OBJECTIVE Compare the quality of life (QOL) of youth living with visible facial differences (FDs) with youth living with a visible nonfacial difference (i.e., mobility limitations), an invisible difference (i.e., attention deficit/hyperactivity disorder), or no known difference. DESIGN An observational study of perceived QOL among adolescents with FDs (n = 56), adolescents with no diagnosed c...

When communication in sensor networks occurs over wireless links, confidential information about the communication patterns between sensor nodes could be leaked even when encryption is used to protect the actual contents of the messages. The communication patterns, which often reveal higher volumes of traffic near the sink, could allow an attacker to identify the vicinity of the sink node. With...

[1] Recent upward revisions in key sink/source terms for fixed nitrogen (N) in the oceans imply a short residence time and strong negative feedbacks involving denitrification and N fixation to prevent large swings in the ocean N inventory over timescales of a few centuries. We tested the strength of these feedbacks in a global biogeochemical elemental cycling (BEC) ocean model that includes wat...

We examine the relative importance of processes that underlie plant population abundance and distribution. Two opposing views dominate the field. One posits that the ability to establish at a site is determined by the availability of suitable microsites (establishment limitation), while the second asserts that recruitment is limited by the availability of seeds (seed limitation). An underlying ...

Abstract Background Being a promising tropical woody oilseed crop, the evergreen and recurrent plants of Sacha Inchi ( Plukenetia volubilis L.) has complex phenology source–sink interactions. Carbon manipulations with control two treatments (reduce source, ca. 10% mature leaf pruning; reduce sink, fruitlet thinning) were conducted on 2.5-year-old field-grown P. plantation during early-wet seaso...

Stem diameter growth of g-year-old sweetgum (Liquidambar styraciflua) trees was measured and related with the activity of sucrose-synthase (SS), an enzyme that has been associated with carbon sink strength in agriculture crops and tree seedlings. In 1984, 1-O sweetgum seedlings were transplanted to control plots and plots amended with sewage sludge or nitrogen and phosphorus fertilizer. After 8...

The aim of this study was to use meta-analysis to identify the enteric methane (CH4) mitigation strategy that reduced CH4 emission without lowering production. To this end, a database initially developed was updated, compiling data from 61 publications (233 experiments) for various observations in dairy cattle on effects of hydrogen sink (H-sink), ionophore, lipid and conc...

MAIZE grain yield is shaped by source-sink relationships during filling. Such relations are driven complex metabolic changes, responsive to N availability and not fully understood. Here, the impact of limited sufficient fertilization on interconversions in ear leaf a new maize field-grown hybrid (Tzi8 × Mo17) its critical transition from assimilation remobilization were chronologically investig...
