description: We study a 5-dimensional $f({\cal R})$ brane gravity within the framework of scalar-tensor type theories. We show that such a model predicts, for a certain choice of $f({\cal R})$ and a spatially flat universe, an exponential potential, leading to an accelerated expanding universe driven solely by the curvature of the bulk space. This result is consistent with the observational data in the cosmological scale.

description: We study parameter estimation with post-Newtonian (PN) gravitational waveforms for the quasi-circular, adiabatic inspiral of spinning binary compact objects. The performance of amplitude-corrected waveforms is compared with that of the more commonly used restricted waveforms, in Advanced LIGO and EGO. With restricted waveforms, the properties of the source can only be extracted from the phasing. For amplitude-corrected waveforms, the spectrum encodes a wealth of additional information, which leads to dramatic improvements in parameter estimation. At distances of $\sim 100$ Mpc, the full PN waveforms allow for high-accuracy parameter extraction for total mass up to several hundred solar masses, while with the restricted ones the errors are steep functions of mass, and accurate parameter estimation is only possible for relatively light stellar mass binaries. At the low-mass end, the inclusion of amplitude corrections reduces the error on the time of coalescence by an order of magnitude in Advanced LIGO and a factor of 5 in EGO compared to the restricted waveforms; at higher masses these differences are much larger. The individual component masses, which are very poorly determined with restricted waveforms, become measurable with high accuracy if amplitude-corrected waveforms are used, with errors as low as a few percent in Advanced LIGO and a few tenths of a percent in EGO. The usual spin-orbit parameter $β$ is also poorly determined with restricted waveforms (except for low-mass systems in EGO), but the full waveforms give errors that are small compared to the largest possible value consistent with the Kerr bound. This suggests a way of finding out if one or both of the component objects violate this bound. We also briefly discuss the effect of amplitude corrections on parameter estimation in Initial LIGO.

The effect of fish predation on benthic community structure in streams
Creators: name: Rosenfeld, Jordan Stuart
Publisher: name: University of British Columbia
Year: 2009

description: The conditions under which fish have a large impact on benthic invertebrate community structure in streams are poorly defined. To better understand the mechanisms by which fish affect lotic invertebrate community structure, a series of experiments were performed in a fishless and fish-bearing stream in the University of British Columbia Malcolm Knapp Research Forest in the Coast Mountains of British Columbia. The first experiment examined the effect of predation by prickly sculpin (Cottus asper) and coho parr (Onchorhynchus kisutch) on invertebrates associated with tile and gravel substrate placed in enclosures installed in pools and riffles in fishless Mayfly Creek.. Effects of fish were most pronounced on tile substrate and in riffle habitat, and least pronounced on gravel substrate in pool habitat. Fish predation resulted in decreased density of larger-bodied (>6mm) herbivores (primarily the mayflies Ameletus and Baetis) and increased abundance of smaller (< 3mm) herbivorous invertebrates (primarily Orthocladiinae chironomids and nemourid stoneflies) and algae. The effects of fish predation in riffles in fish-bearing Jacobs Creek were similar to those observed in Mayfly Creek, except that there was no increase in algal biomass in the presence of fish. The indirect increase in algal biomass and density of small herbivores observed under fish predation was reproduced in experimental stream channels by excluding large invertebrate herbivores (tailed frog tadpoles (Ascaphus) and Ameletus), confirming that direct effects of fish on large-bodied grazers released algae and smaller herbivores from competitively dominant grazers. Manipulation of coho densities in upper enclosure sections in a fourth experiment indicated that upstream predation could have a small but measurable indirect effect on algal biomass in downstream patches. The abundance of detritivores in Mayfly and Jacobs Creek appear to be largely controlled by bottom-up forces (resource limitation), while herbivores are more strongly influenced by top-down effects (fish predation). A model for effects of fish predation on invertebrate community structure is proposed which predicts stronger predation effects in algal-based food chains than detrital-based food chains, both of which occur at a hierarchy of spatial scales in streams.

