The differential susceptibility dM/dB, however, is more rapidly suppressed for B≳16 T than expected from the properties of the low field superconducting state, and saturates at a low value for fields B≳24 T. In addition, torque measurements on a p=0.11 YBCO crystal in pulsed field up to 65 T and temperatures down to 8 K show similar behavior, with no additional features at higher fields. We offer two candidate scenarios to explain these observations: (a) superconductivity survives but is heavily suppressed at high field by competition with charge-density-wave (CDW) order; (b) static superconductivity disappears near 24 T and is followed by a region of fluctuating superconductivity, which causes dM/dB to saturate at high field. The diamagnetic signal observed above 50 T for the p=0.11 crystal at 40 K and below may be caused by changes in the normal state susceptibility rather than bulk or fluctuating superconductivity. There will be orbital (Landau) diamagnetism from electron pockets and possibly a reduction in spin susceptibility caused by the stronger three-dimensional ordered CDW."}],"volume":92,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"APS","date_updated":"2021-01-12T08:11:42Z","publication_identifier":{"issn":["1098-0121","1550-235X"]},"date_created":"2019-11-19T13:22:06Z","author":[{"first_name":"Jing Fei","last_name":"Yu","full_name":"Yu, Jing Fei"},{"first_name":"B.

We report here on the synthesis and self-assembly of aggregate-free, single-crystalline titanium-based perovskite nanoparticles with controlled morphology and surface composition by using a simple, easily scalable and highly versatile colloidal route. Single-crystalline, non-aggregated BaTiO3 colloidal nanocrystals, used as a model system, have been prepared under solvothermal conditions at temperatures as low as 180 °C. The shape of the nanocrystals was tuned from spheroidal to cubic upon changing the polarity of the solvent, whereas their size was varied from 16 to 30 nm for spheres and 5 to 78 nm for cubes by changing the concentration of the precursors and the reaction time, respectively. The hydrophobic, oleic acid-passivated nanoparticles exhibit very good solubility in non-polar solvents and can be rendered dispersible in polar solvents by a simple process involving the oxidative cleavage of the double bond upon treating the nanopowders with the Lemieux–von Rudloff reagent. Lattice dynamic analysis indicated that regardless of their size, BaTiO3 nanocrystals present local disorder within the perovskite unit cell, associated with the existence of polar ordering. We also demonstrate for the first time that, in addition to being used for fabricating large area, crack-free, highly uniform films, BaTiO3 nanocubes can serve as building blocks for the design of 2D and 3D mesoscale structures, such as superlattices and superparticles. Interestingly, the type of superlattice structure (simple cubic or face centered cubic) appears to be determined by the type of solvent in which the nanocrystals were dispersed. This approach provides an excellent platform for the synthesis of other titanium-based perovskite colloidal nanocrystals with controlled chemical composition, surface structure and morphology and for their assembly into complex architectures, therefore opening the door for the design of novel mesoscale functional materials/nanocomposites with potential applications in energy conversion, data storage and the biomedical field."}],"oa_version":"None","external_id":{"pmid":["26168304"]},"pmid":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":7,"language":[{"iso":"eng"}],"article_type":"original","article_processing_charge":"No","status":"public","date_published":"2015-08-14T00:00:00Z","title":"Solvothermal synthesis and controlled self-assembly of monodisperse titanium-based perovskite colloidal nanocrystals","extern":"1","month":"08","intvolume":"         7","_id":"7456","year":"2015","type":"journal_article","publication_status":"published","quality_controlled":"1","publication":"Nanoscale","publisher":"RSC","page":"12955-12969","doi":"10.1039/c5nr00737b","issue":"30","citation":{"mla":"Caruntu, Daniela, et al. “Solvothermal Synthesis and Controlled Self-Assembly of Monodisperse Titanium-Based Perovskite Colloidal Nanocrystals.” <i>Nanoscale</i>, vol. 7, no. 30, RSC, 2015, pp. 12955–69, doi:<a href=\"https://doi.org/10.1039/c5nr00737b\">10.1039/c5nr00737b</a>.","chicago":"Caruntu, Daniela, Taha Rostamzadeh, Tommaso Costanzo, Saman Salemizadeh Parizi, and Gabriel Caruntu. “Solvothermal Synthesis and Controlled Self-Assembly of Monodisperse Titanium-Based Perovskite Colloidal Nanocrystals.” <i>Nanoscale</i>.

