Abstract
Beauty and youth are the most critical and challenging issues in medicine and beauty science, and humans always seek to find a new method for the elixir of youth. Innovative technologies based on physical principles have also been presented in recent years. In the meantime, cold plasma technology, which previously showed exciting results in the skin, is currently being investigated due to its remarkable ability to treat diseases and skin care. This study used the FEDBD plasma device for skin rejuvenation in animal samples. There were two groups of six male Wistar rats. One group was treated with plasma with a power of 3.3 W, and the second group was considered the control group for a better comparison. Plasma processing was done on the back of the neck of mice with an area of 18 square centimeters. So far, complete quantitative measurement has not been done, and few studies have been done. Before starting the treatment, immediately after the treatment, the fourth week, and the tenth week of follow-up, biometric tests were performed, including moisture level, evaporation from the skin surface, erythema and melanin, skin elasticity and firmness with an MPA9 device and cutometer. The thickness and density of the epidermis and dermis, an essential indicator in rejuvenation, were evaluated with a skin ultrasound device. Also, the level of oxygen, perfusion, and interstitial water (edema) was checked using a Tivita tissue hyperspectral camera at a depth of 6 mm of the skin. Active species produced by plasma, plasma temperature, and device power were investigated and recorded using physical tests.

Abstract
Technological advances in smartphones, tablets, computer games, virtual reality, metaverse, and other fields have made gaze estimation (GE) using standard hardware more necessary than ever before. It can also be used in other areas such as psychology, increased driving safety, and advertisement. This paper proposes a structure based on convolutional neural networks (CNNs). In this structure, several well-known CNNs are implemented and trained with a section of the GazeCapture dataset for acceleration. The SE-ResNext network, which has the best results in initial training, is selected in the end. The test error for the designated structure is 1.32 cm in training with the entire dataset. The ambient light is an effective factor in GE accuracy. It clearly affects different GE methods. The dataset is divided into low-light and bright-light environment sets to find a solution. The bright-light environment samples are much more abundant than the low-light ones, something which causes a bias in gaze estimator training. Therefore, standard data augmentation methods are employed to increase the number of low-light samples and retrain the gaze estimator. As a result, the GE error is reduced from 1.20 to 1.06 cm for bright-light environments and from 3.39 to 1.87 cm for low-light environments. To examine resistance of the gaze estimator to head movement, the test dataset is manually and intuitively classified into five subsets based on head positions. In this classification, test errors of 1.27, 1.427, 1.496, 1.952, and 2.466 cm are respectively obtained for the frontal, roll to right, roll to left, yaw to right, and yaw to left head positions.

Published: March 2023

Abstract
Breast cancer is one of the most common causes of death in women worldwide; however, early detection could mitigate theassociated number of deaths, where new screening techniques applicable to the entire risk population are the key to achievingthis goal. By identifying the risk population, it is easier to plan cancer prevention programs and contribute to reducing thenumber of deaths from breast cancer; however, despite new promising technologies for early cancer detection, there arefew proposals available to achieve massively applicable techniques to screen the entire breast cancer risk population. Wepresent a proof-of-concept for screening breast cancer using a noninvasive and potentially low-cost technique that detects thecancerization field effect by spectral analysis (FEDSA) using near-infrared backscattered light. To test the concept of FEDSA todetect cancer, we performed FEDSA measurements in 24 women divided into two groups, the first group of 17 normal womenand the second group of seven women with previously detected abnormalities in the breast; we identified significant differencesin the FEDSA spectra of both groups, suggesting the potential of FEDSA as a promising screening technique for the earlydetection of breast cancer.

Abstract
Background
Hepatocellular carcinoma (HCC) is one of the highly malignant and aggressive gastrointestinal tumors. Anoikis is a specific form of cell death that is closely related to malignant aggressive behavior of tumors. The role and significance of anoikis-related genes (ANRGs) in HCC deserve to be explored.
Methods
Here, transcriptome profiling and relevant clinical data needed for analysis were collected from public databases. Prognostic model of ANRGs was constructed by using Lasso regression algorithm. Then, patients were given a reasonable risk grouping, and survival analysis was conducted to compare the different survival rates in each risk group. Receiver operating characteristic (ROC) curve was employed to examine the predictive accuracy of the prognostic model. The single sample gene set enrichment (ssGSEA) was carried out to investigate important disease characteristics of each risk group, such as immune status profile and tumor microenvironment differences. The gene set enrichment analysis (GSEA) method was also implemented to complete functional and pathway enrichment analysis. In addition, drug sensitivity analysis and exploration of single cell data for HCC were completed with the aid of online analytical databases.
Results
We successfully created a prognostic model containing 14 ANRGs, namely: ANXA5, BSG, SKP2, BAK1, PHLDA2, CDKN3, SFN, EZH2, HMGA1, PBK, NRAS, SLC2A1, MAD2L1 and CASP2, and observed a lower overall survival in high-risk group. The ROC curve confirmed good performance of this new model in predicting prognosis. The ssGSEA revealed significant differences in tumor immune microenvironment between different risk groups, with higher activity about cancer related pathways in high-risk group. The expression level of immune checkpoint and m6A genes also differed between risk subgroups. These prognostic genes were also be related to chemotherapy susceptibility.
Conclusion
The novel prognostic model identified with ANRGs can be applied to prediction prognostic and assessment immune status profile, tumor microenvironment differences and chemosensitivity in HCC. Rational use of the prognostic new model may provide an important reference for individualized treatment of HCC.

