description: Cosmic strings and primordial black holes (PBHs) commonly and naturally form in many scenarios describing the early universe. Here we show that if both cosmic strings and PBHs are present, their interaction leads to a range of interesting consequences. At the time of their formation, the PBHs get attached to the strings and influence their evolution, leading to the formation of black-hole-string networks and commonly to the suppression of loop production in a range of redshifts. Subsequently, reconnections within the network give rise to small nets made of several black holes and connecting strings. The number of black holes in the network as well as the stability of the nets depend on the topological properties of the strings. The nets oscillate and shrink exponentially due to the emission of gravitational waves. This leads to potentially observable string-driven mergers of PBHs. The strings can keep PBHs from galactic halos, making the current bounds on PBHs not generally applicable. Alternatively, heavy PBHs can drag low-tension strings into the centers of galaxies. The superconducting strings can appear as radio filaments pointing towards supermassive black holes.

description: Development of newer methods for the synthesis of Benzoxazoles has of greater interest due to their wide range of biological activities and pharmaceutical importance. We herein report a facile and general method for the synthesis of 2-substituted Benzoxazoles via copper catalyzed intramolecular C–O cross-coupling of 2-haloanilides. A combination of CuI (5 mol%), 2,2'-bipyridine (10 mol%), Cs2CO3 (2 equiv.) in DMF solvent with 4 Å molecular sieves at 140 °C, illustrated the scope for tuning the reactivity of 2-haloanilides toward the selective formation of a series of 2-alkyl benzoxazole derivatives in moderate to good yields. This is the first systematic study using CuI/2,2'-Bipyridine as the catalytic system for the synthesis of 2-substituted Benzoxazoles. The outcome of the reaction was found to be significantly influenced by the aromatic and amide substituents of 2-haloanilides.

description: We apply Renormalization Group techniques to the Real Time formulation of thermal field theory. Due to the separation between the $T=0$ and the $T\neq 0$ parts of the propagator in this formalism, one can derive exact evolution equations for the Green functions describing the effect of integrating out thermal fluctuations of increasing wavelengths, the initial conditions being the renormalized Green functions of the $T=0$ theory. As a first application, we study the phase transition for the real scalar theory, computing the order of the transition, the critical temperature, and critical exponents, in different approximations to the evolution equations for the scalar potential.

description: We investigate in the Hartree Fock approximation the temperature and filling dependence of the superconducting $π$-phase for the Penson-Kolb-Hubbard model. Due to the presence of the pair-hopping term, the phase survives for repulsive values of the on-site Coulomb interaction, exhibiting an interesting filling and temperature dependence. The structure of the self-consistent equations peculiar to the $π$-phase of the model allows to explicitly solve them for the chemical potential. The phase diagrams are shown and discussed in dimension 2 and 3. We also show that, when a next-nearest neighbours hopping term is included, the critical temperature of the superconducting region increases, and the corresponding range of filling values is shifted away from half-filling. Comparison with known exact results is also discussed.

description: Cold load pick-up (CLPU) has been a critical concern to utilities. Researchers and industry practitioners have underlined the impact of CLPU on distribution system design and service restoration. The recent large-scale deployment of smart meters has provided the industry with a huge amount of data that is highly granular, both temporally and spatially. In this paper, a data-driven framework is proposed for assessing CLPU demand of residential customers using smart meter data. The proposed framework consists of two interconnected layers: 1) At the feeder level, a nonlinear auto-regression model is applied to estimate the diversified demand during the system restoration and calculate the CLPU demand ratio. 2) At the customer level, Gaussian Mixture Models (GMM) and probabilistic reasoning are used to quantify the CLPU demand increase. The proposed methodology has been verified using real smart meter data and outage cases.

However, agreement with the experimental value of $α_s$ can be obtained if there are relatively large negative threshold corrections to $α_s$ coming from superheavy split multiplets. It is shown that such split multiplets can arise in SO(10) without fine-tuning of parameters.

description: A theoretical model of the reactions e+ e- --> K+ K- gamma and e+ e- --> K0 K0bar gamma has been derived. The strong interaction between kaons is taken into account using a general form of the K Kbar scattering amplitude. It is shown that some models formulated in the past are particular cases of the present approach. The formulae for the K Kbar effective mass dependence of the differential cross section as well as for the angular kaon and photon distributions and for the branching fractions of the phi(1020)--> K+ K- gamma and phi(1020)--> K0 K0bar gamma decays have been obtained. We present numerical results for the functions entering into transition amplitudes, K Kbar effective mass distributions, total cross sections, and branching fractions. Finally, the model is generalized to treat other reactions with two pseudoscalar mesons accompanying a photon in the final state.

