Distributed Cooperative Communication and Link Prediction in Cloud Robotics (2017)

While deploying large scale heterogeneous robots in a wide geographical area, communicating among robots and robots with a central entity pose a major challenge due to robotic motion, distance and environmental constraints. In a cloud robotics scenario, communication challenges result in computational challenges as the computation is being performed at the cloud. Therefore fog nodes are introduced which shorten the distance between the robots and cloud and reduce the communication challenges. Fog nodes also reduce the computation challenges with extra compute power. However in the above scenario, maintaining continuous communication between the cloud and the robots either directly or via fog nodes is difficult. Therefore we propose a Distributed Cooperative Multi-robots Communication (DCMC) model where Robot to Robot (R2R), Robot to Fog (R2F) and Fog to Cloud (F2C) communications are being realized. Once the DCMC framework is formed, each robot establishes communication paths to maintain a consistent communication with the cloud. Further, due to mobility and environmental condition, maintaining link with a particular robot or a fog node becomes difficult. This requires pre-knowledge of the link quality such that appropriate R2R or R2F communication can be made possible. In a scenario where Global Positioning System (GPS) and continuous scanning of channels are not advisable due to energy or security constraints, we need an accurate link prediction mechanism. In this paper we propose a Collaborative Robotic based Link Prediction (CRLP) mechanism which predicts reliable communication and quantify link quality evolution in R2R and R2F communications without GPS and continuous channel scanning. We have validated our proposed schemes using joint Gazebo/Robot Operating System (ROS), MATLAB and Network Simulator (NS3) based simulations. Our schemes are efficient in terms of energy saving and accurate link prediction.
Oligoclonal Analysis of the Atopic T Cell Response to the Group 1 Allergen of <i>Cynodon dactylon</i> (Bermuda Grass) Pollen: Pre- and Post-Allergen-Specific Immunotherapy (2002)

<i>Background:</i> Bermuda grass pollen (BGP) is an increasingly important seasonal aeroallergen in Australia and other subtropical and temperate regions. BGP shares minimal allergenic cross-reactivity with pollens of rye grass or other Pooideae grasses often used for desensitization regimens in grass pollen allergy. Current allergen immunotherapy is seldom used in asthmatic patients due to IgE-mediated side effects. Since clinically effective immunotherapy is linked with altered allergen-specific T cell response, characterisation of human T cell reactivity to Cyn d 1, the major B cell allergen of BGP, should permit the design of effective and safe immunotherapy for BGP allergy. <i>Methods:</i> Short-term BGP-specific CD4+ T cell lines were established from peripheral blood of 14 BGP-sensitive patients before and after conventional 50% BGP and 50% 7-grass mix subcutaneous specific allergen immunotherapy (SIT). T cell diversity of antigen specificity and function was assessed by proliferation and cytokine production to BGP, Cyn d 1 and Cyn d 1 peptides. <i>Results:</i> Three highly immunogenic regions of Cyn d 1 were identified in 13/14 patients pre-SIT: Cyn d 1 (109–128), (181–209) and (217–241). The SIT regimen was clinically efficacious. Following SIT, decreased proliferation to BGP, Cyn d 1 and Cyn d 1 peptides was observed with a marked decrease in the IL-5:IFN-γ ratio. <i>Conclusions:</i> Cyn d 1 is a major T cell allergen of BGP. Decreased Cyn d 1-specific IL-5 dominant T cell responses were observed in association with clinically effective treatment with the 50% BGP and 50% 7-grass mix. Identified dominant T cell regions of Cyn d 1 should facilitate safer vaccine development for BGP-induced asthma in addition to rhinitis.
Quantifying Hardware Security Using Joint Information Flow Analysis (2016)

