Geometric Theory of the Recursion Operators for the Generalized Zakharov-Shabat System in Pole Gauge on the Algebra sl(n,C)

We consider the recursion operator approach to the soliton equations related to the generalized Zakharov-Shabat system on the algebra sl(n,C) in pole gauge both in the general position and in the presence of reductions. We present the recursion operators and discuss their geometric meaning as conjugate to Nijenhuis tensors for a Poisson-Nijenhuis structure defined on the manifold of potentials

Voter Information in the Digital Age: Grading State Election Websites

Voter Information in the Digital Age: Grading State Election Websites examines the extent to which state election websites provide voters with sufficient information to make informed choices. The report assesses the quantity and quality of candidate and ballot measure information offered by the 50 state and District of Columbia election websites and ranks them from one to 51. It recommends a number of best practices currently used by some state or local jurisdictions, as well as innovations on other websites that are used rarely or not at all on state election websites. The authors recommend that states follow new technologies and trends in information delivery and design, and offer voters a full range of candidate and ballot information in innovative formats and media

Temporal Extension of Scale Pyramid and Spatial Pyramid Matching for Action Recognition

Historically, researchers in the field have spent a great deal of effort to create image representations that have scale invariance and retain spatial location information. This paper proposes to encode equivalent temporal characteristics in video representations for action recognition. To achieve temporal scale invariance, we develop a method called temporal scale pyramid (TSP). To encode temporal information, we present and compare two methods called temporal extension descriptor (TED) and temporal division pyramid (TDP) . Our purpose is to suggest solutions for matching complex actions that have large variation in velocity and appearance, which is missing from most current action representations. The experimental results on four benchmark datasets, UCF50, HMDB51, Hollywood2 and Olympic Sports, support our approach and significantly outperform state-of-the-art methods. Most noticeably, we achieve 65.0% mean accuracy and 68.2% mean average precision on the challenging HMDB51 and Hollywood2 datasets which constitutes an absolute improvement over the state-of-the-art by 7.8% and 3.9%, respectively

Sociomedical and psychological aspects of gastric cancer incidence in working age

Despite the recorded in last decades trend of decline in morbidity and mortality from gastric neoplasms, the gastric cancer remains one of the most common causes of death worldwide. Morbidity and mortality are particularly elevated in the active, working age - from 18 to 64 years. Stomach neoplasms have a strong impact on the quality of life of patients, changing their ability to work, social life and attitudes toward family and loved ones. These changed relationships  have also an impact on the social life and status of the patient's relatives.The aim of the study is to present some of the social and psycho-emotional aspects of the gastric cancer morbidity of people in active and working age.The results of the conducted studies proved the connection of the morbidity and mortality from oncological diseases and in particular of the neoplasms of the stomach with the sex and age of the patients. Gastric oncological diseases have a significant negative impact on the psyche, ability to work and social life of patients. The high number of patients in working age is a prerequisite for the implementation in many countries of screening programs for early diagnosis, which is also recommended for the Republic of Bulgaria

Revolution and Transition

Bulgaria’s cultural policy has experienced many transformations since the revolution. One of the most important is that at the beginning the conviction developed that those elements which could not support themselves because of the new market situation made no relevant social contribution. One of the aims of this thesis is to question what the reality of “cultural economy” is and how this is reflected in law-making and life.Die Kulturpolitik Bulgariens nach der Wende hat mehrere Transformationen erlebt. Eine der wichtigsten davon ist, dass sich am Anfang eine Überzeugung entwickelte, dass jene Elemente, die nicht auf Grund der neuen Marktsituation bestehen können, keinen wichtigen gesellschaftlich relevanten Beitrag haben. Diese Studie ist als eine Erhebung der Kulturgeschichte Bulgariens von der Wende bis heute und auch als der Versuch eines Vorausblickes zu verstehen, welche Möglichkeiten der Gestaltung sich in Zukunft ergeben könnten

Remember the Alamo

The purpose of this project was to create a jacket very similar to that worn by the by the Mexican army officers during the 1820s-1830s but with a slightly design twist through the use of vibrant purple accents. It was also an exploration in the combination of traditional embroidery techniques and chemical surface design techniques

Genetic Regulation of Maize and Sorghum under Abiotic Stress

Climate extremes of temperature, drought and flooding continue to challenge global agricultural production and food security. If modeling studies are accurate, climate variability and drought will be a more prevalent occurrence in the future, not only inhibiting grain yield but also stressing water resources. Thus, it is critical to breed for improved climate resilience in agronomic crops and understand the genetic mechanisms conferring adaptation to water-limited environments