We study the distribution of matrix elements of a local operator between the system's eigenstates, finding a qualitatively different behavior in the manybody localized (MBL) and ergodic phases. To characterize how strongly a local perturbation modifies the eigenstates, we introduce the parameter g(L) = (In (Vnm/δ)) which represents the disorder-averaged ratio of a typical matrix element of a local operator V to energy level spacing δ this parameter is reminiscent of the Thouless conductance in the single-particle localization. We show that the parameter g(L) decreases with system size L in the MBL phase and grows in the ergodic phase. We surmise that the delocalization transition occurs when g(L) is independent of system size, g(L)=gc ~ 1. We illustrate our approach by studying the many-body localization transition and resolving the many-body mobility edge in a disordered one-dimensional XXZ spin-1=2 chain using exact diagonalization and time-evolving block-decimation methods. Our criterion for the MBL transition gives insights into microscopic details of transition. Its direct physical consequences, in particular, logarithmically slow transport at the transition and extensive entanglement entropy of the eigenstates, are consistent with recent renormalization-group predictions.","lang":"eng"}],"publication":"Physical Review X","publisher":"American Physical Society","oa":1,"volume":5},{"_id":"99","year":"2015","intvolume":"        11","extern":"1","month":"09","title":"Parity lifetime of bound states in a proximitized semiconductor nanowire","date_published":"2015-09-14T00:00:00Z","status":"public","language":[{"iso":"eng"}],"volume":11,"oa":1,"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","external_id":{"arxiv":["1501.05155"]},"oa_version":"Preprint","arxiv":1,"abstract":[{"lang":"eng","text":"Quasiparticle excitations can compromise the performance of superconducting devices, causing high-frequency dissipation, decoherence in Josephson qubits, and braiding errors in proposed Majorana-based topological quantum computers.

The procedure takes advantage of a ligand displacement step to incorporate controlled concentrations of halide ions while removing carboxylic acids from the NP surface. Upon consolidation of the NPs into dense pellets, halide ions diffuse within the crystal structure, doping the anion sublattice and achieving n-type electrical doping. Through the characterization of the thermoelectric properties of nanocrystalline PbS, we demonstrate this strategy to be effective to control charge transport properties on thermoelectric nanomaterials assembled from NP building blocks. This approach is subsequently extended to PbTexSe1-x@PbS core-shell NPs, where a significant enhancement of the thermoelectric figure of merit is achieved.

In this regard, up to a 15-fold increase of the photocatalytic hydrogen evolution activity was obtained with CZTS–PtCo when compared with CZTS. Furthermore, two times higher hydrogen evolution rates were obtained for CZTS–PtCo when compared with CZTS–Pt, in spite of the lower precious metal loading of the former.

