Poloidal Magnetic Fields In Superconducting Neutron Stars

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We develop the formalism for computing the magnetic field within an axisymmetric neutron star with a strong Type II superconductor core surrounded by a normal conductor. The formalism takes full account of the constraints imposed by hydrostatic equilibrium with a barotropic equation of state. We specialize to purely poloidal magnetic fields and develop the "most dipolar case" for which we find that the surface field strength is $\simeq H_bε_b/3\simeq 3\times 10^{12}$ G, where $H_b$ is the magnetic field at the outer edge of the core and $ε_b R$ is the thickness of the normal shell. This value only depends on the equation of state of nuclear matter. We also find that the quadrupolar distortion of the star is $\sim 10^{-9}$.

Citizen Participation in the Energy System at the Macro Level
Creators: name: Dunphy, Niall P.

Publisher: name: Zenodo
Year: 2020

description: Concepts of energy justice, energy democracy and energy citizenship are introduced and their importance in understanding citizen participation around energy was outlined. The report notes that the concept of the energy citizen remains a contested idea, with some commentators emphasising a normative perspective focused on responsibilities and obligations of ‘good citizens’, while others place a greater prominence on rights, arguing for a more inclusive and participatory conceptualisation. Following an analysis of modes of participation, six roles are identified and described in which citizen-consumers are permitted to play and/or want to play within the energy system.

description: Making use of the energetics and equations of state of defective uranium dioxide that calculated with first-principles method, we demonstrate a possibility of constraining the formation energy of point defects by measuring the transition pressures of the corresponding pseudo-phase of defects. The mechanically stable range of fluorite structure of UO2, which dictates the maximum possible pressure of relevant pseudo-phase transitions, gives rise to defect formation energies that span a wide band and overlap with the existing experimental estimates. We reveal that the knowledge about pseudo-phase boundaries can not only provide important information of energetics that is helpful for reducing the scattering in current estimates, but also be valuable for guiding theoretical assessments, even to validate or disprove a theory. In order to take defect interactions into account and to extrapolate the physical quantities at finite stoichiometry deviations to that near the stoichiometry, we develop a general formalism to describe the thermodynamics of a defective system. We also show that it is possible to include interactions among defects in a simple expression of point defect model (PDM) by introducing an auxiliary constant mean-field. This generalization of the simple PDM leads to great versatility that allows one to study nonlinear effects of stoichiometry deviation on materials' behavior. It is a powerful tool to extract the defect energetics from finite defect concentrations to the dilute limit. Besides these, the full content of the theoretical formalism and some relevant and interesting issues, including reentrant pseudo-transition, multi-defect coexistence, charged defects, and possible consequence of instantaneous defective response in a quantum crystal, are explored and discussed.

Variable selection in linear mixed effects models
Creators: name: Fan, Yingying

Publisher: name: arXiv
Year: 2012
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: This paper is concerned with the selection and estimation of fixed and random effects in linear mixed effects models. We propose a class of nonconcave penalized profile likelihood methods for selecting and estimating important fixed effects. To overcome the difficulty of unknown covariance matrix of random effects, we propose to use a proxy matrix in the penalized profile likelihood. We establish conditions on the choice of the proxy matrix and show that the proposed procedure enjoys the model selection consistency where the number of fixed effects is allowed to grow exponentially with the sample size. We further propose a group variable selection strategy to simultaneously select and estimate important random effects, where the unknown covariance matrix of random effects is replaced with a proxy matrix. We prove that, with the proxy matrix appropriately chosen, the proposed procedure can identify all true random effects with asymptotic probability one, where the dimension of random effects vector is allowed to increase exponentially with the sample size. Monte Carlo simulation studies are conducted to examine the finite-sample performance of the proposed procedures. We further illustrate the proposed procedures via a real data example.

