New results about the structure of plane graphs: A survey

One of the central areas of graph theory is coloring, which is partitioning discrete objects into simpler sub-objects. The development of the theory of planar graphs coloring, as well as that of graph theory as a whole, was initiated by attempts to solve the famous Four Color Problem, solved in 1976 by Appel and Haken. New results on planar graphs coloring are usually based on establishing more subtle structural properties of planar graphs. In 2013–2017, we published with our co-authors 34 papers concerning the structure of paths, faces, stars, and cycles, most of which give tight results. In particular, we have confirmed or disproved several long-stood conjectures.
How to write a bachelor/master thesis

When you write your bachelor or master thesis, probably you have not written many theses like that before in your life. In fact, writing a thesis is very different from attending lectures, going to TA-classes, and doing homework exercises as you did it in the courses that you have taken before. However, many students really like working on their theses and I am sure that you will learn a lot while you do it. In this document, I list some points that can help you while you do the research for your thesis and during the writing process. If you have any suggestions what to add or change in this document, or you have any comments or feedback in general, I am happy to hear from you: andreas.wiese@tum.de.
Tunable InGaN quantum dot microcavity light emitters with 129 nm tuning range from yellow-green to violet

An electrically pumped wavelength-tunable InGaN quantum dot (QD) based microcavity (MC) lighter emitter with a large tuning range of 129 nm was demonstrated. The multi-mode emission spectrum was tuned by injected current from 564 nm (yellow-green) to 435 nm (violet). The MC light emitter is featured with a double dielectric distributed Bragg reflector structure and a copper substrate fabricated using substrate transfer and laser lift off techniques. By utilizing an InGaN QD active layer with a tunable broad emission spectrum and a Fabry-Perot cavity which allows multi-longitudinal mode resonating, the emission spectrum could be tuned among several particular cavity modes, which are decided by the gain enhancement factor. In addition, both the enhancement and suppression of MC emission modes caused by the gain enhancement factor were observed in a single MC device. As the first electrically driven III-V nitride semiconductor based tunable MC light emitter with a tuning range of 129 nm, the device is promis.
Countering Fake News Technically – Detection and Countermeasure Approaches to Support Users 7

The importance of dealing with fake news has increased in both political and social contexts: While existing studies mainly focus on how to detect and label fake news, approaches to help users make their own assessments are largely lacking. This article presents existing black-box and white-box approaches and compares advantages and disadvantages. In particular, white-box approaches show promise in counteracting reactance, while black-box approaches detect fake news with much greater accuracy. We also present the browser plugin TrustyTweet, which we developed to help users evaluate tweets on Twitter by displaying politically neutral and intuitive warnings without generating reactance.
The Whims of Indian Monsoons: Long-term Health Consequences of Early Childhood Exposure to the Indian Drought of 2002

Droughts are recurrent features of the Indian climatic fabric. A single month’s failure (or delay) of the annual monsoon can wield a debilitating blow—in varying degrees—to Indian agriculture and the livelihoods of people, particularly the rural populace. In 2002, large parts of the country experienced one of the most intense droughts recorded in India in the last 25 years. While losses in agricultural income and man-days of rural employment have been widely acknowledged, the long-term health consequences of the drought remain unknown. Combining Young Lives’ longitudinal data from Andhra Pradesh in India, with district-level rainfall data from the Directorate of Economics and Statistics, Government of Andhra Pradesh; this essay provides the first estimates of the long-term impact of the drought on the height attainment of a sub-sample of young individuals from below-poverty line households, who experienced this rainfall shock at the ages of 0-18 months (younger cohort), or 7 - 8.5 years (older cohort). This essay also examines the role of a large-scale rural poverty alleviation program— Indira Kranthi Patham —in mitigating the health impact of the drought for ‘poor’ children.
Enhanced Tissue Classification Based on Multi Attribute Sectional Light Absorption Estimation Using Fuzzy Rule Sets

