description: I(V) characteristics and their first derivatives of ScS and ScN-type (S-superconductor, c-constriction, N-normal metal) point-contacts (PCs) based on Ba{1-x}NaxFe2As2 ($x$=0.25 and 0.35) were studied. ScS-type PCs with S=Nb,Ta and Pb show Josephson-like resistively shunted I(V) curves with microwave induced Shapiro steps which satisfy relation 2eV=hw. The I_cR_N product (I_c-critical current, R_N-- normal state PC resistance) in these PCs is found to be up to 1.2mV. All this data with the observed dependence of the I_c on the microwave power of ScS PCs with Pb counterelectrode indicates the presence of the singlet s-wave type pairing in Ba(1-x)NaxFe2As2. From the dV/dI(V) curves of ScN-type PCs demonstrating Andreev-reflection like features, the superconducting gap ratio 2Δ/k_BT_c = 3.6 \pm 1 for the compound with x=0.35 was evaluated. Analysis of these dV/dI(V) at high biases V, that is well above Δ, testifies transition to the thermal regime in PCs with a voltage increase.

description: 2D van der Waals heterostructures (vdWH) can result in novel functionality that crucially depends on interfacial structure and disorder. Bubbles at the vdWH interface can modify the interfacial structure. We probe the dynamics of a bubble at the interface of a graphene-hBN vdWH by using it as the drumhead of a NEMS device because nanomechanical devices are exquisite sensors. For drums with different interfacial bubbles, we measure the evolution of the resonant frequency and spatial mode shape as a function of electrostatic pulling. We show that the hysteretic detachment of layers of vdWH is triggered by the growth of large bubbles. The bubble growth takes place due to the concentration of stress resembling the initiation of fracture. The small bubbles at the heterostructure interface do not result in delamination as they are smaller than a critical fracture length. We provide insight into frictional dynamics and interfacial fracture of vdWH.

description: We study point-like polarizable particles confined in a 1D very elongated trap within the evanescent field of an optical nano-fiber or nano-structure. When illuminated transversely by coherent light, collective light scattering into propagating fiber modes induces long range interactions and eventually crystallisation of the particles into regular order. We develop a simple and intuitive scattering-matrix based approach to study these long-range interactions by collective scattering and the resulting light-induced self-ordering. For few particles we derive explicit conditions for self-consistent stable ordering. In the purely dispersive limit with negligible back-scattering, we recover the prediction of an equidistant lattice as previously found for effective dipole-dipole interaction models. We generalize our model to experimentally more realistic configurations including backscattering, absorption and a directional scattering asymmetry. For larger particle ensembles the resulting self-consistent particle-field equations can be numerically solved to study the formation of long-range order and stability limits.

description: This work formally investigates the differential evolution indicators as a tool for ultrasonic tracking of elastic transformation and fracturing in randomly heterogeneous solids. Within the framework of periodic sensing, it is assumed that the background contains (i) a multiply connected set of viscoelastic, anisotropic, and piecewise homogeneous inclusions, and (ii) a union of possibly disjoint fractures and pores. The support, material properties, and interfacial condition of scatterers in (i) and (ii) are unknown, while elastic constants of the matrix are provided. The domain undergoes progressive variations of arbitrary chemo-mechanical origins such that its geometric configuration and elastic properties at future times are distinct. At every sensing step $t_\circ, t_1, \ldots,$ multi-modal incidents are generated by a set of boundary excitations, and the resulting scattered fields are captured over the observation surface. The test data are then used to construct a sequence of wavefront densities by solving the spectral scattering equation. The incident fields affiliated with distinct pairs of obtained wavefronts are analyzed over the stationary and evolving scatterers for a suit of geometric and elastic evolution scenarios entailing both interfacial and volumetric transformations. The main theorem establishes the invariance of pertinent incident fields at the loci of static fractures and inclusions between a given pair of time steps, while certifying variation of the same fields over the modified regions. These results furnish a basis for theoretical justification of differential evolution indicators for imaging in complex composites which, in turn, enable the exclusive tomography of evolution in a background endowed with many unknown features.

