description: We study the Lamb shift of a two-level atom arising from its coupling to the conformal massless scalar field, which satisfies the Dirichlet boundary conditions, in the Hartle-Hawking vacuum in the BTZ spacetime, and find that the Lamb shift in the BTZ spacetime is structurally similar to that of a uniformly accelerated atom near a perfectly reflecting boundary in (2+1)-dimensional flat spacetime. Our results show that the Lamb shift is suppressed in the BTZ spacetime as compared to that in the flat spacetime as long as the transition wavelength of the atom is much larger than $AdS$ radius of the BTZ spacetime while it can be either suppressed or enhanced if the transition wavelength of the atom is much less than $AdS$ radius. In contrast, the Lamb shift is always suppressed very close to the horizon of the BTZ spacetime and remarkably it reduces to that in the flat spacetime as the horizon is approached although the local temperature blows up there.

description: Restriction enzyme-mediated events (REM events; integration of transforming DNA catalyzed by in vivo action of a restriction enzyme) and illegitimate recombination events (IR events; integration of transforming DNA that shares no homology with the host genomic sequences) have been previously characterized in Saccharomyces cerevisiae. This study determines the effect of mutations in genes that are involved in homologous recombination and/or in the repair of double-stranded DNA breaks on these recombination events. Surprisingly, REM events are completely independent of the double-strand-break repair functions encoded by the RAD51, RAD52, and RAD57 genes but require the RAD50 gene product. IR events are under different genetic control than homologous integration events. In the rad50 mutant, homologous integration occurred at wild-type frequency, whereas the frequency of IR events was 20- to 100-fold reduced. Conversely, the rad52 mutant was grossly deficient in homologous integration (at least 1,000-fold reduced) but showed only a 2- to 8-fold reduction in IR frequency.

description: Disorder is a key factor influencing the behavior of condensed states of matter, however the true extent of its impact is generally difficult to determine due to the prominent roles played by quantum interference, entanglement between spin and orbital degrees of freedom and proximity to quantum critical points. Here we show that the one-particle disorder self-energy -- a direct probe of the renormalization of low-energy excitations due to defects and impurities distributed randomly in a crystal -- can be obtained by means of unbiased spectral expansions of lattice Green's functions in a computationally expedient manner. Our scheme provides a powerful framework to map out the frequency and wavevector dependence of electronic excitations in unprecedented large tight-binding systems, up to $10^9$ orbitals, with energy resolution only limited by the mean level spacing. We demonstrate the versatility of our approach in 3 distinct problems: (i) the Gade singularity in honeycomb layers with dilute topological defects; (ii) the rich landscape of impurity resonances in a spin-orbit-coupled ferromagnet; and (iii) the tailoring of emergent s-wave and p-wave superconducting phases in graphene via atomic defects. These examples reveal rich features in the disorder self-energy $Σ_{\textrm{dis}}(\mathbf{k},ω)$ that are absent from the self-consistent T-matrix approach and other common approximation schemes, which include regimes of nontrivial wavevector dependence and anomalous dependence upon the impurity concentration. Our study unravels puzzling, and so far largely inaccessible, manifestations of strong nonperturbative quantum interference effects in quantum materials and disordered phases of matter.

Evidence for a role of the Drosophila melanogaster suppressor of sable gene in the pre-mRNA splicing pathway.

