ACCELERATION OF COSMIC RAYS AT COSMIC SHOCKS [PDF]
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
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

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

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
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
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
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 ...
