Study ties poor sleep to reduced memory performance in older adults（图）
poor sleep reduced memory performance older adults
2019/10/23
A new study has found that variability in night-to-night sleep time and reduced sleep quality adversely affect the ability of older adults to recall information about past events.Although further inve...
Effects of climate change likely to be more deadly in poor African settlements（图）
climate change more deadly poor African settlements
2017/11/23
Conditions in crowded urban settlements in Africa make the effects of climate change worse, pushing temperatures to levels dangerous for children and the elderly in those areas, according to a new stu...
Low serum ω-3 and ω-6 polyunsaturated fatty acids and other metabolites are associated with poor linear growth in young children from rural Malawi
arachidonic acid carnitine dehydroepiandrosterone docosahexaenoic acid malnutrition pregnenolone sulfate stunting
2018/11/21
Background: Stunting affects ～25% of children <5 y of age and is associated with impaired cognitive and motor development and increased morbidity and mortality. The pathogenesis of stunting is poorly ...
In urban Baltimore,poor neighborhoods have more mosquitoes（图）
urban Baltimore poor neighborhoods more mosquitoes
2017/7/24
A new study published in the Journal of Medical Entomology reports that in Baltimore, Maryland, neighborhoods with high levels of residential abandonment are hotspots for tiger mosquitoes (Aedes albop...
Coenzyme Q10 prevents hepatic fibrosis, inflammation, and oxidative stress in a male rat model of poor maternal nutrition and accelerated postnatal growth
developmental programming liver disease coenzyme Q low birth weight accelerated postnatal growth
2018/11/28
Background: It is well established that low birth weight and accelerated postnatal growth increase the risk of liver dysfunction in later life. However, molecular mechanisms underlying such developmen...
Rapamycin Rescues the Poor Developmental Capacity of Aged Porcine Oocytes
Reactive Oxygen Species (ROS) Mammalian Target of Rapamycin (mTOR)
2016/5/16
Unfertilized oocytes age inevitably after ovulation, which limits their fertilizable life span and embryonic development. Rapamycin affects mammalian target of rapamycin (mTOR) expression and cytoskel...

Counting the World's Poor: Problems and Possible Solutions。
Hungry horses could be more susceptible to contracting Hendra virus, according to the findings of a preliminary study into the effect of pasture availability on infection rates.
Vibrational Instability of Metal-Poor Low-Mass Main-Sequence Stars
Vibrational Instability Metal-Poor Low-Mass Main-Sequence Stars
2012/2/24
We find that low-degree low-order g-modes become unstable in metal-poor low-mass stars due to the $\varepsilon$-mechanism of the pp-chain. Since the outer convection zone of these stars is limited onl...
GRB 070125 and the environments of spectral-line poor afterglow absorbers
gamma-ray burst: individual: GRB070125
2011/10/11
GRB 070125 is among the most energetic bursts detected and the most extensively observed so far. Nevertheless, unresolved issues are still open in the literature on the physics of the afterglow and on...
A Generalized Poor-Verdu Error Bound for Multihypothesis Testing and the Channel Reliability Function
Hypothesis testing probability of error maximum-a-posteriori and maximum likelihood estimation channel coding
2011/9/14
Abstract: A lower bound on the minimum error probability for multihypothesis testing is established. The bound, which is expressed in terms of the cumulative distribution function of the tilted poster...
An aluminum/calcium-rich, iron-poor, white dwarf star: evidence for an extrasolar planetary lithosphere?
calcium-rich iron-poor evidence extrasolar planetary lithosphere
2011/10/8
The presence of elements heavier than helium in white dwarf atmospheres is often a signpost for the existence of rocky objects that currently or previously orbited these stars. We have measured the ab...
Center-to-Limb Variation of Radio Emissions from Thermal-Rich and Thermal-Poor Solar Flares
acceleration of particles—Sun: fl ares—Sun: magnetic fi elds—Sun:radio radiation—Sun: X-rays, gamma rays
2011/9/30
A statistical analysis of radio flare events was performed by using the event list of Nobeyama Radioheliograph in 1996-2009. We examined center-to-limb variations of 17GHz and 34GHz flux by dividing t...
CoRoT\,102699796, the first metal-poor Herbig Ae pulsator: a hybrid $δ$ Sct-$γ$ Dor variable?
stars: pre-main-sequence – stars: variables: T Tauri, Herbig Ae/Be variables: Scuti stars: fundamental parameters stars: abundances infrared:stars.
2011/9/9
We present the analysis of the time series observations of CoRoT102699796 obtained by the CoRoT satellite that show the presence of five independent oscilla-
tion frequencies in the range 3.6-5 c/d. ...
The Stellar Abundances for Galactic Archaeology (SAGA) Database II - Implications for Mixing and Nucleosynthesis in Extremely Metal-Poor Stars and Chemical Enrichment of the Galaxy
The Stellar Abundances for Galactic Archaeology Database II
2011/1/13
We discuss the characteristics of known extremely metal-poor (EMP) stars in the Galaxy using the Stellar Abundances for Galactic Archaeology (SAGA) database (Suda et al. 2008, PASJ, 60, 1159).The anal...