description: The focus of the study is to develop a 3D engine assembly simulation learning module to address the lack of equipment in one senior high school in the Philippines. The study used mixed-method to determine the considerations needed in developing an application for educational use particularly among laboratory/practical subjects like engine assembly. The study used ISO 25010 quality standards in evaluating the application(n=153 students and 3 ICT experts).Results showed that the application is moderately acceptable(overall mean = 3.52) under ISO 25010 quality standards. The study created an engine simulation learning assembly in which teachers can use to augment their lesson. The study also highlights the applicability of using 3D-related technologies for practical and laboratory subjects particularly highly technical-related subjects. Future studies may develop a similar application in the same context using mobile and other emerging technology(i.e., Virtual Reality, Augmented Reality) as well as making the content more customizable. Effectivity of the system in an actual setting is also worth pursuing. The study highlighted the potential use of 3D technology in a classroom setting.

description: After the successful landing of the Mars Science Laboratory rover, both NASA and ESA initiated a selection process for potential landing sites for the Mars2020 and ExoMars missions, respectively. Two ellipses located in the Mawrth Vallis region were proposed and evaluated during a series of meetings (3 for Mars2020 mission and 5 for ExoMars). We describe here the regional context of the two proposed ellipses as well as the framework of the objectives of these two missions. Key science targets of the ellipses and their astrobiological interests are reported. This work confirms the proposed ellipses contain multiple past Martian wet environments of subaerial, subsurface and/or subaqueous character, in which to probe the past climate of Mars, build a broad picture of possible past habitable environments, evaluate their exobiological potentials and search for biosignatures in well-preserved rocks. A mission scenario covering several key investigations during the nominal mission of each rover is also presented, as well as descriptions of how the site fulfills the science requirements and expectations of in situ martian exploration. These serve as a basis for potential future exploration of the Mawrth Vallis region with new missions and describe opportunities for human exploration of Mars in terms of resources and science discoveries.

description: We investigate the potential of the next generation long-baseline neutrino experiments DUNE and T2HK as well as the upcoming reactor experiment JUNO to constrain Non-Standard Interaction (NSI) parameters. JUNO is going to provide the most precise measurements of solar neutrino oscillation parameters as well as determining the neutrino mass ordering. We study how the results of JUNO combined with those of long-baseline neutrino experiments such as DUNE and T2HK can help to determine oscillation parameters and to constrain NSI parameters. We present excluded regions in NSI parameter space, $ε_{αβ}$ assuming Standard Model (SM) as the null hypothesis. We further explore the correlations between the NSI parameters and CP-violation phase.

Acquisizione dati o “Data Acquisition” (DAQ nel seguito) è l’insieme degli strumenti che permettono di acquisire delle informazioni in forma digitale da sensori o apparati complessi. La selezione dei dati utili e la contestuale eliminazione di quelli non interessanti è generalmente effettuata da un sistema chiamato Trigger. DAQ e Trigger non sono attività semplici da realizzare e non è facile ricavare dei modelli descrittivi generali validi per ogni contesto sperimentale, tuttavia molti aspetti sono ben conosciuti e fanno riferimento a conoscenze largamente applicate anche in altri campi. Un altro elemento di difficoltà nell’approccio al DAQ è che non ci sono testi sistematici ed esaustivi sull’argomento. Questo testo di appunti del Corso di Acquisizione Dati e Controllo di Esperimenti ha il compito non facile di mettere insieme quanto necessario per una comprensione delle problematiche principali senza la pretesa di essere esaustivo.
Heterogeneous bounds of confidence: Meet, Discuss and Find Consensus!

