Secure Sound Classification: Gaussian Mixture Models (2006)

We propose secure protocols for Gaussian mixture-based sound recognition. The protocols we describe allow varying levels of security between two collaborating parties. The case we examine consists of one party (Alice) providing data and other party (Bob) providing a recognition algorithm. We show that it is possible to have Bob apply his algorithm on Alice's data in such a way that the data and the recognition results will not be revealed to Bob thereby guaranteeing Alice's data privacy. Likewise we show that it is possible to organize the collaboration so that a reverse engineering of Bob's recognition algorithm cannot be performed by Alice. We show how Gaussian mixtures can be implemented in a secure manner using secure computation primitives implementing simple numerical operations and we demonstrate the process by showing how it can yield identical results to a non-secure computation while maintaining privacy
Solution and Micelle-Bound Structures of Tachyplesin I and Its Active Aromatic Linear Derivatives<sup>,</sup> (2002)

Tachyplesin I is a 17-residue peptide isolated from the horseshoe crab, Tachypleus tridentatus. It has high antimicrobial activity and adopts a beta-hairpin conformation in solution stabilized by two cross-strand disulfide bonds. We report an NMR structural investigation of wild-type tachyplesin I and three linear derivatives (denoted TPY4, TPF4, and TPA4 in which the bridging cysteine residues are uniformly replaced with tyrosine, phenylalanine, and alanine, respectively). The three-dimensional aqueous solution structures of the wild type and the active variant TPY4 reveal very similar beta-hairpin conformations. In contrast, the inactive variant TPA4 is unstructured in solution. The arrangement of the tyrosine side chains in the TPY4 structure suggests that the beta-hairpin is stabilized by aromatic ring stacking interactions. This is supported by experiments in which the beta-hairpin structure of TPF4 is disrupted by the addition of phenol, but not by the addition of an equimolar amount of cyclohexanol. We have also determined the structures of wild-type tachyplesin I and TPY4 in the presence of dodecylphosphocholine micelles. Both peptides undergo significant conformational rearrangement upon micelle association. Analysis of the micelle-associated peptide structures shows an increased level of exposure of specific hydrophobic side chains and an increased hydrophobic integy moment. Comparison of the structures in micelle and aqueous solution for both wild-type tachyplesin I and TPY4 reveals two requirements for high antimicrobial activity: a beta-hairpin fold in solution and the ability to rearrange critical side chain residues upon membrane association.
Impact of imperfect channel estimation on successive group interference cancellation techniques (2015)

In this paper we study the effect of the channel estimation error on the performance of successive group decoding (SGD) schemes. The contribution of this paper is to evaluate the performance of such systems in the interference MIMO channel environment. Precisely, we aim to assess the sensitivity of such decoding techniques to the imperfect estimation of the channel state information (CSI). The system reliability will be judged using the evaluation of bit error rate (BER) performance. The results of this paper clearly show the critical importance of the accuracy of channel estimation for the receive side group-based interference cancellation (SGIC) schemes.
Circulating Complement-C1q TNF-Related Protein 1 Levels Are Increased in Patients with Type 2 Diabetes and Are Associated with Insulin Sensitivity in Chinese Subjects (2014)

CTRP1 is a novel adipokine associated with T2DM in humans. The paradoxical increase of serum CTRP1 levels in T2DM subjects may be due to a compensatory response to the adverse glucose and lipid metabolism, which warrants further investigation.
Multiwavelength DFB laser arrays for optical network testbeds (1996)

We review the progress of multiwavelength DFB laser arrays made for optical network testbeds. The goal is to reduce the per-wavelength transmitter cost in manufacturing and network element control. Using photonic integration, we have addressed and resolved several important issues related to laser arrays such as wavelength accuracy, output power and optical packaging. State of the art results are summarized and its impact on the multiwavelength optical network is assessed.
USE OF 3,4-DIMETHOXYBENZYL GROUP AS A PROTECTING GROUP FOR THE 2′-HYDROXYL GROUP IN THE SYNTHESIS OF OLIGORIBONUCLEOTIDES (1986)

