Storage Class Memory Aware Data Management. (2010)

Storage Class Memory (SCM) is here to stay. It has characteristics that place it in a class apart both from main memory and hard disk drives. Software and systems, architectures and algorithms need to be revisited to extract the maximum benefit from SCM. In this paper, we describe work that is being done in the area of Storage Class Memory aware Data Management at IBM. We specifically cover the challenges in placement of objects in storage and memory systems which have NAND flash (one kind of SCM) in a hierarchy or in the same level with other storage devices. We also focus on the challenges of adapting data structures which are inherently main memory based to work out of a memory hierarchy consisting of DRAM and flash. We describe how these could be addressed for a popular main memory data structure, namely the Bloom filter. 1
The Neurospora rca-1 Gene Complements an Aspergillus flbD Sporulation Mutant but Has No Identifiable Role in Neurospora Sporulation (1998)

The Aspergillus nidulans flbD gene encodes a protein with a Myb-like DNA-binding domain that is proposed to act in concert with other developmental regulators to control initiation of conidiophore development. We have identified a Neurospora crassa gene called rca-1 (regulator of conidiation in Aspergillus) based on its sequence similarity to flbD. We found that N. crassa rca-1 can complement the conidiation defect of an A. nidulans flbD mutant and that induced expression of rca-1 caused conidiation in submerged A. nidulans cultures just as was previously observed for overexpression of flbD. Thus, the N. crassa gene appears to be a functional homologue of A. nidulans flbD and this is the first demonstration of functional complementation of an A. nidulans sporulation defect using a gene from an evolutionarily distant fungus. However, deletion of the rca-1 gene in N. crassa had no major effect on growth rate, macroconidiation, microconidiation, or ascospore formation. The only phenotype displayed by the rca-1 mutant was straight or counterclockwise hyphal growth rather than the clockwise spiral growth observed for wild type. Thus, if rca-1 is involved in N. crassa development, its role is subtle or redundant.
On-site waste ink recycling: Technology evaluation report (1993)

Recycling ink has good potential as a way to reduce waste and promote long-term cost savings. The evaluation summarized here addresses the product quality, waste reduction, and economic issues involved in recycling printing ink in a facility such as The Hartford Courant newspaper in Hartford, CT. The specific unit evaluated is based on the technology of distillation and filtration. Selected performance tests on the waste, recycled, and virgin inks determined product quality. The recycling unit achieved a good product quality of recycled ink, and the recycled ink fared well in such laboratory tests as viscosity, grind, residue, tack, tinting strength, water content, and water pickup. Qualified professionals, in comparisons with newspapers printed with virgin ink, favorably reviewed newspapers printed with recycled ink. Ink and solvent that would have gone to waste were recovered and reused. The resulting cost saving gave a payback period of about 10 years.
Experimental study of the influence of raw material impurities on yellowness index of transesterification polycarbonate (2010)

Abstract This article covers a quantitative experimental study on the influence of raw materials and materials of construction impurities on polycarbonate color as expressed by a solution yellowness index. Major impurities in the production process were identified, synthesized, and spiked into the baseline materials. A fractional factorial experimental design was executed to provide some information of the influence of impurities as corresponding to levels similar to those occurring in the manufacturing practice. Analysis of the experimental design showed that isopropenylphenol (IPP), methoxyphenyl benzoate (MOB) and 9,9‐dimethylxanthene (DMX) are the main producers of color bodies. A quantitative expression was derived which can be used to predict manufacturing problems with regards to color. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Evaluation of Twelve Real-Time Reverse Transcriptase PCR Primer-Probe Sets for Detection of Pandemic Influenza A/H1N1 2009 Virus (2011)

Real-time reverse transcriptase PCR (rRT-PCR) assays have greatly contributed to the detection, control, and prevention of the pandemic influenza A/H1N1 2009 virus. To improve the rRT-PCR assays for detection of pandemic influenza A/H1N1 2009 virus, we evaluated the sensitivity, specificity, and performance of 12 rRT-PCR primer-probe sets [SW (a) to SW (l)] using a panel of virus strains and clinical specimens. These primer-probe sets were derived from published work and designed for detecting the hemagglutinin (HA) or the neuraminidase (NA) gene of the pandemic influenza A/H1N1 2009 virus. A primer-probe set, SW (CDC), developed by the Centers for Disease Control and Prevention (U.S. CDC) to target the HA gene of pandemic influenza A/H1N1 2009 virus, was used as a referee method. Our results demonstrated that although all primer-probe sets in this study had as high as 98.4 to 100% in silico coverage, some of the primer-probe sets had better specificity, sensitivity, and amplification efficiency than others. Two primer-probe sets, SW (h) and SW (l), which target the NA gene of pandemic influenza A/H1N1 2009 virus, were highly sensitive (10(4) copies/reaction), had high detection rates (56/60, P = 0.134, and 59/60, P = 1.000), and showed ideal specificity compared with SW (CDC). In addition, a cocktail of primer-probe sets targeted to the HA and NA genes displayed higher detection sensitivity than primer-probe sets targeting HA or NA alone, indicating that for practical applications, a combination of primer-probes targeting HA and NA genes is the best option for the detection of pandemic influenza A/H1N1 2009 virus.
Study on Model Predictive Speed Control with Position Sensorless Control for PMSMs (2021)