 Hepatitis B is a viral illness that can harm the liver acutely or over time. Hepatitis B is a potentially fatal liver infection that can be brought on by the hepatitis B virus. This poses a serious threat to global health. It increases the risk of developing chronic infections in addition to the death risk from cirrhosis and liver cancer.(WHO,July16). Over 240 million people worldwide are chronically infected with the hepatitis B virus, with Asia and Africa having the highest infection rates
Cytoskeletal changes in macrophages in COPD
Creators: name: Anders, Katie Louise
Publisher: name: Imperial College London
Year: 2020

description: Chronic obstructive pulmonary disease (COPD) is a condition characterised by progressive lung function limitation. COPD is associated with airway inflammation and high numbers of inflammatory cells. Alveolar macrophages are the major phagocytic cell of the lung and control levels of pathogens through phagocytosis. Despite an increase in cell numbers in COPD subjects, there is evidence of bacterial colonisation possibly due to reduced phagocytosis. Reduced clearance of bacteria extends to fungal spores and apoptotic cells, suggesting defective phagocytosis of pathogens could contribute to colonisation, inflammation and disease progression. This thesis examines mechanisms underpinning defective bacterial phagocytosis. Monocyte-derived macrophages (MDM) from non-smokers, smokers and COPD subjects differentiated in GM-CSF were used to explore the role of the motor protein dynein in the context of defective phagocytosis in COPD. Defective bacterial phagocytosis of H. influenzae and S. pneumoniae was confirmed in COPD MDM, compared to non-smoker MDM and was associated with reduced trafficking of dynein. Inhibiting the movement of dynein in healthy cells also led to defective phagocytic uptake. To understand if these results were due to differences in cell signalling, leading to alterations in cytoskeletal rearrangements in COPD, the phosphorylation profile of MDM from COPD patients and controls in the absence or presence of H. influenzae was analysed. Analysis showed differential phosphorylation of several cytoskeletal associated proteins, including ezrin. Further analysis of ezrin suggested that reduced activation is linked to a reduction in phagocytosis in MDM, suggesting ezrin is important in this process. Changes to its expression or activity could contribute to defective phagocytosis, through its effect on microtubule instability, leading to reduced receptor recycling and early satiety. Cytoskeletal changes could be contributing to defective phagocytosis by COPD MDM. Investigations into defective phagocytosis aim to find an appropriate target for therapeutic modification, thereby restoring phagocytic capability, reducing bacterial load and diminishing inflammation.

description: El Rapa Nui Landscapes of Construction Project (LOC) ejecutó en enero/febrero de 2016 dos prospecciones superficiales intensivas (c. 500x500 m) en el extremo oriental de la península de Poike. Estas prospecciones fueron precedidas por una prospección fotográfica aérea y una prospección geofísica en la vecindad de Ahu Hati te Kohe y Viri Viri o Tumu, y de una prospección fotográfica aérea en Ahu Motu Toremo Hiva. Todas estas prospecciones previas fueron llevadas a efecto por el equipo de LOC en febrero de 2015. La primera de las prospecciones superficiales tuvo lugar tierra adentro de Ahu Hati te Kohe y Viri Viri o Tumu (P1), y la segunda en una zona situada a una distancia aproximada de 1.5 km al norte de la primera, tierra adentro de Kava Kava Makohe (P2). Además se visitaron dos yacimientos ya conocidos, aproximadamente 1 km al sudoeste de P1 (P3 and P4). El objetivo de estas cuatro prospecciones era caracterizar los restos arqueológicos en las áreas definidas e identificar yacimientos culturalmente significativos, caracterizar los riesgos erosivos, evaluar los daños sufridos y sus implicaciones interpretativas, establecer la inminencia y escala de los riesgos erosivos, y definir las prioridades de conservación y rescate. Estos objetivos pudieron cumplirse de forma satisfactoria. Se espera que esta información sirva para completar los datos recogidos en 1989 por Patricia Vargas, de la Universidad de Chile (1990), y más recientemente por Sonia Haoa, y que puedan así contribuir a la interpretación, la conservación y la planificación arqueológicas de la zona.

description: Neutron scattering measurements on the one-dimensional gapped S=1 antiferromagnet, CsNiCl3, have shown that the excitation corresponding to the Haldane mass gap Delta at low temperatures persists as a resonant feature to high temperatures. We find that the strong upward renormalisation of the gap excitation, by a factor of three between 5 and 70K, is more than enough to overcome its decreasing lifetime. We find that the gap lifetime is substantially shorter than that predicted by the scaling theory of Damle and Sachdev in its low temperature range of validity. The upward gap renormalisation agrees with the non-linear sigma model at low temperatures and even up to T of order 2Delta provided an upper mass cutoff is included.

