BACKGROUND Inflammatory bowel disease (IBD) can arise from genetic mutations that compromise intestinal epithelial cell integrity or immune regulation. SHIP has previously been shown to play a pivotal role in limiting the number of immunoregulatory cells and their function. AIM To determine whether SHIP plays a pivotal role in control of immune tolerance in the gut mucosa. METHODS Gastroint...

In order to reduce the conflict of yard, vehicles and quay crane in the process of loading container, and upgrade safety of the ship stowage and transport economics, this paper took minimizing reshuffle times in yard and ship, minimizing the ship center of gravity, getting appropriate trim and minimizing the total moving distance of quay crane as optimization objectives to guarantee the balance...

As a precursor to capsize, marginal stability, resulting from incorrect loading conditions and crew negligence, poses a serious danger to ships. Therefore, as a benchmark problem for preventing capsize, the use of an actively controlled pendulum for the stabilization of a marginally stable ship was analyzed. Lyapunov stability criteria and closed loop eigenvalues were used to evaluate the exten...

A new constant false alarm rate detector is proposed for ship detection in single-look and multilook intensity synthetic aperture radar images. The method is aimed at multiple target situations where the sea clutter statistics are estimated from a sample which is potentially contaminated by targets. It uses truncation to exclude outliers from the sample and truncated statistics to analyse the t...

Ship detection is an important task in sea surveillance. In the past decade, deep learning-based methods have been proposed for ship from images and videos. Convolutional features are observed to be very effective representing objects. However, scales of convolution often lead different capacities feature representation. It unclear how scale influences performance learning detection. To this en...

Hilbert-Huang Transform (HHT) and its improved method are introduced to detect and analyze power quality in ship power system for the first time, in this paper. The HHT method is used to detect surge current, voltage sag and swell, voltage interruption, etc. of the ship power system. By means of Hilbert-Huang transform, Beginning time, ending time, time-frequency, timeamplitude of the disturban...

This article proposes a novel ship detection method for high-resolution SAR images. Our goal is to look at this question from a information geometry point of view. The method consists of two steps: construction of revised metric and Riemann structure, and extraction of targets. For the first step of the process, a revised metric is introduced on Gamma 2-manifold. We construct a special Riemanni...

The 5'-phosphoinositol phosphatase SHIP negatively regulates signaling pathways triggered by antigen, cytokine and Fc receptors in both lymphocytes and myeloid cells. Mice with germ-line (null) deletion of SHIP develop a myeloproliferative-like syndrome that causes early lethality. Lymphocyte anomalies have been observed in SHIP-null mice, but it is unclear whether they are due to an intrinsic ...

This paper proposed ship classification based on covariance of discrete wavelet using probability Neural Network A set of ship profiles are used to build a covariance matrix by discrete wavelet transform using Neural Network. It is found that this method for ship classifier design offers good class discriminacy when trained with 5 ship classes. This method can discriminate noisy ship very well....
