Due to the high mortality in this cohort and high number of patients dying within 7 days of clinical deterioration, we additionally performed all analyses including a composite outcome of ARDS or death as well as a competing risk analysis where early mortality was modeled as the competing risk for ARDS. After accounting for the r...

This is the second paper on the study of gradient recovery for elliptic interface problem. In our previous work [H. Guo and X. Yang, 2016, arXiv:1607.05898], we developed a novel gradient recovery technique for finite element method based on body-fitted mesh. In this paper, we propose new gradient recovery methods for two immersed interface finite element methods: symmetric and consistent immer...

The aim of this paper is to present some early findings of the pilot implementation of Learning Design at the Hellenic Open University (HOU). This study represents the first step of a broader effort that seeks to use learning design tools to support tutors and learners in distance education across our university by charting existing international experience and methodology. This study aims to i...

Analysis and extraction of strongly frequency modulated signals have been a challenging problem for adaptive data analysis methods, e.g., empirical mode decomposition [N.E. Huang et al., R. Soc. Lond. Proc. Ser. A Math. Phys. Eng. Sci., 454 (1998), pp. 903–995]. In fact, many of the Newtonian dynamical systems, including conservative mechanical systems, are sources of signals with low to strong...

Xiang-dong Hou has stepped down as Graduate Program Director after five years. He is succeeded by Brian Curtin. We thank Professor Hou for his service. Lu Lu has been reassigned as a tenure-track assistant professor. She received her Ph.D. in statistics from Iowa State in 2009, and a post doc at Los Alamos, USF hired her as a visiting assistant professor in 2013. Dima Savchuk was awarded tenure...

All undergraduate and postgraduate students of the Hellenic Open University (HOU) attend courses at a distance. The lack of a live academic community is reported by many as a drawback in their studies. Systematic exploitation of new communication and collaboration technologies is desirable in HOU but cannot be imposed universally as the average student’s IT competence level is relatively low. I...

Inspired by the numerical evidence of a potential 3D Euler singularity [54, 55], we prove finite time from smooth initial data for HL model introduced Hou-Luo in 55] equations with boundary. Our blowup solution and singular considered share some essential features, including similar exponents, symmetry properties solution, sign solution. We use dynamical rescaling formulation strategy proposed ...

In a recent paper, Hou and Hsu (1991) derive a state-space identii-cation method which apparently improves upon the results in (Moonen et al. 1989). Here we point out that neither one of these methods really applies to the examples given in the paper, and we give an outline of a method which should be used instead. In their paper, Hou and Hsu (1991) consider general state space models of the fo...
