Published: April 2023

Emergency department overcrowding was a obstacle of providing timely and effective care in emergency department. This condition had negatively impact on many aspect of care proccess. There were different finding related to impact of emergency department overcrowding in care process. The aim of the study was to analyze research articles that discusses emergency department overcrowding and its potential impact on care proccess. The study was literature review using database journal resources from PubMed, Proquest, and ScienceDirect. Emergency department (ED), Overcrowding, and impact we used as keyword. Inclusion criteria of the study were original article, Published at 10 years later (2012-2022), written in english language, focus on patient, staff, or health care system level. Whereas, the exclusion criteria were overcrowding because of other condition (endemic or infection disease), and not focus on patient, staff, or health care system. 9 selected articles that met inclusion criteria were analysed based on author, years, title, and main idea of the study. The finding of the study were emergency department overcrowding had negatively impact on care process including patients, staff, and healthcare system. Impact on patients including increasing mortality and admission rate, impact on staff including increasing workload and non-adherence for practicing best guidelines, meanwhile impact on healthcare system including innapropriate triage proccess and increasing Length of Stay (LOS). Need an effort to decrease impact of ED overcrowding especially on patient, staff, and healthcare system. The result of the study could be used as considering to formulate an effort to reduce impact of ED overcrowding by controlling patient, staff, and healthcare system factors.
Tight Bound for the Number of Distinct Palindromes in a Tree
Authors: Gawrychowski Paweł , Kociumaka Tomasz , Rytter Wojciech , Waleń Tomasz 
Published: April 2023

For an undirected tree with edges labeled by single letters, we consider its substrings, which are labels of the simple paths between two nodes. A palindrome is a word $w$ equal to its reverse $w^R$. We prove that the maximum number of distinct palindromic substrings in a tree of $n$ edges satisfies $\text{pal}(n)=O(n^{1.5})$. This solves an open problem of Brlek, Lafrenière, and Provençal (DLT 2015), who showed that $\text{pal}(n)=\Omega(n^{1.5})$. Hence, we settle the tight bound of $\Theta(n^{1.5})$ for the maximum palindromic complexity of trees. For standard strings, i.e., for trees that are simple paths, the maximum palindromic complexity is exactly $n+1$.
We also propose an $O(n^{1.5} \log^{0.5}{n})$-time algorithm reporting all distinct palindromes and an $O(n \log^2 n)$-time algorithm finding the longest palindrome in a tree.

Abstract
The transmission spectrum of the ultrahot Jupiter KELT-9b (T
eq ∼ 4000 K) exhibits absorption by several metal species. We searched for atomic and molecular lines in its emission spectrum by observing partial phase curves with the Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs (R ∼ 80,000–95,000). We find evidence for emission by Si i in the atmosphere of KELT-9b for the first time. Additionally we find evidence for emission by Mg i and Ca ii, which were previously detected in transmission, and confirmed earlier detections of Fe i emission. Conversely, we find no evidence for dayside emission from Al i, Ca i, Cr i, FeH, Fe ii, K i, Li i, Mg ii, Na i, OH, Ti i, TiO, V i, V ii, VO, and Y i. By employing likelihood mapping, we find indications of there being little variation in emission line contrast between the day- and nightsides—suggesting that KELT-9b may harbor iron emission on its nightside. Our results demonstrate that high-resolution ground-based emission spectroscopy can provide valuable insights into exoplanet atmospheres.
Magnetohydrodynamic Turbulence Formation in Solar Flares: 3D Simulation and Synthetic Observations
Authors: Ruan W. , Yan L. , Keppens R. 
Published: April 2023

