Methods: Thirty adult subjects were randomly divided into three groups of equal size, and orally received purified water (C group), nicotinic acid (300 mg, NA group) or nicotinamide (300 mg, NM group). Plasma nicotinamide, N 1-methylnicotinamide, homocysteine, betaine and choline levels before and 1.5-h and 3-h post-dosing, plasma normetanephrine and metanephrine concentrations at 3-h post-dosing, and the urinary excretion of N 1-methyl-2-pyridone-5-carboxamide during the test period were examined. Results: The level of 3-h plasma nicotinamide, N 1-methylnicotinamide, homocysteine, the urinary excretion of N 1-methyl-2-pyridone-5-carboxamide and pulse pressure (PP) in the NM group was 221%, 3972%, 61%, 1728% and 21.2% higher than that of the control group (P < 0.01, except homocysteine and PP P < 0.05), while the 3-h plasma betaine, normetanephrine and metanephrine level in the NM group was 24.4%, 9.4% and 11.7% lower (P < 0.05, except betaine P < 0.01), without significant difference in choline levels. Similar but less pronounced changes were observed in the NA group, with a lower level of 3-h plasma N 1-methylnicotinamide (1.90 ± 0.20 μmol/l vs. 3.62 ± 0.27 μmol/l, P < 0.01) and homocysteine (12.85 ± 1.39 μmol/l vs. 18.08 ± 1.02 μmol/l, P < 0.05) but a higher level of betaine (27.44 ± 0.71 μmol/l vs. 23.52 ± 0.61 μmol/l, P < 0.05) than that of the NM group. Conclusion: The degradation of nicotinamide consumes more betaine than that of nicotinic acid at identical doses.

CR7 is a luminous Lyα emitting galaxy at z = 6.6 that consists of three separated UV-continuum components. Our observations reveal several well-separated components of [C II] emission. The two most luminous components in [C II] coincide with the brightest UV components (A and B), blueshifted by »150 km s−1 with respect to the\r\npeak of Lyα emission. Other [C II] components are observed close to UV clumps B and C and are blueshifted by »300 and ≈80 km s−1 with respect to the systemic redshift. We do not detect FIR continuum emission due to dust with a 3σ limiting luminosity LIR T L d 35 K 3.1 10 = <´ 10 ( ) . This allows us to mitigate uncertainties in the dust-corrected SFR and derive SFRs for the three UV clumps A, B, and C of 28, 5, and 7 M yr−1. All clumps have [C II] luminosities consistent within the scatter observed in the local relation between SFR and L[ ] C II , implying that strong Lyα emission does not necessarily anti-correlate with [C II] luminosity. Combining\r\nour measurements with the literature, we show that galaxies with blue UV slopes have weaker [C II] emission at fixed SFR, potentially due to their lower metallicities and/or higher photoionization. Comparison with hydrodynamical simulations suggests that CR7ʼs clumps have metallicities of 0.1 Z Z 0.2 < < . The observed ISM structure of CR7 indicates that we are likely witnessing the build up of a central galaxy in the early universe through complex accretion of satellites.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1709.06569"}],"date_created":"2022-07-07T08:48:04Z","month":"12","title":"ALMA reveals metals yet no dust within multiple components in CR7","article_number":"145","article_type":"original","author":[{"full_name":"Matthee, Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720","orcid":"0000-0003-2871-127X","first_name":"Jorryt J","last_name":"Matthee"},{"full_name":"Sobral, D.","first_name":"D.","last_name":"Sobral"},{"full_name":"Boone, F.","first_name":"F.","last_name":"Boone"},{"first_name":"H.","last_name":"Röttgering","full_name":"Röttgering, H."},{"full_name":"Schaerer, D.","first_name":"D.","last_name":"Schaerer"},{"last_name":"Girard","first_name":"M.","full_name":"Girard, M."},{"last_name":"Pallottini","first_name":"A.","full_name":"Pallottini, A."},{"full_name":"Vallini, L.","last_name":"Vallini","first_name":"L."},{"full_name":"Ferrara, A.","first_name":"A.","last_name":"Ferrara"},{"full_name":"Darvish, B.","last_name":"Darvish","first_name":"B."},{"full_name":"Mobasher, B.","first_name":"B.","last_name":"Mobasher"}],"year":"2017","doi":"10.3847/1538-4357/aa9931","day":"21","scopus_import":"1"},{"publist_id":"6206","language":[{"iso":"eng"}],"has_accepted_license":"1","citation":{"ieee":"E.

