description: An approach aimed to extend the applicability range of non-relativistic microscopic calculations of electronuclear response functions is reviewed. In the quasielastic peak region the calculations agree with experiment at momentum transfers up to about 0.4 GeV/c while at higher momentum transfers, in the region about 0.4 - 1 GeV/c, a disagreement is seen. In view of this, to calculate the response functions a reference frame was introduced where dynamics relativistic corrections are small, and the results pertaining to it were transformed exactly to the laboratory reference frame. This proved to remove the major part of the disagreement with experiment. All leading order relativistic corrections to the transition charge operator and to the one--body part of the transition current operator were taken into account in the calculations. Furthermore, a particular model to determine the kinematics inputs of the non-relativistic calculations was suggested. This model provides the correct relativistic relationship between the reaction final-state energy and the momenta of the knocked-out nucleon and the residual system. The above mentioned choice of a reference frame in conjunction with this model has led to an even better agreement with experiment.

Understanding and Combating Robust Overfitting via Input Loss Landscape Analysis and Regularization

description: Adversarial training is widely used to improve the robustness of deep neural networks to adversarial attack. However, adversarial training is prone to overfitting, and the cause is far from clear. This work sheds light on the mechanisms underlying overfitting through analyzing the loss landscape w.r.t. the input. We find that robust overfitting results from standard training, specifically the minimization of the clean loss, and can be mitigated by regularization of the loss gradients. Moreover, we find that robust overfitting turns severer during adversarial training partially because the gradient regularization effect of adversarial training becomes weaker due to the increase in the loss landscapes curvature. To improve robust generalization, we propose a new regularizer to smooth the loss landscape by penalizing the weighted logits variation along the adversarial direction. Our method significantly mitigates robust overfitting and achieves the highest robustness and efficiency compared to similar previous methods.

description: Recent observations show that planet formation is already underway in young systems, when the protostar is still embedded into the molecular cloud and the accretion disc is massive. In such environments, the role of self gravity (SG) and gravitational instability (GI) is crucial in determining the dynamical evolution of the disc. In this work, we study the dynamical role of drag force in self-gravitating discs as a way to form planetesimals in early protoplanetary stages. We obtain the dispersion relation for density-wave perturbations on a fluid composed of two phases (gas and dust) interacting through the common gravitation field and the mutual drag force, and we find that the stability threshold is determined by three parameters: the local dust-to-gas density ratio, the dust relative temperature and the relevant Stokes number. In a region of parameters space, where young protoplanetary discs are likely to be found, the instability can be dust driven, occurring at small wavelengths. In this regime, the Jeans mass is much smaller than the one predicted by the standard gravitational instability model. This mechanism can be a viable way to form planetary cores in protostellar discs, since their predicted mass is about 10 Earth masses.

description: Orthostixinae Meyrick, 1892 Orthostixinae were not included in our study. Sihvonen et al. (2011) showed this subfamily as deeply embedded within Ennominae, but unfortunately it was not represented by the type genus of the subfamily. These results agree with Holloway (1996) who examined Orthostixis Hübner, (1823) and suggested the inclusion in Ennominae despite the full development of hindwing vein M2, the presence of a forewing areole and the very broad base of the tympanal ansa. We sampled the species Naxa textilis (Walker, 1856) and Orthostixis cribraria (Hübner, 1799), but only three and one marker were successfully sequenced for these samples, respectively. We included these species in the preliminary analyses but results were so unstable that we excluded them from the final analysis. Further research including fresh material and more genetic markers are needed to investigate the position of Orthostixinae conclusively.

description: Levy flights are random walks in which the probability distribution of the step sizes is fat-tailed. Levy spatial diffusion has been observed for a collection of ultra-cold Rb atoms and single Mg+ ions in an optical lattice. Using the semiclassical theory of Sisyphus cooling, we treat the problem as a coupled Levy walk, with correlations between the length and duration of the excursions. The problem is related to the area under Bessel excursions, overdamped Langevin motions that start and end at the origin, constrained to remain positive, in the presence of an external logarithmic potential. In the limit of a weak potential, the Airy distribution describing the areal distribution of the Brownian excursion is found. Three distinct phases of the dynamics are studied: normal diffusion, Levy diffusion and, below a certain critical depth of the optical potential, x~ t^{3/2} scaling. The focus of the paper is the analytical calculation of the joint probability density function from a newly developed theory of the area under the Bessel excursion. The latter describes the spatiotemporal correlations in the problem and is the microscopic input needed to characterize the spatial diffusion of the atomic cloud. A modified Montroll-Weiss (MW) equation for the density is obtained, which depends on the statistics of velocity excursions and meanders. The meander, a random walk in velocity space which starts at the origin and does not cross it, describes the last jump event in the sequence. In the anomalous phases, the statistics of meanders and excursions are essential for the calculation of the mean square displacement, showing that our correction to the MW equation is crucial, and points to the sensitivity of the transport on a single jump event. Our work provides relations between the statistics of velocity excursions and meanders and that of the diffusivity.

