In the transient process of grid-connected converter (GCC), existing research mainly focuses on impact control loops. Little attention is paid to stability issues driven by imbalance between input power and output GCC. This paper shows that will still exist even if ignoring dynamics phase-locked loop (PLL) current loop. this paper, models AC grid GCC are built under assumption PLL ignored. Then...

Various international and national regulations hold polluters liable for the cleanup of released hazardous substances and the restoration/rehabilitation of natural resources to preincident baseline conditions, a process often referred to as natural resource damage assessment and restoration (NRDAR). Here, we, the authors, describe how global climate change (GCC) will challenge each of the steps...

Colorectal cancer remains one of the major cancer- related deaths despite progress in the treatment during past decades. Detection of disease at earlier stages reduces its mortality. The aim of current study was to investigate expression of Cytokeratin 19 (CK19), Cytokeratin 20 (CK20) and Guanylyl Cyclase C (GCC) mRNA in peripheral blood of non- metastatic colorectal cancer patients which may r...

The Taihang Mountain range of north-central China, the Southern region area of Fujian province, and the Chaoshan plain of Guangdong province are 3 major regions in China well known for their high incidence of esophageal cancer (EC). These areas also exhibit high incidences of gastric cardia cancer (GCC). The ancestors of the Chaoshanese, now the major inhabitants in the Chaoshan plain, were fro...

Cancer mucosa antigens are emerging as a new category of self-antigens expressed normally in immunologically privileged mucosal compartments and universally by their derivative tumors. These antigens leverage the established immunologic partitioning of systemic and mucosal compartments, limiting tolerance opposing systemic antitumor efficacy. An unresolved issue surrounding self-antigens as imm...

Rice is the primary staple food for more than half of the world’s population but very sensitive to various abiotic stresses (submergence) causing crop loss. During abiotic stresses various genes are differentially expressed to cope up with the stress conditions. The identification of Sub1A gene was a major breakthrough for the submergence tolerance which often regulates other genes by binding t...

AIM To evaluate the clinical and prognostic significance of preoperative and postoperative cytokeratin 19 (CK19) and carcinoembryonic antigen (CEA) mRNA levels in peripheral blood of patients with gastric cardia cancer (GCC). METHODS We detected the preoperative and postoperative mRNA levels of CK19 and CEA in peripheral blood of 129 GCC patients by using reverse transcription-polymerase chai...

Embryonic development is strictly controlled by functionality of genes in which the existing networks can act both on transcription and translation regulation. Germ cell cancers (GCC) are unique because of a number of characteristics. In spite of their clinical presentation, i.e., predominantly after puberty, they arise from primordial germ cells/gonocytes that have failed appropriate maturatio...

AIM Genetic polymorphisms of drug-metabolizing enzymes have recently been shown to affect susceptibility to chemical carcinogenesis. Cytochrome P450 2E1 (CYP2E1) enzyme catalyzes the metabolism of many procarcinogens, such as N-nitrosamines and related compounds. The gene coding for this enzyme is polymorphic and thus may play a role in gastric cardia cancer (GCC) etiology. In this hospital-bas...

Recently, there has been an increased interest in the use of the time-delay estimation (TDE) technique to locate and track acoustic sources in a reverberant environment. Typically, the delay estimate is obtained through identifying the extremumof the generalized cross-correlation (GCC) function or the average magnitude difference function (AMDF). These estimators are well studied and their stat...
