In this paper, we propose a new wideband speech coder which combines the European standard of a narrowband speech coder, i.e., GSM-EFR, and a transform coder using the discrete wavelet transform. Input speech is first split into two bands with equal bandwidth. A subband coder with wavelet transformed speech is designed for a upper band coder, and a GSM-EFR coder is adopted as a lower band coder...

A simple and efficient procedure for the industrial preparation of akebia saponin D, one of the bioactive compounds commonly found in the well-known Chinese Medicinal herb Dipsaci Radix, was developed. First, HPD-722 was selected from among 10 kinds of macroporous absorption resins. Following this step, the purity of akebia saponin D was increased about 10 times from 6.27% to 59.41%. In order t...

We present a high-resolution multi-frequency study of the Small Magellanic Cloud (SMC) region around the X-ray pulsar AX J0105-722. From ROSAT PSPC images we resolve this source into several X-ray sources. We combine X-ray, radio-continuum and optical data to identify the sources: for RX J0105.1-7211 we propose an emission line star from the catalogue of Meyssonier & Azzopardi (1993) in the X-r...

Abstract Introduction Heart failure is a frequent death cause for oncological patients who received treatment with doxorubicin (DOX). DOX administration inhibits autophagy in cardiomyocytes and causes myocardial damage. Natural activators of (NAA) such as trehalose, natural disaccharide, spermidine, putrescine-derived polyamine initially isolated from semen, were previously found to be promisin...