description: We study evolution of hydrogenated amorphous carbon (HAC) grains under harsh UV radiation in photo-dissociation regions (PDRs) near young massive stars. Our aim is to evaluate the impact of the HAC grains on formation of observed small hydrocarbons: C$_2$H, C$_2$H$_2$, C$_3$H$^+$, C$_3$H, C$_3$H$_2$, C$_4$H, in PDRs. We developed a microscopic model of the HAC grains based on available experimental results. The model includes processes of photo- and thermodesorption, accretion of hydrogen and carbon atoms and subsequent formation of carbonaceous mantle on dust surface. H$_2$, CH$_4$, C$_2$H$_2$, C$_2$H$_4$, C$_2$H$_6$, C$_3$H$_4$, C$_3$H$_6$, C$_3$H$_8$ are considered as the main fragments of the HAC photo-destruction. We simulated evolution of the HAC grains under the physical conditions of two PDRs, the Orion Bar and the Horsehead nebula. We estimated the production rates of the HAC fragments in gas phase chemical reactions and compared them with the production rates of fragments due to the HAC destruction. The latter rates may dominate under some conditions, namely, at A$_V$=0.1 in both PDRs. We coupled our model with the gas-grain chemical model MONACO and calculated abundances of observed small hydrocarbons. We conclude that the contribution of the HAC destruction fragments to chemistry is not enough to match the observed abundances, although it increases the abundances by several orders of magnitude in the Orion Bar at A$_V$=0.1. Additionally, we found that the process of carbonaceous mantle formation on dust surface can be an inhibitor for the formation of observed small hydrocarbons in PDRs.

description: Using the theory of wave turbulence for rapidly rotating incompressible fluids derived by Galtier (2003), we find the locality conditions that the solutions of the kinetic equation must satisfy. We show that the exact anisotropic Kolmogorov-Zakharov (KZ) spectrum satisfies these conditions, which justifies the existence of this constant (positive) energy flux solution. Although a direct cascade is predicted in the transverse ($\perp$) and parallel ($\parallel$) directions to the rotation axis, we show numerically that in the latter case some triadic interactions can have a negative contribution to the energy flux, while in the former case all interactions contribute to a positive flux. Neglecting the parallel energy flux, we estimate the Kolmogorov constant at $C_K \simeq 0.749$. These results provide theoretical support for recent numerical and experimental studies.

description: A bulk diluted magnetic semiconductor (Sr,K)(Zn,Mn)$_{2}$As$_{2}$ was synthesized with decoupled charge and spin doping. It has a hexagonal CaAl$_{2}$Si$_{2}$-type structure with the (Zn,Mn)$_{2}$As$_{2}$ layer forming a honeycomb-like network. Magnetization measurements show that the sample undergoes a ferromagnetic transition with a Curie temperature of 12 K and \revision{magnetic moment reaches about 1.5 $μ_{B}$/Mn under $μ_0H$ = 5 T and $T$ = 2 K}. Surprisingly, a colossal negative magnetoresistance, defined as $[ρ(H)-ρ(0)]/ρ(0)$, up to $-$38\% under a low field of $μ_0H$ = 0.1 T and to $-$99.8\% under $μ_0H$ = 5 T, was observed at $T$ = 2 K. The colossal magnetoresistance can be explained based on the Anderson localization theory.

description: Archaebalaenoptera Bisconti, 2007 Emended diagnosis of genus. Supraoccipital with rounded anterior border and strong transverse constriction; posterior apex of nuchal crest triangular in dorsal view and directed posteriorly; supraoccipital horizontally bent approximately at mid-length; zygomatic process of squamosal projecting anterolaterally and with sharply defined supramastoid crest; interorbital region of the frontal with transversely rounded sides; posterolateral corner of exoccipital protruding posteriorly. Discussion. Archaebalaenoptera differs from other balaenopterids in having a unique mix of morphological characters. In particular, while the transverse constriction of the supraoccipital is observed also in ‘Balaenoptera’ cortesii var. portisi, in Archaebalaenoptera the constriction is associated with a rounded anterior border of the supraoccipital; in ‘B.’ cortesii var. portisi the anterior border of the supraoccipital is narrow-to-pointed. The extended posteriorly protruding posterolateral corner of the exoccipital is also observed in Fragilicetus velponi but in that taxon, the supraoccipital is largely different being more squared at its anterior border and the being transverse constriction very reduced. In cross section, the round sides of the interorbital region of the frontal are typical of this genus and represent a marked difference with other balaenopterid genera where the sides of the interorbital region of the frontal are squared or concave.

