A multipath video streaming testbed for ad hoc networks (2003)

Enabling video transport over ad hoc networks is more challenging than over other wireless networks. The wireless links in an ad hoc network are highly error prone and can go down frequently because of node mobility, interference, channel fading, and the lack of infrastructure. However, the mesh topology of ad hoc networks implies the existence of multiple paths between two nodes. Indeed, multipath transport provides an extra degree of freedom in designing error resilient video coding and transport schemes. In our previous work, we propose schemes combining multistream coding with multipath transport, to show that path diversity provides an effective means to combat transmission error in ad hoc networks. In this paper, we report the implementation of a multiple path video streaming testbed using notebook computers and IEEE 802.11b cards, to validate the viability and performance advantages of these schemes. We implemented a layered coding with selective ARQ scheme and a multiple description motion compensation coding scheme in the testbed. The experimental results show that video transport is viable in ad hoc networks given careful cross-layer design. Combining multistream coding with MPT improves video quality, as compared to traditional schemes where a single path is used.
NMR solution structure and position of transportan in neutral bicelles (2004)

Isotropic bicelles are disc-shaped aggregates of lipids and detergents, and are suitable model systems for high-resolution NMR studies of membrane-interacting peptides. In this thesis the structures for the two peptides motilin and transportan were determined by homonuclear 1H methods in the presence of bicelles, and the structure of the bovine prion protein peptide (bPrPp) was solved in the presence of DHPC micelles. All of these peptides were found to be largely a-helical when bound to the model membranes. In subsequent experiments both motilin and transportan were shown to reside on the surface of the bicelles, whereas bPrPp is more likely to have a transmembrane configuration. NMR translational diffusion experiments revealed that the isotropic bicelles studied here are very large objects compared to what is regularly indicated by high-resolution NMR spectroscopy. Furthermore, these studies showed that all three peptides examined interact strongly with bicelles. Investigation of the NMR-relaxation of labeled sites in the peptides motilin and penetratin demonstrated that the overall rotational correlation times for these peptides do not reflect the bicellar size. Such decoupling of NMR relaxation from the dependence of overall size is also seen for the dynamics of the lipid molecules in the bicelles. It is therefore concluded that the overall size is not the sole determinant of the linewidths in NMR spectra, but that extensive motions within the bicelles also exert significant effects. Another interesting observation is that the membrane-bound structures of the peptides motilin, transportan, penetratin and bPrPp are very similar, even though these peptides have very different biological functions. In contrast, considerably more variation is observed in the membrane-positioning and molecular dynamics of these peptides. Since the bicelles have been found to induce differences in membrane positioning and molecular dynamics compared to micelles, these model membranes are likely to be important in order to enhance our understanding of the biological function of membrane interacting peptides.
Microtubule polarity and dynamics in the control of organelle positioning, segregation, and cytokinesis in the trypanosome cell cycle. (1995)

Trypanosoma brucei has a precisely ordered microtubule cytoskeleton whose morphogenesis is central to cell cycle events such as organelle positioning, segregation, mitosis, and cytokinesis. We have defined microtubule polarity and show the + ends of the cortical microtubules to be at the posterior end of the cell. Measurements of organelle positions through the cell cycle reveal a high degree of coordinate movement and a relationship with overall cell extension. Quantitative analysis of the segregation of the replicated mitochondrial genome (the kinetoplast) by the flagellar basal bodies identifies a new G2 cell cycle event marker. The subsequent mitosis then positions one "daughter" nucleus into the gap between the segregated basal bodies/kinetoplasts. The anterior daughter nucleus maintains its position relative to the anterior of the cell, suggesting an effective yet cryptic nuclear positioning mechanism. Inhibition of microtubule dynamics by rhizoxin results in a phenomenon whereby cells, which have segregated their kinetoplasts yet are compromised in mitosis, cleave into a nucleated portion and a flagellated, anucleate, cytoplast. We term these cytoplasts "zoids" and show that they contain the posterior (new) flagellum and associated basal-body/kinetoplast complex. Examination of zoids suggests a role for the flagellum attachment zone (FAZ) in defining the position for the axis of cleavage in trypanosomes. Progression through cytokinesis, (zoid formation) while mitosis is compromised, suggests that the dependency relationships leading to the classical cell cycle check points may be altered in trypanosomes, to take account of the need to segregate two unit genomes (nuclear and mitochondrial) in this cell.
Surface Plasmon Excitation and Surface-Enhanced Raman Scattering Using Two-Dimensionally Close-Packed Gold Nanoparticles (2009)