Abstract The 3,4-dimethoxybenzyl group was introduced to the 2′-hydroxyl group by the reaction of nucleosides with 3,4-dimethoxybenzyl trichloroacetimidate or 3,4-dimethoxybenzyl bromide-NaH. Further, this group can be used as a protecting group for the O6-amide group of the guanine residue. The protected nucleosides are useful starting materials for the synthesis of oligoribonucleotides. The 3,4-dimethoxybenzyl group was removed rapidly from the oligoribonucleotides by treatment with oxidizing agents without any damage to the glycosidic bonds.
Adsorption of Radon and Water Vapor on Commercial Activated Carbons (1995)

Abstract Equilibrium adsorption isotherms are reported for radon and water vapor on two commercial activated carbons: coconut shell Type PCB and hardwood Type BD. The isotherms of the water vapor were measured gravimetrically at 298 K. The isotherms of radon from dry nitrogen were obtained at 293, 298, and 308 K while the data for the mixture of radon and water vapor were measured at 298 K. The concentrations of radon in the gas and solid phases were measured simultaneously, once the adsorption equilibrium and the radioactive equilibrium between the radon and its daughter products were established. The shape of the isotherms was of Type III for the radon and Type V for the water vapor, according to Brunauer's classification. The adsorption mechanism was similar for both the radon and the water vapor, being physical adsorption on the macropore surface area in the low pressure region and micropore filling near saturation pressure. The uptake capacity of radon decreased both with increasing temperature and relative humidity. The heat of adsorption data indicated that the PCB- and the BD-activated carbons provided a heterogeneous surface for radon adsorption. The equilibrium data for radon were correlated with a modified Freundlich equation.
Email flow awareness and deferral strategies (2010)

The investigative methods traditionally employed by email researchers do not adequately capture the intricacies of email use over an entire day. This thesis improves upon these methods by using a novel combination of daylong in-situ shadowing and passive interface monitoring to provide new insights into how new messages are handled. The findings revealed previously undocumented actions for dealing with email on an ongoing basis, and showed that deferred message handling is a critical usage strategy that has been understudied. Interface logs were used to explore the defer action further and identified two types of email deferral: intra-session and inter-session deferral. This investigation highlights the frequent use of email as a real-time task and attention management tool, and demonstrates why this usage should be supported within email clients. This thesis finally makes the recommendation that future interface improvements should provide more flexible and lightweight mechanisms for integrating email into the user's workflow.
Cutting flexible printed circuit board with a 532NM Q-switched diode pumped solid state laser (2005)

The authors investigate the high-speed laser cutting of flexible printed circuit boards (PCBs) using a low M2 532nm laser to create features &lt;40 microns in size. The use of flexible PCBs in portable electronics devices such as laptops, PDAs and mobile phones is increasing as such material offers advantages in terms of weight and volume over conventional PCBs. Typically a laminar structure of copper - polyimide - copper, less than 50 microns thickness, this material is difficult to cut conventionally being prone to tearing and delamination. Cutting of &lt;50 micron thickness flexible PCB is investigated empirically using a low M2 532nm high average power Q-switched diode pumped solid state laser. Comparisons are made between different laser wavelengths including that of a 532nm frequency doubled laser and a fundamental wavelength 1064nm laser. Cutting speeds of &gt;120mm/s are reported with a high quality kerf.
Modeling Controlled Nutrient Release from Polymer Coated Fertilizers:  Diffusion Release from Single Granules (2003)

A comprehensive model describing the complex and "non-Fickian" (mathematically nonlinear) nature of the release from single granules of membrane coated, controlled release fertilizers (CRFs) is proposed consisting of three stages: i. a lag period during which water penetrates the coating of the granule dissolving part of the solid fertilizer in it ii. a period of linear release during which water penetration into and release out occur concomitantly while the total volume of the granules remains practically constant; and iii. a period of "decaying release", starting as the concentration inside the granule starts to decrease. A mathematical model was developed based on vapor and nutrient diffusion equations. The model predicts the release stages in terms of measurable geometrical and chemophysical parameters such as the following: the product of granule radius and coating thickness, water and solute permeability, saturation concentration of the fertilizer, and its density. The model successfully predicts the complex and "sigmoidal" pattern of release that is essential for matching plant temporal demand to ensure high agronomic and environmental effectiveness. It also lends itself to more complex statistical formulations which account for the large variability within large populations of coated CRFs and can serve for further improving CRF production and performance.

