description: HST ACS/HRC images in UV (F250W), V (F555W), and I (F814W) resolve three isolated OB associations that lie up to 30 kpc from the stellar disk of the S0 galaxy NGC 1533. Previous narrow-band Halpha imaging and optical spectroscopy showed these objects as unresolved intergalactic HII regions having Halpha luminosities consistent with single early-type O stars. These young stars lie in stripped HI gas with column densities ranging from 1.5 - 2.5 * 10^20 cm^-2 and velocity dispersions near 30 km s^-1. Using the HST broadband colors and magnitudes along with previously-determined Halpha luminosities, we place limits on the masses and ages of each association, considering the importance of stochastic effects for faint (M_V >-8) stellar populations. The upper limits to their stellar masses range from 600 M_sun to 7000 M_sun, and ages range from 2 - 6 Myrs. This analysis includes an updated calculation of the conversion factor between the ionizing luminosity and the total number of main sequence O stars contained within an HII region. The photometric properties and sizes of the isolated associations and other objects in the HRC fields are consistent with those of Galactic stellar associations, open clusters and/or single O and B stars. We interpret the age-size sequence of associations and clustered field objects as an indication that these isolated associations are most likely rapidly dispersing. Furthermore, we consider the possibility that these isolated associations represent the first generation of stars in the HI ring surrounding NGC 1533. This work suggests star formation in the unique environment of a galaxy's outermost gaseous regions proceeds similarly to that within the Galactic disk and that star formation in tidal debris may be responsible for building up a younger halo component.

description: A compact frequency-doubled diode-pumped Nd:YAG master-oscillator power-amplifier laser system with programmable microsecond pulse length has been developed. Analog pulse shaping of the output from a single-frequency continuous-wave Nd:YAG oscillator, and subsequent amplification, allowed the generation of rectangular pulses with pulse lengths on the order of the Nd:YAG fluorescence lifetime. Temporally flat-top pulses of 1064 nm light with 520 mJ pulse energy, 2.6 kW peak power, and 200 $μ$s duration, with linewidth below 10 kHz, were obtained at a repetition rate of 2 Hz. Second harmonic generation in a LBO crystal yielded pulses of 262 mJ and 1.3 kW peak power at 532 nm. The peak power can be maintained within 2.9% over the duration of the laser pulse, and long-term intensity stability of 1.1% was observed. The spatially flat-top beam at 1064 nm used in the amplifier is converted to a Gaussian beam at 532 nm with beam quality factor $M^2=1.41(14)$ during the second harmonic generation. This system has potential as a pump source for Ti:sapphire, dye, or optical parametric amplifiers to generate tunable high-power single-frequency radiation for applications in precision measurements and laser slowing.

description: Disorder and localization have dramatic influence on the topological properties of a quantum system. While strong disorder can close the band gap thus depriving topological materials of topological features, disorder may also induce topology from trivial band structures, wherein topological invariants are shared by completely localized states in real space. Here we experimentally investigate a fundamentally distinct scenario where a topological phase is identified in a critically localized regime, with eigenstates neither fully extended nor completely localized. Adopting the technique of momentum-lattice engineering for ultracold atoms, we implement a one-dimensional, generalized Aubry-André model with off-diagonal quasi-periodic disorder in momentum space, and characterize its localization and topological properties through dynamic observables. We then demonstrate the impact of interactions on the critically localized topological state, as a first experimental endeavour toward the clarification of many-body critical phase, the critical analogue of the many-body localized state.
Force Modulating Dynamic Disorder: Physical Theory of Catch-slip bond Transitions in Receptor-Ligand Forced Dissociation Experiments

description: Recently experiments showed that some adhesive receptor-ligand complexes increase their lifetimes when they are stretched by mechanical force, while the force increase beyond some thresholds their lifetimes decrease. Several specific chemical kinetic models have been developed to explain the intriguing transitions from the "catch-bonds" to the "slip-bonds". In this work we suggest that the counterintuitive forced dissociation of the complexes is a typical rate process with dynamic disorder. An uniform one-dimension force modulating Agmon-Hopfield model is used to quantitatively describe the transitions observed in the single bond P-selctin glycoprotein ligand 1(PSGL-1)$-$P-selectin forced dissociation experiments, which were respectively carried out on the constant force [Marshall, {\it et al.}, (2003) Nature {\bf 423}, 190-193] and the force steady- or jump-ramp [Evans {\it et al.}, (2004) Proc. Natl. Acad. Sci. USA {\bf 98}, 11281-11286] modes. Our calculation shows that the novel catch-slip bond transition arises from a competition of the two components of external applied force along the dissociation reaction coordinate and the complex conformational coordinate: the former accelerates the dissociation by lowering the height of the energy barrier between the bound and free states (slip), while the later stabilizes the complex by dragging the system to the higher barrier height (catch).

