A Matlab implementation of a fast incremental principal component pursuit algorithm for Video Background Modeling (2014)

In this proposal we present a Matlab-only implementation of a simple, novel, and fully incremental Principal Component Pursuit (PCP) algorithm for Video Background Modeling. Our implementation can process full HD color 1920 × 1088 videos at a rate of 0.61 seconds per frame running on a standard laptop (Intel i7-2670QM quad-core, 6GB RAM, 2.2 GHz). Unlike other incremental or online PCP-like algorithms, such as ReProCS, GRASTA or pROST, the initialization stage of our implementation is extremely fast, has modest memory requirements (6.5 seconds and less than 0.5 Gb for a full HD video), and is also able to quickly adapt to changes in the background. Moreover our implementation can also process live-feed videos, which in our proposed demonstration will be acquired via a wireless camera, resulting in an interactive demonstration where the the moving objects to be segmented are the audience.
Posttranslationally modified peptides efficiently mimicking neoantigens: A challenge for theragnostics of autoimmune diseases (2010)

We report the design, synthesis, and immunological evaluation of a series of glycopeptide analogues of the previously described antigenic probe CSF114(Glc), with the aim of understanding the importance of N-glycosylation on Asn residue in multiple sclerosis antibody recognition. The glucopeptide, characterized by a β-turn conformation which is fundamental for a correct presentation of the epitope, has been modified by introducing various natural glycoamino acids in position 7. The new glycopeptides were evaluated by measuring the IgG and IgM antibody titer in multiple sclerosis patients' and normal blood donors' sera. Moreover, we achieved the efficient synthetic strategy of new Asn derivative bearing N-acetylneuraminic acid (Neu5Ac), linked by an N-glycosidic bond, on the side chain of the Asn residue orthogonally protected for Fmoc/tBu SPPS.
Prompt-based Content Scoring for Automated Spoken Language Assessment (2013)

This paper investigates the use of prompt-based content features for the automated as-sessment of spontaneous speech in a spoken language proficiency assessment. The results show that single highest performing prompt-based content feature measures the number of unique lexical types that overlap with the listening materials and are not contained in either the reading materials or a sample re-sponse, with a correlation of r = 0.450 with holistic proficiency scores provided by hu-mans. Furthermore, linear regression scor-ing models that combine the proposed prompt-based content features with additional spoken language proficiency features are shown to achieve competitive performance with scoring models using content features based on pre-scored responses. 1
Reduction of Writing Field Distribution in a Magnetic Random Access Memory With Toggle Switching (2007)

We have investigated the distribution of the flop field, which represents writing field in a toggle magnetic random access memory (MRAM). We analyzed the factors of the distribution by dividing them into the 45deg and f 35deg directions in (H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> , H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">y</sub> ) coordinates. We found that the distribution in the 135deg direction is mainly caused by stress-induced anisotropy and can be effectively suppressed by adopting materials that maintain low magnetostriction even after the fabrication process. On the other hand, we found that the distribution in the 45deg direction depends on the texture and atomic structure of the ferromagnetic layers, and that low distribution can be attained when the ferromagnetic layers are constructed from small crystalline grains or amorphous materials. We demonstrated a toggle MRAM with a distribution of the flop field only half that of the previously reported magnetic tunnel junction stack structure.
Highly Elastic Micropatterned Hydrogel for Engineering Functional Cardiac Tissue (2013)

Heart failure is a major international health issue. Myocardial mass loss and lack of contractility are precursors to heart failure. Surgical demand for effective myocardial repair is tempered by a paucity of appropriate biological materials. These materials should conveniently replicate natural human tissue components, convey persistent elasticity, promote cell attachment, growth and conformability to direct cell orientation and functional performance. Here, microfabrication techniques are applied to recombinant human tropoelastin, the resilience-imparting protein found in all elastic human tissues, to generate photocrosslinked biological materials containing well-defined micropatterns. These highly elastic substrates are then used to engineer biomimetic cardiac tissue constructs. The micropatterned hydrogels, produced through photocrosslinking of methacrylated tropoelastin (MeTro), promote the attachment, spreading, alignment, function, and intercellular communication of cardiomyocytes by providing an elastic mechanical support that mimics their dynamic mechanical properties in vivo. The fabricated MeTro hydrogels also support the synchronous beating of cardiomyocytes in response to electrical field stimulation. These novel engineered micropatterned elastic gels are designed to be amenable to 3D modular assembly and establish a versatile, adaptable foundation for the modeling and regeneration of functional cardiac tissue with potential for application to other elastic tissues.
Towards the observation of exceptional points (EPs) in passive plasmonic nanostructures (Conference Presentation) (2018)