The additional accuracy increment is obtained by the parallel convex searches applied to the local scalarizations of the misfit vector.

These galaxies have been selected on their Ly α (73), [O II] (285), H β/[O III] (387) or H α (362) emission line, and have been classified with optical to near-infrared colours. A subsample of 98 sources have reliable redshifts from multiple narrow-band (e.g. [O II]–H α) detections and/or spectroscopy. In this survey paper, we present the observations, selection and catalogues of emitters. We measure number densities of Ly α, [O II], H β/[O III] and H α and confirm strong luminosity evolution in star-forming galaxies from z ∼ 0.4 to ∼5, in agreement with previous results. To demonstrate the usefulness of dual-line emitters, we use the sample of dual [O II]–H α emitters to measure the observed [O II]/H α ratio at z = 1.47. The observed [O II]/H α ratio increases significantly from 0.40 ± 0.01 at z = 0.1 to 0.52 ± 0.05 at z = 1.47, which we attribute to either decreasing dust attenuation with redshift, or due to a bias in the (typically) fibre measurements in the local Universe that only measure the central kpc regions. At the bright end, we find that both the H α and Ly α number densities at z ≈ 2.2 deviate significantly from a Schechter form, following a power law. We show that this is driven entirely by an increasing X-ray/active galactic nucleus fraction with line luminosity, which reaches ≈100 per cent at line luminosities L ≳ 3 × 1044 erg s−1.","lang":"eng"}],"type":"journal_article","oa":1,"keyword":["Space and Planetary Science","Astronomy and Astrophysics galaxies","active","galaxies","evolution","galaxies","high-redshift","galaxies","luminosity function","mass function","galaxies: star formation"],"title":"Boötes-HiZELS: An optical to near-infrared survey of emission-line galaxies at z = 0.4–4.7","month":"10","page":"629-649","scopus_import":"1","day":"01","year":"2017","doi":"10.1093/mnras/stx1569","author":[{"id":"7439a258-f3c0-11ec-9501-9df22fe06720","full_name":"Matthee, Jorryt J","last_name":"Matthee","first_name":"Jorryt J","orcid":"0000-0003-2871-127X"},{"last_name":"Sobral","first_name":"David","full_name":"Sobral, David"},{"full_name":"Best, Philip","last_name":"Best","first_name":"Philip"},{"first_name":"Ian","last_name":"Smail","full_name":"Smail, Ian"},{"first_name":"Fuyan","last_name":"Bian","full_name":"Bian, Fuyan"},{"full_name":"Darvish, Behnam","first_name":"Behnam","last_name":"Darvish"},{"first_name":"Huub","last_name":"Röttgering","full_name":"Röttgering, Huub"},{"full_name":"Fan, Xiaohui","first_name":"Xiaohui","last_name":"Fan"}],"article_type":"original","publisher":"Oxford University Press","publication_status":"published","volume":471,"date_published":"2017-10-01T00:00:00Z","oa_version":"Preprint","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 471","publication":"Monthly Notices of the Royal Astronomical Society","issue":"1","_id":"11561","article_processing_charge":"No","date_updated":"2024-10-14T11:34:07Z","publication_identifier":{"issn":["0035-8711","1365-2966"]},"citation":{"ieee":"J.

