None This course provides a detailed examination of the fundamental elements on which computers are based. Topics include number systems and computation, electricity and basic circuits, logic circuits, memory, computer architecture, and operating systems. Operational code and assembly languages are discussed and then implemented on a hardware platform, such as a personal computer or an autonomous vehicle.
Where we are and where we are going" Presented by Prof. John Hill The discovery of superconductivity, the transmission of electrical current with zero energy loss, recently passed its th anniversary.
This truly remarkable property of matter, found at cryogenic temperatures, has made its way into a variety of important uses in modern society, but nature has not yet given us the ultimate practical material that will change the world through its lossless transmission of electrical energy over long distances.
Research on this complex problem in materials science persists in the world at many levels, and progress is continuously made on both scientific and practical fronts, in spite of the impatience that is often displayed by both the scientific and lay public.
In this talk I will briefly describe where we are in this field, and how we got here, and describe the vision that some have had for where we should be going.
Because my personal research is in the discovery of new superconducting materials, only one facet among the larger set of fundamental and practical issues currently under study, the talk will be given from that perspective.
Ben Ocko Access to sustainable sources of clean water is critical to manufacturing, agriculture, energy production, public health, and national security. This field is dominated by polymer-based membranes and has relied on complex, empirically optimized chemistries and structures based on material selections made decades ago.
The resulting processes are energy intensive and suffer from limited performance lifetimes. In this talk, I will describe our recent efforts in synthesizing model membrane materials based on molecular layer-by-layer deposition of aromatic polyamide networks, as well as our measurements of swelling, crosslink density and mechanics of both model and commercial membrane materials.
This understanding will enable industry to develop and manufacture next generation, energy-efficient membrane materials. The sector ID-E microprobe endstation studies a wide range of environmental, earth and planetary problems, requiring a rich array of techniques and instrumentation.
Central to the success of this program is the insertion device and the x-ray optics that produce, monochromate and focus the beam on the sample. All aspects of this system are under review. Design efforts are focused on 1 managing the increased total power and power density of the APS-U undulator source; 2 improved beam and sample stability; 3 improved focusing optics; and 4 rapid and high duty cycle scanning of the incident beam energy.
This is an ongoing development effort with a number of enhancements schedule to be installed in the 1st quarter of Other components are in the design or prototype phase, drawing on collaboration between universities, national labs and industry.
However, there is an opportunity and need for inherently fundamental studies on surface chemistry, physics and structure to elucidate fundamental mechanisms for friction and wear. The non-equilibrium and transient nature of shear-induced changes caused by contacting surfaces in relative motion requires both in situ and ex situ advanced characterization techniques; many of these only available at the light source at Brookhaven.
Ignace Jarrige Different from the simple one-band Hubbard model prediction, it has been recognized that the cuprate superconductors are electron-hole asymmetric. Both these observations are in distinct contrast to that reported on the hole doped side, and brought attention again to the profound electron-hole asymmetry issue in the cuprates.
Taking the advantage of a La2-xCexCuO4 combi-film, namely a film with large range doping gradient distribution, we studied the evolution of the charge and magnetic excitations from optimal- to over-doping systematically in fine steps.
Our results establish the universality of the previous observation for the electron-doped cuprates. And more importantly, the doping dependent evolutions show that the magnetic and charge excitations are not the two faces of a coin.
Rather, the spin-correlation roots in the short range correlation, and the charge-fluctuation stems from long range Coulomb interaction. Ishii et al, Nat. Lee et al, Nat. Ignace Jarrige Nickel-rich lithium transition metal oxides have been recently considered as one of most promising cathode materials for high energy density lithium-ion batteries.
However, the instability of the cathode electrolyte interface has been the major technological barrier for the development of nickel-rich cathodes. The early research has simply assigned this interfacial instability to the electrochemical oxidation of the commonly used carbonate solvents without much discussion on the nature of the parasitic reactions.
A proprietary high precision electrochemical system was built in-house to quantitatively measure the rate and kinetics of the side reactions between the delithiated cathode and the non-aqueous electrolyte.
Our results clearly indicated the dominant chemical reaction within the working potential window is the chemical, not electrochemical, reaction between the intermediate phase of cathode and the electrolyte, generating locally concentrated protons at the surface of the cathode materials.
Figure 1 shows a generic mechanism of parasitic reactions occurring at the interface of cathode materials.
Additional help from advanced characterization tools, such as synchrotron probes, will be also be discussed. John Hill Nudaurelia Capensis?

The multi-arm multi-stage (MAMS) trial is a new paradigm for conducting randomised controlled trials that allows the simultaneous assessment of a number of research treatments against a single control arm.
measured using this method were compared with the analytical solution of the forces between two magnets (with one fixed and the other raster the surface). Measurements and an analytical model present a good agreement. Opportunities in the Hydrologic Sciences.
