A five-valued logic and a system

open access: yesJournal of Computer Science and Technology, 2004
The present article introduces a five-valued logic and a deductive system. Here, the logic presented is a relevant fragment of the @-logic, which is also a space-time logic. These five values correspond to the following semantics: unknown, possibly known

Symmetry Breaking in Chemical Systems: Engineering Complexity Through Self‐Organization and Marangoni Flows

open access: yesAdvanced Science, EarlyView.
We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

Influence of Anode Reactivity and Chemical Crossover on the Formation of Cathode‐Electrolyte Interphase in High‐Nickel Layered Oxide Cathodes

open access: yesAdvanced Energy Materials, EarlyView.
Full cells pairing NMC811 cathodes with graphite, prelithiated SiOx, and Li‐metal anodes are cycled at 45 °C to investigate how anode reactivity influences the cathode surface composition. Electrochemical and surface characterization techniques reveal that anodes with unstable solid‐electrolyte interphases increase cathode degradation through cathode ...

A \textsf{C++} reasoner for the description logic $\shdlssx$ (Extended Version)

open access: yes, 2018
We present an ongoing implementation of a \ke\space based reasoner for a decidable fragment of stratified elementary set theory expressing the description logic $\dlssx$ (shortly $\shdlssx$).

Molecular Engineering of Hybrid Electrolytes for Aqueous Zinc Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A molecularly engineered hybrid electrolyte enhances Zn (de)plating reversibility in aqueous zinc‐ion batteries (AZIBs). Fluorine‐functionalized triethyl phosphate tailors the solvation environment to modulate the desolvation kinetics and suppress water‐induced parasitic reactions.

Weak MSO: Automata and Expressiveness Modulo Bisimilarity

open access: yes, 2014
We prove that the bisimulation-invariant fragment of weak monadic second-order logic (WMSO) is equivalent to the fragment of the modal $\mu$-calculus where the application of the least fixpoint operator $\mu p.\varphi$ is restricted to formulas $\varphi$

Foreign labor, peer‐networking and agricultural efficiency in the Italian dairy sector

open access: yesAgribusiness, EarlyView.
Abstract While the presence of immigrants in the agricultural sector is widely acknowledged, the empirical evidence on its economic consequences is lacking, especially from a microeconomic perspective. Using the Farm Accountancy Data Network panel data for Italian dairy farms in the period 2008–2018, the present study investigates the relationship ...

The decidability of a fragment of BB′IW-logic

open access: yesTheoretical Computer Science, 2004
AbstractDespite its simple formulation, the decidability of the logic BB′IW has remained an open problem. We present here a decision procedure for a fragment of it, called the arity-1 formulas.The decidability proof is based on a representation of formulas called formula-trees, which is coupled with a proof method that computes long normal λ-terms that