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

description: Recessive mutations of the Drosophila melanogaster suppressor of sable [su(s)] gene result in elevated accumulation of RNA from vermilion (v) mutant alleles that have an insertion of the 7.5-kb retrotransposon 412 in the first exon of the v gene. During transcription of such a v mutant gene, the 412 sequences are incorporated into the primary transcripts and are subsequently removed by splicing at cryptic sites within 412 sequences. In a su(s)+ background, the level of these unusually spliced transcripts is exceedingly low, and su(s) mutations increase their accumulation. We previously proposed that v RNA levels are elevated in su(s) mutants because of increased recognition of the cryptic splice sites, and the aim of this study was to test this hypothesis. We generated a v mutant derivative with a smaller 412 insertion, introduced alterations into the 412-associated splice sites, and examined the effect of su(s) mutations on expression of these derivatives after germ line transformation. To increase overall expression levels, the v promoter was replaced with the stronger Metallothionein (Mtn) gene promoter. We found that transformants bearing a v derivative with 480 bp of 412 sequences accumulate both transcripts, with 412 sequences spliced out and transcripts that retain 412 sequences. Mutations of su(s) increase the levels of both transcript classes without affecting the relative amounts of the two forms. Strikingly, replacement of the cryptic 5' splice sites with a 5' consensus produces the same effect as, and eliminates the response to, a su(s) mutation. In addition, we demonstrated that mutations of su(s) lead to increased accumulation of v transcripts even when the previously identified cryptic 412 5' and 3' splice sites were destroyed and that other cryptic splice sites reside within Mtn and 412 sequences. These results indicate that the v mutant transcripts are stabilized by assembly of the 412 sequences into splicing complexes and support the hypothesis that splicing complexes more readily assemble on cryptic splice sites in su(s) mutants.

description: At the millimeter scale and in the intermediate Reynolds number (Re) regime, the midge and mosquito larvae can reach swimming speeds of more than one body length per cycle performing a "figure-of-8" gait, in which their elongated bodies periodically bend nearly into circles and then fully unfold. To elucidate the propulsion mechanism of this cycle of motion, we conducted a 3D numerical study which investigates the hydrodynamics of undergoing the prescribed kinematics. Novel propulsion mechanisms, such as modulating the body deformation rate to dynamically increase the maximum net propulsion force, using asymmetric kinematics to generate torque and the appropriate rotation, and controlling the radius of the curled body to manipulate the moment of inertia. The figure-of-8 gait is found to achieve propulsion at a wide range of Re, but is most effective at intermediate Re. The results were further validated experimentally, via the development of a soft millimeter-sized robot that can reach comparable speeds using the figure-of-8 gait.

description: The emission cascade of a single quantum dot is a promising source of entangled photons. A prerequisite for this source is the use of a symmetric dot analogous to an atom in a vacuum, but the simultaneous achievement of structural symmetry and emission in a telecom band poses a challenge. Here we report the growth and characterization of highly symmetric InAs/InAlAs quantum dots self-assembled on C3v symmetric InP(111)A. The broad emission spectra cover the O (1.3 micron-m), C (1.55 micron-m), and L (1.6 micron-m) telecom bands. The distribution of the fine-structure splittings is considerably smaller than those reported in previous works on dots at similar wavelengths. The presence of dots with degenerate exciton lines is further confirmed by the optical orientation technique. Thus, our dot systems are expected to serve as efficient entangled photon emitters for long-distance fiber-based quantum key distribution.

description: L’autore traccia un profilo completo della personalità del pittore irpino del Novecento Mario Pascale, un autentico maestro del figurativismo italiano. Si evidenziano la ricchezza tematica e l’esperienza maturata riprendendo modi e apporti dei maggiori esponenti della scuola dell’Ottocento a Napoli e a contatto con i protagonisti della pittura partenopea del primo Novecento. Si riscontra nei “ritratti” e negli “autoritratti”, oltre che nelle nature morte e nei poetici paesaggi della terra irpina, la nota di maggiore distinzione stilistica dell’artista che segna con la sua originale produzione pittorica la linea di continuità della migliore tradizione napoletana, meridionale più in generale, e con la modernità del Novecento italiano.
description: The author traces a complete profile of the personality of the twentieth-century Irpinia painter Mario Pascale, an authentic master of Italian figurativism. The thematic richness and experience gained by taking up the ways and contributions of the major exponents of the nineteenth century school in Naples and in contact with the protagonists of Neapolitan painting of the early twentieth century are highlighted. The note of his greatest stylistic distinction is marked by his original pictorial production according to the best Neapolitan tradition (more generally to southern Italy and the modernity of the Italian twentieth century). This distinction could be found in the “portraits” and “self-portraits”, as well as in the still lifes and poetic landscapes of the Irpinia area.

