Abstract
Background
To assess central corneal thickness (CCT) and its associations in a Russian population.

Methods
The population-based Ural Eye and Medical Study included 5899 (80.5%) out of 7328 eligible individuals. As part of an ophthalmological and general examination, CCT was measured by Scheimflug imaging.

Results
The study included 5792 (98.2%) participants (age:58.8 ± 10.6 years;range: 40–94 years) with available bilateral CCT measurements. Mean CCT was larger in Russians than non-Russians (549.5 ± 32.8 µm versus 539.2 ± 33.9 µm; P < 0.001). In multivariable analysis, thicker CCT was associated (regression coefficient r:0.43) with younger age (standardized regression coefficient beta:−0.09; non-standardized regression coefficient B:−0.29;95% confidence interval (CI):−0.39,−0.20; P < 0.001), male sex (beta:0.05; B:3.10; 95%CI:1.18,5.03; P = 0.002), urban region of habitation (beta:0.10; B:6.83; 95%CI:4.61, 9.05; P < 0.001), Russian ethnicity (beta:0.04; B:3.48; 95%CI:1.04, 5.91; P = 0.005), higher level of education (beta:0.04; B:0.97;95%CI:0.29,1.66; P = 0.006), higher serum bilirubin concentration (beta:0.05;B:0.15; 95%CI:0.07,0.23;P < 0.001), lower corneal refractive power (beta:−0.09;B:11.92; 95%CI:−2.50,−1.35; P < 0.001), smaller anterior chamber angle (beta:−0.07;B:−0.38;95%CI:−0.52,−0.24;P < 0.001), higher IOP readings (beta:0.38; B:3.47; 95%CI:3.21,3.73; P < 0.001), and higher rise in IOP readings by medical mydriasis (beta:0.07; B:0.88;95%CI:0.54,1.22;P < 0.001). In that model, CCT was not associated with body height (P = 0.14), previous cataract surgery (P = 0.10), axial length (P = 0.18) or prevalence of glaucoma (P = 0.11). The mean inter-eye difference in CCT was 8.52 ± 13.9 µm (median:6.0;95CI:8.16,8.88). A higher inter-eye CCT difference was associated with older age (beta:0.08; B:0.11;95%CI:0.07,0.15; P = 0.01), lower level of education (beta:−0.04;B:−0.34; 95%CI:−0.60,−0.08; P < 0.001) and status after cataract surgery (beta:0.04; B:2.92;95%CI:1.02,4.83; P = 0.003).

Introduction conclusions
In this ethnically mixed population from Russia with an age of 40+ years, mean CCT (541.7 ± 33.7 µm) was associated with parameters such as younger age, male sex, Russian ethnicity, and higher educational level. These associations may be taken into account when the dependence of IOP readings on CCT are considered. Glaucoma prevalence was unrelated to CCT.

Published: March 2022

AbstractIntegrating ferroelectric negative capacitance (NC) into the field-effect transistor (FET) promises to break fundamental limits of power dissipation known as Boltzmann tyranny. However, realizing the stable static negative capacitance in the non-transient non-hysteretic regime remains a daunting task. The problem stems from the lack of understanding of how the fundamental origin of the NC due to the emergence of the domain state can be put in use for implementing the NC FET. Here we put forth an ingenious design for the ferroelectric domain-based field-effect transistor with the stable reversible static negative capacitance. Using dielectric coating of the ferroelectric capacitor enables the tunability of the negative capacitance improving tremendously the performance of the field-effect transistors.

Published: March 2022

AbstractMonolayers of layered materials, such as graphite and molybdenum dichalcogenides, have been the focus of materials science in the last decades. Here, we reveal benign stability and intriguing physical properties in the thinnest monolayer wurtzite (wz) semiconductors, which can be exfoliated from their bulk and stacked to reform the wz crystals. The candidate ZnX and CdX (X = S, Se, Te) monolayers possess low cleavage energy and direct bandgaps, which harbor strongly coupled ferroelectricity and ferroelasticity with low transition barriers, giant in-plane negative Poisson’s ratio, as well as giant Rashba spin splitting, enabling the co-tunability of spin splitting and auxetic magnitudes via multiferroic switching. These wz monolayers can be used as building blocks of devices structures, due to their inherent “self-healable” capacity, which offer more flexibility for semiconductor fabrication and provide a natural platform to probe the interplay of multiple physical effects, bringing light into the rich physics in tetrahedral semiconductors.
Cumulative burden of psychiatric disorders and self-harm across 26 adult cancers
Authors: Chang Wai Hoong , Lai Alvina G. 
Published: March 2022

