Flexible drop-off and pick-up (one-way) carsharing programs provide users with high levels of convenience but meanwhile incurs spatiotemporal imbalances in shared-cars distribution. Predicting shared-car use helps recognize system beforehand while identifying determinants related to operators efficiently implement relocation strategies. In this study, a gradient boosting regression model (GBRT) is employed predict at station level, partial dependence plots (PDPs) are examine nonlinear...

Aim: Promoting walking activity is an effective way to improve the health of older adults. Walking frequency a critical component behavior and essential determinant daily levels. To decipher association between built environment among adults, this study's aims are as follows: (1) empirically test whether non-linear relationships two exist, (2) identify thresholds characteristics that promote walking. Methods: The old adults was derived from Zhongshan Household Travel Survey (ZHTS) in 2012....

Growing international trade has been one of the most important drivers for China's recent economic growth. This growth fed rapid increases in energy demand and carbon emissions since 2000. China is now world's largest emitter dioxide. There mounting pressure from some community to take specific actions mitigate its as part a post-2012 climate regime. However, embodied internationally traded goods have not given enough attention this debate. article discusses results research quantify...

Abstract Heavy traffic volume coupled with insufficient capacity due to limited space cause most of congestion at urban signalized intersections. This article presents an innovative design increase the heavily congested intersections by using special width approach lane (SWAL), which consists two narrow lanes that are dynamically utilized either passenger cars or a heavy vehicle (e.g., buses trucks) depending on composition traffic. The impact SWAL saturation flow rate is quantified and...

Global aging has raised increasing concerns on the health and well-being of older adults. Public transport is a viable option to improve mobility quality life among However, policies that promote public use adults are rare. This study utilizes eXtreme Gradient Boosting (XGBoost) decision tree explore non-linear associations built social environment with bus in China. The was obtained from Zhongshan Household Travel Survey (ZHTS) 2012. Results show relationships exist all characteristics....

Walking plays a crucial role in promoting physical activity among older adults. Understanding how the built environment influences adults' walking behavior is vital for and healthy aging. Among voluminous literature investigating environmental correlates of behaviors adults, few have focused on duration across different age groups life stages, let alone examined potential nonlinearities thresholds environment.

Spatial big data about human mobility have been employed intensively in understanding spatial activity patterns, which is a central topic many applications. Available research on clustering patterns of activities has investigated mainly based similarities locations and temporal attributes trajectories. These methods are not effective revealing groups who move among spaces at different but with the same functions. Function, as one semantic attribute spaces, major driver most movements. This...

Antibodies have been widely used globally over the past decade and play an increasingly important role in modern medicine. Notably, significant advancements achieved realm of gynecology, particularly gynecological cancers. This study endeavors to present a thorough overview antibody-related drug clinical studies gynecology registered on ClinicalTrials.gov , focusing basic characteristics trials, geographical distribution, administration routes, indications, targets. The analysis indicates...

The health and welfare of older adults have raised increasing attention due to global aging. Cycling is a physical activity mode transportation enhance the mobility quality life among adults. Nevertheless, planning strategies promote cycling are underutilized. Therefore, this paper describes nonlinear associations built environment with frequency data were collected from Zhongshan Household Travel Survey (ZHTS) in 2012. modeling approach was eXtreme Gradient Boosting (XGBoost) model....

Public transport improves mobility and well-being for the rapidly aging population. However, few planning interventions have addressed urban–rural disparity in bus usage among older adults. Using data from Zhongshan, China, this study adopts eXtreme Gradient Boosting (XGBoost) model to examine differences nonlinear relationship between built environment daily elderly The results indicate nonlinearities across all variables stronger effects of rural areas. Distance transit contributes most...

The purpose of our study is to evaluate sagittal parameters in 2-level lumbar degenerative spondylolisthesis (DS) (TLDS). A total 15 patients with TLDS, 40 single-level DS (SLDS), and 30 normal volunteers as control were included study. All subjects performed on full spine X-ray. Two categorized data analyzed: patient characteristics—age, sex, body mass index, radiographic parameters-pelvic incidence (PI), pelvic tilt (PT), lordosis (LL), sacral slope (SS), PI–LL, Cobb between the fifth...

This study is aimed at investigating the resilience degradation caused by traffic accidents and developing relevant optimization strategies. A two-stage accident triangle framework was proposed comparing differences between natural disasters accidents. To maximize system resilience, a network-wide signal model presented. Spillback constraints equilibrium were established to enhance capacity of urban-road networks minimize congestion escalation, in addition rapid recovery. two-level algorithm...

Smart City (SC) is a booming model of urban development with great potential, armed to be one the development’s most powerful developing weapons. However, SC far from satisfactory. Therefore, finding new paths for becomes imperative. Transit Oriented Development (TOD), which often focuses on core areas SC, believed substantial contributor SC. Nonetheless, relationship between and TOD effects in promoting are rarely studied. In this study, we proposed conceptual framework (S-TOD), could...

Sex differences in Alzheimer's disease and mild cognitive impairment have been well recognized. However, sex function obesity cognitively normal aging Chinese Han population not attracted much attention.The aim of this study was to investigate the relationship between sex, obesity, an elderly with function.A total 228 participants (males/females =93/135) entered study. Their general demographic information (sex, age, education) collected by standardized questionnaire. Apolipoprotein E (APOE)...

As a typical and special type of urban setting, the university campus usually faces similar challenges as cities raised by high-density inhabitants. The smart has been introduced based on city, concepts, technologies, solutions to improve livability energy efficiency. Inhabitants’ occupancy in buildings open spaces is critical optimize management services.
