In this horizon scan article, I review the emerging area of ecological epigenetics in marine animals with studies of DNA methylation as the primary focus. Epigenetic mechanisms such as DNA methylation have the capacity to create rapid changes in phenotypic plasticity. Epigenetic modifications of DNA are mechanisms that modify gene expression, and may do so in marine animals in an environmentall...

OBJECTIVE To characterize the changes in systemic hemodynamics and systolic, diastolic, and global myocardial performance after patent ductus arteriosus (PDA) ligation in very-low-birth-weight infants. STUDY DESIGN Echocardiograms were performed on 23 neonates (mean gestational age, 26.2 +/- 2.2 weeks) at 2.3 +/- 2.0 hours before PDA ligation (n = 23) and at 2.0 +/- 1.4 hours (n = 23) and 23....

Experiments at particle colliders have reached center of mass energies well above 100 GeV, equivalent to temperatures which existed shortly after the big bang. These experiments, testing the initial conditions of the universe have, with great precision, established the Standard Model of Particle Physics. In contrast, the existence of the Higgs boson and perhaps Supersymmetry remain speculative,...

• Clarification of stress intensity factor superposition under crack closure phenomena. Importance geometry changes by for is demonstrated. Proposal and discussion two alternative residual applied definitions. Discussion face contact modelling calculation in fatigue load cycles. The correlation between (SIF) range growth a powerful tool fail-safe design approaches to lightweight structures. key...

This paper provides positive examples of shaping change in African rural communities. First the author discusses perceptions of change and what change really is. Education, extension, and learning are all about change. We need to move beyond simple information, technology transfer, and ‘old-school’ top-down training as means of bringing about change, to real learning opportunities that are empo...

To date, no ontology change management system exists that records the ontology changes based on the different levels of granularity. Once changes are performed using elementary level change operations, they are recorded in the database at the elementary level accordingly. Such a change representation procedure is not sufficient to represent the intuition behind any applied change and thus, cann...
