Cardiac cycle and respiration phase affect responses to the conditioned stimulus in young adults trained in trace eyeblink conditioning
2022
Rhythms of breathing and heartbeat are linked to each other as well as to rhythms of the brain. Our recent studies suggest that presenting the conditioned stimulus during expiration or during the diastolic phase of the cardiac cycle facilitates neural processing of that stimulus and improves learning an eyeblink classical conditioning task. To date, it has not been examined whether utilizing information from both respiration and cardiac cycle phases simultaneously allows even more efficient modulation of learning. Here we studied whether the timing of the conditioned stimulus to different cardiorespiratory rhythm phase combinations affects learning trace eyeblink conditioning in healthy you…
Saddle index properties, singular topology, and its relation to thermodynamic singularities for aϕ4mean-field model
2004
We investigate the potential energy surface of a ${\ensuremath{\phi}}^{4}$ model with infinite range interactions. All stationary points can be uniquely characterized by three real numbers ${\ensuremath{\alpha}}_{+},{\ensuremath{\alpha}}_{0},{\ensuremath{\alpha}}_{\ensuremath{-}}$ with ${\ensuremath{\alpha}}_{+}+{\ensuremath{\alpha}}_{0}+{\ensuremath{\alpha}}_{\ensuremath{-}}=1$, provided that the interaction strength $\ensuremath{\mu}$ is smaller than a critical value. The saddle index ${n}_{s}$ is equal to ${\ensuremath{\alpha}}_{0}$ and its distribution function has a maximum at ${n}_{s}^{\mathrm{max}}=1∕3$. The density $p(e)$ of stationary points with energy per particle $e$, as well as…
Thermodynamics: Classical Framework
2016
This chapter starts with a summary of the thermodynamic potentials and the relationships between them which are obtained from Legendre transformation. This is followed by an excursion to some important global properties of materials such as specific heat, expansion coefficients and others. The thermodynamic relations provide the basis for a discussion of continuous changes of state which are illustrated by the Joule-Thomson effect and the Van der Waals gas. These are models which are more realistic than the ideal gas. The discussion of Carnot cycles leads to and illustrates the second and third laws of thermodynamics. The chapter closes with a discussion of entropy as a concave function of …
Constant inner potential DFT for modelling electrochemical systems under constant potential and bias
2021
Electrochemical interfaces and reactions play a decisive role in e.g. clean energy conversion but understanding their complex chemistry remains an outstanding challenge. Constant potential or grand canonical ensemble (GCE) simulations are indispensable for unraveling the properties of electrochemical processes as a function of the electrode potential. Currently, constant electrode potential calculations at the density functional theory (DFT) level are carried out by fixing the Fermi level of the simulation cell. However, the Fermi level from DFT calculations does does not always reflect the experimentally controlled electrode potential or describe the thermodynamic independent variable in G…
Bounds for Bessel functions
1989
We establish lower and upper bounds for the Bessel functionJ v (x) and the modified Bessel functionI v(x) of the first kind. Our chief tool is the differential equation satisfied by these functions.
"Osaatteko te uusavuttomat urvelot siellä yhtään mitään?" : Onnibussin Facebook-sivulla esiintyvien asiakaspalautteiden rakennepotentiaali
2018
Tässä tutkielmassa tarkastelen Onnibussin Facebook-sivuilla esiintyvien asiakaspalautteiden rakennetta muodostaen sille oman rakennepotentiaalimallin. Tutkimus on ajankohtainen, sillä asiakaspalautteita sosiaalisen median kontekstissa ei ole aiemmin tutkittu suomen kielen alalla. Tämä tutkielma antaa myös suuntaviivoja kysymykselle siitä, poikkeaako sosiaalisessa mediassa esiintyvä asiakaspalaute perinteisestä asiakaspalautteesta. Tutkimuskysymyksiäni ovat seuraavat kysymykset: 1.Mistä funktionaalisista rakenneosista asiakaspalaute koostuu? a. Mitkä rakenneosat ovat välttämättömiä? b. Mitkä rakenneosat ovat valinnaisia? c. Millaista säännönmukaisuutta rakenneosien järjestäytymisestä löytyy?…
When did biopolitics begin? : Actuality and potentiality in historical events
2022
The article addresses the ongoing debate about the origins of biopolitics. While Foucault’s analysis of biopolitics approached it as a modern rationality of government, Agamben’s Homo Sacer series presented biopolitics as having a longer provenance, dating back to the antiquity. These polar positions are not mutually exclusive but coexist in these and other theories of biopolitics, which approach its object as both modern and ancient, having its chronological origin in the eighteenth to nineteenth centuries yet also possessing a prehistory of precursors. The article interprets this dual origin in terms of Paolo Virno’s theory of historical temporality, which distinguishes between the chron…
Teoria integrata del crimine dei potenti di Box
2021
Riflessione su: la teoria integrata del crimine dei potenti di Steven Box (1987) che presenta un modello d’integrazione concettuale «fianco a fianco», che fa riferimento alle principali teorie moderne (anomia/ tensione, legami/controllo, apprendimento sociale, neutralizzazioni, subculture, struttura di opportunità e controllo sociale). Il crimine dei potenti è spiegato come il prodotto dei tentativi che attori formali (come società, aziende, governi, multinazionali, ecc.) attuano nel raggiungimento di obiettivi specifici in contesti altrimenti incerti. Reflection on: Steven Box's (1987) integrated theory of crime of the powerful which presents a model of conceptual integration "side by side…
L'espace de liberté comme mesure synthétique du développement territorial durable
2011
By discussing the concept of development itself, authors propose two synthetic indexes relying on estimation of potential: Development Space Value and Development Space Creation Under the weak hypothesis that any successful development improves future possibilities, changes in potential are a good development measure. In their path, authors show how development space is tied with freedom: a shrink in it results mechanically in indexes fall. So, "sustainable" and "economic" become two sides of same piece rather than enemies. Reliable in simulations, the approach is to be tested in real conditions, to verify full data availability and to secure calculating methods.
