Known results easily imply the polynomiality of EMBEDk→2 (k = 1; 2; the case k = 1, d = 2 is graph planarity) and of EMBEDk→2k for all k ≥ 3. We show that the celebrated result of Novikov on the algorithmic unsolvability of recognizing the 5-sphere implies that EMBEDd→d and EMBED (d-1)→d are undecidable for each d ≥ 5. Our main result is the NP-hardness of EMBED2→4 and, more generally, of EMBED k→d for all k; d with d ≥ 4 and d ≥ k ≥ (2d - 2)/3. These dimensions fall outside the metastable range of a theorem of Haefliger and Weber, which characterizes embeddability using the deleted product obstruction. Our reductions are based on examples, due to Segal, Spież, Freedman, Krushkal, Teichner, and Skopenkov, showing that outside the metastable range the deleted product obstruction is not sufficient to characterize embeddability.

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."}],"date_published":"2011-01-01T00:00:00Z","page":"351 - 360","publication_status":"published","day":"01"},{"intvolume":"        21","issue":"6","extern":1,"citation":{"ieee":"H.

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."}],"day":"01","date_published":"2011-06-01T00:00:00Z","publication_status":"published","page":"970 - 978","_id":"2454","oa":1,"author":[{"first_name":"Hongjiang","full_name":"Hongjiang Li","last_name":"Li","id":"33CA54A6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5039-9660"},{"first_name":"Deshu","full_name":"Lin, Deshu","last_name":"Lin"},{"first_name":"Pankaj","full_name":"Dhonukshe, Pankaj B","last_name":"Dhonukshe"},{"last_name":"Nagawa","full_name":"Nagawa, Shingo","first_name":"Shingo"},{"last_name":"Chen","first_name":"Dandan","full_name":"Chen, Dandan"},{"first_name":"Jirí","full_name":"Jirí Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml","orcid":"0000-0002-8302-7596"},{"last_name":"Scheres","full_name":"Scheres, Ben","first_name":"Ben"},{"last_name":"Guo","first_name":"Hongwei","full_name":"Guo, Hongwei"},{"first_name":"Zhenbiao","full_name":"Yang, Zhenbiao","last_name":"Yang"}]},{"_id":"2460","author":[{"first_name":"Jan","full_name":"Dettmer, Jan","last_name":"Dettmer"},{"orcid":"0000-0002-8302-7596","last_name":"Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jirí","full_name":"Friml, Jirí"}],"abstract":[{"text":"In unicellular and multicellular organisms, cell polarity is essential for a wide range of biological processes.

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.

Here, we provide evidence that the retrograde nitric oxide (NO)- cGMP cascade triggered by NMDA receptor (NMDAR) activation plays a role in the control of hippocampal GABAergic transmission in mice. GABAergic synapses express neuronal nitric oxide synthase (nNOS) postsynaptically and NO receptors (NO-sensitive guanylyl cyclase) in the presynaptic terminals. 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.","lang":"eng"}],"publication_status":"published","page":"5893 - 5904","date_published":"2011-04-20T00:00:00Z","day":"20","publisher":"Society for Neuroscience","date_updated":"2021-01-12T06:57:56Z","year":"2011","doi":"10.1523/JNEUROSCI.5938-10.2011","type":"journal_article","status":"public","quality_controlled":0,"publist_id":"4389","month":"04","volume":31,"title":"NMDA receptors in hippocampal GABAergic synapses and their role in nitric oxide signaling","publication":"Journal of Neuroscience","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.

