Postoperative Delirium and the Association to Continuously Monitored Severe Deviations of Vital Signs at the General Ward After Major Abdominal Surgery

ABSTRACT Background Delirium is the most frequent neurological complication after surgery and is associated with increased postoperative morbidity and mortality. The underlying pathophysiology is not fully understood, but is suggested to be multifactorial, including hypoperfusion...

Three-year trends in community opioid use disorder stigma in a rural Tennessee county

Stigma toward people with opioid use disorder (OUD) limits treatment engagement, particularly in underserved rural communities. This study examined three-year trends in OUD stigma among community members in a rural Tennessee county served by a federal opioid response program. Rep...

The Metabolic Universe: A Research Program

This program proposes that supermassive black holes are not terminal gravitational sinks but cyclic metabolic processors. Matter that falls toward them is dismantled into its subatomic baseline; the resulting three-dimensional volume information is compressed onto a two-dimension...

Projected impact of population-level multi-cancer early detection screening: a discrete event simulation analysis.

Cancer screening for multiple cancers simultaneously, rather than one cancer at a time, has emerged as a promising strategy for population-level cancer screening, largely driven by the advent and rapid development of liquid biopsy-based multi-cancer early detection (MCED) tests....

Green hydrogen promotion in Cameroon: Implications for sustainable development

This paper argues that green hydrogen could be a driver of the technological transformation of a small open economy well integrated into the global energy market. Green hydrogen development is key to a sustainable transition of the economy. It can replace CO 2 -intensive technolo...

Numerical simulation of nonlinear wave propagation under Type-1 and Type-2 fuzzy scenarios

Purpose This research aims to create and evaluate fuzzy numerical methods to solve the coupled Whitham–Broer–Kaup equations (cWBKEs). These equations are used to study nonlinear wave movement through shallow water waves (SSW) and related models. This research aims to improve unce...

Evidence in Networked Metaverse Systems: Comparability, Reproducibility, and Deployment

Metaverse research now spans immersive networking, edge computing, digital twins, semantic communication, artificial intelligence, security, interoperability, sustainability, and deployment. The field is technically rich, yet apparently similar results are frequently produced und...

Beyond CD4 counts: Multi‐biomarker assessment of estimated time since HIV ‐1 infection and risk factors for late diagnosis

BACKGROUND: Late diagnosis (LD) of HIV, defined as CD4 count <350 cells/μL or AIDS at diagnosis, remains a substantial public health challenge, with half of individuals in Europe diagnosed late. How long these individuals have lived with HIV remains unclear. We applied a multi-bi...

Advances in Photochemical Alkene Difunctionalization via Electron Donor–Acceptor (EDA) Complexes

Alkenes are ubiquitous and versatile feedstocks in organic synthesis. Alkene difunctionalization, which enables the simultaneous installation of two functional groups across the carbon–carbon double bond, represents a highly efficient strategy for constructing complex molecular a...

Thermally Reversible Transformation between Two Isomers of Silver Sulfide Magic-Size Clusters

Abstract Isomers of semiconductor magic-size clusters (MSCs) share the same molecular formula but can exhibit distinct optical and electronic properties. Most of the reported MSC isomers have been so far limited to cadmium chalcogenides. Herein, we report the reversible transform...

Money Creation for Crypto Space: Stablecoins or Central Bank Digital Currencies?

Stablecoins are the current go-to digital money to settle transactions on the blockchain. We explore the implications of introducing competing tokenized public digital monies (i.e., tokenized central bank digital currencies (CBDCs)). When they pay a moderate interest rate and gua...

Use of Recycled Low-Density Polyethylene for Production of Asphalt Mixture: Performance and Emission Characteristics

Abstract Recycled plastic modified asphalt mixtures show varied performance due to the variability in dosage, differences in source of materials, incorporation method, inconsistency in modification techniques, and absence of global standardization. This study addresses the existi...

A targeted review on pollution, sources and risks associated with PCBs in soil and sediment in Nigeria

ABSTRACT A graphical diagram showing the sources, exposure routes and health risk of PCBs in contaminated soil and sediment in Nigeria. Polychlorinated biphenyls (PCBs) pose significant environmental risks globally, particularly in underdeveloped countries with inadequate waste h...

A KK-theoretic note on the spectral localiser

Abstract We review the construction of the spectral localiser (due to Loring and Schulz-Baldes) from a KK -theoretic perspective. We first give a KK -theoretic argument providing a spectral flow expression for the even or odd index pairing in terms of the “infinite volume” spectr...

Artificial intelligence driven framework for enhancing sustainability and resilience in communal cattle insurance in Lupane District Zimbabwe

Communal cattle farming in Sub-Saharan Africa continues to face destabilization from non-linear climate variability, yet insurance penetration remains negligible. In Lupane District, Zimbabwe, uptake is exceptionally low at approximately 0.01%, despite recurrent droughts that thr...

Reconfiguring Rubberwood Starch from a Weak Link to a Protective Shield against Decay and Mold

Abstract Starch has long been regarded as a critical weakness limiting rubberwood’s construction applications due to its hygroscopicity and mold susceptibility. Instead of removing or chemically modifying this component, we develop a green hydrothermal and controlled drying strat...

A modern reconstruction and analysis framework for the ILD ZHH study

Abstract Measuring the Higgs potential represents one of the main goals of the physics programs of future colliders. At center-of-mass energies of $$\sqrt{s} \ge {500\,\mathrm{\text {G}\text {eV}}}$$ s ≥ 500 G , direct access to the self-coupling $$\lambda$$ λ is enabled through...

Undecidability as a Structural Invariant from Computability to Quantum Physics — E8 Intelligence Research

FINDING: Undecidability is not a peripheral paradox but a structural invariant of formal systems, extending from classical computability (halting problem) into quantum many-body physics, where spectral gaps and ground-state properties become provably non-computable. | MATH: Halti...

Potential, challenges, and opportunities in the development of geothermal energy projects

Geothermal energy is an important yet insufficiently explored renewable source. Known for its supply stability and low environmental impact, it offers significant potential, however, broader adoption faces notable technical, economic, and regulatory challenges. This paper first e...

Hybrid Physics-Informed Machine Learning via residual fitting for the prediction of creep and shrinkage in concrete

Abstract Recent works about data-driven analysis of concrete creep and shrinkage have enhanced structural analysis, providing more efficient results compared to standard models. Moreover, recent studies have shown strong efficiency when physics laws are coupled with machine learn...
