Étude Géologique de la partie septentrionale du Plateau de Millevaches
Authors: Masclanis Paul 
Published: January 2025

La partie septentrionale du Plateau de Millevaches est essentiellement formée de granulites au milieu desquelles se présentent de grandes masses de granités migmatitiques. On observe, soit un passage continu d’un massif à l’autre, soit, surtout au Nord, un contact intrusif net de la granulite dans le granité. Au sein des granulites. on trouve des migmatites à deux micas en septa allongés suivant le contour des massifs de granulite. Les granites migmatitiques sont sans muscovite, et forment un grand massif à contour dentelliforme contenant des passages locaux à des migmatites ou des enclaves de gneiss à biotite. Cette masse de migmatites est vraisemblablement en relation avec la mise en place du magma granulitique qui s'est fait en étapes successives. Des micaschistes anciens apparaissent sur les bords de la granulite. ils sont alors concordants avec elle, ou en septa-internes.
Le tout forme, im anticlinal déversé vers l’Est, entouré de failles.
Le Chuquet Genestoux et les projections palagonitiques du rraar d'Enval
Authors: Camus Guy , Vincent Pierre Marcel 
Published: January 2025

Des projections pal agoni tiques découvertes récemment près d'Enval présentent tous les caractères d'un dépôt de maar. Le cratère qui les a émises avait un diamètre de l'ordre de 700 mètres ; il est aujourd'hui fortement oblitéré par les coulées descendues du secteur du Puy de Dôme. Une petite bouche adventive a projeté simultanément des laves très fluides érigeant le cône de scories soudées très particulier du Chuquet Genestoux.
Les projections du maar d'Enval et du Chuquet Genestoux renferment un cortège d'enclaves mono et polyminérales (grandes amphiboles, scapolites, nodules de péridotites) qui parait assez fréquent dans ce type de volcanisme.

Les sapinières disparues et actuelles sur tourbe du Massif Central français
Authors: Lemée Georges 
Published: January 2025

Fir (Abies alba) that presently edges peat bogs enter them in the North of Forez mountains, in "Les Bois Noirs"
and "Monts de la Madeleine" where they form a community showing abundant peat mosses (Sphagnum) and characteristic species of spruce (Picea abies) forest stands. The observed persistance of birch (Betula pubescens) in this semi-open community leads to suggest the name of Betulo-Abietetum, as a part of the Vaccinio-Abietenion under-alliance.
In other respects, large remains of fir where found in peaty areas in Massif central, in layers dating back to Subboreal. These stands are located along a bowed line from North-East of Cantal to West of monts Dore, with isolated sites in Aubrac, base of Mezenc and Pilat mounts. In these sites, fir (even sometimes forest) have already disappeared. Since the observed presence of fir in peat bogs is often linked with an early emergence, one can suggest that this species spread from Alps or North Vivarais (it was present there since the Atlantic period), seeds being transported by birds. In certain sites, the pollinie abundance of fir, equal or even lower to that of beech, indicates that fir was present on peaty area only.

Published: January 2025

Sepsis-associated encephalopathy (SAE) is a severe and frequent septic complication, characterized by neuronal damage as key pathological features. The astrocyte–microglia crosstalk in the central nervous system (CNS) plays important roles in various neurological diseases. However, how astrocytes interact with microglia to regulate neuronal injury in SAE is poorly defined. In this study, we aim to investigate the molecular basis of the astrocyte–microglia crosstalk underlying SAE pathogenesis and also to explore the new therapeutic strategies targeting this crosstalk in this devastating disease. We established a human astrocyte/microglia coculture system on a microfluidic device, which allows real-time and high-resolution recording of glial responses to inflammatory stimuli. Based on this microfluidic system, we can test the responses of astrocytes and microglia to lipopolysaccharide (LPS) treatment, and identify the molecular cues that mediate the astrocyte–microglia crosstalk underlying the pathological condition. In addition, the SAE mouse model was utilized to determine the state of glial cells and evaluate the therapeutic effect of drugs targeting the astrocyte–microglia crosstalk in vivo. Here, we found that activated astrocytes and microglia exhibited close spatial interaction in the SAE mouse model. Upon LPS exposure for astrocytes, we detected that more microglia migrated to the central astrocyte culture compartment on the microfluidic device, accompanied by M1 polarization and increased cell motility in microglia. Cytokine array analysis revealed that less interleukin 11 (IL11) was secreted by astrocytes following LPS treatment, which further promoted reprogramming of microglia to pro-inflammatory M1 phenotype via the nuclear factor-κB (NF-κB) signaling pathway. Intriguingly, we found that IL11 addition markedly rescued LPS-induced neuronal injuries on the microfluidic system and brain injury in the SAE mouse model. This study defines an unknown crosstalk of astrocyte–microglia mediated by IL11, which contributed to the neuropathogenesis of SAE, and suggested a potential therapeutic value of IL11 in the devastating disease.

