Motion Imitation Based on Sparsely Sampled Correspondence
Existing techniques for motion imitation often suffer a certain level of
latency due to their computational overhead or a large set of correspondence
samples to search. To achieve real-time imitation with small latency, we
present a framework in this paper to reconstruct motion on humanoids based on
sparsely sampled correspondence. The imitation problem is formulated as finding
the projection of a point from the configuration space of a human's poses into
the configuration space of a humanoid. An optimal projection is defined as the
one that minimizes a back-projected deviation among a group of candidates,
which can be determined in a very efficient way. Benefited from this
formulation, effective projections can be obtained by using sparse
correspondence. Methods for generating these sparse correspondence samples have
also been introduced. Our method is evaluated by applying the human's motion
captured by a RGB-D sensor to a humanoid in real-time. Continuous motion can be
realized and used in the example application of tele-operation.Comment: 8 pages, 8 figures, technical repor

Anxiolytic effects of exogenous intranasal testosterone in humans
Higher levels of testosterone have been associated with fewer anxiety symptoms and greater psychological wellbeing. However, additional research is needed to advance the clinical use of testosterone in mental healthcare. This dissertation aims to investigate the anxiolytic effects of testosterone in men and women through three studies. The first study examines the pharmacokinetic profile of a novel testosterone nasal spray, designed for the safe and rapid delivery of exogenous testosterone in men and women. The second study leverages the utility of this novel spray preparation, and investigates the effect of intranasal testosterone on subjective anxiety during a psychosocial challenge. The final study extends the anxiolytic effects of exogenous testosterone in women, and explores the effect of intranasal testosterone on test anxiety and cognitive performance. Collectively, these three studies aim to contribute to a broader understanding of the anxiolytic effects of testosterone, and with it, the potential for testosterone to act as a novel pharmaceutical in the treatment of anxiety.Psycholog
