Dual-mode varifocal Moiré metalens for quantitative phase and edge-enhanced imaging

Nanophotonics
Transport-of-intensity equation (TIE) as a noninterference method for quantitative phase imaging (QPI) has broad applications in micrographic imaging and optical metrology.

Local correlation-based transition model for aerodynamic flows in wide speed range

Engineering Applications of Computational Fluid Mechanics
A local correlation-based transition model is developed for aerodynamic flows in a wide speed range. New localized methods for the momentum-thickness Reynolds number are introduced for constructing local transition indicators. New transition correlations

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

FEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Time-dependent Hamiltonian estimation for Doppler velocimetry of trapped ions

, 2015
The time evolution of a closed quantum system is connected to its Hamiltonian through Schroedinger's equation. The ability to estimate the Hamiltonian is critical to our understanding of quantum systems, and allows optimization of control.

Dihydroorotate dehydrogenase (DHODH) regulates trophoblast syncytialization through organelle stress–induced cellular senescence

FEBS Open Bio, EarlyView.
The inhibition of mitochondrial dihydroorotate dehydrogenase (DHODH) impairs syncytialization and induces cellular senescence via mitochondrial and endoplasmic reticulum stress in human trophoblast stem cells, elevating sFlt1/PlGF levels, a hallmark of placental dysfunction in hypertensive disorders of pregnancy.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

FEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Simulation of the 2010 September 9 Solar Energetic Particle Event by Using a Data-constrained Transport Model

The Astrophysical Journal
Solar energetic particles (SEPs) can cause damage to spacecraft systems and affect human activities in space. On 2010 September 9, a gradual SEP event was observed by spacecraft STEREO-A, Solar and Heliospheric Observatory (SOHO), and STEREO-B at widely ...

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

FEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

MODELING OF ROUGH WALL BOUNDARY LAYERS WITH AN INTERMITTENCY TRANSPORT MODEL

TASK Quarterly, 2010
The paper presents a new extension of the γ-Reθt model to account for both the laminar-turbulent transition and the surface roughness. The new modeling approach takes into account the pressure gradient, turbulence intensity and roughness height and ...
