A Filter-Based Model Of Visual Recognition, Olivia Rose Bockler

Arts & Sciences Graduate Student Theses and Dissertations

Visual recognition, a key perceptual process, enables primates to identify faces, food, tools, and potential threats in their environment. Cortical neurons along the ventral visual stream—spanning from early visual cortex (V1) through inferotemporal cortex (IT), with long-range projections to ventrolateral prefrontal cortex (vlPFC)—are essential for visual recognition. Traditional models propose that neuronal representations increase in complexity in each stage of this pathway, culminating in object-specific representations in higher-order cortex. However, this hypothesis remains debated, particularly as artificial visual models have countered that individual neurons along this pathway may function more as filters contributing to distributed representations of objects. Thus, this …

Brazilian Instrumental Music, U.S. Jazz, And Transnationalism: A Study Of National Identity In The Twentieth Century And Present, Felipe Guz Tinoco

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation considers the relationship between Brazilian instrumental music, U.S. jazz, and Brazilian national identity from the early twentieth century to the present. Though the time frame is broad, the present work uses nationalism as an anchoring point through which I analyze multiple musical genres. Previous works have primarily examined songs and lyrics, particularly during the military dictatorship (1964-85), when words against the regime were censored and songwriters persecuted. However, listeners and musicians of instrumental music also engaged with discourses of national identity in profound terms before, during, and after this period, posing ideals of Brasilidade against cultural productions abroad, …

A Topological Route To Engineering Robust And Bright Supersymmetric Laser Arrays, Soujanya Datta, Mohammad Alizadeh Fard, Ramy El-Ganainy, Krishanu Roychowdhury

Michigan Tech Publications

In recent years, several proposals that leverage principles from condensed matter and high-energy physics for engineering laser arrays have been put forward. The most important among these concepts are topology, which enables the construction of robust zero-mode laser devices, and supersymmetry (SUSY), which holds the potential for achieving phase locking in laser arrays. In this work, we show that the relation between supersymmetric coupled bosonic and fermionic oscillators on one side, and bipartite networks (and hence chiral symmetry) on another side can be exploited together with non-Hermitian engineering for building one- and two-dimensional laser arrays with in-phase synchronization. To demonstrate …

Terrestrial Evidence For Volcanogenic Sulfate-Driven Cooling Event ~30 Ka Before The Cretaceous–Paleogene Mass Extinction: Volcanism-Induced Cooling ~30 Ka Pre-K–Pg Boundary, Lauren O'Connor, Rhodri Jerrett, Gregory Price, Tyler Lyson, Sabine Lengger, Francien Peterse, Bart Van Dongen

School of Geography, Earth and Environmental Sciences

Alongside the Chicxulub meteorite impact, Deccan volcanism is considered a primary trigger for the Cretaceous–Paleogene (K–Pg) mass extinction. Models suggest that volcanic outgassing of carbon and sulfur—potent environmental stressors—drove global temperature change, but the relative timing, duration, and magnitude of such change remains uncertain. Here, we use the organic paleothermometer MBT′5me and the carbon-isotope composition of two K–Pg-spanning lignites from the western Unites States, to test models of volcanogenic air temperature change in the ~100 kyr before the mass extinction. Our records show long-term warming of ~3°C, probably driven by Deccan CO2 emissions, and reveal a transient (<10 kyr) ~5°C cooling event, coinciding with the peak of the Poladpur “pulse” of Deccan eruption ~30 kyr before the K–Pg boundary. This cooling was likely caused by the aerosolization of volcanogenic sulfur. Temperatures returned to pre-event values before the mass extinction, suggesting that, from the terrestrial perspective, volcanogenic climate change was not the primary cause of K–Pg extinction.

Momordicine-I Suppresses Head And Neck Cancer Growth By Modulating Key Metabolic Pathways, Debojyoty Bandyopadhyay, Ellen T Tran, Ruchi A Patel, Matthew A Luetzen, Kevin Cho, Leah P Shriver, Gary J Patti, Mark A Varvares, David A Ford, Kyle S Mccommis, Ratna B Ray

2020-Current year OA Pubs

One of the hallmarks of cancer is metabolic reprogramming which controls cellular homeostasis and therapy resistance. Here, we investigated the effect of momordicine-I (M-I), a key bioactive compound from Momordica charantia (bitter melon), on metabolic pathways in human head and neck cancer (HNC) cells and a mouse HNC tumorigenicity model. We found that M-I treatment on HNC cells significantly reduced the expression of key glycolytic molecules, SLC2A1 (GLUT-1), HK1, PFKP, PDK3, PKM, and LDHA at the mRNA and protein levels. We further observed reduced lactate accumulation, suggesting glycolysis was perturbed in M-I treated HNC cells. Metabolomic analyses confirmed a marked …

Building Evidence-Based Pbs For Schools, Clinics And Communities, Tom Clees

Georgia Association for Positive Behavior Support Conference

Abstract

For students in both the general and adapted curriculum, low achievement, behavioral excesses and social skills deficits are predictive of each other (Gresham, 2016;). Too, an escalating cycle may lead to further antisocial responses, a decrease in learning outcomes, and exclusion from services for some (Kauffman, 2018). Related to these challenges, the successful application of positive behavior supports has been widely reported by schools, clinics, and community-based services. Although definitions of PBS, and the scope of these practices, vary depending on the reference point of those responsible for administration and application, there seems to be agreement that PBS practices …
