We demonstrate a process to vary the gate-length of vertical MOSFETs on the same sample with high accuracy and high performance. Fabricated vertical InAs/InGaAs MOSFETs on Si have gate length ranging from 25 nm to 140 nm. The results shown are from single nanowire transistors as well as arrays with nanowires ranging from 80 to 500 nanowires. The devices show good yield and clear scaling trends. We
III-V nanowires have tunable dimensions, between 40 nm and 100 nm in diameter and between 1 and 15 μm in length. Due to their small diameter, they are ideal candidates to interact with cells without detrimental effects on the cell viability. Nanowires can be used as sensors: in our case, we have shown that arrays of vertical gallium phosphide nanowires are promising materials for biosensing in mem
Objective: To evaluate urinary tract and bowel function in children with sacrococcygeal teratoma, compare the findings with healthy children, and assess predictors of poor outcome. Study design: This was a controlled cohort study of all patients operated for sacrococcygeal teratoma at a tertiary pediatric surgery center, 2000-2013. Urinary and bowel function were compared with healthy control pati
Bone Scan Index (BSI) is a validated imaging biomarker to objectively assess tumour burden in bone in patients with prostate cancer, and can be used to monitor treatment response. It is not known if BSI is significantly altered when images are acquired at a time difference of 1 h. The aim of this study was to investigate if automatic calculation of BSI is affected when images are acquired 1 hour a
Background: Studies on sensitization to metals in the general population are scarce. Objectives: To determine the prevalence of sensitization to metals in the general population, and factors associated with nickel sensitization. Methods: In 5 European countries (The Netherlands, Germany, Italy, Portugal and Sweden), a random sample (N =3119) from the general population (aged 18-74years) was patch
Objective: Status epilepticus (SE) is an abnormally prolonged epileptic seizure that if associated with convulsive motor symptoms is potentially life threatening for a patient. However, 20%-40% of patients with SE lack convulsive events and instead present with more subtle semiology such as altered consciousness and less motor activity. Today, there is no general consensus regarding to what extent
Cohousing has caught the attention of activists, academics and decision-makers, and Danish experiences with cohousing as bofællesskaber are routinely highlighted as pioneering and successful. This article presents a mainly quantitative analysis of the development of Danish intergenerational cohousing and investigates socio-economic characteristics of residents in these communities. First, the arti
BACKGROUND: Comparable estimates of health spending are crucial for the assessment of health systems and to optimally deploy health resources. The methods used to track health spending continue to evolve, but little is known about the distribution of spending across diseases. We developed improved estimates of health spending by source, including development assistance for health, and, for the fir
BACKGROUND: Achieving universal health coverage (UHC) requires health financing systems that provide prepaid pooled resources for key health services without placing undue financial stress on households. Understanding current and future trajectories of health financing is vital for progress towards UHC. We used historical health financing data for 188 countries from 1995 to 2015 to estimate future
Background: The frequency of allergic contact dermatitis caused by (meth)acrylates is increasing worldwide, and isobornyl acrylate (IBOA) has been identified as a culprit sensitizer in FreeStyle Libre, a medical device used by diabetic patients. Objectives: To report on 4 patients sensitized to IBOA contained in OmniPod, a new, tubeless insulin pump, and to describe the clinical and chemical analy
Background: The diagnosis of chronic obstructive pulmonary disease (COPD) is often based on spirometry, which is not sensitive to early emphysema. We have recently described a method for assessing distal airspace dimensions by measuring recovery of nanoparticles in exhaled air after a single-breath inhalation followed by breath-hold. Recovery refers to the non-deposited particle fraction. The aim
It is common practice in India to consume the dairy drink buttermilk as a way of mitigating occupational heat strain. This paper explores the thermoregulatory and hydration benefits of drinking buttermilk but also the impacts of work in a hot environment on the gut microbiota, renal and cognitive function. Twelve healthy participants were subjected to a 3-h period of medium load physical intermitt
The perception of danger represents an essential ability of prey for gaining an informational advantage over their natural enemies. Especially in complex environments or at night, animals strongly rely on chemoreception to avoid predators. The ability to recognize danger by chemical cues and subsequent adaptive responses to predation threats should generally increase prey survival. Recent findings
Elementary Motion Detectors (EMD) are well-established models of visual motion estimation in insects. The response of EMDs are tuned to specific temporal and spatial frequencies of the input stimuli, which matches the behavioural response of insects to wide-field image rotation, called the optomotor response. However, other behaviours, such as speed and position control, cannot be fully accounted
The aim of this study was to investigate calcium chloride-induced gelatinization of oat starch, and its effects on the properties of oat starch-based Pickering emulsions. The starch granules were gelatinized in CaCl2 for up to 24 h and the results indicate that the salt-induced gelatinization of oat granules is not a surface phenomenon, as gelatinization and dissolution of the whole starch granule
Experimentally and theoretically determined shielding factors for a common light construction dwelling type were obtained and compared. Sources of the gamma-emitting radionuclides 60Co and 137Cs were positioned around and on top of a modular building to represent homogeneous fallout. The modular building used was a standard prefabricated structure obtained from a commercial manufacturer. Four refe
Improving our understanding of the relationships between biodiversity and the delivery of ecosystem services is crucial for the development of sustainable agriculture. We introduce a novel framework that is based on the identification of indicator species for single or multiple ecosystem services across taxonomic groups based on indicator species analyses. We utilize multi-species community data (
Engineers and scientist have a long tradition in trying to improve the thermophysical properties of convective heat carriers such as water and transformer oil. Technological developments of the last decades allow the dispersion of particle of sizes ranging between 10 and 100 nm in these liquids. In a large number of recent studies the resulting nanofluids have been reported to display anomalously
The principal aim of my PhD research is to think through practices involved in the making of In the Desert of Modernity. Colonial Planning and After (Berlin 2008, Casablanca 2009), that constituted as well as traversed the exhibitions and went beyond. The project developed through a transnational constellation of culture producers, scholars, and activists from Berlin, Zurich, Paris, Delft and Casa
The incidence of type 1 diabetes (T1D) in Sweden is one of the highest in the world. However, the possibility of other types of diabetes must also be considered. In addition, individuals with T1D constitute a heterogeneous group. A precise classification of diabetes is a prerequisite for optimal outcome. For precise classification, knowledge on the distribution of genetic factors, biochemical mark
