1. Introduction Recent advances in photonic cross-connect (XC) systems and their associated switch fabrics are remarkable [1], [2]. Some photonic switches are reported to allow for an abundant switching capability beyond 1000×1000 at the optical path (OP) level. However, the rationale for such large-scale switches has not yet been proven from the viewpoint of network management or operation. Wa...
Proof. ‖∇F (δ)‖∞ ≤ guarantees that μ = μ(δ) are -consistent in the sense that |μi(xi) − μc(xi)| ≤ for all c, i ∈ c and xi. Algorithm 1 maps any such -consistent μ to locally consistent marginals μ̃ such that |μi(xi)− μ̃i(xi)| ≤ 3 Nmax, |μc(xc)− μ̃c(xc)| ≤ 2 N max, (3) for all i, xi, c, and xc, where Nmax = max{maxiNi,maxcNc}. In other words, ‖μ− μ̃‖∞ ≤ K . This can be easily derived from the update...
We suggest a more nuanced view of the merit and utility of generalized gradient approximations (GGAs) for the noninteracting kinetic energy (KE) than the critique of Xia and Carter (XC) [Phys. Rev. B 91, 045124 (2015)]. Specifically, the multiple valuedness of the Pauli term enhancement factor (denoted G[n] by XC) with respect to the inhomogeneity variable s can be excluded by enforcement of a ...
C Maximum likelihood estimation C.1 Building the likelihoood function Let Θ = (Θ1; Θ2) = (σ , σ η, σ u, π; β1, λ1, β2, λ2, φ) be the vector of parameters. Let X = (x1,s,t, x2,s,t, r1,s,t, r2,s,t) be the vector of observables, with r2 = p2− p1 and r1 = p1. Let 1(x) be an indicator variable equal to 1 if the event x has occured, and 0 otherwise. Let g(x) be the standard normal PDF and G(x) the st...
Sepsis is the host's deleterious systemic inflammatory response to microbial infections. Here we report an essential role for the estrogen sulfotransferase (EST or SULT1E1), a conjugating enzyme that sulfonates and deactivates estrogens, in sepsis response. Both the cecal ligation and puncture (CLP) and lipopolysacharide (LPS) models of sepsis induce the expression of EST and compromise the act...
AIMS Phosphoinositide 3-kinases (PI3Ks) relay growth factor signaling and mediate cytoprotection and cell growth. The cystine/glutamate antiporter system xc(-) imports cystine while exporting glutamate, thereby promoting glutathione synthesis while increasing extracellular cerebral glutamate. The aim of this study was to analyze the pathway through which growth factor and PI3K signaling induce ...
This paper sets out our observations, modeling results, and conclusions regarding a novel organizational form applied variously as “extreme collaboration” (XC) or “radical collocation.” XC teams are cross-functional, co-located groups enabled with high-performance computer modeling and simulation tools, large interactive graphic displays, a mature shared generic project model that the design te...
Cold environments are common throughout the Galaxy. We are conducting a series of experiments designed to probe the low-temperature limits for growth in selected methanogenic and halophilic Archaea. This paper presents initial results for two mesophiles, a methanogen, Methanosarcina acetivorans, and a halophile, Halobacterium sp. NRC-1, and for two Antarctic coldadapted Archaea, a methanogen, M...
