Native American Oral Evidence: Finding A New Hearsay Exception, Max Virupaksha Katner
Native American Oral Evidence: Finding A New Hearsay Exception, Max Virupaksha Katner
Tribal Law Journal
The Federal Rules of Evidence hearsay rules unjustifiably exclude legitimate and trustworthy evidence that support many Native American legal claims. Native American communities traditionally were not literate and rarely recorded the treaties, contracts, and other legal instruments they drew up or honored in any kind of written format, oftentimes recording their histories and diplomatic events in other ways; take for example wampum belts used by the Haudenosaunee Confederacy, among others. While the U.S. legal system presupposes that evidence in written statements provides a greater assurance of accuracy and truth than oral statements, this is not always the case. Writing is …
“Preservative Of All Other Rights”: Voting And Social Justice In The Post-Trump Era, Vinay Harpalani
“Preservative Of All Other Rights”: Voting And Social Justice In The Post-Trump Era, Vinay Harpalani
Faculty Scholarship
As social justice advocates rejoice over Donald Trump’s defeat and look for paths forward, the biggest lesson comes from the 2020 presidential election itself. The right to vote is “preservative of all other rights[,]” and this past year underscored its importance more than ever. In the midst of the COVID-19 pandemic, high voter turnout—and especially high Black voter turnout—propelled Joe Biden to victory. Even as the Electoral College and partisan gerrymandering continue to undermine the popular will, America’s changing demographics favor people of color and progressives. Moreover, the elected branches of government have become more significant because Trump packed the …

With the declaration of a worldwide pandemic in March 2020 (World Health Organization 2020), COVID-19 has become a primary focus of governments and public health systems across the world with increases in infection and death rates. By mid-April 2020, more than 80% of countries had imposed containment and mitigation measures. But for developing nations, the threats of this global pandemic are more acute given the lack of resources and the capacity to deal with a shock of this magnitude (Loayza 2020). Despite calling for a lockdown on March 24th, 2020 (Pradhan 2020), Nepal faces several public health challenges including limited …
Neanderthal Ecology In Western Iberia: The Case From Lapa Do Picareiro, Milena Moreira De Carvalho
Neanderthal Ecology In Western Iberia: The Case From Lapa Do Picareiro, Milena Moreira De Carvalho
Anthropology ETDs
In Iberia, potentially the last place where Neanderthals survived, the demographic breakdown of small, loosely connected populations seems to have been a significant driver their demise. Human responses to the climatic fluctuations of the Late Pleistocene, particularly Marine Isotope Stage (MIS) 3, could be an explanation for the decreases in Neanderthal population size during this time; it may be that habitat fragmentation and environmental instability contributed to a demographic breakdown, resulting in small, secluded Neanderthal populations that remained for some time in refugia, even after the arrival of anatomically modern humans in Europe some 40,000 years ago. In this dissertation, …
Aging And Gender In The Tsimane’: Differences In Energy Expenditure, Physical Activity, And Horticultural Work, Daniel Kruse Cummings
Aging And Gender In The Tsimane’: Differences In Energy Expenditure, Physical Activity, And Horticultural Work, Daniel Kruse Cummings
Anthropology ETDs
The purpose of this dissertation is to measure and explain age- and sex-related differences in energy expenditure, physical activity, and patterns of horticultural work, in the Tsimane’, a subsistence forager-horticulturalist population from the Bolivian Amazon. Changes in the way energy is used with advancing age has important implications for the tradeoffs negotiated within the aging body as it partitions increasingly limited energy among competing life functions. It is guided by a theoretical framework which posits the co-evolution of the unique suite of fast and slow human life history traits, cooperative production of resources, and ageand sex-specific schedules of growth, production, …
Unnecessary Burdens To Post-Conviction Dna Testing: New Mexico's Post-Conviction Dna Relief Statute And Suggestions For Improvement, Samantha Catalano
Unnecessary Burdens To Post-Conviction Dna Testing: New Mexico's Post-Conviction Dna Relief Statute And Suggestions For Improvement, Samantha Catalano
Student Published Scholarship
Post-conviction DNA testing is often the last option a convicted person may have to establish that they are not guilty of a crime. New Mexico's post-conviction DNA statute requires convicted persons who seek DNA testing to claim innocence and establish that the identity of the perpetrator was an issue at trial. These requirements are currently included in many state post-conviction DNA statutes; however, some states have amended their statutes to remove these unnecessary requirements. Convicted persons who claimed self-defense, or another affirmative defense may be denied post-conviction DNA testing because of inability to claim "innocence" and because the identity of …
Preserving Due Process: Require The Frye And Daubert Expert Standards In State Gang Cases, Fareed Nassor Hayat
Preserving Due Process: Require The Frye And Daubert Expert Standards In State Gang Cases, Fareed Nassor Hayat
New Mexico Law Review
Police officers are almost universally offered and admitted as experts in gang prosecutions. Without being subjected to the stringent requirements of Frye and Daubert expert standards, criminal Defendants’ due process rights are violated. Once admitted, police officers are permitted to testify to the psychology, customs, motivations, social structures and subjective mental states of individual gang members and gang organizations. Police gang expert testimony should only be admitted after the underlying criminal matter has been proven beyond a reasonable doubt, and even then, only if the police gang expert testimony abides by clearly defined rules of evidence. This article advocates for …

