description: This study investigates the reasons which lead the companies to keep simultaneous vertical integrated, third part and hybrid distribution channels. Companies establish different coordination structures, the organizational arrangements, which determine how the agents involved cooperate to the development of distribution activities, according to Transaction Cost Economics and Dynamic Competence. Even choosing different distribution channels, why the company does not establish one single organizational arrangement? What factors may justify the establishment of different arrangements? Possible explanations to those questions have been pointed out in multiple distribution channels. The empirical research indicates that firms establish multiple efficient equilibrium, to take advantage of the better of each one, by minimum coordination cost. The results are specific to distribution activities, but the analysis may be replicable to other activities within the firm, regarding to its coordination.

description: In this work we study the scalar power spectrum and the spectral index for the Starobinsky inflationary model using the phase integral method up-to third-order of approximation. We show that the semiclassical methods reproduce the scalar power spectrum for the Starobinsky model with a good accuracy, and the value of the spectral index compares favorably with observations. Also, we compare the results with the uniform approximation method and the second-order slow-roll approximation.

description: Main sequence stars exhibit a clear rotation-activity relationship, in which rapidly rotating stars drive strong chromospheric/coronal ultraviolet and X-ray emission. While the vast majority of red giant stars are inactive, a few percent exhibit strong ultraviolet emission. Here we use a sample of 133 red giant stars observed by SDSS APOGEE and GALEX to demonstrate an empirical relationship between NUV excess and rotational velocity (vsini). Beyond this simple relationship, we find that NUV excess also correlates with rotation period and with Rossby number in a manner that shares broadly similar trends to those found in M dwarfs, including activity saturation among rapid rotators. Our data also suggest that the most extremely rapidly rotating giants may exhibit so-called "super-saturation", which could be caused by centrifugal stripping of these stars rotating at a high fraction of breakup speed. As an example application of our empirical rotation-activity relation, we demonstrate that the NUV emission observed from a recently reported system comprising a red giant with a black hole companion is fully consistent with arising from the rapidly rotating red giant in that system. Most fundamentally, our findings suggest a common origin of chromospheric activity in rotation and convection for cool stars from main sequence to red giant stages of evolution.

description: We show that the accelerated expansion of the Universe can be viewed as a crossover phenomenon where the Newton constant and the Cosmological constant are actually scaling operators, dynamically evolving in the attraction basin of a non-Gaussian infrared fixed point, whose existence has been recently discussed. By linearization of the renormalized flow it is possible to evaluate the critical exponents, and it turns out that the approach to the fixed point is ruled by a marginal and a relevant direction. A smooth transition between the standard Friedmann--Lemaitre--Robertson--Walker (FLRW) cosmology and the observed accelerated expansion is then obtained, so that $Ω_M \approx Ω_Λ$ at late times.

The results of the models of GARCH type, applied for the prices of the coffee, indicated that the conditional variance of the residues of the models possess unit roots and the same one will not present a behavior of reversion to its historical average with passing of the time, after a shock. This happens because, the coefficients of volatility persistence had been all bigger or next to one

description: We investigate the dynamics of a boundary field coupled to a bulk field with a linear coupling in an anti-de Sitter bulk spacetime bounded by a Minkowski (Randall-Sundrum) brane. An instability criterion for the coupled boundary and bulk system is found. There exists a tachyonic bound state when the coupling is above a critical value, determined by the masses of the brane and bulk fields and AdS curvature scale. This bound state is normalizable and localised near the brane, and leads to a tachonic instability of the system on large scales. Below the critical coupling, there is no tachyonic state and no bound state. Instead, we find quasi-normal modes which describe stable oscillations, but with a finite decay time. Only if the coupling is tuned to the critical value does there exist a massless stable bound state, as in the case of zero coupling for massless fields. We discuss the relation to gravitational perturbations in the Randall-Sundrum brane-world.

