Protecting Big Blue from Rogue Subatomic Particles (2007)

Device technology scaling continues to deliver faster and smaller transistors, contributing to IBMs continued leadership in server systems. However, there is also a dark side to device technology scaling. As transistors shrink, the amount of charge required to change the logic state of a memory or a logic circuit (i.e. flip a 1 to a 0 and vice versa) also shrinks. This complication spurs continued effort at IBM to test, characterize, and mitigate these transient bit flips, so called soft errors. In this paper we survey our ongoing work in this realm and introduce our views on trends for soft errors in future device technologies.
Anytime Point-Based Approximations for Large POMDPs (2006)

The Partially Observable Markov Decision Process has long been recognized as a rich framework for real-world planning and control problems, especially in robotics. However exact solutions in this framework are typically computationally intractable for all but the smallest problems. A well-known technique for speeding up POMDP solving involves performing value backups at specific belief points, rather than over the entire belief simplex. The efficiency of this approach, however, depends greatly on the selection of points. This paper presents a set of novel techniques for selecting informative belief points which work well in practice. The point selection procedure is combined with point-based value backups to form an effective anytime POMDP algorithm called Point-Based Value Iteration (PBVI). The first aim of this paper is to introduce this algorithm and present a theoretical analysis justifying the choice of belief selection technique. The second aim of this paper is to provide a thorough empirical comparison between PBVI and other state-of-the-art POMDP methods, in particular the Perseus algorithm, in an effort to highlight their similarities and differences. Evaluation is performed using both standard POMDP domains and realistic robotic tasks.

Effect of dietary lipids on levels of UDP-glucuronosyltransferase in liver (1992)

Others have shown recently that dietary fish oil protects against acetaminophen-induced liver injury in vivo. Fish oil was protective because it increased the clearance of acetaminophen via glucuronidation. This work left unresolved the basis for increased rates of glucuronidation in animals fed fish oil. We therefore have determined how the amount and type of lipid in the diet affect the activity of liver microsomal UDP-glucuronosyltransferase activity. Male Wistar rats were fed a fat-free diet or isocaloric diets containing 5% corn oil, olive oil or fish oil for 4 weeks. The activity of UDP-glucuronosyltransferase was highest in rats fed fish oil and lowest in rats fed the fat-free diet. Treatment with corn oil and olive oil resulted in intermediate levels of activity. Diet-induced differences in amounts of UDP-glucuronosyltransferase were shown by immunoblotting and kinetic measurements. Treatment with fish oil resulted in a 3-fold increase in the amount of UDP-glucuronosyltransferase versus the fat-free diet. Corn oil and olive oil diets caused 2-fold increases in the amount of UDP-glucuronosyltransferase versus the fat-free diet. Fatty acid analysis of microsomal lipids showed that the fat-free diet was associated with decreased levels of arachidonic acid versus the corn oil or olive oil diets. The fish oil diet resulted in increased levels of omega-3 fatty acids versus the other diets.
Retuning control parameters based on damping assessment (2007)

This paper presents a new approach for tuning damping control parameters to improve large-signal dynamic performance of power systems. It follows two steps, damping assessment and parameter optimization. Prony analysis based on single machine equivalent (SIME) is used for identifying the critical mode and corresponding damping ratio. The damping ratio is an important index for control effect in both small and large signal analysis. If the system is poorly damped after a large disturbance, genetic algorithm (GA) combing with damping assessment procedure as part of the individual evaluation is applied for retuning the control parameters. Test results show that damping assessment extract key information from multi-machine swing curve correctly; the optimized control provides good damping to power system oscillations induced by severe disturbance and makes the system meet preassigned damping performance criterion in large-signal analysis.
Piezoelectric Properties of SrBi<sub>4</sub>Ti<sub>4</sub>O<sub>15</sub>-Based Ceramics (1999)

Piezoelectric properties of lead-free bismuth layer structure oxide, SrBi 4 Ti 4 O 15 (SBT) based ceramics, were studied. By means of La substitution and Mn addition, the maximum value of Q ( Q max ) between resonant frequency and anti-resonant frequency was larger than that of SBT. These materials could be utilized in practical applications as substitutes for lead titanate based ceramics (PT) and lead zirconate titanate based ceramics (PZT) which are used mainly in resonators. The reason for the higher Q max value was identified by microstructual analysis as being due to the absence of a defect structure.
The Photo‐Stability of Polymer Solar Cells: Contact Photo‐Degradation and the Benefits of Interfacial Layers (2012)

