Exploiting dynamic quantum circuits in a quantum algorithm with superconducting qubits (2021)

The execution of quantum circuits on real systems has largely been limited to those which are simply time-ordered sequences of unitary operations followed by a projective measurement. As hardware platforms for quantum computing continue to mature in size and capability, it is imperative to enable quantum circuits beyond their conventional construction. Here we break into the realm of dynamic quantum circuits on a superconducting-based quantum system. Dynamic quantum circuits involve not only the evolution of the quantum state throughout the computation, but also periodic measurements of a subset of qubits mid-circuit and concurrent processing of the resulting classical information within timescales shorter than the execution times of the circuits. Using noisy quantum hardware, we explore one of the most fundamental quantum algorithms, quantum phase estimation, in its adaptive version, which exploits dynamic circuits, and compare the results to a non-adaptive implementation of the same algorithm. We demonstrate that the version of real-time quantum computing with dynamic circuits can offer a substantial and tangible advantage when noise and latency are sufficiently low in the system, opening the door to a new realm of available algorithms on real quantum systems.
Data from Aging of Preleukemic Thymocytes Drives CpG Island Hypermethylation in T-cell Acute Lymphoblastic Leukemia (2023)

&lt;div&gt;Abstract&lt;p&gt;Cancer cells display DNA hypermethylation at specific CpG islands in comparison with their normal healthy counterparts, but the mechanism that drives this so-called CpG island methylator phenotype (CIMP) remains poorly understood. Here, we show that CpG island methylation in human T-cell acute lymphoblastic leukemia (T-ALL) mainly occurs at promoters of Polycomb Repressor Complex 2 (&lt;i&gt;PRC2&lt;/i&gt;) target genes that are not expressed in normal or malignant T cells and that display a reciprocal association with H3K27me3 binding. In addition, we reveal that this aberrant methylation profile reflects the epigenetic history of T-ALL and is established already in preleukemic, self-renewing thymocytes that precede T-ALL development. Finally, we unexpectedly uncover that this age-related CpG island hypermethylation signature in T-ALL is completely resistant to the FDA-approved hypomethylating agent decitabine. Altogether, we provide conceptual evidence for the involvement of a preleukemic phase characterized by self-renewing thymocytes in the pathogenesis of human T-ALL.&lt;/p&gt;Significance:&lt;p&gt;We developed a DNA methylation signature that reveals the epigenetic history of thymocytes during T-cell transformation. This human signature was recapitulated by murine self-renewing preleukemic thymocytes that build an age-related CpG island hypermethylation phenotype, providing conceptual evidence for the involvement of a preleukemic thymic phase in human T-cell leukemia.&lt;/p&gt;&lt;p&gt;&lt;i&gt;This article is highlighted in the In This Issue feature, p. 215&lt;/i&gt;&lt;/p&gt;&lt;/div&gt;
Formation of Polyimide Nanoparticles in Heterophase with an Ionic Liquid as Continuous Phase (2009)

Polyimide nanoparticles were obtained by the heterophase polycondensation of different aromatic tetracarboxylic acids and diamines in imidazolium-based ionic liquids (IL) as continuous phase. Because of the amphiphilic character of the IL, no additional surfactant is required for the stabilization of the employed dispersions. The low vapor pressure and high thermal stability of the reaction medium allow the use of high temperatures needed for the condensation reaction. The reaction takes place without commonly added extra components like LiCl or pyridine. The obtained polyimide was characterized by IR spectroscopy and gel permeation chromatography (GPC). Electron microscopy (TEM and SEM) shows a homogeneous morphology of the nanoparticles.

Effect of Prior Oxidation on the Reduction Behavior of Magnetite-Based Iron Ore During Hydrogen-Induced Fluidized Bed Reduction (2021)

Abstract Magnetite-based iron ore usually shows a high sticking tendency and a poor reducibility in the fluidized bed because of its dense structure. To enhance the fluidization and reduction behaviors of magnetite-based iron ore during hydrogen-induced fluidized bed reduction, the effect of a prior oxidation treatment is investigated. The results show that the untreated magnetite-based iron ore cannot be fluidized successfully in the tested temperature range between 600 °C and 800 °C. At 600 °C reduction temperature, the de-fluidization can be avoided by a prior oxidation treatment. At higher reduction temperatures, the fluidization behavior can be further improved by an addition of 0.5 wt pct MgO. Magnesiowüstite (Fe x Mg 1− x O) is formed, which decreases the contact chance of the sticky surface between particles. Regarding to the reduction rate, a prior partial oxidation is more beneficial compared to deep oxidation. The kinetic analysis shows that MgO could promote the initial reaction. The reaction rate limiting step is no longer diffusion but chemical reaction for prior partly oxidized samples. A prior partial oxidation combined with an addition of MgO is considered to be a promising pretreatment method for a successful processing of magnetite-based iron ore.
Vibration suppressing control method of angular transmission error of cycloid gear for industrial robots (2014)

