Sn has been replaced with various lower group dopants to achieve successful p-type doping in SnSe with high ZT values. A known, facile, and powerful alternative way to introduce a hole carrier is to use a natural single Sn vacancy, VSn. Through transport and scanning tunneling microscopy studies, we discovered that VSn are dominant in high-quality (slow cooling rate) SnSe single crystals, while multiple vacancies, Vmulti, are dominant in low-quality (high cooling rate) single crystals. Surprisingly, both VSn and Vmulti help to increase the power factors of SnSe, whereas samples with dominant VSn have superior thermoelectric properties in SnSe single crystals. Additionally, the observation that Vmulti are good p-type sources observed in relatively low-quality single crystals is useful in thermoelectric applications because polycrystalline SnSe can be used due to its mechanical strength; this substance is usually fabricated at very high cooling speeds."}],"year":"2022","external_id":{"isi":["000794880200001"]},"volume":14,"quality_controlled":"1","article_type":"original","article_processing_charge":"No","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"MaIb"}],"has_accepted_license":"1","date_created":"2022-05-22T22:01:40Z","publication":"NPG Asia Materials","publisher":"Springer Nature","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","title":"Unidentified major p-type source in SnSe: Multivacancies","author":[{"full_name":"Nguyen, Van Quang","first_name":"Van Quang","last_name":"Nguyen"},{"first_name":"Thi Ly","last_name":"Trinh","full_name":"Trinh, Thi Ly"},{"full_name":"Chang, Cheng","first_name":"Cheng","orcid":"0000-0002-9515-4277","id":"9E331C2E-9F27-11E9-AE48-5033E6697425","last_name":"Chang"},{"first_name":"Li Dong","last_name":"Zhao","full_name":"Zhao, Li Dong"},{"full_name":"Nguyen, Thi Huong","last_name":"Nguyen","first_name":"Thi Huong"},{"first_name":"Van Thiet","last_name":"Duong","full_name":"Duong, Van Thiet"},{"full_name":"Duong, Anh Tuan","first_name":"Anh Tuan","last_name":"Duong"},{"full_name":"Park, Jong Ho","last_name":"Park","first_name":"Jong Ho"},{"last_name":"Park","first_name":"Sudong","full_name":"Park, Sudong"},{"full_name":"Kim, Jungdae","first_name":"Jungdae","last_name":"Kim"},{"full_name":"Cho, Sunglae","first_name":"Sunglae","last_name":"Cho"}],"isi":1,"file":[{"creator":"dernst","checksum":"0579997cc1d28bf66e29357e08e3e39d","file_id":"11404","access_level":"open_access","file_name":"2022_NPGAsiaMaterials_Nguyen.pdf","date_updated":"2022-05-23T06:47:57Z","date_created":"2022-05-23T06:47:57Z","content_type":"application/pdf","relation":"main_file","file_size":6202545,"success":1}],"acknowledgement":"This work was supported by the National Research Foundation of Korea [NRF-2019R1F1A1058473, NRF-2019R1A6A1A11053838, and NRF-2020K1A4A7A02095438].","day":"13","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"}},{"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publisher":"Elsevier","title":"Graph planning with expected finite horizon","acknowledgement":"This work was partially supported by Austrian Science Fund (FWF) NFN Grant No RiSE/SHiNE S11407 and by the grant ERC CoG 863818 (ForM-SMArt).","day":"01","author":[{"full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","last_name":"Chatterjee","orcid":"0000-0002-4561-241X","first_name":"Krishnendu"},{"full_name":"Doyen, Laurent","first_name":"Laurent","last_name":"Doyen"}],"isi":1,"project":[{"grant_number":"S11407","_id":"25863FF4-B435-11E9-9278-68D0E5697425","name":"Game Theory","call_identifier":"FWF"},{"grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications","call_identifier":"H2020"}],"article_type":"original","article_processing_charge":"No","volume":129,"quality_controlled":"1","external_id":{"isi":["000805002800001"],"arxiv":["1802.03642"]},"related_material":{"record":[{"id":"7402","relation":"earlier_version","status":"public"}]},"publication":"Journal of Computer and System Sciences","date_created":"2022-05-22T22:01:40Z","page":"1-21","type":"journal_article","department":[{"_id":"KrCh"}],"language":[{"iso":"eng"}],"status":"public","oa":1,"publication_identifier":{"issn":["0022-0000"],"eissn":["1090-2724"]},"month":"11","ec_funded":1,"abstract":[{"text":"Fixed-horizon planning considers a weighted graph and asks to construct a path that maximizes the sum of weights for a given time horizon T. However, in many scenarios, the time horizon is not fixed, but the stopping time is chosen according to some distribution such that the expected stopping time is T. If the stopping-time distribution is not known, then to ensure robustness, the distribution is chosen by an adversary as the worst-case scenario. A stationary plan for every vertex always chooses the same outgoing edge. For fixed horizon or fixed stopping-time distribution, stationary plans are not sufficient for optimality. Quite surprisingly we show that when an adversary chooses the stopping-time distribution with expected stopping-time T, then stationary plans are sufficient. While computing optimal stationary plans for fixed horizon is NP-complete, we show that computing optimal stationary plans under adversarial stopping-time distribution can be achieved in polynomial time.","lang":"eng"}],"arxiv":1,"date_updated":"2025-07-14T09:09:54Z","year":"2022","_id":"11402","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.1802.03642"}],"scopus_import":"1","citation":{"ama":"Chatterjee K, Doyen L.

