Published: May 2022

BackgroundHemodynamic changes caused by hybrid surgery for brain arteriovenous malformations (bAVM) are usually related to long-term lesions from “blood stealing”. There are currently no viable low-cost, noninvasive procedures for assessing cerebral perfusion in the operating room. This study aims to investigate the use of intraoperative laser speckle contrast image (LSCI) software in AVM surgery.MethodsIn Zhongnan Hospital of Wuhan University, 14 patients who underwent surgery with LSCI were collected. To analyze the hemodynamic features of AVM and the influence on the peripheral cortex of AVM embolization and resection, we assessed the transit time between feeding arteries and drainage veins by intraoperative digital subtraction angiography (DSA). Meanwhile, LSCI was performed at pre-embolization, post-embolization, and after complete resection of bAVM.ResultsIn this study, the transit time of bAVM before and after embolization was compared, the transit time before embolization was significantly shorter than that after embolization (p &lt; 0.05). We also got good visualization of relative CBF, in addition, to flow imaging in the cortical vasculature round bAVM with LSCI. The flux of post-surgery was significantly higher than pre-embolization (p &lt; 0.01).ConclusionHemodynamic variable assessment plays an important role in the resection of AVM in the hybrid operative room and LSCI can be used to visualize and evaluate cortical cerebral blood flow to detect pathological hyperperfusion in real-time with a good spatial-temporal resolution in a sensitive and continuous, non-invasive mode.

Intensive balance and coordination training is the mainstay of treatment for symptoms of impaired balance and mobility in individuals with hereditary cerebellar ataxia. In this study, we compared the effects of home-based balance and coordination training with and without vibrotactile SA for individuals with hereditary cerebellar ataxia. Ten participants (five males, five females; 47  ±  12 years) with inherited forms of cerebellar ataxia were recruited to participate in a 12-week crossover study during which they completed two six-week blocks of balance and coordination training with and without vibrotactile SA. Participants were instructed to perform balance and coordination exercises five times per week using smartphone balance trainers that provided written, graphic, and video guidance and measured trunk sway. The pre-, per-, and post-training performance were assessed using the Scale for the Assessment and Rating of Ataxia (SARA), SARAposture&gait sub-scores, Dynamic Gait Index, modified Clinical Test of Sensory Interaction in Balance, Timed Up and Go performed with and without a cup of water, and multiple kinematic measures of postural sway measured with a single inertial measurement unit placed on the participants’ trunks. To explore the effects of training with and without vibrotactile SA, we compared the changes in performance achieved after participants completed each six-week block of training. Among the seven participants who completed both blocks of training, the change in the SARA scores and SARAposture&gait sub-scores following training with vibrotactile SA was not significantly different from the change achieved following training without SA (p>0.05). However, a trend toward improved SARA scores and SARAposture&gait sub-scores was observed following training with vibrotactile SA; compared to their pre-vibrotacile SA training scores, participants significantly improved their SARA scores (mean=−1.21, p=0.02) and SARAposture&gait sub-scores (mean=−1.00, p=0.01). In contrast, no significant changes in SARA scores and SARAposture&gait sub-scores were observed following the six weeks of training without SA compared to their pre-training scores immediately preceding the training block without vibrotactile SA (p>0.05). No significant changes in trunk kinematic sway parameters were observed as a result of training (p>0.05). Based on the findings from this preliminary study, balance and coordination training improved the participants’ motor performance, as captured through the SARA. Vibrotactile SA may be a beneficial addition to training regimens for individuals with hereditary cerebellar ataxia, but additional research with larger sample sizes is needed to assess the significance and generalizability of these findings.

Abstract
The electrochemical Seebeck coefficient (α) of Fe2+/Fe3+ in acetone–methanol (MeOH) mixed solution was systematically investigated against the acetone molar ratio (n) and molar ratio of Fe3+ to Fe (n
Fe3+). At n
Fe3+ = 0.75, α monotonously increases with increase in n from 0.3 mV K−1 at n = 0.00 to 3.4 mV K−1 at n = 1.00. At n
Fe3+ = 0.50 and 0.25, we found anomalous dip structures in the n−α plot at n ≈ 0.9 and 0.4, respectively. Based on a spectroscopic investigation, we interpreted the observed dip structures in terms of the transition state between the FeCl4-active and FeL
6-active regions.