Abstract The organic/electrode interfaces in organic solar cells are systematically studied for their light, heat, and electrical stability in an inert atmosphere. Various extraction layers are examined for their effect on device stability, including poly(3,4‐ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) and MoO 3 for hole extraction layers, as well as LiF, Cs 2 CO 3 , and lithium acetylacetonate (Liacac) for electron extraction layers. The organic/metal interface is shown to be inherently photo‐unstable, resulting in significant losses in device efficiency with irradiation. X‐ray photoelectron spectroscopy measurements of the organic/aluminum interface suggest that the photo‐induced changes are chemical in nature. In general, interfacial layers are shown to substantially reduce photo‐degradation of the active layer/electrode interface. In spite of their photo‐stability, several interfacial layers present at the active layer/cathode interface suffer from thermal degradation effects due to temperature increases under exposure to light. Electrical aging effects are proven to be negligible in comparison to other major modes of degradation.
Blood plasma coagulation studied by surface plasmon resonance (1999)

A surface plasmon resonance (SPR) apparatus was used to investigate blood plasma coagulation in real-time as a function of thromboplastin and heparin concentrations. The physical reason for the SPR signal observed is discussed and 3 different models are proposed. The response curves were analyzed by multivariable curve fitting followed by feature extraction. Interesting parameters of the sigmoid curves were lag time, slope and maximum response. When thromboplastin concentrations were increased, the lag-time decreased and the slope of the curve increased. A prolonged clotting time was followed mostly by increased maximum response, with exception for samples with no or very little thromboplastin added. High heparin concentrations changed the clotting kinetics. As seen from the lag-time vs. slope relation. Atomic force microscopy pictures of sensor surfaces dried after completed clotting, revealed differences in fibrin network structures as a function of thromboplastin concentration, and fiber thickness increased with lower thromboplastin concentration. The results correlate well with present common methods.
Wayside Wheel/Rail Load Detector Based Rail Car Preventive Maintenance (2007)

To assess rail car operational performance and to identify poorly performing rail cars early, the Washington Metropolitan Area Transit Authority (WMATA) has acquired and installed a Wayside Wheel/Rail Load Detector (WRLD) and measuring system at one of its yards. The WRLD determines truck performance by measuring lateral loads, vertical loads, and angles of attack (and corresponding derived values such as lateral to vertical (L/V) ratios, speed, average car weight, and total train weight) as vehicles and trains pass the detector. The Association of American Railroads (AAR) introduced this technology in one of its research projects in the 1990s. However, this is the first successful attempt to implement WRLD technology for a transit application. A team of WMATA, Booz Allen Hamilton, and TTCI engineers is working to adapt this technology to be effective in the transit environment. Prior to installing the WRLD, the team performed a VAMPIRE® simulation to predict the range of key parameters that was anticipated at the measurement site and on a representative mainline curve. Real-time data collection and information processing allowed immediate access to the curving performance of individual rail cars. The data was used to assess vehicle dynamic behavior during acceptance testing. Data was stored in a database at the WRLD site, and could be accessed via an Internet link. This data was evaluated for generating performance alarms of poorly performing rail cars — an important project milestone, since gaining maintenance personnel’s confidence in the WRLD’s abilities was one of the major objectives. As an early warning device, the WRLD is a very effective tool to identify and select potential “troublemakers” for inspection and preventive maintenance. In addition, the system is also useful for evaluating selected vehicle series and overall fleet performance, by using median and mean single-wheel L/V ratios.
Differences between papanicolaou smears with correct and incorrect diagnoses (1995)

A case control study of women with carcinoma in situ (CINIII) was undertaken comparing Papanicolaou smears for which false negative reports had been issued with slides for which true positive reports had been made. The number of abnormal cells was the strongest differentiating factor. Where there were less than 50 abnormal cells on the slide, the odds of a false negative report being issued was 23.7 times greater (95% confidence interval 3.7-150) than when there were 200 or more abnormal cells. In false negative slides, the abnormal cells were likely to be not represented throughout the slide, present only as single cells rather than as groups, small in size and with finely granular normochromatic nuclei. We conclude that there are intrinsic differences between true positive and false negative slides. Given these characteristics, rapid rescreening of slides that are considered negative may not be an effective method of reducing the false negative rate.
<title>Dual Mode Calligraphic/Raster Color Cathode Ray Tube (CRT) Projector</title> (1983)

