MMSS: Multi-Modal Story-Oriented Video Summarization (2005)

We propose multi-modal story-oriented video summarization (MMSS) which, unlike previous works that use fine-tuned, domain-specific heuristics, provides a domain-independent, graph-based framework. MMSS uncovers correlation between information of different modalities which gives meaningful story-oriented news video summaries. MMSS can also be applied for video retrieval, giving performance that matches the best traditional retrieval techniques (OKAPI and LSI), with no fine-tuned heuristics such as tf/idf.
Numerical simulation of actively controlled space structures (1990)

The numerical simulation of large, actively controlled space structures is a problem that has received considerable attention. A new computational method is presented in this paper, which simulates the vibration suppression of a large space structure by a linear compensator. The structure is assumed to be modeled by a large linear finite element model. Nested circularly linked lists and the trapezoidal rule are key aspects of this algorithm. There is an emphasis on generality, while establishing an equivalence between numerical stability and system stability.

Ballistic impact behavior of carbon nanotube and nanosilica dispersed resin and composites (2012)

Experimental studies are presented on the ballistic impact behavior of nanoparticle dispersed materials viz. symmetric balanced cross-ply laminates made using unidirectional E-glass fabric with epoxy resin and neat epoxy resin. The nanoparticles used are nanosilica and multi-walled carbon nanotube for polymer matrix composites and nanosilica for epoxy resin. For comparison, studies are carried out on symmetric balanced cross-ply E-glass/epoxy and neat epoxy resin without nanoparticles. Effect of nanoparticle dispersion on ballistic limit velocity, V50 and energy absorbed has been studied. It is observed that V50 can be enhanced up to 6.3% for polymer matrix composites and up to 7.3% for neat resin on addition of nanoparticles. Also, energy absorbed can be increased up to 13.0% for polymer matrix composites and up to 15.2% for neat resin on addition of nanoparticles. Damage and energy absorbing mechanisms for different types of materials studied is also presented. Further, it is observed that the damage size on the target around the point of impact decreases on addition of nanoparticles. Quantitative data are given for high velocity impact behavior of the five types of specimens studied.
Structure and properties of the outer membranes of Brucella abortus and Brucella melitensis. (1998)

The brucellae are Gram-negative bacteria characteristically able to multiply facultatively within phagocytic cells and which cause a zoonosis of world-wide importance. This article reviews the structure and topology of the main components (lipopolysaccharide, native hapten polysaccharide, free lipids and proteins) of the outer membranes of Brucella abortus and B. melitensis, as well as some distinctive properties (permeability and interactions with cationic peptides) of these membranes. On these data, an outer membrane model is proposed in which, as compared to other Gram-negatives, there is a stronger hydrophobic anchorage for the lipopolysaccharide, free lipids, porin proteins and lipoproteins, and a reduced surface density of anionic groups, which could be partially or totally neutralized by ornithine lipids. This model accounts for the permeability of Brucella to hydrophobic permeants and for its resistance to the bactericidal oxygen-independent systems of phagocytes.
Effect of Carbon Overcoat Implantation on the Magnetic and Structural Properties of Perpendicular Recording Media (2015)

Carbon overcoats play an important role in the corrosion protection of recording media used in hard disk drive technology. Filtered-cathodic vacuum arc (FCVA) has been studied in the past as a potential technology for depositing media overcoat. In order to achieve the desired property of FCVA carbon, it is essential to apply a suitable bias voltage, which results in an energetic carbon deposition on the magnetic layer of the recording media. In this paper, we focus our attention on the implantation effects of the energetic carbon on the magnetic and the structural properties of the recording media of two types, antiferromagnetically coupled and a single layer, in order to gain a meaningful insight on the implantation and its effect. The studies reveal that the energetic deposition alters the anisotropy constant of the magnetic layer, resulting in a reduction in the coercivity and the thermal stability factor.
Lipid Alterations in Lipid Rafts from Alzheimer's Disease Human Brain Cortex (2010)

