Cognitive function in childhood and lifetime cognitive change in relation to mental wellbeing in four cohorts of older people [PDF]

, 2012
Background: poorer cognitive ability in youth is a risk factor for later mental health problems but it is largely unknown whether cognitive ability, in youth or in later life, is predictive of mental wellbeing.

Forecasting Photovoltaic Module Remaining Life-Time Using Accelerated Aging Testing and Modelling on Aged Modules

SiliconPV Conference Proceedings
This work investigates the possibility of predicting the remaining lifetime of a power plant by making accelerated aging testing on monocrystalline silicon cells modules working on a photovoltaic plant for eleven years in France and compares the results with the same testing done on modules from the same batch eleven years ago when they were new.

Cognitive abilities and portfolio choice [PDF]

, 2008
We study the relation between cognitive abilities and stockholding using the recent Survey of Health, Ageing and Retirement in Europe (SHARE), which has detailed data on wealth and portfolio composition of individuals aged 50+ in 11 European countries ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Accelerated aging and life tests of optical fibers

, 2000
The reliability of the network optical fibers is a critical issue for telecommunications.New investigations methods have been developed within a cooperative program supported by France Telecom. They include low coherence interferometry and optical near field microscopy in association with classical analysis tools such as Scanning Electron Microscopy ...

Effects of spermidine supplementation on cognition and biomarkers in older adults with subjective cognitive decline (SmartAge)—study protocol for a randomized controlled trial [PDF]

, 2019
Background: Given the global increase in the aging population and age-related diseases, the promotion of healthy aging is one of the most crucial public health issues.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Flight experience and executive functions predict unlike professional pilots who are limited by the FAA's age rule, no age limit is defined in general aviation (GA) [PDF]

, 2010
Unlike professional pilots who are limited by the FAA's age rule, no age limit is defined in general aviation (GA). Some studies revealed significant aging issues on accident rates but these results are criticized.

Ceaseless Toil? Health and Labor Supply of the Elderly in Rural China [PDF]

, 2003
Deborah Davis-Friedmann (1991) described the “retirement” pattern of the Chinese elderly in the prereform era as “ceaseless toil”: lacking sufficient means of support, the elderly had to work their entire lives.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
