in this study, confined impinging liquid jets are used to produce nanoparticles of carbamazepine (cbz). the effect of operating parameters, such as the kind of solvent,cbz concentration, flow rate of solution and antisolvent on particle size, are experimentally investigated. the scanning electron micrograph (sem) photomicrographs show that nanodrug with smaller particle is achievable by using s...

Pilot contamination severely degrades the achievable rates in massive MIMO systems. To resolve the problem, many channel state information (CSI) and channel distribution information (CDI) methods were developed. This paper presents a CDI based pilot coordination method that leads to a considerable improvement in the achievable sum rate. It also shows that pilot assignment can drastically affect...

In this paper, we obtain a general achievable rate region and some certain capacity theorems for multiple-access relay channel (MARC), using decode and forward (DAF) strategy at the relay, superposition coding at the transmitters. Our general rate region (i) generalizes the achievability part of Slepian-Wolf multiple-access capacity theorem to the MARC, (ii) extends the Cover-El Gamal best achi...

In this letter, we investigate the uplink of a reconfigurable intelligent surface (RIS)-aided millimeter-wave (mmWave) multi-user system. considered system, however, problems with hardware cost and power consumption arise when massive antenna arrays coupled power-demanding analog-to-digital converters (ADCs) are employed. To account for practical complexity, consider that access point (AP) is e...

Generalized quadrature spatial modulation (GQSM) seamlessly amalgamates the generalized (GSM), (QSM) and vertical Bell Laboratories layered space-time (V-BLAST) techniques. In contrast to traditional multiple-input multiple-output (MIMO) schemes transmitting information bits only through constellation defined on complex plane, GQSM transmits additional implicitly by selecting transmit antenna (...

We study the communication of quantum information in networks of (directed) quantum channels. We consider the asymptotic rates of high fidelity quantum communication between specific sender-receiver pairs, and obtain outer and inner bounds of the achievable rate regions. All four scenarios of classical communication assistance (none, forward, backward, and two-way) are considered. For networks ...

For cooperative multicast systems using nonorthogonal multiple access, we propose optimal power allocation to maximize the achievable rate, and present its performance analysis in terms of average achievable rate and outage probability assuming Rayleigh fading channels. To perform the optimal power allocation, the source requires instantaneous channel information for a subset of the links. In t...

We study the asymptotically-achievable rate region of subspace codes for wireless network coding, where receivers have different link capacities due to the access ways or the faults of the intermediate links in the network. Firstly, an outer bound of the achievable rate region in a two-receiver network is derived from a combinatorial method. Subsequently, the achievability of the outer bound is...

The problem of separate zero-error coding of correlated sources is considered. Inner and outer single-letter bounds are established for the achievable rate region, and conditions for their coincidence are investigated. It is shown that successive encoding combined with time sharing is not always an optimal coding strategy. Conditions for its optimality are derived. The inner bound to the achiev...
