We also show that there is 100% Bose-Einstein condensation. While a proof that the GP equation correctly describes non-rotating or slowly rotating gases was known for some time, the rapidly rotating case was unclear because the Bose (i.e., symmetric) ground state is not the lowest eigenstate of the Hamiltonian in this case. We have been able to overcome this difficulty with the aid of coherent states. Our proof also conceptually simplifies the previous proof for the slowly rotating case. In the case of axially symmetric traps, our results show that the appearance of quantized vortices causes spontaneous symmetry breaking in the ground state.

In [1] a model of this phenomenon has been analyzed rigorously. The gas is a hard core lattice gas and the optical lattice is modeled by a periodic potential of strength λ. For small λ and temperature Bose- Einstein condensation (BEC) is proved to occur, while at large λ BEC disappears, even in the ground state, which is a Mott-insulator state with a characteristic gap. The inter-particle interaction is essential for this effect. This contribution gives a pedagogical survey of these results. alternative_title: - LNP author: - first_name: Michael full_name: Aizenman, Michael last_name: Aizenman - first_name: Élliott full_name: Lieb, Élliott H last_name: Lieb - first_name: Robert full_name: Robert Seiringer id: 4AFD0470-F248-11E8-B48F-1D18A9856A87 last_name: Seiringer orcid: 0000-0002-6781-0521 - first_name: Jan full_name: Solovej, Jan P last_name: Solovej - first_name: Jakob full_name: Yngvason, Jakob last_name: Yngvason citation: ama: 'Aizenman M, Lieb É, Seiringer R, Solovej J, Yngvason J.

We present deterministic and randomized algorithms for achieving this goal, and analyze their performance, that is, the maximum number of colors that they need to use, as a function of the number n of inserted points. We first show that a natural and simple (deterministic) approach may perform rather poorly, requiring Ω(√̃) colors in the worst case. We then derive two efficient variants of this simple algorithm. The first is deterministic and uses O(log 2 n) colors, and the second is randomized and uses O(log n) colors with high probability. We also show that the O(log 2 n) bound on the number of colors used by our deterministic algorithm is tight on the worst case. We also analyze the performance of the simplest proposed algorithm when the points are inserted in a random order and present an incomplete analysis that indicates that, with high probability, it uses only O(log n) colors. Finally, we show that in the extension of this problem to two dimensions, where the relevant ranges are disks, n colors may be required in the worst case. author: - first_name: Ke full_name: Chent, Ke last_name: Chent - first_name: Amos full_name: Fiat, Amos last_name: Fiat - first_name: Haim full_name: Kaplan, Haim last_name: Kaplan - first_name: Meital full_name: Levy, Meital B last_name: Levy - first_name: Jiří full_name: Matoušek, Jiří last_name: Matoušek - first_name: Elchanan full_name: Mossel, Elchanan last_name: Mossel - first_name: János full_name: Pach, János last_name: Pach - first_name: Micha full_name: Sharir, Micha last_name: Sharir - first_name: Shakhar full_name: Smorodinsky, Shakhar last_name: Smorodinsky - first_name: Uli full_name: Uli Wagner id: 36690CA2-F248-11E8-B48F-1D18A9856A87 last_name: Wagner orcid: 0000-0002-1494-0568 - first_name: Emo full_name: Welzl, Emo last_name: Welzl citation: ama: Chent K, Fiat A, Kaplan H, et al.

