‘A Child of God Much Like Yourself Perhaps’. An Ecocritical Reading of Cormac McCarthy’s Child of God
Creators: name: Segato, Giulio
Publisher: name: Linguæ & - Journal of Modern Languages and Cultures
Year: 2022

description: Cormac McCarthy’s fiction has been widely studied through the lens of Ecocriticism, probably because nature plays a prominent role in his novels in which the setting is often a decisive narrative element. The most relevant environmental analyses concern The Trilogy Border novels, Blood Meridian and, of course, The Road, a post-apocalyptic novel fundamentally centered on the environment issue. The aim of this study is to investigate Child of God, the writer’s shortest novel, from an ecocritical point of view, despite the apparent absence of environmental characters in the book. Child of God could be actually seen as a McCarthy’s early concern with the twentieth-century industrial development’s impact on the environment: the early dissolution of the protagonist’s family farm, taken away by the State, for instance, coincides with the start of the human dissolution of the protagonist, a psychopath murderer. Here, McCarthy’s defiance of the environmentally reckless present is equated with the mental illness of the protagonist, Lester Ballard. By investigating one of McCarthy's most significant early novels through an ecocritical approach, it will be possible to better understand the author's environmental turning point in his late novels as well

description: Hirschsprung disease (HSCR) is one of neurocristopathies in children. It is mainly treated by surgery but causes severe complications. Enteric neural crest-derived cell (ENCC) transplantation is a potential radical therapeutic strategy; however, so far with poor efficacy. To assess the therapeutic benefit of fecal microbiota transplantation (FMT) on ENCC transplantation in treating HSCR and characterize underlying mechanisms. We compared the ENCC phenotype, gut microbiome and associated metabolites in hypoganglionosis rats with or without FMT. Then 16S rDNA sequencing and targeted mass spectrometry assays were performed to explore the potential key regulators. We also verified the therapeutic benefits of these regulators on ENCC transplantation and the underlying mechanisms based on transcriptome-wide mRNA sequencing. The intestinal microenvironment in hypoganglionosis negatively influenced the ENCC phenotype, while FMT could relieve this impact and promote ENCC transplantation. The abundance of some genera, particularly Bacteroides and Clostridium, increased after FMT, which coincided with short-chain fatty acid (SCFA) production. SCFAs stimulated ENCC proliferation, migration and supported ENCC transplantation. MAPK signaling was the top differentially regulated pathway, and the inhibitor of the MEK1/2 signaling abrogated the SCFA-mediated effect on ENCC. This study suggests that FMT promotes cell therapy for hypoganglionosis, which might involve gut microbiota metabolite short-chain fatty acid-induced MEK1/2 signaling pathway.

description: Depuis quelques années de nombreuses critiques sont émises par les enseignants et les étudiants sur l’efficience pédagogique des cours magistraux en amphithéâtre. La conception verticale de transmission du savoir est parfois mise en avant pour expliquer le décrochage et l’échec d’étudiants en première année. Constatant depuis quelques années une baisse des résultats lors des contrôles de connaissance et de manière concomitante une baisse de l’attention des étudiants pour un cours de première année, nous avons voulu renverser l’organisation d’un cours en laissant les étudiants préparer et animer cinq séances d’amphithéâtre avec le moins de consignes possibles. Après avoir présenté une conception de cours renversé et distingué le concept de celui de cours inversé, nous présenterons le contexte de la mise en place de ce dispositif pédagogique, ainsi que son évaluation. Enfin, nous nous interrogerons sur les conséquences d’une expérience de ce type sur la posture pédagogique des enseignants dans la problématique de l’apprendre ensemble. Flipping a lecture for first year students: The impacts on peer learning for Y generation. In recent years, numerous criticisms have been made by teachers and students on the pedagogical efficiency of lectures in amphitheater. The vertical design of knowledge transmission is sometimes put forward to explain the drop-out and failure of first-year students. In recent years, we noticed a drop in results during knowledge checks and concomitantly a drop in the attention of students for a first year course. We wanted then to reverse the organization of a course by letting the students prepare and animate themselves five sessions of lectures in amphitheater with the least possible instructions. After presenting a design of reversed course and clarifying the concept with the inverted course, we will present the context of the implementation of this pedagogical device, as well as its evaluation.

