description: We obtain the effective potential at finite temperature within the left-right symmetric model. We take the Higgs sector to consist of two doublets and calculate its finite temperature effective potential up to the order of ``ring-diagrams'', using analogous techniques to those employed in the derivation of the effective potential in the Standard Model. We find that two first order phase transitions can exist, one at the $SU(2)_R$ breaking scale, the other at the usual $SU(2)_L\otimes U(1)_Y$ breaking scale. Even though more parameters are present than the standard model, we find that the electroweak phase transition is still too weak to allow baryon asymmetry to survive the transition, if the lower bound of the Higgs boson mass from experiment is adhered to.

description: Einstein-Gauss-Bonnet-gravity (EGB) coupled minimally to a $U(1)$ gauged, massive scalar field possesses -- for appropriate choices of the $U(1)$ charge -- black hole solutions that carry charged scalar hair if the frequency of the harmonic time-dependence of the scalar field is equal to the upper bound on the superradiant frequency. The existence of these solutions has first been discussed in \cite{Grandi:2017zgz}. In this paper, we demonstrate that the critical value of the scalar charge results from the requirement of non-extremality of the charged black hole solutions and the fact that the scalar field should not escape to infinity. Moreover, we investigate the hairy black holes in more detail and demonstrate that the branch of these solutions joins the branch of the corresponding charged EGB black hole for vanishing scalar field, but is {\it not} connected to the branch of boson stars in the limit of vanishing horizon radius. This indicates that it is unlikely that these black holes appear from the collapse of the corresponding boson stars. Finally, we prove a No-hair theorem for charged scalar fields with harmonic time-dependence for static, spherically symmetric, asymptotically flat electro-vacuum black holes in $d$ space-time dimensions and hence demonstrate that the GB term is crucial for the existence of the hairy black holes discussed in this paper.

description: We show that the predicted hyperon masses in the topological soliton model are very sensitive to the value of the gluon condensate parameter that appears when the scale invariance and trace anomaly of QCD are taken into account by introduction of a dilaton field. This contrasts with the insensitivity of the soliton properties to the dilaton coupling. In order that the predicted strange and charmed hyperon spectra agree with the empirical ones the gluon condensate parameter has to be about (400 MeV)$^4$, which agrees with the result obtained from QCD sum rules. This implies that the bag formed by the scalar field must be very shallow.

description: Anthocyanins exhibit natural antioxidants but exhibit poor stability and low oil solubility. Therefore, increasing the stability and fat solubility of anthocyanins is necessary to broaden their applications. In our experiment, an anthocyanin microemulsion system was constructed and its stability was investigated. At an oil phase and emulsifier ratio of 7:3, the hydrophilic oil-wet value reached 7.5 and the Km was 2:1. Furthermore, the microemulsion area was the largest. The bicontinuous region of the microemulsion exhibited optimal experimental conditions and resulted in a microemulsion containing 425.54 ± 1.58 μg/g anthocyanins. The anthocyanin microemulsion was a water-in-oil type, with a particle size of 0.07 ± 0.009 μm. Moreover, the temperature, light, and sample observation tests showed that the anthocyanin retention rate in the microemulsion was higher than that in the anthocyanin solution. Low-concentration NaCl and less than 9% of glucose and sucrose exerted no significant influence on the anthocyanin microemulsion stability.

description: Characterizing functional brain networks in humans during magnetophosphene perception. Dense electroencephalography (EEG, 128 channels) was performed in N=3 volunteers during high-level (50 mT) magnetic field (MF) exposure. Functional brain networks were reconstructed, at the cortical level from scalp recordings, using the EEG source connectivity method. Magnetophosphene perception appears to consistently activate the right inferior occipito-temporal pathway. This study provides the very first neuroimaging results characterizing magnetophosphene perception in humans. The use of dense-EEG source connectivity is a promising approach in the field of bioelectromagnetics.

