Born small, die young: Intrinsic, size-selective mortality in marine larval fish
(
Nature Publishing Group
, 2015 , Article)
Mortality during the early stages is a major cause of the natural variations in the size and recruitment strength of marine fish populations. In this study, the relation between the size-at-hatch and early survival was ...
An energy-efficient distributed clustering algorithm for heterogeneous WSNs
(
Springer International Publishing
, 2015 , Article)
Wireless sensor networks (WSNs) were envisaged to become the fabric of our environment and society. However, they are yet unable to surmount many operational challenges such as limited network lifetime, which strangle their ...

(
Springer Berlin Heidelberg
, 2015 , Article)
We investigated the horizontal and vertical distribution of heavy metals (Hg, Pb, Zn, Cu, Cd, As, Ni, and Cr) in soils in the water source protection zone for Shanghai to study the origins of these metals, their connections ...
Carboxybetaine Modified Interface for Electrochemical Glycoprofiling of Antibodies Isolated from Human Serum
(
American Chemical Society
, 2015 , Article)
Impedimetric lectin biosensors capable of recognizing two different carbohydrates (galactose and sialic acid) in glycans attached to antibodies isolated from human serum were prepared. The first step entailed the modification ...

Amman Stock Exchange (ASE) for a full sample and three sub-periods of that spanning
period 2000-2012. The research uses statistical ...
Opposing calcium-dependent signalling pathways control skeletal muscle differentiation by regulating a chromatin remodelling enzyme
(
Nature Publishing Group
, 2015 , Article)
Calcium signalling is important for differentiation-dependent gene expression, but is also involved in other cellular functions. Therefore, mechanisms must exist to distinguish calcium signalling relevant to differentiation. ...
Effects of salinity and ascorbic acid on growth, water status and antioxidant system in a perennial halophyte
(
Oxford University Press
, 2015 , Article)
Salinity causes oxidative stress in plants by enhancing production of reactive oxygen species, so that an efficient antioxidant system, of which ascorbic acid (AsA) is a key component, is an essential requirement of ...
