A Random Coefficient Approach to the Predictability of Stock Returns in Panels
Most studies of the predictability of returns are based on time series data, and whenever panel data are used, the testing is almost always conducted in an unrestricted unitby- unit fashion, which makes for a very heavy parametrization of the model. On the other hand, the few panel tests that exist are too restrictive in the sense that they are based on homogeneity assumptions that might not be tr
Search for Pair Production of a Heavy Up-Type Quark Decaying to a W Boson and a b Quark in the lepton plus jets Channel with the ATLAS Detector
A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming subsequent decay to a W boson and a b quark, t'(t) over bar' -> W(+)bW(-)(b) over bar. The search is based on 1.04 fb(-1) of proton-proton collisions at root s = 7 TeV collected by the ATLAS detector at the CERN Large Hadron Collider. Data are analyzed in the lepton + jets final state, chara
Nuclear Modification of psi ', chi(c), and J/psi Production in d plus Au Collisions at root s(NN)=200 GeV
We present results for three charmonia states (psi' chi(c), and J/ psi) in d + Au collisions at vertical bar y vertical bar < 0.35 and root s(NN) = 200 GeV. We find that the modification of the psi' yield relative to that of the J/ psi scales approximately with charged particle multiplicity at midrapidity across p + A, d + Au, and A + A results from the Super Proton Synchrotron and the Relativisti
The tyrosine kinase CSK associates with FLT3 and c-Kit receptors and regulates downstream signaling.
Type III receptor tyrosine kinases (RTKs), FLT3 and c-Kit play important roles in a variety of cellular processes. A number of SH2-domain containing proteins interact with FLT3 and c-Kit and regulate downstream signaling. The SH2-domain containing non-receptor protein tyrosine kinase CSK is mainly studied in context of regulating Src family kinases. Here we present an addition role of this kinase
Transcription factor Nurr1 maintains fiber integrity and nuclear-encoded mitochondrial gene expression in dopamine neurons
Developmental transcription factors important in early neuron specification and differentiation often remain expressed in the adult brain. However, how these transcription factors function to mantain appropriate neuronal identities in adult neurons and how transcription factor dysregulation may contribute to disease remain largely unknown. The transcription factor Nurr1 has been associated with Pa
Familial risk of early and late onset cancer : nationwide prospective cohort study.
To determine whether familial risk of cancer is limited to early onset cases. Nationwide prospective cohort study. SETTING : Nationwide Swedish Family-Cancer Database. All Swedes born after 1931 and their biological parents, totalling >12.2 million individuals, including >1.1 million cases of first primary cancer. Familial risks of the concordant cancers by age at diagnosis. The highest familial r
Wound edge microvascular blood flow during negative-pressure wound therapy: examining the effects of pressures from -10 to -175 mmHg.
BACKGROUND: Negative-pressure wound therapy is believed to accelerate wound healing by altered wound edge microvascular blood flow. The current standard negative pressure is -125 mmHg. However, this pressure may cause pain and ischemia and often has to be reduced. The aim of the present study was to examine the blood flow effects of different levels of negative pressures (-10 to -175 mmHg). METHOD
Signatures of selection acting on the innate immunity gene Toll-like receptor 2 (TLR2) during the evolutionary history of rodents.
Patterns of selection acting on immune defence genes have recently been the focus of considerable interest. Yet, when it comes to vertebrates, studies have mainly focused on the acquired branch of the immune system. Consequently, the direction and strength of selection acting on genes of the vertebrate innate immune defence remain poorly understood. Here, we present a molecular analysis of selecti

Clonal variegation and dynamic competition of leukemia-initiating cells in infant acute lymphoblastic leukemia with MLL rearrangement.
Distinct from most other acute lymphoblastic leukemia (ALL), infant ALL with mixed lineage leukemia (MLL) gene rearrangement, the most common leukemia occurring within the first year of life, might arise without the need for cooperating genetic lesions. Through Ig/TCR rearrangement analysis of MLL-AF4+ infant ALL at diagnosis and xenograft leukemias from mice transplanted with the same diagnostic
Long-term hygrothermal performance of nuclear reactor concrete containments - Laboratory evaluations of measurement setup, in situ sampling, and moisture flux calculations
A measurement setup for in situ sampling of internal relative humidity and temperature in concrete structures was developed. The setup was used to evaluate the moisture conditions and to determine whether drying of the concrete components within a nuclear reactor containment contributes to the moisture conditions. The measurement setup was tested for accuracy and thereafter installed in Swedish nu
Combined (18) F-fluorocholine and (18) F-fluoride positron emission tomography/computed tomography imaging for staging of high-risk prostate cancer.
Study Type - Diagnosis (cohort) Level of Evidence 2a What's known on the subject? and What does the study add? Positron emission tomography/computed tomography (PET/CT) with choline and fluoride for the detection of metastases in patients with prostate cancer have each been evaluated, with mixed results. Choline PET/CT has been evaluated against pelvic lymphadenectomy, generally with a low sensiti
Fate of citalopram during water treatment with O(3), ClO(2), UV and fenton oxidation
In the present study we investigate the fate of citalopram (CIT) at neutral pH using advanced water treatment technologies that include O(3), ClO(2) oxidation, UV irradiation and Fenton oxidation. The ozonation resulted in 80% reduction after 30min treatment. Oxidation with ClO(2) removed>90% CIT at a dosage of 0.1mgL(-1). During UV irradiation 85% reduction was achieved after 5min, while Fenton w
End-stage renal disease associated with prophylactic lithium treatment.
The primary aim of this study was to estimate the prevalence of lithium associated end-stage renal disease (ESRD) and to compare the relative risk of ESRD in lithium users versus non-lithium users. Second, the role of lithium in the pathogenesis of ESRD was evaluated. We used the Swedish Renal Registry to search for lithium-treated patients with ESRD among 2644 patients with chronic renal replacem
Comprehensive ecosystem model-data synthesis using multiple data sets at two temperate forest free-air CO2 enrichment experiments: Model performance at ambient CO2 concentration
Free-air CO2 enrichment (FACE) experiments provide a remarkable wealth of data which can be used to evaluate and improve terrestrial ecosystem models (TEMs). In the FACE model-data synthesis project, 11 TEMs were applied to two decadelong FACE experiments in temperate forests of the southeastern U.S.the evergreen Duke Forest and the deciduous Oak Ridge Forest. In this baseline paper, we demonstrat
A Benign Vascular Tumor With a New Fusion Gene: EWSR1-NFATC1 in Hemangioma of the Bone.
The EWSR1 gene in chromosome band 22q12 is a promiscuous fusion partner involved in a vast array of tumors characterized by gene fusions. In this study, we report the finding of a new fusion gene, EWSR1-NFATC1, in a hemangioma of the bone; genetic rearrangements have not previously been described in this tumor type. Chromosome banding analysis showed a t(18;22)(q23;q12) translocation as the sole c
Humic substances cause fluorescence inhibition in real-time PCR.
Real-time PCR (qPCR) is the cornerstone of DNA analysis, enabling detection and quantification of minute nucleic acid amounts. However, PCR-based analysis is limited, in part, by the presence of inhibitors in the samples. PCR inhibition has been viewed solely as failure to efficiently generate amplicons, i.e. amplification inhibition. Humic substances (HS) are well known inhibitors of PCR amplific
Novel High-Performing Single-Pressure Combined Cycle With CO2 Capture
The European electric power industry has undergone considerable changes over the past two decades as a result of more stringent laws concerning environmental protection along with the deregulation and liberalization of the electric power market. However, the pressure to deliver solutions in regard to the issue of climate change has increased dramatically in the last few years and has given rise to
