The radial distribution of mechanical stress, optical inhomogeneity and oxygen concentration in Sb-doped germanium crystals grown by the Czochralski method with diameter of 200 mm and resistivity from 10.5 to 18.5 Ω·cm were studied. It was found that residual stress calculated from the data of X-ray structural analysis correlates with results of numerical simulation of thermoelastic stress and interrelates with optical inhomogeneity and concentration of oxygen presented in the atomically dispersed state in germanium.

Specifics of "amorphous state - crystal" phase transitions in dependence on the samples obtaining method and thermal processing, as well as changes in the structure and close range order in the arrangement of the atoms of Ge20Sb20.5Te51 chalcogenide semiconductors have been studied by the x-ray diffraction and Raman spectroscopy. It has been shown that Ge20Sb20.5Te51 films obtained by thermal evaporation on an unheated substrate are amorphous; after heat treatment at 220 and 400 °C, transform into a crystalline phase with a cubic and hexagonal structure. The chemical bonds and the main structural elements that form the matrix of the investigated objects, as well as the changes that occur in them during heat treatment, have been determined.

Термоэлектрические свойства твердого раствора Sn1-xPbxSb4Te8 и Sn1-xPbxSb4-yBiyTe8 (y=0.4, 0.8, 1.2) измерены в широком интервале температур (100-800 K). Замещение атомов Sb атомами Bi приводит к росту коэффициента термоэдс и уменьшению решеточной составляющей теплопроводности по сравнению с соответствующими свойствами твердого раствора Sn1-xPbxSb4Te8. Более низкие значения решеточной теплопроводности в сплавах y=1.2 по сравнению с твердым раствором Sn1-xPbxSb4Te8 связаны с искажениями из-за различия атомных масс и размеров атомов Sb и Bi. При увеличении содержания Bi в твердых растворах уменьшается решеточная теплопроводность и, соответственно, увеличивается термоэлектрическая эффективность. Термоэлектрическая эффективность образца Sn1-xPbxSb4-yBiyTe8 (y=1.2) имеет максимальное значение Z=3.2·10-3 в 300 K. Ключевые слова: твердые растворы, электропроводность, термоэдс, теплопроводность, эффективность.

Во время мощной оптической пикосекундной накачки слоя GaAs гетероструктуры AlxGa1-xAs-GaAs- AlxGa1-xAs в нем возникает стимулированное пикосекундное излучение. Экспериментально выявлено, как при насыщении усиления излучения максимальная плотность энергии его спектральной компоненты и время достижения этого максимума зависят от энергии фотона, параметров усиления и релаксации компоненты. Из этих зависимостей следует, что на указанные плотность и время влияет замедление транспорта неравновесных носителей в энергетическом пространстве. Замедление вызвано взаимодействием носителей с излучением. Установлено, что при приближении к нулю диаметра активной области измеренное характерное время релаксации компоненты стремится к теоретическому универсальному остаточному времени релаксации, затянутому из-за указанного замедления транспорта. Ключевые слова: стимулированное пикосекундное излучение, арсенид галлия, спектральные компоненты излучения, коэффициент усиления, характерное время релаксации излучения, насыщение усиления, энергетический транспорт носителей заряда.

We studied the optical properties of an atomically thin WSe$_2$ film obtained by gold-assisted mechanical exfoliation. Raman scattering spectra, low-temperature photoluminescence, and micro-reflection from large-scale monolayer are investigated. At room temperature, the optical properties of such a film reproduce the properties of WSe$_2$ monolayers obtained by regular mechanical exfoliation. It is shown that at low temperatures, the radiation spectra of the resulting film are determined by standard mechanisms of radiative recombination involving free excitons, bound excitons, and trions. However, in contrast to room temperatures, there is a significant difference in the spectral width and intensity of the lines compared to monolayers WSe$_2$, obtained regular way from the same source material. The differences found, demonstrating a significant increase in background doping and structural disorder when using gold-assisted exfoliation, may be meaningful for a number of optoelectronic applications of atomically thin WSe$_2$ films.

