New methodology for known metabolite identification in metabonomics / metabolomics: topological metabolite identification carbon efficiency (tMICE) [PDF]

open access: yes, 2016
A new, simple-to-implement and quantitative approach to assessing the confidence in NMR-based identification of known metabolites is introduced. The approach is based on a topological analysis of metabolite identification information available from NMR ...

Quantum Control of Qubits and Atomic Motion Using Ultrafast Laser Pulses

open access: yes, 2013
Pulsed lasers offer significant advantages over CW lasers in the coherent control of qubits. Here we review the theoretical and experimental aspects of controlling the internal and external states of individual trapped atoms with pulse trains.

Directed network of substorms using SuperMAG ground‐based magnetometer data [PDF]

open access: yes, 2019
We quantify the spatio‐temporal evolution of the substorm ionospheric current system utilizing the SuperMAG 100+ magnetometers. We construct dynamical directed networks from this data for the first time.

The call-by-need lambda calculus [PDF]

open access: yes, 1998
We present a calculus that captures the operational semantics of call-by-need. The call-by-need lambda calculus is confluent, has a notion of standard reduction, and entails the same observational equivalence relation as the call-by-name calculus.

Influence of the Antarctic ozone hole on the polar mesopause region as simulated by the Canadian Middle Atmosphere Model [PDF]

open access: yes, 2012
It is well established that variations in polar stratospheric winds can affect mesospheric temperatures through changes in the filtering of gravity wave fluxes, which drive a residual circulation in the mesosphere.

Near-infrared spectroscopic cathodoluminescence imaging polarimetry on silicon photonic crystal waveguides [PDF]

open access: yes, 2016
We measure polarization- and wavelength-resolved spectra and spatial emission intensity distributions from silicon photonic crystal waveguides in the near-infrared spectral range using spectroscopic cathodoluminescence imaging polarimetry.
