A Weighted Guided Filtering-Based Multidomain Fusion Destriping Method

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
An infrared camera is affected by the photon effect, temperature changes, time drift, and other factors when operating in orbit, which makes the ground nonuniformity correction coefficient invalid, resulting in nonuniformity stripes in the infrared ...

Mid-Infrared Colors of Dwarf Galaxies: Young Starbursts Mimicking Active Galactic Nuclei

open access: yes, 2016
Searching for active galactic nuclei (AGN) in dwarf galaxies is important for our understanding of the seed black holes that formed in the early Universe. Here, we test infrared selection methods for AGN activity at low galaxy masses.

Profilometry‐Based Indentation Plastometry Testing of Tungsten at High Temperature

open access: yesAdvanced Engineering Materials, EarlyView.
Profilometry‐based indentation plastometry (PIP) allows extraction of stress‐strain curves from indent profiles. Tungsten is of industrial interest but is brittle at room temperature. It does plastically deform at higher temperatures. Excellent agreement is obtained between the two techniques in this regime, but PIP also gives plasticity ...

High-redshift, Restframe Far-infrared Selected Galaxies [PDF]

open access: yesarXiv, 2006
I discuss our current understanding of the properties and nature of high redshift, far-infrared luminous galaxies selected through their observed-frame submillimeter emission.

Mechanical Behavior and Microstructural Changes Associated with Tensile Deformation above the Martensite Start Temperature during Quenching and Subsequent Partitioning of a Low‐Alloy 37SiB6 Steel

open access: yesAdvanced Engineering Materials, EarlyView.
A new experimental setup, incorporating digital image correlation and infrared thermography in combination with inductive‐conductive heating for precise temperature control, is used to analyze the mechanical behavior and microstructural changes of sheet metal under complex thermomechanical test conditions that represent quench and partitioning ...

A Mid-Infrared Galaxy Atlas (MIGA)

open access: yes, 1999
A mid-infrared atlas of part of the Galactic plane ($75^\circ < l < 148^\circ, b = \pm6^\circ$) has been constructed using HIRES processed infrared data to provide a mid-infrared data set for the Canadian Galactic Plane Survey (CGPS).

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

open access: yesAdvanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Infrared Surveys for AGN [PDF]

open access: yesarXiv, 2002
From the earliest extragalactic infrared studies AGN have shown themselves to be strong infrared sources and IR surveys have revealed new populations of AGN. I briefly review current motivations for AGN surveys in the infrared and results from previous IR surveys.

Observations of ULIRGs with the IRS on Spitzer [PDF]

open access: yes, 2009
Ultraluminous Infrared Galaxies (ULIRGs), those systems with L_(IR) ≥ 10^(12)L_⊙, have the power output of quasars, yet (re-)emit the vast majority of their energy in the far-infrared part of the spectrum.

Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12

open access: yesAdvanced Engineering Materials, EarlyView.
Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.
