High-resolution transmission electron microscopy and X-ray diffraction analysis showed the nanocrystals to have a crystallographic structure compatible with that of the kesterite. Chemical characterization of the materials showed the presence of the four elements in each individual nanocrystal.

For both discounted and mean-payoff two-level games, we show the existence of pure memoryless optimal strategies for both players and an ordered field property. We show that if there is only one player (Markov decision processes), then the values can be computed in polynomial time. It follows that whether the value of a player is equal to a given rational constant in two-level discounted or mean-payoff games can be decided in NP ∩ coNP.

Molecular analysis suggests that this tight coupling is generated by protein–protein interactions involving Ca2+ channels, Ca2+ sensors and various other synaptic proteins.

The games are concurrent: in each round, the two players (player 1 and player 2) choose their moves independently and simultaneously; the current state and the two moves determine a probability distribution over the successor states. We also consider the important special case of turn-based stochastic games where players make moves in turns, rather than concurrently. We study concurrent games with \\omega-regular winning conditions specified as parity objectives. The value for player 1 for a parity objective is the maximal probability with which the player can guarantee the satisfaction of the objective against all strategies of the opponent. We study the problem of continuity and robustness of the value function in concurrent and turn-based stochastic parity gameswith respect to imprecision in the transition probabilities. We present quantitative bounds on the difference of the value function (in terms of the imprecision of the transition probabilities) and show the value continuity for structurally equivalent concurrent games (two games are structurally equivalent if the support of the transition function is same and the probabilities differ). We also show robustness of optimal strategies for structurally equivalent turn-based stochastic parity games. Finally we show that the value continuity property breaks without the structurally equivalent assumption (even for Markov chains) and show that our quantitative bound is asymptotically optimal. Hence our results are tight (the assumption is both necessary and sufficient) and optimal (our quantitative bound is asymptotically optimal)."}],"arxiv":1,"page":"270 - 285","day":"22","doi":"10.1007/978-3-642-28729-9_18","scopus_import":1,"oa":1},{"_id":"338","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"last_name":"Ibáñez","id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria","full_name":"Ibáñez, Maria","orcid":"0000-0001-5013-2843"},{"last_name":"Zamani","full_name":"Zamani, Reza","first_name":"Reza"},{"last_name":"Li","first_name":"Wenhua","full_name":"Li, Wenhua"},{"last_name":"Shavel","first_name":"Alexey","full_name":"Shavel, Alexey"},{"last_name":"Arbiol","first_name":"Jordi","full_name":"Arbiol, Jordi"},{"last_name":"Morante","first_name":"Joan","full_name":"Morante, Joan"},{"last_name":"Cabot","first_name":"Andreu","full_name":"Cabot, Andreu"}],"intvolume":"        12","citation":{"ista":"Ibáñez M, Zamani R, Li W, Shavel A, Arbiol J, Morante J, Cabot A. 2012.

It is also shown here how the diversity of valences in the constituent elements allows an effective control of their electrical conductivity through the adjustment of the cation ratios. At the same time, while the crystallographic complexity of quaternary chalcogenides is associated with intrinsically low thermal conductivities, the reduction of the lattice dimensions to the nanoscale further reduces the materials thermal conductivity. In the specific case of the stannite crystal structure, a convenient slab distribution of the valence band maximum states permits a partial decoupling of the p-type electrical conductivity from both the Seebeck coefficient and the thermal conductivity. Combining these features, we demonstrate how an initial optimization of the nanocrystals Cd/Cu ratio allowed us to obtain low-temperature solution-processed materials with ZT values up to 0.71 at 685 K.","lang":"eng"}],"publist_id":"7489","article_processing_charge":"No","author":[{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","last_name":"Ibáñez","orcid":"0000-0001-5013-2843","first_name":"Maria","full_name":"Ibáñez, Maria"},{"first_name":"Doris","full_name":"Cadavid, Doris","last_name":"Cadavid"},{"first_name":"Reza","full_name":"Zamani, Reza","last_name":"Zamani"},{"full_name":"García Castelló, Nuria","first_name":"Nuria","last_name":"García Castelló"},{"last_name":"Izquierdo Roca","first_name":"Victora","full_name":"Izquierdo Roca, Victora"},{"last_name":"Li","first_name":"Wenhua","full_name":"Li, Wenhua"},{"full_name":"Fairbrother, Andrew","first_name":"Andrew","last_name":"Fairbrother"},{"first_name":"Joan","full_name":"Prades, Joan","last_name":"Prades"},{"first_name":"Alexey","full_name":"Shavel, Alexey","last_name":"Shavel"},{"first_name":"Jordi","full_name":"Arbiol, Jordi","last_name":"Arbiol"},{"full_name":"Pérez Rodríguez, Alejandro","first_name":"Alejandro","last_name":"Pérez Rodríguez"},{"full_name":"Morante, Joan","first_name":"Joan","last_name":"Morante"},{"last_name":"Cabot","first_name":"Andreu","full_name":"Cabot, Andreu"}],"intvolume":"        24","_id":"339","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"year":"2012","article_type":"original","type":"journal_article","citation":{"apa":"Ibáñez, M., Cadavid, D., Zamani, R., García Castelló, N., Izquierdo Roca, V., Li, W., … Cabot, A.

