Ultra-Wideband Robust RCS Reduction with Triangle-type AMC Structure [PDF]

Radioengineering, 2018
A novel planar artificial magnetic conductor (AMC) structure is presented for ultra-wideband radar cross section reduction (RCSR). The structure consists of three different AMC tiles in a quadruple triangle-type chessboard configuration.

High-Gain Fabry-Perot Antennas With Wideband Low Monostatic RCS Using Phase Gradient Metasurface

IEEE Access, 2019
The design of two high-gain Fabry–Perot antennas with wideband low monostatic radar cross section (RCS) is presented in this paper. First, a phase gradient metasurface (PGM) without lossy layer is used to realize in-band RCS reduction and high ...

Inverse Vulcanized Sulfur Polymer Composites From Poultry‐Industry Products and Lignocellulosic Biomass Waste

Journal of Applied Polymer Science, EarlyView.
This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density

Clinical Anatomy, EarlyView.
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

A Novel Patient‐Specific Landmark‐Guided Approach for Intramuscular Botulinum Neurotoxin Injections Into the Rotator Cuff: A Cadaveric Study

Clinical Anatomy, EarlyView.
ABSTRACT Myofascial pain syndrome (MFPS) causes chronic shoulder pain. Supraspinatus and infraspinatus, rotator cuff muscles innervated by the suprascapular nerve, are commonly affected. Intramuscular botulinum neurotoxin (BoNT) injections near motor points (i.e., visible nerve branch entry sites used as a proxy for motor endplates) are an effective ...

Transforming Discourse, Transforming Practice: The Self‐Assessment Tool for Community Colleges

New Directions for Community Colleges, EarlyView.
ABSTRACT Community college faculty remain largely invisible in national data and in tools designed for four‐year institutions. This study uses critical discourse analysis (CDA) to examine how a faculty diversity self‐assessment tool, originally built on Griffin's Institutional Model for Increasing Faculty Diversity for four‐year universities, was ...

Aspire Regional Collaboratives: A Flexible Model for Cultivating a Diverse and Inclusive STEM Faculty at Community Colleges

New Directions for Community Colleges, EarlyView.
ABSTRACT The Aspire Regional Collaborative (RC) initiative fosters community college and university partnerships that strengthen pathways to STEM faculty positions in community colleges. In this study, we draw from the designing educational innovation for sustained adoption (DEISA) framework to document the progress of the RC initiative.

Centering Relationships, Active Teaching, and Career Development in One STEM Teaching Practicum

New Directions for Community Colleges, EarlyView.
ABSTRACT Broadening participation in STEM fields, particularly among underrepresented minority (URM) groups, has long been a national priority (AIR 2013; The Education Trust 2024). Community colleges—by virtue of their open access, diverse student populations, and teaching‐focused missions—are uniquely positioned to contribute to this effort.
