Laboratory findings: structure, validity and significance for medical cognitive processes.

European journal of clinical chemistry and clinical biochemistry : journal of the Forum of European Clinical Chemistry Societies

Büttner J.
PMID: 1954305
Eur J Clin Chem Clin Biochem. 1991 Aug;29(8):507-19.

Modern medicine employs laboratory findings to a great extent in medical cognitive and decision processes. As supposedly "hard" data, the value of such findings is frequently incorrectly assessed. So far, no comprehensive general theory of laboratory findings has been...

Optimal proportional relation between laser power and pulse number for the fabrication of surface-microstructured silicon.

Applied optics

Peng Y, Wen Y, Zhang D, Luo S, Chen L, Zhu Y.
PMID: 21857699
Appl Opt. 2011 Aug 20;50(24):4765-8. doi: 10.1364/AO.50.004765.

We experimentally demonstrate that, under the same laser fluence, there exists an optimal proportional relation between the laser power and pulse number for the fabrication of surface-microstructured silicon. During this fabrication process, the pulse number represents the interaction time...

Graphene-assisted ultra-compact polarization splitter and rotator with an extended bandwidth.

Scientific reports

Zhang T, Ke X, Yin X, Chen L, Li X.
PMID: 28939811
Sci Rep. 2017 Sep 22;7(1):12169. doi: 10.1038/s41598-017-12536-8.

The high refraction-index contrast between silicon and the surrounding cladding makes silicon-on-insulator devices highly polarization-dependent. However, it is greatly desirable for many applications to address the issue of polarization dependence in silicon photonics. Here, a novel ultra-compact polarization splitter...

Rationale and design of ASSAF-K (A study of the safety and efficacy of anticoagulant therapy in the treatment of atrial fibrillation in Kanagawa).

Journal of arrhythmia

Hatori Y, Sakai H, Kunishima T, Hatori N, Chen L, Ishigami T, Satoh N.
PMID: 28416976
J Arrhythm. 2017 Apr;33(2):111-116. doi: 10.1016/j.joa.2016.07.008. Epub 2016 Aug 23.

BACKGROUND: Atrial fibrillation (AF) is one of the most prevalent cardiac arrhythmias associated with substantially increased risks of ischemic stroke and thromboembolism. Oral anticoagulants (OACs) are the cornerstone of AF management and effectively prevent AF-related stroke. As new non-vitamin...

Bottom-up, hard template and scalable approaches toward designing nanostructured Li2S for high performance lithium sulfur batteries.

Nanoscale

Chen L, Liu Y, Dietz-Rago N, Shaw LL.
PMID: 26420373
Nanoscale. 2015 Nov 21;7(43):18071-80. doi: 10.1039/c5nr04478b.

Li2S with a high theoretical capacity of 1166 mA h g(-1) and the capability to pair with lithium free anodes has drawn much attention for lithium sulfur (Li-S) battery applications. However, the fast battery decay and the low capacity...

Pi-Extended Diindole-Fused Azapentacenone: Synthesis, Characterization, and Photophysical and Lithium-Storage Properties.

Chemistry, an Asian journal

Zhao J, Li R, Ai W, Dong D, Li J, Chen L, Xie L, Yu T, Huang W.
PMID: 26717256
Chem Asian J. 2016 May 06;11(9):1382-7. doi: 10.1002/asia.201501366. Epub 2016 Jan 21.

Pi-extended polyaromatics tend to exhibit improved electronic properties with respect to the intrinsic structures. Herein, the rational design of a π-extended diindole-fused diazapentacenone (IP), with a nine-ring-fused core, obtained by applying an intramolecular Friedel-Crafts diacylation synthetic routine, is reported....

Physical Activity and Risk of Lung Cancer: A Meta-analysis.

Clinical journal of sport medicine : official journal of the Canadian Academy of Sport Medicine

Zhong S, Ma T, Chen L, Chen W, Lv M, Zhang X, Zhao J.
PMID: 26213983
Clin J Sport Med. 2016 May;26(3):173-81. doi: 10.1097/JSM.0000000000000219.

OBJECTIVE: Previous studies concerning the association between physical activity (PA) and risk of lung cancer yielded mixed results. We investigated the association by performing a meta-analysis.DATA SOURCES: Relevant studies were identified by searching PubMed and EMBASE to January 2014....

Genetic Characterization of Continually Evolving Highly Pathogenic H5N6 Influenza Viruses in China, 2012-2016.

Frontiers in microbiology

Li M, Zhao N, Luo J, Li Y, Chen L, Ma J, Zhao L, Yuan G, Wang C, Wang Y, Liu Y, He H.
PMID: 28293218
Front Microbiol. 2017 Feb 28;8:260. doi: 10.3389/fmicb.2017.00260. eCollection 2017.

H5N6 is a highly pathogenic avian influenza (HPAI) and a zoonotic disease that causes recurring endemics in East Asia. At least 155 H5N6 outbreaks, including 15 human infections, have been reported in China. These repeated outbreaks have increased concern...

Non-Uniform Sample Assignment in Training Set Improving Recognition of Hand Gestures Dominated with Similar Muscle Activities.

PMID: 29483866
Front Neurorobot. 2018 Feb 12;12:3. doi: 10.3389/fnbot.2018.00003. eCollection 2018.

So far, little is known how the sample assignment of surface electromyogram (sEMG) features in training set influences the recognition efficiency of hand gesture, and the aim of this study is to explore the impact of different sample arrangements...