This paper proposes a method for suppressing the speed vibration caused by the angular transmission error in the cycloid gear used in industrial robots. It is important for industrial robots to have high accuracy. The arms of robot, however, are caused to vibrate by cycloid gears that have an angular transmission error. The proposed method for compensating for the speed vibration uses a new extended state observer that is based on the model of a cycloid gear with angular transmission error. A compensation current is produced from the torque vibration, which is converted by the estimated speed vibration. The speed vibration is suppressed using this compensation current. The experimental results show that the proposed system suppresses the vibration of load speed.
Composite Interlayer Consisting of Alcohol-Soluble Polyfluorene and Carbon Nanotubes for Efficient Polymer Solar Cells (2020)

We report the synthesis of composite interlayers using alcohol-soluble polyfluorene (ASP)-wrapped single-walled carbon nanotubes (SWNTs) and their application as electron-transport layers for efficient organic solar cells. The ASP enables the individual dispersion of SWNTs in solution. The ASP-wrapped SWNT solutions are stable for 54 days without any aggregation or precipitation, indicating their very high dispersion stability. Using the ASP-wrapped SWNTs as a cathode interlayer on zinc oxide nanoparticles (ZnO NPs), a power conversion efficiency of 9.45% is obtained in PTB7-th:PC<sub>71</sub>BM-based organic solar cells, which is mainly attributed to the improvement in the short circuit current. Performance enhancements of 18 and 17% are achieved compared to those of pure ZnO NPs and ASP on ZnO NPs, respectively. In addition, the composite interlayer is applied to non-fullerene-based photovoltaics with PM6:Y6, resulting in a power conversion efficiency of up to 14.37%. The type of SWNT (e.g., in terms of diameter range and length) is not critical to the improvement in the charge-transport properties. A low density of SWNTs in the film (∼1 SWNTs/μm<sup>2</sup> for ASP-wrapped SWNTs) has a significant influence on the charge transport in solar cells. The improvement in the performance of the solar cell is attributed to the increased internal quantum efficiency, balanced mobility between electrons and holes, and minimized charge recombination.
A Bearingless Synchronous Reluctance Slice Motor with Rotor Flux Barriers (2018)

This paper presents a bearingless synchronous reluctance slice motor, which contains no permanent magnets. The rotor with four iron poles and flux barriers is levitated and rotated through a stator winding system with six coils wired as two three-phase systems. After applying a constant rotor oriented magnetization current, the system can be controlled just like a bearingless permanent magnet synchronous slice motor, including the passive stabilization of axial and tilting movements. In a first step, the motor geometry is being optimized and the performance characteristics of the designed motor are examined. The motor is then compared to two other designs, which contain permanent magnets either in the rotor or the stator. The comparison includes torque generation, radial force generation, passive axial and tilting stiffnesses and wide air gap suitability. The introduced topology outperforms the others for ultra high process or ambient temperatures and rotor disposable applications with a short exchange interval.
On efficiently searching trajectories and archival data for historical similarities (2008)

We study the problem of efficiently evaluating similarity queries on histories, where a history is a d -dimensional time series for d ≥ 1. While there are some solutions for time-series and spatio-temporal trajectories where typically d ≤ 3, we are not aware of any work that examines the problem for larger values of d. In this paper, we address the problem in its general case and propose a class of summaries for histories with a few interesting properties. First, for commonly used distance functions such as the L p -norm, LCSS, and DTW, the summaries can be used to efficiently prune some of the histories that cannot be in the answer set of the queries. Second, histories can be indexed based on their summaries, hence the qualifying candidates can be efficiently retrieved. To further reduce the number of unnecessary distance computations for false positives, we propose a finer level approximation of histories, and an algorithm to find an approximation with the least maximum distance estimation error. Experimental results confirm that the combination of our feature extraction approaches and the indexability of our summaries can improve upon existing methods and scales up for larger values of d and database sizes, based on our experiments on real and synthetic datasets of 17-dimensional histories.

