High resolution Ordovician carbon isotope chemostratigraphy in South China and its significance for global correlation

Based on the Shidi-1 drill core, this paper presents new and highly time resolved carbon isotope data (δ13Ccarb) for the Early Ordovician through Early Silurian of the Yangtze Platform, South China. Five carbon isotopic shifts (C1-C5) through the late Tremadocian to the Katian have been recognized in the Shidi-1 drill core recordings. Together with previously published isotope data, a composite ca

Psychologism in the study of children's semiotic development

This essay discusses the notion of 'semiotic development in child development' and highlights potential concerns for 'psychologism' when semiotics turns into cognitive semiotics. The notion of 'semiotic development in child development' indicates a transdisciplinary approach involving both semiotics, the general study of meaning and signs, and child psychology. This, however, invites the criticism

Preventive cognitive protection based on AAV9 overexpression of IGF1 in hippocampal astrocytes

Astrocytes play key roles in the brain. When astrocyte support fails, neurological disorders follow, resulting in disrupted synaptic communication, neuronal degeneration, and cell death. We posit that astrocytes overexpressing neurotrophic factors, such as Insulin Like Growth Factor 1 (IGF1), prevent the onset of neurodegeneration. We overexpressed IGF1 and the reporter TdTomato (TOM) in hippocamp

Search for charged-lepton-flavor violating Formula Presented interactions in top-quark production and decay in Formula Presented collisions at Formula Presented with the ATLAS detector at the LHC

A search for charged-lepton-flavor violating Formula Presented (Formula Presented, Formula Presented) interactions is presented, considering both top-quark production and decay. The data analyzed correspond to Formula Presented of proton-proton collisions at a center-of-mass energy of Formula Presented recorded with the ATLAS detector at the Large Hadron Collider. The analysis targets events conta

The Transformative Potential of the Craft Imaginary - A Study on Craft Brewing

Craft has been a steady adversary to the proliferation of industrialization. As an imaginary of embodied work, mainly driven by intrinsic motivation and by a strive for excellence, craft is increasingly re-emerging in discussions on improving current forms of work. A common theme across research on craft is its potential to address alienation as one of the main pathologies of modern work. We study

Simulation-based consequence analysis of reinforced-concrete buildings subjected to earthquake- and environment-induced damage accumulation

Structural systems in seismic-prone regions can experience sudden deterioration caused by earthquake-induced ground-motion sequences. In addition, given the prevailing environmental conditions at their site, these systems may undergo gradual deterioration resulting from environment-induced mechanisms. The combined impacts of such phenomena can result in significant structural/non-structural damage

Modeling deterioration and predicting remaining useful life using stochastic differential equations

The deterioration of engineering systems might reduce the system reliability and prompt maintenance operations that may disrupt the ability of the systems to provide regular service. Estimating the Remaining Useful Life (RUL) of the system requires an understanding of the deterioration processes acting on it. Recent formulations have shifted the focus of deterioration modeling from the system as a

Phylogenomics and biogeography of sawflies and woodwasps (Hymenoptera, Symphyta)

Phylogenomic approaches have recently helped elucidate various insect relationships, but large-scale comprehensive analyses on relationships within sawflies and woodwasps are still lacking. Here, we infer the relationships and long-term biogeographic history of these hymenopteran groups using a large dataset of 354 UCE loci collected from 385 species that represent all major lineages. Early Hymeno

Random effects during training : Implications for deep learning-based medical image segmentation

Background: A single learning algorithm can produce deep learning-based image segmentation models that vary in performance purely due to random effects during training. This study assessed the effect of these random performance fluctuations on the reliability of standard methods of comparing segmentation models. Methods: The influence of random effects during training was assessed by running a sin

Punishment Moralism

In this paper, I try to reconcile the vulgar (normative) definition of punishment with the positivistic (purely descriptive) definition that separates the ethics of punishment from its definition—punishment positivism. I will argue that although the vulgar definition has critical issues, this does not mean that we should stop using normative concepts in the definition of punishment. I will attempt

Experimental and kinetic modelling study on the laminar burning velocities of ultra-lean n-heptane flames at atmospheric pressure

Ultra-lean combustion is a promising strategy for enhancing engine efficiency and reducing pollutant emissions. In the present study, laminar burning velocity, SL, of n-heptane, a key gasoline surrogate component, was measured at 298 K and 1 atm using the heat flux method. The experimental conditions cover ultra-lean conditions with an equivalence ratio as low as 0.5 that have never been reported

Probing the strength of radial migration via churning by using metal-rich red giant stars from APOGEE

Making use of the APOGEE DR17 catalogue with high quality data for 143 509 red giant branch stars we explore the strength of different mechanisms that causes a star to radially migrate in the Milky Way stellar disc. At any position in the disc we find stars that are more metal-rich than the local interstellar medium. This is surprising and normally attributed to the migration of these stars after

Dynamics of Aedes aegypti mating behaviour

The use of pheromones, while common, remains underexplored in mosquito research. Understanding Aedes aegypti's mating behaviour and pheromones is crucial for expanding knowledge and advancing vector control strategies. Unlike other species, Aedes mosquitoes have adaptable mating behaviour, complicating the study of their communication mechanisms. Current literature on Aedes communication is sparse

Statistical Combination of ATLAS Run 2 Searches for Charginos and Neutralinos at the LHC

Statistical combinations of searches for charginos and neutralinos using various decay channels are performed using 139 fb^{-1} of pp collision data at sqrt[s]=13 TeV with the ATLAS detector at the Large Hadron Collider. Searches targeting pure-wino chargino pair production, pure-wino chargino-neutralino production, or Higgsino production decaying via standard model W, Z, or h bosons are combined
