Conventional methods of quadrature phase-shifting holography require two holograms and either intensity distribution of the reference wave or that of the object wave to reconstruct an original object without the zero order and the twin-image noise in an on-axis holographic recording setup. We present a technique called two-step-only quadrature phase-shifting holography in which solely two quadr...

The question of the state-size cost for simulation of two-way nondeterministic automata (2nfas) by two-way deterministic automata (2dfas) was raised in 1978 and, despite many attempts, it is still open. Subsequently, the problem was attacked by restricting the power of 2dfas (e.g., using a restricted input head movement) to the degree for which it was already possible to derive some exponential...

It is shown that the zero range limit of the Karlsson-Zeiger equations uniquely define unitary three particle amplitudes using only the observable phase shifts and binding energies of the two particle subsystems.

The paper presents several results on edge partitions and vertex partitions of graphs into graphs with bounded size components. We show that every graph of bounded tree-width and bounded maximum degree admits such partitions. We also show that an arbitrary graph of maximum degree three has a vertex partition into two graphs, each of which has components on at most two vertices, and an edge part...

This paper concerns the image reconstruction from a few projections in Computed Tomography (CT). The main objective of this paper is to show that the problem is so ill posed that no classical method, such as analytical methods based on inverse Radon transform, nor the algebraic methods such as Least squares (LS) or regularization theory can give satisfactory result. As an example, we consider i...

We apply quantum control techniques to a long spin chain by acting only on two qubits at one of its ends, thereby implementing universal quantum computation by a combination of quantum gates on these qubits and indirect SWAP operations across the chain. It is shown that the control sequences can be computed and implemented efficiently.We discuss the application of these ideas to physical system...

In this paper, we use a single current differencing buffer amplifier (CDBA) in the current mode with application of voltage mode universal filter and all pass filter is presented. The proposed circuit is suitable for realize the proposed operation by using of two CDBA with the current processing application of filter design also we have driven the performance of CDBA. All-pass filter & Universa...

In this paper we present a new voltage-mode (VM) multifunction filter configuration using only two four terminal floating nullors (FTFNs) and five passive elements. The circuit with a single input and three outputs can simultaneously realise lowpass (LP), bandpass (BP) and highpass (HP) filter responses. The natural frequency ( 0 ω ) and the bandwidth ( /Q ω0 ) can be orthogonally controlled. T...

Two-bottle tests have been used extensively to measure the preference for taste and nutrient solutions but there has been little work with tests involving more than two bottles. Here, we compare the results obtained in two-bottle tests with those obtained in three- and six-bottle tests. In Experiment 1, we measured the preferences for 2 mM saccharin, 50 mM citric acid, 0.3 mM quinine hydrochlor...

INTRODUCTION The firing behavior of spinal motoneurons is controlled by a complex interplay between the synaptic inputs that they receive and the intrinsic properties of motoneurons. In particular, the longlasting afterhyperpolarization which follows each motoneuron spike was found to be an important mechanism in the regulation of repetitive firing behavior (Kernell, 1965, 2006). As a result, m...
