We show the relationship between the multilocus notation recently presented by Kirkpatrick, Johnson, and Barton (developed from previous work by Barton and Turelli) and the cytonuclear parameterization of Asmussen, Arnold, and Avise and extend this notation to describe associations between cytoplasmic elements and multiple nuclear genes. Under models with sexual symmetry, both nuclear-nuclear and cytonuclear disequilibria are equivalent. They differ, however, in cases involving some type of sexual asymmetry, which is then reflected in the asymmetric inheritance of cytoplasmic markers. An example given is the case of different migration rates in males and females; simulations using 2, 3, 4, or 5 unlinked autosomal markers with a maternally inherited cytoplasmic marker illustrate how nuclear-nuclear and cytonuclear associations can be used to separately estimate female and male migration rates. The general framework developed here allows us to investigate conditions where associations between loci with different modes of inheritance are not equivalent and to use this nonequivalence to test for deviations from simple models of admixture.

Our analysis is an extension of previous works, which make a biologically restrictive assumption that selection against deleterious alleles is stronger than that on the beneficial allele of interest. We show that when selection against deleterious alleles is weak, beneficial alleles that confer a selective advantage that is small relative to U have greatly reduced probabilities of fixation. We discuss the consequences of this effect for the distribution of effects of alleles fixed during adaptation. We show that a selective sweep will increase the fixation probabilities of other beneficial mutations arising during some short interval afterward. We use the calculated fixation probabilities to estimate the expected rate of fitness improvement in an asexual population when beneficial alleles arise continually at some low rate proportional to U. We estimate the rate of mutation that is optimal in the sense that it maximizes this rate of fitness improvement. Again, this analysis relaxes the assumption made previously that selection against deleterious alleles is stronger than on beneficial alleles.

What kind of QTL do we expect to find and what can our observations of QTL tell us about how organisms evolve? The key to understanding the evolutionary significance of QTL is to understand the nature of inherited variation, not in the immediate mechanistic sense of how genes influence phenotype, but, rather, to know what evolutionary forces maintain genetic variability.","lang":"eng"}],"volume":3,"month":"01","year":"2002","publication_status":"published","pmid":1,"page":"11 - 21","author":[{"last_name":"Barton","first_name":"Nicholas H","orcid":"0000-0002-8548-5240","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","full_name":"Barton, Nicholas H"},{"full_name":"Keightley, Peter","first_name":"Peter","last_name":"Keightley"}],"doi":"10.1038/nrg700","publisher":"Nature Publishing Group","extern":"1","quality_controlled":"1","_id":"4261","date_published":"2002-01-01T00:00:00Z","day":"01","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","title":"Understanding quantitative genetic variation","article_processing_charge":"No","publication_identifier":{"issn":["1471-0056"]}},{"user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","title":"Extending the coalescent to multilocus systems: the case of balancing selection","day":"23","article_processing_charge":"No","publication_identifier":{"issn":["0016-6723"]},"extern":"1","acknowledgement":"We thank B.

If selection maintains genetic backgrounds at constant frequency then neutral diversity is enhanced. By contrast, if background frequencies fluctuate then diversity is reduced. Provided that the population size of each background is large enough, these effects can be described by the structured coalescent process. Almost all the extant results based on the coalescent deal with a single selected locus. Yet we know that very large numbers of genes are under selection and that any substantial effects are likely to be due to the cumulative effects of many loci. Here, we set up a general framework for the extension of the coalescent to multilocus scenarios and we use it to study the simplest model, where strong balancing selection acting on a set of n loci maintains 2n backgrounds at constant frequencies and at linkage equilibrium. Analytical results show that the expected linked neutral diversity increases exponentially with the number of selected loci and can become extremely large. However, simulation results reveal that the structured coalescent approach breaks down when the number of backgrounds approaches the population size, because of stochastic fluctuations in background frequencies. A new method is needed to extend the structured coalescent to cases with large numbers of backgrounds.","lang":"eng"}],"language":[{"iso":"eng"}],"article_type":"original","citation":{"apa":"Barton, N.

