Quantum process tomography of the quantum Fourier transform (2004)

The results of quantum process tomography on a three-qubit nuclear magnetic resonance quantum information processor are presented and shown to be consistent with a detailed model of the system-plus-apparatus used for the experiments. The quantum operation studied was the quantum Fourier transform, which is important in several quantum algorithms and poses a rigorous test for the precision of our recently developed strongly modulating control fields. The results were analyzed in an attempt to decompose the implementation errors into coherent (overall systematic), incoherent (microscopically deterministic), and decoherent (microscopically random) components. This analysis yielded a superoperator consisting of a unitary part that was strongly correlated with the theoretically expected unitary superoperator of the quantum Fourier transform, an overall attenuation consistent with decoherence, and a residual portion that was not completely positive-although complete positivity is required for any quantum operation. By comparison with the results of computer simulations, the lack of complete positivity was shown to be largely a consequence of the incoherent errors which occurred over the full quantum process tomography procedure. These simulations further showed that coherent, incoherent, and decoherent errors can often be identified by their distinctive effects on the spectrum of the overall superoperator. The gate fidelity of the experimentally determined superoperator was 0.64, while the correlation coefficient between experimentally determined superoperator and the simulated superoperator was 0.79; most of the discrepancies with the simulations could be explained by the cumulative effect of small errors in the single qubit gates.
Rapid Fabrication Technique for Interpenetrated ZnO Nanotetrapod Networks for Fast UV Sensors (2013)

Two flame-based synthesis methods are presented for fabricating ZnO-nanostructure-based UV photodetectors: burner flame transport synthesis (B-FTS)and crucible flame transport synthesis (C-FTS). B-FTS allows rapid growth of ZnO nanotetrapods and in situ bridging of them into electrical contacts. The photo detector made from interconnected ZnO nanotetrapod networks exhibits fast response/recovery times and a high current ratio under UV illumination.
Studies on reverse osmosis concentration of cheese whey. Part IV. Theoretical basis for designing the installations and economizing the operation of reverse osmosis concentration of cheese whey. (1989)

多段循環式連続逆浸透(RO)装置を用いて限界安定体積透過流束によりチーズホエーを濃縮する場合の,最小の濃縮総費用を与える最適装置設計要件および最適操作条件を理論的に決定する数学モデルを提案した. 透過液1m3を除去するのに要する濃縮総費用を, (1)体積透過流束の多寡により変動する費用(Cθ)と(2)変動しない費用に分け,これらの費用を求める諸式をROに関わる諸因子の関数として表現した.さらに,輸送方程式,濃度分極式,限界安定体積透過流束とモジュール内循環流量の関数を用いて, ROに関わるこれら諸因子間の関係を表現した.その結果,濃縮倍率と循環流量を与えることによりCθを得る数学モデルを体系化することができた.この数学モデルに各段の濃縮倍率と循環流量の種々の組合せを与えて算出したCθの中から,最小の費用を与える組合せを検索することにより,最適の装置設計要件及び濃縮操作条件を決定することが可能となった. 平面膜型Arlamo-26モジュールとFL-190膜(食塩阻止率0.90)で構成した3段循環式連続RO装置の使用を想定したケーススタディにより,日量100m3のホエーを20時間で3倍濃縮する場合の最適装置設計要件,最適操作条件及び濃縮総費用を求めた.限界安定体積透過流束のデータが得られている4つのケースについて比較した結果,濃縮総費用が最も安価であったのは,pH 5.8のホエーを50℃で1時間保持後40℃で濃縮するケースであった.本ケースにおける透過液1m3当たりの最小濃縮総費用は1140円で,その内訳は高圧フィードポンプ動力費4%,循環ポンプ動力費7%,膜交換費11%,固形物損失費13%,排水処理費1%,洗浄費2%,ホエーの前処理費(pH調整費)8%,人件費16%および設備償却費38%であった. さらに任意の段のCθ(i)を循環流量の関数として表現することができたので,最小の濃縮総費用を与える各段の最適循環流量および最適濃縮倍率を迅速かっ簡便に求めることが可能となった.平面膜型Arlamo-26モジュールとFL-190膜(食塩阻止率0.90)で構成した3段循環式連続RO装置の使用を想定したケーススタディにより,日量100m3のホエーを20時間で3倍濃縮する場合の最適装置設計要件,最適操作条件及び濃縮総費用を求めた.限界安定体積透過流束のデータが得られている4つのケースについて比較した結果,濃縮総費用が最も安価であったのは,pH 5.8のホエーを50℃で1時間保持後40℃で濃縮するケースであった.本ケースにおける透過液1m3当たりの最小濃縮総費用は1140円で,その内訳は高圧フィードポンプ動力費4%,循環ポンプ動力費7%,膜交換費11%,固形物損失費13%,排水処理費1%,洗浄費2%,ホエーの前処理費(pH調整費)8%,人件費16% および設備償却費38%であった.さらに任意の段のCθ(i)を循環流量の関数として表現することができたので,最小の濃縮総費用を与える各段の最適循環流量および最適濃縮倍率を迅速かっ簡便に求めることが可能となった.
Measuring the effects of belief on Kanizsa shape discrimination and illusory contour formation: A replication (2012)

