A server- and browser-transparent CSRF defense for web 2.0 applications (2011)

Cross-Site Request Forgery (CSRF) vulnerabilities constitute one of the most serious web application vulnerabilities, ranking fourth in the CWE/SANS Top 25 Most Dangerous Software Errors. By exploiting this vulnerability, an attacker can submit requests to a web application using a victim user's credentials. A successful attack can lead to compromised accounts, stolen bank funds or information leaks. This paper presents a new server-side defense against CSRF attacks. Our solution, called jCSRF, operates as a serverside proxy, and does not require any server or browser modifications. Thus, it can be deployed by a site administrator without requiring access to web application source code, or the need to understand it. Moreover, protection is achieved without requiring web-site users to make use of a specific browser or a browser plug-in. Unlike previous server-side solutions, jCSRF addresses two key aspects of Web 2.0: extensive use of client-side scripts that can create requests to URLs that do not appear in the HTML page returned to the client; and services provided by two or more collaborating web sites that need to make cross-domain requests.

Amino Acid‐Based Dendrimers (2011)

In this chapter we briefly discuss the synthetic strategies of some representative peptide dendrimers. We then focus on various recent efforts of using designed peptide dendrimers as potential vaccines, antimicrobial agents, protein/enzyme mimics, metal ion sensors, magnetic resonance imaging contrast agents, DNA/RNA delivery vectors, affinity purification ligands, or biomedical sealant materials. Further explorations on this unique class of interesting molecules are required for additional potential applications.
Effects of Low Irradiance Stress on Gibberellin Levels in Pea Seedlings (1995)

Using gas chromatography-selected ion monitoring with internal standards we analyzed endogenous levels of GA1, GA8, GA19, GA20, GA29, GA44 and GA53 in shoots of pea cv. Alaska grown under different levels of irradiance: high irradiance, 386±70μmol m-2s-1, control (100%); medium (50%); low (10%); darkness (0%). The average plant heights for medium and low irradiance and dark grown plants were 157%, 275%, and 460% of the control plants, respectively. Plants grown in medium and low irradiance developed the same numbers of internodes as control plants but plants in darkness developed fewer internodes and exhibited suppressed leaf expansion. The endogenous levels of GA1 GA8 and GA29 were higher in medium and low irradiance grown plants than those of the high irradiance control. In particular, the GA20 level of low irradiance plants was markedly higher (7.6-fold) than that of control plants. In dark-grown plants GA1, and GA8 levels also slightly increased but GA20 and GA29 levels decreased and the levels of GA19, GA44 and GA53 did not change. Feeding of GA1, and a GA biosynthesis inhibitor (uniconazole) to plants grown at reduced irradiance and in darkness suggests that the responsiveness of plants to GA1, also increased at low irradiance and in darkness. In conclusion, plants increase both GA1, and GA20 biosynthesis or altered catabolism and GA1, responsiveness under low irradiance stress
Navigation with place representations and visible landmarks (2004)

Existing navigation techniques do not scale well to large virtual worlds. We present a new technique, navigation with place representations and visible landmarks that scales from town-sized to planet-sized worlds. Visible landmarks make distant landmarks visible and allow users to travel relative to those landmarks with a single gesture. Actual and symbolic place representations allow users to detect and travel to more distant locations with a small number of gestures. The world's semantic place hierarchy determines which visible landmarks and place representations users can see at any point in time. We present experimental results demonstrating that our technique allows users to navigate more efficiently than a modified panning and zooming W1M, completing within-place navigation tasks 22% faster and between-place tasks 38% faster on average.
Evaluation of a potential non‐leaching biocide using the marine fouling diatom<i>Amphora coffeaeformis</i> (1993)

