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."}]},{"abstract":[{"lang":"eng","text":"The rational design of monodisperse ferroelectric nanocrystals with controlled size and shape and their organization into hierarchical structures has been a critical step for understanding the polar ordering in nanoscale ferroelectrics, as well as the design of nanocrystal-based functional materials which harness the properties of individual nanoparticles and the collective interactions between them. 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."}],"title":"Solvothermal synthesis and controlled self-assembly of monodisperse titanium-based perovskite colloidal nanocrystals","date_published":"2015-08-14T00:00:00Z","date_updated":"2023-02-23T13:08:24Z","publication_identifier":{"issn":["2040-3364","2040-3372"]},"doi":"10.1039/c5nr00737b","language":[{"iso":"eng"}],"extern":"1","publication":"Nanoscale","publication_status":"published","pmid":1,"_id":"7456","article_processing_charge":"No","type":"journal_article","page":"12955-12969","date_created":"2020-02-05T14:16:37Z","issue":"30","intvolume":"         7","article_type":"original","day":"14","status":"public","publisher":"RSC","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>.","short":"D.

Na-ion cathodes, FeS2 NCs in the present study, may serve as attractive alternatives to Mg-ion cathodes due to the higher voltage of operation and fast, highly reversible insertion of Na-ions. In this proof-of-concept study, electrochemical cycling of the Na/Mg hybrid battery was characterized by high rate capability, high Coulombic efficiency of 99.8%, and high energy density. In particular, with an average discharge voltage of ∼1.1 V and a cathodic capacity of 189 mAh g-1 at a current of 200 mA g-1, the presented Mg/FeS2 hybrid battery delivers energy densities of up to 210 Wh kg-1, comparable to commercial Li-ion batteries and approximately twice as high as state-of-the-art Mg-ion batteries based on Mo6S8 cathodes. Further significant gains in the energy density are expected from the development of Na/Mg electrolytes with a broader electrochemical stability window.

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.

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.","lang":"eng"}],"doi":"10.1103/PhysRevLett.114.017203","status":"public","publisher":"American Physical Society","date_updated":"2021-01-12T07:52:54Z","publication_status":"published","citation":{"short":"Z.

Here we quantify the Shh gradient in the developing mouse neural tube and show that while the amplitude of the gradient increases over time, the activity of the pathway transcriptional effectors, Gli proteins, initially increases but later decreases. Computational analysis of the pathway suggests three mechanisms that could contribute to this adaptation: transcriptional upregulation of the inhibitory receptor Ptch1, transcriptional downregulation of Gli and the differential stability of active and inactive Gli isoforms. Consistent with this, Gli2 protein expression is downregulated during neural tube patterning and adaptation continues when the pathway is stimulated downstream of Ptch1. Moreover, the Shh-induced upregulation of Gli2 transcription prevents Gli activity levels from adapting in a different cell type, NIH3T3 fibroblasts, despite the upregulation of Ptch1. Multiple mechanisms therefore contribute to the intracellular dynamics of Shh signalling, resulting in different signalling dynamics in different cell types.","lang":"eng"}],"license":"https://creativecommons.org/licenses/by/4.0/","title":"Ptch1 and Gli regulate Shh signalling dynamics via multiple mechanisms","date_published":"2015-04-02T00:00:00Z","date_updated":"2026-05-19T09:52:55Z","publication_identifier":{"eissn":["2041-1723"]},"doi":"10.1038/ncomms7709"},{"doi":"10.1007/978-3-319-21668-3_11","date_updated":"2026-04-09T10:54:00Z","title":"From non-preemptive to preemptive scheduling using synchronization synthesis","date_published":"2015-07-01T00:00:00Z","abstract":[{"lang":"eng","text":"We present a computer-aided programming approach to concurrency.

The specification requires that any such sequence produced under a preemptive scheduler should be included in the set of such sequences produced under a non-preemptive scheduler. The solution is based on a finitary abstraction, an algorithm for bounded language inclusion modulo an independence relation, and rules for inserting synchronization. We apply the approach to device-driver programming, where the driver threads call the software interface of the device and the API provided by the operating system.

