End-host multicasting in support of distributed real-time simulation systems (2004)

There has recently been a tremendous level of interest in the use of end-host multicast to provide group communication within a wide area network. End-host multicast shifts the burden of group-communication support from network routers to the host. End-host multicasting is required when IP multicasting is not available. The difficulty in using this technique is that it requires additional resource consumption when compared to native IP multicasting. This work presents several novel end-host multicast algorithms designed for peer-to-peer real-time simulation systems. Our techniques utilize application level admission control in order to more fairly balance the communication load in the physical network. We propose and evaluate an adaptive routing policy to find overflow paths between end-hosts and simulation agents placed within the system. We also present several heuristics for routing tree construction, including a simulated annealing approach. We have evaluated our methods through simulation, and the results show that our methods achieve performance similar to optimal IP multicasting.
Depolarised broadband source (1983)

A depolarised broadband source is demonstrated by depolarising the output of a superluminescent diode with a short length of Hitachi single polarisation fibre. A degree of polarisation of less than 10−3 is achieved.
A Response Unit in the First Exon of the β-Amyloid Precursor Protein Gene Containing Thyroid Hormone Receptor and Sp1 Binding Sites Mediates Negative Regulation by 3,5,3′-Triiodothyronine (2004)

Thyroid hormones repress expression of APP (beta-amyloid precursor protein) in cultured cells of neuronal origin. The effect involves binding to the nuclear thyroid hormone receptor (TR) and is mediated by DNA sequences located within the first exon of the gene. These sequences contain a thyroid hormone response element that is necessary, but not sufficient, to mediate the inhibitory effect of the thyroid hormone T(3). In this report, we show that repression by T(3) is mediated by a response unit composed by the thyroid hormone response element and 5'-flanking sequences that bind Sp1 and mediate stimulation by this transcription factor. In that unit, binding sites for TR and Sp1 overlap and a complex mechanism appears to account for the TR-mediated regulation of APP. Unliganded TR does not bind to DNA and allows Sp1 to bind to DNA and stimulate APP basal expression. Binding of ligand T(3), which increases affinity of TR by DNA, precludes binding of Sp1 to DNA and decreases the Sp1-dependent expression of APP.
Crohn's disease, ulcerative colitis or indeterminate colitis--how important is it to differentiate? (2001)

In most patients coming to the general practitioner or specialist with a history of bloody diarrhoea, bacteria or drugs are the most likely causative agents and it will be possible to make a diagnosis fairly easily. Because of differences in treatment, ulcerative colitis (UC) and Crohn's disease (CD) must however seriously be considered especially in younger patients, with severe symptoms and whenever the history is prolonged. A variety of colitides may indeed be clinically confused with UC and CD. Pathological mimics that should not be missed include infectious diseases such as Campylobacter colitis, yersiniosis, amoebiasis and others; drug-induced diseases (due to nonsteroidal antiinflammatory drugs...); diverticular disease-associated colitis; intestinal endometriosis; intestinal vasculitis and Behçet's disease and iatrogenic conditions such as graft-versus-host-disease and radiation colitis. In most situations a precise diagnosis of these conditions should be possible when all data are available. The term "indeterminate colitis" is used, when a diagnosis of chronic idiopathic inflammatory bowel disease (IBD) is suggested, but the differential diagnosis between UC and CD can not be solved. This occurs in approximately 5% of all patients with IBD. Diagnostic problems can occur in acute fulminant colitis, acute prolonged colitis, chronic relapsing disease and pouchitis. Indeterminate colitis is essentially a temporary diagnosis. Surgical and medical treatment of these patients can be difficult. When surgical treatment is indicated, the type of surgery must be seriously considered. The clinical course of patients with indeterminate colitis is usually more severe when compared with classical UC and these patients require often more severe medical treatment. Diagnostic problems can also arise in longstanding IBD, either UC and CD. Relapse of symptoms can be due to intercurrent infection (CMV is one of the candidates). Medical treatment can influence the microscopic features and induce a discontinuous inflammation in UC, reminiscent of CD. In cases of doubt, the original biopsies should be reviewed to ascertain the diagnosis, and orient treatment.
LUC: A New Public Key System (1993)

