The clock signal of modern computer processors consumes a large portion of overall chip power. By modeling global clock network wires as transmission lines and manipulating their dimensions, the global clock signal can be transformed into a standing-wave oscillator that conserves energy and reduces skew. This paper explains the lossy transmission line model and explores the effects of matching ...
Introduction The X-ray standing wave (XSW) technique provides an element-specific structural probe by using x-ray reflectivity to generate a " two-beam " interference field that in turn induces a spatial dependence to the x-ray spectroscopic yields from atoms within the field. The XSW technique is primarily used for resolving the atomic-scale structure at surfaces, interfaces, and thin films wi...
Experiments on a quasi-two-dimensional Belousov–Zhabotinsky (BZ) reaction-diffusion system, periodically forced at approximately twice its natural frequency, exhibit resonant labyrinthine patterns that develop through two distinct mechanisms. In both cases, large amplitude labyrinthine patterns form that consist of interpenetrating fingers of frequency-locked regions differing in phase by π. An...
Precise reconstruction of heterotypic cell-cell interactions in vitro requires the coculture of different cell types in a highly controlled manner. In this article, we report a standing surface acoustic wave (SSAW)-based cell coculture platform. In our approach, different types of cells are patterned sequentially in the SSAW field to form an organized cell coculture. To validate our platform, w...
We study the instability of standing-wave solutions eφω(x) to the inhomogeneous nonlinear Schrödinger equation iφt = −4φ + |x|2φ− |x|b|φ|p−1φ, x ∈ R , where b > 0 and φω is a ground-state solution. The results of the instability of standing-wave solutions reveal a balance between the frequency ω of wave and the power of nonlinearity p for any fixed b > 0.
The linacs proposed for the Next Linear Collider (NLC) and Japanese Linear Collider (JLC) would contain several thousand X-Band accelerator structures that would operate at a loaded gradient of 50 MV/m. An extensive experimental and theoretical program is underway at SLAC, FNAL and KEK to develop structures that reliably operate at this gradient. The development of standing wave structures is a...
