We investigate in detail the optical anisotropy of absorption of linearly polarized light in InAs/GaSb quantum wells grown on GaSb along the [001] direction, which can be used as an active region of different laser structures. The energy level positions, the wave functions, the optical matrix elements, and the absorption coefficients are calculated using the eight-band k center dot p model and the
Using a direct imaging method, we experimentally investigate the reversal of magnetic islands in a bit-patterned media sample based on a pre-patterned substrate. Due to systematic variation of the island distances in the media, we are able to study the influence of the dipolar interaction on the switching-field distribution of the island ensemble. The experimental findings are explained by an anal
This comment on Larner's (2011) article deals with the political power of certain conceptualisations of neoliberalism and questions the Anglo-American ways of reading the history of neoliberalism. The inclusion of key moments of neoliberalisation and crisis outside the Anglo-American world would provide different readings of the processes of neoliberalisation. The ‘choice’ of crises matters for ou
Crayfish spermatophores are deposited on the body surface of the female during mating and remain there for a period of time before fertilization ensues. Post-mating changes in protein expression level in the noble crayfish Astacus astacus spermatophore were quantified. In-gel digestion and high resolution mass spectrometry were used for label-free protein quantification. One hundred twelve protein
Transition to adulthood for adolescents in general is a multifaceted process, and for adolescents with cerebral palsy (CP) it also involves transition from child- to adult-oriented support. CP entails a variety and combination of disabilities, which in association with external factors may make the transition to adult health services difficult. The aim of this study was to gain a deeper understand
Aphids are among the most severe invertebrate pests of crops and cause high economic losses. The control of aphids by natural enemies is an essential ecosystem service with high relevance to management strategies applied in agricultural plant production and horticulture. However, the current knowledge on the effectiveness of specialist and generalist predators in aphid control with respect to host
AIMS: Children with type 1 diabetes (T1D) risk and islet autoantibodies are recruited to a secondary prevention study. The aims were to determine metabolic control in relation to human leukocyte antigen (HLA) genetic risk and islet autoantibodies in prepubertal children. METHODS: In 47 healthy children with GADA and at least one additional islet autoantibody, intravenous glucose tolerance test (Iv
We have examined the geometric and electronic structures of iron phthalocyanine assemblies on a Cu(111) surface at different sub- to mono-layer coverages and the changes induced by thermal annealing at temperatures between 250 and 320 °C by scanning tunneling microscopy, x-ray photoelectron spectroscopy, and x-ray absorption spectroscopy. The symmetry breaking observed in scanning tunneling micros
It remains unknown whether human papillomaviruses (HPVs) or human herpesviruses (HHVs) in semen affect sperm DNA integrity. We investigated whether the presence of these viruses in semen was associated with an elevated sperm DNA fragmentation index. Semen from 76 sperm donors was examined by a PCR-based hybridization array that identifies all HHVs and 35 of the most common HPVs. Sperm DNA integrit
Due to variation in pH, ionizable pharmaceuticals entering aquatic environments experience different degrees of ionization, which may affect toxicity. Using data from toxicity testing at only neutral pH may potentially under- or overestimate actual toxicity at pH ranges found in natural aquatic environments. Here we show relative pH-dependent acute toxicity to Daphnia magna for the pharmaceutical
This paper presents an analysis of energy dissipation of a decimation filter chain of four half band digital (HBD) filters operated in the sub-threshold (sub-VT) region with throughput constraints. To combat speed degradation due to scaling of supply voltage, various HBD filters are implemented as unfolded structures. The designs are synthesized in 65 nm CMOS technology with low-power and three th
This paper discusses how physical planning works with place-making through urban design to support image creation in a municipality that aims to create a new image for its city. Two large-scale urban development projects in Sweden are analysed. The analysis focuses on official plans and documentation, and expert interviews. It distinguishes how place-making by physical planning happens through aes
The role of oxidants in viral diseases is fairly complex because it includes metabolic regulation both of host metabolism and viral replication. However, a role for reactive oxygen species (ROS) and reactive nitrogen species (RNS) as mediators of virus-induced lung damage is supported by studies and antioxidants can thus be expected to act at many different levels. The aim of the present pilot stu
Objective: To evaluate if the measurement of survivin in the blood of patients with rheumatoid arthritis (RA) undergoing infliximab treatment has predictive value for treatment response. Methods: The study included 87 consecutive RA patients (age 24-89 years, disease duration 18-526 months) treated with regular infusions of influximab. Survivin levels were measured by enzyme-linked immunosorbent a
Cycling as a transport mode has gradually become more attractive in cities during the last 10 years. However, not all cities give due consideration to cycling issues in the planning process. In many transport systems, cycling and issues of vélomobility are still neglected. Recent research considers several aspects of cycling, however, few studies have shown why differences in for example modal spl
Through the concept of friction, this article critically examines how the liberal peace travels across differences, accommodates, as well as is accommodated by the spaces it engages, and how it transforms, enables or constrains local as well as international agency. As the liberal peace interplays with the post-conflict realities three sites of friction are identified and examined in the divided c
Secondary hyperparathyroidism persists after renal transplantation in a substantial number of patients. Primary hyperparathyroidism and secondary hyperparathyroidism are both associated with abnormalities in glucose metabolism, such as insufficient insulin release and glucose intolerance. The association of hyperparathyroidism and diabetes after renal transplantation has, as far as we know, not be
OBJECTIVE: To investigate the role of the Fc(α)RI 844 A>G functional polymorphism in the genetic predisposition to rheumatoid arthritis (RA) and systemic sclerosis (SSc) susceptibility. METHODS: The study population was composed of 1401 patients with SSc, 642 patients with RA, and 1317 healthy controls. The Fc(α)RI (CD89) single-nucleotide polymorphism rs16986050 was genotyped by pyrosequencing. R
