Deformation mechanisms in PBT at elevated temperatures (2023)

The plastic deformation of Polybutylene terephthalate (PBT) is investigated at three temperatures (120$^\circ$C, 150$^\circ$C, 180$^\circ$C) representative of the span between glass transition, $T_g \approx 55^\circ$C and melting $T_m \approx 225^\circ$C temperatures. The mechanisms of tensile deformation are analyzed as a function of the true strain using a combination of temperature-controlled tensile experiments coupled with 2D digital image correlation and synchrotron sourced wide angle (WAXS) and small angle (SAXS) X-ray scattering the amorphous and crystalline regions causing the transition between polymorphs, respectively from the isotropic amorphous phase to a smectic phase and from the $α$ crystalline phase to the $β$ phase.
Visualization and quality control tools for large-scale multiplex tissue analysis in TissUUmaps3 (2023)

Large-scale multiplex tissue analysis aims to understand processes such as development and tumor formation by studying the occurrence and interaction of cells in local environments in, for example, tissue samples from patient cohorts. A typical procedure in the analysis is to delineate individual cells, classify them into cell types, and analyze their spatial relationships. All steps come with a number of challenges, and to address them and identify the bottlenecks of the analysis, it is necessary to include quality control tools in the analysis workflow. This makes it possible to optimize the steps and adjust settings in order to get better and more precise results. Additionally, the development of automated approaches for tissue analysis requires visual verification to reduce skepticism with regard to the accuracy of the results. Quality control tools could be used to build users' trust in automated approaches. In this paper, we present three plugins for visualization and quality control in large-scale multiplex tissue analysis of microscopy images. The first plugin focuses on the quality of cell staining, the second one was made for interactive evaluation and comparison of different cell classification results, and the third one serves for reviewing interactions of different cell types.

Design and Validation of a CT- and MRI-Guided Robot for Percutaneous Needle Procedures (2016)

This paper describes the design and evaluation of the second generation of a robotic system called the light puncture robot for thoracic and abdominopelvic interventional radiology procedures under CT and MRI guidance. It is mounted on the patient's body and positions and inserts the needle according to the trajectory and target chosen by the radiologist in the image. The mechanical design is described in detail along with its forward and inverse kinematics. The robot can be segmented and registered fully automatically in both imaging modalities. Phantom experiments in the CT scanner and preliminary feasibility experiments in the MRI are described, showing a targeting accuracy of 3.3 ± 1.7 mm in gelatin for depths ranging from 30 to 90 mm and needle orientations of -13° to +15° about normal from the patient's skin. A detailed error analysis is discussed along with potential improvements in the system. The potential clinical advantages of the system include higher targeting accuracy for complex dual obliquity trajectories, the need for fewer images, and improved accessibility to MRI-guided interventions.
Stochastic Resonance Effects of Floating Gate Technology-based Leaky Integrate-and-Fire (FG LIF) Neurons in Summing Network (2023)

The stochastic resonance effects are successfully simulated for the floating gate technology-based leaky integrate-and-fire (FG LIF) neurons in a summing network. Thanks to the stochastic electron injection effects of FG LIF neurons, the network can detect very short and weak input pulses. With the aggressively scaled FG LIF neurons from 100nm to 10nm, the representation error is reduced from 28% to 0.3% owing to the increased stochasticity of electron injections. In addition, the impacts of the leaky characteristics of FG LIF neurons on the representation error rate are discovered and discussed.
Mercury BLASTP (2008)

Large-scale protein sequence comparison is an important but compute-intensive task in molecular biology. BLASTP is the most popular tool for comparative analysis of protein sequences. In recent years, an exponential increase in the size of protein sequence databases has required either exponentially more running time or a cluster of machines to keep pace. To address this problem, we have designed and built a high-performance FPGA-accelerated version of BLASTP, Mercury BLASTP. In this paper, we describe the architecture of the portions of the application that are accelerated in the FPGA, and we also describe the integration of these FPGA-accelerated portions with the existing BLASTP software. We have implemented Mercury BLASTP on a commodity workstation with two Xilinx Virtex-II 6000 FPGAs. We show that the new design runs 11-15 times faster than software BLASTP on a modern CPU while delivering close to 99% identical results.

