An Interactive System based on Yes-No Questions for Affective Image Retrieval (2015)

We propose an interactive system based on yes-no questions for affective image retrieval. We propose two querying methods, a question generation method, Affective Question and Answer (AQA), and a feedback method, Affective Feedback (AF). Conventional image search systems ask users to input queries by text. However, it is not always easy for users to convert their intention into verbal representations. Especially, the query generation becomes even more difficult when a user tries to find images with affective words due to its subjectivity. In addition, it is not guaranteed that the images are properly annotated with enough number and high quality of tags. To solve these problems, we propose a yes-no questions-based image retrieval system that can effectively narrow down the candidate images. We also provide an affective feedback interface in which users can do the fine tuning of weights of the affective words. We conducted experiments on image retrieval task with 117,866 images. The results showed that our system brings satisfactory results to users in case where the proper text querying is difficult.
Digital compensation of imperfect pump counter-phasing induced phase distortion in optical phase conjugation of high-order QAM (2021)

We propose a new two-stage digital signal processing scheme to suppress the phase distortion that arises from imperfect pump counter-phasing in a dual-pump fibre-based optical phase conjugation system. We demonstrate experimentally and numerically a signal-to-noise ratio improvement of more than 4 dB relative to conventional phase noise compensation, when the proposed scheme is used with 16/64/256 quadrature-amplitude modulation signals at pump-phase mismatch values as large as 8<sup>°</sup>.
Purification and Properties of NADPH-Linkedl-Sorbose Reductase fromGluconobacter melanogenusN44-1 (1991)

NADPH-Linked l-sorbose reductase from the cytosol fraction of Gluconobacter melanogenus N44-1, which is a 2-keto-l-gulonic acid producer from l-sorbose or d-sorbitol, was purified about 500-fold by DEAE-Cellulose, Blue Sepharose, and DEAE-Sepharose column chromatographies. The purified enzyme was entirely homogeneous on polyacrylamide gel and SDS gel electrophoresis. NADPH and NADP were specifically required for the reduction and oxidation of the substrate, respectively. The apparent molecular weight was 60,000 by Sephadex G-200 column chromatography, and that of its subunit was 60,000 by SDS-gel electrophoresis. The pH optimum for the reduction of l-sorbose and d-fructose was 7.0. The pH optimum for the oxidation of d-sorbitol to l-sorbose and d-mannitol to d-fructose was 10.0–10.5.
A Drug Carrier for Sustained Zero-Order Release of Peptide Therapeutics (2017)

Peptides have great potential as therapeutic agents, however, their clinic applications are severely hampered by their instability and short circulation half-life. Zero-order release carriers could not only extend the circulation lifetime of peptides, but also maintain the plasma drug level constant, and thus maximize their therapeutic efficacy and minimize their toxic effect. Here using PEGylated salmon calcitonin (PEG-sCT)/tannic acid (TA) film as an example, we demonstrated that hydrogen-bonded layer-by-layer films of a PEGylated peptide and a polyphenol could be a platform for zero-order peptide release. The films were fabricated under mild conditions. The second component, TA, is a natural product and presents potential therapeutic activities itself. Unlike common carriers, the new carrier releases the peptide via gradual disintegration of the film because of its dynamic nature. The release of PEG-sCT follows a perfect zero-order kinetics without initial burst release. In addition the release rate could be tuned via external stimuli, such as pH and temperature. When implanted in rats, the films could remain the plasma level of PEG-sCT constant over an extended period. Accordingly, the serum calcium level was reduced and maintained constant over the same period, suggesting an improved therapeutic efficacy of the released drug.
<title>Single-ion implantation for solid state quantum computer development</title> (2002)

Several solid state quantum computer schemes are based on the manipulation of electron and nuclear spins of single donor atoms in a solid matrix. The fabrication of qubit arrays requires the placement of individual atoms with nanometer precision and high efficiency. In this article we describe first results from low dose, low energy implantations and our development of a low energy (<10 keV), single ion implantation scheme for <SUP>31</SUP>P<SUP>q+</SUP> ions. When <SUP>31</SUP>P<SUP>q+</SUP> ions impinge on a wafer surface, their potential energy (9.3 keV for P<SUP>15+</SUP>) is released, and about 20 secondary electrons are emitted. The emission of multiple secondary electrons allows detection of each ion impact with 100% efficiency. The beam spot on target is controlled by beam focusing and collimation. Exactly one ion is implanted into a selected area avoiding a Poissonian distribution of implanted ions.
Low-power adaptive filter (2002)

