Transdermal administration of adenosine using microplasma and the examination of the effect of microplasma on stratum corneum using infrared spectroscopy
Authors: Maliha Marium , Kristof Jaroslav , Rimi Sadia Afrin , Shimizu Kazuo 
Published: July 2023

Abstract
The strong barrier established by stratum corneum serves a protective purpose. It also prevents pharmacological compounds from being delivered via the epidermal layer. Microplasma discharge was used to overcome the barrier of epidermal layer to permeate adenosine. Depth of the microplasma effect into the stratum corneum layer was evaluated using tape striping method and attenuated total reflectance-Fourier transform IR spectroscopy (ATR-FTIR). Microplasma treatment caused increased permeability of stratum corneum lipids to a depth of several micrometers. The possible interaction between microplasma and stratum corneum lipids was studied on ceramide C4 by ATR-FTIR. Microplasma particles dominantly interacted with ceramide C4 at the bond between the NH and C=O causing possible dissociation and weakening of hydrogen bonding between molecules.

Published: July 2023

Abstract
Mapping out the populations of thick disk and halo brown dwarfs is important for understanding the metallicity dependence of low-temperature atmospheres and the substellar mass function. Recently, a new population of cold and metal-poor brown dwarfs has been discovered, with T
eff ≲ 1400 K and metallicity ≲−1 dex. This population includes what may be the first known “extreme T-type subdwarfs” and possibly the first Y-type subdwarf, WISEA J153429.75−104303.3. We have conducted a Gemini YJHK/Ks photometric follow-up campaign targeting potentially metal-poor T and Y dwarfs, utilizing the GNIRS and Flamingos-2 instruments. We present 14 near-infrared photometric detections of eight unique targets: six T subdwarf candidates, one moderately metal-poor Y dwarf candidate, and one Y subdwarf candidate. We have obtained the first-ever ground-based detection of the highly anomalous object WISEA J153429.75−104303.3. The F110W − J color of WISEA J153429.75−104303.3 is significantly bluer than that of other late T and Y dwarfs, indicating that WISEA J153429.75−104303.3 has an unusual spectrum in the 0.9–1.4 μm wavelength range which encompasses the J-band peak. Our J-band detection of WISEA J153429.75−104303.3 and corresponding model comparisons suggest a subsolar metallicity and temperature of 400–550 K for this object. JWST spectroscopic follow-up at near-infrared and mid-infrared wavelengths would allow us to better understand the spectral peculiarities of WISEA J153429.75−104303.3, assess its physical properties, and conclusively determine whether or not it is the first Y-type subdwarf.

Abstract
We present follow-up photometric observations and time-series analysis of a nova-like, SW Sextans-type, cataclysmic variable (CV) candidate, LAMOST J204305.95+341340.6 (hereafter J2043+3413), with a Gaia G-band magnitude of 15.30 and a distance of 990 pc, which was identified from the LAMOST spectrum. The photometric data were collected with the Tsinghua-NAOC 0.8 m telescope (TNT), Transiting Exoplanet Survey Satellite (TESS), Zwicky Transient Facility (ZTF), and ASAS-SN. The TESS light curve reveals the presence of two prominent periods of 2.587(8) hr and 1.09(5) days, corresponding to the orbital and superorbital (precession) period, respectively. The TNT data obtained in 2020 shows a possible quasiperiodic oscillation of 1426 s. The precession period is about three times shorter than that of CVs with similar orbital periods, indicating an unusually fast precessing accretion disk. The ZTF data is found to show a sudden decline of ∼0.4 mag on MJD 58979. From the intermittent behavior of the eclipse, we deduce that J2043+3413 is an intermediate inclination system of CV, similar to V795 Her, which is also situated in the period gap.
Search for Young and Intermediate-age Stellar Populations in the Galactic Center with Subaru/MOIRCS and CO Narrowband Filters
Authors: Nishiyama Shogo , Funamoto Naoya , Schödel Rainer 
Published: July 2023

Abstract
Extinction toward the Galactic Center (GC) is extreme and limits observations of its stars to the infrared. In addition, the extinction varies on scales of arcseconds. It is therefore highly challenging to distinguish between different stars photometrically and to identify young, massive, or intermediate-age stars that can trace recent star formation. Here we report the results of near-infrared imaging observations of a

region at the GC that encompasses the northwest part of the nuclear star cluster and parts of the nuclear stellar disk. We carried out the observations with the wide-field camera MOIRCS of the Subaru Telescope, using three narrowband (NB) filters. Two of the filters trace the stellar continuum, while we use the third one to measure the strength of the CO absorption features that are prominent in the spectra of cool giants, shallower in the spectra of warmer stars, and absent in young massive stars. Thus, we aim to distinguish between old late-type giants and young and intermediate-age stars. We have found 131 candidates of young and intermediate-age stars. The magnitude limit is ≈11.25 in the extinction-corrected K-band magnitude. The contamination of the candidates by old giants is estimated to be 26%. We show that our method allows us to identify correctly four out of five spectroscopically confirmed massive stars, and 68 of 75 spectroscopically confirmed cool stars (91%). Our results suggest that imaging observations with a CO NB filter can be complementary to other methods to identify massive stars in the GC.
A UFO Seen Edge-on? Resolving Ultrafast Outflow Emission on ∼200 pc Scales with Chandra in the Active Nucleus of Mrk 34