Existing hardware design methodologies provide limited methods to detect security flaws or derive a measure on how well a mitigation technique protects the system. Information flow analysis provides a powerful method to test and verify a design against security properties that are typically expressed using the notion of noninterference. While this is useful in many scenarios, it does have drawbacks primarily related to its strict enforcement of limiting all information flows - even those that could only occur in rare circumstances. Quantitative metrics based upon information theoretic measures provide an approach to loosen such restrictions. Furthermore, they are useful in understanding the effectiveness of security mitigations techniques. In this work, we discuss information flow analysis using noninterference and qualitative metrics. We describe how to use them in a synergistic manner to perform joint information flow analysis. And we use this novel technique to analyze security properties across several different hardware cryptographic cores.
Persistence of Long-lived Memory B Cells specific to Duffy Binding Protein in individuals exposed to Plasmodium vivax (2018)

The major challenge in designing a protective Duffy binding protein region II (DBPII)-based vaccine against blood-stage vivax malaria is the high number of polymorphisms in critical residues targeted by binding-inhibitory antibodies. Here, longevity of antibody and memory B cell response (MBCs) to DBL-TH variants, DBL-TH2, -TH4, -TH5, -TH6 and -TH9 were analyzed in P. vivax-exposed individuals living in a low malaria transmission area of southern Thailand. Antibody to DBL-TH variants were significantly detected during P. vivax infection and it was persisted for up to 9 months post-infection. However, DBL-TH-specific MBC responses were stably maintained longer than antibody response, at least 3 years post-infection in the absence of re-infection. Phenotyping of B cell subsets showed the expansion of activated and atypical MBCs during acute and recovery phase of infection. While the persistence of DBL-TH-specific MBCs was found in individuals who had activated and atypical MBC expansion, anti-DBL-TH antibody responses was rapidly declined in plasma. The data suggested that these two MBCs were triggered by P. vivax infection, its expansion and stability may have impact on antibody responses. Our results provided evidence for ability of DBPII variant antigens in induction of long-lasting MBCs among individuals who were living in low malaria endemicity.
Molecular cloning and characterization of the human p27<sup>Kip1</sup> gene promoter<sup>1</sup> (1997)

p27Kip1 is an inhibitor of multiple cyclin-dependent kinases (cdk), and can arrest the cell-cycle progression by inhibiting the phosphorylation of the retinoblastoma gene family products. Tumor formation in p27Kip1 knockout mice clearly shows that p27Kip1 plays an important role in inhibiting tumor formation and progression. To investigate the mechanism of transcriptional p27Kip1 gene expression, we isolated the genomic DNA fragment of the 5' flanking region of the human p27Kip1 gene and characterized its promoter region. The human p27Kip1 promoter is TATA-less, and the sequence is highly homologous to the murine p27Kip1 promoter sequence. In the promoter assay, deletion from -774 to -435 relative to the initiating codon resulted in a 15-20-fold reduction of the p27Kip1 promoter activity, suggesting that the elements for basal promoter activity exist in this highly conserved 340 bp region, where putative CTF and ATF sites are conserved.
Spatially resolved microrheology using localized coherence volumes (2002)

We propose an optical technique, based on dynamic light scattering, for investigating the local rheological response of a complex fluid over a frequency range larger than that provided by standard mechanical instrumentation. The low-coherence radiation used in a fiber optics configuration allows the measurements to be confined to a small volume around a tenth of a picoliter. The ability of the method to accurately measure both loss and storage moduli has been tested using both simple Newtonian liquids and viscoelastic, complex fluids. The possibility to monitor liquid-gel transitions in polymer solutions has also been demonstrated. The unique capability of the technique to localize the measurement volume suggests that this novel approach can be used for three-dimensional mapping of rheological properties in heterogeneous systems.
Advanced Signal Analysis of an Electrical Submersible Pump Failure Due to Scaling (2013)

Abstract The present paper is concerned with a study of electrical submersible pump failure due to scale build-up. From motor current signals recorded several weeks before the failure, weak fluctuations were recorded, indicating a change in the motor load. The advanced signal analysis of the motor current data revealed the presence of a dynamical character of the electrical submersible pump signal when scale started rapidly building up in the pump stages. Based on the raw data from the motor current draw a dynamical cascade was identified from the current marked with the superimposition of several characteristic frequencies added in time and developing a chaotic trend. The analysis is conducted with different signal analysis recognition tools such as Fourier transform, wavelet transform and chaotic attractors, which describe the nature of the scale signature in the current logs clearly. This analysis can be the first step towards developing real time diagnostic tools to predict ESP failures and acting accordingly.
Identification and molecular cloning of a gene encoding a fibronectin‐binding protein (CadF) from <i>Campylobacter jejuni</i> (1997)

