Description

This class teaches the fundamentals of signals and information theory with emphasis on modeling audio/visual messages and physiologically derived signals, and the human source or recipient. Topics include linear systems, difference equations, Z-transforms, sampling and sampling rate conversion, convolution, filtering, modulation, Fourier analysis, entropy, noise, and Shannon's fundamental theorems. Additional topics may include data compression, filter design, and feature detection. The undergraduate subject MAS.160 meets with the two half-semester graduate subjects MAS.510 and MAS.511, but assignments differ.

Bacteria survive in almost all environments on Earth, including some considered extremely harsh. From the steaming hot springs of Yellowstone to the frozen tundra of the arctic to the barren deserts of Chile, microbes have been found thriving. Their tenacity to survive in such extreme and varied conditions allows them to play fundamental roles in global nutrient cycling. Microbes also cause a wide range of human diseases and can survive inhospitable conditions found in the human body. In this course, we will examine the molecular systems that bacteria use to adapt to changes in their environment. We will consider stresses commonly encountered, such as starvation, oxidative stress and heat shock, and also discuss how the adaptive responses affect the evolution of the bacteria.

Description

The central theme of this course is the interaction of radiation with biological material. The course is intended to provide a broad understanding of how different types of radiation deposit energy, including the creation and behavior of secondary radiations; of how radiation affects cells and why the different types of radiation have very different biological effects. Topics will include: the effects of radiation on biological systems including DNA damage; in vitro cell survival models; and in vivo mammalian systems. The course covers radiation therapy, radiation syndromes in humans and carcinogenesis. Environmental radiation sources on earth and in space, and aspects of radiation protection are also discussed. Examples from the current literature will be used to supplement lecture materi The central theme of this course is the interaction of radiation with biological material.

Description

Bacteria survive in almost all environments on Earth, including some considered extremely harsh. From the steaming hot springs of Yellowstone to the frozen tundra of the arctic to the barren deserts of Chile, microbes have been found thriving. Their tenacity to survive in such extreme and varied conditions allows them to play fundamental roles in global nutrient cycling. Microbes also cause a wide range of human diseases and can survive inhospitable conditions found in the human body. In this course, we will examine the molecular systems that bacteria use to adapt to changes in their environment. We will consider stresses commonly encountered, such as starvation, oxidative stress and heat shock, and also discuss how the adaptive responses affect the evolution of the bacteria.

Description

Dr Gail Carson is Head of ISARIC Coordinating Centre (International Severe Acute Respiratory and Emerging Infection Consortium), a network of networks established in 2011 to ensure a rapid research response to outbreaks of pandemic potential. A quick and efficient response to an outbreak requires strong central communication and coordination. Information needs to be shared quickly and then fed into patient care and policy. A wider approach, cutting across disciplines and specialities, helps limit the number of infected people and the impact on the economy.

Every infection consists of a battle between the invading pathogen and the resisting host. To be successful, a pathogen must escape the many defenses of the host immune system until it can replicate and spread to another host. A pathogen must prevent one of three stages of immune function: detection, activation, or effector function. Examples of disease-specific immune evasion and the mechanisms used by pathogens to prevail over their hosts' immune systems are discussed. Also considered is what these host-pathogen interactions reveal about the normal function of the immune system and basic cell biological processes, such as protein maturation and degradation.

Description

The central theme of this course is the interaction of radiation with biological material. The course is intended to provide a broad understanding of how different types of radiation deposit energy, including the creation and behavior of secondary radiations; of how radiation affects cells and why the different types of radiation have very different biological effects. Topics will include: the effects of radiation on biological systems including DNA damage; in vitro cell survival models; and in vivo mammalian systems. The course covers radiation therapy, radiation syndromes in humans and carcinogenesis. Environmental radiation sources on earth and in space, and aspects of radiation protection are also discussed. Examples from the current literature will be used to supplement lecture materiSubjects
