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.

Effect of Dispersion Slope of Highly Nonlinear Fibre on The Performance of Self Phase Modulation Based 2R-Optical Regenerator [PDF]

open access: yes, 2010
In this paper we numerically investigate the effect of dispersion slope of the highly nonlinear fibre on the performance of Self Phase Modulation based 2R-optical regenerators.

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.

Sex and Regeneration [PDF]

open access: yesBiology, 2021
Regeneration is usually regarded as a unique plant or some animal species process. In reality, regeneration is a ubiquitous process in all multicellular organisms. It ranges from response to wounding by healing the wounded tissue to whole body neoforming (remaking of the new body).

Analytical Solution of Heat Transfer Performance of Grid Regenerator in Inverse Stirling Cycle

open access: yesEnergies, 2022
The regenerator plays an extremely important role in the Stirling circulation. A grid regenerator can be used for inverse Stirling machines at room temperature due to its low flow resistance.

Numerical Thermal Analysis and 2-D CFD Evaluation Model for An Ideal Cryogenic Regenerator

open access: yesMicromachines, 2020
Regenerative cryocoolers such as Stirling, Gifford–McMahon, and pulse tube cryocoolers possess great merits such as small size, low cost, high reliability, and good cooling capacity.

Field-trial of an all-optical PSK regenerator/multicaster in a 40 Gbit/s, 38 channel DWDM transmission experiment [PDF]

open access: yes, 2012
The performance of future ultra-long haul communication systems exploiting phase-encoded signals is likely to be compromised by noise generated during signal transmission.
