Speech has been embedded into many applications like speech recognition, development of hearing aid, VoIP, mobile and other forms of personal communication. Speech enhancement techniques have been widely used for minimizing undesirable background noises. This paper deals with single channel speech enhancement techniques based on Spectral Subtraction (SS), Wavelet Transform (WT) and Adaptive Wie...

Limiting currents for the reduction of hexacyanoferrate-(III), i(lim), in aqueous solutions have been recorded in the presence of convective flow generated by a focused acoustic source with its main axis placed normal to the surface of a circular Au electrode embedded in a coplanar Teflon shroud. The results obtained could be fitted to a formula of the type -i(lim) = a(Uz(ss))b, where Uz(ss) is...

The pediatric glaucomas present some of the greatest clinical challenges. Uveitic glaucoma is a pathology whose causes and treatment are still a great enigma to all glaucoma specialists. We describe the spectrum of pediatric uveitic glaucoma along with its risk factors and the outcome of treatment in this subgroup. Our paper aims to review the existing literature on the subject and throw light ...

For a prime p, a proper subgroup H of the finite group G is strongly p-embedded in G if p divides |H| and p does not divide |H ∩ H| for all g ∈ G \H . A characteristic property of strongly p-embedded subgroups is that NG(X) ≤ H for any non-trivial p-subgroup X of H . Strongly p-embedded subgroups appear in the final stages of one of the programmes to better understand the classification of the ...

The occurrence of large cell transformation has been well documented in a subgroup of patients with mycosis fungoides/Sezary syndrome (MF/SS). However, because of the rarity of MF/SS, little is known about the influence of clinicopathologic features in predicting large cell transformation and about outcome in the transformed cases. We evaluated all patients with MF/SS who were registered in our...

A novel audio watermarking scheme based on frequency-selective spread spectrum (FSSS) technique is presented. Unlike most of the existing spread spectrum (SS) watermarking schemes that use the entire audible frequency range for watermark embedding, the proposed scheme randomly selects subband(s) signal(s) of the host audio signal for watermark embedding. The proposed FSSS scheme provides a natu...

The objective of this study was to visualize borreliae directly in whole-body sections of Ixodes ricinus by fluorescence in situ hybridization (FISH). Borrelia afzelii mono-infected or Borrelia burgdorferi sensu stricto (ss)/B. afzelii double-infected nymphs were fixed, embedded in cold polymerizing resin and sectioned. The same sample processing was applied to skin biopsies taken from a Mongol...

Spread spectrum (SS) watermarking has proven to be efficient, robust and cryptographically secure. Each bit of watermark information is embedded over wide spectrum of the host signal based on spectrum spreading concept of SS modulation in digital communication and can easily be integrated with many existing data transmission scheme. This has made SS watermarking method more attractive during re...

Abstract Background Chest computed tomography (CT) findings provide great added value in characterizing the extent of disease and severity pulmonary involvements. CT score (CT-SS) could be considered as an appropriate prognostic factor for mortality prediction patients with COVID-19 pneumonia. In this study, we performed a meta-analysis evaluating accuracy CT-SS Methods A systematic search was ...
