description: The Southern Ocean circulation plays a central role in the dynamics of past and future global climate change. However, due to a scarcity of observations and the difficulty of accurately modelling the Southern Ocean, we lack a comprehensive understanding of how the circulation responds to change. The energetic eddy field directly impacts the response of the circulation, but the small scale of the eddies has generally been below the resolution of numerical ocean models. This thesis makes use of two high resolution idealised ocean models to investigate the role of eddies in modifying the response of the Southern Ocean circulation to changing wind stress and surface buoyancy forcing. The simulations demonstrate that the eddy field is significant in the dynamical response, but that the impact on different aspects of the circulation is complex and subtle. The Antarctic Circumpolar Current (ACC) transport increases only weakly in response to enhanced Southern Ocean wind stress, due to the enhanced eddy field, which efficiently eliminates momentum input. In contrast, the eddy field only partially compensates wind- driven increases in the upper overturning circulation, resulting in a moderate overturning increase in response to enhanced westerly winds. Southern Ocean heat uptake is also shown to be dependent on changes in the eddy field. Mid-depth warming occurs primarily due to a decrease in the upward eddy heat flux, associated with reduced isopycnal temperature gradients in a warmer climate. However, increased wind stress may reduce the mid-depth heat uptake; a transient cooling trend arises from the wind-driven enhancement of the vertical eddy heat flux. The uncoupled idealised models also permit an in-depth analysis of the response of the Southern Ocean overturning to changes in surface buoyancy forcing. A suite of buoyancy forcing perturbations show that mid-latitude heat and freshwater fluxes may be as significant as wind stress in altering the strength of the upper overturning circulation. Analysis of the transient model response to a range of surface buoyancy forcing perturbations also indicates that recent observations are consistent with a slowdown of the lower overturning cell. In summary, this thesis has refined our understanding of how the large scale Southern Ocean circulation responds to atmospheric change and the role of the eddy field in modifying that response. This work provides a basis to interpret the more complicated response of coupled and coarse resolution models.

description: We use the Riess et al.(2004) supernova Ia apparent magnitude versus redshift data and the Allen et al.(2004) galaxy cluster gas mass fraction versus redshift data to constrain dark energy models. These data provide complementary constraints that when combined together ignificantly restrict model parameters and favor lowly-evolving dark energy density models, close to the Einstein cosmological constant limit of dark energy.

description: Single-photon detection is an invaluable tool for many applications ranging from basic research to consumer electronics. In this respect, the Single Photon Avalanche Diode (SPAD) plays a key role in enabling a broad diffusion of these techniques thanks to its remarkable performance, room-temperature operation, and scalability. In this paper we present a silicon technology that allows the fabrication of SPAD-arrays with an unprecedented combination of low timing jitter (95 ps FWHM) and high detection efficiency at red and near infrared wavelengths (peak of 70% at 650 nm, 45% at 800 nm). We discuss the device structure, the fabrication process, and we present a thorough experimental characterization of the fabricated detectors. We think that these long-awaited results can pave the way to new exciting developments in many fields, ranging from quantum optics to single molecule spectroscopy

description: Information about the medicinal uses of forty-two plant species was collected from traditional healers and knowledgeable villagers from a variety of different ethnic groups in Nepal. Illnesses for which these plants are used are those perceived in western style medicine to be caused by bacterial, fungal or viral pathogens. Methanol extracts of the species were screened for activity against a variety of bacteria, fungi and viruses, under various light conditions to test for photosensitizers. Thirty-seven extracts showed activity against bacteria and thirty-five showed activity against fungi. Only eight were active against Gram-negative bacteria. The exposure to UV-A light had a considerable effect on the activities of some extracts, with eight extracts being active only when exposed to light. The antibacterial and antifungal effects of fifteen extracts were enhanced upon exposure to light. Fifteen extracts showed 100% inactivation of at least one virus, and fifteen showed partial activity. Eight extracts were active only when exposed to light, and the antiviral effect of eight extracts was enhanced upon exposure to light. A species showing antibacterial activity, Centipeda minima (Asteraceae), and one showing antiviral activity, Carissa carandas (Apocynaceae) were the focus of bioactivity guided fractionation. Centipeda minima was found to contain three sesquiterpene lactones, identified as 6-O-methylacrylylplenolin, 6-O-isobutyroylplenolin, and 6-O-angeloylplenolin. 6-O-Methylacrylylplenolin had not been previously isolated from C. minima. All three of these sesquiterpene lactones had activity against Bacillus subtilis and Staphylococcus aureus. A fraction from the methanol extract of Carissa carandas was quite active against herpes simplex virus. This fraction was found to contain a derivative of 3,4,5-trimethoxycinnamic acid.

