BACKGROUND K2 or "spice" has emerged as a popular legal alternative to marijuana among adolescents and young adults. However, no data has been published assessing prevalence of and associations with ever K2 use in any population. This study's aims were to examine prevalence of ever K2 use among a sample of college students, to determine characteristics of persons who use K2, and to access the a...

 a−c−bq1 2b if a−c−bq1 2b < (0 2 + k2)ξ, (0 2 + k2)ξ if a−c−bq1 2b ≥ (0 2 + k2)ξ. Solving for the intersection of the best response functions q 1(q2) and q ∗ 2(q1), we can obtain the equilibrium order quantities and hence the equilibrium profits shown in Lemma 1. Discussion about when a−c 3b( k0 2 +k2) > 1. We observe that when a−c 3b( k0 2 +k2) > 1, there are two cases. Case 1. When a−c b( 3k...

CLC-K2, a kidney-specific member of the CLC chloride channel family, is thought to play an important role in the transepithelial Cl(-) transport in the kidney. This consensus was first reached shortly after it was demonstrated that the mutations of the human CLCNKB gene resulted in Bartter's syndrome type III. To clarify the pathogenesis, the exact intrarenal and cellular localization of CLC-K2...

We present the first results of K2-OjOS, a collaborative project between professional and amateur astronomers primarily aimed to detect, characterize, validate new extrasolar planets. For this work, 10 looked for planetary signals by visually inspecting 20 427 light curves K2 campaign 18 (C18). They found 42 planet candidates, which are detections 24 had been detected in overlapping C5 previous...

Over the last decade the NA48 collaboration at CERN has carried out an extensive experimental program dedicated to study CP violation (CPV) and rare processes in both neutral and charged kaon decays. A selection of results from recent analysis is compared with other measurements and theoretical predictions to provide constraints on CPV and on the CKM matrix. The observable +is related to the p...

In this paper we provide the first side-channel analysis of the K2 stream cipher. K2 is a fast and secure stream cipher built upon the strengths of SNOW 2.0. We apply timing attacks, power analysis, and differential fault analysis to K2. We show that naively implemented K2 is vulnerable to cache-timing attacks, and describe how to implement efficient countermeasures to protect K2 against side-c...

a vertex irregular total k-labeling of a graph g with vertex set v and edge set e is an assignment of positive integer labels {1, 2, ..., k} to both vertices and edges so that the weights calculated at vertices are distinct. the total vertex irregularity strength of g, denoted by tvs(g)is the minimum value of the largest label k over all such irregular assignment. in this paper, we study the to...

Let F2k,k2 consist of all simple graphs on 2k vertices and k2 edges. For a simple graph G and a positive integer λ, let PG(λ) denote the number of proper vertex colorings of G in at most λ colors, and let f(2k, k2, λ) = max{PG(λ) : G ∈ F2k,k2}. We prove that f(2k, k2, 3) = PKk,k(3) and Kk,k is the only extremal graph. We also prove that f(2k, k2, 4) = (6 + o(1))4k as k →∞.