description: As storage systems become increasingly heterogeneous and complex, it adds burdens on DBAs, causing suboptimal performance even after a lot of human efforts have been made. In addition, existing monitoring-based storage management by access pattern detections has difficulties to handle workloads that are highly dynamic and concurrent. To achieve high performance by best utilizing heterogeneous storage devices, we have designed and implemented a heterogeneity-aware software framework for DBMS storage management called hStorage-DB, where semantic information that is critical for storage I/O is identified and passed to the storage manager. According to the collected semantic information, requests are classified into different types. Each type is assigned a proper QoS policy supported by the underlying storage system, so that every request will be served with a suitable storage device. With hStorage-DB, we can well utilize semantic information that cannot be detected through data access monitoring but is particularly important for a hybrid storage system. To show the effectiveness of hStorage-DB, we have implemented a system prototype that consists of an I/O request classification enabled DBMS, and a hybrid storage system that is organized into a two-level caching hierarchy. Our performance evaluation shows that hStorage-DB can automatically make proper decisions for data allocation in different storage devices and make substantial performance improvements in a cost-efficient way.

description: We analyze the Agatston score of coronary artery calcium (CAC) from the Multi-Ethnic Study of Atherosclerosis (MESA) using the semiparametric zero-inflated modeling approach, where the observed CAC scores from this cohort consist of high frequency of zeroes and continuously distributed positive values. Both partially constrained and unconstrained models are considered to investigate the underlying biological processes of CAC development from zero to positive, and from small amount to large amount. Different from existing studies, a model selection procedure based on likelihood cross-validation is adopted to identify the optimal model, which is justified by comparative Monte Carlo studies. A shrinkaged version of cubic regression spline is used for model estimation and variable selection simultaneously. When applying the proposed methods to the MESA data analysis, we show that the two biological mechanisms influencing the initiation of CAC and the magnitude of CAC when it is positive are better characterized by an unconstrained zero-inflated normal model. Our results are significantly different from those in published studies, and may provide further insights into the biological mechanisms underlying CAC development in humans. This highly flexible statistical framework can be applied to zero-inflated data analyses in other areas.

description: Rastall's theory is a modification of Einstein's theory of gravity where the covariant divergence of the stress-energy tensor is no more vanishing, but proportional to the gradient of the Ricci scalar. The motivation of this theory is to investigate a possible non-minimal coupling of the matter fields to geometry which, being proportional to the curvature scalar, may represent an effective description of quantum gravity effects. Non-conservation of the stress-energy tensor, via Bianchi identities, implies new field equations which have been recently used in a cosmological context, leading to some interesting results. In this paper we adopt Rastall's theory to reproduce some features of the effective Friedmann's equation emerging from loop quantum cosmology. We determine a class of bouncing cosmological solutions and comment about the possibility of employing these models as effective descriptions of the full quantum theory.

description: Adaptive homodyne estimation of a continuously evolving optical phase using time-symmetric quantum smoothing has been demonstrated experimentally to provide superior accuracy in the phase estimate compared to adaptive or nonadaptive estimation using filtering alone. Here, we illustrate how the mean-square error in the adaptive phase estimate may be further reduced below the standard quantum limit for the stochastic noise process considered by using a Rauch-Tung-Striebel smoother as the estimator, alongwith an optimal Kalman filter in the feedback loop. Further, the estimation using smoothing can be made robust to uncertainties in the underlying parameters of the noise process modulating the system phase to be estimated. This has been done using a robust fixed-interval smoother designed for uncertain systems satisfying a certain integral quadratic constraint.

INTEGRATED ALGAE BIO REFINERY: NUTRIENT AND CARBON RECYCLING FROM WASTE
Creators: name: SU, MIN
Publisher: name: Universit� degli Studi di Milano
Year: 2021

