Speech Enhancement Based on A New Architecture of Wasserstein Generative Adversarial Networks (2018)

Most conventional speech enhancement methods work poorly at low SNRs. And the speech enhancement method based on generative adversarial network (SEGAN) gets lower speech quality though it has lots of parameters in its generator. To solve these problems, we propose a speech enhancement method based on a new architecture of Wasserstein generative adversarial network (SEWGAN), whose generator network and discriminator network are structured on the basis of fully convolutional neural networks (FCNNs) and deep neural networks (DNNs) respectively. In the paper, multiple noise and different signal-noise ratios (SNRs) are used to train the proposed method for improving its generalization capability. Experimental results show that the proposed method outperforms SEGAN and minimum mean square error estimators based on magnitude-squared spectrum (MMSE-MSS) in terms of both short-time objective intelligibility (STOI) and perceptual evaluation of speech quality (PESQ). As expected, the work also demonstrates the proposed method has strong generalization capability in a real-world scenario.
Proteolytic Digestion Patterns of “Soluble”and “Detergent‐Soluble”Bovine Caudate Nucleus Acetylcholinesterases (1985)

The structures of purified "soluble" and "detergent-soluble" bovine caudate nucleus acetylcholinesterases were compared by peptide mapping on polyacrylamide gels. The digestion products generated from the two acetylcholinesterases on proteolysis by a given protease (Staphylococcus aureus V8 protease, alpha-chymotrypsin, or papain) are remarkably similar as judged from the electrophoretic band patterns. We conclude that the "soluble" and "detergent-soluble" acetylcholinesterases from bovine caudate nucleus share a common evolutionary origin.
Spiral multi-phase CT in evaluating resectability of pancreatic carcinoma. (2002)

Spiral multi-phase CT is superior in revealing the involvement of peripancreatic vessels, the invasion of the neighboring organs, the size, shape and range of carcinoma, and the metastasis of liver and lymph node. The predictability of resection is obviously increased for patients with pancreatic carcinoma.
The regulatory regions of the rice tungro bacilliform virus promoter and interacting nuclear factors in rice (<i>Oryza sativa</i> L.) (1995)

The Rice Tungro Bacilliform Virus (RTBV) promoter confers phloem-specific gene expression in transgenic rice plants. A series of promoter deletion mutants were fused with the Escherichia coli beta-glucuronidase A (uidA) reporter gene and introduced into transgenic rice plants. The RTBV promoter confers substantially stronger expression in shoots than in roots. A fragment of the promoter comprising nucleotides -164 to +45 relative to the transcriptional start site contains sufficient information for phloem-specific gene expression. Within this region, nucleotides -164 to -43 were essential for promoter function since deletion of this fragment dramatically reduced promoter activity. Gel-retardation assays identified two groups of rice nuclear factors (RNFG1 and RNFG2) that bind to the -164 to +45 promoter fragment. Competition and DNasel footprinting experiments indicated that RNFG1 bound to nucleotides -3 to +8 (Box I) while RNFG2 bound to nucleotides -53 to -39 (Box II). Interactions between the two groups of factors were observed. In addition, we found differences in the binding of nuclear factors from shoots versus from roots, in agreement with the different activities of the promoter in these two organs. It is proposed that binding of RNFG1 and RNFG2 between nucleotides -164 to +45 is essential for the tissue-specific expression of this promoter.
Design and Commissioning of a New Thruster Assisted Mooring System (TAMS) For Global Producer III (2007)

The paper describes the new Thruster Assisted Mooring System (TAMS) designed and installed on the Global Producer III turret-moored Floating Production Storage and Offload FPSO. The system is the first of a new generation of controllers, which include enhanced hardware, a new Human Machine Interface (HMI) and a new, robust control system specifically for moored vessels. Also included is an Advisory Prediction System (APS), based on the same hardware and HMI. The control system has been redesigned to remove the reliance on measured anchor tensions, which have proved to be notoriously unreliable, and to minimize uneconomical thruster activity. It includes new modes of operation, which reflect the desired usage and complement the mooring system, rather than fighting it. Anchor-break detection logic enables anchor breaks to be reliably identified.
BVPN (Broadband Virtual Private Network): a flexible, high-speed, enterprise network architecture (2002)

