Cryptosporidium parvum and Giardia lamblia are two of the most chlorine resistant microorganisms with notable adverse effects on humans. Our study shows that waters containing these two protozoa at low concentrations can be efficiently disinfected in continuous flow by using a commercial fibrous ceramic TiO(2) photocatalyst. The efficiency of the photocatalytic disinfection is largely enhanced ...

The detectability of planetesimal impacts on imaged exoplanets can be measured using Jupiter during the 1994 comet Shoemaker-Levy 9 events as a proxy. By integrating the whole planet flux with and without impact spots, the effect of the impacts at wavelengths from 2 4 μm is revealed. Jupiter’s reflected light spectrum in the near-infrared is dominated by its methane opacity including a deep ban...

In this paper, a new algorithm to solve the discrete logarithm problem is presented which is similar to the usual baby-step giant-step algorithm. Our algorithm exploits the order of the discrete logarithm in the multiplicative group of a finite field. Using randomization with parallelized collision search, our algorithm indicates some weakness in NIST curves over prime fields which are consider...

We study the giant magnon solutions in the near horizon geometry of the Neveu-Schwarz (NS) 5-brane background. In conformal gauge, we find magnon dispersion relation in the large angular momentum (J) limit. We further show that the giant magnon poses uniform distribution of the angular momentum along the string world-sheet as in case of AdS5 × S5 spacetime.

Despite common belief, Baby Boomers form a sizable population of gamers. Paying attention to how this generation experiences a game can help companies that target this group of users increase their market share. To address this need, this study examines Baby Boomers’ reaction to a new way of manipulating objects in a game, namely with their eyes. In particular, the study focuses on testing the ...

CO2 is among the most stable molecules, requiring high amounts of energy to be activated. Photosynthesis allows the conversion of CO2 and H2O, the major products of combustion, into useful organic compounds and represents one of the most efficient ways for CO2 capture, besides its absorption in oceanic water. This is a natural but complex process leading to a regenerated fuel by photo-irradiati...

We analyze the energy and angular momenta of the two-spin spiky string moving on the AdS3×S with NS-NS field. Due to the infinite boundary of the AdS spacetime the solution will extend to infinity and it appears the divergences. After adding the counter terms we then obtain the dispersion relation of the corresponding giant magnon and see how the background field produces the correction terms. ...

In [BKT11] Baba, Kotyada and Teja introduced the FACTOR problem over non-abelian groups as base of an ElGamal-like cryptosystem. They conjectured that there is no better method than the naive one to solve the FACTOR problem in a general group. Shortly afterwards Stanek published an extension of the baby-step giant-step algorithm disproving this conjecture [Sta11]. Since baby-step giant-step met...