This partially settles a conjecture of Eckhoff, Linhart, and Welzl. Up to the factor of 2, the result generalizes McMullen's Upper Bound Theorem for convex polytopes (the case ℓ = O) and extends a theorem of Linhart for the case d ≤ 4. Moreover, the bound sharpens asymptotic estimates obtained by Clarkson and Shor. The proof is based on the h-matrix of the arrangement (a generalization, introduced by Mulmuley, of the h-vector of a convex polytope). We show that bounding appropriate sums of entries of this matrix reduces to a lemma about quadrupels of sets with certain intersection properties, and we prove this lemma, up to a factor of 2, using tools from multilinear algebra. This extends an approach of Alon and Kalai, who used linear algebra methods for an alternative proof of the classical Upper Bound Theorem. The bounds for the entries of the h-matrix also imply bounds for the number of i-dimensional faces, i > 0, at level at most ℓ. Furthermore, we discuss a connection with crossing numbers of graphs that was one of the main motivations for investigating exact bounds that are valid for arbitrary dimensions. alternative_title: - IEEE Conference Proceedings author: - first_name: Uli full_name: Uli Wagner id: 36690CA2-F248-11E8-B48F-1D18A9856A87 last_name: Wagner orcid: 0000-0002-1494-0568 citation: ama: 'Wagner U.

TARPs may also act as a positive modulator of the AMPA receptor ion channel function; however, little is known about other TARP members except for stargazin/γ-2. We examined the synaptic localization of stargazin/γ-2 and γ-8 by immunoelectron microscopy and biochemical analysis. The analysis of sodium dodecyl sulfate-digested freeze-fracture replica labeling revealed that stargazin/γ-2 was concentrated in the postsynaptic area, whereas γ-8 was distributed both in synaptic and extra-synaptic plasma membranes of the hippocampal neuron. When a synaptic plasma membrane-enriched brain fraction was treated with Triton X-100 and separated by sucrose density gradient ultracentrifugation, a large proportion of NMDA receptor and stargazin/γ-2 was accumulated in raft-enriched fractions, whereas AMPA receptor and γ-8 were distributed in both the raft-enriched fractions and other Triton-insoluble fractions. Phosphorylation of stargazin/γ-2 and γ-8 was regulated by different sets of kinases and phosphatases in cultured cortical neurons. These results suggested that stargazin/γ-2 and γ-8 have distinct roles in postsynaptic membranes under the regulation of different intracellular signaling pathways. author: - first_name: Mihoko full_name: Inamura, Mihoko last_name: Inamura - first_name: Makoto full_name: Itakura, Makoto last_name: Itakura - first_name: Hirotsugu full_name: Okamoto, Hirotsugu last_name: Okamoto - first_name: Sumio full_name: Hoka, Sumio last_name: Hoka - first_name: Akira full_name: Mizoguchi, Akira last_name: Mizoguchi - first_name: Yugo full_name: Fukazawa, Yugo last_name: Fukazawa - first_name: Ryuichi full_name: Ryuichi Shigemoto id: 499F3ABC-F248-11E8-B48F-1D18A9856A87 last_name: Shigemoto orcid: 0000-0001-8761-9444 - first_name: Saori full_name: Yamamori, Saori last_name: Yamamori - first_name: Masami full_name: Takahashi, Masami last_name: Takahashi citation: ama: Inamura M, Itakura M, Okamoto H, et al.

In order to determine how this distribution is achieved during development, we investigated the expression pattern and the cellular and subcellular localization of the GABAB1 and GABAB2 subunits in the rat cerebellum during postnatal development. At the light microscopic level, immunoreactivity for the GABAB1 and GABAB2 subunits was very prominent in the developing molecular layer, especially in Purkinje cells. Using double immunofluorescence, we demonstrated that GABAB1 was transiently expressed in glial cells. At the electron microscopic level, immunoreactivity for GABAB receptors was always detected both pre- and postsynaptically. Presynaptically, GABAB1 and GABAB2 were localized in the extrasynaptic membrane of parallel fibres at all ages, and only rarely in GABAergic axons. Postsynaptically, GABAB receptors were localized to the extrasynaptic and perisynaptic plasma membrane of Purkinje cell dendrites and spines throughout development. Quantitative analysis and three-dimensional reconstructions further revealed a progressive developmental movement of the GABAB1 subunit on the surface of Purkinje cells from dendritic shafts to its final destination, the dendritic spines. Together, these results indicate that GABAB receptors undergo dynamic regulation during cerebellar development in association with the establishment and maturation of glutamatergic synapses to Purkinje cells. author: - first_name: Rafael full_name: Luján, Rafael last_name: Luján - first_name: Ryuichi full_name: Ryuichi Shigemoto id: 499F3ABC-F248-11E8-B48F-1D18A9856A87 last_name: Shigemoto orcid: 0000-0001-8761-9444 citation: ama: Luján R, Shigemoto R.

