Non Photochemical Quenching mechanism in higher plants and in the unicellular alga Chlamydomonas reinhardtii
Creators: name: Guadagno, Carmela Rosaria
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: Light is a necessary ecological factor for oxygenic photoautotrophic organisms. Plants and algae require light for life but it can sometimes become a limiting factor or even cause stress events. Among the different mechanisms evolved to cope with excessive light, the Non Photochemical Quenching (NPQ) seems to be the most efficient process in both plants and algae. The NPQ value can be attributed to three different components (qE, qT and qI). A central problem for eco – physiology is the quantification of the partitioning of the excitation energy into the different mechanisms.
To investigate the variability in the extent of the three components on external parameters, different experiment were performed. My research showed that utilizing inhibitors or mutants lines of Arabidopsis a variation in the components was inducted. The analysis of the fluorescence parameters were further developed and in this work a revised energy partition approach will be proposed.
Moreover, seen that it is very important avoid light stress situation this research proposed the NMR (Nuclear Magnetic Resonance) as a useful tool in the detection of stress situation in vegetal extracts.
In regard to Chamydomonas reinhardtii not so many information are collected on the NPQ. Interestingly, analyses of a suppressor of the npq4 mutation seemed to partly restore the wild-type
NPQ value. This suggests a role not only for protein LHCS3 , but also for LHCSR1.

Sviluppo di nuove molecole che modulano l'attività di sistemi coinvolti nell'angiogenesi

description: [ITALIANO] L’angiogenesi è un processo essenziale per la crescita dei tumori solidi; è stato dimostrato che la soppressione anche di una sola delle fasi che la costituiscono può inibire la formazione di nuovi vasi sanguigni, influenzando la crescita tumorale e la formazione di metastasi.
Scopo di questo lavoro è stato lo sviluppo di nuove molecole in grado di modulare l’attività di sistemi coinvolti nel processo angiogenico. A tal fine sono stati scelti due sistemi tra quelli più noti e studiati nell’ambito della regolazione del processo angiogenico: il recettore per le proteine della matrice integrina αVβ3 e il fattore di crescita vascolare endoteliale VEGF.
Per quanto riguarda l’integrina αVβ3, è stata progettata e sintetizzata una nuova molecola bifunzionale di natura peptidica, denominata RGDechi, con attività inibitoria nei confronti dell’integrina in esame per la quale si è dimostrata non solo affine ma anche selettiva. Questa molecola potrebbe fungere da lead compound per lo sviluppo di nuovi agenti anti-tumorali e/o di una nuova classe di traccianti non-invasivi da impiegare per il targeting dei recettori αVβ3.
Per quanto riguarda il VEGF, sono stati sviluppati antagonisti sintetici di tale proteina mediante impiego di piccole sequenze peptidiche (15 amminoacidi), opportunamente disegnate, che hanno un potenziale impiego per il targeting di cellule tumorali ed eventualmente per la terapia. Tali peptidi potrebbero trovare impiego, opportunamente funzionalizzati, come sonde per il riconoscimento selettivo dei recettori del VEGF overespressi nei fenomeni di angiogenesi patologica. / [ENGLISH] Angiogenesis is an essential process for the growth of solid tumors; it was shown that the suppression of even only one phase of this process may inhibit new vessels formation, thus affecting tumor growth and metastasis generation.
Aim of this work was to develop small molecules able to modulate activity of molecular systems involved in the angiogenic process. Two systems that are the most important and showed in the field of regulation of angiogenic process have been select: the receptor for matrix protein integrin αVβ3 and the vascular endothelial growth factor VEGF.
About integrin αVβ3, a new chimeric peptide was designed, named RGDechi, that proved a novel and selective inhibitor of this integrin. This molecule may represent the lead compound for the development of novel anticancer drugs and/or new class of diagnostic non-invasive tracers as suitable tools for αVβ3-targeted therapy and imaging.
About VEGF, peptidic antagonists of this natural protein were developed using small peptide sequences (15 amino acids), opportunely designed, that have a potential application in tumor cells targeting and therapy. These peptides, opportunely functionalized, may be used as biospecific probes for the selective recognition of VEGF receptors overexpressed in pathological angiogenesis.

