Pseudonystagmus—clinical features and quantitative characteristics

Nature Reviews Neurology, 2010
A 60 year-old woman with multiple sclerosis (MS) and chronic hearing loss presented with head tremor and vestibular hypofunction, the combination of which can produce oscillopsia--a visual sensation that steady objects in the visual field are oscillating.

Quantitative electrophysiological characteristics and subtyping of schizophrenia

Biological Psychiatry, 1994
Quantitative descriptors of resting electroencephalogram (EEG) (QEEG) and event-related potentials (QERP) to visual and auditory stimuli were obtained from normal subjects and 94 chronic schizophrenic patients on medication, 25 chronic schizophrenics off medication, and 15 schizophrenics with no history of medication.

Effect of Selection on a Quantitative Characteristic

Biometrical Journal, 1992
AbstractIn this paper we study the effect of selection procedures on certain parameters of the distribution function (d.f.) (such as mean, percentile etc.) of a quantitative characteristic X, in successive generations when the d.f. is governed by a single locus.

Quantitative Characteristics of Singular Measures

1971
The main part of this note is a continuation of the work [1] of M. Sh. Birman and M. Z. Solomyak. In that paper various results in the theory of approximation are obtained. The approach adopted in [1] is based on a systematic use of the theorem on set functions which is proved there.

The use of AFM in quantitative analysis of pore characteristics in coal and coal-bearing shale

Marine and Petroleum Geology, 2019
Quantitative characterization of nanopore structure is of great importance for both accurate assessment of gas reservoir capacity and gas migration behaviors. In this work, atomic force microscopy (AFM) experiments were performed on coal and coal-bearing

Quantitative misorientation characteristics of interphase boundaries in composites

Journal of Microscopy, 2006
SummarySpecific crystallographic correlations between neighbouring grains in composites were established by the use of selected area electron diffraction in the transmission electron microscope. However, it was the development of orientation mapping techniques that made it possible to obtain a quantitative description of the distribution of boundaries ...

Update on Techniques for the Quantitation of Facial Skin Characteristics

Facial Plastic Surgery Clinics of North America, 2013
The purpose of this article is to review the strategies and methods for quantifying treatment outcomes, perhaps defined by the consumer/patient as a "decrease in perceived age." The demand for the rejuvenation of facial skin is expected to increase as the population ages and seeks optimal outcomes from the array of available treatment modalities.
