User Identification and Tracking with online device fingerprints fusion (2012)

Identification and Tracking of online digital identity has been significant issue around efforts on cyber security. The purpose of this research is to demonstrate how to utilized information being emitted from digital devices carried by suspicious user. In this paper, techniques to identify owner of digital devices connected to the Internet or local network are proposed. Techniques include tracing physical id of network interface, profiling of network traffic pattern of devices, Bluetooth device signals, web browser finger printings, and header information of e-mail messages. Each devices connected to computer network has its own finger print such as physical MAC address, network traffic generated by operating systems and its installed applications thus such information can be applied to identify and track unique digital device. If the device is personal item such as smartphone or personal computer owned by a specific person this information is being able to use to detect and trace location of the person. Each web browser installed on such devices also has its unique characteristics such as version, installed fonts, and difference in its settings, such information can be used to identify a person. E-mail message has significant information in its header, by analyzing messages headers certain amount of information of its sender are extracted. This is also used to detect impersonation of a message sender. By integrating these information obtained through such monitoring activity and related network sensors we are able to identify existence and physical location of a targeted personnel, to monitor their behavior and also we are able to use such data as evidence for law suites. Preservation of privacy is the issued to be considered for such application and this would discuss how to balance between user privacy and traceability of users in certain types of network.
Indonesian License Plate Recognition Using Convolutional Neural Network (2018)

License plate is a part of vehicle's identity. In modern countries, license plate recognition has been developed to collect traffic activity information. The performance of license plate recognition system tend to drop when the input picture contains noises like illumination, dirt, and scratches which cover one or more characters in the license plate. This research was focused on Indonesian license plate as many license plates in Indonesia had various noises like plastic cover and scratches which complicate the recognition. In this study, Indonesian license plate recognition is formed using a Convolutional Neural Network (CNN) which is known to have good performance in recognizing objects, even though the objects are obscured to some degree. Sliding window is used in this study for replace character segmentation. CNN will predict images in every area of window. The highest performance for the whole system to the normal data test is 87.36% and noised data test is 44.93%.
Frame relay: protocols and private network applications (1989)

The authors discuss possible protocols for both data transfer and connection control in frame relay and describe the application of frame relay in private ISDN-based networks. First, the functions and frame structure associated with the frame sublayer and the operation of the frame-relaying process are reviewed. Then, the Q.931 procedures are examined for control of frame-relay connections at user-network interfaces, as well as the transport of the associated Q.931 messages across these interfaces, for several scenarios. Finally, the use of frame relay as a transport mechanism is described for all forms of packet-oriented traffic in private networks, focusing in particular on the synergy between the use of Q.931 procedures with appropriate extensions for inner-node signaling and the use of frame-relay to transport Q.931 messages within the network. Possibilities are briefly suggested for the evolution of private networks with frame relay into integrated packet networks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Air-Liquid Interface Culture of Serially Passaged Human Nasal Epithelial Cell Monolayer for<i>In Vitro</i>Drug Transport Studies (2005)

The objective of this study was to establish a drug transport study using human nasal epithelial (HNE) cell monolayers cultured by the air-liquid interface (ALI) method using serum-free medium (BEGM:DME/F12, 50:50). The cells were developed and characterized in comparison to those that have been previously cultured by the liquid-covered culture (LCC) method. The epithelial cell monolayer cultured by the ALI method resulted in a significantly higher transepithelial electrical resistance value (3,453 +/- 302 ohm x cm(2)) that was maintained (>1,000 ohm x cm(2)) for up to 20 days compared with that cultured by the LCC method. Observation by scanning electron microscopy revealed mature cilia after 2 weeks in the ALI culture, while flatten unhealthy ciliated cells were observed in the LCC method. After 21 days, higher level of MUC5AC and 8 mRNA were expressed in ALI culture which confirmed the secretory differentiation of HNE monolayers in vitro. No significant difference in the permeability coefficients of a model hydrophilic marker ((14)C-mannitol) and a lipophilic drug (budesonide) was observed between the two conditions on day 7. The passage 2-3 of the HNE monolayer using ALI condition retained the morphology and differentiated features of normal epithelium. Thus it would be a suitable model for in vitro nasal drug delivery studies.
Targeting the Treponemal Microbiome of Digital Dermatitis Infections by High-Resolution Phylogenetic Analyses and Comparison with Fluorescent <i>In Situ</i> Hybridization (2013)

