Abstract: This paper presents a single-channel monopulse tracking method based on the time-modulated array (TMA). In this single radio frequency (RF) channel architecture, the beam steering and ...

Plasmonic nanogap confinement extends sum frequency vibrational spectroscopy to the nanoscale, enabling direct imaging of molecular orientation at interfaces. (Nanowerk News) Sum-frequency generation ...

Free software on your phone or tablet lets you scan, create, edit, annotate and even sign digitized documents on the go. By J. D. Biersdorfer I write the monthly Tech Tip column, which is devoted to ...

When a compaction runs in DataFusion with a sum aggregation on an Int32 field, it comes out in the output file as an Int64 field. In Java this means an integer is changed to a long. This can be ...

The curse placed on all Jets quarterbacks needed only two practices to claim Justin Fields as its next victim. Fields was carted off the field with a toe injury on his right foot after he dropped to ...

Abstract: With the advancement of monopulse radar technology, synthesis of the sum-and-difference patterns (SDPs) for the radome-enclosed arrays has emerged as a pressing area of research. Due to the ...

This essay in the print edition of Reason argues that courts should overturn the "open fields" doctrine of the Fourth Amendment: In a decision issued at the dawn of Prohibition, the Supreme Court ...
