The Stability of the Cosmological System of Degenerate Scalar Charged Fermions and Higgs Scalar Fields. II. The Evolution of Short-Wave Perturbations

description: A mathematical model of the evolution of plane perturbations in the cosmological statistical system of completely degenerate scalar-charged fermions with Higgs scalar interaction for short-wave perturbations is formulated. These disturbance modes have been found and investigated. It is shown that in such a model an additional oscillation mode arises, which is associated directly with degenerate fermions, in which monotonically decreasing and increasing perturbations of the metric exist. In this case, there is such a time instant in the system that the potential of the scalar field, together with the energy density, tends to infinity. In this regard, an assumption is made about a possible mechanism for the formation of dark matter condensates.

description: The silicon pixel detector of the ALICE experiment at LHC comprises the two innermost layers of the inner tracking system of the apparatus. It contains 1200 readout chips, each of them corresponding to a 8192 pixel matrix. The single chip outputs a digital Fast-OR signal which is active whenever at least one of the pixels in the matrix records a hit. The 1200 Fast-OR output signals can be used to implement a unique triggering capability: few details on the pixel trigger system and some of the possible applications for p-p collisions are presented.

Energetics of Electron Transfer and Charge Separation in Moderate to Low Polarity Solvents
Creators: name: Albert, Brian R
name: Miller, John R
Publisher: name: Columbia Undergraduate Science Journal
Year: 2009

description: The absorption of light in natural photosynthesis occurs in a low polarity region allowing photoelectrons to store absorbed energy in chemical bonds instead of emitting heat via solvent interaction. Consequently, studying electron transfer and charge separation in low polarity solvents may have application in solar energy storage as such a study will make electron transfer in low polarity become more thoroughly understood. Conducted in solvents of various dielectric constants, the study combines strong electron donors and electron acceptors to promote ion formation by thermal equilibria. The extent to which these molecules formed ion pairs and free ions was measured via conductivity and UV-Vis spectroscopy. Gibbs free energy changes were calculated for ion formation and separation using acetonitrile as a standard highly polar solvent. With values of ionization potentials and electron affinities, free energy changes observed in the moderately polar solvent, tetrahydrofuran, were fit to theoretical Born solvation and Coulomb potential models by determining effective ion radii. Model predictions for free energy changes in other solvents disagreed with experimental data because unexpected charge transfer complexes become significant in concentration. Approximations of free energy changes were difficult in low polarity solvents due to low conductivity measurements and charge transfer complexes that appear in UV-Vis absorption spectra. Observed free energy changes were found to be significantly less favorable than redox potentials of the same reactions determined electrochemically not in this study. The difference is attributed to the unintended stabilization of ions caused by salt in solution required for the electrochemical method.

Towards a description of low-energy hadronic physics using the Skyrme model
Creators: name: Pari, Giovanni
Publisher: name: University of British Columbia
Year: 2011

description: We prove that the generalization of the Skyrme quartic lagrangian from flavor SU(2) to flavor SU(3) is not unique. Under the general assumptions of chiral symmetry, Lorentz invariance and restriction to two time—derivatives, there are two independent SU(3) forms. We apply within the framework of the Yabu and Ando approach, the new "alternate" lagrangian to a calculation of octet and decuplet baryon mass differences and find good agreement with experiment. We consider the alternate lagrangian to construct an eta-nucleon bound state model for the N(1535) resonance. Also, we have considered the problem of describing the S and P wave π-nucleon scattering within the framework of the Skyrme model. We go beyond the adiabatic approximation by considering the introduction of time—derivative interactions between pions and collective coordinates. A truncation scheme of unphysically open channels is introduced in K-matrix formalism and a unitary S-matrix is reconstructed. We compare our results with the ∆-isobar model and with phase shift analyses. Our calculation reproduces well the essential features of the P waves. For S waves, very attractive background contributions lead to poor agreement with the phase shift data.

