Our motivation is to propose a general approach to attack certain extremal problems for sparse simplicial complexes and the corresponding threshold problems for random complexes. In this paper, we focus on threshold problems. The basic model for random complexes is the Linial-Meshulam model Xk(n, p). By definition, such a complex has n vertices, a complete (k -1)-dimensional skeleton, and every possible k-dimensional simplex is chosen independently with probability p. We show that for every k, t≥ 1, there is a constant C = C(k, t) such that for p≥ C/n, the random complex Xk(n, p) asymptotically almost surely contains K tk (the complete k-dimensional complex on t vertices) as a homological minor. As corollary, the threshold for (topological) embeddability of Xk(n, p) into R2k is at p = θ(1/n). The method can be extended to other models of random complexes (for which the lower skeleta are not necessarily complete) and also to more general Tverberg-type problems, where instead of continuous maps without doubly covered image points (embeddings), we consider maps without qfold covered image points.","lang":"eng"}],"day":"01"},{"citation":{"ista":"Li H, Lin D, Dhonukshe P, Nagawa S, Chen D, Friml J, Scheres B, Guo H, Yang Z. 2011.

The phosphorylation status of PIN proteins, which is directly affected by the PINOID (PID) protein kinase and the PP2A protein phosphatase, is known to regulate the apical-basal polarity of PIN localization in bipolar cells of roots and shoot apices. Here, we provide evidence that the phosphorylation status-mediated PIN polarity switch is widely used to modulate cellular processes in Arabidopsis including multipolar pavement cells (PC) with interdigitated lobes and indentations. The degree of PC interdigitation was greatly reduced either when the FYPP1 gene, which encodes a PP2A called phytochrome-associated serine/threonine protein phosphatase, was knocked out or when the PID gene was overexpressed (35S:PID). These genetic modifications caused PIN1 localization to switch from lobe to indentation regions. The PP2A and PID mediated switching of PIN1 localization is strikingly similar to their regulation of the apical-basal polarity switch of PIN proteins in other cells. Our findings suggest a common mechanism for the regulation of PIN1 polarity formation, a fundamental cellular process that is crucial for pattern formation both at the tissue/organ and cellular levels.","lang":"eng"}],"publication":"Cell Research","issue":"6","year":"2011","page":"970 - 978","_id":"2454","publist_id":"4449","doi":"10.1038/cr.2011.49","intvolume":"        21","extern":1,"type":"journal_article","status":"public","publisher":"Nature Publishing Group","publication_status":"published","date_updated":"2021-01-12T06:57:35Z"},{"publist_id":"4443","doi":"10.1016/j.ceb.2011.09.006","intvolume":"        23","extern":"1","publisher":"Elsevier","type":"journal_article","status":"public","publication_status":"published","date_updated":"2021-01-12T06:57:37Z","abstract":[{"text":"In unicellular and multicellular organisms, cell polarity is essential for a wide range of biological processes.

Moreover, flexible respecification of cell polarities enables plants to adjust their physiology and development to environmental changes.

