A myoelectric control system for prostheses was developed and evaluated on six healthy subjects. These were able to control a computer-animated hand in real-time with a 20 Hz update rate. A data glove, equipped with joint angle sensors, was used to train the system and to evaluate the continuous predictions of joint angles. A linear envelop filter was used for EMG signal pre-processing and the rec
An isochromosome of the long arm of chromosome 17, i(17q), is the most frequent genetic abnormality observed during the disease progression of Philadelphia chromosome-positive chronic myeloid leukemia (CML), and has been described as the sole anomaly in various other hematologic malignancies. The i(17q) hence plays a presumably important pathogenetic role both in leukemia development and progressi
Channels were activated, in ripped-off patches from rat-cultured hippocampal neurons, by propofol alone, propofol plus 0.5 muM GABA (gamma-aminobutyric acid) or GABA alone. The propofol-activated currents were chloride-selective, showed outward-rectification and were enhanced by 1 muM diazepam. The maximum propofol-activated channel conductance increased with propofol concentration from less than
Dynamic changes in absolute residual PME activity in potato tubers undergoing blanching were analysed with regard to the temperature distribution in the tissue after the treatment. The finite-element technique was used to predict the temperature distribution within the tissue during blanching. The temperature-related behaviour of the enzyme indicated that blanching between 60 and 70 degreesC induc
Popular Abstract in Swedish Gummi är inte enbart olinjärt elastiskt, det är också beroende av töjningshastighet och töjningsamplitud. Kombinationen av de olinjära elastiska egenskaperna och amplitudberoendet behandlas av de modeller som föreslås i avhandlingen. Modellerna är utformade så att de snabbt ska kunna implementeras i industrin.Rubber is not only a non-linear elastic material, it is also dependent on strain rate, temperature and strain amplitude. The non-linear elastic property and the strain amplitude dependence give a non-linear dynamic behavior that is covered by the models suggested in this thesis. The focus is on a finite element procedure for modelling these dynamic properties of rubber in a way that is easy to ado
Popular Abstract in Swedish Reumatoid artrit/ledgångsreumatism (RA) är en kronisk inflammatorisk sjukdom som i första hand drabbar lederna. Man uppskattar sjukdomens förekomst i den vuxna befolkningen till cirka en halv procent och den är 2-4 gånger vanligare hos kvinnor. Vi vet inte vad som orsakar RA, men såväl ärftliga som omgivningsfaktorer har betydelse. RA har ett varierande förlopp. Dels kaRheumatoid arthritis (RA) is characterized by persistent inflammation, progressive joint damage and disability. This thesis describes the outcome after 10 years in a cohort of 183 RA patients (116 women, 67 men) recruited 1985-89. The mean age was 51 years and symptom duration 11 months at inclusion. Standardized clinical, biochemical and radiographic assessments were performed annually. Health st
In this essay, I discuss two major theoretical discourses of modernity, namely, of classical modernity and postmodernity. Moreover, I aim at a proposition of a possible historical relation between those two discourses of crucial importance to modernity’s intellectual history. This historical connection is founded on what I call the principle of insufficient reason. The principle of insufficient
The neighborhood of Sant-Henri in Montréal’s Southwest borough has long been associated with poverty, marginality and squalor. But this is rapidly changing as both extraordinary, large-scale green infrastructures and small-scale, more ordinary forms of greening are expanding across the neighborhood, amidst private luxury housing development and rising rents. Both extraordinary and ordinary greenin
The multifunctionality of forest systems calls for appropriately complex modelling approaches to capture social and ecosystem dynamics. Using a social-ecological systems framework, we review the functionality of 31 existing agent-based models applied to managed forests. Several applications include advanced cognitive and emotional decision-making, crucial for understanding complex sustainability c
Importance: Despite the large health burden, reliable data on sepsis epidemiology are lacking; studies using International Statistical Classification of Diseases and Related Health Problems (ICD)-coded hospital discharge diagnosis for sepsis identification suffer from limited sensitivity. Also, ICD data do not allow investigation of underlying pathogens and antimicrobial resistance. Objectives: To
Learning outcomes: This case study covers different concepts related to leadership. It should help students analyze business situations from a leader’s perspective. By the end of this case study, students would be able to understand the role and the characteristics of leadership during a crisis using the 11 dimensions of character framework, map leadership personalities using the HEXACO model to u
The 2030 Agenda of the United Nations comprises 17 Sustainable Development Goals (SDGs) and 169 sub-targets which serve as a global reference point for the transition to sustainability. The agenda acknowledges that different issues such as poverty, hunger, health, education, gender equality, environmental degradation, among others, are intertwined and can therefore only be addressed together. Impl
Mitochondria are central organelles in the homeostasis of the cardiovascular system via the integration of several physiological processes, such as ATP generation via oxidative phosphorylation, synthesis/exchange of metabolites, calcium sequestration, reactive oxygen species (ROS) production/buffering and control of cellular survival/death. Mitochondrial impairment has been widely recognized as a
The complex interplay of the tumour and immune cells affects tumour growth, progression, and response to treatment. Restorationof effective immune response forms the basis of onco-immunology, which further enabled the development of immunotherapy. Inthe era of precision medicine, pin-pointing patient biological heterogeneity especially in relation to patient-specific immunemicroenvironment is a ne
Reinforcement learning with sparse rewards is still an open challenge. Classic methods rely on getting feedback via extrinsic rewards to train the agent, and in situations where this occurs very rarely the agent learns slowly or cannot learn at all. Similarly, if the agent receives also rewards that create suboptimal modes of the objective function, it will likely prematurely stop exploring. More
Popular Abstract in Swedish Färger innehåller mer tillförlitlig information än vad bara skillnader i ljusintensitet gör. Det är därför inte svårt att förstå varför de allra flesta landlevande ryggradsdjur har färgseende. Några upplever en färgfattigare värld än vi människor, men många ser fler färgnyanser. På kvällen däremot gör bristen på ljus det svårt att se färger. Trots detta finns det nattakMost terrestrial vertebrates have colour vision, some perceive a less colourful world and others actually discriminate a wider colour spectrum than humans do. Still, we can all make use of the valuable colour information, which is more rigid than just brightness. However, at night when the light is dim, the lack of photons makes colour vision difficult. Nevertheless, some hawkmoths and bees can se
I denna uppsats utreds och analyseras hur rättsväsendet hanterar hatbrott begångna på internet. År 2013 rapporterade Brottsförebyggande rådet att personuppklarningen vad gäller hatbrott begångna på internet är mycket låg. Följaktligen fortsätter uppsatsen med att identifiera orsakerna till den låga personuppklarningen samt de brister rättsväsendet besitter på området. I avslutande del av uppsatsenThis paper is set out to investigate and analyze how the judicial system handles hate crime committed on the internet. In 2013 the Swedish national council of crime prevention (Brå) reported that the clearance rate in terms of hate crime committed on the internet is very low. Hence the paper continues with identifying the causes of the low clearance rate and the shortcomings the judicial system po
The purpose of this study was to investigate the relation between alexithymia, exhaustion syndrome and well-being. The examination was designed as a crosssectional study in which the measures TAS-20, KEDS and BBQ was administered by a survey online. A total of 557 participants were recruited. The results showed that higher degree of alexithymia was connected to more severe symptoms of exhaustion s
A Power Amplifier (PA) is an essential electronic component in all microwave and millimeter-wave applications and, more specifically, in any transmitting system where the level of input power signal needs amplification to the desired level.Linearity and high efficiency are of utmost importance in PAs. However, high-efficiency PAs tend to be non-linear, and PAs working in the linear region might ha
