Data mining framework for video data (2010)

Content-based video analyzing and retrieval are important technologies, which have been an international research focus in recent ten years. It is needed urgently the advanced technologies for organizing, analyzing, representing, indexing, filtering, retrieving and mining the vast amount of videos to retrieve specific information based on video content effectively, and to provide better ways for entertainment and multimedia applications. Although numerous papers have been published on data mining few of them deal with video mining is focusing on low features, such as color, texture, audio and motion. Due to the inherent complexity of video data, existing data mining algorithms and techniques cannot be used directly in video. In this paper we try to focus new mining techniques designed to facilitate the video data mining process.
Detoxification of an immunogenic fraction from a culture filtrate of <i>Pseudomonas aeruginosa</i> (1969)

SUMMARY Mice immunized with a fraction from a culture filtrate of Ps. aeruginosa , then burned and infected with virulent serotypes of Ps. aeroginosa , were protected from septicaemia and death. The immunogenic fraction killed mice at dosages 400 times those of the minimum protective dosages. Treatment of the immunogenic fraction with 0·5% formalin reduced its lethal effect for mice and slightly improved its immunizing potency so that the difference between the smallest immunizing dose used and the smallest amount that killed mice was more than 80,000 doses.
Encapsulation of drugs by lyophilized empty dipalmitoylphosphatidylcholine liposomes: Effect of calcium ion. (1989)

The effects of divalent cation (Ca2+) on the characteristics of dipalmitoylphosphatidylcholine (DPPC) liposomes regenerated from lyophilized empty liposomes by rehydration and warming were investigated. The results showed that the volume (ml) of internal aqueous compartment per g lipid (captured volume; Vcap) has a maximum at a certain concentration range of calcium chloride and the maximal value is more than ten times the minimal value. This phenomenon can be explained by considering that binding of Ca2+ to phosphate groups in DPPC molecules induces an increase in the distance (r) between adjacent bilayer membranes in multilamellar liposomes through electrostatic force and causes an increase in Vcap. The dynamic properties of lyophilized liposomes in the rehydration process were examined using a multilamellar vesicle model. The results of simulation suggested that a repulsive force induced between the adjacent bilayer membranes causes rearrangement of the constituent lipid molecules in a liposome followed by an increase in the distance r, a decrease in the internal lamellar number, a smaller increase in liposome size and finally a significant increase in Vcap.
Compressibilities of aqueous tert-butanol in the water-rich region at 25°C: Partial molar fluctuations and mixing schemes (1999)

We measured the speeds of sound, u, and the densities, d, and, hence, determined the adiabatic compressibilities, κS, of aqueous tert-butanol (TBA) at small increments in mole fraction of TBA, xTBA. Existing data for heat capacity, Cp, and thermal expansivity, αp, were used to convert κS to the isothermal compressibilities, κT. Using these κT data, the normalized volume fluctuations, VΔ, and their composition derivative, the partial molar volume fluctuations of TBA, VΔTBA, (Y. Koga and P. Westh, Bull. Chem. Soc. Jpn., 1996, 69, 1505) were calculated. By using Cp data available in the literature we also calculated the normalized entropy fluctuations, SΔ, and the partial molar entropy fluctuations of TBA, SΔTBA. Furthermore, the density data at 15, 25 and 35°C in the literature were used to evaluate the thermal expansivities, αp, from which the normalized cross (entropy–volume) fluctuations, SVΔ, and the partial molar cross-fluctuations of TBA, SVΔTBA, were calculated. The composition dependence of these fluctuation functions were interpreted in the light of the mixing schemes in aqueous solutions of TBA and other non-electrolytes and the transition between them (Y. Koga, J. Phys. Chem., 1996, 100, 5172).
Adsorption of a Single-or a Double-Chained Anionic Surfactant and Poly (vinylpyrrolidone) on Alumina from Their Binary Mixtures (1994)

