description: We explore the spin density and charge currents arising on the surface of a topological insulator and in a 2D Rashba metal due to magnetization gradients. For topological insulators a single interconversion coefficient controls the generation of both quantities. This coefficient is quantized to a value proportional to the vorticity of the Dirac point which constitutes a hallmark of parity anomaly at finite density. As such, it also unveils a robust route to disentangle and detect the protected states of a topological insulator on a given surface. In stark contrast, Rashba metals do not exhibit such anomalies since they contain an even number of helical branches. Nonetheless, also these are governed by quantized responses which, however, are not protected against weak disorder. Furthermore, we find that for Rashba metals the interconversion coefficients demonstrate discontinuities and a nontrivial interplay upon varying the chemical potential, the strength of the spin-orbit coupling, and a pairing gap. Our results have implications for the binding between magnetic skyrmions and superconducting vortices, the emergence of Majorana zero modes, and pave the way for superconducting diode effects mediated by out-of-plane magnetization gradients.

Publisher: name: Zenodo
Year: 2018

description: Insee has made a heavy use of DDI 3.2 for several years, especially the data collection and logical product parts.

Although DDI 3.2 is a major enhancement from DDI 3.1 and has proven to be quite complete, some specific features were considered as missing by Insee. They were then reported back to the DDI Technical Committee over the course of years.

This presentation will:

	Describe the interaction process between the DDI Technical Committee and Insee
	Give an overview of the different requests for change issued by Insee
	Depict which ones were integrated in DDI 3.3 and were not, and the reasons why
	Outline the process Insee intends to set up to integrate the official DDI 3.3 schemas as soon as they are published.

description: Quantum mechanical theory disallows the model that has been used to infer the neutrino mass difference from the reported "GSI oscillations" in the rates of decay of hydrogen-like ions by electron capture. It has not been proved that the existence of mass-difference-dependent oscillations conflicts with quantum mechanics but no consistent quantum mechanical model has been shown to predict them.

description: Background: Antimicrobial resistance (AMR) is one of the main threats to global health. The dissemination of mobile colistin resistance genes (mcr) is a major concern affecting humans, animals and environment. Food-producing animals are considered the main reservoir of mcr genes, however the role of wild animals and pets is less studied. Here, we investigate the mcr occurrence among wild animals, wild birds, food-producing animals and pets. Material & Methods: Between 2019-2021, faecal samples obtained from wild animals (boars, N=39; deer, N=62; other, N=6), wild birds (N=98), food-producing animals (cattle, N=40; pigs, N=56) and pets (cats and dogs, N=199). Isolation was performed in selective and non-selective medium, followed by identification of virulence genes of E. coli by PCR, and Salmonella serotyping. The mcr 1-5 genes were screened by PCR in all E. coli and Salmonella isolates recovered. Whole-genome sequencing was used to investigate the presence of AMR genes, multilocus sequence type and phylogeny of all pathogenic isolates, as well as mcr-carrying isolates. Results: The overall occurrence rate of E.coli and Salmonella was 77.8% (389/500) and 2.8% (14/500), respectively. Pathogenic E.coli was detected in 46.7% (50/107) of wild animals, 2.0% (2/98) of wild birds, 11.4% (11/96) of food-producing animals and 19.1% (38/199) of pets, while Salmonella was identified in 2.8% of wild animals (3/107), 3.1% (3/98) of wild birds, and 7.3% (7/96) of food-producing animals. The mcr-1 gene was detected in 1.8% (7/389) of the E. coli positive samples, all of them in isolates recovered from pigs (13.7%; 7/51). All this mcr-1-positive showed additional resistance phenotypes, including MDR, and several virulence genes. No cases of mcr genes were identified in Salmonella isolates. Conclusions: Pathogenic E. coli was significantly more frequent than Salmonella spp in the studied animals. Besides the general low prevalence of the resistance to colistin mediated by mcr genes, the only cases were identified in E. coli food-producing isolates, namely in pigs. Our results highlight the importance of a continuous surveillance of antimicrobial resistance in an OneHealth approach.