Apparent wave function collapse caused by scattering

description: Some experimental implications of the recent progress on wave function collapse are calculated. Exact results are derived for the center-of-mass wave function collapse caused by random scatterings and applied to a range of specific examples. The results show that recently proposed experiments to measure the GRW effect are likely to fail, since the effect of naturally occurring scatterings is of the same form as the GRW effect but generally much stronger. The same goes for attempts to measure the collapse caused by quantum gravity as suggested by Hawking and others. The results also indicate that macroscopic systems tend to be found in states with (Delta-x)(Delta-p) = hbar/sqrt(2), but microscopic systems in highly tiltedly squeezed states with (Delta-x)(Delta-p) >> hbar.

description: © 2018, Springer Science+Business Media B.V., part of Springer Nature. Educators have struggled to incorporate authentic team-based learning (TBL) into the business curriculum despite increasing evidence that collaborative learning can enhance learning outcomes. We investigate the use of online business simulations as a platform for fostering authentic TBL for undergraduate and postgraduate business students studying at seven institutions in Australia and Hong Kong. Quantitative analysis of 365 surveys is supported by focus groups with 14 students. Structural equation modeling (SEM) is used to model the relationships between teamwork, learning outcomes, and satisfaction. Qualitative results support the statistical modeling and are presented to add further insights and conceptual richness. The findings support our proposition that online business simulations provide an authentic TBL environment, which contributes to learner satisfaction by supporting the development of management-related learning outcomes through socially constructed meaning. This conceptual contribution highlights further avenues for research and leads to some practical implications for educators using simulation-based pedagogies.

description: Probabilistic linear discriminant analysis (PLDA) is a method used for biometric problems like speaker or face recognition that models the variability of the samples using two latent variables, one that depends on the class of the sample and another one that is assumed independent across samples and models the within-class variability. In this work, we propose a generalization of PLDA that enables joint modeling of two sample-dependent factors: the class of interest and a nuisance condition. The approach does not change the basic form of PLDA but rather modifies the training procedure to consider the dependency across samples of the latent variable that models within-class variability. While the identity of the nuisance condition is needed during training, it is not needed during testing since we propose a scoring procedure that marginalizes over the corresponding latent variable. We show results on a multilingual speaker-verification task, where the language spoken is considered a nuisance condition. We show that the proposed joint PLDA approach leads to significant performance gains in this task for two different datasets, in particular when the training data contains mostly or only monolingual speakers.

description: We investigate the random walk of prices by developing a simple model relating the properties of the signs and absolute values of individual price changes to the diffusion rate (volatility) of prices at longer time scales. We show that this benchmark model is unable to reproduce the diffusion properties of real prices. Specifically, we find that for one hour intervals this model consistently over-predicts the volatility of real price series by about 70%, and that this effect becomes stronger as the length of the intervals increases. By selectively shuffling some components of the data while preserving others we are able to show that this discrepancy is caused by a subtle but long-range non-contemporaneous correlation between the signs and sizes of individual returns. We conjecture that this is related to the long-memory of transaction signs and the need to enforce market efficiency.

description: Early-type magnetic stars are rarely found in close binary systems. No such objects were known in eclipsing binaries prior to this study. Here we investigated the eclipsing, spectroscopic double-lined binary HD66051, which exhibits out-of-eclipse photometric variations suggestive of surface brightness inhomogeneities typical of early-type magnetic stars. Using a new set of high-resolution spectropolarimetric observations, we discovered a weak magnetic field on the primary and found intrinsic, element-dependent variability in its spectral lines. The magnetic field structure of the primary is dominated by a nearly axisymmetric dipolar component with a polar field strength $B_{\rm d}\approx600$ G and an inclination with respect to the rotation axis of $β_{\rm d}=13^{\rm o}$. A weaker quadrupolar component is also likely to be present. We combined the radial velocity measurements derived from our spectra with archival optical photometry to determine fundamental masses (3.16 and 1.75 $M_\odot$) and radii (2.78 and 1.39 $R_\odot$) with a 1-3% precision. We also obtained a refined estimate of the effective temperatures (13000 and 9000 K) and studied chemical abundances for both components with the help of disentangled spectra. We demonstrate that the primary component of HD66051 is a typical late-B magnetic chemically peculiar star with a non-uniform surface chemical abundance distribution. It is not an HgMn-type star as suggested by recent studies. The secondary is a metallic-line star showing neither a strong, global magnetic field nor intrinsic spectral variability. Fundamental parameters provided by our work for this interesting system open unique possibilities for probing interior structure, studying atomic diffusion, and constraining binary star evolution.

