--- _id: '197' abstract: - lang: eng text: Modern computer vision systems heavily rely on statistical machine learning models, which typically require large amounts of labeled data to be learned reliably. Moreover, very recently computer vision research widely adopted techniques for representation learning, which further increase the demand for labeled data. However, for many important practical problems there is relatively small amount of labeled data available, so it is problematic to leverage full potential of the representation learning methods. One way to overcome this obstacle is to invest substantial resources into producing large labelled datasets. Unfortunately, this can be prohibitively expensive in practice. In this thesis we focus on the alternative way of tackling the aforementioned issue. We concentrate on methods, which make use of weakly-labeled or even unlabeled data. Specifically, the first half of the thesis is dedicated to the semantic image segmentation task. We develop a technique, which achieves competitive segmentation performance and only requires annotations in a form of global image-level labels instead of dense segmentation masks. Subsequently, we present a new methodology, which further improves segmentation performance by leveraging tiny additional feedback from a human annotator. By using our methods practitioners can greatly reduce the amount of data annotation effort, which is required to learn modern image segmentation models. In the second half of the thesis we focus on methods for learning from unlabeled visual data. We study a family of autoregressive models for modeling structure of natural images and discuss potential applications of these models. Moreover, we conduct in-depth study of one of these applications, where we develop the state-of-the-art model for the probabilistic image colorization task. acknowledgement: I also gratefully acknowledge the support of NVIDIA Corporation with the donation of the GPUs used for this research. alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Alexander full_name: Kolesnikov, Alexander id: 2D157DB6-F248-11E8-B48F-1D18A9856A87 last_name: Kolesnikov citation: ama: Kolesnikov A.

For the computational version of the problem, it is well known that there is no algorithm to decide whether the fundamental group \U0001D70B1(\U0001D44B) of a given finite simplicial complex X is trivial. On the other hand, there are several algorithms that, given a finite simplicial complex X that is simply connected (i.e., with \U0001D70B1(\U0001D44B) \ trivial), compute the higher homotopy group \U0001D70B\U0001D451(\U0001D44B) \ for any given \U0001D451≥2 . However, these algorithms come with a caveat: They compute the isomorphism type of \U0001D70B\U0001D451(\U0001D44B) , \U0001D451≥2 \ as an abstract finitely generated abelian group given by generators and relations, but they work with very implicit representations of the elements of \U0001D70B\U0001D451(\U0001D44B) . Converting elements of this abstract group into explicit geometric maps from the d-dimensional sphere \U0001D446\U0001D451 to X has been one of the main unsolved problems in the emerging field of computational homotopy theory. Here we present an algorithm that, given a simply connected space X, computes \U0001D70B\U0001D451(\U0001D44B) \ and represents its elements as simplicial maps from a suitable triangulation of the d-sphere \U0001D446\U0001D451 to X. For fixed d, the algorithm runs in time exponential in size(\U0001D44B) , the number of simplices of X. Moreover, we prove that this is optimal: For every fixed \U0001D451≥2 , we construct a family of simply connected spaces X such that for any simplicial map representing a generator of \U0001D70B\U0001D451(\U0001D44B) , the size of the triangulation of \U0001D446\U0001D451 on which the map is defined, is exponential in size(\U0001D44B) ." article_type: original author: - first_name: Marek full_name: Filakovský, Marek id: 3E8AF77E-F248-11E8-B48F-1D18A9856A87 last_name: Filakovský - first_name: Peter full_name: Franek, Peter id: 473294AE-F248-11E8-B48F-1D18A9856A87 last_name: Franek orcid: 0000-0001-8878-8397 - first_name: Uli full_name: Wagner, Uli id: 36690CA2-F248-11E8-B48F-1D18A9856A87 last_name: Wagner orcid: 0000-0002-1494-0568 - first_name: Stephan Y full_name: Zhechev, Stephan Y id: 3AA52972-F248-11E8-B48F-1D18A9856A87 last_name: Zhechev citation: ama: Filakovský M, Franek P, Wagner U, Zhechev SY.

