Micro-pages (2010)

Power consumption and DRAM latencies are serious concerns in modern chip-multiprocessor (CMP or multi-core) based compute systems. The management of the DRAM row buffer can significantly impact both power consumption and latency. Modern DRAM systems read data from cell arrays and populate a row buffer as large as 8 KB on a memory request. But only a small fraction of these bits are ever returned back to the CPU. This ends up wasting energy and time to read (and subsequently write back) bits which are used rarely. Traditionally, an open-page policy has been used for uni-processor systems and it has worked well because of spatial and temporal locality in the access stream. In future multi-core processors, the possibly independent access streams of each core are interleaved, thus destroying the available locality and significantly under-utilizing the contents of the row buffer. In this work, we attempt to improve row-buffer utilization for future multi-core systems.
A new substrate engineering for the formation of empty space in silicon (ESS) induced by silicon surface migration (2003)

A new technique to form empty spaces in silicon substrates is presented. The empty space with various shapes, such as plate as well as sphere and pipe, could be formed under the surface of the silicon substrate.
The corrosion of aluminium (1961)

Abstract The corrosion of aluminium at room temperature has been investigated in nine decinormal solutions over the pH range 2.0–12.0. Corrosion was dependent more on the nature of the anion than on the pH of the solution. The solubilities of hydrated and anhydrous aluminium oxide were examined and it was concluded that, except in the presence of chloride ions, corrosion was associated with the initial rate of solution of the anhydrous oxide. Potential and anodic polarisation measurements indicated that whereas the normal anodic reaction is the formation of anhydrous oxide, in the presence of chloride, bromide and iodide ions soluble aluminium salts are formed. It is suggested that when aluminium, carrying its air‐formed film, is immersed in a solution in the presence of oxygen, the film breaks down and a small corrosion current commences to flow. In the absence of chlorides, and similar ions, film repair can take place and the behaviour of the aluminium is controlled by the relative rates of film repair and film breakdown. In the presence of chlorides film repair does not occur and once corrosion has been initiated by film breakdown it proceeds apace. If initiation is suppressed, by saturating the solution with aluminium oxide, corrosion is inhibited.
Verifying configuration files (2010)

Configuration files are commonly used to create applications by gluing together new or existing components. However, components may be missing, misconfigured, or connected improperly, resulting in exceptions and unusual runtime behavior. This research contributes a mechanism to statically verify configuration files alongside the component code.
Probabilistic 3D Polyp Detection in CT Images: The Role of Sample Alignment (2006)

Automatic polyp detection is an increasingly important task in medical imaging with virtual colonoscopy [15] being widely used. In this paper, we present a 3D object detection algorithm and show its application on polyp detection from CT images. We make the following contributions: (1) The system adopts Probabilistic Boosting Tree (PBT) to probabilistically detect polyps. Integral volume and 3D Haar filters are introduced to achieve fast feature computation. (2) We give an explicit convergence rate analysis for the AdaBoost algorithm [2] and prove that the error at each step \in t+1. is tightly bounded by the previous error \in t. (3) For a 3D polyp template, a generative model is defined. Given the bound and convergence analysis, we analyze the role of "sample alignment" in the template design and devise a robust and efficient algorithm for polyp detection. The overall system has been tested on 150 volumes and the results obtained are very encouraging.
Efficacy of chloroquine and hydroxychloroquine in the treatment of COVID-19. (2020)

Chloroquine and hydroxychloroquine have antiviral characteristics in vitro. The findings support the hypothesis that these drugs have efficacy in the treatment of COVID-19. People are currently using these drugs for malaria. It is reasonable, given the hypothetical benefit of these two drugs, that they are now being tested in clinical trials to assess their effectiveness to combat this global health crisis.

Adaptive computing (2003)

The Adaptive Computing Systems (ACS) program was initiated by Defense Advanced Research Projects Agency (DARPA) of the United States in 1996. With the advent of FPGAs, has emerged a new class of computing systems that contain configurable hardware. This session begins by a presentation by the first ACS program manager of its motivation, original goals, and objectives. It is then followed by presentations of four specific projects under the ACS program. Future activities surrounding the ACS community will be discussed at the end.
Bit-serial bidirectional A/D/A conversion (2002)

A fault-tolerant VLSI architecture implementing a bi-directional bit-serial A/D/A (analog-to-digital and digital-to-analog) converter is presented. Both functions of algorithmic D/A conversion and successive approximation A/D conversion are combined into a single device, converting bits in the order from most to least significant. The MSB-first order allows for robust implementation, relatively insensitive to component mismatches, offsets and nonlinearities. Also, since the A/D conversion makes use of the intermediate D/A conversion results, matched monotonic characteristics are obtained in both directions of conversion. The final D/A result is available at the end of A/D conversion, and can be used directly in applications calling for analog quantization. More general use of the A/D/A converter allows for bi-directional read/write digital access to local analog information in VLSI. The cell supports dense integration of low-power data conversion units along with digital processors or sensory circuitry in a standard CMOS process. Experimental results from a prototype VLSI implementation are included. Including control logic, the A/D/A cell measures 216 /spl mu/m/spl times/315 /spl mu/m in a 2 /spl mu/m CMOS process, and achieves 8-bit untrimmed monotonicity at 200 /spl mu/W power consumption for a 20 /spl mu/sec conversion cycle.