The polymer sub-units are held together in a parallel orientation, forming straight long chains of about 500 nm in width, along which TiO2 spherical particles of about 20-25 nm in diameter are distributed. The polymer chains separated by the titania particles are arranged in a three-dimensional, mechanically stable network, that creates free space and voids into which the iodide/triodide anions can easily migrate. All solid-state dye-sensitized solar cells fabricated using this composite electrolyte present high efficiencies (typical maximum incident photon to current efficiency (IPCE) as high as 40% at 520 nm and overall conversion efficiency (η) of 0.96% (Voc = 0.67 V, Jsc = 2.050 mA/cm2, FF = 39%) under direct solar irradiation. Further improvement of the photovoltaic performance is expected by optimization of the electrolyte parameters and of the cell assembly."}],"status":"public","date_created":"2018-12-11T11:53:44Z","publication":"Journal of Photochemistry and Photobiology A: Chemistry","oa_version":"None","publist_id":"5387","type":"journal_article","publisher":"Elsevier","acknowledgement":"Financial support from NCSR “Demokritos” (Dimoerevna 598 project), Empeirikeion Foundation and General Secretariat for Research and Technology of Greece (EPET II, Greece–France and Greece–Czech Republic bilateral collaboration projects) is also greatly acknowledged.

An alternative interpretation is that these quasars are powered by less massive BHs, but their fluxes are strongly magnified through gravitational lensing by intervening galaxies. Here we analyze the flux distribution of the Ly alpha emission of the quasar with the highest known redshift, SDSS 1030+0524, at z=6.28. We show that this object could not have been magnified by lensing by more than a factor of five. The constraint arises from the large observed size, 30 (comoving) Mpc, of the ionized region around this quasar, and relies crucially only on the assumption that the quasar is embedded in a largely neutral IGM. Based on the line/continuum ratio of SDSS 1030+0524, we argue further that this quasar also cannot be beamed by a significant factor. We conclude that the minimum mass for its resident BH is 4 x 10^8 Msun (for magnification by a factor of five); if the mass is this low, then the quasars had to switch on prior to redshift z=9.\r\nFrom the size of the ionized region, we are also able to place an absolute lower bound on the age of this quasar at t > 2 x 10^7 years.","lang":"eng"}],"status":"public","scopus_import":"1","publication":"The Astrophysical Journal","oa_version":"Published Version","date_created":"2024-09-06T09:11:03Z","main_file_link":[{"url":"https://doi.org/10.1086/342610","open_access":"1"}],"type":"journal_article","article_type":"original","citation":{"chicago":"Haiman, Zoltán, and Renyue Cen. “A Constraint on the Gravitational Lensing Magnification and Age of the Redshift z = 6.28 Quasar SDSS 1030+0524.” <i>The Astrophysical Journal</i>.

We use a semianalytic model to study the scientific yield of combining SZE data with X-ray and optical follow-up observations. If clusters at a given redshift z0 can be identified with virialized, spherical halos, they populate a well-defined \"fundamental plane\" (FP) in the parameter space of the three observables virial temperature (T), total Sunyaev-Zeldovich flux decrement (ΔSν), and angular size (θ). The location and orientation of the FP, as well as its redshift evolution, are sensitive to both the internal evolution of clusters and to the underlying cosmological parameters. We show that if clusters are not standard candles (e.g., because of feedback or energy injection), then this can be inferred from the FP. Likewise, we study the dependence of the FP on the cosmological parameters h, σ8, and Ω0, and quantify future constraints on these parameters. We also show that in the absence of any nongravitational effects, the scatter in the (ΔSν,T)-plane is significantly smaller than in either the (θ,T) or the (θ,ΔSν) planes. As a result, the ΔSν-T relation can be an exceptionally sensitive probe of both cluster physics and cosmological parameters. A comparison of the amount of scatter in these three scaling relations will test the origin (cosmological vs. stochastic) of the scatter.","lang":"eng"}],"intvolume":"       581","date_updated":"2024-09-26T14:09:02Z"},{"publication":"The Astrophysical Journal","scopus_import":"1","date_created":"2024-09-06T09:34:46Z","oa_version":"Published Version","type":"journal_article","main_file_link":[{"url":"https://doi.org/10.1086/343101","open_access":"1"}],"abstract":[{"lang":"eng","text":"For a source of Lyα radiation embedded in a neutral intergalactic medium (IGM) prior to the reionization epoch, the Lyα emission line is strongly suppressed by the intervening IGM. The damping wing of the so-called Gunn-Peterson trough can extend to the red side of the emission line and erase a significant fraction of the total line flux. However, the transmitted fraction increases with the size of the local cosmological H II region surrounding the source, and therefore with the ionizing luminosity and age of the source. Motivated by the recent discovery of a Lyα-emitting galaxy at a redshift z = 6.56 (Hu et al.), possibly prior to the reionization of the IGM, we revisit the effects of a neutral IGM on the Lyα emission line. We show that for faint sources with little or even no ionizing continuum, a sufficiently broad (Δv ≳ 300 km s^-1) emission line can still remain observable. In particular, the line detected by Hu et al. is consistent with a source embedded in a neutral IGM. We provide characterizations of the asymmetry and total transmitted flux of the Lyα line as functions of the ionizing emissivity of its source.