We describe public key cryptosystems and analyse the RSA cryptosystem, pointing out a weakness (already known) of the RSA system. We define Lucas functions and derive some of their properties. Then we introduce a public key system based on Lucas functions instead of exponentiation. The computational requirements of the new system are only a little greater than those for the RSA system, and we prove that the new system is cryptographically stronger than the RSA system. Finally, we present a Lucas function equivalent of the DiffieHellman key negotiation method. Keyword Codes: E.3; K.4.2; K.6.5 Keywords: Data Encryption; Social Issues; Security and Protection 1. Public Key Encryption Public-key encryption was first discussed by Diffie and Hellman [1] as a general principle. The new concept which they introduced was the use of trapdoor functions for cryptography. A trapdoor function is a computable function whose inverse can be computed in a reasonable amount of time only if a (small) amou...
Non-separable extensions of quadrature mirror filters to multiple dimensions (1990)

Generalized non-separable extensions of quadrature mirror filter (QMF) banks to two and three dimensions, in which the orientation specificity of the high-pass filters is greatly improved, are described. In particular, extensions to two dimensions with hexagonal symmetry, and 3-D spatiotemporal extensions with rhombic-dodecahedral symmetry, are discussed. Although these filters are conceived and designed on nonstandard sampling lattices, they can be applied to rectangularly sampled images. As in one dimension, these transformations can be hierarchically cascaded to form a multiscale pyramid representation. A set of example filters is designed and applied to the problems of image compression, progressive transmission, orientation analysis, and motion analysis.

Normal and perturbed Chinese hamster ovary cells: correlation of DNA, RNA, and protein content by flow cytometry. (1985)

Quantitative, correlated determinations of DNA, RNA, and protein, as well as RNA to DNA and RNA to protein ratios, were performed on three-color stained cells using a multiwavelength-excitation flow cytometer. DNA-bound Hoechst 33342 (blue), protein-fluorescein isothiocyanate (green), and RNA-bound pyronin Y (red) fluorescence measurements were correlated as each stained cell intersected three spatially separated laser beams. The analytical scheme provided sensitive and accurate fluorescence determinations by minimizing the effects of overlap in the spectral characteristics of the three dyes. Computer analysis was used to generate two-parameter contour density profiles as well as to obtain numerical data for subpopulations delineated on the basis of cellular DNA content. Such determinations allowed for analysis of RNA to DNA and RNA to protein ratios for cells within particular regions of the cell cycle. The technique was used to study the interrelationship of DNA, RNA, and protein contents in exponentially growing Chinese hamster ovary cells as well as in cell populations progressing the cell cycle after release from arrest in G1 phase. The sensitivity of the method for early detection of conditions of unbalanced growth is demonstrated in the comparison of the differential effects of the cycle-perturbing agent, adriamycin, on cells treated either during exponential growth or while reversibly arrested in G1 phase.
CDC: Convolutional-De-Convolutional Networks for Precise Temporal Action Localization in Untrimmed Videos (2017)

Temporal action localization is an important yet challenging problem. Given a long, untrimmed video consisting of multiple action instances and complex background contents, we need not only to recognize their action categories, but also to localize the start time and end time of each instance. Many state-of-the-art systems use segment-level classifiers to select and rank proposal segments of pre-determined boundaries. However, a desirable model should move beyond segment-level and make dense predictions at a fine granularity in time to determine precise temporal boundaries. To this end, we design a novel Convolutional-De-Convolutional (CDC) network that places CDC filters on top of 3D ConvNets, which have been shown to be effective for abstracting action semantics but reduce the temporal length of the input data. The proposed CDC filter performs the required temporal upsampling and spatial downsampling operations simultaneously to predict actions at the frame-level granularity. It is unique in jointly modeling action semantics in space-time and fine-grained temporal dynamics. We train the CDC network in an end-to-end manner efficiently. Our model not only achieves superior performance in detecting actions in every frame, but also significantly boosts the precision of localizing temporal boundaries. Finally, the CDC network demonstrates a very high efficiency with the ability to process 500 frames per second on a single GPU server.

Application-specific array processors (2003)

An application-specific array processor (ASAP) means a high-speed, application-driven, massively parallel, modular, and programmable computing system. The ever-increasing super-high-speed requirement (in giga/tera FLOPS) in modern engineering applications suggests that mainframe scientific computers will not be adequate for many real-time signal/image processing and scientific computing applications. Therefore, the new trend of real-time computing systems points to special-purpose parallel processors, whose architecture is dictated by the very rich underlying algorithmic structures and therefore optimized for high-speed processing of large arrays of data. It is also recognized that a fast-turnaround design environment will be in a great demand for such parallel processing systems. This has become more realistic and more compelling with the increasingly mature VLSI and CAD technology. Therefore, a major advance in the state of the art in the next decade or so is expected. How to effectively design an application-specific parallel processing system which leads to a fast-turnaround design methodology is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Thickness of the Pre- and Post–Contact Lens Tear Film Measured In Vivo by Interferometry (2003)

