Social bacteria build shelters using the physics of fingerprints（图）
Social bacteria shelters using physics of fingerprints
2020/12/18
Forest-dwelling bacteria known for forming slimy swarms that prey on other microbes can also cooperate to construct mushroom-like survival shelters known as fruiting bodies when food is scarce.Now, a ...

Engineers at Duke University and New York University have demonstrated a method for ensuring that an increasingly popular method of genetic identification called DNA fingerprinting remains s...
UMD-led Study Finds Ancient Earth’s Fingerprints in Young Volcanic Rocks
UMD-led Ancient Earth’s Fingerprints Young Volcanic Rocks
2017/4/27
Earth’s mantle is made of solid rock that nonetheless circulates slowly over millions of years. Some geologists assume that this slow circulation would have wiped away any geochemical traces of Earth’...
Preface: Evolution of the early solar system: Presolar cosmochemical fingerprints and the formation of watery rocky planets
Presolar cosmochemical fingerprints the formation of watery rocky planets
2017/4/10
Recent developments in cosmochemistry of high-precision
and high spatial resolution isotope analyses, and of
high-performance computing techniques, have enabled
cosmochemists to gain vital insight ...
New mathematical theory may explain patterns in fingerprints, raisins, and microlenses
mathematical theory patterns in fingerprints raisins microlenses
2015/3/4
As a grape slowly dries and shrivels, its surface creases, ultimately taking on the wrinkled form of a raisin. Similar patterns can be found on the surfaces of other dried materials, as well as in hum...
We introduce a new type of cryptographic primitive that we call hiding fingerprinting. A (quantum) fingerprinting scheme translates a binary string of length $n$ to $d$ (qu)bits, typically $d\ll n$, s...
Extreme events in total ozone over Arosa – Part 2: Fingerprints of atmospheric dynamics and chemistry and effects on mean values and long-term changes
Extreme events total ozone Arosa atmospheric dynamics and chemistry and effects mean values long-term changes
2010/11/3
In this study the frequency of days with extreme low (termed ELOs) and extreme high (termed EHOs) total ozone values and their influence on mean values and trends are analyzed for the world's longest ...
Variogram maps from LiDAR data as fingerprints of surface morphology on scree slopes
Variogram maps LiDAR data fingerprints surface morphology scree slopes
2009/12/16
Herein, an aerial LiDAR topographic dataset is analysed and interpolated by means of geostatistical techniques in order to examine the morphology of a scree slope area in the Eastern Italian Alps. The...

2007/3/2
28 February 2007，The AFM – invented some 20 years ago – is the best eye scientists have for examining atoms on the surfaces of both insulators and conductors. In the most refined "dynamic" mode a tiny...
Spatial and temporal variation in trace elemental fingerprints of mytilid mussel shells: A precursor to invertebrate larval tracking
Spatial and temporal variation trace elemental fingerprints mytilus mussel shells invertebrate larval tracking
2014/5/8
Elements incorporated into developing hard parts of planktonic larvae record the environmental conditions experienced during growth. These chemical signatures, termed elemental fingerprints, potential...
Fingerprints of biocomplexity: Taxon-specific growth of phytoplankton in relation to environmental factors
biocomplexity Taxon-specifi c
2014/5/16
Phytoplankton and environmental conditions in Lake Washington, Seattle, Washington, are discussed from the
perspective of dynamic relationships between taxon-specific growth rates and environme...
