Quantitative Fluorescent-PCR: Current Scenario and Future Approach for the Investigations of Spontaneous Miscarriages in Karachi

Chromosomal numerical aberration is one of the leading reasons behind spontaneous pregnancy loss. The probability of spontaneous miscarriage increases with advance parental age. After miscarriage patients and their families feel desperate, which consequently create psychological illness. The review evaluates current techniques being used in the diagnosis and focuses toward a recently introduced molecular technique Quantitative Fluorescent-PCR (QF-PCR) which based on the use of fluorescent primers (probes). Several published articles were selected for the review regarding the frequency of spontaneous miscarriages, its reasons, and outcomes. Studies that focus on QF-PCR, karyotyping and their comparison were included. Current situation of management of spontaneous miscarriages was also observed through surveys and consultant views in Karachi. On the basis of the above mentioned piece of information, QF-PCR would be a good addition in the field of prenatal diagnosis. However, karyotyping is also a reliable method of prenatal diagnosis with little limitations.
Elite athletes' perception of retirement support systems

Among factors that affect the success within the sports system is the support service for the development of athlete's career and retirement. The purpose of this study is to investigate the perception of athletes on available post-sports career assistance. The study included 379 athletes associated to the official organizations and/or benefit by the government program to high-performance athletes. It was used a structured questionnaire, from which the response rate was checked. Results showed that 43.2% report that the concentration on being high-performance is negatively affected by the concerns about the future, 74.7% claim the post-sport career assistance is insufficient developed, and 78.3% emphasize that career prospects after retirement are a serious problem. The results suggest that is necessary to improve the support for post-sport career athletes and perhaps take advantage of the knowledge of the former athletes as a potential workforce in areas related to sporting.
Single Document Text Summarization Using Clustering Approach Implementing for News Article

Text summarization is an old challenge in text mining but in dire need of researcher's attention in the areas of computational intelligence, machine learning and natural language processing. We extract a set of features from each sentence that helps identify its importance in the document. Every time reading full text is time consuming. Clustering approach is useful to decide which type of data present in document. In this paper we introduce the concept of k-mean clustering for natural language processing of text for word matching and in order to extract meaningful information from large set of offline documents, data mining document clustering algorithm are adopted. Traditional documents clustering algorithms use the full- text in the documents to generate feature vectors. Such methods often produce unsatisfactory results because there is much noisy information in documents. The varying-length problem of the documents is also a significant negative factor affecting the performance. This technique retrieves important sentence emphasize on high information richness in the sentence as well as high information retrieval. These multiple factors help to maximize coverage of each sentence by taking into account the sentence relatedness to all other document sentence. These related maximum sentence generated scores are clustered to generate the summary of the document. Thus we use k-mean clustering to these maximum sentences of the document and find the relation to extract clusters with most relevant sets in the document, these helps to find the summary of the document. The main purpose of k-mean clustering algorithm is to generate pre define length of summary having maximum informative sentences. In this paper we present the approach for automatic text summarization by extraction of sentences from the Reuters-21578 corpus which include newspaper articles and used clustering approach for extraction summary. Work done for Text Summarization is given in the section (II). Section (III) provided our methodology for Text Summarization, Section (IV) provide the result of our text summarization system.

A Visual Teaching and Learning Environment for the Open Shortest Path First Routing Protocol

In this paper we present Easy-OSPF, an implementation of the Open Shortest Path First (OSPF) protocol developed in C#. Its main goal is to be used as a didactic application in introductory and advanced network courses to support the teaching and learning of OSPF. It allows clarifying the complex and abstract theory of OSPF through virtual laboratories using graphics, images, and animations, which can be easily transformed in knowledge. Easy-OSPF offers a user-friendly, flexible and robust graphical user interface that allows users to configure all relevant aspects of the network and the OSPF protocol. It also provides a network viewer, an integrated sniffer, and a protocol table viewer. The initial teaching experiments that we conducted with the usage of Easy-OSPF indicate that it can dramatically facilitate the learning of OSPF. Additionally, Easy-OSPF can be used in a production network as a functional but limited implementation of the OSPF protocol.
Actor 3D reconstruction by a scene-based, visual hull guided, multi-stereovision framework

