We study an important class of feedback controllers that arise in curve tracking problems for robotics. Previous experimental results suggested the robust performance of the control laws under perturbations. Here we use input‐to‐state stability to prove predictable tolerance and safety bounds that ensure robust performance under perturbations and time delays. Our proofs are based on an invarian...

John Bell taught us that quantum mechanics can not be reproduced by noncontextual and local Hidden variable theory. The impossibility of replacing quantum mechanics by non-contextual Hidden Variable Theory can be turned to a impossible coloring pseudo-telepathy game to be played by two distant players. The game can not be won without communication in the classical world. But if the players shar...

We revisit narrow-pipe designs that are in practical use, and their security against preimage attacks. Our results are the best known preimage attacks on Tiger, MD4, and reduced SHA-2, with the result on Tiger being the first cryptanalytic shortcut attack on the full hash function. Our attacks runs in time 2 for finding preimages, and 2 for second-preimages. Both have memory requirement of orde...

intestinal pseudo-obstruction is a condition in which the intestine’s ability to push food through is reduced. it often leads to the dilation of the various parts of the bowel. it can be idiopathic or inherited from a parent, or caused by another disease. we report a rare case of human immunodeficiency virus (hiv) infection in a 3-year-old boy who referred with acute abdominal pain, and was lat...

background: phic31 integrase is a dna site-specific recombinase integrates dna into the chromosomes between the two sites of attb and attp. several pseudo attps have been identified in mammalian genomes with critical features for long-term expression of transgene. in this manuscript, we report a novel intrinsic pseudo attp site named chol1 in the chinese hamster genome implementing an inverse p...

Abstract Phreatic explosions at volcanoes are difficult to forecast but can be locally devastating, as illustrated by the deadly 2019 Whakaari (New Zealand) eruption. Quantifying eruption likelihood is essential for risk calculations that underpin volcano access decisions and disaster response. But estimating probabilities notoriously sudden onset eruptions. Here, we describe two retrospectivel...

Abstract. Despite high potential benefits, the development of seasonal forecasting tools in water sector has been slower than other sectors. Here we assess skill for lakes and reservoirs set up at four sites Australia Europe. These consist coupled hydrological catchment lake models forced with meteorological forecast ensembles to provide probabilistic predictions anomalies discharge, temperatur...

Abstract We apply the Probabilistic Seismic Hazard Analysis (PSHA) and compute Physics-Based Simulations (PBS) of ground motion for three dams in Campotosto area (Central Italy). The dams, which confine an artificial water reservoir feeding hydroelectric power plants, are located active seismic zone between areas that experienced 2009 L’Aquila 2016–2017 Central Italy sequences. probabilistic di...
