Authors: Aponte Kevin O. Díaz , Xu Yanan , Rana Mukti 
Published: April 2023

The rapid expansion of the applications of infrared (IR) sensing in the commercial market has driven the need to develop new materials and detector designs for enhanced performance. In this work, we describe the design of a microbolometer that uses two cavities to suspend two layers (sensing and absorber). Here, we implemented the finite element method (FEM) from COMSOL Multiphysics to design the microbolometer. We varied the layout, thickness, and dimensions (width and length) of different layers one at a time to study the heat transfer effect for obtaining the maximum figure of merit. This work reports the design, simulation, and performance analysis of the figure of merit of a microbolometer that uses GexSiySnzOr thin films as the sensing layer. From our design, we obtained an effective thermal conductance of 1.0135×10−7 W/K, a time constant of 11 ms, responsivity of 5.040×105 V/W, and detectivity of 9.357×107 cm−Hz1/2/W considering a 2 μA bias current.

An increasing amount of evidence suggests the emerging role of the gut microbiota in the development of colorectal cancer (CRC). This study aimed to elucidate the architecture of microbial communities within normal and neoplastic colonic mucosa. Methods: Microbiota were analyzed by NGS and by an ensemble of metagenomics analysis tools in a total of 69 tissues from 9 patients with synchronous colorectal neoplasia and adenomas (27 specimens: 9 from normal tissues, 9 adenomas, and 9 tumours), 16 patients with only colonic adenomas (32 specimens: 16 from normal tissues and 16 adenomas), and from healthy subjects (10 specimens of normal mucosa). Results: Weak differences were observed in alpha and beta metrics among the synchronous tissues from CRC and controls. Through pairwise differential abundance analyses of sample groups, an increasing trend of Rikenellaceae, Pseudomonas and Fusobacterium, and decreasing trends of Staphylococcus, Actinobacillus and Gemmiger were observed in CRC, while Staphylococcus and Bifidobacterium were decreased in patients with only adenomas. At RT-qPCR analysis, Fusobacterium nucleatum was significantly enriched in all the tissues of subjects with synchronous colorectal neoplasia. Conclusion: Our findings provide a comprehensive view of the human mucosa-associated gut microbiota, emphasizing global microbial diversity mostly in synchronous lesions and proving the constant presence of Fusobacterium nucleatum, with its ability to drive carcinogenesis.

Background: Candida parapsilosis is the most common non-albicans candida species that causes invasive candidiasis, but little is known about its impacts on the outcomes of pediatric patients. We aimed to characterize the clinical characteristics, risk factors and outcomes of C. parapsilosis bloodstream infections (BSIs) in children. Methods: All pediatric patients with Candida parapsilosis BSIs between 2005 and 2020 from a medical center in Taiwan were enrolled and analyzed. The antifungal susceptibility, clinical manifestations, management and outcomes were investigated. Cases of Candida parapsilosis BSIs were compared between patients with C. albicans BSIs and other Candida spp. BSIs. Results: During the study period, 95 episodes (26.0% of total cases) of Candida parapsilosis BSIs were identified and analyzed. No significant difference was found between pediatric patients with C. parapsilosis BSIs and those with C. albicans BSIs in terms of patients’ demographics, most chronic comorbidities or risk factors. Pediatric patients with C. parapsilosis BSIs were significantly more likely to have previous azole exposure and be on total parenteral nutrition than those with C. albicans BSIs (17.9 vs. 7.6% and 76.8 vs. 63.7%, p = 0.015 and 0.029, respectively). The duration of C. parapsilosis candidemia was relatively longer, and therefore patients often required a longer duration of antifungal treatment when compared with those of C. albicans candidemia, although the candidemia-attributable mortality rates were comparable. Of the C. parapsilosis isolates, 93.7% were susceptible to all antifungal agents, and delayed appropriate antifungal treatment was an independent factor in treatment failure. Conclusions: Pediatric patients with C. parapsilosis BSIs were more likely to have previous azole exposure and be on total parenteral nutrition, and the clinical significances included a longer duration of candidemia and patients often required a longer duration of antifungal treatment.

