Machine learning model for fast prediction and uncertainty quantification of needle deflection during prostate biopsy. [PDF]

Med Phys
Abstract Background Accurate needle placement is essential for prostate biopsy. Recently, transperineal prostate biopsies are receiving renewed interest due to concern over infection from conventional transrectal biopsies. However, accurate needle placement is more challenging in the transperineal approach than in the transrectal approach due to the ...

Feasibility of video-based skill assessment for percutaneous nephrostomy training in Senegal. [PDF]

Healthc Technol Lett
With limited access to dialysis and transplantation in sub‐Saharan Africa, training for life‐saving procedures like percutaneous nephrostomy is essential to prevent renal damage from obstructive disease. In this study, we used a trained object detection network to compute motion‐based metrics in order to assess differences in ultrasound and needle ...

Optimization of thermal degradation performance of plasticized poly(vinyl chloride)‐boron composite films using response surface methodology

Journal of Applied Polymer Science, Volume 140, Issue 40, Page 1-18, October 20, 2023., 2023
Experimental plan of this study. Abstract This work aims to statistically assess the dehydrochlorination of plasticized poly(vinyl chloride) (p‐PVC) films produced using boron waste sludge, heat stabilizer mixture (Ca‐ZnSt2), and plasticizer (dioctyl terephthalate). This study also focuses on providing information about the effect of boron waste sludge

CO2‐mediated bloater defect can be induced by the uncontrolled growth of Enterobacteriaceae in cucumber fermentation

Food Science &Nutrition, Volume 11, Issue 10, Page 6178-6187, October 2023., 2023
The carbon dioxide formed by Enterobacteriaceae in cucumber fermentation is trapped in the fruits causing bloater defect. Understanding that Enterobacteriaceae can cause bloater defect propels the development of strategies to prevent economic losses for processors.

Modification of gelatin and photocured 3D‐printed resin to prepare biomimetic phantoms for ultrasound‐guided minimally invasive surgeries

Polymer Engineering &Science, Volume 63, Issue 2, Page 413-425, February 2023., 2023
3D‐printed photo‐resin phantoms were developed for hard and soft tissues. The additives of crosslinkers, nanoparticles, and reactive monomers improved the mechanical strength, acoustic properties, needle insertion forces, and antiseptic periods of phantoms efficiently.

Development of Flexible Composite Sheet with Chrome Shavings Using Polyvinyl Alcohol as a Cross‐Linker

International Journal of Polymer Science, Volume 2023, Issue 1, 2023., 2023
Leather processing generates a huge amount of chromium (Cr) containing wastes, and one of them is chrome shavings (CS), which frequently end up in landfills. It may be harmful to the environment and human health due to the oxidation of Cr(III) to poisonous Cr(VI).

Stiffness Graded Electroactive Artificial Muscle

Advanced Functional Materials, Volume 32, Issue 39, September 26, 2022., 2022
An electroactive artificial muscle material with smooth graded stiffness enables programmable stiffness variation from hard material for loading and anchoring to soft material for actuation. This monolithic structure is introduced by programming the diffusion of a rigid filler material (polyvinyl chloride) in a liquid plasticizer (diisodecyl adipate ...

Structure‐Performance Guided Design of Sustainable Plasticizers from Biorenewable Feedstocks

European Journal of Organic Chemistry, Volume 2021, Issue 45, Page 6086-6096, December 7, 2021., 2021
Addressing the challenge of switching the raw material basis in plastics production from fossil to bio‐based feedstocks, the synthesis of bicyclic plasticizers, which are accessible from the biorenewable compounds 2‐methylfuran, maleic anhydride and 2‐ethylhexanol, is presented as well as their use in performance tests.
