description: A systematic procedure to consistently formulate a field theoretical, QCD bound state problem with a fixed number of constituents is outlined. The approach entails applying the Hamiltonian flow equations, which are a set of continuous unitary transformations, to a QCD motivated Hamiltonian with a confining interaction. The method is developed in detail for gluodynamics in the Coulomb gauge to obtain an effective block-diagonal Hamiltonian appropriate to a reduced Fock space with fixed number of dynamical gluons. Standard many-body techniques are used to numerically diagonalize this Hamiltonian in a constituent two gluon Fock space. The calculated gluon condensates and glueball masses are in good agreement with QCD sum rule and lattice results.

description: The limitations that have inundated mainstream anticryptosporidials have necessitated the exploration of alternative approaches towards the design of novel anticryptosporidials with improved therapeutic activity. We virtually screened a dedicated library of 107,000 natural compounds available in the ZINC database against Cryptosporidium parvum inosine monophosphate dehydrogenase-NAD+ binding site. The top three compounds identified with the best complementarity to the CpIMPDH-NAD+ binding site included ZINC5225833, ZINC4258873, and ZINC3841381. Estimation of the total binding free energy using Molecular Mechanics Generalized Poisson Boltzmann Surface Area (MM/PBSA) method had the three compounds eliciting favourable binding free energies. ZINC3841381 had the best binding free energy of −58.43 kcal/mol followed by ZINC4258873 with −51.1 kcal/mol and ZINC5225833, −38.04 kcal/mol. The binding of the natural compounds to CpIMPDH induced structural perturbations in the protein compared to the apo. We evaluated the compliance of the natural compounds to Lipinski's rule of 5 and other pharmacokinetic parameters. From this evaluation, the natural compounds are drug-likely but can still make do with some modifications to improve their therapeutic potentials. The results obtained from this study can serve as a preliminary background in the further experimental exploration of ZINC5225833, ZINC4258873, and ZINC3841381 as potential anticryptosporidials.

description: With the increased deployment of machine learning models in various real-world applications, researchers and practitioners alike have emphasized the need for explanations of model behaviour. To this end, two broad strategies have been outlined in prior literature to explain models. Post hoc explanation methods explain the behaviour of complex black-box models by identifying features critical to model predictions; however, prior work has shown that these explanations may not be faithful, in that they incorrectly attribute high importance to features that are unimportant or non-discriminative for the underlying task. Inherently interpretable models, on the other hand, circumvent these issues by explicitly encoding explanations into model architecture, meaning their explanations are naturally faithful, but they often exhibit poor predictive performance due to their limited expressive power. In this work, we identify a key reason for the lack of faithfulness of feature attributions: the lack of robustness of the underlying black-box models, especially to the erasure of unimportant distractor features in the input. To address this issue, we propose Distractor Erasure Tuning (DiET), a method that adapts black-box models to be robust to distractor erasure, thus providing discriminative and faithful attributions. This strategy naturally combines the ease of use of post hoc explanations with the faithfulness of inherently interpretable models. We perform extensive experiments on semi-synthetic and real-world datasets and show that DiET produces models that (1) closely approximate the original black-box models they are intended to explain, and (2) yield explanations that match approximate ground truths available by construction.

description: The key purpose of this experiment was to evaluate the thrombolytic, antioxidant, membrane stabilizing and antimicrobial potentials of crude ethanol extracts (CEE) of whole plant, organic and aqueous soluble fractions (OF & AQSF). CEE showed the highest (44.63%) clot lysis activity compared to streptokinase (64.35%). In DPPH study, petroleum ether soluble fraction (PSF) has exhibited IC50 of 18.83 μg/mL while the standard ascorbic acid was 2.48 µg/mL. AQSF profoundly inhibited the lysis of erythrocytes (66.20%) which was insignificantly different (p > 0.05) to acetylsalicylic acid (71.98%), the reference. However, AQSF showed a significantly stronger level of protection against heat-induced hemolysis (64.80%) as compared with the acetylsalicylic acid (78.90%). CEE, OF and AQSF have displayed reasonable growth of inhibition of tested bacteria compared to negative control and standard drug (77.50 mg of GAE/g).

