Information fusion for image analysis: geospatial foundations for higher-level fusion (2003)

In support of the AFOSR program in Information Fusion, the CNS Technology Laboratory at Boston University is developing and applying neural models of image and signal processing, pattern learning and recognition, associative learning dynamics, and 3D visualization, to the domain of Information Fusion for Image Analysis in a geospatial context. Our research is focused by a challenge problem involving the emergence of a crisis in an urban environment, brought on by a terrorist attack or other man-made or natural disaster. We aim to develop methods aiding preparation and monitoring of the battlespace, deriving context from multiple sources of imagery (high-resolution visible and low-resolution hyperspectral) and signals (GMTI from moving vehicles, and ELINT from emitters). This context will serve as a foundation, in conjunction with existing knowledge nets, for exploring neural methods in higher level information fusion supporting situation assessment and creation of a common operating picture (COP).
ProvSQL (2018)

This demonstration showcases ProvSQL, an open-source module for the PostgreSQL database management system that adds support for computation of provenance and probabilities of query results. A large range of provenance formalisms are supported, including all those captured by provenance semirings, provenance semirings with monus, as well as where-provenance. Probabilistic query evaluation is made possible through the use of knowledge compilation tools, in addition to standard approaches such as enumeration of possible worlds and Monte-Carlo sampling. ProvSQL supports a large subset of non-aggregate SQL queries.

Snubber circuit and MOSFET paralleling considerations for high power boost-based power-factor correctors (2002)

Use of appropriate snubber circuit and paralleling of power switches are very important issues for high power boost power convertor-based power factor correctors. This paper shows that practical approach to the snubbing problem is a simple turn-on snubber with di/dt control of the diode reverse-recovery transition. Implementation of such a snubber in boost power converters with paralleled MOSFET switches is then discussed.
Low‐Firing, Temperature‐Stable Dielectric Compositions Based on Bismuth Nickel Zinc Niobates (1990)

Low‐sintering dielectric materials with small temperature co‐efficients were developed. The newly developed materials are based on the Bi 2 (ZnNb 2 )O 9 and Bi 3 (Ni 2 Nb)O 9 system with a bismuth‐layered crystal structure. Preliminary results show that these materials have relatively large dielectric constants of 80 to 100, small temperature coefficients of ≤20 × 10 −6 /°C, and relatively large Q values of 2000 to 3000. Furthermore, these materials can be sintered at temperatures ranging from 850° to 950°C, and these low sintering temperatures might permit the use of a less expensive silver electrode. These materials compare favorably with the conventional NPO (small temperature coefficient) dielectric materials based on MgTiO 3 .

Combined effect of amphotericin B and rifampin on Candida species (1980)

Synergism with the combination of rifampin and amphotericin B in vitro has been demonstrated with a limited number of Candida strains. To extend these studies (particularly at clinically achievable levels of rifampin), we evaluated the in vitro combined activity of serial twofold dilutions of amphotericin B (0.1 to 6.0 microgram/ml) against 11 concentrations of rifampin (0.2 to 200 microgram/ml) for 40 strains of Candida: 20 Candida albicans, 7 Candida parapsilosis, 8 Candida tropicalis, 2 Candida stellatoidea, 2 Candida guilliermondii, and 1 Candida krusei by using a modified checkerboard microtitration technique. An additive or synergistic effect was seen for 45% of strains with 6.25 microgram of rifampin per ml added to amphotericin B. Whereas the minimal inhibitory concentration to amphotericin B alone was 0.4 microgram/ml or less for 50% of the strains, the percentage increased to 90 with the addition of 6.25 microgram of rifampin per ml. A similar effect was seen with killing: 25% of the strains were killed by 0.4 microgram or less of amphotericin B alone per ml, and 75% of the strains were killed with the addition of 6.25 microgram of rifampin per ml. In vivo studies are needed for confirmation of the usefulness of combined amphotericin B and rifampin therapy.
Evaluation in Calves of an Inactivated Bovine Rhinotracheitis and Parainfluenza-3 Vaccine Combined with Pasteurella Bacterin (1972)

