2 Weak Hanani-Tutte for Monotone Drawings

A drawing of a graph is x-monotone if every edge intersects every vertical line at most once and every vertical line contains at most one vertex. Pach and Tóth showed that if a graph has an x-monotone drawing in which every pair of edges crosses an even number of times, then the graph has an x-monotone embedding in which the x-coordinates of all vertices are unchanged. We give a new proof of this result and strengthen it by showing that the conclusion remains true even if adjacent edges are allowed to cross oddly. This answers a question posed by Pach and Tóth. Moreover, we show that an extension of this result for graphs with non-adjacent pairs of edges crossing oddly fails even if there exists only one such pair in a graph.
Enrollment Levels In Institutions of Higher Education: Are State Lotteries Making A Difference In The American States

The academic literature on the impact of state lotteries on education has dealt primarily with issues of funding. Absent from the literature are studies measuring enrollment numbers before and after the adoption of a state lottery. This study attempts to fill a void in the literature regarding state operated lotteries and enrollments in institutions of higher education by answering the following question: are state operated lotteries increasing the number of higher education students in the American states? Pooled time series cross sectional regression analysis is the methodological technique employed to test the data in this research project. This study suggests that state operated lotteries have not had the impact on enrollments in institutions of higher education that many practitioners and scholars originally anticipated.
Towards Degree Distribution of Duplication Graph Models ∗

We present rigorous and precise analysis of degree distribution in a dynamic graph model known as Pastor-Satorras model in which nodes are added according to a duplication-divergence mechanism. This model is discussed in numerous publications with only very few recent rigorous results, especially for the degree distribution. In this paper we focus on two related problems: the expected degree of a given node over the evolution of the graph and the expected mean degree averaged over all nodes. We present exact and precise asymptotic results showing that both quantities may decrease or increase over time depending on the model parameters. Our findings is a step towards better understanding of the graph behaviors such as degree distributions, symmetry, power law, and structural compression.
Exploration of the pseudospectral method for auralizations

Sound propagation in auralizations can be simulated with geometric or wave-based models. Each one offers particular advantages and disadvantages. Geometric models lead to the ray tracing method and the image source method. Both methods achieve good results for high frequencies and are efficient in large rooms with complex structures, but are not able to represent in a simple manner specific wave phenomena, such as diffraction. Typical wave-based models such as the finite element method, the boundary element method, or the finite difference method are characterized for achieving very precise results for individual frequencies applied to small and moderately sized rooms. A typical disadvantage is the need for high computing power, mainly due to the necessity of running separate simulations for individual frequencies because of numerical dispersion. In this paper, auralizations with the k-space pseudospectral method are explored since it is possible to reduce or eliminate the problem of numerical dispersion with this technique. For certain conditions, complete range impulse response can be obtained from a single simulation execution. The room response, including diffraction and diffusion is analyzed for different scenarios.
SCHEDULING FOR DOWNLINK POWER DOMAIN NOMA

FAIR USER SCHEDULING FOR DOWNLINK POWER DOMAIN NOMA Zafer TOPÇUOĞLU M.S. in Electrical and Electronics Engineering Advisor: Nail AKAR June 2019 Non-Orthogonal Multiple Access (NOMA) has been proposed as a new radio access technique in which multiple users (the case of user pairs or triples are covered in this thesis) are allowed to use the wireless channel simultaneously in a way to improve the overall system capacity. A bucket-based Temporal Fair Scheduling algorithm (TFS) has been proposed in the literature for Orthogonal Multiple Access (OMA) systems. In this thesis, we extend this existing work to downlink power domain NOMA by which user pairs or triples are to be scheduled with the goal of maximizing system capacity under temporal fairness constraints. The effectiveness of the proposed fair user scheduling algorithm for NOMA is validated with simulations in which the effects of transmit power and coverage radius of the base station, as well as the number of users are thoroughly studied.
CAREGIVERS' KNOWLEDGE REGARDING EARLY CHILDHOOD DEVELOPMENT IN SOSHANGUWE, SOUTH AFRICA

