MapsTorch: automatic differentiation for X‐ray fluorescence data analysis

Journal of Synchrotron Radiation, EarlyView.
MapsTorch is a new open‐source package that enables automatic differentiation for X‐ray fluorescence (XRF). The robust performance of MapsTorch makes it possible to automate steps that are usually manual in XRF analysis, including initial spectrum fitting and elemental intensity refinement, and therefore can support automated, high‐throughput workflows

Leopard‐EM: an extensible 2D template‐matching package to accelerate in situ structural biology

Acta Crystallographica Section D, EarlyView.
In situ cryo‐EM coupled with 2D template matching (2DTM) holds the potential to visualize the cellular structureome in context, but further developments are required to make this a reality. We describe Leopard‐EM (Location and orientation of particles found using two‐dimensional tEmplate Matching), an extensible Python package for 2DTM to accelerate in

Strategies for mitigating radiation damage and improving data completeness in 3D electron diffraction of protein crystals

Acta Crystallographica Section D, EarlyView.
This work demonstrates that multi‐position data acquisition mitigates radiation damage in electron diffraction of three‐dimensional protein crystals and that merging data from selected crystals in distinct orientations enhances completeness. Application of the two approaches enables high‐quality structural models to be obtained from limited or ...

Fuel Prices and Ambient Air Pollution: A Study of Sydney*

Economic Record, EarlyView.
This paper explores the short‐run influence of road transport fuel prices on ambient air pollution over the period 2004–2023 for the case of Sydney, Australia. Using daily data from nine air quality monitoring stations, we find negative effects of fuel prices on ambient concentrations of several key pollutants including ozone, nitrogen dioxide and ...

The public agglomeration effect: Urban–rural divisions in government efficiency and political preferences

American Journal of Political Science, EarlyView.
Abstract Why and when do cities vote for the left? The emergence of the urban–rural divide in the United States in the 1930s is inconsistent with canonical theories of cleavages. This paper introduces an explanation: agglomeration effects. The provision of government services is more efficient in urban environments because of nonrivalries, economies of

An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems

International Economic Review, EarlyView.
ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.
