Maximum likelihood q-estimator reveals nonextensivity regulated by extracellular potassium in the mammalian neuromuscular junction
πŸ‘€ A. J. da Silva; M. A. S. Trindade; D. O. C. Santos; R. F. Lima

Recently, we demonstrated the existence of nonextensivity in neuromuscular transmission [Phys. Rev. E 84, 041925 (2011)]. In the present letter, we propose a general criterion based on the q-calculus foundations and nonextensive statistics to estimate the values for both scale factor and q-index using the maximum likel…

Quantifying the Dynamics of Consciousness using Hierarchical Integration, Organised Complexity and Metastability
πŸ‘€ Hassan Ugail; Newton Howard

Quantifying the neural signatures of consciousness remains a major challenge in neuroscience and AI. Although many theories link consciousness to rich, multiscale, and flexible neural organisation, robust quantitative measures are still lacking. This paper presents a theory-neutral framework that characterises consciou…

The Importance of Being Negative: A serious treatment of non-trivial edges in brain functional connectome
πŸ‘€ Liang Zhan; Lisanne M. Jenkins; Ouri E. Wolfson; Johnson J. GadElkarim; Kevin Nocito; Paul M. Thompson; Olusola A. Ajilore; Moo K. Chung; Alex D. Leow

Understanding the modularity of fMRI-derived brain networks or connectomes can inform the study of brain function organization. However, fMRI connectomes additionally involve negative edges, which are not rigorously accounted for by existing approaches to modularity that either ignores or arbitrarily weight these conne…

Recurrence interval analysis of high-frequency financial returns and its application to risk estimation
πŸ‘€ Fei Ren; Wei-Xing Zhou

We investigate the probability distributions of the recurrence intervals $Ο„$ between consecutive 1-min returns above a positive threshold $q>0$ or below a negative threshold $q<0$ of two indices and 20 individual stocks in China's stock market. The distributions of recurrence intervals for positive and negative thresh…

QLAMMP: A Q-Learning Agent for Optimizing Fees on Automated Market Making Protocols
πŸ‘€ Dev Churiwala; Bhaskar Krishnamachari

Automated Market Makers (AMMs) have cemented themselves as an integral part of the decentralized finance (DeFi) space. AMMs are a type of exchange that allows users to trade assets without the need for a centralized exchange. They form the foundation for numerous decentralized exchanges (DEXs), which help facilitate th…

Recurrence interval analysis of trading volumes
πŸ‘€ Fei Ren; Wei-Xing Zhou

We study the statistical properties of the recurrence intervals $Ο„$ between successive trading volumes exceeding a certain threshold $q$. The recurrence interval analysis is carried out for the 20 liquid Chinese stocks covering a period from January 2000 to May 2009, and two Chinese indices from January 2003 to April …

On two quantum approaches to adaptive mutations in bacteria
πŸ‘€ Vasily Ogryzko

I compare two quantum-theoretical approaches to the phenomenon of adaptive mutations, termed here Q-cell and Q-genome. I use 'fluctuation trapping' model as a general framework. I introduce notions of R-error and D-error and argue that the 'fluctuation trapping' model has to employ a correlation between the R- and D- e…

Predicting Expressive Speaking Style From Text In End-To-End Speech Synthesis
πŸ‘€ Daisy Stanton; Yuxuan Wang; RJ Skerry-Ryan

Global Style Tokens (GSTs) are a recently-proposed method to learn latent disentangled representations of high-dimensional data. GSTs can be used within Tacotron, a state-of-the-art end-to-end text-to-speech synthesis system, to uncover expressive factors of variation in speaking style. In this work, we introduce the T…

Electron Electric Dipole Moment and Hyperfine Interaction Constants for ThO
πŸ‘€ Timo Fleig; Malaya K. Nayak

A recently implemented relativistic four-component configuration interaction approach to study ${\cal{P}}$- and ${\cal{T}}$-odd interaction constants in atoms and molecules is employed to determine the electron electric dipole moment effective electric field in the $Ξ©=1$ first excited state of the ThO molecule. We obt…

Quantum mechanics in general quantum systems (II): Perturbation theory
πŸ‘€ An Min Wang

We propose an improved scheme of perturbation theory based on our exact solution [An Min Wang, quant-ph/0611216] in general quantum systems independent of time. Our elementary start-point is to introduce the perturbing parameter as late as possible. Our main skills are Hamiltonian redivision so as to overcome a flaw of…
