[Automatic Measurement of the Stellar Atmospheric Parameters Based Mass Estimation].

We have collected massive stellar spectral data in recent years, which leads to the research on the automatic measurement of stellar atmospheric physical parameters (effective temperature Teff, surface gravity log g and metallic abundance [Fe/ H]) become an important issue. To study the automatic measurement of these three parameters has important significance for some scientific problems, such as the evolution of the universe and so on. But the research of this problem is not very widely, some of the current methods are not able to estimate the values of the stellar atmospheric physical parameters completely and accurately.

[Spectra Classification Based on Local Mean-Based K-Nearest Centroid Neighbor Method].

In the present paper, a local mean-based K-nearest centroid neighbor (LMKNCN) technique is used for the classification of stars, galaxies and quasars (QSOS). The main idea of LMKNCN is that it depends on the principle of the nearest centroid neighborhood(NCN), and selects K centroid neighbors of each class as training samples and then classifies a query pattern into the class with the distance of the local centroid mean vector to the samples . In this paper, KNN, KNCN and LMKNCN were experimentally compared with these three different kinds of spectra data which are from the United States SDSS-DR8.

[SKLOF: a new algorithm to reduce the range of supernova candidates].

Supernova (SN) is called the "standard candles" in the cosmology, the probability of outbreak in the galaxy is very low and is a kind of special, rare astronomical objects. Only in a large number of galaxies, we have a chance to find the supernova. The supernova which is in the midst of explosion will illuminate the entire galaxy, so the spectra of galaxies we obtained have obvious features of supernova.

[Effect of resuscitation strategy based on the early goal directed therapy on the prognosis of patients with shock].

Objective: To evaluate the effects of fluid management strategies in early goal directed therapy (EGDT) on the prognosis of patients with shock.

Methods: Clinical data of 79 patients with septic shock or hemorrhagic shock admitted to emergency intensive care unit (EICU) of the First People's Hospital of Yunnan Province were retrospectively analyzed. Patients were divided into continual fluid administrating group (n=41) in accordance with protocol calculating approximating fluid volume and adjust the infusion speed based on blood pressure, heart rate, pulse saturation of blood oxygen (SpO(2)) and urine output with the end of fluid resuscitation was set to restore spontaneous circulation function and wean off vasoactive drugs, and the conservative fluid resuscitation group (n=38) by means of using vasoactive agents to maintenance blood pressure after infusing amount (20 ml/kg) of liquid early, respectively.
