Gamma band response to visual stimulation in humans has been observed to have both burst and resonance properties. Amplitude modulation of gamma activity at low frequencies has been seen in rat hippocampus and modeled in a number of forms. Significant amplitude modulation (p=0.05) of 33 Hz gamma frequency activity at the frequency of an 8 1/3 Hz photic driving stimulus, which also produced stro...
The relation between the violation of Lorentz invariance and the dynamical effects in high energy gamma rays production is discussed. By using the framework of noncommutative classical electrodynamics, it is shown that full dynamical calculations are required to put bounds on the Lorentz violating scale by the phenomenological analysis of these processes as, for example, the synchrotron radiati...
We study a quasibound state of a delta -kicked rotor with absorbing boundaries focusing on the nature of the dynamical localization in open quantum systems. The localization lengths xi of lossy quasibound states located near the absorbing boundaries decrease as they approach the boundary while the corresponding decay rates Gamma are dramatically enhanced. We find the relation xi approximately G...
We report on the results of R-band observations of the error box of the g-ray burst of 1997 August 28 made between 4 hr and 8 days after this burst occurred. No counterpart was found varying by more than 0.2 mag down to . We discuss the consequences of this nondetection for relativistic blast wave models of g-ray R 5 23.8 bursts and the possible effect of redshift on the relation between optica...
A dose of approximately 8,400 RAD noticeably lowered the number of viable cysts of E. histolytica in a clear, saline suspension, as calculated by the Most Probable Number method. Doses of approximately 16,700 RAD and more destroyed more than 99% of viable cysts. The relation between increasing cyst mortality and increasing gamma-ray dosage is represented by a logarithmic straight line. A differ...
We present a procedure to link the deformation parameter $\ensuremath{\beta}$ of generalized uncertainty principle (GUP) two free parameters $\stackrel{\texttildelow{}}{\ensuremath{\omega}}$ and $\ensuremath{\gamma}$ running Newtonian coupling constant asymptotically safe gravity program. To this aim, we compute Hawking temperature black hole in different ways. The first way involves use GUP pl...
Recent numerical simulations of MHD jets from accretion disks are briefly reviewed with emphasis on the scaling law for jet speed and the role of magnetic reconnection in relation to time variability in accretion disks, jets, and flares. On the basis of these studies, possible interpretation is given on why statistical properties of peak intensity, peak interval, and peak duration of gamma ray ...
Widespread synchronous oscillatory activity, particularly in the gamma ('40 Hz') band, has been postulated to exist in the brain as a mechanism underlying binding. A new method of examining phase synchronicity across multiple electrode sites in specific EEG frequency bands as a function of time was employed, in a conventional cognitive ERP paradigm in 40 normal subjects. A significant late post...
Sensitivity of the tonic stretch reflex (TSR) of biceps brachii in normal man was measured at different levels of voluntary contraction before and after gamma efferent nerve fibres were selectively blocked by infiltration of dilute procaine. The procaine infiltration reduced TSR sensitivity to one half of its control value. It had no effect, however, on the slope of the relation between TSR gai...
Two major antigenic fragments were obtained from various purified gamma-globulin preparations after papain treatment. One, the F component, had a mobility faster than the original gamma-globulin and the second, the S component, had a slower mobility. Similar F and S components were also obtained with certain homogeneous myeloma proteins which were closely related to gamma-globulin immunological...
