Development Of Lead-Free Perovskite Passivated Core/Shell Perovskite Nanocrystals With Enhanced Optoelectronic Properties And Environmental Stability, Hanjie Lin

Dissertations - ALL

All-inorganic lead halide perovskite nanocrystals (NCs) have great optoelectronic properties with promising applications in light-emitting diodes (LEDs), lasers, photodetectors, solar cells, and photocatalysis. However, the applications of perovskite NCs face many challenges, including environmental issues and poor endurability of the perovskite-based devices caused by the intrinsic toxicity of Pb and the poor stabilities of perovskites against moisture, heat and light. To address those issues of the lead halide perovskite NCs, we utilized stable lead-free perovskite as a shell to protect the lead halide perovskite NCs, as well as developed lanthanide ions (Ln3+) doped/based-lead-free perovskite NCs to enhance their optical properties, …

Cultivating Post-Soviet Gardens: Seed Saving And The Household Plot In Rural Tajikistan, Katherine Macdonald

Dissertations - ALL

Over the last five years, local NGOs across Tajikistan have established community-based seed banks to support households cultivating agrobiodiverse kitchen gardens. While social movements to preserve local crop varieties are well-documented in other rural contexts, they are new to Central Asia and had gone without study. This dissertation brings together insights from political ecology, feminist political economy, and critical agrarian studies to explore how and why this effort emerged and what rural women’s participation in it signals about life-making in Tajikistan’s post-Soviet countryside. Drawing on qualitative fieldwork and document analysis, I argue that community-based seed banks are a response to …

Advancing Situation Awareness In Safety-Critical Systems: The Role Of Multi-Modal Wearable Augmented Reality, Jean-Philippe Rancy

The second study explores multi-modal AR’s impact on operator mobility and communication, …

Sparse Recovery Using Scale And Signed Permutation Invariant Functions, Jianqing Jia

Dissertations - ALL

Recovering sparse signals from limited and noisy measurements is an important problem in modern data processing. Traditional methods, which often rely on convex relaxations such as the $\ell_1$ norm, struggle in scenarios with high coherence or large dynamic ranges. A major challenge in these settings is to develop a unified and computationally efficient framework that can accommodate a broad class of sparsity-promoting functions. In this dissertation, we overcome these challenges by introducing a general framework for all scale and signed permutation invariant functions. This dissertation has three main parts. In the first part, we introduce the $(\ell_1/\ell_2)^2$-model for sparse recovery …

The Effect Of Bike Lanes On Commuting Patterns And Non-Commuting Perspectives In Cities, Zhuoran Shang

Dissertations - ALL

This dissertation studies how bike lanes affect cities on commuting and non-commuting margins. The first chapter analyzes the impact of bike lanes on commuting behavior, including mode shares, commuting flows, and travel times. Using data from Seattle spanning 2000 to 2012, this chapter employs several reduced-form estimations. Instrumental variable regressions reveal that the provision of bike lanes reduces car mode shares but does not significantly affect bike mode shares. By introducing a novel treatment variable that captures both the proximity and coverage of bike lanes, I find that bike lanes encourage more people to commute by bike, but also contribute …

Data-Efficient 3d Deep Learning, Minmin Yang

Dissertations - ALL

3D data, whether represented as point clouds, volumetric data or meshes, plays a critical role in domains such as autonomous driving, robotics, and medical imaging. However, the complexity of 3D data acquisition and the high cost of annotation often make it impractical to curate large, fully labeled 3D datasets. Furthermore, the unstructured nature of point clouds and the high dimensionality of volumetric data pose additional challenges for designing effective deep learning models. While existing architectures, like PointNet and DGCNN, have made significant progress in learning directly from raw 3D inputs, they typically rely on data-rich scenarios. This dissertation focuses on …

Past Intrusion Of Circumpolar Deep Water In The Ross Sea: Impacts On The Ancient Ross Ice Shelf, Lucilla Capotondi, Gesine Mollenhauer, Tommaso Tesi, Francesco Muschitiello, Alessio Nogarotto, Jens Hefter, Chiara Pambianco, Simon Belt, Mathia Sabino, Francesca Battaglia, Federico Giglio, Alessio Di Roberto, Enrico Pochini, Andrea Geniram, Ester Colizza, Fiorenza Torricella, Giulia Giorgetti

