Enhancing the 3rd order nonlinear optical response of integrated micro-ring resonators with graphene oxide 2D films (2021)

Abstract Layered two-dimensional (2D) graphene oxide (GO) films are integrated with micro-ring resonators (MRRs) to experimentally demonstrate enhanced nonlinear optics in the form of four-wave mixing (FWM). Both uniformly coated and patterned GO films are integrated on CMOS-compatible doped silica MRRs using a large-area, transfer-free, layer-by-layer GO coating method together with photolithography and lift-off processes, yielding precise control of the film thickness, placement, and coating length. The high Kerr nonlinearity and low loss of the GO films combined with the strong light-matter interaction within the MRRs results in a significant improvement in the FWM efficiency in the hybrid MRRs. Detailed FWM measurements are performed at different pump powers and resonant wavelengths for the uniformly coated MRRs with 1 − 5 layers of GO as well as the patterned devices with 10 − 50 layers of GO. The experimental results show good agreement with theory, achieving up to ~ 7.6-dB enhancement in the FWM conversion efficiency (CE) for an MRR uniformly coated with 1 layer of GO and ~ 10.3-dB for a patterned device with 50 layers of GO. By fitting the measured CE as a function of pump power for devices with different numbers of GO layers, we also extract the dependence of GO’s third-order nonlinearity on layer number and pump power, revealing interesting physical insights about the evolution of the layered GO films from 2D monolayers to quasi bulk-like behavior. These results confirm the high nonlinear optical performance of integrated photonic resonators incorporated with 2D layered GO films.
Perception of Welsh vowel contrasts by Welsh-Spanish bilinguals in Argentina (2017)

This study investigates the perception of Welsh vowel contrasts by Welsh-Spanish bilinguals. A two-alternative forced choice perception task elicited subjects’ reliance on vowel tenseness and duration in the identification of ambiguous Welsh vowels. Results demonstrate no effect of order of acquisition on speakers’ reliance on duration (over vowel quality) as a cue to vowel identity in Welsh. This supports past work demonstrating that speakers of a language which lacks a given contrast perceptually rely on the most salient phonetic dimension of that contrast in an L2. Results were also atypical: language dominance outweighed a predicted age of acquisition effect on speakers adaptation to L2 phonetic cues.
The reaction of bromo- and iodo-phosphoranes with unactivated coarse grain manganese metal powder to yield [MnI2(phosphine)2] and [{MnX2(phosphine)}n](X = Br or I) by insertion of Mn into the P–X bond. The crystal structure of [MnI2(PPh3)2] (1993)

The novel reaction of crude manganese metal powder with dibromo- and diiodo-phosphoranes, R3PX2, has been studied. Reaction of the phosphoranes R3PI2(R = phenyl or substituted aryl) with manganese allows insertion of the metal into P–X bonds and gives the monomeric tetrahedral complexes [MnI2(PR3)2] and MnI2. However, reaction of R3PX2(R3= mixed aryl/alkyl, trialkyl; X = Br or I) with manganese, whilst once again proceeding via insertion into P–X bonds, now leads to the quantitative isolation of the polymeric complexes [{MnX2(PR3)}n], thus illustrating the subtle nature of these reactions. Examples of both types of complex have been crystallographically characterised and represent rare examples of such. There is some evidence that where R3= Ph2Me an equilibrium exists and both types of complex, [MnI2(PPh2Me)2] and [{MnI2(PPh2Me)}n] can be detected from the same reaction.
Ultra thin PoP top package using compression mold: Its warpage control (2011)

