Frequency-Dependent Selection at Rough Expanding Fronts [PDF]

open access: yes, 2015
Microbial colonies are experimental model systems for studying the colonization of new territory by biological species through range expansion. We study a generalization of the two-species Eden model, which incorporates local frequency-dependent ...

Influence of the male ejaculate on post-mating prezygotic barriers in field crickets. [PDF]

open access: yesPLoS ONE, 2012
Post-copulatory interactions between males and females involve highly coordinated, complex traits that are often rapidly evolving and divergent between species.

Unified Cross-Layer Framework: A Generic Platform for Cross-Layer Design Experimentation [PDF]

open access: yes2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
Cross-layer designs in wireless network systems have been an active research area. Numerous cross-layer schemes are proposed to increase overall system performance by allowing information to be shared and controlled across protocol layers. However, the majority of the previous research work in this area is theoretic.

Genetics of resistance to stored grain weevil (Sitophilus oryzae L.) in maize

open access: yesCogent Food & Agriculture, 2015
Stored grain weevil (Sitophilus oryzae) has emerged as important storage grain pest of maize, causing substantial economic losses. Owing to high costs and environmental hazards of pesticides, host plant resistance holds promise for effective control of ...

Selection Indices Studies in Maize (Zea mays L.) under Multiple Abiotic Stress Conditions

open access: yesInternational Journal of Bio-Resource and Stress Management, 2023
The present investigation was undertaken on maize (Zea mays L.) under two abiotic stress conditions viz. low-nitrogen (low soil fertility) and excess soil moisture conditions (waterlogging) during kharif 2010.

Magnetism of Cold Fermionic Atoms on p-Band of an Optical Lattice

open access: yes, 2008
We carry out \textit{ab initio} study of ground state phase diagram of spin-1/2 cold fermionic atoms within two-fold degenerate $p$-band of an anisotropic optical lattice.

Experimental study of crossing angle collision [PDF]

open access: yesProceedings of International Conference on Particle Accelerators, 2002
The non-linear coupling due to the beam-beam interaction with crossing angle has been studied. The major effect of a small (/spl sim/12 mrad) crossing angle is to excite 5Q/sub xspl plusmn/Q/sub s/ integer coupling resonance family on large amplitude particles, which results in bad lifetime, On the CESR, a small crossing angle (/spl sim/2.4 mr) was ...

A lethal effect associated with polymorphism of the NOR-bearing chromosomes in rainbow trout (Oncorhynchus mykiss)

open access: yesGenetics and Molecular Biology, 2004
Cytogenetic analysis of a rainbow trout stock showed that the nucleolar organizing regions were located subterminally on the long arm of a submetacentric chromosome pair and occurred as a single chromosomal segment (phenotype N1) or as two chromosomal ...

Fourteen years of R/qtl: Just barely sustainable

open access: yes, 2014
R/qtl is an R package for mapping quantitative trait loci (genetic loci that contribute to variation in quantitative traits) in experimental crosses. Its development began in 2000. There have been 38 software releases since 2001.

Inheritance of disc flower color in Helianthus petiolaris [PDF]

open access: yes, 2009
Disc flowers of Helianthus petiolaris (Asteraceae) are usually purple reddue to anthocyanin pigments in corolla lobes, style and stigma. However, yellow-flowered plants are occasionally found.
