In many application domains, classification tasks have to tackle multiclass imbalanced training sets. We have been looking for a CBA approach (Classification Based on Association rules) in such difficult contexts. Actually, most of the CBA-like methods are one-vs-all approaches (OVA), i.e., selected rules characterize a class with what is relevant for this class and irrelevant for the union of ...

12 In a single-electrode current clamp recording, the measured potential includes both the 13 response of the membrane and that of the measuring electrode. The electrode response is 14 traditionally removed using bridge balance, where the response of an ideal resistor representing 15 the electrode is subtracted from the measurement. Because the electrode is not an ideal resistor, 16 this proced...

Least squares kinetic upwind mesh-free (LSKUM) method has been the subject of research over twenty years in our research group. LSKUM method requires a cloud (W) of points or nodes and connectivity N(P 0 ) for every 0 P Î W . The connectivity of P0 is a set of neighbours 0 ( ) i P N P Î of P0. The cloud can be a simple cloud, Cartesian cloud or chimera cloud or can be obtained rapidly using adv...

The calibration method is used to identify some minimizers of the Mumford-Shah functional. The method is then extended to more general free discontinuity problems.

Rapid and convenient biosensing platforms could be beneficial to timely diagnosis and treatment of diseases in virtually any care settings. Sandwich immunoassays, the most commonly used methods for protein detection, often rely on expensive tags such as enzyme and tedious wash and incubation procedures operated by skilled labor. In this report, we revolutionized traditional sandwich immunoassay...

In the first part of this research, extensive speciesdependent cyanide recoveries studies were performed using the approved standard methods available for determination of free cyanide. The data obtained show that serious problems are associated with both the CATC (cyanide amenable to chlorination) and WAD (weak and dissociable cyanide) methods. In the second part, a novel flow injection gas-di...

A robust method for pricing options at strikes where there is not an observed price is a vital tool for the pricing, hedging, and risk management of derivatives. All institutions that trade derivatives will have an approach to this task. Typical examples might be a simple interpolation scheme across implied volatilities, or the use of a modelbased formula optimized to fit observed prices. It is...

A truly meshfree method – the radial basis function collocation method is implemented for some 2-D and 3-D groundwater models. The results showed the superior simplicity, general applicability and accuracy of this method, which is a very promising simulation tool in many application areas.
