Blue Gene/L, a system-on-a-chip (2003)

Summary form only given. Large powerful networks coupled to state-of-the-art processors have traditionally dominated supercomputing. As technology advances, this approach is likely to be challenged by a more cost-effective System-On-A-Chip approach, with higher levels of system integration. The scalability of applications to architectures with tens to hundreds of thousands of processors is critical to the success of this approach. Significant progress has been made in mapping numerous compute-intensive applications, many of them grand challenges, to parallel architectures. Applications hoping to efficiently execute on future supercomputers of any architecture must be coded in a manner consistent with an enormous degree of parallelism. The BG/L program is developing a peak nominal 180 TFLOPS (360 TFLOPS for some applications) supercomputer to serve a broad range of science applications. BG/L generalizes QCDOC, the first System-On-A-Chip supercomputer that is expected in 2003. BG/L consists of 65,536 nodes, and contains five integrated networks: a 3D torus, a combining tree, a Gb Ethernet network, barrier/global interrupt network and JTAG.

Hydrophilic Diesel Fuels - Ignition Delay Times of Several Different Blends (1997)

&lt;div class="htmlview paragraph"&gt;Alternative fuels based on biomass have typically been specified in ways which substantially limit allowable compositions. These specifications are unlike those for petroleum based fuels which include mixtures comprised of hundreds of different compounds. Such narrow biofuel specifications are clearly disadvantageous by restricting any flexibility of using different biofuels to minimize costs and offset price fluctuations. This paper focuses on critical performance criteria for diesel fuels and provides experimental data on several, non-conventional biofuels. Experimental data includes the physical properties and ignition delay times of new, lower cost sugar formulations.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;The objective of this work is to develop specifications on volumetric heating value, viscosity, and ignition properties as well as other properties for compression ignition biofuels. Proposed fuel specifications would not include compositions, thereby allowing a variety of feedstocks to be used. Potential feedstocks include pyrolysis oils, methanol, ethanol, and sugars.&lt;/div&gt;
The structure and DNA-binding properties of Mgm101 from a yeast with a linear mitochondrial genome (2016)

To study the mechanisms involved in the maintenance of a linear mitochondrial genome we investigated the biochemical properties of the recombination protein Mgm101 from Candida parapsilosis. We show that CpMgm101 complements defects associated with the Saccharomyces cerevisiae mgm101-1(ts) mutation and that it is present in both the nucleus and mitochondrial nucleoids of C. parapsilosis. Unlike its S. cerevisiae counterpart, CpMgm101 is associated with the entire nucleoid population and is able to bind to a broad range of DNA substrates in a non-sequence specific manner. CpMgm101 is also able to catalyze strand annealing and D-loop formation. CpMgm101 forms a roughly C-shaped trimer in solution according to SAXS. Electron microscopy of a complex of CpMgm101 with a model mitochondrial telomere revealed homogeneous, ring-shaped structures at the telomeric single-stranded overhangs. The DNA-binding properties of CpMgm101, together with its DNA recombination properties, suggest that it can play a number of possible roles in the replication of the mitochondrial genome and the maintenance of its telomeres.
SDR-Based Resilient Wireless Communications (2017)

As the use of wireless technologies increases significantly due to ease of deployment, cost-effectiveness and the increase in bandwidth, there is a critical need to make the wireless communications secure, and resilient to attacks or faults (malicious or natural). Wireless communications are inherently prone to cyberattacks due to the open access to the medium. While current wireless protocols have addressed the privacy issues, they have failed to provide effective solutions against denial of service attacks, session hijacking and jamming attacks. In this paper, we present a resilient wireless communication architecture based on Moving Target Defense, and Software Defined Radios (SDRs). The approach achieves its resilient operations by randomly changing the runtime characteristics of the wireless communications channels between different wireless nodes to make it extremely difficult to succeed in launching attacks. The runtime characteristics that can be changed include packet size, network address, modulation type, and the operating frequency of the channel. In addition, the lifespan for each configuration will be random. To reduce the overhead in switching between two consecutive configurations, we use two radio channels that are selected at random from a finite set of potential channels, one will be designated as an active channel while the second acts as a standby channel. This will harden the wireless communications attacks because the attackers have no clue on what channels are currently being used to exploit existing vulnerability and launch an attack. The experimental results and evaluation show that our approach can tolerate a wide range of attacks (Jamming, DOS and session attacks) against wireless networks.

