Background: The objective of this study was to determine the human papillomavirus (HPV) genotypes of high-risk-other HPV Papanicolaou (Pap) tests and of biopsy tissues from patients with high-grade squamous intraepithelial lesion (HGSIL) or cervical cancer. High-risk-other HPV status was determined with the cobas HPV Test (Roche Diagnostics, North America) that identifies 12 high-risk, non-16/18 HPV genotypes. We hypothesized that we would find genotypes of HPV in our population that are not covered by the 9-valent HPV vaccine. Methods: For this retrospective cohort study, we randomly selected 50 high-risk-other HPV Pap test samples from 2018 from our pathology department registries for …
Consequences Of Local Conspecific Density Effects For Plant Diversity And Community Dynamics, Joseph A. Lamanna, Stefan A. Schnitzer
Consequences Of Local Conspecific Density Effects For Plant Diversity And Community Dynamics, Joseph A. Lamanna, Stefan A. Schnitzer
Biological Sciences Faculty Research and Publications
Conspecific density dependence (CDD) in plant populations is widespread, most likely caused by local-scale biotic interactions, and has potentially important implications for biodiversity, community composition, and ecosystem processes. However, progress in this important area of ecology has been hindered by differing viewpoints on CDD across subfields in ecology, lack of synthesis across CDD-related frameworks, and misunderstandings about how empirical measurements of local CDD fit within the context of broader ecological theories on community assembly and diversity maintenance. Here, we propose a conceptual synthesis of local-scale CDD and its causes, including species-specific antagonistic and mutualistic interactions. First, we compare and clarify …

Materials Science and Engineering Faculty Research & Creative Works
The atomic structures of Zn and Na borophosphate glasses were studied using X-ray and neutron scattering techniques. Peaks assigned to the B−O, P−O, and O−O distances confirm that only BO4 units co-exist with the PO4 tetrahedra. The Zn−O and Na−O coordination numbers are found to be a little larger than four. The narrowest peaks of the Zn−O first-neighbor distances exist for the glasses along a line connecting the Zn (PO3)2 and BPO4 compositions (50 mol% P2O5), which is explained by networks of ZnO4, BO4, and PO …

Ground Vacuum Facility To Simulate Low Earth Orbit Plasma Environment, Emmanuel Kofi Asuako Wie-Addo, Jacob Ortega, Daoru Han
Mechanical and Aerospace Engineering Faculty Research & Creative Works
This paper presents a large vacuum facility (6-ft-diameter, 10-ft-long chamber) equipped with a magnetic filter-type low Earth orbit plasma source. A recommended operating envelope for the plasma source was established through single-point measurements by varying the discharge currents of the plasma source and the gas flow rates. A three-axis translation stage was fabricated and tested with 2D and 3D scans of the simulated plasma environment. The measured plasma density during this study was between 1:63 x 1012 − 3:1 x 1012 m−3 for the electrons and 7:54 x 1012 − 1:82 x 1013 m−3 for the ions, whereas the electron …

Financing Pathways For The Energy Transition: A Regional Approach, Ana M. Camelo Vega
Columbia Center on Sustainable Investment
The success of the global energy transition critically requires a shift from a solely national focus to a regional perspective. Regional cooperation is not just a beneficial opportunity; it is an imperative for the future of sustainable energy. Clean energy solutions are inherently regional, necessitating interconnected systems and collaborative frameworks. This regional focus is essential for addressing the complex challenges of the energy transition, requiring comprehensive engineering, institutional, and financial solutions.
This comprehensive report highlights the crucial financing pathways needed to achieve a successful clean energy transition, focusing on four key regions: Africa, Asia and the Pacific, Latin America and …

Columbia Center on Sustainable Investment
As the global economy transitions to a just, low-emissions, climate-resilient, and nature-positive future, we can expect every sector to transform. However, systemic transformation requires strategic transition planning, effective coordination, and communication across the economy. To facilitate this, governments can play a decisive role by managing change and setting incentives and constraints for private actors. Similarly, private sector actors can enhance their corporate strategies and financing decisions to support this transition. Transition plans serve as a roadmap to transformation by outlining a strategic vision and identifying capital needs, external factors, and dependencies.

