Microwave-coupled superconducting devices for sensing and quantum information processing (2015)

Superconducting circuits and devices have unique properties that make them interesting from both theoretical and practical perspective. In a superconductor cooled below its critical temperature, electrons bound in Cooper pairs have the ability to carry current without dissipation. A structure where the Cooper pairs are coherently tunneling across a weak link is called a Josephson junction (JJ). The dissipationless and non-linear character of the JJ has found applications, e.g., in microwave amplifiers and quantum circuits. These two subjects are closely related since superconducting quantum bits (qubits) are artificial atoms with a transition spectrum in the microwave range. Mediated by microwave photons, qubit readout in circuit quantum electrodynamics (cQED) architecture requires signal boosting with a low-noise preamplifier. In this thesis, a new type of ultrasensitive JJ microwave amplifier was characterized and its noise performance was found to be close to a bound set by quantum mechanics. The amplifier uses the intrinsic negative differential resistance of a current-biased JJ. &#13;\nThis work also addressed a challenge related to the scalability of the cQED architecture when the qubits are weakly anharmonic. In a frequencycrowded multi-qubit system, driving individual qubits may cause leakage into non-computational levels of the others. Leakage-avoiding single-qubit Wah-Wah control was implemented. At maximum gate speed corresponding to the frequency crowding, microwave control of two transmon qubits on a 2D cQED quantum processor was decoherence limited. The results disclose the usefulness of Wah-Wah in a future quantum computing platform. &#13;\nQuasiparticles are excitations from the paired superconducting ground state of conduction electrons. As the third topic, the generation-recombination dynamics of quasiparticles was employed in sensing. In electrodynamical terms, superconducting thin films have kinetic inductance from the inertia of the Cooper pairs and resistive dissipation from the quasiparticles. If the film is a part of an electrical resonator, quasiparticle density steers its microwave eigenfrequency and quality factor. In this work, submillimetre-wave radiation and external magnetic field were first converted into quasiparticlegenerating temperature variations and screening currents in a superconductor, respectively. In the two devices called kinetic inductance bolometer and magnetometer, the corresponding changes in resonator parameters were read out to extract the encoded signal. Sensor characterization indicated potential for high sensitivity and low noise. Future applications of the bolometer and the magnetometer include security screening and biomagnetism, respectively. Here, multiplexability in frequency domain facilitates the scale-up to large sensor arrays.

Advanced ultrapure water systems with low dissolved oxygen for native oxide free wafer processing (1992)

In the manufacture of submicron or deep submicron ULSIs, it is important to completely suppress native oxide growth on the silicon wafer surfaces. In a wet process, dissolved oxygen must be removed from the ultrapure water used for the final rinsing of the wafer. Two independent systems for the supply of ultrapure water, augmented with new techniques to remove dissolved oxygen, have been installed in the mini-super-clean room at Tohoku University. Both systems use two-stage dissolved oxygen removing methods. System one uses vacuum degassing through membrane and catalytic resin-based reduction, while system two uses vacuum degassing through membrane and nitrogen gas bubbling. Both systems can supply ultrapure water of 10 ppb or less in dissolved oxygen concentration. The concentrations of other impurities such as TOC, silica and total residue are also 1 ppb or less.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Usefulness of 99mTc-labeled RBC scan and SPECT in the diagnosis of head and neck hemangiomas (2009)

2106 Objectives There have been various methods to diagnose hemangioma, such as US, CT, MRI and Nuclear Medicine. Due to the development of SPECT imaging, however, the blood-pool scan using 99mTc-labeled RBC scan has been frequently used, since it is non-invasive and the most economical method of all. Therefore, we propose to investigate the head and neck in diagnosing hemangiomas. Methods Scan and SPECT was performed on 6 suspected patients of hemangioma(4-head; 1-neck; 1-another). We prepared a radiopharmaceutical using modified in vivo method. After a bolus injection of tracer, the images of dynamic perfusion flow were acquired. Then, anterior, posterior and both lateral static blood-pool images were obtained at this point, and then 4 hours later again. SPECT was integrated in 64 projections and 30 seconds. Each image was interpreted by physicians, nuclear medicine specialist, and technologist blinded to patient9s data. Results As for 5 suspected patients, there was no change in flow, but increases in blood-pool, delayed and SPECT. So, it was a typical hemangioma finding. The size of lesion was over 2 cm, and it is clearly discriminated when it is compared to the delayed and SPECT imaging. On the other hand, as for the other 1 patient, the radioactivity was increased in blood-pool, not in delayed and SPECT, though. Therefore, it was proved to be not hemangioma. Conclusions We diagnose the hemangiomas in head and neck, as well as, liver, rather non-invasively, economically, and easily. Therefore, it is considered that 99mTc-RBC Scan and SPECT offer more useful information for diagnosis of hemangioma, rather than other imaging.
Low dose cyclosporine A in psoriatic arthritis: relation between soluble interleukin 2 receptors and response to therapy. (1992)

