Authors: Permynov Y. , Monakhov E. 
Published: September 2019

В статье показана целесообразность использования серийных асинхронных двигателей при создании синхронных генераторов с возбуждением от постоянных магнитов. По результатам расчетов даны рекомендации по выбору асинхронных двигателей и соответствующих мультипликаторов при изготовлении синхронных генераторов с возбуждением от высокоэнергетических редкоземельных постоянных магнитов неодим – железо – бор (NdFeB). Применение мультипликатора позволяет повысить частоту вращения генератора, уменьшить его габариты, массу, однако это вызывает увеличение общей массы установки за счет применения мультипликатора. Серийные изделия отличаются оптимальными геометрическими соотношениями, минимизированы по массе, отличаются качеством изготовления, и, следовательно, – надежностью. В работе предложена оригинальная конструкция бескорпусного, безредукторного синхронного магнитоэлектрического генератора для ветроустановок и приведены некоторые результаты расчетов ряда генераторов на базе этой конструкции мощностью от 20 кВт до 2 МВт, а также дана оценка характера изменения геометрических размеров зубцовой зоны статоров в этих генераторах, которая позволяет оценить технологичность их изготовления. Для снижения массо-габаритных показателей был предложен, разработан, изготовлен и испытан бескорпусной безредукторный синхронный генератор с возбуждением от постоянных магнитов мощностью 20 кВт. Также в работе представлены некоторые результаты расчетов редукторной и безредукторной компоновки ветроустановки для их последующей оценки, учитывая габариты и массу активных материалов, в том числе редкоземельных постоянных магнитов, цена которых является наибольшей.

A simple STAR Element Repetitive-PCR (SER-PCR) typing method for the rapid characterization of Staphylococcus aureus
Authors: Al-Zahrani Ibrahim A 
Published: September 2019

Introduction: Staphylococcus aureus repeat (STAR) elements are abundant repeat sequences that are highly variable in numbers and locations within the genome of S. aureus. The evolutionary variation of these repeats occurs rapidly over time and may correlate with their evolutionary lineage. Therefore, the aim of this study is to analyze STAR elements to develop a simple PCR-based typing technique that can be used routinely in clinical laboratories.
Methodology: The genomes of 10 reference strains of S. aureus were analyzed to identify the number and location of STAR elements. One pair of PCR primers was designed to target the variable region of these elements. The designed primers were first evaluated against 13 well-known reference strains of S. aureus and eventually evaluated against 40 well-characterized clinical isolates.
Results: STAR element repetitive-PCR (SER-PCR) showed good typeability with acceptable discriminatory power against the reference and clinical strains. The new method clearly differentiated between community-associated methicillin-resistant S. aureus (CA-MRSA) and hospital-associated (HA-MRSA) strains. Phylogenetic analysis of the SER-PCR patterns and multilocus sequence typing (MLST) data showed good correlation between the two methods.
Conclusions: This study provides a simple genotyping method for S. aureus based on the variation of the amplicon size of a single set of primers and rapidly extracted DNA. The method is rapid with acceptable discriminatory power and does not require a sophisticated apparatus or special expertise. The results suggest that SER-PCR could be routinely useful in any clinical microbiology laboratory, particularly in developing countries.

Abstract. Herein, we present a description of the Mechanism of Intermediate
complexity for Modelling Iron (MIMI v1.0). This iron processing module was
developed for use within Earth system models and has been updated within a
modal aerosol framework from the original implementation in a bulk aerosol
model. MIMI simulates the emission and atmospheric processing of two main
sources of iron in aerosol prior to deposition: mineral dust and combustion
processes. Atmospheric dissolution of insoluble to soluble iron is
parameterized by an acidic interstitial aerosol reaction and a separate
in-cloud aerosol reaction scheme based on observations of enhanced aerosol
iron solubility in the presence of oxalate. Updates include a more
comprehensive treatment of combustion iron emissions, improvements to the
iron dissolution scheme, and an improved physical dust mobilization scheme.
An extensive dataset consisting predominantly of cruise-based observations
was compiled to compare to the model. The annual mean modelled concentration
of surface-level total iron compared well with observations but less so in
the soluble fraction (iron solubility) for which observations are much more
variable in space and time. Comparing model and observational data is
sensitive to the definition of the average as well as the temporal and spatial
range over which it is calculated. Through statistical analysis and
examples, we show that a median or log-normal distribution is preferred when
comparing with soluble iron observations. The iron solubility
calculated at each model time step versus that calculated based on a ratio
of the monthly mean values, which is routinely presented in aerosol studies
and used in ocean biogeochemistry models, is on average globally one-third
(34 %) higher. We redefined ocean deposition regions based on dominant
iron emission sources and found that the daily variability in soluble iron
simulated by MIMI was larger than that of previous model simulations. MIMI
simulated a general increase in soluble iron deposition to Southern
Hemisphere oceans by a factor of 2 to 4 compared with the previous
version, which has implications for our understanding of the ocean
biogeochemistry of these predominantly iron-limited ocean regions.

