CARP: Handling Silent Data Errors and Site Failures in an Integrated Program and Storage Replication Mechanism

Lanyue Lu, Prasenjit Sarkar, Dinesh Subhraveti, Soumitra Sarkar, Mark Seaman, Reshu Jain, Ahmed Bashir
2009 2009 29th IEEE International Conference on Distributed Computing Systems  
This paper presents CARP, an integrated program and storage replication solution. CARP extends program replication systems which do not currently address storage errors, builds upon a record-and-replay scheme that handles nondeterminism in program execution, and uses a scheme based on recorded program state and I/O logs to enable efficient detection of silent data errors and efficient recovery from such errors. CARP is designed to be transparent to applications with minimal run-time impact and

We implemented CARP as a prototype on the Linux operating system and conducted extensive sensitivity analysis of its overhead with different application profiles and system parameters. In particular, we evaluated CARP with standard unmodified email, database, and web server benchmarks and showed that it imposes acceptable overhead while providing sub-second program state recovery times on detecting a silent data error.

RNAi mediated down regulation of myo-inositol-3-phosphate synthase to generate low phytate rice

Nusrat Ali, Soumitra Paul, Dipak Gayen, Sailendra Sarkar, Swapan K Datta, Karabi Datta
2013 Rice  
Phytic acid (InsP 6 ) is considered as the major source of phosphorus and inositol phosphates in cereal grains. Reduction of phytic acid level in cereal grains is desirable in view of its antinutrient properties to maximize mineral bioavailability and minimize the load of phosphorus waste management. We report here RNAi mediated seed-specific silencing of myo-inositol-3-phosphate synthase (MIPS) gene catalyzing the first step of phytic acid biosynthesis in rice. Moreover, we also studied the
more » ... sible implications of MIPS silencing on myo-inositol and related metabolism, since, first step of phytic acid biosynthesis is also the rate limiting step of myo-inositol synthesis, catalyzed by MIPS. Results: The resulting transgenic rice plants (T 3 ) showed a 4.59 fold down regulation in MIPS gene expression, which corresponds to a significant decrease in phytate levels and a simultaneous increment in the amount of inorganic phosphate in the seeds. A diminution in the myo-inositol content of transgenic plants was also observed due to disruption of the first step of phytic acid biosynthetic pathway, which further reduced the level of ascorbate and altered abscisic acid (ABA) sensitivity of the transgenic plants. In addition, our results shows that in the transgenic plants, the lower phytate levels has led to an increment of divalent cations, of which a 1.6 fold increase in the iron concentration in milled rice seeds was noteworthy. This increase could be attributed to reduced chelation of divalent metal (iron) cations, which may correlate to higher iron bioavailability in the endosperm of rice grains. Conclusion: The present study evidently suggests that seed-specific silencing of MIPS in transgenic rice plants can yield substantial reduction in levels of phytic acid along with an increase in inorganic phosphate content. However, it was also demonstrated that the low phytate seeds had an undesirable diminution in levels of myo-inositol and ascorbate, which probably led to sensitiveness of seeds to abscisic acid during germination. Therefore, it is suggested that though MIPS is the prime target for generation of low phytate transgenic plants, down-regulation of MIPS can have detrimental effect on myo-inositol synthesis and related pathways which are involved in key plant metabolism.

Optimized Design Implementation of Direct Memory-Based Hardware for Efficient Resource- Constraint Digital Signal Processing Systems

Nandita Jaiswal, Soumitra Sarkar
2016 International Journal of Engineering Research and  
An advance approach for Direct-Memory-Based hardware for area-delay-power efficient systems for commonly encountered computation-intensive cores of digital signal processing (DSP) systems is presented by combining three techniques, where the memory-size is reduced to one-eighth at the cost of some increase in combinational circuit complexity for signed magnitude numbers. Each of these techniques results in the reduction of the memory size by a factor of two. It is shown that by efficiently

The proposed design for small input sizes can be used for efficient implementation of high-precision multiplication by input operand decomposition. The proposed optimized design also offers almost 87.5% and 85% reductions in direct-memory size for L=5 bits and L=6 bits signed-magnitude numbers respectively, over conventional direct-memory size. Keywords-Digital signal processing (DSP), direct-memorybased computing, very large scale integration (VLSI).

Characteristics of document similarity measures for compliance analysis

Asad Sayeed, Soumitra Sarkar, Yu Deng, Rafah Hosn, Ruchi Mahindru, Nithya Rajamani
2009 Proceeding of the 18th ACM conference on Information and knowledge management - CIKM '09  
Due to increased competition in the IT Services business, improving quality, reducing costs and shortening schedules has become extremely important. A key strategy being adopted for achieving these goals is the use of an asset-based approach to service delivery, where standard reusable components developed by domain experts are minimally modified for each customer instead of creating custom solutions. One example of this approach is the use of contract templates, one for each type of service

This paper describes the use of document similarity measures -Cosine similarity and Latent Semantic Indexing -to identify the top candidate templates on which a more detailed (and expensive) compliance analysis can be performed. Comparison of results of using the different methods are presented.