Above the antiferromagnetic ordering temperature (TN) the system response is due to both Hubbard excitons (HE) and their constituent unpaired SE. The SE response becomes strongly suppressed immediately below TN. We argue that this increase in binding energy is due to a unique interplay between the frustrated Kitaev and the weak Heisenberg-type ordering term in the Hamiltonian, mediating an effective interaction between the spin-singlet SE. This interaction grows with distance causing the SE to become trapped in the HE, similar to quark confinement inside hadrons. This binding of charged particles, induced by magnetic ordering, is a result of a confinement-deconfinement transition of spin excitations. This observation provides evidence for spin liquid type behavior which is expected in Na2IrO3."}],"publication":"Physical Review Letters","oa_version":"Published Version","publisher":"American Physical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":114,"oa":1},{"publication":"arXiv","abstract":[{"text":"We study conditions under which a finite simplicial complex $K$ can be mapped to $\\mathbb R^d$ without higher-multiplicity intersections. An almost $r$-embedding is a map $f: K\\to \\mathbb R^d$ such that the images of any $r$\r\npairwise disjoint simplices of $K$ do not have a common point. We show that if $r$ is not a prime power and $d\\geq 2r+1$, then there is a counterexample to the topological Tverberg conjecture, i.e., there is an almost $r$-embedding of\r\nthe $(d+1)(r-1)$-simplex in $\\mathbb R^d$. This improves on previous constructions of counterexamples (for $d\\geq 3r$) based on a series of papers by M. \\\"Ozaydin, M. Gromov, P. Blagojevi\\'c, F. Frick, G. Ziegler, and the second and fourth present authors. The counterexamples are obtained by proving the following algebraic criterion in codimension 2: If $r\\ge3$ and if $K$ is a finite $2(r-1)$-complex then there exists an almost $r$-embedding $K\\to \\mathbb R^{2r}$ if and only if there exists a general position PL map $f:K\\to \\mathbb R^{2r}$ such that the algebraic intersection number of the $f$-images of any $r$ pairwise disjoint simplices of $K$ is zero. This result can be restated in terms of cohomological obstructions or equivariant maps, and extends an analogous codimension 3 criterion by the second and fourth authors. As another application we classify ornaments $f:S^3 \\sqcup S^3\\sqcup S^3\\to \\mathbb R^5$ up to ornament\r\nconcordance. It follows from work of M. Freedman, V. Krushkal and P.

These models, however, neglect regulatory crosstalk: the possibility that noncognate TFs could initiate transcription, with potentially disastrous effects for the cell. Here, we estimate the importance of crosstalk, suggest that its avoidance strongly constrains equilibrium models of TF binding, and propose an alternative nonequilibrium scheme that implements kinetic proofreading to suppress erroneous initiation. This proposal is consistent with the observed covalent modifications of the transcriptional apparatus and predicts increased noise in gene expression as a trade-off for improved specificity. Using information theory, we quantify this trade-off to find when optimal proofreading architectures are favored over their equilibrium counterparts. Such architectures exhibit significant super-Poisson noise at low expression in steady state."}],"volume":115,"oa":1,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","external_id":{"arxiv":["1504.05716"],"isi":["000366106700014"]},"date_updated":"2026-04-08T13:55:46Z","author":[{"last_name":"Cepeda Humerez","first_name":"Sarah A","id":"3DEE19A4-F248-11E8-B48F-1D18A9856A87","full_name":"Cepeda Humerez, Sarah A"},{"id":"34DA8BD6-F248-11E8-B48F-1D18A9856A87","first_name":"Georg","last_name":"Rieckh","full_name":"Rieckh, Georg"},{"full_name":"Tkacik, Gasper","orcid":"0000-0002-6699-1455","last_name":"Tkacik","first_name":"Gasper","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87"}],"date_created":"2018-12-11T11:52:49Z","project":[{"name":"Limits to selection in biology and in evolutionary computation","grant_number":"250152","call_identifier":"FP7","_id":"25B07788-B435-11E9-9278-68D0E5697425"}],"doi":"10.1103/PhysRevLett.115.248101","issue":"24","article_number":"248101","citation":{"apa":"Cepeda Humerez, S.

In this review, we provide an overview of the multiple developmental roles of PIN proteins, including the atypical endoplasmic reticulum-localized members of the family, and look at the family from an evolutionary perspective. Next, we cover the cell biological and molecular aspects of PIN function, in particular the establishment of their polar subcellular localization.