The toxicity and degree of leaching of the antimicrobial agent 3‐(trimethoxysily)‐propyloctadecyldimethyl ammonium chloride (Dow Corning® 5700) on coated surfaces has been studied using the test alga Amphora coffeaeformis. Cell viability studies indicated a toxic effect of DC5700‐coated surfaces compared to the controls. Leaching coated surfaces in seawater reduced their toxicity to adhered cells. After 7 d, DC5700 leachates caused significant effects on cell growth although consecutive leaching for further 7 d periods produced leachates with no significant effects on the cells compared to the controls. The extraction and gas Chromatographic separation of leachate samples showed the presence of volatile components of DC5700. The results show the toxicity of the biocide to the test alga but since leaching removed the DC5700 from the surfaces, an alternative bonding system would be necessary in order for it to be used as a non‐leaching biocide.
A photoacoustics based continuous non-invasive blood glucose monitoring system (2015)

The paper examines the use of photoacoustic spectroscopy (PAS) for making continuous non-invasive blood glucose measurements. An apparatus for performing photoacoustic (PA) measurements is constructed and the technique is verified in vitro and in vivo through measurements on glucose solutions and live tissue. The signal amplitude is observed to increase with the glucose concentration in both cases. A linear calibration method is applied on each individual to obtain a glucose concentration value from each PA measurement. The glucose values obtained are compared with reference glucose concentrations measured using a standard glucose meter, giving a mean absolute difference (MAD) of 23.75 mg/dl and a mean absolute relative difference (MARD) of 18.03%. A plot of 196 measurement pairs taken over 30 normal subjects on a Clarke Error Grid gives a point distribution of 67.86%, 31.12%, 0.0%, 1.02% and 0.0% over zones A to E of the grid. This performance is an improvement over those obtained previously using PAS and point to the potential of the technique for non-invasive glucose measurements. An FPGA based reconfigurable embedded architecture is proposed for high speed data acquisition, noise reduction and display of PA measurements. The architecture operates at 274.823 MHz on a Xilinx Virtex-II Pro FPGA providing an SNR improvement of 30 dB and enabling a portable blood glucose monitoring system.
Growth and characterization of a cell line from a human primary neuroendocrine carcinoma of the skin (Merkel cell carcinoma) in culture and as xenograft (2001)

The primary neuroendocrine carcinoma of the skin or Merkel cell carcinoma (MCC) is a skin tumor with aggressive biological behaviour. Experimental models for investigating the biological properties of the tumor are prerequisite for developing new therapeutic approaches. In this study, we report the establishment and characterisation of a cell line derived from the lymph-node metastasis of a patient with highly aggressive MCC. Merkel carcinoma cells (MCC-1) grew as floating aggregates in suspension cultures for more than two years and over 70 subcultures. The proliferation rate in suspension cultures was rather moderate with a population doubling time of 69 h. The immunocytochemical pattern of the cultured MCC-1 was similar to that of the original tumor with expression of cytokeratin 18, neuron-specific enolase, neurofilaments, and synaptophysin. In addition, reverse transcriptase polymerase chain reaction (RT-PCR) revealed presence of chromogranin A mRNA in the MCC-1 cell line. Furthermore, electron microscopy yielded the rare finding of neuroendocrine granules in the cytoplasm of the cultured cells. The cell line MCC-1 was able to form colonies in soft agar. Nude mice developed solid tumors with similar histology to the original tumor after subcutaneous and intravenous injections of cultured MCC-1, and malignant ascites was seen after intraperitoneal injection. Also, two MCC-1 sublines were established by reculturing cells from the xenografts grown in vivo and immunocytochemistry confirmed their neuroendocrine origin. The MCC-1 line may thus serve as a model for studying the biology and the metastatic potential of Merkel cell carcinoma.
Ph1+bcr- acute leukemias: implication of Alu sequences in a chromosomal translocation occurring in the new cluster region within the BCR gene. (1989)

