Accelerating Multiparametric Quantitative MRI Using Self‐Supervised Scan‐Specific Implicit Neural Representation With Model Reinforcement

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2963-2979, May 2026.
ABSTRACT Purpose To develop a self‐supervised scan‐specific deep learning framework for reconstructing accelerated multiparametric quantitative MRI (qMRI). Methods We propose REFINE‐MORE (REference‐Free Implicit NEural representation with MOdel REinforcement), combining an implicit neural representation (INR) architecture with a model reinforcement ...

Combined Flexion, Torsion and Compression Drive Distinct Intervertebral Disc Failure Mechanisms Under Asymmetric, High‐Cycle Loading

JOR SPINE, Volume 9, Issue 1, March 2026.
Using advanced multiaxial bioreactor systems, this study investigated the effects of flexion, torsion, and static compression on whole intervertebral discs. High cycle asymmetric loading resulted in cell death in the nucleus pulposus and structural changes in the annulus fibrosus.

Square Hash: Fast Message Authentication via Optimized Universal Hash Functions [PDF]

, 1999
This paper introduces two new ideas in the construction of fast universal hash functions geared towards the task of message authentication. First, we describe a simple but novel family of universal hash functions that is more efficient than many standard constructions. We compare our hash functions to the MMH family studied by Halevi and Krawczyk [12].

A Digital Phantom for MR Spectroscopy Data Simulation

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1345-1359, March 2026.
ABSTRACT Purpose Simulated data is increasingly valued by researchers for validating MRS processing and analysis algorithms. However, there is no consensus on the optimal approaches for simulation models and parameters. This study introduces a novel MRS digital brain phantom framework, providing a comprehensive and modular foundation for MRS data ...

Hybrid Classical–Quantum Text Search Based on Hashing

Mathematics
The paper considers the problem of finding a given substring in a text. It is known that the complexity of a classical search query in an unordered database is linear in the length of the text and a given substring.

MXene‐Based Conductive Micropatterned Composites Promote Myogenic Differentiation of Muscle Cells

Small Structures, Volume 7, Issue 3, March 2026.
Micropatterned, conductive MXene/PLA blends were developed to address tissue loss by guiding the alignment and promoting the differentiation of C2C12 muscle cells. Micropatterned MXene/PLA blends with pitch of 100 and 150 μm supported C2C12 myoblast alignment, improved cell interactions, and promoted early myogenic differentiation without induction ...

Securing Generative Artificial Intelligence with Parallel Magnetic Tunnel Junction True Randomness

Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.
True random numbers can protect generative artificial intelligence (GAI) models from attacks. A highly parallel, spin‐transfer torque magnetic tunnel junction‐based system is demonstrated that generates high‐quality, energy‐efficient random numbers.

NAD⁺ Reduction in Glutamatergic Neurons Induces Lipid Catabolism and Neuroinflammation in the Brain via SARM1

Advanced Science, Volume 13, Issue 6, 30 January 2026.
NAD⁺ homeostasis maintains neuronal integrity through opposing actions of NMNAT2 and SARM1. Loss of NMNAT2 in glutamatergic neurons reprograms cortical metabolism from glucose to lipid catabolism, depletes lipid stores, and triggers inflammation and neurodegeneration.