The implementation of ATM and Intelligent Network (IN) in communications networks is coming. ATM, the technology for transmitting and switching multimedia information over broadband network, requires a highly functional system for controlling highspeed communications services. IN, the technology for providing advanced network services, requires highspeed transmission of service control signals. Although both technologies have evolved independently, it is now time for their integration to create flexible enterprise and public networks for high-speed wide-area communications. By applying both ATM and IN technologies to Virtual Private Network (VPN) concept, a flexible Broadband Virtual Private Network (BVPN) architecture can be created which serves the enterprise WAN needs as well as migrates BISDN into the public network. We show that ATM shared buffer memory switch is very effective for BVPN traffic shaping. Then, software architecture is proposed to adapt to the BVPN services. Finally, there is a description of the broadband intelligent network testbed system based on Distributed processing Environment (DPE).
Robust and high quality video watermarking with the use of temporal redundancy (2001)

In this paper, we present a new video watermarking technique, which utilize the characteristic of temporal redundancy of video sequence to improve the quality and robustness of the watermarked sequence. The proposed watermarking technique can be combined with many existing 2D image-watermarking algorithm to take advantage of their robustness against various attacks. For every watermark bit (formula available in paper), the pseudo random sequence (formula available in paper) is added to the mid-band coefficients of a block and the complementary sequence, (formula available in paper) is added to the same block in another frame of the insertion pair. To retrieve the embedded watermark bit, the block in the first frame is subtracted by the same block of the second frame, resulting in a watermark with double the magnitude (formula available in paper). Since adjacent video frames are highly correlated and the DCT coefficients are almost the same (especially in non-moving regions), the subtraction of the block pair also cancels out most of the interfering DCT coefficients originated from the host signal, such that the interference to the watermark signal from the host signal is minimized during detection. Experiment shows that the probability of receiving an error bit can be reduced or the picture quality is improved while maintaining the same probability of error.
Solid‐State Chemistry of Cyanine‐Type Dyes and the Effect of Two Novel Counterions on Their Crystal Properties (1985)

Abstract Organic dyes undergo a variety of solid‐state chemical processes, including intra‐ and intermolecular reactions, gas‐solid reactions, and polymorphic transformations. The properties of dye solids are markedly affected by this chemistry. This paper reviews solid state dye chemistry from the literature and reports in detail the chemistry of two novel cyanine dye salts whose properties are controlled by the nature of their counterions. In cyanine‐oxonol salts, the oxonol counterion is a large planar dye which forms crystalline dye aggregates with cyanine ions. There is a multiplicity of polymorphic forms of these mixed dyes reflecting multiple favorable dye aggregate geometries. The cyanine‐borate salts undergo intermolecular solid‐state reactions. In either large single crystals or dispersions of the latter salts in polymer binders, alkyl transfer from the anion to the chromophore can be induced thermally or photochemically.
Two Phase Oxidation of Aldehydes with Chromic Acid (1971)

The possibility of the two-phase oxidation of an aldehyde to carboxylic acid was studied. Thus the ether solutions of representative aldehydes (2.0M) were treated with 1.5 mole equivalent of chromic acid solution (1.0M) for 30 minutes at room temperature. Of the ten aldehydes tested,m butanal, benzaldehyde, tolualdehyde, o-, m-, p-nitrobenzaldehyde and cinnamaldehyde could be oxidized conveniently to the corresponding carboxylic acid giving an 80-90% yield. But furfural gave only a 30% yield of furoic acid and the oxidation of salicylaldehyde was unsuccessful.
Sterile Anesthesia Breathing Circuits Do Not Prevent Postoperative Pulmonary Infection (1981)

In a prospective, randomized trial, the effectiveness of sterile anesthesia breathing circuits having bacterial filters in decreasing the incidence of postoperative pulmonary infection was evaluated. Two hundred ninety-three patients undergoing major surgical procedures were assigned randomly to receive anesthetics through a sterile, disposable circuit having a bacterial filter, or a reusable circuit that had been washed and dried after previous use. The two groups were well matched for age, sex, type of surgical procedure, type of anesthetic, and history of smoking or obstructive lung disease. A physician observer, who was unaware of these assignments, reviewed the patients' post-operative status for evidence of pulmonary infection. The over-all rate of infection was 3.5 per cent; no significant difference in the rates of infection occurred between the two groups. Five (3.6 per cent) of the 138 patients anesthetized with sterile circuits had postoperative respiratory infection, compared with four (2.6 per cent) of the 155 patients anesthetized with unsterile circuits. In both groups, maximum postoperative temperature, white-blood-cell count, and the lowest values for arterial oxygen tension were similar. The authors therefore conclude that when simple hygienic measures are followed, the routine use of sterile anesthesia breathing circuits with bacterial filters does not decrease the risk of postoperative infection.
Signal processing algorithms for hyperspectral remote sensing of chemical plumes (2008)