description: Gratings enable dispersive spectroscopy from the X-ray to the optical, and feature prominently in proposed flagships and SmallSats alike. The exacting performance requirements of these future missions necessitate assessing whether the present state-of-the-art in grating manufacture will limit spectrometer performance. In this work, we manufacture a 1.5 mm thick, 1000 nm period at grating using electron-beam lithography (EBL), a promising lithographic technique for patterning gratings for future astronomical observatories. We assess the limiting spectral resolution of this grating by interferometrically measuring the diffracted wavefronts produced in +/-1st order. Our measurements show this grating has a performance of at least R ~ 14,600, and that our assessment is bounded by the error of our interferometric measurement. The impact of EBL stitching error on grating performance is quantifed, and a path to measuring the period error of customized, curved gratings is presented.

description: We present results of ferromagnetic resonance (FMR) experiments and micromagnetic simulations for a distorted, 2D Kagome artificial spin ice. The distorted structure is created by continuously modulating the 2D primitive lattice translation vectors of a periodic honeycomb lattice, according to an aperiodic Fibonacci sequence used to generate 1D quasicrystals. Experimental data and micromagnetic simulations show the Fibonacci distortion causes broadening and splitting of FMR modes into multiple branches, which accompany the increasing number of segment lengths and orientations that develop with increasing distortion. When the applied field is increased in the opposite direction to the net magnetization of a segment, spin wave modes appear, disappear or suddenly shift, to signal segment magnetization reversal events. These results show the complex behavior of reversal events, as well as well-defined frequencies and frequency-field slopes of FMR modes, can be precisely tuned by varying the severity of the aperiodic lattice distortion. This type of distorted structure could therefore provide a new tool for the design of complicated magnonic systems.

description: We give a simple proof of Lee's result from [Adv.

Our method of proof is entirely local and hence we can state a Lee-type theorem for tangles as well as for knots and links. Our main tool is the "Karoubi envelope of the cobordism category", a certain enlargement of the cobordism category which is mild enough so that no information is lost yet strong enough to allow for some simplifications that are otherwise unavailable.

description: Electromagnetic form factors of hyperons ($Λ$, $Σ$, $Ξ$) in the timelike region, accessible in the reaction $e^+e^- \to \bar YY$, are studied. The focus is on energies close to the reaction thresholds, where the properties of these form factors are significantly influenced by the interaction in the final $\bar YY$ system. This interaction is taken into account in the calculation, utilizing $\bar YY$ potential models that have been constructed by the Jülich group for the analysis of data from the reaction $\bar pp \to \bar YY$ in the past. The enhancement of the effective form factor for energies close to the threshold, seen in experiments of $e^+e^- \to \bar ΛΛ$ and $e^+e^- \to \bar Σ^0Λ$, is reproduced. With regard to the reactions $e^+e^- \to \bar Σ^- Σ^+, \ \barΣ^0Σ^0, \ \barΣ^+Σ^-$ a delicate interplay between the three channels is observed in the results at low energies, caused by the $\barΣΣ$ interaction. Predictions for the electromagnetic form factors $G_M$ and $G_E$ in the timelike region are presented for the $Λ$, $Σ$, and $Ξ$ hyperons.

description: Digital platforms offer vast potential for increased value creation and innovation, especially through cross-organizational data sharing. It appears that SMEs in Germany are currently hesitant or unable to create their own platforms. To get a holistic overview of the structure of the German SME-focused platform landscape (that is platforms that are led by or targeting SMEs), we applied a mixed method approach of traditional desk research and a quantitative analysis. The study identified large geographical disparity along the borders of the new and old German federal states, and overall fewer platform ventures by SMEs, rather than large companies and startups. Platform ventures for SMEs are more likely set up as partnerships. We indicate that high capital intensity might be a reason for that.