Considered are N×N symmetric, Hermitian, or quaternion self-dual random matrices with independent identically distributed entries (Wigner matrices), where the probability distribution of each matrix element is given by a measure v with zero expectation and with subexponential decay. The main result is that the correlation functions of the local eigenvalue statistics in the bulk of the spectrum coincide with those of the Gaussian Orthogonal Ensemble (GOE), the Gaussian Unitary Ensemble (GUE), and the Gaussian Symplectic Ensemble (GSE), respectively, in the limit as N → ∞. This approach is based on a study of the Dyson Brownian motion via a related new dynamics, the local relaxation flow. As a main input, it is established that the density of the eigenvalues converges to the Wigner semicircle law, and this holds even down to the smallest possible scale. Moreover, it is shown that the eigenvectors are completely delocalized. These results hold even without the condition that the matrix elements are identically distributed: only independence is used. In fact, for the matrix elements of the Green function strong estimates are given that imply that the local statistics of any two ensembles in the bulk are identical if the first four moments of the matrix elements match. Universality at the spectral edges requires matching only two moments. A Wigner-type estimate is also proved, and it is shown that the eigenvalues repel each other on arbitrarily small scales."}],"day":"01","publication_status":"published","page":"507 - 626","date_published":"2011-01-01T00:00:00Z","_id":"2765","author":[{"full_name":"László Erdös","first_name":"László","last_name":"Erdös","id":"4DBD5372-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5366-9603"}],"type":"review","status":"public","year":"2011","date_updated":"2019-04-26T07:22:20Z","publisher":"IOP Publishing Ltd.","doi":"10.1070/RM2011v066n03ABEH004749","title":"Universality of Wigner random matrices: A survey of recent results","volume":66,"publication":"Russian Mathematical Surveys","publist_id":"4125","main_file_link":[{"open_access":"0","url":"http://arxiv.org/abs/1004.0861"}],"quality_controlled":0,"month":"01","intvolume":"        66","extern":1,"issue":"3","citation":{"chicago":"Erdös, László. “Universality of Wigner Random Matrices: A Survey of Recent Results.” <i>Russian Mathematical Surveys</i>.

Even for the well-studied case of pipe flow, it has not been possible to determine at what Reynolds number the motion will be either persistently turbulent or ultimately laminar. We show that in pipes, turbulence that is transient at low Reynolds numbers becomes sustained at a distinct critical point. Through extensive experiments and computer simulations, we were able to identify and characterize the processes ultimately responsible for sustaining turbulence.

We here investigate such spatially intermittent flows in a pipe experiment showing that turbulent puffs have a well-defined interaction distance, which sets their minimum spacing as well as the maximum observable turbulent fraction. Two methodologies are employed. Starting from a laminar flow, puffs are first created by locally injecting a jet of fluid through the pipe wall. When the perturbation is applied periodically at low frequencies, as expected, a regular sequence of puffs is observed where the puff spacing is given by the ratio of the mean flow speed to the perturbation frequency. At large frequencies however puffs are found to interact and annihilate each other. Varying the perturbation frequency, an interaction distance is determined which sets the highest possible turbulence fraction. This enables us to establish an upper bound for the friction factor in the transitional regime, which provides a well-defined link between the Blasius and the Hagen-Poiseuille friction laws. In the second set of experiments, the Reynolds number is reduced suddenly from fully turbulent to the intermittent regime. The resulting flow reorganizes itself to a sequence of constant size puffs which, unlike in Couette and Taylor–Couette flow are randomly spaced. The minimum distance between the turbulent patches is identical to the puff interaction length. The puff interaction length is found to be in agreement with the wavelength of regular stripe and spiral patterns in plane Couette and Taylor–Couette flow.","lang":"eng"}],"author":[{"last_name":"Samanta","first_name":"Devranjan","full_name":"Samanta, Devranjan"},{"last_name":"De Lózar","first_name":"Alberto","full_name":"de Lózar, Alberto"},{"full_name":"Björn Hof","first_name":"Björn","last_name":"Hof","id":"3A374330-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2057-2754"}],"_id":"2800","status":"public","type":"journal_article","doi":"10.1017/jfm.2011.189","publisher":"Cambridge University Press","date_updated":"2021-01-12T06:59:48Z","year":"2011"},{"title":"A Lagrangian approach to the interface velocity of turbulent puffs in pipe flow","volume":318,"month":"09","publist_id":"4088","quality_controlled":0,"conference":{"name":"ETC13: European Turbulence Conference"},"extern":1,"issue":"5","intvolume":"       318","alternative_title":["Journal of Physics: Conference Series"],"date_created":"2018-12-11T11:59:40Z","citation":{"chicago":"Holzner, Markus, Marc Avila, Alberto De Lózar, and Björn Hof. “A Lagrangian Approach to the Interface Velocity of Turbulent Puffs in Pipe Flow,” Vol. 318.

