Electromagnetic design of a new axial and radial flux generator with the rotor back irons

The design and simulation of a new three phase axial flux generator have been performed. The generator is a permanent magnet machine (PMG) and consists of two rotors at two sides and a stator at the middle. In the machine, each rotor has 16 rare earth disc type magnets and back iron units and the stator at the middle has 24 coils. It has been understood that the generator produces directly sinusoidal output and requires no conversion in the wave shape. The 3D simulations have been performed via the finite element analysis (FEA) method by the magnetostatic and magnetodynamic tools. It has been found that the machine generates 3.4 kW at 1000 rpm for the air gap of 1.5 mm. This gives the power density of 336 kW/m 3 for the rated value of the generator and it is higher than the power densities of many axial flux generators in the literature. The maximal cogging torque value has been estimated as 3.6 Nm, which is a good value for a back iron machine. It has been also proven that the waveform harmonics become lower at higher rotor speeds.
Force Amplifying N robot Transport System (Force ANTS) for cooperative planar manipulation without communication
Venue: Int. J. Robotics Res.

We propose the concept of a Force Amplifying N robot Transport System (Force ANTS) to coordinate the manipulation forces from a group of robots in order to transport a heavy object in a planar environment. Our approach requires no explicit communication among robots. Instead, we prove that robots can use local measurements of the object's motion at their attachment points as implicit information for force coordination. A leader (either a robot or human) can guide the whole group towards the destination by applying a relatively small force, whose effect is amplified by the follower robots as they align their forces with the leader's. Two Force ANTS implementations are introduced and analyzed, accounting for two different classes of object dynamics: small objects where kinetic friction dominates, and large objects where inertia and viscous friction dominate. Our approach can be used as a modular system for transporting heavy objects of various sizes in many real life applications. Simulations with up to 1000 robots and experiments using four custom built robots are conducted to validate our approach. We also conduct human robot cooperation experiments where the human force is amplified by three follower robots.
Crowd sourcing tools within the PREPARE analytical platform

A brief overview of the crowd sourcing tools developed within the analytical platform of the PREPARE project is presented. Crowd sourcing relates to methods that: offer a Web Content Discovery Service that automatically acquires and analyses content from social networks and the Web to extract information during nuclear or radiological (NR) events as well as the public opinion and perspective regarding an event occurrence and development; support an Ask the Expert Service for the public to have access to information relevant to NR events. Crowd sourcing provides the means to enhance the relevance and quality of publicly available information that is to be distributed through the analytical platform. To that end, processes have been formulated to collect: Web content relevant to a NR event and analyse it for trend identification regarding public opinions and concerns expressed in Web forums. Large scale content acquisition and text analytics for Web forum monitoring within social networks provides results at a scale that cannot be manually achieved; feedback from the user interaction with the system and analyse it to identify documents of interest and relevance to the queries posed.
Who Pays to Play Freemium Games? The Profiles and Motivations of Players Who Make Purchases Within Social Casino Games
Venue: Journal of behavioral addictions

Social casino games (SCGs) feature gambling themes and are typically free to download and play with optional in game purchases. Although few players spend money, this is sufficient to make them profitable for game developers. Little is known about the profile and motivations of paying players as compared to non paying players.  This study compared the characteristics of 521 paying and non paying Australian social casino game players who completed an online survey.  Paying players were more likely to be younger, male, speak a non English language, and have a university education than non payers. Paying players were more likely to be more highly involved in SCG in terms of play frequency and engagement with games and emphasized social interaction more strongly as a motivation for playing. A cluster analysis revealed distinct subgroups of paying players; these included more frequent moderate spenders who made purchases to avoid waiting for credits and to give gifts to friends as well as less frequent high spenders who made purchases to increase the entertainment value of the game.  These findings suggest that paying players have some fundamental differences from non paying players and high spenders are trying to maximize their enjoyment, while non spenders are content with the game content they access.  Given the structural similarities between SCG and online gambling, understanding subgroups of players may have broader implications, including identifying characteristics of gamers who may also engage in gambling and players who may develop problems related to excessive online gaming.
Prevalence of bullying, discrimination and sexual harassment among trainees and Fellows of the College of Intensive Care Medicine of Australia and New Zealand.
Venue: Critical care and resuscitation journal of the Australasian Academy of Critical Care Medicine