School of Geography, Earth and Environmental Sciences

The Ross Ice Shelf, Antarctica’s largest by area, may face increased instability under future warming, threatening the Antarctic Ice Sheet. Understanding its past response to climate change is critical for anticipating future sea-level rise. We present a multi-proxy reconstruction of ocean and cryosphere conditions in the Ross Sea over the past 40,000 years. Our data show that warm Circumpolar Deep Water reached the JOIDES Trough in the western Ross Sea shortly after the Last Glacial Maximum, coinciding with the retreat of an ancestral ice shelf. This oceanic warming aligns with a southward shift of both the westerly and easterly wind …

Daily Movement Activities Are Associated With Within-Person Instability Of Cognitive Function In Older Adults: Evidence From An Ambulatory Assessment Study, Chih-Hsiang Yang, Donald Hedeker, Jongwon Lee, Halle Prine, Donna Coffman, Jingkai Wei, Jonathan George Hakun

Faculty Publications

Background and Objectives

Physical inactivity and excessive sedentary time (ST) are associated with poor cognitive health in older adults. However, current literature largely relies on cross-sectional designs or in-lab cognitive assessments, which do not adequately reflect cognitive function in naturalistic settings. Further, existing studies have largely overlooked the variability or the instability in daily cognitive function, which represents a critical marker of cognitive decline. This ambulatory assessment study examined the temporal associations of daily movement behaviors with the mean levels and the variability of cognition among older adults at risk of dementia.

The Synthesis Of A Photo-Affinity Probe Library For The Fatty Acid Amide Proteome And The Endocannabinoid System Within, Robert E. Feeney Iii

USF Tampa Graduate Theses and Dissertations

Fatty acid amides are a large family of endogenous metabolites with significant biological activity, including that of the endocannabinoid system. Currently little is known about how this system of tightly regulated compounds works within humans. This work lays the foundation to explore the structure-activity relationship driving the selectivity of ligand-protein interactions involved with fatty acid amides. A library of activity-based proteomic profiling probes for fatty acid amides has been synthesized to this end. Additionally, progress towards phytocannabinoid probes has been made as well.

Incidental Findings In Female Pelvis Mri Performed For Gynaecological Malignancies, Silvia Bottazzi, Roberta V Ninkova, Luca Russo, Andrea Ponsiglione, Benedetta Gui, Daniela Demundo, Massimo Imbriaco, Aradhana M Venkatesan, Evis Sala, Stephanie Nougaret, Lucia Manganaro, Stefania Rizzo

Faculty, Staff and Student Publications

Incidental findings on female pelvic MRI present diagnostic challenges and may have significant clinical implications. Defined as abnormalities unrelated to the primary imaging indication, these findings have become increasingly prevalent with the expanded use of MRI in gynaecological practice. Standard gynaecological MRI protocols, incorporating T1- and T2-weighted sequences, diffusion-weighted imaging, and contrast-enhanced sequences, facilitate the characterisation of numerous extra-gynaecological abnormalities, ranging from benign to critical lesions. This review proposes a compartment-based approach for identifying extra-gynaecological findings, discussing their imaging characteristics and differential diagnoses. This approach may help radiologists systematically assess incidental findings, potentially improving the recognition of clinically relevant abnormalities …

A Battle Of Armies: Massive Attack Of Natural Enemies To The True Armyworm Mythimna Unipuncta (Haworth, 1809) (Lepidoptera: Noctuidae) In Forage Crops, Armando Falcon-Brindis, Raul T. Villanueva

Insecta Mundi

Understanding the interactions between plant-host-parasitoid plays a major role in insect pest management. Farmers in the southeastern United States rely on pasture systems for cattle milk and beef production, but the benefits of parasitoids and predators on major lepidopteran pests on pasture lands are still overlooked. Here, we aimed to identify and quantify the effect of parasitism on the true armyworm Mythimna unipuncta (Haworth, 1809) (Lepidoptera: Noctuidae) attacking teff grass Eragrostis tef (Zucc.) Trotter (Poaceae) and crabgrass Digitaria sanguinalis (L.) Scop. (Poaceae) in western Kentucky. In early August of 2023, 547 larvae of M. unipuncta were collected from experimental …

Why Deliberate Practice Is Not A Basis For Teacher Expertise, Jim Hordern, Nick Pratt, Peter Kelly, Katherine Evans

School of Law, Humanities and Social Sciences

In this paper we examine the notion of ‘deliberate practice’, which has formed the basis of several teacher education programmes in England and the United States and promises to improve the quality of teaching via highly structured training programmes. We identify early criticisms of deliberate practice and unpack the assumptions embedded in its underpinning thinking. We demonstrate that deliberate practice is insufficient as a basis for teacher expertise as teaching is not a ‘performance profession’, the activities of teachers cannot all be easily or meaningfully decomposed, and the ‘goals’ of teaching are not solely geared towards maximising measurable student attainment. …