Resonance reflection of light from the ordered arrays of silicon nanopillars (Si NP) was investigated. The height of Si NP was 450 nm. The effect of Si NP oxidation in concentrated nitric acid on the position of resonances in reflection spectra was studied. A weak influence of the additional polymeric coating on the characteristics of reflection from the structures was proven. It is established on the basis of the results of experimental investigation and direct numerical modeling by means of three-dimensional finite difference time domain algorithm (3D FDTD) that the dependence of the resonant wavelength for Si NP on the diameter of Si NP is a linear function with nonzero displacement depending on the pitch.

The dependence of iodine incorporation in CdTe layers on the deposition conditions during metalorganic vapor phase epitaxy is investigated. The growth of the layers was carried out from dimethylcadmium and diethyltellurium in the hydrogen flow in a vertical reactor with a hot wall condition at a total pressure of 20 kPa. The total iodine concentration was determined by secondary ion mass spectrometry, the electrically active concentration was determined from the Hall effect measurement. The iodine incorporation depends on the crystallographic orientation of the substrate (were studied (100), (310), (111)A, (111)B, (211)A and (211)B), the concentration of the doping precursor (flux range 5·10–8–3·10–6 mol/min), the mole ratio of organometallic compounds (DMCd/DETe=0.25–4), growth temperature (335–390°C) and the walls of the reactor above the pedestal (hot wall zone 290–320°C). The total iodine concentration reached 5·1018 cm–3 and the activation efficiency was ~4 %. After thermal annealing in cadmium vapor at 500°C the activation efficiency was ~100 %.

The design of the heterostructure of a 2.5 THz range quantum-cascade detector is proposed and heterostructure is grown by molecular-beam epitaxy technique. To optimize the thicknesses of the layers of the heterostructure cascades, a numerical method for iterative solution of the Schrodinger ¨ −Poisson
equation in the k · p formalism was used. The grown heterostructure of the quantum-cascade detector showed a high structural perfection, confirmed by the small values of the average FWHM of the high-order satellite peaks on the X-ray diffraction rocking curves, which were (8.3 ± 0.5)′′. Analysis of dark-field images obtained by transmission electron microscopy showed that the total thickness of the layers in the cascade is (137.3 ± 6.9) nm, which corresponds to the calculated thickness of the layers in the cascade of the heterostructure of the quantum-cascade detector.

Using numerical simulation, a search is carried out for designs of asymmetric barrier layers (ABLs) for a laser diode having GaAs waveguide and emitting at the wavelength λ = 980 nm. A pair of ABLs, adjoining the active region on both sides, blocks undesired charge carrier flows and suppresses parasitic spontaneous recombination in the waveguide layers. Optimal designs of ABLs based on AlGaAsSb and GaInP for blocking electrons and holes, respectively, are proposed that make it possible to reduce the parasitic recombination current down to less than 1% of the initial value. To suppress electron transport, an alternative structure based on three identical AlInAs barriers is also proposed. The GaAsP spacers separating these barriers from each other have different thicknesses. Due to this, its own set of quasi-bound (resonant) states is formed in each spacer that is different from the neighbor spacer set of states. As a result of this, the resonant tunneling channels are blocked: the parasitic electron flow is reduced by several tens of times in comparison with the case of spacers of equal thickness.

Abstract Single-layer Sb2Te3 films and three-layer Sb2Te3/Sb2S3/Sb2Te3 structures are obtained by thermal vacuum deposition. Their thermoelectric characteristics have been investigated in a wide temperature range (5350 K). It is shown that the conductivity of Sb2Te3/Sb2S3/Sb2Te3 has a semiconductor behavior, the resistivity is an order of magnitude higher than the resistivity of the Sb2Te3 film; the Seebeck coefficient of Sb2Te3/Sb2S3/Sb2Te3 is 1.5 and 3 times higher than the Seebeck coefficient of the film and single-crystal Sb2Te3, respectively. The currentvoltage characteristics of the Sb2Te3 film exhibit memristive properties with unipolar resistive switching, whereas Sb2Te3/Sb2S3/Sb2Te3 can be considered as a memristor with a parallel connected capacitance.