Chromosomal breakpoints on chromosome 22 are located in the first intron of the bcr gene in half of the Philadelphia-positive acute leukemias (Ph1+bcr- AL). We have previously shown that, in these cases, the breakpoints are clustered in the 3' portion of the bcr gene first intron, particularly in a region called bcr2 or m-bcr-1. In order to search for mechanisms underlying the reciprocal chromosome translocation, molecular analysis of breakpoints on chromosome 9 and 22 were performed in a Ph1+bcr- acute lymphoblastic leukemia with bcr2 rearrangement. The comparison of rearranged sequences with their normal counterparts showed that human repetitive Alu sequences were physically linked to the translocation on both chromosomes. In addition an inverted Alu repeat was found 5' to each rearranged Alu sequence on chromosome 22 and 9, with an intervening sequence of 210 and 90bp respectively. This allows to propose a new model, still to be confirmed, of recombination after formation of two hairpin structures which could facilitate the genesis of the chromosomal accident.
Robust Model-Aided Inertial Localization for Autonomous Underwater Vehicles (2018)

This paper presents a manifold based Unscented Kalman Filter that applies a novel strategy for inertial, model-aiding and Acoustic Doppler Current Profiler (ADCP) measurement incorporation. The filter is capable of observing and utilizing the Earth rotation for heading estimation with a tactical grade IMU, and utilizes information from the vehicle model during DVL drop outs. The drag and thrust model-aiding accounts for the correlated nature of vehicle model parameter error by applying them as states in the filter. ADCP-aiding provides further information for the model-aiding in the case of DVL bottom-lock loss. Additionally this work was implemented using the MTK and ROCK framework in C++, and is capable of running in real-time on computing available on the FlatFish AUV. The IMU biases are estimated in a fully coupled approach in the navigation filter. Heading convergence is shown on a real-world data set. Further experiments show that the filter is capable of consistent positioning, and data denial validates the method for DVL dropouts due to very low or high altitude scenarios.
Development of an Active Fault-Tolerant Flight Control Strategy (2008)

This paper discusses the design of an active fault-tolerant flight control strategy for improvement of the operational control capability of the aircraft system. The research work draws expertise from actions undertaken within the European Flight Mechanics Action Group [FM-AG(16)] on fault-tolerant control, which develops a collaborative effort in Europe to create new fault-tolerant control technologies that significantly advance the goals of the aviation safety. The methodology is applied to a trimmable horizontal stabilizer runaway fault occurring in a large transport aircraft. The goal is to provide a self-repairing capability to enable the pilot to land the aircraft safely. The fault-tolerant control strategy works in such a way that once the fault is detected by the fault detection and isolation unit, a compensation loop is activated for safe recovery. A key feature of the proposed strategy is that the design of the fault-tolerant control loop is done independently of the nominal autopilot and the nominal flight control system in place. Nonlinear simulation results demonstrate the effectiveness of the proposed fault-tolerant control scheme.
Development of Corrosion Resistant Brazing Sheet for Drawn Cup Type Evaporators Part I: Alloy Development (1993)

<div class="htmlview paragraph">Extensive work was conducted to develop a corrosion resistant brazing sheet alloy and to apply it to a drawn cup type evaporator in automotive air conditioning system. The items to be investigated included the influence of chemical composition of the core alloy on corrosion resistance, suppression of erosion during the brazing cycle, and enhancement of the brazing sheet formability. Additional investigation was conducted to develop a new corrosion test method on the basis of better understanding of the mechanism of corrosion in the field and to evaluate the corrosion resistance of a evaporator fabricated from the new alloy. This paper, as Part 1, describes the results of alloy development from the metallurgical and electrochemical point of view.</div>
Scalable Name Lookup in NDN Using Effective Name Component Encoding (2012)