SUMMARY An inactivated infectious bovine rhinotracheitis ( ibr ) virus vaccine was prepared and tested in calves alone and in combination with an inactivated bovine parainfluenza-3 ( pi -3) virus vaccine and a pasteurella bacterin. Vaccinated calves were protected against virulent ibr virus challenge. The increases in ibr serum-neutralization ( sn ) and pi -3 hemagglutination-inhibition ( hi ) antibody titers in vaccinated calves were statistically significant. Adverse reactions were not observed in calves following vaccination.
Ability of oral bacteria to degrade fibronectin (1986)

The fibronectin-degrading ability of 116, mainly oral, strains was assayed by using plasma-derived fibronectin adsorbed to a polystyrene surface. Ability to degrade fibronectin was revealed in strains of Bacteroides gingivalis, Bacteroides intermedius, Bacteroides loeschii, Staphylococcus aureus, Staphylococcus epidermidis, Peptococcus prevotii, Clostridium sporogenes, and Propionibacterium acnes. The fibronectinolytic activity of subgingival bacteriological samples was found to be related to the presence of B. gingivalis and B. intermedius. In addition, strains of the nonoral Bacteroides species B. asaccharolyticus and B. fragilis showed fibronectin-degrading ability. No such ability was detected in the oral strains tested of Streptococcus, Veillonella, Actinomyces, Lactobacillus, Actinobacillus, Capnocytophaga, Fusobacterium, or Haemophilus species.
Mechanism of thermal denaturation of maltodextrin phosphorylase from Escherichia coli (2000)

Maltodextrin phosphorylase from Escherichia coli (MalP) is a dimeric protein in which each approximately 90-kDa subunit contains active-site pyridoxal 5'-phosphate. To unravel factors contributing to the stability of MalP, thermal denaturations of wild-type MalP and a thermostable active-site mutant (Asn-133-->Ala) were compared by monitoring enzyme activity, cofactor dissociation, secondary structure content and aggregation. Small structural transitions of MalP are shown by Fourier-transform infrared spectroscopy to take place at approximately 45 degrees C. They are manifested by slight increases in unordered structure and (1)H/(2)H exchange, and reflect reversible inactivation of MalP. Aggregation of the MalP dimer is triggered by these conformational changes and starts at approximately 45 degrees C without prior release into solution of pyridoxal 5'-phosphate. It is driven by electrostatic rather than hydrophobic interactions between MalP dimers, and leads to irreversible inactivation of the enzyme. Aggregation is inhibited efficiently and specifically by oxyanions such as phosphate, and AMP which therefore, stabilize MalP against the irreversible denaturation step at 45 degrees C. Melting of the secondary structure in soluble and aggregated MalP takes place at much higher temperatures of approx. 58 and 67 degrees C, respectively. Replacement of Asn-133 by Ala does not change the mechanism of thermal denaturation, but leads to a shift of the entire pathway to a approximately 15 degrees C higher value on the temperature scale. Apart from greater stability, the Asn-133-->Ala mutant shows a 2-fold smaller turnover number and a 4.6-fold smaller energy of activation than wild-type MalP, probably indicating that the site-specific replacement of Asn-133 brings about a greater rigidity of the active-site environment of the enzyme. A structure-based model is proposed which explains the stabilizing interaction between MalP and oxyanions, or AMP.
Resource Allocation and Power Control for Mobile Relay in TDD-OFDMA Downlink (2008)

This paper investigates the system performances of the IEEE 802.16j system with mobile relays such as cell throughput and service coverage. It also focuses on resource management problems such as overlapped subchannel allocation (OVSA) and orthogonal subchannel allocation (ORSA) and relay power control such as simplified on-off mobile relay control (SOMRC). The performance of the proposed schemes is evaluated with both proportional fair (PF) and mobility assisted opportunistic scheduling (MAOS) by SH. Ali and V.C.M. Leung (2005) schedulers. Simulation results show that the cell throughputs of the proposed schemes are greater than one without relay, and the cell throughput of OVSA scheme is improved with increasing the number of mobile relay stations (MRSs). OVSA with SOMRC also provides larger cell throughput than OVSA without MRS power control. The service coverage of ORSA scheme is greater than one of OVSA scheme, and OVSA with SOMRC offers expanded service coverage than OVSA without MRS power control.

