Detecting GNSS Spoofing using a Network of Hardware Oscillators (2016)

In the face of growing concern about spoofing attacks on GNSS transmissions, we propose a scheme to cross validate GNSS based timing against intrinsic properties of local hardware oscillators. We demonstrate our approach as being able to detect certain types of spoofing attacks on the timing reference signal using an ensemble detector test-bed currently in development. Our primary contribution is a linear belief filter applied to a set of low-cost oscillators, organized in a maximum likelihood clock ensemble. Our approach is intended to improve the sensitivity of conventional threshold based detectors that compare time offset between the GNSS stabilized reference and a local free running detector clock to detect changes in offset or slew rate.

Microfiltration of Butter Serum Upon Casein Micelle Destabilization (2006)

The gross composition of butter serum, the aqueous phase of butter, is comparable to that of buttermilk, except that it has a higher content of material derived from the milk fat globule membrane (MFGM). As such, butter serum is a good source for further purification of MFGM material. The purified fraction could be of interest for its emulsifying and nutritional properties. The effect of sodium citrate and ethanol on the dissociation of butter serum casein micelles, and their effect on casein retention upon tangential microfiltration were investigated. Optimal conditions of casein micelle dissociation were assessed by using an experimental design (response surface full central composite orthogonal design) with temperature and ethanol or sodium citrate concentration as design variables and the Hunter L* value as response variable. For both dissociating agents, a highly significant reduced quadratic model was fit to the data. Microfiltration tests were performed on pure butter serum, and on butter serum in the presence of sodium citrate, under optimal dissociation conditions (50 degrees C, 80 mM). A cellulose acetate membrane with a pore size of 0.15 microm was used. From the filtration curves and fouling coefficients it was clear that the addition of sodium citrate improved the permeation flux, and minimized fouling. All fractions were analyzed for dry matter, protein, lactose, lipid, and polar lipid contents. The protein fraction was further characterized by sodium dodecyl sulfate-PAGE. It was shown that sodium citrate greatly enhanced casein transmission through the membrane, but at the expense of substantial losses of polar lipids.

RNN Fisher Vectors for Action Recognition and Image Annotation (2015)

Recurrent Neural Networks (RNNs) have had considerable success in classifying and predicting sequences. We demonstrate that RNNs can be effectively used in order to encode sequences and provide effective representations. The methodology we use is based on Fisher Vectors, where the RNNs are the generative probabilistic models and the partial derivatives are computed using backpropagation. State of the art results are obtained in two central but distant tasks, which both rely on sequences: video action recognition and image annotation. We also show a surprising transfer learning result from the task of image annotation to the task of video action recognition.

On the linear fractional shift invariant systems associated with fractional Fourier transform (2011)

The fractional Fourier transform (FRFT) has been shown to be a powerful analyzing tool in signal processing. Many properties of this transform have been currently derived as counterparts to the corresponding properties of the Fourier transform (FT), including the theory of the linear fractional shift invariant (LFSI) systems. However, the LFSI systems, which are derived as extensions of the linear time invariant (LTI) systems, available in the literature do not generalize very nicely the LTI systems, which state that the output of a LTI system does not depend on the particular time the input is applied, and the FT of the output is the product of the transfer function and the FT of the input in the Fourier domain. In this paper, we propose a new LFSI system structure associated with the FRFT, and the LTI systems are noted as special cases. The eigenfunctions and eigenvalues of the new LFSI systems are presented. Moreover, the conditions for distortionless transmission in the fractional Fourier domain and basic properties of the ideal fractional filter are derived. Some applications of the achieved results are also discussed.
Mesoporous separation membranes of {[Cu(BTC–H2)2·(H2O)2]·3H2O} nanobelts synthesized by ultrasonication at room temperature (2012)