In this study, we take a novel approach by studying how population structure affects both pairwise identity and the distribution of heterozygosity in a natural population of the self-incompatible plant Antirrhinum majus. Excess variance in heterozygosity between individuals is due to identity disequilibrium, which reflects the variance in inbreeding between individuals; it is measured by the statistic g2. We calculated g2 together with FST and pairwise relatedness (Fij) using 91 SNPs in 22,353 individuals collected over 11 years. We find that pairwise Fij declines rapidly over short spatial scales, and the excess variance in heterozygosity between individuals reflects significant variation in inbreeding. Additionally, we detect an excess of individuals with around half the average heterozygosity, indicating either selfing or matings between close relatives. We use 2 types of simulation to ask whether variation in heterozygosity is consistent with fine-scale spatial population structure. First, by simulating offspring using parents drawn from a range of spatial scales, we show that the known pollen dispersal kernel explains g2. Second, we simulate a 1,000-generation pedigree using the known dispersal and spatial distribution and find that the resulting g2 is consistent with that observed from the field data. In contrast, a simulated population with uniform density underestimates g2, indicating that heterogeneous density promotes identity disequilibrium. Our study shows that heterogeneous density and leptokurtic dispersal can together explain the distribution of heterozygosity."}],"year":"2022","article_number":"iyac083","acknowledged_ssus":[{"_id":"ScienComp"}],"_id":"11411"},{"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1063/5.0097339"}],"scopus_import":"1","citation":{"ieee":"A.

Today's quantum systems are analogous to the ENIAC (Electronic Numerical Integrator And Computer) and EDVAC (Electronic Discrete Variable Automatic Computer) systems of the 1940s, which ran on vacuum tubes. These machines were built on a solid, nominally scalable architecture and when they were developed, nobody could have predicted the development of the transistor and the impact of the resulting semiconductor industry. Simply put, the computers of today are nothing like the early computers of the 1940s. We believe that the qubits of future fault-tolerant quantum systems will look quite different from the qubits of the NISQ machines in operation today. This Special Topic issue is devoted to new and emerging quantum systems with a focus on enabling technologies that can eventually lead to the quantum analog to the transistor. We have solicited both research4–18 and perspective articles19–21 to discuss new and emerging qubit systems with a focus on novel materials, encodings, and architectures. We are proud to present a collection that touches on a wide range of technologies including superconductors,7–13,21 semiconductors,15–17,19 and individual atomic qubits.18\r\n"}],"issue":"19","year":"2022","article_number":"190401","_id":"11417","article_type":"letter_note","article_processing_charge":"No","external_id":{"isi":["000796002100002"]},"quality_controlled":"1","volume":120,"date_created":"2022-05-29T22:01:53Z","publication":"Applied Physics Letters","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"JoFi"}],"publisher":"American Institute of Physics","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","title":"Emerging qubit systems: Guest editorial","acknowledgement":"We would like to thank all of the authors who contributed to\r\nthis Special Topic.

