On The Hamilton-Waterloo Problem With A Single Factor Of 6-Cycles, Zazil Santizo Huerta, Melissa S. Keranen

Michigan Tech Publications

The uniform Hamilton-Waterloo Problem (HWP) asks for a resolvable (CM, CN)decomposition of Kv into α CM-factors and β CN-factors. We denote a solution to the uniform Hamilton-Waterloo problem by HWP(v, M, N, α, β). Our research concentrates on addressing some of the remaining unresolved cases, which pose a significant challenge to generalize. We place a particular emphasis on instances where the gcd(M, N) = {2, 3}, with a specific focus on the parameter M = 6. We introduce modifications to some known structures, and develop new approaches to resolving these outstanding challenges in the construction of uniform 2-factorizations. This innovative …

Reduction-Driven Mobilization Of Structural Fe In Clay Minerals With High Fe Content, Anke Neumann, Luiza Notini, W. A.P.Jeewantha Premaratne, Drew E. Latta, Michelle M. Scherer

Michigan Tech Publications

Clay minerals contain significant amounts of Fe in their alumosilicate framework, and this structural Fe can be reduced and re-oxidized, constituting a potentially renewable source of reduction equivalents in sedimentary environments. However, dissolution and/or clay mineral transformations during microbial Fe reduction contradict this concept. Here, we investigate how Fe reduction and re-oxidation affect the propensity of Fe to be released from the clay mineral structure and use selective sequential extractions in combination with Mössbauer spectroscopy. Negligible amounts of Fe were released in the sequential extraction of high Fe content clay minerals NAu-1 and NAu-2. Once aqueous Fe(II) was added as …

All Decisions

In a post-foreclosure holdover proceeding; the court denied the tenant's motion for pretrial discovery aimed at determining the landlord's status under the Good Cause Eviction Law (GCEL). The tenant sought to discover the landlord's real estate holdings to ascertain if GCEL protections applied. The court ruled that GCEL is inapplicable to holdover proceedings under RPAPL § 713 because such actions presume no landlord-tenant relationship exists; thus eliminating the tenant's "ample need" for disclosure. The landlord's cross-motion to amend the petition to reflect the omission of GCEL language was granted.

Mesenchymal Stem Cell-Derived Extracellular Vesicles: Seeking Into Cell-Free Therapies For Bone-Affected Lysosomal Storage Disorders, Andrés Felipe Leal, Harry Pachajoa, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Lysosomal storage disorders (LSDs) constitute a group of monogenic systemic diseases resulting from deficiencies in specific lysosomal enzymes that cause the intralysosomal accumulation of non- or partially degraded substrates, leading to lysosomal dysfunction. In some cases of LSDs, the bone is more severely affected, thus producing skeletal manifestations in patients. Current therapies, such as enzyme replacement therapy (ERT) and gene therapy (GT), show limited efficacy in correcting skeletal abnormalities. Increasing evidence suggests that microenvironmental disturbances also contribute significantly to disease pathogenesis. Therefore, therapeutic strategies targeting lysosomal dysfunction and microenvironmental dysregulation are needed. Mesenchymal stem-cell-derived extracellular vesicles (MSC-EVs) are emerging as …

The Scylla And Charybdis Of Paternalism And Moral Complicity, J.L.A. Donohue

Philosophy Faculty Publications and Presentations

In some circumstances avoiding complicity seems to require acting paternalistically, while avoiding paternalism seems to require moral complicity in another's wrongful projects. In order to solve the conflict we will need to investigate the concepts of paternalism and moral complicity and, more importantly, our moral interest in them in the first place. Why do the wrongs of paternalism and moral complicity matter to us? And what does this tell us about what it means to set out to treat others well, where that includes both respecting their agency and helping them to act rightly? I will suggest that adopting a …
