Advanced Intelligent Systems, EarlyView.This work presents a magnetic bronchoscopy robot with a novel multi‐segment variable stiffness catheter. This catheter can not only move flexibly in the narrow bronchi but also harden according to the need to provide support. Combined with remote wireless magnetic field drive, it provides a more precise and effective solution for biopsy of deep lung ...

Measuring the star formation rate density from CNOC2 [PDF]
, 2006 This thesis charts the evolution of the Universal Star Formation Rate Density (SFRD) across the redshift range 0.2 < z < 0.6, using the 2nd Canadian Network for Observational Cosmology Survey (CN0C2).

Germanium‐Based Mid‐Infrared Integrated Photonics
Laser &Photonics Reviews, EarlyView.The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Small, EarlyView.This study reports intrinsically stretchable neuromorphic devices that exhibit outstanding mechanical stability while fully preserving their electrical characteristics over 105 repeated deformation cycles under 50% tensile strain. Such robustness is achieved through a rational molecular design strategy that systematically modulates the chain packing of

The radio continuum structure of bright galaxies at 1.4 GHZ. [PDF]
, 1980 The (double) source structure of the radio continuum emission of the more powerful radio sources associated with galaxies is only briefly discussed in Chapter VI. In Chapter VII we gave a fractional luminosity function for these sources. Some evidence is

Radio continuum emission in ring galaxies
The Astronomical Journal, 1980 Radio emission was found in two (Arp 118 and Arp 148) of 27 ring-type galaxies searched with the NRAO interferometer to a detection limit of about 10 mJy at 11.1 cm. These two were also observed at 6 cm with the higher sensitivity and resolution of the VLA.

The global star formation law of galaxies revisited in the radio continuum [PDF]
Science China Physics, Mechanics and Astronomy, 2012 We study the global star formation law - the relation between the gas and star formation rate (SFR) in a sample of 130 local galaxies with infrared (IR) luminosities spanning over three orders of magnitude (10^9-10^12 Lsun), which includes 91 normal spiral galaxies and 39 (ultra)luminous IR galaxies [(U)LIRGs].

A Context‐Aware Decision Support Framework for Scientific Experiment Configuration
Software: Practice and Experience, EarlyView.ABSTRACT Introduction Defining an experimental configuration is a complex decision problem for early‐stage researchers, who must map goals, constraints, and requirements onto datasets, algorithms, and parameter settings that directly affect experimental outcomes.

The Search for Very High Energy γ-rays from Misaligned AGN [PDF]
, 2013 The aim of this work is to study the potential for emission at very high energies (100 GeV) by misaligned active galactic nuclei (AGN) and the future prospects for observations of these objects with the next generation imaging atmospheric Cherenkov ...

Radio continuum polarimetric imaging of high redshift radio galaxies
The Astronomical Journal, 1994 Multifrequency images of total and polarized radio continuum emission from the two high redshift radio galaxies 0902+343 (z = 3.40) and 0647+415 (4C 41.17, z = 3.80) are presented. These images represent the most sensitive polarimetric study of high redshift ratio galaxies to date.
