Design of beamforming for IRS multi-partition-aided THz multi-subarray by Zufan ZHANG, Rui TANG

“…In the IRS-aided THz communication system, in order to break the channel sparsity limitation on the system spatial multiplexing gain, a hybrid beam forming architecture with wide-spaced multi-subarrays at the transceiver/transmitter side was proposed and the transmission scheme of IRS multi-partition-aided THz multi-subarrays was designed.Firstly, a non-convex objective function with multivariate coupling and non-convex constraints was constructed based on the principle of maximizing spectrum efficiency.Then, the optimization problem was decoupled into two easy-to-solve sub-problems, namely, the reflection coefficient matrix design of IRS and the hybrid beamforming matrix design at the transceiver/receiver.Finally, the Riemannian manifold optimization algorithm was used to calculate the reflection coefficient matrix of IRS, and the closed solution of the hybrid beamforming matrix design at the transceiver/receiver was obtained through mathematical derivation.Simulation results show that compared with the baseline scheme, the proposed scheme can achieve better spectrum efficiency.…”

An Improved Equation for Predicting Compressive Stress in Posttensioned Anchorage Zone by Young-Ha Park, Moon-Young Kim, Jong-Myen Park, Se-Jin Jeon

“…However, it was found that the formula can significantly overestimate the stresses in the actual prestressed concrete member with spaces occupied by ducts. Therefore, an improved equation was proposed for the existing AASHTO equation to consider the effect of the duct holes on the stress distribution. …”

Comparison of the efficiency of zero and first order minimization methods in neural networks by E. A. Gubareva, S. I. Khashin, E. S. Shemyakova

“…In particular, a new zero-order method for function minimization, descent over two-dimensional spaces, is proposed. The convergence rates of three different methods are compared: standard gradient descent with automatic step selection, coordinate descent with step selection for each coordinate, and descent over two-dimensional subspaces. …”

A low complexity pilot assignment algorithm based on user polar coordinates in CF-mMIMO systems by Shao GUO, Peng PAN, Yaozong FAN

“…Absrtact: In order to reduce the pilot contamination in the cell-free massive multi-input multi-output (MIMO) system, a low complexity pilot assignment algorithm based on user polar coordinates was proposed.Firstly, a Gaussian weighted density algorithm was proposed to determine a centroid as the polar coordinates center point in the system coverage area, then pre-assigned the pilot in order according to the angular coordinates, so that users who reused the same pilot had a greater probability of having a longer distance, and henced reduce the pilot contamination.A low complexity distance detection algorithm was then proposed to ensure that the user spacing between any two users multiplexing the same pilot was greater than the threshold.The simulation results show that the proposed pilot assignment algorithm effectively reduce pilot contamination, improve the uplink throughput of 95% users of the system, and achieve a good compromise between performance and complexity.…”

Secular Perturbations from Exterior Giants Strongly Influence Gap Complexity in Peas-in-a-pod Exoplanetary Systems by Joseph R. Livesey, Juliette Becker

“…It has been demonstrated that systems of tightly packed inner planets with giant exterior companions tend to have less regular orbital spacings than those without such companions. We investigate whether this observed increase in the gap complexity of the inner systems can be explained solely as the result of secular dynamics caused by the disturbing potential of the exterior companions. …”

Landscapes without landscape architects. The ecological beauty of informal urban landscapes by Chiara Catalano, Thomas E. Hauck, Susann Ahn, Salvatore Pasta

“…In the long term, the struggle between these two opposite ways of conceiving the look and the role of green infrastructure appears pointless: in the end, what decides the identity of most urban green infrastructure is the ‘vegetation by use’, that is, the daily people’s use of these spaces (whether accessible). By analysing the aesthetic value, the species composition, and the ecological meaning of the vegetation of some roadside habitats close to the city of Catania (Sicily), the Authors shed light on the possibility of enjoying low-cost, biodiverse and beautiful seasonally green areas.   …”
