Acquiring once, acquiring twice - Lessons learned from repeated acquisitions of innovative firms

This paper describes and discusses learning in repeated acquisitions of innovative firms. Researchers have pointed to how companies may improve performance through conducting repeated acquisitions, while they have not previously focused on repeated acquisitions of innovative firms. Findings of this present study are summarised in five learnings: forming a professional organisation that deals with

A toxicological and dermatological assessment of alkyl cyclic ketones when used as fragrance ingredients The RIFM Expert Panel

The alkyl cyclic ketone (ACK) fragrance ingredients are a diverse group of structures with Similar metabolic and toxicity profiles. ACK fragrance materials demonstrate low acute toxicity. Upon repeat dose testing, some adverse effects in biochemical and hematological parameters, and slightly increased liver and kidney weights were reported, primarily at high doses, resulting from adaptive effects.

A neural network clustering algorithm for the ATLAS silicon pixel detector

A novel technique to identify and split clusters created by multiple charged particles in the ATLAS pixel detector using a set of artificial neural networks is presented. Such merged clusters are a common feature of tracks originating from highly energetic objects, such as jets. Neural networks are trained using Monte Carlo samples produced with a detailed detector simulation. This technique repla

Microstructural and Residual Stress Development due to Inertia Friction Welding in Ti-6246

A thorough investigation has been performed to assess the microstructural properties, mechanical properties (hardness and elastic modulus), and residual stress development in Ti-6Al-2Sn-4Zr-6Mo (Ti-6246) inertia friction welds in the as-welded and postweld heat-treated conditions. It was evident that the thermomechanical deformation in the weld region occurred above the beta transus, forming dynam

The Electron-ion Scattering Experiment ELISe at the International Facility for Antiproton and Ion Research (FAIR) - A Conceptual Design Study

The electron-ion scattering experiment ELISe is part of the installations envisaged at the new experimental storage ring at the International Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. It offers an unique opportunity to use electrons as probe in investigations of the structure of exotic nuclei. The conceptual design and the scientific challenges of ELISe are presented.

Artikeln undersöker hur berättelser om människor och apor, från scala natuae, via evolutionsberättelsen till moderna romaner förhållit sig till konstruktionen av tid och temporalitet - hur exempelvis bilden av tävling mellan människa och apa - där människan tar sig upp och fram, medan apan hamnar på efterkälken, bidragit till idén om progressiv, kronologisk tid, medan andra mer hybridiska berättel

Valence bond liquid phase in the honeycomb lattice material Li2RuO3

The honeycomb lattice material Li2RuO3 undergoes a dimerization of Ru4+ cations on cooling below 270 degrees C, where the magnetic susceptibility vanishes. We use density functional theory calculations to show that this reflects the formation of a valence bond crystal, with a strong structural bond disproportionation. On warming, x-ray diffraction shows that discrete threefold symmetry is regained

Search for Higgs boson pair production in the [Formula: see text] final state from pp collisions at [Formula: see text] TeVwith the ATLAS detector.

A search for Higgs boson pair production [Formula: see text] is performed with 19.5 fb[Formula: see text] of proton-proton collision data at [Formula: see text] TeV, which were recorded by the ATLAS detector at the Large Hadron Collider in 2012. The decay products of each Higgs boson are reconstructed as a high-momentum [Formula: see text] system with either a pair of small-radius jets or a single

DNA methylation protects hematopoietic stem cell multipotency from myeloerythroid restriction

DNA methylation is a dynamic epigenetic mark that undergoes extensive changes during differentiation of self-renewing stem cells. However, whether these changes are the cause or consequence of stem cell fate remains unknown. Here, we show that alternative functional programs of hematopoietic stem cells (HSCs) are governed by gradual differences in methylation levels. Constitutive methylation is es

The use of ultrasound in the prediction of endometrial cancer in women with postmenopausal bleeding

The aim of the work presented in this thesis was to identify the ultrasound methods and ultrasound features that are most useful for the prediction of endometrial cancer in patients with postmenopausal bleeding and sonographic endometrial thickness 4.5 mm or more. The grey-scale ultrasound variable that best predicted malignancy was heterogeneous endometrial echogenicity (area under the receiver o

Vem är gäst och främling — och vad betyder det?

Starting in the story about Lot and the visiting angels in Genesis 19, I reflect in this article on the relation between guest and host. What are the demands and requirements from both sides? Perhaps one is more restricted than is often thought, restricted by expectations from the other and by expectations from people around. Also, perhaps the roles may change, the host being treated as guest for

Partial Enumeration and Curvature Regularization

Energies with high-order non-submodular interactions have been shown to be very useful in vision due to their high modeling power. Optimization of such energies, however, is generally NP-hard. A naive approach that works for small problem instances is exhaustive search, that is, enumera- tion of all possible labelings of the underlying graph. We propose a general minimization approach for large gr

Systemic Lupus Erythematosus, with focus on vascular wall changes, cardiac risk-factor awareness and cardiovascular events

Popular Abstract in Swedish SAMMANFATTNING PÅ SVENSKA Systemisk Lupus Erytematosus (SLE) är en kronisk inflammatorisk system sjukdom. Sjukdomen yttrar sig med stor variation, både avseende vilka organ områden och med vilken intensitet olika organ kan bli engagerade. Genom åren har prognosen för sjukdomen i sig dramatiskt förbättrats, genom att alla typer av organ manifestationer kan behandlas. SeSystemic Lupus Erythematosus is an autoimmune disease with a wide range of disease manifestations with respect to severity and magnitude of organ involvement. An increased risk of cardiovascular disease (CVD) compared with the general population causes both morbidity and mortality in SLE patients. Consequently prevention, early detection and treatment of arteriosclerotic manifestations are of high

Production of polyhydroxyalkanoates by activated sludge treating a paper mill wastewater

Production of polyhydroxyalkanoates (PHAs) in activated sludge treating wastewater represents an economical and environmental promising alternative to pure culture fermentations. A process for production of PHA from a paper mill wastewater was examined at laboratory scale. The three stage process examined consisted of acidogenic fermentation to convert wastewater organic matter to volatile fatty a

Real-time ultrasound vs. evaluation of static images in the preoperative assessment of adnexal masses

Objective To determine if the prediction of the Malignancy of all adnexal mass using pattern recognition, i.e. subjective evaluation of gray-scale and Doppler ultrasound findings, is as accurate when based on static images as it is when based on a real-time ultrasound examination. Methods The static images of 166 non-consecutive patients with 'difficult' adnexal masses, who all underwent surgery a

Network Analysis of a Large Scale Open Source Project

Industry involvement in open source software development has become a popular practice among companies which, e.g., share software development costs with other community participants or implement an open source based business model. An increased understanding of the underlying development structure, especially in a case where the community participants are composed of competing industry members, c

Constraining the process of Eoarchean TTG formation in the Itsaq Gneiss Complex, southern West Greenland

We present new major and trace element, high-precision high-field-strength-element, hafnium and neodymium isotope data for well preserved Eoarchean TTGs within the Itsaq Gneiss Complex (IGC) of southern West Greenland. These data are combined with thermodynamic model predictions of partial melting and fractional crystallization to gain new insights into continental crust formation in the Archean.

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals

Azimuthal correlations of electrons from heavy-flavor decay with hadrons in p plus p and Au plus Au collisions at root s(NN)=200 GeV

Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled p+p collisions. These measurements indicate that charm and bottom quarks interact with the hot dense matter produced in heavy-ion collisions much more than expected. Here we extend these studies to two-particle correlations w
