Automatic shot boundary detection has been an active research area for nearly a decade and has led to high performance detection algorithms for hard cuts, fades and wipes. Reliable dissolve detection, however, is still an unsolved problem. In this paper, we present the first robust and reliable dissolve detection system. A detection rate of 69% was achieved while reducing the false alarm rate t...

It has been shown that hydrogen and oxygen atoms cannot be present in the open pores of crystal lattices base metals casting alloys. The solubility gases liquid alloys is a nanostructured process. Hydrogen melts are adsorbed by basic metal elemental nanocrystals. Nitrogen dissolves iron, nickel chromium not atomic form, but composition elementary nanocrystals nitride molecules. After deoxidatio...

Metallic gallium dissolves slowly in dilute mineral acids but rapidly in aqua regia and concentrated sodium hydroxide. In its compounds, the valency is +3. Its oxygen compounds resemble those of aluminum in that there are highand lowtemperature forms of Ga2O3 and two hydroxides, Ga(OH)3 and GaO·OH. Substances which lower the hydrogen ion concentration throw down a white gelatinous precipitate f...

We report the formation of solvent-mediated gels as well as their hierarchical structures and rheological properties. The gelator used is a hybrid with a molecular structure of cholesterol-polyoxometalate-cholesterol, in which the cholesterol dissolves well in toluene and N,N-dimethylformamide (DMF), whereas the polyoxometalate cluster dissolves only in DMF. These solubility differences enable ...

In this paper, we present a novel approach for clipbased key frame extraction. Our framework allows both clips with subtle changes as well as clips containing rapid shot changes, fades and dissolves to be well approximated. We show that creating key frame video abstractions can be achieved by transforming each frame of a video sequence into an eigenspace and then clustering this space using Gau...

Video shot boundary detection is a fundamental step in video indexing and retrieval. There are a number of different types of transitions or boundaries between shots. Most shot change detection algorithms can detect abrupt transitions without difficulty. However, gradual transitions usually consist of wipes, fades, dissolves and computergenerated effects, so it is much more difficult for us to ...

Nanoparticle Drug Delivery The encapsulation of nanoparticles in hydroxypropyl methyl cellulose is key to treat colorectal cancer through oral administration. In article 2202672 by Ilaria Rea, Hélder A. Santos, and co-workers, gelatin-coated diatomite loaded with galunisertib are functionalized an anti-L1-CAM antibody that targets metastatic colon cells. These then encapsulated a gastro-resista...

A Gleeble thermo-mechanical simulator was used to simulate the welds of duplex stainless steel S32101. micro-precipitate chromium-nitride and its surroundings in simulated analyzed detail by SEM/AES EC-AFM. The AES analysis revealed that a chromium-depleted area is present γ phase near chromium-nitrides precipitated at α/γ grain boundary. EC-AFM observation preferentially dissolves from area.

Mineral weathering in soils is an important source of many nutrients to forest ecosystems. Apatite, a Ca phosphate mineral, occurs in trace amounts in virtually all igneous and metamorphic rocks and is often found as small mineral inclusions in more weathering-resistant silicate minerals. To better understand the distribution of apatite in soils and its exposure to soil solutions, a sequential ...
