A Novel Contact‐Implicit Trajectory Optimization Framework for Quadruped Locomotion without Fixed Contact Sequences

open access: yesAdvanced Intelligent Systems, EarlyView.
Legged robots have advanced in environmental interaction through contact, but most works rely on fixed contact sequences. This work presents a new method based on an indirect optimization method for legged robots to automatically generate contact sequences for complex movements.

Planning and Control Framework for a Quadruped Robot With Changeable Configuration

open access: yesAdvanced Intelligent Systems, EarlyView.
Multiconfiguration quadruped robots enhance adaptability by switching between mammal‐like and reptile‐like morphologies. This study presents a nonlinear constraint‐based motion planner integrated with a hierarchical whole‐body controller, enabling robust configuration switching and locomotion on complex terrains. Experiments on slopes, irregular bricks,

A Soft Wearable Robot for Vertical Jump Enhancement via a Pneumatic Energy‐Storing Propulsion Actuator and Triarticular Kinetic‐Chained Structure

open access: yesAdvanced Intelligent Systems, EarlyView.
The Jump‐Enhancing Textile Suit integrates the Pneumatic Energy‐Storing Propulsion Actuator (PESPA) and the Triarticular Kinetic‐Chained Structure (TKiCS). PESPA stores elastic energy under pneumatic pressure and releases it during the propulsive phase to augment movement.

Case Series of Nizon‐Isidor Syndrome by Heterozygous Variants in MED12L With Further Evidence of Mitotic Instability in One Case With Diploid–Triploid Mosaicism

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nizon‐Isidor syndrome is a rare disorder caused by heterozygous variants in MED12L, with only eight documented cases in the literature. Here, we present three additional cases of this syndrome. Proband 1 was a 7‐year‐old female who presented with developmental delay, right‐leg hemihypertrophy, laryngeal cleft, esotropia, abnormal skin ...

Basal Metabolic Requirements, Biomarkers of Cardiometabolic Health, and Anthropometric Measures of Obesity in Women and Men With Restricted Growth Conditions

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Population‐specific thresholds have not been defined for the levels of adiposity and systemic biomarkers that predict chronic health risks in people with restricted growth conditions. Here, anthropometric measures of adiposity, basal metabolic requirements, and fasted blood samples were obtained from adults with restricted growth (age 41 ± 14 ...

Sacroiliac Joint Involvement: An Underreported Complication of NF1

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT NF1‐related bone dysplasia in children and young adults with neurofibromatosis type 1 (NF1) involving the sacroiliac joint has been rarely described. We report four participants who underwent whole‐body magnetic resonance imaging (WB‐MRI) as part of a longitudinal imaging and plexiform neurofibroma (PN) biomarker study (NCT05238909) at Ann ...
