This work revisits the processing of stream joins on modern hardware architectures. Our work is based on the recently proposed handshake join algorithm, which is a mechanism to parallelize the processing of stream joins in a NUMA-aware and hardware-friendly manner. Handshake join achieves high throughput and scalability, but it suffers from a high latency penalty and a non-deterministic orderin...

This paper summarizes and includes some text from the prior work The Stream Virtual Machine, by François Labonté, Ian Buck, Peter Mattson, Christos Kozyrakis, and Mark Horowitz, presented at PACT 2004. The stream computing paradigm separates the application's computational kernels from communication streams, matching the structure and performance constraints of modern multiprocessors and data i...

Several query languages have been proposed for managing data streams in modern monitoring applications. Continuous queries expressed in these languages usually employ windowing constructs in order to extract finite portions of the potentially unbounded stream. Explicitly or not, window specifications rely on ordering. Usually, timestamps are attached to all tuples flowing into the system as a m...

We propose to create and study a new model for the micro-typography part of automated multilingual typesetting. This new model will support quality typesetting for a number of modern and ancient scripts. The major innovations in the proposal are: the process is refined into four phases, each dependent on a multidimensional tree-structured context summarizing the current linguistic and cultural ...

Six hot topics in modern planetary astronomy are described: 1) lightcurves and densities of small bodies 2) colors of Kuiper belt objects and the distribution of the ultrared matter 3) spectroscopy and the crystallinity of ice in the outer Solar system 4) irregular satellites of the giant planets 5) the Main Belt Comets and 6) comets and meteor stream parents.

The external irreversible losses of air engines, due to equilibration of the hot and fast exhaust with the environment, are discussed based on the second law of thermodynamics. The effect of the bypass ratio on thermomechanical exergy destruction in the exhaust stream is demonstrated. The analysis gives a strong motivation for the use of high bypass turbo fan engines in modern aircraft.

Seth Gordhandas Sunderdas Medical College and King Edward VII Memorial (KEM) Hospital were established in the year 1926 and in a short span of two decades the twin institutions had created a reputation not only for offering selfless and quality medical service but also for excellence in teaching, research and medical writing. The staff and faculty of the institutions met regularly to discuss th...

Each year, in an attempt to stimulate journalism students' interest in medical writing, CMAJ sponsors the Amy Chouinard Memorial Essay Prize. The $750 award is in memory of Amy Chouinard, a longtime and valued contributor to CMAJ and the Canadian Journal of Surgery. Students from any recognized journalism program at a Canadian college or university are eligible to enter, and the deadline for 19...

The case report, which has a long history in medicine, has seen its fortune wax and wane with time. We discuss the challenges facing the continued survival of the case report, including the inability of journals to cope with the increased load and increased cost of publication, ethical issues, the impact factor and the rise of evidence-based medicine. We highlight the important role that the ca...
