Wind-induced vibration mitigation in tall buildings using the tuned mass-damper-inerter (TMDI)

In this paper the classical linear tuned mass-damper (TMD) is coupled with an inerter, a two-terminal device resisting the relative acceleration of its terminals, in various tuned mass-damper-inerter (TMDI) topologies to suppress excessive wind-induced oscillations in tall buildings causing occupants’ discomfort. A parametric numerical study is undertaken involving a top-floor-TMD-equipped planar frame capturing accurately the in-plane dynamic behavior of a 74-storey benchmark building exposed to a quasi-stationary spatially-correlated wind-force field accounting for vortex shedding effects in the across-wind direction. It is found that the TMDI reduces the peak top floor acceleration more effectively than the TMD by considering smaller attached mass values, and TMDI topologies in which the inerter spans more stories in linking the attached mass to the host structure. Moreover, the inclusion of the inerter reduces dramatically the TMD stroke while it was verified that the magnitude of the developing inerter forces can be readily accommodated by the host structure. Pertinent illustrative examples are included showcasing that the TMDI meets code-prescribed serviceability design requirements for new tall buildings using significantly smaller attached mass compared to the TMD, and that inerter devices can be used to upgrade the performance of existing TMD-equipped tall buildings without changing the attached mass
Observational hints for radial migration in disc galaxies from CALIFA

Context: According to numerical simulations, stars are not always kept at
their birth galactocentric distances but migrate. The importance of this radial
migration in shaping galactic light distributions is still unclear. However, if
it is indeed important, galaxies with different surface brightness (SB)
profiles must display differences in their stellar population properties. Aims:
We investigate the role of radial migration on the light distribution and the
radial stellar content by comparing the inner colour, age and metallicity
gradients for galaxies with different SB profiles. We define these inner parts
avoiding the bulge and bar regions and up to around three disc scale-lengths
(type I, pure exponential) or the break radius (type II, downbending; type III,
upbending). Methods: We analyse 214 spiral galaxies from the CALIFA survey
covering different SB profiles. We make use of GASP2D and SDSS data to
characterise their light distribution and obtain colour profiles. The stellar
age and metallicity profiles are computed using a methodology based on
full-spectrum fitting techniques (pPXF, GANDALF, and STECKMAP) to the IFS
CALIFA data. Results: The distributions of the colour, stellar age and stellar
metallicity gradients in the inner parts for galaxies displaying different SB
profiles are unalike as suggested by Kolmogorov-Smirnov and Anderson-Darling
tests. We find a trend in which type II galaxies show the steepest profiles of
all and type III the shallowest, with type I galaxies displaying an
intermediate behaviour. Conclusions: These results are consistent with a
scenario in which radial migration is more efficient for type III galaxies than
for type I systems with type II galaxies presenting the lowest radial migration
efficiency. In such scenario, radial migration mixes the stellar content

AGN-host connection at 0.5 < z < 2.5 : a rapid evolution  of AGN fraction in red galaxies during the last 10 Gyr.