The 21st Century Cures Act and Multiuser Electronic Health Record Access: Potential Pitfalls of Information Release
Authors: Arvisais-Anhalt Simone , Lau May , Lehmann Christoph U , Holmgren A Jay , Medford Richard J , Ramirez Charina M , Chen Clifford N
Published: December 2021

Although the Office of The National Coordinator for Health Information Technology’s (ONC) Information Blocking Provision in the Cures Act Final Rule is an important step forward in providing patients free and unfettered access to their electronic health information (EHI), in the contexts of multiuser electronic health record (EHR) access and proxy access, concerns on the potential for harm in adolescent care contexts exist. We describe how the provision could erode patients’ (both adolescent and older patients alike) trust and willingness to seek care. The rule’s preventing harm exception does not apply to situations where the patient is a minor and the health care provider wishes to restrict a parent’s or guardian’s access to the minor’s EHI to avoid violating the minor’s confidentiality and potentially harming patient-clinician trust. This may violate previously developed government principles in the design and implementation of EHRs for pediatric care. Creating legally acceptable workarounds by means such as duplicate “shadow charting” will be burdensome (and prohibitive) for health care providers. Under the privacy exception, patients have the opportunity to request information to not be shared; however, depending on institutional practices, providers and patients may have limited awareness of this exception. Notably, the privacy exception states that providers cannot “improperly encourage or induce a patient’s request to block information.” Fearing being found in violation of the information blocking provisions, providers may feel that they are unable to guide patients navigating the release of their EHI in the multiuser or proxy access setting. ONC should provide more detailed guidance on their website and targeted outreach to providers and their specialty organizations that care for adolescents and other individuals affected by the Cures Act, and researchers should carefully monitor charting habits in these multiuser or proxy access situations.
Consistency and Sensitivity Evaluation of the Saudi Arabia Mental Health Surveillance System (MHSS): Hypothesis Generation and Testing (Preprint)
Authors: Althumiri Nora A , Basyouni Mada H , BinDhim Nasser F
Published: December 2021

BACKGROUND

Public health surveillance systems should be evaluated periodically, and the evaluation should include recommendations for improving the system’s quality and efficiency. Each surveillance system may have a unique situation in which evaluating its quality depends on its methodology, aims, and other factors, such as the frequency of repeating the survey in the case of survey-based surveillance.

OBJECTIVE

As the consistency of the surveillance system to capture demographic data and its sensitivity to monitor the intended health-related event are important indicators of the quality of the surveillance system, the aim of this article is to evaluate the Saudi Arabia Mental Health Surveillance System (MHSS) in terms of consistency and sensitivity via the scientific hypothesis testing process.

METHODS

The quality of the MHSS was assessed by examining (1) the consistency of the main demographic variables and (2) the sensitivity to changes in score between the 2 mental health screening tools used in the MHSS and between the 3 waves collected in 3 consecutive months. The assessment uses all data collected via the MHSS between May 2020 and July 2020. The first null hypothesis predicted there were differences between the distributions of the demographic variables between the 3 waves. The second predicted there were no differences between the scores of the Patient Health Questionnaire 9 (PHQ-9) and the Generalized Anxiety Disorder 7-item scale (GAD-7) between the 3 waves.

RESULTS

In terms of sampling variables (age, gender, and region), there were no significant differences between the 3 waves in age, using one-way ANOVA, nor in gender and region, using the chi-square test. In addition, there were no significant differences between the 3 waves in all other demographic variables, except in the income variable. However, in terms of the PHQ-9 score, the one-way ANOVA (F2,12334=8.05; P<.001) showed significant differences between waves. Similarly, significant differences between waves were found in the GAD-7 score (F2,12334=7.09; P=.001).

CONCLUSIONS

The MHSS showed a consistent distribution of the sample demographic variables, while being sensitive to the changes in mental health scores across waves. The MHSS can generate an acceptable level of consistency and sensitivity to monitor mental health trends.

The Fintech company has raised its number significantly in Indonesia and threatened the banking sector as Islamic Banking is not the exception. Fintech can provide better financial services than Islamic Bank with its technological advantages. This research aims to observe the effect of Fintech's on Islamic banks and discover the collaboration model between Fintech and Islamic banks to improve financial services. The method was carried out by Systematic Literature Review (SLR), then analyzed using Nvivo 12 to quantify the words counted to the papers found. The result showed that there were 14 papers found to analyze in the systematic review. According to Nvivo 12 words counted result, the highest words counted was ‘services’ with 21%, followed by ‘user’ and ‘customers’ combined with 16%. Furthermore, Fintech acts as the disruptor for Islamic Banking, shown in its Return on Asset and its potential to take over the millennial customers segment. The collaboration can be done by sharing product marketing, loans, and transaction services. For the customer, big data analysis, the legal aspects, risk of human error, and data security protocol should be mitigated by tightening the registration system to minimize fraud, enhancing the internet server to prevent failure transactions, and closely cooperating with the Authority of Financial Service in Indonesia (OJK) to ensure the legal aspects are fulfilled.