description: We present the first X-ray observations of three sources belonging to a new AGN class: the naked AGNs. Based on optical spectroscopic studies, these sources appear as classical type 2 (obscured) AGNs, with only narrow emission lines. However, long-term optical monitoring campaigns, carried out over more than two decades, show that the same sources are strongly variable, like type 1 (un-obscured) AGNs. Based on short Chandra observations, the sources appear to be fairly bright in the X-rays, with typical Seyfert 1s values for the photon index (Gamma~1.8) and without significant intrinsic absorption, supporting the conclusion that some bright AGNs may genuinely lack a broad line region. Future, broad-band studies as well as deeper X-ray observations, probing both the spectral and the temporal properties of the naked AGNs, are crucial to shed light on the central engine of these sources, which may be representative of a large class of AGNs.

description: Folklore has, that the universal scaling properties of linear polymers in disordered media are well described by the statistics of self-avoiding walks Folklore has, that the universal scaling properties of linear polymers in disordered media are well described by the statistics of self-avoiding walks (SAWs) on percolation clusters and their critical exponent $ν_{\text{SAW}}$, with SAW implicitly referring to \emph{average} SAW. Hitherto, static averaging has been commonly used, e.g. in numerical simulations, to determine what the \emph{average} SAW is. We assert that only kinetic, rather than static, averaging can lead to asymptotic scaling behavior and corroborate our assertion by heuristic arguments and a renormalizable field theory. Moreover, we calculate to two-loop order $ν_{\text{SAW}}$, the exponent $ν_{\text{max}}$ for the longest SAW, and a new family of multifractal exponents $ν^{(α)}$.

description: Unsupervised Domain Adaptation (UDA) refers to the problem of learning a model in a target domain where labeled data are not available by leveraging information from annotated data in a source domain. Most deep UDA approaches operate in a single-source, single-target scenario, i.e. they assume that the source and the target samples arise from a single distribution. However, in practice most datasets can be regarded as mixtures of multiple domains. In these cases, exploiting traditional single-source, single-target methods for learning classification models may lead to poor results. Furthermore, it is often difficult to provide the domain labels for all data points, i.e. latent domains should be automatically discovered. This paper introduces a novel deep architecture which addresses the problem of UDA by automatically discovering latent domains in visual datasets and exploiting this information to learn robust target classifiers. Specifically, our architecture is based on two main components, i.e. a side branch that automatically computes the assignment of each sample to its latent domain and novel layers that exploit domain membership information to appropriately align the distribution of the CNN internal feature representations to a reference distribution. We evaluate our approach on publicly available benchmarks, showing that it outperforms state-of-the-art domain adaptation methods.

description: Increased multi-level omics data have enabled data-driven studies on cancer drugs, targets and biomarkers. Thus, it is necessary to develop comprehensive tools for oncologists and cancer scientists to carry out extensive data mining without computational expertise. For this purpose, we have developed innovative software that enables user-driven analyses on cancer omics data, assisted by knowledge-based smart systems. Publicly available multi-level omics data of mutations, gene/protein expression, patient survival, immune score (tumor infiltrating cells), drug screening and RNAi (shRNA and CRISPR) screenings on patient samples and cell lines, were integrated from the TCGA, GDSC, CCLE, NCI and DepMap databases. Q-omics provides user-friendly interface for calculation and visualization of cross-associated data pairs retrieved from integrated datasets. The optimal selection of samples, datasets and/or other filtering options is guided by knowledge-bases of the software for the quick and easy finding of significant associations between data pairs. Furthermore, implemented smart algorithms prioritize significant hits based on consensus scoring methods. Consensus scoring using multiple statistical tests with varied sample (or lineage) selection, enriches noise-free, robust cross-associated pairs in the hit list. We believe that Q-omics provide simple but powerful tools for all areas of oncology and cancer research. The latest version of Q-omics software is available at http://qomics.sookmyung.ac.kr.