description: At the present scenario of the internet, there exist many optimization techniques to improve the Web speed but almost expensive in terms of bandwidth. So after a long investigation on different techniques to compress the data without any loss, a new algorithm is proposed based on L Z 77 family which selectively models the references with backward movement and encodes the longest matches through greedy parsing with the shortest path technique to compresses the data with high density. This idea seems to be useful since the single Web Page contains many repetitive words which create havoc in consuming space, so let it removes such unnecessary redundancies with 70% efficiency and compress the pages with 23.75 - 35% compression ratio.
On Many-Actions Policy Gradient

description: We study the variance of stochastic policy gradients (SPGs) with many action samples per state. We derive a many-actions optimality condition, which determines when many-actions SPG yields lower variance as compared to a single-action agent with proportionally extended trajectory. We propose Model-Based Many-Actions (MBMA), an approach leveraging dynamics models for many-actions sampling in the context of SPG. MBMA addresses issues associated with existing implementations of many-actions SPG and yields lower bias and comparable variance to SPG estimated from states in model-simulated rollouts. We find that MBMA bias and variance structure matches that predicted by theory. As a result, MBMA achieves improved sample efficiency and higher returns on a range of continuous action environments as compared to model-free, many-actions, and model-based on-policy SPG baselines.

title: Exploring the Applications of PBPK Modelling to Optimise HIV-1 Treatment

Publisher: name: University of Liverpool Repository
Year: 2022

description: Human immunodeficiency virus (HIV-1) infection continues to be a significant public health concern, with 36.3 million lives being claimed by the infection thus far. Currently there is no cure for HIV. Antiretroviral (ARV) therapy has considerably increased life expectancy in people living with HIV (PLWH), however, several challenges remain. This thesis investigates the various ways in which physiologically based pharmacokinetic (PBPK) modelling can be developed and applied with the aim of optimising treatment for human immunodeficiency virus (HIV-1) infection. Neonatal patients are considered a vulnerable population as limited clinical studies are conducted in this population. Newborns born to mothers with HIV are at risk of receiving HIV. Lack of pharmacokinetic (PK) data means fewer treatment options are available. Chapters 2 & 3 focus on developing and applying a neonatal PBPK model to investigate the PK of integrase inhibitors, dolutegravir and bictegravir in neonates. Chapter 4 goes on to describe how modelling can be used to predict the PK of novel formulations by simulating long-acting, intramuscular, cabotegravir in neonates. Polypharmacy is routinely observed in PLWH, and drug-drug interactions (DDIs) prove an obstacle in HIV treatment, Chapter 5 involved developing an adult PBPK model to evaluate the magnitude of moderate inducers on novel ARVs. Residual levels of viraemia hinder the ability to develop a cure, Chapter 6 investigated the penetration of ARV drugs in lymphoid tissues using a mechanistic lymphatic PBPK model. Understanding the penetration of drugs in target tissues can help optimise ARV therapy. Collectively, this thesis evaluates the possible ways HIV treatment can be improved and optimised by investigating the potential of treatments in special populations, novel formulations of ARV drugs, management of drug-drug interactions and the penetration of therapy in target tissues.

description: Consumption of soft drinks with high potentially toxic elements concentrations may lead to acute or chronic poisoning. Soft drinks have been shown to contain traces of some potentially toxic elements such as cadmium, lead, mercury arsenic, zinc, etc. which may be due to environmental pollution from the surface and underground water, food and fruits utilised during production, and can be toxic for humans. In this study, Quadrupole Inductively Coupled Mass Spectrometer (Q-ICP-MS) was used in a simple validated method of analysis for direct determination of Al, Sb, As, Cd, Cr, Co, Cu, Fe, Pb, Mn, Hg, Ni, Sn, and Zn in soft drink samples. Analysis of 130 samples covering 14 different brands of popular soft drinks in Egypt to assess whether the intakes complied with the upper permissible levels for tested metals was performed. The results showed that all analysed samples were free from any detectable amount of Hg, while the mean concentrations, in µg/L, were as follows: 1.48 (Cr), 1.96 (As), 0.77 (Sb), 0.53 (Co), 20.27 (Mn), 108.83 (Fe), 0.52 (Cd), 13.18 (Cu), 8.55 (Ni), 20.00 (Sn), 80.09 (Al), 36.54 (Zn), and 1.05 (Pb). The health risk assessment was evaluated for estimated weekly intake, the hazard quotient, the hazard index and the target cancer risk using the Food and Nutrition Board, FAO/WHO and USEPA recommendations. The weekly intakes of all elements were found to be significantly below the recommended tolerable levels. Also, the hazard quotient, the hazard index and the target cancer values for all elements were found to be lower than acceptable guideline values, which indicated that there was no any non-carcinogenic or carcinogenic effects may occur.
Structural insights into the 3D genome folding and expression

