This paper presents experimental results of detecting multipath using a recently proposed parameter, early late phase (ELP). The paper shows that positioning error caused by multipath can be reduced by excluding the satellites detected as experiencing multipath from the navigation solution, except where the exclusion causes a significant increase in dilution of precision. Performance of this EL...

The liver is a multifunctional organ responsible for steroid hormones catabolism. Thus, the enzymes responsible for steroid catabolism are located in the liver, including the steroid 5alpha-Reductase (5alpha-R) (EC 1.3.99.5) which catalyzes the conversion of compounds with Delta(4,5) double bonds such as testosterone (T) into their respective reduced derivatives such as dihydrotestosterone (DHT...
Previous work suggested that the underlying mechanisms by which the Streptococcus mutans ClpXP protease affects virulence traits are associated with accumulation of two orthologues of the Spx regulator, named SpxA and SpxB. Here, a thorough characterization of strains lacking the spx genes (Delta spxA, Delta spxB, and Delta spxA Delta spxB) revealed that Spx, indeed, participates in the regulat...
The joining of single-stranded breaks in double-stranded DNA is an essential step in many important processes such as DNA replication, DNA repair, and genetic recombination. Several data implicate a role for DNA ligase I in DNA replication, probably coordinated by the action of other enzymes and proteins. Since both DNA polymerases delta and epsilon show multiple functions in different DNA tran...
Speech production is essentially a nonlinear dynamic process. Motivated by ideas in dynamic system research, this paper seeks to recast the speech representation problem (frontend) as an attempt to reconstruct the phase space of the production process, or articulatory configurations. In particular, we point out that the use of the delta and double delta features, common in current ASR (Automati...
Opioid receptors belong to the G protein coupled receptor family. They modulate brain function at all levels of neural integration and therefore impact on autonomous, sensory, emotional and cognitive processing. In vivo functional interaction between mu and delta opioid receptors are known to take place though it is still debated whether interactions occur at circuitry, cellular or molecular le...
Increased numbers of T cell receptor (TCR)-gamma/delta cells have been observed in animal models of influenza and sendai virus infections, as well as in patients infected with human immunodeficiency virus and herpes simplex virus type 1 (HSV-1). However, a direct role for TCR-gamma/delta cells in protective immunity for pathogenic viral infection has not been demonstrated. To define the role of...
The mammalian rod photoreceptor phosphodiesterase (PDE6) holoenzyme is isolated in both a membrane-associated and a soluble form. Membrane binding is a consequence of prenylation of PDE6 catalytic subunits, whereas soluble PDE6 is purified with a 17-kDa prenyl-binding protein (PDEdelta) tightly bound. This protein, here termed PrBP/delta, has been hypothesized to reduce activation of PDE6 by tr...