Year: 2008
Subjects: subject: Physics and Society (physics.soc-ph)
subject: FOS: Physical sciences

description: Models of continuous opinion dynamics under bounded confidence show a sharp transition between a consensus and a polarization phase at a critical global bound of confidence. In this paper, heterogeneous bounds of confidence are studied. The surprising result is that a society of agents with two different bounds of confidence (open-minded and closed-minded agents) can find consensus even when both bounds of confidence are significantly below the critical bound of confidence of a homogeneous society. The phenomenon is shown by examples of agent-based simulation and by numerical computation of the time evolution of the agents density. The result holds for the bounded confidence model of Deffuant, Weisbuch and others (Weisbuch, G. et al; Meet, discuss, and segregate!, Complexity, 2002, 7, 55--63), as well as for the model of Hegselmann and Krause (Hegselmann, R., Krause, U.; Opinion Dynamics and Bounded Confidence, Models, Analysis and Simulation, Journal of Artificial Societies and Social Simulation, 2002, 5, 2). Thus, given an average level of confidence, diversity of bounds of confidence enhances the chances for consensus. The drawback of this enhancement is that opinion dynamics becomes suspect to severe drifts of clusters, where open-minded agents can pull closed-minded agents towards another cluster of closed-minded agents. A final consensus might thus not lie in the center of the opinion interval as it happens for uniform initial opinion distributions under homogeneous bounds of confidence. It can be located at extremal locations. This is demonstrated by example. This also show that the extension to heterogeneous bounds of confidence enriches the complexity of the dynamics tremendously.

On the energy of the protons producing the very high-energy astrophysical neutrinos

description: We study the distribution of the energy of the protons that can produce an astrophysical neutrino with a given observed energy, in the TeV--PeV range, both through $pp$ or $pγ$ interactions. Due to the increasing multiplicity of the pion production at high center of mass energies, the resulting average proton energies can be much larger than the often used approximate value $E_p\simeq 20E_ν$. Also the threshold of the $pγ$ process can lead to a pronounced increase in the values of $\langle E_p\rangle /E_ν$ for decreasing neutrino energies. The results depend sensitively on the assumed proton spectrum, since steeper spectra give less weight to the lower energy neutrino tail resulting from the decays of the abundant low-energy pions. In the $pγ$ scenarios they also depend sensitively on the spectrum of the target photons. The results are in particular relevant to relate possible characteristics of the neutrino spectrum to those of the corresponding cosmic rays that generated them. We also discuss the associated production of gamma rays at the sources.

description: The remarkable temporal properties of ultra-short pulsed lasers in combination with novel beam shaping concepts enable the development of completely new material processing strategies. We demonstrate the benefit of employing focus distributions being tailored in all three spatial dimensions. As example advanced Bessel-like beam profiles, 3D-beam splitting concepts and flat-top focus distributions are used to achieve high-quality and efficient results for cutting, welding and drilling applications. Spatial and temporal in situ diagnostics is employed to analyze light-matter interaction and, in combination with flexible digital-holographic beam shaping techniques, to find the optimal beam shape for the respective laser application.

description: We present semi-analytic models of galactic outflows, constrained by available observations on high redshift star formation and reionization. Galactic outflows are modeled in a manner akin to models of stellar wind blown bubbles. Large scale outflows can generically escape from low mass halos (M<10^9 M_sun) for a wide range of model parameters but not from high mass halos (M> 10^{11} M_sun). The gas phase metallicity of the outflow and within the galaxy are computed. Ionization states of different metal species are calculated and used to examine the detectability of metal lines from the outflows. The global influence of galactic outflows is also investigated. Models with only atomic cooled halos significantly fill the IGM at z~3 with metals (with -2.5>[Z/Z_sun]>-3.7), the actual extent depending on the efficiency of winds, the IMF, the fractional mass that goes through star formation and the reionization history of the universe. In these models, a large fraction of outflows at z~3 are supersonic, hot (T> 10^5 K) and have low density, making metal lines difficult to detect. They may also result in significant perturbations in the IGM gas on scales probed by the Lyman-alpha forest. On the contrary, models including molecular cooled halos with a normal mode of star formation can potentially volume fill the universe at z> 8 without drastic dynamic effects on the IGM, thereby setting up a possible metallicity floor (-4.0

description: To study subregions of a turbulence velocity field, a long record of velocity data of grid turbulence is divided into smaller segments. For each segment, we calculate statistics such as the mean rate of energy dissipation and the mean energy at each scale. Their values significantly fluctuate, in lognormal distributions at least as a good approximation. Each segment is not under equilibrium between the mean rate of energy dissipation and the mean rate of energy transfer that determines the mean energy. These two rates still correlate among segments when their length exceeds the correlation length. Also between the mean rate of energy dissipation and the mean total energy, there is a correlation characterized by the Reynolds number for the whole record, implying that the large-scale flow affects each of the segments.