description: Chromatin is the complex structure formed by the association of nuclear proteins and DNA. It brings about condensation and organisation of chromosomes during the cell cycle, enabling fundamental processes such as gene expression, recombination, DNA repair, and mitosis. A large number of protein complexes form a network within chromatin, carrying out different tasks and distinguishing the high versatility and dynamicity of this structure. My PhD project is centred around the structural and functional characterisation of three protein complexes that carry out fundamental chromosomal transactions. In the first part of my PhD project, I studied the assembly of the IFN‐β enhanceosome and the chromatin modifier p300 as a prototypical system to acquire insights into the molecular crosstalk that regulate transcription through enhancers. Moreover, I investigated different assemblies of the cohesin complex with its partners and the way these interactions determine specific roles in different cellular contexts. In particular, I studied two complexes formed by cohesin in association with two different factors that play key roles during mitosis and meiosis, respectively. By deepening the understanding of how these molecular machineries play their role in the three‐dimensional organisation of the genome it will be possible to broaden the knowledge of the complexity that lays behind essential cell activities like gene expression regulation, chromosomal alignment along the mitotic axis and recombination during meiosis.

description: A new Hubble Space Telescope observation of the 7:4 resonant transneptunian binary system (385446) Manwë has shown that, of two previously reported solutions for the orbit of its satellite Thorondor, the prograde one is correct. The orbit has a period of 110.18 $\pm$ 0.02 days, semimajor axis of 6670 $\pm$ 40 km, and an eccentricity of 0.563 $\pm$ 0.007. It will be viewable edge-on from the inner solar system during 2015-2017, presenting opportunities to observe mutual occultation and eclipse events. However, the number of observable events will be small, owing to the long orbital period and expected small sizes of the bodies relative to their separation. This paper presents predictions for events observable from Earth-based telescopes and discusses the associated uncertainties and challenges.

description: In this paper, a novel sorbent consisting of graphitic carbon nitride/polymer ionic liquid connected to halloysite nanotubes (g-C3N4-IL@HNT) was fabricated and used for benzene and phenol pollutant extraction from water samples. This mixed-mode sorbent contains multifunctional groups that allow interaction with several analytes, and because of its porosity, it can be embedded in a syringe device as the extractant without any filtration or centrifugation steps. A high-performance liquid chromatography-ultraviolet was used for the detection of analytes. The composition and morphology of the sorbent have been investigated by Fourier-transform infrared spectroscopy, scanning electron microscopy and energy-dispersive spectroscopy. In this work, parameters affecting the extraction methodology such as elution solvent and its volume, number of absorption cycles, number of solvent cycles, salt effect and matrix effect were investigated and optimised. Under the optimal conditions, a linear calibration curve was obtained in the range of 5–1000 μg L−1 (r2 > 0.996) with detection limits (S/N = 3) of 0.5–1 μg L−1. The g-C3N4-IL@HNT showed proper characteristics for the extraction of benzene and phenol pollutant residues in the environmental water samples with recoveries between 71% and 104.8% and the relative standard deviation of 6.6–8.6% (intra-day) and 9–11% (inter-day).

description: Semiconductor artificial graphene nanostructures where Hubbard model parameter $U/t$ can be of the order of 100, provide a highly controllable platform to study strongly correlated quantum many-particle phases. We use accurate variational and diffusion Monte Carlo methods to demonstrate a transition from antiferromagnetic to metallic phases for experimentally accessible lattice constant $a=50$ nm in terms of lattice site radius $ρ$, for finite sized artificial honeycomb structures nanopatterned on GaAs quantum wells containing up to 114 electrons. By analysing spin-spin correlation functions for hexagonal flakes with armchair edges and triangular flakes with zigzag edges, we show that edge type, geometry and charge nonuniformity affect the steepness and the crossover $ρ$ value of the phase transition. For triangular structures, the metal-insulator transition is accompanied with a smoother edge polarization transition.

description: We consider Hamiltonians of models describing non-relativistic quantum mechanical matter coupled to a relativistic field of bosons. If the free Hamiltonian has an eigenvalue, we show that this eigenvalue persists also for nonzero coupling. The eigenvalue of the free Hamiltonian may be degenerate provided there exists a symmetry group acting irreducibly on the eigenspace. Furthermore, if the Hamiltonian depends analytically on external parameters then so does the eigenvalue and eigenvector. Our result applies to the ground state as well as resonance states. For our results we assume a mild infrared condition. The proof is based on operator theoretic renormalization. It generalizes the method used in [15] to non-degenerate situations, where the degeneracy is protected by a symmetry group, and utilizes Schur's lemma from representation theory.