We use a custom-built Lyα narrow-band filter at the Isaac Newton Telescope, designed to provide a matched volume coverage to the z = 2.23 Hα HiZELS survey. Here, we present the first results for the COSMOS and UDS fields. Our survey currently reaches a 3σ line flux limit of ∼4 × 10−17 erg s−1 cm−2, and a Lyα luminosity limit of ∼1042.3 erg s−1. We find 188 Lyα emitters over 7.3 × 105 Mpc3, but also find significant numbers of other line-emitting sources corresponding to He II, C III] and C IV emission lines. These sources are important contaminants, and we carefully remove them, unlike most previous studies. We find that the Lyα luminosity function at z = 2.23 is very well described by a Schechter function up to LLy α ≈ 1043 erg s−1 with L∗=1042.59+0.16−0.08 erg s−1, ϕ∗=10−3.09+0.14−0.34 Mpc−3 and α = −1.75 ± 0.25. Above LLy α ≈ 1043 erg s−1, the Lyα luminosity function becomes power-law like, driven by X-ray AGN. We find that Lyα-selected emitters have a high escape fraction of 37 ± 7 per cent, anticorrelated with Lyα luminosity and correlated with Lyα equivalent width. Lyα emitters have ubiquitous large (≈40 kpc) Lyα haloes, ∼2 times larger than their Hα extents. By directly comparing our Lyα and Hα luminosity functions, we find that the global/overall escape fraction of Lyα photons (within a 13 kpc radius) from the full population of star-forming galaxies is 5.1 ± 0.2 per cent at the peak of the star formation history. An extra 3.3 ± 0.3 per cent of Lyα photons likely still escape, but at larger radii."}],"date_created":"2022-07-12T12:04:16Z","oa":1,"keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: evolution","galaxies: haloes","galaxies: high-redshift","galaxies: luminosity function","mass function","galaxies: statistics","cosmology: observations"],"type":"journal_article","month":"04","title":"The CALYMHA survey: Lyα luminosity function and global escape fraction of Lyα photons at z = 2.23","doi":"10.1093/mnras/stw3090","year":"2017","author":[{"full_name":"Sobral, David","last_name":"Sobral","first_name":"David"},{"full_name":"Matthee, Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720","orcid":"0000-0003-2871-127X","first_name":"Jorryt J","last_name":"Matthee"},{"full_name":"Best, Philip","last_name":"Best","first_name":"Philip"},{"full_name":"Stroe, Andra","first_name":"Andra","last_name":"Stroe"},{"last_name":"Röttgering","first_name":"Huub","full_name":"Röttgering, Huub"},{"full_name":"Oteo, Iván","first_name":"Iván","last_name":"Oteo"},{"last_name":"Smail","first_name":"Ian","full_name":"Smail, Ian"},{"last_name":"Morabito","first_name":"Leah","full_name":"Morabito, Leah"},{"full_name":"Paulino-Afonso, Ana","first_name":"Ana","last_name":"Paulino-Afonso"}],"page":"1242-1258","scopus_import":"1","day":"01","article_type":"original","publisher":"Oxford University Press","publication_status":"published","oa_version":"Preprint","volume":466,"date_published":"2017-04-01T00:00:00Z","publication":"Monthly Notices of the Royal Astronomical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 466","acknowledgement":"We thank the reviewer for his/her helpful comments and suggestions that have greatly improved this work.

By exploring the rest-frame Lyman Continuum (LyC) with GALEX/NUV data, we find fesc < 2.8 (6.4) per cent through median (mean) stacking. By combining the Hα luminosity density with intergalactic medium emissivity measurements from absorption studies, we find a globally averaged 〈fesc〉 of 5.9+14.5−4.2 per cent at z = 2.2 if we assume HAEs are the only source of ionizing photons. We find similarly low values of the global 〈fesc〉 at z ≈ 3–5, also ruling out a high 〈fesc〉 at z < 5. These low escape fractions allow us to measure ξion, the number of produced ionizing photons per unit UV luminosity, and investigate how this depends on galaxy properties. We find a typical ξion ≈ 1024.77 ± 0.04 Hz erg−1 for HAEs and ξion ≈ 1025.14 ± 0.09 Hz erg−1 for LAEs. LAEs and low-mass HAEs at z = 2.2 show similar values of ξion as typically assumed in the reionization era, while the typical HAE is three times less ionizing. Due to an increasing ξion with increasing EW(Hα), ξion likely increases with redshift. This evolution alone is fully in line with the observed evolution of ξion between z ≈ 2 and 5, indicating a typical value of ξion ≈ 1025.4 Hz erg−1 in the reionization era.","lang":"eng"}],"date_created":"2022-07-12T12:12:14Z"},{"article_type":"original","scopus_import":"1","page":"2381-2396","day":"01","year":"2017","doi":"10.1093/mnras/stw2884","author":[{"first_name":"Jorryt J","last_name":"Matthee","orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720"},{"last_name":"Schaye","first_name":"Joop","full_name":"Schaye, Joop"},{"full_name":"Crain, Robert A.","last_name":"Crain","first_name":"Robert A."},{"last_name":"Schaller","first_name":"Matthieu","full_name":"Schaller, Matthieu"},{"first_name":"Richard","last_name":"Bower","full_name":"Bower, Richard"},{"full_name":"Theuns, Tom","last_name":"Theuns","first_name":"Tom"}],"title":"The origin of scatter in the stellar mass–halo mass relation of central galaxies in the EAGLE simulation","month":"02","type":"journal_article","oa":1,"keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: evolution","galaxies: formation","galaxies: haloes","cosmology: theory"],"date_created":"2022-07-12T12:25:08Z","main_file_link":[{"url":"https://arxiv.org/abs/1608.08218","open_access":"1"}],"abstract":[{"text":"We use the hydrodynamical EAGLE simulation to study the magnitude and origin of the scatter in the stellar mass–halo mass relation for central galaxies. We separate cause and effect by correlating stellar masses in the baryonic simulation with halo properties in a matched dark matter only (DMO) simulation. The scatter in stellar mass increases with redshift and decreases with halo mass. At z = 0.1, it declines from 0.25 dex at M200, DMO ≈ 1011 M⊙ to 0.12 dex at M200, DMO ≈ 1013 M⊙, but the trend is weak above 1012 M⊙. For M200, DMO < 1012.5 M⊙ up to 0.04 dex of the scatter is due to scatter in the halo concentration. At fixed halo mass, a larger stellar mass corresponds to a more concentrated halo. This is likely because higher concentrations imply earlier formation times and hence more time for accretion and star formation, and/or because feedback is less efficient in haloes with higher binding energies. The maximum circular velocity, Vmax, DMO, and binding energy are therefore more fundamental properties than halo mass, meaning that they are more accurate predictors of stellar mass, and we provide fitting formulae for their relations with stellar mass. However, concentration alone cannot explain the total scatter in the Mstar−M200,DMO relation, and it does not explain the scatter in Mstar–Vmax, DMO. Halo spin, sphericity, triaxiality, substructure and environment are also not responsible for the remaining scatter, which thus could be due to more complex halo properties or non-linear/stochastic baryonic effects.","lang":"eng"}],"status":"public","quality_controlled":"1","arxiv":1,"extern":"1","language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1365-2966"],"issn":["0035-8711"]},"citation":{"chicago":"Matthee, Jorryt J, Joop Schaye, Robert A.