Annual Purchases Survey, 2015-2017: Secure Access
Creators: name: Office For National Statistics
Publisher: name: UK Data Service
Year: 2019

description:
The primary aim of the Annual Purchases Survey is to provide a comprehensive picture of the goods and services used or transformed in the production process and running of UK businesses, otherwise referred to as intermediate consumption. This product-level information is used in supply and use tables (SUTs), which are an integral part of the measurement of gross domestic product (GDP). The Eurostat Manual of Supply Use and Input-Output Tables recommends that benchmarked supply and use tables are produced at least every five years based on updated source data.  A previous survey, entitled the Purchases Inquiry, was suspended in 2006 due to insufficient quality in the data and to reduce the ONS costs and burden on UK businesses (final reference period being 2004). However, given the survey provides important information on the products that UK businesses purchase, it was decided that it should be reintroduced. The new survey aims to strengthen the estimates of the intermediate consumption structure of the UK economy.

In 2016, Annual Purchases Survey questionnaires were sent by the ONS to approximately 31,000 businesses in the UK. In the UK, it is a compulsory survey that is administered under the statutory powers of the Statistics of Trade Act 1947 for Great Britain and under the Employment (Northern Ireland) Order 1988 for Northern Ireland.
Nonrestoration of spontaneously broken P, CP and PQ at high temperature

description: The possibility of P and CP violation at high temperature in models where these symmetries are spontaneously broken is investigated. It is found that in minimal models that include singlet fields, high T nonrestoration is possible for a wide range of parameters of the theory, in particular in models of CP violation with a CP-odd Higgs field. The same holds true for the invisible axion version of the Peccei-Quinn mechanism. This can provide both a way out for the domain wall problem in these theories and the CP violation required for baryogenesis. In the case of spontaneous P violation it turns out that high T nonrestoration requires going beyond the minimal model.The results are shown to hold true when next-to-leading order effects are considered.

description: A supersymmetric Yang-Mills system in (11,3) dimensions is constructed with the aid of two mutually orthogonal null vectors which naturally arise in a generalized spacetime superalgebra. An obstacle encountered in an attempt to extend this result to beyond 14 dimensions is described. A null reduction of the (11,3) model is shown to yield the known super Yang-Mills model in (10,2) dimensions. An (8,8) supersymmetric super Yang-Mills system in (3,3) dimensions is obtained by an ordinary dimensional reduction of the (11,3) model, and it is suggested there may exist a superbrane with (3,3) dimensional worldvolume propagating in (11,3) dimensions.

description: Von Neumann architecture based computers isolate/physically separate computation and storage units i.e. data is shuttled between computation unit (processor) and memory unit to realize logic/ arithmetic and storage functions. This to-and-fro movement of data leads to a fundamental limitation of modern computers, known as the memory wall. Logic in-Memory (LIM) approaches aim to address this bottleneck by computing inside the memory units and thereby eliminating the energy-intensive and time-consuming data movement. However, most LIM approaches reported in literature are not truly "simultaneous" as during LIM operation the bitcell can be used only as a Memory cell or only as a Logic cell. The bitcell is not capable of storing both the Memory/Logic outputs simultaneously. Here, we propose a novel 'Simultaneous Logic in-Memory' (SLIM) methodology that allows to implement both Memory and Logic operations simultaneously on the same bitcell in a non-destructive manner without losing the previously stored Memory state. Through extensive experiments we demonstrate the SLIM methodology using non-filamentary bilayer analog OxRAM devices with NMOS transistors (2T-1R bitcell). Detailed programming scheme, array level implementation and controller architecture are also proposed. Furthermore, to study the impact of introducing SLIM array in the memory hierarchy, a simple image processing application (edge detection) is also investigated. It has been estimated that by performing all computations inside the SLIM array, the total Energy Delay Product (EDP) reduces by ~ 40x in comparison to a modern-day computer. EDP saving owing to reduction in data transfer between CPU Memory is observed to be ~ 780x.