Kinetics of the Extraction of Succinic Acid with Tri‐n‐octylamine in 1‐Octanol Solution (2005)

Kinetic studies for the extraction of succinic acid from aqueous solution with 1-octanol solutions of tri-n-octylamine (TOA) were carried out using a stirred cell with a microporous hydrophobic membrane. The interfacial concentrations of species were correlated and thus the intrinsic kinetics was obtained. The overall extraction process was controlled by the chemical reaction at or near the interface between the aqueous and organic phases. The formation reaction of succinic acid-TOA complex was found to be first order with respect to the concentration of succinic acid in the aqueous phase and the order of 0.5 with respect to that of TOA in the organic phase with a rate constant of (3.14 +/- 0.6) x 10(-8) m(2.5) x mol(-0.5) x s(-1). The dissociation reaction of succinic acid-TOA complex was found to be the second-order with respect to that of succinic acid-TOA complex in the organic phase and the order of -2 with respect to that of TOA in the organic phase with a rate constant of (1.44 +/- 1.4) x 10(-4) mol x m(-2) x s(-1).

Sodium‐Doped Titania Self‐Rectifying Memristors for Crossbar Array Neuromorphic Architectures (2021)

Memristors integrated into a crossbar-array architecture (CAA) are promising candidates for nonvolatile memory elements in artificial neural networks. However, the relatively low reliability of memristors coupled with crosstalk and sneak currents in CAAs have limited the realization of the full potential of this technology. Here, high-reliability Na-doped TiO<sub>2</sub> memristors grown in situ by atomic layer deposition (ALD) are demonstrated, where reversible Na migration underlies the resistive-switching mechanism. By employing ALD growth with an aqueous NaOH reactant in deionized water, uniform implantation of Na dopants is achieved in the crystallized TiO<sub>2</sub> thin films at 250 °C without post-annealing. The resulting Na-doped TiO<sub>2</sub> memristors show electroforming-free and self-rectifying resistive-switching behavior, and they are ideally suited for selectorless CAAs. Effective addressing of selectorless nodes is demonstrated via electrical measurement of individual memristors in a 6 × 6 crossbar using a read current of less than 1 µA with negligible sneak current at or below the noise level of ≈100 pA. Finally, the long-term potentiation and depression synaptic behavior from these Na-doped TiO<sub>2</sub> memristors achieves greater than 99.1% accuracy for image-recognition tasks using a convolutional neural network based on the selectorless of crossbar arrays.
Population genetics of the coral Acropora millepora : Toward genomic prediction of bleaching (2020)

Although reef-building corals are declining worldwide, responses to bleaching vary within and across species and are partly heritable. Toward predicting bleaching response from genomic data, we generated a chromosome-scale genome assembly for the coral <i>Acropora millepora</i> We obtained whole-genome sequences for 237 phenotyped samples collected at 12 reefs along the Great Barrier Reef, among which we inferred little population structure. Scanning the genome for evidence of local adaptation, we detected signatures of long-term balancing selection in the heat-shock co-chaperone <i>sacsin</i> We conducted a genome-wide association study of visual bleaching score for 213 samples, incorporating the polygenic score derived from it into a predictive model for bleaching in the wild. These results set the stage for genomics-based approaches in conservation strategies.
Fresh BrowseRank (2013)

In the last years, a lot of attention was attracted by the problem of page authority computation based on user browsing behavior. However, the proposed methods have a number of limitations. In particular, they run on a single snapshot of a user browsing graph ignoring substantially dynamic nature of user browsing activity, which makes such methods recency unaware. This paper proposes a new method for computing page importance, referred to as Fresh BrowseRank. The score of a page by our algorithm equals to the weight in a stationary distribution of a flexible random walk, which is controlled by recency-sensitive weights of vertices and edges. Our method generalizes some previous approaches, provides better capability for capturing the dynamics of the Web and users behavior, and overcomes essential limitations of BrowseRank. The experimental results demonstrate that our method enables to achieve more relevant and fresh ranking results than the classic BrowseRank.
Proximity report triggering threshold optimization for network-based indoor positioning (2015)

Driven by the promising beaconing techniques, this paper presents a general received-signal-strength (RSS) threshold optimization procedure for proximity reports to support networkbased indoor positioning. The desired RSS threshold is found through optimizing a metric function (for instance the localization root-mean-square-error) in terms of both the deployment information and the RSS modeling in consideration of an evaluation area. The resulting RSS threshold provides a trade-off between triggering many but less informative proximity reports with a low threshold, and triggering few but very informative proximity reports with a high threshold, and thus enables enhanced performance for some low-cost and low-complex proximity based positioning algorithms. The proposed framework is also validated with real RSS measurements collected in an office area with deployed bluetooth low-energy (BLE) beacons.
Dependence of Glow Discharge Morphology on Diluent Gas and SiC14 Partial Pressure Si:H:C1 Film (1988)