We explore the dependence of the incidence of moderate-luminosity (L0.5−8 keV = 1041.9−43.7 erg s-1) active galactic nuclei (AGNs) and the distribution of their accretion rates on host color at 0.5 <z < 2.5. Based on the deepest X-ray and UV-to-far-infrared data in the two The Great Observatories Origins Deep Survey (GOODS) fields, we identify 221 AGNs within a mass-complete parent galaxy sample down to M∗ > 1010 M⊙. We use extinction-corrected rest-frame U−V colors to divide both AGN hosts and non-AGN galaxies into red sequence (red), green valley (green), and blue cloud (blue) populations. We find that the fraction of galaxies hosting an AGN at fixed X-ray luminosity increases with stellar mass and redshift for all the three galaxy populations, independent of their colors. However, both the AGN fraction at fixed stellar mass and its evolution with redshift are clearly dependent on host colors. Most notably, red galaxies have the lowest AGN fraction (~5%) at z ~ 1 yet with most rapid evolution with redshift, increasing by a factor of ~5 (24%) at z ~ 2. Green galaxies exhibit the highest AGN fraction across all redshifts, which is most pronounced at z ~ 2 with more than half of them hosting an AGN at M∗ > 1010.6 M⊙. Together with the high AGN fraction in red galaxies at z ~ 2, this indicates that (X-ray) AGNs could be important in both transforming (quenching) star-forming galaxies into quiescent ones and subsequently maintaining their quiescence at high redshift. Furthermore, consistent with previous studies at lower redshifts, we show that the probability of hosting an AGN for the total galaxy population can be characterized by a universal Eddington ratio (as approximated by LX/M∗) distribution (p(λEdd) ~ λEdd-0.4), which is independent on host mass. Yet consistent with their different AGN fractions, galaxies with different colors appear to also have different p(λEdd) with red galaxies exhibiting more rapid redshift evolution compared with that for green and blue galaxies. Evidence for a steeper power-law distribution of p(λEdd) in red galaxies (p(λEdd) ~ λEdd-0.6) is also presented, though larger samples are needed to confirm. These results suggest that the AGN accretion or the growth of supermassive black holes is related to their host properties, and may also influence their hosts in a different mode dependent on the host color
NNLO QCD corrections to event orientation in e+e- annihilation

We present a new implementation of the NNLO QCD corrections to three-jet
final states and related event-shape observables in electron--positron
annihilation. Our implementation is based on the antenna subtraction method,
and is performed in the NNLOJET framework. The calculation improves upon
earlier results by taking into account the full kinematical information on the
initial state momenta, thereby allowing the event orientation to be computed to
NNLO accuracy. We find the event-orientation distributions at LEP and SLC to be
very robust under higher order QCD corrections
Predicting microbial water quality with models : over-arching questions for managing risk in agricultural catchments

The application of models to predict concentrations of faecal indicator organisms (FIOs) in environmental systems plays an important role for guiding decision-making associated with the management of microbial water quality. In recent years there has been an increasing demand by policy-makers for models to help inform FIO dynamics in order to prioritise efforts for environmental and human-health protection. However, given the limited evidence-base on which FIO models are built relative to other agricultural pollutants (e.g. nutrients) it is imperative that the end-user expectations of FIO models are appropriately managed. In response, this commentary highlights four over-arching questions associated with: (i) model purpose; (ii) modelling approach; (iii) data availability; and (iv) model application, that must be considered as part of good practice prior to the deployment of any modelling approach to predict FIO behaviour in catchment systems. A series of short and longer-term research priorities are proposed in response to these questions in order to promote better model deployment in the field of catchment microbial dynamics
Geometrical tests of cosmological models. II.Calibration of rotational widths and disc scaling relations

This is the second in a series of three papers dedicated to a new technique to select galaxies that can act as standard rods and standard candles in order to perform geometrical tests on large samples of high redshift galaxies to constrain different cosmological parameters. The goals of this paper are (1) to compare different rotation indicators in order to understand the relation between rotation\ud
velocities extracted from observations of the Hαλ6563 Å line and the [OII]λ3727 Å line; and (2) to determine the scaling relations between physical size, surface brightness and magnitude of disc galaxies and their rotation velocity using the SFI++, a large catalog of nearby galaxies observed at I-band. A good correlation is observed between the rotation curve-derived velocities of the Hα and [OII]\ud
observations, as well as between those calculated from velocity histograms, justifying the direct comparison of velocities measuredfrom Hα rotation curves in nearby galaxies and from [OII] line widths at higher redshifts. To provide calibration for the geometrical tests, we give expressions for the different scaling relations between properties of galaxies (size, surface brightness, magnitude) and their rotation speeds. We use Malmquist bias-corrected distances from the SFI++ template Tully-Fisher relation to generate a sizerotation velocity relation with unprecedentedly small scatter. We show how the best size-rotation velocity relation is derived when\ud
size is estimated not from disc scale lengths but from the isophotal diameter r23.5, once these have been corrected for inclination and extinction effects
Charged particle transverse momentum spectra in pp collisions at √s = 0.9 and 7 TeV