A Magnetohydrodynamic Angular Motion Sensor for Anthropomorphic Test Device Instrumentation (1989)

&lt;div class="htmlview paragraph"&gt;Applied Technology Associates, Inc., (ATA) has developed a new angular motion sensor based on the laws of magnetohydrodynamics for the Department of Transportation. The magnetohydrodynamic angular motion sensor (MHD AMS) was originally developed for the Air Force for measurement of ultralow angular motion on pointing and tracking platforms. The transducer developed for the Department of Transportation, MHD AMS model IETL-001, or simply IETL, is a smaller, lighter version of the original MHD sensor with modifications which allow measurement of the high angular velocities incurred by the Anthropomorphic Test Device (ATD) heads in crash testing. The IETL weighs approximately 35 grams (1.2 02.) and occupies a volume of about 5 cubic centimeters (0.3 cubic inch). ATD application test results verify that the IETL exhibits both low cross-axis angular sensitivity and low linear acceleration sensitivity. These are important features for angular motion measurement in high shock environments, i.e., crash testing.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;The principle of operation, the physical and performance characteristics, and the ATD head application test results will be presented. In addition, a brief discussion of other related applications and design improvements will be given.&lt;/div&gt;
<title>Improved algorithmic mapping of color to texture</title> (2000)

Several improved algorithms to map color information to color or black texture are introduced. The new algorithms are based on pattern mixing and halftoning. The detailed algorithms are described along with the comparative analysis of their implementation. The analysis and the experiment result show that the halftone based algorithms described in this paper have advantages over the pattern mixing algorithm.
Elective Total Hip Arthroplasty in Patients Older Than 80 Years of Age (1991)

Elective total hip arthroplasties (THA) were performed in 91 patients (101 hips) older than 80 years of age at operation. A control group of 87 patients (102 hips) aged 64 to 67 years who had elective THA was chosen statistically to represent the average THA patient. There were 51 minor and eight major perioperative complications in the elderly group and 26 minor and two major complications in the control group. The only in-hospital death was in the control group. The mean hospital stay was two days longer in the elderly group. Five years postoperatively, 83% of the patients in both groups were ambulating without pain. The mean hip score improved from 49 to 84 points in the elderly group and from 52 to 88 points in the control group. These functional results justify elective THA in patients older than 80 years of age.
A Direct Route Towards Polymer/Copper Indium Sulfide Nanocomposite Solar Cells (2011)

New and Practical Method for Synthesis of 1- and 1,3-Substituted Xanthines (2004)

[reaction: see text] A new and practical method for the synthesis of 1- and 1,3-substituted xanthines is reported. Direct base-promoted condensation of the imidazole precursor 1 with carbamates 2 gives 1-substituted 7-PMB xanthines 7 in good yields. Alkylation of these derivatives or their potassium salts proceeds under mild conditions to give functionalized 1,3-substituted 7-PMB xanthines 9 in good to excellent yields. The obtained 7-PMB-protected derivatives can be readily deprotected to give the parent 1- and 1,3-substituted xanthines.
Multiparameter Flow Cytometric Analysis of Antibiotic Effects on Membrane Potential, Membrane Permeability, and Bacterial Counts of Staphylococcus aureus and Micrococcus luteus (2000)

Although flow cytometry has been used to study antibiotic effects on bacterial membrane potential (MP) and membrane permeability, flow cytometric results are not always well correlated to changes in bacterial counts. Using new, precise techniques, we simultaneously measured MP, membrane permeability, and particle counts of antibiotic-treated and untreated Staphylococcus aureus and Micrococcus luteus cells. MP was calculated from the ratio of red and green fluorescence of diethyloxacarbocyanine [DiOC(2)(3)]. A normalized permeability parameter was calculated from the ratio of far red fluorescence of the nucleic acid dye TO-PRO-3 and green DiOC(2)(3) fluorescence. Bacterial counts were calculated by the addition of polystyrene beads to the sample at a known concentration. Amoxicillin increased permeability within 45 min. At concentrations of <1 microg/ml, some organisms showed increased permeability but normal MP; this population disappeared after 4 h, while bacterial counts increased. At amoxicillin concentrations above 1 microg/ml, MP decreased irreversibly and the particle counts did not increase. Tetracycline and erythromycin caused smaller, dose- and time-dependent decreases in MP. Tetracycline concentrations of <1 microg/ml did not change permeability, while a tetracycline concentration of 4 microg/ml permeabilized 50% of the bacteria; 4 microg of erythromycin per ml permeabilized 20% of the bacteria. Streptomycin decreased MP substantially, with no effect on permeability; chloramphenicol did not change either permeability or MP. Erythromycin pretreatment of bacteria prevented streptomycin and amoxicillin effects. Flow cytometry provides a sensitive means of monitoring the dynamic cellular events that occur in bacteria exposed to antibacterial agents; however, it is probably simplistic to expect that changes in a single cellular parameter will suffice to determine the sensitivities of all species to all drugs.

