description: We study a class of loop-quantum-gravity states characterized by (ultra-local) thermal correlations that reproduce some features of the ultraviolet structure of the perturbative quantum field theory vacuum. In particular, they satisfy an analog of the Bisognano-Wichmann theorem. These states are peaked on the intrinsic geometry and admit a semiclassical interpretation. We study how the correlations extend on the spin-network beyond the ultra local limit.

description: Methods.There are no experimental data about the background experienced by microcalorimeters in the L2 orbit, and thus the particle background levels were calculated by means of Monte Carlo simulations: we considered the original design configuration and an improved configuration aimed to reduce the unrejected background, and tested them in the L2 orbit and in the low Earth orbit, comparing the results with experimental data reported by other X-ray instruments.To show the results obtainable with the improved configuration we simulated the observation of a faint, high-redshift, point source (F[0.5-10 keV]~6.4E-16 erg cm-2 s-1, z=3.7), and of a hot galaxy cluster at R200 (Sb[0.5-2 keV]=8.61E-16 erg cm-2 s-1 arcmin-2,T=6.6 keV). Results.First we confirm that implementing an active cryogenic anticoincidence reduces the particle background by an order of magnitude and brings it close to the required level.The implementation and test of several design solutions can reduce the particle background level by a further factor of 6 with respect to the original configuration.The best background level achievable in the L2 orbit with the implementation of ad-hoc passive shielding for secondary particles is similar to that measured in the more favorable LEO environment without the passive shielding, allowing us to exploit the advantages of the L2 orbit.We define a reference model for the diffuse background and collect all the available information on its variation with epoch and pointing direction.With this background level the ATHENA mission with the X-IFU instrument is able to detect ~4100 new obscured AGNs with F>6.4E-16 erg cm-2 s-1 during three years, to characterize cluster of galaxies with Sb(0.5-2 keV)>9.4E-16 erg cm-2 s-1 sr-1 on timescales of 50 ks (500 ks) with errors <40% (<12%) on metallicity,<16% (4.8%) on temperature,2.6% (0.72%) on the gas density, and several single-element abundances.

description: We show that asymptotically locally Lifshitz space-times are holographically dual to field theories that exhibit Schroedinger invariance. This involves a complete identification of the sources, which describe torsional Newton-Cartan geometry on the boundary and transform under the Schroedinger algebra. We furthermore identify the dual vevs from which we define and construct the boundary energy-momentum tensor and mass current and show that these obey Ward identities that are organized by the Schroedinger algebra. We also point out that even though the energy flux has scaling dimension larger than z+2, it can be expressed in terms of computable vev/source pairs.

Big-Bang Nucleosynthesis and Gamma-Ray Constraints on Cosmic Strings with a large Higgs condensate

description: We consider constraints on cosmic strings from their emission of Higgs particles, in the case that the strings have a Higgs condensate with amplitude of order the string mass scale, assuming that a fraction of the energy of condensate can be turned into radiation near cusps. The injection of energy by the decaying Higgs particles affects the light element abundances predicted by standard Big-Bang Nucleosynthesis (BBN), and also contributes to the Diffuse Gamma-Ray Background (DGRB) in the universe today. We examine the two main string scenarios (Nambu-Goto and field theory), and find that the primordial Helium abundance strongly constrains the string tension and the efficiency of the emission process in the NG scenario, while the strongest BBN constraint in the FT scenario comes from the Deuterium abundance. The Fermi-LAT measurement of the DGRB constrains the field theory scenario even more strongly than previously estimated from EGRET data, requiring that the product of the string tension μ and Newton's constant G is bounded by Gμ < 2.7x10^{-11}β_{ft}^{-2}, where β_{ft}^2 is the fraction of the strings' energy going into Higgs particles.

