A Voltage-Based Controller for an Electric-Vehicle Charger (2015)

Electric vehicle (EV) integration into the distribution system has been a topic of great interest lately due to the potential challenges that it poses. Previous works have focused on either centralized charge control or distributed charge control to solve these issues. In this paper, an adaptive voltage-feedback controller for an onboard EV charger is proposed, which, unlike other proposed methods, requires no real-time communication between the EV and the utility. This controller compares the system voltage at the point of charging with a preset reference voltage. EV charging is reduced as the system voltage approaches this reference. The reduced charging rate takes into account the EV battery state of charge (SOC) and the owner's end-of-charge time (ECT) preference. To validate the proposed control structure, extensive simulations are carried out on a distribution system with and without other voltage control mechanisms. Simulation results show that this method can eliminate system voltage violations that would otherwise be caused by EV charging while ensuring fairness among the various EVs, even with different system configurations and EV penetration levels. The proposed controller shows good performance in the presence of other voltage control devices and distributed generation units. Moreover, it can integrate with vehicle-to-grid services as the lowest level of hierarchical control.
Effect of hyperbranched acrylates on UV‐curable soy‐based biorenewable coatings (2010)

Abstract Utilization of biorenewable components in UV‐curable coating formulations is both economically and environmentally beneficial, particularly when compared to their petrochemical‐based counterparts. To produce UV‐curable coatings of high biorenewable content with enhanced performance, acrylated epoxidized soybean oil (ASBO) was combined with biorenewable reactive diluent tetrahydrofufuryl acrylate, adhesion promoters, photoinitiator and hyperbranched acrylates (HBAs) as synthetic tougheners. The HBAs were found to impart high functionality and low viscosity, thus increasing crosslinking in the coating network and improving mechanical and thermal properties such as film hardness, adhesion, solvent resistance, impact resistance, tensile modulus and toughness, glass transition temperature and thermal stability. Real‐time Fourier transform infrared spectroscopy showed decreased acrylate conversion when compared with a reference formulation without HBAs, which was attributed to earlier coating network vitrification during UV irradiation. ASBO‐based coatings were also thermally annealed to allow further reaction of unreacted components in the vitrified network. As a result, coating properties were further improved. Overall, the addition of HBAs as synthetic tougheners to UV‐curable ASBO‐based biorenewable coating systems was shown to greatly improve the corresponding coating properties.

Proof of concept of peptide-linked blockmiR-induced MBNL functional rescue in myotonic dystrophy type 1 mouse model (2022)

Myotonic dystrophy type 1 is a debilitating neuromuscular disease causing muscle weakness, myotonia, and cardiac dysfunction. The phenotypes are caused by muscleblind-like (MBNL) protein sequestration by toxic RNA in the DM1 protein kinase (<i>DMPK</i>) gene. DM1 patients exhibit a pathogenic number of repetitions in <i>DMPK</i>, which leads to downstream symptoms. Another disease characteristic is altered microRNA (miRNA) expression. It was previously shown that miR-23b regulates the translation of <i>MBNL1</i> into protein. Antisense oligonucleotide (AON) treatment targeting this miRNA can improve disease symptoms. Here, we present a refinement of this strategy targeting a miR-23b binding site on the <i>MBNL1</i> 3' UTR in DM1 model cells and mice by using AONs called blockmiRs. BlockmiRs linked to novel cell-penetrating peptide chemistry showed an increase in MBNL1 protein in DM1 model cells and HSA<sup>LR</sup> mice. They also showed an increase in muscle strength and significant rescue of downstream splicing and histological phenotypes in mice without disturbing the endogenous levels of other miR-23b target transcripts.

A sensate liner for personnel monitoring applications (2002)

This program develops and demonstrates technologies useful for implementing a manageable cost effective systems approach to monitoring the medical condition of personnel by way of an instrumented uniform hereafter referred to as a Sensate Liner (SL). The SL consists of a form fitting garment which contains and interconnects sensing elements and devices to an electronics pack containing a processor and transmitter. The SL prototype requires fiber, textile, garment and sensor development. The SL textile consists of a mesh of electrically and optically conductive fibers integrated into the normal structure (woven or knitted) of fibers and yarns selected for comfort and durability. A suite of SL garment compatible embedded biological and physical sensors are then integrated into the SL. The initial SL sensor suite is selected to improve triage for combat casualties. Additional SL sensor concepts for medical monitoring are discussed.
An automated dye‐dilution based seepage meter for the time‐series measurement of submarine groundwater discharge (2003)