description: Whenever a compound exhibits a spontaneous muSR oscillation, long-range magnetic ordering is usually inferred. Here we show that some caution is required. The coherence length needs not to be large for a spontaneous muon spin precession to be observed. Establishing the incommensurate nature of a magnetic structure, solely based on muSR measurements, may not be reliable. The absence of a spontaneous muon precession at low temperature does not mean that the system under investigation does not display long-range magnetic ordering. The relaxation measured in zero and longitudinal field in the quasi-static limit is usually analyzed in the framework of the strong-collision model, the static polarization function being taken to be the famous Kubo-Toyabe function. This might not be satisfactory if short-range correlation effects are strong. Here we propose a method based on the maximum entropy concept and reverse Monte Carlo technique which gives results consistent with those obtained in 2013 by analytical means for the considered example.

description: A low-energy fixed-point Hamiltonian is constructed for the s-wave odd-frequency pairing state with staggered ordering vector in the two-channel Kondo lattice. The effective model is justified because it reproduces low-energy behaviors of self energy obtained by the dynamical mean-field theory. The retardation effect is essential for the odd-frequency pairing, which comes from the hybridization process between conduction electrons and pseudofermions originating from localized spins at low energies. Using the effective Hamiltonian, the electromagnetic response functions are microscopically calculated. The present system shows the "weak" Meissner effect, where both paramagnetic and diamagnetic parts contribute to the Meissner kernel to give a small total diamagnetic response in the superconducting state. This feature is in contrast to the ordinary s-wave BCS pairing where only the diamagnetic kernel is finite in the ground state. The staggered nature of the odd-frequency order parameter plays an important role for the sign of the Meissner kernel.

Fast computations with the harmonic Poincaré-Steklov operators on nested refined meshes

Publisher: name: Weierstrass Institute

description: In this paper we develop asymptotically optimal algorithms for fast computations with the discrete harmonic Poincaré-Steklov operators in presence of nested mesh refinement. For both interior and exterior problems the matrix-vector multiplication for the finite element approximations to the Poincaré-Steklov operators is shown to have a complexity of the order O(Nreflog3N) where Nref is the number of degrees of freedom on the polygonal boundary under consideration and N = 2-p0 · Nref, p0 ≥ 1, is the dimension of a finest quasi-uniform level. The corresponding memory needs are estimated by O(Nreflog2N). The approach is based on the multilevel interface solver (as in the case of quasi-uniform meshes, see [20]) applied to the Schur complement reduction onto the nested refined interface associated with nonmatching decomposition of a polygon by rectangular substructures.

Müzeler somut ve somut olmayan kültürel değer ve mirası araştıran, toplayan, koruyan, yorumlayan ve sergileyen, toplumun hizmetinde olan ve kâr amacı gütmeyen kurumlardır. Müze eğitimi, insanı ve kendini zaman ve mekânda anlama çabasıdır. Kültürel mirası korumak; geçmişi, bugünü ve geleceği ilişkilendirmek; kültürel sanat eserlerini korumak, kendi ve farklı kültürlerini çok yönlü bir şekilde öğrenmek ve anlamak; nesiller arası anlayış ve empati geliştirmek, müzeleri yaşatmak müzelerin kurum niteliği kazanmasına yardımcı olmaktır.  Tarihi izleri ve kültürel değerlerimizi güncel bilgilerle birleştiren müzeler, tarihi mirası gözler önüne serme açısından önemli bir kaynak işlevi görmektedir. Müze gezileri, öğrencilerin derslerde gerçekleştirdikleri eğitim-öğretim etkinliklerini pekiştirerek öğrenmelerini kalıcı hale getirir ve kültürel etkinlikler aracılığıyla eğlenerek öğrenmelerine olanak tanımaktadır. Bu nedenle, müze ziyaretleri tıp eğitiminde tıp tarihi, etik ve deontoloji gibi konu alanlarında oldukça eşsiz öğrenme fırsatları sunmaktadır

description: This chapter discusses the dynamical properties of eruptive prominences in relation to coronal mass ejections (CMEs). The fact that eruptive prominences are a part of CMEs is emphasized in terms of their physical association and kinematics. The continued propagation of prominence material into the heliosphere is illustrated using in-situ observations. The solar-cycle variation of eruptive prominence locations is discussed with a particular emphasis on the rush-to-the-pole (RTTP) phenomenon. One of the consequences of the RTTP phenomenon is polar CMEs, which are shown to be similar to the low-latitude CMEs. This similarity is important because it provides important clues to the mechanism by which CMEs erupt. The nonradial motion of CMEs is discussed, including the deflection by coronal holes that have important space weather consequences. Finally, the implications of the presented observations for the modeling CME modeling are outlined.