Wider and brighter are key words when describing the wants of users of projection television (TV). Higher resolution and truer colors also rank high on the list of desirable features. In aircraft flight simulators, there is the need for static, and sometimes dynamic, raster shaping for off-axis projection on large dome screens. To top off these conflicting requirements is the need for time shared calligraphic (stroke writing or vector refresh) and raster TV operation in some computer image generation systems. This paper describes some of the concepts being investigated for such a cathode ray tube (CRT) projector. Problems associated with optics, color convergence, cooling of the CRT faceplates and deflection are discussed. In addition, the problems associated with the side-by-side merging of multiple projectors for very wide field of view projection (Videorama) are addressed.
Gas breakthrough experiments on fine‐grained sedimentary rocks (2002)

Abstract The capillary sealing efficiency of fine‐grained sedimentary rocks has been investigated by gas breakthrough experiments on fully water saturated claystones and siltstones (Boom Clay from Belgium, Opalinus Clay from Switzerland and Tertiary mudstone from offshore Norway) of different lithological compositions. Sand contents of the samples were consistently below 12%, major clay minerals were illite and smectite. Porosities determined by mercury injection lay between 10 and 30% while specific surface areas determined by nitrogen adsorption (BET method) ranged from 20 to 48 m 2 g − 1 . Total organic carbon contents were below 2%. Prior to the gas breakthrough experiments the absolute (single phase) permeability ( k abs ) of the samples was determined by steady state flow tests with water or NaCl brine. The k abs values ranged between 3 and 550 nDarcy (3 × 10 −21 and 5.5 × 10 −19 m 2 ). The maximum effective permeability to the gas‐phase ( k eff ) measured after gas breakthrough on initially water‐saturated samples extended from 0.01 nDarcy (1 × 10 −23 m 2 ) up to 1100 nDarcy (1.1 × 10 −18 m 2 ). The residual differential pressures after re‐imbibition of the water phase, referred to as the ‘minimum capillary displacement pressures’ ( P d ), ranged from 0.06 to 6.7 MPa. During the re‐imbibition process the effective permeability to the gas phase decreases with decreasing differential pressure. The recorded permeability/pressure data were used to derive the pore size distribution (mostly between 8 and 60 nm) and the transport porosity of the conducting pore system (10 ‐5 –10 ‐2 %). Correlations could be established between (i) absolute permeability coefficients and the maximum effective permeability coefficients and (ii) effective or absolute permeability coefficients and capillary sealing efficiency. No correlation was found between the capillary displacement pressures determined from gas breakthrough experiments and those derived theoretically by mercury injection.
Ferroelectric domain inversion caused in LiNbO3 plates by heat treatment (1987)

It is demonstrated that heat treatment of a LiNbO3 plate at temperatures somewhat lower than the Curie point causes a ferroelectric domain inversion, thereby yielding an inversion layer useful for various piezoelectric devices. The dependences of the inversion layer thickness on the heat treatment conditions, such as temperature, time, and atmosphere, are experimentally examined. The results show that the domain boundary appears to stop at the median plane of the plate finally. The possible mechanism of the domain inversion is also discussed.
Beta Energy Dependence of LiF:Mg,Cu,P Thermoluminescent Films on Thickness of Sensitive Layer (1992)

The beta energy dependencies of LiF:Mg,Cu,P films has been investigated. LiF:Mg,Cu,P powders of six grain sizes were used for the preparation of the TL films. The film thicknesses are between 1.68 mg.cm-2 and 17.48 mg.cm-2 for the different grain sizes of LiF powder. Experimental results show that the responses for different beta ray sources (90Sr/90Y, 204Tl and 147Pm) were strongly dependent upon the sensitive thickness of the TL films. For the 2.28 mg.cm-2 thickness the TL sensitivity of the film to 147Pm was almost the same as that to 90Sr/90. A flat energy dependence of TL response is possible in a beta energy interval from 0.23 to 2.27 MeV. Experimental details are described.
Primordial Follicle Transplantation within Designer Biomaterial Grafts Produce Live Births in a Mouse Infertility Model (2015)

