Discovery of Seven Companions To IntermediateMass Stars With Extreme Mass Ratios in the ScorpiusCentaurus Association
(201506)We report the detection of seven lowmass companions to intermediatemass stars (SpT B/A/F; M similar to 1.54.5M(circle dot)) in the ScorpiusCentaurus (ScoCen) Association using nonredundant aperture masking interferometry. ... 
Discovery of SiCSi in IRC+10216: A Missing Link Between Gas and Dust Carriers of SiC Bonds
(201506)We report the discovery in space of a disilicon species, SiCSi, from observations between 80 and 350 GHz with the IRAM 30 m radio telescope. Owing to the close coordination between laboratory experiments and astrophysics, ... 
The Discovery Of Stellar Oscillations In The K Giant Iota Draconis
(200811)iota Dra (HIP 75458) is a wellknown example of a K giant hosting a substellar companion. We present radial velocity measurements of this star from observations taken with three different instruments spanning nearly 8 ... 
Discovery of the Transiting Planet Kepler5B
(201004)We present 44 days of high duty cycle, ultra precise photometry of the 13th magnitude star Kepler5 (KIC 8191672, T(eff) = 6300 K, log g = 4.1), which exhibits periodic transits with a depth of 0.7%. Detailed modeling of ... 
Discovery Of The UltraBright Type IIL Supernova 2008es
(200901)We report the discovery by the Robotic Optical Transient Search Experiment (ROTSEIIIb) telescope of SN 2008es, an overluminous supernova (SN) at z = 0.205 with a peak visual magnitude of 22.2. We present multiwavelength ... 
Discovery, observations and theory of over luminous supernovae and peculiar transients
(201005)Modern widefield imaging transient search projects led to the discovery of a new class of rare, overluminous stellar explosions. Events like SN 2005ap (Quimby et al. 2007a), SN 2006gy (Quimby 2006; Smith et al. 2007), ... 
Discovery, Progenitor and Early Evolution of A Stripped Envelope Supernova iPTF13bvn
(201309)The intermediate Palomar Transient Factory reports our discovery of a young supernova, iPTF13bvn, in the nearby galaxy, NGC 5806 (22.5 Mpc). Our spectral sequence in the optical and infrared suggests a Type Ib classification. ... 
Discovery of the Mexican Blindcat, Prietella phreatophila, in the U.S., and an update on its rangewide conservation status
(20170303)Mexican blindcat, Prietella phreatophila, was described in 1954 from a single locality in Northern Coahuila, México. Long listed as endangered by the Mexican federal government, it was listed by the U.S. Fish and Wildlife ... 
Discrete approximations to continuous distributions in decision analysis
(201405)In decision analysis, continuous uncertainties (i.e., the volume of oil in a reservoir) must be approximated by discrete distributions for use in decision trees, for example. Many methods of this process, called discretization, ... 
Discrete deterministic chaos
(201008)In the course Discrete Deterministic Chaos, Dr. Mark Daniels introduces students to Chaos Theory and explores many topics within the field. Students prove many of the key results that are discussed in class and work through ... 
Discrete element model of wave propagation in steelcement region
(200612)In modern drilling practice a cement sheath supports the casing strings and provides zonal isolation in the wellbore. From a well production standpoint zonal isolation is the most important aspect of the cement sheath. The ... 
Discrete element modeling of rock fracture behavior: fracture toughness and timedependent fracture growth
(2006)Understanding the mechanics of fracture is important in oil and gas reservoirs. Applications range from the characterization of natural fractures that enhance fluid flow to the prediction of fracturing around a wellbore ... 
Discrete gate sizing and threshold voltage assignment to optimize power under performance constraints
(201308)In today's world, it is becoming increasingly important to be able to design high performance integrated circuits (ICs) and have them run at as low power as possible. Gate sizing and threshold voltage (Vt) assignment ... 
Discrete Hamilton's equations for thermoelectromagnetic systems
(201005)Energy methods are used extensively in the formulation of discrete system models. They simplify the systematic integration of diverse kinematic schemes, and are well suited for characterizing complex energy domain coupling ... 
Discrete Lagrange equations for reacting thermofluid systems
(200905)The application of Lagrange's equations to nonequilibrium reacting compressible thermofluid systems yields a modeling methodology for thermofluid dynamics compatible with the discrete energy methods used extensively in ... 
Discrete negative emotions generated in an interactive advertisement: an exploration of control as a medium effect
(2002)Some researchers believe that affective experiences on interactive media are different than in traditional media or in real life. This study ‘s objective is to explain emotion elicitation in interactive media by applying ... 
A discrete velocity method for the Boltzmann equation with internal energy and stochastic variance reduction
(201512)The goal of this work is to develop an accurate and efficient flow solver based upon a discrete velocity description of the Boltzmann equation. Standard particle based methods such as Direct Simulation Monte Carlo (DSMC) ...
