Magnetic deformation of the white dwarf surface structure

Year: 2000
Subjects: subject: Astrophysics (astro-ph)

description: The influence of strong, large-scale magnetic fields on the structure and temperature distribution in white dwarf atmospheres is investigated. Magnetic fields may provide an additional component of pressure support, thus possibly inflating the atmosphere compared to the non-magnetic case. Since the magnetic forces are not isotropic, atmospheric properties may significantly deviate from spherical symmetry. In this paper the magnetohydrostatic equilibrium is calculated numerically in the radial direction for either for small deviations from different assumptions for the poloidal current distribution. We generally find indication that the scale height of the magnetic white dwarf atmosphere enlarges with magnetic field strength and/or poloidal current strength. This is in qualitative agreement with recent spectropolarimetric observations of Grw$+10\degr8247$. Quantitatively, we find for e.g. a mean surface poloidal field strength of 100 MG and a toroidal field strength of 2-10 MG an increase of scale height by a factor of 10. This is indicating that already a small deviation from the initial force-free dipolar magnetic field may lead to observable effects. We further propose the method of finite elements for the solution of the two-dimensional magnetohydrostatic equilibrium including radiation transport in the diffusive approximation. We present and discuss preliminary solutions, again indicating on an expansion of the magnetized atmosphere.

Superconformal R-charges and dyon multiplicities in N=2 gauge theories
Creators: name: Ritz, Adam
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: N=(2,2) theories in 1+1D exhibit a direct correspondence between the R-charges of chiral operators at a conformal point and the multiplicities of BPS kinks in a massive deformation, as shown by Cecotti and Vafa. We obtain an analogous relation in 3+1D for N=2 gauge theories that are massive perturbations of Argyres-Douglas fixed points, utilizing the geometric engineering approach to N=2 vacua within IIB string theory. In this case the scaling dimensions of a certain subset of chiral operators at the UV fixed point are related to the multiplicities of BPS dyons. When the Argyres-Douglas SCFT is realized at the root of a baryonic Higgs branch, this translation from 1+1D to 3+1D can be understood physically from the relation between the bulk dynamics and the N=(2,2) worldsheet dynamics of vortices in the baryonic Higgs phase. Under a relevant perturbation, the BPS kink multiplicity on the vortex worldsheet translates to that of the bulk dyonic states. The latter viewpoint suggests the 3+1D version of the Cecotti-Vafa relation may hold more generally, and simple tests provide evidence in favor of this for more generic choices of the baryonic root.

description: L’interrogativo di questo progetto di ricerca ruota attorno al fenomeno del bullismo e vuole indagare sulle possibili correlazioni che possono esistere con l’ambiente scolastico. La ricerca ha coinvolto diverse sedi del territorio e un campione di allievi pari a 645, nel primo biennio del ciclo di scuola media. Agli allievi è stato sottoposto un questionario già sperimentato con successo in British Columbia e adattato alla realtà ticinese, titolato Middle Years Development Instrument [MDI] che raccoglie informazioni su cinque aree tematiche che riguardano il benessere dei preadolescenti ticinesi, chiamati ad esprimere il loro parere in merito a: sviluppo delle competenze socio emotive, relazioni con famiglia, amici e altri adulti, esperienze scolastiche in cui vengono specificati clima di classe e bullismo, salute fisica e benessere emotivo ed, infine, tempo libero. L’indagine ha confermato il valore centrale che la scuola ha nella vita educativa dell’allievo, in quanto luogo di socializzazione e integrazione a tempo pieno, nonché di apprendimento per imitazione dei modelli di riferimento o degli esempi tra pari. È stato dimostrato quanto l’azione scolastica sulla prevenzione del bullismo, non segua ancora un disegno ben strutturato e forte sulla risoluzione dei problemi di aggressività, incentivando condizioni che favoriscano benessere e integrazione.