Long-wave infrared (LWIR) hyperspectral imaging sensors are widely used for the detection and identification of released chemical agents in many civilian and military applications. Current hyperspectral system capabilities are limited by variation in the background clutter as opposed to the physics of photon detection. Hence, the development of statistical models for background clutter and optimum signal processing algorithms that exploit these models are essential for the design of practical systems that satisfy user's requirements. This paper describes a signal processing system for the detection and identification of released chemical agents developed at MIT Lincoln Laboratory. We discuss the underlying signal models, key detection and identification algorithms, and some areas where the signal processing community could contribute.
병원의 서비스가 고객의 행동의도에 미치는 영향 -지각된 CSR활동의 조절적 역할을 중심으로- (2016)

There have been conducted researches on how Corporate Social Responsibility (CSR) creates strategic value in the global market consistently. Preceding researches on CSR insist that CSR activities do not only have positive effects on corporate image and brand awareness, but also have high level of relativeness with the performance of a corporation. This study examines the influence of core and supplementary hospital services on revisits and recommendations. This study also indicates that the perceived level of CSR activity of a hospital has considerable effects on clients’ revisits and recommendations, and on their attitude toward a brand.The findings of the study are as follows: 1) the core services and the value-enhancing services provided by a hospital have positive effects on customers`` attitude toward a brand and revisit and recommendation intention 2)The perceived level of CSR activity has positive effects on customers`` revisit and recommendation intention 3) The effects of CSR activities of a hospital on customers`` satisfaction, attitude toward the brand, and revisit and recommendation intention depend on whether information on the CSR activity was presented. Further consistency of CSR activities is required to be carried out since the perceived CSR activities of a hospital effects trust in and attitude toward a brand, and recommendation leads to positive evaluations in the long run such as profit increase.
Effect of probenecid on dyphylline elimination (1983)

Dyphylline is a methylxanthine bronchodilator with such a short a biologic t 1/2 that development of practical dosing regimens has been difficult. Because its rapid renal elimination suggests active secretion, the effect of 1 gm probenecid on single-dose elimination kinetics of dyphylline was determined. Twelve subjects (six male, six female) participated in a crossover design. Subjects were their own controls and received dyphylline, 20 mg/kg orally, alone and after probenecid. The dyphylline t 1/2 increased from 2.57 +/- 0.45 to 4.88 +/- 1.2 hr, whereas the elimination rate constant decreased from 0.276 +/- 0.056 to 0.150 +/- 0.037 hr-1 after probenecid. There was no significant change in the dyphylline apparent volume of distribution. Dyphylline total body clearance fell from 173 +/- 20 to 95 +/- 12 ml/kg . hr. The combined use of these drugs may lead to a practical dyphylline dosage schedule in aminophylline-hypersensitive patients or those incapacitated by theophylline gastrointestinal side effects.

Human Cytomegalovirus Up-Regulates the Phosphatidylinositol 3-Kinase (PI3-K) Pathway: Inhibition of PI3-K Activity Inhibits Viral Replication and Virus-Induced Signaling (2001)