We provide bounds for several instances of this question, for the minimum length of topologically non-trivial closed curves, pants decompositions, and cut graphs with a given combinatorial map in triangulated combinatorial surfaces (or their dual cross-metric counterpart). Our work builds upon Riemannian systolic inequalities, which bound the minimum length of non-trivial closed curves in terms of the genus and the area of the surface. We first describe a systematic way to translate Riemannian systolic inequalities to a discrete setting, and vice-versa. This implies a conjecture by Przytycka and Przytycki (Graph structure theory. Contemporary Mathematics, vol. 147, 1993), a number of new systolic inequalities in the discrete setting, and the fact that a theorem of Hutchinson on the edge-width of triangulated surfaces and Gromov’s systolic inequality for surfaces are essentially equivalent. We also discuss how these proofs generalize to higher dimensions. Then we focus on topological decompositions of surfaces. Relying on ideas of Buser, we prove the existence of pants decompositions of length O(g^(3/2)n^(1/2)) for any triangulated combinatorial surface of genus g with n triangles, and describe an O(gn)-time algorithm to compute such a decomposition. Finally, we consider the problem of embedding a cut graph (or more generally a cellular graph) with a given combinatorial map on a given surface. Using random triangulations, we prove (essentially) that, for any choice of a combinatorial map, there are some surfaces on which any cellular embedding with that combinatorial map has length superlinear in the number of triangles of the triangulated combinatorial surface. There is also a similar result for graphs embedded on polyhedral triangulations.","lang":"eng"}],"date_published":"2015-04-02T00:00:00Z","title":"Discrete systolic inequalities and decompositions of triangulated surfaces","date_updated":"2025-09-23T08:27:38Z","doi":"10.1007/s00454-015-9679-9"},{"language":[{"iso":"eng"}],"oa":1,"publication":"Information and Computation","publication_status":"published","main_file_link":[{"url":"http://arxiv.org/abs/1006.0673","open_access":"1"}],"abstract":[{"text":"We consider two-player zero-sum games on graphs.

On the basis of mode of interaction we have the following classification: (a) concurrent (both players interact simultaneously); and (b) turn-based (both players interact in turn). The two sources of randomness in these games are randomness in transition function and randomness in strategies. In general, randomized strategies are more powerful than deterministic strategies, and randomness in transitions gives more general classes of games. In this work we present a complete characterization for the classes of games where randomness is not helpful in: (a) the transition function probabilistic transition can be simulated by deterministic transition); and (b) strategies (pure strategies are as powerful as randomized strategies).

