Statistical paleoclimate reconstructions via Markov random fields

, 2015
Understanding centennial scale climate variability requires data sets that are accurate, long, continuous and of broad spatial coverage. Since instrumental measurements are generally only available after 1850, temperature fields must be reconstructed ...

Kernel Interpolation for Scalable Structured Gaussian Processes (KISS-GP) [PDF]

, 2015
We introduce a new structured kernel interpolation (SKI) framework, which generalises and unifies inducing point methods for scalable Gaussian processes (GPs).

A Novel Generic Framework for Track Fitting in Complex Detector Systems

, 2010
This paper presents a novel framework for track fitting which is usable in a wide range of experiments, independent of the specific event topology, detector setup, or magnetic field arrangement.

Combining Full-Shape and BAO Analyses of Galaxy Power Spectra: A 1.6% CMB-independent constraint on H0

, 2020
We present cosmological constraints from a joint analysis of the pre- and post-reconstruction galaxy power spectrum multipoles from the final data release of the Baryon Oscillation Spectroscopic Survey (BOSS).

Robust DOA estimation for two‐level nested arrays in unknown mutual coupling

Electronics Letters
Aiming at solving the problem that the capability of direction of arrival method for estimation of nested arrays decreases sharply under unknown mutual coupling, an iterative weighted low‐rank matrix reconstruction algorithm is proposed here.

Dynamic phasor measurement algorithm based on high-precision time synchronization

Frontiers in Signal Processing
Ensuring the swift and precise tracking of power system signal parameters, especially the frequency, is imperative for the secure and stable operation of power grids. In instances of faults within the distribution network, abrupt changes in frequency may

Efficient and Robust Adaptive Beamforming Based on Coprime Array Interpolation

Remote Sensing
Unlike uniform linear arrays (ULAs), coprime arrays require fewer physical sensors yet provide higher degrees of freedom (DOF) and larger array apertures.

Structural Variability from Noisy Tomographic Projections

, 2018
In cryo-electron microscopy, the 3D electric potentials of an ensemble of molecules are projected along arbitrary viewing directions to yield noisy 2D images.

Quantum state reconstruction of spectral field modes: homodyne and resonator detection schemes

, 2013
We revisit the problem of quantum state reconstruction of light beams from the photocurrent quantum noise. As is well-known, but often overlooked, two longitudinal field modes contribute to each spectral component of the photocurrent (sideband modes). We
