1T-TaS₂ as a quantum spin liquid
(National Academy of Sciences (U.S.), 2017-05)1T-TaS₂ is unique among transition metal dichalcogenides in that it is understood to be a correlation-driven insulator, where the unpaired electron in a 13-site cluster experiences enough correlation to form a Mott ... -

2-Complexes with Large 2-Girth
(Springer US, 2017-09)The 2-girth of a 2-dimensional simplicial complex X is the minimum size of a non-zero 2-cycle in H[subscript 2](X,Z/2) . We consider the maximum possible girth of a complex with n vertices and m 2-faces. If m=n[superscript ... -
2-Hydroxy-3-methoxybenzaldehyde (o-vanillin) revisited
(International Union of Crystallography (IUCr), 2012-08)The structure of ortho-vanillin, C[subscript 8]H[subscript 8]O[subscript 3], has been revisited with modern methods and at low temperature (100 K). The previous structure [Iwasaki et al. (1976). Acta Cryst. B32, 1264-1266] ... -
2-Methylhopanoids are maximally produced in akinetes of Nostoc punctiforme: geobiological implications
(John Wiley & Sons, Inc., 2009-10)2-Methylhopanes, molecular fossils of 2-methylbacteriohopanepolyol (2-MeBHP) lipids, have been proposed as biomarkers for cyanobacteria, and by extension, oxygenic photosynthesis. However, the robustness of this interpretation ... -
2-Oxo-N-aryl-1,2,3,4-tetrahydroquinoline-6-sulfonamides as activators of the tumor cell specific M2 isoform of pyruvate kinase
(Elsevier, 2011-09)Compared to normal differentiated cells, cancer cells have altered metabolic regulation to support biosynthesis and the expression of the M2 isozyme of pyruvate kinase (PKM2) plays an important role in this anabolic ... -
2-Phenoxypyridyl Dinucleating Ligands for Assembly of Diiron(II) Complexes: Efficient Reactivity with O[subscript 2] to Form (μ-Oxo)diiron(III) Units
(American Chemical Society (ACS), 2009-10)A series of 2-phenoxypyridyl and 2-phenoxyimino ligands, H[subscript 2]L[superscript R,R′] [2,2′-(5,5′-(1,2-phenylenebis(ethyne-2,1-diyl))bis(pyridine-5,2-diyl))diphenol, where R = H, Me, or t-Bu, and R′ = H or Ph] and ... -
A 2-terminal perovskite/silicon multijunction solar cell enabled by a silicon tunnel junction
(American Institute of Physics (AIP), 2015-03)With the advent of efficient high-bandgap metal-halide perovskite photovoltaics, an opportunity exists to make perovskite/silicon tandem solar cells. We fabricate a monolithic tandem by developing a silicon-based interband ... -
A 2.4 GHz Multi-Channel FBAR-based Transmitter With an Integrated Pulse-Shaping Power Amplifier
(Institute of Electrical and Electronics Engineers (IEEE), 2013-01)A 2.4 GHz TX in 65 nm CMOS defines three channels using three high-Q FBARs and supports OOK, BPSK and MSK. The oscillators have -132 [dBc over Hz] phase noise at 1 MHz offset, and are multiplexed to an efficient resonant ... -
A 2.5-GHz asymmetric multilevel outphasing power amplifier in 65-nm CMOS
(Institute of Electrical and Electronics Engineers (IEEE), 2011-01)We present a high-efficiency transmitter based on asymmetric multilevel outphasing (AMO). AMO transmitters improve their efficiency over LINC (linear amplification using nonlinear components) transmitters by switching the ... -
2.5D cartoon models
(Association for Computing Machinery (ACM), 2010-07)We present a way to bring cartoon objects and characters into the third dimension, by giving them the ability to rotate and be viewed from any angle. We show how 2D vector art drawings of a cartoon from different views can ... -
20 years of research on the Alcator C-Mod tokamak
(American Institute of Physics (AIP), 2014-11)The object of this review is to summarize the achievements of research on the Alcator C-Mod tokamak [Hutchinson et al., Phys. Plasmas 1, 1511 (1994) and Marmar, Fusion Sci. Technol. 51, 261 (2007)] and to place that research ... -
THE 2003 OUTBURST OF THE X-RAY TRANSIENT H1743–322: COMPARISONS WITH THE BLACK HOLE MICROQUASAR XTE J1550–564
(IOP Publishing, 2009-06)The bright X-ray transient H1743−322 was observed daily by the Rossi X-ray Timing Explorer during most of its eight-month outburst in 2003. We present a detailed spectral analysis and a supporting timing analysis of all ... -
The 2005 Chios Ancient Shipwreck Survey: New Methods for Underwater Archaeology
(The American School of Classical Studies at Athens, 2009-04)In 2005 a Greek and American interdisciplinary team investigated two shipwrecks off the coast of Chios dating to the 4th-century b.c. and the 2nd/1st century. The project pioneered archaeological methods of precision ... -
2011 HM[subscript 102]: Discovery of a High-Inclination L5 Neptune Trojan in the Search for a Post-Pluto New Horizons Target
(IOP Publishing, 2013-03)We present the discovery of a long-term stable L5 (trailing) Neptune Trojan in data acquired to search for candidate trans-Neptunian objects for the New Horizons spacecraft to fly by during an extended post-Pluto mission. ... -
THE 2011 JUNE 23 STELLAR OCCULTATION BY PLUTO: AIRBORNE AND GROUND OBSERVATIONS
(IOP Publishing, 2013-08)On 2011 June 23, stellar occultations by both Pluto (this work) and Charon (future analysis) were observed from numerous ground stations as well as the Stratospheric Observatory for Infrared Astronomy (SOFIA). This first ... -
