The violin crab Uca spp. is a benthic organism that has an ecological role in the mangrove ecosystems. Passo mangrove ecosystem is degraded which can threaten the existence of violin crabs. The study was held in May-June 2023 to analyze the species composition and density of violin crabs. The results of the study can be used as basic data for the violin crabs and their habitat management. The study was conducted at 3 stations using the purposive sampling method. Sampling of violin crabs and substrate structures at each station was carried out at the lowest low tide using the plot method randomly. Data of violin crab species were calcified based on taxon. Data of substrate are classified by presentation of each fraction. Seven species of violin crabs are found in the study namely U. annulipes, U. perplexa, U. vocans, U. mjorbergi, U. lactea, U. dussumieri, and U. vomaris. The total density of violin crabs ranges from 8.1-29.9 ind/m2. The total highest density of violin crab is found in station 1 and lowest at station 2. Species densities differ between stations.

Abstract
We examine the wavelength dependence of radial light profiles based on Sérsic index n measurements of 1067 galaxies with M
* ≥ 109.5
M
⊙ and in the redshift range 0.5 < z < 3. The sample and rest-frame optical light profiles are drawn from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) and 3D Hubble Space Telescope (HST); rest-frame near-infrared light profiles are inferred from images collected for the Cosmic Evolution Early Release Science (CEERS) program with the Near Infrared Camera (NIRCam) on board of the James Webb Space Telescope (JWST). n shows only a weak dependence on the wavelength, regardless of the redshift, galaxy mass, and type. On average, star-forming galaxies have n = 1–1.5 and quiescent galaxies have n = 3–4 in the rest-frame optical and near-infrared. The strong correlation at all wavelengths between n and star formation activity implies a physical connection between the radial stellar mass profile and star formation activity. The main caveat is that the current sample is too small to discern trends for the most massive galaxies (M
* > 1011
M

Determining the Orbital Period and Wind Geometry in GRO J1655–40
Authors: Petretti C. , Neilsen J. , Homan J. 
Published: October 2023

Abstract
During the course of its 2005 outburst, the black hole X-ray binary GRO J1655–40 launched an accretion disk wind associated with deep X-ray absorption lines and strong Compton scattering. Little is known about this apparently super-Eddington wind, but previous works have discovered optical/infrared (OIR) emission from the wind that varies on the orbital period—a possible clue to its origin and geometry. However, there is significant uncertainty in the orbital phases, and a more precise value of the orbital period is needed to accurately phase fold the wind emission. We present our analysis of the I-band photometry from observations taken with the Small and Medium Aperture Research Telescope System 1.3 m telescope between 2006 and 2016. We have implemented two methods—data-driven and model-based—to determine the orbital period, which we report as 2.62193 ± 0.00002 days from the data-driven method and 2.621928 ± 0.000004 days from the model-based method, a significant (25×) increase in precision over prior measurements. We discuss the possible existence of a period derivative, implications of a peculiar deep minimum in the outburst lightcurve of the system, and connections between OIR variability and the geometry of the super-Eddington wind.
The Statistical Uncertainties on X-Ray Flux and Spectral Parameters from Chandra ACIS-I Observations of Faint Sources: Application to the Cygnus OB2 Association

Published: October 2023

Abstract
We investigate the uncertainties of fitted X-ray model parameters and fluxes for relatively faint Chandra ACIS-I source spectra. Monte Carlo (MC) simulations are employed to construct a large set of 150,000 fake X-ray spectra in the low photon count statistics regime (from 10 to 350 net counts) using the XSPEC spectral model-fitting package. The simulations employed both absorbed thermal (APEC) and nonthermal (power-law) models, in concert with the Chandra ACIS-I instrument response and interstellar absorption. Simulated X-ray spectra were fit assuming a wide set of different input parameters and C-statistic minimization criteria to avoid numerical artifacts in the accepted solutions. Results provide an error estimate for each parameter (absorption, N
H, plasma temperature, kT, or power-law slope, Γ, and flux) and for different background contamination levels. The distributions of these errors are studied as a function of the 1σ quantiles, and we show how these correlate with different model parameters, net counts in the spectra, and relative background level. Maps of uncertainty in terms of the 1σ quantiles for parameters and flux are computed as a function of spectrum net counts. We find very good agreement between our estimated X-ray spectral parameter and flux uncertainties and those recovered from spectral fitting for a subset of the X-ray sources detected in the Chandra Cygnus OB2 Legacy Survey diagnosed to be association members and that have between 20 and 350 net counts. Our method can provide uncertainties for spectral parameters whenever formal X-ray spectral fits cannot be well constrained, or are unavailable, and predictions useful for computing Chandra ACIS-I exposure times for observation planning.
Quand les écrans « font écran » dans la famille. D’une transparence digitale qui favorise les liens à une technoférence qui les appauvrit
Authors: Tordo Frédéric , Darchis Élisabeth , Duris Olivier 
Published: October 2023

Si de nombreuses études s’attardent aujourd’hui sur la place importante qu’occupe la consommation des écrans dans la vie des tout-petits, nous observons au contraire un manque de littérature sur l’appauvrissement des interactions dans la famille, provoqué par l’usage intensif des écrans nomades. Ce phénomène porte pourtant un nom, la technoférence parentale. Cependant, les « écrans » ne sont pas seulement des espaces de déliaison, ils peuvent également être l’occasion de créer des espaces singuliers de liaison, avec des effets de transparence psychique des processus, des liens et du groupe (par exemple lors de consultations en ligne). Ce phénomène porte aussi un nom, la transparence digitale.
Adolescence et santé mentale, quand les réseaux sociaux s’en mêlent… Le cas du cyber-harcèlement
Authors: de Marneffe Emmanuelle , Lambotte Isabelle 
Published: October 2023

La santé mentale des adolescents inquiète de plus en plus avec des chiffres alarmants concernant les troubles anxieux et dépressifs, et les risques suicidaires. Leur étiologie est multidimensionnelle. Les réseaux sociaux et plus particulièrement le cyberharcèlement participent au maintien ou à l’aggravation de la santé mentale des adolescents. Au sein d’une consultation pédopsychiatrique pluridisciplinaire (médecins, psychologues, assistante sociale, logopèdes, neuropsychologues), nous proposons un dispositif d’intervention systémique pour contrer les effets néfastes de cette dynamique relationnelle en redonnant du pouvoir à la « victime », en renforçant les relations d’appartenance du jeune et en aidant les parents à comprendre l’ambivalence de la communication à l’adolescence. En parallèle, un travail préventif de collaboration avec le réseau (école, centre PMS, cabinet médical) nous semble indispensable.
