Disease vector

AGENT THAT CARRIES AND TRANSMITS AN INFECTIOUS PATHOGEN INTO ANOTHER LIVING ORGANISM

Vector species; Insect-borne disease; Vector (epidemiology); Vector borne transmission; Vector (disease); Vector (parasitology); Insect vectors; Disease vectors; Insect vector; Contagion vector; Vector-borne disease; Disease-vector; Draft:Vector-Borne Disease; Vector competence; Vector-borne

In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen to another living organism; agents regarded as vectors are organisms, such as parasites or microbes. The first major discovery of a disease vector came from Ronald Ross in 1897, who discovered the malaria pathogen when he dissected a mosquito.

Clinical coder

HEALTH CARE PROFESSIONAL WHOSE MAIN DUTIES ARE TO ANALYSE CLINICAL STATEMENTS AND ASSIGN STANDARD CODES USING A CLASSIFICATION SYSTEM

Medical coder; Medical coding; Clinical coding; Medical coding specialist

A clinical coder—also known as clinical coding officer, diagnostic coder, medical coder, or nosologist—is a health information professional whose main duties are to analyse clinical statements and assign standard codes using a classification system. The Health data produced are an integral part of health information management, and are used by local and national governments, private healthcare organizations and international agencies for various purposes, including medical and health services research, epidemiological studies, health resource allocation, case mix management, public health programming, medical billing, and public education.

Speech coding

Speech coding is an application of data compression of digital audio signals containing speech. Speech coding uses speech-specific parameter estimation using audio signal processing techniques to model the speech signal, combined with generic data compression algorithms to represent the resulting modeled parameters in a compact bitstream.

Some applications of speech coding are mobile telephony and voice over IP (VoIP). The most widely used speech coding technique in mobile telephony is linear predictive coding (LPC), while the most widely used in VoIP applications are the LPC and modified discrete cosine transform (MDCT) techniques.

The techniques employed in speech coding are similar to those used in audio data compression and audio coding where knowledge in psychoacoustics is used to transmit only data that is relevant to the human auditory system. For example, in voiceband speech coding, only information in the frequency band 400 to 3500 Hz is transmitted but the reconstructed signal is still adequate for intelligibility.

Speech coding differs from other forms of audio coding in that speech is a simpler signal than most other audio signals, and a lot more statistical information is available about the properties of speech. As a result, some auditory information that is relevant in audio coding can be unnecessary in the speech coding context. In speech coding, the most important criterion is preservation of intelligibility and pleasantness of speech, with a constrained amount of transmitted data. In addition, most speech applications require low coding delay, as long coding delays interfere with speech interaction.
