Medical Devices: FDA Should Expand Its Consideration of Information Security for Certain Types of Devices

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Several information security threats exist that can exploit vulnerabilities in active implantable medical devices, but experts caution that efforts to mitigate information security risks may adversely affect device performance. Threats to active devices—that is, devices that rely on a power source to operate—that also have wireless capability can be unintentional, such as interference from electromagnet… more

Neutron Coincidence Counting Studies

Description: The efficiency comparison for measured and simulated responses of a 10B-lined proportional counter and a 3He proportional counter in a close, symmetrical geometry are presented. The measurement geometry was modeled in MCNPX to validate the methods used for simulating the response of both the 3He and 10B-lined tubes. The MCNPX models agree within 1% with the 3He tube measurements and within 3% for the 10B-lined tubes when a 0.75-µm boron-metal lining is used.

Assessment of lesser prairie-chicken lek density relative to landscape characteristics in Texas

Description: My 2.5-yr Master'™s project accomplished the objectives of estimating lesser prairie-chicken (LPC) lek density and abundance in the Texas occupied range and modeling anthropogenic and landscape features associated with lek density by flying helicopter lek surveys for 2 field seasons and employing a line-transect distance sampling method. This project was important for several reasons. Firstly, wildlife managers and biologists have traditionally monitored LPC populations with road-based surveys… more

Overview of Phase Space Manipulations of Relativistic Electron Beams

Description: Phase space manipulation is a process to rearrange beam's distribution in 6-D phase space. In this paper, we give an overview of the techniques for tailoring beam distribution in 2D, 4D, and 6D phase space to meet the requirements of various applications. These techniques become a new focus of accelerator physics R&D and very likely these advanced concepts will open up new opportunities in advanced accelerators and the science enabled by them.

Investigating the Magnetorotational Instability with Dedalus, and Open-Souce Hydrodynamics Code

Description: The magnetorotational instability is a fluid instability that causes the onset of turbulence in discs with poloidal magnetic fields. It is believed to be an important mechanism in the physics of accretion discs, namely in its ability to transport angular momentum outward. A similar instability arising in systems with a helical magnetic field may be easier to produce in laboratory experiments using liquid sodium, but the applicability of this phenomenon to astrophysical discs is unclear. To expl… more

Enhanced Growth Rate and Silane Utilization in Amorphous Silicon and Nanocrystalline-Silicon Solar Cell Deposition via Gas Phase Additives

Description: Air Products set out to investigate the impact of additives on the deposition rate of both µCSi and αSi-H films. One criterion for additives was that they could be used in conventional PECVD processing, which would require sufficient vapor pressure to deliver material to the process chamber at the required flow rates. The flow rate required would depend on the size of the substrate onto which silicon films were being deposited, potentially ranging from 200 mm diameter wafers to th… more

Initial Assessment of the Consolidation of Chalcogels into a Viable Waste Form

Description: This report provides some preliminary data for the consolidation of chalcogen-based aerogels. The chalcogels tested to date at PNNL show great promise as iodine sorbents and preliminary consolidation research shows that they can be melted into a phase-pure glass at moderate temperatures. The preliminary consolidation experiments show that these materials might attack fused quartz so an alternative crucible material will likely need to be used to prevent this. The next steps will be to • Conside… more

Cervical SPECT Camera for Parathyroid Imaging

Description: Primary hyperparathyroidism characterized by one or more enlarged parathyroid glands has become one of the most common endocrine diseases in the world affecting about 1 per 1000 in the United States. Standard treatment is highly invasive exploratory neck surgery called “Parathyroidectomy”. The surgery has a notable mortality rate because of the close proximity to vital structures. The move to minimally invasive parathyroidectomy is hampered by the l… more

Analysis of Self-Similar Solutions of Multidimensional Conservation Laws

Description: This project brought large-scale, advanced methods for numerical solution of PDE to bear on the two-dimensional Riemann problem, and obtained numerical solution of problem. This numerical solution allowed us to describe key features of the solution. Analysis was combined with numerical solution to explain these numerical results. High-resolution, large-scale numerical computations show for the #12;first time that a shock forms strictly in the supersonic region. Numerical solutions appear to sho… more

A Comparison of Image Quality Evaluation Techniques for Transmission X-Ray Microscopy

Description: Beamline 6-2c at Stanford Synchrotron Radiation Lightsource (SSRL) is capable of Transmission X-ray Microscopy (TXM) at 30 nm resolution. Raw images from the microscope must undergo extensive image processing before publication. Since typical data sets normally contain thousands of images, it is necessary to automate the image processing workflow as much as possible, particularly for the aligning and averaging of similar images. Currently we align images using the 'phase correlation' algorithm,… more

2012 SRNL-EM VANE RHEOLOGY RESULTS

Description: The vane method has been shown to be an effective tool in measuring the yield stress of both settled and mixed slurries in laboratory bench scale conditions in supporting assessments of both actual and simulant waste slurries. The vane has also been used to characterize dry powders and granular solids, the effect of non-cohesive solids with interstitial fluids and used as a guide to determine if slip is present in the geometries typically used to perform rheological flow curve measurements.

CO{sub 2} Capture from Flue Gas Using Solid Molecular Basket Sorbents

Description: The objective of this project is to develop a new generation of solid, regenerable polymeric molecular basket sorbent (MBS) for more cost-efficient capture and separation of CO{sub 2} from flue gas of coal-fired power plants. The primary goal is to develop a cost-effective MBS sorbent with better thermal stability. To improve the cost-effectiveness of MBS, we have explored commercially available and inexpensive support to replace the more expensive mesoporous molecular sieves like MCM-41 and SB… more