PURPOSE. Prior research has shown that belief about contour connectedness alters global shape integration but not illusory contour formation. Here, we aim to replicate those results while also independently verifying that subjects adopted the instructed belief. METHOD. Subjects discriminated briefly-presented, partly-visible fat and thin shapes, the edges of which either induced or did not induce illusory contours (relatable and nonrelatable condition, respectively). Half of trials of each condition incorporated task-irrelevant distractor lines, which disrupt contour filling-in. Half of the observers were asked to treat the visible parts of the target as belonging to a single thing (group strategy); the other half were asked to treat the parts as disconnected (ungroup strategy). A strategy was encouraged by giving subjects pictures of fat and thin response templates in the experiment instructions, and after every 20 trials. These pictures depicted either unitary shapes or fragmented shapes, depending on strategy. After each half of the experiment, subjects were asked how they cognitively regarded the stimulus. Task-naïve judges evaluated the responses. RESULTS. The results confirmed previous findings. Distractor lines impaired performance more in the relatable condition than in the nonrelatable condition (p=.001). Strategy did not alter the effects of distractor lines in the relatable trials or the nonrelatable trials (ps>.25). The attempt to group relatable fragments improved performance (p=0.004), while the attempt to group nonrelatable fragments did not (p>.5). Finally, 90% of the subjects were evaluated as having adopted the instructed strategy on both halves of the experiment. CONCLUSIONS. These new results show once again that a) filling-in effects during illusory contour formation cannot be easily removed via top-down strategy; b) filling-in effects cannot be easily manufactured from stimuli that fail to elicit interpolation; c) actively grouping fragments can readily improve discrimination performance, but only when those fragments cause interpolation.

A hybrid wordspotting method for spontaneous speech understanding using word-based pattern matching and phoneme-based HMM (2002)

We have proposed a new wordspotting method, combining word-based pattern matching and phoneme-based hidden Markov model (HMM). Word-based pattern matching based on the time-frequency representation of a whole word pattern is robust against pattern variations and background noise, while the phoneme-based HMM, which represents phonemic features within a word pattern, is flexible for expanding the vocabulary. Because of the difference in scope, these two have their own characteristics in terms of robustness and accuracy. To take advantage of the features of these two, we have integrated these different types of wordspotting results under a unified criterion. A syntactic and semantic parser is also utilized to prune the wordspotting results for spontaneous speech understanding. Experimental results indicate the effectiveness of the proposed method.
S‐Trityl‐(R)‐cysteine, a powerful chiral selector for the analytical and preparative ligand‐exchange chromatography of amino acids (2008)

S-trityl-(R)-cysteine [(R)-STC] is the new selector of a dynamically coated, chiral ligand-exchange stationary phase which proved to be highly effective in both analytical and preparative-scale separation of enantiomers of some natural and unnatural underivatized amino acids, with good separation and resolution factors. With the aim of identifying the best chromatographic conditions suitable for the preparative-scale separations, some parameters controlling retention, separation and resolution factors (such as the type and amount of cupric salt and the eluent pH) were investigated. The relatively easy removal of the Cu(II) ions renders this technique suitable for obtaining small amounts of enantiomerically pure samples for preliminary biological evaluations.
Determination of Activities of Daily Living of independent living older people using environmentally placed sensors (2013)

