description: We investigate the existence of inhomogeneous Szekeres spacetimes in Einstein-æther theory. We show that inhomogeneous solutions which can be seen as extension of the Szekeres solutions existing in Einstein-æther gravity only for a specific relation between the dimensionless coefficients which defines the coupling between the æther filed with gravity. The two Szekeres classes of solutions are derived. Also a class of inhomogeneous FLRW-like spacetimes is allowed by the theory for arbitrary values of the dimensionless coefficients of the æther field. The stability of the solutions obtained is performed from where we find that the field equations evolve more variously in Einstein-æther than in General Relativity, where isotropic spacetimes and Kantowski-Sachs spacetimes are found to be attractors.

description: Wheeler's approach to finding exact solutions in Lovelock gravity has been predominantly applied to static spacetimes. This has led to a Birkhoff's theorem for arbitrary base manifolds in dimensions higher than four. In this work, we generalize the method and apply it to a stationary metric. Using this perspective, we present a Taub-NUT solution in eight-dimensional Lovelock gravity coupled to Maxwell fields. We use the first-order formalism to integrate the equations of motion in the torsion-free sector. The Maxwell field is presented explicitly with general integration constants, while the background metric is given implicitly in terms of a cubic algebraic equation for the metric function. We display precisely how the NUT parameter generalizes Wheeler polynomials in a highly nontrivial manner.

description: The square tight-binding model in a magnetic field leads to the almost-Mathieu operator which, for rational fields, reduces to a $q\times q$ matrix depending on the components $μ$, $ν$ of the wave vector in the magnetic Brillouinzone. We calculate the corresponding Green's function without explicit knowledge of eigenvalues and eigenfunctions and obtain analytical expressions for the diagonal and the first off-diagonal elements; the results which are consistent with the zero magnetic field case can be used to calculate several quantities of physical interest (e. g. the density of states over the entire spectrum, impurity levels in a magnetic field).

description: We explore the relation between the quantum and semiclassical instanton approximations for the reaction rate constant. From the quantum instanton expression, we analyze the contributions to the rate constant in terms of minimum-action paths and find that two such paths dominate the expression. For symmetric barriers, these two paths join together to describe the semiclassical instanton periodic orbit. However, for asymmetric barriers, one of the two paths takes an unphysically low energy and dominates the expression, leading to order-of-magnitude errors in the rate predictions. Nevertheless, semiclassical instanton theory remains accurate. We conclude that semiclassical instanton theory can only be obtained directly from the semiclassical limit of the quantum instanton for symmetric systems. We suggest a modification of the quantum instanton approach which avoids sampling the spurious path and thus has a stronger connection to semiclassical instanton theory, giving numerically accurate predictions even for very asymmetric systems in the low temperature limit.

description: There is increasing interest in many-body perturbation theory as a practical tool for the calculation of ground-state properties. As a consequence, unambiguous sum rules such as the conservation of particle number under the influence of the Coulomb interaction have acquired an importance that did not exist for calculations of excited-state properties. In this paper we obtain a rigorous, simple relation whose fulfilment guarantees particle-number conservation in a given diagrammatic self-energy approximation. Hedin's G_0W_0 approximation does not satisfy this relation and hence violates the particle-number sum rule. Very precise calculations for the homogeneous electron gas and a model inhomogeneous electron system allow the extent of the nonconservation to be estimated.

