A systematic approach towards user-centric privacy and security for smart camera networks (2010)

The majority of research in the field of camera networks is targeted at distributed and cooperative processing, advanced computer vision algorithms or the development of embedded, ubiquitous camera systems. Privacy and security are topics that are often overlooked or considered as an afterthought. With the digitalization of visual surveillance, data can easily be stored and accessed. This raises the question how confidential data can be protected, authenticity and integrity can be ensured and access can be restricted. This work discusses security and privacy issues relevant in the context of visual surveillance and camera networks. We try to capture the state of the art on these aspects in the available literature and highlight areas that require special consideration. We present a concept of a privacy-preserving camera system based on Trusted Computing. In our system-level approach, we consider privacy and security as primary goals without limiting the overall usefulness of a camera system.
Toxicity of 8-Hydroxyquinoline on Embryos and Larvae of Misgurnus anguillicaudatus (2010)

The research was to investigate 8-Hydroxyquinoline on fish embryo and larval toxicity in the water.Different embryo stages and larvae of Misgurnus anguillicaudatus,including blastoderm formed,mid-gastrulation,neurula stage,tail bud stage and larval fish hatched stage,was treated with different concentrations of 8-hydroxyquinoline to test the changes of embryo hatching rate and malformation rate,larval fish mortality and the changes in body length.Results showed that,with the increase in the concentration of 8-hydroxyquinoline,compared with the control group,the hatching rate of M.anguillicaudatus embryos declined to 83.5%,74%,61% and 79%,respectively,and the abnomal embryos rate increased to 63%,75%,72% and 64%,respectively.The mortality ratio of M.anguillicaudatus larvae increased from 3% to 100%,the treatment groups were shorter than the control group,with a certain degree of dosage-effect relationship.We concluded that 8-hydroxyquinoline had inhibited the development,teratogenic,lethal effect on the M.anguillicaudatus embryos and larvae,showing obvious toxicity.
Destruction of Cucumber Green Mottle Mosaic Virus by Heat Treatment and Rapid Detection of Virus Inactivation by RT-PCR (2003)

Heat treatment is commonly used to control viral contamination of seeds. To study virus inactivation, virus was purified from seeds contaminated with Cucumber green mottle mosaic virus (CGMMV) after various heat treatments. CGMMV particles were observed to be physically disrupted by high temperature. Analysis of viral RNA revealed that the 5' and 3' termini of the genome were protected whereas regions between 2-2.5, 3.2-3.7 and 4-4.8 kb from the 5' terminus were not. Heat inactivation of virus on seeds was confirmed by RT-PCR using primers for a heat-sensitive region. The RT-PCR approach developed here may prove preferable to time- and labor-intensive bioassays for assessing virus heat inactivation.
A Psychophysical Study of Sensory Saltation With an Open Response Paradigm (2000)

Abstract As we develop new haptic interfaces, it is desirable to present haptic information in an intuitive and effective manner. The sensory saltation phenomenon is a haptic spatiotemporal illusion that, with the appropriate spatial and timing parameters, evoke a powerful perception of directional lines. Efforts are underway to develop a general-purpose haptic display based on sensory saltation that can find application in many areas including a haptic driving navigation guidance system. The current study is designed to test the hypothesis that saltatory signals can be readily perceived by human observers without training. Using a 3-by-3 tactor array, horizontal, vertical and diagonal saltatory lines are generated. An open response paradigm is used to permit subjects to describe saltatory signals with their own imagination. Results show that the saltatory signals used in this study share unique and consistent interpretations among the group of observers tested. Future work include a follow up study of the same saltatory signals using a standard absolute identification paradigm.
<i>J</i>-Coupling Nuclear Magnetic Resonance Spectroscopy of Liquids in nT Fields (2005)