Copper and 1,3,5-benzenetricarboxylic acid complex {[Cu(BTC–H2)2·(H2O)2]·3H2O} nanobelts were successfully prepared in aqueous solution at low temperature by mixing ultra-thin, highly positively charged copper hydroxide nanostrands with 1,3,5-benzenetricarboxylic acid for the first time. These nanobelts have a thickness of about 15 nm, width of 200–300 nm, and length of several micrometers. We found that the copper hydroxide nanostrands play the key role for the formation of these nanobelts. The effects of the synthesis parameters were investigated in detail. Due to their thin thickness, high aspect ratio and nice dispersion in solution, these {[Cu(BTC–H2)2·(H2O)2]·3H2O} nanobelts were successfully assembled into mesoporous membranes by filtration techniques. These {[Cu(BTC–H2)2·(H2O)2]·3H2O} nanobelts membranes demonstrated 96% rejection for 5 nm nanoparticles with flux of 4506 L m−2 h−1 bar−1 and were stable at pH 3. The separation performance of these membranes is 5 to 10 times higher than that of the commercial membranes with similar rejections. This method may provide a method for the synthesis of metal–organic complex nanostructures by using metal hydroxide nanostrands as precursors and extend their application for nanoparticle separation from water.
Metabotropic glutamate receptors, transmitter output and fatty acids: studies in rat brain slices (1996)

1. The effects of (1S,3R)-1-aminocyclopentane-1,3-dicarboxylic acid (1S,3R-ACPD), a non-selective agonist of the metabotropic glutamate receptors (mGluRs), have been studied in rat cortical and striatal slices by measuring the depolarization-induced output of D-[3H]-aspartate (D-[3H]-Asp) and of [3H]-glutamate ([3H]-Glu), neosynthesized from [3H]-glutamine. 2. In cortical slices, 1S,3R-ACPD potentiated the depolarization-induced (KCl, 30 mM) output of both D-[3H]-Asp and [3H]-Glu. The potentiation, obtained at 300 microM 1S,3R-ACPD was 65 +/- 6% for D-[3H]-Asp and 56 +/- 10% for [3H]-Glu. Conversely, in striatal slices, 1S,3R-ACPD reduced the depolarization-induced transmitter output. The reduction, obtained at 300 microM of the agonist, was 60 +/- 8% for D-[3H]-Asp and 50 +/- 5% for neosynthesized [3H]-Glu. 3. Bovine serum albumin (BSA, 15 microM), which is able to bind locally produced fatty acids, completely eliminated the potentiating effect 1S,3R-ACPD had on D-[3H]-Asp output from cortical slices. Low concentrations of arachidonic acid (1-10 microM) or of oleic acid (1-10 microM) added to BSA-containing perfusion medium, restored this potentiating effect. BSA, however, had no effect on the inhibitory action of 1S,3R-ACPD in striatal slices. 4. Bromophenacyl bromide (100 microM), an inhibitor of phospholipase A2, and RG80267 (100 microM), an inhibitor of diacylglycerol lipase, have been shown to inhibit fatty acid production. These compounds prevented the potentiating effect of 1S,3R-ACPD on D-[3H]-Asp-output in cortical slices. 5. Indomethacin (100 microM), an inhibitor of cyclo-oxygenases, plus nordihydroguaiaretic acid (100 microM), an inhibitor of lipoxygenases, increased D-[3H]-Asp output in cortical slices perfused with BSA-containing medium. 6. These experiments suggest that the mGluR-mediated potentiation of transmitter output requires the availability of unsaturated fatty acids, such as arachidonic or oleic acids, in cortical slices. In contrast, the mGluR-induced inhibition of transmitter output is not dependent upon fatty acid availability in striatal slices. The requirement of both unsaturated fatty acids and 1S,3R-ACPD in the facilitation of transmitter exocytosis may play an important role in the regulation of synaptic plasticity.

A system‐level model for the microbial regulatory genome (2014)

Microbes can tailor transcriptional responses to diverse environmental challenges despite having streamlined genomes and a limited number of regulators. Here, we present data-driven models that capture the dynamic interplay of the environment and genome-encoded regulatory programs of two types of prokaryotes: Escherichia coli (a bacterium) and Halobacterium salinarum (an archaeon). The models reveal how the genome-wide distributions of cis-acting gene regulatory elements and the conditional influences of transcription factors at each of those elements encode programs for eliciting a wide array of environment-specific responses. We demonstrate how these programs partition transcriptional regulation of genes within regulons and operons to re-organize gene-gene functional associations in each environment. The models capture fitness-relevant co-regulation by different transcriptional control mechanisms acting across the entire genome, to define a generalized, system-level organizing principle for prokaryotic gene regulatory networks that goes well beyond existing paradigms of gene regulation. An online resource (http://egrin2.systemsbiology.net) has been developed to facilitate multiscale exploration of conditional gene regulation in the two prokaryotes.
Spallation of a substrate by thermal shock and thermal expansion differential during splat cooling (2002)

