A transfer-matrix approach for estimating the characteristic impedance and wave numbers of limp and rigid porous materials (2000)

A method for evaluating the acoustical properties of homogeneous and isotropic porous materials that may be modeled as fluids having complex properties is described here. To implement the procedure, a conventional, two-microphone standing wave tube was modified to include: a new sample holder; a section downstream of the sample holder that accommodated a second pair of microphone holders and an approximately anechoic termination. Sound-pressure measurements at two upstream and two downstream locations were then used to estimate the two-by-two transfer matrix of porous material samples. The experimental transfer matrix method has been most widely used in the past to measure the acoustical properties of silencer system components. That procedure was made more efficient here by taking advantage of the reciprocal nature of sound transmission through homogeneous and isotropic porous layers. The transfer matrix of a homogeneous and isotropic, rigid or limp porous layer can easily be used to identify the material's characteristic impedance and wave number, from which other acoustical quantities of interest can be calculated. The procedure has been used to estimate the acoustical properties of a glass fiber material: good agreement was found between the estimated acoustical properties and those predicted by using the formulas of Delany and Bazley.
Optocoupler-Based Extension-Line Circuit for Electronic PABX's (1978)

A new approach for an extension-line circuit of a private automatic branch exchange (PABX), which does not depend on a line transformer and high-power feeder resistors, is described. A matched pair of electrooptical couplers is used in Place of the transformed they provide high-voltage-protected signal transmission with stable insertion loss and good dynamic range. Power dissipation of the feeding circuitry has been kept low by feeding the telephone with a constant line-independent current. A new status and signaling-detection concept is also described, which yields fast and reliable detection of status changes even in the presence of large common-mode signals during ring condition. Elimination of the transformer, reduction of power dissipation in the feeding circuitry, and maximum use of integrated and hybrid circuit technology lead to a high packing density.
Building Large Knowledge-Based Systems: Representation and Inference in the Cyc Project (1990)

The Cyc project, started by Doug Lenat at MCC in 1984, is the most ambitious knowledge representation project ever undertaken. It embodies Lenat's current ideas for a system intended to encode all of commonsense knowledge. By the year 1999, he hopes that no one would even think of buying a computer that doesn't have Cyc running on it. The book by Lenat and Guha is a report on the project as it was in 1989. A review of that book must distinguish four different things: the book itself, the Cyc project as it was when the book was written, the Cyc project today, and the developments that the designers are planning for the future. Of these four, the last two are probably the most interesting. This review has been difficult for me to write, because my thoughts about Cyc have changed a great deal since I first read the book in the spring of 1990. Doug Skuce showed me a copy of his review (which also appears in this issue), and it is similar to what I had originally intended to write. I agree with his complaints about the confusing organization of the book and the lack of precise definitions. Despite our reservations, we both used
Architecture design and management for data center networks (2012)

Driven by technology advances and economic forces, data centers are being built around the world to serve as the infrastructures for big data analysis services (e.g., GFS, Map-reduce, and Dryad), Internet-based applications (e.g., web search, e-commerce, and online social networking) and cloud computing services (e.g., Amazon EC2, Microsoft Windows Azure, and Google App Engine). Typically, a data center may contain thousands, tens of thousands or even millions of servers with significant inter-node bandwidth requirement between them. How to design efficient and sustainable data center network architectures, and how to manage/configure the networks are two fundamental challenges for data center networking (DCN) research, which form the basis of this Ph.D. dissertation work. 
Our research focuses on designing efficient DCN from both the architecture perspective and the management perspective. This dissertation is mainly composed of two key components called OSA and DAC. Specifically, OSA is a novel optical switching architecture for data center networks. At its core, by exploiting runtime reconfigurable optical devices, OSA flexibly adapts its topology and link capacities to various traffic patterns, thus achieving high network bisection bandwidth. The key idea we hope to deliver via OSA is that: a thin but flexible architecture, instead of static fat ones, can better support data center networking in a simple, cost-effective and sustainable way. On the other hand, DAC is a management system that can perform address autoconfiguration for both OSA network and other generic data center networks. DAC is motivated by the key observation that data center networks encode locality and topology information into their server and switch addresses for performance, reliability and routing purposes, making the traditional address autoconfiguration protocols, like DHCP, not applicable in the new data center environment. The core of DAC is to reduce the data center address autoconfiguration problem to the graph isomorphism (GI) problem and solve it efficiently by leveraging the data center network topology characteristics. 
Our designs have been evaluated and validated via extensive analysis, simulations and implementations. Particularly, we have prototyped OSA using the real optical devices and implemented DAC as an application over the Windows network stack.
Translingual Document Representations from Discriminative Projections (2010)

