Effects Of Vertical Reinforcement On The Shear Performance Of Uhpc Deep Beams With Synthetic And Steel Fibres, Hossein Mirzaaghabeik, Sanjay Kumar Shukla, Nuha S. Mashaan

Research outputs 2022 to 2026

This study examines the shear behaviour of ultra-high-performance concrete deep beams (UHPC-DBs) reinforced with three fibre types: 2 % hooked-end (HE) steel fibres, 0.76 % 5D steel fibres, and 0.11 % Forta-Ferro (FF) synthetic fibres. It evaluates the effects of fibre type, fibre content, vertical web reinforcement (ρsv), and shear span-to-depth ratio (λ) on shear capacity. Load-deflection curves, crack patterns, and ρsv strain were analysed, and the optimal ρsv was determined using the particle swarm optimization (PSO) algorithm to maximise shear capacity while minimising costs. Findings reveal that, compared to specimens without ρsv, those with ρsv = 0.38 % exhibit …

Research outputs 2022 to 2026

Microplastic (MP) pollution has emerged as a threat to drinking water quality, where fibres are the dominant type of MPs found in drinking/wastewater treatment plant influents. The potential of MP removal through conventional treatment has not been vastly studied. Accordingly, this study investigates the removal of MP fibres using two-hybrid methods: coagulation-flocculation followed by sedimentation (CFS); and coagulation-flocculation combined with flotation using microbubbles (CFm) in the presence of two different water matrices, deionised water (DI) containing surfactants and DI water in the presence of humic acid (HA). A typically used Aluminium-based coagulant (AlCl3.6H2O) and a green-based coagulant, Chitosan, were employed …

A Predictive Model For The Shear Capacity Of Ultra-High-Performance Concrete Deep Beams Reinforced With Fibers Using A Hybrid Ann-Anfis Algorithm, Hossein Mirzaaghabeik, Nuha S. Mashaan, Sanjay Kumar Shukla

Research outputs 2022 to 2026

Ultra-high-performance concrete (UHPC) has attracted considerable attention from both the construction industry and researchers due to its outstanding durability and exceptional mechanical properties, particularly its high compressive strength. Several factors influence the shear capacity of UHPC deep beams, including compressive strength, the shear span-to-depth ratio (λ), fiber content (FC), vertical web reinforcement (ρsv), horizontal web reinforcement (ρsh), and longitudinal web reinforcement (ρs). Considering these factors, this research proposes a novel hybrid algorithm that combines an adaptive neuro-fuzzy inference system (ANFIS) with an artificial neural network (ANN) to predict the shear capacity of UHPC deep beams. To achieve this, ANN and …

Paradoxical Leadership As Facilitator In The Idea Journey: The Role Of Regulatory Focus, Irene E. De Pater, Shenghui Wang, Ming Yi, Eric F. Rietzschel

Research outputs 2022 to 2026

Drawing upon theory and research on innovation, conservation of resources, and paradoxical leadership, we examine relationships between three stages of the innovative process (i.e., idea generation, idea dissemination, and idea implementation) and the role of paradoxical leadership as a facilitator of the transitions between these stages. In addition, we examine the motivational mechanisms (promotion and prevention focus) that can explain the relevance of paradoxical leadership in the innovative process. Results of a four-wave study show that paradoxical leadership, through employee promotion focus, strengthens the relationship between idea generation and idea dissemination, whereas paradoxical leadership, through employee prevention focus, strengthens the …

Cysteine Depletion Triggers Adipose Tissue Thermogenesis And Weight Loss, Aileen H Lee, Irina Shchukina, Prabhakar Sairam Andhey, Maxim N Artyomov, Et Al. Jun 2025

Cysteine Depletion Triggers Adipose Tissue Thermogenesis And Weight Loss, Aileen H Lee, Irina Shchukina, Prabhakar Sairam Andhey, Maxim N Artyomov, Et Al.

