THE house lights go down, you settle in your seat, and the theater quiets to murmurs of anticipation. The stage lights go up, and, after brief introductions, out walk three men who have shaped our specialty and who continue to shape it. Their names—Severinghaus, Miller, and Shafer—are familiar to most of us as inventors, textbook writers, and researchers, but we are probably a little vague on t...

This is a special issue of the Iranian Journal of Operations Research that includes some of the invited talks presented at the 11th international conference of the Iranian Operations Research Society (IORS), organized jointly by IORS and Razi University of Kermanshah and held at the Razi University, Kermanshah, Iran, May 2-4, 2018. The IORS conference is held annually and is the main event ...

In 2009, Peter Cameron introduced a common generalization of various classes of combinatorial designs such as balanced incomplete block designs, resolvable designs and orthogonal arrays. Generalized covering and packing designs can be defined in analogous way. These objects bring into this framework further classes of designs, including covering and packing arrays, Howell designs, monogamous cy...

Efforts to detect targets of recent positive selection (“selective sweeps”) in the genome frequently involve an initial screen of a region of the genome at a low density of markers (either SNPs or microsatellites), followed by a denser screen in the region flanking markers that show reduced or skewed variation relative to that predicted by an equilibrium neutral model or relative to “background...

This talk concerns Dirichlet and Neumann boundary value problems for second order elliptic divergence form equations with non-symmetric, or more general complex, and measurable coefficients independent of the transversal coordinate in the upper half space. I shall discuss some recent results obtained which shows that, in the case of non-symmetric coefficients, the solutions obtained with the bo...

In the eubacterial cell, the peptidoglycan is perpetually hydrolyzed throughout the cell cycle by different enzymes such as lytic transglycosylases, endopeptidases, and amidases. In Escherichia coli, four N-acetylmuramoyl-l-alanine amidases, AmiA, -B, -C, and -D, are present in the periplasm. AmiA, -B, and -C are soluble enzymes, whereas AmiD is a lipoprotein anchored in the outer membrane. To ...

In team sports, players move in complex but surprisingly predictable ways. With state-of-the-art computer vision and machine learning methods, it is now possible to collect sufficiently large player tracking datasets and learn patterns of how players actually move. In this talk, I will describe how this knowledge has been used at Disney Research to generate new analytics and sports broadcasting...

Our understanding of the notion “dynamic system” is a rather broad one: such a system has states, which can change over time. Ontologies are used to describe the states of the system, possibly in an incomplete way. Monitoring is then concerned with deciding whether some run of the system or all of its runs satisfy a certain property, which can be expressed by a formula of an appropriate tempora...
