Simplified fatigue life analysis for traction drive contacts [PDF]

open access: yes
A simplified fatigue life analysis for traction drive contacts of arbitrary geometry is presented. The analysis is based on the Lundberg-Palmgren theory used for rolling-element bearings. The effects of torque, element size, speed, contact ellipse ratio,

Traction force microscopy with optimized regularization and automated Bayesian parameter selection for comparing cells

open access: yes, 2018
Adherent cells exert traction forces on to their environment, which allows them to migrate, to maintain tissue integrity, and to form complex multicellular structures.

Inference of internal stress in a cell monolayer [PDF]

open access: yes, 2016
We combine traction force data with Bayesian inversion to obtain an absolute estimate of the internal stress field of a cell monolayer. The method, Bayesian inversion stress microscopy (BISM), is validated using numerical simulations performed in a wide ...

Precise Control of Drug Release in Machine Learning‐Designed Antibody‐Eluting Implants for Postoperative Scarring Inhibition in Glaucoma

open access: yesAdvanced Healthcare Materials, EarlyView.
We developed a micro‐sized, biocompatible implant for postoperative sustained delivery of anti‐fibrotic antibodies in glaucoma surgery. Machine learning‐guided optimization of polymer composition, implant geometry, and porosity enabled precise control of drug release.

A mobile planetary lander utilizing elastic loop suspension [PDF]

open access: yes, 1976
Efforts to increase the cost effectiveness of future lunar and planetary rover missions have led to the mobile lander concept, which replaces the landing legs of a soft-lander craft with a compact mobility system of sufficient strength to withstand the ...

A 3D Bioprinted Spheroid‐Laden dECM‐Enriched Osteosarcoma Model for Enhanced Drug Testing and Therapeutic Discovery

open access: yesAdvanced Healthcare Materials, EarlyView.
A 3D biomimetic OS model was developed by bioprinting an OS‐cell‐derived dECM‐enriched bioink with OS spheroids incorporated. The model showed upregulation of known OS prognostic markers and increased resistance to doxorubicin, compared to 2D cultures and scaffold‐free spheroids, making this a more clinically relevant platform for drug discovery ...

Bilateral Tripping and Self-healing Scheme for Urban Rail Transit DC Traction Power Supply System Based on GOOSE Communication

open access: yesChengshi guidao jiaotong yanjiu
Objective The structure of DC (direct current) traction power supply system for urban rail transit is complex and without any backup power supply. Once a malfunction occurs, it may directly lead to a train-stopping accident.

Spatial Patterning of Modular Gelatin‐Peroxide Microspheres in Melt‐Electrowritten Scaffolds Provides Controlled Oxygen Generation and Mitigates Hypoxia and Cytotoxicity

open access: yesAdvanced Healthcare Materials, EarlyView.
A bioassembly approach is described using photo‐crosslinked gelatin‐based microgels containing calcium peroxide (CaO2) to generate oxygen (O2) and enhance cell survival in hypoxic conditions (1% O2). Bioassembly enables spatial patterning of individual CaO2‐laden and mesenchymal stem cell (MSC)‐laden microgels and allows for decoupling and mitigating ...
