Design and Mechanics of Cable-Driven Rolling Diaphragm Transmission for High-Transparency Robotic Motion [PDF]

arXiv, 2023
Applications of rolling diaphragm transmissions for medical and teleoperated robotics are of great interest, due to the low friction of rolling diaphragms combined with the power density and stiffness of hydraulic transmissions. However, the stiffness-enabling pressure preloads can form a tradeoff against bearing loading in some rolling diaphragm ...

A prospective randomized controlled study on the role of restoring liver diaphragm surface tension and pain control at port sites in optimizing pain management following laparoscopic cholecystectomy

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 131-137, January 2023., 2023
The cornerstone of treatment for symptomatic gallbladder stones is laparoscopic cholecystectomy. Pain is the commonest cause of extended hospital stay. Disturbance of liver—diaphragm surface tension is the main cause of pain. Retained CO2 is a major concern post laparoscopic cholecystectomy.

Topological charge of optical vortices and their superpositions [PDF]

Компьютерная оптика, 2020
An optical vortex passed through an arbitrary aperture (with the vortex center found within the aperture) or shifted from the optical axis of an arbitrary axisymmetric carrier beam is shown to conserve the integer topological charge (TC).

Flow physics of planar bistable fluidic oscillator with backflow limbs

AIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract Fluidic oscillators (FOs) are used in a variety of applications, including process control and process intensification. Despite the simple design and operation of FOs, the fluid dynamics of FOs exhibit rich complexities. The inherently unstable flow, jet oscillations, and resulting vortices influence mixing and other transport processes.

Diaphragm sniff ultrasound: Normal values, relationship with sniff nasal pressure and accuracy for predicting respiratory involvement in patients with neuromuscular disorders.

PLoS ONE, 2019
BackgroundIn patients with neuromuscular disorders, assessment of respiratory function relies on forced vital capacity (FVC) measurements. Providing complementary respiratory outcomes may be useful for clinical trials.

Evaluation of daily residual pancreatic tumor motion for deep‐inspiration breath‐hold radiotherapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Breath‐hold techniques are widely used in radiation therapy to minimize respiratory‐induced tumor or organ‐at‐risk motion. However, residual motion persists, necessitating a reliable daily evaluation method. Methods At our institution, fiducial markers serve as surrogates for target localization in pancreatic cancer treatment.

Demonstrating the Use of a Fungal Synthesized Quinone in a Redox Flow Battery

Batteries &Supercaps, Volume 6, Issue 1, January 2023., 2023
Biobased: The filamentous fungus can be used as an environmentally and sustainable benign source to produce the bio‐based quinone phoenicin. This natural compound shows electrochemical properties, which can be used as the active material in the negative electrolyte in a redox flow battery with results showing that biologically produced quinones may ...
