Myoelectric Origami‐Based Soft Robotic Knee Exoskeleton to Enhance Sit‐to‐Stand Assistance in Elderly Populations

Advanced Intelligent Systems, EarlyView.
This work presents a lightweight Miura‐origami soft knee exoskeleton powered by vacuum actuation and integrated with a multimodal physiological intent‐recognition system, providing real‐time assistance during sit‐to‐stand movement to reduce muscle effort and improve user comfort.

Deconvolution of the density of states of tip and sample through constant-current tunneling spectroscopy

Beilstein Journal of Nanotechnology, 2011
We introduce a scheme to obtain the deconvolved density of states (DOS) of the tip and sample, from scanning tunneling spectra determined in the constant-current mode (z–V spectroscopy).

The Global Airways in Practice: Long‐term Effects of Mepolizumab With or Without FESS on Type 2 Inflammation in Patients With CRSwNP

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is a type 2 inflammatory disease often associated with asthma. The global airway hypothesis suggests bidirectional inflammatory interactions between upper and lower airways. Mepolizumab, an anti–IL‐5 therapy, treats conditions systemically, while functional endoscopic sinus surgery ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

The Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

A Note on Two-Stage Fuzzy Location Problems Under VaR Criterion With Irregular Fuzzy Variables

IEEE Access, 2020
Recently, Yang et al. (Computers & Industrial Engineering, 131: 157–171, 2019) proposed a solution approach to the two-stage fuzzy location problem under the Value-at-Risk (VaR) criterion, which significantly reduced the computational ...

Analysis and Approximate Replacement of Tool for Trapezoid Spline Shaft

Jixie chuandong, 2022
The trapezoid spline has the characteristics of good guidance and self-centering， and its application range has been extended to the field of low-speed and high-torque transmission. Based on the tooth profile normal line method， the formula of the hob tooth profile of the trapezoid spline shaft is analyzed.

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

The Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Numerical Study of Fourth-Order Volterra Partial Integrodifferential Equation With Weakly Singular Kernel via Subdivision Collocation Approach

Journal of Function Spaces
In the present article, an emerging subdivision-based technique is developed for the numerical solution of linear Volterra partial integrodifferential equations (LVPIDEs) of order four with a weakly singular kernel. To approximate the spatial derivatives,
