description: Using an organometallic precursor, TiO$_2$ coatings were fabricated on surfaces of quartz, zircon and rutile sands. X ray Diffraction, X ray Fluorescence, UV Vis spectroscopy and surface area measurement were used to characterise support materials. The phase composition and morphology of the coatings were characterised by laser Raman spectroscopy and SEM respectively. A packed bed reactor was used to study the inactivation of Escherichia coli in recirculating water by the supported photocatalysts. It was found that the sand grains were well coated with a homogenous layer of TiO2 and coatings were well adhered, exhibiting a mixed anatase rutile composition after firing at 850C. Photocatalytic activity was highest in coatings applied to quartz sand, although sterilisation of the recirculating water was not achieved with any of the materials investigated. The advantages of quartz as a TiO$_2$ photocatalyst support material are likely a result of this materials higher purity and optical transmittance. Potential enhancement through Si doping cannot be ruled out.

description: Despite its decades' long therapeutic use in psychiatry, the biological mechanisms underlying lithium's mood-stabilizing effects have remained largely elusive. Here, we investigated the effect of lithium on tryptophan breakdown via the kynurenine pathway using immortalized human microglia cells, primary human microglia isolated from surgical specimens, and microglia-like cells differentiated from human induced pluripotent stem cells. Interferon (IFN)-gamma, but not lipopolysaccharide, was able to activate immortalized human microglia, inducing a robust increase in indoleamine-2,3-dioxygenase (IDO1) mRNA transcription, IDO1 protein expression, and activity. Further, chromatin immunoprecipitation verified enriched binding of both STAT1 and STAT3 to the IDO1 promoter. Lithium counteracted these effects, increasing inhibitory GSK3 beta(S9) phosphorylation and reducing STAT1(S727) and STAT3(Y705) phosphorylation levels in IFN-gamma treated cells. Studies in primary human microglia and hiPSC-derived microglia confirmed the anti-inflammatory effects of lithium, highlighting that IDO activity is reduced by GSK3 inhibitor SB-216763 and STAT inhibitor nifuroxazide via downregulation of P-STAT1(S727) and P-STAT3(Y705). Primary human microglia differed from immortalized human microglia and hiPSC derived microglia-like cells in their strong sensitivity to LPS, resulting in robust upregulation of IDO1 and anti-inflammatory cytokine IL-10. While lithium again decreased IDO1 activity in primary cells, it further increased release of IL-10 in response to LPS. Taken together, our study demonstrates that lithium inhibits the inflammatory kynurenine pathway in the microglia compartment of the human brain.

description: The slope of a supracellular molecular gradient has long been thought to orient and coordinate planar cell polarity (PCP). Here we demonstrate and measure that gradient. Dachsous (Ds) is a conserved and elemental molecule of PCP; Ds forms intercellular bridges with another cadherin molecule, Fat (Ft), an interaction modulated by the Golgi protein Four-jointed (Fj). Using genetic mosaics and tagged Ds, we measure Ds in vivo in membranes of individual cells over a whole metamere of the Drosophila abdomen. We find as follows. (i) A supracellular gradient rises from head to tail in the anterior compartment (A) and then falls in the posterior compartment (P). (ii) There is more Ds in the front than the rear membranes of all cells in the A compartment, except that compartment's most anterior and most posterior cells. There is more Ds in the rear than in the front membranes of all cells of the P compartment. (iii) The loss of Fj removes intracellular asymmetry anteriorly in the segment and reduces it elsewhere. Additional experiments show that Fj makes PCP more robust. Using Dachs (D) as a molecular indicator of polarity, we confirm that opposing gradients of PCP meet slightly out of register with compartment boundaries.

description: A Poisson manifold $(M^{2n},\p)$ is $b$-symplectic if $\bigwedge^n\p$ is transverse to the zero section. In this paper we apply techniques native to Symplectic Topology to address questions pertaining to $b$-symplectic manifolds. We provide constructions of $b$-symplectic structures on open manifolds by Gromov's $h$-principle, and of $b$-symplectic manifolds with a prescribed singular locus, by means of surgeries.

