Their functional roles are assumed to be defined by the identity of their input synapses, the architecture of their dendritic tree, the passive and active membrane properties and finally the nature of their postsynaptic targets. Indeed, interneurons display a high degree of morphological and physiological heterogeneity. However, whether their morphological and physiological characteristics are correlated and whether interneuron diversity can be described by a continuum of GABAergic cell types or by distinct classes has remained unclear. Here we perform a detailed morphological and physiological characterization of GABAergic cells in the dentate gyrus, the input region of the hippocampus. To achieve an unbiased and efficient sampling and classification we used knock-in mice expressing the enhanced green fluorescent protein (eGFP) in glutamate decarboxylase 67 (GAD67)-positive neurons and performed cluster analysis. We identified five interneuron classes, each of them characterized by a distinct set of anatomical and physiological parameters. Cross-correlation analysis further revealed a direct relation between morphological and physiological properties indicating that dentate gyrus interneurons fall into functionally distinct classes which may differentially control neuronal network activity.","lang":"eng"}],"month":"02","type":"journal_article","oa_version":"Published Version","_id":"2285","acknowledgement":"Funded by Deutsche Forschungsgemeinschaft.

Our starting point is the experimental observation that RM codes have a smaller error probability than polar codes under MAP decoding. This motivates us to introduce a family of codes that “interpolates” between RM and polar codes, call this family C inter = {C α : α ∈ [0, 1j}, where C α|α=1 is the original polar code, and C α|α=0 is an RM code. Based on numerical observations, we remark that the error probability under MAP decoding is an increasing function of α. MAP decoding has in general exponential complexity, but empirically the performance of polar codes at finite block lengths is boosted by moving along the family Cinter even under low-complexity decoding schemes such as, for instance, belief propagation or successive cancellation list decoder. We demonstrate the performance gain via numerical simulations for transmission over the erasure channel as well as the Gaussian channel."}]},{"external_id":{"arxiv":["1406.7373"]},"status":"public","extern":"1","related_material":{"record":[{"relation":"later_version","status":"public","id":"6678"}]},"conference":{"end_date":"2014-10-03","start_date":"2014-09-30","location":"Monticello, IL, United States","name":"Allerton Conference on Communication, Control, and Computing"},"language":[{"iso":"eng"}],"citation":{"chicago":"Mondelli, Marco, Rudiger Urbanke, and Hamed Hassani. “How to Achieve the Capacity of Asymmetric Channels.” In 52nd Annual Allerton Conference on Communication, Control, and Computing, 789–96.

To do so, we discuss how recent advances in coding for symmetric channels yield more efficient solutions also for the asymmetric case. In more detail, we consider three basic approaches. The first one is Gallager's scheme that concatenates a linear code with a non-linear mapper, in order to bias the input distribution. We explicitly show that both polar codes and spatially coupled codes can be employed in this scenario. Further, we derive a scaling law between the gap to capacity, the cardinality of channel input and output alphabets, and the required size of the mapper. The second one is an integrated approach in which the coding scheme is used both for source coding, in order to create codewords with the capacity-achieving distribution, and for channel coding, in order to provide error protection. Such a technique has been recently introduced by Honda and Yamamoto in the context of polar codes, and we show how to apply it also to the design of sparse graph codes. The third approach is based on an idea due to Böcherer and Mathar and separates completely the two tasks of source coding and channel coding by “chaining” together several codewords. We prove that we can combine any suitable source code with any suitable channel code in order to provide optimal schemes for asymmetric channels. In particular, polar codes and spatially coupled codes fulfill the required conditions."}],"month":"10","oa_version":"Preprint","type":"conference","arxiv":1,"title":"How to achieve the capacity of asymmetric channels","date_created":"2019-07-31T07:24:23Z"},{"year":"2014","publisher":"IEEE","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"6744","publication":"IEEE Transactions on Wireless Communications","month":"03","type":"journal_article","oa_version":"None","abstract":[{"lang":"eng","text":"With the aim of extending the coverage and improving the performance of impulse radio ultra-wideband (UWB) systems, this paper focuses on developing a novel single differential encoded decode and forward (DF) non-cooperative relaying scheme (NCR). To favor simple receiver structures, differential noncoherent detection is employed which enables effective energy capture without any channel estimation. Putting emphasis on the general case of multi-hop relaying, we illustrate an original algorithm for the joint power allocation and path selection (JPAPS), minimizing an approximate expression of the overall bit error rate (BER). In particular, after deriving a closed-form power allocation strategy, the optimal path selection is reduced to a shortest path problem on a connected graph, which can be solved without any topology information with complexity O(N 3 ), N being the number of available relays of the network. An approximate scheme is also presented, which reduces the complexity to O(N 2 ) while showing a negligible performance loss, and for benchmarking purposes, an exhaustive-search based multi-hop DF cooperative strategy is derived. Simulation results for various network setups corroborate the effectiveness of the proposed low-complexity JPAPS algorithm, which favorably compares to existing AF and DF relaying methods."}],"date_updated":"2021-01-12T08:08:48Z","day":"20","author":[{"full_name":"Mondelli, Marco","id":"27EB676C-8706-11E9-9510-7717E6697425","orcid":"0000-0002-3242-7020","last_name":"Mondelli","first_name":"Marco"},{"full_name":"Zhou, Qi","last_name":"Zhou","first_name":"Qi"},{"last_name":"Lottici","first_name":"Vincenzo","full_name":"Lottici, Vincenzo"},{"first_name":"Xiaoli","last_name":"Ma","full_name":"Ma, Xiaoli"}],"page":"1397-1409","date_created":"2019-07-31T09:05:07Z","title":"Joint power allocation and path selection for multi-hop noncoherent decode and forward UWB communications","volume":13,"status":"public","issue":"3","language":[{"iso":"eng"}],"citation":{"ieee":"M.

