A cross sectional epidemiological study was carried out to investigate the validity ofpersistent nocturnal cough (PNC) as an independent marker ofchildhood asthma. A screening questionnaire on respiratory symptoms was applied to 4003 children attending primary schools in Aberdeen, after which 799 symptomatic children and a random selection of 229 asymptomatic children were invited to attend for...

Direct application of network coding at the physical layer physical layer network coding (PNC) is a promising technique for two-way relay wireless networks. In a two-way relay network, relay nodes are used to relay two-way information flows between pairs of end nodes. This paper proposes a precise definition for PNC. Specifically, in PNC, a relay node does not decode the source information from...

OBJECTIVE The aim of this study was to explore the reasons why pregnant women do not seek prenatal care (PNC). METHODOLOGY The ethnographic method was used in a low-income Brazilian community. Ethnographic interviews were performed with 11 postpartum women who did not seek PNC in their last pregnancy. RESULTS The cultural sub-themes used to express reasons for not seeking PNC included: "I f...

We resolve the question of optimality for a wellstudied packetized implementation of random linear network coding, called PNC. In PNC, in contrast to the classical memoryless setting, nodes store received information in memory to later produce coded packets that reflect this information. PNC is known to achieve order optimal stopping times for the manyto-all multicast problem in many settings. ...

BACKGROUND Globally postnatal care (PNC) of the newborn is being promoted as a strategy to reduce neonatal deaths, yet few studies have looked at associations between early PNC and neonatal outcomes in sub-Saharan Africa. In this study we look at the associations of PNC provided on day 1 and by day 7 of life by type of provider - skilled (doctor, midwife or nurse or unskilled (traditional birth...

The perinucleolar compartment (PNC) is a unique nuclear structure preferentially localized at the periphery of the nucleolus. Several small RNAs transcribed by RNA polymerase III (e.g., the Y RNAs, MRP RNA, and RNase P H1 RNA) and the polypyrimidine tract binding protein (PTB; hnRNP I) have thus far been identified in the PNC (Ghetti, A., S. PinolRoma, W.M. Michael, C. Morandi, and G. Dreyfuss....

The concept of physical-layer network coding (PNC) was proposed in 2006 for application in wireless networks. Since then it has developed into a subfield of network coding with wide followings. The basic idea of PNC is to exploit the network coding operation that occurs naturally when electromagnetic (EM) waves are superimposed on one another. This simple idea turns out to have profound and fun...

The perinucleolar compartment (PNC) is a unique nuclear structure localized at the periphery of the nucleolus. Several small RNAs transcribed by RNA polymerase III and two hnRNP proteins have been localized in the PNC (Ghetti, A., S. Piñol-Roma, W.M. Michael, C. Morandi, and G. Dreyfuss. 1992. Nucleic Acids Res. 20:3671-3678; Matera, A.G., M.R. Frey, K. Margelot, and S.L. Wolin. 1995. J. Cell B...

Background Bangladesh achieved Millennium Development Goal 4, a two thirds reduction in under-five mortality from 1990 to 2015. However neonatal mortality remains high, and neonatal deaths now account for 62% of under-five deaths in Bangladesh. The objective of this paper is to understand which newborns in Bangladesh are receiving postnatal care (PNC), a set of interventions with the potential ...