Abstract
Turbulent plasma motion is common in the universe and invoked in solar flares to drive effective acceleration leading to high-energy electrons. Unresolved mass motions are frequently detected in flares from extreme ultraviolet (EUV) observations, which are often regarded as turbulence. However, how this plasma turbulence forms during the flare is still largely a mystery. Here we successfully reproduce observed turbulence in our 3D magnetohydrodynamic simulation where the magnetic reconnection process is included. The turbulence forms as a result of an intricate nonlinear interaction between the reconnection outflows and the magnetic arcades below the reconnection site, in which the shear-flow-driven Kelvin–Helmholtz instability (KHI) plays a key role in generating turbulent vortices. The turbulence is produced above high-density flare loops and then propagates to chromospheric footpoints along the magnetic field as Alfvénic perturbations. High turbulent velocities above 200 km s−1 can be found around the termination shock, while the low atmosphere reaches turbulent velocities of 10 km s−1 at a layer where the number density is about 1011 cm−3. The turbulent region with maximum nonthermal velocity coincides with the region where the observed high-energy electrons are concentrated, demonstrating the potential role of turbulence in acceleration. Synthetic views in EUV and fitted Hinode-EUV Imaging Spectrometer spectra show excellent agreement with observational results. An energy analysis demonstrates that more than 10% of the reconnection-downflow kinetic energy can be converted to turbulent energy via KHI.

Published: April 2023

Abstract
We describe pynucastro 2.0, an open-source library for interactively creating and exploring astrophysical nuclear reaction networks. We demonstrate new methods for approximating rates and use detailed balance to create reverse rates, show how to build networks and determine whether they are appropriate for a particular science application, and discuss the changes made to the library over the past few years. Finally, we demonstrate the validity of the networks produced and share how we use pynucastro networks in simulation codes.

Abstract
We present the first results from a 100-day Swift, NICER, and ground-based X-ray–UV–optical reverberation mapping campaign of the Narrow-line Seyfert 1 Mrk 335, when it was in an unprecedented low X-ray flux state. Despite dramatic suppression of the X-ray variability, we still observe UV–optical lags as expected from disk reverberation. Moreover, the UV–optical lags are consistent with archival observations when the X-ray luminosity was >10 times higher. Interestingly, both low- and high-flux states reveal UV–optical lags that are 6–11 times longer than expected from a thin disk. These long lags are often interpreted as due to contamination from the broad line region; however the u-band excess lag (containing the Balmer jump from the diffuse continuum) is less prevalent than in other active galactic nuclei. The Swift campaign showed a low X-ray-to-optical correlation (similar to previous campaigns), but NICER and ground-based monitoring continued for another 2 weeks, during which the optical rose to the highest level of the campaign, followed ∼10 days later by a sharp rise in X-rays. While the low X-ray countrate and relatively large systematic uncertainties in the NICER background make this measurement challenging, if the optical does lead X-rays in this flare, this indicates a departure from the zeroth-order reprocessing picture. If the optical flare is due to an increase in mass accretion rate, this occurs on much shorter than the viscous timescale. Alternatively, the optical could be responding to an intrinsic rise in X-rays that is initially hidden from our line of sight.
Kinematic Evidence of an Embedded Protoplanet in HD 142666 Identified by Machine Learning

Published: April 2023

Abstract
Observations of protoplanetary disks have shown that forming exoplanets leave characteristic imprints on the gas and dust of the disk. In the gas, these forming exoplanets cause deviations from Keplerian motion, which can be detected through molecular line observations. Our previous work has shown that machine learning can correctly determine if a planet is present in these disks. Using our machine-learning models, we identify strong, localized non-Keplerian motion within the disk HD 142666. Subsequent hydrodynamics simulations of a system with a 5 M
J planet at 75 au recreate the kinematic structure. By currently established standards in the field, we conclude that HD 142666 hosts a planet. This work represents a first step toward using machine learning to identify previously overlooked non-Keplerian features in protoplanetary disks.