The mode and mechanism of diabetic periodontitis-induced alveolar-osteocyte death are still unclear. This study aimed to investigate the occurrence of ferroptosis in alveolar osteocytes during diabetic periodontitis and the therapeutic potential of resveratrol to alleviate osteocyte ferroptosis. Diabetic periodontitis was induced in C57/BL6-male mice and treated with or without resveratrol. Periodontitis pathogenicity was analyzed by micro-CT and histology, and alveolar-osteocyte ferroptosis was analyzed by immunohistochemistry. MLOY4 osteocytes were treated with P. gingivalis-derived lipopolysaccharide (LPS)+advanced glycosylated end products (AGEs) mimicking diabetic periodontitis condition in vitro, with or without resveratrol or ferrostatin-1 (ferroptosis inhibitor). Osteocyte ferroptosis and expression of inflammatory mediators were analyzed. Diabetic periodontitis aggravated periodontitis pathogenicity and inhibited the expression of GPX4 and SLC7A11 in alveolar osteocytes and resveratrol alleviated these effects. LPS+AGEs triggered osteocyte ferroptosis in vitro as indicated by the downregulated GPX4 and SLC7A11, upregulated malondialdehyde, disrupted mitochondrial morphology, and overexpressed pro-inflammatory mediators IL-1β, TNF-α, SOST, RANKL, and IL-6, and ferrostatin-1 or resveratrol treatment reversed these effects. LPS+AGEs upregulated pIKBα and pNF-κB p65 expression in osteocytes, and resveratrol or ferrostatin-1 reversed this effect. In conclusion, diabetic periodontitis triggers alveolar osteocyte ferroptosis possibly via disruption of the SLC7A11/GPX4 axis, and resveratrol has therapeutic potential to correct this biological event.

In this quick study, we estimated the Weibull distribution’s parameters using wind data collected between March 2017 and January 2018 using a twelve-meter mast meteorological station on the grounds of the National Energy Research Center in Khartoum. In order to quantify these descriptors, we relied on analytical and stochastic methods, subsequently enabling specialists from researchers, engineers, decision-makers, and policymakers to apprehend the wind characteristics in the vicinity. Hence, the computed scale and shape parameters were provided, in which the Firefly algorithm (FA) resulted in the most accuracy in terms of the coefficient of determination, which equaled 0.999, which we considered logical due to the observed nonlinearity in the wind speed numbers. On the contrary, the energy pattern factor method had the worst prediction capability depending on several goodness-of-fit metrics. This concise work is unique because it is the first to use data from Sudan to forecast local wind speeds using artificial intelligence algorithms, particularly the FA technique, which is widely used in solar photovoltaic modeling. Additionally, since classic estimating approaches act differently spatially, evaluating their efficacy becomes innovative, which was accomplished here. On a similar note, a weighted-average wind speed was found to equal 4.98 m/s and the FA average wind speed was 3.73 m/s, while the rose diagram indicated that most winds with potential energy equivalent to 3 m/s or more blow from the north.

Published: April 2023

Abstract
Galaxy evolution can be dramatically affected by the environment, especially by the dense environment of a galaxy cluster. Recent observational studies show that massive galaxies undergoing strong ram-pressure stripping (RPS) have an enhanced frequency of nuclear activity. We investigate this topic using a suite of wind-tunnel hydrodynamical simulations of a massive M
star = 1011
M
⊙ disk galaxy with 39 pc resolution and including star formation and stellar feedback. We find that RPS increases the inflow of gas to the galaxy center regardless of the wind impact angle. This increase is driven by the mixing of interstellar and nonrotating intracluster media at all wind angles, and by increased torque on the inner disk gas, mainly from local pressure gradients when the intracluster medium (ICM) wind has an edge-on component. In turn, the strong pressure torques are driven by rising ram pressure. We estimate the black hole (BH) accretion using Bondi–Hoyle and torque models, and compare it with the mass flux in the central 140 pc region. We find that the torque model predicts much less accretion onto the BH of a RPS galaxy than the Bondi–Hoyle estimator. We argue that both models are incomplete: the commonly used torque model does not account for torques caused by the gas distribution or local pressure gradients, while the Bondi–Hoyle estimator depends on the sound speed of the hot gas, which includes the ICM in stripped galaxies. An estimator that accounts for this missing physics is required to capture BH accretion in a RPS galaxy.
Asteroseismic Determination of Stellar Rotation: On Synchronization in the Close Eclipsing Binaries AB Cas and OO Dra
Authors: Kim Seung-Lee 
Published: April 2023

