description: This thesis examines American expatriate teachers working in the People‘s Republic of China. Principally, it examines the various methods by which, and places in which, teachers create, maintain, and transgress boundaries, both physical and cultural. Based on participant observation and semi-structured interviews, the thesis focuses on boundaries in both the public and private spheres, such as large-scale social events, everyday routines and places, and the homes in which teachers live. These boundaries exist not only between expatriate teachers and local Chinese, but also between expatriate teachers and other expatriates. The multiplicity of boundaries that the teachers in China must negotiate suggests a need for a refuge, a physical and emotional place in which they may relax. That refuge is most closely linked to the idea of ―home,‖ in both its physical and cultural senses. But it is difficult for the teachers to fully create or recreate such a home due to their deterritorialization and the fragmentation (or at least multiplicity) of their identities. Since it may be impossible to fully reassemble the home once people leave their countries of origin, the idea of a transnational life may seem appropriate. But even here, the teachers face difficulties since the technologies that permit time-space compression are powerless in the face of the half-day time difference between China and North America.

description: Summary: This note briefly reviews certain aspects of the philosophy of Paulo Freire and relates them to the instructional methodology of simulation/gaming. The author attempts to show how simulation/games can be used to support many of Freire's concepts by promoting a student-educator relationship based upon mutuality, by placing emphasis on complex social reality as the legitimate content of education, and by increasing the student's opportunity to participate actively in the learning process.
FaaSter Troubleshooting -- Evaluating Distributed Tracing Approaches for Serverless Applications

description: Serverless applications can be particularly difficult to troubleshoot, as these applications are often composed of various managed and partly managed services. Faults are often unpredictable and can occur at multiple points, even in simple compositions. Each additional function or service in a serverless composition introduces a new possible fault source and a new layer to obfuscate faults. Currently, serverless platforms offer only limited support for identifying runtime faults. Developers looking to observe their serverless compositions often have to rely on scattered logs and ambiguous error messages to pinpoint root causes. In this paper, we investigate the use of distributed tracing for improving the observability of faults in serverless applications. To this end, we first introduce a model for characterizing fault observability, then provide a prototypical tracing implementation - specifically, a developer-driven and a platform-supported tracing approach. We compare both approaches with our model, measure associated trade-offs (execution latency, resource utilization), and contribute new insights for troubleshooting serverless compositions.

Subjects: subject: Kaldor, Economic Policies, Inflation
subject: B31, E61, E52

description: The article analyses Kaldor’s ideas on economic policy, his interest in policy issues, and his contribution on specific policies. It underlines Kaldor’s strong and cogent views on three main topics: monetary and fiscal policy, the control of cost inflation, and the stabilisation of commodity prices. The author suggests how Kaldor might have reacted to the most important economic policy questions that still face Britain and the European Union, thirty years after his death. Kaldor was a prominent opponent of Britain’s entry into the then Common Market in the 1970s: not on the basis of any emotive English nationalism, but rather because he believed that the British economy would be damaged by an exposure to unlimited competition from more successful European industries. Perhaps he would have argued that, by 2016, the damage has already been done, and that Britain should now remain in the Union to continue the fight for more sensible macroeconomic policies. He would certainly have been pleased that his adoptive country had refused to join the Eurozone.

description: The Caccetta-Häggkvist conjecture (denoted below CHC) states that the directed girth (the smallest length of a directed cycle) $dgirth(D)$ of a directed graph $D$ on $n$ vertices is at most $\lceil \frac{n}{δ^+(D)}\rceil$, where $δ^+(D)$ is the minimum out-degree of~$D$. We consider a version involving all out-degrees, not merely the minimum one, and prove that if $D$ does not contain a sink, then $dgirth(D) \le 2 \sum_{v\in V(D)} \frac{1}{deg^+(v)+1}$. In the spirit of a generalization of the CHC to rainbow cycles in \cite{ADH2019}, this suggests the conjecture that given non-empty sets $F_1, \ldots,F_n$ of edges of $K_n$, there exists a rainbow cycle of length at most $2\sum_{1\le i \le n}\frac{1}{|F_i|+1}$. We prove a bit stronger result when $1\le |F_i|\le 2$, thereby strengthening a result of DeVos et. al \cite{DDFGGHMM2021}. We prove a logarithmic bound on the rainbow girth in the case that the sets $F_i$ are triangles.

