description: Many materials containing colloids or polymers are polydisperse: They comprise particles with properties (such as particle diameter, charge, or polymer chain length) that depend continuously on one or several parameters. This review focusses on the theoretical prediction of phase equilibria in polydisperse systems; the presence of an effectively infinite number of distinguishable particle species makes this a highly nontrivial task. I first describe qualitatively some of the novel features of polydisperse phase behaviour, and outline a theoretical framework within which they can be explored. Current techniques for predicting polydisperse phase equilibria are then reviewed. I also discuss applications to some simple model systems including homopolymers and random copolymers, spherical colloids and colloid-polymer mixtures, and liquid crystals formed from rod- and plate-like colloidal particles; the results surveyed give an idea of the rich phenomenology of polydisperse phase behaviour. Extensions to the study of polydispersity effects on interfacial behaviour and phase separation kinetics are outlined briefly.

description: The conceptualisation of disability is contested globally and issues in gender studies further complicate the movement towards the development of an inclusive and equal society. However, most disability and gender research studies are based on the data collected in the Global North, and little is known about disabled women in the Global South. The data presented here is from a bigger study focusing on the lived experiences of women with disabilities. This paper sets to explore how disabled women in Malaysia experience their lives in terms of marriage and motherhood prospects. The data of this qualitative study was collected from a set of in-depth interviews involving 32 women in Malaysia with physical (mobility) impairment. Over a period of 6 months, 16 Malays, 8 Chinese and 8 Indian women were interviewed twice. The analysis proposes both retrospective and introspective accounts on marriage and motherhood. The data gathered from the in-depth interviews was transcribed and analysed thematically with the help of NVivo software. The findings indicated that most participants have experienced significant barriers concerning individual constraints, familial control, and societal barriers. These were discussed with the intrinsic aspects and contextual factors of living in a patriarchal and traditional society that significantly undermined the wellbeing of disabled women in this study. Nevertheless, many of those interviewed refused to give up their hope of having a family life despite the constant struggles they encountered in their pursuit of happiness. However, their aspirations to experience family life were restricted and this caused them to experience significant psycho-emotional problems. They were constantly reminded that they were ‘disabled’ and not worthy of experiencing life like other women. The paper will discuss these challenges and negative societal attitudes towards the issue.

description: The longstanding dispute over the accuracy of stated preference methods in eliciting the true valuations of individuals has stimulated interest in analyzing preference inconsistencies between revealed and stated preference mechanisms. This paper uses preference orderings to provide a more robust comparison between revealed and stated preferences and assess the validity of the latter. This is done by comparing an incentive compatible auction experiment (recoded as implied ranks) with a ranking procedure. Partial ranking models are constructed to examine consumer preferences under the two valuation mechanisms for the most preferred and the least preferred alternatives in order to provide a more detailed analysis. The stability and symmetry of parameters was tested and systematic differences between the models were analyzed in order to measure the extent of preference inconsistencies between the auction exercise and ranking procedure. Furthermore, the predictive power of the models was calculated to evaluate the relative reliability of each mechanism. The results provide robust evidence that individuals often employ different behavioral rules under the two elicitation mechanisms, especially when expressing mild feelings about certain alternatives. Compared to the more accurate auctions mechanism, the ranking exercise seems to perform fairly well only when eliciting preferences over the best ranked alternative.

description: Studying the gauge-invariant renormalizability of four-dimensional Yang-Mills theory using the background field method and the BV-formalism, we derive a classical master-equation homogeneous with respect to the antibracket by introducing antifield partners to the background fields and parameters. The constructed model can be renormalized by the standard method of introducing counterterms. This model does not have (exact) multiplicative renormalizability but it does have this property in the physical sector (quasimultiplicative renormalizability).

Determination of the b Quark Mass at the Z Mass Scale

Year: 2001
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: In hadronic decays of Z bosons recorded with the OPAL detector at LEP, events containing b quarks were selected using the long lifetime of b flavoured hadrons. Comparing the 3-jet rate in b events with that in d,u,s and c quark events, a significant difference was observed. Using Order(alpha_s squared) calculations for massive quarks, this difference was used to determine the b quark mass in the MSbar renormalisation scheme at the scale of the Z boson mass. By combining the results from seven different jet finders the running b quark mass was determined to be mb(MZ) = (2.67 +/- 0.03(stat) +0.29/-0.37(syst) +/- 0.19(theo.)) GeV. Evolving this value to the b quark mass scale itself yields mb(mb) = (3.95 +0.52/-0.62) GeV, consistent with results obtained at the b quark production threshold. This determination confirms the QCD expectation of a scale dependent quark mass. A constant mass is ruled out by 3.9 standard deviations.

