Auxin is directionally transported from cell to cell by the action of specific auxin influx [AUXIN-RESISTANT1 (AUX1)] and efflux [PIN-FORMED (PIN)] transport regulators, whose polar, subcellular localizations are aligned with the direction of the auxin flow. Auxin itself regulates its own transport by modulation of the expression and subcellular localization of the auxin transporters. Increased auxin levels promote the transcription of PIN2 and AUX1 genes as well as stabilize PIN proteins at the plasma membrane, whereas prolonged auxin exposure increases the turnover of PIN proteins and their degradation in the vacuole. In this study, we applied a forward genetic approach, to identify molecular components playing a role in the auxin-mediated degradation. We generated EMS-mutagenized Arabidopsis PIN2::PIN2:GFP, AUX1::AUX1:YFP eir1aux1 populations and designed a screen for mutants with persistently strong fluorescent signals of the tagged PIN2 and AUX1 after prolonged treatment with the synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D). This approach yielded novel auxin degradation mutants defective in trafficking and degradation of PIN2 and AUX1 proteins and established a role for auxin-mediated degradation in plant development.","lang":"eng"}],"article_processing_charge":"No","external_id":{"isi":["000376482300015"]},"doi":"10.1007/s00344-015-9553-2","pubrep_id":"1001","volume":35,"department":[{"_id":"JiFr"}],"publist_id":"5512","ddc":["581"],"has_accepted_license":"1","oa":1,"file":[{"access_level":"open_access","date_updated":"2020-07-14T12:45:08Z","creator":"system","file_size":5637591,"date_created":"2018-12-12T10:08:34Z","file_id":"4695","checksum":"0dc6a300cde6536ceedd2bcdd2060efb","file_name":"IST-2018-1001-v1+1_Zemova_JPlantGrowthRegul_2016_proofs.pdf","content_type":"application/pdf","relation":"main_file"}],"_id":"1641","title":"A forward genetic screen for new regulators of auxin mediated degradation of auxin transport proteins in Arabidopsis thaliana","quality_controlled":"1","intvolume":" 35","corr_author":"1","oa_version":"Preprint","publication_status":"published","year":"2016","date_published":"2016-06-01T00:00:00Z","issue":"2","citation":{"ista":"Zemová R, Zwiewka M, Bielach A, Robert H, Friml J. 2016.

Furthermore, there is a way to set up the hash key hk to make it statistically binding on some arbitrary hidden position i, meaning that: (1) the digest y completely determines the i’th bit (or symbol) of x so that all pre-images of y have the same value in the i’th position, (2) it is computationally infeasible to distinguish the position i on which hk is statistically binding from any other position i’. Lastly, the hash should have a local opening property analogous to Merkle-Tree hashing, meaning that given x and y = H hk (x) it should be possible to create a short proof π that certifies the value of the i’th bit (or symbol) of x without having to provide the entire input x. A similar primitive called a positional accumulator, introduced by Koppula, Lewko and Waters (STOC ’15) further supports dynamic updates of the hashed value. These tools, which are interesting in their own right, also serve as one of the main technical components in several recent works building advanced applications from indistinguishability obfuscation (iO).\r\n\r\nThe prior constructions of SSB hashing and positional accumulators required fully homomorphic encryption (FHE) and iO respectively.

