description: The Strong equivalence Principle (SEP) states that the description of a physical system in a gravitational field is indistinguishable from the description of the same system at rest in an accelerating frame. While this statement holds true in both General Relativity and ordinary Quantum Mechanics, one expects it to fail when quantum gravity corrections are taken into account. In this paper we investigate the possible failure of the SEP in two Quantum Gravity inspired modifications of Quantum Mechanics - Polymer Quantum Mechanics and deformed Heisenberg Algebra. We find that the SEP fails to hold in both these theories. We estimate the deviation from SEP and find in both cases that it is too small to be measured in present day experiments.

description: Structured light has attracted great interest in scientific and technical fields. Here, we demonstrate the first generation of structured air lasing in N2+ driven by 800 nm femtosecond laser pulses. By focusing a vortex pump beam at 800 nm in N2 gas, we generate a vortex superfluorescent radiation of N2+ at 391 nm, which carries the same photon orbital angular momentum as the pump beam. With the injection of a Gaussian seed beam at 391 nm, the coherent radiation is amplified, but the vorticity is unchanged. A new physical mechanism is revealed in the vortex N2+ superfluorescent radiation: the vortex pump beam transfers the spatial spiral phase into the N2+ gain medium, and the Gaussian seed beam picks up the spatial spiral phase and is then amplified into a vortex beam. Moreover, when we employ a pump beam with a cylindrical vector mode, the Gaussian seed beam is correspondingly amplified into a cylindrical vector beam. Surprisingly, the spatial polarization state of the amplified radiation is identical to that of the vector pump beam regardless of whether the Gaussian seed beam is linearly, elliptically, or circularly polarized. Solving three-dimensional coupled wave equations, we show how a Gaussian beam becomes a cylindrical vector beam in a cylindrically symmetric gain medium. This study provides a novel approach to generating structured light via N2+ air lasing.

description: We present an analysis of the effect of a dark photon on the rare kaon decay $K_L \rightarrow π^0 ν{\bar ν}$. All relevant couplings of the dark photon to the Standard Model particles are derived explicitly in terms of the dark photon mass and the mixing parameter. We find that the dark photon yields no more than a few percent correction to the Standard Model branching ratio ${\rm Br}(K_L \rightarrow π^0 ν{\bar ν})$ in the region of interest.

description: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a rapidly growing health care emergency across the world. One of the viral proteases called main protease or Mpro, plays a crucial role in the replication of SARS-CoV-2. As the structure of Mpro of SARS-CoV-2 is similar to the Mpro of SARS-CoV-1 (responsible for SARS outbreak between 2002 and 2004), we hypothesize that the inhibitors of SARS-CoV-1 Mpro can also inhibit the Mpro of SARS-CoV-2. To test this hypothesis, a total of 79 isatin derivatives, which inhibited Mpro activity under in vitro conditions, were selected from the literature, and then screened through AutoDock Vina. The chemical features of the top 5 isatin derivatives with low binding energies (−8.5 to −8.2 kcal/mol) were used to screen similar types of compounds from several small-molecule libraries containing 15856508 compounds. A total of 1,609 compounds with similarity score ≥ 6 were screened and then subjected to docking as well as ADME analysis. Among the compounds screened, 4 ligands form Zinc drug-like library (ZINC000008848565, ZINC000009513563, ZINC000036759789 and ZINC000046053855) showed good ADMET properties, low binding energy (−8.4 to −8.6 kcal/mol), low interaction energy (−72.62 to −50.01 kcal/mol) and high structural stability with Mpro. Hence, the selected ligands might serve as the lead candidates for further wet laboratory validation, optimization and development. Communicated by Ramaswamy H. Sarma

description: In the spectral Petrov-Galerkin methods, the trial and test functions are required to satisfy particular boundary conditions. By a suitable linear combination of orthogonal polynomials, a basis, that is called the modal basis, is obtained. In this paper, we extend this idea to the non-orthogonal dual Bernstein polynomials. A compact general formula is derived for the modal basis functions based on dual Bernstein polynomials. Then, we present a Bernstein-spectral Petrov-Galerkin method for a class of time fractional partial differential equations with Caputo derivative. It is shown that the method leads to banded sparse linear systems for problems with constant coefficient. Some numerical examples are provided to show the efficiency and the spectral accuracy of the method.

