Published: May 2023

<p>Federated learning (FL) has gained increasing attention due to its ability to collaboratively train while protecting client data privacy. However, vanilla FL cannot adapt to client heterogeneity, leading to a degradation in training efficiency due to stragglers, and is still vulnerable to privacy leakage. To address these issues, this paper proposes RingSFL, a novel distributed learning scheme that integrates FL with a model split mechanism to adapt to client heterogeneity while maintaining data privacy. In RingSFL, all clients form a ring topology. For each client, instead of training the model locally, the model is split and trained among all clients along the ring through a pre-defined direction. By properly setting the propagation lengths of heterogeneous clients, the straggler effect is mitigated, and the training efficiency of the system is significantly enhanced. Additionally, since the local models is blended, it is less likely for an eavesdropper to obtain the complete model and recover the raw data, thus improving data privacy. The experimental results on both simulation and prototype systems show that RingSFL can achieve better convergence performance than benchmark methods on independently identically distributed (IID) and non-IID datasets, while effectively preventing eavesdroppers from recovering training data. <br>

Influence of the Lower Atmosphere on Wave Heating and Evaporation in Solar Coronal Loops
Authors: Guo Mingzhe , Duckenfield Timothy , Van Doorsselaere Tom , Karampelas Konstantinos , Pelouze Gabriel , Gao Yuhang 
Published: May 2023

Abstract
We model a coronal loop as a 3D magnetic cylinder in a realistic solar atmosphere that extends from the chromosphere to the corona. Kink oscillations, believed to be ubiquitous in the solar corona, are launched in the loop. Heating is expected owing to the dissipation of wave energy at small structures that develop from the Kelvin–Helmholtz instability induced by kink oscillations. Increases in temperature and internal energy can be observed in the coronal counterpart of the driven loop. With the presence of thermal conduction, chromospheric evaporation can also be seen. Although the volume-averaged temperature and density changes seem slight (∼4% relative to a nondriven loop), the enthalpy flow from the lower atmosphere redistributes the density and temperature in the vertical direction, thus enhancing the dissipation of wave energy in the corona. The efficient heating in the coronal counterpart of the loop can complement the thermal conductive losses shown in the current model and thus maintain the internal energy in the corona.
Quel est le potentiel thermal de la Corse et quelles sont les propositions faites pour le développer ?
Authors: Giacomini Thierry 
Published: May 2023

Sur les 12 sources d’eau minérale naturelle identifiées comme potentiellement exploitables pour le thermalisme en Corse, cinq pourraient accueillir des cures thermales contre une seule actuellement. La région ne manque pas d’atouts pour développer la filière thermale : une population locale adaptée, un flux touristique important, un environnement naturel exceptionnel. Cependant la difficulté d’accès aux stations thermales, le manque d’hébergement et de restauration de proximité, peuvent être dissuasifs pour les curistes. Il existe une volonté politique pour développer le moteur économique de la filière thermale en accompagnant les projets. Il sera nécessaire de mettre en place un mode de gestion efficace des établissements thermaux, de rénover et de développer les structures existantes. Pour développer le thermalisme en Corse, il faut adapter les cures thermales à la saisonnalité touristique, diversifier l’offre thermale avec le thermoludisme et les activités complémentaires de bien-être. Il faut fédérer tous les acteurs de la filière thermale : le corps médical de la région, les universitaires pour la réalisation des études cliniques, les spécialistes du bien-être et des activités physiques et les professionnels du tourisme.
Tu commentes donc je suis : stratégies de captation du public adolescent par les plateformes de lecture. Le cas de Webtoon
Authors: Rio Florence , Tadier Elsa 
Published: May 2023

