Monolithically 3D‐Printed Spectral‐Spatial Meta‐Authenticators

open access: yesAdvanced Materials, EarlyView.
A single height map printed in a low‐index resin by two‐photon lithography encodes multiple visible wavelengths in one metasurface without any polarization optics. A fabrication‐aware optimization folds the printable height levels into the design, so the device is printed as optimized.

Elliptic Curve Cryptography with Machine Learning

open access: yesCryptography
Elliptic Curve Cryptography (ECC) is a technology based on the arithmetic of elliptic curves used to build strong and efficient cryptosystems and infrastructures. Several ECC systems, such as the Diffie–Hellman key exchange and the Elliptic Curve Digital

Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials

open access: yesAdvanced Materials Interfaces, EarlyView.
Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...

K(_2) and L-series of elliptic curves over real quadratic fields [PDF]

open access: yes, 1995
This thesis examines the relationship between the L-series of an elliptic curve evaluated at s = 2 and the image of the regulator map when the curve is defined over a real quadratic field with narrow class number one, thus providing numerical evidence ...

Light‐Controlled Localized Delamination and Blistering of Azobenzene‐Containing Polymer Thin Films in an Aqueous Environment

open access: yesAdvanced Materials Interfaces, EarlyView.
When exposed to light of a defined wavelength, the photoisomerization of azobenzene chromophores leads to polymer reorientation, generating stresses that result in solvent‐facilitated localized delamination of the film from the substrate. Additionally, blisters that form spontaneously when exposed to an aqueous environment can be manipulated via ...

The Mordell-Weil theorem for elliptic curves over Q

open access: yes, 2023
reservedThe thesis will focus on the group of the rational points of an elliptic curve. The main theorem will be the Mordell-Weil theorem that asserts that this group is finitely generated.

A U‐shaped Microfluidic Platform for Culturing Vascularized Colorectal Cancer Spheroids Reveals Tumor–Endothelial Crosstalk and Invasion‐Associated Remodeling

open access: yesAdvanced Materials Technologies, EarlyView.
A closed U‐shaped microfluidic platform symmetrically embeds a single, size‐controlled HT29 colorectal cancer spheroid within a GFP‐HUVEC‐laden fibrin matrix. HT29 spheroids are associated with hyper‐branched endothelial network remodeling, while vascularized co‐culture is accompanied by anisotropic protrusive growth and EMT‐like marker changes in the ...