Supernovae Driven Turbulence In The Interstellar Medium

Publisher: name: arXiv
Year: 2014
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: I model the multi-phase interstellar medium (ISM) randomly heated and shocked by supernovae, with gravity, differential rotation and other parameters we understand to be typical of the solar neighbourhood. The simulations are 3D extending horizontally 1 x 1 kpc squared and vertically 2 kpc, symmetric about the galactic mid-plane. They routinely span gas number densities 1/10000 to 100 per cubic cm, temperatures 100 to 100 MK, speeds up to 10000 km/s and Mach number up to 25. Radiative cooling is applied from two widely adopted parameterizations, and compared directly to assess the sensitivity of the results to cooling. There is strong evidence to describe the ISM as comprising well defined cold, warm and hot regions, which are statistically close to thermal and total pressure equilibrium. This result is not sensitive to the choice of parameters considered here. The distribution of the gas density within each can be robustly modelled as lognormal. Appropriate distinction is required between the properties of the gases in the supernova active mid-plane and the more homogeneous phases outside this region. The connection between the fractional volume of a phase and its various proxies is clarified. An exact relation is then derived between the fractional volume and the filling factors defined in terms of the volume and probabilistic averages. These results are discussed in both observational and computational contexts. The correlation scale of the random flows is calculated from the velocity autocorrelation function; it is of order 100 pc and tends to grow with distance from the mid-plane. The origin and structure of the magnetic fields in the ISM is also investigated in non-ideal MHD simulations. A seed magnetic field, with volume average of roughly 4 nG, grows exponentially to reach a statistically steady state within 1.6 Gyr.

However, evidence that this B-cell immunity is accompanied by T-cell responses to the cognate antigens is scarce. Here, we examined T- and B-cell responses to DBY antigen in a male patient who received hematopoietic stem cells from a human leukocyte antigen-identical female sibling.

Correlated Quantum Dynamics of a Single Atom Collisionally Coupled to an Ultracold Finite Bosonic Ensemble

description: We explore the correlated quantum dynamics of a single atom, regarded as an open system, with a spatio-temporally localized coupling to a finite bosonic environment. The single atom, initially prepared in a coherent state of low energy, oscillates in a one-dimensional harmonic trap and thereby periodically penetrates an interacting ensemble of $N_A$ bosons, held in a displaced trap. We show that the inter-species energy transfer accelerates with increasing $N_A$ and becomes less complete at the same time. System-environment correlations prove to be significant except for times when the excess energy distribution among the subsystems is highly imbalanced. These correlations result in incoherent energy transfer processes, which accelerate the early energy donation of the single atom and stochastically favour certain energy transfer channels depending on the instantaneous direction of transfer. Concerning the subsystem states, the energy transfer is mediated by non-coherent states of the single atom and manifests itself in singlet and doublet excitations in the finite bosonic environment. These comprehensive insights into the non-equilibrium quantum dynamics of an open system are gained by ab-initio simulations of the total system with the recently developed Multi-Layer Multi-Configuration Time-Dependent Hartree Method for Bosons.

Understanding the aggregation mechanism of ligand coated gold nanoparticles in lipid bilayers
Creators: name: Ennis, Jahmal
Publisher: name: No Publisher Supplied

description: Gold nanoparticle aggregation is a phenomenon observed across many disciplines. We are particularly interested in the controlled aggregation of gold nanoparticles in lipid bilayers. While there has been much work done to understand the mechanism of penetration of gold nanoparticles and interactions of charged gold nanoparticle surface ligands with membranes, the mechanism of gold nanoparticle aggregation is not fully understood. A better understanding of the mechanism of gold nanoparticle aggregation can improve many fields including, but not limited to, targeted drug delivery. We use Coarse Grained Molecular Dynamics to study the mechanism of gold nanoparticle aggregation in various membrane compositions. Our results suggest that both membrane deformation and microscopic lipid deformation lead to aggregation, while ligand chain entropy acts as a balance to reduce aggregation and structure gold nanoparticle’s.

description: The integrability conditions for the existence of a conformal Killing-Yano tensor of arbitrary order are worked out in all dimensions and expressed in terms of the Weyl tensor. As a consequence, the integrability conditions for the existence of a Killing-Yano tensor are also obtained. By means of such conditions, it is shown that in certain Einstein spaces one can use a conformal Killing-Yano tensor of order p to generate a Killing-Yano tensor of order (p-1). Finally, it is proved that in maximally symmetric spaces the covariant derivative of a Killing-Yano tensor is a closed conformal Killing-Yano tensor and that every conformal Killing-Yano tensor is uniquely decomposed as the sum of a Killing-Yano tensor and a closed conformal Killing-Yano tensor.

