Показано, что при одновременном и последовательном осаждении пленок системы Cu2Te-In2Te3, а также используемых в качестве исходных материалов меди, индия и теллура высшей очистки ~99.999%, взятых в соотношениях Cu : In : Te = 1 : 5 : 8, независимо от порядка напыления выделяются тройные соединения составов CuInTe2, CuIn3Te5 и CuIn5Te8 в кристаллическом состоянии. При вакуумной конденсации пленок на монокристаллические подложки NaCl, KCl и аморфный целлулоид, охлажденные жидким азотом до 203 K, образующиеся пленки, полученные как совместным испарением двойных соединений системы Cu2Te-In2Te3, так и синтезом тонких слоев, примененных Cu, In, Te, являются аморфными. Впервые в наноразмерных аморфных пленках состава CuIn5Te8, кристаллизующихся в тетрагональной сингонии с периодами элементарных ячеек a=6.162 Angstrem, c=12.291 Angstrem, полученных как в обычных условиях, так и в условиях воздействия внешнего электрического поля напряженностью 500 В · см-1, установлена структура ближнего атомного порядка --- число ближайших соседей, координационные числа и радиусы координационных сфер. Выявлено, что в аморфных пленках CuIn5Te8, полученных в условиях воздействия внешнего электрического поля, в которых матрицы состоят из тетраэдрических и октаэдрических окружений атомов, в отличие от пленок, формирующихся без воздействия поля, число ближайших соседей, оставаясь неизменным, радиусы координационных сфер и межатомные расстояния несколько укорачиваются. Ключевые слова: фазообразование, электронограмма, функция радиального распределения атомов (ФРРА), когерентное рассеяние электронов.

In recent years, narrow gap heterostructures with Hg1-xCdxTe/CdyHg1-yTe quantum wells have been actively studied both in connection with the topic of topological insulators and from the point of view of their application in optoelectronics in the terahertz domain. In this work, we study the photoconductivity and photoluminescence spectra of structure with a band gap of 40 meV. In addition to interband transitions, the features of the spectra associated with the resonance states of acceptors have been identified. The possibilities of using the structures under study to develop interband emitters at a wavelength of ~ 30 μm, which is inaccessible to existing quantum-cascade lasers, are discussed.
Основные эффекты кислородных центров в оптике A-=SUP=-II-=/SUP=-B-=SUP=-VI-=/SUP=-

On the basis of the studies carried out, it is shown in the work that the influence of oxygen on the optical properties of А2В6 crystals is determined by three main effects. This is the formation of a system of bound excitons accompanying the presence of high oxygen concentrations at stacking faults — a long-wavelength shift by hundreds of meV of the absorption edge, and the third effect is determined by the emergence of broadband “self-activated” SA luminescence in the near-edge region of the spectrum. This work introduces the concept of a non-uniform distribution of isoelectronic oxygen centers in the bulk of crystals, both due to their predominant segregation at stacking faults and in these layers of stacking faults. To analyze the optical data, we used the capabilities of the method for constructing band models, which collects extensive and multilateral information about specific samples. A new refined model of the CdS ∙ O multizone with stacking faults is presented. The paper describes the conditions and the possibility of joint and separate observation of these features in the spectra of different crystals А2В6 and using them to create lasers.

A comparative analysis of various methods of forming a copper (Cu) contact grid on the surface of silicon heterojunction solar cells (SHJ SC) as an alternative to the standard screen printing method using expensive silver-containing (Ag) pastes is presented. It has been shown that the use of inkjet printing for the formation of protective dielectric masks based on an organic polymer and thin buffer metal layers for the growth of a Cu contact grid by electroplating makes it possible to form a contact grid of the required shape and having sufficient adhesion to the surface of SHJ SC. Using this method, double-sided SHJ SC (size 157x157 mm2) with Cu contact mesh were fabricated, demonstrating an efficiency of 22.9% and an adhesion level of 3–5 N/mm compared to 22.6% and 1.5–2 N/mm using a similar contact mesh based on Ag paste.

Published: March 2022

BACKGROUND

Electronic medical records (EMRs) offer the promise of computationally identifying sarcoidosis cases. However, the accuracy of identifying these cases in the EMR is unknown.