Asynchronous programs, on the other hand, are difficult to specify because there are side effects due to pending computation scheduled as a result of the invocation of an operation. They are also difficult to verify because of the large number of possible interleavings of concurrent computation threads. We present synchronization, a new proof rule that simplifies the verification of asynchronous programs by introducing the fiction, for proof purposes, that asynchronous operations complete synchronously. Synchronization summarizes an asynchronous computation as immediate atomic effect. Modular verification is enabled via pending asynchronous calls in atomic summaries, and a complementary proof rule that eliminates pending asynchronous calls when components and their specifications are composed. We evaluate synchronization in the context of a multi-layer refinement verification methodology on a collection of benchmark programs. alternative_title: - LIPIcs article_number: '21' author: - first_name: Bernhard full_name: Kragl, Bernhard id: 320FC952-F248-11E8-B48F-1D18A9856A87 last_name: Kragl orcid: 0000-0001-7745-9117 - first_name: Shaz full_name: Qadeer, Shaz last_name: Qadeer - first_name: Thomas A full_name: Henzinger, Thomas A id: 40876CD8-F248-11E8-B48F-1D18A9856A87 last_name: Henzinger orcid: 0000−0002−2985−7724 citation: ama: 'Kragl B, Qadeer S, Henzinger TA.

Here we demonstrate two-axis control of a spin 3/2 qubit in natural Ge. The qubit is formed in a hut wire double quantum dot device. The Pauli spin blockade principle allowed us to demonstrate electric dipole spin resonance by applying a radio frequency electric field to one of the electrodes defining the double quantum dot. Coherent hole spin oscillations with Rabi frequencies reaching 140 MHz are demonstrated and dephasing times of 130 ns are measured. The reported results emphasize the potential of Ge as a platform for fast and electrically tunable hole spin qubit devices. acknowledged_ssus: - _id: M-Shop - _id: NanoFab article_processing_charge: Yes article_type: original author: - first_name: Hannes full_name: Watzinger, Hannes id: 35DF8E50-F248-11E8-B48F-1D18A9856A87 last_name: Watzinger - first_name: Josip full_name: Kukucka, Josip id: 3F5D8856-F248-11E8-B48F-1D18A9856A87 last_name: Kukucka - first_name: Lada full_name: Vukusic, Lada id: 31E9F056-F248-11E8-B48F-1D18A9856A87 last_name: Vukusic orcid: 0000-0003-2424-8636 - first_name: Fei full_name: Gao, Fei last_name: Gao - first_name: Ting full_name: Wang, Ting last_name: Wang - first_name: Friedrich full_name: Schäffler, Friedrich last_name: Schäffler - first_name: Jian full_name: Zhang, Jian last_name: Zhang - first_name: Georgios full_name: Katsaros, Georgios id: 38DB5788-F248-11E8-B48F-1D18A9856A87 last_name: Katsaros orcid: 0000-0001-8342-202X citation: ama: Watzinger H, Kukucka J, Vukušić L, et al.

Although much of the signal cascade regulating myosin activity has been characterized, the origin of such oscillatory behavior is still unclear. Here, we show that basal myosin II oscillation in Drosophila ovarian epithelium is not controlled by actomyosin cortical tension, but instead relies on a biochemical oscillator involving ROCK and myosin phosphatase. Key to this oscillation is a diffusive ROCK flow, linking junctional Rho1 to medial actomyosin cortex, and dynamically maintained by a self-activation loop reliant on ROCK kinase activity. In response to the resulting myosin II recruitment, myosin phosphatase is locally enriched and shuts off ROCK and myosin II signals. Coupling Drosophila genetics, live imaging, modeling, and optogenetics, we uncover an intrinsic biochemical oscillator at the core of myosin II regulatory network, shedding light on the spatio-temporal dynamics of force generation. article_number: '1210' article_processing_charge: No author: - first_name: Xiang full_name: Qin, Xiang last_name: Qin - first_name: Edouard B full_name: Hannezo, Edouard B id: 3A9DB764-F248-11E8-B48F-1D18A9856A87 last_name: Hannezo orcid: 0000-0001-6005-1561 - first_name: Thomas full_name: Mangeat, Thomas last_name: Mangeat - first_name: Chang full_name: Liu, Chang last_name: Liu - first_name: Pralay full_name: Majumder, Pralay last_name: Majumder - first_name: Jjiaying full_name: Liu, Jjiaying last_name: Liu - first_name: Valerie full_name: Choesmel Cadamuro, Valerie last_name: Choesmel Cadamuro - first_name: Jocelyn full_name: Mcdonald, Jocelyn last_name: Mcdonald - first_name: Yinyao full_name: Liu, Yinyao last_name: Liu - first_name: Bin full_name: Yi, Bin last_name: Yi - first_name: Xiaobo full_name: Wang, Xiaobo last_name: Wang citation: ama: Qin X, Hannezo EB, Mangeat T, et al.