First, single-crystal ZnO NWs with controlled n-type doping were grown on conducting substrates by a low-cost, high-yield and seed-free electrochemical route. These NWs were covered by a titanium oxide shell of tunable thickness mediating successive adsorption-hydrolysis-condensation steps. Using this atomic-layer growth procedure, titania shells with controlled thickness and the anatase TiO2 phase were obtained after sintering at 450 °C. Higher sintering temperatures resulted in the formation of ZnO : Cl/ZnxTiOy/TiO2 core–shell NWs by the interdiffusion of Zn and Ti ions at the ZnO–TiO2 interface. The performance of ZnO : Cl/TiO2 and ZnO : Cl/ZnxTiOy/TiO2 core–shell NWs towards photoelectrochemical (PEC) water splitting was investigated as a function of the titania shell thickness. Furthermore, the performance of such core–shell NWs as photoelectrodes in dye-sensitized solar cells was also characterized. The TiO2 presence at the ZnO : Cl surface promoted a two-fold increase on the produced photocurrent densities, probing their potential for PEC and optoelectronic applications.

In the present work, we detail a novel colloidal synthesis route to prepare nanoparticles of the ternary semiconductor Cu2GeSe3 (CGSe) with nanometer-scale control over their crystal phases. We also demonstrate the structural effect on the thermoelectric properties of bottom-up-prepared CGSe nanomaterials. By careful adjustment of the nucleation and growth temperatures, pure orthorhombic CGSe nanoparticles with cationic order or polytypic CGSe nanoparticles with disordered cation positions can be produced. In this second type of nanoparticle, a high density of twins can be created to periodically change the atomic plane stacking, forming a hexagonal wurtzite CGSe phase. The high yield of the synthetic routes reported here allows the production of single-phase and multiphase CGSe nanoparticles in the gram scale, which permits characterization of the thermoelectric properties of these materials. Reduced thermal conductivities and a related 2.5-fold increase of the thermoelectric figure of merit for multiphase nanomaterials compared to pure-phase CGSe are systematically obtained. These results are discussed in terms of the density and efficiency of phonon scattering centers in both types of materials."}],"article_processing_charge":"No","publisher":"American Chemical Society","title":"Crystallographic control at the nanoscale to enhance functionality: Polytypic Cu2GeSe3 nanoparticles as thermoelectric materials","issue":"23","date_created":"2018-12-11T11:46:07Z","volume":24,"month":"11","status":"public","extern":"1","publication":"Chemistry of Materials"},{"publication_status":"published","external_id":{"isi":["000298464800003"]},"date_updated":"2025-09-30T07:33:11Z","oa_version":"None","date_published":"2012-02-01T00:00:00Z","department":[{"_id":"ToHe"}],"article_processing_charge":"No","publist_id":"2370","title":"Separate compilation of hierarchical real-time programs into linear-bounded embedded machine code","publisher":"Elsevier","volume":77,"month":"02","quality_controlled":"1","status":"public","language":[{"iso":"eng"}],"intvolume":"        77","author":[{"first_name":"Arkadeb","full_name":"Ghosal, Arkadeb","last_name":"Ghosal"},{"full_name":"Iercan, Daniel","first_name":"Daniel","last_name":"Iercan"},{"full_name":"Kirsch, Christoph","first_name":"Christoph","last_name":"Kirsch"},{"last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A","first_name":"Thomas A","orcid":"0000−0002−2985−7724"},{"last_name":"Sangiovanni Vincentelli","full_name":"Sangiovanni Vincentelli, Alberto","first_name":"Alberto"}],"_id":"3836","doi":"10.1016/j.scico.2010.06.004","scopus_import":"1","page":"96 - 112","day":"01","isi":1,"abstract":[{"lang":"eng","text":"Hierarchical Timing Language (HTL) is a coordination language for distributed, hard real-time applications. HTL is a hierarchical extension of Giotto and, like its predecessor, based on the logical execution time (LET) paradigm of real-time programming. Giotto is compiled into code for a virtual machine, called the EmbeddedMachine (or E machine). If HTL is targeted to the E machine, then the hierarchicalprogram structure needs to be flattened; the flattening makes separatecompilation difficult, and may result in E machinecode of exponential size. In this paper, we propose a generalization of the E machine, which supports a hierarchicalprogram structure at runtime through real-time trigger mechanisms that are arranged in a tree. We present the generalized E machine, and a modular compiler for HTL that generates code of linear size. The compiler may generate code for any part of a given HTL program separately in any order."}],"issue":"2","date_created":"2018-12-11T12:05:26Z","publication":"Science of Computer Programming","year":"2012","type":"journal_article","citation":{"apa":"Ghosal, A., Iercan, D., Kirsch, C., Henzinger, T.

