description: Pollution associated with polycyclic aromatic hydrocarbons (PAHs) and carbon emissions, resulting from fossil fuel combustion, is a matter of major concern in India. In this work, the distribution, variations, sources and fate of twelve PAHs (phenanthrene, anthracene, fluoranthene, pyrene, benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenz[a,h]anthracene, benzo[ghi]perylene and indeno[1,2,3-cd]pyrene) and carbonaceous particulate matter (elemental/black carbon (EC/BC), organic carbon (OC) and inorganic/carbonate carbon (CC)) in the air, road dust and sediments of three cities in the most industrialized area of Central India (Chhattisgarh state) are reported. The PM and road dust/sediment samples were collected by using a low volume air sampler and a stainless–steel scoop, respectively. PAHs were extracted into organic solvents and the dried residue was dissolved into acetonitrile for analysis. Carbons and PAHs were analyzed by thermal and chromatographic methods. Concentrations of particulate matter (PM10), total carbon (TC = EC + OC + CC) and total polycyclic aromatic hydrocarbons (∑12PAHs) of 116–523 µg m−3, 22.1–179.6 µg m−3 and 37.7–164.9 ng m−3, respectively, were found in air at the beginning of the study (2007/08). Concentrations of 6.02 − 9.87% (TC) and 8689 − 87458 ng g−1 (Σ12PAHs) were detected in road dust, while relatively lower concentrations were observed in sediments, in the 4.99–10.78% and 4721–11768 ng g−1 range, respectively. Regarding monthly and seasonal variations, the highest PAHs and TC concentrations occurred in December/January and in the winter season. Spatial (residential, commercial, and industrial areas) and temporal (2008-2015) variations of these pollutants are also discussed, together with their source apportionment based on factor analysis. Given that benzo[a]pyrene and ∑12PAHs concentrations clearly exceed the permissible limits, and that the concentration of PAHs in dust for one of the three cities under study (Bhilai) is the highest reported in the literature, this study shows the urgent need for continuous monitoring of organic aerosol constituents in the ambient air of the cities in this region.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We give a description of double parton scattering with measured transverse momenta in the final state, extending the formalism for factorisation and resummation developed by Collins, Soper and Sterman for the production of colourless particles. After a detailed analysis of their colour structure, we derive and solve evolution equations in rapidity and renormalisation scale for the relevant soft factors and double parton distributions. We show how in the perturbative regime, transverse momentum dependent double parton distributions can be expressed in terms of simpler nonperturbative quantities and compute several of the corresponding perturbative kernels at one-loop accuracy. We then show how the coherent sum of single and double parton scattering can be simplified for perturbatively large transverse momenta, and we discuss to which order resummation can be performed with presently available results. As an auxiliary result, we derive a simple form for the square root factor in the Collins construction of transverse momentum dependent parton distributions.

description: We investigate different measures of stability of quantum statistical ensembles with respect to local measurements. We call a quantum statistical ensemble "stable" if a small number of local measurements cannot significantly modify the total-energy distribution representing the ensemble. First, we numerically calculate the evolution of the stability measure introduced in our previous work [Phys. Rev. E 94, 062106 (2016)] for an ensemble representing a mixture of two canonical ensembles with very different temperatures in a periodic chain of interacting spins-1/2. Second, we propose other possible stability measures and discuss their advantages and disadvantages. We also show that, for small system sizes available to numerical simulations of local measurements, finite-size effects are rather pronounced.

description: Herein we report the synthesis, DFT calculations, and molecular docking studies of a pyrazole derivative, (E)-N'-benzylidene-5-methyl-1H-pyrazole-3-carbohydrazide (E-BMPC) as α-glucosidase and α-amylase inhibitor. Molecular structure of E-BMPC has been confirmed by single crystal X-ray diffraction (XRD), FTIR, 1H, and 13C NMR spectra. In addition, density functional theory (DFT) calculations on E-BMPC were carried out to obtain frontier molecular orbital energies and first-order static hyperpolarizability (β). The α-amylase and α-glucosidase enzyme inhibitory of E-BMPC was also tested. E-BMPC displayed moderate inhibitory activity with IC50 values 310.57 ± 2.67 and 182.19 ± 3.20 against α-glucosidase and α-amylase enzymes, respectively. Molecular docking analysis provided the inhibition constant of E-BMPC molecule for α-amylase enzyme as 33.60 µM. Both in vitro and in silico enzyme inhibition studies showed that E-BMPC molecule is a better inhibitor for α-amylase than α-glucosidase. The β parameter for the molecule under investigation was also calculated as 4.2 × 10−30 esu.