Weighted Area Under the Receiver Operating Characteristic Curve and Its Application to Gene Selection
Creators: name: Li, Jialiang

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Partial area under the ROC curve (PAUC) has been proposed for gene selection in Pepe et al. (2003) and thereafter applied in real data analysis. It was noticed from empirical studies that this measure has several key weaknesses, such as an inability to reflect nonuniform weighting of different decision thresholds, resulting in large numbers of ties. We propose the weighted area under the ROC curve (WAUC) in this paper to address the problems associated with PAUC. Our proposed measure enjoys a greater flexibility to describe the discrimination accuracy of genes. Nonparametric and parametric estimation methods are introduced, including PAUC as a special case, along with theoretical properties of the estimators. We also provide a simple variance formula, yielding a novel variance estimator for nonparametric estimation of PAUC, which has proven challenging in previous work. The proposed methods permit sensitivity analyses, whereby the impact of differing weight functions on gene rankings may be assessed and results may be synthesized across weights. Simulations and re-analysis of two well-known microarray datasets illustrate the practical utility of WAUC.

description: Experimental evidences indicate that formations of disks and planetary systems around pulsars are allowed. Unfortunately, direct detections through electromagnetic observations appear to be quite rare. In the case of PSR 1931+24, the hypothesis of a rigid precessing disk penetrating the pulsar light cylinder is found consistent with radio transient observations from this star. Disk self-occultation and precession may limit electromagnetic observations. Conversely, we show here that gravitational waves generated by disk precessing near the light cylinder of young and middle aged pulsars would be detected by future space interferometers with sensitivities like those expected for DECIGO (DECI-hertz Interferometer Gravitational Wave Observatory) and BBO (Big Bang Observer). The characteristics of circumpulsar detectable precessing disks are estimated as a function of distance from the Solar System. Speculations on upper limits to detection rates are presented.

description: $^{180m}$Ta is the longest-lived metastable state presently known. Its decay has not been observed yet. In this work, we report a new result on the decay of \mTa obtained with a $2015.12$-g tantalum sample measured for $527.7$ d with an ultra-low background HPGe detector in the STELLA laboratory of the Laboratori Nazionali del Gran Sasso (LNGS), in Italy. Before the measurement, the sample has been stored deep-underground for ten years, resulting in subdominant background contributions from cosmogenically activated $^{182}$Ta. We observe no signal in the regions of interest and set half-life limits on the process for the two channels EC and $β^-$: $T_{1/2,~\mathrm{EC}} > 1.6 \times 10^{18}$ yr and $T_{1/2,~β^-} > 1.1\times 10^{18}$ yr ($90$\% C.\,I.), respectively. We also set the limit on the $γ$ de-excitation / IC channel: $T_{1/2,~\mathrm{IC}} > 4.1 \times 10^{15}$ yr ($90$\% C.\,I.). These are, as of now, the most stringent bounds on the decay of $^{180m}$Ta worldwide. Finally, we test the hypothetical scenarios of de-excitation of $^{180m}$Ta by cosmological Dark Matter and constrain new parameter space for strongly-interacting dark-matter particle with mass up to $10^5$ GeV.

description: Il presente contributo si propone di illustrare alcune affinità fra due scrittori svizzeri di lingua tedesca appartenenti a due differenti epoche letterarie: Christian Kracht, autore contemporaneo particolarmente apprezzato dalla critica, e Robert Walser, eclettico scrittore della Moderne. Sullo sfondo di una breve analisi del rapporto intrattenuto da Kracht con la sua madrepatria e la sua cultura, verrà proposta una disamina di due opere ‘esemplari’ di questi autori – il romanzo Faserland e il ‘Prosastück’ Der Spaziergang – atta a mettere in luce evidenti somiglianze fra questi due testi e in generale nella poetica testuale e nella costruzione dell’identità autoriale – in particolare per quanto concerne la Selbstinszenierung (auto-messinscena) dell’autore nella finzione e nella realtà – dei due scrittori elvetici. This contribution aims to illustrate some affinities between two Swiss-German writers from two different literary periods: Christian Kracht, a contemporary author particularly appreciated by critics, and Robert Walser, an eclectic writer of the Moderne. After a brief analysis of Kracht’s relationship with his motherland and its culture, the paper will move on to an examination of two ‘exemplary’ works by these authors – the novel Faserland and the ‘Prosastück’ Der Spaziergang –, focusing on highlighting evident similarities between these two texts and in general in the textual poetics and in the construction of authorial identity – in particular with regard to the Selbstinszenierung (self-staging) of the author both in fiction and reality – of these two Swiss writers.

