Précis Of The Edge Of Sentience: Risk And Precaution In Humans, Other Animals, And Ai, Jonathan Birch

Animal Sentience

We often face grave practical decisions that seem to hinge on whether a system is sentient. This family of cases includes invertebrate animals, people who are unresponsive after brain injury, fetuses, neural organoids, and now AI technologies. We must decide what to do despite ongoing disagreement about the nature of sentience. In our state of uncertainty, we should pragmatically transform the question from “Is it sentient?” to “Is it a sentience candidate, an investigation priority, or neither?”. When a system is a sentience candidate, it is negligent to fail to consider precautions. We should instead evaluate precautions for their proportionality …

Enl Mutation And Aml: A New Model That Reveals Oncogenic Condensate’S Function In Leukemogenesis, Zhong Fan, Yanan Jiang, Xiaotian Zhang

Faculty, Staff and Student Publications

Precise regulation of gene expression is essential for proper development and the maintenance of homeostasis in organisms. Studies have shown that some transcriptional regulatory proteins influence gene expression through the formation of dynamic, locally concentrated assemblies known as condensates, while dysregulation of transcriptional condensates was associated with several cancers, such as Ewing sarcoma and AML [Wang Y et al. (2023) Nat Chem Biol 19, 1223-1234; Chandra B et al. (2022) Cancer Discov 12, 1152-1169]. Mutations in the histone acetylation "reader" eleven-nineteen-leukemia (ENL) have been shown to form discrete condensates at endogenous genomic targets, but it remains unclear how ENL mutations …

Cord Blood-Derived Ink T Cells As A Platform For Allogeneic Car T Cell Therapy, Maison Grefe, Abel Trujillo-Ocampo, Jelita Clinton, Hong He, Ling Yu, Dan Li, Qing Ma, Elizabeth J Shpall, Jeffrey J Molldrem, Jin S Im

Faculty, Staff and Student Publications

CD1d-restricted invariant Natural Killer (iNK) T cells are a suitable candidate for allogeneic Chimeric Antigen Receptor (CAR) T cell therapy as they do not cause graft-versus-host disease (GvHD) due to the monomorphic nature of CD1d proteins. However, the phenotypic and functional heterogeneity of iNK T cells from adult donors (AD) may lead to the inconstant CAR-iNK T cell products. Cord blood-derived (CB) iNK T cells, in contrast, exhibit inter-donor homogeneity in phenotype including uniform CD4 expression and are enriched in memory iNK T cell populations. Thus, we evaluated the preclinical therapeutic potential of iNK T cells derived from cord blood …

Electrical Characterization Of The Alleged Bio-Memristor Physarum Polycephalum, Markus Schmidt, Günter Seyfried, Uliana Reutina, Zeki Seskir, Eduardo R. Miranda

School of Art, Design and Architecture

This study investigates the potential of the slime mold Physarum polycephalum to function as a bio-memristor. In contrast to earlier reports, our experimental results did not show a significant memristive behavior. Instead, all tested slime molds exhibited elliptical I-V characteristics, attributed to their inherent capacitance. To model this behavior, we developed replacement circuits consisting solely of resistors and capacitors, which accurately reproduced the observed results. While these circuits lack memristive properties, they demonstrate potential utility as sub-circuits in analog applications, such as filters, timing circuits, and phase shift networks. Despite it not being a memristor, P. polycephalum may hold promise …

Women’S Pathways Into Prison: Cycles Of Harm, Hilde Tubex, Natalie Gately

Research outputs 2022 to 2026

Women are a minority of the prison population, however their number is increasing at a faster rate than is the case for men. Interviews with 80 incarcerated women in Western Australian prisons revealed similar pathways commencing with adverse childhood experiences and subsequent areas of deprivation, which reverberated throughout their lives, leading to criminal behavior and imprisonment. Describing these cycles of harm, we argue that, in addressing the increase of women in prison, there is a need to move away from the individual “offender-focused” approach and look at the broader systemic context that lets women down and contributes to their criminalization.

Deep Learning For Precise Mri Segmentation Of Lower-Grade Gliomas, Wusat Ullah, Hamza Naveed, Saalam Ali

Sustainable Machine Intelligence Journal

Brain tumors represent a significant public health issue worldwide, affecting individuals across all age groups and leading to severe neurological and cognitive deficits. Lower-grade gliomas (LGGs), classified by the World Health Organization (WHO) as grade II or III, are characterized by more diffuse infiltration into brain tissue compared to high-grade gliomas but exhibit a slower growth rate. Precise evaluation of tumor resection and detection of residual tumor cells are critical, as incomplete resection is associated with an increased risk of disease recurrence.

Food Finding Ability Does Not Predict Annual Survival In Winter Resident Birds, Aidan Hand

Honors Program: Senior Projects (Public)

Small non-migratory birds in temperate locations face many challenges to survive the winter. They must be able to find enough food, which is in decreased supply, to fuel the energetic demands of staying warm. Prior work has demonstrated that birds show individual variation in their foraging behaviors that could contribute to the discovery of new foraging patches, such as novel environment exploration. A better ability to discover new food sources could increase a bird’s chance of surviving the winter by increasing its access to new food patches. To test this hypothesis, we used radio frequency identification (RFID)-enabled bird feeders to …

Assessment Of Bio-Security Knowledge, Attitude And Hygienic Practices Among Smallholder Chicken Farmers In Southern Mozambique, Noémia André Mugabe, Jamal Kussaga, Abdulsudi Issa-Zacharia

All Rsif Scholars' Publications

The production of broiler chickens in intensive systems struggles to maintain hygiene in production, despite contributing to combating malnutrition, generating employment, and increasing family income, especially in developing countries. Using a structured questionnaire survey, a cross-sectional study was carried out among 395 smallholder farmers to evaluate their knowledge, attitudes, and practices related to farm biosecurity in urban and peri-urban areas of Mozambique and determine the factors affecting KAP (knowledge, attitude, and practice) levels. Data were analyzed using Statistical Package for Social Science (SPSS) (IBM version 27). The findings indicate that education level and training significantly influence (p < 0.001) food safety in terms of biosecurity knowledge, attitudes, and practices. Smallholders who attended food safety training exhibited positive attitudes (95.5%, mean score of 89.71 ± 10.1) in contrast to those who did not participate in training (74.8%, mean score of 79.91 ± 9.68). Additionally, washing hands with soap before and after using the toilet and wearing protective clothing during chicken husbandry were significantly associated with education level (χ² = 15.345, P = 0.018); those with informal education were 34% less likely to have a negative attitude toward food safety compared to those with high education. A significant correlation (p < 0.01) was observed between residence area, training, and biosecurity knowledge, attitude, and practice. Because smallholders lack training, hygiene expertise, and biosecurity practices on their farms, this study concluded that they pose a risk to public health and food safety. To maintain consumer health and guarantee food safety, farmers should properly dispose of waste, including dead chickens, and receive continuous training in excellent biosecurity measures on the farm
