Perturbative analysis of gauged matrix models [PDF]

open access: yes, 2002
We analyze perturbative aspects of gauged matrix models, including those where classically the gauge symmetry is partially broken. Ghost fields play a crucial role in the Feynman rules for these vacua.

Application Of Rating Scale Model In Conversion Of Rating Scales' Points To The Form Of Triangular Fuzzy Numbers

open access: yesFolia Oeconomica Stetinensia, 2014
A new application of fuzzy sets theory in social and economic research is a fuzzy measurement of respondents' opinions. In the subject literature fuzzy rating scales or fuzzy conversion scales are being applied.

Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

open access: yesAdvanced Materials, Volume 38, Issue 26, 8 May 2026.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).

Search For Dissimilarity Factors For Nominally Indiscernible Facilities

open access: yesReal Estate Management and Valuation, 2015
The similarity between premises, statutorily defined as the comparability of the compiled objects, is, in practice, identified by the statement of identity or the proximity of evaluation of the selected features describing the complied objects ...

Load‐Bearing Characteristics of SLA‐Fabricated Octahedral Porous Structures

open access: yesStrain, Volume 62, Issue 2, April 2026.
A combined experimental–numerical framework was developed to evaluate SLA–fabricated octahedral and pillar–reinforced lattice structures under compression, shear, and torsion. Small increases in infill density produced nonlinear gains in stiffness and strength, reaching a 255% rise in elastic modulus at low porosity. Pillar reinforcement enhanced shear

Roll‐to‐Roll Mechanical Exfoliation for Large‐Area van der Waals Films with Preserved Crystallographic Alignment

open access: yesAdvanced Functional Materials, Volume 36, Issue 25, 26 March 2026.
A roll‐to‐roll exfoliation method is demonstrated that preserves the crystallographic alignment of anisotropic 2D materials over large areas, enabling scalable fabrication of directional electronic and optoelectronic devices. Abstract Anisotropic 2D materials such as black phosphorus (BP), GeS or CrSBr, exhibit direction‐dependent optical and ...

Review of Memristors for In‐Memory Computing and Spiking Neural Networks

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Memristors uniquely enable energy‐efficient, brain‐inspired computing by acting as both memory and synaptic elements. This review highlights their physical mechanisms, integration in crossbar arrays, and role in spiking neural networks. Key challenges, including variability, relaxation, and stochastic switching, are discussed, alongside emerging ...