description: We address the dynamics of a two-qubit system interacting with a classical dephasing environment driven by a Gaussian stochastic process. Upon introducing the concept of entanglement-preserving time, we compare the degrading effects of different environments, e.g. those described by Ornstein-Uhlenbeck or fractional noise. In particular, we consider pure Bell states and mixtures of Bell states and study the typical values of the entanglement-preserving time for both independent and common environments. We found that engineering environments towards fractional Gaussian noise is useful to preserve entanglement as well as to improve its robustness against noise. We also address entanglement sudden death by studying the entanglement-survival time as a function of the initial negativity. We found that: i) the survival time is bounded from below by an increasing function of the initial negativity, ii) the survival time depends only slightly on the process used to describe the environment and exhibits typicality. Overall, our results show that engineering the environment has only a slight influence over the entanglement-survival time, i.e. the occurence of entanglement sudden-death, while it represents a valuable resource to increase the entanglement-preserving time, i.e. to maintain entanglement closer to the initial level for a longer interaction time.

description: La douleur non soulagée est un problème pour de nombreux patients atteints d’un cancer. En partant du principe que toute infirmière sera un jour amenée à s’occuper de patients souffrant d’un cancer, il est important d’explorer ce qui favorise une bonne gestion de la douleur dans le cadre de cette maladie. Au travers de cette revue de littérature, je me suis intéressée à la douleur cancéreuse et à son soulagement à partir des deux questions de recherche suivantes : Comment l’infirmière peut-elle contribuer à un meilleur soulagement de la douleur cancéreuse en milieu hospitalier, eu égard aux attentes et besoins des patients ? De quelle manière, l’approche de la douleur des soins palliatifs peut-elle venir enrichir la pratique infirmière en soins aigus ? Sur la base des résultats de sept articles de recherche scientifique, j’ai pu constater que les attentes et besoins des patients en regard de la gestion de la douleur se situent en grande partie sur un plan relationnel. Une communication de qualité et une relation de confiance soignantsoigné semblent optimiser la gestion de la douleur. Il semble également important pour les patients que les infirmières aient des connaissances spécifiques en rapport avec la douleur et les traitements antalgiques et qu’elles les mobilisent afin de répondre à leurs questions. Enfin, j’ai pu identifier que les patients adressés à des équipes de soins palliatifs obtiennent de meilleurs résultats en terme de gestion de la douleur. Ces différents éléments me permettent de suggérer que l’infirmière doit développer et mobiliser des compétences variées afin de répondre aux besoins et attentes que les patients ont en relation avec la gestion de leur douleur. De plus, une approche multidimensionnelle de la douleur doit être adoptée afin de favoriser une meilleure gestion de celle-ci et dès lors, optimiser son soulagement.

description: The promoter of the human major histocompatibility complex class II-associated invariant-chain gene (Ii) contains two NF-kappa B/Rel binding sites located at -109 to -118 (Ii kappa B-1) and -163 to -172 (Ii kappa B-2) from the transcription start site. We report here that the differential function of each of these NF-kappa B/Rel sites in several distinct cell types depends on cell-specific binding of NF-kappa B/Rel transcription factors. Ii kappa B-1 is a positive regulatory element in B-cell lines and in the Ii-expressing T-cell line, H9, but acts as a negative regulatory element in myelomonocytic and glia cell lines. In vivo protein-DNA contacts are detectable at Ii kappa B-1 in cell lines in which this site is functional as either a positive or negative regulator. Electrophoretic mobility supershift assays determine that members of the NF-kappa B/Rel family of transcription factors can bind to this site in vitro and that DNA-binding complexes that contain p50, p52, p65, and cRel correlate with positive regulation whereas the presence of p50 correlates with negative regulation. Ii kappa B-2 is a site of positive regulation in B-cell lines and a site of negative regulation in H9 T cells, myelomonocytic, and glial cell lines. In vivo occupancy of this site is observed only in the H9 T-cell line. Again, in vitro supershift studies indicate that the presence of p50, p52, p65, and cRel correlates with positive function whereas the presence of only p50 and p52 correlates with negative function. This differential binding of specific NF-kappa B/Rel subunits is likely to mediate the disparate functions of these two NF-kappa B/Rel binding sites.