Anecdotal reports about bullying behaviour in intensive care emerged during College of Intensive Care Medicine (CICM) hospital accreditation visits. Bullying, discrimination and sexual harassment (BDSH) in the medical profession, particularly in surgery, were widely reported in the media recently. This prompted the College to formally survey its Fellows and trainees to identify the prevalence of these behaviours in the intensive care workplace.  An online survey of all trainees (n 951) and Fellows (n 970) of the CICM.  The survey response rate was 51% (Fellows, 60% trainees, 41% The overall prevalences of bullying, discrimination and sexual harassment were 32% 12% and 3% respectively. The proportions of Fellows and trainees who reported being bullied and discriminated against were similar across all age groups. Women reported a greater prevalence of sexual harassment (odds ratio [OR] 2.97 [95% CI, 1.35 6.51] P 0.006) and discrimination (OR, 2.10 [95% CI, 1.39 3.17] P 0.0004) than men. Respondents who obtained their primary medical qualification in Asia or Africa appeared to have been at increased risk of discrimination (OR, 1.88 [95% CI, 1.15 3.05] P 0.03) Respondents who obtained their degree in Australia, New Zealand or Hong Kong may have been at increased risk of being bullied. In all three domains of unprofessional behaviour, the perpetrators were predominantly consultants (70% overall) and the highest proportion of these was ICU consultants.  The occurrence of BDSH appears to be common in the intensive care environment in Australia and New Zealand.

A recent survey of trainees and Fellows of the College of Intensive Care Medicine of Australia and New Zealand (CICM) identifi ed that bullying, discrimination and sexual harassment (BDSH) appear to be common in the intensive care unit environment in Australia and New Zealand. The reported prevalence of each was: bullying, 32% discrimination, 12% and sexual harassment, 3% These experiences were reported by trainees and Fellows across all age groups. The fi ndings of the survey were presented at the 2016 CICM annual scientifi c meeting in Adelaide and are published in this issue of Critical Care and Resuscitation, the journal of the College.
Structural, magnetic, and Mossbauer spectroscopy of Cu substituted M type hexaferrites

Cu x O 19 hexaferrites were prepared using ball milling and sintering at 1100 degC. Refinement of the X ray diffraction patterns was carried out to determine the structural parameters and the ionic distribution over the crystallographic sites. The preferential site occupation and valence state of Cu was consistent with the results obtained from the analysis of Mossbauer spectra. Further, the magnetic parameters of the samples were discussed in light of the structural and Mossbauer analyses. The magnetic phase transition temperature was found to decrease with the level of Cu substitution, in accordance with the reduction of the superexchange interactions. Further, the magnetic softening of the hexaferrite and the significant reduction in magnetocrystalline anisotropy with Cu substitution was consistent with the ionic distribution in the lattice. This study clearly demonstrated the feasibility of using a simple method to fabricate hexaferrites with a modified coercivity, while maintain the saturation magnetization high enough for practical applications.
Mossbauer Spectroscopy of Iron Carbides: From Prediction to Experimental Confirmation
Venue: Scientific reports

The Mossbauer spectroscopy of iron carbides (a Fe, g' FeC, e Fe2C, z Fe2C, kh Fe5C2, h Fe7C3, th Fe3C, o Fe7C3, g' Fe4C, g' Fe4C, and a' Fe16C2) is predicted utilizing the all electron full potential linearized augmented plane wave (FLAPW) approach across various functionals from LDA to GGA (PBE, PBEsol, and GGA U) to meta GGA to hybrid functionals. To validate the predicted MES from different functionals, the single phase kh Fe5C2 and th Fe3C are synthesized in experiment and their experimental MES under different temperature (from 13 K to 298 K) are determined. The result indicates that the GGA functional (especially, the PBEsol) shows remarkable success on the prediction of Mossbauer spectroscopy of a Fe, kh Fe5C2 and th Fe3C with delocalized d electrons. From the reliable simulations, we propose a linear relationship between Bhf and mB with a slope of 12.81 T/mB for iron carbide systems and that the proportionality constant may vary from structure to structure.
Probing active sites in iron based catalysts for oxygen electro reduction: A temperature dependent 57Fe Mossbauer spectroscopy study