description: The localization of waves in non-periodic media is a universal phenomenon, occurring in a variety of different quantum and classical systems, including condensed-matter, Bose-Einstein condensates in optical lattices, quantum chaotic systems, sound waves and light. A localization phase transition is expected to occur in three dimensional disordered systems as the strength of disorder crosses a critical value. Recently, a crossover from an extended to a localized phase has been observed in low-dimensional photonic lattices and Bose-Einstein condensates. Other experiments studied the critical behaviour near the transition in three dimensions via transmission measurements. However, no direct observation of a localization transition for light has been reported. In 1979 Aubry and Andre predicted that for a certain class of quasi-periodic potentials, a localization phase transition can occur already in one-dimension. This strongly correlated potential is markedly different from the disordered case were the potential is uncorrelated. Here we report an experiment that realizes the Aubry-Andre model in quasi-periodic photonic lattices. We observe the signature of a localization phase transition by directly measuring the expansion rates of initially narrow wave packets propagating in the lattice. Below the transition point, all the modes of the system are extended and therefore an initially narrow wave-packet eventually spreads across the entire lattice. Above the critical point, all modes are localized and expansion is suppressed. In addition, we study the effect of weak nonlinear interactions on light propagation below and above the transition.

description: The paper introduces a novel, hierarchical preconditioner based on nested dissection and hierarchical matrix compression. The preconditioner is intended for continuous and discontinuous Galerkin formulations of elliptic problems. We exploit the property that Schur complements arising in such problems can be well approximated by hierarchical matrices. An approximate factorization can be computed matrix-free and in a (quasi-)linear number of operations. The nested dissection is specifically designed to aid the factorization process using hierarchical matrices. We demonstrate the viability of the preconditioner on a range of 2D problems, including the Helmholtz equation and the elastic wave equation. Throughout all tests, including wave phenomena with high wavenumbers, the generalized minimal residual method (GMRES) with the proposed preconditioner converges in a very low number of iterations. We demonstrate that this is due to the hierarchical nature of our approach which makes the high wavenumber limit manageable.

description: We introduce a notion of continuous crystal analogous, for general Coxeter groups, to the combinatorial crystals introduced by Kashiwara in representation theory of Lie algebras. We use a generalization of the Littelmann path model to show the existence of the crystals, and study an associated Duistermaat-Heckman measure, which we interpret in terms of Brownian motion. We also show that the Littelmann path operators can be derived from simple considerations on Sturm-Liouville equations.

description: We present an initial analysis of AKARI 18um-selected galaxies using all 9 photometric bands at 2-24um available in the InfraRed Camera (IRC), in order to demonstrate new capabilities of AKARI cosmological surveys. We detected 72 sources at 18um in an area of 50.2 arcmin^2 in the AKARI/IRC monitor field towards the North Ecliptic Pole (NEP). From this sample, 25 galaxies with probable redshifts z>~ 0.5 are selected with a single colour cut (N2-N3>0.1) for a detailed SED analysis with ground-based BVRi'z'JK data. Using an SED radiative transfer model of starbursts covering the wavelength range UV -- submm, we derive photometric redshifts from the optical-MIR SEDs of 18um-selected galaxies. From the best-fit SED models, we show that the IRC all-band photometry is capable of tracing the steep rise in flux at the blue side of the PAH 6.2um emission feature. This indicates that the IRC all-band photometry is useful to constrain the redshift of infrared galaxies, specifically for dusty galaxies with a less prominent 4000A break. Also, we find that the flux dip between the PAH 7.7 and 11.2um emission feature is recognizable in the observed SEDs of galaxies at z~1. By using such a colour anomaly due to the PAH and silicate absorption features, unique samples of ULIRGs at z~1, `silicate-break' galaxies, can be constructed from large cosmological surveys of AKARI towards the NEP, i.e. the NEP-Deep and NEP-Wide survey. This pilot study suggests the possibility of detecting many interesting galaxy properties in the NEP-Deep and Wide surveys, such as a systematic difference in SEDs between high- and low-z ULIRGs, and a large variation of the PAH inter-band strength ratio in galaxies at high redshifts.

