В настоящее время достигнут значимый прогресс в многослойных зеркалах нормального падения ВУФ диапазона спектра. В первую очередь, это касается повышения коэффициента отражения на рабочей длине волны, уменьшения спектральной ширины кривой отражения, появления высокоэффективных МС покрытий для коротковолнового (3-9 nm) и длинноволнового (более 50 nm) участков спектра. Создание таких зеркал открывает новые возможности для проведения астрофизических исследований Солнца, так как узкие спектральные ширины зеркал в сочетании с высоким коэффициентом отражения позволяют регистрировать изображения солнечной короны в монохроматических линиях. Особенно перспективным является использование телескопов на базе этих зеркал для динамической спектральной диагностики полного диска Солнца методом изображающей спектроскопии. Метод основан на регистрации монохроматических изображений Солнца в линиях ВУФ диапазона спектра с высоким пространственным и временным разрешением. Обсуждается возможный прогресс в солнечных исследованиях с применением этого типа оптики. Ключевые слова: солнечная корона, изображающая спектроскопия.

Local resistive switching in the contact of an atomic force microscope (AFM) probe to ZrO2(Y) films (including those with a Ta2O5 sublayer) on conducting substrates was studied. Switching was performed by triangular voltage pulses with the imposition of a high-frequency sinusoidal signal. The dependence of the difference in the current strength through the AFM probe in the low-and high-resistance States of dielectric films on the frequency of the high-frequency sinusoidal signal was observed at frequencies corresponding to the characteristic frequency of jumps of O2 ions - for oxygen vacancies in ZrO2 (Y) and Ta2O5 at 300K. The effect is associated with resonant activation of O2 ion migration along with oxygen vacancies by an external high-frequency electric field.

Published: July 2020

An expression for the free energy of forming an island from a catalyst droplet in the vapor-liquid-solid growth of III-V nanowires is obtained. The effect of the droplet depletion with its group V (As) content is studied in the presence of material influx from vapor. Different growth regimes of a nanowire monolayer are theoretically analyzed, including the regime with the stopping size under very low As concentrations in liquid. It is shown that the island stops growing when the As content in the droplet decreases to its equilibrium value. The obtained results should be useful for understanding and modeling the growth kinetics of III-V nanowires, their crystal phase, nucleation statistics and length distributions within the ensembles of nanowires as well as the doping process.

Authors: Holtz Bree E , McCarroll Alexis M , Mitchell Katharine M
Published: July 2020

Background

Many college students who have mental health issues do not receive professional care for various reasons. Students who do not receive help often have both short- and long-term adverse health outcomes. Mobile apps for mental health services such as MySSP, a service provided to college students through their university, may help eliminate barriers to seeking mental health care and result in more positive outcomes for college students.

Objective

This qualitative study aims to better understand college students’ perceptions and attitudes toward the adoption and use of a mobile phone app for mental health, MySSP, using the technology acceptance model (TAM).

Methods

A series of nine focus groups were conducted with college students (N=30) between February and May 2019 at a large, public Midwestern university. The moderator’s guide was based on the TAM, and focus group sessions primarily focused on the use and knowledge of apps for mental health, specifically, MySSP. The focus group transcriptions were hand-coded to develop a set of themes that encompassed students’ perceptions and attitudes toward MySSP.

Results

The analysis of the focus groups suggested the following themes: (1) existing awareness of the app, (2) perceived usefulness, (3) perceived ease of use, (4) attitudes toward apps for mental health and MySSP, and (5) social influence.

Conclusions

The results of this study provide deeper insights into the perceptions of a mobile app for mental health among college students. Future research should explore the specific contexts in which an app for mental health will be most effective for college students.
An Ovarian Reserve Assessment Model Based on Anti-Müllerian Hormone Levels, Follicle-Stimulating Hormone Levels, and Age: Retrospective Cohort Study
Authors: Xu Huiyu , Shi Li , Feng Guoshuang , Xiao Zhen , Chen Lixue , Li Rong , Qiao Jie
Published: July 2020

Background

Previously, we reported a model for assessing ovarian reserves using 4 predictors: anti-Müllerian hormone (AMH) level, antral follicle count (AFC), follicle-stimulating hormone (FSH) level, and female age. This model is referred as the AAFA (anti-Müllerian hormone level–antral follicle count–follicle-stimulating hormone level–age) model.

Objective

This study aims to explore the possibility of establishing a model for predicting ovarian reserves using only 3 factors: AMH level, FSH level, and age. The proposed model is referred to as the AFA (anti-Müllerian hormone level–follicle-stimulating hormone level–age) model.

Methods

Oocytes from ovarian cycles stimulated by gonadotropin-releasing hormone antagonist were collected retrospectively at our reproductive center. Poor ovarian response (<5 oocytes retrieved) was defined as an outcome variable. The AFA model was built using a multivariable logistic regression analysis on data from 2017; data from 2018 were used to validate the performance of AFA model. Measurements of the area under the curve (AUC), sensitivity, specificity, positive predictive value, and negative predicative value were used to evaluate the performance of the model. To rank the ovarian reserves of the whole population, we ranked the subgroups according to the predicted probability of poor ovarian response and further divided the 60 subgroups into 4 clusters, A-D, according to cut-off values consistent with the AAFA model.