A Photometric and Spectroscopic Search for White Dwarfs in the Open Clusters NGC 6633 and NGC 7063

description: We present photometric and spectroscopic studies of the white dwarf (WD) populations in the intermediate-age open clusters NGC 6633 and NGC 7063 as part of the ongoing Lick-Arizona White Dwarf Survey (LAWDS). Using wide-field CCD imaging, we locate 41 candidate WDs in the two cluster fields: 32 in NGC 6633, and 9 in NGC 7063. Spectroscopic observations confirm 13 of these candidates to be bona-fide WDs. We describe in detail our Balmer line fitting technique for deriving effective temperatures and surface gravities from optical DA WD spectra and apply the technique to the 11 DA WDs in the sample. Of these, only two DA WDs are at the cluster distance moduli, one in each cluster. Two more DAs lie 0.75 mag foreground to NGC 6633, raising the possibility that these are double degenerate systems in the cluster. If nearly equal-mass binaries, both of these systems likely have combined masses above the Chandrasekhar limit. One DB WD is found to be consistent with membership in NGC 6633, which would make this the third confirmed He-atmosphere WD in an open cluster, though further data are needed to confirm cluster membership. The WD consistent with membership in the cluster NGC 7063 has a low mass (~0.4 Mo), suggesting it may be a He-core WD resulting from close binary evolution. Three of the eleven hydrogen-atmosphere WDs in this study are observed to have Ca II absorption; the number of DAZs in this study is consistent with previous observations that ~25% of field WDs are DAZs.

Two-Pion Exchange in Proton-Proton Scattering

description: The contribution of the box and crossed two-pion-exchange diagrams to proton-proton scattering at 90$^{\circ}_{c.m.}$ is calculated in the laboratory momentum range up to 12 GeV/c. Relativistic form factors related to the nucleon and pion size and representing the pion source distribution based on the quark structure of the hadronic core are included at each vertex of the pion-nucleon interaction. These form factors depend on the four-momenta of the exchanged pions and scattering nucleons. Feynman-diagram amplitudes calculated without form factors are checked against those derived from dispersion relations. In this comparison, one notices that a very short-range part of the crossed diagram, neglected in dispersion-relation calculations of the two-pion-exchange nucleon-nucleon potential, gives a sizable contribution. In the Feynman-diagram calculation with form factors the agreement with measured spin-separated cross sections, as well as amplitudes in the lower part of the energy range considered, is much better for pion-nucleon pseudo-vector vis à vis pseudo-scalar coupling. While strengths of the box and crossed diagrams are comparable for laboratory momenta below 2 GeV/c, the crossed diagram dominates for larger momenta, largely due to the kinematics of the crossed diagram allowing a smaller momentum transfer in the nucleon center of mass. An important contribution arises from the principal-value part of the integrals which is non-zero when form factors are included. It seems that the importance of the exchange of color singlets may extend higher in energy than expected.

description: As a supplement of our previous work, we consider the localized region of the random Schroedinger operators on $l^2({\bf Z}^d)$ and study the point process composed of their eigenvalues and corresponding localization centers. For the Anderson model, we show that, this point process in the natural scaling limit converges in distribution to the Poisson process on the product space of energy and space. In other models with suitable Wegner-type bounds, we can at least show that any limiting point processes are infinitely divisible.

description: The oxygen evolution reaction (OER) is considered a key reaction for electrochemical energy conversion but slow kinetics hamper application in electrolyzers, metal-air batteries and other applications that rely on sustainable protons from water oxidation. In this review, the prospect of epitaxial perovskite oxides for the OER at room temperature in alkaline media is reviewed with respect to fundamental insight into systematic trends of the activity. First, we thoroughly define the perovskite structure and its parameter space. Then, the synthesis methods used to make electrocatalytic epitaxial perovskite oxide are surveyed, and we classify the different kinds of electrodes that can be assembled for electrocatalytic investigations. We discuss the semiconductor physics of epitaxial perovskite electrodes and their consequences for the interpretation of catalytic results. Prototypical mechanisms of the OER are introduced and comparatively discussed. OER investigations on epitaxial perovskite oxides are comprehensively surveyed and selected trends are graphically highlighted. The review concludes with a short perspective on opportunities for future electrocatalytic research on epitaxial perovskite oxide systems.

description: A state of matter is characterized by its symmetry breaking and elementary excitations. A supersolid is a state which breaks both translational symmetry and internal $ U(1) $ symmetry. Here, we review some past and recent works in phenomenological Ginsburg-Landau theories, ground state trial wavefunctions and microscopic numerical calculations. We also write down a new effective supersolid Hamiltonian on a lattice. The eigenstates of the Hamiltonian contains both the ground state wavefunction and all the excited states (supersolidon) wavefunctions. We contrast various kinds of supersolids in both continuous systems and on lattices, both condensed matter and cold atom systems. We provide additional new insights in studying their order parameters, symmetry breaking patterns, the excitation spectra and detection methods.