description: Gradient fields can effectively suppress particle tunneling in a lattice and localize the wave function at all energy scales, a phenomenon known as Stark localization. Here, we show that Stark systems can be used as a probe for the precise measurement of gradient fields, particularly in the weak-field regime where most sensors do not operate optimally. In the extended phase, Stark probes achieve super-Heisenberg precision, which is well beyond most of the known quantum sensing schemes. In the localized phase, the precision drops in a universal way showing fast convergence to the thermodynamic limit. For single-particle probes, we show that quantum-enhanced sensitivity, with super-Heisenberg precision, can be achieved through a simple position measurement for all the eigenstates across the entire spectrum. For such probes, we have identified several critical exponents of the Stark localization transition and established their relationship. Thermal fluctuations, whose universal behavior is identified, reduce the precision from super-Heisenberg to Heisenberg, still outperforming classical sensors. Multiparticle interacting probes also achieve super-Heisenberg scaling in their extended phase, which shows even further enhancement near the transition point. Quantum-enhanced sensitivity is still achievable even when state preparation time is included in resource analysis.

description: We generalize the recently introduced Density-Matrix Renormalization Group (DMRG-X) [Khemani et al, PRL 2016] algorithm to obtain Floquet eigenstates of one-dimensional, periodically driven many-body localized systems. This generalization is made possible by the fact that the time-evolution operator for a period can be efficiently represented using a matrix-product operator. We first benchmark the method by comparing to exact diagonalization for small systems. We then obtain Floquet eigenstates for larger systems and show unambiguously that the characteristic area-law scaling remains robust.

Search for long-lived, massive particles in events with displaced vertices and multiple jets in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

Year: 2023
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for long-lived particles decaying into hadrons is presented. The analysis uses 139 fb$^{-1}$ of $pp$ collision data collected at $\sqrt{s} = 13$ TeV by the ATLAS detector at the LHC using events that contain multiple energetic jets and a displaced vertex. The search employs dedicated reconstruction techniques that significantly increase the sensitivity to long-lived particles decaying in the ATLAS inner detector. Background estimates for Standard Model processes and instrumental effects are extracted from data. The observed event yields are compatible with those expected from background processes. The results are used to set limits at 95% confidence level on model-independent cross sections for processes beyond the Standard Model, and on scenarios with pair-production of supersymmetric particles with long-lived electroweakinos that decay via a small $R$-parity-violating coupling. The pair-production of electroweakinos with masses below 1.5 TeV is excluded for mean proper lifetimes in the range from 0.03 ns to 1 ns. When produced in the decay of $m(\tilde{g})=2.4$ TeV gluinos, electroweakinos with $m(\tildeχ^0_1)=1.5$ TeV are excluded with lifetimes in the range of 0.02 ns to 4 ns.

description: SARS-CoV-2 outbreak in China in December 2019 and its spread as worldwide pandemic has been a major global health crisis. Extremely high infection and mortality rate has severely affected all sectors of life and derailed the global economy. While drug and vaccine development have been prioritized and have made significant progression, use of phytochemicals and herbal constituents is deemed as a low-cost, safer and readily available alternative. We investigated therapeutic efficacy of eight withanolides (derived from Ashwagandha) against the angiotensin-converting enzyme 2 (ACE2) proteins, a target cell surface receptor for SARS-CoV-2 and report results on the (i) computational analyses including binding affinity and stable interactions with ACE2, occupancy of ACE2 residues in making polar and nonpolar interactions with different withanolides/ligands and (2) in vitro mRNA and protein analyses using human cancer (A549, MCF7 and HSC3) cells. We found that among all withanolides, Withaferin-A, Withanone, Withanoside-IV and Withanoside-V significantly inhibited the ACE2 expression. Analysis of withanolides-rich aqueous extracts derived from Ashwagandha leaves and stem showed a higher ACE2 inhibitory potency of stem-derived extracts. Taken together, we demonstrated the inhibitory potency of Ashwagandha withanolides and its aqueous extracts against ACE2. Communicated by Ramaswamy H. Sarma