In recent years, permanent magnet synchronous motors (PMSMs) are being widely used in home appliances such as air conditioners and fan motors, vehicles, and railway components. In addition, the application of model predictive control (MPC) to control motors is studied to improve the response of conventional PI controllers. In this study, we derive a responsiveness design method based on predictive horizon in a speed control system that estimates position sensorless control using PMSMs. Furthermore, we combine MPC and position sensorless control by setting the responsiveness of MPC so that there is no interference between current control and position sensorless control.
Information extraction from Wikipedia (2008)

Not only is Wikipedia a comprehensive source of quality information, it has several kinds of internal structure (e.g., relational summaries known as infoboxes), which enable self-supervised information extraction. While previous efforts at extraction from Wikipedia achieve high precision and recall on well-populated classes of articles, they fail in a larger number of cases, largely because incomplete articles and infrequent use of infoboxes lead to insufficient training data. This paper presents three novel techniques for increasing recall from Wikipedia's long tail of sparse classes: (1) shrinkage over an automatically-learned subsumption taxonomy, (2) a retraining technique for improving the training data, and (3) supplementing results by extracting from the broader Web. Our experiments compare design variations and show that, used in concert, these techniques increase recall by a factor of 1.76 to 8.71 while maintaining or increasing precision.
Competing display technologies for the best image performance (2007)

Abstract— Cathode‐ray tubes (CRTs) have been the dominant display technology for years, having the best image performance and low cost. During the last several years, flat‐panel‐display technologies, such as liquid‐crystal displays (LCDs), began to replace the CRT mainly because of its favorable form factor. Today, the image performance of LCDs are equal to that of a CRT, and attractive flat‐display products have become so affordable that they have replaced the CRT from its dominating market position and have obtained the largest market share. In the past, the CRT set the standards for digital imaging technologies, but today, modern image capturing, storage, transport, signal processing, and printing technologies have improved to such high levels that they demand better display technologies and standards. At present, the LCD is at the forefront of this display‐technology evolution. This paper will focus on the latest image‐quality improvements in LCD technology and briefly touch alternatives such as plasma‐display panels (PDP) and microdisplay projection. Special attention will be given to the latest developments in wide‐color‐gamut technologies and methods to reproduce accurate colors within a display device.

A novel energetic composite with a special sandwich microstructure: RDX/expanded graphite intercalation composite (2020)

Abstract In this paper, the RDX/expanded graphite (EG) intercalation composites were prepared by solvent/anti-solvent process to recrystallize RDX crystals into the holes, gaps and grooves of EG with controllable embedding ratio (maximum 87.0 wt%) and crystal size. RDX in the composites was in the most stableα-phase, which was benefit for its further application in the military industry. The stability and sensitivity of RDX were improved with higher melting and thermolysis temperature, activation enthalpy (Δ H ≠ ), critical temperature of thermal explosion ( T b ) and lower mechanical sensitivity. The advanced half-coated parallel multi-sandwiches microstructure of RDX/EG intercalation composites possessed two effects: (i) high heat conduction and (ii) hot spots isolation of the carbon microstructure, which were the key to higher performance.

Viterbi decoding method using channel state information in COFDM system (1999)

A Viterbi decoder using channel state information (CSI) is presented in a digital terrestrial television broadcasting system. The proposed Viterbi decoder uses the CSI derived from the pilots and the CSI is calculated by an interpolation method using the pilots in the receiver. We simulated this method in Rayleigh fading defined in an ETSI standard (ETI 300 744 (1997)). From the simulation, we obtained the results that this method has the better performance of about 0.15 dB to 0.7 dB and 2.2 dB to 2.9 dB in the Rayleigh channel than that of conventional soft decision Viterbi decoding with or without a bit interleaver where constellations are QPSK, 16-QAM and 64-QAM.