description: A room-temperature beam of krypton atoms in the metastable 5s[3/2]2 level is demonstrated via an optical excitation method. A Kr-discharge lamp is used to produce VUV photons at 124 nm for the first-step excitation from the ground-level 4p6 1S0 to the 5s[3/2]1 level. An 819 nm Ti:Sapphire laser is used for the second-step excitation from 5s[3/2]1 to 5p[3/2]1, followed by a spontaneous decay to the 5s[3/2]2 metastable level. A metastable atomic beam with an angular flux density of 3 x 10^14 /s/sr is achieved at the total gas flow rate of 0.01 cm^3 STP/s (or 3 x 10^17 atoms/s). The dependences of the flux on the gas flow rate, laser power, and lamp parameters are investigated.

description: Infrared combination bands of the polar isomer of the N2O dimer are observed for the first time, using a tunable infrared laser source to probe a pulsed slit-jet supersonic expansion in the N2O nu1 region (~2240 cm-1). One band involves the torsional (out-of-plane) intermolecular mode and yields a torsional frequency of 19.83 cm-1 if associated with the out-of-phase fundamental (N2O nu1) vibration of the N2O monomers in the dimer. The other band, which is highly perturbed, yields an intermolecular in-plane geared bend frequency of 22.74 cm-1. The results are compared with high level ab initio calculations. The less likely alternate assignment to the in-phase fundamental would give torsional and geared bend frequencies of 17.25 and 20.16 cm-1, respectively.

Accumulating a large number of statistics by the averages over 16 different source points and over forward and backward nucleon propagators, we have obtained non-zero signals of neutron and proton EDM beyond one standard deviation at each quark mass in full QCD. We have investigated the quark mass dependence of nucleon EDM in full QCD, and have found that nucleon EDM in full QCD does not decrease toward the chiral limit, as opposed to the theoretical expectation. We briefly discuss possible reasons for this behavior.

Landscaping prognostic gene expression and anticancer targets using sample and lineage consensus scores derived from pan-cancer omics data

description: Integration of large scale multi-omics data enables extensive analysis of cross-associated data pairs between collateral datasets such as mutation, RNA/protein expression, RNAi/drug screen, clinical information, etc. Here, we investigated the reproducibility of the significance in the association by measuring sample consensus and/or lineage consensus for given data pairs (gene expression vs. patient survival, gene expression vs. RNAi efficacy). The sample consensus score represents the number of significant (p<0.01) cases in the associations for a given data pair among varied sample groups within a lineage, while the lineage consensus score is the significant cases among diverse lineages.
 ~74% of prognostic gene expression (i.e., gene expression associated with patient survival) were exclusively found in a single lineage, while only ~1.8% prognostic genes showed the significance in over three different lineages (consensus score >3). In case of sample consensus, common prognostic genes between genders were less than exclusive genes between them. However, prognostic genes with high sample consensus score generally exhibited high lineage consensus scores, implying that consensus scoring might improve the reproducibility of predicted prognostic gene expression in other cohort or cancer lineages. Furthermore, the lineage consensus score for the association between sgRNA (CRISPR) efficacy and RNA expression could predict the association between shRNA and RNA expression.
 This study suggests that consensus scoring help smart data mining prioritizing true-positives for the further validation. The concept of consensus scoring has been implemented in Q-omics software (http://qomics.sookmyung.ac.kr) for analyzing associations between diverse cancer omics data.
Icy Exomoons Evidenced by Spallogenic Nuclides in Polluted White Dwarfs

description: We present evidence that excesses in Be in polluted white dwarfs (WDs) are the result of accretion of icy exomoons that formed in the radiation belts of giant exoplanets. Here we use excess Be in the white dwarf GALEX J2339-0424 as an example. We constrain the parent body abundances of rock-forming elements in GALEX J2339-0424 and show that the overabundance of beryllium in this WD cannot be accounted for by differences in diffusive fluxes through the WD outer envelope nor by chemical fractionations during typical rock-forming processes. We argue instead that the Be was produced by energetic proton irradiation of ice mixed with rock. We demonstrate that the MeV proton fluence required to form the high Be/O ratio in the accreted parent body is consistent with irradiation of ice in the rings of a giant planet within its radiation belt, followed by accretion of the ices to form a moon that is later accreted by the WD. The icy moons of Saturn serve as useful analogs. Our results provide an estimate of spallogenic nuclide excesses in icy moons formed by rings around giant planets in general, including those in the solar system. While excesses in Be have been detected in two polluted WDs to date, including the WD described here, we predict that excesses in the other spallogenic elements Li and B, although more difficult to detect, should also be observed, and that such detections would also indicate pollution by icy exomoons formed in the ring systems of giant planets.

