Data from a Geophysical Survey at Tophams Solar Farm, North Hertfordshire 2021

open access: yes, 2023
This collection comprises data from a geophysical survey undertaken by Magnitude Surveys Ltd over a c. 58.25ha area of land at Tophams Solar Farm between May and June 2021. Archaeological activity was identified across the survey area.

Correcting exponentiality test for binned earthquake magnitudes

open access: yesSeismica
Above the magnitude of completeness - the minimum threshold for which a 100% detection rate is assumed - earthquake magnitudes are typically modeled as a continuous exponential distribution.

Magnitude correlations in a self-similar aftershock rates model of seismicity [PDF]

open access: yesNonlinear Processes in Geophysics, 2020
Crucial to the development of earthquake forecasting schemes is the manifestation of spatiotemporal correlations between earthquakes as highlighted, for example, by the notion of aftershocks.

The complete universe: probing magnitude completeness and evolution in galaxy redshift surveys [PDF]

open access: yes, 2009
The work in this thesis charts the revival and development of research that tests some of the core fundamental assumptions that characterise the study of magnitude-redshift surveys for the estimation of galaxy luminosity functions (LF).

Possible Problems of Evaluation of Spatial-Temporal Features of Earthquake Catalog Representativity: Case Study for the Kamchatka Catalog of Geophysical Survey of RAS

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019
The completeness of the catalog, understood as the magnitude threshold from which earthquakes are recorded without gaps, is usually determined by the linear part of the magnitude-frequency relationship in accordance with the Gutenberg-Richter law.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The Matrix Completion Method for Phase Retrieval from Fractional Fourier Transform Magnitudes [PDF]

open access: yesMathematical Problems in Engineering, 2016
Inspired by the implementation of the fractional Fourier transform (FRFT) and its applications in optics, we address the problem of reconstructing a signal from its several FRFT magnitudes (or intensities). The matrix completion method is adopted here.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

On stochastic completeness of weighted graphs [PDF]

open access: yes, 2011
Huang X. On stochastic completeness of weighted graphs. Bielefeld: Universität; 2011.In this thesis we are concerned with the long time behavior of continuous time random walks on infinite graphs. The following three related problems are considered.

A test on methods for Mc estimation and spatial-temporal distribution of b-value in the eastern Tibetan Plateau

open access: yesFrontiers in Earth Science
Seismic b-value is one of the most important parameters for seismological research and seismic hazards assessment, while the accuracy of the b-value largely depended on the completeness of seismic catalog.