The rapid increase in the ageing population of most developed countries is presenting significant challenges to policymakers of public healthcare. To address this problem, we propose a Smarter Safer Home solution that enables ageing Australians to live independently longer in their own homes. The primary aim of our approach is to enhance the Quality of Life (QoL) of aged citizens and the Family Quality of Life (FQoL) for the adult children supporting their aged parents. To achieve this, we use environmentally placed sensors for non-intrusive monitoring of human behaviour. The various sensors will detect and gather activity and ambience data which will be fused through specific decision support algorithms to extract Activities of Daily Living (ADLs). Subsequently, these estimated ADLs would be correlated with reported and recorded health events to predicate health decline or critical health situations from the changes in ADLs.
Will Mayaro virus be responsible for the next outbreak of an arthropod-borne virus in Brazil? (2017)

Mayaro virus is an alphavirus from the Togaviridae family and is transmitted mainly by Hemagogus mosquitoes. This virus circulates in high-density tropical forests or rural areas of Central and South America causing a disease characterized by high-grade fever, maculopapular skin rash and marked arthralgia that, in some patients, can persist for long periods after infection and may be misinterpreted as chikungunya. Although only a few outbreaks involving this virus have been reported, in the last years the number of Mayaro virus infections has increased in the central and northern regions of Brazil. In this review, we describe the reported prevalence of this infection over the years and discuss the circumstances that can contribute to the establishment of an urban mayaro virus epidemic in Brazil and the problems encountered with the specific diagnosis, especially the antigenic cross-reactivity of this pathogen with other viruses of the same family.
Air‐Pressure‐Assisted Pen‐Nib Printing for 3D Printed Electronics (Adv. Mater. Technol. 6/2022) (2022)

Functional Ink Ejection Air-pressure-assisted pen-nib printing approach can control the functional ink ejection by negative (suction, red arrow) and positive (ejection, blue arrow) air pressure as shown in article number 2101172 by Seung Kwon Seol and co-workers. This new conceptual printing method can produce electrical and functional components with various material inks on non-flat and 3D surfaces, contributing to realize the 3D printed electronic devices.
Mechanisms of Vanadium Recovery from Stone Coal by Novel BaCO3/CaO Composite Additive Roasting and Acid Leaching Technology (2016)

In this report, the vanadium recovery mechanisms by novel BaCO3/CaO composite additive roasting and acid leaching technology, including the phase transformations and the vanadium leaching kinetics, were studied. The purpose of this manuscript is to realize and improve the vanadium recovery from stone coal using BaCO3/CaO as the composite additive. The results indicated that during the composite additive BaCO3/CaO roasting process, the monoclinic crystalline structure of muscovite (K(Al,V)2[Si3AlO10](OH)2) was converted into the hexagonal crystalline structure of BaSi4O9 and the tetragonal crystalline structure of Gehlenite (Ca2Al2SiO7), which could, therefore, facilitate the release and extraction of vanadium. Vanadium in leaching residue was probably in the form of vanadate or pyrovanadate of barium and calcium, which were hardly extracted during the sulfuric acid leaching process. The vanadium leaching kinetic analysis indicated that the leaching process was controlled by the diffusion through a product layer. The apparent activation energy could be achieved as 46.51 kJ/mol. The reaction order with respect to the sulfuric acid concentration was 1.1059. The kinetic model of vanadium recovery from stone coal using novel composite additive BaCO3/CaO could be finally established.
A Direct Catalytic Ethanol Fuel Cell (DCEFC) Modified by LDHs, or by Catalase-LDHs, and Improvement in Its Kinetic Performance: Applications for Human Saliva and Disinfectant Products for COVID-19 (2023)