Polyomavirus Nephropathy: Quantitative Urinary Polyomavirus-Haufen Testing Accurately Predicts the Degree of Intrarenal Viral Disease

description: BackgroundA qualitative highly predictive urinary test for polyomavirus nephropathy (PVN) is the PV-Haufen test. This article evaluates whether a quantitative PV-Haufen analysis, that is, the number of PV-Haufen shed per milliliter urine, predicts PVN disease grades and the severity of intrarenal PV replication.MethodsPolyomavirus-Haufen were counted in 40 urine samples from patients with biopsy-proven definitive PVN. The number of PV-Haufen was correlated with both histologic PVN disease grades 1 to 3 and the number of SV40-T–expressing cells as indicators of intrarenal PV replication in corresponding renal allograft biopsies (manual counts and automated morphometry). Findings from quantitative PV-Haufen analyses were compared to conventional laboratory test results, that is, BK viremia (quantitative polymerase chain reaction [PCR]) and BK viruria (quantitative PCR and decoy cell counts).ResultsPolyomavirus-Haufen counts showed excellent correlation (α0.77–0.86) with the severity of intrarenal PV replication and disease grades. In particular, low PV-Haufen numbers strongly correlated with early PVN grade 1 and minimal intrarenal expression of SV40-T antigen (P < 0.001). In comparison, BK viremia and viruria levels by PCR showed only modest correlations with histologic SV40-T expression (α0.40–0.49) and no significant correlation with disease grades or minimal intrarenal PV replication. No correlations were seen with urinary decoy cell counts. In contrast to conventional quantitative PCR assays or decoy cell counts, quantitative urinary PV-Haufen testing accurately reflects the severity of PV replication, tissue injury, and PVN disease grades.ConclusionsQuantitative PV-Haufen testing is a novel noninvasive approach to patient management for the diagnosis and prediction of PVN disease grades and monitoring of disease course during therapy.Quantitative testing of polyoma virus within shed renal tubule cells in the urine is superior to conventional BKV urinary or blood quantitation to define both the presence and degree of polyoma nephropathy.

description: Understanding the contextual factors associated with why adults walk is important for those interested in increasing walking as a mode of transportation and leisure. This paper investigates the relationships between neighborhood-level sociodemographic context, individual level sociodemographic characteristics and walking for leisure and transport. Data from two community-based studies of adults (n=550) were used to determine the association between the area-sociodemographic environment (ASDE), calculated from U.S. Census variables, and individual-level SES as potential correlates of walking behavior. Descriptive statistics, mean comparisons and Pearson’s correlations coefficients were used to assess bivariate relationships. Generalized estimating equations were used to model the relationship between ASDE, as quartiles, and walking behavior. Adjusted models suggest adults engage in more minutes of walking for transportation and less walking for leisure in the most disadvantaged compared to the least disadvantaged neighborhoods but adding individual level demographics and SES eliminated the significant results. However, when models were stratified for free or reduced cost lunch, of those with children who qualified for free or reduced lunch, those who lived in the wealthiest neighborhoods engaged in 10.7 minutes less of total walking per day compared to those living in the most challenged neighborhoods (p<0.001). Strategies to increase walking for transportation or leisure need to take account of individual level socioeconomic factors in addition to area-level measures.

description: We study non-relativistic field theory coupled to a torsional Newton-Cartan geometry both directly as well as holographically. The latter involves gravity on asymptotically locally Lifshitz space-times. We define an energy-momentum tensor and a mass current and study the relation between conserved currents and conformal Killing vectors for flat Newton-Cartan backgrounds. It is shown that flat NC space-time realizes two copies of the Lifshitz algebra that together form a Schroedinger algebra (without the central element). We show why the Schroedinger scalar model has both copies as symmetries and the Lifshitz scalar model only one. Finally we discuss the holographic dual of this phenomenon by showing that the bulk Lifshitz space-time realizes the same two copies of the Lifshitz algebra.