description: In this paper we address the optimization of the tactical planning for the Fast Moving Consumer Goods industry using an MILP model. Shelf-life restrictions are introduced into this model to prevent unnecessary waste and missed sales. Three methods for implementing shelf-life restriction are compared. In the direct method the age of each product is tracked. While this method can provide optimal solutions, it is computationally inefficient. In the indirect method, products are forced to leave inventory at the end of their shelf-life. For supply chains consisting of two or more storage echelons this method cannot guarantee optimality. Nevertheless, the solutions obtained with the indirect method were always within a few percent of optimality. Moreover, on average, the computational time was reduced by a factor 32 when using the indirect method instead of the direct method. Finally, the hybrid method models the product age directly in the first storage stage, while considering the shelf-life indirectly in the second stage. The hybrid method obtains near-optimal solutions and, on average, the computational time is reduced more than 5 times compared to the direct method. Cases of up to 25 SKUs were optimized using the direct method, up to 100 SKUs using the hybrid method, and up to 1000 SKUs using the indirect method.

description: The features of the $IV$ characteristics of metallic carbon nanotubes (m-NTs) in different experimental setups are studied using semi-classical Boltzmann transport equation together with the heat dissipation equation to account for significant thermal effects at high electric bias. Our model predicts that the shape of the m-NT characteristics is basically controlled by heat removal mechanisms. In particular we show that the onset of negative differential resistance in free standing nanotubes finds its origins in strong transport nonlinearities associated with poor heat removal unlike in substrate-supported nanotubes.

The Scottish Art Scene:  shrinking resources, growing networks
Creators: name: Savage, Blane
Publisher: name: Zenodo
Year: 2024

description: This thesis examines specific challenges faced by mature Scottish visual artists in building and maintaining acareer of sustainable practice during a time of austerity, Brexit and the Covid pandemic. Key components of this thesis will be teaching resources which include documentary-based interviews with nine mature Scottish visual artists, supported by the work of academic theorists which were useful in helping contextualize the relationship between these artists and the central social power structures of the Scottish ‘art world’. It will also include a review of the Scottish government’s developing cultural policy between 2015-20 and what impact it has on those artists lives.In identifying the key milestones of their careers, the Scottish artists interviewed noted the significance of mentors and sponsors help in developing their careers and the fluid and inconsistent relationships they have had with the formal art market. They utilised diverse portfolios to generate income and used their reputations and cultural capital, both offline and online, in supporting themselves through grant funding, social media engagement, online sales or collective artists’ mutual support networks. Those artists who were unwilling or unable to transfer their engagement with customers online really financially struggled during the pandemic. A number of female artists interviewed identified patterns of gender based discrimination that had impacted them during their careers.Given the impact on funding for artists in Scotland in the post-Brexit era, the limited findings also identify the possibility of benefits to a more integrated Scottish government, Creative Scotland and Local Authority strategic approach in cultural and artistic support and the need for key data on cultural spend particularly at local authority level to be disaggregated to make it more accessible in decision making processes (Scottish Government, 2019). It also highlights a need for the artists to expand their access to resources out with current limited funding routesand the potential value in looking further afield for additional funding support and new collaborative opportunities.

description: This work proposes Isogeometric Analysis as an alternative to classical finite elements for simulating electric machines. Through the spline-based Isogeometric discretization it is possible to parametrize the circular arcs exactly, thereby avoiding any geometrical error in the representation of the air gap where a high accuracy is mandatory. To increase the generality of the method, and to allow rotation, the rotor and the stator computational domains are constructed independently as multipatch entities. The two subdomains are then coupled using harmonic basis functions at the interface which gives rise to a saddle-point problem. The properties of Isogeometric Analysis combined with harmonic stator-rotor coupling are presented. The results and performance of the new approach are compared to the ones for a classical finite element method using a permanent magnet synchronous machine as an example.