Published: July 2023

Abstract
We present Chandra ACIS imaging spectroscopy of the nucleus of the Seyfert 2 Galaxy Mrk 34. We identify spatially and spectrally resolved features in the band that includes Fe Kα, Fe xxv, and Fe xxvi. These features suggest high-velocity (≳15,000 km s−1 line-of-sight) material spanning ∼0.″5, within ∼200 pc of the nucleus. This outflow could have deprojected velocities ∼12–28× greater than the [O iii]-emitting outflows, and could potentially dominate the kinetic power in the outflow. This emission may point to the origins of the optical and X-ray winds observed at larger radii, and could indicate a link between ultrafast outflows and AGN feedback on ≳kiloparsec scales.

Abstract
We present a high-density relativistic reflection analysis of 21 spectra of six black hole X-ray binaries in the hard state with data from NuSTAR and Swift. We find that 76% of the observations in our sample require a disk density higher than the 1015 cm−3 assumed in the previous reflection analysis. Compared with the measurements from active galactic nuclei, stellar mass black holes have higher disk densities. Our fits indicate that the inner disk radius is close to the innermost stable circular orbit in the luminous hard state. The coronal temperatures are significantly lower than the prediction of a purely thermal plasma, which can be explained with a hybrid plasma model. If the disk density is fixed at 1015 cm−3, the disk ionization parameter is overestimated while the inner disk radius is unaffected.
A Quantum-mechanical Treatment of Electron Broadening in Strong Magnetic Fields
Authors: Gomez Thomas A. , Zammit Mark C. , Fontes Christopher J. , White Jackson R. 
Published: July 2023

Abstract
Spectral line-shape fitting is an extremely useful tool in determining the gravity of white dwarf stars. This method is so far limited to nonmagnetic white dwarfs largely because the theory of line broadening in high magnetic fields is not as complete as in the nonmagnetic case. Current Stark+Zeeman models treat plasma particles classically and ignore the motion of the nucleus. We develop the formalism for a quantum-mechanical treatment of the perturbing electrons and include the nuclear motion as part of the broadening and explore their relative importance. The conditions we explore are those found in white dwarf and neutron star atmospheres. We find that, contrary to previous studies, the quantized perturbing electrons create more broadening than perturbers on a straight-path trajectory. Additionally, the quantization of the plasma electrons gives rise to resonances away from the line center. The nuclear motion creates an additional electric field, which also leads to an increase in line broadening; however, this effect in neutron star atmospheres is not as large as previously estimated. This suggests that neutron star spectral lines are sensitive to density and that their mass and radius can be obtained from spectral line fitting, which would help constrain the neutron star equation of state.
Discovery of an Extended γ-Ray Emission around the Supernova Remnant Candidate Associated with PSR J0837–2454
Authors: Zhang Pengfei , Xin Yuliang 
Published: July 2023

Abstract
Motivated by the recent discovery of a low-surface-brightness diffuse emission, a supernova remnant (SNR) candidate, surrounding the young pulsar PSR J0837–2454, we carry out a likelihood analysis of the γ-ray data obtained by the Fermi Gamma-ray Space Telescope from 2008 August to 2022 November. Using a 2D Gaussian spatial template, we detect a significant extended γ-ray emission with a 68% containment radius of ∼1.°8, which is spatially coincident with the new SNR candidate at the ∼12σ confidence level. The spectrum of the extended γ-ray emission, obtained in the energy range of 0.1-500.0 GeV, shows a significant spectral curvature at ∼1 GeV, with a log-parabola spectral shape. Several scenarios, such as an SNR, pulsar wind nebula, and pulsar halo, are discussed as the potential origins of the extended γ-ray emission, and our model fitting results are preferred for the SNR scenario.
L’Exposition Universelle de 1900 et le voyage Barcelone - Paris
Authors: Freixa Mireia 
Published: July 2023

