High-density mapping of quantitative trait loci for grain-weight and spikelet number in rice.

Rice (New York, N.Y.)

Kim DM, Lee HS, Kwon SJ, Fabreag ME, Kang JW, Yun YT, Chung CT, Ahn SN.
PMID: 26055996
Rice (N Y). 2014 Dec;7(1):14. doi: 10.1186/s12284-014-0014-5. Epub 2014 Aug 19.

BACKGROUND: High grain yield is one of the most important traits requiring improvement in rice breeding programs. Consequently, the genetic basis of spikelets per panicle (SPP) and grain weight (TGW) have received much research focus because of their importance...

The short-term memory performance of a group of younger adults, for whom English was a second language (young EL2 listeners), was compared to that of younger and older adults for whom English was their first language (EL1 listeners). To-be-remembered...

Plasmonic gold nanoparticles for ZnO-nanotube photoanodes in dye-sensitized solar cell application.

Nanoscale

Abd-Ellah M, Moghimi N, Zhang L, Thomas JP, McGillivray D, Srivastava S, Leung KT.
PMID: 26690257
Nanoscale. 2016 Jan 21;8(3):1658-64. doi: 10.1039/c5nr08029k.

Surface modification of nanostructured metal oxides with metal nanoparticles has been extensively used to enhance their nanoscale properties. The unique properties of metal nanoparticles associated with their controllable dimensions allow these metal nanoparticles to be precisely engineered for many...

Low-field Switching Four-state Nonvolatile Memory Based on Multiferroic Tunnel Junctions.

Scientific reports

Yau HM, Yan ZB, Chan NY, Au K, Wong CM, Leung CW, Zhang FY, Gao XS, Dai JY.
PMID: 26239505
Sci Rep. 2015 Aug 04;5:12826. doi: 10.1038/srep12826.

Multiferroic tunneling junction based four-state non-volatile memories are very promising for future memory industry since this kind of memories hold the advantages of not only the higher density by scaling down memory cell but also the function of magnetically...

Convergence analyses on on-line weight noise injection-based training algorithms for MLPs.

IEEE transactions on neural networks and learning systems

Sum J, Leung CS, Ho K.
PMID: 24808076
IEEE Trans Neural Netw Learn Syst. 2012 Nov;23(11):1827-40. doi: 10.1109/TNNLS.2012.2210243.

Injecting weight noise during training is a simple technique that has been proposed for almost two decades. However, little is known about its convergence behavior. This paper studies the convergence of two weight noise injection-based training algorithms, multiplicative weight...
