description: The Centre for Advanced Laser Applications (CALA) in Garching near Munich features the ATLAS 3000 laser system, which can deliver up to 3\,PW within a pulse length of 20\,fs. It is the driver for the Laser-driven ION (LION) beamline, which aims to accelerate protons and carbons for applications. For commissioning, we currently operate with 5\,J on target in 28\,fs. A $20\degree$ off-axis parabolic mirror focuses the 28\,cm diameter laser-beam down to a micrometer-sized spot, where a vacuum-compatible wave-front sensor is used in combination with a deformable mirror for focus optimization. The nano-Foil Target Positioning System (nFTPS) can replace targets with a repetition rate of up to 0.5\,Hz and store up to 19 different target foils. A dipole magnet in a wide-angle spectrometer configuration deflects ions onto a CMOS detector for an online read-out. Commissioning started mid 2019 with regular proton acceleration using nm-thin plastic foils as targets. Since then proton cut-off energies above 20\,MeV have been regularly achieved. The amount of light traveling backwards from the experiment into the laser is constantly monitored and 5\,J on target have been determined as the current limit to prevent damage in the laser. Protons with a kinetic energy of 12\,MeV are stably accelerated with the given laser parameters and are suitable for transport with permanent magnet quadrupoles towards our application platform. We have performed parameter scans varying target thicknesses to optimize for highest and most stable proton numbers at 12\,MeV kinetic energy, and investigated shot-to-shot particle number stability for the best parameters.

Nonparametric tests of regularity conditions for production and consumption theory
Creators: name: Parkan, Celik
Publisher: name: University of British Columbia
Year: 2010

description: The theories of production and consumption have proven to be valuable tools in predicting variations in demand for factors of production (producer's demand) and for produced goods (consumer's demand) to changes in policy instruments. An important direction of inquiry, in the theory of production, has been on determining the functional form of production; another one, in the theory of consumption, has been on the observed behaviour of the consumer and the computation of index numbers. Econometricians, in estimating a production function, have been using parametric estimation techniques which always require the choice of a functional form for the underlying production operation. Also the classical assumption about the consumer has been that any purchase is such as to give a maximum of utility for the money spent. It is well known that economic agents' (producers' and consumers') optimizing behaviour implies certain restrictions on derived supply and demand patterns; e.g., see P.A. Samuelson or J.R. Hicks. Typical functional forms, for production, often used in empirical applications are either unsuitable for modelling the demand for factors of production or they do not always satisfy the regularity conditions that cost minimizing or profit maximizing behaviour imposes. Neither have econometricians always checked whether these restrictions are consistent with the functional forms for demand and supply equations which they use in their applied econometric work. This dissertation studies the nonparametric methods for testing the consistency of observations on quantities, prices, profits, costs and appropriate combinations of these with such regularity conditions as monotonicity, quasi-concavity, concavity, homotheticity, and separability. The approach has been that of unifying the existing body of knowledge in using linear programming as the test instrument and making extensions especially to cover multiple production, separability properties and nonparametric index numbers. The theoretical work has been substantiated by empirical tests on actual data and the computer codes are presented to facilitate further research in related areas.
Asymptotic AdS String Solutions for Null Polygonal Wilson Loops in R^{1,2}

description: For the asymptotic string solution in AdS_3 which is represented by the AdS_3 Poincare coordinates and yields the planar multi-gluon scattering amplitude at strong coupling in arXiv:0904.0663, we express it by the AdS_4 Poincare coordinates and demonstrate that the hexagonal and octagonal Wilson loops surrounding the string surfaces take closed contours consisting of null vectors in R^{1,2} owing to the relations of Stokes matrices. For the tetragonal Wilson loop we construct a string solution characterized by two parameters by solving the auxiliary linear problems and demanding a reality condition, and analyze the asymptotic behavior of the solution in R^{1,2}. The freedoms of two parameters are related with some conformal SO(2,4) transformations.

