt erfordern, um ihre Bedeutung zu verstehen. LAMB vermittelt gleichzeitig verschiedene standortbezogene Informationen, wie z. B. Karten, Bilder oder Texte, sobald die entsprechenden GPS-Koordinaten empfangen werden. Es ermöglicht zudem die Visualisierung von Landhebungsprozessen mit Hife von Höhenlinien, thematischen Karten oder rekonstruierten Küstenlinien. Die Verwendung von technologisch anspruchsvollen Materialien in der Schulbildung entwickelt die Forschungskompetenz der Schüler und verbessert ihre Möglichkeiten, sich selbständig zusätzliches Wissen anzueignen. Auf Grundlage unserer Studie zeigen wir, daß LAMB die Möglichkeiten von Schülern verbessert, ihre lokalen Kulturlandschaft zu erkunden und sich mit ihr zu identifizieren. Das pädagogische Modell von LAMB verbessert die Fertigkeit der Schüler, sowohl die Interaktion zwischen Menschen und ihrer sich verändernden Umwelt wahrzunehmen als auch den menschlichen Einfluss auf die Landschaft zu verstehen.
description: The objective of the LAMB project is to link knowledge gained in the classroom to the local cultural landscape by taking education out into the actual environment. Mediating scientific knowledge with GPS and mobile technology encourages gadget- oriented pupils to explore real landscapes. Mobile applications are especially useful in archaeological sites which have only a few visible elements, or which require perceiving and interpreting the long-term changes in the environment in order to understand their meaning. LAMB presents simultaneously different location-based materials, such as maps, pictures and text when receiving targeted GPS coordinates. It also enables visualization of the land uplift process via contour lines and thematic maps or reproduced shorelines. Utilizing technologically sophisticated materials in school education develops the research skills of the pupils and enhances their possibilities to acquire additional knowledge independently.
Based on this study, we argue that LAMB enhances pupils’ possibilities to explore their local cultural landscape and to identify themselves within it. We also argue that the pedagogical model of LAMB enhances pupils’ skills to understand both the interaction between people and their changing environment and the human impact on the landscape.

description: Challenges and opportunities of physics education in the covid-19 pandemic era  in West Java Indonesia By: Arip Nurahman Department of Physics Education, Indonesian Institute of Education aripnurahman@institutpendidikan.ac.id Abstract: The Covid-19 pandemic has significantly impacted the education sector worldwide, including physics education. This study aims to explore the challenges and opportunities of physics education in the Covid-19 pandemic era in West Java, Indonesia. A comprehensive literature review was conducted using a combination of keyword and database searches to identify relevant studies. The review found that the pandemic has posed several challenges to physics education, such as access to technology, transitioning to online learning, student engagement and motivation, and teacher training. However, the pandemic has also presented opportunities, such as the use of multimedia resources, greater flexibility in learning, and collaboration and innovation. The study highlights the need for effective teaching methods, such as multimedia resources and virtual experiments, to overcome the challenges posed by the pandemic. Addressing the challenges of access to technology and internet connectivity and providing sufficient training for physics teachers is crucial for ensuring effective physics education in the pandemic era. The findings of this research provide insights into the strategies that can be adopted to address the challenges and leverage the opportunities of physics education in the Covid-19 pandemic era in West Java, Indonesia. Keywords: Physics education, Covid-19 pandemic, West Java, Indonesia, challenges, opportunities, online learning, multimedia resources, teacher training, student engagement.
Stuck walks: A conjecture of Erschler, Tóth and Werner

Subjects: subject: Probability (math.PR)

description: In this paper, we work on a class of self-interacting nearest neighbor random walks, introduced in [Probab. Theory Related Fields 154 (2012) 149-163], for which there is competition between repulsion of neighboring edges and attraction of next-to-neighboring edges. Erschler, Tóth and Werner proved in [Probab. Theory Related Fields 154 (2012) 149-163] that, for any $L\ge1$, if the parameter $α$ belongs to a certain interval $(α_{L+1},α_L)$, then such random walks localize on $L+2$ sites with positive probability. They also conjectured that this is the almost sure behavior. We prove this conjecture partially, stating that the walk localizes on $L+2$ or $L+3$ sites almost surely, under the same assumptions. We also prove that, if $α\in(1,+\infty)=(α_2,α_1)$, then the walk localizes a.s. on $3$ sites.

description: We performed 3-D simulations of proton-rich material entrainment into \czw-rich He-shell flash convection and the subsequent H-ingestion flash that took place in the post-AGB star Sakurai's object. Observations of the transient nature and anomalous abundance features are available to validate our method and assumptions, with the aim to apply them to very low metallicity stars in the future. We include nuclear energy feedback from H burning and cover the full $4π$ geometry of the shell. Runs on $768^3$ and $1536^3$ grids agree well with each other and have been followed for $1500\mathrm{min}$ and $1200\mathrm{min}$. After a $850\mathrm{min}$ long quiescent entrainment phase the simulations enter into a global non-spherical oscillation that is launched and sustained by individual ignition events of H-rich fluid pockets. Fast circumferential flows collide at the antipode and cause the formation and localized ignition of the next H-overabundant pocket. The cycle repeats for more than a dozen times while its amplitude decreases. During the global oscillation the entrainment rate increases temporarily by a factor $\approx 100$. Entrained entropy quenches convective motions in the upper layer until the burning of entrained H establishes a separate convection zone. The lower-resolution run hints at the possibility that another global oscillation, perhaps even more violent will follow. The location of the H-burning convection zone agrees with a 1-D model in which the mixing efficiency is calibrated to reproduce the light curve. The simulations have been performed at the NSF Blue Waters supercomputer at NCSA.

description: Sub-project 4.2 deals with, first, the detection of textual congruencies in ancient texts and second, the determination of those congruencies that can be considered as being the origin or continuation of traditions. We have focussed in particular on references to one of the most influential texts of the time, which was Plato's Timaeus. The goal is to provide the complete indirect tradition of a Platonic work spanning a considerable period. The technical and philological considerations in determining a special type of text passage are briefly described in this paper. This special type of text passage can be found automatically
and is considered indirect tradition. The results of this manner of proceeding for an analysis of the Timaeus and other texts are then demonstrated. One example for working with the "CitationGraph" is shown in some detail.
