Summary: This study investigates the lateral bending of Ag nanowires under various bending angles and pushing velocities. It is found that fractures occur when the bending angle exceeds 80 degrees, and the mechanical performance is clarified based on high-resolution transmission electron microscope (HRTRM) detections. The presence of grain boundaries inside Ag nanowires is identified as a contributor to the generation of fractures and cracks during bending and nanoindentation.

Summary: Experimental results using balanced optical low-coherence interferometry to measure ultralow light power backreflected and/or back-scattered by optical interfaces demonstrate the method's ability to characterize critical noise sources in interferometric gravitational-wave detectors, while also quantifying the scattering properties of elementary optical components with high sensitivity.

Summary: This paper introduces a 3D-AFM-head with true 3D-probing capabilities for critical dimension measurements. The calibrated 3D-Nanoprobe shows a selectivity ratio of 50:1 on average for each of the spatial directions x, y, and z, with a quasi-isotropic ratio of stiffness. Testing on CD-line samples demonstrates promising results in terms of repeatability and accuracy.

Summary: By integrating a physically motivated model for the behavior of noise from scattered light into a standard Bayesian analysis pipeline, we can infer the free parameters and subtract them to obtain glitch-free data. Our study demonstrates that this inference method effectively discriminates the presence of glitch features, even when they are not visually discernible in standard data visualizations.

Summary: Ground-based gravitational wave detectors use laser interferometry to achieve precise displacement measurements and detect signals. To reduce noise caused by scattered light, researchers propose introducing high-speed noise modulations into the interferometer topology. Simulations show that tuning the coherence can significantly decrease the coupling of scattered light.

Summary: Evidence suggests that individuals with CRPS do not differ significantly from controls in MSA endpoint errors, and the arm used (Side of Body) does not have a significant impact on the results. In MSA tasks, pointing errors tend to be biased towards the hand being used.

Summary: In this paper, we propose a novel polarization-based approach that robustly estimates the background light to reduce the impact of noise in underwater image enhancement. The proposed method achieves better visual effect and robustness than the classic polarization-based and traditional underwater enhancement algorithms for different concentrations.

Summary: This article presents an unsupervised deep learning approach for attenuating coherent noise in land seismic data. The method utilizes a generator network to extract self-similar signal components and eliminate unwanted components. Experimental results demonstrate the significant advantages of this approach in reducing both random and coherent noise.

Summary: This study experimentally observed the optical back-action on the photothermal relaxation rate in an optical cavity strongly coupled to photothermal effects, successfully modifying the relaxation rate of the photothermal system. This approach provides a new way to accurately estimate the parameters of the cavity.

Summary: The prospect of massive parallelism of optics is attracting interest for novel photonic circuits, and 3D implementations have a high potential for scalability. However, as the technology for data input-output channels is 2D, there is a need to consider 2D-nD transformations. This review focuses on iterative techniques and neural networks in tackling 3D-2D transformations across different fields, providing a useful perspective for 3D optical design.

Summary: This study presents a portable and handheld 2-channel polarization-sensitive imaging instrument that can directly resolve terahertz (THz) speckle fields. It measures the polarization state of THz light and presents it in the form of the Stokes vectors of the THz beam upon interaction with the sample. The technique has been validated in surface scattering experiments and shows a strong dependence of the polarization state on surface roughness and THz frequency. It provides a fast method for broadband THz polarimetric measurement in various applications.

Summary: Atomic force microscopy (AFM) is a powerful technique for high-resolution imaging of molecules, macromolecular complexes, and nanoparticles. However, the shape of the AFM tip can distort the images. In this study, we use a 3D DNA origami structure as a fiducial for tip reconstruction and image correction. The fiducial has sharp steps at different heights, allowing reliable tip reconstruction with as few as ten fiducials. This fiducial enables accurate and precise AFM imaging for a wide range of applications.

Summary: Protein-lipid interfaces are fundamental in biology, but studying the biophysical attributes of these systems using conventional techniques is challenging. This review discusses the experimental and theoretical progress in addressing the kinetic pathway and energy landscape experienced by a polypeptide chain near a fluid lipid bilayer from a single molecule perspective, and highlights some remaining impediments.
