Regionally calibrated algorithms for water quality are strongly needed, especially for optically complex waters such as coastal areas in the Arabian Gulf. In this study, a regional qualitative algorithm was proposed to retrieve seawater transparency, with Secchi disk depth (SDD) as a surrogate, in the Arabian Gulf. A two-step process was carried out, first estimating the diffuse attenuation coe...

Same-day discharge (SDD) after catheter ablation of atrial fibrillation (AF) has become increasingly common, improving healthcare resource utilization, reducing procedure-related costs, and possibly increasing patient satisfaction. Nevertheless, most data regarding the safety SDD originate from cohorts, including patients a limited number centers. To determine efficacy our previously described ...

BACKGROUND We recently demonstrated that a 2-year subantimicrobial-dose doxycycline (SDD) regimen (double-masked, placebo-controlled clinical trial) in postmenopausal (PM) women exhibiting mild systemic bone loss (osteopenia) and local bone loss (periodontitis) reduced the progression of periodontal attachment loss (intent-to-treat analysis) and the severity of gingival inflammation and alveola...

Semidiscrete decomposition (SDD) is usually presented as a storage-eecient analogue of singular value decomposition. We show, however, that SDD actually works in a completely diierent way, and is best thought of as a bump-hunting technique; it is extremely eeective at nding outlier clusters in datasets. We suggest that SDD's success in text retrieval applications such as latent semantic indexin...

Several recent meta-analyses have shown that the use of SDD can reduce the occurrence of nosocomial pneumonia among ventilated patients in the intensive care unit (ICU) setting. However, the use of SDD has also been demonstrated to increase subsequent patient colonization and infection with antibiotic-resistant bacteria, particularly Gram-positive cocci. Therefore, the routine use of SDD cannot...

OBJECTIVES This study sought to evaluate outcomes of same-day discharge (SDD) following percutaneous coronary intervention (PCI) versus overnight hospitalization (ON). BACKGROUND Although there are data on the safety and feasibility of SDD after PCI, ON continues to be prevalent. METHODS The Cochrane search strategy was used to search the PubMed database, EMBASE, and the Cochrane Library fo...

The prevalence of Helicobacter pylori is increased in healthcare workers and in intensive care nurses. Exposure to H. pylori from gastric secretions and faeces are probably the main sources of transmission to healthcare workers. Routine use of selective decontamination of digestive tract (SDD) in an intensive care unit suppresses H. pylori in critically ill patients. It was questioned whether t...

Introduction: DFEs have been widely used to remove intersymbol interference from the data received through communication channels [1]. In situations where blind adaptation of DFEs is required, algorithms based on the constant modulus criterion [2] for joint updating of the feedforward and feedback filters may converge to degenerated solutions. This occurs when the signal at the equalizer output...

BACKGROUND Vulnerable plaque demonstrates intense inflammation in which macrophages secrete matrix metalloproteinases (MMPs) that degrade the fibrous cap, ultimately leading to rupture, in situ thrombosis, and an associated clinical event. Thus, inhibition of MMP activity or more general suppression of vascular inflammation are attractive targets for interventions intended to reduce plaque rupt...
