We have fabricated single balanced down-conversion mixer circuits using InAs nanowire MOSFETs as both active and passive devices. This is achieved by a combination of electron beam lithography and UV-lithography with a line width of 12 mu m. The circuits exhibit a low frequency voltage conversion gain of 6 dB, a -3 dB cutoff frequency of 2 GHz and a power consumption of 3.8 mW, while operating at
In object-oriented programs, the relationship of an object to many objects is usually implemented using indirection through a collection. This is in contrast to a relationship to one object, which is usually implemented directly. However, using collections for relationships to many objects does not only mean that accessing the related objects always requires accessing the collection first, it also
The boreal forest carbon balance is predicted to be particularly sensitive to climate change. Carbon balance estimates of these biomes stem mainly from eddy-covariance measurements of net ecosystem exchange (NEE). However, a full net ecosystem carbon balance (NECB) must include the lateral carbon export (LCE) through discharge. We show that annual LCE at a boreal forest site ranged from 4 to 28%,
The varieties of capitalism literature has drawn little attention to industrial renewal and diversification, while the related diversification literature has neglected the institutional dimension of industrial change. Bringing together both literatures, the paper proposes that institutions have an impact on the direction of the diversification process, in particular on whether countries gain a com
Background: Pain is a common condition among prehospital patients. The present study is designed to determine whether adding low-dose ketamine as additional analgesia improves the pain/nausea scores and hemodynamic parameters compared to morphine sulphate alone among patients with bone fractures. Methods: Prospective, prehospital clinical cohort study. Twenty-seven patients were included with acut
This paper estimates the health returns to schooling, using a twin design. For this purpose, I use data on monozygotic twins from the Midlife in the United States survey. The results suggest that completing high school improves health, as measured through self-reported health, chronic conditions, and exercise behavior, but that additional schooling does not lead to additional health gains. Control
Objective: To analyse the outcome of cerebral venous thrombosis (CVT) patients presenting with isolated headache, specifically to compare isolated headache patients with early vs. late CVT diagnosis. Method: In the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT) database we compared the outcome of patients with isolated headache and a CVT diagnosed early (<= 7 days from ons
The overall aim of this thesis was to explore loneliness by identifying associated factors and predictors for loneliness among older people. This research was also undertaken to examine the association between loneliness and healthcare consumption. In addition, the reserach explored the experience of loneliness and evaluated the effects on loneliness, symptoms of depression and life satisfaction o
The nomenclature of Gallowayella, Golubkovaea, Oxneria, and some species of Gyalolechia, Leproplaca, and Rusavskia in the Teloschistaceae is corrected and commented. Rusavskia ectaniza is a new combination. Also the earlier invalidly published combinations Gyalolechia bassiae, Leproplaca chrysodeta, and Rusavskia aspera are validated.
This article examines the explosion of artistic production in the Arab world during the so-called Arab Spring. Focusing on music, poetry, theatre, and graffiti and related visual arts, I explore how these do-it-yourself scenes represent, at least potentially, a return of the aura to the production of culture at the edge of social and political transformation. At the same time, the struggle to reta
Introduction: In contact zones, genetic mixing of two taxa can be restricted by prezygotic (e.g. assortative mating) or postzygotic (lower fitness of hybrid offspring) barriers, or a combination of the two. A hybrid zone between two willow warbler subspecies (Phylloscopus trochilus trochilus, P. t. acredula) with distinctive migratory strategies occurs in central Sweden. These subspecies exhibit d
Background: Testosterone has been attributed importance for various aspects of behaviour. The aim of our study was to investigate the potential influence of 2 functional polymorphisms in the amino terminal of the androgen receptor on personality traits in men. Methods: We assessed and genotyped 141 men born in 1944 recruited from the general population. We used 2 different instruments: the Karolin
In this study, numerical simulations are conducted to investigate the effects of dimple positions on the endwall heat transfer and friction factor in a pin fin wedge duct. The dimple diameter is the same as the pin fin diameter, while the ratio between dimple depth and dimple diameter is 0.2. Three different dimple positions are investigated (i.e., directly upstream of the pin fins, in a staggered
The integration of scheduling and control in the process industry is a topic that has been frequently discussed during the recent years, but many challenges remain in order to achieve integrated solutions that can be implemented for large-scale industrial sites. In this paper we consider production control under disturbances in the supply of utilities at integrated sites together with the integrat
The binding of mucin to water-soluble copolymers of N,N-dimethylacrylamide and N-acryloyl-m-aminophenylboronic acid grafted on the surface of glass is studied. Atomic force microscopy studies show that many graft copolymer islands 20-200 nm in diameter and 50 nm in height occur on the modified surface of flat glass. Owing to the presence of phenyl boronate groups, the copolymer behaves as a weak p
