This study investigates the market reaction to dividend change announcements at the Istanbul Stock Exchange. A sample of 184 announcements made by 46 companies during the period 2005 to 2008 is analyzed by using the event study methodology. The results suggest that the market reacts positively to dividend increases, negatively to dividend decreases and does not react when dividends are not chan...

Recall from last lecture that we have several ways to model leakage. One model is “only computation leaks” by Micali and Reyzin [11], which assumes a form of secure memory that does not leak as long as no computation is done on the data. Another one is “memory leakage” by Akavia, Goldwasser, and Vaikuntanathan [1], which assumes that everything can leak information. From an orthogonal dimension...

As we enter the nanoscale regime, power reduction is of increasing importance, but the established leakage reduction techniques will become less effective. Subthreshold leakage is being joined by band-to-band tunneling and gate leakage as the primary leakage mechanisms. The increased significance of these leakage components threatens the usefulness of some traditional leakage reduction techniqu...

The DRAM cells consist of one or several MOSFET devices and the subthreshold leakage current through the MOSFET strongly depends on the temperature variation. Therefore, it is obvious that the leakage of a memory cell is highly related to temperature variation. The temperature of the circuit can be measured indirectly by using leakage sensors which can be applied to various VLSI circuits becaus...

introduction: favorable apical seal of root filling materials is a crucial factor for a successful root canal treatment. the aim of this in vitro study was to compare bacterial and dye microleakage of two root canal filling materials including standard gutta-percha and nanosilver coated gutta-percha, and to evaluate the agreement between results of these two methods . materials & methods: fifty...
