Double quantum dots (DQDs) hold great promise as building blocks for quantum technology as they allow for two electronic states to coherently couple. Defining QDs with materials rather than using electrostatic gating allows for QDs with a hard-wall confinement potential and more robust charge and spin states. An unresolved problem is how to individually address these QDs, which is necessary for co
Tissue arachidonic acid (AA) pools originate from the diet, and from hepatic and extrahepatic desaturation-elongation of dietary linoleic acid (LA). This review summarizes the roles of absorption, transport, and formation of AA in the buildup of tissue AA pools. In humans who ingest 0.2-0.3 g of AA and 10-20 g of LA per day on a Western diet, the formation of AA from LA exceeds the dietary supply
In an era increasingly defined by insecurity and populist politics, India has emerged as a forceful ontological security provider under the leadership of Marendra Modi. If ontological security is about finding a safe (imagined) haven, then ontological insecurity is about the lack of such a space in narrative terms. Drawing on Lacanian understandings of ‘the imaginary’ as something that can fill an
The proportion of smokers in this study was significantly lower among patients with ulcerative colitis (13%) than among patients with Crohn's disease (47%), the difference being significant for both sexes and for the age groups both below and above 40 years. The proportion of male ex-smokers among patients with ulcerative colitis (28%) was higher than among patients with Crohn's disease (8%), wher
X-linked agammaglobulinemia (XLA) is an immunodeficiency caused by mutations in the gene coding for Bruton's agammaglobulinemia tyrosine kinase (BTK). A database (BTKbase) of BTK mutations has been compiled and the recent update lists 368 entries from 318 unrelated families showing 228 unique molecular events. In addition to mutations the database lists also some polymorphisms and site-directed mu
The glial cell line-derived neurotrophic factor (GDNF)-family of neurotrophic factors consisted until recently of three members, GDNF, neurturin, and persephin. We describe here the cloning of a new GDNF-family member, neublastin (NBN), identical to artemin (ART), recently published (Baloh et al., 1998). Addition of NBN/ART to cultures of fetal mesencephalic dopamine (DA) neurons increased the num
Little is know about whether the conditions experienced during ontogeny affect resistance to parasites later in life in wild animals. Here, we used a population of blue tits (Cyanistes caeruleus (L., 1758)) to investigate to what extent conditions experienced during the nestling stage could explain the ability to control blood parasite (Haemoproteus majoris (Laveran, 1902)) infections 1 year later
Background: As a part of a set of reforms launched in 1995, 10 pilot case management services were established in Sweden, which have been subject to an evaluation with regard to outcome and changes in use of services. The present study was designed to provide information about client outcomes over a 6-year follow-up period. Aims: The aim of the study was to investigate changes during the follow-up
This study investigated to what extent, and under what circumstances, pair collaboration influences the realism in eyewitness confidence in event memory. The participants first saw a short film clip and then confidence rated their answers to questions on its content. A condition (the Individual-Pair condition) where individual effort preceded pair collaboration showed better calibration compared w
Athernsclerotic renal artery stenosis (ARAS) may cause hypertension, progressive renal failure, and recurrent pulmonary edema. It typically occurs in high risk patients with coexistent vascular disease elsewhere. Most patients with ARAS are likely to die from coronary heart disease or stroke before end-stage renal failure occurs. Recent controlled trials have shown that most patients undergoing an
More aggressive therapy including cytotoxic drugs is increasingly used in the treatment of rheumatoid arthritis (RA), and may confer increased susceptibility to infections. Septic arthritis is one infectious complication known to be overrepresented in RA. We studied the impact of disease severity and medication in a group of nine RA patients with proven septic arthritis, excluding those occurring
This study evaluates a novel method for extracting roots from soil samples and applies it to estimate standing crop root mass (+/- confidence intervals) in an eastern Amazon rainforest. Roots were manually extracted from soil cores over a period of 40 min, which was split into 10 min time intervals. The pattern of cumulative extraction over time was used to predict root extraction beyond 40 min. A
Causality tests in the Granger's sense are increasingly applied in empirical research. Since the unit root revolution in time-series analysis, several modifications of tests for causality have been introduced in the literature. One of the recent developments is the Toda-Yamamoto modified Wald (MWALD) test, which is attractive due to its simple application, its absence of pre-testing distortions, a
An assay has been established for quantitative evaluation of lentivirus coreceptor use with the help of GHOST(3) cells. GHOST(3) cells were derived from the human osteosarcoma cell line, HOS, and have been engineered to stably express CD4 and one or another of the chemokine receptors CCR3, CCR5, CXCR4, CXCR6/STRL33/Bonzo, or the orphan receptor GPR15/BOB. The indicator cell line carries the HIV-2
Osteonecrosis of the femoral head following femoral neck fractures is a common condition. Spontaneous osteonecrosis, is, however, a rare disorder, which is observed with increased frequency in alcohol abusers. In this retrospective study, we followed 512 consecutive male patients who had sustained femoral neck fractures between 1984 and 1992; 82 of these 512 patients (16%) had earlier been registe