Photosynthesis and respiratory acclimation in Quercus rubra L. along an urban-to-rural temperature gradient

Publisher: name: Columbia Undergraduate Science Journal
Year: 2009

description: The role of the terrestrial biosphere as a carbon sink or source is a critical and still poorly understood component of predicting global climate change. In particular, the response of plant respiration (R) to temperature remains a major uncertainty in current prediction models. Using a natural nighttime temperature gradient from New York City to surrounding rural areas, we investigated R rates in common red oak (Quercus rubra L.). Oaks were grown from seed at four sites along an urban to rural gradient as well as in growth chambers. We measured rates of photosynthesis and R in five one-year-old seedlings at each site. Leaves from mature trees along the gradient were also sampled for short-term response of R to temperature. Photosynthetic rates in seedlings did not differ significantly between sites. R in seedlings was lowest in NYC and progressively higher at increasing distances from the city, indicating respiratory acclimation along the gradient. In contrast, results from growth chambers and mature trees exhibited reverse acclimation with higher rates of R in plants grown at elevated temperatures. While there is some evidence to suggest the occurrence of respiratory acclimation to temperature along the gradient, more research is required before a definitive conclusion can be made.

Shot noise in diffusive ferromagnetic metals

description: We show that shot noise in a diffusive ferromagnetic wire connected by tunnel contacts to two ferromagnetic electrodes can probe the intrinsic density of states and the extrinsic impurity scattering spin-polarization contributions in the polarization of the wire conductivity. The effect is more pronounced when the electrodes are perfectly polarized in opposite directions. While in this case the shot noise has a weak dependence on the impurity scattering polarization, it is strongly affected by the polarization of the density of states. For a finite spin-flip scattering rate the shot noise increases well above the normal state value and can reach the full Poissonian value when the density of states tends to be perfectly polarized. For the parallel configuration we find that the shot noise depends on the relative sign of the intrinsic and the extrinsic polarizations.

Multiphase structure of finite-temperature phase diagram of the Blume-Capel model. Wang-Landau sampling method

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: We investigate the density of states (DOS) in an antiferromagnetic spin-system on a square lattice described by the Blume-Capel (BC) model. We use a new and very efficient simulation method, proposed by Wang and Landau, in which we estimate very precisely DOS by sampling in the space of energy. Then we calculate the thermodynamical averages like internal energy, free energy, specific heat and entropy. The BC model exhibits multicritical behaviour such as first- or second-order transitions and tricritical points. It is known that the ground state of the model can exhibit two kinds of staggered antiferromagnetic phases: AF1 (two interpenetrating lattices with S = -1 and S = 1) and AF2 (S = -1 and S = 0 for H < 0; S = 1 and S = 0 for H > 0). We analyze the coexistence of such phases at finite temperatures and determine border lines between them. To understand the microscopic nature of such boundaries we present also some results obtained with the standard Monte Carlo method.

Following Edgard Varese's Hyperprism, Pierre Boulez's Improvisation sur Mallarme II, and Elliot Carter's Second String Quartet, Variations V contrasted greatly in composition and media with the pieces of the first half of the Philharmonic's program. Instead of orchestral instrumentalists performing live on their trumpets, cellos, and violins, recorded and radio sounds filled the concert hall through six speakers "distributed around Philharmonic Hall" (Hughes "Leaps" 1965:10); the choreographed movements of seven dancers occupied the stage; and filmed images projected on a screen behind them. The performance was an over-whelming multimedia display, with no immediate connection between the various modes of artistic expression.