We studied the basic characteristics of the rocker mutant Ca2+ channel and their impacts on excitatory synaptic transmission in cerebellar Purkinje cells (PCs). In acutely dissociated PC somas, the rocker mutant channel showed a moderate reduction in Ca2+ channel current density, whereas its kinetics and voltage dependency of gating remained nearly normal. Despite the small changes in channel function, synaptic transmission in the parallel fiber (PF)-PC synapses was severely impaired. The climbing fiber inputs onto PCs showed a moderate impairment but could elicit normal complex spikes. Presynaptic function of the PF-PC synapses, however, was unexpectedly almost normal in terms of paired-pulse facilitation, sensitivity to extracellular Ca2+ concentration and glutamate concentration in synaptic clefts. Electron microscopic analyses including freeze-fracture replica labeling revealed that both the number and density of postsynaptic α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors substantially decreased without gross structural changes of the PF-PC synapses. We also observed an abnormal arborization of PC dendrites in young adult rocker mice (∼ 1 month old). These lines of evidence suggest that even a moderate dysfunction of CaV2.1 Ca2+ channel can cause substantial changes in postsynaptic molecular composition of the PF-PC synapses and dendritic structure of PCs. author: - first_name: Takashi full_name: Kodama, Takashi last_name: Kodama - first_name: Yuko full_name: Itsukaichi-Nishida, Yuko last_name: Itsukaichi Nishida - first_name: Yugo full_name: Fukazawa, Yugo last_name: Fukazawa - first_name: Minoru full_name: Wakamori, Minoru last_name: Wakamori - first_name: Mariko full_name: Miyata, Mariko last_name: Miyata - first_name: Elek full_name: Molnár, Elek last_name: Molnár - first_name: Yasuo full_name: Mori, Yasuo last_name: Mori - first_name: Ryuichi full_name: Ryuichi Shigemoto id: 499F3ABC-F248-11E8-B48F-1D18A9856A87 last_name: Shigemoto orcid: 0000-0001-8761-9444 - first_name: Keiji full_name: Imoto, Keiji last_name: Imoto citation: ama: Kodama T, Itsukaichi Nishida Y, Fukazawa Y, et al.

Molecular diversity in the GABAB system arises from the GABAB1a and GABAB1b subunit isoforms that solely differ in their ectodomains by a pair of sushi repeats that is unique to GABAB1a. Using a combined genetic, physiological, and morphological approach, we now demonstrate that GABAB1 isoforms localize to distinct synaptic sites and convey separate functions in vivo. At hippocampal CA3-to-CA1 synapses, GABAB1a assembles heteroreceptors inhibiting glutamate release, while predominantly GABAB1b mediates postsynaptic inhibition. Electron microscopy reveals a synaptic distribution of GABAB1 isoforms that agrees with the observed functional differences. Transfected CA3 neurons selectively express GABAB1a in distal axons, suggesting that the sushi repeats, a conserved protein interaction motif, specify heteroreceptor localization. The constitutive absence of GABAB1a but not GABAB1b results in impaired synaptic plasticity and hippocampus-dependent memory, emphasizing molecular differences in synaptic GABAB functions. author: - first_name: Réjan full_name: Vigot, Réjan last_name: Vigot - first_name: Samuel full_name: Barbieri, Samuel last_name: Barbieri - first_name: Hans full_name: Bräuner-Osborne, Hans last_name: Bräuner Osborne - first_name: Rostislav full_name: Tureček, Rostislav last_name: Tureček - first_name: Ryuichi full_name: Ryuichi Shigemoto id: 499F3ABC-F248-11E8-B48F-1D18A9856A87 last_name: Shigemoto orcid: 0000-0001-8761-9444 - first_name: Yan full_name: Zhang, Yan Ping last_name: Zhang - first_name: Rafael full_name: Luján, Rafael last_name: Luján - first_name: Laura full_name: Jacobson, Laura H last_name: Jacobson - first_name: Barbara full_name: Biermann, Barbara last_name: Biermann - first_name: Jean full_name: Fritschy, Jean-Marc last_name: Fritschy - first_name: Claire full_name: Vacher, Claire-Marie last_name: Vacher - first_name: Matthias full_name: Müller, Matthias P last_name: Müller - first_name: Gilles full_name: Sansig, Gilles last_name: Sansig - first_name: Nicole full_name: Guetg, Nicole last_name: Guetg - first_name: John full_name: Cryan, John F last_name: Cryan - first_name: Klemens full_name: Kaupmann, Klemens last_name: Kaupmann - first_name: Martin full_name: Gassmann, Martin last_name: Gassmann - first_name: Thomas full_name: Oertner, Thomas G last_name: Oertner - first_name: Bernhard full_name: Bettler, Bernhard last_name: Bettler citation: ama: Vigot R, Barbieri S, Bräuner Osborne H, et al.