Applications for real-time adaptive filtering techniques are in such diverse fields as adaptive control, ghost cancellation in TV transmission, channel equalization for communication and magnetic recording and estimation/prediction for speech recognition. A block diagram of a ghost-cancellation system for terrestrial and cable TV transmission is shown. The single-chip adaptive filter based on an integrated CCD and CMOS implementation described combines the power and weight advantages of charge-domain computing units with the versatility and adaptability offered by digital control and memory units to achieve a low-power implementation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Reduced Myocardial Velocities of Left Ventricular Long-Axis Contraction Identify Both Systolic and Diastolic Heart Failure—A Comparison with Brain Natriuretic Peptide (2004)

Abstract Background Echocardiographic diagnosis of radial fractional shortening or global ejection fraction fails to diagnose all patients with heart failure; about 40%, with apparently normal global systolic function, will have elevated brain natriuretic peptide (BNP) concentrations and “pure” diastolic dysfunction. Screening methods do not include assessment of left ventricular (LV) longitudinal function, however, which is a more sensitive marker of subclinical disease. Aims We investigated the diagnostic potential of assessment of LV longitudinal function in suspected heart failure, in a comparison against BNP. Methods Fifty consecutive subjects (aged 65±12 years; 30 men) referred to a heart failure clinic with unexplained breathlessness were examined by echocardiography and had plasma BNP measured by fluorescence immunoassay. Results Global systolic function (ejection fraction) correlated moderately with log-transformed BNP (r=−0.54), as did global diastolic function (r=0.55 for estimated LV filling pressure, and r=−0.51 for transmitral flow propagation velocity), and radial systolic function (r=−0.60) (all p&amp;lt;0.001). The echocardiographic parameter that correlated best with BNP, however, was LV longitudinal systolic function (r=−0.78, p&amp;lt;0.001). By stepwise multiple regression analysis, BNP was predicted by longitudinal systolic velocity, in association with LV mass index and radial systolic velocity (r=0.81, r2=0.66, p&amp;lt;0.0001). The sensitivity and specificity of a longitudinal systolic velocity of ≤5.5 cm/s (mean of 4 basal segments) to diagnose heart failure (defined as an elevated BNP) were 94% and 85%, respectively; the negative predictive value was 97%. Conclusion Non-invasive diagnosis or exclusion of suspected heart failure, whether systolic or diastolic, can be performed accurately by echocardiographic measurement of LV longitudinal systolic function.
Time-critical database scheduling: a framework for integrating real-time scheduling and concurrency control (2003)

A framework is presented for analysis of time-critical scheduling algorithms. The main assumptions are analyzed behind real-time scheduling and concurrency control algorithms, and a unified approach is proposed. Two main classes of schedulers are identified according to the availability of information about resource requirements and execution times: conflict-resolving schedulers resolve conflicts at run-time, and hence can only produce a sequence of operations satisfying task priorities and resource constraints; and conflict-avoiding schedulers determine resource requirements and expected execution times through offline transaction-class preanalysis and produce a complete time-critical schedule satisfying both timing and resource constraints. For the latter case, the resolution of overload is essential. Examples are given to illustrate the framework and the main classes of scheduling algorithms.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Personal Data Trading Scheme for Data Brokers in IoT Data Marketplaces (2019)

With the widespread use of the Internet of Things, data-driven services take the lead of both online and off-line businesses. Especially, personal data draw heavy attention of service providers because of the usefulness in value-added services. With the emerging big-data technology, a data broker appears, which exploits and sells personal data about individuals to other third parties. Due to little transparency between providers and brokers/consumers, people think that the current ecosystem is not trustworthy, and new regulations with strengthening the rights of individuals were introduced. Therefore, people have an interest in their privacy valuation. In this sense, the willingness-to-sell (WTS) of providers becomes one of the important aspects for data brokers; however, conventional studies have mainly focused on the willingness-to-buy (WTB) of consumers. Therefore, this paper proposes an optimized trading model for data brokers who buy personal data with proper incentives based on the WTS, and they sell valuable information from the refined dataset by considering the WTB and the dataset quality. This paper shows that the proposed model has a global optimal point by the convex optimization technique and proposes a gradient ascent-based algorithm. Consequently, it shows that the proposed model is feasible even if the data brokers spend costs to gather personal data.
<title>Thermo-electro-mechanical modeling and structural response of a flexible beam with external SMA actuators</title> (1995)

A thermo-electrical and thermo-mechanical model is developed to predict a shape memory alloy (SMA) tendon-actuated compliant beam structure. A geometrically non-linear static analysis is first carried out to investigate the deformed shape of a flexible beam with a SMA tendon actuated electrically. It is found that, when the beam tip deflection is less than 10% of its length, an approximate linear beam model is appropriate, allowing the use of linear beam theory in modeling the dynamic structural response. While the model with nonlinear beam theory is still preferred in model prediction, identification and for full understanding of structure behaviors. The actuation force applied by the SMA actuator to the beam is evaluated by using a thermodynamically based thermomechanical constitutive model for SMA. To calculate the temperature history in the SMA actuator for given electrical current input, the heat conduction equation in the SMA actuator is solved with the electrical resistive heating being modeled as a distributed heat source. Finally, the three steps in the formulation are connected through an iterative scheme that takes into account the static equilibrium of the beam, thus translating an input electrical current history into a beam strain output. The predictions of the proposed model are correlated with experimental results.