Published: March 2023

Abstract
Reconfigurable plasmonic-photonic electromagnetic devices have been incessantly investigated for their great ability to optically modulate through external stimuli to meet today's emerging needs, with chalcogenide phase-change materials being promising candidates due to their remarkably unique electrical and optics, enabling new perspectives in recent photonic applications. In this work, we propose a reconfigurable resonator using planar layers of stacked ultrathin films based on Metal-dielectric-PCM, which we designed and analyzed numerically by the Finite Element Method (FEM). The structure is based on thin films of Gold (Au), aluminum oxide (Al2O3), and PCM (In3SbTe2) used as substrate. The modulation between the PCM phases (amorphous and crystalline) allows the alternation from the filter to the absorber structure in the infrared (IR) spectrum (1000-2500 nm), with an efficiency greater than 70% in both cases. The influence of the thickness of the material is also analyzed to verify tolerances for manufacturing errors and dynamically control the efficiency of transmittance and absorptance peaks. The physical mechanisms of field coupling and transmitted/absorbed power density are investigated. We also analyzed the effects on polarization angles for Transversal Electric (TE) and Transversal Magnetic (TM) polarized waves for both cases.

Abstract
Climate warming leads to frequent extreme precipitation events, which is a prominent manifestation of the variation of the global water cycle. Using data of 1842 meteorological stations in the Huang-Huai-Hai-Yangtze River Basin and 7 climate models of CMIP6,the historical and future precipitation data were obtained using the Anusplin interpolation, BMA method, and a non-stationary deviation correction technique. The temporal and spatial variations of extreme precipitation in the four basins from 1960 to 2100 were analyzed. The correlation between extreme precipitation indices and their relationship with geographical factors was analyzed. The results show that: (1) in the historical period, CDD and R99pTOT showed an upward trend, with growth rates of 14.14% and 4.78%, respectively. PRCPTOT showed a downward trend, with a decreasing rate of 9.72%. Other indices showed minimal change. (2) Based on SSP1-2.6, the intensity, frequency, and duration of extreme precipitation changed by approximately 5% at SSP3-7.0 and 10% at SSP5-8.5. The sensitivity to climate change was the highest in spring and autumn. The drought risk decreased and the flood risk increased in spring. The drought risk increased in autumn and winter, and the flood risk increased in the alpine climate area of the plateau in summer. (3) CDD, CWD, R95pD, R99pD, and PRCPTOT are affected by latitude. RX1day and RX5day are affected by longitude, and other indices are affected by longitude and latitude. The extreme precipitation index is significantly correlated with geographical factors, and areas above 3000 m above sea level are more sensitive to climate change.
The effect of visual rivalry in peripheral head-mounted displays on mobility
Authors: Han Shui'er , Kim Sujin , Jung Jae-Hyun 
Published: March 2023

Abstract
Recent head-mounted displays and smart glasses use vision multiplexing, an optical approach where two or more views are superimposed on each other. In vision multiplexing, augmented information is presented over an observer’s natural field of view, providing field expansion and critical information during mobility situations like walking and driving. Yet despite its utility, vision multiplexing may produce visual rivalry, a phenomenon where perception alternates between the augmented information and the background scene for seconds at a time. To investigate, we compared the effect of different peripheral vision multiplexing configurations (unilateral opaque, unilateral see-through and bilateral see-through) on the detection of augmented information, incorporating at the same time real-world characteristics (target eccentricity, depth condition, and gaze movement) for a more realistic assessment. Results showed a persistently lower target detection rate in unilateral configurations than the bilateral configuration, suggesting a larger effect of binocular rivalry on target visibility. Nevertheless, this effect does become attenuated when more naturalistic elements are incorporated, and we discuss recommendations for vision multiplexing design and possible avenues for further research.

Abstract
Fundamental motor skills (FMS) are essential for enjoyable, confident and skillful participation in physical activity across the lifespan. Due to the alarming low level of FMS proficiency in children and adolescents worldwide, the development of motor competency is an urgent issue for physical education. The promotion and implementation of a systematic process of teaching and learning FMS should be a physical education priority. Accordingly, effective assessment tools for evaluating FMS should be adopted or developed. Because FMS assessment for both children and adolescents need further effective solutions, we proposed the Fundamental Motor Skill in Sport test (FUS) to assess FMS proficiency in students across primary and secondary education. The FUS test involves six sport skill-based tasks: hurdling, jumping rope, forward roll, ball bouncing, throwing and catching a ball, and kicking and stopping a ball. This selection of skills represents high transferability to a wide range of sports and life activities. The results of our study provide evidence that the FUS test is valid, reliable, and feasible to administer in school settings. Therefore, this tool test has the potential to support deliberate practice and improve motor competency by providing a standardized and structured approach to measuring FMS among school-aged students.
Decrease in maximum paced walking speed may predict hospitalization in community-dwelling older people with disabilities: Assessment of change over time is more useful than a single time point assessment
Authors: Hirai Tomoya , Kamide Naoto , Shigeta Kyo 
Published: March 2023

