Entropy Driven Phase Transition in Polymer Gels: Mean Field Theory

open access: yesEntropy, 2018
We present a mean field model of a gel consisting of P polymers, each of length L and Nz polyfunctional monomers. Each polyfunctional monomer forms z covalent bonds with the 2P bifunctional monomers at the ends of the linear polymers.

Analyzing the Saturation of Growing Stem Volume Based on ZY-3 Stereo and Multispectral Images in Planted Coniferous Forest

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Recently, remote sensing (RS) technology are becoming an increasingly important technology in estimating forest growing stem volume (GSV), and the saturation issue of spectral variables from various optical sensors severely hinders the improvement of ...

Transferrin Saturation and Mortality [PDF]

open access: yesClinical Chemistry, 2011
To the Editor: Ellervik and colleagues (1) recently reported a positive association between transferrin saturation (TS) and mortality. Several questions arise from this observation: Is the association due to all causes of iron overload or to hereditary hemochromatosis only? Does the study underestimate the true association?

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Chronological Incongruences between Mitochondrial and Nuclear Phylogenies of Aedes Mosquitoes

open access: yesLife, 2021
One-third of all mosquitoes belong to the Aedini, a tribe comprising common vectors of viral zoonoses such as Aedes aegypti and Aedes albopictus.

Influence of Magnetic Saturation of Iron-Core on Performance of Thyristor Phase Control Circuit

open access: yes, 1982
The influence of magnetic saturation of iron-core on the performance of thyristor phase control circuit with series RLC elements is described. The circuit is analyzed by applying an approximate model of three straight lines to the flux Φ vs.

Dietary N-3 polyunsaturated fatty acids decrease biliary cholesterol saturation in gallstone disease [PDF]

open access: yes, 1992
Because fatty acid composition of biliary phospholipids influences cholesterol secretion into bile, we investigated whether replacement of n-1 monounsaturated or n-6 polyunsaturated fatty acids with n-3 polyunsaturated fatty acids in biliary ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

The Influencing Factors and Calculation Methods of Rock Electrical Parameters of Carbonate Reservoirs

open access: yesCejing jishu
The pore structure of carbonate reservoir is much more complex than that of clastic reservoir, and its rock electrical parameters m and n vary widely, which is difficult to obtain accurately, and the fixed rock electrical parameters are used to calculate

Effect of apparent gas velocity on performance of oleophobic coalescence filter cartridge and its structure improvement

open access: yesYou-qi chuyun, 2022
The frequent fluctuation of gas flow during the storage and transportation can easily lead to the failure of filter cartridge and the shortening of its service life.
