description: The strategy creates assumptions that should reflect the organization and the surrounding environment. The difficulties in the operationalization of the strategy and the lack of resources for the nonprofit sports organization require effective approaches. This study uses the Business Process Management to support the strategy operationalization using improvement actions according to the existing circumstances of each organization. Based on the action research we analyze the existing situation of nonprofit sports organizations and identify the line of actions to achieve the municipality intended outcomes. The lack of financial resources requires the identification of improvements according to the existing resources. The assessment of the concerns and issues related to stakeholders provides a mechanism to clarify which improvement action should be developed considering the involvement of different board members of the organization. The manager training in nonprofit organizations is an important area to target actions to contribute to the development of the nonprofit organizations, increasing their knowledge. Our findings highlight how the proposed approach can be used in nonprofit sports organization to develop an action plan to engage their business objectives according to its environment.

Year: 2018

description: The study aimed to review the literature on the effects related to post-exercise of graduated compression garments (GCGs) use on muscle recovery and delayed onset muscle soreness. The search was performed in Pubmed/Medline, Bireme, Scielo, and Lilacs electronic databases using the following descriptors in English: "compression clothing", "physical exercise", "recovery", "physical activity", "compression stockings" and "delayed onset muscle soreness". The search resulted in 102 articles and after removing duplicates, applying exclusion criteria and checking the reference lists, nine studies fulfilled the criteria and were included in the review. Seven studies associated the use of GCGs with reduction of delayed muscle soreness and improvement in performance after the use of compression clothes. However, the methodological quality of the studies, using PEDro scale, presented an average of 5.1±0.9 points (out of a total of 11 points), classified as intermediate. In conclusion, although the positive effects of using CGCs on improving recovery and reduction of delayed muscle soreness after physical exercises are almost consensual, the insufficient methodological quality of the included studies requires careful consideration of the results.

description: Stress-related psychiatric disorders are more prevalent in women than men. As hypersecretion of the stress neuromediator, corticotropin-releasing factor (CRF) has been implicated in these disorders, sex differences in CRF sensitivity could underlie this disparity. Hyperarousal is a core symptom that is shared by stress-related disorders and this has been attributed to CRF regulation of the locus ceruleus (LC)-norepinephrine arousal system. We recently identified sex differences in CRF 1 receptor (CRF 1) signaling and trafficking that render LC neurons of female rats more sensitive to CRF and potentially less able to adapt to excess CRF compared with male rats. The present study used a genetic model of CRF overexpression to test the hypothesis that females would be more vulnerable to LC dysregulation by conditions of excess CRF. In both male and female CRF overexpressing (CRF-OE) mice, the LC was more densely innervated by CRF compared with wild-type controls. Despite the equally dense CRF innervation of the LC in male and female CRF-OE mice, LC discharge rates recorded in slices in vitro were selectively elevated in female CRF-OE mice. Immunoelectron microscopy revealed that this sex difference resulted from differential CRF 1 trafficking. In male CRF-OE mice, CRF 1 immunolabeling was prominent in the cytoplasm of LC neurons, indicative of internalization, a process that would protect cells from excessive CRF. However, in female CRF-OE mice, CRF 1 labeling was more prominent on the plasma membrane, suggesting that the compensatory response of internalization was compromised. Together, the findings suggest that the LC-norepinephrine system of females will be particularly affected by conditions resulting in elevated CRF because of differences in receptor trafficking. As excessive LC activation has been implicated in the arousal components of stress-related psychiatric disorders, this may be a cellular mechanism that contributes to the increased incidence of these disorders in females. © 2013 Macmillan Publishers Limited.

description: Objective: Little is known about how the biochemical properties of collagen change during tissue regeneration following cartilage damage. In the current study, temporal changes in cartilage repair tissue biochemistry were assessed in a rabbit osteochondral defect. Design: Bilateral full-thickness 3-mm osteochondral trochlear groove defects were created in 54 adult male skeletally mature New Zealand white rabbits, and tissue repair was monitored over 16 weeks. Collagen content, cross-links, lysyl hydroxylation, gene expression, histological grading, and Fourier transform infrared analyses were performed at 2, 4, 6, 8, 12, and 16 weeks. Results: Defect fill occurred at ~4 weeks postinjury; however, histological grading showed that the repair tissue never became normal, primarily due to the presence of fibrocartilage. Gene expression levels of Col1a1 and Col IIaI were higher in the defect compared with adjacent regions. Collagen content in the repair tissue reached the level of normal cartilage at 6 weeks, but it took 12 weeks for the extent of lysine hydroxylation to return to normal. Divalent immature cross-links markedly increased in the early stages of repair. Though the levels gradually diminished thereafter, they never returned to the normal levels. The mature cross-link, pyridinoline, gradually increased with time and nearly reached normal levels by week 16. Infrared imaging data of protein content paralleled the biochemical data. However, collagen maturity, a parameter previously shown to reflect collagen cross-link ratios in bone, did not correlate with the biochemical determination of cross-links in the repair tissue. Conclusion: Collagen biochemical data could provide markers for clinical monitoring in a healing defect. © The Author(s) 2012.

