HOW DO THE LENGTHS OF THE LEAD LAG TIME BETWEEN STOCKS EVOLVE? TICK-BY-TICK LEVEL MEASUREMENTS ACROSS TWO DECADES

How Do the Lengths of the Lead Lag Time between Stocks Evolve? Tick-by-tick Level Measurements across Two Decades

There has been an extraordinary decrease in order execution time on stock exchanges in the past two decades.A related question is whether there has been a similar reduction in orders of magnitude for the lengths of the lead lag time between stocks.If the answer is affirmative, and the lengths of the lead lag time have long fallen Sunglasses below t

Seismic activity and thermal regime of low temperature fumaroles at Mt. Vesuvius in 2004-2011: distinguishing among seismic, volcanic and hydrological signals

Seismological, soil temperature and hydrological data from Mt.Vesuvius are collected to characterize the present-day activity of the volcanic/hydrothermal system and to detect possible unrest-related phenomena.We present patterns of seismicity and soil temperature in the crater area during the period February 2004-December 2011.The temporal distrib

Graphene-Based Absorber: Tunable, Highly Sensitive, Six-Frequency

Due to the equipartition exciton property of graphene metamaterials, researchers have applied them to the design of absorbers and developed a series of absorbers covering different wavebands (including narrowband and broadband).In this paper, an absorber based Phosphatidylcholine on surface-isotropic excitations was designed with the help of graphe
