Exploring relationships between effort, motion, and sound in new musical instruments

2020

We investigated how the action–sound relationships found in electric guitar performance can be used in the design of new instruments. Thirty-one trained guitarists performed a set of basic sound-producing actions (impulsive, sustained, and iterative) and free improvisations on an electric guitar. We performed a statistical analysis of the muscle activation data (EMG) and audio recordings from the experiment. Then we trained a long short-term memory network with nine different configurations to map EMG signal to sound. We found that the preliminary models were able to predict audio energy features of free improvisations on the guitar, based on the dataset of raw EMG from the basic soundprodu…

Hapenkulutuksen ja reiden lihasaktiivisuuden välinen yhteys pyöräilyssä

2002

Pollari, Terhi. Hapenkulutuksen ja reiden lihasaktiivisuuden välinen yhteys pyöräilyssä. LFY.203 Johdatus omatoimiseen tutkimustyöhön —kurssin tutkielma. Liikuntabiologian laitos. Jyväskylän yliopisto. Hapenkulutuksen kasvun tietyssä harjoituksessa on monesti oletettu olevan yhteydessä lisääntyneeseen lihasaktiivisuuteen työskentelevissä lihaksissa. Vaikka täysin selvää näyttöä ei ole, uskotaan hapenkulutuksen kasvun johtuvan lisääntyneestä motoristen yksiköiden käyttöönotosta tai syttymistiheydestä tehokkaan harjoituksen aikana. Hapenkulutusta ja lihasaktiivisuutta on tutkittu polkupyöräilyssä kuormilla, jotka ovat laktaattikynnystason kummallakin puolella. Tiettävästi pyöräilyssä ei kuite…

Innate immunity but not NLRP3 inflammasome activation correlates with severity of stable COPD.

2014

Background In models of COPD, environmental stressors induce innate immune responses, inflammasome activation and inflammation. However, the interaction between these responses and their role in driving pulmonary inflammation in stable COPD is unknown. Objectives To investigate the activation of innate immunity and inflammasome pathways in the bronchial mucosa and bronchoalveolar lavage (BAL) of patients with stable COPD of different severity and control healthy smokers and non-smokers. Methods Innate immune mediators (interleukin (IL)-6, IL-7, IL-10, IL-27, IL-37, thymic stromal lymphopoietin (TSLP), interferon γ and their receptors, STAT1 and pSTAT1) and inflammasome components (NLRP3, NA…

Novel Munc13-4 mutations in children and young adult patients with haemophagocytic lymphohistiocytosis

2006

Familial haemophagocytic lymphohistiocytosis (FHL) is a genetically heterogeneous disorder characterised by constitutive defects in cellular cytotoxicity resulting in fever, hepatosplenomegaly and cytopenia, and the outcome is fatal unless treated by chemoimmunotherapy followed by haematopoietic stem‐cell transplantation. Since 1999, mutations in the perforin gene giving rise to this disease have been identified; however, these account only for 40% of cases. Lack of a genetic marker hampers the diagnosis, suitability for transplantation, selection of familial donors, identification of carriers, genetic counselling and prenatal diagnosis. Mutations in the Munc13–4 gene have recently been des…

Post-fire practices benefits on vegetation recovery and soil conservation in a Mediterranean area

2021

Financiado para publicación en acceso aberto: Universidade da Coruña/CISUG. [Abstract] Post-fire practices (PFP) aim to reduce soil erosion and favour vegetation recovery, but their effectiveness is spatially heterogeneous and under debate because of the economic and environmental costs. This study evaluates the different changes (Δ) of canopy cover (CC), sediment connectivity (SC) and local topography in four areas affected by the Pinet fire in eastern Spain (August 8th, 2018) and managed with: totally burnt with tree removal and long log erosion barriers (LEBs) (Pinet-1), partially burnt without PFP (Pinet-2), totally burnt with tree removal and short LEBs (Pinet-3), and totally burnt wit…

Evaluation of the LSA-SAF gross primary production product derived from SEVIRI/MSG data (MGPP)

2020

The objective of this study is to describe a completely new 10-day gross primary production (GPP) product (MGPP LSA-411) based on data from the geostationary SEVIRI/MSG satellite within the LSA SAF (Land Surface Analysis SAF) as part of the SAF (Satellite Application Facility) network of EUMETSAT. The methodology relies on the Monteith approach. It considers that GPP is proportional to the absorbed photosynthetically active radiation APAR and the proportionality factor is known as the light use efficiency ε. A parameterization of this factor is proposed as the product of a εmax, corresponding to the canopy functioning under optimal conditions, and a coefficient quantifying the reduction of …