Self-Powered Rapid Antigen-Specific T-Cell Response Assay For Mycobacterium Tuberculosis Infections, Bo Ning, Sutapa Chandra, Yongchun Pan, Riti Sharan, Ngan Ha, Sanjay Singh, Alexandra Portillo Varela, Lin Li, Qingli Wu, Alexander Kay, Gugu P Maphalala, Clement Adu-Gyamfi, Santiago Carrero Longlax, Anna M Mandalakas, Smriti Mehra, Christopher J Lyon, Edward A Graviss, Andrew R Dinardo, Tony Hu

Interferon-gamma release assays (IGRAs) that evaluate an individual’s T-cell activation response to Mycobacterium tuberculosis (M.tb)-specific peptides serve an important role in diagnosing tuberculosis (TB). However, there are substantial challenges to the use of IGRAs in resource-limited settings. Further, IGRA diagnostic performance can also be compromised in anergic individuals. Here we describe a microfluidic chip-based antigen-specific T-cell response assay (ASTRA) that automates the detection of M.tb-specific T-cell activation responses to facilitate screening for latent M.tb infection and TB. We observe that ASTRA demonstrates high specificity for M.tb infection in independent patient cohorts. Compared with IGRA, ASTRA shows greater …

Biology Faculty Publications and Presentations

The Northern California Current (NCC) system is a productive coastal ecosystem with a mosaic of temporal and spatial features. The phytoplankton community plays a crucial role in supporting the rich ecosystem and economically important fisheries of the NCC. Our study integrates data across two years (2022-2023) and multiple transects to investigate the community composition of two major phytoplankton groups in the NCC: picocyanobacteria and photosynthetic picoeukaryotes (PPE). The abundances and cell sizes of the phytoplankton were measured using flow cytometry. We found PPE present at similar concentrations in both summer and winter, while picocyanobacteria were much more abundant in the …

Il-7 Armed Binary Car T Cell Strategy To Augment Potency Against Solid Tumors, Alejandro G Torres Chavez, Mary K Mckenna, Anmol Gupta, Neha Daga, Juan Vera, Ann M Leen, Pradip Bajgain

Faculty, Staff and Students Publications

Clinical studies of T cells engineered with chimeric antigen receptor (CAR) targeting CD19 in B-cell malignancies have demonstrated that relapse due to target antigen (CD19) loss or limited CAR T cell persistence is a common occurrence. The possibility of such events is greater in solid tumors, which typically display more heterogeneous antigen expression patterns and are known to directly suppress effector cell proliferation and persistence. T cell engineering strategies to overcome these barriers are being explored. However, strategies to simultaneously address both antigen heterogeneity and T cell longevity, while localizing anti-tumor effects at disease sites, remain limited. In this study …

Keynote 2: The Rebirth Of The Santiago Way As A Model And Parameter For The Creation Of Cultural Itineraries, Paolo Caucci Von Saucken

International Religious Tourism and Pilgrimage Conferences

The revival of pilgrimages to Santiago de Compostela was driven by a complex set of factors that converged and solidified in the second half of the twentieth century. Chief among them was the role of the Catholic Church and the regular celebration of Holy Years, proclaimed whenever July 25th—the feast of the Apostle James—falls on a Sunday. Each occasion, supported by modern and effective means of communication, has served to rekindle and promote the pilgrimage to Compostela. A pivotal moment in this revival was the declaration of Pope John Paul II during the Holy Year of 1982, in which he …

F3) From Religious Sites To Cinematographic Sets. The Symbolism Of Religious Cultural Heritage In The Italian Serie “Lolita Lo Bosco”., Antonietta Ivona, Lucrezia Lopez

International Religious Tourism and Pilgrimage Conferences

Religious cultural heritage is a fundamental pillar of territorial identity, especially in regions with a deep historical heritage such as Apulia, in the South of Italy. In addition, it has historically been a key element in the construction of audiovisual narratives, providing symbolic depth to the stories and enriching their aesthetics. The Italian series Lolita Lo Bosco, A Tv series set in Apulia (Italy), takes advantage of these sacred spaces not only as physical scenarios, but also as vehicles of cultural and symbolic significance, historical memory, traditions and tensions between modernity and cultural heritage.