Year: 2022

description: In this work on code-switching we will discuss agreement relations which take place outside DP. In particular, we will tackle mixed Italian/English sentences containing an Italian compound ergative-type verb, where typically the past participle must agree in gender with the DP-syntactic subject. Specifically, we aim to test what gender the past participle preferably takes when the subject is an English monolingual DP or a mixed DP and, crucially, if the N-gender remains active and able to enter an agreement relation with the past participle. Data are obtained through an Acceptability Judgment Task administered to some adult Italian/English bilingual speakers. The results obtained and discussed will contribute to the debate on code-switching vs. borrowing, as well as on the architecture of the bilingual competence.

description: Under temperature or pressure tuning, tetragonal EuPd$_2$Si$_2$ is known to undergo a valence transition from nearly divalent to nearly trivalent Eu accompanied by a volume reduction. Albeit intensive work, its microscopic origin is still being discussed. Here, we investigate the mechanism of the valence transition under volume compression by $ab~initio$ density functional theory (DFT) calculations. Our analysis of the electronic and magnetic properties of EuPd$_2$Si$_2$ when approaching the valence transition shows an enhanced $c$-$f$ hybridization between localized Eu 4$f$ states and itinerant conduction states (Eu 5$d$, Pd 4$d$, and Si 3$p$) where an electronic charge redistribution takes place. We observe that the change in the electronic structure is intimately related to the volume reduction where Eu-Pd(Si) bond lengths shorten and, for the transition to happen, we trace the delicate balance between electronic bandwidth, crystal field splitting, Coulomb repulsion, Hund's coupling and spin-orbit coupling. In a next step we compare and benchmark our DFT results to surface-sensitive photoemission data in which the mixed-valent properties of EuPd$_2$Si$_2$ are reflected in a simultaneous observation of divalent and trivalent signals from the Eu $4f$ shell. The study serves as well to explore the limits of density functional theory and the choice of exchange correlation functionals to describe such a phenomenon as a valence transition.

description: The outcome dependent sampling scheme has been gaining attention in both the statistical literature and applied fields. Epidemiological and environmental researchers have been using it to select the observations for more powerful and cost-effective studies. Motivated by a study of the effect of in utero exposure to polychlorinated biphenyls on children’s IQ at age 7, in which the effect of an important confounding variable is nonlinear, we consider a semi-parametric regression model for data from an outcome-dependent sampling scheme where the relationship between the response and covariates is only partially parameterized. We propose a penalized spline maximum likelihood estimation (PSMLE) for inference on both the parametric and the nonparametric components and develop their asymptotic properties. Through simulation studies and an analysis of the IQ study, we compare the proposed estimator with several competing estimators. Practical considerations of implementing those estimators are discussed.

description: Nel saggio cercheremo di capire come i Disturbi Specifici di Apprendimento possano rendere complesso il processo di apprendimento e insegnamento di una lingua straniera, sia a livello di istruzione secondaria, sia a livello di formazione universitaria. Sebbene la normativa negli ultimi anni abbia fatto passi da gigante nei confronti degli studenti DSA riuscendo a favorire una didattica che possa definirsi sempre di più inclusiva, ancora oggi molto è da fare - particolarmente a livello universitario - per far sì che i ragazzi e le ragazze con questo tipo di disturbo di natura neurobiologica possano efficacemente seguire un corso di studi in lingue e culture straniere. Attraverso la realizzazione di percorsi individualizzati e personalizzati, l’Università di Urbino presenta un modello operativo innovativo e integrato in cui la gestione dei tempi, i materiali, la didattica e la valutazione riescono a valorizzare le differenze e le caratteristiche di ciascuno e a consentire un proficuo apprendimento linguistico.