OBJECTIVE

The aim of this study is to determine the statistical performance of using the International Classification of Diseases (ICD) diagnostic codes to identify patients with sarcoidosis in the EMR.

METHODS

We used the ICD diagnostic codes to identify sarcoidosis cases by searching the EMRs of the San Francisco and Palo Alto Veterans Affairs medical centers and randomly selecting 200 patients. To improve the diagnostic accuracy of the computational algorithm in cases where histopathological data are unavailable, we developed an index of suspicion to identify cases with a high index of suspicion for sarcoidosis (confirmed and probable) based on clinical and radiographic features alone using the American Thoracic Society practice guideline. Through medical record review, we determined the positive predictive value (PPV) of diagnosing sarcoidosis by two computational methods: using ICD codes alone and using ICD codes plus the high index of suspicion.

RESULTS

Among the 200 patients, 158 (79%) had a high index of suspicion for sarcoidosis. Of these 158 patients, 142 (89.9%) had documentation of nonnecrotizing granuloma, confirming biopsy-proven sarcoidosis. The PPV of using ICD codes alone was 79% (95% CI 78.6%-80.5%) for identifying sarcoidosis cases and 71% (95% CI 64.7%-77.3%) for identifying histopathologically confirmed sarcoidosis in the EMRs. The inclusion of the generated high index of suspicion to identify confirmed sarcoidosis cases increased the PPV significantly to 100% (95% CI 96.5%-100%). Histopathology documentation alone was 90% sensitive compared with high index of suspicion.

CONCLUSIONS

ICD codes are reasonable classifiers for identifying sarcoidosis cases within EMRs with a PPV of 79%. Using a computational algorithm to capture index of suspicion data elements could significantly improve the case-identification accuracy.
Impact of the COVID-19 Pandemic on Dermatology Practice Worldwide: Results of a Survey Promoted by the International Dermoscopy Society (Preprint)
Authors: Conforti Claudio
Published: March 2022

BACKGROUND

The International Dermoscopy Society (IDS) conducted an online survey to investigate the impact of the COVID-19 outbreak on the daily practice of dermatologists working with patients with skin cancer, to collect data regarding the frequency of skin manifestations noticed by the members, and to obtain information about the use of teledermatology during the pandemic.

OBJECTIVE

The aims of this study are to identify changes within dermatology departments during lockdowns, to evaluate the use of teledermatology during the COVID-19 pandemic, and to find the most frequent cutaneous manifestations associated with COVID-19.

METHODS

All IDS members (approximately 160,000 members) were asked to fill in a questionnaire sent by email. The questionnaire was available in English and was anonymous, with a compiling time of less than 5 minutes. The survey was open for 30 days (from April 24, 2020, to May 24, 2020) and it could only be filled out once.

RESULTS

Overall, 678 dermatologists responded to the questionnaire; of these, 334 members stated that there had been a reduction of more than 75% in daily work activity during the pandemic, 265 dermatologists worked fewer days per week, and 118 experienced telemedicine for the first time. Acrodermatitis was the most frequently observed skin manifestation (n=80), followed by urticarial rash (n=69), morbilliform rash (n=53), and purpuric manifestation (n=40). Regarding the role of teledermatology, 565 dermatologists reported an increased number of teleconsultations, and the number of melanomas diagnosed during the pandemic was practically 0 for 385 (56.8%) respondents.

CONCLUSIONS

This survey highlights that the outbreak had a negative impact on most dermatology services, with a significant reduction in consultation time spent for patients with chronic conditions, and an increased risk of missed melanoma and nonmelanoma skin cancer diagnosis. Moreover, our study confirms earlier findings of a wide range of skin manifestations associated with COVID-19.

Published: March 2022

BACKGROUND

Over 325,000 mobile health (mHealth) applications (apps) are available to download across various app stores. Quality assurance in this field of medicine remains relatively undefined, however. Globally around 84% of the population have access to mobile broadband networks. Given the potential for mHealth app use in health promotion and disease prevention, their role in medicine world-wide is ever apparent. Quality assurance regulations both nationally and internationally will take time to develop. Frameworks such as the Mobile App Rating Scale (MARS) and Enlight Suite have demonstrated potential for use in the interim. These frameworks require adaptation to be suitable for use in Low and Middle-Income Countries (LMIC) however.