A verification tool like SpaceEx is based on the exploration of a symbolic search space (the region space). As a verification tool, it is typically optimized towards proving the absence of errors. In some settings, e.g., when the verification tool is employed in a feedback-directed design cycle, one would like to have the option to call a version that is optimized towards finding an error trajectory in the region space. A recent approach in this direction is based on guided search. Guided search relies on a cost function that indicates which states are promising to be explored, and preferably explores more promising states first. In this paper, we propose an abstraction-based cost function based on coarse-grained space abstractions for guiding the reachability analysis. For this purpose, a suitable abstraction technique that exploits the flexible granularity of modern reachability analysis algorithms is introduced. The new cost function is an effective extension of pattern database approaches that have been successfully applied in other areas. The approach has been implemented in the SpaceEx model checker. The evaluation shows its practical potential."}],"article_processing_charge":"Yes (via OA deal)","file":[{"access_level":"open_access","date_updated":"2020-07-14T12:45:13Z","creator":"system","file_id":"5146","date_created":"2018-12-12T10:15:26Z","file_size":2296522,"file_name":"IST-2016-457-v1+1_s10009-015-0393-y.pdf","checksum":"31561d7705599a9bd4ea816accc0752e","content_type":"application/pdf","relation":"main_file"}],"_id":"1705","title":"Guided search for hybrid systems based on coarse-grained space abstractions","quality_controlled":"1","intvolume":" 18","department":[{"_id":"ToHe"}],"publist_id":"5431","ddc":["000"],"has_accepted_license":"1","oa":1,"citation":{"mla":"Bogomolov, Sergiy, et al. “Guided Search for Hybrid Systems Based on Coarse-Grained Space Abstractions.” International Journal on Software Tools for Technology Transfer, vol. 18, no. 4, Springer, 2016, pp. 449–67, doi:10.1007/s10009-015-0393-y.","ieee":"S.

We suggest that the growth of SMBHs above a few 10^{10} M_sun is prevented by small-scale accretion physics, independent of the properties of their host galaxies or of cosmology. Growing more massive BHs requires a gas supply rate from galactic scales onto a nuclear region as high as >10^3 M_sun/yr. At such a high accretion rate, most of the gas converts to stars at large radii (~10-100 pc), well before reaching the BH. We adopt a simple model (Thompson et al. 2005) for a star-forming accretion disk, and find that the accretion rate in the sub-pc nuclear region is reduced to the smaller value of at most a few M_sun/yr. This prevents SMBHs from growing above ~10^{11} M_sun in the age of the Universe. Furthermore, once a SMBH reaches a sufficiently high mass, this rate falls below the critical value at which the accretion flow becomes advection dominated. Once this transition occurs, BH feeding can be suppressed by strong outflows and jets from hot gas near the BH. We find that the maximum SMBH mass, given by this transition, is between M_{BH,max} ~ (1-6) * 10^{10} M_sun, depending primarily on the efficiency of angular momentum transfer inside the galactic disk, and not on other properties of the host galaxy."}],"article_processing_charge":"No","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","article_number":"110","language":[{"iso":"eng"}],"scopus_import":"1","volume":828,"external_id":{"arxiv":["1601.02611"]},"doi":"10.3847/0004-637x/828/2/110","oa":1,"main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.1601.02611"}],"extern":"1","intvolume":" 828","quality_controlled":"1","_id":"17618","title":"Is there a maximum mass for black holes in galactic nuclei?","publication_identifier":{"issn":["0004-637X","1538-4357"]},"date_published":"2016-09-12T00:00:00Z","oa_version":"Preprint","publication_status":"published","year":"2016","article_type":"original","author":[{"full_name":"Inayoshi, Kohei","last_name":"Inayoshi","first_name":"Kohei"},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","last_name":"Haiman","first_name":"Zoltán"}],"citation":{"short":"K.

This approach utilises a covariance matrix of emission-line properties obtained from a large, moderate-z (2 ≤ z ≤ 2.5), high signal to noise (S/N > 15) sample of BOSS QSOs. For each QSO, we complete a Monte Carlo Markov Chain fitting of the continuum and emission-line properties and perform a visual quality assessment to construct a large data base of robustly fit spectra. With this data set, we construct a covariance matrix to describe the correlations between the high-ionization emission lines Lyα, C iv, Si iv +O iv] and C iii], and find it to be well approximated by an N-dimensional Gaussian distribution. This covariance matrix characterizes the correlations between the linewidth, peak height and velocity offset from systemic while also allowing for the existence of broad- and narrow-line components for Lyα and C iv. We illustrate how this covariance matrix allows us to statistically characterize the intrinsic Lyα line solely from the observed spectrum redward of 1275 Å. This procedure can be used to reconstruct the intrinsic Lyα line emission profile in cases where Lyα may otherwise be obscured. Applying this reconstruction method to our sample of QSOs, we recovered the Lyα line flux to within 15 per cent of the measured flux at 1205 Å (1220 Å) ∼85 (90) per cent of the time.","lang":"eng"}]},{"intvolume":" 94","quality_controlled":"1","_id":"17626","title":"Cosmology with photometric weak lensing surveys: Constraints with redshift tomography of convergence peaks and moments","publication_identifier":{"issn":["2470-0010","2470-0029"]},"oa":1,"main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.1605.01100"}],"extern":"1","author":[{"last_name":"Petri","first_name":"Andrea","full_name":"Petri, Andrea"},{"full_name":"May, Morgan","last_name":"May","first_name":"Morgan"},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","first_name":"Zoltán","last_name":"Haiman"}],"issue":"6","citation":{"ista":"Petri A, May M, Haiman Z. 2016.