description: Fine airborne particles (<10 µm) pose challenges for engineered systems, human health, and environmental pollution. This work investigates the relative influences of van der Waals and capillary adhesion forces during filtration to guide the design of multiplexed inertial coalescence filters, which are constructed with a parallel series of helical passageways designed for low pressure drop (<150 Pa) and capture of fine particulate matter (5–50 μm). Specifically, we experimentally quantified the influence of particle adhesion forces on filtration efficiency for capture of 6.1 µm activated carbon particle clusters. Filtration efficiency for dry filters, where van der Waals adhesion forces dominate, is significantly diminished beyond a threshold flowrate due to the Saffman lift force, which causes wall-bound particle clusters to detach from the interior filter surfaces. For wetted filters, the capillary adhesion force is orders of magnitude greater than the Saffman lift force, and consequently the filtration efficiency is not adversely affected. We developed models for filter pressure drop and filtration efficiency accounting for the influence of particle adhesion forces; these models showed good agreement with experimental results. Filter quality factor (QF) was determined for varying particle sizes and flowrates and can be used as a design guideline for use-case-specific filter optimization, which is enabled by the customizable additive manufacturing approach used to fabricate the filters. Due to its versatility and low-pressure-drop nature, this filtration approach could find use in heating, ventilation, and air conditioning (HVAC), large particle and dust filtration in industrial processes, cleanroom pre-filtration, and beyond.

description: We present four large sets of evolutionary tracks for stars with initial chemical compositions [Y=0.250, Z=0.008], [Y=0.273, Z=0.019], [Y=0.320, Z=0.040] and [Y=0.390, Z=0.070] and enhancement of alpha elements with respect to the solar pattern. The major improvement with respect to previous similar calculations is that we use consistent opacities - i.e. computed with the same chemical composition as adopted in the stellar models - over the whole relevant range of temperatures. For the same initial chemical compositions [Y,Z] and otherwise identical input physics we present also new evolutionary sequences with solar-scaled mixtures of abundances. Based on these stellar models we calculate the corresponding sets of isochrones both in the Johnson-Cousins UBVRIJHK and HST/WFPC2 photometric systems. Furthermore, we derive integrated magnitudes, colours and mass-to-light ratios for ideal single stellar populations with total mass equal to 1 Msun. Finally, the major changes in the tracks, isochrones, and integrated magnitudes and colours passing from solar-scaled to alpha-enhanced mixtures are briefly outlined.

description: Abstract: "In order to solve the production planning problem given in 'Part I', a successive disaggregation algorithm is developed based on extensive sensitivity analysis for guiding the decisions on how to repartition the aggregate probability space. The partitioning algorithm is guaranteed to converge to the exact solution in a finite number of iterations, and has a highly parallel decomposition and computer implementation. Example problems are presented to demonstrate the solution technique. Results are compared with the alternative solution methods, variants of Benders decomposition schemes tailored to the dynamic staircase LP structure."
Hardware-Efficient Bosonic Quantum Error-Correcting Codes Based on Symmetry Operators

description: We establish a symmetry-operator framework for designing quantum error correcting~(QEC) codes based on fundamental properties of the underlying system dynamics. Based on this framework, we propose three hardware-efficient bosonic QEC codes that are suitable for $χ^{(2)}$-interaction based quantum computation: the $χ^{(2)}$ parity-check code, the $χ^{(2)}$ embedded error-correcting code, and the $χ^{(2)}$ binomial code, all of which detect photon-loss or photon-gain errors by means of photon-number parity measurements and then correct them via $χ^{(2)}$ Hamiltonian evolutions and linear-optics transformations. Our symmetry-operator framework provides a systematic procedure for finding QEC codes that are not stabilizer codes. The $χ^{(2)}$ binomial code is of special interest because, with $m\le N$ identified from channel monitoring, it can correct $m$-photon loss errors, $m$-photon gain errors, and $(m-1)$th-order dephasing errors using logical qudits that are encoded in $O(N)$ photons. In comparison, other bosonic QEC codes require $O(N^2)$ photons to correct the same degree of bosonic errors. Such improved photon-efficiency underscores the additional error-correction power that can be provided by channel monitoring. We develop quantum Hamming bounds for photon-loss errors in the code subspaces associated with the $χ^{(2)}$ parity-check code and the $χ^{(2)}$ embedded error-correcting code, and we prove that these codes saturate their respective bounds. Our $χ^{(2)}$ QEC codes exhibit hardware efficiency in that they address the principal error mechanisms and exploit the available physical interactions of the underlying hardware, thus reducing the physical resources required for implementing their encoding, decoding, and error-correction operations, and their universal encoded-basis gate sets.