Campylobacter jejuni, a Gram-negative bacterium, is a common cause of gastrointestinal disease. By analogy with other enteric pathogens such as Salmonella and Shigella, the ability of C. jejuni to bind to host cells is thought to be essential in the pathogenesis of enteritis. Scanning electron microscopy of infected INT407 cells suggested that C. jejuni bound to a component of the extracellular matrix. Binding assays using immobilized extracellular matrix proteins and soluble fibronectin showed specific and saturable binding of fibronectin to C. jejuni. Ligand immunoblot assays using 125I-labelled fibronectin revealed specific binding to an outer membrane protein with an apparent molecular mass of 37 kDa. A rabbit antiserum, raised against the gel-purified protein, reacted with a 37 kDa protein in all C. jejuni isolates (n = 15) as tested by immunoblot analysis. Antibodies present in convalescent serum from C. jejuni-infected individuals also recognized a 37 kDa protein. The gene encoding the immunoreactive 37kDa protein was cloned and sequenced. Sequencing of overlapping DNA fragments revealed an open reading frame (ORF) that encodes a protein of 326 amino acids with a calculated molecular mass of 36872Da. The deduced amino acid sequence of the ORF exhibited 52% similarity and 28% identity to the root adhesin protein from Pseudomonas fluorescens. Isogenic C. jejuni mutants which lack the 37 kDa outer membrane protein, which we have termed CadF, displayed significantly reduced binding to fibronectin. Biotinylated fibronectin bound to a protein with an apparent molecular mass of 37 kDa in the outer membrane protein extracts from wild-type C. jejuni as judged by ligand-binding blots. These results indicate that the binding of C. jejuni to fibronectin is mediated by the 37 kDa outer membrane protein which is conserved among C. jejuni isolates.
The Transcriptional Program following p53 Activation (2000)

Slightly more than half of all human cancers sustainmutations in the p53 gene (Hollstein et al. 1991; Bennettet al. 1992), and germ-line mutations in this gene lead tovarious types of cancers (Malkin et al. 1990). The wildtype p53 gene can block cellular transformation by activated oncogenes in vitro (Finlay et al. 1989) and tumorcell growth in vivo (Shaw et al. 1992; Xu et al. 1997). Anormal cell maintains low levels of the p53 protein. Thelevels and the transcriptional activity of the p53 proteinincrease in response to cellular stress, such as DNA damage, activation of oncogenes, viral infection, hypoxia, orlow levels of ribonucleoside triphosphate pools (Levine1997). In response to increased levels of the p53 protein,cells undergo either cell cycle arrest or apoptosis depending on the level of p53, the cell type, or the presence orabsence of activated oncogenes. This eliminates affectedcells and prevents a high mutation rate by blocking theduplication of damaged DNA (Levine 1997; Prives andHall 1999)...
Microbial transformation of 8-chloro-10,11-dihydrodibenz(b,f)(1,4)oxazepine by fungi (1977)

The microbial transformation of 8-chloro-10,11-dihydrodibenz(b,f)(1,4)oxazepine (compound I) was undertaken to obtain new derivatives. Compound I was transformed by Hormodendrum sp. (NRRL 8133) to 8-chloro-10,11-dihydrodibenz(b,f)(1,4)oxazepine-11-one (compound II) and 2-(2-amino-4-chlorophenoxy)benzyl alcohol (compound IV). Microbial cleavage of the nonaromatic ring to form compound IV was accomplished by several other fungi. Compound I was transformed to 8-chlorodibenz(b,f)(1,4)oxazepine (compound III) by Hormodendrum cladosporioides (NRRL 8132).
Gait analysis using shoe-worn inertial sensors (2014)

