Market Insurance and Risk Pooling in U.S. Crop Insurance

open access: yesAgricultural Economics, Volume 57, Issue 2, March 2026.
ABSTRACT A common assumption is that multiple‐peril crop insurance markets suffer from market failures, thus justifying government intervention in the form of premium subsidies, operating allowances, and reinsurance agreements. One prominent rationale for intervention involves geographic correlation in agricultural production which leads to systemic ...

Phenomenal knowledge and phenomenal causality

open access: yesNoûs, Volume 60, Issue 1, Page 212-232, March 2026.
Abstract There has been extensive debate over whether we can have phenomenal knowledge in the case of epiphenomenalism. This article aims to bring that debate to a close. I first develop a refined causal account of knowledge—one that is modest enough to avoid various putative problems, yet sufficiently robust to undermine the epiphenomenalist position.

Unified Analytic Framework for Thickness‐Dependent Transport and Trap‐State Modulation in Ultrathin W:In2O3 Field‐Effect Transistors

open access: yesSmall Structures, Volume 7, Issue 2, February 2026.
We present a unified analytic framework linking subthreshold and above‐threshold conduction in oxide field‐effect transistors by decomposing the drain current into band transport, tail‐state percolation, and interface‐trap diffusion components. Parameter correlation and identifiability analyses enable robust extraction of physical metrics, yielding ...

Do Busy Bees Still Make Honey? Examining the Impact of Non‐CEO Executives’ Outside Roles on Firm Performance

open access: yesFinancial Review, Volume 61, Issue 1, Page 229-260, February 2026.
ABSTRACT We examine how non‐CEO executives (NCEs) serving on outside boards affect their focal firm performance. Firms with such NCEs exhibit lower return on asset (ROA) and profit margins than those without. These effects begin after board service starts, are not explained by busy boards or CEOs, and persist at least a year.

Strategic Flip‐Flopping in Political Competition

open access: yesInternational Economic Review, Volume 67, Issue 1, Page 79-96, February 2026.
ABSTRACT We study candidates' position adjustments in response to information about voters' preferences. Repositioning allows candidates to move closer to the median voter, but it incurs financial and electoral costs. In a subgame‐perfect equilibrium, candidates diverge from the center ex ante if the costs of adjustment are sufficiently large.

Revisiting Chase Termination for Existential Rules and their Extension to Nonmonotonic Negation [PDF]

open access: yes, 2014
Existential rules have been proposed for representing ontological knowledge, specifically in the context of Ontology- Based Data Access. Entailment with existential rules is undecidable. We focus in this paper on conditions that ensure the termination of

Is Computing with Light All You Need? A Perspective on Codesign for Optical Artificial Intelligence and Scientific Computing

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 1, January 2026.
This perspective article considers what computations optical computing can and should enable. Focusing upon free‐space optical computing, it argues that a codesign approach whereby materials, devices, architectures, and algorithms are simultaneously optimized is needed.

Randomized Hypergraph States and Their Entanglement Properties

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
Randomized hypergraph (RH) states are mixed states that extend the concept of randomized graph states to multi‐qubit hypergraphs subject to probabilistic gate imperfections. By modeling noisy multi‐qubit operations, this work reveals nonmonotonic behavior in bipartite and multipartite entanglement, derives analytical witnesses for specific hypergraph ...

Logical problems with nonmonotonicity

open access: yesLogic and Logical Philosophy, 2014
A few years ago, believing that human thinking is nonmonotonic, I tried to reconstruct a nonmonotonic reasoning by application of two monotonic procedures. I called them “step forward” and “step backward” (see [4]). The first procedure is just a consequence operation responsible for an extension of the set of beliefs.

Crystallographic‐Orientation‐Independent Field‐Free Deterministic Magnetization Switching in Perpendicularly Aligned WTe2/Fe3GeTe2/WTe2 Heterostructures

open access: yesSmall Structures, Volume 7, Issue 1, January 2026.
Field‐free magnetization switching is achieved in WTe2/Fe3GeTe2/WTe2 heterostructures by exploiting WTe2's strong charge‐to‐spin conversion. The switching behavior is independent of the crystallographic orientation of the pulse current, enabling robust operation in perpendicular and parallel configurations.