The manufacture of metal–matrix composite materials by spray deposition is a very attractive process, but impaired by the spallation that may take place after impact of molten metal droplets on the fibers. In this work, the spallation of a quartz substrate was investigated through video and acoustic measurements and through temperature measurements of the splat surface. The time scales pertaining to the fracture mechanisms are examined from acoustic measurements of the spallation. The spall formation mechanism was quantified by analyzing the geometric configuration of the splats and spalls under varying conditions of droplet superheat, droplet size, and droplet or substrate material. Furthermore, the thermal contact resistance between the splat and the substrate was evaluated by matching the measured temperatures of the top or bottom surface of the splat with numerical results from a heat conduction model with phase change.
Heuristic route planning: an application to fighter aircraft (2003)

A route-planner system prototype is described that finds an optimal or near-optimal path for survivable low-level penetration through hostile enemy threats. The planner considers terrain and physical obstacles, threats, fuel constraints, time constraints, aircraft performance characteristics, and pilot input. The mission-level route planner generates a route that includes fuel and time requirements, distance, threat exposure, and metrics to indicate the quality of the path. This path is then passed to a tactical-level route planner that uses models of the ownship and threat capability to generate a detailed flyable route. The A* heuristic search algorithm was selected to determine the routes due to its flexibility and efficient use of computing resources. A route-planner development workstation is also described. This workstation is used to prototype heuristic evaluation functions for the A* algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
DFIG Based Wind Turbine Contribution to System Frequency Control (2011)

Abstract&#13;\nEnergy is one of the most important factors that continue to influence the shape of civilization in the 21st Century. The cost and availability of energy significantly impacts our quality of life, the health of national economies and the stability of our environment. In recent years there has been a significant global commitment to develop clean and alternative forms of energy resources and it is envisioned that by 2020 10% of world energy will be supplied from renewable resources, and there is an expectation that this value will grow to 50% by 2050.&#13;\nAmong renewable energy resources, wind generation technology has matured considerably, and wind is fairly distributed around the globe and therefore available to world communities. In the last decade, wind generation has been the fastest growing energy source globally. However more penetration of wind energy into existing power networks raises concern for power system operators and regulators. Traditionally wind energy convertors do not participate in frequency regulation or Automatic Generation Control (AGC) services, and therefore large penetration of wind power into the power systems can result in a reduction of total system inertia and robustness of the frequency response to the disturbances.&#13;\nThe research presented in this thesis covers some of the operational and design aspects of frequency control and AGC services in power systems with mixed generation resources. The thesis examines the operation of the Doubly Fed Induction Generator (DFIG) with a modified inertial loop control considering single-area and two-area frequency control, both primary control and AGC. The thesis presents new, small-perturbation, linear, dynamic, mathematical models for the simulation of primary regulation services and AGC services for single-area and two-area power systems with a mix of conventional and non-conventional DFIG-based wind generators. In order to improve the performance of the frequency regulation and AGC services of the above systems, a parameter optimization technique based on the minimization of the Integral of Squared Errors (ISE) is applied to determine the optimal settings for the proportional-integral (PI) controller gains of the DFIG machines.&#13;\nThe thesis presents analytical studies with various perturbations to demonstrate the effectiveness and participation of DFIG-based wind generators in frequency support services and draws some important conclusions. Variation in DFIG penetration levels, and wind speed levels (strong wind and weak wind) on system frequency control performance, has also been examined in the thesis.
New design and analysis of Bragg grating waveguides (2010)

New design of optical waveguides is presented to synthesize Bragg grating waveguides without inducing birefringence. In the design, waveguide core has a thin trench on the top surface of the core and width of the trench is modulated concurrently with width modulation of the waveguide core. Effective refractive index profiles in Bragg grating waveguides are obtained by a differential inverse scattering algorithm and converted to waveguide width profiles by using the new core design. This procedure allows design of non-birefringent Bragg grating waveguides on planar substrate. The method is applied to the design of chromatic dispersion compensators. For characterization of Bragg grating waveguides, analysis based on short-time Fourier transform of Bragg grating response waveforms is presented.
Temporal order of bipolar cell genesis in the neural retina (2008)