description: We present the results from a VLT/SINFONI and Keck/NIRSPEC near-infrared spectroscopic survey of 16 Lyman-alpha emitters (LAEs) at $z$ = 2.1 - 2.5 in the COSMOS and GOODS-N fields discovered from the HETDEX Pilot Survey. We detect rest-frame optical nebular lines (H$α$ and/or [OIII]$λ$5007) for 10 of the LAEs and measure physical properties, including the star formation rate (SFR), gas-phase metallicity, gas-mass fraction, and Ly$α$ velocity offset. We find that LAEs may lie below the mass-metallicity relation for continuum-selected star-forming galaxies at the same redshift. The LAEs all show velocity shifts of Ly$α$ relative to the systemic redshift ranging between +85 and +296 km s$^{-1}$ with a mean of +180 km s$^{-1}$. This value is smaller than measured for continuum-selected star-forming galaxies at similar redshifts. The Ly$α$ velocity offsets show a moderate correlation with the measured star formation rate (2.5$σ$), but no significant correlations are seen with the SFR surface density, specific SFR, stellar mass, or dynamical mass ($\lesssim$ 1.5$σ$). Exploring the role of dust, kinematics of the interstellar medium (ISM), and geometry on the escape of Ly$α$ photons, we find no signature of selective quenching of resonantly scattered Ly$α$ photons. However, we also find no evidence that a clumpy ISM is enhancing the Ly$α$ equivalent width. Our results suggest that the low metallicity in LAEs may be responsible for yielding an environment with a low neutral hydrogen column density as well as less dust, easing the escape of Ly$α$ photons over that in continuum-selected star-forming galaxies.

description: Objectifs de l'étude Le but de notre travail est d’avoir une vision de la violence vécue par les techniciens en radiologie médicale (TRM) en mettant en avant les différents types de violences subies, ainsi que de présenter leurs auteurs et les facteurs favorisant leur apparition. L'étude présente également les diverses stratégies mises en place par les TRM, ainsi que les structures et mesures préventives de l'établissement et/ou des services incriminés pour tenter de diminuer et gérer la violence. Méthodologie Des entretiens semi-directifs ont été effectués dans quatre services de radiodiagnostic d'hôpitaux publics. Deux TRM par site ont participés à l'étude de manière anonyme en étant informés des conditions de la recherche. Afin de disposer d'une certaine expérience en la matière, les participants devaient au minimum avoir 3 ans d'expérience professionnelle et au minimum une année d’activité dans le service afin d’avoir pu se familiariser avec les procédures existantes. Résultats Les TRM sont principalement agressés par des patients sous l'emprise de l'alcool et/ou de drogues, ainsi que par des personnes démentes ou anxieuses. Une attente prolongée ou une mauvaise prise en charge par le TRM peut aussi provoquer de l'agressivité chez le patient. N'importe quel TRM peut être victime de violence, mais il ressort que le fait d'être une femme, ou d’être jeune TRM peut être un facteur de risque supplémentaire. Pour gérer les patients violents, les TRM se doivent de rester calmes et de prôner le dialogue. Dans les cas plus difficiles, ils vont demander de l'aide ou quitter les lieux afin de se protéger. Un agent de sécurité est constamment présent dans les hôpitaux. En ce qui concerne la prise en charge du TRM après une agression, cela reste du domaine de l’abstrait, et seuls peu de TRM connaissent les démarches à entreprendre en pareil cas. Conclusion Les TRM confrontés à la violence ont besoin de structures de soutien qui ne sont malheureusement pas assez présentes selon eux. Il est difficile d’agir sur certains facteurs propre aux patients. Cependant le temps d’attente et la prise en charge peuvent être des points sur lesquels le TRM peut intervenir afin de limiter leur agressivité.