Reconstruction of Intima and Adventitia Models into a State Undeformed by a Catheter by Using CT, IVUS, and Biplane X-Ray Angiogram Images (2017)

The number of studies on blood flow analysis using fluid-structure interaction (FSI) analysis is increasing. Though a 3D blood vessel model that includes intima and adventitia is required for FSI analysis, there are difficulties in generating it using only one type of medical imaging. In this paper, we propose a 3D modeling method for accurate FSI analysis. An intravascular ultrasound (IVUS) image is used with biplane X-ray angiogram images to calculate the position and orientation of the blood vessel. However, these images show that the blood vessel is deformed by the catheter inserted into the blood vessel for IVUS imaging. To eliminate such deformation, a CT image was added and the two models were registered. First, a 3D model of the undeformed intima was generated using a CT image. In the second stage, a model of intima and adventitia deformed by the catheter was generated by combining the IVUS image and the X-ray angiogram images. A 3D model of intima and adventitia with the deformation caused by insertion of the catheter eliminated was generated by matching these 3D blood vessel models in different states. In addition, a 3D blood vessel model including bifurcation was generated using the proposed method.
Anisotropic finite-difference algorithm for modeling elastic wave propagation in fractured coalbeds (2012)

ABSTRACT The simulation of wave propagations in coalbeds is challenged by two major issues: (1) strong anisotropy resulting from high-density cracks/fractures in coalbeds and (2) numerical dispersion resulting from high-frequency content (the dominant frequency can be higher than 100 Hz). We present a staggered-grid high-order finite-difference (FD) method with arbitrary even-order (2L) accuracy to overcome the two difficulties stated above. First, we derive the formulae based on the standard Taylor series expansion but given in a neat and explicit form. We also provide an alternative way to calculate the FD coefficients. The detailed implementations are shown and the stability condition for anisotropic FD modeling is examined by the eigenvalue analysis method. Then, we apply the staggered-grid FD method to 2D and 3D coalbed models with dry and water-saturated fractures to study the characteristics of the 2D/3C elastic wave propagation in anisotropic media. Several factors, like density and direction of vertical cracks, are investigated. Several phenomena, like S-wave splitting and waveguides, are observed and are consistent with those observed in a real data set. Numerical results show that our formulae can correlate the amplitude and traveltime anisotropies with the coal seam fractures.
Quantum dots nanoparticle-based lateral flow assay for rapid detection of Mycobacterium species using anti-FprA antibodies (2012)

A lateral flow (LF) device combined with quantum dots (QDs) technology was developed for rapid detection of a specific mycobacterial flavoprotein reductase (<em>fprA</em>). In order to develop the LF assay based on a double-antibody sandwich format, two monoclonal antibodies recognizing different epitopes located in separated <em>fprA</em> domains were identified. The first monoclonal antibody was immobilized onto the detection zone of a porous nitrocellulose membrane, whereas another monoclonal antibody was conjugated to QDs nanoparticles as a detection system. Using these monoclonal antibodies we recorded a good fluorescence signal, the intensity of which was directly proportional to the concentration of <em>fprA</em> protein. The use of antibodies conjugated with fluorescent semiconductor QDs via biotin-streptavidin bridge, allowed the detection of <em>fprA</em> protein at concentrations as low as 12.5 pg/μL in less than 10 min. The reported technology could be useful in the diagnostic investigation of <em>Mycobacterium tuberculosis</em> and other human pathogens in clinical specimens.
Modeling personal and social network context for event annotation in images (2007)

This paper describes a framework to annotate images using personal and social network contexts. The problem is important as the correct context reduces the number of image annotation choices.. Social network context is useful as real-world activities of members of the social network are often correlated within a specific context. The correlation can serve as a powerful resource to effectively increase the ground truth available for annotation. There are three main contributions of this paper: (a) development of an event context framework and definition of quantitative measures for contextual correlations based on concept similarity in each facet of event context; (b) recommendation algorithms based on spreading activations that exploit personal context as well as social network context; (c) experiments on real-world, everyday images that verified both the existence of inter-user semantic disagreement and the improvement in annotation when incorporating both the user and social network context. We have conducted two user studies, and our quantitative and qualitative results indicate that context (both personal and social) facilitates effective image annotation.
Persistent formation of reagins in mice injected with low doses of ovalbuminl. (1971)

