<▼1><P>High quality graphene nanosheets produced in molten salts were found to be capable of wrapping silicon nanoparticles, leading to the fabrication of graphene encapsulated silicon nanoparticles with an excellent stable electrochemical performance as anode material for Li-ion batteries.</P></▼1><▼2><P>Graphite, which is commercially used as anode material in Li-ion batteries, has a low theoretical capacity of 372 mA h g<SUP>−1</SUP>, and therefore should be replaced by an alternative with high capacity and cyclability for the automotive and other applications. The new material should also be capable of being fabricated by energy efficient non-polluting methods at a reasonable cost. This paper reports on the fabrication of a graphene–silicon nanocomposite which meets all these characteristics. High quality graphene was scalably produced by exfoliation of graphite in molten lithium chloride. Graphene nanosheets produced were found to be capable of wrapping silicon nanoparticles injected into the molten salt, leading to the fabrication of graphene encapsulated silicon nanoparticles with a controllable chemical composition. The electrochemical performance of graphene encapsulated silicon nanoparticles was evaluated and compared with that of Si nanoparticles and mechanically blended Si/graphene. The graphene encapsulated silicon nanoparticles exhibited an excellent stable electrochemical lithiation/delithiation performance with the capacity value of about 2000 mA h per gram of silicon at a high current density of 0.5 A g<SUP>−1</SUP>. The nanocomposite sample containing 50 wt% Si showed a reversible capacity of 981 mA h g<SUP>−1</SUP> after 260 cycles. By increasing the amount of Si content of the nanocomposite to 91 wt%, the reversible stable capacity increased to 2217 mA h g<SUP>−1</SUP>, demonstrating the capability of the molten salt method to correlate the cost and electrochemical performance of the graphene–silicon nanocomposite product.</P></▼2>
A COMPARATIVE STUDY OF THE IRANIAN TOWERS OF THE SALJUQS AND THE CHINESE PAGODAS OF THE SONG DYNASTY
KAMALI, MARYAM Academia Via Serica 2016 Acta Via Serica Vol.1 No.1
This article compares two Iranian towers (burj) of the Saljuq period (c.1037-1194) with two Chinese Pagodas (t'a) of the Song dynasty (c.960-1279) in order to identify common cultural trends in medieval Iranian and Chinese architecture. To this end, the Iranian towers of Tuqrul in Rayy and Chihil Dukhtar in Damghan are compared with their Chinese counterparts of the Iron Pagoda in Kaifeng and the Pizhi Pagoda in Changqing. The two Iranian towers have much simpler architectural decorations compared to the splendid Song pagodas, which are decorated with statues and colorful paintings. The similarities in form, however, suggest common functions provided by the architecture. Both the Saljuq and Song towers had astronomical and military functions, position identification for travelers, and symbolic meanings, as well as their main functions as tombs. By applying comparative studies on the forms and functions of the Tuqrul and Chihil Dukhtar towers on the one hand, and the Iron and Pizhi Pagodas, on the other hand, this article aims to contribute new insights regarding common social trends shared by the medieval Iranian and Chinese and illustrated by their architecture. Extensive and distinguished publications on the general subject of art and architecture during the reign of the two dynasties under discussion already exist, as fully referenced below, but the specific comparative themes regarding the individual sites discussed here are the first in any study of this kind.