We present progress on the experimental observation of exceptional points (EPs) in passive plasmonic nanostructures. The system has EPs which are degeneracies in open wave systems where at least two energy levels and their corresponding eigenstates coalesce. They manifest themselves by the simultaneous degeneracy of both resonant frequencies and its linewidths. We consider a plasmonic system based on a multilayer plasmonic structure with structural offset [1, 2]. The realization of an EP via hybridized modes requires the control of at least two physical parameters. The two parameters used for the above system to reach an EP are the shift between bars and the periodicity.
Dynamic vertical handover control algorithm for WLAN and UMTS (2006)

In this paper, a novel vertical handover control algorithm, consisting of a throughput-based mapping function, QoS-based dynamic handover thresholds, and performance-based trigger timers, is proposed to resolve uncommon pilot problems, QoS requirements, and ping-pong effects, respectively. A numerical analysis is provided to evaluate the proposed algorithm in terms of the handover frequency and achievable throughput. The performance is further quantified by a simulation based on mixed of UMTS and WLAN systems
Beaconless pointing and tracking for bidirectional optical links using MEMS mirror nutation (2021)

Free-space laser links traditionally utilize an independent spatial tracking channel with a beacon laser and tracking sensors to meet stringent pointing requirements. In this work, we propose a miniaturized monostatic beaconless fiber transceiver that infers fine tracking information using existing receiver optoelectronics and a small injected pointing dither (nutation). A single MEMS steering mirror is used to both fine-point the beams and inject nutation. While this results in some additional link loss due to disturbed fiber coupling and transmit beam pointing, our analysis shows the loss becomes negligible for sufficient SNR. Links without point-ahead correction need an SNR of about 35 dB to minimize the dither loss below 0.1 dB and also maintain the RMS spatial tracking noise below a tenth of the beam divergence. Since the pointing and tracking bandwidth is typically many orders of magnitude slower than the receiver communication bandwidth, such SNR is usually achievable on the receiver with appropriate filtering. If point-ahead correction is needed, we show that depending on the available link margin, a transceiver based on single-mode fiber can reach up to about 1 beamwidth of correction, while a few-mode fiber design can reach up to about 1.75 beamwidths due to improved coupling sensitivity at higher point-ahead offsets. Finally, we propose the use of double-clad fiber with a secondary detector to help further minimize the incurred coupling loss.
Recursively Partitioned Static IP Router Tables (2010)

We propose a method-recursive partitioning-to partition a static IP router table so that when each partition is represented using a base structure, such as a multibit trie or a hybrid shape shifting trie, there is a reduction in both the total memory required for the router table as well as in the total number of memory accesses needed to search the table. The efficacy of recursive partitioning is compared to that of the popular front-end table method to partition IP router tables. Our proposed recursive partitioning method outperformed the front-end method of all our test sets.
Inverse spectroscopic Optical Coherence Tomography (ISOCT): non-invasively quantifying the complete optical scattering properties from week scattering tissue (2012)

The complete set of the scattering properties of tissue including the phase function can be locally quantified by ISOCT. The method inversely quantifies the tissue refractive index (R.I.) correlation function to deduce the optical properties.
Synthesis and Characterization of Sterically Stabilized Second-Order Nonlinear Optical Chromophores (1999)

Bulky substituents added to second-order nonlinear optical (NLO) chromophores inhibit intermolecular electrostatic interactions that attenuate electric poling induced macroscopic electrooptic activity. Such chromophore modification also improves chemical and photochemical stability and the processability of chromophores into hardened, optical-quality polymer materials by improving solubility. We present a new route to the synthesis of electrooptic (second-order NLO) chromophores based on sterically protected π-electron bridge structures, yielding molecules exhibiting both large optical nonlinearity and good thermal stability.
Coherent Doppler Lidar for Precision Navigation of Spacecrafts (2011)

A fiber-based coherent Doppler lidar, utilizing an FMCW technique, has been developed and its capabilities demonstrated through two successful helicopter flight test campaigns. This Doppler lidar is expected to play a critical role in future planetary exploration missions because of its ability in providing the necessary data for soft landing on the planetary bodies and for landing missions requiring precision navigation to the designated location on the ground. Compared with radars, the Doppler lidar can provide significantly higher precision velocity and altitude data at a much higher rate without concerns for measurement ambiguity or target clutter. Future work calls for testing the Doppler lidar onboard a rocket-powered free-flyer platform operating in a closed-loop with the vehicle s guidance, navigation, and control (GN&C) unit.

