The Nanoimprint lithography (NIL) is a novel method of fabricating micro/nanometer scale patterns with low cost, high throughput and high resolution (Chou et al., 1996). Unlike traditionally optical lithographic approaches, which create pattern through the use of photons or electrons to modify the chemical and physical properties of the resist, NIL relies on direct mechanical deformation of the...

The chromatic number of a Latin square is the least number of partial transversals which cover its cells. This is just the chromatic number of its associated Latin square graph. Although Latin square graphs have been widely studied as strongly regular graphs, their chromatic numbers appear to be unexplored. We determine the chromatic number of a circulant Latin square, and find bounds for some ...

In this paper, we construct three new extremal lattices of minimum 8; one is 3-modular and of dimension 40, the two others are unimodular of dimension 80. They are strongly connected to the 20-dimensional lattice with automorphism group isomorphic to 2:M 22 :2.

For strongly regular graphs with adjacency matrix A, we look at the binary codes generated by A and A+ I . We determine these codes for some families of graphs, we pay attention to the relation between the codes of switching equivalent graphs and, with the exception of two parameter sets, we generate by computer the codes of all known strongly regular graphs on fewer than 45 vertices.

the counters of e to become nil: message tokense] is decremented by 1, but nil tokense] is incremented by 1. 2 Proof of Lemma 2: Let t be the time just before the token is sent from u, and t 0 the time just before it is received at v. Because the sum of message tokens and nil tokens can increment only when tokens arrive on the link, and because the links are FIFO, we have: message tokense] t 0 ...

up By the induction hypothesis P fulfil the requirements. Let be a node in P’s frontier that such that P( ) = ht;Ri is non-trivial, and let P( ) = ht 0;R 0i be a non-trivial ancestor such that t 0 t. Let t 0 u t = (s; fx1:=s1; : : : ; xn :=sng; ). Since t 0 6$ t, s is not a variable. Also, since t 0 6 lt, then sfx1:= s1; : : : ; xn := sng 6 : = s. Hence the abstract operation is welldefined and...

Let X be a pseudocyclic association scheme in which all the nontrivial relations are strongly regular graphs with the same eigenvalues. We prove that the principal part of the first eigenmatrix of X is a linear combination of an incidence matrix of a symmetric design and the all-ones matrix. Amorphous pseudocyclic association schemes are examples of such association schemes whose associated sym...

in the current paper, finite element method is employed for numerical simulations and the study of influential parameters on elastic modulus of polymer-matrix nano-composites. effects of different key parameters including particle elastic modulus, interphase elastic modulus, matrix elastic modulus, interphase thickness and particle volume fraction on total elastic modulus of nano-composite mate...

Increases in rates of individual leaf photosynthesis (P n) are critical for future increases of rice yields. A previous study, using introgression lines derived from a cross between indica cultivar Habataki, with one of the highest recorded values of P n, and the Japanese elite cultivar Koshihikari, identified four QTLs (qCAR4, qCAR5, qCAR8, and qCAR11) that affect P n. The present study examin...

The potential of solid phase extraction (SPE) clean-up has been assessed to reduce matrix effects (signal suppression or enhancement) in the liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis of lipophilic marine toxins. A large array of ion-exchange, silica-based, and mixed-function SPE sorbents was tested. Polymeric sorbents were found to retain most of the toxins. Optimizatio...