In ultralow magnetic fields, liquid state nuclear magnetic resonance (NMR) spectra of homonuclear spin systems exhibit line widths dominated by their natural lifetime. Chemical shifts become negligible, and heteronuclear NMR spectra show predominantly the electron-mediated field-independent J-coupling. However, weak polarization and Larmor frequencies down to a few hertz require special detectors, such as Superconducting Quantum Interference Devices (SQUID), that also enable the simultaneous detection of broad band spectra of heteronuclear spin systems. We acquired spectra of 2,2,2-trifluoroethanol and trimethyl phosphate at detection fields varying from 444 nT to 3.34 muT after prepolarizing the sample in a field of 250 muT. Down to a 1H Larmor frequency of 40 Hz, the spectra of trifluoroethanol exhibited four clearly resolvable peaks. The numerical simulation agreed well with the measured spectra. Trimethyl phosphate exhibited two major groups of nonresolved proton lines. At 1H Larmor frequencies below 150 Hz, the separation of the two groups decreased, reflecting the transition from weakly to strongly coupled spin systems. Direct determination of 3J(H,P) from the peak separation is possible only at Larmor frequencies above 150 Hz. The experimental setup allowed an easy adjustment of the detection field over several octaves. This enabled us to adapt the detection field to the best-suited measurement window providing the maximum spectral information. Low-field NMR may open new applications, such as monitoring heteronuclear reactions, low-field imaging, simultaneous NMR/magnetoencephalography measurements, or quantum computing.
Optimization design of the decoder of streaming media player based on ARM (2017)

Streaming media technology is that continuous media transmits in the network using stream technology. It supports playing of audio and video files while they are being downloaded. So that users feel as smooth as playing local files when they broadcast network file. Due to that the amount of data of the audio and video files is very large, real-time broadcast is not an easy thing. It needs for data acquisition, compression, network transmission, decoding and playing for the client, as well as many other aspects. However, due to real-time broadcast brings unprecedented convenience, there is huge demand for embedded devices of supporting streaming media technology in market. Based on the ARM S3C2410 development board as the hardware platform, the Linux kernel 2.4.18 version as an embedded operating system, an embedded platform for streaming media player is built. On the platform, in order to implement the audio and video streaming transmission and smooth playback, the transplantation of streaming media player MPlayer and decoder of optimization are discussed.
Raspberry-like Silica Hollow Spheres:  Hierarchical Structures by Dual Latex−Surfactant Templating Route (2007)

Raspberry-like hollow SiO2 spheres were synthesized successfully through a dual latex-surfactant templating route. In this approach, cationic cetyltrimethylammonium (CTA(+)) micelles and microscale polystyrene (PS) latex were employed as structure-directing templates for constructing the inorganic hollow SiO2 spheres with hierarchical structures. The final product has been analyzed scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), single-angle X-ray diffraction (SAXRD), Brunauer-Emmett-Teller (BET) measurements, and Hg porosimetry measurements. The as-obtained hollow SiO2 spheres present a novel raspberry-like protruding surface morphology and possess hierarchical porous shells. Moreover, the factors that could impact the surface morphology and hierarchical porous structure are discussed, and the corresponding mechanism was proposed accordingly. This dual templating route is expected to be an effective means to pattern multiscale structures in the shell of the SiO2 microspheres; hence their potential applications could be greatly broadened.
The paper clip nasal dilator (1998)

