A social speeded choice-reaction-time task was used to study adaptive behaviours following own and observed actions (errors and correct responses) in cooperative and competitive contexts. After making an erroneous response, the appropriate remedial action to avoid future errors in speeded reaction tasks is to slow down. Consistent with previous results, people indeed slow down following their o...

The first astrophysical results of the VLTI focal instrument AMBER have shown the importance of the differential and closure phase measures, which are supposed to be much less sensitive to atmospheric and instrumental biases than the absolute visibility. However there are artifacts limiting the accuracy of these measures which can be substantially overcome by a specific calibration technique ca...

We recently showed that the time-structure based independent component analysis method from Markov state model literature provided a set of variationally optimal slow collective variables for Metadynamics (tICA-Metadynamics). In this paper, we extend the methodology towards efficient sampling of protein mutants by borrowing ideas from transfer learning methods in machine learning. Our method ex...

OF THE DISSERTATION Comparison of Conventional and Bayesian Analysis for the Ultrasonic Characterization of Cancellous Bone by Amber Mae Groopman Doctor of Philosophy in Physics Washington University in St. Louis, 2014 Professor James G. Miller, Chair This dissertation investigates the physics underlying the propagation of ultrasonic waves in cancellous bone. Although quantitative ultrasound ha...

The fauna of termites (Isoptera) preserved in Early Eocene amber from the Cambay Basin (Gujarat, India) are described and figured. Three new genera and four new species are recognized, all of them Neoisoptera - Parastylotermes krishnai Engel & Grimaldi, sp. n. (Stylotermitidae); Prostylotermes kamboja Engel & Grimaldi, gen. et sp. n. (Stylotermitidae?); Zophotermes Engel, gen. n., with Zophoter...

Interspecies bacterial communication is mediated by autoinducer-2, whose synthesis depends on luxS. Due to the apparent universality of luxS (present in more than 40 bacterial species), it may have an ancient origin; however, no direct evidence is currently available. We amplified luxS in bacteria isolated from 25- to 40-million-year-old amber. The phylogenies and molecular clocks of luxS and t...

We have employed hybrid CASPT2//CASSCF/AMBER calculations to map the (1)L(a)(1pipi*) deactivation path of a single quantum mechanical adenine in a d(A)(10).d(T)(10) double strand in water that is treated at the molecular mechanics level. We find that (a) the L(a) relaxation route is flatter in DNA than in vacuo and (b) the L(a) relaxation energy in DNA is much larger than the stabilization ener...

Abstract Nowadays, face detection and head pose estimation have a lot of application such as recognition, aiding in gaze modeling attention. For these two tasks, it is usually to design different models. However, the model often depends on region interest (ROI) detected advance, which means that serial detector needed. Even lightest will slow down whole forward inference time cannot achieve rea...
