We have recently discovered ethyl 4–(2–benzylhexyloxy)benzoate (KF–13) as a novel anti–juvenile hormone (anti–JH) agent (Furuta et al., 2007). This compound induced precocious metamorphosis in larvae of the silkworm, Bombyx mori, a clear sign of JH deficiency, and its activity could be completely counteracted by the simultaneous application of methoprene, a JH agonist. Although KF–13 induced ob...

BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) as a diagnostic and treatment procedure is used in most biliary tract and pancreatic. Either sedation or general anesthesia could be considered for this procedure. Combining a sedative with an opioid agent can provide effective moderate sedation. This study compared the impact of ketamine-fentanyl (KF) versus propofol-remifentanil...

Abstract: Urban canyon is categorized as hard environment for positioning of a dynamic vehicle due to low number and also bad configuration of in-view satellites. In this paper, a tuning procedure is proposed to adjust the important factors in Kalman Filter (KF) using Genetic Algorithm (GA). The authors tested the algorithm on a dynamic vehicle in an urban canyon with hard condition and compare...

An efficient method for equalization of downlink CDMA channels is presented. By describing the observed signal in terms of a state-space model, the method employs the Kalman filter (KF) to achieve an unbiased signal estimate satisfying the linear minimum mean-squared error (LMMSE) criterion. The state-space model is realized at the symbol and chip levels. With the symbollevel model, the KF is u...

This paper presents the maiden application of a variant of Kalman Filter algorithm known as Local Ensemble Transform based Kalman Filter (LET-KF) for power system harmonic estimation. The proposed algorithm is applied for estimating the harmonic parameters of a power signal containing harmonics, sub-harmonics, inter-harmonics in presence of white Gaussian noise. These algorithms are applied and...

Hepatoprotective effects of KF-14363 were investigated in the following experimental models. KF-14363 inhibited the increase in serum glutamate pyruvate transaminase (GPT) dose-dependently, and a significant inhibition was noted at a dose of 30 mg/kg or more. KF-14363 significantly inhibited the D-galactosamine (D-gal)-induced increase in serum transaminase by oral administration at 250 mg/kg x...

We derive explicit dimension formulas for irreducible MF-spherical KF-representations where KF is the maximal compact subgroup of the general linear group GLd(F) over a local field F and MF is a closed subgroup of KF such that KF/MF realizes the Grassmannian of n-dimensional F-subspaces of F. We explore the fact that (KF,MF) is a Gelfand pair whose associated zonal spherical functions identify ...

In this paper, the performance of two Kalman filter (KF) schemes based on the direct estimated model and differencing estimated model for input rate signal was thoroughly analyzed and compared for combining measurements of a sensor array to improve the accuracy of microelectromechanical system (MEMS) gyroscopes. The principles for noise reduction were presented and KF algorithms were designed t...

Purpose – The purpose of this paper is to conduct the particle swarm optimization (PSO)-assisted adaptive Kalman filter (AKF) for global positioning systems (GPS) navigation processing. Performance evaluation for the PSO-assisted Kalman filter (KF) as compared to the conventional KF is provided. Design/methodology/approach – The position-velocity also knows as constant velocity process model ca...

Thymidine kinase (TK) is a growth factor-inducible enzyme that is highly expressed in proliferating mammalian cells. Expression of mouse TK mRNA is controlled by transcriptional and posttranscriptional mechanisms including antisense transcription. Here we report the identification of a novel gene that is divergently transcribed from the bidirectional TK promoter. This gene encodes kynurenine fo...