The design of new materials intended for operation under severe conditions faces the task of rendering the materials corrosion resistant. The practical solution of this task is interrelated with the knowledge of corrosion protection of metals and alloys. The use of conducting aluminum alloys for the manufacture of thin wire may encounter specific problems. This is caused by the insufficient strength of these alloys and a small number of kinks before fracture. Aluminum alloys have been developed in recent years which even in a soft state have strength characteristics that allow them to be used as a conductive material. The E-AlMgSi (Aldrey) aluminum alloy is a well-known conducting alloy. This alloy is a heat-strengthened one, possessing good plasticity and high strength. After appropriate heat treatment this alloy acquires high electrical conductivity. Wires made from this alloy are almost exclusively used for air transmission lines.
This work presents data on the corrosion behavior of calcium containing E-AlMgSi (Aldrey) aluminum conducting alloy in 0.03, 0.3 and 3.0% NaCl electrolyte medium. The anodic behavior of the alloy has been studied using a potentiostatic technique with a PI-50-1.1 potentiostat at a 2 mV/s potential sweep rate. Calcium doping of the E-AlMgSi (Aldrey) aluminum alloy increases its corrosion resistance by 15–20%. The corrosion, pitting and repassivation potentials of calcium doped alloys shift toward the positive region. An increase in the sodium chloride electrolyte concentration leads to a decrease in these potentials.

ObjectiveAxial spondyloarthritis (axSpA) is associated with decreased function and mobility of patients as a result of inflammation and radiographic damage. The Epionics SPINE device (ES), an electronic device that objectively measures spinal mobility, including range of motion (RoM) and speed (ie, range of kinematics [RoK]) of movement, has been clinically validated in axSpA. We investigated the performance of the ES relative to radiographic damage in the axial skeleton of patients with axSpA.MethodsA total of 103 patients with axSpA, 31 with nonradiographic axSpA (nr-axSpA) and 72 with radiographic axSpA (r-axSpA), were consecutively examined. Conventional radiographs of the spine (including presence, number, and location of syndesmophytes) and the sacroiliac joints (SIJs; rated by the modified New York criteria) were analyzed with the ES. Function and mobility were assessed using analyses of covariance and Spearman correlation.ResultsThe number of syndesmophytes correlated positively with Bath Ankylosing Spondylitis Metrology Index scores (r0.38,P= 0.02) and correlated negatively with chest expansion (r−0.39,P= 0.02) and ES measurements (−0.53 ≤r≤ −0.34, allP< 0.03), except for RoM and RoK regarding rotation and RoK for extension of the lumbar and thoracic spines. In the radiographic evaluation of the SIJs, the extent of damage correlated negatively with ES scores and metric measurements (−0.49 ≤r≤ −0.33, allP< 0.001). Patients with r-axSpA, as compared to those with nr-axSpA, showed significantly worse ES scores for RoM, RoK, and chest expansion.ConclusionThe ES scores, in accordance with mobility measurements, correlated well with the presence and extent of radiographic damage in the spine and the SIJs. As expected, patients with r-axSpA had more severe impairments than those with nr-axSpA.

Published: April 2023

ObjectiveCalcium pyrophosphate deposition (CPPD) disease prevalence is similar to that of gout and osteoarthritis (OA), yet CPPD outcomes research greatly lags behind research in these other forms of arthritis. We compared validated patient-reported outcome measures in patients with CPPD vs gout and OA.MethodsPatients with CPPD were recruited from Brigham and Women’s Hospital from 2018 to 2022. Presence of CPPD manifestations (acute calcium pyrophosphate [CPP] crystal arthritis, chronic CPP inflammatory arthritis, and/or OA with CPPD) was confirmed by medical record review. Baseline surveys included the Gout Assessment Questionnaire version 2.0, modified to ask about “pseudogout” rather than “gout”; Routine Assessment of Patient Index Data 3 (RAPID-3); and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). We compared responses in patients with CPPD against published gout and OA cohort studies.ResultsAmong 47 patients with CPPD, the mean age was 71.9 years and 51% were female. Sixty-eight percent had at least 1 episode of acute CPP crystal arthritis, 40% had chronic CPP inflammatory arthritis, and 62% had OA with CPPD. Pain visual analog scale scores during a flare were similar in CPPD (mean 6.8 [SD 1.9]) and gout (mean 6.7 [SD 2.6];P= 0.78). Patients with CPPD reported significantly greater unmet treatment need than patients with gout (P= 0.04). RAPID-3 scores in CPPD (mean 8.1 [SD 5.6]) were lower than in gout (mean 12.1 [SD 6.2];P< 0.01) and similar in OA (mean 6.8 [SD 6.1];P= 0.30). Patients with CPPD had significantly worse WOMAC stiffness scores than patients with mild OA, and significantly better WOMAC function scores than patients with severe OA.ConclusionPatients with CPPD may experience pain comparable to that in gout and OA and reported substantial unmet treatment needs.
La voie du socialisme écologique
Authors: Bet Marion , Carenini Emma , Cazeneuve Nathan , Phatthanasinh Emmanuel 
Published: April 2023