The distances of $11.11^{+0.79}_{-0.69}$ kpc to W49N (G043.16+0.01) and $10.75^{+0.61}_{-0.55}$ kpc to G048.60+0.02 locate them in a distant section of the Perseus arm near the solar circle in the first Galactic quadrant. This allows us to locate accurately the inner portion of the Perseus arm for the first time. Combining the present results with sources measured in the outer portion of the arm in the second and third quadrants yields a global pitch angle of 9.5 deg +/- 1.3 deg for the Perseus arm. We have found almost no H$_2$O maser sources in the Perseus arm for 50 deg $< \ell

description: Trading data through blockchain platforms is hard to achieve \textit{fair exchange}. Reasons come from two folds: Firstly, guaranteeing fairness between sellers and consumers is a challenging task as the deception of any participating parties is risk-free. This leads to the second issue where judging the behavior of data executors (such as cloud service providers) among distrustful parties is impractical in the context of traditional trading protocols. To fill the gaps, in this paper, we present a \underline{b}lockchain-based \underline{d}ata \underline{t}rading \underline{s}ystem, named BDTS. BDTS implements a fair-exchange protocol in which benign behaviors can get rewarded while dishonest behaviors will be punished. Our scheme requires the seller to provide consumers with the correct encryption keys for proper execution and encourage a rational data executor to behave faithfully for maximum benefits from rewards. We analyze the strategies of consumers, sellers, and dealers in the trading game and point out that everyone should be honest about their interests so that the game will reach Nash equilibrium. Evaluations prove efficiency and practicability.

description: The transverse momentum dependent nuclear modification factors (NMF), namely $R_{CP}$, is investigated for protons produced in Au + Au at 1$A$ GeV within the framework of the isospin-dependent quantum molecular dynamics (IQMD) model. It is found that the radial collective motion during the expansion stage affects the NMF at low transverse momentum a lot. By fitting the transverse mass spectra of protons with the distribution function from the Blast-Wave model, the magnitude of radial flow can be extracted. After removing the contribution from radial flow, the $R_{CP}$ can be regarded as a thermal one and is found to keep unitary at transverse momentum lower than 0.6 GeV/c and enhance at higher transverse momentum, which can be attributed to Cronin effect.

Die vorliegende Literaturarbeit vermittelt zum einen ein Überblickswissen zur Thematik von depressiven Störungen bei Kindern und Jugendlichen sowie deren Auswirkungen in der Schule. Zum anderen wurde mittels eines wissenschaftlichen Reviews untersucht, welche Risiko- und Schutzfaktoren im Schulalltag eine depressive Erkrankung bei den Lernenden beeinflussen und welche Präventions- und Interventionsmassnahmen eine positive Auswirkung auf die Befindlichkeit sowie das schulische Lernen der Schülerinnen und Schüler haben können. Um diese Fragen zu beantworten, wurden mithilfe einer qualitativen Inhaltsanalyse relevante Informationen aus 11 empirischen Studien und einem Review systematisch extrahiert. Aus der Analyse ging hervor, dass Faktoren aus den drei Bereichen „Lernbedingungen“, „Soziale Interaktion“ und „Fähigkeiten in den Exekutiven Funktionen“ eine schützende oder risikofördernde Wirkung haben können. Als präventive Massnahmen wurden in den empirischen Arbeiten vor allem die Weiterbildung von Lehrpersonen sowie der Einsatz von Gruppeninterventionsprogrammen thematisiert. Eine Reihe von pädagogischen Handlungsmöglichkeiten wurde genannt. Auf Grundlage der Ergebnisse dieser strukturierenden Inhaltsanalyse werden mögliche Massnahmen für die Praxis abgeleitet und weitere Forschungsdesiderate aufgezeigt.

description: This paper presents high-order integral equation methods for evaluation of electromagnetic wave scattering by dielectric bumps and dielectric cavities on perfectly conducting or dielectric half-planes. In detail, the algorithms introduced in this paper apply to eight classical scattering problems, namely: scattering by a dielectric bump on a perfectly conducting or a dielectric half-plane, and scattering by a filled, overfilled or void dielectric cavity on a perfectly conducting or a dielectric half-plane. In all cases field representations based on single-layer potentials for appropriately chosen Green functions are used. The numerical far fields and near fields exhibit excellent convergence as discretizations are refined--even at and around points where singular fields and infinite currents exist.

description: In stacks of transition metal dichalcogenide monolayers with arbitrary twisting angles, we explore a new class of bright excitons arising from the pronounced Förster coupling, whose dimensionality is tuned by its in-plane momentum. The low energy sector at small momenta is two-dimensional, featuring a Mexican Hat dispersion, while the high energy sector at larger momenta becomes three-dimensional (3D) with sizable group velocity both in-plane and out-of-plane. By choices of the spacer thickness, interface exciton mode strongly localized at designated layers can emerge out of the cross-dimensional bulk dispersion for a topological origin. Step-edges in spacers can be exploited for engineering lateral interfaces to enable interlayer communication of the topological interface exciton. Combined with the polarization selection rule inherited from the monolayer building block, these exotic exciton properties open up new opportunities for multilayer design towards 3D integration of valley exciton optoelectronics.

