An Inverse-Designed Nanophotonic Interface for Excitons in Atomically Thin Materials
(American Chemical Society (ACS), 2023-09-11)Efficient nanophotonic devices are essential for applications in quantum networking, optical information processing, sensing, and nonlinear optics. Extensive research efforts have focused on integrating two-dimensional ... -
Inversion-mode GaAs wave-shaped field-effect transistor on GaAs (100) substrate
(AIP Publishing, 2015)Inversion-mode GaAs wave-shaped metal-oxide-semiconductor field-effect transistors (WaveFETs) are demonstrated using atomic-layer epitaxy of La2O3 as gate dielectric on (111)A nano-facets formed on a GaAs (100) substrate. ... -
Inverting the Swelling Trends in Modular Self-Oscillating Gels Crosslinked by Redox-Active Metal Bipyridine Complexes
(Wiley, 2017)The developing field of active, stimuli-responsive materials is in need for new dynamic architectures that may offer unprecedented chemomechanical switching mechanisms. Towards this goal, syntheses of polymerizable bipyridine ... -
Inverting the Turing Test [review of The Most Human Human by Brian Christian]
(Sigma Xi, 2011)In his book The Most Human Human, Brian Christian extrapolates from his experiences at the 2009 Loebner Prize competition, a competition among chatbots (computer programs that engage in conversation with people) to see ... -
Investigating Alaskan methane and carbon dioxide fluxes using measurements from the CARVE tower
(European Geosciences Union, 2016)Northern high-latitude carbon sources and sinks, including those resulting from degrading permafrost, are thought to be sensitive to the rapidly warming climate. Because the near-surface atmosphere integrates surface fluxes ... -
Investigating ChaMPlane X‐Ray Sources in the Galactic Bulge with Magellan LDSS2 Spectra
(American Astronomical Society, 2008)We have carried out optical and X-ray spectral analyses on a sample of 136 candidate optical counterparts of X-ray sources found in five Galactic bulge fields included in our Chandra Multiwavelength Plane Survey. We use a ... -
Investigating the Emotional Responses of Individuals to Urban Green Space Using Twitter Data: A Critical Comparison of Three Different Methods of Sentiment Analysis
(Cogitatio, 2018-03-29)In urban research, Twitter data have the potential to provide additional information about urban citizens, their activities, mobility patterns and emotion. Extracting the sentiment present in tweets is increasingly recognised ... -
Investigating the Impact of Observation Errors on the Statistical Performance of Network-based Diffusion Analysis
(Springer Verlag, 2010)Experiments in captivity have provided evidence for social learning, but it remains challenging to demon- strate social learning in the wild. Recently, we developed network-based diffusion analysis (NBDA; 2009) as a new ... -
Investigating the Initial Steps in the Biosynthesis of Cyanobacterial Sunscreen Scytonemin
(American Chemical Society (ACS), 2008)The cyanobacterial natural product scytonemin (1) functions as a sunscreen, absorbing harmful UV-A radiation. Using information from a recently identified gene cluster, we propose a biosynthetic route to this pigment. We ... -
Investigating the Mechanism of Marital Mortality Reduction: The Transition to Widowhood and Quality of Health Care
(Population Association of America, 2009)While it is well known that the widowed suffer increased mortality risks, the mechanism of this survival disadvantage is still under investigation. In this article, we examine the quality of health care as a possible link ... -
Investigating the Neural Correlates of Voice versus Speech-Sound Directed Information in Pre-School Children
(Public Library of Science, 2014)Studies in sleeping newborns and infants propose that the superior temporal sulcus is involved in speech processing soon after birth. Speech processing also implicitly requires the analysis of the human voice, which conveys ... -
Investigating the Transition Region in Scanned Probe Images of the Cyclotron Orbit in Graphene
(American Scientific Publishers, 2017-09-01)A cooled scanning probe microscope (SPM) has been used to image cyclotron orbits of electrons through high-mobility graphene in a magnetic field.1-5 In a hBN-graphene-hBN device patterned into a hall bar geometry, the ... -
Investigating xylem embolism formation, refilling and water storage in tree trunks using frequency domain reflectometry
(Oxford University Press, 2013)Trunks of large trees play an important role in whole-plant water balance but technical difficulties have limited most hydraulic research to small stems, leaves, and roots. To investigate the dynamics of water-related ... -
Investigation of the interactions between Pt(II) and Pd(II) derivatives of 5,10,15,20-tetrakis (N-methyl-4-pyridyl) porphyrin and G-quadruplex DNA
(Springer Berlin Heidelberg, 2016)Abstract G-quadruplexes are non-canonical DNA structures formed by guanine-rich DNA sequences that are implicated in cancer and aging. Understanding how small molecule ligands interact with quadruplexes is essential both ... -
Investigation of the Relation between the Spectral Energy Distributions and the Emission Lines in Low‐Redshift Quasars
(IOP Publishing, 1999)We investigate the relations between the observed emission-line strengths, widths, and continuum properties of a sample of 41 low-redshift (z<1) quasars for which contemporaneous IR/soft X-ray spectral energy distributions ... -
Investment Cycles and Sovereign Debt Overhang
(The Review of Economic Studies, 2008)We characterize optimal taxation of foreign capital and optimal sovereign debt policy in a small open economy where the government cannot commit to policy, seeks to insure a risk averse domestic constituency, and is more ... -
Investment Dynamics with Natural Expectations
(Association of the International Journal of Central Banking, 2012)We study an investment model in which agents have the wrong beliefs about the dynamic properties of fundamentals. Specifically, we assume that agents underestimate the rate of mean reversion. The model exhibits the ... -
Investment Hangover and the Great Recession
(2014)We present a model of investment hangover motivated by the Great Recession. In our model, overbuilding of residential capital requires a reallocation of productive resources to nonresidential sectors, which is facilitated ...