Modern pyrosequencing technology allows for a more comprehensive approach than traditional Sanger sequencing for elucidating the etiology of bovine digital dermatitis. We sought to describe the composition and diversity of treponemes in digital dermatitis lesions by using deep sequencing of the V3 and V4 hypervariable regions of the 16S rRNA gene coupled with species-level taxonomic identification. Treponema-specific 16S rRNA gene PCRs and pyrosequencing were performed on biopsy specimens originating from 10 different Catalan dairy herds (n = 36) with digital dermatitis, and this analysis yielded 75,297 sequences. We identified 20 different taxa, including a potentially novel phylotype that displayed 95% sequence identity to members of the Treponema denticola/Treponema pedis-like cluster. Species frequencies and abundances that were determined by pyrosequencing analysis were highly correlated with the results of fluorescent in situ hybridization using phylotype-specific oligonucleotide probes. In a limited number of animals from a single geographic region, we detected most of the Treponema phylotypes that were described in previous investigations of digital dermatitis. Additionally, we identified a number of phylotypes that mapped to oral treponemes of humans and dogs that had not been reported for digital dermatitis lesions. The results presented here support previous observations of a polytreponemal etiology of infections, with Treponema phagedenis-like, Treponema medium/Treponema vincentii-like, and T. denticola/T. pedis-like phylotypes being highly associated with disease. Using this new approach, it has become feasible to study large herds and their surrounding environments, which might provide a basis for a better understanding of the pathogenesis of this disease.
Computers: the best friends a human genome ever had (1989)

Mapping and sequencing the human genome will generate large amounts of data, which must be sorted, analyzed, and stored for rapid retrieval to complete this enormous task. Computers and their software programs provide the most important tool to the molecular biologist today. A discussion of current capabilities and future needs in computer hardware and software for the human genome project is the topic of this paper. The use of computer programs to generate restriction maps, manage clone libraries, manage sequence projects, and generate consensus sequences is presented. The use of computers to communicate useful information rapidly to scientific colleagues is also mentioned. The role of both GenBank and BIONET is central to the dissemination and analysis of sequence information. The capabilities of electronic communication worldwide for assisting this project is available on the BIONET National Computer Resource, using existing networks.
Discrimination of the toxigenic dinoflagellates <i>Alexandrium tamarense</i> and <i>A. ostenfeldii</i> in co-occurring natural populations from Scottish coastal waters (2003)

Blooms of the toxic dinoflagellate Alexandrium tamarense (Lebour) Balech, a known producer of potent neurotoxins associated with paralytic shellfish poisoning (PSP), are common annual events along the Scottish east coast. The cooccurrence of a second Alexandrium species, A. ostenfeldii (Paulsen) Balech & Tangen is reported in this study from waters of the Scottish east coast. The latter species has been suspected to be an alternative source of PSP toxins in northern Europe. Recent identification of toxic macrocyclic imines known as spirolides in A. ostenfeldii indicates a potential new challenge for monitoring toxic Alexandrium species and their respective toxins in natural populations. In mixed Phytoplankton assemblages, Alexandrium species are difficult to discriminate accurately by conventional light microscopy. Species-specific rRNA probes based upon 18S and 28S ribosomal DNA sequences were developed for A. ostenfeldii and tested by dot-blot and fluorescence in situ hybridization (FISH) techniques. Hybridization patterns of A. ostenfeldii probes for cultured Alexandrium isolates, and cells from field populations from the Scottish east coast, were compared with those of rDNA probes for A. tamarense and a universal dinoflagellate probe. Alexandrium cell numbers in field samples determined by whole-cell in situ hybridization were much lower than those determined by optical microscopy with the Utermöhi method involving sedimentation chambers, but the results were highly correlated (e.g. r 2 = 0.94; n = 6 for A. tamarense). Determination of spirolides and PSP toxins by instrumental analysis on board ship demonstrated the presence of both toxin groups in plankton assemblages collected from surface waters near the Orkney Islands, and confirmed the association of A. ostenfeldii with spirolides in northern Europe. These results show that rRNA probes for A. tamarense and A. ostenfeldii are useful, albeit only semi-quantitative, tools to detect and discriminate these species in field studies.
An herbivore elicitor activates the gene for indole emission in maize (2000)