description: Consider an Itô process $X$ satisfying the stochastic differential equation $dX=a(X)\,dt+b(X)\,dW$ where $a,b$ are smooth and $W$ is a multidimensional Brownian motion. Suppose that $W_n$ has smooth sample paths and that $W_n$ converges weakly to $W$. A central question in stochastic analysis is to understand the limiting behavior of solutions $X_n$ to the ordinary differential equation $dX_n=a(X_n)\,dt+b(X_n)\,dW_n$. The classical Wong--Zakai theorem gives sufficient conditions under which $X_n$ converges weakly to $X$ provided that the stochastic integral $\int b(X)\,dW$ is given the Stratonovich interpretation. The sufficient conditions are automatic in one dimension, but in higher dimensions the correct interpretation of $\int b(X)\,dW$ depends sensitively on how the smooth approximation $W_n$ is chosen. In applications, a natural class of smooth approximations arise by setting $W_n(t)=n^{-1/2}\int_0^{nt}v\circϕ_s\,ds$ where $ϕ_t$ is a flow (generated, e.g., by an ordinary differential equation) and $v$ is a mean zero observable. Under mild conditions on $ϕ_t$, we give a definitive answer to the interpretation question for the stochastic integral $\int b(X)\,dW$. Our theory applies to Anosov or Axiom A flows $ϕ_t$, as well as to a large class of nonuniformly hyperbolic flows (including the one defined by the well-known Lorenz equations) and our main results do not require any mixing assumptions on $ϕ_t$. The methods used in this paper are a combination of rough path theory and smooth ergodic theory.

description: Distributed consensus in the Wasserstein metric space of probability measures on the real line is introduced in this work. Convergence of each agent's measure to a common measure is proven under a weak network connectivity condition. The common measure reached at each agent is one minimizing a weighted sum of its Wasserstein distance to all initial agent measures. This measure is known as the Wasserstein barycenter. Special cases involving Gaussian measures, empirical measures, and time-invariant network topologies are considered, where convergence rates and average-consensus results are given. This work has possible applicability in computer vision, machine learning, clustering, and estimation.

description: Consider a strongly $b$-multiplicative sequence and a prime $p$. Studying its $p$-rarefaction consists in characterizing the asymptotic behaviour of the sums of the first terms indexed by the multiples of $p$. The integer values of the "norm" $3$-variate polynomial $\mathcal N_{p,i_1,i_2}(Y_0,Y_1,Y_2)\!:=\!\prod_{j=1}^{p-1}\left(Y_0{+}ζ_p^{i_1j}Y_1{+}ζ_p^{i_2j}Y_2\right),$ where $ζ_p$ is a primitive $p$-th root of unity, and $i_1,i_2{\in}\{1,2,\dots,p{-}1\},$ determine this asymptotic behaviour. It will be shown that a combinatorial method can be applied to $\mathcal N_{p,i_1,i_2}(Y_0,Y_1,Y_2).$ The method enables deducing functional relations between the coefficients as well as various properties of the coefficients of $\mathcal N_{p,i_1,i_2}(Y_0,Y_1,Y_2)$, in particular for $i_1{=}1,i_2{=}2,3.$ This method provides relations between binomial coefficients. It gives new proofs of the two identities $\prod_{j=1}^{p-1}\left(1{-}ζ_p^j\right){=}p$ and $\prod_{j=1}^{p-1}\left(1{+}ζ_p^j{-}ζ_p^{2j}\right){=}L_p$ (the $p$-th Lucas number). The sign and the residue modulo $p$ of the symmetric polynomials of $1{+}ζ_p{-}ζ_p^2$ can also be obtained. An algorithm for computation of coefficients of $\mathcal N_{p,i_1,i_2}(Y_0,Y_1,Y_2)$ is developed.

