The 3D structure of a periplasm-spanning platform required for assembly of group 1 capsular polysaccharides in Escherichia coli

, 2007
Capsular polysaccharides (CPSs) are essential virulence determinants of many pathogenic bacteria. Escherichia coli group 1 CPSs provide paradigms for widespread surface polysaccharide assembly systems in Gram-negative bacteria.

Impact of over-expression of colanic acid related genes identified in the screen on the histone resistance.

, 2013
We determined the minimal bactericidal concentration of histones to kill 90% (MBC90, left panels) or 99% (MBC99, right panels) of the initial bacterial inoculum after 1 h of incubation.

Vector Superposition Quadratic Gaussian Wyner-Ziv Coding

, 2010
本論文主要探討的問題在於，在二次高斯(Quadratic Gaussian)的假設下，如何為Wyner-Ziv編碼理論設計出一套實際的編碼方式。首先，本論文會介紹及討論Wyner-Ziv編碼理論。之後我們會分析在二次高斯的假設下Wyner-Ziv編碼的架構。這個假設之所以會引起廣泛的討論，是因為在此假設下的資料率失真(Rate-distortion)邊界，會等於在編碼器跟解碼器雙方都有附加資訊(Side information)的情況下的資料率失真邊界。在二次高斯Wyner-Ziv編碼的情況下 ...

Genetic, virulence, and antimicrobial resistance characteristics associated with distinct morphotypes in ST11 carbapenem-resistant Klebsiella pneumoniae

Virulence
ST11 is the most common lineage among carbapenem-resistant Klebsiella pneumoniae (CRKP) infections in Asia. Diverse morphotypes resulting from genetic mutations are associated with significant differences in microbial characteristics among K.
