description: In this paper we calculate the scale anomaly for a quantum field theoretic 2D-nonrelativistic Bose gas with contact interactions using Fujikawa's method, both in vacuum and in many-body systems. The use of path integrals for these problems is novel and motivated by a recently developed path-integral framework for addressing questions about scaling in these systems. A natural class of regulators is found that produces the correct value of the anomaly traditionally calculated via other methods, e.g., diagrammatically via the beta function.

description: We study topological black hole solutions of the simplest quadratic gravity action and we find that two classes are allowed. The first is asymptotically flat and mimics the Reissner-Nordström solution, while the second is asymptotically de Sitter or anti-de Sitter. In both classes, the geometry of the horizon can be spherical, toroidal or hyperbolic. We focus in particular on the thermodynamical properties of the asymptotically anti-de Sitter solutions and we compute the entropy and the internal energy with Euclidean methods. We find that the entropy is positive-definite for all horizon geometries and this allows to formulate a consistent generalized first law of black hole thermodynamics, which keeps in account the presence of two arbitrary parameters in the solution. The two-dimensional thermodynamical state space is fully characterized by the underlying scale invariance of the action and it has the structure of a projective space. We find a kind of duality between black holes and other objects with the same entropy in the state space. We briefly discuss the extension of our results to more general quadratic actions.

Fatal Sindbis Virus Infection of Neonatal Mice in the Absence of Encephalitis

description: A comparative pathogenesis study was performed in neonatal mice using a molecularly cloned laboratory variant of Sindbis strain AR339, designated TRSB, and a single-site attenuated mutant of TRSB derived by site-directed mutagenesis of the E2 glycoprotein from Ser to Arg at residue 114 (TRSBr114). TRSB caused 100% mortality with an average survival time of 3.0 +/- 0.7 days, whereas mice inoculated with TRSBr114 exhibited an attenuated disease course with 46% mortality and an extended average survival time of 7.5 +/- 3.4 days for those animals that died. Reduced virulence of TRSBr114 was characterized by delayed appearance of detectable virus, relative to TRSB, and by lower peak virus titers in both sera and brains of infected mice. TRSB infection induced very high peak serum titers of interferon alpha/beta (215,000 units/ml compared to 2100 units/ml for TRSBr114). In situ hybridization analysis demonstrated replication of TRSB in brain, but only minimal histopathological changes and no evidence of encephalitis were observed. However, extensive extraneural lesions and viral replication were found in skin, connective tissue, and muscle. Moreover, dramatic involution of the thymus and loss of hematopoietic tissues were observed in the absence of virus replication at these sites, suggesting the involvement of a systemic physiological stress response in TRSB infection. TRSBr114 infection did not cause thymic lesions. Otherwise, the attenuated mutant demonstrated a similar pattern of tissue and organ involvement, but lesions and positive in situ hybridization signal were much more limited in scope and intensity compared to TRSB. TRSBr114-infected mice developed myositis and encephalomyelitis approximately 6 days postinfection. Therefore, TRSB-infected animals may succumb to an early syndrome associated with the stress response, preventing their survival for a time sufficient for the development of encephalitis. Alternatively, a systemic stress response, as evidenced by thymic involution, may result in immunosuppression, thus contributing to the absence of encephalitis. In any event, the attenuating mutation in the E2 glycoprotein significantly altered the course of Sindbis-induced disease by limiting virus replication and associated damage early in infection. Mutant-infected animals survived beyond Day 4 and progressed to a classical encephalomyelitis from which about half recovered.

description: We investigate the generation of entanglement between two quantum emitters through the inverse-design engineering of their photonic environment. By means of a topology-optimization approach acting at the level of the electromagnetic Dyadic Green's function, we generate dielectric cloaks operating at different inter-emitter distances and incoherent pumping strengths. We show that the structures obtained maximize the dissipative coupling between the emitters under extremely different Purcell factor conditions, and yield steady-state concurrence values much larger than those attainable in free space. Finally, we benchmark our design strategy by proving that the entanglement enabled by our devices approaches the limit of maximum-entangled-mixed-states.