This paper proposes a novel framework to produce 3D, high-precision models of humans from multi-view capture. This method’s inputs are a visual hull and several sets of multi-baseline views. For each such view set, a surface is reconstructed with a multi-baseline stereovision method, then used to carve the visual hull. Carved visual hulls from different view sets are then fused pairwise to deliver the intended 3D model. The contributions of this paper are threefold: (i) the addition of visual hull guidance to a multi-baseline stereovision method, (ii) a carving solution to a visual hull from an interpolated and smooth stereovision surface, and (iii) a fusion solution to merge differently carved volumes differing in several areas. The paper shows that the proposed approach helps recovering a high quality carved volume, a 3D representation of the human to be modelled, that is precise even for small details and in concave areas subjected to occlusion.
Knowledge Management in Lean Product Development

Increased globalization and competitiveness puts higher demands on companies to manage and create knowledge in the company. More specifically is Product Development an area where knowledge handling is of great importance due to e.g. increasing demands on shorter development cycles and the large costs of unplanned loop-backs. The purpose of this master thesis was to investigate tools and methods in the Lean Product Development concept to manage knowledge. The purpose was fulfilled by answering the following research questions:  What role does Knowledge Management have in Lean PD?  What tools and methods from Lean PD are companies using to manage knowledge?  What are the benefits of the tools and methods? This was carried out with a literature study, a broad survey to 47 Swedish based industry companies, case studies at Swedish Lean PD companies and interviews with Swedish Lean PD experts in the area. In literature, KM has a large role in Lean PD and is described as the core of a successful Lean PD initiative. Furthermore, to manage knowledge is a significant part of Lean PD tools and methods. Of the more Lean PD specific tools and methods, the most commonly used, are according to the survey; Checksheets (59%), Set-based design (56%), Obeya (53%) and A3s (47%). The tool that is used significantly less frequent is Trade-off curves that only one of the companies have implemented fully. It is important to clarify that coherency was found between literature, survey, case study companies and experts that tools and methods are only one part of Lean PD and that a culture needs to be in place to support the Lean PD effort to succeed. It is found that the benefits gained from using Lean PD tools and methods are completely dependent on how the company is using them. The tools and methods are according this research helping to manage knowledge but to a much smaller extent than were found in the literature, probably due to how they are used in companies. Moreover, companies need to select and adapt the tools and methods to suit their organization. If this is successful, and the tools and methods are used at its’ fully potential, a better knowledge sharing and knowledge creating organization will occur. However the largest separate benefits found at the survey companies from using A3s, Set-based design and Checksheets are better basis for decision making. Finally it can be argued that the facilitation of making decisions is due to increased knowledge and knowledge sharing.
Eukaryotic biodiversity of Arctic and Antarctic sea ice – a molecular approach

Sea ice covers extensive areas of the polar regions. The conditions within and around the ice are highly variable. This results in many different habitats for organisms, ranging from protozoans to huge animals. The investigation of sea ice in general is difficult, that is why no spatial or temporal coverage of sampling sites was possible so far. The observation and description of sympagic communities were usually done by various microscopic techniques. The detectable biodiversity can be increased by methods which base on the identification of characteristic DNA fragments. This approach allows the analysis of organisms, which are too small for light-microscopy, not distinguishable by its morphology or very rare. A well known method for other ecosystems is sequencing of 18S libraries which provides a highly conserved fragment of all eukaryotes in the sample for sequence analysis. The aim of the present study is to use 18S libraries to analyse the eukaryotic biodiversity of sea ice and to estimate its advantages and boundaries. Samples from Van Mijenfjorden on Svalbard (Arctic) and from the Weddel Sea (Antarctica) were analysed by sequencing of 18S clone libraries and compared concerning their biodiversity. The samples originated from sea ice which differed in the generic ice class and its age, for instance. Therefore, assumptions about the influence of biotic and abiotic conditions on the biodiversity were possible. The resulting phylogenetic trees varied significantly, whereas the biodiversity was mainly influenced by the processes during sea-ice formation and ageing. At the Antarctic stations, also biochemical parameters were measured. These data allow the comparison with former investigations which used microscopic methods. The results clearly show similar species compositions, even though the influence of various factors makes significant conclusions difficult. The Arctic samples were compared with results from expeditions in the southwest of Svalbard. In the present study, surprisingly low numbers of bacillariophyta were found, which is maybe related to the extremely low temperature during this winter or to the influence of the coast nearby. This study represents a first step into the high-throughput analysis of sea-ice biodiversity by using 18S PCR. For protozoa and metazoa, results agreed in general with those of other identification methods. A quantification of the observed class and kingdoms is not reasonable, especially for metazoa. Descriptions on species-level would require additional primers and sequencing reactions which is difficult for a high-throughput approach but also not necessary for a first large scale monitoring of sea-ice biodiversity.
Unidirectional lasing in semiconductor microring lasers at an exceptional point [Invited]

