Non-singular, vacuum, stationary space-times with a negative cosmological constant

open access: yes, 2005
We construct infinite dimensional families of non-singular stationary space times, solutions of the vacuum Einstein equations with a negative cosmological constant.Comment: minor corrections, an inessential uniqueness claim ...

Modeling delay in genetic networks: From delay birth-death processes to delay stochastic differential equations [PDF]

open access: yes, 2014
Delay is an important and ubiquitous aspect of many biochemical processes. For example, delay plays a central role in the dynamics of genetic regulatory networks as it stems from the sequential assembly of first mRNA and then protein.

Non-singular spacetimes with a negative cosmological constant: III. Stationary solutions with matter fields

open access: yes, 2017
Generalising the results in arXiv:1612.00281, we construct infinite-dimensional families of non-singular stationary space times, solutions of Yang-Mills-Higgs-Einstein-Maxwell-Chern-Simons-dilaton-scalar field equations with a negative cosmological ...

Delay-dependent exponential stability of neutral stochastic delay systems [PDF]

open access: yes, 2009
This paper studies stability of neutral stochastic delay systems by linear matrix inequality (LMI) approach. Delay dependent criterion for exponential stability is presented and numerical examples are conducted to verify the effectiveness of the proposed

Impact of early chest radiography on delay in pulmonary tuberculosis case notification in Ethiopia

open access: yesInternational Journal of Mycobacteriology, 2021
Background: One-third of tuberculosis (TB) cases are missed each year and delays in the diagnosis of TB are hampering the whole cascade of care. Early chest X-ray (CXR) in patients with cough irrespective of duration may reduce TB diagnostic and ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...