The origins of this pathophysiology are poorly defined for the generation of pacemaking. After the induction of a parkinsonian state in mice, there was a progressive decline in autonomous GPe pacemaking, which normally serves to desynchronize activity. The loss was attributable to the downregulation of an ion channel that is essential in pacemaking, the hyperpolarization and cyclic nucleotide-gated (HCN) channel. Viral delivery of HCN2 subunits restored pacemaking and reduced burst spiking in GPe neurons. However, the motor disability induced by dopamine (DA) depletion was not reversed, suggesting that the loss of pacemaking was a consequence, rather than a cause, of key network pathophysiology, a conclusion that is consistent with the ability of L-type channel antagonists to attenuate silencing after DA depletion.","lang":"eng"}],"issue":"1","publication":"Nature Neuroscience","date_created":"2018-12-11T11:58:06Z","quality_controlled":0,"author":[{"first_name":"Savio","full_name":"Chan, Savio","last_name":"Chan"},{"full_name":"Glajch, Kelly E","last_name":"Glajch","first_name":"Kelly"},{"last_name":"Gertler","full_name":"Gertler, Tracy S","first_name":"Tracy"},{"last_name":"Guzmán","first_name":"Jaime","full_name":"Guzmán, Jaime N"},{"first_name":"Jeff","last_name":"Mercer","full_name":"Mercer, Jeff N"},{"full_name":"Lewis, Alan S","first_name":"Alan","last_name":"Lewis"},{"first_name":"Alan","last_name":"Goldberg","full_name":"Goldberg, Alan B"},{"first_name":"Tatiana","full_name":"Tkatch, Tatiana","last_name":"Tkatch"},{"full_name":"Ryuichi Shigemoto","last_name":"Shigemoto","first_name":"Ryuichi","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8761-9444"},{"last_name":"Fleming","full_name":"Fleming, Sheila M","first_name":"Sheila"},{"last_name":"Chetkovich","full_name":"Chetkovich, Dane M","first_name":"Dane"},{"full_name":"Osten, Pavel","last_name":"Osten","first_name":"Pavel"},{"last_name":"Kita","full_name":"Kita, Hitoshi","first_name":"Hitoshi"},{"full_name":"Surmeier, James D","last_name":"Surmeier","first_name":"James"}],"date_published":"2011-01-01T00:00:00Z","title":"HCN channelopathy in external globus pallidus neurons in models of Parkinson s disease","citation":{"ista":"Chan S, Glajch K, Gertler T, Guzmán J, Mercer J, Lewis A, Goldberg A, Tkatch T, Shigemoto R, Fleming S, Chetkovich D, Osten P, Kita H, Surmeier J. 2011.

We hypothesized that-similar to glutamatergic synapses-the Ca 2+ transients required to activate nNOS were provided by NMDA receptor activation. Indeed, administration of 5 μm NMDA induced a robust nNOS-dependent cGMP production in GABAergic terminals, selectively in the CA1 and CA3c areas. Furthermore, using preembedding, postembedding, and SDS-digested freeze-fracture replica immunogold labeling, we provided quantitative immunocytochemical evidence that NMDAR subunits GluN1, GluN2A, and GluN2B were present in most somatic GABAergic synapses postsynaptically. These data indicate that NMDARs can modulate hippocampal GABAergic inhibition via NO- cGMP signaling in an activity-dependent manner and that this effect is subregion specific in the mouse hippocampus."}],"_id":"2512","page":"5893 - 5904","year":"2011","doi":"10.1523/JNEUROSCI.5938-10.2011","publist_id":"4389","date_updated":"2021-01-12T06:57:56Z","extern":1,"status":"public","type":"journal_article","publication_status":"published","publisher":"Society for Neuroscience","intvolume":"        31","month":"04","volume":31,"citation":{"ieee":"E.

The Sk2 gene (also known as Kcnn2) encodes two isoforms that differ only in the length of their N-terminal domains. SK2-long (SK2-L) and SK2-short (SK2-S) are coexpressed in CA1 pyramidal neurons and likely form heteromeric channels. In mice lacking SK2-L (SK2-S only mice), SK2-S-containing channels were expressed in the extrasynaptic membrane, but were excluded from the PSD. The SK channel contribution to excitatory postsynaptic potentials was absent in SK2-S only mice and was restored by SK2-L re-expression. Blocking SK channels increased the amount of long-term potentiation induced in area CA1 in slices from wild-type mice but had no effect in slices from SK2-S only mice. Furthermore, SK2-S only mice outperformed wild-type mice in the novel object recognition task. These results indicate that SK2-L directs synaptic SK2-containing channel expression and is important for normal synaptic signaling, plasticity and learning.

Understanding this process is limited by the lack of systematic characterization of epithelial organisation. Here we apply network theory at the scale of individual cells to uncover patterns in cell-to-cell contacts that govern epithelial organisation. We provide an objective characterisation of epithelia using network representation, where cells are nodes and cell contacts are links. The features of individual cells, together with attributes of the cellular network, produce a defining signature that distinguishes epithelia from different organs, species, developmental stages and genetic conditions. The approach permits characterization, quantification and classification of normal and perturbed epithelia, and establishes a framework for understanding molecular mechanisms that underpin the architecture of complex tissues."}],"day":"01","_id":"1723","year":"2011","acknowledgement":"We acknowledge the MRC for funding, M.M.B. acknowledges Darwin College, EMBO YIP and Schlumberger Ltd for support.

