Abstract NEWAGE is a direction-sensitive dark matter search using low-pressure gaseous time projection chamber. A low alpha-ray emission rate micro pixel chamber had been developed in order to reduce background for search. We conducted the at Kamioka Observatory 2018. The total live was 107.6 d, corresponding an exposure of 1.1 kg$\>$d. Two events remained energy region 50–60 keV, which ...

Three cyphers allegedly authored by Thomas Jefferson Beale in 1822 have been the subject of intensive study for over one hundred years. Generations of cryptanalysts have expended untold man-years, thus far without success, attempting to decode them; vast armies of fortune hunters and treasure seekers have devoted Herculean labors to digging up the rolling hills of Virginia trying to locate the ...

In this paper we propose three iterative greedy algorithms for compressed sensing, called iterative alternating direction (IAD), normalized iterative alternating direction (NIAD) and alternating direction pursuit (ADP), which stem from the iteration steps of alternating direction method of multiplier (ADMM) for `0-regularized least squares (`0-LS) and can be considered as the alternating direct...

In this paper we introduce two normalized versions of non-perfect security for private-key encryption: one version in the framework of Shannon entropy, another version in the framework of Kolmogorov complexity. We prove the lower bound on either key entropy or key size for these models and study the relations between these normalized security notions.

BACKGROUND The exponential increase in health-related online platforms has made the Internet one of the main sources of health information globally. The quality of health contents disseminated on the Internet has been a central focus for many researchers. To date, however, few comparative content analyses of pro- and anti-vaccination websites have been conducted, and none of them compared the q...

OBJECTIVE The purpose of this study is to investigate the physiological pulmonary perfusion pattern in different respiratory phases by calculating the normalized volume center of perfusion intensity. METHODS Four nonsmoking volunteers underwent single photon emission computed tomography (SPECT) of maximum inspiration and expiration after the injection of Tc-99m-MAA in each respiratory phase a...
