Normal functioning of the heart is dependent on its ability both to contract and relax. Heart contraction is a complex process that is initiated by an increase in intracellular calcium, which results in myosin binding to actin and myosin movement of the actin filament. Relaxation is reliant on removal of calcium from the contractile filaments, which in turn is dependent on the availability of A...

Hydrodynamics describes the low-frequency, long-wavelength behavior of a system that is disturbed from equilibrium. When a system is disturbed from equilibrium, some quantities and parameters decay very quickly back to their equilibrium state, while others take a long time to relax [1]. Con­ served quantities, such as particle number, momentum, and energy, take a long time to relax to equilibri...

One of the main aspects in the consumer behavior is the concept of involvement because it influences the decision rules used by tourists to reach the final decision. An empirical study of 600 international tourists reveals that motivation to relax, influences tourists’ involvement with the trip. A structural model shows that when tourists are motivated to relax they get directly more involved w...

This paper describes the use of a general purpose distributed object support platform, including an advanced action model, to support Computer Aided Design (CAD) applications. In particular, it describes the use of the Amadeus/RelaX platform to support the DASSY tool interface which, in turn, supports a range of cooperating CAD tools. The paper provides an overview of the Amadeus/RelaX platform...

As the area of Functional Encryption (FE) has grown in importance, the landscape of its security definitions has become increasingly cluttered. Currently prevalent definitions are largely restricted to data privacy, and are broadly categorized as indistinguishability (IND) style or simulation (SIM) style, where the former are known to be insufficient and the latter are known to be unachievable ...

The need for achieving higher data rates in underwater acoustic communications leverages the use of multi-input multi-output (MIMO) schemes. In this paper two key issues regarding the design of a MIMO communications system, namely, channel estimation and symbol detection, are addressed. To enhance channel estimation performance, a cyclic approach for designing training sequences and a channel e...
