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...
Basal roughness of the Institute and Möller Ice Streams, West Antarctica: Process determination and landscape interpretation
Antarctica Roughness Radio-echo sounding Ice dynamics Mö ller Ice Stream Institute Ice Stream
font style='font-size:12px;'>
2014/5/20
We present a detailed analysis of bed roughness beneath Institute and Möller Ice Streams, west Antarctica, using radio-echo sounding data (RES) acquired in the austral summer of 2010/11. We asses...
Influence of bed patchiness, slope, grain hiding, and form drag on gravel mobilization in very steep streams
Influence of bed patchiness slope grain hiding form drag on gravel mobilization very steep streams

Steep streams are a major portion of channel networks and provide a link to transport sediment from hillslopes to lower gradient rivers. Despite their importance, key unknowns remain, perhaps foremost...
Authentication of Digital Streams
Adversarial network list recoverable codes polynomial reconstruction problem stream authentication

2012/12/4
We study the multicast stream authentication problem when the communication channel is under control of an opponent who can drop, reorder and inject data packets. Recently, many coding theory based pr...
Linearized flavor-stability analysis of dense neutrino streams
Linearized flavor-stability analysis dense neutrino streams
font style='font-size:12px;'>
2011/10/18
Neutrino-neutrino interactions in dense neutrino streams, like those emitted by a core-collapse supernova, can lead to self-induced neutrino flavor conversions. While this is a nonlinear phenomenon, t...
Black Hole growth and AGN obscuration by instability-driven inflows in high-redshift disk galaxies fed by cold streams
instability-driven inflows high-redshift disk galaxies cold streams
font style='font-size:12px;'>
2011/9/29
Disk galaxies at high redshift have been predicted to maintain high gas surface densities due to continuous feeding by intense cold streams leading to violent gravitational instability, transient feat...
The Small Covering Factor of Cold Accretion Streams

font style='font-size:12px;'>
2010/11/11
Theoretical models of galaxy formation predict that galaxies acquire most of their baryons via cold mode accretion. Observations of high-redshift galaxies, while nding strong evidence for ubiquitous ...
Quantum Rabi Oscillation of Trapped Ion Driven by Coherent Pulse Streams
Quantum Rabi Oscillation Trapped Ion Driven Coherent Pulse Streams
font style='font-size:12px;'>
2010/11/9
Quantum Rabi oscillations driven by a pulse stream are basic operations in Cirac-Zoller scheme of quantum computation. We investigate the failure probability and population inversion of quantum Rabi ...
On the dynamics of tidal streams in the Milky Way galaxy
Galaxy Astrophysics (astro-ph.GA)
font style='font-size:12px;'>
2011/1/6
We present a brief history of Galactic astrophysics, and explain the origin of halo substructure in the Galaxy. We motivate our study of tidal streams by highlighting the tight constraints that analys...
Carbon cycling within epilithic biofilm communities across a nutrient gradient of headwater streams
Carbon cycling within epilithic biofilm communities across a nutrient gradient headwater streams
font style='font-size:12px;'>
2014/4/17
Primary production (PP), nutrient uptake, and carbon (C) cycling within epilithic biofilm communities were assessed in four headwater streams in the Arkansas Ozarks, U.S.A., representing a hundred-fol...
Effects of seasonality and resource limitation on organic matter turnover by Chironomidae (Diptera) in southern Appalachian headwater streams
seasonality resource limitation Chironomidae in southern Appalachian headwater streams
font style='font-size:12px;'>
2014/4/17
Despite their high abundance, secondary production, and known reliance on detrital material, the role of chironomids (Diptera) in fine particulate organic matter (FPOM) dynamics has not been well quan...
Estimating basal properties of ice streams from surface measurements:a non-linear Bayesian inverse approach applied to synthetic data
basal properties ice streams surface measurements non-linear Bayesian inverse approach
font style='font-size:12px;'>
2010/2/4
We propose a new approach to indirectly estimate basal properties of ice streams, i.e. bedrock topography and basal slipperiness, from observations of surface topography and surface velocities. We dem...
Changes in the Lake Ladik fish community (1972-2004) and ichthyofauna of its inlet and outlet streams (Samsun, Turkey)
Lake Tersakan Stream fish fauna

2009/10/29
The longitudinal current sorting of graded sediment is analysed by use of a
sediment transport formula developed recently by Engelund and Fredsae
(1976). The analysis yields that for a given longitu...