The textual statistical analysis of nine biographical interviews in Nouvelle-Aquitaine and Bavaria examined the involvement of professionals and their identity-building in the face of public policies. On both sides of the Rhine, the analysis reveals remarkable differences in taking into account the institutional frameworks that would weigh on the conception of French practices and on the focus on the person in insertion considered the first partner by the German professionals.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Continuous shape change is represented as curves in the shape space. A method for checking the closeness of these curves to a geodesic is presented. Three large databases of short human motions are considered and shown to be well approximated by geodesics. The motions are thus approximated by two shapes on the geodesic and the rate of progress along the path. An analysis of facial motion data taken from a study of subjects with cleft lip or cleft palate is presented that allows the motion to be considered independently from the static shape. Inferential methods for assessing the change in motion are presented. The construction of predicted animated motions is discussed.

description: In this paper we demonstrate the detection of millimeter waves via Autler-Townes splitting in 85Rb Rydberg atoms. This method may provide an independent, atom-based, SI-traceable method for measuring mm-wave electric fields, which addresses a gap in current calibration techniques in the mm-wave regime. The electric- field amplitude within a rubidium vapor cell in the WR-10 waveguide band is measured for frequencies of 93 GHz, and 104 GHz. Relevant aspects of Autler-Townes splitting originating from a four-level electromagnetically induced transparency scheme are discussed. We measure the E-field generated by an open-ended waveguide using this technique. Experimental results are compared to a full-wave finite element simulation.

description: The Extremely Low Mass White Dwarfs (ELM WDs) and pre-ELM WDs are helium core white dwarfs with mass $<\sim 0.3M_{\odot}$. Evolution simulations show that a lower mass limit for ELM WDs exists at $\approx0.14M_{\odot}$ and no one is proposed by observation to be less massive than that. Here we report the discovery of a binary system, LAMOST J224040.77-020732.8 (J2240 in short), which consists of a very low mass hot star and a compact companion. Multi-epoch spectroscopy shows an orbital period $P_{orb} =$0.219658$\pm0.000002$ days and a radial velocity semi-amplitude $K1=318.5\pm3.3km/s$, which gives the mass function of 0.74$M_{\odot}$, indicating the companion is a compact star. The F-type low resolution spectra illustrate no emission features, and the temperature ($\sim 7400K$) is consistent with that from Spectral Energy Distribution fitting and multi-color light curve solution. The optical light curves, in ZTF g, r and i bands and Catalina V band, show ellipsoidal variability with amplitudes $\sim30\%$, suggesting that the visible component is heavily tidally distorted. Combining the distance from Gaia survey, the ZTF light curves are modeled with Wilson-Devinney code and the result shows that the mass of the visible component is $M1=0.085^{+0.036}_{-0.024}M_{\odot}$, and the mass of the invisible component is $M2=0.98^{+0.16}_{-0.09}M_{\odot}$. The radius of the visible component is $R1=0.29^{+0.04}_{-0.03}R_{\odot}$. The inclination angle is approximately between 60$^{\circ}$ and 90$^{\circ}$. The observations indicate the system is most likely a pre-ELM WD + WD/NS binary, and the mass of pre-ELM is possibly lower than the $0.14M_{\odot}$ theoretical limit.

description: The broken inversion symmetry at the surface of a metallic film (or, more generally, at the interface between a metallic film and a different metallic or insulating material) greatly amplifies the influence of the spin-orbit interaction on the surface properties. The best known manifestation of this effect is the momentum-dependent splitting of the surface state energies (Rashba effect). Here we show that the same interaction also generates a spin-polarization of the bulk states when an electric current is driven through the bulk of the film. For a semi-infinite jellium model, which is representative of metals with a closed Fermi surface, we prove as a theorem that, regardless of the shape of the confinement potential, the induced surface spin density at each surface is given by ${\bf S} =-γ\hbar {\bf \hat z}\times {\bf j}$, where ${\bf j}$ is the particle current density in the bulk, ${\bf \hat z}$ the unit vector normal to the surface, and $γ=\frac{\hbar}{4mc^2}$ contains only fundamental constants. For a general metallic solid $γ$ becomes a material-specific parameter that controls the strength of the interfacial spin-orbit coupling. Our theorem, combined with an {\it ab initio} calculation of the spin polarization of the current-carrying film, enables a determination of $γ$, which should be useful in modeling the spin-dependent scattering of quasiparticles at the interface.

