Computation of a combined spherical-elastic and viscous-half-space earth model for ice sheet simulation [PDF]
This report starts by describing the continuum model used by Lingle & Clark (1985) to approximate the deformation of the earth under changing ice sheet and ocean loads.

We study the half-linear neutral differential equation \begin{equation*} \Bigl[r(t)\Phi(z'(t))\Bigr]'+c(t)\Phi(x(\sigma(t)))=0, \qquad z(t)=x(t)+b(t)x(\tau(t)), \end{equation*} where $\Phi(t)=|t|^{p-2}t$.

New Criteria for Sharp Oscillation of Second-Order Neutral Delay Differential Equations
In this paper, new oscillation criteria for second-order half-linear neutral delay differential equations are established, using a recently developed method of iteratively improved monotonicity properties of a nonoscillatory solution. Our approach allows

Half-linear discrete oscillation theory
Oscillatory properties of the second order half-linear difference equation $$\Delta(r_k|\Delta y_k|^{\alpha-2}\Delta y_k)+p_k|y_{k+1}|^{\alpha-2}y_{k+1}=0,$$ where $\alpha>1$, are investigated.

A sharp oscillation result for second-order half-linear noncanonical delay differential equations
In the paper, new single-condition criteria for the oscillation of all solutions to a second-order half-linear delay differential equation in noncanonical form are obtained, relaxing a traditionally posed assumption that the delay function is ...

Oscillation of half-linear differential equations with mixed type of argument
This paper is devoted to the study of the oscillatory behavior of half-linear functional differential equations with deviating argument of the form \begin{equation*}\label{Eabs} \left(r(t)(y'(t))^{\alpha}\right)'=p(t)y^{\alpha}(\tau(t)). \tag{$E$} \end{

Oscillation and nonoscillation of second-order half-linear differential equations [PDF]
The paper considers the problem of oscillation and non-oscillation of the second order half-linear differential equation \[ ({|{u'(t)}|}^{\alpha-1}u'(t))'+p(t){|{u'(t)}|}^{\alpha-1}u(t)=0, \] where \(\alpha>0\) is a constant and \(p\in C([0,+\infty),[0,+\infty))\) is an integrable function.

Nonoscillatory solutions of planar half-linear differential systems: a Riccati equation approach
In this paper an attempt is made to depict a clear picture of the overall structure of nonoscillatory solutions of the first order half-linear differential system \begin{equation*} x'-p(t)\varphi_{1/\alpha}(y)=0,\qquad y'+q(t)\varphi_{\alpha}(x)=0, \tag{

Mapping the evolution of mitochondrial complex I through structural variation
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