Lipid rafts are membrane microdomains intimately associated with cell signaling. These biochemical microstructures are characterized by their high contents of sphingolipids, cholesterol and saturated fatty acids and a reduced content of polyunsaturated fatty acids (PUFA). Here, we have purified lipid rafts of human frontal brain cortex from normal and Alzheimer's disease (AD) and characterized their biochemical lipid composition. The results revealed that lipid rafts from AD brains exhibit aberrant lipid profiles compared to healthy brains. In particular, lipid rafts from AD brains displayed abnormally low levels of n-3 long chain polyunsaturated fatty acids (LCPUFA, mainly 22:6n-3, docosahexaenoic acid) and monoenes (mainly 18:1n-9, oleic acid), as well as reduced unsaturation and peroxidability indexes. Also, multiple relationships between phospholipids and fatty acids were altered in AD lipid rafts. Importantly, no changes were observed in the mole percentage of lipid classes and fatty acids in rafts from normal brains throughout the lifespan (24-85 years). These indications point to the existence of homeostatic mechanisms preserving lipid raft status in normal frontal cortex. The disruption of such mechanisms in AD brains leads to a considerable increase in lipid raft order and viscosity, which may explain the alterations in lipid raft signaling observed in AD.
Disposition of methadone in man after a single oral dose (1972)

The levels of methadone in the plasma and urine of 5 subjects giaven a single oral dose of 15 mg. have been determined using solvent extraction and gas‐liquid chromatography. Methadone was detected in plasma 30 minutes after drug administration. The peak plasma level occurred at 4 hours and was followed by an exponential decline during the next 20 hours. The mean apparent half‐life of methadone was 15 hours. The time action of methadone‐induced pupillary constriction closely coincided with the time course of methadone in plasma. An average of 52 per cent of the dose was excreted in the urine as methadone and metabolites in the 96 hours after drug administration. Nearly one half of the methadone and metabolites recovered in the urine was excreted during the first 24 hours. The renal clearance of methadone indicates that the drug is partially reabsorbed by a pH‐dependent process. These results demonstrate the importance of biotransformation and renal excretion as determinants of the disposition of methadone in man.
Technical standards for hepatitis B virus X protein (HBx) research (2014)

Chronic infection with hepatitis B virus (HBV) is a risk factor for developing hepatocellular carcinoma (HCC). The life cycle of HBV is complex and has been difficult to study because HBV does not infect cultured cells. The HBV regulatory X protein (HBx) controls the level of HBV replication and possesses an HCC cofactor role. Attempts to understand the mechanism(s) that underlie HBx effects on HBV replication and HBV-associated carcinogenesis have led to many reported HBx activities that are likely influenced by the assays used. This review summarizes experimental systems commonly used to study HBx functions, describes limitations of these experimental systems that should be considered, and suggests approaches for ensuring the biological relevance of HBx studies.

Inducible Tertiary Lymphoid Structures, Autoimmunity, and Exocrine Dysfunction in a Novel Model of Salivary Gland Inflammation in C57BL/6 Mice (2012)

Salivary glands in patients with Sjögren's syndrome (SS) develop ectopic lymphoid structures (ELS) characterized by B/T cell compartmentalization, the formation of high endothelial venules, follicular dendritic cell networks, functional B cell activation with expression of activation-induced cytidine deaminase, as well as local differentiation of autoreactive plasma cells. The mechanisms that trigger ELS formation, autoimmunity, and exocrine dysfunction in SS are largely unknown. In this article, we present a novel model of inducible ectopic lymphoid tissue formation, breach of humoral self-tolerance, and salivary hypofunction after delivery of a replication-deficient adenovirus-5 in submandibular glands of C57BL/6 mice through retrograde excretory duct cannulation. In this model, inflammation rapidly and consistently evolves from diffuse infiltration toward the development of SS-like periductal lymphoid aggregates within 2 wk from AdV delivery. These infiltrates progressively acquire ELS features and support functional GL7(+)/activation-induced cytidine deaminase(+) germinal centers. Formation of ELS is preceded by ectopic expression of lymphoid chemokines CXCL13, CCL19, and lymphotoxin-β, and is associated with development of anti-nuclear Abs in up to 75% of mice. Finally, reduction in salivary flow was observed over 3 wk post-AdV infection, consistent with exocrine gland dysfunction as a consequence of the inflammatory response. This novel model has the potential to unravel the cellular and molecular mechanisms that regulate ELS formation and their role in exocrine dysfunction and autoimmunity in SS.
Toner Charge Analysis Utilizing Charge Spectrometer (2008)