We investigated plasmon excitation and surface-enhanced Raman scattering (SERS) of crystal violet dye adsorbed on two-dimensionally (2D) close-packed gold nanostructures. With reference to the absorption maximum of colloidal nanoparticles, the 2D nanostructures showed red-shifted maxima at ∼560 and 740 nm. Interestingly, we found that the surface plasmon resonance (SPR) and SERS signals were preferentially enhanced near the edge of the 2D nanostructures. Both the SPR and SERS images suggest good correlation between the SPR-mediated localized electromagnetic field and the localized optical field, particularly near the edge of the 2D nanostructures. We observed broad SPR bands near the edge and red-shifted and intense bands near the center of the 2D nanostructures. Also, the overall SERS enhancement on the 2D nanostructures was comparable to that reported on engineered gold nanostructures. The integral SERS intensity near the edge was higher than that measured near the center. We carried out finite-different time-domain simulations and demonstrated that the experimental data are consistent with the simulated ones. Here, several proximal localization sites appeared for nanoparticles with their out-of-plane polarization parallel to the interparticle axis. Thus, the experimental results and the simulation predicted the existence of multipolar plasmon excitation and a narrow passage for energy percolation, which are often obscured in ensemble SERS measurements.

Bipolar Microwave Linear Power Transistor Design (1979)

Design considerations for n-p-n bipolar microwave linear power transistors are discussed. Optimization procedures are presented for determining emitter width for a specfic operation frequency, emitter ballasting resistance, and active area geometry based on calculated temperature distributions. A transistor chip designed for 4-GHz operations using these procedures achieved a linear power output of 27.5 dBm at a 1-dB compressed gain of 7 dB with a power added efficiency of 23 percent. Junction temperature rise was limited to 90/spl deg/C.
[Non-Hodgkin's lymphoma in the gastrointestinal tract]. (1991)

The gastrointestinal tract is the predominant site of extranodal non-Hodgkin's lymphoma. We present a summary of our recommendations as regards treatment. To avoid serious complications, such as perforation and/or bleeding, surgical resection should be considered before chemotherapy or radiation therapy. The laparotomy gives an opportunity to perform an exact staging procedure, including biopsy from the primary site and the lymph nodes. We recommend that gastrointestinal malignant lymphomas should be referred to medical centers with special competence in this field.
Enhanced Born Approximation for Wave Equations (2021)

We present an enhanced Born approximation inversion (EBAI) scheme for wave-like equations based on data to Born (DtB) algorithm. Due to multiple scattering, direct inversion methods usually perform poorly with artifacts in inverse scattering problems. By approximating the single scattering data through Taylor expansion, the DtB algorithm managed to remove the multiple scattering effects. Therefore, the nonlinearity between the scatterers and the scattering fields is unraveled. Without the optimization process usually needed for nonlinear inverse scattering problems, the EBAI scheme incorporating the DtB algorithm can achieve fast and accurate imaging. It is validated with 2D synthetic data.

ELECTRICAL PARAMETERS FOR SAFE AND EFFECTIVE ELECTRO-ACUPUNCTURE AND TRANSCUTANEOUS ELECTRICAL STIMULATION: THRESHOLD POTENTIALS FOR TINGLING, MUSCLE CONTRACTION AND PAIN; AND HOW TO PREVENT ADVERSE EFFECTS OF ELECTRO-THERAPY PART I (1985)

