Below we discuss the partition of the space of real univariate polynomials according to the number of positive and negative roots and signs of the coefficients. We present several series of non-realizable combinations of signs together with the numbers of positive and negative roots. We provide a detailed information about possible non-realizable combinations up to degree 8 as well as a general...

Abstract The toxicity of propachlor (PROP) with its chloroacetanilide members is reported. Rapid and sensitive detection PROP critical for ecotoxicity evaluation the removal process. A novel voltammetric sensor developed based on imprinted poly (o-phenylene diamine-co-pyrrole) (o-PD-co-Py) electrochemically reduced graphene oxide (ERGO) to detect at a trace level. use ERGO provides high density...

Reasoning that overexpression of multiple E2F-responsive genes might be a useful marker for RB1 dysfunction, we compiled a list of E2F-responsive genes from the literature and evaluated their expression in publicly available gene expression microarray data of patients with breast cancer, serous ovarian cancer, and prostate cancer. In breast cancer, a group of tumors was identified, each of whic...
