THE CYCLIC AND SIMPLICIAL COHOMOLOGY OF l(N)

Let A = l(Z+) be the unital semigroup algebra of N. We show that the cyclic cohomology groups HCn(A,A′) vanish when n is odd and are one dimensional when n is even (n ≥ 2). Using Connes’ exact sequence, these results are used to show that the simplicial cohomology groups Hn(A,A′) vanish for n ≥ 2. The results obtained are extended to unital algebras l1(S) for some other semigroups of R. 1. Background and definitions In this paper, we continue the work done in [GW], where it was shown that the third simplicial and cyclic cohomology groups of l(Z+) vanish. Let us recall here that while l(Z+), the unital semigroup algebra of N, is not weakly amenable (see the proof of [BCD, Theorem 2.3]), it was shown that H(l(Z+), l(Z+)) [DaDu, Theorem 3.2] and H(l(Z+), l(Z+)) [GW] are zero. These results suggested the conjecture that all of the simplicial cohomology groups of l(Z+) vanish for n ≥ 2. In this paper, we show that this is indeed the case. We prove this through explicit calculations for the cyclic case, showing that all cyclic cohomology groups of odd degrees vanish and that all those of even degrees are one dimensional. We then deduce the result for simplicial cohomology groups of order two and more, using Connes’ exact sequence. We now recall some basic results and introduce our notation. Let A be a Banach algebra and let A′, the dual of A, be a Banach A-bimodule in the usual way. An n-cochain is a bounded n-linear map T from A to A′ which we denote by T ∈ Cn(A,A′). The map δ : Cn(A,A′) → Cn+1(A,A′) is defined by (δT )(a1, . . . , an+1)(a0) = T (a2, a3, . . . , an+1)(a0a1) + n ∑ j=1 (−1)T (a1, a2, . . . , ajaj+1, . . . , an+1)(a0) + (−1)T (a1, . . . , an)(an+1a0) . The n-cochain T is an n-cocycle if δT = 0 and it is an n-coboundary if T = δn−1S for some S ∈ Cn−1(A,A′). The linear space of all n-cocycles is denoted by Zn(A,A′), and the linear space of all n-coboundaries is denoted by Bn(A,A′). We also recall that Bn(A,A′) is a subset of Zn(A,A′) and that the nth-cohomology Received by the editors November 14, 2002 and, in revised form, April 8, 2004. 2000 Mathematics Subject Classification.

Isometries of certain operator spaces

Let X and Y be Banach spaces, and L(X,Y) be the spaces of bounded linear operators from X into Y. In this paper we give full characterization of isometric onto operators of L(X, Y), for a certain class of Banach spaces, that includes l p , 1 < p < ∞. We also characterize the isometric onto operators of L(c 0 ) and K(l 1 ), the compact operators on l 1 . Furthermore, the multiplicative isometric onto operators of L(l 1 ), when multiplication on L(l 1 ) is taken to be the Schur product, are characterized.
Higgs Physics Prospects at the High Luminosity LHC

The High-Luminosity Large Hadron Collider will provide an unprecedented opportunity to study the properties of the Higgs boson and eventually probe for new physics beyond the Standard Model. The large anticipated data sample will allow for more precise investigations of topics already studied with earlier data samples, as well as for studies of processes that are accessible only with the much larger statistics. Rates and signal strengths will be measured for a variety of Higgs boson production and decay modes, allowing extraction of the Higgs boson couplings. Particular final states will allow differential cross-sections to be measured for all production modes, and for studies of the Higgs boson width and CP properties, as well as the tensor structure of its coupling to vector bosons. An important part of the High-Luminosity LHC experimental program will be investigations of the Higgs boson self-coupling, which is accessible via studies of di-Higgs production. In this note the projections of the ATLAS physics reach in the Higgs sector at the High-Luminosity LHC are discussed and some selected analyses are presented.
Climatological characteristics of atmospheric rivers and their inland penetration over the western united states

