High-speed photonic device technologies in optical fiber connected millimeter-wave radar system for foreign object debris detection on runways (2014)

Precise imaging of obstacles and foreign-object debris (FOD) is one of the most important security technologies for avoiding trouble in advance. Recently, we have focused on an optical fiber connected millimeter-wave radar system using a radio over fiver (RoF) technique for effectively detecting FOD over the large area of an airport runway. In this paper, we introduce high-speed photonic devices such as a W-band frequency modulated continuous-wave (FM-CW) signal generator, a highly-sensitive quantum dot (QD) photodetector, and a QD optical frequency comb laser (QD-CML) with harmonically optical pulsation. It is expected that these advanced photonic device technologies will become potential candidates for use in the RoF technique to realize the optical fiber connected millimeter-wave radar system.
Urinary cytokines/chemokines pattern in patients with painful bone metastases undergoing external beam radiotherapy experiencing pain flare (2016)

Patients who experience pain flare appear to have a different pattern in urinary cytokine/chemokine levels than patients without pain flare. A larger study is required to confirm the possible role of cytokines/chemokines in predisposition to and/or the cause of pain flare following radiation to painful bone metastases.
Verfügbarkeitsorientierte Instandhaltung (2007)

Kurzfassung Die Instandhaltung ist maßgeblich für die Gewährleistung einer be-darfsgerechten Verfügbarkeit verantwortlich – das haben viele Unternehmen erkannt. Allerdings gelingt es nur wenigen, dies auch konsequent und effizient umzusetzen. In dem vom BMBF geförderten Forschungs- und Entwicklungsprojekt „Verstand“ wird daher ein verfügbarkeitsorientierter Instandhaltungsansatz erarbeitet, der Unternehmen hilft, die wesentlichen Stellhebel zur Aufrechterhaltung und Steigerung der Verfügbarkeit optimal zu nutzen. In technologischer Hinsicht wird ein Quasistandstandard geschaffen, der die Kompatibilität zwischen den einzelnen Systemen der Maschinen- und Unternehmenswelt herstellt, Maschinen- und Prozessdaten der Produktionsanlagen erfasst und an ERP- und/oder IPS-Systeme für Steuerungs-, Auswertungs- und Kontrollaufgaben weitergibt.
High-Performance Interaction-Based Simulation of Gut Immunopathologies with ENteric Immunity Simulator (ENISI) (2012)

Here we present the ENteric Immunity Simulator (ENISI), a modeling system for the inflammatory and regulatory immune pathways triggered by microbe-immune cell interactions in the gut. With ENISI, immunologists and infectious disease experts can test and generate hypotheses for enteric disease pathology and propose interventions through experimental infection of an in silico gut. ENISI is an agent based simulator, in which individual cells move through the simulated tissues, and engage in context-dependent interactions with the other cells with which they are in contact. The scale of ENISI is unprecedented in this domain, with the ability to simulate $10^7$ cells for 250 simulated days on 576 cores in one and a half hours, with the potential to scale to even larger hardware and problem sizes. In this paper we describe the ENISI simulator for modeling mucosal immune responses to gastrointestinal pathogens. We then demonstrate the utility of ENISI by recreating an experimental infection of a mouse with Helicobacter pylori 26695. The results identify specific processes by which bacterial virulence factors do and do not contribute to pathogenesis associated with H. pylori strain 26695. These modeling results inform general intervention strategies by indicating immunomodulatory mechanisms such as those used in inflammatory bowel disease may be more appropriate therapeutically than directly targeting specific microbial populations through vaccination or by using antimicrobials.
Physics of scintillator nonproportionality (2011)

Scintillator nonproportionality is a key mechanism by which the energy resolution is degraded in gamma spectroscopy. Herein, we survey the results obtained for a number of inorganic scintillating materials, including alkali and multivalent halides, fluorides, simple oxides, silicates, and a tungstate. The results are interpreted in the context of a model that accounts for carrier attraction by the Onsager mechanism and exciton-exciton annihilation by the Birks model. We then utilize the theory of Landau fluctuations in combination with the fitted experimental nonproportionality curves to deduce the predicted value of the resolution degradation.
Toward Controllable Molecular Shuttles (1997)

