« Land of the dead », « Land for the dead », « deadlands » : approches théoriques de l’espace dans les oeuvres de la zombie culture
Authors: Obadia Lionel 
Published: January 2025

À partir d’une analyse de corpus filmique, textuel et graphique, cet article entend discuter les différentes dimensions spatiales qui se déclinent dans les oeuvres de la zombie culture depuis les années 1960 ainsi que les frontières qu’elles établissent entre le monde des humains et celui des morts, entre les contextes urbain et rural, entre le cimetière et la ville, entre espace souterrain et espace terrestre, mais aussi, de manière plus oblique, entre minorités et majorité. Les morts-vivants nourrissent d’autres allégories, sociales, cette fois, à travers les ondulations de l’espace (notamment urbain), entre le vide et le saturé de présence, entre l’inclusion/exclusion spatiale des vivants et des morts. Étant très mobiles, ils font saillir, à l’image des vivants qu’ils chassent, un rapport complexe et très déterminant à l’espace.

Published: January 2025

Gamma-irradiation at doses of 10 kGy and 25 kGy was applied on walnuts in order to study changes in the fat yield, fatty acids composition, conjugated dienes and trienes, tocopherols and oxidative stability of the extracted glyceride oils. The results revealed no significant changes in fat yield and fatty acids composition but an increase of dienes and trienes, and a decrease in tocopherols amount. Decrease of Induction periods of oils autoxidated at 80 ⁰C, 100 ⁰C, and 120 ⁰C was observed as well. In order to reduce the negative effects of radiation-related lipid oxidation walnut oils were supplemented with binary antioxidant mixtures. Thus, the composition of ascorbyl palmitate and α-tocopherol in 2:1 ratio slightly prolonged the induction periods while halving of the initial oxidation rate of oils extracted from irradiated walnuts at the same time.

Child sexual abuse (CSA) is a serious human rights violation that affects hundreds of millions of children globally. This study aims to elucidate the fundamental dynamics in the reporting and diagnostic processes of intra-familial and extra-familial CSA cases in Turkey, as examined within the forensic medical system. The research is based on case files (n = 1421) from the Child Monitoring Centre (CMC) in Antalya, Turkey. The study identified 149 cases (10.5%) of intra-familial abuse and 1272 cases (89.5%) of extra-familial abuse. In the intra-familial group, the perpetrator was often the father, stepfather, or mother's boyfriend, whereas in the extra-familial group, the perpetrator was frequently a friend or boyfriend. Pregnancy was identified in 12.1% of intra-familial and 15.1% of extra-familial cases. Psychiatric disorders were diagnosed in 32.1% of the intra-familial group. The findings underscore the necessity for strengthened multidisciplinary centres, thorough evaluations, and follow-ups of all CSA cases, alongside mandatory psychiatric assessments to facilitate early detection and intervention.
Relationship between Temperature and the Magnetic Strength

Published: January 2025

The magnetic field will attract ferrous materials like iron or nickel. It also attracts or repels other magnets depending, on the polarity of the other magnets Permanent magnets are made from materials that will remain magnetized and are hence able to maintain the magnetic field around them continuously. The study aims at investigating the effect of temperature on the strength of magnets; emphasizing both the scientific and practical significance the work provides knowledge to undertand the properties of magnets of its strength when confronted with different temperatures. Once the results are achieved then further studies on permanent loss of magnetic performance on a magnet when heated above. Curie temperature will follow. The methodology is based on Observations on the effect of temperature on the strength of magnets were made. The deflections made on the compass needle on magnet heated at different temperatures from 25o C to 98o C were recorded. The general conclusions were the effects of the temperature to the rate of the pull of a magnet are inversely proportional. That is the temperature of a magnet increases, it becomes weaker and as the temperature of a magnet decreases, it becomes stronger.

