Multiple point compression on curves
Multiple point compression is an important feature to improve the implementation of
elliptic curve cryptography. This can be extended to other curves, in particular hyperelliptic curves, with
divisors represented in Mumford form
STRUCTURE FORMATION PROCESS OF HYDRATED PORTLAND CEMENT COMPOSITIONS: NANOSCALE LEVEL CONTROL
Durability of cement-like construction materials, as well as durability of cement stone, depends on their humidity resistance, frost resistance, corrosion resistance. All of these properties depend not only on the composition of the original clinker, but also on structural organization at micro-and nanoscale level of hydrated portland cement compositions. In this research the authors used the method of small-angle neutron scattering to define structural parameters of hydrated portland cement compositions on nanoscale level, distribution of calcium hydrate silicate nanoparticles in size, medium nanoparticles radius, fractal dimension. It is shown, that introduction of modifying nanoadditives into portland cement compositions affects structural parameters of a cement stone. The following nanoadditives were used: of artificial (alpha aluminium oxide, gamma aluminum oxide) and of anthropogenic (carbonate and alumo-alkaline sludges) origin, as well as integrated nanoadditives containing surfactants. The change in structural parameters of portland cement compositions with nanoadditives in the process of hydration is investigated. It is shown that use of nanoadditives allows to control the process of forming the structure of hydrated portland cement composition on the nanoscale level, directly affect the values of structural parameters and, as a result, modify properties of cement stone

Concrete ways of activization of educational process require deep study; the didactic potential of these technologies still is not described in a due measure. The electronic synopsis of lecture for the teacher combines technical opportunities of computer and video equipment in representation of a teaching material with live dialogue of the lecturer with an audience. Actually it is a new main educational process control tool for an audience with enough greater number of students. The electronic synopsis for the student should represent an additional supply with information to training course lectures. It may consist of schemes, schedules, interactive animations, and other materials required for discipline study. Presence of these materials in the electronic abstract allows us to save lecture time and pay more attention to complicated questions since students get acquainted with all it under orders of the teacher before the lesson,. Thus, the electronic abstract is intended for the organization of independent work of students during the study of theoretical positions of studied discipline. In view of the tendency to reduction of lessons volume, development and introduction of electronic synopsizes for students together with further development of all electronic SMC appears to be duly and very actual

Memory Effect and Triplet Pairing Generation in the Superconducting Exchange Biased Co/CoOx/Cu41Ni59/Nb/Cu41Ni59 Layered Heterostructure
We fabricated a nanolayered hybrid superconductor-ferromagnet spin-valve
structure, the resistive state of which depends on the preceding magnetic field
polarity. The effect is based on a strong exchange bias (about -2 kOe) on a
diluted ferromagnetic copper-nickel alloy and generation of a long range odd in
frequency triplet pairing component. The difference of high and low resistance
states at zero magnetic field is 90% of the normal state resistance for a
transport current of 250 {\mu}A and still around 42% for 10 {\mu}A. Both logic
states of the structure do not require biasing fields or currents in the idle
mode.Comment: 9 pages, 4 figures, Accepted to Applied Physics Letter
