Probing the Response of Two-Dimensional Crystals by Optical Spectroscopy
by Yilei LiThis thesis focuses on the study of the optical response of new atomically thin two-dimensional crystals, principally the family of transition metal dichalcogenides like MoS2. One central theme of the thesis is the precise treatment of the linear and second-order nonlinear optical susceptibilities of atomically thin transition metal dichalcogenides. In addition to their significant scientific interest as fundamental material responses, these studies provide essential knowledge and convenient characterization tools for the application of these 2D materials in opto-electronic devices. Another important theme of the thesis is the valley physics of atomically thin transition metal dichalcogenides. It is shown that the degeneracy in the valley degree of freedom can be lifted and a valley polarization can be created using a magnetic field, which breaks time reversal symmetry in these materials. These findings enhance our basic understanding of the valley electronic states and open up new opportunities for valleytronic applications using two-dimensional materials.
Probing Two-Dimensional Quantum Fluids with Cavity Optomechanics (Springer Theses)
by Yauhen SachkouSuperfluid helium is a quantum liquid that exhibits a range of counter-intuitive phenomena such as frictionless flow. Quantized vortices are a particularly important feature of superfluid helium, and all superfluids, characterized by a circulation that can only take prescribed integer values. However, the strong interactions between atoms in superfluid helium prohibit quantitative theory of vortex behaviour. Experiments have similarly not been able to observe coherent vortex dynamics.This thesis resolves this challenge, bringing microphotonic techniques to bear on two-dimensional superfluid helium, observing coherent vortex dynamics for the first time, and achieving this on a silicon chip. This represents a major scientific contribution, as it opens the door not only to providing a better understanding of this esoteric quantum state of matter, but also to building new quantum technologies based upon it, and to understanding the dynamics of astrophysical superfluids such as those thought to exist in the core of neutron stars.
Probing Unconventional Transport Regimes in Delafossite Metals (Springer Theses)
by Philippa H. McGuinnessThis thesis describes in-depth studies of the remarkable electronic transport within the ultrahigh conductivity delafossite metals PtCoO_2 and PdCoO_2 using the tool of focused ion beam (FIB) microstucturing. Despite being first synthesised over 50 years ago, important questions remain regarding both the origin of the unusually high conductivity of these compounds and the consequences of their unique properties for unconventional electronic transport, such as that within the ballistic regime. The thesis explores both these areas.High-energy electron irradiation is used to examine the effects of deliberately introducing point defects into PdCoO_2 and PtCoO_2, demonstrating that the extremely low resistivity of these materials stems from an extreme purity as high as 1 defect in 120,000 atoms, rather than a novel scattering suppression mechanism. In addition, studies of the electronic transport in micron-scale squares of these metals show that their broadly hexagonal Fermi surfaces lead not only to long range ballistic behaviour but novel ballistic regime phenomena which cannot be observed in materials with a higher-symmetry Fermi surface.
Probiotic Bacteria and Enteric Infections
by J.F.J.G. Koninkx R. Marinsek-Logar J. J. MalagoEvery day many people suffer from intestinal diseases. These disorders can result from pathogens like bacteria, fungi, parasites and viruses, but the causes of non-infectious intestinal disorders and colorectal cancers remain to be elucidated. Disturbances to the normal gut flora (the microbiota) are central to the development of many, if not all, of these disorders. Disturbed gut microbiota is a prelude to public health issues like traveller's-, antibiotic- and Clostridium difficile-associated diarrhoea, irritable bowel syndrome, inflammatory bowel disease, and colorectal cancers. This book discusses the way intestinal disorders affect the microbiota, how the disturbed microbiotal balance leads to enteric disorders and the ways to prevent these disorders. Further his book explores the potential of probiotics (live microorganisms that when ingested bring a health benefit) in treating enteric disorders by analysing the probiotic genome through proteomics, metabolomics and functional assays. Discussed is how the ingestion of specific microorganisms repairs the disturbed microbiota and subsequently ameliorates enteric disorders. Finally this book addresses how genetic engineering and biotechnology will contribute to the development of effective and safe designer probiotics.

Probiotics in Mental Health
by Colin R. Martin Derek LarkinThe concept that the gut and brain are intricately linked is widely accepted not just within the lay community but increasingly within scientific and therapeutic circles as well. Terms such as "heartache" and "gut wrenching" are more than mere metaphor, they represent key fundamental aspects of human experience which all individuals will invariably endure from time to time. The relationship between the gut and brain is complex but fundamental to health and wellbeing. Increasing and compelling evidence supports the existence of a relationship between the health and status of the gut and the manifestation of significant psychopathology. Uniquely within the field of mental health and psychiatry, the role of gut flora and probiotics in both the understanding and treatment of mental illness represents an emerging science whether the potential for therapeutic intervention, through the use of probiotics, offers an opportunity to determine efficacy within a coherent evidence-based model of both action and pathology or, moreover, offers interventions that are comparatively benign compared to the side-effect profile associated with most drugs used to treat mental illness. <P><P>Probiotics in Mental Health examines the role of probiotics in a range of clinical presentations associated with significant psychopathology and facilitates a reconsideration of how mental illness may be conceptualised within a coherent gut-brain model of health and wellbeing. Under the rubric of enhancing wellbeing rather than dwelling on illness and disease, this exciting new volume not only comprises the latest evidence in the field but also advocates an approach characterised by the understanding of mental disorder within an evidence-based model and the pursuit of mental health and wellbeing through the most benign of interventions.

Problem-based Learning: A Research Perspective on Learning Interactions
by Dorothy H. Evensen Cindy E. Hmelo Cindy E. Hmelo-SilverThis volume collects recent studies conducted within the area of medical education that investigate two of the critical components of problem-based curricula--the group meeting and self-directed learning--and demonstrates that understanding these complex phenomena is critical to the operation of this innovative curriculum. It is the editors' contention that it is these components of problem-based learning that connect the initiating "problem" with the process of effective "learning." Revealing how this occurs is the task taken on by researchers contributing to this volume. The studies include use of self-reports, interviews, observations, verbal protocols, and micro-analysis to find ways into the psychological processes and sociological contexts that constitute the world of problem-based learning.
