Anomaly Detection: Under the [data] hood in Smart Cars
(IEEE, 2019-08-01)This research focuses on discovering baseline models for driving behavior and vehicle functioning from data in smart cars. This facilitates detection of anomalous behaviors that deviate from such baselines. Human behavioral ... -
Why do females sing?—pair communication and other song functions in eastern bluebirds
(Oxford University Press, 2019-08-03)Female bird song has been underappreciated and understudied, especially in temperate species. Birdsong was originally thought to be a trait used primarily by male songbirds for mate attraction and male/male contest. However, ... -
An overview of online trust: Concepts, elements, and implications
(Elsevier Ltd., 2004-02-18)Lack of trust has been repeatedly identified as one of the most formidable barriers to people for engaging in e-commerce, involving transactions in which financial and personal information is submitted to merchants via the ... -
Generating photon-added states without adding a photon
(The American Physical Society, 2019-10-02)We show that a continuous range of nonclassical states of light can be generated using conditional measurements on the idler mode of an optical parametric amplifier. The output state is prepared by introducing a coherent ... -
Learning from Observations Using a Single Video Demonstration and Human Feedback
(2019-09-29)In this paper, we present a method for learning from video demonstrations by using human feedback to construct a mapping between the standard representation of the agent and the visual representation of the demonstration. ... -
Mitigating Demographic Biases in Social Media-Based Recommender Systems
(Association for Computing Machinery, 2019-08-04)As a growing proportion of our daily human interactions are digitized and subjected to algorithmic decision-making on social media platforms, it has become increasingly important to ensure that these algorithms behave in ... -
The Accretion History of AGN: A Newly Defined Population of Cold Quasars
(2019-08-15)Quasars are the most luminous of active galactic nuclei (AGN), and are perhaps responsible for quenching star formation in their hosts. The Stripe 82X catalog covers 31.3 deg² of the Stripe 82 field, of which the 15.6 deg² ... -
An implicit P-multigrid flux reconstruction method for simulation of locally preconditioned unsteady Navier–Stokes equations at low Mach numbers
(2019-08)We develop a P-multigrid solver to simulate locally preconditioned unsteady compressible Navier–Stokes equations at low Mach numbers with implicit high-order methods. Specifically, the high-order flux reconstruction/correction ... -
Social Media-based User Embedding: A Literature Review
(2019-06)Automated representation learning is behind many recent success stories in machine learning. It is often used to transfer knowledge learned from a large dataset (e.g., raw text) to tasks for which only a small number ... -
Trends in PM2.5 transition metals in urban areas across the United States
(IOP Publishing, 2019-10-04)Using data from the Environmental Protection Agency's Chemical Speciation Network, we have characterized trends in PM2.5 transition metals in urban areas across the United States for the period 2001–2016. The metals included ... -
Long-Wavelength Reflecting Filters Found in the Larval Retinas of One Mantis Shrimp Family (Nannosquillidae)
(Elsevier B.V., 2019-09-23)Both vertebrates and invertebrates commonly exploit photonic structures adjacent to their photoreceptors for visual benefits. For example, use of a reflecting structure (tapetum) behind the retina increases photon capture, ... -
In silico dermoscopy with detailed subsurface scattering
(The Eurographics Association, 2019)We describe an approach to modeling dermoscopy, the imaging modality for the examination of skin lesions, using accurate subsurface scattering in human skin. We make use of an open-source, path-tracing program with advanced ... -
THE USE OF SPIRITUALITY IN TRAINING AND ADULT EDUCATION
(IJONTE, 2011-06)Over the past decade or more, a surge of the idea of spirituality has overcome the population. This surge is apparent in our everyday lives as we watch TV, read books, surf the Internet and even in our work as companies ... -
Identifying Biases in Global Tree Cover Products: A Case Study in Costa Rica
(MDPI, 2019-09-30)Global tree cover products are widely used in analyses of deforestation, fragmentation, and connectivity, but are rarely critically assessed. Inaccuracies in these products could have consequences for future decision making, ... -
Programmable biomolecular switches for rewiring flux in Escherichia coli
(Nature, 2019-08-21)Synthetic biology aims to develop programmable tools to perform complex functions such as redistributing metabolic flux in industrial microorganisms. However, development of protein-level circuits is limited by availability ... -
Chatbot Application on Cryptocurrency
(IEEE, 2019-07-11)Many chatbots have been developed that provide a multitude of services through a wide range of methods. A chatbot is a brand-new conversational agent in the highspeed changing technology world. With the advance of Artificial ... -
Developing Machine Learning Based Predictive Models for Smart Policing
(IEEE, 2019-08-01)Crimes are problematic where normal social issues are confronted and influence personal satisfaction, financial development, and quality-of-life of a region. There has been a surge in the crime rate over the past couple ... -
Modeling phase noise in high-power photodetectors
(IEEE, 2019-08-22)We describe the simulation model that we use to calculate the impulse response and phase noise in a modified unitraveling carrier (MUTC) photodetector using the drift-diffusion equations while avoiding computationally ... -
Data Compression for Optimization of a Molecular Dynamics System: Preserving Basins of Attraction
(Springer, Cham, 2019-06-08)Understanding the evolution of atomistic systems is essential in various fields such as materials science, biology, and chemistry. The gold standard for these calculations is molecular dynamics, which simulates the dynamical ... -
Transmission characteristics of optical nanofibers in metastable xenon
(2019-06-17)We study the transmission characteristics of sub-wavelength diameter silica optical nanofibers (ONF’s) surrounded with a xenon plasma produced by a low-pressure inductive RF discharge. In contrast to related experiments ...
