Learning Segmentation from Multiple Datasets with Different Label sets

The thesis deals with the task of object instance segmentation, which aims to learn a per-pixel mask of every object instance of defined classes within an image. Stateof-the-art convolutional neural networks require large quantities of annotated training data. Segmentation masks are costly to annotate.The work focuses on training instance segmentation from multiple datasets with different label sets, and addresses the problem of missing annotations: instances of a class, which are labeled only in some datasets, may be considered the background in a dataset where the class is not labeled. As the main contribution of the thesis, two semi-supervised methods to distinguish between unlabeled instances and background are proposed. One is based on feature similarity of object proposals, second trains a separate classification head for each dataset and uses all heads to discover unlabeled instances. Both methods were implemented as an extension of Mask R-CNN and tested on two splits of the MS COCO dataset: the first divides images into three datasets with overlapping label sets, the second divides images into three datasets with disjoint label sets. On the first split with overlapping labels, the baseline method performed 5% worse in terms of mAP compared to a fully supervised setting. The proposed methods KNN and -MHC improved mAP in the semi-supervised scenario by 1.75% and 0.72% of mAP respectively, which means 35% and 14% increase towards the bound given by full annotation. Interestingly, on the second set with disjoint labels, the proposed methods performed the same as baseline. Analysis of individual errors cases did not show noticeable changes in categorical errors or in the type of errors.
Aesthetic Enhancement via Color Area and Location Awareness

Choosing a suitable color palette can typically improve image aesthetic, where a naive way is choosing harmonious colors from some pre-defined color combinations in color wheels. However, color palettes only consider the usage of color types without specifying their amount in an image. Also, it is still challenging to automatically assign individual palette colors to suitable image regions for maximizing image aesthetic quality. Motivated by these, we propose to construct a contribution-aware color palette from images with high aesthetic quality, enabling color transfer by matching the coloring and regional characteristics of an input image. We hence exploit public image datasets, extracting color composition and embedded color contribution features from aesthetic images to generate our proposed color palettes. We consider both image area ratio and image location as the color contribution features to extract. We have conducted quantitative experiments to demonstrate that our method outperforms existing methods through SSIM (Structural SIMilarity) and PSNR (Peak Signal to Noise Ratio) for objective image quality measurement and no-reference image assessment (NIMA) for image aesthetic scoring.
Factorial Representations of Compact Lie Groups, Wigner Sets and Locally Invariant Quantum Fields

The fibre bundle construct defined in our previous work continues to be the context for this paper; quantum fields composed of fibre algebras become liftings of; or sections through; a fibre bundle with base space a subset of curved space-time. We consider a compact Lie group such as SU(n) acting as a local gauge group of automorphisms of each fibre algebra A(x). Compact Lie groups, represented as gauge groups acting locally on quantum fields, are key elements in electroweak and strong force unification. In our recent joint work we have focused on the translational subgroup of the Poincare group as the generator of local diffeomorphism invariant quantum states. Here we extend those algebraic non-perturbative approaches to address the other half of unification by considering the existence of quantum states of the fibre algebra A(x) invariant to the action of compact non-abelian Lie groups. Wigner sets are complementary to little groups and we prove they have the finite intersection property. Exploiting this then allows us to show that invariant states are common in the sense that the weakly closed convex hull of every normal (density matrix) state contains such an invariant state. From these results and our related research emerges the existence of a locally invariant density matrix quantum state of the field.
Demographic Prisoner's Dilemma : a probabilistic framework

We put a probabilistic framework on the Demographic Prisoner's Dilemma. In this model, cooperating and defecting individuals are placed on a torus to move and play prisoner's dilemma game, if they are on the same site. Each individual accumulates its payoff into a quantity called wealth. If an individual becomes wealthy enough, it can have an offspring. If its wealth becomes negative, it disappears. In this framework we prove that if if the Sucker payoff is far greater than the Reward then for all initial state almost surely all cooperators will die. Moreover if the Temptation payoff (resp. Reward) are far greater than the Punition (resp. Sucker payoff) then for all initial state with positive probability cooperators and defectors live \emph{ad vitam eternam}. We also set a Mean Field model on the demographic prisoner's dilemma and prove on a linearized version of the Mean Field model that with weaker assumptions with positive probability Cooperators live \emph{ad vitam eternam}.

