On Sequences of Numbers and Polynomials Defined by Linear Recurrence Relations of Order 2

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
Here we present a new method to construct the explicit formula of a sequence of numbers and polynomials generated by a linear recurrence relation of order 2.

Can species adapt to drought using multiple strategies? Lessons from the California poppy

open access: yesNew Phytologist, EarlyView.
Summary Plants can escape drought by completing life cycles early, tolerate drought by increasing physiological limits, or avoid drought stress by obtaining or using water more efficiently. It remains unclear whether strategies vary within species across their distributional ranges due to trade‐offs, and whether species can exhibit plasticity in ...

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

open access: yesNew Phytologist, EarlyView.
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

On the Lucas polynomials and some of their new identities

open access: yesAdvances in Difference Equations, 2018
The main purpose of this paper is, using the elementary and combination methods, to study the arithmetical properties of the Lucas polynomials and to obtain some new and interesting identities for them.

Forecasting Climate Change Using a Multivariate Cointegrated System

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT A cointegrated vector equilibrium correction model of key climate variables including sea surface temperature, ocean heat content, Arctic sea‐ice extent and sea‐level change is built, driven by radiative forcing in which a stochastic trend arises due to anthropogenic emissions of greenhouse gases.

Numerical Solutions for Nonlinear Ordinary and Fractional Duffing Equations Using Combined Fibonacci–Lucas Polynomials

open access: yesAxioms
Two nonlinear Duffing equations are numerically treated in this article. The nonlinear fractional-order Duffing equations and the second-order nonlinear Duffing equations are handled.

Jumping on the moon as a potential exercise countermeasure

open access: yesExperimental Physiology, EarlyView.
Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...

A generalization of Lucas polynomial sequence

open access: yesDiscrete Applied Mathematics, 2009
The authors consider the problem of a generalization of Lucas polynomial sequence. They obtain a generalized Lucas polynomial sequence from the lattice paths for the Delannoy numbers by allowing weights on the steps \((1,0),(0,1)\) and \((1,1)\).
