Earth's last magnetic field reversal took far longer than once thought（图）
Earth magnetic field reversal took longer once thought
2019/10/21
Earth's magnetic field seems steady and true -- reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes.The magnetic North Pole is currently shifting tow...
Where Food Is Limited,Guppy Mothers Gestate Their Young Longer（图）
Food Is Limited Guppy Mothers Gestate Young Longer
2017/10/25
Trinidadian guppy mamas can’t swap links to maternity blogs or copies of pregnancy books, yet evolution has made them master strategists of childbearing nonetheless. A new study shows that guppies who...

Accelerates Quest for Quicker Longer-lasting Electronics
2017/7/24
In the world of electronics, where the quest is always for smaller and faster units with infinite battery life, topological insulators (TI) have tantalizing potential.In a paper published today in “Sc...
Is Spring Getting Longer?UNH Research Points to a Lengthening “Vernal Window”
Spring Getting Longer UNH Research Points Vernal Window

With the first day of spring around the corner, temperatures are beginning to rise, ice is melting, and the world around us is starting to blossom. Scientists sometimes refer to this transition from w...
Undernutrition screening survey in 564,063 patients: patients with a positive undernutrition screening score stay in hospital 1.4 d longer
LOS malnutrition undernutrition hospital screening

Background: Undernutrition is a common complication of disease and a major determinant of hospital stay outcome. Dutch hospitals are required to screen for undernutrition on the first day of admission...
THE OCEANOGRAPHY CLASSROOM | Working Away From Home–The Longer-term Option
OCEANOGRAPHY CLASSROOM Working Away Longer-term Option
2015/7/3
In my last missive to this learned publication, I considered the positive benefits of vacation or short-term work experience abroad for undergraduates of ocean and earth science. But what about the mo...
Longer-Baseline Telescopes Using Quantum Repeaters
Longer-Baseline Telescopes Using Quantum Repeaters
2011/10/17
We present an approach to building interferometric telescopes using ideas of quantum information. Current optical interferometers have limited baseline lengths, and thus limited resolution, because of...
The Optical Gravitational Lensing Experiment. Dwarf Novae in the OGLE Data. I. Three New Dwarf Novae: One in the Period Gap and Two Longer Period Objects
novae, cataclysmic variables – binaries: close – surveys
2011/10/8
We report serendipitous discovery of three new dwarf novae which eruptions in 2010 were observed by the ongoing microlensing survey OGLE-IV. All three objects are located in the Galactic bulge fields ...
No Longer Anchored, Antarctic Ice Stream Surges to Sea--Under-Ice Sub Finds Ridge That May Have Held Back Pine Island Glacier（图）
Antarctic Ice Stream Sea Ice Sub Back Pine Island Glacier
2010/6/22
Satellite tracking has shown that the Pine Island Glacier, one of Antarctica's largest ice streams, is accelerating and thus contributing a growing share of the melt water raising sea levels worldwide...
The non-truncated bulk arrival queue M^x/M/1 with reneging, balking, state-dependent and an additional server for longer queues
Non-truncated queue longer queues Balking Reneging concept
2010/9/10
The aim of this paper is to derive the solution of the non-truncated queue: Mx/M/1 with reneging, balking, state-dependent and an additional server for longer queues. In this case the units arrive in ...
Remotely Driven Decadal and Longer Changes in the Coastal Pacific Waters of the Americas
Remotely Driven Decadal Longer Changes Coastal Pacific Waters Americas
2008/7/10
Previous work has shown that near-surface ocean temperature off southern California increased during the 1970s and 1980s. This increase is probably not due to anthropogenic effects since measurements ...
