The cosmological constant and oscillating metrics [PDF]

open access: yesJournal of High Energy Physics, 2002
The presence of a cosmological constant, Lambda, in an action with higher powers of the curvature can produce rapidly oscillating metrics. We develop a perturbative approach for generating periodic solutions to the non-linear field equations for such actions based on a small amplitude expansion.

Temporal variations in English Populations of a forest insect pest, the green spruce aphid (Elatobium abietinum), associated with the North Atlantic Oscillation and global warming [PDF]

open access: yes, 2007
Based on an exceptionally long modern ecological dataset (41 years), it has been possible to show that warm weather in England associated with a positive North Atlantic Oscillation (NAO) index causes the spring migration of the green spruce aphid ...

A sharp oscillation criterion for a difference equation with constant delay

open access: yesAdvances in Difference Equations, 2020
It is known that all solutions of the difference equation Δ x ( n ) + p ( n ) x ( n − k ) = 0 , n ≥ 0 , $$\Delta x(n)+p(n)x(n-k)=0, \quad n\geq0, $$ where { p ( n ) } n = 0 ∞ $\{p(n)\}_{n=0}^{\infty}$ is a nonnegative sequence of reals and k is a natural

High-frequency oscillations of Newton’s constant induced by inflation [PDF]

open access: yesPhysical Review D, 1995
We examine the possibility that an epoch of inflationary expansion induces high-frequency oscillations of Newton's constant, $G$. The effect occurs because inflation can shift the expectation value of a non-minimally coupled, Brans-Dicke-like field away from the minimum of its effective potential.

Measurement of neutrino oscillation parameters from muon neutrino disappearance with an off-axis beam [PDF]

open access: yes, 2013
The T2K Collaboration reports a precision measurement of muon neutrino disappearance with an off-axis neutrino beam with a peak energy of 0.6 GeV. Near detector measurements are used to constrain the neutrino flux and cross section parameters.
