Changes in body weight and food choice in those attempting smoking cessation: a cluster randomised controlled trial [PDF]

open access: yes, 2012
<p><b>Background:</b> Fear of weight gain is a barrier to smoking cessation and significant cause of relapse for many people. The provision of nutritional advice as part of a smoking cessation programme may assist some in smoking ...

Comparison of PV and PV/T systems in different regions of China: Energy gain, energy cost, energy payback and energy return

open access: yesEnergy and Built Environment
The photovoltaic/thermal (PV/T) system offers the potential for highly efficient cogeneration and presents significant opportunity for practical applications as compared to pure PV system.

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 ...

Feeding behaviour and its relationship to weight gain in infancy: behaviour and its relationship to weight gain [PDF]

open access: yes, 1997
This thesis involved a longitudinal study of 30 healthy infants from 6 weeks to 15 months to investigate the relationship between feeding behaviour and weight gain in infancy. Poor infant weight gain is associated with adverse outcomes in childhood (e.g.

Probing Proton versus Electron Heating and Energization during Magnetic Reconnection

open access: yesThe Astrophysical Journal
The mechanisms controlling the relative heating and energization of electrons and protons during magnetic reconnection are explored. Simulations are carried out with the kglobal model, which produces bulk heating and the extended power-law distributions ...

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 ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Energy harvesting of nonlinear damping system under time delayed feedback gain

open access: yesMATEC Web of Conferences, 2016
This paper presents the application of delayed feedback velocity for optimizing the harvested power in cubic nonlinear damper system. We consider a harvester consisting of a nonlinear single degree of freedom system (spring-masse-damper) subjected to a ...