Maize and a variety of other plant species release volatile compounds in response to herbivore attack that serve as chemical cues to signal natural enemies of the feeding herbivore. N-(17-hydroxylinolenoyl)-l-glutamine is an elicitor component that has been isolated and chemically characterized from the regurgitant of the herbivore-pest beet armyworm. This fatty acid derivative, referred to as volicitin, triggers the synthesis and release of volatile components, including terpenoids and indole in maize. Here we report on a previously unidentified enzyme, indole-3-glycerol phosphate lyase (IGL), that catalyzes the formation of free indole and is selectively activated by volicitin. IGL's enzymatic properties are similar to BX1, a maize enzyme that serves as the entry point to the secondary defense metabolites DIBOA and DIMBOA. Gene-sequence analysis indicates that Igl and Bx1 are evolutionarily related to the tryptophan synthase alpha subunit.
Cryopreservation and Hypothermal Storage of Hematopoietic Stem Cells (2015)

The recent availability of commercially available
storage media (CryoStor™ and HypoThermosol™) designed for optimal
long-term and short-term hematopoietic stem cell (HSC) storage
prompted an evaluation of hematopoietic stem cell and hematopoietic
progenitor cell (HSC/P) viability and functionality after storage
in these media formulations, compared with the conventional media
used at Hoxworth Blood Center. Three human umbilical cord blood
units (CBUs) were cryopreserved in CryoStor5 (CS5), CryoStor10
(CS10), and a conventional internally prepared cryopreservation
medium, then analyzed post-thaw for viability and recovery of
several mature and immature hematopoietic cell types, as well as
for clonogenic capacity, and proliferation potential. Flow
cytometric analysis indicated similar post-thaw viability of most
cell subsets cryopreserved in CS5, and CS10 compared to the
conventional cryopreservation medium (containing 5 %
Dimethylsulfoxide (DMSO) and 2.5 % hydroxyethyl starch). This
variation in viability was not statistically significant (p-value
0.2-1). Bromodeoxyuridine (BrdU) uptake was used to measure the
ability of the frozen/thawed cells to proliferate in culture for 48
h in response to stem cell factor (SCF), FLt-3 ligand (FLt-3) and
thrombopoietin (TPO). Proliferation potential and clonogenic
capacity were both slightly better with after freezing in CS10;
however, the differences were not statistically significant. This
study shows that the conventional medium for cryopreservation used
in our laboratory is similarly effective, compared with CS5 or CS10
media, in protecting the cryopreserved CBU derived HSC/P
products.The same analytical methods were used to compare
HypoThermosol® (HTR-FRS®), which is designed for short-term
refrigerated storage of hematopoietic cells, to a locally prepared
medium containing Plasma-Lyte A and 0.5 % human serum albumin
(HSA). Measurements were performed after 24, 48 and 72 h of cold
storage (4°C). Results showed similar viability and recovery after
24 h of storage, but after 48 and 72 h, a significant decline in
viability occurred in a few of the subsets when stored in
Plasma-Lyte A/HSA medium, compared to when stored in HTS-FRS®.
Differences in clonogenic capacity and proliferation potential were
not significant, however the cells’ proliferation potential was
slightly better after storage in HTS-FSR®. Taken together, these
results indicate that the HTS-FRS® storage media preserves
hematopoietic cell function better than Plasma-Lyte A/ 0.5 % HSA,
especially if the cells are to be stored for more than 24 hours.It
is possible that these in-vitro results could translate to improved
engraftment after storing umbilical cord blood, bone marrow or
mobilized peripheral blood in these new media.
University of California, Davis Long-Range Development Plan: A Davis Smart Mobility Model (2003)

