Purpose: To compare regional biomechanical and topographic outcomes between transepithelial (Epi-on) and epithelium-off (Epi-off) continuous accelerated corneal cross-linking (ACXL) in keratoconus. Design: A retrospective cohort study. Subjects: Seventy-seven keratoconic eyes were included: 45 with Epi-on ACXL and 32 with Epi-off ACXL. Methods: All eyes underwent ACXL (10 mW/cm ², 7.2 J/cm ²). Pentacam HR and Corvis ST measurements were obtained preoperatively (pre), and at 1 month (pos1m), and 6 months (pos6m) postoperatively. The SSIv2m, M, and J ₀, J ₄₅ were evaluated across central (0–3 mm), paracentral (3–6 mm), and peripheral (6–9 mm) regions. Correlated measurements were …

Using Life-History Information To Identify Management Priorities Within An Emergent Multi-Species Grey Mullet Fishery, Calum J. Pritchard, Ayşegül Tuğçe Han, Andrew Macleod, Rachel M. Turnbull, Jamie Small, Sarah Birchenough, Simon Pengelly, Benjamin J. Ciotti

School of Biological and Marine Sciences

Three grey mullets are native to the United Kingdom: Chelon labrosus, Chelon ramada, and Chelon auratus, for which there is an emergent fishery. These species are managed under a broad grey mullet fishery, but aspects of the life-histories of these populations remain undetermined. The fishery has never been formally assessed. For each species, this research i) investigated their life-history, ii) quantified relative fishing pressure, and iii) investigated their relative vulnerability to overfishing. Grey mullets were collected from commercial fisheries along the southern coast of England. Fish were weighed, measured, and ages were assigned by counting scale annuli. Maturity was determined …

The Treatment Of Digital Assets In Insolvency, Nydia Remolina Leon, Aurelio Gurrea-Martinez, Daniel Liu

Research Collection Yong Pung How School Of Law

This article provides a comprehensive analysis of the treatment of digital assets in insolvency. Given that cryptoassets can be the subject of various transactions—including purchase, sale, custody, and lending—understanding their nature and implications in insolvency is relevant for any firm, not just cryptoexchanges. The article begins by offering a general overview of the world of cryptoassets. It then examines the nature of cryptoassets from accounting, financial, and legal perspectives. While much of the literature on insolvency and cryptoassets has primarily focused on the analysis of whether cryptocurrencies constitute property of the estate, this article explores additional issues, such as the …

From Open Banking To Banking-As-A-Service: Regulatory Challenges In The Evolution Of Financial Intermediation, Nydia Remolina Leon

Research Collection Yong Pung How School Of Law

Over the past decade, financial innovation has moved from open banking, centred on consumer-permissioned data sharing, to banking-as-a-service (BaaS), which modularises core banking functions through application programming interfaces. This shift allows fintechs and non-financial platforms to embed financial products seamlessly, reducing transaction costs and fostering innovation. Yet the 2024 collapse of Synapse in the United States exposed the fragility of this model when intermediaries operate outside robust oversight, leaving consumers without recourse and revealing liability fragmentation and regulatory blind spots. This paper distinguishes BaaS from open banking, open finance, and embedded finance, and maps leading global models – from bank-led …

Visually Guided Foraging In Virtual Worlds: Domain-General Properties Of Search Behaviour, Sarah Salo, Alastair Smith

School of Psychology

Everyday human behaviour involves economically driven search for visually relevant targets in complex three-dimensional environments. However, psychological research has typically examined visual search and foraging mechanisms separately, with insights into search emphasising attentional efficiency, and accounts of foraging highlighting decision-making and cognitive control. In order to more closely examine the interrelation between these processes in fully motile environmental search, we devised a novel virtual reality paradigm that required participants to physically explore a large-scale 3D environment and collect multiple visually defined targets. The search environment was organised in patches, with search arrays presented across multiple tables. In single feature search, …

Department of Pediatrics Faculty Papers

OBJECTIVE: Single-session interventions (SSIs) are an innovative, scalable approach for addressing the unmet behavioral and mental health needs of pediatric patients and their families. Specifically, digital SSIs, which are self-guided and delivered online, offer a low-cost and accessible approach but are currently underutilized in pediatric psychology.

METHODS: This topical review aims to describe SSIs broadly and the specific need for digital SSIs, explore potential applications within pediatric psychology, outline future directions and considerations, and present two examples of community-engaged digital SSI design.

