    The central tendency relationships between earthquakes, quantum fluctuations, and the human brain

    Get PDF
    Physical phenomena occur within a complex manifold of interactions from small scale quantum to large scale energies. These random interactions appear to conform to the central limit theorem, however prediction of these events suggest a non-local factor is typically involved. Data were compiled from a random number generator that utilizes quantum electron tunneling, a photomultiplier tube measuring background photon emissions (~10-11 W/m2), earthquakes recorded by USGS Advanced National Seismic System, and from a database of human electroencephalographic recordings. The data indicated temporal and spatial relationships, suggesting the causality of physical phenomena and the associated entropy conforms to the central limit theorem by means of variable distribution of occurrence.Master of Arts in Psychology (M.A.

    Correlations between a New Daily Global Indicator of Human Behavior, Threshold Seismicity, and Solar Activity: Congruence of Energy and Implications

    We correlated the daily average energy per earthquake for global seismicity within successive 1 M increments 1 0 to 6 0 M solar activity as defined by Solar Flux Units SFU and a new indices for Reports of Human Conflict Behavior for the years 2009 through 2013 1 826 days Events associated with intent e g mobilization and preparation for confrontation were positively correlated only with the average energy per event for 0 01 to 1 M seismic events and negatively correlated with SFU The statistical significance of this seismic-behavior correlation was no longer significant statistically if the shared variance with solar activity was first removed Actual events of force and confrontation displayed the opposite relation positive correlation with SFU and negative correlation with only earthquake energies in this magnitude range The shared variance between the behavioural categories and geophysical variables ranged between 4 to 10 Lag lead correlations indicated that the daily concordance expanded to about three days before or after the behavioural events In particular average earthquake energies peaked 3 days before the behaviors associated with intent for conflic

    We consider the symmetric simple exclusion process in the interval \La_N:=[-N,N]\cap\mathbb Z with births and deaths taking place respectively on suitable boundary intervals I+I_+ and I−I_-, as introduced in De Masi et al. (J. Stat. Phys. 2011). We study the stationary measure density profile in the limit $N\to\infty

    Acceleration of Radiative Decay of Photon Counts With Increasing Numbers of Measurement Units: A Potential Large Scale Negative Zeno Effect That Matches With Lorentz Contraction and Photon Acceleration Durations

    Get PDF
    The reverse Zeno effect whereby an unstable quantum state associated with radiative decay is accelerated by frequent measurements was demonstrated experimentally for numbers of spontaneous photons in a 3 m3 hyperdark chamber during the 60 s following a burst of applied photons. Numbers of photon counts were measured from one digital photomultiplier unit when either 1 (the reference) or 2, 3, or 4 units were measuring simultaneously. There was a median decrease of 50 photons per s with the addition of each additional simultaneous measurement by another unit. The energy was ~ 10-17 J per s and is equivalent to a wavelength of 10 nm. This quantity is equivalent to the energy of one neuron in the human brain displaying its upper limit (~1 kHz).  The results suggest that this increment of energy may be a standard quantity that reflects the numbers of measurements by similar photoelectric currents to the decay of a single photon burst. The approximately 30 to 40 s required for the decay of photons per unit to inflect towards asymptote is consistent with the solution for the Lorentz contraction for the shift in electron mass-energy (10-17 J) with a wavelength of ~10 nm. The 30 to 40 s value is a solution for several applications to novel calculations involving fundamental parameters within the structure of space-time

    MicroVolt Variations of The Human Brain (Quantitative Electroencephalography) Display Differential Torque Effects During West-East versus North-South Orientation in the Geomagnetic Field

    Get PDF
    The human brain was assumed to be an elliptical electric dipole. Repeated quantitative electroencephalographic measurements over several weeks were completed for a single subject who sat in either a magnetic eastward or magnetic southward direction. The predicted potential difference equivalence for the torque while facing perpendicular (west-to-east) to the northward component of the geomagnetic field (relative to facing south) was 4 μV. The actual measurement was 10 μV. The oscillation frequency around the central equilibrium based upon the summed units of neuronal processes within the cerebral cortices for the moment of inertia was 1 to 2 ms which are the boundaries for the action potential of axons and the latencies for diffusion of neurotransmitters. The calculated additional energy available to each neuron within the human cerebrum during the torque condition was ~10-20 J which is the same order of magnitude as the energy associated with action potentials, resting membrane potentials, and ligand-receptor binding. It is also the basic energy at the level of the neuronal cell membrane that originates from gravitational forces upon a single cell and the local expression of the uniaxial magnetic anisotropic constant for ferritin which occurs in the brain. These results indicate that the more complex electrophysiological functions that are strongly correlated with cognitive and related human properties can be described by basic physics and may respond to specific geomagnetic spatial orientation

    Current reservoirs in the simple exclusion process

    Full text link
    We consider the symmetric simple exclusion process in the interval [−N,N][-N,N] with additional birth and death processes respectively on (N−K,N](N-K,N], K>0K>0, and [−N,−N+K)[-N,-N+K). The exclusion is speeded up by a factor N2N^2, births and deaths by a factor NN. Assuming propagation of chaos (a property proved in a companion paper "Truncated correlations in the stirring process with births and deaths") we prove convergence in the limit N→∞N\to \infty to the linear heat equation with Dirichlet condition on the boundaries; the boundary conditions however are not known a priori, they are obtained by solving a non linear equation. The model simulates mass transport with current reservoirs at the boundaries and the Fourier law is proved to hold

    Stochastic perturbations of convex billiards

    Get PDF
    We consider a strictly convex billiard table with C 2 boundary, with the dynamics subjected to random perturbations. Each time the billiard ball hits the boundary its reflection angle has a random perturbation. The perturbation distribution corresponds to the physical situation where either the scale of the surface irregularities is smaller than but comparable to the diameter of the reflected object, or the billiard ball is not perfectly rigid. We prove that for a large class of such perturbations the resulting Markov chain is uniformly ergodic, although this is not true in general.Fil: Markarian, R.. Universidad de la Republica.

    Secretion of ligninolytic enzymes and mineralization of 14C-ring-labeled synthetic lignin by 3 Phlebia tremellosa strains

    Get PDF
    Production of ligninolytic enzymes by three strains of the white rot fungus Phlebia tremellosa (syn. Merulius tremellosus) was studied in bioreactor cultivation under nitrogen-limiting conditions. The Mn(II) concentration of the growth medium strongly affected the secretion patterns of lignin peroxidase and laccase. Two major lignin peroxidase isoenzymes were expressed in all strains. In addition, laccase and glyoxal oxidase were purified and characterized in one strain of P. tremellosa. In contrast, manganese peroxidase was not found in fast protein liquid chromatography profiles of extracellular proteins under either low (2.4 µM) or elevated (24 and 120 µM) Mn(II) concentrations. However, H2O2- and Mn-dependent phenol red-oxidizing activity was detected in cultures supplemented with higher Mn(II) levels. Mineralization rates of 14C-ring-labelled synthetic lignin (i.e., dehydrogenation polymerizate) by all strains under a low basal Mn(II) level were similar to those obtained for Phanerochaete chrysosporium and Phlebia radiata. A high manganese concentration repressed the evolution of 14CO2 even when a chelating agent, sodium malonate, was included in the medium