description: The Atlantic Rainforest biome, where fire events were originally less frequent, is now increasingly at risk of burning due to anthropogenic influences on the climate and landscape. Identifying fire patterns and their leading causes in tropical forests is essential to improve prevention and fire management. We applied a filtering algorithm to remove redundant heat signals from the National Institute for Space Research (INPE) fire foci database, generate fire density maps after validating the data, and build Random forest (RF) regression models to identify fire risk and the variables that best explain the fire patterns. Results showed high redundancy of heat signals and that the minimum detection size for fire scars was lower for forests than other land covers. Mean annual temperature higher than 22ºC was associated with a high risk of fire and tree cover greater than 80% with low fire risk. Our study reveals a fire pattern that can expose the last remnants of the Atlantic Rainforest in Rio de Janeiro to fire, including inside Protected Areas. HighlightsThe redundance in the fire foci dataset was ∼46%;Protected areas have alarmingly high densities of heat signals compared to the unprotected landscape;The minimum fire scar size detected was lower for forests than agriculture or grasslands land cover;Temperature higher than 22 °C was an important threshold to determine fire risk;High tree cover (>80%) characterized areas with the lowest densities of heat signals.

description: Models that connect galaxy and halo properties often summarize a halo's mass accretion history (MAH) with a single value, and use this value as the basis for predictions. However, a single-value summary fails to capture the complexity of MAHs and information can be lost in the process. We present MultiCAM, a generalization of traditional abundance matching frameworks, which can simultaneously connect the full MAH of a halo with multiple halo and/or galaxy properties. As a first case study, we apply MultiCAM to the problem of connecting dark matter halo properties to their MAHs in the context of a dark matter-only simulation. While some halo properties, such as concentration, are more strongly correlated to the early-time mass growth of a halo, others, like the virial ratio, have stronger correlations with late-time mass growth. This highlights the necessity of considering the impact of the entire MAH on halo properties. For most of the halo properties we consider, we find that MultiCAM models that use the full MAH achieve higher accuracy than conditional abundance matching models which use a single epoch. We also demonstrate an extension of MultiCAM that captures the covariance between predicted halo properties. This extension provides a baseline model for applications where the covariance between predicted properties is important.

description: Interface structure at polar/non-polar interfaces has been shown to be a key factor in controlling emergent behavior in oxide heterostructures, including the LaFeO$_3$/$\textit{n}$-SrTiO$_3$ system. We demonstrate via high energy resolution x-ray photoemission that epitaxial LaFeO$_3$/$\textit{n}$-SrTiO$_3$ (001) heterojunctions engineered to have opposite interface polarities exhibit very similar band offsets and potential gradients within the LaFeO$_3$ films. However, differences in the potential gradient within the SrTiO$_3$ layer depending on polarity may promote hole diffusion into LaFeO$_3$ for applications in photocatalysis.

description: The incurable Type 2 diabetes mellitus (T2DM) has now been considered a pandemic with only supportive care in existence. Due to the adverse effects of available anti-diabetic drugs, there arises a great urgency to develop new drug molecules. One of the alternatives that can be considered for the treatment of T2DM are natural compounds from traditionally used herbal medicine. The present study undertakes, an integrated multidisciplinary concept of Network Pharmacology to evaluate the efficacy of potent anti-diabetic compound from traditionally used anti-diabetic plants of north east India and followed by DFT analysis. In the course of the study, 22 plant species were selected on the basis of their use in traditional medicine for the treatment of T2DM by various ethnic groups of the north eastern region of India. Initially, a library of 1053 compounds derived from these plants was generated. This was followed by network preparation between compounds and targets based on the docking result. The compounds having the best network property were considered for DFT analysis. We have identified that auraptene, a monoterpene coumarin for its activity in the management of Type 2 diabetes mellitus and deciphered its unexplored probable mechanisms. Molecular dynamics simulation of the ligand–protein complexes also reveals the stable binding of auraptene with the target proteins namely, Protein Kinase C θ, Glucocorticoid receptor, 11-β hydroxysteroid dehydrogenase 1 and Aldose Reductase, all of which form uniform interactions throughout the MD simulation trajectory. Therefore, this finding could provide new insights for the development of a new anti-diabetic drug. Communicated by Ramaswamy H. Sarma

