On compact routing for the internet (2007)

The Internet's routing system is facing stresses due to its poor fundamental scaling properties. Compact routing is a research field that studies fundamental limits of routing scalability and designs algorithms that try to meet these limits. In particular, compact routing research shows that shortest-path routing, forming a core of traditional routing algorithms, cannot guarantee routing table (RT) sizes that on all network topologies grow slower than linearly as functions of the network size. However, there are plenty of compact routing schemes that relax the shortest-path requirement and allow for improved, sublinear RT size scaling that is mathematically provable for all static network topologies. In particular, there exist compact routing schemes designed for grids, trees, and Internet-like topologies that offer RT sizes that scale logarithmically with the network size. In this paper, we demonstrate that in view of recent results in compact routing research, such logarithmic scaling on Internet-like topologies is fundamentally impossible in the presence of topology dynamics or topology-independent (flat) addressing. We use analytic arguments to show that the number of routing control messages per topology change cannot scale better than linearly on Internet-like topologies. We also employ simulations to confirm that logarithmic RT size scaling gets broken by topology-independent addressing, a cornerstone of popular locator-identifier split proposals aiming at improving routing scaling in the presence of network topology dynamics or host mobility. These pessimistic findings lead us to the conclusion that a fundamental re-examination of assumptions behind routing models and abstractions is needed in order to find a routing architecture that would be able to scale "indefinitely.
Sputtered Si:H alloys for edge filters: application to thermophotovoltaics (2002)

Si:H alloys are being investigated for the high-index material in an interference filter to provide spectral control in an application of thermophotovoltaic energy conversion. In particular, a multilayer edge filter is being developed to provide high transmission of photons with wavelengths between 1.0 and 2.4 microm and high reflectance for wavelengths outside this range. Thin films of Si:H were deposited by means of rf reactive sputtering. Deposition parameters were varied to optimize the H content in Si:H coatings such that the refractive index was greater than 3. Optical absorption near 1 microm and Si:H infrared absorptions near 5 and 12 microm were minimized.
Morphology and compression behaviour of biodegradable scaffolds produced by the sintering process (2008)

Porous poly(L-lactic acid) (PLA) scaffolds of 85 per cent and 90 per cent porosity are prepared using polymer sintering and porogen leaching method. Different weight fractions of 10 per cent, 30 per cent, and 50 per cent of hydroxyapatite (HA) are added to the PLA to control the acidity and degradation rate. The three-dimensional (3D) morphology and surface porosity are tested using micro-computer tomography (micro-CT), optical microscopy, and scanning electron microscopy (SEM). Results indicate that the surface porosity does not change on the addition of HA. The micro-CT examinations show a slight decrease in the pore size and increase in the wall thickness accompanied by reduced anisotropy for the scaffolds containing HA. Scanning electron micrographs show detectable interconnected pores for the scaffold with pure PLA. Addition of the HA results in agglomeration of the HA particles and reduced leaching of the porogen. Compression tests of the scaffold identify three stages in the stress-strain curve. The addition of HA results in a reduction in the modulus of the scaffold at the first stage of elastic bending of the wall, but this is reversed for the second and third stages of collapse of the wall and densification in the compression tests. In the scaffolds with 85 per cent porosity, the addition of a high percentage of HA could result in 70 per cent decrease in stiffness in the first stage, 200 per cent increase in stiffness in the second stage, and 20 per cent increase in stiffness in the third stage. The results of these tests are compared with the Gibson cellular material model that is proposed for prediction of the behaviour of cellular material under compression. The pH and molecular weight changes are tracked for the scaffolds within a period of 35 days. The addition of HA keeps the pH in the alkaline region, which results in higher rate of degradation at an early period of observation, followed by a reduced rate of degradation later in the process. The final molecular weight is higher for the scaffolds with HA than for scaffolds of pure PLA. The manufactured scaffolds offer acceptable properties in terms of the pore size range and interconnectivity of the pores and porosity for non-load-bearing bone graft substitute; however, improvement to the mixing of the phases of PLA and HA is required to achieve better integrity of the composite scaffolds.