We designed an automated seepage meter that can detect and quantify both groundwater outflow and seawater infiltration. Based on a dye‐dilution technique, this instrument provides high‐resolution time‐series data for submarine groundwater discharge to the coastal zone. The dye‐dilution method involves two repeatable steps: (1) the timed injection of a water‐soluble dye into a “dye‐mixing chamber” mounted in series with a seepage chamber and (2) the subsequent timed measurements of the absorbance of the dyed solution. The rate at which the dyed solution is diluted by the inflow or outflow of water is directly proportional to the flow rate moving through the surface area of the seepage housing. In addition to describing the instrument's components and the operating principle, we provide examples of laboratory flow calibrations and field deployments. As indicated by two sets of time‐series studies, this instrument has performed reliably in field tests at Waquoit Bay (Cape Cod, Massachusetts) and Shelter Island (Long Island, New York). The instrument has yielded hydrologically consistent flow rates and has revealed major and subtle connections between tidal stage and the rate and direction of submarine groundwater discharge.
Real-Time Bayesian 3-D Pose Tracking (2006)

In this paper, we propose a novel approach for real-time 3-D tracking of object pose from a single camera. We formulate the 3-D pose tracking task in a Bayesian framework which fuses feature correspondence information from both previous frame and some selected key-frames into the posterior distribution of pose. We also developed an inter-frame motion inference algorithm which can get reliable inter-frame feature correspondences and relative pose. Finally, the maximum a posteriori estimation of pose is obtained via stochastic sampling to achieve stable and drift-free tracking. Experiments show significant improvement of our algorithm over existing algorithms especially in the cases of tracking agile motion, severe occlusion, drastic illumination change, and large object scale change
Minimal piggyBac vectors for chromatin integration (1138.12) (2014)

We describe novel transposon piggyBac vectors engineered to deliver transgenes as efficiently as currently available piggyBac systems, but with significantly less helper DNA co‐delivered into the host genome. To generate these plasmids, we identified a previously unreported aspect of transposon biology, that the full‐length terminal domains required for successful plasmid‐to‐chromatin transgene delivery can be repositioned from the transgene delivery cassette to the other (helper) parts of the plasmid. This design decreased the size of the required terminal domains within the delivered gene cassette of the piggyBac vector from about 1,500 to just 98 base pairs. Herein we tested the transposition efficiency of these minimal piggyBac transposons on different cell types: HEK293, HeLa, L929, and primary pulmonary artery smooth muscle cells. Transposition efficiency was defined as transgene (RFP) positivity at 28 days. The specificity of integration was determined by PCR and qPCR. Conclusion: Relocating most of the long terminal‐repeat sequences from the delivered gene cassette of minimal piggyBac vectors into the helper region of the same plasmid decreased the amount of non‐essential (helper) DNA incorporated into the host cell genome without a significant decrease in transposition efficiency. This may reduce the risk of target cell transformation. Grant Funding Source : Supported by the American Heart Association to V.S. (12GRNT12070291)
Zintl Chemistry for Designing High Efficiency Thermoelectric Materials (2009)

Zintl phases and related compounds are promising thermoelectric materials; for instance, high zT has been found in Yb14MnSb11, clathrates, and the filled skutterudites. The rich solid-state chemistry of Zintl phases enables numerous possibilities for chemical substitutions and structural modifications that allow the fundamental transport parameters (carrier concentration, mobility, effective mass, and lattice thermal conductivity) to be modified for improved thermoelectric performance. For example, free carrier concentration is determined by the valence imbalance using Zintl chemistry, thereby enabling the rational optimization of zT. The low thermal conductivity values obtained in Zintl thermoelectrics arise from a diverse range of sources, including point defect scattering and the low velocity of optical phonon modes. Despite their complex structures and chemistry, the transport properties of many modern thermoelectrics can be understood using traditional models for heavily doped semiconductors.
Raman fibre lasers emitting at a wavelength above 2 μm (2004)

Single-mode Raman fibre lasers emitting a few hundreds of millwatts at wavelengths of 2.0 and 2.2 μm are built for the first time. Laser emission was amplified in a fibre with a germanium dioxide core and a silica cladding pumped by an Er/Yb-doped fibre laser.
Pulsed Radio Frequency Plasma Polymerization of Allyl Alcohol:  Controlled Deposition of Surface Hydroxyl Groups (1996)

The utility of employing a variable duty cycle pulsed plasma polymerization technique to control film chemistry during plasma depositions is examined using allyl alcohol as monomer gas. Large scale progressive variations in film composition are observed with sequential changes in the plasma duty cycles employed, all other plasma variables being held constant. In particular, the −OH functionality of the monomer is increasingly retained in the plasma generated thin films as the radio frequency duty cycle is lowered. Fourier transform infrared and X-ray photoelectron spectroscopic analyses of the films obtained reveal that excellent film chemistry control is achieved during plasma polymerization of this monomer. The surface density controllability of functional groups, coupled with a gradient layering technique described herein to improve film adhesion to substrate surfaces, provides ideal opportunities for molecular tailoring of surfaces via subsequent derivatization reactions.
Recommending friends and locations based on individual location history (2011)

