 Biometric identification is an emerging technology that can solve security problems in our networked society. A few years ago, a new branch of biometric technology, palmprint authentication, was proposed [1] whereby lines and points are extracted from palms for personal identification. In this paper, we consider the palmprint as a piece of texture and(More)
The pathological lesions induced by multiwalled carbon nanotubes (MWCNTs) in bronchi and alveoli of mice were studied by intratracheal instillation and inhalation. In instillation groups, the dose was 0.05 mg MWCNTs/mouse. Similar size clumps of MWCNTs were distributed in bronchi and alveoli. The clumps led to inflammation to the lining wall of bronchi and(More)
The dysregulation of the activity of the hypothalamic-pituitary-adrenocortical (HPA) axis system is one of the major neuroendocrine abnormalities in major depression (MD). Many pieces of evidence supported that corticotropin-releasing hormone (CRH) play a role in the pathophysiology of major depression. In this article, whether genetic variations in the(More)
The scorpion venom peptides with no disulfide bridge are rarely identified and poorly characterized so far. Here, we report the identification and characterization of four novel disulfide-bridge-free venom peptides (BmKa1, BmKa2, BmKb1 and BmKn2) from Buthus martensii Kasch. BmKa1 and BmKa2 are very acidic and hydrophilic, showing no any similarity to other(More)
In this paper, we propose a book dewarping model based on the assumption that the book surface is warped as a cylinder. This model extends the model proposed by Cao and makes Cao's model a special case of our model. This extension removes the constraint of Cao's model that the camera lens must be strictly parallel to the book surface, which is hard to make(More)
BmKn2 is an antimicrobial peptide (AMP) characterized from the venom of scorpion Mesobuthus martensii Karsch by our group. In this study, Kn2-7 was derived from BmKn2 to improve the antibacterial activity and decrease hemolytic activity. Kn2-7 showed increased inhibitory activity against both gram-positive bacteria and gram-negative bacteria. Moreover,(More)