A narrow nasal valve causes severe obstruction and is very difficult to fix. Many people have tried surgical approaches, including spreader grafts, with mixed results. Recently there have been appliances used to spread and open up the nasal valve, including Breathe Right (CNS Inc., Bloomington, MN) and Breathe With Eez (Breathe With Eez Corp., Brooklyn, NY). However these devices are expensive if used on a long-term basis. For example, Breathe Right costs $10 to $15 per month and Breathe With Eez costs $15 to $20 and gets lost easily. We would like to introduce an inexpensive device devised by a patient of ours for dilating the narrow nasal valve. Bending the paper clip in four steps. Oblique view of the paper clip nasal dilator. As illustrated in Figure 1, in Step 1 a paper clip is bent to straighten it out. In Step 2 the ends are then bent up so that the clip resembles the letter U. In Step 3 the two arms of the U are bent down at a perpendicular plane to the U. The final result is illustrated in Step 4. The bent paper clip is slipped into the nostril with each rounded end going into each nostril and the ends of the paper clip sticking out of the nostrils as shown in Figures 2 and 3. The paper clip can be adjusted as needed to widen or narrow the angles so that the fit is more comfortable. If necessary, the ends of the paper clip can be trimmed with a wire cutter so that they don't protrude so far. Frontal view of the paper clip nasal dilator. This paper clip nasal dilator is inexpensive, easy to make, adjustable, and very comfortable. By opening up the nasal valve, this device relieves nasal obstruction caused by a narrow nasal valve. We recommend fashioning the paper clip nasal dilator from a plastic-coated paper clip, since stainless steel will rust. One paper clip lasts approximately 1 month, so the final costs would be less than a penny per month.
Murine immune response to the <i>Neisseria meningitidis</i> group C capsular polysaccharide. II. Specificity. (1988)

As a means of further understanding the regulation of diversity and the development of protective immunity to the Neisseria meningitidis group C capsular polysaccharide (MCPS), we have generated and characterized, in detail, a panel of mAb against MCPS, a homopolymer of alpha(2----9)-sialic acid. Whereas the serum response to MCPS is restricted to the IgM and IgG3 isotypes, the panel of mAb includes, in addition, both IgG1 and IgG2b. Among 15 mAb of four isotypes, seven different specificities were observed based on direct binding in a fluorescence ELISA and precipitation in gel. Although all the mAb were derived from mice immunized with bacteria encapsulated with the native MCPS (strain C11), only 7 of 15 reacted with MCPS alone. Seven of 15 reacted with a natural O-acetyl-negative variant (OAc-, strain MC19) polysaccharide as well as with MCPS. Five of these reacted as much as 3 logs better with OAc- than MCPS and the other two reacted better with MCPS than OAc-. One mAb appeared to be alpha(2----9)-linkage specific as it reacted not only with MCPS and OAc-, but also with the capsular polysaccharide of Escherichia coli K92, a polymer of sialic acid linked alternately alpha(2----8) and alpha(2----9). None of the mAb reacted with the capsular polysaccharide of E. coli K1, a homopolymer of alpha(2----8)-sialic acid. In general, there was a good correlation between the ability to precipitate Ag in gel and to agglutinate bacteria; however, 3 of 15 mAb, all IgG3, did not conform to this rule in that they precipitated Ag but did not agglutinate bacteria of the relevant capsular specificity. Antibodies of both IgM and IgG isotypes and of both major specificities, MCPS-specific and those binding MCPS and OAc-, were bactericidal for strain C11, whereas only those reactive with OAc- were able to kill strain MC19.
Mapping the fodrin binding domain in CD45, a leukocyte membrane-associated tyrosine phosphatase. (1994)

CD45 belongs to a family of high molecular mass leukocyte glycoproteins. It contains both an intrinsic protein tyrosine phosphatase (PTPase) activity and a cytoskeleton binding site in its cytoplasmic domain. Certain cytoskeletal proteins, such as fodrin (a spectrin-like molecule), are known to play an important role in the regulation of CD45's PTPase activity. In this study we mapped the fodrin binding domain of CD45 by deleting various portions of the cytoplasmic region, followed by the expression of these truncated cDNAs using an in vitro transcription/translation system. The results of these experiments indicate that the CD45 fodrin binding domain resides between amino acids 825 and 939. Construction of a fusion protein encoding the region between amino acids 825 and 939 shows that this particular sequence itself is sufficient for fodrin binding. Further analyses indicate that the sequence (930EENKKKNRN939S) in CD45 has good sequence homology with the spectrin binding domain found in the MSP1 glycoprotein of the malarial parasite. Biochemical studies, using binding competition assays, and a synthetic peptide containing the sequence 930EENKKKNRN939S, support the conclusion that the sequence between amino acids 930 and 939 is a critical part of CD45's fodrin binding domain. Further analyses indicate that this sequence is also involved in the fodrin-induced up-regulation of CD45 PTPase activity. Therefore, we suggest that fodrin binding to this domain is required for the onset of CD45-mediated signal transduction and leukocyte activation.
Early transformative changes in normal ovarian surface epithelium induced by oxidative stress require Akt upregulation, DNA damage and epithelial–stromal interaction (2013)

