Enzymatic hydrolysis of heterocyclic nitriles (1992)

Abstract Chemoselective hydrolysis of heterocyclic nitriles can be achieved by an easy to use immobilized biocatalyst prepared from Rhodococcus sp . Pyrimidine‐2‐carbonitrile ( 2a ) and 3‐chloropyridazine‐4‐carbonitrile ( 4a ) were converted into the corresponding amides while from 2‐ethoxycarbonyl‐4‐pyridinecarbonitrile ( 1a ), 6‐methylpyridazine‐3‐carbonitrile ( 3a ), 3‐chloropyridazine‐4‐carbonitrile ( 4a ), 3‐ethoxycarbonyl‐4,5‐dihydroisoxazole‐5‐carbonitrile ( 8a ), indole‐3‐carbonitrile ( 9a ) and indole‐3‐ylacetonitrile ( 10a ) the acids were formed.
Sugar content of carrot roots as influenced by the culture technology. (2012)

The amount of sugar in carrots has an obvious influence upon the perception of the sweettaste and can also hide the bitter taste. In the experiment conducted in 2011, the amount of sugar in theroots of the carrots was taken into consideration for the varieties studied, Flakker and Nantes,depending on the time of sowing and the fertilizer used. The values obtained for the varieties studiedregistered sugar content between 8.70 and 10.93 mg/100 g.s.p.
Enhanced driver safety with advanced vision systems (2018)

With increasing information diverting attention and longer commutes causing greater fatigue, safe operation of vehicles is a growing concern. The concept of workload management in the operation of vehicles is driving the automotive industry to address these issues. This paper discusses two primary technologies that will realize the objectives of workload management. Driver State Monitoring (DSM) and Gesture Recognition (GS) systems are being implemented into production vehicles on a rapid and urgent path. The impact of these technologies on driver fatigue and safety will be demonstrated. Subsystem architecture and the integration of DSM/GS subsystems into vehicle architecture will be illustrated. Sensor technologies, image recognition/processing, and decision logic will be discussed. Finally, the state of these technologies, current limitations, and development paths will be discussed.
Enhancement and Quenching of Single Molecule Fluorescence near a Gold Nanoparticle (2005)

We present a theoretical and experimental study of single molecule fluorescence in the proximity of a laser-irradiated metal nanoparticle. As the molecule is approached towards the particle the fluorescence rate increases but then drops rapidly for distances smaller than 10nm. This fluorescence quenching phenomenon is not accounted for by the dipole approximation and hence more rigorous theoretical models need to be applied.
Functional and Structural Characterization of Neutralizing Epitopes of Measles Virus Hemagglutinin Protein (2012)

Effective vaccination programs have dramatically reduced the number of measles-related deaths globally. Although all the available data suggest that measles eradication is biologically feasible, a structural and biochemical basis for the single serotype nature of measles virus (MV) remains to be provided. The hemagglutinin (H) protein, which binds to two discrete proteinaceous receptors, is the major neutralizing target. Monoclonal antibodies (MAbs) recognizing distinct epitopes on the H protein were characterized using recombinant MVs encoding the H gene from different MV genotypes. The effects of various mutations on neutralization by MAbs and virus fitness were also analyzed, identifying the location of five epitopes on the H protein structure. Our data in the present study demonstrated that the H protein of MV possesses at least two conserved effective neutralizing epitopes. One, which is a previously recognized epitope, is located near the receptor-binding site (RBS), and thus MAbs that recognize this epitope blocked the receptor binding of the H protein, whereas the other epitope is located at the position distant from the RBS. Thus, a MAb that recognizes this epitope did not inhibit the receptor binding of the H protein, rather interfered with the hemagglutinin-fusion (H-F) interaction. This epitope was suggested to play a key role for formation of a higher order of an H-F protein oligomeric structure. Our data also identified one nonconserved effective neutralizing epitope. The epitope has been masked by an N-linked sugar modification in some genotype MV strains. These data would contribute to our understanding of the antigenicity of MV and support the global elimination program of measles.
Motif Extraction with Indicative Events for System Call Sequence Classification (2007)