The level of GA activity determines the speed of hook formation and the extent of the curvature during the formation phase independently of ethylene, probably by modulating auxin transport and response through HLS1, PIN3, and PIN7.

Promoters often contain multiple copies of the same TF binding sites. How does this multiplicity evolve? One possibility is that individuals with multiple, redundant binding sites have higher fitness. However, nonadaptive processes are also likely to be important. Here, we develop a mathematical model of the evolution of TF binding sites to help us disentangle how different evolutionary mechanisms contribute to the evolution of binding site redundancy and multiplicity. We show that recombination is expected to promote the evolution of multiple binding sites. This prediction is corroborated by genome-wide data from yeast. Another important factor in the evolution of multiplicity predicted in our analysis is TF promiscuity, that is, the ability of a TF to bind to multiple sequences. In addition, our analysis indicated that direct selection can have large effects on the evolution of redundancy and multiplicity. Data from yeast identified selection for changes in expression level as a candidate mechanism for the evolution of multiple binding sites. We conclude that, although selection may play a major role in the evolution of multiplicity in regulatory regions, nonadaptive forces can also lead to high levels of multiplicity.","date_created":"2018-12-11T12:00:13Z","intvolume":"         6","extern":1,"issue":"7","quality_controlled":0,"publist_id":"3861","month":"01","volume":6,"title":"Redundancy and the Evolution of Cis Regulatory Element Multiplicity","publication":"PLoS Computational Biology"},{"citation":{"ama":"Paixao T, Phadke S, Azevedo R, Zufall R.

Much of this theory focuses on parental sex determination (SD) strategies. Here, we consider instead the evolutionary causes and consequences of mixed offspring SD strategies, in which the genotype of an individual determines not its sex, but the probability of developing one of multiple sexes. We find that alleles specifying mixed offspring SD strategies can generally outcompete alleles that specify pure strategies, but generate constraints that may prevent a population from reaching an even sex ratio. We use our model to analyze sex ratios in natural populations of Tetrahymena thermophila, a ciliate with seven sexes determined by mixed SD alleles. We show that probabilistic SD is sufficient to account for the occurrence of skewed sex ratios in natural populations of T. thermophila, provided that their effective population sizes are small. Our results highlight the importance of genetic drift in sex ratio evolution and suggest that mixed offspring SD strategies should be more common than currently thought."}],"day":"01","date_published":"2011-03-01T00:00:00Z","publication_status":"published","page":"2050 - 2060"},{"type":"book_chapter","status":"public","year":"2011","publisher":"Massachusetts Institute of Technology Press","date_updated":"2021-01-12T07:00:43Z","day":"01","date_published":"2011-01-01T00:00:00Z","publication_status":"published","_id":"2922","author":[{"full_name":"Vicente, Sara","first_name":"Sara","last_name":"Vicente"},{"first_name":"Vladimir","full_name":"Vladimir Kolmogorov","last_name":"Kolmogorov","id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Rother","first_name":"Carsten","full_name":"Rother, Carsten"}],"editor":[{"last_name":"Blake","full_name":"Blake, Andrew","first_name":"Andrew"},{"last_name":"Kohli","first_name":"Pushmeet","full_name":"Kohli, Pushmeet"},{"first_name":"Carsten","full_name":"Rother, Carsten","last_name":"Rother"}],"extern":1,"citation":{"apa":"Vicente, S., Kolmogorov, V., &#38; Rother, C.
