An optical fiber pressure sensor based on the photoelastic effect using a new compensation technique is described in this paper. ’ h o optical sources and a polarization-splitting prism are incorporated into a sensor system to minimize output drifts. The four major factors-the optical source power, the fiber loss, the optical coupling loss, and the modal power distribution in fibers-are well co...

Cells were removed from three regions (anterior, mid-lateral and posterior) of Drosophila eggs at blastoderm formation, by pricking. Embryonic defects were generally correlated with the site of damage, as is also found with microcautery and with u.v. irradiation. But many structures can develop autonomously, independently of surrounding damage. Most hatching adults were normal, suggesting that ...

background : e-cadherin is a trans-membrane glycoprotein that plays a critical role in many aspects of cell adhesion as well as establishment and maintenance of epithelial cell polarity. loss of the adhesive function of e-cadherin seems to promote invasive and metastatic properties of neoplastic cells.   objectives: the present study is a retrospective study aiming to evaluate the loss of e-cad...

Soil loss erosion is one of the most serious environmental problems (widespread globally), which is a menace to sustainable ecosystems and agriculture. As the previous studies show, the world’s highest soil loss rates due to erosion are in three continents, i.e. Asia, Africa, and South America. A new method was proposed to statistically evaluate the most appropriate cell size for LS factor inpu...

The aim of this study was to analyse torsional optokinetic nystagmus (tOKN) in 17 patients with Menière's disease before and after (1 week, 1 month and 3 months) a curative unilateral vestibular neurotomy (UVN). The tOKN was investigated during optokinetic stimulations around the line of sight directed towards either the lesioned or the healthy side, at various constant angular velocities. Dyna...

This paper introduces a feedforward charge control method, which controls the displacement by the amount of current fed to the actuator. The method includes estimation and compensation of the power losses occurring in the actuator. Power losses are estimated with an experimentally created dynamic model, that does not include the load and self heating effects. Even though the method is based on ...

This paper investigates the effects of the Sarbanes-Oxley Act (SOX) on CEO compensation, using panel data constructed for the S&P 1500 firms on CEO compensation, financial returns, and reported accounting income. Empirically SOX (i) changes the relationship between a firm’s abnormal returns and CEO compensation, (ii) changes the underlying distribution of abnormal returns, and (iii) significant...

Multiplication is the main operation in many signal processing algorithms. High accuracy and low power dissipation are the most important objectives in many multimedia and lossy applications such as filtering, convolution, Euclidean distance, fast Fourier transform (FFT).The fixed width multipliers are used to maintain a fixed format and allow a little accuracy loss of output data. In this pape...

The Ini1 subunit of the SWI/SNF chromatin remodeling complex suppresses formation of malignant rhabdoid tumors in humans and mice. Transduction of Ini1 into Ini1-deficient tumor-derived cell lines has indicated that Ini1 arrests cell growth, controls chromosomal ploidy, and suppresses tumorigenesis by regulating components of the retinoblastoma (Rb) signaling pathway. Furthermore, conditional i...
