description: Motivated by the probabilistic methods for nonlinear differential equations introduced by McKean (1975) for the Kolmogorov-Petrovski-Piskunov (KPP) equation, and by Le Jan and Sznitman (1997) for the incompressible Navier-Stokes equations, we identify a new class of stochastic cascade models, referred to as Doubly Stochastic Yule cascades. We establish non-explosion criteria under the assumption that the randomization of Yule intensities from generation to generation is by an ergodic time-reversible Markov process. In addition to the cascade models that arise in the analysis of certain deterministic nonlinear differential equations, this model includes the multiplicative branching random walks, the branching Markov processes, and the stochastic generalizations of the percolation and/or cell aging models introduced by Aldous and Shields (1988) and independently by Athreya (1985).

description: Recycling of Lithium-ion battery cathode materials has become increasingly important due to the limited amount of resources of raw materials and the environmental and the economic benefit. Recently, a new process, direct recycling, has been gradually developed with less energy andcost input. For this process, the aged cathode materials directly react with a Lithium source under certain thermal process to refunctionalize the aged cathode. The process is also appealing in cases where there is a large amount of similar cathode materials in use, such as electric vehicles.In reality, Li-ion batteries go through many materials changes as they are charged and discharged. As a result of aging mechanism that can occur under different cycling conditions at different regions of the cell, aged cathode materials can differ in both bulk properties1, such asresidual Li content level, as well as surface properties, such as solid-state interface (SEI) and surface reconstruction layer. Because these differences exist in aged cathode materials, there is a likely inconsistency of recycled product unless these effects are understood and corrected.As such, the two primary objectives of this work are:1. Investigate relationship between the cycling conditions of 18650 Li-ion batteries and the state and consistency of the Li(NixCoyAlz)O2 (x+y+z=1) (NCA) materials in them after aging. 2. Investigate the relationships between aged NCA materials properties, and recycling processes,and the resulting products. To achieve the 1st objective, commercial 18650 cells were cycled under 4 different conditions. Full cell cycling data and post-mortem analysis of both electrode materials reveal that aged NCA materials show different properties after being tested under different cell cycling conditions. Moreover, inhomogeneity in electrode properties was observed and analyzed under certain cellcycling condition. Therefore, the differences in aged NCA materials properties, including the level of residual Li content, SEI thickness, surface reconstruction layer and etc, result from not only the cycling condition of the cell but also the inhomogeneous aging within one cell. To achieve the 2nd objective, solid-state recycling process parameters, including Lithium source, reactants ratio, calcination temperature, calcination time, graphite contamination content and etc, were investigated in order to understand the relationship between the aged NCA materialsproperties and process parameters. Optimized process steps were created to deal with difference in some of aged NCA materials properties based on the fundamental understanding of the relithiation steps.

description: Technology has substantially broadened the horizons of music practice, providing alternatives to conventional methods. Mobile apps and software with embedded lessons and real-time feedback deliver the convenience of a music teacher directly to smartphones, incorporating gamification elements that render practice sessions more immersive.The emergence of virtual reality and augmented reality technologies introduces new dimensions to music practice, offering immersive environments for learners to interact with musical instruments and compositions in innovative ways. This thesis introduces MR Keys, an innovative AR application for Microsoft HoloLens, aimed at revolutionizing piano learning. MR Keys provides engaging methods for both novice and advanced pianists to hone their skills, using a dynamic tile system where users interact with the app by playing piano keys as tiles descend upon them. Mistakes result in point deductions, motivating users to strive for perfection. MR Keys' AI integration is a standout feature, enabling the creation of complementary melodies when users play chord progressions. User feedback has been pivotal in evaluating the comparative advantages of practicing alongside AI, offering insights into areas for future refinement.