A Non-Perturbative Renormalization Group approach to quantum XY spin models

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We present a Lattice Non-Perturbative Renormalization Group (NPRG) approach to quantum XY spin models by using a mapping onto hardcore bosons. The NPRG takes as initial condition of the renormalization group flow the (local) limit of decoupled sites, allowing us to take into account the hardcore constraint exactly. The initial condition of the flow is equivalent to the large $S$ classical results of the corresponding spin system. Furthermore, the hardcore constraint is conserved along the RG flow, and we can describe both local and long-distance fluctuations in a non-trivial way. We discuss a simple approximation scheme, and solve the corresponding flow equations. We compute both the zero-temperature thermodynamics and the finite temperature phase diagram on the square and cubic lattices. The NPRG allows us to recover the correct critical physics at finite temperature in two and three dimensions. The results compare well with numerical simulations.

description: We derive a sharp bound as the quantum speed limit (QSL) for the minimal evolution time of quantum open systems in the non-Markovian strong-coupling regime with initial mixed states by considering the effects of both renormalized Hamiltonian and dissipator. For a non-Markovian quantum open system, the possible evolution time between two arbitrary states is not unique, among the set of which we find that the minimal one and its QSL can decrease more steeply by adjusting the coupling strength of the dissipator, which thus provides potential improvements of efficiency in many quantum physics and quantum information areas.

description: Studying mechanisms of bacterial biofilm generation is of vital importance to understanding bacterial cell–cell communication, multicellular cohabitation principles, and the higher resilience of microorganisms in a biofilm against antibiotics. Biofilms of the nonpathogenic, gram-positive soil bacterium Bacillus subtilis serve as a model system with biotechnological potential toward plant protection. Its major extracellular matrix protein components are TasA and TapA. The nature of TasA filaments has been of debate, and several forms, amyloidic and non-Thioflavin T-stainable have been observed. Here, we present the three-dimensional structure of TapA and uncover the mechanism of TapA-supported growth of nonamyloidic TasA filaments. By analytical ultracentrifugation and NMR, we demonstrate TapA-dependent acceleration of filament formation from solutions of folded TasA. Solid-state NMR revealed intercalation of the N-terminal TasA peptide segment into subsequent protomers to form a filament composed of β-sandwich subunits. The secondary structure around the intercalated N-terminal strand β0 is conserved between filamentous TasA and the Fim and Pap proteins, which form bacterial type I pili, demonstrating such construction principles in a gram-positive organism. Analogous to the chaperones of the chaperone-usher pathway, the role of TapA is in donating its N terminus to serve for TasA folding into an Ig domain-similar filament structure by donor-strand complementation. According to NMR and since the V-set Ig fold of TapA is already complete, its participation within a filament beyond initiation is unlikely. Intriguingly, the most conserved residues in TasA-like proteins (camelysines) of Bacillaceae are located within the protomer interface.

description: Metastasis is the process by which cells from a primary tumor disperse and form new tumors at distant anatomical locations. The treatment and prevention of metastatic cancer remains an extremely challenging problem. This work introduces a novel biologically motivated objective function to the radiation optimization community that takes into account metastatic risk instead of the status of the primary tumor. In this work, we consider the problem of developing fractionated irradiation schedules that minimize production of metastatic cancer cells while keeping normal tissue damage below an acceptable level. A dynamic programming framework is utilized to determine the optimal fractionation scheme. We evaluated our approach on a breast cancer case using the heart and the lung as organs-at-risk (OAR). For small tumor $α/β$ values, hypo-fractionated schedules were optimal, which is consistent with standard models. However, for relatively larger $α/β$ values, we found the type of schedule depended on various parameters such as the time when metastatic risk was evaluated, the $α/β$ values of the OARs, and the normal tissue sparing factors. Interestingly, in contrast to standard models, hypo-fractionated and semi-hypo-fractionated schedules (large initial doses with doses tapering off with time) were suggested even with large tumor $α$/$β$ values. Numerical results indicate potential for significant reduction in metastatic risk.

description: Exposure to media could be a relevant factor in radicalization, as people could be exposed to, for instance, extremist content (Conway, 2012), that is, content that can increase hostility towards certain groups (Hansen & Kim, 2011), and recruitment efforts of radical groups (Saleh et al., 2021). Through processes like social learning (Pauwels & Schils, 2016) and the echo chamber effect (Wolfowicz et al., 2021), this media exposure could be associated with radicalization. As youth in particular are exposed to media (Larson et al., 2019; Pandya & Lodha, 2021) and more psychologically vulnerable to radicalization (Oppetit et al., 2019), they are a relevant group to study in this context.

