Maximum likelihood estimation for this class of models leads to a non-convex optimization problem which typically has many local maxima. Using recent results on the asymptotic distribution of extreme eigenvalues of the Wishart distribution, we provide sufficient conditions for any hill climbing method to converge to the global maximum. Although we are primarily interested in the case in which n≫p, the proofs of our results utilize large sample asymptotic theory under the scheme n/p→γ&gt;1. Remarkably, our numerical simulations indicate that our results remain valid for p as small as 2.

The simplest, and very common symmetry of this type is the equivariance of the defining equations under the orthogonal group O(2). We formulate a novel symmetry reduction scheme for such systems by combining the method of slices with invariant polynomial methods, and show how it works by applying it to the Kuramoto–Sivashinsky system in one spatial dimension. As an example, we track a relative periodic orbit through a sequence of bifurcations to the onset of chaos. Within the symmetry-reduced state space we are able to compute and visualize the unstable manifolds of relative periodic orbits, their torus bifurcations, a transition to chaos via torus breakdown, and heteroclinic connections between various relative periodic orbits. It would be very hard to carry through such analysis in the full state space, without a symmetry reduction such as the one we present here.","lang":"eng"}],"citation":{"mla":"Budanur, Nazmi B., and Predrag Cvitanović. “Unstable Manifolds of Relative Periodic Orbits in the Symmetry Reduced State Space of the Kuramoto–Sivashinsky System.” <i>Journal of Statistical Physics</i>, vol. 167, no. 3–4, Springer, 2017, pp. 636–55, doi:<a href=\"https://doi.org/10.1007/s10955-016-1672-z\">10.1007/s10955-016-1672-z</a>.","apa":"Budanur, N.

Its primary component is FtsZ, a tubulin-like GTPase, that like its eukaryotic relative forms protein filaments in the presence of GTP. Since the discovery of the Z-ring 25 years ago, various models for the role of FtsZ have been suggested. However, important information about the architecture and dynamics of FtsZ filaments during cytokinesis is still missing. One reason for this lack of knowledge has been the small size of bacteria, which has made it difficult to resolve the orientation and dynamics of individual FtsZ filaments in the Z-ring. While superresolution microscopy experiments have helped to gain more information about the organization of the Z-ring in the dividing cell, they were not yet able to elucidate a mechanism of how FtsZ filaments reorganize during assembly and disassembly of the Z-ring. In this chapter, we explain how to use an in vitro reconstitution approach to investigate the self-organization of FtsZ filaments recruited to a biomimetic lipid bilayer by its membrane anchor FtsA. We show how to perform single-molecule experiments to study the behavior of individual FtsZ monomers during the constant reorganization of the FtsZ-FtsA filament network. We describe how to analyze the dynamics of single molecules and explain why this information can help to shed light onto possible mechanism of Z-ring constriction. We believe that similar experimental approaches will be useful to study the mechanism of membrane-based polymerization of other cytoskeletal systems, not only from prokaryotic but also eukaryotic origin."}],"scopus_import":"1","publication_identifier":{"issn":["0091679X"]},"citation":{"apa":"Baranova, N.

This review provides a summary of 19 publications on reprogrammed adult somatic cells derived from patients with SCZ, and five publications using this technique in patients with BPD. As both disorders are complex and heterogeneous, there is a plurality of hypotheses to be tested in vitro. In SCZ, data on alterations of dopaminergic transmission in vitro are sparse, despite the great explanatory power of the so-called DA hypothesis of SCZ. Some findings correspond to perturbations of cell energy metabolism, and observations in reprogrammed cells suggest neuro-developmental alterations. Some studies also report on the efficacy of medicinal compounds to revert alterations observed in cellular models. However, due to the paucity of replication studies, no comprehensive conclusions can be drawn from studies using reprogrammed cells at the present time. In the future, findings from cell culture methods need to be integrated with clinical, epidemiological, pharmacological and imaging data in order to generate a more comprehensive picture of SCZ and BPD."}],"scopus_import":"1","file_date_updated":"2020-07-14T12:44:39Z","type":"journal_article","_id":"1228","quality_controlled":"1","publication_status":"published","date_published":"2017-01-01T00:00:00Z","intvolume":"        45","month":"01","acknowledgement":"This work was supported by grants of the Austrian Science Fund (FWF) P23585B09 to M.W. and F3506 to H.H.S. and the “Wiener Wissenschafts-, Forschungs- und Technologiefonds” (Vienna Science and Technology Fund; WWTF) CS15-033 to M.W.","date_updated":"2023-09-20T11:16:01Z","oa":1,"issue":"1","external_id":{"pmid":["27690184"],"isi":["000392487100005"]},"page":"45 - 57","year":"2017","volume":45,"pmid":1,"tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"date_created":"2018-12-11T11:50:50Z","ddc":["616"],"day":"01","status":"public","publication":"European Journal of Neuroscience","doi":"10.1111/ejn.13418","oa_version":"Published Version","isi":1},{"oa":1,"issue":"11","date_updated":"2021-01-12T06:49:14Z","acknowledgement":"A.S. acknowledges funding from the Delta Institute for Theoretical Physics and the hospitality of the IBS Center for Theoretical Physics of Complex Systems, Daejeon, South Korea.

