Design of evolutionary computational intelligent solver for nonlinear corneal shape model by Mexican Hat and Gaussian wavelet neural networks
No full textIn this study, an integrated computational intelligence algorithm is implemented for the numerical treatment of the two-point boundary value problems that arise in the nonlinear corneal shape (NCS) model through the exploitation of wavelet neural networks including Mexican-Hat (MHWNNs) and Gaussian-wavelet (GWNNs)
through global genetic algorithms (GAs) then hybridization with local sequential quadratic programming (SQP) solvers, i.e. MHWNNsGAs, GWNNs-GAs, MHWNNs-GA-SQP, and GWNNs-GA-SQP respectively. The GWNNs and MHWNNs are applied to calculate the mean squared error of mathematical modeling of the proposed problem through objective functions while optimization of the fitness functions is initially conducted with an efficiency of global search GAs and then the efficacy of local search technique SQP for fine-tuning. A comparison of the proposed solutions of MHWNNs-GAs, GWNNsGAs, MHWNNs-GA-SQP, and GWNNs-GA-SQP solvers with a reference solution of Adam’s method shows that the proposed schemes have better accuracy, stability, efficiency consistency on an independent number of runs analyzed through complexity analysis and different statistical operators

Design of stochastic computational Levenberg Marquardt backpropagation-based technique to investigate temperature distribution of longitudinal moving porous fin
No full textAbstract The improvement of thermal exchange is of utmost interest in a wide range of engineering areas. The current study focuses on thermal evaluation involving natural radiation and convection in a fractionally arranged moving longitudinal fin model placed under a magnetic field. We implement the Levenberg Marquardt backpropagation (LMB) algorithm for investigating an innovative use of stochastic numerical computation for analyzing the efficiency of the temperature distribution in a porous moving longitudinal fin. The datasets for LMB have been created using a shooting approach for dynamic systems with varying ranges of different parameters. The validation, testing, and training processes are used to simulate networks using the LMB approach for diverse scenarios of moving porous fin models. The reliability of results is assessed based on the regression measures, absolute error, error histograms, mean square error, and other metrics for fuller numerical modeling of the suggested LMB to investigate the thermal efficiency and effectiveness of porous moving fin
Risk factors associated with ectopic pregnancy: A case control study.
No full textIntroduction: Ectopic pregnancy (EP) accounting for 10% of all pregnancies is a major health problem for women of childbearing age and leading cause of maternal deaths. The identified risk factors are previous ectopic pregnancy, previous pelvic surgery, induction of ovulation, intrauterine device usage, history of pelvic inflammatory disease, and smoking at the time of conception.
Objective: To identify risk factor for ectopic pregnancy so that appropriate directional strategies may be developed to reduce its prevalence.
Methodology: This observational case control study was conducted with sample size of 100 (50 cases, 50 control) from January 2017 to 30 July 2017 at different hospitals of Sindh and Punjab. For this study, case was defined as a pregnant woman with a confirmed tubal ectopic gestation, while control as pregnant women with a confirmed normal intrauterine pregnancy. Information regarding demographic socio-economic status and risk factors were also collected.
Results: The case & control groups were almost similar with respect to age, education, residence, age of marriage and parity. There was a significant association between prior ectopic pregnancy (OR 15.47, CI 95% 1.92-124.3, p=0.00) , history of previous pelvic inflammatory diseases (PID) (OR 13.5, CI 95% 5.09-35.83, p=0.01), smoking (OR 15.47, CI 95% 1.92-124.3, p=0.00), history of endometriosis (OR 4.04, CI95%1.22-13.47, p=0.00), use of intrauterine contraceptive device (IUCD) (OR 5.41, CI 95% 1.66-17.65, p=0.00), and previous cesarean section(OR 2.42,CI 95%1.04-5.63, p=0.02).
Conclusion: Identification of risk factors for ectopic pregnancy may help in early detection and appropriate management. Risk factors modification, such as cigarette smoking, use of IUCD and first pregnancy interval may be effective as risk-reduction strategies.