Characterization of the recombination enhancer, rec-1, in Caenorhabditis elegans
Creators: name: Rattray, Bruce
Publisher: name: University of British Columbia
Year: 2010

description: The hyper-rec mutation rec-1, in Caenorhabditis elegans, has previously been shown to increase intergenic recombination frequency by a factor of three (Rose and Baillie, 1979a). The further characterization of the effect of rec-1 on recombination and other meiotic processes has been the focus of this thesis. The effect of rec-1 on intragenic recombination, gene conversion, fecundity, competitive ability, nondisjunction and mutation rate were examined. The rec-1 mutation produced a two to three-fold increase in intragenic recombination and gene conversion. Pleiotropic effects are typical of recombination mutants, however, only the rate of X-chromosome nondisjunction and/or chromosome loss was affected by rec-1, exhibiting a two-fold increase relative to the N2 (wild-type) strain. In addition to the above, a strain was constructed to determine if the rec-1 mutation was an amber, nonsense mutation (ie. a premature stop codon, preventing translation). The results showed that the expression of the Rec-1 phenotype was not affected by a tRNA amber suppressor (ie. sup-7). This indicated that rec-1 is not an amber mutation. The affect of rec-1 as a recombination enhancer on the mobility of the transposable element, Tc1, was also examined. Electrophoretic banding patterns produced by DNA restriction fragments probed with Tc1 were compared for the N2 and Rec-1 strains. An altered banding pattern was found, suggesting that rec-1 activates Tc1 mobility. However, predicted differences between two Rec-1 DNA samples (one prepared two years after the other) were not found. Several alternative explanations are considered. High recombination mutations reported in the literature are reviewed and several hypotheses consistent with the above results are considered as possible explanations of the rec-1 enhancer.

description: Fine time-resolved analysis of matter - i.e. spectroscopy and photon scattering - in the linear response regime requires a fs-scale pulsed, high repetition rate, fully coherent X-ray source. A seeded Free-Electron Laser (FEL) driven by a Super-Conducting Linac, generating $10^{8}$-$10^{10}$ coherent photons at 2-5 keV with abou 0.5 MHz of repetition rate, can address this need. The seeding scheme proposed is the Echo-Enabled Harmonic Generation, alimented by a FEL Oscillator working at 13.6 nm with a cavity based on Mo-Si mirrors. The whole chain of the X-ray generation is here described by means of start-to-end simulations. Comparisons with the Self Amplified Spontaneus Emission and a fresh-bunch harmonic cascade performed with similar electron beams show the validity of this scheme.

description: Optical Character Recognition (OCR) systems have been widely used in various applications for extracting semantic information from images. To give the user more control over their privacy, an on-device solution is needed. The current state-of-the-art models are too heavy and complex to be deployed on-device. We develop an efficient lightweight scene text recognition (STR) system, which has only 0.88M parameters and performs real-time text recognition. Attention modules tend to boost the accuracy of STR networks but are generally slow and not optimized for device inference. So, we propose the use of convolution attention modules to the text recognition networks, which aims to provide channel and spatial attention information to the LSTM module by adding very minimal computational cost. It boosts our word accuracy on ICDAR 13 dataset by almost 2\%. We also introduce a novel orientation classifier module, to support the simultaneous recognition of both horizontal and vertical text. The proposed model surpasses on-device metrics of inference time and memory footprint and achieves comparable accuracy when compared to the leading commercial and other open-source OCR engines. We deploy the system on-device with an inference speed of 2.44 ms per word on the Exynos 990 chipset device and achieve an accuracy of 88.4\% on ICDAR-13 dataset.