By dropping hydrogel spheres onto hot surfaces we find that, rather than hovering, they energetically bounce several times their diameter for minutes at a time. With high-speed video during a single impact, we uncover high-frequency microscopic gap dynamics at the sphere/substrate interface.

We consider the natural open question of derandomizing this result. We present a new deterministic fully dynamic algorithm that maintains a O(1)-approximate minimum vertex cover and maximum fractional matching, with an amortized update time of O(1). Previously, the best deterministic algorithm for this problem was due to Bhattacharya, Henzinger and Italiano [SODA 2015]; it had an approximation ratio of (2+ϵ) and an amortized update time of O(logn/ϵ2).

We analyse a network of centreline and lateral air temperature observations at Tsanteleina Glacier, Italy, during summer 2015. On average, VTGs are steep (&lt;−0.0065 °C m<jats:sup>−1</jats:sup>), but they are shallow under warm ambient conditions when the correlation between air temperature and elevation becomes weaker. Published along-flowline temperature distribution methods explain centreline observations well, including warming on the lower glacier tongue, but cannot estimate lateral temperature variability. Application of temperature distribution methods improves simulation of melt rates (RMSE) in an energy-balance model by up to 36% compared to the environmental lapse rate extrapolated from an off-glacier station. However, results suggest that model parameters are not easily transferable to glaciers with a small fetch without recalibration. Such methods have potential to improve estimates of temperature across a glacier, but their parameter transferability should be further linked to the glacier and atmospheric characteristics. Furthermore, ‘cold spots’, which can be &gt;2°C cooler than expected for their elevation, whose occurrence is not predicted by the temperature distribution models, are identified at one-quarter of the measurement sites."}],"scopus_import":"1","type":"journal_article","publication_identifier":{"issn":["0022-1430"],"eissn":["1727-5652"]},"citation":{"ista":"SHAW TE, BROCK BW, AYALA Á, RUTTER N, Pellicciotti F. 2017.

Supraglacial ponds represent sinks within the discontinuous supraglacial drainage system, and occasionally drain englacially. To assess pond dynamics, we made pond water level measurements on Lirung Glacier, Nepal, during May and October of 2013 and 2014. Simultaneously, aerial, satellite, and terrestrial orthoimages and digital elevation models were obtained, providing snapshots of the ponds and their surroundings. We performed a DEM-based analysis of the glacier's closed surface catchments to identify surface drainage pathways and englacial drainage points, and compared this to field observations of surface and near-surface water flow. The total ponded area was higher in the pre-monsoon than post-monsoon, with individual ponds filling and draining seasonally associated with the surface exposure of englacial conduit segments. We recorded four pond drainage events, all of which occurred gradually (duration of weeks), observed diurnal fluctuations indicative of varying water supply and outflow discharge, and we documented instances of interaction between distant ponds. The DEM drainage analysis identified numerous sinks >3 m in depth across the glacier surface, few of which exhibited ponds (23%), while the field survey highlighted instances of surface water only explicable via englacial routes. Taken together, our observations provide evidence for widespread supraglacial-englacial connectivity of meltwater drainage paths. Results suggest that successive englacial conduit collapse events, themselves likely driven by supraglacial pond drainage, cause the glacier surface drainage system to evolve into a configuration following relict englacial conduit systems. Within this system, ponds form in depressions of reduced drainage efficiency and link the supraglacial and englacial drainage networks."}],"type":"journal_article","_id":"12610","quality_controlled":"1","publication_status":"published"},{"publication_status":"published","type":"journal_article","abstract":[{"lang":"eng","text":"We investigate the energy balance and ablation regimes of glaciers in high-elevation, dry environments using glaciometeorological data collected on six glaciers in the semiarid Andes of North-Central Chile (29–34°S, 3127–5324 m). We use a point-scale physically based energy balance (EB) model and an enhanced Temperature-Index (ETI) model that calculates melt rates only as a function of air temperature and net shortwave radiation. At all sites, the largest energy inputs are net shortwave and incoming longwave radiation, which are controlled by surface albedo and elevation, respectively. Turbulent fluxes cancel each other out at the lower sites, but as elevation increases, cold, dry and wind-exposed conditions increase the magnitude of negative latent heat fluxes, associated with large surface sublimation rates. In midsummer (January), ablation rates vary from 67.9 mm w.e. d−1 at the lowest site (∼100% corresponding to melt), to 2.3 mm w.e. d−1 at the highest site (>85% corresponding to surface sublimation). At low-elevation, low-albedo, melt-dominated sites, the ETI model correctly reproduces melt using a large range of possible parameters, but both the performance and parameter transferability decrease with elevation for two main reasons: (i) the air temperature threshold approach for melt onset does not capture the diurnal variability of melt in cold and strong irradiated environments and (ii) energy losses decrease the correlation between melt and net shortwave radiation. We summarize our results by means of an elevation profile of ablation components that can be used as reference in future studies of glacier ablation in the semiarid Andes."}],"scopus_import":"1","citation":{"mla":"Ayala, A., et al. “Patterns of Glacier Ablation across North-Central Chile: Identifying the Limits of Empirical Melt Models under Sublimation-Favorable Conditions.” <i>Water Resources Research</i>, vol. 53, no. 7, American Geophysical Union, 2017, pp. 5601–25, doi:<a href=\"https://doi.org/10.1002/2016wr020126\">10.1002/2016wr020126</a>.","apa":"Ayala, A., Pellicciotti, F., MacDonell, S., McPhee, J., &#38; Burlando, P.