Admission and power control for cognitive radio networks by sequential geometric programming (2011)

In cognitive radio (CR) networks, power control is an effective means to limit the interference caused by the CRs upon the incumbent primary users (PUs) to ensure cohabitation of the two systems. When all CR links can not be active at the same time due to excessive interference, an admission control mechanism is necessary to schedule the CR links. Key to both tasks is accurate knowledge of the CR-to-PU channel gains. However, CRs generally face difficulties in estimating the channel gains very accurately, often due to lack of explicit support from the PU systems. In this work, admission and power control algorithms are developed to account for channel uncertainty through probabilistic interference constraints. Both log-normal shadowing and small-scale fading effects are considered through suitable approximations. The resulting problems can be solved via sequential geometric programming. The admission control is based on solving feasibility problems, whereby CR links violating the interference constraints the most are dropped progressively. The feasible point thus found to initialize the power control iterative solver.

Advanced gradient-index lens design tools to maximize system performance and reduce SWaP (2016)

GRadient-INdex (GRIN) lenses have long been of interest due to their potential for providing levels of performance unachievable with traditional homogeneous lenses. While historically limited by a lack of suitable materials, rapid advancements in manufacturing techniques, including 3D printing, have recently kindled a renewed interest in GRIN optics. Further increasing the desire for GRIN devices has been the advent of Transformation Optics (TO), which provides the mathematical framework for representing the behavior of electromagnetic radiation in a given geometry by “transforming” it to an alternative, usually more desirable, geometry through an appropriate mapping of the constituent material parameters. Using TO, aspherical lenses can be transformed to simpler spherical and flat geometries or even rotationally-asymmetric shapes which result in true 3D GRIN profiles. Meanwhile, there is a critical lack of suitable design tools which can effectively evaluate the optical wave propagation through 3D GRIN profiles produced by TO. Current modeling software packages for optical lens systems also lack advanced multi-objective global optimization capability which allows the user to explicitly view the trade-offs between all design objectives such as focus quality, FOV, &utri;<i>n</i>and focal drift due to chromatic aberrations. When coupled with advanced design methodologies such as TO, wavefront matching (WFM), and analytical achromatic GRIN theory, these tools provide a powerful framework for maximizing SWaP (Size, Weight and Power) reduction in GRIN-enabled optical systems. We provide an overview of our advanced GRIN design tools and examples which minimize the presence of mono- and polychromatic aberrations in the context of reducing SWaP.
A Specific Template‐Assembled Peptidic Agonist for the Angiotensin II Receptor Subtype 2 (AT2) and its Effect on Inferior Olivary Neurones (1995)

We synthesized a molecule composed of two angiotensin II 4-8 pentapeptide fragments attached to a carrier molecule (TA), according to the template-assembled synthetic proteins concept. This molecule was investigated for receptor binding on angiotensin type-1 and type-2 receptors (AT1 and AT2) and its biological activity was determined by iontophoretic experiments on neurones of the inferior olive (ION) that express only AT2 receptors. TA binds exclusively to the AT2 receptor and mediates an agonistic angiotensin-II effect on the ION. TA is the first agonist available to study the direct stimulation of AT2 receptors.
In vitro effects of histamine receptor 1 antagonists on proliferation and histamine release in canine neoplastic mast cells (2020)

Canine mastocytomas (MCTs) are characterized by rapid proliferation of neoplastic mast cells (MCs) and clinical signs caused by MC-derived mediators. In dogs suffering from MCT, histamine receptor 1 (HR1) antagonists are frequently used to control mediator-related clinical symptoms. Previous studies have shown that the HR1 antagonists loratadine and terfenadine exert some growth-inhibitory effects on neoplastic MCs. We examined whether other HR1 antagonists used in clinical practice (desloratadine, rupatadine, cyproheptadine, dimetindene, diphenhydramine) affect proliferation and survival of neoplastic MCs. Furthermore, we analysed whether these HR1 antagonists counteract IgE-dependent histamine release from a MC line harbouring a functional IgE-receptor. HR1 antagonists were applied on two canine MC lines, C2 and NI-1, and on primary MCs obtained from three MCT samples. The HR1 antagonists desloratadine, rupatadine and cyproheptadine were found to be more potent in decreasing proliferation of C2 and NI-1 cells when compared with dimetindene and diphenhydramine. Similar effects were seen in primary neoplastic MCs, except for diphenhydramine, which exerted more potent growth-inhibitory effects than the other HR1 antagonists. Drug-induced growth-inhibition in C2 and NI-1 cells was accompanied by apoptosis. Loratadine, desloratadine and rupatadine also suppressed IgE-dependent histamine release in NI-1 cells. However, drug concentrations required to elicit substantial effects on growth or histamine release were relatively high (>10 µM). Therefore, it remains unknown whether these drugs or similar, more potent, HR1-targeting drugs can suppress growth or activation of canine neoplastic MCs in vivo.
A 60 GHz-band low noise HJFET amplifier module for wireless LAN applications (2002)