Tissue classification has become more sophisticated in medical domain where the classification of tissues are performed with the spectra meter. There are many approaches has been discussed for the development of tissue classification, but struggles with the problem of less accuracy and false classification ratio. We propose a multi attribute light absorption estimation technique using fuzzy rule set. The method passes the light from the spectra meter over the tissue and the skin reflects certain amount of light reflected is identified. Also the method computes the area of the tissue and the area of light deployment, the strength of light rays being received. With these features the method computes the region based light absorption by computing the light being received or reflected at each section or region of the tissue image. Using the computed multi attribute sectional light absorption values, the method generates number of rules to perform image classification. At the training phase, the method segments the input set image and for each class of image the method extracts the area of diseased skin, the amount of light being applied and the strength of light being received and so on. The rule set is generated from these data and matched with the input feature vector to compute the similarity which the tissue classification is performed.
Accruals Management and the Financial Performance of Listed Manufacturing Companies in Nigeria

research paper investigated the relationship between accruals management and the financial performance of listed manufacturing companies in Nigeria. In order to achieve the aim of the research, six specific objectives and hypothesis were proposed. Accruals management was measured by discretionary accruals (DACC) and non-discretionary accruals (NDAC) while financial performance was measured by return on assets (ROA); net profit margin (NPM); and return on capital employed (ROCE). Data for the research covered a period of 11 years from 2010 to 2020 for 20listed manufacturing companies - thus comprising 220) firm years. Analytical employed for the purpose of the research included descriptive statistics, Pearson correlation and panel least square (PLS) regression method as well as ADF unit root test. Findings of the research revealed that there is a negative non-significant relationship between discretionary accruals and return on assets; net profit margin; and return on capital employed. And non-significant negative relationship between non-discretionary accruals and return on assets; net profit margin; and return on capital employed. From the findings, it was concluded that both
Supplementary Material for Towards Realistic Long-Tailed Semi-Supervised Learning: Consistency Is All You Need

• CIFAR-10-LT and CIFAR-100-LT: There are 5000 and 500 samples in CIFAR-100 and CIFAR-100 originally, with the image size of 32×32. The entire CIFAR dataset can be downloaded from https:// www.cs. toronto.edu/kriz/cifar.html. We need to manually construct the imbalanced dataset according to N1, M1 (MC for reversed), and the imbalance ratio as we describe in our paper. We calculate the top-1 accuracy for measuring the performance of each method.
Anaemia prevalence may be reduced among countries that fortify ﬂour

The effectiveness of ﬂour fortiﬁcation in reducing anaemia prevalence is equivocal. The goal was to utilise the existing national-level data to assess whether anaemia in non-pregnant women was reduced after countries began fortifying wheat ﬂour, alone or in combination with maize ﬂour, with at least Fe, folic acid, vitamin A or vitamin B 12 . Nationally representative anaemia data were identiﬁed through Demographic and Health Survey reports, the WHO Vitamin and Mineral Nutrition Information System database and other national-level nutrition surveys. Countries with at least two anaemia surveys were considered for inclusion. Within countries, surveys were excluded if altitude was not consistently adjusted for, or if the blood-draw site (e.g. capillary or venous) or Hb quantiﬁcation method (e.g. HemoCue or Cyanmethaemoglobin) differed. Anaemia prevalence was modelled for countries that had pre-and post-fortiﬁcation data ( n 12) and for countries that never fortiﬁed ﬂour ( n 20) using logistic regression models that controlled for time effects, human development index (HDI) and endemic malaria. After adjusting for HDI and malaria, each year of fortiﬁcation was associated with a 2·4% reduction in the odds of anaemia prevalence (PR 0·976, 95% CI 0·975, 0·978). Among countries that never fortiﬁed, no reduction in the odds of anaemia prevalence over time was observed (PR 0·999, 95% CI 0·997, 1·002). Among both fortiﬁcation and non-fortiﬁcation countries, HDI and malaria were signiﬁcantly associated with anaemia ( P , 0·001). Although this type of evidence precludes a deﬁnitive conclusion, results suggest that after controlling for time effects, HDI and endemic malaria, anaemia prevalence has decreased signiﬁcantly in countries that fortify ﬂour with micronutrients, while remaining unchanged in countries that do not.
Abuse Reporting for Metadata-Hiding Communication Based on Secret Sharing

