Points of Concern [PDF]

open access: yes, 2000
This is a critical review of Raymond Martin's 'Self-Concern' (1998), focusing especially on his criticism of Parfit's use of fission thought-experiments and his own 'fission rejuvenation' thought ...

Rejuvenating Tithonus [PDF]

open access: yesEMBO reports, 2013
Four recent publications, including one in this issue by Surani and colleagues, report that Prdm14 preserves the pluripotent stem cell state by inhibiting FGF signalling and global DNA methylation.

Semi-independent resampling for particle filtering [PDF]

open access: yes, 2017
Among Sequential Monte Carlo (SMC) methods,Sampling Importance Resampling (SIR) algorithms are based on Importance Sampling (IS) and on some resampling-based)rejuvenation algorithm which aims at fighting against weight degeneracy.

Skeletal muscle as an experimental model of choice to study tissue aging and rejuvenation. [PDF]

open access: yes, 2020
Skeletal muscle is among the most age-sensitive tissues in mammal organisms. Significant changes in its resident stem cells (i.e., satellite cells, SCs), differentiated cells (i.e., myofibers), and extracellular matrix cause a decline in tissue ...

Tet2 Rescues Age-Related Regenerative Decline and Enhances Cognitive Function in the Adult Mouse Brain. [PDF]

open access: yes, 2018
Restoring adult stem cell function provides an exciting approach for rejuvenating the aging brain. However, molecular mechanisms mediating neurogenic rejuvenation remain elusive.

Rejuvenation by cell reprogramming: A new horizon in gerontology [PDF]

open access: yes, 2018
The discovery of animal cloning and subsequent development of cell reprogramming technology were quantum leaps as they led to the achievement of rejuvenation by cell reprogramming and the emerging view that aging is a reversible epigenetic process. Here,

Rejuvenation and Memory in model Spin Glasses in 3 and 4 dimensions

open access: yes, 2005
We numerically study aging for the Edwards-Anderson Model in 3 and 4 dimensions using different temperature-change protocols. In D=3, time scales a thousand times larger than in previous work are reached with the SUE machine.

Aging after shear rejuvenation in a soft glassy colloidal suspension: evidence for two different regimes

open access: yes, 2006
The aging dynamics after shear rejuvenation in a glassy, charged clay suspension have been investigated through dynamic light scattering (DLS). Two different aging regimes are observed: one is attained if the sample is rejuvenated before its gelation and

Software Aging Analysis of Web Server Using Neural Networks

open access: yes, 2012
Software aging is a phenomenon that refers to progressive performance degradation or transient failures or even crashes in long running software systems such as web servers.

Aging, rejuvenation and thixotropy in complex fluids. Time-dependence of the viscosity at rest and under constant shear rate or shear stress [PDF]

open access: yes, 2008
Complex fluids exhibit time-dependent changes in viscosity that have been ascribed to both thixotropy and aging. However, there is no consensus for which phenomenon is the origin of which changes.