Adsorption of a single-or a double-chained anionic surfactant and poly (vinylpyrroli-done) (PVP) on alumina from their binary aqueous mixtures has been characterized by measuring adsorbed amount and ESR. Lithium dodecyl sulfate (LiDS) and sodium bis (2-ethylhexyl) sulfosuccinate (Aerosol OT) are used as a single-and a double-chained surf actants, respectively. Under a constant feed concentration of PVP, the adsorption of PVP increases remarkably and then decreases with LiDS concentration, while the adsorption of PVP also increases sharply at low Aerosol OT concentration and then gradu-ally decreases with Aerosol OT concentration. The magnitude in the enhancement of PVP adsorption is significantly greater for Aerosol OT than for LiDS. Furthermore, the ESR spectra using a spin-labeled polymer suggest that the conformation of PVP adsorbed takes greater portion of train segments by the coadsorption of Aerosol OT than by LiDS when (equilibrium concentration/critical micelle concentration) is below unity.
Fast Face Localisation and Verification. (1997)

We propose a method for fast face localisation and verification (identification) based on a robust form of correlation. Geometric and photometric normalisation of face images is achieved by direct minimisation. During optimisation, the correlation is estimated from a set of samples drawn from a Sobol sequence. This Monte-Carlo technique speeds the evaluation of correlation approximately twenty five times and makes the optimisation process near-real time. In recognition experiments, the optimised robust correlation outperformed two standard techniques based on the Dynamic Link Architecture [11]. 1 Introduction Personal identification (authentication, verification of identity) is an important issue in many security applications. In this paper we focus on personal identification from frontal face images. Identification is closely related to recognition, but differs in at least three fundamental aspects. Firstly, a client -- an authorised user of a personal identification system -- is ass...
A New Improved Rectifier For Standard Telecom Systems (2005)

Switch-room power is the keyword for modern telecom power plants. Common requirements are low EMI, high power factor, low THD, redundancy and natural convection cooling. This paper describes a new rectifier that is designed with these requirements in mind. State-of-the-art topologies are used to achieve an efficiency of 92% while still fulfilling EN 55 022 class B conducted and radiated. A wide input voltage range is accepted and high transients are tolerated. The paper also describes the advantage of constant power control and it is shown how 1600W over the full output voltage range is achieved. The rectifier is cooled in a novel way. It is shown how an optimized heat sink integrated with an innovative tilting design decreases the volume of the rectifier and allows more rectifiers per cabinet.
Genetic Variability in Flower Attractiveness to Honeybees (Apis mellifera L.) within the Genus Citrullus (1999)

Fruit and seed set in insect-pollinated agricultural crops rely primarily on honeybees because of their ease of management and transportation. In many fruit and vegetable crops, the number of bee visitations can be the limiting step in obtaining optimal yield. Increasing the attractiveness of flowers to honeybees could, therefore, provide a useful means of improving fruit yield and seed production. Genetic variability in attractiveness to honeybees was found within the genus Citrullus . The number of daily visits per flower ranged from six to 12 among cultivars. Moreover, most of the visits to the more attractive cultivars occurred in the first hour of bee activity, whereas visits to the less attractive cultivars started later in the morning. A positive relationship was found between the frequency of bee visitations and seed number per fruit. Analyses of floral attributes indicated no genetic variability in flower size, amount of pollen grains, or nectar volume; however, differences were observed in the concentration of sucrose and total sugars in the nectar. A positive relationship was found between attractiveness to bees and nectar sugar concentration, suggesting that this characteristic is one of the parameters responsible for variability in attractiveness to honeybees.
Compact and Accurate 3-D Face Modeling Using an RGB-D Camera: Let's Open the Door to 3-D Video Conference (2013)

