A sufficient condition is found for each subproduct of a Blaschke product to have an asymptotic value of modulus 1 along a prescribed arc of a specified type in the unit disc. The condition obtained ...

In hard disk drives, digital information is stored and retrieved magnetically by a “read head” that flies over the disk within tens of nanometers of its surface. Figure 1 is a photograph of a read ...

In digital circuits, insulating dielectrics separate the conducting parts (wire interconnects and transistors) from one another. As components have scaled down and transistors have gotten closer and ...