Representing documents by vectors that are independent of language enhances machine translation and multilingual text categorization. We use discriminative training to create a projection of documents from multiple languages into a single translingual vector space. We explore two variants to create these projections: Oriented Principal Component Analysis (OPCA) and Coupled Probabilistic Latent Semantic Analysis (CPLSA). Both of these variants start with a basic model of documents (PCA and PLSA). Each model is then made discriminative by encouraging comparable document pairs to have similar vector representations. We evaluate these algorithms on two tasks: parallel document retrieval for Wikipedia and Europarl documents, and cross-lingual text classification on Reuters. The two discriminative variants, OPCA and CPLSA, significantly outperform their corresponding baselines. The largest differences in performance are observed on the task of retrieval when the documents are only comparable and not parallel. The OPCA method is shown to perform best.
Minimum-volume transforms for remotely sensed data (1994)

Scatter diagrams for multispectral remote sensing data tend to be triangular, in the two-band case, pyramidal for three bands, and so on. They radiate away from the so-called darkpoint, which represents the scanner's response to an un-illuminated target. A minimum-volume transform may be described (provisionally) as a nonorthogonal linear transformation of the multivariate data to new axes passing through the dark point, with directions chosen such that they (for two bands), or the new coordinate planes (for three bands, etc.) embrace the data cloud as tightly as possible. The reason for the observed shapes of scatter diagrams is to be found in the theory of linear mixing at the subfootprint scale. Thus, suitably defined, minimum-volume transforms can often be used to unmix images into new spatial variables showing the proportions of the different cover types present, a type of enhancement that is not only intense, but physically meaningful. The present paper furnishes details for constructing computer programs to effect this operation. It will serve as a convenient technical source that may be referenced in subsequent, more profusely illustrated publications that address the intended application, the mapping of surface mineralogy.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Enumeration of Bacteriophages by Double Agar Overlay Plaque Assay (2009)

General analysis of [3 × 3] optical‐fiber directional couplers (1989)

Abstract The general analytic expressions of [3 × 3] optical fiber output are obtained by solving three linear differential equations using Laplace transform techniques. It may prove useful in explaining, designing, and manufacturing of [3 × 3] optical fiber couplers.
Anisotropic analysis of multi‐component T<sub>2</sub> and T<sub>1ρ</sub> relaxations in achilles tendon by NMR spectroscopy and microscopic MRI (2013)

Purpose: To study the anisotropic characteristics of both multi‐component T 2 and T 1ρ relaxation times in tendon. Materials and Methods: T 2 and T 1ρ were measured in tendon by NMR spectroscopy at different orientations and by microscopic MRI at the magic angle. Several experimental issues in the multi‐component relaxation measurements were investigated, including the effects of echo spacing, the resolution of MRI experiments, the influence of the specimen orientations, and the strengths of different spin‐lock frequencies in T 1ρ experiments. Results: Both the values and fractions of T 2 in tendon showed significant orientational dependence. The values and fractions of T 1ρ strongly depended on both the specimen orientation and the spin‐lock strength. The imaging resolution (35–280 μm) had little influence in the T 2 experiments. Both the echo spacings (0.6–3.0 ms) in the T 2 experiment and the spin‐lock strengths (0.5–5 kHz) in the T 1ρ experiment affected the quantification of the multi‐component relaxation. Up to three T 2 and T 1ρ components were resolved in tendon. Conclusion: Multi‐component relaxations could be attributed to different populations of water in the tissue. The transitions between a mono‐component and multi‐component result call for the caution in interpreting the relaxation results. J. Magn. Reson.

Adaptive QoS in Multimedia Systems (1997)

We propose the introduction of an abstract concept of QoS to all layers of the multimedia software architecture. Each layer in a software system deals with QoS at its appropriate level of abstraction using a generic API for communicating QoS parameters and values to layers above and below. We call the aggregation of these parameters and values a “service contract”. By mapping the contract at one layer to other contracts at the layer below we can build service hierarchies that allow the design of adaptive systems based on a single framework. Further the API allows for reporting of contract violations as well as dynamic renegotiations of the contract terms. To verify these ideas we built a proof-of-concept multimedia system (Ott, 1997) which showed that our architecture is not only feasible but offers a powerful framework for building adaptive multimedia systems.
AMOD: a morpholino oligonucleotide selection tool (2005)

AMOD is a web-based program that aids in the functional evaluation of nucleotide sequences through sequence characterization and antisense morpholino oligonucleotide (target site) selection. Submitted sequences are analyzed by translation initiation site prediction algorithms and sequence-to-sequence comparisons; results are used to characterize sequence features required for morpholino design. Within a defined subsequence, base composition and homodimerization values are computed for all putative morpholino oligonucleotides. Using these properties, morpholino candidates are selected and compared with genomic and transcriptome databases with the goal to identify target-specific enriched morpholinos. AMOD has been used at the University of Minnesota to design approximately 200 morpholinos for a functional genomics screen in zebrafish. The AMOD web server and a tutorial are freely available to both academic and commercial users at http://www.secretomes.umn.edu/AMOD/.

