Cost-sensitive boosting algorithms have proven successful for solving the difficult class imbalance problems. However, the influence of misclassification costs and imbalance level on the algorithm performance is still not clear. The present paper aims to conduct an empirical comparison of six representative cost-sensitive boosting algorithms, including AdaCost, CSB1, CSB2, AdaC1...

Background During August 2011–February 2012, an outbreak of type Π circulating vaccine-derived poliovirus (cVDPVs) occurred in Sichuan Province, China. Methods A field investigation of the outbreak was conducted to characterize outbreak isolates and to guide emergency response. Sequence analysis of poliovirus capsid protein VP1 was performed to determine the viral propagation...

Pathogenic mitochondrial DNA (mtDNA) mutations leading to mitochondrial dysfunction can cause a variety of chronic diseases in central nervous system (CNS). However, the role of mtDNA mutations in sporadic Creutzfeldt–Jakob disease (sCJD) has still been unknown. In this study, we comparatively analyzed complete mtDNA sequences of 31 Chinese sCJD patients and 32 controls. Using...
Critical dimensions for nanowire core-multishell heterostructures are analyzed by using finite-element method based on the energy equilibrium criteria. Results show that the nanowire core-shell heterostructure can sufficiently reduce the strain in the shell and increase the critical shell thickness. The critical dimensions for the nanowire core-multishell heterostructure are...
AIM: To investigate the clinical efficacy and safety of phototherapeutic keratectomy(PTK)in the treatment of bullous keratopathy(BK).METHODS: A retrospective analysis of 60 cases(60 eyes)of BK patients from Department of Ophthalmology in our hospital October 2011 to July 2014 was undergone. Clinical data of all patients with treatment of PTK were analyzed. Best corrected visual...

In this article, we study the ground states and the first radial excited states of the tensor–tensor type scalar hidden-charm tetraquark states with the QCD sum rules. We separate the ground state contributions from the first radial excited state contributions unambiguously, and obtain the QCD sum rules for the ground states and the first radial excited states, respectively. Then...

Wild rice (Zizania latifolia Griseb.) is a famous, perennial, emergent vegetable in China. The current work explores the anatomy and histochemistry of roots, stems, and leaves and the permeability of apoplastic barriers of wild rice. The adventitious roots in wild rice have suberized and lignified endodermis and adjacent, thick-walled cortical layers and suberized and lignified...

The identification of stem cells within a mixed population of cells is a major hurdle for stem cell biology–in particular, in the identification of induced pluripotent stem (iPS) cells during the reprogramming process. Based on the selective expression of stem cell surface markers, a method to specifically infect stem cells through antibody-conjugated lentiviral particles has...
AIM:To observe the effect of intravitreal injection of Ranibizumab at perioperative period of compound trabeculectomy on iris neovascularization, intraocular pressure(IOP)for patients with neovascular glaucoma(NVG).METHODS:Intravitreal injection of ranibizumab, compound trabeculectomy and panretinal photocoagulation were given to 38 patients(38 eyes)with neovascular glaucoma...

Human leukocyte antigen (HLA)-G is an immune checkpoint molecule, which expression in cervical cancer cells enables them to escape immunosurveillance. To date, limited information has been published on the association of HLA-G genetic background in malignant cells with levels of HLA-G expression and the clinical outcome of patients. We investigated the influence of the HLA-G 14...
Data are limited on the association of metabolic dysfunction-associated fatty liver disease (MAFLD) with systemic atherosclerosis. This study aimed to examine the relationship between MAFLD and the extent of atherosclerotic plaques and stenosis, and presence of polyvascular disease (PolyVD). In this cross-sectional study, MAFLD was diagnosed based on the presence of metabolic...