Immunization of mice with minute doses (0.1 μg) of ovalbumin in A1(OH)(3) gel induced persistent synthesis of high titres (1:160, 1:320) of reaginic and IgG1 antibodies. Immunization with high doses of ovalbumin (100 μg) induced high IgG1 titres but only weak and transient formation of reagins. Inbred mouse strains differ widely in their immune responsiveness to low doses of ovalbumin.
Removal of pollutants by plasma catalytic processes (2004)

Removal of molecular atmospheric pollutants by non-thermal plasmas is under study since the beginning of the eighties. It has been shown that pulsed electrical discharges, such as dielectric barrier or corona discharges, are powerful means to eliminate Volatile Organic Compounds (VOCs) from the ambient air, or to treat flue gases which contain nitrogen oxide. However it is now recognised that, for several pollutants, the use of the plasma alone does not allow a complete elimination of the undesirable molecule. For example NO is oxidised in the air plasma to form other oxides like NO2 and N2O5, and reactions of oxygen atoms or hydroxyl radicals produced by the discharge with VOCs can lead not only to H2O and CO2 but to a number of by-products following the partial oxidation of the molecule, which can be as undesirable than the compound to be initially removed from effluents. This is particularly the case when the electrical energy deposited in the gas flow must be kept as low as possible in order to design a low energy cost equipment. As a result addition of a catalyst together with the pulsed discharge is now investigated in various laboratories in order to achieve a complete oxidation of VOCs, i.e. the so-called de-COV process, or a complete reduction of NOX (NO and NO to produce N2 and O2, i.e. the so-called de-NOX process, at low energy consumption. This paper is a short review of works which have been done these last years in that domain, specifically on NOX and some selected VOC molecules.

A resonant signal driver for two-phase, almost-non-overlapping clocks (1996)

We describe a driver circuit for reducing the power dissipated when driving heavily loaded signals such as the clock lines of a VLSI chip. The design exhibits good power efficiency across a wide range of frequencies. We have tested the driver with a prototype shift-register chip which had a clock line load in the hundreds of picofarads. The worst-case overall dissipation was 35% of fCV/sup 2/ at 13 MHz and 5 V.
Formal verification of parallel programs (1976)

Two formal models for parallel computation are presented: an abstract conceptual model and a parallel-program model. The former model does not distinguish between control and data states. The latter model includes the capability for the representation of an infinite set of control states by allowing there to be arbitrarily many instruction pointers (or processes) executing the program. An induction principle is presented which treats the control and data state sets on the same ground. Through the use of “place variables,” it is observed that certain correctness conditions can be expressed without enumeration of the set of all possible control states. Examples are presented in which the induction principle is used to demonstrate proofs of mutual exclusion. It is shown that assertions-oriented proof methods are special cases of the induction principle. A special case of the assertions method, which is called parallel place assertions, is shown to be incomplete. A formalization of “deadlock” is then presented. The concept of a “norm” is introduced, which yields an extension, to the deadlock problem, of Floyd's technique for proving termination. Also discussed is an extension of the program model which allows each process to have its own local variables and permits shared global variables. Correctness of certain forms of implementation is also discussed. An Appendix is included which relates this work to previous work on the satisfiability of certain logical formulas.

Evaluating the design and delivery of WWW based educational environments and courseware (1998)

The mid 1990s has seen a significant growth in both the popularity and development of WWW based courseware and delivery. However, such efforts have been very variable in both effectiveness and comprehensiveness. This paper identifies a set of general requirements necessary in designing a pedagogically successful WWW based educational experience, which can be used in the assessment of WWW based educational courses. To illustrate how such requirements can be successfully addressed, the evaluation of a WWW based course which was trialed over a three-year period with approximately 300 students is presented.
