Run-Length Based Efficient Compression for System-on-Chip
A. Balasubramaniyan,S. Saravanan,Har Narayan Upadhyay
Journal of Artificial Intelligence , 2013,
Abstract: Large test data volume is one of the major problems in the emerging System-on-Chip (SoC) and this can be reduced by test data compression techniques. Variable-to-variable length compression is one among the test data compression techniques. This study demonstrates a variable-to-variable length based compression technique called Run-Length based Efficient Compression. The patterns which are selected for doing compression can be partitioned into blocks having equal width. The partitioned blocks can be compared with the adjacent one and can be merged. A control code is used to denote the number of blocks merged. The proposed method can be tested by calculating the effect of compression on larger ISCAS’89 benchmark circuits.

Abstract: In analog VLSI design, 2-dimensional symmetry stack and block merging are critical for mismatch minimization and parasitic control. In this paper, algorithms for analog VLSI 2-dimensional symmetry stack and block merging are described. Several theoretical results are obtained by studying symmetric Eulerian graph and symmetric Eulerian trail. Based on them, an O(n) algorithm for dummy transistor insertion, symmetric Eulerian trail construction and 2-dimensional symmetry stack construction is developed. The generated stacks are 2-dimensional symmetric and common-centroid. A block merging algorithm is described, which is essentially independent of the topological Eepresentation. Formula for calculating the maximum block merging distance is given. Experimental results show the effectiveness of the algorithms.
Caudal and Penile Blocks Demonstrate Similar Reliability and Efficacy in Pediatric Patients Undergoing Circumcision: A Meta-Analysis  [PDF]
Kiran Malik, Ronald S. Chamberlain
International Journal of Clinical Medicine (IJCM) , 2016, DOI: 10.4236/ijcm.2016.75033
Abstract: Purpose: Circumcision is one of the most common surgeries performed in the pediatric population. Multiple regional analgesic techniques, including caudal (CB) and penile block (PB), have championed as offering optimal analgesia for circumcision in the post-neonatal pediatric population without clear consensus. This meta-analysis sought to investigate CB and PB’s analgesic efficacy and the impact on postoperative analgesic requirements in pediatric circumcisions. Methods: A comprehensive literature search of PubMed, Google Scholar, and Cochrane Library (1966-2016) was completed to identify all published randomized control trials (RCTs). Keywords searched included “circumcision”, “caudal block”, “penile block”, and “analgesia”. Inclusion criteria were limited to the comparison of PB versus CB in children less than 18 years of age and its efficacy towards circumcision. The efficacy, time to first additive analgesia, time to first micturition, duration of prolonged motor blockade, incidence of vomiting, and length of stay were analyzed. Results: 9 RCTs involving 574 children (N = 287 in CB and PB) were included. No differences in analgesic efficacy (relative risk (RR) = 0.983, 95% confidence interval (CI) = 0.95 to 1.02; p = 0.328) or time to first additive analgesia were observed (standardized difference in mean (SDM) = 0.438, 95% CI = -0.04 to 0.92; p = 0.073). Time to first micturition (SDM = 0.680, 95% CI = 0.40 to 0.96; p < 0.001) and motor block duration (SDM = 0.707, 95% CI = 0.19 to 1.22; p = 0.007) were significantly prolonged in patients receiving CB. No differences were observed between groups in regards to the incidence of vomiting (RR = 1.56, 95% CI = 0.91 to 2.67; p = 0.107) and length of stay (SDM = 0.741, 95% CI = -0.05 to 1.53; p = 0.066). Conclusion: CB and PB offer similar analgesic success rates for pediatric patients (age 18 months to 16 years) undergoing circumcision. CB is associated with a trend towards longer duration of analgesia, but is associated with prolonged urinary retention and delayed ambulation. CB use is recommended in non-ambulatory children, whereas PB is recommended in ambulatory children.
An optimal merging technique for high-resolution precipitation products
Roshan Shrestha,Paul Houser,Valentine Anantharaj
Journal of Advances in Modeling Earth Systems , 2011,
Abstract: Precipitation products are currently available from various sources at higher spatial and temporal resolution than any time in the past. Each of the precipitation products has its strengths and weaknesses in availability, accuracy, resolution, retrieval techniques and quality control. By merging the precipitation data obtained from multiple sources, one can improve its information content by minimizing these issues. However, precipitation data merging poses challenges of scale-mismatch, and accurate error and bias assessment. In this paper we present Optimal Merging of Precipitation (OMP), a new method to merge precipitation data from multiple sources that are of different spatial and temporal resolutions and accuracies. This method is a combination of scale conversion and merging weight optimization, involving performance-tracing based on Bayesian statistics and trend-analysis, which yields merging weights for each precipitation data source. The weights are optimized at multiple scales to facilitate multiscale merging and better precipitation downscaling. Precipitation data used in the experiment include products from the 12-km resolution North American Land Data Assimilation (NLDAS) system, the 8-km resolution CMORPH and the 4-km resolution National Stage-IV QPE. The test cases demonstrate that the OMP method is capable of identifying a better data source and allocating a higher priority for them in the merging procedure, dynamically over the region and time period. This method is also effective in filtering out poor quality data introduced into the merging process.
Merger of Compact Binaries in the Context of Gravitational Waves and Short-Lived Gamma-Ray Bursts  [PDF]

