Surprisingly, most of existing provably secure FHE or SWHE schemes are lattice-based constructions. It is legitimate to question whether there is a mysterious link between homomorphic encryptions and lattices. This paper can be seen as a rst (partial) negative answer to this question. We propose a very simple private-key (partially) homomorphic encryption scheme whose security relies on factori...

The experimental data on muonic x-ray intensities for the third-row atoms (Z = 11-17) are analyzed in a unified way. The deduced initial/ distributions are not very far from the statistical ones; they are, however, somewhat steeper near the closed atomic shells and somewhat flatter in the middle of the shell. The K -electron refilling rate is fast increasing with Z; it is considerably smaller t...

Sweden has adopted a somewhat different approach to handle the corona pandemic, which been widely debated both on national and international levels. The Swedish model involves more individual responsibility reliance voluntary civic liability than law enforcement, while common measures in other countries are based controlling strategies, such as restrictive lockdowns, quarantines, closed borders...

abstract background: the loop colostomy is one of the most popular techniques used as a protective maneuver for a distal anastomosis and/or temporary fecal diversion. we are introducing the use of a full thickness skin bridge under the large bowel instead of a glass rod which alleviates problems such as protrusion of the large bowel, retraction of the bowel into the abdomen after removing the r...