description: We present results from a four frequency observation of a 6 x 0.6 degree strip of the sky centered near the star Gamma Ursae Minoris during the fourth flight of the Millimeter-wave Anisotropy eXperiment (MAX). The observation was made with a 1.4 degree peak-to-peak sinusoidal chop in all bands. The FWHM beam sizes were 0.55 +/- 0.05 degrees at 3.5 cm-1 and 0.75 +/-0.05 degrees at 6, 9, and 14 cm-1. During this observation significant correlated structure was observed at 3.5, 6 and 9 cm-1 with amplitudes similar to those observed in the GUM region during the second and third flights of MAX. The frequency spectrum is consistent with CMB and inconsistent with thermal emission from interstellar dust. The extrapolated amplitudes of synchrotron and free-free emission are too small to account for the amplitude of the observed structure. If all of the structure is attributed to CMB anisotropy with a Gaussian autocorrelation function and a coherence angle of 25', then the most probable values of DeltaT/TCMB in the 3.5, 6, and 9 cm-1 bands are 4.3 (+2.7, -1.6) x 10-5, 2.8 (+4.3, -1.1) x 10-5, and 3.5 (+3.0, -1.6) x 10-5 (95% confidence upper and lower limits), respectively.

Exploring the Relationship between Risk Assessment Tools and Sub-Epidermal Moisture Measurement
Creators: name: Molloy, Susan
Publisher: name: Royal College of Surgeons in Ireland
Year: 2019
Subjects: Uncategorized

description: Assessment of risk in the development of pressure ulcers is an essential tool to prevent and therefore, reduce the incidence of pressure damage. Pressure damage has been shown to be preventable in 95% of cases (Chan et al., 2009). The economic and social ramifications of pressure damage are vast. They can drastically impair quality of life and cause considerable suffering for the individual. Clinicians are advised to employ the use of a validated risk assessment tool in their practice to aid the prevention of pressure damage (EPUAP, 2014). There are over forty validated risk assessment tools being used across the world at present (Kottner et al., 2010). The questionable validity of these tools has been debated in current research. The purpose of this study was to determine the relationship between current risk assessment tools and a new method of risk assessment, sub-epidermal moisture measurement in an effort to determine which tool will provide the clinician with the most accurate assessment of risk. A quantitative, prospective, non-experimental design was used. The study found similar issues regarding predictive validity of risk assessment tools as seen in previous research. The limitations of these tools must be emphasized and caution practiced with their use. The study found promise in the use of sub-epidermal moisture measurement however further research is needed to confirm these results. This is clinically relevant as limitations can be seen in the current methods of risk assessment. If sub-epidermal moisture measurement can perform in clinical practice as it has in research, it could be a valuable tool to aid clinicians in reducing pressure ulcer incidence.
Goal-oriented adaptive surrogate construction for stochastic inversion

Publisher: name: arXiv
Year: 2018
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: Stochastic inverse problems are generally solved by some form of finite sampling of a space of uncertain parameters. For computationally expensive models, surrogate response surfaces are often employed to increase the number of samples used in approximating the solution. The result is generally a trade off in errors where the stochastic error is reduced at the cost of an increase in deterministic/discretization errors in the evaluation of the surrogate. Such stochastic errors pollute predictions based on the stochastic inverse. In this work, we formulate a method for adaptively creating a special class of surrogate response surfaces with this stochastic error in mind. Adjoint techniques are used to enhance the local approximation properties of the surrogate allowing the construction of a higher-level enhanced surrogate. Using these two levels of surrogates, appropriately derived local error indicators are computed and used to guide refinement of both levels of the surrogates. Three types of refinement strategies are presented and combined in an iterative adaptive surrogate construction algorithm. Numerical examples, including a complex vibroacoustics application, demonstrate how this adaptive strategy allows for accurate predictions under uncertainty for a much smaller computational cost than uniform refinement.
Dispersion engineering of mode-locked fibre lasers

