Sharing the love : a generic socket API for Hadoop Mapreduce
… and the Hadoop Distributed File System (HDFS). HDFS has known scalability limitations due to its single NameNode which holds the entire file system namespace in RAM on one computer. Therefore, the NameNode can only store limited amounts of file names depending on the RAM capacity. The …

P2PHDFS: AN IMPLEMENTATION OF STATISTIC MULTIPLEXED COMPUTING ARCHITECTURE IN HADOOP FILE SYSTEM
… Peer to Peer Hadoop Distributed File System (P2PHDFS) is designed to store and process extremely large-scale data sets reliably. This is a first attempt implementation of the Statistic Multiplexed Computing Architecture concept proposed by Dr. Shi for the existing Hadoop File System (HDFS) to …

Modelling Huntington’s Disease Using Direct Cell Reprogramming
… reprogramming of adult human dermal fibroblasts (HDFs) into induced neural precursor cells (iNPs) that differentiate into neurons using chemically-modified mRNA (cmRNA) encoding the neural development factors SOX2 and PAX6. Importantly, cell reprogramming enables the study of early disease …

DIRECT REPROGRAMMING OF HUMAN FIBROBLASTS INTO CARDIOMYOCYTES
… efficiency in human dermal fibroblasts (HDFs) when working together with GATA4, MEF2C, TBX5, HAND2 and MYOCD (5F). HDFs-generated iCMs exhibited cardiac-like action potential and spontaneously contractility in-vitro. Importantly, SALL4, together with 5F, promotes adult human cardiac …

Characterizing the Role of CDK2AP1 in Primary Human Fibroblasts and Human Embryonic Stem Cells
… somatic cells (primary human dermal fibroblasts (HDFs)) and human embryonic stem cells (hESCs) and specifically assess its impact on proliferation, self-renewal and differentiation. In the first part of this study, using a short-hairpin RNA (shRNA) approach, we investigated the effect of CDK2AP1 …

Low latency data retrieval solutions for big data
… Our caching approach is developed on top of HDFS to optimize the read latency of HDFS. HDFS is primarily suitable for Write Once Read Many (WORM) applications where the number of reads is significantly more than that of writes. In our Intelligent Caching approach, we analyze real world map …

Research on High-performance and Scalable Data Access in Parallel Big Data Computing
… File System(GFS), Hadoop Distributed File System(HDFS) and Quantcast File System(QFS) have been developed. Currently, the Hadoop Distributed File System(HDFS) [20] is the state-of-art and most popular open-source distributed file system for big data processing. It is widely deployed as the bedrock …

Gradients in Collagen Films: Effects of Mechanical and Chemical Properties on Directional Cell Response
… was tested using human dermal fibroblasts (HDFs), fibrosarcoma cells (HT1080s) and rat Schwann cells (RSCs). HDFs showed an unfavourable response to high EDC/NHS crosslinking levels, but increased proliferation with increasing genipin crosslinking. The presence of IKVAV dendrimers enhanced …

Design of a Gel-in-Scaffold Hybrid Substrate for a Multicellular Endometrial Model
… of the gel component. Human dermal fibroblasts (HDFs) were cultured within different substrates to assess their spatial distribution, morphology and interactions with the surrounding matrix. Infiltrating CG into a scaffold (at least 10-XL) significantly reduced the cell-induced matrix contraction …

Biological response to 8-oxoguanine base released during DNA base excision repair
… to the medium of human diploid fibroblasts (HDFs), while other oxidized and unmodified bases had no effect. We address a potential cause-effect relationship between free 8-oxo-Gua and the premature senescence of HDFs as a model for aging. We hypothesize that free 8-oxo-Gua released during DNA …

Multiplexed angiogenic biomarker quantification on single cells
… models including human dermal fibroblasts (HDFs) in vitro, a 2D endothelial/fibroblast co-culture model in vitro, and a patient-derived xenograft (PDX) model of glioblastoma (GBM). I demonstrate VEGF-A165-mediated downregulation of membrane PDGFRα (~25%) and PDGFRβ (~30%) on HDFs, following …

Exploiting Heterogeneity in Distributed Software Frameworks
… We re-design the Hadoop Distributed File System (HDFS) into a multi-tiered storage system that seamlessly integrates heterogeneous storage technologies into the HDFS. We also propose data placement and retrieval policies to improve the utilization of the storage devices based on their …

An adaptive partitioning scheme for ad-hoc and time-varying database analytics
… implementation on top of Apache Spark and HDFS. Our experimental results show that the Amoeba storage system provides improved query performance for ad-hoc workloads, adapts to changes in the query workloads, and converges to a steady state in case of recurring workloads. On a real world …

Reusing software tests for configuration testing: A case study of the Hadoop project
… rate of 41.7% and 48.8%, for Hadoop Common and HDFS, respectively. Further, this thesis conducts in-depth analysis on tests that cannot be effectively reused, categorizes code patterns of these tests that have false positives or negatives, and provides examples on rewriting these tests.
