Despite the large number of reports describing sponge-microbe associations, limited knowledge is available about associated fungi and their relationships with the hosts. In this work, specific fungal strains were obtained directly from in vitro sponge cell cultures (primmorphs) and single sponge cells (cytospins) and compared with those obtained from whole tissue preparations. A total of 27 fun...

Spin-transfer torque (STT) switching demonstrated in submicron sized magnetic tunnel junctions (MTJs) has stimulated considerable interest for developments of STT switched magnetic random access memory (STT-MRAM). Remarkable progress in STT switching with MgO MTJs and increasing interest in STTMRAM in semiconductor industry have been witnessed in recent years. This paper will present a review o...

* This research was supported by Basic Science Research Program through the National Research Foundation of Korea(NRF) funded by the Ministry of Education, Science and Technology(2010-0021897). Abstract As the power dissipation has become one of the critical design challenges in a sensor network environment, nonvolatile memories such as STT-MRAM and flash memory will be used in the next generat...

Polymeric 3-alkylpyridinium salts (poly-APS) present in the marine sponge Reniera sarai show a broad spectrum of biological activities. They are lytic to erythrocytes and various other mammalian cells, enabling the transfection of the latter with alien DNA. Furthermore, they show inhibitory effects to marine bacteria and can inhibit fouling of micro- and macroorganisms to submerged surfaces. Fi...

We suggested a method for localization of ischemic lesions from difference integral body surface potential maps (IBSPMs) computed by subtraction of IBSPM without manifestation of ischemia from the IBSPM during ischemia that can be obtained at rest and during the stress test. In this work the possible changes in IBSPMs of healthy subjects with increasing HR were studied. BSPMs were measured duri...