No-Go Theorems Face Background-based Theories for Quantum Mechanics

description: Recent experiments have shown that certain fluid-mechanical systems, namely oil droplets bouncing on oil films, can mimic a wide range of quantum phenomena, including double-slit interference, quantization of angular momentum and Zeeman splitting. Here I investigate what can be learned from these systems concerning no-go theorems as those of Bell and Kochen-Specker. In particular, a model for the Bell experiment is proposed that includes variables describing a 'background' field or medium. This field mimics the surface wave that accompanies the droplets in the fluid-mechanical experiments. It appears that quite generally such a model can violate the Bell inequality and reproduce the quantum statistics, even if it is based on local dynamics only. The reason is that measurement independence is not valid in such models. This opens the door for local 'background-based' theories, describing the interaction of particles and analyzers with a background field, to complete quantum mechanics. Experiments to test these ideas are also proposed.

description: Context: A Legacy system can be defined as a system that significantly resists modification and evolution. According to the literature, there are two main strategies to migrate a legacy system: (a) to replace the legacy system by a new one, (b) to incrementally migrate parts from the legacy system to the new one. Incremental migration allows developers to better control the risks that may occur during the migration process. However, this strategy is more complex because it requires decomposition of the legacy system into different parts, e.g. a set of files, and to define the order of migration of them along the migration process. To our knowledge, there is no approach to support developers on those activities. Objective: This paper presents an approach, named MigrationExp, to support incremental language migrations of applications from one source language to another target language. MigrationExp recommends the files that should be migrated first in a particular migration iteration. As a novelty, our approach relies on a ranking model learned, using a learning-to-rank algorithm, from migrations made by developers. Method: We validate our approach in the context of the migrations of Android apps, from Java to Kotlin, a new official language for Android. We train our model using migrations of Java code to Kotlin written by developers on open-source applications. Results: The results show that, on the task of proposing files to migrate, our approach outperforms a previous migration strategy proposed by Google, in terms of its ability to accurately predict empirically observed migration orders. Conclusion: Since most Android applications are written in Java, we conclude that approaches to support developers such as MigrationExp may significantly impact the development of Android applications.

description: We investigate the Loschmidt echo, the overlap of the initial and final wavefunctions of Luttinger liquids after a spatially inhomogeneous interaction quench. In studying the Luttinger model, we obtain an analytic solution of the bosonic Bogoliubov-de Gennes equations after quenching the interactions within a finite spatial region. As opposed to the power law temporal decay following a potential quench, the interaction quench in the Luttinger model leads to a finite, hardly time dependent overlap, therefore no orthogonality catastrophe occurs. The steady state value of the Loschmidt echo after a sudden inhomogeneous quench is the square of the respective adiabatic overlaps. Our results are checked and validated numerically on the XXZ Heisenberg chain.

description: Nonlinear heat transfer can be exploited to reveal novel transport phenomena and thus enhance peo-ple's ability to manipulate heat flux at will. However, there hasn't been a mature discipline called nonlinear thermotics like its counterpart in optics or acoustics to make a systematic summary of rele-vant researches. In the current review, we focus on recent progress in an important part of nonlinear heat transfer, i.e., tailoring nonlinear thermal devices and metamaterials under the Fourier's law, especially with temperature-dependent thermal conductivities. We will present the basic designing techniques including solving the equation directly and the transformation theory. Tuning nonlinearity coming from multi-physical effects, and how to calculate effective properties of nonlinear conductive composites using the effective medium theory are also included. Based on these theories, researchers have successfully designed various functional materials and devices such as the thermal diodes, thermal transistors, thermal memory elements, energy-free thermostats, and intelligent thermal materials, and some of them have also been realized in experiments. Further, these phenomenological works can provide a feasible route for the development of nonlinear thermotics.