Personal home server: a software infrastructure for supporting spontaneous and personalized interaction in home computing environments (2005)

In this paper, we propose a personal home sewer that makes it possible to coordinate a variety of home appliances. Since each person has a different personal home server, it allows him/her to personalize how to use the appliances according to his preferences. Also, a personal home server can discover and configure appliances at any places, such as railroad stations, cars, and streets as well as houses in a seamless way. We show the design and implementation of a personal home server, and present its current status.
Characteristics of MOSFET with non-overlapped source-drain to gate region (2003)

A MOSFET structure with non-overlapped source-drain to gate region was proposed to overcome the challenges in sub-0.1 /spl mu/m CMOS device. Key device characteristics were investigated by extensive simulation study. Fringing gate electric field through the dielectric spacer induces inversion layer in the non-overlap region to act as extended S/D region. Electrons were induced reasonably under the spacer. Internal physics and speed characteristics were studied with the non-overlap distance. The proposed structure had good subthreshold slope and DIBL characteristics compared to those of overlapped structure.
Cataractogenous effect of hair dyes: a clinical and experimental study. (1979)

Observations based on a clinical and experimental study of the effect of hair dye (paraphenylenediamine) on the lens are reported. Two hundred individuals of either sex using hair dye were examined in detail and lenticular changes were found in 89% while only 23% in controls. The lenticular changes were related to duration, amount, and individual sensitivity to dye. Various types of lenticular opacities encountered are mentioned. In addition some individuals (7%) were found to develop early presbyopia. Experimental study which was conducted in rats and rabbits confirmed the cataractogenic effect of hair dye beyond doubt. It is concluded that hair dye is potentially toxic to the human lens.
Comparative Anesthetic Effects on Aqueous Humor Dynamics in the Cynomolgus Monkey (1984)

Cynomolgus monkeys were anesthetized with either intravenous (IV) ketamine hydrochloride, IV ketamine and intramuscular (IM) diazepam, IM methohexital sodium and IM pentobarbital sodium, or endotracheal halothane. Intraocular pressure, aqueous humor flow rate (F), anterior chamber volume, corneal endothelial transfer coefficient (Ka), and anterior chamber elimination coefficient (Ke) were determined noninvasively, using applanation tonometry, keratometry, pachymetry, and fluorophotometry. Arterial blood gases (ABG), acid-base balance, and mean arterial pressure (MAP) were monitored. The IOP was highest with ketamine and lowest with pentobarbital. The F and Ke were about 30% lower with halothane than with the other regimens, while Ka was highest with ketamine. The ABG and MAP were within normal physiologic limits with the three noninhalation regimens; pH was within normal limits with all four regimens. The MAP was lowest and PO2 highest with halothane, while pH was highest with pentobarbital.
Biological studies on 1,2-benzisothiazole derivatives V. Antimicrobial properties of N-alkanoic, N-arylalkanoic and N-aryloxyalkanoic derivatives of 1,2-benzisothiazolin-3-one: QSAR study and genotoxicity evaluation. (1996)

N-alkanoic, N-arylalkanoic and N-aryloxyalkanoic acids of 1,2-benzisothiazolin-3-one, esters and amides of N-arylalkanoic and N-aryloxyalkanoic acids and 1,1-dioxide derivatives of N-arylalkanoic acids and esters were investigated in vitro antimicrobial activity. N-arylalkanoic and N-aryloxyalkanoic acids (compounds 4-12) and their esters and amides (compounds 13-26) exhibited a good antimicrobial activity against Gram positive bacteria, with several compounds showing potencies 10-20 times higher than 1,2-benzisothiazolin-3-one. None of the chemicals tested inhibited the growth of E. coli. Yeasts and moulds possess a considerable susceptibility to compounds 12-23. The logP (octanol-water) of esters and amides of N-arylalkanoic and N-aryloxyalkanoic acids were measured by the shake-flask technique and the potencies against Gram positive bacteria of the compounds tested was related to their lipophilicity. QSAR analysis showed a bilinear relation, with a logD0 around 3 for the activity on B. subtilis. The phenoxyacetic and phenoxybutyric acid derivatives are positive outliers, showing a potency higher than that predicted from their lipohilicity. The most active compounds were further tested against different Gram positive bacteria and moulds, including Bacilli, Sarcina lutea, Staphylococcus epidermidis, Candida spp. and dermatophytes. The antibacterial and antifungal activity was specific for 1,2-benzisothiazolin-3-ones, the corresponding 1,1-dioxide derivatives being inactive. The genotoxic properties of the compounds studied were evaluated by the Bacillus subtilis rec-assay and Salmonella-microsome test. None of the compounds showed DNA-damaging or mutagenic activity.
Construction of low-density parity-check convolutional codes through progressive edge-growth (2005)

