A support vector machine is a new learning machine; it is based on the statistics learning theory and attracts the attention of all researchers. Recently, the support vector machines SVMs have been applied to the problem of financial early-warning prediction Rose, 1999 . The SVMs-based method has been compared with other statistical methods and has shown good results. But the parameters of the ...

This study evaluated if the Aedes aegypti population in the city of Cali, Colombia was composed of genetically distinct local populations with different levels of insecticide resistance and dengue vector competence. Insecticide resistance was assayed biochemically and was associated with varying levels of mixed-function oxidases and non-specific esterases. The genes encoding those enzymes were ...

Background: Electrocardiogram (ECG) is defined as an electrical signal, which represents cardiac activity. Heart rate variability (HRV) as the variation of interval between two consecutive heartbeats represents the balance between the sympathetic and parasympathetic branches of the autonomic nervous system.Objective: In this study, we aimed to evaluate the efficiency of discrete wavelet transfo...

Different approaches have been proposed for feature selection to obtain suitable features subset among all features. These methods search feature space for feature subsets which satisfies some criteria or optimizes several objective functions. The objective functions are divided into two main groups: filter and wrapper methods.  In filter methods, features subsets are selected due to some measu...

Due to their error-prone replication, RNA viruses typically exist as a diverse population of closely related genomes, which is considered critical for their fitness and adaptive potential. Intra-host demographic fluctuations that stochastically reduce the effective size of viral populations are a challenge to maintaining genetic diversity during systemic host infection. Arthropod-borne viruses ...

Genetic transformation studies were carried out to standardize a protocol for Agrobacterium -mediated genetic transformation of three economically important strawberry (Fragaria x ananassa Duch) cultivars Kurdistan’, Camarosa’, and ‘Paros’. Shoot regeneration frequency 72, 65 and 30% was obtained on MS (1) basal medium supplemented with 2% glucose and 4 mg/l TDZ for Camarosa, Kurdistan and Paro...

background: uropathogenic escherichia coli (upec) are major bacterial agent of urinary tract infection (uti). this infection is more prevalent among women because approximately half of all women will experience a uti in their life-time and near a quarter of them will have a recurrent infection within 6–12 months. iuta protein has a major role during upec pathogenesis and consequently infection....

background: leishmaniasis is important vector-borne parasitic disease worldwide, caused by the genus leishmania . the objective of the current study was to identify genetic polymorphism in l. major , one of the species causing cutaneous leishmaniasis (cl), isolated from southeastern iran, using permissively primed intergenic polymorphic-polymerase chain reaction (ppip-pcr) method. methods: over...
