Experimental evidences of defect luminescence spanning red to near-infrared in strongly quantum confined sub-4 nm CuInSe2 quantum dots approaching crystallization limit
Authors: Xu Huaixiu , Liang Tianyuan , Ma Wenjie , Ji Xuan , Miao Ruonan , Fan Jiyang 
Published: May 2021

Abstract
The CuInSe2 quantum dots (QDs) are “green” infrared optoelectronic materials with fruitful optically active point defects, but their roles in photodynamics remain unclear. We observe different types of stoichiometry-sensitive emission bands spanning red-near-infrared region in strongly quantum confined CuInSe2 QDs. The saturation of photoluminescence intensity versus excitation power follows law I ∝ P

k
with 0.54 < k <0.94 that is characteristic of defect dominated photon emission. The radiative quantum transitions have lifetimes of 15.2–32.0 μs that are far longer than usual interband transition lifetimes by three orders of magnitude. Multiple defects-involved electron transition processes are revealed.

Authors: Лиско Б. О. , Михайлишин В. П. 
Published: May 2021

Розроблено алгоритм опрацювання результатів досліджень постійної поправки електронних тахеометрів. Його суть полягає у використанні методу Гауса та знаходженні мінімуму деякої функції визначення похибок виміряних віддалей. Спочатку було досліджено кількість необхідних вимірювань для приладу: розглянуто вплив кореляційної залежності між величинами інструментальної і випадкової похибок. Далі складено систему рівнянь на підставі залежностей між довжиною виміряного створу та його відрізків у всіх комбінаціях з урахуванням постійної поправки віддалеміра. Отже, отримано умовні рівняння з однією невідомою – постійною поправкою віддалеміра. За наявністю великої кількості вимірювань розв'язання такої системи рівнянь полягає у знаходженні мінімуму деякої функції визначення похибок виміряних віддалей. При цьому найдоцільнішим вибором є критерій мінімізації максимального відхилення, який дає змогу відбракувати грубі помилки у виміряних значеннях. Отже, отримано найімовірніше значення постійної поправки віддалеміра, значення довжин виміряного створу та його відрізків, які будуть узгодженими у всіх можливих комбінаціях. Дослідження здійснено на геодезичному полігоні за оптимальних метеорологічних умов. З'ясовано, що запропоновані технологічні рішення можуть підвищити точність урівноваження значення постійної поправки віддалеміра, довжин виміряного створу та його відрізків, порівняно із відомим методом корелат, мінімум на 10 %. На прикладі дослідження тахеометра SOUTH NTS-350 встановлено, що точність отриманих апроксимованих значень довжин створу і його відрізків практично у три рази вища від задекларованої у технічних характеристиках СКП вимірювання довжин ліній цим самим приладом.
Analysis of Time–Distance Helioseismology for Detection of Emerging Active Regions
Authors: Stefan John T. , Kosovichev Alexander G. , Stejko Andrey M. 
Published: May 2021

Abstract
A time–distance helioseismic technique, similar to the one used by Ilonidis et al., is applied to two independent numerical models of subsurface sound-speed perturbations to determine the spatial resolution and accuracy of phase travel time shift measurements. The technique is also used to examine pre-emergence signatures of several active regions observed by the Michelson Doppler Imager and the Helioseismic Magnetic Imager. In the context of similar measurements of quiet-Sun regions, three of the five studied active regions show strong phase travel time shifts several hours prior to emergence. These results form the basis of a discussion of noise in the derived phase travel time maps and possible criteria to distinguish between true and false-positive detection of emerging flux.
A Focused Transport-based Kinetic Fractional Diffusion-advection Equation for Energetic Particle Trapping and Reconnection-related Acceleration by Small-scale Magnetic Flux Ropes in the Solar Wind
Authors: le Roux J. A. , Zank G. P. 
Published: May 2021