Ovarian cancer is the deadliest gynecological malignancy due to detection of cancer at a late stage when the disease has metastasized. One likely progenitor cell type of ovarian cancer is the ovarian surface epithelium (OSE), which proliferates rapidly in the presence of inflammatory cytokines and oxidative stress following ovulation. To determine whether oxidative stress induces DNA damage leading to spontaneous transformative changes in normal OSE, an immortalized mouse OSE cell line (MOSE cells) or normal mouse ovarian organoids were treated with hydrogen peroxide (H2O2) and loss of contact inhibition was assessed by soft agar assay. In response to H2O2, OSE cells grown in 3D exhibited growth in soft agar but MOSE cells grown on 2D plastic did not, indicating a critical role for epithelial-stromal interactions in neoplastic initiation. Loss of contact inhibition in response to H2O2 correlated with an increase in proliferation, DNA damage and upregulation of the oncogene Akt1. Use of a reactive oxygen species scavenger or Akt inhibitor blocked H2O2-induced proliferation and growth in soft agar. Although parental MOSE cells did not undergo transformation by H2O2, MOSE cells stably overexpressing constitutively active myristoylated Akt or knockdown of phosphatase and tensin homolog (PTEN) exhibited loss of contact inhibition and increased proliferation. This study indicates that normal OSE undergo transformative changes induced by oxidative stress and that this process requires Akt upregulation and activation. A 3D model that retains tissue architecture is critical for studying this process and may lead to development of new intervention strategies directed at early stages of ovarian cancer.
Evaluation of Eustasy, Subsidence, and Sediment Input as Controls on Depositional Sequence Geometries and the Synchroneity of Sequence Boundaries (1993)

Applying depositional sequence stratigraphic concepts to the interpretation of siliciclastic depositional systems is becoming an increasingly important tool in petroleum geology. After a succession of breakthroughs during the 1970s and 1980s, sequence stratigraphic concepts now have entered a phase of intense application and documentation, especially with regard to successful implementation in the field of petroleum geology. Workers have applied these concepts to a variety of databases, ranging from outcrop to cores to electric logs and to multifold seismic data. Clearly, sequence stratigraphic concepts embody–not a rigid model or template–but rather a way of looking at geology. This volume has two purposes: to compile some recent applications of siliciclastic sequence stratigraphic concepts, and to present new studies focused on refining conceptual models. This memoir grew out of a 1991 symposium, "Variations in Depositional Systems Within a Sequence Stratigraphic Framework: Applications to Exploration," organized by the authors at the AAPG annual meeting at Dallas. Robert Loucks and Rick Sarg have edited a companion volume, also published by AAPG,"Entitled Carbonate Sequence Stratigraphy: New Developments and Applications."
Substance P primes the formation of hydrogen peroxide and nitric oxide in human neutrophils (1999)

Substance P (SP), a neurotransmitter of the central and peripheral nervous system, has been implicated as a mediator of the pulmonary inflammatory response through its stimulatory effects on neutrophils. We investigated the role of SP in priming the production of reactive oxygen species by human neutrophils with the cytochrome c reduction assay and by flow cytometry using the intracellular oxidizable probe dichlorofluorescein. We also investigated SP-induced formation of nitrite and nitrate as an index of nitric oxide (NO) production. Our results indicate that SP primes two distinct pathways with respect to the induction of reactive oxygen species in the human neutrophil: the production of superoxide anion and hydrogen peroxide by the calmodulin-dependent NADPH oxidase, and the generation of NO by a constitutive NO synthase. Preincubation of neutrophils with inhibitors of calmodulin and NO synthase diminished the oxidative response in an additive fashion. These results give insight into distinct signal transduction pathways in the SP-primed neutrophil with respect to the formation of superoxide anion, hydrogen peroxide, and NO.
VMInsight: Hardware Virtualization-Based Process Security Monitoring System (2011)

