The 2-m robotic Liverpool Telescope (LT) reacted promptly to the high-redshift (z = 4.048) gamma– ray burst GRB 060206. The afterglow was identified automatically and multicolor riz imaging program was triggered without human intervention. Combining our data with those obtained from later follow-ups provides a well-sampled optical light-curve from 5 minutes to >2d after the gamma event. The lig...

Abstract To avoid cross-contamination between different samples, improve the cleaning effect of outer wall inner needle digital PCR detector, and reduce cost solution, jet was simulated by FLUENT software using VOF gas-liquid two-phase flow model PISO algorithm. In a certain range, inlet velocity, solution viscosity, interfacial tension, contact angle are changed to simulate theoretical injecti...

In this paper we use the predicted spatial development of helical structures along an expanding jet to model observed structures and motions in the 3C 120 jet. New results of VLBI imaging of the parsec-scale radio jet in 3C 120 at 5 GHz are examined along with older long term monitoring results at 5 GHz and older results obtained at 22 and 43 GHz. The high frequency observations provide detaile...

We present new details of the structure and morphology of the jets and outflows in HH46/47 as seen in Spitzer infrared images from IRAC and MIPS, reprocessed using the “HiRes” deconvolution technique. HiRes improves the visualization of spatial morphology by enhancing resolution (to sub-arcsec levels in IRAC bands) and removing the contaminating side lobes from bright sources. In addition to sh...

We collected optical and near IR linear polarization data obtained over 20–30 years for a sample of 51 blazars. For each object, we calculated the probability that the distribution of position angles was isotropic. The distribution of these probabilities was sharply peaked, with 27 blazars showing a probability < 15% of an isotropic distribution of position angles. For these 27 objects we defin...

The medium that forms in a heavy-ion collision modifies the properties of jets traversing it. These modifications give substantial information about nature and, therefore, they are one main focuses program at LHC. influence into highly energetic partons depends on correlators Wilson lines, which have been studied perturbation theory and several phenomenological models. Here, we focus antenna co...

We consider a gamma-ray burst (GRB) model based on an anisotropic fireball with an axisymmetric energy distribution of the form ǫ(θ) ∝ θ, and allow for the observer’s viewing direction being at an arbitrary angle θv with respect to the jet axis. This model can reproduce the key features expected from the conventional on-axis uniform jet models, with the novelty that the achromatic break time in...

High-frequency jet ventilation using either a proximal or a distal endotracheal injection site through a triple-lumen endotracheal tube was studied in 10 adult cats. The comparative effects on pulmonary gas exchange, tracheal pressure, heart rate, and blood pressure were examined for each injection site at both high (8-12 pounds per square inch [PSI] and low (5-8 PSI) jet-driving pressures in n...