Recent experiments demonstrated that chiral symmetry breaking at an exceptional point (EP) is a viable route to achieve unidirectional laser emission in microring lasers. By a detailed semiconductor laser rate equation model, we show here that unidirectional laser emission at an EP is a robust regime. Slight deviations from the EP condition can break preferential unidirectional lasing near threshold via a Hopf instability. However, above a “second” laser threshold, unidirectional emission is restored.
Full silicon-nitride probes with corner lithography wireframes for scanning Hall probe microscopy

We present a improvement of our previous design of wireframe tips for scanning Hall probes. By doubling the separation between electrode structures and cantilever base, the yield could be raised from less than 10% to over 75%. To avoid build up of stress gradients, the entire probe is manufactured from silicon-nitride, using a polysilicon sacrificial layer. In this paper cantilever stress measurement and Initial electrical characterization are presented.
Varieties of Capitalism and Investments in Human Capital

This paper explores the relationship between national institutional archetypes and investments in training and development. A recent trend within the literature on comparative capitalism has been to explore the nature and extent of heterogeneity within the coordinated market economies (CMEs) of Europe. Based on a review of the existing comparative literature on training and development, and comparative firm-level survey evidence of differences in training and development practices, we both support and critique existing country clusters and argue for a more nuanced and flexible categorization.
A re-evaluation of phylogenetic relationships within the tribe Tragelaphini (Bovinae: Bovidae), based on complete mitochondrial genomes

In this research, phylogenetic relationships of eight species from the tribe Tragelaphini were evaluated using complete mitochondrial genomes. Today, the most of the species belonging to the tribe Tragelaphini, face the risk of declining generation and extinction and they are on the red list of IUCN. Therefore, recognizing the evolutionary biology of them is a very positive step in preventing their extinction. In present research, the average base composition of mtDNA sequences was 26.9% T, 25.9% C, 33.6% A, and 13.6% G, showing a strong AT bias (60.5%). The phylogenetic trees were investigated using the ML, ME and NJ methods and found that they have very identical topologies. In general, the results of this study were similar to the other molecular phylogenetic studies and in obvious contradiction with the morphological results. For example, Derby eland (Taurotragus derbianus) shows a very close phylogenetic relationship with other members of the tribe Tragelaphini and should not be in a separate genus. Also, in all of the phylogenetic trees, T. imberbis completely was separated from other species and was not located into a single cluster with them. Undoubtedly, the phylogenetic position of this species should be re-examined. In total, the results of current study showed that the complete mitochondrial genomes are very useful, powerful, and accurate tools for evaluating the phylogenetic relationships of the members of the tribe Tragelaphini. Besides, using these genomes, we can meticulously reconstruct and modify their classification.
Coupling Multiphase Hydrodynamic and NMR Pore-Scale Modeling for Advanced Characterization of Saturated Rocks

We use the novel method of the density functional hydrodynamics (DFH) [1 – 4] to model complex multiphase scenarios occurring in natural cores on a pore-scale. Such scenarios may be extremely diverse, ranging from those inherent in RCA and SCAL measurements, and to much more complex processes relevant to chemical EOR. We perform the numerical simulation of several multiphase flow scenarios by means of the direct hydrodynamic (DHD) simulator, which is a numerical code containing implementation of DFH. We have demonstrated some of the capabilities of our numerical tool, DHD, for simulation of multiphase flow previously [4 – 6]. Now we focus on a combination of two different methods for characterization of a multiphase system in pores. The first method comes from hydrodynamic and thermodynamic description obtained through DHD simulation. The second method emerges from numerical modeling of NMR response corresponding to T2 relaxation and pulsed gradient spin-echo (PGSE) experiments [7 – 10], which are routinely conducted not only in laboratory, but also downhole using NMR logging tools. We model the NMR response by solving numerically the generalized Bloch-Torrey equations [11] containing relaxation, diffusion and magnetization transport terms. The equations are subject to boundary conditions describing surface relaxation. The NMR description we use enables performing modeling of T2 relaxation and PGSE experiments, and their combination. The numerical NMR solver is also implemented within the DHD simulator. This facilitates application of NMR modeling (i.e., makes it automatic) to digitized cores with multiphase saturation, whose state has previously been described and simulated in the frame of the DFH. Such close coupling of two characterization methods different by nature is extremely important and brings an opportunity for improvement of NMR response interpretation techniques, which suffer from the inverse and ill-posed nature of the fluids characterization problem.
Impact of Leadership and Communication on Project Success with the Mediating Effect of Affective Commitment in Virtual Projects

