From transporter to motor: Evolutionary and structural insights into the emergence of prestin's area‐motor activity in mammals

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Prestin, a member of the SLC26A family, is essential for the electromotility of mammalian outer hair cells, converting voltage changes into mechanical work. In contrast, nonmammalian orthologues function as anion transporters. To investigate the molecular and structural basis of this functional divergence, we performed ancestral sequence ...

MAVISp: A modular structure‐based framework for protein variant effects

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract The role of genomic variants in disease has expanded significantly with the advent of advanced sequencing techniques. The rapid increase in identified genomic variants has led to many variants being classified as Variants of Uncertain Significance or as having conflicting evidence, posing challenges for their interpretation and ...

A Bibliometric Review of the INCOSE's Model‐Based Systems Engineering Roadmap

open access: yesSystems Engineering, Volume 29, Issue 3, Page 567-588, May 2026.
ABSTRACT Over the past decade, model‐based systems engineering (MBSE) has gained attention as an approach for managing system complexity, offering a shift from a document‐based to a model‐based approach. The International Council on Systems Engineering (INCOSE) sparked increasing interest when it introduced MBSE and its roadmap as part of its systems ...

Operator projection method applied to the single-particle Green's function in the Hubbard model

open access: yes, 2001
A new non-perturbative framework for many-body correlated systems is formulated by extending the operator projection method (OPM). This method offers a systematic expansion which enables us to project into the low-energy structure after extracting the ...

A Unified Requirements‐Architecture System Model—Development and Empirical Evaluation

open access: yesSystems Engineering, Volume 29, Issue 3, Page 511-523, May 2026.
ABSTRACT Moving systems engineering's center of gravity from text documents to digital models, model‐based system engineering (MBSE) facilitates collaboration, reduces errors, and improves system understanding, but systems engineers often face challenges when they start working with MBSE, as they need to consider and model textual requirements as a ...

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...