Many types of toner charge spectrometers have been designed because the measurement of toner charge distribution in an electrophotographic development system would be useful in evaluating and optimizing the system. However, some charge spectrometers cannot accurately measure the charge distribution; moreover, it is difficult to collect the toner particles classified by charge. We designed and manufactured a charge spectrometer using electrostatic field and gravity without air flow, which can classify the toner particles into different specific charge groups. The toner particles were analyzed by the particle analyzer measuring the composition and size of toner and additives. The analysis of a single-component toner showed that smaller sized toners with a large amount of additives resulted in a highly charged toner. The analysis method using the charge spectrometer and the particle analyzer together is very useful for studying the mechanism of toner charging and for producing a high-quality toner.
Stimulation of Ethylene Production in Tomato Tissue by Propionic Acid (1969)

Propionic acid (10(-3)m) increases ethylene production by about 30 to 60% in tissue from green and half-ripe tomatoes (Lycopersicon esculentum Mill. var. Homestead) but does not increase ethylene production in tissue from ripe fruit. Stimulation is not due to the conversion of propionic acid to ethylene but appears to be secondary in nature and to operate on the endogenous ethylene-forming system. Thus conversion of methionine to ethylene in green and half-ripe tomato tissue is increased in the presence of propionic acid. Inhibitors which affect the normal endogenous ethylene-forming system similarly affect the propionic acid-stimulated system. Endogenous propionic acid may play a role in the regulation of ethylene production in tomato tissues.

American Society for Enhanced Recovery and Perioperative Quality Initiative Joint Consensus Statement on Postoperative Gastrointestinal Dysfunction Within an Enhanced Recovery Pathway for Elective Colorectal Surgery (2017)

The primary driver of length of stay after bowel surgery, particularly colorectal surgery, is the time to return of gastrointestinal (GI) function. Traditionally, delayed GI recovery was thought to be a routine and unavoidable consequence of surgery, but this has been shown to be false in the modern era owing to the proliferation of enhanced recovery protocols. However, impaired GI function is still common after colorectal surgery, and the current literature is ambiguous with regard to the definition of postoperative GI dysfunction (POGD), or what is typically referred to as ileus. This persistent ambiguity has impeded the ability to ascertain the true incidence of the condition and study it properly within a research setting. Furthermore, a rational and standardized approach to prevention and treatment of POGD is needed. The second Perioperative Quality Initiative brought together a group of international experts to review the published literature and provide consensus recommendations on this important topic with the goal to (1) develop a rational definition for POGD that can serve as a framework for clinical and research efforts; (2) critically review the evidence behind current prevention strategies and provide consensus recommendations; and (3) develop rational treatment strategies that take into account the wide spectrum of impaired GI function in the postoperative period.
Electron paramagnetic resonance properties of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>n</mml:mi></mml:math>-type silicon in the intermediate impurity-concentration range (1975)

The EPR properties of phosphorus-doped silicon are investigated in detail for impurity concentrations $5\ifmmode\times\else\texttimes\fi{}{10}^{16}\ensuremath{\le}{N}_{D}\ensuremath{\le}1.6\ifmmode\times\else\texttimes\fi{}{10}^{18}$ ${\mathrm{d}\mathrm{o}\mathrm{n}\mathrm{o}\mathrm{r}\mathrm{s}/\mathrm{c}\mathrm{m}}^{3}$ and temperatures $1.1\ensuremath{\le}T\ensuremath{\le}35$ K. Particular care is taken to ensure that the inhomogeneously broadened spectra obtained correspond to well-defined experimental "passage cases." Rapid-passage and slow-passage spectra are converted into directly comparable "absorption envelope" forms which are convolutions of Lorentzian spin packets and Gaussian envelope functions. Spin-lattice relaxation times, spin-packet widths, and $g$ values are presented for both the hyperfine and broad-center-line (BCL) components of the spectra. The hyperfine-line spin-packet widths exhibit a concentration dependence and have magnitudes which are larger than those expected from spin-echo measurements of ${T}_{2}$. A previously unreported concentration dependence is also observed for the hyperfine-line $g$ value. Although similar $g$-value and spin-packet-width concentration dependences are noted for the BCL, the BCL parameters exhibit temperature dependences which are distinct from those observed for the corresponding hyperfine-line quantities. A comparison of the fractional spin susceptibility associated with the BCL and the results of a percolation calculation indicates that the BCL can be attributed to clusters of three or more interacting donor atoms. Evidence is also presented for a hyperfine-line spin-lattice relaxation process which proceeds through cross relaxation with fast relaxing cluster (BCL) centers. This process is shown to be consistent with the experimental temperature dependences of the BCL and hyperfine relaxation rates.
Transformer Type Accelerators for Intense Electron Beams (1971)

