The Effects of Ice Floe‐Floe Interactions on Pressure Ridging in Sea Ice

open access: yesJournal of Advances in Modeling Earth Systems, 2021
The mechanical interactions between ice floes in the polar sea‐ice packs play an important role in the state and predictability of the sea‐ice cover. We use a Lagrangian‐based numerical model to investigate such floe‐floe interactions.

Rafts to the front; rafts to the rear [PDF]

open access: yesThe Journal of Cell Biology, 2001
![Graphic][1] GM3 (red) and GM1 (green) at the opposite ends of a T cell. Manes/NAS Tcells assemble different rafts at the front and rear of the cell as they gear up to move.

Microstructural Changes of a Creep-Damaged Nickel-Based K002 Superalloy Containing Hf Element under Different HIP Temperatures

open access: yesHigh Temperature Materials and Processes, 2016
Effects of hot isostatic pressing (HIP) temperature on the microstructural evolution of a nickel-based K002 superalloy containing Hf element after long-term service were investigated using three different soaking temperatures during HIP.

Review of γ’ Rafting Behavior in Nickel-Based Superalloys: Crystal Plasticity and Phase-Field Simulation

open access: yesCrystals, 2020
Rafting is an important phenomenon of the microstructure evolution in nickel-based single crystal superalloys at elevated temperature. Understanding the rafting mechanism and its effect on the microstructure evolution is of great importance in ...

Metabolic scaling of fire ants (Solenopsis invicta) engaged in collective behaviors

open access: yesBiology Open, 2022
During flash floods, fire ants (Solenopsis invicta Buren) link their bodies together to build rafts to stay afloat, and towers to anchor onto floating vegetation.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

open access: yesFEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...