Abstract A number of nanometer‐scale molecular assemblies, based on rotaxane‐type structures, have been synthesized by means of a template‐directed strategy from simple building blocks that, on account of the molecular recognition arising from the noncovalent interactions between them, are able to self‐assemble into potential molecular abacuses. In all the cases investigated, the π‐electron‐deficient tetracationic cyclophane cyclobis(paraquat‐ p ‐phenylene) is constrained mechanically around a dumbbell‐shaped component consisting of a linear polyether chain intercepted by at least two, if not three, π‐electron‐rich units and terminated at each end by blocking groups or stoppers. The development of an approach toward constructing these molecular abacuses, in which the tetracationic cyclophane is able to shuttle back and forth with respect to the dumbbell‐shaped component, begins with the self‐assembly of a [2]rotaxane consisting of two hydroquinone rings symmetrically positioned within a polyether chain terminated by triisopropylsilyl ether blocking groups. In this first so‐called molecular shuttle, the tetracationic cyclophane oscillates in a degenerate fashion between the two π‐electron‐rich hydroquinone rings. Replacement of one of the hydroquinone rings—or the insertion of another π‐electron‐rich ring system between the two hydroquinine rings—introduces the possibility of translational isomerism, a phenomenon that arises because of the different relative positions and populations of the tetracationic cyclophane with respect to the π‐donor sites on the dumbbell‐shaped component. In two subsequent [2]rotaxanes, one of the hydroquinone rings in the dumbbell‐shaped component is replaced, first by a p ‐xylyl and then by an indole unit. Finally, a tetrathiafulvalene (TTF) unit is positioned between two hydroquinone rings in the dumbbell‐shaped component. Spectroscopic and electrochemical investigations carried out on these first‐generation molecular shuttles show that they could be developed as molecular switches.
Preparation of Monodisperse LiCoO2 Hollow Particles by Membrane Emulsification Using Anodic Porous Alumina (2018)

Abstract Monodisperse LiCoO2 hollow particles were prepared by membrane emulsification using ordered anodic porous alumina. An aqueous solution containing metal salts and a chelating agent was used as the dispersed phase for the emulsification. The uniform-sized emulsion droplets formed by membrane emulsification were solidified on a filter membrane by drying in air. LiCoO2 hollow particles were formed by calcination of the precursor particles. The obtained monodisperse particles are expected to be suitable for use as an active cathode material for Li-ion batteries because of their large surface area and uniform size.
Rocca: An Efficient AES-based Encryption Scheme for Beyond 5G (2021)

In this paper, we present an AES-based authenticated-encryption with associated-data scheme called Rocca, with the purpose to reach the requirements on the speed and security in 6G systems. To achieve ultra-fast software implementations, the basic design strategy is to take full advantage of the AES-NI and SIMD instructions as that of the AEGIS family and Tiaoxin-346. Although Jean and Nikolić have generalized the way to construct efficient round functions using only one round of AES (aesenc) and 128-bit XOR operation and have found several efficient candidates, there still seems to exist potential to further improve it regarding speed and state size. In order to minimize the critical path of one round, we remove the case of applying both aesenc and XOR in a cascade way for one round. By introducing a cost-free block permutation in the round function, we are able to search for candidates in a larger space without sacrificing the performance. Consequently, we obtain more efficient constructions with a smaller state size than candidates by Jean and Nikolić. Based on the newly-discovered round function, we carefully design the corresponding AEAD scheme with 256-bit security by taking several reported attacks on the AEGIS family and Tiaxion-346 into account. Our AEAD scheme can reach 138Gbps which is 4 times faster than the AEAD scheme of SNOW-V. Rocca is also much faster than other efficient schemes with 256-bit key length, e.g. AEGIS-256 and AES-256-GCM. As far as we know, Rocca is the first dedicated cryptographic algorithm targeting 6 systems, i.e., 256-bit key length and the speed of more than 100 Gbps.
Combination therapy with oral tacrolimus (FK506) and azathioprine or 6-mercaptopurine for treatment-refractory Crohn's disease perianal fistulae (2007)

Our aim was to report the clinical experience with combination treatment using tacrolimus and either azathioprine (AZA) or 6-mercaptopurine (6MP) in patients with Crohn's disease (CD) perianal fistulae. The medical records of all patients with Crohn's disease perianal fistulae seen at the Mayo Clinic from 1996-1998 who were treated with tacrolimus were reviewed. Clinical response was classified as: complete response, partial response, and nonresponse. Eleven patients were treated with oral tacrolimus for a mean duration of 22 weeks. The initial oral dose of tacrolimus ranged from 0.15 to 0.31 mg/kg/day. Azathioprine or 6MP was continued in combination with tacrolimus in seven patients and initiated simultaneously with tacrolimus in four patients. All patients improved clinically, seven had a complete response, and four had a partial response. The mean time to initial improvement was 2.4 weeks, and the mean time to complete response was 12.2 weeks. The most frequent adverse events were nausea, paresthesias, nephrotoxicity, and tremor. Patients with nephrotoxicity had a significantly higher mean initial tacrolimus dose (0.31 mg/kg/day) compared with patients who did not have nephrotoxicity (0.25 mg/kg/day) (p = 0.035); however, there was not a statistically significant association between the starting dose or mean blood level and clinical response. Combination therapy with oral tacrolimus and AZA or 6MP may be effective treatment for CD perianal fistulae. Higher initial tacrolimus doses increase the risk of nephrotoxicity without improving clinical response.
Optimization of Cascade Integer Resolution with Three Civil GPS Frequencies (2000)

