With heating measured by the buoyancy parameter 𝐶, our direct numerical simulations show that shear-driven turbulence may either be completely laminarised or it transitions to a relatively quiescent convection-driven state. Buoyancy forces cause a flattening of the base flow profile, which in isothermal pipe flow has recently been linked to complete suppression of turbulence (Kühnen et al., Nat. Phys., vol. 14, 2018, pp. 386–390), and the flattened laminar base profile has enhanced nonlinear stability (Marensi et al., J. Fluid Mech., vol. 863, 2019, pp. 50–875). In agreement with these findings, the nonlinear lower-branch travelling-wave solution analysed here, which is believed to mediate transition to turbulence in isothermal pipe flow, is shown to be suppressed by buoyancy. A linear instability of the laminar base flow is responsible for the appearance of the relatively quiescent convection driven state for 𝐶≳4 across the range of Reynolds numbers considered. In the suppression of turbulence, however, i.e. in the transition from turbulence, we find clearer association with the analysis of He et al. (J. Fluid Mech., vol. 809, 2016, pp. 31–71) than with the above dynamical systems approach, which describes better the transition to turbulence. The laminarisation criterion He et al. propose, based on an apparent Reynolds number of the flow as measured by its driving pressure gradient, is found to capture the critical 𝐶=𝐶𝑐𝑟(𝑅𝑒) above which the flow will be laminarised or switch to the convection-driven type. Our analysis suggests that it is the weakened rolls, rather than the streaks, which appear to be critical for laminarisation."}],"publication_status":"published","quality_controlled":"1","arxiv":1,"oa_version":"Published Version","doi":"10.1017/jfm.2021.371","day":"25","publisher":"Cambridge University Press","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"department":[{"_id":"BjHo"}],"publication_identifier":{"issn":["00221120"],"eissn":["14697645"]},"isi":1,"author":[{"full_name":"Marensi, Elena","last_name":"Marensi","first_name":"Elena","id":"0BE7553A-1004-11EA-B805-18983DDC885E"},{"first_name":"Shuisheng","last_name":"He","full_name":"He, Shuisheng"},{"first_name":"Ashley P.","last_name":"Willis","full_name":"Willis, Ashley P."}],"year":"2021"},{"month":"05","title":"Extending drawings of complete graphs into arrangements of pseudocircles","date_updated":"2023-08-08T13:58:12Z","ec_funded":1,"date_published":"2021-05-20T00:00:00Z","article_processing_charge":"No","page":"1050-1076","publication":"SIAM Journal on Discrete Mathematics","date_created":"2021-06-06T22:01:30Z","external_id":{"isi":["000674142200022"],"arxiv":["2001.06053"]},"project":[{"call_identifier":"H2020","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships"}],"_id":"9468","volume":35,"main_file_link":[{"url":"https://arxiv.org/abs/2001.06053","open_access":"1"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","issue":"2","intvolume":"        35","oa":1,"scopus_import":"1","publication_identifier":{"issn":["08954801"]},"department":[{"_id":"UlWa"}],"isi":1,"author":[{"orcid":"0000-0003-2401-8670","full_name":"Arroyo Guevara, Alan M","last_name":"Arroyo Guevara","first_name":"Alan M","id":"3207FDC6-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Richter","full_name":"Richter, R.

A spherical drawing of a graph $G$ is a drawing in the unit sphere $\\mathbb{S}^2$ in which the vertices of $G$ are represented as points---no three on a great circle---and the edges of $G$ are shortest-arcs in $\\mathbb{S}^2$ connecting pairs of vertices. Such a drawing has three properties: (1) every edge $e$ is contained in a simple closed curve $\\gamma_e$ such that the only vertices in $\\gamma_e$ are the ends of $e$; (2) if $e\\ne f$, then $\\gamma_e\\cap\\gamma_f$ has precisely two crossings; and (3) if $e\\ne f$, then $e$ intersects $\\gamma_f$ at most once, in either a crossing or an end of $e$. We use properties (1)--(3) to define a pseudospherical drawing of $G$. Our main result is that for the complete graph, properties (1)--(3) are equivalent to the same three properties but with “precisely two crossings” in (2) replaced by “at most two crossings.” The proof requires a result in the geometric transversal theory of arrangements of pseudocircles. This is proved using the surprising result that the absence of special arcs (coherent spirals) in an arrangement of simple closed curves characterizes the fact that any two curves in the arrangement have at most two crossings. Our studies provide the necessary ideas for exhibiting a drawing of $K_{10}$ that has no extension to an arrangement of pseudocircles and a drawing of $K_9$ that does extend to an arrangement of pseudocircles, but no such extension has all pairs of pseudocircles crossing twice.\r\n","lang":"eng"}],"publication_status":"published","quality_controlled":"1","citation":{"short":"A.M.

