Millimeter-Wave Cellular Wireless Networks: Potentials and Challenges [PDF]
Proceedings of the IEEE, 2014 Millimeter-wave (mmW) frequencies between 30 and 300 GHz are a new frontier for cellular communication that offers the promise of orders of magnitude greater bandwidths combined with further gains via beamforming and spatial multiplexing from ...

Analysis of the Effect of Hull Vane Lifting Force on Fast Vessel Resistance: Straight Hull Vane
Wave, 2023 In previous studies by Saputra, the use of straight Hull Vane® increased ship's resistance. Based on hypothesis, this was caused by lifting force from Hull Vane® being too large, so that ship experienced bow trim.

Continuous-wave submillimeter-wave gyrotrons [PDF]
SPIE Proceedings, 2006 Recently, dynamic nuclear polarization enhanced nuclear magnetic resonance (DNP/NMR) has emerged as a powerful technique to obtain significant enhancements in spin spectra from biological samples. For DNP in modern NMR systems, a high power continuous-wave source in the submillimeter wavelength range is necessary. Gyrotrons can deliver tens of watts of

On coherence lengths of wave packets [PDF]
, 2009 Coherence lengths of one particle states described by quantum wave functions are studied. We show that one particle states in various situations are not described by simple plane waves but are described by wave packets that are superpositions of plane ...

Philosophical Transactions of the Royal Society B: Biological Sciences, 2004 Waves through living systems are best characterized by their speeds at 20°C. These speeds vary from those of calcium action potentials to those of ultraslow ones which move at 1–10 and/or 10–20 nm s−1. All such waves are known or inferred to be calcium waves.

Wave-Turbulence Theory of four-wave nonlinear interactions [PDF]
, 2017 The Sagdeev-Zaslavski (SZ) equation for wave turbulence is analytically derived, both in terms of generating function and of multi-point pdf, for weakly interacting waves with initial random phases.

Lower Critical Field Hc1(T) and Pairing Symmetry Based on Eilenberger Theory
, 2010 We quantitatively estimate different T-dependences of Hc1 between s wave and d wave pairings by Eilenberger theory. The T-dependences of Hc1(T) show quantitative deviation from those in London theory. We also study differences of Hc1(T) between p+ and p-