The algorithmic problem given a graph and a quantitative property asks to compute the optimal value (the infimum value over all traces) from every node of the graph. We consider graphs with constant treewidth, and it is well-known that the control-flow graphs of most programs have constant treewidth. Let n denote the number of nodes of a graph, m the number of edges (for constant treewidth graphs m=O(n)) and W the largest absolute value of the weights. Our main theoretical results are as follows. First, for constant treewidth graphs we present an algorithm that approximates the mean-payoff value within a multiplicative factor of ϵ in time O(n⋅log(n/ϵ)) and linear space, as compared to the classical algorithms that require quadratic time. Second, for the ratio property we present an algorithm that for constant treewidth graphs works in time O(n⋅log(|a⋅b|))=O(n⋅log(n⋅W)), when the output is ab, as compared to the previously best known algorithm with running time O(n2⋅log(n⋅W)). Third, for the minimum initial credit problem we show that (i) for general graphs the problem can be solved in O(n2⋅m) time and the associated decision problem can be solved in O(n⋅m) time, improving the previous known O(n3⋅m⋅log(n⋅W)) and O(n2⋅m) bounds, respectively; and (ii) for constant treewidth graphs we present an algorithm that requires O(n⋅logn) time, improving the previous known O(n4⋅log(n⋅W)) bound. We have implemented some of our algorithms and show that they present a significant speedup on standard benchmarks.","lang":"eng"}],"author":[{"orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","last_name":"Chatterjee"},{"full_name":"Ibsen-Jensen, Rasmus","orcid":"0000-0003-4783-0389","id":"3B699956-F248-11E8-B48F-1D18A9856A87","last_name":"Ibsen-Jensen","first_name":"Rasmus"},{"id":"49704004-F248-11E8-B48F-1D18A9856A87","last_name":"Pavlogiannis","first_name":"Andreas","full_name":"Pavlogiannis, Andreas","orcid":"0000-0002-8943-0722"}],"date_created":"2018-12-11T11:52:59Z","project":[{"grant_number":"P 23499-N23","name":"Modern Graph Algorithmic Techniques in Formal Verification","call_identifier":"FWF","_id":"2584A770-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","_id":"25832EC2-B435-11E9-9278-68D0E5697425","name":"Rigorous Systems Engineering","grant_number":"S 11407_N23"},{"name":"Quantitative Graph Games: Theory and Applications","grant_number":"279307","_id":"2581B60A-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"},{"name":"Microsoft Research Faculty Fellowship","_id":"2587B514-B435-11E9-9278-68D0E5697425"}],"date_updated":"2026-04-08T14:22:16Z","_id":"1607","year":"2015","intvolume":"      9206","title":"Faster algorithms for quantitative verification in constant treewidth graphs","scopus_import":"1","month":"07","date_published":"2015-07-16T00:00:00Z","ec_funded":1,"status":"public","article_processing_charge":"No","language":[{"iso":"eng"}],"related_material":{"record":[{"status":"public","id":"5430","relation":"earlier_version"},{"relation":"earlier_version","id":"5437","status":"public"},{"relation":"dissertation_contains","status":"public","id":"821"}]},"publisher":"Springer","quality_controlled":"1","type":"conference","publication_status":"published","alternative_title":["LNCS"],"corr_author":"1","department":[{"_id":"KrCh"}],"main_file_link":[{"url":"http://arxiv.org/abs/1504.07384","open_access":"1"}],"citation":{"ieee":"K.