description: The spin supplementary conditions are constraints on spin degrees of freedom in classical relativity which restricts physical degrees of freedom to rotations. It is argued that the equivalent constraints in quantum field theory are the projection conditions on polarisation tensors, which remove timelike/longitudinal polarisations from the physical spectrum. The claim is supported by three examples of massive spinning particles coupled to electromagnetism: Dirac and Proca fields in quantum field theory, and $\mathcal{N} = 1$ worldline QFT for classical worldline theory. This suggests a resolution to the apparent discrepancy between effective field theory description of massive higher-spin fields~\cite{Bern:2020buy,Bern:2022kto} and post-Newtonian effective field theory of spinning classical particles~\cite{Levi:2015msa}, where the former admits more unfixed parameters compared to the latter; the additional parameters are fixed by projection conditions and therefore are not tunable parameters.

description: The structure of the lattice of clones on a finite set has been proven to be very complex. To better understand the top of this lattice, it is important to provide a characterization of submaximal clones in the lattice of clones. It is known that the clones $Pol(θ)$ and $Pol(ρ)$ (where $θ$ is a nontrivial equivalence relation on $E_k = \{0,\dots, k-1\}$, and $ρ$ is among the six types of relations which characterize maximal clones) are maximal clones. In this paper, we provide a classification of relations (of Rosenberg's List) on $E_k$ such that the clone $Pol(θ) \cap Pol(ρ)$ is maximal in $Pol(θ)$.

description: In response to the current pandemic caused by the novel SARS-CoV-2, we design new compounds based on Lopinavir structure as an FDA-approved antiviral agent which is currently under more evaluation in clinical trials for COVID-19 patients. This is the first example of the preparation of Lopinavir isosteres from the main core of Lopinavir conducted to various heterocyclic fragments. It is proposed that main protease inhibitors play an important role in the cycle life of coronavirus. Thus, the protease inhibition effect of synthesized compounds was studied by molecular docking method. All of these 10 molecules, showing a good docking score compared. Molecular dynamics (MD) simulations also confirmed the stability of the best-designed compound in Mpro active site. Communicated by Ramaswamy H. Sarma

For this purpose I will discuss in detail the emergence of the horizon condition and the Coulomb string tension. I will show that both are induced by center vortex gauge field configurations, which establish the connection between Gribov's confinement scenario and the center vortex picture of confinement. I will then extend the Hamiltonian approach to QCD in Coulomb gauge to finite temperatures, first by the usual grand canonical ensemble and second by the compactification of a spatial dimension. I will present results for the pressure, energy density and interaction measure as well as for the Polyakov loop.

description: Providing generalization guarantees for modern neural networks has been a crucial task in statistical learning. Recently, several studies have attempted to analyze the generalization error in such settings by using tools from fractal geometry. While these works have successfully introduced new mathematical tools to apprehend generalization, they heavily rely on a Lipschitz continuity assumption, which in general does not hold for neural networks and might make the bounds vacuous. In this work, we address this issue and prove fractal geometry-based generalization bounds without requiring any Lipschitz assumption. To achieve this goal, we build up on a classical covering argument in learning theory and introduce a data-dependent fractal dimension. Despite introducing a significant amount of technical complications, this new notion lets us control the generalization error (over either fixed or random hypothesis spaces) along with certain mutual information (MI) terms. To provide a clearer interpretation to the newly introduced MI terms, as a next step, we introduce a notion of "geometric stability" and link our bounds to the prior art. Finally, we make a rigorous connection between the proposed data-dependent dimension and topological data analysis tools, which then enables us to compute the dimension in a numerically efficient way. We support our theory with experiments conducted on various settings.

