Bone remodeling, the function affected in osteoporosis, the most common of bone diseases, comprises two phases: bone formation by matrix-producing osteoblasts and bone resorption by osteoclasts. The demonstration that the anorexigenic hormone leptin inhibits bone formation through a hypothalamic relay suggests that other molecules that affect energy(More)
Neuropeptide B/W receptor 1 (NPBWR1) is a G-protein coupled receptor, which was initially reported as an orphan receptor, and whose ligands were identified by this and other groups in 2002 and 2003. To examine the physiological roles of NPBWR1, we examined phenotype of Npbwr1⁻/⁻ mice. When presented with an intruder mouse, Npbwr1⁻/⁻ mice showed impulsive(More)
We propose a new top-down eLearning tool for hardware logic design course using the cellular method, where students can keep focusing on their primary interests to achieve complex logic circuits design successfully. At a modern logic design classroom, hardware description languages such as VerilogHDL are mostly used to describe circuits for FPGAs (Field(More)
This paper introduces internal noise reduction combining microphones and a piezoelectric device attached to the internal noise source under blind condition. An acoustical array combining microphones and piezoelectric devices is an acoustical sensor fusion to reduce the internal noise coming from the inside of the system such as machines, vehicles or robots.(More)
Impedance scaling technique is known as a method to reduce chip area of large capacitances for low frequency integrated filters. The conventional technique realizes only grounded low impedance components. This paper proposes a construction of a floating-type impedance scaling circuit. The proposed circuit can be applied to various low frequency analog(More)
A time-frequency epsilon-filter (TF epsilon-filter) is an advanced epsilon-filter applied to complex spectra along the time axis. It can reduce most kinds of noise while preserving a signal that varies frequently such as a speech signal. The filter design is simple and it can effectively reduce noise. It is applicable not only to small amplitude stationary(More)
