DNA links male female butterfly distinct species
2017/9/1
Researchers recently discovered what was thought to be a distinct species of butterfly is actually the female of a species known to science for more than a century.An international team of nine butter...
Super-resolution fluorescence of huntingtin reveals growth of globular species into short fibers and coexistence of distinct aggregates.
Super-resolution fluorescence huntingtin reveals growth globular species into short fibers coexistence distinct aggregates
2015/12/11
Polyglutamine-expanded huntingtin, the protein encoded by HTT mutations associated with Huntington's disease, forms aggregate species in vitro and in vivo. Elucidation of the mechanism of growth of fi...
Chemistry,Temperature,and Faunal Distributions at Diffuse-Flow Hydrothermal Vents:Comparison of Two Geologically Distinct Ridge Systems
Chemistry Temperature Faunal Distributions Diffuse-Flow Hydrothermal Vents Two Geologically Distinct Ridge Systems
2015/7/14
Diffuse-flow, low-temperature areas near hydrothermal vents support life via chemosynthesis: hydrogen sulfide (and other reduced chemical compounds) emanating from the subsurface is oxidized with bott...
DISTINCT LOCALIZATION OF NADPH OXIDASE FLAVOCYTOCHROME B IN RESTING AND INTERFERON GAMMA ACTIVATED MACROPHAGES
Host defense superoxide
2015/5/21
Flavocytochrome b558, the catalytic core of the phagocytic NADPH oxidase, mediates the transfer of electrons from NADPH to molecular oxygen to generate superoxide for host defense. Flavocytochrome b i...
The sensitivity of GNSS measurements in Fennoscandia to distinct three-dimensional upper-mantle structures
GNSS measurements Fennoscandia three-dimensional upper-mantle structures
2015/1/6
The sensitivity of global navigation satellite system (GNSS) measurements in Fennoscandia to nearby viscosity variations in the upper mantle is investigated using a 3-D finite element model of glacial...
Overlapping and distinct functions for Gli proteins: Key mediators of hedgehog signaling in cell specification during embryonic development
Signals embryonic tissue cell differentiation the central nervous system the pituitary gland the pancreas cells
2014/12/11
Hedgehog (Hh) signaling is important for patterning and cell differentiation within many embryonic tissues. Hh is expressed in the notochord and the floor plate and acts as a morphogen in patterning o...
Oxygen isotopes as a valuable tool for measuring annual growth in tropical trees that lack distinct annual rings
tropical tree with non-distinct annual rings cellulose oxygen isotopes fractionation model Styrax tonkinensis Ficus semicordata var. semicordata
2017/4/11
Some trees from tropical areas lack visually detectable and consistent annual growth rings. As such, we have measured
the radial variation of cellulose oxygen isotopes in trees that grow in seasonall...
Fine spatial structure of genetically distinct picocyanobacterial populations across environmental gradients in the Costa Rica Dome
Fine spatial structure genetically distinct picocyanobacterial populations across environmental gradients in the Costa Rica Dome
2014/4/2
We investigated the spatial variability of picocyanobacterial community structure across the Costa Rica Dome(CRD), an offshore upwelling system characterized by high seasonal abundance of Synechococcu...
The importance of distinct modeling strategies for gene and gene-specific treatment effects in hierarchical models for microarray data
Diffierential expression EM algorithm hierarchical models random effects uncertainty
2012/11/23
When analyzing microarray data, hierarchical models are often used to share information across genes when estimating means and variances or identifying differential expression. Many methods utilize so...
Distinct zeros and simple zeros of Dirichlet $L$-functions
simple zeros distinct zeros Dirichlet L-function
2012/6/29
We study the number of distinct zeros and simple zeros of Dirichlet $L$-function by using Asymptotic Large Sieve in this paper. In asymptotic terms, we prove that there are more than 66.43% of zeros o...
Permutations all of whose patterns of a given length are distinct
Permutations a given length distinct Combinatorics
2012/6/21
For each integer k >= 2, let F(k) denote the largest n for which there exists a permutation \sigma \in S_n, all of whose patterns of length k are distinct. We prove that F(k) = k + \lfloor \sqrt{2k-3}...
A new scientific study has identified two distinct populations of white shark at the east and west of Bass Strait in Australian waters, prompting researchers to suggest the huge fish may need regional...
THE HAND1 LINEAGE REVEALS DISTINCT ROLES FOR HAND FACTORS DURING CARDIOVASCULAR DEVELOPMENT
Development Gene expression
2015/5/21
The basic Helix-Loop-Helix (bHLH) transcription factors Hand1 and Hand2 play critical roles in the development of multiple organ systems during embryogenesis. The dynamic expression patterns of these ...
Evolutionary branching in a stochastic population model with distinct mutational steps
Evolutionary branching genetic drift selection adaptation
2012/5/2
Evolutionary branching is analysed in a stochastic, individual-based population model under mutation and selection. In such models, the common assumption is that individual reproduction and life caree...
