Weakly Supervised Cross-Lingual Named Entity Recognition via Effective Annotation and Representation Projection (2017)

The state-of-the-art named entity recognition (NER) systems are supervised machine learning models that require large amounts of manually annotated data to achieve high accuracy. However, annotating NER data by human is expensive and time-consuming, and can be quite difficult for a new language. In this paper, we present two weakly supervised approaches for cross-lingual NER with no human annotation in a target language. The first approach is to create automatically labeled NER data for a target language via annotation projection on comparable corpora, where we develop a heuristic scheme that effectively selects goodquality projection-labeled data from noisy data. The second approach is to project distributed representations of words (word embeddings) from a target language to a source language, so that the sourcelanguage NER system can be applied to the target language without re-training. We also design two co-decoding schemes that effectively combine the outputs of the two projection-based approaches. We evaluate the performance of the proposed approaches on both in-house and open NER data for several target languages. The results show that the combined systems outperform three other weakly supervised approaches on the CoNLL data.
Band Type Wearable Device's RF Configuration and Bent Microstrip Patch Antenna (2015)

본 논문에서는 WCDMA2100 이동통신망을 사용하는 밴드형 wearable device에 적합한 bent 마이크로스트립 패치 안테나와 이를 적용하기 위한 RF configuration을 제안하였다. 제안된 안테나는 WCDMA2100 송수신 주파수 대역을 분리한 RF configuration을 사용하여 WCDMA 송신대역에서만 동작하도록 설계되었고, 후면의 도체(ground)로 인해 인체의 영향을 적게 받는다. 제안된 안테나는 flat 및 bent할 경우 모두 최대 이득은 5.3 dBi 이상, -6 dB 반사손실 대역폭은 20 MHz 이상을 가지고 전자파 인체 흡수율 시뮬레이션 <TEX>$SAR_{1g}$</TEX> 0.7 [W/kg] 이하를 갖는다. 제안된 안테나는 사람의 손목이나 팔에 착용하는 밴드형 wearable device에 적합하게 사용될 수 있다. In this paper, a bent microstrip patch antenna, which is suitable for band-type wearable devices and RF configuration, to be used in the WCDMA2100 mobile network is proposed. The proposed antenna using RF configuration which is consisted of separated Tx and Rx frequency band is designed to operate or function in WCDMA2100 Tx frequency band only and it is not strongly affected by the human body because of the conductor at the bottom side. At both flat case and bent case, the proposed antenna's maximum gain satisfies at least 5.3 dBi, and its -6 dB return loss bandwidth is wider than 20 MHz. The simulated surface absorption rate(<TEX>$SAR_{1g}$</TEX>) result is under 0.7 [W/kg]. The proposed antenna suits in band-type wearable devices which is worn on wrists or arms.
Adaptive Repair of Compressed Video Signals using Local Objective Metrics of Blocking Artifacts (2007)

The paper presents a new objective metrics of blocking artifacts visibility in MPEG compressed video sequences. The metric estimates a local visibility of the block grid by analyzing the discontinuity of a pixel intensity trend across the block edge and by comparing it against pixel activities within blocks. Application of the local blockiness metrics for adaptive control of low-pass filtering provides significant reduction of coding artifacts without blurring of image details. The results of our experiments show the high efficiency of the proposed approach.

Flying-height adjustment of a magnetic head slider with a piezoelectric micro-actuator (2003)

The current design of magnetic disk head sliders needs two extra margins in flying height design: one for manufacturing tolerance and one for environmental variations. To reduce these margins, we have developed an adjustable flying height slider. This slider carries a piezoelectric microactuator and its flying height can be controlled. After simulating the piezoelectric deflection and flying characteristics, we designed an air-bearing surface for the slider and fabricated it by silicon microelectromechanical systems processing. Several of the fabrication problems previously reported were solved, and the slider's change in the flying height as an electric voltage was applied to the microactuator was optically observed. The observed stroke of this flying height adjustment, 6 nm/15 V, was less than the simulated stroke because of contact between the head and the disk, but it is still large enough to reduce the two current flying-height margins.

III-nitride optoelectronic devices are discussed. Ultraviolet detectors and visible emitters towards terahertz intersubband devices are reported. Demonstration of single photon detection efficiencies of 33% in the ultraviolet regime, intersubband energy levels as low as in the mid-infrared regime, and GaN-based resonant tunneling diodes with negative resistance of 67 Ω are demonstrated.
A 5-GHz 108-Mb/s 2x2 MIMO transceiver RFIC with fully integrated 20.5-dBm P1dB power amplifiers in 90-nm CMOS (2006)