The goal of the Smart Mobility Model project was to optimize individual mobility options through improved connectivity among modes, enhanced techniques to link landuse planning and transportation system design, advanced information technologies, and clean-fuel vehicles. The California PATH/Caltrans partnership with the University of California, Davis (UC Davis) was initiated after campus planners expressed interest in learning how innovative mobility services and technologies (such as carsharing and smart parking management) might help to alleviate the transportation impacts of a campus expansion, expected to result in the arrival of more than 9,000 additional students, staff, and faculty in the coming decade. The campus is in the midst of a multi-year process to approve a Long Range Development Plan (LRDP) that will guide all aspects of this expansion. The study also focused on residents and impacts on Davis and the surrounding region. Additional project supporters included: UC Davis Office of Resource Management and Planning, UC Davis Student Housing, and UC Davis Transportation and Parking Services. The UC Davis Institute for Transportation Studies was also a project partner.
Interactive Voice Response with Pattern Recognition Based on Artificial Neural Network Approach (2007)

In the present era of information technology, information nowadays is just a telephone call away. However, applications such as telephone banking etc. need extra security for making it a reliable service for the people. Application of PIN code/password via telephone is not enough and additional user specific information is required that can protect the user identity in a more effective way. In this paper, we propose an approach that uses interactive voice response (IVR) with pattern recognition based on neural networks. In this case, after entering the correct password the user is asked to input his voice sample which is used to verify his identity. The addition of voice pattern recognition in the authentication process can potentially further enhance the security level. As both are simultaneously applied so there is lesser probability of misuse. The developed system is fully compliant with hind line phone system.
Hypoxia-inducible Transcription Factor-2α in Endothelial Cells Regulates Tumor Neovascularization through Activation of Ephrin A1 (2008)

The hypoxia-inducible transcription factors (HIF)-1alpha and -2alpha mediate responses to hypoxia, such as tumor neovascularization. To determine the function of HIF-2alpha in vascular endothelial cells (ECs), we examined vascular formation in HIF-2alpha knockdown (kd/kd) mice transplanted with tumors. We observed that both the tumor size and the number of large vessels growing within transplanted melanomas were significantly reduced in kd/kd recipients compared with wild-type (WT) mice. In contrast, we observed a similar extent of vascular formation within fibrosarcomas transplanted from either kd/kd or WT mice into WT recipients. Thus, HIF-2alpha expression in host animal ECs, but not in the tumor cells, is crucial for tumor neovascularization. HIF-2alpha may function through ephrin A1 as the expression of ephrin A1 and related genes was markedly reduced in kd/kd ECs, and HIF-2alpha specifically bound a hypoxia-response element sequence in the ephrin A1 promoter. Treatment of WT ECs with an ephrin A1 inhibitor (ephrin A1-Fc) also impaired neovascularization. We conclude that in ECs, HIF-2alpha plays an essential role in vascular remodeling during tumor vascularization through activation of at least ephrin A1.
Real-Time Magnetic Resonance Imaging of Temporomandibular Joint Dynamics (2011)