description: The thesis present the Irish Water Quality Index (IEWQI) model for assessing transitional and coastal water quality in an effort to improve the method and develop a tool that can be used by environmental regulators to abate water pollution in Ireland. The developed model has been associated with the adoption of water quality standards formulated for coastal and transitional waterbodies according to the water framework directive legislation by the environmental regulator of Irish water. The developed model has five identical components: (i) an indicator selection technique for selecting the critical water quality indicator; (ii) a sub-index (SI) function for rescaling the information from various water quality indicators into a uniform scale; (iii) an indicators' weight method for estimating the weight values based on the relative significance of real-time information on water quality; and (iv) an aggregation function for computing the water quality index. In the thesis, each model component, model performance assessment techniques and results (uncertainty, sensitivity, and efficiency), along applications are presented in detail in ten chapters: Chapter 1 presenting the research background, aims, and objectives, as well as a brief summary of the methodology used. Chapter 2 presents a comprehensive literature review of existing WQI models. Chapter 3 presents an improved WQI model for coastal water assessment. Chapter 4 describes a novel approach for estimating and predicting uncertainty in a WQI model. Chapter 5 presents a novel approach for model performance analysis. Chapter 6 presents optimising techniques for selecting model input. Chapter 7 presents a sophisticated model for rating water quality. Chapter 8 presents a robust ML/AI model for predicting water quality. Chapter 9 provides in details of the assessment trophic status index (ATSI) model; and finally Chapter 10 presents the summary, key conclusions from the research and recommendations.

description: Purpose: Mitral valve repair is a complex minimally invasive surgery of the heart valve. In this context, suture detection from endoscopic images is a highly relevant task that provides quantitative information to analyse suturing patterns, assess prosthetic configurations and produce augmented reality visualisations. Facial or anatomical landmark detection tasks typically contain a fixed number of landmarks, and use regression or fixed heatmap-based approaches to localize the landmarks. However in endoscopy, there are a varying number of sutures in every image, and the sutures may occur at any location in the annulus, as they are not semantically unique. Method: In this work, we formulate the suture detection task as a multi-instance deep heatmap regression problem, to identify entry and exit points of sutures. We extend our previous work, and introduce the novel use of a 2D Gaussian layer followed by a differentiable 2D spatial Soft-Argmax layer to function as a local non-maximum suppression. Results: We present extensive experiments with multiple heatmap distribution functions and two variants of the proposed model. In the intra-operative domain, Variant 1 showed a mean F1 of +0.0422 over the baseline. Similarly, in the simulator domain, Variant 1 showed a mean F1 of +0.0865 over the baseline. Conclusion: The proposed model shows an improvement over the baseline in the intra-operative and the simulator domains.

Trigonometrically extended Cornell potential and deconfinement

Year: 2008
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Non-perturbative methods of effective field theory such like Lattice QCD have allowed to establish connection between the QCD Lagrangian and quark potential models, a prominent outcome being the Cornell (linear plus Coulomb) potential. In being quite successful in explaining properties of heavy flavor hadrons, be them quarkonia or baryons, this potential has been found less spectacular in the description of the non-strange baryons, the nucleon and the Delta. This behavior indicates that the one-gluon exchange and the flux-tube interaction do not fully account for the complexity of the dynamics of three light quarks. Very recently, the Cornell potential which is of infinte range has been upgraded by us toward an exactly solvable trigonometric potential of finite range that interpolates between the inverse-distance potential and the infinite wells while passing through a region of linear growth, a reason for which it contains the inverse distance and the linear potentials as first terms in its Taylor series decomposition. We here first make the point that the upgraded Cornell potential can be viewed as the exact counterpart on a curved space to a flat space 1/r potential, a circumstance that equips it by two simultaneous symmetries, SO(4), and SO(2,1). These allow to place the trigonometric confinement potential in the context of AdS_5/CFT correspondence and thus to establish the link of the algebraic aspects of the latter to QCD potentiology. Next we report that the above potential when employed in the quark-diquark system, provides a remarkably adequate description of both nucleon and Delta spectra and the proton mean square charge radius as well, and moreover implies an intriguing venue toward quark deconfinement as shut-down of the curvature considered as temperature dependent.

