Uncertainty in non-CO2 greenhouse gas mitigation contributes to ambiguity in global climate policy feasibility

Nature Communications, 2023
Despite its projected crucial role in stringent, future global climate policy, non-CO2 greenhouse gas (NCGG) mitigation remains a large uncertain factor in climate research.

EBV-Positive Sinonasal Plasma Cell Neoplasms: A Case Series With Favorable Outcomes in Elderly Males. [PDF]

EJHaem
ABSTRACT Introduction Epstein–Barr virus positive plasma cell neoplasms in immunocompetent hosts typically behave like aggressive lymphomas, often classified as plasmablastic lymphoma. We evaluated six sinonasal neoplasms in elderly males with unusually indolent courses at Mayo Clinic.

Modeling forest plantations for carbon uptake with the LPJmL dynamic global vegetation model [PDF]

Earth System Dynamics, 2019
We present an extension of the dynamic global vegetation model, Lund–Potsdam–Jena Managed Land (LPJmL), to simulate planted forests intended for carbon (C) sequestration.

Impact of the choice of emission metric on greenhouse gas abatement and costs

Environmental Research Letters, 2015
This paper analyses the effect of different emission metrics and metric values on timing and costs of greenhouse gas mitigation in least-cost emission pathways aimed at a forcing level of 3.5 W m ^−2 in 2100.

Trade-offs between water needs for food, utilities, and the environment—a nexus quantification at different scales

Environmental Research Letters, 2021
With a growing population and a changing climate, competition for water resources in the water-energy-food (WEF) nexus is expected to increase. In this study, competing water demands between food production, freshwater ecosystems and utilities (energy ...

Impact factors for quantifying country-level terrestrial biodiversity intactness footprints (IBIF)

Scientific Data
There is an increasing demand for consistent methods and tools to quantify biodiversity footprints: the magnitude of biodiversity loss associated with all direct and indirect impacts associated with a given human activity or economic actor.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

circZNF148 Drives Glucose Metabolism Reprogramming to Enhance Metastasis and Immune Evasion via HK1 Stabilization in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
CircZNF148 stabilizes HK1 through deubiquitinase recruitment, thereby enhancing glycolysis and lactate production. Elevated lactate promotes PD‑L1 lactylation and membrane accumulation while suppressing CD8+ T‐cell cytotoxicity, collectively facilitating immune evasion and malignant progression in TNBC.
