High-Frequency Dielectrophoresis Reveals That Distinct Bio-Electric Signatures of Colorectal Cancer Cells Depend on Ploidy and Nuclear Volume
(MDPI, 2023-09-01)Aneuploidy, or an incorrect chromosome number, is ubiquitous among cancers. Whole-genome duplication, resulting in tetraploidy, often occurs during the evolution of aneuploid tumors. Cancers that evolve through a tetraploid ... -
Examining the Setting of Significant Learning Events during the Engineering School-to-Work Transition
(MDPI, 2023-08-26)The school-to-work transition is a critical time for engineers that involves rapid learning across multiple fronts, but relatively little is known about the setting (i.e., how, where, and with whom) of significant learning ... -
Unsupervised Multitaper Spectral Method for Identifying REM Sleep in Intracranial EEG Recordings Lacking EOG/EMG Data
(MDPI, 2023-08-25)A large number of human intracranial EEG (iEEG) recordings have been collected for clinical purposes, in institutions all over the world, but the vast majority of these are unaccompanied by EOG and EMG recordings which are ... -
Design of a Sensor-Technology-Augmented Gait and Balance Monitoring System for Community-Dwelling Older Adults in Hong Kong: A Pilot Feasibility Study
(MDPI, 2023-09-21)Routine assessments of gait and balance have been recognized as an effective approach for preventing falls by issuing early warnings and implementing appropriate interventions. However, current limited public healthcare ... -
Exploratory Development of Algorithms for Determining Driver Attention Status
(SAGE, 2023-09)Objective: Varying driver distraction algorithms were developed using vehicle kinematics and driver gaze data obtained from a camera-based driver monitoring system (DMS). Background: Distracted driving characteristics ... -
Pericyte Progenitor Coupling to the Emerging Endothelium during Vasculogenesis via Connexin43
(Lippincott Williams & Wilkins, 2022-04-01)Background: Vascular pericytes stabilize blood vessels and contribute to their maturation, while playing other key roles in microvascular function. Nevertheless, relatively little is known about involvement of their ... -
Scale modeling of thermo-structural fire tests
(Wiley, 2023-03)Standard methods for fire resistance testing require large-scale assemblies and are typically conducted on specialized furnaces at considerable cost. This research focused on developing a scaling methodology for a reduced-scale ... -
Norepinephrine links astrocytic activity to regulation of cortical state
(Nature Portfolio, 2023-04)Cortical state, defined by population-level neuronal activity patterns, determines sensory perception. While arousal-associated neuromodulators-including norepinephrine (NE)-reduce cortical synchrony, how the cortex ... -
Power device breakdown mechanism and characterization: review and perspective
(IOP Publishing, 2023-04)Breakdown voltage (BV) is arguably one of the most critical parameters for power devices. While avalanche breakdown is prevailing in silicon and silicon carbide devices, it is lacking in many wide bandgap (WBG) and ultra-wide ... -
Mining Tenure and Job Duties Differ Among Contemporary and Historic Underground Coal Miners With Progressive Massive Fibrosis
(Lippincott Williams & Wilkins, 2023-04)Objective: To characterize differences in mining jobs and tenure between contemporary (born 1930+, working primarily with modern mining technologies) and historic coal miners with progressive massive fibrosis (PMF). Methods: ... -
Global Variations in the Time Delays Between Polar Ionospheric Heating and the Neutral Density Response
(American Geophysical Union, 2023-04)We present results from a study of the time lags between changes in the energy flow into the polar regions and the response of the thermosphere to the heating. Measurements of the neutral density from the Challenging ... -
Sizing optimization and experimental characterization of a variable stiffness shape memory polymer filled honeycomb composite
(IOP Publishing, 2023-04)Variable stiffness structures and materials have been considered for many applications, including active vibration control and shape morphing. With regards to shape morphing, variable stiffness materials and composites ... -
Reducing the Ionospheric Contamination Effects on the Column O/N-2 Ratio and Its Application to the Identification of Non-Migrating Tides
(American Geophysical Union, 2023-04)Prior investigations have attempted to characterize the longitudinal variability of the column number density ratio of atomic oxygen to molecular nitrogen (SO/N-2) in the context of non-migrating tides. The retrieval of ... -
In-Flight Performance of the ICON EUV Spectrograph
(Springer, 2023-04)We present in-flight performance measurements of the Ionospheric Connection Explorer EUV spectrometer, ICON EUV, a wide field (17 degrees x12 degrees) extreme ultraviolet (EUV) imaging spectrograph designed to observe the ... -
WIP: The Feasibility of High-performance Message Authentication in Automotive Ethernet Networks
(2023-02-27)Modern vehicles are increasingly connected systems that expose a wide variety of security risks to their users. Message authentication prevents entire classes of these attacks, such as message spoofing and electronic control ... -
In Flight Performance of the Far Ultraviolet Instrument (FUV) on ICON
(Springer, 2023-04)The NASA Ionospheric Connection Explorer (ICON) was launched in October 2019 and has been observing the upper atmosphere and ionosphere to understand the sources of their strong variability, to understand the energy and ... -
Phononic Bandgap Programming in Kirigami By Unique Mechanical Input Sequencing
(Wiley, 2023-04)This study investigates the programming of elastic wave propagation bandgaps in periodic and multi-stable metamaterials by intentionally and uniquely sequencing its constitutive mechanical bits. To this end, stretched ... -
Wall-pressure fluctuations in an axisymmetric boundary layer under strong adverse pressure gradient
(Cambridge University Press, 2023-04)Measurements of fluctuating wall pressure in a high-Reynolds-number flow over a body of revolution are described. With a strong axial pressure gradient and moderate lateral curvature, this non-equilibrium flow is relevant ... -
Spectrum of Modularity: An Alaskan Case Study of Modular Housing Types
(2023-08-16)To communicate and utilize research of different options for Alaskan housing, a framework for comparison is necessary. The design work in this document attempts to unify our language and model for approaching modularity ... -
Understanding the Security of Linux eBPF Subsystem
(ACM, 2023-08-24)Linux eBPF allows a userspace application to execute code inside the Linux kernel without modifying the kernel code or inserting a kernel module. An in-kernel eBPF verifier preverifies any untrusted eBPF bytecode before ...