10 Essential electrical parameters for safe and effective electrical stimulation was discussed. Among them, especially importance of rise and fall time which influence capacitive current (Ic = C X dv/dt), pulse duration and output impedance for (+) and (-) polarities was emphasized. When comparing one pulse component with high amplitude with the other pulse component with low amplitude in the same stimulation pulse complex of the same electrical stimulator, effective stimulation voltage delivered to the body can be larger with the low amplitude pulse component if it has much lower output impedance than the other. When pulse repetition rate is higher than several pulses/sec., in spite of increase in pain threshold, microcirculation is often interfered with and as a result the effect will not last long after each treatment. Our studies indicate that optimal pulse repetition rate is about the same as heart rate synchronized with local circulation. Tingling threshold is a more reproducible reliable parameter than pain threshold in study of pain. Measurement of threshold potentials for tingling sensation, muscle contraction, along with pain threshold is extremely important in the same patient. Phenomena of short circuits between the nerve fibers responsible for tingling sensation and nerve fibers responsible for pain sensation is described.
Thiophene synthesis and distribution in young developing plants ofTagetes patulaandTagetes erecta (1994)

Thiophene synthesis and accumulation were investigated in organs of Tagetes patula and T. erecta. Thiophene accumulation started rapidly in germinating seedlings of both species. Roots and hypocotyls were the major thiophene accumulating organs and 5-(3-buten-1-ynyl)-2, 2-bithienyl (BBT) and 5-(4-acetoxy-1-butynyl)-2, 2 -bithienyl (BBTOAc) were the major accumulated compounds. Higher thiophene concentrations were reached in Tagetes patula than in T. erecta. Accumulation patterns for individual thiophenes were different within organs, between organs and between both species. Within hypocotyls of Tagetes patula, thiophene concentrations were high in the epidermis and the vascular tissue and low in the parenchymatic tissues of cortex and pith. Synthesis of thiophenes was high in the roots and hypocotyls and very low in the leaves. Transport of thiophenes from the roots into the shoot occurred, but the rate of transport was too low to explain the high concentrations in the hypocotyl. It is concluded that for the main part thiophenes are accumulated where they are synthesized.
Analysis of performance measures of flexible manufacturing system (2011)

Flexible manufacturing system (FMS) is a highly integrated manufacturing system. The relation between its components is very complex. The mathematical programming approaches are very difficult to solve for very complex system so the simulation of FMS is widely used to analyze its performance measures. Also the FMS components are very sophisticated and costly. If FMS has to be implemented then it is better to analyze its results using simulation which involves no loss of money, resource and labor time. As a typical discrete event system FMS have been studied in such aspects as modeling and performance analysis. In this paper, a concept and implementation of the Petri nets for measuring and analysis of performance measures of FMS is applied. Also the system has been modeled in Visual Slam software, i.e. AweSim. The other well defined mathematical technique, i.e. bottleneck technique has also been applied for the purpose of comparison and verification of the simulation results. An example FMS has been taken into consideration and its Petri net model, AweSim model, and mathematical model has been constructed. Several performance measures have been used to evaluate system performance. And it has been found that the simulation techniques are easy to analyze the complex flexible manufacturing system.
ANALYSIS OF SINGLE POINT MOORED TANKER USING MANOEUVRING HYDRODYNAMIC MODEL (1995)

This paper deals with the dynamic behaviour of the Single Point Mooring System (SPM) of moored vessels considering the influence of environmental forces as well as shallow water effects. A nonlinear mathematical model is developed for the simulation of low speed ship manoeuvres (Takashina, 1986) is extended to study the behaviour of a tanker moored to a single buoy in comparison with Obokata's model (1987). A large number of tanker motion simulations were carried out both for deep and shallow water and different environmental conditions. The influence of the system parameters shown by the study is, in general, in good agreement with those obtained by traditional SPM system analysis.
Influence of Me2SO and incubation time on papain activity studied using fluorogenic substrates. (2001)