To determine the distribution of Kir3 channels and their spatial relationship to GABAB receptors on hippocampal pyramidal cells, we used a high-resolution immunocytochemical approach. Immunoreactivity for the Kir3.2 subunit was most abundant postsynaptically and localized to the extrasynaptic plasma membrane of dendritic shafts and spines of principal cells. Quantitative analysis of immunogold particles for Kir3.2 revealed an enrichment of the protein around putative glutamatergic synapses on dendritic spines, similar to that of GABA B1. Consistent with this observation, a high degree of coclustering of Kir3.2 and GABAB1 was revealed around excitatory synapses by the highly sensitive SDS-digested freeze-fracture replica immunolabeling. In contrast, in dendritic shafts receptors and channels were found to be mainly segregated. These results suggest that Kir3.2-containing K+ channels on dendritic spines preferentially mediate the effect of GABA, whereas channels on dendritic shafts are likely to be activated by other neurotransmitters as well. Thus, Kir3 channels, localized to different subcellular compartments of hippocampal principal cells, appear to be differentially involved in synaptic integration in pyramidal cell dendrites. author: - first_name: Ákos full_name: Kulik, Ákos last_name: Kulik - first_name: Imre full_name: Vida, Imre last_name: Vida - first_name: Yugo full_name: Fukazawa, Yugo last_name: Fukazawa - first_name: Nicole full_name: Guetg, Nicole last_name: Guetg - first_name: Yu full_name: Kasugai, Yu last_name: Kasugai - first_name: Cheryl full_name: Marker, Cheryl L last_name: Marker - first_name: Franck full_name: Rigato, Franck last_name: Rigato - first_name: Bernhard full_name: Bettler, Bernhard last_name: Bettler - first_name: Kevin full_name: Wickman, Kevin D last_name: Wickman - first_name: Michael full_name: Frotscher, Michael last_name: Frotscher - first_name: Ryuichi full_name: Ryuichi Shigemoto id: 499F3ABC-F248-11E8-B48F-1D18A9856A87 last_name: Shigemoto orcid: 0000-0001-8761-9444 citation: ama: Kulik Á, Vida I, Fukazawa Y, et al.