La « question écologique » n’a pas remplacé la « question sociale » : elle la reformule et la complexifie en intégrant à la compréhension des interdépendances sociales leurs conditions environnementales. Le socialisme constitue ainsi la matrice politique la plus pertinente pour penser les liens entre solidarités sociales et environnementales. Le réalisme écologique implique donc une politique sociale vigoureuse de solidarité fondée sur le travail et la réduction des inégalités, autant de conditions nécessaires à la réalisation d’une véritable transformation écologique.
« Nous prenons aux animaux sans plus rien leur rendre »

Face à la logique industrielle de la production animale fondée sur l’exploitation, Jocelyne Porcher, éleveuse, ingénieure agronome, et sociologue, rappelle que l’élevage paysan consiste en une relation de coopération par le travail entre l’animal et l’éleveur. Loin des théories de la libération animale qui voient dans toute forme d’élevage une exploitation des animaux et de l’approche utilitariste fondée sur le seul « bien-être animal », Jocelyne Porcher nous invite à prendre au sérieux la rationalité relationnelle qui fonde la coopération caractéristique de l’élevage paysan.

Face aux limites du féminisme « décolonial » et « intersectionnel » qui condamne le discours d’un féminisme supposément « blanc » et vecteur d’oppression, et aux attaques du discours féministes contemporain par la droite conservatrice et identitaire, il est essentiel de prendre au sérieux la portée universelle et émancipatrice du discours féministe, à condition que ses formulations demeurent concrètes et fassent droit au pluralisme des revendications.
Des objets-cadres à la double polarité – différenciée et non différenciée – des liens
Authors: Matot Jean-Paul 
Published: April 2023

Dans un article pionnier, D. Flagey repère, dans certaines analyses de patients ayant connu des défaillances graves dans leurs premières relations, la fonction des « objets-cadres », héritiers de la « mère-environnement » de Winnicott. Ces objets-cadres passent le plus souvent inaperçus, leur fonction étant reprise par ce qu’elle qualifie comme « l’écosystème » de l’individu. Flagey ouvre ainsi le champ du psychisme non objectal, non différencié, non pulsionnel, qui constitue pour moi le fondement du sentiment d’exister. Quelques années plus tard, J. Godfrind reprend cette réflexion à partir de l’investissement particulier que font certains patients du cadre matériel du bureau de l’analyste. Sa réflexion s’appuie notamment sur les travaux de Searles sur « l’apparentement » à « l’environnement non humain ». Ces travaux remarquables, peu développés par la suite dans les réflexions psychanalytiques, invitent pourtant à remettre au travail certains paradigmes fondateurs de la psychanalyse freudienne, comme l’impensé de la « réalité externe », l’omniprésence de « l’objet », l’illusion portée par le concept de « Moi » ou de « sujet ». L’article de Godfrind en particulier pose les bases d’une dynamique tiercéisante entre le champ différencié, investi par la pulsion, et le champ non différencié, relevant de l’informe. Cette dynamique oscillatoire permet d’aborder autrement les problématiques mettant en jeu des processus de dé-différenciation, par exemple dans la passion et la mélancolie.
De la séduction numérique
Authors: Minotte Pascal , Matot Jean-Paul 
Published: April 2023