description: Managing changes has become a critical issue in the construction industry in recent years. Changes are inevitable throughout the lifecycle of the construction project. Understanding change causes and effects can support project teams to manage changes proactively. Although various research articles are published in this field, a comprehensive and systematic overview of change causes and effects is missing due to different terminologies and perspectives, lack of distinction between generic and project-specific causes, and lack of validation with industry experts. Therefore, the objective of this study is to identify and classify change causes and effects in construction projects. A multi-case study research method is utilised to achieve the objective of the study. The study provides two contributions to the body of knowledge of change management. First, a comprehensive list of 85 change causes and 45 change effects which are identified from the literature and multi-case study are presented. Around 3951 changes from 19 construction projects are investigated to identify causes and effects. Second, a taxonomy is proposed to classify change causes and effects. The proposed taxonomy consists of three levels with an increasing level of detail of the change cause and effect and it can support project teams to develop strategies to eliminate or minimise changes in the construction project.

description: To improve policy robustness of deep reinforcement learning agents, a line of recent works focus on producing disturbances of the environment. Existing approaches of the literature to generate meaningful disturbances of the environment are adversarial reinforcement learning methods. These methods set the problem as a two-player game between the protagonist agent, which learns to perform a task in an environment, and the adversary agent, which learns to disturb the protagonist via modifications of the considered environment. Both protagonist and adversary are trained with deep reinforcement learning algorithms. Alternatively, we propose in this paper to build on gradient-based adversarial attacks, usually used for classification tasks for instance, that we apply on the critic network of the protagonist to identify efficient disturbances of the environment. Rather than learning an attacker policy, which usually reveals as very complex and unstable, we leverage the knowledge of the critic network of the protagonist, to dynamically complexify the task at each step of the learning process. We show that our method, while being faster and lighter, leads to significantly better improvements in policy robustness than existing methods of the literature.

description: We consider well-posedness of the boundary value problem in presence of an inclusion with complex conductivity $k$. We first consider the transmission problem in $\mathbb{R}^d$ and characterize solvability of the problem in terms of the spectrum of the Neumann-Poincaré operator. We then deal with the boundary value problem and show that the solution is bounded in its $H^1$-norm uniformly in $k$ as long as $k$ is at some distance from a closed interval in the negative real axis. We then show with an estimate that the solution depends on $k$ in its $H^1$-norm Lipschitz continuously. We finally show that the boundary perturbation formula in presence of a diametrically small inclusion is valid uniformly in $k$ away from the closed interval mentioned before. The results for the single inclusion case are extended to the case when there are multiple inclusions with different complex conductivities: We first obtain a complete characterization of solvability when inclusions consist of two disjoint disks and then prove solvability and uniform estimates when imaginary parts of conductivities have the same signs. The results are obtained using the spectral property of the associated Neumann-Poincaré operator and the spectral resolution.

description: Solutions of the quartic Fermat equation in ring class fields of odd conductor over quadratic fields $K=\mathbb{Q}(\sqrt{-d})$ with $-d \equiv 1$ (mod $8$) are shown to be periodic points of a fixed algebraic function $T(z)$ defined on the punctured disk $0< |z|_2 \le \frac{1}{2}$ of the maximal unramified, algebraic extension $\textsf{K}_2$ of the $2$-adic field $\mathbb{Q}_2$. All ring class fields of odd conductor over imaginary quadratic fields in which the prime $p=2$ splits are shown to be generated by complex periodic points of the algebraic function $T$, and conversely, all but two of the periodic points of $T$ generate ring class fields over suitable imaginary quadratic fields. This gives a dynamical proof of a class number relation originally proved by Deuring. It is conjectured that a similar situation holds for an arbitrary prime $p$ in place of $p=2$, where the case $p=3$ has been previously proved by the author, and the case $p=5$ will be handled in Part II.