description: Introduction CD44 is a ubiquitous glycoprotein that carries theantigens of the Indian (IN) blood group system, Inaand Inb.INantigens are weakly expressed onIn(Lu)Lu(a-b-) cells. A novelCD44 antigen/antibody was previously reported in two unrelatedMoroccan females (referred to here as cases A and B) [Pooleetal. (2002)Transfusion Medicine,12(Suppl. 1), 32]. We report afurther example of this novel antigen, two examples of anotherhigh incidence CD44 antigen and the molecular basis of both. Case studies We studied an antibody to an unidentified high inci-dence antigen in the serum of a pregnant Moroccan female (caseC). Her red cells and serum were mutually compatible with theantibodies and red cells from A and B and presumed to be CD44related. Two further cases of suspected CD44 antibodies werefound in the sera of pregnant females (cases D and E). The redcells and antibodies of D and E were mutually compatible butincompatible with those of A, B and C. Results The antibodies in C, D and E reacted strongly with allpanel cells by indirect antiglobulin test but were negative afterpapain treatment.In(Lu)Lu(a-b-) cells were negative or weaklyreactive. The antibodies were positive in the monoclonal antibodyimmobilisation of erythrocyte antigens (MAIEA) assay usingmonoclonal antibodies to CD44. The red cells of C and E hadweaker expression of Inbthan control cells. Sequencing of exons1–5 of theCD44gene revealed a single mutation in exon 3 for C(255C > G resulting in H85Q in the protein). Her mother, babyand two sisters were heterozygous 255C > G and two sisters hadthe wild type 255C. Sequencing of exon 3 ofCD44showed Aand B to be homozygous for the same 255C > G mutation.Sequencing of exons 1–5 ofCD44revealed a single mutation inexon 5 for D and E (488C > A resulting in T163R in the pro-tein). The father and two siblings of E were also homozygous488C > A and their red cells were compatible with E’s antibody.E’s mother and two siblings were heterozygous for 488C > A. Conclusions We report two novel CD44 antigens, which we pro-pose to be IN3 and IN4 in the IN blood group system. Lack ofIN3 results from a 255C > G mutation predicting H85Q inCD44. A, B and C made anti-IN3 during pregnancy. Absence ofIN3 antigen has only been found in Moroccans. Lack of IN4results from a 488C > A mutation predicting T163R in CD44.D and E made anti-IN4 during pregnancy.

description: We report a correlated NanoSIMS-transmission electron microscopy study of the ungrouped carbonaceous chondrite Northwest Africa (NWA) 5958. We identified 10 presolar SiC grains, 2 likely presolar graphite grains, and 20 presolar silicate and/or oxide grains in NWA 5958. We suggest a slight modification of the commonly used classification system for presolar oxides and silicates that better reflects the grains' likely stellar origins. The matrix-normalized presolar SiC abundance in NWA 5958 is $18_{-10}^{+15}$ ppm (2$σ$), similar to that seen in many classes of unmetamorphosed chondrites. In contrast, the matrix-normalized abundance of presolar O-rich phases (silicates and oxides) is $30.9_{-13.1}^{+17.8}$ ppm (2$σ$), much lower than seen in interplanetary dust particles and the least altered CR, CO and ungrouped C chondrites, but close to that reported for CM chondrites. NanoSIMS mapping also revealed an unusual $^{13}$C-enriched ($δ^{13}$C$\sim$ 100--200 permil) carbonaceous rim surrounding a 1.4 $μ$m diameter phyllosilicate grain. TEM analysis of two presolar grains with a likely origin in asymptotic giant branch stars identified one as enstatite and one as Al-Mg spinel with minor Cr. The enstatite grain amorphized rapidly under the electron beam, suggesting partial hydration. TEM data of NWA 5958 matrix confirm that it has experienced aqueous alteration and support the suggestion of Jacquet et al. (2016) that this meteorite has affinities to CM2 chondrites.

It is experimentally shown that the magnetic aging diminishes to finally disappear for fields of moderate strength. The field needed to remove the observable aging behavior increases with decreasing temperature. The same qualitative behavior is observed in an amorphous metallic spin glass (Fe_{0.15}Ni_{0.85})_{75}P_{16}B_6Al_3.

description: The rising interest in single-channel multi-speaker speech separation sparked development of End-to-End (E2E) approaches to multi-speaker speech recognition. However, up until now, state-of-the-art neural network-based time domain source separation has not yet been combined with E2E speech recognition. We here demonstrate how to combine a separation module based on a Convolutional Time domain Audio Separation Network (Conv-TasNet) with an E2E speech recognizer and how to train such a model jointly by distributing it over multiple GPUs or by approximating truncated back-propagation for the convolutional front-end. To put this work into perspective and illustrate the complexity of the design space, we provide a compact overview of single-channel multi-speaker recognition systems. Our experiments show a word error rate of 11.0% on WSJ0-2mix and indicate that our joint time domain model can yield substantial improvements over cascade DNN-HMM and monolithic E2E frequency domain systems proposed so far.