L’Exposition Universelle de 1900 de Paris revêt une importance particulière pour sa contribution à la diffusion de l’Art nouveau, un style que l’on perçoit pourtant davantage dans la rue que dans les pavillons officiels de l’Exposition construits encore dans un style éclectique. Le pavillon espagnol de José de Urioste devient la référence de la nouvelle architecture régionaliste d’Espagne mais cet événement a exercé une influence relative sur l’art et l’architecture en Catalogne car la modernité s’était déjà engagée une dizaine d’années auparavant, sur la voie de ce qu’on a appelé le « premier modernisme », depuis l’Exposition Universelle de Barcelone de 1888. Mais l’exposition de Paris exerce un énorme pouvoir d’attraction sur les artistes et les intellectuels catalans et sensibilise la culture catalane à l’esprit cosmopolite et devient surtout un modèle de ville – grande métropole européenne – dont Barcelone se veut être le reflet. La recherche a été faite à partir de matériaux qui attestent du succès de l’événement : catalogues, cartes postales, brochures touristiques, lettres et documents personnels, conservés dans des archives et avec le magazine hebdomadaire Pèl & Ploma.
Vestir la pintura: el mite de «la parisenca» i Ramon Casas
Authors: Aragonès Riu Núria 
Published: July 2023

Depuis la deuxième moitié du XIXe siècle nous assistons à la construction du « mythe » de la Parisienne en tant qu’icône de mode et de modernité dans les arts et la littérature. Quelques peintres et dessinateurs du modernisme catalan, notamment Ramon Casas, adoptèrent le motif iconographique de la jeune femme parisienne et s’en servirent comme source d’inspiration pour habiller les femmes qui peuplaient leurs illustrations. Notre but ici est d’approcher les rapports que ces peintres entretinrent avec la mode dans le cadre de leur création artistique et d’en faire ressortir l’influence du modèle parisien.
Entre matrice territoriale et enjeux sectoriels
Authors: Itçaina Xabier 
Published: July 2023

L’article revisite la question de l’ancrage territorial des coopératives au prisme d’un cadre d’analyse croisant la sociologie du travail politique et l’approche régulationniste « méso ». Ce cadrage général est mis à l’épreuve à partir d’une étude de cas portant sur les coopératives de production (SCOP) du Pays basque français, considérées comme un mouvement social économique aspirant à refonder le développement local sur une base coopérative, territoriale et intersectorielle. Les visions du développement territorial ainsi véhiculées ne sont cependant pas statiques. Nous en proposons dès lors une lecture sociohistorique en distinguant trois séquences. La genèse du mouvement, d’une part, se caractérise dans les années 1970 par sa politisation, les fondateurs des SCOP se référant à un modèle de développement économique endogène, au modèle transfrontalier de Mondragón, à l’identité territoriale et à des registres hérités de coopération. Dans une deuxième phase, le mouvement connaitra un ralentissement dû à quelques échecs entrepreneuriaux. Les contraintes sectorielles et marchandes mettent alors à l’épreuve le modèle coopératif et l’inter-coopération. Une troisième phase, à compter des années 2000, voit un redéploiement des coopératives dans le cadre d’un spectre élargi de mobilisations citoyennes autour de l’économie sociale et solidaire mais aussi de la transition écologique, de la langue et de la culture basques, ce redéploiement coïncidant avec un changement substantiel de la gouvernance territoriale. La section conclusive revient sur quelques enseignements à portée générale concernant l’ancrage territorial des coopératives.
Analyser la politique économique à partir de facteurs sociaux
Authors: Eloire Fabien , Dallery Thomas 
Published: July 2023

L’article montre l’intérêt d’une approche interdisciplinaire pour analyser la prise de décision en matière de politiques économiques. Il prend appui sur l’exemple du « tournant de la rigueur » en France, opéré en 1983 par le gouvernement socialiste. Cet épisode demeure encore, 40 ans plus tard, une référence incontournable des débats politiques relatifs à l’exercice du pouvoir par les forces de gauche. Au travers de l’étude des fonds d’archive des conseillers de l’Élysée et de données macroéconomiques, l’article donne à voir l’évolution de la controverse entre partisans de la relance et avocats de la rigueur, en précisant les stratégies suivies par ces derniers pour emporter l’adhésion du président Mitterrand. Le « tournant » de la rigueur n’apparaît alors ni comme le seul produit de circonstances économiques (contrainte extérieure) imposant ce choix, ni comme le seul fruit d’une conversion idéologique (néolibérale) des gouvernants, ni enfin comme la seule conséquence d’un travail relationnel d’un front de conseillers, mais comme le produit de ces différentes causes.
Coopératives de production : quelle spécificité du rapport social d’activités coopératif à l’aune du rapport salarial ?
Authors: Ballon Justine , Celle Sylvain , Fretel Anne , Vallade Delphine 
Published: July 2023