Son analyse nous amène à constater que les pratiques de santé s’expliquent en observant les interactions entre facteurs individuels, environnementaux et comportementaux mais chercher à comprendre de quelle manière les individus exercent une influence sur leur santé, nous conduit surtout à observer le rôle central du processus d’apprentissage. How people reaching midlife manage their health In a society where health is at the heart of all concerns, changing one’s behavior can become a major issue. More than ever, every person is invited to become an actor of his own health life. We deliberately chose midlife to be the best period for our study on the process of self-regulation of one’s health. The analysis leads us to observe that health practices can be explained by observing the interactions between individuals, their environmental and behavioral factors in order to understand how people gradually influence their health-learning process.

description: Tout au long de la vie professionnelle, des individus issus de cultures et de générations différentes sont amenés à travailler ensemble. Ceci implique un nouveau questionnement de la notion de compétences sociales, à l’heure où les métiers évoluent et où il devient de plus en plus nécessaire de développer l’intelligence collective (Bellier, 2000). Cet article propose de rendre compte d’une étude exploratoire, pour tenter de déterminer l’influence de la diversité socio-culturelle et générationnelle sur l’engagement et le développement des individus. A partir de l’articulation des cadres théoriques et méthodologiques du cours d’action (Theureau, 2004, 2006) et de l’approche sociotechnique (Albero, 2010), il s’agit d’identifier l’incidence des interactions issues d’un collectif pluriel sur la construction de l’expérience individuelle (Zeitler, Guérin et Barbier, 2012), au sein d’un environnement de formation qui mobilise pédagogie active et approche par l’expérience. Sharing and construction of intergenerational experience in training situation Throughout the professional life, individuals stemming from cultures and from different generations are brought to work together.This implies a new questioning of the concept of social skills, when the jobs evolve and when it becomes increasingly necessary to develop the collective intelligence (Bellier, 2000).This article suggests reporting an exploratory study, to try to determine the influence of sociocultural and generational diversity on the individuals’ motivation and development.From the articulation of the theoretical and methodological scopes of “cours d’action” (Theureau, 2004, 2006) and “approche sociotechnique” (Albero, 2010), it is a question of identifying the incidence of the interactions stemming from a plural collective on construction of the individual experiment (Zeitler, Guérin & Barbier, 2012), within an environment of formation which mobilizes active pedagogy and approach by the experiment.

description: Alkali antimonide semiconductor photocathodes provide a promising platform for the generation of high brightness electron beams, which are necessary for the development of cutting-edge probes including x-ray free electron lasers and ultrafast electron diffraction. However, to harness the intrinsic brightness limits in these compounds, extrinsic degrading factors, including surface roughness and contamination, must be overcome. By exploring the growth of CsxSb thin films monitored by in situ electron diffraction, the conditions to reproducibly synthesize atomically smooth films of CsSb on 3C-SiC (100) and graphene coated TiO2 (110) substrates are identified, and detailed structural, morphological, and electronic characterization is presented. These films combine high quantum efficiency in the visible (up to 1.2% at 400 nm), an easily accessible photoemission threshold of 550 nm, low surface roughness (down to 600 pm on a 1 um scale), and a robustness against oxidation up to 15 times greater then Cs3Sb. These properties suggest that CsSb has the potential to operate as an alternative to Cs$_3$Sb in electron source applications where the demands of the vacuum environment might otherwise preclude the use of traditional alkali antimonides.

Rappresentazioni ironiche dell’ideologia della True Womanhood. Il caso di “The Fullness of Life” di Edith Wharton

description: The present essays suggests a new reading of "The Fullness of Life", a short story composed by Edith Wharton in 1893. It is my contention that the critics have devoted far too little attention to this piece, above all by focusing solely on the autobiographical resonance of the text’s subject matter: an unhappy marriage between an idealistic aesthete and an unimaginative and materialistic man. While I do not deny its autobiographical value, I argue that the story deserves more critical attention, especially for what I see as its clever parody of the tenets of the so-called “pious novels”. More precisely, I contend that, by means of a literal and deeply ironic representation of the “domestic angel” metaphor, Wharton captures the conflict between women’s right to self-determination and the expectations of society in the second half of the nineteenth century – a society which objectified women by forcing them into a rigid domestic role dictated by the so-called “True Womanhood”.