Published: May 2022

Abstract
In this study, we newly considered the analysis of capillary flow under differential pressure, which extends the previous study and allows the independent measurement of relative viscosity and the product of relative surface tension and contact angle for low-volume samples. The theory of this method is explained, and it is demonstrated that relative viscosity and surface tension with contact angle can be obtained independently by measuring the capillary flow under differential pressure. We conducted capillary flow experiments with a small sample volume (less than 100 μl) using a measurement system comprising a flow measurement unit, capillary chip, and differential pressure mechanism. The relative viscosities of pure water and dilute ethanol solutions obtained in the experiment were in one-to-one correspondence with the values in the Chemical Handbook. This also shows that relative surface tension can be determined using these measurement results and the separately measured contact angle values.

Abstract
We report on the high-power and room temperature operation of an Er:Y2O3 ceramic laser at ∼2.7 μm based on home-developed high optical quality ceramic samples. Pumped directly into the upper laser level with a spectrally narrowed 976 nm laser diode beam shaped to have a 1D top-hat profile, the laser-generated 13.4 W of CW output power with a slope efficiency of 16.0% with respect to absorbed pump power. In a modified resonator design, a lasing slope efficiency of 23.7% has been demonstrated. To our knowledge, this represents the highest power at ∼2.7 μm spectral region from a room temperature sesquioxide laser.
On the possibility of creating a unified law of motion of matter
Authors: Rukhlyada Vladimir , Rukhlyada Oksana 
Published: May 2022

In work [1] a hypothetical model of the Universe is given and some laws of objective and subjective interaction of matter are given, preserving maternal chaos and daughter orders. Chaos and order in the Galaxy and the Solar System, as a way of existence of matter, are possible in interactions. A homogeneous maternal environment, as a subject, exists observing a single law of motion of particles, the population of which is organized by chaos. The main advantage of the unified law is the quantitative diagnosis of violation of the law and its restoration by the counter movement of particles. The number of particles participating in the oncoming motion is equivalent to the number of particles that have disturbed the movement of matter, which leads to the restoration of a single law of particle motion. The work shows the restoration (treatment) of the law by the planets of the solar system.
LEARNING HABITS: DOES THE DIGITAL GENERATION HAVE DIGITAL STRESS AND HOW DOES IT AFFECT THE LEARNING OF MATHEMATICS?
Authors: Cunska Aija 
Published: May 2022

Mathematics is one of the most important subjects that students learn at all levels of education. Understanding and competence in mathematics allows to integrate better into the labour market, perform complex calculations and model significant processes. It is mathematics that has been proven to be the most sensitive to compulsory distance learning as a result of the Covid-19 pandemic. Due to the state of emergency in Latvia, all schools were periodically closed for a total of 9 months, when the learning process could only take place in the e-environment. In this context, the study was motivated by the question "Does digital stress exist for the digital generation and how does it affect the learning of mathematics?" The aim of the study is to determine the initiators of digital stress by using the Stressor-strain-outcome framework and the consequences that students face when learning math remotely. Using the Partial Least Squares Structural Equation Modelling with SmartPLS, a survey data of 185 students were analyzed. Anxiety, lack of instantaneous feedback, risks of self-directed learning and social isolation were found to contribute to digital stress, which in turn has a negative impact on interest and performance in learning mathematics. The study helped to delve into students' feelings and needs, as well as to develop recommendations to reduce the effects of the pandemic, to manage learning processes more effectively, to gain students' respect and to promote better learning in mathematics.
Staring at the Shadows of Archaic Galaxies: Damped Lyα and Metal Absorbers Toward a Young z ∼ 6 Weak-line Quasar

Abstract
We characterize the Lyα halo and absorption systems toward PSO J083+11, a unique z = 6.3401 weak-line quasar, using Gemini Near-infrared Spectrograph, Magellan Folded-port Infrared Echellette, and Very Large Telescope Multi Unit Spectroscopic Explorer (MUSE) data. Strong absorptions by hydrogen and several metal lines (e.g., C ii, Mg ii, and O i) are discovered in the spectrum, which indicates the presence of: (i) a proximate subdamped Lyα (sub-DLA) system at z = 6.314 and (ii) a Mg ii absorber at z = 2.2305. To describe the observed damping wing signal, we model the Lyα absorption with a combination of a sub-DLA with the neutral hydrogen column density of

and absorption from the intergalactic medium with a neutral fraction of around 10%. The sub-DLA toward PSO J083+11 has an abundance ratio of [C/O] = −0.04 ± 0.33 and metallicity of [O/H] = −2.19 ± 0.44, similar to those of low-redshift metal-poor DLAs. These measurements suggest that the sub-DLA might truncate PSO J083+11’s proximity zone size and complicate the quasar lifetime measurement. However, this quasar shows no sign of a Lyα halo in the MUSE data cube, where the estimated 1σ limit of surface brightness is

at an aperture size of 1″, or equivalent to a Lyα luminosity of ≤43.46 erg s−1. This nondetection, while being only weak independent evidence on its own, is at least consistent with a young quasar scenario, as expected for a quasar with a short accretion timescale.
Cloudy and Cloud-free Thermal Phase Curves with PICASO: Applications to WASP-43b
Authors: Robbins-Blanch Nina , Kataria Tiffany , Batalha Natasha E. , Adams Danica J. 
Published: May 2022