description: Galaxies display several well-behaved scaling relations between their properties, such as the star formation rate-stellar mass relation (the main sequence) and the stellar mass-halo mass relation (SHMR). In principle, these scaling relations could imply different star formation histories (SFHs) of galaxies and different constraints on galaxy formation physics. In this paper, we derive the SFHs of galaxies by assuming that they always follow the SHMRs at different redshifts and use an empirical model to constrain key processes in their baryon cycle. It is found that, besides cold accretion due to halo growth, outflow of gas produced by stellar feedback has to be recycled to sustain the derived SFHs of galaxies. The recycled fraction is strongly affected by the baryon fraction in accreted low-mass haloes and the mass loading factor which quantifies the ratio between the galactic outflow rate and star formation rate. Our fiducial model predicts that around $20-60\%$ of outflow is recycled in $\sim0.5-4Gyrs$, while simulations predict a slightly higher recycle fraction and a lower recycle time. We argue that strong constraints on the baryon cycle process can be obtained from future observation of the circum-galactic medium (CGM) of galaxies, such as the gas cooling rate of CGM. We also find that the implied SFHs from the SHMRs indicate that galaxies stay on the main sequences only for part of their lifetimes. Our model reproduces the evolution of the mass-metallicity relation as well.

description: We study a one-dimensional version of the Hopfield model with long, but finite range interactions below the critical temperature.In the thermodynamic limit we obtain large deviation estimates for the distribution of the "local" overlaps, the range of the interaction, γ-1, being the large parameter. We show in particular that the local overlaps in a typical Gibbs configuration are constant and equal to one of the mean-field equilibrium values on a scale o(γ-2). We also give estimates on the size of typical "jumps". i.e. the regions where transitions from one equilibrium value to another take place. Contrary to the situation in the ferromagnetic Kac-model, the structure of the profiles is found to be governed by the quenched disorder rather than by entropy.

The intra-hour variable quasar J1819$+$3845: 13-year evolution, jet polarization structure and interstellar scattering screen properties

description: We examine the long-term evolution of the intra-hour variable quasar, J1819+3845, whose variations have been attributed to interstellar scintillation by extremely local turbulent plasma, located only 1-3pc from Earth. The variations in this source ceased some time between June 2006 and February 2007. The evolution of the source spectrum and the long-term lightcurve, and the persistent compactness of the source VLBI structure indicates that the cessation of rapid variability was associated with the passage of the scattering material out of the line of sight to the quasar. We present an analysis of the linear polarization variations and their relation to total intensity variations. The proper motion of polarized features in the quasar jet is found to be subluminal. Systematic time delays between Stokes I, Q and U, in combination with the structure of the source obtained from 8.4GHz VLBI data, confirm the estimate of the screen distance: 1-2pc, making the screen one of the nearest objects to the Solar System. We determine the physical properties of this scattering material. The electron density in the scattering region is extremely high with respect to the warm ionized ISM, with an estimated density of $n_e \sim 97 \, l_0^{1/3} {ΔL}_{100}^{-1/2}$cm$^{-3}$, where $l_0$ is the outer scale of the turbulence in AU and $ΔL = 100 ΔL_{100}$ AU is the depth of the scattering region. If this plasma is in pressure balance with the local magnetic field, one expects a ~2 rad/m^2 rotation measure change associated with the passage of this material past the quasar. We examine the rotation measures of sources and the diffuse polarized emission in the surrounding region. We place a limit of 10 rad/m^2 on the RM change. The variability of sources near J1819+3845 is used to deduce that the screen must therefore be either very small (~100 AU) or patchy.

