Abstract
We present the localization and host galaxies of one repeating and two apparently nonrepeating fast radio bursts (FRBs). FRB 20180301A was detected and localized with the Karl G. Jansky Very Large Array to a star-forming galaxy at z = 0.3304. FRB20191228A and FRB20200906A were detected and localized by the Australian Square Kilometre Array Pathfinder to host galaxies at z = 0.2430 and z = 0.3688, respectively. We combine these with 13 other well-localized FRBs in the literature, and analyze the host galaxy properties. We find no significant differences in the host properties of repeating and apparently nonrepeating FRBs. FRB hosts are moderately star forming, with masses slightly offset from the star-forming main sequence. Star formation and low-ionization nuclear emission-line region emission are major sources of ionization in FRB host galaxies, with the former dominant in repeating FRB hosts. FRB hosts do not track stellar mass and star formation as seen in field galaxies (more than 95% confidence). FRBs are rare in massive red galaxies, suggesting that progenitor formation channels are not solely dominated by delayed channels which lag star formation by gigayears. The global properties of FRB hosts are indistinguishable from core-collapse supernovae and short gamma-ray bursts hosts, and the spatial offset (from galaxy centers) of FRBs is mostly inconsistent with that of the Galactic neutron star population (95% confidence). The spatial offsets of FRBs (normalized to the galaxy effective radius) also differ from those of globular clusters in late- and early-type galaxies with 95% confidence.

Abstract
We detect Lyα absorption from the escaping atmosphere of HD 63433c, a R = 2.67R
⊕, P = 20.5 day mini-Neptune orbiting a young (440 Myr) solar analog in the Ursa Major Moving Group. Using Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph, we measure a transit depth of 11.1 ± 1.5% in the blue wing and 8 ± 3% in the red. This signal is unlikely to be due to stellar variability, but should be confirmed by an upcoming second transit observation with HST. We do not detect Lyα absorption from the inner planet, a smaller R = 2.15R
⊕ mini-Neptune on a 7.1 day orbit. We use Keck/NIRSPEC to place an upper limit of 0.5% on helium absorption for both planets. We measure the host star’s X-ray spectrum and mid-ultraviolet flux with XMM-Newton, and model the outflow from both planets using a 3D hydrodynamic code. This model provides a reasonable match to the light curve in the blue wing of the Lyα line and the helium nondetection for planet c, although it does not explain the tentative red wing absorption or reproduce the excess absorption spectrum in detail. Its predictions of strong Lyα and helium absorption from b are ruled out by the observations. This model predicts a much shorter mass-loss timescale for planet b, suggesting that b and c are fundamentally different: while the latter still retains its hydrogen/helium envelope, the former has likely lost its primordial atmosphere.

Abstract
We present observations of the dwarf galaxies GALFA Dw3 and GALFA Dw4 with the Advanced Camera for Surveys on the Hubble Space Telescope. These galaxies were initially discovered as optical counterparts to compact H i clouds in the GALFA survey. Both objects resolve into stellar populations which display old red giant branch (RGB), younger helium-burning, and massive main sequence stars. We use the tip of the RGB method to determine the distance to each galaxy, finding distances of

Mpc and

Mpc, respectively. With these distances we show that both galaxies are extremely isolated, with no other confirmed objects within ∼1.5 Mpc of either dwarf. GALFA Dw4 is also found to be unusually compact for a galaxy of its luminosity. GALFA Dw3 and Dw4 contain H ii regions with young star clusters and an overall irregular morphology; they show evidence of ongoing star formation through both ultraviolet and Hα observations and are therefore classified as dwarf irregulars (dIrrs). The star formation histories of these two dwarfs show distinct differences: Dw3 shows signs of a recently ceased episode of active star formation across the entire dwarf, while Dw4 shows some evidence for current star formation in spatially limited H ii regions. Compact H i sources offer a promising method for identifying isolated field dwarfs in the Local Volume, including GALFA Dw3 and Dw4, with the potential to shed light on the driving mechanisms of dwarf galaxy formation and evolution.

Abstract
We report the result of a search for neutrinos in coincidence with solar flares from the GOES flare database. The search was performed on a 10.8 kton-year exposure of KamLAND collected from 2002 to 2019. This large exposure allows us to explore previously unconstrained parameter space for solar flare neutrinos. We found no statistical excess of neutrinos and established 90% confidence level upper limits of 8.4 × 107 cm−2 (3.0 × 109 cm−2) on the electron antineutrino (electron neutrino) fluence at 20 MeV normalized to the X12 flare, assuming that the neutrino fluence is proportional to the X-ray intensity.
Standardized Long Gamma-Ray Bursts as a Cosmic Distance Indicator
Authors: Wang F. Y. , Hu J. P. , Zhang G. Q. , Dai Z. G. 
Published: January 2022

Abstract
Gamma-ray bursts (GRBs) are the most luminous explosions in and can be detectable out to the edge of the universe. They have long been thought to be able to extend the Hubble diagram to very high redshifts. Several correlations between temporal or spectral properties and GRB luminosities have been proposed to make GRBs cosmological tools. However, those correlations cannot be properly standardized. In this paper, we select a long-GRB sample with X-ray plateau phases produced by electromagnetic dipole emissions from central newborn magnetars. A tight correlation is found between the plateau luminosity and the end time of the plateau in the X-ray afterglows out to the redshift z = 5.91. We standardize these long-GRB X-ray light curves to a universal behavior through this correlation, with a luminosity dispersion of 0.5 dex. The derived distance–redshift relation of GRBs is in agreement with the standard ΛCDM model both at low and high redshifts. The evidence for an accelerating universe from this GRB sample is 3σ, which is the highest statistical significance from GRBs to date.
La modélisation des systèmes urbains : une approche par la physique statistique
Authors: Barthelemy Marc 
Published: January 2022

