Residential Indoor Air Quality Study – Assessment And Mitigation, Giovanni Cerrato Dec 2023

Residential Indoor Air Quality Study – Assessment And Mitigation, Giovanni Cerrato

Mechanical Engineering Theses

An increased awareness in residential indoor air quality (IAQ) has led to an increase in technologies that assist in improving IAQ. Two such technologies include Electro-static (ES) air cleaners and Photocatalytic Oxidizing (PCO) air cleaners. ES air cleaners remove particulate matter from indoor air, but are known to emit ozone, a contaminant, as a by-product. PCO air cleaners abate gaseous pollutants (i.e., Volatile Organic Compounds, VOCs); however, a lack of testing standards creates confusion about their effectiveness in improving IAQ in a real residential home. On the other hand, environmental variables such as temperature and humidity were found to affect …

Impact Of Irrigation On Vulnerability Of Winter Wheat Under Extreme Climate Change Scenario: A Case Study Of North China Plain, Yulian Gao, Lin Wang, Yaojie Yue

Department of Agricultural and Biological Systems Engineering: Faculty Publications

An inadequate understanding of the impacts of adaptation countermeasures tends to exaggerate the adverse e􀀀ects of climate change on agricultural systems. Motivated by proposing reasonable climate change adaptation countermeasures, the present study applied the EPIC model to quantify the impacts of climate change and irrigation changes with future socioeconomic development on agricultural production. Winter wheat yield losses using dynamic irrigation parameters in the North China Plain (NCP) from 2010 to 2099 under a scenario coupling climate change and future socioeconomic development (RCP8.5-SSP3), and those under an extreme climate change scenario (RCP8.5), were simulated.

Enlightenment Ideals And Belief In Progress In The Run-Up To The Industrial Revolution: A Textual Analysis, Ali Almelhem, Murat Iyigun, Austin Kennedy, Jared Rubin Dec 2023

Enlightenment Ideals And Belief In Progress In The Run-Up To The Industrial Revolution: A Textual Analysis, Ali Almelhem, Murat Iyigun, Austin Kennedy, Jared Rubin

ESI Working Papers

We trace the evolution of the language of science, religion, and political economy in the centuries leading to the British Industrial Revolution. Using textual analysis of 264,443 works printed in England between 1500 and 1900, we test whether British culture manifested a belief in progress associated with science and industry. Our analysis yields three main findings. First, there was a separation in the languages of science and religion beginning in the mid-18th century. Second, volumes using language at the nexus of science and political economy became more progress-oriented during the Enlightenment. Third, volumes using industrial language—especially those at the science-political …

Faculty, Staff and Student Publications

Appendiceal cancer is a rare, orphan disease with no therapies currently approved by the FDA for its treatment. Given the limited data regarding drug efficacy, these tumors have historically been treated with chemotherapy designed for colon cancer. However, an overwhelming body of molecular data has demonstrated that appendiceal adenocarcinoma is a distinct entity with key molecular differences from colon cancer, notably rare APC mutation. Recognizing that APC loss-of-function is thought to contribute to taxane resistance and that taxanes are effective in the treatment of other gastrointestinal tumors, including gastric, esophageal, and small bowel adenocarcinoma, we completed a single-center retrospective study …

Immune checkpoint inhibitors improve survival in patients with mismatch repair deficiency/microsatellite instability-high (MSI-H) colorectal cancer. The recurrence outcomes following discontinuation of immunotherapy after prolonged disease control have not been definitively reported in large series. Records from patients with advanced MSI-H colorectal cancer from The University of Texas - MD Anderson Cancer Center who received immunotherapy between 2014 and 2022 and stopped after prolonged clinical benefit were reviewed. Median progression-free and overall survival were estimated. Associations between the event of recurrence and coexisting mutations (KRAS/NRAS, BRAFV600E), metastatic organ involvement (lung, liver, lymph node, or peritoneum), metastatic timing (synchronous vs. metachronous), prior …


The Representation Of Third-Party Helping Interactions In Infancy, Laura Schlingloff-Nemecz, Denis Tatone, Gergely Csibra Dec 2023

The Representation Of Third-Party Helping Interactions In Infancy, Laura Schlingloff-Nemecz, Denis Tatone, Gergely Csibra

School of Psychology

Despite numerous findings on the sophisticated inferences that human infants draw from observing third-party helping interactions, currently there is no theoretical account of how infants come to understand such events in the first place. After reviewing the available evidence in infants, we describe an account of how human adults understand helping actions. According to this mature concept, helping is a second-order, goal-directed action aiming to increase the utility of another agent (the Helpee) via reducing the cost, or increasing the reward, of the Helpee's own goal-directed action. We then identify the cognitive prerequisites for conceiving helping in this way and …

Immunoproximity Biotinylation Reveals The Axon Initial Segment Proteome, Wei Zhang, Yu Fu, Luxin Peng, Yuki Ogawa, Xiaoyun Ding, Anne Rasband, Xinyue Zhou, Maya Shelly, Matthew N Rasband, Peng Zou

Faculty, Staff and Students Publications

The axon initial segment (AIS) is a specialized neuronal compartment required for action potential generation and neuronal polarity. However, understanding the mechanisms regulating AIS structure and function has been hindered by an incomplete knowledge of its molecular composition. Here, using immuno-proximity biotinylation we further define the AIS proteome and its dynamic changes during neuronal maturation. Among the many AIS proteins identified, we show that SCRIB is highly enriched in the AIS both in vitro and in vivo, and exhibits a periodic architecture like the axonal spectrin-based cytoskeleton. We find that ankyrinG interacts with and recruits SCRIB to the AIS. However, …
