Authors: Rantakokko Satu 
Published: July 2023

<p>The TIER model is a designer tool for designing technical instructions for extended reality (XR) environments. This article reports a pilot study towards validating the model with user preconceptions towards XR-based technical instructions. Understanding preconceptions is important in user-centered design. The pilot test entails the presentation of instructions for a LEGO construction task via video and VR. The results indicate interest and willingness to test XR-based solution, but reluctance for regular use. The TIER model showed how the model supported the process of recognizing preconceptions and operated as a tool for an organized design process of XR-based technical instructions. </p>
The influence of bilingualism on gray matter volume in the course of aging: a longitudinal study

Published: July 2023

BackgroundBilingualism is associated with higher gray matter volume (GMV) as a form of brain reserve in brain regions such as the inferior frontal gyrus (IFG) and the inferior parietal lobule (IPL). A recent cross-sectional study reported the age-related GMV decline in the left IFG and IPL to be steeper for bilinguals than for monolinguals. The present study aimed at supporting this finding for the first time with longitudinal data.MethodsIn the current study, 200 participants aged 19 to 79 years (87 monolinguals, 113 sequential bilinguals, mostly native German speakers with variable second language background) were included. Trajectories of GMV decline in the bilateral IFG and IPL were analyzed in mono- and bilinguals over two time points (mean time interval: 3.6 years). For four regions of interest (left/right IFG and left/right IPL), mixed Analyses of Covariance were conducted to assess (i) GMV changes over time, (ii) GMV differences for language groups (monolinguals/bilinguals), and (iii) the interaction between time point and language group. Corresponding analyses were conducted for the two factors of GMV, surface area (SA) and cortical thickness (CT).ResultsThere was higher GMV in bilinguals compared to monolinguals in the IPL, but not IFG. While the left and right IFG and the right IPL displayed a similar GMV change in mono- and bilinguals, GMV decline within the left IPL was significantly steeper in bilinguals. There was greater SA in bilinguals in the bilateral IPL and a steeper CT decline in bilinguals within in the left IPL.ConclusionThe cross-sectional observations of a steeper GMV decline in bilinguals could be confirmed for the left IPL. Additionally, the higher GMV in bilinguals in the bilateral IPL may indicate that bilingualism contributes to brain reserve especially in posterior brain regions. SA appeared to contribute to bilinguals’ higher GMV in the bilateral IPL, while CT seemed to account for the steeper structural decline in bilinguals in the left IPL. The present findings demonstrate the importance of time as an additional factor when assessing the neuroprotective effects of bilingualism on structural features of the human brain.

A qualitative study of the experiences of nurses working in general practice during the COVID-19 pandemic: implications for future practice
Authors: Anderson Helen , Adamson Joy 
Published: July 2023

BackgroundGeneral practice experienced significant challenges throughout the COVID-19 pandemic. There has been little exploration of the experiences of nurses working in general practice and the impact on care delivery, job satisfaction, workload, stress and professional support. Understanding these experiences can inform future practice.AimTo explore how nurses working in general practices in England experienced delivering care during the COVID-19 pandemic and to evaluate the impact of working practices on professional wellbeing.MethodQualitative design incorporating three case study sites in the north of England plus semi-structured interviews with nurses working in general practice across England and national nurse leaders (participantsn= 40). The study was funded by the General Nursing Council Trust.ResultsFive interconnected themes were generated: 1) the challenge of change; 2) the space to nurse; 3) professional identity, value, and visibility; 4) layers of wellbeing, stress, and burnout; and 5) challenges and opportunities for retention. The pandemic exacerbated many challenges for nurses working in general practice. To address their needs post pandemic, key factors include: nurse involvement in key decision-making at senior levels; recognition of value of nurses working in general practice; equal access to opportunities to work differently; strategic attention to recruitment and retention; action from employers and professional associations to support nurses’ wellbeing; and adaptation of HEI teaching to reflect new and hybrid ways of working.ConclusionThe pandemic has laid bare challenges faced by nurses in general practice. Nurses require specific support to maintain professional wellbeing and to aid retention.

Se analizaron las concentraciones diarias de material particulado en el aire (PM) en la azotea de la Rectoría de la Universidad de Panamá, con una aspiradora ubicada a 90 metros sobre el nivel del mar. Se recolectaron y analizaron muestras diarias desde enero de 2006 hasta diciembre de 2022, sumando un total de 6 209 datos. La curva de la concentración del material particulado (PM) versus el día del año es indicativa de una alta contaminación atmosférica diaria por partículas en suspensión. La concentración diaria de PM, influenciada por factores meteorológicos, sugiere una clasificación en cuatro etapas anuales con comportamiento estacional, aunque con variabilidad significativa. Estas etapas son, la estación seca con comportamiento alotrópico, la de transición con decrecimiento diario lineal, dos etapas lluviosas una moderada y la otra intensa, las cuales, juntas poseen una variación senoidal. Se encontró una alta correlación inversa de PM con la Humedad Relativa y con la precipitación y una correlación directa alta con la temperatura y la rapidez del viento y ningún tipo de correlación con la presión y la dirección del viento. Esas altas correlaciones entre PM y la meteorología son indicadoras que las PM contribuyen al cambio climático.