Year: 2018
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: Mode-locked fibre lasers are important sources of ultrashort pulses, where stable pulse generation is achieved through a balance of periodic amplitude and phase evolutions. A range of distinct cavity pulse dynamics have been revealed, arising from the interplay between dispersion and nonlinearity in addition to dissipative processes such as filtering. This has led to the discovery of numerous novel operating regimes, offering significantly improved laser performance. In this Topical Review, we summarise the main steady-state pulse dynamics reported to date through cavity dispersion engineering, including average solitons, dispersion-managed solitons, dissipative solitons, giant-chirped pulses and similaritons. Characteristic features and the stabilisation mechanism of each regime are described, supported by numerical modelling, in addition to the typical performance and limitations. Opportunities for further pulse energy scaling are discussed, in addition to considering other recent advances including automated self-tuning cavities and fluoride-fibre-based mid-infrared mode-locked lasers.

description: We examine the effect of a threshold bias on the power spectrum and the bispectrum in an ensemble of numerical simulations (Gaussian initial perturbations with power law spectra P(k) \sim k^n, n=+1, 0, -1, -2) and compare our results with theoretical predictions. Our simulations are evolved sufficiently that on the scale where we apply the threshold the rms fluctuation has developed significantly into the nonlinear regime. Thus, predictions based on perturbation theory do not necessarily apply. Nevertheless, we find our results for the power spectrum, biased power simply amplified by a numerical factor, follow predicted trends, far beyond the regime where perturbation theory is expected to be valid. We find that the biased bispectrum continues to follow the so-called hierarchical form, with reduced three-point amplitude Q \approx 1 in the strongly nonlinear regime, independent of initial spectrum. In the quasi-linear perturbative regime the three-point amplitude depends on configuration shape, a behavior that is found to give useful information about the amount of bias without information about the unbiased matter distribution.

An exploration of the patient and family or carer experience of implementing the pressure ulcer prevention care bundle (known as SSKIN) within a regional quality improvement collaborative
Creators: name: Fleming, Emma
Publisher: name: Royal College of Surgeons in Ireland
Year: 2019
Subjects: Uncategorized

description: Introduction: Pressure ulcers (PUs) are common, costly and impact negatively on patients’ quality of life. Bearing this in mind, in Ireland, a regional quality improvement collaborative was established within the Health Service Executive entitled ‘Pressure Ulcers to Zero’, utilizing the SSKIN care bundle in pressure ulcer prevention. As the involvement of patient and family/carer is a central component of health care delivery, this study set out to explore the patient and family/carer experiences and involvement within the collaborative including use of the SSKIN care bundle.
Methods: A qualitative descriptive approach was adopted. Since there were 3 main healthcare settings involved in the collaborative (acute /specialist, residential and primary care), one unit from each of these settings was purposively selected to participate. Following ethical approval and written informed consent, data were collected over a 6 week period using semi-structured, one to one interviews with patients, and focus group interviews with family members/carers. Twenty five persons agreed to participate; 16 patients, with varying levels of dependency, and 9 family members/carers .
Results: Data were analysed using Colaizzi’s Framework, 6 main themes with corresponding subthemes emerged from the analysis: awareness, patient involvement, family/carer involvement, ‘prevention is better than cure’, ‘communication is key’ and resources in prevention.
Discussions: Both patients and family/carer had limited involvement in PU prevention within the collaborative. Further, a general lack of awareness of the SSKIN care bundle was identified with some confusion surrounding its acronym. Participants expressed the desire to be more involved in PU prevention and the collaborative processes, henceforth, empowering patients and family/carers through education and communication may increase their level of involvement. This has meaning for future collaboratives, where tools, such as acronyms and activities, for example the design and presentation of visual aids pertaining to the collaborative subject, require a patient as well as a professional focus.
Clinical Relevance: Educating patients and families/carers on PU prevention through utilization of the SSKIN care bundle may facilitate a greater willingness of the patient and family/carer to participate in PU prevention. Also informing and including them in collaborative activities may address quality care issues.

description: Recently, Eremin and Manske [1] presented a oneband Fermi-liquid theory for the in-plane magnetic anisotropy in untwinned high-Tc superconductor YBa2Cu3O6:85 (YBCO). They claimed that they found good agreement with inelastic neutron scattering (INS) spectra. In this Comment, we point out that their conclusion on this important problem may be questionable due to an error in logic about the orthorhombicity delta_0 characterizing the lattice structure of YBCO. In Ref. [1], a single band at delta_0>0 is proved to be in accordance with the angle resolved photoemission spectroscopy (ARPES) on untwinned YBCO. But in their Erratum in PRL[3], they admit that delta_0= -0.03 was used to fit the INS data. Hence publications [1,3] contain errors that we believe invalidate their approach.