Using two independent in vivo methodologies in rat and mouse retina, we have demonstrated that there are distinct waves of genesis of the two major bipolar cell types, with cone bipolar genesis preceding rod bipolar genesis. These waves of bipolar genesis correspond to the order of genesis of the presynaptic photoreceptor cell types.
DNA-Modified Polysulphone Microspheres for Endocrine Disruptors and Heavy Metal Ions Removal (2005)

Porous polysulphone (PSf) microspheres were modified by blending DNA into them and immobilizing DNA onto their surfaces. The DNA-modified microspheres, which were stable in water, were then used to remove endocrine disruptors and heavy metal ions from their aqueous solutions. Such microspheres could effectively accumulate pollutant compounds and endocrine disruptors, such as ethidium bromide, Acridine Orange, biphenyl, dibenzofuran and dibenzo- p-dioxin from their aqueous solutions. PSf microspheres without DNA also accumulated and removed endocrine disruptors due to their porosity and the hydrophobic interaction between the endocrine disruptors and PSf. Endocrine disruptors with and without a planar structure were effectively accumulated and removed by the DNA-modified PSf microspheres. In addition, PSf microspheres were found to be capable of selectively removing heavy metal ions such as Zn 2+ , Cu 2+ , Mg 2+ , Cd 2+ and Ag + from their aqueous solutions. These results show that DNA can be used to modify PSf microspheres, with the DNA-modified microspheres having a potential use in environmental applications.

Synthesis of p-menthane derivatives with potential biological activity. (1988)

The synthesis of amino ketones and amino alcohols in p-menthane series is presented. These compounds were obtained in Mannich reaction, starting from the unsaturated ketone p-mentha-6,8-dien-2-one and its saturated analogue p-menthan-2-one. The structures of the compounds obtained were established by means of chemical transformations and elemental and spectral (IR, 1H NMR) analysis. The compounds obtained were subjected to the pharmacological investigations.
Cellular localization of the target structures recognized by the anti-Jo-1 antibody: immunofluorescence studies on cultured human myoblasts. (1991)

Antibodies to Jo-1 (alpha Jo-1) are most characteristically detected in patients with the idiopathic inflammatory muscle disease polymyositis (PM). The Jo-1 antigen has previously been identified as histidyl-tRNA synthetase (HRS). In order to clarify the cellular localization of the antigenic targets recognized by the alpha Jo-1 antibody, immunofluorescence (IF) studies were performed with cultured human myoblasts. Incubation with alpha Jo-1 positive sera demonstrated granular cytoplasmic as well as nuclear staining, but only the cytoplasmic fluorescence was specifically inhibited by preabsorbing the sera with recombinant histidyl-tRNA synthetase (rHRS). A polyclonal rabbit anti-rHRS sera demonstrated granular cytoplasmic IF which was also specifically inhibited by preincubation with rHRS protein. Alpha Jo-1 negative healthy control or patient sera demonstrated nonspecific low intensity staining. 35S methionine biosynthetically labelled myoblast cell extracts immunoprecipitated with alpha Jo-1 positive sera and analyzed by SDS-PAGE revealed a specific band of the same molecular weight as the rHRS antigen. Our studies demonstrate that alpha Jo-1 specifically binds to antigen in the cytoplasm of cultured myoblasts. Alpha Jo-1 has been shown to inhibit HRS activity in vitro. Given the importance of aminoacyl tRNA synthetases such as HRS to intracellular protein assembly, intracytoplasmic binding and enzyme inhibition in vivo may potentially contribute to the pathogenesis of autoimmune muscle damage in PM.
A robust framework for multiview age estimation (2010)

Age estimation from facial images has promising applications in human-computer interaction, biometrics, visual surveillance, and electronic customer relationship management, etc. Most existing techniques and systems can only handle frontal or near frontal view age estimation due to the difficulties of 1) differentiating diverse variations from uncontrollable and personalized aging patterns on faces and 2) collecting a fairly large database covering the chronometrical image series for each individual in different views. In this paper, we propose a robust framework to deal with multiview age estimation problem. A large face database, with significant age, pose, gender, and identity variations, is exploited in the experiments. In our framework, the training set is partitioned into small groups, namely code groups, according to their multiple labels, e.g. pose and age. Based on certain set-set distance measure, a compact representation for each image is obtained by measuring the distance between the image and all the code groups, which can be followed by classification or regression algorithms. Extensive experiments and comparisons with traditional multiview models demonstrate the proposed framework with significant advantages of variation decomposable, classifier adaptable, and feature selectable and extendable.