De la séduction numérique La séduction exercée par les technologies numériques fait intervenir une dimension magique qui satisfait – dans une certaine mesure – une illusion omnipotente. Elles estompent les limites entre communication sociale, jeu, information et aménagements identitaires, et occupent pour l’humain connecté une fonction prothétique qui fait communiquer des niveaux de réalités hétérogènes. La perception du temps et de l’espace se trouve modifiée, avec des vécus d’ubiquité, de simultanéité, d’accélération, mais surtout d’immersion, dont le négatif est les sentiments d’épuisement, de débordement, d’impuissance. Les auteurs abordent plus particulièrement les jeux vidéo comme analyseurs des évolutions de la séduction consumériste numérique. Ils décrivent l’évolution des modèles économiques et des techniques de cette industrie, le jeu gratuit devenant un attracteur dont la rentabilité financière repose sur l’achat de services supplémentaires augmentant le plaisir des joueurs, et intervenant dans la reconnaissance au sein des communautés de joueurs. Sur le plan de l’économie psychique, certains jeux vidéo offrent un contenant aux tensions internes, leur fil narratif apportant une dimension de symbolisation. Les réseaux sociaux, de leur côté, ont une fonction d’extension de l’espace intime vers un espace social virtuel partagé, installant une communication entre des enveloppes psychiques habituellement distinctes. Cette dimension peut entraîner une confusion des espaces psychiques, avec des effets traumatiques de « désintimité ». Une autre dimension de la séduction numérique réside dans le sentiment d’« existence » que peut donner l’appartenance à des « communautés » numériques, et dans l’autoconfirmation que procurent les algorithmes qui déterminent la sélection des informations et des offres « socialisantes » des réseaux. L’autre face de ces processus commerciaux est celle de « l’ombre numérique », cette identité masquée construite par les recueils de données des utilisateurs, « matière première » exploitée par les propriétaires des platesformes numériques. Enfin, un autre envers bien matériel de l’accroissement exponentiel de la place du numérique dans les sociétés humaines réside dans son impact écologique : 3,7 % des émissions totales de gaz à effet de serre dans le monde en 2020 (en regard de 4,7 % pour le transport aérien). Les trois quarts de cette empreinte écologique sont liés à la fabrication des smartphones et ordinateurs, mais le développement annoncé de la 5G va amplifier la consommation et nécessiter une extension des centres de données des géants du secteur, grands consommateurs de ressources d’eau et d’électricité.
Deux petits-enfants racontent…

Published: April 2023

À travers les récits familiaux de deux petits-enfants, l’auteure analyse quelques traces laissées par les catastrophes qui ont émaillé le XXe siècle. Les Amnésiques « C’étaient seulement des Mitlaüfer, ils marchaient avec le courant » de G. Schwartz révèle la participation des Mitlaüfer dans l’émergence des crimes nazis et l’après-coup de cette tragédie dans divers pays selon leur travail respectif de culture. A. Lecoq se demande si l’hyperindividualisme, le fractionnement de la pensée, le non-respect de la loi, la solidarité et les démocraties bafouées actuels ne feraient pas partie de l’héritage de ces catastrophes. Le Ghetto intérieur de S. Amigorena raconte le silence transgénérationnel qui blanchit toute trace d’un drame impensable, jusqu’à ce que l’auteur, par l’écriture, sorte lui-même de ce silence pour mettre en mots la souffrance indicible de son grand-père, lequel ne pouvait penser le trajet de sa mère du ghetto aux douches de Treblinka sauf en cauchemar. A. Lecoq insiste sur la transmission de la trace, même par la voie négative du silence.