description: This study addresses unsupervised subword modeling, i.e., learning feature representations that can distinguish subword units of a language. The proposed approach adopts a two-stage bottleneck feature (BNF) learning framework, consisting of autoregressive predictive coding (APC) as a front-end and a DNN-BNF model as a back-end. APC pretrained features are set as input features to a DNN-BNF model. A language-mismatched ASR system is used to provide cross-lingual phone labels for DNN-BNF model training. Finally, BNFs are extracted as the subword-discriminative feature representation. A second aim of this work is to investigate the robustness of our approach's effectiveness to different amounts of training data. The results on Libri-light and the ZeroSpeech 2017 databases show that APC is effective in front-end feature pretraining. Our whole system outperforms the state of the art on both databases. Cross-lingual phone labels for English data by a Dutch ASR outperform those by a Mandarin ASR, possibly linked to the larger similarity of Dutch compared to Mandarin with English. Our system is less sensitive to training data amount when the training data is over 50 hours. APC pretraining leads to a reduction of needed training material from over 5,000 hours to around 200 hours with little performance degradation.

The role of serine and metalloproteinases in silica and coal dust induced connective tissue breakdown
Creators: name: Zay, Katalin
Publisher: name: University of British Columbia
Year: 2009

description: The exposure of the lung to silica and coal dusts causes acute inflammation and the recruitment of neutrophils and macrophages to the site of the injury. Upon activation both cell types are able to release a series of potent substances such as oxygen radicals and proteinases that can damage lung cells and break down the components of the lung's extracellular matrix. The aim of this study was to test the hypothesis that different dusts provoke different inflammatory responses, meaning that macrophages and neutrophils react differently depending on the nature of the dust, therefore the damage causing proteinase profiles of these two cell types are consequently different for each dust. The experimental model in this study consisted of C57B1/6 mice exposed to intratracheal instillation of silica and coal dusts. The mice were examined for recruitment of neutrophils and macrophages into the lung. The bronchoalveolar lavage fluids were tested by HPLC for connective tissue breakdown products originating from collagen and elastin fibers (hydroxyproline and desmosine respectively). The lung tissue was categorized into 'lung tissue',' bronchoalveolar lavage fluid' and 'cells that were washed out with the lavage fluid'. Each fraction was tested for collagenolytic and elastolytic activity of serine and metalloproteinases by gelatin, casein and Kelastin zymographies. The a-l antitrypsin levels and elastase inhibitory capacity were measured in the bronchoalveolar lavage fluids. The results showed that the primary response to silica dust damage to the lung was led by neutrophils, and after fourteen days both neutrophils and macrophages played role in the process of inflammation. In case of coal dust exposure after an initial rapid neutrophil recruitment to the site of injury the inflammatory response seemed to be mediated almost exclusively by macrophages. The levels of hydroxyproline increased after silica and coal induced injury similarly to the number of macrophages. The desmosine levels showed direct relationship with the neutrophil numbers after both silica and coal dust induced injury. In the lung tissue and in the bronchoalveolar lavage fluid after both silica and coal dust exposure the increase in 92 kD gelatinase levels showed direct correlation with the increase of the number of neutrophils present in the lavage fluid. The 72 kD gelatinase levels showed no close relationship with macrophage numbers, suggesting that in addition to macrophages, other cells of the lung tissue, such as fibroblasts, epithelial and endothelial cells may be responsible for the increased levels of this enzyme. The study showed that both neutrophils and macrophages play role in silica and coal dust induced lung injury, but the respective patterns of the mflarnmation and the damage-causing proteinase profile for both dusts is different.

For large $x$ small di- or tri-vacancy clusters are stable with respect to isolated Na vacancies. At commensurate fillings these small clusters order in triangular superstructures. These results agree with recent electron diffraction data at $x=1/2$ and 3/4. We have performed neutron Laüe diffraction experiments at higher $x$, which confirm the predictions of this simple model. The consequences on the properties of the electronic charges in the Co layers are discussed.

