Extracranial-intracranial bypass surgery was performed prior to carotid resection in eight patients with head and neck carcinoma that involved the carotid artery near the skull base. Four patients underwent the standard one-stage extracranial-intracranial bypass procedure. A two-stage procedure was performed in the remaining four patients. The procedure first involved an anastomosis between the...

We propose a two-stage procedure for estimating the location μ and size M of the maximum of a smooth d-variate regression function f(x). Our procedure is motivated by Tang, Banerjee and Michailidis (2011). In the first stage, a preliminary estimator of μ obtained from a standard nonparametric smoothing method is used. At the second stage, we “zoom-in” near the vicinity of the preliminary estima...

knowledge of energyconsumption has many uses in industry. factors that are energy dependent have already been studied hence decision making on them are easier. energy demand studies of industry helps us to learn factors that are responsive to this demand. therefore planners can use these collected data in their decision making using the above factors. another use of energy demand can be used as...

This paper uses simulation to explore the performance of a two-stage procedure where a preliminary Shapiro-Wilk test is used to choose between the ANOVA and Kruskal-Wallis tests as a three-sample location test. The results suggest that the two-stage procedure actually seems to be preferable when conducting such location tests.

We herein introduce a new method of interpretable clustering that uses unsupervised binary trees. It is a three-stage procedure, the first stage of which entails a series of recursive binary splits to reduce the heterogeneity of the data within the new subsamples. During the second stage (pruning), consideration is given to whether adjacent nodes can be aggregated. Finally, during the third sta...

The increasing number of experimenters using computer-generated experimental designs creates an increasing need to have design procedures that are less sensitive to model misspecification. To address this problem, the notion of empirical models that have both important and potential terms is used. A two-stage design strategy for planning experiments in the face of model uncertainty is proposed....

breast cancer (bc) accounts for one of the major health problems around the world. since the diagnosis process can have great effect on therapy outcomes, we studied the biomarkers specific to breast tumors stage i based on examining different iranian patients. cases from different stages were examined to discover their highly expressed proteins. in addition, pathologic evaluations were performe...

introduction: mouse embryos can successfully be frozen with sucrose and propandiol. however, different developmental stages of mammalian embryos have shown to have various capacities to undergo freeze-thawing procedure. in the present study, the ability of 1,2,4 and 8-ell mouse embryo to tolerate the freeze-thawing procedure was investigated and the effect of this procedure on the further in vi...
