Clustering is an important data exploration task. A prominent clustering algorithm is agglomerative hierarchical clustering. Roughly, in each iteration, it merges the closest pair of clusters. It was rst proposed way back in 1951, and since then there have been numerous mod-iications. Some of its good features are: a natural, simple, and non-parametric grouping of similar objects which is capab...

PURPOSE This study compared the performance of 3 admission prognostic scores in predicting hospital mortality. MATERIALS AND METHODS Patient admission characteristics and hospital outcome of 9549 patients were recorded prospectively. The discrimination and calibration of the predicted risks of death derived from the Simplified Acute Physiology Score (SAPS III), Admission Mortality Prediction ...

Dental and dental hygiene faculty members often do not provide consistent instruction in the clinical environment, especially in tasks requiring clinical judgment. From previous efforts to calibrate faculty members in calculus detection using typodonts, researchers have suggested using human subjects and emerging technology to improve consistency in clinical instruction. The purpose of this pil...

BACKGROUND Although several risk factors for acute kidney injury (AKI) have been identified, early detection of AKI in acute decompensated heart failure patients remains a challenge. The aim of this study was to develop and validate a risk score for early prediction of AKI in acute decompensated heart failure patients. METHODS AND RESULTS A total of 676 consecutive acute decompensated heart f...

The change of two orders of magnitude in the new DCF of SRE’10, relative to the old DCF evaluation criterion, posed a difficult challenge for participants and evaluator alike. Initially, participants were at a loss as to how to calibrate their systems, while the evaluator underestimated the required number of evaluation trials. After the fact, it is now obvious that both calibration and evaluat...

A field investigation was undertaken during Kharif (June–September) 2019 at Agriculture Research Institute, Professor Jayashankar Telangana State University, Rajendranagar, Hyderabad, Telengana State, India with an object to evaluate the CROPGRO-Tomato model under different dates of planting and cultivars.The experiment carried out (02nd Jul, 12th 22nd 02nd Aug, 11th 23rd 03rd Sep 13th Sep) as ...

The calibration-free laser-induced breakdown spectroscopy (CF-LIBS) technique requires no reference samples of the same matrix to establish calibration curve, not affected by effect. In recent years, CF-LIBS technology has greatly progressed, and accuracy quantitative analysis gradually improved. purpose this review was introduce fundamental modified algorithms. Boltzmann plot method, Saha–Bolt...

The rapid growth of interest in the field of ion-selective electrodes (ISEs), within the larger field of electrochemical sensors based on potentiometric, amperometric, and conductometric principles, makes it highly desirable to achieve improved standardization of nomenclature in this area. The previous document, W A C Recommendations 1975 (1) has been corrected using recent experimental and the...

A new, simple, precise and accurate high performance thin layer chromatographic method has been proposed for the determination of almotriptan malate in a tablet dosage form. The drug was separated on aluminum plates precoated with silica gel 60 GF(254) with butanol:acetic acid:water (3:1:1) was used as mobilephase. Quantitative analysis was performed by densitometric scanning at 300 nm. The met...
