Recent Advancements In The Characterization Of Archaeological Wood, Amir Ghavidel, Reza Hosseinpourpia, Jianhui Zhou

Michigan Tech Publications

Archeological wood is a vital organic archive, yet its degraded state challenges traditional methods for species identification, provenance resolution, and decay assessment. This review synthesizes state-of-the-art advances—integrating artificial intelligence, isotopic systems, and molecular biology—and proposes a four-tier hierarchical diagnostic framework that moves the field from qualitative description to quantitative, high-resolution analysis. Landmark case studies demonstrate how multi-scalar data fusion provides mechanistic understanding of structural decay inaccessible through conventional approaches.

A Dual-Crosslinked Metallo-Elastomer Platform For Architecture-Directed Vascular Remodeling, Narangerel Gantumur, Shuhao Jiao, Xiaochu Ding, Simon Van Herck, Isabella Frangiosa, Emily Kopchick, Caitlin Maureen Purdy, Ty Walker, Aarati Kharal, Ying Grace Chen

Michigan Tech Publications

The engineering of durable small-diameter vascular grafts remains constrained by the challenge of simultaneously achieving mechanical robustness, controlled degradation, and instructive scaffold architecture. Here, we report a programmable dual-crosslinked metallo-elastomer platform, poly(1,3-propylene itaconate-co-2,2′-bipyridine-5,5′-dicarboxylate-co-succinate-co-sebacate) (M-PBIS), that integrates dynamic metal–ligand coordination with covalent crosslinking to enable orthogonal control over network mechanics, time-dependent viscoelastic behavior, and processability. PBIS polymers were synthesized by modular step-growth polyesterification, allowing independent tuning of backbone composition, bipyridine ligand density for metal coordination, and alkene (C = C) content for covalent crosslinking. This multidimensional design space allowed systematic tuning of tensile elastic modulus (0.06–3.2 MPa), extensibility (53%–491%), toughness (66–1339 …

Histamine–Dao Axis In Migraine: Pathophysiology, Genetic Insights, Clinical Evidence, And Therapeutic Implications, Norhan Bassim Jassim, Abdulkadir M. N. Jassim

Muthanna Medical Journal

Migraine is a common neurological illness marked by recurring headache episodes, followed by other neurological and gastrointestinal symptoms. While the precise pathophysiology of migraine is not fully elucidated, increasing evidence indicates that disruptions in histamine metabolism may significantly contribute to the onset of migraines. Diamine oxidase (DAO) is a crucial enzyme that facilitates the extracellular breakdown of histamine, especially inside the gastrointestinal system. Decreased DAO activity can result in histamine buildup, potentially provoking migraine attacks via the stimulation of the trigeminovascular system and the facilitation of neurogenic inflammation. Recent investigations reveal that a significant percentage of migraine patients demonstrate reduced …

Musical Objects, Territories, And Otherness, Andrew Farrar

LSU Doctoral Dissertations

As the materials that composers work with have become increasingly focused on elements outside traditional pitch relations such as timbre or register, so have their approaches to form. One such stream in modern composition, starting from electronic composers such as Pierre Schaeffer, is the use of ”sound” or ”musical” objects. These materials are marked by their wholistic nature, where qualities such as timbre, density, and con- tour are as important to their identity as pitch relationships. Composers such as Schaeffer, James Tenney, and Denis Smalley have all discussed these sound objects in their writings, though they refer to them under …

Aberrant Ciliogenesis Induced By Enhanced Bmp Signaling Causes Heterotopic Ossification, Hiroyuki Yamaguchi, Jianbo Wang, Fangfang Yan, Jiarui Bi, Radbod Darabi, William R. Lagor, Zhongming Zhao, Aris N. Economides, Yuji Mishina, Yoshihiro Komatsu

Faculty, Staff and Student Publications

Bone morphogenetic protein (BMP) signaling is a principal driver of heterotopic ossification (HO), yet how aberrant BMP activity structurally reprograms cellular signaling machinery to develop HO remains unclear. Here, we identify BMP signaling as a direct upstream regulator of ciliogenesis that coordinates a multi-stage, pro-osteochondrogenic signaling relay during HO. Using a conditional gain-of-function BMP mouse model (Acvr1Q207D/+), we demonstrate that enhanced BMP signaling promotes primary cilium biogenesis and axonemal elongation through canonical Smad1/5/9-dependent transcriptional activation of intraflagellar transport (IFT) Ift20, a core component of the IFT machinery. Rather than operating via a singular downstream cascade, these elongated …