description: We report the first measurement of the parity-violating asymmetry A PV in the elastic scattering of polarized electrons from Pb208. A PV is sensitive to the radius of the neutron distribution (R n). The result A PV=0.656±0.060(stat)±0. 014(syst)ppm corresponds to a difference between the radii of the neutron and proton distributions R n-R p=0.33-0.18+0.16fm and provides the first electroweak observation of the neutron skin which is expected in a heavy, neutron-rich nucleus. © 2012 American Physical Society.

description: We report the hysteresis of optically-pumped nuclear spin polarization and the degree of circular polarization of photoluminescence on the excitation power and electron spin polarization in single InAlAs quantum dots. By increasing (or decreasing) the excitation power at a particular excitation polarization, an abrupt rise (or drop) and a clear hysteretic behavior were observed in the Overhauser shift of the photoluminescence of the exciton and exciton complexes from the same single quantum dot under an external magnetic field of 5 T. However, the degree of circular polarization shows different behaviors between a positively charged exciton and a neutral exciton or biexciton; further, only positively charged exciton exhibits the precisely synchronized change and hysteretic behavior. It is suggested that the electron spin distribution is affected by the flip-flop of electron-nuclear spins. Further, the hysteresis is observed as a function of the degree of circular polarization of the excitation light and its dependence on the excitation power is studied. The saturation of the Overhauser shift after the abrupt rise indicates the almost complete cancellation of the external magnetic field by the nuclear field created within the width that is decided by the correlation time between the electron and the nuclei spin system.

description: The low energy spectrum of a particle in planar honeycomb lattices is conical, which leads to the unusual electronic properties of graphene. In this letter we calculate the quasienergy spectra of a charged particle in honeycomb lattices driven by a strong AC field, which is of fundamental importance for its time-dependent dynamics. We find that depending on the amplitude, direction and frequency of external field, many interesting phenomena may occur, including band collapse, renormalization of velocity of ``light'', gap opening etc.. Under suitable conditions, with increasing the magnitude of the AC field, a series of phase transitions from gapless phases to gapped phases appear alternatively. At the same time, the Dirac points may disappear or change to a line. We suggest possible realization of the system in Honeycomb optical lattices.

description: Context: For three decades, experts have been stressing the importance of law to the effective operation of public health systems. Most recently, in a 2011 report, the Institute of Medicine recommended a review of state and local public health laws to ensure appropriate authority for public health agencies; adequate access to legal counsel for public health agencies; evaluations of the health effects and costs associated with legislation, regulations, and policies; and enhancement of research methods to assess the strength of evidence regarding the health effects of public policies. These recommendations, and the continued interest in law as a determinant of health system performance, speak to the need for integrating the emerging fields of Public Health Law Research (PHLR) and Public Health Systems and Services Research (PHSSR). Methods: Expert commentary. Findings: This article sets out a unified framework for the two fields and a shared research agenda built around three broad inquiries: (1) the structural role of law in shaping the organization, powers, prerogatives, duties, and limitations of public health agencies and thereby their functioning and ultimately their impact on public health ("infrastructure"); (2) the mechanisms through which public health system characteristics influence the implementation of interventional public health laws ("implementation") ; and (3) the individual and system characteristics that influence the ability of public health systems and their community partners to develop and secure enactment of legal initiatives to advance public health ("innovation") . Research to date has laid a foundation of evidence, but progress requires better and more accessible data, a new generation of researchers comfortable in both law and health research, and more rigorous methods. Conclusions: The routine integration of law as a salient factor in broader PHSSR studies of public health system functioning and health outcomes will enhance the usefulness of research in supporting practice and the long-term improvement of system performance. © 2012 Milbank Memorial Fund.