Abstract
Analysis of energetic particle inner heliospheric spacecraft data increasingly suggests the existence of anomalous diffusion phenomena that should be addressed to achieve a better understanding of energetic particle transport and acceleration in the expanding solar wind medium. Related to this is fast-growing observational evidence supporting the long-standing prediction from magnetohydrodynamic (MHD) theory and simulations of the presence of an inner heliospheric, dominant quasi-two-dimensional MHD turbulence component that contains coherent contracting and merging (reconnecting) small-scale magnetic flux rope (SMFR) structures. This suggests that energetic particle trapping in SMFRs should play a role in anomalous diffusion in the solar wind that warrants further investigation. However, progress in studying such anomalous energetic particle transport phenomena in the solar wind is hampered by the lack of a fundamental derivation of a general fractional kinetic transport equation linking macroscopic energetic particle fractional transport to the microscopic physics of energetic particle interaction with SMFR structures. Here, we outline details of how one can derive a closed ensemble-averaged focused transport equation in the form of a general kinetic fractional diffusion-advection equation from first principles following the nonlinear Eulerian correlation function closure approach of Sanchez et al. With this equation one can model the anomalous diffusion of energetic particles in ordinary, momentum, and pitch-angle space in response to particle trapping in numerous SMFRs advected with the solar wind flow.
L’exode dans l’Eure : accueillir, partir, revenir (printemps 1940-printemps 1941)
Authors: Catros Simon 
Published: May 2021

L’exode de 1940 a laissé dans la mémoire collective l’image d’un flot apeuré de familles et d’individus fuyant éperdument l’envahisseur, bref moment de folie collective et de dislocation sociale et étatique circonscrit au printemps 1940. L’étude de l’exode conduite à l’échelle du département de l’Eure offre une image beaucoup plus nuancée de l’exode : à l’échelle individuelle, on constate l’existence de stratégies en vue de réaliser un objectif, souvent atteint – rejoindre le foyer d’un proche ou d’un parent, par exemple. À l’échelle des structures sociales et administratives, le rôle des acteurs publics et associatifs paraît essentiel dans la gestion des flux de réfugiés, en particulier dans la prise en charge de certains réfugiés fragiles – patients hospitalisés, enfants. Enfin, il semble nécessaire de prendre en compte des temporalités plus large que le printemps 1940 pour comprendre les logiques de l’exode, qui apparaît finalement comme une expérience éminemment plurielle.
Initial Experiences in the Use of Portable Chest Radiography as a Tool to Guide Clinical Management of COVID-19 Positive Patients in Resource Limited Settings
Authors: Khandediya Ojaswi Bharat , Narasimhan Dindigal Ramakrishnan , Kapoor Priti , Sinha Sagar 
Published: May 2021

Introduction:
Radiological diagnosis of COVID-19 has shifted from the use of routine chest X-rays (CXRs) early on during the pandemic to high-resolution computed tomography (HRCT) of the chest to accurately describe the pattern of COVID involvement of the lungs. The morphological patterns seen at HRCT are increasingly being tapped into by a clinician in the management of this uncharted territory, for example, HRCT lung findings are categorized into three distinct phenotypes by an intensivist for guiding advanced ventilatory management of COVID patients. However, in resource-limited settings, HRCT places a heavy burden on the radiology departments and poses an enormous challenge to infection control in the CT suite. Our study aims to describe CXR patterns of COVID-19 acquired by portable radiography units and correlate them to symptom onset and progression in an attempt to enroll it as a reliable tool to assist clinical management including intensive unit care and ventilatory support.

Methodology:
Our study was a retrospective observational study of portable CXR findings in all patients diagnosed as COVID-19 positive by reverse transcription-polymerase chain reaction at a tertiary medical center from April to May 2020.

Results:
A total of fifty patients were included in the study, and the presence or absence of CXR findings in the presence or absence of clinical symptoms was analyzed. Our study showed that 24 (48%) patients had baseline features of lung involvement on CXR. Patients who presented with fever or breathlessness were found to be highly likely to show changes on the CXR. The most commonly noted changes were ground-glass opacities in 31 (63%) of patients with a bilateral, peripheral pattern of involvement seen in the lower zones of the lungs.

Conclusion:
While the higher sensitivity of the HRCT is of great clinical value, the portable CXR offers a feasible alternative to screen, follow clinical progress, and assist management of COVID-19 patients and should be considered as a means to reduce radiological service demands and reduce the risk of cross-infection.
Risk of Teenage Pregnancy Among Adolescents with Borderline Personality Disorder
Authors: Chen Mu-Hong , Tsai Shih-Jen 
Published: May 2021

Background:
Evidence suggested that borderline personality disorder (BPD) is related to the increased likelihood of risky sexual behaviors and that BPD is one of the most important risk factors of teenage pregnancy among adolescents. But whether adolescent BPD is independently associated with teenage pregnancy remains uncertain.

