On 3‐MMC: A Cathinone I Have Come to Know and Love

Anthropology of Consciousness, EarlyView.
ABSTRACT This article attempts to complicate the mythology of a compound in a state of becoming. I will trace lightly its origins as a cultural disruptor and how I am implicated in this imperative. Introducing you to 3‐MMC will require multiple modes of storytelling and taking of liberties, drawing on literature reviews, practice‐based research, prose,

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

A unified phase-matching mechanism for bio-inspired propulsion and vortex-induced energy harvesting in Kármán streets

Engineering Applications of Computational Fluid Mechanics
Fish swimming in unsteady environments can exploit the Kármán vortex streets generated by upstream obstacles to reduce energetic cost or enhance propulsion, offering inspiration for bio-inspired marine energy harvesting. Using a two-dimensional numerical

Modeling and Experimenting [PDF]

, 2009
Experimental activity is traditionally identified with testing the empirical implications or numerical simulations of models against data. In critical reaction to the ‘tribunal view’ on experiments, this essay will show the constructive contribution of ...

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Analysis of flow and energy dissipation in pump turbine with small guide vane opening

Engineering Applications of Computational Fluid Mechanics
In this study, a detailed flow state analysis of a reversible pump turbine (RPT) under small guide vane opening conditions was conducted using both numerical simulation and experimental methods on three analysis planes at 0.5 span. The entropy production

Generation of large-scale vortex dislocations in a three-dimensional wake-type flow [PDF]

, 2001
Numerical study of three-dimensional evolution of wake-type flow and vortex dislocations is performed by using a compact finite diffenence-Fourier spectral method to solve 3-D incompressible Navier-Stokes equations.

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.