Reduction of Substrate Noise in Sub Clock Frequency Range
No full textWe propose a method of reducing the switching noise in the substrate of an integrated circuit. The main idea is to design the digital circuits to obtain a periodic supply current with the same period as the clock. This property locates the frequency components of the switching noise above the clock frequency. Differential return-to-zero signaling is used to reduce the data-dependency of the current. Circuits are implemented in symmetrical precharged DCVS logic with internally asynchronous D registers. A chip was fabricated in a standard 130-nm CMOS technology holding two versions of a pipelined 16-bit adder. First version employed the proposed method, and second version used conventional static CMOS logic circuits and TSPC registers. The respective device counts are 1190 and 684, and maximal operating frequencies 450 and 375 MHz. Frequency domain measurements were performed at the substrate node with on-chip generated sinusoidal and pseudo-random data at a clock frequency of 300 MHz. The sinusoidal case resulted in the largest frequency components, where an 8.5 dB/Hz decrease in maximal power is measured for the proposed circuitry at a cost of three times larger power consumption.©2009 IEEE.

Intracellular K(+) Determination With a Potentiometric Microelectrode Based on ZnO Nanowires
No full textThe fabrication and application of an intracellular K(+)-selective microelectrode is demonstrated. ZnO nanowires with a diameter of 100-180 nm and a length of approximately 1.5. m are grown on a borosilicate glass microcapillary. The ZnO nanowires were coated by a K(+)-ionophore-containing membrane. The K(+)-selective microelectrode exhibited a K(+)-dependent potentiometric response versus an Ag/AgCl reference microelectrode that was linear over a large concentration range (25 . M-125 mM) with a minimum detection limit of 1 . M. The measured K(+) concentrations in human adipocytes and in frog oocytes were consistent with values of K(+) concentrations reported in the literature. The sensor has several advantages including ease of fabrication, ease of insertion into the cells, low cost, and high selectivity features that make this type of sensor suitable to characterize physiologically relevant ions within single living cells.©2011 IEEE.

No full textTranslation has become as one of the most important and fundamental needs of modern era. Translation is the art which not only helps us to get an opportunity of benefiting from the academic and literary treasure of other countries but opens an avenue of unlimited growth for one language as well. Humanity has utilized the art of translation in order to meet its religious, social and financial needs in each and every era.The scope of Urdu language is enriched with different translations which certainly begins with the translations of Holy Quran. After that the process kept on enriching other fields of knowledge and literature. During the course of translation master pieces of prose and poetry of other languages were transformed into Urdu. Ali Garh College, Dehli College and Dar-ul-Tarjuma Usmania contributed well in this regard. "Makhzan" has also played vital role as far as the poetical translations are concerned. The poetical Urdu translations are indebted and obliged by the great work of Allama Muhammad Iqbal, Muhammad Hussain Azad, Ameer Chand Bahar, Syed Shakir Ali and Syed Ali Hasnain Naqvi. This tradition of poetical Urdu translations from classical and modern western poetry collection is still flourishing and progressing with full pace and in desired direction. This tradition/process is helping the quantity of Urdu poetry and more importantly this art is heading towards the desired destination of maturity and growth.

<Special Feature "Publication and Distribution of Islamic Books in South Asia 2">Annotation of Books on Saiyid Ahmad Khān and the Aligarh Movement in the Aqeel Collection
No full textSir Syed Ahmad Khan (Sar Saiyid Aḥmad Khān, 1817–98) is known as the leader of the social and political reform movement called the “Aligarh Movement”, a modernization drive by Muslims in India, as well as the founder of the modernized educational institution, namely, Aligarh University. For the modernization of Indian Muslims, Ahmad Khan wrote many articles and essays in his own magazines, and the followers of Ahmad Khan also wrote many books and articles for the same purpose. The Aqeel Collection of Kyoto University has more than 200 books and magazines about Ahmad Khan and the Aligarh Movement. Among these books, there are some rare books and magazines that were published in the late nineteenth century and the beginning of the twentieth century, that is to say, in the contemporary period of Ahmad Khan himself. Although the founder of the Aqeel Collection, Dr. Moinuddin Aqeel (Mu‘īn al-Dīn ‘Aqīl), migrated to Pakistan during his childhood and grew up in the city of Karachi, the Aqeel Collection has quite a number of books and magazines that were published in India, especially in Aligarh, the center of the Aligarh Movement. That is why these books and magazines can cover most of the demands of research on Ahmad Khan and his movement. Since most of Ahmad Khan’s works were published from Pakistan’s state-financed institution for the promotion of Urdu literature, Majlis Taraqqī Adab, Lahore in 1970s, this annotation tries to introduce some other important books that must be essential for the study of this field and through the study of Ahmad Khan and his period we can recognize the whole perspective of the modernization movement in the Muslim society in South Asia from the late nineteenth to the early twentieth centuries