The gonadotoxic effects of chemotherapy and radiation may result in premature ovarian failure in premenopausal oncology patients. Although autotransplantation of ovarian tissue has led to successful live births, reintroduction of latent malignant cells inducing relapse is a significant concern. In this report, we investigated the design of biomaterial grafts for transplantation of isolated ovarian follicles as a means to preserve fertility. Primordial and primary ovarian follicles from young female mice were extracted and encapsulated into biomaterials for subsequent transplantation into adult mice. Among the formulations tested, aggregated follicles encapsulated within fibrin had enhanced survival and integration with the host tissue following transplantation relative to the fibrin-alginate and fibrin-collagen composites. All mice transplanted with fibrin-encapsulated follicles resumed cycling, and live births were achieved only for follicles transplanted within VEGF-loaded fibrin beads. The extent to which these procedures reduce the presence of metastatic breast cancer cells among the isolated follicles was evaluated, with significantly reduced numbers of cancer cells present relative to intact ovaries. This ability to obtain live births by transplanting isolated primordial and primary follicles, while also reducing the risk of re-seeding disease relative to ovarian tissue transplantation, may ultimately provide a means to preserve fertility in premenopausal oncology patients.

Molecular Diagnosis in Autoimmune Skin Blistering Conditions (2014)

Blister formation in skin and mucous membranes results from a loss of cell-cell or cell-matrix adhesion and is a common outcome of pathological events in a variety of conditions, including autoimmune and genetic diseases, viral and bacterial infections, or injury by physical and chemical factors. Autoantibodies against structural components maintaining cell-cell and cell-matrix adhesion induce tissue damage in autoimmune blistering diseases. Detection of these autoantibodies either tissue-bound or circulating in serum is essential to diagnose the autoimmune nature of disease. Various immunofluorescence methods as well as molecular immunoassays, including enzyme-linked immunosorbent assay and immunoblotting, belong to the modern diagnostic algorithms for these disorders. There is still a considerable need to increase awareness of the rare autoimmune blistering diseases, which often show a severe, chronic-relapsing course, among physicians and the public. This review article describes the immunopathological features of autoimmune bullous diseases and the molecular immunoassays currently available for their diagnosis and monitoring.
Combined doping and geometry effects on transferred-electron bulk instabilities (1971)

The behavior of transferred-electron bulk negative differential conductivity devices with nonuniform geometries and various doping profiles is analyzed. Computer solutions were obtained for appropriate transport equations generalized by a scheme to simulate arbitrary areal variation. The solutions show that the effects of doping and geometrical nonuniformities on domain dynamics are similar. The product of doping and transverse area plays an important role in determining the space-charge properties. An important practical implication of the above result is demonstrated by a scheme for device design using combinations of geometrical and doping nonuniformities to achieve a desired control characteristic. Various equivalent device configurations yielding a linear frequency-voltage characteristic over a wide frequency range are proposed.

Morbidity and quality of life during thermotherapy using magnetic nanoparticles in locally recurrent prostate cancer: Results of a prospective phase I trial (2007)

Interstitial heating using magnetic nanoparticles was feasible and well tolerated in patients with locally recurrent prostate cancer. Deposition of nanoparticles in the prostate was highly durable. Further refinement of the technique is necessary to allow application of higher magnetic field strengths.
Production of Microbial Biomass Protein from Potato Processing Wastes by <i>Cephalosporium eichhorniae</i> (1987)

The use of Cephalosporium eichhorniae 152 (ATCC 38255) (reclassified as Acremonium alabamense; see Addendum in Proof), a thermophilic, acidophilic, amylolytic fungus, for the conversion of potato processing wastes into microbial protein for use as animal feed was studied. The fungus was not inhibited by alpha-solanine or beta-2-chaconine, antimicrobial compounds in potatoes, or by morpholine or cyclohexylamine (additives to steam used in the peeling process) at levels likely to be encountered in this substrate. Mixed effluent from holding tanks at a potato-processing plant contained about 10 bacteria per ml and inhibited fungal growth. The fungus grew well on fresh potato wastes containing up to 5% total carbohydrate and utilized both starch and protein at 45 degrees C and pH 3.75. On potato homogenate medium containing 2% carbohydrate (about 14% fresh potato) supplemented with monoammonium phosphate (0.506 g/liter) and ferric iron (0.1 g/liter), with pH control (at 3.75) and additional nitrogen supplied by the automatic addition of ammonium hydroxide, typical yields were 0.61 g (dry weight) of product and 0.3 g of crude protein per g of carbohydrate supplied. An aerobic, spore-forming bacterium, related to Bacillus brevis, commonly contaminated nonsterilized batch cultures but was destroyed by heating for 15 min at 100 degrees C.