Features of information intergation in causal inference
Creators: name: Mandel, David R.
Publisher: name: University of British Columbia
Year: 2009

description: An important aspect of causal inference is assessing the contingency between antecedents and outcomes. Research on how people integrate contingency information has focused on identifying the "best" rule to descriptively model the information integration process. In contrast to this ruleanalytic approach, the present feature-analytic approach asks the question, "What features are important in describing the information integration process?" Five key propositions of the present account are that (a) people prefer strategies that involve contrasting data with conflicting implications to strategies that involve seeking only confirmatory or marginal-frequency data, (b) people weigh positive information more heavily than negative information, (c) people are biased toward testing sufficiency rather than necessity, (d) people are biased toward strategies that cohere with the perceived direction of time (input tests) rather than those that violate this perception (outcome tests), and (e) people are biased toward probability strategies that enable comparability across data contexts rather than frequency strategies that do not. In three experiments, subjects received contingency information on two, temporally sequenced, binary variables in numeric summary format. Subjects were asked to rate the direction and magnitude of the causal relation between the two variables based on the contingency information provided. Results of Experiments 1-3, corroborated by a reanalysis of data from two published experiments employing a discrete-trial method for presenting stimuli, strongly supported the first four propositions. To test the fifth proposition, I reanalyzed data from five published experiments in addition to an analysis of data from Experiment 3. Results indicated that within each data context preferences for either frequency, conditional-probability, or joint-probability strategies emerged, but across contexts consistent preferences for one type of combination method was lacking. Taken together, the findings indicate that invariant properties of the information integration process in causal inference can be isolated but these consist of systematic feature preferences rather than stable rankings of rules in terms of their predictive utility.

The problem of relating the accessory parameters (prevertices together with coefficients in the Schwarzian derivative) to the geometric parameters is solved numerically, including the determination of the parameters for univalence. The study involves the related mapping from an appropriate Euclidean rectangle to the circular-arc quadrilateral. Its Schwarzian derivative involves the Weierstrass P-function, and consideration of this related mapping problem leads to some new formulas concerning the zeroes and the images of the half-periods of P.

description: Magnetic analogue of an isolated free electric charge, i.e., a magnet with a single north or south pole, is a long sought-after particle which remains elusive so far. In magnetically frustrated pyrochlore solids, a classical analogue of monopole was observed as a result of excitation of spin ice vertices. Direct visualization of such excitations were proposed and later confirmed in analogous artificial spin ice (ASI) systems of square as well as Kagome geometries. However, such charged vertices are randomly created as they are thermally driven and are always associated with corresponding emergent antimonopoles of equal and opposite charges connected by observable strings. Here, we demonstrate a controlled stabilisation of a robust isolated emergent monopole state in individual square ASI vertices by application of an external magnetic field. The excitation conserves the magnetic charge without the involvement of a corresponding antimonopole. Well supported by Monte Carlo simulations our experimental results enable, in absence of a true elemental magnetic monopole, creation of electron vortices and studying electrodynamics in presence of a monopole field in a solid state environment.

description: In the late 19th century, Klein inaugurated a program for describing the finite subgroups of $PGL_2(k)$ by treating the case in which the field $k$ is the complex numbers. Gierster and Moore extended Klein's arguments to deal with finite fields. In the past century, additional contributions to this problem were made by Serre, Suzuki, and Beauville, among others. We complete this program by giving a classification of the finite subgroups of $PGL_2(k)$ with order divisible by $p$, up to conjugation, for an arbitrary field $k$ of positive characteristic $p$.

description: In the framework of the electroweak chiral Lagrangian, the one-loop induced effects of the anomalous $tbW$ coupling, which includes both left- and right-handed complex components, on the static electromagnetic properties of the $W$ boson and the $t$ quark are studied. The attention is focused mainly on the CP-violating electromagnetic properties. It is found that the $tbW$ anomalous coupling can induce both CP-violating moments of the $W$ boson, namely, its electric dipole ($\tildeμ_W$) and magnetic quadrupole ($\tilde{Q}_W$) moments. As far as the $t$ quark is concerned, a potentially large electric dipole moment $(d_t)$ can arise due to the anomalous $tbW$ coupling. The most recent bounds on the left- and right-handed parameters from $B$ meson physics lead to the following estimates $\tildeμ_W ~ 10^{-23}-10^{-22}$ e-cm and $\tilde{Q}_W~ 10^{-38}-10^{-37}$ e-cm$^2$, which are 7 and 14 orders of magnitude larger than the standard model (SM) predictions, whereas $d_t$ may be as large as $10^{-22}$ e-cm, which is about 8 orders of magnitude larger than its SM counterpart.