Recent studies use biophysical models, genetics, and quantitative imaging to unravel how tissue-level morphogen behavior arises from subcellular events. Moreover, data from several systems show that morphogen gradients, downstream signaling, and the activity of cell-intrinsic transcriptional networks change dynamically during pattern formation. Studies from Drosophila and now also vertebrates suggest that transcriptional network dynamics are central to the generation of gene expression patterns. Together, this leads to the view that pattern formation is an emergent behavior that results from the coordination of events occurring across molecular, cellular, and tissue scales. The development of novel approaches to study this complex process remains a challenge.","lang":"eng"}],"publist_id":"5404","publisher":"American Association for the Advancement of Science","title":"Developmental pattern formation: Insights from physics and biology","intvolume":"       338","author":[{"orcid":"0000-0003-4509-4998","first_name":"Anna","full_name":"Anna Kicheva","id":"3959A2A0-F248-11E8-B48F-1D18A9856A87","last_name":"Kicheva"},{"full_name":"Cohen, Michael H","first_name":"Michael","last_name":"Cohen"},{"last_name":"Briscoe","first_name":"James","full_name":"Briscoe, James"}],"_id":"1725","year":"2012","type":"journal_article","citation":{"chicago":"Kicheva, Anna, Michael Cohen, and James Briscoe. “Developmental Pattern Formation: Insights from Physics and Biology.” <i>Science</i>.

By independently tuning the effective Schottky barrier heights, a variety of reconfigurable device functionalities could be obtained. In particular, the same nanowire device could be configured to work as a Schottky barrier transistor, a Schottky diode, or a p-n diode with tunable polarities.

By varying the superconducting gap Δ with a magnetic field B we investigated the transition from strong coupling Δ≪T K to weak-coupling Δ≫T K, where T K is the Kondo temperature. Below the critical field, we observe a persisting zero-bias Kondo resonance that vanishes only for low B or higher temperatures, leaving the room to more robust subgap structures at bias voltages between Δ and 2Δ. For strong and approximately symmetric tunnel couplings, a Josephson supercurrent is observed in addition to the Kondo peak. We ascribe the coexistence of a Kondo resonance and a superconducting gap to a significant density of intragap quasiparticle states, and the finite-bias subgap structures to tunneling through Shiba states.

We examine steady-state configurations of the disk and migrating SMBH system, self-consistently accounting for tidal and viscous torques and heating, radiative diffusion limited cooling, gas and radiation pressure, and the decay of the binary's orbit. We obtain a \"phase diagram\" of the system as a function of binary parameters, showing regimes in which both the disk structure and migration have a different character. Although massive binaries can create a central gap in the disk at large radii, the tidal barrier of the secondary causes a significant pile-up of gas outside of its orbit, which can lead to the closing of the gap. We find that this spillover occurs at an orbital separation as large as ~200 M_7^{-1/2} gravitational radii, where M = 10^7 M_7 Msun is the total binary mass. If the secondary is less massive than ~10^6 Msun, then the gap is closed before gravitational waves (GWs) start dominating the orbital decay. In this regime, the disk is still strongly perturbed, but the piled-up gas continuously overflows as in a porous dam, and crosses inside the secondary's orbit. The corresponding migration rate, which we label Type 1.5, is slower than the usual limiting cases known as Type I and II migration. Compared to an unperturbed disk, the steady-state disk in the overflowing regime is up to several hundred times brighter in the optical bands. Surveys such as PanSTARRS or LSST may discover the periodic variability of this population of binaries. Our results imply that the circumbinary disks around SMBHs can extend to small radii during the last stages of their merger, when they are detectable by LISA, and may produce coincident electromagnetic (EM) emission similar to active galactic nuclei (AGN)."}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","alternative_title":["Overflow and migration: SMBH binaries"],"year":"2012","type":"journal_article","citation":{"ista":"Kocsis B, Haiman Z, Loeb A. 2012.

Recent studies have suggested that a significant fraction of the first stars may have had low masses (a few M⊙). Such stars do not leave BH remnants and they have softer spectra, with copious infrared (IR) radiation at photon energies ∼1 eV. Similar to LW and X-ray photons, these photons have a mean-free path comparable to the Hubble distance, building up an early IR background. Here we show that if soft-spectrum stars, with masses of a few M⊙, contributed ≳0.3 per cent of the UV background (or their mass fraction exceeded ∼80 per cent), then their IR radiation dominated radiative feedback in the early Universe. The feedback is different from the UV feedback from high-mass stars, and occurs through the photodetachment of H− ions, necessary for efficient H2 formation. Nevertheless, we find that the baryon fraction which must be incorporated into low-mass stars in order to suppress H2 cooling is only a factor of a few higher than for high-mass stars.","lang":"eng"}],"page":"L51-L55","day":"01","doi":"10.1111/j.1745-3933.2012.01298.x","scopus_import":"1","oa":1,"extern":"1","publication":"Monthly Notices of the Royal Astronomical Society: Letters","date_created":"2024-09-06T07:07:07Z","issue":"1"}]
