Partitioned simulation strategies for fluid–structure–control interaction problems by Gauss–Seidel formulations

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2018
In this contribution the multi-physics problem of fluid–structure–control interaction (FSCI) is solved by an iterative, partitioned approach utilizing Gauss–Seidel formulations.

Analysis of structured programs

open access: yesJournal of Computer and System Sciences, 1973
We compare the structural complexity of various classes of structured programs. To achieve this we concentrate on a notion called “reducibility”. Loosely speaking, given two classes of programs C1 and C2, we say that C1 is reducible to C2 (C1≤wC2) if and only if for every program P in C1, there is a program in C2 that computes the same function as P ...

Structural Analysis of Tn5

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 1981
Nucleotide sequences have been determined for the 1.5-kb inverted repeats of Tn5 and for their junctions with the central unique region and with host DNA. The primary findings stemming from this analysis are: 1. Integration of Tn5 is accompanied by the duplication of 9 bp of host DNA. 2.

Magnetic hydrogel with long in situ retention time for self-regulating temperature hyperthermia

open access: yesInternational Journal of Hyperthermia, 2021
Aim: Magnetic hydrogels (MHGs) have been proposed to avoid the redistribution and loss of magnetic nanoparticles (MNPs) when administrated by intratumoral injection.

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Fabrication and mechanical properties of self-toughening ZrB2–SiC composites from in-situ reaction

open access: yesJournal of Advanced Ceramics, 2019
Self-toughening ZrB2–SiC based composites are fabricated by in-situ reactive hot pressing. The effect of sintering additive content on the microstructure and mechanical properties of the composites is investigated.