description: Reactions with radioactive nuclear beams at relativistic energies have opened new doors to clarify the mechanisms of stellar evolution and cataclysmic events involving stars and during the big bang epoch. Numerous nuclear reactions of astrophysical interest cannot be assessed directly in laboratory experiments. Ironically, some of the information needed to describe such reactions, at extremely low energies (e.g., keVs), can only be studied on Earth by using relativistic collisions between heavy ions at GeV energies. In this contribution, we make a short review of experiments with relativistic radioactive beams and of the theoretical methods needed to understand the physics of stars, adding to the knowledge inferred from astronomical observations. We continue by introducing a more detailed description of how the use of relativistic radioactive beams can help to solve astrophysical puzzles and several successful experimental methods. State-of-the-art theories are discussed at some length with the purpose of helping us understand the experimental results reported. The review is not complete and we have focused most of it to traditional methods aiming at the determination of the equation of state of symmetric and asymmetric nuclear matter and the role of the symmetry energy. Whenever possible, under the limitations of our present understanding of experimental data and theory, we try to pinpoint the information still missing to further understand how stars evolve, explode, and how their internal structure might be.

description: An analysis of the Coulombic amplitude and its interference with the nuclear amplitude which is driven by the three-component Pomeron is presented. It is shown that different approaches towards the Coulomb phase evaluation give approximately uniform result at all energies and the difference is negligible at RHIC and LHC energies. We show that the use of the amplitude which was fitted to accomodate nucleon data only (in the region 0.01 < |t| < 14.5 (GeV^2)) combined with the Coulomb amplitude, reproduces the existing data in the Coulomb interference domain quite accurately without any adjustement of the parameters. As a consequence, we predict the differential cross section in the region of the Coulomb nucleon interference for both RHIC and LHC energies.

description: Interprofessional education (IPE) programs for pre-registration health science students are largely offered within one institution including different schools or faculties. Sometimes in small or regional institutions where there are limited student numbers or few professional training programs, or where larger institutions do not offer particular professional programs, it may be necessary to partner with other institutions to offer IPE. This study sought to explore teacher perspectives of forming inter-institutional partnerships to deliver IPE, in particular, to identify the elements that influence the formation of partnerships. An interpretive descriptive approach was used to thematically analyze data from three focus groups with teachers (n = 21) working in three different partnerships to deliver IPE to students in Wellington, New Zealand. Two main themes were identified which enabled the development of a model of partnership, with a continuum of complexity depending on whether institutions were on the same page and whether the partnership formed to join an existing IPE program or to create a new IPE program. Forming inter-institution partnerships is a pragmatic solution to providing IPE with benefits to all taking part. Our work showed that time, effort, working with complexity, and ability to stay on the same page are necessary elements for building successful partnerships and all need to be taken into account when planning inter-institution partnerships.
Search for direct stau production in events with two hadronic $τ$-leptons in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector

description: A search for the direct production of the supersymmetric partners of $τ$-leptons (staus) in final states with two hadronically decaying $τ$-leptons is presented. The analysis uses a dataset of $pp$ collisions corresponding to an integrated luminosity of $139$ fb$^{-1}$, recorded with the ATLAS detector at the Large Hadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected Standard Model background is observed. Limits are derived in scenarios of direct production of stau pairs with each stau decaying into the stable lightest neutralino and one $τ$-lepton in simplified models where the two stau mass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidence level for a massless lightest neutralino.

description: Causality imposes strong restrictions on the type of operators that may be observables in relativistic quantum theories. In fact, causal violations arise when computing conditional probabilities for certain partial causally connected measurements using the standard non covariant procedure. Here we introduce another way of computing conditional probabilities, based on an intrinsic covariant relational order of the events, which differs from the standard one when these type of measurements are included. This alternative procedure is compatible with a wider and very natural class of operators without breaking causality. If some of these measurements could be implemented in practice as predicted by our formalism, the non covariant, conventional approach should be abandoned. Furthermore, the description we promote here would imply a new physical effect where interference terms are suppressed as a consequence of the covariant order in the measurement process.

description: We study limits of infinite distance in the moduli space of 4d $\mathcal{N} = 2$ string compactifications, in which instanton effects dominate. We first consider trajectories in the hypermultiplet moduli space of type IIB Calabi-Yau compactifications. We observe a correspondence between towers of D-brane instantons and D-brane 4d strings, such that the lighter the string the more relevant the instanton effects are. The dominant instantons modify the classical trajectory such that the lightest D-brane string becomes tensionless even faster, while the other strings are prevented to go below the fundamental string tension. This lightest string is dual to a fundamental type IIB string and realises the Emergent String Conjecture. We also consider the vector multiplet moduli space of type I string theory on $K3 \times T^2$ , where quantum corrections can also become significant. Naively, we only find trajectories that correspond to decompactification limits, in apparent contradiction with the picture obtained in some dual setup.

