The Abasyn University is a private research university located in the residential neighborhood of Peshawar, Khyber-Pakhtunkhwa, Pakistan. The university also has a teaching campus in Islamabad; however, its main campus is in Peshawar.Founded with the efforts led by the provincial government of Khyber-Pakhtunkhwa in 2007, the university is a private-sector institution of higher learning. The university offers undergraduate and post-graduate studies; it's noted for its engaging research in the development of augmented reality and artificial intelligence. Wikipedia.

Frequent itemsets (FIs) mining is a prime research area in association rule mining. The customary techniques find FIs or its variants on the basis of either support threshold value or by setting two generic parameters, i.e., N (topmost itemsets) and (Formula presented.) (size of the itemsets). However, users are unable to mine the absolute desired number of patterns because they tune these approaches with their approximate parameters settings. We proposed a novel technique, top-K Miner that does not require setting of support threshold, N and (Formula presented.) values. Top-K Miner requires the user to specify only a single parameter, i.e., K to find the desired number of frequent patterns called identical frequent itemsets (IFIs). Top-K Miner uses a novel candidate production algorithm called join-FI algorithm. This algorithm uses frequent 2-itemsets to yield one or more candidate itemsets of arbitrary size. The join-FI algorithm follows bottom-up recursive technique to construct candidate-itemsets-search tree. Finally, the generated candidate itemsets are manipulated by the Maintain-Top-K_List algorithm to produce Top-K_List of the IFIs. The proposed top-K Miner algorithm significantly outperforms the generic benchmark techniques even when they are running with the ideal parameters settings. © 2015 Springer-Verlag London Source

Brain drain is the flow of skilled and qualified man power from a home country to host country leaving the former, socio-economically underdeveloped. The role of Pakistani medical diaspora in improving the health care system and socio-economic development of the country through brain circulation is discussed in this paper. Different secondary sources such as published research studies, government reports, newspapers and published interviews were consulted to gather information. The data collected was analyzed by using documentary and content analysis. Diaspora option can be used as a strategy to reverse and prevent the harmful effects of medical brain drain through brain gain and brain circulation. The government can play its vital role to facilitate the diaspora network between home and host countries. Diaspora networks should be mobilized to transfer knowledge, skills and ideas to their home country. However, diaspora networks are successful when home country is equipped with infrastructure, and with economic and political stability and strategic policies. © 2016, Journal of Postgraduate Medical Institute.

A digraph G = (V,E) is upward planar if it has a planar drawing with all edges pointing upward. A subgraph G̃ of a digraph G with an upward planar drawing is called a maximal upward planar subgraph of G if the addition of any edge in G/G̃ to G̃ causes non-upward planarity. Binucci et al. showed that finding even the maximum upward planar subgraph of an embedded digraph Gφ is NP-Complete [1]. In this paper, we compare different algorithms to find maximal upward planar subgraph of an embedded digraph. We also use a large test suite of embedded digraphs to gain a deeper understanding of upward planarity and see how the different heuristics perform in practice. © 2012 IEEE. Source

Background: The current work is an attempt to know about additional chemical profile of Artemisia macrocephala. Antioxidant activity is performed as the plant is reported to contain flavonoids, which have antioxidant activity in general. Relaxant activity of fractions of crude methanol extract is performed to know in which fraction(s) the relaxant constituents concentrate as we have already reported that its crude methanol has relaxant activity. Antispasmodic activity of essential oil is also performed as the plant is rich with essential oil.Methods: Phytochemical profile of the plant is performed. Free radical scavenging activity was performed using 2, 2-diphenyl-1-picrylhydrazyl (DPPH). Relaxation activity tests of fractions and essential oil of Artemisia macrocephala were performed on sections of rabbits' jejunum. Calcium chloride curves were constructed to investigate the mode of action of plant extracts and its essential oil.Results: We detected carbohydrates, flavonoids and saponins in A. macrocephala. At concentration 0.005 mg/ml, free radical scavenging activity of ethyl acetate fraction was 121.5 ± 2.02% of ascorbic acid.n- hexane fraction relaxed spontaneous activity with EC50 0.74 ± 0.04 mg/ml. Essential oil relaxed spontaneous activity with EC50 0.8 ± 0.034 mg/ml. Chloroform and ethylacetate fractions relaxed both spontaneous and KCl-induced contractions suggesting its possible mode through calcium channels. Constructing calcium chloride curves, the test fractions showed a right shift in the EC50. Essential oil at concentration 0.1 mg/ml produced right shift with EC50 (log [Ca++]M) -2.08 ± 0.08 vs. control with EC50 -2.47 ± 0.07. The curve resembled the curves of verapamil, which caused a right shift at 0.1 μM, with EC50 -1.7 ±0.07 vs. control EC50 (log [Ca++]M) -2.45 ± 0.06.Conclusions: Crude methanol and its fractions (ethyl acetate, chloroform and butanol) are rich sources of antioxidant constituents. The relaxing constituents following calcium channel blocking mechanisms are more concentrated in n-hexane, chloroform and ethyl acetate fractions that warrant isolation. © 2013 Ali et al.; licensee BioMed Central Ltd.

In dense underwater sensor networks (UWSN), the major confronts are high error probability, incessant variation in topology of sensor nodes, and much energy consumption for data transmission. However, there are some remarkable applications of UWSN such as management of seabed and oil reservoirs, exploration of deep sea situation and prevention of aqueous disasters. In order to accomplish these applications, ignorance of the limitations of acoustic communications such as high delay and low bandwidth is not feasible. In this paper, we propose Adaptive mobility of Courier nodes in Threshold-optimized Depth-based routing (AMCTD), exploring the proficient amendments in depth threshold and implementing the optimal weight function to achieve longer network lifetime. We segregate our scheme in 3 major phases of weight updating, depth threshold variation and adaptive mobility of courier nodes. During data forwarding, we provide the framework for alterations in threshold to cope with the sparse condition of network. We ultimately perform detailed simulations to scrutinize the performance of our proposed scheme and its comparison with other two notable routing protocols in term of network lifetime and other essential parameters. The simulations results verify that our scheme performs better than the other techniques and near to optimal in the field of UWSN. © 2013 IEEE. Source
