Dam-Breach hydrology of the Johnstown flood of 1889–challenging the findings of the 1891 investigation report

Heliyon, 2016
In 1891 a report was published by an ASCE committee to investigate the cause of the Johnstown flood of 1889. They concluded that changes made to the dam by the South Fork Fishing and Hunting Club did not cause the disaster because the embankment would ...

Origin of life: β‐sheet amyloid conformers as the primordial functional polymers on the early Earth and their role in the emergence of complex dynamic networks

FEBS Letters, EarlyView.
The amyloid world hypothesis of the origin‐of‐life posits that the first functional polymers on the early Earth were structurally stable cross‐β‐sheet‐based peptide amyloids capable of Darwinian‐like evolution. Peptide amyloids display self‐replication and information transfer, as well as catalytic, adaptive, and evolutive properties.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

FEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Opportunities for Characterizing Geological Flows Using Magnetic Resonance Imaging

iScience, 2020
Summary: Geological flows—from mudslides to volcanic eruptions—are often opaque and consist of multiple interacting phases. Scaled laboratory geological experiments using analog materials have often been limited to optical imaging of flow exteriors or ex

Inspecting map compilation in earth sciences for better communication

Hungarian Geographical Bulletin, 2021
The use of thematic cartography in earth sciences is a frequent task for researchers when publishing. When creating a map, researchers intend to communicate important spatial information that enhances, supplements or replaces textual content.
