A brief historical perspective is first given concerning financial crashes, from the 17th till the 20th century. In modern times, it seems that log periodic oscillations are found before crashes in several financial indices. The same is found in sand pile avalanches on Sierpinski gaskets. A discussion pertains to the after shock period with illustrations from the DAX index. The factual financia...

A slow outward current associated with spike frequency adaptation has been studied in the giant Aplysia neurons R2 and LP1. The current was observed during 60-s voltage clamp commands to potentials just below spike threshold. The slow outward current shows a marked voltage dependence at membrane potential less negative than -40 mV. The slow outward current is associated with increased membrane ...

Introduction: Micro-perforated absorbents are one of the structures that are widely used nowadays. The sound absorption mechanism is performed by viscous energy losses in the cavities on the plate. In this study, the acoustic properties of non-flat perforated panels in oblique angle was investigated in numerical method. Material and Methods: This paper examined the effect of the surface shape ...

the upaniṣads, as one of the trilogy of principal vedāntic texts, the oldest and the most fundamental of them, have exposed a more or less detailed discussion on dreaming, taking it whether as the factual object of their discourse or as a symbol. however, there has been a debate between different schools of vedāntic philosophy about oneirology, science of dreams and their interpretation, discus...

Thiazinones containing sulfonamides are experiencing increased interest due to their importance in the design and development of new molecules potential pharmaceutical interest. The synthesis a series Nsubstituted 2H-1,3-thiazin-2-ones sulfonamide is described. compounds were synthesized good yields one-pot reaction starting from commercially available chlorosulfonyl isocyanate (CSI), 3chloro-1...

We investigate the automatic detection of sentences containing linguistic hedges using corpus statistics and syntactic patterns. We take Wikipedia as an already annotated corpus using its tagged weasel words which mark sentences and phrases as non-factual. We evaluate the quality of Wikipedia as training data for hedge detection, as well as shallow linguistic features.

Floating point addition/subtraction has been designed in literature. The methods involved two’s complements add/subtract logic and XOR for counting leading zeroes. This paper proposes algorithm to perform add/subtract operation using one’s complement and counting leading zeroes for normalization using NOR operation as reduction operator for two bits of mantissa at a time. The proposed model is ...
