Application of Some Drought Stress Indices to Study Response of Durum Wheat Triticum durum to Different Levels of Water Depletion

open access: yesTikrit Journal for Agricultural Sciences, 2021
A pot experiment was conducted to investigate the effect of five levels of soil water depletion from field capacity (30, 40, 50, 60, and 70%) on some growth, yield and yield components of durum wheat (Triticum durum L.) VAR-ACSAD/65, with testing ten ...

Soliton ratchets induced by ac forces with harmonic mixing [PDF]

open access: yes, 2001
The ratchet dynamics of a kink (topological soliton) of a dissipative sine-Gordon equation in the presence of ac forces with harmonic mixing (at least bi-harmonic) of zero mean is studied.

A Branch-and-Bound Algorithm for Minimizing the Total Tardiness of Multiple Developers

open access: yesMathematics, 2022
In the game industry, tardiness is an important issue. Unlike a unifunctional machine, a developer may excel in programming but be mediocre in scene modeling. His/her processing speed varies with job type. To minimize tardiness, we need to schedule these

Experimental Demonstration of Squeezed State Quantum Averaging [PDF]

open access: yes, 2010
We propose and experimentally demonstrate a universal quantum averaging process implementing the harmonic mean of quadrature variances. The harmonic mean protocol can be used to efficiently stabilize a set of fragile squeezed light sources with ...

Weakly convex biharmonic hypersurfaces in nonpositive curvature space forms are minimal

open access: yes, 2013
A submanifold $M^m$ of a Euclidean space $R^{m+p}$ is said to have harmonic mean curvature vector field if $\Delta \vec{H}=0$, where $\vec{H}$ is the mean curvature vector field of $M\hookrightarrow R^{m+p}$ and $\Delta$ is the rough Laplacian on $M ...

Thermal energies of classical and quantum damped oscillators coupled to reservoirs [PDF]

open access: yes, 2016
We consider the global thermal state of classical and quantum harmonic oscillators that interact with a reservoir. Ohmic damping of the oscillator can be exactly treated with a 1D scalar field reservoir, whereas general non-Ohmic damping is conveniently ...