This article aimed to analyze the contribution of the Committee of Sponsoring Organizations (COSO) model components in the internal control of public administration in the municipalities of the state of Santa Catarina. This research is classified as quantitative, descriptive, and survey. The data collection instrument used was a questionnaire with 80 closed questions. The population of this study is the 295 municipalities in the state of Santa Catarina, which resulted in a sample of 295 respondents (responsible for the internal control of each municipality) characterizing a census. The data analysis technique was exploratory factor analysis. As the main result, it was concluded that the five components of the COSO model contribute to the internal control of public administration in the municipalities of the state of Santa Catarina to identify each component's strengths and weaknesses.
Movie moves for singular link cobordisms in 4-dimensional space

Two singular links are cobordant if one can be obtained from the other by singular link isotopy together with a combination of births or deaths of simple unknotted curves, and saddle point transformations. A movie description of a singular link cobordism in 4-space is a sequence of singular link diagrams obtained from a projection of the cobordism into 3-space by taking 2-dimensional cross sections perpendicular to a fixed direction. We present a set of movie moves that are sufficient to connect any two movies of isotopic singular link cobordisms.
Analysis of the Model Designed for Magnetic Resonance Based Wireless Power Transfer Using FEM

Wireless Power Transfer (WPT) applications have been used to provide an efficient energy transfer. With the developing technology, WPT has started to be applied in many areas such as mobile phone charging, electric vehicle charging, lighting and control. The magnetic resonance method is highly preferred for WPT, especially at distances where the air gap is short, due to its features such as high efficiency and little negative impact on the environment. In WPT systems based on this method, a high-efficiency WPT transformer is used to increase system efficiency. In this study, the design and analysis of a WPT system was carried out using the magnetic resonance method. For this purpose, first of all, an original transformer was designed. The windings of the transformer are designed as litz conductors. In order to minimize the leakage fluxes that occur in the transformer, aluminum plates are used on the outer surfaces of the windings to keep the leakage magnetic flux between the windings. Magnetic analyzes of the transformer, modeled with ANSYS-Maxwell based on Finite Element Method (FEM), were carried out and the results obtained were verified with theoretical calculations. Using the results obtained from the magnetic field analysis, it has been seen that the WPT transformer performs power transfer with an efficiency of 95%. The results show that the designed transformer model can be used efficiently in WPT applications.

Efficient Parallel and Approximation Algorithms for Percolation Centrality

Centrality measures on graphs have applications in many domains, including modeling the spread of an infection/disease, social network analysis, and transportation networks. As a result, parallel algorithms for computing various centrality metrics on graphs are gaining significant research attention in recent years. Also, since the networks of importance are extremely large, and the exact computation of the metric requires super-quadratic time, finding efficient algorithms to approximate the measure is essential. We study parallel algorithms for the percolation centrality (PC) measure, which extends the betweenness centrality measure by incorporating a time-dependent state variable with every node. We present parallel algorithms that compute the source-based and source-destination variants of the percolation centrality values of nodes in a network. Our algorithms extend the algorithm of Brandes and introduce optimizations aimed at exploiting the structural properties of graphs. Experimental studies of our algorithms on an Intel Xeon(R) Silver 4116 CPU indicate that our algorithmic techniques offer a significant speedup. We also present a new randomized approximation algorithm, called Dual-Brandes, for the sourcedestination variant of PC for undirected graphs. Our algorithm is inspired by the source-sampling technique developed by Brandes and Pich [5]. We show that the estimates produced by our algorithm are equal to PC in expectation. We also experimentally evaluate our algorithm against baselines based on existing ideas on a collection of 12 real-world graphs. Our algorithm outperforms baselines in accuracy and other metrics. On a fixed sample size of 10% nodes, our algorithm achieves a mean squared error 61% lower than the nearest baseline.
Adherence to Subcutaneous Anti-Tumour Necrosis Factor Treatment in a Cohort of Patients with Rheumatoid Arthritis Before and After the Implementation of a Comprehensive Care Model

Purpose: To assess, in a cohort of patients with rheumatoid arthritis (RA) treated with subcutaneous antitumor necrosis factor drugs (anti-TNFs), the levels of treatment adherence before and after implementing a comprehensive care model (CCM). Patients and Methods: An observational study including RA patients under treatment with subcutaneous anti-TNFs (adalimumab, etanercept, and golimumab) selected at convenience was performed; a sample size of 125 patients was calculated. The outcome variable was adherence assessed with the Compliance Questionnaire on Rheumatology (CQR19), measured before and after implementing a CCM. Descriptive and bivariate analyses were performed comparing adherence before and after applying the model (Wilcoxon and McNemar’s Chi 2 test). For multivariate analysis, a generalized linear model adjusted for covariates was performed, where the difference in the proportion of adherence was the outcome measure. Results: A total of 131 RA patients were followed-up for 24 months; average age was 62 years, and 83.9% were women. The median of DAS28 at the beginning of the follow-up was 2.32, and the HAQ was 0.25. At baseline, 87.8% were adherent; after 24 months, 96.2% were adherent according to CQR19. At the end of follow-up, adherence increased with the three types of anti-TNFs treatment. In a matched model adjusted for clinical variables, the CCM was estimated to produce a 9.4% increase in the total percentage of adherent patients. Additionally, a statistically significant increase of 4.5% in the percentage of adherent patients treated with golimumab compared with etanercept and adalimumab was found. Conclusion: A CCM produced an important increase in the percentage of patients with rheumatoid arthritis adherent to treatment after 24 months of follow-up. It is noteworthy that Golimumab patients were more adherent when compared with other current anti-TNFs treatments.
Talagrand's inequality at higher order and application to Boolean analysis

