Bifunctional Electrocatalysts in Rechargeable Lithium‐Gas Batteries: Material Evolution and Mechanistic Insights from Metal‐Free Carbons to Carbon‐Supported Single‐Atom Sites

open access: yesSmall, EarlyView.
This review charts the material evolution of bifunctional electrocatalysts for rechargeable lithium‐gas batteries. It highlights the journey from heteroatom‐doped, metal‐free carbon architectures to precision‐engineered carbon‐supported single‐atom sites. The discussion focuses on mechanistic insights into how these catalysts govern reversible O2, CO2,

Classical logic and its rivals [PDF]

open access: yes, 2013
Classical logic and a given nonclassical logic are, by definition, incompatible in some sense. In some cases, this incompatibility is innocuous. In other cases, the nonclassical logic is incompatible with classical logic on a fundamental level, such that

Quantifiers for a Modal Future

open access: yesPhilosophical Perspectives, EarlyView.
ABSTRACT Future auxiliaries present a challenge to the classical analysis of modal expressions as existential or universal quantifiers over a contextually provided set of possible worlds: these expressions come with a distinct modal flavor, but their interaction with negation and the fact that future judgments come in degrees of confidence is ...

Mechanical transistors for logic-with-memory computing

open access: yes, 2023
As a potential revolutionary topic in future information processing, mechanical computing has gained tremendous attention for replacing or supplementing conventional electronics vulnerable to power outages, security attacks, and harsh environments ...

Peirce on Abduction and Diagrams in Mathematical Reasoning [PDF]

open access: yes, 2021
Questions regarding the nature and acquisition of mathematical knowledge are perhaps as old as mathematical thinking itself, while fundamental issues of mathematical ontology and epistemology have direct bearing on mathematical cognition.

These degrees go to eleven: fuzzy logics and gradable predicates

open access: yes, 2022
In the literature on vagueness one finds two very different kinds of degree theory. The dominant kind of account of gradable adjectives in formal semantics and linguistics is built on an underlying framework involving bivalence and classical logic: its ...

Verbal Metadisputes

open access: yesPhilosophy and Phenomenological Research, EarlyView.
ABSTRACT Many philosophical disputes have become so intractable that philosophers question whether there is a fact of the matter as to which side is right or whether these disputes are entirely verbal. Yet these “metadisputes” have also become intractable. This raises the question: Could they, too, be verbal? What would that even mean? Using tools from

Approximate reasoning, logics for self-reference, and the use of nonclassical logics in systems modeling

open access: yes, 1981
This work advances the use of nonclassical logics for developing qualitative models of real-world systems. Abstract mathematics is qualitative inasmuch as it relegates numerical considerations to the background and focuses explicitly on topological ...

Uncertainty Quantification of Analytical Solutions for the Nonlinear Space and Time Fractional Order ϕ4$$ {\phi}^4 $$ Equation Under Fuzziness

open access: yesEngineering Reports, Volume 8, Issue 7, July 2026.
Analytical fuzzy soliton solutions of a modified space–time fractional ϕ4$$ {\phi}^4 $$ model are derived using EHFM, capturing memory effects and uncertainty. Results reveal diverse wave structures and show how fractional order and fuzziness significantly influence soliton amplitude, localization, and propagation, with heightened sensitivity near the ...

On the way to a wider model theory: completeness theorems for first-order logics of formal inconsistency

open access: yes, 2015
sem informaçãoThis paper investigates the question of characterizing first-order LFIs (logics of formal inconsistency) by means of two-valued semantics.
