Dual Beam Frequency Comb Ftir Spectroscopy, Connor Kelly

Electronic Theses and Dissertations, 2020-2023

A visible and Infrared (IR) range dual beam frequency comb Fourier transform spectrometer was developed. Using dual mode-locked Ti:Sapphire lasers a comb-interferogram was generated in the visible range. This spectrum was calculated and used to measure the transmittance of a Nd-doped crystal. The system was further developed to generate an IR interferogram by Difference Frequency Generation (DFG) using a Gallium Selenide (GaSe) crystal placed in the mode-locked pump beam. Numerical work was done to calculate the expected DFG spectrum confirming the necessary IR range can be reached. This has been conducted in support of an IR holographic spectroscopic microscopy spatial …

Understanding The Dietary Behavior Of A 7th - 8th Century Avar Community From Jagodnjak, Croatia Using Stable Isotope Analysis Of Bone Collagen, Marlon Koci

Electronic Theses and Dissertations, 2020-2023

The dietary behavior of past communities is influenced by several factors such as environmental sources, social and economic organization, individual preferences, and physiological needs. Every society has its characteristics and understanding the dietary choices of its individuals expands the knowledge about its lifestyle. Applying biochemical tracers, we can explore the food choices of an Early Medieval Avar community. The Jagodnjak cemetery (n=35) in Croatia is dated to the 7–8th century. Historical and archaeological records are currently limited for Avar populations. Jagodnjak is a transitory community from a period where different historical events shaped the community's way of life. The research …

Enhancement And Evaluation Of Proton Pencil Beam Spot Placement Algorithms, Mahboob Ur Rehman

Electronic Theses and Dissertations, 2020-2023

Intensity modulated proton therapy (IMPT) in the form of pencil beam scanning (PBS) has shown improvement in treatment plan quality as compared to conventional proton and photon-based radiotherapy techniques. However, in IMPT maintaining a sharp lateral dose falloff is crucial for sparing organs at risk (OARs), especially when they are in close proximity to the target volume. The most common approach to improve lateral dose falloff is through the use of physical beam shaping devices, such as brass apertures or collimator-based systems. This work has shown that IMPT can be further improved by implementation of advanced spot placement techniques by …

Generic Design Methodology For Smart Manufacturing Systems From A Practical Perspective, Part I—Digital Triad Concept And Its Application As A System Reference Model, Zhuming Bi, Wen-Jun Zhang, Chong Wu, Chaomin Luo, Lida Xu

Information Technology & Decision Sciences Faculty Publications

Rapidly developed information technologies (IT) have continuously empowered manufacturing systems and accelerated the evolution of manufacturing system paradigms, and smart manufacturing (SM) has become one of the most promising paradigms. The study of SM has attracted a great deal of attention for researchers in academia and practitioners in industry. However, an obvious fact is that people with different backgrounds have different expectations for SM, and this has led to high diversity, ambiguity, and inconsistency in terms of definitions, reference models, performance matrices, and system design methodologies. It has been found that the state of the art SM research is limited …

Laser-Microdrop Interactions In Nanoparticle Deposition On Solid Substrates, Tianyi Li

Electronic Theses and Dissertations, 2020-2023

Nanoparticle suspensions are utilized for depositing thin films on solid substrates by a process called nano electrospray laser deposition. In this research, three deposition methods, contact liquid line laser printing, nano-electrospray laser sintering and evaporative optical Marangoni convection are investigated experimentally and analytically. Thin silver lines are printed on indium tin oxide-coated silicon substrates by dispensing silver nanoparticle suspension with a micropipe of inner diameter 51µm and subsequently sintering the nanoparticles with a CO2 laser beam of Bessel intensity profile. The deposited silver lines of 65µm width and 1µm height have good resistivity which can be used to manufacture silver …

Birth Rights And Birth Wrongs Through A Common Law Lens: Why The No Liability Regime Is Likely To Endure, Richard A. Epstein

Faculty Articles

A saga in four parts: Dov Fox’s recent book, the aptly named Birth Rights and Wrongs, is, as its title suggests, a study of the stark conflicts that arise in the highly contested area of reproductive rights. Fox makes the powerful case that the legal protection of reproductive rights, in all their protean forms, is systematically under-protected relative to two key benchmarks: the standards of ordinary decency, and social expectations. In my view, he has an acute awareness of these failures. But his greatest strength is also his greatest weakness, as he systematically ignores the great successes wrought through the …

