We study the EPR-type correlations from the perspective of the relational interpretation of quantum mechanics. We argue that these correlations do not entail any form of “non-locality”, when viewed in the context of this interpretation. The abandonment of strict Einstein realism implied by the relational stance permits to reconcile quantum mechanics, completeness, (operationally defined) separa...
We give a simple non-mathematical explanation of Bell’s inequality. Using the inequality, we show how the results of Einstein-Podolsky-Rosen (EPR) experiments violate the principle of strong locality, also known as local causality. This indicates, given some reasonable-sounding assumptions, that some sort of faster-than-light influence is present in nature. We discuss the implications, emphasiz...
Abstract Experimentally monitoring the dynamics of a physical system, one cannot possibly resolve all microstates or transitions between them. Theoretically, these partially observed systems are modeled by considering only states and while rest hidden, merging into single mesostate, decimating unobserved states. The deviation system from thermal equilibrium can be characterized non-zero value e...
The sympathetic and pressor responses to exercise are exaggerated in hypertension. Evidence suggests that an overactive exercise pressor reflex (EPR) contributes to this abnormal responsiveness. The mechanisms underlying this EPR overactivity are poorly understood. An increasing body of evidence suggests that aldosterone and excessive salt intake play a role in regulating resting sympathetic ac...
Sucrose and common household sugars (e.g. cane) have been studied as dosemeters for a wide variety of applications. However, previous studies of the post-irradiation time dependence of irradiated sugar did not include an electron paramagnetic resonance (EPR) reference material. This work employs synthetic ruby as an EPR reference material to remove significant spectrometer/environmental influen...
to cope with the urban congestion problem resulted from rapid urbanization some cities are successfully using electronic road pricing policy as a demand management measure. in 1982, hong kong governmenttook initiative to experiment electronic road pricing in hong kong. though, the project outcome reveals that electronic road pricing could bring tremendous economic, social and environmental bene...
Introduction EPR was the first spectroscopic method other than UV/visible spectroscopy to be applied systematically to investigations of the structure and functioning of metalloenzymes. The first such EPR studies of xanthine oxidase were reported in 1959 [l]. Since one reduced state of each of the four redox-active centres in the molecule is EPRactive, there is obviously considerable potential ...
Although the sensitivity and dynamic range of EPR are high, the precision of concentration measurements has often been low. Consequently, EPR spectroscopy has a reputation as a rather nonquantitative method. Interlaboratory comparisons of signal area measurements many years ago yielded very discouraging results (1). Since then there have been important improvements in instrumentation and useful...
Electron paramagnetic resonance (EPR) spectroscopy may be applied to examine interactions of melanin with metal ions and drugs. In this work EPR method was used to examination of changes in free radical system of DOPA-melanin--the model eumelanin after complexing with diamagnetic cadmium(II) ions. Cadmium(II) may affect free radicals in melanin and drugs binding by this polymer, so the knowledg...
