Enhanced observability of quantum post-exponential decay using distant detectors [PDF]

open access: yes, 2009
We study the elusive transition from exponential to post-exponential (algebraic) decay of the probability density of a quantum particle emitted by an exponentially decaying source, in one dimension. The main finding is that the probability density at the

Network Analysis Using Markov Chain Applied to Wildlife Habitat Selection

open access: yesDiversity, 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.

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

open access: yesFrontiers 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.

Net quark number probability distribution near the chiral crossover transition [PDF]

open access: yes, 2013
We investigate properties of the probability distribution of the net quark number near the chiral crossover transition in the quark-meson model. The calculations are performed within the functional renormalization group approach, as well as in the mean ...

Generalizations of Wigner's theorem from rank-$ 1 $ projections to rank-$ n $ projections

open access: yesElectronic Research Archive
We provide generalizations of the classical Wigner's theorem as well as Uhlhorn's version of Wigner's theorem by considering maps that send rank-$ 1 $ projections to rank-$ n $ projections.

Transition probabilities and measurement statistics of postselected ensembles

open access: yes, 2010
It is well-known that a quantum measurement can enhance the transition probability between two quantum states. Such a measurement operates after preparation of the initial state and before postselecting for the final state.

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

open access: yesAtoms, 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

open access: yesStats, 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 ...

Fragmentation and the Bose-glass phase transition of the disordered 1D Bose gas

open access: yes, 2010
We investigate the superfluid-insulator quantum phase transition in a disordered 1D Bose gas in the mean field limit, by studying the probability distribution of the density.

Magnetic Multipole Transition Probabilities [PDF]

open access: yesHighlights of Astronomy, 1971
AbstractA review is given of the occurrence and transition probabilities of spectrum lines arising from magnetic quadrupole radiation. Magnetic dipole radiation in relativistic quantum mechanics is also discussed.
