COEFFICIENT ESTIMATES FOR CERTAIN SUBCLASS OF MEROMORPHIC AND BI-UNIVALENT FUNCTIONS
Salehian, Safa,Zireh, Ahmad Korean Mathematical Society 2017 대한수학회논문집 Vol.32 No.2
In this paper, we introduce and investigate an interesting subclass of meromorphic bi-univalent functions defined on ${\Delta}=\{z{\in}{\mathbb{C}}$ : 1 < |z| < ${\infty}\}$. For functions belonging to this class, estimates on the initial coefficients are obtained. The results presented in this paper would generalize and improve some recent works of several earlier authors.
NEW SUBCLASS OF BI-UNIVALENT FUNCTIONS BY (p, q)-DERIVATIVE OPERATOR
Motamednezhad, Ahmad,Salehian, Safa The Honam Mathematical Society 2019 호남수학학술지 Vol.41 No.2
In this paper, we introduce interesting subclasses ${\mathcal{H}}^{p,q,{\beta},{\alpha}}_{{\sigma}B}$ and ${\mathcal{H}}^{p,q,{\beta}}_{{\sigma}B}({\gamma})$ of bi-univalent functions by (p, q)-derivative operator. Furthermore, we find upper bounds for the second and third coefficients for functions in these subclasses. The results presented in this paper would generalize and improve some recent works of several earlier authors.

Ectopic varices (EcV) are enlarged portosystemic venous collaterals, which usually develop secondary to portal hypertension (PHT). Mesocaval collateral vessels are unusual pathways to decompress the portal system. Here we report the case of a huge varicose inferior mesenteric vein (IMV) that drained into perirectal collateral veins, demonstrated by $^{99m}Tc$-labeled red blood cell (RBC) scintigraphy performed for lower gastrointestinal (GI) bleeding in a 14-year-old girl. This case illustrates the crucial role of $^{99m}Tc$-labeled RBC scintigraphy for the diagnosis of rare ectopic lower GI varices.

$TiO_2$ nanoparticles were synthesized and characterized by SEM and XRD techniques. The $TiO_2$ nanoparticles were employed as a recyclable, inexpensive and efficient catalyst for the synthesis of substituted quinoxalines in high to excellent yields and in relatively short duration.
New subclass of bi-univalent functions by $(p,q)$-derivative operator
Ahmad Motamednezhad,Safa Salehian 호남수학회 2019 호남수학학술지 Vol.41 No.2
In this paper, we introduce interesting subclasses $ {\mathcal H}_{{\sigma}_{\mathfrak B}}^{p,q,\beta,\alpha}$ and $ {\mathcal H}_{{\sigma}_{\mathfrak B}}^{p,q,\beta}(\gamma)$ of bi-univalent functions by $(p,q)$-derivative operator. Furthermore, we find upper bounds for the second and third coefficients for functions in these subclasses.

Layered-Division Multiplexing: An Enabling Technology for Multicast/Broadcast Service Delivery in 5G
Zhang, Liang,Wu, Yiyan,Li, Wei,Salehian, Khalil,Lafleche, Sebastien,Wang, Xianbin,Park, Sung Ik,Kim, Heung Mook,Lee, Jae-young,Hur, Namho,Angueira, Pablo,Montalban, Jon Institute of Electrical and Electronics Engineers 2018 IEEE communications magazine Vol.56 No.3
<P>Future 5G systems will include a point-to-multipoint (P2MP) transmission mode to achieve high capacity and high spectrum efficiency for multiple use cases, such as IoT, lifeline communications, and broadcast-type services. Layered-division-multiplexing (LDM) is a novel non-orthogonal multiplexing technology recently adopted by the next generation digital TV broadcast system, ATSC 3.0, which is capable of providing significant capacity improvement when delivering multiple broadcast services simultaneously. This article explores the application of LDM as an enabling technology for 5G to achieve high-efficiency P2MP transmission and to deliver more diversified broadcast-type services using the mobile broadband infrastructure. The potential advantages that can be offered by LDM are demonstrated by capacity analysis and computer simulations. Coverage studies show that a 5G P2MP subsystem with LDM can deliver high-quality broadcast services using the broadband infrastructure. Finally, some general guidelines on the receiver implementation are presented to minimize the hardware complexity of consumer devices.</P>
Sensitivity analysis of the plastic hinge region in the wall pier of reinforced concrete bridges
Ali Babaei,Alireza Mortezaei,Hamid Salehian 국제구조공학회 2019 Structural Engineering and Mechanics, An Int'l Jou Vol.72 No.6
As the bridges are an integral part of the transportation network, their function as one of the most important vital arteries during an earthquake is fundamental. In a design point of view, the bridges piers, and in particular the wall piers, are considered as effective structural elements in the seismic response of bridge structures due to their cantilever performance. Owing to reduced seismic load during design procedure, the response of these structural components should be ductile. This ductile behavior has a direct and decisive correlation to the development of plastic hinge region at the base of the wall pier. Several international seismic design codes and guidelines have suggested special detailing to assure ductile response in this region. In this paper, the parameters which affect the length of plastic hinge region in the reinforced concrete bridge with wall piers were examined and the sensitivity of these parameters was evaluated on the length of the plastic hinge region. Sensitivity analysis was accomplished by independently variable parameters with one standard deviation away from their means. For this aim, the Monte Carlo simulation, tornado diagram analysis, and first order second moment method were used to determine the uncertainties associated with analysis parameters. The results showed that, among the considered design variables, the aspect ratio of the pier wall (length to width ratio) and axial load level were the most important design parameters in the plastic hinge region, while the yield strength of transverse reinforcements had the least effect on determining the length of this region.

<P>LDM, a non-orthogonal multiplexing technology, is one of the main innovations in ATSC 3.0, a next generation terrestrial TV broadcast system. This article gives a general overview of the LDM technology, its current applications in the ATSC 3.0 system, and its cost in terms of the required additional complexity. The transmission capacity benefit offered by LDM is explained by theoretical analysis and demonstrated by simulation results. An efficient implementation scheme is described with less than 15 percent complexity increase. New service coverage paradigms enabled by LDM are presented. Finally, more future innovative applications of LDM, along with their benefits and challenges, are introduced. These include using LDM for wireless in-band backhaul, combining LDM with scalable video coding, and the application of LDM in other future broadcasting and 4G/5G broadband systems.</P>
