The X factor: Generation X leadership in early 21st century American community colleges
(2003)A gap exists in the literature between generational studies and community college leadership studies. Concurrently, there is a wave of retirements occurring in American community colleges. The retirement phase is projected ... -
X-Ray And Optical Flux Ratio Anomalies In Quadruply Lensed Quasars. II. Mapping The Dark Matter Content In Elliptical Galaxies
(2012-01)We present a microlensing analysis of 61 Chandra observations of 14 quadruply lensed quasars. X-ray flux measurements of the individual quasar images give a clean determination of the microlensing effects in the lensing ... -
X-Ray Diagnostics for the Single Shot Laboratory Gun
(IEEE, 1993-01)The projectile packages being fired out of the 90-mm single shot gun at the Center for Electromechanics at the University of Texas at Austin (CEM-UT) have evolved into designs consisting of rods capable of penetrating ... -
X-Ray Emission From An FU Orionis Star In Early Outburst: HBC 722
(2014-10)Aims. We conducted the first X-ray observations of the newly erupting FU Ori-type outburst in HBC 722 ( V2493 Cyg) with the aim to characterize its X-ray behavior and near-stellar environment during early outburst. Methods. ... -
X-ray monitoring in heterogeneous and fractured porous media : experimental measurement and numerical modeling
The complexity of fluid flow in heterogeneous and fractured media has long been a focus in the energy industry. Models have been developed in an attempt to determine the effects of rock heterogeneity, including fractures ... -
X-Ray Structure Determination Of A Dimeric Hemoglobin From Caudina arenicola
(1995-09)The X-ray structure of a dimeric, cyanomet-liganded hemoglobin D-chain (Hb-D) from Caudina arenicola has been determined by the molecular-replacement method. The search model was a concatenated model of three hemoglobin ... -
X-Ray Tomography To Measure Size Of Fragments From Penetration Of High-Velocity Tungsten Rods
(2012-03)Behind-armor debris that results from tungsten rods penetrating armor steel at 2 km/s was studied by analysis of recovered fragments. Fragment recovery was by means of particle board. Individual fragments were analyzed by ... -
X-Shooter Observations of Main-Sequence Stars in the Globular Cluster NGC 2808: First Chemical Tagging of A He-Normal and A He-Rich Dwarf
(2010-09)We present the first chemical composition study of two unevolved stars in the globular cluster NGC 2808, obtained with the X-shooter spectrograph at VLT.NGC 2808 shows three discrete, well-separated main sequences. The ... -

xBFT : Byzantine fault tolerance with high performance, low cost, and aggressive fault isolation
(2008-05)We are increasingly relying on online services to store, access, share, and disseminate critical information from anywhere and at all times. Such services include email, digital storage, photos, video, health and financial ... -
Xenolith constraints on the origin of low δ18O values in Mauna Kea basalts: The role of self-assimilation
(2018-05)Several post-shield cones surrounding Mauna Kea volcano in Hawaii are marked by the presence of ultramafic and mafic cumulate xenoliths spanning a lithologic range from dunites to gabbros. These xenoliths offer a complimentary ... -