We addressed whether tau elevation affects synaptic transmission at the calyx of Held in slices from mice brainstem. Whole-cell loading of WT human tau (h-tau) in presynaptic terminals at 10–20 µM caused microtubule (MT) assembly and activity-dependent rundown of excitatory neurotransmission. Capacitance measurements revealed that the primary target of WT h-tau is vesicle endocytosis. Blocking MT assembly using nocodazole prevented tau-induced impairments of endocytosis and neurotransmission. Immunofluorescence imaging analyses revealed that MT assembly by WT h-tau loading was associated with an increased MT-bound fraction of the endocytic protein dynamin. A synthetic dodecapeptide corresponding to dynamin 1-pleckstrin-homology domain inhibited MT-dynamin interaction and rescued tau-induced impairments of endocytosis and neurotransmission. We conclude that elevation of presynaptic WT tau induces de novo assembly of MTs, thereby sequestering free dynamins. As a result, endocytosis and subsequent vesicle replenishment are impaired, causing activity-dependent rundown of neurotransmission."}],"intvolume":"        11","citation":{"ama":"Hori T, Eguchi K, Wang HY, et al.

In this work, we take a mean-field view, and consider a two-layer ReLU network trained via noisy-SGD for a univariate regularized regression problem. Our main result is that SGD with vanishingly small noise injected in the gradients is biased towards a simple solution: at convergence, the ReLU network implements a piecewise linear map of the inputs, and the number of “knot” points -- i.e., points where the tangent of the ReLU network estimator changes -- between two consecutive training inputs is at most three. In particular, as the number of neurons of the network grows, the SGD dynamics is captured by the solution of a gradient flow and, at convergence, the distribution of the weights approaches the unique minimizer of a related free energy, which has a Gibbs form. Our key technical contribution consists in the analysis of the estimator resulting from this minimizer: we show that its second derivative vanishes everywhere, except at some specific locations which represent the “knot” points. We also provide empirical evidence that knots at locations distinct from the data points might occur, as predicted by our theory."}],"arxiv":1,"_id":"11420","ddc":["000"],"file_date_updated":"2022-05-30T08:22:55Z","scopus_import":"1","intvolume":"        23","citation":{"chicago":"Shevchenko, Aleksandr, Vyacheslav Kungurtsev, and Marco Mondelli. “Mean-Field Analysis of Piecewise Linear Solutions for Wide ReLU Networks.” <i>Journal of Machine Learning Research</i>.

Since its introduction, the medial axis has been used extensively in many applications as a method of computing a topologically equivalent skeleton. Unfortunately, one limiting factor in the use of the medial axis of a smooth manifold is that it is not necessarily topologically stable under small perturbations of the manifold. To counter these instabilities various prunings of the medial axis have been proposed. Here, we examine one type of pruning, called burning. Because of the good experimental results, it was hoped that the burning method of simplifying the medial axis would be stable. In this work we show a simple example that dashes such hopes based on Bing’s house with two rooms, demonstrating an isotopy of a shape where the medial axis goes from collapsible to non-collapsible.","lang":"eng"}],"_id":"11428"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","edition":"1","publisher":"Springer Nature","publication_identifier":{"issn":["0302-9743"],"eisbn":["9783031062452"],"eissn":["1611-3349"],"isbn":["9783031062445"]},"title":"Web and Wireless Geographical Information Systems","alternative_title":["LNCS"],"month":"05","abstract":[{"lang":"eng","text":"This book constitutes the refereed proceedings of the 18th International Symposium on Web and Wireless Geographical Information Systems, W2GIS 2022, held in Konstanz, Germany, in April 2022.\r\nThe 7 full papers presented together with 6 short papers in the volume were carefully reviewed and selected from 16 submissions.

