Toll-like receptor 3 (TLR3) participates in the innate immune response by recognizing viral pathogens. In this study, human brain astrocytes were found to constitutively express TLR3, and this expression was increased by interferon-gamma (IFN-gamma) or double-stranded RNA (dsRNA). Treatment employing dsRNA in astrocytes induced IFN regulatory factor 3(More)
Lipo-PGE1 [EGLANDIN(®) ; a lipid microsphere-incorporated prostaglandin E1 (PGE1)] stimulates angiogenesis and promotes the healing of skin ulcers. Because the effects of Lipo-PGE1 on cutaneous wound healing are not completely understood, we investigated the ability of Lipo-PGE1 to affect in vivo wound healing and regulate the migration of human dermal(More)
This paper presents a knowledge based hybrid algorithm using Sigma-Delta STAP which is practical and powerful in non-homogeneous environments. In the hybrid algorithm, statistical and non-statistical direct data domain (D) algorithms are combined to obtain the advantages of both approaches. In this paper a new revised D algorithm which uses a maximum SINR(More)
Bi-static and multi-static radar requires synchronization between transmitter(s) and receiver(s) due to their separated locations. Especially, for the target Doppler estimation, the carrier frequency offset occurred by the discord between the transmit and the receive ends should be estimated before the processing. In this paper, the system model for(More)
INTRODUCTION The purpose was to identify fall risk factors between admission day and fall occurred day using electronic nursing records and the Morse Fall Scale (MFS). METHODS The MFS and fall related data were obtained through retrospective chart review from June 1, 2014 to May 31, 2015. Descriptive statistics and McNemar test were used for statistical(More)
In this paper, a novel algorithm estimating not only target's rotation velocity (RV) but also rotation center (RC) is proposed for inverse synthetic aperture radar (ISAR) image cross-range scaling. Scale invariant feature transform (SIFT) is applied to two different ISAR images formed at different aspect angles for extracting non-fluctuating scattering(More)
The need to deal with non-homogeneous clutter has driven much of the recent research in space-time adaptive processing (STAP). This paper presents an extension of the low-complexity, sigma-delta (ΣΔ) algorithm incorporating the direct data domain (D) processing. The new algorithm is practical and improves target detection in non-homogeneous clutter(More)
