The chloroplast genome evolution of Venus slipper (Paphiopedilum): IR expansion, SSC contraction, and highly rearranged SSC regions

open access: yesBMC Plant Biology, 2021
Paphiopedilum is the largest genus of slipper orchids. Previous studies showed that the phylogenetic relationships of this genus are not well resolved, and sparse taxon sampling documented inverted repeat (IR) expansion and small single copy (SSC ...

A Mixed Lubrication Model for Predicting the Lubrication Performance Degradation Behavior of Slipper Pair in Early Wear Failure

open access: yesIEEE Access, 2023
To reveal the lubrication performance degradation mechanism of the slipper pair in the high-pressure piston pump during early wear failure. The three-dimensional fractal function has been used to construct the surface morphology of the slipper, and ...

Analysis of Slipper Overturning and Collision Behavior of the Axial Piston Pump Based on Rigid-Flexible Coupling

open access: yesIEEE Access, 2023
In the working process of the axial piston pump, the composite multi-degree motion of the slipper and its coupling, as well as the complex working conditions, cause the slipper to overturn and collide irregularly with its coupling. The overturning of the

Study on the Lubricating Characteristics of the Oil Film of the Slipper Pair in a Large Displacement Piston Pump

open access: yesLubricants, 2023
Due to the large size of the bottom surface, the slipper pair of the large displacement piston pump (LDPP) will form a larger linear speed difference in the inner and outer positions of the slipper relative to the center of the swash plate during high ...

Numerical-experimental observation of shape bistability of red blood cells flowing in a microchannel [PDF]

open access: yes, 2017
Red blood cells flowing through capillaries assume a wide variety of different shapes owing to their high deformability. Predicting the realized shapes is a complex field as they are determined by the intricate interplay between the flow conditions and ...

Squeeze Film Effect and Its Influence on the Lubrication Characteristics of Slipper Oil Film under Pressure Pulse

open access: yesShock and Vibration, 2023
This study aims at the lubricant film between the slipper and swashplate of an axial piston pump. Based on a single piston/slipper assembly model, a mathematical model for the squeeze film effect is developed according to the pressure-flow transfer ...

Exosome, the glass slipper for Cinderella of cancer—bladder cancer?

open access: yesJournal of Nanobiotechnology, 2023
Exosomes are lipid bilayer vesicles with a diameter of 40–100 nm secreted by almost all cells. They have been found play crucial regulatory roles in various diseases.

The evolution of a key character, or how to evolve a slipper lobster [PDF]

open access: yes, 2016
International audienceA new fossil lobster from the Cretaceous of Lebanon, Charbelicaris maronites gen. et sp. nov., is presented here, while the former species ‘Cancrinos’ libanensis is re-described as Paracancrinos libanensis comb. nov. P.