As interest in metadata-hiding communication grows in both research and practice, a need exists for stronger abuse reporting features on metadata-hiding platforms. While message franking has been deployed on major end-to-end encrypted platforms as a lightweight and effective abuse reporting feature, there is no comparable technique for metadata-hiding platforms. Existing efforts to support abuse reporting in this setting, such as asymmetric message franking or the Hecate scheme, require order of magnitude increases in client and server computation or fundamental changes to the architecture of messaging systems. As a result, while metadata-hiding communication inches closer to practice, critical content moderation concerns remain unaddressed. This paper demonstrates that, for broad classes of metadata-hiding schemes, lightweight abuse reporting can be deployed with minimal changes to the overall architecture of the system. Our insight is that much of the structure needed to support abuse reporting already exists in these schemes. By taking a non-generic approach, we can reuse this structure to achieve abuse reporting with minimal overhead. In particular, we show how to modify schemes based on secret sharing user inputs to support a message franking-style protocol. Compared to prior work, our shared franking technique results in a 50% reduction in the time to prepare a franked message and order of magnitude reductions in server-side message processing times, as well as the time to decrypt a message and verify a report.

In the laboratory, understanding the behavioral strategies and neural circuits underlying 12 odor-taxis requires a detailed understanding of the animal’s sensory environment. For small 13 model organisms like C. elegans and larval D. melanogaster , controlling and measuring the odor
SOME LIMIT THEOREMS IN REGRESSION THEORY

SUMMARY. {X,Y) follows an unknown bivariate distribution with 0<JX<^1 and the regression of Y on X is continuous and a sequence of observations on (X,Y) are made. An estimate of the unknown regression function based on these observations and motivated by the method of Fractile Graphical Analysis has been suggested. Its large sample properties, viz., convergence in probability and almost sure uniform convergence to the true regression function have been investigated. Large sample tests for a specified regression function have also been proposed for the case when the conditional variance function of Y on X is known and for the case when it is unknown.
Pilot tests of a PET detector using the TOF-PET ASIC based on monolithic crystals and SiPMs

In this work we show pilot tests of PET detector blocks using the TOF-PET ASIC, coupled to SiPM detector arrays and different crystal configurations. We have characterized the main ASIC features running calibration processes to compensate the time dispersion among the different ASIC/SiPM paths as well as for the time walk on the arrival of optical photons. The aim of this work is to use of LYSO monolithic crystals and explore their photon Depth of Interaction (DOI) capabilities, keeping good energy and spatial resolutions. First tests have been carried out with crystal arrays. Here we made it possible to reach a coincidence resolving times (CRT) of 370 ps FWHM, with energy resolutions better than 20% and resolving well 2 mm sized crystal elements. When using monolithic crystals, a single-pixel LYSO reference crystal helped to explore the CRT performance. We studied different strategies to provide the best timestamp determination in the monolithic scintillator. Times around 1 ns FWHM have been achieved in these pilot studies. In terms of spatial and energy resolution, values of about 3 mm and better than 30% were found, respectively. We have also demonstrated the capability of this system (monolithic and ASIC) to return accurate DOI information.
Simultaneous measurement of the top quark pair production cross-section and Rb in the ATLAS experiment

