Modeling transport of soft particles in porous media.

Phys Rev E 2021 Aug;104(2-2):025112

Department of Mechanical Engineering, The City College of New York, New York, New York 10031, USA.

Flow-driven transport of soft particles in porous media is ubiquitous in many natural and engineering processes, such as the gel treatment for enhanced oil recovery. In many of these processes, injected deformable particles block the pores and thus increase the overall pressure drop and reduce the permeability of the particle-resided region. The change of macroscopic properties (e. Read More

Nondestructive Microanalysis of Thin-Film Coatings on Historic Metal Threads.

Anal Chem 2021 Sep 15. Epub 2021 Sep 15.

Museum Conservation Institute, Smithsonian Institution, 4210 Silver Hill Road, Suitland, Maryland 20746, United States.

A new standards-based scanning electron microscopy with the energy-dispersive X-ray spectrometry (SEM-EDS) quantification method was used to analyze the thin-film coating of an 18th century French textile decorated with metal threads in variable pressure conditions. This analytical technique can allow for nondestructive quantitative characterization of the near surface of cultural heritage objects small enough to be placed in an SEM chamber that may contain corrosion products, without applying a conductive coating. A multivoltage analysis consisting of measurements taken at a series of electron beam energies was obtained and input into a film thickness and composition (FTC) computational model to characterize a layered Au on Ag reference material, in addition to a historic metal thread.

J Med Virol 2021 Sep 15. Epub 2021 Sep 15.

Department of Clinical Laboratory, Saitama Medical University Hospital, Saitama, Japan.

Fully automated immunoassays for detecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies that are strongly correlated with neutralization antibodies (nAbs) are clinically important because they enable assessment of humoral immunity after infection and vaccination. Access SARS-CoV-2 IgM and IgG II antibody tests are semi-quantitative, fully automated immunoassays that detect anti-receptor-binding domain (RBD) antibodies and might reflect nAb levels in coronavirus disease 2019 (COVID-19). However, no studies have investigated the clinical utility of these tests in association with nAbs to date. Read More

JMIR Mhealth Uhealth 2021 Sep 15;9(9):e31637. Epub 2021 Sep 15.

Graduate School of Technology Management, Ritsumeikan University, Ibaraki, Japan.

Background: A construction method has emerged in which a camera is installed around a construction machine, and the operator remotely controls the machine while synchronizing the vibration of the machine with the images seen from the operator's seat using virtual reality (VR) technology. Indices related to changes in heart rate (HR) and physical vibration, such as heart rate variability (HRV) and multiscale entropy (MSE), can then be measured among the operators. As these indices are quantitative measures of autonomic regulation in the cardiovascular system, they can provide a useful means of assessing operational stress. Read More

Conductive hearing loss in the Hyp mouse model of X-linked hypophosphatemia is accompanied by hypomineralization of the auditory ossicles.

J Bone Miner Res 2021 Sep 15. Epub 2021 Sep 15.

Department of Trauma and Orthopaedic Surgery, Division of Orthopaedics, University Medical Center Hamburg-Eppendorf; Hamburg, Germany.

X-linked hypophosphatemia (XLH) is a hereditary musculoskeletal disorder caused by loss-of-function mutations in the PHEX gene. In XLH, increased circulating fibroblast growth factor 23 (FGF23) levels cause renal phosphate wasting and low concentrations of 1,25-dihydroxyvitamin D, leading to an early clinical manifestation of rickets. Importantly, hearing loss is commonly observed in XLH patients. Read More

All-optical dynamic analysis of the photothermal and photoacoustic response of a microcantilever by laser Doppler vibrometry.

Photoacoustics 2021 Dec 31;24:100299. Epub 2021 Aug 31.

Laboratory for Soft Matter and Biophysics, Department of Physics and Astronomy, KU Leuven, Leuven, B-3001, Belgium.

Light absorption induced thermoelastic and photoacoustic excitation, combined with laser Doppler vibrometry, was utilized to analyze the dynamic mechanical behavior of a microcantilever. The measured frequency response, modal shapes, and acoustic coupling effects were interpreted in the framework of a simple Bernouilli-Euler model and quantitative 3D finite element method (FEM) analysis. Three opto-mechanical generation mechanisms, each initiated by modulated optical absorption and heating, were identified both by an analytical and finite element model. Read More
