Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Rate-Dependent Response of Dense Sand in Cyclic Triaxial Tests

Soils and Foundations, 2008
A number of cyclic triaxial tests were performed on Monterey No. 0/30 and Sacramento River Sand to investigate the effect that loading frequency has on the response of sands. The tests were performed on dense, air pluviated sand with loading frequencies of 0.1 and 1.5 Hz at varying confining pressures, cyclic shear stresses, and peak shear stresses ...

EndoTac: An Endoscopic Camera‐Based Tactile Sensor with High Sensitivity for Minimally Invasive Surgery

Advanced Science, EarlyView.
EndoTac presents a trocar‐compatible endoscopic vision‐based tactile sensor that uses a convex mirror to enlarge side‐facing tactile coverage during minimally invasive vessel palpation. Distorted tactile images are unwarped and processed by a learning model to estimate vascular deformation, enabling sensitive, spatially distributed tactile perception ...

Evolution of the Damping Ratio Considering Cyclic Confining Pressure Under Intermittent Cyclic Loading

Buildings
The damping ratio is essential to conducting dynamic analysis for underground engineering under traffic loading. Variations in the damping ratio are usually studied using cyclic triaxial tests with continuous cyclic loading; however, intermittent loading

Some contributions to mechanical behaviors of lacustrine deposit in Bogotá, Colombia

Journal of Rock Mechanics and Geotechnical Engineering, 2019
This paper presents the mechanical behaviors of the lacustrine deposit, a representative soil in Bogotá, Colombia. Initially, the physical characterization of the deposit is performed via laboratory tests (grain size distribution, scanning electron ...

The specific deviatoric energy to liquefaction in saturated cyclic triaxial tests

Proc. of the 7th International Conference on Earthquake Geotechnical Engineering, 2019
Within the European project LIQUEFACT, cyclic triaxial tests were carried out on an Italian sand, Pieve di Cento sand, taken from a field trial located in Emilia Romagna (Ita-ly), which was affected by liquefaction during the 2012 earthquake. The cyclic resistance curve of that sand was obtained in laboratory on reconstituted specimens with a low ...

Research on micro-influence mechanism of fine particles on dynamic characteristics of graded macadam materials in heavy-haul railway subgrade beds

Case Studies in Construction Materials, 2023
Fine particle content is an important physical state parameter of graded macadam materials used in heavy-haul railway subgrade beds. Understanding the micro-influence mechanism of the fine particle content on the filler’s dynamical characteristics is of ...