Prelens tear thickness was in reasonable agreement with prior measurements. Postlens tear thickness was much less than the 11 to 12 microm found by the pachymetric method. It is argued that the current method avoids some of the systematic errors of the pachymetric method and also has much higher precision.
Merged CMOS/bipolar technologies and microwave MESFETs utilizing zone-melting-recrystallized SOI films (1984)

Two merged CMOS/bipolar technologies utilizing SOI structures have been demonstrated. In each case a single sequence of processing steps was used to fabricate fully isolated CMOS devices and vertical bipolar transistors on the same Si wafer. The CMOS devices were fabricated in a zone-melting-recrystallized SOI film, while the bipolar devices were fabricated either in the SOI film or in epitaxial Si layers grown selectively on the Si substrate. Good electrical characteristics were obtained for the CMOS devices and for both SOI and epitaxial bipolar devices. In addition, microwave MESFETs have been fabricated in zone-melting-recrystallized Si films on bulk fused-silica substrates. These devices exhibited maximum frequency of oscillation of 8-14 GHz. At 1.2 GHz, an optimum noise figure of 2.5 dB and associated gain of 10.4 dB were measured.
Multi-objective optimization of sensor quality with efficient marine vehicle task execution (2006)

This paper describes the in-field operation of two interacting autonomous marine vehicles to demonstrate the suitability of interval programming (IvP), a novel mathematical model for multiple-objective optimization. Broadly speaking, IvP coordinates competing control needs such as primary task execution that depends on a sufficient position estimate, and vehicle maneuvers that will improve that position estimate. In this work, vehicles cooperate to improve their position estimates using a sequence of vehicle-to-vehicle range estimates from acoustic modems. Coordinating primary task execution and sensor quality maintenance is a ubiquitous problem, especially in underwater marine vehicles. This work represents the first use of multiobjective optimization in a behavior-based architecture to address this problem
Beyond User-Specificity for EMG Decoding Using Multiresolution Muscle Synergy Analysis (2013)

Electromyographic (EMG) processing is a vital step towards converting noisy muscle activation signals into robust features that can be decoded and applied to applications such as prosthetics, exoskeletons, and human-machine interfaces. Current state of the art processing methods involve collecting a dense set of features which are sensitive to many of the intra- and inter-subject variability ubiquitous in EMG signals. As a result, state of the art decoding methods have been unable to obtain subject independence. This paper presents a novel multiresolution muscle synergy (MRMS) feature extraction technique which represents a set of EMG signals in a sparse domain robust to the inherent variability of EMG signals. The robust features, which can be extracted in real time, are used to train a neural network and demonstrate a highly accurate and user-independent classifier. Leave-one-out validation testing achieves mean accuracy of 81.9± 3.9% and area under the receiver operating characteristic curve (AUC), a measure of overall classifier performance over all possible thresholds, of 92.4± 8.9%. The results show the ability of sparse MRMS features to achieve subject independence in decoders, providing opportunities for large-scale studies and more robust EMG-driven applications.
Immunofluorescent Assay for the Marine Ammonium-Oxidizing Bacterium <i>Nitrosococcus oceanus</i> (1980)

Nitrification is one of the important microbiological transformations of nitrogen in the ocean. Traditional enrichment-culture methods for enumerating the autotrophic bacteria which oxidize ammonium to nitrite are very time consuming (months) and are believed to seriously underestimate natural abundances. A fluorescent-antibody assay for a marine ammonium-oxidizing bacterium was developed to provide a rapid and direct means of identifying these microorganisms. Antibodies to Nitrosococcus oceanus were prepared and tested against pure cultures of marine, freshwater, and soil ammonium oxidizers and against bacteria from natural seawater samples. Cell counts of culture samples determined by the fluorescent-antibody assay agreed with hemacytometer and acridine orange counts. Our results demonstrated that the immunofluorescent assay is a powerful tool for the detection of Nitrosococcus in the marine environment.
Towards a Multi-camera Mouse-replacement Interface (2010)

We present our efforts towards a multi-camera mouse-replacement system for computer users with severe motion impairments. We have worked with individuals with cerebral palsy or multiple sclerosis who use a publicly-available interface that tracks the user's head movements with a single video camera and translates them into mouse pointer coordinates on the screen. To address the problem that the interface can lose track of the user's facial feature due to occlusion or spastic movements, we started to develop a multi-camera interface. Our multi-camera capture system can record synchronized images from multiple cameras and automatically analyze the camera arrangement. We recorded 15 subjects while they were conducting a hands-free interaction experiment. We reconstructed via stereoscopy the three-dimensional movement trajectories of various facial features. Our analysis shows that single-camera interfaces based on two-dimensional feature tracking neglect to take into account the substantial feature movement in the third dimension.
Predicting N-terminal myristoylation sites in plant proteins (2004)