Abstract
A star’s rotation rate is difficult to estimate without surface inhomogeneities such as dark or bright spots. This paper presents asteroseismic results to determine the rotation rates of δ Sct-type pulsating primary stars in two eclipsing binary systems, AB Cas and OO Dra. After removing the binarity-induced light variations from archival TESS data and carefully examining the combination frequencies, we identified 12 independent frequencies for AB Cas and 11 frequencies for OO Dra, with amplitudes higher than ∼0.3 mmag, as δ Sct-type pulsation frequencies excited in each primary star. The theoretical frequencies for seismic analysis were obtained by fully considering rotation effects. Grid fitting for various stellar properties, such as mass, radius, metallicity, and rotation rate, yielded the best solutions for which the theoretical frequencies and stellar parameters agreed well with the observations. The rotation rate of the AB Cas primary was tightly constrained to 0.81 ± 0.01 day−1 (f
rot/f

), which is slightly faster than the synchronized rotation. In contrast, the rotation rate of 0.63 ± 0.01 day−1 for the OO Dra primary is lower than the synchronous value of approximately 0.81 day−1. Subsynchronous rotation is uncommon in short-period binaries, and its physical mechanism is not yet well understood. Our results show that asteroseismology can be used to measure the rotation rate of fast-rotating δ Sct stars precisely and thus provide a valuable constraint on rotation–orbit synchronization in close binary systems.

Entre aides et entraides. Enquête sur les expédients alimentaires de trois personnes immigrées sans-domicile
Authors: Renoux Paolo 
Published: April 2023

Cet article s’appuie sur une enquête de l’Observatoire du Samusocial de Paris, « Hors-Service », portant sur les manifestations socio-économiques de la crise sanitaire de Covid-19 sur les personnels du secteur de l’hôtellerie-restauration, et menée en 2020 et 2021. Les budgets de trois personnes sans domicile y sont étudiés dans une perspective ethnocomptable sous l’angle spécifique de l’alimentation. La description des économies domestiques met en lumière tout un panel d’activités, de ressources et de relations sociales qui s’articulent pour former un équilibre budgétaire. Au sein de ces portefeuilles de subsistance, le recours à l’aide alimentaire côtoie de multiples façons de se nourrir à moindre coût. L’aide d’urgence ne remplit pas toujours le même rôle, pouvant paradoxalement devenir vectrice d’indépendance et d’émancipation alimentaire. L’enquête met en évidence les usages et les enjeux multiples de l’alimentation qui, loin de se réduire à son intérêt nutritionnel et à ses implications économiques, s’inscrit dans la recherche d’une vie, sociale et domestique, qui vaut la peine d’être vécue. L’étude des budgets, ici ceux de l’alimentation, déborde largement la question économique pour permettre une compréhension fine du vécu des personnes sans domicile, de leurs évaluations quotidiennes et de leurs horizons biographiques.
L’hébergement d’urgence à l’épreuve de la pandémie. Enquête sur les reconfigurations d’un dispositif de mise à l’abri hivernal

Published: April 2023

Cet article analyse les transformations de l’hébergement d’urgence dans le cadre de la pandémie du Covid-19 et les épreuves qu’elles ont engendrées pour les professionnels et les personnes qui y sont hébergées. À partir d’une enquête de terrain conduite dès le premier confinement en mars 2020 et prolongée jusqu’en mars 2022, nous documentons comment un dispositif de « mise à l’abri hivernal » a fait l’objet de reconfigurations afin de mettre en application les mesures de « confinement » et de « distanciation sociale ». Alors que la promiscuité de ce type d’hébergement est déjà connue, nous montrons que celle-ci est désormais cadrée comme un problème sanitaire. Ce nouveau cadrage engendre des pratiques d’espacements et de déplacements de personnes vers d’autres habitats précaires, dont l’internat d’un lycée. En décrivant ces espacements et déplacements des personnes hébergées, l’enquête montre comment la crise sanitaire a finalement contribué à renforcer l’intensité de deux épreuves typiques de l’urgence sociale : celle du déplacement contraint des individus considérés sans attaches et celle du caractère temporaire et précaire des habitats proposés.

Une censure éditoriale : Ravages de Violette Leduc
Authors: Antolin Alexandre 
Published: April 2023

En 1948, lorsque Violette Leduc commence à rédiger Ravages, roman autobiographique, elle ne sait pas qu’elle se lance dans l’œuvre de toute une vie. Si les premiers conseils prodigués par Simone de Beauvoir sont exigeants mais bienveillants, les relectures des éditions Gallimard sont bien plus sévères. Dans une société qui refuse certaines réalités et où la Commission de censure exerce un pouvoir fort, les scènes d’amour lesbien, de viol ou d’avortement inquiètent la maison d’édition, qui demande à l’autrice d’effectuer de larges coupes. En 1955, l’ouvrage sort enfin aux éditions Gallimard, mais il est amputé d’une grande partie de ce qui fait son identité. Par la suite, certains extraits du texte censuré paraissent ici et là, mais sans jamais redonner sa force et son entièreté à cette œuvre majeure de la littérature française. À travers l’analyse génétique minutieuse des différentes versions de Ravages – manuscrits, dactylographies, textes publiés –, mais aussi de tous les écrits qui l’accompagnent, Alexandre Antolin retrace le parcours littéraire, psychologique et médiatique de Violette Leduc. Il permet également d’appréhender l’œuvre intégrale non censurée et d’en découvrir toute la richesse.
Adverse Childhood Experiences and Burnout in Athletic Trainers: An Exploratory Study
Authors: Hedrick Alexander , Lynch Amy , Russ Anne C. 
Published: April 2023