A child's caregiver holds the key for successful screening by providing the health professional with accurate information. After delivery of a baby, every mother receives a growth chart that provides a guideline to normal development. Caregivers' competency might be influenced by their macro-social and economic environment. The purpose of the study was to determine caregivers' knowledge regarding early childhood development in a poverty stricken area of Soshanguve. If a lack of knowledge should be identified and be addressed, caregivers' enhanced knowledge of childhood development could enhance early detection and effective treatment of developmental problems. This might help to enhance these children's physical and emotional and intellectual accomplishments throughout their lives. The objectives were to explore caregivers' knowledge of the Road to Health Chart, their understanding of early childhood development and their perceptions regarding the treatment of developmental problems. A quantitative survey was conducted. Self-reported data were gathered by means of structured interviews. Although the respondents had previously received education on the Road to Health Charts, they lacked knowledge regarding development categories, especially language, speech and cognitive development and they expected health services to play a significant role in the treatment of developmental problems. Programmes to provide caregivers with knowledge regarding early childhood development need to be developed and implemented. Early diagnoses of and effective interventions for childhood developmental problems could help children to reach their developmental milestones and to experience fewer problems throughout life.
Cross-sensor iris recognition using adversarial strategy and sensor-specific information

Due to the growing demand of iris biometrics, lots of new sensors are being developed for high-quality image acquisition. However, upgrading the sensor and re-enrolling for users is expensive and time-consuming. This leads to a dilemma where enrolling on one type of sensor but recognizing on the others. For this cross-sensor matching, the large gap between distributions of enrolling and recognizing images usually results in degradation in recognition performance. To alleviate this degradation, we propose Cross-sensor iris network (CSIN) by applying the adversarial strategy and weakening interference of sensor-specific information. Specifically, there are three valuable efforts towards learning discriminative iris features. Firstly, the proposed CSIN adds extra feature extractors to generate residual components containing sensor-specific information and then utilizes these components to narrow the distribution gap. Secondly, an adversarial strategy is borrowed from Generative Adversarial Networks to align feature distributions and further reduce the discrepancy of images caused by sensors. Finally, we extend triplet loss and propose instance-anchor loss to pull the instances of the same class together and push away from others. It is worth mentioning that the proposed method doesn’t need pair-same data or triplet, which reduced the cost of data preparation. Experiments on two real-world datasets validate the effectiveness of the proposed method in cross-sensor iris recognition.
Critical Analysis across Media : Games , Franchises , and the New Cultural Order

This paper argues that Critical Discourse Analysis needs to extend its work to new communications media. I identify the phenomenon of the distributed transmedia franchise as a new kind of inter-medium with significant ideological potential. Some components of transmedia franchises such as immersive worlds and identification through online communities, as well as its ability to continue to present itself to us across many guises, sites, and extended periods of time, may make it a more powerful medium for shaping people’s views of what is natural in the social world than prior media. Finally, I propose a specific analytic model and strategies to enable us to assess the affordances, effects, and dangers of this new inter-medium and its messages.
Precision and Recall : An Ontological Perspective

There is a traditional narrative within information studies regarding precision and recall measures. Precision and recall have been the most commonly used retrieval metrics and are the basis for more complicated and accurate information retrieval evaluations. Relevance, which is the criterion by which both recall and precision are judged, is subject to user interpretation and is context dependent. Although the determination of precision is straightforward, important ambiguities are involved when considering recall. Search evaluation metrics can be parsed into structural components. The interaction of the component parts can be clarified by the application of ontological distinctions. Possibly relevant items not retrieved are most usefully viewed as conceptually dependent parts. Positioned as the denominator of the recall measure, these parts function analogically and are supplemental in character. Although difficult to accurately determine, the recall denominator performs a useful role in the assessment of indexed data structures and other
Supervised vs Unsupervised Methods in Word Sense Disambiguation

Natural language is full of ambiguity. Many words can have different meanings in different contexts. Word Sense Disambiguation (WSD) is the task of determining the correct meaning of an ambiguous word given its context. Two common approaches to WSD are supervised and unsupervised machine learning methods. These two approaches may also be combined to form a third approach, semi-supervised. Supervised methods typically produce the best results, but these methods require labeled training data that may be difficult and expensive to obtain. Consequently, current research is concentrating on semi-supervised and unsupervised methods. In this paper, we survey a supervised, a semisupervised, and an unsupervised approach to WSD in order to compare these different approaches.
Sporobolus spicatus, a potential turf grass under the climatic conditions of United Arab Emirates

