Intra‐MRI Head Motion Tracking and Correction: A Quantitative In Vivo Evaluation Framework

NMR in Biomedicine, Volume 39, Issue 9, September 2026.
This framework introduces, for the first time, an in vivo quantification of intra‐MRI head tracking accuracy and precision. By comparing a markerless optical system (MOS) and fat‐signal navigators (FatNav) against a rigid registration‐based reference standard, it successfully detects subtle, axis‐specific performance differences and strengths between ...

Waste Adsorbent Valorization of Biopolymer‐Modified Zn–Fe Layered Double Hydroxides for Crystal Violet Removal and Enhanced Nonenzymatic Urea Detection

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
This graphical abstract illustrates the synthesis of Zn–Fe LDH composites with biopolymers (chitosan, cellulose, and carrageenan) for the efficient removal of crystal violet dye. The resulting spent adsorbents are subsequently repurposed for electrocatalytic urea detection, demonstrating a sustainable, circular approach to wastewater treatment and ...

Surface‐guided analysis of breast shape changes during postoperative radiotherapy by using a functional map framework

Medical Physics, Volume 53, Issue 7, July 2026.
Abstract BackgroundWhile positioning errors during radiotherapy are increasingly well‐characterized and accounted for in the Planning Target Volume (PTV), little is known about the shape and volume changes of the breast in the course of radiotherapy. Yet they represent an unknown factor that may impact treatment effectiveness, highlighting the need to ...

Improved Myocardial Sodium Quantification at 7 T Using Interleaved 23Na/1H pTx MRI With Motion and Anatomy‐Based B1 Correction

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 173-190, July 2026.
ABSTRACT Purpose To improve accuracy and repeatability of myocardial 23Na quantification in cardiac MRI at 7 T by combining retrospective respiratory and cardiac motion correction with a novel anatomy‐based B1 bias field correction. Methods In this study, a dual‐nuclear interleaved 23Na/1H MRI sequence at 7 T was applied.

Three‐Dimensional Object Perception Can Emerge From Predictive Learning

Developmental Science, Volume 29, Issue 4, July 2026.
ABSTRACT How do infants develop the ability to perceive objects in a 3D world? The theory of core knowledge suggests infants employ a few principles, such as cohesion, continuity, rigidity, and contact, to guide inference of objects. However, it is challenging to answer how object perception can be learned with similar constraints faced by infants and ...

Sinogram‐based flow estimation in computed tomography using a physics‐informed neural network: Impact of gantry rotation speed, X‐ray fluence and pulsed acquisition on accuracy

Medical Physics, Volume 53, Issue 6, June 2026.
Abstract Background Non‐invasive imaging‐based assessment of blood flow plays a critical role in evaluating heart function and structure. Computed Tomography (CT) is a widely‐used imaging modality that can robustly evaluate cardiovascular anatomy and function, but direct methods to estimate blood flow velocity from movies of contrast dynamics have not ...

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 204-223, June 2026.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.
