This seminar was held on March 28 and 29, 1990 at the Senri Hankyu Hotel in Osaka, Japan. The organizers of this seminar were Dr. William F. Benedict, Center for Biotechnol ogy, Baylor College of Medicine, The Woodlands, TX; Dr. Curtis C. Harris, Laboratory of Human Carcinogenesis, Na tional Cancer Institute, Bethesda, MD; and Dr. Hirota Fujiki, Cancer Prevention Division, National Cancer Cente...

Causality violations are typically seen as unrealistic and undesirable features of a physical model. The following points out three reasons why causal-ity violations, which Bonnor and Steadman identified even in solutions to the Ein-stein equation referring to ordinary laboratory situations, are not necessarily undesirable. First, a space-time in which every causal curve can be extended into a ...

Emergence and re-surgence of vector-borne diseases still constitute an important threat to human health in the 21st century, causing over a million death and considerable mortality and morbidity worldwide. Vector-borne diseases are linked to the environment by the ecol‐ ogy of the vectors and of their hosts, including humans. In the recent decades, climate change is a global phenomenon which ha...

With N routers in a network running the OSPF routing protocol a network topol ogy update can generate on the order of N LSA packets This phenomenon known as the LSA N Squared Problem severely degrades network performance and scalability Hierarchical OSPF net work architectures have been proposed to reduce the number of LSAs that are gen erated by a network topology update We show that equal siz...

This paper investigates how the introduction of user fees and defensive expenditures changes the complex dynamics of a discrete-time model, which represents the interaction between visitors and environmental quality in an open-access protected-area OAPA . To investigate this issue more deeply, we begin by studying in great detail the OAPA model, and then we introduce the user fee β and the defe...

Recently, Ott, Grebogi and Yorke (OGY) [6] found an effective method to control chaotic systems to unstable fixed points by using only small control forces; however, OGY's method is based on and limited to a linear theory and requires considerable knowledge of the dynamics of the system to be controlled. In this paper we use two radial basis function networks: one as a model of an unknown plant...

Bone is a complex organ with the capacity to regenerate. Even with this healing potential, healing results in fractured bone are unsatisfactory in a considerable patient cohort even with a good treatment regimen. These delayed healing cases encourage further research into possible new treatment approaches. The recently developed field of osteoimmunol‐ ogy addressing the tight interconnectivity ...

Introduction: Elective waiting lists have become more stretched because of the COVID-19 pandemic and patients evidently been longer for treatment. Patients with high-risk bladder cancer require timely treatment there is strong evidence to suggest that delay in contributes a risk disease progression, metastases death. Studies shown tumour appearances at flexible cystoscopy (FC) can accurately pr...

Philosophy is the field which investigates perspective on and attitude against life in dimensions of logic, values, knowledge existence. It obvious that management, defined as directing management process, involves a philosophical dimension. Main purpose this study to discuss basic issues regarding philosophy context organiza-tional management. The views ontology, epistemology axiol-ogy; nature...

Widespread use of computer networking has resulted in considerable attention being paid to a variety of network-related problems, the generation of efficient multicast trees being one. While many algorithms for generation of multicast trees have been proposed, their relative effectiveness is difficult to assess. Some algorithms have never been implemented. Many have been simulated, but often us...