description: We explore the importance of magnetic-field-oriented thermal conduction in the interaction of supernova remnant (SNR) shocks with radiative gas clouds and in determining the mass and energy exchange between the clouds and the hot surrounding medium. We perform 2.5D MHD simulations of a shock impacting on an isolated gas cloud, including anisotropic thermal conduction and radiative cooling; we consider the representative case of a Mach 50 shock impacting on a cloud ten-fold denser than the ambient medium. We consider different configurations of the ambient magnetic field and compare MHD models with or without the thermal conduction. The efficiency of the thermal conduction in the presence of magnetic field is, in general, reduced with respect to the unmagnetized case. The reduction factor strongly depends on the initial magnetic field orientation, and it is minimum when the magnetic field is initially aligned with the direction of shock propagation. The thermal conduction contributes to suppress hydrodynamic instabilities, reducing the mass mixing of the cloud and preserving the cloud from complete fragmentation. Depending on the magnetic field orientation, the heat conduction may determine a significant energy exchange between the cloud and the hot surrounding medium which, while remaining always at levels less than those in the unmagnetized case, leads to a progressive heating and evaporation of the cloud. This additional heating may contrast the radiative cooling of some parts of the cloud, preventing the onset of thermal instabilities.

description: Employing the notion of operator log-convexity, we study joint concavity$/$ convexity of multivariable operator functions: $(A,B)\mapsto F(A,B)=h\left[ Φ(f(A))\ σ Ψ(g(B))\right]$, where $Φ$ and $Ψ$ are positive linear maps and $σ$ is an operator mean. As applications, we prove jointly concavity$/$convexity of matrix trace functions $\Tr\left\{ F(A,B)\right\}$. Moreover, considering positive multi-linear mappings in $F(A,B)$, our study of the joint concavity$/$ convexity of $(A_1,\cdots,A_k)\mapsto h\left[ Φ(f(A_1),\cdots,f(A_k))\right]$ provides some generalizations and complement to results of Ando and Lieb concerning the concavity$/$ convexity of maps involving tensor product. In addition, we present Minkowski type operator inequalities for a unial positive linear map, which is an operator version of Minkowski type matrix trace inequalities under a more general setting than Carlen and Lieb, Bekjan, and Ando and Hiai.

description: In the framework of the ESA Athena mission, the X-ray Integral Field Unit (X-IFU) instrument to be on board the X-ray Athena Observatory is a cryogenic micro-calorimeter array of Transition Edge Sensor (TES) detectors aimed at providing spatially resolved high-resolution spectroscopy. As a part of the on-board Event Processor (EP), the reconstruction software will provide the energy, spatial location and arrival time of the incoming X-ray photons hitting the detector and inducing current pulses on it. Being the standard optimal filtering technique the chosen baseline reconstruction algorithm, different modifications have been analyzed to process pulses shorter than those considered of high resolution (those where the full length is not available due to a close pulse after them) in order to select the best option based on energy resolution and computing performance results. It can be concluded that the best approach to optimize the energy resolution for short filters is the 0-padding filtering technique, benefiting also from a reduction in the computational resources. However, its high sensitivity to offset fluctuations currently prevents its use as the baseline treatment for the X-IFU application for lack of consolidated information on the actual stability it will get in flight.

description: 8-Gsps 1-bit Analog-to-Digital Converters (ADCs) were newly developed toward the realization of the wideband observation. The development of the wideband ADCs is one of the most essential developments for the radio interferometer. To evaluate its performance in interferometric observations, the time (phase) stability and frequency response were measured with a noise source and a signal generator. The results of these measurements show that the developed ADCs can achieve the jitter time less than 0.05 psec at the time interval of 1 sec, the passband frequency response with the slope less than 0.73 dB/GHz and the ripple less than 1.8 dB, and the aperture time less than 20 psec. The details of the developed ADC design, the measurement methods, and the results of these measurements are presented in this paper.

