This article presents a radio interface recently standardized by ETSI under the name of S-band Mobile Interactive Multimedia (S-MIM) and especially designed to provide ubiquitous messaging services over S-band GEO satellites using low-power terminals. Thanks to low terminal cost and high bandwidth efficiency, this standard allows the development of new satellite services, particularly for vehicular...
This paper presents a radio interface recently standardised by ETSI under the name of S-MIM (S-band Mobile Interactive Multimedia) and especially designed to provide messaging services over GEO satellites using low-power terminals.
This paper makes a survey of current trends and perspectives in the development of mobile satellite services in S-band in Europe. We present the recent evolutions and current status of different ongoing projects. We also identify current technology challenges and key drivers in the future evolution.
Accumulation of ornithine decarboxylase (ODC) mRNA was investigated in human monocytes and mouse peritoneal macrophages. Treatment of both populations of mononuclear phagocytes with bacterial lipopolysaccharide induced a marked and rapid increase in the accumulation of the ODC gene transcript. A similar phenomenon, albeit less pronounced, was also observed following treatment of human monocytes with...
