Analog network coding (ANC) as a simple implementation of physical layer network coding based on orthogonal frequency division multiplexing (OFDM) has been proposed to increase the network capacity and reliability of bi-directional link between a pair of users. In ANC protocol, an information between a pair of users is exchanged through two orthogonal time phases (i.e., multiple-access and broadcast phases). On the other hand, the phase noise (PN) introduces phase offset and inter carrier interference (ICI) to the useful signal. Thus, in ANC scheme PN will affect the useful signal during both multiple-access and broadcast phases. In this article, we present a performance analysis of ANC scheme using OFDM in the presence of PN in frequency-selective fading channel. We derive the total composite variance of ANC scheme in the presence of PN to obtain the signal-to-interference-plus-noise ratio (SINR) expression. Then, we evaluate the system's performance in terms of bit error rate (BER), SINR degradation, and ergodic capacity through both numerical and computer simulations. Computer simulated average BER has been consistent with the numerical results, validating the presented analysis. Our results have shown that the ANC scheme is more sensitive to the PN introduced during the broadcast phase (i.e., at destination) than during the multiple-access phase (i.e., at relay). This is because of the higher ICI to the useful signal and enhanced noise due to the imperfect self-information removal at the destination. In addition, the performance degradation of ANC scheme based on OFDM in the presence of PN is highly expressed for the PN linewidth values up to 20 Hz.

<p>A devastating earthquake (Mw 6.2) occurred on December 29, 2020,&#160; near the town of Petrinja, in Croatia, a few kilometers north of the Bosnian border with Croatia. The earthquake affected Bosnia and Herzegovina as well, and many buildings in northwestern Bosnia and Herzegovina were severely damaged. The main earthquake impact was preceded by two strong for-shocks, which shows a great resemblance to the Banja Luka earthquake of 1969. Seismic activity at the end of December 2020 and January 2021 was manifested through the occurrence of a large number of seismic events, namely: one earthquake of magnitude 6.2, two earthquakes of magnitude between 5.0 and 6.0, twenty-two earthquakes of magnitude between 4.0 and 5.0, sixty-six earthquakes of magnitude 3.0 and 4.0 and two hundred and seventy-seven earthquakes of magnitude between 2.0 and 3.0. This earthquake is a consequence of the movement of the Adriatic microplate and its interaction with the Eurasian tectonic plate. Its movement results in the creation of current seismicity in Croatia, Bosnia and Herzegovina, Italy, Montenegro, Serbia, Slovenia.</p><p>Today, analysis of the deformations of the Earth's crust plays an important role in research related to the entire seismic cycle. The phases of seismic cycles can be reliably estimated using time series of daily coordinates from continuously operating stations of the Global Navigation Satellite System (GNSS).</p><p>In this study, we used five time-series GNSS positions (Sarajevo, Pore&#269;, Ljubljana, Po&#382;ega, and Zadar), daily resolutions (24 hours) in the IGS14 reference frame, taken from Nevada Geodetic Laboratory through the website. We determined the coseismic displacement field of the Mw 6.2 Petrinja mainshock using downloaded the GNSS time-series as well as coseismic displacement field for all earthquakes of magnitude over 4. We processed data for the GNSS time series for the period from January 2016 to December 2020. GNSS stations are located at distances ~100 km to the ~250 km distances the epicenter of the Petrinja earthquake, of which the Pore&#269; station is the closest. JavaScript Object Notation (JSON) text format was used for processing all earthquakes in our study. JSON offset file is created based on the data downloaded from USGS (U.S. Geological Survey).</p><p>This paper, apply interactive processing in tectonics and seismology, presented offset in time series as a consequence of earthquakes. We have concluded that the cumulative movement of the Earth's crust is not only a consequence of large earthquakes but also the cause of many smaller accumulated movements caused by smaller earthquakes. The paper presents the contribution in the field of application of satellite positioning methods in geodynamic research and defines an approach that enables objective quantification of deformations of the Earth's crust in cases of seismic events. The earthquake occurred in a fault that extends approximately in the northwest-southeast direction and passes through Pokuplje near Petrinja and Glina. This fault is the boundary between two very different tectonic blocks, the Dinarides and the Pannonian Basin. Therefore, it can be said that the different stresses and displacements in these blocks are compensated through these blocks.</p>

We present a proof-of-concept study to assess whether deformable registration followed by tissue classification using machine learning (ML) is an effective method for the delineation of liver metastases in whole-body diffusion-weighted imaging (WB-DWI). Deformable atlas-based registration achieves good quality delineation of the liver (Dice coefficient > 70%) and out of three ML models random forest achieved the best F-1 measure for segmenting disease within the liver.
