We designed the Land Information System (LIS) to perform global land surface simulations at a resolution of 1-km or finer in real-time. Such an unprecedented scale and intensity in computing pose many challenges. In this article we will demonstrate some of our unique developments and implementations in high performance computing with a Beowulf Linux cluster, to meet these challenges and reach o...

Generating high quality schedules for distributed applications on a Computational Grid is a challenging problem. Some experiments using Simulated Annealing as a scheduling mechanism for a ScaLAPACK LU solver on a Grid are described. The Simulated Annealing scheduler is compared to a Ad-Hoc Greedy scheduler used in earlier experiments. The Simulated Annealing scheduler exposes some assumptions b...

Rather than focusing on his many scientific successes, Peter Kim, PhD, a biochemist known for his innovative work in developing and shepherding drugs to market, chose instead to tell the School of Medicine’s graduating class of 2016 about one of his key failures. “The greatest scientific failure in my career was when I had to stop a clinical trial of a vaccine for HIV/AIDS. And it came just as ...

BACKGROUND Hyperthermia is considered an efficient complement in the treatment of head and neck squamous cell carcinoma (HNSCC). Hyperthermia induces cell apoptosis in a temperature- and time-dependent manner. However, the molecular mechanism of hyperthermia remains unclear. The aim of this study was to investigate the mechanism of apoptosis induced by ultrasound hyperthermia in HNSCC cell line...

Developmental biologist Lucy Shapiro, PhD, told 2015 graduates of the School of Medicine how, as a basic scientist who spent most of her life studying singlecelled bacteria, she stepped out of her laboratory and onto the global stage to try to help the world avert a potential disaster. “About 15 years ago, I sat up and looked around me and found that we were in the midst of a perfect storm,” sa...

Penelitian ini bertujuan untuk melihat sebaran salinitas di perairan Provinsi Bengkulu pada saat kejadian IOD positif kuat yang terjadi tahun 2019. Daerah penelitian adalah wilayah berada posisi hingga dan menggunakan data arus zonal perkedalaman, temperatur perkedalaman salinitas. Untuk peta sebaran, kemudian diolah software GrADS (The Grid Analysis and Display System). Analisis digunakan diag...

Some research on sound source estimation by blind source separation (BSS) have been achieved and been satisfactory. On the aspect of sound source identification of rotating machine, some research is been achieved too. How to apply blind source separation to fault character identification and improve veracity of fault diagnosis is the research content of this paper. Based on the principle of min...
