The effects of cumulative vs noncumulative afterhyperpolarization (AHP) are examined through simulations of a stochastic neural model (Smith and Goldberg, 1986). The afterhyperpolarization in the model is due to a timevarying potassium conductance. Cumulative effects result from summing the residual activity of the potassium conductance in the preceding interspike interval. The variablity in th...

McClelland believed that Competence Model can be divided into two parts: water ice and underwater part of the iceberg. Water ice, that is Threshold Competence, which is based on the quality requirements for competent persons, but it can not with the good performers who distinguish between mediocre. Underwater part of the iceberg of social roles, self-concept, character and motivation of compete...

Pyramidal neurons in the piriform cortex from olfactory-discrimination trained rats show enhanced intrinsic neuronal excitability that lasts for several days after learning. Such enhanced intrinsic excitability is mediated by long-term reduction in the post-burst after-hyperpolarization (AHP) which is generated by repetitive spike firing. AHP reduction is due to decreased conductance of a calci...

Activation of group I metabotropic glutamate receptors (mGluRs) leads to a concerted modulation of spike afterpotentials in guinea pig hippocampal neurons including a suppression of both medium and slow afterhyperpolarizations (AHPs). Suppression of AHPs may be long-lasting, in that it persists after washout of the agonist. Here, we show that persistent AHP suppression differs from short-term, ...

OBJECTIVES To determine the most common ocular causes and types of abnormal head position (AHP) and describe their clinical features. MATERIALS AND METHODS Patients with AHP who had been followed in the strabismus unit were retrospectively reviewed. Demographic features and orthoptic characteristics were recorded. RESULTS A total of 163 patients including 61 women (37.4%) and 102 men (62.6%...

Employment is a problem faced by every fresh graduate. Graduates from different majors choose the right job according to their own situations. However, typically graduates would find it difficult to make judgments of jobs, thus missing out their most appropriate chances. In this paper, the AHP model is introduced to state the problems encountered by graduates and the relevant factors that affec...

This study project is related to resource allocation of contract funds for the U.S.DOT/Federal Transit Administration (FTA) Capital Project Management Oversight (CPMO) Program. Contract proposals exceed the budget cap that FTA is allowed to obligate for oversight consultants in 15 regions in the U.S. An Analytical Hierarchy Process (AHP) was used for developing a resource allocation methodology...

Development of sustainable manufacturing system is a key research area to realise the Sustainable Development Goal of any country. In this research work we have developed a model for development of a sustainable manufacturing process using fuzzy-AHP. The fuzzy-AHP technique is used to determine the effect of various factors affecting the sustainability of a product. The study shows that, adopti...

Mobile phones have become indispensable in our everyday life. The fierce market competition characterized by rapid expansion of advanced functionality and feature is making consumers’ mobile phone selections increasingly complex and challenging. In this study, we use Analytic Hierarchy Process (AHP), a multiple criteria decision method, to build a recommendation system for mobile phones selecti...

Enterprises are constituted by a number of employees, Employee Satisfaction directly determine their level of enthusiasm, which affecting the basic conditions of human resources. In this area, the research about retail industries is weak. In view of this paper is to make my own explorations. So I explore the characteristics and features of investigation upon the research of Employee Satisfactio...