We present the first blind, statistical study of C II], C III] and C IV emitters at z ∼ 0.68, 1.05, 1.53, respectively, uniformly selected down to a flux limit of ∼4 × 10−17 erg s−1 cm−1 through a narrow-band survey covering an area of ∼1.4 deg2 over COSMOS and UDS. We detect 16 C II], 35 C III] and 17 C IV emitters, whose nature we investigate using optical colours as well as Hubble Space Telescope (HST), X-ray, radio and far-infrared data. We find that z ∼ 0.7 C II] emitters are consistent with a mixture of blue (UV slope β = −2.0 ± 0.4) star-forming (SF) galaxies with discy HST structure and AGN with Seyfert-like morphologies. Bright C II] emitters have individual X-ray detections as well as high average black hole accretion rates (BHARs) of ∼0.1 M⊙ yr−1. C III] emitters at z ∼ 1.05 trace a general population of SF galaxies, with β = −0.8 ± 1.1, a variety of optical morphologies, including isolated and interacting galaxies and low BHAR (<0.02 M⊙ yr−1). Our C IV emitters at z ∼ 1.5 are consistent with young, blue quasars (β ∼ −1.9) with point-like optical morphologies, bright X-ray counterparts and large BHAR (0.8 M⊙ yr−1). We also find some surprising C II], C III] and C IV emitters with rest-frame equivalent widths (EWs) that could be as large as 50–100 Å. AGN or spatial offsets between the UV continuum stellar disc and the line-emitting regions may explain the large EW. These bright C II], C III] and C IV emitters are ideal candidates for spectroscopic follow-up to fully unveil their nature.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1703.10169"}],"type":"journal_article","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: active","galaxies: high-redshift","quasars: emission lines","galaxies: star formation","cosmology: observations"],"oa":1,"status":"public","quality_controlled":"1","arxiv":1,"day":"01","scopus_import":"1","page":"2558-2574","author":[{"last_name":"Stroe","first_name":"Andra","full_name":"Stroe, Andra"},{"full_name":"Sobral, David","last_name":"Sobral","first_name":"David"},{"orcid":"0000-0003-2871-127X","last_name":"Matthee","first_name":"Jorryt J","full_name":"Matthee, Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720"},{"full_name":"Calhau, João","first_name":"João","last_name":"Calhau"},{"full_name":"Oteo, Ivan","last_name":"Oteo","first_name":"Ivan"}],"doi":"10.1093/mnras/stx1712","year":"2017","article_type":"original","title":"A 1.4 deg2 blind survey for C II], C III] and C IV at z ∼ 0.7–1.5 – I.