Different accessions of Sporobolus spicatus were tested for the possible use in the landscaping sector of United Arab Emirates. In this regards, fifty accessions of S. spicatus were screened against five salinity levels of 15, 30, 45, 60 and 75dSm-1 at 3cm mowing height. Significant variations were found among the treatment for various characters of leaf colour, fresh and dry weight. Most of the accessions of the grass tolerated up to 45 dSm-1, without compromising on quality. Further increase in salinity, most of the accessions ceased to grow, except a few accessions which survived even at salinity levels of 75dSm-1. Many of the grasses exhibit better performance than Paspalam vaginatum, the prevailing commercial turf grass in UAE (used as control in this instance). As a whole accessions 45S, 18S, 35S and 37S showed salinity tolerance at 3cm mowing height and maintaining quality up to the acceptable level. Based on their tolerance to salinity and better performance, these accessions are recommended for turf use in public landscaping.
The Importance of Parental Knowledge and Social Norms: Evidence from Weight Report Cards in Mexico

The rise of childhood obesity in less developed countries is often overlooked. We study the impact of body weight report cards in Mexico. The report cards increased parental knowledge and shifted parental attitudes about children's weight. We observe no meaningful changes in parental behaviors or children's body mass index. Interestingly, parents of children in the most obese classrooms were less likely to report that their obese child weighed too much relative to those in the least obese classrooms. As obesity rates increase, reference points for appropriate body weights may rise, making it more difficult to lower obesity rates.
Explicitly Learning Implicit Classification

With the introduction of SQuAD 2.0 by Rajpurkar et al. [2018], question-answering has become an implicit classification task in which it is just as important to classify unanswerable questions as it is to answer answerable ones. In this paper we explore ways to alleviate implicit classification by treating question-answering as a partial classification problem. We use new data augmentation by Removal of Answer Sentences (RAS) to fix the negative class distribution, but only observe an increased Dev F1 of 76.1 in yes/no-style questions with a downside of increased training time. We test the feasibility of a fine-tuning BERT with just the classification portion of SQuAD 2.0 and observed reduced performance compared to a baseline question-answering model. We find that fine-tuning BERT is very sensitive to changes in training distributions and RAS degrades performance due to differences in context lengths.
SEBUAH LAPORAN KASUS OSTEOGENESIS DISTRACTION USING COMBINED PLATE AND ILIZAROF FIXATOR IN THE TREATMENT OF BONE DEFECT : A CASE REPORT

Osteogenesis distraction and bone transport has been used to reconstruct bone loss defect by allowing new bone to form in the gap. In previous studies, plate-guided bone transport has been successfully to treat bone loss defect in the femur, tibia, and mandible. This study reports a case of fracture of tibia with comminutive bone loss treated with plate fixation and bone transport with Ilizarov ring fixator. At the time of docking, when the transport segment is compressed with bone fragment, the bone fragment is fixed with additional locking or nonlocking screws through the plate. The bone defect size was 7 cm. The lengthening/external fixation index was 12.7 days/cm. In this case there were no shortening that present. The average radiographic consolidation index was 37 days/cm. This case achieved infection-free bone segment regeneration and satisfactorily functional outcome. This technique reduces the duration of external fixation during the consolidation phase, allows correction of length and alignment and provides earlier rehabilitation.
The Effect of Survivors’ Benefits on Poverty and Health Status of Widowed Women: A Turkish Case Study

This study examines the effects of survivor benefits on widowed women’s’ health status and wealth using the Income and Living Conditions Survey (ILCS) in Turkey during the period 2006-2012. A structural Equation Modelling (SEM) is applied, where the causal assumptions from survivor benefits on health and wealth are tested. The results show that those who claim the survivor benefits report a higher health status level by 0.11 units the scale from 1 to 5 than widowed mothers that do not receive the benefits. Examining the sample of those who receive the survivor benefits, a 1 per cent increase in the survivor benefits results to a 2 per cent reduction in poverty.
Analytical Modeling of Mobile Banking Attacks based on a stochastic network conversion technique

Now the quantity and complexity of mobile banking attacks strongly increase. It brings extensive economic damage and requires increase of mobile security level. Development of reliable analytical models that adequately represent real attack implementation processes in different conditions is necessary for effective protection against mobile banking attacks. The paper considers an approach to analytical modeling of mobile banking attacks based on a stochastic network conversion technique. The essence of this technique consists in changeover of a set of elementary branches of a stochastic network by one equivalent branch and the subsequent determination of an equivalent function of the network, and the initial moments and distribution functions of the computer attack implementation time. Advantages of the offered method are the high speed of modeling, high reliability, and high sensitivity of results to initial data change. The experimental assessment of the proposed method has confirmed its sufficiently high efficiency.
A G ] 2 0 Ju n 20 12 Hermitian codes from higher degree places

