Spatial structure governs the mode of tumour evolution

bioRxiv, 2019
Characterizing the mode—the way, manner or pattern—of evolution in tumours is important for clinical forecasting and optimizing cancer treatment. Sequencing studies have inferred various modes, including branching, punctuated and neutral evolution, but ...

Dark State Optical Lattice with a Subwavelength Spatial Structure [PDF]

Physical Review Letters, 2017
We report on the experimental realization of a conservative optical lattice for cold atoms with a subwavelength spatial structure. The potential is based on the nonlinear optical response of three-level atoms in laser-dressed dark states, which is not ...

A Multi-Feature Framework for Quantifying Information Content of Optical Remote Sensing Imagery

Remote Sensing, 2022
Quantifying the information content of remote sensing images is considered to be a fundamental task in quantitative remote sensing. Traditionally, the grayscale entropy designed by Shannon’s information theory cannot capture the spatial structure of ...

Synergistic effect of CaO and red mud on the water resistance of phosphogypsum-based cementitious materials

Case Studies in Construction Materials
To enhance the water resistance of phosphogypsum-based cementitious materials and promote solid-waste utilization, red mud (RM) was incorporated to develop phosphogypsum-based composites (RPG).

Substitutability, Spatial Structure, and Spatial Interaction [PDF]

Geographical Analysis, 1991
This paper attempts to distill the relationship among spatial structure, consumer preferences, and spatial interaction. It introduces the notion of substitutability. Destinations are substitutable in both economic‐behavioral and physical‐locational senses.

Effect of modifiers on the properties of bamboo scraps/magnesium oxychloride composites under dry-wet cycling environments

Case Studies in Construction Materials
Bamboo scraps/magnesium oxychloride composites (BS/MOC) is a new low-carbon and eco-friendly building material, which is composed of magnesium oxychloride cement (MOC) as the matrix and bamboo scraps as the reinforcing materials.

Detecting the Spatial Network Structure of the Guanzhong Plain Urban Agglomeration, China: A Multi-Dimensional Element Flow Perspective

Land, 2023
Element flow has gradually become an important method for studying urban spatial structure. This study examined 11 prefectural cities in the Guanzhong Plain urban agglomeration; constructed a measurement model for information, traffic, migration, and ...

Structural Information in Two-Dimensional Patterns: Entropy Convergence and Excess Entropy

, 2002
We develop information-theoretic measures of spatial structure and pattern in more than one dimension. As is well known, the entropy density of a two-dimensional configuration can be efficiently and accurately estimated via a converging sequence of ...
