A big data approach to modelling urban population density functions: from monocentricity to polycentricity

open access: yesAnnals of GIS
Urban studies have a long tradition of examining the regularity of urban structure by modelling urban population density functions and probing the theoretical or behavioural foundation behind it.

Effect of Fiber Optic Plate on Centroid Locating Accuracy of Monocentric Imager

open access: yesApplied Sciences, 2021
We propose a method for obtaining the centroid locating accuracy (CLA) of a monocentric imager with a fiber optic plate (FOP) as a relay image transmission element in order to reduce the loss of CLA due to the addition of FOP.

What Will The Post-Pandemic City Look Like? [PDF]

open access: yesFindings, 2021
It is impossible to predict the future spatial structure of cities from our current models of location and travel behaviour for the forces that have previously determined where people locate, have been turned on their heads by the pandemic.

Urban spatial structure and environmental efficiency: Empirical analysis from prefecture-level cities in China

open access: yesFrontiers in Environmental Science, 2022
China’s environmental problems are emerging with the continuous development of the economy and urbanization. The study of the impact of urban spatial structure on environmental efficiency has important significance concerning exploring ways to reduce the

Inferring urban polycentricity from the variability in human mobility patterns

open access: yesScientific Reports, 2023
The polycentric city model has gained popularity in spatial planning policy, since it is believed to overcome some of the problems often present in monocentric metropolises, ranging from congestion to difficult accessibility to jobs and services. However,

Determinants of Urban Land Supply in the People's Republic of China: How Do Political Factors Matter? [PDF]

open access: yesAsian Development Review, 2017
This paper explores whether and how corruption and competition-for-promotion motives affect urban land supply in the People's Republic of China. Conditional on demand-side factors, we find that corruption is highly correlated with an increase in land ...

Holocentromeres can consist of merely a few megabase-sized satellite arrays

open access: yesNature Communications, 2023
The centromere is the chromosome region where microtubules attach during cell division. In contrast to monocentric chromosomes with one centromere, holocentric species usually distribute hundreds of centromere units along the entire chromatid.

A General Arthropod Joint Model and its Applications in Modeling Human Robotic Joints

open access: yesIEEE Access, 2021
Bearings are common rotational units, but these monocentric units do not realize high bio-imitability in exoskeleton robots. A common way to realize bionic motion is with an n-bar linkage mechanism within bearings, but the resultant joints can become ...

A deep learning model to generate synthetic CT for prostate MR-only radiotherapy dose planning: a multicenter study

open access: yesFrontiers in Oncology, 2023
IntroductionFor radiotherapy based solely on magnetic resonance imaging (MRI), generating synthetic computed tomography scans (sCT) from MRI is essential for dose calculation.

Influence of lipid rafts on pattern formation during T-cell adhesion

open access: yesNew Journal of Physics, 2021
Adhesion of T cells to antigen presenting cells is mediated by the TCR–MHCp and LFA1–ICAM1 protein complexes. These intercellular protein complexes segregate and form characteristic special patterns in the cell contact zone.
