Cost minimization of network services with buffer and end-to-end deadline constraints

Cloud computing technology provides the means to share physical resources among multiple users and data center ten- ants by exposing them as virtual resources. There is a strong industrial drive to use similar technology and concepts to provide timing sensitive services. One such is virtual net- working services, so called services chains, which consist of several interconnected virtual network fu

How Colleagues Can Support Each Other’s Needs and Motivation : An Intervention on Employee Work Motivation

Organisations have flattened and increasingly rely on teamwork. Therefore, colleagues play an increasingly important role in stimulating employee motivation. Adopting Self-Determination Theory as a guiding framework, the aim of this field experiment was to examine whether team members can be trained in supporting each other's basic psychological needs for autonomy, competence, and relatedness and,

S100β after coronary artery surgery : Release pattern, source of contamination, and relation to neuropsychological outcome

Background. S100β has been suggested as a marker of brain damage after cardiac operation. The aim of this study was to characterize the early S100β release in detail and relate it to neuropsychological outcome. Methods. Three groups of patients were investigated. All patients underwent coronary artery bypass surgery (CABG) with extracorporeal circulation. In group A, 110 patients had sampling of S

Significance of serum S100 release after coronary artery bypass grafting

Background. S100 protein has been suggested to be a serum marker for cerebral complications after cardiac operation and extracorporeal circulation. The aim of this study was to characterize the S100 release pattern after extracorporeal circulation in 515 consecutive patients undergoing coronary artery bypass grafting. Methods. Clinical variables and outcome were prospectively registered. The cereb

Thaw pond development and initial vegetation succession in experimental plots at a Siberian lowland tundra site

Permafrost degradation has the potential to change the Arctic tundra landscape. We observed rapid local thawing of ice-rich permafrost resulting in thaw pond formation, which was triggered by removal of the shrub cover in a field experiment. This study aimed to examine the rate of permafrost thaw and the initial vegetation succession after the permafrost collapse. Methods In the experiment, we mea

p53 maintains baseline expression of multiple tumor suppressor genes

TP53 is the most commonly mutated tumor suppressor gene and its mutation drives tumorigenesis. Using ChIP-seq for p53 in the absence of acute cell stress, we found that wild-type but not mutant p53 binds and activates numerous tumor suppressor genes, including PTEN, STK11(LKB1), miR-34a, KDM6A(UTX), FOXO1, PHLDA3, and TNFRSF10B through consensus binding sites in enhancers and promoters. Depletion

Care professional's experiences about using Liverpool Care Pathway in end-of-life care in residential care homes

Background: Residential care homes (RCHs) play an important role in end-of-life care, being the most common place of death for elderly people in several European countries. Care pathways such as the Liverpool Care Pathway for the Dying Patient (LCP) are used to improve and ensure quality care at the end of life. There is a lack of scientific evidence supporting the use of care pathways. Design: A

S100 protein - A marker of brain injury. The release in CABG patients without neurological complications

S100 protein, normally not found in serum, is increased after cerebral injury and is also released during ECC. Patients with neurological complications following cardiac surgery have residual concentrations due to a prolonged release from cellular injury. The aim of the present study was to characterize the S100 release that occurs after CABG in a "normal" population without clinical brain dysfunc

S100 protein, an early and prognostic serum marker for brain damage following cardiac surgery

S100 protein is a marker for brain damage easily analysed in blood. The serum level immediatly after termination of extracorporeal circulation (ECC) is increased and associated to age and the duration of perfusion. A prolonged residual concentration indicates cellular brain damage. The objective of this study was to ascertain if the prognosis of individual patients, with stroke following ECC, coul

Variation in maturity-onset diabetes of the young genes influence response to interventions for diabetes prevention

Context: Variation in genes that cause maturity-onset diabetes of the young (MODY) has been associated with diabetes incidence and glycemic traits. Objectives: This study aimed to determine whether genetic variation in MODY genes leads to differential responses to insulin-sensitizing interventions. Design and Setting: This was a secondary analysis of a multicenter, randomized clinical trial, the D

Neonatal alloimmune thrombocytopaenia associated with maternal HLA antibodies

Neonatal alloimmune thrombocytopaenia (NAIT) generally results from platelet opsonisation by maternal antibodies against fetal platelet antigens inherited from the infant's father. Newborn monochorionic twins presented with petechial haemorrhages at 10 hours of life, along with severe thrombocytopaenia. Despite the initial treatment with platelet transfusions and intravenous immunoglobulin, they b

En domstolspedagogisk ansats

En domstolspedagogisk ansats Wittgensteins (1953) privatspråksargument utmanar förståelsen vad det innebär att korrekt följa regler. Paradoxen är att det inte verkar finnas någon möjlighet att logiskt hävda att en förklaring av en regel kan binda framtida tillämpningar. Argumentet utmanar regelförståelsen. Enligt Wittgenstein är regelföljande en praxis och inget som utgår från tolkningar. Kripke (

Nonandrogenic anabolic hormones predict risk of frailty : European male ageing study prospective data

Context: Low levels of nonandrogenic anabolic hormones have been linked with frailty, but evidence is conflicting and prospective data are largely lacking. Objective: To determine associations between nonandrogenic anabolic hormones and prospective changes in frailty status. Design/Setting: A 4.3-year prospective observational study of community-dwelling men participating in the European Male Agei

Female exposure to phthalates and time to pregnancy : A first pregnancy planner study

STUDY QUESTION Is female exposure to phthalate metabolites associated with reduced fecundity, as estimated by prolonged time to pregnancy (TTP)? SUMMARY ANSWER Female exposure to monoethyl phthalate (MEP) but not monobutyl phthalate (MBP), monobenzyl phthalate (MBzP) and monoethylhexyl phthalate (MEHP) was associated with a longer TTP. WHAT IS KNOWN ALREADY Male exposure to phthalates is potential

Acquisition, maintenance and adaptation of invasion inhibitory antibodies against Plasmodium falciparum invasion ligands involved in immune evasion

Erythrocyte-binding antigens (EBAs) and P. falciparum reticulocyte-binding homologue proteins (PfRhs) are two important protein families that can vary in expression and utilization by P. falciparum to evade inhibitory antibodies. We evaluated antibodies at repeated time-points among individuals living in an endemic region in Nigeria over almost one year against these vaccine candidates. Antibody l