The surface wave simulation uses the equivalent sources method (ESM) to efficiently animate large bodies of water with precisely controllable wave propagation behavior. The 3D liquid simulator animates complex non-linear fluid behaviors like splashes and breaking waves using off-the-shelf simulators using FLIP or the level set method with semi-Lagrangian advection.\r\nWe combine the two approaches by using the 3D solver to animate localized non-linear behaviors, and the 2D wave solver to animate larger regions with linear surface physics. We use the surface motion from the 3D solver as boundary conditions for 2D surface wave simulator, and we use the velocity and surface heights from the 2D surface wave simulator as boundary conditions for the 3D fluid simulation. We also introduce a novel technique for removing visual artifacts caused by numerical errors in 3D fluid solvers: we use experimental data to estimate the artificial dispersion caused by the 3D solver and we then carefully tune the wave speeds of the 2D solver to match it, effectively eliminating any differences in wave behavior across the boundary. To the best of our knowledge, this is the first time such a empirically driven error compensation approach has been used to remove coupling errors from a physics simulator.\r\nOur coupled simulation approach leverages the strengths of each simulation technique, animating large environments with seamless transitions between 2D and 3D physics.","lang":"eng"}],"issue":"2","year":"2022","month":"05","ec_funded":1,"status":"public","oa":1,"publication_identifier":{"issn":["0167-7055"],"eissn":["1467-8659"]},"oa_version":"Submitted Version","date_published":"2022-05-01T00:00:00Z","publication_status":"published","doi":"10.1111/cgf.14478","citation":{"chicago":"Schreck, Camille, and Chris Wojtan. “Coupling 3D Liquid Simulation with 2D Wave Propagation for Large Scale Water Surface Animation Using the Equivalent Sources Method.” <i>Computer Graphics Forum</i>.

For cubical complexes, the two commonly used constructions (corresponding to direct and indirect digital adjacencies) can give different results for the same image. The two constructions are almost dual to each other, and we use this relationship to extend and modify the cubical complexes to become dual filtered cell complexes. We derive a general relationship between the persistent homology of two dual filtered cell complexes, and also establish how various modifications to a filtered complex change the persistence diagram. Applying these results to images, we derive a method to transform the persistence diagram computed using one type of cubical complex into a persistence diagram for the other construction. This means software for computing persistent homology from images can now be easily adapted to produce results for either of the two cubical complex constructions without additional low-level code implementation.","lang":"eng"}],"arxiv":1,"date_updated":"2022-06-07T08:32:42Z","_id":"11440","place":"Cham","article_processing_charge":"No","editor":[{"full_name":"Gasparovic, Ellen","last_name":"Gasparovic","first_name":"Ellen"},{"full_name":"Robins, Vanessa","first_name":"Vanessa","last_name":"Robins"},{"full_name":"Turner, Katharine","first_name":"Katharine","last_name":"Turner"}],"volume":30,"quality_controlled":"1","external_id":{"arxiv":["2102.11397"]},"publication":"Research in Computational Topology 2","date_created":"2022-06-07T08:21:11Z","page":"1-26","department":[{"_id":"HeEd"}],"language":[{"iso":"eng"}],"type":"book_chapter","title":"The persistent homology of dual digital image constructions","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","edition":"1","publisher":"Springer Nature","series_title":"AWMS","alternative_title":["Association for Women in Mathematics Series"],"day":"27","acknowledgement":"This project started during the Women in Computational Topology workshop held in Canberra in July of 2019.

However, making such materials printable requires painstaking trial-and-error by an expert operator,\r\nas they typically tend to exhibit peculiar rheological or hysteresis properties. Even in the case of successfully finding the process parameters, there is no guarantee of print-to-print consistency due to material differences between batches. These challenges make closed-loop feedback an attractive option where the process parameters are adjusted on-the-fly. There are several challenges for designing an efficient controller: the deposition parameters are complex and highly coupled, artifacts occur after long time horizons, simulating the deposition is computationally costly, and learning on hardware is intractable. In this work, we demonstrate the feasibility of learning a closed-loop control policy for additive manufacturing using reinforcement learning. We show that approximate, but efficient, numerical simulation is\r\nsufficient as long as it allows learning the behavioral patterns of deposition that translate to real-world experiences. In combination with reinforcement learning, our model can be used to discover control policies that outperform\r\nbaseline controllers. Furthermore, the recovered policies have a minimal sim-to-real gap. We showcase this by applying our control policy in-vivo on a single-layer, direct ink writing printer.