description: In this paper, we analyze how environmental disamenity affects residential location choices using a horizontal sorting model. The environmental disamenity is measured by the distances between houses and the nearest landfill and gravel pit. The study area in this paper is the Franklin County of Ohio State and each of the housing units chosen by the households in the sample represents a housing type. The first stage estimation results show that rich white householder are more likely to select houses with longer distance from the gravel pits and landfills than rich black householder. After controlling for the price endogeneity, the second stage estimation supports the hypothesis that longer distance to the landfill increases the fixed utility of the house. Also, the direction for the effect of distance to the nearest gravel pit is as expected, which indicates that households prefer to select houses with longer distance to the gravel pit operation.

Topological Gravity versus Supergravity on Manifolds with Special Holonomy

description: We construct a topological theory for euclidean gravity in four dimensions, by enforcing self-duality conditions on the spin connection. The corresponding topological symmetry is associated to the SU(2) X diffeomorphism X U(1) invariance. The action of this theory is that of d=4, N=2 supergravity, up to a twist. The topological field theory is SU(2) invariant, but the full SO(4) invariance is recovered after untwist. This suggest that the topological gravity is relevant for manifolds with special holonomy. The situation is comparable to that of the topological Yang-Mills theory in eight dimensions, for which the SO(8) invariance is broken down to Spin(7), but is recovered after untwisting the topological theory.

description: The antiferromagnetic coupling and entanglement between skyrmion lattices are treated in magnetic bilayer systems. We first formulate the problem of large bilayer skyrmions using $\mathbb{CP}^{1}\otimes \mathbb{CP}^{1}$ theory. We have considered bilayer skyrmions under the presence of Dzyaloshinskii-Moriya (DMI) and Zeeman interactions confined in a two-dimensional chiral magnet such as Fe$_{0.5}$Co$_{0.5}$Si. We parametrize bilayer skyrmions using $SU(4)$ representation, and represent each skyrmion and antiskyrmion using Schmidt decomposition. The reduced density matrices for skyrmion and antiskyrmion has been calculated. The conditions for maximal, partial entanglement and separable bilayer skyrmions are presented. Our results can be used for generating entanglement in systems with large number of spins.

description: —In this paper, the performance of the proposed off-grid wind-solar PV hybrid system powering the cathodic protection unit is simulated and analyzed using MATLAB/SIMULINK. Furthermore, the performance simulation for the battery energy storage system with PV-wind hybrid energy system under variable solar irradiance and wind speed respectively is also conducted. The hybrid system consists of a wind turbine which uses a permanent magnet synchronous generator driven directly from the turbine, a PV array and a battery bank. The simulated results reflect that the designed hybrid system of such capacity can adequately supply a cathodic protection unit with no power shortage at different weather conditions.

description: We present ab-initio calculations for the in plane conductivity of Co/Cu multilayer slabs. The electronic structure of the multilayer slabs is calculated by means of density functional theory within a screened KKR scheme. Transport properties are described using the Boltzmann equation in relaxation time approximation. We study the change of the conductivity during growth of the multilayer, and we can reproduce the anomalous, non Ohmic, behavior observed experimentally in several multilayer systems. Our results show that this behavior can be explained in terms of the electronic structure of the slab only. No extra assumption for the scattering at the interfaces is necessary. The connection of electronic structure and conductivity during layer-by-layer growth is elucidated by analyzing the layer-projected conductivities.

description: This paper is concerned with the investigation of the massless regime of an integrable spin chain based on the quantum group deformation of the $OSp(3|2)$ superalgebra. The finite-size properties of the eigenspectra are computed by solving the respective Bethe ansatz equations for large system sizes allowing us to uncover the low-lying critical exponents. We present evidences that critical exponents appear to be built in terms of composites of anomalous dimensions of two Coulomb gases with distinct radii and the exponents associated to $Z(2)$ degrees of freedom. This view is supported by the fact that the $S=1$ XXZ integrable chain spectrum is present in some of the sectors of our superspin chain at a particular value of the deformation parameter. We find that the fine structure of finite-size effects is very rich for a typical anisotropic spin chain. In fact, we argue on the existence of a family of states with the same conformal dimension whose lattice degeneracies are apparently lifted by logarithmic corrections. On the other hand we also report on states of the spectrum whose finite-size corrections seem to be governed by a power law behaviour. We finally observe that under toroidal boundary conditions the ground state dependence on the twist angle has two distinct analytical structures.