Published: December 2021

Underground economic activity is a situation that needs particular and ongoing attention. This tendency is detrimental to municipal income and is associated with corrupt behaviors and taxation. The purpose of this investigation is to identify and assess the practices of the underground economy, as well as the potential for corrupt conduct and tax evasion. The analytical tool was perhaps a qualitative method with a chosen strategy to identify knowledge sources (respondents) with subjects such as liquor producers, coffee shops, and street food vendors in the Bengkayang border area. The data collection method was carried out using a triangulation approach, namely an in-depth interview, observation, and recording/documentation. The data analysis approach was conducted using data reduction, data presentation, and verification. This study suggests that the presence of corrupt activity in collecting bribes and offering bribes is carried out in cash without going through an automated money processing mechanism such as giving false receipts. Increasing the level of corruption in society will contribute to an increase in the velocity of money. The need for massive surveillance of individuals and the introduction of Penta helix elements to shape synergies between actors and to start integrating and developing electronic/digital structures in any financial activity using the e-government system.

Authors: Nairobi Nairobi , Firdaus Muhammad Afif , Afif Fadeli Yusuf
Published: December 2021

The decline in economic growth, which is offset by the increasing number of people and the lack of availability of jobs, has caused more people to be affected and involved in non-crime activities based on the crime rate (CR). This study aims to analyze the effect of crime rates on provincial economic growth in Indonesia in 2011-2020. The variables used are economic growth, crime rates, investment, labor, and initial growth. The method used is the Fixed Effect Model. The results show that the higher the crime rate impacts the decline in economic growth, further increase in investment and labor will encourage economic growth. In contrast, the initial growth shows that the economy of poor provinces grows slower than rich provinces.

Published: December 2021

Conventional approach of establishing soil conservation strategies in
degraded drylands has had negligible success. This has been contributed
by many constraints, including; lagging of farmers in technology
adoption, inadequate resources, and lack of motivation. Thus, a study
was conducted among three agro-pastoral community farmer groups in
Korellach Parak, Kapkitony, and Kaporowo villages domiciled in
Chepareria ward, West Pokot, Kenya, to assess contributory factors and
consequences of adopting terracing as a soil conservation measure. Mixed
methods comprising; one-on-one interviews, cross-sectional field
measurements, and focus group discussions (FGDs), were used for data
collection. Results indicate that the agro-pastoral communities are
fully aware of soil degradation and its impacts. Besides terracing,
farmers practice stone bands, enclosures, agroforestry, and ridges.
Terracing is a recently adopted farm-level soil conservation practice
achieved through organized farmer groups dubbed “Kemorokorenyo”
(meaning let us reclaim our land) merry-go-round. Within the three
villages, 60% of the households have their farms terraced with an
average terrace volume of 103.8±21.45m3, 105.89±33.126m3, and
129.6±15.966m3 in Parak Kapkitony and Kaporowo, respectively. Rapid
sedimentation of terraces dykes, which contributes to the reduced
effectiveness of the terrace system was identified as the major
challenge. The sediment volume significantly differs along the slope,
with the highest sediment build-up experienced on high slopes as shown
by the Kruskal Wallis test; H (2) =6.699, p=0.035. Terrace embankments
reinforcement practice to counter sedimentation challenge has faced slow
adoption. The poor reinforcement is attributable to the lack of
knowledge on suitable local context multipurpose materials to meet the
community’s needs.