description: The p53 tumor suppressor protein, which is commonly mutated in human cancers, has been shown to interact directly with virally encoded from papillomavirus, adenovirus, and simian virus 40. The disruption of p53 function may be required for efficient replication of certain viruses and may also play a role in the development of virally induced malignancies. Infection with Epstein-Barr virus (EBV) has been associated with the development of B-cell lymphomas and nasopharyngeal carcinoma. Here we show that the EBV immediate-early protein, BZLF1 (Z), which is responsible for initiating the switch from latent to lytic infection, can interact directly in vitro and in vivo with the tumor suppressor protein, p53. This interaction requires the coiled-coil dimerization domain of the Z protein and the carboxy-terminal portion of p53. Overexpression of wild-type p53 inhibits the ability of Z to disrupt viral latency. Likewise, Z inhibits p53-dependent transactivation in lymphoid cells. The direct interaction between Z and p53 may play a role in regulating the switch from latent to lytic viral infection.

description: Certain thalassemic human beta-globin pre-mRNAs carry mutations that generate aberrant splice sites and/or activate cryptic splice sites, providing a convenient and clinically relevant system to study splice site selection. Antisense 2'-O-methyl oligoribonucleotides were used to block a number of sequences in these pre-mRNAs and were tested for their ability to inhibit splicing in vitro or to affect the ratio between aberrantly and correctly spliced products. By this approach, it was found that (i) up to 19 nucleotides upstream from the branch point adenosine are involved in proper recognition and functioning of the branch point sequence; (ii) whereas at least 25 nucleotides of exon sequences at both 3' and 5' ends are required for splicing, this requirement does not extend past the 5' splice site sequence of the intron; and (iii) improving the 5' splice site of the internal exon to match the consensus sequence strongly decreases the accessibility of the upstream 3' splice site to antisense 2'-O-methyl oligoribonucleotides. This result most likely reflects changes in the strength of interactions near the 3' splice site in response to improvement of the 5' splice site and further supports the existence of communication between these sites across the exon.

description: In preparation to make the most of our own planned James Webb Space Telescope investigations, we take advantage of publicly available calibration and early-science observations to independently derive and test a geometric-distortion solution for NIRCam detectors. Our solution is able to correct the distortion to better than ~0.2 mas. Current data indicate that the solution is stable and constant over the investigated filters, temporal coverage, and even over the available filter combinations. We successfully tested our geometric-distortion solution in three cases: (i) field-object decontamination of M 92 field; (ii) estimate of internal proper motions of M 92; and (iii) measurement of the internal proper motions of the Large Magellanic Cloud system. To our knowledge, the here-derived geometric-distortion solution for NIRCam is the best available and we publicly release it, as many other investigations could potentially benefit from it. Along with our geometric-distortion solution, we also release a Python tool to convert the raw-pixels coordinates of each detector into distortion-free positions, and also to put all the ten detectors of NIRCam into a common reference system.