To quantify this phenomenon, the extension complexity of a polytope P is defined to be the minimum number of facets of a (possibly higher-dimensional) polytope from which P can be obtained as a (linear) projection. This notion is motivated by its relevance to combinatorial optimisation, and has been studied intensively for various specific polytopes associated with important optimisation problems. In this paper we study extension complexity as a parameter of general polytopes, more specifically considering various families of low-dimensional polytopes. First, we prove that for a fixed dimension d, the extension complexity of a random d-dimensional polytope (obtained as the convex hull of random points in a ball or on a sphere) is typically on the order of the square root of its number of vertices. Second, we prove that any cyclic n-vertex polygon (whose vertices lie on a circle) has extension complexity at most 24√n. This bound is tight up to the constant factor 24. Finally, we show that there exists an no(1)-dimensional polytope with at most n vertices and extension complexity n1−o(1). Our theorems are proved with a range of different techniques, which we hope will be of further interest."}],"year":"2022","_id":"11443","status":"public","publication_identifier":{"issn":["0002-9947"],"eissn":["1088-6850"]},"oa":1,"month":"06"},{"author":[{"full_name":"Chlebak, Clara A","id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","last_name":"Chlebak","first_name":"Clara A","orcid":"0000-0002-3385-3865"},{"full_name":"Reid, Peter H.","last_name":"Reid","first_name":"Peter H."}],"day":"01","title":"From the prefect’s desk: Gerard van Swieten’s library correspondence","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","publisher":"Edinburgh University Press","department":[{"_id":"E-Lib"}],"language":[{"iso":"eng"}],"type":"journal_article","publication":"Library and Information History","page":"23-41","date_created":"2022-06-12T22:01:45Z","quality_controlled":"1","volume":38,"article_type":"original","article_processing_charge":"No","_id":"11444","year":"2022","abstract":[{"lang":"eng","text":"This article investigates library-related documents written by Gerard van Swieten (1700–72) during his tenure as Library Prefect in the Imperial Library of Vienna (1745–72). Van Swieten’s time as Library Prefect is considered through a textual analysis. Handwritten letters were deconstructed in terms of their appearance, layout, and tone in order to mine them for meaning. Furthermore, the contents were examined for library matters such as censorship, catalogues, and collection development. The Imperial Court Library held a prominent role as a repository for rare and valuable works, later becoming the National Library of Austria.\r\nGerard van Swieten’s work as a librarian tends to be overlooked, perhaps because he is better known as the private physician of Maria Theresia, as well as a medical reformer. Nevertheless, he was a hard-working chief librarian deeply involved in all aspects of librarianship. Van Swieten endorsed modern scientific works, which were otherwise banned officially by the censorship commission, for the use of scholars in the library, expanded the collection by acquiring books through his network of scholars and publishers, and reissued library catalogues. He also provided for the comfort of users in the library reading room, at a time when such considerations were unusual. In conclusion, a proposal is made that van Swieten viewed his role as librarian with some importance and pride."}],"issue":"1","date_updated":"2023-02-21T09:51:29Z","month":"04","oa":1,"publication_identifier":{"eissn":["1758-3497"],"issn":["1758-3489"]},"status":"public","date_published":"2022-04-01T00:00:00Z","oa_version":"Submitted Version","doi":"10.3366/lih.2022.0097","publication_status":"published","citation":{"short":"C.A.