description: Given a topologically free action of a countable group $G$ on a compact metric space $X$, there is a canonical correspondence between continuous 1-cocycles for this group action and diagonal 1-parameter groups of automorphisms of the reduced crossed product C*-algebra. The KMS spectrum is defined as the set of inverse temperatures for which there exists a KMS state. We prove that the possible KMS spectra depend heavily on the nature of the acting group $G$. For groups of subexponential growth, we prove that the only possible KMS spectra are $\{0\}$, $[0,+\infty)$, $(-\infty,0]$ and $\mathbb{R}$. For certain wreath product groups, which are amenable and of exponential growth, we prove that any closed subset of $\mathbb{R}$ containing zero arises as KMS spectrum. Finally, for certain nonamenable groups including the free group with infinitely many generators, we prove that any closed subset may arise. Besides uncovering a surprising relation between geometric group theoretic properties and KMS spectra, our results provide two simple C*-algebras with the following universality property: any closed subset (containing, resp. not containing zero) arises as the KMS spectrum of a 1-parameter group of automorphisms of this C*-algebra.

description: Zipf's law is a fundamental paradigm in the statistics of written and spoken natural language as well as in other communication systems. We raise the question of the elementary units for which Zipf's law should hold in the most natural way, studying its validity for plain word forms and for the corresponding lemma forms. In order to have as homogeneous sources as possible, we analyze some of the longest literary texts ever written, comprising four different languages, with different levels of morphological complexity. In all cases Zipf's law is fulfilled, in the sense that a power-law distribution of word or lemma frequencies is valid for several orders of magnitude. We investigate the extent to which the word-lemma transformation preserves two parameters of Zipf's law: the exponent and the low-frequency cut-off. We are not able to demonstrate a strict invariance of the tail, as for a few texts both exponents deviate significantly, but we conclude that the exponents are very similar, despite the remarkable transformation that going from words to lemmas represents, considerably affecting all ranges of frequencies. In contrast, the low-frequency cut-offs are less stable.

description: We obtained the magnetic field configurations, including both poloidal and toroidal components, throughout the interior and exterior of magnetars using a realistic equation of state. We divided the magnetized star into the hydromagnetic equilibrium core, Hall equilibrium crust and twisted force-free magnetosphere. We systematically and simultaneously calculated these regions under various boundary conditions using the Green function relaxation method, and noted the following interesting characteristics of these numerical results. First, the strength and structure of core magnetic fields affect the crustal magnetic fields. Second, the current sheet on the core-crust interface affects both internal and external magnetic field configurations. Third, the twisted magnetosphere makes a cross-point of magnetic field lines, such as X-point geometry, in the magnetosphere. The X-point geometry appears and disappears according to the strength of the twisted field in the magnetosphere or the core-crust boundary conditions. Our results mean that both Hall magnetohydrodynamics secular evolution and magnetospheric dynamical evolution are deeply affected by conditions of another region and the core-crust stress of magnetars.

description: We generalize to quantum weighted projective spaces in any dimension previous results of us on K-theory and K-homology of quantum projective spaces `tout court'. For a class of such spaces, we explicitly construct families of Fredholm modules, both bounded and unbounded (that is spectral triples), and prove that they are linearly independent in the K-homology of the corresponding C*-algebra. We also show that the quantum weighted projective spaces are base spaces of quantum principal circle bundles whose total spaces are quantum lens spaces. We construct finitely generated projective modules associated with the principal bundles and pair them with the Fredholm modules, thus proving their non-triviality.

Sheng [arXiv:2009.03492] gave a definition of what is a Rota-Baxter operator on a group. We connect these two notions as follows. It is shown that every Rota-Baxter group gives rise to a skew left brace. Moreover, every skew left brace can be injectively embedded into a Rota-Baxter group. When the additive group of a skew left brace is complete, then this brace is induced by a Rota-Baxter group. We interpret some notions of the theory of skew left braces in terms of Rota-Baxter operators.