Iridium-based oxides (iridates) introduce strong spin–orbit coupling directly, such that these numbers become entwined together and the Mott physics attains a strong orbital character. In the layered honeycomb iridates this is thought to generate highly spin–anisotropic magnetic interactions, coupling the spin to a given spatial direction of exchange and leading to strongly frustrated magnetism. Here we report a new iridate structure that has the same local connectivity as the layered honeycomb and exhibits striking evidence for highly spin–anisotropic exchange. The basic structural units of this material suggest that a new family of three-dimensional structures could exist, the ‘harmonic honeycomb’ iridates, of which the present compound is the first example."}],"_id":"7071","year":"2014"},{"_id":"7072","publication":"Physical Review Letters","article_type":"original","article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"APS","year":"2014","article_number":"207201","volume":112,"title":"Controlling magnetic order and quantum disorder in molecule-based magnets","date_created":"2019-11-19T13:23:13Z","author":[{"full_name":"Lancaster, T.","last_name":"Lancaster","first_name":"T."},{"full_name":"Goddard, P.

That is demonstrated by fluorescence measurements involving several classes of fluorophores. Electrochemical measurements show that PET in several amino-modified dyes is thermodynamically favorable, even though it was not experimentally found, underlining the importance of kinetic aspects to the process. Consequently, the attachment of phenolic groups allows for fast and simple preparation of a wide selection of fluorescent pH-probes with tailor-made spectral properties, sensitive ranges, and individual advantages, so that a large number of applications can be realized.

In the absence of Li+, the complexing-cations also promote the reduction of O2•– to O22–.

Here, we studied ionic transport properties and Li self-diffusion in nanocrystalline Li2O2 by conductivity and temperature variable 7Li NMR spectroscopy. Nanostructured Li2O2, characterized by a mean crystallite size of less than 50 nm as estimated from X-ray diffraction peak broadening, was prepared by high-energy ball milling of microcrystalline lithium peroxide with μm sized crystallites. At room temperature the overall conductivity σ of the microcrystalline reference sample turned out to be very low (3.4 × 10−13 S cm−1) which is in agreement with results from temperature-variable 7Li NMR line shape measurements. Ball-milling, however, leads to an increase of σ by approximately two orders of magnitude (1.1 × 10−10 S cm−1); correspondingly, the activation energy decreases from 0.89 eV to 0.82 eV. The electronic contribution σeon, however, is in the order of 9 × 10−12 S cm−1 which makes less than 10% of the total value. Interestingly, 7Li NMR lines of nano-Li2O2 undergo pronounced heterogeneous motional narrowing which manifests in a two-component line shape emerging with increasing temperatures. Most likely, the enhancement in σ can be traced back to the generation of a spin reservoir with highly mobile Li ions; these are expected to reside in the nearest neighbourhood of defects generated or near the structurally disordered and defect-rich interfacial regions formed during mechanical treatment.","lang":"eng"}],"date_updated":"2021-01-12T08:12:53Z","oa_version":"Published Version","month":"08","type":"journal_article","extern":"1","intvolume":" 7","citation":{"ieee":"A.

