On The Failure Mechanisms Of Cr-Coated 316 Stainless Steel In Bending Fatigue Tests, Bin Zhang, Ali Haghshenas, Xiaoman Zhang, Jikui Zhao, S. Shao, M. M. Khonsari, S. Guo, W. J. Meng

Faculty Publications

Fully-reversed cyclic bending tests were conducted on uncoated and Cr-coated 316 stainless steel specimens. At high stresses, the uncoated specimens outperformed the Cr-coated ones, while the trend reversed at low stresses. For Cr-coated specimens subjected to high stress amplitude loading, experimental observations showed crack initiation at the Cr/substrate interface due to shear steps formed from dislocation activities in the substrate—a conclusion supported by accompanying finite element analysis. Interfacial crack initiation was not observed under low stress amplitudes. This difference in fatigue crack initiation mechanisms induced an opposite trend in fatigue life between high and low stress amplitudes.

Belief In Unconscious Repressed Memory Is Widespread: A Comment On Brewin, Li, Ntarantana, Unsworth, And Mcneilis (2019), Henry Otgaar, Jianqin Wang, Mark L. Howe, Scott O. Lilienfeld, Elizabeth F. Loftus, Steven Jay Lynn, Harald Merckelbach, Lawrence Patihis

Faculty Publications

What does believing in repressed memory mean? In a recent article in this journal, Brewin, Li, Ntarantana, Unsworth, and McNeilis (2019, Study 3) argued that when people are asked to indicate their belief in repressed memory, they might actually think of deliberate memory suppression rather than unconscious repressed memory. They further argued that in contrast to belief in unconscious repressed memory, belief in deliberate memory suppression is not scientifically controversial. In this commentary, we show that they are incorrect on both counts. Although Brewin and colleagues surveyed people to indicate their belief in deliberate memory suppression, they neglected to ask …

Geometric Analysis Of The Doppler Frequency For General Non-Stationary 3d Mobile-To-Mobile Channels Based On Prolate Spheroidal Coordinates, Michael Walter, Dmitriy Shutin, Martin Schmidhammer, David W. Matolak, Alenka Zajic

Faculty Publications

—Mobile-to-mobile channels often exhibit time-variant Doppler frequency shifts due to the movement of transmitter and receiver. An accurate description of the Doppler frequency turns out to be very difficult in Cartesian coordinates and any subsequent algebraic analysis of the Doppler frequency is intractable. In contrast to other approaches, we base our investigation on a geometric description of the Doppler frequency with the following three mathematical pillars: prolate spheroidal coordinate system, algebraic curve theory, and differential forms. The prolate spheroidal coordinate system is more appropriate to algebraically investigate the problem. After the transformation into the new coordinate system, the theory of …

Early Breastfeeding Practices Contribute To Exclusive Breastfeeding In Bangladesh, Vietnam And Ethiopia, Phuong Hong Nguyen, Sunny S. Kim, Lan Mai Tran, Purnima Menon, Edward A. Frongillo Jr.

Faculty Publications

Limited evidence exists on the complex relationship among interventions, early initiation of breastfeeding (EIBF), prelacteal feeding and exclusive breastfeeding (EBF). We examined whether early breastfeeding practices are associated with EBF and how much improving EIBF and non-prelacteal feeding contributes to increased prevalence of EBF. Survey data were collected in 2010 and 2014 as part of impact evaluations of Alive & Thrive (A&T) interventions to improve infant and young child feeding (IYCF) practices in Bangladesh, Vietnam and Ethiopia. Multivariable logistic regression analyses were used to examine effects of interventions and early breastfeeding practices on EBF. Structural equation modelling quantified the direct …