All temporal logic specifications in linear-time temporal logic (LTL) can be expressed as parity objectives. We study the qualitative analysis problem for POMDPs with parity objectives that asks whether there is a controller (policy) to ensure that the objective holds with probability 1 (almost-surely). While the qualitative analysis of POMDPs with parity objectives is undecidable, recent results show that when restricted to finite-memory policies the problem is EXPTIME-complete. While the problem is intractable in theory, we present a practical approach to solve the qualitative analysis problem. We designed several heuristics to deal with the exponential complexity, and have used our implementation on a number of well-known POMDP examples for robotics applications. Our results provide the first practical approach to solve the qualitative analysis of robot motion planning with LTL properties in the presence of uncertainty."}],"date_published":"2015-01-01T00:00:00Z","title":"Qualitative analysis of POMDPs with temporal logic specifications for robotics applications","main_file_link":[{"url":"http://arxiv.org/abs/1409.3360","open_access":"1"}],"language":[{"iso":"eng"}],"publication_status":"published","oa":1,"author":[{"last_name":"Chatterjee","first_name":"Krishnendu","orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"id":"3624234E-F248-11E8-B48F-1D18A9856A87","full_name":"Chmelik, Martin","first_name":"Martin","last_name":"Chmelik"},{"full_name":"Gupta, Raghav","last_name":"Gupta","first_name":"Raghav"},{"last_name":"Kanodia","first_name":"Ayush","full_name":"Kanodia, Ayush"}],"project":[{"_id":"2584A770-B435-11E9-9278-68D0E5697425","name":"Modern Graph Algorithmic Techniques in Formal Verification","grant_number":"P 23499-N23","call_identifier":"FWF"},{"call_identifier":"FWF","_id":"25863FF4-B435-11E9-9278-68D0E5697425","grant_number":"S11407","name":"Game Theory"},{"call_identifier":"FP7","_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications","grant_number":"279307"}],"quality_controlled":"1","oa_version":"Preprint","year":"2015","related_material":{"record":[{"status":"public","relation":"earlier_version","id":"5424"},{"id":"5426","relation":"earlier_version","status":"public"}]},"scopus_import":1,"status":"public","ec_funded":1,"publisher":"IEEE","day":"01","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","external_id":{"arxiv":["1409.3360"]},"conference":{"name":"ICRA: International Conference on Robotics and Automation","location":"Seattle, WA, United States","start_date":"2015-05-26","end_date":"2015-05-30"},"department":[{"_id":"KrCh"}],"month":"01","publist_id":"5394","citation":{"short":"K.

While significant progress has occurred over the last two decades, no single survey currently exists that discusses the similarities, differences, and practical considerations of the available appearance capture techniques as applied to human faces. A central difficulty of facial appearance capture is the way light interacts with skin-which has a complex multi-layered structure-and the interactions that occur below the skin surface can, by definition, only be observed indirectly. In this report, we distinguish between two broad strategies for dealing with this complexity. &quot;Image-based methods&quot; try to exhaustively capture the exact face appearance under different lighting and viewing conditions, and then render the face through weighted image combinations. &quot;Parametric methods&quot; instead fit the captured reflectance data to some parametric appearance model used during rendering, allowing for a more lightweight and flexible representation but at the cost of potentially increased rendering complexity or inexact reproduction. The goal of this report is to provide an overview that can guide practitioners and researchers in assessing the tradeoffs between current approaches and identifying directions for future advances in facial appearance capture.","lang":"eng"}],"title":"Recent advances in facial appearance capture","date_published":"2015-05-01T00:00:00Z","main_file_link":[{"url":"https://graphics.ethz.ch/~mpapas/publications/fac_star.pdf"}],"language":[{"iso":"eng"}],"publication_status":"published","publication":"Computer Graphics Forum","type":"journal_article","page":"709 - 733","date_created":"2018-12-11T11:53:43Z","_id":"1734","article_processing_charge":"No","intvolume":"        34","issue":"2","publisher":"Wiley-Blackwell","scopus_import":"1","status":"public","day":"01","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","external_id":{"isi":["000358326600063"]},"volume":34,"month":"05","department":[{"_id":"BeBi"}],"publist_id":"5391","citation":{"ista":"Klehm O, Rousselle F, Papas M, Bradley D, Hery C, Bickel B, Jarosz W, Beeler T. 2015.