description: Die vorliegende Arbeit handelt von der Optimierung der photokatalytischen Aktivität von quaternären Metalloxiden mit Defekt-Pyrochlorstruktur. Die kubische Kristallstruktur bietet vielfältige Möglichkeiten, um nicht nur die optischen Eigenschaften wie Licht-Absorption und Bandlücke, sondern auch die elementare Zusammensetzung zu variieren, ohne dabei die für Wasserspaltung geeigneten Bandpositionen zu beeinträchtigen. Kaliumtantalwolframat KTaWO6 Nanopartikel mit einstellbaren Kristallit-Größen wurden mittels Hydrothermalmethode synthetisiert. Es hat sich gezeigt, dass Wassermoleküle in die Kristallstruktur eingebaut werden können, was den Ionen-Austausch von K+ gegen Sn2+ erheblich verbessert. Die Kombination aus den 5s2 Zuständen von Sn2+ und der Einbau von Wasser reduziert die Bandlücke der Ionen-ausgetauschten Materialien um bis zu 1,4 eV. Allerdings sind diese Materialien anfällig für Selbst-Oxidation während Bestrahlung, gefolgt vom Auswaschen von Sn aus den Proben. Die mögliche Bandbreite an elementaren Zusammensetzungen von CsMxW2-xO6 wurde untersucht, wobei das Mn+-Kation entweder M5+, M4+, M3+ oder sogar M2+ sein kann. Für Mn+-Kationen mit d0- oder d10-Elektronenkonfiguration ist der Einfluss auf Bandstruktur vernachlässigbar und die photokatalytische Aktivität ist annähernd vergleichbar. Für Mn+-Kationen mit nur teilweise gefüllten d-Zuständen ändern sich die optischen Eigenschaften drastisch, allerdings verringert sich vermutlich die Lebenszeit der photoangeregten Ladungsträger. Die unterschiedlichen A Kationen in Alkalimetall-Niob-Telluroxiden ANbTeO6 mit A = K+, Rb+ und Cs+ resultieren in unterschiedlichen Defekt-Konzentrationen und einer verzerrten Kristallstruktur. Die Defekte verursachen die Absorption sichtbaren Lichtes unterschiedlichen Ausmaßes, jedoch ändern sich weder die Bandlücke von 3.4 eV noch die Ladungsträgerkonzentration. Die Bestrahlung mit UV-Licht resultiert sowohl in einer Reduktion von Oberflächen-Spezies zu metallischem Tellur und niedervalenten Niob-Verbindungen als auch in geänderten Defektkonzentrationen.

description: We investigate the coupled dynamics of quantized vortices and normal fluid in superfluid $^4$He at finite temperatures using a numerical approach based on the vortex filament model (VFM) and lattice Boltzmann method (LBM). The LBM allows us to simulate a fluid flow with only local operations, i .e., rather than solving the Navier--Stokes (NS) equations directly; a fluid flow is considered a convection of mesoscopic particles between sites on a lattice grid. Although the two-fluid nature of He II makes its flow complex, the particle-like treatment of the normal fluid in the LBM significantly reduces the complexity. We confirm, by comparing to results obtained with direct NS simulations, that the proposed numerical approach reproduces characteristic flow structures. We also demonstrate that the proposed computational approach is suitable for a thermal counterflow simulation with a solid boundary to elucidate a thermal boundary layer near a heater in a closed channel.

description: We have estimated the sensitivity to the anomalous couplings of the $γγγZ$ vertex in the $γγ\rightarrowγZ$ scattering of the Compton backscattered photons at the CLIC. Both polarized and unpolarized collisions at the $e^+e^-$ energies 1500 GeV and 3000 GeV are addressed, and anomalous contributions to helicity amplitudes are derived. The differential and total cross sections are calculated. We have obtained 95\% C.L. exclusion limits on the anomalous quartic gauge couplings (QGCs). They are compared with corresponding bounds derived for the $γγγZ$ couplings via $γZ$ production at the LHC. The constraints on the anomalous QGCs are one to two orders of magnitude more stringent that at the HL-LHC. The partial-wave unitarity constraints on the anomalous couplings are examined. It is shown that the unitarity is not violated in the region of the anomalous QGCs studied in the paper.

description: We continue the analysis of models of spontaneous wave function collapse with stochastic dynamics driven by non-white Gaussian noise. We specialize to a model in which a classical "noise" field, with specified autocorrelator, is coupled to a local nonrelativistic particle density. We derive general results in this model for the rates of density matrix diagonalization and of state vector reduction, and show that (in the absence of decoherence) both processes are governed by essentially the same rate parameters. As an alternative route to our reduction results, we also derive the Fokker-Planck equations that correspond to the initial stochastic Schrödinger equation. For specific models of the noise autocorrelator, including ones motivated by the structure of thermal Green's functions, we discuss the qualitative and qantitative dependence on model parameters, with particular emphasis on possible cosmological sources of the noise field.