description: Experimental realizations of two qubit entangling gates with trapped ions typically rely on addressing spectroscopically resolved motional sidebands, limiting gate speed to the secular frequency. Fast entangling gates using ultrafast pulsed lasers overcome this speed limit. This approach is based on state-dependent photon recoil kicks from a sequence of counter-propagating, resonant, ultrafast pulse pairs, which can allow sub-microsecond gate speeds. Here we demonstrate a key component of the ultrafast gate protocol, the coherent excitation of a 171Yb+ ion across the 2S1/2-2P1/2 transition with a single near-resonant short optical pulse at 369.53 nm. We achieve a maximum population transfer of 94.3(6)% using a picosecond pulsed laser that can be tuned across the 2S1/2-2P1/2 transition, and 42.53(13)% with 190(7) GHz detuning.

description: We have studied interspecies scattering in an ultracold mixture of 87Rb and 133Cs atoms, both in their lowest-energy spin states. The three-body loss signatures of 30 incoming s- and p-wave magnetic Feshbach resonances over the range 0 to 667 G have been cataloged. Magnetic field modulation spectroscopy was used to observe molecular states bound by up to 2.5 MHz×h. We have created RbCs Feshbach molecules using two of the resonances. Magnetic moment spectroscopy along the magnetoassociation pathway from 197 to 182 G gives results consistent with the observed and calculated dependence of the binding energy on magnetic field strength. We have set up a coupled-channel model of the interaction and have used direct least-squares fitting to refine its parameters to fit the experimental results from the Feshbach molecules, in addition to the Feshbach resonance positions and the spectroscopic results for deeply bound levels. The final model gives a good description of all the experimental results and predicts a large resonance near 790 G, which may be useful for tuning the interspecies scattering properties. Quantum numbers and vibrational wave functions from the model can also be used to choose optimal initial states of Feshbach molecules for their transfer to the rovibronic ground state using stimulated Raman adiabatic passage. © 2012 American Physical Society.

description: We investigate the decoherence properties of a central system composed of two spins 1/2 in contact with a spin bath. The dynamical regime of the bath ranges from a fully integrable integrable limit to complete chaoticity. We show that the dynamical regime of the bath determines the efficiency of the decoherence process. For perturbative regimes, the integrable limit provides stronger decoherence, while in the strong coupling regime the chaotic limit becomes more efficient. We also show that the decoherence time behaves in a similar way. On the contrary, the rate of decay of magnitudes like linear entropy or fidelity does not depend on the dynamical regime of the bath. We interpret the latter results as due to a comparable complexity of the Hamiltonian for both the integrable and the fully chaotic limits.

description: The parity-violating cross-section asymmetry in the elastic scattering of polarized electrons from unpolarized protons has been measured at a four-momentum transfer squared Q2=0.624GeV2 and beam energy E b=3.48GeV to be A PV=-23.80±0.78(stat)±0. 36(syst) parts per million. This result is consistent with zero contribution of strange quarks to the combination of electric and magnetic form factors GEs+0.517GMs=0.003±0.010(stat)±0.004(syst)±0.009(ff), where the third error is due to the limits of precision on the electromagnetic form factors and radiative corrections. With this measurement, the world data on strange contributions to nucleon form factors are seen to be consistent with zero and not more than a few percent of the proton form factors. © 2012 American Physical Society.

description: Technologies have often been observed to improve exponentially over time. In practice this often means identifying a constant known as the doubling time, describing the time period over which the technology roughly doubles in some measure of performance or of performance per dollar. Moore's law is, classically, the empirical observation that the number of electronic components that can be put on a chip doubles every 18 months to 2 years. Today it is frequently stated as the number of computations available per unit of cost. Generalized to the appropriate doubling time, it describes the rate of advancement in many technologies. A frequently noted competitor to Moore's law is known as Wright's law, which has aeronautical roots. Wright's law (also called power law, experience curve and Henderson's law) relates some quality of a manufactured unit (for Wright, airplanes) to the volume of units manufactured. The Wright's law equation expresses the idea that performance - price or a quality metric - improves according to a power of the number produced, or alternatively stated, improves by a constant percentage for every doubling of the total number produced. Does exploration of outer space conform to Moore's law or Wright's law-like behavior? Our results below are broadly consistent with these laws. This is true for many technologies. Although the two laws can make somewhat different predictions, Sahal found that they converge to the same predictions when manufacturing volume increases exponentially over time. When space exploration transitions into an independent commercial sector, as many people hope and expect, spacecraft technology will then likely enter an era of unambiguously exponential advancement.