The charged particle transverse momentum (pT) spectra are presented for pp collisions at sqrt(s)=0.9 and 7 TeV. The data samples were collected with the CMS detector at the LHC and correspond to integrated luminosities of 231 inverse microbarns and 2.96 inverse picobarns, respectively. Calorimeter-based high-transverse-energy triggers are employed to enhance the statistical reach of the high-pT measurements. The results are compared with both leading-order QCD and with an empirical scaling of measurements at different collision energies using the scaling variable xT = 2 pT/sqrt(s) over the pT range up to 200 GeV/c. Using a combination of xT scaling and direct interpolation at fixed pT, a reference transverse momentum spectrum at sqrt(s)=2.76 TeV is constructed, which can be used for studying high-pT particle suppression in the dense QCD medium produced in heavy-ion collisions at that centre-of-mass energy
Myoblasts inhibit prostate cancer growth by paracrine secretion of TNF alpha

PURPOSE: Myoblasts are capable of forming muscle fibers after transplantation and are therefore envisioned as a treatment for urinary incontinence after radical prostatectomy. However, the safety of this treatment and the interaction of myoblasts with remaining neighboring cancerare unknown. We investigated the interactions between myoblasts and prostate carcinoma cellsin vitro and in vivo. MATERIALS AND METHODS: Myoblasts isolated fromrectus abdominis were used in a series of co-culture experiments with prostate cancer cells and subcutaneously co-injected in vivo. Cell proliferation, cell cycle arrest and apoptosis of cancers in co-culture with myoblasts were assessed. Tumor volume and metastasis formation were evaluated in a mouse model. Tissue specific markers were assessed by immunohistochemistry, FACS analyses, Western blot and RT-qPCR. RESULTS: In this study we have demonstrated that myoblasts, in proximity to tumor, provide paracrine TNFα to their microenvironment, decreasing tumor growth of all prostate cancer cell lines examined. Co-culture experiments showed induction of cell cycle arrest, tumor death by apoptosis and increased differentiation of myoblasts. This effect was largely blocked by TNFα inhibition. The same outcome was demonstrated in a mouse model, where co-injected human myoblasts also inhibited tumor growth and metastasis formation of all prostate cancer cell lines evaluated. CONCLUSIONS: Myoblasts restrict prostate cancer growth and limit metastasis formation by paracrine TNFα secretion in vitro and in vivo
Pure-carbon ring transistor: Role of topology and structure

We report results on the rectification properties of a carbon nanotube (CNT) ring transistor, contacted by CNT leads, whose novel features have been recently communicated by H. Watanabe, C. Manabe, T.  Shigematsu, and M. Shimizu [Appl. Phys. Lett. $\lt$B>78$\lt$/B>, 2928 (2001)]. This letter contains results which are validated by the experimental observations.  Moreover, we report on additional features of the transmission of this ring device which are associated with the possibility of breaking the lead inversion symmetry. The linear conductance displays a chessboardlike behavior alternated with anomalous zero lines which should be directly observable in experiments. We are also able to discriminate the structural properties showing up in our results (quasione-dimensional confinement) from pure topological effects (ring configuration), thus helping to gain physical intuition on the rich ring phenomenology
The impact of science and technology parks on firms´ product innovation: empirical evidence from Spain

Science and Technology Parks (STP) are one of the most important and extensive innovation policy initiatives introduced in recent years. This work evaluates the impact of STP on firm product innovation in the Spanish context. Spain is less developed than most of the advanced countries, and regional and national governments are prioritizing STP initiatives. The large firm sample for our study is from the   Spanish Technological Innovation Survey, provided by the National Statistical Institute. We focus on average treatment effects for firms located in 22 Spanish STP. Our results show that Spanish STP have a strong and positive impact on the probability and amount of product innovation achieved by STP located firms. These results hold for different assumptions about the mechanisms underlying location in a STP.