We explore the first blind C II], C III] and C IV survey (z ∼ 0.68, 1.05, 1.53, respectively) presented in Stroe et al. (2017). We derive luminosity functions (LF) and study properties of C II], C III] and C IV line emitters through comparisons to the LFs of H α and Ly α emitters, UV selected star-forming (SF) galaxies and quasars at similar redshifts. The C II] LF at z ∼ 0.68 is equally well described by a Schechter or a power-law LF, characteristic of a mixture of SF and AGN activity. The C III] LF (z ∼ 1.05) is consistent to a scaled down version of the Schechter H α and Ly α LF at their redshift, indicating a SF origin. In stark contrast, the C IV LF at z ∼ 1.53 is well fit by a power-law, quasar-like LF. We find that the brightest UV sources (MUV < −22) will universally have C III] and C IV emission. However, on average, C III] and C IV are not as abundant as H α or Ly α emitters at the same redshift, with cosmic average ratios of ∼0.02–0.06 to H α and ∼0.01–0.1 to intrinsic Ly α. We predict that the C III] and C IV lines can only be truly competitive in confirming high-redshift candidates when the hosts are intrinsically bright and the effective Ly α escape fraction is below 1 per cent. While C III] and C IV were proposed as good tracers of young, relatively low-metallicity galaxies typical of the early Universe, we find that, at least at z ∼ 1.5, C IV is exclusively hosted by AGN/quasars, especially at large line equivalent widths.","lang":"eng"}],"date_created":"2022-07-12T12:54:57Z","oa":1,"keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: active","galaxies: high redshift","galaxies: luminosity function","mass function","quasars: emission lines","star formation","cosmology: observations"],"type":"journal_article","quality_controlled":"1","arxiv":1,"status":"public","year":"2017","doi":"10.1093/mnras/stx1713","author":[{"first_name":"Andra","last_name":"Stroe","full_name":"Stroe, Andra"},{"last_name":"Sobral","first_name":"David","full_name":"Sobral, David"},{"orcid":"0000-0003-2871-127X","last_name":"Matthee","first_name":"Jorryt J","full_name":"Matthee, Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720"},{"first_name":"João","last_name":"Calhau","full_name":"Calhau, João"},{"first_name":"Ivan","last_name":"Oteo","full_name":"Oteo, Ivan"}],"scopus_import":"1","page":"2575-2586","day":"01","article_type":"original","month":"11","title":"A 1.4 deg2 blind survey for C II], C III] and C IV at z ∼ 0.7–1.5 – II.

We confirm two new luminous LAEs at z = 5.676 (SR6) and z = 6.532 (VR7), and also present HST follow-up of both sources. These sources have luminosities LLy α ≈ 3 × 1043 erg s−1, very high rest-frame equivalent widths of EW0 ≳ 200 Å and narrow Ly α lines (200–340 km s−1). VR7 is the most UV-luminous LAE at z > 6.5, with M1500 = −22.5, even brighter in the UV than CR7. Besides Ly α, we do not detect any other rest-frame UV lines in the spectra of SR6 and VR7, and argue that rest-frame UV lines are easier to observe in bright galaxies with low Ly α equivalent widths. We confirm that Ly α line widths increase with Ly α luminosity at z = 5.7, while there are indications that Ly α lines of faint LAEs become broader at z = 6.6, potentially due to reionization. We find a large spread of up to 3 dex in UV luminosity for >L⋆ LAEs, but find that the Ly α luminosity of the brightest LAEs is strongly related to UV luminosity at z = 6.6. Under basic assumptions, we find that several LAEs at z ≈ 6–7 have Ly α escape fractions ≳ 100 per cent, indicating bursty star formation histories, alternative Ly α production mechanisms, or dust attenuating Ly α emission differently than UV emission. Finally, we present a method to compute ξion, the production efficiency of ionizing photons, and find that LAEs at z ≈ 6–7 have high values of log10(ξion/Hz erg−1) ≈ 25.51 ± 0.09 that may alleviate the need for high Lyman-Continuum escape fractions required for reionization."}]},{"issue":"2","_id":"11573","date_updated":"2022-08-19T08:07:31Z","article_processing_charge":"No","citation":{"chicago":"Turner, O.