Context
Burnout, a state of physical or emotional exhaustion, is a concern within athletic training, as between 17% and 40% of athletic trainers (ATs) report high levels of burnout. Adverse childhood experiences (ACEs) are linked with higher levels of burnout in other health professions.

Objective
To compare burnout with ACEs in ATs.

Design
Cross-sectional study.

Setting
Web-based survey.

Patients or Other Participants
One thousand ATs were selected at random to participate in the study. Of these, 78 ATs started the survey, and 75 ATs completed it.

Main Outcome Measure(s)
Burnout, as measured by the Copenhagen Burnout Inventory (CBI) overall and subscale scores, was compared across groups based on the number of adverse experiences as measured by the ACEs survey. Multiple analysis of variance tests were used to determine the association between ACEs score and overall, personal, work-related, and patient-related burnout.

Results
At least 1 adverse experience was reported by 37 (49.33%) participants. Those with ≥4 ACEs had higher odds of describing overall, personal, and work-related burnout than those with 0 to 3 ACEs. Moderate burnout (CBI score ≥ 50.00) was noted in 27 (36.00%, overall), 44 (58.67%, personal), 34 (45.3%, work related), and 15 (20.00%, patient related) ATs. Participants with 4 ACEs had higher overall burnout (67.11 ± 19.89; F6,68 = 2.59, P = .03) than those with 0 (40.53 ± 17.12, P = .04), 1 (38.42 ± 20.99, P = .04), or 7 (19.08 ± 12.09, P = .03) ACEs. The same pattern existed with personal burnout, as participants with 4 ACEs (76.67 ± 17.33) had higher scores (F6,68 = 3.40, P = .00) than those with 0 (46.60 ± 17.49, P = .02), 1 (42.78 ± 21.48, P = .01), or 7 (27.08 ± 20.62, P = .03) ACEs. No other differences were observed.

Conclusions
Between 20.00% and 58.67% of ATs surveyed reported some form of burnout. Higher levels of overall and personal burnout were found in those with 4 ACEs. Although we expected to see lower levels of burnout in those with fewer ACEs, it was surprising that those with 7 ACEs had some of the lowest CBI scores. Athletic trainers with childhood trauma may find it beneficial to engage in self-regulation exercises to reduce or limit triggers and burnout. Additionally, employers should explore developing trauma-informed workplaces to better support employees.
Infection index

Published: April 2023

BackgroundChronic obstructive pulmonary disease (COPD) is a chronic debilitating disease. Acute exacerbation of COPD (AECOPD) determines the extent of disease morbidity, healthcare utilization, associated costs, and mortality. Patients with COPD who have chronic colonization would not only have greater burden of inflammation and more frequent exacerbations but also a faster decline in pulmonary functions. Hence, our study was conducted.Patients and methodsA total of 125 patients were enrolled in this cross-section study, which was conducted at Chest Department and Respiratory ICU. Laboratory analysis of the study samples was performed in Medical Microbiology and Clinical Pathology Departments, Faculty of Human Medicine, Zagazig University Hospitals, in the period between May 2018 and July 2019.ObjectiveThe aim was to examine the value of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) as a promising inflammatory biomarker in detecting chronic bacterial colonization and to settle the cutoff value for the suggested infection index in identifying bacterial colonization. Results Based on sputum culture results, patients were classified into two groups: group A (those with bacterial colonizers) and group B (those with no bacterial colonizers). All assessed laboratory tests were significantly higher in patients with exacerbated COPD with bacterial colonization.ConclusionsTREM-1 is a valid and reliable inflammatory biomarker and can determine the presence of chronic bacterial colonizers. Infection index (procalcitonin+sTREM-1) should be applied and measured for admitted AECOPD with exacerbations of noninfective type, and this would guide antibiotic usage and limit overutilization of antibiotics in noninfective patients with AECOPD.