description: O oídio causado pelo fungo Pseudoidium anacardii é atualmente a doença mais importante do cajueiro. Os sintomas ocorrem em brotações, no pedúnculo e na castanha. Objetivou-se avaliar o efeito dos diferentes níveis de severidade do oídio na germinação de castanhas-sementes e no desenvolvimento das plântulas dos clones de cajueiro-anão ‘CCP 06’ e ‘BRS 189’. As castanhas-sementes foram separadas em cinco níveis de severidade da doença como: nível “0” - ausência total de doença; nível “1” – castanha com severidade até 10%; nível “2” - entre 11% a 25%; nível “3” - 26% a 50%; nível “4” - 51% a 75% e nível “5” - acima de 75% de sintomas. Avaliaram-se as características morfométricas das castanhas-sementes e das amêndoas, sua germinação e o desenvolvimento das plântulas até 65 dias após a semeadura (época de enxertia). Os maiores níveis de severidade de oídio influenciaram negativamente a massa, o comprimento e a largura das castanhas-sementes, com consequente aumento na espessura. Já as amêndoas, apenas àquelas do ‘CCP 06’ foram afetadas pela doença, apresentando redução na massa, comprimento e largura quando nos maiores níveis de severidade. A germinação e as características biométricas das plantas dos dois clones não foram prejudicadas pelo oídio nas castanhas-sementes, mesmo em níveis elevados de severidade.

On multilinearity and skew-symmetry of certain symbols in motivic cohomology of fields

Subjects: subject: K-Theory and Homology (math.KT)

description: The purpose of the present article is to show the multilinearity for symbols in Goodwillie-Lichtenbaum complex in two cases. The first case shown is where the degree is equal to the weight. In this case, the motivic cohomology groups of a field are isomorphic to the Milnor's K-groups as shown by Nesterenko-Suslin, Totaro and Suslin-Voevodsky for various motivic complexes, but we give an explicit isomorphism for Goodwillie-Lichtenbaum complex in a form which visibly carries multilinearity of Milnor's symbols to our multilinearity of motivic symbols. Next, we establish multilinearity and skew-symmetry for irreducible Goodwillie-Lichtenbaum symbols in H^{l-1} (Spec k, Z(l)). These properties have been expected to hold from the author's construction of a bilinear form of dilogarithm in case k is a subfield of the field of complex numbers and l=2. Next, we establish multilinearity and skew-symmetry for Goodwillie-Lichtenbaum symbols in H^{l-1} (Spec k, Z(l)). These properties have been expected to hold from the author's construction of a bilinear form of dilogarithm in case k is a subfield of the field of complex numbers and l=2. The multilinearity of symbols may be viewed as a generalization of the well-known formula det(AB) = det(A) det(B) for tuples of commuting matrices.
description: We acknowledge that mutilinearity does not hold for arbitrary symbols in H^{l-1} (Spec k, Z(l)) as claimed in the 1st version and this mistake has been corrected in the 2nd version

A madeira utilizada no experimento foi submetida à termorretificação com duas temperaturas (180 e 200°C) e dois períodos de permanência em estufa (120 e 240 min.). Após os tratamentos térmicos, as amostras de madeira foram submetidas ao ensaio de biodegradação, sendo mantidas em ambiente controlado, com presença do cupim Nasutitermes corniger. (Dictyoptera: Termitidae), durante 45 dias. Os resultados foram submetidos a análise de variância e as médias comparadas pelo teste de Tukey a 5% de significância. Os diferentes tratamentos térmicos alteraram as características avaliadas para a madeira de Qualea paraensis. Três dos quatro tratamentos térmicos avaliados aumentaram a massa específica da madeira. Contudo, também foi verificado um aumento da suscetibilidade da madeira ao ataque de cupins de madeira úmida.

