Coupled motion analysis of tether with time-varying length and rigid bodies

Nihon Kikai Gakkai ronbunshu, 2017
In this paper, we discuss the motion of a tethered system during winding a tether in microgravity. When the tether is being wound, it comes into strong contact with the feeding section of the system.

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

A Coupled Hydrodynamic–Structural Model for Flexible Interconnected Multiple Floating Bodies

Journal of Marine Science and Engineering, 2023
Evaluating the structural safety and seakeeping performance of very large floating structures (VLFS) using the rigid module flexible connector (RMFC) method remains challenging due to the complexity of the coupled hydrodynamic–structural responses in ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Derivation of Equations for Flexible Multibody Systems in Terms of Quasi-Coordinates from the Extended Hamilton’s Principle

Shock and Vibration, 1993
Early derivations of the equations of motion for single rigid bodies, single flexible bodies, and flexible multibody systems in terms of quasi-coordinates have been carried out in two stages.

Fluttering of Flexible Bodies

Sen'i Kikai Gakkaishi (Journal of the Textile Machinery Society of Japan), 1973
In order to clarify the fluttering bahavior of flexible bodies in air streams, the wave form was assumed as y=ax sin (pt+qx), and from the principle of the energy conservation, p and q were determined asp=-0.415V√ (ρ/ρs) (b/l) (Cx+2k0)q=1.6911/lOn the other hand, fabric or film strips were observed in a vertical wind tunnel, and it was shown that the ...