description: Cross-domain recommendation (CDR) is a task that aims to improve the recommendation performance in a target domain by leveraging the information from source domains. Contrastive learning methods have been widely adopted among intra-domain (intra-CL) and inter-domain (inter-CL) users/items for their representation learning and knowledge transfer during the matching stage of CDR. However, we observe that directly employing contrastive learning on mixed-up intra-CL and inter-CL tasks ignores the difficulty of learning from inter-domain over learning from intra-domain, and thus could cause severe training instability. Therefore, this instability deteriorates the representation learning process and hurts the quality of generated embeddings. To this end, we propose a novel framework named SCCDR built up on a separated intra-CL and inter-CL paradigm and a stop-gradient operation to handle the drawback. Specifically, SCCDR comprises two specialized curriculum stages: intra-inter separation and inter-domain curriculum scheduling. The former stage explicitly uses two distinct contrastive views for the intra-CL task in the source and target domains, respectively. Meanwhile, the latter stage deliberately tackles the inter-CL tasks with a curriculum scheduling strategy that derives effective curricula by accounting for the difficulty of negative samples anchored by overlapping users. Empirical experiments on various open-source datasets and an offline proprietary industrial dataset extracted from a real-world recommender system, and an online A/B test verify that SCCDR achieves state-of-the-art performance over multiple baselines.

description: The structure and substitution energies of dichlorotris(triphenylphosphine)ruthenium(II) complex, [RuCl2(PPh3)3], was computed with ten different methods at the density functional theory level using a composition of basis sets. The PBE0 functional led to the best description of bond lengths, while the MN12-L functional yielded the best results for bond angles. For calculation of the Ru-P bond dissociation energies, the best results were obtained with the M06-L functional. The nature of the Ru-P bond was discussed in terms of donation and back-donation as well as in terms of the steric versus covalent contributions to the bonding. In the square pyramidal structure, the apical Ru-P bond is considerably tighter than the basal Ru-P bonds. This is due to an interaction of the apical PPh3 ligand with a high d character orbital on the Ru atom, favouring back-donation, leading to a short Ru-P distance and strong bonding energy. Additionally, we also investigated the equilibrium structures and mechanism for the substitution of one of the PPh3 group by the piperidine molecule. The equilibrium between the several species involved in the substitution process indicates that addition of the piperidine molecule to [RuCl2(PPh3)3] followed by elimination of a PPh3 unity is the pathway with lower energy.

description: We apply a multi-phase transport (AMPT) model to study two-particle angular correlations in $pp$ collisions at $\sqrt{s}= 7$ TeV. Besides being able to describe the angular correlation functions of meson-meson pairs, a large improvement for the angular correlations of baryon-baryon and antibaryon-antibaryon is achieved. We further find that the AMPT model with new quark coalescence provides an even better description on the anti-correlation feature of baryon-baryon correlations observed in the experiments. We also extend the study to p-Pb collisions at $\sqrt{s}= 5.02$ TeV and obtained similar results. These results help us better understand the particle production mechanism in $pp$ and p-Pb collisions at LHC energies.

description: We present a new approach which employs a deep neural network to obtain parameters of analytical representation of potential energy curve of diatomic molecule. We test the approach to find spectroscopic characteristics for the ground X2Σ+ electronic state of MgF molecule based on the experimental energies of ro-vibrational transitions. The result shows that a deep neural network can be applied in characterisation of interatomic potential of diatomic molecule. Our approach is competitive with those obtained using other methods tested, i.e. shallow neural network and the so-called brute force method.

description: In the field of quantum computation and communication there is a compelling need for quantum-coherent frequency conversion between microwave electronics and infra-red optics. A promising platform for this is an optomechanical crystal resonator that uses simultaneous photonic and phononic crystals to create a co-localized cavity coupling an electromagnetic mode to an acoustic mode, which then via electromechanical interactions can undergo direct transduction to electronics. The majority of work in this area has been on one-dimensional nanobeam resonators which provide strong optomechanical couplings but, due to their geometry, suffer from an inability to dissipate heat produced by the laser pumping required for operation. Recently, a quasi-two-dimensional optomechanical crystal cavity was developed in silicon exhibiting similarly strong coupling with better thermalization, but at a mechanical frequency above optimal qubit operating frequencies. Here we adapt this design to gallium arsenide, a natural thin-film single-crystal piezoelectric that can incorporate electromechanical interactions, obtaining a mechanical resonant mode at f_m ~ 4.5 GHz ideal for superconducting qubits, and demonstrating optomechanical coupling g_om/(2pi) ~ 650 kHz.