Name-based route lookup is a key function for Named Data Networking (NDN). The NDN names are hierarchical and have variable and unbounded lengths, which are much longer than IPv4/6 address, making fast name lookup a challenging issue. In this paper, we propose an effective Name Component Encoding (NCE) solution with the following two techniques: (1) A code allocation mechanism is developed to achieve memory-efficient encoding for name components, (2) We apply an improved State Transition Arrays to accelerate the longest name prefix matching and design a fast and incremental update mechanism which satisfies the special requirements of NDN forwarding process, namely to insert, modify, and delete name prefixes frequently. Furthermore, we analyze the memory consumption and time complexity of NCE. Experimental results on a name set containing 3,000,000 names demonstrate that compared with the character trie NCE reduces overall 30% memory. Besides, NCE performs a few millions lookups per second (on an Intel 2.8 GHz CPU), a speedup of over 7 times compared with the character trie. Our evaluation results also show that NCE can scale up to accommodate the potential future growth of the name sets.
Temporal Processing of dynamic positron emission tomography via principal component analysis in the sinogram domain (2004)

In this paper, we compare various temporal analysis schemes applied to dynamic PET for improved quantification, image quality and temporal compression purposes. We compare an optimal sampling schedule (OSS) design, principal component analysis (PCA) applied in the image domain, and principal component analysis applied in the sinogram domain; for region-of-interest quantification, sinogram-domain PCA is combined with the Huesman algorithm to quantify from the sinograms directly without requiring reconstruction of all PCA channels. Using a simulated phantom FDG brain study and three clinical studies, we evaluate the fidelity of the compressed data for estimation of local cerebral metabolic rate of glucose by a four-compartment model. Our results show that using a noise-normalized PCA in the sinogram domain gives similar compression ratio and quantitative accuracy to OSS, but with substantially better precision. These results indicate that sinogram-domain PCA for dynamic PET can be a useful preprocessing stage for PET compression and quantification applications.

Tunneling injection lasers: a new class of lasers with reduced hot carrier effects (1996)

In conventional quantum-well lasers, carriers are injected into the quantum wells with quite high energies. We have investigated quantum-well lasers in which electrons are injected into the quantum-well ground state through tunneling. The tunneling injection lasers are shown to have negligible gain compression, superior high-temperature performance, lower Auger recombination and wavelength chirp, and better modulation characteristics when compared to conventional lasers. The underlying physical principles behind the superior performance are also explored, and calculations and measurements of relaxation times in quantum wells have been made. Experimental results are presented for lasers made with a variety of material systems, InGaAs-GaAs-AlGaAs, InGaAs-GaAs-InGaAsP-InGaP, and InGaAs-InGaAsP-InP, for different applications. Both single quantum-well and multiple quantum-well tunneling injection lasers are demonstrated.
A Statistical Inference Technique for GPS Interference Detection (2009)

Narrowband interference can severely degrade the performance of GPS receivers. Detecting the interference and then characterizing it can lead to its removal. Knowledge that can be useful is the location of the source or direction of arrival of the interference (spatial-directional characteristics) and/or the time specification, frequency, and power of the interference (temporal-spectral characteristics). This work focuses on the second type. In previous work power spectral density fluctuation detection technique has been introduced [1], and statistical inference has been used to detect narrowband CW interference in the GPS signal band after being captured by the RF front end. In this technique, an assessment window of data is first divided into blocks and then analyzed to obtain the statistical parameters of the signal without interference. Then presence of interference is tested by comparing these parameters as a null hypothesis with the parameters extracted from a later window. The effect of the assessment window size on the level of confidence of this test has been already analyzed also in [1]. In this paper, using properties of the fast Fourier transform (FFT) and the effects of the number of FFT points on the test statistic mean and variance, we show that an appropriate data block size (for a specific window size) can be selected to achieve an optimum solution to detect "minimum power detectable interference." The algorithm to find the optimal solution is introduced. The theoretical result is supported by real experiments. Finally this algorithm is employed to detect a real GPS interference signal generated by a TV transmitter in Sydney, Australia.
Online rapid sampling microdialysis (rsMD) using enzyme-based electroanalysis for dynamic detection of ischaemia during free flap reconstructive surgery (2013)