description: We prove an enumerative formula for the algebraic Euler characteristic of Brill-Noether varieties, parametrizing degree d and rank r linear series on a general genus g curve, with ramification profiles specified at up to two general points. Up to sign, this Euler characteristic is the number of standard set-valued tableaux of a certain skew shape with g labels. We use a flat degeneration via the Eisenbud-Harris theory of limit linear series, relying on moduli-theoretic advances of Osserman and Murray-Osserman; the count of set-valued tableaux is an explicit enumeration of strata of this degeneration.

description: This paper examines the intersections between youth access to land, migration decisions and employment opportunities using nationally representative and multi-year data from multiple African countries. We document evidence on the evolving dynamics in land distribution and ownership patterns, the effect of land access on youth livelihood choices and development of rental and sales market in the region. The report highlights six key findings: First, a progressively smaller proportion of young people are inheriting land due to land scarcity. Second, rural youth who do inherit land will need to wait longer to gain access to it because of significantly longer adult life spans. Third, land scarcity has been driving rapid changes in the land ownership and distribution patterns over the past decade and shaping the employment and migration decisions of rural youth. Fourth, the share of individual labour time devoted to farming is declining over time across age categories and gender, signifying that continued economic transformation processes are underway in Africa.

description: Causal mediation analysis can improve understanding of the mechanisms underlying epidemiologic associations. However, the utility of natural direct and indirect effect estimation has been limited by the assumption of no confounder of the mediator-outcome relationship that is affected by prior exposure---an assumption frequently violated in practice. We build on recent work that identified alternative estimands that do not require this assumption and propose a flexible and double robust semiparametric targeted minimum loss-based estimator for data-dependent stochastic direct and indirect effects. The proposed method treats the intermediate confounder affected by prior exposure as a time-varying confounder and intervenes stochastically on the mediator using a distribution which conditions on baseline covariates and marginalizes over the intermediate confounder. In addition, we assume the stochastic intervention is given, conditional on observed data, which results in a simpler estimator and weaker identification assumptions. We demonstrate the estimator's finite sample and robustness properties in a simple simulation study. We apply the method to an example from the Moving to Opportunity experiment. In this application, randomization to receive a housing voucher is the treatment/instrument that influenced moving to a low-poverty neighborhood, which is the intermediate confounder. We estimate the data-dependent stochastic direct effect of randomization to the voucher group on adolescent marijuana use not mediated by change in school district and the stochastic indirect effect mediated by change in school district. We find no evidence of mediation. Our estimator is easy to implement in standard statistical software, and we provide annotated R code to further lower implementation barriers.

Publisher: name: Elsevier
Year: 2022

description: Present nuclear detection techniques prevents us from determining if the analogue of a Rydberg molecule exists for the nuclear case. But nothing in nature disallows their existence. As in the atomic case, Rydberg nuclear molecules would be a laboratory for new aspects and applications of nuclear physics. We propose that Rydberg nuclear molecules, which represent the exotic, halo nuclei version, such as ¹¹Be + ¹¹Be, of the well known quasimolecules observed in stable nuclei such as ¹²C + ¹²C, might be common structures that could manifest their existence along the dripline. A study of possible candidates and the expected structure of such exotic clustering of two halo nuclei: the Rydberg nuclear molecules, is made on the basis of three different methods. It is shown that such cluster structures might be stable and unexpectedly common.
Relative distance between tracers as a measure of diffusivity within moving aggregates

