Fish are a rich source of omega-3 polyunsaturated fatty acids (n-3 PUFAs) and thus, they should be an integral part of human diet at least twice a week. As a result, high attention has been devoted to...
Two single nucleotide polymorphisms in the caprine GnIH gene are associated with litter size
PCR-RFLP SNPs combined genotype candidate gene

Gonadotropin-inhibitory hormone (GnIH) can decrease luteinizing hormone and/or follicle-stimulating hormone levels in rat, mouse, sheep, and cattle by the direct suppression of gonadotropin-releasing ...
Size fractionation of nanoparticulate metal sulfides in oxic water of Lake Teganuma, Japan
metal sulfides nanoparticle size fractionation acid volatile sulfides Lake Teganuma
2017/4/10
Concentrations of acid volatile sulfides (AVS) as metal sulfides in three different size fractions (<30 nm, 30–200 nm,
>200 nm) at Lake Teganuma were measured using a nano-filtration followed by a pu...
Geological factors responsible for REY-rich mud in the western North Pacific Ocean: Implications from mineralogy and grain size distributions

Seven piston cores were collected from the seafloor ~250 km south of Minamitorishima Island in the western North
Pacific Ocean during the cruise KR13-02 of R/V Kairei; in some portions of cores PC04 ...
A comparison between rubble-pile and monolithic targets in impact simulations:Application to asteroid satellites and family size distributions
Asteroids Collisional physics Impact processes Satellites, General
2015/12/25
Collisions are a fundamental process in the creation of asteroid families and in satellite formation. For this reason, understanding the outcome of impacts is fundamental to the accurate modeling of t...
Collisional evolution and reddening of asteroid surfaces–I. The problem of conflicting time-scales and the role of size-dependent effects

2015/12/25
Space weathering is the generic term used for processes that modify the optical properties of surfaces of atmosphereless rocky bodies under exposure to the space environment. The general agreement abo...
Size–frequency distributions of fragments from SPH/N-body simulations of asteroid impacts: Comparison with observed asteroid families
Asteroids Collisional physics Impact processes
2015/12/25
We investigate the morphology of size–frequency distributions (SFDs) resulting from impacts into 100-km-diameter parent asteroids, represented by a suite of 161 SPH/N-body simulations conducted to stu...

There is increasing evidence for variation in
rates of nucleotide substitution among divergent taxonomic
groups. Here, we summarize published rate data and show a
strong relationship between substi...
Tree size frequency distributions, plant density, age and community disturbance

2015/8/27
We show that explicit mathematical and biological relationships exist among the scaling exponents and the allometric constants (a and b, respectively) of log–log linear tree-community size frequency d...
Size-dependent species richness:trends within plant communities and across latitude
Community ecology plant size species packing species richness
2015/8/27
We examine how species richness and species-specific plant density (number of species and number of individuals per species, respectively) vary within community size frequency distributions and across...
Finite size scaling for the core of large random hypergraphs
Core random hyper-graph random graph low-density parity-check codes XOR-SAT fi nite size scaling
2015/8/21
The (two) core of an hyper-graph is the maximal collection of hyper-edges within which no vertex appears only once. It is of importance in tasks such as efficiently solving a large linear system over ...
Modern scientific technology has provided a new class of large-scale simultaneous inference
problems, with thousands of hypothesis tests to consider at the same time. Microarrays epitomize this...