We present a method for producing an accurate and compact 3-D face model in real time using a low cost RGB-D sensor like the Kinect camera. We extend and use Bump Images for highly accurate and low memory consumption 3-D reconstruction of the human face. Bump Images are generated by representing the Cartesian coordinates of points on the face in the spherical coordinate system whose origin is the center of the head. After initialization, the Bump Images are updated in real time with every RGB-D frame with respect to the current viewing direction and head pose that are estimated using the frame-to-global-model registration strategy. While high accuracy of the representation allows to recover fine details, low memory use opens new possible applications of consumer depth cameras such as 3-D video conferencing. We validate our approach by quantitatively comparing our result with the result obtained by a commercial high resolution laser scanner. We also discuss the potential of our proposed method for a 3-D video conferencing application with existing internet speeds.
Regulation of single sodium channels in renal tissue: a role in sodium homeostasis. (1986)

The kidney is responsible for the maintenance of an organism's body solute and water balance (i.e., Na+ homeostasis). The distal nephron and the cortical collecting duct (CCD) (an example of a tight epithelium) are important sites of regulatory control over the rate of Na+ reabsorption. The Na+ channel, a specialized protein located in the apical membrane of CCD cells, is the specific site of transepithelial Na+ movement. Na+ entry into the cell across the apical membrane occurs by passive diffusion of Na+ down an electrochemical gradient. We have used the patch-voltage clamp method to examine single-channel conductance events of the amiloride-sensitive apical Na+ channel in A6 cells, a model of CCD. Two types of Na+ channel were identified. One type was characterized by low selectivity (Na+ to K+) and high conductance, the other by high selectivity and low conductance. The type and frequency of channel observed depended on the transporting state of the epithelium. In a tissue with poor transport rates, the low-selectivity type of channel was prevalent (the other type of channel was present, but in a very low density). Therefore, the poorly transporting tissue had an overall low apical Na+ conductance. In a tissue with high transport rates, the highly selective channel appeared to be predominant. In this case the net result was a highly Na+ conductive apical membrane.
Wedge Waveguides and Resonators for Quantum Plasmonics (2015)

Plasmonic structures can provide deep-subwavelength electromagnetic fields that are useful for enhancing light-matter interactions. However, because these localized modes are also dissipative, structures that offer the best compromise between field confinement and loss have been sought. Metallic wedge waveguides were initially identified as an ideal candidate but have been largely abandoned because to date their experimental performance has been limited. We combine state-of-the-art metallic wedges with integrated reflectors and precisely placed colloidal quantum dots (down to the single-emitter level) and demonstrate quantum-plasmonic waveguides and resonators with performance approaching theoretical limits. By exploiting a nearly 10-fold improvement in wedge-plasmon propagation (19 μm at a vacuum wavelength, λvac, of 630 nm), efficient reflectors (93%), and effective coupling (estimated to be >70%) to highly emissive (~90%) quantum dots, we obtain Ag plasmonic resonators at visible wavelengths with quality factors approaching 200 (3.3 nm line widths). As our structures offer modal volumes down to ~0.004λvac(3) in an exposed single-mode waveguide-resonator geometry, they provide advantages over both traditional photonic microcavities and localized-plasmonic resonators for enhancing light-matter interactions. Our results confirm the promise of wedges for creating plasmonic devices and for studying coherent quantum-plasmonic effects such as long-distance plasmon-mediated entanglement and strong plasmon-matter coupling.
Human Usher 1B/mouse shaker-1: the retinal phenotype discrepancy explained by the presence/absence of myosin VIIA in the photoreceptor cells (1996)