Figure S1 a–c show measurements along the previous pass from 17:05 to 17:10 UT on 2018 February 20. This pass was made approximately 90 min before the pseudo-breakup, which occurred at 18:35 UT. A trough minimum was located at 67.6–67.9°N, which is highlighted by a vertical bar in magenta. The SAPS or latitudinally extended westward plasma flow had not yet been well developed, but eastward plasma flows can be identified at the trough minimum along with westward flows. d, e show measurements from the successive pass from 20:12 to 20:17 UT. A trough minimum, highlighted by a magenta bar, was found at 68.6°N, and the eastward plasma flow was localized sharply at the trough minimum in the predominant westward flow.

description: Topological metal/semimetals (TMs) have emerged as a new frontier in the field of quantum materials. A few two-dimensional (2D) boron sheets have been suggested as Dirac materials, however, to date TMs made of three-dimensional (3D) boron structures have not been found. Herein, by means of systematic first principles computations, we discovered that a rather stable 3D boron allotrope, namely 3D-alpha' boron, is a nodal-chain semimetal. In the momentum space, six nodal lines and rings contact each other and form a novel spindle nodal chain. This 3D-alpha' boron can be formed by stacking 2D wiggle alpha' boron sheets, which are also nodal-ring semimetals. In addition, our chemical bond analysis revealed that the topological properties of the 3D and 2D boron structures are related to the pi bonds between boron atoms, however, the bonding characteristics are different from those in the 2D and 3D carbon structures.

description: Many scenarios require a robot to be able to explore its 3D environment online without human supervision. This is especially relevant for inspection tasks and search and rescue missions. To solve this high-dimensional path planning problem, sampling-based exploration algorithms have proven successful. However, these do not necessarily scale well to larger environments or spaces with narrow openings. This paper presents a 3D exploration planner based on the principles of Next-Best Views (NBVs). In this approach, a Micro-Aerial Vehicle (MAV) equipped with a limited field-of-view depth sensor randomly samples its configuration space to find promising future viewpoints. In order to obtain high sampling efficiency, our planner maintains and uses a history of visited places, and locally optimizes the robot's orientation with respect to unobserved space. We evaluate our method in several simulated scenarios, and compare it against a state-of-the-art exploration algorithm. The experiments show substantial improvements in exploration time ($2\times$ faster), computation time, and path length, and advantages in handling difficult situations such as escaping dead-ends (up to $20\times$ faster). Finally, we validate the on-line capability of our algorithm on a computational constrained real world MAV.

description: We address the problem of estimating statistics of hidden units in a neural network using a method of analytic moment propagation. These statistics are useful for approximate whitening of the inputs in front of saturating non-linearities such as a sigmoid function. This is important for initialization of training and for reducing the accumulated scale and bias dependencies (compensating covariate shift), which presumably eases the learning. In batch normalization, which is currently a very widely applied technique, sample estimates of statistics of hidden units over a batch are used. The proposed estimation uses an analytic propagation of mean and variance of the training set through the network. The result depends on the network structure and its current weights but not on the specific batch input. The estimates are suitable for initialization and normalization, efficient to compute and independent of the batch size. The experimental verification well supports these claims. However, the method does not share the generalization properties of BN, to which our experiments give some additional insight.
$ΔL \ge 4$ processes

description: We discuss the experimental prospects for observing processes which violate lepton number ($ΔL$) in four units (or more). First, we reconsider neutrinoless quadruple beta decay, deriving a model independent and very conservative lower limit on its half-life of the order of $10^{41}$ ys for $^{150}$Nd. This renders quadruple beta decay unobservable for any feasible experiment. We then turn to a more general discussion of different possible low-energy processes with values of $ΔL \ge 4$. A simple operator analysis leads to rather pessimistic conclusions about the observability at low-energy experiments in all cases we study. However, the situation looks much brighter for accelerator experiments. For two example models with $ΔL=4$ and another one with $ΔL=5$, we show how the LHC or a hypothetical future pp-collider, such as the FCC, could probe multi-lepton number violating operators at the TeV scale.

description: We use a class of trial wave functions which are generalizations of gaussians to study single soliton approximate analytic solutions to the KdV equations. The variational parameters obey a Hamiltonian dynamics obtained from the Principle of Least Action. We get extremely accurate approximate single soliton solutions including their time dependence using this method.