RESULTS: SSIs evidence small to medium effects across a range of mental health concerns, including distress, anxiety, and …

Recompression Improves Release Success In Pollack (Pollachius Pollachius): A Step Towards Assessing Post Release Mortality In A Recreational Fishery, T. Stamp, R. Mawer, R. Conlon, A. E. Hall, P. Davies, R. Nesbit, D. Uren, T. Morris, S. Sullivan, S. Thomas, B. D. Stewart, H. Rudd, K. Hyder, T. Osmond, S. Reynell, E. V. Sheehan

School of Biological and Marine Sciences

The recreational fishery for pollack (Pollachius pollachius) in the northeast Atlantic is impacted by the species' high sensitivity to barotrauma. When captured at depth and brought to the surface, gas expansion within the peritoneal cavity can cause a variety of injuries and hinder release. Via an experimental weighted cage, this study evaluated the efficacy of releasing Pollack at depth as a barotrauma mitigation strategy. We found that depth-release significantly increased the probability of released Pollack displaying an active escape response to 83%, compared to 56% for surface-released fish; however, increased capture depth and fish size negatively affected success. Camera observations …

Decidability Of The Orbit Problem Over Q(X), Joshua Holden, Alexa Renner

Mathematical Sciences Technical Reports (MSTR)

The orbit problem is the problem of whether, given x, y ∈ Qn and an n × n matrix A, there exists an i ∈ N such that Aix = y. In 1980, Kannan and Lipton proved that the orbit problem is decidable. We show that a generalization of the orbit problem, where the field is Q(X) for X a countable set of transcendentals, is also decidable. We define the orbit power problem for an arbitrary group G to be the problem of when, given x, y ∈ G, there exists an n ∈ Z such that xn = y. …

Validated Crispr/Cas9 Guide Rnas Targeting Neurodevelopmental Genes In The Tunicate Ciona Robusta, Sydney Popsuj, Tenzin Kalsang, Eduardo D. Gigante

Faculty Articles

The tunicate Ciona robusta provides a powerful and simplified model for dissecting the genetic control of developmental and cell biology. With a larval CNS composed of just over 200 neurons and sensory cells, it has also emerged as a model organism for neurobiology and the development of the nervous system. Although CRISPR/ Cas9-mediated mutagenesis is now routinely used in Ciona as an important technique used to interrogate gene function in diverse biological processes, validated single-guide RNAs (sgRNAs) have yet to be validated for several key neural genes. Here, we report the design and experimental validation of 25 novel sgRNAs targeting …

Bank Competition Amid Digital Disruption: Implications For Financial Inclusion, Erica Xuewei Jiang, Gloria Yang Yu, Jinyuan Zhang

Research Collection Lee Kong Chian School Of Business

We examine how digital disruption affects bank competition using the staggered rollout of 3G mobile networks. 3G expansion increased mobile banking adoption among tech-savvy households, reducing branch networks—especially in younger counties. Banks' strategies diverged: Less branch-reliant banks closed branches and competed on price, while more branch-reliant banks maintained branches but raised spreads. A structural model shows that perceived digital service improvements among younger consumers drove these shifts, reducing welfare for older savers. Counterfactuals demonstrate that subsidizing adoption for older savers can cost-effectively reduce these disparities, facilitating a smoother digital transition.

Pelagic Ecosystem Interactions Of An Offshore Longline Mussel Farm, Llucia Mascorda-Cabre, Philip Hosegood, Martin Attrill, Emma Sheehan

School of Biological and Marine Sciences

Long-term interactions of the UK's first large scale offshore mussel farm with the surrounding pelagic environment were studied to assess the farm's ecological impact. Pelagic fishes, zooplankton community and oceanographic parameters such as temperature, salinity, density, chlorophyll- α, dissolved oxygen and CDOM were quantified over seven years. Effects to oceanographic parameters were observed locally comparing samples collected on the east and west parts of the farm, evidencing turbulent mixing of the water column enhanced by the farm. There was no difference between zooplankton assemblage composition inside and outside the farm, only naturally occurring temporal changes were detected, supporting the hypothesis …

Dynamics Of High-Growth Young Firms And The Role Of Venture Capitalists, Yoshiki Ando

Research Collection School Of Economics

Motivated by the substantial growth and upfront investments of venture capital (VC)-backed firms observed in administrative US Census data, this study develops a life-cycle firm dynamics model. In the model, startups choose the source of financing from VC, angel investors, or banks, depending on their growth potential, and invest in innovation. The calibrated model explains the life-cycle dynamics of firms with different sources of financing and suggests that venture capitalists' managerial advice accounts for around 22% of the growth in VC-backed firms. A counterfactual economy without VC financing would experience an aggregate consumption loss of around 0.46%.