Twelve patients with psoriatic arthritis (PsA) were treated with low doses of cyclosporine A (CsA) (the initial dose was 3 mg/kg daily) and were entered into an open 6-month study. At the end of the study arthritis was improved in 7 patients (number of patients achieving a 50% or more reduction in the number of swollen or tender joints) and unchanged in 4 patients. Cutaneous psoriasis also improved significantly as shown by psoriasis area and severity index score. Only one patient withdrew from the study after one month because of severe nephrotoxicity. Serum creatinine fell to baseline value 6 weeks after the discontinuation of CsA. Three patients had minor side effects. CsA maintained articular improvement also in the 9 patients who are still taking this drug (mean duration of therapy of 12 +/- 0.8 months). There was no significant reduction of erythrocyte sedimentation rate during the study period. We assayed levels of soluble interleukin 2 receptors (sIL-2R) in serial serum samples obtained from 10 patients during the study period. Concentrations of sIL-2R were significantly increased in patients with PsA compared to controls. In 6 responder patients we observed a parallel decrease in joint pain/tenderness score and serum sIL-2R values. This finding was not observed in 4 nonresponders. Our results suggest that low dose CsA is a short term effective and safe therapy in patients with PsA and that serial sIL-2R levels are a useful means of measuring changes in disease activity.
Optical analog link using a linearized modulator (2002)

Many of the applications of optical analog links, such as antenna remoting and phased array antenna control, involve bandwidths of less than one octave. In these cases, the modulator may be optimized without the constraint of minimizing second-order distortion. This leads to a simple linearized modulator design that minimizes third-order distortion while providing a link noise figure as low as a link with a standard interferometric modulator using the same input laser power. The average detector current (bias-point photocurrent) can be kept low to accommodate small-area microwave detectors and to minimize the effects of optical intensity noise. The modulator consists of two standard Mach-Zehnder interferometric modulators (MZs) in series.
Metabolic fate of adenine in red blood cells during storage in SAGM solution (2016)

In this work, we have studied in detail the metabolic fate of adenine during RBC storage in SAGM. Adenine is one of the main substrates used by RBCs, but the metabolic shift observed during storage is not caused by an absence of adenine later in storage. The rate of adenine consumption strongly correlated with duration of storage but not with the amount of adenine present in the AS.
A New PWM Strategy for Grid-Connected Half-Bridge Active NPC Converters With Losses Distribution Balancing Mechanism (2015)

Photovoltaic systems technological development is driven by the request for higher efficiency and safety. These concerns influence also the choice of the power converter stage. Several topologies have been proposed and many of them are available commercially. Among them, the neutral point clamped (NPC) and derived topologies offers high efficiency, low leakage current, and low EMI. However, one main disadvantage of the NPC inverter is given by an unequal distribution of the losses in the semiconductor devices, which leads to an unequal distribution of temperature that can affect lifetime. By using the active NPC (ANPC) topology, where the clamping diodes are replaced by bidirectional switches, the power losses distribution problem is alleviated. The modulation strategy is a key issue for losses distribution in this topology. In this paper, two known strategies are discussed and a new PWM strategy, namely the adjustable losses distribution is proposed for better losses distribution in the ANPC topology. Simulations and experimental results help in evaluating the modulation strategies.
Television Time and Continuous Metabolic Risk in Physically Active Adults (2008)

In a population of healthy Australian adults who met the public health guideline for physical activity, television-viewing time was positively associated with a number of metabolic risk variables. These findings support the case for a concurrent sedentary behavior and health guideline for adults, which is in addition to the public health guideline on physical activity.
Development of a minimally invasive microvascular ischemia monitor: noise and artifact extraction (2003)