Methods:
We enrolled 809 adolescent girls with BPD and 8,090 without BPD between 2001 and 2009 and followed them up to the end of 2011 for the identifying any teenage pregnancy and repeated teenage pregnancy. Comorbidities of depressive disorder, bipolar disorder, as well as alcohol and substance use disorder were assessed. Psychotropic medications including antidepressants, mood stabilizers, and second-generation (atypical) antipsychotics were also identified.

Results:
Using Cox regression analyses with an adjustment of demographic characteristics, psychiatric comorbidities, and psychotropic medications showed that adolescents with BPD had significant increased risks of any teenage pregnancy (hazard ratio [HR] = 14.53, 95% confidence interval [CI] = 9.89–21.37, p < 0.05), and repeated teenage pregnancy (HR = 30.43, 95% CI = 17.32–53.45, p < 0.05) during the follow-up compared with non-BPD controls. Psychotropic medications were not significantly associated with the risks of any teenage pregnancy and repeated teenage pregnancy.

Discussion:
Adolescent BPD was an independent risk factor of any teenage pregnancy and repeated teenage pregnancy, regardless of the comorbidities of alcohol and substance use disorders. Whether the prompt intervention toward adolescent BPD may reduce the risks of any teenage pregnancy and repeated teenage pregnancy would need further investigation.
Interrelated and Multi-Dimensional Factors Affecting Quality Basic Education in Nandom Municipality of the Upper West Region of Ghana
Authors: Derkong-Dery Lazarus , Agbley Gideon Kofi 
Published: May 2021

Worldwide, quality education is a platform for social and personal development. In recent times, pupils in basic schools in Nandom Municipality seem not to acquire critical learning skills and consequently are underperforming. This paper investigates the interrelated and multi-dimensional factors affecting quality education in basic schools in the Nandom Municipality. Through the system andhuman capital theories, the paper draws a link between the various kinds of educational inputs pupils receive, the processing of such inputs and their outcomes, which reflect in their academic performance at the Basic Education Certificate Examination (BECE). The study employed a mixed research methods design. Cluster sampling technique and purposive sampling technique were used to selectrespondents. The study found that many pupils are not acquiring foundational knowledge in Literacy and Mathematics as reflected in the BECE performance due to inadequate educational resources, poor school management and supervision, and family socio-economic background factors. The study concludes that the quest for quality education for pupils would continue to be illusive unless thefundamentals underpinning quality education such as school resources and management are improved. It is recommended that government provides adequate educational resources for schools and reinforces the decentralisation concept of school management.

The Role of Dagbani Movies in Promoting Peaceful Co-existence in Northern Region, Ghana
Authors: Tuurosong Damasus 
Published: May 2021

This study explores themes in Dagbani movies which enhance peace-building, and discusses cultural conflict resolution techniques employed in Dagbani movies for peace-building. Qualitative research design was employed for the study. Focus group discussions and interviews were used for data collection. The study used Agenda Setting theory as analytical framework, and undertook thematic analysis to tease out messages in the content of selected movies. It showed that Dagbani movies contain lessons on peace-building and have become reference materials for opinion leaders and peace campaigners within Dagbon. Out of 11 movies sampled, six exposed bad traditional leadership with a view to admonishing Dagbon chiefs to desist from acts that could promote conflicts. Dagbani movies, re-establish working relations among warring factions, deal with systemic issues underlying conflicts and rebuild mutual relationships. The movies advocate the use of traditional peace-building techniques for conflict resolution. The study concludes that if movie producers get the support of relevant stakeholders, Dagbon movies could be effective in resolving conflicts. It recommends that film makers solicit funding from donor agencies and non-governmental organisations (NGOs) to produce movies targeted at maintaining peace in Dagbon.