However, generalisation of these findings is limited due to scarceness of systematic data on fitness landscapes of proteins with a defined evolutionary relationship. We characterized the fitness peaks of four orthologous fluorescent proteins with a broad range of sequence divergence. While two of the four studied fitness peaks were sharp, the other two were considerably flatter, being almost entirely free of epistatic interactions. Mutationally robust proteins, characterized by a flat fitness peak, were not optimal templates for machine-learning-driven protein design – instead, predictions were more accurate for fragile proteins with epistatic landscapes. Our work paves insights for practical application of fitness landscape heterogeneity in protein engineering.","lang":"eng"}],"date_updated":"2023-08-03T07:20:15Z","year":"2022","acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"Bio"}],"article_number":"75842","_id":"11448","status":"public","publication_identifier":{"issn":["2050-084X"]},"oa":1,"month":"05","ec_funded":1,"doi":"10.7554/elife.75842","publication_status":"published","oa_version":"Published Version","date_published":"2022-05-05T00:00:00Z","file_date_updated":"2022-06-20T07:44:19Z","scopus_import":"1","ddc":["570"],"citation":{"chicago":"Gonzalez Somermeyer, Louisa, Aubin Fleiss, Alexander S Mishin, Nina G Bozhanova, Anna A Igolkina, Jens Meiler, Maria-Elisenda Alaball Pujol, Ekaterina V Putintseva, Karen S Sarkisyan, and Fyodor Kondrashov. “Heterogeneity of the GFP Fitness Landscape and Data-Driven Protein Design.” <i>ELife</i>. eLife Sciences Publications, 2022. <a href=\"https://doi.org/10.7554/elife.75842\">https://doi.org/10.7554/elife.75842</a>.","mla":"Gonzalez Somermeyer, Louisa, et al. “Heterogeneity of the GFP Fitness Landscape and Data-Driven Protein Design.” <i>ELife</i>, vol. 11, 75842, eLife Sciences Publications, 2022, doi:<a href=\"https://doi.org/10.7554/elife.75842\">10.7554/elife.75842</a>.","apa":"Gonzalez Somermeyer, L., Fleiss, A., Mishin, A.

Common genomic alterations involve loss of heterozygosity (LOH). LOH accumulates throughout the genome, offering large encoding capacity for inferring cell lineage. Using only single-cell RNA sequencing (scRNA-seq) of mouse brain cells, we found that LOH events spanning multiple genes are revealed as tracts of monoallelically expressed, constitutionally heterozygous single-nucleotide variants (SNVs). We simultaneously inferred cell lineage and marked developmental time points based on X chromosome inactivation and the total number of LOH events while identifying cell types from gene expression patterns. Our results are consistent with progenitor cells giving rise to multiple cortical cell types through stereotyped expansion and distinct waves of neurogenesis. This type of retrospective analysis could be incorporated into scRNA-seq pipelines and, compared with experimental approaches for determining lineage in model organisms, is applicable where genetic engineering is prohibited, such as humans.","lang":"eng"}],"date_updated":"2023-08-03T07:19:43Z","ec_funded":1,"month":"06","oa":1,"publication_identifier":{"issn":["2405-4712"],"eissn":["2405-4720"]},"status":"public","department":[{"_id":"SiHi"}],"language":[{"iso":"eng"}],"type":"journal_article","publication":"Cell Systems","date_created":"2022-06-19T22:01:57Z","page":"438-453.e5","quality_controlled":"1","volume":13,"external_id":{"isi":["000814124400002"],"pmid":["35452605"]},"article_processing_charge":"No","article_type":"original","author":[{"full_name":"Anderson, Donovan J.","first_name":"Donovan J.","last_name":"Anderson"},{"id":"48EA0138-F248-11E8-B48F-1D18A9856A87","last_name":"Pauler","first_name":"Florian","full_name":"Pauler, Florian"},{"full_name":"Mckenna, Aaron","first_name":"Aaron","last_name":"Mckenna"},{"first_name":"Jay","last_name":"Shendure","full_name":"Shendure, Jay"},{"full_name":"Hippenmeyer, Simon","orcid":"0000-0003-2279-1061","first_name":"Simon","last_name":"Hippenmeyer","id":"37B36620-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Marshall S.","last_name":"Horwitz","full_name":"Horwitz, Marshall S."}],"isi":1,"project":[{"_id":"260018B0-B435-11E9-9278-68D0E5697425","grant_number":"725780","name":"Principles of Neural Stem Cell Lineage Progression in Cerebral Cortex Development","call_identifier":"H2020"},{"_id":"25D92700-B435-11E9-9278-68D0E5697425","grant_number":"LS13-002","name":"Mapping Cell-Type Specificity of the Genomic Imprintome in the Brain"}],"day":"15","pmid":1,"acknowledgement":"D.J.A. thanks Wayne K.