Measurement of shock-induced luminescence in silicon
Creators: name: Xu, Guang
Publisher: name: University of British Columbia
Year: 2010

description: Shock induced luminescence in silicon was measured with a time resolution of 20 ps. Polished silicon wafers were irradiated with 0.53μm laser light in a pulse of 2.7 ns FWHM at intensities ranging from 2 x 10¹⁷W/m² to 5 x 10¹⁷W/m². This produced a strong shock in the solid. The shock speeds were determined by measuring the shock transit times through targets of different thickness (68μm and 82 μm). The corresponding shock pressure was found to range from 3 Mbar to 6 Mbar. Shock induced luminescence at wavelengths of 430nm and 570nm were recorded using a streak camera which was calibrated for ablsolute response. Substantial disagreement was observed between the luminosity data and the theoretical prediction which assumes thermal equilibrium between electrons and ions in the shock wave. An electron-phonon thermal relaxation model was proposed which treated the processes of both equilibration and thermal diffusion in an electron temperature gradient behind the shock front. Calculations including such a gradient yielded good agreements with data. The electron-phonon coupling constant g in shock-compressed Si was estimated to be 10¹⁷Wmˉ³Kˉ¹ in the pressure range of interest.
Extraction of cartographic objects in high resolution satellite images for object model generation

description: The aim of this study is to detect man-made cartographic objects in high-resolution satellite images. New generation satellites offer a sub-metric spatial resolution, in which it is possible (and necessary) to develop methods at object level rather than at pixel level, and to exploit structural features of objects. With this aim, a method to generate structural object models from manually segmented images has been developed. To generate the model from non-segmented images, extraction of the objects from the sample images is required. A hybrid method of extraction (both in terms of input sources and segmentation algorithms) is proposed: A region based segmentation is applied on a 10 meter resolution multi-spectral image. The result is used as marker in a "marker-controlled watershed method using edges" on a 2.5 meter resolution panchromatic image. Very promising results have been obtained even on images where the limits of the target objects are not apparent.

Our methodology is based on an integration of robust optimization, more specifically a recent line of research known as distributionally robust optimization, and importance sampling in Monte Carlo simulation. The main computation machinery in this integrated methodology amounts to solving sampled linear programs. We present theoretical statistical guarantees of our approach via connections to nonparametric hypothesis testing, and numerical performances including parameter calibration and downstream decision and risk evaluation tasks.

Year: 2010

description: In her interview in Pink Noises, DJ Rekha Malhotra says, "Electronic music is such a vast landscape" (173). To one person, "electronic music" can mean the bhangra-influenced sounds that DJ Rekha produces in her sets; to another, music influenced by musique concrete; and to yet another, circuit bending or the use of synthesizers such as the ARP 2500 and the Buchla. "Electronic music" describes music produced in a variety of social and temporal con-texts, from composer Kaffe Matthews performing subtle electro acoustic compositions in the darkest rooms she can find in order to "make music that is completely about listening and is not about watching," (39) to feminist dance punk band Le Tigre playing their sequenced and sampled pop-oriented, feminist music to dancing indie-rock crowds. These vastly different styles, contexts, and practices come together in Tara Rodgers's book, a collection of twenty-four interviews with women composers, producers, and practitioners of electronic music. Through these interviews, Rodgers moves fluidly between musical styles and practices in ways that illustrate the extensive involvement of women as creators of electronic music from the 1950s to the present and that make a strong counter-argument to popular and academic histories that have often relegated women's contributions to the arena of performance.

description: We consider a continuous analogue of the simulated annealing algorithm in $R^d$. We prove a convergence result, under hypotheses weaker than the usual ones. In particular, we cover cases where the gradient of the potential goes to zero at infinity. The proof follows an idea of L. Miclo, but we replace the Poincaré and log-Sobolev inequalities (which do not hold in our setting) by weak Poincaré inequalities. We estimate the latter with measure-capacity criteria. We show that, despite the absence of a spectral gap, the convergence still holds for the "classical" schedule t = c/ ln(t), if c is bigger than a constant related to the potential.