Distorted Drug Patents, Erika Lietzan

Faculty Publications

Drug patents are distorted. Unlike most other inventors, drug inventors must complete years of testing to the government’s specifications and seek government approval to commercialize their inventions. All the while, the patent term runs. When a drug inventor finally launches a medicine that embodies the invention, only a fraction of the patent life remains. And yet, conventional wisdom holds — and empirical studies show — that patent life is essential to innovation in the pharmaceutical industry, perhaps more so than any other inventive industry. Congress tried to do something about this in 1984, authorizing the Patent and Trademark Office to …

Preventing Wrongful Conviction Caused By Eyewitness (Mis)Identification: Establishing A Presumption Of Unreliability, Bailey D. Barnes

Faculty Publications

Wrongful convictions are inherently antithetical to a key tenant of the system of criminal justice in the United States, which former Supreme Court Justice George Sutherland shrewdly articulated as to ensure that "guilt shall not escape or innocence suffer." Reaching even further into the foundations of the common law, the great legal commentator William Blackstone stated of wrongful convictions that "the law holds it better that ten guilty persons escape, than that one innocent party suffer." This core principle of American justice was bolstered by the statements of two key Founding Fathers, John Adams and Benjamin Franklin. Adams stated of …

Antitrust Regulation And The Federal-State Balance: Restoring The Original Design, Alan J. Meese

Faculty Publications

The U.S. Constitution divides authority over commerce between states and the national government. Passed in 1890, the Sherman Act (“the Act”) reflects this allocation of power, reaching only those harmful agreements that are “in restraint of... commerce among the several States.” This Article contends that the Supreme Court erred when it radically altered the balance between state and national power over trade restraints in 1948, abruptly abandoning decades of precedent recognizing exclusive state authority over most intrastate restraints. This revised construction of the Act contravened the statute’s apparent meaning, unduly expanded the reach of federal antitrust regulation, and undermined the …

Mormon Women Connected Suffrage Directly To Joseph Smith’S First Vision And The Restoration Of The Gospel: Reflections From The 1920 Relief Society Magazine, Ahsley Anderson Webb, Jay H. Buckley

Faculty Publications

On a cold Thursday in early February 1920, newly enfranchised women from across the nation huddled together in Chicago for a seven-day-long Golden Jubilee. The anticipated passage of the Nineteenth Amendment needed only three more states for ratification, which occurred a few months later. At the same time, women in Utah reflected back half a century to February 12, 1870, when Utah Territory granted women the right to vote. Female Utahns rejoiced with their sisters throughout the United States who anticipated the fruition of universal suffrage. Susa Young Gates, who attended the National American Woman’s Suffrage Association Convention in Chicago, …

Individual Performance And Taking On Firm-Specific Roles: The Case Of Business School Associate Deans, Jeff Dyer, David Kryscynski, Christopher Law, Shad Morris

Faculty Publications

The firm-specific human capital dilemma suggests that firms generally want employees to make firm-specific investments but that employees prefer not to make them. We suggest that individual performance may moderate this dilemma such that the dilemma increases as individual performance increases – i.e. firms may prefer high performers in firm-specific roles while high performers may resist these roles more than their lower performing counterparts. We examine our extended firm-specific human capital theory in a context where the classic firm-specific human capital dilemma likely exists: business academia. Using a unique dataset of 4,164 business school professors from 39 of the top …

Impacts Of Laboratory Vibrations And Laser Flicker Noise On Digital Holography, Douglas E. Thornton, Mark F. Spencer, Christopher A. Rice, Glen P. Perram

Faculty Publications

In this paper, we experimentally demonstrate the impacts of laboratory vibrations and laser flicker noise on digital holography (DH). Specifically, we measure both the vibration efficiency and the coherence efficiency of our DH system at various focal-plane array integration times and path-length differences between the signal and reference. These efficiencies, in practice, contribute to the overall mixing efficiency, which is a measure for how well the detected signal and reference interfere. The results show that when the integration time is ≤1ms, the laboratory vibrations are negligible with a vibration efficiency of 100%; however, when the integration time equals 100 ms, …