Extent of Resection of Glioblastoma Revisited: Personalized Survival Modeling Facilitates More Accurate Survival Prediction and Supports a Maximum-Safe-Resection Approach to Surgery (2014)

Nonlinear, multivariable AFT modeling outperforms current methods for estimating individual survival after glioblastoma resection. The model produces personalized survival curves and quantifies the relationship between variables modulating patient-specific survival. This approach provides comprehensive, personalized, probabilistic, and clinically relevant information regarding the anticipated course of disease, the overall prognosis, and the patient-specific influence of EOR and adjuvant chemoradiotherapy. The continuous, nonlinear relationship identified between expected median survival and EOR argues against a surgical management strategy based on rigid EOR thresholds and instead provides the first explicit evidence supporting a maximum safe resection approach to glioblastoma surgery.
Soybean Resistance to Soybean Cyst Nematode Race 3 Is Conditioned by an Additional Dominant Gene (1992)

Inheritance of resistance in soybean [ Glycine max (L.) Merr.] soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is complex. The objectives of this study were to determine (i) inheritance Race 3 resistance in ‘Peking’ and PI 90763 and (ii) the relationship Rhg4 and of any other genes occurring in Peking to those genes found in PI 88788 for SCN resistance. The F 1 , F 2 , and F 3 plants from five different crosses among resistant (R) and susceptible (S) cultivars evaluated for SCN resistance in the greenhouse. Individual plants were categorized as resistant or susceptible based on the index of parasitism. The chi‐square test was used to determine goodness of fit between observed and expected ratios. The results indicated that SCN Race 3 resistance was conditioned by one dominant and two recessive genes in each parent. Peking and PI 90763 have all three resistance genes in common. Two genes, Rhg 4 and rhg z , in both Peking and in PI 90763 were also in P1 88788. An additional dominant gene in PI 88788 and a second recessive gene in Peking and in PI 90763 provided nonallelic interaction.
Hypoglycemic effect of Prunus amygdalus seeds in albino rabbits. (1997)

On administration of 2.5 g almond seed and its proportionate fractions, viz. 1.22 g defatted seed and 1.28 g oil to three groups of albino rabbits, they showed a definite hypoglycemic action during a two months study. The active factor seems to be a non oil fraction which is only partly soluble in ethyl ether.
An ART2-BP neural net and its application to reservoir engineering (2002)

Backpropagation feedforward neural networks have been applied to pattern recognition and classification problems. However, under certain conditions the backpropagation net classifier can produce nonintuitive, nonrobust and unreliable classification results. The backpropagation net is slower to train and is not easy to accommodate new data. To solve the difficulties mentioned above, an unsupervised/supervised type neural net, namely, ART-BP net, is proposed. The idea is to use a low vigilance parameter in ART2 net to categorize input patterns into some classes and then utilize a backpropagation net to recognize patterns in each class. Advantages of the ART2-BP neural net include (1) improvement of recognition capability, (2) training convergence enhancement, and (3) easy to add new data. Theoretical analysis along with a well testing model recognition example are given to illustrate these advantages.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Assessing the Placement of a Cochlear Electrode Array by Multidimensional Scaling (2011)

Correct placement of the electrode is crucial for cochlear implantation (CI) surgery. It determines the access to the auditory nerve and subsequent hearing performance. Here, we propose an objective measures tool that can partially verify the electrode position. The intracochlear spread of the electrical fields is measured and analyzed by means of multidimensional scaling resulting in an intuitive visual representation. The user can then detect major issues, such as electrode foldover or ossification. Other implantation issues, such as electrode migration into the scala vestibuli, may not significantly alter the electrical conduction pattern and remain undetected. Still, as the measurement is quick and readily available, it may be a valuable intraoperative verification tool.
Latent Dirichlet Co-Clustering (2006)

We present a generative model for simultaneously clustering documents and terms. Our model is a four-level hierarchical Bayesian model, in which each document is modeled as a random mixture of document topics , where each topic is a distribution over some segments of the text. Each of these segments in the document can be modeled as a mixture of word topics where each topic is a distribution over words. We present efficient approximate inference techniques based on Markov Chain Monte Carlo method and a moment-matching algorithm for empirical Bayes parameter estimation. We report results in document modeling, document and term clustering, comparing to other topic models, Clustering and Co-Clustering algorithms including latent Dirichlet allocation (LDA), model-based overlapping clustering (MOC), model-based overlapping co-clustering (MOCC) and information-theoretic co-clustering (ITCC).
[Features of respiratory diseases in ecologically unfavorable region]. (2001)

Examination of 400 workers in Bratsk aluminium plant proved respiratory diseases formation to be influenced by both occupational factors and various toxic chemicals that are released into atmosphere by other industrial polluters. Structure of respiratory diseases is represented mainly by diffuse pneumoconiosis caused by toxic and dust factors. Prophylaxis of those diseases should be aimed not only to better work conditions, but also to specify measures improving regional ecologic situation.
Simulation of Route Optimization with load balancing Using AntNet System (2013)

This paper is based on analysis of the performance of load balancing and route optimization in computerized networks. The complete system model shows the scenario of Packet distribution between nodes, and if congestion occurs due to traffic then Packet to be failed. The model used the AntNet system for simulate the network. The simulation runs on the ant's behavior for the load balancing of the network. The ants travel across the network between alternative chosen pairs of nodes; as they travel they deposit pheromones from their source node, collect the information of the route and the traffic congestion encountered on their journey. They select their path at each next node according the distribution of pheromones at each node. Packets between nodes are routed of the pheromone distributions at each next node. The performance of the network is proportional to packets which are failed. This model also shows the adaptivity of the system; the nodes are removed from the network, system finds the alternative chosen paths without system degradation and controls the performance of routing.

