Mutants of the Drosophila dunce (dnc) and rutabaga (rut) genes, which encode a cAMP-specific phosphodiesterase and a calcium/calmodulin-responsive adenylyl cyclase, respectively, are deficient in short-term memory. Altered synaptic plasticity has been demonstrated at neuromuscular junctions in these mutants, but little is known about how their central neurons are affected. We examined this prob...

The survival of young children with sickle cell disease (SCD) has improved, but less is known about older children and adolescents. We studied the Dallas Newborn Cohort (DNC) to estimate contemporary 18-year survival for newborns with SCD and document changes in the causes and ages of death over time. We also explored whether improvements in the quality of medical care were temporally associate...

In this work, we consider a typical three-node, two-way relaying network (TWRN) over fading channels. The aim is to minimize the entire system energy usage for a TWRN in the long run, while satisfying the required average symmetric exchange rate between the two source nodes. To this end, the energy usage of the physical-layer network coding (PNC) or the superposition coding based digital networ...

Vector Product Format (VPF) based databases store geographical data in a relational framework, where individual VPF files are arranged hierarchically in a directory tree structure. Access and update of the VPF data can become difficult due to fragmentation of data among multiple tables. This paper presents an object-oriented model for the management of a VPF database, which provides easy access...

Despite recent advances in cancer medication, malignant tumors continue to be the second leading cause of death worldwide. Furthermore, introducing a therapeutic compound with low-side effects as well as low-price for consumers is controversial. Recent efforts have been focusing on traditional medicines as a rich source of herbal agents. Curcumin, the major turmeric phytochemical, has been wide...

This paper examines the prospects for the successful implementation of a distributed national collec-tion policy in the United Kingdom. It does so by tracing the Australian experience with the implemen-tation of a similar scheme, the Distributed National Collection (DNC), during the late 1980s and1990s. The rationale for the introduction of the DNC is explained, and some of the reas...

D annual expenditures on public relations exceeding $19.42 billion, U.S. businesses lack practical guidance about the effectiveness of publicity in mass media. Here, we assemble a rich and novel data set to gauge the impact of news reports on consumer sign-ups with the U.S. Do Not Call (DNC) Registry. Using multiple identification strategies, we found robust evidence that news reports increased...

The Dual Nonlinear Correlation (DNC) model implemented by an optoelectronic joint transform correlator (JTC) (Millán et al., Dual Nonlinear Correlation in Optical Pattern Recognition I, Óptica Pura y Aplicada 38, núm. 2, 75-83, 2005) provides a pattern recognition system with adjustable discrimination capability (DC). By varying the values of two real parameters (L and M) in the DNC we obtain e...

The purpose of this study was to determine the effect of PEGylation on the interaction of poly(amidoamine) (PAMAM) dendrimer nanocarriers (DNCs) with in vitro and in vivo models of the pulmonary epithelium. Generation-3 PAMAM dendrimers with varying surface densities of PEG 1000 Da were synthesized and characterized. The results revealed that the apical to basolateral transport of DNCs across p...
