Effects of sauna bath on heart failure : A systematic review and meta-analysis
2018
Background: Sauna bath has potential as a lifestyle treatment modality for heart failure (HF). It is important to analyze the current evidence to help suggest paths of future study and potential for clinical application. Hypothesis: Sauna bath has a positive effect on HF patients. Methods: PubMed, Cochrane Library, and CINAHL databases were searched to identify randomized and nonrandomized controlled studies to compare effects of sauna bath with no sauna bath. Studies were searched for both infrared sauna bath and Finnish sauna bath. The strength of evidence was rated using a modified GRADE approach. Out of 1444 studies, nine met the inclusion criteria and were included in this review. Seve…

Rap-imago rap-artisti Cheekin lyriikoissa
2014
Rap-musiikki on noussut muutaman viimeksi kuluneen vuoden aikana hyvin suosituksi Suomessa. Yksi suosituimmista ja tunnetuimmista rap-artisteista on artistinimeä Cheek käyttävä Jare Tiihonen. Cheek on julkaissut musiikkia yli kymmenen vuoden ajan ja hänen tuotantonsa on pääosin suomenkielistä. Cheekin tekstejä on jonkin verran tarkasteltu kielitieteellisissä tutkimuksissa, muttei imagonrakentamisen näkökulmasta. Yleisesti ottaen suomirapia on tutkittu toistaiseksi vähän. Tutkimuksessani tarkastelin Cheekin lyriikoissaan rakentamaa imagoa. Tutkimuskysymysteni pohjalta selvitin, minkälaisin kielellisin keinoin Cheek rakentaa imagoaan, minkälainen tämä rakentuva imago on ja kuinka kielen keino…
Approximating hidden chaotic attractors via parameter switching.
2018
In this paper, the problem of approximating hidden chaotic attractors of a general class of nonlinear systems is investigated. The parameter switching (PS) algorithm is utilized, which switches the control parameter within a given set of values with the initial value problem numerically solved. The PS-generated attractor approximates the attractor obtained by averaging the control parameter with the switched values, which represents the hidden chaotic attractor. The hidden chaotic attractors of a generalized Lorenz system and the Rabinovich-Fabrikant system are simulated for illustration. In Refs. 1–3, it is proved that the attractors of a chaotic system, considered as the unique numerical …
Claude Debussyn pianomusiikki : näkökulmana kuulijan mielikuvat ja teosten kuvailevat otsikot
2014
Musiikki on yksi kommunikaation keino, jonka avulla voidaan välittää viestejä ja merkityksiä kuulijalle. Musiikin kuulijassa herättämät mielikuvat ovat osa musiikillista kommunikaatiota, jossa säveltäjän ilmaisemat asiat välittyvät teoksen avulla kuulijalle. Musiikista puhuttaessa käytetään yleisesti metaforisia mielikuvia, jotka antavat musiikilliseen kokemukseen erilaisen näkökulman kuin analyyttiset kuvaukset. Tässä tutkimuksessa tarkasteltiin, millaisia mielikuvia Claude Debussyn pianomusiikki herättää kuulijoissa, ja onko niillä yhteyttä kappaleiden alkuperäisiin otsikoihin, jotka ovat säveltäjän itsensä antamia. Lisäksi tarkasteltiin musiikkianalyysin avulla sitä, onko kappaleiden nuo…
Noticing-prefaced recoveries of the interactional space in a video-mediated business meeting
2020
Drawing on conversation analysis and authentic data from a video-mediated multiparty meeting, this study investigates the sequential and temporal organisation of recoveries of the interactional space. It focuses on moments in which either an auditory or a visual barrier emerges, and the participants orient to these troubles through intensified bodily-visual displays: embodied noticings. The analysis illustrates noticing-prefaced recoveries of the interactional space as procedural and multimodal accomplishments that require close attentiveness to the co-participants’ verbal and visual conduct and to the contingencies of the meeting. The study highlights not only the affordances of video-medi…
Oppilaiden kaikupuheen tehtävät kielellisesti epäsymmetrisissä luokkahuonekeskusteluissa
2017
Repeating the words of the conversational partners gives the persons with restricted communicative abilities a possibility for taking an active part in and exerting some control in the conversational interaction. Earlier research has approached the repeats with two different viewpoints: they have been considered either as problematic and meaningless echolalia, or as motivated communication meaningful for speakers themselves. This paper examines the functions for which students with special needs use repetition in their interaction with teachers and the ways in which teachers treat these echolalic responses in classroom talk. The research data consists of the video-recordings of lessons in o…
Approximation of functions over manifolds : A Moving Least-Squares approach
2021
We present an algorithm for approximating a function defined over a $d$-dimensional manifold utilizing only noisy function values at locations sampled from the manifold with noise. To produce the approximation we do not require any knowledge regarding the manifold other than its dimension $d$. We use the Manifold Moving Least-Squares approach of (Sober and Levin 2016) to reconstruct the atlas of charts and the approximation is built on-top of those charts. The resulting approximant is shown to be a function defined over a neighborhood of a manifold, approximating the originally sampled manifold. In other words, given a new point, located near the manifold, the approximation can be evaluated…
Adaptive Service Offloading for Revenue Maximization in Mobile Edge Computing With Delay-Constraint
2019
Mobile Edge Computing (MEC) is an important and effective platform to offload the computational services of modern mobile applications, and has gained tremendous attention from various research communities. For delay and resource constrained mobile devices, the important issues include: 1) minimization of the service latency; 2) optimal revenue maximization; 3) high quality-of-service (QoS) requirement to offload the computational service offloading. To address the above issues, an adaptive service offloading scheme is designed to provide the maximum revenue and service utilization to MEC. Unlike most of the existing works, we consider both the delay-tolerant and delay-constraint services i…
Pain fingerprinting using multimodal sensing: pilot study
2021
Abstract Pain is a complex phenomenon, the experience of which varies widely across individuals. At worst, chronic pain can lead to anxiety and depression. Cost-effective strategies are urgently needed to improve the treatment of pain, and thus we propose a novel home-based pain measurement system for the longitudinal monitoring of pain experience and variation in different patients with chronic low back pain. The autonomous nervous system and audio-visual features are analyzed from heart rate signals, voice characteristics and facial expressions using a unique measurement protocol. Self-reporting is utilized for the follow-up of changes in pain intensity, induced by well-designed physical …
