Precise particle tracking against a complicated background: polynomial fitting with Gaussian weight.
We present a new particle tracking software algorithm designed to accurately track the motion of low-contrast particles against a background with large variations in light levels. The method is basedExpand

A Novel Alkaliphilic Bacillus Esterase Belongs to the 13th Bacterial Lipolytic Enzyme Family
Background Microbial derived lipolytic hydrolysts are an important class of biocatalysts because of their huge abundance and ability to display bioactivities under extreme conditions. In spite ofExpand

Adsorption of Dodecyl Sulfate Surfactants with Monovalent Metal Counterions at the Air-Water Interface Studied by Neutron Reflection and Surface Tension
Abstract Neutron reflection and surface tension have been used to study the adsorption at the air-water interface of the dodecyl sulfates of the alkali metals (MDS). The critical micelleExpand

THE CONFORMATIONAL STRUCTURE OF BOVINE SERUM ALBUMIN LAYERS ADSORBED AT THE SILICA-WATER INTERFACE
The adsorption of bovine serum albumin (BSA) at the hydrophilic silica−water interface has been studied using specular neutron reflection. The measurements were made over the concentration range fromExpand

Latherin: A Surfactant Protein of Horse Sweat and Saliva
Horses are unusual in producing protein-rich sweat for thermoregulation, a major component of which is latherin, a highly surface-active, non-glycosylated protein. The amino acid sequence ofExpand

The metrics of surface adsorbed small molecules on the Young's fringe dual-slab waveguide interferometer
A method for analysing thin films using a dual-waveguide interferometric technique is described. Alternate dual polarization addressing of the interferometer sensor using a ferroelectric liquidExpand

Effect of pH on the Adsorption of Bovine Serum Albumin at the Silica/Water Interface Studied by Neutron Reflection
In a previous study of BSA adsorption onto the hydrophilic silica/water interface using neutron reflection, we examined the concentration dependence of the surface excess of BSA at a pH close to itsExpand

Adsorption of frog foam nest proteins at the air-water interface.
The surfactant properties of aqueous protein mixtures (ranaspumins) from the foam nests of the tropical frog Physalaemus pustulosus have been investigated by surface tension, two-photon excitationExpand

Solution Behavior and Activity of a Halophilic Esterase under High Salt Concentration
Background Halophiles are extremophiles that thrive in environments with very high concentrations of salt. Although the salt reliance and physiology of these extremophiles have been widelyExpand

Ranaspumin-2: structure and function of a surfactant protein from the foam nests of a tropical frog.
Ranaspumin-2 (Rsn-2) is a monomeric, 11 kDa surfactant protein identified as one of the major foam nest components of the túngara frog (Engystomops pustulosus), with an amino acid sequence unlike anyExpand
