Theoretical Analysis of Two-Color Ghost Interference

Recently demonstrated ghost interference using correlated photons of different frequencies, has been theoretically analyzed. The calculation predicts an interesting nonlocal effect: the fringe width of the ghost interference depends not only on the wave-length of the photon involved, but also on the wavelength of the other photon with which it is entangled. This feature, arising because of different frequencies of the entangled photons, was hidden in the original ghost interference experiment. This prediction can be experimentally tested in a slightly modified version of the experiment.Comment: Published version. arXiv admin note: substantial text overlap with arXiv:quant-ph/050216

Ferit Orhan Pamuk: Novel, Theory and Practice

In literary world there are only few writers who are theorists and creative artists at the same time. But it is a general belief that every creative writer is a theorist whether or not he expresses it separately. Orhan Pamuk, the noble prize winner for literature, is one such writer who has separately delineated on the importance of theory in fiction. His all novels are actually expansion of this thoughts found in his seminal book about fiction titled The Naive and Sentimental Novelist. He believes that creation of imaginary world in fiction is ultimate task of a writer and for the necessary elements of that world he talks in detail in six lectures delivered by him and which ultimately got published in The Naive And Sentimental Novelist. The present work will look into detail about the theory and practice in Pamuk’s art

Television Dramas Standard in Pakistan

Pakistan television drama acknowledge by their innovation in past. When our drama telecast during golden age of PTV, roads would become empty. Time slot of 8:00 pm to 9:00 pm was prime time in every family. Things vicissitudes suddenly after influx of private channels and production of television dramas has negotiated the quality which was seen in dramas during the PTV era. After arrival of private TV drama channels needless serials on air on our TV screens. Nowadays if we calculate the dramas we all would soon over count the drams. But such extravagance of anything is bad in drama industry it came at price of declining standards of TV drama. The paper reviews how to bring quality back in Pakistani Dramas and what are the key factors to gain such popularity that PTV dramas used to have. This research paper is prepared on the basis of information and data acquired through meetings and interviews with several well known personalities of drama industry.</p

Effects of dietary exposure to Ochratoxin A (OTA) mycotoxin below/ around guidance values on embryo/fetal development and pregnancy success

Ochratoxin A (OTA) is a mycotoxin produced by some Aspergillus and Penicillium fungi and it induces several toxic effects. The present Ph.D. thesis investigated: 1) an in vitro pre-natal exposure model, by analyzing the effects of acute oocyte exposure to OTA on oocyte maturation and embryo development in the sheep; 2) an in vivo pre and post-natal exposure model, through examining OTA levels in feed, blood and milk samples of jennies and related foals. The sheep was used as a relevant model for human reproductive medicine. The donkey was used as suitable model to follow the route of natural exposure from feed to jennies during pregnancy and in foals after delivery. Moreover, donkey milk has high nutritional value in human diet. Ovine cumulus-oocyte complexes (COCs) were exposed to OTA during in vitro maturation (IVM) in a micro-to nanomolar range. After IVM, some oocytes were analyzed for Metaphase II (MII) rate, while others underwent in vitro fertilization (IVF) and embryo culture up to day7. Micromolar concentrations had adverse effects on cumulus expansion and viability, oocyte nuclear and cytoplasmic maturation and embryo development. At nanomolar concentrations, no adverse effects were found on COC viability and integrity whereas blastocyst had higher nuclear apoptosis. In donkey feed, toxin concentration was up to 2.7 ng/g with an incidence of 32%, far below the guidance values of OTA in feed materials reported by EU Recommendation 2016/1319. In jennies, the incidence of positive blood samples was 73% (median value= 114 ng/L; range 51 to 6000 ng/L). In foals, the incidence of positive blood samples was 50% (median value= 136 ng/L; range 79 to 4030 ng/L). No placental transfer of OTA was observed in all tested jennies and no influence on 2 pregnancy length and health of foals was observed. In milk, the incidence of positive samples was 36% (range 17 to 82 ng/L). In conclusion, in sheep, in vitro exposure to OTA affected oocyte function and embryo development; in jennies, no placental passage was observed but OTA passed from feed to milk through the blood. Effects on female fertility and newborn health need to be further investigated

Mitigating risks in managing cloud-based IT controls

Copyright © 2019 Inderscience Enterprises Ltd. Cloud computing (CC) represents a key tool in the race for innovation across industries. However, organisations are facing constraints in implementing and leveraging cloud technology for development purposes due to a lack of skills, knowledge and talent. To address this concern, this study focuses on the impact of CC on IT staff\u27s roles and responsibilities, within cloud user organisations. Accordingly, this study suggests skills required to mitigate the risks in the accountability and responsibility of managing IT controls. The results were empirically verified by senior IT practitioners. The empirical intervention emphasised on people\u27s business skills, in addition to domain knowledge and the mind-set to adapt to the changed environment. The findings of this study offers new insights for scholars and it will help IT decision makers to assess their staff\u27s capabilities to meet their business needs and to plan appropriate selection, training and hiring policies

Strengthening The Curriculum Of Information Systems Program

Information Systems as a field of academic study has witnessed tremendous growth in scope and depth since its beginning in the 1960s. Diversified information systems job market and widespread use of technology in healthcare organizations indicate a growing demand for IT personnel in healthcare organizations. This paper attempts to present a model for designing curriculum for Healthcare Information Systems concentration for an IT undergraduate program. The design of this curriculum is based on the recommendations of the Accreditation Board for Engineering &amp; Technology (ABET) - Computing Accreditation Commission (CAC). This model can be used by any higher educational institute that plans to redesign its IT curriculum to offer specializations. Lessons learnt indicate a need to get employers involved in the design process so that the knowledge and skill areas of the curriculum are responsive to the employer’s requirements

A Simulation-based Optimization Approach of the Public Transport Network for A Multiple-core City, Kabul

Kabul is the capital city of Afghanistan with the massive expansion of population since 2001. By 2025 Kabul’s population is projected to increase by 769; 539 inhabitants. This growth will not be only in the inner city, but with higher growth rate in the urban-cores, affecting the city structure morphologically as well as functionally. Before 2001, Kabul was a monocentric city with a dominant inner city; nowadays due to the rapid growth of population, Kabul is becoming morphologically polycentric city which needs transformation to a functionally polycentric shape. The fact that Kabul is becoming a polycentric city (with stronger urban - cores) makes it necessary to adapt its public transport network to this fact. Nowadays, around 58% of the trips between urban-cores are made by cars causing more congestion, emission, and high user cost. To overcome this problem, it is most likely to improve the public transport system capable of attracting more people to use it rather than cars. So, the idea attained here is to propose a new line linking the urban-cores to each other using the Headway-based Assignment procedure of the VISUM macro simulation software. This new line pretends to strengthen the urban-cores and create a more polycentric public transport network. Two alternatives will be studied as Alternative - 1 follows the present planning of the lines in city and urban-cores with buses that have a distance between stops of around 400 meters. The alternative - 2 shows planning for polycentrism, with the distance between stops around 800 meters and a speed higher than the alternative - 1. Furthermore, for each alternative different routes will be studied with respect to the base year 2016, and the target year 2025. Finally, all the alternatives and sub-alternatives will be compared among themselves and with the reference scenario to find the one which would improve the multi-core structure of Kabul effectively
