3d Reconstruction Of Spatial Transcriptomics With Spatial Pattern Enhanced Graph Convolutional Neural Network, Chen Tang, Yuansheng Zhou, Xue Xiao, Lei Dong, Lei Yu, Guanghua Xiao

Faculty, Staff and Student Publications

Spatially resolved transcriptomics (SRT) is a promising new technology that enables simultaneous analysis of gene expression and spatial information for biomedical research. However, the existing statistical and deep learning algorithms used for analyzing SRT data rely solely on two-dimensional (2D) spatial coordinates, which limits their ability to accurately identify spatial domains, spatially variable genes (SVGs), cell-to-cell communications, and developmental trajectories in a three-dimensional (3D) spatial manner. To address these limitations, we introduced Spa3D, which utilized the anti-leakage Fourier transform and graph convolutional neural network model to reconstruct 3D-based spatial structures from multiple 2D SRT slices. We demonstrate that Spa3D is …

Peninsula Medical School

Objectives Perioperative randomised controlled trials (RCTs) in liver transplantation are relatively infrequent. RCTs performed in this complex patient population need to be robustly conducted to maximise patient benefit and graft utility given the scarcity of donor organs. Recruitment challenges can compromise RCTs and studies in this population face unique challenges due to recipient illness severity, their comorbidities, demographics and the geographical constraints of specialist transplant centres. Emergency presentation and after-hours admission may further limit patients’ capacity or readiness to consider trial participation. This Study Within a Trial (SWAT) specifically explored motivators and barriers to recruitment in patients awaiting liver transplantation.Design …

Integrated Road Usage Fee Management Within Digital Navigation Systems, Paula Marques

Defensive Publications Series

Digital navigation systems may identify routes with fee-based road segments, such as tolls or vignettes, but may not provide an integrated method for payment. This can result in a fragmented and manual process for drivers with varied and unfamiliar payment systems. A system is described for integrating road usage fee management within a digital navigation service. The system can utilize a route analysis engine to identify fees, a client-side geofencing module on a computing device (e.g., a smartphone, smart watch, wearable device, in-vehicle infotainment system, augmented reality glasses, etc.) To detect a vehicle's entry into a fee-based zone, and a …

Quantitative Analysis Of Psychological Safety, Resilience, And Intraminority Solidarity As Predictors Of Racial Trauma Distress Among Bipoc College Students, Miguel A. Castano, Richard Chang, Gloria Wong-Padoongpatt

Spectra Undergraduate Research Journal

Racial trauma distress is when post-traumatic stress disorder symptoms occur due to repeated and cumulative experiences of racism and can negatively impact Black, Indigenous, and people of color (BIPOC). Consensus in research findings strongly suggests that BIPOC students are more likely to experience racism on university campuses than non-BIPOC students. To mitigate some of these negative outcomes, existing research has shown that psychological safety, resilience, and intraminority solidarity are protective factors for BIPOC students experiencing race-related distress. However, little is known about the frequency of racial trauma distress among BIPOC college students and how these variables may protect against racial …

Constitutional Time: The Temporal Dimension Of Precedent In Consitutional Jurisprudence, Laura A. Cisneros