Effects of MnO-Al <sub>2</sub> O <sub>3</sub> on the Grain Growth and High-Temperature Deformation Strain of UO <sub>2</sub> Fuel Pellets (2010)

The fabrication and high-temperature deformation strain of MnO-Al 2 O 3 -doped UO 2 pellets were studied.The effects of additive composition and amount on the microstructure evolution of a UO 2 pellet were investigated.The compressive creep behaviors of MnO-Al 2 O 3 -doped UO 2 pellets were examined.The results indicated that a MnO-Al 2 O 3 binary additive can effectively promote the grain growth of UO 2 pellets.In addition, the high-temperature deformation strain of the UO 2 pellet can be improved significantly with 1,000 ppm 95MnO-5Al 2 O 3 (mol%).The developed MnO-Al 2 O 3 -additive-containing UO 2 pellets can be a potential candidate for a high-burn-up fuel and a pellet-cladding interaction (PCI) remedy.

A switch matrix operating with multi-rate digital data streams has been developed and demonstrated. The circuit is to serve as a commutating switch in a multi-band multi-channel receiver. The switch works in space-division mode commutating single-bit multi-rate data streams. A 2 times 2 version of the switch matrix was designed, fabricated at HYPRES 1-kA/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , and tested at data rates in excess of 20 GHz. The design and test results will be presented. The final version of the device will be a 3 times 8 switch matrix operating at 40 Gbit/s data rate.
Insecticidal properties of genetically engineered baculoviruses expressing an insect juvenile hormone esterase gene (1992)

Exploring the possibility of enhancing the properties of baculoviruses as biological control agents of insect pests, we tested the effect of expressing an insect gene (jhe) encoding juvenile hormone esterase. Juvenile hormone esterase inactivates juvenile hormone, which regulates the outcome of an insect molt. A cDNA encoding the juvenile hormone esterase of Heliothis virescens was inserted into the genome of Autographa californica nuclear polyhedrosis virus such that the gene was expressed under the control of a strong, modified viral promoter. This virus, however, naturally encodes an ecdysteroid UDP-glucosyltransferase which inactivates ecdysone, the hormone which initiates molting. Since ecdysteroid UDP-glucosyltransferase could mask the effects of jhe expression by blocking molting entirely, jhe-expressing viruses in which the ecdysteroid UDP-glucosyltransferase gene was deleted or disrupted were constructed. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of proteins from infected cells revealed several intracellular proteins and two major secreted proteins which reacted with antibodies to authentic juvenile hormone esterase. Western blot analysis coupled with tunicamycin treatment indicated that differential glycosylation was responsible for the multiple products. Hemolymph of recombinant virus-infected fourth-instar Trichoplusia ni larvae contained levels of juvenile hormone esterase activity 40-fold higher than maximal levels found in uninfected larvae. However, little or no difference in developmental characteristics, weight gain, or time of mortality was observed between insects infected with the jhe-expressing viruses and control viruses.
Water-equivalent plastic scintillation detectors for high-energy beam dosimetry: I. Physical characteristics and theoretical considerations (1992)

A minimally perturbing plastic scintillation detector has been developed for the dosimetry of high-energy beams in radiotherapy. The detector system consists of two identical parallel sets of radiation-resistant optical fibre bundles, each connected to independent photomultiplier tubes (PMTs). One fibre bundle is connected to a miniature water equivalent plastic scintillator and so scintillation as well as Cerenkov light generated in the fibres is detected at its PMT. The other 'background' bundle is not connected to the scintillator and so only Cerenkov light is detected by its PMT. The background signal is subtracted to yield only the signal from the scintillator. The water-equivalence of plastic scintillation detectors is studied for photon and electron beams in the radiotherapy range. Application of Burlin cavity theory shows that the energy dependence of such detectors is expected to be better than the commonly used systems (ionization chambers, LiF thermoluminescent dosimeters, film and Si diodes). It is also shown that they are not affected by temperature variations and exhibit much less radiation damage than either photon or electron diode detectors.
Rational design of heat stable lyophilized rotavirus vaccine formulations (2018)

To develop a safe and efficacious heat-stable rotavirus vaccine, new lyophilized formulations were developed using rotavirus serotypes constituting RotaTeq®. A series of formulation compositions, differing in buffering agents, bulking agents, cryoprotectants, amino acids and divalent cations, were screened for their ability to provide stability to rotavirus serotypes during lyophilization and when stored under elevated temperatures for extended periods. Lead formulations and lyophilization cycles were further optimized. Stability profiles of thus optimized formulations showed their ability to retain the potency of rotavirus for > 36 months at 5°C, 20 months at 37°C, and 7 months at 45°C. The heat-stable lyophilized rotavirus formulations developed met the all critical quality attributes for appearance, heat-stability during storage, moisture content as well as pH, viability and stability after reconstitution and has great potential to be used as vaccine candidates for improving access in low-income countries.
Vaccines against invasive<i>Salmonella</i>disease (2014)

