To regenerate or not to regenerate: Vertebrate model organisms of regeneration‐competency and ‐incompetency [PDF]

open access: yesWound Repair and Regeneration, 2022
AbstractWhy only certain species can regenerate their appendages (e.g. tails and limbs) remains one of the biggest mysteries of nature. Unlike anuran tadpoles and salamanders, humans and other mammals cannot regenerate their limbs, but can only regrow lost digit tips under specific circumstances.

Regeneration inducers in limb regeneration [PDF]

open access: yesDevelopment, Growth & Differentiation, 2015
Limb regeneration ability, which can be observed in amphibians, has been investigated as a representative phenomenon of organ regeneration. Recently, an alternative experimental system called the accessory limb model was developed to investigate early regulation of amphibian limb regeneration.

Simple DQPSK Signal Regenerator Using Electrical Limiting Amplifiers

open access: yesIEEE Photonics Journal, 2015
A simple optoelectronic regenerator for differential quadrature phase-shift keying (QPSK) signals is demonstrated. The regenerator consists of two parallel delay interferometers followed by balanced detectors, limiting and driving amplifiers, and a dual ...

Optimization of regenerator operating parameters and thermal insulation construction for rotary regenerative thermal oxidizer (r-RTO) based on thermal-fluid coupling method and quadratic regression model

open access: yesCase Studies in Thermal Engineering, 2022
Rotary regenerative oxidiser (r-RTO), an effective VOCs treatment equipment, needs to be operated for a long time under actual working conditions, resulting in excessive temperatures on the outer wall of the r-RTO furnace, which causes production ...