We also discuss the cosmic coincidence problem in the context of holographic dark energy. We find that the coincidence problem can not be completely solved by adding an interacting term. Inflation may provide a better solution of the coincidence problem.

description: In perturbative quantum field theory the maintenance of classical symmetries is quite often investigated by means of algebraic renormalization, which is based on the Quantum Action Principle. We formulate and prove this principle in a new framework, in causal perturbation theory with localized interactions. Throughout this work a universal formulation of symmetries is used: the Master Ward Identity.

description: For the first time, the dielectric response of a BaTiO3 thin film under an AC electric field is investigated using time-resolved X-ray absorption spectroscopy at the Ti K-edge to clarify correlated contributions of each constituent atom on the electronic states. Intensities of the pre-edge eg peak and shoulder structure just below the main edge increase with an increase in the amplitude of the applied electric field, whereas that of the main peak decreases in an opposite manner. Based on the multiple scattering theory, the increase and decrease of the eg and main peaks are simulated for different Ti off-center displacements. Our results indicate that these spectral features reflect the inter- and intra-atomic hybridization of Ti 3d with O 2p and Ti 4p, respectively. In contrast, the shoulder structure is not affected by changes in the Ti off-center displacement but is susceptible to the effect of the corner site Ba ions. This is the first experimental verification of the dynamic electronic contribution of Ba to polarization reversal.

description: Let P(x,y) be a rational polynomial and k in Q be a generic value. If the curve (P(x,y)=k) is irreducible and admits an infinite number of points whose coordinates are integers then there exist algebraic automorphisms that send P(x,y) to the polynomial x or to x^2-dy^2. Moreover for such curves (and others) we give a sharp bound for the number of integral points (x,y) with x and y bounded.

description: To describe the weak three-body B decays into pi+ pi- K, we recently derived amplitudes based on two-body QCD factorization followed by pi+ pi- final state interactions in isoscalar S- and isovector P-waves. We study here the sensitivity of the results to the values of the B to f0(980) transition form factor and to the effective decay constant of the f0(980).

Coin Flipping in Dynamic Programming is Almost Useless

description: We consider probabilistic circuits working over the real numbers, and using arbitrary semialgebraic functions of bounded description complexity as gates. In particular, such circuits can use all arithmetic operations +, -, x, /, optimization operations min and max, conditional branching (if-then-else), and many more. We show that probabilistic circuits using any of these operations as gates can be simulated by deterministic circuits with only about a quadratical blowup in size. A not much larger blow up in circuit size is also shown when derandomizing approximating circuits. The algorithmic consequence, motivating the title, is that randomness cannot substantially speed up dynamic programming algorithms.

description: O nematoide das lesões radiculares (Pratylenchus brachyurus) é considerado um dos principais patógenos da cultura da soja do cerrado brasileiro. O objetivo deste trabalho foi avaliar o potencial de diferentes espécies de fungos no manejo de P. brachyurus na soja. O delineamento experimental foi inteiramente casualizado, em esquema fatorial (4 x 4 + 2), constituído por quatro espécies de fungos: Beauveria bassiana, Trichoderma harzianum, Metarhizium anisopliae e Paecilomyces lilacinus, com quatro formas de aplicação (na semente, no sulco, semente + sulco e cobertura) e duas testemunhas adicionais (água e nematicida), com cinco repetições. Plantas de soja cv. Soy Tech 820 RR foram inoculadas com 50000 ovos e juvenis de segundo estádio (J2) de P. brachyurus. Após 60 dias da aplicação dos tratamentos, foram realizadas avaliações de parasitismo e características agronômicas na soja. Os fungos empregados no controle, influenciaram positivamente em quase todas as características vegetativas das plantas, promovidas pela redução acentuada do número de juvenis na raiz e no solo e, principalmente, pela diminuição no número de ovos nas raízes. A forma de aplicação não influenciou diretamente a ação dos agentes de biocontrole, e todos os microrganismos se comportaram de maneira protetora, inviabilizando ou retardando o parasitismo dos nematoides sobre as raízes das plantas.

