Enhancing the functional content of protein interaction networks
Protein interaction networks are a promising type of data for studying
complex biological systems. However, despite the rich information embedded in
these networks, they face important data quality challenges of noise and
incompleteness that adversely affect the results obtained from their analysis.
Here, we explore the use of the concept of common neighborhood similarity
(CNS), which is a form of local structure in networks, to address these issues.
Although several CNS measures have been proposed in the literature, an
understanding of their relative efficacies for the analysis of interaction
networks has been lacking. We follow the framework of graph transformation to
convert the given interaction network into a transformed network corresponding
to a variety of CNS measures evaluated. The effectiveness of each measure is
then estimated by comparing the quality of protein function predictions
obtained from its corresponding transformed network with those from the
original network. Using a large set of S. cerevisiae interactions, and a set of
136 GO terms, we find that several of the transformed networks produce more
accurate predictions than those obtained from the original network. In
particular, the measure proposed here performs particularly well for
this task. Further investigation reveals that the two major factors
contributing to this improvement are the abilities of CNS measures, especially
, to prune out noisy edges and introduce new links between
functionally related proteins
A Case Study on Physical Properties Blends Analysis of Non-Degradable Films with Gray Back Boards
In the printing and packaging industries blends of non-degradable plastic film and degradable paperboards is very common substrate. The gray back board is recycled pulp paperboard. The gray back boards are one side dull or gray color in physical appearances so it is called gray back paperboard. The gray back paperboards have not good strength and visual appeal as compare to other paperboards. But the printing and packaging industries are mostly using the gray back paperboards because the gray back paperboards are the cheapest material for package preservation, containment and transportation. The blends of gray back paper boards with plastic film gives good combination for packaging industries. This particular research work deals with study of gray back paperboards and plastic film blend
Cloud Computing: Applications, Challenges and Open Issues
Cloud computing is one of the innovative computing, which deals with storing
and accessing data and programs over the Internet [1]. It is the delivery of
computing resources and services, such as storing of data on servers and
databases, providing networking facilities and software development platforms
over the Internet. It provides the flexibility of resources for everyone. These
services are provided via data centers, which are located in various parts of
the world [2, 3]. Cloud computing makes access to these resources to everyone
on a global scale at a very minimal cost and significantly higher speed. These
servers provide services to the users, which would have cost a lot of
computational power to them if they had to buy them. The first mention of cloud
computing was referenced in a Compaq internal document released in 1996 [4].
Cloud computing was then commercialized in 2006 when Amazon released elastic
compute cloud (EC2). Furthermore, Google released Google app engine in 2008 and
Microsoft Azure services were launched in October 2008, which increased the
competition in the area of cloud computing. Since then these companies have
done a lot of development in cloud computing
Mefenamic acid and diclofenac in the treatment of menorrhagia and dysmenorrhea in dysfunctional uterine bleeding: a randomized comparative study
Background: There is a perception that Mefenamic Acid should be the preferred NSAID for menorrhagia. However, there are insufficient evidences to prove this. Further RCTs are required to compare individual NSAIDs.Purposes of the study were to assess and compare the efficacy of mefenamic acid and diclofenac in control of menorrhagia in patients with DUB, to assess and compare their analgesic effects in dysmenorrhea associated with DUB and to study their adverse effects.Methods: Sixty-eight patients were randomized into either Mefenamic Acid (n=34) or Diclofenac (n=34) group. Efficacy variables (Pictorial Blood loss Assessment Chart quantification, Number of pads used, Number of days of menstrual bleeding, Visual Analog Scale score) and adverse effects were recorded over three menstrual cycles.Results: The median reduction of menorrhagia with Mefenamic Acid was 43.39% (Range: 2.86% to 94.4%) and for Diclofenac was 57.5% (Range: 9.9% to 93.58%). The Diclofenac group showed a statistically significant decrease in median bleeding volume, median number of pads used and median number of days of bleeding compared to the Mefenamic Acid group (p<0.05, CI = 95%) but did not show a statistically significant decrease in median VAS score compared to the Mefenamic Acid group. Adverse effects with both groups were mild.Conclusions: Mefenamic Acid and Diclofenac individually managed to significantly reduce excessive bleeding compared to baseline. Diclofenac fared better than Mefenamic Acid in terms of control of excessive menstrual bleeding. Both these agents were able to reduce the menstrual pain and on comparison, were found to be equi-efficacious

An Unusual Cause of Camptocormia
Background: Camptocormia is defined as forward flexion of the spine that manifests during walking and standing and disappears in recumbent position. The various etiologies include idiopathic Parkinson’s disease, multiple system atrophy, myopathies, degenerative joint disease, and drugs.
Case Report: A 67-year-old diabetic female presented with bradykinesia and camptocormia that started 1 year prior to presentation. Evaluation revealed levosulpiride, a dopamine receptor blocker commonly used for dyspepsia, to be the culprit.
Discussion: It is well known that dopamine receptor blockers cause parkinsonism and tardive syndromes. We report a rare and unusual presentation of camptocormia attributed to this commonly used gastrointestinal drug in the Asian population
Bag-Of-Tasks Scheduling on Related Machines
We consider online scheduling to minimize weighted completion time on related
machines, where each job consists of several tasks that can be concurrently
executed. A job gets completed when all its component tasks finish. We obtain
an -competitive algorithm in the non-clairvoyant setting,
where denotes the number of distinct machine speeds. The analysis is based
on dual-fitting on a precedence-constrained LP relaxation that may be of
independent interest.Comment: Preliminary version in APPROX 202
A New Type of Coincidence and Common Fixed-Point Theorems for Modified ð-Admissible ð©-Contraction Via Simulation Function
In this manuscript, we introduce the concept of modified α-admissible contraction with the help of a simulation function and use this concept to establish some coincidence and common fixed-point theorems in metric space. An illustrative example that yields the main result is given. Also, several existing results within the frame of metric space are established. The main theorem was applied to derive the coincidence and common fixed-point results for α-admissible ð’µ-contraction