In this work, it has been experimentally proven that the kinetic performance of a common Direct Catalytic Ethanol Fuel Cell (DCEFC) can be increased by introducing nanostructured (Zn<sup>II</sup>,Al<sup>III</sup>(OH)<sub>2</sub>)<sup>+</sup>NO<sub>3</sub><sup>-</sup>·H<sub>2</sub>O Layered Double Hydroxides (LDHs) into the anode compartment. Carrying out the measurements with the open-circuit voltage method and using a kinetic format, it has been shown that the introduction of LDHs in the anodic compartment implies a 1.3-fold increase in the calibration sensitivity of the method. This improvement becomes even greater in the presence of hydrogen peroxide in a solution. Furthermore, we show that the calibration sensitivity increased by 8-times, when the fuel cell is modified by the enzyme catalase, crosslinked on LDHs and in the presence of hydrogen peroxide. The fuel cell, thus modified (with or without enzyme), has been used for analytical applications on real samples, such as biological (human saliva) and hand disinfectant samples, commonly used for the prevention of COVID-19, obtaining very positive results from both analytical and kinetic points of view on ethanol detection. Moreover, if the increase in the calibration sensitivity is of great importance from the point of view of analytical applications, it must be remarked that the increase in the speed of the ethanol oxidation process in the fuel cell can also be extremely useful for the purposes of improving the energy performance of a DCEFC.
Controlled Organization of Au Colloids into Linear Assemblies (2004)

A simple and convenient method is described to produce gold nanowires. A controlled organization of Au colloids into linear assemblies was achieved without using any templates. HAuCl4 was reduced by NaBH4 in the presence of lysine to act as capping and bridging agent. At a molar ratio of Au/Lys = 1:0.5 and pH in the range 8.4−9.5, linear aggregates of Au can be prepared with a diameter of ca. 5 nm and variable lengths in the range of 80−200 nm. At lower or higher pH values, there is no control on the unidirectional growth of linear aggregates. Application of ultrasound during the preparation also impairs linear growth or disrupts the chain structure, yielding discrete colloidal particles of Au as sole product. The key factor for formation of Au linear assemblies is believed to be a subtle balance between the attractive (cross-linking) force, provided by lysine molecules, working against the electrostatic repulsion among Au colloid surfaces bearing like (negative) charges.
ANNEALING OF SURFACE AND INTERFACE LAYERS CAUSED BY THE PLASMA/SUBSTRATE INTERACTION DURING THE DEPOSITION OF PECVD a-Si:H FILMS (1989)

ANNEALING OF SURFACE AND INTERFACE LAYERS CAUSED BY THE PLASMA/SUBSTRATE INTERACTION DURING THE DEPOSITION OF PECVD a-Si:H FILMS was published in EPM ’89: 3rd International Conference on Energy Pulse and Particle Beam Modification of Materials, September 4.–8. 1989, Dresden, GDR on page 360.
Macroscopic Nanotemplating of Semiconductor Films with Hydrogen‐Bonded Lyotropic Liquid Crystals (2005)

Abstract Aqueous gel‐like lyotropic liquid crystals with extensive hydrogen bonding and nanoscale hydrophilic compartments have been used to define the growth of macroscopic nanotemplated CdS and CdTe thin films. These mesoporous semiconductor films contain a hexagonal array of 2.5 nm pores, 7 nm center‐to‐center, that extend in an aligned fashion perpendicular to the substrate. The CdS is deposited on a polypropylene substrate by a reaction between Cd(NO 3 ) 2 dissolved in the liquid crystal and H 2 S transported via diffusion through the substrate. The CdTe is electrodeposited on indium‐tin‐oxide‐coated glass from TeO 2 and Cd(NO 3 ) 2 , both of which are dissolved in the liquid‐crystal template. The porous nature of the CdTe films enables chemical transformations of the entire bulk of the film. As electrodeposited, the CdTe films are Te rich and, in contrast to a non‐templated film, the excess Te could be removed via a chemical treatment, proving the continuity of the pores in the nanotemplated films. These results suggest that liquid‐crystal lithography with hydrogen‐bonding amphiphiles may be a useful approach to create materials with nanoscale features over macroscopic dimensions.
Correlation of defect centers with a wavelength-dependent photosensitive response in germania-doped silica optical fibers (1991)

We demonstrate a similar wavelength-dependent response for both the generation of Ge E' centers and the formation of photosensitive gratings in germania-doped silica fibers. This supports a model for the grating formation whereby two-photon absorption of laser radiation into the UV bleachable absorption band of an oxygendeficient germania site creates hole traps, modeled as Ge E' centers, which are detectable with electron spin reasonance spectroscopy.
Rocky road to digital diagnostics: implementation issues and exhilarating experiences (2020)