The principles and designs of transformer accelerators (TA) generating intense beams of charged particles over energy ranges 0.5-5 Mev are described. Pulse electron accelerators with pulse length of 10-8 to 10-5sec are investigated (some of them have a repetition rate of several hundreds pps) as well as one-phase d three-phase 50-cps transformers. The most models' power conversion efficiency is in the range of 60-95%, the averaged beam power comes up to or exceeds 10 kW and is in excess of 150 kW for one of the last models. The design of a 5 Mev single-pulse TA with peak current of 30 kA at pulse length of 40 nsec and of 1.2 Mev proton TA with average beam power of 10 kW are described. The features of main components of high voltage transformers and of intense current acceleration tubes are discussed.

Modular electron transfer circuits for synthetic biology (2010)

Electron transfer is central to a wide range of essential metabolic pathways, from photosynthesis to fermentation. The evolutionary diversity and conservation of proteins that transfer electrons makes these pathways a valuable platform for engineered metabolic circuits in synthetic biology. Rational engineering of electron transfer pathways containing hydrogenases has the potential to lead to industrial scale production of hydrogen as an alternative source of clean fuel and experimental assays for understanding the complex interactions of multiple electron transfer proteins in vivo. We designed and implemented a synthetic hydrogen metabolism circuit in Escherichia coli that creates an electron transfer pathway both orthogonal to and integrated within existing metabolism. The design of such modular electron transfer circuits allows for facile characterization of in vivo system parameters with applications toward further engineering for alternative energy production.

STRIKE: spectrally efficient fixed wireless network based on dual standards (2004)

One of the major challenges of the telecommunication community for the coming years will be to make multimedia services available to everyone, even to those who are in remote places. Broadband fixed wireless access (BFWA) is one of the best positioned radio access technologies to provide broadband access with performances that surpass current 3G mobile data rates and are similar to wired xDSL systems. The paper addresses the solutions which are proposed and demonstrated in the frame of the IST-STRIKE project to enhance spectral efficiency for BFWA and to guarantee end-to-end quality of service (QoS) through a dual mode HiperMAN/HiperLAN system. The first aspect is covered by the use of multi-transmit multi-receive (MTMR) techniques. Indeed, as it is foreseen that the data rates available with the studied standards will be sufficient for the majority of single user needs, the best way to increase the capacity and lower the deployment cost is to multiply the number of simultaneous transmissions. Besides, it is shown that to ensure QoS for high data rate and time constrained services (such as video streaming), interworking is provided at the data link control (DLC) level.
Theory and experiment on microstrip antennas with airgaps (1985)

In a microstrip antenna, the resonant frequency of a particular mode is determined by the shape and size of the conducting patch, the relative permittivity of the substrate and, to some extent, the thickness of the substrate. If the resonant frequency is to be changed, a new antenna is usually needed. Recently, Lee and Dahele have shown that the resonant frequencies of microstrip antennas can be changed by introducing an adjustable airgap between the substrate and the ground plane. In addition to providing a means for tuning the resonant frequencies, the airgap also has the effect of increasing the bandwidth of the antenna. The purpose of the paper is to present a comprehensive report on our research on microstrip antennas with airgaps. First, experimental results obtained by introducing an airgap in (i) circular-discs, (ii) annular-rings and (iii) dual-frequency stacked-disc microstrip antennas are presented. Secondly, the theories that have been developed are described. Thirdly, comparison between theoretical and experimental results is given.
Moiré: Formation and interpretation (1974)

The superposition of several periodic or quasiperiodic patterns produces moiré effects. In particular, the combination of three grid structures adds great flexibility to the use of moiré phenomena. Information about the fringe structure, given by vector addition in Fourier space, allows investigation of formations, interpretation, and expectation problems concerning moiré-pattern parameters. Any frequency and orientation of the pattern is possible, using three-line gratings. On the other hand, three quasiperiodic gratings with variations of frequency and/or orientation result in a zone-plate shape of the moiré pattern regardless of grating distortions. Both elliptical and hyperbolic zone plates occur. Several illustrations demonstrate these phenomena and indicate some potential applications.