AbstractNarrow corridors of water vapor transport known as atmospheric rivers (ARs) contribute to extreme precipitation and flooding along the West Coast of the United States, but knowledge of their influence over the interior is limited. Here, the authors use Interim European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-Interim) data, Climate Prediction Center (CPC) precipitation analyses, and Snowpack Telemetry (SNOTEL) observations to describe the characteristics of cool-season (November–April) ARs over the western United States. It is shown that AR frequency and duration exhibit a maximum along the Oregon–Washington coast, a strong transition zone upwind (west) of and over the Cascade–Sierra ranges, and a broad minimum that extends from the “high” Sierra south of Lake Tahoe eastward across the central Great Basin and into the deep interior. East of the Cascade–Sierra ranges, AR frequency and duration are largest over the interior northwest, while AR duration is large compared to .
Effects of photoperiod on the timing of larval wandering in Drosophila melanogaster

ABSTRACT. A rearing method is described that will allow the use of well‐timed larvae of Drosophila melanogaster (Canton S) in physiological investigations. Using a LD 16:8 h cycle and uncrowded rearing conditions, it was shown that photoperiod influences the departure of third instar larvae from the food (i.e. post‐feeding larvae or wandering behaviour). Larval wandering occurs during the scotophase, suggesting a gated event, and does not occur in larvae raised under constant light or in overcrowded cultures reared in a LD 1623 h cycle. Although the data suggest, but do not prove, the existence of circadian gating, the rearing regimen described will provide well‐timed post‐feeding larvae for future studies.
Deep Non-Blind Deconvolution via Generalized Low-Rank Approximation

In this paper, we present a deep convolutional neural network to capture the inherent properties of image degradation, which can handle different kernels and saturated pixels in a unified framework. The proposed neural network is motivated by the low-rank property of pseudo-inverse kernels. We first compute a generalized low-rank approximation for a large number of blur kernels, and then use separable filters to initialize the convolutional parameters in the network. Our analysis shows that the estimated decomposed matrices contain the most essential information of the input kernel, which ensures the proposed network to handle various blurs in a unified framework and generate high-quality deblurring results. Experimental results on benchmark datasets with noise and saturated pixels demonstrate that the proposed algorithm performs favorably against state-of-the-art methods.
The prediction of heterosis based on the phenotypic distance of sweet maize parental lines

A relatively narrow genetic background, limited sources of germplasm that satisfies commercial standards, poorly defined heterotic groups, as well as a small span for yield and quality estimation are reasons for the modest improvement in sweet corn yields in comparison with standard grain quality maize. Therefore, any additional information could be of a great use. Based on the phenotypic characterization according to UPOV descriptor, phenotypic distances of 14 ZP sweet corn inbred lines were evaluated, and clustering was performed. Grouping showed that 9 out of 11 hybrids obtained by crossings of 14 sweet corn inbred lines had parental lines assigned to different subclusters. Two hybrids whose parental components belonged to the same subcluster had some important specific traits, such as early maturity (ZP 111su), and super-sweet germplasm (ZP 407su). Results obtained by this procedure could be of great assistance in the process of selecting parental lines for the future crossings.
Avoiding quantification bias in metabarcoding: Application of a cell biovolume correction factor in diatom molecular biomonitoring

In recent years, remarkable progress has been made in developing environmental DNA metabarcoding. However, its ability to quantify species relative abundance remains uncertain, limiting its application for biomonitoring. In diatoms, although the rbcL gene appears to be a suitable barcode for diatoms, providing relevant qualitative data to describe taxonomic composition, improvement of species quantification is still required. Here, we hypothesized that rbcL copy number is correlated with diatom cell biovolume (as previously described for the 18S gene) and that a correction factor (CF) based on cell biovolume should be applied to improve taxa quantification. We carried out a laboratory experiment using pure cultures of eight diatom species with contrasted cell biovolumes in order to (1) verify the relationship between rbcL copy numbers (estimated by qPCR) and diatom cell biovolumes and (2) define a potential CF. In order to evaluate CF efficiency, five mock communities were created by mixing different amounts of DNA from the eight species, and were sequenced using HTS and targeting the same rbcL barcode. As expected, the correction of DNA reads proportions by the CF improved the congruence between morphological and molecular inventories. Final validation of the CF was obtained on environmental samples (metabarcoding data from 80 benthic biofilms) for which the application of CF allowed differences between molecular and morphological water quality indices to be reduced by 47%. Overall, our results highlight the usefulness of applying a CF factor, which is effective in reducing over‐estimation of high biovolume species, correcting quantitative biases in diatom metabarcoding studies and improving final water quality assessment.
Additional Evidence on Earnings Management and Corporate Governance

