Iodine—A Potential Antioxidant and the Role of Iodine/Iodide in Health and Disease  [PDF]
Rudolf Winkler
Natural Science (NS) , 2015, DOI: 10.4236/ns.2015.712055
Abstract: In human physiology, iodine is primarily noted for its role in thyroid function and less so for its many extrathyroidal functions, particularly those based on its antioxidant properties. As I- it protects against free radicals and peroxides. This is seen in vitro in decreased depolymerization of hyaluronic acid and increased antioxidant status in human serum, and in vivo in increased antioxidant enzyme activities and decreases of malondialdehyde and peroxides. It could be shown or deduced that balneotherapeutic applications of iodine/iodide have a positive effect on cardiocirculatory diseases, respiratory disorders, some eye diseases (dry eye, cataract, age-related macular degeneration), and other degenerative diseases connected with increased oxidative stress that are also treated by balneotherapy.


Prevention of Iatrogenic Cervical Cancer  [PDF]
Rudolf Klimek
Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.514109
Abstract: Cervical carcinogenesis consists of natural occurring spontaneous cellular processes which may lead to self-organized dissipative structures of cervical cancers what was first explained in 1977 after several years of my biochemical, biophysical, hormonal and clinical studies. That was possible thanks to monograph “Biochemie der Tumoren” written in 1942 by Nobel Prize winner H. von Euler with my master Prof. B. Skarzynski. Today I express my gratitude to Nobelist Harald zur Hausen and his team for they discovered the nuclide sequences of HPV in genomes of cervical cancer cells which opened the possibility to describe the causal role of information in formula of reality. Vaccines built from the protein capsid of HPV have proved only the pathogenic information about the virus because of its lack of DNAs. All the theories of carcinogenesis have properly described this event from methodologically different point of view. The point is that one should understand the thermodynamic rules underlying each of these approaches. Neoplasms are self-organized from the cells of the patient, who did not provide the necessary conditions for cellular metabolism as defined in the moment of appearance of its zygote. In light of medical thermodynamics all oncogenic factors can divide into sufficient or necessary to events for creating a dissipathogenic cellular status. Cervical cancer is a tumor associated with the human papillomavirus as only its pathogenic dissipathogenic factors, but the genome of cervical carcinoma cells maybe the original source of many types of HPV from the peeled off cancer cells of the uterine cervix. Many things are known to increase the risk of carcinogenesis which as a natural process is an alternative of cellular or social death. Neoplasm cell is an effect of carcinogenesis, but not a causal point at which it begins its existence.

Ceramic Methyltrioxorhenium

Physics , 2006, DOI: 10.1103/PhysRevB.73.165113
Abstract: The metal oxide polymeric methyltrioxorhenium [(CH3)xReO3] is an unique epresentative of a layered inherent conducting organometallic polymer which adopts the structural motifs of classical perovskites in two dimensions (2D) in form of methyl-deficient, corner-sharing ReO5(CH3) octahedra. In order to improve the characteristics of polymeric methyltrioxorhenium with respect to its physical properties and potential usage as an inherentconducting polymer we tried to optimise the synthetic routes of polymeric modifications of 1 to obtain a sintered ceramic material, denoted ceramic MTO. Ceramic MTO formed in a solvent-free synthesis via auto-polymerisation and subsequent sintering processing displays clearly different mechanical and physical properties from polymeric MTO synthesised in aqueous solution. Ceramic MTO is shown to display activated Re-C and Re=O bonds relative to MTO. These electronic and structural characteristics of ceramic MTO are also reflected by a different chemical reactivity compared with its monomeric parent compound. First examples of the unprecedented reactivity of ceramic MTO in the field of amine oxidations are shown - results which warrant further exploitation.
Towards Real-World Applications of Online Learning Spiral Recurrent Neural Networks  [PDF]
Rudolf SOLLACHER, Huaien GAO
Journal of Intelligent Learning Systems and Applications (JILSA) , 2009, DOI: 10.4236/jilsa.2009.11001
Abstract: Distributed intelligent systems like self-organizing wireless sensor and actuator networks are supposed to work mostly autonomous even under changing environmental conditions. This requires robust and efficient self-learning capabilities implementable on embedded systems with limited memory and computational power. We present a new solution called Spiral Recurrent Neural Networks (SpiralRNN) with an online learning based on an extended Kalman filter and gradients as in Real Time Recurrent Learning. We illustrate its stability and performance using artificial and real-life time series and compare its prediction performance to other approaches. SpiralRNNs perform very stable and show an ac-curacy which is superior or similar to other state-of-the-art approaches. In a memory capacity evaluation the number of simultaneously memorized and accurately retrievable trajectories of fixed length was counted. This capacity turned out to be a linear function of the size of the recurrent hidden layer, with a memory-to-size ratio of 0.64 for shorter trajectories and 0.31 for longer trajectories. Finally, we describe two potential applications in building automation and logistics and report on an implementation of online learning SpiralRNN on a wireless sensor platform under the TinyOS embedded operating system.
Computer simulation of the stochastic dynamics of super-paramagnetic particles in ferrofluids
Scherer, Claudio;
Brazilian Journal of Physics , 2006, DOI: 10.1590/S0103-97332006000500018
Abstract: several papers have been written on the complex problem of the stochastic dynamics of the magnetic moments of super-paramagnetic particles, simultaneously with the stochastic rotation of these colloidal particles in a ferrofluid [1-3]. none of these works, however, is sufficiently general and conveniently simple and clear to be used in sumulational works to appropriately describe the experimental super-paramagntetic resonance lines. we have a new proposal for the equations of rotational motion, which is appropriate for simulations. those equations are stochastic differential equations with multiplicative noise. therefore, they have to be interpreted as stratonovich-langevin equations and the roles of stochastic calculus have to be used in the simulations. for this reason we will briefly present the essence of the numerical algorithms used in the solutions of stratonovich equations. finally, the simulational results for the magnetic response functions, and the corresponding dynamic susceptibilities, will be shown and their consequences will be analyzed.
Stochastic Molecular Dynamics of colloidal particles
Scherer, Claudio;
Brazilian Journal of Physics , 2004, DOI: 10.1590/S0103-97332004000300023
Abstract: colloidal particles move in the carrier liquid under the action of several forces and torques. when the particles carry a dipole moment, electric or magnetic, as in ferrofluids, the rotational and translational motions are coupled because the field on a particle depends on the spatial and directional distribution of the others and the force and torque on it depends on the field. moreover, there is brownian, as well as dissipative forces and torques on each particle. consequently, the numerical solution of the equations of motion requires, besides the techniques of classical molecular dynamics, those of stochastic dynamics. the algorithm is explained in some detail and applied on a typical ferrofluid. for different values of the temperature, the possibility of the formation of structures is examined.
Recent Progress in Effective Field Theory in the One-Nucleon Sector
Scherer, Stefan
High Energy Physics - Phenomenology , 2007, DOI: 10.1007/s00601-008-0229-3
Abstract: Chiral perturbation theory (ChPT) is the effective field theory of the strong interactions at low energies. We will address the issue of a consistent power counting scheme in a manifestly Lorentz-invariant formulation of baryon ChPT. As applications we show how the inclusion of vector and axial-vector mesons in the calculation of the nucleon electromagnetic and axial form factors, respectively, lead to an improved description of the empirical data. Finally, we will outline a systematic implementation of the Delta(1232) resonance into the effective field theory program.
