Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Investment in Tourism Market: A Dynamic Model of Differentiated Oligopoly [PDF]

open access: yes
We present a theoretical model in tourism economics, assuming that the market for tourism is an oligopoly with differentiated products. Destinations (i.e., countries, regions, sites or even firms) can invest in order to improve their carrying capacity ...

A regulatory transcriptional loop controls proliferation and differentiation in Drosophila neural stem cells [PDF]

open access: yes, 2014
Neurogenesis is initiated by a set of basic Helix-Loop-Helix (bHLH) transcription factors that specify neural progenitors and allow them to generate neurons in multiple rounds of asymmetric cell division.

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

open access: yesFEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

Hardware-in-the-loop Multi-satellite Simulator for Proximity Operations

open access: yes, 2010
This paper addresses the first steps realized to set up a hardware in-the-loop (HWIL) multi-satellite simulator aimed at the support of closed-loop real-time real-scale On-Orbit Servicing (OOS) scenarios.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Dynamic pricing model for the operation of closed-loop supply chain system

open access: yes, 2011
A class of closed-loop supply chain system consisting of one manufacturer and one supplier is designed, in which re-distribution, remanufacturing and reuse are considered synthetically.

From state-of-the-art ventilation to closed loop ventilation

open access: yes, 2022
Recent emphasis on energy load delivered during each ventilatory breath has opened a new insight to reduce harmful ventilatory induced lung injury, but no robust clinical evidence of patient benefit produced yet. Closed loop ventilation is a strategy to

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 ...

NONRENEWABLE RESOURCE OLIGOPOLIES AND THE CARTEL-FRINGE GAME [PDF]

open access: yes
We specify and solve a closed-loop dominant firm nonrenewable resource game, with a price-taking fringe. We show that (i) the outcomes of the closed-loop and the open-loop dominant firm nonrenewable resource game (a la Salant 1976) coincide and (ii) when
