Case Reports in Endocrinology, Volume 2025, Issue 1, 2025.Background: Familial hypocalciuric hypercalcemia type 3 (FHH3) is a rare hereditary disorder caused by a heterozygous AP2S1 gene mutation, characterized by hypocalciuria and hypercalcemia due to impaired intracellular signal transduction of calcium (Ca)‐sensing receptors (CaSRs).

The Yamabe Problem and Nonlinear Boundary Value Problems
Journal of Differential Equations, 1995 The paper is concerned with the scalar curvature equation with prescribed mean curvature on the boundary of a given Riemannian manifold. Just as in \textit{T. Ouyang} [Trans. Am. Math. Soc. 331, No. 2, 503-527 (1992; Zbl 0759.35021)], this Riemannian manifold is assumed to have negative constant scalar curvature in the interior and zero mean curvature ...

Further results on the fractional Yamabe problem: the umbilic case [PDF]
, 2014 preprintWe prove some existence results for the fractional Yamabe problem in the case that the boundary manifold is umbilic, thus covering some of the cases not considered by Gonz alez and Qing.

Comprehensive Safety Assessment of Hydrogen: From Production to Application in Energy Systems
International Journal of Energy Research, Volume 2025, Issue 1, 2025.In the quest for sustainable and clean energy alternatives to fossil fuels, hydrogen emerges as a front‐runner due to its high energy yield and environmentally friendly combustion byproduct, water. This study delves into the comprehensive lifecycle of hydrogen energy, from its production through various methods, storage, and transportation, to its ...

2‐Conformal Vector Fields on the Model Sol Space and Hyperbolic Ricci Solitons
Journal of Mathematics, Volume 2025, Issue 1, 2025.In this study, we present the notion of 2‐conformal vector fields on Riemannian and semi‐Riemannian manifolds, which are an extension of Killing and conformal vector fields. Next, we provide suitable vector fields in Sol space that are 2‐conformal. A few implications of 2‐conformal vector fields in hyperbolic Ricci solitons are investigated.

Compactness of solutions to the Yamabe problem
Comptes Rendus. Mathématique, 2004 We establish compactness of solutions to the Yamabe problem on any smooth compact connected Riemannian manifold (not conformally diffeomorphic to standard spheres) of dimension n ⩽7 as well as on any manifold of dimension n ⩾8 under some additional ...

Journal of the London Mathematical Society, Volume 110, Issue 5, November 2024.Abstract For large classes of even‐dimensional Riemannian manifolds (M,g)$(M,g)$, we construct and analyze conformally invariant random fields. These centered Gaussian fields h=hg$h=h_g$, called co‐polyharmonic Gaussian fields, are characterized by their covariance kernels k which exhibit a precise logarithmic divergence: |k(x,y)−log1d(x,y)|≤C$\big ...

Yamabe problem in the presence of singular Riemannian Foliations
, 2022 Using variational methods together with symmetries given by singular Riemannian foliations with positive dimensional leaves, we prove the existence of an infinite number of sign-changing solutions to Yamabe type problems, which are constant along the ...