Multi-frame alignment of planes (2003)

Traditional plane alignment techniques are typically performed between pairs of frames. In this paper we present a method for extending existing two-frame planar-motion estimation techniques into a simultaneous multi-frame estimation, by exploiting multi-frame geometric constraints of planar surfaces. The paper has three main contributions: (i) we show that when the camera calibration does not change, the collection of all parametric image motions of a planar surface in the scene across multiple frames is embedded in a low dimensional linear subspace; (ii) we show that the relative image motion of multiple planar surfaces across multiple frames is embedded in a yet lower dimensional linear subspace, even with varying camera calibration; and (iii) we show how these multi-frame constraints can be incorporated into simultaneous multi-frame estimation of planar motion, without explicitly recovering any 3D information, or camera calibration. The resulting multi-frame estimation process is more constrained than the individual two-frame estimations, leading to more accurate alignment, even when applied to small image regions.
Mouse/human sequence divergence in a region with a paternal-specific methylation imprint at the human H19 locus (1996)

We have identified a region with characteristics of a paternal-specific methylation imprint at the human H19 locus. This region, extending from -2.0 kb upstream to the start of transcription, is heavily methylated in sperm and on the paternal allele in somatic cells. This methylation was preserved during pre-implantation. Structural analysis revealed the presence of CpG islands and a large direct repeat with a 400 bp sequence reiterated several times, but no significant sequence homology to the corresponding region of the mouse H19 gene. These findings could suggest a role for secondary DNA structure in genomic imprinting across the species, and they also present a puzzling aspect of the evolution of the H19 regulatory region in human and mouse.
Probing Context-Dependent Errors in Quantum Processors (2019)

Gates in error-prone quantum information processors are often modeled using sets of one-and two-qubit process matrices, the standard model of quantum errors. However, the results of quantum circuits on real processors often depend on additional external "context" variables. Such contexts may include the state of a spectator qubit, the time of data collection, or the temperature of control electronics. In this article, we demonstrate a suite of simple, widely applicable, and statistically rigorous methods for detecting context dependence in quantum-circuit experiments. They can be used on any data that comprise two or more "pools" of measurement results obtained by repeating the same set of quantum circuits in different contexts. These tools may be integrated seamlessly into standard quantum device characterization techniques, like randomized benchmarking or tomography. We experimentally demonstrate these methods by detecting and quantifying crosstalk and drift on the publicly accessible 16-qubit ibmqx3.

Improved recess‐ohmics in AlGaN/GaN high‐electron‐mobility transistors with AlN spacer layer on silicon substrate (2010)

Abstract A systematic investigation of recess‐ohmic contact by inductively coupled plasma etching using four layers Ti/Al/Ni/Au metal on un‐doped AlGaN/GaN HEMT structure with a thin AlN spacer layer grown on silicon substrate were performed. Although the insertion of the thin AlN spacer layer effectively increases the two‐dimensional electron gas concentration and electron mobility due to the enhanced 2DEG confinement, it causes much difficulty in forming ohmic contacts. This problem has been resolved by recess‐ohmic approach prior to ohmic metalization. Improved HEMT characteristics were demonstrated by this technique. About 17.5% of increase in I Dmax and 12.5% of increase in g mmax were observed by recess ohmics. This improved device performance is due to the reduction of R c , R d and R s values by recess‐ohmics. From this investigation, we found that recess‐ohmics are essential to achieve high performance device characteristics in un‐doped AlGaN/GaN HEMTs with AlN spacer layer grown on Si substrate (© 2010 WILEY‐VCH Verlag GmbH & Co.