comprehensively. From 2020 to October 2021, 82 NADC34-like PRRSV
isolates were obtained from 433 PRRSV-positive clinical samples. These
strains accounted for 11.5% and 28.6% of positives in 2020 and 2021,
respectively, and have spread to eight provinces. We selected 15 samples
for whole-genome sequencing, revealing genome lengths of 15,009 to
15,113 nt. Phylogenetic analysis revealed that Chinese NADC34-like
strains cluster with American sublineage 1.5 strains and do not form an
independent branch. Recombination analysis revealed that six of fifteen
complete genome sequences derived from recombination between NADC34-like
and NADC30-like or HP-PRRSV; they all recombined with local strains in
China, exhibiting a complex recombination pattern. Partial Nsp2 sequence
alignment showed that nine of fifteen isolates have a continuous 100-aa
deletion (similar to IA/2014/NADC34); other isolates have a 131-aa
discontinuity deletion (similar to NADC30). Five of them also have
additional amino acid deletions, all of which are reported for the first
time here. In the last two years, NADC34-like PRRSV has become one of
the main epidemic strains in some areas of China; it has changed
significantly, its homology has decreased significantly, and it has
undergone complex recombination with local Chinese strains. These
results are of great significance for understanding the current epidemic
situation of PRRSV in China.

Published: December 2021

Background: Implantable cardioverter defibrillators (ICD) are
indicated for primary and secondary prevention of sudden cardiac arrest.
Despite enhancements in design and technologies, the ICD lead is the
most vulnerable component of the ICD system and failure of ICD leads
remains a significant clinical problem. A novel, small diameter,
lumenless, catheter delivered, defibrillator lead was developed with the
aim to improve long term reliability. Methods and Results: The
Lead Evaluation for Defibrillation and Reliability (LEADR) study is a
multi-center, single-arm, Bayesian, adaptive design, pre-market
interventional pivotal clinical study. Up to 60 study sites from around
the world will participate in the study. Patients indicated for a de
novo ICD will undergo defibrillation testing at implantation and
clinical assessments at baseline, implant, pre-hospital discharge, 3
months, 6 months, and every 6 months thereafter until official study
closure. Patients will participate for a minimum of 18 months to
approximately 3 years. Fracture-free survival will be evaluated using a
Bayesian statistical method that incorporates both virtual patient data
(combination of bench testing to failure with in-vivo use condition
data) with clinical patients. The clinical subject sample size will be
determined using decision rules for number of subject enrollments and
follow-up time based upon the observed number of fractures at certain
time points in the study. The adaptive study design will therefore
result in a minimum of 500 and a maximum of 900 patients enrolled.
Conclusion: The LEADR Clinical Study was designed to
efficiently provide evidence for short- and long-term safety and
efficacy of a novel lead design using Bayesian methods including a novel
virtual patient approach.

Background: Community-acquired bacterial pneumonia (CABP) remains a global public health threat and is a leading cause of hospitalization and infection-linked mortality. Levonadifloxacin is a novel benzoquinolizine antibiotic with a broad-spectrum activity including methicillin-resistant Staphylococcus aureus (MRSA) and CABP-pathogens. Methods: This multi-centre, retrospective, post-marketing, real-world study assessed the efficacy and safety of levonadifloxacin oral and/or intravenous therapy in the treatment of CABP. Data from 338 patients above 17 years-of-age who received levonadifloxacin (oral or intravenous or both) was collected from 89 healthcare facilities across India. Information on clinical condition, comorbidities, complications, and details of concurrent therapy (including antimicrobial agents) was also collected. Study outcomes were clinical and microbial success at the end of therapy while safety was assessed based on clinical and laboratory adverse events. Results: Of the 338 patients, 244 (72.2%) were male, 93 (27.5%) were female and 1 (0.43%) was a transgender. About 294 (87.0%) patients were hospital-treated and 44 (13%) received outpatient treatment. About 248 (73.4%) patients received intravenous levonadifloxacin treatment, 79 (23.4%) received oral and 11 (3.3%) received intravenous followed by oral levonadifloxacin therapy. The common comorbid conditions were diabetes (14.2%) and hypertension (8.6%). Mean duration of levonadifloxacin therapy was 6.4 days. Clinical and microbial success in levonadifloxacin-treated patients was 95.0% (321/388) and 96.8% (150/155), respectively. Conclusions: Levonadifloxacin showed promising clinical outcomes and safety when used as an intravenous and/or oral for the treatment of CABP, both in outpatients as well as hospitalized patients.