description: Based on 1-phenylpyrrolidine (PT) dye, six new metal-free organic molecules S1–S6, containing PT as donor (D) connected through different linkages (π) and cyanoacrylic acid as acceptor (A), were designed and studied for dye sensitised solar cells (DSSCs). In this paper, D-π-A system of S1–S6 dye molecules was investigated by quantum chemical calculations to inspect the optical absorption properties and photovoltaic (PV) parameters. In particular, there are applied three long-range corrected (LC) functionals, such as B3PW91, CAM-B3LYP and ωB97XD with the time-dependent DFT (TD-DFT) calculation to systematically investigate the absorption peak in PT dye. From the calculated results, CAM-B3LYP functional was a good match with the PT dye. Therefore, the S1–S6 molecules’ optical absorption spectra have been computed by using the CAM-B3LYP/6-31+G(d) theory. The conductor-like polarisable continuum model (C-PCM) results show that the precise absorption spectra have attained solvent effect included in the excited state geometries. The frontier molecular orbitals (FMOs) of the HOMOs and LUMOs energies of S1–S6 derivatives confirm positive results on the dye regeneration and electron injection processes. The outcomes display that the benzo[c][1,2,5]thiadizole (S4) and benzo[c][1,2,5]oxadizole (S5) molecules are the most suitable spacers for D to A, owing to longer absorption peaks and revealing red-shifted optical absorption.

description: Molecular-dynamics simulations have been performed for full liquid water adsorbed onto two planar silicon surfaces, with varying hydrogen- and hydroxyl-termination (mimicking different extents of hydrophobicity and hydrophophilicity). It was found that there was water-density ‘ordering’ perpendicular to both surfaces – heavily dependent on the degree of hydrophobicity. The position and the width of the three solvation layers closest to the different surfaces depends, again, on the hydrophobicity of the surface. IR spectra of the first monolayer of adsorbed water indicate similarities to more confined-water dynamical behaviour, but without becoming ice-like. Moving away from the surface, the water behaviour converges on that of liquid water, albeit with some intermediate characteristics; this was seen for both hydro-phobic and –philic surfaces.

description: The dynamics of interference over space and time influences the performance of wireless communication systems, yet its features are still not fully understood. This article analyzes the temporal dynamics of the interference in Poisson networks accounting for three key correlation sources: the location of nodes, the wireless channel, and the network traffic. We derive expressions for the auto-correlation function of interference. These are presented as a framework that enables us to arbitrarily combine the three correlation sources to match a wide range of interference scenarios. We then introduce the interference coherence time - analogously to the well-known channel coherence time - and analyze its features for each correlation source. We find that the coherence time behaves very different for the different interference scenarios considered and depends on the network parameters. Having accurate knowledge of the coherence time can thus be an important design input for protocols, e.g., retransmission and medium access control.

description: We study a special class of topological phase transitions in two dimensions described by the inversion of bands with relative angular momentum higher than 1. A band inversion of this kind, which is protected by rotation symmetry, separates the trivial insulator from a Chern insulating phase with higher Chern number, and thus generalizes the quantum Hall transition described by a Dirac fermion. Higher angular momentum band inversions are of special interest, as the non-vanishing density of states at the transition can give rise to interesting many-body effects. Here we introduce a series of minimal lattice models which realize higher angular momentum band inversions. We then consider the effect of interactions, focusing on the possibility of electron-hole exciton condensation, which breaks rotational symmetry. An analysis of the excitonic insulator mean field theory further reveals that the ground state of the Chern insulating phase with higher Chern number has the structure of a multicomponent integer quantum Hall state. We conclude by generalizing the notion of higher angular momentum band inversions to the class time-reversal invariant systems, following the scheme of Bernevig-Hughes-Zhang (BHZ). Such band inversions can be viewed as transitions to a topological insulator protected by rotation and inversion symmetry, and provide a promising venue for realizing correlated topological phases such as fractional topological insulators.

description: We apply the Glasgow method for lattice QCD at finite chemical potential to a schematic random matrix model (RMM). In this method the zeros of the partition function are obtained by averaging the coefficients of its expansion in powers of the chemical potential. In this paper we investigate the phase structure by means of Glasgow averaging and demonstrate that the method converges to the correct analytically known result. We conclude that the statistics needed for complete convergence grows exponentially with the size of the system, in our case, the dimension of the Dirac matrix. The use of an unquenched ensemble at $μ=0$ does not give an improvement over a quenched ensemble. We elucidate the phenomenon of a faster convergence of certain zeros of the partition function. The imprecision affecting the coefficients of the polynomial in the chemical potential can be interpeted as the appearance of a spurious phase. This phase dominates in the regions where the exact partition function is exponentially small, introducing additional phase boundaries, and hiding part of the true ones. The zeros along the surviving parts of the true boundaries remain unaffected.