description: Rigidity, arising in discrete geometry, is the property of a structure that does not flex. Laman provides a combinatorial characterization of rigid graphs in the Euclidean plane, and thus rigid graphs in the Euclidean plane have applications in graph theory. We discover a sufficient partition condition of packing spanning rigid subgraphs and spanning trees. As a corollary, we show that a simple graph $G$ contains a packing of $k$ spanning rigid subgraphs and $l$ spanning trees if $G$ is $(4k+2l)$-edge-connected, and $G-Z$ is essentially $(6k+2l - 2k|Z|)$-edge-connected for every $Z\subset V(G)$. Thus every $(4k+2l)$-connected and essentially $(6k+2l)$-connected graph $G$ contains a packing of $k$ spanning rigid subgraphs and $l$ spanning trees. Utilizing this, we show that every $6$-connected and essentially $8$-connected graph $G$ contains a spanning tree $T$ such that $G-E(T)$ is $2$-connected. These improve some previous results. Sparse subgraph covering problems are also studied.

description: Bis zum heutigen Tag ist die allgemeine Relativitätstheorie weithin als die relevante Theorie der Gravitation anerkannt und wurde durch viele Experimente bestätigt. Trotz dieses Erfolges liefert die allgemeine Relativitätstheorie keine Antwort auf viele offene Fragen, die mit Gravitation zusammenhängen. Das endgültige Schicksal scheinbarer Raumzeit-Singularitäten ist eine dieser offenen Fragen. Mögliche Lösungen für Raumzeit-Singularitäten werden in dieser Arbeit diskutiert. In diesen speziellen Lösungen werden Singularitäten durch Raumzeitdefekte ersetzt: Die Singularität des Schwarzen Loches wird durch einen Raumdefekt und die Urknall-Singularität wird durch einen Zeitdefekt ersetzt. In dieser Arbeit untersuchen wir bestimmte Effekte, die Raumzeitdefekte verursachen könnten. Wir berechnen die Geodäten der Raumzeitdefekte. Für den Raumdefekt diskutieren wir seine Linseneigenschaften und die entsprechende Bilderzeugung. Für den Zeitdefekt untersuchen wir die entsprechende nicht singuläre prallende Kosmologie. Wir präsentieren auch einige mögliche beobachtbare Effekte im Zusammenhang mit den Raumzeitdefekten.

We propose two adaptive control schemes to realize the objective of task-space trajectory tracking irrespective of the uncertain kinematics and dynamics. The proposed controllers have the desirable separation property, and we also show that the first adaptive controller with appropriate modifications can yield improved performance, without the expense of conservative gain choice. The performance of the proposed controllers is shown by numerical simulations.

Introducing students to the construction of bilingual scientific argument maps – visual representations of scientific argument structure using two languages – contributes to the quality of bilingual science education as they are a key aspect of bilingual scientific literacy; however, very little is known about how to promote the construction of these maps in bilingual science courses. Here we provide evidence for the claim that peer feedback and instructor feedback can be integrated to support the construction of bilingual scientific argument maps. A pedagogical strategy that integrates both peer feedback and instructor feedback was implemented in a university bilingual science course with 29 students (23 females and 6 males, 18–24 years-old) in Colombia. Results show that the strategy effectively supported the construction of scientific argument maps in Spanish and English. Implications for research and practice are discussed.

description: Nel panorama europeo della critica di danza degli anni Cinquanta, la riflessione attorno all'arte del danzatore occupa una posizione centrale, intrecciandosi con questioni essenziali, come quelle relative alla qualità della fruizione e dell'interpretazione dello spettacolo di danza o alle diverse identità coreutiche (e politiche) nazionali. Dinanzi a un simile stato di cose, l'articolo indaga la riflessione sul danzatore sviluppata dalla rivista romana «Balletto» tra il 1955 e il 1962, da un lato problematizzando i legami con la critica e la storiografia di danza inglese e, dall'altro, mettendo in relazione i discorsi condotti sulla rivista con il panorama produttivo e distributivo della danza in Italia.

