Coded-cooperation combines virtual MIMO transmission and channel coding to achieve forward error correction while achieving diversity gain. It is a promising technology in 5G communications. The polar code the only that can theoretically Shannon limit transmission, which make it preferred cooperative communication. In this paper, we proposed new wireless communication scheme, coded spatial modu...

Single phonon excitations are sensitive probes of light-dark matter in the keV-GeV mass window. For anisotropic target materials, signal depends on direction incoming dark wind and exhibits a daily modulation. We discuss detail various sources anisotropy carry out comparative study 26 crystal targets, focused sub-MeV benchmarks. compute modulation reach for most promising corresponding to cross...

The acrosome reaction (AR) is influenced by the action of several molecules such as GABA, P 4 , and E 2 . Objective: to determine the interaction between GABA / E 2 , and GABA / P 4 in the AR. Methods: Washed human spermatozoa capacitated for 2 h were incubated in the following conditions: BWW medium alone (control) or BWW plus: P 4, E 2, GABA, GABA+ P 4 or GABA+ E 2. The % of AR was determined...

This paper presents a non-binary polar coding scheme that can reach the equidistant distant spectrum bound for discrete memoryless channels. This is the best that can be reached up to now and is tight for additive white Gaussian channels. To do this, we first define the equidistant property for the polarizing transforms. We have designed transforms that have better distance characteristics usin...

V697 Sco, the remnant of Nova Scorpii 1941 and currently at V ∼ 20.0, is found from photometric observations to have the characteristics of an intermediate polar (IP) with an orbital period (Porb) of 4.49 h and a rotation period (Prot) of 3.31 h. It therefore appears to be a member of the rare class of IPs where Prot ∼ Porb, which are probably discless systems. The prominence of the modulation ...

We investigate the spin rotational structure of magnetic skyrmions in a tetragonal polar magnet VOSe2O5 via polarized small-angle neutron scattering (SANS). Spin polarization analysis scattered neutrons provides consistent evidence for cycloidal modulation all incommensurate phases at zero and non-zero field along c axis, including triangular skyrmion-lattice phase. In vicinity skyrmion phase, ...

In many real world problems, data sometimes comes from n agents (n≥2), multipolar information exists. For issues that are associated with uncertainty, this information can not be showed with the values of crisp, fuzzy, intuitionistic or bipolar. Graph is one of the mathematical models widely used in different sciences. Ambiguity in a graph where data depends on the n parameter can not be showed...

We report the magnetocaloric effect of a bilayered perovskite ruthenate Ca3Ru2O7 that has recently been recognized as an antiferromagnetic polar metal. The magnetic entropy change obtained from temperature dependence DC magnetization measurements shows peaks and valleys under field near metamagnetic transitions, enable us to map out thermodynamic field–temperature phase-diagram. area surrounded...

There are various challenges in underwater acoustic communication (UWA) however bit error rate (BER) is considered as the main challenge it significantly affects UWA communication. In this paper, different coding schemes such convolution, turbo, low density parity check (LDPC), and polar based on t-distribution noise channel investigated, binary phase-shift keying (BPSK) modulation with a code ...