description: Objectif : L’objectif de ce travail est d’évaluer l’apport en pratique clinique de la TEMP/TDM, par rapport à la technique habituelle, pour l’évaluation de la fonction pulmonaire post-opératoire. Deux autres dimensions ont été intégrées à cette recherche : le temps de traitement et la dose supplémentaire. Matériel et méthode : 14 patients, ayant bénéficié d’une TEMP/TDM dans le cadre de la scintigraphie perfusée, sont inclus. Pour tous les patients, le volume expiratoire maximal en une seconde (VEMS) a été prédit, en utilisant les deux méthodes : planaire et TEMP/TDM. Pour analyser le temps supplémentaire, la phase de délimitation a été chronométrée. Afin de pouvoir quantifier la dose supplémentaire apportée par l’imagerie anatomique, la dose efficace des deux modalités a été calculée, et additionnées. Résultats : Les résultats montrent une bonne corrélation et une bonne concordance des deux méthodes testées. Il est remarqué que la méthode planaire tend à donner des valeurs prédictives plus élevées que la méthode TEMP/TDM. Le temps de traitement des images augmente en passant de 1.41±0.31 à 33.36±14.77 minutes. La TDM utilise des rayons X, ce qui implique une augmentation de la dose de l’examen de 75.9%. Conclusion : Les résultats confortent les conclusions obtenues dans différents articles. L’analyse semble indiquer que la méthode planaire tend à donner des résultats supérieurs. Sur la base des données recueillies, un réel apport en précision ne peut être démontré. En se basant sur la littérature consacrée à ce sujet, l’imagerie 3D semble apporter une fiabilité supérieure. Le temps de traitement augmente d’une méthode à l’autre. Dans tous les cas, la charge de travail ne dépasse pas une heure par patient. La dose est aussi augmentée, en utilisant la TEMP/TDM. Néanmoins, selon les niveaux de références diagnostiques, la dose de cet examen respecte le principe d’optimisation en radioprotection. Selon les dimensions observées, l’hypothèse est émise que cette technique est réalisable dans la routine médicale.

description: According to the public goods game (PGG) protocol, participants decide freely whether they want to contribute to a common pool or not, but the resulting benefit is distributed equally. A conceptually similar dilemma situation may emerge when participants consider if they claim a common resource but the related cost is covered equally by all group members. The latter establishes a reversed form of the original public goods game (R-PGG). In this work, we show that R-PGG is equivalent to PGG in several circumstances, starting from the traditional analysis, via the evolutionary approach in unstructured populations, to Monte Carlo simulations in structured populations. However, there are also cases when the behavior of R-PGG could be surprisingly different from the outcome of PGG. When the key parameters are heterogeneous, for instance, the results of PGG and R-PGG could be diverse even if we apply the same amplitudes of heterogeneity. We find that the heterogeneity in R-PGG generally impedes cooperation, while the opposite is observed for PGG. These diverse system reactions can be understood if we follow how payoff functions change when introducing heterogeneity in the parameter space. This analysis also reveals the distinct roles of cooperator and defector strategies in the mentioned games. Our observations may hopefully stimulate further research to check the potential differences between PGG and R-PGG due to the alternative complexity of conditions.

description: Genus Poliopogon Thomson (1877) Diagnosis Body is fan-like, where the concave side represents the atrial cavity. Basalia are in relatively broad tufts and include some monaxons with clavate distal ends and two-toothed anchors. Choanosomal, hypodermal and hypoatrial spicules are pentactines, rarely stauractines and tauactines. Uncinates usually consist of only one type. Dermalia and atrialia are pinular pentactines and rare hexactines. Microscleres are amphidiscs (from one to three kinds) and combinations of microhexactines and pentactines (in some species also stauractines, diactines, monactines and spheres) (Tabachnick & Menshenina, 2002).

description: Mature Large Granular lymphocytes (LGL) disorders include a spectrum of conditions, ranging from polyclonal to clonal indolent and/or overt leukemic LGL proliferations. Most cases are represented by clonal expansions of TCRα/β+ LGL displaying a CD8+ phenotype with expression of cytotoxic T-cell antigens (CD57, CD16, TIA-1, perforin and granzyme B). Proliferations of CD3-CD16+ NK cells with a restricted patter of NK receptors are less common, usually comprising 15% of the cases. Main features are cytopenias, splenomegaly and autoimmune phenomena. Morphology, immunophenotyping and molecular analyses are crucial to establish a correct diagnosis of disease. According to the 2008 WHO classification, two separate entities account for the majority of cases, T-LGL leukemia and Chronic Lymphoproliferative Disease of NK cell (this latter still provisional). Although these disorders are characterized by the expansion of different cells types i.e. T and NK cells, with specific genetic features and abnormalities, compelling evidence supports the hypothesis that a common pathogenic mechanism would be involved in both disorders. As a matter of fact, a foreign antigen driven clonal selection is considered the initial step in the mechanism ultimately leading to generation of both conditions. In this chapter we will discuss recent advances on the pathogenesis of chronic T and NK disorders of granular lymphocytes, challenging the current WHO classification on the opportunity to separate T and NK disorders, which are likely to represent two sides of the same coin.
