Re-imagining delightful experiences in “New Normal” conditions: A systematic critical review and future research agenda

Disasters and crises, including the COVID-19 pandemic, have created an uncertain and challenging environment, particularly for the hospitality and service-based industries, forcing managers to seek effective approaches in designing and staging delightful

Critical conditions for phytoplankton blooms [PDF]

, 2001
We motivate and analyze a reaction-advection-diffusion model for the dynamics of a phytoplankton species. The reproductive rate of the phytoplankton is determined by the local light intensity.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Changes in environmental conditions are critical factors for optimum biomass, lipid pattern and biodiesel production in algal biomass

, 2022
Microalgae and their metabolites can be influenced by their environment, effects that can be investigated in a laboratory by modifying the composition of the cultivation medium.

A flume experiment on critical flow conditions with gravel dunes

Shui kexue jinzhan, 2013
Gravel dunes are the typical form of bed load motion and one of the research focuses in river dynamics,which determines the bed resistance,the bed geometry and the bed load transport rate in alluvial rivers.Most previous studies focused on the fine ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Critical Junctures and Conditions of Change: Exploring the Fall of Prison Populations in US States

, 2018
State prison populations in the United States have been regularly declining since 2009, and, at the end of 2014, the combined federal and state prison population was at its lowest level since 2005.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