description: Quelle est l’expérience quotidienne du prendre soin pour le conjoint d’une personne atteinte de fibromyalgie ? Les proches aidants sont aujourd’hui des partenaires de soins indispensables au système de santé. Toutefois, le complexe et périlleux chemin du prendre soin est rarement dénué de conséquences néfastes, notamment au niveau de la santé. Malgré cela, les proches aidants sont souvent peu soutenus et encadrés, bien qu’il s’agisse d’un devoir infirmier que de prévenir ces conséquences et de fournir du soutien. La fibromyalgie, pathologie courante mais toutefois encore médicalement inexpliquée, est peu reconnue dans la société actuelle, et notamment dans le monde médical. Sa chronicité, sa pénibilité et son caractère invalidant ont pourtant des répercussions graves sur la personne atteinte et sur son entourage. Le but de ce travail était d’investiguer l’expérience quotidienne du prendre soin pour le conjoint d’une personne atteinte de fibromyalgie. Une brève revue de littérature a été réalisée sur les bases de données CINAHL et PubMed. Huit articles ont été sélectionnés puis analysés. Quatre thèmes principaux ont pu être dégagés de l’expérience du prendre soin et particulièrement de ses conséquences, à savoir : Risque d’altération de la santé, Manque de soutien et d’information, Perturbation de la dynamique de couple et Augmentation des responsabilités. Ces résultats ont permis de mettre en lumière le vécu des proches aidants et ainsi de guider la pratique infirmière avec le développement d’interventions pertinentes en regard de leurs besoins.

description: We present a numerical parametric study of single-cycle electromagnetic pulse generation in a DAST/SiO2 multilayer structure via collinear optical rectification of 800 nm femtosecond laser pulses. It is shown that modifications of the thicknesses of the DAST and SiO2 layers allow tuning of the average frequency of the generated THz pulses in the frequency range from 3 to 6 THz. The laser-to-THz energy conversion efficiency in the proposed structures is compared with that in a bulk DAST crystal and a quasi-phase-matching periodically poled DAST crystal and shows significant enhancement.

description: We present a new planetary global circulation model, planetMPAS, based on the state-of-the-art NCAR MPAS General Circulation Model. Taking advantage of the cross compatibility between WRF and MPAS, planetMPAS includes most of the planetWRF physics parameterization schemes for terrestrial planets such as Mars and Titan. PlanetMPAS also includes a set of physics that represents radiative transfer, dry convection, moist convection and its associated microphysics for the Jovian atmosphere. We demonstrate that, despite the rigid-lid approximation, planetMPAS is suitable to simulate the climate systems in Martian and Jovian atmospheres with potential application to slow-rotating planets such as Titan. Simulations using planetMPAS show that the new model can reproduce many aspects of the observed features on Mars and Jupiter, such as the seasonal CO2 cycle, polar argon enrichment, zonal mean temperature, and qualitative dust opacity on Mars, as well as the equatorial superrotation and banded zonal wind patterns on Jupiter.

description: We construct and analyze holographic superconductors with generalized higher derivative couplings, in single R-charged black hole backgrounds in four and five dimensions. These systems, which we call very general holographic superconductors, have multiple tuning parameters and are shown to exhibit a rich phase structure. We establish the phase diagram numerically as well as by computing the free energy, and then validated the results by calculating the entanglement entropy for these systems. The entanglement entropy is shown to be a perfect indicator of the phase diagram. The differences in the nature of the entanglement entropy in R-charged backgrounds compared to the AdS-Schwarzschild cases are pointed out. We also compute the analogue of the entangling temperature for a subclass of these systems and compare the results with non-hairy backgrounds.

L’image corporelle et le rapport au corps sont des éléments à risque d’être perturbés chez ces jeunes filles, c’est pourquoi des interventions infirmières en lien avec ces composantes sont importantes dans l’accompagnement de ces dernières. Objectif Trouver des interventions infirmières en lien avec l’image corporelle, afin de favoriser la guérison et d’éviter les rechutes chez des adolescentes atteintes d’anorexie. Méthode Les bases de données CINHAL et PubMed utilisées nous ont fourni huit articles pertinents. Résultats Trois thèmes ressortent de nos résultats : l’estime de soi, la perception corporelle et les interventions infirmières. Les articles étudiés montrent que durant l’adolescence, l’estime de soi est liée à la perception que l’on a de soi. Concernant cette perception, il n’y aurait pas de distorsion de la perception corporelle chez ces patientes. Concernant la prise en charge, le soutien des infirmières et des groupes de pairs est déterminant dans la guérison. Conclusion D’autres recherches devraient être effectuées concernant la prise en charge infirmière en lien avec l’image corporelle pour des patientes anorexiques, afin d’avoir des propositions d’actions concrètes qui permettraient d’améliorer leur image corporelle. La dimension sociale de l’anorexie est peu prise en compte et devrait être plus abordée. Il n’y a pas de recherches longitudinales, ce qui limite la crédibilité des résultats.