Published: September 2019

Abstract. Differential pressure flowmeters are commonly used in industrial applications where, however, the upstream flow conditions are usually highly disturbed, caused by the presence, in the network pipe, of elbows, valves, etc. To achieve accurate flow measurements, the use of the cone meter is recommended as the flowmeter has the property to normalize the flow both upstream and downstream. In this paper, the authors present a cone flowmeter of new geometry that allows them to obtain better performance with respect to the original one; in particular, it provides a higher discharge coefficient (Cd) for a wider range of operating conditions.

ImportanceThe American Heart Association proposed Life’s Essential 8 (LE8) as an enhanced measurement tool for cardiovascular health.ObjectiveTo examine the association of LE8 with risk of atherosclerotic cardiovascular disease (ASCVD) incidence and prognosis in veterans.Design, Setting, and ParticipantsThis was a prospective cohort study of US veterans enrolled in the Department of Veterans Affairs (VA) Million Veteran Program (MVP) between 2011 and 2022. Data were analyzed from 2023 to 2024.ExposureLE8 score ranged from 0 to 100, with higher score indicating better cardiovascular health.Main Outcomes and MeasuresThe primary outcome was total ASCVD incidence in veterans without baseline ASCVD, and the secondary outcome was incidence of a major adverse cardiovascular event (MACE) among veterans with and without ASCVD at baseline.ResultsA total of 413 052 veterans (mean [SD] age, 65.8 [12.1] years; 378 162 [91.6%] male) were included. Based on 1.7 million person-years of follow-up of 279 868 veterans without any ASCVD at baseline, 45 067 veterans had an ASCVD event during follow-up. Total LE8 score and each component LE8 factor score was associated with incident ASCVD in an inverse, linear, dose-response manner. For veterans without prior ASCVD, those with an LE8 score between 80 and 100 had lower risk of ASCVD compared with those with an LE8 score of 0 to 49 (adjusted hazard ratio [aHR], 0.36 [95% CI, 0.35-0.38]). Similarly, risk of MACE was significantly lower among veterans with an LE8 score of 80 to 100 regardless of baseline ASCVD status (with ASCVD: aHR, 0.52 [95% CI, 0.48-0.56]; without ASCVD: aHR, 0.14 [95% CI, 0.13-0.15]) compared with those with ASCVD and an LE8 score of 0 to 49.Conclusions and RelevanceIn this cohort study of US veterans, higher LE8 scores were associated with significantly lower ASCVD incidence risk and lower likelihood of developing adverse cardiovascular events regardless of ASCVD status at baseline. These results support the utility of LE8 for health promotion and ASCVD prevention.

Published: December 2024

AbstractVan der Waals (vdWs) heterostructures enable the fabrication of various optoelectronic devices with unprecedented functionalities, particularly antiambipolar transistors. Different methods have been employed to construct such devices; however, their integration and versatility remain significantly constrained. Here, large‐scale antiambipolar vdWs heterostructure arrays capable of implementing self‐adaptive artificial perception systems and reconfigurable logic gates are verified adopting 2D Te/WS2 heterojunctions for the first time. The resulting transistors allow the modulation of band slope and depletion regions in individual constituents through electrostatic gating, delivering a high rectification ratio of 1.8 × 104. Benefiting from the gate‐tunable antiambipolar characteristic and charge capture, such a device can realize reconfigurable modulation of synaptic plasticity between excitatory and inhibitory modes, enabling the emulation of artificial perception system for the adaptive and subjective perception adjustment in various external environments and also a recognition accuracy of 90.5% for image classification through training and inference simulations. In addition, five fundamental logic gate operations with good stability and reliability, as well as low energy consumption, are achieved in the dual‐gate antiambipolar transistor by tuning the input signals. Furthermore, similar antiambipolar characteristics are also observed from other 2D Te‐based heterostructures, defining a simple, effective, and universal method to create multifunctional antiambipolar transistors.
Piperazine‐Functionalized Arylene Diimides as Electron Transport Layers for High‐Efficiency and Stable Organic Solar Cells
Authors: Li Yi , Wang Lixin , Fu Huiting , Zheng Qingdong 
Published: December 2024