Abstract: The discovery of gravitational waves resulting from the merger of two massive black holes (GW150914) has revolutionized our view of merging compact binaries. Recently, the Swope Supernova Survey of the optical counterpart of a gravitational wave event in the NGC 4993 galaxy, GW170817, emanating from the merger of two neutron stars, has triggered a lot of research work. Emphasis has been on comparing the existing theoretical models with the observational data, allowing for the prospect of an even more stringent test of general relativity. The afterglow of this event was observed in a wide range of wavelengths extending from radio waves to gamma rays. In this work, we first explore the evolutionary pathways of compact binary systems following the in-spiral, merger, and ring down sequence. We then proceed to discuss the processes leading to the production of gravitational waves and electromagnetic emission resulting from the merger of compact objects, particularly neutron star binaries and neutron star-black hole systems. We construct a basic inventory of the energy released during the merger of compact binaries in all bands of the electromagnetic spectrum with emphasis on gamma-ray burst emission. The constraints on certain wavelength emissions, such as gamma-ray bursts, are discussed in terms of orbital dynamical instabilities, energy transfer processes, and possible jet orientations with respect to the observer. Finally, we explore the futuristic perspective of the impact of gravitational waves detection on our understanding of the working of the universe.
Proposed Model for Sorting Algorithms
Malika Dawra,Priti
International Journal on Computer Science and Engineering , 2012,
Abstract: An important issue in computer science is ordering a list of items. Sorting is the process of putting data in order; either numerically or alphabetically. Sorting problem has attracted a great deal of research because efficient sorting is important to optimize the use of other algorithms such as binary search. This paper presents a model that will split large array in sub parts and then all the sub parts are processed in parallel using existing sorting algorithms and finally outcome would be merged. To process sub parts in parallel multithreading has been introduced.

Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.512B004
Abstract: DES is a kind of block cipher and before DES encryption the plain text be divided into the same-size blocks. But sometimes the plain text can’t be divided into the exactly size. So padding step is needed to pad the space of the block. The discussion of the block padding is the emphasis of this paper. A new padding method is given and at the last part of the paper the implementation of DES using new padding method is given.
Off Label Use of Exparel in an Axillary Block for Prolonged Postoperative Analgesia  [PDF]

Open Journal of Anesthesiology (OJAnes) , 2015, DOI: 10.4236/ojanes.2015.57030
Abstract: Post-operative analgesia is both necessary for patient comfort and satisfaction. Peripheral nerve block offer both good post-operative analgesia and patient satisfaction, but rarely cover the entire period of post-operative pain. Nonnarcotic drugs are extremely helpful, but with severe pain, narcotics are usually used to help with post-operative pain when the nerve block wears off. However, nausea and vomiting, as well as other side effects associated with narcotic use can be severe and limit their use for post-operative analgesia. The addition of supplements to the local anesthetic used for the nerve blocks can extend the analgesia, but few blocks last greater than 24 hours. We describe the use of a relatively new extended release bupivacaine, Exparel that provide significantly longer analgesia than presently used single shot techniques protocols for extended nerve block analgesia.

Hosam Zaky, Jassem Al Hashmi
Open Journal of Internal Medicine (OJIM) , 2016, DOI: 10.4236/ojim.2016.62008
Abstract: We are reporting a case of acquired complete heart block and long QT interval (a dispersion of repolarization that leads to polymorphic ventricular tachycardia) that has presented with loss of conscious and proved to be due to torsade de pointes. The patient responded well to cardiac pacing and beta blocker therapy. The association of complete acquired heart block and long QT interval is quite rare.
