Influence of Mechanical Yielding on Predictions of Saturation: The Saturation Line [PDF]

open access: yes, 2017
It is now well accepted that the mechanical and the water retention behaviour of a soil under unsaturated conditions are coupled and, that such coupling, should be incorporated into a constitutive model for a realistic representation of soil’s response ...

Global Saturation of Regularization Methods for Inverse Ill-Posed Problems

open access: yes, 2010
In this article the concept of saturation of an arbitrary regularization method is formalized based upon the original idea of saturation for spectral regularization methods introduced by A. Neubauer in 1994.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

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.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

open access: yesFEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

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.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Benchmarking of Sensor Configurations and Measurement Sites for Out-of-the-Lab Photoplethysmography

open access: yesSensors, 2023
Photoplethysmography (PPG) is used for heart-rate monitoring in a variety of contexts and applications due to its versatility and simplicity. These applications, namely studies involving PPG data acquisition during day-to-day activities, require reliable

Electrical resistivity at large temperatures: Saturation and lack thereof

open access: yes, 2002
Many transition metal compounds show saturation of the resistivity at high temperatures, T, while the alkali-doped fullerenes and the high-Tc cuprates are usually considered to show no saturation. We present a model of transition metal compounds, showing
