High-Density, Homogenous Bacterial Spore Distributions on Test Surfaces

This method uses polycarbonate membrane to transfer spores onto a mirror surface.

Thus far, spore transfer had been successful from the polycarbonate membrane onto stainless steel, aluminum, and to some extent, glass. In order to image the endospores under an ESEM...

Detecting High Stress in Oral Interviews and Text Documents

Content of an interview or text is subjected to various levels of statistical analysis to determine if the person knows the truth and is communicating it.

When a person is interviewed, some of the answers may be inaccurate, or even deceptive, because the person may have either...

Predicting Heart Age Using Electrocardiography

Knowledge of a patient’s cardiac age, or “heart age,” could prove useful to both patients and physicians for encouraging lifestyle changes that are potentially beneficial for cardiovascular health. This may be particularly true for patients who exhibit symptoms, but who test negative for...

Prediction of Visual Acuity from Wavefront Aberrations

This automated vision test is accurate, simple, and fast.

Visual acuity (clearness of vision) usually is measured by an eye doctor using an eye chart. It measures the smallest letters that can be reliably identified by the patient at a specified distance. The traditional test...
