New examples of complete Ricci solitons
, 1994 The Ricci soliton condition reduces to a set of ODEs when one assumes that the metric is a doubly-warped product of a ray with a sphere and an Einstein manifold.

A Digital Anatomical Atlas of the Human Cerebellum at Subfolial Resolution
Human Brain Mapping, Volume 47, Issue 4, March 2026.We present a digital atlas of the human cerebellum at subfolial resolution with both volumetric and surface representations, offering an anatomical ground‐truth reference at unprecedented granularity. ABSTRACT Interest in the cerebellum has surged with the emerging consensus that it supports diverse functions that are topographically arranged across ...

Human Brain Mapping, Volume 47, Issue 4, March 2026.The near‐silent Looping Star fMRI sequence is validated and directly compared to standard EPI in a degraded speech paradigm. Combined‐echo LS yielded larger BOLD activation clusters which extended into key regions associated with effortful processing of degraded speech (insula, precentral gyrus, IFG), while standard EPI and single‐echo LS did not ...

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1462-1477, March 2026.ABSTRACT Purpose To develop a fat‐water separation approach that corrects bipolar readout gradient‐induced effects without additional scans and is compatible with any fat‐water separation method. Theory and Methods The proposed approach combines joint fat‐water separation of the odd and even echoes of a bipolar multi‐echo gradient echo acquisition with

International Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.ABSTRACT This work presents a fully thermomechanically coupled material model for shape memory alloys (SMAs), capable of predicting shape memory effect, superelasticity, stress and strain recovery, and martensite reorientation. Formulated within the Generalized Standard Material (GSM) framework, the model employs a rate potential, whose variations ...

Doubly Warped Products in Locally Conformal Almost Cosymplectic Manifolds
International Electronic Journal of Geometry, 2017 Recently, the author established a general inequality for doubly warped products in arbitraryRiemannian manifolds [16]. In the present paper, we obtain similar inequalities for doublywarped products isometrically immersed in locally conformal almost cosymplectic manifolds.Some applications are derived.

Curvature analysis of concircular trajectories in doubly warped product manifolds
AIMS Mathematics<p>The aim of this research paper was to explore the various characteristics of the doubly warped product manifold, focusing particularly on aspects such as the Hessian, Riemannian curvature, Ricci curvature, and concircular curvature tensor components.