This note is concerned with an extension, at higher order, of an inequality on the discrete cube $C_n=\{-1,1\}$ with the uniform measure due to Talagrand (\cite{TalL1L2}). As an application, we provide a Theorem in the spirit of a famous result from Kahn, Kalai and Linial (cf. \cite{KKL}) concerning the influence of Boolean functions. We introduce the notion of influence of a couple of coordinate $(i,j)\in\{1,\ldots,n\}^2$ and we proved the following alternative : for any, centered, fonction $f\,:\, C_n\to \{0,1\}$, either there exists a coordinate with influence at least of order $(1/n)^{1/(1+\eta)}$, with $\, 0<\eta<1$ or there exists a couple of coordinate $(i,j)\in\{1,\ldots,n\}^2$, with $i\neq j$, with influence at least of order $(\log n/n)^2$. We also show that this extension of Talagrand's inequality can be obtained for the standard Gaussian measure $\gamma_n$ on $\mathbb{R}^n$ with minor modifications. The obtained inequality can be of independent interest. The arguments rely on interpolation methods by semigroup together with hypercontractive estimates. At the end of this article, we present some related questions to our work and some variations of Kahn, Kalai and Linial's Theorem at order two due to Oleszkiewicz.
Optimizing spectral phase interferometry for direct electric-field reconstruction

Spectral phase interferometry for direct electric-field reconstruction has become a standard technique for the measurement and characterization of extremely short laser pulses. Here we describe an improved setup that employs a planar geometry, uses an interferometrically stable pulse-splitting scheme, and is suitable for broadband pulse characterization up to one optical octave bandwidth and beyond. We devote particular attention to optimization of parameters for the few-cycle regime, resulting in an instrument with an order-of-magnitude sensitivity improvement and a higher spectral resolution than in previous work.
Eleven NanoHUB Simulation Tools Using RASPA Software To Demonstrate Classical Atomistic Simulations of Fluids and Nanoporous Materials

Eleven interactive simulation tools were created on nanoHUB to help users learn how to perform classical atomistic simulations. These tools enable users to perform classical Monte Carlo and molecular dynamics simulations using RASPA software. These tools use comparatively small numbers of production cycles to keep the runtimes short, so that users will not be discouraged by long wait times to see results. Here, we show that these tools produce results of sufficient accuracy and reproducibility for learning purposes. The 11 tools developed were as follows: (1) calculation of the self-diffusion constant of gas molecules in metal–organic frameworks (MOFs), (2) gas adsorption in MOFs using the grand canonical ensemble, (3) Henry’s coefficient calculator for gas molecules in MOFs and a zeolite, (4) adsorption of a gas mixture in a MOF, (5) self-diffusion of a gas mixture in a MOF, (6) void fraction calculation for several MOFs and zeolites, (7) surface area calculation for several MOFs and zeolites, (8) calculation of radial distribution function and self-diffusion constant for several pure gases, (9) energy distribution of adsorption sites using a probe molecule in MOFs, (10) molecular dynamics simulation of pure fluids in the NPT ensemble, and (11) gas adsorption in MOFs using the Gibbs ensemble.
Miyawaki type lift for $GSpin(2,10)$

Let $\frak T_2$ (resp. $\mathfrak{T}$) be the Hermitian symmetric domain of $Spin(2,10)$ (resp. $E_{7,3}$). In the previous work, we constructed holomorphic cusp forms on $\mathfrak{T}$ from elliptic cusp forms with respect to $SL_2(\mathbb{Z})$. By using such cusp forms we construct holomorphic cusp forms on $\mathfrak{T}_2$ which are similar to Miyawaki lift in symplectic groups established by T. Ikeda.
Some Properties of Groups Which Allow Homomorphisms Onto Their Direct Square