Recent work has focused on the regime in which machines have sublinear (in n, the number of nodes in the input graph) space, with randomized algorithms presented for the fundamental problems of Maximal Matching and Maximal Independent Set. However, there have been no prior corresponding deterministic algorithms. A major challenge underlying the sublinear space setting is that the local space of each machine might be too small to store all edges incident to a single node. This poses a considerable obstacle compared to classical models in which each node is assumed to know and have easy access to its incident edges. To overcome this barrier, we introduce a new graph sparsification technique that deterministically computes a low-degree subgraph, with the additional property that solving the problem on this subgraph provides significant progress towards solving the problem for the original input graph. Using this framework to derandomize the well-known algorithm of Luby [SICOMP’86], we obtain O(log Δ + log log n)-round deterministic MPC algorithms for solving the problems of Maximal Matching and Maximal Independent Set with O(nɛ) space on each machine for any constant ɛ > 0. These algorithms also run in O(log Δ) rounds in the closely related model of CONGESTED CLIQUE, improving upon the state-of-the-art bound of O(log 2Δ) rounds by Censor-Hillel et al.

DME is a fundamental construct in distributed machine learning, and there has been considerable work on variants of this problem, especially in the context of distributed variance reduction for stochastic gradients in parallel SGD. Previous work typically assumes an upper bound on the norm of the input vectors, and achieves an error bound in terms of this norm. However, in many real applications, the input vectors are concentrated around the correct output μ, but μ itself has large norm. In such cases, previous output error bounds perform poorly. In this paper, we show that output error bounds need not depend on input norm. We provide a method of quantization which allows distributed mean estimation to be performed with solution quality dependent only on the distance between inputs, not on input norm, and show an analogous result for distributed variance reduction. The technique is based on a new connection with lattice theory. We also provide lower bounds showing that the communication to error trade-off of our algorithms is asymptotically optimal. As the lattices achieving optimal bounds under l2-norm can be computationally impractical, we also present an extension which leverages easy-to-use cubic lattices, and is loose only up to a logarithmic factor ind. We show experimentally that our method yields practical improvements for common applications, relative to prior approaches."}],"oa":1,"user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","quality_controlled":"1","citation":{"mla":"Davies, Peter, et al. “New Bounds for Distributed Mean Estimation and Variance Reduction.” <i>9th International Conference on Learning Representations</i>, 2021.","ista":"Davies P, Gurunanthan V, Moshrefi N, Ashkboos S, Alistarh D-A. 2021.