description: In the context of extended t-J models, with intersite Coulomb interactions of the form $-V\sum\limits_{< {i,j} >} {n_in_j}$, with n_i denoting the electron number operator at site i, nodal liquids are discussed. We use the spin-charge separation ansatz as applied to the nodes of a d-wave superconducting gap.Such a situation may be of relevance to the physics of high-temperature superconductivity. We point out the possibility of existence of certain points in the parameter space of the model characterized by dynamical supersymmetries between the spinon and holon degrees of freedom, which are quite different from the symmetries in conventional supersymmetric t-J models. Such symmetries pertain to the continuum effective field theory of the nodal liquid, and one's hope is that the ancestor lattice model may differ from the continuum theory only by renormalization-group irrelevant operators in the infrared. We give plausible arguments that nodal liquids at such supersymmetric points are characterized by superconductivity of Kosterlitz-Thouless type. The fact that quantum fluctuations around such points can be studied in a controlled way, probably makes such systems of special importance for an eventual non-perturbative understanding of the complex phase diagram of the associated high-temperature superconducting materials.

Dynamics of Totally Constrained Systems II. Quantum Theory

Publisher: name: arXiv
Year: 1995
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper a new formulation of quantum dynamics of totally constrained systems is developed, in which physical quantities representing time are included as observables. In this formulation the hamiltonian constraints are imposed on a relative probability amplitude functional $Ψ$ which determines the relative probability for each state to be observed, instead of on the state vectors as in the conventional Dirac quantization. This leads to a foliation of the state space by linear manifolds on each of which $Ψ$ is constant, and dynamics is described as linear mappings among acausal subspaces which are transversal to these linear manifolds. This is a quantum analogue of the classical statistical dynamics of totally constrained systems developed in the previous paper. It is shown that if the von Neumann algebra $\C$ generated by the constant of motion is of type I, $Ψ$ can be consistently normalizable on the acausal subspaces on which a factor subalgebra of $\C$ is represented irreducibly, and the mappings among these acausal subspaces are conformal. How the formulation works is illustrated by simple totally constrained systems with a single constraint such as the parametrized quantum mechanics, a relativistic free particle in Minkowski and curved spacetimes, and a simple minisuperspace model. It is pointed out that the inner product of the relative probability amplitudes induced from the original Hilbert space picks up a special decomposition of the wave functions to the positive and the negative frequency modes.

Increasing transparency on postdoctoral salaries and numbers

description: Background and rationale: In spite of being a large portion of the biomedical workforce, postdoctoral researchers are often the forgotten population in academia, with very little data existing on their salary, benefits, and career outcomes. Future of Research works for greater transparency on these issues, holding institutions accountable, and enabling early career researchers to advocate for evidence-based change in academia.

Methods: By contacting HR departments and postdoctoral offices, we monitored the compliance of institutions with a federal labor law mandating postdoctoral pay raises nationally. Subsequently, we submitted FOIA requests to U.S. public institutions to gather information on actual postdoctoral salary amounts and associated titles. We also helped to create an online platform (postdocsalaries.com) for self-reporting of individual postdoctoral salaries and benefits. In addition to these factors, in collaboration with Rescuing Biomedical Research, we examined biological sciences postdoc numbers within U.S. institutions on a yearly basis from 1980 to 2015 to shed light on how postdocs are counted nationally.

Results: Our institutional compliance monitoring affected decisions to raise postdoctoral salaries by comparing institutions side-by-side. The FOIA studies took this work further and showed large national discrepancies in pay levels based on gender and postdoc title, and a complex relationship between salaries and institutional federal funding levels. Finally, examining postdoc numbers showed institutional variability in reporting, resulting in fluctuations that mask larger trends in postdoc employment.

Significance: These studies demonstrate the lack of data availability and transparency around postdoctoral salaries and numbers, acting as a barrier to institutional change. We hope these studies shed light on the experiences of postdocs within institutions, and the need for reforms to improve institutional policy and tracking of postdocs nationwide.

description: The neutrino mean free path in neutron matter under a strong magnetic field is evaluated for the inelastic scattering reaction and studied as a function of the neutron matter density in the range $0.05 \leq ρ\leq 0.4$ fm$^{-3}$ for several temperatures up to 30 MeV and magnetic field strengths B=0 G, $10^{18}$ G and $2.5\times 10^{18}$ G. Polarized neutron matter is described within the non--relativistic Brueckner--Hartree--Fock (BHF) approach using the Argonne V18 nucleon-nucleon potential supplemented with the Urbana IX three-nucleon force. Explicit expressions of the cross section per unit volume for the scattering of a neutrino with a spin up or spin down neutron are derived from the Fermi Golden rule. Our results show that the mean free path depends strongly on the angle of the incoming neutrino, leading to an asymmetry in this quantity. This asymmetry depends on the magnetic field intensity and on the density, but it is rather independent of the temperature. For a density of $0.16$ fm$^{-3}$ at a temperature T$=30$MeV, the asymmetry in the mean free path is found to be of $\sim 15\%$ for B=$10^{18}$G and $\sim 38\%$ for B=$2.5 \times 10^{18}$G.