Various approaches have been proposed to extract patterns from system call sequences invoked by applications to better model their behaviors. They use fixed-length or variable-length patterns to represent the sequences. However, these techniques are all based on mathematical rules and do not consider the underlying mechanism of the program execution. In this paper, we propose a method that extracts the motifs - subroutines conserved across sequences - in an efficient way by using the semantic call graph model. We focus on two cases: one is intrusion detection; the other is automatic problem diagnosis, and show that the presences of our defined motifs are highly discriminative features to represent different application behaviors. This is in agreement with the idea that taking these motifs to be the building blocks of program execution. Using these features, we can achieve higher detection rate while maintaining lower false positive.
Securing the manufacturing environment using biometrics (2005)

Over the past decade, there has been substantial growth in global business, of which the manufacturing industry plays a large part. This, accompanied by an increase in intelligent manufacturing equipment, increased connectivity of equipment and software both internally within a company, and with external partners has led to an increase in the probability of attacks and threats to these systems. Combine this with the current events and the additional requirements of governmental regulation, and several businesses in advanced manufacturing have to increase both physical and logical security. This paper outlines a unique application of biometrics and computer integrated manufacturing systems as part of providing an applied solution to solving security problems for manufacturing and control systems, and adhering to government regulations related to the manufacturing industry.
Exploring Turn-taking Cues in Multi-party Human-robot Discussions about Objects (2015)

In this paper, we present a dialog system that was exhibited at the Swedish National Museum of Science and Technology. Two visitors at a time could play a collaborative card sorting game together with the robot head Furhat, where the three players discuss the solution together. The cards are shown on a touch table between the players, thus constituting a target for joint attention. We describe how the system was implemented in order to manage turn-taking and attention to users and objects in the shared physical space. We also discuss how multi-modal redundancy (from speech, card movements and head pose) is exploited to maintain meaningful discussions, given that the system has to process conversational speech from both children and adults in a noisy environment. Finally, we present an analysis of 373 interactions, where we investigate the robustness of the system, to what extent the system's attention can shape the users' turn-taking behaviour, and how the system can produce multi-modal turn-taking signals (filled pauses, facial gestures, breath and gaze) to deal with processing delays in the system.
An S/X-band CMOS power amplifier using a transformer-based reconfigurable output matching network (2017)

A dual-band power amplifier (PA) with an integrated reconfigurable transformer is presented. The PA operating in the S/X-band is fully integrated using a 0.18-μm RF CMOS process. The switchable transformer is designed by tuning its primary winding and a shunt capacitor at 50Ω load with passive efficiency more than 62%/67% for S/X-band. The measurement results show saturated output power (P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SAT</sub> ) of 24.3/21.2 dBm with peak drain efficiency (DE) of 34.8%/12.2% at 3.1/8.0 GHz, respectively. The 1-dB bandwidth is 0.7/1.25 GHz (2.8-3.5/7.5-8.75 GHz) for the S/X-band. This amplifier with the proposed transformer is suitable for use in an integrated dual-band high-resolution radar transceiver.
Interleukin-22 (2012)

This is the first report investigating immune modulation by T-cell-derived IL-22 in liver injury caused by warm ischemia and reperfusion. Treatment with IL-22 protein may represent a novel therapeutic strategy to prevent liver IRI in transplant recipients.
Hepatoprotective and toxicological evaluation of hepatomed, an ayurvedic drug. (1995)

Hepatoprotective effect of Hepatomed (an ayurvedic drug containing water extract of 6 medicinal plants) has been studied on cumene hydroperoxide (CHP) induced lipid peroxidation and reduced glutathione content in rat liver homogenate. In vitro experiments show significant reduction in the level of malondialdehyde (MDA) induced by 1.5 mM cumene hydroperoxide(CHP). Glutathione content was almost maintained to normal in drug treated rats. Oral treatment of drug up to 3 ml/100 g body weight for 15 days did not show any rise in serum GOT and GPT. On similar doses, significant choleratic effect was observed without any adverse histological changes after 4 days treatment. The results suggest that 'Hepatomed' is a strong hepatoprotective ayurvedic medicine with no detectable adverse effects.
Quasiparticle energies for cubic BN, BP, and BAs (1991)

