Computed tomography (CT) uses thousands of x-ray transmission measurements taken at different angles around a patient to produce three-dimensional cross-sectional images the human body. That technology allows physicians visualize their patients’ internal anatomy, as shown in opening image, and reveals presence acute chronic diseases consequences injury remarkable detail. Prior integration CT in...

Abstract Being 100 years since the birth of macromolecular science, 2020 was meant to be “Year Polymers,” but instead it turned into year pandemic. Actually two are not unrelated —most PPE is made polymer, and without health-care response COVID-19 would have looked completely different been far more treacherous. But that’s another story, one with which IUPAC Polymer Division engaging [1]. Here ...

Complex simian virus 40 DNA produced by a soluble cell-free extract derived from stage 6 oocytes of Xenopus laevis consists of fully relaxed circles (i.e., with no superhelical turns). An endonuclease and a DNA-relaxing protein, either or both of which could be responsible for the relaxation of the complex DNA, have been purified from the extract. The endonuclease(s) produces nicked circles (ha...

Abstract In this paper, we investigate the central limit theorem and invariance principle for linear processes generated by a new notion of independently identically distributed (IID) random variables sub-linear expectations initiated Peng [19]. It turns out that these theorems are natural fairly neat extensions classical Kolmogorov’s to case where probability measures no longer additive.
