1.3 mm WAVELENGTH VLBI OF SAGITTARIUS A*: DETECTION OF TIME-VARIABLE EMISSION ON EVENT HORIZON SCALES
(Institute of Physics/American Astronomical Society, 2011-02)Sagittarius A*, the ~4 × 10[superscript 6] M ☉ black hole candidate at the Galactic center, can be studied on Schwarzschild radius scales with (sub)millimeter wavelength very long baseline interferometry (VLBI). We report ... -
1.8-μm thulium microlasers integrated on silicon
(SPIE, 2016-02)A key challenge for silicon photonic systems is the development of compact on-chip light sources. Thulium-doped fiber and waveguide lasers have recently generated interest for their highly efficient emission around 1.8 μm, ... -
1/2 (e[superscript 2]/h) Conductance Plateau without 1D Chiral Majorana Fermions
(American Physical Society, 2018-03)We address the question about the origin of the 1/2(e[superscript 2]/h) conductance plateau observed in a recent experiment on an integer quantum Hall (IQH) film covered by a superconducting (SC) film. Since one-dimensional ... -
1/N effects in non-relativistic gauge-gravity duality
(Institute of Physics, 2009-03)We argue that higher-curvature terms in the gravitational Lagrangian lead, via non-relativistic gauge-gravity duality, to nite renormalization of the dynamical exponent of the dual conformal eld theory. Our argument ... -
10 Gbps TCP/IP streams from the FPGA for High Energy Physics
(IOP Publishing, 2014-06)The DAQ system of the CMS experiment at CERN collects data from more than 600 custom detector Front-End Drivers (FEDs). During 2013 and 2014 the CMS DAQ system will undergo a major upgrade to address the obsolescence of ... -
10 Gbps TCP/IP streams from the FPGA for the CMS DAQ eventbuilder network
(IOP Publishing, 2013-12)For the upgrade of the DAQ of the CMS experiment in 2013/2014 an interface between the custom detector Front End Drivers (FEDs) and the new DAQ eventbuilder network has to be designed. For a loss-less data collection from ... -
A 10-Gb/s Compact Low-Power Serial I/O With DFE-IIR Equalization in 65-nm CMOS
(Institute of Electrical and Electronics Engineers, 2009-12)A compact and power-efficient serial I/O targeting dense silicon carrier interconnects is reported. Based on expected channel characteristics, the proposed I/O features low-impedance transmitter termination, high-impedance ... -
10-nm Fin-width InGaSb p-channel self-aligned FinFETs using antimonide-compatible digital etch
(Institute of Electrical and Electronics Engineers (IEEE), 2018-01)We have fabricated self-aligned InGaSb p-channel FinFETs using a novel antimonide-compatible digital etch. This is the first demonstration of digital etch on InGaSb-based transistors of any kind. It has enabled the first ... -
100 Years of Progress in Tropical Cyclone Research
(American Meteorological Society, 2018-01)A century ago, meteorologists regarded tropical cyclones as shallow vortices, extending upward only a few kilometers into the troposphere, and nothing was known about their physics save that convection was somehow involved. ... -
100 Years of the American Economic Review: The Top 20 Articles
(American Economic Association, 2011-02)This paper presents a list of the top 20 articles published in the American Economic Review during its first 100 years. This list was assembled in honor of the AER's one-hundredth anniversary by a group of distinguished ... -
100 Years of the Ocean General Circulation
(American Meteorological Society, 2018-01)The central change in understanding of the ocean circulation during the past 100 years has been its emergence as an intensely time-dependent, effectively turbulent and wave-dominated, flow. Early technologies for making ... -

100-nm tunable femtosecond Cr:LiSAF laser mode locked with a broadband saturable Bragg reflector
(Optical Society of America, 2017-04)We report broad tunability of a femtosecond (fs) diode-pumped Cr:LiSAF laser mode-locked with a broadband saturable Bragg reflector (SBR). The SBR had seven pairs of Al[subscript x]O[subscript y]I(n∼1.5) and Al[subscript ... -
100-W Q-switched Cryogenically Cooled Yb:YAG Laser
(Institute of Electrical and Electronics Engineers, 2009-12)This work describes a cryogenic, electro-optically Q-switched Yb:YAG laser that generates 114-W average TEM[subscript 00] power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration ... -
A +10dBm 2.4GHz Transmitter with sub-400pW Leakage and 43.7% System Efficiency
(Institute of Electrical and Electronics Engineers (IEEE), 2015-02)Extreme energy constraints inherent in many exciting new wireless sensing applications (such as [1-3]) virtually dictate that such systems operate with extremely low duty cycles, harvesting and storing energy over long ... -
A 10Gb/s compact low-power serial I/O with DFE-IIR equalization in 65nm CMOS
(Institute of Electrical and Electronics Engineers, 2009-05)The design of compact low-power I/O transceivers continues to be a challenge for both chip-to-chip and backplane applications. The introduction of dense fine-pitch silicon packaging technologies, that in principle are ... -
10 nm gap bowtie plasmonic apertures fabricated by modified lift-off process
(American Institute of Physics (AIP), 2016-09)Bowtie plasmonic apertures, with gap sizes down to 11 nm and silver film thickness of up to 150 nm (aspect ratio 14:1), were fabricated on a silicon nitride membrane. Transmission spectra feature the aperture resonances ... -
