An earlier version of this article (Liu et al., 2022) included private data from the Himalayan-III program which should not have been made public. The authors acknowledge and regret their negligence during the selection of the measurements. The impacted data represent only 2.7% of the total data published in this article, and after review, the authors and the editors agree that this unintentional error has no bearing on the work's scientific conclusions. Therefore, we are retracting the impacted data and have made corrections to remove any Himalayan-III program data from the article's text, figures, and supplemental tables.

Analyzing Google Maps As A Data Source For Urban Research In Dhaka, Xinyi Du

Dissertations and Theses Collection (Open Access)

This paper investigates how mass transit infrastructure shapes urban economic activity by examining the impact of Dhaka's first metro line using novel Google Maps data. Leveraging the opening of Metro Line 6 on December 2022, we employ a difference-in-differences framework to analyze changes in business establishment density around metro stations. Our estimates show that every 1% reduction in distance to the nearest metro station adds, on average, about 0.092–0.111 establishments per 40 m × 40 m grid cell—that is, roughly 57 – 69 additional businesses per square kilometer. The effect is even more pronounced for dining: about 1 – 4 …

Supporting On Their Own Terms: Eu Institutions’ Discourses On Mindanao, Vincent Carlo A. Legara

European Studies Department Faculty Publications

This paper critically examines the nature and dynamics of European Union (EU) engagement in Mindanao. The southern Philippines is historically home to Muslims, with a special region that is the Bangsamoro Autonomous Region of Muslim Mindanao (BARMM), formerly known as the Autonomous Region in Muslim Mindanao, where Muslims compose the majority of the population. Muslim Mindanao gained greater autonomy in 2019 after decades of violent conflict and the persistence of weak democratic institutions. Since the 1970s, Muslim secessionist movements have clashed against government troops for independence. These have contributed to poor human development indicators in Mindanao. The EU, previously the …

Does External Labour Market Activeness Affect Agency Problem?, Yuyun Claudie Huang, Jamie Yixing Tong, Joey W. Yang

Research outputs 2022 to 2026

This study examines the relationship between external labour market and the agency problem. Exploiting the staggered recognition of the Inevitable Disclosure Doctrine (IDD) by US state courts to capture a drop in external labour market activeness, we examine whether and how the activeness of external labour market affects managers' empire building behaviour. We find that in IDD-recognising states, managers are less engaged in empire-building activity, thus reducing agency costs and improving firm performance. The effect is concentrated in managers with heightened career concern where their firms experience higher degrees of financial constraints or operate within an industry of more intense …

Children completed the Serial Reaction Time task, a standard measure of procedural learning, during which they unintentionally learned a sequence of finger movements. Electroencephalography (EEG) was continuously recorded …

Advanced Biodegradable Antimicrobial Coatings By Combining Biopolymers And Natural Antimicrobials For The Active Packaging And Extending The Shelf-Life Of Fish And Other Seafood Products: A Review, Hariharan S. Melarcode, Onur Ertugrul, Paola C. Alzate Calderon, Joseph P. Kerry, Michael A. Morris

Research Outputs: 2025-Present

Fish and other seafood products are an integral and valuable part of human diets. In advanced nations, the transportation of fish and other seafood products to customers requires packaging and display. Due to their intrinsic physicochemical properties, seafood products are particularly susceptible to microbial growth, resulting in shorter shelf lives and higher spoilage rates compared to other animal-derived proteins, such as meat. To prevent microbial spoilage and preserve the freshness and quality of fish and other seafood products, petroleum-based plastic materials are commonly used in combination with packaging technologies, such as vacuum packaging and modified atmosphere packaging. However, as these …

Amyloid Accumulation, Brain Atrophy, And Cognitive Decline In Emergent Alzheimer's Disease, Ying Xia, Pierrick Bourgeat, Vincent Doré, Jurgen Fripp, Yen Ying Lim, Simon M. Laws, Christopher Fowler, Christopher C. Rowe, Colin L. Masters, Elizabeth J. Coulson, Paul Maruff

