In this letter, we propose a novel speech emotion recognition method based on least square regression (LSR) model, in which incomplete sparse LSR (ISLSR) model is proposed and utilized to characterize the linear relationship between features corresponding labels. training ISLSR both labeled unlabeled data sets are utilized, where use of set aims enhance compatibility such that it well suitable for out-of-sample data. Another novelty lies capability dealing with feature selection. To evaluate...

To determine the factors affecting recurrence of solitary benign thyroid nodules (BTN) after microwave ablation (MWA).Between January 2013 and 2015, a total 110 patients with at least one solid nodule (solid component ≥ 80%) were enrolled. MWA was performed under continuous ultrasound (US) guidance. Before during follow-up, volume, function cosmetic complaints evaluated. Recurrence is defined by new blood flow in area or/and > 50% increase volume.Almost all significantly decreased size MWA....

Metal pollution can cause a decline in female fertility, however, previous studies have focused more on the effect of single metal fertility. In this study, we evaluated mixtures fertility based nested case-control samples. The plasma levels 22 elements from 180 women were determined by an inductively coupled mass spectrometer (ICP-MS). Minimum absolute contraction and selection operator (LASSO) penalty regression selected metals with greatest influence clinical outcome. Logistic was used to...

Serum vitamin D levels were linked to lipid metabolism in observational studies, but the exact mechanism was unclear. Several studies have attempted decipher relationship between 25(OH)D and levels. Conventional are vulnerable confounding. Mendelian randomization (MR) analysis can better control for confounding factors reverse causality, allowing inference of causal association. We, therefore, sought use MR investigate possible blood (HDL cholesterol, LDL triglycerides, total cholesterol). A...

Population-based studies have demonstrated that subclinical hypothyroidism (SCH) is an independent risk factor for atherosclerosis (OR = 1.9). However, this connection cannot be entirely explained by dyslipidemia accompanied SCH. Lipid peroxidation also plays important role in the development of atherosclerosis. In study, we aimed to evaluate oxidative stress SCH patients, as measured according concentrations hydroxy-octadecadienoic acids (HODEs) and hydroxy-eicosatetraenoic (HETEs) both...
