An allocation rule for connection scheduling problems

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 2, Page 892-925, March 2026.
Abstract This paper studies so‐called connection scheduling problems, a type of interactive operations research problem. A connection scheduling problem combines aspects from the minimum cost spanning tree and sequencing problems. Given a graph, we aim to first establish a connection order on the players such that the total cost of connecting them to a

A Novel Peak‐Shape Aware Approach for Mass Alignment in Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 4, 28 February 2026.
ABSTRACT Rationale In mass spectrometry measurements, mass shifts may be inadvertently introduced due to instrumental drift and calibration inaccuracies, potentially compromising the accuracy of subsequent data analysis. This work presents a novel, label‐free algorithm to improve relative mass alignment between mass spectra.

Guanidinium Like‐Charge Ion Pairing and Oligoarginine Aggregation in Water by Nuclear Magnetic Resonance, Cryo‐Electron Microscopy, and Molecular Dynamics

open access: yesAggregate, Volume 7, Issue 2, February 2026.
This study shows that guanidinium cations weakly attract one another in water and form like‐charge contact ion pairs. From NMR, we determine the free energy of ion‐pair formation to be ≈${\approx }$ –0.5 kJ mol−1${\rm mol}^{-1}$, consistent with all‐atom MD simulations and DFT calculations.
