ITERATING SYMMETRIC EXTENSIONS [PDF]

open access: yesThe Journal of Symbolic Logic, 2019
AbstractThe notion of a symmetric extension extends the usual notion of forcing by identifying a particular class of names which forms an intermediate model of $ZF$ between the ground model and the generic extension, and often the axiom of choice fails in these models. Symmetric extensions are generally used to prove choiceless consistency results.

Districting in last‐mile delivery with stochastic customers

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 3, Page 1636-1655, May 2026.
Abstract Due to the peculiarities of city streets, last‐mile logistics is typically organized using territory‐based routing approaches, which divide the city into a set of districts and assign drivers to deliver in one or more of them. This allows drivers to develop a deep understanding of the characteristics of each district, and clients benefit from ...

Space Correlation Constrained Physics Informed Neural Network for Seismic Tomography

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Physics‐informed neural networks (PINNs) integrate physical constraints with neural architectures and leverage their nonlinear fitting capabilities to solve complex inverse problems. Tomography serves as a classic example, aiming to reconstruct subsurface velocity models to improve seismic exploration.

UITOTO: a software for generating molecular diagnoses for species descriptions

open access: yesCladistics, Volume 42, Issue 2, Page 193-205, April 2026.
Abstract Millions of species remain undescribed, and each eventually will require a species description with a diagnosis. Yet, we lack software that can derive state‐specific and contrastive molecular diagnoses and allows the user to validate them based on all available sequences for the taxon under study. Here we introduce UITOTO, which addresses this

The superconducting proposal for the CS magnet system of FAST: a preliminary analysis of the heat load due to AC losses

open access: yes, 2011
FAST (Fusion Advanced Studies Torus), the Italian proposal of a Satellite Facility to ITER, is a compact tokamak (R$_0$ = 1.82 m, a = 0.64 m, triangularity $\delta$ = 0.4) able to investigate non-linear dynamics effects of $\alpha$-particle behavior in ...

Randomised, Double‐Blinded, Placebo‐Controlled Challenge Test With Single Food Items in Dogs With Atopic Dermatitis and Adverse Food Reactions

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 247-256, April 2026.
ABSTRACT Background Identification of offending foods in dogs with adverse food reactions is usually based on “deterioration” during open food challenges. Objectives To examine the placebo effect during double‐blinded, placebo‐controlled food challenges using a predefined set of criteria for relapse.

Accelerating Conjugate Gradient Solvers for Homogenization Problems With Unitary Neural Operators

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.
ABSTRACT Rapid and reliable solvers for parametric partial differential equations (PDEs) are needed in many scientific and engineering disciplines. For example, there is a growing demand for composites and architected materials with heterogeneous microstructures.
