Scientists studied microorganisms from an underwater mountain in the Atlantic Ocean, pioneering a method that could open new windows into our understanding of how life survives deep under the sea -- o...
Ice cave in Transylvania yields window into region's past
Ice cave Transylvania yields window region past
2017/7/19
Ice cores drilled from a glacier in a cave in Transylvania offer new evidence of how Europe's winter weather and climate patterns fluctuated during the last 10,000 years, known as the Holocene period....
Is Spring Getting Longer?UNH Research Points to a Lengthening “Vernal Window”
Spring Getting Longer UNH Research Points Vernal Window
2017/3/30
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...
Gene network controls how many flowers and fruits plants will produce during critical growth window
Gene network controls flowers and fruits plants critical growth window
2016/11/29
There is staggering diversity in the number of flowers produced by each of the 2,800 or so species of plants in the nightshade family, which includes economically important crops such as tomatoes, pep...
MULTI-WINDOW GABOR FRAMES IN AMALGAM SPACES
Wiener amalgam space Gabor frame Wiener’s Lemma
2015/12/10
We show that multi-window Gabor frames with windows in the Wiener algebra W(L∞, `1) are Banach frames for all Wiener amalgam spaces. As a by-product of our results we prove thecanonical dual of a Gabo...
Intraplate Seamounts as a Window into Deep Earth Processes
Intraplate Seamounts Window Deep Earth Processes
2015/7/7
Seamounts are windows into the deep Earth that are helping to elucidate various deep Earth processes. For example, thermal and mechanical properties of oceanic lithosphere can be determined from the f...

2015/7/7
Knowledge is key to good science and good management. But, what do you do when the information you need is scattered among hundreds of journals and reports, in dozens of languages? Or worse, data are ...
An Application of a Variable Window Discrete Scan Statistic in Molecular Biology
Amino acids Moving sums Product-type approximation Scan statistic
2015/3/18
In this article a variable window discrete scan statistic is introduced for a
conditional scan statistic. This statistic is used to test the null hypothesis that the
observations are randomly distri...
SuperCam: a 64-pixel heterodyne imaging array for the 870-micron atmospheric window (Proceedings Paper)
Heterodyne imaging arrays submillimeter molecular spectroscopy
2014/12/23
We report on the development of SuperCam, a 64 pixel, superheterodyne camera designed for operation in the astrophysically important 870 μm atmospheric window. SuperCam will be used to answer fundamen...
This imaging technology provides unprecedented 3-D views of an intact brain's neural structure and its vast internal connections
The connections between neurons in the brain are involved in everythin...
3-D imaging provides window into living cells, no dye required（图）
3-D imaging living cells
2014/3/18
CHAMPAIGN, Ill. — Living cells are ready for their close-ups, thanks to a new imaging technique that needs no dyes or other chemicals, yet renders high-resolution, three-dimensional, quantitative imag...
Window shifts, flop equivalences and Grassmannian twists
Window shifts flop equivalences Grassmannian twists Algebraic Geometry
2012/6/14
We introduce a new class of autoequivalences that act on the derived categories of certain vector bundles over Grassmannians. These autoequivalences arise from Grassmannian flops: they generalize Seid...
The photographs in this journal are educational and enlightening, explicit and enigmatic, moving and disturbing, beautiful and optimistic. This glimpse into a handful of lives paints a picture of life...
Gaia: a Window to Large Scale Flows
Gaia Window Large Scale Flows redshifts galaxy distances
2012/2/21
Using redshifts as proxy for galaxy distances, estimates of the 2D transverse peculiar velocities of distant galaxies ($cz\ltsim 2\times 10^4 \kms$) can be obtained from Gaia's measurements of proper ...
The metallicity distribution of bulge clump giants in Baade's Window
Galaxy: bulge – Galaxy: formation – Galaxy: abundances – Stars: abundances – Stars: atmosphere
2011/10/20
We seek to constrain the formation of the Galactic bulge by means of analysing the detailed chemical composition of a large sample of red clump stars in Baade's window. We measure [Fe/H] in a sample o...