Asphalt-Binder Mixtures Evaluated By T1 Nmr Relaxometry, Rebecca M. Herndon, Jay Balasubramanian, Magdy Abdelrahman, Klaus Woelk
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Asphalt pavements make up a majority of the essential transportation systems in the US. Asphalt mixtures age and degrade over time, reducing the pavement performance. Pavement performance critically depends on the aging of asphalt binder. the aging of asphalt binder during construction is traditionally modeled by rolling thin film oven (RTFO) testing, while aging during service life is modeled by pressure aging vessel (PAV) testing. Comparing these models to the aging of binders in actual pavements is limited because, to be used for current testing, binders must be separated from the pavement's aggregate by solvent extraction. Solvent extraction will, at …

Section 9 Of The Canadian Charter & Arbitrary Laws: A Taxonomy, An Organizational Ideal, And A Path Forward, François Tanguay-Renaud
Articles & Book Chapters
One of the conditions for a detention not to be arbitrary under s. 9 of the Canadian Charter of Rights and Freedom is that it must be authorized by a law that is itself not arbitrary. The Supreme Court’s pronouncements about what makes a law arbitrary have been brief, question begging and, at times, conflicting. This article takes stock and proposes a path forward.
First, it reviews the Supreme Court’s case law with the goal of developing a taxonomy of its various accounts of arbitrary laws. It identifies three: a formal account (with a procedural check), a purpose-sensitive account, and …

The Influence Of The Race Of Defendant And The Race Of Victim On Capital Charging And Sentencing In California, Catherine M. Grosso, Jeffrey A. Fagan, Michael Laurence
Faculty Scholarship
The California Racial Justice Act of 2020 recognized racial and ethnic discrimination as a basis for relief in capital cases, expressly permitting several types of statistical evidence to be introduced. This statewide study of the influence of race and ethnicity on the application of capital punishment contributes to this evidence. We draw on data from over 27,000 murder and manslaughter convictions in California state courts between 1978 and 2002. Using multiple methods, we found significant racial and ethnic disparities in charging and sentencing decisions. Controlling for defendant culpability and specific statutory aggravators, we show that Black and Latinx defendants and …

New York Falling Behind In Implementing Bold Climate Law, Michael B. Gerrard

In July 2019, shortly after Gov. Andrew Cuomo signed the Climate Leadership and Community Protection Act (CLCPA), I wrote in an op-ed, “The champagne corks are still popping. But the realization is dawning that implementing the new law will be really, really hard. New York is boldly going where no state has gone before … It will take a great deal of sweat and treasure (no one knows just how much), as well as a continuation of the political will that brought us to this point.”
We still do not know how much sweat and treasure will be required, but …

Going "Beyond" Mere Transformation: Warhol And Reconciliation Of The Derivative Work Right And Fair Use, Shyamkrishna Balganesh, Peter S. Menell
Faculty Scholarship
The Supreme Court’s recent decision in Andy Warhol Foundation for Visual Arts, Inc. v. Goldsmith is a watershed moment in the story of copyright jurisprudence. At its broadest, the decision articulates a unified vision — one that had been dormant in the lower court fair use jurisprudence — about the role of copyright and the manner in which to make sense of its effort to balance exclusivity with its myriad limitations. This Essay focuses on how the Court reconciled the working of the statute’s derivative work right with the breadth and reach of the “transformative use” version of the fair …

The Surprising Survival – So Far – Of The Corporate Contribution Ban, Richard Briffault
Faculty Scholarship
In Citizens United v. Federal Election Commission, the Supreme Court invalidated the longstanding ban on the expenditure of corporate funds in federal election campaigns. In so doing, the Court dismissed outright an argument that had long been the foundation for the restriction of corporate money in election campaigns — that, due to the “substantial aggregations of wealth amassed by the special advantages which go with the corporate form[,]” corporate money poses a distinct threat to the integrity of democracy. Instead, viewing corporations as essentially “associations of citizens,” Citizens United determined that “the First Amendment does not permit Congress to …

The GATT security exceptions were practically in hibernation until recently. The recent WTO disputes panel activity concerning such exceptions is characterized by a standard of review that places the accent on ‘when’ action should be taken and not so much on ‘what’ action should be taken. We see two problems with this construction. First, the ‘when’ might be a function of privileged information that those possessing it might be unwilling to divulge in a transparent manner. Second, national security is an amorphous concept, and unless we disaggregate it, it is impossible to pronounce the appropriateness of measures adopted to pursue …