These measurements constrain the internal dynamics, the intrinsic velocity dispersions (σint) and rotation velocities (VC) of galaxies in the high-redshift Universe. The mean velocity dispersion of the galaxies in our sample is σint=70.8+3.3−3.1kms−1, revealing that the increasing average σint with increasing redshift, reported for z ≲ 2, continues out to z ≃ 3.5. Only 36 ± 8 per cent of our galaxies are rotation-dominated (VC/σint > 1), with the sample average VC/σint value much smaller than at lower redshift. After carefully selecting comparable star-forming samples at multiple epochs, we find that the rotation-dominated fraction evolves with redshift with a z−0.2 dependence. The rotation-dominated KDS galaxies show no clear offset from the local rotation velocity–stellar mass (i.e. VC–M⋆) relation, although a smaller fraction of the galaxies are on the relation due to the increase in the dispersion-dominated fraction. These observations are consistent with a simple equilibrium model picture, in which random motions are boosted in high-redshift galaxies by a combination of the increasing gas fractions, accretion efficiency, specific star formation rate and stellar feedback and which may provide significant pressure support against gravity on the galactic disc scale."}],"main_file_link":[{"url":"https://arxiv.org/abs/1704.06263","open_access":"1"}],"type":"journal_article","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: evolution","galaxies: high-redshift","galaxies: kinematics and dynamics"],"oa":1},{"issue":"1","_id":"1159","date_updated":"2025-04-15T07:48:02Z","article_processing_charge":"No","citation":{"apa":"Steenackers, W., Klíma, P., Quareshy, M., Cesarino, I., Kumpf, R., Corneillie, S., … Vanholme, B.

This regulation is achieved by different mechanisms, including auxin biosynthesis, metabolic conversions, degradation, and transport. Here, we introduce cis-cinnamic acid (c-CA) as a novel and unique addition to a small group of endogenous molecules affecting in planta auxin concentrations. c-CA is the photo-isomerization product of the phenylpropanoid pathway intermediate trans-CA (t-CA). When grown on c-CA-containing medium, an evolutionary diverse set of plant species were shown to exhibit phenotypes characteristic for high auxin levels, including inhibition of primary root growth, induction of root hairs, and promotion of adventitious and lateral rooting. By molecular docking and receptor binding assays, we showed that c-CA itself is neither an auxin nor an anti-auxin, and auxin profiling data revealed that c-CA does not significantly interfere with auxin biosynthesis. Single cell-based auxin accumulation assays showed that c-CA, and not t-CA, is a potent inhibitor of auxin efflux. Auxin signaling reporters detected changes in spatiotemporal distribution of the auxin response along the root of c-CA-treated plants, and long-distance auxin transport assays showed no inhibition of rootward auxin transport. Overall, these results suggest that the phenotypes of c-CA-treated plants are the consequence of a local change in auxin accumulation, induced by the inhibition of auxin efflux. This work reveals a novel mechanism how plants may regulate auxin levels and adds a novel, naturally occurring molecule to the chemical toolbox for the studies of auxin homeostasis.","lang":"eng"}],"type":"journal_article","file":[{"date_created":"2019-11-18T16:12:25Z","content_type":"application/pdf","file_name":"2016_PlantPhysi_Steenackers.pdf","file_size":4109142,"checksum":"fd4d1cfe7ed70e54bb12ae3881f3fb91","file_id":"7040","relation":"main_file","date_updated":"2020-07-14T12:44:36Z","creator":"dernst","access_level":"open_access"}],"oa":1},{"publisher":"Nature Publishing Group","publication_status":"published","oa_version":"Published Version","volume":7,"date_published":"2017-01-06T00:00:00Z","publication":"Scientific Reports","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file_date_updated":"2020-07-14T12:44:36Z","intvolume":" 7","isi":1,"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"article_processing_charge":"No","date_updated":"2025-07-10T11:50:13Z","_id":"1160","external_id":{"isi":["000391269700001"]},"department":[{"_id":"BjHo"}],"publication_identifier":{"issn":["2045-2322"]},"citation":{"ista":"Altmeyer S, Do Y, Lai Y. 2017.