Entropy production for coarse-grained dynamics

description: Systems out of equilibrium exhibit a net production of entropy. We study the dynamics of a stochastic system represented by a Master Equation that can be modeled by a Fokker-Planck equation in a coarse-grained, mesoscopic description. We show that the corresponding coarse-grained entropy production contains information on microscopic currents that are not captured by the Fokker-Planck equation and thus cannot be deduced from it. We study a discrete-state and a continuous-state system, deriving in both the cases an analytical expression for the coarse-graining corrections to the entropy production. This result elucidates the limits in which there is no loss of information in passing from a Master Equation to a Fokker-Planck equation describing the same system. Our results are amenable of experimental verification, which could help to infer some information about the underlying microscopic processes.

description: The coronavirus disease 2019 (COVID-19) reportedly exacerbates cancer outcomes. However, how COVID-19 influences cancer prognosis and development remains poorly understood. Here, we investigated the effect of Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2), the etiological agent of COVID-19, on cellular cancer phenotypes the expression of cancer-related markers, and various proinflammatory cytokines. We infected prostate (22RV1) and colorectal (DLD-1) cancer cell lines, which express angiotensin-converting enzyme 2 (ACE2), with spike pseudovirus (sPV) and laboratory stocks of live SARS-CoV-2 viruses. After infection, we quantified changes in the cellular cancer phenotypes, the gene expression levels of some cancer markers, including Ki-67, BCL-2, VIM, MMP9, and VEGF, and proinflammatory cytokines. Phenotypic analysis was performed using MTT and wound healing assays, whereas gene expression analysis was carried out using real-time quantitative PCR (RT-qPCR). We show that SARS-CoV-2 infection impacts several key cellular pathways involved in cell growth, apoptosis, and migration, in prostate and colorectal cancer cells. Our results suggest that SARS-CoV-2 infection does influence various cancer cellular phenotypes and expression of molecular cancer markers and proinflammatory cytokines, albeit in a cell-type-specific manner. Our findings hint at the need for further studies and could have implications for evaluating the impact of other viruses on cancer progression.
Proving Heliocentrism and Measuring the Astronomical Unit in a Laboratory Astronomy Class via the Aberration of Starlight

description: The objective reality of the Earth's motion about the Sun was finally proven observationally by Bradley (1727) when he correctly explained the ~20'' annual, elliptical motions of stars as being due to aberration of starlight caused by the motion of the Earth. This effect can be detected today with ordinary astrophotographic equipment by measuring the coordinates of the center of star trails, which reveal the apparent position of the Celestial Poles, which vary due to the aberration of starlight, in addition to the effects of the nutation and precession of Earth's Poles. Despite my aspirations, I have not found the time to even begin the project of measuring the aberration. I nonetheless feel that it is a rich project in observational astronomy and fundamental physics, and a pleasingly didactic exercise appropriate for upper-division undergraduate and graduate astronomy and physics laboratory classes, whose complexity and length may be justified by the novelty of proving heliocentrism with nothing but a small telescope and camera. I therefore publish this Research Note to disseminate the idea in hopes that I might receive word in a few years of a triumphant astronomy class's proof of heliocentrism, along with their best estimates of the astronomical unit and precession.

description: We study the type IIB brane box configurations recently introduced by Hanany and Zaffaroni. We show that even at finite string coupling, one can construct smooth configurations of branes with fairly arbitrary gauge and flavor structure. Limiting our attention to the better understood case where NS-branes do not intersect over a four dimensional surface gives some restrictions on the theories, but still permits many examples, both anomalous and non-anomalous. We give several explicit examples of such configurations and discuss what constraints can be imposed on brane-box theories from bending considerations. We also discuss the relation between brane bending and beta-functions for brane-box configurations.

description: We present an exact diagonalisation study of bilayer quantum Hall systems at a filling factor of two in the spherical geometry. We find the high-Zeeman-coupling phase boundary of the broken symmetry canted antiferromagnet is given exactly by previous Hartree-Fock mean-field theories, but that the state's stability at weak Zeeman coupling has been qualitatively overestimated. In the absence of interlayer tunneling, degeneracies occur between total spin multiplets due to the Hamiltonian's invariance under independent spin-rotations in top and bottom two-dimensional electron layers.