description: The paper is concerned with the change of probability measures $μ$ along non-random probability measure valued trajectories $ν_t$, $t\in [-1,1]$. Typically solutions to non-linear PDEs, modeling spatial development as time progresses, generate such trajectories. Depending on in which direction the map $ν\equivν_0\mapstoν_t$ does not exit the state space, for $t\in [-1,0]$ or for $t\in [0,1]$, quasi-invariance of the measure $μ$ under the map $ν\mapstoν_t$ is established and the Radon-Nikodym derivative of $μ\circν_t$ with respect to $μ$ is determined. It is also investigated how Fréchet differentiability of the solution map of the PDE can contribute to the existence of this Radon-Nikodym derivative. The first application is a certain Boltzmann type equation. Here the Fréchet derivative of the solution map is calculated explicitly and quasi-invariance is established. The second application is a PDE related to the asymptotic behavior of a Fleming-Viot type particle system. Here quasi-invariance is obtained and it is demonstrated how this result can be used in order to derive a corresponding integration by parts formula.

description: Children born preterm often experience poorer psychological outcomes at each developmental life stage compared to full-term peers. However, this vulnerable population is often considered remarkable for their resilience in the face of adversity. To examine difficulties in psychological wellbeing and establish possible patterns of resilience with the preterm population, this study uses data from the prospective Longitudinal Study of Australian Children (LSAC) to assess the association between prematurity and the stability of internalising problems from 10-11 to 14-15 years. The study investigates the interacting effects of gestational period, gender and parental warmth on the stability of severity of internalising problems following the transition to adolescence. Data from 44 very preterm (VPT), 195 moderate preterm (MPT) and 2851 term born adolescent participants in the LSAC was used. Gestational period was found to be predictive of resilience, with durations less than 32 weeks associated with increased internalising difficulties during the transition to adolescence compared to non-preterm and moderate preterm. Gender moderated the association between gestational age and increased internalising problems with very preterm female adolescents encountering the highest internalising psychopathology and the greatest magnitude of change between middle childhood and adolescence. Parental warmth was not predictive of stability of psychological wellbeing in preterm respondents. These findings may help inform early intervention practices for preterm populations in boosting child coping capacities and peer and parent support prior to adolescence, and prompt further research into the mechanisms driving the distinct pattern of psychological resilience of females born very prematurely.

description: Motivated by ongoing experimental efforts to make closed Bose-Einstein condensate (BEC) shells in microgravity environments, this work studies the energy and dynamics of singly quantized vortices on a thin spherical superfluid shell, where the overall vortex charge must vanish (as on any compact surface). For each vortex, stereographic projection yields the corresponding complex potential on the tangent plane. The resulting stream function then provides both the total energy and the dynamics of a system of overall neutral vortices on a spherical film. Although a single vortex dipole follows a simple dynamical orbit, four vortices can present a variety of situations. We study a few symmetric initial configurations and then focus on the special case of two small vortex dipoles.

Description
LAST-STAGE NAUPLIUS (LSN). Lecithotrophic. Body narrowly ovate in dorso-ventral view; about twice as long as wide; lateral margins tapering gradually towards caudal end with no discontinuity at posterior end of cephalic shield. In lateral view, trunk axis downturned ca 30–45° relative to cephalic axis. Length 310–360 µm (without dorso-caudal spine), greatest width 170 µm, greatest dorso-ventral thickness 60–70 µm. Labrum weakly elevated, approximately as long as wide and sub-pentagonal in outline; surface not obviously divided into facets by cuticular ridges; bearing five pores: row of three in midline posteriorly and pair situated at lateral margins on right and left sides. Body terminating in long (ca 50 µm, width at base ca 12 µm), straight, smooth or weakly terraced dorso-caudal spine with long axis either in same plane as trunk axis or upturned ca 20° relative to latter and pair of shorter but still prominent (15–20 µm), fairly sharp, dorsally or dorso-medially curved furcal spines.
CYPRID VIEWED THROUGH CUTICLE OF LSN. Body overall markedly brownish-pigmented. Orange yolk granules seen most clearly in cephalon and telson, sometimes also concentrated centrally in body but often more widely distributed. Telson of variable outline in ventral view, as long as wide or longer, approximately half as long as thorax.
Identification and variation
Easily recognizable by the combination of its brown coloration and somewhat extended overall body shape, the lengths of the three caudal spines and (at least in some) the obvious medial component of the furcal spines’ curvature. Morphological variation among specimens in body size, the angle between the dorso-caudal spine and the hind-body, and the size and degree of curvature of the furcal spines suggests that more than one species may be involved. The molecular diversity of 13 specimens sequenced by Dreyer et al. (2023a) also suggests that this morphospecies consists of two or three separate species.
Distribution
Japan (Sesoko Island, Okinawa), Taiwan (Wanghaixiang Fishing Harbour, Keelung).