Natural Populations of Woodchuck Hepatitis Virus Contain Variant Precore and Core Sequences Including a Premature Stop Codon in the Epsilon Motif

description: We have determined a consensus sequence and the type and the frequency of spontaneous sequence variations in the woodchuck hepatitis virus (WHV) precore gene and the 5' region of the core gene in 101 serum samples from 53 naturally WHV-infected woodchucks by polymerase chain reaction sequencing. Twenty of the 53 woodchucks were found to have variant sequences. Ten patterns of variant sequences were identified in these 20 animals. WHV sequences from 4 woodchucks had 1 nucleotide change, 3 had 2 nucleotide changes and 3 had 3 nucleotide changes. The nucleotide changes were not randomly distributed, but were limited to only 8 sites. Four sites were in the epsilon motif of the precore gene and four were in the 5' region of the core gene. Sixteen of the 53 (30%) woodchucks had precore sequence variants. All altered sites were analogous to previously described mutations in hepatitis B virus. There was a nucleotide change at nucleotide 2016 in codon 29 of the precore region that produced a stop codon in 4 animals. This site is analogous to a common hepatitis B virus e antigen mutation. The sequence from the initial blood samples from 3 of 4 animals with this stop codon producing variant appeared to be the consensus sequence; however, in later samples the variant occurred as a mixed infection with the consensus sequence. The mixed infections were chronic and the proportion of the variant sequence was maintained or increased in the course of infection. In the fourth animal only the variant was found and it persisted for over 14 months of infection. WHV appears to be a valuable model for the study of the structure and function of the hepadnavirus precore region.

description: The function of the eye-like ocelloid in warnowiid dinoflagellates remains unknown because warnowiids are rare and uncultured, and scant molecular data exists for this group. While the ocelloid resembles the camera-type eyes found in animals, it is composed of organelles, with a highly modified plastid serving as the retinal body. By performing single-cell transcriptomics on cells isolated from the environment, we generate a comprehensive molecular dataset of warnowiids that includes all four known genera and one previously undescribed genus. We show that the heterotrophic members of this group have retained and express components of the ancestral photosynthetic mechanism, seemingly without photosystem II and RuBisCo. Our findings suggest that the ocelloid retinal body has repurposed the remaining photosystem to perform a function other than photosynthesis.

description: The Y2SiO5 (YSO) crystal is a dielectric material with biaxial anisotropy with known values of refractive index at optical frequencies. It is a well-known rare-earth (RE) host material for optical research and more recently has shown promising performance for quantum-engineered devices. In this paper, we report the first microwave characterization of the real permittivity tensor of a bulk YSO sample, as well as an investigation of the temperature dependence of the tensor components from 296 K down to 6 K. Estimated uncertainties were below 0.26%, limited by the precision of machining the cylindrical dielectric. Also, the electrical Q-factors of a few electromagnetic modes were recorded as a way to provide some information about the crystal losses over the temperature range. To solve the tensor components necessary for a biaxial crystal, we developed the multi-mode technique, which uses simultaneous measurement of low order Whispering Gallery Modes. Knowledge of the permittivity tensor offers important data, essential for the design of technologies involving YSO, such as microwave coupling to electron and hyperfine transitions in RE doped samples at low temperatures.

Preparations of Duck Hepatitis B Virions Contain Multiple DNA Polymerase Activities

description: The hepadnaviral DNA genome is synthesized by a viral-encoded reverse transcriptase, but the nature of this protein(s) in vivo remains obscure. We have previously described studies in which activity gel assays identified multiple DNA polymerase (DNAp) activities associated with highly purified duck hepatitis B virus (DHBV) core particles. We now report that virions isolated from viremic sera are associated with DNA-dependent DNAp activities which are nearly identical to major DNAp activities detected with highly purified DHBV core particles. These results suggest that the virion-associated polymerases are the same as those which are detected with core particles and are likely to represent DHBV pol gene products involved in replication of the genome.
title: Richard Strauss: The Origin, Dissemination and Reception of his Mozart Renaissance
Creators: name: Holden, Raymond
Publisher: name: Goldsmiths, University of London
Year: 1995