description: In this work, the packed thickness of pyrite’s effect on its conversion behavior and kinetics was investigated under air in high temperatures. The results showed that pyrite was oxidized to hematite directly with no more than 2 mm packed thickness, or indirect oxidation occurred (pyrite → pyrrhotite → hematite) when greater than 2 mm. Subsequently, the evolutions of pyrite were studied comprehensively by X-ray diffraction (XRD), Raman, Scanning electron microscope (SEM), and Transmission electron microscopy (TEM). The kinetics by the Avrami – Erofeev method displayed that the activation energy of the process of pyrite → hematite (27 KJ·mol−1) < pyrite → pyrrhotite (34 KJ·mol−1) < pyrrhotite → hematite (42 KJ·mol−1). The thinner-packed pyrite requires less energy to oxidize and more readily undergoes direct oxidation. The thermodynamics theoretically explained the reasons for indirect/direct oxidation of thicker-packed/thinner-packed pyrite that ΔGpyrrhotite < ΔGhematite in the thicker packed, or ΔGpyrrhotite > ΔGhematite in the thinner packed. This paper provided some fundamental and significant knowledge of pyrite oxidation to reduce SO2 emissions and industrial production safety.

WAVEFRONT SENSING

description: The pyramid wavefront sensor is an asset for an AO system thanks to its sensitivity. However, because its a nonlinear sensor it comes with operational challenges. A convolutional method and a gain sensing camera allow to track the optical gains, which encode the sensitivity variations due to the nonlinearities. Tracking and compensating the optical gains is necessary to perform extreme adaptive optics and to operate the pyramid off-zero to compensate for the NCPA.This study focuses on the reliability of this method. A numerical twin of the bench PAPYRUS, developed for this study, shows a improvement of the performance by a factor 2.7 on the Strehl Ratio when compensating for the optical gains. The convolutional method is implemented for the PAPYRUS bench, allowing the first on-sky tracking of optical gains. The next main steps are to compensate for the optical gains in real-time, then to offset the pyramid in order to optimise fiber-injection, to compensate for NCPA and to provide AO generated dark hole for high-contrast imaging.

description: We examine the five-region holographic entropy cone inequalities for the special case of the AdS$_3$-Vaidya metric for a variety of boundary configurations. This is done by numerically solving the geodesic equation in the bulk for various boundary configurations. In all the cases we examine, we find that all the inequalities are satisfied when the bulk satisfies the null energy condition, while the inequalities are all violated when the bulk spacetime violates the null energy condition. A proof of the five-region holographic entropy cone inequalities for the dynamical bulk case remains an open problem--our results provide evidence that these inequalities hold for dynamical bulk spacetimes.

This gives a TQFT such that its correlation functions in a slice are the same as those of the original quantum field theory.

description: We consider a possibility of the magnetostatic type spin waves driven by a long-range magnetic dipole interactions, to account for the peaks in the ESR spectra observed in our previous work. The Walker equation for magnetostatic modes is solved for a cylinder of atomic hydrogen, first in a uniform magnetic field and second in a linearly decreasing magnetic field. The frequency behavior of the solved modes with length of the cylinder and density of the gas is compared to experimental data. We conclude that magnetostatic modes are unlikely to account for the observed modulations of ESR spectra.

description: Non-LTE abundances of magnesium, aluminum and sulfur are derived for a sample of 23 low-v \sin i stars belonging to six northern OB associations of the Galactic disk within 1 kpc of the Sun. The abundances are obtained from the fitting of synthetic line profiles to high resolution spectra. A comparison of our results with HII region abundances indicates good agreement for sulfur while the cepheid abundances are higher. The derived abundances of Mg show good overlap with the cepheid results. The aluminum abundances for OB stars are significantly below the cepheid values. But, the OB star results show a dependence with effective temperature and need further investigation. The high Al abundances in the cepheids could be the result of mixing. A discussion of the oxygen abundance in objects near the solar circle suggests that the current mean galactic oxygen abundance in this region is 8.6-8.7 and in agreement with the recently revised oxygen abundance in the solar photosphere. Meaningful comparisons of the absolute S, Al and Mg abundances in OB stars with the Sun must await a reinvestigation of these elements, as well as the meteoritic reference element Si, with 3D hydrodynamical model atmospheres for the Sun. No abundance gradients are found within the limited range in galactocentric distances in the present study. Such variations would be expected only if there were large metallicity gradients in the disk.

