Abstract
Earth-sized exoplanets that transit nearby, late-spectral-type red dwarfs will be prime targets for atmospheric characterization in the coming decade. Such systems, however, are difficult to find via widefield transit surveys like Kepler or TESS. Consequently, the presence of such transiting planets is unexplored and the occurrence rates of short-period Earth-sized planets around late-M dwarfs remain poorly constrained. Here, we present the deepest photometric monitoring campaign of 22 nearby late-M dwarf stars, using data from over 500 nights on seven 1–2 m class telescopes. Our survey includes all known single quiescent northern late-M dwarfs within 15 pc. We use transit injection-and-recovery tests to quantify the completeness of our survey, successfully identify most (>80%) transiting short-period (0.5–1 days) super-Earths (R >1.9 R
⊕), and are sensitive (∼50%) to transiting Earth-sized planets (1.0–1.2 R
⊕). Our high sensitivity to transits with a near-zero false-positive rate demonstrates an efficient survey strategy. Our survey does not yield a transiting planet detection, yet it provides the most sensitive upper limits on transiting planets orbiting our target stars. Finally, we explore multiple hypotheses about the occurrence rates of short-period planets (from Earth-sized planets to giant planets) around late-M dwarfs. We show, for example, that giant planets with short periods (<1 day) are uncommon around our target stars. Our data set provides some insight into the occurrence rates of short-period planets around TRAPPIST-1-like stars, and our results can help test planetary formation and system evolution models, as well as guide future observations of nearby late-M dwarfs.
The Pantheon+ Analysis: Forward Modeling the Dust and Intrinsic Color Distributions of Type Ia Supernovae, and Quantifying Their Impact on Cosmological Inferences
Authors: Popovic Brodie , Brout Dillon , Kessler Richard , Scolnic Daniel 
Published: March 2023

Abstract
Recent studies have shown that the observed color distributions of Type Ia supernovae (SNe Ia) can be well described by a combination of a dust distribution and an intrinsic color distribution. Using the Pantheon+ sample of 1701 SN Ia, we apply a new forward-modeling fitting method (Dust2Dust) to measure the parent dust and color distributions, including their dependence on host-galaxy mass. At each fit step, the SN Ia selection efficiency is determined from a large simulated sample that is reweighted to reflect the proposed distributions. We use five separate metrics to describe the goodness of fit: distribution of fitted light-curve color c, cosmological residual trends with c, cosmological residual scatter with c, fitted color–luminosity relationship β
SALT2, and intrinsic scatter σ
int. We present the results and the uncertainty in 12-dimensional space. Furthermore, we measure that the uncertainty on this modeling propagates to an upper threshold uncertainty in the equation of state of dark energy w of 0.014(1) for the Pantheon+ cosmology analysis and contributes negligible uncertainty to the Hubble constant H
0. The Dust2Dust code is made publicly available at https://github.com/djbrout/dustdriver.
Fragmentation of the High-mass “Starless” Core G10.21-0.31: A Coherent Evolutionary Picture for Star Formation
Authors: Jiao Wenyu , Wang Ke , Pillai Thushara G. S. , Baug Tapas , Zhang Siju , Xu Fengwei 
Published: March 2023

Abstract
G10.21-0.31 is a 70 μm dark high-mass starless core (M > 300 M
⊙ within r < 0.15 pc) identified in the Spitzer, Herschel, and APEX continuum surveys, and is believed to harbor the initial stages of high-mass star formation. We present Atacama Large Millimeter/submillimeter Array (ALMA) and Submillimeter Array observations to resolve the internal structure of this promising high-mass starless core. Sensitive high-resolution ALMA 1.3 mm dust continuum emission reveals three cores of mass ranging within 11–18 M
⊙, characterized by a turbulent fragmentation. Cores 1, 2, and 3 represent a coherent evolution of three different stages, characterized by outflows (CO and SiO), gas temperature (H2CO), and deuteration (N2D+/N2H+). We confirm the potential for formation of high-mass stars in G10.21 and explore the evolution path of high-mass star formation. Yet, no high-mass prestellar core is present in G10.21. This suggests a dynamical star formation where cores grow in mass over time.
A New Hydrodynamic Spherical Accretion Exact Solution and Its Quasi-spherical Perturbations
Authors: Hernandez X. , Nasser L. , Aguayo-Ortiz A. 
Published: March 2023