description: Richard Strauss holds an important place in the history of performance. Of the major musical figures active during the second half of the nineteenth and the first half of the twentieth centuries, his endeavours as a Mozartian are of particular importance. Strauss' special interest in the works of Mozart was seminal to both his performance and compositional aesthetics. As a result of this affinity, Strauss consciously set out to initiate a Mozart renaissance that embodied a precise set of principles and reforms. It was these principles and reforms, described as literalist, rather than those of artists such as Gustav Mahler, who edited Mozart's works both musically and dramatically, that found further expression in the readings of, amongst others, Otto Klemperer, George Szell, Sir John Pritchard and Wolfgang Sawallisch. It is the aim of this dissertation to investigate Strauss' activities as a Mozartian and to assess his influence on subsequent generations of Mozart conductors. Accordingly, the dissertation is divided into an Introduction, five chapters, a Conclusion and thirteen appendices. These consider both the nature and ramifications of Strauss' reforms and performance aesthetic. Within this framework, the breadth of his renaissance; his choice of edition, cuts and revisions; his use of tempo, as a means of structural delineation; his activities with respect to the recitative, and his realization of sonata form are discussed. Sources for this dissertation include: Strauss' own marked scores of Mozart's works, not previously considered; his recordings of Mozart; conversations and interviews between the present author and leading musical figures; unpublished extracts from his diaries, in the form of performance dates; articles written by Strauss on the performance of Classical music and, more particularly, that of Mozart; reviews from the period; recordings of later generations of Mozartians, some of which are not in the public domain, and, for the first time in print, the marked scores of Sir John Pritchard.

Structural Requirements for Initiation of Translation by Internal Ribosome Entry within Genome-Length Hepatitis C Virus RNA

description: Cap-independent translation of hepatitis C virus (HCV) RNA is mediated by an internal ribosomal entry segment (IRES) located within the 5' nontranslated RNA (5'NTR), but previous studies provide conflicting views of the viral sequences which are required for translation initiation. These discrepancies could have resulted from the inclusion of less than full-length 5'NTR in constructs studied for translation or destabilization of RNA secondary structure due to fusion of the 5'NTR to heterologous reporter sequences. In an effort to resolve this confusion, we constructed a series of mutations within the 5'NTR of a nearly full-length 9.5-kb HCV cDNA clone and examined the impact of these mutations on HCV translation in vitro in rabbit reticulocyte lysates and in transfected Huh-T7 cells. The inclusion of the entire open reading frame in HCV transcripts did not lead to an increase in IRES-directed translation of the capsid and E1 proteins, suggesting that the nonstructural proteins of HCV do not include a translational transactivator. However, in reticulocyte lysates programmed with full-length transcripts, there were multiple aberrent translation initiation sites resembling those identified in some picornaviruses. The deletion of nucleotides (nt) 28-69 of the 5'NTR (stem-loop IIa) sharply reduced capsid translation both in vitro and in vivo. A small deletion mutation involving nt 328-334, immediately upstream of the initiator AUG at nt 342, also resulted in a nearly complete inhibition of translation, as did the deletion of multiple intervening structural elements. An in-frame 12-nt insertion placed within the capsid-coding region 9 nt downstream of the initiator AUG strongly inhibited translation both in vitro and in vivo, while multiple silent mutations within the first 42 nt of the open reading frame also reduced translation in reticulocyte lysates. Thus, domains II and III of the 5'NTR are both essential to activity of the IRES, while conservation of sequence downstream of the initiator AUG is required for optimal IRES-directed translation.

description: We consider the most general single-spin-flip dynamics for the ferromagnetic Ising chain with nearest-neighbour influence and spin reversal symmetry. This dynamics is a two-parameter extension of Glauber dynamics corresponding respectively to non-linearity and irreversibility. The associated stationary state measure is given by the usual Boltzmann-Gibbs distribution for the ferromagnetic Hamiltonian of the chain. We study the properties of this dynamics both at infinite and at finite temperature, all over its parameter space, with particular emphasis on special lines and points.