description: Feedback optimization is a control paradigm that enables physical systems to autonomously reach efficient operating points. Its central idea is to interconnect optimization iterations in closed-loop with the physical plant. Since iterative gradient-based methods are extensively used to achieve optimality, feedback optimization controllers typically require the knowledge of the steady-state sensitivity of the plant, which may not be easily accessible in some applications. In contrast, in this paper, we develop a model-free feedback controller for efficient steady-state operation of general dynamical systems. The proposed design consists of updating control inputs via gradient estimates constructed from evaluations of the nonconvex objective at the current input and at the measured output. We study the dynamic interconnection of the proposed iterative controller with a stable nonlinear discrete-time plant. For this setup, we characterize the optimality and stability of the closed-loop behavior as functions of the problem dimension, the number of iterations, and the rate of convergence of the physical plant. To handle general constraints that affect multiple inputs, we enhance the controller with Frank-Wolfe-type updates.

description: Natural Language Generation (NLG) has improved exponentially in recent years thanks to the development of sequence-to-sequence deep learning technologies such as Transformer-based language models. This advancement has led to more fluent and coherent NLG, leading to improved development in downstream tasks such as abstractive summarization, dialogue generation and data-to-text generation. However, it is also apparent that deep learning based generation is prone to hallucinate unintended text, which degrades the system performance and fails to meet user expectations in many real-world scenarios. To address this issue, many studies have been presented in measuring and mitigating hallucinated texts, but these have never been reviewed in a comprehensive manner before. In this survey, we thus provide a broad overview of the research progress and challenges in the hallucination problem in NLG. The survey is organized into two parts: (1) a general overview of metrics, mitigation methods, and future directions; (2) an overview of task-specific research progress on hallucinations in the following downstream tasks, namely abstractive summarization, dialogue generation, generative question answering, data-to-text generation, machine translation, and visual-language generation; and (3) hallucinations in large language models (LLMs). This survey serves to facilitate collaborative efforts among researchers in tackling the challenge of hallucinated texts in NLG.

description: In recent years, reinforcement learning (RL) has acquired a prominent position in health-related sequential decision-making problems, gaining traction as a valuable tool for delivering adaptive interventions (AIs). However, in part due to a poor synergy between the methodological and the applied communities, its real-life application is still limited and its potential is still to be realized. To address this gap, our work provides the first unified technical survey on RL methods, complemented with case studies, for constructing various types of AIs in healthcare. In particular, using the common methodological umbrella of RL, we bridge two seemingly different AI domains, dynamic treatment regimes and just-in-time adaptive interventions in mobile health, highlighting similarities and differences between them and discussing the implications of using RL. Open problems and considerations for future research directions are outlined. Finally, we leverage our experience in designing case studies in both areas to showcase the significant collaborative opportunities between statistical, RL, and healthcare researchers in advancing AIs.

description: In this paper we study robust output tracking and disturbance rejection of linear partial differential equation (PDE) models. We focus on demonstrating how the abstract internal model based controller design methods developed for "regular linear systems" can be utilised in controller design for concrete PDE systems. We show that when implemented for PDE systems, the abstract control design methods lead in a natural way to controllers with "PDE parts". Moreover, we formulate the controller construction in a way which utilises minimal knowledge of the abstract system representation and is instead solely based on natural properties of the original PDE. We also discuss computation and approximation of the controller parameters, and illustrate the results with an example on control design for a boundary controlled diffusion equation.

subject: F35; F65; G01; G28

description: The evolution of the EU supervisory architecture has demonstrated that it took the risk of a euro break-up to barely overcome the Member States and their supervisors’ political resistances to centralisation. In the two-tier Europe that is emerging after the euro crisis, the integrity of the single market seems today crucially interlinked with the success of the banking union and its attractiveness for non-euro countries. The banking union’s design, without a credible common fiscal backstop, remains however a partial solution to the financial stability issues arising from the fragmentation of the EU financial market in the event of banking crises. Against this background, this work performs an analysis on non-euro countries’ own assessments of the pros and cons of joining the banking union. The analysis aims at showing that until fiscal responsibility for financial stability remains at the national level, regulatory centralisation cannot sever the traditional divide between home and host supervisors.

description: The applications of machine learning algorithms are innumerable and cover nearly every domain of modern technology. During this rapid growth of this area, more and more companies have expressed a desire to utilize machine learning techniques in smaller devices, such as cell phones or smart Internet of Things (IoT) instruments. However, as machine learning has so far required a power source with more capacity and higher efficiency than a conventional battery. Therefore, introducing neural network accelerators with low energy demands and low latency for executing machine learning techniques has drawn lots of attention in both the academia and industry.