In search of an effective inhibitor of glutamate racemase
Creators: name: Yu, Warrick Sze Chung
Publisher: name: University of British Columbia
Year: 2009

description: Glutamate racemase is an enzyme involved in the biosynthesis of peptidoglycan in bacteria. Designing an effective inhibitor of this enzyme can lead to a better understanding of the mechanism employed by this enzyme as well as the development of new antibiotics. A potential inhibitor, 3-(l-hydroxy-2-imidazolyl)propanoic acid, 1, was designed. This compound was synthesized via the construction of an Nhydroxyimidazole ring and the attachment of the glutamate side chain to Position 2 of the ring. A well-established procedure was used in the construction of the imidazole ring involving condensation of hydroxylamine, glyoxal and formaldehyde. However, the attachment of the glutamate side chain involved the introduction of an aldehyde group at Position 2 of the ring and then the attachment of the rest of the side chain via Wittig reaction. Finally, hydrogenation removed the benzyl protecting groups and yielded the desired compound. The potential inhibitor, 1, was then tested with glutamate racemase in a coupled spectrophotometric assay, which involved the use of L-glutamate dehydrogenase and diaphorase as the coupling enzymes. It was found that Compound 1 was a good competitive inhibitor of the coupling enzyme, L-glutamate dehydrogenase, but not of glutamate racemase. The K₁ value of 1 towards L-glutamate dehydrogenase was found to be 1.66 ± 0.52 mM. However, the precise K₁ value towards glutamate racemase was not pursued due to ineffective inhibition. It was suggested that the poor inhibition of 1 towards glutamate racemase was caused by two possible factors. First, the absence of essential charged groups required for substrate binding to the glutamate racemase active site might lead to poor binding of Compound 1. Second, the bulkiness of the imidazole ring might cause steric problems such that the inhibitor could not fit into the glutamate racemase active site.

description: AGeNDA is an Italian acronym which stands for Analysis and Integrated Management of the Farm (Analisi e GEstione iNtegrata Dell'Azienda agraria). It denominates a new software developed by a research project carried out at the Department of Agronomy, Environment and Crop Production (DAAPV, University of Padova) in collaboration with the Environmental Protection Agency of the Veneto Region (ARPAV). Although developed from scratch, the software originates from a past joint research carried out by the two above mentioned institutions in collaboration with the Department of Agricultural Economics and the Center for Farm Financial Management (CFFM) of the University of Minnesota. The joint research started in the early 1990's, focussing on the Planetor software and, in particular, on the evaluation of its potentials for Italy and the development of an Italian version. The source codes and the elaboration procedures of the old and new software tools have nothing in common. Nevertheless, the methodological approach of the two tools is very similar and so is the input structure of the databases. AGeNDA, in fact adopts an approach similar to that of the previous software in utilising an extensive knowledge base about the environment and the production processes (crops and livestock) saved on databases, which are browsed (and edited if required) at the moment of the practical on farm implementation. The paper presents the results, current activities and future prospects of the AGeNDA Project, with the aim of informing the Italian - American group and stimulating possible new collaborations in the future.
Violation of the zeroth law of turbulence in space plasmas

description: The zeroth law of turbulence states that, for fixed energy input into large-scale motions, the statistical steady state of a turbulent system is independent of microphysical dissipation properties. The behavior, which is fundamental to nearly all fluid-like systems from industrial processes to galaxies, occurs because nonlinear processes generate smaller and smaller scales in the flow, until the dissipation -- no matter how small -- can thermalize the energy input. Using direct numerical simulations and theoretical arguments, we show that in strongly magnetized plasma turbulence such as that recently observed by the Parker Solar Probe (PSP) spacecraft, the zeroth law is routinely violated. Namely, when such turbulence is "imbalanced" -- when the large-scale energy input is dominated by Alfvén waves propagating in one direction (the most common situation in space plasmas) -- nonlinear conservation laws imply the existence of a "barrier" at scales near the ion gyroradius. This causes energy to build up over time at large scales. The resulting magnetic-energy spectra bear a strong similarity to those observed in situ, exhibiting a sharp, steep kinetic transition range above and around the ion-Larmor scale, with flattening at yet smaller scales, thus resolving the decade-long puzzle of the position and variability of ion-kinetic spectral breaks in plasma turbulence. The "barrier" effect also suggests that how a plasma is forced at large scales (the imbalance) may have a crucial influence on thermodynamic properties such as the ion-to-electron heating ratio.