description: Driven by the sustained growth of resource consumption and waste generation, the circular economy has received much attention as a solution to surmount the consumption and production demand of goods. Microalgae are a key component of circular economy where they can be used as a source of biomass, products and energy. Under this circumstances, this Ph.D thesis aimed to provide the effectiveness of algae-waste based system. Particularly, this work mainly focused on integrating microalgae with various organic waste streams treatment by achieving nutrient recovery of the wastes as well as producing algal biomasses. Instead of applying the microalgae pure species, the innovation of this work (Chapter ?) explored and demonstrated the potential for isolating and cultivating microalgae-microbial consortia (AC) from different organic wastes as original growing substrates, providing the knowledge of the structure, diversity and population of Eukaryotic and Prokaryotic compositions of these microbial-microalgae consortia communities. The survived and well adapted ACs were analyzed by next generation sequencing technology. Then in Chapter ?, these ACs have been applied on nutrient rich waste stream (nanofiltrated pig slurry) in autotrophic condition to be evaluated their growth ability for producing biomass and nutrients recovery ability for treating wastes. Furthermore, biochemical compositions have been tested along with the fatty acids and amino acids profiles for further application potential. Microalgae can not only grow under autotrophic condition, but they can also grow under mixotrophic nutrition by combining both the autotrophic and heterotrophic mechanisms by assimilating available organic compounds as well as atmospheric CO2 as carbon source. A difference approach in Chapter ? using as substrate a similar waste stream studied in Chapter II added of C source to support microalgae growing in mixotrophic, i.e. glycerol, mode was conducted. Phaeodactylum tricornutum was selected since this strain can grow in mixotrophic condition in the presence of diverse organic compounds and it has been included among potential candidates for biodiesel production due to its high lipid content. Thus, this chapter represents an attempt to assess the ability of the algae P. tricornutum to grow mixotrophically and providing comparison with autotrophic condition.

description: We demonstrate a high-contrast electro-optic modulation of a photonic crystal nanocavity integrated with an electrically gated monolayer graphene. A high quality (Q) factor air-slot nanocavity design is employed for high overlap between the optical field and graphene sheet. Tuning of graphene's Fermi level up to 0.8 eV enables efficient control of its complex dielectric constant, which allows modulation of the cavity reflection in excess of 10 dB for a swing voltage of only 1.5 V. We also observe a controllable resonance wavelength shift close to 2 nm around a wavelength of 1570 nm and a Q factor modulation in excess of three. These observations allow cavity-enhanced measurements of the graphene complex dielectric constant under different chemical potentials, in agreement with a theoretical model of the graphene dielectric constant under gating. This graphene-based nanocavity modulation demonstrates the feasibility of high-contrast, low-power frequency-selective electro-optic nanocavity modulators in graphene-integrated silicon photonic chips.

description: We consider the factorisation of one-loop amplitudes at complex kinematic points. By determining the terms that are absent for real kinematics, we can construct a recursive ansatz for the purely rational pieces of one-loop amplitudes in massless theories. We illustrate this method by verifying the Bern et.al. n-point ansatze for the single-minus one-loop amplitudes in Yang-Mills theory and by constructing the scalar contribution to the one-loop five graviton MHV scattering amplitude.
NEW SYNTHETIC STRATEGIES FOR THE PREPARATION OF HETEROCYCLIC AND HETEROPOLYCYCLIC COMPOUNDS
Creators: name: DELL'ACQUA, MONICA
Publisher: name: Universit� degli Studi di Milano
Year: 2012

description: The aim of the project of this doctoral thesis is the development of new synthetic strategies for the preparation of heterocyclic and heteropolycyclic compounds of potential interest in biological and pharmacological fields. In particular, we studied new general, flexible and regioselective synthetic approaches to oxygen and nitrogen heterocycles. We showed the versatility of nucleophilic addition/annulation domino reactions of alkyne compounds bearing a proximate nucleophile in the synthesis of heterocyclic systems, such as dihydroisobenzofurans, isoquinolines and naphthyridines. These approaches have been successfully transformed in Pd-catalysed multicomponent processes involving a one-pot coupling/addition/cyclisation sequence starting from the simple building blocks, such as ortho-bromoarylaldehydes, terminal alkynes and methanol or ammonia. In some cases, the reactivity of less reactive alkyne substrates has been enhanced by the catalysis of alkynophilic transition metals, such as gold and silver. In particular, we reported a new silver-catalysed approach to 2-methylisoquinolines and 5-methyl-1,6-naphtyridines by tandem addition/cyclisation of ?-ketoalkynes with ammonia. The domino approach has been also extended to 2-acetyl-N-propargylpyrroles for the synthesis of pyrrolo[1,2-a]pyrazine. In this case TiCl4 revealed to be the best promoter. Microwave heating demonstrated to be able to improve the efficiency of both domino and multicomponent processes. Finally, the project developed at the Institut f�r Organische und Biomolekulare Chemie in the Georg-August-Universit�t G�ttingen (Germany), under the supervision of Prof. L. Ackermann, concerned with the direct arylations of indoles and pyrroles with differently substituted diaryliodonium salts in the absence of metal catalysts. The protocol proved broadly applicable, thereby enabling C-H bond functionalisations of free (NH)- as well as N-substituted indoles and pyrroles.
ANALYSIS OF TFEB NUCLEO-CYTOPLASMIC SHUTTLING DYNAMICS IN RESPONSE TO NUTRIENTS AVAILABILITY
Creators: name: BENEDETTI, VALERIO
Publisher: name: Universit� degli Studi di Milano
Year: 2020