Published: July 2023

Recent advances include understanding bone fragility's genetic and molecular basis and discovering acquired causes of pediatric osteoporosis. Genetic pediatric bone defects are common and morbid, causing osteoporosis. Due to the rising prevalence of chronic diseases like Duchenne muscular dystrophy and immobility, as well as the use of drugs like steroids that can damage bones, secondary osteoporosis in children is rising. Early detection of osteoporosis in children is essential for diagnosis and treatment. Dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) scan for bone densitometry and vertebral fractures in pediatric osteoporosis patients. Pediatric osteoporosis requires a comprehensive team of bone disease specialists. A specialist should prevent and cure fragility fractures and improve patients' quality of life. Bisphosphonates, the most often recommended drugs for children, enhance BMD and restructure spinal fractures when given promptly. Raising awareness of osteoporosis risk factors, screening youngsters, and referring them to a specialist can detect silent fractures early and avoid bone degeneration. This article reviews childhood osteoporosis and its epidemiology. The global sickness classification and study program are briefly explained.

Published: July 2023

AbstractChiral plasmonics has been actively pursued since pushing its light‐matter interaction to an unnaturally extreme regime. Recently, chirality‐encoded metal–insulator–metal (MIM) motifs have promised compelling advantages in advancing chiroptic responses, as they enable a capacitive coupling and its resultant strong electric and magnetic resonances. However, the deterministic control over chiral MIM working at the visible regime is out of reach. Here, large‐area MIM resonators are demonstrated using non‐lithographically assembled chiral gold nanoparticles (helicoids) and subsequent gold layer deposition, and their boosted chiroptical responses at the visible regime are proven. The thickness of the topcoat Au and the dielectric gap can precisely tune the strength of capacitive coupling. The numerical analyses support that the optimally tuned capacitive coupling in the chiral MIM structure not only strengthens both electric and magnetic dipolar resonances but also makes their spectral positions closer to each other.

Published: July 2023

AbstractHigh entropy alloys (HEAs) are composed of five or more metal elements with similar proportions. Due to the electronic structure among metal elements, they have abundant active sites and have good catalytic activity and stability as materials. Therefore, they have great promise in electrochemical energy storage and electrocatalysis. This paper reviews the preparation and characterization methods of HEAs, and the applications of HEAs in catalysis, especially the contribution in lithium‐sulfur batteries, but also in Electrolyzed water and other energy storage materials. The challenges of HEAs in catalysis and their future developments are also presented.
Design of HDPE‐based nanocomposite with excellent thermal‐oxidative aging resistance, mechanical properties and electrical insulation properties: Dispersing nano‐ZnO assisted by natural rubber latex
Authors: Li Jinglin , Mou Wenjie , Zhu Jinxin , Hu Chaoqiang 
Published: July 2023

AbstractModification with nanoparticles is an effective way of overcoming the inherent defects of high‐density polyethylene (HDPE). However, the uniform dispersion of nanoparticles in the polymer matrix is the key point of this method. Here, natural rubber latex (NRL) was used for the auxiliary dispersion of self‐made nano zinc oxide (nano‐ZnO) to realize the uniform dispersion of nano‐ZnO in HDPE. The HDPE‐based nanocomposite with excellent thermo‐oxidative aging resistance, mechanical properties and electrical insulation properties were successfully prepared. Three weight percent of nano‐ZnO was uniformly dispersed in HDPE (HLZ3), which not only synergistically toughened HDPE with natural rubber (coagulated natural rubber latex, NR), but also maintained the tensile strength of the matrix. Moreover, the interfacial interactions between nanoparticles and polymers improved the alternating current (AC) breakdown strength and volume resistivity of the HDPE matrix. After aging treatment, the crystallinity of HLZ3 decreased very little, and its carbonyl index was much smaller than that of pure HDPE. Therefore, it has the best performance retention rate. This nanoparticle dispersion method has certain reference significance. And this HDPE‐based nanocomposite material is expected to be used in the outer sheath of cables.
Multiple suppressing small interfering RNA for cancer treatment—Application to triple‐negative breast cancer

Published: July 2023

AbstractCertain cancers, such as triple‐negative breast cancer (TNBC), pose a challenging prognosis due to the absence of identifiable hormone‐related receptors and effective targeted therapies. Consequently, novel therapeutics are required for these cancers, offering minimal side effects and reduced drug resistance. Unexpectedly, siRNA‐7, initially employed as a control, exhibited significant efficacy in inhibiting cell viability in MDA‐MB‐231 cells. Through a genome‐wide search of seed sequences, the targets of siRNA‐7 were identified as cancer‐related genes, namely PRKCE, RBPJ, ZNF737, and CDC7 in MDA‐MB‐231 cells. The mRNA repression analysis confirmed the simultaneous suppression by siRNA‐7. Combinatorial administration of single‐targeting siRNAs demonstrated a comparable reduction in viability to that achieved by siRNA‐7. Importantly, siRNA‐7 selectively inhibited cell viability in MDA‐MB‐231 cells, while normal HDF‐n cells remained unaffected. Furthermore, in a xenograft mouse model, siRNA‐7 exhibited a remarkable 76% reduction in tumor volume without any loss in body weight. These findings position siRNA‐7 as a promising candidate for a novel, safe, specific, and potent TNBC cancer therapeutic. Moreover, the strategy of multiple suppressing small interfering RNA holds potential for the treatment of various diseases associated with gene overexpression.