Construction of Three‐Dimensional DNA Hydrogels from Linear Building Blocks (2014)

Abstract A three‐dimensional DNA hydrogel was generated by self‐assembly of short linear double‐stranded DNA (dsDNA) building blocks equipped with sticky ends. The resulting DNA hydrogel is thermoresponsive and the length of the supramolecular dsDNA structures varies with temperature. The average diffusion coefficients of the supramolecular dsDNA structures formed by self‐assembly were determined by diffusion‐ordered NMR spectroscopy (DOSY NMR) for temperatures higher than 60 °C. Temperature‐dependent rheological measurements revealed a gel point of 42±1 °C. Below this temperature, the resulting material behaved as a true gel of high viscosity with values for the storage modulus G ′ being significantly larger than that for the loss modulus G ′′. Frequency‐dependent rheological measurements at 20 °C revealed a mesh size ( ξ ) of 15 nm. AFM analysis of the diluted hydrogel in the dry state showed densely packed structures of entangled chains, which are also expected to contain multiple interlocked rings and catenanes.

An active clamp circuit for voltage regulation module (VRM) applications (2001)

This paper discusses the design, fabrication, and testing of a CMOS active clamp circuit, The active clamp is a linear voltage regulator, with a voltage deadband to allow for voltage ripple, that is designed to operate in parallel with a switchmode voltage regulator. Its specific function is to sink or source large transient currents to microprocessor loads, thus allowing operation with very small output capacitance. Laboratory tests on a prototype IC exhibit stable behavior with negligible overshoot with only 47 microfarads of output capacitance with loads of about nine amperes. Output impedances of 2-3 m/spl Omega/ are achieved.
Oscillator performance and energy extraction from a KrF laser pumped by a high-intensity relativistic electron beam (1980)

The resulting optimum conditions gave an intrinsic efficiency (laser energy out/electron-beam energy deposited) of 12 percent for the 1000 torr total pressure mixture with an output energy of 11 J/1. An efficiency of 10 percent with an output of 40 J/1 was obtained for the 2500 torr mixture. The system was then used as an amplifier to measure the extracted power as a function of input power for the two mixtures.

Machine Learning Approach for Biopsy-Based Identification of Eosinophilic Esophagitis Reveals Importance of Global features (2021)

Goal: Eosinophilic esophagitis (EoE) is an allergic inflammatory condition characterized by eosinophil accumulation in the esophageal mucosa. EoE diagnosis includes a manual assessment of eosinophil levels in mucosal biopsies–a time-consuming, laborious task that is difficult to standardize. One of the main challenges in automating this process, like many other biopsy-based diagnostics, is detecting features that are small relative to the size of the biopsy. Results: In this work, we utilized hematoxylin- and eosin-stained slides from esophageal biopsies from patients with active EoE and control subjects to develop a platform based on a deep convolutional neural network (DCNN) that can classify esophageal biopsies with an accuracy of 85%, sensitivity of 82.5%, and specificity of 87%. Moreover, by combining several downscaling and cropping strategies, we show that some of the features contributing to the correct classification are global rather than specific, local features. Conclusions: We report the ability of artificial intelligence to identify EoE using computer vision analysis of esophageal biopsy slides. Further, the DCNN features associated with EoE are based on not only local eosinophils but also global histologic changes. Our approach can be used for other conditions that rely on biopsy-based histologic diagnostics.
COMPARATIVE EVALUATION OF UROGRAPHIC CONTRAST MEDIA, INULIN, AND 99mTc-DTPA CLEARANCE METHODS FOR DETERMINATION OF GLOMERULAR FILTRATION RATE IN CLINICAL TRANSPLANTATION (1989)

