Network-based biocomputation (NBC) is an alternative, parallel computation approach that can potentially solve technologically important, combinatorial problems with much lower energy consumption than electronic processors. In NBC, a combinatorial problem is encoded into a physical, nanofabricated network. The problem is solved by biological agents (such as cytoskeletal filaments driven by molecul
Objective We aimed to determine the key predictors of perinatal deaths using machine learning models compared with the logistic regression model. Design A secondary data analysis using the Kilimanjaro Christian Medical Centre (KCMC) Medical Birth Registry cohort from 2000 to 2015. We assessed the discriminative ability of models using the area under the receiver operating characteristics curve (AU
The German Federal State of Saxony aims to increase forest cover, supported by the implementation of afforestation programs. To analyze consequences of an increase in forest cover, this study investigates possible trade-offs between carbon storage and plant biodiversity caused by afforestation. Six afforestation scenarios with total forest cover ranging from 27.7% to 46% were generated in the Muld
Objectives: The aim of this study was to explore the prevalence of eating difficulties and malnutrition among persons in hospital care and in special accommodations. Design: The cross-sectional observational study was performed in Nov. 2005. Setting: Hospitals and special accommodations. Participants: Out of 2945 persons, 2600 (88%) agreed to participate (1726 from special accommodations and 874 f
We present a study of neural network architectures able to internally simulate perceptions and actions. All these architectures employ the novel Associative Self-Organizing Map (A-SOM) as a perceptual neural network. The A-SOM develops a representation of its input space, but in addition also learns to associate its activity with an arbitrary number of additional (possibly delayed) inputs. One arc
Popular Abstract in Swedish Många forskningsprojekt inom materialvetenskap, medicin eller grundläggande fysik kräver smala strålar av laddade partiklar som fungerar som provtagare för att undersöka materiens egenskaper. Dessa partiklar kan vara protoner, elektroner lättare joner. Relativt ofta, behöver de accelereras nästan upp till ljusets hastighet för att kunna tränga in tillräckligt djupt i prLaser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the
Popular Abstract in Swedish Värmebehandling (termoterapi) av tumör baseras på kunskap om den celldödande effekten av värme. Den har begränsats av svårigheten att kontrollera temperaturutbredningen så att en selektiv och tillräcklig effekt erhålls, och detta gäller särskilt djupt belägna tumörer. Interstitiell laser termoterapi (ILT) med Nd:YAG laser är en ny behandlingsform, som ger de tekniska föInterstitial laser thermotherapy (ILT) is a method well suited for selective local destruction of malignant tumours. In the present work, a laser thermotherapy system based on feedback temperature control of energy delivery (through computerised feedback system) was developed. Temperature control was excellent in experiments without carbonization and with preserved light penetration, whereas tempe
This investigation makes a survey of the spread of fire and the fire development in low-rise residential building areas through obtaining the literal knowledge of factors having influence on a fire in one burning building and fire spread between buildings within a group of single-family houses. The purpose of the investigation was, on basis of the knowledge, to propose improved measures and the ch
This poster concerns the articulation of uvular consonants with particular reference to quantal aspects of speech production. Data from X-ray motion films are presented. Two speakers of Southern Swedish give examples of [R], and one speaker of West Greenlandic Inuit gives examples of [R] and [q]. Traditionally, uvular consonants are said to be produced by articulating the dorsum against the uvula.

Popular Abstract in Swedish I de flesta organ i människokroppen pågår en ständig förnyelse av celler för att kompensera för gamla cellers bortfall som en följd av skador och naturlig död. En ensam cell kan på egen hand kopiera allt sitt DNA och därmed all information den bär på, för att därefter dela sig och skapa en exakt identisk kopia av sig själv. Kodat i DNA finns instruktionerna för hur en oTelomeres are the end-structures of linear chromosome which are crucial for maintaining genome integrity. The telomeres prevent the DNA-repair machinery from recognizing the chromosome ends as double-strand breaks and from end-to-end fusions. The telomeres are composed by short repetitive units of TG-rich DNA and associated specialized telomere-binding proteins. Due to that replication only can
Background. To study group B streptococcus (GBS) colonisation in parturients and infants in relation to obstetric outcome and to define serotypes and antibiotic resistance in GBS isolates acquired. Methods. A population-based, national cohort of parturients and their infants was investigated. During 1 calendar week in 2005 all women giving birth (n=1,754) were requested to participate in the study
Background: Identifying individuals at high risk of excess weight gain may help targeting prevention efforts at those at risk of various metabolic diseases associated with weight gain. Our aim was to develop a risk score to identify these individuals and validate it in an external population. Methods: We used lifestyle and nutritional data from 53 degrees 758 individuals followed for a median of 5
