Quantification of pulmonary pressure-volume (P-V) curves is often limited to calculation of specific compliance at a given pressure or the recoil pressure (P) at a given volume (V). These parameters can be substantially different depending on the arbitrary pressure or volume used in the comparison and may lead to erroneous conclusions. We evaluated a sigmoidal equation of the form, V = a + b[1 ...

A reanalysis of data drawn by Hartshorne, Tenenbaum, and Pinker (2018) from two-thirds a million English speakers showed that their overall conclusion one sharply defined critical age at 17.4 for all language learners is based on artificial results. We show instead discontinuous exponential learning with sigmoidal decay (ELSD) model, continuous ELSD model had better fit when applied separately ...

The modified sigmoidal bacteria growth functions (the Gompertz, logistic, and Richards) were used to evaluate the methane production process kinetics of agricultural wastes. mesophilic anaerobic co-digestion experiments conducted with various wastes as feedstocks, including cow manure, corn straw, grape leaves, vines, wine residue, strawberry tomato leaves. results showed that manure other incr...

UNLABELLED The qpcR library is an add-on to the free R statistical environment performing sigmoidal model selection in real-time quantitative polymerase chain reaction (PCR) data analysis. Additionally, the package implements the most commonly used algorithms for real-time PCR data analysis and is capable of extensive statistical comparison for the selection and evaluation of the different mode...

WASHINGTON (AP) — Democrats promised Thursday to speed an economic recovery package through Congress, but vowed to rearrange President Bush’s budget proposal to ben­ efit m iddle-income Americans, not the rich. “ Democrats w ill not obstruct, but we w ill try to improve the p re s id e n t’s p acka ge ,” sa id House Majority Leader Richard Gephardt, D-Mo., as the Budget Committee began hearings...

Bill Horne MakeWaves, Inc. 832 Valley Road Watchung, NJ 07060 We present a computationally efficient algorithm for function approximation with piecewise linear sigmoidal nodes. A one hidden layer network is constructed one node at a time using the method of fitting the residual. The task of fitting individual nodes is accomplished using a new algorithm that searchs for the best fit by solving a...

The activity is related to the mineralogy and geological history of clays. Soils with same value liquidity limit or plasticity index can have very different characteristics depending on amount type clay minerals. methylene blue characterizes clays reflects surface activity. Ten inactive soils contain minerals (kaolinite, illite), these absorb little water. Two swelling normal are composed illit...

This letter proposes a new type of neurons called multithreshold quadratic sigmoidal neurons to improve the classification capability of multilayer neural networks. In cooperation with single-threshold quadratic sigmoidal neurons, the multithreshold quadratic sigmoidal neurons can be used to improve the classification capability of multilayer neural networks by a factor of four compared to comm...

We adopted a person–organization (P–O) fit framework to examine applicant attraction to an organization in the context of Web-based recruitment. A total of 121 undergraduate business students participated in a two-stage study first by completing a paper-and-pencil survey and second, by visiting a fictitious recruitment Web site in which the researchers manipulated the fit feedback information p...
