This paper compares state-equation models to state-machine models. It compares continuous system models to discrete system models. The examples were designed to be at the same level of abstraction. This paper models these systems with the following methods: the state-space approach of Linear Systems Theory, set-theoretic notation, block diagrams, use cases, UML diagrams and SysML diagrams. This...

Endoglin (ENG) is a causative gene of type 1 hereditary hemorrhagic telangiectasia (HHT1). HHT1 patients have a higher prevalence of brain arteriovenous malformation (AVM) than the general population and patients with other HHT subtypes. The pathogenesis of brain AVM in HHT1 patients is currently unknown and no specific medical therapy is available to treat patients. Proper animal models are cr...

Background Different methods have been proposed to estimate Wall Shear Stress (WSS). Morgan and co-workers (J Thorac Cardiovasc Surg and Ann Biomed Eng 1998) used a finite difference scheme to quantify the WSS tensor. However, it is well known that finite-difference methods cannot effectively handle complex geometries, as those found in the cardiovascular system. To account for arbitrary cross-...

Novel flocculants have been synthesized on the basis of glycogen. The efficiency of cationic glycogen can be explained in terms of Singh’s qualitative easy approachability model (EAM). The jar test was used previously to evaluate flocculation efficacy, but we have recently shown that a plot of interface height vs. settling times provides a better measure. In accord with the EAM, a one-to-one co...

Pre-eclampsia is a devastating disease of late (after week 20) pregnancy. The condition features hypertension, proteinuria, premature labor, haemolysis, liver abnormalities, thrombocytopenia (HELLP syndrome), seizures (eclampsia) and death [1]. Both mothers and children, if they survive delivery, can expect subsequent increased cardiovascular risk in the future. Preeclampsia affects about 5% of...

Exochus atlanticus sp. n., Melo & Penteado-Dias, and Trieces broadi sp. n., Melo & Penteado-Dias, are described and illustrated in Brazilian fauna. The genus Exochus and the species E. ablatus, E. izbus, T. azipas, T. riodinis, T. wardae, T. upermia and T. wascia, are recorded for the first time from Brazil. Diagnosis and distribution information for each species are provided.
