Study on optimal safety and low-noise control for weapon launching from underwater vehicles

open access: yesZhongguo Jianchuan Yanjiu
Objective Low-speed launching of weapons from underwater vehicles can greatly reduce radiated noise. However, it may lead to collisions between the weapon leaving the launch tube and the moving vehicle if the launching velocity is too low.

Associations of Rheumatoid Arthritis Disease Activity With Frailty Over Five Years of Follow‐up

open access: yesArthritis Care &Research, EarlyView.
Objective To evaluate whether rheumatoid arthritis (RA) disease activity is associated with frailty both in cross‐section and longitudinally. Methods Participants within the Veterans Affairs Rheumatoid Arthritis (VARA) registry enrolled from 2003 to 2022 were included.

Effect of prestressed loading on low-speed impact performance for carbon fiber/epoxy resin composite laminates

open access: yesAIP Advances
Carbon Fiber Reinforced Polymer (CFRP) laminates habitually experience either tensile or compressive prestressing loads and are simultaneously susceptible to external low-velocity impacts in genuine operating scenarios.

Cracking the Code: Which Ocular Symptoms Predict Dry Eye Signs? Insights From a Large International Sicca Registry

open access: yesArthritis Care &Research, EarlyView.
Objective The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögren's International Collaborative Clinical Alliance (SICCA) cohort. Methods We performed a retrospective analysis examining 16 ocular symptoms (most graded 0–4) and artificial tear (AT) use (graded 0–3) as predictors of DED signs (abnormal ocular ...

Evaluation of Collision Detection and Reaction for a Human-Friendly Robot on Biological Tissues

open access: yes, 2008
Up to now, mostly blunt human-robot impacts were investigated in the robotics literature. In this context, the influence of robot mass and velocity during rigid impacts with and without the possibility of the human being clamped was quantified.

Pain and Patient‐Reported Physical Function Did Not Differ Among Body Composition Profiles in Patients With Hip Osteoarthritis

open access: yesArthritis Care &Research, EarlyView.
Objective To explore whether higher body fat and lower lean mass are associated with greater pain and worse patient‐reported physical function in individuals with hip osteoarthritis (OA). A secondary aim was to examine whether pain and patient‐reported physical function differ according to four body composition profiles: high body fat, low lean mass ...

INVESTIGATION OF THE COMPOSITE BEAM BEHAVIOR SUBJECTED TO IMPACT FATIGUE LOADING

open access: yesJournal of Engineering and Sustainable Development, 2015
The objective of this research is to investigate the effect of repeated low-velocity impacts experimentally on composite materials in which two types of laminated composite beams are used (2D and 3D woven fabric/lamination (80:20) resin) under ...

Obesity Subtypes and Longitudinal Trajectories of Function Over Seven Years of Follow‐Up: Data From the Multicenter Osteoarthritis Study

open access: yesArthritis Care &Research, EarlyView.
Objective Obesity, defined by body mass index (BMI) ≥30 kg/m2, is a risk factor for functional limitations in people with knee osteoarthritis (OA). However, function varies among such individuals. Our objective was to evaluate the implications of obesity subtypes on longitudinal patterns of physical functioning in people with or at risk for knee OA ...

Damage Monitoring in Woven Composites Using Fiber-Bragg Grating Sensors on Multiple Time Scales

open access: yes, 2009
This study investigates the application of Fiber Bragg Grating (FBG) optical sensors interrogation techniques over several time scales to monitor damage in composite structures due to low velocity impacts events.
