Aggressive Glioblastoma Cells Enhance the Migratory Persistence and Velocity of Less Aggressive Cells to Promote Tumor Dissemination

open access: yesSmall, EarlyView.
We identify biophysical motility parameters explaining how less aggressive EGFRwt‐overexpressing Glioblastoma cells become more infiltrative when influenced by aggressive EGFRvIII‐expressing cells. Using bulk assays and microfluidic chips, we show that EGFRvIII cells enhance velocity and persistence in EGFRwt cells via Src‐mediated communication ...

From Native-like Selections to English Academic Performance: Exploring the Knowledge Base of English Bilinguals [PDF]

open access: yesIranian Journal of Language Teaching Research, 2017
Pawley and Syder (1983) pointed out that idiomatic expressions can be discussed in terms of nativelike selection (NLS), which refers to the ability of the native speaker to express his/her intended meaning using an expression that is not only grammatical

Volumetric Single‐Molecule Tracking Inside Subcellular Structures

open access: yesSmall, EarlyView.
This correlative microscopy approach integrates single‐molecule light‐field microscopy (SMLFM) with widefield Fourier light‐field microscopy (FLFM) to enable 3D single‐molecule tracking within the organelles of living mammalian cells. Instantaneous volumetric segmentation enhances the sensitivity of molecular organization and diffusion measurements ...

Application of multigrid NLS-4DVar in radar radial velocity data assimilation with WRF-ARW

open access: yesAtmospheric and Oceanic Science Letters, 2019
The nonlinear least-squares four-dimensional variational assimilation (NLS-4DVar) method introduced here combines the merits of the ensemble Kalman filter and 4DVar assimilation methods.

Fast Switching and High Polarization in Ferroelectric Hf0.5Zr0.5O2 Films

open access: yesSmall Science, EarlyView.
Ferroelectric Hf0.5Zr0.5O2 thin films are grown under tuned redox conditions to simultaneously achieve high polarization and fast switching. Control of defect dipoles and internal fields enables stable domain wall motion without compromising performance. This work provides a pathway for designing fast and energy‐efficient ferroelectric devices.

Gradual pollen release in a buzz‐pollinated plant: Investigating pollen presentation theory under bee visitation

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,

Gendered processes of recruitment to elite higher educational institutions in mid‐twentieth century Britain

open access: yesGender &History, EarlyView.
Abstract This article uses rare and detailed data on matriculants to the University of Oxford during the middle decades of the twentieth century as a prism through which to consider gendered processes of recruitment to elite institutions. The article makes four key claims. First, the broader shifts in middle‐class women's labour market participation in

Nanolipsome Modified with Inulin and Pea Protein Isolate Improve the Thermal Stability and Slow the Release of Anthocyanin at Simulated In Vitro Digestion and Hot Cocoa Beverage

open access: yesFoods
Anthocyanin (ACN) is a natural pigment with various biological activities, but their stability is compromised by external environmental factors, which limits their practical application in food processing.