Usher syndrome type 1 (USH1) associates severe congenital deafness, vestibular dysfunction and progressive retinitis pigmentosa leading to blindness. The gene encoding myosin VIIA is responsible for USH1B. Mutations in the murine orthologous gene lead to the shaker-1 phenotype, which manifests cochlear and vestibular dysfunction, without any retinal defect. To address this phenotypic discrepancy, the expression of myosin VIIA in retinal cells was analyzed in human and mouse during embryonic development and adult life. In the human embryo, myosin VIIA was present first in the pigment epithelium cells, and later in these cells as well as in the photoreceptor cells. In the adult human retina, myosin VIIA was present in both cell types. In contrast, in mouse, only pigment epithelium cells expressed the protein throughout development and adult life. Myosin VIIA was also found to be absent in the photoreceptor cells of other rodents (rat and guinea-pig), whereas these cells expressed the protein in amphibians, avians and primates. These observations suggest that retinitis pigmentosa of USH1B results from a primary rod and cone defect. The USH1B/shaker-1 paradigm illustrates a species-specific cell pattern of gene expression as a possible cause for the discrepancy between phenotypes involving defective orthologous genes in man and mouse. Interestingly, in the photoreceptor cells, myosin VIIA is mainly localized in the inner and base of outer segments as well as in the synaptic ending region where it is co-localized with the synaptic vesicles. Therefore, we suggest that myosin VIIA might play a role in the trafficking of ribbon-synaptic vesicle complexes and the renewal processes of the outer photoreceptor disks.
Sir, Please Step Away from the ASR-33! (2010)

One of the naughty details of my Varnish software is that the configuration is written in a domain-specific language that is converted into C source code, compiled into a shared library, and executed at hardware speed. That obviously makes me a programming language syntax designer, and just as obviously I have started to think more about how we express ourselves in these syntaxes.
Nonlinear, dispersion-free 10 GHz optical pulse train transmission in distributed erbium-doped fibre (1991)

The transmission of a 10 GHz repetition rate optical pulse train over a 28.5 km long distributed erbium-doped fibre amplifier is reported. In the linear dispersion regime, the pulses broaden so that the tails of adjacent pulses overlap. However, given sufficiently high signal powers, the optical Kerr effect causes pulse narrowing back to the original 18 ps pulsewidth.
Pneumatic Actuators for Climbing, Walking and Serpentine Robots (2007)

Pneumatic actuators originally limited to simple motion between two hard stops, are now becoming more and more popular, and substituting in many cases electric drives. Especially robots intended to contact with ground, obstacles, co-operating with other robots and humans require drives strong, compliant and safe. We have shown a few projects of quite different machines, all taking benefits from various pneumatic drives. But this chapter does not cover all important areas of possible applications for pneumatics. Actuators with high power/weight ratio are needed in mechanical systems that support human motion in rehabilitation, welfare, and sports. Moreover, mechanical systems for entertainment requires various, smooth motions. Actuators applied to these systems also should have high power/weight ratio. From biology we know that all animals, try to move in an energy efficient way. The important mechanisms available are muscles and tendons which make energy recuperation possible. For example, the Achilles tendon in a human leg can store up to one third of the motionâ€™s energy during running. The muscular system is capable of adapting stiffness characteristics in order to move in a wide range of different walking and running patterns and still exploit the passive behavior of the actuation system. This is why in the very first jumping robots thrust was generated by pneumatic actuator (Raibert, 1986). In this area we focus our investigations on the aspect of changing mechanical impedance of driving system and its influence on features of a jump (Jezierski & Granosik, 2007). Pneumatic drives can be combined with electric motors like in Distributed Macro Mini (DM2) Actuation concept (Zinn et al., 2004) producing hight performance and low impedance human safe actuator. We also plan to use pneumatic elements for suspension of just beeing designed serpentine robot Wheeeler (Pytasz & Granosik, 2007).
Cranial Electrotherapy Stimulation for the Treatment of Depression (2010)

More prevalent in women than men, clinical depression affects approximately 15 million American adults in a given year. Psychopharmaceutical therapy accompanied by psychotherapy and wellness interventions (e.g., nutrition, exercise, counseling) is effective in 80% of diagnosed cases. A lesser known adjunctive therapy is that of cranial electrotherapy stimulation (CES). The major hypothesis for the use of CES in depression is that it may reset the brain to pre-stress homeostasis levels. It is conjectured that the pulsed electrical currents emitted by cranial electrical stimulators affect changes in the limbic system, the reticular activating system, and/or the hypothalamus that result in neurotransmitter secretion and downstream hormone production. While evidence is good for applied research, basic research about the mechanisms of action for CES remains in its infancy. A review of the literature provides an overview of current research findings and implications for clinical mental health practice.
Isolation and characterization of mitochondrial acyl‐coa: Glycine n‐acyltransferases from kidney (1993)

