Resonant Dative Bonds

open access: yesAngewandte Chemie, EarlyView.
Dative bonds are an integral, albeit underappreciated, part of the theory of chemical bonds. In their resonant form they can bring a surprising stability to a novel family of rings with multiple hyper/hypo‐valent elements. Abstract The dative bond is an often underappreciated entity in the theory of chemical interactions, despite its explanatory and ...

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.

Machine Learning‐Enhanced Clinical Decision Support for Diagnosing Sinusitis With Nasal Endoscopy

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Sinusitis is a prevalent disease for which nasal endoscopy (NE) is an optimal diagnostic modality. However, NE accuracy is limited by inter‐operator variability in landmark identification and localization of mucus that is necessary for sinusitis diagnosis. We sought to develop a novel multi‐class machine learning (ML) framework that

Development, validation, and preliminary phenotypic characterization of a Col6a3 knockout mouse model targeting exon 3

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Deleting Col6a3 exon 3 by CRISPR in mice results in centralized nuclei consistent with a myopathy phenotype mimicking collagen VI‐associated human disease Abstract Background Most mutations in the COL6A3 gene lead to collagen VI‐related myopathies. This is due to a reduced expression or mislocalization of the COL6A3 protein.
