Inferring North American Holocene Land Cover Change using Paleoecological Evidence
Climate-vegetation feedbacks (CVFs) can amplify or mitigate climate variations. These feedbacks operate at multiple timescales. Fast processes such as leaf-scale carbon fluxes operate at sub-annual timescales, while slow processes, driven by changes in forest composition and structure, occur over decadal and longer timescales. Slow processes are rarely directly observed from instrumental data; yet

Holocene Land Cover Change in North America: Trends, Drivers, and Feedbacks
Land cover governs biogeophysical and biogeochemical feedbacks between the land surface and atmosphere. Holocene vegetation-atmosphere interactions are of particular interest, both to understand the climate effects of intensifying human land use and as a possible explanation for the Holocene Conundrum, a widely studied mismatch between simulated and reconstructed temperatures. Progress addressing
Deep Learning for Resolving 3D Microstructural Changes in the Fibrotic Liver
Portal hypertension, a life-threatening complication of cirrhosis,is largely triggered by increased intrahepatic vascular resistance.Fibrosis, regenerative nodule formation, intrahepatic angiogenisis and sinusoidalremodelling are classical mechanisms that account for increasedintrahepatic vascular resistance in cirrhosis. Our study leverages highresolution3D synchrotron radiation-based microtomogr
Conceptual design of a 3rd harmonic cavity system for the LNLS electron storage ring
The installation of a second RF cavity in the UVX electron storage ring at the Brazilian Synchrotron Light Laboratory (LNLS) at the end of 2003 brought about longitudinal instabilities driven by one of the HOMs of the new cavity. Even though the operational difficulties related to these unstable modes were successfully overcome by means of a combination of cavity tuning (using temperature and plun
Advances in beam orbit stability at the LNLS electron storage ring
We describe recent efforts made at the Brazilian Synchrotron Light Source (LNLS) to improve beam orbit stability. The main driving force is the high positional stability required by some specific experiments and particularly by a high resolution undulator beamline which is being built at LNLS. Recent steps taken to improve orbit stability include the development of x-ray BPMs to measure the vertic

Holocene land cover change in North America: continental trends, regional drivers, and implications for vegetation-atmosphere feedbacks
Land cover governs the biogeophysical and biogeochemical feedbacks between the land surface and atmosphere. Holocene vegetation-atmosphere interactions are of particular interest, both to understand the climate effects of intensifying human land use and as a possible explanation for the Holocene Conundrum, a widely studied mismatch between simulated and reconstructed temperatures.

Who Is Responsible? Social Identity, Robot Errors and Blame Attribution
This paper argues that conventional blame practices fall short of capturing the complexity of moral experiences, neglecting power dynamics and discriminatory social practices. It is evident that robots, embodying roles linked to specific social groups, pose a risk of reinforcing stereotypes of how these groups behave or should behave, so they set a normative and descriptive standard. In addition,
Developing a guide for sustainable healthcare practice : A case study from the Swedish Society of Medicine
Introduction: Although climate change has been consistently identified as one of the greatest threats to humans, many clinicians do not feel prepared to address climate change with patients and medical school curricula still have very little coverage of its health consequences. At the same time, health care providers have been shown to be trusted voices and are therefore well suited to help build
Assessing the Effect of Specimen Preparation Methods on DSR Test Results of Bitumen Using Factorial Design Analysis
A two-level three-factor factorial design experiment was conducted to study the influences of three critical specimen preparation parameters on the measurement results of bitumen by a dynamic shear rheometer (DSR). The investigated factors were (1) the pre-heating temperature (HT) for manufacturing the specimen, (2) the bonding temperature (BT) onto the rheometer, and (3) the trimming (Trim) opera
Single-Source Localization as an Eigenvalue Problem
This paper introduces a novel method for solving the single-source localization problem, specifically addressing the case of trilateration. We formulate the problem as a weighted least-squares problem in the squared distances and demonstrate how suitable weights are chosen to accommodate different noise distributions. By transforming this formulation into an eigenvalue problem, we leverage existin
Synthetic strategies towards ether-free polymeric hydroxide conducting membranes
The only way to combat the depletion of resources and climate crisis is to reduceour dependence on fossil fuels. Renewable sources, such as wind and solar energy,are increasingly used to meet our ever-growing energy demands; however, they areintermittent. One promising solution to the power crisis in the world is fuel cells,which, unlike the combustion engine, can operate on renewable fuels such a

External evaluation of the scientific basis of the assessment system for ecological condition in Norway
This report is an external evaluation of the scientific basis of the Norwegian assessment system for ecological condition (Fagsystem for økologisk tilstand), commissioned by the Ministry of Climate and Environment (KLD).

Dynamic Shear Rheometer for rheological investigation of bitumen in road applications : The impact of measurement technique
The rheological properties of bituminous binders tested with a dynamic shear rheometer (DSR) as a function of loading time and temperature can more accurately represent real road situations with rising traffic loads and densities combined with climatic change. This method is more effective than traditional methods such as measuring the softening point and penetration. Complex shear modulus and pha
Pericyte Dynamics in Glioblastoma and Ischemic Stroke
Glioblastoma (GBM) and ischemic stroke represent two challenging brain pathologies which still lack an optimal therapeutic strategy. Central to these diseases are pericytes, mural cells that regulate blood-brain barrier (BBB) integrity, vascular stability, and immune responses. However, the diseasespecific alterations in pericytes that contribute to GBM progression and their influence on the posts