description: Anemia is prevalent in hemodialysis (HD) patients. Data about factors associated with medication non-adherence in anemic HD patients is limited. This study examined determinants of medication non-adherence and its association with achievement of therapeutic goals of anemia measures among HD patients. A cross-sectional study was conducted among a representative group of HD patients in Jordan. Medication adherence was assessed using Morisky Green Levine Medication Adherence Scale (MGL). Other utilized instruments were modified Charlson Comorbidity Index (mCCI), general Health-Related Quality of Life (HRQoL) EQ-5D-5 L, and Hospital Anxiety and Depression Scale (HADS). Pharmacy claim data during the years of (2016–2017) were also retrieved from patients’ medical records. Logistic regression was conducted to identify factors associated with medication non-adherence and achieving therapeutic goals of anemia therapy. More than two-thirds of the participants (69.1%) were found non-adherent and the mean score of MGL scale was 2.4 ± 1.4. The non-adherence rate measured using refill data (69.6%) was comparable to that observed using self-reported MGL instrument. Education level of college or over was significantly associated with lower odds of non-adherence (OR = 0.365, p = 0.036), while complaining of a headache was associated with 2.5-fold risk of medication non-adherence (OR = 2.5, p = 0.017). A trend toward better achievement of iron indices therapeutic goals was observed with improved adherence measured using refill data. Multiple factors such as improved knowledge about prescribed medications was significantly associated with achieving anemia therapeutic goals (p The findings suggest poor medication adherence among HD patients with anemia. Future interventions by health-care providers should target modifiable factors to improve medication adherence and, hence, health outcomes among HD patients with anemia.

description: X-ray magnetic circular dichroism (XMCD) is generally not observed for antiferromagnetic (AFM) states because XMCD signals from the antiparallelly coupled spins cancel each other. In this letter, we theoretically show the presence of an XMCD signal from compensated two-dimensional triangle AFM structures on a Kagome lattice. The calculation reveals the complete correspondence between the XMCD spectra and the sign of the spin chirality: the XMCD signal only appears when the spin chirality is negative. This XMCD signal originates from the different absorption coefficients of the three sublattices reflecting different charge density anisotropies and directions of spin and orbital magnetic moments.

Assessment and management of multispecies multigear fisheries : a case study from San Miguel Bay, the Philippines
Creators: name: Bundy, Alida
Publisher: name: University of British Columbia
Year: 2009

description: This work uses ecological theory to explore the interactions between fishing and the ecosystem and examines the implications for fisheries assessment and management. The multispecies, multigear fishery of San Miguel Bay, the Philippines is used as a case-study. Three approaches were taken. The first was to descriptively and analytically assess the fishery. Catch rates in 1992- 1994 and 1979-1982 were similar, but all other indications are that the fishery suffers from growth, recruitment and ecosystem overfishing. Large scale effort has decreased, but small scale effort has intensified and diversified. The second approach was to model the ecosystem using ECOPATH an equilibrium mass-balance model. The model described a relatively mature and resilient ecosystem, dependent on detrital and benthic flows. Different fishing gears have differential impacts on the ecosystem and these are modified by the interactive effects of predation and competition. In the third approach, a dynamic multispecies model, ECOSIM was used. The impacts of fishing by a multisector fishery on a multispecies resource were dynamically explored under top-down and bottom-up trophic hypotheses. The results demonstrated that the interplay of fishing mortality, species interactions and flow dynamics have profound implications for fisheries assessment and management. The uncertainties concerning the resource dynamics were explored using an adaptive management approach. Four ECOSIM models of the San Miguel Bay were used, top-down, bottom-up, immigration plus top-down and immigration plus bottom-up. Analysis of the EVPI showed that there was no value in learning more about the uncertainty or distinguishing between the different resource models. It was concluded that although an active experimental adaptive management was not worthwhile, adaptive management, using feedback information from the response of the resource to management actions as recommended. This thesis demonstrates the critical importance of an ecosystem-based approach to understanding fisheries dynamics.