Semiparametric Cointegrating Rank Selection For Curved Cross-Section Time Series, Peter C. B. Phillips

Research Collection School Of Economics

Cointegrating rank selection is studied in a function space reduced rank regression where the data are time series of cross-section curves. Consistent cointegrating rank estimation is developed using information criteria extended to curve time series environments. The asymptotic theory involves two-parameter Gaussian processes that generalise the standard limit processes involved in cointegrating regressions. Simulations provide evidence of the effectiveness of consistent rank selection by the BIC criterion and the tendency of AIC to overestimate order as in standard lag order selection in autoregression, as well as in reduced rank regression with multiple time series.

Singapore In Global Value Chains: Implications Of The Trump Ii Tariffs, Pao-Li Chang, Ruoqing Chen

Research Collection School Of Economics

This paper examines Singapore’s structural position in global value chains (GVCs) and the implications of the second Trump administration’s tariff escalation for Singapore and the broader ASEAN region. We proceed in three parts. First, using the ADB Multi-Regional Input–Output (MRIO) tables for 2019 and 2024, we characterise Singapore’s GVC participation and position. Singapore is the most GVCintensive economy in ASEAN, with nearly half of its gross exports comprising foreign value-added and a markedly downstream orientation. China is its dominant upstream partner across manufacturing and services—intermediating over 27% of foreign content in electronics and over 10% in chemicals—while Malaysia, Taiwan, and …

Marital Stability And Intrahousehold Inequality, Tomoki Fujii, Xirong Lin, Jacob Penglase

Research Collection School Of Economics

We study what predicts marital instability using a unique dataset from Japan with detailed measures of spouses’ consumption, savings, labor supply, satisfaction, and marriage-market conditions. We combine descriptive survival and event-study analyses with several econometric and machine-learning approaches, including Cox proportional-hazards models and DynForest, a method designed for survival data with time-varying covariates. Across these approaches, match quality, household resources, time use, stated satisfaction, and marriage-market conditions all contain predictive information. Our main contribution is to show that intrahousehold consumption allocation matters, highlighting information that is missed by standard demographic, time use, and income measures. We relate these findings to …

The Interplay Of Interdependence And Correlation In Bilateral Trade, Takashi Kunimoto, Cuiling Zhang

Research Collection School Of Economics

Following Crémer and McLean (1985, 1988) for finite type spaces and McAfee and Reny (1992) for continuous ones, we establish two respective sufficient conditions for the existence of efficient, ex ante budget-balanced mechanisms satisfying Bayesian incentive compatibility (BIC) and interim individual rationality (IIR) in bilateral trade settings with interdependent values and correlated beliefs. We then utilize the ex ante welfare (EAW) condition proposed by Kunimoto and Zhang (2026), which is necessary for the stricter requirement of ex post budget balance. We prove that while the EAW condition is sufficient in a two-type model and generalizes existing conditions in the literature, …

How Followers Respond To Leader Differentiation: The Importance Of Considering All Leader Differentiation Properties, Yuchuan Liu, Gary John Greguras

Research Collection Lee Kong Chian School Of Business

A central tenet of many leadership theories is that leaders treat their followers differently. Although leader differentiation is ubiquitous, its effects on leaders and followers are not well understood and theory and research have not simultaneously considered its three key properties: Leader–member exchange (LMX) differentiation, LMX quality, and LMX social comparison. We developed a theoretical model in which these three properties interact to influence followers’ supervisory interactional justice perceptions and subsequently their supervisor-directed deviance and supervisor-directed organizational citizenship behaviors (OCBs). To test our model, we conducted a pre-registered experiment (Study 1), a single-level, multi-wave study (Study 2), and a multilevel, …

Connectivity And Selective Rural Migration, Lin Ma, Yuan Mei, Qunfeng Wu, Mingzhi Xu

Research Collection School Of Economics

How does infrastructure shape rural development? Using household panel data from a nationally representative sample of Chinese villages, matched to high-resolution highway maps, we find that road expansion between 2000 and 2015 operates mainly through reallocation, with less productive farmers scaling down or exiting and more productive farmers remaining and expanding. We quantify the aggregate and distributional consequences in a dynamic spatial equilibrium model with heterogeneous households and endogenous migration. Improved connectivity not only accelerates urbanization but also increases aggregate rural output by 2.2%–5.3% in the long run, even as the rural workforce declines.

