The performance of the linear consensus algorithm is studied by using a linear quadratic (LQ) cost. The objective is to understand how the communication topology influences this algorithm. This is achieved by exploiting the analogy between Markov chains and electrical resistive networks. Indeed, this allows us to uncover the relation between the LQ performance cost and the average effective resist
Den makaronesiska övärlden i likhet med de flesta andra ögrupper av vulkaniskt ursprung präglas ofta av en stor biologisk mångfald. En stor mångfald av arter inom många släkten och närvaro av närbesläktade arter i närliggande miljöer tyder på en utveckling av arter genom adaptiv radering. Endemismen är alltid procentuellt hög i dessa övärldar. Vill man uppleva unika endemer inom flora och även fau
Secreted protein acidic and rich in cysteine (SPARC) is a matricellular glycoprotein that has been implicated in tumor-stroma interactions in pancreatic cancer. Here we evaluated the expression of SPARC during the progression of pancreatic cancer and its correlation with survival following curative intent surgery.
Human papillomavirus (HPV) infection is a necessary factor in the cervical cancer development. Also after treatment for cervical dysplasia, HPV can be present and promote the recurrence of cervical disease. In the present study, the aim was to perform a long-term follow-up on the ability of HPV testing with genotyping, as compared with cytology, to predict recurrence of high-grade cervical intraep
Thymidine kinase 1 (TK1) provides a crucial precursor, thymidine monophosphate (dTMP), for nucleic acid synthesis, and the activity of TK1 increases up to 200-fold during the S-phase of cell division in humans. An important part of the regulatory check-points is the ATP and enzyme concentration-dependent transition of TK1 from a dimer with low catalytic efficiency to a tetramer with high catalytic
Understanding the impacts of plant community characteristics on soil carbon dioxide efflux (R) is a key prerequisite for accurate prediction of the future carbon (C) balance of terrestrial ecosystems under climate change. However, developing a mechanistic understanding of the determinants of R is complicated by the presence of multiple different sources of respiratory C within soil - such as soil
Gas turbines are widely used for aircraft propulsion, land-base power generation, and other industrial applications like trains, marines, automobiles, etc. To satisfy the fast development of advanced gas turbines, the operating temperature must be increased to improve the thermal efficiency and output work of the gas turbine engine. However, the heat transferred to the turbine blade is substantial
The article examines the underlying conceptions of the practices of creativity embedded in the global copyright construction, and argues that there is a prevailing idealized image expressed in terms of individual and autonomous performance of “solitary geniuses”. This conception is an important part of what may be called a copyright ideology that increasingly has let the law develop into an indust
Long-term survivors of childhood cancer suffer from a higher mortality than the general population. Here we evaluate late and very late mortality, and patterns of causes of death, in five year survivors after childhood and adolescent cancer in cases diagnosed during four decades in the five Nordic countries. The study is population-based and uses data of the nationwide cancer registries and the ca
The aim of this study was to visualise the dynamics and interactions of the cells involved in autoimmune-driven inflammation in type 1 diabetes. We adopted the anterior chamber of the eye (ACE) transplantation model to perform non-invasive imaging of leucocytes infiltrating the endocrine pancreas during initiation and progression of insulitis in the NOD mouse. Individual, ACE-transplanted islets o

Objective To assess the failure rate of cemented, uncemented, hybrid, and reverse hybrid total hip replacements in patients aged 55 years or older. Design Register study. Setting Nordic Arthroplasty Register Association database (combined data from Sweden, Norway, Denmark, and Finland). Participants 347 899 total hip replacements performed during 1995-2011. Main outcome measures Probability of imp
Aerococcus is a genus that comprises seven species, of which Aerococcus urinae, and Aerococcus sanguinicola are emerging human pathogens. Aerococci are gram positive cocci that are easily misidentified as streptococci or staphylococci, and thus the incidence of aerococcal infections has been underestimated. With the introduction of matrix-assisted laser desorption ionization time-of-flight mass sp
Ukraine (UA) faces broad needs for energy security enhancement, energy diversification, revitalization of agriculture, and improvements in the state of the environment. UA has large biomass-for-bioenergy potential, which can be leveraged to contribute to local/regional energy self-sufficiency, rural development and diversification, and environmental improvement via fossil fuel substitution with lo
Vascular smooth muscle cells (SMCs) display remarkable phenotypic plasticity in response to environmental cues. The nuclear factor of activated T-cells (NFAT) family of transcription factors plays a critical role in vascular pathology. However, known functional NFAT gene targets in vascular SMCs are currently limited. Publicly available whole-genome expression array data sets were analyzed to iden
As oil-prices and environmental concerns are increasing, it is of interest to better use the well-head gas. This light fraction co-produced with petroleum is generally flared and in this paper a method for upgrading and returning the co-product to the petroleum stream is suggested. The method is based on a conversion of the gas to synthesis gas and upgrading this synthesis gas into liquid hydrocar
Hos 11,8-9 is characterized by its strong anthropomorphic language and by its (illusory?) disassociation from it. A reference to Israel’s God as “not human” motivates the unexpected change of mind and compassion for God’s Israel. This article is based on a tradition-historical oriented typological reading of the expression “I am God and not human.” It suggests a new interpretation of this expressi
In contrast to most vertebrates, invertebrate deuterostome echinoderms, such as the sea star Asterias rubens, undergo regeneration of lost body parts. The current hypothesis suggests that differentiated cells are the main source for regenerating arm in sea stars, but there is little information regarding the origin and identity of these cells. Here, we show that several organs distant to the regen
Diagnostic for investigating and distinguishing different laser ion acceleration mechanisms has been developed and successfully tested. An ion separation wide angle spectrometer can simultaneously investigate three important aspects of the laser plasma interaction: (1) acquire angularly resolved energy spectra for two ion species, (2) obtain ion energy spectra for multiple species, separated accor
