Manila clams (Ruditapes philippinarum) and sediments were collected bimonthly during 2007 at five locations in Jiaozhou Bay near Qingdao, China, to determine heavy metal concentrations and to assess the validation of R. philippinarum as a metal biomonitor. Concentrations of heavy metals in clam soft tissues ranged between 0.75 and 3.31, 0.89 and 15.20, 5.70(More)
Standard Hidden Markov Model (HMM) assumes that successive observations are independent to one another given the state sequence. This leads to a poor trajectory model for speech. Many explicit trajectory modeling techniques have been studied in the past to improve trajectory modeling for HMM. However, these techniques do not yield promising improvements(More)
Recently, context-dependent Deep Neural Network (CD-DNN) has been found to significantly outperform Gaussian Mixture Model (GMM) for various large vocabulary continuous speech recognition tasks. Unlike the GMM approach, there is no meaningful interpretation of the DNN parameters, which makes it difficult to devise effective adaptation methods for DNNs.(More)
Development of highly cost-effective, highly operation-convenient and highly efficient natural polymer-based adsorbents for their biodegradability and biocompatibility, and supply of safe drinking water are the most threatening problems in water treatment field. To tackle the challenges, a new kind of efficient recyclable magnetic chitosan/cellulose hybrid(More)
OBJECTIVE To study the clinical features and conservative treatment of petrositis. METHOD One case of petrositis was reported and literatures were reviewed. Opacificated air cells in CT, and anomalous, discontinuous hypersignal in MRI T1 and T2 provided evidence of infection of the apex of the petrous temporal bone. RESULT The patient recovered totally(More)
Hydroxyethylcellulose (HEC) was synthesized by a fully homogenous method from cellulose in 7.5 wt.-% NaOH/11 wt.-% urea aqueous solutions under mild conditions. HEC samples were characterized with NMR, SEC-LLS, solubility, and viscosity measurements. The MS and DS values of the obtained HEC samples are in the range from 0.54 to 1.44 and 0.45 to 1.14,(More)
A facile approach was investigated to encapsulate and protect curcumin (Cur) by self-assembly of lysozyme (Ly) and carboxymethylcellulose (CMC) of different degrees of substitution (DSs). This work studied the influence of Ly-CMC coacervates on the binding, solubility and stability of Cur. The interactions of Cur with Ly-CMC coacervates were researched by(More)
Nanostructured cellulose nanofibrils can form ductile or tough networks that are suitable templates for the creation of materials with functional properties. In this work, a facile method has been developed for the preparation of magnetic hybrid cellulose aerogels. The preparation processes followed by two steps, firstly, preparation of cellulose hydrogel(More)
A pH-responsive system by constructing a designable coordination bonding-based metal-tannic acid (TA) architecture on zein nanoparticles (NPs) has been investigated. Film formation was initiated by the adsorption of the polyphenol and directed by pH-dependent, multivalent coordination bonding. The prepared metal-TA coated zein NPs (zein-TA/metal NPs)(More)