description: A novel heterogeneous catalyst is prepared through functionalization of halloysite nanotube with 1H-1,2,3-triazole-5-methanol and subsequent immobilization of silver nanoparticles through bio-assisted approach using Arctiumplatylepis extract. The resulting catalyst, Ag@HNTs-T, was characterized by using SEM/EDX, BET, XRD, FTIR, ICP-AES, TGA, DTGA and elemental mapping analysis. Moreover, we computationally assessed metal-ligand interactions in Ag@HNTs-T complex model to interpret the immobilization behavior of silver nanoparticles on HNTs surface via quantum chemistry computations. The catalytic activity of the catalyst was studied for the synthesis of propargylamines via A3 and KA2 coupling reactions under ultrasonic irradiation. The results demonstrated that Ag@HNTs-T could efficiently promote these reactions to furnish the corresponding products in high yields and short reaction times. The study of the recyclability of the catalyst and Ag(0) leaching confirmed that the catalyst was recyclability up to four reaction runs with slight Ag(0) leaching.
A Noncanonical Poly(A) Signal, UAUAAA, and Flanking Elements in Epstein–Barr Virus DNA Polymerase mRNA Function in Cleavage and Polyadenylation Assays
Creators: name: Pagano, Joseph

description: Two forms of the Epstein-Barr virus DNA polymerase (pol) mRNA (3.7 and 5.1 kb) have been detected, neither of which contains a canonical poly(A) signal. The 5.1-kb pol mRNA, which contains a rare poly(A) signal, UAUAAA, studied only in transcripts of Hepadnaviridae and a plant pararetrovirus, was analyzed in cleavage and polyadenylation assays. Incubation of the pol transcript in cell extracts produced relatively low efficiency of cleavage (12 to 14%), which was improved by conversion of the poly(A) signal to AAUAAA. Deletion of the UAUAAA signal abolished cleavage and polyadenylation. An auxiliary element, UUUGUA, 3-8 nt upstream of the poly(A) signal and two downstream core elements, a GU-rich sequence 36-46 nt, and an AUUUGUGU sequence 47-53 nt downstream of the signal (8-19 nt and 20-28 nt downstream of cleavage site) facilitated processing of pol mRNA. Replacement of sequences near the cleavage/poly(A) site affected cleavage accuracy. Binding of the 64-kDa cleavage stimulatory factor to the U-rich as well as the GU-rich elements correlated with cleavage efficiency. Thus the UAUAAA hexanucleotide plus the other cis-acting elements are clearly functional in the native pol mRNA, but are relatively inefficient. Implications of the use of an anomalous poly(A) signal and its elements are discussed.

description: We analyse in detail the possibility of Bose-Einstein condensation of pions produced in heavy-ion collisions at the beam energy $\sqrt{s_{\rm NN}}$ = 2.76 TeV. Our approach is based on the chemical non-equilibrium thermal model of hadron production which has been generalised to include separately the contribution from the local zero-momentum state. In order to study both the hadronic multiplicities and the transverse-momentum spectra, we use the Cracow freeze-out model which parameterises the flow and space-time geometry of the system at freeze-out in a very economic way. Our analysis indicates that about 5% of all pions may form the Bose-Einstein condensate.

description: We report the discovery of a double-peaked Lyman-$α$ (Ly$α$) emitter (LAE) at $z=3.2177\pm0.0001$ in VLT/MUSE data. The galaxy is strongly lensed by the galaxy cluster RXC~J0018.5+1626 recently observed in the RELICS survey, and the double-peaked Ly$α$ emission is clearly detected in the two counter images in the MUSE field-of-view. We measure a relatively high Ly$α$ rest-frame equivalent width (EW) of $\mathrm{EW}_{\mathrm{Ly}α,0}=(63\pm2)\,\mathring{\mathrm{A}}$. Additional near-infrared (NIR) spectroscopy allows us to measure the H$β$, [OIII]$\lambda4959\,\mathring{\mathrm{A}}$ and [OIII]$\lambda5007\,\mathring{\mathrm{A}}$ emission lines, which show moderate rest-frame EWs of the order of a few $\sim10-100\,\mathring{\mathrm{A}}$, an [OIII]$\lambda5007\,\mathring{\mathrm{A}}$/H$β$ ratio of $4.8\pm0.7$, and a lower limit on the [OIII]/[OII] ratio of $>5.6$. The galaxy has very blue UV-continuum slopes of $β_{\mathrm{FUV}}=-2.23\pm0.06$ and $β_{\mathrm{NUV}}=-3.0\pm0.2$, and is magnified by factors $μ\sim7-10$ in each of the two images, thus enabling a view into a low-mass ($M_{\star}\simeq10^{7.5}\,\mathrm{M}_{\odot}$) high-redshift galaxy analog. Notably, the blue peak of the Ly$α$ profile is significantly stronger than the red peak, which suggests an inflow of matter and possibly very low HI column densities in its circumgalactic gas. Combined with the high lensing magnification and image multiplicity, these properties make this galaxy a prime candidate for follow-up observations to search for LyC emission and constrain the LyC photon escape fraction.