description: Based on the locality principle of insulating superlattices, we apply the method of Wu to the piezoelectric strains of individual layers under a fixed displacement field. For a superlattice of arbitrary stacking sequence, an accurate model is acquired for predicting piezoelectricity. By applying the model in the superlattices where ferroelectric and antiferrodistortive modes are in competition, functional piezoelectricity can be achieved. A strong nonlinear effect is observed and can be further engineered in the PbTiO 3/SrTiO3 superlattice, and an interface enhancement of piezoelectricity is found in the BaTiO3/CaTiO3 superlattice. © 2012 American Physical Society.
Study of the temperature-dependence of the far-infrared spectrum of (TMA) (I) (TCNQ)

description: The temperature-dependence (20-300K) of the far-infrared spectrum (20-1000cm⁻¹) of Trimethylammonium Iodide Tetracyanoquinodimethane (TMA)(I)(TCNQ) in its ordered phase, has been measured for the first time. Our measurments confirmed the existence of two phase transitions near 150 and 100K. At least three absorption bands are activated below the 150K phase transition. We have assigned two of them to the totally symmetric mode Ag⁹ and Ag¹⁰ of the TCNQ molecule. We have also observed evidence of Brillouin zone splitting, where one band above 150K, split into three, below 150K. Since the conduction band of (TMA)(I)(TCNQ) is 1/3 filled, we have interpreted this result as suggesting that the 150K transition is a Peierls distortion. We also observe a sharp increased in infrared absorption at 365cm⁻¹ and a weaker one at 100cm⁻¹. Since the D.C. conductivity measurments indicates that a 1000cm⁻¹ band gap is present at all temperatures, we interpret these absorption "edges" in terms of transitions between localised states in the band gap. These localised states would be introduced by either chemical impurities or by some randomness in the potential at each TCNQ site.

description: In translating text where sentiment is the main message, human translators give particular attention to sentiment-carrying words. The reason is that an incorrect translation of such words would miss the fundamental aspect of the source text, i.e. the author's sentiment. In the online world, MT systems are extensively used to translate User-Generated Content (UGC) such as reviews, tweets, and social media posts, where the main message is often the author's positive or negative attitude towards the topic of the text. It is important in such scenarios to accurately measure how far an MT system can be a reliable real-life utility in transferring the correct affect message. This paper tackles an under-recognised problem in the field of machine translation evaluation which is judging to what extent automatic metrics concur with the gold standard of human evaluation for a correct translation of sentiment. We evaluate the efficacy of conventional quality metrics in spotting a mistranslation of sentiment, especially when it is the sole error in the MT output. We propose a numerical `sentiment-closeness' measure appropriate for assessing the accuracy of a translated affect message in UGC text by an MT system. We will show that incorporating this sentiment-aware measure can significantly enhance the correlation of some available quality metrics with the human judgement of an accurate translation of sentiment.

Apart from implementing a robust, scalable communication protocol the solution should be accessible with easy to use API that would not require too much of an effort to use it. In this article we present HyperCuP Lightweight Implementation (HLI) which delivers an alternative P2P architecture based on web services. This implementation has already been deployed with diverse systems like JeromeDL, a semantic digital library and FOAFRealm, a distributed identity management system based on social networking. We describe an architecture of the HyperCuP Lightweight Implementation. We show how to deploy it with one¿s own application and how to take advantage of the established hypercube topology.

description: One major sub-domain in the subject of polling public opinion with social media data is electoral prediction. Electoral prediction utilizing social media data potentially would significantly affect campaign strategies, complementing traditional polling methods and providing cheaper polling in real-time. First, this paper explores past successful methods from research for analysis and prediction of the 2020 US Presidential Election using Twitter data. Then, this research proposes a new method for electoral prediction which combines sentiment, from NLP on the text of tweets, and structural data with aggregate polling, a time series analysis, and a special focus on Twitter users critical to the election. Though this method performed worse than its baseline of polling predictions, it is inconclusive whether this is an accurate method for predicting elections due to scarcity of data. More research and more data are needed to accurately measure this method's overall effectiveness.
Sigma terms and strangeness content of the nucleon with N f = 2+1+1 twisted mass fermions

