In this work, the mechanisms to achieve unprecedented size, shape, and composition control in quaternary nanocrystals are detailed.

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. acknowledgement: This work was supported by the Spanish MICINN Projects MAT2008-05779, MAT2008-03400-E/MAT, MAT2010-15138, ENE2008-03277-E/CON, CSD2009-00050. and CSD2009-00013.

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. author: - first_name: Arkadeb full_name: Ghosal, Arkadeb last_name: Ghosal - first_name: Daniel full_name: Iercan, Daniel last_name: Iercan - first_name: Christoph full_name: Kirsch, Christoph last_name: Kirsch - first_name: Thomas A full_name: Henzinger, Thomas A id: 40876CD8-F248-11E8-B48F-1D18A9856A87 last_name: Henzinger orcid: 0000−0002−2985−7724 - first_name: Alberto full_name: Sangiovanni Vincentelli, Alberto last_name: Sangiovanni Vincentelli citation: ama: Ghosal A, Iercan D, Kirsch C, Henzinger TA, Sangiovanni Vincentelli A.

The objective of the game combines a (qualitative) parity condition with the (quantitative) requirement that the sum of the weights (i.e., the level of energy in the game) must remain positive. Beside their own interest in the design and synthesis of resource-constrained omega-regular specifications, energy parity games provide one of the simplest model of games with combined qualitative and quantitative objectives. Our main results are as follows: (a) exponential memory is sufficient and may be necessary for winning strategies in energy parity games; (b) the problem of deciding the winner in energy parity games can be solved in NP ∩ coNP; and (c) we give an algorithm to solve energy parity by reduction to energy games. We also show that the problem of deciding the winner in energy parity games is logspace-equivalent to the problem of deciding the winner in mean-payoff parity games, which can thus be solved in NP ∩ coNP. As a consequence we also obtain a conceptually simple algorithm to solve mean-payoff parity games.' author: - first_name: Krishnendu full_name: Chatterjee, Krishnendu id: 2E5DCA20-F248-11E8-B48F-1D18A9856A87 last_name: Chatterjee orcid: 0000-0002-4561-241X - first_name: Laurent full_name: Doyen, Laurent last_name: Doyen citation: ama: Chatterjee K, Doyen L.

In this article, we consider algorithmic verification of programs that use Boolean variables, and in addition, access a single read-only array whose length is potentially unbounded, and whose elements range over an unbounded data domain. We show that the reachability problem, while undecidable in general, is (1) PSPACE-complete for programs in which the array-accessing for-loops are not nested, (2) decidable for a restricted class of programs with doubly nested loops. The second result establishes connections to automata and logics defining languages over data words. acknowledgement: This research was supported in part by the NSF Cybertrust award CNS 0524059, by the European Research Council (ERC) Advanced Investigator Grant QUAREM, and by the Austrian Science Fund (FWF) project S11402-N23. article_number: '27' author: - first_name: Rajeev full_name: Alur, Rajeev last_name: Alur - first_name: Pavol full_name: Cerny, Pavol id: 4DCBEFFE-F248-11E8-B48F-1D18A9856A87 last_name: Cerny - first_name: Scott full_name: Weinstein, Scott last_name: Weinstein citation: ama: Alur R, Cerny P, Weinstein S.

Identifying RSA-associated genes also represents an underexplored opportunity for crop improvement. Software tools are needed to accelerate the pace at which quantitative traits of RSA are estimated from images of root networks.Results: We have developed GiA Roots (General Image Analysis of Roots), a semi-automated software tool designed specifically for the high-throughput analysis of root system images. GiA Roots includes user-assisted algorithms to distinguish root from background and a fully automated pipeline that extracts dozens of root system phenotypes. Quantitative information on each phenotype, along with intermediate steps for full reproducibility, is returned to the end-user for downstream analysis. GiA Roots has a GUI front end and a command-line interface for interweaving the software into large-scale workflows. GiA Roots can also be extended to estimate novel phenotypes specified by the end-user.Conclusions: We demonstrate the use of GiA Roots on a set of 2393 images of rice roots representing 12 genotypes from the species Oryza sativa. We validate trait measurements against prior analyses of this image set that demonstrated that RSA traits are likely heritable and associated with genotypic differences. Moreover, we demonstrate that GiA Roots is extensible and an end-user can add functionality so that GiA Roots can estimate novel RSA traits. In summary, we show that the software can function as an efficient tool as part of a workflow to move from large numbers of root images to downstream analysis.' article_number: '116' article_processing_charge: No author: - first_name: Taras full_name: Galkovskyi, Taras last_name: Galkovskyi - first_name: Yuriy full_name: Mileyko, Yuriy last_name: Mileyko - first_name: Alexander full_name: Bucksch, Alexander last_name: Bucksch - first_name: Brad full_name: Moore, Brad last_name: Moore - first_name: Olga full_name: Symonova, Olga id: 3C0C7BC6-F248-11E8-B48F-1D18A9856A87 last_name: Symonova - first_name: Charles full_name: Price, Charles last_name: Price - first_name: Chrostopher full_name: Topp, Chrostopher last_name: Topp - first_name: Anjali full_name: Iyer Pascuzzi, Anjali last_name: Iyer Pascuzzi - first_name: Paul full_name: Zurek, Paul last_name: Zurek - first_name: Suqin full_name: Fang, Suqin last_name: Fang - first_name: John full_name: Harer, John last_name: Harer - first_name: Philip full_name: Benfey, Philip last_name: Benfey - first_name: Joshua full_name: Weitz, Joshua last_name: Weitz citation: ama: 'Galkovskyi T, Mileyko Y, Bucksch A, et al.
