Simulation of spatiotemporal patterns of habitat quality and driving mechanism in Anhui province, China

open access: yesFrontiers in Environmental Science, 2023
Understanding the characteristics of habitat quality and its influence under land use change is crucial for rapid urbanization, regional ecological protection, and national restoration and optimization of the ecological layout.

Averaging plus learning models and their asymptotics

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023
We develop original models to study interacting agents in financial markets and in social networks. Within these models, randomness is vital as a form of shock or news that decays with time. Agents learn from their observations and learning ability to interpret news or private information in time-varying networks. Under general assumptions on the noise,

A Max-Plus Model of Asynchronous Cellular Automata [PDF]

open access: yesComplex Systems, 2014
This paper presents a new framework for asynchrony. This has its origins in our attempts to better harness the internal decision making process of cellular automata (CA). Thus, we show that a max-plus algebraic model of asynchrony arises naturally from the CA requirement that a cell receives the state of each neighbour before updating.

Dirac plus Nambu monopoles in the Standard Model [PDF]

open access: yesPhysical Review D, 2021
We show how in the standard electroweak model three $SU(2)_L$ Nambu monopoles, each carrying electromagnetic (EM) and Z- magnetic fluxes, can merge (through Z-strings) with a single $U(1)_Y$ Dirac monopole to yield a composite monopole that only carries EM magnetic flux.

Spatial and temporal changes in land and water resources on the northern slopes of the Tianshan mountains from the perspective of “production-living-ecological space”

open access: yesFrontiers in Environmental Science, 2023
The rapidly growing social demand for water and land, along with increasingly constraining economic and social development, have intensified the conflicts between regional production, living, and ecological spaces (PLES).
