Background: Understanding young women and men's perceived barriers and facilitators to participation in biomedical HIV prevention research is important for designing youth friendly services (YFS) and acceptable technologies, which are necessary for preventing high sustained HIV incidence in South Africa. This study explores the multileveled barriers and facilitators to young men and women's willingness to participate in hypothetical biomedical HIV prevention research.Methods: Eight age- (16–18 and 19–24 years) and gender-stratified focus group discussions (FGDs) were conducted using semi-structured interview guides to explore young South African women and men's willingness, perceived barriers, and facilitators to participating in biomedical HIV prevention research. FGD transcripts were uploaded to NVivo and coded collaboratively with youth study team members. Thematic analysis using Bronfenbrenner's ecological model (individual, inter-personal, community, and societal) was used to guide a deductive coding procedure, which was documented and compared by gender.Results: Thirty-one participants from Durban and 34 from Soweto participated in FGDs. Individual facilitators for participation were discussed more by young men and included financial incentives and altruism. Concerns about side-effects of biomedical products were a common barrier. Interpersonal relationships with peers, intimate partners and caregivers influenced young people's willingness to participate in HIV prevention research, more so among young women. For young women, gendered power dynamics and distrust of intimate partners and parents influenced both communication regarding participation and willingness to participate in research that is often stigmatized, due to societal norms around women's sexuality. On a societal level, participants expressed distrust in medical and research institutions, however a sense of community that was developed with the study staff of this project, was a motivator to participate in future studies.Discussion: At each level of the ecological model, we found participants expressed gendered barriers and facilitators for participation. Gender norms as well as distrust of partners, parents, and health care professionals were key barriers that cut across all levels. At each level participants discussed facilitators that were youth-engaged, underscoring the need to implement YFS, establish trust and address gender inequities within future biomedical HIV prevention studies wishing to engage and retain South African youth.
Self-Harm Among School-Going Adolescent Survivors of Sexual Violence Victimisation: A Cross-Sectional Study
Authors: Quarshie Emmanuel Nii-Boye 
Published: May 2021

Background: A growing body of evidence from high-income contexts suggests a strong association between sexual violence victimisation and self-harm and eventual suicide. However, both sexual violence and self-harm among adolescents are still less researched in sub-Saharan African countries, including Ghana.Objectives: To estimate the 12-month prevalence of self-harm, and to describe the associated factors and reported reasons for self-harm among school-going adolescent survivors of sexual violence victimisation during the previous 12 months in urban Ghana.Methods: Analytic data came from a regional-based representative cross-sectional survey including in-school youth (N = 1,723) conducted in 2017 within the Greater Accra Region of Ghana. Of these, 297 (17.2%) self-reported sexual violence victimisation in the previous 12 months; this proportion of the participants (n = 297) was the focus of the current study. Items measuring sexual violence victimisation, self-harm, and correlates were adopted from the 2012 Ghana WHO–Global School-based Student Health Survey and the Child and Adolescent Self-harm in Europe Study. Data analysis involved multivariable logistic regression models.Results: The estimate of self-harm ideation during the previous 12 months was 45.8% (95% CI: 40–52), whereas the estimate of self-harm behaviour was 38.7% (95% CI: 33–44). About two in five of the participants who reported self-harm wanted to die by their last episode of the behaviour. While bullying victimisation was associated with increased odds of self-harm ideation (aOR = 1.97, 95% CI 1.17, 3.31, p = 0.010) and behaviour (aOR = 2.76, 95% CI 1.59, 4.80, p &lt; 0.001), weekly alcohol use (aOR = 2.56, 95% CI 1.32, 4.93, p = 0.005), conflict with parents (aOR = 2.30, 95% CI 1.28, 4.12, p = 0.005), and physical abuse victimisation (aOR = 1.80, 95% CI 1.03, 3.15, p = 0.037) showed strong associations with increased odds of self-harm behaviour in the past 12 months.Conclusions: The evidence underscores the need for both universal and targeted multi-level intervention and prevention programmes to mitigate the offence of sexual violence and reduce the chances of self-harm among adolescent survivors of sexual violence in urban Ghana.
Geoeffectiveness Prediction of CMEs
Authors: Besliu-Ionescu Diana , Mierla Marilena 
Published: May 2021

Coronal mass ejections (CMEs), the most important pieces of the puzzle that drive space weather, are continuously studied for their geomagnetic impact. We present here an update of a logistic regression method model, that attempts to forecast if a CME will arrive at the Earth and it will be associated with a geomagnetic storm defined by a minimum Dst value smaller than −30 nT. The model is run for a selection of CMEs listed in the LASCO catalogue during the solar cycle 24. It is trained on three fourths of these events and validated for the remaining one fourth. Based on five CME properties (the speed at 20 solar radii, the angular width, the acceleration, the measured position angle and the source position – binary variable) the model successfully predicted 98% of the events from the training set, and 98% of the events from the validation one.