description: Analysis of stochastic models of networks is quite important in light of the huge influx of network data in social, information and bio sciences, but a proper statistical analysis of features of different stochastic models of networks is still underway. We propose bootstrap subsampling methods for finding empirical distribution of count features or ``moments'' (Bickel, Chen and Levina [Ann. Statist. 39 (2011) 2280-2301]) and smooth functions of these features for the networks. Using these methods, we cannot only estimate the variance of count features but also get good estimates of such feature counts, which are usually expensive to compute numerically in large networks. In our paper, we prove theoretical properties of the bootstrap estimates of variance of the count features as well as show their efficacy through simulation. We also use the method on some real network data for estimation of variance and expectation of some count features.

description: У статті наголошено на впливі війни, згідного якого активізуються міграційні процеси та втрати людського потенціалу. Зроблено висновки, що міграція українського населення та молоді зокрема пов'язана як із воєнним вторгненням, так і була накопичена на превоєнному етапі поступу України. Запропоновано вибудувати модель державного регулювання міграційних аспірацій молоді в Україні у відповідності до векторів стимулювання виїзду (pull-determinations) та виштовхування (push-determinations) молоді за межі країни. Детермінанти актуалізації міграції молоді України розділено за такими векторами: глобалізаційний, євроінтеграційний, особистісно-професійний, стабілізаційно-гарантійний (вектори стимулювання виїзду); публічно-управлінський, структурний, інституційний, соціально-резильєнтний, гібридний (вектори виштовхування).

description: Let $\mathbf{Q}=(Q_1,\ldots,Q_n)$ be a random vector drawn from the uniform distribution on the set of all $n!$ permutations of $\{1,2,\ldots,n\}$. Let $\mathbf{Z}=(Z_1,\ldots,Z_n)$, where $Z_j$ is the mean zero variance one random variable obtained by centralizing and normalizing $Q_j$, $j=1,\ldots,n$. Assume that $\mathbf {X}_i,i=1,\ldots ,p$ are i.i.d. copies of $\frac{1}{\sqrt{p}}\mathbf{Z}$ and $X=X_{p,n}$ is the $p\times n$ random matrix with $\mathbf{X}_i$ as its $i$th row. Then $S_n=XX^*$ is called the $p\times n$ Spearman's rank correlation matrix which can be regarded as a high dimensional extension of the classical nonparametric statistic Spearman's rank correlation coefficient between two independent random variables. In this paper, we establish a CLT for the linear spectral statistics of this nonparametric random matrix model in the scenario of high dimension, namely, $p=p(n)$ and $p/n\to c\in(0,\infty)$ as $n\to\infty$. We propose a novel evaluation scheme to estimate the core quantity in Anderson and Zeitouni's cumulant method in [Ann. Statist. 36 (2008) 2553-2576] to bypass the so-called joint cumulant summability. In addition, we raise a two-step comparison approach to obtain the explicit formulae for the mean and covariance functions in the CLT. Relying on this CLT, we then construct a distribution-free statistic to test complete independence for components of random vectors. Owing to the nonparametric property, we can use this test on generally distributed random variables including the heavy-tailed ones.

Spectral-Domain-Based Scattering Analysis of Fields Radiated by Distributed Sources in Planar-Stratified Environments with Arbitrarily Anisotropic Layers

description: We discuss the numerically stable, spectral-domain computation and extraction of the scattered electromagnetic field excited by distributed sources embedded in planar-layered environments, where each layer may exhibit arbitrary and independent electrical and magnetic anisotropic response and loss profiles. This stands in contrast to many standard spectral-domain algorithms that are restricted to computing the fields radiated by Hertzian dipole sources in planar-layered environments where the media possess azimuthal-symmetric material tensors (i.e., isotropic, and certain classes of uniaxial, media). Although computing the scattered field, particularly when due to distributed sources, appears (from the analytical perspective, at least) relatively straightforward, different procedures within the computation chain, if not treated carefully, are inherently susceptible to numerical instabilities and (or) accuracy limitations due to the potential manifestation of numerically overflown and (or) numerically unbalanced terms entering the chain. Therefore, primary emphasis herein is given to effecting these tasks in a numerically stable and robust manner for all ranges of physical parameters. After discussing the causes behind, and means to mitigate, these sources of numerical instability, we validate the algorithm's performance against closed-form solutions. Finally, we validate and illustrate the applicability of the proposed algorithm in case studies concerning active remote sensing of marine hydrocarbon reserves embedded deep within lossy, planar-layered media.