Abstract
We present an exact γ = 5/3 spherical accretion solution that modifies the Bondi boundary condition of

ρ
→
constant

as r → ∞ to ρ → 0 as r → ∞. This change allows for simple power-law solutions on the density and infall velocity fields, ranging from a cold empty freefall condition where pressure tends to zero, to a hot hydrostatic equilibrium limit with no infall velocity. As in the case of the Bondi solution, a maximum accretion rate appears. As in the γ = 5/3 case of the Bondi solution, no sonic radius appears, this time however, because the flow is always characterized by a constant Mach number. This number equals 1 for the case of the maximum accretion rate, diverges toward the cold empty state, and becomes subsonic toward the hydrostatic equilibrium limit. It can be shown that in the limit r → 0, the Bondi solution tends to the new solution presented, extending the validity of the Bondi accretion value to cases where the accretion density profile does not remain at a fixed constant value out to infinity. We then explore small deviations from sphericity and the presence of angular momentum through an analytic perturbative analysis. Such perturbed solutions yield a rich phenomenology through density and velocity fields in terms of Legendre polynomials, which we begin to explore for simple angular velocity boundary conditions having zeros on the plane and pole. The new solution presented provides complementary physical insight into accretion problems in general.

Abstract
The identification of bright quasars at z ≳ 6 enables detailed studies of supermassive black holes, massive galaxies, structure formation, and the state of the intergalactic medium within the first billion years after the Big Bang. We present the spectroscopic confirmation of 55 quasars at redshifts 5.6 < z < 6.5 and UV magnitudes −24.5 < M
1450 < −28.5 identified in the optical Pan-STARRS1 and near-IR VIKING surveys (48 and 7, respectively). Five of these quasars have independently been discovered in other studies. The quasar sample shows an extensive range of physical properties, including 17 objects with weak emission lines, 10 broad absorption line quasars, and 5 objects with strong radio emission (radio-loud quasars). There are also a few notable sources in the sample, including a blazar candidate at z = 6.23, a likely gravitationally lensed quasar at z = 6.41, and a z = 5.84 quasar in the outskirts of the nearby (D ∼ 3 Mpc) spiral galaxy M81. The blazar candidate remains undetected in NOEMA observations of the [C ii] and underlying emission, implying a star formation rate <30–70 M
⊙ yr−1. A significant fraction of the quasars presented here lies at the foundation of the first measurement of the z ∼ 6 quasar luminosity function from Pan-STARRS1 (introduced in a companion paper). These quasars will enable further studies of the high-redshift quasar population with current and future facilities.
L’Anthropocène : un nouveau cadre de pensée pour la géographie scolaire ?
Authors: Joublot Ferré Sylvie 
Published: March 2023

Les décisions attendues des scientifiques de l’Anthropocene Working Group (AWG) pourraient attester officiellement d’une nouvelle époque géologique de la Terre : l’Anthropocène. D’ores et déjà les sciences sociales se sont largement emparées de ce nouveau paradigme. Pour la géographie, la discipline qui s’attache de manière privilégiée aux relations des humains à leur espace, quelles implications pourrait avoir cette reconnaissance ? Quel rôle la géographie scolaire peut-elle investir pour accompagner cette humanité devenue force géologique ? Il n’y aura pas une seule voie, mais incontestablement il y a une urgence.
Concilier l’inconciliable : l’enjeu de la transaction sociale en économie solidaire pour de nouvelles relations au monde
Authors: Stoessel-Ritz Josiane 
Published: March 2023