Drug- and Gene-eluting Stents for Preventing Coronary Restenosis
Kamali Manickavasagam Lekshmi,Hui-Lian Che,조정수,박인규 전남대학교 의과학연구소 2017 전남의대학술지 Vol.53 No.1
Coronary artery disease (CAD) has been reported to be a major cause of death worldwide. Current treatment methods include atherectomy, coronary angioplasty (as a percutaneous coronary intervention), and coronary artery bypass. Among them, the insertion of stents into the coronary artery is one of the commonly used methods for CAD, although the formation of in-stent restenosis (ISR) is a major drawback, demanding improvement in stent technology. Stents can be improved using the delivery of DNA, siRNA, and miRNA rather than anti-inflammatory/anti-thrombotic drugs. In particular, genes that could interfere with the development of plaque around infected regions are conjugated on the stent surface to inhibit neointimal formation. Despite their potential benefits, it is necessary to explore the various properties of gene-eluting stents. Furthermore, multifunctional electronic stents that can be used as a biosensor and deliver drug- or gene-based on physiological condition will be a very promising way to the successful treatment of ISR. In this review, we have discussed the molecular mechanism of restenosis, the use of drug- and gene-eluting stents, and the possible roles that these stents have in the prevention and treatment of coronary restenosis. Further, we have explained how multifunctional electronic stents could be used as a biosensor and deliver drugs based on physiological conditions
ON A SUBCLASS OF CERTAIN STARLIKE FUNCTIONS WITH NEGATIVE COEFFICIENTS
Kamali, Muhammet,Orhan, Halit Korean Mathematical Society 2004 대한수학회보 Vol.41 No.1
A certain subclass $T_{\Omega}(n,\;p,\;\lambda,\;\alpha)$ of starlike functions in the unit disk is introduced. The object of the present paper is to derive several interesting properties of functions belonging to the class $T_{\Omega}(n,\;p,\;\lambda,\;\alpha)$. Coefficient inequalities, distortion theorems and closure theorems of functions belonging to the class $T_{\Omega}(n,\;p,\;\lambda,\;\alpha)$ are determined. Also we obtain radii of convexity for the class $T_{\Omega}(n,\;p,\;\lambda,\;\alpha)$. Furthermore, integral operators and modified Hadamard products of several functions belonging to the class $T_{\Omega}(n,\;p,\;\lambda,\;\alpha)$ are studied here.

Transcutaneous electrical nerve stimulation (TENS) is awidely-practiced method to increase blood flow in clinical practice. The best location for stimulation to achieve optimal blood flow has not yet been determined. We compared the effect of TENS application at sympathetic ganglions and acupuncture points on blood flow in the foot of healthy individuals. Seventy-five healthy individuals were randomly assigned to three groups. The first group received cutaneous electrical stimulation at the thoracolumbar sympathetic ganglions. Thesecond group received stimulation at acupuncture points. Thethird group received stimulation in the mid-calf area as a control group. Blood flowwas recorded at time zero as baseline and every 3 minutes after baseline during stimulation, with a laser Doppler flow-meter. Individuals who received sympathetic ganglion stimulation showed significantly greater blood flow than those receiving acupuncture point stimulation or those in the control group (p < 0.001). Data analysis revealed that blood flow at different times during stimulation increased significantly from time zero in each group. Therefore, the application of lowfrequency TENS at the thoracolumbar sympathetic ganglions was more effective in increasing peripheral blood circulation than stimulation at acupuncture points.

This paper introduces a new nozzle-flapper valve with isothermal chamber using piezoelectric actuator. It controls the pressure and flow rate simply, effectively and separately. The proposed valve uses isothermal chamber presenting practical isothermal condition due to its large heat transfer interfaces filled by metal wool. The valve uses stacked type piezoelectric actuator with unique advantages. By using this valve, a simple method has been fulfilled to control flow rate or pressure of ideal gases in a pneumatic actuators. Experimental results demonstrated applications of the proposed valve to control either pressure or flow rate in pneumatic circuits. This valve can be also used in the pilot stage valve to actuate the main stage of a much bigger pneumatic valve. Designated structure contains only one pressure sensor installed on the isothermal control chamber, capable of controlling both pressure and flow rate. The desired output mass flow rate of the valve is controlled by the pressure changes during positioning of piezoelectric actuator at proper position. The proposed valve can control steady and unsteady oscillatory flow rate and pressure effectively, using nonlinear control method such as feedback linearization approach. Its effectiveness is demonstrated and validated through simulation and experiments.
Generative Adversarial Network with Face Alignment for Face Generation
Adib Kamali,Udurume Miracle,Udeogu Chigozie Uzochukwu,Angela Caliwag,Wansu Lim 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.11
Face generation is extensively conducted to increase the number of face images dataset. In face generation field, Generative Adversarial Network (GAN) have shown remarkable success in face image generations. However, most of the existing methods only generate face images from random noise, and cannot generate faces according to face alignment. This make GAN produce poor quality face images when using unaligned face image. In this paper, we propose face generation based on GAN with considering the face alignments. In detail, original face images which is not always aligned is fed to the face alignment module. Then the aligned face images is added noises. The aligned images with noise are then used as input for GAN based image generator. Generator and discriminator are trained to optimize the face generation model performance. Based on extensive experimental study, we present the analysis on face alignment and face generation result with and without considering face alignment.