description: We show that Gamma Ray Bursts (GRBs) of known redshift and rest frame optical extinction detected by the Swift satellite fully confirm earlier results concerning the distribution of the optical afterglow luminosity at 12 hours after trigger (rest frame time). This distribution is bimodal and relatively narrow, especially for the high luminosity branch. This is intriguing, given that Swift GRBs have, on average, a redshift larger than pre-Swift ones, and is unexpected in the common scenario explaining the GRB afterglow. We investigate if the observed distribution can be the result of selection effects affecting a unimodal parent luminosity distribution, and find that either the distribution is intrinsically bimodal, or most (60 per cent) of the bursts are absorbed by a substantial amount of grey dust. In both cases we suggest that most dark bursts should belong to the underluminous optical family.

Observation of VHE gamma-ray emission from the Active Galactic Nucleus 1ES1959+650 using the MAGIC telecope

description: The MAGIC Cherenkov telescope has observed very high energy (VHE) gamma-ray emission from the Active Galactic Nucleus 1ES1959+650 during six hours in September and October 2004. The observations were carried out alternated with the Crab Nebula, whose data were used as reference source for optimizing gamma/hadron separation and for flux comparison. The data analysis shows VHE gamma-ray emission of 1ES1959+650 with ~ 8 sigma significance, at a time of low activity in both optical and X-ray wavelengths. An integral flux above ~ 180 GeV of about 20% of the Crab was obtained. The light curve, sampled over 7 days, shows no significant variations. The differential energy spectrum between 180 GeV and 2 TeV can be fitted with a power law of index -2.72 +/- 0.14. The spectrum is consistent with the slightly steeper spectrum seen by HEGRA at higher energies, also during periods of low X-ray activity.

description: Recent studies have established that the anti-Stokes Raman signal from plasmonic metal nanostructures can be used to determine the two separate temperatures that characterize carriers inside the metal -- the temperature of photoexcited "hot carriers" and carriers that are thermalized with the metal lattice. However, the related signal in the Stokes spectral region has historically impeded surface enhanced Raman spectroscopy (SERS), as the vibrational peaks of adsorbed molecules are always accompanied by the broad background of the metal substrate. The fundamental source of the metal signal, and hence its contribution to the spectrum, has been unclear. Here, we outline a unified theoretical model that describes both the temperature-dependent behavior and the broad spectral distribution. We suggest that the majority of the Raman signal is from inelastic scattering directly with non-thermal carriers that have been excited via damping of the surface plasmon. In addition, a significant spectral component (~ 1%) is due to a sub-population of hot carriers in an elevated thermal distribution. We have performed temperature and power-dependent Raman experiments to show how a simple fitting procedure reveals the plasmon dephasing time, as well as the temperatures of the hot carriers and the metal lattice, in order to correlate these parameters with quantitative Raman analysis of chemical species adsorbed on metal surface.

description: The 1996 Fair Act authorized two types of income support payments for the major commodities, fixed decoupled payments, and marketing assistance loans. These provided a lower safety net for commodity programs than was political acceptable, and Congress passed emergency legislation providing supplemental market loss assistance annually beginning in 1998. By 2001, many in Congress and members of farm commodity groups argued new legislation was needed that provides a higher safety net for farm income. The outcome of this discussion was passage of the 2002 Farm Act, which provides three types of payments. They are fixed payments (extended to include oilseeds), a marketing assistance loan program, and a new counter-cyclical payments program to replace the emergency market loss assistance. The estimated payments under the 2002 Act exceed the level of expenditures authorized by the FAIR Act, but they do not exceed the combined expenditures of the FAIR Act and the supplemental programs the U.S. funded in recent years. However, the authorization of the new counter-cyclical payments as a substitute for the supplemental market loss assistance payments may create problems for U.S. ability to meet its WTO obligations. The conservation and rural development titles received a great deal of discussion during the debate on the legislation in the Senate, but the authorization, while increased significantly for the conservation title, is disappointing for both titles. The additional concern is that the 2002 Farm Act is just the authorizing legislation. The amounts appropriated for titles II and III may be less than the authorization.

