BACKGROUND 16S rRNA methylase-producing Gram-negative bacteria are highly resistant to all clinically important aminoglycosides. We analyzed clinical strains of 16S rRNA methylase-producing Acinetobactor baumannii and Pseudomonas aeruginosa obtained from clinical isolates in medical settings in Vietnam. METHODS From 2008 to 2011, 101 clinical strains of… (More)
For a very simple family of self-similar sets with two pieces, we prove, using a technique of Solomyak, that the intersection of the pieces can be a Cantor set with any dimension in [0, 0.2] as well as a finite set of any cardinality 2 m. The main point is that the open set condition is fulfilled for all these examples.
In this paper, we study the symmetric generalized quasi-variational inclusion problems. Then, we establish some existence theorems of solution sets for these problems. Moreover, the stability of solutions for these problems are also onbtained. Finally, we apply these results to symmetric vector quasi-equilibrium problems. The results presented in this paper… (More)
This paper is one in series of papers related to secondary school teacher cognition of Task-Based Language Teaching and of the new series of textbooks of English officially passed by in Vietnam in 2006. The purpose of this paper is to make a proposal on how task and TBLT model should be put/understood/viewed to fit the literature and the context of research… (More)
In this paper, a new tracking controller that integrates a kinematic controller (KC) with a new integral sliding mode dynamic controller (NISMC) is designed for an omnidirectional mobile robot (OMR) to track a desired trajectory at a desired velocity. First, a posture tracking error vector is defined, and kinematic controller (KC) is chosen to make the… (More)
We consider self-similar sets in the plane for which a cyclic group acts transitively on the pieces. Examples like n-gon Sierpi´nski gaskets, Gosper snowflake and terdragon are well-known, but we study the whole family. For each n our family is parametrized by the points in the unit disk. Due to a connect-edness criterion, there are corresponding Mandelbrot… (More)
In this paper, we focus on the efficiency performance of the Vietnamese commercial banks in terms of their efficiency change, productivity growth, and technological change during the period 2001–2003. We use a data envelopment analysis (DEA) model for this purpose. Productivity is measured using the Malmquist total factor productivity index. The panel data… (More)
