Dirichlet problem for a class of second order nonlinear elliptic equations

, 1995
Global existence and uniqueness of strong solutions to nonlinear elliptic partial differential equations are proved. The nonlinear operator under consideration is defined by Carath ́eodory’s functions, and it is elliptic in sense of Campanato. The main

Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Drift‐Corrected Monocular VIO and Perception‐Aware Planning for Autonomous Drone Racing

Journal of Field Robotics, EarlyView.
ABSTRACT The Abu Dhabi Autonomous Racing League (A2RL) x Drone Champions League (DCL) competition requires teams to perform high‐speed autonomous drone racing using only a single camera and a low‐quality inertial measurement unit—a minimal sensor set that mirrors expert human drone racing pilots.

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

Engineering ApoE‐Mimetic HDL‐Like Nanoparticles for Glioblastoma‐Targeted Theranostics

Small Methods, EarlyView.
An ApoE‐mimetic peptide enables the stable formation of sub‐30 nm HDL‐like nanoparticles (ApoEm‐PLP) that simultaneously engage multiple lipoprotein receptors. This multivalent receptor interaction facilitates the transport of ApoEm‐PLP into brain and enhances targeted delivery of ApoEm‐PLP to glioblastoma, resulting in uniform intratumoral porphyrin ...

Three‐dimensional meso‐scale finite element modeling of recycled aggregate concrete using cohesive zone method

Structural Concrete, EarlyView.
Abstract The presence of adhered mortar (AM) in recycled aggregates (RAs) significantly affects the mechanical performance of recycled aggregate concrete (RAC). Meso‐scale modeling provides valuable insights into complex phase interactions, enabling a better understanding of RAC behavior.
