low stacking fault energy face centered cubic (fcc) materials contain characteristic defect structures. stackingfault tetrahedral are one of those rare structures that occur under special experimental conditions. for the first time,stacking fault tetrahedral were observed in fe-30mn-3al-3si twinning induced plasticity (twip) steel. theirpresence resulted from a quenching heat treatment.

onprior evidence thatobservation isused infrequently inmen with low-risk disease,5 this study establishes that active surveillance use is low. Usage increases as the inclusion criteria for surveillance becomemore stringent, ie, less likely tomiss significant disease. While active surveillance is aptly applied to elderly men, its use is sporadic, confined to academic and regional hospitals, and ...

Consider, in the study of the evolution of human beings, consciousness, and intelligence, the hypothesis that men are a special instance of the reflection of nature, and later in return to this notion, as unproven hypothesis, consider the dynamics of a town meeting when asking about intelligence, consciousness, the genes or evolution, when questioning to scientific rigor, the origin and nature ...

Hypothesis-driven experimentation - the scientific method - can be subverted by fraud, irreproducibility, and lack of rigorous predictive tests. A robust solution to these problems may be the 'massive open laboratory' model, recently embodied in the internet-scale videogame EteRNA. Deploying similar platforms throughout biology could enforce the scientific method more broadly.

This paper brings together some modern statistical methods to address the problem of missing data in obesity trials with repeated measurements. Such missing data occur when subjects miss one or more follow-up visits, or drop out early from an obesity trial. A common approach to dealing with missing data because of dropout is 'last observation carried forward' (LOCF). This method, although intui...

this is a descriptive study. the purpose was to determine how children with leukemia receives nursing care. a sample of 40 children with leukemia from six hematology wards in three hospitals was selected. data were gathered by observation, children's documents, and then filling an observational check list. results showed that nursing care in 65 percent of cases was intermediate, and in 35 ...

Abstract Using data taken at 29 center-of-mass energies between 4.16 and 4.70 GeV with the BESIII detector Beijing Electron Positron Collider corresponding to a total integrated luminosity of approximately 18.8 , process e^+e^- \to p \bar{p} \bar{n} \pi^{-} + c.c. is observed for first time statistical significance 11.5\sigma . The average Born cross sections in energy...
