Beyond Profitable Shifts To Green Energies, Towards Energy Sustainability, Farboud Khatami, Erfan Goharian

Faculty Publications

The traditional carbon-based approach towards sustainability has long caused the concepts of green and sustainable energies to be used interchangeably. Recent studies have tried to advance this archaic view by considering more aspects of sustainability. However, almost all major studies have been concerned with only the economic and environmental aspects of electricity generation, whereas the concept of sustainability is beyond these two criteria. In this paper, we seek to provide a methodology for a more comprehensive definition of electricity generation sustainability based on the lessons learned from previous studies and additional metrics suggested by them. The main characteristics of select …

We report a new measurement of the beam-spin asymmetry, Σ, for the γn → K ⁺ Σ− reaction using quasi-free neutrons in a liquid-deuterium target. The new dataset includes data at previously unmeasured photon energy and angular ranges, thereby providing new constraints on partial wave analyses used to extract properties of the excited nucleon states. The experimental data were obtained using the CEBAF Large Acceptance Spectrometer (CLAS), housed in Hall B of the Thomas Jefferson National Accelerator Facility (JLab). The CLAS detector measured reaction products from a liquid-deuterium target produced by an energy-tagged, linearly polarised photon beam with energies in …

State Estimation—The Role Of Reduced Models, Albert Cohen, Wolfgang Dahmen, Ron Devore

Faculty Publications

The exploration of complex physical or technological processes usually requires exploiting available information from different sources: (i) physical laws often represented as a family of parameter dependent partial differential equations and (ii) data provided by measurement devices or sensors. The amount of sensors is typically limited and data acquisition may be expensive and in some cases even harmful. This article reviews some recent developments for this “small-data” scenario where inversion is strongly aggravated by the typically large parametric dimensionality. The proposed concepts may be viewed as exploring alternatives to Bayesian inversion in favor of more deterministic accuracy quantification related …

Lis1 And Ndel1 Regulate Axonal Trafficking Of Mitochondria In Mature Neurons, Jai P. Pandey, Liang Shi, Remi A. Brebion, Deanna S. Smith

Faculty Publications

Defective mitochondrial dynamics in axons have been linked to both developmental and late-onset neurological disorders. Axonal trafficking is in large part governed by the microtubule motors kinesin-1 and cytoplasmic dynein 1 (dynein). Dynein is the primary retrograde transport motor in axons, and mutations in dynein and many of its regulators also cause neurological diseases. Depletion of LIS1, famous for linking dynein deregulation to lissencephaly (smooth brain), in adult mice leads to severe neurological phenotypes, demonstrating post-developmental roles. LIS1 stimulates retrograde transport of acidic organelles in cultured adult rat dorsal root ganglion (DRG) axons but findings on its role in mitochondrial …

Implementation Of An Automated Grading Tool For Phonetic Transcription Training, Marisha Speights Atkins, Dallin J. Bailey, Cheryl D. Seals

Faculty Publications

Clinical phonetic transcription is regarded as a highly specialised skill requiring hours of practice for mastery. Although this skill is a critical part of students’ clinical preparation to become speech-language pathologists, students often report feeling unprepared to apply the skill in clinical practice. Previous studies suggest that increased opportunities for practice and timely feedback on transcriptions are needed in order to develop skill confidence. However, providing more opportunities for practice can be impeded by the limited resources to manage the grading of additional assignments. The purpose of this study is to show the implementation of a web-based learning management system …

Faster Intercalation Pseudocapacitance Enabled By Adjustable Amorphous Titania Where Tunable Isomorphic Architectures Reveal Accelerated Lithium Diffusivity, Wessel Van Den Bergh, Taylor Larison, Maximilliano Jesus Jara Fornerod, Prof. Stefan Guldin, Morgan Stefik

Faculty Publications

Intercalation pseudocapacitance is a faradaic electrochemical phenomenon with high power and energy densities, combining the attractive features of capacitors and batteries, respectively. Intercalation pseudocapacitive responses exhibit surface-limited kinetics by definition, without restriction from the collective of diffusion-based processes. The surface-limited threshold (SLT) corresponds to the maximum voltage sweep rate (vSLT) exhibiting a predominantly surface-limited current response prior to the onset of diffusion-limitations. Prior studies showed increased lithium diffusivity for amorphous titania compared to anatase. Going beyond prior binary comparisons, here a continuum of amorphous titania configurations were prepared using a series of calcination temperatures to tailor both amorphous …

Maternal Depression Moderated By Family Resources When Children Have Developmental Disabilities., Timothy B. Smith, Terisa P. Gabrielsen

Faculty Publications

Children with developmental disabilities require extensive parental involvement in intervention, but parents with depression may be less able to intervene effectively. We examined prevalence of depression symptoms and predictors among 131 mothers of children with disabilities enrolled in early childhood special education. Participants completed several self-report measures of depression and child and family functioning. Children were directly evaluated using the Battelle Developmental Inventory. One year later, 68 mothers repeated self-report measures. Participants (30%) reported elevated depression symptoms across time. Depression scores were correlated with parental stress and family resources. An interaction between higher maternal depression and higher child functioning with …