Heat Cycle Research Experimental Program, FY-1985 (1985)

Sepsis and bleeding can lead to life-threatening complications, such as stent-graft infection and pseudoaneurysm, after stent-graft implantation. An 83 year-old woman was admitted to our hospital for sepsis 14 months after treatment with a balloon-expandable stent-graft for an arterio-ureteral fistula (AUF) between the right external iliac artery and the right ureter. Blood cultures were positive for methicillin-resistant <i>Staphylococcus aureus</i> and <i>Candida tropicalis</i>. A giant infectious pseudoaneurysm (44 × 70 mm) at the distal edge of the stent-graft was suspected of having caused the sepsis. Although endovascular therapy (EVT) was planned to correct the pseudoaneurysm, the right iliac artery spontaneously became occluded from the ostium of the right common iliac artery to the common femoral artery 5 days after diagnosing the pseudoaneurysm; hence, EVT was not performed. Antibiotic administration was continued, and blood culture results were negative. Although EVT using a stent graft for AUFs is effective, data on the chronic phase outcomes are limited. Therefore, patients with AUFs treated using stent-grafts should be carefully followed up.
Probe Lithography: Probe‐Based 3‐D Nanolithography Using Self‐Amplified Depolymerization Polymers (Adv. Mater. 31/2010) (2010)

Using a heated probe tip a 3D relief replica of the world map with feature sizes as small as 40 nm has been created in a 250 nm thick phthalaldehyde polymer film. The relief structures are created by local evaporation of the polymeric material which decomposes spontaneously into its monomer units upon applying a heat stimulus of microsecond duration. The work, reported on p. 3361 by Armin Knoll, Urs Dürig, and co-workers, opens up new perspectives for probe lithography approaching patterning speeds comparable to electron beam lithography at similar resolution.
Tularemia Outbreaks and Common Vole ( Microtus arvalis ) Irruptive Population Dynamics in Northwestern Spain, 1997–2014 (2015)

During the last decades, large tularemia outbreaks in humans have coincided in time and space with population outbreaks of common voles in northwestern Spain, leading us to hypothesize that this rodent species acts as a key spillover agent of Francisella tularensis in the region. Here, we evaluate for the first time a potential link between irruptive vole numbers and human tularemia outbreaks in Spain. We compiled vole abundance estimates obtained through live-trapping monitoring studies and official reports of human tularemia cases during the period 1997-2014. We confirm a significant positive association between yearly cases of tularemia infection in humans and vole abundance. High vole densities during outbreaks (up to 1000 voles/hectare) may therefore enhance disease transmission and spillover contamination in the environment. If this ecological link is further confirmed, the apparent multiannual cyclicity of common vole outbreaks might provide a basis for forecasting the risk of tularemia outbreaks in northwestern Spain.
Calcium‐dependent stimulation of BALB/c 3T3 mouse cell DNA synthesis by a tumor‐promoting phorbol ester (PMA) (1976)

During the first six passages after their arrival in this laboratory, BALB/c 3T3 mouse cells did not proliferate in serum containing-medium having an ionic calcium concentration of 0.05 mM or less, but by the ninth passage they had become able to multiply in the presence of these lower calcium levels. In low calcium (e.g., 0.02 mM) medium, passage 1-6, cells in sparse cultures were blocked at the Gl/S boundary of their cycle. These blocked cells could be induced to start making DNA within only one hour either by returning the ionic calcium level to a normal range of values (1.25 mM), or by adding 0.05 mug/ml of PMA (12-O-tetradecanoyl-phorbol-13-acetate). PMA probably acted by sensitizing the blocked cells to calcium rather than replacing the ion, because it was ineffective in ionic calcium-free medium. Finally, PMA did not by itself induce proliferation of cells (regardless of the number of passages) which had been proliferatively inactivated by density-dependent factors in confluent cultures. However, PMA did promote DNA synthesis by these cells during their brief transition to the "cycling" state caused by exposure to fresh serum-containing medium.
Measuring usage and adoption of improved cookstoves in Ugandan households using quantitative and qualitative methods (2016)

Improved Cook Stoves (ICSs) present a range of benefits such as decreased fuel consumption and improved air quality. However, in order for these benefits to be realized a household must adopt and consistently use the ICS. This paper documents the first phase of a stove adoption study conducted in Soroti, Uganda with a locally manufactured Tier 2 efficiency cookstove, tested under IWA 11. A market-based approach was used to disseminate ICSs in the local community to a group of 40 participant households. Study participants were divided into three groups non-users, new users and existing users. Initial field interviews were conducted with all participants to understand their perceptions of the stove and reported usage patterns. The most common reason cited for purchasing the stove by new users was fuel savings. Additionally, 130 days of usage was collected using a custom made Stove Use Monitor (SUM). The SUMs indicate that existing users consistently use the ICS. New users exhibit low and inconsistent usage during the initial 35 days of owning the ICS, but within approximately 75 days' increase usage and follow same pattern as the existing user group.
Downscaling Geomechanics Data for Thin Beds Using Petrophysical Techniques (2005)