description: The evolutionarily conserved cullin family proteins can assemble as many as 400 distinct E3 ubiquitin ligase complexes that regulate diverse cellular pathways. CUL4, one of three founding cullins conserved from yeast to humans, uses a large β-propeller protein, DDB1, as a linker to interact with a subset of WD40 proteins that serve as substrate receptors, forming as many as 90 E3 complexes in mammals. Many CRL4 complexes are involved in chromatin regulation and are frequently hijacked by different viruses.

description: We demonstrate quantum bath engineering for preparation of any orbital state with controllable phase factor of a superconducting flux qubit assisted by a microwave coplanar waveguide resonator. We investigate the polarization efficiency of the arbitrary direction rotating on the Bloch sphere, and obtain an effective Rabi frequency by using the convergence condition of Markovian master equation. The processes of polarization can be implemented effectively in a dissipative environment created by resonator photon loss when the spectrum of the microwave resonator matches with the specially tailored Rabi and resonant frequencies of the drive. Our calculations indicate that state-preparation fidelities in excess of 99\% and the required time on the order of magnitude of microsecond are in principle possible for experimentally reasonable sample parameters. Furthermore, our proposal could be applied to other systems with spin-based qubits.

title: Vom Stadtrat zum Honoratiorenzirkel
Creators: name: Ekel, Marlene
Year: 2022

description: In Ägypten wurden um das Jahr 200 Stadträte (boulai) etabliert, wodurch auch hier wie im restlichen römischen Reich eine Kurialenschicht entstand, die für die munizipale Verwaltung verantwortlich war. Bereits ab dem 4. Jh. setzte ein langsamer Niedergang des Kurialenstandes ein. Die lokalen Eliten veränderten sich, sodass ihnen nicht mehr nur Kuriale angehörten, sondern weitere Gruppen, wie honorati und Großgrundbesitzer, die zusammenfassend als Notable bezeichnet werden. Diese neue Oberschicht wurde allmählich für die Verwaltung zuständig und die Kurialen traten in den Hintergrund. Ziel der vorliegenden Arbeit ist es, zu verfolgen wie lange Kuriale, bestimmte Ämter sowie die Räte noch belegt sind. Mithilfe papyrologischer Datenbanken wird eine Auflistung der spätesten Belege erstellt. In einem ersten Schritt werden die traditionellen munizipalen Ämter herangezogen, bevor auf die Begriffe boule, bouleutai und politeuomenoi eingegangen wird. Zuletzt werden die spätantiken Ämter untersucht. Dabei soll der Fokus auf den Kurialen bleiben. Im Laufe des 4. Jh. kam es zu wichtigen Veränderungen, als zunächst die traditionellen Ämter nicht mehr besetzt wurden. Gegen Ende des 4. Jh. treten politeuomenoi, Angehörige der Kurialenschicht und nicht des Rates selbst, auf und gewinnen an Bedeutung. Die weitreichendere Kurialenschicht und die neuen lokalen Eliten wurden für die städtische Verwaltung zuständig. Die boule war Mitte des 5. Jh. sicherlich noch tätig und bouleutai sind bis ins 7. Jh. belegt, der proedros zumindest bis zur Mitte des 6. Jh. Es gab also zu diesem Zeitpunkt zumindest noch eine Versammlung der bouleutai. Die meisten Ämter wurden zum letzten Mal im frühen 6. Jh. von Kurialen besetzt.
title: Erfolgsfaktoren für Onlineshops während der Covid-19 Pandemie
Creators: name: Schruf, Christoph
Year: 2022

description: In der vorliegenden Masterarbeit werden die Einflussfaktoren auf das Onlineshopping während der Covid-19 Pandemie untersucht. Dies wird anhand einer literarischen Aufarbeitung und eines darauf aufbauenden Fragebogens analysiert. Die Auswertung des Fragebogens erfolgte mittels deskriptiver Statistik sowie Korrelationsanalyse im Programm „IBM SPSS“. Die Datenanalyse ergab, dass von den neun in der Literatur abgeleitete Einflussfaktoren, welche sich positiv auf den Online-Einkauf auswirken, sechs auch während der Covid-19 Pandemie zutreffend waren. Diese sechs Faktoren beinhalten Product, Price, Personalization, Community, Security und Site Design. Für die verbleibenden drei Faktoren, Place, Promotion und Customer Service, konnte kein positiver Effekt auf den Online-Einkauf während der Covid-19 Pandemie nachgewiesen werden. Die Arbeit zielt nicht auf kausale Zusammenhänge ab, sondern baut auf statistisch signifikanten Korrelationen auf.