Long-term postoperative pH monitoring of transplanted tissue for ischemia produces signals contaminated with noise and artifacts of various origins. Clinical interpretation of these pH recordings is difficult. The objective of our research is to determine the optimal filtering parameters for tissue pH signals to extract and reject the artifacts. The noise components present in long-term pH recordings were identified, extracted, and analyzed. Frequency ranges of identified artifact types were determined. Parameters were defined to effectively characterize each of the components by frequency, amplitude, and peak to peak slope. Based on the artifact analysis, it was concluded that to achieve clinical usefulness, only motion and position artifacts need to be rejected from the signal, while the influences of the "24 hour component" and drift are insignificant.
The Fission Yeast Jmj2 Reverses Histone H3 Lysine 4 Trimethylation (2007)

Histone methylation regulates transcription, chromatin structure, and the epigenetic state of the cell. Recent studies identified the JmjC domain as a catalytic module for histone demethylation. Schizosaccharomyces pombe contains seven JmjC proteins, but it was unclear whether any of them functioned as histone demethylases. In this report, we show that the JmjC protein Jmj2, which is evolutionarily conserved from yeast to human, reversed trimethylated H3-Lys-4 to di- and mono-but not unmethylated products. Overexpression of Jmj2 but not a catalytically inactive mutant reduced H3-Lys-4 trimethylation levels in vivo and suppressed the toxicity caused by overexpression of the H3-Lys-4-me3-binding protein Yng1 in budding yeast. Genome-wide analysis showed that the loss of jmj2 was associated with an increase in the H3-Lys-4-me3 signal, which was enriched near the transcriptional start sites and the coding regions. At the mating-type locus, the loss of jmj2 or substitution of jmj2 with a catalytically inactive form is correlated with increased reporter gene transcription and H3-Lys-4-me3/2 levels, suggesting that Jmj2 and its demethylase activity may play a role in heterochromatin biology. Our findings identified a novel S. pombe histone demethylase with specificity toward di- and trimethylated histone H3-Lys-4 and a possible role in heterochromatin regulation.
MCTS With Refinement for Proposals Selection Games in Scene Understanding (2022)

We propose a novel method applicable in many scene understanding problems that adapts the Monte Carlo Tree Search (MCTS) algorithm, originally designed to learn to play games of high-state complexity. From a generated pool of proposals, our method jointly selects and optimizes proposals that minimize the objective term. In our first application for floor plan reconstruction from point clouds, our method selects and refines the room proposals, modelled as 2D polygons, by optimizing on an objective function combining the fitness as predicted by a deep network and regularizing terms on the room shapes. We also introduce a novel differentiable method for rendering the polygonal shapes of these proposals. Our evaluations on the recent and challenging Structured3D and Floor-SP datasets show significant improvements over the state-of-the-art both in speed and quality of reconstructions, without imposing hard constraints nor assumptions on the floor plan configurations. In our second application, we extend our approach to reconstruct general 3D room layouts from a color image and obtain accurate room layouts. We also show that our differentiable renderer can easily be extended for rendering 3D planar polygons and polygon embeddings. Our method shows high performance on the Matterport3D-Layout dataset, without introducing hard constraints on room layout configurations.
Observation of contact resistivity independence from Schottky barrier height on heavily doped p-type SiGe (2016)

The electrical characteristics of Ti/p-SiGe contacts with Ti thicknesses of 3nm and 5nm have been investigated in this paper. TiN was used as a cap layer on Ti. It is observed that as Ti film becomes thinner, Ti/p-SiGe contact resistivity (ρc) increases, but its Schottky barrier height (SBH) decreases, which does not coincide with the regular ρc-SBH dependence. Using TiN/p-SiGe as a control sample, it is concluded that when Ti film is thinned down to nm scale, the contact property is strongly influenced by TiN cap layer.

Joint Source-Channel Coding for the MIMO Broadcast Channel (2011)

We investigate the problem of broadcasting analog sources to several users using short codes, employing several antennas at both the transmitter and the receiver, and channel-optimized quantization. Our main objective is to minimize the sum mean-square error distortion. A joint multi-user encoder, as well as a structured encoder with separate encoders for the different users, are proposed. The first encoder outperforms the latter, which, in turn, offers large improvements compared to state-of-the-art, over a wide range of channel signal-to-noise ratios. Our proposed methods handle bandwidth expansion, i.e., usage of more channel than source dimensions, automatically. We also derive a lower bound on the distortion.
Prospective discovery of small molecule enhancers of an E3 ligase-substrate interaction (2019)

