N-Acyl phospholipids are atypical components of cell membranes that bear three acyl chains and serve as potential biosynthetic precursors for lipid mediators such as endocannabinoids. Biochemical studies have implicated ABHD4 as a brain N-acyl phosphatidylethanolamine (NAPE) lipase, but in vivo evidence for this functional assignment is lacking. Here, we(More)
There will come someday when UAVs can fly into the airspace of manned aircraft in the near future because of the increasing number of operational UAVs together with technologies development. Since pilots of UAVs are on the ground, the equipment for sensing and avoiding obstacles in front is indispensable. In this paper, the TCAS II, a collision avoidance(More)
Serine hydrolase inhibitors, which facilitate enzyme function assignment and are used to treat a range of human disorders, often act by an irreversible mechanism that involves covalent modification of the serine hydrolase catalytic nucleophile. The portion of mammalian serine hydrolases for which selective inhibitors have been developed, however, remains(More)
BACKGROUND Airway hyperresponsiveness (AHR) to direct stimuli, such as methacholine (MCh), is observed not only in asthma but other diseases. AHR to indirect stimuli is suggested to be more specific for asthma. The purpose of this study was to determine whether asthmatic airway inflammation is more closely related to AHR to hypertonic saline (HS), an(More)
Geometrical parameter of 1 horn, 1 parabolic, 4 Cassegrain and 1 offset-Cassegrain antennas for collision avoidance radar system in UAV are designed for the first time and then, the radiation patterns of these single-feed antennas are generated by S/W and compared. The sidelobes of the parabolic and the Cassegrain antennas are smaller than the others,(More)
Description herein is a system for simple distance measurement between an aircraft and circular mark in landing runway. The system includes an altimeter and a camera installed on the aircraft, and a circular mark placed on a landing runway. The camera on the aircraft must be oriented toward in front of the aircraft, and configured to detect the shape of the(More)
We introduce the image acquisition from X-band Inverse Synthetic Aperture Radar (ISAR) system using measurement instruments for chirp generation and signal modulation in this paper. We design and develop a power amplifier and a signal demodulator, but we use an Arbitrary Waveform Generator (N8241A, Keysight) for chirp generation and a Vector Signal(More)
In this paper, we analyze the UAV datalink design with calculating link budget of long-distance (200 km) Ku-band LOS wireless link. We calculate C/N ratio of the system and compare it with the required C/N ratio, using the CCIR reports which contain calculation of free space loss for different geography and weather, respectively. It turns out that, in 4(More)