description: Suppose that a graph is realized from a stochastic block model where one of the blocks is of interest, but many or all of the vertices' block labels are unobserved. The task is to order the vertices with unobserved block labels into a ``nomination list'' such that, with high probability, vertices from the interesting block are concentrated near the list's beginning. We propose several vertex nomination schemes. Our basic - but principled - setting and development yields a best nomination scheme (which is a Bayes-Optimal analogue), and also a likelihood maximization nomination scheme that is practical to implement when there are a thousand vertices, and which is empirically near-optimal when the number of vertices is small enough to allow comparison to the best nomination scheme. We then illustrate the robustness of the likelihood maximization nomination scheme to the modeling challenges inherent in real data, using examples which include a social network involving human trafficking, the Enron Graph, a worm brain connectome and a political blog network.

description: A novel series of oxo-1,2,3,4-tetrahydropyrazino[1,2-a]indoles were synthesized via a two-step pathway. In the first step, Ugi-four-component condensation of 2-formylindole, amines, (E)-4-alkoxy-4-oxobut-2-enoic acids, and isocyanides gave the corresponding Ugi-adducts. This adduct underwent intramolecular hydroamination in the presence of K2CO3 in CH3CN at room temperature to afford diastereoselective synthesis of a range of oxo-1,2,3,4-tetrahydropyrazino[1,2-a]indoles. A comparison of experimentally observed CD and UV–visible spectra with the theoretical DFT calculated ECD spectra was used to predict the major diastereomer.

description: This material presents the detailed results of a journal paper titled "Size optimization of planar truss systems using modified salp-swarm algorithm" accepted to be published in Engineering Optimization. The abstract of the paper is provided below: This work evaluates the Salp Swarm Algorithms' (SSA) performance for truss system optimization problems and presents a novel method called the Modified Salp Swarm Algorithm (MSSA). The classical SSA and MSSA are compared to the best results in the literature for five truss structures, employing discrete and continuous variables for size optimization (two for each), and one through size and shape optimization. Although the SSA performs poorly and has convergence issues in initial random solutions, it reaches comparable solutions to previously published results, particularly in continuous problems. Contrarily, the MSSA achieves the best solutions for two discrete problems and is relatively close to the best results in the reference literature on continuous problems. Moreover, the MSSA convergence curves exhibit a modest increase in convergence rates, especially for discrete problems. It is envisaged that the findings will contribute to improving solution performance, convergence speed, and security for future real-world applications.

Subjects: spatial soundfield

description: Spatial multizone sound field reproduction aims to regenerate desired sound fields as multiple independent sound fields in isolated zones without unpremeditated interference within a zone from other zones. Such attempts over an extended region of open have proved to be quite arduous and intricate. At high frequencies, significantly large numbers of loudspeakers are required for the reproduction of the sound field over significant areas. This thesis is aimed at using higher order (up to 𝑁th) loudspeakers, with polar responses up to cos (𝑁𝜙) and sin (𝑁𝜙) to resolve the high frequency reproduction issue. The thesis includes the design of the system along with any equations derived to verify the performance of the system for arbitrary sound fields. The equations have been defined with respect to the frequency content of the sound fields and the order and number of sources used. Numerical simulations to verify the equations and corresponding results have also been included.

description: It is considering a problem of selection a new feature space in recognition problems with teacher. For formation the space uses division the set of initial features into previously unknown number of disjoint groups. Extremum of the criterion of grouping is calculated by the stability values of each object in its class on the set of features in the group. Displaying such a set to the numerical axis represents the values of the latent feature in the description of admissible objects. it is proved that the offered method of grouping  forms a monotone sequence of latent features ordered in the relation of informativeness. Transition into the new space of the latent features allows significantly expand opportunities to find a hidden regularities from the databases.