description: At ambient pressure CaFe2As2 has been found to undergo a first order phase transition from a high temperature, tetragonal phase to a low temperature orthorhombic / antiferromagnetic phase upon cooling through T ~ 170 K. With the application of pressure this phase transition is rapidly suppressed and by ~ 0.35 GPa it is replaced by a first order phase transition to a low temperature collapsed tetragonal, non-magnetic phase. Further application of pressure leads to an increase of the tetragonal to collapsed tetragonal phase transition temperature, with it crossing room temperature by ~ 1.7 GPa. Given the exceptionally large and anisotropic change in unit cell dimensions associated with the collapsed tetragonal phase, the state of the pressure medium (liquid or solid) at the transition temperature has profound effects on the low temperature state of the sample. For He-gas cells the pressure is as close to hydrostatic as possible and the transitions are sharp and the sample appears to be single phase at low temperatures. For liquid media cells at temperatures below media freezing, the CaFe2As2 transforms when it is encased by a frozen media and enters into a low temperature multi-crystallographic-phase state, leading to what appears to be a strain stabilized superconducting state at low temperatures.

description: We show coincidence of the two definitions of the integrated density of states (IDS) for a class of relativistic Schroedinger operators with magnetic fields and scalar potentials, the first one relying on the eigenvalue counting function of operators induced on open bounded sets with Dirichlet boundary conditions, the other one involving the spectral projections of the operator defined on the entire space. In this way one generalizes previous results for non-relativistic operators. The proofs needs the magnetic pseudodifferential calculus, as well as a Feynman-Kac-Ito formula for Levy processes. In addition, in case when both the magnetic field and the scalar potential are periodic, one also proves the existence of the IDS.

description: We explore the feasibility and astrophysical consequences of a new long-range U(1) gauge field ("dark electromagnetism") that couples only to dark matter, not to the Standard Model. The dark matter consists of an equal number of positive and negative charges under the new force, but annihilations are suppressed if the dark matter mass is sufficiently high and the dark fine-structure constant $\hatα$ is sufficiently small. The correct relic abundance can be obtained if the dark matter also couples to the conventional weak interactions, and we verify that this is consistent with particle-physics constraints. The primary limit on $\hatα$ comes from the demand that the dark matter be effectively collisionless in galactic dynamics, which implies $\hatα\lesssim 10^{-4}$ for TeV-scale dark matter. These values are easily compatible with constraints from structure formation and primordial nucleosynthesis. We raise the prospect of interesting new plasma effects in dark matter dynamics, which remain to be explored.

Diffusing proteins on a fluctuating membrane: Analytical theory and simulations

description: Using analytical calculations and computer simulations we consider both the lateral diffusion of a membrane protein and the fluctuation spectrum of the membrane in which the protein is embedded. The membrane protein interacts with the membrane shape through its spontaneous curvature and bending rigidity. The lateral motion of the protein may be viewed as diffusion in an effective potential, hence, the effective mobility is always reduced compared to the case of free diffusion. Using a rigorous path-integral approach we derive an analytical expression for the effective diffusion coefficient for small ratios of temperature and bending rigidity, which is the biologically relevant limit. Simulations show very good quantitative agreement with our analytical result. The analysis of the correlation functions contributing to the diffusion coefficient shows that the correlations between the stochastic force of the protein and the response in the membrane shape are responsible for the reduction. Our quantitative analysis of the membrane height correlation spectrum shows an influence of the protein-membrane interaction causing a distinctly altered wave-vector dependence compared to a free membrane. Furthermore, the time correlations exhibit the two relevant timescales of the system: that of membrane fluctuations and that of lateral protein diffusion with the latter typically much longer than the former. We argue that the analysis of the long-time decay of membrane height correlations can thus provide a new means to determine the effective diffusion coefficient of proteins in the membrane.

