OBJECTIVES/HYPOTHESIS To determine if vestibular potentials could be elicited with electrical stimulation from cochlear implants. STUDY DESIGN Prospective cohort study. METHODS Vestibular responsiveness to electrical stimulation from cochlear implants was assessed via vestibular evoked myogenic potential (VEMP) testing in 53 pediatric and young adult patients. RESULTS Thirty-one participa...

Audiometric thresholds and otoacoustic emissions (OAEs) were measured in 285 U.S. Marine Corps recruits before and three weeks after exposure to impulse-noise sources from weapons' fire and simulated artillery, and in 32 non-noise-exposed controls. At pre-test, audiometric thresholds for all ears were <or=25 dB HL from 0.5 to 3 kHz and <or=30 dB HL at 4 kHz. Ears with low-level or absent OAEs a...

This article presents an analysis of the scattering measurements for an entire wheat growth cycle by ground-based scatterometers at a frequency of 5.3 GHz. Since wheat ears are related to wheat growth and yield, the radar backscatter of wheat was analyzed at two different periods, i.e., with and without wheat ears. Simultaneously, parameters such as wheat and soil characteristics as well as vol...

Corn (Zea mays L.) yields have increased in the United States since 1930s and other parts of world 1950s 1960s because improvements agricultural management genotypes. Despite these increases, production concerns still exist. In July 2016, abnormal ear development (multi-ears per node, barbell-ears, short-husks) was reported cornfields that extended from Texas Panhandle to eastern Colorado east ...

We measured the horizontal and vertical components of caloric nystagmus in 120 ears of 60 vertiginous patients who had moderate to vigorous caloric first-phase response in both ears, no spontaneous nystagmus, and no severe disorders in the central nervous system. We provoked a caloric first phase in the supine position with 5 ml of water at 20 degrees C for 15 seconds. We provoked a caloric sec...

OBJECTIVE the aim of this study is to describe the extension of unsafe middle ear disease in the sinus tympani and to review the methods of surgical access to remove the disease from this area. METHODS Of the 164 operated ears with unsafe chronic suppurative otitis media 64(39%) ears had variable disease extension into the sinus tympani and were included in the study. Sixty two ears underwent...

The Easy Approach to Requirements Syntax (EARS) offers a “small set of simple requirements structures” to capture and specify high-level stakeholder requirements. A group of seven authors was tasked with writing detailed requirements for subsystems of a network device. Following brief training and individual mentoring, the authors rewrote critical sections of their requirements using EARS templ...