AbstractObjectivesAortic stenosis (AS) is characterized by obstruction of blood outflow from the left ventricle, which can impair target organ perfusion such as the brain. We hypothesized that hemodynamic changes in AS may lead to dysfunction of cerebral blood flow regulatory mechanisms. The aim of our study was to evaluate neurovascular coupling in patients with AS by Transcranial Doppler ultrasonography.MethodsNeurovascular coupling was assessed using visually evoked cerebral blood flow velocity responses (VEFR) calculated as relative blood flow velocity changes in the posterior cerebral artery upon visual stimulation. We analyzed peak systolic, mean and end diastolic VEFR in 54 patients with severe AS and 43 controls in 10 consecutive cycles of visual stimulation. Repeated‐measures ANOVA test was used to compare cerebral hemodynamic data by group.ResultsPatients with AS had significantly higher peak systolic (12.9% ± 5.6% and 10.5% ± 4.5%; p = .009) and mean VEFR (14.4% ± 5.8% and 12.2% ± 4.9%; p = .021) compared to controls, whereas only a tendency for higher end diastolic VEFR was observed (16.7% ± 6.9% and 14.4% ± 6.2%; p = .061).ConclusionWe have shown for the first time that patients with severe AS exhibit higher VEFR than controls indicating dysregulation of neurovascular coupling, which can be one of the factors contributing to development of cognitive decline.

Published: July 2023

AbstractThe reason of this study is to synthesize ZrB2 nano powder utilizing boric acid and phenolic resin. Within the study of zirconia as a source of zirconium, boric acid was used as a source of boron and phenolic resin as a carbon source. The theoretical and experimental studies of ZrB2 were synthesized by boro/carbothermal diminishment from the novel sol–gel technology. The zirconia powder was crushed for 8 h and in conjunction with different molar proportions of boric acid, in this consider, a kinetic demonstrate for reactions creating ZrB2 was built up based on thermodynamic analysis. The resultant powder was synthesized in a neutral atmosphere controlled in 1450°C and 1550°C. After it was also observed that, with the increase of molar proportion of H3BO3, the reaction delivered ZrB2 powders in high amount of the boron reaction. The compound was analyzed by an X‐ray diffraction technique and found to be ZrB2 powder that was synthesized with the purity of approximately 98%.

AbstractIn this paper, we present a probabilistic study of rare phenomena of the cubic nonlinear Schrödinger equation on the torus in a weakly nonlinear setting. This equation has been used as a model to numerically study the formation of rogue waves in deep sea. Our results are twofold: first, we introduce a notion of criticality and prove a Large Deviations Principle (LDP) for the subcritical and critical cases. Second, we study the most likely initial conditions that lead to the formation of a rogue wave, from a theoretical and numerical point of view. Finally, we propose several open questions for future research.
Effect of Fluoride Atoms on the Electrochemical Performance of Tetracyanoquinodimethane(TCNQ) Electrodes in Zinc‐ion Batteries

Published: July 2023

AbstractTetracyanoquinodimethane (TCNQ) electrode material has achieved excellent performance in aqueous zinc‐ion batteries (AZIBs). However, fundamental understanding about effect of substitutes on electrochemical performance of TCNQ remain unknown. In this work, the effects of fluorine (F) as an electron‐absorbing group on the structure, morphology and electrochemical performance of TCNQ and storage mechanism of TCNQ in AZIBs are discussed. Theoretical calculation proves that the introduction of fluorine atoms decreases lowest unoccupied molecular orbital (LUMO) energy of TCNQ thus affect the redox potential. Electrochemical performance of TCNQ/Fluoro‐7,7,8,8‐tetracyanoquinodimethane (FTCNQ)/2,3,5,6‐Tetrafluoro‐7,7,8,8‐tetracyanoquinodimethane (F4TCNQ) is evaluated from 25 °C to −20 °C in AZIBs. Results tend out that with the increasing substituents of F on TCNQ molecular, their stability in AZIBs decrease. Dipole moment calculation further shows that the introduction of fluorine atoms is inconducive to the stability of the electrode material in aqueous solution. Ex‐situ characterization demonstrate that electron withdrawing groups do not change the REDOX center of TCNQ electrode materials. Our work provides a new thought for the selection of the electrode material in AZIBs.
