PURPOSE A study was conducted to determine the dosimetric effects resulting from air pockets and high atomic number (Z) contrast medium within a multichannel breast brachytherapy device. MATERIAL AND METHODS A 5-6 cm diameter Contura (SenoRx) brachytherapy device was inflated using 37 cm(3) of saline. Baseline dose falloff from an HDR Iridium-192 source was measured with the Iridium source ce...

High-bandwidth memory 2 (HBM2) vertically stacks multiple dynamic random-access (DRAM) dies to achieve a small form factor and high capacity. However, it is difficult diagnose HBM2 issues owing their structural complexity 2.5D integration with heterogeneous chips. The effects of the temperature at base logic die (TL), refresh interval stacked DRAM dies, were experimentally investigated by count...

• Symbols denoting random variables are capitalized but symbols denoting their realization are not. • Bold face is used for vectors. • Blackboard bold or non-italic face are used for sets, calligraphic face for system of sets. • We use x̄ as a shorthand for the difference 1 − x for x ∈ [0, 1]. • Z is the set of all integers and Z+ = {z ∈ Z : z ≥ 0}. • 2 is the set {0, 1}. • [n] denotes the set {...

The atomic structures of a transmembrane water plus glycerol conducting channel (GlpF), and now of aquaporin Z (AqpZ) from the same species, Escherichia coli, bring the total to three atomic resolution structures in the aquaporin (AQP) family. Members of the AQP family each assemble as tetramers of four channels. Common helical axes support a wider channel in the glycerol plus water channel par...

In this work, we investigate a three-user cognitive communication network where a primary two-user multiple access channel suffers interference from a secondary point-to-point channel, sharing the same medium. While the point-to-point channel transmitter—transmitter 3—causes an interference at the primary multiple access channel receiver, we assume that the primary channel transmitters—transmit...