We attribute their forms to the activation of various hydrogen bonds between glycine I, II, III molecules. In the case of pulse heating the pyroelectric signal is observed also in the paraelectric phase. The applied measurement method is relatively simple but precise and can be realized in most of dielectric measurements laboratories.

description: The recent outbreak of COVID-19 caused by a new human coronavirus called SARS-CoV-2, is continually causing worldwide human infections and deaths.The main protease (3CLpro), which plays a critical role in the life cycle of the virus, makes it an attractive target for the development of antiviral agents effective against coronaviruses (CoVs).Currently, there is no specific viral protein targeted therapeutics.Therefore, there is a need to investigate an alternative therapy which will prevent the spread of the infection, by focusing on the transmission of the virus.Chlorhexidine (CHX) and flavonoids agents have shown that they have a viral inactivation effect against enveloped viruses, and thus facilitate the struggle against oral transmission.Especially, some flavonoids have very strong antiviral activity in SARS-CoV and MERS-CoV main protease.This study was conducted to evaluate the CHX and flavonoids compounds potential antiviral effects on SARS-CoV-2 main protease through virtual screening for the COVID-19 treatment by molecular docking method.According to the results of this study, CHX, Kaempferol-3-rutinoside, Rutin, Quercetin 3-beta-D-glucoside and Isobavachalcone exhibited the best binding affinity against this enzyme, and also these compounds showed significant inhibitory effects compared to the SARS-CoV-2 main protease crystal structure inhibitor (N3).Especially, these compounds mainly interact with His41, Cys145, His163, Met165, Glu166 and Thr190 in SARS-CoV-2 main protease binding site. Further, MD simulation analysis also confirmed that stability of these interactions between the enzyme and these five compounds.The current study provides to guide clinical trials for broad-spectrum CHX and bioactive flavonoids to reduce the viral load of the infection and possibly disease progression.

Успенский Тихвинский монастырь

description: Одним из источников для составления расходных денежных книг Успенского Тихвинского монастыря 1623–1633 гг. являются росписи расходов монастырских старцев и слуг в поездках в административные центры — Москву и Великий Новгород. Эти документы содержат ценные сведения о поводах обращения монастыря в органы власти и характере его взаимоотношений с должностными лицами, уплате налогов, обустройстве монастырских подворий в городах, ассортименте приобретаемых в поездках товаров и многом другом. В связи с тем, что архив монастыря за первую половину XVII в. понес значительные утраты, познакомиться с содержанием большинства росписей расходов в поездках позволяют монастырские денежные расходные книги, в которые они копировались. В статье на основе сравнительного анализа имеющихся росписей и их копий в расходных денежных книгах установлен характер редактирования включенных документов и степень полноты отражения в них данных оригиналов. Сделан вывод о том, что содержание росписей, скопированных в расходные книги, в целом соответствует текстам сохранившихся росписей, написанных столбцом в расходной части и позволяет использовать их данные для подсчетов статей монастырского денежного расхода.

description: Management of chronic diseases such as heart failure, diabetes, and chronic obstructive pulmonary disease (COPD) is a major problem in health care. A standard approach that the medical community has devised to manage widely prevalent chronic diseases such as chronic heart failure (CHF) is to have a committee of experts develop guidelines that all physicians should follow. These guidelines typically consist of a series of complex rules that make recommendations based on a patient's information. Due to their complexity, often the guidelines are either ignored or not complied with at all, which can result in poor medical practices. It is not even clear whether it is humanly possible to follow these guidelines due to their length and complexity. In the case of CHF management, the guidelines run nearly 80 pages. In this paper we describe a physician-advisory system for CHF management that codes the entire set of clinical practice guidelines for CHF using answer set programming. Our approach is based on developing reasoning templates (that we call knowledge patterns) and using these patterns to systemically code the clinical guidelines for CHF as ASP rules. Use of the knowledge patterns greatly facilitates the development of our system. Given a patient's medical information, our system generates a recommendation for treatment just as a human physician would, using the guidelines. Our system will work even in the presence of incomplete information. Our work makes two contributions: (i) it shows that highly complex guidelines can be successfully coded as ASP rules, and (ii) it develops a series of knowledge patterns that facilitate the coding of knowledge expressed in a natural language and that can be used for other application domains. This paper is under consideration for acceptance in TPLP.