In the near future, there will be two more civil GPS signals in addition to the current one at the L 1 frequency (1575.42 MHz). The second civil signal will be broadcast at the L2 frequency (1227.60 MHz), and the third civil signal will be broadcast at the recently-selected Lc frequency (I 176.45 MHz). With three civil frequencies, a user can generate three beat frequency signals. The LI and L2 carrier frequencies are processed to create the Widelane (WL) with
wavelength of 86 centimeters. The combination of the L 1 and Lc carrier frequencies yields the second beat frequency with 75 centimeters in wavelength (Medium Lane, ML).
The combination of the L2 and Lc carrier frequencies yields the third beat frequency with 5.9 meters in wave-length (Extra Widelane, EWL).
In earlier research [8], an instantaneous geometry-free carrier-phase DGPS integer ambiguity resolution technique was developed utilizing the multiple available beat frequencies. This technique, known as Cascade Integer Resolution (CIR), resolves the integer ambiguities successively
from the longest to the shortest beat wavelength. The performance of CIR was examined in the earlier study, and it was shown that CIR can be used to resolved the Lc integer ambiguity with probability of wrong integer resolution of IE-4 up to 2.4 kilometers from a reference station. It can also resolve the WL integer ambiguity up to 22 kilometers, and the EWL integer ambiguity beyond that, with the same
probability of incorrect integer resolution.
Performance degradation of the CIR over distance mainly
comes from the spatial decorrelation of ionospheric error
(residual differential troposphere error is eliminated by the
geometry-free CIR process). This paper focuses on recent
improvements to CIR performance to extend service
volume and reduce the probability of incorrect integer resolution. First, effect of decrease in measurement error on performance of the CIR is examined. Then, the spatial gradient of the residual differential ionosphere error, which was assumed to have a fixed standard deviation of 2 parts per million in the earlier research, is estimated by using measurements from two different user locations. Estimation of ionospheric spatial decorrelation is integrated into
the CIR process. With these enhancements, performance of the CIR increased. With the probability of incorrect integer ambiguity resolution of IE-4, the optimized CIR can resolve the Lc integer up to 4 km (increases of 2.4 km) and the WL integer up to 40 km (increase of 22 km).
Decision analysis in nuclear medicine. (1999)

This review focuses primarily on the methodology involved in properly reviewing the literature for performing a meta-analysis and on methods for performing a formal decision analysis using decision trees. Issues related to performing a detailed metaanalysis with consideration of particular issues, including publication bias, verification bias and patient spectrum, are addressed. The importance of collecting conventional measures of test performance (e.g., sensitivity and specificity) and of changes in patient management to model the cost-effectiveness of a management algorithm is detailed. With greater utilization of the techniques discussed in this review, nuclear medicine researchers should be well prepared to compete for the limited resources available in the current health care environment. Furthermore, nuclear medicine physicians will be better prepared to best serve their patients by using only those studies with a proven role in improving patient management.
QSAR for anti-HIV activity of HEPT derivatives (2002)

QSARs were derived for 103 analogues of 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT), a potent inhibitor of the HIV-1 reverse transcriptase (RT). The activity of these compounds was investigated by means of multiple linear regression (MLR) and artificial neural network (ANN) techniques. Considering the relevant descriptors obtained from the MLR, a correlation coefficient of 0.92 (n = 95) was obtained with a 4-5-1 ANN model. The contribution of each descriptor to the structure-activity relationships was evaluated. The results showed that the anti-HIV activity of HEPT derivatives was strongly dependent on hydrophobic character and also steric factors of substituents.
Fractional Fourier transform features for speech recognition (2004)

In this paper a novel speech signal representation method is presented. The proposed method is based on the fractional Fourier transform (FrFT), which is a generalization of the classical Fourier transform (FT). Even though we use FrFT in feature extraction for speech recognition, it can very well be used in other areas such as enhancement, verification, and synthesis, where parametric representation of speech is needed. Experimental results conducted on the Aurora 2 database show significant improvements over MFCC at high SNR conditions.
Role of microRNAs involved in plant response to nitrogen and phosphorous limiting conditions (2015)

