With the advent of sequencing technology, numerous gene expression data are generated. Identifying differentially expressed genes play an important role in the gene therapy of cancer patients. As an useful mathematical tool, nonnegative matrix factorization (NMF) has been successfully used for identifying differentially expressed genes. In this paper, a novel method named robust graph regularized...
Robust visual object tracking against occlusions and deformations is still very challenging task. To tackle these issues, existing Convolutional Neural Networks (CNNs) based trackers either fail to handle them or can just run in low speed. In this paper, we present a realtime tracker which is robust to occlusions and deformations based on a Region-based, Multi-Scale Fully Convolutional Siamese Network...
Low-rank representation (LRR) via rank minimization is a high efficiency method for capturing low-dimensional structure embedded in high-dimensional data. However, minimizing the rank of a matrix is NP-hard. In this paper, robust truncated nuclear norm low-rank representation regularized by L2,1-norm method (RTLRR) is proposed. The truncated nuclear norm is introduced to replace the nuclear norm to...
Iterative learning control is applicable to systems that make sweeps or passes through dynamics defined over a finite duration. Once each pass is complete all information generated as its dynamics evolve are available for use in designing the control action to be applied on the next sweep. The design problem is to construct a sequence of control inputs to enforce convergence to a specified reference...
A novel hundred-microsecond histotripsy treatment method is proposed. This method utilizes the confocal dual-frequency of second harmonic superimposition control approach. A custom-designed transducer consisting of two confocal spherical-annular element arrays is used. The frequencies of the transducer are 1.1 and 2.2 MHz, and the peak negative pressures are 5 MPa and 12 MPa with shock wave. Due to...
Kidney cancer is a severe disease which can be treated by using a non-invasive, controllable and focused ultrasound surgery method-histotripsy. Previously, histotripsy produced by hundred-microsecond-long focused ultrasound pulses has been proposed by us, which generates mechanical homogenized lesion by employing boiling bubbles and high duty cycle compared with conventional methods. However, the...
The influence of ozone surface treatment on surface flashover performance of epoxy resin/AhO3 microcomposites was investigated. Epoxy resin/AhO3 microcomposite samples with a diameter of 50 mm and a thickness of 1 mm were prepared and treated by ozone for various periods. Surface potential decay, surface conductivity, secondary electron emission coefficient, and surface flashover voltage in SF6 of...
SiO2/LDPE nanocomposites can effectively decrease space charge accumulation at room temperature. However, space charge build up and suppress mechanism in nanocomposite are still not well understood. Experiments results showed that LDPE has a TSC peak around 60°C and the mechanical loss curve of LDPE which has a peak corresponding to the α-relaxation correspond well to the TSC peak. Space charge of...
We have developed an ultrabroadband thermal light emitter based on carbon nanotube fibers driven either by continuous or pulsed current. Particularly, in pulsed mode, this emitter provides shorter and more intense pulses of terahertz radiation than conventional thermal emitters.
ID3 decision tree data mining is a popular and widely studied data analysis technique for a range of applications. In this paper, we focus on the privacy-preserving ID3 decision tree algorithm on horizontally partitioned datasets. In such a scenario, data owners wish to learn the decision tree result from a collective data set but disclose minimal information about their own sensitive data. In this...
A patch antenna augmented with a magnetic surface plasmon polariton (SPP) spiral is proposed. It is fed by a small loop antenna. The final prototype of the optimized antenna has an overall size of 80 mm × 80 mm × 1 mm. Simulation results show that it has three working frequency bands; the −10 dB impedance bandwidth of each is: 1.99–2.52 GHz, 3.22–4.26 GHz and 4.71–5.16 GHz. These three working frequency...
Cloud storage service has been increasing in popularity as cloud computing plays an important role in the IT domain. Users can be relieved of the burden of storage and computation, by outsourcing the large data files to the cloud servers. However, from the cloud service providers' point of view, it is wise to utilize the data deduplication techniques to reduce the costs of running large storage system...
The emergence and development of the Internet resulted in the generation of huge amounts of data, which are often distributed among different sites. Many organizations and companies attempted to mine the data with cloud computing. However, given the rise of various privacy issues, sensitive data (e.g., medical records) need to be encrypted before outsourcing to the cloud. To process data mining, such...
Many companies want to share data for datamining tasks. However, the privacy and security concerns become a bottleneck in the data sharing filed. The secure multiparty computation (SMC)-based privacy-preserving data mining has emerged as a solution to this problem. However, traditional SMC solutions are inefficient. We introduce the method of outsourcing to reduce the computation cost of user’s side...

In [2], a distributed algorithm has recently been developed for solving linear algebraic equations via multi-agent networks. To adopt the algorithm, each agent only has to know part of the linear equation as well as its nearby neighbors' estimates to the solution. In this paper, we would like to further discuss this algorithm from the following two perspectives. The first one is to improve the numerical...
This paper presents a variable frequency-phase shift(VF-PS) control method used in series/series compensated inductive contactless power transfer (ICPT) system with unity-power-factor input. VF-PS control searches proper working point automatically, which provides a way avoiding considering the complex ICPT output characteristics caused by the changing coupling coefficient and load and ensures ZVS...
Robust Principal Component Analysis (RPCA) is an efficient method in the selection of differentially expressed genes. However, nuclear norm minimizes all singular values simultaneously, so it may not be the best solution to replace the low-rank function. In this paper, the truncated nuclear norm is introduced. And a new method named Truncated nuclear norm regularized Robust Principal Component Analysis...
Sparse Principal Component Analysis (SPCA) is a method that can get the sparse loadings of the principal components (PCs), and it may formulate PCA as a regression-type optimization problem by using the elastic net. But the selected features are different with each PC and generally independent. A new method named SPCA has been proposed for removing these detect, which replaces the elastic net with...