We analyse 172 Landsat TM/ETM+ scenes for the period 1999–2013 to identify thawed supraglacial ponds for the debris-covered tongues of five glaciers in the Langtang Valley of Nepal. We apply an advanced atmospheric correction routine (Landcor/6S) and use band ratio and image morphological techniques to identify ponds and validate our results with 2.5 m Cartosat-1 observations. We then characterize the spatial, seasonal and interannual patterns of ponds. We find high variability in pond incidence between glaciers (May–October means of 0.08–1.69% of debris area), with ponds most frequent in zones of low surface gradient and velocity. The ponds show pronounced seasonality, appearing in the pre-monsoon as snow melts, peaking at the monsoon onset at 2% of debris-covered area, then declining in the post-monsoon as ponds drain or freeze. Ponds are highly recurrent and persistent, with 40.5% of pond locations occurring for multiple years. Rather than a trend in pond cover over the study period, we find high interannual variability for each glacier after controlling for seasonality.","lang":"eng"}],"_id":"12612","quality_controlled":"1","publication_status":"published","intvolume":"        63","month":"02","date_published":"2017-02-01T00:00:00Z","date_updated":"2023-02-24T11:38:31Z","keyword":["Earth-Surface Processes"],"issue":"237","oa":1,"page":"88-105","year":"2017","volume":63,"date_created":"2023-02-20T08:14:16Z","day":"01","status":"public","main_file_link":[{"url":"https://doi.org/10.1017/jog.2016.120","open_access":"1"}],"doi":"10.1017/jog.2016.120","publication":"Journal of Glaciology","oa_version":"Published Version"},{"date_updated":"2023-05-16T07:22:23Z","oa":1,"title":"Scientific Computing at IST Austria","author":[{"last_name":"Schlögl","orcid":"0000-0002-5621-8100","id":"45BF87EE-F248-11E8-B48F-1D18A9856A87","first_name":"Alois","full_name":"Schlögl, Alois"},{"first_name":"Janos","id":"3D3A06F8-F248-11E8-B48F-1D18A9856A87","last_name":"Kiss","full_name":"Kiss, Janos"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"success":1,"file_name":"2017_AHPC_Schloegl.pdf","date_updated":"2023-05-16T07:20:50Z","date_created":"2023-05-16T07:20:50Z","content_type":"application/pdf","file_id":"12969","creator":"dernst","file_size":1005486,"relation":"main_file","checksum":"7bcc499479d4f4c5ce6c0071c24ca6c6","access_level":"open_access"}],"date_published":"2017-03-03T00:00:00Z","month":"03","has_accepted_license":"1","publisher":"FSP Scientific Computing","language":[{"iso":"eng"}],"year":"2017","article_processing_charge":"No","page":"28","department":[{"_id":"ScienComp"}],"conference":{"location":"Grundlsee, Austria","name":"AHPC: Austrian HPC Meeting","start_date":"2017-03-01","end_date":"2017-03-03"},"_id":"12905","ddc":["000"],"date_created":"2023-05-05T12:58:53Z","day":"03","status":"public","citation":{"chicago":"Schlögl, Alois, and Janos Kiss. “Scientific Computing at IST Austria.” In <i>AHPC17 – Austrian HPC Meeting 2017</i>, 28.