description: Direct detector device (DDD) cameras have revolutionized single particle electron cryomicroscopy (cryo-EM). In addition to an improved camera detective quantum efficiency, acquisition of DDD movies allows for correction of movement of the specimen, due both to instabilities in the microscope specimen stage and electron beam-induced movement. Unlike specimen stage drift, beam-induced movement is not always homogeneous within an image. Local correlation in the trajectories of nearby particles suggests that beam-induced motion is due to deformation of the ice layer. Algorithms have already been described that can correct movement for large regions of frames and for > 1 MDa protein particles. Another algorithm allows individual < 1 MDa protein particle trajectories to be estimated, but requires rolling averages to be calculated from frames and fits linear trajectories for particles. Here we describe an algorithm that allows for individual < 1 MDa particle images to be aligned without frame averaging or linear trajectories. The algorithm maximizes the overall correlation of the shifted frames with the sum of the shifted frames. The optimum in this single objective function is found efficiently by making use of analytically calculated derivatives of the function. To smooth estimates of particle trajectories, rapid changes in particle positions between frames are penalized in the objective function and weighted averaging of nearby trajectories ensures local correlation in trajectories. This individual particle motion correction, in combination with weighting of Fourier components to account for increasing radiation damage in later frames, can be used to improve 3-D maps from single particle cryo-EM.

description: The use of sorghum improved variety seeds has been low among sorghum farmers in Tanzania. Due to this, stakeholders such as brewing companies have launched various initiatives to expand the use of improved sorghum seeds. In general, this study was undertaken to assess the contribution of brewing industry to the sorghum value chain in Tanzania. Specifically, this study aims to determine the extent of use of sorghum in brewing (by quantifying the amount of sorghum grain sold to brewing companies and grain off-takers), identifying stakeholders in the value chain, and the impact of the brewing industry on use of improved seeds by smallholder farmers. The study was conducted in 11 districts in 6 regions of Tanzania covering sorghum farmers, grain off-takers, brewing companies, extension officers, and seed producers. Purposive and simple random sampling was used to select respondents: 591 individual farmers, 160 farmers from 16 focus groups, 15grain off-takers, 14 extension officers, 4 Quality Declared Seed (QDS) producers, and 2 brewing companies. Data was then analyzed using descriptive analysis statistics, Probit Regression, and cost-benefit analysis

description: In this article it is studied the 3-brane world in the context of five-dimensional Einstein-Chern-Simons gravity. We started by considering Israel's junction condition for AdS-Chern-Simons gravity. Using the S-expansion procedure, we mapped the AdS-Chern-Simons junction conditions to Einstein-Chern-Simons gravity, allowing us to derive effective four-dimensional Einstein-Chern-Simons field equations.

Metabolic Reprogramming of the Cystic Fibrosis Neutrophil

description: Cystic fibrosis (CF) is the commonest lethal genetic condition affecting Caucasians, arising from a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene on the long arm of chromosome 7. It is a chloride channelopathy, manifesting clinically as a multisystem disorder. The major cause of morbidity and mortality in CF is neutrophilic lung disease, though significant debate exists as to whether the main determinant of this is an intrinsic defect due to defective CFTR within the CF cell, or rather the frequent cycles of infection and sustained inflammation that characterize the condition. Here we show a potential role for metabolic reprogramming in CF airways inflammation, demonstrating the existence of upregulated aerobic glycolysis, known as a Warburg effect, in the CF neutrophil, with implications for intracellular pH regulation and release of the master pro-inflammatory cytokine interleukin (IL)-1β. This shift to a state of increased aerobic glycolysis relies on an intact PKM2/succinate/HIF-1α axis and results in decreased cytosolic pH and increased production of lactate and the IL-1β precursor pro-IL-1β, it’s processing in the lung driven by the NLRP3 inflammasome via caspase-1. We demonstrate that IL-1β levels are significantly increased in the CF lung, and identify IL-1β as an airway biomarker of CF lung disease severity by correlating it with accepted measures of clinical outcome such as FEV1 and the CF-ABLE score, a validated CF-specific clinical prognostic tool developed by this group. We show that this phenomenon is driven by inflammation, rather than an intrinsic CFTR defect, and is abrogated both by inhibition of Warburg metabolism and specific inhibition of NLRP3 by small molecules in vivo, identifying the 4 inflammasome as a therapeutic target in CF. This study also describes the development of Temperature-controlled Two-step Rapid Isolation of Sputum (TETRIS), a specialized method of sputum processing designed to facilitate multicentre studies assessing the effect of therapies targeting IL-1β and other key inflammatory mediators, such as neutrophil elastase (NE), in CF.

