Objective It is well-known that all living cells emit ultra-weak photon emission (UPE), which is due to byproducts of chemical reactions in cell metabolisms. It has been shown that Reactive Oxygen Species (ROS) in the cells enhances the UPE intensity. The magnitude of such UPE is extremely weak (i.e. a few to 103 photons/ (sec.cm22)), and the detection of such ultra-weak signals is hardly possi...

Abstract Tunnel nanojunctions based on inelastic electron tunneling (IET) have been heralded as a breakthrough for ultra-fast integrated light sources. However, the majority of electrons tend to tunnel through junction elastically, resulting in weak photon-emission power and limited efficiency, which hindered their practical applications date. Resonant has proposed way alleviate this limitation...

The wheat kernels were processed by moistened in water. The spontaneous and water-induced luminescence data (photon counts) were noted with an ultra-weak luminescence (UWL) detector. The following was the features of the data analyzed by the statistical parameters of the spontaneous luminescence and the fitting curves of the water-induced luminescence. The results show that the UWL intensity ri...

The current healthcare system is hampered by a reductionist approach in which diagnostics and interventions focus on a specific target, resulting in medicines that center on generic, static phenomena while excluding inherent dynamic nature of biological processes, let alone psychosocial parameters. In this essay, we present some limitations of the current healthcare system and introduce the nov...

We recently derived, using diagrammatic methods, the leading-order hard photon emission rate in ultra-relativistic plasmas. This requires a correct treatment of multiple scattering effects which limit the coherence length of emitted radiation (the Landau-Pomeranchuk-Migdal effect). In this paper, we provide a more physical derivation of this result, and extend the treatment to the case of gluon...