description: We establish two precise asymptotic results on the Birkhoff sums for dynamical systems. These results are parallel to that on the arithmetic sums of independent and identically distributed random variables previously obtained by Hsu and Robbins, Erdős, Heyde. We apply our results to the Gauss map and obtain new precise asymptotics in the theorem of Lévy on the regular continued fraction expansion of irrational numbers in $(0,1)$.

Land-use and water quality : a GIS evaluation of the problems, interaction, and initiatives, in the Pampanga River Basin, Central Luzon, Philippines

description: Agricultural activities in the Pampanga river Basin (PRB) are threatened by the increasing population and development thrusts of the Philippine government. This study was conducted to develop a framework by which problems, initiatives, and interactions among land-use changes, water quality and governance issues may be assessed employing Geographic Information Systems (GIS) techniques. Stream stations were sampled for nitrate, phosphate, temperature, dissolved oxygen, total dissolved solids, chemical oxygen demand and pH. Land-use changes were analyzed through GIS, while land-use planning was investigated through workshop participation and review of government plans. Agricultural land increased 0.6% annually from 1953 to 1980 due to conversion of grasslands, wetlands and forests to agriculture, and declined 0.5 % annually from 1980 to 1993 due to expansion of settlements. A provincial land-use plan would accelerate conversion rather than protect agricultural lands. Water quality in the Pampanga river and its tributaries is deteriorating in both the spatial and temporal dimensions. The eruption of Mt. Pinatubo was responsible for increased levels of ortho-phosphate, TDS, and temperature in streams, but the low DO during the start of the rainy season and the high nitrate-N concentrations are indicators of human influence on water quality. Streams with catchments having the same predominant land-use classification exhibited similar trends in water quality. Animal species in different area classifications also affected water quality at different flow periods. Buffer analysis on 500 metre zone along the streams gave best values. The effect of runoff is altered by the type of land-use, specifically the presence of rice fields. The management of nitrate-N based on a nitrogen budget revealed that animal manure and inorganic fertilizer are major sources of nitrogen in the basin. The hotspot areas are catchments with large settlement areas, and/or with a very high animal population. Alternative scenarios revealed no significant changes in water quality even with a three-fold increase in animal production or 10 % agricultural land conversion. A cautious optimism is anticipated in involving the barangay captains in the overall management of the environment, in particular, the control of stream pollution that endangers the fishing industry.

description: We construct black hole attractor solutions for a wide class of N=2 compactifications. The analysis is carried out in ten dimensions and makes crucial use of pure spinor techniques. This formalism can accommodate non-Kaehler manifolds as well as compactifications with flux, in addition to the usual Calabi-Yau case. At the attractor point, the charges fix the moduli according to sum_k f_k = Im(C Phi), where Phi is a pure spinor of odd (even) chirality in IIB (A). For IIB on a Calabi-Yau, Phi=Omega and the equation reduces to the usual one. Methods in generalized complex geometry can be used to study solutions to the attractor equation.

description: Let X_1, X_2 be symplectic 4-manifolds containing symplectic surfaces F_1,F_2 of identical positive genus and opposite squares. Let Z denote the symplectic sum of X_1 and X_2 along the F_k. Using relative Gromov--Witten theory, we determine precisely when the symplectic 4-manifold Z is minimal (i.e., cannot be blown down); in particular, we prove that Z is minimal unless either: one of the X_k contains a (-1)-sphere disjoint from F_k; or one of the X_k admits a ruling with F_k as a section. As special cases, this proves a conjecture of Stipsicz asserting the minimality of fiber sums of Lefschetz fibrations, and implies that the non-spin examples constructed by Gompf in his study of the geography problem are minimal.
