Uncovering near-wall blood flow from sparse data with physics-informed neural networks
Amirhossein Arzani, Jian-Xun Wang, Roshan M. D'Souza
Near-wall blood flow and wall shear stress (WSS) regulate major forms of cardiovascular disease, yet they are challenging to quantify with high fidelity. Patient-specific computati…
Integrating multi-fidelity blood flow data with reduced-order data assimilation
Milad Habibi, Roshan M. D'Souza, Scott T. M. Dawson +1
High-fidelity patient-specific modeling of cardiovascular flows and hemodynamics is challenging. Direct blood flow measurement inside the body with in-vivo measurement modalities s…
An Application of Manifold Learning in Global Shape Descriptors
Fereshteh S. Bashiri, Reihaneh Rostami, Peggy Peissig +2
With the rapid expansion of applied 3D computational vision, shape descriptors have become increasingly important for a wide variety of applications and objects from molecules to p…
A Brief Comparison Between Available Bio-printing Methods
Ali Bakhshinejad, Roshan M D'Souza
The scarcity of organs for transplant has led to large waiting lists of very sick patients. In drug development, the time required for human trials greatly increases the time to ma…
Application of Independent Component Analysis Techniques in Speckle Noise Reduction of Retinal OCT Images
Ahmadreza Baghaie, Roshan M. D'souza, Zeyun Yu
Optical Coherence Tomography (OCT) is an emerging technique in the field of biomedical imaging, with applications in ophthalmology, dermatology, coronary imaging etc. OCT images us…
State-of-the-Art in Retinal Optical Coherence Tomography Image Analysis
Ahmadreza Baghaie, Roshan M. D'souza, Zeyun Yu
Optical Coherence Tomography (OCT) is one of the most emerging imaging modalities that has been used widely in the field of biomedical imaging. From its emergence in 1990's, plenty…
Fast Mesh-Based Medical Image Registration
Ahmadreza Baghaie, Zeyun Yu, Roshan M. D'souza
In this paper a fast triangular mesh based registration method is proposed. Having Template and Reference images as inputs, the template image is triangulated using a content adapt…
Sparse And Low Rank Decomposition Based Batch Image Alignment for Speckle Reduction of retinal OCT Images
Ahmadreza Baghaie, Roshan M. D'souza, Zeyun Yu
Optical Coherence Tomography (OCT) is an emerging technique in the field of biomedical imaging, with applications in ophthalmology, dermatology, coronary imaging etc. Due to the un…
High-resolution structure of viruses from random diffraction snapshots
A. Hosseinizadeh, P. Schwander, A. Dashti +3
The advent of the X-ray Free Electron Laser (XFEL) has made it possible to record diffraction snapshots of biological entities injected into the X-ray beam before the onset of radi…
Fast -NNG construction with GPU-based quick multi-select
Ivan Komarov, Ali Dashti, Roshan D'Souza
In this paper we describe a new brute force algorithm for building the -Nearest Neighbor Graph (-NNG). The -NNG algorithm has many applications in areas such as machine le…
