A Hard Look at Blood Sampling of Birds

A Hard Look at Soft Concepts

What can only humans do? What can humans do that machines cannot? These questions have long been tantalizing scientists and philosophers. Many areas, such as creativity and humor, are traditionally considered to be outside the reach of computers. We believe that these territories define an intriguing set of challenges for computer science. We present two approaches for tackling such challenges ...

A Fresh Look at Generalized Sampling

Discretization and reconstruction are fundamental operations in computer graphics, enabling the conversion between sampled and continuous representations. Major advances in signal-processing research have shown that these operations can often be performed more efficiently by decomposing a filter into two parts: a compactly supported continuous-domain function and a digital filter. This strategy...

Another Look at Rejection Sampling Through Importance Sampling

We provide a different view of rejection sampling by putting it in the framework of importance sampling. When rejection sampling with an envelope function g is viewed as a special importance sampling algorithm, we show that it is inferior to the importance sampling algorithm with g as the proposal distribution in terms of the Chi-square distance between the proposal distribution and the target ...

A Look at the Challenges of Boundary-Spanner Academic Leaders

The present study was an exploratory sequential mixed method approach, so the qualitative section of the study was done by descriptive phenomenology method. The participants in the qualitative section included academic administrators with managerial experience who by criterion sampling and saturation in the research findings, 12 were selected for the interview. Research tools in the section wer...
