Volumetric Wear Analysis Of Polyethylene Orthopedic Liners Using Point Clouds, Gabriel Landi

Dartmouth College Master’s Theses

In vivo wear of ultra-high molecular weight polyethylene (UHMWPE) orthopedic bearings represents a major problem in shoulder and knee arthroplasty, with significant amounts of devices failing due to the complication itself, and even more due to associated reasons for retrieval, including aseptic loosening. However, quantification of UHMWPE wear has largely been limited to linear and in vitro volumetric analyses, obscuring the understanding of the amount of clinically relevant material loss. This study proposes new methods to measure articular, rim, and backside surfaces of retrieved shoulder and knee UHMWPE liners, centered around the coordinate measuring machine (CMM)-based collection of high density …

High Thermoelectric Power Conversion Efficiency Of An Earth-Abundant Janus Silicon Oxy-Sulfide Monolayer: A First-Principles Study, Zakariae Darhi, Mounaim Bencheikh, Ravindra Pandey, Larbi El Farh

Michigan Tech Publications

The tunable properties of Janus monolayers, along with advances in their synthesis, make these low-symmetry materials excellent candidates for thermoelectric power generation. In this study, we systematically investigate the electronic and thermal properties of the Janus silicon oxy-sulfide monolayer. The results based on density functional theory reveal that the monolayer is stable. It exhibits a tunable direct band gap and strong covalent bonding. Its ultralow lattice thermal conductivity (< 0.38 W mK⁻¹ at 300 K) is attributed to the broken phonon selection rule for phonon–phonon scattering and a high level of anharmonicity, as reflected in the large Grüneisen parameter. Furthermore, the inclusion …

Electronic Encyclopedia Of Traditional Medicinal Plants At The Museum Pusaka Nias As Supporting Media For Students’ Plant Awareness, Ester Novi Kurnia Zebua, Siti Zubaidah, Sitoresmi Prabaningtyas

Jurnal Pendidikan: Teori, Penelitian, dan Pengembangan

Low student awareness of the existence, diversity, and importance of plants in daily life—referred to as plant awareness, which includes attention, attitudes, relative interest, and knowledge toward plants—remains a challenge in biology learning, partly due to the limited use of electronic learning media that integrate biodiversity with local wisdom or indigenous knowledge. Traditional medicinal plants from the Museum Pusaka Nias have strong potential as contextual learning resources; however, they have not been optimally developed in electronic form. This study aimed to develop an electronic encyclopedia of Nias traditional medicinal plants for high school biology learning and to examine students' plant …

Timescapes Of The Network Society, Robert Hassan

Fast Capitalism

Since the late ‘70s, the mutually reinforcing interaction between neoliberal economics and the revolution in information and communication technologies (ICTs) has transformed the world in many ways. “Globalization” is what we have come to call this process, and many aspects of its profound effect have been analyzed from a range of perspectives (e.g. Appadurai 1990; Robertson 1993; Omahe 1993; Waters 1995; Bauman 1998; Steger 2003). This paper discusses a central element of this change through globalization that has so far received relatively little attention—our relationship with time and how this is changing, in turn, the nature of power and politics. …

Climate Change Deniers Versus Climate Change Decriers: The Pragmatics Of Climate Defense In The Age Of Disinformation, Timothy W. Luke

Fast Capitalism

Thirty-five years ago, Bill McKibben published his best-selling popular depiction of climate change, The End of Nature. Nearly a decade ago, Naomi Klein's global best-seller This Changes Everything: Capitalism vs. The Climate presented her detailed brief: “thought leaders” must resist and reverse the degradation of Earth's climate in the face of denials that this policy change was impossible. As popular activists, McKibben and Klein both believe “more information leads to good and great change.” This gambit presumes when presented disturbing facts on how and why rising fossil fuel use is degrading the climate, like-minded readers will wisely rise, readily organize …

A Capitalist Stranglehold On “Artificial Intelligence”: A Gallop Through Piracy, Privacy Invasion, Lock-In And A Fever Dream Of Democratisation, Aidan Cornelius-Bell

