Consistency of nonlinear regression quantiles under Type I censoring weak dependence and general covariate design [PDF]

For both deterministic or stochastic regressors, as well as parametric nonlinear or linear regression functions, we prove the weak consistency of the coefficient estimators for the Type I censored quantile regression model under different censoring ...

UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

Advanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.

Asymptotic Theory for Local Time Density Estimation and Nonparametric Cointegrating Regression [PDF]

We provide a new asymptotic theory for local time density estimation for a general class of functionals of integrated time series. This result provides a convenient basis for developing an asymptotic theory for nonparametric cointegrating regression and ...

Grip and Grasp: Lizard Claw Inspired Robotic Manipulators

Advanced Robotics Research, EarlyView.
Our study identifies the most effective lizard claw shape for use as an end effector in a bioinspired robotic manipulator. By examining key geometric features and combining them into comparative indices, the Crotaphytus collaris claw is found to be the best fit.

A generalized van Genuchten model for unsaturated soil hydraulic conductivity

Vadose Zone Journal
The hydrodynamics of variably saturated soils or porous media in general are described via nonlinear functions of water retention and hydraulic conductivity, which facilitate the simulation of various mass and energy transport processes (e.g., water ...

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

Advanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Cellular Snowballing: Cell Adhesion and Migration Drive the Self‐Assembly of Cell‐Microgel Biohybrid Spheroids

Advanced Science, EarlyView.
A new class of biohybrid spheroids is engineered through the self‐assembly of adherent cells and extracellular matrix‐mimetic hydrogel microparticles (microgels). By mimicking a snowballing effect, this approach enables scalable formation of porous, millimeter‐scale spheroids with enhanced cell viability and molecular diffusion.

Enhancing Generalization Capability of Tool Wear Prediction in Drilling Process Using Nonlinear Regression

International Journal of Automation Technology
The rapidly increasing demand for automation and efficiency in human resources within flexible manufacturing systems has made automated and systematic tool condition monitoring (TCM) and high-precision real-time anomaly detection essential for the cutting process. Drilling is crucial among cutting operations because inaccuracies can result in errors in

Discovery of SKP2‐Recruiting PROTACs for Target Protein Degradation

Advanced Science, EarlyView.
Based on the SKP2‐targeting ligand SL1, we designed non‐covalent PROTACs by linking it with the BRD4 inhibitor JQ1 and the AR antagonist AL through a linker. These PROTACs successfully induced the ubiquitination of BRD4 and AR, followed by proteasome‐mediated degradation.