TEM, THEED and field-assisted silver ion exchange have been employed to study the glow discharge (GD) Si:H:C1 films deposited from SiH4-SiC14 gas mixtures. The character of th'e THEED patterns shows that the films are rather amorphous, and that their structure does not alter with the change in the gas mixture. The honeycomb-like morphology of the films is strongly affected by the type of gas in which Sill4 is diluted (Ar or H2). An increase in the SiCI 4 partial pressure leads to the uniformity and to the decrease of the island dimension only for the films deposited from SiH4(H2)-SiC14. A possible correlation between the film morphology and the micropore density is proposed.
Fault-tolerance and reliability of post-CMOS systems: a circuit perspective (2009)

The reliability of systems made of unreliable nanoelectronic devices is discussed in this paper. Massive defect density which may affect future fabrication technologies calls for novel solutions, where spatial redundancy and the voting scheme play a significant role. The averaging and thresholding voting mechanism that was used in CMOS technologies is presented in the context of nanodevices, based on SET circuits. Theoretical developments supported by numerical simulations show that the presented voter and circuit architecture are also applicable in nanoelectronic design, and are superior to classical voters.
City of Rochester, NY Conduit Planning Study: Rush Reservoir to City Reservoirs (2008)

The City of Rochester, New York initiated a multi-phased water supply conduit modernization program for 28 miles of its Upland Supply system. The engineering planning for the project provided a comprehensive evaluation and a prioritized, fiscally sound, and multi-phased modernization plan. The project included comprehensive evaluation of leak records, leak record compilation and analysis, conduit evaluation, conduit rehabilitation and replacement alternatives; environmental, transportation, permitting and approval review, precise boundary, planimetric and topographic survey, mapping, corrosion evaluation, and hydraulic evaluation. The resulting conduit modernization plan is an economic and risk based program that includes an adaptive management strategy whereby conduit modernization priority can be updated based on recent break data.
Modeling of fractionation in CRYSTAF using Monte Carlo simulation of crystallizable sequence lengths: Ethylene/1‐octene copolymers synthesized with single‐site–type catalysts (2001)

Abstract Monte Carlo simulation was used to model the fractionation process in crystallization analysis fractionation (CRYSTAF). Five poly(ethylene/1‐octene) samples synthesized with a single‐site–type catalyst were used to verify the simulation results. It was proposed that the fractionation mechanism be controlled by the crystallization of the longest ethylene sequence in each chain. Good agreement between experimental and simulation results verified the validity of the proposed fractionation mechanism. © 2001 John Wiley &amp; Sons, Inc. J Appl Polym Sci 80: 2200–2206, 2001
Exploring potential applications of optical lattice clocks in a plate subduction zone (2021)

Abstract Optical clocks improved the accuracy of state-of-the-art cesium clocks by more than two orders of magnitude and enabled frequency comparison with a fractional uncertainty of one part in 10 18 . Gravitational redshift of two such clocks allows determining their height difference with an uncertainty of 1 cm. In Europe, chronometric leveling has been extensively conducted for unifying the height reference systems. Temporal response of the leveling, which affords monitoring a cm height variation within hours of averaging time, may offer new opportunities to explore seismology and volcanology. Superb stability of optical lattice clocks will be best used for such applications. This article outlines the prospects of chronometric leveling in Japan. Combining optical lattice clocks with an existing observation network of GNSS, crustal deformations may be monitored with unprecedented accuracy in the future.
221 On-Orbit System Identification Experiments on Engineering Test Satellite-VIII (2001)

The Engineering Test Satellite VIII(ETS-VIII), which will be launched in 2003, has large flexible appendages such as deployable antennas and paddles. On the other hand, high attitude accuracy is required, but it is hard to determine its flexibility parameters correctly under 1G circumstances of ground test facilities. The on-orbit system identification of its dynamics is very beneficial for this case, because it enables the validation of flexibility parameters used in the design phase, and besides the controllers gain tuning. The experiment of this identification is planed now. In this paper, we explain the overview of this experiment system and summarize the results of preliminary case studies for the system identification of the ETS-VIII dynamics model. In the case studies, it is assumed to use 1) attitude and translational responses during longitude station keeping maneuver, 2) step responses in normal operation mode and 3) impulse response in normal operation mode. The identification is feasible if the impulse responses are available. The responses during station keeping maneuver are not efficient for this identification without changing the conditions (e.g. the firing pattern of station keeping thrusters).
Optimization of Electrofusion Parameters for Efficient Production of Murine Hybridomas (1988)