Ce texte en hommage à Jean Remy présente une lecture réflexive de moments marquants de ma biographie pour comprendre comment des liens se sont construits entre des préoccupations de recherche et l’inspiration produite par les travaux de J. Remy. Son œuvre dégage la cohérence d’ensemble d’une pensée qui concilie la complexité et l’unité et propose un cadre heuristique pour entrevoir de nouvelles perspectives abordées sous l’angle de trois expériences : la question paysanne, la coopération universitaire franco-algérienne, l’économie sociale et solidaire par la formation. La vision de Jean Remy donne un nouveau souffle à une sociologie des émergences ancrée dans la relation au monde.
La performativité du discours subsidiaire. Transactions communicationnelles dans un projet d’implantation d’un système d’information clinique
Authors: Cordelier Benoit 
Published: March 2023

À partir d’une recherche sur le déploiement d’un système de dossier patient numérique dans une organisation québécoise de santé et services sociaux, nous étudions, à partir de 48 entrevues semi-dirigées et une analyse documentaire, les tensions créées dans le projet de changement organisationnel que nous approchons comme un espace transactionnel. Nous relevons certains discours critiques à l’égard du déroulement du projet qui ne visent pas forcément à empêcher son aboutissement. Leur performativité limitée nous amène à proposer le concept de discours subsidiaire , autrement dit un discours accessoire, car il ne parvient pas à s’imposer et ne porte peut-être pas l’intention de le faire.
Analyse du processus de co-construction d’un centre social coopératif au prisme du paradigme de la transaction sociale
Authors: Bouadi Lamia 
Published: March 2023

Pour notre recherche doctorale, nous avons suivi dans la ville de Saint-Denis (93) la dynamique de préfiguration d’un projet de centre social avec le statut inédit de Société coopérative d’intérêt collectif (SCIC) qui, contrairement aux traditions des Centres sociaux, n’est ni autonome (associatif), ni dépendant (municipal), ni social (guichet de prise en charge), mais partenarial (municipalité, associations, habitants) et entrepreneurial. Ce projet bouscule les pratiques traditionnelles en matière de prestation de services aux habitants et se construit dans la conflictualité : ce projet s’adosse à des dynamiques invisibles par les habitant.e.s et à des encouragements à la co-construction par les pouvoirs publics et la société civile. Le paradigme de la transaction sociale se révèle pertinent pour comprendre les enjeux importants dans ces séquences de négociation, d’échange et de compromis dans cette innovation sociale en France.
Contrefaçons, impostures et usurpations. Enquête sur les factums du premier XIX e siècle
Authors: Yvernault Virginie 
Published: March 2023

À partir de l’exemple de trois affaires judiciaires, cet article étudie les factums du début du xix e siècle comme une forme polyvalente, dont l’écriture et les usages s’inscrivent dans un espace politique et médiatique, où les pratiques judiciaires dialoguent avec les pratiques littéraires. Ces mémoires se font l’écho des normes et des valeurs issues de la culture politique révolutionnaire, visant à renforcer les nouveaux droits alloués aux individus (propriété des auteurs, citoyenneté…). Alors que la réforme du système judiciaire était l’un des thèmes de prédilection des factums des décennies pré-révolutionnaires, celle-ci n’est plus une préoccupation majeure des mémoires imprimés du premier xix e siècle qui apparaissent moins comme un instrument de contestation politique que comme un moyen d’appropriation individuelle d’un nouvel ordre social et juridique.
« Quand plaideurs et accusés escaladaient le Parnasse ». Histoire de la défense en vers (XIX e siècle-années 1930)
Authors: Demartini Anne-Emmanuelle 
Published: March 2023

L’article aborde la question du « droit comme littérature » en traitant de la défense en vers dans les tribunaux français au xix e siècle. À partir d’un corpus documentaire élargi, il propose des éclairages neufs sur cette pratique insolite qui se révèle plus importante que prévu. Née sous la Restauration, elle traverse tout le siècle et se maintient jusqu’aux années 1930. Mais ses acteurs, sa signification et les réactions qu’elle suscite se modifient. Jusqu’aux années 1850, elle est marquée par une étroite solidarité entre poésie et politique, ce qui explique qu’elle puisse susciter la ferveur. Mais la figure du poète engagé dans la défense de la liberté d’expression cède ensuite la place au délinquant : la défense en vers se dépolitise tandis que les journaux y voient une expression des bas-fonds et tournent en dérision ces prouesses d’audience, illustrant la séparation croissante des espaces du vers et de la prose.
Évaluation de situations de maltraitance par de jeunes athlètes

