Adsorption of hydrogen on stable and metastable Ir(100) surfaces

Using the combination of high resolution core level spectroscopy and density functional theory we present adetailed spectroscopic study for all clean and hydrogen covered phases of Ir(100). The results are complementedby an investigation of the hydrogen desorption process from various phases using temperature programmeddesorption spectroscopy and scanning tunneling microscopy. In total, all experi

Heterogeneously catalyzed lignin depolymerisation in continuous flow : Assessing feedstock pretreatment and catalyst deactivation

Due to the large-scale production of lignin, continuous flow reactors are preferred for its further valorization through depolymerization. However, there is limited literature on their use in lignin depolymerization, especially concerning feedstock pretreatments and catalyst deactivation. Therefore, in this study, the impact of a batch solvolysis pretreatment on the mild reductive catalytic depoly

A pilot study of AI-assisted reading of prostate MRI in Organized Prostate Cancer Testing

Objectives: To evaluate the feasibility of AI-assisted reading of prostate magnetic resonance imaging (MRI) in Organized Prostate cancer Testing (OPT). Methods: Retrospective cohort study including 57 men with elevated prostate-specific antigen (PSA) levels ≥3 µg/L that performed bi-parametric MRI in OPT. The results of a CE-marked deep learning (DL) algorithm for prostate MRI lesion detection wer

Trajectory Analysis of the Four-Year Changes in Body Composition and Bone Mineral Characteristics Among Highly Competitive Male University Long-Distance Runners

Objectives: This study examined long-term changes in body composition and bone mineral characteristics among male long-distance runners from a high-profile university team, focusing on concerns about impaired musculoskeletal development due to extreme leanness and weight management practices in this population. Methods: Trajectory analyses were performed using multilevel modeling of 608 dual-energ

Plant Phenology Index leveraging over conventional vegetation indices to establish a new remote sensing benchmark of GPP for northern ecosystems

Northern ecosystems, encompassing boreal forests, tundra, and permafrost areas, are increasingly affected by the amplified impacts of climate change. These ecosystems play a crucial role in determining the global carbon budget. To improve our understanding of carbon uptake in these regions, we evaluate the effectiveness of employing the physically-based Plant Phenology Index (PPI) to estimate gros

D-Dimer in Acute Mesenteric Venous Thrombosis: A Prospective Case-Control International Multicenter Study

Background:Acute mesenteric venous thrombosis (MVT) is rarely suspected as primary diagnosis in emergency departments and still carries an in-hospital mortality rate of above 20%.Objectives:The aim of this study was to find differences in clinical and laboratory markers between patients with acute MVT and a control group of suspected but confirmed as not having any type of acute mesenteric ischaem

Rb-promoted Fe/CeO2 nanocatalyst for aniline conversion into azoxybenzene, DFT calculations and mechanism

Selectivity control of aniline oxidation and low reactant conversion in traditional synthesis methods are great challenges, and it is desirable to develop a green, low-cost and highly efficient catalytic route toward value-added products. Herein, an Rb-promoted Fe/CeO2 nanocatalyst was prepared to understand the effects of Rb-promoter on the catalytic performance for the selective oxidation of ani

Five-year carry-over effects in dune slack vegetation response to hydrology

Dune slacks are biodiverse seasonal wetlands within sand dune systems, strongly influenced by the dynamics of the local groundwater regime. Future climate predictions indicate strong adverse impact on the hydrology and therefore ecology of these wetland ecosystems. In this study we aimed to find the most appropriate hydrological and ecological indicators to summarise dune slack plant community res

Ensemble estimates of global wetland methane emissions over 2000-2020

Due to ongoing climate change, methane (CH4) emissions from vegetated wetlands are projected to increase during the 21st century, challenging climate mitigation efforts aimed at limiting global warming. However, despite reports of rising emission trends, a comprehensive evaluation and attribution of recent changes remains limited. Here we assessed global wetland CH4 emissions from 2000-2020 based

Clinical response of the novel activating ALK-I1171T mutation in neuroblastoma to the ALK inhibitor ceritinib

Tumors with anaplastic lymphoma kinase (ALK) fusion rearrangements, including non-small-cell lung cancer and anaplastic large cell lymphoma, are highly sensitive to ALK tyrosine kinase inhibitors (TKIs), underscoring the notion that such cancers are addicted to ALK activity. Although mutations in ALK are heavily implicated in childhood neuroblastoma, response to the ALK TKI crizotinib has been dis

ECG-Based Detection of Acute Myocardial Infarction Using a Wrist-Worn Device

Background: A wrist-worn wearable device for acquiring limb and chest ECG leads (wECG) may constitute a promising approach to detection of acute myocardial infarction (AMI). However, it remains to be demonstrated whether the information conveyed by the wECG is sufficient for AMI detection. Objective: To explore explainable machine learning models for detecting AMI using the wECG. Methods: Two type

Shared Battlegrounds: War at the Crossroads of Environmental History and the History of Science

In recent years, the environmental impact of warfare has made front-page news. Discussions about “ecocide”—a term first proposed in 1970 by Yale biologist Arthur W. Galston to describe the large-scale destruction of ecosystems during the Vietnam War—have come into the spotlight. The preparation and conduct of war, along with the social, economic, and scientific reorganisation that accompany it, of

Luminescence chronology of the Velika Vrbica loess-palaeosol sequence (Wallachian Basin): Evaluating quartz and K-feldspar signals from MIS 5 to the Holocene

The Velika Vrbica loess-palaeosol sequence, situated on the south-western bank of the Danube River in northeastern Serbia, represents one of the key Quaternary records in the lower Danube basin, covering the MIS 5-MIS 1 period. Previous investigations of the upper 500 cm established a high-resolution chronology and revealed unexpected patterns of dust accumulation during interstadial phases. In th

Graphene Encapsulated Ni Catalyzed Reductive Amination of VOC Aldehydes to High Value Chemicals by industrial continuous flow synthesis

Volatile organic compounds (VOCs) include many types of organic compounds, such as alkanes, olefins, aldehydes, etc. They have attracted widespread attention in various fields such as food and flavor analysis, environmental and atmospheric research, safety, or healthcare. Developing efficient, practical, and high-value industrial VOC utilization technologies is crucial for sustainable social and h

C-terminal Modifications and Short Oligopeptide Mimetics of Pancreatic Polypeptides in Y4 Receptor Activation

Pancreatic polypeptide (PP) is a gut-derived hormone of the neuropeptide Y family that regulates appetite, gastrointestinal motility, and energy homeostasis through activation of the neuropeptide Y4 receptor (Y4R). With the rising prevalence of obesity, understanding the molecular pharmacology and structure-function relationships of PP-Y4R interactions is essential for the development of novel ant

In-situ NAP-XPS reveals water-induced phase segregation of MoS2 nanoparticles in hydrodeoxygenation catalysis

Hydrodeoxygenation (HDO) is a catalytic process applied for the reduction of oxygen levels in hydrocarbons from bio-derived feedstock as part of the processing into renewable fuel. The MoS2-based hydrotreating catalysts, currently being applied for the HDO reaction, are exposed to a complex environment consisting of O-rich hydrocarbons and water, which adversely impacts the state and stability of
