Effect of Drought Stress at Pre and Post-anthesis on Dry Matter Accumulation of Grains in Irrigated Winter Wheat [PDF]

open access: yesIkufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2011
Investigating assimilate contribution and grain filling pattern in winter wheat is importance under drought stress condition. This study was conducted to evaluate the relationship between drought stress on grain filling and yield of 4 cultivars including

Game theoretic aspects of distributed spectral coordination with application to DSL networks

open access: yes, 2006
In this paper we use game theoretic techniques to study the value of cooperation in distributed spectrum management problems. We show that the celebrated iterative water-filling algorithm is subject to the prisoner's dilemma and therefore can lead to ...

Massive Spin Collective Mode in Quantum Hall Ferromagnet

open access: yes, 2003
It is shown that the collective spin rotation of a single Skyrmion in quantum Hall ferromagnet can be regarded as precession of the entire spin texture in the external magnetic field, with an effective moment of inertia which becomes infinite in the zero

Spin Relaxation in a Quantized Hall Regime in Presence of a Disorder

open access: yes, 2003
We study the spin relaxation (SR) of a two-dimensional electron gas (2DEG) in the quantized Hall regime and discuss the role of spatial inhomogeneity effects on the relaxation.

Seed Filling Trend of Faba bean (Vicia faba L.) as Affected by Planting Date and Density [PDF]

open access: yesIkufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2016
To investigate the effect of planting date and plant density on phenology, seed yield, its components, seed filling rate and grain filling period of faba bean, a factorial experiment based on randomized complete block design with four replications was ...

Recruiting Intensity during and after the Great Recession: National and Industry Evidence [PDF]

open access: yes
We measure job-filling rates and recruiting intensity per vacancy at the national and industry levels from January 2001 to September 2011 using data from the Job Openings and Labor Turnover Survey.

Magnetic phenomena at and near nu =1/2 and 1/4: theory, experiment and interpretation

open access: yes, 2000
I show that the hamiltonian theory of Composite Fermions (CF) is capable of yielding a unified description in fair agreement with recent experiments on polarization P and relaxation rate 1/T_1 in quantum Hall states at filling nu = p/(2ps+1), at and near

Long-Wavelength, Free-Free Spectral Energy Distributions from Porous Stellar Winds

open access: yes, 2016
The influence of macroclumps for free-free spectral energy distributions (SEDs) of ionized winds is considered. The goal is to emphasize distinctions between microclumping and macroclumping effects.