AbstractIn organic solar cells (OSCs), electron transport layer (ETL) materials are typically designed with highly polar groups to lower the work function (WF) of the cathode and ensure solvent orthogonality. However, the increased surface energy associated with these polar groups results in significant hygroscopicity and poor interfacial contact with the active layer, posing a challenge for interlayer engineering that must balance device efficiency and stability. Herein, two novel arylene diimides (PDI‐P and NDI‐P) are developed with side chains that are end‐capped with piperazine groups, as opposed to the commonly used amine groups. As ETLs, these materials not only exhibit excellent electron conductivity but also effectively lower the WF of the silver cathode. Compared to the amine‐functionalized perylene diimide (PDI‐N), the piperazine‐functionalized perylene diimide (PDI‐P) exhibits reduced surface energy and hygroscopicity, resulting in improved wettability with the active layer and decreased moisture sensitivity. These characteristics contribute to enhanced interfacial contact and device stability. The PDI‐P ETL is compatible with various high‐performance electron acceptor materials, achieving high efficiencies across a wide thickness range of ≈7 to 30 nm, with a maximum efficiency of 19.8%. These findings highlight the great potential of PDI‐P as an ETL for high‐efficiency and stable OSCs.

Published: December 2024

AbstractThe maintenance of triplet excitons to produce room‐temperature phosphorescence while simultaneously improving the luminescence dissymmetry factor (glum) and photoluminescence quantum yield (PLQY) makes the preparation of circularly polarized room‐temperature phosphorescence (CP‐RTP) materials challenging. Herein, two chiral cocrystals are reported with CP‐RTP using S/R‐1‐(1‐Naphthyl)ethanol (S/R‐1‐nea) as the donor and 1,2,4,5‐Tetracyanobenzene (TCNB) as the acceptor. Simultaneous enhancement of glum and PLQY is accomplished, with the greatest phosphorescence in the PLQY of ≈31% and |glum| of 0.065, which is one of the highest |glum| in cocrystals. Doping two chiral cocrystals into the polyvinyl alcohol (PVA) matrix resulted in polymer films with circularly polarized long afterglow luminescence, indicating the potential for multilevel encryption applications. This study provides a novel approach to achieve the dual improvement of glum and phosphorescence PLQY, and broadens the application prospects of CP‐RTP materials.

Published: December 2024

AbstractChiral materials exhibit distinctive properties that improve the performance of organic solar cells (OSCs). In this study, chiral PM6 is integrated into PM6:PY‐IT blends to fabricate chiral quasi‐binary OSCs (cOSCs). The produced devices displayed an increased short‐circuit current and fill factor, achieving a peak efficiency of 16.60% compared to 15.96% for the standard PM6:PY‐IT cell. Additionally, the incorporation of chiral PM6 significantly enhanced the thermal stability, with the cOSCs retaining over 80% of their initial efficiency after 1000 h of operation. The steric effect of chiral PM6 altered the molecular packing, thereby improving the overall crystallinity. The optimized nanoscale domain morphology resulted in a more effective blend film, leading to superior device performance. Moreover, the chirality‐induced orbital angular momentum increased the ratio of triplet states, which is a key factor for increasing the photocurrent in OSCs. The delocalization of electron wavefunctions is driven by chiral steric effects, and it diminished the Coulomb attraction between the interfacial electron–hole pairs, which enhanced the efficient charge generation. This study provides valuable insights into the role of chirality in optimizing both the performance and stability of OSCs.
Multicolor and Hydrochromic Luminescence of Alloyed Cs2CdCl4 for Advanced Information Encryption
Authors: Wang Chao , Yan Zhengguang , Ma Lin , Xiao Jiawen 
Published: December 2024