description: Notre revue de littérature, effectuée entre la 2ème et la 3ème année bachelor, porte sur le rôle infirmier concernant l'utilisation des médecines complémentaires dans le but d'améliorer le bien-être chez des enfants souffrant de cancer. Les buts de ce travail sont de déterminer la prévalence de l'utilisation des médecines complémentaires, d'explorer leurs effets positifs ou négatifs sur le bien-être de l'enfant et de trouver des pistes d'interventions infirmières concrètes afin de mettre en lumière les différentes dimensions du rôle infirmier relié à ce thème actuel. Pour répondre à notre problématique, nous nous sommes appuyées sur huit articles de recherche infirmière trouvés sur différentes bases de données. Ces articles s'intéressent tous à l'enfant souffrant de cancer qui fait l'expérience de l'utilisation d'une médecine complémentaire. La discussion qui découle de l'analyse des articles de recherche permet de répondre à notre problématique en mettant en évidence les différents pans du rôle infirmier. L'infirmière doit tout d'abord développer une sensibilité quant aux médecines complémentaires et faire preuve d'une ouverture d'esprit. Un des rôles phare de l'infirmière est la notion de transmission d'informations aux enfants et parents désireux de connaître et d'utiliser une médecine complémentaire. Elle fait également le lien entre les différents médecins et les familles ; elle joue donc un rôle de médiateur. Ces rôles pourront être développés à l'aide d'une formation infirmière qui prendrait en considération l'essor de ces médecines et qui inclurait leur enseignement dans le programme. Pour terminer, nous présentons des perspectives de recherches qu'il serait intéresant de mener afin d'approfondir la thématique de notre travail.

description: The Ras(17N) dominant negative antagonizes endogenous Ras function by forming stable, inactive complexes with Ras guanine nucleotide exchange factors (GEFs; e.g., SOS1). We have used the growth-inhibitory phenotype of Ras(17N) to characterize two aspects of Ras interaction with GEFs. First, we used a nonprenylated version of Ras(17N), designated Ras(17N/186S), which no longer associates with the plasma membrane and lacks the growth-inhibitory phenotype, to address the importance of Ras subcellular location and posttranslational modification for its interaction with GEFs. We observed that addition of an N-terminal myristylation signal to Ras(17N/186S) restored the growth-inhibitory activity of nonprenylated Ras(17N). Thus, membrane association, rather than prenylation, is critical for Ras interaction with Ras GEFs. Second, we used a biological selection approach to identify Ras residues which are critical for Ras(17N) growth inhibition and hence for interaction with Ras GEFs. We identified mutations at residues 75, 76, and 78 that abolished the growth-inhibitory activity of Ras(17N). Since GEF interaction is dispensable for oncogenic but not normal Ras function, our demonstration that single-amino-acid substitutions at these three positions impaired the transforming activity of normal but not oncogenic Ras provides further support for the role of these residues in Ras-GEF interactions. Finally, Ras(WT) proteins with mutations at these residues were no longer activated by mammalian SOS1. Altogether, these results suggest that the Ras intracellular location and Ras residues 75 to 78 are critical for Ras-GEF interaction.

description: We rederive the number density of intervening line-of-sight haloes relative to lens subhaloes in galaxy-galaxy strong lensing observations, where these perturbers can generate detectable image fluctuations. Previous studies have calculated the detection limit of a line-of-sight small-mass dark halo by comparing the lensing deflection angles it would cause, to those caused by a subhalo within the lens. However, this overly simplifies the difference in observational consequences between a subhalo and a line-of-sight halo. Furthermore, it does not take into account degeneracies between an extra subhalo and the uncertain properties of the main lens. More in keeping with analyses of real-world observations, we regard a line-of-sight halo as detectable only if adding it to a smooth model generates a statistically significant improvement in the reconstructed image. We find that the number density of detectable line-of-sight perturbers has been overestimated by as much as a factor of two in the previous literature. For typical lensing geometries and configurations, very deep imaging is sensitive to twice as many line-of-sight perturbers as subhaloes, but moderate depth imaging is sensitive to only slightly more line-of-sight perturbers than subhaloes.

description: This paper presents novel Weighted Finite-State Transducer (WFST) topologies to implement Connectionist Temporal Classification (CTC)-like algorithms for automatic speech recognition. Three new CTC variants are proposed: (1) the "compact-CTC", in which direct transitions between units are replaced with back-off transitions; (2) the "minimal-CTC", that only adds self-loops when used in WFST-composition; and (3) the "selfless-CTC" variants, which disallows self-loop for non-blank units. Compact-CTC allows for 1.5 times smaller WFST decoding graphs and reduces memory consumption by two times when training CTC models with the LF-MMI objective without hurting the recognition accuracy. Minimal-CTC reduces graph size and memory consumption by two and four times for the cost of a small accuracy drop. Using selfless-CTC can improve the accuracy for wide context window models.