The Role Of Local Winds And A Semi-Persistent Coastal Front On The Diurnal Heat Budget In An Upwelling Bay, April P. Thibodeau, Ryan K. Walter, Piero L.F. Mazzini, Thomas P. Connolly, Christopher A. Edwards, Ian Robbins

Faculty Research, Scholarly, and Creative Activity

Coastal embayments in nearshore upwelling systems (“upwelling bays”) play a disproportionately large role in regional oceanography. In these systems, local diurnal wind forcing and thermal gradients associated with an upwelling shadow front that forms between warmer sheltered waters inside the bay and colder recently upwelled waters outside the bay strongly influence local temperature dynamics. Despite their importance to local ecosystems, there are no long-term studies that assess the heat budget inside upwelling bays. In this study, we analyzed approximately two years of water temperature throughout the water column using an autonomous profiler in a small upwelling bay in central California …

The Use Of Foamed Glass Aggregate (Fga) As A Lightweight Fill Above Culverts, Amr Morsy

Mineta Transportation Institute

Transportation infrastructure—including buried utilities, drainage systems, and culverts—is frequently subjected to significant external stresses arising from existing conditions and new construction, especially in urban environments where deformation and failures can lead to significant operational and safety consequences. Lightweight fills offer a viable strategy to mitigate these stresses by reducing imposed loads. This study investigates the use of lightweight fills, specifically Foamed Glass Aggregate (FGA), as a sustainable solution to support California Senate Bill 1 (SB1) efforts to repair and maintain culverts, as well as for new construction applications. A numerical investigation was conducted to evaluate the performance of culverts backfilled …

Casual Killing In The Home: Ecological Citizenship And The Micro-Geopolitics Of Mosquito Cohabitation, Orlando Woods, Junxi Qian

Research Collection College of Integrative Studies

This article explores how the visceral acts of being bitten by and killing mosquitoes can underpin the formation of ecological citizenship. This form of citizenship is premised on human-nature entanglement and raises questions concerning how the rights and responsibilities stemming from such entanglement become distributed across the public and private domains. As a space in which mosquito cohabitation is contested daily, the home is a key site through which ecological citizenship can be forged and theoretical debates concerning urban political ecology can be extended. Human-mosquito entanglements in the home can reveal the limits of public pest management strategies, the partiality …

Extravascular Factor Ix: A Semicentennial Narrative Review, Tvisha Subhasish, Christopher R. Reed

Student Publications

Coagulation factor IX (FIX) is a serine protease that is crucial for normal hemostasis in vertebrates. Unlike other soluble vitamin K-dependent procoagulant enzymes, there is an “extravascular reservoir” of FIX in various tissues. The extravasation of FIX and its subsequent maintenance outside of circulation have long been attributed to its ability to bind collagen IV. This property is conferred by a short, specialized region of its phospholipid-binding gamma-carboxyglutamic acid (Gla) domain. Collagen IV is a nonfibrillar extracellular protein found primarily in basement membranes that assembles into sheet-like supportive structures around blood vessels and epithelia, providing a convenient scaffold for this …

Efficient And Universal Watermarking For Llm-Generated Code Detection, Boquan Li, Zirui Fu, Mengdi Zhang, Peixin Zhang, Jun Sun, Xingmei Wang

Research Collection School Of Computing and Information Systems

Large language models (LLMs) have significantly enhanced the usability of AI-generated code, providing effective assistance to programmers. This advancement also raises ethical and legal concerns, such as academic dishonesty and the generation of malicious code. For accountability, it is imperative to detect whether a piece of code is AI-generated. Watermarking is broadly considered a promising solution and has been successfully applied to identify LLM-generated text. However, existing efforts on code are far from ideal, suffering from limited universality and excessive time and memory consumption. In this work, we propose a plugand- play watermarking approach for AI-generated code detection, named ACW …

Continuous Query For Top-K Maximal Sum Intervals Over Streaming Data, Zhongshuai Zhang, Xiaochun Yang, Baihua Zheng, Rui Zhu, Haomin Li, Bin Wang

Research Collection School Of Computing and Information Systems

The continuous identification of top-k maximal sum intervals using a sliding window over a data stream is a critical operation for applications in IoT and beyond. A maximal sum interval is a non-overlapping, contiguous subsequence with the maximal sum in a sequence of signed values. Existing algorithms are ill-suited for streaming contexts: they either exhaustively enumerate all intervals even for small k values, or depend on indexes that require frequent and costly restructuring. We propose a novel partition-based strategy. Our core insight is a partitioning scheme that guarantees that any maximal sum interval is fully contained within a single partition, …
