On Modulo AG-groupoids [PDF]

arXiv, 2014
A groupoid G is called an AG-groupoid if it satisfies the left invertive law: (ab)c = (cb)a. An AG-group G, is an AG-groupoid with left identity e \in G (that is, ea = a for all a \in G) and for all a \in G there exists a' \in G such that a.a' = a'.a = e.

Cytogerontology since 1881: A reappraisal of August Weismann and a review of modern progress [PDF]

, 1982
Cytogerontology, the science of cellular ageing, originated in 1881 with the prediction by August Weismann that the somatic cells of higher animals have limited division potential.

Improved Age Estimation for Solar-Type Dwarfs Using Activity-Rotation Diagnostics [PDF]

, 2008
While the strong anti-correlation between chromospheric activity and age has led to the common use of the Ca II H & K emission index (R'_HK = L_HK/L_bol) as an empirical age estimator for solar type dwarfs, existing activity-age relations produce implausible ages at both high and low activity levels.

Ageing industries [PDF]

, 2012
This paper uses micro-data from four years of the Labour Force Survey (1995, 2000, 2005 and 2010) to examine the relationship between employment share and age structure across Scottish industries.

Ageing Policies in Slovenia: Before and After "Austerity" [PDF]

, 2017
Similarly, to other European countries, Slovenia is facing ageing of the population. The European Year for Active Ageing and Solidarity between Generations in 2012 and the recent economic crisis have influenced social policy in the area of ageing and ...

Longitudinal Face Modeling via Temporal Deep Restricted Boltzmann Machines [PDF]

, 2016
Modeling the face aging process is a challenging task due to large and non-linear variations present in different stages of face development. This paper presents a deep model approach for face age progression that can efficiently capture the non-linear aging process and automatically synthesize a series of age-progressed faces in various age ranges.

Personalized Age Progression with Aging Dictionary [PDF]

arXiv, 2015
In this paper, we aim to automatically render aging faces in a personalized way. Basically, a set of age-group specific dictionaries are learned, where the dictionary bases corresponding to the same index yet from different dictionaries form a particular aging process pattern cross different age groups, and a linear combination of these patterns ...

Jockey Club Age-Friendly City Project : Action plan : Tuen Mun

, 2017
In response to the global ageing population, the World Health Organization (the “WHO”) devised the concept of “Global Age-friendly Cities” in 2005 to encourage cities all around the world to develop a healthy and comfortable living environment with age ...

Degradation effects in sc-Si PV modules subjected to natural and induced ageing after several years of field operation [PDF]

, 2012
This paper presents ageing effects observed in sc-Si PV modules operating in field conditions for 18 and over 22 years. The effects of both natural ageing processes and induced ageing by external agents, causing partial or total shading of cells for a ...

Ageing makes us dyslexic [PDF]

, 2013
Background: The effects of typical ageing on spoken language are well known: word production is disproportionately affected while syntactic processing is relatively well preserved.
