The control of heart rate by the autonomic nervous system was investigated in conscious human subjects by observing the effects of /3-adrenergic blockade with propranolol, of parasympathetic blockade with atropine, and of combined sympathetic and parasympathetic blockade. The increase in heart rate with mild exercise in supine men was mediated predominantly by a decrease in parasympathetic acti...

The security of RSA depends critically on the inability of an adversary to compute private key from the public key. The problem of computing private key from public key is equivalent to the problem of factoring n into its prime factors. Therefore it is important for the RSA user to select prime numbers in such a way that the problem of factoring n is computationally infeasible for an adversary....

Polyploidization is a part of the normal developmental process leading to platelet production during megakaryocyte (MK) differentiation. Ploidization is mainly involved in cell enlargement, but it is not clear whether gene expression is modified during MK ploidization. In this study, human MKs were grown from CD34(+) cells in the presence of thrombopoietin and sorted according to their ploidy l...

Recording, storage, editing and reproduction of audio signals have compensated some principles of sound perception and changed the human habits of listening. This paper reflects on these changes from an artists point of view. It discusses the idea of transformation and re-mixing of sound in real-time and its use in intermedia art projects.

This paper presents some selected use cases for self-organisation in wireless networks, namely on selfoptimisation (Home eNodeB and Load Balancing) and selfhealing (Cell Outage Management). Furthermore an approach to identify interrelationships between these use cases is presented and an example for parameter correlation is given. The paper thereby provides results that have been achieved withi...

Cancer progression is associated with activation of blood coagulation. Blood coagulation process, platelet hemostasis and hemorheological properties were evaluated in patients with solid tumors (n = 27) before and after surgery and in healthy control (n = 20). The main features of blood coagulation process in cancer patients were elevated intensity and shortened period of contact phase of coagu...

The characterization of many objects involves the determination of a basic set of particle size measures derived mainly from scattering and transport property measurements. For polymers, these basic properties include the radius of gyration Rg, hydrodynamic radius Rh, intrinsic viscosity [η], and sedimentation coefficient S, and for conductive particles, the electric polarizability tensor αE an...