description: We present the first results from the SuperWASP Variable Stars (SVS) citizen science project. The photometry archive of the Wide Angle Search for Planets has previously been searched for periodic variations and the results of this search formed the basis of the SVS project on the Zooniverse. The SVS project asks volunteers to visually inspect light curve plots and categorize each one according to a broad classification scheme. Results from the first two years of SVS have now been published online as the SuperWASP Variable Star Photometry Archive (VeSPA). The archive can be browsed online, downloaded in full, or queried, filtered, and sorted to export a refined set of results. An interactive light curve viewer also allows any light curve to be folded at a user-defined period. Analysis of citizen science results and development of VeSPA features are both ongoing. Updated results will be published every six months.

description: The positive mass theorem in general relativity states that in an asymptotically flat spacetime, if the momentum--energy tensor is divergence-free and satisfies a dominant energy condition, then a total momentum--energy four-vector can be formed, of which the energy component is nonnegative. In this paper, we take the wave four-tensor of a plane light wave in free space as a counterexample to show that there is no guarantee that a total four-vector can be formed. Thus the theoretical framework for the positive mass theorem is flawed. In addition, it is also shown as well that the Lorentz covariance of Dirac wave equation is not compatible with Einstein mass--energy equivalence.

description: Multi-wavelength observations of a sigmoidal (S-shaped) solar coronal source by the EUV Imaging Spectrometer and the X-ray Telescope aboard the Hinode spacecraft and by the EUV Imager aboard STEREO are reported. The data reveal the coexistence of a pair of J-shaped hot arcs at temperatures T>2 MK with an S-shaped structure at somewhat lower temperatures T~1.3 MK. The middle section of the S-shaped structure runs along the polarity inversion line of the photospheric field, bridging the gap between the arcs. Flux cancellation occurs at the same location in the photosphere. The sigmoid forms in the gradual decay phase of the active region, which does not experience an eruption. These findings correspond to the expected signatures of a flux rope forming, or being augmented, gradually by a topology transformation inside a magnetic arcade. In such a transformation, the plasma on newly formed helical field lines in the outer flux shell of the rope (S-shaped in projection) is expected to enter a cooling phase once the reconnection of their parent field line pairs (double-J shaped in projection) is complete. Thus, the data support the conjecture that flux ropes can exist in the corona prior to eruptive activity.

description: Quality improvement methods are essential to gathering high-quality crowdsourced data, both for research and industry applications. A popular and broadly applicable method is task assignment that dynamically adjusts crowd workflow parameters. In this survey, we review task assignment methods that address: heterogeneous task assignment, question assignment, and plurality problems in crowdsourcing. We discuss and contrast how these methods estimate worker performance, and highlight potential challenges in their implementation. Finally, we discuss future research directions for task assignment methods, and how crowdsourcing platforms and other stakeholders can benefit from them.

description: This study tackles on a new problem of estimating human-error potential on a shop floor on the basis of wearable sensors. Unlike existing studies that utilize biometric sensing technology to estimate people's internal state such as fatigue and mental stress, we attempt to estimate the human-error potential in a situation where a target person does not stay calm, which is much more difficult as sensor noise significantly increases. We propose a novel formulation, in which the human-error-potential estimation problem is reduced to a classification problem, and introduce a new method that can be used for solving the classification problem even with noisy sensing data. The key ideas are to model the process of calculating biometric indices probabilistically so that the prior knowledge on the biometric indices can be integrated, and to utilize the features that represent the movement of target persons in combination with biometric features. The experimental analysis showed that our method effectively estimates the human-error potential.

description: We apply a Monte-Carlo method to the two flavor Polyakov loop extended Nambu and Jona-Lasinio (PNJL) model. In such a way we can go beyond mean field calculations introducing fluctuations of the fields. We study the impact of fluctuations on the thermodynamics of the model. We calculate the second derivatives of the thermodynamic grand canonical partition function with respect to the chemical potential and present a comparison with lattice data also for flavor non-diagonal susceptibilities.