description: We consider a class of one dimensional Vector Nonlocal Non-linear Schrödinger Equation (VNNLSE) in an external complex potential with time-modulated Balanced Loss-Gain(BLG) and Linear Coupling(LC) among the components of Schrödinger fields, and space-time dependent nonlinear strength. The system admits Lagrangian and Hamiltonian formulations under certain conditions. It is shown that various dynamical variables like total power, $\cal{PT}$-symmetric Hamiltonian, width of the wave-packet and its speed of growth, etc. are real-valued despite the Hamiltonian density being complex-valued. We study the exact solvability of the generic VNNLSE with or without a Hamiltonian formulation. In the first part, we study time-evolution of moments which are analogous to space-integrals of Stokes variables and find condition for existence of solutions which are bounded in time. In the second part, we use a non-unitary transformation followed by a coordinate transformation to map the VNNLSE to various solvable equations. The cordinate transformation is not required at all for the limiting case when non-unitary transformation reduces to pseudo-unitary transformation. The exact solutions are bounded in time for the same condition which is obtained through the study of time-evolution of moments. Various exact solutions of the VNNLSE are presented.

description: The relevance of the present study devoted to the creation of modern information measuring systems with sensors based on diffraction gratings is shown. Information on the acousto-optic effect and acousto-optic materials is presented. A comparative assessment of the characteristics and possible applications of instruments and systems based on different physical effects and phenomena was carried out on foreign and domestic patent and technical literature. Based on the analysis of the literature, the task was set and the choice of effective ways of achieving the goal of the present work was accomplished. Perspective information and measuring systems with sensors based on diffraction gratings, as well as inadequate attention to design issues, have been established. The need for research in this field has been formulated.
Conserved quantities in STEGR and applications

description: We derive conservation laws in Symmetric Teleparallel Equivalent of General Relativity (STEGR) with direct application of Noether's theorem. This approach allows us to construct covariant conserved currents, corresponding superpotentials and invariant charges. A necessary component of our constructions is the concept of "turning off" gravity, introduced in the framework of STEGR to define the flat and torsionless connection. By calculating currents, one can obtain local characteristics of gravitational field like energy density. Surface integration of superpotentials gives charges which correspond to global quantities of the system like mass, momentum, etc. To test our results for the obtained currents and superpotentials, we calculate the energy density measured by freely falling observer in the simple solutions (Friedman universe, Schwartzchild black hole) and total mass of the Schwartzchild black hole. We find ambiguities in obtaining the connection, which explicitly affect the values of conserved quantities, and discuss possible solutions to this problem.

description: We propose a scheme to realize a frustrated Bose-Hubbard model with ultracold atoms in an optical lattice that comprises the frustrated spin-1/2 quantum XX model. Our approach is based on a square ladder of magnetic flux close to $π$ with one real and one synthetic spin dimension. Although this system does not have geometrical frustration, we show that at low energies it maps into an effective triangular ladder with staggered fluxes for specific values of the synthetic tunneling. We numerically investigate its rich phase diagram and show that it contains bond-ordered-wave and chiral superfluid phases. Our scheme gives access to minimal instances of frustrated magnets without the need for real geometrical frustration, in a setup of minimal experimental complexity.

Cavity-Enabled Self-Electro-Optic Bistability in Silicon Photonics
Creators: name: Majumdar, Arka

Publisher: name: arXiv
Year: 2014
Subjects: subject: Optics (physics.optics)

description: We propose a new type of bistable device for silicon photonics, using the self-electro-optic effect within an optical cavity. Since the bistability does not depend on the intrinsic optical nonlinearity of the material, but is instead engineered by means of an optoelectronic feedback, it appears at low optical powers. This bistable device satisfies all the basic criteria required in an optical switch to build a scalable digital optical computing system.

description: We consider a Newtonian system of many diatomicmolecules each of which consisting of two atoms of equal mass whichare separated by a fixed distance. The barycenters are allowed to movealong some fixed straight line. Moreover each molecule has an additionalrotational degree of freedom. The atoms of neighbouring moleculesinteract to each other by a generic pair potential. By means of thisexample we propose a new method for deriving macroscopic models from microscopic ones. The method is based on the definition of macroscopicobservables and the derivation of corresponding balance laws by interpolation smoothing/averaging and subsequent scaling of particle trajectories.