Default Culpability Requirements: The Model Penal Code And Beyond, Scott England
Default Culpability Requirements: The Model Penal Code And Beyond, Scott England
Faculty Scholarship
This Article examines section 2.02(3) of the Model Penal Code, both as proposed by the ALI and as modified by MPC states, and recommends new default culpability rules to replace it.
The Model Penal Code’s default culpability provision, Section 2.02(3), plays a central but often overlooked role in the Code’s celebrated culpability scheme. Section 2.02(3) “reads in” a requirement of recklessness when an offense is silent about the mental state required for an offense element. The provision has profound implications for criminal law because thousands of state offenses fail to prescribe culpability requirements. Without a default culpability rule like Section …

Civil Engineering ETDs
Wireless Smart Sensor (WSS) process field data and inform structural field engineers and owners about the infrastructure health, condition, and safety. Engineers acquire the data and investigate changes on displacements under loads to make informed choices and prioritize decisions concerning maintenance, required repairs, and infrastructure replacements. However, reliable data collection and access to displacement information in the field in real-time under loads remains a challenge. The displacement data provided by the WSS in the field undergoes additional processing, and it is seen at a different location, at the decision-making headquarters. If inspectors were able to observe structural displacements in real-time …
Sybil Defense Using Efficient Resource Burning, Diksha Gupta
Sybil Defense Using Efficient Resource Burning, Diksha Gupta
Computer Science ETDs
In 1993, Dwork and Naor proposed using computational puzzles, a resource burning mechanism, to combat spam email. In the ensuing three decades, resource burning has broadened to include communication capacity, computer memory, and human effort. It has become a well-established tool in distributed security. Due to the cost attached to utilizing resource burning mechanism, these have not been popularized in domains apart from cryptocurrency.
In this dissertation, we design efficient resource burning based Sybil defense techniques for permissionless systems. As a first step, we identify existing resource burning mechanisms in literature in Chapter 2. Additionally, we enumerate numerous open problems …
Intelligent Networks For High Performance Computing, William Whitney Schonbein
Intelligent Networks For High Performance Computing, William Whitney Schonbein
Computer Science ETDs
There exists a resurgence of interest in `smart' network interfaces that can operate on data as it flows through a network. However, while smart capabilities have been expanding, what they can do for high-performance computing (HPC) is not well-understood. In this work, we advance our understanding of the capabilities and contributions of smart network interfaces to HPC. First, we show current offloaded message demultiplexing can mitigate (but not eliminate) overheads incurred by multithreaded communication. Second, we demonstrate current offloaded capabilities can be leveraged to provide Turing complete program execution on the interface. We elaborate with a framework for offloading arbitrary …
Microstructural Constraints On The Nebular And Asteroidal Histories Of Calcium-Aluminum-Rich Inclusions From Cv3 Chondrites, Shaofan Che
Earth and Planetary Sciences ETDs
The petrology and mineralogy of calcium-aluminum-rich inclusions (CAIs) from CV3 carbonaceous chondrites have been investigated using transmission electron microscopy (TEM). The goal of this dissertation is twofold: (1) to gain new insights into the nebular processes, such as vapor-solid reactions, accretion, transport, that are responsible for the formation of non-igneous CAIs, and (2) to better understand the role of fluid in the secondary alteration of CAIs on the CV3 chondrite parent body. This work represents the first systematic microstructural study of CAIs from CV3 chondrites.
Chapter 2 presents the microstructural observations of primary mineralogies of fine-grained, spinel-rich inclusions (FGIs) from …