Results

The AUCs of the AFA and AAFA models were similar for the same validation set, with values of 0.853 (95% CI 0.841-0.865) and 0.850 (95% CI 0.838-0.862), respectively. We further ranked the ovarian reserves according to their predicted probability of poor ovarian response, which was calculated using our AFA model. The actual incidences of poor ovarian response in groups from A-D in the AFA model were 0.037 (95% CI 0.029-0.046), 0.128 (95% CI 0.099-0.165), 0.294 (95% CI 0.250-0.341), and 0.624 (95% CI 0.577-0.669), respectively. The order of ovarian reserve from adequate to poor followed the order from A to D. The clinical pregnancy rate, live-birth rate, and specific differences in groups A-D were similar when predicted using the AFA and AAFA models.

Conclusions

This AFA model for assessing the true ovarian reserve was more convenient, cost-effective, and objective than our original AAFA model.

El principio de alternatividad como cláusula de cierre dentro del concurso de leyes
Authors: Carnevali Rodríguez Raúl , Salazar Zenteno Cristóbal
Published: July 2020

Tradicionalmente, la ciencia penal ha cuestionado la validez del principio de alternatividad, entendiendo que se encuentra comprendido dentro de otras reglas que informan el concurso aparente de leyes, principalmente, los principios de especialidad y consunción, es decir, carecería de autonomía. Sin embargo, a pesar de las interrogantes que la alternatividad presenta, su aplicación se justifica sobre la base de ciertos supuestos. Si bien se lo ha explicado sobre la base de “errores legislativos” —lo que no deja de ser cierto—, también puede hallarse su basamento en razones de proporcionalidad, entre otras. El trabajo analiza el desarrollo del principio en el derecho comparado y su recepción en la doctrina chilena. Aunque se concluye que su aplicación es más bien limitada sí ofrece respuestas satisfactorias, estimándose que un precepto como el artículo 8 del Código penal español tiene efectiva capacidad de rendimiento. Además de lo expuesto, se examina la diferencia que puede presentarse entre el concurso de leyes y el concurso aparente de leyes, que no solo sería una cuestión semántica, lo que permite una mayor operatividad al principio examinado, entendiéndolo como cláusula de cierre dentro del sistema concursal.

Published: July 2020

Objective: In the present research work, oral gastro retentive dosage forms (GRDFs) of capecitabine (CPC) were formulated using floating concept.

Methods: GRDFs were formulated using hydroxypropyl methyl cellulose (HPMC K4M and K15M) as drug release retardant, sodium bicarbonate (NaHCO3) and calcium carbonate (CaCO3) as gas generating agents, and micro crystalline cellulose (MCC), dicalcium phosphate (DCP), spray dried lactose (SDL), and pre gelatinized starch (PGS) as fillers. The tablets were prepared by direct compression method and evaluated for various parameters. The GRDFs were also characterized by Fourier-transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC).

Results and Discussion: All the formulations were subjected for pre and post compression parameters, shows all the data within the limits. The lag times of GRDFs has decreased significantly for formulations containing calcium carbonate when compared to sodium bicarbonate as gas generating agent. In vitro drug release studies indicate that higher polymer concentration delayed the CPC release, and the sustaining effect was in the order K4M > K15M > LVCR 100. Addition of MCC, DCP, SDL, and PGS as fillers further affected the lag time and in turn the CPC release rates.

Conclusion: The formulation (F9) containing 10%w/w HPMC K4M as the release retardant, microcrystalline cellulose as filler and 20%w/w CaCO3 as gas generating agent fulfilled regulatory requirements in terms of percent drug release at the end of 24h.

Este artigo apresenta um estudo de caso ligado à Universidade de São Paulo (USP), por meio de uma discussão que relaciona dados numéricos da Agência USP de Cooperação Acadêmica e Internacional (AUCANI), referentes ao número de alunos estrangeiros recebidos por essa universidade, às ações que ela executa no âmbito do ensino de Português como Língua Adicional. De modo geral, os dados permitem notar que a gestão universitária tem avançado, no sentido de estabelecer ações ligadas ao ensino de língua portuguesa como parte de seu processo de internacionalização IN, seja via AUCANI ou via Centro de Línguas. Por outro lado, também permitem considerar que as ações ainda não são suficientes em termos quantitativos e em relação a abarcar níveis de ensino mais avançados do português brasileiro. PALAVRAS-CHAVE: internacionalização IN; português como língua adicional; universidade de são paulo.
AS CONFISSÕES-DEPOIMENTO SOBRE O USO DA LÍNGUA ESTRANGEIRA INGLESA NO PROGRAMA DE MOBILIDADE INTERNACIONAL CIÊNCIA SEM FRONTEIRAS
Authors: Lingnau Carina Merkle , Navarro Pedro Luis
Published: July 2020

