Can Twitter data be used to validate travel demand models ?

In this paper we use Twitter data and a recently developed algorithm at the University of California Santa Barbara to extract Origin-Destination pairs in the Greater Los Angeles metropolitan area known as the Southern California Association of Governments (SCAG) region. This algorithm contains two steps: individual-based trajectory detection and place-based trip aggregation. In essence, if a pe...

Can poison control data be used for pharmaceutical poisoning surveillance?

OBJECTIVE To determine the association between the frequencies of pharmaceutical exposures reported to a poison control center (PCC) and those seen in the emergency department (ED). DESIGN A statewide population-based retrospective comparison of frequencies of ED pharmaceutical poisonings with frequencies of pharmaceutical exposures reported to a regional PCC. ED poisonings, identified by Int...

Can Large Deviation Theory be Used for Estimating Data Complexity?

Statistical analysis of attacks on block ciphers have mostly used normal approximations. A few recent works have proposed doing away with normal approximations and instead use Chernoff and Hoeffding bounds to obtain rigorous bounds on data complexities of several attacks. This opens up the question of whether even better general bounds can be obtained using the statistical theory of large devia...

Can Prostate Specific Antigen Be Used as New Biomarker for Early Diagnosis of Breast Cancer?

Introduction: As a glycoprotein, Plasma Prostate-Specific Antigen (PSA) is mainly produced by prostate epithelial cells and is used as a major diagnostic tool for prostate cancer. A group of researchers relate the elevated number of estrogen receptors in breast cancer samples to the over-production of PSA in this type of cancer. Therefore, the present study aimed to determine the participants' ...
