Using physical unclonable functions for internet-of-thing security cameras
(Springer, 2018)
This paper proposes a low-cost solution to develop IoT security cameras. Integrity and confidentiality of the image data are achieved by cryptographic modules that implement symmetric key-based techniques which are usually ...

Dormant intracellular salmonella enterica serovar typhimurium discriminates among salmonella pathogenicity island 2 effectors to persist inside fibroblasts
(American Society for Microbiology, 2014-01)
Salmonella enterica uses effector proteins delivered by type III secretion systems (TTSS) to colonize eukaryotic cells. Recent in vivo studies have shown that intracellular bacteria activate the TTSS encoded by Salmonella ...

Crystal structure, NIR luminescence and X-ray computed tomography of Nd3+:Ba0.3Lu0.7F2.7 nanospheres
(Royal Society of Chemistry (Great Britain), 2017)
Uniform, hydrophilic 50 nm diameter Nd3+-doped Ba0.3Lu0.7F2.7 nanospheres are synthesized at 120 °C using a singular one-pot method based on the use of ethylene glycol as solvent, in the absence of any additive. The ...

Synthesis of Chondroitin Sulfate Oligosaccharides Using N-(Tetrachlorophthaloyl)- and N-(Trifluoroacetyl)galactosamine Building Blocks
(Wiley-Blackwell, 2014)
We have explored synthetic routes for the preparation of chondroitin sulfate (CS) oligosaccharides based on the use of N-tetrachlorophthaloyl- (N-TCP) and N-trifluoroacetyl-substituted (N-TFA) galactosamine building blocks. ...

Colorimetric energy sensitive scintillator detectors based on luminescent multilayer designs
(Elsevier, 2018)
In this work we present a new concept for energy sensitive radiation-beam scintillator detectors based on a luminescent multilayer design, where each layer within the stack consists of a rare-earth-doped highly transparent ...

FPGA design example for maximum operating frequency measurements
(IEEE Computer Society, 2018)
The best way to learn how to design digital systems at the RT level is to use practical examples. In addition, from a teaching point of view, the more practical they are, the more attractive to students. But for a design ...

Embedded electronic circuits for cryptography, hardware security and true random number generation: an overview
(Wiley-Blackwell, 2017)
We provide an overview of selected crypto-hardware devices, with a special reference to the lightweight electronic implementation of encryption/decryption schemes, hash functions, and true random number generators. In ...

N7-methylguanosine methylation of tRNAs regulates survival to stress in cancer
(Springer Nature, 2023)
Tumour progression and therapy tolerance are highly regulated and complex processes largely dependent on the plasticity of cancer cells and their capacity to respond to stress. The higher plasticity of cancer cells highlights ...

Development of silica‐based biodegradable submicrometric carriers and investigating their characteristics as in vitro delivery vehicles
(MDPI, 2020)
Nanostructured silica (SiO2)-based materials are attractive carriers for the delivery of bioactive compounds into cells. In this study, we developed hollow submicrometric particles composed of SiO2 capsules that were ...