description: We describe presentations of braid groups of type ADE and show how these presentations are compatible with mutation of quivers, building on work of Barot and Marsh for Coxeter groups. In types A and D these presentations can be understood geometrically using triangulated surfaces. We then give a categorical interpretation of the presentations, with the new generators acting as spherical twists at simple modules on derived categories of Ginzburg dg-algebras of quivers with potential.

The Sec14 superfamily and mechanisms for crosstalk between lipid metabolism and lipid signaling

description: Lipid signaling pathways define central mechanisms of cellular regulation. Productive lipid signaling requires an orchestrated coupling0020between lipid metabolism, lipid organization, and the action of protein machines that execute appropriate downstream reactions. Using membrane trafficking control as primary context, we explore the idea that the Sec14-protein superfamily defines a set of modules engineered for the sensing of specific aspects of lipid metabolism and subsequent transduction of ‘sensing’ information to a phosphoinositide-driven ‘execution phase’. In this manner, the Sec14–superfamily connects diverse territories of the lipid metabolome with phosphoinositide signaling in a productive ‘crosstalk’ between these two systems. Mechanisms of crosstalk, where non-enzymatic proteins integrate metabolic cues with the action of interfacial enzymes, represent unappreciated regulatory themes in lipid signaling.

description: Многолетними данными массовых полевых опытов (более 450 опыто-лет наблюдений) выявлено, что прибавки урожайности корнеплодов сахарной свеклы от борных удобрений практически значимы ( до 25-60 ц/га), но они существенно варьируют в зависимости от почвенно-климатических условий ее возделываниия, агрохимических свойств почв, способов и доз используемого борного удобрения. Установлено, что на почвах дерново-подзолистых, серых лесных, черноземах оподзоленных приоритетным способом применения бора является основной ( в почву), а при возделывании сахарной свеклы на черноземах типичных и каштановых ( при орошении) – в приоритете находятся экономичные способы – обработка семян и некорневые подкормки; на черноземах выщелоченных – все способы практически равнозначны. Борные удобрения способствуют повышению сахаристости: при их основном внесении – на 0,7-1,4%, при некорневых подкормках – на 0,3-0,9% и при обработке семян бором – на 0,5-0,8%. Борные удобрения очень высоко окупаются прибавками урожая и способствуют повышению окупаемости традиционных (NPK) удобрений на 40-60%.
description: By long-term data of mass field experiments (more than 450 opyto-years of observations) it is revealed that increases of productivity of root crops of sugar beet from boric fertilizers are almost significant (to 25-60 c/hectare), but they significantly vary depending on soil and climatic conditions it a vozdelyvaniiya, agrochemical properties of soils, ways and doses of the used boric fertilizer. It is established that on soils cespitose and podsolic, gray forest, chernozems opodzolenny a priority method of application of a pine forest is the main (to the soil), and at cultivation of sugar beet on chernozems typical and chestnut (at irrigation) – in a priority there are economic ways – processing of seeds and not root top dressing; on chernozems lixivious – all ways are almost equivalent. Boric fertilizers promote increase in sugar content: at their main introduction – for 0,7-1,4%, at not root podkormka – for 0,3-0,9% and when processing seeds a pine forest – for 0,5-0,8%. Boric fertilizers very highly pay off increases of a harvest and promote increase in payback of traditional (NPK) fertilizers for 40-60%.
Regulation of intermediary metabolism by protein acetylation

