Technical Perspective: The Beauty of Error-Correcting Codes
Error-correcting codes are the means by which we compensate for interference in communication, and are essential for the accurate transmission and storage of digital data.Error Correction Up to the Information-Theoretic Limit
Ever since the birth of coding theory almost 60 years ago, researchers have been pursuing the elusive goal of constructing the "best codes," whose encoding introduces the minimum possible redundancy for the level of noise they …Technical Perspective: Where Biology Meets Computing
Alan Turing died in 1954 in his laboratory after eating a cyanide-laced apple. During his last years, Turing had become interested in bio-chemical systems. He had proposed a reaction-diffusion model in his 1952 paper entitled …Learning and Detecting Emergent Behavior in Networks of Cardiac Myocytes
We address the problem of specifying and detecting emergent behavior in networks of cardiac myocytes, spiral electric waves in particular, a precursor to atrial and ventricular fibrillation.COLUMN: Last byte