Whereas by the valence formula the (weighted) number of zeros of this modular form in $γ\mathcal{F}$ is a constant only depending on its weight, we give a closed formula for this number of critical points in terms of those zeros of the modular form lying on the boundary of $\mathcal{F},$ the value of $γ^{-1}(\infty)$ and the weight. More generally, we indicate what can be said about the number of zeros of a quasimodular form.

description: The most complicated and challenging system within a light-pulse atom interferometer (LPAI) is the laser system, which controls the frequencies and intensities of multiple laser beams over time to configure quantum gravity and inertial sensors. The main function of an LPAI laser system is to perform cold-atom generation, state-preparation, state-selective detection and to generate coherent two-photon process for the light-pulse sequence. Substantial miniaturization and ruggedization of the laser system can be achieved by bringing most key functions of the laser system onto photonic integrated circuit (PIC). We demonstrate a high-performance silicon photonic suppressed-carrier single-sideband (SC-SSB) modulator at 1560 nm, which can dynamically frequency shift within the LPAI. With independent RF-channel control, we study the imbalances in both the optical and RF phases/amplitudes to reach 30 dB carrier-suppression, unprecedented 47.8 dB sideband-suppression at peak conversion-efficiency: -6.846 dB (20.7 %). Using a silicon photonic SSB-modulator, we demonstrate cold-atom generation, state-selective detection, and atom interferometer fringes to estimate gravitational acceleration, $g \approx 9.77 \pm 0.01 \,\rm{m/s^2}$, in a Rubidium ($^{87}$Rb) atom system.

description: The bulk of economic studies on income distribution focus on the poor and/or on the rich, mostly ignoring those who fall between these two categories. Research on the polarisation of incomes reverses this perspective, considering the middle-income group as a crucial element of analysis. The exploration of the income dynamics of the middle-income group is particularly relevant in the case of Italy. There, it has helped explaining the gap between the empirical evidence of stability in the main distributional indices and the worsening of confidence and expectations among Italian households since the 2000s, already before the crisis. This paper investigates the drivers of mobility of the middle-income group in Italy during the recent recession, with the aim of assessing the changes in the vulnerability of this group to downward mobility. Our findings reveal a general impoverishment of the middle-income group due to the recession and highlight an increasing rigidity of the Italian social structure. Lower entry and exit rates between groups emerge after 2008, possibly due to a growing weakness of the welfare state and the increasing inability of families to cope with unforeseen financial difficulties.

Robust inference for matching under rolling enrollment

Year: 2022
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: Matching in observational studies faces complications when units enroll in treatment on a rolling basis. While each treated unit has a specific time of entry into the study, control units each have many possible comparison, or "pseudo-treatment," times. The recent GroupMatch framework (Pimentel et al., 2020) solves this problem by searching over all possible pseudo-treatment times for each control and selecting those permitting the closest matches based on covariate histories. However, valid methods of inference have been described only for special cases of the general GroupMatch design, and these rely on strong assumptions. We provide three important innovations to address these problems. First, we introduce a new design, GroupMatch with instance replacement, that allows additional flexibility in control selection and proves more amenable to analysis. Second, we propose a block bootstrap approach for inference in GroupMatch with instance replacement and demonstrate that it accounts properly for complex correlations across matched sets. Third, we develop a permutation-based falsification test to detect possible violations of the important timepoint agnosticism assumption underpinning GroupMatch, which requires homogeneity of potential outcome means across time. Via simulation and a case study of the impact of short-term injuries on batting performance in major league baseball, we demonstrate the effectiveness of our methods for data analysis in practice.

description: The article provides a review of Sylos Labini’s memories, collected here on occasion of the tenth anniversary of his passing away. The author reports on the proceedings of two conferences in memory of Sylos Labini held in Rome, on 18 November 2015 at the Lincean Academy and on 4 December 2015 at Sapienza University. Sylos Labini stipulated that the goal of economic development is not just to satisfy human needs, but to cater civil development itself, in accordance with Adam Smith’s fundamental lesson. In his view, economic development and civil development interact in a circular manner in the long run. Considering the developmental issues of Italy’s Mezzogiorno, Sylos Labini highlights that the nature of the problem is not only economic, but rather many issues arise from unreasonable links between politics, economy, and society. Accordingly, he provided policy suggestions that are not limited to the economic and industrial fields (such as water supply projects, irrigation infrastructures, and investments for the creation of modern industries), but he also identified three priority areas of social policy: measures to contrast the mafias, crime in public procurement, and corruption; a reform of the public administration; and investments in education, universities, and research.

