Instability of Vertical Constant Through Flows in Binary Mixtures in Porous Media with Large Pores
Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019 A binary mixture saturating a horizontal porous layer, with large pores and uniformly heated from below, is considered. The instability of a vertical fluid motion (throughflow) when the layer is salted by one salt (either from above or from below) is analyzed.

EIGENVALUES OF THE p-LAPLACIAN AND DISCONJUGACY CRITERIA [PDF]
, 2006 We derive oscillation and nonoscillation criteria for the one-dimensional p-Laplacian in terms of an eigenvalue inequality for a mixed problem. We generalize the results obtained in the linear case by Nehari and Willett, and the proof is based on a ...

Population and Development Review, EarlyView.Abstract There are striking disparities in life expectancy across sociodemographic groups in the United States, shaped by structural forces such as racism, class inequality, and policy environments. To what extent do sociodemographic characteristics structure—or fail to structure—individual lifespans? Using U.S.

Identification of Fully Measurable Grand Lebesgue Spaces
Journal of Function Spaces, Volume 2017, Issue 1, 2017., 2017 We consider the Banach function spaces, called fully measurable grand Lebesgue spaces, associated with the function norm ρ(f) = ess supx∈Xδ(x)ρp(x)(f), where ρp(x) denotes the norm of the Lebesgue space of exponent p(x), and p(·) and δ(·) are measurable functions over a measure space (X, ν), p(x)∈[1, ∞], and δ(x)∈(0,1] almost everywhere. We prove that

Comparison results for two-dimensional half-linear cyclic differential systems [PDF]
, 2017 summary:Two identities of the Picone type for a class of half-linear differential systems in the plane are established and the Sturmian comparison theory for such systems is developed with the help of these new ...

Transactions of the Institute of British Geographers, Volume 51, Issue 1, March 2026.Abstract This article develops a cultural political ecology approach to disarticulations and labour unrest. The reference point for analysis is a struggle at a Whirlpool factory in Naples that the company announced would close in 2019, six months after signing an agreement with the Italian government, including a multi‐million investment plan.

Discrete Dynamics in Nature and Society, Volume 2016, Issue 1, 2016., 2016 We study the existence of nodal solutions for the following problem: −x″ = αx+ + βx− + ra(t)f(x), 0 < t < 1, x(0) = x(1) = 0, where r ≠ 0 is a parameter, a(t) ∈ C([0,1], (0, ∞)) with a(t)≢0 on any subinterval of [0,1], x+ = max{x, 0}, x− = −min{x, 0}, and α, β ∈ C[0,1]; f∈C(R,R), sf(s) > 0 for s ≠ 0, and f0, f∞ ∉ (0, ∞), where f0 = lim|s|→0f(s)/s and f∞

Advances in Mathematical Physics, Volume 2016, Issue 1, 2016., 2016 A comparison between first‐order microscopic and macroscopic differential models of crowd dynamics is established for an increasing number N of pedestrians. The novelty is the fact of considering massive agents, namely, particles whose individual mass does not become infinitesimal when N grows.

Bifurcation for indefinite‐weighted p$p$‐Laplacian problems with slightly subcritical nonlinearity
Mathematische Nachrichten, Volume 297, Issue 11, Page 3982-4002, November 2024.Abstract We study a superlinear elliptic boundary value problem involving the p$p$‐Laplacian operator, with changing sign weights. The problem has positive solutions bifurcating from the trivial solution set at the two principal eigenvalues of the corresponding linear weighted boundary value problem.