OBJECTIVE

1) Modify the Enlight Suite, an mHealth app quality assessment methodology, to improve its applicability internationally, and 2) to assess the preliminary validity and reliability of this modified tool in practice.

METHODS

A two-round Delphi study involving 7 mHealth experts with varied backgrounds in medicine, health and technology was conducted to modify and adapt the Enlight Suite for international use as well as to improve its content validity. The Modified Enlight suite (MES) was then used by 800 healthcare professionals and healthcare students to assess a COVID-19 tracker app in an online survey form. The reliability of the MES was assessed using the Cronbach alpha while the construct validity was evaluated using the confirmatory factor analysis.

RESULTS

The final version of the MES has 7 sections with 32 evaluating items. Of these items, 5 were novel and based on consensus for inclusion by Delphi panel members. The MES has a satisfactory reliability with an internal consistency Cronbach alpha score of 0.925. The sub-scales also demonstrate acceptable internal consistency. Similarly, the confirmatory factor analysis demonstrates a positive and significant factor loading for all of the 32 items in the MES with a modestly acceptable model fit: thus, indicating the construct validity of the MES.

CONCLUSIONS

Despite increasing use, access, and reliance on mHealth apps internationally, previous studies have failed to identify a quality assessment methodology which included factors known to hinder the use and uptake of apps in LMICs. This study indicates both the validity and initial reliability of the MES for assessing the quality of mHealth apps internationally. Further reliability assessments are required in LMICs to extrapolate these findings to seek its true potential.

Authors: Tanwani Jaya , Alam Fahad , Matava Clyde , Choi Stephen , McHardy Paul , Singer Oskar , Cheong Geraldine , Wiegelmann Julian
Published: March 2022

BACKGROUND

Neuraxial anesthesia is conventionally performed using a landmark-based technique. Preprocedural ultrasound is often used in challenging clinical scenarios to identify an ideal needle path. The procedure is then carried out by the operator recreating the ultrasound needle path from memory. We suggest that a needle guidance system using the Microsoft HoloLens mixed reality headset, which projects a hologram of the ideal needle path, can assist operators in replicating the correct needle angulation and result in fewer needle passes.

OBJECTIVE

The objective of the study was to develop software for the mixed reality HoloLens headset, which could be used to augment the performance of neuraxial anesthesia, and establish its face validity in lumbar spine phantom models.

METHODS

We developed an ultrasound transducer marker and software for the HoloLens, which registers the position and angulation of the ultrasound transducer during preprocedural scans. Once an image of a clear path from skin to the intrathecal space is acquired, a hologram of the ideal needle path is projected onto the user’s visual field. The ultrasound probe is removed while the hologram remains in the correct spatial position to visualize the needle trajectory during the procedure as if conducting real-time ultrasound. User testing was performed using a lumbar spine phantom.

RESULTS

Preliminary work demonstrates that novice (2 anesthesia residents) and experienced operators (5 attending anesthesiologists) can rapidly learn to use mixed reality holograms to perform neuraxial anesthesia on lumbar spine phantoms.

CONCLUSIONS

Our study shows promising results for performing neuraxial anesthesia in phantoms using the HoloLens. Although this may have wide-ranging implications for image-guided therapies, further study is required to quantify the accuracy and safety benefit of using holographic guidance.