The primary purpose of this paper is to analyze the relationship between corporate governance mechanism and earnings management. Specifically, using a sample of 799 large Japanese manufacturing firms from the period 1999 to 2004, we verify the effect of different governance mechanisms, including internal (managerial ownership, ownership concentration and executive stock option) and external (institutional investors ownership, financial institutions and other corporations shareholding), on earnings management. For internal governance mechanisms, this study presents following three results. First, firms with higher managerial ownership are associated with more earnings management. Second, there is a significant U-shaped relationship between ownership concentration and earnings management. Third, executive stock option does not affect the earnings management; the performance-based managerial scheme is not always effective. For external governance mechanisms, this study presents following three results. First, firms with higher institutional investors ownership are associated with less earnings management. Second, there is a significant U-shaped relation between the shareholdings of financial institutions and earnings management. Third, the shareholdings of foreign other corporations have a positive effect on earnings management. Furthermore, the cross-share holdings of other domestic corporations do not affect the earnings management.
Rockfall induced seismic signals: case study in Montserrat, Catalonia

Abstract. After a rockfall event, a usual post event survey includes qualitative volume estimation, trajectory mapping and determination of departing zones. However, quantitative measurements are not usually made. Additional relevant quantitative information could be useful in determining the spatial occurrence of rockfall events and help us in quantifying their size. Seismic measurements could be suitable for detection purposes since they are non invasive methods and are relatively inexpensive. Moreover, seismic techniques could provide important information on rockfall size and location of impacts. On 14 February 2007 the Avalanche Group of the University of Barcelona obtained the seismic data generated by an artificially triggered rockfall event at the Montserrat massif (near Barcelona, Spain) carried out in order to purge a slope. Two 3 component seismic stations were deployed in the area about 200 m from the explosion point that triggered the rockfall. Seismic signals and video images were simultaneously obtained. The initial volume of the rockfall was estimated to be 75 m3 by laser scanner data analysis. After the explosion, dozens of boulders ranging from 10−4 to 5 m3 in volume impacted on the ground at different locations. The blocks fell down onto a terrace, 120 m below the release zone. The impact generated a small continuous mass movement composed of a mixture of rocks, sand and dust that ran down the slope and impacted on the road 60 m below. Time, time-frequency evolution and particle motion analysis of the seismic records and seismic energy estimation were performed. The results are as follows: 1 – A rockfall event generates seismic signals with specific characteristics in the time domain; 2 – the seismic signals generated by the mass movement show a time-frequency evolution different from that of other seismogenic sources (e.g. earthquakes, explosions or a single rock impact). This feature could be used for detection purposes; 3 – particle motion plot analysis shows that the procedure to locate the rock impact using two stations is feasible; 4 – The feasibility and validity of seismic methods for the detection of rockfall events, their localization and size determination are comfirmed.
AN INVESTIGATION OF MARKET ORIENTATION ’ S AND SELECTED PERSONALITY TRAITS ’ RELATIONSHIP WITH DIMENSIONS OF CUSTOMER ORIENTATION IN SALESPERSONS