description: We use a q-series identity by Ramanujan to give a combinatorial interpretation of Ramanujan's tau function which involves t-cores and a new class of partitions which we call (m,k)-capsids. The same method can be applied in conjunction with other related identities yielding alternative combinatorial interpretations of the tau function.

description: Intrinsically disordered regions (IDRs) in proteins are characterized by their flexibilities and low complexity regions, which lack unique 3 D structures in solution. IDRs play a significant role in signaling, regulation, and binding multiple partners, including DNA, RNA, and proteins. Although various experiments have shown the role of disordered regions in binding with RNA, a detailed computational analysis is required to understand their binding and recognition mechanism. In this work, we performed molecular dynamics simulations of 10 protein–RNA complexes to understand the binding governed by intrinsically disordered regions. The simulation results show that most of the disordered regions are important for RNA-binding and have a transition from disordered-to-ordered conformation upon binding, which often contribute significantly towards the binding affinity. Interestingly, most of the disordered residues are present at the interface or located as a linker between two regions having similar movements. The DOT regions are overlaped or flanked with experimentally reported functionally important residues in the recognition of protein-RNA complexes. This study provides additional insights for understanding the role and recognition mechanism of disordered regions in protein–RNA complexes. Communicated by Ramaswamy H. Sarma

description: In this paper, we propose a transmission mechanism for a reconfigurable intelligent surface (RIS)-assisted millimeter wave (mmWave) system based on cluster index modulation (CIM), named best-gain optimized cluster selection CIM (BGCS-CIM). The proposed BGCS-CIM scheme considers effective cluster power gain and spatial diversity gain obtained by the additional paths within the indexed cluster to construct an efficient codebook. We also integrate the proposed scheme into a practical system model to create a virtual path between transmitter and receiver where the direct link has been blocked. Thanks to the designed whitening filter, a closed-form expression for the upper bound on the average bit error rate (ABER) is derived and used to validate the simulation results. It has been shown that the proposed BGCS-CIM scheme outperforms the existing benchmarks thanks to its higher effective cluster gain, spatial diversity of indexed clusters, and lower inter-cluster interference.

description: We propose a mechanism for the enhancement of vacuum fluctuations by means of a classical field. The basic idea is that if an observable quantity depends quadratically upon a quantum field, such as the electric field, then the application of a classical field produces a cross term between the classical and quantum fields. This cross term may be significantly larger than the purely quantum part, but also undergoes fluctuations driven by the quantum field. We illustrate this effect in a model for lightcone fluctuations involving pulses in a nonlinear dielectric. Vacuum electric field fluctuations produce fluctuations in the speed of a probe pulse, and form an analog model for quantum gravity effects. If the material has a nonzero third-order susceptibility, then the fractional light speed fluctuations are proportional to the square of the fluctuating electric field. Hence the application of a classical electric field can enhance the speed fluctuations. We give an example where this enhancement can be an increase of one order of magnitude, increasing the possibility of observing the effect.

description: Neutrinos allow the probing of stellar interiors during core collapse, helping to understand the different stages and processes in the collapse. To date, supernova neutrinos have only been detected from a single event, SN1987A. Most studies from then on have focused on two distance extremes; Galactic/local supernovae and all past cosmic supernovae forming the diffuse supernova neutrino background. We focus on the intermediate distance regime as a target for detecting core-collapse supernova neutrinos at next generation detectors like Hyper-Kamiokande. To quantify the significance of neutrino detections, we draw on expected discoveries by surveys of near galaxies as well as large synoptic surveys to monitor for optical counterparts of core-collapse supernovae. We find that detection prospects require approximately ten years of operation. We discuss how the ability of electromagnetic surveys to pinpoint the time of core collapse to within the timescale of hours is key for confident neutrino detections. Transient surveys like DLT40 which frequently observe nearby galaxies can help with such crucial information.
