The Statistic Definition and Research of the One Class Similar Special Curve

This paper use the statistical method to give the similar definition of common broken line. This is the first derivative function of the Linear correlation analysis which is based on the history data of Shenhu Securities Market and through the RSI index line and the closing quotation price line of the financial trading products, which reaching a result of relative analysis coefficient that all bigger than 0.8. This speak volume for that both of the height of the broken line is similar. By using the fitting nature of RSI index line and closing quotation price line, we reach the price predictor formula of financial trading products and make an empirical analysis, which will provide math support for the extreme price of financial trading products by using RS index to judge.

Simulation of mechanoenergetics of asynchronously contracting ventricle

We simulated mechanoenergetics of ventricular asynchronous contraction using a model comprising two compartmentalized asynchronous time-varying elastic elements, E1 and E2. Their elastances [e1(t) and e2(t)] waxed and waned cyclically with a variable time lag (tau). The pressure-volume area (PVA1 or PVA2) circumscribed by the maximum (emax) and minimum e1(t) or e2(t) lines and the contracting pressure-volume trajectory of E1 or E2 quantifies the mechanical energy generated by a contraction of E1 or E2. Similarly, the PVA circumscribed by the resultant Emax (ventricular contractility index) line, the end-diastolic pressure-volume (P-V) line, and the systolic P-V trajectory quantifies the mechanical energy of the entire ventricle. PVA of the ventricle is equal to the sum of PVA1 and PVA2. We found that Emax decreased with increases in tau despite constant emax, and hence ventricular PVA decreased with increases in tau. This simulation helps us to better understand the mechanism of decreased oxygen consumption with increasing ventricular asynchrony reported in the literature.

A Comparison of Grid and Index-Line Trapping Methods for Small Mammal Surveys

An investigation is made of trapping methods used to survey small mammal communities in Australia. Assessment is made of sampling configuration and intensity by comparing combinations of those variables at a field site on Blundells Creek in the Brindabella Range, A.C.T. Indices of diversity were used to analyse capture data. These show that capture data from traps set in a grid configuration are highly sensitive to sampling intensity and are unlikely to represent the true community diversity. In contrast, capture data from traps set along index-lines are relatively immune to sampling intensity differences and closely measure true community diversity.
