Measuring Unmet Need for Contraception Using a Person‐Centered Algorithm: An Application With a Community‐Based Sample of Married Rohingya Women in Bangladesh

Studies in Family Planning, EarlyView.
Abstract The standard measure of unmet need for contraception is not person‐centered and may not adequately represent women's contraceptive needs. To demonstrate the strength of a modified measure, we replicated the standard algorithm for unmet need, then created a person‐centered algorithm that considers (1) whether nonusers want to use contraception ...

Uniqueness on average of large isoperimetric sets in noncompact manifolds with nonnegative Ricci curvature

Communications on Pure and Applied Mathematics, Volume 78, Issue 9, Page 1656-1702, September 2025.
Abstract Let (Mn,g)$(M^n,g)$ be a complete Riemannian manifold which is not isometric to Rn$\mathbb {R}^n$, has nonnegative Ricci curvature, Euclidean volume growth, and quadratic Riemann curvature decay. We prove that there exists a set G⊂(0,∞)$\mathcal {G}\subset (0,\infty)$ with density 1 at infinity such that for every V∈G$V\in \mathcal {G}$ there ...

Disruption of Drought Teleconnections Between ENSO‐Influenced Regions Around 1700 CE

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Our understanding of pre‐modern El Niño Southern Oscillation (ENSO) variability is reliant on proxy records, often distant from the center of ENSO activity in the equatorial Pacific Ocean. Here, we assess the relationship between reconstructed soil moisture in four distant ENSO‐influenced regions over the past 400 years.

A Transference Result of the Lp-Continuity of the Jacobi Littlewood-Paley g-Function to the Gaussian and Laguerre Littlewood-Paley g-Function

Journal of Function Spaces, 2018
We develop a transference method to obtain the Lp-continuity of the Gaussian-Littlewood-Paley g-function and the Lp-continuity of the Laguerre-Littlewood-Paley g-function from the Lp-continuity of the Jacobi-Littlewood-Paley g-function, in dimension one,
