Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices
Advanced Materials Interfaces, EarlyView.This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

The projectable hull of an archimedean $ell$-group with weak unit [PDF]
Categories and General Algebraic Structures with Applications, 2017 The much-studied projectable hull of an $ell$-group $Gleq pG$ is an essential extension, so that, in the case that $G$ is archimedean with weak unit, ``$Gin {bf W}$", we have for the Yosida representation spaces a ``covering map" $YG leftarrow YpG$.

Automatic Deduction in Dynamic Geometry using Sage [PDF]
Electronic Proceedings in Theoretical Computer Science, 2012 We present a symbolic tool that provides robust algebraic methods to handle automatic deduction tasks for a dynamic geometry construction. The main prototype has been developed as two different worksheets for the open source computer algebra system Sage,

Advanced Optical Materials, EarlyView.Theoretical lessons are key for molecules presenting an inverted singlet‐triplet excited state (e.g. S1 and T1) energy difference. This perspective provides a snapshot of the role played by calculations in last years, not only to anticipate experimental findings but also for driving high‐throughput virtual screenings, as well as the main challenge to ...

Cleaning Data With Selection Rules
IEEE Access, 2022 In this paper, we propose and study a type of tuple-level constraint that arises from the selection operator $\sigma $ of relational algebra and that closely resembles the concepts of tuple-level denial constraints.

Advanced Theory and Simulations, EarlyView.FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,

On the universal coverings of algebraic surfaces [PDF]
Annales Scientifiques de l’École Normale Supérieure, 1998 Abstract In this paper we use some recent developments in Nonabelian Hodge theory to study the existence of holomorphic functions on the universal coverings of algebraic surfaces. In particular we prove that if the fundamental group of an algebraic surface is reductive then its universal covering is holomorphically convex.

Advanced Theory and Simulations, EarlyView.Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude

On the Hilbert series of vertex cover algebras of Cohen-Macaulay bipartite graphs
Le Matematiche, 2010 We study the Hilbert function and the Hilbert series of the vertex cover algebra A(G), where G is a Cohen-Macaulay bipartite graph.

Path Transmissibility Analysis Considering Two Types of Correlations in Hydropower Stations
Journal of Applied Mathematics, 2013 A new vibration model is built by introducing the head-cover vibration transfer path based on a previous analysis of the vertical vibration model for hydropower station units and powerhouses.