description: Coastal zones are critical ecosystems that provide important habitat for marine animals, fish, shellfish, birds, and many other species. However, there is a risk of mineral oil impacting in these areas due to human activities offshore. Shoreline classification is the first step to establishing response contingency plans in case of an oil spill. This study estimates the potential of using open-access, high-resolution Sentinel-1 and Sentinel-2 imagery for the mapping of shoreline types in support of oil spill preparedness and response activities. The two classification maps, depicting shoreline and coastal land cover, were produced using an advanced object-based Random Forest (RF) algorithm. Various features extracted from multi-source data, including spectral, texture, ratio, polarimetric features, and digital elevation model (DEM), were analyzed to identify the most valuable features for discrimination between different shoreline types. Multiple classification scenarios with the most useful features were then assessed and compared to find the best classification model. The developed algorithm achieved accuracies of 87.10% and 84.75% of coastal land cover and shoreline maps. These results demonstrated the high potential of using freely available Sentinel-1 and -2 satellite data for coastal mapping.

description: Motivated by the recently reported anomaly in W boson mass by the CDF collaboration with $7σ$ statistical significance, we consider a singlet-doublet (SD) Majorana fermion dark matter (DM) model where the required correction to W boson mass arises from radiative corrections induced by SD fermions. While a single generation of SD fermions, odd under an unbroken $Z_2$ symmetry, can not explain the W boson mass anomaly while being consistent with DM phenomenology, two generations of SD fermions can do so with the heavier generation playing the dominant role in W-mass correction and lighter generation playing the role in DM phenomenology. Additionally, such multiple generations of SD fermions can also generate light neutrino masses radiatively if a $Z_2$-odd singlet scalar is included.

description: Induction of a mucosal immune response is generally thought to require introduction of an immunogen directly onto the mucosal surface. It has been observed, however, that live, attenuated mutants of the alphavirus, Venezuelan equine encephalitis virus (VEE), induce protection from virulent challenge at the respiratory mucosa even after parenteral inoculation. In this report, we propose a mechanism by which subcutaneous immunization with a molecularly cloned, attenuated double mutant of VEE is able to stimulate the production of mucosal anti-VEE IgA. Our results showed that the immunizing virus spread to, and replicated within, lymphoid tissues throughout the mouse. Several tissues known to be inductive sites of the mucosal immune system were found to be positive for the presence of VEE RNA by 48 hr postimmunization. Moreover, this mucosal lymphotropism resulted in the production of virus-specific IgA antibody detectable in vaginal secretions of immunized mice.

description: Full exploitation of emittance exchange (EEX) requires aberration-free performance of a complex imaging system including active radio-frequency (RF) elements which can add temporal distortions. We investigate the performance of an EEX line where the exchange occurs between two dimensions with normalized emittances which differ by multiple orders of magnitude. The transverse emittance is exchanged into the longitudinal dimension using a double dog-leg emittance exchange setup with a five cell RF deflector cavity. Aberration correction is performed on the four most dominant aberrations. These include temporal aberrations that are corrected with higher order magnetic optical elements located where longitudinal and transverse emittance are coupled. We demonstrate aberration-free performance of an EEX line with emittances differing by four orders of magnitude, \textit{i.e.} an initial transverse emittance of 1~pm-rad is exchanged with a longitudinal emittance of 10~nm-rad.