description: Le produit du travail que nous avons réalisé se présente sous la forme d’une revue de littérature dont l’élaboration s’étend sur une période d’environ une année et demie. La problématique a rencontré de nombreuses modifications en cours de développement, mais a finalement abouti au questionnement suivant : « Dans quelle mesure le massage contribue-t-il au soulagement de la douleur chez l’enfant atteint de maladie chronique et quels en sont les bénéfices pour la pratique infirmière ? ». Ce travail a pour objectifs : - d’acquérir des connaissances relatives aux bienfaits du massage sur l’enfant souffrant de douleurs - de reconnaître les bénéfices de celui-ci dans la pratique infirmière quotidienne. Ces connaissances et apprentissages permettront éventuellement d’étoffer une argumentation en faveur du massage. Celle-ci pourra alors être utilisée pour proposer cette pratique aux différents acteurs concernés. La méthodologie utilisée a débuté par la recherche d’informations concernant le recours aux massages, dans des situations de douleurs chez les enfants, au travers d’ouvrages professionnels. Après avoir développé notre problématique et sa pertinence pour la profession infirmière, nous avons réalisé des recherches dans les bases de données à notre disposition ; ceci afin d’apprécier et d’évaluer les données scientifiques à ce sujet. Au moyen des connaissances acquises, nous avons ensuite développé des pistes de réponses à notre problématique, puis avons mis en lumière certaines perspectives possibles. Les résultats obtenus ont confirmé que l’intégration des massages dans la prise en soins de la douleur chez les enfants suscite un questionnement qui a débuté il y a déjà plusieurs années et qui nécessite d’être confirmé par d’autres données scientifiques. Nous avons trouvé des réponses favorables à l’utilisation des massages dans le traitement de la douleur, mais également plus spécifiquement d’autres effets parallèles. Nous avons mis en évidence des perspectives qui permettront d’envisager quelques pistes en faveur de l’introduction des massages en tant que soin chez les enfants souffrant de douleurs. Finalement, cette revue de littérature apporte des informations relatives aux effets bénéfiques que les massages peuvent avoir sur l’enfant ainsi que pour les infirmiers et développe certaines perspectives destinées à valoriser et à promouvoir ce soin.

description: Standard optical imaging is diffraction-limited and lacks the resolving power to visualize many of the organelles and proteins found within the cell. The advent of super-resolution techniques overcame this barrier, enabling observation of subcellular structures down to tens of nanometers in size; however these techniques require or are typically applied to fixed samples. This raises the question of how well a fixed-cell image represents the system prior to fixation. Here we present the addition of live-cell Super-Resolution Optical Fluctuation Imaging (SOFI) to a previously reported correlative process using Single Molecule Localization Microscopy (SMLM) and Atomic Force Microscopy (AFM). SOFI was used with fluorescent proteins and low laser power to observe cellular ultrastructure in live COS-7 cells. SOFI-SMLM-AFM of microtubules showed minimal changes to the microtubule network in the 20 min between live-cell SOFI and fixation. Microtubule diameters were also analyzed through all microscopies; SOFI found diameters of 249 ± 68 nm and SMLM was 71 ± 33 nm. AFM height measurements found microtubules to protrude 26 ± 13 nm above the surrounding cellular material. The correlation of SMLM and AFM was extended to two-color SMLM to image both microtubules and actin. Two target SOFI was performed with various fluorescent protein combinations. rsGreen1-rsKAME, rsGreen1-Dronpa, and ffDronpaF-rsKAME fluorescent protein combinations were determined to be suitable for two target SOFI imaging. This correlative application of super-resolution live-cell and fixed-cell imaging revealed minimal artifacts created for the imaged target structures through the sample preparation procedure and emphasizes the power of correlative microscopy.

