Pulsed-field gel electrophoresis (PFGE) has been the typing method of choice for strain identification in epidemiological studies of several bacterial species of medical importance. The usual procedure for the comparison of strains and assignment of strain type and subtype relies on visual assessment of band difference number, followed by an incremental assignment to the group hosting the most ...

This paper is concerned with radio resource allocation in multiple-chip-rate (MCR) DS/CDMA systems accommodating multimedia services with di erent information rates and quality requirements. Considering power spectral density (PSD) over a radio frequency (RF) band and the effect of RF input ltering on the receiver in MCR-DS/CDMA systems, we present criteria for capacity estimation and clarify t...

In this paper, we compare two signal designs for uplink quasi-synchronous code division multiple access (CDMA) channels in order to optimize the trade-off between bandwidth efficiency and power efficiency. The design we call band-limited DS/CDMA design, is based on the time-domain assignment of Gold sequences, just as in the ordinary DS/CDMA, but with band-constrained cyclic chip interpolation ...

12 We discuss the use of resonant photoemission in the study of rare earth/transition metal perovskites and perovskite-related structures. We illustrate its application to the assignment of the RE and TM valence band density of states in Nd2Ni1−xCuxO4 and REBaCo2O5+δ. In both cases, the relative positions of the 4f and 3d contributions within the valence band density of states (DOS) relative to...

Channel assignment mechanisms in dynamic spectrum access (DSA) networks are often designed without accounting for adjacent-channel interference (ACI) between different secondary users (SUs). To prevent such interference, guard-bands are needed between channels that are assigned to different SUs. However, introducing guard-bands restricts the spectrum efficiency. In this paper, we consider the p...

The Huggins band of ozone is investigated by means of dynamics calculations using a new (diabatic) potential energy surface for the 3 (1)A'(1B2) state. The good overall agreement of the calculated spectrum of vibrational energies and intensities with the experimental spectrum, especially at low to intermediate excitation energies, is considered as evidence that the Huggins band is due to the tw...

Spectrum sensing is a fundamental operation in cognitive radio environment. It gives information about spectrum availability by scanning the bands. Usually a fixed amount of time is given to scan individual bands. Most of the times, historical information about the traffic in the spectrum bands is not used. But this information gives the idea, how busy a specific band is. Therefore, instead of ...

We study spectrum allocation for terahertz (THz) band communication (THzCom) systems, while considering the frequency and distance-dependent nature of THz channels. Different from existing studies, we explore multi-band-based with adaptive sub-band bandwidth (ASB) by allowing interest to be divided into sub-bands unequal bandwidths. Also, investigate impact assignment on multi-connectivity (MC)...

The normal modes have been calculated for structures having the dihedral angles of the four @-turns of insulin. Frequencies are predicted in the amide I region near 1652 and 1680 cm-’. The former overlaps the a-helix band at 1658 cm-l in the Raman spectrum, while the latter accounts for the hitherto unassignable band a t 1681 cm-’. Calculated amide I11 frequencies extend above 1300 cm-I, provid...