description: Explanatory Interactive Learning (XIL) collects user feedback on visual model explanations to implement a Human-in-the-Loop (HITL) based interactive learning scenario. Different user feedback types will have different impacts on user experience and the cost associated with collecting feedback since different feedback types involve different levels of image annotation. Although XIL has been used to improve classification performance in multiple domains, the impact of different user feedback types on model performance and explanation accuracy is not well studied. To guide future XIL work we compare the effectiveness of two different user feedback types in image classification tasks: (1) instructing an algorithm to ignore certain spurious image features, and (2) instructing an algorithm to focus on certain valid image features. We use explanations from a Gradient-weighted Class Activation Mapping (GradCAM) based XIL model to support both feedback types. We show that identifying and annotating spurious image features that a model finds salient results in superior classification and explanation accuracy than user feedback that tells a model to focus on valid image features.

description: Both long and short gamma-ray bursts (GRBs) are expected to occur in the dense environments of active galactic nuclei (AGN) accretion disks. As these bursts propagate through the disks they live in, they photoionize the medium causing time-dependent opacity that results in transients with unique spectral evolution. In this paper we use a line-of-sight radiation transfer code coupling metal and dust evolution to simulate the time-dependent absorption that occurs in the case of both long and short GRBs. Through these simulations, we investigate the parameter space in which dense environments leave a potentially observable imprint on the bursts. Our numerical investigation reveals that time dependent spectral evolution is expected for central supermassive black hole masses between $10^5$ and $5 \times 10^7$ solar masses in the case of long GRBs, and between $10^4$ and $10^7$ solar masses in the case of short GRBs. Our findings can lead to the identification of bursts exploding in AGN disk environments through their unique spectral evolution coupled with a central location. In addition, the study of the time-dependent evolution would allow for studying the disk structure, once the identification with an AGN has been established. Finally, our findings lead to insight into whether GRBs contribute to the AGN emission, and which kind, thus helping to answer the question of whether GRBs can be the cause of some of the as-of-yet unexplained AGN time variability.

Ce travail s’intéresse particulièrement à l’image corporelle des personnes amputées. Objectifs : Identifier les interventions infirmières lors du processus d’ajustement des patients atteints dans leur image corporelle. Méthode : Une recension des écrits à partir de recherches scientifiques Medline et CINHAL a été effectuée. Huit articles scientifiques en anglais publiés entre 2004 et 2013 qui ciblent le vécu et les perceptions des personnes traversant un ajustement ont été retenus. Résultats : Les résultats émergeant des différentes revues de littératures sont regroupés en trois catégories principales : la souffrance, les perspectives d’avenir et les ressources. La première englobe le deuil, la culpabilité, la baisse de l’estime de soi, l’image corporelle et la souffrance physique. Dans la perspective d’avenir, la question de la profession suite à une amputation est relevée ainsi que les soins futurs et la vie intime et relationnelle. La dernière catégorie développe les ressources et traite du soutien des pairs, du programme de réhabilitation et de la pensée positive (coping). Ces différentes thématiques font émerger des domaines d’intervention pour l’infirmière auprès des patients touchés dans leur image corporelle. Une partie des interventions provient des revues scientifiques et une autre s’inspire de nos propositions personnelles, de la théorie à large spectre de Callista Roy et de la NANDA.

