Thermodynamic and Differential Entropy under a Change of Variables

open access: yesEntropy, 2010
The differential Shannon entropy of information theory can change under a change of variables (coordinates), but the thermodynamic entropy of a physical system must be invariant under such a change.

Connectivity and physical activity: using footpath networks to measure the walkability of built environments

open access: yes, 2016
There is now a strong body of research that suggests that the form of the built environment can influence levels of physical activity, leading to an increasing interest in incorporating health objectives into spatial planning and regeneration. There have

Fermionic SPT phases in higher dimensions and bosonization

open access: yesJournal of High Energy Physics, 2017
We discuss bosonization and Fermionic Short-Range-Entangled (FSRE) phases of matter in one, two, and three spatial dimensions, emphasizing the physical meaning of the cohomological parameters which label such phases and the connection with higher-form ...

Modeling Urban Growth and Form with Spatial Entropy

open access: yesComplexity, 2020
Entropy is one of the physical bases for the fractal dimension definition, and the generalized fractal dimension was defined by Renyi entropy. Using the fractal dimension, we can describe urban growth and form and characterize spatial complexity.

Explanation of the architectural and spatial pattern in the plans of the historical mosques of Hormozgan

open access: yesطراحی و برنامه ریزی در معماری و شهرسازی
The structure of historical contexts comprises spatial organization and pedestrian context, movement paths with patterns, spaces with various functions, and historical buildings. These elements define the physical-spatial pattern.

Entorhinal cortex receptive fields are modulated by spatial attention, even without movement

open access: yesbioRxiv, 2017
Grid cells have been identified in the entorhinal cortex in a variety of species and allow for the precise decoding of position in space (1–7). Along with potentially playing an important role in navigation, grid cells have recently been hypothesized to ...

Toward a mathematical approach of spatial permeability (Kyrillos's Model)

open access: yesComputational Urban Science
Spatial permeability is a distinctive characteristic of urban form. However, a definitive method for measuring it remains a challenge. This study aims to investigate factors affecting permeability within urban systems, with a focus on incorporating a ...

Influence of Heat Sources and Relaxation Time on Temperature Distribution in Tissues

open access: yesInternational Journal of Applied Mechanics and Engineering, 2014
In the present study, the temperature fluctuations in tissues based on Penne’s bio-heat transfer equation is investigated by applying the Laplace and Hankel transforms.

Assessing Active Living Potential: Case Study of Jacksonville, Florida

open access: yesUrban Science, 2018
Many municipalities in the US are deploying urban planning approaches to resolve problems caused by urban sprawl, particularly the lack of support for physical activity. Although a variety of perspectives on the relationship between physical activity and

SPATIAL STRUCTURE OF WATERFRONT CITIES: COMPARISSON BETWEEN KENDARI AND MANADO

open access: yesTataloka, 2016
As an archipelagic country, many cities in Indonesia exist and grow at the waterfronts. This research aims to explore comparatively the spatial structure of two waterfront cities: Kendari represents a bay-front with U-form coast line, and Manado as a sea-