description: The transcription factor EB (TFEB) is a key transcriptional regulator of lysosomal biogenesis and autophagy in response to variations in nutrient availability. TFEB subcellular localization and transcriptional activity are mainly controlled by its phosphorylation status. At the steady state, TFEB is normally phosphorylated and sequestered in the cytoplasm in an inactive form. Amino acids deprivation induces TFEB dephosphorylation and subsequent nuclear translocation, thus promoting the transcriptional activation of catabolic processes, including autophagy and lysosomal biogenesis. However, how nuclear TFEB is inactivated upon nutrient refeeding was until recently poorly understood. Our study on TFEB nucleo-cytoplasmic shuttling dynamics showed that TFEB continuously shuttles between the cytosol and the nucleus and highlighted the nuclear export as a new important checkpoint in the modulation of TFEB subcellular localization. TFEB nuclear export is mediated by the exportin CRM1, which recognizes a previously uncharacterized Nuclear Export Signal (NES) in the TFEB sequence. In addition, we found that this process requires a hierarchical multisite mTOR-dependent nuclear phosphorylation of TFEB on S142 and S138 residues, which allows its interaction with CRM1 and subsequent nuclear export in response to nutrients. Thus, our study reveals a complex scenario in which TFEB phosphorylation may occur in different subcellular compartments to finely tune its nucleo-to-cytoplasm shuttling. This model may unveil new pharmacological strategies aimed to control TFEB localization and activity by modulating its nuclear import and nuclear export in human diseases associated with autophagy or lysosomal defects, such as neurodegenerative and lysosomal storage disorders.

description: The view that silos are endemic in organisations in general and the European Civil Service in particular has become increasingly widespread. Yet, silos are rarely investigated theoretically or empirically. What is a silo? What are the individual and organisational factors associated with silos? We propose a functionalist approach to silo definition and identification, which links individual and organisational tasks to expected intra-organisational interactions: we operationalise silos as clusters of employees lacking communication with other parts of the organisation, and analyse civil servants and departments as bipartite networks of communication using stochastic blockmodelling. We explore the existence of silos in two European bureaucracies, which differ in mission, size and workforce composition: the European Commission and the General Secretariat of the Council. We do not find evidence of silo-isation in either bureaucracy, but rather task-based patterns of interaction. Our approach can be extended to include other theoretical perspectives, e.g., socialisation effects.

KL-optimality is a general criterion useful to select the best experimental conditions to discriminate between statistical models. A KL-optimum design is obtained from a minimax optimization problem, which is defined on a infinite-dimensional space. In particular, continuity of the KL-optimality criterion is proved under mild conditions; as a consequence, the first-order algorithm converges to the set of KL-optimum designs for a large class of models. It is also shown that KL-optimum designs are invariant to any scale-position transformation. Some examples are given and discussed, together with some practical implications for numerical computation purposes.