description: R is unparalleled in its ability to transform raw data into a wide array of beautiful graphics, all within the same environment. However, when it comes to complex, multi-paneled plots, users rely on 3rd party graphic design software to arrange and customize plots. Here we present BentoBox, a coordinate-based genomic data visualization package that will revolutionize multi-figure plotting in R. Employing grid Graphics and drawing from the paradigms of base plotting and ggplot2, BentoBox offers precise, programmatic control over the placement, aesthetics, and arrangements of plots through a user-defined page with explicit units of measurement. Its edge-to-edge, containerized visualizations preserve the mapping between user-specified containers and the represented data, ensuring accurate alignment of plots in the same genomic region. Operating entirely within the R environment, BentoBox is optimized to quickly and easily read, plot, and arrange multi-omic data for an endless number of use cases. Come join us in changing how we plot in R!

description: The polarity-dependent resistive-switching across metal-Pr0.7Ca0.3MnO3 interfaces is investigated. The data suggest that shallow defects in the interface dominate the switching. Their density and fluctuation, therefore, will ultimately limit the device size. While the defects generated/annihilated by the pulses and the associated carrier depletion seem to play the major role at lower defect density, the defect correlations and their associated hopping ranges appear to dominate at higher defect density. Therefore, the switching characteristics, especially the size-scalability, may be altered through interface treatments.

description: We carry out analyses of some parameters of the galactic spiral arms, in the currently available samples. We present a catalog of the observed pitch angle for each spiral arm in the Milky Way disk. For each long spiral arm in the Milky Way, we investigate for each individual arm its pitch angle, as measured through different methods (parallaxes, twin-tangent arm, kinematical, etc), and assess their answers. Second, we catalog recent advances in the cartography of the Galaxy (global mean arm pitch, arm number, arm shape, interarm distance at the Sun). We statistically compare the results over a long time frame, from 1980 to 2017. Histograms of about 90 individual results published in recent years (since mid-2015) are compared to 66 earlier results (from 1980 to 2005), showing the ratio of primary to secondary peaks to have increased by almost a factor of 3. Similarly, many earlier discrepancies (expressed in r.m.s.) have been reduced by almost a factor 3.

description: Reactome is a free, open-source, curated, and peer-reviewed knowledgebase of biomolecular pathways. As of the current release, its holdings comprise 13,827 human reactions organized into 2,536 pathways involving 11,084 proteins, 1,857 small molecules, and 432 drugs, with the support of 33,752 literature references. These molecular entity and event annotations are systematically represented as an ordered network of molecular reactions, forming a graph of biological knowledge. Reactome has migrated from a relational database to a Neo4j graph database for efficient storage, processing, and access with these highly interconnected data. To minimize the usage of Neo4j Cypher queries, we developed an interface, ReactomeGraph4R, for interacting between R and a local Reactome graph database. The ReactomeGraph4R package retrieves data with a network structure and contains functions that permit complex tasks, such as i) finding hierarchical data of an instance; ii) getting the entire Reaction context using preceding or following relationships; and iii) displaying network graphs. Output data are formatted as R objects to assist with downstream analyses. We developed a second R package, ReactomeContentService4R, to wrap the RESTful API of the Content Service built on top of the graph core. These packages are available through Bioconductor and fulfill the needs of Reactome pathway- and network-based tools for analyzing multiple omics datasets.

description: We describe a numerical method which allows us to go beyond the classical approximation for the real-time dynamics of many-body systems by approximating the many-body Wigner function by the most general Gaussian function with time-dependent mean and dispersion. On a simple example of a classically chaotic system with two degrees of freedom we demonstrate that this Gaussian state approximation is accurate for significantly smaller field strengths and longer times than the classical one. Applying this approximation to matrix quantum mechanics, we demonstrate that the quantum Lyapunov exponents are in general smaller than their classical counterparts, and even seem to vanish below some temperature. This behavior resembles the finite-temperature phase transition which was found for this system in Monte-Carlo simulations, and ensures that the system does not violate the Maldacena-Shenker-Stanford bound $λ_L < 2 πT$, while the classical dynamics inevitably breaks the bound.