Matthews and Michel [28] investigated the minimum distances in certain algebraic-geometry codes arising from a higher degree place P . In terms of the Weierstrass gap sequence at P , they proved a bound that gives an improvement on the designed minimum distance. In this paper, we consider those of such codes which are constructed from the Hermitian function field Fq2(H ). We determine the Weierstrass gap sequence G(P ) where P is a degree 3 place of Fq2(H ), and compute the Matthews and Michel bound with the corresponding improvement. We show more improvements using a different approach based on geometry. We also compare our results with the true values of the minimum distances of Hermitian 1-point codes, as well as with estimates due Xing and Chen [32].

The Effect of Nutritional Knowledge on Nutritional Intake in Individuals with Heart Failure

Background: The purpose of this study was to determine the nutritional knowledge of people diagnosed with heart failure (HF) and how it affects their diet adequacy. There are approximately 4.8 million people in the United States living with HF. Less than 15% of people diagnosed with HF survive more than 8 to 12 years, and 80% of males and 70% of females under the age of 65 die within 8 years of diagnosis. For an individual diagnosed with heart failure, the one-year mortality rate is one in five (Nicol, 2002). Adequate knowledge and understanding could play an essential role in improving nutritional status and delaying disease progression in heart failure. Method: A convenience sample of 27 patients (also being used in a primary study) with heart failure (HF) due to coronary heart disease who met the specific inclusion criteria was studied. Sixteen of these individuals also completed the nutritional intake portion of the study. Their diets were analyzed by various valid tools including a detailed 4-day food diary, body weight history, body composition, body mass index (BMI), serum protein, and a questionnaire to assess levels of knowledge in general nutrition and nutritional issues specific to heart failure. Results: Participants scored an average of 55.8% correct (SD= 11.3) on the nutritional knowledge questionnaire. Accuracy ranged from 30.8% to 83.8% on knowledge subscales, but 11 of 12 subscale scores were less than 70%. Various nutrient intake inadequacies were identified, such as greater than 50% of the participants were deficient in calcium, magnesium, and zinc. Also, nine out of the 10 selected nutrients in the study were shown to have some degree of deficiency. An interesting result was that there appeared to be no significant relationship between the important heart failure issue of sodium knowledge and patients’ actual intake of sodium. Conclusion: Heart failure is currently the only cardiovascular disease that is increasing in incidence, mortality, and prevalence. It is the single most common cause of hospital admissions
2019 Method to Decrease the Vertical Distance in Wireless Charging Follow

This publication describes methods to accommodate a decrease in the vertical distance between a power transmitter (PTx) of a wireless power-transfer (WPT) system (e.g., wirelesscharging pad, Qi charger) and a power receiver (PRx) of a user equipment (UE), such as a smartphone, earphones, a smartwatch, and the like. Original design manufacturers (ODMs) design and build increasingly thinner WPT systems and thinner UE. A decrease in the vertical distance between the PTx and the PRx causes an increase in the PTx-to-PRx inductive coupling coefficient (Kc), where 0<Kc<1. Subsequently, the input-to-output voltage gain (AV) is lower, which is not a desirable design. In addition, the range of AV grows tighter, which translates to a poorer response of the PRx output voltage (VOUT) to a PTx switching frequency (fSW). To maintain the same resonant frequency and to accommodate for a decrease in the vertical distance between the PTx and PRx, an ODM can add an external inductance (LExt) that is coupled in series with a leakage inductance (LLeak) of the PRx. In addition, by adding an LExt to the PRx, the ODM of the WPT system can shrink the absolute vertical distance needed between the PRx and PTx and extend the range of the vertical distance needed between the PRx and PTx to maintain the desired output voltage. Therefore, adding an external inductance to the PTx of a WPT system, enables a WPT system ODM and a UE ODM to design and build thinner devices and still maintain, or even increase, the desired output voltage. 2 et al.: Method to Decrease the Vertical Distance in Wireless Charging Published by Technical Disclosure Commons, 2019