However, the efficiency of H2 formation and cooling in these halos may have been severely limited by feedback processes. In this paper we investigate the radiative cooling and collapse of halos with virial temperatures Tvir > 10^4 K, i.e., those that can cool in the absence of H2 via neutral atomic lines. The evolution of these halos differs from their less massive counterparts. Efficient atomic line radiation allows rapid cooling to ~8000 K; subsequently the gas can contract nearly isothermally at this temperature. In the absence of H2 molecules, the gas would likely settle into a locally stable disk, and only disks with unusually low spin would be unstable. However, we find that the initial atomic line cooling leaves a large, out-of-equilibrium residual free electron fraction. This allows the molecular fraction to build up to a universal value of x ≈ 10^-3, almost independently of initial density and temperature. We show that this is a nonequilibrium freeze-out value that can be understood in terms of timescale arguments. Unlike in less massive halos, H2 formation and cooling is largely impervious to feedback from external UV fields, due to the high initial densities achieved by atomic cooling. The newly formed molecules cool the gas further to ~100 K and allow the gas to fragment on scales of a few times 100 M☉. We investigate the importance of various feedback effects such as H2 photodissociation from internal UV fields and radiation pressure due to Lyα photon trapping, which are likely to regulate the efficiency of star formation."}],"intvolume":"       569","date_updated":"2024-09-30T12:04:29Z"},{"page":"63-72","author":[{"last_name":"Comerford","first_name":"Julia M.","full_name":"Comerford, Julia M."},{"orcid":"0000-0003-3633-5403","first_name":"Zoltán","last_name":"Haiman","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"first_name":"Joop","last_name":"Schaye","full_name":"Schaye, Joop"}],"month":"11","volume":580,"publication_status":"published","year":"2002","citation":{"chicago":"Comerford, Julia M., Zoltán Haiman, and Joop Schaye. “Constraining the Redshift z ~ 6 Quasar Luminosity Function Using Gravitational Lensing.” <i>The Astrophysical Journal</i>.

Here we compute the probability that the fluxes of the quasars are strongly amplified by gravitational lensing and therefore the likelihood that the black hole masses are overestimated when they are inferred assuming Eddington luminosities. The poorly constrained shape of the intrinsic quasar luminosity function (LF) at redshift ~6 results in a large range of possible lensing probabilities. If the LF is either steep or extends to faint magnitudes, the probability for amplification by a factor μ ≳ 10 (and with only one image detectable by SDSS) can reach essentially 100%. We show that future observations, in particular, of either the current four quasars at the high angular resolution provided by the Hubble Space Telescope or an increased sample of ~20 z ~ 6 quasars at the current angular resolution, should either discover several gravitational lenses or else provide interesting new constraints on the shape of the z ~ 6 quasar LF.","lang":"eng"}],"external_id":{"arxiv":["astro-ph/0206441"]},"status":"public","oa_version":"Preprint","publication":"The Astrophysical Journal","scopus_import":"1","date_created":"2024-09-06T10:29:51Z","type":"journal_article","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.astro-ph/0206441"}],"OA_type":"free access","date_updated":"2024-11-12T09:40:33Z","arxiv":1,"intvolume":"       580","publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"article_processing_charge":"No","day":"20","oa":1,"title":"Constraining the Redshift z ~ 6 quasar luminosity function using gravitational lensing","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"17798","quality_controlled":"1","date_published":"2002-11-20T00:00:00Z","publisher":"American Astronomical Society","doi":"10.1086/343116","extern":"1"},{"OA_type":"free access","date_updated":"2024-11-12T09:51:31Z","intvolume":"       123","article_type":"original","citation":{"apa":"Stoughton, C., Lupton, R.