Electronic excitation energies at the high-symmetry points \ensuremath{\Gamma}, X, and L are obtained for zinc-blende-structure BN, BP, and BAs in the GW approximation using a model dielectric function. A model for the static screening matrix makes use of the ab initio ground-state charge density and either experimental values or empirical estimates for ${\mathrm{\ensuremath{\epsilon}}}_{\mathrm{\ensuremath{\infty}}}$, the electronic contribution to the macroscopic dielectric constant. Wave functions from an ab initio local-density-approximation calculation with norm-conserving pseudopotentials are employed along with the self-consistent quasiparticle spectrum to obtain the energy-dependent one-particle Green function G. The minimum band gaps are found to be 6.3, 1.9, and 1.6 eV for BN, BP, and BAs, respectively, in close agreement with existing measurements of 6.1 and 2.0 eV for BN and BP, respectively. The BN direct band gap is predicted to be 11.4 eV versus the experimental value of 14.5 eV, and the BP direct band gap is predicted to be 4.4 eV versus 5.0 eV from experiment.
Ensemble deep neural networks for domain-specific Image Recognition (2016)

The dog breeds recognition is the topic of the MSR Image Recognition Challenge (IRC) @ IEEE ICME 2016. In order to sufficiently train the deep neural networks (DNNs) used in this domain-specific image recognition task, we append two high quality public dog datasets and one noisy dog pictures dataset crawled from web to the Clickture-Dog dataset provided by the Challenge. At the preprocessing stage, we enhance the edge of images to emphasize the boundaries of the dogs in image. At the same stage, we adopt the multi-scale training strategy on both the original images and images with edge enhancement. Therefore, we have total four different preprocessing configurations. Finally, we integrate 12 base-DNN sub-models and soft-max posteriors into a committee machine. We implement our recognition algorithm and convert it to Microsoft cloud service. Our team, named as NFS2016, get the third place in this challenge.
An oxidative DNA “damage” and repair mechanism localized in the VEGF promoter is important for hypoxia-induced VEGF mRNA expression (2015)

In hypoxia, mitochondria-generated reactive oxygen species not only stimulate accumulation of the transcriptional regulator of hypoxic gene expression, hypoxia inducible factor-1 (Hif-1), but also cause oxidative base modifications in hypoxic response elements (HREs) of hypoxia-inducible genes. When the hypoxia-induced base modifications are suppressed, Hif-1 fails to associate with the HRE of the VEGF promoter, and VEGF mRNA accumulation is blunted. The mechanism linking base modifications to transcription is unknown. Here we determined whether recruitment of base excision DNA repair (BER) enzymes in response to hypoxia-induced promoter modifications was required for transcription complex assembly and VEGF mRNA expression. Using chromatin immunoprecipitation analyses in pulmonary artery endothelial cells, we found that hypoxia-mediated formation of the base oxidation product 8-oxoguanine (8-oxoG) in VEGF HREs was temporally associated with binding of Hif-1α and the BER enzymes 8-oxoguanine glycosylase 1 (Ogg1) and redox effector factor-1 (Ref-1)/apurinic/apyrimidinic endonuclease 1 (Ape1) and introduction of DNA strand breaks. Hif-1α colocalized with HRE sequences harboring Ref-1/Ape1, but not Ogg1. Inhibition of BER by small interfering RNA-mediated reduction in Ogg1 augmented hypoxia-induced 8-oxoG accumulation and attenuated Hif-1α and Ref-1/Ape1 binding to VEGF HRE sequences and blunted VEGF mRNA expression. Chromatin immunoprecipitation-sequence analysis of 8-oxoG distribution in hypoxic pulmonary artery endothelial cells showed that most of the oxidized base was localized to promoters with virtually no overlap between normoxic and hypoxic data sets. Transcription of genes whose promoters lost 8-oxoG during hypoxia was reduced, while those gaining 8-oxoG was elevated. Collectively, these findings suggest that the BER pathway links hypoxia-induced introduction of oxidative DNA modifications in promoters of hypoxia-inducible genes to transcriptional activation.
Comparative Study on Carrier Phase Estimation Methods in Dispersion-Unmanaged Optical Transmission Systems (2016)

The comparative study on three carrier phase estimation (CPE) methods, involving a one-tap normalized leastmean-square algorithm, a block-wise average algorithm, and a\nViterbi-Viterbi algorithm has been carried out in the long-haul high-speed dispersion-unmanaged coherent optical transmission systems. The close-form predictions for bit-error-rate behaviors in these CPE methods have been analyzed by considering both the laser phase noise and the equalization enhanced phase noise.

