From Mathematical Foundation to Open Experimental Program: A Revised Unified Account of the Total Wave Modified Schrödinger Equation (TWMSE)

This paper presents a revised unified account of the Total Wave Modified Schrödinger Equation (TWMSE), a proposed deterministic collapse framework in which quantum state reduction is investigated as a possible dynamical consequence of interaction between a system wavefunction and...

Dictionary-KAN: Resolving the Optimization Paradox of Kolmogorov-Arnold Networks via Complex RKHS, Machine-Verified Theory, and Discrete Hierarchical Refinement

Kolmogorov-Arnold Networks (KANs) replace dense weight matrices with learnable univariate edge functions, but continuous spline-based formulations suffer from an “optimization paradox”: vanishing gradients, knot-sorting collapses, dense-grid memory costs, and the reintroduction o...

Does TikTok promote or cannibalize music streaming? Estimands and identification with heavy-tailed outcomes

Abstract We study how TikTok affects demand for music on paid streaming platforms in the context of Universal Music Group’s (UMG) global withdrawal of its catalog from TikTok. Recent studies using this quasi-natural experiment have reached different conclusions about whether TikT...

On exact estimates of the order of approximation of functions of several variables in the anisotropic Lorentz--Zygmund space

In this paper we consider $L_{\overline{p}, \overline\alpha, \overline{\tau}}^{*}(\mathbb{T}^{m})$ anisotropic Lorentz-Zyg\-mu\-nd space $ 2\pi$ of periodic functions of $m$ variables and Nikol'skii--Besov's class $S_{\overline{p}, \overline\alpha, \overline{\tau}, \bar{\theta}}^...

Bootstrapping Generalization Error Bounds for Time Series

Abstract We consider the problem of constructing confidence intervals for the risk of forecasting the future of a stationary, ergodic stochastic process, using a model estimated from the past of the process. We show that a bootstrap procedure provides valid confidence intervals f...

A tutorial on fitting flexible meta-analytic models with structural equation modeling in R

Abstract There are various statistical models with different features and assumptions in meta-analysis. Popular models include the fixed-effect (or common effect), random-effects, and mixed-effects models. Apart from these models, several alternative models, such as the multiplic...

Expected reward value and reward prediction errors reinforce but also interfere with human time perception

Abstract Time perception is often investigated in animal models and in humans using instrumental paradigms where reinforcement learning (RL) and associated dopaminergic processes have modulatory effects. For example, interval timing, which includes the judgment of relatively shor...

The money laundering market: An economic analysis

Criminals launder their proceeds from crime, either themselves or by paying a professional, to disguise the link between the criminal, the crime, and the proceeds. This allows the criminal to spend the proceeds more freely and lowers the chance of receiving unwanted attention fro...

The illegal market for sex in the United States: Insights from economic research

The illegal market for sex in the United States generates significant economic activity yet remains understudied due to its illegality and clandestine nature. This paper synthesizes existing empirical evidence documenting aspects of market structure, impacts of regulation, and no...

Delivering Organisational Judgement: Explicit Context, Retrieval, and Parameter Adaptation in Qwen3

Synthetic withholding studies show that organisation-specific engineering judgement can be restored when written material is supplied at inference time. This technical note asks whether the same sealed contrasting-practices world admits recovery when that judgement is delivered t...

A budding science of illegal markets

Illegal markets create untold societal and environmental harm, but they have attracted surprisingly little scholarly attention. This paper explores illegal markets as a class of objects. It considers similarities and differences across markets, with particular attention to nine:...

Osimertinib With or Without Chemotherapy in Advanced Non–Small Cell Lung Cancer With EGFR and Concurrent TP53 Mutations

Importance: Combination therapy has emerged as a promising therapeutic approach for patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC). However, its clinical benefit-risk profile remains a focus of ongoing debate. Identifying patients...

Changing models in cultural evolution: from (quasi-)Darwinian to ecological mechanisms: A commentary on ‘Quasi-Darwinian mechanisms: ecological inheritance and cumulative culture’ by Kim Sterelny

Kim Sterelny’s analysis of cultural learning moves cultural evolution theory away from Darwinian models toward cognition, ecological scaffolding and incentives. We argue his insights warrant a more radical conclusion: cultural evolution needs no Darwinian vocabulary, even in its...

Illegal markets for cigarettes and e-cigarettes

This paper discusses the long-standing illegal markets for cigarettes and the more recently emerged illegal markets for e-cigarettes. We identify three distinctive market fundamentals that help explain many features of the illegal markets. First, in contrast to some illegal goods...

The Dutch cardiomyopathy registry (DCR); rationale and registry design

BACKGROUND: Cardiomyopathies are important causes of arrhythmias, sudden cardiac death, and heart failure. With accumulating knowledge in clinical, genetic, and molecular phenotyping, the number of distinct disease entities is growing. There is a need for broad, inclusive, high-q...

Structure and dynamics in metallic glasses from nanodiffraction

Abstract Medium-range structure at a length scale between ~0.5 and 3 nm strongly influences the properties and phase transformations of metallic glass alloys. Electron diffraction methods based on four-dimensional scanning transmission electron microscopy are well suited for char...

A national-scale assessment of the impact of canals on urban temperatures

Abstract Urban populations are particularly vulnerable to heat-related mortality and morbidity. Climate-responsive urban design, which can include development of green and bluespaces, has the potential to offset climate change-related impacts. Compared to greenspaces, the effects...

Human ticklishness is a widespread, culturally shared and bodily organized sensory experience

Abstract Human ticklishness is one of the oldest yet unresolved scientific puzzles. As early as the time of Aristotle and Socrates, scholars have speculated on its origins and function, but fundamental questions remain. Is ticklishness culturally shared or specific? Does it follo...
