Inference for epidemic models with time‐varying infection rates: Tracking the dynamics of oak processionary moth in the UK

Ecology and Evolution, 2022
Invasive pests pose a great threat to forest, woodland, and urban tree ecosystems. The oak processionary moth (OPM) is a destructive pest of oak trees, first reported in the UK in 2006.

Diffractive oblique plane microscopy [PDF]

, 2019
Imaging of neuronal activity with fluorescent indicators is an important technique in neuroscience. However, it remains challenging to record volumetric image data at fast frame rates and good resolution.

Are there real orthogonal polarization modes in pulsar radio emission? [PDF]

, 2000
The Orthogonal Polarization Modes (OPM) have been reported observationally and accepted widely by pulsar researchers. However, no acceptable theory can show the origin of the OPM, which becomes a mystery in pulsar research field.

Design study of time-preserving grating monochromators for ultrashort pulses in the extreme-ultraviolet and soft X-rays [PDF]

, 2017
The design of grating-based instruments to handle and condition coherent ultrafast pulses in the extreme-ultraviolet is discussed. The main application of such instruments is the monochromatization of high-order laser harmonics and free-electron-laser ...

Interference suppression techniques for OPM-based MEG: Opportunities and challenges

NeuroImage, 2022
One of the primary technical challenges facing magnetoencephalography (MEG) is that the magnitude of neuromagnetic fields is several orders of magnitude lower than interfering signals.

Analysis of OPM potentials for multiplet states of 3d transition metal atoms

, 2004
We apply the optimized effective potential method (OPM) to the multiplet energies of the 3d$^n$ transition metal atoms, where the orbital dependence of the energy functional with respect to orbital wave function is the single-configuration HF form.

Ellipticity and Deviations from Orthogonality in the Polarization Modes of PSR B0329+54 [PDF]

, 2004
We report on an analysis of the polarization of single pulses of PSR B0329+54 at 328 MHz. We find that the distribution of polarization orientations in the central component diverges strongly from the standard picture of orthogonal polarization modes ...

Source-level performance of triaxial and uniaxial-radial OPM-MEG

NeuroImage
Magnetoencephalography (MEG) based on optically pumped magnetometers (OPM) provides a new means for detecting human brain activities. Compared to conventional SQUID-MEG, OPM-MEG offers significant advantages, including the wearability, flexibility in ...