Atmospheric Plasma Spraying To Fabricate Metal-Supported Solid Oxide Fuel Cells With Open-Channel Porous Metal Support, Jie Lin, Haixia Li, Wanhua Wang, Peng Qiu, Greg Tao, Kevin Huang, Fanglin Chen

Faculty Publications

Metal-supported solid oxide fuel cells (MS-SOFCs) have been fabricated by applying phase-inversion tape-casting and atmospheric plasma spraying (APS). The effect of the binder amount of the phase-inversion slurries on the microstructure development of the 430L stainless steel metal support was investigated. The pore structures, the viscosity of the slurry, porosity and permeability of the as-prepared metal supports are significantly influenced by the amount of the binder. NiO–scandia-stabilized zirconia (ScSZ) anode, ScSZ electrolyte and La_0.6Sr_0.4Co_0.2Fe0.8O_3−δ (LSCF) cathode layers were consecutively deposited on the metal support with an ideal microstructure by APS process. The effect …

Visual Homing For Robot Teams: Do You See What I See?, Damian Lyons, Noah Petzinger

Faculty Publications

Visual homing is a lightweight approach to visual navigation which does not require GPS. It is very attractive for robot platforms with a low computational capacity. However, a limitation is that the stored home location must be initially within the field of view of the robot. Motivated by the increasing ubiquity of camera information we propose to address this line-of-sight limitation by leveraging camera information from other robots and fixed cameras. To home to a location that is not initially within view, a robot must be able to identify a common visual landmark with another robot that can be used …

Cortical Source Analysis Of Event-Related Potentials: A Developmental Approach, Stefania Conte, John E. Richards

Faculty Publications

Cortical source analysis of electroencephalographic (EEG) signals has become an important tool in the analysis of brain activity. The aim of source analysis is to reconstruct the cortical generators (sources) of the EEG signal recorded on the scalp. The quality of the source reconstruction relies on the accuracy of the forward problem, and consequently the inverse problem. An accurate forward solution is obtained when an appropriate imaging modality (i.e., structural magnetic resonance imaging - MRI) is used to describe the head geometry, precise electrode locations are identified with 3D maps of the sensor positions on the scalp, and realistic conductivity …

Making The Best From A Mess: Mental Health, Misconduct, And The "Insanity Defense" In The Va Disability Compensation System, Caleb R. Stone

Faculty Publications

The disability compensation system implemented by the Department of Veterans Affairs ("VA") is highly technical and complex. Before veterans reach questions concerning entitlement to benefits or the amount of compensation, they must first achieve basic eligibility for VA benefits. That involves receiving a discharge that is "honorable" for VA purposes. For some former servicemembers seeking benefits, using the VA's "insanity defense" to excuse misconduct leading to a less-than-honorable discharge may be the best avenue for obtaining compensation. The VA insanity provision contemplated in 38 U.S.C. s. 5303(b) and defined in 38 C.F.R. s. 3.354 is the only "defense" that allows …

States Can Infringe Upon Your Intellectual Property Rights With Impunity In The Era Of "New Federalism", Homayoon Rafatijo, Dennis D. Crouch

Faculty Publications

Antagonized by half a century of insouciance toward federalism boundaries, the "New Federalism" revival began under Chief Justice Rehnquist. As part of this revival, the Rehnquist Court substantially restrained Congress's authority to regulate commerce, abrogate sovereign immunity, fashion remedies pursuant to Section 5 of the Fourteenth Amendment, and "commandeer" state officials. The New Federalism has continued in the Roberts Court Era, most recently in a case weighing congressionally enacted copyright policy against the sovereignty of individual states to disregard copyright. In Allen v. Cooper, a unanimous Supreme Court held that Congress's express power under Article I is not a …

Before the Perseverance rover landing, the acoustic environment of Mars was unknown. Models predicted that: (1) atmospheric turbulence changes at centimetre scales or smaller at the point where molecular viscosity converts kinetic energy into heat1, (2) the speed of sound varies at the surface with frequency^2,3 and (3) high-frequency waves are strongly attenuated with distance in CO₂ (refs.^2,3,4). However, theoretical models were uncertain because of a lack of experimental data at low pressure and the difficulty to characterize turbulence or attenuation in a closed environment. Here, using Perseverance …

U.S. Abortion Care Providers’ Perspectives On Self-Managed Abortion, Aleta Baldwin, Dana M. Johnson, Kathleen Broussard, Luisa Alejandra Tello-Pérez, Melissa Madera, Carol Ze-Noah, Elisa Padron, Abigail R.A. Aiken

Faculty Publications

State-level restrictions on abortion access may prompt greater numbers of people to self-manage their abortion. The few studies exploring perspectives of providers towards self-managed abortion are focused on physicians and advanced practice clinicians. Little is known about the wider spectrum of abortion care providers who encounter self-managed abortion in their clinic-based work. To gain a deeper understanding of this issue and inform future care delivery, we conducted in-depth interviews with 46 individuals working in a range of positions in 46 abortion clinics across 29 states. Our interpretative analysis resulted in themes shaped by beliefs about safety and autonomy, and a …
