Rapid loss of Arctic sea ice [PDF]

arXiv, 2022
Several environmental tipping points and self-reinforcing feedback loops are still disregarded within the frequently used climate models. Thus, existing climate models are not very representative for providing projections of the conditions after the actual environmental tipping points are triggered.

A PANoptosis‐Based Signature for Survival and Immune Predication in Glioblastoma Multiforme

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PANoptosis is a concept of total cell death characterized by pyroptosis, apoptosis, and necroptosis. We aimed to explore the clinical significance of PANoptosis‐related genes (PARGs) in glioblastoma multiforme (GBM). Methods Expression profiles of GBM were downloaded from the XENA database as a training dataset to construct a ...

Climate Change, Regionalism, and Universalism: Elegy for the Arctic and the Antarctic? [PDF]

, 2020
The Arctic lays north of the Arctic Circle, at a minimum latitude of 66.33°, that is, the most northerly of the major circles of the Earth’s latitude. The Arctic Circle is essentially an ocean surrounded by land; it includes portions of the territories ...

Exploiting Geometric Frustration in Coupled von Mises Trusses to Program Multifunctional Mechanical Metamaterials

Advanced Engineering Materials, EarlyView.
Mechanical metamaterials capable of compressive stiffness tunability, shape morphing, and post‐fabrication modularity. Herein, the 3D unit cell design is based on an assembly of bistable von Mises trusses that exhibit a switch in compressive stiffness and resting height from one stable state to the other.

Arctic sea ice melt leads to atmospheric new particle formation

Scientific Reports, 2017
Atmospheric new particle formation (NPF) and growth significantly influences climate by supplying new seeds for cloud condensation and brightness. Currently, there is a lack of understanding of whether and how marine biota emissions affect aerosol-cloud ...

Key winter habitat of the ivory gull Pagophila eburnea in the Canadian Arctic

Endangered Species Research, 2016
The ivory gull Pagophila eburnea is a rare Arctic seabird that breeds in remote locations; little is known of its winter distribution and behaviour. It is listed under Canadian legislation as ëendangeredí, and as ënear threatenedí by the International ...

Arctic Sea Ice State Estimation From Thermodynamic PDE Model [PDF]

arXiv, 2019
Recent rapid loss of the Arctic sea ice motivates the study of the Arctic sea ice thickness. Global climate model that describes the ice's thickness evolution requires an accurate spatial temperature profile of the Arctic sea ice. However, measuring the complete temperature profile is not feasible within and throughout the Arctic icecap.