Published: December 2023

ImportanceThe COVID-19 pandemic had unprecedented effects on hospital occupancy, with consequences for hospital operations and patient care. Previous studies of occupancy during COVID-19 have been limited to small samples of hospitals.ObjectiveTo measure the association between COVID-19 admission rates and hospital occupancy in different US areas and at different time periods during 2020.Design, Setting, and ParticipantsThis cross-sectional study used data from the Healthcare Cost and Utilization Project State Inpatient Databases (2019-2020) for patients in nonfederal acute care hospitals in 45 US states, including the District of Columbia. Data analysis was performed between September 1, 2022, and April 30, 2023.ExposuresEach hospital and week in 2020 was categorized based on the number of COVID-19 admissions per 100 beds (&amp;lt;1 [low], 1-4.9, 5-9.9, 10-14.9, or ≥15 [high]).Main Outcomes and MeasuresThe main outcomes were inpatient and intensive care unit (ICU) occupancy. We used regression analysis to estimate the average change in occupancy for each hospital-week in 2020 relative to the same hospital week in 2019.ResultsThis study included 3960 hospitals and 54 355 916 admissions. Of the admissions in the 40 states used for race and ethnicity analyses, 15.7% were for Black patients, 12.9% were for Hispanic patients, 62.5% were for White patients, and 7.2% were for patients of other race or ethnicity; 1.7% of patients were missing these data. Weekly COVID-19 admission rates in 2020 were less than 4 per 100 beds for 63.9% of hospital-weeks and at least 10 in only 15.9% of hospital-weeks. Inpatient occupancy decreased by 12.7% (95% CI, 12.1% to 13.4%) during weeks with low COVID-19 admission rates and increased by 7.9% (95% CI, 6.8% to 9.0%) during weeks with high COVID-19 admission rates. Intensive care unit occupancy rates increased by 67.8% (95% CI, 60.5% to 75.3%) during weeks with high COVID-19 admissions. Increases in ICU occupancy were greatest when weighted to reflect the experience of Hispanic patients. Changes in occupancy were most pronounced early in the pandemic. During weeks with high COVID-19 admissions, occupancy decreased for many service lines, with occupancy by surgical patients declining by 43.1% (95% CI, 38.6% to 47.2%) early in the pandemic.Conclusions and RelevanceIn this cross-sectional study of US hospital discharges in 45 states in 2020, hospital occupancy decreased during weeks with low COVID-19 admissions and increased during weeks with high COVID-19 admissions, with the largest changes occurring early in the pandemic. These findings suggest that surges in COVID-19 strained ICUs and were associated with large decreases in the number of surgical patients. These occupancy fluctuations may have affected quality of care and hospital finances.

AbstractHydrogen sulfide (H2S) is a gaseous inflammatory mediator and important signaling molecule for maintaining gastrointestinal (GI) homeostasis. Excess intraluminal H2S in the GI tract has been implicated in inflammatory bowel disease and neurodegenerative disorders; however, the role of H2S in disease pathogenesis and progression is unclear. Herein, an electrochemical gas‐sensing ingestible capsule is developed to enable real‐time, wireless amperometric measurement of H2S in GI conditions. A gold (Au) three‐electrode sensor is modified with a Nafion solid‐polymer electrolyte (Nafion‐Au) to enhance selectivity toward H2S in humid environments. The Nafion‐Au sensor‐integrated capsule shows a linear current response in H2S concentration ranging from 0.21 to 4.5 ppm (R2 = 0.954) with a normalized sensitivity of 12.4% ppm−1 when evaluated in a benchtop setting. The sensor proves highly selective toward H2S in the presence of known interferent gases, such as hydrogen (H2), with a selectivity ratio of H2S:H2 = 1340, as well as toward methane (CH4) and carbon dioxide (CO2). The packaged capsule demonstrates reliable wireless communication through abdominal tissue analogues, comparable to GI dielectric properties. Also, an assessment of sensor drift and threshold‐based notification is investigated, showing potential for in vivo application. Thus, the developed H2S capsule platform provides an analytical tool to uncover the complex biology‐modulating effects of intraluminal H2S.

AbstractIn two‐dimensional/three‐dimensional (2D/3D) perovskite heterostructure, randomly distributed multiple quantum wells (QW) 2D perovskites are frequently generated, which are detrimental to carrier transport and structural stability. Here, the high quality 2D/3D perovskite heterostructure is constructed by fabricating functional‐group‐induced single QW Dion–Jacobson (DJ) 2D perovskites. The utilization of ─OCH3 in the precursor solution facilitates the formation of colloidal particles with uniform size, resulting in the production of a pure 2D DJ perovskite with an n value of 3. This strategy facilitates the improvement of 3D structural stability and expedites carrier transport. The resultant devices accomplish a power conversion efficiency of 25.26% (certified 25.04%) and 23.56% at a larger area (1 cm2) with negligible hysteresis. The devices maintain >96% and >89% of their initial efficiency after continuous maximum power point tracking under simulated AM1.5 illumination for 1300 h and under damp‐heat conditions (85 °C and 85% RH) for 1010 h, respectively.