Activation of the external urethral sphincter central pattern generator by a 5-HT1A receptor agonist in rats with chronic spinal cord injury (2007)

We recently demonstrated that treatment with the 5-HT(1A/7) receptor agonist [(R)-(+)-8-hydroxy-2-di-n-propylamino]tetralin (8-OH-DPAT) increases bladder capacity in chloralose-anesthetized female cats with chronic spinal cord injury. In the current study, we investigated the effects of 8-OH-DPAT on bladder capacity and external urethral sphincter (EUS) activity in urethane-anesthetized female rats (initial body mass 175-200 g) with chronic spinal cord injury (transsection at T10). Cystometric study took place 8-12 wk posttranssection. Intravesical pressure was monitored in urethane-anesthetized rats with a transvesical catheter, and EUS activity was assessed electromyographically. Spinal cord injury disrupts phasic activity of the EUS, resulting in decreased voiding efficiency and increased residual volume. 8-OH-DPAT induced a dose-dependent decrease in bladder capacity (the opposite of its effect in chronic spinal cord-injured cats) with an increase in micturition volume and decrease in residual volume resulting from improvement in voiding efficiency. The unexpected improvement in voiding efficiency can be explained by the 8-OH-DPAT-induced emergence of phasic EUS relaxation. Phasic EUS relaxation was also altered by 8-OH-DPAT in spinally intact rats, whereas the 5-HT(1A) receptor antagonist N-tert-butyl-3-[4-(2-methoxyphenyl)-piperazin-1-yl]-2-phenylpropanamide (WAY-100635), on its own, was without effect. It remains to be determined when phasic relaxation is restored after spinal cord injury, and indeed whether it is ever truly lost or is only temporarily separated from excitatory input.
Photo-Conductivity Lock-In: A Qualitative and Quantitative Analysis of Measurement Results (2008)

Photo-conductivity lock-in is a technique developed in our laboratories for the analysis of recombination details in semiconductors. Thanks to its high sensitivity, it enables the study of generation/recombination processes at low levels of carrier injection, allowing thus an effective evaluation of the influence of the artificial effects intrinsic in photo-conductivity based lifetime measurement. Such effects, which can be partially explained by minority carrier trapping and depletion region modulation (DRM) effects at surfaces and/or at charged defects, may well conceal the actual recombination lifetime values, but, on the other hand, do provide a source of information on the material, for which careful interpretation is needed. In this work, the relationship between the measurement methodology, the recombination parameters and the experimental results is presented and discussed both in a qualitative and quantitative manner.

Kernel-Based Learning-Aided Phase Noise Compensation in Dual-Pump Optical Phase Conjugation Coherent System (2021)

We deploy kernel-based time-series prediction to suppress the phase noise induced by small deviations from ideal pump counter-phasing in a dual-pump optical phase conjugation system. We show experimentally 1.5-dB SNR improvement for 16-QAM signals at 4° pump-phase mismatch.
Angle-based indoor positioning system for open indoor environments (2009)

In this paper we present a Direction-of-Arrival (DoA) based system which is used for indoor positioning applications. The proposed system has been designed for locating transmitter tags/mobile phones in open indoor locations, such as conference centers, expo areas, and warehouses. A description of both the system architecture and the DoA-based indoor-positioning algorithm are given. In order to demonstrate the system performance, real-world measurements have been carried out. As shown by experimental results, the proposed system provides reliable indoor positioning estimates.