Abstract
We present new functionality within PICASO, a state-of-the-art radiative transfer model for exoplanet and brown dwarf atmospheres, by developing a new pipeline that computes phase-resolved thermal emission (thermal phase curves) from three-dimensional (3D) models. Because PICASO is coupled to Virga, an open-source cloud code, we are able to produce cloudy phase curves with different sedimentation efficiencies (f
sed) and cloud condensate species. We present the first application of this new algorithm to hot Jupiter WASP-43b. Previous studies of the thermal emission of WASP-43b from Kataria et al. found good agreement between cloud-free models and dayside thermal emission, but an overestimation of the nightside flux, for which clouds have been suggested as a possible explanation. We use the temperature and vertical wind structure from the cloud-free 3D general circulation models of Kataria et al. and post-process it using PICASO, assuming that clouds form and affect the spectra. We compare our models to results from Kataria et al., including Hubble Space Telescope Wide-Field Camera 3 (WFC3) observations of WASP-43b from Stevenson et al. In addition, we compute phase curves for Spitzer at 3.6 and 4.5 μm and compare them to observations from Stevenson et al. We are able to closely recover the cloud-free results, even though PICASO utilizes a coarse spatial grid. We find that cloudy phase curves provide much better agreement with the WFC3 and Spitzer nightside data, while still closely matching the dayside emission. This work provides the community with a convenient, user-friendly tool to interpret phase-resolved observations of exoplanet atmospheres using 3D models.

Abstract
We present an overview of best practices for publishing data in astronomy and astrophysics journals. These recommendations are intended as a reference for authors to help prepare and publish data in a way that will better represent and support science results, enable better data sharing, improve reproducibility, and enhance the reusability of data. Observance of these guidelines will also help to streamline the extraction, preservation, integration and cross-linking of valuable data from astrophysics literature into major astronomical databases, and consequently facilitate new modes of science discovery that will better exploit the vast quantities of panchromatic and multidimensional data associated with the literature. We encourage authors, journal editors, referees, and publishers to implement the best practices reviewed here, as well as related recommendations from international astronomical organizations such as the International Astronomical Union for publication of nomenclature, data, and metadata. A convenient Checklist of Recommendations for Publishing Data in the Literature (Appendix A) is included for authors to consult before the submission of the final version of their journal articles and associated data files. We recommend that publishers of journals in astronomy and astrophysics incorporate a link to this document in their Instructions to Authors.
Au regard des processus tertiaires
Authors: Gutton Philippe 
Published: May 2022

L’article situe les processus tertiaires (A. Green) en tant que travail de subjectivation. Ils prennent origine dans le lien avec le premier objet subjectal, la mère. Les processus tertiaires ont deux versants intriqués : négatif, cherchant à trier dans le pouvoir des objets extérieurs (travail de l’hallucination négative) ; positifs, la créativité psychique, la représentance partagée en trois angles d’étude : l’affect, la représentation interne-externe d’objet et la représentation de mot.
Le surmoi perverti. Bisexualité psychique et états limites
Authors: Servant Benoît 
Published: May 2022

L’intérêt de F. Richard pour la clinique des adolescents et des états limites d’une part, et l’évolution psychosociale et culturelle d’autre part, est au centre de son nouvel ouvrage très riche, dans lequel il articule ces deux dimensions. L’auteur propose d’établir un lien entre l’augmentation de la pathologie limite et l’évolution du malaise dans la culture, en lien à une pervertisation du surmoi (double injonction contradictoire de libération et de puritanisme).
Identification et contamination : du virus à l’amour
Authors: Assoun Paul-Laurent 
Published: May 2022