description: The original and amplitude permutations are two basic ordinal patterns; however, their relationship has received little attention. This paper compares the original and amplitude permutations used to characterize vector structures. To accurately convey the vector structure, we modify indexes of equal values in the permutations to be the same ones in each group of equalities. Comparative analysis suggests that the amplitude permutation, comprising the positions of the original values in the reordered vector, directly reflects the vector's temporal structure, whereas the original permutation, consisting of the indexes of reorganized values in the original vector, conveys the structural pattern of the reorganized vector. Moreover, we clarify the association of the original and amplitude permutations with timeand amplitude-symmetric vectors, thus contributing to the fields of symbolic analysis, topological data analysis, and so on.

description: Ergodicity in quantum many-body systems is - despite its fundamental importance - still an open problem. Many-body localization provides a general framework for quantum ergodicity, and may therefore offer important insights. However, the characterization of many-body localization through simple observables is a difficult task. In this article, we introduce a measure for distances in Hilbert space for spin-1/2 systems that can be interpreted as a generalization of the Anderson localization length to the many-body Hilbert space. We show that this many-body localization length is equivalent to a simple local observable in real space, which can be measured in experiments of superconducting qubits, polar molecules, Rydberg atoms, and trapped ions. Using the many-body localization length and a necessary criterion for ergodicity that it provides, we study many-body localization and quantum ergodicity in power-law-interacting Ising models subject to disorder in the transverse field. Based on the nonequilibrium dynamical renormalization group, numerically exact diagonalization, and an analysis of the statistics of resonances we find a many-body localized phase at infinite temperature for small power-law exponents. Within the applicability of these methods, we find no indications of a delocalization transition.

description: We study almost complex structures with lower bounds on the rank of the Nijenhuis tensor. Namely, we show that they satisfy an $h$-principle. As a consequence, all parallelizable manifolds and all manifolds of dimension $2n\geq 10$ (respectively $\geq 6$) admit a almost complex structure whose Nijenhuis tensor has maximal rank everywhere (resp. is nowhere trivial). For closed $4$-manifolds, the existence of such structures is characterized in terms of topological invariants. Moreover, we show that the Dolbeault cohomology of non-integrable almost complex structures is often infinite dimensional (even on compact manifolds).

description: A Schwarz function on an open domain $Ω$ is a holomorphic function satisfying $S(ζ)=\overlineζ$ on $Γ$, which is part of the boundary of $Ω$. Sakai in 1991 gave a complete characterization of the boundary of a domain admitting a Schwarz function. In fact, if $Ω$ is simply connected and $Γ=\partial Ω\cap D(ζ,r)$, then $Γ$ has to be regular real analytic. This paper is an attempt to describe $Γ$ when the boundary condition is slightly relaxed. In particular, three different scenarios over a simply connected domain $Ω$ are treated: when $f_1(ζ)=\overlineζf_2(ζ)$ on $Γ$ with $f_1,f_2$ holomorphic and continuous up to the boundary, when $\mathcal{U}/\mathcal{V}$ equals certain real analytic function on $Γ$ with $\mathcal{U},\mathcal{V}$ positive and harmonic on $Ω$ and vanishing on $Γ$, and when $S(ζ)=Φ(ζ,\overlineζ)$ on $Γ$ with $Φ$ a holomorphic function of two variables. It turns out that the boundary piece $Γ$ can be, respectively, anything from $C^\infty$ to merely $C^1$, regular except finitely many points, or regular except for a measure zero set.