description: The Goertler instability of the laminar compressible boundary layer flows along concave surfaces is investigated. The linearized disturbance equations for the three-dimensional, counter-rotating streamwise vortices in two dimensional boundary layers are presented in an orthogonal curvilinear coordinates. The basic approximation of the disturbance equations, that includes the effect of the growth of the boundary layer, is considered and solved numerically. The effect of compressibility on critical stability limits, growth rates, and amplitude ratios of the vortices is evaluated for a range of Mach numbers for Oto 5. The effect of wall cooling and suction of the boundary layer on the development of Goertler vortices is investigated for different Mach numbers.

description: Despite the significant progress that the United States and the USSR have made in cooperating to resolve regional conflicts, many of these conflicts continue. One reason for this is that the Soviet and American governments have had differing expectations regarding what the outcome of superpower conflict resolution efforts should be. Yet even when Soviet and American aims are similar, there are other obstacles to conflict resolution. Among these are the lack of commitment to democracy on the part of one or more of the local antagonists in regional conflicts, and involvement by other external parties in the conflicts. There is no guarantee that the superpowers can successfully resolve regional conflicts even if they adopt a common approach to conflict resolution, but adopting a common approach may at least allow Washington and Moscow to unlink their overall relations from those conflicts that cannot be resolved.

description: Die Versorgung pflegebedürftiger Menschen in ihrer eigenen Häuslichkeit ist ein aktuell wie zukünftig hochrelevantes Feld gesellschaftlich notwendiger Dienstleistungen. In der ambulanten Versorgung pflegebedürftiger Menschen werden haushaltsnahe Tätigkeiten und oft auch Betreuungsaufgaben durch Haushaltshilfen erbracht, die in der Regel keine spezifische formale Berufsqualifikation haben. Obgleich diese Beschäftigten eine gesellschaftlich wichtige Tätigkeit ausüben, die zugleich als besonders beanspruchend gilt, sind die konkreten psychosozialen Gesundheitsrisiken und -ressourcen dieser Beschäftigtengruppe kaum bekannt. Das von der BGW geförderte Projekt Psychosoziale Gesundheitsrisiken und -ressourcen im Bereich ambulanter haushaltsnaher Dienste (PsyGeRaH) widmet sich diesem Desiderat. Zur Identifikation von Gesundheitsrisiken und Ressourcen wurden Expert:inneninterviews, Fallstudien und ein Expert:innenworkshop durchgeführt und im Rahmen einer Triangulation integriert ausgewertet. Die Ergebnisse des Projekts zeigen, dass die Tätigkeit der haushaltsnahen Dienstleistung im Umfeld von Pflegebedürftigkeit eine Vielzahl von unterschiedlichen psychosozialen Risiken und Ressourcen aufweist, wobei speziell die Interaktionsarbeit mit den pflegebedürftigen Personen und ihrem Sorgenetzwerk als Tätigkeitsanforderung eine besondere Relevanz hat. Weiterhin zeigte sich, dass die Arbeit in Privathaushalten, gesundheitsorientierte Führung und Decent-Work-Kriterien zukünftig eine verstärkte Beachtung im Rahmen der Präventionsarbeit dieser Beschäftigtengruppe einnehmen sollten, damit Beschäftigte nachhaltig beschäftigungsfähig bleiben und gesundheitsorientiert häusliche Sorgenetzwerke entlasten können. Der Bericht schließt mit Handlungsempfehlungen, die sich sowohl an der Ressourcenentwicklung als auch der Reduzierung von Belastungen orientieren.

