Omega-3 polyunsaturated fatty acids (PUFA) may modulate autonomic control of the heart because omega-3 PUFA is abundant in the brain and other nervous tissue as well as in cardiac tissue. This might partly explain why omega-3 PUFA offer some protection against sudden cardiac death (SCD). The autonomic nervous system is involved in the pathogenesis of SCD. Heart rate variability (HRV) can be use...

Optimal nutrition is one of the most important determinants of healthier ageing, reducing the risk of disability, maintaining mental and physical functions, and thus preserving and ensuring a better quality of life. Dietary intake and nutrient absorption decline with age, thus increasing the risk of malnutrition, morbidity and mortality. Specific nutrients, particularly long-chain omega-3 polyu...

This study proposes an algorithm detecting atmospheric blocking by extracting topological features of geopotential height data at 500 hPa. The uses flow analysis (TFDA) providing a unique symbolic representation, named the partially cyclically ordered rooted tree (COT) and discrete graph structure, called Reeb graph, to each structurally stable Hamiltonian vector field based on mathematical the...

Given an observable f defined on the phase space of some dynamical system generated by the mapT, we consider the error between the value of the function f(Tnx0) computed at time n along the orbit with initial condition x0, and the value f(Tn x0) of the same observable computed by replacing the map Tn with the composition of maps T(omega)(n)o...oT(omega)1, where each T(omega) is chosen randomly,...

LLE Review, Volume 73 1 Pulsed-laser systems emit optical pulses having a temporal pulse shape characteristic of the particular type of laser design. Advances in technology have produced laser-pulseshaping systems where the laser temporal profile can be specified in advance and controlled to a high degree of accuracy.1–3 A pulse-shaping system has been in operation on OMEGA for several years. T...

We describe a genetic system in which transformation of Streptococcus pneumoniae and Streptococcus sanguis was used to insert recombinant DNA into the conjugative chromosomal element omega (cat tetM) 6001 (omega 6001). The element containing the recombinant DNA was then transferred by conjugation to the chromosome of transformable and nontransformable streptococci. When Escherichia coli plasmid...
