Experimental Study on Flexible Fiber Assisted Shear Thickening Polishing for Cutting Edge Preparation of Core Drill

Lubricants, 2023
To improve the cutting performance of the core drill, the flexible fiber assisted shear-thickening polishing (FF-STP) for cutting edge preparation was proposed to eliminate the microscopic defect and obtain proper radius of the cutting edge of the core ...

Where is the Inner Edge of an Accretion Disk Around a Black Hole? [PDF]

, 2002
What is meant by the "inner edge" of an accretion disk around a black hole depends on the property that defines the edge. We discuss four such definitions using data from recent high-resolution numerical simulations.

Optimal Tooth Flank Modifications for Compound Planetary Robot Reducer Considering Edge Contact

IEEE Access
The aim of this study was to optimize gear tooth flank modification in a compound planetary reducer with a reduction ratio of 100:1 to achieve uniform load distribution and minimize the face load factor ( $K_{H\beta }$ ).

Field Theoretical Description of Quantum Hall Edge Reconstruction

, 2003
We propose a generalization of the chiral Luttinger liquid theory to allow for a unified description of quantum Hall edges with or without edge reconstruction.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Topological Entanglement Entropy from the Holographic Partition Function

, 2006
We study the entropy of chiral 2+1-dimensional topological phases, where there are both gapped bulk excitations and gapless edge modes. We show how the entanglement entropy of both types of excitations can be encoded in a single partition function.

Characterisation of contact pressure distribution in bolted joints [PDF]

, 2006
The quantification of contact area and pressure distribution in a bolted joint is essential information, as it determines the integrity of the coupling. Current bolted joint design standards are based on analytical solutions of the pressure distribution,

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Tip-rem modification for full tooth surface pattern and require no edge contact of high loaded capacity cycloidal hypoid gears

Xibei Gongye Daxue Xuebao
The full tooth surface pattern and require no edge contact design of cycloid bevel gears based on Tip-rem is a novel gear optimization design method, which aimed at optimizing contact performance of gears and preventing edge contact, thus improving the ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
