We present a polynomial time greedy algorithm that assigns proper wavelengths to a set of requests of maximum load L per directed ber link on a directed ber tree using at most 5=3L wavelengths. This improves previous results of 12, 10, 8, 9]. We also prove that no greedy algorithm can in general use less than 5=3L wavelengths for a set of requests of load L in a directed ber tree, and thus our ...

In this project, the operation and the features of a new three-level converter are presented with PV source and boost converter. The proposed topology was named three-level active-stacked neutral point clamped. It is a derivative of the 3L-SNPC structure, having two additional active switches connected anti parallel with the clamp diodes. The main advantage of 3L-ASNPC converter is the reductio...

BRAF mutations occur in 8% to 12% of patients with mCRC and are associated clinically poor prognosis. E+C was approved by the FDA EMA for V600E-mutant who have received prior systemic therapy based on results BEACON study (NCT02928224), which combined treated second- (2L) third-line (3L) setting. Here we evaluate characteristics outcomes separately 2L 3L or control. a phase 3, open label evalua...

The possibility to determine sparticle masses in the 3l + no jets + Emiss T final states from ~ 1 ~ 02 pair production is studied. It is based on the kinematics of ~ 02 ! l+l ~ 01 and ~ 02 ! l ~l L;R ! l+l ~ 01 leptonic decays. The analysis is carried out within the framework of the minimal SUGRA model, where the mass measurement of the lightest neutralino ( ~ 01) allows to constrain the common...

We prove that for the class of three-colorable triangulations of a closed oriented surface, the degree of a four-coloring modulo 12 is an invariant under Kempe changes. We use this general result to prove that for all triangulations T (3L, 3M) of the torus with 3 ≤ L ≤ M , there are at least two Kempe equivalence classes. This result implies in particular that the Wang–Swendsen–Kotecký algorith...

The photo-induced substitution of a CO ligand in Cp*Ta(CO)4 (1) has been used to pre­ pare a series of Cp*Ta(CO)3L (2) complexes, in which the two-electron ligand L includes, e.g., isonitriles, sulfanes, cyclic ethers, phosphanes and pyridines. The complexes (2a-y) were characterized by their v(CO) frequencies and their ’H and 13C NMR spectra, and were compared if possible with the correspondin...

background preference weights for eq-5d-3l based on visual analogue scale (vas) has recently been developed in iran. the aim of the current study was to compare performance of this value set against the uk vas-based value set.   methods the mean scores for all possible 243 health states were compared using student t test. absolute agreement and consistency were investigated using concordance co...

Combining implicit polynomials and algebraic invariants for representing and recognizing complicated objects proves to be a powerful technique. However, a basic requirement for using implicit polynomials for affine invariant recognition is to have an affine invariant fitting algorithm. In this paper, we study the problem of affine invariant fitting of an implicit polynomial to data. Received Ja...

Precise second-harmonic generation spectra of monolayer (ML)-MoS2, trilayer (3L)-MoS2 with a 3R structure, and 3L-MoS2 2H structure are measured in the two-photon energy region from 2.4 to 3.2 eV. The resolved into two components, C1 C2. As number layers increases ML- 3L-MoS2, peak low-energy component, C1, is red-shifted its width broadens. Peak intensity also higher for compared ML-MoS2.