Here, we consider the implications of a 3–8 times shorter orbital period, suggested by hydrodynamical simulations of circumbinary discs (CBDs) with nearly equal-mass SMBHBs (q ≡ M2/M1 ≳ 0.3). With the corresponding 2–4 times tighter binary separation, PG 1302 would be undergoing gravitational wave dominated inspiral, and serve as a proof that the BHs can be fuelled and produce bright emission even in this late stage of the merger. The expected fraction of binaries with the shorter tbin, among bright quasars, would be reduced by one to two orders of magnitude, compared to the 5.2 yr period, in better agreement with the rarity of candidates reported by Graham et al. Finally, shorter periods would imply higher binary speeds, possibly imprinting periodicity on the light curves from relativistic beaming, as well as measurable relativistic effects on the Fe K α line. The CBD model predicts additional periodic variability on time-scales of tbin and ≈0.5tbin, as well as periodic variation of broad line widths and offsets relative to the narrow lines, which are consistent with the observations. Future observations will be able to test these predictions and hence the binary+CBD hypothesis for PG 1302."}],"title":"A reduced orbital period for the supermassive black hole binary candidate in the quasar PG 1302-102?","date_published":"2015-07-24T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stv1457"}],"language":[{"iso":"eng"}],"oa":1,"extern":"1","publication_status":"published","publication":"Monthly Notices of the Royal Astronomical Society","type":"journal_article","page":"2540-2545","date_created":"2024-09-05T13:31:30Z","_id":"17615","article_processing_charge":"No","intvolume":"       452","issue":"3"},{"intvolume":"       454","issue":"1","type":"journal_article","page":"L21-L25","date_created":"2024-09-05T13:51:39Z","_id":"17622","article_processing_charge":"No","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnrasl/slv111"}],"language":[{"iso":"eng"}],"extern":"1","oa":1,"publication":"Monthly Notices of the Royal Astronomical Society: Letters","publication_status":"published","date_updated":"2024-09-24T08:34:12Z","publication_identifier":{"issn":["1745-3933","1745-3925"]},"doi":"10.1093/mnrasl/slv111","abstract":[{"text":"Graham et al. discovered a supermassive black hole binary (SMBHB) candidate and identified the detected 5.2 yr period of the optical variability as the orbital period of the binary. Hydrodynamical simulations predict multiple periodic components for the variability of SMBHBs, thus raising the possibility that the true period of the binary is different from 5.2 yr. We analyse the periodogram of PG1302 and find no compelling evidence for additional peaks. We also point out that, despite the 5.2 yr peak being significant if a single source is considered, further analysis is required to account for the fact that PG1302 was selected among a large sample of 247 000 quasars. We derive upper limits on any additional periodic modulations in the available data, by modelling the light curve as the sum of stochastic noise and the known 5.2 yr periodic component, and injecting additional sinusoidal signals. We find that, with the current data, we would be able to detect with high significance (false alarm probability <1 per cent) secondary periodic terms, with periods in the range predicted by the simulations, if the amplitude of the variability was at least ∼0.06 mag (compared to 0.14 mag for the main sinusoid). A three-year follow-up monitoring campaign with weekly observations can increase the sensitivity for detecting secondary peaks by ≈50 per cent, and would allow a more robust test of predictions from hydrodynamical simulations.","lang":"eng"}],"title":"Multiple periods in the variability of the supermassive black hole binary candidate quasar PG1302-102?","date_published":"2015-09-11T00:00:00Z","quality_controlled":"1","oa_version":"Published Version","year":"2015","author":[{"last_name":"Charisi","first_name":"M.","full_name":"Charisi, M."},{"first_name":"I.","last_name":"Bartos","full_name":"Bartos, I."},{"last_name":"Haiman","first_name":"Zoltán","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"full_name":"Price-Whelan, A.

We study atomic cooling haloes in the redshift range 100>z>9 with masses of order 109M⊙ at redshift z=10. We assume that the gas has primordial composition and that H2-cooling and prior star-formation in the haloes have been suppressed. We present a comprehensive analysis of the gas and dark matter properties of four halos with very low (λ≈0.01), low (λ≈0.04), high (λ≈0.06) and very high (λ≈0.1) spin parameter. Our main conclusion is that the spin orientation and magnitude is initially well described by tidal torque linear theory, but later on is determined by the merging and accretion history of each halo. We provide evidence that the topology of the merging region, i.e. the number of colliding filaments, gives an accurate prediction for the spin of dark matter and gas: halos at the center of knots will have low spin while those in the center of filaments will have high spin. The spin of a halo is given by λ≈0.05×(7.6/numberoffilaments)^5.1"}],"intvolume":"       452","issue":"1","date_created":"2024-09-06T07:18:53Z","page":"784-802","type":"journal_article","article_processing_charge":"No","_id":"17641"}]
