A decidable weakening of Compass Logic based on cone-shaped cardinal directions [PDF]

open access: yes, 2015
We introduce a modal logic, called Cone Logic, whose formulas describe properties of points in the plane and spatial relationships between them. Points are labelled by proposition letters and spatial relations are induced by the four cone-shaped cardinal

Enhanced Magnetization Switching Efficiency via Orbital‐Current‐Induced Torque in Ti/Ta (Pt)/CoFeB/MgO Structures

open access: yesAdvanced Functional Materials, EarlyView.
The orbital‐current‐induced torque is investigated as an efficient method for controlling magnetization direction. By introducing Ti as an orbital current source in Ti/Ta (or Pt)/CoFeB/MgO structures, the switching current is reduced by ∼25% compared to a conventional spin‐orbit torque structure of Ta/CoFeB/MgO.

The effects of time-variance on impedance measurements: examples of a corroding electrode and a battery cell

open access: yesJournal of Electrochemical Science and Engineering, 2020
When performing electrochemical impedance spectroscopy (EIS) measurements on a system, we must make sure it fulfills certain conditions. One of them is that it should be stationary that is to say, steady-state and time-invariant. Commonly studied systems

On Affine Logic and {\L}ukasiewicz Logic [PDF]

open access: yes, 2014
The multi-valued logic of {\L}ukasiewicz is a substructural logic that has been widely studied and has many interesting properties. It is classical, in the sense that it admits the axiom schema of double negation, [DNE]. However, our understanding of {\L}

Dynamic Networks via Polymerizable Deep Eutectic Monomers for Uniform Li+ Transport at Interfaces in Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The PDEM‐based SIGPE provides a dynamic nanophase from Li+‐bridged molecular self‐association, enhancing electrochemical stability and facilitating uniform Li+ ion flux at the interface. This unique solvation structure results in a hetero species‐driven inorganic‐rich SEI and long‐term cycle stability, suggesting that a PFAS‐free Li+‐containing monomer

Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors

open access: yesAdvanced Functional Materials, EarlyView.
2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...

Material-Device-Circuit Co-Design of 2-D Materials-Based Lateral Tunnel FETs

open access: yesIEEE Journal of the Electron Devices Society, 2018
In this paper, the 2-D materials-based lateral TFETs are holistically assessed by co-optimizing the material parameters, device designs, and digital circuit figure-of-merits, e.g., energy consumption and delay.

Necessity in the Thought of Avicenna [PDF]

open access: yesحکمت و فلسفه, 2018
To Avicenna, the relation between the subject and the predicate is of three kinds: possibility, necessity, and impossibility. Impossibility is the same as necessary non-existence. The word ‘modal’ in modal logic refers to these three.

Simulation Studies of Nanomagnet-Based Architecture

open access: yes, 2008
We report a simulation study on interacting ensembles of Co nanomagnets that can perform basic logic operations and propagate logic signals, where the state variable is the magnetization direction.

The Logic of Logic Programming

open access: yes, 2023
Our position is that logic programming is not programming in the Horn clause sublogic of classical logic, but programming in a logic of (inductive) definitions. Thus, the similarity between prototypical Prolog programs (e.g., member, append, ...) and how inductive definitions are expressed in mathematical text, is not coincidental but essential.
