Ferrocene-modified DNA probes formed fully matched duplexes and bulge-containing ones with wild-type and insertion/deletion-type complements of clinical importance, respectively. Cyclic voltammetry measurements revealed that the bulge-containing duplexes showed an increased flexibility compared to the fully matched duplexes. The difference in the bending elasticity could be read out electrochem...

We propose a new algorithm for fast Fourier transforms. This algorithm features uniformly long vector lengths and stride one data access. Thus it is well adapted to modern vector computers like the Fujitsu VP2200 having several oating point pipelines per CPU and very fast stride one data access. It also has favorable properties for distributed memory computers as all communication is gathered t...

In recent times, DSP algorithms have received increased attention due to rapid advancements in multimedia computing and high-speed wired and wireless communications. In response to these advances, the search for novel implementations of arithmetic-intensive circuitry has intensified. For the portability requirement in telecommunication systems, there is a need for low power hardware implementat...

In this paper we focus our attention on a particle that follows a unidirectional quantum walk, an alternative version of the currently widespread discrete-time quantum walk on a line. Here the walker at each time step can either remain in place or move in a fixed direction, e.g., rightward or upward. While both formulations are essentially equivalent, the present approach leads us to consider d...

A Green's function solution is derived for calculating the acoustic field generated by phased array transducers of arbitrary shape when driven by a single frequency continuous wave excitation with spatially varying amplitude and phase. The solution is based on the Green's function for the homogeneous wave equation expressed in the spatial frequency domain or k-space. The temporal convolution in...

Recently introduced novel voltammetric and chronoamperometric techniques, derived from square-wave voltammetry (SWV), are being studied for their analytical utility. Three protocols, namely potential-corrected, multi-sampled, cumulative voltammetry, along with chronoamperometry (also known as electrochemical Faradaic spectroscopy), described analytically tested. The evaluation is based on both ...

In this paper, a modified expanded graphite composite electrode based on natural zeolitic volcanic tuff modified with silver (EG-Ag-Z-Epoxy) was developed. Cyclic voltammetry measurements revealed a reasonably fast electron transfer and a good stability of the electrode in 0.1 M NaOH supporting electrolyte. This modified electrode exhibited moderate electrocatalytic effect towards urea oxidatio...