description: We construct supergravity solutions describing branes (D2-branes or NS5-branes or waves) localized within D6-branes in the region close to the core of the D6-branes. Other similar string-theory and M-theory `near-core' localized solutions can be found by applying U-duality and/or lifting D=10 solutions to D=11. In particular, the D2-branes localized on D6-branes is T-dual to a special case of the background describing (D)strings localized on (D)5-branes and thus is also related to a localized intersection of M2-branes and M5-branes. D6+wave configuration is U-dual to a D0-brane localized on a Kaluza-Klein 5-brane or to the fundamental string intersecting a D5-brane with the point of intersection localized on the D5-brane.

description: Dense environments hosting compact binary mergers can leave an imprint on the gravitational-wave emission which, in turn, can be used to identify the characteristics of the environment. To demonstrate such scenario, we consider a simple setup of binary black holes with an environment consisting of a scalar-field bubble. We use this as a proxy for more realistic environments and as an example of the simplest physics beyond the standard model. We perform Bayesian inference on the numerical relativity waveforms using state-of-the-art waveform templates for black-hole mergers. In particular, we perform parameter estimation and model selection on signals from black-hole mergers with different mass ratios, total mass and loudness, and hosted by scalar-field bubbles of varying field amplitude. We find that sub-dominant gravitational wave modes emitted during the coalescence and ringdown are key to identifying environmental effects. In particular, we find that for face-on signals dominated by the quadrupole mode, the environment is only detectable if both the ringdown and the late inspiral/early merger fall in the detector band, so that inconsistencies can be found between the inferred binary parameters and those of the final black hole. For edge-on mergers we find that the environment can be detected even if only the ringdown is in band, thanks to the information encoded in the quasi-normal mode structure of the final black-hole.

description: Using WFPC2 on the Hubble Space Telescope, we have isolated a sample of 258 white dwarfs (WDs) in the Galactic globular cluster M4. Fields at three radial distances from the cluster center were observed and sizeable WD populations were found in all three. The location of these WDs in the color-magnitude diagram, their mean mass of 0.51($ \pm 0.03$)M$_{\odot}$, and their luminosity function confirm basic tenets of stellar evolution theory and support the results from current WD cooling theory. The WDs are used to extend the cluster main-sequence mass function upward to stars that have already completed their nuclear evolution. The WD/red dwarf binary frequency in M4 is investigated and found to be at most a few percent of all the main-sequence stars. The most ancient WDs found are about 9 Gyr old, a level which is set solely by the photometric limits of our data. Even though this is less than the age of M4, we discuss how these cooling WDs can eventually be used to check the turnoff ages of globular clusters and hence constrain the age of the Universe.

- [[worker]]. Noir avec l'extremite des antennes et des mandibules, les eperons et les tarses ferrugineux; assez luisant, avec un reflet bleu provenant d'une sculpture microscopique, invisible a la loupe. La sculpture visible consiste en petits points, portant des poils dresses courts et fins et la pubescence, celle-ci limitee au devant de la tete, aux scapes et aux pattes, nulle ailleurs. Tete plus longue que large, a cotes paralleles, un peu sinues de chaque cote en avant, arrondie derriere; yeux grands, peu convexes, places vers le milieu de la longueur. Epistome carene, finement strie, mandibules assez etroites a la base, graduellement elargies vers le bout, avec le bord terminal tranchant, formant avec le bord interne un angle arrondi, finissant en pointe un peu recourbee; elles sont rayees d'un sillon oblique qui part de la base, croise le bord externe qui parait inflechi en cet endroit et se porte le long de ce bord vers la pointe. Antennes allongees, 2 e article du funicule environ deux fois aussi long que le precedent. Dos du thorax offrant, sur le profil, un angle rentrant a l'endroit de la suture meso-metanotale; le metanotum bien plus long que le pronotum et le mesonotum, pris ensemble; face declive avec quelques rides transversales; chez quelques exemplaires, le dos de ce segment est marque en arriere d'une impression longitudinale. Ecaille a peu pres aussi large que longue, arrondie en avant, tronquee derriere, avec le bord de la troncature fortement emousse. Etranglement entre les deux segments suivants peu marque. Pattes finement ponctuees, assez mates.
Long. 10 - 11 mill.
Diego-Suarez. - L'ecaille massive et la sculpture faible a reflet bleu distinguent cette espece de ses nombreux congeneres. Le meme reflet bleu se retrouve chez plusieurs autres especes, mais elles ont le pedicule autrement conforme.

