SEA ICE DRIFT MONITORING IN THE BOHAI SEA BASED ON GF4 SATELLITE
GF4 image Sea ice Sift MCC Monitor
2018/5/17
The Bohai Sea is the inland sea with the highest latitude in China. In winter, the phenomenon of freezing occurs in the Bohai Sea due to frequent cold wave influx. According to historical records, the...
Drift, selection, or migration? Processes affecting genetic differentiation and variation along a latitudinal gradient in an amphibian
Genetic drift Natural selection Major histocompatibility complex
2017/8/25
Past events like fluctuations in population size and post-glacial colonization processes may influence the relative importance of genetic drift, migration and selection when determining the present da...
Cardiovascular Drift during Training for Fitness in Patients with Metabolic Syndrome
HEART RATE DRIFT AEROBIC TRAINING FITNESS EXERCISE PRESCRIPTION ENERGY EXPENDITURE METABOLIC SYNDROME
2018/4/24
Purpose The health benefits of a training program are largely influenced by the exercise dose and intensity. We sought to determine whether during a training bout of continuous versus interval exercis...
Putting Process and Product Conceptions of Natural Selection and Genetic Drift to the Test
natural selection genetic drift process product outcome causation
2016/6/15
This paper argues for two claims. First, despite a persistent appearance to the contrary in the philosophy of biology literature, the question of whether natural selection and genetic drift should be ...
New concepts for space-borne monitoring of drift and 3D morphology of cloud fields for weather forecast and climate research
Cloud Height Cloud Drift Stereoscopy
2016/5/20
Cloud screening and tracking by geostationary satellites (GEO) is presently the main information source for estimating cloud
coverage and drift for weather forecast and climate research. The coarse p...
he dominant feature in the magnetic declination record at all European sites for which adequate data are available is a minimum between 1750 and 1860. The time of minimum at different sites correlates...
We study a particle moving at unit speed in a channel made by
connected self-similar billiard tables that grow in size by a factor r > 1

ASYMPTOTIC EQUIVALENCE OF ESTIMATING A POISSON INTENSITY AND A POSITIVE DIFFUSION DRIFT
ASYMPTOTIC EQUIVALENCE ESTIMATING A POISSON INTENSITY POSITIVE DIFFUSION DRIFT
2015/8/25
We consider a diffusion model of small variance type with positive drift density varying in a nonparametric set. We investigate Gaussian and Poisson approximations to this model in the sense of asympt...
Satellites Reveal the Influence of Equatorial Currents and Tropical Instability Waves on the Drift of the Kon-Tiki in the Pacific
Equatorial Currents Tropical Instability Waves
2015/7/29
A raft drifting on the ocean is at the mercy of the elements. When a sailor describes this experience, one begins to understand the meaning of "in situ," of being in touch with the water. The senses f...
The Role of Active Muscle Mass on Exercise-Induced Cardiovascular Drift
Prolonged cycling cardiovascular regulation
2015/4/13
The purpose of this study was to examine the role of active muscle mass on cardiovascular drift (CVdrift) during prolonged exercise. Twelve subjects with peak oxygen uptake (VO2peak) of 3.52 ± 0.52 L·...

Accurate estimates of soil organic carbon (SOC)
stocks are required to quantify carbon sources and sinks
caused by land use change at national scale.
Accent Classes in South Kyengsang Korean: Lexical Drift, Novel Words, and Loanwords
Accent Classes South Kyungsang Korean Lexical Drift Novel Words Loanwords
2014/11/12
Over the past decade, the investigation of various kinds of lexical frequency effects has emerged as a prominent line of research in generative phonology. Some of the more influential studies include ...
Experimental Observation of Low Noise and Low Drift in a Laser-Driven Fiber Optic Gyroscope
Backscattering drift backscattering noise fi ber optic gyroscope laser phase noise
2015/8/7
We demonstrate that by driving a fiber optic gyroscope (FOG) with a laser of relatively broad linewidth( ), both the noise and the bias drift are reduced to very low levels (0.058 and 1.1 , resp...

2013/4/28
We consider a reflected Ornstein-Uhlenbeck process driven by a fractional Brownian motion with Hurst parameter $H\in(0,1)$. Our goal is to estimate an unknown drift parameter $\alpha\in (-\infty,\inft...