Malicious software is one of the primary threats to information system on Internet, while the traditional host-based and network-based monitoring systems are vulnerable to prevent the malicious behavior of software because most current malicious software is capable of resisting security monitoring. Virtualization technology gives an impactful approach to monitoring the behavior of malicious software since it can provide an abstraction layer between the operating system and the hardware. In this paper, we propose a hardware-virtualization-based security monitor system named VMInsight, which can provide load-time and run-time monitoring for processes. VMInsight intercepts system calls and process behaviors by monitoring changes in the virtual machine CPU register, and it is implemented in the hyper visor, thus is completely transparent to the software and operating system running in the virtual machine. The experimental results show that the performance overhead of VMInsight is less than 10%, and it can be easily applied to the third-party security monitoring system.
Social Media-based Profiling of Business Locations (2014)

We present a method for profiling businesses at specific locations that is based on mining information from social media. The method matches geo-tagged tweets from Twitter against venues from Foursquare to identify the specific business mentioned in a tweet. By linking geo-coordinates to places, the tweets associated with a business, such as a store, can then be used to profile that business. We used a sentiment estimator developed for tweets to create sentiment profiles of the stores in a chain, computing the average sentiment of tweets associated with each store. We present the results as heatmaps which show how sentiment differs across stores in the same chain and how some chains have more positive sentiment than other chains. We also created profiles of social group size for businesses and show sample heatmaps illustrating how the size of a social group can vary.
Investigation of atmospheric insect wing-beat frequencies and iridescence features using a multi-spectral kHz remote detection system (2014)

Quantitative investigation of insect activity in their natural habitat is a challenging task for entomologist. It is difficult to address questions such as flight direction, predation strength and overall activities using the current techniques such as traps and sweep nets. A multi-spectral kHz remote detection system using sunlight as an illumination source is presented. We explore possibilities of remote optical classification of insects based on their wing-beat frequencies and iridescence features. It is shown that the wing-beat frequency of the fast insect events can be resolved by implementing high sampling frequency. The iridescence features generated from the change of color in two channels (visible and near infrared) during wing-beat cycle is presented. We show that the shape of the wing-beat trajectory is different for different insects. The flight direction of atmospheric insect is also determined using silicon quadrant detector.
Heat transfer from micro-finned and flat surfaces to flow of Fluorinert coolant; boiling heat transfer (2002)

This paper reports the data of forced convection boiling heat transfer from a 2 cm/spl times/2 cm simulated chip to a fluorocarbon coolant (FX3250) in a parallel-plate channel. The experimental parameters were the channel height (1 and 5 mm), the simulated chip surface (flat and micro-finned), and the coolant velocity (0.125-4 m/s). The effectiveness of longitudinal micro-fins (0.5 mm high/spl times/0.5 mm wide) in heat transfer enhancement was studied. The experimental results suggest that, in narrow channels, a phenomenon known as "slugging" could cause boiling crisis at low heat flux. Also, the effect of foreign gas could be diminished in narrow channels.
Joint Particle Filter and UKF Position Tracking in Severe Non-Line-of-Sight Situations (2009)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> The performance of localization techniques in a wireless communication system is severely impaired by biases induced in the range and angle measures because of the non-line-of-sight (NLOS) situation, caused by obstacles in the transmitted signal path. However, the knowledge of the line-of-sight (LOS) or NLOS situation for each measure can improve the final accuracy. This paper studies the localization of mobile terminals (MT) based on a Bayesian model for the LOS-NLOS evolution. This Bayesian model does not require having a minimum number of LOS measures at each acquisition. A tracking strategy based on a particle filter (PF) and an unscented Kalman filter (UKF) is used both to estimate the LOS-NLOS situation and the MT kinetic variables (position and speed). The approach shows a remarkable reduction in positioning error and a high degree of scalability in terms of performance versus complexity. </para>