The Influence of Corporate Governance on the Environmental Information Disclosure of MNCs: An Empirical Study on Corporations from China, Japan, the United Kingdom and the United States
Authors: Li Chenqi , Peng Xuhui
Published: March 2022

As one of the ways for multinational companies to obtain the advantages of sustainable development, corporate social responsibility (CSR) has been widely recognized by the academic community. Research featuring the influence of corporate governance (CG) on the environmental information disclosure of multinational corporations (MNCs) have gained much attention, but there is a lack of research into the empirical examination of cross-national samples. Drawing on Agency Theory, this study fills the gap by making a theoretical exploration and empirical test on relationships between CG and MNCs’s environmental disclosure. Board independence, board size, board meeting frequency and their relationships to the environmental disclosure of MNCs are observed in this study. In order to examine the aforementioned relationships, this study incorporates measurement techniques used by Van Staden and Hooks (2007) [1] and Global Reporting Initiative 4.0 guideline (GRI4.0) and develops a set of comprehensive, systematic measurement standards to appraise the environmental information disclosure of corporations. The content analysis method is used to assess the environmental disclosure of 151 companies from China, the United States, Japan, and the United Kingdom, according to Forbes Global 2000 Ranking in 2019. We find that board independence, the board size, and the frequency of board meetings are all positively associated with the environmental disclosure of MNCs. This finding indicates that more independent boards of directors, larger boards, and more frequent board meetings are CG mechanisms which lower the likelihood for an opportunistic behaviour and increase information transparency and voluntary implementation of the disclosure, effectively enhancing the environmental disclosure of MNCs. This impact of CG on corporations’ environmental information disclosure exists across country contexts.
Determinants of Productivity in Brazil: An empirical analysis of the period 1996-2021
Authors: Tadeu Hugo Ferreira Braga , Silva Jersone Tasso Moreira
Published: March 2022

Empirical studies regarding the determinants of productivity in developing countries, including Brazil, have demonstrated the negative impact of high inflation rates on the industrial capacity. However, the recent Brazilian experience clearly shows that stabilization since 1996, in and of itself, is not capable of recovering the investment rates. With this in mind, this study's goal is to answer, with the help of econometric simulation models, the questions: (i) what are the key-drivers to assess the Brazilian economy since 1996?; and (ii) what are the key-factors to be considered when investments are made, particulary in productivity? To answer the questions we evaluated the impacts of macro-economic variables on private investments, using a strategic bias and a long term vision plan. The estimates demonstrate empirical crowding-in evidence of public investments in infrastructure over private investments as a real impact to productivity. As for public invetsments (non-infrastructural) we suggest that the crowding-in impact dislocates private investments. All these indicators were obtained as presented in the therory, with the exception of the real interest rates variable (r), in which we observed that the coefficient is positive and insignificant in the estimated equation.

Abstract: The main function of this robot is to remove the unwanted tiny plants or grass from the main crop, this system is very useful for farmer which avoids lot of manual work. Plucking weeds manually is very painful activity and also consumes lot of time and therefore this mechanism is designed. Since it is a prototype module, basic version of grass or tiny weeds plucking mechanism is designed with spur gears. The moving mechanism is constructed with motorized wheels, for this purpose 30RPM motors are used. The mechanism is designed to move in all directions including reverse direction. The plucking mechanism designed with spur gears is attached with another motor shaft. Two spur gears are used and are meshed with each other, when the vehicle is moving and when the gears are rolling, the grass or tiny weeds will be removed by the gear mechanism. The demo module is constructed with small spur gears, with this the basic concept can be proved and it is not a full fledged mechanism. With the help of a remote control unit constructed with 12E, 12D chips & RF transmitter, entire machine can be controlled. H Bridge IC is used to drive the wheel drive motors through remote and weed picking mechanism must be activated manually through third DC motor. Moving mechanism is controlled through 2 DC motors and is controlled independently by which mechanism will be moved in all directions. 12V, 1Ah Rechargeable battery is used to run the entire system and this battery can be charged through ac adapter. The remote is constructed using four keys to move the robot forward, reverse, right and left directions. By pressing any control key in the remote unit, the encoder chip generates proportionate digital code, which is fed to the RF transmitter for transmitting the data. In the receiver, the received data will be decoded by the 12D IC and based on this code this chip enables the H Bridge IC by which the corresponding motor rotates in one direction. Likewise both DC motors will be controlled independently according to the command code received by the communication system.

