Molecular and biochemical survey of acaricide resistance mechanisms in larvae from Mexican strains of the southern cattle tick, Boophilus microplus.
We examined the larvae of several organophosphate and pyrethroid-resistant Mexican strains of Boophilus microplus using biochemical and molecular tests to investigate the mechanisms conferring… Expand

We have developed a series of emulsion polymerization recipes for the synthesis of highly charged, monodisperse polystyrene colloids of diameters between 100-400 nm. These spherical colloidal… Expand
A common image processing framework for 2D barcode reading
The present work describes an image processing system able to locate, segment and decode the most common 2D symbol used in bar code applications. Expand
Photic Regulation of mt1 Melatonin Receptors in the Siberian Hamster Pars Tuberalis and Suprachiasmatic Nuclei: Involvement of the Circadian Clock and Intergeniculate Leaflet

In the Siberian hamster suprachiasmatic nuclei and pars tuberalis of the pituitary, high affinity mt1 melatonin receptors are present. We have previously shown that night applied light pulse induced… Expand
Upper k-Alliances in Graphs
A nonempty set S ⊆ V is a defensive k-alliance in Γ = (V, E), k ∈ [−Δ,Δ] ∩ Z, if for every v ∈ S, δS(v) ≥ δS̄(v) + k. An defensive kalliance S is called critical if no proper subset of S is an… Expand
Kondo insulators modeled by the one-dimensional Anderson lattice: A numerical-renormalization-group study.
In order to better understand Kondo insulators, we have studied both the symmetric and asymmetric Anderson lattices at half filling in one dimension using the density-matrix formulation of the… Expand
Phase diagram of the one-dimensional Anderson lattice.
We map out the phase diagram of the one-dimensional Anderson lattice by studying the ground-state magnetization as a function of band filling using the density matrix renormalization group technique.… Expand
Direct evidence of a radical mechanism in the addition reaction of iododifluoroesters to olefins by spin trapping
We present EPR analysis of the reaction of ethyl iododifluoroacetate with 1-tetradecene in the presence of Zn + NiCl2 x 6H2O, confirming the mechanistic studies that provide evidence of a single… Expand
Quasiperiodic and chaotic behavior due to competition between spatial and temporal modes in long Josephson junctions.
We present numerical simulations of long Josephson junctions in the presence of an rf bias and an applied magnetic field, which we model with a sine-Gordon-like equation. We focus our attention on… Expand