description: The Zwicky Transient Facility has begun to discover binary systems with orbital periods that are less than 1\,hr. Combined with dedicated follow-up systems, which allow for high-cadence photometry of these sources, systematic confirmation and characterization of these sources are now possible. Here, we report the discovery of ZTF J190125.42+530929.5, a 40.6\,min orbital period, eclipsing double white-dwarf binary. Both photometric and spectroscopic modeling confirm its nature, yielding an estimated inclination of $i = 86.2^{+0.6}_{-0.2}\,\rm degrees$ and primary and secondary effective temperatures of $\textrm{T}_\textrm{eff} = 28,000^{+500}_{-500}\,K$ and $\textrm{T}_\textrm{eff} = 17,600^{+400}_{-400}\,K$ respectively. This system adds to a growing list of sources for future gravitational-wave detectors and contributes to the demographic analysis of double degenerates.

description: From the 1990s on, the sugar alcohol agro industry has been undergoing an intense process of merging and acquisition. The regions of Triângulo Mineiro and Alto Paranaíba - Minas Gerais have received significant investment directed to sugar- alcohol activities. This work aimed to analyze the major determinants in the sugar alcohol agro industry competitivity in the regions of Triângulo Mineiro and Alto Paranaíba, by verifying two determinants: inputs and market structure and relationships. The model of competitivity determinant factors of Duren et al. (1991) was applied, adapted to the method used in studies on fruit (UFV, 2001) and meat (SILVA & BATALHA, 1999) chains, etc. The analysis of the behavior of each factor showed that among the positive competitivity aspects presented by these mills and distilleries in terms of the raw material, sugar cane are the advantages of raw material availability and price negotiation. However, these mills and distilleries present some liabilities in relation to some elements downstream and upstream the sugar alcohol chain, such as the large concentration of agricultural input suppliers and alcohol distributors. Finally, they also undergo difficulties due to the competition of São Paulo companies.

description: We present a way to realize a $n$-qubit controlled phase gate with superconducting quantum interference devices (SQUIDs) by coupling them to a superconducting resonator. In this proposal, the two logical states of a qubit are represented by the two lowest levels of a SQUID. An intermediate level of each SQUID is utilized to facilitate coherent control and manipulation of quantum states of the qubits. It is interesting to note that a $n$-qubit controlled phase gate can be achieved with $n$ SQUIDs by successively applying a $π/2$ Jaynes-Cummings pulse to each of the $n-1$ control SQUIDs before and after a $π$ Jaynes-Cummings pulse on the target SQUID.

description: We present a study of the mass transfer and wind outflows of SS433, focusing on the so-called stationary lines based on archival high and low resolution optical spectra, and new optical multifilter polarimetry and low resolution optical spectra spanning an interval of a decade and a broad range of precessional and orbital phases. We derive $\text{E(B-V)}=0.86\pm0.10$ and revised UV and U band polarizations and polarization angles that yield the same position angle as the optical. The polarization wavelength dependence is consistent with optical-dominating electron scattering with a Rayleigh component in U and the UV filters; no polarization changes were observed during a flare event. Using profile orbital and precessional modulation of multiple lines we derive properties for the accretion disk, present evidence for a strong disk wind, determine its velocity structure, and demonstrate its variability on timescales unrelated to the orbit. We derive a mass ratio $q=0.37\pm0.04$, and masses $\text{M}_X=4.2\pm0.4\ \text{M}_\odot$, $\text{M}_A=11.3\pm 0.6\ \text{M}_\odot$, and show that the A star fills its Roche surface. The O I 7772 Å and 8446 Å lines show different but related orbital modulation and no evidence for a circumbinary disk component. Instead, the spectral line profile variability can be understood with an ionization stratified outflow predicted by thermal wind modeling, which also accounts for an extended equatorial structure detected at long wavelength.

description: This work focuses on the development of planar microwave resonators which are to be used in electron spin resonance spectroscopic studies. Two half wavelength microstrip resonators of different geometrical shapes, namely straight ribbon and omega, are fabricated on commercially available copper clad microwave laminates. Both resonators have a characteristic impedance of 50 Ω. We have performed electromagnetic field simulations for the two microstrip resonators and have extracted practical design parameters which were used for fabrication. The effect of the geometry of the resonators on the quasi-transverse electromagnetic (quasi-TEM) modes of the resonators is noted from simulation results. The fabrication is done using optical lithography technique in which laser printed photomasks are used. This rapid prototyping technique allows us to fabricate resonators in a few hours with accuracy up to 6 mils. The resonators are characterized using a Vector Network Analyzer. The fabricated resonators are used to standardize a home built low-temperature continuous wave electron spin resonance (CW-ESR) spectrometer which operates in S-band, by capturing the absorption spectrum of the free radical DPPH, at both room temperature and 77 K. The measured value of g-factor using our resonators is consistent with the values reported in literature. The designed half wavelength planar resonators will be eventually used in setting up a pulsed electron spin resonance spectrometer by suitably modifying the CW-ESR spectrometer.

