The IceCube experiment has detected two neutrinos with energies between 1 and 10 PeV. They might have originated from Galactic or extragalactic sources of cosmic rays. In the present work we consider hadronic interactions of the diffuse very high energy cosmic rays with the interstellar matter within our Galaxy to explain the PeV neutrino events detected in IceCube. We also expect PeV gamma ray events along with the PeV neutrino events if the observed PeV neutrinos were produced within our Galaxy in hadronic interactions. PeV gamma rays are unlikely to reach us from sources outside our Galaxy due to pair production with cosmic background radiation fields. We suggest that in future with simultaneous detections of PeV gamma rays and neutrinos it would be possible to distinguish between Galactic and extragalactic origins of very high energy neutrinos. © 2013 Elsevier Ltd.

The steady state of a Brownian particle diffusing in an arbitrary potential under the stochastic resetting mechanism has been studied. We show that there are different classes of nonequilibrium steady states depending on the nature of the potential. In the stable potential landscape, the system attains a well-defined steady state; however, the existence of the steady state for the unstable landscape is constrained. We have also investigated the transient properties of the propagator towards the steady state under the stochastic resetting mechanism. Finally, we have done numerical simulations to verify our analytical results. © 2015 American Physical Society. Source

The present invention relates to an etched optical fiber as force transducer with feedback control, with a force range of 1-108 pN and a displacement range of 10-105 nm with a spatial resolution of the order of tens of nanometers are accessible with the instrument. The sample deformation (evolution) can be imaged simultaneously with rheological measurements. The device is used to perform extension rheology of polymer melts, silk, or other bio-fluids at microscales, measure mechanical responses of living cells such as neurons, muscle cells, etc. It is also used as a passive probe for microscale force measurements and to investigate properties of active suspensions such as bacterial baths.

In one embodiment, a method a method of displaying an image on a display device is described. The display device includes a plurality of clusters. Each cluster has a plurality of pixels and an independent light source associated therewith. Each of the plurality of clusters are illuminated with their associated independent light source. The plurality of pixels in a cluster are refreshed with bits of gray scale. Simultaneously with the refreshing, the light source associated with the cluster where the plurality of pixels are being refreshed is switched off. When the plurality of pixels have been refreshed, the light source is switched on with a predetermined intensity of light. Each of the clusters are refreshed at a rate that is fast enough to eliminate flicker.
