Spectral clustering is a key research topic in the field of machine learning and data mining. Most of the existing spectral clustering algorithms are built upon Gaussian Laplacian matrices, which are sensitive to parameters. We propose a novel parameter-free, distanceconsistent Locally Linear Embedding (LLE). The proposed distance-consistent LLE promises that edges between closer data points ha...

Electromembrane extraction (EME) of the polar zwitterionic drugs, anthracyclines (ANT, doxorubicin, daunorubicin and its metabolite daunorubicinol), from rabbit plasma was investigated. The optimized EME compared to conventional sample pretreatment techniques such as protein precipitation (PP) liquid-liquid (LLE), mainly in terms reliability, recovery matrix effect. In addition, phospholipids p...

Prostate and bladder cancers are the two prevalent urological cancers, several therapeutic options currently available but outcomes have not been satisfactory. To find better option, we investigated if bioactive extracts of monk fruit, mogrosides, with potential anticancer activity might effect against prostate cancer cells. Four commercial products made mogrosides known as Lakantoò (LKT) produ...

Automatic head frontal-view identification is challenging due to appearance variations caused by pose changes, especially without any training samples. In this paper, we present an unsupervised algorithm for identifying frontal view among multiple facial images under various yaw poses (derived from the same person). Our approach is based on Locally Linear Embedding (LLE), with the assumption th...

Dimensionality reduction methods for visualization map the original high-dimensional data typically into two dimensions. Mapping preserves the important information of the data, and in order to be useful, fulfils the needs of a human observer. We have proposed a self-organizing map (SOM)based approach for visual surface inspection. The method provides the advantages of unsupervised learning and...

We consider the nonlinear stability of spectrally stable periodic waves in Lugiato-Lefever equation (LLE), a damped Schrodinger with forcing that arises optics. So far, such solutions has only been established against co-periodic perturbations by exploiting existence spectral gap. In this paper, we which are localized, i.e., integrable on line. Such localized naturally yield absence gap, so mus...

A method based on the Genetic Algorithm (GA) was developed to study the phase behavior of multicomponent and multiphase systems. Upon application of the GA to the thermodynamic models which are commonly used to study the VLE, VLLE and LLE phase equilibria, the physically meaningful values for the Binary Interaction Parameters (BIP) of the models were obtained. Using the method proposed in t...
