Luminescent Donor-Acceptor Radical With Propeller Chirality: Bright and Photostable Red Circularly Polarized Luminescence and Whispering Gallery Mode Resonance. [PDF]
Angew Chem Int Ed EnglA series of donor‐attached brominated chiral luminescent radicals (CzTTBrM, 2CzTTBrM, and 3CzTTBrM) was synthesized, showing red to near‐infrared (NIR) circularly polarized luminescence (CPL) with exceptionally high PLQY of up to 76% and markedly enhanced CPL brightness (BCPL). Doping into polystyrene microspheres further yields whispering gallery mode

Correlations between pathogenic variants in DNA repair genes and anticancer treatment efficacy in stage IV non-small cell lung cancer: A large real-world cohort and review of the literature. [PDF]
Thorac Cancer, 2023 Our retrospective data suggest that in patients with stage 4 NSCLC, pathogenic variants in DDR pathway genes may be associated with higher efficacy of radiotherapy and immune checkpoint inhibitors. This should be further explored prospectively. Abstract Background Mutations in genes involved in DNA damage repair (DDR), a hallmark of cancer, are ...

Stable Inversion for Flexible Multibody Systems Using the ANCF [PDF]
PAMM, 2021 AbstractFlexible robots are often non‐minimum phase systems. Thus, their inverse model must be computed by stable inversion. Here, a simplification to the stable inversion process is proposed, which enables its application to complex underactuated multibody systems.

Application of Stable Inversion to Flexible Manipulators Modeled by the ANCF
CoRR, 2022 Compared to conventional robots, flexible manipulators offer many advantages, such as faster end-effector velocities and less energy consumption. However, their flexible structure can lead to undesired oscillations. Therefore, the applied control strategy should account for these elasticities.

A Variable-Length Rational Finite Element Based on the Absolute Nodal Coordinate Formulation
Machines, 2022 The variable-length arbitrary Lagrange–Euler absolute nodal coordinate formulation (ALE-ANCF) finite element, which employs nonrational interpolating polynomials, cannot exactly describe rational cubic Bezier curves such as conic and circular curves. The