O Programa Ciência sem Fronteiras (CsF) foi uma ação política de mobilidade internacional para acadêmicos de graduação, pós-graduação entre outras modalidades. Nesse programa, era muito importante que o acadêmico/a soubesse uma língua estrangeira, em especial, a língua estrangeira inglesa.  Esse trabalho apresenta como objetivo analisar as confissões-depoimento dos acadêmicos egressos do Programa Ciência sem Fronteiras da UTFPR, câmpus Francisco Beltrão, bem como também analisar confissões-depoimento de servidores docentes e técnico-administrativos. Essas análises foram feitas em relação ao uso da língua estrangeira inglesa durante o ano de mobilidade no país acolhedor. Como metodologia utilizamos levantamento bibliográfico, pesquisa documental, entrevistas narrativas e o chamado método arquegenealógico, depreendido dos trabalhos do filósofo francês Michel Foucault. Os resultados mostraram que o uso da língua estrangeira inglesa no programa CsF se fez necessário durante o intercâmbio, embora nem sempre os acadêmicos tivessem fluência no idioma. Essa reflexão em torno do saber-poder, língua inglesa e CsF demonstrou a relação direta entre o poder, a criação do CsF e acadêmicos pouco preparados no idioma estrangeiro.PALAVRAS-CHAVE: inglês; discurso; programa de intercâmbio universitário; globalização.

O estudo está fundamentado em reflexões sobre leitura e compreensão textual, o conceito de tradução, o funcionamento da tradução através das máquinas, e o uso do tradutor automático como uma estratégia de compreensão leitora em inglês para propósitos acadêmicos. Os resultados apontam diferenças entre os tradutores escolhidos, indicando maior confiabilidade/eficiência de acordo com o sistema empregado, bem como evidenciam a importância da instrumentalização do ensino de estratégias de leitura para garantir a compreensão.PALAVRAS-CHAVES: tradutor automático; leitura; texto científico; inglês para propósitos acadêmicos
ON THE SIGNIFICANCE OF PRAISE
Authors: Stout Nathan
Published: July 2020

In recent years there has been an explosion of philosophical work on blame. Much of this work has focused on explicating the nature of blame or on examining the norms that govern it, and the primary motivation for theorizing about blame seems to derive from blame’s tight connection to responsibility. However, very little philosophical attention has been given to praise and its attendant practices. In this paper, I identify three possible explanations for this lack of attention. My goal is to show that each of these lines of thought is mistaken and to argue that praise is deserving of careful, independent analysis by philosophers interested in theorizing about responsibility.

OBJECTIVE

The FreeStyle Libre (FSL) flash glucose-monitoring device was made available on the U.K. National Health Service (NHS) drug tariff in 2017. This study aims to explore the U.K. real-world experience of FSL and the impact on glycemic control, hypoglycemia, diabetes-related distress, and hospital admissions.

RESEARCH DESIGN AND METHODS

Clinicians from 102 NHS hospitals in the U.K. submitted FSL user data, collected during routine clinical care, to a secure web-based tool held within the NHS N3 network. The t and Mann-Whitney U tests were used to compare the baseline and follow-up HbA1c and other baseline demographic characteristics. Linear regression analysis was used to identify predictors of change in HbA1c following the use of FSL. Within-person variations of HbA1c were calculated using .

RESULTS

Data were available for 10,370 FSL users (97% with type 1 diabetes), age 38.0 (±18.8) years, 51% female, diabetes duration 16.0 (±49.9) years, and BMI of 25.2 (±16.5) kg/m2 (mean [±SD]). FSL users demonstrated a −5.2 mmol/mol change in HbA1c, reducing from 67.5 (±20.9) mmol/mol (8.3%) at baseline to 62.3 (±18.5) mmol/mol (7.8%) after 7.5 (interquartile range 3.4–7.8) months of follow-up (n = 3,182) (P < 0.0001). HbA1c reduction was greater in those with initial HbA1c ≥69.5 mmol/mol (>8.5%), reducing from 85.5 (±16.1) mmol/mol (10%) to 73.1 (±15.8) mmol/mol (8.8%) (P < 0.0001). The baseline Gold score (score for hypoglycemic unawareness) was 2.7 (±1.8) and reduced to 2.4 (±1.7) (P < 0.0001) at follow-up. A total of 53% of those with a Gold score of ≥4 at baseline had a score <4 at follow-up. FSL use was also associated with a reduction in diabetes distress (P < 0.0001). FSL use was associated with a significant reduction in paramedic callouts and hospital admissions due to hypoglycemia and hyperglycemia/diabetic ketoacidosis.

CONCLUSIONS

We show that the use of FSL was associated with significantly improved glycemic control and hypoglycemia awareness and a reduction in hospital admissions.