description: We present a new approach which employs a deep neural network to obtain parameters of analytical representation of potential energy curve of diatomic molecule. We test the approach to find spectroscopic characteristics for the ground X2Σ+ electronic state of MgF molecule based on the experimental energies of ro-vibrational transitions. The result shows that a deep neural network can be applied in characterisation of interatomic potential of diatomic molecule. Our approach is competitive with those obtained using other methods tested, i.e. shallow neural network and the so-called brute force method.

description: Single-molecule stretching experiments on DNA, RNA, and other biological macromolecules opened up the possibility of an impressive progress in many fields of Life and Medical sciences. The reliability of such experiments may be crucially limited by the possibility of determining the influence of the apparatus on the experimental outputs. Here we deduce an analytical model that we show to be coherent with previous numerical results and that quantitively reproduce AFM experimental tests on titin macromolecules and P-selectin AFM experiments with variable probe stiffnesses. We believe that the obtained analytical description can represent an important step forward in the interpretation of Single Molecule Force Spectroscopy experiments and intermolecular interactions phenomena.

description: Based on 1-phenylpyrrolidine (PT) dye, six new metal-free organic molecules S1–S6, containing PT as donor (D) connected through different linkages (π) and cyanoacrylic acid as acceptor (A), were designed and studied for dye sensitised solar cells (DSSCs). In this paper, D-π-A system of S1–S6 dye molecules was investigated by quantum chemical calculations to inspect the optical absorption properties and photovoltaic (PV) parameters. In particular, there are applied three long-range corrected (LC) functionals, such as B3PW91, CAM-B3LYP and ωB97XD with the time-dependent DFT (TD-DFT) calculation to systematically investigate the absorption peak in PT dye. From the calculated results, CAM-B3LYP functional was a good match with the PT dye. Therefore, the S1–S6 molecules’ optical absorption spectra have been computed by using the CAM-B3LYP/6-31+G(d) theory. The conductor-like polarisable continuum model (C-PCM) results show that the precise absorption spectra have attained solvent effect included in the excited state geometries. The frontier molecular orbitals (FMOs) of the HOMOs and LUMOs energies of S1–S6 derivatives confirm positive results on the dye regeneration and electron injection processes. The outcomes display that the benzo[c][1,2,5]thiadizole (S4) and benzo[c][1,2,5]oxadizole (S5) molecules are the most suitable spacers for D to A, owing to longer absorption peaks and revealing red-shifted optical absorption.
Finite System Size Correction to the Effective Coupling in $ϕ^4$ Scattering

description: We compute and explore numerically the finite system size correction to NLO $2\to2$ scattering in massive scalar $ϕ^4$ theory. The derivation uses "denominator regularization" (instead of the usual dimensional regularization) on a spacetime with spatial directions compactified to a torus, with characteristic lengths not necessarily of equal size. We determine a useful analytic continuation of the generalized Epstein zeta function to isolate the usual UV divergence. Self-consistently, the renormalized finite system size correction reduces to zero as the system size goes to infinity and, further, satisfies the optical theorem. One of our checks of unitarity leads to a generalization of a number theoretic result from Hardy and Ramanujan. Precise numerical exploration of the finite system size correction to the amplitude and coupling when two spatial dimensions are finite requires the exploitation of the analytic structure of the finite system size result via a dispersion relation. We find that the finite system size scattering amplitude exhibits "geometric" bound states. Even away from these bound states, the finite system size correction to the effective coupling can be large.

description: We perform a semi-classical study of chiral symmetry breaking and of the spectrum of the Dirac operator in QCD with adjoint fermions. For this purpose we calculate matrix elements of the adjoint Dirac operator between instanton zero modes and study their symmetry properties. We present simulations of the instanton ensemble for different numbers of Majorana fermions in the adjoint representation. These simulations provide evidence that instantons lead to gluino condensation in supersymmetric gluodynamics.