BIGtensor (2016)

Many real-world data are naturally represented as tensors, or multi-dimensional arrays. Tensor decomposition is an important tool to analyze tensors for various applications such as latent concept discovery, trend analysis, clustering, and anomaly detection. However, existing tools for tensor analysis do not scale well for billion-scale tensors or offer limited functionalities. In this paper, we propose BIGtensor, a large-scale tensor mining library that tackles both of the above problems. Carefully designed for scalability, BIGtensor decomposes at least 100× larger tensors than the current state of the art. Furthermore, BIGtensor provides a variety of distributed tensor operations and tensor generation methods. We demonstrate how BIGtensor can help users discover hidden concepts and analyze trends from large-scale tensors that are hard to be processed by existing tensor tools.

Microcell-mediated transfer of a single human chromosome complements xeroderma pigmentosum group A fibroblasts. (1987)

Chromosomes from an immortalized aneuploid human fibroblast cell line were randomly tagged with the selectable marker neo by transfection with the plasmid pSV2neo. Somatic cell fusions between transfected human cells and mouse A9 cells generated pools of G418-resistant human-mouse hybrid clones containing various numbers of human chromosomes. Microcell-mediated chromosome transfer from the hybrid pools to xeroderma pigmentosum complementation group A (XP-A) cells in culture and selection for G418-resistant colonies resulted in the identification of XP cells with enhanced resistance to ultraviolet radiation. Screening of subclones from selected pools of human-mouse hybrids facilitated the identification of hybrids containing a single neo-tagged human chromosome. Transfer of this chromosome to XP-A cells (but not to XP-F or XP-C cells) results in enhanced resistance to ultraviolet light and enhanced excision repair capacity. The identification of a single human chromosome that complements the phenotype of XP-A cells in culture provides the potential for genetic mapping of the complementing gene and for its isolation by molecular cloning.

Microporous Cyanate Resins: Synthesis, Porous Structure, and Correlations with Gas and Vapor Adsorptions (2012)

Three silicon and nitrogen-centered cyanate monomers tetrakis(4-cyanatophenyl)silane, tetrakis(4-cyanatobiphenyl)silane, and tris(4-cyanatobiphenyl)amine were designedand synthesized, which were then polymerized via thermal cyclotrimerization reaction to create highly porous cyanate resin networks with systematically varied nodes and linking struts. The chemical structures of monomers and polymers were confirmed by 1H NMR, FTIR, solid-state 13C CP/MAS NMR spectra, and elemental analysis. The products are amorphous with 5% weight-loss temperatures over 428 °C. The results based on N2 and CO2 adsorption isotherms show that the pores in these polymers mainly locate in the microporous region, and the BET surface areas are up to 960 m2 g–1, which is the highest value for the porous cyanate resin reported to date. The nitrogen- and oxygen-rich characteristics of cyanate resins lead to the networks strong affinity for CO2 and thereby high CO2 adsorption capacity of 11.1 wt % at 273 K and 1.0 bar. The adsorption behaviors of H2, CO2, benzene, n-hexane, and water vapors were investigated by correlating with the chemical composition and porosity parameters of the networks as well as the physicochemical nature of adsorbates.
Rerouting for handoff in a wireless ATM network (2002)

Handoff is the procedure by which a user's radio link is transferred between radio ports in the network without an interruption of the user connection. In this paper, we discuss how a wireless asynchronous transfer mode (ATM) network may reroute a user connection during a handoff. We propose a novel procedure called "nearest common node rerouting (NCNR)". NCNR is designed to perform the rerouting of user connections due to a handoff event in a fast and efficient manner. We conclude by comparing NCNR to other rerouting schemes discussed in the literature.