À travers l’analyse des stratégies de Webtoon, plateforme de lecture coréenne visant à capter prioritairement le public adolescent, à la croisée de pratiques de production et d’appropriation, cet article vise à questionner un processus particulier au cœur de l’industrialisation de la lecture par le numérique, à savoir l’intensification d’une dynamique relationnelle comme un moteur de l’économie des plateformes culturelles. Cette économie relationnelle du lire, particulièrement porteuse auprès du public adolescent qui développe son autonomie et ses pratiques de sociabilité, se donne à voir sur Webtoon par le statut singulier accordé aux commentaires. Elle prend sens au sein d’une logique plus générale visant à s’adresser aux jeunes en s’appuyant notamment sur leur support privilégié : le smartphone. Ce faisant, les plateformes de lecture nous donnent à saisir une certaine représentation du public des lecteurs adolescents que questionne cet article, en analysant à la fois leurs modes d’adhésion et de contournements du fonctionnement de ces industries culturelles.

Authors: Movahedi Minoo , Farahbod Farinaz , Zarean Elahe , Hajihashemi Maryam , Haghollahi Fedyeh , Farahmand Mehri 
Published: May 2023

Background:
Chorionic villus sampling (CVS) is one of the invasive diagnostic methods used to diagnose chromosomal, genetic, and metabolic diseases in the embryonic period. The use of this method is associated with maternal and fetal consequences, the most serious of which is abortion. Therefore, the present study was conducted to investigate the incidence of these consequences and the factors affecting the incidence of abortion.

Materials and Methods:
A cross-sectional study was performed on 98 pregnant women with CVS indications. Maternal and fetal outcomes including abortion, vaginal bleeding, subchorionic hematoma, premature rupture of membrane (PROM), chorioamnionitis, preterm delivery, limb abnormality, fetal growth retardation, and preeclampsia were recorded.

Results:
The results of the present study showed that the incidence of fetal outcomes including fetal growth failure, premature rupture of membranes, abortion, and limb abnormalities was 4.1%, 7.1%, 3.1%, and 1%, and the incidence of maternal outcomes including preterm delivery, subchorionic hematoma, preeclampsia, and hemorrhage was 14.3%, 3.1%, 6.1%, and 10.2%, respectively. In addition, a decrease in free BHCG and an increase in NT were significantly associated with the occurrence of abortion (OR: 0.11 and 4.25, respectively, P value < 0.05).

Conclusion:
It should be noted that due to a long time between placental sampling and the occurrence of vaginal bleeding, premature rupture of membrane, and preterm delivery, it seems that placental sampling has no effect. In addition, only a decrease in free BHCG or an increase in NT significantly increased the chance of miscarriage.

Bacterial contamination of yoghurt cannot be overemphasized due to it physicochemical and sensory properties that might encouraged the growth of pathogenic bacteria. This study was done to determine the sensory property, physicochemical and Bacteriological examination of yoghurt made at home for home consumption and the one made and sold in Port Harcourt metropolis by the use of general microbiological techniques. Results gotten showed that sample B (Sweetened Home-made) had the best sensory properties when assessed as 47.6%; 52.5%;47.5%;27.5%;50% 32.5% for overall acceptability, most preferred, appearance/colour, aroma, flavor and texture/viscosity respectively. Proximate composition, mineral and vitamin content revealed that sample F had the best moisture content (87.33%); sample A had the highest ash content (1.73%); sample B had the highest crude protein and carbohydrate content (6.02%; 21.36); Sample C had the highest fat content (2.27%). The result of the iron (Fe) content of the different yoghurt samples revealed that sample C had more iron content (0.777mg/100g). The sodium content was high in sample A (44.875 mg/100g) and least in sample F (1.15 mg/100g). Sample B (216.963 mg/100g) had the highest calcium content while sample B (0.0047 U.I/100g) had the highest vitamin C content as compared to vitamin A content having the highest amount in sample A (0.097 mg/100g). The total heterotrophic bacterial counts ranged from 2.20±0.63x104 to 4.65±2.19x104CFU/ml for sample E and A respectively. The Total lactobacillus count ranged from 2.34±1.94x102 to 12.28±8.76x102CFU/ml for sample A and F respectively. There was no significant difference (p≥0.05) in the total heterotrophic bacterial and lactobacillus counts between the different milk samples analyzed. Forty-four (44) bacterial isolates were identified in this study belonging to the following genera; Bacillus spp, Staphylococcus spp. and Lactobacillus spp. Bacillus had the highest occurrence in sample B, C, D and F (11.36%) with least occurrence in sample A and F (6.36%). Staphylococcus had the highest occurrence in sample C (9.09) with least occurrence in sample E (2.27%). Lactobacillus has the highest abundance in sample D (6.82%). This study has revealed high bacterial load, proximate, mineral and vitamin content which might allow bacteria to thrive. There is need to advocate for proper storage of the yogurt to prevent bacterial contamination.