description: The perpendicular shape anisotropy-spin transfer torque-magnetic random access memories (PSASTT-MRAMs) takes advantage of the nanopillar free-layer geometry for securing a good thermal stability factor from the shape anisotropy of the nanomagnet. Such a concept is particularly well-suited for small junctions down to a few nanometers. At such a volume size, the nanopillar can be effectively modeled as a Stoner-Wohlfarth (SW) particle, and the shape anisotropy scales with the spontaneous magnetization by ~ Ms^2. For almost all ferromagnets, Ms is a strong function of temperature, therefore, the temperature-dependent shape anisotropy is an important factor to be considered in any modeling of the temperature-dependent performance of PSA-STT-MRAMs. In this work, we summarize and discuss various possible temperature-dependent contributions to the thermal stability factor and coercivity of the PSA-STT-MRAMs by modeling and comparing different temperature scaling and parameters. We reveal nontrivial corrections to the thermal stability factor by considering both temperature-dependent shape and interfacial anisotropies. The coercivity, blocking temperature, and electrical switching characteristics that resulted from incorporating such a temperature dependence are also discussed, in conjugation with the nanomagnet dimension and coherence volume.

description: Exciton effects are studied in single-wall boron-nitride (BN) nanotubes. Linear absorption spectra are calculated with changing the chiral index of the zigzag nanotubes. We consider the extended Hubbard model with atomic energies at the boron and nitrogen sites. Exciton effects are calculated using the configuration interaction technique. The Coulomb interaction dependence of the band gap, the lowest exciton energy, and the binding energy of the exciton are discussed. The optical gap of the (5,0) nanotube is about 6 eV at the onsite interaction U=2t with the hopping integral t=1.2 eV. The binding energy of the exciton is 0.50 eV for these parameters. This energy agrees well with that of other theoretical investigations. We find that the energy gap and the binding energy are almost independent of the geometries of the nanotubes. This novel property is in contrast with that of the carbon nanotubes which show metallic and semiconducting properties depending on the chiral index.

Specifically we apply the theory of Lie symmetries to determine all the infinitesimal generators of the one-parameter point transformations which leave the system invariant. We use these transformations to define invariant similarity transformations which are used to simplify the differential equations and find the exact form of the spacetime. We show that the constraint equations admit an infinite number of symmetries which can be used to construct an infinite number of similarity transformations.

description: If the two lightest neutralinos of the Minimal Supersymmetric Standard Model have a mass splitting less than the Z boson mass, interference effects in the three-body decay chi_2^0 --> chi_1^0 f f can be important. We formulate an observable that contains information on the nature of the interference: the ratio BR(chi_2^0 --> chi_1^0 b b) / BR(chi_2^0 --> chi_1^0 l+ l-). This will give a constraint on the supersymmetry breaking parameters that is complementary to many techniques already existing in the literature. We present some ideas on how to perform a simple counting experiment to determine this ratio.

description: Optical depth variations in the Galactic neutral interstellar medium (ISM) with spatial scales from hundreds to thousands of astronomical units have been observed through HI absorption against pulsars and continuum sources, while extremely small structures with spatial scales of tens of astronomical units remain largely unexplored. The nature and formation of such tiny-scale atomic structures (TSAS) need to be better understood. We report a tentative detection of TSAS with a signal-to-noise ratio of 3.2 toward PSR B1557$-$50 in the second epoch of two Parkes sessions just 0.36 yr apart, which are the closest-spaced spectral observations toward this pulsar. One absorption component showing marginal variations has been identified. Based on the pulsar's proper motion of 14 mas $\rm yr^{-1}$ and the component's kinematic distance of 3.3 kpc, the corresponding characteristic spatial scale is 17 au, which is among the smallest sizes of known TSAS. Assuming a similar line-of-sight (LOS) depth, the tentative TSAS cloud detected here is overdense and overpressured relative to the cold neutral medium (CNM), and can radiatively cool fast enough to be in thermal equilibrium with the ambient environment. We find that turbulence is not sufficient to confine the overpressured TSAS. We explore the LOS elongation that would be required for the tentative TSAS to be at the canonical CNM pressure, and find that it is $\sim5000$ -- much larger than filaments observed in the ISM. We see some evidence of line width and temperature variations in the CNM components observed at the two epochs, as predicted by models of TSAS-like cloud formation colliding warm neutral medium flows.