description: The V3 domain plays a central role in the biology of the HIV-1 Env glycoprotein gp 120 as a dominant target for neutralizing antibodies for some HIV-1 isolates, and as a major determinant in the switch from the nonsyncytium-inducing (NSI) to the syncytium-inducing (SI) form of HIV-1 that is associated with accelerated disease progression. Basic amino acid substitutions are known to play an important role in the SI phenotype. We have used the presence of basic amino acid substitutions in V3 sequences to divide sequences in a large data base into SI-like and NSI-like. We found significant differences in features of sequence variability between these two groups of sequences. Of the thirty-six most frequent substitutions in V3, twenty appear disproportionately among either the SI-like sequences or the NSI-like sequences. The fourteen favored substitutions among the SI-like sequences account for 50% of the twofold increased variability seen in this group. In addition, we found a linked change within the CD4-binding domain of gp 120 downstream of V3. These differences are interpreted in the context of structure, function, and selective pressure. An understanding of these patterns of sequence variability offers the possibility of designing a degenerate SI-specific V3 immunogen to use as a therapeutic vaccine with the hope of slowing or preventing the appearance of SI variants.

description: Three main strategies are being pursued to search for non-gravitational dark matter signals: direct detection, indirect detection and collider searches. Interestingly, experiments have reached sensitivities in these three search strategies which may allow detection in the near future. In order to take full benefit of the wealth of experimental data, and in order to confirm a possible dark matter signal, it is necessary to specify the nature of the dark matter particle and of the mediator to the Standard Model. In this paper, we focus on a simplified model where the dark matter particle is a Majorana fermion that couples to a light Standard Model fermion via a Yukawa coupling with a scalar mediator. We review the observational signatures of this model and we discuss the complementarity among the various search strategies, with emphasis in the well motivated scenario where the dark matter particles are produced in the early Universe via thermal freeze-out.

description: The concept of centrality in high-energy nuclear collisions has recently become a subject of an active debate. In particular, the experimental methods to determine the centrality that have given reasonable results for many observables in high-energy lead-lead collisions at the LHC have led to surprising behaviour in the case of proton-lead collisions. In this letter, we discuss the possibility to calibrate the experimental determination of centrality by asymmetries caused by mutually different spatial distributions of protons and neutrons inside the nuclei --- a well-known phenomenon in nuclear physics known as the neutron-skin effect.

Illustrative deformation of volumetric objects and other graphical models
Creators: name: Correa, Carlos D.

description: The purpose of visualization is to gain understanding of 3D structures through images. Although many rendering techniques have been proposed for this purpose, the effective visualization remains a challenging task, due to occlusion, clutter, noise in the data, and acquisition pose. Recent solutions to this problem deal with transfer functions and other rendering techniques to enhance the visibility of certain parts of interest. At the core of these techniques is the assumption that the user's role is passive and that the data remains unchanged. In this thesis, we explore a more active approach to visualization, where a scientist can manipulate a dataset as if deforming a real model. We call this type of manipulation Illustrative Deformation. Our approach draws the name from the types of deformations that are often depicted in scientific illustration, which are used to enhance visibility of certain features while providing context, or to abstract the structure of an object or procedure. Inspired by medical and surgical illustration, our approach was designed to reproduce some of their key properties: illustrations often contains cuts and dissections, they allow feature-sensitive operations, which can be applied to a semantic component of the object without affecting other parts of the object, and they enable virtual operations, which do not necessarily conform to reality, but are useful for understanding the structure of complex objects.Our approach is based on a generalized notion of 3D displacement maps, which unifies the specification of continuous and discontinuous deformations on both volumes and surface-based objects. We show how displacements can describe a wide range of transformations, including cuts and peels, how they can be extended to include feature-sensitive operations, and how can they be implemented to obtain high quality interactive rendering on commodity hardware. We also show how our approach can be extended to the deformation of surface-based models without the need for remeshing.Through a number of examples and quantitative results, we demonstrate the generality, flexibility and scalability of our approach, and we explore its applications in medical illustration, surgical planning and simulation, and as a general tool for visualization and computer graphics.