DNA damage and necroptosis induced by peroxidase from proso millet in human colorectal cancer cells
Authors: Cui Xiaodong , Cao Zhongqi , Wang Zhuanhua 
Published: May 2021

Purpose: To investigate the effects of cationic peroxidase from proso millet (PmPOD) on DNA damage and necroptosis in human colon cancer HCT116 and HT29 cells.
Methods: Cell necroptosis and cell cycle was stained using Annexin V-FITC and cell cycle kits, respectively, and evaluated by flow cytometry. Lipid raft on the membrane was disrupted by cholesterol depletion and the location of PmPOD observed by confocal microscopy. Comet assays were used to detect DNA damage, and different inhibitors were also used. Knockdown of p53 or ectopic p53 expression in HCT116 cells were transfected p53 siRNA and pCMV3-TP53-myc plasmid, and p53 expression analyzed by western blotting.
Results: Pre-treatment of HCT116 and HT29 cell lines with the specific necroptosis inhibitor Nec-1 prevented PmPOD-induced necroptosis, whereas the apoptosis inhibitor, z-VAD-fmk, had no effect. The entry of PmPOD is necessary for induction of DNA damage and necroptosis. Furthermore, PmPOD induced cell cycle arrest at S phase, as well as DNA DSBs in vivo, as reflected by numerous γ-H2AX foci in CRC cells. However, the tumor suppressor protein, p53, alleviated PmPOD-induced DNA damage and necroptosis.
Conclusions: These results demonstrate that PmPOD-induced DNA DSBs in CRC cells is the main cause of necroptosis, and that the tumor suppressor protein, p53, alleviates PmPOD-induced necroptosis by promoting p53-mediated repair pathways.

The pseudodichotomous Dasya sylviae sp. nov. (Delesseriaceae, Ceramiales) from 60–90 m mesophotic reefs off Bermuda
Authors: Schneider Craig W. , Cassidy Margaret M. , Saunders Gary W. 
Published: May 2021

The red alga Dasya sylviae C.W.Schneid., M.M.Cassidy & G.W.Saunders sp. nov. is described from mesophotic depths of 60–90 m off Bermuda. Genetic sequences (COI-5P, rbcL) and morphological characteristics show that this species is distinct from other known pseudodichotomous species of Dasya. Of ten current species in the genus reported from Bermuda, only three, D. collinsiana M.Howe, D. cryptica C.W.Schneid., Quach & C.E.Lane and D. punicea (Zanardini) Menegh., share the overall pattern of pseudodichotomous branching in their axes; however, key morphological features easily distinguish them from D. sylviae sp. nov. The species most similar in habit to D. sylviae sp. nov. is D. crouaniana J.Agardh (type locality West Indies), but it bears shorter pseudolateral branches, and broader and longer tetrasporangial stichidia than the new species. Unique among the species of Dasya, D. sylviae sp. nov. lacks post-sporangial cover cells in tetrasporangial stichidia.

Published: May 2021

Les données sur le statut civil peuvent-elles ne pas être représentatives de la réalité conjugale des femmes filicides ? L’examen de la situation de cohabitation serait-il plus approprié de nos jours que les statuts généralement invoqués dans les écrits sur le sujet ? À partir d’un échantillon québécois constitué de 42 femmes filicides, plusieurs variables ont été comparées entre deux sous-groupes selon la présence ou non d’un conjoint cohabitant avec elles au moment du passage à l’acte. Quelques différences significatives ont été notées et nous ont permis une meilleure compréhension de certains aspects situationnels et dynamiques pour chacun des sous-groupes étudiés.
Repérage et évaluation de la littérature scientifique concernant le syndrome de la femme battue
Authors: Marleau Jacques D. , Beaudet Normand 
Published: May 2021

Au cours des dernières décennies, plusieurs syndromes ont vu le jour, autant dans la littérature biomédicale et sociale que dans la littérature pseudo-scientifique. En particulier, le syndrome de la femme battue est régulièrement soulevée lors d’expertise en Cour dans plusieurs pays depuis quelques années. L’objectif de cette recherche est de repérer et d’évaluer la qualité scientifique d’articles traitant du syndrome de la femme battue afin de simuler une démarche valable et réaliste de recherche documentaire réalisée par un témoin expert. Trois banques de données ont été consultées : PsychINFO (1984-2002), Medline (1966-2002), et National Criminal Justice Reference Service (NCJRS) (1972-2002).
