Perception is not a passive process but the result of an interaction between an organism and the environment. This is especially clear in haptic perception that depends entirely on tactile exploration of an object. We investigate this idea in a system-level brain model of somatosensory and motor cortex and show how it can use signals from a humanoid robot to categorize different object. The model
Background: Fungicides are frequently used in agriculture and can enter freshwater ecosystems through multiple pathways. The negative impacts of fungicides on microorganisms, fungi in particular, and their functions such as leaf decomposition have been repeatedly shown. In our previous microcosm experiment with three consecutive cycles of fungicide exposure and colonisation of leaf substrate, we f
De politiska partiernas analyser av valet för ett år sedan lider alla av samma fel: de är för kortsiktiga. För att tolka valutslaget behövs ett långsiktigt och demografiskt perspektiv. Då hamnar fokus oundvikligen på 1940-talets baby boomers. Vi som föddes under 1940-talet har utgjort den centrala marginalväljargruppen under hela vårt vuxna liv. I ett extremt proportionellt valsystem som det svens
Phytoplankton have short generation times, flexible reproduction strategies, large population sizes and high standing genetic diversity, traits that should facilitate rapid evolution under directional selection. We quantified local adaptation of copper tolerance in a population of the diatom Skeletonema marinoi from a mining-exposed inlet in the Baltic Sea and in a non-exposed population 100 km aw
CC-GLPDC codes are a class of generalized low-density parity-check (GLDPC) codes where the constraint nodes (CNs) represent convolutional codes. This allows for efficient decoding in the trellis with the forward-backward algorithm, and the strength of the component codes easily can be controlled by the encoder memory without changing the graph structure. In this letter, we extend the class of CC-G
Single-ion magnets (SIMs) constitute the ultimate size limit in the quest for miniaturizing magnetic materials. Several bottlenecks currently hindering breakthroughs in quantum information and communication technologies could be alleviated by new generations of SIMs displaying multifunctionality. Here, ultrafast optical absorption spectroscopy and X-ray emission spectroscopy are employed to track
Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma frequently co-exist and share pathologic features. Taking a “global” treatment approach benefits diagnosis and treatment of both, but care is often siloed by specialty: joined-up clinics are uncommon. Our objectives were to explore expert opinion to give practical suggestions to identify adults needing global airways care; en
Recently, to reach zero emission levels, some new energy systems based on fuel cells have been developed. This paper presents a review of investigations of these systems by thermodynamics performance, mainly, energy and exergy analysis. With energy analysis, the performance of an energy conversion system cannot be effectively and accurately evaluated. But exergy analysis complements and reinforces
Purpose: The relative roles of urinary sphincter damage, aging, and childbirth in stress urinary incontinence (SUI), have not been established. This study was performed to elucidate the roles of these factors. Methods: The study included: (1) 8 female cynomolgus monkeys (17–19 years of age and 7–8 vaginal births each); (2) six 5-year-old nulliparous monkeys with surgically created chronic urinary
Structural Health Monitoring (SHM) can provide valuable information for maintenance-related activities and post-disaster emergency management. However, as with any technological system, SHM systems can be susceptible to errors due to malfunctioning. Therefore, it is essential to assess the potential for malfunctions and the associated costs of maintenance and repair when evaluating the long-term b
Denna avhandling undersöker hur mer jämlika och inkluderande livsmiljöer kan uppnås genom att använda Universal Utformning (UU) för att införliva mänsklig mångfald i alla stadier av planering och byggande. Det pågående utanförskapet av personer med funktionsnedsättning från den byggda miljön beror inte på bristande kunskap om hur man kan åtgärda befintliga hinder eller om hur man undviker att skapThis thesis explores how more equal and inclusive living environments can be achieved by using Universal Design (UD) to incorporate human diversity in all stages of planning and construction. The ongoing exclusion of persons with disabilities from the built environment does not result from a lack of knowledge on how to remedy existing obstacles nor of how to avoid creating new ones. Other reasons
Background: Differential diagnosis of rhabdomyosarcoma (RMS) is challenging. Sineoculis homeobox homolog 1 (SIX1) is an oncogene involved in skeletal muscle differentiation. We compared protein expression patterns of SIX1 in RMS and its most common differential diagnoses. Methods: SIX1 immunohistochemistry in 36 RMS and in 33 tumors from seven differential diagnostic subtypes were evaluated. The f