Both Dpp concentration and signaling gradients scale with tissue size during development. On average, cells divide when Dpp signaling levels have increased by 50%.

We follow up on this finding, and use a suite of WL convergence maps, obtained from ray-tracing N-body simulations, to study (i) the physical origin of WL peaks with different heights, and (ii) whether the peaks contain information beyond the convergence power spectrum P_ell. In agreement with earlier work, we find that high peaks (with amplitudes >~ 3.5 sigma, where sigma is the r.m.s. of the convergence kappa) are typically dominated by a single massive halo. In contrast, medium-height peaks (~0.5-1.5 sigma) cannot be attributed to a single collapsed dark matter halo, and are instead created by the projection of multiple (typically, 4-8) halos along the line of sight, and by random galaxy shape noise. Nevertheless, these peaks dominate the sensitivity to the cosmological parameters w, sigma_8, and Omega_m. We find that the peak height distribution and its dependence on cosmology differ significantly from predictions in a Gaussian random field. We directly compute the marginalized errors on w, sigma_8, and Omega_m from the N(kappa) + P_ell combination, including redshift tomography with source galaxies at z_s=1 and z_s=2. We find that the N(kappa) + P_ell combination has approximately twice the cosmological sensitivity compared to P_ell alone.

The resulting radiative cooling by HD can lower the gas temperature to that of the cosmic microwave background, T_CMB=2.7(1+z)K, significantly below the temperature of a few 100 K achievable via H_2-cooling alone, and thus reduce the masses of the first generation of stars. Here we consider the suppression of HD-cooling by UV irradiation in the Lyman-Werner (LW) bands. We include photo-dissociation of both H_2 and HD, and explicitly compute the self-shielding and shielding of both molecules by neutral hydrogen as well as the shielding of HD by H_2. We use a simplified dynamical collapse model, and follow the chemical and thermal evolution of the gas, in the presence of a UV background. We find that a LW flux of J_crit = 1e-22 erg/cm^2/sr/s/Hz is able to suppress HD cooling and thus prevent collapsing primordial gas from reaching temperatures below 100 K. The main reason for the lack of HD cooling for J>J_crit is the partial photo-dissociation of H_2, which prevents the gas from reaching sufficiently low temperatures (T<150K) for HD to become the dominant coolant; direct HD photo-dissociation is unimportant except for a narrow range of fluxes and column densities. Since the prevention of HD-cooling requires only partial H_2 photo-dissociation, the critical flux J_crit is modest, and is below the UV background required to reionize the universe at redshift z=10-20. We conclude that HD-cooling can reduce the masses of typical stars only in rare halos forming well before the epoch of reionization.","lang":"eng"}],"issue":"4","publication":"Monthly Notices of the Royal Astronomical Society","author":[{"full_name":"Wolcott-Green, J.","first_name":"J.","last_name":"Wolcott-Green"},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman","full_name":"Haiman, Zoltán","first_name":"Zoltán"}],"title":"Suppression of HD cooling in protogalactic gas clouds by Lyman-Werner radiation","main_file_link":[{"url":"https://doi.org/10.1111/j.1365-2966.2010.18080.x","open_access":"1"}]},{"title":"Cosmology with standard sirens: The importance of the shape of the lensing magnification distribution","main_file_link":[{"url":"https://doi.org/10.1111/j.1365-2966.2010.17607.x","open_access":"1"}],"author":[{"last_name":"Shang","full_name":"Shang, Cien","first_name":"Cien"},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","first_name":"Zoltán","last_name":"Haiman"}],"oa_version":"Published Version","day":"21","abstract":[{"text":"The gravitational waves (GWs) emitted by inspiralling binary black holes, expected to be detected by the Laser Interferometer Space Antenna (LISA), could be used to determine the luminosity distance to these sources with the unprecedented precision of ≲1 per cent. We study cosmological parameter constraints from such standard sirens, in the presence of gravitational lensing by large-scale structure. Lensing introduces magnification with a probability distribution function (PDF) whose shape has significant skewness and kurtosis, and depends on cosmological parameters. We use Monte Carlo simulations to generate mock samples of standard sirens, including a small intrinsic scatter, as well as the additional, larger scatter from lensing, in their inferred distances. We derive constraints on cosmological parameters, by simultaneously fitting the mean and the distribution of the residuals on the distance versus redshift (dL–z) Hubble diagram. We find that for standard sirens at redshift z≈ 1, the sensitivity to a single cosmological parameter, such as the matter density Ωm, or the dark energy equation of state w, is ∼50–80 per cent tighter when the lensing PDF is used, compared to the sensitivity derived from a Gaussian PDF with the same variance. When these two parameters are constrained simultaneously, the non-Gaussian shape yields a further enhanced improvement (by ∼120 per cent), owing to the correlation between the parameters. The sensitivity to the amplitude of the matter power spectrum, σ8 from the cosmological dependence of the PDF alone, however, is ∼20 per cent worse than that from the Gaussian PDF. The improvements for Ωm and w arise purely from the non-Gaussian shape of the lensing PDF and can be attributed specifically to the sharpness of the peak of this PDF (i.e. to a finite kurtosis); the dependence of the PDF on these parameters does not improve constraints relative to those available from the mean dL–z relation. At higher redshifts, the PDF resembles a Gaussian more closely, and the effects of the non-Gaussianities become less prominent. These results highlight the importance of obtaining an accurate and reliable PDF of the lensing convergence, in order to realize the full potential of standard sirens as cosmological probes.","lang":"eng"}],"issue":"1","publication":"Monthly Notices of the Royal Astronomical Society","scopus_import":"1","publication_status":"published","extern":"1","alternative_title":["WL and GW standard sirens"],"date_published":"2011-01-21T00:00:00Z","citation":{"chicago":"Shang, Cien, and Zoltán Haiman. “Cosmology with Standard Sirens: The Importance of the Shape of the Lensing Magnification Distribution.” <i>Monthly Notices of the Royal Astronomical Society</i>.

