We study the essential spectra of formally self-adjoint elliptic systems on doubly periodic planar domains perturbed by a semi-infinite periodic row of foreign inclusions.
Weight-balanced and doubly stochastic digraphs are two classes of digraphs that play an essential role in a variety of coordination problems, including formation control, agreement, and distributed optimization.
SEM, XRD and TPR analyses demonstrate that highly dispersed, doubly promoted Ni catalysts with a strong metal-support interaction are essential for stable dry reforming and suppression of the formation of carbon filaments.
There was the hefty seventy-fifth-anniversary anthology, in 1999, followed by the doubly hefty "Complete Cartoons," in 2004; bushels of titles by Leo Cullum, Jack Ziegler, Danny Shanahan, and Bruce Eric Kaplan, as well as the Essential series (The Essential Charles Barsotti, Booth, etc)., by Lee Lorenz.
In the design of a Doubly Fed Induction Generator (DFIG), the electrical, dielectric, magnetic, thermal, and mechanical considerations are essential in the design.
Early embryonic lethality in mice doubly deficient for both IRPs (Ref. 44) shows that the IRP IRE regulatory system is essential.
This is doubly unconvincing.
It's doubly embarrassing".