When analyzing galaxy surveys, redshift information has proven to be a valuable addition to angular shear correlations. We forecast parameter constraints on the triplet (Ω𝑚,𝑤,𝜎8) for a LSST-like photometric galaxy survey, using tomography of the shear-shear power spectrum, convergence peak counts and higher convergence moments. We find that redshift tomography with the power spectrum reduces the area of the 1𝜎 confidence interval in (Ω𝑚,𝑤) space by a factor of 8 with respect to the case of the single highest redshift bin. We also find that adding non-Gaussian information from the peak counts and higher-order moments of the convergence field and its spatial derivatives further reduces the constrained area in (Ω𝑚,𝑤) by factors of 3 and 4, respectively. When we add cosmic microwave background parameter priors from Planck to our analysis, tomography improves power spectrum constraints by a factor of 3. Adding moments yields an improvement by an additional factor of 2, and adding both moments and peaks improves by almost a factor of 3 over power spectrum tomography alone.

An accurate estimate of the 𝑁𝑏×𝑁𝑏 feature covariance matrix 𝐂 is essential to obtain accurate parameter confidence intervals. When 𝐂 is measured from a set of simulations, an important question is how large this set should be. To answer this question, we construct different ensembles of 𝑁𝑟 realizations of the shear field, using a common randomization procedure that recycles the outputs from a smaller number 𝑁𝑠≤𝑁𝑟 of independent ray-tracing 𝑁-body simulations. We study parameter confidence intervals as a function of (𝑁𝑠, 𝑁𝑟) in the range 1≤𝑁𝑠≤200 and 1≤𝑁𝑟≲105. Previous work [S. Dodelson and M. D. Schneider, Phys. Rev. D 88, 063537 (2013)] has shown that Gaussian noise in the feature vectors (from which the covariance is estimated) lead, at quadratic order, to an 𝑂(1/𝑁𝑟) degradation of the parameter confidence intervals. Using a variety of lensing features measured in our simulations, including shear-shear power spectra and peak counts, we show that cubic and quartic covariance fluctuations lead to additional 𝑂(1/𝑁2𝑟) error degradation that is not negligible when 𝑁𝑟 is only a factor of few larger than 𝑁𝑏. We study the large 𝑁𝑟 limit, and find that a single, 240 Mpc/ℎ sized 5123-particle 𝑁-body simulation (𝑁𝑠=1) can be repeatedly recycled to produce as many as 𝑁𝑟=few×104 shear maps whose power spectra and high-significance peak counts can be treated as statistically independent. As a result, a small number of simulations (𝑁𝑠=1 or 2) is sufficient to forecast parameter confidence intervals at percent accuracy.","lang":"eng"}],"article_processing_charge":"No","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","external_id":{"arxiv":["1601.06792"]},"doi":"10.1103/physrevd.93.063524","volume":93,"main_file_link":[{"url":" https://doi.org/10.48550/arXiv.1601.06792","open_access":"1"}],"extern":"1","oa":1,"_id":"17628","title":"Sample variance in weak lensing: How many simulations are required?","publication_identifier":{"issn":["2470-0010","2470-0029"]},"intvolume":" 93","quality_controlled":"1","article_type":"original","date_published":"2016-03-24T00:00:00Z","publication_status":"published","oa_version":"Preprint","year":"2016","citation":{"ista":"Petri A, Haiman Z, May M. 2016.

