Switching and diffusion models for gene regulation networks [PDF]

open access: yes, 2009
We analyze a hierarchy of three regimes for modeling gene regulation. The most complete model is a continuous time, discrete state space, Markov jump process.

Risk Prediction and Optimal Control of Waterlogging in Urban Land Based on PLUS-SCS Model

open access: yesShuitu baochi tongbao, 2023
[Objective] The urban land use in the future and corresponding waterlogging risk intensity was predicted, and the optimal control of the waterlogging risk and its implementation effects was explored in order to provide references for improving the ...

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.

QRPA plus Phonon Coupling Model and the Photoabsorbtion Cross Section for $^{18,20,22}$O [PDF]

open access: yes, 2001
We have calculated the electric dipole strength distributions in the unstable neutron rich oxygen isotopes $^{18,20,22}$O, in a model which include up to four quasi-particle-type configurations.

PLUS-Model Based Multi-Scenario Land Space Simulation of the Lower Yellow River Region and Its Ecological Effects

open access: yesSustainability, 2022
The rapid urbanization in recent years as a vehicle for social growth and ecological construction has resulted in a significant transformation of the spatial structure of the land in the lower reaches of the Yellow River. Based on this, the current study

Search for the standard model Higgs boson in tau final states [PDF]

open access: yes, 2009
We present a search for the standard model Higgs boson using hadronically decaying tau leptons, in 1 inverse femtobarn of data collected with the D0 detector at the Fermilab Tevatron ppbar collider. We select two final states: tau plus missing transverse

On thermal phase structure of deformed Gross-Neveu model [PDF]

open access: yes, 1996
We illustrate the phase structure of a deformed two-dimensional Gross-Neveu model which is defined by undeformed field contents plus deformed Pauli matrices.

How the nuclear Fermi motion plus a simple statistical model explains the EMC effect [PDF]

open access: yes, 2002
We present calculation of influence caused by nucleon Fermi motion on the parton distributions in nuclei. Our approach is based on the model where momenta of valence partons have some primordial distribution inside the hadron at rest, which is either ...

The spatial prediction and optimization of production-living-ecological space based on Markov–PLUS model: A case study of Yunnan Province

open access: yesOpen Geosciences, 2022
Production-living-ecological space (PLES) reflects the main function of land use types. It is one of the main directions that many scholars researched to evaluate, predict, and optimize the land space from the perspective of PLES.

Spatial-Temporal Evolution and Driving Forces of Cultivated Land based on the PLUS Model: A Case Study of Haikou City, 1980–2020

open access: yesSustainability, 2022
The security of cultivated land is the foundation for stable social and economic development. In recent years, with rapid economic development, urbanization around the world has been accelerating. The demand for urban construction expansion is increasing
