Boundary incompleteness raises great challenges to automatic prostate segmentation in ultrasound images. Shape prior can provide strong guidance in estimating the missing boundary, but traditional shape models often suffer from hand-crafted descriptors and local information loss in the fitting procedure. In this paper, we attempt to address those issues with a novel framework. The proposed fram...

We studied outlier document filtering (ODF) for extractive sentence summarization. Our results are superior compared to the average of the participant systems’ using DUC 2006. Furthermore, we add extractive paragraph summarization to the same system. It is surprising that the results are nearly the same for ROUGE metrics. Although extractive paragraph summarization has a better performance for ...

The design of an interface unit is described, in which RS232 serial data is converted to latched parallel data on 22 independent lines. The data direction of each line is programmable through the serial port. Two picocontrollers are employed in a parallel processing mode to give the required number of I/O pins, and data on the shared serial line is coded to separate data streams to the individu...

The microalgae are unicellular photosynthetic organisms that use light energy and carbon dioxide, with higher photosynthetic efficiency than plants for the production of biomass (Benemann 1997, Miao, Wu, 2006). Microalgal lipids are regarded as the feedstock of future sustainable biodiesel production owing to much higher growth rates and photosynthetic efficiencies than conventional terrestrial...

Percutaneous epididymal sperm aspiration (PESA), percutaneous testicular sperm aspiration (TESA) and testicular sperm extraction (TESE) are invasive procedures and their consequences on the testis have not been clearly defined. In order to relate the sonographic and colour Doppler flow changes to the clinical data, 14 patients with non-obstructive and six with obstructive azoospermia were exami...

BACKGROUND With increasing biobanking of biological samples, methods for large scale extraction of nucleic acids are in demand. The lack of such techniques designed for extraction from tissues results in a bottleneck in downstream genetic analyses, particularly in the field of cancer research. We have developed an automated procedure for tissue homogenization and extraction of DNA and RNA into ...

objective: dendritic cells have a critical role in control and regulation of immune responses. it is believed that these cells can be used for the treatment of many diseases. one of the methods used in immunotherapy is based on generating of tolerogenic dendritic cells through inhibition of expression costimulatory molecules. cd40 is one of the costimulatory molecules, and inhibition of express...