The increasing availability of location-acquisition technologies (GPS, GSM networks, etc.) enables people to log the location histories with spatio-temporal data. Such real-world location histories imply, to some extent, users' interests in places, and bring us opportunities to understand the correlation between users and locations. In this article, we move towards this direction and report on a personalized friend and location recommender for the geographical information systems (GIS) on the Web. First, in this recommender system, a particular individual's visits to a geospatial region in the real world are used as their implicit ratings on that region. Second, we measure the similarity between users in terms of their location histories and recommend to each user a group of potential friends in a GIS community. Third, we estimate an individual's interests in a set of unvisited regions by involving his/her location history and those of other users. Some unvisited locations that might match their tastes can be recommended to the individual. A framework, referred to as a hierarchical-graph-based similarity measurement (HGSM), is proposed to uniformly model each individual's location history, and effectively measure the similarity among users. In this framework, we take into account three factors: 1) the sequence property of people's outdoor movements, 2) the visited popularity of a geospatial region, and 3) the hierarchical property of geographic spaces. Further, we incorporated a content-based method into a user-based collaborative filtering algorithm, which uses HGSM as the user similarity measure, to estimate the rating of a user on an item. We evaluated this recommender system based on the GPS data collected by 75 subjects over a period of 1 year in the real world. As a result, HGSM outperforms related similarity measures, namely similarity-by-count, cosine similarity, and Pearson similarity measures. Moreover, beyond the item-based CF method and random recommendations, our system provides users with more attractive locations and better user experiences of recommendation.
Remote Detection of Fiber Fuse Propagating in Optical Fibers (2009)

A novel technique of remotely detecting fiber fuse from the electrical spectrum of backreflected light is proposed and demonstrated. When fuse occurred, a rise in signal level over 50dB was observed for frequencies ranging ~20-500 KHz.
Visible–Near‐Infrared and Fluorescent Copper Sensors Based on Julolidine Conjugates: Selective Detection and Fluorescence Imaging in Living Cells (2011)

We present novel Schiff base ligands julolidine-carbonohydrazone 1 and julolidine-thiocarbonohydrazone 2 for selective detection of Cu(2+) in aqueous medium. The planar julolidine-based ligands can sense Cu(2+) colorimetrically with characteristic absorbance in the near-infrared (NIR, 700-1000 nm) region. Employing molecular probes 1 and 2 for detection of Cu(2+) not only allowed detection by the naked eye, but also detection of varying micromolar concentrations of Cu(2+) due to the appearance of distinct coloration. Moreover, Cu(2+) selectively quenches the fluorescence of julolidine-thiocarbonohydrazone 2 among all other metal ions, which increases the sensitivity of the probe. Furthermore, quenched fluorescence of the ligand 2 in the presence of Cu(2+) was restored by adjusting the complexation ability of the ligand. Hence, by treatment with ethylenediaminetetraacetic acid (EDTA), thus enabling reversibility and dual-check signaling, julolidine-thiocarbonohydrazone (2) can be used as a fluorescent molecular probe for the sensitive detection of Cu(2+) in biological systems. The ligands 1 and 2 can be utilized to monitor Cu(2+) in aqueous solution over a wide pH range. We have investigated the structural, electronic, and optical properties of the ligands using ab initio density functional theory (DFT) combined with time-dependent density functional theory (TDDFT) calculations. The observed absorption band in the NIR region is attributed to the formation of a charge-transfer complex between Cu(2+) and the ligand. The fluorescence-quenching behavior can be accounted for primarily due to the excited-state ligand 2 to metal (Cu(2+)) charge-transfer (LMCT) processes. Thus, experimentally observed characteristic NIR and fluorescence optical responses of the ligands upon binding to Cu(2+) are well supported by the theoretical calculations. Subsequently, we have employed julolidine-thiocarbonohydrazone 2 for reversible fluorescence sensing of intracellular Cu(2+) in cultured HEK293T cells.
Delineation of Human Antibody Responses to Culture Filtrate Antigens of<i>Mycobacterium tuberculosis</i> (1998)

