handwritten digit recognition can be categorized as a classification problem. probabilistic neural network (pnn) is one of the most effective and useful classifiers, which works based on bayesian rule. in this paper, in order to recognize persian (farsi) handwritten digit recognition, a combination of intelligent clustering method and pnn has been utilized. hoda database, which includes 80000 p...

We observed an anomalously outbursting state of SU UMa which occurred in 1992. Time-resolved photometry revealed the presence of signals with a period of 0.0832±0.0019 d, which is 3.6σ longer than the orbital period (0.07635 d) of this system. We attributed this signal to superhumps, based on its deviation from the orbital period and its characteristic profile. During this anomalous state of SU...

Utilizing a rich export restriction database that covers 527 agricultural products at the six-digit Harmonized System (HS) code level in 168 countries from 2005 to 2015, this article investigates political and economic determinants of countries’ decisions. Empirical analysis shows one standard deviation increase commodity's market power increases probability an on commodity by 5.5%, country's n...

This paper analyses China’s ICT exports growth in its two major markets Japan and the US from 1992 to 2004. It focuses on ICT products classified in SITC 75, 76 and 77. The empirical results show that Chinese exports had maintained two-digit annual growth during the period. The growth was much higher than the corresponding growth of the overall markets. By 2004, Chinese ICT exports accounted fo...

Domestic innovations and technology imports play important roles in boosting relative demand for skilled labor force. These factors are in turn influenced by domestic R&D investments and international trade. Using a translog cost function, this paper studies the effect of technology imports and other factors including output level and physical capital stock on the shares of skilled labor force ...

Context. The hot subdwarf B star HS 0702+6043 is known as a large-amplitude, short-period p-mode pulsator of the EC 14026 type. Its atmospheric parameters place it at the common boundary between the empirical instability regions of the EC 14026 variables and the typically cooler long-period g-mode pulsators of the PG 1716 kind. Aims. We analyse and interpret the photometric variability of HS 07...

We explore the use of certain image features, blockwise histograms of local orientations, used in many current object recognition algorithms, for the task of handwritten digit recognition. Existing approaches find that polynomial kernel SVMs trained on raw pixels achieve state of the art performance. However such kernel SVM approaches are impractical as they have a huge complexity at runtime. W...

Unloading skeletal muscle results in atrophy and weakness. Inhibition of calpain activity during unloading reduced atrophy, but the impact on force generation has not been determined. Our hypothesis was that inhibition of calpain, through muscle-specific overexpression of calpastatin, would prevent the disruption of sarcomere structure and decreased specific force (kN/m(2)) observed during unlo...
