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 ...

A Modular Nucleoside Kinase Cascade for the Synthesis of Ribonucleoside Triphosphates

Biotechnology and Bioengineering, Volume 123, Issue 8, Page 2180-2191, August 2026.
Damm et al. report standardized enzymatic cascades for production of all canonical nucleoside triphosphates from the corresponding nucleosides, using kinase‐catalyzed phosphorylation from acetyl phosphate. Reactions afforded ∼ 100 mM product in near‐quantitative conversion.

A theoretical model for evaluating the impact of connected and autonomous vehicles on the operational performance of turbo roundabouts

International Journal of Transportation Science and Technology
This article presents a methodology to estimate the entry capacity (EC) and total capacity (TC) of basic turbo roundabouts under partial and fully connected and autonomous vehicle (CAV) environments. EC calculations are partially based on capacity models

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

International Journal of Chemical Kinetics, Volume 58, Issue 7, Page 371-382, July 2026.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures

Hierarchically Porous Coatings for Cellulose Fibers by Core–Shell Particle Templating

Macromolecular Rapid Communications, Volume 47, Issue 13, 3 July 2026.
Hybrid and functional core–shell particles comprising a silica core and a polymer shell were synthesized and used to develop a coating and etching process applied to a cellulose substrate. This resulted in highly porous, functional coatings on a cellulose membrane for further application in cellulose‐based adsorbers and advanced membrane technology ...

Dipolar Order Mapping Based on Spin‐Lock Magnetic Resonance Imaging

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
To quantify the dipolar order relaxation time T1D$$ {T}_{1D} $$ using spin‐lock MRI technique, we introduce a T1D$$ {T}_{1D} $$‐specific ratio, denoted as RATIOdosl$$ {RATIO}_{dosl} $$. A novel rotary‐echo spin‐lock sequence was developed to enable dual‐frequency spin‐lock acquisition.

Optimization of Traffic at Uncontrolled Intersections: Comparison of the Effectiveness of Roundabouts, Signal-Controlled Intersections, and Turbo-Roundabouts

Urban Science
This study focuses on optimizing traffic flow at uncontrolled intersections by comparing the effectiveness of different intersection types: roundabouts, signal-controlled intersections, and turbo-roundabouts. The purpose is to determine which type offers

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

Brain Pathology, Volume 36, Issue 4, July 2026.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...

Performance Analysis of Basic Turbo-Roundabouts in Urban Context

Procedia - Social and Behavioral Sciences, 2012
AbstractA turbo roundabout is a new type of canalized multilane intersection in which the physical separation between lanes helps to prevent side collisions when crossing the roundabout. This paper presents an estimation of capacity, delays and level of service of basic turbo roundabouts in undersaturation conditions, considering both vehicle flow and ...
