Species distribution model transferability and model grain size – finer may not always be better

Scientific Reports, 2018
Species distribution models have been used to predict the distribution of invasive species for conservation planning. Understanding spatial transferability of niche predictions is critical to promote species-habitat conservation and forecasting areas ...

Grain-size distribution of volcaniclastic rocks 2: Characterizing grain size and hydraulic sorting [PDF]

Journal of Volcanology and Geothermal Research, 2015
Quantification of the grain size distribution of sediments allows interpretation of processes of transport and deposition. Jutzeler et al. (2012) developed a technique to determine grain size distribution of consolidated clastic rocks using functional stereology, allowing direct comparison between unconsolidated sediments and rocks.

Identification of SMG3, a QTL Coordinately Controls Grain Size, Grain Number per Panicle, and Grain Weight in Rice

Frontiers in Plant Science, 2022
Grain size, grain number per panicle, and grain weight are key agronomic traits that determine grain yield in rice. However, the molecular mechanisms coordinately controlling these traits remain largely unknown.

The Effects of Grain Size and Temperature Distributions on the Formation of Interstellar Ice Mantles [PDF]

, 2015
Computational models of interstellar gas-grain chemistry have historically adopted a single dust-grain size of 0.1 micron, assumed to be representative of the size distribution present in the interstellar medium. Here, we investigate the effects of a broad grain-size distribution on the chemistry on dust-grain surfaces and the subsequent build-up of ...

Size-dependent electronic-transport mechanism and sign reversal of magnetoresistance in Nd0.5Sr0.5CoO3

, 2012
A detailed investigation of electronic-transport properties of Nd0.5Sr0.5CoO3 has been carried out as a function of grain size ranging from micrometer order down to an average size of 28 nm.

Effects of GS3 and GL3.1 for Grain Size Editing by CRISPR/Cas9 in Rice

Rice Science, 2020
Grain size is one of key agronomic traits associated with grain yield and grain quality. Both major quantitative trait loci GS3 and GL3.1 play a predominant role in negative regulation of grain size. In this study, a CRISPR/Cas9-mediated multiplex genome

The Elite Alleles of OsSPL4 Regulate Grain Size and Increase Grain Yield in Rice

Rice, 2021
Grain weight and grain number, the two important yield traits, are mainly determined by grain size and panicle architecture in rice. Herein, we report the identification and functional analysis of OsSPL4 in panicle and grain development of rice.

Occurrence, Risk Factors, and Prognosis of Acute Cerebral Microinfarcts in CADASIL

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common monogenic cerebral small vessel disease in adults. This study investigates the occurrence, risk factors, and prognosis of acute cerebral microinfarcts (ACMIs) in patients with CADASIL.

Effect of stochastic grain heating on cold dense clouds chemistry [PDF]

, 2018
The temperatures of dust grains play important roles in the chemical evolution of molecular clouds. Unlike large grains, the temperature fluctuations of small grains induced by photons may be significant. Therefore, if the grain size distribution is included in astrochemical models, the temperatures of small dust grains may not be assumed to be ...

Hard-core thinnings of germ-grain models with power-law grain sizes [PDF]

Advances in Applied Probability, 45(3):595-625, 2013, 2012
Random sets with long-range dependence can be generated using a Boolean model with power-law grain sizes. We study thinnings of such Boolean models which have the hard-core property that no grains overlap in the resulting germ-grain model. A fundamental question is whether long-range dependence is preserved under such thinnings. To answer this question