description: Carbon nanoscrolls (CNSs) are structures formed by rolling up graphene layers into a papyruslike shape. CNNs have been experimentally produced by different groups. Boron nitride nanoscrolls (BNNSs) are similar structures using boron nitride instead of graphene layers. In this work we report molecular mechanics and molecular dynamics results for the structural and dynamical aspects of BNNS formation. Similarly to CNS, BNNS formation is dominated by two major energy contributions, the increase in the elastic energy and the energetic gain due to van der Waals interactions of the overlapping surface of the rolled layers. The armchair scrolls are the most stable configuration while zigzag scrolls are metastable structures which can be thermally converted to armchair. Chiral scrolls are unstable and tend to evolve to zigzag or armchair configurations depending on their initial geometries. The possible experimental routes to produce BNNSs are also addressed.

description: Having accurate completeness functions is crucial to the determination of the rest-frame ultraviolet luminosity functions (UVLFs) all the way back to the epoch of reionization. Most studies use injection-recovery simulations to determine completeness functions. Although conceptually similar, published approaches have subtle but important differences in their definition of the completeness function. As a result, they implement different methods to determine the UVLFs. We discuss the advantages and limitations of existing methods using a set of mock observations, and then compare the methods when applied to the same set of Hubble Legacy Field (HLF) images. We find that the most robust method under all our mock observations is the one that defines completeness as a function of both input and output magnitude. Other methods considering completeness only as a function of either input or output magnitude may suffer limitations in a presence of photometric scatter and/or steep luminosity functions. In particular, when the flux scatter is >0.2 mag, the bias in the bright end of the UVLFs is on par with other systematic effects such as the lensing magnification bias. When tested on HLF images, all methods yield UVLFs that are consistent within 2 sigma confidence, suggesting that UVLF uncertainties in the literature are still dominated by small number statistics and cosmic variance. The completeness simulation code used in this study (GLACiaR2) is publicly released with this paper as a tool to analyze future higher precision datasets such as those expected from the James Webb Space Telescope.

description: From the psychological point of view hearing is an essential sensory modality for the human species, because it contributes to the formation of the first relational connections and emotions. It is important to make a diagnosis early to intervene and limit negative effects.  Deafness is a particular phenomenon (onset, types),  in this paper we undertake a thorough descriptive analysis on all aspects of deafness, in particular the use of a prosthetic device known as cochlear implant.  We have deepened personality variables in a single case with the use of Rorschach Test and Draw-a-person-Test.  We aimed to study, with the clinical interpretation of instruments, which personality variables could be involved in hearing loss condition and Cochlear Implant (CI).  This observational study highlights the psychological dynamics that should be taken into account by operators team, in order to improve the quality of life of these patients and increase their long-term therapeutic outcome.

description: Abstract
Background: Despite the role of metacognition in psychopathology, no studies have explored this construct in the area of gastrointestinal disorders. Moreover, for many times there was a categorization between organic and functional gastrointestinal disorders. The aim of this study was to compare dysfunctional metacognitive beliefs between patients with functional bowel disorders and patients with organic bowel disorders. The purpose of this work was also to examine the relations between metacognitions, alexithymia and symptoms of the patients on the basis of diagnosis.
Methods: A between-subject non parametric and correlational design was employed. We formed three clinical groups from a population of patients with gastrointestinal disorders and on the basis of the ‘organic’ and ‘functional’ diagnosis. All the participants underwent the Metacognitions Questionnaire 30, the Toronto Alexithymia Scale-20 and the Gastrointestinal Symptom Rating Scale.
Results: There were no significant differences between the three clinical groups on MCQ-30 and TAS-20 scores. However, there were significant correlations based on diagnosis of the gastrointestinal disorder between alexithymic features and metacognitive dysfunctional beliefs.
Conclusions: Our results underline the role of metacognitions for both patients with organic and functional gastrointestinal disorders. Moreover, the results highlight the importance to consider these aspects in patients with organic gastrointestinal disorder.