Spatiotemporal gait analysis with body worn inertial sensors improves diagnosis in clinical practice. Most of the gait performance measures are affected by walking speed. However, it has not been investigated that how much information foot clearance parameters share with the key parameters of gait performance domains. Using shoe-worn inertial sensors and previously validated algorithm we measured spatiotemporal as well as clearance gait parameters in a cohort of able-bodied adults over the age of 65 (N=879). Principal components analysis showed that variability of foot clearance parameters contribute to the main variability in gait data. Moreover, only weak to moderate correlation of gait speed and stride length with some clearance parameters has been observed. We recommend the assessment of clearance parameters during gait analysis in addition to parameters such as gait speed, bearing in mind the importance of foot clearance measures in obstacle negotiation, slipping and tripping related falls.
SAPO‐34 Seeds and Membranes Prepared Using Multiple Structure Directing Agents (2008)

SAPO-34 membranes were synthesized by seeding SAPO-34 crystals on porous stainless steel supports. By using combinations of structure directing agents (SDAs) for both seed and membrane preparation, membranes with high fluxes and high selectivities for CO2/CH4 and CO2/H2 separations were prepared. Membranes prepared with smaller, homogeneous cubic and rectangular crystals (< 1 μm) displayed superior separation performance.

<title>Target-type probability combining algorithms for multisensor tracking</title> (2001)

Algorithms for the handing of target type information in an operational multi-sensor tracking system are presented. The paper discusses recursive target type estimation, computation of crosses from passive data (strobe track triangulation), as well as the computation of the quality of the crosses for deghosting purposes. The focus is on Bayesian algorithms that operate in the discrete target type probability space, and on the approximations introduced for computational complexity reduction. The centralized algorithms are able to fuse discrete data from a variety of sensors and information sources, including IFF equipment, ESM's, IRST's as well as flight envelopes estimated from track data. All algorithms are asynchronous and can be tuned to handle clutter, erroneous associations as well as missed and erroneous detections. A key to obtain this ability is the inclusion of data forgetting by a procedure for propagation of target type probability states between measurement time instances. Other important properties of the algorithms are their abilities to handle ambiguous data and scenarios. The above aspects are illustrated in a simulations study. The simulation setup includes 46 air targets of 6 different types that are tracked by 5 airborne sensor platforms using ESM's and IRST's as data sources.
Temperature characteristics of the substrate for Lamb wave type elastic wave devices (2006)

Abstract Plate wave (Lamb wave) propagation in an extremely thin quartz substrate is analyzed. A cut angle is sought that exhibits an ultrastable temperature dependence of the frequency characteristics so that the frequency changes little with temperature. Highly stable temperature characteristics of the frequency indicating second‐ and third‐order curves are obtained. Theoretical and experimental investigations of the temperature characteristics of the frequency of Lamb waves propagating in an AT‐cut quartz substrate indicate excellent agreement between the two, confirming that the reliability of the results of the present analysis is high. © 2006 Wiley Periodicals, Inc.

A Novel No-Reference Stereoscopic Image Quality Assessment Method (2012)

No-reference stereoscopic image quality assessment (NR-SIQA) is an important research issue in three- dimensional researches. In this paper, a novel NR- SIQA method is proposed by analyzing the detail characteristic of the specific distortion type, and distortion-specific features are extracted to describe the distorted stereoscopic image. The relationship between stereoscopic features and subjective score is established by using support vector regression (SVR). Experimental results show that compared with the full-reference structural similarity image quality (SSIM) assessment method, the proposed method is more effective in quantifying image quality.
Optimal operation of power systems constrained by transient stability (2001)

Abstract Optimal power flow (OPF) with transient stability constraints is a nonlinear optimization problem in functional space that is not easy to deal with precisely even for small‐scale power systems. Instead of directly tackling this tricky problem, in this paper, OPF with transient stability constraints (OTS) is equivalently converted into an optimization problem in Euclidean space via a constraint transcription, which can be solved by any standard nonlinear programming techniques adopted by OPF. The transformed OTS problem has the same variables as those of OPF in form, and is tractable even for large‐scale power systems with a large number of transient stability constraints. © 2001 Scripta Technica, Electr Eng Jpn, 137(1): 17–27, 2001
Development of computer tablet software for clinical quantification of lateral knee compartment translation during the pivot shift test (2015)

