TO THE EDITOR: I thank my friends, colleagues, and opponents for their thoughtful submissions (see Ref. 1), which capture the diversity of views concerning the pathophysiological mechanisms of essential hypertension. Many seem to have lodged an each-way bet, invoking parallel sympathetic nervous system and renin-angiotensin system origins. A few seemed to think the question was a silly one and ...

The aim of this paper is to study the influence of the shape of the temperature distribution on the thermoacoustic amplification in an annular thermoacoustic prime mover. An analytical model is presented and the acoustic field in the whole device is computed for an arbitrary temperature distribution. The obtained results demonstrate dependence of the thermoacoustic amplification not only on the...

With the help of time-dependent scattering theory on observable algebra infinitely extended quasifree fermionic chains, we introduce a general class so-called right mover/left mover states which are inspired by nonequilibrium steady for prototypical configuration finite sample coupled to two thermal reservoirs at different temperatures. Under assumption spatial translation invariance, relate 2-...

The unifying scenario fo cosmic evolution is outlined by following the natural changes among radiation, matter and life in standard, big-bang cosmology. Using aspects of non equilibrium thermodynamics, especially energy flow considerations, we argue that it is the contrasting temporal behavior of various energy densities that have given rise to the environments needed for the emergence of galax...

This paper presents an approach to identify hand gestures with muscle activity separated from electromyogram (EMG) using Back Propagation analysis with the goal of using hand gestures for humancomputer interaction. While there are a number of previous reported works where EMG has been used to identify movement, the limitation of these works is that the systems are suitable for gross actions and...

The potential fuel savings of hybrid vehicles strongly depend on the energy management strategy, which distributes the required power between the prime mover and the additional power sources. Here, it is necessary to take into account the efficiencies of the whole propulsion system. In this paper, a novel operating strategy is developed that considers the efficiencies of all major components of...

The removal of the non-return valve from the refrigeration system with a twin screw compressor is realizable by fitting a non-reversing clutch to the prime mover to restrain the reverse rotation of the compressor following shut down. Utilizing a suite of computer programs developed by the authors, the influence of the non-return valve is examined; gas torques under normal running condition and ...

We consider a sequential two-party bargaining game with uncertain information transmission. When the first mover states her demand she does only know the probability with which the second mover will be informed about it. The informed second mover can either accept or reject the offer and payoffs are determined as in the ultimatum game. Otherwise the uninformed second mover states his own demand...