Package on Package (PoP) is one of the increasingly used high density package solution for package stacking technology in various device manufacturing applications. Normally PoP configurations use a top package with a stacked memory packaging system connected to a bottom logic packaging system via solder joint. To guarantee the assembly yield and reliability of the solder joint between the top package and bottom package, mechanical compliance between these two packages is crucial during package stacking. The industry is constantly working toward reducing the total stack height and current road maps point toward a thinner total stack Z height of PoP configuration. It is necessary to reduce the package height by reducing the mold cap thickness as well as reduce the mold cap clearance, the distance between the top silicon die to the mold top. However, it is one of the increasing challenges to reduce top package thickness maintaining its low warpage behaviors during the reflow process and to avoid bonding wire exposure after laser mark process due to thin mold cap clearance. In this paper, we used the compression mold process to fabricate PoP top package test vehicle with different mold cap thickness at around 80 um mold cap clearance on 14×14 package size, and investigated the effects of various molding compound materials and substrate material properties on PoP top package warpage behaviors during solder reflow process. The substrates are all 100 um thickness and 2 layer structure. As the mold cap thickness gets thinner, the warpage variation during reflow process gets larger. The material property of key component in top PoP package plays a crucial role in warpage performance. The thermo-mechanical properties of molding compounds after compression molding process and substrate materials are very important and mainly determine the warpage level of the top package at room temperature and the warpage behaviors during the reflow profile for the board level assembly with bottom package. The compression mold compound material properties and substrate core materials were optimized to improve the ultra thin PoP top package. The findings and results provide a guideline of the material selection for warpage control in the PoP top package to improve the PoP assembly yield and reliability.

A Deep Neural Network to identify foreshocks in real time (2016)

Foreshock events provide valuable insight to predict imminent major earthquakes. However, it is difficult to identify them in real time. In this paper, I propose an algorithm based on deep learning to instantaneously classify a seismic waveform as a foreshock, mainshock or an aftershock event achieving a high accuracy of 99% in classification. As a result, this is by far the most reliable method to predict major earthquakes that are preceded by foreshocks. In addition, I discuss methods to create an earthquake dataset that is compatible with deep networks.
Protein substitute for children and adults with phenylketonuria (2005)

No conclusions could be made about the short- or long-term use of protein substitute in phenylketonuria due to the lack of adequate trial data. A randomised controlled trial is needed to investigate the use of protein substitute in phenylketonuria. Until further evidence is available current practice in the use of protein substitute should continue to be observed and monitored with care.

Décision dans les systèmes cyber-physiques et humains : application à l’élevage de précision (2019)

L'élevage de précision a pour objectif d'améliorer la productivité des exploitations agricoles et s'appuie sur un ensemble d'équipements technologiques qui produisent des données qu'il convient de collecter, stocker et analyser et qui concernent chaque animal et son environnement. Cette nouvelle façon de gérer une exploitation agricole constitue un domaine d'application privilégié pour les travaux de recherche sur les Cyber-Physical and Human Systems. La problématique explorée dans cet article part du constat que les éleveurs font face à une augmentation considérable de la quantité de données qu'ils doivent traiter. Il est alors nécessaire de mettre au point un système d'aide à la décision prenant en compte les données « temps réel » mais aussi la connaissance experte pour permettre aux éleveurs d'agir au mieux. Dans cette communication, nous mettons en évidence les défis spécifiques au développement d'un système d'aide à la décision pour le domaine de l'élevage de précision et nous présentons une méthodologie pour l'implémenter dans ce contexte.
Highly Flexible Solar Sheets With High Specific Power for Stratospheric Flight Applications (2020)

MicroLink has developed highly flexible solar sheets that exhibit high specific power and are suitable for stratospheric flight applications. Here we present reliability test data as well as actual stratospheric flight data of these solar sheets. Data from the 24-hour high-altitude balloon flight that was performed in September 2019 out of Baltic, SD at an altitude of 19km showed peak power output of 421W/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> of MicroLink's panel at an operating temperature of 24°C. This translates into a specific power of the solar sheets of 1,668 W/kg including top sheet and adhesive layers.
Pressure and temperature tuning of an external cavity InGaAsP laser diode (2008)

We demonstrate wide-range tuning of an 830 nm InGaAsP laser diode by pressure and temperature combined with tuning by external grating. Pressure tuning (up to 11 kbar) yields the wavelength range of 70 nm limited by the increase of the threshold current. Temperature tuning from room temperature down to 90 K yields the wavelength range of 56 nm. The reliability of the lasers subjected to pressure or temperature cycles seems to be mainly related to mounting-induced strains, i.e. the choice of proper submount is crucial. The tuning range achieved with external grating decreases at high pressure (and at low temperature).