AbstractCancer is a life-altering event causing considerable psychological distress. However, information on the total burden of psychiatric disorders across all common adult cancers and therapy exposures has remained scarce. Here, we estimated the risk of self-harm after incident psychiatric disorder diagnosis in patients with cancer and the risk of unnatural deaths after self-harm in 459,542 individuals. Depression was the most common psychiatric disorder in patients with cancer. Patients who received chemotherapy, radiotherapy and surgery had the highest cumulative burden of psychiatric disorders. Patients treated with alkylating agent chemotherapeutics had the highest burden of psychiatric disorders, whereas those treated with kinase inhibitors had the lowest burden. All mental illnesses were associated with an increased risk of subsequent self-harm, where the highest risk was observed within 12 months of the mental illness diagnosis. Patients who harmed themselves were 6.8 times more likely to die of unnatural causes of death compared with controls within 12 months of self-harm (hazard ratio (HR), 6.8; 95% confidence interval (CI), 4.3–10.7). The risk of unnatural death after 12 months was markedly lower (HR, 2.0; 95% CI, 1.5–2.7). We provide an extensive knowledge base to help inform collaborative cancer-psychiatric care initiatives by prioritizing patients who are most at risk.

Published: March 2022

AbstractIn the past decades, China has undergone dramatic land use/land cover (LULC) changes. Such changes are expected to continue and profoundly affect our environment. To navigate future uncertainties toward sustainability, increasing efforts have been invested in projecting China’s future LULC following the Shared Socioeconomic Pathways (SSPs) and/or Representative Concentration Pathways (RCPs). To supplements existing datasets with a high spatial resolution, comprehensive pathway coverage, and delicate account for urban land change, here we present a 1-km gridded LULC dataset for China under 24 comprehensive SSP-RCP scenarios covering 2020–2100 at 10-year intervals. Our approach is to integrate the Global Change Analysis Model (GCAM) and Future Land Use Simulation (FLUS) model. This dataset shows good performance compared to remotely sensed CCI-LC data and is generally spatio-temporally consistent with the Land Use Harmonization version-2 dataset. This new dataset (available at https://doi.org/10.6084/m9.figshare.14776128.v1) provides a valuable alternative for multi-scenario-based research with high spatial resolution, such as earth system modeling, ecosystem services, and carbon neutrality.
A Review of the Effect of Classroom Sound-Field Amplification on Children in Primary School
Authors: Mealings Kiri 
Published: March 2022

Purpose:
Being able to hear the teacher clearly is an important factor for children's learning. However, classrooms often have suboptimal listening conditions. Sound-field amplification systems (SFAS) can help improve classroom listening conditions by increasing the level of the teacher's speech compared to the background noise throughout the classroom. The aim of this review article was to review the effect of SFAS on children in primary school.

Method:

A comprehensive search of four online databases (ERIC, PubMed, Scopus, and Web of Science) was conducted. The search terms were
classroom sound-field amplification
and
classroom amplified distribution system.
Twenty-one articles were deemed relevant for the review plus an additional six from their references.

Results:
Most articles were published between 1996 and 2015. Only one article was published since 2016. A range of child populations were studied including typically developing children and children with difficulties and disabilities such as hearing loss, developmental language disorders, attention-deficit/hyperactivity disorder, emotional and behavior disorders, Down syndrome, and developmental disabilities. There were several different measures that were used to evaluate the effectiveness of SFAS including speech perception assessments, language assessments, academic and comprehension assessments, classroom observations, interviews, and questionnaires. Improvements with SFAS were found for speech perception, listening comprehension and auditory analysis, language outcomes, academic outcomes, and behavior.

Conclusion:
SFAS can benefit children's listening and learning; however, the child's background, classroom reverberation time (limit to < 1 s), and layout and type of learning activities, especially in modern classrooms, need to be taken into consideration.

Dans son introduction, Catherine Potel repart des origines de la psychomotricité qui, dès l’énoncé de son titre, met au centre de son objet d’étude toute la question de la complexité de l’humain. Elle insiste sur la première des mises en sens de ce « métier à tisser » - quasi artisanal » par la simplicité des médiations psychocorporelles proposées aux patients - celle d’une résistance au clivage corps psyché qui menace tous ceux qui souffrent, dans leur corps ou dans leur psyché. La globalité de l’être est l’ancrage même de la psychomotricité.