This study was undertaken to define the antigens in culture filtrates of actively replicating Mycobacterium tuberculosis that are recognized by antibodies from tuberculosis (TB) patients. Two-dimensional Western blots were probed with sera from healthy controls and TB patients that were preabsorbed with Escherichia coli lysates to deplete cross-reactive antibodies. Antibodies from TB patients recognized 26 of the >100 culture filtrate proteins, and the repertoire changed with disease progression. Only 12 of 26 antigens, including 3 proteins implicated in colonization and invasion by mycobacteria (MPT51, MPT32, and 85C), and 9 (as yet undefined proteins) were reactive with sera from TB patients with early noncavitary or cavitary disease. Eight additional antigens, including 4 undefined proteins, were recognized only by sera from a subset of patients with advanced cavitary disease. Studies suggest that 3 of the antigens recognized by sera from patients with early TB (85C, MPT32, and a 88-kDa protein) have strong serodiagnostic potential.
Novel bilateral filter approach: Image noise reduction with sharpening (2006)

The classical bilateral filter smoothes images and preserves edges using a nonlinear combination of surrounding pixels. Our modified bilateral filter advances this approach by sharpening edges as well. This method uses geometrical and photometric distance to select pixels for combined low and high pass filtering. It also uses a simple window filter to reduce computational complexity.
Antibody immunotherapy targeting the self-tumor antigen nucleolin (VAC5P.1129) (2015)

Abstract Nucleolin is a multifunctional protein found in the nucleus of all cells, and it’s a self-tumor antigen. It is overexpressed on the plasma membrane and cytoplasm of the two most common forms of leukemia acute myeloid leukemia (AML) and chronic lymphocytic leukemia (CLL). The cell surface expression of nucleolin on CLL and AML cells, compared with its nuclear profile in normal cells, makes nucleolin an attractive self-antigenic target for antibody immunotherapy. Accordingly, we have utilized our patented platform technology (US Patent 8,715,743) to generate a panel of fully human monoclonal antibodies (HuMAbs) that target nucleolin (NCL) and potently induce AML cell death, while having no effect on normal blood cells (PCT/US2010/057046). Preliminary data indicated that AML cells were killed independently of complement or antibody dependent cellular cytotoxic mechanisms, possibly by interfering with nucleolin’s cellular function. This might have significant therapeutic implications, since the HuMAbs may retain activity in immunocompromised leukemia patients. We hypothesize that the anti-NCL HuMAbs have both immune mediated and immune independent antitumor activity, eliciting nucleolin specific killing through both complement and cell mediated cytotoxic mechanisms, and through interfering with the integral cellular function of nucleolin. Thus, autoreactive antibodies targeting this self-tumor antigen might be important in the treatment of leukemia.
<title>Laser treatment of port wine stains: three-dimensional simulation using biopsy-defined geometry in an optical-thermal model</title> (1998)

The efficacy of laser treatment of port wine stains (PWS) has been shown to be highly dependent on the patient-specific structure of vascular lesions. To improve the accuracy of PWS numerical models, an optical-thermal model simulating an arbitrarily complex, three dimensional tissue geometry has been developed. In this model, the distribution of absorbed radiant energy -- determined using a modified Monte Carlo technique -- is used as the source term in a finite difference thermal model that predicts transient temperature rise. The Arrhenius rate process integral is then used to calculate thermal damage. Simulations based on a tomographic reconstruction of a PWS biopsy were performed for laser pulse durations of 0.5, 5.0 and 50.0 ms and a wavelength of 585 nm. Irradiances that produced maximum tissue temperatures of 120 degrees Celsius were used. The simulations indicated that energy deposition in blood is primarily a function of depth in skin. Thermal diffusion effects increased with longer pulse duration, leading to collateral damage observed at 5.0 and 50.0 ms. A pulse duration of 0.5 ms resulted in confinement of thermal damage to blood regions. Clusters of small vessels tended to behave similarly to larger vessels, reaching higher temperatures and creating more damage in the surrounding dermis than isolated vessels. The incorporation of realistic geometry into an optical-thermal model represents a significant advance in computer modeling of laser surgery.

Doping of BiScO3-PbTiO3 Ceramics for Enhanced Properties (2008)

High-temperature piezoelectrics are a key technology for aeronautics and aerospace applications such as fuel modulation to increase the engine efficiency and decrease emissions. The principal challenge for the insertion of piezoelectric materials is the limitation on upper use temperature which is due to low Curie-Temperature (T(sub c) and increasing electrical conductivity. BiScO3 -PbTiO3 (BS-PT) system is a promising candidate for improving the operating temperature for piezoelectric actuators due to its high TC (>400 C). Effects of Zr and Mn doping of the BS-PT ceramics have been studied and all electrical and electromechanical properties for Sc-deficient and Ti-deficient BS- PT ceramics are reported as a function of electrical field and temperature. Donor doping with Zr and Mn (in Sc deficient compositions) increased the DC-resistivity and decreased tan at all temperatures. Resulting ceramics exhibited saturated hysteresis loops with low losses and showed no dependence on the applied field (above twice the coercive field) and measurement frequency.
