On energy harvesting for augmented tags
Comptes Rendus. Physique, 2016 Dans cet article, les signaux harmoniques générés par les puces RFID UHF, généralement considérés comme des effets parasites et non utilisés, sont exploités. En effet, les signaux harmoniques sont collectés pour alimenter un circuit supplémentaire associé à un tag RFID passif. Deux approches sont présentées et comparées.

Alkane biosynthesis gene expression and its increased production in recombinant cyanobacteria
FEBS Open Bio, EarlyView.The transcription and mRNA structures of the alkane biosynthesis genes ado/aar were analysed in the representative cyanobacteria PCC 6803 and SK1‐2‐1, which produce C17H36 and C15H32, respectively. PCC 6803 transconjugants carrying these genes showed a 1.8‐ to 2.3‐fold increase in C17H36 production.

FEBS Open Bio, EarlyView.Measuring AMP‐activated protein kinase (AMPK) activity in vitro is crucial for testing AMPK activators or inhibitors with therapeutic potential. Here, we report an enzyme‐linked immunosorbent assay (ELISA)‐based AMPK activity assay with simple steps and high sensitivity, which offers a simple, robust, and cost‐effective alternative to traditional ...

Nonlinear Energy Harvesting Models in Wireless Information and Power Transfer [PDF]
arXiv, 2018 This work compares different linear and nonlinear RF energy harvesting models, including limited or unlimited sensitivity, for simultaneous wireless information and power transfer (SWIPT). The probability of successful SWIPT reception under a family of RF harvesting models is rigorously quantified, using state-of-the-art rectifiers in the context of ...

Comparison of Electromagnetic Energy Harvesters
2019 11th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2019 This paper compares various types of electromagnetic harvesters in terms of their electrical and magnetic features. The harvesters have different flux morphologies and natural frequencies and therefore that can be a superiority for them to use in different applications from the ignition signal to the energy harvester aims for battery-free systems.

FEBS Open Bio, EarlyView.The A3 adenosine receptors (A3ARs) are overexpressed in prostate cancer. AR 292 and AR 357, as A3AR antagonists, are capable of blocking proliferation, modulating the expression of drug transporter genes involved in chemoresistance, ferroptosis, and the hypoxia response, and inducing cell death.