description: In the contact interaction model, the quark propagator has only one solution, chiral symmetry breaking solution, at vanish temperature and density. Inspire by Y. Jiang and Z.-F. Cui, we introduce 2+1 flavors quark condensates feedback on coupling strength, the Wigner solution appears in some region of parameters. It enables us to tackle chiral phase transition as two-phase coexistences. At finite chemical potential, we analyze the chiral phase transition to the conditions of electric charge neutrality and $β$ equilibrium. The four chemical potentials, $μ_u$, $μ_d$, $μ_s$ and $μ_e$, are constrained by three conditions, there is one independent variable that remained, we choose the average quark chemical potential as the free variable. All quark masses and number densities suffer discontinuities at the phase transition point. The strange quarks appear after the phase transition due to the system needs more energy to produce a d-quark than an s-quark. Take the EOS as an input, the TOV equations are solved numerically, we show that the mass-radius relation is sensitive to the EOSs. The maximum mass of strange quark stars is not susceptible to our introduced parameter $Λ_q$.

A planned strategy for developing Burrard Inlet's shore-based sport fisheries
Creators: name: Renyard, Thomas Scott
Publisher: name: University of British Columbia
Year: 2010

description: Sports angling in Pacific Northwest waters has been predominantly for salmon from small recreational boats. This has led to a concentration of management resources on the sport salmon fishery. Eight shore-based sport fisheries in Burrard Inlet, however, do not fit into the management framework in place for the boat salmon fishery and have, therefore, been neglected. In contrast, shore-based sport fisheries have been developed in the U.S. and elsewhere, and have realized social, environmental and economic benefits, for urban communities. This thesis analyses Burrard Inlet shore-based sport fisheries and proposes a strategy for improving them to satisfy possible latent demands. Little was known about Burrard Inlet's shore-based sport fisheries so several methods have been used to characterize these fisheries and the network of management agencies. The methods include a survey of shore anglers, a telephone survey of numerous public agencies, and an informal workshop with professionals interested in Burrard Inlet shore fishery development. The proposed planned strategy outlines the managerial, organizational and promotional concerns in developing Burrard Inlet's shore-based sport fisheries. In general, all of the shore sport fisheries can be managed together with artificial reef/angling pier developments, excepting to some extent the smelt and salmon fisheries. This collective management scheme allows the managing agency to establish commonly fished and habitat reserve areas for the species used in Burrard Inlet's fisheries. This strategy restricts angling in some areas and encourages it in other areas for most of the species. This will ensure some protection of stocks in our intensely fished area and-will simplify the task of enforcing area closures. The relationships between managing agencies and shore anglers have, in the past, been informal. It is proposed that some of the agencies around the inlet form an inter-agency committee to streamline the development process. The inter-agency committee should also improve its relationship with the shore anglers and encourage the anglers to take some of the responsibility of improving the fishery themselves. Since the Burrard Inlet fisheries are not well known in the community, to achieve the development objective, promotion of its value may be needed. It is suggested that the fishery be promoted in two phases. The first phase would be undertaken by the existing informal DFO shore fishery committee to encourage other agencies to form the inter-agency committee. The second phase would be undertaken by the newly formed joint committee to gain the support and investment from the general public, the shore anglers and the private sector.

description: Current Continuous Integration processes face significant intrinsic cybersecurity challenges. The idea is not only to solve and test formal or regulatory security requirements of source code but also to adhere to the same principles to the CI pipeline itself. This paper presents an overview of current security issues in CI workflow. It designs, develops, and deploys a new tool for the secure deployment of a container-based CI pipeline flow without slowing down release cycles. The tool, called \SD for its Docker-based approach, is publicly available in GitHub. It implements a transparent application firewall based on a configuration mechanism avoiding issues in the CI workflow associated with intended or unintended container configurations. Integrated with other DevOps Engineers tools, it provides feedback from only those scenarios that match specific patterns, addressing future container security issues.