Such methods are particularly problematic in posterior cortical regions (e.g. visual cortex), where sectioning leads to significant damage and distortion of tissue. Even more challenging is the post hoc localization of micro-electrodes, which relies on the same techniques, suffers from similar drawbacks and requires even higher precision. Here, we propose a new, simple method for quantitative lesion characterization and electrode localization that is less labor-intensive and yields more detailed results than conventional methods. We leverage staining techniques standard in electron microscopy with the use of commodity micro-CT imaging. We stain whole rat and zebra finch brains in osmium tetroxide, embed these in resin and scan entire brains in a micro-CT machine. The scans result in 3D reconstructions of the brains with section thickness dependent on sample size (12–15 and 5–6 microns for rat and zebra finch respectively) that can be segmented manually or automatically. Because the method captures the entire intact brain volume, comparisons within and across studies are more tractable, and the extent of lesions and electrodes may be studied with higher accuracy than with current methods. article_number: '5184' article_processing_charge: No author: - first_name: Javier full_name: Masís, Javier last_name: Masís - first_name: David full_name: Mankus, David last_name: Mankus - first_name: Steffen full_name: Wolff, Steffen last_name: Wolff - first_name: Grigori full_name: Guitchounts, Grigori last_name: Guitchounts - first_name: Maximilian A full_name: Jösch, Maximilian A id: 2BD278E6-F248-11E8-B48F-1D18A9856A87 last_name: Jösch orcid: 0000-0002-3937-1330 - first_name: David full_name: Cox, David last_name: Cox citation: ama: Masís J, Mankus D, Wolff S, Guitchounts G, Jösch MA, Cox D.

Deregulated mRNA levels of DNA repair and ribosomal protein genes in an Arabidopsis arm mutant suggest non-telomeric ARM function. The human homolog ARMC6 interacts with hTRF2. Abstract: Telomerase maintains telomeres and has proposed non-telomeric functions. We previously identified interaction of the C-terminal domain of Arabidopsis telomerase reverse transcriptase (AtTERT) with an armadillo/β-catenin-like repeat (ARM) containing protein. Here we explore protein–protein interactions of the ARM protein, AtTERT domains, POT1a, TRF-like family and SMH family proteins, and the chromatin remodeling protein CHR19 using bimolecular fluorescence complementation (BiFC), yeast two-hybrid (Y2H) analysis, and co-immunoprecipitation. The ARM protein interacts with both the N- and C-terminal domains of AtTERT in different cellular compartments. ARM interacts with CHR19 and TRF-like I family proteins that also bind AtTERT directly or through interaction with POT1a. The putative human ARM homolog co-precipitates telomerase activity and interacts with hTRF2 protein in vitro. Analysis of Arabidopsis arm mutants shows no obvious changes in telomere length or telomerase activity, suggesting that ARM is not essential for telomere maintenance. The observed interactions with telomerase and Myb-like domain proteins (TRF-like family I) may therefore reflect possible non-telomeric functions. Transcript levels of several DNA repair and ribosomal genes are affected in arm mutants, and ARM, likely in association with other proteins, suppressed expression of XRCC3 and RPSAA promoter constructs in luciferase reporter assays. In conclusion, ARM can participate in non-telomeric functions of telomerase, and can also perform its own telomerase-independent functions.' article_processing_charge: No article_type: original author: - first_name: Ladislav full_name: Dokládal, Ladislav last_name: Dokládal - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: David full_name: Honys, David last_name: Honys - first_name: Nikoleta full_name: Dupláková, Nikoleta last_name: Dupláková - first_name: Lan full_name: Lee, Lan last_name: Lee - first_name: Stanton full_name: Gelvin, Stanton last_name: Gelvin - first_name: Eva full_name: Sýkorová, Eva last_name: Sýkorová citation: ama: Dokládal L, Benková E, Honys D, et al.
