T2$$ {\boldsymbol{T}}_{\mathbf{2}} $$‐Weighted Imaging of Water, Fat and Silicone
ABSTRACT Purpose Magnetic resonance imaging (MRI) is a sensitive method for assessing silicone implant integrity, with T2$$ {T}_2 $$‐weighted imaging being essential for detecting abnormalities in surrounding tissue. Silicone breast imaging protocols often require multiple tailored sequences for species suppression and diagnostic contrast. We propose a

ABSTRACT Purpose To achieve high resolution (≤ 1 mm isotropic) whole‐brain perfusion imaging at 7 T with next generation ASL pulse sequence, reconstruction algorithm, and MRI hardware. Methods We capitalized on three major innovations: (1) FLASH‐based pseudo‐Continuous ASL (pCASL) sequence with rotated golden‐angle stack‐of‐spirals (rGA‐SoS) sampling; (

Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs
Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure

Perfect Roman and Perfect Italian Domination of Cartesian Product Graphs
For a graph G=(V,E), a function f:V→{0,1,2} is a perfect Roman dominating function (PRDF) on G if every v∈V with f(v)=0 is adjacent to exactly one vertex u with f(u)=2. The sum ∑_(v∈V)^▒f (v) is the weight w(f) of f.

Automatic Respiratory and Bulk Patient Motion Corrected 3D Fetal MRI
ABSTRACT Purpose To develop a framework (ACROBATIC) for correcting motion in 3D radial fetal MRI. Methods Data were simulated (N = 200) and acquired in utero (N = 11, gestational age: 32 ± 2 weeks). Motion due to maternal respiration was estimated by extracting a self‐gating signal and applying focused navigation. Bulk motion was estimated by splitting

A-vertex magicness of product of graphs
In this paper, we discuss the A-vertex magicness of some products of graphs, where A is a non-trivial additive Abelian group with identity 0. We characterize A-vertex magicness of the Cartesian product of Pn and Pm, where A has at least three elements ...

ABSTRACT Purpose In multi‐shot EPI, shot‐dependent phase fluctuations can introduce ghost artifacts, undermining advantages for enhancing resolution or reducing distortion, particularly in diffusion scans. Here, a novel self‐navigation strategy based on shift‐invariant kernel extraction is proposed, enabling robust estimation of phase inconsistencies ...

Analyzing Nicotine Action Against Amyloid Toxicity by NMR‐Pharmacometabolomics: An Exploratory Study
Combined metabolomic analysis of the intracellular and extracellular portions of SH‐SY5Y cells revealed that, in the presence of Aβ 1–42, nicotine primarily influences pathways related to neurotransmission, energy metabolism, as well as the biosynthesis and degradation of membrane phospholipids.

Tensor Hypercontraction Error Correction Using Regression
The combination of tensor hypercontraction with machine learning bridges the gap between accuracy and computational efficiency through scaling reduction. ABSTRACT Wavefunction‐based quantum methods are some of the most accurate tools for predicting and analyzing the electronic structure of molecules, in particular for accounting for dynamical electron ...