description: Abstract

Green product demand increases as consumers become more conscious of the world's worsening environmental problems. This study investigates the impact of green product demand on brand performance. Despite the attention paid by FMCG firms in Nigeria to green product demand (green product design and green promotion), brand reputation still needs to improve. The study used a descriptive survey approach, using 121 workers from the identified firms as participants. The total sample size for the research was 121. A systematic questionnaire was used to obtain information from respondents using primary data. In addition, Cronbach's alpha and the Statistical Package for Social Sciences (SPSS) version 20.00 were used in this study to regress the data obtained from the respondents. The results show that green product demand [green product design (.01+2.24) and green advertising (.01+1.41)] had a positive and significant impact on FMCG brand performance (brand reputation) in Nigeria. Based on this finding, the study recommends that the chosen FMCG's managers and quality control department continue to use green product demand to improve brand performance. This is the new method of getting product consumers to be more patriotic by helping build a better brand reputation for the organisation. Furthermore, FMCG in Nigeria should continue to improve their green design and use green advertising to attract more customers to their product since it is favourably associated with it.

description: We investigate effects of field theory instantons by considering D-instantons in a suitable D3-brane background. In supersymmetric QCD with SU(N_c) gauge group with N_f=N_c flavors, the moduli space of vacua is deformed by instantons. This effect can be described by the chiral interactions which are called multi-fermion F-terms. We derive these chiral interaction terms as D-instanton effects in the presence of D3-branes. For SU(2), the obtained result agrees with the previous result worked out by Beasley and Witten [hep-th/0409149]. We also explicitly work out those for the case of the symplectic gauge group, and show that they describe the deformation of the moduli space.

MRI analysis of medial temporal lobe atrophy vs. psychometric biomarkers of Alzheimer's disease

description: Psychometric biomarkers have been used to predict Alzheimer’s disease (AD), but due to subjectivity and ambiguity, they can lack accuracy. Neuroimaging such as magnetic resonance imaging (MRI) provides a fast, objective, and effective means to monitor AD progression. The development of AD occurs in stages; however, the most salient clinical manifestation is a decline in cognitive functioning. To indicate which early screening technique more accurately predicts cognitive decline and further progression to AD, the specificity and sensitivity of psychometric versus MRI biomarkers is compared. In this study, we show that specific tissue loss assessed by anatomical scans in the medial temporal lobe (MTL) occurs early in AD pathology and that analysis of this atrophy can be used to predict future clinical and cognitive decline in normal subjects (NL) and subjects with mild cognitive impairment (MCI). Stable subjects (NL–>NL: n=32) and decliners (NL–>MCI: n=22, NL–>AD: n=4, and MCI–>AD: n=2) completed a standardized longitudinal protocol including history, physical, clinical laboratory with ApoE4 allele screening, neurological and neuropsychological evaluations, and two high-resolution MRI examinations. Observation period ranged from 5.1 to 13.2 years. Baseline and follow-up MRI images were co-registered and the annual rate of brain tissue atrophy within the MTL and whole brain was calculated using the boundary shift algorithm. Binary logistic regression was applied to calculate sensitivity, specificity, and accuracy of neuroimaging and psychometric predictors. The results corroborate the application of MRI analysis techniques as surrogate markers of Alzheimer’s disease; however, validation of this technique, with postmortem AD case verification, is warranted.

social network analysis

description: Do you have problems connecting with colleagues that can answer your questions? Do you ever find yourself in a situation where you aren’t sure who can address a particular knowledge gap? Do you expect network development activities to occur organically? Have you ever wondered what a sociogram is or how to create one? If you answered yes to any of these questions, come discover the process of social network analysis (SNA) and how you can use it to more intentionally develop the network of individuals that support you in carrying out your daily job responsibilities.

