Synthesis and Characterization of Sulfonated Poly(Phenylene) Containing a Non-Planar Structure and Dibenzoyl Groups

open access: yesEnergies, 2016
Polymers for application as sulfonated polyphenylene membranes were prepared by nickel-catalyzed carbon-carbon coupling reaction of bis(4-chlorophenyl)-1,2-diphenylethylene (BCD) and 1,4-dichloro-2,5-dibenzoylbenzene (DCBP).

Cloud Optimized Image Format and Compression [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Cloud based image storage and processing requires revaluation of formats and processing methods. For the true value of the massive volumes of earth observation data to be realized, the image data needs to be accessible from the cloud.

Oral Administration of Curcumin Suppresses Production of Matrix Metalloproteinase (MMP)-1 and MMP-3 to Ameliorate Collagen-Induced Arthritis: Inhibition of the PKCĪ“/JNK/c-Jun Pathway

open access: yesJournal of Pharmacological Sciences, 2009
We investigated whether oral administration of curcumin suppressed type II collagen–induced arthritis (CIA) in mice and its effect and mechanism on matrix metalloproteinase (MMP)-1 and MMP-3 production in CIA mice, RA fibroblast-like synoviocytes (FLS ...

Electron choreography at the attosecond time scale

open access: yesNew Journal of Physics, 2021
In this work, we report on coherent control of electron dynamics in atoms via attosecond pulse-shaping. We show that the photoelectron emission from argon gas produced by absorption of an attosecond pulse train (APT) made of odd and even harmonics can be

Moduli induced cogenesis of baryon asymmetry and dark matter

open access: yesPhysics Letters B, 2016
We study a cogenesis mechanism in which the observed baryon asymmetry of the universe and the dark matter abundance can be produced simultaneously at low reheating temperature without violating baryon number in the fundamental interactions. In particular,

Resonant Combustion Start Considering Potential Energy of Free-Piston Engine Generator

open access: yesEnergies, 2020
Free-piston engine generators without a crank mechanism are expected to be used in series hybrid vehicles because of their lower losses. The series hybrid system requires a low starting thrust because the engine frequently starts depending on the battery

Anti-neuroinflammatory Activity of Kamebakaurin From Isodon japonicus via Inhibition of c-Jun NH2-Terminal Kinase and p38 Mitogen-Activated Protein Kinase Pathway in Activated Microglial Cells

open access: yesJournal of Pharmacological Sciences, 2011
.: Compelling evidence supports the notion that the majority of neurodegenerative diseases are associated with microglia-mediated neuroinflammation. Therefore, quelling of microglial activation may lead to neuronal cell survival.
