BACKGROUND Epithelial migration restores barrier function after superficial injury to any mucosa. The present study aimed to determine whether butyrate, important to colonic epithelial physiology in diverse ways, influences restoration of barrier function in the injured rat colon. METHODS Rat distal colon was transiently exposed in vitro to heat (55 degrees C for 10 sec) or to detergent (deox...

Stochastic noises have a great adverse effect on the prediction accuracy of electric power load. Modeling online and filtering real-time can effectively improve measurement accuracy. Firstly, pretreating and inspecting statistically the electric power load data is essential to characterize the stochastic noise of electric power load. Then, set order for the time series model by Akaike informati...

− The paper presents a stochastic sampling method applied to a measurement of the mean value of the product of two arbitrary signals. This method is especially convenient for measuring electric power, electric energy consumption, as well as root-mean-square of voltage and/or current. The method features a very simple hardware and the possibility of selecting the measurement accuracy by choosing...

A stretchable cm electromagnetic interference (EMI) measurement sheet is developed to enable the measurement of EMI distribution on the surface of electronic devices by wrapping the devices in the sheet. The sheet consists of an 8 8 coil array, a 2 V organic CMOS row decoder and a column selector, 40% stretchable interconnects with carbon nanotubes, and 0.18 m silicon CMOS circuits for electric...

In this review, the concept, design, performance, and a functional demonstration of multifunctional complementary metal-oxide-semiconductor (CMOS) image sensors dedicated to on-chip biosensing applications are described. We developed a sensor architecture that allows flexible configuration of a sensing pixel array consisting of optical and electric sensing pixels, and designed multifunctional C...

<p>Body impedance analysis (BIA) is used to evaluate the human body composition by measuring resistance and reactance of tissues with a high-frequency, low-intensity electric current. Nonetheless, estimation influenced many factors: status, environmental conditions, instrumentation, measurement procedure. This work studies effect connection cables, conductive electrodes, adhesive gel, BIA...

−This paper proposes a method that can be used for the resistance estimation of a PWM (Pulse Width Modulation)-driven solenoid. By using estimated solenoid resistance, the PWM duty ratio was compensated to be proportional to the solenoid current. The proposed method was developed for use with EHB (Electro-Hydraulic Braking) systems, which are essential features of the regenerative braking syste...

In this study, we propose a new concept for touch sensors based on the measurement of current generated by electrostatic induction. The proposed sensor can detect the timing of contact between two objects under perfect noncontact condition. When a human body comes in contact with an object, electrostatic charge is generated in the human body due to the tribological interaction. We assume that t...