United States Department Of Defense (Dod) Real Property Repair, Alterations, Maintenance, And Construction Project Contract Data: 2009–2020, Tyler Stout, Adam Teston, Brent T. Langhals, Justin D. Delorit, Carlton Hendrix, Steven J. Schuldt

Faculty Publications

Nearly one-half of all construction projects exceed planned costs and schedule, globally [1]. Owners and construction managers can analyze historical project performance data to inform cost and schedule overrun risk-reduction strategies. Though, the majority of open-source project datasets are limited by the number of projects, data dimensionality, and location. A significant global customer of the construction industry, the Department of Defense (DoD) maintains a vast database of historical project data that can be used to determine the sources and magnitude of construction schedule and cost overruns for many continental and international locations. The selection of data provided by the authors …

A Fully Quantum Calculation Of Broadening And Shifting Coefficients Of The D1 And D2 Spectral Lines Of Alkali-Metal Atoms Colliding With Noble-Gas Atoms, Robert D. Loper, David E. Weeks

Faculty Publications

We use the Baranger model to compute collisional broadening and shift rates for the D₁ and D₂ spectral lines of M + Ng, where M = K, Rb, Cs and Ng = He, Ne, Ar. Scattering matrix elements are calculated using the channel packet method, and non-adiabatic wavepacket dynamics are determined using the split-operator method together with a unitary transformation between adiabatic and diabatic representations. Scattering phase shift differences are weighted thermally and are integrated over temperatures ranging from 100 K to 800 K. We find that predicted broadening rates compare well with experiment, but shift rates are …

Multimodal Representation Learning And Set Attention For Lwir In-Scene Atmospheric Compensation, Nicholas M. Westing, Kevin C. Gross, Brett J. Borghetti, Christine M. Schubert Kabban, Jacob Martin, Joseph Meola

Faculty Publications

A multimodal generative modeling approach combined with permutation-invariant set attention is investigated in this paper to support long-wave infrared (LWIR) in-scene atmospheric compensation. The generative model can produce realistic atmospheric state vectors (T;H₂O;O₃) and their corresponding transmittance, upwelling radiance, and downwelling radiance (TUD) vectors by sampling a low-dimensional space. Variational loss, LWIR radiative transfer loss and atmospheric state loss constrain the low-dimensional space, resulting in lower reconstruction error compared to standard mean-squared error approaches. A permutation-invariant network predicts the generative model low-dimensional components from in-scene data, allowing for simultaneous estimates of the atmospheric state and TUD …

End-To-End Direct Digital Synthesis Simulation And Mathematical Model To Minimize Quantization Effects Of Digital Signal Generation, Pranav R. Patel, Richard K. Martin

Faculty Publications

Direct digital synthesis (DDS) architectures are becoming more prevalent as modern digital-to-analog converter (DAC) and programmable logic devices evolve to support higher bandwidths. The DDS architecture provides the benefit of digital control but at a cost of generating spurious content in the spectrum. The generated spurious content may cause intermodulation distortion preventing proper demodulation of the received signal. The distortion may also interfere with the neighboring frequency bands. This article presents the various DDS architectures and explores the DDS architecture which provides the most digital reconfigurability with the lowest spurious content. End-to-end analytical equations, numerical and mathematical models are developed …

Covid-19 And The Black Death: Nutrition, Frailty, Inequity, And Mortality, Katherine D. Van Schaik, Sharon Dewitte

Faculty Publications

Introduction: COVID-19 has challenged governments, healthcare systems, and individuals, drawing attention to the limits of modern technology and the extent of social inequity. Such challenges have directed attention to historical epidemics as repositories of data that could contribute to effective public health strategies and prognostic modeling. In light of the well-established correlation between frailty and mortality from COVID-19, this paper investigates the relationship between frailty, inequity, and mortality in the setting of the Black Death of 1346 – 1353, in order to identify trends over time in populations at the greatest risk of mortality during pandemics.