It is shown that the best processes for the determination of $N_c$ are the reactions $Kγ\to Kπ$ and $π^pmγ\toπ^\pmη$ as well as the decay $η\raπ^+π^-γ$. The measurement of the cross section $σ(π^-γ\raπ^-η)$ at the VES facility at the IHEP agrees with the value $N_c=3$.

description: In radio astronomy obtaining a high dynamic range in synthesis imaging of wide fields requires a correction for time and direction-dependent effects. Applying direction-dependent correction can be done by either partitioning the image in facets and applying a direction-independent correction per facet, or by including the correction in the gridding kernel (AW-projection). An advantage of AW-projection over faceting is that the effectively applied beam is a sinc interpolation of the sampled beam, where the correction applied in the faceting approach is a discontinuous piece wise constant beam. However, AW-projection quickly becomes prohibitively expensive when the corrections vary over short time scales. This occurs for example when ionospheric effects are included in the correction. The cost of the frequent recomputation of the oversampled convolution kernels then dominates the total cost of gridding. Image domain gridding is a new approach that avoids the costly step of computing oversampled convolution kernels. Instead low-resolution images are made directly for small groups of visibilities which are then transformed and added to the large $uv$ grid. The computations have a simple, highly parallel structure that maps very well onto massively parallel hardware such as graphical processing units (GPUs). Despite being more expensive in pure computation count, the throughput is comparable to classical W-projection. The accuracy is close to classical gridding with a continuous convolution kernel. Compared to gridding methods that use a sampled convolution function, the new method is more accurate. Hence the new method is at least as fast and accurate as classical W-projection, while allowing for the correction for quickly varying direction-dependent effects.

description: We report three patients who developed haemolysis following rifampicin treatment. Initially, autoimmune haemolytic anaemia (AIHA) of the warm type and/or an acute haemolytic transfusion reaction (AHTR) was suggested. The direct antiglobulin tests (DAT) were strongly positive for IgG and C3d, and tests for rifampicin-dependent antibodies were positive in all three cases, featuring C-specificity in one case. The outcome was fatal in two out of the three cases, presumably due to belated diagnosis. This shows that rifampicin may stimulate the production of autoantibodies (aab) and/or drug-dependent antibodies (ddab), and that the resulting haemolytic syndrome bears similarities with AIHA and AHTR.

description: We show that the stochastic interpretation of Tsallis' thermostatistics given recently by Beck [Phys. Rev. Lett {\bf 87}, 180601 (2001)] leads naturally to a multi-parameter generalization. The resulting class of distributions is able to fit experimental results which cannot be reproduced within the Boltzmann's or Tsallis' formalism.

description: Understanding the origin of the magnetic fields in white dwarfs (WDs) has been a puzzle for decades. A scenario that has gained considerable attention in the past years assumes that such magnetic fields are generated through a dynamo process during common-envelope evolution. We performed binary population models using an up-to-date version of the BSE code to confront the predictions of this model with observational results. We found that this hypothesis can only explain the observed distribution of WD magnetic fields in polars and pre-polars and the low-temperature WDs in pre-polars if it is re-scaled to fit the observational data. Furthermore, in its present version, the model fails to explain the absence of young close detached WD+M-dwarf binaries harbouring hot magnetic WDs and predicts that the overwhelming majority of WDs in close binaries should be strongly magnetic, which is also in serious conflict with the observations. We conclude that either the common-envelope dynamo scenario needs to be substantially revised or a different mechanism is responsible for the generation of strong WD magnetic fields in close binaries.