We solve the optimization problem classically and consider algorithmic tools to scale it to higher numbers of qubits. We investigate stochastic gradient descent and two sketch-and-solve algorithms. For all three algorithms, we compute the gradient efficiently using matrix-vector instead of matrix-matrix computations. Allowing for a runtime on the order of one hour, our implementation using either sketch-and-solve algorithm is able to compile 9 qubit, 27 CNOT circuits; 12 qubit, 24 CNOT circuits; and 15 qubit, 15 CNOT circuits. Without our algorithmic tools, standard optimization does not scale beyond 9 qubit, 9 CNOT circuits, and, beyond that, is theoretically dominated by barren plateaus.

description: We study harmonic and biharmonic maps from gradient Ricci solitons. We derive a number of analytic and geometric conditions under which harmonic maps are constant and which force biharmonic maps to be harmonic. In particular, we show that biharmonic maps of finite energy from the two-dimensional cigar soliton must be harmonic.

description: Previously, we demonstrated hysteretic and persistent changes of resistivity in two-terminal electronic devices based on charge trapping and detrapping at immobile metastable defects [H. Yin, A. Kumar, J.M. LeBeau, and R. Jaramillo, Phys. Rev. Applied 15, 014014 (2021)]; we termed these devices as defect-level switching (DLS) devices. DLS devices feature all-electronic resistive switching and thus are volatile because of the voltage-time dilemma. However, the dynamics of volatile resistive switches may be valuable for emerging applications such as selectors in crosspoint memory, and neuromorphic computing concepts. To design memory and computing circuits using these volatile resistive switches, accurate modeling is essential. In this work we develop an accurate and analytical model to describe the switching physics in DLS devices, based on the established theories of point defect metastability in Cu(In,Ga)Se2 (CIGS) and II-VI semiconductors. The analytical nature of our model allows for time-efficient simulations of dynamic behavior of DLS devices. We model the time durations of SET and RESET programming pulses, which can be exponentially shortened with respect to the pulse amplitude. We also demonstrate the concept of inverse design: given desired resistance states, the width and amplitude of the programming signal can be chosen accordingly.

description: We train a neural network model to predict the full phase space evolution of cosmological N-body simulations. Its success implies that the neural network model is accurately approximating the Green's function expansion that relates the initial conditions of the simulations to its outcome at later times in the deeply nonlinear regime. We test the accuracy of this approximation by assessing its performance on well understood simple cases that have either known exact solutions or well understood expansions. These scenarios include spherical configurations, isolated plane waves, and two interacting plane waves: initial conditions that are very different from the Gaussian random fields used for training. We find our model generalizes well to these well understood scenarios, demonstrating that the networks have inferred general physical principles and learned the nonlinear mode couplings from the complex, random Gaussian training data. These tests also provide a useful diagnostic for finding the model's strengths and weaknesses, and identifying strategies for model improvement. We also test the model on initial conditions that contain only transverse modes, a family of modes that differ not only in their phases but also in their evolution from the longitudinal growing modes used in the training set. When the network encounters these initial conditions that are orthogonal to the training set, the model fails completely. In addition to these simple configurations, we evaluate the model's predictions for the density, displacement, and momentum power spectra with standard initial conditions for N-body simulations. We compare these summary statistics against N-body results and an approximate, fast simulation method called COLA. Our model achieves percent level accuracy at nonlinear scales of $k\sim 1\ \mathrm{Mpc}^{-1}\, h$, representing a significant improvement over COLA.

The philosophy of integralism in the philosophy of Sri Aurobindo Ghose
Creators: name: Leyden, Michael J.
Publisher: name: Washington State University
Year: 1974
Subjects: Ghose, Aurobindo,--1872-1950

description: This thesis examines the “Philosophy of Integralism” in Sri Aurobindo Ghose's thought. The areas of metaphysics, epistemology and religion have been dealt with especially.
description: The first chapter indicates the object of the thesis, examines Sri Aurobindo's life, points out his significance as a philosopher and gives an initial statement of what “Integralism” means.
description: Chapter two presents the philosophic task Sri Aurobindo is faced with in constructing an “Integral Philosophy,” namely, the controversy between East and West over intuition and intellect.
description: The theory of “Integral Evolution” which is the basis for his comprehensive metaphysical synthesis is presented in chapter three.
description: A critical estimation of Sri Aurobindo's theory of “Integral Evolution” is given in chapter four. Here it is shown that the primary principles of ascent, descent, and integration of his theory while plausible, do have inherent difficulties when subjected to confirmation and experiential verification.
description: Chapter five is the conclusion and indicates what we take to be Sri Aurobindo's contribution to philosophy and the further need for integral philosophizing.
An evaluation of bone marrow-derived mesenchymal stem cells as a treatment for collagenase induced desmitis of the proximal suspensory ligament in horses
Creators: name: Marsh, Chad Aaron
Publisher: name: Washington State University

