Background: The Pola Test measures associated phoria at distance and near using a variety of different targets. This testing method and interpretation is referred to as the MKH-Haase method. The aim of this study is to compare the associated phoria values measured using the MKH-Haase chart results with other associated phoria tests. Methods: Horizontal and vertical associated phorias were measu...

Mobile wallets promise to allow people to easily manage their accounts and to carry less cards. However, the slow adoption of contactless point of sales (POS) terminals by merchants limits the potential of Near-Field Communication (NFC) based payment devices. In this paper, we discuss Wild Card, a secure and backward compatible way to make mobile payment through conventional magnetic stripe bas...

RbpA and CarD are essential transcription regulators in mycobacteria. Mechanistic analyses of promoter open complex (RPo) formation establish that RbpA and CarD cooperatively stimulate formation of an intermediate (RP2) leading to RPo; formation of RP2 is likely a bottleneck step at the majority of mycobacterial promoters. Once RPo forms, CarD also disfavors its isomerization back to RP2. We de...

The author describes how he came to be employed, in 1957, as a programmer at Nelson Research Laboratories (Stafford), then the hub of the English Electric Company’s software activities, at a time when the throughput of the English Electric DEUCE computer had just been potentially improved by doubling the amount of data that could be punched on each Hollerith input card, necessitating a correspo...

This article describes preliminary results from a natural experiment that tested the impact of report cards on employees. As part of the 1995 enrollment process, some members of the State of Minnesota Employee Group Insurance Program received report cards on the plans offered to them, and others did not. Both groups of employees had a chance to review a second community-wide report card coverin...

Near Field Communication (NFC) as an emerging technology is currently leveraged by large standardization efforts and tries to find a suitable ecosystem. NFC enabled mobile devices with integrated smart cards introduce compelling opportunities and new business models. Development of new standards such as secure element (SE), smart card, secure channel, as well as JavaCard enables creating new ec...

Software card emulation is a new approch to advance the interoperability of NFC with legacy contactless smartcard systems. It has been first introduced to NFC-enabled mobile phones by Research In Motion (RIM) on their BlackBerry platform. Software card emulation aims at opening and simplifying the complex and tightly controlled card emulation functionality. While this form of card emulation, th...
