G N Ramachandran’s contributions to medical imaging
(Springer India, 2016-09)G N Ramachandran made several remarkable contributions to biophysics and structural biology over the course of his celebrated career. In a pair of seminal papers in 1971, he also laid the foundation for the technique of ... -
G-quadruplex–forming promoter sequences enable transcriptional activation in response to oxidative stress
(National Academy of Sciences (U.S.), 2017-03)Oxidative DNA damage is an implacable consequence of aerobic metabolism and often exacerbated in inflammatory processes that use reactive oxygen species (ROS) both as signaling molecules and as chemical warfare against ... -
G-stalt: A chirocentric, spatiotemporal, and telekinetic gestural interface
(Association for Computing Machinery (ACM), 2010-01)In this paper we present g-stalt, a gestural interface for interacting with video. g-stalt is built upon the g-speak spatial operating environment (SOE) from Oblong Industries. The version of g-stalt presented here is ... -
GaAsP/InGaP heterojunction bipolar transistors grown by MOCVD
(American Institute of Physics (AIP), 2017-01)Heterojunction bipolar transistors with GaAs[subscript x]P[subscript 1−x] bases and collectors and In[subscript y]Ga[subscript 1−y]P emitters were grown on GaAs substrates via metalorganic chemical vapor deposition, ... -
GABA Neurons of the VTA Drive Conditioned Place Aversion
(Elsevier, 2012-03)Salient but aversive stimuli inhibit the majority of dopamine (DA) neurons in the ventral tegmental area (VTA) and cause conditioned place aversion (CPA). The cellular mechanism underlying DA neuron inhibition has not been ... -
GABAA circuit mechanisms are associated with ether anesthesia-induced unconsciousness
(Elsevier, 2016-02)Objective: An emerging paradigm for understanding how anesthetics induce altered arousal is relating receptor targeting in specific neural circuits to electroencephalogram (EEG) activity. Enhanced gamma amino-butyric acid ... -
The Gag protein of the Drosphila telomeric retrotransposon TAHRE collaborates with HeT-A and TART Gags for nuclear localization
(Genetics Society of America, The, 2010-03)TAHRE, the least abundant of the three retrotransposons forming telomeres in Drosophila melanogaster, has high sequence similarity to the gag gene and untranslated regions of HeT-A, the most abundant telomere-specific ... -
Gain measurements of scattering-assisted terahertz quantum cascade lasers
(American Institute of Physics (AIP), 2012-06)Using terahertz time-domain spectroscopy, the gain of scattering-assisted terahertz quantum cascade lasers is measured. By examining the intersubband gain and absorption over a wide range of bias voltages, we experimentally ... -
Gain-of-Function Claims for Type-2-Diabetes-Associated Coding Variants in SLC16A11 Are Not Supported by the Experimental Data
(Elsevier BV, 2019-10)Human genetic variants inSLC16A11are associatedwith increased risk of type 2 diabetes (T2D). We pre-viously identified two distinct mechanisms throughwhich co-inherited T2D-risk coding and non-codingvariants disruptSLC16 ... -
Gain-of-function mutation of microRNA-140 in human skeletal dysplasia
(Springer Science and Business Media LLC, 2019-02-25)MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression. Heterozygous loss-of-function point mutations of miRNA genes are associated with several human congenital disorders 1–5 , but neomorphic ... -
Gain-Scheduled Higher Harmonic Control for Full Flight Envelope Vibration Reduction
(American Helicopter Society International, Inc., 2014-05)This paper investigates the dynamics of the SMART rotor, and presents a method to design a gain-scheduled controller to reduce the harmonic vibration throughout the flight envelope. The dynamics of the SMART rotor was ... -
Gaining (mutual) information about quark/gluon discrimination
(Springer-Verlag, 2014-11)Discriminating quark jets from gluon jets is an important but challenging problem in jet substructure. In this paper, we use the concept of mutual information to illuminate the physics of quark/gluon tagging. Ideal quark/gluon ... -
Gaining Acceptance by Informing the People? Public Knowledge, Attitudes, and Acceptance of Transportation Policies
(SAGE Publications, 2017-09)We examine the connection between public knowledge and attitudes in the context of urban transportation policies. We categorize policy knowledge into received, subjective, and reasoned knowledge, and measure them empirically ... -
Gait Entrainment to Torque Pulses From a Hip Exoskeleton Robot
(Institute of Electrical and Electronics Engineers (IEEE), 2022)Robot-aided locomotor rehabilitation has proven challenging. To facilitate progress, it is important to first understand the neuro-mechanical dynamics and control of unimpaired human locomotion. Our previous studies found ... -
Gait-optimized locomotion of wave-driven soft sheets
(Royal Society of Chemistry (RSC), 2020-03)Inspired by the robust locomotion of limbless animals in a range of environments, the development of soft robots capable of moving by localized swelling, bending, and other forms of differential growth has become a target ... -
GALACTIC ANGULAR MOMENTUM IN THE ILLUSTRIS SIMULATION: FEEDBACK AND THE HUBBLE SEQUENCE
(IOP Publishing, 2015-05)We study the stellar angular momentum of thousands of galaxies in the Illustris cosmological simulation, which captures gravitational and gas dynamics within galaxies, as well as feedback from stars and black holes. We ... -
The Galactic Bulge Diffuse Emission in Broadband X-Rays with NuSTAR
(American Astronomical Society, 2019-10)The diffuse hard X-ray emission that fills the Galactic center, bulge, and ridge is believed to arise from unresolved populations of X-ray binary systems. However, the identity of the dominant class of accreting objects ... -
A Galactic Origin for the Local Ionized X-ray Absorbers
(IOP Publishing, 2006-06)Recent Chandra and XMM-Newton observations of distant quasars have shown strong local (z ~ 0) X-ray absorption lines from highly ionized gas, primarily He-like oxygen. The nature of these X-ray absorbers, i.e., whether ... -
THE GALACTIC SUPERNOVA REMNANT W49B LIKELY ORIGINATES FROM A JET-DRIVEN, CORE-COLLAPSE EXPLOSION
(Institute of Physics/American Astronomical Society, 2013-02)We present results from a 220 ks observation of the Galactic supernova remnant (SNR) W49B using the Advanced CCD Imaging Spectrometer on board the Chanrda X-ray Observatory. We exploit these data to perform detailed spatially ...
