Secular Mysticism: Entanglements of Science and Religion in Psychedelic Medicine
Psychedelic medicine is a rapidly growing, billion-dollar industry poised to transform mental health care by incorporating spiritual experiences into clinical psychiatry. However, while the blending of psychiatry and mystical experience has long made this field unique, the blurred boundaries between science and spiritual practice have sparked increasing public debate. What does...
Classical Logical Coherentism
Our usual explication of a logic through an axiomatic calculus is structurally foundationalist. Justification gets transferred by applying rules finitely many times from already justified sentences to new sentences in a linear-like fashion, by starting from a base of non-to-be justified sentences (i.e. the axioms). In contrast, this paper develops a coherentist approach to...

Dynamics near the ground state for the Sobolev critical Fujita equation in 6D
This paper investigates the asymptotic behavior of solutions to \(u_t=\Delta u+|u|^{p-1}u\) in the Sobolev critical case. Our main result is a classification of the dynamics near the ground states in the six dimensional case. It is shown that if the initial data \(u_0\in H^1({\mathbb R}^6)\) satisfies \(\Vert u_0-\textsf{Q}\Vert _{\dot{H}^1({\mathbb R}^6)}\ll 1\), then the...
The meiotic achilles’ heel: vulnerability and resilience under environmental stress
Plant meiosis constitutes a critical vulnerability under unfavorable conditions in plant reproduction. In the 21st century, with the accelerating global climate change, environmental stresses increasingly compromise fertility and genetic stability. This review examines the role of abiotic stress factors - including heat, cold, drought, salinity, heavy metals, and oxidative stress...
Austempering Analysis of Diesel Fuel Pump Pressure Vessel
The research focuses on the modification of the microstructure in high-pressure diesel engines through improvements in the austempering process. Unstable conditions during the austempering treatment led to the formation of undesirable microstructural features, including non-uniform subsurface decarburization, excessive carbide precipitation, and regions of pearlitic phases due to...
Beyond the Law: Uncovering the economic thought of Bruno Leoni
This article reconstructs the economic dimension of Bruno Leoni’s thought, focusing on a part of his work that has often remained in the background when his legacy is approached primarily through legal and political lenses. Drawing on his essays and reviews in Il Politico, together with Freedom and the Law and later collected papers, the study shows that Leoni engaged in a...
A unique case of unexpected electrocution inflicted by a single dry cell battery in very low voltage (9 V)
Background Although electrocutions commonly occur at domestic voltages of 100–240 V worldwide, fatal electrical injuries at voltages below 100 V are uncommon. We report an unusual fatal case of electrocution associated with a single 9 V dry cell battery. Case presentation A man in his 30s was found dead with metal wires inserted into the skin of his chest. The wires were...
Markless Alignment Process of Superimposed Patterns with Different Shapes Using Fourier Spectral Analysis
Alignment accuracy of micropatterns is a critical factor affecting the performance of products in industrial applications. In multilayer structures, where patterns of different shapes must be precisely superimposed, even slight misalignments can significantly degrade performance, necessitating high-precision alignment. Conventional alignment techniques rely on alignment marks...
Lumped parameter modeling of changes in liver hemodynamics due to cirrhosis
This numerical study employs a computational model of human hepatic blood flow to investigate the hemodynamic consequences of cirrhosis. The liver receives blood through a dual-inlet system (portal vein and hepatic artery) that perfuses a complex network of sinusoids; however, cirrhosis-induced fibrosis distorts these channels, increasing hydraulic resistance. In turn, portal...
Scaling Approaches for Manning’s Roughness Coefficient in Reduced-Scale Hydrodynamic River Simulations With Delft3D
Despite extensive theoretical work on Manning’s roughness coefficient (n) in hydraulic literature, its numerical validity across multiple scales in two-dimensional depth-averaged (2DH) frameworks remains poorly quantified. This study addresses this gap by developing a systematic multi-scale calibration protocol applied to a complex reach of a large alluvial river. The novelty...
Stellar Astrophysics in the Ultraviolet: Setting the Scene
The ultraviolet (UV) spectral domain occupies a unique position in stellar astrophysics, serving as the bridge between the thermal continuum of photospheres and the high-energy, non-thermal processes of stellar coronae and winds. This article provides a review of stellar physics in the UV, addressing both the theoretical framework and observational applications across the...
Ameloglyphics: a novel forensic tool for species identification and individual characterisation
Introduction Ameloglyphics, the study of enamel rod-end patterns, or "tooth prints," has emerged as a promising forensic tool. Its application in human identification is documented, but data on comparative morphology across human and non-human mammalian species remain limited. Differentiating the species is crucial in forensic contexts such as mass disasters, wildlife forensics...
Recent insights into the plant ARP2/3 complex
More than two decades have passed since the first identification of the ARP2/3 complex in plants. During this time, numerous studies have advanced our understanding of the complex’s role in actin cytoskeleton regulation. However, compared with opisthokonts, the mechanisms and functional contexts of ARP2/3 activity in plants remain only partially understood. Since the last...

Purpose of review We aim to evaluate the efficacy of risk-based surveillance strategies for hepatocellular carcinoma (HCC) in chronic hepatitis B virus (HBV) patients, addressing key questions: How can risk stratification enhance early detection? What are cost-effective approaches across diverse settings? How may novel diagnostic tools enhance surveillance? Recent findings Recent...
A mathematical model of osteocyte network control of bone mechanical adaptation
The osteocyte network embedded in bone tissues plays a central role in the control of bone adaptation to mechanical loads and micro-damage repair. However, much remains to be understood about the precise mechanisms by which the osteocyte network regulates bone formation and bone resorption based on the propagation of biochemical signals emitted in response to mechanical stimulus...
Rapid Generation of Urban Flood Susceptibility Maps Using Machine Learning Under Different Rainfall Scenarios
Urban floods increasingly pose threats to transportation systems, residential areas, and public safety, which has created an urgent need for rapid urban flood susceptibility mapping (UFSM) under varying rainfall conditions. In this study, five tree-based machine learning models, namely, random forest (RF), extreme gradient boosting (XGBoost), light gradient boosting machine...
A dependent and censored first hitting-time model with compound Poisson processes
We consider a bivariate first hitting-time model in which durations are the crossing times of dependent compound Poisson processes with fixed thresholds. The identifiability of the model is discussed, and likelihood estimators of the model parameters are proposed. We obtain the asymptotic properties of the estimators and underline their finite sample performance with a simulation...
