PURPOSE To investigate the potential of noise-based tube current reduction method with iterative reconstruction to reduce radiation exposure while achieving consistent image quality in coronary CT angiography (CCTA). MATERIALS AND METHODS 294 patients underwent CCTA on a 64-detector row CT equipped with iterative reconstruction. 102 patients with fixed(More)
Minimal test cost attribute reduction is an important issue in cost-sensitive learning. Recently, an information gain based heuristic algorithm has been designed to this problem. However, the algorithm does not often find the optimal solution. In this paper, we develop an ant colony optimization algorithm to deal with this problem. First, the attribute set(More)
Test cost is often required to obtain feature values of an object. When this issue is involved, people are often interested in schemes minimizing it. In many data mining applications, due to economic, technological and legal reasons , it is neither possible nor necessary to obtain a classifier with 100% accuracy. There may be an industrial standard to(More)
BACKGROUND Medical film digitizers play an important transitory role as digital-analogue bridges in radiology. Digitized mammograms require evaluation of performance to assure medical image quality. PURPOSE To compare the diagnostic accuracy in the interpretation of breast masses using original screen-film mammograms versus digitized images. MATERIAL(More)
In many machine learning applications, we need to pay test cost for each data item. Due to limited money and/or time, we also have a constraint on the total test cost. This issue have been recently formalized as the optimal sub-reduct with test cost constraint problem. An information gain based heuristic algorithm has been proposed to deal with it. In this(More)
Premature ovarian failure (POF) is a long-term adverse effect of chemotherapy treatment. However, current available treatment regimens are not optimal. Emerging evidence suggests that bone marrow-derived mesenchymal stem cells (BMSCs) could restore the structure and function of injured tissues, but the homing and restorative effects of BMSCs on chemotherapy(More)
OBJECTIVES To evaluate the clinical value of noise-based tube current reduction method with iterative reconstruction for obtaining consistent image quality with dose optimization in prospective electrocardiogram (ECG)-triggered coronary CT angiography (CCTA). MATERIALS AND METHODS We performed a prospective randomized study evaluating 338 patients(More)
Tylototriton taliangensis was listed as a Near Threatened amphibian in IUCN red list. In this study, we sequenced the complete mitochondrial (mt) genome of this species (GenBank: KP979646) and found it contains 16,265 base pairs, which encode 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), 2 ribosomal RNA genes (rRNA) and 1 control region(More)
The direct wave and clutter wave cancellation is a key procedure for noise FM-CW (frequency-modulated continuous-wave) radar. Frequency-domain Block LMS (FBLMS) adaptive filters have better performance of clutter (include the direct wave) cancellation in low computational complex. In practical system, however, the chosen of step-size and the tap length of(More)
