The present study aspired to scrutinize the relationship among EFL learners' Self-directed Learning (SL), Resilience (RE), and Willingness to Communicate (WTC). To accomplish this purpose, 124 male and female undergraduate EFL learners, within the age range of 20 to 32, were selected through convenience sampling. These EFL learners were asked to fill in three questionnaires, namely the SL...

Sl/Sld mutant mice are profoundly deficient in tissue mast cells as a result of a defect in the microenvironment promoting the development of these cells. To facilitate the analysis of the Sl mutation, we attempted to establish an in vitro system in which the in vivo defect of Sl/Sld mice could be reproduced. 3T3 cell lines were established from 17-day-old embryos of Sl/Sld and congenic +/+ gen...

BACKGROUND The study was conducted to compare the outcomes of sleeve lobectomy (SL) and pneumonectomy (PN) for management of the left lung in patients with non-small cell lung cancer (NSCLC). METHODS One hundred and thirty-five patients who underwent left SL (n = 87) or left PN (n = 48) for NSCLC from January 2006 to December 2011 were enrolled in this retrospective study. Left SL was perform...

In this paper nondegenerate multidimensional matrices of boundary format in V0 ⊗ · · · ⊗ Vp are investigated by their link with Steiner vector bundles on product of projective spaces. For any nondegenerate matrix A the stabilizer for the SL(V0)×· · ·×SL(Vp)action, Stab(A), is completely described. In particular we prove that there exists an explicit action of SL(2) on V0 ⊗ · · · ⊗ Vp such that ...

Double-layer quantum Hall systems possess interlayer phase coherence at sufficiently small layer separations, even without interlayer tunneling. When interlayer tunneling is present, application of a sufficiently strong in-plane magnetic field B i.Bc drives a commensurate-incommensurate ~CI! transition to an incommensurate soliton-lattice ~SL! state. We calculate the Hartree-Fock ground-state e...

Denote the free group on 2 letters by F2 and the SL(2,C)-representation variety of F2 by R = Hom(F2, SL(2,C)). The group SL(2,C) acts on R by conjugation. We construct an isomorphism between the coordinate ring C[SL(2,C)] and the ring of matrix coefficients, providing an additive basis of C[R]SL(2,C) in terms of spin networks. Using a graphical calculus, we determine the symmetries and multipli...

In this paper, we investigate model checking algorithms for variants of strategy logic over pushdown multi-agent systems, modeled by pushdown game structures (PGSs). We consider various fragments of strategy logic, i.e., SL[CG], SL[DG], SL[1G] and BSIL. We show that the model checking problems on PGSs for SL[CG], SL[DG] and SL[1G] are 3EXTIME-complete, which are not harder than the problem for ...

in this paper we will give the character table of the irreducible rational representations of g=sl (2, q) where q= , p prime, n>o, by using the character table and the schur indices of sl(2,q).

The hormone ethylene regulates a wide range of plant developmental processes and EBF (EIN3-binding F-box) proteins were shown to negatively regulate the ethylene signalling pathway via mediating the degradation of EIN3/ EIL proteins. The present study reports on the identification of two tomato F-box genes, Sl-EBF1 and Sl-EBF2 from the EBF subfamily. The two genes display contrasting expression...