An Isochrone Database and a Rapid Model for Stellar Population Synthesis

Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We first presented an isochrone database that can be widely used for stellar population synthesis studies and colour-magnitude diagram (CMD) fitting. The database consists of the isochrones of both single star and binary star simple stellar populations (ss-SSPs and bs-SSPs). The ranges for the age and metallicity of populations are 0--15 Gyr and 0.0001--0.03, respectively. All data are available for populations with Salpeter IMF and Chabrier IMF. Then based on the isochrone database, we built a rapid stellar population synthesis (RPS) model and calculated the high-resolution (0.3 AA) integrated spectral energy distributions (SEDs), Lick indices and colour indices for bs-SSPs and ss-SSPs. In particular, we calculated the UBVRIJHKLM colours, ugriz colours and some composite colours that consist of magnitudes on different systems. As an example for applying the isochrone database for CMD fitting, we fitted the CMDs of star clusters M67 and NGC1868 and obtained their distance moduli, colour excesses, stellar metallicities and ages. The results showed that the isochrones of bs-SSPs are closer to those of real star clusters. The isochrone database, colours, Lick indices of populations can be downloaded via http://www.ynao.ac.cn/~bps/zhongmu/download.htm

Matrix kernels for measures on partitions

description: We consider the problem of computation of the correlation functions for the z-measures with the deformation (Jack) parameters 2 or 1/2. Such measures on partitions are originated from the representation theory of the infinite symmetric group, and in many ways are similar to the ensembles of Random Matrix Theory of $β=4$ or $β=1$ symmetry types. For a certain class of such measures we show that correlation functions can be represented as Pfaffians including $2\times 2$ matrix valued kernels, and compute these kernels explicitly. We also give contour integral representations for correlation kernels of closely connected measures on partitions.

description: We establish a direct map between refined topological vertex and sl(N) homological invariants of the of Hopf link, which include Khovanov-Rozansky homology as a special case. This relation provides an exact answer for homological invariants of the of Hopf link, whose components are colored by arbitrary representations of sl(N). At present, the mathematical formulation of such homological invariants is available only for the fundamental representation (the Khovanov-Rozansky theory) and the relation with the refined topological vertex should be useful for categorifying quantum group invariants associated with other representations (R_1, R_2). Our result is a first direct verification of a series of conjectures which identifies link homologies with the Hilbert space of BPS states in the presence of branes, where the physical interpretation of gradings is in terms of charges of the branes ending on Lagrangian branes.

Environmental and genetic influences on the life span of adult Drosophila melanogaster
Creators: name: Richter, Murray Dean
Publisher: name: University of British Columbia
Year: 2010

description: The onset of senescence and the rate at which organisms age are influenced by both extrinsic and intrinsic factors. Extrinsic factors include temperature, humidity and diet. Intrinsic factors arise within an organism as a result of normal metabolism. An example is the production of free radicals, highly reactive compounds that usually arise as byproducts of normal oxidative functions. Another less commonly considered instrinsic factor is the genetic makeup of an organism. Not only do different species have different characteristic life spans, but different strains within a species also have different characteristic life spans. This study examines how environmental and genetic differences affect the adult life span of Drosophila melanogaster. Drosophila was chosen because of its well characterized genetics, the ease with which it can be cultured and its life span measured, and the ability to control environmental conditions, particularly temperature. The study used three different approaches. The first approach looked at the influence of preimaginal development on adult longevity. The duration of development of melanogaster was altered using developmental temperature shifts. Both a wild-type strain and a mutant strain that displays a longer developmental period at 29°C than at 22°C were examined. No correlation was found between developmental duration and adult life span in either strain. The second approach examined the differences in adult longevity that existed between a highly inbred laboratory strain and four strains recently isolated from the wild. This was done to assess the suitability of highly inbred strains for studying aging. The laboratory strain showed much less variation in life span than did any of the recently isolated strains. The third approach looked at the possible roles of DNA damage accumulation and DNA repair in controlling life span in Drosophila. Mutagen-sensitive (mus) mutants representing strains that are potentially defective in DNA repair were examined to see if their life spans were altered relative to control strains. Little difference was found between mus strains and the controls. Where differences did exist, it was not clear that they were a direct result of defective repair in the adult. The results of each approach are discussed with respect to current knowledge of the processes controlling aging and senescence in Drosophila and other organisms.