A key challenge lies in the inherent translucency of commonly used print materials that blurs out details of the color texture. Previous work tries to compensate for these scattering effects through strategic assignment of colored primary materials to printer voxels. To date, the highest-quality approach uses iterative optimization that relies on computationally expensive Monte Carlo light transport simulation to predict the surface appearance from subsurface scattering within a given print material distribution; that optimization, however, takes in the order of days on a single machine. In our work, we dramatically speed up the process by replacing the light transport simulation with a data-driven approach. Leveraging a deep neural network to predict the scattering within a highly heterogeneous medium, our method performs around two orders of magnitude faster than Monte Carlo rendering while yielding optimization results of similar quality level. The network is based on an established method from atmospheric cloud rendering, adapted to our domain and extended by a physically motivated weight sharing scheme that substantially reduces the network size. We analyze its performance in an end-to-end print preparation pipeline and compare quality and runtime to alternative approaches, and demonstrate its generalization to unseen geometry and material values. This for the first time enables full heterogenous material optimization for 3D-print preparation within time frames in the order of the actual printing time.","lang":"eng"}],"publication_status":"published","quality_controlled":"1","oa_version":"Submitted Version","doi":"10.1111/cgf.142626","day":"01","publisher":"Wiley","publication_identifier":{"issn":["0167-7055"],"eissn":["1467-8659"]},"department":[{"_id":"BeBi"}],"isi":1,"author":[{"first_name":"Tobias","full_name":"Rittig, Tobias","last_name":"Rittig"},{"full_name":"Sumin, Denis","last_name":"Sumin","first_name":"Denis"},{"first_name":"Vahid","full_name":"Babaei, Vahid","last_name":"Babaei"},{"last_name":"Didyk","full_name":"Didyk, Piotr","first_name":"Piotr"},{"first_name":"Alexey","last_name":"Voloboy","full_name":"Voloboy, Alexey"},{"first_name":"Alexander","full_name":"Wilkie, Alexander","last_name":"Wilkie"},{"full_name":"Bickel, Bernd","orcid":"0000-0001-6511-9385","last_name":"Bickel","id":"49876194-F248-11E8-B48F-1D18A9856A87","first_name":"Bernd"},{"last_name":"Myszkowski","full_name":"Myszkowski, Karol","first_name":"Karol"},{"last_name":"Weyrich","full_name":"Weyrich, Tim","first_name":"Tim"},{"last_name":"Křivánek","full_name":"Křivánek, Jaroslav","first_name":"Jaroslav"}],"year":"2021","scopus_import":"1","volume":40,"issue":"2","acknowledgement":"We thank Sebastian Cucerca for processing and capturing the phys-cal printouts.

However, their mechanisms of action are poorly understood. Here we determine cryo-electron microscopy structures of the heteromeric GluA1–GluA2 receptor assembled with both TARP-γ8 and CNIH2, the predominant AMPAR complex in the forebrain, in both resting and active states. Two TARP-γ8 and two CNIH2 subunits insert at distinct sites beneath the ligand-binding domains of the receptor, with site-specific lipids shaping each interaction and affecting the gating regulation of the AMPARs. Activation of the receptor leads to asymmetry between GluA1 and GluA2 along the ion conduction path and an outward expansion of the channel triggers counter-rotations of both auxiliary subunit pairs, promoting the active-state conformation. In addition, both TARP-γ8 and CNIH2 pivot towards the pore exit upon activation, extending their reach for cytoplasmic receptor elements. CNIH2 achieves this through its uniquely extended M2 helix, which has transformed this endoplasmic reticulum-export factor into a powerful AMPAR modulator that is capable of providing hippocampal pyramidal neurons with their integrative synaptic properties.