description: When investors have heterogeneous attitudes towards risk, it is reasonable to assume that each investor has a pricing kernel, and that these individual pricing kernels are aggregated to form a market pricing kernel. The various investors are then buyers or sellers depending on how their individual pricing kernels compare to that of the market. In Brownian-based models, we can represent such heterogeneous attitudes by letting the market price of risk be a random variable, the distribution of which corresponds to the variability of attitude across the market. If the flow of market information is determined by the movements of prices, then neither the Brownian driver nor the market price of risk are directly visible: the filtration is generated by an "information process" given by a combination of the two. We show that the market pricing kernel is then given by the harmonic mean of the individual pricing kernels associated with the various market participants. Remarkably, with an appropriate definition of Lévy information one draws the same conclusion in the case when asset prices can jump. As a consequence we are led to a rather general scheme for the management of investments in heterogeneous markets subject to jump risk.

description: In this article, we explore the determinants of reforms intending to integrate policies and coordinate administrative units by focusing on necessary conditions. Firstly, we elaborate theoretical expectations about potential necessary conditions for cross-sectoral reforms. Secondly, we conduct a condition-oriented fuzzy-set qualitative comparative analysis to examine our expectations, based on an original data set comparing policy integration and administrative coordination reforms, in environmental and unemployment policy, across 13 countries over 29 years. Our results indicate three necessary conditions for high reform intensity: external problem pressure is necessary for policy integration and administrative coordination in employment policy; either the strength or weakness of the reference party can take the role of necessary conditions depending on the policy field; low politicization of bureaucracy is necessary, especially for administrative coordination in environmental policy. These findings contribute to the development of a systematic theory of cross-sectoral policy and administrative change.

description: An efficient numerical method based on half-space Green function and spherical harmonics expansion is used to study the light scattering from coupled multiple nanospheres on a substrate. The ellipsometric spectra for various geometries of coupled Au nanospheres are calculated and analyzed to realize the effects of plasmonic coupling of closely-spaced nanospheres. With only a few parameters to describe the distribution of various coupled nanosphere clusters embedded in a random distribution of nanospheres, the calculated ellipsometric spectra can fit the experimental data very well. This illustrates that our realistic model calculations can be used for determination of the distribution of nanospheres on a substrate or embedded in multilayer structures such as biological samples.
The asymmetric long-term electoral consequences of unpopular reforms: why retrenchment really is a losing game for left parties

description: Debates about the electoral malaise of the Left, punishment for cutbacks, and left parties as credible protectors of the welfare state have neglected the long-term consequences of retrenchment. To find out how reforms affect parties’ popularity beyond individual government periods, we track the electoral performance of government parties over five elections and assess the interplay of unpopular reforms, partisanship, and the economic legacy. Based on well-known asymmetries in the conditionality of welfare support among parties’ core groups, we hypothesize that right parties reap the economic fruits of their reform labour, whereas left parties struggle to claim credit even if the promised positive economic legacy materializes. Our analyses of the consequences of retrenchment for 196 cabinets in 18 countries confirm that losses of left parties after reforms – in contrast to losses of right parties – are permanent and independent of the economic legacy; creating a tragedy of social-democratic responsibility.

description: Despite the large literature on gender differences in politics, there have been relatively few empirical studies testing the effects of gender in public administration. This paper examines how male and female public managers show attitudinal differences toward innovation in the public sector. We hypothesize that male and female managers differ in three aspects. Firstly, female managers are more result-oriented than rule-following, and more oriented toward societal interests. Secondly, female public managers are more open to new ideas and creativity, and more willing to challenge the status quo. Yet, thirdly, female leaders are less eager to take risks when would-be innovations may put their organizations in peril. Thus, we argue that female managers are more prudent and entrepreneurial than their male counterparts. We test these hypotheses using a data set of 5,909 senior public managers from 20 European countries. The results of multilevel model analysis find statistically significant gender differences in attitudes toward innovation. Despite the small size of gender impacts, our findings challenge prevailing stereotypes on women’s entrepreneurial attitudes.
An X-ray Detected Group of Quiescent Early-type Galaxies at z=1.6 in the Chandra Deep Field South