Efficient Bi-Directional Digital Communication Scheme for Isolated Switch Mode Power Converters (2012)

An efficient high-speed bi-directional data transmission scheme for isolated AC-DC and DC-DC switched mode power converters is presented. The bi-directional scheme supports fast, efficient and reliable transmission of digitally encoded data across the isolation barrier and enables primary side control, allowing effective start-up and a simple interface to system controllers. Another key feature is that the bi-directional communication is independent of coupler gain and degradation and only the minimum number of couplers is required. The digital interface can also be used to transmit auxiliary signals between both sides. For test purposes, the scheme has been implemented on FPGAs and verified using a custom-built SMPC board.
Unicompartmental replacement and high tibial osteotomy for osteoarthritis of the knee. A comparative study after 5-10 years' follow-up (1986)

We have made a retrospective comparison between the results of 49 high tibial osteotomies and 42 unicompartmental replacement arthroplasties performed for the treatment of osteoarthritis of the knee, assessed 5 to 10 years after operation. The type of operation depended on the policy of the consultant responsible for treatment but analysis of the pre-operative findings showed that the two groups were sufficiently similar for direct comparison between them. In the replacement group, 32 (76%) were good, 4 were fair, 3 were poor and 3 had been revised. In the osteotomy group 21 (43%) were good, 11 were fair, 7 were poor and 10 had been revised. It was concluded that, in this series, the results of unicompartmental replacement were significantly better and that this group had shown no sign of late deterioration.
Soundtrack: An Auditory Interface for Blind Users (Abstract Only) (1989)

Throughout the history of human-computer interface development one aspect has remained constant: output from computers has been almost entirely visual. A continued and increasing reliance on visual communication has had a disadvantageous effect on users who have visual disabilities. A visual interface is of no use to a user who is completely blind: communication must use one of the other senses, and hearing is an obvious candidate. A number of human-computer interfaces have been developed and adapted into an auditory form based on the use of synthetic speech. However, for modern interfaces which use more complex displays, synthetic speech is not sufficient. One attempt to adapt such a mouse-based interface into an auditory form based on musical tones and synthetic speech is described. This project involved the development of a word processor called Soundtrack with an auditory interface. Evaluation of this application suggests that the approach is viable, but that it was difficult to use, and there are significant research questions still to be addressed.

A Distributed Proxy Architecture for Service Discovery in Peer-to-Peer Networks (2006)

In this work we present a service discovery system that supports flexible queries using partial keywords and wildcards. It is built upon a Chord network and it guarantees that any existing data that match a query is found. The main feature of this service is to use a proxy server layer with a mechanism for data distribution that reduces the number of nodes involved in the searching process.
A New Type of Digital Filter for Data Transmission (1975)

A digital filter is introduced consisting of a transversal part and a simple recursive network. The coefficients of the transversal part are equal to integer powers of two or zero; thus complicated multipliers are avoided and instead a simple routing circuit is used. Use of several types of the recursive network makes the filter applicable in different frequency ranges. The coefficients of the transversal part can be interpreted as differences of successive values of the impulse response of the filter. It is shown that this difference routing digital filter (DRDF) is especially suited for application in data transmission.
Depolarization fields in thin ferroelectric films (1973)

A mechanism is proposed to explain depolarization phenomena that have been observed in thin ferroelectric films and related multilayer devices. It is shown that, for a short-circuited electrode-ferroelectric structure, incomplete compensation of the ferroelectric polarization charge results when the center of gravity of this charge and the free compensation charge are not coincident. Depolarization fields in the ferroelectric arising from such incomplete compensations are estimated. A simple switching calculation shows such fields to be of sufficient strength to account for the initial polarization decay rate observed in Pb0.92Bi0.07La0.01 (Fe0.405Nb0.325Zr0.27)O3 films. The results of measurements involving changes in film thickness, electron concentration in the electrodes, and contact materials will be discussed and shown to be consistent with the mechanism proposed.