Can we use routinely collected primary care medical records to quantify and explain variations in amputation rates across the UK?

description: Peripheral artery disease (PAD) and diabetes are the two primary risk factors for major lower extremity amputation (MLEA), commonly presenting together. These conditions can result in loss of blood flow to or feeling in the lower limbs causing necrosis, ulceration and infection. Without timely treatment, amputation may be necessary. With both diabetes and vascular disease highly prevalent in the population, monitoring of MLEA incidence is vital to establish performance of preventative measures. Regional variation in MLEA incidence is known to exist within the UK but is unexplained by secondary care health data. Quantifying incidence using primary care health data could aid in this explanation.This thesis firstly aimed to understand MLEA epidemiology by synthesising existing literature. Then went onto ascertain if MLEAs were well recorded in primary care health data. Next, incidence of MLEA over time in terms of morbidity and region was estimated using linked primary and secondary care data. Finally, this thesis investigated reasons for regional variation.Differences in methodology and inaccuracies in existing literature were found cause MLEA incidence estimate variation in the UK. Recording of MLEA in primary care data was poor compared to secondary care data; largely due to date discrepancies and re-recording. New investigations found MLEA incidence in England was highest for those with comorbid vascular disease and diabetes. MLEA incidence decreased in all regions over the study period and was highest in the North-East, North-West and South-West of England, the reasons for which were unexplained using these data. Variation between the remaining regions was partially explained by ethnicity distribution.Regional variation in England remains largely unexplained by primary and secondary care data. Subsequent investigations should explore regional differences in clinical provision and accessibility as the driving reason for regional variation in MLEA incidence rates in England and the UK.

description: We study periodic points for endomorphisms $σ$ of abelian varieties $A$ over algebraically closed fields of positive characteristic $p$. We show that the dynamical zeta function $ζ_σ$ of $σ$ is either rational or transcendental, the first case happening precisely when $σ^n-1$ is a separable isogeny for all $n$. We call this condition very inseparability and show it is equivalent to the action of $σ$ on the local $p$-torsion group scheme being nilpotent. The "false" zeta function $D_σ$, in which the number of fixed points of $σ^n$ is replaced by the degree of $σ^n-1$, is always a rational function. Let $1/Λ$ denote its largest real pole and assume no other pole or zero has the same absolute value. Then, using a general dichotomy result for power series proven by Royals and Ward in the appendix, we find that $ζ_σ(z)$ has a natural boundary at $|z|=1/Λ$ when $σ$ is not very inseparable. We introduce and study tame dynamics, ignoring orbits whose order is divisible by $p$. We construct a tame zeta function $ζ^*_σ$ that is always algebraic, and such that $ζ_σ$ factors into an infinite product of tame zeta functions. We briefly discuss functional equations. Finally, we study the length distribution of orbits and tame orbits. Orbits of very inseparable endomorphisms distribute like those of Axiom A systems with entropy $\log Λ$, but the orbit length distribution of not very inseparable endomorphisms is more erratic and similar to $S$-integer dynamical systems. We provide an expression for the prime orbit counting function in which the error term displays a power saving depending on the largest real part of a zero of $D_σ(Λ^{-s})$.

description: We have performed micromagnetic simulations to study the formation of skyrmions in ferromagnetic elements with different shapes having perpendicular anisotropy. The strength of Dzyaloshinskii-Moriya interaction (D) and uniaxial anisotropy (K) are varied to elucidate the regime in which skyrmion formation can take place. It is found that for a certain combination of D and K skyrmion formation does not happen. Further we also observed that for large D and small K values, finite size effect dominates which in turn hinders formation of typical N'eel (spherical) skyrmions. However the resulting magnetic phase is skyrmionic in nature and has different shape. We also have found that the shape of the magnetic nano element has a significant role in determining the final magnetic state in addition to the competing D and K values.
