This document is a demonstration document, prepared for PolyX Ltd., demonstrating the use of the Polynomial Toolbox for Matlab when designing residual generators for fault diagnosis. A brief introduction to the residual generation problem for fault diagnosis in linear systems is given and a solution based on polynomial methods are outlined. Also, a design example, complete with MATLAB code illu...

We study the possible racial bias of the police involved in NYPD’s “stop and frisk program.” A model is introduced to explore the identification of two distinct sources of bias: bias at the level of the police officer making the stop decisions, and bias at the level of the police chief allocating manpower across precincts. Previous research offered positive identification results regarding offi...

Although mesial temporal lobe epilepsy (mTLE) is characterized by the pathological changes in mesial temporal lobe, function alteration was also found in extratemporal regions. Our aim is to investigate the information flow between the epileptogenic zone (EZ) and other brain regions. Resting-state functional magnetic resonance imaging (RS-fMRI) data were recorded from 23 patients with left mTLE...

This article explores patterns of police ”stop and frisk” activity across New York City neighborhoods. While “Broken Windows” theory may account for higher stop and frisk activity for “quality of life” crimes, the authors suggest neighborhood characteristics like racial composition, poverty levels, and extent of social disorganization are strong predictors of raceand crime-specific stops. The a...

Social justice issues remain some of the most pressing problems in the United States. One aspect of social justice involves the differential treatment of demographic groups in the criminal justice system. While data consistently show that Blacks and Hispanics are often treated differently than Whites, one understudied aspect of these disparities is how police officers' assessments of suspects' ...

BACKGROUND The urea blood test (Ez-HBT) has been shown to compare favourably with the urea breath test in the diagnosis of active Helicobacter pylori infection. AIM To examine the performance characteristics of the Ez-HBT Helicobacter blood test in establishing success or failure of therapy in H. pylori-infected adults using the 13C urea breath test as the reference method. METHODS 13C urea...