Ureteric bud growth and branching requires GDNF signaling from the surrounding mesenchyme to cells at the ureteric bud tips, via the Ret receptor tyrosine kinase and coreceptor Gfrα1; Ret signaling up-regulates transcription factors Etv4 and Etv5, which are also critical for branching. Despite extensive knowledge of the genetic control of these events, it is not understood, at the cellular level, how renal branching morphogenesis is achieved or how Ret signaling influences epithelial cell behaviors to promote this process. Analysis of chimeric embryos previously suggested a role for Ret signaling in promoting cell rearrangements in the nephric duct, but this method was unsuited to study individual cell behaviors during ureteric bud branching. Here, we use Mosaic Analysis with Double Markers (MADM), combined with organ culture and time-lapse imaging, to trace the movements and divisions of individual ureteric bud tip cells. We first examine wild-type clones and then Ret or Etv4 mutant/wild-type clones in which the mutant and wild-type sister cells are differentially and heritably marked by green and red fluorescent proteins. We find that, in normal kidneys, most individual tip cells behave as self-renewing progenitors, some of whose progeny remain at the tips while others populate the growing UB trunks. In Ret or Etv4 MADM clones, the wild-type cells generated at a UB tip are much more likely to remain at, or move to, the new tips during branching and elongation, while their Ret−/− or Etv4−/− sister cells tend to lag behind and contribute only to the trunks. By tracking successive mitoses in a cell lineage, we find that Ret signaling has little effect on proliferation, in contrast to its effects on cell movement. Our results show that Ret/Etv4 signaling promotes directed cell movements in the ureteric bud tips, and suggest a model in which these cell movements mediate branching morphogenesis.","lang":"eng"}],"date_created":"2021-07-23T09:39:34Z","_id":"9707","day":"14","status":"public"},{"date_created":"2021-07-23T11:34:34Z","_id":"9709","day":"18","status":"public","citation":{"ama":"Prentice J, Marre O, Ioffe M, Loback A, Tkačik G, Berry M.

A hypothesis about this structure is that these collective activity patterns function as population codewords–collective modes–carrying information distinct from that of any single cell. We investigate this phenomenon in recordings of ∼150 retinal ganglion cells, the retina’s output. We develop a novel statistical model that decomposes the population response into modes; it predicts the distribution of spiking activity in the ganglion cell population with high accuracy. We found that the modes represent localized features of the visual stimulus that are distinct from the features represented by single neurons. Modes form clusters of activity states that are readily discriminated from one another. When we repeated the same visual stimulus, we found that the same mode was robustly elicited. These results suggest that retinal ganglion cells’ collective signaling is endowed with a form of error-correcting code–a principle that may hold in brain areas beyond retina."}],"type":"research_data_reference","related_material":{"record":[{"id":"1197","relation":"used_in_publication","status":"public"}]},"oa_version":"Published Version","main_file_link":[{"open_access":"1","url":"https://doi.org/10.5061/dryad.1f1rc"}],"doi":"10.5061/dryad.1f1rc","date_updated":"2023-02-21T16:34:41Z","oa":1,"title":"Data from: Error-robust modes of the retinal population code","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","author":[{"first_name":"Jason","last_name":"Prentice","full_name":"Prentice, Jason"},{"first_name":"Olivier","last_name":"Marre","full_name":"Marre, Olivier"},{"last_name":"Ioffe","first_name":"Mark","full_name":"Ioffe, Mark"},{"last_name":"Loback","first_name":"Adrianna","full_name":"Loback, Adrianna"},{"last_name":"Tkačik","orcid":"0000-0002-6699-1455","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","first_name":"Gašper","full_name":"Tkačik, Gašper"},{"last_name":"Berry","first_name":"Michael","full_name":"Berry, Michael"}],"date_published":"2017-10-18T00:00:00Z","month":"10","publisher":"Dryad","year":"2017","article_processing_charge":"No","department":[{"_id":"GaTk"}]},{"citation":{"chicago":"Etheridge, Alison, and Nicholas H Barton. “Data for: Establishment in a New Habitat by Polygenic Adaptation.” Mendeley Data, 2017. <a href=\"https://doi.org/10.17632/nw68fxzjpm.1\">https://doi.org/10.17632/nw68fxzjpm.1</a>.","ama":"Etheridge A, Barton NH.