Four-lepton production in proton–proton collisions, $pp→(Z/γ⁎)(Z/γ⁎)→ℓ^+ℓ^−ℓ'^+ℓ'^−$, where $ℓ,ℓ′=e$ or $μ$, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 2.6 $fb^{-1}$. The ZZ production cross section, $σ(pp→ZZ)=14.6^{+1.9}_{-1.8}(stat)^{+0.5}_{−0.3}(syst)±0.2(theo)±0.4(lumi)pb$, is measured for events with two opposite-sign, same-flavor lepton pairs produced in the mass region $60<m_{ℓ^+ℓ^−},m_{ℓ'^+ℓ'^−}<120GeV$. The Z boson branching fraction to four leptons is measured to be $\mathcal{B}(Z→ℓ^+ℓ^−ℓ'^+ℓ'^−)=4.9^{+0.8}_{−0.7} (stat)^{+0.3}_{−0.2} (syst)+0.2−0.1(theo)±0.1(lumi)×10^{−6}$ for the four-lepton invariant mass in the range $80<m_{ℓ^+ℓ^−ℓ'^+ℓ'^−}<100GeV$ and dilepton mass $m_{ℓ^+ℓ^-}>4GeV$ for all opposite-sign, same-flavor lepton pairs. The results are in agreement with standard model predictions
Generation and characterization of T40/A5754 interfaces with lasers

Laser-induced reactive wetting and brazing of T40 titanium with A5754 aluminum alloy with 1.5 mm thickness was carried out in lap-joint configuration, with or without the use of Al5Si filler wire. A 2.4 mm diameter laser spot was positioned on the aluminum side to provoke spreading and wetting of the lower titanium sheet, with relatively low scanning speeds (0.1 to 0.6 m/min). Process conditions did not play a very significant role on mechanical strengths, which were shown to reach 250-300 N/mm on a large range of laser power and scanning speeds. In all cases considered, the fracture during tensile testing occurred next to the TiAl3 interface, but in the aluminum fusion zone. In a second step, we have investigated the interfacial resistance with the LASAT bond strength tester, based upon the generation and propagation of laser-induced shock waves. This allowed us estimating a uniaxial bond strength of 0.68 GPa for the T40/A5754 interface under dynamic loading conditions.Projet Carnot Attil
Measurement of the pseudorapidity and transverse momentum dependence of the elliptic flow of charged particles in lead-lead collisions at root s(NN)=2.76 TeV with the ATLAS detecto

This Letter describes the measurement of elliptic flow of charged particles in lead–lead collisions at View the MathML sourcesNN=2.76 TeV using the ATLAS detector at the Large Hadron Collider (LHC). The results are based on an integrated luminosity of approximately 7 μb−1. Elliptic flow is measured over a wide region in pseudorapidity, |η|<2.5|η|<2.5, and over a broad range in transverse momentum, 0.5<pT<20 GeV0.5<pT<20 GeV. The elliptic flow parameter v2v2 is obtained by correlating individual tracks with the event plane measured using energy deposited in the forward calorimeters. As a function of transverse momentum, v2(pT)v2(pT) reaches a maximum at pTpT of about 3 GeV, then decreases and becomes weakly dependent on pTpT above 7–8 GeV. Over the measured pseudorapidity region, v2v2 is found to be only weakly dependent on η, with less variation than observed at lower beam energies. The results are discussed in the context of previous measurements at lower collision energies, as well as recent results from the LHC.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; ARTEMIS, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNAS, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT, Greece; ISF, MINERVA, GIF, DIP and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW, Poland; GRICES and FCT, Portugal; MERYS (MECTS), Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MVZT, Slovenia; DST/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America.info:eu-repo/semantics/publishedVersio
Measurement of b-hadron pair production with the ATLAS detector in proton-proton collisions at s√=8 TeV