AbstractThe advent of Internet of Things and artificial intelligence era necessitates the advancement of self‐powered electronics. However, prevalent multifunctional electronics still face great challenges in rigid electrodes, stacked layers, and external power sources to restrict the development in flexible electronics. Here, a transparent, self‐healing, anti‐freezing (TSA) ionogel composed of fluorine‐rich ionic liquid and fluorocarbon elastomer, which is engineered for monolayered triboelectric nanogenerators (M‐TENG) and electromagnetic energy‐based touch panels is developed. Notably, the TSA‐ionogel exhibits remarkable features including outstanding transparency (90%), anti‐freezing robustness (253 K), impressive stretchability (600%), and repetitive self‐healing capacity. The resultant M‐TENG achieves a significant output power density (200 mW m−2) and sustains operational stability beyond 1 year. Leveraging this remarkable performance, the M‐TENG is adeptly harnessed for biomechanical energy harvesting, self‐powered control interface, electroluminescent devices, and enabling wireless control over electrical appliances. Furthermore, harnessing Faraday's induction law and exploiting human body's intrinsic antenna properties, the TSA‐ionogel seamlessly transforms into an autonomous multifunctional epidermal touch panel. This touch panel offers impeccable input capabilities through word inscription and participation in the Chinese game of Go. Consequently, the TSA‐ionogel's innovation holds the potential to reshape the trajectory of next‐generation electronics and profoundly revolutionize the paradigm of human–machine interaction.
Electron‐Induced Degradation in Blue Quantum‐Dot Light‐Emitting Diodes

Published: December 2023

AbstractThe poor stability of blue quantum‐dot (QD) light‐emitting diodes (B‐QLEDs) hinders their application in displays. To improve the stability of B‐QLEDs, the degradation mechanism should be revealed. Here, the degradation mechanism of B‐QLEDs is investigated by monitoring the changes occurring in the QDs and the hole transport layers (HTL) during device operation, respectively. It is revealed that the accumulation of electrons within the QDs is responsible for the degradation of the devices. On the one hand, the accumulated electrons induce the detachment of oleic acid ligands, leading to permanent damage to the stability of B‐QDs. On the other hand, the accumulated electrons leak into the HTL or recombine at the HTL/QDs interface, leading to the degradation of HTL. The formation of surface defects in B‐QDs and the decomposition of HTL contribute to the degradation of B‐QLEDs. The results reveal the strong dependence of B‐QLEDs stability on the accumulated electrons, the QDs and the HTL, which can help researchers to develop effective design strategies for improving the lifespan of B‐QLEDs.

AbstractNanodiamonds (ND) hold great potential for diverse applications due to their biocompatibility, non‐toxicity, and versatile functionalization. Direct visualization of ND by means of non‐invasive imaging techniques will open new venues for labeling and tracking, offering unprecedented and unambiguous detection of labeled cells or nanodiamond‐based drug carrier systems. The structural defects in diamonds, such as vacancies, can have paramagnetic properties and potentially act as contrast agents in magnetic resonance imaging (MRI). The smallest nanoscale diamond particles, detonation ND, are reported to effectively reduce longitudinal relaxation time T1 and provide signal enhancement in MRI. Using in vivo, chicken embryos, direct visualization of ND is demonstrated as a bright signal with high contrast to noise ratio. At 24 h following intravascular application marked signal enhancement is noticed in the liver and the kidneys, suggesting uptake by the phagocytic cells of the reticuloendothelial system (RES), and in vivo labeling of these cells. This is confirmed by visualization of nanodiamond‐labeled macrophages as positive (bright) signal, in vitro. Macrophage cell labeling is not associated with significant increase in pro‐inflammatory cytokines or marked cytotoxicity. These results indicate nanodiamond as a novel gadolinium‐free contrast‐enhancing agent with potential for cell labeling and tracking and over periods of time.

AbstractCattle and the draught force provided by its skeletal muscle have been integral to agro‐ecosystems of agricultural civilization for millennia. However, relatively little is known about the cattle muscle functional genomics (including protein coding genes, non‐coding RNA, etc.). Circular RNAs (circRNAs), as a new class of non‐coding RNAs, can be effectively translated into detectable peptides, which enlightened us on the importance of circRNAs in cattle muscle physiology function. Here, RNA‐seq, Ribosome profiling (Ribo‐seq), and peptidome data are integrated from cattle skeletal muscle, and detected five encoded peptides from circRNAs. It is further identified and functionally characterize a 907‐amino acids muscle‐specific peptide that is named circNEB‐peptide because derived by the splicing of Nebulin (NEB) gene. This peptide localizes to the nucleus and cytoplasm and directly interacts with SKP1 and TPM1, key factors regulating physiological activities of myoblasts, via ubiquitination and myoblast fusion, respectively. The circNEB‐peptide is found to promote myoblasts proliferation and differentiation in vitro, and induce muscle regeneration in vivo. These findings suggest circNEB‐peptide is an important regulator of skeletal muscle regeneration and underscore the possibility that more encoding polypeptides derived by RNAs currently annotated as non‐coding exist.