However, when a symmetry-breaking transverse magnetic field is present, all flow states exhibit stimulated, finite two-fold mode. Various bifurcations between steady and unsteady states can occur, corresponding to the transitions between the two-cell and one-cell states. While unsteady, axially oscillating flow states can arise, we also detect the emergence of new unsteady flow states. In particular, we uncover two new states: one contains only the azimuthally oscillating solution in the configuration of the twin-cell flow state, and an-other a rotating flow state. Topologically, these flow states are a limit cycle and a quasiperiodic solution on a two-torus, respectively. Emergence of new flow states in addition to observed ones with classical fluid, indicates that richer but potentially more controllable dynamics in ferrofluidic flows, as such flow states depend on the external magnetic field."}],"date_created":"2018-12-11T11:50:28Z","oa":1,"file":[{"file_name":"IST-2017-743-v1+1_srep40012.pdf","content_type":"application/pdf","date_created":"2018-12-12T10:10:16Z","file_id":"4802","checksum":"694aa70399444570825099c1a7ec91f2","file_size":4546835,"access_level":"open_access","creator":"system","date_updated":"2020-07-14T12:44:36Z","relation":"main_file"}],"type":"journal_article","ddc":["532"],"pubrep_id":"743","month":"01","title":"Dynamics of ferrofluidic flow in the Taylor-Couette system with a small aspect ratio","year":"2017","doi":"10.1038/srep40012","author":[{"last_name":"Altmeyer","first_name":"Sebastian","orcid":"0000-0001-5964-0203","id":"2EE67FDC-F248-11E8-B48F-1D18A9856A87","full_name":"Altmeyer, Sebastian"},{"last_name":"Do","first_name":"Younghae","full_name":"Do, Younghae"},{"full_name":"Lai, Ying","last_name":"Lai","first_name":"Ying"}],"scopus_import":"1","day":"06","article_number":"40012"},{"status":"public","quality_controlled":"1","date_created":"2018-12-11T11:50:29Z","abstract":[{"lang":"eng","text":"Coordinated changes of cell shape are often the result of the excitable, wave-like dynamics of the actin cytoskeleton.

One of the pivotal challenges in this field is the designation of a consistent interpretation framework within which we can describe quantitatively the universal features of those systems. Here we analyze in a detailed manner the principal experimental data and compare them quantitatively with the approach based on a single-band model of strongly correlated electrons supplemented with strong antiferromagnetic (super)exchange interaction (the so-called t−J−U model). The model rationale is provided by estimating its microscopic parameters on the basis of the three-band approach for the Cu-O plane. We use our original full Gutzwiller wave-function solution by going beyond the renormalized mean-field theory (RMFT) in a systematic manner. Our approach reproduces very well the observed hole doping (δ) dependence of the kinetic-energy gain in the superconducting phase, one of the principal non-Bardeen-Cooper-Schrieffer features of the cuprates. The calculated Fermi velocity in the nodal direction is practically δ-independent and its universal value agrees very well with that determined experimentally. Also, a weak doping dependence of the Fermi wave vector leads to an almost constant value of the effective mass in a pure superconducting phase which is both observed in experiment and reproduced within our approach. An assessment of the currently used models (t−J, Hubbard) is carried out and the results of the canonical RMFT as a zeroth-order solution are provided for comparison to illustrate the necessity of the introduced higher-order contributions."}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1606.03247"}],"date_created":"2018-12-11T11:50:29Z","date_updated":"2025-06-04T08:39:41Z","article_processing_charge":"No","_id":"1162","issue":"2","language":[{"iso":"eng"}],"publist_id":"6195","external_id":{"isi":["000391852800006"],"arxiv":["1606.03247"]},"citation":{"chicago":"Spałek, Jozef, Michał Zegrodnik, and Jan Kaczmarczyk. “Universal Properties of High Temperature Superconductors from Real Space Pairing T-J-U Model and Its Quantitative Comparison with Experiment.” Physical Review B - Condensed Matter and Materials Physics.

