Nam H Lee, Runze Tang, Carey E Priebe, Michael Rosen
We consider a problem of clustering a sequence of multinomial observations by way of a model selection criterion. We propose a form of a penalty term for the model selection procedure. Our approach subsumes both the conventional AIC and BIC criteria but also extends the conventional criteria in a way that it can be applicable also to a sequence of sparse multinomial observations, where even within a same cluster, the number of multinomial trials may be different for different observations. In addition, as a preliminary estimation step to maximum likelihood estimation, and more generally, to maximum Lq estimation, we propose to use reduced rank projection in combination with non-negative factorization...

Here, we report the complete genome sequences of two tembusu virus strains, ZC-1 and LQ-1, isolated from ducks and geese, respectively, in 2012. Phylogenetic analysis showed that the nucleotide and amino acid sequences of the two strains are closely related to those of the TMUV isolates around Shandong province. The full-length genome sequences of two waterfowl-origin TMUVs provided herein will help to understand the molecular epidemiology of tembusu virus in China, which deserves further investigation.

AIM OF STUDY: The quality of cardiopulmonary resuscitation (CPR) is an important factor in the outcome of cardiac arrest. Our objective was to compare outcomes following either immediate low-quality (LQ) CPR or delayed high-quality (HQ) CPR. We hypothesized that delayed HQ CPR will improve the outcomes of CPR in comparison to immediately performing LQ CPR. METHODS: Eighteen Sprague-Dawley rats were randomized into two groups: (1) Delayed HQ CPR (HQ group, n = 9)...

The kinetic characteristics of Zn uptake by Potentilla griffithii Hook. f. var. velutina Card. were studied with hydroponic culture under different Zn supply and its exposure time. When the Zn supply was 10 mg x L(-1), the Zn concentration in shoot and root reached the peak on the 8th day, being 2.49 x 10(3) mg x kg(-1) and 2.21 x 10(3) mg x kg(-1), respectively; while when the supply was 100 mg x L(-1), the Zn concentration in shoot reached the maximum (1.23 x 10(3) mg x kg(-1)) on the 16th day, but that in root did not exhibit saturation...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
