We consider the problem of finding checkerboard copulas for modeling multivariate distributions.A checkerboard copula is a distribution with a corresponding density defined almost everywhere by a step Spaghetti Lifter function on an m-uniform subdivision of the unit hyper-cube.We develop optimization procedures for finding copulas defined by multip
Recently, compressive sensing (CS) and visual security (VS) have caught researchers attention in information security field.However, the measurement matrix is often reused in CS, which makes it vulnerable to chosen plaintext attack (CPA).In addition, when generating meaningful cipher images, the size of the Siemens ET651HE17E 59cm 4 Burners Ceramic
Despite its declining incidence, gastric cancer (GC) remains a leading cause of cancer-related deaths worldwide.A multimodal approach to GC is critical to ensure optimal patient DIESEL PROTEIN CHOCOLATE outcomes.Pretherapy fine resolution contrast-enhanced cross-sectional imaging, endoscopic ultrasound and staging laparoscopy play an important role
Reassessment of the existing didactic-methodological organization within the University lectures as well as the role of students and University lecturers is a result of the current process of higher education reforms.The advancement BLACK COHOSH ROOT C/S of pedagogical and didactic-methodological competences of university lecturers represents an im
Background: As an acute phase protein, α1-antitrypsin (AAT) has been extensively studied in acute coronary syndrome, but it is unclear whether a relationship exists between AAT and stable angina pectoris (SAP).The purpose of the present study was to investigate the association between AAT plasma levels and SAP.Methods: Overall, 103 SAP patients di
