The Coastal Jet:Observations of Surface Currents Over the Oregon Continental Shelf From HF Radar
Coastal Jet Surface Currents Oregon Continental Shelf HF Radar
font style='font-size:12px;'>
2015/8/10
The ocean circulation over the Oregon shelf during spring and summer is dominated by the effects of coastal upwelling. Equatorward winds drive an offshore Ekman transport in the surface layer, which p...
Detection, tracking and event localization of jet stream features in 4-D atmospheric data
Detection tracking event localization jet stream features 4D atmospheric data
font style='font-size:12px;'>
2014/12/11
We introduce a novel algorithm for the efficient detection and tracking of features in spatiotemporal atmospheric data, as well as for the precise localization of the occurring genesis, lysis, merging...
Jet bundles on projective space: New examples
Atiyah sequence jet bundle characteristic class generalized Atiyah class
font style='font-size:12px;'>
2012/6/21
In previous papers it was shown that the left and right O-module structure of the jet bundles on the projective line differed. In this paper we show that similar statements hold for jet bundles on pro...
A two-component jet model based on the Blandford-Znajek and Blandford-Payne processes
two-component jet model Blandford-Znajek Blandford-Payne processes
font style='font-size:12px;'>
2012/2/23
We propose a two-component jet model consistent with the observations of several gamma ray bursts (GRBs) and active galactic nuclei (AGNs). The jet consists of inner and outer components, and they are...
Frame-dragging, disk warping, jet precessing, and dipped X-ray lightcurve of Sw J1644+57
Frame-dragging disk warping jet precessing dipped X-ray lightcurve Sw J1644+57
font style='font-size:12px;'>
2012/2/23
The X-ray transient source Sw J1644+57 recently discovered by Swift is believed to be triggered by tidal disruption of a star by a rapidly spinning supermassive black hole (SMBH). For such events, the...
Research on Ink-Jet Printing Process of the Leather
Depth of the Color Leather Digital Printing Rubbing Fastness
font style='font-size:12px;'>
2011/11/22
This research studies the effect of penetrant, formic acid, sodium bicarbonate and steaming time on the rubbing fastness and K/S value of printed leather. The results show that the optimum concentrati...
Gamma-Ray and Parsec-Scale Jet Properties of a Complete Sample of Blazars From the MOJAVE Program
Gamma-Ray Parsec-Scale Jet Properties Complete Sample Blazars From MOJAVE Program
font style='font-size:12px;'>
2011/10/19
We investigate the Fermi LAT gamma-ray and 15 GHz VLBA radio properties of a joint gamma-ray- and radio-selected sample of AGNs obtained during the first 11 months of the Fermi mission (2008 Aug 4 - 2...
Detection of jet precession in the active nucleus of M81
Galaxies: Individual: M81 – galaxies: active – galaxies: jets – galaxies: nuclei – radio continuum: galaxies–radiation mechanisms: nonthermal – astrometry

2011/9/27
(See the complete and formatted abstract in the paper). We report on VLBI monitoring of the low-luminosity AGN (LLAGN) in M81 at 1.7, 2.3, 5, and 8.4GHz. These observations are phase-referenced to the...
From the Blazar Sequence to the Blazar Envelope: Revisiting the Relativistic Jet Dichotomy in Radio-loud AGN
Blazar Envelope Revisiting Relativistic Jet Dichotomy Radio-loud AGN
font style='font-size:12px;'>
2011/10/21
We revisit the concept of a blazar sequence that relates the synchrotron peak frequency ({\nu}peak) in blazars with synchrotron peak luminosity (Lpeak, in {\nu}L{\nu}) using a large sample of radio-lo...
Very Long Baseline Array Imaging of Parsec-scale Jet Structures in Radio-loud Narrow-line Seyfert 1 Galaxies
Long Baseline Array Imaging Radio-loud Narrow-line Seyfert
font style='font-size:12px;'>
2011/10/21
We conducted very long baseline interferometry (VLBI) observations of five radio-loud narrow-line Seyfert 1 (NLS1) galaxies in milliarcsecond resolutions at 1.7 GHz (18 cm) using the Very Long Baselin...

2011/7/21
We use our non-conformal holographic bottom-up model for QCD described in 1012.0116 to further study the effect of the QCD trace anomaly on the energy loss of both light and heavy quarks in a strongly...
Some new results for "jet" stopping in AdS/CFT
Some new results stopping AdS/CFT
font style='font-size:12px;'>
2011/7/21
We give a breezy, qualitative overview of some of our recent results on studying jet stopping in strongly-coupled plasmas using gauge-gravity duality. Previously, people have found that the maximum st...
Implications for the structure of the relativistic jet from multiwavelength observations of NGC 6251

2011/10/13
NGC 6251 is a luminous radio galaxy ~104 Mpc away that was detected significantly with the Fermi Gamma-ray Space Telescope, and before that with EGRET (onboard the Compton Gamma-ray Observatory). Diff...

2011/9/15
Abstract: Let $X$ be a smooth hypersurface of degree $d$ in $\CP^3$. By totally algebraic calculations, we prove that on the third Demailly-Semple jet bundle $X_3$ of $X$, the bundle $\ocal_{X_3}(1)$ ...