L’objectiu d’aquesta tesi es mesurar simultaniament la seccio eficac de produccio de parelles t¯t i el coeficient Rb 1 a l’experiment ATLAS de l’LHC, a Ginebra. ATLAS (A Toroidal LHC ApparatuS) es un dels quatre grans experiments que dur a terme noves investigacions sobre la materia, l’energia i el temps en funcionament al Gran Col·lisionador d’Hadrons (LHC) al CERN. ATLAS va ser dissenyat per entendre perque l’Univers es tal com ´es avui en dia. ´Es capac¸ d’examinar els constituents mes intims de la materia mes enlla del que ho ha fet mai cap altre experiment i aixi poder explorar nous fenomens fonamentals. Els descobriments dels secrets de la natura mitjancant les col·lisions de particules dins del detector ATLAS es un desafiament cientific i tecnologic sense precedents a la historia. El detector ATLAS es de gran complexitat, essent el detector mes gran mai construit dins el camp de la fisica de particules. Hi ha diversos processos fisics que tenen estats finals similars a la desintegracio del top (basicament un lepto, quatre jets i energia transversa perduda (MET)) que considerem com a senyal. Com per exemple, la desintregracio dels bosons W i Z a estats finals amb leptons i jets, esdeveniments de QCD que estan formats practicament de jets i MET, etc. Una bona identificacio per una posterior eliminacio d’aquests processos no interessants es de vital importancia per estimar amb una gran precisio els nostres esdeveniments de senyal. Un cop tenim la seleccio del nostre senyal optimitzada per obtenir la maxima puressa de quarks top podem comencar a fer la mesura de la seccio eficac de produccio. Aquesta es fa mitjancant un ”fit” a la distribucio de la massa reconstruida del top hadronic. Aprofitant la gran correlacio que hi ha entre la seccio eficac i el parametre de la matriu CKM (Vtb) hem inclos aquest ultim al fit, donant l’opcio de buscar un limit per nova fisica. Per millorar els errors sistematics (amb 35 pb? 1 era 10% a la seccio eficac) tambe incloem al fit els mateixos errors deixant-los lliures i son les propies dades les que redueixien l’error (amb 1 fb? 1 sera 6% a la seccio eficac). Aixi doncs amb les dades que disposem ( 1 fb? 1) podrem aconseguir la mesura mes precisa (a data d’avui) per la seccio eficac del top quark i el factor Rb que dona molt espai per interpretacions de nova fisica.
~1 kilowatt Ytterbium-doped all-solid photonic bandgap fiber laser

Transverse mode instability (TMI) has been recognized as a major limit to average power scaling of single-mode fiber laser besides the optical nonlinear effects. One key to mitigate TMI is to suppress the higher-order modes (HOMs) propagation in the optical fiber. By implementing additional cores in the optical fiber cladding, HOMs can be resonantly coupled from the main core to the surrounding cladding cores, leading to better HOMs suppression. Here, we demonstrate an Yb-doped multiple-cladding-resonant all-solid photonic bandgap fiber with a ~60μm diameter core for high power fiber lasers. The fiber has a multiple-cladding-resonant design in order to provide better HOMs suppression. Maximum laser power of 910w is achieved for a direct diode-pumped fiber laser without TMI with a 9m long fiber at 60cm coil diameter, breaking the TMI threshold of 800w that has been observed in large-mode-area PCFs with ~40μm core. This result is limited by fiber end burning due to the un-optimized thermal management. Later experiment demonstrates maximum laser power of 1050w with 90% lasing efficiency versus absorbed pump power in a 8m long fiber coiled at 80cm diameter, limited by the pump source. However, the fiber bending condition needs to be optimized in order to produce a better laser beam quality.
Unraveling vagueness: Exploring its puzzles, its nature, and their interplay