Superior performance of the new model is due to the selection of a plant-specific training set, covering 266 unique sequence examples from 40 different species, the use of a probability-based hidden Markov model to obtain predictive scores, and a threshold cutoff value chosen to provide maximum positive-negative discrimination. The new model has been used to predict 589 plant proteins likely to contain N-terminal myristoylation signals, and to analyze the functional families in which these proteins occur.
Mapping the domains on the phosphoprotein of bovine respiratory syncytial virus required for N–P and P–L interactions using a minigenome system (2001)

The interaction of bovine respiratory syncytial virus (BRSV) phosphoprotein (P) with nucleocapsid (N) and large polymerase (L) proteins was investigated using an intracellular BRSV-CAT minigenome replication system. Coimmunoprecipitation assays using P-specific antiserum revealed that the P protein can form complexes with N and L proteins. Deletion mutant analysis of the P protein was performed to identify the regions of P protein that interact with N and L proteins. The results indicate that two independent N-binding sites exist on the P protein: an internal region of 161-180 amino acids and a C-terminal region of 221-241 amino acids. The L-binding site was mapped to a region of P protein encompassing amino acids 121-160. The data suggest that N and L protein binding domains on the P protein do not overlap.
Selective synthesis of structurally isomeric poly‐β‐ester and poly‐δ‐ester from β‐(2‐acetoxy‐ethyl)‐β‐propiolactone with Al and Zn catalysts (1982)

Abstract It was found that structurally isomeric polymers were formed by the ring‐opening polymerization of β‐(2‐acetoxy ethyl)‐β‐propiolactone with (EtAlO) n and Et(ZnO) 2 ZnEt catalysts; that is, the Al catalyst catalyzed normal polymerization which led to poly‐β‐ester and the Zn catalyst formed isomerized poly‐β‐ester as the main product. The polymer structure was determined by nuclear magnetic resonance (NMR), T 1 ‐value, thermal decomposition product, and ( T g ). The NMR studies for the monomer–catalyst systems indicated that the Al catalyst interacted predominately with the lactone group, whereas the Zn catalyst interacted with the side‐chain ester group. These site‐selective interactions could be related to the difference in the stereoregulation by the two catalysts during the poly(β‐ester)‐forming polymerization process.
Control of Spectral Properties of Strontium-Alkaline Earth-Silicate-Europium Phosphors for LED Applications (2005)

-based phosphors doped by were studied for use in white light emitting diodes (LEDs). Variations of excitation and emission spectra by changes in the alkaline earth ions in host lattice were studied. It was found that the system was excellent for white LED applications with excitation in the 380-465 nm region. Specially, the yellow light intensity from was comparable to yttrium aluminum garnet:Ce phosphors for excitation at 465 nm (blue-emitting LED). The peak excitation wavelength could be controlled by the ratio in the host lattice. Also, it was found that phosphors efficiently emit blue light at 405 nm excitation.
Proteolytic Processing Regulates Placental Growth Factor Activities (2013)

Placental growth factor (PlGF) is a critical mediator of blood vessel formation, yet mechanisms of its action and regulation are incompletely understood. Here we demonstrate that proteolytic processing regulates the biological activity of PlGF. Specifically, we show that plasmin processing of PlGF-2 yields a protease-resistant core fragment comprising the vascular endothelial growth factor receptor-1 binding site but lacking the carboxyl-terminal domain encoding the heparin-binding domain and an 8-amino acid peptide encoded by exon 7. We have identified plasmin cleavage sites, generated a truncated PlGF118 isoform mimicking plasmin-processed PlGF, and explored its biological function in comparison with that of PlGF-1 and -2. The angiogenic responses induced by the diverse PlGF forms were distinct. Whereas PlGF-2 increased endothelial cell chemotaxis, vascular sprouting, and granulation tissue formation upon skin injury, these activities were abrogated following plasmin digestion. Investigation of PlGF/Neuropilin-1 binding and function suggests a critical role for heparin-binding domain/Neuropilin-1 interaction and its regulation by plasmin processing. Collectively, here we provide new mechanistic insights into the regulation of PlGF-2/Neuropilin-1-mediated tissue vascularization and growth.