We consider a general framework with RSMs where the transitions are labeled from a semiring, and path properties are algebraic with semiring operations. RSMs with algebraic path properties can model interprocedural dataflow analysis problems, the shortest path problem, the most probable path problem, etc. The traditional algorithms for interprocedural analysis focus on path properties where the starting point is fixed as the entry point of a specific method. In this work, we consider possible multiple queries as required in many applications such as in alias analysis. The study of multiple queries allows us to bring in a very important algorithmic distinction between the resource usage of the one-time preprocessing vs for each individual query. The second aspect that we consider is that the control flow graphs for most programs have constant treewidth. Our main contributions are simple and implementable algorithms that supportmultiple queries for algebraic path properties for RSMs that have constant treewidth. Our theoretical results show that our algorithms have small additional one-time preprocessing, but can answer subsequent queries significantly faster as compared to the current best-known solutions for several important problems, such as interprocedural reachability and shortest path. We provide a prototype implementation for interprocedural reachability and intraprocedural shortest path that gives a significant speed-up on several benchmarks.","lang":"eng"}],"oa_version":"Preprint","arxiv":1,"external_id":{"arxiv":["1410.7724"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"volume":50,"conference":{"start_date":"2015-01-15","end_date":"2015-01-17","name":"SIGPLAN: Symposium on Principles of Programming Languages","location":"Mumbai, India"},"page":"97 - 109","acknowledgement":"We thank anonymous reviewers for helpful comments to improve the presentation of the paper.","doi":"10.1145/2676726.2676979","issue":"1","citation":{"ieee":"K.

The input consists of an ICFG, a positive weight function that assigns every transition a positive integer-valued number, and a labelling of the transitions (events) as good, bad, and neutral events. The weight function assigns to each transition a numerical value that represents ameasure of how good or bad an event is. The quantitative analysis problem asks whether there is a run of the ICFG where the ratio of the sum of the numerical weights of good events versus the sum of weights of bad events in the long-run is at least a given threshold (or equivalently, to compute the maximal ratio among all valid paths in the ICFG). The quantitative analysis problem for ICFGs can be solved in polynomial time, and we present an efficient and practical algorithm for the problem. We show that several problems relevant for static program analysis, such as estimating the worst-case execution time of a program or the average energy consumption of a mobile application, can be modeled in our framework. We have implemented our algorithm as a tool in the Java Soot framework. We demonstrate the effectiveness of our approach with two case studies. First, we show that our framework provides a sound approach (no false positives) for the analysis of inefficiently-used containers. Second, we show that our approach can also be used for static profiling of programs which reasons about methods that are frequently invoked. Our experimental results show that our tool scales to relatively large benchmarks, and discovers relevant and useful information that can be used to optimize performance of the programs.","lang":"eng"}],"oa_version":"None","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":50},{"quality_controlled":"1","publication_status":"published","type":"conference","department":[{"_id":"KrCh"}],"related_material":{"record":[{"relation":"earlier_version","status":"public","id":"5423"},{"relation":"dissertation_contains","status":"public","id":"821"}]},"publisher":"IEEE","publication":"Real-Time Systems Symposium","conference":{"start_date":"2014-12-02","name":"RTSS: Real-Time Systems Symposium","end_date":"2014-12-05","location":"Rome, Italy"},"page":"118 - 127","day":"15","isi":1,"publist_id":"5417","citation":{"short":"K.