It must possess a wide range of attributes, exceeding the requirements of electrolytes for Lithium ion batteries by far. The most important additional issues are stability at both anode and cathode in the presence of O2. The known problems with cycling the Li metal/non-aqueous electrolyte interface are further complicated by O2. New and much less understood are the reactions at the O2 cathode/electrolyte interface where the highly reversible formation/decomposition of Li2O2 on discharge/charge is critical for the operation of the non-aqueous lithium air battery. Many aprotic electrolytes exhibit decomposition at the cathode during discharge and charge due to the presence of reactive reduced O2 species affecting potential, capacity and kinetics on discharge and charge, cyclability and calendar life. Identifying suitable electrolytes is one of the key challenges for the non-aqueous lithium air battery at the present time. Following the realisation that cyclability of such cells in the initially used organic carbonate electrolytes is due to back-to-back irreversible reactions the stability of the non-aqueous electrolytes became a major focus of research on rechargeable lithium air batteries. This realisation led to the establishment of a suite of experimental and computational methods capable of screening the stability of electrolytes. These allow for greater mechanistic understanding of the reactivity and guide the way towards designing more stable systems. A range of electrolytes based on ethers, amides, sulfones, ionic liquids and dimethyl sulfoxide have been investigated. All are more stable than the organic carbonates, but not all are equally stable. Even though it was soon realised, by a number of groups, that ethers exhibit side reactions on discharge and charge, they still remain the choice in many studies. To date dimethyl sulfoxide and dimethylacetamide were identified as the most stable electrolytes. In conjunction with the investigation of electrolyte stability the importance of electrode stability became more prominent. The stability of the electrolyte cannot be considered in isolation. Its stability depends on the synergy between electrolyte and electrode. Carbon based electrodes promote electrolyte decomposition and decompose on their own. Although great progress has been made in only a few years, future work on aprotic electrolytes for Li-O2 batteries will need to explore other electrolytes in the quest for yet lower cost, higher safety, stability and low volatility.","lang":"eng"}],"date_updated":"2021-01-12T08:12:54Z","day":"05","oa_version":"None","type":"book_chapter","month":"03","title":"Nonaqueous Electrolytes","date_created":"2020-01-15T12:17:55Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Springer Nature","place":"New York, NY","year":"2014","publication":"The Lithium Air Battery: Fundamentals","_id":"7303","article_processing_charge":"No"},{"abstract":[{"lang":"eng","text":"Lithium-air batteries have received extraordinary attention recently owing to their theoretical gravimetric energies being considerably higher than those of Li-ion batteries.

In this article, we discuss recent advances in the mechanistic understanding of oxygen redox reactions in nonaqueous electrolytes and the search for electrolytes and electrode materials that are chemically stable in the oxygen electrode. In addition, methods to protect lithium metal against corrosion by water and dendrite formation in aqueous lithium-air batteries are discussed.

Understanding the fundamental mechanism of O2 reduction in aprotic solvents is therefore essential to realizing their technological potential. Two different models have been proposed for Li2O2 formation, involving either solution or electrode surface routes. Here, we describe a single unified mechanism, which, unlike previous models, can explain O2 reduction across the whole range of solvents and for which the two previous models are limiting cases. We observe that the solvent influences O2 reduction through its effect on the solubility of LiO2, or, more precisely, the free energy of the reaction LiO2* ⇌ Li(sol)+ + O2−(sol) + ion pairs + higher aggregates (clusters). The unified mechanism shows that low-donor-number solvents are likely to lead to premature cell death, and that the future direction of research for lithium–oxygen batteries should focus on the search for new, stable, high-donor-number electrolytes, because they can support higher capacities and can better sustain discharge.","lang":"eng"}],"page":"1091-1099","author":[{"full_name":"Johnson, Lee","last_name":"Johnson","first_name":"Lee"},{"first_name":"Chunmei","last_name":"Li","full_name":"Li, Chunmei"},{"first_name":"Zheng","last_name":"Liu","full_name":"Liu, Zheng"},{"last_name":"Chen","first_name":"Yuhui","full_name":"Chen, Yuhui"},{"last_name":"Freunberger","first_name":"Stefan Alexander","full_name":"Freunberger, Stefan Alexander","orcid":"0000-0003-2902-5319","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425"},{"first_name":"Praveen C.","last_name":"Ashok","full_name":"Ashok, Praveen C."},{"full_name":"Praveen, Bavishna B.","first_name":"Bavishna B.","last_name":"Praveen"},{"first_name":"Kishan","last_name":"Dholakia","full_name":"Dholakia, Kishan"},{"full_name":"Tarascon, Jean-Marie","first_name":"Jean-Marie","last_name":"Tarascon"},{"first_name":"Peter G.","last_name":"Bruce","full_name":"Bruce, Peter G."}],"issue":"12","citation":{"ama":"Johnson L, Li C, Liu Z, et al.