Copper Electrodeposition In Full Wafer Thickness Through-Silicon Vias, Rebecca P. Schmitt
Chemical and Biological Engineering ETDs
Through-silicon vias (TSVs) are a key interconnect technology for advanced packaging of microelectronic devices, and full wafer thickness TSVs are required for certain microelectromechanical systems (MEMS) applications. In this work, electrolytes containing copper sulfate, an acid, chloride, and Tetronic 701 suppressor were implemented for Cu filling of high aspect ratio (10:1), full wafer thickness TSVs. For each electrolyte system, rotating disk electrode voltammetry was used to identify a voltage range for bottom-up Cu filling in the TSVs. Die level feature filling was performed using voltage ramping, which moved active deposition through the vias to yield void-free Cu features. During voltage-controlled …

This research enables new capabilities in LoRa ad-hoc networks allowing for innovative IoT sensors that were previously infeasible due to energy constraints. This is achieved by investigating adaptive data rate (ADR) techniques, enabling reliable and secure remote firmware updates, improving LoRa authentication, and implementing a …
Numerical Evaluation Of Effective Thermal Response Of Heterogeneous Materials, Kevin W. Irick
Numerical Evaluation Of Effective Thermal Response Of Heterogeneous Materials, Kevin W. Irick
Mechanical Engineering ETDs
Heterogeneity in materials leads to increased complication of physics, at the level or scale where heterogeneity exists, making analysis and material behavior predictions more difficult. As a result of the intricate descriptions or understanding of the physics required to determine the behavior of a heterogenous material or system, practitioners frequently prefer the use of effective properties or responses. This body of work is dedicated to performing computational analyses on the thermal behavior of heterogeneous materials and evaluating the corresponding analyses using formal verification approaches. Custom finite element method code was used for solving the heat equation in a variety of …
Solar Insolation Micro-Forecasts Using Longwave Infrared Sensors And Artificial Intelligence, Anthony R. Menicucci
Solar Insolation Micro-Forecasts Using Longwave Infrared Sensors And Artificial Intelligence, Anthony R. Menicucci
Mechanical Engineering ETDs
Solar Insolation Micro-Forecasts (SIMF) are used by Independent Service Operators (ISOs) and other grid operators to maintain constant and stable electrical grid frequency, voltage, power factor and waveform across their transmission infrastructure. Intermittent, thick, dense and typically cumulus clouds negatively impact the electrical grid by quickly turning on and off power production from large solar photovoltaic (PV) fields, causing grid stability problems between generation and load. Forecasting insolation values over large PV fields allows operators the chance to anticipate and proactively implement mitigation strategies like engaging spinning reserve from gas turbines, deploying generators, buying power in the spot market, and …

Circuit Topology Estimation In An Adaptive Protection Platform, Daniel Ruiz
Electrical and Computer Engineering ETDs
Modern electric power systems, power system protections and controls have experienced a significant change, thanks to the introduction of new technologies, such as microprocessors, GPS, communication, etc. These technologies brought an increased amount of measured-data and information flow on power grids. Adaptive protection systems have been introduced to increase the reliability, selectivity, and sensitivity of the traditional protection systems. An adaptive protection system highly relies on the communication system infrastructure to identify the latest status of power grid (e.g., circuit topology or generation level of distributed energy resources). However, when the communication links to some of the equipment are outaged …