We present and discuss 23 such objects and consider the implications of their wide range of properties for models of BAL outflows and quasars in general. We have discovered one BAL quasar with a record number of absorption lines. Two other similarly complex objects with many narrow troughs show broad Mg II absorption extending longward of their systemic host galaxy redshifts. This can be explained as absorption of an extended continuum source by the rotation-dominated base of a disk wind. Five other objects have absorption that removes an unprecedented ∼90% of all flux shortward of Mg II. The absorption in one of them has varied across the ultraviolet with an amplitude and rate of change as great as ever seen. This same object may also show broad Hβ absorption. Numerous reddened BAL quasars have been found, including at least one reddened mini-BAL quasar with very strong Fe II emission. The five reddest objects have continuum reddenings of E(B-V) ≃ 0.5, and in two of them we find strong evidence that the reddening curve is even steeper than that of the SMC. We have found at least one object with absorption from Fe III but not Fe II. This may be due to a high column density of moderately high ionization gas, but the Fe III level populations must also be affected by some sort of resonance. Finally, we have found two luminous, probably reddened high-redshift objects that may be BAL quasars whose troughs partially cover different regions of the continuum source as a function of velocity."}],"type":"journal_article","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.astro-ph/0203252","open_access":"1"}],"publication":"The Astrophysical Journal Supplement Series","scopus_import":"1","date_created":"2024-09-06T11:30:40Z","oa_version":"Preprint","OA_type":"free access","arxiv":1,"date_updated":"2024-11-12T10:02:25Z","OA_place":"repository","intvolume":"       141"},{"extern":"1","doi":"10.1086/324401","publisher":"American Astronomical Society","_id":"17803","date_published":"2002-01-10T00:00:00Z","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Connections between the cosmic baryon fraction, the extragalactic ionizing background, and Lyman break galaxies","oa":1,"day":"10","article_processing_charge":"No","publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"OA_place":"repository","intvolume":"       564","arxiv":1,"date_updated":"2024-11-12T10:08:42Z","OA_type":"free access","type":"journal_article","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.astro-ph/0104442","open_access":"1"}],"date_created":"2024-09-06T11:31:53Z","scopus_import":"1","oa_version":"Preprint","publication":"The Astrophysical Journal","status":"public","external_id":{"arxiv":["astro-ph/0104442"]},"abstract":[{"lang":"eng","text":"We reassess constraints on the cosmological baryon density from observations of the mean decrement and power spectrum of the Lyα forest, taking into account uncertainties in all free parameters in the simplest gravitational instability model. The uncertainty is dominated by that of the photoionizing background, but incomplete knowledge of the thermal state of the intergalactic medium also contributes significantly to the error budget. While current estimates of the baryon fraction from the forest do prefer values that are somewhat higher than the big bang nucleosynthesis value of Ωb h2 = 0.02 ± 0.001, the discrepancy is at most about 3 σ. For instance, assuming the highest estimate of the ionizing background, as indicated by recent measurements of a large escape fraction from Lyman break galaxies by Steidel, Pettini, & Adelberger, we find Ωbh2 = 0.045 ± 0.008. A recent measurement of the ionizing background from the proximity effect by Scott et al., on the other hand, implies Ωbh2 = 0.03 ± 0.01. We provide an expression from which future likelihoods for Ωb h2 can be derived as measurements of the ionizing background improve—consistency among constraints from the forest, nucleosynthesis, and the microwave background will provide a powerful test of the gravitational instability model for the forest and for large-scale structure in general. We also develop a formalism that treats lower bounds on the baryon density in a statistical manner, which is appropriate if only a lower bound on the ionizing background is known. Finally, we discuss the implications of the escape fraction measurement for the age, structure, and stellar content of Lyman break galaxies. We show that the observed hard spectrum from Lyman break galaxies requires a very young age (less than about 1 million years) and/or a top-heavy initial mass function. We also build a model in which an extended (non-disk-like) gas distribution allows a large escape fraction."}],"language":[{"iso":"eng"}],"citation":{"chicago":"Hui, Lam, Zoltán Haiman, Matias Zaldarriaga, and Tal Alexander. “Connections between the Cosmic Baryon Fraction, the Extragalactic Ionizing Background, and Lyman Break Galaxies.” <i>The Astrophysical Journal</i>.

In this paper we consider a detector based on the Anger scintillation camera. Incident high-energy gamma quanta, generated due to positron decay, produce scintillation effect in the crystal. As a result, a shower of low energy photons in the visible and UV spectra is emitted. These photons are collected by an array of photo-multipliers (PMTs), optically coupled to the scintillation crystal, and invoke electric impulses in them. The PMT responses are utilized in estimation of the scintillation point coordinates. Our work incorporates side information on the photon incidence angle into the process of position estimation. We use localized, asymptotically optimal, nonlinear estimators, implemented by feedforward and radial basis function (RBF) neural networks. As a byproduct, we get accurate position estimation over the entire area of the detector including the edges. This is difficult to obtain with centroid arithmetic algorithms. We present a comparison of algorithms on a Monte Carlo simulation and discuss the prospects for practical implementation.","lang":"eng"}],"status":"public","oa_version":"None","scopus_import":"1","date_created":"2024-10-15T11:20:54Z","publication":"The 22nd Convention on Electrical and Electronics Engineers in Israel","type":"conference","citation":{"ista":"Bronstein AM, Bronstein MM, Zibulevsky M, Zeevi YY. 2002.