description: The tilt of the velocity ellipsoid is a helpful tracer of the gravitational potential of the Milky Way. In this paper, we use nearly 140,000 RC stars selected from the LAMOST and Gaia to make a detailed analysis of the tilt of the velocity ellipsoid for various populations, as defined by the stellar ages and chemical information, within 4.5 $\leq$ $R$ $\leq$ 15.0 kpc and $|Z|$ $\leq$ 3.0 kpc. The tilt angles of the velocity ellipsoids of the RC sample stars are accurately described as $α$ = $α_{0}$ $\mathrm{arctan}$ ($Z$/$R$) with $α_{0}$ = (0.68 $\pm$ 0.05). This indicates the alignment of velocity ellipsoids is between cylindrical and spherical, implying that any deviation from the spherical alignment of the velocity ellipsoids may be caused by the gravitational potential of the baryonic disk. The results of various populations suggest that the $α_{0}$ displays an age and population dependence, with the thin and thick disks respectively values $α_{0}$ = (0.72 $\pm$ 0.08) and $α_{0}$ = (0.64 $\pm$ 0.07), and the $α_{0}$ displays a decreasing trend with age (and [$α$/Fe]) increases, meaning that the velocity ellipsoids of the kinematically relaxed stars are mainly dominated by the gravitational potential of the baryonic disk. We determine the $α_{0} - R$ for various populations, finding that the $α_{0}$ displays oscillations with $R$ for all the different populations. The oscillations in $α_{0}$ appear in both kinematically hot and cold populations, indicating that resonances with the Galactic bar are the most likely origin for these oscillations.

description: The simple, longitudinal, and transverse wobblers are systematically studied within the framework of collective Hamiltonian, where the collective potential and mass parameter included are obtained based on the tilted axis cranking approach. Solving the collective Hamiltonian by diagonalization, the energies and the wave functions of the wobbling states are obtained. The obtained results are compared with those by harmonic approximation formula and particle rotor model. The wobbling energies calculated by the collective Hamiltonian are closer to the exact solutions by particle rotor model than harmonic approximation formula. It is confirmed that the wobbling frequency increases with the rotational frequency in simple and longitudinal wobbling motions while decreases in transverse wobbling motion. These variation trends are related to the stiffness of the collective potential in the collective Hamiltonian.

description: This study investigates the overall topic compositions and traces of right-wing populist partisanship in the content structures of German-language digital alternative news outlets. We argue that a topically heterogeneous landscape of right-wing populist alternative news outlets could maximize the reach of right-wing populist messages. Using LDA topic modeling, we explore the topical structures of nine different outlets (n = 66,965 articles) and empirically identify meaningful groups of outlets. Our analyses suggest the existence of two topically heterogeneous clusters of alternative news media: (1) core right-wing populist outlets, with around 45–50% of articles coming from topics that are related to right-wing or populist politics; and (2) topically diverse outlets. The latter group's topic selection also reveals right-wing populist partisanship, but less prominently so, while putting more emphasis on general interest news topics, such as sports, economy, or international relations. This group also includes Russian state-owned RT deutsch and Falun Gong-affiliated Epoch Times whose institutional roots, however, are only partially reflected in their topic selection. Additionally, longitudinal analyses reveal an increase of populism-related topics in both groups around the election date of the 2017 German federal election.
Current Concepts on Diagnosis and Treatment of Mastocytosis

description: Mastocytosis is a heterogeneous group of disorders characterized by a clonal proliferation and accumulation of mast cells in one or more organ, primarily in the skin and bone marrow. The clinical spectrum of the disease varies from relatively benign forms with isolated skin lesions to very aggressive variants with extensive systemic involvement and poor prognosis. The growth and proliferation of clonal mast cells is caused by an activating mutation of the tyrosine kinase receptor Kit for Stem Cell Factor, the main growth factor for mast cells. Clinical symptoms are related to mast-cell mediator release, to the tissue mast cell infiltration or both. The degree of infiltration and cell activation determines the highly variable clinical and morphological features. Current treatment of mastocytosis includes symptomatic, antimediator drugs and cytoreductive targeted therapies.
Current enhancement through a time dependent constriction in fractional topological insulators

description: We analyze the backscattering current induced by a time dependent constriction as a tool to probe fractional topological insulators. We demonstrate an enhancement of the total current for a fractional topological insulator induced by the dominant tunneling excitation, contrary to the decreasing present in the integer case for not too strong interactions. This feature allows to unambiguously identify fractional quasiparticles. Furthermore, the dominant tunneling processes, which may involve one or two quasiparticles depending on the interactions, can be clearly determined.