Plasma clearance of inulin (Cin), 99mTc-DTPA (CDTPA), and urographic contrast media (CCM) were determined simultaneously in 31 patients with varying levels of renal function evaluated in the setting of affiliated cardiac and renal transplantation programs. Cin and CDTPA were calculated from the ratio of simultaneously measured plasma concentration and urine excretion rate of these test agents (UxV/P). CCM was derived from x-ray fluorescence measurement of plasma iodine (PI) content following intravenous injection of 50 ml of nonionic, low-osmolar contrast media (180 mg I/ml). Urine collections were not required for CCM determinations. No adverse reactions attributable to CM occurred in any patient, and follow-up serum-creatinine values did not differ significantly from prestudy levels. CCM determined from the rate of decline in PI between 3 hr and 4 hr following administration of contrast media ("slope-intercept" technique) [Ccm-SI] correlated closely with corresponding levels of Cin (r = .86, P less than 0.0001). and CDTPA (r = 0.89, P less than 0.0001). Mean CCM-SI/Cin and CCM-SI/CDTPA ratios for the entire study cohort were 1.09 +/- 0.06 and 1.08 +/- 0.06, respectively. CCM-SI determinations also correlated well with CCM levels derived from a single measurement of PI ("single sample" technique) made at 3 hr following injection of contrast media (r = 0.94, P less than 0.0001). Both CCM-SI and CCM determined by the "single sample" method (CCM-3 degrees SS) tended to overestimate Cin and CDTPA, however, when the latter were less than 20 ml/min/1.73 m2 (mean CCM-SI/Cin and Ccm-3 degrees SS/Cin ratios 1.36 +/- 0.14 and 1.95 +/- 1.0, respectively. Reproducibility was evaluated by paired comparison of 3-hr vs. 4-hr "single sample" CCM determinations (r = 0.99, P less than 0.0001). In addition, analysis of the variation in iodine content between duplicate specimens obtained at each of these time intervals revealed a mean ratio of 1.0 +/- 0.01 (P = NS vs. identity). Contrast clearance determination utilizing the slope-intercept method is accurate, safe, pragmatic, and more precise than serum-creatinine and endogenous-creatinine clearance for measurement of renal function in clinical transplantation.
Stress‐induced lncRNAs evade nuclear degradation and enter the translational machinery (2013)

Long noncoding RNAs (lncRNAs) play important roles in the regulation of gene expression. In fission yeast, glucose starvation triggers a transcriptional cascade of polyadenylated lncRNAs in the upstream region of the fructose-1,6-bisphosphatase gene (fbp1(+) ), which is correlated with stepwise chromatin remodeling and necessary for the massive induction of fbp1(+) mRNA. Here, we show that these novel metabolic stress-induced lncRNAs (mlonRNAs) are 5'-capped, less stable than fbp1(+) mRNA and sensitive to a certain extent to the nuclear exosome cofactor Rrp6. However, most mlonRNAs seem to escape nuclear degradation and are exported to the cytoplasm, where they localize to polysomes precisely during glucose starvation-induced global translation inhibition. It is likely that ribosomes tend to accumulate in the upstream region of mlonRNAs. Although mlonRNAs contain an unusual amount of upstream AUGs (uAUGs) and small open reading frames (uORFs), they escape Upf1-mediated targeting to the non-sense-mediated decay (NMD) pathway. The deletion of Upf1 had no effect on mlonRNA stability, but considerably destabilized fbp1(+) mRNA, hinting toward a possible novel role of Upf1. Our findings suggest that the stability of mlonRNAs is distinctly regulated from mRNA and previously described noncoding transcripts.
Responses to “A Movement Divided” by Samuel Escobar (1992)

Social Transformation was not the only perspective coming out of Lausanne 74; there was also the focus on closure on the task of evangelisation with an emphasis on unreached peoples. The function of those with this latter vocation must not be understood as a different trend as though they dismissed the importance of social transformation. There is simply a difference of function between planting churches and nurturing them. Escobar's (and others' in his third-world missiology category) role is as a scholar rather than a front line evangelist; his cultural perspective is still from a western perspective that moved south, and he did not work closely with McGavran. The grassroots task of bringing the Word to unreached peoples in non-Western cultures in many unmanaged ways is the bedrock base for the ministry of social transformation Escobar espouses.
Advanced alternate planar geometry solid oxide fuel cells; 18th interim technical progress report, October 1, 1989--December 31, 1989 (1989)

