Last years, Wavelet Packet Modulation (WPM) or Wavelet Packet Transform based Orthogonal Frequency Division Multiplexing (WPT-OFDM) have been introduced to wired and wireless communication fields as efficient Multicarrier Modulation (MCM) techniques. The wavelets have interesting features such as flexibility, compatibility and localization in both time and frequency domains with no need to use ...

The specialized type III secretion (T3S) apparatus of pathogenic and symbiotic Gram-negative bacteria comprises a complex transmembrane organelle and an ATPase homologous to the F1-ATPase beta subunit. The T3S ATPase HrcN of Pseudomonas syringae associates with the inner membrane, and its ATP hydrolytic activity is stimulated by dodecamerization. The structure of dodecameric HrcN (HrcN12) deter...

A gold nanoparticle, localised plasmon array biosensor using light scattering has been employed in the detection of allergen-specific antibodies in whole blood and sera. The array sensor was functionalized with four different allergens, cat dander (Fel d1), dust mite (Der p1), peanut allergen (Ara h1) and dog dander (Can f1) and immuno-kinetic assay was performed to detect their respective anti...

We study the spectrum of solvable string models on plane waves descending from non-conformal Dp-brane geometries. We mainly focus on S-dual F1/D1-waves in type IIB and type I/heterotic 10D superstrings. We derive the Kaluza-Klein spectrum of N = 1, 2 10D supergravities on D1/F1-waves. We compute helicity supertraces counting multiplicities and R-charges of string excitations in the plane wave g...

Repeated extraction of bovine heart submitochondrial particles with ammonia and EDTA (AE) yields a preparation that is highly deficient in coupling factor B (FB). The activity of the thrice extracted particle (AE-P3) in ATP-driven NAD+ reduction by succinate and the 32Pi-ATP exchange activity were substantially stimulated, 8-fold and 5-fold, respectively, by purified FB. To decrease the basal a...

The bacterial RecA protein has been the most intensively studied enzyme in homologous genetic recombination. The core of RecA is structurally homologous to that of the F1-ATPase and helicases. Like the F1-ATPase and ring helicases, RecA forms a hexameric ring. The human Dmc1 (hDmc1) protein, a meiosis-specific recombinase, is homologous to RecA. We show that hDmc1 forms octameric rings. Unlike ...

We introduce various exchange interactions in a model Hamiltonian for Ce3+ ions in cubic symmetry with three configurations (f0,f1,f2). With the impurity pseudo spin SI = 1/2, our Hamiltonian includes: (i) One-channel Sc = 1/2 Anderson model; (ii) Two-channel Sc = 1/2 Anderson model; (iii) An unforseen one-channel Sc = 3/2 Anderson model with a non-trivial fixed point; (iv) Mixing exchange inte...

The speech parameters, most commonly used nowadays, are Cepstral coefficients derived from FFT or LPC Spectrum. An alternative approach that can potentially provide maximum speaker and channel independence is estimation of articulatory based features such as formant frequencies, amplitudes and voicing degree. A present report describes a new method and algorithm of robust estimation of F1(t), F...

Oligomycin sensitivity-conferring protein (OSCP) is a water-soluble subunit of bovine heart mitochondrial H(+)-ATPase (F1-F0). In order to investigate the requirement of OSCP for passive proton conductance through mitochondrial F0, OSCP-depleted membrane preparations were obtained by extracting purified F1-F0 complexes with 4.0 M urea. The residual complexes, referred to as UF0, were found to b...