We perform radiative transfer calculations of LW line photons, post-processing outputs from three-dimensional adaptive mesh refinement (AMR) simulations of haloes with T_vir > 10^4 K at redshifts around z=10. We calculate the optically thick photodissociation rate numerically, including the effects of density, temperature, and velocity gradients in the gas, as well as line overlap and shielding of H_2 by HI, over a large number of sight-lines. In low-density regions (n<10^4 cm^-3) the dissociation rates exceed those obtained using most previous approximations by more than an order of magnitude; the correction is smaller at higher densities. We trace the origin of the deviations primarily to inaccuracies of (i) the most common fitting formula (Draine & Bertoldi 1996) for the suppression of the dissociation rate and (ii) estimates for the effective shielding column density from local properties of the gas. The combined effects of gas temperature and velocity gradients are comparatively less important, typically altering the spherically averaged rate only by a factor of less than two. We present a simple modification to the DB96 fitting formula for the optically thick rate which improves agreement with our numerical results to within approx. 15 per cent, and can be adopted in future simulations. We find that estimates for the effective shielding column can be improved by using the local Sobolev length. Our correction to the H_2 self-shielding reduces the critical LW flux to suppress H_2-cooling in T_vir>10^4 K haloes by an order of magnitude; this increases the number of such haloes in which supermassive (approx. M=10^5 M_sun) black holes may have formed."}],"day":"16","oa_version":"Published Version","alternative_title":["H 2 self-shielding in 3D simulations"],"extern":"1","publication_status":"published","scopus_import":"1"},{"main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.1104.1189"}],"title":"A smoother end to the dark ages","author":[{"last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","full_name":"Haiman, Zoltán"}],"external_id":{"arxiv":["1104.1189"]},"day":"06","abstract":[{"text":"Independent lines of evidence suggest that the first stars, which ended the cosmic dark ages, came in pairs, rather than singly.

In contrast to optical experiments where light is detected using photon counters, microwaves are usually measured with well developed linear amplifiers. This makes measurements of correlation functions - one of the important tools in optics - harder to achieve because they traditionally rely on photon counters and beam splitters. Here, we demonstrate a system where we can prepare on demand single microwave photons in a cavity and detect them at the two outputs of the cavity using linear amplifiers. Together with efficient data processing, this allows us to measure different observables of the cavity photons, including the first-order correlation function. Using these techniques we demonstrate cooling of a thermal background field in the cavity."}],"day":"01","issue":"1"}]