During this quarter work was carried out under Task 2, Test Facility Preparation, Task 6, Interconnect Development and Fabrication, Task 7, Out-of-Cell Testing, and Task 8, In-Cell Testing. Under Task 2, assembly of the solid oxide test stand was completed. Further modifications were made as testing progressed. Under Task 6, Yttrium Iron Garnet material was evaluated for use as interconnect. Under Task 7, seal tests were begun on candidate manifold seal materials. Under Task 8, two cell tests were performed on a single cell provided by Ceramatec. The first of these cell tests, referred to as CTK-1, served as a short, shake-down run for which no significant performance data was obtained. The second cell test, CTK-2, performed quite well. It appears that performance of this cell was similar to that obtained by Ceramatec on a small electrolyte disc (cell DOE-8 with bilayer electrolyte, infiltrated LSM cathode and Pt anode). Performance of the cell degraded within several days and the test was shut down before significant degradation occurred. A maximum OCV of 867 mV was obtained at 771{degree} C. The best performance under load was 275 mA/cm{sup 2} at 500 mV which was about 89% small cell tested at Ceramatec (DOE8).more » Electrode materials include: NiO/ZrO{sub 2}, La(Sr) MnO{sub 3}.« less
A Potentiodynamic Evaluation of NiMo and NiTi Amorphous Thin Films (1986)

Ion beam mixing has been used to fabricate amorphous metallic alloy coatings of NiMo and NiTi substrates. Alternate thin layers (~ 100 Å) of Mo and Ni and Ti and Ni with different thicknesses were prepared by e-beam evaporation. The thicknesses of individual films were adjusted to obtain an overall composition of N50Mo50, and Ni50Ti50, after mixing. Ions of 1 MeV Au+ and Pt+ and 350 keV Cr+ were used for mixing. The mixed layers were found to be amorphous and were tested for their corrosion behavior by potentiodynamic polarization techniques. Results have shown that amorphous NiTi forms a better coating than amorphous NiMo when surveyed in 1 N HNO3 and 0.1 N NaCl solutions. In general, amorphous coatings have demonstrated better corrosion resistance than their polycrystalline counterparts.
Terahertz-Field-Induced Nonlinear Electron Delocalization in Au Nanostructures (2015)

Improved control over the electromagnetic properties of metal nanostructures is indispensable for the development of next-generation integrated nanocircuits and plasmonic devices. The use of terahertz (THz)-field-induced nonlinearity is a promising approach to controlling local electromagnetic properties. Here, we demonstrate how intense THz electric fields can be used to modulate electron delocalization in percolated gold (Au) nanostructures on a picosecond time scale. We prepared both isolated and percolated Au nanostructures deposited on high resistivity Si(100) substrates. With increasing the applied THz electric fields, large opacity in the THz transmission spectra takes place in the percolated nanostructures; the maximum THz-field-induced transmittance difference, 50% more, is reached just above the percolation threshold thickness. Fitting the experimental data to a Drude-Smith model, we found furthermore that the localization parameter and the damping constant strongly depend on the applied THz-field strength. These results show that ultrafast nonlinear electron delocalization proceeds via strong electric field of THz pulses; the intense THz electric field modulates the backscattering rate of localized electrons and induces electron tunneling between Au nanostructures across the narrow insulating bridges without any material breakdown.

Communication power struggles on social media: A case study of the 2011–12 Russian protests (2017)

In 2011–2012 Russia experienced a wave of mass protests surrounding the Duma and presidential elections. The protests, however, faded shortly after the second election. We study the Russian political discourse on Twitter during this period and the main actors involved: the pro-government camp, the opposition, and the general public. We analyze around 700,000 Twitter messages and investigate the social networks of the most active Twitter users. Our analysis shows that pro-government users employed a variety of communication strategies to shift the political discourse and marginalize oppositional voices on Twitter. This demonstrates how authorities can disempower regime critics and successfully manipulate public opinion on social media.
