Experimental and modeling study of liquid fuel injection and combustion in diesel engines with a common rail injection system
Fuel injection is one of the most important processes in compression-ignition internal combustion engines owing to its significant impact on the exhaust emissions and thermal efficiency. In this study, experiments were carried out to investigate the influence of injection pressure and injection timing on the temporal evolution of the injection rate and injection duration in a specially designed ex
Search for R-parity-violating supersymmetric particles in multi-jet final states produced in p–p collisions at s=13 TeV using the ATLAS detector at the LHC
Results of a search for gluino pair production with subsequent R-parity-violating decays to quarks are presented. This search uses 36.1 fb−1 of data collected by the ATLAS detector in proton–proton collisions with a centre-of-mass energy of s=13 TeV at the LHC. The analysis is performed using requirements on the number of jets and the number of jets tagged as containing a b-hadron as well as a top
Better for Everyone : An Approach to Multimodal Network Design Considering Equity
We propose a formulation of the Network Design Problem (NDP) to support transport planners in dealing with multimodal networks in contexts characterised by different (and sometimes conflicting) interests and limited resources in a transparent way. We expect that the implementation of the method can increase the acceptability of transport schemes. The proposed formulation expands the scope of tradi
Human thymopoiesis is influenced by a common genetic variant within the TCRA-TCRD locus
The thymus is the primary lymphoid organ where naïve T cells are generated; however, with the exception of age, the parameters that govern its function in healthy humans remain unknown. We characterized the variability of thymic function among 1000 age- and sex-stratified healthy adults of the Milieu Intérieur cohort, using quantification of T cell receptor excision circles (TRECs) in peripheral b
Rapid and efficient induction of functional astrocytes from human pluripotent stem cells
The derivation of astrocytes from human pluripotent stem cells is currently slow and inefficient. We demonstrate that overexpression of the transcription factors SOX9 and NFIB in human pluripotent stem cells rapidly and efficiently yields homogeneous populations of induced astrocytes. In our study these cells exhibited molecular and functional properties resembling those of adult human astrocytes
High Serum Serotonin Predicts Increased Risk for Hip Fracture and Nonvertebral Osteoporotic Fractures : The MrOS Sweden Study
Because several studies have implicated serotonin as a regulator of bone mass, we here explore its potential association on fracture risk and falls, as on bone mineral density (BMD) and muscle strength, in humans. Serum levels of serotonin were analyzed in 950 men (aged 69 to 81 years), participating in the Gothenburg part of the population-based study MrOS Sweden. Men taking selective serotonin r

Least Squares and Maximum Likelihood Estimation of Mixed Spectra
In this paper, we propose a novel 1-D spectralestimator for signals with mixed spectra. The proposed methodis partly based on the recently introduced smooth spectralestimator LIMES, in which the smoothness is accounted for byassuming linearity within predefined segments of the spectrum.The proposed method utilizes this formulation but also allowssegments to change size to better estimate the spect
Bible Study: Jacob Reconciled with Esau
A Neuron-Based Pulse Servo for Motion Control
Sensory control based on biological computational paradigms can be implemented using low-power analog very large-scale integrated circuitry. We describe a design frame and a set of circuit elements with which generic motor controllers can be implemented. We then embed a simple proportional-derivative motor controller in the design frame, and describe its performance advantages over a more traditio
Biomanipulating streams : a supplementary tool in lake restoration
Removal of cyprinid fish is a widely used biomanipulation tool to transform turbid shallow eutrophic lakes in north temperate regions into a clear water state. We here evaluate the removal of cyprinids from streams as a supplement to lake fishing. Since cyprinids often aggregate in high densities in lake inlet/outlet streams during winter migration, removal of fish in this space-confined habitat m

Study of Deiodinase Type 2 Polymorphisms in Graves' Disease and Ophthalmopathy in a Swedish Population
Background: Deiodinase type 2 (DIO2) is an enzyme that catalyzes the production of the active form of thyroid -hormone triiodothyronine (T3) from thyroxine (T4) and is important for maintaining intracellular T3 levels. Single nucleotide polymorphisms (SNPs) in DIO2 were associated with several diseases. The association of SNPs in DIO2 with Graves' disease (GD) was suggested in 2 Russian studies. O
Aplasia of the right aortic cusp in a neonate : a life-threatening but curable anomaly
A case of absent right aortic cusp causing serious aortic incompetence in a neonate is reported. A "bicuspidalization" repair broke down within 24 hours, but reoperation with annular enlargement and insertion of a 19-mm prosthetic valve resulted in complete recovery. This rare but life-threatening anomaly of the aortic valve can be recognized with Doppler echocardiography. Valve replacement in con
Review: Web-based brief interventions for young adolescent alcohol and drug abusers - a systematic review
BackgroundAdolescents’ use of alcohol, cannabis and other psychoactive substances has significantly increased in European countries. Parallel to this web-based screening and brief intervention have been disseminated. An important question is if it is based on evidence for effect? Therefore, the aim of this review is to evaluate the evidence for effect. MethodA systematic literature search was perf
Smoking cessation intervention in emergency neurology - introduction of a new practice
Introduction Emergency neurological patients are rarely given opportunities for smoking and alcohol intervention. How-ever, both are relevant in the acute phase as well as in future rehabilitation.Objectives The aim of this study was primarily to illustrate the implementation of motivational counselling in an acute neurological department and also to predict factors influencing this motivation.Met
Smoking cessation intervention activities and outcomes before, during and after the national Healthcare Reform in Denmark
BackgroundMany countries and regions undergo structural changes that intent to improve the effectiveness and quality of care. Until 2007, the municipalities, counties, hospitals and pharmacies shared the smoking cessation activities almost equally in Denmark. Among others, the Danish Healthcare Reform 2007 intended to add responsibility for smoking cessation intervention at county level to the mun
Some New Analytic and Computational Results for Operator Riccati Equations
The operator Riccati equation associated with a distributed parameter quadratic cost-linear dynamics control process is considered.Making use of ideas from transport theory, a derivation of a generalized version of the X-Y functions of radiative transfer is given, and it is seen that, under commonly occurring conditions, the new equations may be easier to numerically resolve than the original Ricc