description: Polarization behaviors of optical afterglows from two-component gamma-ray burst jets are investigated, assuming various configurations for the two components. In most cases, the observed polarization is dominated by the inner narrow component for a long period. Interestingly, it is revealed that different assumptions about the lateral expansion of the jet can lead to different evolutions of the position angle of polarization. The observed afterglow light curve and polarization behaviors of GRB 020813 can be well explained by the two-component jet model. Particularly, the model is able to explain the constancy of the observed position angle in this event, given that the line of sight is slightly outside the narrow component.

description: The agriculture of São Paulo State, Brazil, has been increased its productivity and in some years of the 90’s the increasing was the double of average for the all country. The objective of this paper is to measure the factors total productivity (FTP) of cotton, rice, bean, corn and soybean on São Paulo State, for the period of 1985 to 2001. Specifically, it is checked if the increasing on productivity for those crops came from gains in efficiency or technological change and if there are differences between the periods separated by the brazilian economy opening, occurred in 1990. This study is based on the technical efficiency measure with output orientation and it is applied the Data Envelopment Analysis as analytical method. The results show that the increasing on productivity occurred because both gains in efficiency and technological change. The technological change had more influence on the second period, mainly for exportables crops. It was concluded that the commercial opening occurred in 1990 had a positive influence on factors total productivity of the agriculture of São Paulo State.

description: Time-dependent current of the electrons excited in the conduction band after ultrafast interband photogeneration is studied theoretically. The transient photocurrent is calculated for the nonlinear regime of response to a stationary electric field. The response demonstrates transient absolute negative conductivity when the electrons are excited slightly below the optical phonon energy, while the periodic oscillations of the electric current appear after formation of the streaming distribution. The quenching of these peculiarities by the elastic scattering of electrons is also considered.

description: Total internal reflection fluorescence microscopy (TIRF) has enabled low-background, live-cell friendly imaging of cell surfaces and other thin samples thanks to the shallow penetration of the evanescent light field into the sample. The implementation of TIRF on optical waveguide chips (c-TIRF) has overcome historical limitations on the magnification and field of view (FOV) compared to lens-based TIRF, and further allows the light to be guided in complicated patterns that can be used for advanced imaging techniques or selective stimulation of the sample. However, the opacity of the chips themselves has thus far precluded their use on inverted microscopes and complicated sample preparation and handling. In this work, we introduce a new platform for c-TIRF imaging based on a transparent substrate, which is fully compatible with sample handling and imaging procedures commonly used with a standard #1.5 glass coverslip, and is fabricated using standard complementary metal-oxide-semiconductor (CMOS) techniques, which can easily be scaled up for mass production. We demonstrate its performance on synthetic and biological samples using both upright and inverted microscopes, and show how it can be extended to super-resolution applications, achieving a resolution of 116 nm using super resolution radial fluctuations (SRRF). These new chips retain the scalable FOV of opaque chip-based TIRF and the high axial resolution of TIRF, and have the versatility to be used with many different objective lenses, microscopy methods, and handling techniques. We thus see c-TIRF as a technology primed for widespread adoption, increasing both TIRF's accessibility to users and the range of applications that can benefit from it.
Scaling in the Inter-Event Time of Random and Seasonal Systems

description: Interevent times have been studied across various disciplines in search for correlations. In this paper we show analytical and numerical evidence that at the population level a power-law can be obtained by assuming poissonian agents with different characteristic times, and at the individual level by assuming poissonian agents that change the rates at which they perform an event in a random or deterministic fashion. The range in which we expect to see this behavior and the possible deviations from it are studied by considering the shape of the rate distribution.