Multiple antenna transceivers combined with MIMO signal processing offer the potential for increased data rates and/or range in wireless systems. This paper presents a fully integrated 5-GHz 2x2 MIMO WLAN transceiver RFIC implemented in 90-nm CMOS. The paper identifies the key MIMO integration issues and proposes techniques to optimize MIMO performance. It is shown that crosstalk between the multiple transceivers residing on the same die can degrade MIMO performance and has to be carefully minimized, especially when power amplifiers are integrated on-die. A shared LO generation and distribution network is designed to maximize MIMO phase noise immunity without introducing undesired crosstalk. The fabricated MIMO receiver achieves a sensitivity of -63 dBm while receiving 108 Mb/s in MIMO spatial multiplexing mode in the presence of a 25-ns Rayleigh fading channel. The sensitivity of a single receiver in the presence of AWGN noise is -76 dBm. Linearized 3.3-V 5-GHz power amplifiers with P 1dB = 20.5 dBm deliver an average power of +13 / + 16 dBm each, in MIMO/SISO modes respectively (EVM = -27/ - 25 dB). The measured performance demonstrates the effectiveness of the isolation techniques employed. The system in a package includes an 18 mm 2 die and microstrip front-end matching networks implemented on a flip-chip package.
Divide and conquer evolutionary TSP solution for vehicle path planning (2008)

The problem of robotic area coverage is applicable to many domains, such as search, agriculture, cleaning, and machine tooling. The robotic area coverage task is concerned with moving a vehicle with an effector, or sensor, through the task space such that the sensor passes over every point in the space. For covering complex areas, back and forth paths are inadequate. This paper presents a real-time path planning architecture consisting of layers of a clustering method to divide and conquer the problem combined with a two layered, global and local optimization method. This architecture is able to optimize the execution of a series of waypoints for a restricted mobility vehicle, a fixed wing airplane.

Blockade of Platelet GPIIB-IIIA (Integrin αIIbβ3) in Flowing Human Blood Leads to Passivation of Prothrombotic Surfaces (2002)

We examined the impact of platelet activation on platelet adhesion to collagen in flowing human blood. ADP activation of platelets in ex vivo flowing blood resulted in paradoxical inhibition of platelet deposition on collagen. Blockade of fibrinogen binding to platelets by Lamifiban, a competitive antagonist of GPIIb-IIIa (integrin alpha(IIb)beta(3)), reversed this inhibition, leading to a marked increase in integrin alpha(2)beta(1)-dependent platelet adhesion. Analysis of integrin alpha(2)beta(1)-dependent platelet adhesion to collagen indicated that ADP-induced suppression of platelet adhesion is the result of trans-dominant inhibition of integrin alpha(2)beta(1) caused by fibrinogen binding to integrin GPIIb-IIIa. Lamifiban blocked fibrinogen binding, reversing the trans-dominant inhibition of alpha(2)beta(1) dependent adhesion to collagen. The GPIIb-IIIa antagonist resulted in the formation of a non-thrombogenic, passivated surface comprised of an adherent platelet monolayer. This unexpected consequence of blocking fibrinogen binding to GPIIb-IIIa may explain the long-term benefits of short-term GPIIb-IIIa antagonist treatment of Acute Coronary Syndrome patients.
Quality of life of HIV-negative, previously healthy individuals following cryptococcal meningoencephalitis (2021)

The morbidity and mortality of cryptococcal meningoencephalitis (CM) in previously healthy, HIV-negative individuals is increasingly recognized. We administered a healthcare associated quality of life (QOL) survey to the largest longitudinally followed cohort of these patients in the United States. We identified moderate or severe self-reported impairment in at least one QOL domain in 61% of subjects at least one year following diagnosis. Self-reported cognitive impairment was noted in 52% and sleep disturbance was noted in 55%. This is the first comprehensive study of cross-sectional long-term QOL in previously healthy patients following cryptococcal infection.

Introduction of Heteroatom-Based Substituents into 1,4-Dihydropyridines by Means of a Halogen-Mediated, Oxidative Protocol: Diamination, Sulfonylation, Sulfinylation, Bis-Sulfanylation, and Halo-Phosphonylation Processes (2000)

The natural tendency of 1,4-dihydropyridines to undergo "biomimetic" oxidation to afford pyridinium salts can be switched off and, through the use of reagents that interact electrophilically with the enamine moiety present in the heterocyclic system, it is possible to promote alternative oxidations. In this way, efficient regio- and stereocontrolled synthetic methods have been developed that lead to diversely substituted di- and tetrahydropyridines. These include iodoazidation, diamination, bis-sulfonamidation, sulfonylation, sulfinylation, thiocyanation, sulfanylation, bis-sulfanylation, and halo-phosphonylation processes.
Monoclonal Lym-1 Antibody-Dependent Cytolysis by Neutrophils Exposed to Granulocyte-Macrophage Colony-Stimulating Factor: Intervention of FcγRII (CD32), CD11b-CD18 Integrins, and CD66b Glycoproteins (1999)