Protein-protein interactions (PPIs) governing the recognition of substrates by E3 ubiquitin ligases are critical to cellular function. There is significant therapeutic potential in the development of small molecules that modulate these interactions; however, rational design of small molecule enhancers of PPIs remains elusive. Herein, we report the prospective identification and rational design of potent small molecules that enhance the interaction between an oncogenic transcription factor, β-Catenin, and its cognate E3 ligase, SCF<sup>β-TrCP</sup>. These enhancers potentiate the ubiquitylation of mutant β-Catenin by β-TrCP in vitro and induce the degradation of an engineered mutant β-Catenin in a cellular system. Distinct from PROTACs, these drug-like small molecules insert into a naturally occurring PPI interface, with contacts optimized for both the substrate and ligase within the same small molecule entity. The prospective discovery of 'molecular glue' presented here provides a paradigm for the development of small molecule degraders targeting hard-to-drug proteins.
Hydrodynamics and Gas Dispersion Characterization in a System Equipped with a New Gas‐Inducing Impeller (2003)

Abstract A new agitation system, called Turboxal, used for the oxygenation and the mixing of wastewater biological treatment tanks has been studied. The interactions between the shell and the three impellers which compose the Turboxal have been analyzed by single‐phase flow patterns. The pumping capacity and the power consumption have also been measured. In addition, the gas dispersion regimes have been analyzed in the tank and in the shell. Finally, the effect of the interaction and the effect of the position of the different agitators on the limit of the flooding regime have been determined.
SEUS (2016)

With the prevalence of smartphones, pedestrians and joggers today often walk or run while listening to music. Since they are deprived of their auditory senses that would have provided important cues to dangers, they are at a much greater risk of being hit by cars or other vehicles. In this demonstration we present SEUS, a wearable system aimed at Sense Enhancement for Urban Safety. SEUS uses a three-stage architecture, consisting of headset mounted audio sensors, an embedded front-end for signal processing and feature extraction, and machine learning based classification on a smartphone, to provide early danger detection for pedestrians in real-time.
An automated, self sustained soil moisture measurement system using low power dual probe heat pulse (DPHP) Sensor (2015)

This paper presents an automated, self sustained, low power in-situ soil moisture measurement system for dual probe heat pulse (DPHP) sensors. The deployed DPHP sensor has two probes: a heater probe and a temperature probe spaced 3 mm apart. Change in the temperature, due to heating, is a function of the soil moisture content. DPHP sensor is integrated with a low power instrumentation board (5mW) for signal amplification, which stores the data in a micro SD card. System automatically turns on the DPHP sensor as well as the instrumentation board at every 1 hour interval for 3 minutes heating cycle, 3 minutes cooling cycle and 54 minutes sleep cycle. Average power consumption during heating cycle is 170mW, one of the lowest powers reported till date. Li-ion battery rated at 3.7V, 1150 mAh capacity is used to power the entire system. The battery is charged by a solar panel, fixed on the top of the system and rated at 6V and 450mA. A PYTHON based GUI is developed for data analysis and presentation utility. Since moisture measurement depends on the structure, mineral and porosity of the soil the system is equipped with a data base in the form of look up tables (LUTs), already produced for various common types of agricultural soil. These LUTs are used for mapping the measured values of change in the temperature from the proposed system to the corresponding soil moisture content. The developed system is able to measure soil moisture content ranging from 1% to 40%. This paper also presents the charging and discharging profile of the battery during in-situ field testing, automatically generated by the system.
The Geode Process I: Hollow Silica Microcapsules as a High Surface Area Substrate for Semiconductor Nanowire Growth (2019)

&lt;div&gt;&lt;div&gt;&lt;div&gt;&lt;p&gt;We introduce and demonstrate critical steps toward the Geode process for the bottom-up synthesis of semiconductor nanowires. Central to the process is the design and fabrication of an unconventional, high surface area substrate: the interior surface of hollow silica microcapsules, assembled from silica particles via emulsion templating, and featuring porous walls to enable efficient gas transport. The interior surface of these hollow silica microcapsules is decorated with gold nanoparticles that seed nanowire growth via the vapor-liquid-solid (VLS) mechanism. We demonstrate the production of the necessary microcapsules and show how microcapsule structure and stability upon drying is influenced by the type of silica particles and use of a particle cross-linking agent. Finally, we demonstrate the synthesis of Si nanowires in the microcapsule interior.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;