description: Dispersionless bands -- flatbands -- have been actively studied thanks to their interesting properties and sensitivity to perturbations, which makes them natural candidates for exotic states. In parallel non-Hermitian systems have attracted much attention in the recent years as a simplified description of open system with gain or loss motivated by potential applications. In particular, non-Hermitian system with dispersionless energy bands in their spectrum have been studied theoretically and experimentally. Flatbands require in general fine-tuning of Hamiltonian or protection by a symmetry. A number of methods was introduced to construct non-Hermitian flatbands relying either on a presence of a symmetry, or specific frustrated geometries, often inspired by Hermitian models. We discuss a systematic method of construction of non-Hermitian flatbands using 1D two band tight-binding networks as an example, extending the methods used to construct systematically Hermitian flatbands. We show that the non-Hermitian case admits fine-tuned, non-symmetry protected flatbands and provides more types of flatbands than the Hermitian case.

A REGIONAL ANALYSIS OF VEGETABLE PRODUCTION WITH CHANGING DEMAND FOR ROW CROPS USING QUADRATIC PROGRAMMING

description: The purpose of the study was to ascertain the competitive and complementary potential of fresh vegetable production relative to traditional row crop production using a regional partial equilibrium model. It seems clear from the analysis that vegetable crops are not destined in the near future to replace row crops in terms of land utilization. Nevertheless, vegetable crops appear to compete with and complement row crops well as evidenced by substantial increases in production as market share was assumed to increase. However, fresh vegetables cannot be considered as residual enterprises to which producers move when the demand for row crops declines. Even with a simulated 20 percent decrease in the demand for row crops, the acreage of fresh vegetables did not increase.
Evidence for a high mutual inclination between the cold Jupiter and transiting super Earth orbiting $π$ Men

description: $π$ Men hosts a transiting super Earth ($P\approx6.27$ d, $m\approx4.82$ $M_{\oplus}$, $R\approx2.04$ $R_{\oplus}$) discovered by TESS and a cold Jupiter ($P\approx2093$ d, $m \sin I\approx10.02$ $M_{\rm{Jup}}$, $e\approx0.64$) discovered from radial velocity. We use Gaia DR2 and Hipparcos astrometry to derive the star's velocity caused by the orbiting planets and constrain the cold Jupiter's sky-projected inclination ($I_b=41-65^{\circ}$). From this we derive the mutual inclination ($ΔI$) between the two planets, and find that $49^{\circ}< ΔI < 131^{\circ}$ (1$σ$), and $28^{\circ} < ΔI < 152^{\circ}$ (2$σ$). We examine the dynamics of the system using $N$-body simulations, and find that potentially large oscillations in the super Earth's eccentricity and inclination are suppressed by general relativistic precession. However, nodal precession of the inner orbit around the invariable plane causes the super Earth to only transit between 7-22 per cent of the time, and to usually be observed as misaligned with the stellar spin axis. We repeat our analysis for HAT-P-11, finding a large $ΔI$ between its close-in Neptune and cold Jupiter and similar dynamics. $π$ Men and HAT-P-11 are prime examples of systems where dynamically hot outer planets excite their inner planets, with the effects of increasing planet eccentricities, planet-star misalignments, and potentially reducing the transit multiplicity. Formation of such systems likely involves scattering between multiple giant planets or misaligned protoplanetary discs. Future imaging of the faint debris disc in $π$ Men and precise constraints on the stellar spin orientation would provide strong tests for these formation scenarios.

description: A sequential decision-making model was developed, and data from farm-raised catfish production were used to demonstrate its use. Outcomes of sequences of decisions which satisfied chance constraints on ending cash balances were traced through a specified time period. Discrete choice variables were specified due to the fixed nature of pond facilities. Recourse actions specified were sale of production in excess of endogenously determined transfer levels or purchase of inputs to supplement needs of the next production stage. Production activities cannot be changed during the planning period. Only yield variability was considered due to its impact on relative competitiveness among growth stages. Deviations were calculated from endogenously determined target levels based on goal and probability limits.