Le traitement médicamenteux de la schizophrénie consiste en la prescription d’antipsychotiques. Il est constaté que de nombreux patients ne sont pas adhérents à ces médicaments. Or, cette non-adhérence est l’une des causes pouvant amener à des rechutes et à des réhospitalisations du patient et donc à une baisse de la qualité de vie. Ce travail traite des interventions infirmières qui visent à améliorer l’adhérence aux antipsychotiques chez les personnes souffrant de schizophrénie. Le cadre théorique de Cheryl Cox permet d’appuyer l’importance de la relation patientsoignant et la prise en considération des caractéristiques propres au patient ayant une influence sur les résultats de santé. Méthode : une recension narrative à partie des bases de données CINHAL et Pub Med a permis de sélectionner 10 articles. Résultats : Les résultats exposent différentes interventions spécifiques fournies par des infirmières en santé mentale. Elles comprennent l’éducation à la famille et au patient, des thérapies de type motivationnel et/ou cognitivo-comportemental, orientée sur le système de soins ou basées sur des appels téléphoniques. Cinq se sont révélées probantes. Conclusions : La relation qu’implique la mise en place de ces interventions est influencée par les caractéristiques des patients.

ENVIRONMENTAL COMPONENTS OF AGRICULTURAL SUPPORT POLICY: HOW DOES CANADA COMPARE WITH OTHER OECD MEMBERS?
Creators: Maureira, Renato
Publisher: name: University of Alberta Library
Year: 2021

As an avid consumer of natural resources, agriculture is a major source of environmental harm, but it is also seen as a potential contributor to its mitigation, indicating that environmental measures on agriculture could have positive impacts. In this work we categorize the environmental components of agricultural policies reported by each country to the OECD’s Producer Support Estimate database and develop variables that calculate five ratios that are used to compare the measures for Canada and three other developed OECD countries. The results show that the performance of Canada is lower than expected given its commitments to action in the international scene, and that there is a lot to be done from an agricultural policy perspective to protect the environment and mitigate the impacts of agricultural activity.

description: We study the performance of a stochastic algorithm based on the power method that adaptively learns the large deviation functions characterizing the fluctuations of additive functionals of Markov processes, used in physics to model nonequilibrium systems. This algorithm was introduced in the context of risk-sensitive control of Markov chains and was recently adapted to diffusions evolving continuously in time. Here we provide an in-depth study of the convergence of this algorithm close to dynamical phase transitions, exploring the speed of convergence as a function of the learning rate and the effect of including transfer learning. We use as a test example the mean degree of a random walk on an Erdös-Rényi random graph, which shows a transition between high-degree trajectories of the random walk evolving in the bulk of the graph and low-degree trajectories evolving in dangling edges of the graph. The results show that the adaptive power method is efficient close to dynamical phase transitions, while having many advantages in terms of performance and complexity compared to other algorithms used to compute large deviation functions.

Subjects: subject: Chaotic Dynamics (nlin.CD)

description: The spectral form factor as well as the two-point correlator of the density of (quasi-)energy levels of individual quantum dynamics are not self-averaging. Only suitable smoothing turns them into useful characteristics of spectra. We present numerical data for a fully chaotic kicked top, employing two types of smoothing: one involves primitives of the spectral correlator, the second a small imaginary part of the quasi-energy. Self-averaging universal (like the CUE average) behavior is found for the smoothed correlator, apart from noise which shrinks like $1\over\sqrt N$ as the dimension $N$ of the quantum Hilbert space grows. There are periodically repeated quasi-energy windows of correlation decay and revival wherein the smoothed correlation remains finite as $N\to\infty$ such that the noise is negligible. In between those windows (where the CUE averaged correlator takes on values of the order ${1\over N^2}$) the noise becomes dominant and self-averaging is lost. We conclude that the noise forbids distinction of CUE and GUE type behavior. Surprisingly, the underlying smoothed generating function does not enjoy any self-averaging outside the range of its variables relevant for determining the two-point correlator (and certain higher-order ones). --- We corroborate our numerical findings for the noise by analytically determining the CUE variance of the smoothed single-matrix correlator.