Research outputs 2022 to 2026

Introduction : Emergent Alzheimer's disease (AD) represents a transitional stage where cognitively unimpaired (CU) individuals exhibit subthreshold but increasing amyloid-β (Aβ) levels. The impact of Aβ accumulation on brain volume loss and cognition during this early stage remains unclear. Methods: This retrospective cohort study analyzed data from 408 CU participants who were initially Aβ− (< 15 Centiloids) and followed for up to 15 years. Changes in basal forebrain and hippocampal volume, along with domain-specific cognitive performance, were compared between those who progressed to Aβ+ (≥20 Centiloids) and those who remained Aβ−. Results: Sixty-five CU participants progressed to Aβ+, indicating emergent AD, and showed faster Aβ accumulation and subtle memory decline. However, no significant differences in rate of BF and hippocampal atrophy were observed between groups. Discussion: The results suggest that during this emergent phase of AD, Aβ accumulation is associated with episodic memory loss, in the absence of detectable accelerated brain atrophy. Highlights: Identified cognitively unimpaired individuals in the emergent stage of Alzheimer's disease (AD). Emergent AD exhibits a greater rate of amyloid-β (Aβ) accumulation. No accelerated volume loss detected in the basal forebrain or hippocampus. Emergent AD is also associated with a subtle decline in memory. Early Aβ accumulation may impair cognitive function before structural atrophy.

The Rising Returns To R&D: Ideas Are Not Getting Harder To Find, Yoshiki Ando, James Bessen, Xiupeng Wang

Research Collection School Of Economics

R&D has grown robustly, yet aggregate productivity growth has stagnated. Is this because “ideas are getting harder to find”? Using microdata from the US Census Bureau this paper estimates R&D effectiveness in the manufacturing sector from 1976 to 2018. We find that the marginal effect of R&D on output and the gross marginal returns to R&D have risen sharply. But rivals’ R&D has also gotten more effective, raising expected obsolescence. But firm productivity growth rises with growth in the R&D stock. Higher obsolescence slows the accumulation of R&D capital, reducing the contribution to productivity growth and shortening innovation lives.

Unraveling Nonperturbative Qcd With Transverse Momentum Hadronic Structures, Tommaso Rainaldi

Physics Theses & Dissertations

The main purpose of this thesis is to investigate the theoretical foundations of the factorization theorems that involve transverse quark and gluon momentum distributions, and to better understand the interface between foundational questions and phenomenological applications. Many of these applications involve using transverse parton momentum dependent (TMD) correlation functions as tools for probing the complex nonperturbative structures of the hadrons.

We first introduce the concepts of collinear and TMD factorization in a toy-model theory and, by leveraging the comparative simplicity of such a model, we test the range of validity and limitations of the factorization approach. At the same time, …

An On-The-Fly Synthesis Framework For Ltl Over Finite Traces, Shengping Xiao, Yongkang Li, Shufang Zhu, Jun Sun, Jianwen Li, Geguang Pu, Moshe Vardi

Research Collection School Of Computing and Information Systems

We present an on-the-fly synthesis framework for Linear Temporal Logic over finite traces (LTLf) based on top-down deterministic automata construction. Existing approaches rely on constructing a complete Deterministic Finite Automaton (DFA) corresponding to the LTLf specification, a process with doubly exponential complexity relative to formula size in the worst case. In this case, the synthesis cannot be conducted until the entire DFA is constructed. This inefficiency is the main bottleneck of existing approaches. To address this challenge, we first present a method for converting LTLf into Transition-based DFA (TDFA) by directly leveraging LTLf semantics, incorporating intermediate results as direct components …

The Aggregate Welfare And Trade Implications Of Contracting Frictions In Global Sourcing, Davin Chor, Lin Ma

Research Collection School Of Economics

How much do contracting frictions between global firms and their suppliers impact country welfare and trade? We answer this by developing a model of global sourcing under partial contractibility, where firm-supplier relationships are exposed to a bilateral holdup problem. Sourcing decisions aggregate into a gravity equation for trade flows by organizational mode (intrafirm vs. arm’s length), which we take to structural estimation. We can then evaluate welfare changes with an extended Arkolakis, Costinot and Rodriguez-Clare (2012) formula that incorporates these contracting frictions. Our counterfactual analysis reveals a sizeable average country welfare gain of 9.2% from eliminating contracting frictions in global …