I dati riguardanti gli allievi sono stati raccolti grazie a degli items ripresi dal questionario MDI (Understanding our lives – The Middle Years Development Instrument) realizzato da Schonert-Reichl et al. 2010 a Vancouver. I dati degli allievi sono stati esposti dopo essere trattati con Excel-Office. I risultati mostrano un aumento nel benessere legato al senso di appartenenza e al clima di classe, mentre vi è una diminuzione dell’ottimismo, dell’empatia e del comportamento pro-sociale. Per quanto riguarda il docente vi è un aumento del proprio benessere, legato principalmente alla motivazione e alla soddisfazione nell’insegnare. Le interpretazioni dei dati sono generalizzabili unicamente per il campione classe preso in considerazione nello studio. Relatori: Luca Sciaroni, Alberto Crescentini. Materia: Scienze naturali.

description: We consider a particular large-radius limit of the worldsheet $S$-matrix for strings propagating on $AdS_5 \times S^5$. This limiting theory interpolates smoothly between the so-called plane-wave and giant-magnon regimes of the theory. The sigma model in this region simplifies; it stands as a toy model of the full theory, and may be easier to solve directly. The $S$ matrix of the limiting theory is non-trivial, and receives contributions to all orders in the $α'$ expansion. We analyze a guess for the full worldsheet $S$ matrix that was formulated recently by Beisert, Hernandez and Lopez, and Beisert, Eden, and Staudacher, and take the corresponding limit. After doing a Borel resummation we find that the proposed $S$ matrix reproduces the expected results in the giant-magnon region. In addition, we rely on general considerations to draw some basic conclusions about the analytic structure of the $S$ matrix.

description: For the characterization of the 10 mA ion beam delivered by the new High Current Linac at GSI, sophisticated, mainly non-intersepting diagnostic devices were developed. Besides the general set-up of a versatile test bench, we discuss in particular bunch shape and emittance measurements. A direct time-of-flight technique with a diamond particle detector is used to observe the micro-bunch distribution with a resolution of $\sim 25 $ ps equals 0.3$^{o}$ in phase. For the determination of the energy spread a coincidence technique is applied, using secondary electrons emitted by the ion passing through an aluminum foil 80 cm upstream of the diamond detector. The transverse emittance is measured within one macro pulse with a pepper-pot system equipped with a high performance CCD camera.

description: Using a simple transfer matrix approach we have derived very long series expansions for the perimeter generating function of punctured staircase polygons (staircase polygons with a single internal staircase hole). We find that all the terms in the generating function can be reproduced from a linear Fuchsian differential equation of order 8. We perform an analysis of the properties of the differential equation.

