Rate of decay of s-numbers
For an operator T ∈ B(X, Y ), we denote by am(T), cm(T), dm(T), and tm(T) its approximation, Gelfand, Kolmogorov, and absolute numbers. We show that, for any infinite dimensiona...

The maximum number of halving lines and the rectilinear crossing number of Kn for n
For n 27 we present exact values for the maximum number h(n) of halving lines and h(n) of halving pseudolines, determined by n points in the plane. For this range of values of n ...

Extended Spiking Neural P Systems with Decaying Spikes and/or Total Spiking
We consider extended variants of spiking neural P systems with decaying spikes (i.e., the spikes have a limited lifetime) and/or total spiking (i.e., the whole contents of a neuro...

The Evolution and Decay of Statically Detected Source Code Vulnerabilities
The presence of vulnerable statements in the source code is a crucial problem for maintainers: properly monitoring and, if necessary, removing them is highly desirable to ensure h...

Analysis of Musical Instrument Sounds by Source-Filter-Decay Model
This paper proposes a way of modelling the time-varying spectral energy distribution of musical instrument sounds. The model consists of an excitation signal, a body response fil...