Published: March 2022

AbstractA convenient and practical method for the synthesis of unsymmetrical triarylmethanes was demonstrated through a one-pot three-component double Friedel–Crafts reaction of various aliphatic, aromatic, or heteroaromatic aldehydes with N,N-dialkylanilines and indoles by using a Brønsted acidic ionic liquid as the catalyst. This method was successfully applied under metal- and solvent-free conditions at 80 °C, affording the corresponding unsymmetrical triarylmethane products in moderate to high yields from a broad range of substrates. In addition, the mechanism of this reaction was studied by quantitative NMR analysis.

Published: March 2022

Single nucleotide polymorphisms (SNPs) are the most abundant form of genetic variation in eukaryote genomes and may be useful for selection of genetically distant parents for crossing in breeding programs. In this study, genome-wide SNPs of tall fescue (Festuca arundinacea Schreb.) were genotyped by using double-digest restriction-site-associated DNA sequencing to determine the genetic variation and differentiation among and within forage, turf and hybrid populations. After filtering, 16 036 SNPs were used to investigate genetic diversity and for structure analysis. SNP markers clearly differentiated the populations from each other. However, the hybrid population had a higher genetic similarity with the turf population than with the forage population. The results were confirmed by genetic differentiation (fixation index, Fst) and gene flow (Nm) statistics, so that low Fst and high Nm were observed between turf and hybrid groups, indicating less genetic distance and a high similarity between them. Based on the results of the weighted pair group method with arithmetic mean clustering, discriminant analysis of principal components and analysis of molecular variance, greater genetic differentiations were found among diverse turf, forage and hybrid populations, especially between turf and forage ones. In conclusion, numerous informative SNPs, natural allelic diversity-led domestication patterns, basic genetic variation statistics (e.g. Fst and heterozygosity) and population structures have multidimensional applicability for tall fescue genomics-assisted breeding.
Dynamic gene expression and growth underlie cell-to-cell heterogeneity in
Escherichia coli
stress response
Authors: Sampaio Nadia M. V. , Blassick Caroline M. , Andreani Virgile , Lugagne Jean-Baptiste , Dunlop Mary J. 
Published: March 2022

Significance
Individual bacteria that share identical genomes and growth environments can display substantial cell-to-cell differences in expression of stress-response genes and single-cell growth rates. This phenotypic heterogeneity can impact the survival of single cells facing sudden stress. However, the windows of time that cells spend in vulnerable or tolerant states are often unknown. We quantify the temporal expression of a suite of stress-response reporters, while simultaneously monitoring growth. We observe pulsatile expression across genes with a range of stress-response functions, finding that single-cell growth rates are often anticorrelated with reporter levels. These dynamic phenotypic differences have a concrete link to function, in which individual cells undergoing a pulse of elevated expression and slow growth are predisposed to survive antibiotic exposure.

Published: March 2022

Significance
Agricultural systems are already major forces of ammonia pollution and environmental degradation. How agricultural ammonia emissions affect the spatio-temporal patterns of nitrogen deposition and where to target future mitigation efforts, remains poorly understood. We develop a substantially complete and coherent agricultural ammonia emissions dataset in nearly recent four decades, and evaluate the relative role of reduced nitrogen in total nitrogen deposition in a spatially explicit way. Global reduced nitrogen deposition has grown rapidly, and will occupy a greater dominant position in total nitrogen deposition without future ammonia regulations. Recognition of agricultural ammonia emissions on nitrogen deposition is critical to formulate effective policies to address ammonia related environmental challenges and protect ecosystems from excessive nitrogen inputs.
Pedagogical devices
Authors: Sterk Darryl 
Published: March 2022

AbstractThe “partial translation” of Inuktitut-language lyrics in the Indigenous filmAtanarjuat: The Fast Runner(directed by Zacharias Kunuk, 2001) has been interpreted as a means of challenging outsiders to understand the film “emically,” meaning from insiders’ perspectives. On this interpretation,Atanarjuatis linguistically exclusionary, because the challenge of partial translation effectively excludes most outsiders from a full understanding. But given the problem of language shift in Indigenous communities, we should not expect Indigenous films to be linguistically exclusionary in general, or they would exclude young Indigenous insiders along with outsiders. We should instead expect Indigenous films to adopt an inclusionary approach to subtitling, consistent with projects of language revitalization. To see what form such an approach might take, I analyzed three Indigenous films from Taiwan in which speech in Atayalic languages is subtitled in Mandarin. Staggered over three-and-a-half decades, these three films index the subtitling approach as a function of concern about language shift. I found that all three films were fully, not partially translated, but that the two films made in a context of concern about language shift were subtitled pedagogically. The two pedagogically subtitled films are “devices” for the pedagogy of Atayal, the most widely spoken Atayalic language. This result from Taiwan suggests that a pedagogical approach might be common in the subtitling of Indigenous films in settler societies around the world.
Theoretical investigation on un-doped and doped TiO2 for solar cell application