Speeding-Up P-256 ECDSA Verification on x86-64 Servers (2019)

ECDSA is a frequently used signature scheme that has attracted a great deal of software and hardware optimization efforts. In particular, the NIST P-256 curve is currently used for most of the TLS communication worldwide. This paper proposes some observations that lead to additional optimizations. The ECDSA verification includes two main bottlenecks: (a) modular inversion (modulo the group order); (b) two scalar-point multiplications on the underlying elliptic curve (the points are the group's generator and the signer's public key). One observation is that when one point is multiplied by more than one scalar, the multiplications can be accelerated by precomputing some intermediate values. For example, OpenSSL stores a hard-coded multiplication table for the generator of the NIST P-256 curve. Another observation leveraged here is the fact that ECDSA verification uses only public information, and therefore side channel mitigation techniques are not necessary. We show how these observations lead to a speedup of 3.4× over the NIST P-256 ECDSA verification of OpenSSL [1], using ~150 Kb of additional memory space. Some of the optimizations that are offered here, have been recently integrated into BoringSSL [2], [3] achieving a 1.15× speedup over its previous implementation.
Impact of wafer thinning on front-end reliability for 3D integration (2016)

The impact of wafer thinning down to 5 μm Si thickness is assessed in advanced planar and finFET CMOS technologies. Both Bias Temperature Instability (BTI) and Electrostatic Discharge (ESD) reliability are not impacted by the reduction of the substrate thickness.
A 125 mW 8.5–11.5 Gb/s serial link transceiver with a dual path 6-bit ADC/5-tap DFE receiver and a 4-tap FFE transmitter in 28 nm CMOS (2016)

This paper describes an 8.5-11.5 Gb/s transceiver with a dual path receiver and a voltage-mode transmitter. The RX can operate either in ADC mode for complex loss channels such as optical multimode fiber or in DFE mode for copper-based backplane links. The ADC path implements a 2X interleaved 6-bit rectifying flash ADC using a programmable gain amplifier (PGA) with controlled bandwidth and peaking, comparator pipelining, and super-source follower circuit techniques. The LRM optical sensitivity requirements are met with a > 6 dB margin while achieving an ENOB of 4.59 bits at a 5 GHz input frequency. The TX/RX DFE path achieves copper channel loss compensation of 38 dB with BER <; 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-12</sup> at 11.5 Gb/s consuming 46mW from a 0.9V supply.

Retrieval Analysis of a Cementless Modular Total Hip Arthroplasty Prosthesis (2007)

This paper reports the analysis of a modular S-ROM hip implant, which was retrieved at revision, secondary to aseptic loosening approximately after 24 months of implantation. Light microscopy and scanning electron microscopy confirmed the presence of pitting, fretting corrosion, plastic deformation, and stress induced corrosion cracking. Energy dispersive X-ray microanalysis of the stem surface revealed the release of metal ions secondary to environmental interaction. High resolution inductively coupled plasma mass spectroscopy performed on the blood serum sample confirmed the elevated titanium ion levels (4.66 ppb). Finite element analysis of the implant showed that the micromotion and stress levels were the maximum at the proximal lateral region of the taper junction, in congruence with the observation. This case shows that taper performance is influenced by implant's metallurgy and geometry. Patient weight, activity level, and effect of the local microenvironment also play a significant role.
Genome-wide association analyses identify two susceptibility loci for pachychoroid disease central serous chorioretinopathy (2019)

The recently emerged pachychoroid concept has changed the understanding of age-related macular degeneration (AMD), which is a major cause of blindness; recent studies attributed AMD in part to pachychoroid disease central serous chorioretinopathy (CSC), suggesting the importance of elucidating the CSC pathogenesis. Our large genome-wide association study followed by validation studies in three independent Japanese and European cohorts, consisting of 1546 CSC samples and 13,029 controls, identified two novel CSC susceptibility loci: <i>TNFRSF10A-LOC389641</i> and near <i>GATA5</i> (rs13278062, odds ratio = 1.35, <i>P</i> = 1.26 × 10<sup>-13</sup>; rs6061548, odds ratio = 1.63, <i>P</i> = 5.36 × 10<sup>-15</sup>). A T allele at <i>TNFRSF10A-LOC389641</i> rs13278062, a risk allele for CSC, is known to be a risk allele for AMD. This study not only identified new susceptibility genes for CSC, but also improves the understanding of the pathogenesis of AMD.
The influence of the liquid crystalline core geometry on the mesogenicity of novel chiral 2-(4-substituted-phenoxy)propanonitriles (1994)

Abstract The synthesis and characterization of seven novel (R)-2-(4-substituted-phenoxy)propanonitriles are described. The propanonitriles were prepared to evaluate their potential use as thermochromics and ferroelectric dopants, as well as to determine their twist sense properties. The materials exhibit smectic and chiral nematic phases of high thermal stability; the mesogenic behaviour of the nitriles is directly related to the type of two-ring core unit employed. The effects of the different molecular geometries and polarizabilities of the liquid crystalline cores on mesophase stability are discussed, particularly in relation to other members of this series. The chiral nematic phase of the propanonitriles is assigned as having a left-handed twist sense from contact preparation studies, and this is in agreement with rules relating absolute configuration and molecular structure to helical twist sense.
