OBJECTIVES/HYPOTHESIS Needle electrode-based electromechanical reshaping (EMR) is a novel, ultra-low-cost nascent surgical technology to reshape cartilage with low morbidity. EMR uses direct current to induce mechanical relaxation in cartilage that is first deformed into a required geometry, which in turn leads to permanent shape change. The objective of this study was to determine the effect o...

Development of medical micro-assay systems must be based on an understanding of blood flow mechanics at scales of tens to hundreds of microns. This study investigated the use of a simple power law model for blood flow of between 2.5 and 100 μl/min in channels with 200 x 60 μm cross-sections and the following configurations: straight, 90 degree bend, and sudden contraction from 200 to 100μm. Exp...

Two active areas of research in the field of integrated optics are the coupling of on-chip waveguides to off-chip optical fibers and the reduction of circuit size which is dominated by the minimum bend radius of waveguides. Traditional approaches using mask-based lithography involve the complex etching of micro-mechanical on-chip mounts for the fiber or total-internal-reflection facets for shar...

A photonic integrated circuit (PIC) comprised of an 11 cm long multimode speckle waveguide, a 1 × 32 splitter, and linear grating coupler array is fabricated utilized to receive 2 GHz radio-frequency (RF) signal bandwidth from 2.5 4.5 using compressive sensing (CS). Incoming RF signals are modulated onto chirped optical pulses which input the waveguide. The waveguide produces random projections...

We prove that every set S of ∆ slopes containing the horizontal slope is universal for 1-bend upward planar drawings of bitonic st-graphs with maximum vertex degree ∆, i.e., every such digraph admits a 1-bend upward planar drawing whose edge segments use only slopes in S. This result is worst-case optimal in terms of the number of slopes, and, for a suitable choice of S, it gives rise to drawin...

The state-resolved reaction probability of CH4 on Pt 110 1 2 was measured as a function of CH4 translational energy for four vibrational eigenstates comprising different amounts of C-H stretch and bend excitation. Mode-specific reactivity is observed both between states from different polyads and between isoenergetic states belonging to the same polyad of CH4. For the stretch/bend combination s...

It is proved that every series-parallel digraph whose maximum vertex-degree is ∆ admits an upward planar drawing with at most one bend per edge such that each edge segment has one of ∆ distinct slopes. This is shown to be worst-case optimal in terms of the number of slopes. Furthermore, our construction gives rise to drawings with optimal angular resolution π ∆ . A variant of the proof techniqu...
