Cryptocurrency trading: a comprehensive survey

open access: yesFinancial Innovation, 2022
In recent years, the tendency of the number of financial institutions to include cryptocurrencies in their portfolios has accelerated. Cryptocurrencies are the first pure digital assets to be included by asset managers.

Not all the bots are created equal:the Ordering Turing Test for the labelling of bots in MMORPGs [PDF]

open access: yes, 2017
This article contributes to the research on bots in Social Media. It takes as its starting point an emerging perspective which proposes that we should abandon the investigation of the Turing Test and the functional aspects of bots in favor of studying ...

Non-linear effects on Turing patterns: time oscillations and chaos. [PDF]

open access: yes, 2012
We show that a model reaction-diffusion system with two species in a monostable regime and over a large region of parameter space, produces Turing patterns coexisting with a limit cycle which cannot be discerned from the linear analysis. As a consequence,

Myofibril and mitochondria morphogenesis are coordinated by a mechanical feedback mechanism in muscle

open access: yesNature Communications, 2021
Mitochondria produce high amounts of ATP to power myosin motors and sustained muscle contraction. Here, the authors show that during development, muscles coordinate the morphogenesis of their myofibrils directly with their mitochondria to optimize both ...

Turing-Hopf patterns in a morphochemical model for electrodeposition with cross-diffusion

open access: yesApplications in Engineering Science, 2021
This paper focuses on the impact of cross-diffusion for Turing-Hopf instability in a morphochemical model for electrodeposition (DIB) and completes the analysis on the role of cross-diffusion on pattern formation in electrodeposition we recently carried ...

Convective Turing patterns

open access: yesPhysical Review Letters, 1993
Turing patterns involve regions of different chemical compositions which lead to density gradients that, in liquids, are potentially unstable hydrodynamically. Nonlinear hydrodynamics coupled with a model of Turing pattern formation show that convection modifies and coexists with some Turing patterns and excludes others, and thereby plays a significant

Reactive Turing machines [PDF]

open access: yesInformation and Computation, 2011
We propose reactive Turing machines (RTMs), extending classical Turing machines with a process-theoretical notion of interaction, and use it to define a notion of executable transition system. We show that every computable transition system with a bounded branching degree is simulated modulo divergence-preserving branching bisimilarity by an RTM, and ...

Verifying Time Complexity of Deterministic Turing Machines [PDF]

open access: yes, 2014
We show that, for all reasonable functions $T(n)=o(n\log n)$, we can algorithmically verify whether a given one-tape Turing machine runs in time at most $T(n)$. This is a tight bound on the order of growth for the function $T$ because we prove that, for $

Assessing Simulations of Imperial Dynamics and Conflict in the Ancient World

open access: yesCliodynamics, 2019
The development of models to capture large-scale dynamics in human history is one of the core contributions of cliodynamics. Most often, these models are assessed by their predictive capability on some macro-scale and aggregated measure and compared to ...

Serotonin signaling regulates actomyosin contractility during morphogenesis in evolutionarily divergent lineages

open access: yesNature Communications, 2023
Serotonin is a neurotransmitter that signals through 5-HT receptors to control key functions in the nervous system. Serotonin receptors are also ubiquitously expressed in various organs and have been detected in embryos of different organisms.