Published: May 2021

En los Valles Interandinos del Ecuador entre 2000 y 3000 m.s.n.m se tienen bajos rendimientos de quinua con alto riesgo por la variabilidad del clima y la siembra de variedades criollas con inadecuadas prácticas de manejo. La investigación determinó las cantidades de nutrientes extraídos por tres variedades de quinua (Chenopodium quinoa Willd), durante el desarrollo del cultivo. El objetivo fue determinar las cantidades de nitrógeno, fósforo, potasio, calcio y magnesio que la planta de quinua extrae durante su ciclo de vida. Se evaluaron tres variedades de quinua, se determinó la cantidad de materia seca, porcentaje de nutrientes en estudio y cantidad de nutriente en kg ha-1 de las muestras tomadas en hojas, tallos y panículas a los 20, 40, 60, 80, 100 y 120 días después de la siembra. Los resultados obtenidos indican que la variedad Imbaya con la dosis 150-80-40 de N, P, K mostro una mayor cantidad de materia seca acumulada en la planta total con 9870 kg ha-1 a los 120 días después de la siembra (dds). Los nutrientes más absorbidos por la planta de quinua fueron K y N seguido de Ca, Mg y P en este orden. Los índices de cosecha (IC) obtenidos fueron: N=0,63; P=0,64; K= 0,55; Ca=0,52 y Mg=0,65. La aplicación del fertilizante en el cultivo de quinua se debe realizar en tres épocas: en la siembra, a la deshierba a los 30 días y al aporque a los 50 días de edad del cultivo.

Abstract

Key Points

We evaluated risk factors for AKI requiring dialysis (AKI-D) in a cohort of 3186 patients hospitalized with coronavirus disease 2019.Patients who were Latino, men, and those with lower eGFR or obesity experienced more AKI-D. Patients with AKI-D had increased odds of mortality.After adjustment for covariates including baseline kidney function, proteinuria and hematuria were associated with increased odds of AKI-D.

Background
AKI is common in patients hospitalized with coronavirus disease 2019 (COVID-19). Risk factors for AKI requiring dialysis (AKI-D) are not fully understood. We aimed to identify risk factors associated with AKI-D and AKI not requiring dialysis (AKI-ND).

Methods
We reviewed electronic health records of 3186 patients aged ≥18 years old who were hospitalized with COVID-19 across six hospitals. Patient characteristics, urinalysis findings, and inflammatory markers were analyzed for association with in-hospital AKI status (AKI-D, AKI-ND, or no AKI), and we subsequently evaluated mortality.

Results
After adjustment for multiple covariates, higher baseline eGFR was associated with 30% lower odds of AKI-D and 11% lower odds of AKI-ND (for AKI-D, OR, 0.70; 95% CI, 0.64 to 0.77; for AKI-ND, OR, 0.89; 95% CI, 0.85 to 0.92). Patients with obesity and those who were Latino had increased odds of AKI-D, whereas patients with congestive heart failure or diabetes with complications had increased odds of AKI-ND. Females had lower odds of in-hospital AKI (for AKI-D, OR, 0.28; 95% CI, 0.17 to 0.46; for AKI-ND, OR, 0.83; 95% CI, 0.70 to 0.99). After adjustment for covariates and baseline eGFR, 1–4+ protein on initial urinalysis was associated with a nine-fold increase in odds of AKI-D (OR, 9.00; 95% CI, 2.16 to 37.38) and more than two-fold higher odds of AKI-ND (OR, 2.28; 95% CI, 1.66 to 3.13). Findings of 1–3+ blood and trace glucose on initial urinalysis were also associated with increased odds of both AKI-D and AKI-ND. AKI-D and AKI-ND were associated with in-hospital death (for AKI-D, OR, 2.64; 95% CI, 1.13 to 6.17; for AKI-ND, OR, 2.44; 95% CI, 1.77 to 3.35).

