We develop a statistical method to infer the parameters of Hubbell's neutral model of biodiversity using data on local species abundances and their phylogenetic relatedness. This method uses the approximate Bayesian computation (ABC) approach, where the data are summarized into a small number of informative summary statistics. We used three statistics: the number of species in the sample, Shann...

In the basic Artificial Bee Colony (ABC) algorithm, if the fitness value associated with a food source is not improved for a certain number of specified trials then the corresponding bee becomes a scout to which a random value is assigned for finding the new food source. Basically, it is a mechanism of pulling out the candidate solution which may be entrapped in some local optimizer due to whic...

In this work, we successfully developed a process to fabricate dual-channel polymeric waveguide filters based on an asymmetric Bragg coupler (ABC) using holographic interference techniques, soft lithography, and micro molding. At the cross- and self-reflection Bragg wavelengths, the transmission dips of approximately -16.4 and -11.5 dB relative to the 3 dB background insertion loss and the 3 dB...

Many clinical studies have reported that irinotecan has reproducible antitumor activity against lung cancer. Both cisplatin and SN-38 are key drugs in the treatment of lung cancer, and their combination is one of the most promising regimens available. Using lung cancer cell lines, ABC-1 and SBC-3, we examined the cytotoxic effect of the schedule, as well as the effect of cisplatin on topoisomer...

The major aim of this study is to extend Zhang and Isa’s (2011) study by investigating the moderating effect of the stages of ABC application on the firms’ performance. This study selects 106 Chinese manufacturing companies and employs multiple regression technique and structural equation modelling. It examines whether successful application of the ABC directly affects the firm’s performance, a...

BACKGROUND Knowledge of adipose composition in relation to mortality may help delineate inconsistent relationships between obesity and mortality in old age. We evaluated relationships between abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) density, mortality, biomarkers, and characteristics. METHODS VAT and SAT density were determined from computed tomography sca...

introduction: aneurysmal bone cysts (abc) are extremely rare in the head and neck region and even rarer in sinuses.  abc is a benign multicystic mass that is locally-destructive and rapidly expandable. hemorrhagic fluid content (like in this case) and septated appearance are the characteristic feature of abc. established treatment options for abcs include sclerotherapy, embolization, radiothera...