2020-Current year OA Pubs

Caloric restriction and methionine restriction-driven enhanced lifespan and healthspan induces 'browning' of white adipose tissue, a metabolic response that increases heat production to defend core body temperature. However, how specific dietary amino acids control adipose thermogenesis is unknown. Here, we identified that weight loss induced by caloric restriction in humans reduces thiol-containing sulfur amino acid cysteine in white adipose tissue. Systemic cysteine depletion in mice causes lethal weight loss with increased fat utilization and browning of adipocytes that is rescued upon restoration of cysteine in diet. Mechanistically, cysteine-restriction-induced adipose browning and weight loss requires sympathetic nervous system-derived noradrenaline signalling via …

Ecological Responsibility In The City: The Surfaces And Volumes Of Urban Mosquito Management, Orlando Woods, Sayd Randle Jun 2025

Ecological Responsibility In The City: The Surfaces And Volumes Of Urban Mosquito Management, Orlando Woods, Sayd Randle

Research Collection College of Integrative Studies

This paper explores how ecological responsibility becomes distributed across the surfaces and volumes of the city. Our focus is urban mosquito management – specifically, the management of the Aedes aegypti mosquito, the vector by which dengue and several other diseases are transmitted to humans – and the governance strategies deployed in Singapore to manage breeding sites and mosquito outbreaks. Whilst the governance of nature in Singapore is usually undertaken by the state, the effective management of mosquitoes requires responsibility for ecological management to become distributed throughout the city. Residents are expected to assume responsibility for surficial cleanliness and the removal …

Infrastructural Splintering Along The Bri: Catholic Political Ecologies And The Fractious Futures Of Sri Lanka’S Littoral Spaces, Orlando Woods Jun 2025

Infrastructural Splintering Along The Bri: Catholic Political Ecologies And The Fractious Futures Of Sri Lanka’S Littoral Spaces, Orlando Woods

Research Collection College of Integrative Studies

This article considers the ways in which the material infrastructures of China’s Belt and Road Initiative (BRI) intersect with other infrastructural formations, and how the resulting overlaps can trigger processes of what I call “infrastructural splintering”. These processes cause infrastructure to be experienced in differentiating ways, creating divisive politics where there might once have been unity. Embracing these politics as an analytical starting point undermines the techno-material stability of the BRI, and reveals its more-than-material affects. I illustrate these ideas by developing a case study of the effects of the China-backed Colombo Port City project on Catholic fishing communities that …

Techno-Geopolitics And Semi-Conductor Chokepoints: Beyond The Us-China Wto Dispute, Han-Wei Liu, Ching-Fu Lin Jun 2025

Techno-Geopolitics And Semi-Conductor Chokepoints: Beyond The Us-China Wto Dispute, Han-Wei Liu, Ching-Fu Lin

Research Collection Yong Pung How School Of Law

Much ink has been spilled on the US-China tech and trade war, particularly the role of US export controls in containing China and preserving America’s tech dominance. Less attention, however, has been paid to other critical nodes in the global semiconductor supply chain – Taiwan, South Korea, Japan, and the Netherlands – which we coin as ‘chokepoint economies’. Taiwan alone produces over 90% of the world’s most advanced chips, vital to the digital age and the future of AI in the Indo-Pacific and beyond. Using Taiwan as a case study, this paper shows how chokepoint economies navigate competing pressures amid …

Unsupervised Recognition Of Unknown Objects For Open-World Object Detection, Ruohuan Fang, Guansong Pang, Wenjun Miao, Xiao Bai, Jin Zheng, Xin Ning

Research Collection School Of Computing and Information Systems

Open-world object detection (OWOD) extends object detection problem to a realistic and dynamic scenario, where a detection model is required to be capable of detecting both known and unknown objects and incrementally learning newly introduced knowledge. Current OWOD models detect the unknowns that exhibit similar features to the known objects, but they suffer from a severe label bias problem, i.e., they tend to detect all regions (including unknown object regions) that are dissimilar to the known objects as part of the background. To eliminate the label bias, this article proposes a novel module, namely reconstruction error-based Weibull (REW) model, that …

Biomolecular Condensates In Immune Cell Fate, Srikanth Kodali, Caroline M Sands, Lei Guo, Yun Huang, Bruno Di Stefano Jun 2025

Biomolecular Condensates In Immune Cell Fate, Srikanth Kodali, Caroline M Sands, Lei Guo, Yun Huang, Bruno Di Stefano

Faculty, Staff and Students Publications

Fate decisions during immune cell development require temporally precise changes in gene expression. Evidence suggests that the dynamic modulation of these changes is associated with the formation of diverse, membrane-less nucleoprotein assemblies that are termed biomolecular condensates. These condensates are thought to orchestrate fate-determining transcriptional and post-transcriptional processes by locally and transiently concentrating DNA or RNA molecules alongside their regulatory proteins. Findings have established a link between condensate formation and the gene regulatory networks that ensure the proper development of immune cells. Conversely, condensate dysregulation has been linked to impaired immune cell fates, including ageing and malignant transformation. This Review …

Graphage: Unleashing The Power Of Graph Neural Network To Decode Epigenetic Aging, Saleh Sakib Ahmed, Nahian Shabab, Abul Hassan Samee, M Sohel Rahman