Tautological Sheaves: Stability, Moduli Spaces and Restrictions to Generalised Kummer Varieties

Results on stability of tautological sheaves on Hilbert schemes of points are extended to higher dimensions and transferred to abelian surfaces and to the restriction of tautological sheaves to generalised Kummer varieties. This provides a big class of new examples of stable sheaves on higher dimensional irreducible symplectic manifolds. Some aspects of deformations of tautological sheaves are studied.
EFFECT OF PARTIAL REPLACEMENT OF YELLOW CORN BY MANGO SEEDS ON IN VITRO RUMEN DEGRADABILITY, ENERGY CONTENT AND METHANE EMISSION

SUMMARY Mango seeds, which are not consumed by human beings, are a potential feed ingredient, a good source of soluble carbohydrate, protein, and higher fat than corn. This present study objectivewas conducted to examine the effect of replacing yellow corn with mango seed soaked in water (MSSW) in the formulated concentrate mixtures and experimental diets on in vitro gas production and ruminal fermentation. Four formulated concentrate mixtures consisted of 0, 20, 40 and 60% MSSW, referred to as T 0 , T 20 , T 40 and T 60 , respectively. The experimental diets consist of the previous concentrated mixtures with Egyptian clover hay ( CH ) and/or wheat straw (WS), T 0 +CH, T 0 +WS, T 20 +CH, T 20 +WS, T 40 +CH, T 40 +WS, T 60 +CH and T 60 +WS, respectively. The effects of replacement were assessed by incubation of the tested substrates in buffered rumen fluid using an in vitro gas production technique , Metabolizable energy, net energy lactation, total digestible nutrientsand organic matter digestibility (OMD) were calculated from gas production after 24-h incubation. Microbial protein was calculated from OMD. Methane emissionwas high for T 60 and T 60 +WS compared with other tested substrates. In conclusion, the results revealed that replacing up to 60% of corn with MSSW as an alternative energy source could be useful in ruminants feeds.
Floer cohomology of real Lagrangians in the Fermat quintic threefold

Let X be the Fermat quintic threefold. The set of real solutions L forms a Lagrangian submanifold of X. Multiplying the homogeneous coordinates of X by various fifth roots of unity gives automorphisms of X; the images of L under these automorphisms defines a family of 625 different Lagrangian submanifolds, called real Lagrangians. In this paper we try to calculate the Floer cohomology between all pairs of these Lagrangians. We are able to complete most of the calculations, but there are a few cases we cannot do. The basic idea is to explicitly describe some low energy moduli spaces and then use this knowledge to calculate the differential on the E_2 page of the standard spectral sequence for Floer cohomology. It turns out that this is often enough to calculate the cohomology completely. Several techniques are developed to help describe these low energy moduli spaces, including a formula for the Maslov index, a formula for the obstruction bundle, and a way to relate holomorphic strips and discs to holomorphic spheres. The real nature of the Lagrangians is crucial for the development of these techniques.
Sub‐second Lifetime of Photocarriers in Hybrid Lead Halide Perovskite

Recently lead halide perovskite based solar cells have rapidly advanced and their power conversion efficiency (PCE) increased to 25.7%. The progress has been attributed to the super‐long carriers’ lifetime (τ) and long diffusion length (LD) of the photocarriers, however it has been a challenge to precisely characterize and understand the super‐long τ and LD of photocarriers. Here, a MAPbI3 single crystal exhibits four different τ which increase with LD extending from nm scale to mm scale. The prior two lifetimes estimated by transient photoluminescence (TPL) spectra are in the range of ns which comes from the recombination of photocarriers in the tens of nm thick surface layer. In contrast, the third lifetime estimated by transient open‐circuit voltage is hundreds of µs, which is a result of the excess photocarriers diffusing hundreds of µm to electrodes. Finally, the fourth lifetime estimated from the transient photoconductance is as long as sub‐second since the low‐density photocarriers under an electric field drift across the mm‐scale high‐quality single crystal. This study not only clarifies the physical mechanisms of four different lifetimes of photocarriers but also facilitates the design of novel electronics with the halide perovskite semiconductors.
Extension structures and compactifications

Basic results on compactifications are presented applying the notion of extension structure. Each extension structure has a canonical completion. The related completion constructions can be applied, for instance, for generating completion theorems in algebra, lattice theory and general topology, in particular they lead to a universal completion for Cauchy-spaces in the fuzzy filter case. Since compactifications can be identified with special Cauchy-completions, even different types of compactifications can be generated. Among others, we present new results on the Richardson compactification in the fuzzy filter case applying new results on fuzzy filters. This type of compactification was treated previously by the authors (1993).
