Structural Polymorphism of polyG Inclusions Revealed by In Situ Cryo‐Electron Tomography

open access: yesAdvanced Science, EarlyView.
Correlative cryo‐electron tomography in primary cortical neurons and NIID mouse brain tissue reveals that polyG inclusions are interconnected ribbon‐like assemblies rather than canonical amyloid fibrils. Multiple compartment‐specific ribbon states show distinct 26S proteasome accessibility, while cytoplasmic ribbons contact and deform ER‐like ...

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

open access: yesAdvanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

Preliminary study on intelligent control of natural gas pipeline networks

open access: yesYou-qi chuyun, 2021
As the "decision-making brain" of a pipeline network system, the control centre is a comprehensive decision-making control centre that integrates large amounts of data, rules and expert experience. It is very similar to the development idea and evolution direction of a new generation of artificial intelligence characterized by data driving. Herein, the

GPU-accelerated hydraulic simulations of large-scale natural gas pipeline networks based on a two-level parallel process

open access: yes, 2020
The numerical simulation efficiency of large-scale natural gas pipeline network is usually unsatisfactory. In this paper, Graphics Processing Unit (GPU)-accelerated hydraulic simulations for large-scale natural gas pipeline networks are presented. First,

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

open access: yesAdvanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Effect of Cr content on softening mechanism of the heat-affected zone of X80 GMAW automatic girth weld

open access: yesJournal of Pipeline Science and Engineering
Softening of the heat-affected zone (HAZ) could lead to strain concentration in the girth weld joint, which endangers the service safety of high strength pipelines, while the chemical composition and original microstructure of pipeline steel play a ...
