Multi-scale description of pedestrian collective dynamics with port-Hamiltonian systems
πŸ‘€ Antoine Tordeux; Claudia Totzeck

Port-Hamiltonian systems (PHS) theory is a recent but already well-established modelling approach for non-linear physical systems. Some studies have shown lately that PHS frameworks are relevant for modelling and control of swarm and multi-agent systems. We identify in this contribution a general class of microscopic f…

The politics of physicists social models
πŸ‘€ Pablo Jensen

I give an overview of the topic of this special issue, the applications of (statistical) physics to social sciences at large. I discuss several examples of simple social models put forward by physicists and discuss their interest. I argue that while they may be conceptually useful to correct our intuitive models of soc…

Comment on astro-ph/0507588 and astro-ph/0508483
πŸ‘€ Daniel E. Reichart

Guidorzi has now written two papers (astro-ph/0507588 and astro-ph/0508483, both accepted to MNRAS) on the GRB variability-luminosity correlation in which he finds that expanded samples of L vs. V data are not well described by a power law because the scatter of the data around such a model is more than can be accounte…

On the Availability of ESO Data Papers on arXiv/astro-ph
πŸ‘€ Uta Grothkopf; Dominic Bordelon; Silvia Meakins; Eric Emsellem

Using the ESO Telescope Bibliography database telbib, we have investigated the percentage of ESO data papers that were submitted to the arXiv/astro-ph e-print server and that are therefore free to read. Our study revealed an availability of up to 96% of telbib papers on arXiv over the years 2010 to 2017. We also compar…

Multiplicative Langevin Process for Volatilities Produces Observed Q-Variance Regularities
πŸ‘€ William H. Press; Alex Dannenberg

Q-variance (so-called) posits a statistical relationship $\mathbf{E}(Οƒ^2 | z) = Οƒ_0^2 + \tfrac{1}{2}z^2$ between an asset's volatility $Οƒ^2$, as observed in a time interval $T$, and its (suitably scaled) return $z$ in the same interval. We here show that this relationship is {\em exactly equivalent} to to positing a…

Quantum Walks-Based Adaptive Distribution Generation with Efficient CUDA-Q Acceleration
πŸ‘€ Yen-Jui Chang; Wei-Ting Wang; Chen-Yu Liu; Yun-Yuan Wang; Ching-Ray Chang

We present a novel Adaptive Distribution Generator that leverages a quantum walks-based approach to generate high precision and efficiency of target probability distributions. Our method integrates variational quantum circuits with discrete-time quantum walks, specifically, split-step quantum walks and their entangled …

Valuation of Exotic Options and Counterparty Games Based on Conditional Diffusion
πŸ‘€ Helin Zhao; Junchi Shen

This paper addresses the challenges of pricing exotic options and structured products, which traditional models often fail to handle due to their inability to capture real-world market phenomena like fat-tailed distributions and volatility clustering. We introduce a Diffusion-Conditional Probability Model (DDPM) to gen…

Bio-JOIE: Joint Representation Learning of Biological Knowledge Bases
πŸ‘€ Junheng Hao; Chelsea Ju; Muhao Chen; Yizhou Sun; Carlo Zaniolo; Wei Wang

The widespread of Coronavirus has led to a worldwide pandemic with a high mortality rate. Currently, the knowledge accumulated from different studies about this virus is very limited. Leveraging a wide-range of biological knowledge, such as gene ontology and protein-protein interaction (PPI) networks from other closely…

Optimizing Native Ion Mobility Q-TOF in Helium and Nitrogen for Very Fragile Noncovalent Interactions
πŸ‘€ ValΓ©rie Gabelica; Sandrine Livet; FrΓ©dΓ©ric Rosu

The meaningful comparison of ion mobility (IM) results and of collision cross section (CCS) values on different platforms is a prerequisite for using CCS for identification or structural assignment. The amount of internal energy imparted to the ions prior to the ion mobility cell is a source of experimental variation. …

Modeling biological systems with delays in Bio-PEPA
πŸ‘€ Giulio Caravagna; Jane Hillston

Delays in biological systems may be used to model events for which the underlying dynamics cannot be precisely observed, or to provide abstraction of some behavior of the system resulting more compact models. In this paper we enrich the stochastic process algebra Bio-PEPA, with the possibility of assigning delays to a…