The idea that practicing an effective market orientation brings success to organizations (Day, 1994) is widespread. Salespersons that practice a customer orientation implement the marketing concept by placing their customers’ interests first (Saxe and Weitz, 1982), but relatively little is known about what influences this type of customer orientation in individuals (Brown, Mowen, Donovan and Licata, 2002). Previous studies have separately focused on organizational influences and personal characteristics which contribute to this salesperson customer orientation (SCO). A gap exists in the literature investigating the simultaneous influences of organizational and personal forces on a customer orientation. This paper addresses this gap by testing the relationships of a firm’s market orientation and the personality traits of gratitude, forgiveness, Agreeableness, and Openness to experience with the individual customer orientation of salespeople. Conceptual Background and Hypotheses Customer and selling orientations
Effects of human full-length amelogenin on the proliferation of human osteoblasts

Objective: Amelogenins are known as a major constituent of the enamel matrix secreted by ameloblasts and play an important role in enamel formation. Amelogenin knockout mice exhibit enhanced osteoblast formation and resorption of tooth cementum. Recent studies have revealed that amelogenins also have cell signaling properties. However, the biological functions of amelogenin in osteoblasts remain unclear. In this study, we examined the effects of recombinant human full-length amelogenin (rh174) on the proliferation of cultured normal human osteoblasts (NHOst). Methods: NHOst cells were cultured and treated with 100 ng/ml rh174. Cell proliferation was evaluated using MTS assay in a time-dependent manner. Expression of Lysosomal-associated membrane protein 1 (LAMP 1), a possible amelogenin receptor, in NHOst cells was analyzed. NHOst cells were cultured and treated with 100 ng/ml rh174 in the presence or absence of LAMP 1-blocking antibody. Cell proliferative activity was analyzed by BrdU assay. Phosphorylation of extracellular signal regulated kinases (ERK) 1/2 was measured by ELISA and western blotting analysis. Results: Proliferation of NHOst cells was enhanced significantly (p<0.01) by treatment with rh174, and was inhibited significantly (p<0.01) by addition of anti-LAMP 1-blocking antibody. In addition, the ratio of phosphorylated ERK1/2 to total ERK1/2 was significantly larger (p<0.01) with rh174 treatment, and was reduced significantly by the addition of anti-LAMP 1-blocking antibody in NHOst cells. Conclusion: These results confirmed that rh174 interacts with LAMP 1, and rh174/LAMP 1 interaction activates the ERK1/2 signaling pathway, enhancing the proliferation activity of NHOst cells.
Rollover, drowning, and discontinuous retreat: Distinct modes of barrier response to sea‐level rise arising from a simple morphodynamic model

We construct a simple morphodynamic model to investigate the long‐term dynamic evolution of a coastal barrier system experiencing sea‐level rise. Using a simplified barrier geometry, the model includes a dynamic shoreface profile that can be out of equilibrium and explicitly treats barrier sediment overwash as a flux. With barrier behavior primarily controlled by the maximum potential overwash flux and the rate of shoreface response, the modeled barrier system demonstrates four primary behaviors: height drowning, width drowning, constant landward retreat, and a periodic retreat. Height drowning occurs when overwash fluxes are insufficient to maintain the landward migration rate required to keep pace with sea‐level rise. On the other hand, width drowning occurs when the shoreface response rate is insufficient to maintain the barrier geometry during overwash‐driven landward migration. During periodic barrier retreat, the barrier experiences oscillating periods of rapid overwash followed by periods of relative stability as the shoreface resteepens. This periodic retreat, which occurs even with a constant sea‐level rise rate, arises when overwash rates and shoreface response rates are large and of similar magnitude. We explore the occurrence of these behaviors across a wide range of parameter values and find that in addition to the maximum overwash flux and the shoreface response rate, barrier response can be particularly sensitive to the sea‐level rise rate and back‐barrier lagoon slope. Overall, our findings contrast with previous research which has primarily associated complex barrier behavior with changes in external forcing such as sea‐level rise rate, sediment supply, or back‐barrier geometry.
One- and two-photon scattering by two atoms in a waveguide

