During the past few years, the generalized additive model (GAM) has become a standard tool for epidemiologic analysis exploring the effect of air pollution on population health. Recently, the use of the GAM has been extended from time-series data to spatial data. Still more recently, it has been suggested that the use of GAMs to analyze time-series data results in air pollution risk estimates b...
Experimental investigations has elucidated on the complex dynamics of the low to high (L-H) plasma confinement mode transition. Evidence of interactions between the the turbulence driven E⃗ × B⃗ zonal flow oscillation or Geodesic Acoustic Mode (GAM) [1], turbulence and the mean equilibrium flows during this transition was found. Furthermore, periodic modulation of flow and turbulence level with t...
BACKGROUND Global acute malnutrition (GAM) is the sum of moderate acute malnutrition (MAM) and severe acute malnutrition (SAM). The use of different foods and protocols for MAM and SAM treatment can be cumbersome in emergency settings. OBJECTIVE Our objective was to determine the recovery and coverage rates for GAM of an integrated protocol with a single food product, ready-to-use therapeutic...
where x ∈ R denotes a sample and xj ∈ R denotes the j-th explanatory variable for each j ∈ [1, p] , {j ∈ N|1 ≤ j ≤ p}. This was first proposed by Hastie and Tibshirani (1987) and is known as a generalized additive model (GAM). In this paper, we call fj(·) a weight function and f(·) a GAM predictor. This not only includes linear predictors but also captures nonlinear relationships between explan...
Localization of mRNAs is currently thought to be partially responsible for molecular sorting to specific compartments within the cell. In mammalian cells the best-studied example is the beta-actin mRNA that is localized to the cell processes, and its localization is necessary in migratory responses of cells. It is reasonable to assume that mRNA localization within cells is coupled to transmembr...
Escherichia coli strains bearing plasmids expressing phage P22 anti-RecBCD functions abc1 and abc2 were tested for the presence of recBC-like phenotypes. Abc2 induces moderate sensitivity to UV light in wild-type and recD mutant strains but severely sensitizes both recF and recJ mutants. Abc1 has little effect on UV sensitivity in wild-type or recF or recJ mutant hosts but increases the sensiti...
Gallium is antiproliferative to many types of cancer, due primarily to its ability to act as a non-functional mimic of ferric iron (Fe(3+)). Because Fe(3+) is needed for ribonucleotide reductase activity--and thus DNA synthesis--gallium can inhibit DNA production and cell division. Diagnostic gallium scans have shown that hepatocellular carcinoma (HCC) is commonly avid for gallium. Furthermore,...
We report the identification and functional analysis of nine genes from Gram-positive and Gram-negative bacteria and their phages that are similar to lambda (lambda) bet or Escherichia coli recT. Beta and RecT are single-strand DNA annealing proteins, referred to here as recombinases. Each of the nine other genes when expressed in E. coli carries out oligonucleotide-mediated recombination. To o...
Generalized additive models (GAMs) are a generalization of generalized linear models (GLMs) and constitute a powerful technique which has successfully proven its ability to capture nonlinear relationships between explanatory variables and a response variable in many domains. In this paper, GAMs are proposed as base classifiers for ensemble learning. Three alternative ensemble strategies for bin...
In the Large Helical Device (LHD), a reversed magnetic shear (RS) configuration having non-monotonic rotational transform profile was formed by intense counter neutral beam (NB) current drive. In the RS configuration helical plasma, the reversed shear Alfvén eigenmode (RSAE) with n=1 toroidal mode number was identified together with energetic-ion-driven geodesic acoustic mode (GAM) with n=0. Te...