description: (Abridged) We report the discovery of an X-ray group of galaxies located at a high redshift of z=1.61 in the Chandra Deep Field South. The group is first identified as an extended X-ray source. We use a wealth of deep multi-wavelength data to identify the optical counterpart -- our red sequence finder detects a significant over-density of galaxies at z~1.6 and the brightest group galaxy is spectroscopically confirmed at z=1.61. We measure an X-ray luminosity of L_{0.1-2.4 keV}= 1.8\pm0.6 \times 10^{43} erg/s, which then translates into a group mass of 3.2\pm0.8 \times 10^{13} M_sun. This is the lowest mass group ever confirmed at z>1.5. The deep optical-nearIR images from CANDELS reveal that the group exhibits a surprisingly prominent red sequence. A detailed analysis of the spectral energy distributions of the group member candidates confirms that most of them are indeed passive galaxies. Furthermore, their structural parameters measured from the near-IR CANDELS images show that they are morphologically early-type. The newly identified group at z=1.61 is dominated by quiescent early-type galaxies and the group appears similar to those in the local Universe. One possible difference is the high fraction of AGN (38^{+23}_{-20}%), which might indicate a role for AGN in quenching. But, a statistical sample of high-z groups is needed to draw a general picture of groups at this redshift. Such a sample will hopefully be available in near future surveys.

Optical-Near Infrared Color Gradients And Merging History Of Elliptical Galaxies

description: It has been suggested that merging plays an important role in the formation and the evolution of elliptical galaxies(EGs). In order to understand the past merging history of EGs, we studied the optical-NIR color gradients of 204 EGs. The use of the optical and the NIR data provides large wavelength baselines, and breaks the age-metallicity(Z) degeneracy, allowing us to derive age and Z gradients. The use of the deep SDSS Stripe 82 images make it possible for us to examine how the color/age/Z gradients are related to merging features. We find that the optical-NIR color and the age/Z gradients of EGs with tidal features are consistent with those of relaxed EGs suggesting that the two populations underwent a similar merging history on average and that mixing of stars was more or less completed before the tidal features disappear. EGs with dust features have steeper color gradients than the other two types, even after masking out dust features during the analysis, which can be due to a process involving wet merging. More importantly, we find that the scatter in the color/age/Z gradients of the relaxed and merging feature types, decreases as their luminosities increase at M > 10^{11.4} M_{\odot} but stays to be large at lower luminosities. Mean Z gradients appear nearly constant over the explored mass range, but a possible flattening is observed at the massive end. According to our toy model that predicts how the distribution of Z gradients changes as a result of major dry merging, the mean Z gradient should flatten by 40% and its scatter become smaller by 80% per a mass doubling scale if EGs evolve only through major dry merger. Our result, although limited by a number statistics at the massive end, is consistent with the picture that major dry merging is an important mechanism for the evolution for EGs at M > 10^{11.4} M_{\odot}, but less important at the lower mass range.

description: This article reviews many manifestations and applications of dual representations of pairs of groups, primarily in atomic and nuclear physics. Examples are given to show how such paired representations are powerful aids in understanding the dynamics associated with shell-model coupling schemes and in identifying the physical situations for which a given scheme is most appropriate. In particular, they suggest model Hamiltonians that are diagonal in the various coupling schemes. The dual pairing of group representations has been applied profitably in mathematics to the study of invariant theory. We show that parallel applications to the theory of symmetry and dynamical groups in physics are equally valuable. In particular, the pairing of the representations of a discrete group with those of a continuous Lie group or those of a compact Lie with those of a non-compact Lie group makes it possible to infer many properties of difficult groups from those of simpler groups. This review starts with the representations of the symmetric and unitary groups, which are used extensively in the many-particle quantum mechanics of bosonic and fermionic systems. It gives a summary of the many solutions and computational techniques for solving problems that arise in applications of symmetry methods in physics and which result from the famous Schur-Weyl duality theorem for the pairing of these representations. It continues to examine many chains of symmetry groups and dual chains of dynamical groups associated with the several coupling schemes in atomic and nuclear shell models and the valuable insights and applications that result from this examination.