Tears, Fire, and Blood
Authors: Meriwether James H. 
Published: May 2023

In the mid-twentieth century, the struggle against colonial rule fundamentally reshaped the world and the lives of the majority of the world's population. Decolonization, Black and Brown freedom movements, the establishment of the United Nations and NATO, an exploding Cold War, a burgeoning world human rights movement, all became part of the dramatic events that swept through Africa at a furious pace, with fifty nations gaining independence in roughly fifty years. Meanwhile, the United States emerged as the most powerful and influential nation in the world, with the ability—politically, economically, militarily—and principles to help or hinder the transformation of the African continent.Tears, Fire, and Blood offers a sweeping history of how the United States responded to decolonization in Africa. James H. Meriwether explores how Washington, grappling with national security interests and racial prejudices, veered between strengthening African nationalist movements seeking majority rule and independence and bolstering anticommunist European allies seeking to maintain white rule. Events in Africa helped propel the Black freedom struggle around the world and ultimately forced the United States to confront its support for national ideals abroad as it fought over how to achieve equality at home.
Choctaw Confederates
Authors: Yarbrough Fay A. 
Published: May 2023

When the Choctaw Nation was forcibly resettled in Indian Territory in present-day Oklahoma in the 1830s, it was joined by enslaved Black people—the tribe had owned enslaved Blacks since the 1720s. By the eve of the Civil War, 14 percent of the Choctaw Nation consisted of enslaved Blacks. Avid supporters of the Confederate States of America, the Nation passed a measure requiring all whites living in its territory to swear allegiance to the Confederacy and deemed any criticism of it or its army treasonous and punishable by death. Choctaws also raised an infantry force and a cavalry to fight alongside Confederate forces.
In Choctaw Confederates, Fay A. Yarbrough reveals that, while sovereignty and states’ rights mattered to Choctaw leaders, the survival of slavery also determined the Nation’s support of the Confederacy. Mining service records for approximately 3,000 members of the First Choctaw and Chickasaw Mounted Rifles, Yarbrough examines the experiences of Choctaw soldiers and notes that although their enthusiasm waned as the war persisted, military service allowed them to embrace traditional masculine roles that were disappearing in a changing political and economic landscape. By drawing parallels between the Choctaw Nation and the Confederate states, Yarbrough looks beyond the traditional binary of the Union and Confederacy and reconsiders the historical relationship between Native populations and slavery.
Dismal Freedom
Authors: Morris J. Brent 
Published: May 2023

The massive and foreboding Great Dismal Swamp sprawls over 2,000 square miles and spills over parts of Virginia and North Carolina. From the early seventeenth century, the nearly impassable Dismal frustrated settlement. However, what may have been an impediment to the expansion of slave society became an essential sanctuary for many of those who sought to escape it. In the depths of the Dismal, thousands of maroons—people who had emancipated themselves from enslavement and settled beyond the reach of enslavers—established new lives of freedom in a landscape deemed worthless and inaccessible by whites. Dismal Freedom unearths the stories of these maroons, their lives, and their struggles for liberation. Drawing from newly discovered primary sources and archeological evidence that suggests far more extensive maroon settlement than historians have previously imagined, award-winning author J. Brent Morris uncovers one of the most exciting yet neglected stories of American history. This is the story of resilient, proud, and determined people who made the Great Dismal Swamp their free home and sanctuary and who played an outsized role in undermining slavery through the Civil War.