description: The emergence of multidrug-resistant bacteria has become a significant global health concern, and lytic bacteriophage or phage has been proposed as a promising alternative. Nevertheless, finding phages capable of targeting a broad range of hosts remains a significant challenge. Our study introduces two lytic phages—iPHaGe-KPN-11i and iPHaGe-KPN-12i—belonging to the Pseudotevenvirus genus within the Straboviridae family. These phages were isolated from hospital effluent and specifically targeted extended-spectrum cephalosporin-resistant Klebsiella pneumoniae. When cultured on a double-layer agar plate, both phages produced clear, circular, haloed plaques of approximately 0.8±0.2 mm in diameter. Their whole genome sequences differed in terms of size and number of encoded proteins. The genome of iPHaGe-KPN-11i consist of 177603 base pairs genome (44.9% GC) with 273 coding sequences (CDS), encoding 148 hypothetical proteins and two tRNAs. While iPHaGe-KPN-12i genome is marginally larger with 178179 base pairs (44.7% GC content) and 275 CDS, encoding 152 hypothetical proteins and two tRNAs. Each phage was found to possess a single endolysin gene, predicted to be phage_lysozyme (PF00959.22), which demonstrated the capability of lysing at least 14 distinct bacterial species in vitro. The spectrum of their lytic activity was examined using a direct spot test against other bacterial species (n=27) derived and sequenced from clinical samples. iPHaGe-KPN-11i showed lytic activity against 12 (44.5%) strains, with clear lysis zones in four. iPHaGe-KPN-12i was active against 13 (48.1%) strains, five of which displayed clear lysis zones. Unlike many phages which are specific to one bacterial species, iPHaGe-KPN-11i and iPHaGe-KPN-12i exhibited a broader lytic spectrum; enabling the opportunity to use them in phage cocktails for host range expansion with further evaluations and could be a beacon of hope in the looming darkness of the AMR crisis.
Génération-s Dessau : quelles influences de la Reformpädagogik des philanthropistes sur leurs élèves ?

description: Cet article propose de détailler le parcours de trois élèves formés aux méthodes des philanthropinistes à la fin du XVIIIe. Il s’agit du négociant Nikolaus von Böhl, du géographe Carl Ritter et du comte Ernst Friedrich Herbert zu Münster. Cela permettra une analyse sociologique : quelles professions, quelles ouvertures intellectuelles, quels engagements civiques, politiques ont-ils été rendus possible par l'enseignement ? Les parcours des élèves sont variés. Mais, bien souvent, au-delà de professions, on observe une survivance des formes d'humanisme philanthropique. Et on peut répertorier quelles sont ces formes et comment elles s'ajustent aux nouvelles conjonctures politiques, militaires, sociales, économiques. En somme, il s’agira d’étudier quelles valeurs sont ainsi transmises. Philanthropism is a well-known educational reform in Germany at the end of the eighteenth century. The Philanthropinum of Dessau served as a model for the institutions founded after him, such as Salzmann’s school in Schnepfenthal or Campe’s pension in Hamburg. In the context of this topic "Learning together, in and between generations", we are focused on the career of three pupils from these schools. We intend to answer these questions. How do we learn generationally? Which is the influence on the relationship of learners and teachers? Through a sociological analysis, we will underline the values that connect across generations

description: In complex survey sampling, a fraction of a finite population is sampled. Often, the survey is conducted so that each subject in the population has a different probability of being selected into the sample. Further, many complex surveys involve stratification and clustering. For generalizability of the sample to the finite population, these features of the design are usually incorporated in the analysis. While the Wilcoxon rank sum test is commonly used to compare an ordinal variable in bivariate analyses, no simple extension of the Wilcoxon rank sum test has been proposed for complex survey data. With multinomial sampling of independent subjects, the Wilcoxon rank-sum test statistic equals the score test statistic for the group effect from a proportional odds cumulative logistic regression model for an ordinal outcome. Using this regression framework, for complex survey data, we formulate a similar proportional odds cumulative logistic regression model for the ordinal variable, and use an estimating equations score statistic for no group effect as an extension of the Wilcoxon test. The proposed method is applied to a complex survey designed to produce national estimates of the health care use, expenditures, sources of payment, and insurance coverage.