Abstract
Purpose

Walking speed is a useful predictor of hospitalization for community-dwelling older people. However, whether it is an effective predictor for disabled community-dwelling older people has not been clarified. This study aimed to investigate the association of walking speed with unexpected hospitalizations in community-dwelling older people with disabilities.

Methods

The participants were ambulatory, community-dwelling, older adults aged 65 years or older with disability. Comfortable and maximum walking speeds were measured at two time points, baseline and 3 months later. Furthermore, the change over time at 3 months in walking speed was also calculated. If the change in walking speed decreased more than 0.1 m/s, it was defined as walking speed decreased. The primary outcome was unexpected hospitalization during 4-year follow-up. The associations among baseline walking speed, walking speed decline, and hospitalization were analyzed using Cox regression analysis adjusted for potential confounding factors.

Results

Ninety-three people were included, and unexpected hospitalization occurred in 47 people during 4-year follow-up. On Cox regression analysis adjusted for potential confounding factors, only the maximum walking speed decrease was significantly associated with hospitalization (Hazard ratio = 2.53, 95% confidence interval: 1.23–5.21], but not baseline walking speed and comfortable walking speed decrease.

Conclusion

As for the assessment of walking speed for prediction of unexpected hospitalization in disabled older people, measurement at a single time point is not useful, whereas change over time is. Monitoring of change over time in maximum walking speed appears to be one of the indicators for the health management of disabled older people.

Abstract
It is of great practical significance to carry out quantitative risk assessment of landslide disaster to protect people 's lives and property safety and maintain the sustainable development of social economy. The delineation of landslide disaster range is the key link of landslide risk evaluation in open-pit mine. This study took the open-pit mine in a block of Tar coalfield in Pakistan as the research background, and constructed a framework for landslide risk evaluation in open-pit mines. Based on the numerical simulation method of large deformation of landslide, the disaster range of landslide in open-pit mine was delineated. The stability of stope slope was analyzed based on rigid body limit equilibrium method. The probability of landslide instability was calculated based on Monte Carlo method. And the comprehensive fuzzy evaluation model was established to calculate the total risk value of landslide. The results showed that : through numerical simulation and empirical formula calculation, the landslide disaster range was accurately delineated, and the comprehensive vulnerability of the disaster bearing body was determined to be medium vulnerability ; the annual probability of landslide instability under natural conditions was 0.003, which belongs to moderate risk. The annual probability of landslide instability under rainstorm conditions was 0.024, which was highly dangerous ; the annual probability of landslide instability under seismic conditions was 0.018, which was highly dangerous. Under natural conditions, the total risk value of landslide was 114686.4 rmb, and the annual mortality rate of population was 0.0255 people / year. The total risk value of landslide under rainstorm condition was 11707570 rmb, and the annual mortality rate of population was 0.18375 people / year. The total risk value of landslide under earthquake condition was 43007400 rmb, and the annual mortality rate of population was 0.135 person / year, which was an unacceptable risk. The economic loss was a small geological disaster risk under natural conditions, and it was a medium-sized geological disaster risk under both rainstorm and earthquake conditions. Therefore, landslide prevention and control and management measures such as slope deformation monitoring were proposed to ensure the safety of personnel and property in open-pit mines.

Abstract
Background Alzheimer's disease (AD) is the leading cause of dementia, yet its underlying causes remain unknown. Increasing evidence supports a role for epigenetic modifications in AD pathogenesis. N6-methyladenosine (m6A), the most common RNA modification, is critical for learning and memory, and its abnormal presence has been observed in the brains of AD patients and animal models.
Methods To compare levels of m6A in RNA as well as expression of the responsible enzymes in peripheral blood mononuclear cells (PBMCs) between AD patients and healthy controls. 42 AD patients and 42 age-matched healthy controls were prospectively enrolled from the Affiliated Hospital of Jining Medical University. m6A levels in RNA were quantified and expressions of m6A-related proteins and mRNA were examined. Genome-wide profiling of m6A-tagged transcripts was performed by m6A-modified RNA immunoprecipitation sequencing and RNA sequencing.
Results Lower levels of m6A in PBMCs RNA in AD patients compared to controls, as well as downregulation of m6A methyltransferase and demethylase components. Dysregulation of m6A was associated with upregulation of m6A at 230 loci and downregulation at 163 loci, resulting in altered expression of disease-related genes.
Conclusion Dysregulation of m6A in RNA may play a role in AD pathogenesis and may provide new avenues for diagnosis and treatment.