description: Tracking of particles, be it a passive tracer or an actively moving bacterium in the growing bacterial colony, is a powerful technique to probe the physical properties of the environment of the particles. One of the most common measures of particle motion driven by fluctuations and random forces is its diffusivity, which is routinely obtained by measuring the mean squared displacement of the particles. However, often the tracer particles may be moving in a domain or an aggregate which itself experiences some regular or random motion and thus masks the diffusivity of tracers. Here we provide a method for assessing the diffusivity of tracer particles within mobile aggregates by measuring the so-called mean squared relative distance (MSRD) between two tracers. We provide analytical expressions for both the ensemble and time averaged MSRD allowing for direct identification of diffusivities from experimental data.

description: A mild and efficient protocol was developed for the synthesis of pyrazole and 2°-amine hybrid conjugates through an InCl3 Ugi four-component reaction followed by a base mediated secondary amine coupling reaction. MCRs have been used extensively in the field of combinatorial chemistry, which offers the synthesis of libraries of similar molecules in a parallel fashion. A small library of novel N-allyl-N-(1-(4-(aminomethyl) phenyl)-2-(tert-butylamino)-2-oxoethyl)-1,3-diphenyl-1H-pyrazole-4-carboxamide scaffold was designed and synthesized through a one-pot four-component Ugi reaction, the resulting Ugi product pyrazole derivative coupled with various secondary amines to prepare target pyrazole – amine conjugate molecules. The structures of synthesized conjugates confirmed by spectroscopic techniques (NMR, C, H, N analysis, and MS). The in vitro antimicrobial survey of these pyrazole-secondary amine conjugates was supported by DFT studies; thereby notifies the conjugates are promising antimicrobial agents and are comparable to the standard antimicrobial molecules such as ampicilin, griseofulvin, isoniazide and rifampicin.

Generalised Scherk-Schwarz reductions from gauged supergravity

description: A procedure is described to construct generalised Scherk-Schwarz uplifts of gauged supergravities. The internal manifold, fluxes, and consistent truncation Ansatz are all derived from the embedding tensor of the lower-dimensional theory. We first describe the procedure to construct generalised Leibniz parallelisable spaces where the vector components of the frame are embedded in the adjoint representation of the gauge group, as specified by the embedding tensor. This allows us to recover the generalised Scherk-Schwarz reductions known in the literature and to prove a no-go result for the uplift of $ω$-deformed SO(p,q) gauged maximal supergravities. We then extend the construction to arbitrary generalised Leibniz parallelisable spaces, which turn out to be torus fibrations over manifolds in the class above.

description: Qualquer abordagem sobre a fábula implica que se considere a multiplicidade de significados do conceito. Num dos seus sentidos (o que mais nos importa no presente artigo), concorre com a noção de «apólogo» – com a qual chega a confundir-se -, definindo-se ambos por uma vertente marcadamente moralizadora e por uma dimensão narrativa em que o elemento fantasioso está presente. A obra de D. Francisco Manuel de Melo actualiza algumas das acepções do termo, seja como resultado da efabulação do autor, nos Apólogos dialogais, seja na recriação da tradição esópica.

description: Oxadiazole-based-thiourea analogs (1–18) were synthesized and evaluated for their β-glucuronidase inhibitory activity. All analogs showed extensive β-glucuronidase inhibitory potential ranging between (IC50 = 2.20 ± 0.01 µM) to (IC50 = 52.25 ± 1.20 µM) by comparing with the standard D-Saccharic acid 1,4-lactone (IC50 = 48.30 ± 1.25 µM). Among the series, analogue 7 having IC50 value (IC50 = 2.20 ± 0.01 µM)), 16 (IC50 = 4.40 ± 0.10 µM) and 4 (IC50 = 9.20 ± 0.20 µM) showed an excellent inhibitory potential greater than that of standard D-saccharic acid-1,4- lactone. Analogue 7 (IC50 = 2.20 ± 0.01 µM) of this series having flouro group at ortho-position of phenyl ring was recognized to be most active analogue due to involvement of flouro group in hydrogen bonding with the enzyme active site. In addition, all synthesized derivatives characterized by using High Resolution Mass Spectrometry (HR-MS), 13C-NMR and Nuclear Magnetic Resonance Spectroscopy (1H-NMR proton). For better understanding of binding mode of interactions of these active analogs molecular docking study was performed. Structure Activity relationship (SAR) was also discussed.