We study the origin of lensing peaks using observational data from the 154 deg2 Canada-France-Hawaii Telescope Lensing Survey. We found that while high peaks (with height κ >3.5 σκ, where σκ is the r.m.s. of the convergence κ) are typically due to one single massive halo of ~1015M⊙, low peaks (κ <~ σκ) are associated with constellations of 2-8 smaller halos (<~1013M⊙). In addition, halos responsible for forming low peaks are found to be significantly offset from the line-of-sight towards the peak center (impact parameter >~ their virial radii), compared with ~0.25 virial radii for halos linked with high peaks, hinting that low peaks are more immune to baryonic processes whose impact is confined to the inner regions of the dark matter halos.

We consider dark matter haloes formed from progenitors that have undergone no star formation as a result of early reionization and photoevaporation caused by a nearby galaxy. Once such a halo reaches ≈109 M⊙, corresponding to the Jeans mass of the photoheated intergalactic medium at z ≈ 7, pristine gas is able to collapse into the halo, potentially producing a massive Pop III starburst. We suggest that this scenario may explain the recent observation of strong He ii 1640 Å line emission in CR 7, which is consistent with ∼107 M⊙ of young Pop III stars. Such a large mass of Pop III stars is unlikely without the photoionization feedback scenario, because star formation is expected to inject metals into haloes above the atomic cooling threshold (∼108 M⊙ at z ≈ 7). We use merger trees to analytically estimate the abundance of observable Pop III galaxies formed through this channel, and find a number density of ≈10−7 Mpc−3 at z = 6.6 (the redshift of CR 7). This is approximately a factor of 10 lower than the density of Ly α emitters as bright as CR 7.","lang":"eng"}],"scopus_import":"1","language":[{"iso":"eng"}],"status":"public","date_created":"2024-09-06T07:32:23Z","type":"journal_article","day":"14","date_updated":"2024-09-24T14:19:51Z","publisher":"Oxford University Press","publication":"Monthly Notices of the Royal Astronomical Society: Letters","page":"L59-L63"},{"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","article_processing_charge":"No","abstract":[{"lang":"eng","text":"We explore the evolution of stellar mass black hole binaries (BHBs) which are formed in the self-gravitating discs of active galactic nuclei (AGN).

For mass ratios above q = 0.04, solutions for the hydrodynamic flow transition from steady, to strongly fluctuating; a narrow annular gap in the surface density around the secondary's orbit changes to a hollow central cavity; and a spatial symmetry is lost, resulting in a lopsided disc. This phase transition is coincident with the mass ratio above which stable orbits do not exist around the L4 and L5 equilibrium points of the R3Bp. Using the disco code, we find that for thin discs, for which a gap or cavity can remain open, the mass ratio of the transition is relatively insensitive to disc viscosity and pressure.

PopIII stars are efficient producers of BBHs and of a gravitational wave background (GWB) in the 10–100 Hz band, and also of ionizing radiation in the early Universe. We quantify the relation between the amplitude of the GWB (Ωgw) and the electron scattering optical depth (τe), produced by PopIII stars, assuming that fesc ≈ 10 per cent of their ionizing radiation escapes into the intergalactic medium. We find that PopIII stars would produce a GWB that is detectable by the future O5 LIGO/Virgo if τe ≳ 0.07, consistent with the recent Planck measurement of τe = 0.055 ± 0.09. Moreover, the spectral index of the background from PopIII BBHs becomes as small as dln Ωgw/dln f ≲ 0.3 at f ≳ 30 Hz, which is significantly flatter than the value ∼2/3 generically produced by lower redshift and less-massive BBHs. A detection of the unique flattening at such low frequencies by the O5 LIGO/Virgo will indicate the existence of a high-chirp mass, high-redshift BBH population, which is consistent with the PopIII origin.