However, a mutual repressor-based toggle switch comprising DNA-binding domains of transcription-activator-like effectors (TALEs) did not support bistability in mammalian cells. Here, the challenge of engineering a bistable switch based on monomeric DNA-binding domains is solved via the introduction of a positive feedback loop composed of activators based on the same TALE domains as their opposing repressors and competition for the same DNA operator site. This design introduces nonlinearity and results in epigenetic bistability.

This paper considers a new dynamic version of the problem, in which tasks are injected adversarially during an asynchronous execution. We give the first asynchronous shared-memory algorithm for dynamic task allocation, and we prove that our solution is optimal within logarithmic factors. The main algorithmic idea is a randomized concurrent data structure called a dynamic to-do tree, which allows processes to pick new tasks to perform at random from the set of available tasks, and to insert tasks at random empty locations in the data structure. Our analysis shows that these properties avoid duplicating work unnecessarily. On the other hand, since the adversary controls the input as well the scheduling, it can induce executions where lots of processes contend for a few available tasks, which is inefficient. However, we prove that every algorithm has the same problem: given an arbitrary input, if OPT is the worst-case complexity of the optimal algorithm on that input, then the expected work complexity of our algorithm on the same input is O(OPT log3 m), where m is an upper bound on the number of tasks that are present in the system at any given time."}],"date_updated":"2023-02-23T13:13:52Z","type":"conference","oa_version":"None","month":"01","author":[{"full_name":"Alistarh, Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3650-940X","first_name":"Dan-Adrian","last_name":"Alistarh"},{"full_name":"Aspnes, James","last_name":"Aspnes","first_name":"James"},{"full_name":"Bender, Michael","last_name":"Bender","first_name":"Michael"},{"full_name":"Gelashvili, Rati","last_name":"Gelashvili","first_name":"Rati"},{"first_name":"Seth","last_name":"Gilbert","full_name":"Gilbert, Seth"}],"page":"416 - 435","publist_id":"6886","date_created":"2018-12-11T11:48:24Z","title":"Dynamic task allocation in asynchronous shared memory","year":"2014","publisher":"SIAM","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"Dan Alistarh - This author was supported by the SNF Postdoctoral Fellows Program, NSF grant CCF-1217921, DoE ASCR grant ER26116/DE-SC0008923, and by grants from the Oracle and Intel corporations.\r\nJames Aspnes - Supported in part by NSF grant CCF-0916389.\r\nMichael A.

We first prove an individual lower bound of ω(k) process steps for deterministic renaming into any namespace of size subexponential in k, where k is the number of participants. The bound is tight: it draws an exponential separation between deterministic and randomized solutions, and implies new tight bounds for deterministic concurrent fetch-and-increment counters, queues, and stacks. The proof is based on a new reduction from renaming to another fundamental problem in distributed computing: mutual exclusion. We complement this individual bound with a global lower bound of ω(klog(k/c)) on the total step complexity of renaming into a namespace of size ck, for any c = 1. This result applies to randomized algorithms against a strong adversary, and helps derive new global lower bounds for randomized approximate counter implementations, that are tight within logarithmic factors. On the algorithmic side, we give a protocol that transforms any sorting network into a randomized strong adaptive renaming algorithm, with expected cost equal to the depth of the sorting network. This gives a tight adaptive renaming algorithm with expected step complexity O(log k), where k is the contention in the current execution. This algorithm is the first to achieve sublinear time, and it is time-optimal as per our randomized lower bound. Finally, we use this renaming protocol to build monotone-consistent counters with logarithmic step complexity and linearizable fetch-and-increment registers with polylogarithmic cost."}],"date_updated":"2023-02-23T13:14:09Z","day":"01","month":"05","type":"journal_article","oa_version":"None","author":[{"first_name":"Dan-Adrian","last_name":"Alistarh","orcid":"0000-0003-3650-940X","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","full_name":"Alistarh, Dan-Adrian"},{"full_name":"Aspnes, James","first_name":"James","last_name":"Aspnes"},{"first_name":"Keren","last_name":"Censor Hillel","full_name":"Censor Hillel, Keren"},{"full_name":"Gilbert, Seth","first_name":"Seth","last_name":"Gilbert"},{"first_name":"Rachid","last_name":"Guerraoui","full_name":"Guerraoui, Rachid"}],"article_processing_charge":"No","publication":"Journal of the ACM","_id":"769","year":"2014","publisher":"ACM","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"The work of J.
