De novo NAD+ synthesis enhances mitochondrial function and improves health
Nature, 2018 Nicotinamide adenine dinucleotide (NAD+) is a co-substrate for several enzymes, including the sirtuin family of NAD+-dependent protein deacylases. Beneficial effects of increased NAD+ levels and sirtuin activation on mitochondrial homeostasis, organismal

Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Alzheimer’s disease (AD) is the most common form of dementia, and there is no cure. DNA repair activity is deficient in AD patient brains, especially DNA polymerase β (Polβ), a key protein in DNA base excision.

Numerical solvers and cryptanalysis
Journal of Mathematical Cryptology, 2009 In this paper, we present an approach to apply numerical methods in the cryptanalysis of modern cryptographic algorithms. We focus on the stream cipher Trivium. It is a stream cipher recommended by the eStream project in the hardware category.

On the sensitivities dependence in non-autonomous dynamical systems [PDF]
arXiv, 2016 For discrete autonomous dynamical systems (ADS) $(X, d, f)$, it was found that in the three conditions defining Devaney chaos, topological transitivity and dense periodic points together imply sensitive dependence on initial condition(Banks, Brooks, Cairns, Davis and Stacey, 1992). In this paper, the result of Banks et al.

The Žďár nad Sázavou meteorite fall: Fireball trajectory, photometry, dynamics, fragmentation, orbit, and meteorite recovery [PDF]
, 2019 We report a comprehensive analysis of the instrumentally observed meteorite fall \v{Z}\v{d}\'ar nad S\'azavou, which occurred in the Czech Republic on 9 December 2014 at 16:16:45-54 UT. The original meteoroid with an estimated initial mass of 150 kg entered the atmosphere with a speed of 21.89 km/s and began a luminous trajectory at an altitude of 98 ...

De novo NAD+ biosynthetic impairment in acute kidney injury in humans
Nature Network Boston, 2018 Nicotinamide adenine dinucleotide (NAD+) extends longevity in experimental organisms, raising interest in its impact on human health. De novo NAD+ biosynthesis from tryptophan is evolutionarily conserved yet considered supplanted among higher species by ...
