Background With the rapid growth of global aging, frailty has become a serious public health burden, affecting life quality older adults. Depressive symptoms (depression hereafter) and sleep are associated with frailty, but pathways in which depression affect remain unclear. Method This cross-sectional study included 1866 community-dwelling Demographic characteristics health-related data them was collected, we also assessed depression, quality. Descriptive statistics were carried out ordinal...
The dispersion of circumferential waves propagating around cylindrical and spherical underwater targets with an arbitrary number elastic fluid layers is modeled using the spectral collocation method. underlying differential equations are discretized by Chebyshev interpolation corresponding differentiation matrices, calculation curves transformed into a generalized eigenvalue problem. Furthermore, for in infinite fluid, perfect matched layer used to emulate Sommerfeld radiation condition. For...
Abstract Accelerator-based neutron sources are critical infrastructures in today's scientific research and industrial fields, with the source target being key component determining performance of source. Traditional accelerator targets typically use homogeneous elemental materials high yield as material. These face challenges terms operational lifespan under high-temperature high-radiation environments. The design next-generation brilliance demands better thermal conductivity, longer...
Objectives: Cognitive impairment among older adults is a significant public health concern worldwide. This study aims to investigate the prevalence of cognitive impairment, its correlates, and mediating role depressive symptoms between frailty in northeast region China. Methods: was cross-sectional which used intercept interview method recruit participants. Social demographic characteristic, health-related behaviours, physical health, functional status participants were collected. Univariate...
Through the study of thermal rheological behavior Ti6Al4V alloy at different temperatures (500 °C, 600 700 and 800 °C) strain rates (0.1 s−1, 0.05 0.01 0.005 s−1), a constitutive model was developed for across wide temperature range in hot stamping process. The model’s correlation coefficient reached 0.9847, indicating its high predictive accuracy. Hot processing maps suitable process were developed, demonstrating significant impact rate on formability alloy. At higher (>0.05 is less...
This research uses facial expression recognition software (FaceReader) to explore the influence of different sound interventions on emotions older people with dementia. The field experiment was carried out in public activity space an adult care facility. Three intervention sources were used, namely, music, stream, and birdsong. Data collected through Self-Assessment Manikin Scale (SAM) compared (FER) data. FaceReader identified differences emotional responses dementia revealed changes...
Creating a comfortable indoor environment in education buildings is an important design objective. Climate change has resulted rising summer temperatures the severe cold regions of China, and evidence overheating risk these not yet been fully investigated. This study presents university building region discusses potential integrated shading devices for mitigating overheating, proposes ideas application devices. Temperature monitoring simulation were performed with natural ventilation located...
External force at the end-effector is often required for control of robotic manipulator. In some cases, information measured by wrist sensor consists external and undesired inertial arising from acceleration end-effector. Up to now, it still difficult extract exactly insufficiency information. A novel six-axis accelerometer in type dual annular membranes structure presented this paper. It can simultaneously measure all three linear components ax, ay, az angular αx, αy, αz, which be used...
Abstract Background China has a high mortality from nasopharyngeal carcinoma (NPC). The NPC trends in 2006 to 2020 were described and analyzed understand its epidemiological characteristics by region sex explore age, period, cohort effects. Methods This study utilized data the Health Statistical Yearbook. A joinpoint regression model was used fit standardized age-specific mortality. age-period-cohort applied investigate effects on risk. Results results showed that rate been declining...
(1) Background: We aimed to analyze rheumatic heart disease (RHD) mortality trends in China's urban and rural areas determine the roles of age, period, cohort effects. (2) Methods: Based on data extracted from China Health Statistics Yearbook, we calculated crude rate RHD. Age-adjusted rates were computed by direct method using 2020 census as standard population. The annual percentage change (APC) average (AAPC) determined JoinPoint regression model. age-period-cohort model was used estimate...
Force sensors play a key role in the modern technological world, which can measure force information required for mechatronic systems used automated manufacturing environments to function effectively and make intelligent decisions. Aim decrease additional torque originated from height of sensors, we design thin six-dimensional senor is only 15 mm high. The sensor has simple geometry form double E-type membranes connected with four rectangle slices. also possesses advantages such as...
Abstract Roughness, which can represent the trade-off between manufacturing cost and performance of mechanical components, is a critical predictor cracks, corrosion fatigue damage. In order to measure polished or super-finished surfaces, novel touch probe based on three-component force sensor for characterizing quantifying surface roughness proposed by using silicon micromachining technology. The design cross-beam structure, ensures that system possesses high sensitivity low coupling....
Abstract Based on the platform of a proton accelerator facility, 200 MHz high intensity continuous wave (CW) radio frequency quadrupole (RFQ) has been designed at Sino-French Institute Nuclear Engineering and Technology Sun Yat-Sen University, China. Employing conventional four-vane structure, RFQ can accelerate 20 mA beam from keV to 2.5 MeV. In dynamics design, simulated transmission efficiency reaches 99.5% vane length is less than 4 m. electromagnetic for long-term stable operation,...