description: We study the Aharonov-Bohm effect in a coupled 2$\times$2 quantum dot array with two-terminals. A striking conductance dip arising from the Fano interference is found as the energy levels of the intermediate dots are mismatched, which is lifted in the presence of a magnetic flux. A novel five peak structure is observed in the conductance for large mismatch. The Aharonov-Bohm evolution of the linear conductance strongly depends on the configuration of dot levels and interdot and dot-lead coupling strengths. In addition, the magnetic flux and asymmetry between dot-lead couplings can induce the splitting and combination of the conductance peak(s).

description: Introduction The Lutheran (LU) blood group system consists of 19 antigens numbered 1–21 (LU10, LU15 designated obsolete). There are four pairs of allelic and polymorphic antigens; Lua/Lub(LU1/LU2), LU6/LU9, LU8/LU14 and Aua/Aub(LU18/LU19). The remaining 11 are all antigens of high frequency. For the majority of Lutheran antigens the molecular bases have been determined and their expression is nearly always associated with a single amino acid change in the Lu-glycoprotein. Lutheran antigens are carried on two red cell membrane glycoproteins, Lu-glycoprotein and epithelial cancer antigen. The two isoforms are encoded by a single gene LU located on chromosome 19q13.2 and organised into 15 exons. Case Study and Methods We investigated a case of a prenatal patient with no known history of transfusion or previous pregnancies, whose serum contained an antibody giving positive reactions with all donor cells tested. Serological tests were performed by standard agglutination techniques. Genomic DNA was isolated from whole blood of the patient, all the exons of the LU gene were amplified by PCR and directly sequenced. Results Serological tests confirmed the presence of a Lutheran antibody in the patient's serum. All tested cells were incompatible with the patient's serum, except several examples of Lu(a-b-) cells of both the dominant and recessive phenotype. Her red cells were tested with antibodies to high frequency Lutheran antigens and failed to react with anti-Lu4. Sequencing of the LU gene revealed a novel homozygous mutation in exon 5 524G>T, causing an amino acid change Arg175Leu in the protein. This novel mutation was found in the same codon (523CGG) in LU exon 5 as the only other known example of LU:-4, where the change at the same nucleotide was 524G>A, leading to Arg175Gln substitution. Conclusion We report the second individual with the rare LU:-4 phenotype. We have confirmed the patient's serum contained an anti-Lu4 antibody. This phenotype results from a single point mutation in LU leading to an Arg175Leu amino acid change in the protein. This new point mutation occurred at the same nucleotide as the mutation in the only other known example of LU:-4. However, it caused a different amino acid substitution than in the original example, indicating a potential hot spot for mutations in LU.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: The LIGO observatories can potentially detect stochastic gravitational waves arising from phase transitions which happened in the early universe at temperatures around $T\sim 10^{8}$ GeV. This provides an extraordinary opportunity for discovering the phase transition associated with the breaking of the Peccei-Quinn symmetry, required in QCD axion models. Here we consider the simplest Peccei-Quinn models and study under which conditions a strong first-order phase transition can occur, analyzing its associated gravitational wave signal. To be detectable at LIGO, we show that some supercooling is needed, which can arise either in Coleman-Weinberg-type symmetry breaking or in strongly-coupled models. We also investigate phase transitions that interestingly proceed by first breaking the electroweak symmetry at large scales before tunneling to the Peccei-Quinn breaking vacuum. In this case, the associated gravitational wave signal is more likely to be probed at the proposed Einstein Telescope.

description: The differential diagnosis of anemia must consider immune hemolytic anemias as a frequent cause. Whereas detection of anti-red blood cell (RBC) alloantibodies frequently induced by immunogenic stimuli (transfusion, pregnancy) is performed by routine serology, diagnosing autoimmune hemolytic anemias or drug-induced hemolytic anemias remains a challenge, usually requiring close collaboration of a number of disciplines. Positive direct antiglobulin test (Coombs’ test) represents a central criterion in diagnosing immune hemolytic anemias, leading to further detailed analyses. The most-severe type of immune-mediated hemolysis is acute intravascular hemolysis after ABO incompatible RBC transfusion. This review highlights underlying biochemical aspects, immunohematological diagnostics, and the clinical relevance of RBC allo- and autoantibodies, including paroxysmal nocturnal hemoglobinemia and drug-induced hemolysis. Finally, current and partly experimental therapeutic strategies of immune hemolytic anemias are summarized.