Published: March 2022

LoRa Technology is one of the devices used on Low-Power Wide Area Networks (LPWAN), which is a viable alternative wireless communication technology for the Internet of Things (IoT). The LoRa device is meant to traverse a large distance while using minimal power. However, because it uses single-hop communication, the Gateway's farthest nodes will die prematurely as a result of the increased energy usage. This research attempts to improve the range of LoRa networks utilizing multi-hop uplink communication while also reducing energy consumption by adjusting the LoRa transmission power to the lowest possible dBm in each hop. As a network model, a star topology-based tree made of some rings with a gateway as the central point is chosen. The performance of two forms of uplink communication, single-hop and multi-hop models was tested in terms of energy consumption and coverage. The results show that the network structure in the multi-hop uplink model can extend coverage over a greater distance while using less energy than the single-hop uplink model. This model can be used as a supplement to the LPWAN's uplink communication in the IoT to enhance the network's coverage range and lifetime.

Published: March 2022

Objeto deste trabalho são três experiências participativas locais, com atenção para as estratégias adotadas por grupos do Recôncavo da Bahia para a salvaguarda de suas manifestações culturais, numa complexa e contraditória relação com o Estado. O reconhecimento do Samba de Roda (2004), do Bembé do Mercado (2012) e das Cheganças, Marujadas e Embaixadas (2019), manifestações de grupos subalternizados, como patrimônio cultural pelo poder público foi um marco e o processo de patrimonialização merece atenção, uma vez que ele se inicia a partir de tentativas do poder público de induzir a participação popular, com riscos de domesticação e disciplinamento. Assumindo uma perspectiva situada e considerando a ideia de cidadania cultural, optamos por uma abordagem que nos levou a identificar os protagonistas dos processos descritos, focando em suas motivações e sua capacidade de agência. A pesquisa mostra que os processos de patrimonialização em tela significaram, para os grupos envolvidos, uma estratégia de empoderamento, um caminho para aprofundar os processos de mobilização e de organização coletiva em busca de protagonismo na condução de suas manifestações culturais.

A prática de ensino supervisionada do futuro professor é um período determinante para o desenvolvimento das suas práticas educativas e competências profissionais. Apesar de valorizarem a sua natureza ativa e interdisciplinar, muitos professores têm demonstrado dificuldades em implementar o Trabalho de Projeto nas suas práticas. Este estudo visa conhecer a forma como os futuros professores do 1.º Ciclo do Ensino Básico, em Portugal, integram o Trabalho de Projeto nos seus estágios de prática pedagógica. Os dados foram recolhidos através de entrevistas em grupo focal a dois grupos de estudantes de instituições diferentes, mas com modelos de formação semelhantes. Os resultados demonstram que os futuros professores valorizam e procuram contemplar o Trabalho de Projeto nas suas práticas educativas, atravessando algumas dificuldades na implementação desta metodologia, que poderiam ser atenuadas através de uma maior concertação entre a instituição formadora e as escolas de estágio, de modo a minimizar o hiato existente entre os modelos pedagógicos abordados na formação e as realidades educativas encontradas.

Authors: Rivas Iván Martínez , Chichón José Luis Estrada
Published: March 2022

El interés por el factor nativo en la enseñanza del inglés es reciente, siendo el trabajo de Medgyes (1992) el punto de partida. Diversas investigaciones han tratado las preferencias de alumnos y docentes, aunque ningún estudio ha investigado esta variable en Galicia (España), y, más específicamente, en Bachillerato (16-18 años). Por ello, este artículo pretende contribuir a la literatura específica existente, analizando las actitudes y preferencias de estudiantes (n=101) y docentes (n=6) ante profesores de inglés nativos y no nativos en dos cursos de Bachillerato y en dos centros educativos distintos de Galicia. Los datos se obtuvieron mediante un cuestionario (LASAGABASTER; SIERRA, 2005) y dos grupos focales con una parte de los estudiantes (n=12) y docentes (n=6) encuestados, respectivamente, combinando métodos cuantitativos y cualitativos. Los resultados revelan una tendencia general a favor de los profesores de inglés nativos que va afianzándose según los alumnos progresan por las etapas educativas: educación primaria, secundaria y terciaria. Además, en cuanto a la preferencia de las áreas lingüísticas, se opta por el profesorado no-nativo para la enseñanza de la gramática y cuestiones de evaluación, siendo superado por el profesorado nativo en el resto de las áreas.