Interstitial Granulomatous Dermatitis-A Case Report Associated with Rheumatoid Arthritis (2005)

Interstitial granulomatous dermatitis is a rare entity first described by Ackerman et al. in 1993. We described a 57-year-old female, with a long-standing history of rheumatoid arthritis, presenting with symmetric violaceous to erythematous indurated papules and nodules on her buttock and medial thighs arranging in an arciform fashion for more than three months. Pathologically, it showed palisaded granulomas containing degenerated collagen, predominantly lymphohistiocytic infiltration with scattered eosinophils leading to dermal fibrosis. Some atypical histiocytes were also present. Combining the clinical and pathological pictures, interstitial granulomatous dermatitis was diagnosed.
Mass spectrometry analysis {\sl Mycoplasma hyorhinis} lipoprotein p37 by protease cleavage (2006)

p37 is a membrane lipoprotein of Mycoplasma hyorhinis. To understand its function in mammalian ceils, we analyzed the post-translation modification of membrane lipoprotein p37 and its biological functions in mammalian cells. With matrix-assisted laser desorption ionization-time of flight-mass spectrometry and N- terminal amino acid sequencing, we found when p37 was expressed in COS-7 ceils, there were three kinds of the proteins with different mass weights 47 644,46 105 and 43 984, respectively. The first 21 amino acids at the N-terminal and about 18-26 amino acids at the C-terminal were cleaved off by peptidase or protease. This procedure may be necessary for p37 to be mature and functional in mammalian cells.
The analysis of smokestack samples for dioxins by gas chromatography/mass spectrometry and gas chromatography/tandem mass spectrometry (1990)

Abstract A CONCEPT 1 SQ hybrid mass spectrometer has been used to show the potential of high resolution mass spectrometry and hybrid tandem mass spectrometry (MS/MS) for dioxin analysis. The usual method chosen for gas chromatography/mass spectrometry (GC/MS) determination of polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) is selected‐ion monitoring (SIM) at high resolution, the high resolution imparting a degree of specificity to the analysis. An alternative technique is to use low resolution (1000) gas chromatography/tandem mass spectrometry on a hybrid mass spectrometer, where the specificity of MS/MS is utilized. Data are presented illustrating the potential of both techniques from a single instrument, the CONCEPT 1 SQ.
General Correction Mechanisms for Weakening or Reinforcing Belief Functions (2006)

The discounting operation is a well known operation on belief functions, which has proved to be useful in many applications. However, the discounting operation only allows one to weaken a source, whereas it is sometimes useful to strengthen it when it is deemed to be too cautious. For that purpose, the de-discounting operation was introduced as the inverse operation of the discounting operation by Denoeux and Smets. From another point of view, Zhu and Basir introduced an extension of the classical discounting operation by allowing the discount rate to be out of the range [0,1]. This operation performs a discounting or a de-discounting of a belief function. A new interpretation of this scheme is presented in this paper. A more general form of reinforcement process, as well as a parameterized family of transformations encompassing all previous schemes, are also introduced
Simple parameters estimation and precise over-voltage simulation in long cable connected drives (2016)

Over-voltage at the motor side when supplied by Voltage Source Inverter (VSI) using long cables could cause winding failure and it is known to be source of electromagnetic disturbances, both radiated and conducted. In this paper, the over-voltage prediction for such drives in industrial environment has been investigated. Minor run time execution and precise simulations are the main paper targets. A novel cable model has been considered for motor over-voltage and converter over-current estimation. Two different measurement methodologies for the model parameters have been introduced too. The first methodology is accurate and could measure both the proposed parameters needed by the application and the filter parameters needed to mitigate these problems. The second is simpler and could only estimate the filters parameters. Comparison between experimental and simulation results are presented in the paper to confirm the proposed methods.
Time Domain Analogue to Digital Conversion in a Digital Pixel Sensor Array (2005)

This paper presents a digital pixel sensor array, in which the photodiode sensor, the analogue to digital conversion circuitry, and an 8-bit memory are combined in the 45 /spl mu/m/spl times/45 /spl mu/m pixel, yielding a 12% fill factor. The conversion is performed by measuring the time taken for the photodiode, operating in direct integration mode, to discharge from its reset voltage to a reference voltage. An on chip control circuit is used to compensate for the non-linear relationship between the photocurrent and the integration time. The 64/spl times/64 pixel array is manufactured using a standard 0.35 /spl mu/m, five metal, digital CMOS process.
Uncovering Biological Network Function via Graphlet Degree Signatures (2008)

