Luminescent Donor-Acceptor Radical With Propeller Chirality: Bright and Photostable Red Circularly Polarized Luminescence and Whispering Gallery Mode Resonance. [PDF]

open access: yesAngew Chem Int Ed Engl
A 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]

open access: yesThorac 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 ...

Fluorescence-line-selective soft X-ray absorption spectroscopy: a novel approach to element-specific electronic structure analysis. [PDF]

open access: yesJ Synchrotron Radiat
Fluorescence‐line‐selective soft X‐ray spectroscopy using a superconducting tunnel junction (STJ) detector was applied to probe the electronic states of strontium titanate, demonstrating the capability of the STJ detector for high‐energy‐resolution soft X‐ray absorption spectroscopy.A novel approach to soft X‐ray fluorescence‐yield absorption ...

Mechanical Deformation Analysis of a Flexible Finger in Terms of an Improved ANCF Plate Element

open access: yesMachines, 2022
In recent years, flexible continuum robots have been substantially developed. Absolute nodal coordinates formulation (ANCF) gives a feasible path for simulating the behavior of flexible robots. However, the model of finger-shaped robots is often regarded

A Variable-Length Rational Finite Element Based on the Absolute Nodal Coordinate Formulation

open access: yesMachines, 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

Reduction of degrees of Freedom in three-dimensional ANCF beam of 24-DOF beam element by component mode synthesis

open access: yesNihon Kikai Gakkai ronbunshu, 2014
This paper describes how to reduce degrees of freedom for the absolute nodal coordinate formulation (ANCF) of three-dimensional beam made up of 24 degrees of freedom beam elements by applying the component mode synthesis. The stiffness matrix of the ANCF

Reversible Transition between Discrete and 1D Infinite Architectures: A Temperature‐Responsive Cu(I) Complex with a Flexible Disilane‐Bridged Bis(pyridine) Ligand

open access: yesChemistry – A European Journal, Volume 29, Issue 38, July 6, 2023., 2023
Thermoresponsive molecular structure based on a disilane‐bridged bis(pyridyl) ligand and CuI is reported. Single‐crystal X‐ray analysis revealed that there were two polymorphs in the Cu(I) complex: octanuclear copper(I) complex at 20 °C and 1D staircase copper(I) polymer complex at −173 °C. The formation of these polymorphs is due to the flexibility of