Renal G Protein-Coupled Estrogen Receptor 1 Regulates The Epithelial Sodium Channel Promoting Natriuresis To A Greater Extent In Females, Victoria L Nasci, Jean C Bopassa, Elena Mironova, Megan Rhoads, Ravneet Singh, Dennis P Buehler, David M Pollock, Oleh M Pochynyuk, James D Stockand, Eman Y Gohar

Faculty, Staff and Student Publications

Hypertension prevalence is lower in women than men. Enhanced renal sodium (Na+) handling in females has been implicated in sex-differences in hypertension. Epithelial Na+ channel (ENaC) is a key contributor to Na+ homeostasis and is regulated by estrogen. Recent evidence suggests G protein-coupled estrogen receptor 1 (GPER1) evokes a female-specific natriuresis that involves endothelin-1 (ET-1). ET-1 has been shown to downregulate ENaC activity, but whether GPER1 regulates ENaC to modulate natriuresis is unknown. We tested the hypothesis that renal GPER1 functionally interacts with ENaC to promote natriuresis in a sex-specific manner. RNAscope confirmed co-expression of GPER1 and ENaC in rat …

Faculty, Staff and Student Publications

Innovative therapies such as thermoembolization are expected to play an important role in improving care for patients with diseases such as hepatocellular carcinoma. Thermoembolization is a minimally invasive strategy that combines thermal ablation and embolization in a single procedure. This approach exploits an exothermic chemical reaction that occurs when an acid chloride is delivered via an endovascular route. However, comprehension of the complexities of the biophysics of thermoembolization is challenging. Mathematical models can aid in understanding such complex processes and assisting clinicians in making informed decisions. In this study, we used a Hagen-Poiseuille 1D blood flow model to predict the …

Spontaneous Tumor Regression And Immunotherapy Response Demonstrate Clonal T-Cell Expansion In Merkel Cell Carcinoma, Patrick Hallaert, John W Roman, Mairead Baker, Natasha T Hill, Jennifer L Marte, James L Gulley, Nicholas Logemann, Courtney W Hudgens, Alexandre Reuben, Isaac Brownell

Faculty, Staff and Student Publications

Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin cancer that is responsive to immune checkpoint inhibitors (ICI). On rare occasion, MCC spontaneously regresses. It is speculated that this regression occurs when biopsy-induced antigen shedding precipitates an immune response. Here, we demonstrate the activation of an adaptive immune response in a patient whose tumor underwent spontaneous regression after biopsy. To evaluate the tumor immune microenvironment during regression, we performed quantitative immunohistochemical analysis and T-cell receptor (TCR) sequencing. Relative to baseline, the regressing tumor showed evidence of an activated cytotoxic T-cell response together with increased TCR clonality, greater representation …

Faculty, Staff and Student Publications

Understanding disease progression and sophisticated tumor ecosystems is imperative for investigating tumorigenesis mechanisms and developing novel prevention strategies. Here, we dissected heterogeneous microenvironments during malignant transitions by leveraging data from 1396 samples spanning 13 major tissues. Within transitional stem-like subpopulations highly enriched in precancers and cancers, we identified 30 recurring cellular states strongly linked to malignancy, including hypoxia and epithelial senescence, revealing a high degree of plasticity in epithelial stem cells. By characterizing dynamics in stem-cell crosstalk with the microenvironment along the pseudotime axis, we found differential roles of ANXA1 at different stages of tumor development. In precancerous stages, reduced …

Understanding Grade 10 Learners’ Mathematics Learning Experiences In Rural Schools: Applying The Self-Determination Theory, Hlamulo Wiseman Mbhiza, Thabisile Nkambule

The Rural Educator

The increasing performative expectation in mathematics continuously positions rural learners in a deficit manner within the education system in post-apartheid South Africa. The often-cited low academic performance of rural learners in mathematics fosters the belief that something is wrong with their mathematical learning abilities. The problem with narrow and often decontextualized perspectives of rural learners is that their interactions with mathematical content are frequently overlooked in education research. The purpose of this study was to critically explore grade 10 rural learners’ mathematics learning experiences. We employed a qualitative descriptive approach within a case study design, using semi-structured individual interviews supported …