Since 2007, we have gradually been building up infrastructure for digital pathology, starting with a whole slide scanner park to build up a digital archive to streamline doing multidisciplinary meetings, student teaching and research, culminating in a full digital diagnostic workflow where we are currently integrating artificial intelligence algorithms. In this paper, we highlight the different steps in this process towards digital diagnostics, which was at times a rocky road with definitely issues in implementation, but eventually an exciting new way to practice pathology in a more modern and efficient way where patient safety has clearly gone up.
Nanoscale Infrared Spectroscopy of Materials by Atomic Force Microscopy (2010)

The ability to identify material under the tip of an AFM has been identified as one of the ‘Holy Grails’ of scanning probe microscopy. While AFM can measure mechanical, electrical, magnetic and thermal properties of materials, it has lacked the robust ability to chemically characterize unknown materials. Infrared spectroscopy is a benchmark technique used in a broad range of sciences and industry to characterize and identify materials via vibrational resonances of chemical bonds. We have successfully integrated AFM with IR spectroscopy to allow measurement of high quality IR spectra at arbitrary points in an AFM image, thus providing nanoscale chemical characterization.
Refractive Index Change of an Amorphous Bisbenzothienylethene (2001)

A bisbenzothieneylethene exhibiting a photochromic behavior in the amorphous bulk solid state was synthesized. Upon alternate ultraviolet (UV) and visible light irradiation the amorphous thin film underwent a reversible color change and modulation of the refractive index. The refractive index change was determined at 632.8 nm and 817 nm using a prism coupling method. The difference in the refractive index value between the open- and closed-ring isomers was as high as 0.064 at 817 nm.
Indoxyl Sulfate Downregulates Expression of Mas Receptor via OAT3/AhR/Stat3 Pathway in Proximal Tubular Cells (2014)

Mas receptor expression is reduced in the kidneys of CKD rats. IS downregulates renal expression of Mas receptor via OAT3/AhR/Stat3 pathway in proximal tubular cells. IS-induced downregulation of Mas receptor might be involved in upregulation of TGF-β1 in proximal tubular cells.
Dielectric properties of polymer nanocomposite interphases from electrostatic force microscopy using machine learning (2021)

Abstract Interphase regions in polymer nanocomposite materials are difficult to characterize due to their nano-scale dimensions. Electrostatic force microscopy (EFM) provides a pathway to local dielectric property measurements, but extracting local dielectric permittivity in complex interphase geometries from EFM measurements remains a challenge. We demonstrate the efficacy of machine learning (ML) models to extract interphase permittivity using a data set of synthetic EFM force gradient scans generated by finite element simulations. We show that both support vector regression (SVR) and random forest (RF) algorithms are able to ‘invert’ the force gradient scan to predict the permittivity with high accuracy. Feature reduction by principal component analysis (PCA) improves the model's performance and reveals force gradient contrast to be the most important feature in permittivity detection. We find that these ML models perform better than analytical approaches by capturing significant geometric complexity of EFM measurements.
A randomized, controlled trial comparing skin health effects and comfort of two adult incontinence protective underwear (2016)

Background/Purpose It is important to confirm product use effects on skin health for products intended for prolonged skin contact. This study compared experimental and marketed reference adult incontinence protective underwear. Methods Randomized, single‐blind (examiner), parallel study evaluating skin health effects in predominantly obese incontinent women normally using protective underwear (approximately 20% Type II Diabetes). Subjects wore experimental or marketed reference protective underwear daily, 14 consecutive days. Visual skin grading, transepidermal water loss (TEWL) assessed before, after 1 and 2 weeks of product wear. Overall assessment of comfort assessed. Results Of the 122 subjects (60 experimental and 62 marketed reference), 22 were diabetic and 88 were postmenopausal. Under the conditions of this study, there were no statistically significant differences in overall change from baseline for visual grading and TEWL between the experimental product and the marketed reference product for all subjects. Changes from baseline for skin erythema and skin marking were generally small for both products for all subjects as well as for both diabetics and non‐diabetics. There were no serious adverse events (AEs), and no withdrawals due to AEs. Overall comfort assessments of size and fit were ‘just right,’ and skin comfort in the leg, waist and crotch areas were ‘comfortable’ or ‘very comfortable’ for both products. Conclusions In‐use 14‐day testing demonstrated few statistical differences between experimental product with unique odor neutralizing technology and currently marketed product for skin assessments and comfort. Both products were comfortable and well‐tolerated.