description: Fortement interpellés par des situations de refus de soins émanant de personnes âgées institutionnalisées capables de discernement et par la façon dont les équipes y répondaient, nous avons décidé d’explorer cette thématique sous l’angle du refus alimentaire, puisque l’alimentation en gériatrie est un soin à part entière. La question à laquelle nous avons cherché à répondre par cette revue de littérature est : Comment prendre en soin une personne âgée institutionnalisée ayant sa capacité de discernement et refusant de s’alimenter, de façon éthique ? L’analyse des neuf articles retenus nous a permis d’évoquer les raisons pouvant être à l’origine du refus alimentaire de la personne soignée, de faire un lien entre l’attitude soignante face au refus alimentaire et la maltraitance, et d’identifier les refus alimentaires comme des sources de conflits pour les soignants. Nous avons également pu mettre en évidence les attitudes soignantes recommandées. En amont de la problématique, il s’agit de soigner la qualité de la relation, de respecter les souhaits des personnes soignées concernant les repas et le cadre dans lequel ils sont pris, ainsi que de se former, afin d’être en mesure de les soutenir dans leurs choix. Face au refus alimentaire, il est essentiel d’évaluer la demande tout en respectant une démarche éthique, et après une prise de position, il s’agit de continuer à accompagner la personne.

description: La dépression post-partum (DPP) concerne environ 15% des femmes ayant accouché. Cette maladie affecte non seulement la mère et l'enfant en bas âge, mais également toute la famille. Parmi les immigrées, celles d'origine subsaharienne forment la population la plus vulnérable. Fragilisées par leur situation socio-économique et les sources de stress liées à l'immigration, elles sont particulièrement exposées aux maladies. Compte tenu de ces faits, du vécu des infirmières de la petite enfance à domicile et mes propres expériences, je me suis posé la question : "comment prévenir la DPP chez les femmes immigrées subsahariennes ?" Le but de cette revue de littérature est de découvrir les meilleures pratiques d'accompagnement permettant de prévenir la DPP chez les immigrées d'origine subsaharienne afin d'améliorer leur qualité de vie. La recherche d'articles scientifiques, sur les bases de données internationales, a ciblé les soins de prévention de DPP dans le contexte du soin culturel. Elle s'est appuyée sur des études publiées dans des revues avec comité de lecture. Selon les résultats, les femmes immigrées sont une population particulièrement à risque de développer la DPP en raison de leur situation socio-économique et, plus précisément, leur statut d'immigrante, leurs croyances culturelles et leurs difficultés linguistiques. Les mesures de prévention de la DPP incluent : l'écoute des patientes, la présence d'interprètes dans les situations-clé, le respect des pratiques religieuses et culturelles, le soutien psychosocial si besoin et du matériel éducatif adapté. Enfin, la formation initiale et continue des infirmières doit comprendre le développement de leur compétence culturelle afin de mieux répondre aux besoins des femmes migrantes. Ce travail m'a permis de prendre conscience du caractère primordial du rôle propre des infirmières auprès des femmes face au risque de développer la DPP et l'importance de l'approche interculturelle.

description: It is considered in this work the phase transition patterns for a coupled two-scalar field system model under the combined effects of finite sizes and temperature. The scalar fields are taken as propagating in a D=4 Euclidean space with the usual periodic compactification in the Euclidean time direction (with dimension given by the inverse of the temperature) and also under a compact dimension in the space direction, which is restricted to size L. In the latter case, a Dirichlet boundary condition is considered. Finite-size variation of the critical temperature for the cases of symmetry restoration and inverse symmetry breaking are studied. At fixed finite-temperature values, the variation of the inverse correlation lengths with the size L might display a behavior analogous to reentrant phase transitions. Possible applications of our results to physical systems of interest are also discussed.