Published: March 2023

Les adolescent·e·s font fréquemment face à des situations de violence interpersonnelle lors de la pratique d’un sport, et celles-ci restent encore souvent peu ou pas détectées dans le monde sportif. Cela peut s’expliquer par la priorité accordée à la performance sur l’intégrité physique, par la croyance à l’idée de no pain no gain , ou par la multiplexité de la relation entre le coach et l’athlète. Cette étude se base sur And You…? qui est une activité immersive originale permettant d’évaluer la perception de diverses situations de maltraitance à partir de cinq extraits de films grand public. Les données analysées ont été récoltées auprès de 203 jeunes athlètes sur le site des Jeux olympiques de la jeunesse à Lausanne et Saint-Moritz en Suisse en 2020. Les résultats montrent des réactions contrastées, mais homogènes face aux situations présentées. Ces différences s’expliquent en partie du fait que les violences sont hiérarchisées, les abus physiques étant plus sévèrement sanctionnés que les maltraitances psychologiques. On observe également qu’une situation est perçue comme davantage condamnable lorsque plusieurs types de violence sont exercés simultanément. Un autre facteur est celui de l’intériorisation de la violence, qui serait normalisée car perçue comme partie intégrante de la voie vers l’excellence. Finalement, on constate que les violences psychologiques à caractère sexuel sont aussi durement condamnées par les femmes que par les hommes, signe possible d’un changement normatif à ce propos.

Published: March 2023

Background and Objective:
Postoperative pain is frequently reported following scleral buckle (SB) surgery. This study assessed the efficacy of perioperative dexamethasone on postoperative pain and opioid use following SB.

Materials and Methods:
Forty-five patients with rhegmatogenous retinal detachments undergoing SB or SB and pars plana vitrectomy were randomly assigned to either standard care of postoperative oral acetaminophen and oxycodone/acetaminophen as needed or standard care plus 8 mg single-dose peri-operative intravenous dexamethasone. A questionnaire was administered on postoperative days 0, 1, and 7 to determine visual analog scale 0 to 10 pain score and number of opioid tablets consumed.

Results:

Mean visual analog scale score and opioid use were significantly lower in the dexamethasone group on postoperative day 0 compared with control (2.76 ± 1.96 vs 5.64 ± 3.40,
P
= 0.002; 0.41 ± 0.92 vs 1.34 ± 1.43,
P
= 0.016). The dexamethasone group also demonstrated significantly lower total opioid use (0.97 ± 1.88 vs 3.69 ± 5.32,
P
= 0.047). No significant differences in pain score or opioid use were observed on days 1 or 7 (
P
= 0.078;
P
= 0.311;
P
= 0.326;
P
= 0.334).

Conclusion:
Single-dose intravenous dexamethasone following SB can significantly reduce postoperative pain and opioid use.

100 let delovanja Zveze geografov Slovenije (1922–2022)
Authors: Smrekar Aleš , Pelc Stanko , Urbanc Mimi , Kunaver Jurij 
Published: March 2023

