A growth factor has been isolated from HTCSR rat hepatoma tissue culture cells which specifically stimulates DNA synthesis and cell proliferation of the HTC cells that produce it. The factor can be isolated from HTC cell conditioned medium or from an HTC cell extract. This autocrine factor has been purified 640-fold from a postmicrosomal supernatant by successive steps, involving ethanol precip...

The soluble fractions from both rat liver and an established hepatoma cell line (HTC cells) contain protein kinases and proteins which bind adenosine 3’: 5’-monophosphate (cyclic AMP). Liver cytosol exhibits somewhat more binding activity and less protein kinase activity than HTC cells. Protein kinase activity from both sources is stimulated by cyclic AMP. Scatchard plots for the binding of cyc...

This abstract describes a method for the Multiple Fundamental Frequency (F0) Estimation and Tracking task in the Music Information Retrieval Evaluation eXchange (MIREX) 2007. The method is called Harmonic Temporal Structured Clustering (HTC), which is a kind of constrained Gaussian Mixture Model (GMM) estimation using EM algorithm. It can jointly extract F0, intensity, onset, duration of each u...

In this paper, we present the methods we have proposed and evaluated through the ImageCLEF 2012 Photo Annotation task. More precisely, we have proposed the Histogram of Textual Concepts (HTC) textual feature to capture the relatedness of semantic concepts. In contrast to term frequency-based text representations mostly used for visual concept detection and annotation, HTC relies on the semantic...

The effects of alkalinity on alkaline hydrothermal conversion (alkaline-HTC) of cellulose to bio-oil were investigated in this study. The results showed that the initial alkalinity greatly influenced the reaction pathways. Under initial strong alkaline conditions with final pH greater than 7, alkaline-HTC only followed the alkaline pathway. However, under initial weak alkaline conditions with f...

In most rocks, Natural Remanent Magnetization (NRM) can involve two or more superimposed components. Demagnetizations hopefully result in the separation of these components, which may then be resolved using least-squares regression methods. In a study of Cretaceous redbed sites from Qaidam (China), thermal demagnetization of most specimens revealed 3 rectilinear segments in orthogonal plots, gi...

BACKGROUND HIV transmission among people who inject drugs (PWID) is high in Yunnan and Guangxi provinces in southwest China. To address this epidemic, Population Services International (PSI) and four cooperating agencies implemented a comprehensive harm reduction model delivered through community-based drop-incenters (DiC) and peer-led outreach to reduce HIV risk among PWID. METHODS We used 2...

Checkpointing is a fault-tolerance mechanism commonly used in High Throughput Computing (HTC) environments to allow the execution of long-running computational tasks on compute resources subject to hardware or software failures as well as interruptions from resource owners and more important tasks. Until recently many researchers have focused on the performance gains achieved through checkpoint...

To assist the bioinformatic community in leveraging the national cyberinfrastructure, the National Center for Genomic Analysis Support (NCGAS) along with Indiana University's High Throughput Computing (HTC) group have engineered a method to use the Galaxy to submit BLAST jobs to the Open Science Grid (OSG). OSG is a collaboration of resource providers that utilize opportunistic cycles at more t...
