This project was focused on a basic scientific problem, one that is at the heart of application and development of superconductivity for efficient energy usage. This is improvement in high current density which can only be achieved by learning to pin vortices to the physical structure of its underlying superconducting material. Quantized vortices are the tornado of electrical supercurrents, ubi...

Classic Epidemiology: High-Density Lipoprotein Cholesterol Is a Biomarker of Atherogenic Lipoproteins and Other Major Cardiovascular Risk Factors High-density lipoprotein (HDL) cholesterol is a robust biomarker of atherosclerotic cardiovascular disease (CVD) events. In observational studies and many clinical trials of statin therapy, HDL cholesterol levels are inversely associated with CVD even...

In outlining the physics of neutron stars, and my good fortune in stumbling upon them, I hope that I have given some idea of the interest and rewards of extending physics beyond the confines of laboratories. These are good times in which to be an astrophysicist. I am also deeply aware of my debt to all my colleagues in the Cavendish Laboratory. Firstly to Sir Martin Ryle for his unique flair in...

Small-world networks provide an appealing description of cortical architecture owing to their capacity for integration and segregation combined with an economy of connectivity. Previous reports of low-density interareal graphs and apparent small-world properties are challenged by data that reveal high-density cortical graphs in which economy of connections is achieved by weight heterogeneity an...

Human high-density lipoproteins (HDLs) are involved in the transport of cholesterol. The mechanism by which HDL assembles and functions is not well understood owing to a lack of structural information on circulating spherical HDL. Here, we report a series of molecular dynamics simulations that describe the maturation of discoidal HDL into spherical HDL upon incorporation of cholesterol ester as...

Background: In megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. The use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. In a nuclear reactor, neutron radiation is the most difficult to shield. A method for p...