This study evaluated the use of a novel real-time MRI technique based on fast low angle shot (FLASH) MRI with radial encoding, gridding reconstruction, and sliding window for the assessment of temporomandibular joint (TMJ) dynamics in a cohort of 30 young volunteers without prior diagnosis of TMJ pathology. High-resolution images (0.75 0.75 mm 2 , 5 mm section thickness) were obtained at 3 frames per second for active jaw movements without adjunctive devices. Real-time movies were evaluated with respect to image artefacts, anatomical visibility, diagnostic confidence, and TMJ function. During the entire opening and closing of the mouth, the relative positions of the mandibular condyle and articular disc were well depicted. Mean scores were 1.01 0.65 for motion artefacts (scale: 0 = no to 3 = severe artefacts) and 2.03 0.71 for anatomical detectability (scale: 1 = excellent to 5 = not visible). High inter-observer agreements were found for assessments of mandibular condyle movements ( = 0.83) and articular disc displacements ( = 0.91). In latter cases, the point of disc reduction could precisely be identified. In conclusion, the proposed real-time MRI method offers robust access to TMJ dynamics with good image quality.
A Novel Visual-Vocabulary-Translator-Based Cross-Domain Image Matching (2017)

Cross-domain image matching, which investigates the problem of searching images across different visual domains such as photo, sketch, or painting, has attracted intensive attention in computer vision due to its widespread application. Unlike intra-domain matching, cross-domain images appear quite different in various characteristics. This leads to the failure of most existing approaches. However, the great difference between cross-domain images is just like the huge gap between English and Chinese. The two languages are linked up by an English-Chinese translation dictionary. Inspired by this idea, in this paper, we purpose a novel visual vocabulary translator for cross-domain image matching. This translator consists of two main modules: one is a pair of vocabulary trees which can be regarded as the codebooks in their respective fields, whereas the other is the index file based on cross-domain image pair. Through such a translator, a feature from one visual domain can be translated into another. The proposed algorithm is extensively evaluated on two kinds of cross-domain matching tasks, i.e., photo-to-sketch matching and photo-to-painting matching. Experimental results demonstrate that the effectiveness and efficiency of the visual vocabulary translator. And by employing this translator, the proposed algorithm achieves satisfactory performance in different matching systems. Furthermore, our work shows great potential in multiple visual domains.
XML data management and XPath evaluation in wireless sensor networks (2009)

XML is the defacto standard for data exchange applications like those in the WWW. However, due to the limited hardware resources, wireless sensor networks abstain from using verbose data formats like XML. Nevertheless, XML as a standardized data exchange format in wireless sensor networks is a means to support more complex data management and heterogeneous networks. Moreover, XML is a key feature towards service-oriented sensor networks that exchange structured information by using SOAP. Recent work has shown that XML can be compressed to meet the general hardware restrictions of sensor nodes while still supporting updates. In this work we outline the vision and benefits of XML usage in wireless sensor networks, show how to evaluate XML queries in wireless sensor networks and how query results can be compressed to lower the comunication overhead. We therefore present an XPath engine on updateable compressed XML data for sensor nodes and an experimental evaluation showing that the performance of our XPath engine fulfills the requirements of today's applications even on sensor nodes.
A Position Sensorless Method for Direct Torque Control With Space Vector Modulation of Hybrid Excitation Flux-Switching Generator (2012)

A position sensorless method for direct torque control with space vector modulation (DTC-SVM) of hybrid excitation flux-switching generator (HEFS) is presented. Based on the synchronous angular frequency acquired by a m-order low-pass filter, a programmable first-order low-pass filter together with a band pass filter and a coordinate transformation is used to estimate the stator flux-linkages without magnitude and phase angle errors. Thus, the instantaneous torque and the rotor position can be accurately estimated based on the precise stator flux-linkages. The DTC-SVM scheme of the HEFS using the proposed position sensorless method exhibits good steady-state and dynamic performance, which is verified by experimental results.
Effects of surface metal layer on the thermal contact resistance of carbon nanotube arrays (2005)

We present a type of thermal interface material by incorporating carbon nanotube arrays into polydimethylsiloxane. Particularly, we evaporated a 1-μm-thick aluminum layer on the top of the raw carbon nanotube array, which served as a heat current collector to decrease the thermal contact resistance. The thermal conductivity and thermal contact resistance of the materials were measured by the steady-state method. Comparing to the material without the heat current collector, the thermal contact resistance was remarkably reduced by about 50%.