A 60 GHz-band low noise amplifier (LNA) module has been developed based on 0.15 /spl mu/m AlGaAs/InGaAs heterojunction FET (HJFET) technologies. A two-stage MMIC amplifier was designed and fabricated, which exhibited a noise figure less than 3 dB with a gain higher than 10 dB over 59.5 to 61.5 GHz range. For the module fabrication, two MMIC chips were mounted in a WR-15 waveguide housing. The four-stage amplifier module demonstrated a noise figure of 4 dB and a gain higher than 24 dB from 59 to 60 GHz. To our knowledge, this is the best reported noise figure including a microstrip-to-waveguide transition loss, using GaAs-based MMICs operating at this frequency range. The measured output power for the module at 1 dB gain compression point was 4 dBm. Temperature test from -20 to 70/spl deg/C revealed very small noise figure and gain variations of 0.35 dB and 0.62 dB, respectively.
Energy sensitization in erbium-doped silicon-rich oxide films annealed at low temperatures (2005)

Si-rich SiO/sub 2/ films (SRO) and Er-doped, Si-rich SiO/sub 2/ films (EnSRO) were deposited by reactive RF magnetron co-sputtering followed by thermal annealing in a nitrogen atmosphere in order to investigate the optimum condition for efficient 1.54 /spl mu/m emission. Reference Er in stoichiometric SiO/sub 2/ (Er:SiO/sub 2/) films were deposited for comparison. The room temperature photoluminescence intensity of SRO films without Er was found to be maximized at 38 at% Si after annealing at 1100/spl deg/C for 1 hour. On the contrary, we found that the maximized Er photoluminescence of Er:SRO with 38 at% Si and an Er concentration of 10/sup 20/ cm/sup -3/ occurred for annealing temperatures between 600/spl deg/C and 800/spl deg/C. Under these conditions the 1.54 /spl mu/m Er emission is enhanced by more than two orders of magnitude relative to Er:SiO/sub 2/ samples while negligible SRO emission is observed.

In-situ real time monitoring of the polymerization in gel-cast ceramic processes (1996)

Gelcasting requires making a mixture of a slurry of ceramic powder in a solution of organic monomers and casting it in a mold. Gelcasting is different from injection molding in that it separates mold filling from setting during conversion of the ceramic slurry to a formed green part. In this work, NMR spectroscopy and imaging were used for in-situ monitoring of the gelation process and gelcasting of alumina. {sup 1}H NMR spectra and images are obtained during polymerization of a mixture of soluble reactive acrylamide monomers. Polymerization was initiated by adding an initiator and an accelerator to form long- chain, crosslinked polymers. Multidimensional NMR imaging was used for in-situ monitoring of the process and for verification of homogeneous polymerization. Comparison of the modeled intensities with acquired images shows a direction extraction of T{sub 1} data from the images.
Protein expression and gene editing in monocots using foxtail mosaic virus vectors (2019)

Plant viruses can be engineered to carry sequences that direct silencing of target host genes, expression of heterologous proteins, or editing of host genes. A set of foxtail mosaic virus (FoMV) vectors was developed that can be used for transient gene expression and single guide RNA delivery for Cas9-mediated gene editing in maize, <i>Setaria viridis</i>, and <i>Nicotiana benthamiana</i>. This was accomplished by duplicating the FoMV capsid protein subgenomic promoter, abolishing the unnecessary open reading frame 5A, and inserting a cloning site containing unique restriction endonuclease cleavage sites immediately after the duplicated promoter. The modified FoMV vectors transiently expressed green fluorescent protein (GFP) and bialaphos resistance (BAR) protein in leaves of systemically infected maize seedlings. GFP was detected in epidermal and mesophyll cells by epifluorescence microscopy, and expression was confirmed by Western blot analyses. Plants infected with FoMV carrying the <i>bar</i> gene were temporarily protected from a glufosinate herbicide, and expression was confirmed using a rapid antibody-based BAR strip test. Expression of these proteins was stabilized by nucleotide substitutions in the sequence of the duplicated promoter region. Single guide RNAs expressed from the duplicated promoter mediated edits in the <i>N. benthamiana Phytoene desaturase</i> gene, the <i>S. viridis Carbonic anhydrase 2</i> gene, and the maize <i>HKT1</i> gene encoding a potassium transporter. The efficiency of editing was enhanced in the presence of synergistic viruses and a viral silencing suppressor. This work expands the utility of FoMV for virus-induced gene silencing (VIGS), virus-mediated overexpression (VOX), and virus-enabled gene editing (VEdGE) in monocots.
