Two Paradigms Are Better Than One, and Multiple Paradigms Are Even Better

During the past half century, the field of artificial intelligence has developed a large number of theories, paradigms, technologies, and tools. Many AI systems are based on one dominant paradigm with a few subsidiary modules for handling exceptions or special cases. Some systems are built from components that perform different tasks, but each component is based on a single paradigm. Since peop...

Two Are Better than One?

This paper uses Markov-switching specifications to create a hybrid model with time-varying loading on each of chartist and fundamentalist approaches. The empirical data include the U.S. dollar exchange rates of four Asian tiger countries’ currencies including NTD, SGD, HKD and KOW from 1980 to 2000. Our empirical findings are consistent with the following notions. First, the forecasting perform...

When two kinases are better than one

When two kinases are better than one V idal-Eychenié et al. describe how two protein kinases team up to respond to DNA damage at stalled replication forks. DNA-dependent protein kinase catalytic subunit (DNA-PKcs) promotes the repair of DNA double-strand breaks (DSBs) by nonhomologous end joining (NHEJ). The ATR kinase, on the other hand, initiates cell cycle arrest and DNA repair after recogni...

Bilateral Versus Single Internal Thoracic Artery Grafts

PURPOSE OF REVIEW Several advances have been made in recent years to improve outcome for patients with coronary artery disease. One of the most debated topics regarding surgical treatment with coronary artery bypass grafting (CABG) is graft selection. This review aims to present the current status and scientific evidence for bilateral internal thoracic artery (BITA) grafting. RECENT FINDINGS ...