Using a combined genetic and electrophysiological approach, we show here that lack of a specific GABAB receptor subtype, GABAB(1a,2), unmasks a nonassociative, NMDA receptor-independent form of presynaptic LTP at cortico-amygdala afferents. Moreover, the level of presynaptic GABA B(1a,2) receptor activation, and hence the balance between associative and nonassociative forms of LTP, can be dynamically modulated by local inhibitory activity. At the behavioral level, genetic loss of GABA B(1a) results in a generalization of conditioned fear to nonconditioned stimuli. Our findings indicate that presynaptic inhibition through GABAB(1a,2) receptors serves as an activity-dependent constraint on the induction of homosynaptic plasticity, which may be important to prevent the generalization of conditioned fear. author: - first_name: Hamdy full_name: Shaban, Hamdy last_name: Shaban - first_name: Yann full_name: Humeau, Yann last_name: Humeau - first_name: Cyril full_name: Herry, Cyril last_name: Herry - first_name: Guillaume full_name: Cassasus, Guillaume last_name: Cassasus - first_name: Ryuichi full_name: Ryuichi Shigemoto id: 499F3ABC-F248-11E8-B48F-1D18A9856A87 last_name: Shigemoto orcid: 0000-0001-8761-9444 - first_name: Stéphane full_name: Ciocchi, Stéphane last_name: Ciocchi - first_name: Samuel full_name: Barbieri, Samuel last_name: Barbieri - first_name: Herman full_name: Van Der Putten, Herman V last_name: Van Der Putten - first_name: Klemens full_name: Kaupmann, Klemens last_name: Kaupmann - first_name: Bernhard full_name: Bettler, Bernhard last_name: Bettler - first_name: Andreas full_name: Lüthi, Andreas last_name: Lüthi citation: ama: Shaban H, Humeau Y, Herry C, et al.

Molecular cloning has revealed eight different subtypes (mGlu1-8) with distinct molecular and pharmacological properties. Multiplicity in this receptor family is further generated through alternative splicing. mGlus activate a multitude of signalling pathways important for modulating neuronal excitability, synaptic plasticity and feedback regulation of neurotransmitter release. In this review, we summarize anatomical findings (from our work and that of other laboratories) describing their distribution in the central nervous system. Recent evidence regarding the localization of these receptors in peripheral tissues will also be examined. The distinct regional, cellular and subcellular distribution of mGlus in the brain will be discussed in view of their relationship to neurotransmitter release sites and of possible functional implications. author: - first_name: Francesco full_name: Ferraguti, Francesco last_name: Ferraguti - first_name: Ryuichi full_name: Ryuichi Shigemoto id: 499F3ABC-F248-11E8-B48F-1D18A9856A87 last_name: Shigemoto orcid: 0000-0001-8761-9444 citation: ama: Ferraguti F, Shigemoto R.

Suppose that the initial data ψ N,0 satisfies the condition 〈ψ N,0, H 2 Nψ N,0) ≤ C N 2 where H N is the Hamiltonian of the Bose system. This condition is satisfied if ψ N,0 = W Nφ N,t where W N is an approximate ground state to H N and φ N,0 is regular. Let ψ N,t denote the solution to the Schrödinger equation with Hamiltonian H N. Gross and Pitaevskii proposed to model the dynamics of such a system by a nonlinear Schrödinger equation, the Gross-Pitaevskii (GP) equation. The GP hierarchy is an infinite BBGKY hierarchy of equations so that if u t solves the GP equation, then the family of k-particle density matrices ⊗ k |u t?〉 〈 t | solves the GP hierarchy. We prove that as N → ∞ the limit points of the k-particle density matrices of ψ N,t are solutions of the GP hierarchy. Our analysis requires that the N-boson dynamics be described by a modified Hamiltonian that cuts off the pair interactions whenever at least three particles come into a region with diameter much smaller than the typical interparticle distance. Our proof can be extended to a modified Hamiltonian that only forbids at least n particles from coming close together for any fixed n. author: - first_name: László full_name: László Erdös id: 4DBD5372-F248-11E8-B48F-1D18A9856A87 last_name: Erdös orcid: 0000-0001-5366-9603 - first_name: Benjamin full_name: Schlein, Benjamin last_name: Schlein - first_name: Horng full_name: Yau, Horng-Tzer last_name: Yau citation: ama: Erdös L, Schlein B, Yau H.