Cet article analyse les coopératives de production en questionnant leur capacité à produire un rapport social d’activités relativement autonome et protecteur vis-à-vis du rapport salarial dominant. En prenant appui sur les travaux régulationnistes consacrés au rapport salarial et au rapport social d’activité, nous proposons une lecture basée sur la conceptualisation d’un « rapport social d’activités coopératif » spécifique, fondé sur le principe de double qualité. Il se caractérise par quatre composantes principales : 1) la futurité ; 2) la gouvernance ; 3) l’organisation du travail ; 4) les revenus et mutualisations. À travers une relecture historique et la mise en lumière de faits stylisés, nous considérons l’évolution historique du « rapport social d’activités coopératif » dans les coopératives de production en France, au regard de l’évolution du rapport salarial. Trois principales périodes sont dégagées : 1815-1910 avec un « rapport social d’activités coopératif » alternatif à l’émergence du salariat ; 1910-1980 avec son assimilation dans la société salariale ; enfin à partir des années 1980 avec le retour d’un idéal contournant la subordination salariale. Au regard de cette lecture théorique et historique du « rapport social d’activités coopératif », nous questionnons sa capacité à produire des formes de protection et de sécurisation salariale au sein de l’entreprise face à un rapport salarial de plus en plus précaire. Nous mettons finalement en discussion le fait que la gouvernance démocratique serait non seulement un élément clé de différenciation du « rapport social d’activités coopératif », mais aussi une condition pour produire une protection salariale dans l’entreprise.
Study of mosquito (Culicidae) larvae and characterisation of water bodies in urban and periurban areas

Published: July 2023

Abstract
Urbanisation has modified the distribution and community composition of mosquito species (Culicidae). Habitat disturbance may increase the risk of loss of species diversity and the occurrence of vector-borne diseases. Studies on the presence of larvae and the eco-physicochemical characteristics of water bodies near urban areas provide information on the risk of these diseases. In this study, the presence of larvae in different types of urban and periurban water bodies in Villahermosa City, Tabasco, Mexico was analysed. The eco-physicochemical characteristics of each collecting site were measured. A total of 67 528 larvae were collected, 1366 were identified to species, and 15 species were observed. Although Culex spp. were the most dominant species, Anopheles albimanus was the only species present in all habitats. Despite the large variability in the parameters measured (especially in physicochemical parameters; e.g., pH, electrical conductivity, total dissolved solids), differences were observed among the breeding sites. Weak correlations were found between eco-physicochemical parameters and species presence. Predators may have a major role in determining community processes in the region. Habitat disturbance may be responsible for eco-physicochemical variations altering mosquito community composition, resulting in the loss of endemic mosquito species and increasing the risk of vector-borne diseases in Villahermosa.
Severe Acute Respiratory Syndrome Coronavirus 2 Infection Symptoms in Pregnancy and Maternal and Neonatal Complications Due to COVID-19: A Systematic Review
Authors: Miraj Sepideh , Asgarian Azadeh , Mohammadbeigi Abolfazl , Derakhshani Maryam 
Published: July 2023

Background:
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnant women is associated with severe maternal and neonatal complications including maternal and newborn death.

Aims:
This review aimed to assess the SARS-CoV-2 infection symptoms during pregnancy as well as maternal and neonatal complications in Iran.

Settings and Design:
A developing and low-income country and a systematic review.

Materials and Methods:
International scientific databases including PubMed, Web of Science, Scopus and Google Scholar were searched in a systematic review manner. Two independent researchers were checked and identified articles from September 2019 to September 2022 based on eligibility criteria and quality appraisal. The results of review were reported in two sections including maternal and neonatal outcomes.

Statistical Analysis Used:
Descriptive statistics was used for statistical analysis.

Results:
Seventeen studies including 870 pregnant mothers with COVID-19 met the eligibility criteria and were reviewed. The main maternal consequences of COVID-19 were intensive care unit (ICU) admission, pre-term delivery, maternal death, pre-mature rupture of membranes, pre-eclampsia, intrauterine growth retardation and stillbirth. Neonatal ICU admission, newborn death, neonatal sepsis, low birth weight and respiratory distress syndrome, tachypnoea, asphyxia and pneumothorax were the most common outcomes of COVID-19 infection in offspring of pregnant subjects.

Conclusion:
Pregnant mothers with COVID-19 infection are at higher risk of being admitted to the ICU and mechanical ventilation and consequently maternal and neonatal death. Comparing the maternal and foetal consequences in different ethnicities, regions and countries may be related to the socioeconomic status of people and should be considered with respect to different determines. Moreover, the maternal and neonatal complications due to COVID-19 infection in Iran and other developing countries seem to be higher than other countries.