Subpyriporphyrin—A [14]Triphyrin(1.1.1) Homologue with an Embedded Pyridine Moiety (2006)

Short and to the point: A three-centered hydrogen bond is present in 6,16-dimesityl-11-phenylsubpyriporphyrin, a non-aromatic free-base triphyrin(1.1.1)-related molecule. X-ray crystal structural analysis shows this compound contains the shortest known N⋅⋅⋅N distance (2.370 Å) for two N atoms involved in hydrogen bonding. The molecule also acts as a ligand, as shown by the formation of a boron complex.
Bringing multimedia contents into MP3 files (2005)

The digital music revolution has improved the availability of music and made it easier to enjoy. The shift from hard support, such as audio CDs, to software leaves some unsatisfied by the loss of additional media contents, such as images, lyrics, and CD cover. We propose to fill the gap by enriching e-music with multimedia contents. Our proposal focuses specifically on MP3 as a widely distributed open format. The challenge we meet in enriching MP3 lies in maintaining audio compatibility and avoiding file size explosion. To this end, we define a description language to express multimedia contents in a textual way, with higher representation efficiency than existing languages. We also address security issues that arise from the use of an open format. Effectiveness is shown with an MP3 player capable of rendering multimedia contents.
Mixed matrix membranes with fast and selective transport pathways for efficient CO2 separation (2018)

To improve CO<sub>2</sub> separation performance, porous carbon nanosheets (PCNs) were used as a filler into a Pebax MH 1657 (Pebax) matrix, fabricating mixed matrix membranes (MMMs). The PCNs exhibited a preferential horizontal orientation within the Pebax matrix because of the extremely large 2D plane and nanoscale thickness of the matrix. Therefore, the micropores of the PCNs provided fast CO<sub>2</sub> transport pathways, which led to increased CO<sub>2</sub> permeability. The reduced pore size of the PCNs was a consequence of the overlapping of PCNs and the polymer chains penetrating into the pores of the PCNs. The reduction in the pore size of the PCNs improved the CO<sub>2</sub>/gas selectivity. As a result, the CO<sub>2</sub> permeability and CO<sub>2</sub>/CH<sub>4</sub> selectivity of the Pebax membrane with 10 wt% PCNs-loading (Pebax-PCNs-10) were 520 barrer and 51, respectively, for CO<sub>2</sub>/CH<sub>4</sub> mixed-gas. The CO<sub>2</sub> permeability and CO<sub>2</sub>/N<sub>2</sub> selectivity of the Pebax-PCNs-10 membrane were 614 barrer and 61, respectively, for CO<sub>2</sub>/N<sub>2</sub> mixed-gas.

Generalized Nyquist Stability Criterion for Linear Time Periodic Systems (1990)

A generalized Nyquist stability criterion for linear time periodic systems is presented. This stability criterion is similar in many respects to the generalized Nyquist stability criterion for linear time invariant multi-input multi-output systems. The criterion is graphical and is based on the eigenloci of the transfer function operator that describes the input/output behavior of the system. The criterion has the advantage that it can determine the stability of a feedback system for a range of gains, whereas Floquet theory determines stability for only a specific gain.
Ex Situ Solvent‐Assisted Preparation of Magnetic Poly(propylene) 8nocomposites Filled with Fe@FeO Nanoparticles (2011)

Abstract Isotactic PP nanocomposites filled with Fe@FeO nanoparticles are fabricated by a facile ex situ method. The nanofillers are dispersed in a boiling PP/xylene solution. X‐ray diffraction is used to determine the nanofiller effects on the crystallinity of PP. The crystallinity along the (040) plane is found to decrease with the incorporation of nanoparticles. Thermal properties and crystallinity are studied by TGA and DSC, respectively. Enhanced thermal stability and influenced crystallinity are observed in the PP nanocomposites compared with those of pure PP. An increased dielectric property without percolation threshold is observed. In addition, the nanocomposites are found to exhibit ferromagnetic properties. magnified image
New packaging technology of highly stable “On-Chip” mode quantum dots LED (2017)

An highly efficient and stable OC-QLED (“On-Chip” mode quantum dots light-emitting diode, OC-QLED) was obtained by the new LED packaging method with quantum dots encapsulation, Which was well-suitable for the backlight module whose color gamut value > NTSC 103%. Firstly, the results of orthogonal designed experiment showed that the encapsulation method of quantum dots was the most significantly factor on reliability and luminous efficiency of OC-QLED in the 4 factors (quantum dots coating method, encapsulation compound, curing temperature and heating time). Then, the reliability and luminous efficiency of sandwich structure OC-QLED encapsulation (the sandwich structure meant encapsulate compound with clear silicone, red QD and green QD was placed on the blue LED chip layerly) were better than those of other structures. The luminous efficiency of sandwich structure OC-QLED was reported to 81% of that of the LED with YAG: Ce phosphor under the same packaging setting. The OC-QLED brightness slightly decayed 9.5% under 85 °C and 85 % humidity after 500 hour burning test and 5000 mW/cm2 optical power density of the package, respectively.