description: There is growing evidence that brown dwarfs may be comparable to main-sequence stars in terms of their abundance. In this paper, we explore the prospects for the existence of life on Earth-like planets around brown dwarfs. We consider the following factors: (i) the length of time that planets can exist in the temporally shifting habitable zone, (ii) the minimum photon fluxes necessary for oxygenic photosynthesis, and (iii) the lower limits on the fluxes of ultraviolet radiation to drive prebiotic reactions ostensibly necessary for the origin of life. By taking these effects into consideration, we find that it is unlikely for brown dwarfs with masses $\lesssim 30 M_J$ to host habitable planets over geologically significant timescales. We also briefly discuss some of the major biosignatures that might arise on these planets, assess the likelihood of their detection, and highlight some avenues for further study.

description: To conduct a meta-analysis to determine the association between two single nucleotide polymorphisms (SNPs) miRNA146a rs2910164 (G > C) and miRNA-499 rs3746444 (T > C) and asthma risk. PubMed and Embase (updated May 17, 2019). (microRNA OR microRNAs) AND (polymorphism OR polymorphisms) AND (Asthmas OR Bronchial Asthma OR Asthma, Bronchial). Six eligible case-control studies (2441 asthma cases and 3044 controls) met our inclusion criteria. A trend of increased asthma risk was indicated by the heterozygote model (miR-499: TC versus TT, OR = 1.38, 95% CI = 1.06–1.79, P < 0.01) and the dominant model (miR-499: TC + CC versus TT, OR = 1.60, 95% CI = 1.07–2.39, P < 0.01) of miRNA-499 rs3746444. Polymorphisms rs2910164 in miRNA-146a of the allele model (miR-146a: C versus G, OR = 0.84, 95% CI = 0.74–0.96, P = 0.238), homozygote model (miR-146a: CC versus GG, OR = 0.68, 95% CI = 0.51–0.91, P = 0.213), recessive model (miR-146a: CC versus GC + GG, OR = 0.75, 95% CI = 0.60–0.94, P = 0.149) indicated a decreased risk of asthma. The miR-499 rs3746444 (T > C) polymorphism is associated with asthma susceptibility and miRNA-146a rs2910164 (G > C) polymorphism has a protective role against susceptibility to asthma.
Catalytic CO Oxidation on Nanoscale Pt Facets: Effect of Inter-Facet CO Diffusion on Bifurcation and Fluctuation Behavior

description: We present lattice-gas modeling of the steady-state behavior in CO oxidation on the facets of nanoscale metal clusters, with coupling via inter-facet CO diffusion. The model incorporates the key aspects of reaction process, such as rapid CO mobility within each facet, and strong nearest-neighbor repulsion between adsorbed O. The former justifies our use a "hybrid" simulation approach treating the CO coverage as a mean-field parameter. For an isolated facet, there is one bistable region where the system can exist in either a reactive state (with high oxygen coverage) or a (nearly CO-poisoned) inactive state. Diffusion between two facets is shown to induce complex multistability in the steady states of the system. The bifurcation diagram exhibits two regions with bistabilities due to the difference between adsorption properties of the facets. We explore the role of enhanced fluctuations in the proximity of a cusp bifurcation point associated with one facet in producing transitions between stable states on that facet, as well as their influence on fluctuations on the other facet. The results are expected to shed more light on the reaction kinetics for supported catalysts.

description: Backward proton and $π^-$ production has been studied in $ν_μCC$ interactions with carbon nuclei. Detailed analyses of the momentum distributions, of the production rates, and of the general features of events with a backward going particle, have been carried out in order to understand the mechanism producing these particles. The backward proton data have been compared with the predictions of the reinteraction and the short range correlation models.

