Pooling multiple swab samples before RNA extraction and real-time reverse transcription polymerase chain reaction (RT-PCR) analysis has been proposed as a strategy to reduce costs increase throughput of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tests. However, reports on practical large-scale group testing for SARS-CoV-2 have scant. Key open questions concern reduced sensitivity due sample dilution, the rate false positives, actual efficiency (number tests saved by...

Abstract In recent years process simulation by computer has become an accepted tool in the design and control of chemical processes, but there are still uncertainties conflicting views about real benefits relative to cost both industry education. This article surveys literature last three years, exploring answers question: How fulfilled expectations education what major areas research identifiable at this time? It is concluded that remains a very dynamic field with continuous expansion...

Abstract The numerical solution of n non‐linear algebraic equations with unknowns, when any or all the variables are subjected to constraints, is discussed. Distinction made between physical and absolute constraints. It shown, using a set test problems, that constrained does require special approach. found step length restricted Newton's method performs best for problems Physical constraints can be handled continuation penalty functions.

Data transformation for obtaining the most accurate and statistically valid correlation is discussed. It shown that degree of a polynomial used in regression limited by collinearity among monomials. The significance can best be measured truncation to natural error ratio. representing highest power term lower polynomial, due precision experimental data. Several transformations reducing are introduced. use orthogonal polynomials provides an estimation ratio on basis range independent variable...

Abstract Regression of the experimental data one independent variable, y vs . a linear combination functions an variable form = Σβ j f (x) is considered. Inherent collinearity among terms such may prevent obtaining model desired accuracy. Traditional indicators, condition number normal matrix, variance inflation factor, and new indicator (truncation‐error‐to‐noise ratio) are used to investigate effects range precision independent‐variable on in regression model. Statistical confidence...

Prediction of unknown properties for a target compound using quantitative structure−property relationships (QSPRs) is reliable only if the within model applicability domain. To improve prediction reliability, "targeted" QSPR (TQSPR) method developed in which training set containing compounds structurally similar to first identified. Similarity measured by partial correlation coefficients between vectors molecular descriptors and each potential predictive compound. Available property data are...

Abstract A new approach for predicting a wide range of physical and thermodynamic properties is proposed. It involves calculation the molecular descriptors target compound unknown properties, followed by regression this vector vs. database compounds with known measured properties. The model, obtained in terms predictive their coefficients, then used prediction compound. precision can be estimated from standard deviation correlation property data compounds. proposed method was tested 31 18...
