Quantitative Studies for Cell-Division Cycle Control

Frontiers in Physiology, 2019
The cell-division cycle (CDC) is driven by cyclin-dependent kinases (CDKs). Mathematical models based on molecular networks, as revealed by molecular and genetic studies, have reproduced the oscillatory behavior of CDK activity.

Quantum theory of transition radiation and transition pair creation [PDF]

, 1998
Theory of the transition radiation and the transition pair creation is developed in the frame of QED. The spectral-angular distributions of probability of the transition radiation and of the transition pair creation are found.

Network Analysis Using Markov Chain Applied to Wildlife Habitat Selection

Diversity, 2022
In the present study, behavioral states for habitat selection are examined using a discrete-time Markov chain (DTMC) combined with a network model with wildlife movement data.

Gamma Limit for Transition Paths of Maximal Probability [PDF]

, 2011
Chemical reactions can be modelled via diffusion processes conditioned to make a transition between specified molecular configurations representing the state of the system before and after the chemical reaction.

MDPs with setwise continuous transition probabilities [PDF]

Operations Research Letters, 2021
This paper describes the structure of optimal policies for infinite-state Markov Decision Processes with setwise continuous transition probabilities. The action sets may be noncompact. The objective criteria are either the expected total discounted and undiscounted costs or average costs per unit time.

Transition patterns of weight status: A cohort study of Chinese school-age children

Frontiers in Public Health, 2022
BackgroundChildhood overweight and obesity are increasing public concerns. However, little is known about the transition patterns of childhood weight status, especially in developing countries.

Cosmological dynamics in tomographic probability representation

, 2004
The probability representation for quantum states of the universe in which the states are described by a fair probability distribution instead of wave function (or density matrix) is developed to consider cosmological dynamics.

Transition times in the Landau-Zener model [PDF]

, 1998
This paper presents analytic formulas for various transition times in the Landau-Zener model. Considerable differences are found between the transition times in the diabatic and adiabatic bases, and between the jump time (the time for which the ...

Transitional Strength under Plasma: Precise Estimations of Astrophysically Relevant Electromagnetic Transitions of Ar⁷⁺, Kr⁷⁺, Xe⁷⁺, and Rn⁷⁺ under Plasma Atmosphere

Atoms, 2023
The growing interest in atomic structures of moderately stripped alkali-like ions in the diagnostic study and modeling of astrophysical and laboratory plasma makes an accurate many-body study of atomic properties inevitable. This work presents transition

A Noncentral Lindley Construction Illustrated in an INAR(1) Environment

Stats, 2022
This paper proposes a previously unconsidered generalization of the Lindley distribution by allowing for a measure of noncentrality. Essential structural characteristics are investigated and derived in explicit and tractable forms, and the estimability ...
