The Calderón problem for the fractional Schrödinger equation

2020

We show global uniqueness in an inverse problem for the fractional Schr\"odinger equation: an unknown potential in a bounded domain is uniquely determined by exterior measurements of solutions. We also show global uniqueness in the partial data problem where the measurements are taken in arbitrary open, possibly disjoint, subsets of the exterior. The results apply in any dimension $\geq 2$ and are based on a strong approximation property of the fractional equation that extends earlier work. This special feature of the nonlocal equation renders the analysis of related inverse problems radically different from the traditional Calder\'on problem.

Protonation of Carbonate in Aqueous Tetraalkylammonium Salts at 25°C.

2006

Protonation constants of carbonate were determined in tetramethylammonium chloride (Me4NClaq 0.1≤I/mol kg−1 ≤4) and tetraethylammonium iodide (Et4NIaq 0.1≤I/mol kg−1 ≤1) by potentiometric ([H+]-glass electrode) measurements. Dependence of protonation constants on ionic strength was taken into account by modified specific ion interaction theory (SIT) and by Pitzer models. Literature data on the protonation of carbonate in NaClaq (0.1≤I/mol kg−1 ≤6) were also critically analysed. Both protonation constants of carbonate follow the trend Et4NI>Me4NCl > NaCl. An ion pair formation model designed to take into account the different protonation behaviours of carbonate in different supporting electr…

A Framework for a Smart City Design : Digital Transformation in the Helsinki Smart City

2019

Recently, there has been substantial interest in the concept of a smart city, as it has been a viable solution to the dilemmas created by the urbanization of cities. Digital technologies—such as Internet-of-Things, artificial intelligence, big data, and geospatial technologies—are closely associated with the concept of a smart city. By means of modern digital technologies, cities aim to optimize their performance and services. Further, cities actively endorse modern digital technologies to foster digitalization and the emergence of data-based innovations and a knowledge economy. In this paper, a framework for a smart city design is presented. The framework considers a smart city from the pe…

Kilpailu vaikuttaa nieriän ravintoon

2013

Lapin nieriäkannat ovat monin paikoin taantuneet uusien kalalajien levittäytymisen seurauksena. Tuore väitöskirjatutkimus osoittaa, että nieriä voi vaihtaa ravintoaan ja elinpaikkaansa vähentääkseen kilpailua muiden kalalajien kanssa. nonPeerReviewed

Student evaluations of the credibility and argumentation of online sources

2021

This study investigated upper secondary school students’ skills in evaluating the credibility and argumentative content of a blog text and a YouTube video. Both sources concerned child vaccination, the blog text opposing and the YouTube video supporting it. Students rated each source as credible, fairly credible or non-credible, justified their ratings, and analyzed the argumentation of both sources. Their justifications were analyzed for trustworthiness and expertise and their argument analyses for identification of the main position of the source and the reasons supporting it. Students’ justification skills proved fairly weak, and they also struggled with recognizing unbalanced argumentat…

Human Sociability in Antonio Montecatini's (1537–99) Commentary on Aristotle's Politics

2021

The present article delves into the history of political philosophy by discussing human sociability in Antonio Montecatini's (1537–99) commentary on Aristotle's Politics. The focus is on a philosophical analysis of three interrelated ideas that Montecatini discusses: (1) Aristotle's dictum that human beings are political animals by nature; (2) naturalness of the household; and (3) the nature and origin of political communities. Montecatini's views are briefly related to those of John Case (ca. 1546–1600), and they are also contextualized within the late medieval commentary tradition on the Politics, but the main aim is to clarify Montecatini's philosophical position and examine the ways in …

Biologinen sosiaalisen mallina. Valintoja uuden hedelmöityshoitolain kentällä.

2007

Tarkastelen artikkelissa hedelmöityshoitoja koskevan lakiprosessin aikaista kamppailua, joka realisoitui Laiksi hedelmöityshoidoista (1237/2006). Analysoin tarkemmin lain viidettä pykälää (1237/2006, 5§) sekä siitä lakiesityksessä HE 3/2006 esitettyjä perusteluja. Pykälän mukaan lääkärin tulee valita sukusolujen luovuttajista hoitoa saavan parin osapuolia muistuttavat henkilöt, sillä lapsen tulee saada muistuttaa myös sosiaalista vanhempaansa. Analysoin lain viidennen pykälän sisältämiä vanhempien ja lapsen asemaa koskevia lausumia modaalisuusanalyyttisesti käyttäen apuna semioottista neliötä. Neliön kautta ilmennän hoitoihin osallistuvien positioiden modaalista astevaihtelua, joka osoittaa…

Recent advances in machine learning for maximal oxygen uptake (VO2 max) prediction : A review

2022

Maximal oxygen uptake (VO2 max) is the maximum amount of oxygen attainable by a person during exercise. VO2 max is used in different domains including sports and medical sciences and is usually measured during an incremental treadmill or cycle ergometer test. The drawback of directly measuring VO2 max using the maximal test is that it is expensive and requires a fixed and controlled protocol. During the last decade, various machine learning models have been developed for VO2 max prediction and numerous studies have attempted to predict VO2 max using data from submaximal and non-exercise tests. This article gives an overview of the machine learning models developed over the past five years (…

The mediating role of behavioural automaticity and intention on past to future bootcamp attendance

2023

Objective The aim of the current study was to test whether behavioural automaticity and intention mediated the effects of past behaviour on a particular type of vigorous physical exercise: bootcamp attendance. Methods A community sample (N = 69) who had previously attended a bootcamp class was recruited from Queensland, Australia. Participants were asked to complete measures of their previous bootcamp attendance, behavioural automaticity, and intention to attend bootcamps (Time 1). One month later (Time 2), participants were asked to report their bootcamp attendance and behavioural automaticity in the previous month. Data were fitted to a Partial Least Squares-SEM model. Results Past behavi…