description: Controlled-release fertilizers (CRFs) are sustainable alter-natives as they can increase crop yield and minimize environmental contamination associated with conventional fertilizers. However, there remains a demand for the development of CRFs with high biocompatibility, and tunable morphologies and mechanical properties. Herein, a solvent-free mechanochemical method is developed for synthesizing urea-encapsulated metal−phenolic networks (urea−MPN matrices) as CRFs. The matrices exhibit tunable mechanical resistance, crystallinity, stiffness, and wettability properties via rearranging the internal structure of the MPNs and their subsequent interaction with the encapsulated urea crystals. Sample aging (7 days) leads to a higher degree of complexation of the MPNs, resulting in a material with increased elasticity and melting point relative to the as-synthesized sample. Thermal treatment (60 °C for 6 h) instigates structural reorganization of the urea crystals within the matrix, generating a more robust material with a 51-fold increase in Young’s modulus. As CRFs, the urea−MPN matrices can be tuned to prolong the release of urea for up to 9 days depending on the treatment applied. As the mechanochemical synthesis of MPNs facilitates the tuning of physiochemical properties and has greater practicability for inclusion within large-scale processing, it has potential implementation within a broad range of industries.

description: The merit of projecting data onto linear subspaces is well known from, e.g., dimension reduction. One key aspect of subspace projections, the maximum preservation of variance (principal component analysis), has been thoroughly researched and the effect of random linear projections on measures such as intrinsic dimensionality still is an ongoing effort. In this paper, we investigate the less explored depths of linear projections onto explicit subspaces of varying dimensionality and the expectations of variance that ensue. The result is a new family of bounds for Euclidean distances and inner products. We showcase the quality of these bounds as well as investigate the intimate relation to intrinsic dimensionality estimation.

description: Interplanetary scintillation (IPS) is a useful tool for detecting coronal mass ejections (CMEs) throughout interplanetary space. Global magnetohydrodynamic (MHD) simulations of the heliosphere, which are usually used to predict the arrival and geo-effectiveness of CMEs, can be improved using IPS data. In this study, we demonstrate an MHD simulation that includes IPS data from multiple stations to improve CME modelling. The CMEs, which occurred on 09-10 September 2017, were observed over the period 10-12 September 2017 using the Low-Frequency Array (LOFAR) and IPS array of the Institute for Space-Earth Environmental Research (ISEE), Nagoya University, as they tracked through the inner heliosphere. We simulated CME propagation using a global MHD simulation, SUSANOO-CME, in which CMEs were modeled as spheromaks, and the IPS data were synthesised from the simulation results. The MHD simulation suggests that the CMEs merged in interplanetary space, forming complicated IPS g-level distributions in the sky map. We found that the MHD simulation that best fits both LOFAR and ISEE data provided a better reconstruction of the CMEs and a better forecast of their arrival at Earth than from measurements when these simulations were fit from the ISEE site alone. More IPS data observed from multiple stations at different local times in this study can help reconstruct the global structure of the CME, thus improving and evaluating the CME modelling.

description: We investigate the properties of 367 ultra-short period binary candidates selected from 31,000 sources recently identified from Catalina Surveys data. Based on light curve morphology, along with WISE, SDSS and GALEX multi-colour photometry, we identify two distinct groups of binaries with periods below the 0.22 day contact binary minimum. In contrast to most recent work, we spectroscopically confirm the existence of M-dwarf+M-dwarf contact binary systems. By measuring the radial velocity variations for five of the shortest-period systems, we find examples of rare cool-white dwarf+M-dwarf binaries. Only a few such systems are currently known. Unlike warmer white dwarf systems, their UV flux and their optical colours and spectra are dominated by the M-dwarf companion. We contrast our discoveries with previous photometrically-selected ultra-short period contact binary candidates, and highlight the ongoing need for confirmation using spectra and associated radial velocity measurements. Overall, our analysis increases the number of ultra-short period contact binary candidates by more than an order of magnitude.