Several factors which affect the production of murine hybridomas by electrofusion using SP2/0 myelomas were examined. These factors included the ionic composition, specific resistance and osmotic strength of the fusion medium, proteolytic pretreatment of the cells, and field strength of the single, rectangular, 15 or 20 microseconds electric pulse. Individual experiments were observed by phase microscopy, video-recorded, and subsequently analyzed. The efficiency of hybridoma formation was measured by the number of hybrid colonies which survived HAT medium selection. In most cases, the peak efficiency occurred when the pulse field was between 3 and 4 kV/cm. Ca++ and Mg++, in 0.1 and 0.5 mM concentrations, respectively, helped to prevent large-scale SP2/0 lysis following pulse application. Reduction of the osmolarity of the fusion medium allowed for an approximate two-fold increase in the hybrid production efficiency. However, other variations, including an increase of the specific resistance of the medium to 1.7 x 10(4) omega cm, and a reduction of the pulse width to 15 microseconds, allowed significantly higher efficiencies. Dispase pretreatment of the myelomas led to additional improvements when using a 15 microseconds pulse. The data suggest that for this system, the highest efficiencies are obtained by maximizing the attractive polarization forces between cells, while adjusting the ionic composition and pulse parameters to preserve myeloma viability.

Simulation of charge cloud evolution in silicon drift detectors (2002)

The spread of the signal during the drift period before collection is a critical parameter for silicon drift detector operation. In this work, simulations have been used to gain an understanding of the charge cloud evolution. Diffusion, Coulomb repulsion within the charge cloud, and variations in the drift field were all found to influence the signal spread. Fluctuations in dopant concentration were found to dramatically influence the drift field.

Introducing Purion H, a scanned spot beam high current ion implanter (2014)

As a member of the Purion ion implanter family, Purion H is Axcelis' next generation high current implanter. Purion H provides customers with an unprecedented level of process flexibility and yield-enabling technology, and features the platform's four common differentiators: Purion Contamination Shield™, Purion Vector™ Dose and Angle Control System, Purion 500 wafer/hour endstation and the Eterna™ ELS source. Like Purion M and Xe, Purion H uses a hybrid scan architecture. Its scanned spot beam technology delivers precise dosage, angle and dose rate on all points of the wafer, by permitting simultaneous and independent implant uniformity and angle control. Purion H high also comprises a five-filter beamline to deliver beam purity for low variability and defects: a series of dipole magnets and a deflecting energy filter separate unwanted contaminants from the ion beam. Magnetic beam scanning permits space-charge neutralization of high beam currents, resulting in high productivity via high beam currents in combination with short tune times and a fast 500 wafer/hour end station. Other new features include a maintenance friendly, integrated source extraction system; a novel uniformity correction algorithm; a new, higher output microwave PEF powered by a solid-state amplifier for metals-free charge neutralization of high current beams; and advanced beam diagnostics to quantify average angles and spread of the scanned spot beam. Finally, the dosimetry system, which is common to the Purion M medium current implanter, extends the application space of Purion H beyond the traditional coverage of high current implanters down to doses <; 2e11 /cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , enabling new applications while maintaining productivity.
Distributed loading effect for infrared FSS (2007)

Frequency selective surfaces (FSS) are traditionally resonant periodic antenna structures patterned on a surface for the purpose of spectral filtering. At infrared (IR) frequencies, FSS structures have been successfully demonstrated as both transmission filters and surface emissivity modifiers. In this paper, distributed loading effect for infrared FSS was investigated using four pure metals as distributed load: aluminum, gold, nickel, and titanium.
Application of Alcohol Dehydrogenase Allozymes in Testing the Genetic Purity of F1 Hybrids of Tomato1 (1981)

Abstract Seed extracts of a number of fresh market cultivars of tomato ( Lycopersicon esculen-tum Mill.) were subjected to starch gel electrophoresis and stained for alcohol dehydrogenase activity to investigate the possibility of utilizing allozymic variation to determine genetic purity of F 1 hybrids. Of the varieties tested 46% proved amenable to the test. This method offers a practical and rapid means of estimating seed contamination frequencies in commercial seed lots as well as distinguishing hybrids from parental lines in the field.
