Topology in Biological Piezoelectric Materials
Advanced Materials, EarlyView.This review summarizes the topological structures in biological piezoelectric materials, covering morphology evolution, spatial arrangement, and biomimetic strategies. These topologies modulate structure‐property relationships across multiple scales, enabling performance enhancement and multifunctional integration.

Determination of the number of texture segments using wavelets
Electronic Journal of Differential Equations, 2001 This paper presents a robust method of determining the number of texture segments in an image. We take an $N imes N$ image and decompose it into $n imes n$ blocks.

AI‐Driven Defect Engineering for Advanced Thermoelectric Materials
Advanced Materials, EarlyView.This review presents how AI accelerates the design of defect‐tuned thermoelectric materials. By integrating machine learning with high‐throughput data and physics‐informed representations, it enables efficient prediction of thermoelectric performance from complex defect landscapes.

Dualities of deformed N = 2 $$ \mathcal{N}=2 $$ SCFTs from link monodromy on D3-brane states
Journal of High Energy Physics, 2017 We study D3-brane theories that are dually described as deformations of two different N = 2 $$ \mathcal{N}=2 $$ superconformal theories with massless monopoles and dyons. These arise at the self-intersection of a seven-brane in F-theory, which cuts out a

Note on the Labelled tree graphs
Journal of High Energy Physics, 2020 In the CHY-frame for the tree-level amplitudes, the bi-adjoint scalar theory has played a fundamental role because it gives the on-shell Feynman diagrams for all other theories.

Half-hypermultiplets and incomplete/complete resolutions in F-theory
Journal of High Energy Physics, 2020 We consider resolutions of codimension-two enhanced singularities from SO(12) to E 7 and from E 7 to E 8 in six-dimensional F-theory, where a half-hypermultiplet arises for generic complex structures achieving them. The exceptional fibers at the enhanced

Lectures on Graded Differential Algebras and Noncommutative Geometry [PDF]
, 2001 These notes contain a survey of some aspects of the theory of graded differential algebras and of noncommutative differential calculi as well as of some applications connected with physics. They also give a description of several new developments.

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.

Root bundles and towards exact matter spectra of F-theory MSSMs
Journal of High Energy Physics, 2021 Motivated by the appearance of fractional powers of line bundles in studies of vector-like spectra in 4d F-theory compactifications, we analyze the structure and origin of these bundles.