description: Extensive studies during the past four decades have identified important roles for lysine acetylation in the regulation of nuclear transcription. Recent proteomic analyses on protein acetylation uncovered a large number of acetylated proteins in the cytoplasm and mitochondria, including most enzymes involved in intermediate metabolism. Acetylation regulates metabolic enzymes by multiple mechanisms, including via enzymatic activation or inhibition, and by influencing protein stability. Conversely, non-nuclear NAD+-dependent sirtuin deacetylases can regulate cellular and organismal metabolism, possibly through direct deacetylation of metabolic enzymes. Furthermore, acetylation of metabolic enzymes is highly conserved from prokaryotes to eukaryotes. Given the frequent occurrence of metabolic dysregulation in diabetes, obesity, and cancer, enzymes modulating acetylation could provide attractive targets for therapeutic intervention for these diseases.
Local thermal behaviour of a massive scalar field near a reflecting wall

description: The mean square fluctuation and the expectation value of the stress-energy-momentum tensor of a neutral massive scalar field at finite temperature are determined near an infinite plane Dirichlet wall, and also near an infinite plane Neumann wall. The flat background has an arbitrary number of dimensions and the field is arbitrarily coupled to the vanishing curvature. It is shown that, unlike vacuum contributions, thermal contributions are free from boundary divergences, and that the thermal behaviour of the scalar field near a Dirichlet wall differs considerably from that near a Neumann wall. Far from the wall the study reveals a local version of dimensional reduction, namely, corrections to familiar blackbody expressions are linear in the temperature, with the corresponding coefficients given only in terms of vacuum expectation values in a background with one less dimension. It is shown that such corrections are "classical" (i.e., not dependent on Planck's constant) only if the scalar field is massless. A natural conjecture that arises is that the "local dimensional reduction" is universal since it operates for massless and massive fields alike and regardless of the boundary conditions.

An Explanation of the WW Excess at the LHC by Jet-Veto Resummation

description: The WW production cross section measured at the LHC has been consistently exhibiting a mild excess beyond the SM prediction, in both ATLAS and CMS at both 7-TeV and 8-TeV runs. We provide an explanation of the excess in terms of resummation of large logarithms that arise from a jet-veto condition, i.e., the rejection of high-pT jets with pT > pT(veto) that is imposed in the experimental analyses to reduce backgrounds. Jet veto introduces a second mass scale pT(veto) to the problem in addition to the invariant mass of the WW pair. This gives rise to large logarithms of the ratio of the two scales that need to be resummed. Such resummation may not be properly accounted for by the Monte Carlo simulations used in the ATLAS and CMS studies. Those logarithms are also accompanied by large pi^2 terms when the standard, positive sign is chosen for the squared renormalization scale. We analytically resum the large logarithms including the pi^2 terms in the framework of soft collinear effective theory (SCET), and demonstrate that the SCET calculation not only reduces the scale uncertainties of the SM prediction significantly but also renders the theory prediction well compatible with the experiment. We find that resummation of the large logarithms and that of the pi^2 terms are both comparably important.

description: We report temperature-dependent neutron scattering measurements of the local dynamic structure factor in the quantum spin ladder (C$_{7}$H$_{10}$N)$_{2}$CuBr$_{4}$ in a magnetic field $H=9$~T, in its gapless quantum-critical phase. We show that the measured quantity has a scaling form consistent with expectations for a Tomonaga-Luttinger liquid with attraction. The measured Luttinger parameter $K\approx1.25$ and scaling function are in excellent agreement with density matrix renormalization group numerical calculations for the underlying spin Hamiltonian.

description: The security of public key validation protocols for web-based applications has recently attracted attention because of weaknesses in the certificate authority model, and consequent attacks. Recent proposals using public logs have succeeded in making certificate management more transparent and verifiable. However, those proposals involve a fixed set of authorities. This means an oligopoly is created. Another problem with current log-based system is their heavy reliance on trusted parties that monitor the logs. We propose a distributed transparent key infrastructure (DTKI), which greatly reduces the oligopoly of service providers and allows verification of the behaviour of trusted parties. In addition, this paper formalises the public log data structure and provides a formal analysis of the security that DTKI guarantees.