description: Acute respiratory distress syndrome (ARDS) is pathologically characterized by diffuse alveolar damage (DAD) and is associated with high morbidity and mortality rates. While pulmonary injury initiates alveolar-capillary barrier damage in ARDS, remodeling of the extracellular matrix (ECM), which is pivotal for both tissue repair and organ recovery, may play a large role in persistent ARDS. This study investigated the compositional changes in the ECM in different DAD stages in ARDS. Paraffin-embedded lung sections collected during autopsy or from post-transplant lungs were obtained from patients with ARDS (n=28) admitted to the University Medical Center Groningen between 2010-2020. Sections were stained histochemically, and immunohistochemically for collagen III α1 chain (Col IIIa1), IV α3 chain (Col IVa3), VI α1 chain (Col VIa1), periostin (PSTN), lumican (LUM), and fibronectin (FN). The sections were divided into 118 regions based on DAD stages (54 early vs 64 advanced). The differences in the expression of selected proteins were compared between DAD stages or across ARDS duration (<7days, 7-14days, >14days). The fiber pattern of Col VIa1 was analyzed using CellProfiler. Higher tissue density, lower proportional areas of Col IIIa1, Col IVa3, and LUM, and more concentrated Col VIa1 fibers were observed in the advanced DAD stage than in the early DAD stage. Areas with higher proportions of total collagen and FN, and lower proportional areas of Col IIIa1, Col IVa3, and LUM were detected in lung regions from patients with ARDS >14days duration. These findings revealed proportional changes in ECM components, strongly suggesting that dynamic changes in ECM proteins play a role in pathophysiology in ARDS during progression.

Superconducting Superstructure for the TESLA Collider: New Results

description: A new cavity-chain layout has been proposed for the main linac of the TESLA linear collider. This superstructure-layout is based upon four 7-cell superconducting standing-wave cavities, coupled by short beam pipes. The main advantages of the superstructure are an increase in the active accelerating length in TESLA and a saving in rf components, especially power couplers, as compared to the present 9-cell cavities. The proposed scheme allows to handle the field-flatness tuning and the HOM damping at sub-unit level, in contrast to standard multi-cell cavities. The superstructure-layout is extensively studied at DESY since 1999. Computations have been performed for the rf properties of the cavity-chain, the bunch-to-bunch energy spread and multibunch dynamics. A copper model of the superstructure has been built in order to compare with the simulations and for testing the field-profile tuning and the HOM damping scheme. A "proof of principle" niobium prototype of the superstructure is now under construction and will be tested with beam at the TESLA Test Facility in 2001. In this paper we present latest results of these investigations.

description: There are four key aspects for water use in hydraulic fracturing, including source water acquisition, wastewater production, reuse and recycle, and subsequent transportation, storage, and disposal. This work optimizes water use life cycle for wellpads through a discrete-time two-stage stochastic mixed-integer linear programming model under uncertain availability of water. The objective is to minimize expected transportation, treatment, storage, and disposal cost while accounting for the revenue from gas production. Assuming freshwater sources, river withdrawal data, location of wellpads and treatment facilities as given, the goal is to determine an optimal fracturing schedule in coordination with water transportation, and its treatment and reuse. The proposed models consider a long time horizon and multiple scenarios from historical data. Two examples representative of the Marcellus Shale play are presented to illustrate the effectiveness of the formulation, and to identify optimization opportunities that can improve both the environmental impact and economical use of water.

description: Deep learning algorithms are widely used in many fields of astronomy, and have a wide range of applications in transiting exoplanet detection and classification. We have trained an neural network using two-dimensional object detection algorithm with Kepler and TESS light curves. Our network outputs excellent performance on Kepler and TESS data. The detected transits can amplify their periodicity and our network can be easily used to find single transiting events and cluster multiple transits.

description: We present Direct Numerical Simulations of the transport of heat and heavy elements across a double-diffusive interface or a double-diffusive staircase, in conditions that are close to those one may expect to find near the boundary between the heavy-element rich core and the hydrogen-helium envelope of giant planets such as Jupiter. We find that the non-dimensional ratio of the buoyancy flux associated with heavy element transport to the buoyancy flux associated with heat transport lies roughly between 0.5 and 1, which is much larger than previous estimates derived by analogy with geophysical double-diffusive convection. Using these results in combination with a core-erosion model proposed by Guillot et al. (2004), we find that the entire core of Jupiter would be eroded within less than 1Myr assuming that the core-envelope boundary is composed of a single interface. We also propose an alternative model that is more appropriate in the presence of a well-established double-diffusive staircase, and find that in this limit a large fraction of the core could be preserved. These findings are interesting in the context of Juno's recent results, but call for further modeling efforts to better understand the process of core erosion from first principles.
