Heavy precipitation episodes and cosmic rays variation [PDF]

Advances in Geosciences, 2006
In this paper an attempt is made to investigate the possible temporal correlation between heavy precipitation episodes and cosmic rays' activity, on various time scales.

ACCELERATION OF COSMIC RAYS AT COSMIC SHOCKS [PDF]

Journal of The Korean Astronomical Society, 2003
Nonthermal particles can be produced due to incomplete thermalization at collisionless shocks and further accelerated to very high energies via diffusive shock acceleration. In a previous study we explored the cosmic ray (CR) acceleration at cosmic shocks through numerical simulations of CR modified, quasi-parallel shocks in 1D plane-parallel geometry ...

Swarm‐Optimized ZnO/CdS/CIGS/GaAs Solar Cell for Enhanced Efficiency and Thermal Resilience

Advanced Energy and Sustainability Research, EarlyView.
This article addresses the problem of optimizing the efficiency and thermal resilience of ZnO/CdS/CIGS solar cells, which are promising but still face challenges in maximizing performance under high‐temperature conditions and concentrated sunlight. The main issue is enhancing the efficiency of these cells while also ensuring that they can withstand the

Cosmic-Ray Bursts [PDF]

Physical Review, 1933
In cloud-chamber experiments the frequent occurrence of associated tracks has been observed.(1) It has been pointed out that a simple binary collision cannot explain all the associated tracks.(2)

The Physics of UHECRs: Spectra, Composition and the Transition Galactic-Extragalactic

, 2017
We review the experimental evidences about flux and mass composition of ultra high energy cosmic rays in connection with theoretical scenarios concerning astrophysical sources. In this context, we also address the discussion about the expected transition

Cosmic ray strangelets

Journal of Physics G: Nuclear and Particle Physics, 2005
Searching for strangelets in cosmic rays may be the best way to test the possible stability of strange quark matter. I review calculations of the astrophysical strangelet flux in the GV--TV rigidity range, which will be investigated from the Alpha Magnetic Spectrometer (AMS-02) on the International Space Station, and discuss the merits of strangelets ...

Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future

Advanced Intelligent Systems, EarlyView.
Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

GRBs on probation: testing the UHE CR paradigm with IceCube

, 2011
Gamma ray burst (GRB) fireballs provide one of very few astrophysical environments where one can contemplate the acceleration of cosmic rays to energies that exceed 10^20 eV.

Multi‐Century Grindstone Quarrying at Brumby Yard, Queensland

Archaeology in Oceania, EarlyView.
ABSTRACT The timing and duration of prehistoric quarrying is poorly understood within Australia, with limited ages available for quarries owing to the difficulties in dating these rock‐sediment constructions. We report the first multi‐sample, optically stimulated luminescence ages from quarry pits in Brumby Yard, an Aboriginal grindstone quarry ...