Suppression of weak-localization (and enhancement of noise) by tunnelling in semiclassical chaotic transport

description: We add simple tunnelling effects and ray-splitting into the recent trajectory-based semiclassical theory of quantum chaotic transport. We use this to derive the weak-localization correction to conductance and the shot-noise for a quantum chaotic cavity (billiard) coupled to $n$ leads via tunnel-barriers. We derive results for arbitrary tunnelling rates and arbitrary (positive) Ehrenfest time, $τ_{\rm E}$. For all Ehrenfest times, we show that the shot-noise is enhanced by the tunnelling, while the weak-localization is suppressed. In the opaque barrier limit (small tunnelling rates with large lead widths, such that Drude conductance remains finite), the weak-localization goes to zero linearly with the tunnelling rate, while the Fano factor of the shot-noise remains finite but becomes independent of the Ehrenfest time. The crossover from RMT behaviour ($τ_{\rm E}=0$) to classical behaviour ($τ_{\rm E}=\infty$) goes exponentially with the ratio of the Ehrenfest time to the paired-paths survival time. The paired-paths survival time varies between the dwell time (in the transparent barrier limit) and half the dwell time (in the opaque barrier limit). Finally our method enables us to see the physical origin of the suppression of weak-localization; it is due to the fact that tunnel-barriers ``smear'' the coherent-backscattering peak over reflection and transmission modes.

description: The problem A number of tree species in the genus Eucalyptus L’Her are grown in New Zealand on a small scale. However, the economic value of this resource is not known. The economic impact of damage caused by a pest, the eucalyptus tortoise beetle (Paropsis charybdis), to Eucalyptus species in grown in New Zealand is also not defined. The current approach The standing Eucalyptus crop in New Zealand was valued in terms of projected yield and other ecosystem services. Also, the cost of Paropsis charybdis damage to Eucalyptus forests was estimated along with the costs and benefits of chemical and biological control of this pest. Key results The total planted area of Eucalyptus species in New Zealand was estimated to be 27,598 ha with a standing volume of 8.1 million m3 , with a conservative asset value of $671 million. This could be increased in the future if higher value products (e.g. wood flooring or ground-durable poles) are produced from the existing Eucalyptus estate and future plantings. Paropsis charybdis shows a strong feeding preference for Eucalyptus nitens, which is the major species grown for the production of wood chips for paper making. Paropsis charybdis finds many species in the eucalypt sub-genus Symphyomyrtus palatable but all show different susceptibility to the pest. We know the proportion of susceptible species in different stands will differ between regions. Regional forest inventory data from the Ministry for Primary Industries (MPI 2016) was examined and combined with Scion in-house species-site matching knowledge to estimate the proportion of Eucalyptus species in each region that might be palatable to P. charybdis. From this exercise, the weighted average across New Zealand of Eucalyptus plantations susceptible to P. charybdis was estimated at 60-75%. Therefore, $402-$503 million worth of Eucalyptus stands have a high potential of being damaged by P. charybdis.
The Magnificent Seven: Magnetic fields and surface temperature distributions

description: Presently seven nearby radio-quiet isolated neutron stars discovered in ROSAT data and characterized by thermal X-ray spectra are known. They exhibit very similar properties and despite intensive searches their number remained constant since 2001 which led to their name ``The Magnificent Seven''. Five of the stars exhibit pulsations in their X-ray flux with periods in the range of 3.4 s to 11.4 s. XMM-Newton observations revealed broad absorption lines in the X-ray spectra which are interpreted as cyclotron resonance absorption lines by protons or heavy ions and / or atomic transitions shifted to X-ray energies by strong magnetic fields of the order of 10^13 G. New XMM-Newton observations indicate more complex X-ray spectra with multiple absorption lines. Pulse-phase spectroscopy of the best studied pulsars RX J0720.4-3125 and RBS 1223 reveals variations in derived emission temperature and absorption line depth with pulse phase. Moreover, RX J0720.4-3125 shows long-term spectral changes which are interpreted as due to free precession of the neutron star. Modeling of the pulse profiles of RX J0720.4-3125 and RBS 1223 provides information about the surface temperature distribution of the neutron stars indicating hot polar caps which have different temperatures, different sizes and are probably not located in antipodal positions.