Murine monoclonal antibody (MoAb) Lym-1 is an IgG2a able to bind HLA-DR variants on malignant B cells and suitable for serotherapeutic approaches in B-lymphoma patients. We have previously shown that Lym-1 can synergize with granulocyte-macrophage colony-stimulating factor (GM-CSF) to trigger neutrophil cytolysis towards Raji cells used as a model of B-lymphoma targets. Here we provide evidence for the intervention of certain neutrophil receptors or surface molecules in this model of cell-mediated lysis. The lysis was completely inhibited by the anti-FcgammaRII MoAb IV.3 and unaffected by the anti-FcgammaRIII MoAb 3G8. This suggests that neutrophil cytolysis involves FcgammaRII without cooperation of this receptor with FcgammaRIII. Moreover, the lysis was inhibited by an anti-CD18 MoAb (MEM48) and by a MoAb specific for carcinoembryonic antigen (CEA)-like and glycophosphatidyl inositol (GPI)-linked glycoproteins (CD66b). Using an immunofluorescence staining procedure, cross-linking of CD66b induced the redistribution of CD11b on neutrophils with distinct areas of CD11b clustering via a process susceptible of inhibition by D-mannose. This is consistent with the ability of CD11b-CD18 and CD66b to undergo lectin-like physical interactions on the neutrophil surface. Such a type of interaction is presumably instrumental for neutrophil cytolytic activity in that the lysis was inhibited by D-mannose and enhanced by the MoAb VIM-12, which mimics the cooperation between CD11b and GPI-anchored molecules by specifically interacting with CD11b lectin-like sites. Therefore, the present results prove the absolute requirement for FcgammaRII in neutrophil GM-CSF/Lym-1-mediated cytolysis and, on the other hand, define the crucial role of CD66b and CD11b/CD18 in the expression of the cell lytic potential.
Comparison of 4-Class and Continuous Fat/Water Methods for Whole-Body, MR-Based PET Attenuation Correction (2013)

The goal of this study was to compare two approaches for MR-based PET patient attenuation correction (AC) in whole-body FDG-PET imaging using a tri-modality PET/CT and MR setup. Sixteen clinical whole-body FDG patients were included in this study. Mean standard uptake values (SUVs) were measured for liver and lung volumes-of-interest for comparison. Maximum SUVs were measured in 18 FDG-avid features in 10 of the patients. The AC methods compared to gold-standard CT-based AC were segmentation of the CT (air, lung, fat, water), MR image segmentation with four tissue classes (air, lung, fat, water), and segmentation with air, lung and a continuous fat/water method. Results show that magnitude differences of the uptake values induced by CT-based image segmentation were similar but lower on average than those found using MR-derived AC methods. The average liver SUV difference as compared to using CTAC was 1.3%, 10.4%, and 5.7% for 4-class segmented CT, 4-class MRAC, and continuous fat/water MRAC methods, respectively. The average FDG-avid feature SUVmax difference was -0.5%, 1.7%, and -1.6% for 4-class segmented CT, 4-class MRAC, and continuous fat/water MRAC methods, respectively. The results demonstrated that both 4-class and continuous fat/water AC methods provided adequate quantitation in the body, and that the continuous fat/water method was within 5.7% on average for SUVmean in liver and 1.6% on average for SUVmax for FDG-avid features.

Epitaxial Silicon Microshell Vacuum-Encapsulated CMOS-Compatible 200 MHz Bulk-Mode Resonator (2009)

This paper shows the first successful combination of dielectrically-transduced 200 MHz resonators with the epi-silicon encapsulation process, and demonstrates a set of important capabilities needed for the construction of CMOS-compatible RF MEMS components. The result shows the resonant frequency of 207 MHz and a quality factor of 6,400. The high fQ (1.2times10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</sup> Hz) makes this encapsulated resonator an excellent candidate for applications in local oscillators and RF spectrum analyzers.
Resolution enhancement in nonlinear interferenceless COACH with point response of subdiffraction limit patterns (2019)

Interferenceless coded aperture correlation holography (I-COACH) is a non-scanning, motionless, incoherent digital holography technique for 3D imaging. The lateral and axial resolutions of I-COACH are equivalent to those of conventional direct imaging with the same numerical aperture. The main component of I-COACH is a coded phase mask (CPM) used as the system aperture. In this study, the CPM has been engineered using a modified Gerchberg-Saxton algorithm to generate a random distribution of subdiffraction spot arrays on the digital camera as a system response to a point source illumination. A library of point object holograms is created to calibrate the system for imaging different lateral sections of a 3D object. An object is placed within the calibrated 3D space and an object hologram is recorded with the same CPM. The various planes of the object are reconstructed by a non-linear cross-correlation between the object hologram and the point object hologram library. A lateral resolution enhancement of about 25% was noted in the case of I-COACH compared to direct imaging.

