Guidance Stabilization of Satellites Using the Geomagnetic Field
International Journal of Aerospace Engineering, 2012 In the last years the small satellites have played an important role in the technological development. The attractive short period of design and low cost of them and the capacity to solve problems that are usually considered as problems to big and ...

On modeling blockchain-enabled economic networks as stochastic dynamical systems
Applied Network Science, 2020 Blockchain networks have attracted tremendous attention for creating cryptocurrencies and decentralized economies built on peer-to-peer protocols. However, the complex nature of the dynamics and feedback mechanisms within these economic networks has ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface
FEBS Open Bio, EarlyView.HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

FEBS Open Bio, EarlyView.We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

Numerical Construction of Viable Sets for Autonomous Conflict Control Systems
Mathematics, 2014 A conflict control system with state constraints is under consideration. A method for finding viability kernels (the largest subsets of state constraints where the system can be confined) is proposed.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Optimal control and differential games with measures
Nonlinear Analysis: Theory, Methods & Applications, 1993 The authors discuss optimal control and 2-player differential games, when the disturbances are modelled by a general Radon measure term inside the dynamic, and with a related cost in the payoff: \[ P_{t,x,m}(\zeta,\mu)= \int^ T_ t h_ 1(r,\xi(n),\zeta(r))dr+ \int_{[t,T]} h_ 2(t,\zeta(r)) d\mu(r).