Immuno-Endocrine And Inflammatory Modifications In Human Toxoplasmosis: Diagnostic And Predictive Value Of Progesterone And Prostaglandin, Murtadha Hadi Ajmi

Muthanna Medical Journal

Toxoplasma gondii is one of the world's most common parasitic infections, with well-known effects on the immune system but poorly understood effects on the endocrine system and inflammation. Emerging literature indicates that the parasite alters the hormonal balance of the host, which may play a role in the development of disease, inflammation and poor health outcomes. But the diagnostic and predictive value of these immuno-endocrine changes in human toxoplasmosis remains poorly understood. In this case-control study, 45 patients with toxoplasmosis and 28 healthy controls were enrolled. White blood cell count, packed cell volume, erythrocyte sedimentation rate, progesterone and prostaglandin were …

A Systematic Survey Of Brachyuran Land Crabs In The Online Tropical Aquarium Trade, Ella Xanthe Whitaker, David L. Roberts, John I. Spicer, Lucy Millicent Turner

School of Biological and Marine Sciences

Globally the tropical aquatic aquarium trade is a multi-million-dollar industry. Although marine ornamental fish and invertebrates are the main focus, tropical freshwater ornamental species including invertebrates (classed by the sector as semi-aquatic, such as land crabs) are also traded. Land crabs include both brachyurans (true crabs) and anomurans (false crabs, including hermit crabs). These are sourced from wild populations and/or tank-bred for use as ornamental commodity species. This global trade is unregulated and the full extent of the brachyuran land crab trade is unknown. Land crabs are important ecosystem engineers, and collection for the tropical freshwater/semi-aquatic aquarium industry is believed …

Strategic Leverage Points For Effective Watershed Governance: A Micmac Structural Analysis Approach, Ivan Taslim, Sambas Basuni, Moh. Yanuar Jarwadi Purwanto, I Putu Santikayasa

Journal of Environmental Science and Sustainable Development

Over the past two decades, watershed governance in Indonesia has been challenged by rapid land-use change, fragmented institutions, and limited integration of scientific evidence into policy. Previous studies have primarily evaluated watershed sustainability using hydrological or socio-economic indicators, whereas the structural relationships among governance, socio-economic, and biophysical factors remain insufficiently explored. To address this gap, this study applies the Matrix of Cross-Impact Multiplications Applied to Classification (MICMAC) method to examine direct and indirect relationships among watershed governance factors. A pentahelix stakeholder analysis involving government, academia, non-governmental organizations, media, and industry was conducted to evaluate 37 factors identified through a systematic …

A Categorical Framework For Modeling Genetic Drift, Taylor G. Mendes

Rose-Hulman Undergraduate Mathematics Journal

Genetic drift describes changes in allele frequencies that arise from chance sampling in finite populations. This paper develops a categorical framework for organizing the structural features of drift. Population states are modeled as objects, evolutionary transitions as morphisms, reversible transitions as groupoid morphisms, and structure-preserving comparisons between models as functors. Group actions are used to describe deterministic evolutionary operators such as mutation and selection, while orbits and fixed points identify reachable allele-frequency states and stable absorbing outcomes. Universal properties are then used to describe drift as a coherence condition connecting stochastic transitions with deterministic evolutionary maps. The resulting framework complements …

Warm-Air And Forced-Air Ventilation Drying Of Grass Seeds, Werner Maltry

IGC Proceedings (1977-2023)

For the design of warm-air conveyor driers and of ventilated bins to be used for grass seeds drying, certain parameters of the drying characteristics under varying conditions must be known. Investigations in a climatized cham­ber with seeds from different plant species at varying bulk height, inlet air temperature, and rate of air flow have shown the drying charac­teristics of a layer to be quite similar to those of a single drying crop. The curve of the drying velocity can be approximated by two branches, a first branch with constant drying velocity and a second straight-lined declining branch. The whole oper­ation …

IGC Proceedings (1977-2023)

The effects of closing dates, stocking rates, and nitrogen application on seed and wool production of Demeter tall fescue in South Australia are described. Seed production and gross income were greatest at an intermediate closing date (8 September), at the highest level of nitrogen and highest stocking rate. Late closings (6 October and 3 November) resulted in severe depressions in seed yield and gross incomes. Stocking rates of 15 and 30 sheep/ha caused a similar large reduction in seed yield at late closing dates. The gross value of the extra wool produced from late closing date treat­ments (although up to …
