A revised Bayesian algorithm for estimating surface rain rate, convective rain proportion, and latent heating profiles from satellite-borne passive microwave radiometer observations over ocean backgrounds is described. The algorithm searches a large database of cloud-radiative model simulations to find cloud profiles that are radiatively consistent with a(More)
The variable rule program is one of the predominant data analysis tools used in sociolinguistics, employed successfully for over three decades to quantitatively assess the influence of multiple factors on linguistic variables. However, its most popular current version, GoldVarb, lacks flexibility and also isolates its users from the wider community of(More)
Protein kinase C (PKC) regulation of l-ascorbic acid transport mediated by the Na+/ascorbic acid transporters, hSVCT1 and hSVCT2, expressed in COS-1 cells was studied using recombinant carboxyl-terminal V5 epitope-tagged forms of the transporters. The PKC activator phorbol 12-myristate 13-acetate (PMA) caused a time-dependent and concentration-dependent(More)

Effects of sinusoidal 60-Hz electric currents on DNA synthesis in rat osteosarcoma cell (ROS 17/2.8) in culture were investigated using agar electrodes. This exposure system eliminates electrochemical effects at electrode surfaces, minimizes the contribution of magnetic fields and produces no detectable temperature changes (less than +/- 0.1 degrees C) at(More)
A mouse monoclonal antibody raised against rat osteosarcoma alkaline phosphatase (AP) was covalently coupled to protein A-Sepharose and used to purify this enzyme from preparations of rat osteosarcoma, calvaria, kidney, and placenta in a single-step procedure. The tissue-specific isoenzymes purified in this manner showed identity in the immunodiffusion(More)
Cowpea-type Rhizobium sp. strain 32H1 and Rhizobium japonicum USDA 26 and 110 grown on a glutamate-mannitol-gluconate agar medium showed increases in the number of pleomorphic cells coincident with their acetylene-reducing activity. Pleomorphs appeared to be inhibited in growth nonuniformly, because acetylene-reducing cultures were mixtures of rod, branched(More)
An increasing number of sociolinguists are using mixed effects models, models which allow for the inclusion of both fixed and random predicting variables. In most analyses, random effect intercepts are treated as a by-product of the model; they are viewed simply as a way to fit a more accurate model. This paper presents additional uses for random effect(More)