The Big Data Regulator, Rebooted: Why And How The Fda Can And Should Disclose Confidential Data On Prescription Drugs, Christopher J. Morten, Amy Kapczynski

Faculty Articles

Medicines and vaccines are complex products, and it is often extraordinarily difficult to know whether they help or hurt. The Food and Drug Administration (FDA) holds an enormous reservoir of data that sheds light on that precise question, yet currently releases only a trickle to researchers, doctors, and patients. Recent examples show that data secrecy can be deadly, and existing laws such as the Freedom of Information Act (FOIA) cannot solve the problem. We present here a wealth of new evidence about the urgency of the problem and argue that the FDA must “reboot” its rules to proactively disclose all …

Racism, Health Equity, And Crisis Standards Of Care In The Covid-19 Pandemic, Charlene Galarneau, Ruqaiijah Yearby

Saint Louis University Journal of Health Law & Policy

Long-standing and deeply embedded institutional racism, notably anti-Black racism in U.S. health care, has provided a solid footing for the health inequities by race evident in the COVID-19 pandemic. Inequities in susceptibility, exposure, infection, hospitalization, and treatment reflect and reinforce this racism and cause incalculable and preventable suffering in and loss of Black lives. This Article identifies multiple expressions of racism evident in the crisis standards of care (CSC) created by states and health care institutions to guide the ethical allocation of scarce critical care resources including ventilators. Contextualized within the broad landscape of health inequities pre-COVID-19 as well as …

Improving Access To Emerging Lifesaving Drugs: Solving The Disclosure Problem Within The Patent Dance, Michael J. Schellhous

Saint Louis University Journal of Health Law & Policy

Biologics are a growing class of pharmaceutical drugs and are associated with a significant portion of major medical breakthroughs over the past fifty years. However, in comparison with traditional small-molecule drugs, biologics are vastly more complex, more difficult to manufacture, and extremely expensive. Congress passed the Biologics Price Competition and Innovation Act (BPCIA) in an effort to increase the availability of biosimilars—the generic versions of biologic drugs—but the BPCIA has been largely ineffective. This is due, in part, to the lack of a standard regarding initial information disclosures required at the outset of the BPCIA process, leading to a cumbersome …

The Validation Of A Portable Functional Nirs System For Assessing Mental Workload, Manob Jyoti Saikia, Walter Besio, Kunal Mankodiya

Electrical, Computer, and Biomedical Engineering Faculty Publications

Portable functional near-infrared spectroscopy (fNIRS) systems have the potential to image the brain in naturalistic settings. Experimental studies are essential to validate such fNIRS systems. Working memory (WM) is a short-term active memory that is associated with the temporary storage and manipulation of information. The prefrontal cortex (PFC) brain area is involved in the processing of WM. We assessed the PFC brain during n-back WM tasks in a group of 25 college students using our laboratory-developed portable fNIRS system, WearLight. We designed an experimental protocol with 32 n-back WM task blocks with four different pseudo-randomized task difficulty levels. The hemodynamic …

Development And Evaluation Of Wound Healing Property Of In-Situ Hydrogel Formulation For Topical Delivery Of Short-Chain Hyaluronic Acid In Dental Use, Porniweat Rosaming

Chulalongkorn University Theses and Dissertations (Chula ETD)

Regeneration of damaged periodontal tissues becomes one of the biggest challenges that is hard to overcome, even without the presence of any pathogens. Tissue engineering was proposed as a possible technique for the lost tissues’ restoration. In this study, methacrylated hyaluronic acid (MeHA) hydrogel was developed with different concentrations of low molecular weight (short-chain) hyaluronic acid to achieve the hydrogels with suitable physical properties and biological properties for dental tissue regeneration. The results revealed that short-chain hyaluronic acid (sHA) could interfere with some behaviors of networking systems; however, overall properties (including gelation time, mechanical properties, swelling and degradation profiles, and …

Attribution Science In Takings Litigation, Daniel J. Metzger

Sabin Center for Climate Change Law

Climate science plays a central role in climate litigation, and cases under the Takings Clause of the United States’ and many state constitutions are no exception. In the climate context, takings cases to date have involved claims that challenge the constitutionality of both adaptation and mitigation measures. For instance, real estate developers have claimed that land use and zoning regulations that seek to reduce exposure to climate change impacts constitute regulatory takings. Property owners have claimed that restrictions on the development of fossil fuel infrastructure upset their investment-backed expectations. And property owners adversely impacted by climate-related flood control measures have …