In this letter, we propose a novel approach of constructing low-density parity-check convolutional codes (LDPC-CCs), based on the progressive edge-growth (PEG) algorithm. LDPC-CC related modifications are made upon the original PEG algorithm to generate the time-varying parity-check matrix. The proposed method can generate LDPC-CCs with large girth, and is flexible in handling codes with different parameters. Simulation results show that such codes have good performance.
Elements for a cloud-based development environment (2012)

In almost any other field than software development, the World Wide Web, or simply the Web has revolutionized collaboration by providing a platform for cooperative applications and services. In contrast, so far revision control, also referred to as version management, has been the key technology for enabling collaborative software development. However, even today it is feasible to build a cooperative development environment that runs in a cloud, following the spirit of Google Docs, where developers can cooperate in real time. In this paper, we take a step beyond from the design of the technical artifact that allows collaborative coding, and consider the consequences of such an approach to software development in a more general sense, in particular from the perspective of version management. The goal is to integrate collaborative development with traditional facilities commonly associated with software engineering. This in turn will lead to a development approach where new opportunities complement tools that are known to work and provide a lot of added value in software development.
Electrical Restitution and Cardiac Fibrillation (2002)

Combined experimental and theoretical work has shown that restitution properties of the cardiac action potential duration and conduction velocity contribute to breakup of reentrant wavefronts during cardiac fibrillation independent of preexisting electrophysiologic heterogeneities in the tissue. Developing therapies that favorably alter these cardiac electrical restitution properties are a promising new approach to preventing fibrillation.

A fusion study in speech / music classification (2003)

In this paper, we present and merge two speech / music classification approaches of that we have developed. The first one is a differentiated modeling approach based on a spectral analysis, which is implemented with GMM. The other one is based on three original features: entropy modulation, stationary segment duration and number of segments. They are merged with the classical 4 Hertz modulation energy. Our classification system is a fusion of the two approaches. It is divided in two classifications (speech/non-speech and music/non-music) and provides 94 % of accuracy for speech detection and 90 % for music detection, with one second of input signal. Beside the spectral information and GMM, classically used in speech / music discrimination, simple parameters bring complementary and efficient information.
Bromonitromethane—a versatile electrophile (1986)

Pathways in reactions of bromonitromethane with a variety of nucleophiles have been investigated.With thiolates, the electrophilic centre is bromine and the initial products are disulphides. When the thiolate ion itself carries an electrophilic centre such as carbonyl or cyano β-to sulphur, the product is a nitrothiophene derived from subsequent reaction of the first-formed disulphide with nitronate ion displaced in the initial process. This provides a generalisation of earlier nitrothiophene synthesis by this route.In reactions with arenesulphinate ion, the electrophilic centre is also bromine and equilibration between the initial reactants and the initial products, sulphonyl bromide and nitronate ion, is established. The components of the equilibrium subsequently react either with each other or with the solvent. Reactions with sulphides are slow and distal substituents such as hydroxy- or cyano- so much reduce reactivity that no reaction is observed. Dimethyl sulphide attacks bromonitromethane at the carbon atom, and subsequent attack on the nitromethyl sulphonium salt initially formed gives methylthionitromethane and trimethylsulphonium bromide.Iodide ion attacks at bromine to give iodine, presumably via iodine bromide, but with tervalent phosphorus nucleophiles, attack is at oxygen giving the corresponding oxides and HCN in a double deoxygenation sequence. For hydroxide, methoxide, and hydride ions (from sodium borohydride), nucleophilic attack is at hydrogen and the nitronate ion produced is inert to further attack. There is no evidence of carbene formation by α-elimination.When the anion of bromonitromethane is allowed to react with tributylboron, the anionic migration–displacement which follows boron–carbon bond formation, yields 1-nitropentane.The anion of bromonitromethane is unreactive towards aldehydes and electrophilic alkenes.