Though primarily enteric pathogens, Salmonellae are responsible for a considerable yet under-appreciated global burden of invasive disease. In South and South-East Asia, this manifests as enteric fever caused by serovars Typhi and Paratyphi A. In sub-Saharan Africa, a similar disease burden results from invasive nontyphoidal Salmonellae, principally serovars Typhimurium and Enteritidis. The existing Ty21a live-attenuated and Vi capsular polysaccharide vaccines target S. Typhi and are not effective in young children where the burden of invasive Salmonella disease is highest. After years of lack of investment in new Salmonella vaccines, recent times have seen increased interest in the area led by emerging-market manufacturers, global health vaccine institutes and academic partners. New glycoconjugate vaccines against S. Typhi are becoming available with similar vaccines against other invasive serovars in development. With other new vaccines under investigation, including live-attenuated, protein-based and GMMA vaccines, now is an exciting time for the Salmonella vaccine field.
Monkey-derived monoclonal antibodies against Plasmodium falciparum. (1985)

A system has been developed that allows efficient production of monkey monoclonal antibodies from owl monkeys. Splenocytes or peripheral blood lymphocytes from monkeys immune to the human malarial parasite, Plasmodium falciparum, were fused with P3X63 Ag8.653 mouse myelomas. The resulting hybridomas were screened by an indirect fluorescent antibody test for the production of monkey monoclonal antibodies (mAb) reactive with P. falciparum. Most of the mAb reacted with the P. falciparum merozoites and immunoprecipitated a parasite-derived glycoprotein having a relative molecular weight of 185,000. These mAb gave a minimum of five different immunoprecipitation patterns, thus demonstrating that a large number of polypeptides obtained when parasitized erythrocytes are solubilized share epitopes with this large glycoprotein. In addition, mAb were obtained that reacted with antigens associated with the infected erythrocyte membrane. One of these mAb bound a Mr 95,000 antigen.
Method and apparatus for synthesizing HMX and N/sub 2/O/sub 5/. [Patent application; cyclotetramethylenetetraamine] (1982)

A method and apparatus for electrochemically synthesizing N/sub 2/O/sub 5/ includes oxidizing a solution of N/sub 2/O/sub 4//HNO/sub 3/ at an anode, while maintaining a controlled potential between the N/sub 2/O/sub 4//HNO/sub 3/ solution and the anode. A potential of about 1.35 to 2.0V vs. SCE is preferred, while a potential of about 1.80V vs. SCE is most preferred. Thereafter, the N/sub 2/O/sub 5/ is reacted with either 1.5-diacetyl-3,7-dinitro-1,3,5,7-tetraazacyclooctane (DADN) or 1,3,5,7-tetraacetyl-1,3,5,7-tetraazacyclooctane (TAT) to form cyclotetramethylenetetraamine (HMX).
Multiresolution learning paradigm and signal prediction (1997)

Current neural network learning processes, regardless of the learning algorithm and preprocessing used, are sometimes inadequate for difficult problems. We present a new learning concept and paradigm for neural networks, called multiresolution learning, based on multiresolution analysis in wavelet theory. The multiresolution learning paradigm can significantly improve the generalization performance of neural networks.
A New Angle-Independent Doppler Ultrasonic Device for Assessment of Blood Flow Volume in the Extracranial Internal Carotid Artery (2002)

The FlowGuard showed that volume flow studies in the internal carotid artery could be easily performed, with results compatible with those of previous clinical reports. Duplex comparative results and breath-induced changes in internal carotid artery flow volume justify further evaluation of the system.
A semi-fragile watermarking system for MPEG video authentication (2002)

Video authentication is expected to prove the integrity of the content. Common authentication techniques do not allow any form of manipulation, thus making it impractical for some applications such as transcoding. In this paper, we shall propose an authentication scheme which can survive the bit-rate-conversion transcoding methods by using public, imperceptible semi-fragile watermark. Nowadays, videos are only available in compressed format in many applications. We will focus on the authentication of MPEG video. We will first provide a new classification of video tampering methods. Based on that, we shall propose our own authentication system. The proposed approach has a good locality corresponding to MPEG structure.
The Biology of TRAIL and the Role of TRAIL-Based Therapeutics in Infectious Diseases (2009)

TNF-related apoptosis inducing ligand (TRAIL) is a key mediator of the innate immune response to infection. While TRAIL-mediated apoptosis plays an essential role in the clearance of virus-infected cells, its physiologic role also includes immunosurveilance for cancer cells. Therapeutics that induce TRAIL-mediated apoptosis in cancer cells remain a focus of ongoing investigation in clinical trials, and much has been learned from these studies regarding the efficacy and toxicity of these interventions. These data, combined with data from numerous preclinical studies that detail the important and multifaceted role of TRAIL during infection with human immunodeficiency virus and other viruses, suggest that therapeutic exploitation of TRAIL signaling offers a novel and efficacious strategy for the management of infectious diseases.