Published: March 2022

Abstract
Enhancing solar cell efficiency is one of the most challenging and demanding topics for PV researchers. An ab initio study is done here on the structure of crystal, formation energies, electronic structure, the density of states, effective mass, and optical properties of pure and S-doped, Fe-doped, and Fe-/S-doped anatase TiO2. Co-doping causes a significant reduction in the bandgap, suppresses the charge carrier’s recombination rate, and shifted absorption spectra from UV to the visible region. Hence, co-doped anatase TiO2 with Fe and S is more favorable as a buffer layer of the solar cell compared to S-doped and Fe-doped TiO2. The forecasted values of all quantities will benefit researchers to examine these materials for further photovoltaic applications.

Abstract
In this research, a silver/K-carrageenan nanocomposite was synthesized using a chemical reduction method assisted by microwave irradiation using NaOH as an accelerator. The aims of this research is to determine the optimum conditions for the preparation of silver nanoparticles with NaOH variations, microwave irradiation time and, AgNO3 concentration. AgNO3 compounds function as precursors and K-carrageenan as a reducing agent, stabilizer and also a matrix in silver-K-Carrageenan nanocomposites. The formation of silver nanoparticles was identified using a UV-Vis spectrophotometer which is associated with the LSPR phenomenon. Testing of antibacterial activity using the diffusion method against S.Aureus bacteria. The results showed that the silver nanoparticles formed on the silver/K-Carrageenan nanocomposite were characterized by the appearance of an absorption band in the 400 nm region. NaOH concentration, irradiation time and AgNO3 concentration affect the absorbance value at the maximum absorption, which indicates the effect on the amount of silver nanoparticles. The optimal condition for the synthesis of silver nanoparticles is the use of NaOH 0,014 M with an irradiation time of 6 minutes. The concentration of AgNO3 precursor is directly proportional to the amount of silver nanoparticles formed in the nanocomposite. Silver/K-Carrageenan nanocomposite has high antibacterial activity and potential as antibacterial material.

AbstractThe study of preparation and characterization of microcrystalline cellulose from the Lembang / narrowleaf cattail(Typha angustifoliaL.) has been carried out. Alkalinization was done to remove lignin and hemicellulose compounds. The bleaching process was done by adding 4 M HCl at 65 oC for 3 hours and then sonicated for 10 minutes. The cellulose yield obtained was 32.2%. The Fourier Transform Infrared (FTIR) spectra indicated the appearance of some specific functional groups (O-H, -C-H, =C-H and C-O, and C-O-C). Scanning Electron Microscope (SEM) showed that the structure of cellulose is a long crystalline with a diameter of 3.1 µm. Thermogravimetric analysis (TGA) showed decomposition at higher temperatures of 349.13, 366.66 and 353.24 oC for cellulose after hydrolysis, cellulose before hydrolysis, and TaL powder. Crystalline index and crystalline size of microcrystalline cellulose analyzed by X-Ray Diffraction (XRD) were 71.1% and 2.4 nm, respectively.

Published: March 2022

Abstract
Various chemical substances have been used as pharmaceutical active ingredients, such as ibuprofen, which is an analgesic. The validity of an analytical method of a pharmaceutical active ingredient combined with co-formers into one single phase should be confirmed so that the analysis can be well received. Therefore, this study aims to validate the analytical method of ibuprofen in multicomponent crystals using a UV spectrophotometer with the parameters of linearity, accuracy, precision, and placebo interference. Ibuprofen was dissolved in phosphate buffer with a pH of 7.2 using ethanol as co-solvent. The solution was diluted and analyzed to obtain the maximum wavelength. The calibration curve was analyzed to obtain the linear regression equation for ibuprofen to determine linearity. The accuracy and precision parameters were measured by the results of replications. Meanwhile, placebo interference was determined using an equimolar ratio of 1:1 between ibuprofen with malic acid and tartaric acid. The results of the analysis showed that ibuprofen had a maximum wavelength of 265 nm. The linearity, accuracy, precision, and placebo interference fulfilled the requirement. Based on the validation parameter performed, the analytical method used was valid for the analysis of ibuprofen multicomponent crystals with malic acid and tartaric acid as co-formers.
