Sequential Covariance Intersection Fusion Robust Time-Varying Kalman Filters with Uncertainties of Noise Variances for Advanced Manufacturing.

This paper addresses the robust Kalman filtering problem for multisensor time-varying systems with uncertainties of noise variances. Using the minimax robust estimation principle, based on the worst-case conservative system with the conservative upper bounds of noise variances, the robust local time-varying Kalman filters are presented. Further, the batch covariance intersection (BCI) fusion and a fast sequential covariance intersection (SCI) fusion robust time-varying Kalman filters are presented.

MawuAP1 promotes flowering and fruit development in the basal angiosperm Magnolia wufengensis (Magnoliaceae).

The APETALA1/SQUAMOSA (AP1/SQUA)-like genes of flowering plants play crucial roles in the development processes of floral meristems, sepals, petals and fruits. Although many of the AP1/SQUA-like genes have been characterized in angiosperms, few have been identified in basal angiosperm taxa. Therefore, the functional evolution of the AP1/SQUA subfamily is still unclear.

The Relationship between Single Nucleotide Polymorphisms in Taste Receptor Genes, Taste Function and Dietary Intake in Preschool-Aged Children and Adults in the Guelph Family Health Study.

Taste is a fundamental determinant of food selection, and inter-individual variations in taste perception may be important risk factors for poor eating habits and obesity. Characterizing differences in taste perception and their influences on dietary intake may lead to an improved understanding of obesity risk and a potential to develop personalized nutrition recommendations. This study explored associations between 93 single nucleotide polymorphisms (SNPs) in sweet, fat, bitter, salt, sour, and umami taste receptors and psychophysical measures of taste.

A Study on the Susceptibility to SCC of 7050 Aluminum Alloy by DCB Specimens.

The stress corrosion cracking (SCC) of different aging states for 7050 aluminum alloy in 3.5% sodium chloride aqueous solution has been studied by means of double cantilever beam (DCB) specimens, cathodic polarization, scanning electron microscope (SEM), transmission electron microscope (TEM) and time-of-flying second ion mass spectrometer (ToF-SIMS). The results showed that the susceptibility to SCC (Iscc) of 7050 aluminum alloy decreases with increasing the aging time.

PBK/TOPK expression correlates with mutant p53 and affects patients' prognosis and cell proliferation and viability in lung adenocarcinoma.

The PDZ-binding kinase/T-LAK cell-originated protein kinase (PBK/TOPK) is highly expressed in many types of tumors. However, its role in lung adenocarcinoma remains elusive. The aims of this study were to investigate the correlation between PBK/TOPK and mutant p53 in lung adenocarcinoma and to evaluate the effect of PBK/TOPK on cell proliferation and viability.

TGF-β1 protein expression in non-small cell lung cancers is correlated with prognosis.

To investigate the expression intensity and prognostic significance of TGF-β1 protein in non-small cell lung cancer (NSCLC), immunohistochemistry was carried out in 194 cases of NSCLC and 24 cases of normal lung tissues by SP methods. The PU (positive unit) value was used to assess the TGF-β1 protein expression in systematically selected fields under the microscope with Leica Q500MC image analysis. We found that the TGF-β1 PU value was nearly two-fold higher in NSCLC than in normal lung tissues (p=0.

Estimation of the iron loss in deep-sea permanent magnet motors considering seawater compressive stress.

Deep-sea permanent magnet motor equipped with fluid compensated pressure-tolerant system is compressed by the high pressure fluid both outside and inside.

Its effect on the magnetic properties of stator core is important for deep-sea motor designers but seldom reported.

Confocal acoustic radiation force optical coherence elastography using a ring ultrasonic transducer.

We designed and developed a confocal acoustic radiation force optical coherence elastography system. A ring ultrasound transducer was used to achieve reflection mode excitation and generate an oscillating acoustic radiation force in order to generate displacements within the tissue, which were detected using the phase-resolved optical coherence elastography method. Both phantom and human tissue tests indicate that this system is able to sense the stiffness difference of samples and quantitatively map the elastic property of materials.

Sorting and identification of side population cells in the human cervical cancer cell line HeLa.

Background: Several reports have revealed that cancer stem cells (CSCs) exist in many types of solid tumors.

The aim of this study is 1) to find out a feasible way to detect the tumor stem-like cells in cervical cancer, and 2) to analyze the properties of the SP cells being sorted.

Overexpression of the insulin receptor isoform A promotes endometrial carcinoma cell growth.

Epidemiological studies have demonstrated that type 2 diabetes mellitus (T2DM) and hyperinsulinemia are associated closely with endometrial carcinoma risk, although the molecular mechanism remains unclear. Insulin receptor isoformA expression is upregulated in many cancer cells and tissues, which suggests that IR-A-mediated signaling pathways may have important implications for cancer pathogenesis. We measured the expression of insulin receptor isoforms (IR-A and IR-B in the normal endometrium tissues, the endometrial carcinoma tissues and the endometrial carcinoma cell lines.

Effects of insulin, insulin-like growth factor-I and -II on proliferation and intracellular signaling in endometrial carcinoma cells with different expression levels of insulin receptor isoform A.

Background: Hyperinsulinemia, insulin-like growth factor (IGF)-I and -II (IGF-II) are associated with increased risk of endometrial carcinoma. Insulin receptor isoform A (IR-A) is more frequently expressed in endometrial carcinoma than in normal endometrial tissues. To better understand their roles in endometrial carcinoma, we investigated the effects of insulin, IGF-I, and IGF-II in endometrial carcinomas cells with different IR-A expression levels.