We analysed Lomb–Scargle periodograms and assessed the significance of our findings by modelling each individual quasar's variability as a damped random walk (DRW). We identified 50 quasars with significant periodicity beyond the DRW model, typically with short periods of a few hundred days. We find 33 of these to remain significant after a re-analysis of their periodograms including additional optical data from the intermediate-PTF and the Catalina Real-Time Transient Survey. Assuming that the observed periods correspond to the redshifted orbital periods of SMBHBs, we conclude that our findings are consistent with a population of unequal-mass SMBHBs, with a typical mass ratio as low as q ≡ M2/M1 ≈ 0.01.","lang":"eng"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","language":[{"iso":"eng"}],"scopus_import":"1","volume":463,"doi":"10.1093/mnras/stw1838","oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stw1838"}],"extern":"1","intvolume":" 463","quality_controlled":"1","title":"A population of short-period variable quasars from PTF as supermassive black hole binary candidates","_id":"17672","publication_identifier":{"issn":["0035-8711","1365-2966"]},"date_published":"2016-07-28T00:00:00Z","year":"2016","publication_status":"published","oa_version":"Published Version","article_type":"original","author":[{"last_name":"Charisi","first_name":"M.","full_name":"Charisi, M."},{"full_name":"Bartos, I.","last_name":"Bartos","first_name":"I."},{"first_name":"Zoltán","last_name":"Haiman","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"last_name":"Price-Whelan","first_name":"A.

Assuming that photon trapping limits the luminosity emerging from the central region to L≲LEdd, Inayoshi, Haiman & Ostriker (2016) have shown that an accretion flow settles to a \"hyper-Eddington\" solution, with a steady and isothermal (T≃8000 K) Bondi profile reaching ≳5000 times the Eddington accretion rate M˙Edd≡LEdd/c2. Here we address the possibility that gas accreting with finite angular momentum forms a bright nuclear accretion disc, with a luminosity exceeding the Eddington limit (1≲L/LEdd≲100). Combining our simulations with an analytic model, we find that a transition to steady hyper-Eddington accretion still occurs, as long as the luminosity remains below L/LEdd≲35 (MBH/10^4 M⊙)^3/2(n∞/10^5 cm^−3)(T∞/10^4 K)^−3/2(r⋆/10^14 cm)^−1/2, where n∞ and T∞ are the density and temperature of the ambient gas, and r⋆ is the radius of the photosphere, at which radiation emerges. If the luminosity exceeds this value, accretion becomes episodic. Our results can be accurately recovered in a toy model of an optically thick spherical shell, driven by radiation force into a collapsing medium. When the central source is dimmer than the above critical value, the expansion of the shell is halted and reversed by ram pressure of the collapsing medium, and by shell's weight. Our results imply that rapid, unimpeded hyper-Eddington accretion is possible even if the luminosity of the central source far exceeds the Eddington limit, and can be either steady or strongly episodic.","lang":"eng"}],"doi":"10.1093/mnras/stw1652","volume":461,"page":"4496-4504","publisher":"Oxford University Press","publication":"Monthly Notices of the Royal Astronomical Society","type":"journal_article","day":"08","date_updated":"2024-09-25T10:02:57Z","date_created":"2024-09-06T08:39:53Z","status":"public","article_type":"original","year":"2016","oa_version":"Published Version","publication_status":"published","date_published":"2016-07-08T00:00:00Z","month":"07","issue":"4","citation":{"ista":"Sakurai Y, Inayoshi K, Haiman Z. 2016.

For (i) we use a new intrinsic Ly\\alpha\\ emission line reconstruction method (Greig et al.), sampling a covariance matrix of emission line properties built from a large database of moderate-z QSOs. For (ii), we use the Evolution of 21-cm Structure (EOS; Mesinger et al.) simulations, which span a range of physically-motivated EoR models. We find strong evidence for the presence of damping wing absorption redward of Ly\\alpha\\ (where there is no contamination from the Ly\\alpha\\ forest). Our analysis implies that the EoR is not yet complete by z=7.1, with the volume-weighted IGM neutral fraction constrained to x¯HI=0.40+0.21−0.19 at 1σ (x¯HI=0.40+0.41−0.32 at 2σ). This result is insensitive to the EoR morphology.