Subjects: hep-lat

description: We investigate excited state contaminations in a direct computation of the nucleon s-terms. This is an important source of systematic effects that needs to be controlled besides the light quark mass dependence and lattice artefacts. We use maximally twisted mass fermions with dynamical light (u,d), strange and charm degrees of freedom. Employing an efficient stochastic evaluation of the disconnected contribution available for twisted mass fermions, we show that the effect of excited states is large in particular for the strange s-terms, where it can be as big as O(and 40%). This leads to the unfortunate conclusion that even with a source-sink separation of -1.5 fm and a good statistical accuracy it is not clear, whether excited state effects are under control for this quantity.
Perturbative subtraction of lattice artifacts in the computation of renormalization constants
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2012
Subjects: hep-lat

description: The determination of renormalization factors is of crucial importance. They relate the observ- ables obtained on finite, discrete lattices to their measured counterparts in the continuum in a suitable renormalization scheme. Therefore, they have to be computed as precisely as possible. A widely used approach is the nonperturbative Rome-Southampton method. It requires, however, a careful treatment of lattice artifacts. They are always present because simulations are done at lattice spacings a and momenta p with ap not necessarily small. In this paper we try to suppress these artifacts by subtraction of one-loop contributions in lattice perturbation theory. We compare results obtained from a complete one-loop subtraction with those calculated for a subtraction of O(a2).

description: We present an implementation of a recently introduced method for estimating the allele-frequency spectrum under the diffusion approximation. For single-nucleotide polymorphism (SNP) frequency data from multiple populations, the method computes numerical solutions to the allele-frequency spectrum (AFS) under a complex model that includes population splitting events, migration, population expansion, and admixture. The solution to the diffusion partial differential equation (PDE) that mimics the evolutionary process is found by means of truncated polynomial expansions. In the absence of gene flow, our computation of frequency spectra yields exact results. The results are compared to those that use a finite-difference method and to forward diffusion simulations. In general, all the methods yield comparable results, although the polynomial-based approach is the most accurate in the weak-migration limit. Also, the economical use of memory attained by the polynomial expansions makes the study of models with four populations possible for the first time. The method was applied to a four-population model of the human expansion out of Africa and the peopling of the Americas, using the Environmental Genome Project (EGP) SNP database. Although our confidence intervals largely overlapped previous analyses of these data, some were significantly different. In particular, estimates of migration among African, European, and Asian populations were considerably lower than those in a previous study and the estimated time of migration out of Africa was earlier. The estimated time of founding of a human population outside of Africa was 52,000 years (95% confidence interval: 36,000-80,800 years). © 2012 by the Genetics Society of America.

description: Sine-Wiener noise is increasingly adopted in realistic stochastic modeling for its bounded nature. However, many features of the SW noise are still unexplored. In this paper, firstly, the properties of the SW noise and its integral process are explored as the parameter $D$ in the SW noise tends to infinite. It is found that although the distribution of the SW noise is quite different from Gaussian white noise, the integral process of the SW noise shows many similarities with the Wiener process. Inspired by the Wiener process, which uses the diffusion coefficient to denote the intensity of the Gaussian noise, a quantity is put forward to characterize the SW noise's intensity. Then we apply the SW noise to a one-dimensional double-well potential system and the Maier-Stein system to investigate the escape behaviors. A more interesting result is observed that the mean first exit time also follows the well-known Arrhenius law as in the case of the Gaussian noise, and the quasi-potential and the exit location distributions are very close to the results of the Gaussian noise.

description: The cosmic evolution of the chemical elements from the Big Bang to the present time is driven by nuclear fusion reactions inside stars and stellar explosions. A cycle of matter recurrently re-processes metal-enriched stellar ejecta into the next generation of stars. The study of cosmic nucleosynthesis and of this matter cycle requires the understanding of the physics of nuclear reactions, of the conditions at which the nuclear reactions are activated inside the stars and stellar explosions, of the stellar ejection mechanisms through winds and explosions, and of the transport of the ejecta towards the next cycle, from hot plasma to cold, star-forming gas. Due to the long timescales of stellar evolution, and because of the infrequent occurrence of stellar explosions, observational studies are challenging. Due to their radioactive lifetime of million years, the 26Al and 60Fe isotopes are suitable to characterise simultaneously the processes of nuclear fusion reactions and of interstellar transport. We describe and discuss the nuclear reactions involved in the production and destruction of 26Al and 60Fe, the key characteristics of the stellar sites of their nucleosynthesis and their interstellar journey after ejection from the nucleosynthesis sites. We connect the theoretical astrophysical aspects to the variety of astronomical messengers, from stardust and cosmic-ray composition measurements, through observation of gamma rays produced by radioactivity, to material deposited in deep-sea ocean crusts and to the inferred composition of the first solids that have formed in the Solar System. We show that considering measurements of the isotopic ratio of 26Al to 60Fe eliminate some of the unknowns when interpreting astronomical results, and discuss the lessons learned from these two isotopes on cosmic chemical evolution.