A clairvoyant scheduler. We demonstrate the flexibility and power of our approach by comparing the competitive ratio of several on-line algorithms, including Dover, that have been proposed in the past, for various task sets. Our experimental results reveal that none of these algorithms is universally optimal, in the sense that there are task sets where other schedulers provide better performance. Our framework is hence a very useful design tool for selecting optimal algorithms for a given application.","lang":"eng"}],"status":"public","article_processing_charge":"No","language":[{"iso":"eng"}],"year":"2015","_id":"1714","intvolume":"      2015","scopus_import":"1","month":"01","title":"A framework for automated competitive analysis of on-line scheduling of firm-deadline tasks","date_published":"2015-01-15T00:00:00Z"},{"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","external_id":{"isi":["000349208800011"]},"oa":1,"volume":160,"abstract":[{"text":"3D amoeboid cell migration is central to many developmental and disease-related processes such as cancer metastasis. Here, we identify a unique prototypic amoeboid cell migration mode in early zebrafish embryos, termed stable-bleb migration. Stable-bleb cells display an invariant polarized balloon-like shape with exceptional migration speed and persistence. Progenitor cells can be reversibly transformed into stable-bleb cells irrespective of their primary fate and motile characteristics by increasing myosin II activity through biochemical or mechanical stimuli. Using a combination of theory and experiments, we show that, in stable-bleb cells, cortical contractility fluctuations trigger a stochastic switch into amoeboid motility, and a positive feedback between cortical flows and gradients in contractility maintains stable-bleb cell polarization. We further show that rearward cortical flows drive stable-bleb cell migration in various adhesive and non-adhesive environments, unraveling a highly versatile amoeboid migration phenotype.","lang":"eng"}],"oa_version":"Published Version","project":[{"grant_number":"T 560-B17","name":"Cell- and Tissue Mechanics in Zebrafish Germ Layer Formation","_id":"2529486C-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"name":"Cell Cortex and Germ Layer Formation in Zebrafish Gastrulation","grant_number":"I812-B12","_id":"2527D5CC-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"}],"date_created":"2018-12-11T11:52:35Z","author":[{"full_name":"Ruprecht, Verena","orcid":"0000-0003-4088-8633","last_name":"Ruprecht","first_name":"Verena","id":"4D71A03A-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0002-2670-2217","full_name":"Wieser, Stefan","first_name":"Stefan","last_name":"Wieser","id":"355AA5A0-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Andrew","last_name":"Callan Jones","full_name":"Callan Jones, Andrew"},{"full_name":"Smutny, Michael","orcid":"0000-0002-5920-9090","last_name":"Smutny","first_name":"Michael","id":"3FE6E4E8-F248-11E8-B48F-1D18A9856A87"},{"id":"4C6E54C6-F248-11E8-B48F-1D18A9856A87","last_name":"Morita","first_name":"Hitoshi","full_name":"Morita, Hitoshi"},{"orcid":"0000-0002-6453-8075","full_name":"Sako, Keisuke","first_name":"Keisuke","last_name":"Sako","id":"3BED66BE-F248-11E8-B48F-1D18A9856A87"},{"id":"419EECCC-F248-11E8-B48F-1D18A9856A87","first_name":"Vanessa","last_name":"Barone","orcid":"0000-0003-2676-3367","full_name":"Barone, Vanessa"},{"full_name":"Ritsch Marte, Monika","first_name":"Monika","last_name":"Ritsch Marte"},{"orcid":"0000-0002-6620-9179","full_name":"Sixt, Michael K","first_name":"Michael K","last_name":"Sixt","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Raphaël","last_name":"Voituriez","full_name":"Voituriez, Raphaël"},{"orcid":"0000-0002-0912-4566","full_name":"Heisenberg, Carl-Philipp J","id":"39427864-F248-11E8-B48F-1D18A9856A87","first_name":"Carl-Philipp J","last_name":"Heisenberg"}],"date_updated":"2026-04-08T14:22:39Z","intvolume":"       160","year":"2015","_id":"1537","pubrep_id":"484","date_published":"2015-02-12T00:00:00Z","scopus_import":"1","month":"02","title":"Cortical contractility triggers a stochastic switch to fast amoeboid cell motility","status":"public","language":[{"iso":"eng"}],"article_processing_charge":"No","publisher":"Cell Press","related_material":{"record":[{"status":"public","id":"961","relation":"dissertation_contains"}]},"has_accepted_license":"1","ddc":["570"],"publication":"Cell","publication_status":"published","type":"journal_article","quality_controlled":"1","department":[{"_id":"CaHe"},{"_id":"MiSi"}],"file":[{"access_level":"open_access","checksum":"228d3edf40627d897b3875088a0ac51f","creator":"system","file_name":"IST-2016-484-v1+1_1-s2.0-S0092867415000094-main.pdf","date_updated":"2020-07-14T12:45:01Z","date_created":"2018-12-12T10:13:21Z","relation":"main_file","file_size":4362653,"content_type":"application/pdf","file_id":"5003"}],"corr_author":"1","day":"12","isi":1,"publist_id":"5634","citation":{"ama":"Ruprecht V, Wieser S, Callan Jones A, et al.
