Acoustofluidic particle trapping, manipulation, and release using dynamic-mode cantilever sensors
(Royal Society of Chemistry, 2016-11-23)We show here that dynamic-mode cantilever sensors enable acoustofluidic fluid mixing and trapping of suspended particles as well as the rapid manipulation and release of trapped micro-particles via mode switching in liquid. ... -
Age-related strength loss affects non-stepping balance recovery
(Public Library of Science, 2019-01-18)Aging is associated with a higher risk of falls, and an impaired ability to recover balance after a postural perturbation is an important contributing factor. In turn, this impaired recovery ability likely stems from ... -
Agent-Based Simulation Framework for Epidemic Forecasting during Hajj Seasons in Saudi Arabia
(MDPI, 2021-08-12)The religious pilgrimage of Hajj is one of the largest annual gatherings in the world. Every year approximately three million pilgrims travel from all over the world to perform Hajj in Mecca in Saudi Arabia. The high ... -
An Algorithm for Fast Generation of Bivariate Poisson Random Vectors
(INFORMS, 2010)We present the "trivariate reduction extension" (TREx)-an exact algorithm for the fast generation of bivariate Poisson random vectors. Like the normal-to-anything (NORTA) procedure, TREx has two phases: a preprocessing ... -
Applying variance reduction ideas in queuing simulations
(Cambridge University Press, 2001)Variance reduction techniques are often underused in simulation studies. In this article, we indicate how certain ones can be efficiently employed when analyzing queuing models. The first technique considered is that of ... -
Approximate Positively Correlated Distributions and Approximation Algorithms for D-optimal Design
(2018-02-26)Experimental design is a classical problem in statistics and has also found new applications in machine learning. In the experimental design problem, the aim is to estimate an unknown vector x in m-dimensions from linear ... -
AR DriveSim: An Immersive Driving Simulator for Augmented Reality Head-Up Display Research
(2019-10-23)Optical see-through automotive head-up displays (HUDs) are a form of augmented reality (AR) that is quickly gaining penetration into the consumer market. Despite increasing adoption, demand, and competition among manufacturers ... -
Assessing elderly’s functional balance and mobility via analyzing data from waist-mounted tri-axial wearable accelerometers in timed up and go tests
(2021-03-25)Background Poor balance has been cited as one of the key causal factors of falls. Timely detection of balance impairment can help identify the elderly prone to falls and also trigger early interventions ... -
Automatic Recognition and Analysis of Balance Activity in Community-Dwelling Older Adults: Algorithm Validation
(JMIR Publications, 2021-12-20)Background: Clinical mobility and balance assessments identify older adults who have a high risk of falls in clinics. In the past two decades, sensors have been a popular supplement to mobility and balance assessment to ... -
An Autonomous Task Assignment Paradigm for Autonomous Robotic In-Space Assembly
(Frontiers, 2022-02-25)The development of autonomous robotic systems is a key component in the expansion of space exploration and the development of infrastructures for in-space applications. An important capability for these robotic systems is ... -
Benefits of integrated screening and vaccination for infection control
(2021-12)Importance: Screening and vaccination are essential in the fight against infectious diseases, but need to be integrated and customized based on community and disease characteristics. Objective: To develop effective ... -

C-NORTA: A Rejection Procedure for Sampling from the Tail of Bivariate NORTA Distributions
(INFORMS, 2012)We propose C-NORTA, an exact algorithm to generate random variates from the tail of a bivariate NORTA random vector. (A NORTA random vector is specified by a pair of marginals and a rank or product-moment correlation, and ... -
Calculating and Analyzing Angular Head Jerk in Augmented and Virtual Reality: Effect of AR Cue Design on Angular Jerk
(MDPI, 2021-10-28)In this work, we propose a convenient method for evaluating levels of angular jerk in augmented reality (AR) and virtual reality (VR). Jerk is a rarely analyzed metric in usability studies, although it can be measured and ... -
Can a Patient's In-Hospital Length of Stay and Mortality Be Explained by Early-Risk Assessments?
(PLOS, 2016-09-15)Objective To assess whether a patient’s in-hospital length of stay (LOS) and mortality can be explained by early objective and/or physicians’ subjective-risk assessments. Data Sources/Study Setting Analysis of a ... -
Capturing multi-stage fuzzy uncertainties in hybrid system dynamics and agent-based models for enhancing policy implementation in health systems research
(PLOS, 2018-04-25)Background In practical research, it was found that most people made health-related decisions not based on numerical data but on perceptions. Examples include the perceptions and their corresponding linguistic values of ... -
The CCP Selector: Scalable Algorithms for Sparse Ridge Regression from Chance-Constrained Programming
(2018-06-11)Sparse regression and variable selection for large-scale data have been rapidly developed in the past decades. This work focuses on sparse ridge regression, which considers the exact $L_0$ norm to pursue the sparsity. We ... -
