Activated macrophages are a critical component of our antimicrobial armamentarium. Unfortunately, the lipid mediators and free radicals that these cells produce are not only toxic to potential pathogens, but also to the host. Thus the modulation of these activities can mitigate an overzealous immune response and thereby prevent host cell injury. Two families of receptor tyrosine kinases (RTK) i...

Abstract Docks are a widespread problem in grassland, necessitating novel management solutions as pesticides become increasingly regulated. The objective was to investigate the role of soil test Potassium (K) concentrations (Morgan's solution; Na acetate + acetic acid, pH 4.8; STK) on competitiveness docks grassland. experimental site (52°21 N, 7°18 W) reseeded with perennial ryegrass October 2...

Let C+ := {s ∈ C | Re(s) ≥ 0} and let A denote the ring A = ( s(∈ C+) 7→ b fa(s) + ∞ X k=0 fke −stk ̨̨̨̨ fa ∈ L(0,∞), (fk)k≥0 ∈ `, 0 = t0 < t1 < t2 < . . . ) equipped with pointwise operations. (Here b· denotes the Laplace transform.) It is shown that the ring A is not coherent, answering a question of Alban Quadrat [6, p. 30]. In fact, we present two principal ideals in the domain A whose intersec...

The Clustering project is a part of the STK++ library (Iovleff 2012) that can be accessed from R (R Development Core Team 2013) using the MixAll package. It is possible to cluster Gaussian, gamma, categorical, Poisson, kernel mixture models or a combination of these models in case of mixed data. Moreover, if there is missing values in the original data set, these missing values will be imputed ...

Abstract: Given two assets Sand B with price processes two correlated geometric Brownian motions S. = (Stk::o, B. = (Sdt~o and a bond B. Suppose that we can only observe B. and can only trade in B. and B or equivalently buy options on B. at time T = O. Suppose further that we want to hedge an arbitrary binary option H depending on ST; i.e. H = l{sTEA}' Under these conditions it is shown that th...

To improve short-term particulate matter (PM) forecasts in South Korea, the initial distribution of PM composition, particularly over the upwind regions, is primarily important. To prepare the initial PM composition, the aerosol optical depth (AOD) data retrieved from a geostationary equatorial orbit (GEO) satellite sensor, GOCI (Geostationary Ocean Color Imager) which covers a part of Northeas...
