Upper Bounds on the Minimum Size of Feedback Arc Set of Directed Multigraphs With Bounded Degree

open access: yesJournal of Graph Theory, Volume 112, Issue 4, Page 421-432, August 2026.
ABSTRACT An oriented multigraph is a directed multigraph without directed 2‐cycles. Let fas ( D ) denote the minimum size of a feedback arc set in an oriented multigraph D. In several papers, upper bounds for fas ( D ) were obtained for oriented multigraphs D with maximum degree upper‐bounded by a constant.

Weak, Strong and Mixed Extensions of Relations to Spaces of Ultrafilters

open access: yesMathematical Logic Quarterly, Volume 72, Issue 3, August 2026.
ABSTRACT The use of nonstandard methods to characterize properties of weak, strong and mixed extensions of congruences to ultrafilters has been the main topic of several recent papers, focused mostly on congruences and divisions. We show that similar methods can be used to extend these characterizations to arbitrary relations and their interplay.

Balance and Baselines: An Impossibility Theorem and an Axiomatisation of Additive Aggregation

open access: yesJournal of Multi-Criteria Decision Analysis, Volume 33, Issue 2, August 2026.
ABSTRACT A feature in many multicriteria problems is a preference for ‘balance’, understood as achieving a desired distribution (e.g., equality or target proportions) of resources across stakeholders or conceptual categories. This paper presents a normative exploration of the implications of balance preferences when baselines are uncertain or contested.

The Effect of Canagliflozin Dose on Renal and Cardiovascular Outcomes in Type 2 Diabetes and High Cardiovascular Risk

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 8, Page 7083-7093, August 2026.
ABSTRACT Introduction Pharmacokinetic data suggest a potential dose‐dependent effect of sodium–glucose co‐transporter‐2 (SGLT‐2) inhibitors on surrogate markers of efficacy, but the impact of SGLT‐2 inhibitor dose on renal and cardiovascular outcomes remains uncertain.

Semaglutide 25 mg Oral Versus Semaglutide 2.4 mg Injectable: An Indirect Treatment Comparison of Weight Loss Outcomes

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 8, Page 7237-7246, August 2026.
ABSTRACT Aims Semaglutide, a GLP‐1 receptor agonist, has demonstrated significant weight loss benefits for patients with overweight or obesity in both oral and subcutaneous (s.c.) formulations. Given comparable systemic exposure between formulations, an indirect treatment comparison (ITC) was conducted to confirm comparable efficacy.
