The sealing performance of the rubber packer is vital importance for subsea retractable connector, and cross-sectional shape one most important factors affecting it. compression distance increased by 19.54% utilizing established two-dimensional numerical model. In addition, a new parameter called anti-shoulder extrusion variable was defined in this paper. Shoulder will not occur when using as c...

We present a highly functional and cost-effective prosthesis for transfemoral amputees that uses series elastic actuators. These actuators allow for accurate force control, low impedance and large dynamic range. The design involves one active joint at the knee and a passive joint at the ankle. Additionally, the socket was designed using mirroring of compliances to ensure maximum comfort.

This paper summarizes the results of studies undertaken to investigate revolutionary propulsion-airframe configurations that have the potential to achieve significant noise reductions over present-day commercial transport aircraft. Using a 300 passenger BlendedWing-Body (BWB) as a baseline, several alternative low-noise propulsion-airframeaeroacoustic (PAA) technologies and design concepts were...

The retractable proboscis of acanthocephalans is equipped with hooks for attachment to the intestine definitive host. Throughout their evolutionary history, have developed a variety ways maximize anchoring host gut and avoid dislodgement. Hooks vary in size shape along longitudinal axis proboscis, texture, structure, hardness as well contribution absorption nutrients. also chemical composition,...

chronic granulomatous disease is an infrequent primary immunodeficiency characterized by defective intracellular killing of ingested microorganisms thereby making patients highly susceptible to recurrent lite threatening bacterial and fungal infections. in this study, we review the medical course of an 8 yr old girl with ar-cgd. she suffered from recurrent dermal and deep abscesses, retractable...

Abstract With the spread of COVID-19, significant emphasis has been placed on mitigation techniques such as mask wearing to slow infectious disease transmission. Widespread use face coverings revealed challenges contamination and waste, presenting an opportunity improve current technologies. In response, we have developed Auto-sanitizing Retractable Mask Optimized for Reusability (ARMOR). ARMOR...

Recent evidence has suggested that thalamic amnesia results from damage to the intralaminar nuclei, an important source of input to striatum. To test the hypothesis that intralaminar damage disrupts functions mediated by striatum, we studied the effects of striatal lesions on a delayed matching task known to be affected by intralaminar lesions. Rats were trained to perform the task and given on...

We define an effective, sound and complete game semantics for HAinf, Intuitionistic Arithmetic with ω-rule. Our semantics is equivalent to the original semantics proposed by Lorentzen [6], but it is based on the more recent notions of ”backtracking” ([5], [2]) and of isomorphism between proofs and strategies ([8]). We prove that winning strategies in our game semantics are tree-isomorphic to th...