The pivot shift test is a commonly used clinical examination by orthopedic surgeons to evaluate knee function following injury. However, the test can only be graded subjectively by the examiner. Therefore, the purpose of this study is to develop software for a computer tablet to quantify anterior translation of the lateral knee compartment during the pivot shift test. Based on the simple image analysis method, software for a computer tablet was developed with the following primary design constraint - the software should be easy to use in a clinical setting and it should not slow down an outpatient visit. Translation of the lateral compartment of the intact knee was 2.0 ± 0.2 mm and for the anterior cruciate ligament-deficient knee was 8.9 ± 0.9 mm (p < 0.001). Intra-tester (ICC range = 0.913 to 0.999) and inter-tester (ICC = 0.949) reliability were excellent for the repeatability assessments. Overall, the average percent error of measuring simulated translation of the lateral knee compartment with the tablet parallel to the monitor increased from 2.8% at 50 cm distance to 7.7% at 200 cm. Deviation from the parallel position of the tablet did not have a significant effect until a tablet angle of 45°. Average percent error during anterior translation of the lateral knee compartment of 6mm was 2.2% compared to 6.2% for 2 mm of translation. The software provides reliable, objective, and quantitative data on translation of the lateral knee compartment during the pivot shift test and meets the design constraints posed by the clinical setting.

Time-constrained dynamic semantic compression for video indexing and interactive searching (2005)

We define and present a new model for semantic video compression and searching, and apply this model to several video genres, with special emphasis on instructional videos. In this model, a semantic distance based on the video genre is computed between adjacent frames in a dynamic video buffer of predetermined size, and redundant "unkey" frames leak from the buffer interior into a data structure "leakage history directed acyclic graph" (LHDAG) which records the relative importance of these frames. What exits the buffer forms a highly compressed video stream consisting of only the most semantically significant video frames, whereas the LHDAG permits efficient semantic exploration of the video interior. This novel hierarchical but context-sensitive data structure LHDAG permits the searching of the video at display rates that are proportional to visual significance, at levels of semantic density selectable by the user. The data structure is simple to create and query, and appears to be more psychologically plausible than more straightforward fixed sampling indexing schemes. We empirically display and mathematically analyze the relationships of the video buffer's leaking rate, buffer size, and exit delay, and demonstrate its performance on several extended videos. The flexibility of the method is indicated by its demonstration on two very different definitions of semantic significance: color similarity, and content ("ink pixel") similarity.
Development and Validation of a Competitive ELISA Based on Bovine Monoclonal Antibodies for the Detection of Neutralizing Antibodies against Foot-and-Mouth Disease Virus Serotype A (2022)

The level of neutralizing antibodies in vaccinated animals is directly related to their level of protection against a virus challenge. The virus neutralization test (VNT) is a "gold standard" method for detecting neutralizing antibodies against foot-and-mouth disease virus (FMDV). However, VNT requires high-containment facilities that can handle live viruses and is not suitable for large-scale serological surveillance. In this study, a bovine broadly neutralizing monoclonal antibody (W145) against FMDV serotype A was successfully produced using fluorescence-based single-B-cell antibody technology. Using biotinylated W145 as a detector antibody and another bovine cross-reactive monoclonal antibody, E32, which was produced previously as a capture antibody, a competitive enzyme-linked immunosorbent assay for the detection of neutralizing antibodies (NAC-ELISA) against FMDV serotype A was developed. The specificity and sensitivity of the assay were evaluated to be 99.04% and 100%, respectively. A statistically significant correlation (<i>r</i> = 0.9334, <i>P</i> < 0.0001) was observed between the NAC-ELISA titers and the VNT titers, suggesting that the NAC-ELISA could detect neutralizing antibodies against FMDV serotype A and could be used to evaluate protective immunity.