We consider the interaction of one- and two-photon pulses in a waveguide with two two-level systems (TLS) that are also able to interact directly either through an exchange- or a dipole-type interaction. We focus on the system's transport properties and show how the presence of a second TLS increases the control options, especially when direct interactions are also allowed. We also obtain, within a Markov (long pulse) approximation, exact results for the nonlinear or entangled terms that arise in the two-photon case, and discuss both their potential applications and ways to minimize their effects.
An oceanic heat transport pathway to the Amundsen Sea Embayment

Author(s): Rodriguez, AR; Mazloff, MR; Gille, ST | Abstract: © 2016. American Geophysical Union. All Rights Reserved. The Amundsen Sea Embayment (ASE) on the West Antarctic coastline has been identified as a region of accelerated glacial melting. A Southern Ocean State Estimate (SOSE) is analyzed over the 2005–2010 time period in the Amundsen Sea region. The SOSE oceanic heat budget reveals that the contribution of parameterized small-scale mixing to the heat content of the ASE waters is small compared to advection and local air-sea heat flux, both of which contribute significantly to the heat content of the ASE waters. Above the permanent pycnocline, the local air-sea flux dominates the heat budget and is controlled by seasonal changes in sea ice coverage. Overall, between 2005 and 2010, the model shows a net heating in the surface above the pycnocline within the ASE. Sea water below the permanent pycnocline is isolated from the influence of air-sea heat fluxes, and thus, the divergence of heat advection is the major contributor to increased oceanic heat content of these waters. Oceanic transport of mass and heat into the ASE is dominated by the cross-shelf input and is primarily geostrophic below the permanent pycnocline. Diagnosis of the time-mean SOSE vorticity budget along the continental shelf slope indicates that the cross-shelf transport is sustained by vorticity input from the localized wind-stress curl over the shelf break.
The effects of lifting on mobilisation and new assimilation of C and N during regrowth of transplanted Corsican pine seedlings. A dual 13C and 15N labelling approach

Utilisation d'une methode de double marquage 13 C 15 N. Un double marquage a long terme a l'aide d'isotopes stables ( 13 C, 15 N) a ete applique a des plants de pin laricio de Corse âges d'un an afin de marquer leurs reserves carbonees et azotees. Les extremites racinaires blanches des plants ont ensuite ete soient coupees, simulant un arrachage des racines en pepiniere, soient maintenues intactes. Les plants ont alors ete transplantes dans des minirhyzotrons (conteneurs parallelepipediques permettant l'observation de l'allongement des racines) et installes pendant 41 jours dans une chambre climatisee. La dilution isotopique liee a l'entree de C et de N non marques, a ete suivie apres transplantation afin de determiner l'impact de l'arrachage sur la nouvelle croissance et la gestion du C et de 1'N issus des reserves ou de l'assimilation. L'arrachage des racines a abouti a une diminution des croissances aerienne et racinaire. L'assimilation nette de CO 2 et la conductance stomatique ont ete diminuees dans les aiguilles. Cependant, ni le rapport des concentrations intercellulaire foliaire/atmospherique en CO 2 ni le potentiel hydrique de base des aiguilles n'ont ete affectes par l'arrachage. La concentration en glucides non structuraux des plants entiers a diminue. L'allongement de la partie aerienne a debute juste apres transplantation avec utilisation principale de C ancien. Concomitamment, les quantites de C ancien et de glucides ont diminue fortement dans les racines preexistantes. Une mobilisation marquee de 1'N ancien des aiguilles a egalement ete observee. La croissance des nouvelles racines a debute 15 jours apres transplantation avec une utilisation moindre de C et N anciens comparativement a la nouvelle pousse aerienne. Ensuite, les nouveaux organes ont incorpore essentiellement du C et N nouveaux. Apres 41 jours de croissance, les racines contenaient surtout du C et N nouveaux alors que la nouvelle pousse restait riche en N ancien. La diminution de croissance induite par la transplantation a concerne plus les nouvelles racines que la nouvelle pousse, et a resulte moins d'une diminution des reserves disponibles que d'une diminution de l'acquisition et de l'utilisation de C et d'N nouveaux.