Proteins are essential macromolecules of life and thus understanding their function is of great importance. The number of functionally unclassified proteins is large even for simple and well studied organisms such as baker's yeast. Methods for determining protein function have shifted their focus from targeting specific proteins based solely on sequence homology to analyses of the entire proteome based on protein-protein interaction (PPI) networks. Since proteins aggregate to perform a certain function, analyzing structural properties of PPI networks may provide useful clues about the biological function of individual proteins, protein complexes they participate in, and even larger subcellular machines. We design a sensitive graph theoretic method for comparing local structures of node neighborhoods that demonstrates that in PPI networks, biological function of a node and its local network structure are closely related. The method groups topologically similar proteins under this measure in a PPI network and shows that these protein groups belong to the same protein complexes, perform the same biological functions, are localized in the same subcellular compartments, and have the same tissue expressions. Moreover, we apply our technique on a proteome-scale network data and infer biological function of yet unclassified proteins demonstrating that our method can provide valuable guidelines for future experimental research.
Kruppel-Like Factor 4 Is Essential for Inflammatory Monocyte Differentiation In Vivo (2008)

Several members of the Kruppel-like factor (KLF) family of transcription factors play important roles in differentiation, survival, and trafficking of blood and immune cell types. We demonstrate in this study that hematopoietic cells from KLF4(-/-) fetal livers (FL) contained normal numbers of functional hematopoietic progenitor cells, were radioprotective, and performed as well as KLF4(+/+) cells in competitive repopulation assays. However, hematopoietic "KLF4(-/-) chimeras" generated by transplantation of KLF4(-/-) fetal livers cells into lethally irradiated wild-type mice completely lacked circulating inflammatory (CD115(+)Gr1(+)) monocytes, and had reduced numbers of resident (CD115(+)Gr1(-)) monocytes. Although the numbers and function of peritoneal macrophages were normal in KLF4(-/-) chimeras, bone marrow monocytic cells from KLF4(-/-) chimeras expressed lower levels of key trafficking molecules and were more apoptotic. Thus, our in vivo loss-of-function studies demonstrate that KLF4, previously shown to mediate proinflammatory signaling in human macrophages in vitro, is essential for differentiation of mouse inflammatory monocytes, and is involved in the differentiation of resident monocytes. In addition, inducible expression of KLF4 in the HL60 human acute myeloid leukemia cell line stimulated monocytic differentiation and enhanced 12-O-tetradecanoylphorbol 13-acetate induced macrophage differentiation, but blocked all-trans-retinoic acid induced granulocytic differentiation of HL60 cells. The inflammation-selective effects of loss-of-KLF4 and the gain-of-KLF4-induced monocytic differentiation in HL60 cells identify KLF4 as a key regulator of monocytic differentiation and a potential target for translational immune modulation.
한국인에서 오타모반의 임상 양상 (2010)

목적: 오타 모반 환자를 대상으로 병변의 임상양상에 대해 알아보고자 하였다. 대상과 방법: 2005년부터 2010년까지 본원 안과를 방문하여 세극등 현미경으로 오타 모반이 진단된 76명 81안에 대해서 전안부 사진, 정면 사진, 의무기록을 후향적으로 분석하였다. 결과: 모반의 발생 혹은 발견 나이는 평균 8개월이었으며, 범위는 평균 253도로 특별히 호발하는 위치 없이 대부분 여러 사분면에 걸쳐 있었다. 모반이 옅은 군에서 연령이 어렸으며, 모반이 눈 구석 공막을 침범하는 경우는 없었으나, 윤부에 색소 침착이 있었던 경우는 86.5%에 해당하였다. 결막 색소 침착이 61.7%에서 동반되었고, 결막 색소 침착이 있는 군에서 없는 군보다 모반 범위가 유의하게 넓었다. 홍채 색소 침착은 98.7%에서 동반되어 오타 모반과의 연관성이 매우 높았다. 결론: 한국인에서 오타모반은 위치, 범위, 색깔 등에 있어 다양한 양상을 보인다. 공막 외 색소 침착 여부는 모반 범위와 관련있고, 홍채 색소 침착은 매우 흔하게 관찰되어 진단적 가치가 있었다. 연령이 적은 환자에서는 모반의 색깔이 옅어 청색 공막과 유사해 골형성 부전증과의 감별이 필요하겠다.
