, 2013 The location of warm dust producing the mid-infrared (MIR) emission in type 1 active galactic nuclei (AGNs) is complex and not yet fully known. We explore this problem by studying how the MIR covering factor (CF_(MIR) = L_(MIR)/L_(bol)) correlates with ...

Region tracking with narrow perception of background
, 2011 International audienceWe address the problem of object tracking within image sequences through region-based energy minimization. A common underlying assumption in region tracking is that color statistics can be confidently estimated in a global manner ...

Molecularly Dissipative Liquid Crystal Elastomer Foams for Impact and Vibration Attenuation
Advanced Functional Materials, EarlyView.Liquid crystal elastomer foams integrate cellular deformation with mesogen reorientation to create a dual‐scale energy dissipation mechanism. Progressive pore collapse absorbs mechanical loads, while stress‐induced mesogen reorientation provides additional damping, resulting in reduced impact transmission and broadband suppression of vibrational ...

Resue firing and dilution control in narrow vein mining [PDF]
, 2008 Mining of narrow vein mineralisation, invariably depending on the mining method selected, involves the extraction of both ore and waste rock. The level to which mining of waste rock can be minimised depends on numerous factors, but patticularly the ...

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride
Advanced Functional Materials, EarlyView.Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Formal statement of the special principle of relativity [PDF]
, 2013 While there is a longstanding discussion about the interpretation of the extended, general principle of relativity, there seems to be a consensus that the special principle of relativity is absolutely clear and unproblematic.

Narrow band region approach for active contours and surfaces
, 2007 International audienceWe introduce a narrow band region approach for explicit deformable models in the perspective of 2D and 3D image segmentation. Embedding a region term into the evolution process, we derive a general framework which is applied both on

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells
Advanced Functional Materials, EarlyView.In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Advanced Functional Materials, EarlyView.Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...
