Spatial Patterns and the Evolution of Logistics Service Node Facilities in Large Cities—A Case from Wuhan

ISPRS International Journal of Geo-Information
Logistics services are integral to urban economic activity, and delving into the spatial distribution traits and evolutionary pathways of various kinds of logistics service node facilities (LSNF) is markedly valuable for understanding a city’s functional

MRI texture features may predict differentiation and nodal stage of cervical cancer: a pilot study

Acta Radiologica Open, 2017
Background Texture analysis in oncological magnetic resonance imaging (MRI) may yield surrogate markers for tumor differentiation and staging, both of which are important factors in the treatment planning for cervical cancer.

Development of an Analytic Nodal Diffusion Solver in Multigroups for 3D Reactor Cores with Rectangular or Hexagonal Assemblies.

, 2009
More accurate modelling of physical phenomena involved in present and future nuclear reactors requires a multi-scale and multi-physics approach. This challenge can be accomplished by the coupling of best-estimate core-physics, thermal-hydraulics and ...

Edge‐Based Discretizations on Triangulations in Any Dimension, With Special Attention to Four‐Dimensional Space

International Journal for Numerical Methods in Fluids, EarlyView.
This article provides important geometric formulas for node‐centered, edge‐based schemes in any number of dimensions. These formulas are noteworthy, as they do not require the explicit formation of dual regions. We prove several key geometric results, with a particular focus on the four‐dimensional case, due to potential space‐time applications ...

Alterations in Brain Network Topology and Structural-Functional Connectome Coupling Relate to Cognitive Impairment

Frontiers in Aging Neuroscience, 2018
According to the network-based neurodegeneration hypothesis, neurodegenerative diseases target specific large-scale neural networks, such as the default mode network, and may propagate along the structural and functional connections within and between ...

Different Pattern of Treatment Failure After Chemoradiation Between p16+ and p16− Patients Affected by Oropharyngeal Carcinoma

Head &Neck, EarlyView.
ABSTRACT Background Oropharyngeal cancer (OPC) exhibits distinct clinical behaviors according to HPV/p16 status and smoking exposure. While HPV‐positive OPC generally shows superior survival, differences in recurrence patterns remain unclear. Methods A retrospective multicenter analysis of 674 AJCC VII edition Stage III–IVa/b OPC patients treated with ...
