Bridging Machine Learning And Climate Futures: A Framework For Explainable, Self-Directed (Agentic) Ai Models In Monitoring, Mitigation, And Governance Of Anthropogenic Climate Impacts, Vijayanandh Rajamanickam, Ketaki Kulkarni, Vishwanadham Mandala, Ozgur Kisi

Mansoura Engineering Journal

Environmental and societal damage due to anthropogenic climate change demands detection and mitigation strategies that are both effective and accountable. Machine Learning (ML) appears to offer a powerful set of tools but remains unexploited in these areas. A key barrier remains its poor ability to draw causal inferences about external systems, an essential requirement for meaningful continued monitoring, acting on, and shaping of the climate. Explainable, self-directed learned models operate by attributing environmental changes and deciding how best to model the resulting dynamics—they offer a natural solution. Recent developments in computational ecology, meteorology, and ML are combined to propose a …

Robert Bostwick, Paige Vinson, Omar Moukha-Chafiq, Corinne Augelli-Szafran, Kim M. Keeling, Deeann Wallis, Robert A. Kesterson, Steven M. Rowe, David M. Bedwell

Genetically Engineered Models Core Publications

Nonsense suppression rescues functional protein from mRNAs containing in-frame premature termination codons (PTCs). This approach employs small molecules that promote insertion of tRNAs at a PTC during translation (called “readthrough”), enabling translation to continue past the PTC to generate a full-length, functional protein. Some aminoglycosides such as G418 promote readthrough; however, their long-term use is thwarted by toxicity and modest potency. ELX-02, a novel synthetic aminoglycoside, was developed to have both enhanced readthrough activity and reduced toxicity in mammalian cells compared to traditional aminoglycosides. Recent studies suggest that at safe doses, aminoglycosides like ELX-02 may not possess sufficient efficacy to …

Nitrite Oxidation During Ozonation Revisited: Mechanisms Of Nitration Reactions, Tarek Manasfi, Christoph Dieziger, Simon A. Rath, Daisuke Minakata, Urs Von Gunten

Michigan Tech Publications

The formation of toxicologically relevant nitro compounds has been observed during ozonation of nitrite-containing secondary wastewater effluents, but their formation mechanism remains unknown. To identify key nitrating species, three reaction systems were investigated: ozonation of nitrite (O3/NO2–), peroxynitrite (ONOOH/ONOO–), and hydroxyl radical oxidation of nitrite with γ-radiolysis (γ/NO2–). Nitrite ozonation (O3/NO2–) yielded significant amounts of the nitrating agent nitrogen dioxide •NO2 (9.4% at pH 7 to 22% at pH 12) besides the main product nitrate. No peroxynitrite formation was detected during ozonation of nitrite-containing waters, suggesting that •NO2 is the …

Turkish Journal of Chemistry

This study concerns two Hofmann-type-like clathrates using 4-aminopyridine (4AP) as ligands and the transition metal atoms copper (Cu) and zinc (Zn). These clathrates have the structural features of heteronuclear tetracyanonickelate(II) and contain H2O and 4AP molecules as guest molecules, respectively. These two clathrates were characterized by infrared spectroscopy (IR), elemental analysis, and single crystal X-ray diffraction (SC-XRD) techniques. Based on elemental and spectral data, the structural formulae describing these clathrates were found to be [Cu(II)(4AP)4Ni(μ-CN)2(CN)2]·H2O (1) and [Zn(II)(4AP)4Ni(μ-CN)2(CN)2]·(4AP) (2). In addition, the values of some optical, electronic, and thermochemical properties of the two obtained clathrates calculated with the Gaussian 03 …

Investigating The Role Of Centromere Deletion In Chromosome Segregation, Azait Imtiaz

ETDs from 2020-2029

Centromeres are critical genomic regions responsible for ensuring accurate chromosome segregation during cell division. Disruptions in the structural or functional integrity of centromeric DNA could impair kinetochore assembly, leading to chromosome missegregation and chromosomal instability (CIN), a hallmark of various human diseases, including systemic sclerosis (SSc). This study investigated the contribution of centromeric DNA damage and deletion to CIN and explored potential pathogenic mechanisms relevant to SSc. We utilized hTERT-immortalized fibroblast cell lines (CHON-002 and BJ-5ta) to implement two complementary approaches: (i) treatment with bleomycin, a chemotherapeutic agent known to induce DNA double-strand breaks (DSBs), and (ii) targeted deletion of …
