Analysis of mechanical action between cone end of borehole packer and coal dregs in borehole and its application

open access: yesMeikuang Anquan
Analysis of mechanical action between cone end of borehole packer and coal residue in borehole is helpful to improve speed and depth of borehole packer movement by drag reduction effect of cone end. Firstly, on the basis of force analysis about cone end,

Structural but Not Functional Alterations in Cones in the Absence of the Retinal Disease Protein Retinitis Pigmentosa 2 (RP2) in a Cone-Only Retina

open access: yesFrontiers in Genetics, 2019
X-linked retinitis pigmentosa 2 (XLRP2) patients and Rp2null mice exhibit severe cone photoreceptor degeneration. However, due to the paucity of cones in mammalian model systems, it is not clear how cones respond to the loss of RP2. Here we have used the

Self‐Feeding of Engineered Tissues via Controlled Glucose Release Facilitates Survival and Vascularization of Living Implants

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Engineering living matter has great clinical potential to deliver functional replacement organs. However, clinical translation remains hampered by the current inability to maintain viability of clinically relevant‐sized constructs. During the pre‐vascular phase, implants rely on nutrient diffusion for survival, which is insufficient at ...

Reconstruction of an AdS Radiation/Boson Star Bulk Geometry Using Light-cone Cuts

open access: yes, 2017
Light-cone cuts have recently been proposed as a method to reconstruct the conformal metric of a holographic spacetime. We explore how additional information about the bulk geometry gets encoded in the structure of these light-cone cuts.

Novel Functional Materials via 3D Printing by Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Analysis on Locking Mechanism Performance of SCM Running Tool for Subsea Horizontal X-tree

open access: yesShiyou jixie, 2016
The locking element is the most significant part of the whole SCMRT.In the theoretical analysis,locking angle,unlocking angle and cone angle are mainly considered for the lock block.Self-locking would not occur when the lock angle α is larger than 8.5 ...

Crescent Singularities in Crumpled Sheets

open access: yes, 2004
We examine the crescent singularity of a developable cone in a setting similar to that studied by Cerda et al [Nature 401, 46 (1999)]. Stretching is localized in a core region near the pushing tip and bending dominates the outer region.

Using Long‐Chain Polymechanophores to Explore the Differences in Mechanoactivation During Nozzle Flow and Ultrasonication

open access: yesAdvanced Functional Materials, EarlyView.
Flow through a nozzle is a common component of most fluid‐based polymer processing techniques such as spray drying, inkjet printing, extrusion. An ultrahigh molecular weight multi‐mechanophore system is used to probe the differences in the distribution of mechanical activation observed between nozzle flow and ultrasonication; the gold standard ...

Cavity expansion theory with state-dependent mohr-coulomb model and its application to cone penetration tests.

open access: yesPLoS ONE
The cone penetration test (CPT) is a fast and efficient in-situ testing technique that provides reliable and continuous measurements of soil properties. The CPT calibration chamber test is widely used to investigate soil-pile interactions. To address the

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...
