Optoelectronic tweezer(OET) is a useful optical micromanipulation technology that has been demonstrated for various applications in electrical engineering and most notably cell selection for biomedical engineering. In this work, we studied the use of light patterns with different shapes and thicknesses to manipulate dielectric microparticles with OET. It was demonstrated that the maximum velocities of the microparticles increase to a peak and then gradually decrease as the light pattern’s thickness increases. Numerical simulations were run to clarify the underlying physical mechanisms, and it was found that the observed phenomenon is due to the co-influence of horizontal and vertical dielectrophoresis forces related to the light pattern’s thickness. Further experiments were run on light patterns with different shapes and objects with different sizes and structures. The experimental results indicate that the physical mechanism elucidated in this research is an important one that applies to different light pattern shapes and different objects, which is useful for enabling users to optimize OET settings for future micromanipulation applications.

The greatest risk factor for neurodegeneration is *** genetics at birth only contributes 20-25%to the determinants of lifespan,so we actually have around 75%control over how well individuals age in body and *** is the real wealth and that everyone can significantly control/achieve sustainable health and quality of life through lifestyle choices needs to be better promoted. Dementia is predominantly a disease of aging with millions of people suffering from dementia and Alzheimer＇s disease （AD） and in recent years little has happened to change and improve the cognitive functions of elderly people （2015 Alzheimer＇s disease facts and figures）. Every 4 seconds there is a new case of dementia in the world and with 7.7 mil- lion cases annually, the estimated global cost of AD and demen- tia disease is $604 billion.

The recently developed elastic-viscoplastic self-consistent model with various self-consistent schemes was applied to study the effect of basal texture on the mechanical behavior of magnesium alloy AZ31B sheet. The influence of the basal texture was investigated using various initial textures generated by artificially tilting the measured texture of the reference AZ31B sheet around in a transverse direction. The material parameters for the various models were fitted to experimental uniaxial tension and compression along the rolling direction and were then used to study the effects of the basal texture on the yield stress, R value, ultimate stress and uniform strain under uniaxial tension. The effect of the basal texture on sheet metal forming was further assessed by calculating the limit strain under in-plane plane strain tension. An assessment of the predictive capability of polycrystal plasticity models was made based on comparisons of predictions and experimental observations. Among the available self-consistent approaches, the Affine self-consistent scheme resulted in the best overall performance.

Large strain fixed-end torsion of circular solid rubber bars is studied semi-analytically. The analyses are based on various non-Gaussian network models for rubber elasticity, some of which were proposed very recently. Results are presented in terms of predicted torque vs. twist curves and axial force vs. twist curves. In some cases, the predicted stress distributions are also given. The sensitivity of the second-order axial force to the employed models is considered. The predicted results are compared with experimental results found in the literature.

Dear Editor Previous research found that childhood cancer survivors of African ancestry have significantly higher morbidity and mortality than those of European ancestry[1].However,after adjusting for socio-economic factors,the magnitudes of racial health disparities are either substantially decreased or become statistically non-significant[1],suggesting that social and economic determinants may contribute to racial health ***,we conducted epigenome-wide association studies(EWAS)for three key social determinants of health(SDOHs),namely,personal educational attainment,personal income,and neighborhood deprivation among survivors of childhood cancer,where 130 epigenome-wide significant SDOH-CpG associationswere identified among European ancestry survivors,and 25 of which were also validated in African ancestry survivors[2].Notably,many SDOH-associated CpG sites are also associated with tobacco use.