Conclusions
Active urine sediments, even after adjustment for baseline kidney function, and reduced baseline eGFR are significantly associated with increased odds of AKI-D and AKI-ND. In-hospital AKI was associated with in-hospital death. These findings may help prognosticate patients hospitalized with COVID-19.

Abdelkébir Khatibi and the Transparency of Language
Authors: Belhabib Assia 
Published: May 2021

A key topic in Abdelkébir Khatibi’s works is undeniably the way in which different parts of the social body do interact, intersect, ignore or even reject each other. A forerunner of postcolonial thought in Morocco, Khatibi explores this challenging question in his essays, more specifically Maghreb pluriel, Du bilinguisme, Chemins de traverse, but also in his dialogues with Jacques Derrida, Roland Barthes, Jacques Hassoun and Rita El Khayat. Khatibi’s vision cleverly scrutinizes human relationships, as well as links between societies that cannot be conceived of independently from group relationships. Playing skillfully with words, Khatibi highlights the importance of language in the formation of social barriers. A vigilant and insightful intellectual, Khatibi questions in his rich and complex work the language of Francophone writers since independence.
Silicon and Oxygen Isotope Evolution of the Inner Solar System
Authors: Tanaka Ryoji , Potiszil Christian , Nakamura Eizo 
Published: May 2021

Abstract
Enstatite chondrites have been regarded as major building blocks of the Earth and other differentiated inner planetary bodies due to the similarity of Δ17O (deviation of the δ
17O value from the terrestrial silicate fractionation line) and nucleosynthetic isotope anomalies. However, this hypothesis has been rebutted by the fact that the Earth and enstatite chondrites show distinct Si isotopic compositions. It has been debated whether the origin of this Si isotope difference is the result of nebular or planetary processes. Here we show that the δ
30Si (deviation of 30Si/28Si relative to NBS 28 standard) and the Δ17O values of chondrules in unequilibrated enstatite chondrites are between −0.20‰ and −0.54‰ and −0.36‰ and +0.26‰, respectively. Furthermore, the chondrules with higher Δ17O values tend to have lower δ
30Si. The data exhibit values consistent with most of the noncarbonaceous group differentiated planetary bodies. This consistency suggests that the Si and O isotopic compositions of enstatite chondrules record those of the major precursors that formed the differentiated planetary bodies in the inner solar system. Model calculations based on the results reveal that the Si and O isotope variations of the enstatite chondrite chondrules were generated by an interaction between the evaporation-driven SiO-rich gas and partially or fully melted forsterite-rich precursor chondrules. The Mg/Si of the evaporated dust-gas mixtures increased with increasing silicate/metal ratio in the evaporated dust, which may have increased the bulk Mg/Si and δ
30Si value of the inner planetary bodies.
A database and checklist of geometrid moths (Lepidoptera) from Colombia

Published: May 2021

Molecular DNA sequence data allow unprecedented advances in biodiversity assessments, monitoring schemes, and taxonomic works, particularly in poorly explored areas. They allow, for instance, the sorting of material rapidly into operational taxonomic units (such as BINs - Barcode Index Numbers), sequences can be subject to diverse analyses, and with linked metadata and physical vouchers they can be examined further by experts. However, a prerequisite for their exploitation is the construction of reference libraries of DNA sequences that represent the existing biodiversity. To achieve these goals for Geometridae (Lepidoptera) moths in Colombia, expeditions were carried out to 26 localities in the northern part of the country in 2015–2019. The aim was to collect specimens and sequence their DNA barcodes, and to record a fraction of the species richness and occurrences in one of the most biodiversity-rich countries. These data are the beginnings of an identification guide to Colombian geometrid moths, whose identities are currently often provisional only, being morpho species or operational taxonomic units (OTUs). Prior to the current dataset, 99 Geometridae sequences forming 44 BINs from Colombia were publicly available on the Barcode of Life Data System (BOLD), covering 20 species only.
We enrich the Colombian Geometridae database significantly by including DNA barcodes, two nuclear markers, photos of vouchers, and georeferenced occurrences of 281 specimens of geometrid moths from different localities. These specimens are classified into 80 genera. Analytical tools on BOLD clustered 157 of the mentioned sequences to existing species level BINs, identified earlier by experts. Another 115 were assigned to BINs that were identified to genus or tribe level only. 11 specimens did not match any existing BIN on BOLD, and are therefore new additions to the database. It is likely that many BINs represent undescribed species. Nine short sequences (<500bp) were not assigned to BINs but identified to the lowest taxonomic category by expert taxonomists and with comparisons of type material photos. The released new genetic information will help to further progress the systematics of Geometridae. An illustrated catalogue of all new records allows validation of our identifications; it is also the first document of this kind for Colombian Geometridae. All specimens are deposited at the Museo de Zoología of Universidad de Sucre (MZUS), North Colombia. DNA BINs are reported in this study, the species occurrences are available on SIB Colombia https://sibcolombia.net/ and the Global Biodiversity Information Facility (GBIF) https://www.gbif.org/ through https://doi.org/10.15472/ucfmkh.
César et l’apparat royal
Authors: Maillard Dimitri 
Published: May 2021