We also characterize the parity of the degrees of projective varieties of $n\times n$ complex skew symmetric matrices of rank at most $2p$. We give recursive relations which determine the parity of the degrees of projective varieties of $m\times n$ complex matrices of rank at most $k$. In the case the degrees of these varieties are odd, we characterize the minimal dimensions of subspaces of $n\times n$ skew symmetric real matrices and of $m\times n$ real matrices containing a nonzero matrix of rank at most $k$. The parity questions studied here are also of combinatorial interest since they concern the parity of the number of plane partitions contained in a given box, on the one hand, and the parity of the number of symplectic tableaux of rectangular shape, on the other hand.

description: This brief is divided into four parts. Part one provides a basic description of the agricultural production process as a dynamic flow, producing not only commodities but environmental goods and "bads"(damages). Part two discusses the research agendas that have influenced this production process, and the conflicts between traditional commodity oriented research and the newer environmental research agenda. Part three takes up the common ground uniting these two agendas: a concern for the uses of land and the effects of this use on both commodity and environmental flows. Part four offers some specific recommendations for reforms in land policy and targeting at the national level, the farm level, and the implications of these reforms for agricultural research systems.

description: Surface water pollution caused a growing concern for environmental damages (algine bloom, waterlife reduction, etc.) mostly for some aspects connected to public health (through the food chain or directly to water management), to crops and to soils (loss of fertility and foodstuff production capacity) especially given by the accumulation of toxic substances. In 1991 the Veneto Region Land Reclamation Union began to cooperate with ESAV in order to carry out an investigation on water quality conditions to optimize its use and to prevent pollution.

description: Free electron beams such as those employed in electron microscopes have evolved into powerful tools to investigate photonic nanostructures with an unrivaled combination of spatial and spectral precision through the analysis of electron energy losses and cathodoluminescence light emission. In combination with ultrafast optics, the emerging field of ultrafast electron microscopy utilizes synchronized femtosecond electron and light pulses that are aimed at the sampled structures, holding the promise to bring simultaneous sub-Angstrom--sub-fs--sub-meV space-time-energy resolution to the study of material and optical-field dynamics. In addition, these advances enable the manipulation of the wave function of individual free electrons in unprecedented ways, opening sound prospects to probe and control quantum excitations at the nanoscale. Here, we provide an overview of photonics research based on free electrons, supplemented by original theoretical insights, and discussion of challenges and opportunities. In particular, we show that the excitation probability by a single electron is independent of its wave function, apart from a classical average over the transverse beam density profile, whereas the probability for two or more modulated electrons depends on their relative spatial arrangement, thus reflecting the quantum nature of their interactions. We derive first-principles analytical expressions that embody these results and have general validity for arbitrarily shaped electrons and any type of electron-sample interaction. We conclude with perspectives on various exciting directions for disruptive approaches to non-invasive spectroscopy and microscopy, the possibility of sampling the nonlinear optical response at the nanoscale, the manipulation of the density matrices associated with free electrons and optical sample modes, and applications in optical modulation of electron beams.

description: Because the propagators of flavor-singlet states incorporate disconnected diagrams, they are uniquely sensitive to any differences in the actions governing sea and valence fermions on the lattice. As such, they present an important test of the validity of the ``fourth-root trick'' in the staggered fermion formulation. The pseudoscalar's relationship to topological charge also makes it of theoretical interest. We present preliminary results from our measurements of flavor-singlet pseudoscalar mesons on 2+1 flavor Asqtad lattices, and discuss some strategies for improving the signal-to-error ratio of disconnected singlet correlators.

Lectures on Nehari's Theorem on the Polydisk

description: We give a leisurely proof of a result of Ferguson--Lacey (math.CA/0104144) and Lacey--Terwelleger (math.CA/0601192) on a Nehari theorem for "little" Hankel operators on a polydisk. If H_b is a little Hankel operator with symbol b on product Hardy space we have || H_b || \simeq || b ||_{BMO} where BMO is the product BMO space identified by Chang and Fefferman. This article begins with the classical Nehari theorem, and presents the necessary background for the proof of the extension above. The proof of the extension is an induction on parameters, with a bootstrapping argument. Some of the more technical details of the earlier proofs are now seen as consequences of a paraproduct theory.

Oscillations of Thick Accretion Discs Around Black Holes - II

Year: 2005

description: We present a numerical study of the global modes of oscillation of thick accretion discs around black holes. We have previously studied the case of constant distributions of specific angular momentum. In this second paper, we investigate (i) how the size of the disc affects the oscillation eigenfrequencies, and (ii) the effect of power-law distributions of angular momentum on the oscillations. In particular, we compare the oscillations of the disc with the epicyclic eigenfrequencies of a test particle with different angular momentum distributions orbiting around the central object. We find that there is a frequency shift away from the epicyclic eigenfrequency of the test particle to lower values as the size of the tori is increased. We have also studied the response of a thick accretion disc to a localized external perturbation using non constant specific angular momentum distributions within the disc. We find that in this case it is also possible (as reported previously for constant angular momentum distributions) to efficiently excite internal modes of oscillation. In fact we show here that the local perturbations excite global oscillations (acoustic p modes) closely related to the epicyclic oscillations of test particles. Our results are particularly relevant in the context of low mass X-ray binaries and microquasars, and the high frequency Quasi-Periodic Oscillations (QPOs) observed in them. Our computations make use of a Smooth Particle Hydrodynamics (SPH) code in azimuthal symmetry, and use a gravitational potential that mimics the effects of strong gravity.