Two Fe N C electrocatalysts for oxygen reduction were studied by 57Fe Mossbauer spectroscopy between 300 and 5 K. The first catalyst contains almost exclusively FeNxCy moieties while the second contains additional crystalline phases, i.e. metallic iron and iron carbide. The Mossbauer parameters of two quadrupole doublets named D1 and D2, attributed to low and medium spin FeN4/C moieties, respectively, do not change with temperature down to 5 K. This indicates that such moieties do not undergo phase transition or magnetic ordering, supporting the view that the active sites are localized on isolated iron atoms. At room temperature, the Lamb Mossbauer factors of doublets D1 and D2 are 0.46 and 0.52, smaller than those of a Fe (0.67) and g Fe (0.78) These values allow for the first time a precise Mossbauer quantification of Fe species in Fe N C catalysts. The ORR activity is best correlated with the absolute content of the FeN4/C moiety associated with doublet D1, assigned to a FeIIN4/C moiety in low spin state. The ORR turnover frequency of such moieties is however known to depend on chemical and electronic properties of the carbon matrix, which will require additional descriptor(s) than the site density in order to precisely interpret the ORR activity of such materials.
Mossbauer spectroscopy with a high velocity resolution: Principles and applications

Principles and applications of Mossbauer spectroscopy with a high velocity resolution are considered. A comparison of the spectra quality measured using conventional and high velocity resolution Mossbauer spectrometers showed the possibility of the latter technique to fit much better the features of the absorption line shape. The limitations and problems of Mossbauer spectroscopy with a high velocity resolution are also discussed. Nevertheless, advances of this technique could be considered as a way to improve Mossbauer spectrometers and measure the high quality Mossbauer spectra permitting to excavate new results on the basis of a decrease of the instrumental (systematic) error for hyperfine parameters and better fit of the complex Mossbauer spectra.
No rationale for 1 variable per 10 events criterion for binary logistic regression analysis
Venue: BMC Medical Research Methodology

BackgroundTen events per variable (EPV) is a widely advocated minimal criterion for sample size considerations in logistic regression analysis. Of three previous simulation studies that examined this minimal EPV criterion only one supports the use of a minimum of 10 EPV. In this paper, we examine the reasons for substantial differences between these extensive simulation studies.MethodsThe current study uses Monte Carlo simulations to evaluate small sample bias, coverage of confidence intervals and mean square error of logit coefficients. Logistic regression models fitted by maximum likelihood and a modified estimation procedure, known as Firth's correction, are compared.ResultsThe results show that besides EPV, the problems associated with low EPV depend on other factors such as the total sample size. It is also demonstrated that simulation results can be dominated by even a few simulated data sets for which the prediction of the outcome by the covariates is perfect 'separation' We reveal that different approaches for identifying and handling separation leads to substantially different simulation results. We further show that Firth's correction can be used to improve the accuracy of regression coefficients and alleviate the problems associated with separation.ConclusionsThe current evidence supporting EPV rules for binary logistic regression is weak. Given our findings, there is an urgent need for new research to provide guidance for supporting sample size considerations for binary logistic regression analysis.
HEALER: homomorphic computation of ExAct Logistic rEgRession for secure rare disease variants analysis in GWAS
Venue: Bioinform.

