Hereditary defects of tooth dentin are classified into two main groups: dentin dysplasia (DD) (types I and II) and dentinogenesis imperfecta (DGI) (types I, II, and III). Type II DGI is one of the most common tooth defects with an autosomal dominant mode of inheritance. One disease-causing gene, the dentin sialophosphoprotein (DSPP) gene, has been reported(More)
In this paper, an impedance control algorithm based on velocity for capturing two low impact docking mechanisms (LIDMs) is presented. The main idea of this algorithm is to track desired forces when the position errors of two LIDMs are random by designing the relationship between the velocity and contact forces measured by a load sensing ring to achieve low(More)
Fuzzy vault is a recently developed cryptographic method to secure critical data with the biometric information in a way that only the authorized user can access the secret data by providing the valid biometric template. However, attackers can compromise them by cross-matching if they steel multiple vaults of a legal user. If a biometric identifier is(More)
A key problem for many medical image segmentation tasks is the combination of different-level knowledge. We propose a novel scheme of embedding detected regions into a superpixel based graphical model, by which we achieve a full leverage on various image cues for ultrasound lesion segmentation. Region features are mapped into a higher-dimensional space via(More)
The centralized extended Kalman filter is a commonly used approach for target tracking in wireless sensor networks, which usually consumes heavy computing energy on the leader of the tracking cluster. In this paper, we present a target tracking approach using wireless sensor networks based on sequential implementation of the extended Kalman filter. At every(More)
B-cell chronic lymphocytic leukemia (CLL) is characterized by profound immune dysfunction and a marked resistance to apoptosis. Understanding the cellular biology of immune effector cells from CLL patients as well as leukemic target cells is essential to developing immune mediated therapeutic strategies for CLL. In this study, an immortal CLL cell line(More)
As a similarity measure, normalized cross-correlation has found application in a broad range of image processing. A dedicated hardware implementation of normalized cross-correlation is crucial for the requirements of real-time high-speed tasks such as automatic target matching, recognition and tracking. Two efficient parallel architectures for real-time(More)
Efficient data sorting is important for searching and optimization algorithms in high time demanding fields such as image and multi-media data processing. To accelerate the data sorting algorithm applied in practical normalized crosscorrelation image matching, a novel high-speed parallel sorting scheme based on field programmable gate array (FPGA) is(More)
Delay mismatch between the input and output signals of power amplifiers (PAs) may lead to an erroneous assumption of memory effects. In adaptive digital predistortion (DPD) system, the delay mismatch affects the accuracy of coefficients estimation and degrades performance of the DPD system. In this paper, we reveal the impact of fractional delay mismatch,(More)