Evolution of a population of random Boolean networks

description: We investigate the evolution of populations of random Boolean networks under selection for robustness of the dynamics with respect to the perturbation of the state of a node. The fitness landscape contains a huge plateau of maximum fitness that spans the entire network space. When selection is so strong that it dominates over drift, the evolutionary process is accompanied by a slow increase in the mean connectivity and a slow decrease in the mean fitness. Populations evolved with higher mutation rates show a higher robustness under mutations. This means that even though all the evolved populations exist close to the plateau of maximum fitness, they end up in different regions of network space.

Universalities in ultracold reactions of alkali-metal polar molecules

description: We consider ultracold collisions of ground-state heteronuclear alkali-metal dimers that are susceptible to four-center chemical reactions 2AB→A 2+B2 even at submicrokelvin temperatures. These reactions depend strongly on species, temperature, electric field, and confinement in an optical lattice. We calculate ab initio van der Waals coefficients for these interactions and use a quantum formalism to study the scattering properties of such molecules under an external electric field and optical lattice. We also apply a quantum threshold model to explore the dependence of reaction rates on the various parameters. We find that, among the heteronuclear alkali-metal fermionic species, LiNa is the least reactive, whereas LiCs is the most reactive. For the bosonic species, LiK is the most reactive in zero field, but all species considered, LiNa, LiK, LiRb, LiCs, and KRb, share a universal reaction rate once a sufficiently high electric field is applied. For indistinguishable bosons, the inelastic/reactive rate increases as d2 in the quantum regime, where d is the dipole moment induced by the electric field. This is a weaker power-law dependence than for indistinguishable fermions, for which the rate behaves as d6. © 2011 American Physical Society.
Influence of intrinsic electronic properties on light transmission through subwavelength holes on gold and MgB2 thin films

description: We show how intrinsic material properties modify light transmission through subwavelength hole arrays on thin metallic films in the THz regime. We compare the temperature-dependent transmittance of Au films and MgB2 films. The experimental data are consistent with analytical calculations and are attributed to the temperature change of the conductivity of both films. The transmission versus conductivity is interpreted within the open resonator model when taking the skin depth into consideration. We also show that the efficiency of this temperature control depends on the ratio of the transmission peak frequency to the superconducting energy gap in MgB2 films. © 2011 American Physical Society.

description: We have upgraded the 60-cm radio survey telescope located in Nobeyama, Japan. We developed a new waveguide-type sideband-separating SIS mixer for the telescope, which enables the simultaneous detection of distinct molecular emission lines both in the upper and lower sidebands. Over the RF frequency range of 205-240 GHz, the single-sideband receiver noise temperatures of the new mixer are 40-100 K for the 4.0-8.0 GHz IF frequency band. The image rejection ratios are greater than 10 dB over the same range. For the dual IF signals obtained by the receiver, we have developed two sets of acousto-optical spectrometers and a telescope control system. Using the new telescope system, we successfully detected the 12CO (J=2-1) and 13CO (J=2-1) emission lines simultaneously toward Orion KL in 2005 March. Using the waveguide-type sideband-separating SIS mixer for the 200 GHz band, we have initiated the first simultaneous 12CO (J=2-1) and 13CO (J=2-1) survey of the galactic plane as well as large-scale mapping observations of nearby molecular clouds.

description: We briefly report on some recent progress in the computation of B-brane superpotentials for Type II strings compactified on Calabi-Yau manifolds, obtained by using a parametrization of tubular neighborhoods of complex submanifolds, also known as local spaces. In particular, we propose a closed expression for the superpotential of a brane on a genus-g curve in a Calabi-Yau threefold in the case in which there exists a holomorphic projection from the local space around the curve to the curve itself.