Osnovni namen prispevka je orisati zgodovino geografske stanovske organiziranosti. Začetki segajo v leto 1922, ko so slovenski študentje geografije ustanovili študentsko geografsko društvo, ki je kmalu preraslo študentske okvire in postalo društvo vseh slovenskih geografov. V sto letih svojega delovanja se je v skladu z zakonodajo nekajkrat preoblikovalo; tako je v osemdesetih letih dvajsetega stoletja nastala Zveza geografskih društev Slovenije in ob izteku prvega desetletja 21. stoletja Zveza geografov Slovenije, v okviru katere deluje 6 društev. Geografsko stanovsko organizacijo so vodili 2 predsednici in 16 predsednikov. Osrednje dejavnosti obsegajo izdajanje Geografskega vestnika (od leta 1925 94 letnikov) in Geografskega obzornika (od leta 1954 69 letnikov) ter organizacija 23 zborovanj slovenskih geografov (od leta 1952) ter številnih drugih dogodkov. Te dejavnosti so uresničevale temeljno poslanstvo, to je razvoj znanstvene in šolske geografije ter krepitev njene prepoznavnosti tako v domačem okolju kot tudi širše. //
One hundred years of the Association of Slovenian Geographers (1922–2022)
This article outlines the history of geography as professional organized activity in Slovenia. Its beginnings date back to 1922, when Slovenian geography students founded the student Geographical Society, which soon outgrew its student framework and became a society for all Slovenian geographers. During the hundred years of its existence, this organization was transformed several times in accordance with legislation; thus, in the 1980s, the Association of Slovenian Geographical Societies was formed, and in 2008 the Association of Slovenian Geographers, in which six societies are active. This professional organization has been led by eighteen presidents. Its activities include publishing the journals Geografski vestnik (Geographical Bulletin; ninety-four volumes since 1925) and Geografski obzornik (Geographic Review; sixty-ninth volumes since 1954), holding conferences (twenty-three since 1952), and many other events. These activities have accomplished its basic mission: developing geography research and education, and strengthening the profile of geography both in Slovenia and beyond.

V poglavju o gozdnih požarih v Sloveniji v obdobju 1995–2019 predstavimo njihovo prostorsko, časovno in velikostno razporeditev in pojavljanje, ki ga pojasnimo z lastnim meteorološkim požarnim indeksom. Posebej obravnavamo sto največjih požarov in opisujemo njihove temeljne značilnosti, kot so velikost, vzroki in vremenske razmere. V zadnjem delu podajamo pregled temeljnih izzivov pri upravljanju požarne nevarnosti in ogroženosti ter izpostavljamo področja, na katerih bi bilo smiselno uvesti ali nadaljevati preventivno ukrepanje. //
Large forest fires in Slovenia
This article presents the basic characteristics of large wildfires, for which the term ‘forest fire’ has become common in Slovenian. The introduction discusses their frequency and geographical distribution, focusing on southern Europe and southern Slovenia, after which the characteristics of large fires, also called ‘megafires’, are explained. The section on forest fires in Slovenia presents their spatial, time and size characteristics for the period from 1995 to 2019 and explains their occurrence with the author’s own meteorological fire index. The hundred largest fires are treated separately, describing the characteristics that distinguish them from smaller fires. The last part provides an overview of the basic challenges in managing fire hazard and risk, highlighting areas where it would be useful to introduce or continue preventive measures.
Immunogen-Specific Strengths and Limitations of the Activation-Induced Marker Assay for Assessing Murine Antigen-Specific CD4+ T Cell Responses

Abstract
The activation-induced marker (AIM) assay is a cytokine-independent technique to identify Ag-specific T cells based on the upregulated expression of activation markers after Ag restimulation. The method offers an alternative to intracellular cytokine staining in immunological studies, in which limited cytokine production makes the cell subsets of interest difficult to detect. Studies of lymphocytes in human and nonhuman primates have used the AIM assay to detect Ag-specific CD4+ and CD8+ T cells. However, there is a lack of validation of the strengths and limitations of the assay in murine (Mus musculus) models of infection and vaccination. In this study, we analyzed immune responses of TCR-transgenic CD4+ T cells, including lymphocytic choriomeningitis virus–specific SMARTA, OVA-specific OT-II, and diabetogenic BDC2.5-transgenic T cells, and measured the ability of the AIM assay to effectively identify these cells to upregulate AIM markers OX40 and CD25 following culture with cognate Ag. Our findings indicate that the AIM assay is effective for identifying the relative frequency of protein immunization–induced effector and memory CD4+ T cells, whereas the AIM assay had reduced ability to identify specific cells induced by viral infection, particularly during chronic lymphocytic choriomeningitis virus infection. Evaluation of polyclonal CD4+ T cell responses to acute viral infection demonstrated that the AIM assay can detect a proportion of both high- and low-affinity cells. Together, our findings indicate that the AIM assay can be an effective tool for relative quantification of murine Ag-specific CD4+ T cells to protein vaccination, while demonstrating its limitations during conditions of acute and chronic infection.