Plant microRNAs (miRNAs) are a class of small non-coding RNAs which target and regulate the expression of genes involved in several growth, development, and metabolism processes. Recent researches have shown involvement of miRNAs in the regulation of uptake and utilization of nitrogen (N) and phosphorus (P) and more importantly for plant adaptation to N and P limitation conditions by modifications in plant growth, phenology, and architecture and production of secondary metabolites. Developing strategies that allow for the higher efficiency of using both N and P fertilizers in crop production is important for economic and environmental benefits. Improved crop varieties with better adaptation to N and P limiting conditions could be a key approach to achieve this effectively. Furthermore, understanding on the interactions between N and P uptake and use and their regulation is important for the maintenance of nutrient homeostasis in plants. This review describes the possible functions of different miRNAs and their cross-talk relevant to the plant adaptive responses to N and P limiting conditions. In addition, a comprehensive understanding of these processes at molecular level and importance of biological adaptation for improved N and P use efficiency is discussed.
An Efficient In-Memory Computing Architecture for Image Enhancement in AI Applications (2022)

Random Spray Retinex (RSR) is an effective image enhancement algorithm due to its effectiveness in improving image quality. However, the algorithm computing complexity and the required hardware resources and memory accesses hampered its deployment in many applications scenarios, for instance in IoT systems with limited hardware resources. With the rise of Artificial Intelligence (AI), the use of image enhancement has become essential to improve the performance for many emerging applications. In this paper, we propose the use of the RSR as a pre-processing filter before the task of semantic segmentation of low-quality urban road scenes. Using the publicly available Cityscapes dataset, we compare the performance of a pre-trained deep semantic segmentation network on dark noisy images and on RSR pre-processed images. Our findings confirm the effectiveness of RSR in improving segmentation accuracy. In addition, to address the computation complexity and suitability to edge devices, we propose a novel efficient implementation of the RSR using resistive random access memory (RRAM) technology. The architecture provides highly parallel analog in-memory computing (IMC) capabilities. A detailed, efficient and low latency implementation of the RSR using RRAM-CMOS technology is described. The design is verified using SPICE simulations with measured data from fabricated RRAM and 65nm CMOS technologies. The approach provided here represents an important step towards low-complexity and real-time hardware-friendly architecture and design for Retinex algorithms for edge devices.

Synthesis and Spectroscopic Characterization of Silver(I) Complexes of Selenones (2003)

Silver(I) complexes of selenones, [LAgNO3] and [AgL2]NO3 (where L is imidazolidine-2-selenone or diazinane-2-selenone and their derivatives) have been prepared and characterized by elemental analysis, IR and NMR (1H, 13C and 107Ag) spectroscopy. An upfield shift in the C=Se resonance of selenones in 13C NMR and a downfield shift in N-H resonance in 1H NMR are consistent with selenium coordination to silver(I). In 107Ag NMR, the AgNO3signal is deshielded by 450-650 ppm on coordination to selenones. Greater upfield shifts in 13C NMR were observed for [LAgNO3] compared to [AgL2]NO3complexes, whereas the opposite trend was observed for 1H and107Ag NMR chemical shifts.
Ubiquitous Detection of Gram-Positive Bacteria with Bioorthogonal Magnetofluorescent Nanoparticles (2011)

The ability to rapidly diagnose gram-positive pathogenic bacteria would have far reaching biomedical and technological applications. Here we describe the bioorthogonal modification of small molecule antibiotics (vancomycin and daptomycin), which bind to the cell wall of gram-positive bacteria. The bound antibiotics conjugates can be reacted orthogonally with tetrazine-modified nanoparticles, via an almost instantaneous cycloaddition, which subsequently renders the bacteria detectable by optical or magnetic sensing. We show that this approach is specific, selective, fast and biocompatible. Furthermore, it can be adapted to the detection of intracellular pathogens. Importantly, this strategy enables detection of entire classes of bacteria, a feat that is difficult to achieve using current antibody approaches. Compared to covalent nanoparticle conjugates, our bioorthogonal method demonstrated 1-2 orders of magnitude greater sensitivity. This bioorthogonal labeling method could ultimately be applied to a variety of other small molecules with specificity for infectious pathogens, enabling their detection and diagnosis.
Ultrafast carrier dynamics in single-walled carbon nanotubes probed by femtosecond spectroscopy (2004)

We present studies of the ultrafast carrier dynamics in single-walled carbon nanotubes using femtosecond fluorescence and transient absorption techniques. We find that the dynamics are dependent on excitation intensity and the electronic transitions initially excited.

Resist Parameter Extraction from Line-and-Space Patterns of Chemically Amplified Resist for Extreme Ultraviolet Lithography (2010)

The development of extreme ultraviolet (EUV) lithography has progressed owing to worldwide effort. As the development status of EUV lithography approaches the requirements for the high-volume production of semiconductor devices with a minimum line width of 22 nm, the extraction of resist parameters becomes increasingly important from the viewpoints of the accurate evaluation of resist materials for resist screening and the accurate process simulation for process and mask designs. In this study, we demonstrated that resist parameters (namely, quencher concentration, acid diffusion constant, proportionality constant of line edge roughness, and dissolution point) can be extracted from the scanning electron microscopy (SEM) images of patterned resists without the knowledge on the details of resist contents using two types of latest EUV resist.