Escherichia coli thioredoxin: a subunit of bacteriophage T7 DNA polymerase. (1976)

T7 DNA polymerase (DNA nucleotidyltransferase; deoxynucleosidetriphosphate:DNA deoxynucleotidyltransferase, EC 2.7.7.7) is composed of an 84,000 dalton protein specified by the gene 5 of the phage and a 12,000 dalton protein (TsnC protein) specified by the tsnC gene of E. coli [Modrich, P. & Richardson, C. C. (1975) J. Biol. Chem. 250 5515-5522]. Both proteins are necessary for T7 DNA polymerase activity and for the replication of T7 DNA. The TsnC protein is identical to thioredoxin of E. coli by the following criteria: (1) Homogeneous preparations of both proteins have TsnC and thioredoxin activity. (2) Both proteins show similar stability to heat. (3) They have identical mobilities, corresponding to a molecular weight of 12,000, on polyacrylamide gels containing sodium dodecyl sulfate. (4) Their amino-acid compositions are indistinguishabe. (5) Antibody prepared against thioredoxin inhibits TsnC activity. (6) TsnC protein isolated from purified T7 DNA polymerase has thioredoxin activity. In addition, preparations of T7 DNA polymerase itself exhibit thioredoxin activity and are partially inhibited by antibody to thioredoxin.
CARDIOVASCULAR ASPECTS OF EXPERIMENTAL MENINGOCOCCAL SEPSIS IN YOUNG AND OLDER AWAKE PIGLETS (1999)

Severe meningococcal disease is characterized by: a high load of specific endotoxin, capillary leakage and coagulation disorders. We studied the possible age-related differences in global hemodynamic and regional blood flow responses to different dosages (1 and 10 microg/kg body weight) of rough meningococcal endotoxin in young (8 kg) and older piglets (40 kg). Animals were chronically instrumented and studied in the awake state. The response to plasma infusion (30 mL/kg in 30 min) was evaluated after placebo and endotoxin infusion. The clinical picture was similar in all groups. The mortality was 0/8, 3/8,1/8, 4/9 in young-low, young-high, old-low, and old-high dose respectively. Most important findings were that cardiac index (CI) decreased in the young animals after endotoxin infusion, while it was well preserved in the older animals; in the older animals the systemic vascular resistance dropped 20%, while in the younger ones there was no change in resistance. Conductance to the kidneys, intestines, and spleen decreased significantly more in the young animals, while the increase in conductance and flow to the liver was higher in the old animals; subsequent volume loading resulted only partly in a recovery of the hemodynamic parameters, but failed to improve oxygen delivery.
Autoantibodies in autoimmune polyglandular syndrome type I patients react with major brain neurotransmitter systems (2008)

Patients with autoimmune polyglandular syndrome type I (APS1) often display high titers of autoantibodies (autoAbs) directed against aromatic L-amino acid decarboxylase (AADC), tyrosine hydroxylase (TH), tryptophan hydroxylase (TPH), and glutamic acid decarboxylase (GAD). Neurological symptoms, including stiff-man syndrome and cerebellar ataxia, can occur in subjects with high levels of GAD autoAbs, particularly when patient sera can immunohistochemically stain gamma-aminobutyric acid (GABA) neurons. However, it was not known if APS1 sera can also stain major monoamine systems in the brain. Therefore, in this work we applied sera from 17 APS1 patients known to contain autoAbs against AADC, TH, TPH, and/or GAD to rat brain sections and processed the sections according to the sensitive immunohistochemical tyramide signal amplification method. We found that autoAbs in sera from 11 patients were able to stain AADC-containing dopaminergic, serotonergic, and noradrenergic as well as AADC only (D-group) neurons and fibers in the rat brain, in several cases with a remarkably high quality and sensitivity (dilution up to 1:1,000,000); and, since they are human antibodies, they offer a good opportunity for performing multiple-labeling experiments using antibodies from other species. Six APS1 sera also stained GABAergic neuronal circuitries. Similar results were obtained in the mouse and primate brain. Our data demonstrate that many APS1 sera can immunostain the major monoamine and GABA systems in the brain. Only in a few cases, however, there was evidence that these autoAbs can be associated with neurological manifestations in APS1 patients, as, e.g., shown in previous studies in stiff-man syndrome.
Inhibition of caspase activity does not prevent the signaling phase of apoptosis in prostate cancer cells (1999)

Caspase activation may play a role in the downstream effector phase of the apoptotic cascade; however, in this study, caspase inhibition did not prevent the signaling phase of apoptosis induced by two agents with distinct mechanisms of cytotoxicity, TG or 5-FrdU. These results suggest that caspase inhibition by recently described endogenous caspase inhibitors should not lead to development of resistance to TG. A strategy for targeting TG's unique cytotoxicity to metastatic prostate cancer cells is currently under development.