When bovine kidney mitochondria were assayed in the presence of Triton X-100, they were found to contain glycine N-acyltransferase activity toward the CoA-adducts of benzoate, butyrate, isovalerate, naphthylacetate, phenylacetate, and salicylate. Heptanoyl-CoA activity was masked by high acyl-CoA hydrolase activity. All activities found in detergent-lysed mitochondria, and also that toward heptanoyl-CoA, could be released in soluble form by repeated cycles of freeze-thawing. Activity in the particle-free lysate decreased in the order: phenylacetyl-CoA > benzoyl-CoA > salicylyl-CoA > butyryl-CoA > naphthylacetyl-CoA > heptanoyl-CoA > isovaleryl-CoA. This is quite different from liver, where the activity toward the arylacetic acids is much lower and the other activities are higher. This reflects a major difference in the relative expression of the aralkyl and arylacetyl transferases between liver and kidney. The phenylacetyl-CoA and naphthylacetyl-CoA activity purified with a single protein which is termed the arylacetyl transferase. This enzyme was similar to the hepatic arylacetyl transferase in terms of its sensitivity to sulfhydryl reagents, response to cations, and molecular weight (33,500). Activity toward benzoyl-CoA also purified as a single form which was similar to the hepatic form in its molecular weight (34,000), response to cations, and kinetic properties. Conditions leading to the inhibition of this kidney form and also the hepatic form by p-mercuribenzoate are described.

Methods discussed were selected for accuracy and predictabililty.
The Mathematical Model of the Chemical Phase of Radiobiological Mechanism (2005)

Abstract. Understanding radiobiological mechanism is important in the protection of cells against ionizing radiation as well as in the treatment of tumors. The ionizing particles transfer their energy to surrounding medium and important biological reactions may occur in biological objects (cells). Mathematical modelling and computer simulation of the given processes play a key role in a study of such processes. This article describe chemical processes running in water solutions after the impact of ionizing particles. A simplifield mathematical model is introduced. It can be used to better analyze the role of individual substances (e.g. oxygen) in physically chemical phase of radiobiological mechanism. For simplicity, only four chemical reactions are considered in the model. Finally, in the article are present formulas for probabilities of strand breaks of DNA molecules.
A Programmable Lattice-Reduction Aided Detector for MIMO-OFDMA (2008)

This paper presents the first programmable Lattice- Reduction Aided (LRA) symbol detector for Multiple-Input Multiple-Output (MIMO) and Orthogonal Frequency Division Multiple Access (OFDMA). The detector proposed is implemented using 65 nm ASIC technologies. Owing to the programmability, the detector can be dynamically switched between linear (e.g. MMSE) and lattice-reduction aided (e.g. LRA-MMSE) detectors by simply running another software subroutine. Therefore, it allows a good trade-off between performance and computational latency to be achieved under various scenarios. Along with the hardware, two algorithm simplifications (SCNT-LR and SOT-LR) are proposed for finding subcarriers with ill- conditioned channel matrices. And in the end, interpolated LR (I- LR) is proposed to further reduce the computational complexity for real-time implementations.
Work flow analysis (1993)

We present a new approach to the study of work flows in organizations. Using well-known modeling paradigms and existing computer-based tools, we show how to rapidly model and analyze complex work structures to improve throughput and resource utilization. The specification of a work flow is done using IDEFO (SADT), extended with behavioral details. We have developed a program (Work Flow Analyzer) that processes the resulting model to automatically generate a Colored Petri Net (CP-net) complete with the logic for loading input files and printing reports about processing bottlenecks and idle resources. This greatly reduces the cost and time to use simulation.
