Processing‐Dependent Performance of the LiNiO2 Cathode in Lithium‐Ion Batteries

Batteries &Supercaps, Volume 9, Issue 5, May 2026.
Processing‐dependent effects on the LiNiO2 cathode are investigated, demonstrating how the size of the pCAM particles, the method of mixing the hydroxide precursors, and the exposure to various atmospheres during the sieving process alter the microstructure, defect chemistry, and surface composition, and ultimately affect the cycling performance and ...

Next Generation 7 Tesla Arterial Spin Labeling With Rotated Spiral Acquisition Enables Mesoscale Resolution in 3D Brain Perfusion and Functional MRI

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2702-2717, May 2026.
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; (

Heights of Butterfly Trees

Random Structures &Algorithms, Volume 68, Issue 3, May 2026.
ABSTRACT Binary search trees (BSTs) are fundamental data structures whose performance is largely governed by tree height. We introduce a block model for constructing BSTs by embedding internal BSTs into the nodes of an external BST—a structure motivated by parallel data architectures—corresponding to composite permutations formed via Kronecker or ...

Research on Modeling and Compensation of Generalized Kinematic Error of RCM Manipulators for Minimally Invasive Surgery Robots

Jixie chuandong
There is a safety issue for geometric and non-geometric errors that lead to remote center of motion (RCM) constraint point position errors during the movement of the RCM manipulator.

Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, Volume 97, Issue 5, Page 2672-2692, May 2026.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

Decomposing Shadow Prices Under Climate‐Driven Growth Scenarios: Insights From an Elk Herd Case Study

Natural Resource Modeling, Volume 39, Issue 2, May 2026.
ABSTRACT Natural capital accounting provides a framework for integrating ecological processes with economic valuation, but the mechanics of shadow price formation often remain opaque to resource managers and policymakers. Using the Clarks Fork elk herd in northwestern Wyoming as a case study, we decompose the shadow price of natural capital into its ...