Les villes sont certainement parmi les systèmes les plus complexes construits par les humains. Elles sont constituées d'un grand nombre d’acteurs différents qui interagissent à différentes échelles, favorisant l’émergence de comportements collectifs qui invalident la modélisation naïve de ces systèmes. Heureusement, la disponibilité récente de données permet de construire une « science des villes » où la physique statistique joue un rôle important pour comprendre ces systèmes complexes.
Le « Biais Urbain » de Michael Lipton : théorie et critiques
Authors: Mien Edouard , Niedbalec Arnaud 
Published: January 2022

Dans son ouvrage de 1977 intitulé Pourquoi les pauvres restent-ils pauvres : Un biais urbain dans le développement mondial , Michael Lipton développait sa théorie du « biais urbain » caractérisant les politiques publiques des pays dits du « Tiers Monde ». En privilégiant les populations des zones urbaines au détriment des zones rurales, les politiques fiscales et monétaires de ces pays s’avéreraient inefficientes. Nous questionnerons ce « biais urbain » à l’aune des développements de son auteur et des différentes critiques qui lui ont été adressées.
Les types de guidage des processus d'apprentissage avec des ressources numériques
Authors: Amadieu Franck 
Published: January 2022

Dans le cadre des recherches sur la conception de ressources numériques pour l'apprentissage (par exemple, multimédia, hypertextes, animations, vidéos, documents sonores), de nombreuses études ont été menées sur l'efficacité de certains dispositifs de guidage pour accompagner l'apprenant dans son traitement des contenus et sa tâche d'apprentissage. Les ressources numériques qui se caractérisent par une grande étendue d'informations, une diversité de formats de présentation des informations, des modalités d'interaction avec les contenus, requièrent des ressources cognitives importantes pour être traitées efficacement. L'apprenant doit généralement engager des processus à différents niveaux de la tâche d'apprentissage : sélection, organisation, intégration, stratégies cognitives, métacognition. Pour répondre à ces exigences, un examen des revues de littérature et des méta-analyses sur la question des dispositifs de guidage dans les ressources numériques a été conduit. Cet examen a permis de déterminer les principes de guidage les plus efficaces selon les niveaux de processus engagés dans l'apprentissage à partir de ressources numériques. Des recommandations pédagogiques pour l'intégration du guidage dans ces apprentissages, ainsi que des perspectives de nouvelles recherches, sont discutées.

Published: January 2022

ABSTRACT
Pneumothorax is one of the most common emergencies encountered in day-to-day pulmonary practice. Early diagnosis and prompt intervention will reduce morbidity as well as mortality. The mainstay of treatment involves tube thoracostomy and drainage of pneumothorax in all except the mild cases. Proper technique and ascertaining correct tube position with follow-up imaging ensure successful lung expansion. We share the case of a gentleman who presented with nonexpansion of lung despite inserting 2 intercostal drainage tubes for the management of pneumothorax. Imaging with computed tomography thorax revealed both tubes to be coiled within the chest wall without entry into pleural space, thereby accounting for failed reexpansion. This case stresses the importance of following a structured evaluation in cases of nonexpanding lung after tube thoracostomy for pneumothorax.

ABSTRACT
Cryptococcus is a fungus that causes infections most commonly in immunocompromised patients. However, approximately one-third of cases of cryptococcosis are seen in patients who have no readily identifiable immune defects. Pulmonary cryptococcosis often manifests as isolated or multiple nodules, easily mimicking lung cancer clinically and radiologically. This case report highlights the tumor-like presentation of cryptococcosis in an immunocompetent patient.

Introduction:
Dentinal hypersensitivity (DH) is a common chronic condition that affects a high proportion of the adult population and is one of the main reasons why patients seek dental opinion and treatment. Despite considerable success in reducing DH, unfortunately, most of the present methods can provide only temporary and unpredictable desensitization. Therefore, new treatment methods that are effective for long periods and at the same time do not have the complications are needed. Recently, two new desensitizing agents BioMin F and Propolis have been introduced for the treatment of DH.

Aim:
The aim of the study was to compare and evaluate the efficacy of BioMin F and Propolis containing toothpastes on dentinal tubule occlusion with and without the use of an adjunct 810 nm Diode Laser.

Materials and Methods:
Forty-five freshly extracted teeth were taken out of which thirty were sectioned into halves and divided into four test groups BioMin F, Propolis, BioMin F + Laser, and Propolis + Laser and control group. All the specimens were treated twice a day for 7 days and then evaluated under scanning electron microscope for partial and complete dentinal tubule occlusion.

Results:
A significantly higher number of completely occluded tubules were seen in BioMin F + laser group followed by Propolis + laser, Biomin F, and Propolis.

Conclusion:
Combination approach of desensitizing agent and laser provided a better result than the desensitizing agent alone and when compared individually Biomin F was more effective desensitizer as compared to Propolis.
