Synthesis of Janus Polydiacetylene Sensor Particles with Thermochromism and Solvatochromism Properties

Small Structures, EarlyView.
Controlled fabrication of Janus polydiacetylene (PDA) microparticles is accomplished using a simple heating and cooling process in an aqueous solution. Janus PDA particles demonstrate potential for solvent sensing, with distinct solvatochromic behavior in each bulb.

Enhancing generalized spectral clustering with embedding Laplacian graph regularization

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

Molecular Retrosynthesis Top‐K Prediction Based on the Latent Generation Process

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT In the field of organic synthesis, the core objective of retrosynthetic methods is to deduce possible synthetic routes and precursor molecules for complex target molecules. Traditional retrosynthetic methods, such as template‐based retrosynthesis, have high accuracy and interpretability in specific types of reactions but are limited by the ...

A Matrix Exponential Generalization of the Laplace Transform of Poisson Shot Noise [PDF]

arXiv
We consider a generalization of the Laplace transform of Poisson shot noise defined as an integral transform with respect to a matrix exponential. We denote this as the matrix Laplace transform and establish that it is in general a matrix function extension of the scalar Laplace transform. We show that the matrix Laplace transform of Poisson shot noise

Towards a dynamic flow calculation method based on Schur complement for natural gas network

Energy Internet, EarlyView.
Abstract The energy transfer process of natural gas network (NGN) has remarkable dynamic characteristics. However, the model of the gas network dominated by partial differential equations (PDEs) is challenging to analyse due to its heterogeneous properties, high dimensionality, and significant non‐linearity.

Positive corona discharge of rod‐plate electrodes in high‐speed airflow

High Voltage, EarlyView.
Abstract The characteristics of positive corona discharge of rod electrode in high‐speed airflow are studied in this paper. The experiments were carried out in a wind tunnel with a maximum flow speed of 100 m/s in a dark room. The discharge voltage and current were recorded and the corona patterns were captured by a digital single lens reflex (DSLR ...

Multiphysics Simulation Methods in Computer Graphics

Computer Graphics Forum, EarlyView.
Abstract Physics simulation is a cornerstone of many computer graphics applications, ranging from video games and virtual reality to visual effects and computational design. The number of techniques for physically‐based modeling and animation has thus skyrocketed over the past few decades, facilitating the simulation of a wide variety of materials and ...

Revealing hidden sources of uncertainty in biodiversity trend assessments

Ecography, EarlyView.
Idiosyncratic decisions during the biodiversity trend assessment process may limit reproducibility, whilst ‘hidden' uncertainty due to collection bias, taxonomic incompleteness, and variable taxonomic resolution may limit the reliability of reported trends.

Theories of market selection

Journal of Economic Surveys, EarlyView.
Abstract We provide a survey of the main mechanisms of market selection used in economics. We categorize existing theories into three broad classes—evolutionary selection, reduced form selection, and rational equilibrium—based on their adopted selection mechanisms.

A Stochastic Tree for Bubble Asset Modelling and Pricing

Journal of Time Series Analysis, EarlyView.
ABSTRACT We introduce a new stochastic tree representation of a strictly stationary submartingale process for modelling, forecasting, and pricing speculative bubbles on commodity and cryptocurrency markets. The model is compared to other trees proposed in the literature on bubble asset modelling and stochastic volatility approximation. We show that the
