food safety is considered as an important world concern. the detection of pathogen and toxic materials in food has an important role in public health care. in recent years, the applications of microbial biosensor have been developed as a new approach for toxicity control. luminescent microbial biosensor is an appropriate biological tool for protection of natural environment. this type of biosen...
background several empirical studies have shown the attitude of smokers to formulate judgments based on distortion in the risk perception. this alteration is produced by the activation of the optimistic bias characterized by a set of the unrealistic beliefs compared to the outcomes of their behavior. this bias exposes individuals to adopt lifestyles potentially dangerous for their health, under...
Background : Line bisection test is used for detecting inattention. In this test normal people usually show a rightward bias which indicates right hemisphere dominancy for visuo-spatial attention processing. The performance of people with Attention deficit/Hyperactivity Disorder (ADHD) in these kinds of visuo-spatial tests is different from normal people. The difference could be as a result o...
the one photon absorption (opa) cross section of a current carrying two-orbital quantum dot (qd) with strong electron-phonon interaction (polaron regime) is considered. using the self-consistent non-equilibrium hartree-fock (hf) approximation, we determine the dependence of opa cross section on the applied bias voltage, the strength of effective electron-electron interaction, and level spacing ...
This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...
Codon bias refers to the differences in the frequency of occurrence of synonymous codons in coding DNA. Pattern of codon and optimum codon utilization is significantly different between the lives. This difference is due to the long term function of natural selection and evolution process. Genetics drift, mutation and regulation of gene expression are the main reasons for codon bias. In this stu...
Williams, Watts, Macleod and Mathews' (1988) model of anxiety and depression leads to the prediction that anxious patients will show mood – congreuent implicit memory bias, while depressed patients will show mood-congruent explicit memory bias.Although this prediction has been supported by some researchers (Denny & Hunt, 1992 mathews, Moog, et al , 1989 watkins, et al, 1992), the reliability ...
This study compared focus attention and interpretation biases in social phobia patients and normal subject. In this study with causal- comparative method 100 subjects with social phobia and 100 normal individuals have compared. Subjects were selected through cluster sampling among Tabriz university students. Data scale of social phobia, attention bias and interpretation of the data was performe...
one of the important factors in making financial decisions is perceptual biases. they influence decisions at the time of exchanging stocks. the present research means to identify these common biases among investors and show its relation with their personality. doing this research, the statistic society is considered unlimited thus a random group of 200 investors from tehran stock exchange has b...