This thesis is an investigation into the nature of vagueness, the problems to which it gives rise, and the interplay between these two issues. The two main problems to which vagueness gives rise are the Problem of the Many and the Sorites paradox. The Problem of the Many is generally considered to be a problem specific to objects, arising from their (apparent) vague spatial boundary. The Sorites paradox, while often presented as a paradox concerning vague concepts, is a puzzle for any phenomenon involving vagueness, thereby including the (apparent) vague spatial boundary of objects. As both, distinct, problems potentially arise from the (apparent) vague boundary of objects, this prompts the question of what the relation is between the two puzzles involving vagueness. Considering the absence of this question in the vast collection of literature on vagueness, providing an answer to this question is one of the main aims of this thesis. Surprisingly, this thesis shows that the Sorites paradox and the Problem of the Many are in fact mutually exclusive. In doing so, this thesis provides a novel suggestion of the essential feature that underlies the Sorites paradox and the Problem of the Many, thereby arguing against the generally accepted understanding of both puzzles. Moreover, this thesis provides new insights into how our adopted ontology, and thereby the nature of vagueness, is intertwined with the two puzzles, thereby clarifying the existing literature on vagueness and the solutions to the two puzzles. Finally, this thesis contributes to the debate on the nature of vagueness by (i) providing new insight into the relation between the different kinds of vagueness, (ii) providing an argument establishing that ordinary objects must be vague objects, (iii) discussing the notion of vague identity, and (iii) providing an argument showing that the existence of vague objects does not have to give rise to the vague existence of objects.

The Use of Complementary Therapies for the Reduction of Prescribed Opiate Morphine Milligram Equivalents in Patients Receiving Treatment for Chronic Pain with Comorbid Mood Disorders: A Retrospective

Bilateral ectopic pregnancies, a rare type of heterotopic pregnancy, occur in about 1 in 200,000 pregnancies and 1 in 725 to 1,580 ectopic pregnancies (1). Given the increased number of women undergoing assisted reproductive technology (ART) to achieve fertility, there are a growing number of bilateral ectopic pregnancies being diagnosed. Surgical treatment of bilateral ectopic pregnancies may include linear salpingostomy versus salpingectomy. A less utilized treatment includes direct methotrexate injection into the bilateral fallopian tubes. This case report will detail a bilateral ectopic pregnancy that was diagnosed surgically and confirmed by pathology. The patient desired future fertility, requiring two separate laparoscopic salpingectomies for the most conservative treatment. This led to the diagnosis of the contralateral ectopic pregnancy several days following the initial ectopic pregnancy, which has occurred in multiple other case reports, even delaying diagnosis up to several weeks (5).
Experience with Nerve Allograft Transplantation

Nerve allograft transplantation should be used for the repair of devastating peripheral nerve injuries that cannot be reconstructed through traditional means such as autologous nerve grafting or nerve transfer procedures. The risks of required systemic immunosuppression, although only temporary for nerve allograft recipients, preclude widespread use of this treatment modality. Translational research has led to several advancements in this ﬁeld including the use of preoperative allograft cold preservation in University of Wisconsin organ preservation solution and inclusion of tacrolimus as part of the immunosuppressive regimen. Investigation of how to further diminish nerve allograft immunogenicity, speed neuroregeneration by use of agents such as tacrolimus, and promote preferential motor regeneration will further advance this ﬁeld with the goal of restoring optimal function while minimizing patient morbidity.
Characteristics of group LASSO in handling high correlated data

Problems of high correlated data in a linear regression can not be handled directly by standard methods of parameter estimation such as the least squares (LS). Lasso technique is a proper method to handle this problems. However, lasso may remove some important covariates. Group lasso technique is an extension of the lasso which allegedly be able to overcome it. The study was conducted by creating a simulation to study the characteristics of the group lasso. The simulation results showed the group lasso was better than LS and lasso technique when group of is present included in a group. In other case, group lasso remained the same as LS and lasso.
CHAIN SHIFTS, FEATURE DISTANCE AND CONTRAST PRESERVATION

In this paper I have argued that the Contrast Preservation approach with Neighbours can account for chain shifts with semi-iterative raising only if the attribute of ‘feature distance’ is built into the proposal. This attribute can factor out irrelevant Neighbours in chain shifts, and at the same time it can also predict the right Neighbours. The tool of feature distance evaluates distances in such a way that the minimum difference must be at least the number of unshared features. The data that are currently investigated are from Standard Colloquial Bengali and Cachar Bengali. Extant proposals within the Preserve Contrast approach fail to account for chain shifts adequately and adoption of feature distance leads to a more comprehensive analysis.
