On the Intersection Between AD/HD and DCD: The DAMP Hypothesis [PDF]

open access: yesChild and Adolescent Mental Health, 2003
The paper by Gillberg, ‘ADHD and DAMP’, provides an analysis of the scientific status of the concept of Deficits in Attention Motor Control and Perception (DAMP) in the light of the overlap between Attention Deficit/Hyperactivity Disorder (AD/HD) and Developmental Co‐ordination Disorder (DCD), and the current uncertainty surrounding the significance of

Effect of Heave Plates on the Wave Motion of a Flexible Multicolumn FOWT

open access: yesEnergies, 2022
Three models with different footing types were used to clarify the effect of heave plates on the hydrodynamic behavior of the elastic response of a flexible multicolumn floating offshore wind turbine (FOWT).

Multi-scale modification of aerospace silicone rubber damping material with wide temperature range

open access: yesCailiao gongcheng, 2021
Silicone rubber has stable performance in a wide temperature range. However, as its damping factor in the effective damping temperature range is small and the damping performance is limited, multi-scale modification is required.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

PANoptosis in the pathogenesis of myelodysplastic syndromes

open access: yesMolecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Numerical analysis of fluid-added parameters for the torsional vibration of a Kaplan turbine model runner

open access: yesAdvances in Mechanical Engineering, 2017
The impact of fluid on the runner of a hydraulic turbine is a recurrent problem. Fully coupled fluid–structure simulations are extremely time-consuming.

Added mass and damping of structures with periodic angular shape

open access: yesJournal of Fluid Mechanics, 2022
Symmetry relations are derived for the added mass and damping of structures where the shape is unchanged by rotation about the vertical axis through an angle $\theta = 2 {\rm \pi}/N$ with the integer $N\ge 3$ .
