Central presbycusis

The Laryngoscope, 1985
AbstractThe phenomenon of central presbycusis has been investigated employing a central auditory battery in elderly individuals with essentially normul hearing. The studies indicate a progressive loss in central auditory competence measured by simultaneous binaural challenges and frequency and temporal distortion tests.

Central Hypothyroidism

2015
Central Hypothyrodism (CeH) is the hypothyroid condition due to an insufficient stimulation by thyrotropin (TSH) of an otherwise normal thyroid gland. CeH is about 1,000-fold more rare than primary hypothyroidism and raises several challenges for the clinicians, mainly because they cannot rely on the systematic use of the “reflex TSH strategy” for ...

Network Centrality: An Introduction

A Mathematical Modeling Approach from Nonlinear Dynamics to Complex Systems, 2018
Centrality is a key property of complex networks that influences the behavior of dynamical processes, like synchronization and epidemic spreading, and can bring important information about the organization of complex systems, like our brain and society ...

Central tinnitus

Auris Nasus Larynx, 2003
Tinnitus is likely initiated by a discontinuity in the spontaneous or low-level-stimulus induced neural activity across auditory nerve fibers with different characteristic frequency (CF). This discontinuity may be caused by functional loss of outer hair cells in those regions where inner hair cells are preserved.

A multi-centrality index for graph-based keyword extraction

Information Processing & Management, 2019
Keyword extraction aims to capture the main topics of a document and is an important step in natural language processing (NLP) applications. The use of different graph centrality measures has been proposed to extract automatic keywords. However, there is

Improved centrality indicators to characterize the nodal spreading capability in complex networks

Applied Mathematics and Computation, 2018
In this paper, we deeply investigate the identification of influential spreaders in complex networks based on various centrality indices. At first, we introduce several frequently used centrality indices to characterize the node influence. Then, based on

Central clocking

Trends in Neurosciences, 1997
The main questions in circadian neurobiology are: how many oscillators are involved; how are their daily oscillations generated and synchronized to the external world; and how do they signal time of day to the organism. The suprachiasmatic nuclei of the hypothalamus (SCN) are well established as the principal circadian oscillator of mammals.

Central hypothyroidism

Pituitary, 2008
Central hypothyroidism (CH) is a rare cause of hypothyroidism due to an insufficient stimulation of an otherwise normal thyroid gland and it is caused by either pituitary (secondary hypothyroidism) or hypothalamic (tertiary hypothyroidism) defects.

The location of retail stores and street centrality in Guangzhou, China

Applied Geography, 2018
Transportation networks have a profound influence on the location of retail stores, but there has been little research on the relationship between the location of retail stores and street centrality in traditional commercial metropolises.