description: Binary millisecond pulsars (MSPs) provide several opportunities for research of fundamental physics. However, finding them can be challenging. Several subdwarf B (sdB) binary systems with possible neutron star companions have been identified, allowing us to perform a targeted search for MSPs within these systems. Six sdBs with companions in the neutron star mass range, as determined from their optical light curves, were observed with the Green Bank and Westerbork radio telescopes. The data were searched for periodic signals as well as single pulses. No radio pulsations from sdB systems were detected, down to an average sensitivity limit of 0.11 mJy. We did, however, discover a pulsar in the field of sdB HE0532-4503. Follow-up observations with the Giant Metrewave Radio Telescope showed that this pulsar, J0533-4524, is not spatially coincident with the sdB system. The pulsar has a relatively low magnetic field but still emits giant pulses. We place an upper limit of three to the number of radio pulsars in the six sdB systems. The non-detections may be explained by a combination of the MSP beaming fraction, luminosity, and a recycling fraction <0.5. Alternatively, the assumption of co-rotation between the MSP and sdB may break down, which implies the systems are more edge-on than previously thought. This would shift the predicted companion masses into the white dwarf range. It would also explain the relative lack of edge-on sdB systems with massive companions.

On limits of superstring in AdS_5 x S^5

description: The superstring action in AdS_5 x S^5 depends on two parameters: the inverse string tension a' and the radius R. The standard AdS/CFT correspondence requires that the string coordinates are rescaled so that the action depends only on one combination of the two: (λ)^{1/2} = R^2/a'. Then λ\to 0 limit is equivalent to R \to 0 for fixed $a'$ or to the zero-tension limit in AdS_5 x S^5: a' \to \infty for fixed R. After reviewing previous work hep-th/0009171 on the light cone superstring we explicitly obtain the λ= 0 form of its action. Its zero-mode part is the same as the superparticle action in AdS_5 x S^5, and thus the λ=0 string spectrum must include, as expected, the ``protected'' type IIB supergravity states. Following recent suggestions, it is conjectured that the spectrum of this tensionless string should as well contain higher spin massless states in AdS_5. We also discuss the case of another parametrization of the string action which has straightforward R\to\infty flat space limit but where R \to 0 and a' \to \infty limits are not equivalent. There R \to 0 corresponds to shrinking S^5 to zero the size and ``freezing'' the fluctuations of the radial coordinate of AdS_5. This case is the basis of the ``non-standard'' AdS/CFT correspondence suggested in hep-th/0010106. Parts of this work were presented in the talk at ``Supergravity at 25'' conference, Stony Brook, December 1-2, 2001.

description: Abstract: Psychological adjustment significantly impacts the well-being of young individuals diagnosed with cancer. However, limited research examines the roles of self-esteem and social support, particularly with gender and age as potential moderators and mediators in low-resource settings like Uganda. This study investigated these relationships to inform gender-sensitive psychosocial interventions. Using a correlational research design, 98 participants aged 18–30 were recruited from cancer treatment centers in Uganda through multistage sampling. Data were collected using the Psychological Adjustment to Illness Scale, the Multidimensional Scale of Perceived Social Support, and Rosenberg’s Self-Esteem Scale, all demonstrating strong reliability (Cronbach’s α > 0.80). Analysis involved path modeling and conditional process analysis with SPSS and JASP software.

The result showed that self-esteem (β = 0.814, p < .001) and social support (β = 1.120, p < .001) significantly predicted better psychological adjustment. Gender moderated these relationships, with males benefiting more from self-esteem and social support than females. Age did not mediate the effects of social support or self-esteem on psychological adjustment. These results emphasize the importance of self-esteem and social support in enhancing psychological adjustment while highlighting gender disparities in their impact.

The findings underscore the need for gender-sensitive psychosocial support programs. Interventions should bolster self-esteem and foster social support for males while addressing systemic barriers affecting females. Policymakers should allocate resources to ensure equitable access to mental health support for young cancer patients.

description: A science centre was built in Debrecen with the purpose to extend natural scientific knowledge and increase commitment to science and innovation in an experience-focused way. In addition to science centres’ original role of education and scientific communication, their function has been extended for today with showcasing innovation and innovation findings, thereby “grabbing their slice” of the regional innovation process. However, in order to succeed, it is indispensable to maintain these institutions in the long run and to constantly renew their innovation content. By integrating the process established with using the “Triple Helix” approach, it is possible to assure one of the most important principles of the institution in the long run, which is its constant renewal that provides a wide range of the society with experiencebased “tangible” knowledge. By following the concept we use, it became obvious that a science centre – as an organisation which creates knowledge – calls for the direct collaboration of the government, science and business actors in order to successfully operate in the long run, to attain its goals and, consequently, to develop the innovation potential of the region. However, the accumulated knowledge as a result of strategic partnerships can only contribute to establishing regional knowledge if the user – the organisation of the Science centre in Debrecen – is able to convey it successfully to the members of the fourth and fifth helix.