Despite growing interest on the issues of communication, leadership style and commitment, studies examining the interplay between all of these three variables are lacking. This paper attempts to address this gap. It draws on survey data involving 225 virtual project managers. Socio-economical changes nowadays have significant influence on the project success rate. The motive quantitative correlational research is inspecting connection among leadership style and communication (independent variable), having the mediating effect of affective commitment what's more, dependent variable, project success in virtual projects. The whole project professionals received 3-part personally administrative questionnaire. Response rate is 93.2%. The findings designated statistically significant relationship among leadership style, communication on project success in virtual projects and affective commitment contributes as mediation in these relationships. This is helpful for virtual project managers. Limitations and future direction have also been discussed. Keywords: leadership: communication, affective commitment and project success
Change in seismicity beneath the Tokyo metropolitan area due to the 2011 off the Pacific coast of Tohoku Earthquake

Static changes in the Coulomb Failure Function (ΔCFF) forecast an increase in seismicity in and around the Tokyo metropolis after the 2011 off the Pacific coast of Tohoku Earthquake (magnitude 9.0). Among the 30,694 previous events in this region with various depth and focal mechanism, almost 19,000 indicate a significant increase of the ΔCFF, while less than 6,000 indicate a significant decrease. An increase in seismicity is predicted in southwestern Ibaraki and northern Chiba prefectures where intermediate-depth earthquakes occur, and in the shallow crust of the Izu and Hakone regions. A comparison of seismicity before and after the 2011 event reveals that the seismicity in the above regions indeed increased as predicted from the ΔCFF.
The Next Generation Virgo Cluster Survey (NGVS). XXXII. A Search for Globular Cluster Substructures in the Virgo Galaxy Cluster Core

Substructure in globular cluster (GC) populations around large galaxies is expected in galaxy formation scenarios that involve accretion or merger events, and it has been searched for using direct associations between GCs and structure in the diffuse galaxy light, or with GC kinematics. Here, we present a search for candidate substructures in the GC population around the Virgo cD galaxy M87 through the analysis of the spatial distribution of the GC colors. The study is based on a sample of ∼1800 bright GCs with high-quality u, g, r, i, z, Ks photometry, selected to ensure a low contamination by foreground stars or background galaxies. The spectral energy distributions of the GCs are associated with formal estimates of age and metallicity, which are representative of its position in a 4D color space relative to standard single stellar population models. Dividing the sample into broad bins based on the relative formal ages, we observe inhomogeneities that reveal signatures of GC substructures. The most significant of these is a spatial overdensity of GCs with relatively young age labels, of diameter ∼0. °1 (∼30 kpc), located to the south of M87. The significance of this detection is larger than about 5σ after accounting for estimates of random and systematic errors. Surprisingly, no large Virgo galaxy is present in this area that could potentially host these GCs. But candidate substructures in the M87 halo with equally elusive hosts have been described based on kinematic studies in the past. The number of GC spectra available around M87 is currently insufficient to clarify the nature of the new candidate substructure.
Exploring an IT Service Change Management Process: A Case Study

IT service providers need effective methods for managing change requests and changes regarding provided IT services and the IT infrastructure. However, many IT service providers consider the implementation of a service- oriented change management process as a difficult task. This challenge has led us to examine the research problem: How to improve a change management process based on IT service management practices? The main contribution of this study is 1) to explore how an IT service provider organization in Finland has implemented a change management process, and 2) to identify what types of challenges are related to the transition process from traditional change management to service-oriented change management. Data for this study were collected by using a case study research method. Keywords-change management; request for change; IT ser- vice
