I am the head mentor of PRIMES. From time to time one of our mentors tells me that their project is stuck. I then meet with the mentor and their student to brainstorm possible alternative directions. When students suggest their own direction they are more passionate about it and the project gets unstuck. Sometimes a new direction points away from the original question. But after resolving the n...

Neural-based branch predictors have been among the most accurate in the literature. The recently proposed scaled neural analog predictor, or SNAP, builds on piecewise-linear branch prediction and relies on a mixed analog/digital implementation to mitigate latency as well as power requirements over previous neural predictors. I present an optimized version of the SNAP predictor, hybridized with ...

Simulation results are reported on methods that allow both within group and between group heteroscedasticity when testing the hypothesis that independent groups have identical regression parameters. The methods are based on a combination of extant techniques, but their finite-sample properties have not been studied. Included are results on the impact of removing all leverage points or just bad ...

The basic problem discussed here is the exploitation of symmetry in solving linear systems of equations which are equivariant under a permutation of the indices. It is essentially an overview of the method given in 11] and 10], augmented by a careful discussion of the case of xed points, which was left untreated in these articles.

Skeletal sex estimation is an essential step in any osteoarcheological study; hence, several metric and morphological methods have been developed for this purpose, employing different skeletal elements. This paper has a dual purpose: (1) test the performance of machine learning classification models using worldwide samples cranial postcranial measurements (2) present free web application implem...

This theoretical note aims at studying the role of reference points in generating unemployment volatility. For this purpose, I introduce the notion of reference points in a standard Mortensen-Pissarides model. I obtain two results. First, I find that the obtained model is similar to the one found by Pissarides (2009). Second, I show that the introduction of reference points can increase signifi...
