Almost structural completeness; an algebraic approach [PDF]

open access: yes, 2014
A deductive system is structurally complete if its admissible inference rules are derivable. For several important systems, like modal logic S5, failure of structural completeness is caused only by the underivability of passive rules, i.e. rules that can

Algebraic structures of tropical mathematics

open access: yes, 2013
Tropical mathematics often is defined over an ordered cancellative monoid $\tM$, usually taken to be $(\RR, +)$ or $(\QQ, +)$. Although a rich theory has arisen from this viewpoint, cf.

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs

open access: yesAdvanced Engineering Materials, EarlyView.
This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable

Auxiliary Linear Problem, Difference Fay Identities and Dispersionless Limit of Pfaff-Toda Hierarchy

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
Recently the study of Fay-type identities revealed some new features of the DKP hierarchy (also known as ''the coupled KP hierarchy'' and ''the Pfaff lattice'').

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Normele de aplicare necesară – un concept în mişcare// The Overriding Mandatory Rules – an evolutive concept

open access: yesAnalele Ştiinţifice ale Universităţii "Al.I. Cuza" din Iaşi. Ştiinţe Juridice
The paper aims to point out and assess the mechanism of methodological transformation of the concept of conflict of laws. Within this mechanism, the conflict of laws does not pendulate anymore between the methodologies of multilateralism and ...

Twisted immanant and matrices with anticommuting entries

open access: yes, 2015
This article gives a new matrix function named "twisted immanant," which can be regarded as an analogue of the immanant. This is defined for each self-conjugate partition through a "twisted" analogue of the irreducible character of the symmetric group ...

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

open access: yesAdvanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

The (Un)canniness in Identities Among Biracial Taiwanese-Vietnamese Students

open access: yesSAGE Open
The identities of Taiwanese-Vietnamese students’ academic and social lives are not well-informed in the current body of research on international students in Vietnam, plus identities are often reported to be dynamic.

De-Anonymizing Users across Rating Datasets via Record Linkage and Quasi-Identifier Attacks

open access: yesData
The widespread availability of pseudonymized user datasets has enabled personalized recommendation systems. However, recent studies have shown that users can be de-anonymized by exploiting the uniqueness of their data patterns, raising significant ...