description: Os textos metalinguísticos do século XVIII testemunham o uso das palavras fábula e fabuloso na língua portuguesa, em contextos que não se limitam à reflexão sobre os géneros literários. Nos textos que descrevem costumes, mitos, práticas religiosas e casos prodigiosos, a classificação do discurso como fabuloso pode transmitir julgamentos de valor motivados pela reacção à heterodoxia.

description: We study a tight-binding model of interacting Majorana (Hermitian) modes on a square lattice. The model may have an experimental realization in a superconducting-film--topological-insulator heterostructure in a magnetic field. We find a rich phase diagram, as a function of interaction strength, including a superfluid phase with spontaneous breaking of an emergent $U(1)$ symmetry, separated by a supersymmetric transition from a gapless normal phase.

description: We consider the classification problem for several classes of countable structures which are "vertex-transitive", meaning that the automorphism group acts transitively on the elements. (This is sometimes called homogeneous.) We show that the classification of countable vertex-transitive digraphs and partial orders are Borel complete. We identify the complexity of the classification of countable vertex-transitive linear orders. Finally we show that the classification of vertex-transitive countable tournaments is properly above $E_0$ in complexity.

description: This arXiv repository is a bundle of two closely related papers. Abstract of the first paper: In systems governed by "chaotic" local Hamiltonians, we conjecture the universality of eigenstate entanglement (defined as the average entanglement entropy of all eigenstates) by proposing an exact formula for its dependence on the subsystem size. This formula is derived from an analytical argument based on a plausible assumption, and is supported by numerical simulations. Abstract of the second paper: In systems governed by chaotic local Hamiltonians, the first paper conjectured the universality of the average entanglement entropy of all eigenstates by proposing an exact formula for its dependence on the subsystem size. In this note, I extend this result to the average entanglement entropy of a constant fraction of eigenstates in the middle of the energy spectrum. The generalized formula is supported by numerical simulations of various chaotic spin chains.
Hunting dark matter with MeerKAT
Creators: name: Lavis, Natasha
Publisher: name: Zenodo
Year: 2024

description: The nature of dark matter remains a gap within our current cosmological paradigm, but MeerKAT may hold the key to helping us reveal this occult substance. Historically radio-frequency indirect dark matter detection has been avoided due to the complication of characterizing magnetic field environments. With the advanced capabilities of the new generation of interferometers, radio detection may prove to be a robust way to examine the alleged signals of dark matter annihilation. The potential of MeerKAT, currently the world's best interferometer, as a dark matter search engine has been only minimally investigated. Galaxy clusters prove to be robust labs for radio dark matter detection, as they are known to host large-scale diffuse emission, are dark matter dominated, and contain large-scale magnetic fields. MeerKAT Galaxy Cluster Legacy Survey (MGCLS) provides an abundance of target environments. We use the wealth of data available to investigate dark matter emission in a sample of clusters. Through an integrated flux comparison of predicted signals to those observed, we have produced competitive upper limits on the annihilation cross-section, where under the assumption of a thermal relic population weakly interacting massive particles (WIMPs) have been excluded for masses less than 800 GeV in the galaxy cluster Abell 4038. It is expected that targets in which no halo-like diffuse emission is observed may further improve on these results, by limiting the maximum allowed signal from dark matter to the faintest emission observable by MeerKAT. I will present the results of our investigation on a set of massive clusters where no diffuse emission has been detected.

description: We present the K2 light curves of a large sample of untargeted Main Belt asteroids (MBAs) detected with the Kepler space telescope. The asteroids were observed within the Uranus superstamp, a relatively large, continuous field with low stellar background designed to cover the planet Uranus and its moons during Campaign 8 of the K2 mission. The superstamp offered the possibility to obtain precise, uninterrupted light curves of a large number of MBAs and thus to determine unambiguous rotation rates for them. We obtained photometry for 608 MBAs, and were able to determine or estimate rotation rates for 90 targets, of which 86 had no known values before. In an additional 16 targets we detected incomplete cycles and/or eclipse-like events. We found the median rotation rate to be significantly longer than that of the ground-based observations indicating that the latter are biased towards shorter rotation rates. Our study highlights the need and benefits of further continuous photometry of asteroids.

