Via‐Points Task Execution Based on Enhanced Dynamic Movement Primitives and Steering Force Fields

Advanced Intelligent Systems, EarlyView.
Enhanced dynamic movement primitives with steering force fields enable robotic arms to flexibly traverse static and dynamic via‐points while preserving demonstrated trajectory shapes. The method ensures stability, minimizes free‐space loss, and adapts to complex environments without additional learning, making it particularly suitable for industrial ...

A Review of Trans‐Dimensional Kirigami: From Compliant Mechanism to Multifunctional Robot

Advanced Intelligent Systems, EarlyView.
This review outlines recent advancements in the geometric design and mechanical properties of kirigami. The kirigami is classified into two categories from a compliant mechanism perspective, highlighting their applications in metamaterials and robotic systems. Finally, the future research directions, is explored focusing on the potential of integrating

Degeneracy Sensing Light Detection and Ranging‐Inertial Simultaneous Localization and Mapping with Dual‐Layer Resistant Odometry and Scan‐Context Loop‐Closure Detection Backend in Diverse Environments

Advanced Intelligent Systems, EarlyView.
This paper presents a degeneracy‐aware light detection and ranging (LiDAR)‐inertial framework that enhances LiDAR simultaneous localization and mapping performance in challenging environments. The proposed system integrates a dual‐layer robust odometry frontend with a Scan‐Context‐based loop‐closure detection backend.

Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review

Advanced Intelligent Systems, EarlyView.
This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.

Amyotrophic Lateral Sclerosis and Frontotemporal Dementia Have Distinct Prediagnostic Blood Biochemical Profiles

Annals of Neurology, EarlyView.
Objective Identifying modifiable factors influencing amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) risk is important for prevention. Blood biomarkers, particularly cholesterol, have been associated with neurodegenerative risk, but findings in ALS are inconsistent, and data on FTD are limited.

Brain Atrophy Associated With Risk Variant rs10191329 Extends Beyond Multiple Sclerosis

Annals of Neurology, EarlyView.
The risk allele rs10191329*A is associated with disease severity and brain atrophy in people with multiple sclerosis (MS). We investigated the association of rs10191329 with age‐related brain atrophy in a population‐based cohort using 10,308 magnetic resonance imaging (MRI) scans of 4,815 participants aged ≥ 45 years without MS in cross‐sectional and ...

Exergy and Economic Analysis of Hybrid Mechanical Vapor Compression and Membrane Distillation

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Hybridization of two or more desalination processes has been identified as an attractive option for improved energy efficiency and recovery rate. To appropriately assess the performance enhancement of hybrid desalination systems, an integrated approach for energy, exergy, economic, and environmental investigations should be adopted. This study

The relationship between form and function of the carnivore mandible

The Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...