Effects Of Germline And Somatic Events In Candidate Brca-Like Genes On Breast-Tumor Signatures, Weston R. Bodily, Brian H. Shirts, Tom Walsh, Suleyman Gulsuner, Mary-Claire King, Alyssa Parker, Moom Roosan, Stephen R. Piccolo

Faculty Publications

Mutations in BRCA1 and BRCA2 cause deficiencies in homologous recombination repair (HR), resulting in repair of DNA double-strand breaks by the alternative non-homologous end-joining pathway, which is more error prone. HR deficiency of breast tumors is important because it is associated with better responses to platinum salt therapies and PARP inhibitors. Among other consequences of HR deficiency are characteristic somatic-mutation signatures and gene-expression patterns. The term “BRCA-like” (or “BRCAness”) describes tumors that harbor an HR defect but have no detectable germline mutation in BRCA1 or BRCA2. A better understanding of the genes and molecular events associated with tumors being …

A search has been performed for neutrinos from two sources, the hep reaction in the solar pp fusion chain and the νe component of the diffuse supernova neutrino background (DSNB), using the full dataset of the Sudbury Neutrino Observatory with a total exposure of 2.47 kton-years after fiducialization. The hep search is performed using both a single-bin counting analysis and a likelihood fit. We find a best-fit flux that is compatible with solar model predictions while remaining consistent with zero flux, and set a one-sided upper limit of φhep<30×103 cm-2 s-1 [90% credible interval (CI)]. No events are observed in the DSNB search region, and we set an improved upper bound on the νe component of the DSNB flux of φνeDSNB<19 cm-2 s-1 (90% CI) in the energy range 22.9

3d Interdigitated Vertically Aligned Carbon Nanotube Electrodes For Electrochemical Impedimetric Biosensing, Benjamin J. Brownlee, Jonathan C. Claussen, Brian D. Iverson

Faculty Publications

Advances in nanomaterials, combined with electrochemical impedance spectroscopy (EIS), have allowed electrochemical biosensors to have high sensitivity while remaining labe-lfree, enabling the potential for portable diagnosis at the point-of-care. We report porous, 3D vertically aligned carbon nanotube (VACNT) electrodes with underlying chromium electrical leads for impedance-based biosensing. The electrodes are characterized by electrode height (5, 25, and 80 μm), gap width (15 and 25 μm), and geometry (interdigitated and serpentine) using scanning electron microscopy, cyclic voltammetry, and EIS. The protein streptavidin is functionalized onto VACNT electrodes for detection of biotin, as confirmed by fluorescence microscopy. EIS is used to measure …

We present our current best estimate of the plausible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years, with the intention of providing information to facilitate planning for multi-messenger astronomy with gravitational waves. We estimate the sensitivity of the network to transient gravitational-wave signals for the third (O3), fourth (O4) and fifth observing (O5) runs, including the planned upgrades of the Advanced LIGO and Advanced Virgo detectors. We study the capability of the network to determine the sky location of the source for gravitational-wave signals from the inspiral …

How Do Parents Teach Their Children About Work? A Qualitative Exploration Of Household Chores, Employment, And Entrepreneurial Experiences, Christoffer L. Loderup, Joshua E. Timmons, Elisabeth R. Kimball, E. Jeffrey Hill, Loren D. Marks, Ashley B. Lebaron

Faculty Publications

This qualitative study examines the question, “How do parents teach their children about work?” The sample included 90 emerging adult “children” (between 18 and 30 years old), 17 parents, and eight grandparents. It spanned two generations in eleven families, and three generations in five families. Altogether the sample totaled (N = 115). Analyses revealed three major methods for teaching children about work: (1) implementing household chores and allowances, (2) facilitating paid employment, and (3) encouraging entrepreneurial experiences. Through each of these methods, children were taught valuable financial principles. Entrepreneurial experiences specifically taught children to work hard for money, to …
