Data Envelopment Analysis (DEA) as a non–parametric method is used to measure relative performance of organizational units. The aim of this paper is to develop a new model to evaluate the efficiency of a general two-stage network structures proposed by Li et al.  (2012) for measuring the performance of Decision Making Units (DMUs). In addition, this paper expands the work of Li et al. (2012) an...

Several methods have been developed for the estimation of foetal haemoglobin levels by alkali denaturation (Singer, Chernoff, and Singer, 1951; Betke, Marti, and Schlicht, 1959; Kristoffersen, 1961) but there have been increasing demands for a simple method which is sensitive enough to measure reproducibly small elevations of foetal haemoglobin in both inherited and acquired haematological diso...

Confocal neurolasermicroscopy (NLM)(Schlosser et al., 2009 (Epub)) is the current front end of the innovative process in neurosurgery for optimizing the operative results. Hence NLM is the continuance of a protracted development. Microscopic imaging technologies in neurosurgery invented 50 years ago revealed new strategies and possibilities for surgeons. These techniques were first used with ma...

In functional magnetic resonance imaging (fMRI) studies, the blood oxygen level-dependent (BOLD) signal change, in contrast to noise, is typically small (< 5%; e.g., Chen & Small, 2007). Although the quality of acquired image data may be improved by pre-processing images with lowor high-pass filters, classification of voxels into the active/inactive status could vary from one study to the next ...

In this paper, we propose an integrated Genetic Algorithm with Hill Climbing to solve the matrix bandwidth minimization problem, which is to reduce bandwidth by permuting rows and columns resulting in the nonzero elements residing in a band as close as possible to the diagonal. Many algorithms for this problem have been developed, including the wellknown CM and GPS algorithms. Recently, Marti e...

The SLX4 protein functions as a platform for catalytic subunits of structure-specific endonucleases. Findings reported in Cell (Fekairi et al., 2009; Svendsen et al., 2009) and in Molecular Cell (Andersen et al., 2009; Muñoz et al., 2009) now identify the human SLX4 and show that in association with the SLX1 endonuclease it directs the symmetric cleavage and resolution of Holliday junctions.