The cost of perspective switching: Constraints on simultaneous activation
Authors: Segal Dorit 
Published: January 2025

Abstract
Visual perspective taking often involves transitioning between perspectives, yet the cognitive mechanisms underlying this process remain unclear. The current study draws on insights from task- and language-switching research to address this gap. In Experiment 1, 79 participants judged the perspective of an avatar positioned in various locations, observing either the rectangular or the square side of a rectangular cube hanging from the ceiling. The avatar's perspective was either consistent or inconsistent with the participant’s, and its computation sometimes required mental transformation. The task included both single-position blocks, in which the avatar's location remained fixed across all trials, and mixed-position blocks, in which the avatar's position changed across trials. Performance was compared across trial types and positions. In Experiment 2, 126 participants completed a similar task administered online, with more trials, and performance was compared at various points within the response time distribution (vincentile analysis). Results revealed a robust switching cost. However, mixing costs, which reflect the ability to maintain multiple task sets active in working memory, were absent, even in slower response times. Additionally, responses to the avatar's position varied as a function of consistency with the participants' viewpoint and the angular disparity between them. These findings suggest that perspective switching is costly, people cannot activate multiple perspectives simultaneously, and the computation of other people's visual perspectives varies with cognitive demands.

KSP-SCOS: new Karp-Steele patching based streamlined customer order scheduling approach
Authors: Mekour Mansour , Houacine Abdelkrim , Mekkaoui Kheireddine 
Published: January 2025

Customer order scheduling (COS) encapsulates one of the most intricate problems in operational optimization, primarily due to the multifaceted interplay of constraints such as temporal dependencies, resource limitations, and cost minimization. This paper introduces the Karp-Steele Patching for Streamlined COS (KSP-SCOS), a cutting-edge framework designed to address these complexities with unparalleled precision and efficiency. By incorporating the dynamic problem decomposition capabilities of Karp-Steele Patching, KSP-SCOS enhances the scheduling landscape through systematic exploration of feasible solutions while eliminating suboptimal paths through strategic pruning. The proposed approach was subjected to rigorous testing across diverse datasets representing a broad spectrum of real-world operational scenarios. These scenarios range from minimally constrained environments to those characterized by extensive resource contention and tight scheduling windows. Experimental findings reveal that KSP-SCOS consistently delivers near-optimal solutions, demonstrating robust scalability and significant reductions in computational overhead, regardless of the problem complexity. This research makes several noteworthy contributions to COS optimization : (1) The integration of the Karp-Steele Patching method within COS, ensuring a systematic yet adaptable solution process. (2) An empirical analysis across datasets of varying complexity, illustrating the algorithm’s effectiveness in balancing computational efficiency and scheduling quality. (3) An exploration of cost-time trade-offs, shedding light on the practical implications of for resource allocation in dynamic operational settings. The adaptability of KSP-SCOS establishes it as a groundbreaking for industries demanding dynamic, accurate, and resource-efficient scheduling strategies. Its capability to seamlessly adjust to evolving operational constraints underscores its critical relevance in scenarios requiring immediate and responsive decision-making. This study marks a pivotal advancement in resolving the pressing challenges of modern COS, paving the way for elevated operational efficacy and adaptability in increasingly complex environments.
H2 Chemistry and Protonation in the Dayside Venusian Upper Atmosphere
Authors: Wu Shiqi , Wu Xiaoshu , Liu Yanxing , Cui Jun 
Published: January 2025

Abstract
Although H2 is present in low concentrations, it critically controls the structure and composition of planetary upper atmospheres through protonation under solar extreme-ultraviolet and soft X-ray irradiation. Recent studies highlight the importance of protonation on Venus. As H2 concentrations in its upper atmosphere remain poorly constrained, we conduct a systematic model investigation of how the structure of the topside Venusian ionosphere responds to varying H2 distributions. Our model results suggest that protonated species could outnumber nonprotonated species in the topside ionosphere when ambient H2 concentrations exceed 5 ppm. Generally, increasing H2 concentrations enhances the degree of protonation, manifesting as elevated levels of most protonated species, while nonprotonated species are generally depleted due to rapid reactions with H2. These trends, however, are not universal; nonmonotonic variations among multiple species like OH+ and O

emerge, driven by the complex chemical network that intricately links species distributions throughout the upper atmosphere. The results presented here provide a foundation for improved characterization of hydrogen escape on Venus during its evolutionary history.

Abstract
We present multifrequency (5–345 GHz) and multiresolution radio observations of 1ES 1927+654, widely considered one of the most unusual and extreme changing-look active galactic nuclei (CL-AGNs). The source was first designated a CL-AGN after an optical outburst in late 2017 and has since displayed considerable changes in X-ray emission, including the destruction and rebuilding of the X-ray corona in 2019–2020. Radio observations prior to 2023 show a faint and compact radio source typical of a radio-quiet AGN. Starting in 2023 February, 1ES 1927+654 began exhibiting a radio flare with a steep exponential rise, reaching a peak 60 times previous flux levels, and has maintained this higher level of radio emission for over a year to date. The 5–23 GHz spectrum is broadly similar to gigahertz-peaked radio sources, which are understood to be young radio jets less than ∼1000 yr old. Recent high-resolution Very Long Baseline Array observations at 23.5 GHz now show resolved extensions on either side of the core, with a separation of ∼0.15 pc, consistent with a new and mildly relativistic bipolar outflow. A steady increase in the soft X-ray band (0.3–2 keV) concurrent with the radio may be consistent with jet-driven shocked gas, though further observations are needed to test alternate scenarios. This source joins a growing number of CL-AGNs and tidal disruption events that show late-time radio activity, years after the initial outburst.
