The design of the InP drain layer in asymmetric InGaAs/InP MOSFETs has been studied experimentally. The influence of doping and thickness of the InP drain has been carefully measured and compared with the performance with an InGaAs drain, regarding the output conductance, the voltage gain, and the leakage current. It is shown that the introduction of an undoped InP spacer has a profound effect on
Context.Innovation is promoted in companies to help them stay competitive. Four types of innovation are defined: product, process, business, and organizational. Objective. We want to understand the perception of the innovation concept in industry, and particularly how the innovation types relate to each other. Method. We launched a survey at a branch of a multi-national corporation. Results. From
Background: The chemical senses of insects mediate behaviors that are closely linked to survival and reproduction. The order Diptera contains two model organisms, the vinegar fly Drosophila melanogaster and the mosquito Anopheles gambiae, whose chemosensory genes have been extensively studied. Representing a third dipteran lineage with an interesting phylogenetic position, and being ecologically d
Background: Osteoarthritis (OA) is a degenerative disease, considered to be one of the major public health problems. Research suggests that patient education is feasible and valuable for achieving improvements in quality of life, in function, well-being and improved coping. Since 1994, Primary Health Care in Malmo has used a patient education programme directed towards OA. The aim of this study wa
Wolmer-Solberg et al., reported that six human neuroblastoma cell lines and the vast majority of clinical neuroblastoma samples contained HCMV DNA and expressed HCMV proteins. We could not replicate the data and therefore remain skeptical towards the prevalence of HCMV DNA in neuroblastomas.
Large cell carcinoma with or without neuroendocrine features (LCNEC and LC, respectively) constitutes 3-9% of non-small cell lung cancer but is poorly characterized at the molecular level. Herein we analyzed 41 LC and 32 LCNEC (including 15 previously reported cases) tumors using massive parallel sequencing for mutations in 26 cancer-related genes and gene fusions in ALK, RET, and ROS1. LC patient
Verkstadsmaterial från vendeltid från östra Skåne. En ansamling näbbfibulor, uppenbarligen inte färdiga. Materialet är att uppfattas om ett verkstadslager. Ger inblickar i tillverkningsprocess och regionala hantverkstraditioner.
Background: The incidence of non-Hodgkin lymphoma (NHL) in early life has increased in recent decades, but the relevant risk factors remain largely unknown. We examined perinatal and family risk factors for NHL in childhood through young adulthood. Methods: We conducted a national cohort study of 3 571 574 individuals born in Sweden in 1973-2008 who were followed for incidence of NHL through 2009
Kan barndomens häpnad över ”märkvärdiga ting” påverka våra vuxna värderingar? För inte så länge sedan – ännu i mannaminne – visades exotiska folkslag på cirkus. Färgar detta första möte med det annorlunda vår människosyn?
Shredder residues of end-of-life vehicles and white goods are a complex waste stream, which nowadays most often is disposed of at industrial landfills. This paper describes the most important findings concerning the complex composition of the landfill leachate and its on-site, year-round treatment under cold-climate conditions. A 3-year investigation has confirmed that concentrations of different
In this study, a new supercritical fluid chromatography-mass spectrometry (SFC-MS) method has been developed for the separation of nine vitamin D metabolites within less than eight minutes. This is the first study of analysis of vitamin D and its metabolites carried out by SFC-MS. Six columns of orthogonal selectivity were examined, and the best separation was obtained by using a 1-aminoanthracene
Since 2009, Japanese civil society groups have arranged exhibitions in China dealing with the so-called comfort women issue in cooperation with local Chinese organizers, including state-run war museums that function as patriotic education bases. Organizing these exhibitions has required much time and energy. A fundamental aim of these groups is to make the Japanese government compensate the victim
In order to reduce its environmental impact, the chemical industry no longer produces base chemicals such as ethylene, solely from fossil, but also from biomass-based feedstocks. However, a biomass option suitable for one region might not be as suitable for another region due to, e.g., long transport and the related environmental. Therefore, local biomass alternatives and the environmental impact
This paper concerns the use of the expectation-maximisation (EM) algorithm for inference in partially observed diffusion processes. In this context, a well known problem is that all except a few diffusion processes lack closed-form expressions of the transition densities. Thus, in order to estimate efficiently the EM intermediate quantity we construct, using novel techniques for unbiased estimatio
The article considers the importance of frontier studies in historical archaeology and discusses applicability of some of the concepts deriving from postcolonial theories for a better understanding of human relationships in the frontier zones. The conditions of frontiers and borderlands are compared with the characteristics of the “Third Space” described by Homi Bhabha as a realm of negotiation, t