Infection of quiescent fibroblasts with human cytomegalovirus (HCMV) was found to cause a rapid activation of cellular phosphatidylinositol 3-kinase (PI3-K). Maximum PI3-K activation occurred from 15 to 30 min postinfection. This activation was transient, and by 2 h postinfection (hpi), PI3-K activity had declined to preinfection levels. However, at 4 hpi, a second tier of PI3-K activation was detected, and PI3-K activity remained elevated relative to that of mock-infected cells for the remainder of infection. The cellular kinases Akt and p70S6K and the transcription factor NF-kappaB were activated in a PI3-K-dependent manner at similar times following HCMV infection. Analysis using UV-irradiated virus indicated that no viral protein synthesis was necessary for the first phase of PI3-K activation, but viral protein expression was required for the second tier of PI3-K activation. Treatment of infected fibroblasts with LY294002, a potent and specific inhibitor of PI3-K kinase activity, caused a 4-log decrease in viral titers. LY294002 did not inhibit viral entry, but it did decrease viral immediate-early gene expression. In addition, the protein levels of two viral early genes required for DNA replication, UL84 and UL44, were significantly lower in the presence of LY294002. Furthermore, viral DNA replication was strongly inhibited by LY294002 treatment. This inhibition of viral DNA replication could be reversed by adding back the products of PI3-K activity (PI-3,4-P(2) and PI-3,4,5-P(3)), demonstrating that the effect of LY294002 on the viral life cycle was specifically due to the inhibition of PI3-K activity. These results are the first to suggest that PI3-K mediates HCMV-induced activation of host cell mitogenic pathways. They also provide strong evidence that PI3-K activation is important for initiation of viral DNA replication and completion of the viral lytic life cycle.
Neutralizing antibodies protect mice against Venezuelan equine encephalitis virus aerosol challenge (2022)

Venezuelan equine encephalitis virus (VEEV) remains a risk for epidemic emergence or use as an aerosolized bioweapon. To develop possible countermeasures, we isolated VEEV-specific neutralizing monoclonal antibodies (mAbs) from mice and a human immunized with attenuated VEEV strains. Functional assays and epitope mapping established that potently inhibitory anti-VEEV mAbs bind distinct antigenic sites in the A or B domains of the E2 glycoprotein and block multiple steps in the viral replication cycle including attachment, fusion, and egress. A 3.2-Å cryo-electron microscopy reconstruction of VEEV virus-like particles bound by a human Fab suggests that antibody engagement of the B domain may result in cross-linking of neighboring spikes to prevent conformational requirements for viral fusion. Prophylaxis or postexposure therapy with these mAbs protected mice against lethal aerosol challenge with VEEV. Our study defines functional and structural mechanisms of mAb protection and suggests that multiple antigenic determinants on VEEV can be targeted for vaccine or antibody-based therapeutic development.
Ink‐jet‐printable phosphorescent organic light‐emitting‐diode devices (2008)

Abstract— A novel method for the fabrication of ink‐jet‐printed organic light‐emitting‐diode devices is discussed. Unlike previously reported solution‐processed OLED devices, the emissive layer of OLED devices reported here does not contain polymeric materials. The emission of the ink‐jet‐printed P 2 OLED (IJ‐P 2 OLED) device is demonstrated for the first time. It shows good color and uniform emission although it uses small‐molecule solution. Ink‐jet‐printed green P 2 OLED devices possess a high luminous efficiency of 22 cd/A at 2000 cd/m 2 and is based on phosphorescent emission. The latest solution‐processed phosphorescent OLED performance by spin‐coating is disclosed. The red P 2 OLED exhibits a projected LT50 of >53,000 hours with a luminous efficiency of 9 cd/A at 500 cd/m 2 . The green P 2 OLED shows a projected LT50 of >52,000 hours with a luminous efficiency of 35 cd/A at 1000 cd/m 2 . Also discussed is a newly developed sky‐blue P 2 OLED with a projected LT50 of >3000 hour and a luminous efficiency of 18 cd/A at 500 cd/m 2 .

An international database for pesticide risk assessments and management (2016)

Despite a changing world in terms of data sharing, availability, and transparency, there are still major resource issues associated with collating datasets that will satisfy the requirements of comprehensive pesticide risk assessments, especially those undertaken at a regional or national scale. In 1996, a long-term project was initiated to begin collating and formatting pesticide data to eventually create a free-to-all repository of data that would provide a comprehensive transparent, harmonized, and managed extensive dataset for all types of pesticide risk assessments. Over the last 20 years, this database has been keeping pace with improving risk assessments, their associated data requirements, and the needs and expectations of database end users. In 2007, the Pesticide Properties DataBase (PPDB) was launched as a free-to-access website. Currently, the PPDB holds data for almost 2300 pesticide active substances and over 700 metabolites. For each substance around 300 parameters are stored, covering human health, environmental quality, and biodiversity risk assessments. With the approach of the twentieth anniversary of the database, this article seeks to elucidate the current data model, data sources, its validation, and quality control processes and describes a number of existing risk assessment applications that depend upon it.
Interleukin-2 inhalation therapy temporarily induces asthma-like airway inflammation. (2007)