Dans quelle mesure la contagion, comme phénomène organique et processus social, ressortit-elle à la logique inconsciente ? Répondre à cette question passe par une exploration sémantique précise du signifiant « contagion » chez Freud, en tant que ce phénomène renvoie à la clinique du sujet. La « contagion psychique » mise au jour depuis l’hystérie renvoie à la dialectique de l’identification, entre symptôme et lien social – puis à l’obsession de la contamination, de la paranoïa au « délire à deux ». C’est la question du tabou qui en éclaire l’enjeu symbolique. On trouve à partir de là un point de bascule dans la question majeure de la réciprocité des sentiments, en opposition à la disparité subjective. Réaborder l’amour comme « maladie contagieuse » : ce chassé-croisé, pour être vertigineux, n’en éclaire que mieux la question du lien entre affection et infection et permet de revenir à la condition pandémique qui, gommant le sexuel, n’en est pas moins éclairé par la si bien dite « maladie d’amour ».
Rêves de pandémie, pandémie de rêves
Authors: Lafarge Isabelle 
Published: May 2022

Quand des événements fracassants tels que la pandémie de la Covid 19 impactent la collectivité, ils envahissent rêves et cauchemars de nos patients, compliquant le travail du rêve par un effet traumatique qui occupe le devant de la scène. Est-il possible de faire la part des choses entre la réalité qui s’impose dans toute sa brutalité et la conflictualité psychique qui s’en accapare ? Entre la problématique individuelle et collective ? Quelle est la fonction de tels rêves si répandus qu’ils en deviennent typiques ? L’auteure tente d’apporter quelques éclaircissements théoriques et de nombreux rêves à ces questions en se basant sur les théories freudiennes et postfreudiennes des rêves.
Le complotisme : maladie des mal-pensants ?
Authors: Arnal Camila , Kolinsky Régine , Klein Olivier 
Published: May 2022

Dans cet article, nous aborderons la question des théories du complot et les facteurs menant certaines personnes à adhérer à ces récits. Nous examinerons d’abord les explications individuelles, en termes de déficit cognitif et/ou de psychopathologie. Celles-ci nous amèneront à interroger le lien entre niveau d’éducation et complotisme : le complotisme trouve-t-il sa source dans un déficit de pensée critique, que l’instruction scolaire pourrait combler ? Dans un troisième temps, nous soulignerons les limites d’une approche individuelle du complotisme en mettant en exergue le rôle de dynamiques collectives, qui ne sont pas réductibles à des déficits cognitifs et/ou à des troubles psychopathologiques.
Contagion à la brésilienne
Authors: Mezan Renato 
Published: May 2022

La gestion désastreuse de la pandémie de Covid-19 par le gouvernement fédéral du Brésil a eu pour conséquence la perte de plus de 600 000 vies. La raison principale de cette tragédie a été la position négationniste du président Jair Bolsonaro, qui a aggravé une situation politique et économique déjà précaire. Cet article la décrit, reprend quelques actes significatifs du gouvernement qu’il dirige, cite un échantillon de ses déclarations sur la pandémie, et suggère des hypothèses sur les raisons de son négationnisme. Ensuite, l’auteur propose une interprétation psychanalytique des attitudes des Brésiliens par rapport à la pandémie, qui ont dans une certaine mesure changé au fur et à mesure que se répandait la vaccination. D’après lui, cela s’explique (au moins en partie) parce que la sensation de sécurité produite par l’immunisation a remplacé avec des avantages pour l’économie psychique certains mécanismes défensifs jusqu’alors largement utilisés. Il confronte cette hypothèse à des considérations d’autres psychanalystes, et aux conclusions d’une expérimentation de l’université de Californie dont le but était d’induire les récalcitrants à se vacciner.
Analyse tri-générationnelle du processus adolescentaire au regard du contexte sociétal individualiste actuel
Authors: Gouder De Beauregard Sophie , Mottrie Cindy , Duret Isabelle 
Published: May 2022

Cet article interroge la transition vers l’âge adulte dans le monde occidental contemporain, où la mythique individualiste est prégnante. Nous avons voulu explorer l’impact de ce discours sur le processus d’individuation propre à l’adolescence. Pour ce faire, nous avons observé et analysé le fonctionnement trigénérationnel de 4 familles « tout-venant » avec un adolescent de genre masculin, afin de voir quelles étaient la créativité et la restructuration de leur système familial. Cette transformation a été étudiée suivant une approche systémique sous trois angles : celui de l’adolescent, du couple parental et celui des grands-parents. Notre travail a permis de mettre en évidence, à une échelle certes petite, l’importance du travail de transformation au sein de chaque famille. L’implication du groupe familial dans la transition permet de constituer une sorte de « moi-peau familial » suffisamment contenante afin d’organiser ce passage à l’âge adulte pour ces 4 adolescents.
