1. Visualization Tool: Exploring COVID-19 Data

Abstract

The ability to effectively visualize data is crucial in the contemporary world where information is often voluminous and complex. Visualizations, such as charts, graphs, and maps, provide an intuitive and easily understandable means to interpret, analyze, and communicate patterns, trends, and insights hidden within large datasets. These graphical representations can help researchers, policymakers, and the public to better comprehend and respond to a multitude of issues. In this study, we explore a visualization tool to interpret and understand various data of COVID-19 pandemic. While others have shown COVID-19 visualization methods/tools, our tool provides a mean to analyze COVID-19 data in a more comprehensive way. We have used the public data from NY Times and CDC, and various COVID-19 data (e.g., core places, patterns, foot traffic) from Safegraph. Figure 1 shows the basic view of our visualization view. In addition to providing visualizations of these data, our visualization also considered the Surprising Map. The Surprising Map is a type of choropleth map that can avoid misleading of producing visual prominence to known base rates or to artifacts of sample size and normalization in visualizing the density of events in spatial data. It is based on Bayesian surprise-it creates a space of equi-plausible models and uses Bayesian updating to re-estimate their plausibility based on individual events., Comment: Published in ISIITA 2024

19. Empirical Investigation of Sport Trademark Dilution Using Contingent Valuation Method.

Abstract

Under the federal trademark law, owners of famous sport trademarks may bring legal claims against unauthorized users of their marks under the infringement and dilution theory. Although the rationale of trademark infringement has been supported by various notions of consumer psychology and law and economics, the theory of dilution has been criticized for the lack of empirical support. This study investigated whether the junior use of major sport trademarks would have dilutive effects on the senior marks in financial terms. The study employed the contingent valuation method, a technique designed to estimate the economic values of nonpecuniary assets such as trademarks. A total of 140 subjects were exposed to dilutive information while they purchased sport brand merchandise. A series of pre- and posttests revealed that moderately famous sport trademarks suffered dilutive harm from junior use, whereas exceptionally famous marks were immune to the dilutive effects. Theoretical and practical implications were discussed. [ABSTRACT FROM AUTHOR]

40. Activation of non-basal <c + a> slip in multicomponent Mg alloys.

Abstract

Activating non-basal < c + a > slip is a key method to improve room temperature ductility and formability of Mg alloys. However, the detailed criterion for activation of the < c + a > slip in multicomponent Mg alloys, which can be utilized in commercial Mg alloys, requires further understanding. The present authors investigated the mechanism and criterion using a molecular statics simulation on dislocation behaviors in multicomponent Mg alloys. We found that if multicomponent Mg alloys have an equivalent dislocation binding intensity to associated binary Mg alloys that are optimized to minimize the critical resolved shear stress anisotropy and thus activate the < c + a > slip, then the critical resolved shear stress anisotropy between slip systems of the multicomponent Mg alloys can also be minimized, resulting in activation of the < c + a > slip. The activation is maximized in multicomponent Mg alloys when alloying a large amount of weak dislocation binding elements. It was confirmed through experiments that the multicomponent Mg alloys satisfying the above criterion show higher room-temperature tensile elongation and formability than other alloys.

41. Automated Detection of Solar Loops by the Oriented Connectivity Method

Author

Lee, Jong Kwan, Newman, Timothy S, and Gary, G. Allen

Subjects
Solar Physics
Abstract

An automated technique to segment solar coronal loops from intensity images of the Sun s corona is introduced. It exploits physical characteristics of the solar magnetic field to enable robust extraction from noisy images. The technique is a constructive curve detection approach, constrained by collections of estimates of the magnetic fields orientation. Its effectiveness is evaluated through experiments on synthetic and real coronal images.

Abstract

A new method to automatically track objects in the process of sterile pharmacy compounding is introduced. The method performs the automatic object tracking by applying a simple object detection followed by an object tracking algorithm. The advantages of the method are that it enables both single and multiple object tracking without requiring large sets of templates or training sets. The experimental results show that the method reasonably tracks the objects accurately.