Papain activity in a buffer containing Me2SO was studied using fluorogenic substrates. It was found that the number of active sites of papain decreases with increasing Me2SO concentration whereas the incubation time, in a buffer containing 3% Me2SO does not affect the number of active sites. However, an increase of papain incubation time in the buffer with 3% Me2SO decreased the initial rate of hydrolysis of Z-Phe-Arg-Amc as well as Dabcyl-Lys-Phe-Gly-Gly-Ala-Ala-Edans. Moreover, an increase of Me2SO concentration in working buffer decreased the initial rate of papain-catalysed hydrolysis of both substrates. A rapid decrease of the initial rate (by up to 30%) was observed between 1 and 2% Me2SO. Application of the Michaelis-Menten equation revealed that at the higher Me2SO concentrations the apparent values of k(cat)/Km decreased as a result of Km increase and kcat decrease. However, Me2SO changed the substrate binding process more effectively (Km) than the rate of catalysis k(cat).
Microstrip-fed quasi-Yagi antenna with broadbandcharacteristics (1998)

A compact and uniplanar antenna with broadband characteristics is presented. The novel Yagi-like printed dipole array antenna is fed by a microstrip-to-coplanar strip transition, and uses the truncated microstrip ground plane as its reflecting element. An X-band prototype measures a bandwidth of 17%, with 6.5 dB gain, 18 dB front-to-back ratio, and lower than –15 dB cross-polarisation level at 10 GHz.
Duration of Anticoagulant Therapy After First Episode of Venous Thrombosis in Patients With Inherited Thrombophilia (1997)

PATIENTS WITH acute venous thrombosis or pulmonary embolism (PE) (venous thromboembolism [VTE]) are at high risk of recurrence unless they are treated with an adequate course of anticoagulants.<sup>1,2</sup>Anticoagulant therapy is very effective for the treatment of VTE but is associated with bleeding.<sup>3</sup>The risk of recurrence is highest early after the acute episode and then declines over time. Ideally, treatment should be continued until the benefits of treatment are offset by the risks, but this optimal duration is uncertain because both the risk of recurrence after discontinuing treatment and the risk of bleeding during anticoagulation therapy are not easily predicted in individual patients. For most patients, the benefits of 3 to 6 months of anticoagulant therapy greatly outweigh the risks.<sup>1,4</sup>In addition, some patients, for example those with familial thrombophilia, remain at high risk for recurrence even after completing such a course of anticoagulants<sup>5,6</sup>; consequently,
Intramedullary penetrance of metrizamide in the dog spinal cord. (1981)

Metrizamide computed tomography (CT) myelography is clinically useful in the detection of syringohydromyelia. The mechanism by which intrathecally injected metrizamide migrates into the intramedullary cavity is unknown, although reflux into the central canal of the cord via the obex has been postulated. Since intrathecally injected metrizamide has been shown to penetrate normal brain, similar penetrance of the spinal cord might be expected. Five anesthetized mongrel dogs were examined with sequential CT scanning of the cervical spine for 24 hr after intrathecal introduction of metrizamide. The attenuation values of the specified subarachnoid space and the spinal cord at the level of the atlantoaxial joint were recorded. A significant and reproducible increase with time in attenuation values within the cervical spinal cord accompanied by a progressive decrease in attenuation values of the subarachnoid space was observed. The proposed mechanism of cord enhancement, the implication for cord imaging, and the analysis of patients with syringohydromyelia are discussed.

Insights from Crystallographic Studies into the Structural and Pairing Properties of Nucleic Acid Analogs and Chemically Modified DNA and RNA Oligonucleotides (2007)

Chemically modified nucleic acids function as model systems for native DNA and RNA; as chemical probes in diagnostics or the analysis of protein-nucleic acid interactions and in high-throughput genomics and drug target validation; as potential antigene-, antisense-, or RNAi-based drugs; and as tools for structure determination (i.e., crystallographic phasing), just to name a few. Biophysical and structural investigations of chemically modified DNAs and RNAs, particularly of nucleic acid analogs with more significant alterations to the well-known base-sugar-phosphate framework (i.e., peptide or hexopyranose nucleic acids), can also provide insights into the properties of the natural nucleic acids that are beyond the reach of studies focusing on DNA or RNA alone. In this review we summarize results from crystallographic analyses of chemically modified DNAs and RNAs that are primarily of interest in the context of the discovery and development of oligonucleotide-based therapeutics. In addition, we re-examine recent structural data on nucleic acid analogs that are investigated as part of a systematic effort to rationalize nature's choice of pentose in the genetic system.
