The Effect of the Distribution of the Inverse Growth Rate on Pancreatic Cancer Progression
Proceedings - Winter Simulation Conference, 2019-December, 1044–1054.
Contributors: L. Abu-El-Haija*, J. Ivy *, O. Ozaltin n & W. Park *
TL;DR:
It was found that the tumor timeline is about nine months longer under the assumption that the inverse growth rate follows Gamma distribution, while it was inconclusive whether tumor progression is faster or slower in older patients as the tumor progression models with the different underlying assumptions on the inversegrowth rate yielded opposite results.

An embarrassingly parallel method for large-scale stochastic programs
In Springer Optimization and Its Applications (Vol. 149, pp. 127–151).
Contributors: B. Sandıkçı * & O. Özaltın n
TL;DR:
This chapter reviews recent developments in solving large-scale stochastic programs, and focuses on a scenario decomposition-based bounding method, which is broadly applicable as it does not rely on special problem structure and stands out as a natural candidate for implementation in a distributed fashion.

Time series anomaly detection from a markov chain perspective
Proceedings - 18th IEEE International Conference on Machine Learning and Applications, ICMLA 2019, 1000–1007.
TL;DR:
This paper introduces a new method for the pattern-wise anomaly detection problem, which aims to find segments whose behaviors are different from the rest of the segments in the time series (as opposed to finding a single data-point in classic anomaly detection problems).

Evaluation of the geometric accuracy of computed tomography and microcomputed tomography of the articular surface of the distal portion of the radius of cats
AMERICAN JOURNAL OF VETERINARY RESEARCH, 80(10), 976–984.
MeSH headings : Animals; Cats / anatomy & histology; Humans; Radius / diagnostic imaging; Reproducibility of Results; X-Ray Microtomography / veterinary
TL;DR:
Articular surface models derived from CT images had dimensional errors that approximately matched the voxel size and therefore CT cannot be used to plan conforming arthroplasties in small joints and could lack precision when use to plan the correction of a limb deformity or repair of a fracture.

TL;DR:
The authors examine the very important problem of managing starts into a wafer fab during the ramps-up of new capacity, and find that maintaining starts slightly below constraint capacity to reduce cycle times can actually increase total output over the ramp-up duration.