Interaction effects with varying $N$ in SU($N$) symmetric fermion lattice systems

description: The interaction effects in ultracold Fermi gases with SU($N$) symmetry are studied non-perturbatively in half-filled one-dimensional lattices by employing quantum Monte Carlo simulations.We find that as $N$ increases, weak and strong interacting systems are driven to a crossover region, but from opposite directions as a convergence of itinerancy and Mottness.In the weak interaction region, particles are nearly itinerant,and inter-particle collisions are enhanced by $N$, resulting in the amplification of interaction effects. In contrast, in the strong coupling region, increasing $N$ softens the Mott-insulating background through the enhanced virtual hopping processes.The crossover region exhibits nearly $N$-independent physical quantities, including the relative bandwidth, Fermi distribution, and the spin structure factor.The difference between even-$N$ and odd-$N$ systems is most prominent at small $N$'s with strong interactions, since the odd case allows local real hopping with an energy scale much larger than the virtual one.The above effects can be experimentally tested in ultracold atom experiments with alkaline-earth (-like) fermions such as $^{87}$Sr ($^{173}$Yb).

description: Contact processes form a large and highly interesting class of dynamic processes on networks, including epidemic and information spreading. While devising stochastic models of such processes is relatively easy, analyzing them is very challenging from a computational point of view, particularly for large networks appearing in real applications. One strategy to reduce the complexity of their analysis is to rely on approximations, often in terms of a set of differential equations capturing the evolution of a random node, distinguishing nodes with different topological contexts (i.e., different degrees of different neighborhoods), like degree-based mean field (DBMF), approximate master equation (AME), or pair approximation (PA). The number of differential equations so obtained is typically proportional to the maximum degree kmax of the network, which is much smaller than the size of the master equation of the underlying stochastic model, yet numerically solving these equations can still be problematic for large kmax. In this paper, we extend AME and PA, which has been proposed only for the binary state case, to a multi-state setting and provide an aggregation procedure that clusters together nodes having similar degrees, treating those in the same cluster as indistinguishable, thus reducing the number of equations while preserving an accurate description of global observables of interest. We also provide an automatic way to build such equations and to identify a small number of degree clusters that give accurate results. The method is tested on several case studies, where it shows a high level of compression and a reduction of computational time of several orders of magnitude for large networks, with minimal loss in accuracy.

description: Interactive-proof games model the scenario where an honest party interacts with powerful but strategic provers, to elicit from them the correct answer to a computational question. Interactive proofs are increasingly used as a framework to design protocols for computation outsourcing. Existing interactive-proof games largely fall into two categories: either as games of cooperation such as multi-prover interactive proofs and cooperative rational proofs, where the provers work together as a team; or as games of conflict such as refereed games, where the provers directly compete with each other in a zero-sum game. Neither of these extremes truly capture the strategic nature of service providers in outsourcing applications. How to design and analyze non-cooperative interactive proofs is an important open problem. In this paper, we introduce a mechanism-design approach to define a multi-prover interactive-proof model in which the provers are rational and non-cooperative---they act to maximize their expected utility given others' strategies. We define a strong notion of backwards induction as our solution concept to analyze the resulting extensive-form game with imperfect information. Our protocols provide utility gap guarantees, which are analogous to soundness gap in classic interactive proofs. At a high level, a utility gap of u means that the protocol is robust against provers that may not care about a utility loss of 1/u. We fully characterize the complexity of our proof system under different utility gap guarantees. For example, we show that with a polynomial utility gap, the power of non-cooperative rational interactive proofs is exactly P^NEXP.