Because they spread mass agnostically at each step in an iterative manner, they can sometimes spread mass “too aggressively,” thereby failing to find the “right” clusters. We introduce a novel Capacity Releasing Diffusion (CRD) Process, which is both faster and stays more local than the classical spectral diffusion process. As an application, we use our CRD Process to develop an improved local algorithm for graph clustering. Our local graph clustering method can find local clusters in a model of clustering where one begins the CRD Process in a cluster whose vertices are connected better internally than externally by an O(log2n) factor, where n is the number of nodes in the cluster. Thus, our CRD Process is the first local graph clustering algorithm that is not subject to the well-known quadratic Cheeger barrier. Our result requires a certain smoothness condition, which we expect to be an artifact of our analysis. Our empirical evaluation demonstrates improved results, in particular for realistic social graphs where there are moderately good—but not very good—clusters."}],"title":"Capacity releasing diffusion for speed and locality","month":"09","page":"3598-3607","day":"01","year":"2017","author":[{"full_name":"Wang, Di","first_name":"Di","last_name":"Wang"},{"last_name":"Fountoulakis","first_name":"Kimon","full_name":"Fountoulakis, Kimon"},{"orcid":"0000-0002-5008-6530","first_name":"Monika H","last_name":"Henzinger","full_name":"Henzinger, Monika H","id":"540c9bbd-f2de-11ec-812d-d04a5be85630"},{"full_name":"Mahoney, Michael W.","first_name":"Michael W.","last_name":"Mahoney"},{"full_name":"Rao , Satish","first_name":" Satish","last_name":"Rao "}]},{"status":"public","arxiv":1,"quality_controlled":"1","type":"journal_article","oa":1,"date_created":"2022-07-27T11:37:23Z","main_file_link":[{"url":"https://arxiv.org/abs/1512.08147","open_access":"1"}],"abstract":[{"lang":"eng","text":"We study the problem of maintaining a breadth-first spanning tree (BFS tree) in partially dynamic distributed networks modeling a sequence of either failures or additions of communication links (but not both).

This problem originates from computational biology, where we are given a phylogenetic tree over a set of species and a directed graph, the so-called food web, encoding viability constraints between these species. These food webs usually have constant depth. The goal is to select a subset of k species that satisfies the viability constraints and has maximal phylogenetic diversity. As this problem is known to be NP-hard, we investigate approximation algorithms. We present the first constant factor approximation algorithm if the depth is constant. Its approximation ratio is (1−1e√). This algorithm not only applies to phylogenetic trees with viability constraints but for arbitrary monotone submodular set functions with viability constraints. Second, we show that there is no (1−1/e+ϵ)-approximation algorithm for our problem setting (even for additive functions) and that there is no approximation algorithm for a slight extension of this setting.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1611.05753"}],"type":"journal_article","keyword":["Approximation algorithms","Submodular functions","Phylogenetic diversity","Viability constraints"],"oa":1,"title":"Maximizing a submodular function with viability constraints","month":"01","day":"01","scopus_import":"1","page":"152-172","author":[{"last_name":"Dvořák","first_name":"Wolfgang","full_name":"Dvořák, Wolfgang"},{"first_name":"Monika H","last_name":"Henzinger","orcid":"0000-0002-5008-6530","full_name":"Henzinger, Monika H","id":"540c9bbd-f2de-11ec-812d-d04a5be85630"},{"last_name":"Williamson","first_name":"David P.","full_name":"Williamson, David P."}],"year":"2017","doi":"10.1007/s00453-015-0066-y","article_type":"original","publication_status":"published","publisher":"Springer Nature","date_published":"2017-01-01T00:00:00Z","volume":77,"oa_version":"Preprint","intvolume":" 77","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication":"Algorithmica","acknowledgement":"The research leading to these results has received funding from the European Research\r\nCouncil under the European Union’s Seventh Framework Programme (FP/2007-2013)/ERC Grant Agreement No. 340506.","issue":"1","_id":"11676","date_updated":"2024-11-06T12:07:55Z","article_processing_charge":"No","citation":{"ieee":"W.

The use of these models allows one to gain in flexibility by considering the model parameter set split into marginal and dependence parameters. However, this separation also leads to the natural issue of estimating only a subset of all model parameters. In this work, we treat this problem with the application of the (Formula presented.)-optimality to copula models. First, we provide an extension of the corresponding equivalence theory. Then, we analyze a wide range of flexible copula models to highlight the usefulness of (Formula presented.)-optimality in many possible scenarios. Finally, we discuss how the usage of the introduced design criterion also relates to the more general issue of copula selection and optimal design for model discrimination.","lang":"eng"}],"date_created":"2018-12-11T11:50:31Z","quality_controlled":"1","status":"public","corr_author":"1","author":[{"full_name":"Perrone, Elisa","id":"2A5F8724-F248-11E8-B48F-1D18A9856A87","first_name":"Elisa","last_name":"Perrone","orcid":"0000-0003-0370-9835"},{"first_name":"Andreas","last_name":"Rappold","full_name":"Rappold, Andreas"},{"full_name":"Müller, Werner","last_name":"Müller","first_name":"Werner"}],"year":"2017","doi":"10.1007/s10260-016-0375-6","day":"01","page":"403 - 418","scopus_import":"1","month":"08","title":"D inf s optimality in copula models","ddc":["519"],"pubrep_id":"739"}]
