Current research on social networking largely covers US providers. To investigate broader trends, we examine cross-cultural differences in the usage patterns of social networking services with observation and ethnographic interviews in multiple cultures. This appears to be the first systematic investigation of social networking behavior across multiple(More)
It has been shown that the atypical antipsychotic drug clozapine increases the levels of the neurosteroid allopregnanolone in the rat brain. The 18 kDa translocator protein (TSPO), formerly known as the peripheral-type benzodiazepine receptor, has been demonstrated to be involved in the process of steroid biosynthesis, in peripheral steroidogenic tissues as(More)
This report presents a simple and convenient method to generate nanoscale fractures (cracks) in smooth, single-crystalline Si substrates. The cracks propagated as approximately straight lines along the {100} crystal planes with controllable length defined by a stabilizing backlayer. Close to its tip, the crack presented a vertical offset of the two planes(More)
Composite nanostructures (approximately 200 nm wide and several micrometers long) of metal and polyaniline (PANI) in two new variations of core-shell (PANI-Au) and segmented (Au-PANI and Ni-Au-PANI) architectures were fabricated electrochemically within anodized aluminum oxide (AAO) membranes. Control over the structure of these composites (including the(More)
This study investigated cues that permit prediction of turns during passive movement through a virtual environment. Effects on simulator sickness (SS), presence and enjoyment were examined. Subjects were exposed to complex visual motion through a cartoon-like simulated environment in a driving simulator. Forward velocity remained constant and the motion(More)
This study developed a new procedure, a Virtual Guiding Avatar (VGA), which combined self-motion prediction cues and an independent visual background (IVB) to alleviate simulator sickness (SS). The VGA, which was embodied as an abstract airplane, was designed to lead the participant along a horizontal motion trajectory through a virtual environment. Both(More)
The SiO2 gate of an ion-sensitive field-effect transistor, (ISFET), is functionalized with a TiO2 film that includes imprinted molecular sites for 4-chlorophenoxy acetic acid, (1), or 2,4-dichlorophenoxy acetic acid, (2). The functionalized devices that include the imprinted interfaces reveal an impressive selectivity in the sensing of the imprinted(More)
Prolactin (PRL) affects the development and function of the reproductive system by binding to two types of receptors, which differ by the size of their intracellular domain in rodents. Whereas the signaling pathway through the long form of the receptor (PRL-RL) is well characterized, signaling through the short form (PRL-RS) remains obscure. In this(More)