A measurement of b-hadron pair production is presented, based on a data set corresponding to an integrated luminosity of 11.4 fb−1 of proton-proton collisions recorded at s√=8 TeV with the ATLAS detector at the LHC. Events are selected in which a b-hadron is reconstructed in a decay channel containing J/ψ → μμ, and a second b-hadron is reconstructed in a decay channel containing a muon. Results are presented in a fiducial volume defined by kinematic requirements on three muons based on those used in the analysis. The fiducial cross section is measured to be 17.7 ± 0.1(stat.) ± 2.0(syst.) nb. A number of normalised differential cross sections are also measured, and compared to predictions from the Pythia8, Herwig++, MadGraph5_aMC@NLO+Pythia8 and Sherpa event generators, providing new constraints on heavy flavour production
Genotype-phenotype correlation in NF1 : evidence for a more severe phenotype associated with missense mutations affecting NF1 codons 844–848

Neurofibromatosis type 1 (NF1), a common genetic disorder with a birth incidence of 1: 2,000-3,000, is characterized by a highly variable clinical presentation. To date, only two clinically relevant intragenic genotype-phenotype correlations have been reported for NF1 missense mutations affecting p. Arg1809 and a single amino acid deletion p.Met922del. Both variants predispose to a distinct mild NF1 phenotype with neither externally visible cutaneous/plexiform neurofibromas nor other tumors. Here, we report 162 individuals (129 unrelated probands and 33 affected relatives) heterozygous for a constitutional missense mutation affecting one of five neighboring NF1 codons-Leu844, Cys845, Ala846, Leu847, and Gly848-located in the cysteine-serine-rich domain (CSRD). Collectively, these recurrent missense mutations affect similar to 0.8% of unrelated NF1 mutation-positive probands in the University of Alabama at Birmingham (UAB) cohort. Major superficial plexiform neurofibromas and symptomatic spinal neurofibromas were more prevalent in these individuals compared with classic NF1-affected cohorts (both p < 0.0001). Nearly half of the individuals had symptomatic or asymptomatic optic pathway gliomas and/or skeletal abnormalities. Additionally, variants in this region seem to confer a high predisposition to develop malignancies compared with the general NF1-affected population (p = 0.0061). Our results demonstrate that these NF1 missense mutations, although located outside the GAP-related domain, may be an important risk factor for a severe presentation. A genotype-phenotype correlation at the NF1 region 844-848 exists and will be valuable in the management and genetic counseling of a significant number of individuals
Anti-acanthamoebic properties of natural and marketed honey in Pakistan

To determine anti-Acanthamoebic activity of natural and marketed honey samples. Natural honey samples were collected directly from the bee hive and marketed honey samples were purchased from the local market in Karachi, Pakistan. Both honey samples were tested for their flavonoid content (quercetin equivalent per g of the extract) and phenolic content (gallic acid equivalent per g). Furthermore, their antioxidant activity was determined by measuring 2,2-diphenyl-1-picrylhydrazyl. Using amoebistatic and amoebicidal assays, the effects of honey samples were tested against growth and viability of Acanthamoeba parasites. Natural honey exhibited potent amoebistatic and amoebicidal effects, in a concentration-dependent manner. Honey-treated A. castellanii showed loss of acanthopodia, following which amoebae detached, rounded up, reduced in size, decreased in cytoplasmic mass and they were observed floating in the culture medium. Importantly, honey-treated amoebae did not revive when inoculated in fresh growth medium, however glycerol-treated amoebae exhibited viable trophozoite and active growth. In contrast, marketed honey samples varied in their efficacy against A. castellanii. The proportion of flavonoid, as determined by quercetin measurements and the proportion of phenolic, as determined by gallic acid measurements was higher in natural honey compared with marketed honey. Similarly, the antioxidant activity, as determined by 2,2-diphenyl-1-picrylhydrazyl scavenging activity was higher in natural honey versus marketed honey.  This study shows that natural honey has anti-Acanthamoebic properties and possesses higher flavonoid, phenolic and antioxidant properties compared with the marketed honey. These findings are of concern to the public, health officials, and to the manufacturers regarding production of honey for medical applications. \ud
