Wave Glider Surfs Across Stormy Drake Passage In Antarctica（图）
wave glider surfs stormy drake passage antarctica
2017/10/24
The Southern Ocean is key to Earth’s climate, but the same gusting winds, big waves and strong currents that are important to ocean physics make it perilous for oceanographers.Instead their job is inc...
Exploration of the Windward Passage and Jamaica Channel: Tectonic Gateways to the Caribbean Sea
Windward Passage Jamaica Channel
2015/8/10
In August 2014, E/V Nautilus explored the region delimited
by two deep straits of the northern Caribbean: the Windward
Passage, which separates Cuba and Haiti, and the Jamaica
Channel, which sep...
Cdrake: dynamics and transport of the Antarctic circumpolar current in drake passage
Antarctic circumpolar current dynamics and transport
2015/7/15
The Southern Ocean is especially sensitive to climate change, responding to
winds that have increased over the past 30 years (Thompson and Solomon,
2002) and warming at about one degree per centur...
High-Resolution Underway Upper Ocean and Surface Atmospheric Observations in Drake Passage: Synergistic Measurements for Climate Science
Ocean Surface Atmospheric Observations
2015/7/15
This article highlights recent and ongoing studies that analyze in situ underway upper ocean and surface atmospheric observations from frequently repeated transects by the Antarctic Research and Suppl...
On June 22-24, 2015, the 5th Fish Passage Conference will be held for the first time in Europe, in the city of Groningen, The Netherlands. Hundreds of researchers, educators, practitioners, funders an...
This Technical Report was assembled for, and disturbed during, the U.S. Fish and Wildlife Service (USFWS) Fish Passage Workshop (Workshop) held in Hadley, Massachusetts on August 5 and 6, 2014. The Wo...
Effects of Serial Passage on the Characteristics and Chondrogenic Differentiation of Canine Umbilical Cord Matrix Derived Mesenchymal Stem Cells
Mesenchymal Stem Cell Umbilical Cord Matrix Canine Multipotent Differentiation
2016/5/11
Mesenchymal stem cells (MSCs) are often known to have a therapeutic potential in the cell-mediated repair for fatal or incurable diseases. In this study, canine umbilical cord MSCs (cUC-MSCs) were iso...
First Passage Times for a Tracer Particle in Single File Diffusion and Fractional Brownian Motion
First Passage Times Tracer Particle Single File Diffusion Fractional Brownian Motion Biological Physics
2012/5/29
We investigate the full functional form of the first passage time density (FPTD) of a tracer particle in a single-file diffusion (SFD) system whose population is: (i) homogeneous, i.e., all particles ...
Microtubules Interacting with a Boundary: Mean Length and Mean First-Passage Times
Microtubules Boundary Mean Length Mean First-Passage Times Subcellular Processes
2012/5/2
We formulate a dynamical model for microtubules interacting with a catastrophe-inducing boundary. In this model microtubules are either waiting to be nucleated, actively growing or shrinking, or stall...
Asymptotic behaviour of first passage time distributions for Levy processes
Levy processes first passage time distribution local limit theorems fluctuation theory
2011/9/19
Abstract: Let $X$ be a real valued L\'evy process that is in the domain of attraction of a stable law without centering with norming function $c.$ As an analogue of the random walk results in \cite{vw...
On the passage from atomistic systems to nonlinear elasticity theory
nonlinear elasticity theory Analysis of PDEs
2011/9/16
Abstract: We derive continuum limits of atomistic models in the realm of nonlinear elasticity theory rigorously as the interatomic distances tend to zero. In particular we obtain an integral functiona...
Polarization squeezing of light by single passage through an atomic vapor
Polarization squeezing single passage atomic vapor
2011/8/17
Abstract: We have studied relative-intensity fluctuations for a variable set of orthogonal elliptic polarization components of a linearly polarized laser beam traversing a resonant $^{87}$Rb vapor cel...
The asymptotic shape, large deviations and dynamical stability in first-passage percolation on cones
The asymptotic shape dynamical stability cones Probability
2011/9/2
Abstract: In this paper we consider first-passage percolation on certain subgraphs of the $\Z^d$ nearest neighbour graph. We present a three-fold extension of the Shape Theorem. Firstly, we show that ...
Asymptotics of first-passage percolation on 1-dimensional graphs
Asymptotics of first-passage percolation 1-dimensional graphs Probability
2011/9/2
Abstract: In this paper we consider standard first-passage percolation on certain 1-dimensional periodic graphs. One such graph of particular interest is the $\Z\times\{0,1,...,K-1\}^{d-1}$ nearest ne...
Scaling properties of first-passage time probabilities in financial markets
financial markets first-passage time probability Statistical Finance
2011/9/29
Abstract: Financial markets provide an ideal frame for the study of first-passage time events of non-Gaussian correlated dynamics mainly because large data sets are available. Tick-by-tick data of six...