The targeted cognitive radio (CR) has sensing and learning abilities that incorporate advanced signal processing and machine/deep learning (ML/DL) techniques. It can operate over a heterogeneous wideband spectrum that is much wider than the ones proposed in the literature, most likely covering several hundreds of MHz. It has the ability to detect existing signals in the surrounding RF environment and identify their origins. Furthermore, it cognitively uses channel selection, transmit power control and interference cancellation to adapt its communications mode in response to observed …
Niche Dynamics Of The Felid Guild Following The Pleistocene Megafaunal Extinction, Nicholas A. Freymueller
Niche Dynamics Of The Felid Guild Following The Pleistocene Megafaunal Extinction, Nicholas A. Freymueller
Biology ETDs
The loss of large carnivores is fundamentally restructuring modern mammal communities. However, large carnivore removal is not exclusively a modern trend. The Pleistocene Megafaunal Extinction (PME) resulted in a near-eradication of hyper-carnivorous felids such as saber-toothed cats. However, it is unclear if smaller surviving meso-felids began to infill this ecological vacuum post-PME. I apply Ecological Niche Modeling (ENM) to test evaluate whether surviving felids filled in vacant niches post-extinction, and hypothesize that they ought to have shown increased niche-overlap patterns with mega-felids post-extinction. I model species’ fundamental niches using a multi-temporal approach, and develop a novel test to model realized …
Understanding The Role Of Atom Trapping In The Evolution Of Hydrocarbon Transformation Catalyst Morphology, Griffin Alexander Canning
Understanding The Role Of Atom Trapping In The Evolution Of Hydrocarbon Transformation Catalyst Morphology, Griffin Alexander Canning
Chemistry and Chemical Biology ETDs
Converting alkanes to other, more chemically and economically valuable molecules requires catalysts that can survive elevated temperatures and highly reducing environments. These environments can cause many metal-nanoparticle based catalysts to sinter rapidly, causing a loss of activity. They must also tolerate the coke formation, as well, since coke can restrict access to active sites by gas phase molecules, thus lowering catalytic activity. While there are routes to improve both the sinter and coke resistance of catalysts, an alternative strategy is to develop a protocol for regenerating the activity of the catalyst in question when coke formation or sintering becomes problematic. …

Performance Improvements For Next Generation Falling Particle Receiver Systems, Nathan R. Schroeder
Performance Improvements For Next Generation Falling Particle Receiver Systems, Nathan R. Schroeder
Mechanical Engineering ETDs
Falling particle receiver (FPR) systems are a rapidly developing technology for concentrating solar power applications. Solid particles are used as both the heat transfer fluid and thermal energy storage media. Through the direct solar irradiation of the solid particles, flux and temperature limitations of tube-bundle receives can be overcome leading to higher operating temperatures and energy conversion efficiencies. Particle residence time, curtain opacity, and curtain stability affect the performance of FPR designs. As the particles fall through the receiver the curtain accelerates, increasing its transmissivity thus decreasing the amount of energy absorbed. Multistage release trough structures catch and release the …
Theoretical And Experimental Studies Of The Emission Of Electromagnetic Radiation By Superluminal Polarization Currents, Andrea Caroline Schmidt-Zweifel
Theoretical And Experimental Studies Of The Emission Of Electromagnetic Radiation By Superluminal Polarization Currents, Andrea Caroline Schmidt-Zweifel
Electrical and Computer Engineering ETDs
Maxwell’s equations establish that patterns of electric charges and currents can be animated to travel faster than the speed of light in vacuo, c, and that these superluminal distribution patterns emit tightly focused packets of electromagnetic radiation that are fundamentally different from the emissions by previously known sources -- on Earth and in the Universe. This dissertation introduces a practical faster-than-light emitter: The superluminal polarization current antenna. Such devices use a polarization current that travels faster than c to give rise to electromagnetic radiation, a technique known as the vacuum Čerenkov effect. In what is to follow, the theoretical and …
