Chip Scale Emission of Blue Light at Elevated Temperatures in Optical Waveguides Integrated With Rubidium Vapor

open access: yesLaser &Photonics Reviews, EarlyView.
An integrated atom‐clad waveguide enables chip‐scale blue light generation (420 nm) via a two‐photon ladder transition in rubidium vapor at temperatures up to 240°C. The observed bell‐shaped intensity profile reveals a competitive interplay between local photon generation and macroscopic vapor reabsorption.

Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...

Heart‐Rate Variability and Its Role in Non‐Cardiac Surgery Perioperative Care: Scoping Review

open access: yesANZ Journal of Surgery, EarlyView.
ABSTRACT Background Heart rate variability (HRV) is a non‐invasive method of assessing autonomic function. Those with autonomic dysfunction may be at heightened risk of peri‐operative complications due to sympatho‐parasympathetic imbalance. This review summarises the clinical applications of HRV, approaches to how it is measured, and its role in ...

Establishing Shape Correspondences: A Survey

open access: yesComputer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Scalable Computation of Topological Abstractions for Scalar Data

open access: yesComputer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

A convergent star product on the Poincaré disc

open access: yes, 2019
On the Poincaré disc and its higher-dimensional analogs one has a canonical formal star product of Wick type. We define a locally convex topology on a certain class of real-analytic functions on the disc for which the star product is continuous and ...

Did Perrin's experiments convert Poincaré to Scientific Realism? [PDF]

open access: yes, 2013
In this paper I argue that Poincaré’s acceptance of the atom does not indicate a shift from instrumentalism to scientific realism. I examine the implications of Poincaré’s acceptance of the existence of the atom for our current understanding of his ...

Nonlinear Dynamic Analysis of Rotor Rub-Impact System

open access: yesShock and Vibration, 2019
A dynamic model of a double-disk rub-impact rotor-bearing system with rubbing fault is established. The dynamic differential equation of the system is solved by combining the numerical integration method with MATLAB.
