Small Science, Volume 5, Issue 12, December 2025.Self‐assembled vertically aligned nanocomposite (VAN) BTO: (Au‐Co‐Pd) and BTO: (Au‐Pd) VAN thin films are grown using a simplified oxide‐metal strips deposition method in pulsed laser deposition. The hybrid VAN films exhibit tunable localized plasmonic surface resonance and hyperbolic dispersion characteristics in the visible to near‐infrared ...

Acoustic Wavefront Shaping Using Ultrahigh Phase Resolution Metamaterial
Advanced Materials Technologies, Volume 10, Issue 22, November 19, 2025.A Bilateral Symmetrical T‐shaped (BST) acoustic metamaterial unit cell capable of achieving a high phase resolution of π/36 radians at 8000 Hz is introduced. The approach enables tunable wavefront control through simple rotational adjustment of BST, which offers an alternative to the conventional complex metamaterials unit cell design and a way for ...

THE HYPERBOLOID OF REVOLUTION OF ONE NAPPE A RULED SURFACE GENERATING CONICS
Journal of Industrial Design and Engineering Graphics, 2013 The paper intends to underline the property of the hyperboloid of revolution of one nappe to generate on its surface, when it is cut by a plane, the three known conics (ellipse, hyperbola and parabola).Cutting this surface by a plane, we find the ...

Ultraspinning limits and rotating hyperboloid membranes
Nuclear Physics B, 2016 We apply the hyperboloid membrane limit to the general Kerr-AdS metrics and their recently studied super-entropic cousins and obtain a new class of rotating black holes, for which the rotational parameters in multiple directions attain their maximal ...

Delay Discounting and Teacher Decision‐Making of Behavioral Interventions
Behavioral Interventions, Volume 40, Issue 4, November 2025.ABSTRACT This paper presents two studies that used delay discounting to understand how teachers of students who engage in challenging behavior discount delays in behavioral treatment outcomes. In Experiment 1, the authors administered the monetary choice questionnaire (MCQ) to assess discounting of monetary rewards and a treatment choice questionnaire (

Dirac fermions on a disclinated flexible surface
, 2010 A self-consisting gauge-theory approach to describe Dirac fermions on flexible surfaces with a disclination is formulated. The elastic surfaces are considered as embeddings into R^3 and a disclination is incorporated through a topologically nontrivial ...

Harmonic analysis on hyperboloids
Journal of Functional Analysis, 1973 AbstractThe regular representation of O(n, N) acting on L2(O(n, N)O(n, N − 1)) is decomposed into a direct integral of irreducible representations. The homogeneous space O(n, N)O(n, N − 1) is realized as the Hyperboloid H = {(x, t) ϵ Rn + N : ¦ t ¦2 − ¦ x ¦2 = 1}.

Superquadric Motion and Superquadric Hyperbolic Split Quaternion Algebra Via Gielis Formula
Mathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 15035-15048, 15 November 2025.ABSTRACT Superquadrics are one of the most suitable geometric tools for modeling many complex shapes in nature. It is possible to model many objects, human figures, and living creatures in nature in a suitable way by means of superquadrics. On the other hand, quaternions are useful in mathematics, especially for computations involving three‐dimensional