description: L’interculturalité dans les soins est une donnée qui se répand de plus en plus en Suisse : l'offre en soins de l'infirmière doit donc être améliorée. Maternité et interculturalité se déclinent très différemment selon les origines, impliquant une compréhension et une prise en charge plus engageante. La population turque en Suisse demeure encore un groupe à risque et nous amène à nous poser la question suivante : l’interculturalité dans les soins : quel accompagnement infirmier offrir à une parturiente ou à un couple d’origine turque, ainsi qu'à son enfant, dans un service de post-natal ? Selon l’Office Fédéral de la Migration (OFM), en 2009, la Suisse comptait 7’874’088 habitants, dont 1’802’286 sont d’origine étrangère. La Suisse est un pays qui comporte un fort taux de population étrangère, il est donc évident qu’en tant que professionnels de la santé nous soyons amenés à soigner des personnes d’origines multiples chaque jour de notre vie professionnelle. La population turque représente 1 à 2% de la population suisse. De plus, la maternité est une valeur incontestable dans la pensée traditionnelle turque. Le couple ou la parturiente d'origine étrangère vivra l'accouchement et le postpartum selon ses propres références culturelles, ce qui peut créer des difficultés dans la prise en soins. Les problèmes principaux rencontrés par le personnel soignant face aux personnes d'origine étrangère se résument à des problèmes de communication, de différences culturelles, d'isolement et de précarité. Les soignants en maternité ont un rôle important à jouer afin de permettre l'accueil optimal de l'enfant et le soutien de la mère. Il est donc important que les parturientes d’origine étrangère soient entendues et prises en soins de manière holistique. De même, les infirmières ont besoin de se sentir soutenues dans leur travail au quotidien. Nous avons sélectionné huit articles scientifiques provenant de différents pays. Les points de vue diffèrent (perspectives des soignants ou recherches partant des patientes), mais nous conduisent à des résultats convergents. Notre sélection regroupe des recherches allant de 2002 à 2010. La Suisse est un pays sensibilisé à la question de l'interculturalité et la recherche à ce sujet dans le contexte de la maternité est assez développée. Cependant, il reste encore aux professionnels d'intégrer les concepts théoriques pour améliorer la prise en soins des couples et des parturientes d'origine étrangère.

description: L'objectif de ce travail est d'explorer et comprendre, par le biais d'articles scientifiques de recherches infirmières, les bonnes pratiques relationnelles permettant de créer et d'optimiser le lien entre l'infirmière, l'enfant et ses parents. Le contexte des soins "répétés et/ou de longue durée" est lié à notre désir d'appréhender la relation lorsque l'enfant est hospitalisé souvent ou durant un certain temps. Cette exploration a fait émerger quatre catégories dans lesquelles il est possible de regrouper les meilleures pratiques infirmières en terme de soins relationnels issues des articles de recherche choisis. Ces catégories sont : la dédramatisation, l'individualisation, la sécurité et le partenariat. Ce travail a conduit aux conclusions suivantes : - mise en évidence de compétences infirmières adaptées aux soins pédiatriques, aux besoins de l'enfant en terme de développement ainsi qu'aux attentes des parents - compréhension de ce que peuvent vivre les familles durant une période d'hospitalisation - émergence de l'impact du soin chronique ou de longue durée sur la relation soignant-soigné de manière générale - découverte du modèle centré sur les soins à la famille qui permet, grâce à un partenariat entre experts, de prodiguer des soins de haute qualité à l'enfant et à sa famille.

description: We present a path-integral bosonization approach for systems out of equilibrium based on a duality transformation of the original Dirac fermion theory combined with the Schwinger-Keldysh time closed contour technique, to handle the non-equilibrium situation. The duality approach to bosonization that we present is valid for $D \geq 2$ space-time dimensions leading for $D=2$ to exact results. In this last case we present the bosonization rules for fermion currents, calculate current-current correlation functions and establish the connection between the fermionic and bosonic distribution functions in a generic, nonequilibrium situation.