description: We present ALMA dust polarization and molecular line observations toward 4 clumps (I(N), I, IV, and V) in the massive star-forming region NGC 6334. In conjunction with large-scale dust polarization and molecular line data from JCMT, Planck, and NANTEN2, we make a synergistic analysis of relative orientations between magnetic fields ($θ_{\mathrm{B}}$), column density gradients ($θ_{\mathrm{NG}}$), local gravity ($θ_{\mathrm{LG}}$), and velocity gradients ($θ_{\mathrm{VG}}$) to investigate the multi-scale (from $\sim$30 pc to 0.003 pc) physical properties in NGC 6334. We find that the relative orientation between $θ_{\mathrm{B}}$ and $θ_{\mathrm{NG}}$ changes from statistically more perpendicular to parallel as column density ($N_{\mathrm{H_2}}$) increases, which is a signature of trans-to-sub-Alfvénic turbulence at complex/cloud scales as revealed by previous numerical studies. Because $θ_{\mathrm{NG}}$ and $θ_{\mathrm{LG}}$ are preferentially aligned within the NGC 6334 cloud, we suggest that the more parallel alignment between $θ_{\mathrm{B}}$ and $θ_{\mathrm{NG}}$ at higher $N_{\mathrm{H_2}}$ is because the magnetic field line is dragged by gravity. At even higher $N_{\mathrm{H_2}}$, the angle between $θ_{\mathrm{B}}$ and $θ_{\mathrm{NG}}$ or $θ_{\mathrm{LG}}$ transits back to having no preferred orientation or statistically slightly more perpendicular, suggesting that the magnetic field structure is impacted by star formation activities. A statistically more perpendicular alignment is found between $θ_{\mathrm{B}}$ and $θ_{\mathrm{VG}}$ throughout our studied $N_{\mathrm{H_2}}$ range, which indicates a trans-to-sub-Alfvénic state at small scales as well. The normalised mass-to-flux ratio derived from the polarization-intensity gradient (KTH) method increases with $N_{\mathrm{H_2}}$.

description: LiteBIRD is a space-borne experiment dedicated to detecting large-scale $B$-mode anisotropies in the linear polarization of the Cosmic Microwave Background (CMB) predicted by the theory of inflation. It is planned to be launched in the late 2020s to the second Lagrange point (L2) of the Sun-Earth system. LiteBIRD will map the sky in 15 frequency bands. In comparison to $\it{Planck}$ HFI, the previous low-temperature bolometer-based satellite for CMB observations, the number of detector has increased by two orders of magnitude, up to $\sim$5000 detectors in total. The data rate is 19 Hz from each detector. The bandpass to the ground is limited to 10 Mbps using the X-band for a few hours per day. These require the data to be compressed by more than 50 %. The exact value depends on how much information entropy is contained in the real data. We have thus evaluated the compression by simulating the time-ordered data of polarization sensitive bolometers. The foreground emission, detector noise, cosmic ray glitches, leakage from the CMB intensity to polarization, etc. are simulated. We investigated several algorithms and demonstrated that the required compression ratio can be achieved by some of them. We describe the details of this evaluation and propose algorithms that can be employed in the on-board digital electronics of LiteBIRD.

description: Problématique : La fatigue est l’un des effets secondaires consécutif de la chimiothérapie qui peut affecter les dimensions psychologique, physique, sociale, spirituelle et avoir un impact sur la qualité de vie des femmes actives. Elle est sous-estimée aussi bien par les professionnels de la santé que par les patientes. De plus, l’expression de la fatigue chez les patientes reste à bas bruit, voire silencieuse. But : Rechercher les accompagnements thérapeutiques infirmiers permettant aux patientes de 30 à 65 ans atteintes d’un cancer du sein de gérer la fatigue consécutive à la chimiothérapie. Méthode : Une revue littérature a été effectuée sur les bases de données CINHAL, PubMed et sur Google Scholar. Huit articles ont été sélectionnés et analysés. Résultats : Cette revue démontre que la fatigue est souvent associée à d’autres symptômes (troubles du sommeil, affaiblissement psychologique) et a un impact non-négligeable sur les activités sociales et professionnelles de la personne. La compréhension de l'expérience des patientes dans leur contexte est essentielle pour l'élaboration des interventions infirmières. Il existe des méthodes complémentaires, exercices physiques et relaxation musculaireefficaces et accessibles pour la gestion de la fatigue. Conclusion : Le rôle infirmier est d’informer les patientes sur la fatigue, de ne pas sous-estimer ce symptôme, de l’évaluer systématiquement, de chercher des moyens, des ressources extérieures, d’amener le sujet auprès de l’équipe pluridisciplinaire. Des méthodes concrètes de diminution de la fatigue restent à explorer.
