An Introduction To The Geography Of Tourism By Velvet Nelson, William C. Terry Sep 2024

An Introduction To The Geography Of Tourism By Velvet Nelson, William C. Terry

The Geographical Bulletin

Geographers specializing in the study of tourism have long complained about the marginalization of the sub-discipline within the wider scope of geography. Those of us who teach tourism geography recognize tourism as an inherently geographical topic ripe for critical investigation in classrooms. Yet despite the obvious appeal, there have been few texts that attempt a comprehensive overview of tourism geography and none geared directly at an undergraduate audience while also striking the right tone and level of engagement required to fulfill the task. I have personally heretofore eschewed the use of textbooks in teaching tourism geography in part because I …


Improved Monitoring Of Forest Disturbance And Succession Using An Optimized Satellite Image Index, Matthew Klotzbach, Jonathan Thayn Sep 2024

Improved Monitoring Of Forest Disturbance And Succession Using An Optimized Satellite Image Index, Matthew Klotzbach, Jonathan Thayn

The Geographical Bulletin

Landscape- to continental-scale studies of forest disturbance and recovery typically rely on satellite image-based indices of vegetation condition. A recently proposed disturbance index that accentuates patches of disturbed forest has been used to detect fire and insect defoliation scars, but until now it has not been used to assess recovery over time. We used a weighted version of the index to emphasize canopy differences caused by fire while minimizing other differences that may exist in the imagery to monitor succession following the 1988 fires in Yellowstone National Park. Spectral estimates of moisture levels were the most important difference between burned …

Computational Immune Synapse Analysis Reveals T-Cell Interactions In Distinct Tumor Microenvironments., Victor G Wang, Zichao Liu, Jan Martinek, Ali Foroughi Pour, Jie Zhou, Hannah Boruchov, Kelly Ray, Karolina Palucka, Jeffrey Chuang

Faculty Research 2024

The tumor microenvironment (TME) and the cellular interactions within it can be critical to tumor progression and treatment response. Although technologies to generate multiplex images of the TME are advancing, the many ways in which TME imaging data can be mined to elucidate cellular interactions are only beginning to be realized. Here, we present a novel approach for multipronged computational immune synapse analysis (CISA) that reveals T-cell synaptic interactions from multiplex images. CISA enables automated discovery and quantification of immune synapse interactions based on the localization of proteins on cell membranes. We first demonstrate the ability of CISA to detect …

S6k1 Controls Dna Damage Signaling Modulated By The Mrn Complex To Induce Radioresistance In Lung Cancer, Ali Calderon-Aparicio, Jun He, Nicole L. Simone

Department of Radiation Oncology Faculty Papers

Radiation is a mainstay of lung cancer treatment; however, resistance frequently develops. Identifying novel therapeutic targets to increase radiation sensitivity is crucial. S6K1 is a serine/threonine kinase known to regulate protein translation which is associated with radioresistance, but the mechanisms involved are unknown. We proposed to determine whether S6K1 promotes radioresistance by regulating DNA repair in lung cancer. Colony formation, protein expression and proliferation were assessed. S6K1 was modulated pharmacologically by either PF-4708671 or genetically by Crispr-Cas9. Higher radioresistance levels in lung cancer cells were associated with lower phosphoactivation of MRN complex members, a key activator of radiation-induced DNA repair …

Department of Biochemistry and Molecular Biology Faculty Papers

Chemical modifications to mRNA respond dynamically to environmental cues and are important modulators of gene expression. Nanopore direct RNA sequencing has been applied for assessing the presence of pseudouridine (ψ) modifications through basecalling errors and signal analysis. These approaches strongly depend on the sequence context around the modification, and the occupancies derived from these measurements are not quantitative. In this work, we combine direct RNA sequencing of synthetic RNAs bearing site-specific modifications and supervised machine learning models (ModQuant) to achieve near-analytical, site-specific ψ quantification. Our models demonstrate that the ionic current signal features important for accurate ψ classification are sequence …
