Exact Solutions for the Moving Firefighter Problem on Trees
Networks, Volume 88, Issue 1, Page 42-58, July 2026.ABSTRACT The moving firefighter problem (MFP) is a more realistic variant of the classic firefighter problem (FP), where firefighters require time for both travel and defense. Unfortunately, the only known exact solution for the MFP does not scale. In this paper, we establish that the MFP is NP‐complete on trees of maximum degree three and present four

Strategic Management Journal, Volume 47, Issue 7, Page 1840-1877, July 2026.Abstract Research Summary We extend ecosystem theory to cases in which platforms are complementors to each other: inter‐platform ecosystems. Analyzing web traffic data on 241 European platforms, we identify and characterize demand‐side inter‐platform ecosystems, and propose a theory of why they emerge.

Red‐Pi: A Low‐Cost Red Teaming Platform for Water Infrastructure Security Assessment
SECURITY AND PRIVACY, Volume 9, Issue 4, July/August 2026.ABSTRACT The water and wastewater sector faces growing cyber threats due to rapid digitalization and the use of IoT‐based control systems. Many utilities manage essential services that affect public health and the environment but do not have enough cybersecurity staff and cannot afford regular security tests.

Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data
Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Weather satellite data contains a wealth of information well beyond its application to meteorology. The GOES weather satellite Geostationary Lightning Mapper instruments detect millions of lightning strikes per day. Within these “haystacks” of lightning are a handful of “needles” of bolides (aka bright fireballs, or exploding meteors). We have

Scotty: lattice coincidences for macromolecular crystallographic phasing
Acta Crystallographica Section D, Volume 82, Issue 7, Page 813-823, July 2026.Scotty is a tool that leverages Niggli‐cell matches to identify similar crystallographic lattices and perform phasing with difference Fourier methods.When a macromolecular crystal lattice targeted for study is closely related to a previously studied crystal lattice, phasing the target crystal by difference (fast‐)Fourier transform (DFFT) methods is ...

Acta Crystallographica Section D, Volume 82, Issue 7, Page 751-760, July 2026.Monte Carlo simulations of neutron protein diffraction experiments provide useful data that models neutrons interacting with instrument components, as well as the crystal diffraction itself. These data can be applied to instrument development, such as the commissioning of the NMX Macromolecular Diffractometer at ESS.Monte Carlo neutron ray‐tracing ...

Defining the geographical level of competition: a taxonomy of industry tradability
Economica, Volume 93, Issue 371, Page 962-991, July 2026.Abstract The paper develops a taxonomy of industry tradability to define the geographical level at which competition takes place. First, it creates a novel dataset that combines production and international trade data for both goods and services industries, defined at a detailed (3‐digit) level of industry aggregation for 15 European countries.

How Precise Is Predictive Coding for Things We Hear? Mismatch Negativity With Shepard Tones
European Journal of Neuroscience, Volume 64, Issue 1, July 2026.MMN amplitudes to unpredictable tones in a discrete Shepard scale were more negative the farther the unpredictable tones were from the predicted note and more negative for tones that were less than the expected note. We conclude that the predictive model for a discrete Shepard scale has a sensitivity to tones less than one third of a semitone and is ...