Fast Capitalism

In this paper, I discuss the emergence of personal computing, the rise of platform-controlled smartphones and tablets, and the recent surge in artificial intelligence technologies. I explore how these technological advancements have often been shaped by the interests of capital, with recent trends towards increased platform lock-in, control, and exploitation of users (workers). I argue that without a strong push for open-source, democratised AI, these technologies risk being used to further the globalised colonial capitalist project. I highlight the potential for open-source hardware and software to counter the proprietary and un-hackable future of AI, offering a radical alternative that empowers …

Molecular Survival Strategies Against Kidney Filtration: Implications For Therapeutic Protein Engineering, William Heaps, Anna Elise Packard, Kristina M. Mccammon, Tyler P. Green, Joseph P. Talley, Bradley C. Bundy, Dennis Della Corte

Faculty Publications

The glomerular filtration barrier poses a significant challenge for circulating proteins, with molecules below ~60–70 kDa facing rapid renal clearance. Endogenous proteins have evolved sophisticated evasion mechanisms including oligomerization, carrier binding, electrostatic repulsion, and FcRn-mediated recycling. Understanding these natural strategies provides blueprints for engineering therapeutic proteins with improved pharmacokinetics. This review examines how endogenous proteins resist filtration, evaluates their application in protein engineering, and discusses clinical translation including established technologies (PEGylation, Fc-fusion) and emerging strategies (albumin-binding domains, glycoengineering). We address critical challenges of balancing half-life extension with tissue penetration, biological activity, and immunogenicity—essential considerations for the rational design of next-generation …

The Coalition For Fairness In Soho And Noho, Inc. V. City Of New York

All Decisions

The Court of Appeals reversed the Appellate Division, upholding the City's 2021 rezoning plan for SoHo/NoHo artist lofts. The plan imposed a one-time fee on landlords for converting Joint Living-Work Quarters for Artists (JLWQA) units to unrestricted residential use. The court held that this fee does not constitute a compensable taking under the Fifth Amendment's Takings Clause. It reasoned that landlords lack a compensable property interest in converting their units to a new, more valuable use, as the fee does not burden their existing property rights or coerce them into relinquishing an interest that the government would otherwise have to …

In recent years, hybrid organic–inorganic metal halides have been at the forefront of materials research. Typically, the functional (e.g., optoelectronic) properties of hybrid halides are derived from the inorganic structural part, whereas the organic structural units can add extra advantages in terms of stability, rigidity, and processability. Here, we report the design, synthesis, and characterization of two new hybrid materials in which the outstanding photophysical properties originate from the organic structural part. The new compounds, (C₁₅H16N)₂CdCl₄ and((Br)C₁₅H₁₅N)₂CdCl₄, have 2D layered Ruddlesden–Popper-type perovskite structures. These hybrids are blue-white …

Faculty Publications

The dusty and molecular torus is an elusive structure surrounding supermassive black holes, yet its importance is unequivocal for understanding feedback and accretion mechanisms. The torus and accretion disk feed the inspiraling gas onto the active nucleus, launching outflows that fundamentally connect the active nucleus’s activity to the host galaxy. In this work, we utilize the aperture-masking interferometric mode onboard the JWST to achieve a resolution of 0.08" at 4.3 μm and bring out the fainter features in the central 10 pc of the Circinus galaxy. We show that most of the dust mass is located along the equatorial …

Power Domination Reconfiguration, B. Bjorkman, C. Bozeman, D. Ferraro, M. Flagg, Cheryl Grood, L. Hogben, B. Jacob, Carolyn Reinhart

Mathematics & Statistics Faculty Works

Reconfiguration examines relationships among solutions to a problem. Power domination models placement of monitoring units that allow monitoring of an entire electrical power network, and information about modifying one monitoring solution to another has applications. The study of token addition and removal and token jumping reconfiguration graphs for power domination is initiated. Some results established here can be extended by applying the methods used for power domination to reconfiguration graphs for other parameters. A universal framework for the study of reconfiguration of parameters that are defined from sets of vertices of a graph and satisfy certain rules is introduced. This …

Are You An Ai Convert Yet?, Essraa Nawar

"At one point that evening, after the conversation had moved from travel to work and then to responsibility, Marium paused and asked me what I did. It was not the transactional question that so often fills conference hallways, asked politely and quickly abandoned, but a genuine inquiry. When I told her that I chair the Artificial Intelligence Committee at Leatherby Libraries at Chapman University, and that my work centers on AI literacy, governance, and institutional decision-making rather than promotion or blind adoption, something subtle changed."
