Twisted K-theory of differentiable stacks [PDF]

open access: yes, 2004
In this paper, we develop twisted $K$-theory for stacks, where the twisted class is given by an $S^1$-gerbe over the stack. General properties, including the Mayer-Vietoris property, Bott periodicity, and the product structure $K^i_\alpha \otimes K^j_ ...

Clinical Pharmacology of Fentanyl in Preterm Infants. A Review

open access: yesPediatrics and Neonatology, 2015
Fentanyl is a synthetic opioid that is very important in anesthetic practice because of its relatively short time to peak analgesic effect and the rapid termination of action after small bolus doses. The objective of this survey is to review the clinical

Groupoid Actions on Fractafolds [PDF]

open access: yes, 2014
We define a bundle over a totally disconnected set such that each fiber is homeomorphic to a fractal blowup. We prove that there is a natural action of a Renault-Deaconu groupoid on our fractafold bundle and that the resulting action groupoid is a ...

Generalized covering space theories [PDF]

open access: yes, 2015
In this paper, we unify various approaches to generalized covering space theory by introducing a categorical framework in which coverings are defined purely in terms of unique lifting properties.

Stationary Markov equilibria for approximable discounted stochastic games [PDF]

open access: yes, 2016
We identify a new class of uncountable-compact discounted stochastic games for which existence of stationary Markov equilibria can be established and we prove two new existence results for this class.

AUGlasses: Continuous Action Unit based Facial Reconstruction with Low-power IMUs on Smart Glasses

open access: yes
Recent advancements in augmented reality (AR) have enabled the use of various sensors on smart glasses for applications like facial reconstruction, which is vital to improve AR experiences for virtual social activities. However, the size and power constraints of smart glasses demand a miniature and low-power sensing solution.