The hippocampal CA3-CA1 pyramidal cell synaptic connection shows an input-side dependent asymmetry where the hemispheric location of the presynaptic CA3 neuron determines the synaptic properties. Left-input synapses terminating on apical dendrites in stratum radiatum have a higher density of NMDA receptor subunit GluN2B, a lower density of AMPA receptor subunit GluA1 and smaller areas with less often perforated PSDs. On the other hand, left-input synapses terminating on basal dendrites in stratum oriens have lower GluN2B densities than right-input ones. Apical and basal synapses further employ different signaling pathways involved in LTP. SDS-digested freeze-fracture replica labeling can visualize synaptic membrane proteins with high sensitivity and resolution, and has been used to reveal the asymmetry at the electron microscopic level. However, it requires time-consuming manual demarcation of the synaptic surface for quantitative measurements. To facilitate the analysis of replica labeling, I first developed a software named Darea, which utilizes deep-learning to automatize this demarcation. With Darea I characterized the synaptic distribution of NMDA and AMPA receptors as well as the voltage-gated Ca2+ channels in CA1 stratum radiatum and oriens. Second, I explored the role of GluN2B and its carboxy-terminus in the establishment of input-side dependent hippocampal asymmetry. In conditional knock-out mice lacking GluN2B expression in CA1 and GluN2B-2A swap mice, where GluN2B carboxy-terminus was exchanged to that of GluN2A, no significant asymmetries of GluN2B, GluA1 and PSD area were detected. We further discovered a previously unknown functional asymmetry of GluN2A, which was also lost in the swap mouse. These results demonstrate that GluN2B carboxy-terminus plays a critical role in normal formation of input-side dependent asymmetry.","lang":"eng"}],"publication_status":"published","language":[{"iso":"eng"}],"has_accepted_license":"1","status":"public","ddc":["570"],"acknowledged_ssus":[{"_id":"EM-Fac"}],"file":[{"embargo":"2022-07-01","creator":"dkleindienst","date_created":"2021-06-17T14:03:14Z","file_id":"9563","file_name":"Thesis.pdf","access_level":"open_access","checksum":"659df5518db495f679cb1df9e9bd1d94","relation":"main_file","content_type":"application/pdf","date_updated":"2022-07-02T22:30:04Z","file_size":77299142},{"date_created":"2021-06-17T14:04:30Z","creator":"dkleindienst","file_id":"9564","file_name":"Thesis_source.zip","embargo_to":"open_access","access_level":"closed","checksum":"3bcf63a2b19e5b6663be051bea332748","relation":"source_file","content_type":"application/zip","date_updated":"2022-07-02T22:30:04Z","file_size":369804895}],"citation":{"chicago":"Kleindienst, David. “2B or Not 2B: Hippocampal Asymmetries Mediated by NMDA Receptor Subunit GluN2B C-Terminus and High-Throughput Image Analysis by Deep-Learning.” Institute of Science and Technology Austria, 2021. <a href=\"https://doi.org/10.15479/at:ista:9562\">https://doi.org/10.15479/at:ista:9562</a>.","ama":"Kleindienst D. 2B or not 2B: Hippocampal asymmetries mediated by NMDA receptor subunit GluN2B C-terminus and high-throughput image analysis by Deep-Learning. 2021. doi:<a href=\"https://doi.org/10.15479/at:ista:9562\">10.15479/at:ista:9562</a>","mla":"Kleindienst, David. <i>2B or Not 2B: Hippocampal Asymmetries Mediated by NMDA Receptor Subunit GluN2B C-Terminus and High-Throughput Image Analysis by Deep-Learning</i>.

We adopted the wet chemical procedure, using various contents of Fe3O4 (magnetite) from 0–100% for making two-dimensional graphene–Fe3O4 nanohybrids. The homogeneous dispersal of Fe3O4 nanoparticles decorated on the graphene surface combined with their biocompatibility and high thermal conductivity make them an excellent material for magnetic hyperthermia. The morphological and magnetic properties of the nanohybrids were studied using scanning electron microscopy (SEM) and a vibrating sample magnetometer (VSM), respectively. The smart magnetic platforms were exposed to an alternating current (AC) magnetic field of 633 kHz and of strength 9.1 mT for studying their hyperthermic performance. The localized antitumor effects were investigated with artificial neural network modeling. A neural net time-series model was developed for the assessment of the best nanohybrid composition to serve the purpose with an accuracy close to 100%. Six Nonlinear Autoregressive with External Input (NARX) models were obtained, one for each of the components. The assessment of the accuracy of the predicted results has been done on the basis of Mean Squared Error (MSE). The highest Mean Squared Error value was obtained for the nanohybrid containing 45% magnetite and 55% graphene (F45G55) in the training phase i.e., 0.44703, which is where the model achieved optimal results after 71 epochs. The F45G55 nanohybrid was found to be the best for hyperthermia applications in low dosage with the highest specific absorption rate (SAR) and mean squared error values.","lang":"eng"}],"publication_status":"published","quality_controlled":"1"},{"publication_status":"published","abstract":[{"lang":"eng","text":"We present conductance-matrix measurements in long, three-terminal hybrid superconductor-semiconductor nanowires, and compare with theoretical predictions of a magnetic-field-driven, topological quantum phase transition.

One popular communication-compression method for data-parallel SGD is QSGD (Alistarh et al., 2017), which quantizes and encodes gradients to reduce communication costs. The baseline variant of QSGD provides strong theoretical guarantees, however, for practical purposes, the authors proposed a heuristic variant which we call QSGDinf, which demonstrated impressive empirical gains for distributed training of large neural networks. In this paper, we build on this work to propose a new gradient quantization scheme, and show that it has both stronger theoretical guarantees than QSGD, and matches and exceeds the empirical performance of the QSGDinf heuristic and of other compression methods.","lang":"eng"}],"language":[{"iso":"eng"}],"status":"public","has_accepted_license":"1"}]