We describe an enzyme-based electroanalysis system for real-time analysis of a clinical microdialysis sampling stream during surgery. Free flap tissue transfer is used widely in reconstructive surgery after resection of tumours or in other situations such as following major trauma. However, there is a risk of flap failure, due to thrombosis in the flap pedicle, leading to tissue ischaemia. Conventional clinical assessment is particularly difficult in such 'buried' flaps where access to the tissue is limited. Rapid sampling microdialysis (rsMD) is an enzyme-based electrochemical detection method, which is particularly suited to monitoring metabolism. This online flow injection system analyses a dialysate flow stream from an implanted microdialysis probe every 30 s for levels of glucose and lactate. Here, we report its first use in the monitoring of free flap reconstructive surgery, from flap detachment to re-vascularisation and overnight in the intensive care unit. The on-set of ischaemia by both arterial clamping and failure of venous drainage was seen as an increase in lactate and decrease in glucose levels. Glucose levels returned to normal within 10 min of successful arterial anastomosis, whilst lactate took longer to clear. The use of the lactate/glucose ratio provides a clear predictor of ischaemia on-set and subsequent recovery, as it is insensitive to changes in blood flow such as those caused by topical vasodilators, like papaverine. The use of storage tubing to preserve the time course of dialysate, when technical difficulties arise, until offline analysis can occur, is also shown. The potential use of rsMD in free flap surgery and tissue monitoring is highly promising.
MEMS-based thermal management of high heat flux devices for integrated cooling of electronics (2004)

This paper describes the development of EDIFICE: Embedded Droplet Impingement For Integrated Cooling of Electronics. The EDIFICE project seeks to develop an integrated droplet impingement cooling device for removing chip heat fluxes over 100 W/cm/sup 2/, employing latent heat of vaporization of dielectric fluids. Micro-spray nozzles are fabricated to produce 50-100 micron droplets coupled with surface texturing on the backside of the chip to promote spreading and boiling. A novel features to enable adaptive on-demand cooling is MEMS sensing and MEMS actuation. EDIFICE is integrated within the electronics package and fabricated using advanced micromanfacturing technologies.
Optical absorbance of silver ellipsoidal particles (1987)

We describe a simple technique for producing arrays of silver ellipsoidal particles with parallel principal axes. The optical absorbance of the silver ellipsoids produced by this technique was measured as a function of angle, polarization, and wavelength of the incident light. Calculations of the optical absorbance were made using nonretarded electrodynamics and the bulk optical constants for silver. The results of these calculations are shown to compare favorably with the experimentally observed absorbance.
The Adolescent Outcome of Hyperactive Children Diagnosed By Research Criteria—III. Mother–Child Interactions, Family Conflicts and Maternal Psychopathology (1991)

The present study reports the results of a prospective, 8-year follow-up study of 100 hyperactive and 60 normal children followed from childhood into adolescence. Ratings of child behavior problems and family conflicts as well as direct observations of mother-child interactions were taken in childhood and again at adolescent follow-up. At outcome, hyperactives continued to have more conduct and learning problems and to be more hyperactive, inattentive, and impulsive than controls. Hyperactives were also rated by their mothers as having more numerous and intense family conflicts than the normal controls, although the adolescents in both groups did not differ in their own ratings of these conflicts. Observations of mother-adolescent interactions at outcome found the hyperactive dyads displaying more negative and controlling behaviors and less positive and facilitating behaviors towards each other than in the normal dyads. These interaction patterns were significantly related to similar patterns in mother-child interactions observed 8 years earlier. Mothers of hyperactives also reported more personal psychological distress than normal mothers at outcome. Further analyses of subgroups of hyperactives at outcome, formed on the presence or absence of ADHD and oppositional defiant disorder (ODD), indicated that the presence of ODD accounted for most of the differences between hyperactives and normals on the interaction measures, ratings of home conflicts, and ratings of maternal psychological distress. Results suggest that the development and maintenance of ODD into adolescence in hyperactive children is strongly associated with aggression and negative parent-child interactions in childhood.
