A 167 base pair DNA cassette has been constructed to facilitate the detection and purification of recombinunt proteins. This cassette, kfc, cncodcs three distinct peptide units: a phosphorylation site for (he CAMP-depcndeni protein base (PKA), called hemptidc, a factor Xa cleavage site, and a calmodulin-binding peptide. Expressed kfc fusio? proteins can be purified from bacterial lysates in one...

A localized Delaunay triangulation owns the following interesting properties for sensor and wireless ad hoc networks: it can be built with localized information, the communication cost imposed by control information is limited, and it supports geographical routing algorithms that offer guaranteed convergence. This paper presents two localized algorithms, FLDT1 and FLDT2, that build a graph call...

Coherent Hemodynamics Spectroscopy (CHS) is a technique based on inducing cerebral hemodynamic oscillations at multiple frequencies, measuring them with near-infrared spectroscopy (NIRS), and analyzing them with a hemodynamic model to obtain physiological information such as blood transit times in the microvasculature and the autoregulation cutoff frequency. We have previously demonstrated that...

A single-step protein affinity purification protocol using Aspergillus nidulans is described. Detailed protocols for cell breakage, affinity purification, and depending on the application, methods for protein release from affinity beads are provided. Examples defining the utility of the approaches, which should be widely applicable, are included.

1.1 Simple derivation of GBLUP Models for genomic selection are abundant. However, most of them rely (yet not all; [1] ) in a hierarchical formulation in which SNP markers (or haplotypes) have additive effect on the trait of interest [2]. We will focus here in models including biallelic SNP markers. Thus, n markers will have n effects, a1 ... an. Although markers have 2 alleles, a single effect...

The structure of satisfiability problems is used to improve search algorithms for quantum computers and reduce their required coherence times by using only a single coherent evaluation of problem properties. The structure of random k-SAT allows determining the asymptotic average behavior of these algorithms, showing they improve on quantum algorithms, such as amplitude amplification, that ignor...

The motor protein Kinesin-1 drives intracellular transport along microtubules, with each of its two motor domains taking 16-nm steps in a hand-over-hand fashion. The way in which a single-motor domain moves during a step is unknown. Here, we use Förster resonance energy transfer (FRET) between fluorescent labels on both motor domains of a single kinesin. This approach allows us to resolve the r...

The use of vertical-cavity surface-emitting laser (VCSEL) arrays for implementation of incoherent source superresolution is presented. The method uses an interferometer setup to obtain superresolution in a single step. The novelty of the method relies on the use of a VCSEL array as the light source, which provides a set of coherent sources which are mutually incoherent. The technique accomplish...

All the liposome preparation protocols, which involve drug encapsulation are multi-step processes, i.e. they consist of one or several steps of preparation and homogenization. The conditions of converting all lipids into vesicles smaller than 200 nm were determined by replacing ultrasonication with mechanical stirring of the buffer and solution of lipids in a low-boiling point organic solvent o...

This paper addresses recommendation diversification. Existing diversification methods have a difficulty in dealing with the accuracy-diversity tradeoff. We propose a novel method to simultaneously optimize the user preference and diversity of k -items to be recommended.
