Context-aware hand poses classifying on images and video-sequences using a combination of wavelet transforms, PCA and neural networks

EAI Endorsed Transactions on Context-aware Systems and Applications, 2017
In this paper we propose novel context-aware algorithms for hand poses classifying on images and video-sequences. The proposed hand poses classifying on images algorithm based on Viola-Jones method, wavelet transform, PCA and neural networks.

Acetyl-L-carnitine flux to lipids in cells estimated using isotopomer spectral analysis

Journal of Lipid Research, 1997
Acetyl-L-carnitine is known as a reservoir of activated acetyl units and as a modulator of metabolic function. The objective of this study was to quantify the fate of the acetyl moiety of acetyl-L-carnitine in lipogenic pathways.

Translational pharmacology of an inhaled small molecule αvβ6 integrin inhibitor for idiopathic pulmonary fibrosis

Nature Communications, 2020
The αvβ6 integrin is key in activating the pro-fibrotic cytokine TGFβ in idiopathic pulmonary fibrosis. Here, the authors show an inhaled small molecule αvβ6 inhibitor GSK3008348 induces prolonged inhibition of TGFβ signaling pathways in human and murine

Adenosine A_2A receptor binding profile of two antagonists, ST1535 and KW6002: consideration on the presence of atypical adenosine A_2A binding sites

Frontiers in Psychiatry, 2010
Adenosine A2A receptors seem to exist in typical (more in striatum) and atypical (more in hippocampus and cortex) subtypes. In the present study, we investigated the affinity of two adenosine A2A receptor antagonists, ST1535 [2 butyl -9-methyl-8-(2H-1,2 ...

The $\tau$ neutrino as a Majorana particle [PDF]

, 1993
A Majorana mass term for the $\tau$ neutrino would induce neutrino - antineutrino mixing and thereby a process which violates fermion number by two units.