2017 Journal of Applied and Natural Science  
In our present report, we evaluated seven rapeseed mustard cultivars at coastal saline zone of West Bengal, India under rice-mustard sequence in a triplicated randomized block design for 14 traits to study their performance under late sown (2nd December) condition. The cultivars were sown at 30 cm × 10 cm spacing during winter of 2013−14 and 2014−15. The soil was clay in texture and had the following key properties for the 0−30 cm layer: pH 5.84, electrical conductivity (EC) 1.55 dS/m,

Among the seven cultivars, Kranti produced significantly (p≤0.05) higher seed yield (1.33 t/ha) closely followed by the hybrids PAC-409 (1.23 t/ha) and Pusa Bold (1.21 t/ha). Seed yield showed significant (p≤0.05) positive correlation with all the independent variables (plant height, R2=0.88; dry matter, R2=0.42; days to 50 % flowering, R2=0.27; number of siliqua/plant, R2=0.38; seeds/siliqua, R2=0.48; except number of fertile plants/m2, R2=-0.06; number of secondary branches/plant, R2=-0.97 and length of siliqua, R2=-0.07). However, number of secondary branches/plant had significant (p≤0.05) and negative correlation with seed yield of mustard (R2=-0.97). Plant height revealed the highest degree of correlation (R2=0.88) with seed yield followed by siliqua per main branch (R2=0.77), days to harvest (R2=0.75) and 1000-seed weight (R2=0.52). The results indicated that selection of suitable rapeseed mustard cultivars based on these traits would be more effective in improving seed yield in mustard.

2010 PLoS ONE  
Multi drug resistance (MDR) or cross-resistance to multiple classes of chemotherapeutic agents is a major obstacle to successful application of chemotherapy and a basic problem in cancer biology. The multidrug resistance gene, MDR1, and its gene product P-glycoprotein (P-gp) are an important determinant of MDR. Therefore, there is an urgent need for development of novel compounds that are not substrates of P-glycoprotein and are effective against drug-resistant cancer. Methodology/Principal
more » ... ings: In this present study, we have synthesized a novel, redox active Fe (II) complex (chelate), iron N-(2-hydroxy acetophenone) glycinate (FeNG). The structure of the complex has been determined by spectroscopic means. To evaluate the cytotoxic effect of FeNG we used doxorubicin resistant and/or sensitive T lymphoblastic leukemia cells and show that FeNG kills both the cell types irrespective of their MDR phenotype. Moreover, FeNG induces apoptosis in doxorubicin resistance T lymphoblastic leukemia cell through mitochondrial pathway via generation reactive oxygen species (ROS). This is substantiated by the fact that the antioxidant N-acetyle-cysteine (NAC) could completely block ROS generation and, subsequently, abrogated FeNG induced apoptosis. Therefore, FeNG induces the doxorubicin resistant T lymphoblastic leukemia cells to undergo apoptosis and thus overcome MDR. Conclusion/Significance: Our study provides evidence that FeNG, a redox active metal chelate may be a promising new therapeutic agent against drug resistance cancers.

2013 PLoS ONE  
Phytic acid (InsP 6 ) is considered to be the major source of phosphorus and inositol phosphates in most cereal grains. However, InsP 6 is not utilized efficiently by monogastric animals due to lack of phytase enzyme. Furthermore, due to its ability to chelate mineral cations, phytic acid is considered to be an antinutrient that renders these minerals unavailable for absorption. In view of these facts, reducing the phytic acid content in cereal grains is a desired goal for the genetic

In the present study, we report the RNAi-mediated seed-specific silencing (using the Oleosin18 promoter) of the IPK1 gene, which catalyzes the last step of phytic acid biosynthesis in rice. The presence of the transgene cassette in the resulting transgenic plants was confirmed by molecular analysis, indicating the stable integration of the transgene. The subsequent T 4 transgenic seeds revealed 3.85-fold down-regulation in IPK1 transcripts, which correlated to a significant reduction in phytate levels and a concomitant increase in the amount of inorganic phosphate (Pi). The low-phytate rice seeds also accumulated 1.8-fold more iron in the endosperm due to the decreased phytic acid levels. No negative effects were observed on seed germination or in any of the agronomic traits examined. The results provide evidence that silencing of IPK1 gene can mediate a substantial reduction in seed phytate levels without hampering the growth and development of transgenic rice plants.

Patients diagnosed as type 2 diabetes mellitus were included in the study. The demographic data, disease data and utilization of different classes of oral hypoglycaemic agents and insulin as well as other individual drugs were analysed using the World Health Organization (WHO) indicators for drug utilization studies. Results: The study population was predominantly male (61.33%) and nearly a third (30.9%) belonged to the age group of 50-59 years. Co-morbid conditions were found in 74% patients, among which hypertension (51.1%) was the most common co-morbid condition. The average number of drugs per prescription was 4.22 and the average number of antidiabetic drugs per prescription was 2.18. Metformin was the most commonly prescribed drug (79.6%), followed by sulfonylurea class of drugs (66.9%). Nearly 17.7% patients were on insulin preparations. Glimepiride and metformin was the most common combinations used (45.5%). Antibiotics were included in 15.5% prescriptions and proton pump inhibitors were prescribed in 32% cases. All the medicines were prescribed as generics and injections were prescribed in 17.7% cases. Conclusions: This study gives a picture of the pattern of drug use among diabetes patients in our set up. While metformin was the commonest drug used, glimepiride and metformin combination was the commonest combination therapy.

Introduction Health is a primary concern for every people. If health is good then everything is fine. A person always tried to fit themselves and wants to enjoy healthy life. Technology and health are very much interconnected to each other. Nowadays majority people of our society are conscious about their health and always they are trying to take care of their health. By the use of technological gadgets (viz. their cell phones, tablets and laptops etc.) people can easily conduct virtual visits to doctors, nurses and caregivers. They can also easily get information about medicine and symptoms of diseases by the use of online search engine such as Google through the Internet. New technologies provide people with primary care at home; it seems that there is further potential for getting more benefits by using relevant medical technologies. Indeed those have the power to improve individual and public health, transforming the quality of health care and reducing the cost of health care services. It can give patients and citizens more control over their health and well-being, reduce the administrative burdens for care professionals, and support the development of new medicines and treatments, for instance.
