Accelerating Musculoskeletal Robotics Through Parametric Design and 3D‐Printed Flexible Structures

open access: yesAdvanced Intelligent Systems, EarlyView.
Parametric design and flexible 3D printing create muscle‐, tendon‐, ligament‐, and cushion‐like robotic elements from a single thermoplastic polyurethane material. Tuning lattice patterns adjusts regional mechanical properties and enables coordinated multijoint motions in a life‐sized musculoskeletal leg under external suspension, with partial body ...

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Hydraulic function of medullary bundles in a tropical root climber

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Medullary bundles, which are vascular bundles in the pith, have evolved multiple times. However, their functional significance remains poorly understood. Here, we investigated how medullary bundles are involved in the vascular architecture and hydraulic function in a tropical root climber, Adelobotrys scandens (Melastomataceae) to ...

Early Versus Late Recurrence in Olfactory Neuroblastoma: A Multi‐Institutional Analysis of Predictive Risk Factors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory neuroblastoma (ONB) exhibits variable recurrence patterns, with significant late recurrences occurring years after treatment. We investigated cutoff periods to define late recurrence and identified predictors that distinguish patients at risk of late recurrence from those considered cured.

A Conserved Isoleucine Gates the Diffusion of CO and O2 to the Active Site of NiFe CO‐Dehydrogenase

open access: yesAngewandte Chemie, EarlyView.
A combination of protein film electrochemistry and site‐directed mutagenesis shows that isoleucine 563 (numbering of Thermococcus sp. AM4) gates the arrival of both CO and O2 to the active site of the nickel‐iron CO dehydrogenases. Mutations at this position increase the resistance to O2 at the cost of a slower reaction with CO.

Microbial‐Metabolite Signatures Are Associated With Glucocorticoid Responsiveness in Chronic Rhinosinusitis With Nasal Polyps

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) exhibit heterogeneous responses to oral glucocorticoids (GCs), but the biological basis of this variability remains unclear. Objective To identify gut microbiome‒plasma metabolomic signatures associated with GC responsiveness in CRSwNP patients and to compare their ...

Toward a Behavioral Reserve Model in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Neurology, EarlyView.
Objective Behavioral impairment is common in amyotrophic lateral sclerosis (ALS) and strongly affects autonomy, caregiver burden, and outcomes, yet predictors of vulnerability remain unclear. We investigated whether premorbid regulatory traits and socio‐educational exposures are associated with behavioral phenotypes in ALS within a behavioral reserve ...

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.

Wood Sawdust as a Low‐Cost Filler in Whole‐Tire Reclaimed Rubber: Mechanical Characterization and Factory‐Scale Cost Analysis

open access: yesJournal of Applied Polymer Science, EarlyView.
Whole‐tire reclaimed rubber is upgraded with wood sawdust, a carpentry by‐product available at no cost, across loadings from 0 to 20 wt%. At 5 wt%, tensile strength, elongation, hardness, viscosity, and water absorption all stay within commercial specification, and real factory data show an annual production saving near $62,000 with no capital ...