AbstractAdvanced optical information encryption usually relies on the integration of multicolor, stimulus‐responsive, and afterglow luminescence. However, achieving these simultaneously within a single‐phase system has posed challenges, complicating the design process. In this study, an advanced 3D information encryption strategy is presented based on undoped and alloyed Cs₂CdCl₄, encrypted through three distinct channels: emission wavelength, water stimulation, and afterglow time. Specifically, Mn2+, Sb3+, and Ag+ doped Cs₂CdCl₄ single crystals are successfully synthesized via a modified hydrothermal method, which exhibit bright orange, green, and blue emissions, respectively. Decryption of specific information can be achieved by employing corresponding narrowband filters. Furthermore, the Cs₂CdCl₄ system demonstrates hydrochromism, attributed to water‐induced sequential phase transitions. Upon water treatment, the 2D Cs₂CdCl₄ will undergo a phase transition to Cs3Cd2Cl7, and finally to cubic CsCdCl3. Interestingly, the resultant CsCdCl3 exhibits pronounced afterglow, originating from the triplet emission of Cd ions. Leveraging these unique properties, a highly secure and adjustable 3D encrypted quick response code is designed. The encrypted information is encoded in coordinates, and decrypted information can be retrieved in both compressed and decompressed modes as required. These findings pave the way for the development of novel smart photonic materials and multimodal optical information encryption.

Published: December 2024

AbstractRealizing air‐processed blue halide perovskite films with tailored emission is significant for promoting the commercialization of perovskite light‐emitting diodes (PeLEDs). However, the intrinsically inferior thermodynamic stability and laborious crystallization kinetics control under humidity interference limit the fabrication of blue perovskite emitters in ambient air. Here, air‐processed pure‐bromide quasi‐2D blue perovskite films are achieved with stabilized lattice and tunable emission by interstitial doping of trivalent metallic cations. This strategy improves the formation energy of the perovskite lattice, promotes energy transfer between different n phases, and suppresses intrinsic electron‐phonon coupling in the perovskite films. The emission‐controllable blue PeLEDs are fabricated in ambient air for the first time. The champion deep blue PeLED shows maximum external quantum efficiency (EQE) of 2.05% and luminance of 246.56 cd m−2, which are comparable to the state‐of‐the‐art of similar devices fabricated in glovebox. The work pioneers a simple method of electronic structure engineering to tune the emission of air‐processed blue perovskite, breaking the limitations of thermodynamic stability and crystallization kinetics control of perovskite in ambient air.

Published: December 2024

AbstractThis paper estimates the effect of short‐term changes in real consumer food prices on short‐term fluctuations in neonatal, infant, and child mortality rates using a panel dataset covering 59 low‐ and middle‐income countries (LMICs) for the period 2000–2015. Quarterly mortality rates were constructed from over 145 rounds of the standard Demographic and Health Surveys allowing to identify short‐term (<1 year) effects of food price shocks. The results indicate that rising real food prices had a large and significant effect on neonatal, infant, and child mortalities, regardless of the type of country‐specific time trends chosen.

Published: December 2024

ABSTRACTTANGO2 deficiency disorder is often underdiagnosed and lacks an optimal treatment strategy. A 7‐year‐old Chinese girl presented with epilepsy, developmental delay, neuroregression, and episodes of dyskinesia. Additionally, she lapsed into a comatose state following her the last generalized tonic–clonic seizure. Trio whole‐exome sequencing revealed compound heterozygous variants of the TANGO2 gene. Eventually, her clinical signs and symptoms significantly improved following treatment with vitamin B5. TANGO2 deficiency disorder is a severe neurodegenerative condition that can be diagnosed via trio whole‐exome sequencing. This report highlights the potential therapeutic effects of vitamin B5 against this disease and suggests that high‐dose vitamin B5 administration may be safe for the treatment of TANGO2 deficiency disorder.

Published: December 2024

ABSTRACTDermatosparaxis Ehlers Danlos syndrome (dEDS) is a very rare monogenic EDS that occurs due to biallelic pathogenic variants in ADAMTS2. Fifteen individuals with dEDS have been reported in the literature, with the oldest being 19 years at follow‐up. Given the lack of information regarding adults with dEDS, our aim was to describe adults with dEDS to inform management recommendations in adulthood. We report five individuals (2:3 male:female) with an age range of 22–42 years. Complications include extreme skin fragility resulting in iatrogenic injury, redundant skin folds often requiring surgical resection, severe complications following a gastric volvulus secondary to a diaphragmatic hernia, and multiple fractures. Discussion of management considerations includes thorough investigations of acute pain, careful consideration of skin closure techniques and manual handling, as well as monitoring for reduced bone mineral density after low‐impact fracture and/or post‐menopause.
