We introduce Twin RSA, pairs of RSA moduli (n, n + 2), and formulate several questions related to it. Our main questions are: is Twin RSA secure, and what is it good for?

limb bud first appears during the third week of gestation with the upper limb buds appearing a few days before the lower limb buds. complete absence of one or more limbs, called amelia, occurs prior to the eighth week of gestation. we report a case of amelia in a twin gestation.

in this paper, we investigate various kinds of extensions of twin-good rings. moreover, we prove that every element of an abelian neat ring r is twin-good if and only if r has no factor ring isomorphic to z2  or z3. the main result of [24] states some conditions that any right self-injective ring r is twin-good. we extend this result to any regular baer ring r by proving that every element of a...

Hydrothermal carbonization process can transform wet bio-wastes into value-added products. This work aims to hybridize a concentrating solar technology and biomass reactor for the continuous sustainable valorization of biomass. The novel proposed integrates linear beam-down field with twin-screw HTC process. consists two reflections that concentrate linearly sun energy on ground, where is place...

This paper presents a mobile Lidar system for efficiently and accurately capturing the 3D shape of the Bas-reliefs in Angkor Wat. The sensor system consists of two main components: 1) a panoramic camera and 2) a 2D 360-degree laser line scanner, which moves slowly on the rails parallel to the reliefs. In this paper, we first propose a new but simple method to accurately calibrate the panoramic ...

in this work, ternary polymer blends based on polypropylene (pp)/ polyethylene terephthalate (pet) /poly(styrene-b (ethylene-co-butylene)-b-styrene) (sebs) triblock copolymer and a reactive maleic anhydride grafted sebs (sebs-g-mah) at various compositions were prepared by co-rotating twin screw extruder. the effects of pet, sebs and sebs-g-mah compatibilizer on morphology of the blends were ex...
