Channel Characterization of Magnetic Human Body Communication.

IEEE Trans Biomed Eng 2021 Aug 4;PP. Epub 2021 Aug 4.

Objective: The objective of this paper is to model and experimentally validate the path loss benefits of magnetic human body communication (mHBC) using small form-factor-accurate coils operating under realistic conditions.

Methods: A radiating near-field coupling model and numerical simulations are presented to show that the magnetic-dominant near-field coupling between resonant coils offers low path loss across the body and exhibits extra robustness to antenna misalignment compared to far-field RF schemes. To overcome the pitfalls in conventional vector-network-analyzer-based measurement configurations, we propose a standardized setup applied to broadband channel loss measurement with portable instruments.

Conceptual Ex-Ante Simulation for Green Stormwater Infrastructure Adoption on Private Property Using Agent-Based Modeling.

Water Environ Res 2021 Aug 3. Epub 2021 Aug 3.

Water Environment Federation, Alexandria, Virginia, USA.

This paper presents the Green Stormwater Infrastructure Social Spatial Adoption (G-SSA) model, a cellular automata agent-based model that simulates the behavior of private property owners responding to incentives to adopt on-site green stormwater infrastructure (GSI). Concepts such as small-world social networks, opinion dissemination and diffusion of innovation are used to capture dynamic social, spatial and temporal aspects of green stormwater infrastructure adoption. Demographic information, site constraints, GSI practice type and costs, and financial incentive information are integrated into modeling rules that influence adoption dynamics. Read More

Combined atomic and molecular (CAM) ionization with the liquid sampling-atmospheric pressure glow discharge microplasma.

Mass Spectrom Rev 2021 Aug 4. Epub 2021 Aug 4.

Environmental Molecular Sciences Laboratory, Pacific Northwest National Laboratory, Richland, Washington, USA.

In a world where information-rich methods of analysis are often sought over those with superior figures of merit, there is a constant search for ionization methods which can be applied across diverse analytical systems. The liquid sampling-atmospheric pressure glow discharge (LS-APGD) is a microplasma device which has the inherent capabilities to operate as a combined atomic and molecular (CAM) ionization source. The plasma is sustained by placement of a high voltage (~500 V, dc) onto an electrolytic solution through which the analyte is generally delivered to the discharge. Read More

Comparison of the basic morphology and function of 3D lung epithelial cultures derived from several donors.

Curr Res Toxicol 2020 Jun 4;1:56-69. Epub 2020 Sep 4.

PMI R&D, Philip Morris Products S.A., Quai Jeanrenaud 5, 2000 Neuchâtel, Switzerland.

In vitro models of the human lung play an essential role in evaluating the toxicity of inhaled compounds and understanding the development of respiratory diseases. Three-dimensional (3D) organotypic models derived from lung basal epithelial cells and grown at the air-liquid interface resemble human airway epithelium in multiple aspects, including morphology, cell composition, transcriptional profile, and xenobiotic metabolism. Whether the different characteristics of basal cell donors have an impact on model characteristics and responses remains unknown. Read More

Can Vet J 2021 Aug;62(8):857-860

Department of Veterinary Biosciences and Diagnostic Imaging (Gendron, Perlini), Department of Pathology (Howerth), Department of Small Animal Medicine and Surgery (Nagata, Northrup), College of Veterinary Medicine, University of Georgia, Athens, Georgia 30602, USA.

Two adult neutered male dogs were presented for evaluation of firm, painless masses arising within muscle: an 8-year-old German wirehaired pointer dog with an accessory tricipital growth, and a 3-year-old German shepherd dog with a gracilis muscle growth. Magnetic resonance imaging (MRI) characteristics suggested malignant behavior, with a central fluid-like portion with a hyperenhancing lining, a nidus of disorganized tissue, and an extensive reactive zone, whereas histopathology was consistent with low-grade fibrosarcoma. This report describes histologically low-grade, yet biologically high-grade intramuscular fibrosarcoma, in which MRI provided detailed information on tumor behavior and assisted with biopsy and surgical planning.

Phase shift approach for engineering desired radiation force: Acoustic pulling force example.

J Acoust Soc Am 2021 Jul;150(1):102

National Center for Physical Acoustics and Department of Physics and Astronomy, University of Mississippi, Oxford, Mississippi 38677, USA.

Phase shifts from scattering are used to analyze and engineer acoustic radiation forces. With the aid of phase shifts, analytical results for acoustic radiation forces can be simplified into compact and physically meaningful expressions, which can be used to develop a simplified procedure for the engineering of the radiation force. The desired radiation force can be fulfilled by a specific set of phase shifts up to a certain order, and then the required phase shifts can be fulfilled by engineering object and beam parameters.
