Earlier this year, astronomers were keeping tabs on data from the Zwicky Transient Facility, an all-sky survey based at the Palomar Observatory in California, when they detected an extraordinary flash...
Urban development reduces flash flooding chances in the arid West（图）
Urban development flash flooding chances
2019/11/22
Urban development in the eastern United States results in increased flash flooding in nearby streams, but in the arid West, urbanization has the opposite effect, according to NSF-funded research led b...
FLASH FLOOD MAPPING FOR MOUNTAIN STREAMS USING HIGH-RESOLUTION ALOS-2 DATA
ALOS-2 Capacity building Flood detection Valley floodplain
2018/4/18
This paper introduces a practical way to improve the risk management capacity and resilience of communities by utilizing a prompt flash flood map produced from very high spatial resolution ALOS-2 data...
On the Origin of Heme Absorption Band Shifts and Associated Protein Structural Relaxation in Myoglobin Following Flash Photolysis
transhydrogenase NAD NADP Escherichia coli proton pump metal ion
2016/5/23
The role of the protein structural change monitored by absorption band shifts following flash photolysis of CO from myoglobin is discussed in terms of structure-function relationships. Evidence is pre...
Flash sourcing, or rapid detection and characterization of earthquake effects through website traffic analysis
Monitoring Seismic risk Algorithms and implementation
2015/8/27
This study presents the latest developments of an approach called ‘flash sourcing’, which provides information on the effects of an earthquake within minutes of its occurrence. Information is derived ...
Compendium of eigenmodes in third harmonic cavities for FLASH and the XFEL
Compendium of eigenmodes third harmonic cavities FLASH the XFEL
2012/4/19
The resonant modes in the 9cell 3.9GHz bunch shaping cavity designed by FERMILAB in collaboration with DESY [1] and installed in FLASH at DESY were calculated up to the range of 10GHz in terms of the ...
Flash memory is well-known for its inherent asymmetry:the flash-cell charge levels are easy to increase but are hard to decrease.
Evolution and nucleosynthesis of extremely metal-poor and metal-free low- and intermediate-mass stars II. s-process nucleosynthesis during the core He flash
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
Models of primordial and hyper-metal-poor stars with masses similar to the Sun experience an ingestion of protons into the hot core during the core helium flash phase at the end of their red giant bra...
The E8 Lattice and Error Correction in Multi-Level Flash Memory
E8 Lattice Error Correction Multi-Level Flash Memory
2010/12/14
A construction using the E8 lattice and Reed-Solomon codes for error-correction in flash memory is given. Since E8 lattice decoding errors are bursty, a Reed-Solomon code over GF(28) is well suited. T...
In this paper, we develop the theory of flashes of an algebraic curve. We show that the theory is birationally invariant in a sense which we will make more precise below. We also show how the theory p...
Reconstructing the 1874 Santa Tecla flash flood in the Ondara River (Ebro Basin, NE Spain)
Reconstructing the 1874 Santa Tecla flash flood
2010/9/10
The Santa Tecla flash flood, a very heavy event occurred in Tàrrega (Catalonia, NE Iberian Peninsula) in 1874, was reconstructed with hydraulic and hydrological modelling tools. The hydrograph obtaine...
Convenient synthesis of monomeric steroids from steroidal oxalate dimers using flash vacuum pyrolysis (FVP)
Steroid oxalate dimers steroidal alkene diene triene
2010/10/18
Flash vacuum pyrolysis (FVP) or thermolysis (FVT), an environmentally friendly method for studying organic reaction mechanisms as well as synthesis, was applied to a series of oxalate dimers (1, 3, 5,...