Faculty, Staff and Students Publications

DNA methylation is a crucial epigenetic marker used in various clocks to predict epigenetic age. However, many existing clocks fail to account for crucial information about CpG sites and their interrelationships, such as co-methylation patterns. We present a novel approach to represent methylation data as a graph, using methylation values and relevant information about CpG sites as nodes, and relationships like co-methylation, same gene, and same chromosome as edges. We then use a graph neural network (GNN) to predict age. Thus our model, GraphAge leverages both the structural and positional information for prediction as well as better interpretation. Although, we …

A Sumo-Interacting Motif In The Guanine Nucleotide Exchange Factor Epac1 Is Required For Subcellular Targeting And Function, Wenli Yang, Fang Mei, Wei Lin, Jason E Lee, Si Nie, Christopher J Bley, André Hoelz, Xiaodong Cheng

The Brown Foundation: Institute of Molecular Medicine

Exchange protein directly activated by cAMP (EPAC1), a multifunctional intracellular cAMP receptor, dynamically localizes to various cellular loci, engaging with diverse molecular partners to maintain cellular homeostasis. The study investigates the role of the SUMO-interacting motif (SIM) in the subcellular targeting and cellular functions of EPAC1. It reveals that the SIM is a critical structural element for EPAC1's association with RanBP2/nucleoporin 358, a nucleoporin of the cytoplasmic filament component of the nuclear pore complex. Mutational disruption of EPAC1 SIM interferes with EPAC1's ability to activate its canonical effectors, small GTPases, Rap1 and Rap2, and noncanonical functions, such as the formation …

Direct pacing of the mid myocardium where re-entry originates can be used to prevent ventricular arrhythmias and circumvent the need for painful defibrillation or cardiac ablation. However, there are no pacing electrodes small enough to navigate the coronary veins that cross these culprit scar regions. To address this need, we have developed an injectable ionically conductive hydrogel electrode that can fill the epicardial coronary veins and transform them into flexible electrodes. A new hydrogel chemistry based on a polyether urethane diacrylamide macromer was developed that matches myocardial stiffness and is resistant to hydrolysis. Conductivity was imparted using ionic precursor solutions …

Hypophosphatasia (HPP) is an inherited disorder that affects bone and tooth mineralization, among other body systems. HPP is caused by pathogenic variants in the alkaline phosphatase-liver (ALPL) gene, which encodes tissue nonspecific alkaline phosphatase. One major challenge in diagnosing HPP is interpreting variant of uncertain significance (VUS), which can create uncertainty for patients and healthcare professionals, leading to delays in diagnosis and treatment or incorrect diagnoses. Since February 2021, the ALPLgene variant consortium has reclassified 100 VUS using adjusted American College of Medical Genetics/Association for Molecular Pathology criteria. Of these, 11 were reclassified as pathogenic, 62 as …

On average, women faculty take on more childcare responsibilities, posing barriers to career success. Work-family policies represent one solution for advancing gender equity in academia as they support parents after childbirth with benefits for children, employees, and organizations. We contribute to understanding how the availability and use of dependent care policies (paid parental leave and childcare benefits) relate to long-term research productivity trends. Based on the work-home resources model, we theorize that policy availability provides contextual resources and policy use provides personal resources, leading to improvements in an individual's research productivity after they have a child. We also examine potential …

Electrical and Computer Engineering Faculty Publications and Presentations

This study presents a probabilistic one-step two-dimensional (2D) inversion method of spherical-wave reflection coefficient data to estimate the range-dependent structure and geoacoustic parameters along a track. The approach of inverting such datasets independently as one-dimensional (1D) layered models and merging them to a 2D section is feasible but computationally expensive. This study demonstrates a more parsimonious 2D parametrization for active source data recorded on a towed hydrophone array. The comparison of data variance reduction for 1D- and 2D-based results clearly favors the 2D parametrization described here.

Distributed Energy Resources: A Systematic Literature Review, Midrar Adham, Sean Keene, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

The traditional power grid, characterized by its centralized nature and one-way power flow, has long been the backbone of electricity supply and distribution. Grid operators have historically found various ways to accurately predict demand, anticipate faults, and prepare appropri- ate responses. However, with the rapid integration of Distributed Energy Resources such as Photovoltaic, storage systems, grid-interactive generation, and flexible-load assets, energy consumption and production patterns have become less predictable, transforming the grid into a two-way power flow system. Managing the potential of these Distributed Energy Resources requires advanced management systems that provide monitoring, coordination, and aggregation capabilities to …
