Sub-Optimization of a claw-pole structure according to material properties of soft magnetic materials
The focus of this paper is on the development of a single phase PM machine with wave-windings where the design variables are the winding layout and design of a soft magnetic powder core for a stator. A number of BH curves are synthesised in order to characterise some of the existing powder cores and to study the influence of magnetic permeability on starting torque and mean driving torque. The goa
Adding attenuation corrected images in myocardial perfusion imaging reduces the need for a rest study.
The American Society of Nuclear Cardiology and the Society of Nuclear Medicine conclude that incorporation of attenuation corrected (AC) images in myocardial perfusion scintigraphy (MPS) will improve diagnostic accuracy. The aim was to investigate the value of adding AC stress-only images for the decision whether a rest study is necessary or not.
When the dust has settled: A final note on replication
Honing and Samuelsson have in a two papers (2014, 2015) criticized the Delmar and Shane (2003) paper on several grounds: The data are difficult to replicate; conflicting results with another paper using the same data and similar independent variable; the inability to fully rule out reversed causality because of tied events; and what is the choice of relevant dependent variable. I also commented on
Medkänslans makt och gränser. Nya linjer i känslornas historia
Den här artikeln belyser hur långa linjer kan bedrivas också kring känslor som omsorg och medkänsla. Därigenom önskar vi nyansera en traditionell berättelse om västerlandets historia, som i hög grad förklarat historien som en förnuftslig och handgriplig triumf över tidigare dominerande känslor som ångest och rädsla. En sådan förklaringsmodell baseras på teorier om känslor som inte längre har stöd
Early adiposity rebound predicts overweight and obesity at 15 years of age
Crosslinked plastic scintillators: A new detection system for radioactivity measurement in organic and aggressive media
The measurement of radioactive solutions containing organic or aggressive media may cause stability problems in liquid and plastic scintillation (PS) techniques. In the case of PS, this can be overcome by adding a crosslinker to the polymer structure. The objectives of this study are to synthesise a suitable crosslinked plastic scintillator (C-PS) for radioactivity determination in organic and agg
Organisational hazards when treating patients with cytotoxic drugs
Graphene coatings for chemotherapy: avoiding silver-mediated degradation
Chemotherapy treatment usually involves the delivery of fluorouracil (5-Fu) together with other drugs through central venous catheters. Catheters and their connectors are increasingly treated with silver or argentic alloys/compounds. Complications arising from broken catheters are common, leading to additional suffering for patients and increased medical costs. Here, we uncover a likely cause of s

TiO2 chemical vapor deposition on Si(111) in ultrahigh vacuum: Transition from interfacial phase to crystalline phase in the reaction limited regime
The interaction between the metal organic precursor molecule titanium(IV) isopropoxide (TTIP) and three different surfaces has been studied: Si(111)-(7 x 7), SiOx/Si(111) and TiO2. These surfaces represent the different surface compositions encountered during TTIP mediated TiO2 chemical vapor deposition on Si(111). The surface chemistry of the titanium(IV) isopropoxide precursor and the film growt

Monotone spectral density estimation
We propose two estimators of a monotone spectral density, that are based on the periodogram. These are the isotonic regression of the periodogram and the isotonic regression of the log-periodogram. We derive pointwise limit distribution results for the proposed estimators for short memory linear processes and long memory Gaussian processes and also that the estimators are rate optimal.
The SKI proto-oncogene enhances the in vivo repopulation of hematopoietic stem cells and causes myeloproliferative disease
The proto-oncogene SKI is highly expressed in human myeloid leukemia and also in murine hematopoietic stem cells. However, its operative relevance in these cells remains elusive. We have over-expressed SKI to define its intrinsic role in hematopoiesis and myeloid neoplasms, which resulted in a robust competitive advantage upon transplantation, a complete dominance of the stem and progenitor compar
