Population and Development Review, Volume 52, Issue 2, Page 299-318, June 2026.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.

Uniqueness of a positive solution for quasilinear elliptic equations in Heisenberg group
Electronic Journal of Differential Equations, 2016 In this note we address the question of uniqueness of the Brezis-Oswald problem for the p-Laplacian operator in Heisenberg Group.

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract High‐altitude optical meteors initiating above 150 km are exceedingly rare, with confirmed observations largely confined to the Leonids. Using the Meteor and ionospheric Irregularity Observation System, we recorded a bright 43‐Cassiopeiids fireball with heterogeneous material. It initiated luminously at an exceptional altitude of 157.8 ± $\pm $

Picone-type identity for pseudo \(p\)-Laplacian with variable power
Electronic Journal of Differential Equations, 2012 Summary: A Picone type identity is established for homogeneous differential operators involving the pseudo \(p\)-Laplacian with variable exponent \(p=p(x)\). Using this identity, it is shown that the classical Sturmian theory extends to the associated partial differential equations.

ANISOTROPIC PICONE IDENTITIES FOR HALF LINEAR CONFORMABLE ELLIPTIC EQUATIONS
JOURNAL OF MECHANICS OF CONTINUA AND MATHEMATICAL SCIENCESThis study is devoted to investigating the anisotropic picone identities for half-linear Conformable elliptic equations and the Hardy-type inequality. Further, we provide some results for the nonlinear analogue to Picone identity.

Picone's Identity for $p$-biharmonic operator and Its Applications
, 2015 In this article we prove the nonlinear analogue of Picone's identity for $p-$biharmonic operator. As an application of our result we show that the Morse index of the zero solution to a $p-$biharmonic boundary value problem is $0$. We also prove a Hardy type inequality and Sturmian comparison principle.

Sturmian comparison theory for half‐linear and nonlinear differential equations via Picone identity
Mathematical Methods in the Applied Sciences, 2016 In this paper, Sturmian comparison theory is developed for the pair of second‐order differential equations; first of which is the nonlinear differential equations of the form urn:x-wiley:mma:media:mma4224:mma4224-math-0001 and the second is the half‐linear differential equations urn:x-wiley:mma:media:mma4224:mma4224-math-0002 where Φα(s) = |s|α −

Picone Identities of a Certain Class of Conformable Half Linear Anisotropic Biharmonic Equations
Malaysian Journal of Fundamental and Applied SciencesMain aim of this article, we derive sufficient conditions of new results for Picone identities for a certain class of conformable half-linear anisotropic biharmonic equations. We derive a Strumiancomparison theorem and oscillation results. Furthermore, the oscillation results are different from the most known ones in the sense that they are based on ...