Abstract Thin-bed sequences, especially those made up of alternating weak and strong sand layers with thickness of less than 1-ft, present a particular challenge in the generation of mechanical earth models (MEMs) for geomechanics design and analyses. Because these beds are thinner than the tool resolution, their heterogeneity and the variations between adjacent layers are often undetected by logging tools normally used to acquire geomechanics data. In other words, these tools cannot resolve the existence of alternating strong and weak sequences; they provide only averaged mechanical properties across these sequences. In one such case, an MEM and sanding study based on wireline sonic data indicated no tendency for sanding across a thick reservoir interval at the drawdowns required for economic oil production. The somewhat flat, log-derived curve of unconfined compressive strength (UCS) indicated that the entire reservoir was above the critical sand-free UCS state; however, laboratory data had revealed a large spread in UCS values, including rock strength values that are indicative of a significant sanding risk. In fact, the field had a history of solids production with depletion. Using the high-resolution images (with vertical resolution of 0.2 in.) provided by a microresistivity imaging tool across the same thin-bed intervals, and using alpha processing and other petrophysical log enhancement to further improve data interpretation, it was possible to generate a high-resolution (around 0.2 in.) porosity log. These downscaling techniques were combined with an empirical UCS-porosity relationship obtained from the available laboratory data. The resulting downscaled UCS log exhibited the wide range of strength values that were known to exist across the thin-bed sequence and were consistent with the history of sand production in the field. The remaining sanding evaluation for the well was completed using this integrated petrophysics and geomechanics approach. When the MEM and sanding analyses were extended to other wells in this field, the results matched well with the actual depletion curves and sanding history data.
Ceramic Coating of Liposomal Gene Carrier for Minimizing Toxicity to Primary Hippocampal Neurons (2013)

Abstract Ceramic-coated liposomes, cerasomes, were used as a new gene carrier for transfecting primary hippocampal neurons, to overcome the fusibility of conventional liposomal carriers. Cerasomes successfully mediated the transfection of primary neurons and minimized toxicity without adverse effects on axonal growth to acquire their unique neuronal morphology.
Using acoustic impulses to detect buried objects (1998)

A detector of nonmetallic buried objects, such as land mines, has been developed using acoustic impulses with a peak energy around 1 kHz. The initial proposal was to compare the difference in signals from two microphones spaced equally on either side of the sound source held a few centimeters above the ground. Ideally, over a uniform surface the difference signal is zero, however, when one microphone is over an object an additional reflected pulse remains after subtraction. In practice, this pulse is small and often obscured by noise. Better results have been obtained if data from a single microphone is subtracted from a ‘‘reference‘‘ waveform. Some problems which have to be overcome are optimizing the alignment of the two pulse trains and deciding whether or not to normalize the signals prior to subtraction. If care is not exercised, either process may distort or mask the required object reflection. This small reflected signal can be further enhanced, compared to the background noise, by correlating with an appropriate known waveform. Mention will also be made of the effects of different media and surface contours.
Channel-stacked NAND flash memory with layer selection by multi-level operation (LSM) (2013)

In this paper, the channel stacked array (CSTAR) NAND flash memory with layer selection by multi-level operation (LSM) of string select transistor (SST) is proposed and investigated to solve problems of conventional channel stacked array. In case of LSM architecture, the stacked layers can be distinguished by combinations of multi-level states of SST and string select line (SSL) bias. Due to the layer selection performed by the bias of SSL, the placement of bit lines and word lines is similar to the conventional planar structure, and proposed CSTAR with LSM has no island-type SSLs. As a result of the advantages of the proposed architecture, various issues of conventional channel stacked NAND flash memory array can be solved.
Coupling surface temperature scanning and ultra-fast adaptive computing to thermally fully characterize complex three-dimensional electronic devices (2006)

A novel analysis engine and experimental system capable of fully characterizing the thermal behavior of complex three-dimensional active submicron electronic devices is introduced in this article. First, the thermoreflectance thermography (TRTG) system is used to measure the 2D surface temperature field of a pulsed device, noninvasively and with submicron spatial resolution. Next, the thermal conductivity of each thin-film layer composing the device is measured and a numerical model is built using measured and known values. The temperature distribution map is then used as input for an ultrafast inverse computational solution to fully characterize the thermal behavior of the complex three-dimensional device under study. By bringing together measurement and computation, it becomes possible for the first time to noninvasively extract the three-dimensional thermal behavior of nanoscale embedded features that cannot otherwise be accessed. The power of the method is demonstrated by verifying that it can extract details of interest of a representative CMOS device
