quantizers were designed with the primary concerns of bit-rate and complexity, less attention was paid to error propagation. In this paper, we consider the erasure performance of LSF differential scalar quantizer (DSQ) and compare it with the interframe coding method embedded in the standard G723.1 of the ITU. Our results show that with only 5% extra bit-rate, DSQ algorithm is much more robust ...

BACKGROUND In clinical practice, dietary sodium assessment requires reliable and rapid screening tools. We wished to evaluate the usefulness of food frequency questionnaires (FFQ) in estimating dietary sodium intakes in haemodialysis patients. METHODS We used the Derby Salt Questionnaire (DSQ), and Scored Sodium Questionnaire (SSQ) to estimate sodium intake. Body composition was determined by...

On the basis of existing dust collector structure, this study designed a fan-shaped new structure microporous membrane filter plate (NSMMFP). The pressure distribution law NSMMFP can be obtained by measuring wall surface peak under different injection pressures. powder attachment experiment was carried out to explore influence moisture content on stripping rate (DSR), and high-speed camera used...

Purpose: The aims of this study are to examine the effect digital service quality on customer engagement with telemedicine systems and investigate how such effects change depending a variety socioeconomic characteristics. Design/methodology/approach: survey research online questionnaire was conducted 405 experienced samples. proposed hypotheses were tested using Structural Equation Modeling (SE...

Expert musicians portray awe-inspiring precision, timing, and phrasing may be thought to partake in a “hive-mind.” Such shared musical absorption is characterized by heightened empathic relation, mutual trust, sense that the music “takes over,” thus uniting performers’ intentions. Previous studies have found correlations between concern or experience cardiac synchrony (CS). We aimed investigate...

BACKGROUND To explore and better understand how patients evaluate satisfaction in dental care and elicit information from them to develop a dental satisfaction instrument. METHODS Patients currently receiving dental treatment in a teaching hospital were invited to be part of a qualitative research project which involved focus group discussion. Focus groups were conducted in Cantonese and disc...

IMPORTANCE Chronic fatigue syndrome (CFS) is characterised by a constellation of symptoms diagnosed with a number of different polythetic criteria. Heterogeneity across these diagnostic criteria is likely to be confounding research into the as-yet-unknown pathophysiology underlying this stigmatised and debilitating condition and may diagnose a disease spectrum with significant implications for ...

Aims: To assess the level of satisfaction with dental care among dental students and to know whether students in different stages of the dental course had any difference in their level of satisfaction with dental care. Methods: 372 students from first to final year and interns completed the nineteen item Dental Satisfaction Questionnaire (DSQ). Results: The mean DSQ total was 49.64±10.3. The co...
