Compared with ampicillin, oxacillin, cefmetazole and imipenem, the combination of ampicillin and sulbactam at a constant ratio of 2:1 showed the greatest effect against 28 clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA), but MICs of ampicillin/sulbactam were still above the resistance breakpoint. When ampicillin/sulbactam was further… (More)

INTRODUCTION
Current evidence shows that laparoscopic bowel surgery is associated with a lower incidence of postoperative ileus, lower postoperative pulmonary and wound complication rates, shorter hospital stays and a quicker return to activity than open surgery. This paper aims to report our early experience with laparoscopic-assisted colorectal procedures… (More)

The Gallant-Lambert-Vanstone (GLV) method is a very ef-cient technique for accelerating point multiplication on elliptic curves with eciently computable endomorphisms. Galbraith, Lin and Scott (J. Cryptol. 24(3), 446-469 (2011)) showed that point multiplication exploiting the 2-dimensional GLV method on a large class of curves over F p 2 was faster than the… (More)

Let p 1, p 2,…,p r be distinct odd primes and m = p 1 p 2⋯p r . Let f(x) be a primitive polynomial of degree n over ℤ / m ℤ $\mathbb {Z}/m\mathbb {Z}$ . Denote by L(f) the set of primitive linear recurring sequences generated by f(x). A map ψ on ℤ / m ℤ $\mathbb {Z}/m\mathbb {Z}$ naturally induces a map ψ ̂ $\widehat {\psi }$ on L(f), mapping a sequence ( …… (More)

This paper introduces a special family of twisted Edwards curve named Optimal mixed Montgomery-Edwards (OME) curves. The OME curve is proposed by exploiting the fact that every twisted Edwards curve is birationally equivalent to some elliptic curve in Montgomery form. The OME curves achieve optimal group arithmetic for both of twisted Edwards model and… (More)

The verification of an ECDSA signature requires a double-base scalar multiplication, an operation of the form k · G + l · Q where G is a generator of a large elliptic curve group of prime order n, Q is an arbitrary element of said group, and k, l are two integers in the range of [1, n − 1]. We introduce in this paper an area-optimized VLSI design of a… (More)
