Surpassing the Ratios Conjecture in the 1-level density of Dirichlet $L$-functions

open access: yes, 2014
We study the $1$-level density of low-lying zeros of Dirichlet $L$-functions in the family of all characters modulo $q$, with $Q/2 < q\leq Q$. For test functions whose Fourier transform is supported in $(-3/2, 3/2)$, we calculate this quantity beyond the

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Validation of artificial defects for Non-destructive testing measurements on a reference structure

open access: yesMATEC Web of Conferences, 2018
Non-destructive testing was established over the last decades as an important tool for assessing damages, material characterization and quality assurance in civil engineering. For example, Ground Penetrating Radar (GPR) can be used to scan large areas of

PTAA/TPBi Host–Guest Engineering Enables High‐Brightness Yellow Carbon Dot Based Light‐Emitting Diodes through Electron Confinement

open access: yesAdvanced Materials Interfaces, EarlyView.
In this study, CDs are incorporated into polymer or small‐molecule host materials to improve the morphology of EML films, balance charge transport and distribution, thereby enhancing charge recombination efficiency and device performance. Devices using PTTAA as the hole transport layer and TPBi as the host material exhibit the highest efficiency ...
