The Anatomical Record, EarlyView.Abstract Intraspecific variation in social organization (IVSO) within primate populations can arise due to male mating competition. Verreaux's sifaka (Propithecus verreauxi) populations exhibit both single‐male and multi‐male groups, providing an opportunity to examine the relationship between male competitive ability and social organization.

Listening to Hong Kong children's perspectives through pretend play
British Educational Research Journal, EarlyView.Abstract Quality in early childhood education and care (ECEC) has become an increasing concern in recent years. The issue has been regularly discussed by different stakeholders. However, the rising concern regarding quality in ECEC has not seriously taken into account children's perspectives.

Sleep during an antarctic overwintering: comparing an altitude base and a coastal station
Sleep Medicine, 2013 IntroductionThe occurrence of sleep disturbances in Antarctic regions is a consistent finding in literature. Indeed, spending winter in Antarctica, exposed to total darkness, has been significantly associated with total hours of sleep, duration of the longest sleep event, time of sleep onset and quality of sleep.

Energy efficiency of joint base station and relay sleeping in heterogeneous networks
IET Communications, 2017 Energy efficiency (EE) is an important criterion in devising emerging mobile networks. One of the techniques that has been proposed to reduce energy consumption of base stations (BSs) in cellular networks is BS sleep mode. In this work, the effect of sleep mode on throughput, coverage and EE of relay assisted heterogeneous cellular networks is analysed.

Cell sleeping for energy efficiency in cellular networks: Is it viable? [PDF]
, 2012 An approach advocated in the recent literature for reducing energy consumption in cellular networks is to put base stations to sleep when traffic loads are low. However, several practical considerations are ignored in these studies. In this paper, we aim

Climate‐related exposures and seizures in children: A systematic review
Epilepsia, EarlyView.Abstract Objective Climate‐related exposures, including air pollution, temperature extremes, humidity, and atmospheric conditions, are increasingly recognized as potential seizure triggers. As climate change intensifies, understanding the environmental contributors to pediatric seizure risk has important implications for anticipatory guidance and ...