Nematic-Isotropic phase transition in Liquid crystals: a variational derivation of effective geometric motions

Year: 2020
Subjects: subject: Analysis of PDEs (math.AP)

description: In this work, we study the nematic-isotropic phase transition based on the dynamics of the Landau--De Gennes theory of liquid crystals. At the critical temperature, the Landau--De Gennes bulk potential favors the isotropic phase and nematic phase equally. When the elastic coefficient is much smaller than that of the bulk potential, a scaling limit can be derived by formal asymptotic expansions: the solution gradient concentrates on a closed surface evolving by mean curvature flow. Moreover, on one side of the surface the solution tends to the nematic phase which is governed by the harmonic map heat flow into the sphere while on the other side, it tends to the isotropic phase. To rigorously justify such a scaling limit, we prove a convergence result by combining weak convergence methods and the modulated energy method. Our proof applies as long as the limiting mean curvature flow remains smooth.

description: As background for addressing agricultural policy and sustainable development issues, we address in this paper some general issues we believe it important to consider in developing a broad and consistent conceptual framework for the analysis of sustainability. The objective of this paper is to propose a comprehensive conceptual framework for bringing sustainability issues into practical public policy formulation. A "people first" view is proposed: one that assumes that the ultimate purpose of natural resources and the economic system is first the well-being of mankind.

description: We examine the dynamics and X-ray spectrum of the young Type Ia supernova remnant 0509-67.5 in the context of the recent results obtained from the optical spectroscopy of its light echo. Our goal is to estimate the kinetic energy of the supernova explosion using Chandra and XMM-Newton observations of the supernova remnant, thus placing the birth event of 0509-67.5 in the sequence of dim to bright Type Ia supernovae. We base our analysis on a standard grid of one-dimensional delayed detonation explosion models, together with hydrodynamic and X-ray spectral calculations of the supernova remnant evolution. From the remnant dynamics and the properties of the O, Si, S, and Fe emission in its X-ray spectrum we conclude that 0509-67.5 was originated ~400 years ago by a bright, highly energetic Type Ia explosion similar to SN 1991T. Our best model has a kinetic energy of 1.4x10E51 erg and synthesizes 0.97 Msun of 56Ni. These results are in excellent agreement with the age estimate and spectroscopy from the light echo. We have thus established the first connection between a Type Ia supernova and its supernova remnant based on a detailed quantitative analysis of both objects.

description: The discovery of GRB 170817A, the first unambiguous off-axis short gamma-ray burst arising from a neutron star merger, has challenged our understanding of the angular structure of relativistic jets. Studies of the jet propagation usually assume that the jet is ejected from the central engine with a top-hat structure and its final structure, which determines the observed light curve and spectra, is primarily regulated by the interaction with the nearby environment. However, jets are expected to be produced with a structure that is more complex than a simple top-hat, as shown by global accretion simulations. We present numerical simulations of short GRBs launched with a wide range of initial structures, durations and luminosities. We follow the jet interaction with the merger remnant wind and compute its final structure at distances $\gtrsim 10^{11}$~cm from the central engine. We show that the final jet structure, as well as the resulting afterglow emission, depend strongly on the initial structure of the jet, its luminosity and duration. While the initial structure at the jet is preserved for long-lasting SGRBs, it is strongly modified for jets barely making their way through the wind. This illustrates the importance of combining the results of global simulations with propagation studies in order to better predict the expected afterglow signatures from neutron star mergers. Structured jets provide a reasonable description of the GRB 170817A afterglow emission with an off-axis angle $θ_{\rm obs} \approx 22.5^\circ$.

description: A multinomial logit model was estimated and used to analyze the impact of various producer characteristics on the adoption of flow-through and recirculating technology in soft-shelled crab production. Because of the industry's geographic isolation and high turnover rate, data was collected by personal interviews in 1991. The results suggest that increased adoption might be fostered by targeting education programs towards full time, family operated businesses in nontraditional production regions. However, development of effective education programs may be hindered by the lack of a significant relationship between producer adoption decisions and the information provided by university or extension personnel.