Subjects: Horses--Diseases--Treatment

description: Objective – To evaluate the use of bone marrow derived mesenchymal stem cells (BMdMSC) to evaluate healing of the proximal suspensory ligament in horses with collagenase-induced desmitis and determine how evidence of healing on MRI and ultrasonographic examinations correlates to histologic and biochemical healing of the suspensory ligament. Animals – 6 horses Procedures – Clinical and MRI examinations were performed to confirm that the suspensory ligament was normal. Autologous bone marrow was collected from the tuber coxae, mesenchymal stem cells were cultured, expanded, and frozen at -80° C. Desmitis of the proximal suspensory ligament was induced with collagenase in both hindlimbs of each horse. One randomly assigned limb in each horse was treated with autogenous bone marrow derived mesenchymal stem cells (BMdMSC’s) at 2 weeks post collagenase injection, and the opposite limb was not treated. All horses were placed into a 6 months rest and rehabilitation program. Lameness examinations were performed throughout the study to determine clinical response to treatment. Healing was evaluated by MRI and ultrasound examinations 28, 90, and 200 days following induction of desmitis. Horses were euthanized at 228 days. Biochemical analysis of soluble collagen, DNA, proteoglycan and collagen type I and III were performed. Gross and histologic evaluation of ligament structure, fiber alignment, and collagen typing were used to define ligament architecture. Results – Immunohistochemical and histologic evaluation revealed improvements in ligament architectural organization, reduction in type III collagen, increases in type I collagen, and improvements in alignment of collagen fibers and fiber density in BMdMSC treated ligaments. There was no difference in biochemical indices between the two groups. MRI and ultrasound results revealed improvement in quality and rate of repair in BMdMSC treated and control ligaments over the course of the study. Ultrasonography underestimated ligament size and lesion size initially compared to MRI; however, at the conclusion of the study ultrasonographic examinations significantly overestimated lesion size. Low signal on Proton Density (PD) MRI at the previous site of desmitis correlated with histologic healing and collagen fiber reorganization at the conclusion of the study. Conclusions and Clinical Relevance – Intralesional injection of BMdMSC improves healing of the suspensory ligament. Rest alone has been a mainstay of treatment; however, ligaments treated with rest and intralesional injection of BMdMSC were more structurally normal than ligaments treated with rest alone. Ultrasound significantly underestimates the severity of ligament damage following an acute injury. MRI is recommended to determine an accurate estimate of the severity of damage to the proximal suspensory ligament in the rear limbs of horses.
Scientific Inference With Interpretable Machine Learning: Analyzing Models to Learn About Real-World Phenomena

description: To learn about real world phenomena, scientists have traditionally used models with clearly interpretable elements. However, modern machine learning (ML) models, while powerful predictors, lack this direct elementwise interpretability (e.g. neural network weights). Interpretable machine learning (IML) offers a solution by analyzing models holistically to derive interpretations. Yet, current IML research is focused on auditing ML models rather than leveraging them for scientific inference. Our work bridges this gap, presenting a framework for designing IML methods-termed 'property descriptors' -- that illuminate not just the model, but also the phenomenon it represents. We demonstrate that property descriptors, grounded in statistical learning theory, can effectively reveal relevant properties of the joint probability distribution of the observational data. We identify existing IML methods suited for scientific inference and provide a guide for developing new descriptors with quantified epistemic uncertainty. Our framework empowers scientists to harness ML models for inference, and provides directions for future IML research to support scientific understanding.

description: We study entanglement negativity for evaporating black hole based on the holographic model with defect brane. We introduce a defect extremal surface formula for entanglement negativity. Based on partial reduction, we show the equivalence between defect extremal surface formula and island formula for entanglement negativity in AdS$_3$/BCFT$_2$. Extending the study to the model of eternal black hole plus CFT bath, we find that black hole-black hole negativity decreases until vanishing, left black hole-left radiation negativity is always a constant, radiation-radiation negativity increases and then saturates at a time later than Page time. In all the time dependent cases, defect extremal surface formula agrees with island formula.

We study models in which the internal disposition of magnetization is driven by a single parameter, that controls the topological charge density of the magnetic structure. In particular, we focus mainly on the configurational entropy of these skyrmions and half-skyrmions and show how to increase or diminish their informational capabilities.