Quand le 15 février 44, à l’occasion des Lupercales, César se présente vêtu de la toge pourpre et s’assoit sur une chaise curule dorée, le dictateur réactive une tradition selon laquelle ces deux éléments n’étaient associés que pour les anciens rois. Un point vient appuyer cette hypothèse : toge pourpre et chaise curule font partie des insignes de pouvoir offerts par le Sénat aux souverains alliés. Le propos s’attache à démontrer la nature royale de ces dons, qui pourraient se fonder sur un costume antérieur à l’apparat républicain. L’incompatibilité entre la chaise curule et la pourpre est levée par César aux Lupercales ; l’ensemble n’est pas commenté par ses contemporains, du fait du diadème tendu par Antoine ce jour-là, mais César réactivait en fait l’ancien apparat royal.

Published: May 2021

Heart rate is one of the most important vital signs. People usually face high tension in routine life, and if we found an effective method to control the heart rate, it would be very desirable. One of the goals of this paper is to examine changes in heart rate before and during meditation. Another goal is that what impact could have meditation on the human heartbeat.To heart rate analysis before and during meditation, available heart rate signals have been used for the Physionet database that contains 10 normal subjects and 8 subjects that meditation practice has been done on them. In this paper, first is paid to extract linear and nonlinear characteristics of heart rate and then is paid to the best combination of features to identify two intervals before and during meditation using MLP and SVM classifiers with the help of sensitivity, specificity and accuracy measurements.The achieved results in this paper showed that choosing the best combination of a feature to make a meaningful difference between two intervals before and during meditation includes two-time features (Mean HR, SDNN), a frequency feature ( ), and three nonlinear characteristics ( ). Also, using the support vector machine had better results than the MLP neural network. The sensitivity, specificity, and accuracy of the mean and standard deviation obtained respectively like 92.73 0.23, 89.05 0.67, 89.97 0.23 by using MLP and respectively like 95.96 0.09, 93.80 0.16, and 94.90 0.14 by using SVM.As a result, using meditation can reduce the stress and anxiety of patients by effects on heart rate, and the treatment process speeds up and have an important role in improving the performance of the system.

Published: May 2021

Background:
Our study aimed to evaluate right ventricular (RV) morphology and strain (S) in the early stage of familial transthyretin (TTR) cardiac amyloidosis (CA).

Methods and Results:
Thirty-seven patients with transthyretin mutation underwent 99mTc-3,3-diphosphono-1,2 propanodicarboxylic acid (99mTc-DPD) scans and/or cardiac magnetic resonance (CMR) to identify TTR CA. Each patient underwent echocardiography to quantify RV dimensions, tricuspid annular plane systolic excursion (TAPSE), systolic pulmonary artery pressure (sPAP), longitudinal (L) strain of the RV free wall, left ventricular (LV) septal thickness (ST), ejection fraction, E/E', LV global (G) L, radial (R), and circumferential (C) S. 99mTc-DPD and CMR revealed the accumulation in 22 of 37 patients (CA group) and no accumulation in 15 patients (no-CA group). Left ventricular (LV) septal thickness (ST) was higher (P < 0.0001) while LV ejection fraction and E/E' were lower (P < 0.05) in the CA group than the no-CA group. LV-global longitudinal strain (LS) was lower (P < 0.0001) in the CA-group than the no CA-group, whereas LV-global circumferential strain and LV-global radial strain were similar. The CA group showed higher values of RV dimensions (P < 0.05) and sPAP (0.02) and a lower (P = 0.002) TAPSE. Globally, RV-LS was lower (P = 0.005) in the CA group than the no-CA group. Basal and mid segments of the RV free wall showed a lower LS in the CA group than the no-CA group (P < 0.01), while apical S was similar between groups.

Conclusions:
RV deformation, particularly in basal and mid segments, is early impaired in CA.