Genome wide association studies (GWAS) have been widely used in discovering the association between genotypes and phenotypes. Human genome data contain valuable but highly sensitive information. Unprotected disclosure of such information might put individual's privacy at risk. It is important to protect human genome data. Exact logistic regression is a bias reduction method based on a penalized likelihood to discover rare variants that are associated with disease susceptibility. We propose the HEALER framework to facilitate secure rare variants analysis with a small sample size.  We target at the algorithm design aiming at reducing the computational and storage costs to learn a homomorphic exact logistic regression model (i.e. evaluate P values of coefficients) where the circuit depth is proportional to the logarithmic scale of data size. We evaluate the algorithm performance using rare Kawasaki Disease datasets.

The cystine/glutamate antiporter system xc drives breast tumor cell glutamate release and cancer induced bone pain
Venue: Pain

Bone is one of the leading sites of metastasis for frequently diagnosed malignancies, including those arising in the breast, prostate and lung. Although these cancers develop unnoticed and are painless in their primary sites, bone metastases result in debilitating pain. Deeper investigation of this pain may reveal etiology and lead to early cancer detection. Cancer induced bone pain (CIBP) is inadequately managed with current standard of care analgesics and dramatically diminishes patient quality of life. While CIBP etiology is multifaceted, elevated levels of glutamate, an excitatory neurotransmitter, in the bone tumor microenvironment may drive maladaptive nociceptive signaling. Here, we establish a relationship between the reactive nitrogen species peroxynitrite, tumor derived glutamate, and CIBP. In vitro and in a syngeneic in vivo model of breast CIBP, murine mammary adenocarcinoma cells significantly elevated glutamate via the cystine/glutamate antiporter system xc The well known system xc inhibitor sulfasalazine significantly reduced levels of glutamate and attenuated CIBP associated flinching and guarding behaviors. Peroxynitrite, a highly reactive species produced in tumors, significantly increased system xc functional expression and tumor cell glutamate release. Scavenging peroxynitrite with the iron and mangano based porphyrins, FeTMPyP and SRI10, significantly diminished tumor cell system xc functional expression, reduced femur glutamate levels and mitigated CIBP. In sum, we demonstrate how breast cancer bone metastases upregulate a cystine/glutamate co transporter to elevate extracellular glutamate. Pharmacological manipulation of peroxynitrite or system xc attenuates CIBP, supporting a role for tumor derived glutamate in CIBP and validating the targeting of system xc as a novel therapeutic strategy for the management of metastatic bone pain.
Angiotensin (1 7)/Mas receptor as an antinociceptive agent in cancer induced bone pain
Venue: Pain

Many cancerous solid tumors metastasize to the bone and induce pain (cancer induced bone pain [CIBP] Cancer induced bone pain is often severe because of enhanced inflammation, rapid bone degradation, and disease progression. Opioids are prescribed to manage this pain, but they may enhance bone loss and increase tumor proliferation, further compromising patient quality of life. Angiotensin (1 7) (Ang (1 7) binds and activates the Mas receptor (MasR) Angiotensin (1 7)/MasR activation modulates inflammatory signaling after acute tissue insult, yet no studies have investigated whether Ang (1 7)/MasR play a role in CIBP. We hypothesized that Ang (1 7) inhibits CIBP by targeting MasR in a murine model of breast CIBP. 66.1 breast cancer cells were implanted into the femur of BALB/cAnNHsd mice as a model of CIBP. Spontaneous and evoked pain behaviors were assessed before and after acute and chronic administration of Ang (1 7) Tissues were collected from animals for ex vivo analyses of MasR expression, tumor burden, and bone integrity. Cancer inoculation increased spontaneous pain behaviors by day 7 that were significantly reduced after a single injection of Ang (1 7) and after sustained administration. Preadministration of A 779 a selective MasR antagonist prevented this reduction, whereas pretreatment with the AT2 antagonist had no effect; an AT1 antagonist enhanced the antinociceptive activity of Ang (1 7) in CIBP. Repeated Ang (1 7) administration did not significantly change tumor burden or bone remodeling. Data here suggest that Ang (1 7)/MasR activation significantly attenuates CIBP, while lacking many side effects seen with opioids. Thus, Ang (1 7) may be an alternative therapeutic strategy for the nearly 90% of patients with advanced stage cancer who experience excruciating pain.