Bone Graft Substitutes in Sports Medicine (2007)

Bone graft substitutes are used commonly in orthopedic surgery as an alternative to autograft bone. Autograft bone has the advantages of being osteoconductive, osteoinductive, and osteogenic. However, the quantity of autograft bone available is limited in a given patient and the harvest of autograft bone has been associated with significant morbidity. Bone graft substitutes have become available in an attempt to address these issues and have found widespread use in many areas of orthopedic surgery including sports medicine. The various categories of bone graft substitutes are reviewed here, with an examination of their biologic mechanism of action. Clinical evidence to support their use is also reviewed, with a focus on sports medicine applications.
Pattern recognition, image processing, related data analysis and expert systems integrated in medical microscopy (2003)

The reasons why microscope imaging deserves attention are discussed. The major trends in medical end-user applications, are presented with particular emphasis on the integration of image processing and analysis, on-line statistical data analysis, and decision-making based on artificial intelligence at the highest level. It is emphasized that sophisticated image processing will not penetrate routine laboratory procedures until and unless the systems are oriented to the way the pathologists think and work. It is argued that assisting the human expert to improve his or her diagnostic reliability requires three basic components: powerful numerical image analysis; cognitive modules involving knowledge bases at both the image-analysis and decision-making levels; and man-to-computer interfacing compatible with the microscopists' behavior.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Advanced signaling protocol for broadband ISDN services (1995)

Abstract A signaling functional model (separated model) that assumes the functional separation of call control (CC) and bearer control (BC) must be considered for B‐ISDN because B‐ISDN deals with various levels of service quality, various speeds, and various connection configurations. This paper provides the basic structure of the forementioned separated model and the functions of the CC and BC based on actual B‐ISDN service specifications. Also, system design guidelines are proposed for connection‐type bandwidth selection and interworking between broadband ISDN and narrowband ISDN, which are key issues in the study of B‐ISDN signaling protocol.

Advanced control of PWM converter with variable-speed induction generator (2006)

This paper describes simple control structures for the vector-controlled stand-alone induction generator (IG) used to operate under variable speeds. Different control principles, indirect vector control and deadbeat current control, are developed for a voltage source pulsewidth-modulation (PWM) converter and the three-phase variable-speed squirrel-cage IG to regulate dc link and generator voltages with the newly designed phase-locked loop circuit. The required reactive power for the variable-speed IG is supplied by means of the PWM converter and a capacitor bank to buildup the voltage of the IG without the need for a battery, to reduce the rating of the PWM converter with the need for only three sensors, and to eliminate the harmonics generated by the PWM converter. These proposed schemes can be used efficiently for variable-speed wind energy conversion systems. The measurements of the IG systems at various speeds and loads are given and show that these systems are capable of good ac and dc voltage regulations
Visible laser sources based on frequency doubling in nonlinear waveguides (1997)

This paper reviews nonlinear quasi-phase-matching (QPM) waveguides and laser diodes with application to conversion of infrared laser diode wavelengths to the visible. The discussion of nonlinear QPM waveguides includes Ti-diffusion poled and E-field poled LiNbO/sub 3/ and KTP waveguides. Up to 25 mW of blue output power has been demonstrated for 120-mW infrared power injected into a nonlinear waveguide. Semiconductor laser sources suitable for frequency doubling are discussed, including distributed Bragg reflection (DBR) lasers operating at up to 200 mW output power, master oscillator power amplifiers with over 1 W output power, and wavelength-tunable flared semiconductor lasers with over 0.5 W output. A compact blue laser with 1-4 mW output power at 425-nm wavelength has been demonstrated based on a DBR laser frequency doubled in a nonlinear waveguide.

Supramolecular Thermo-Electrochemical Cells: Enhanced Thermoelectric Performance by Host–Guest Complexation and Salt-Induced Crystallization (2016)

Thermo-electrochemical cells have potential to generate thermoelectric voltage 1 order higher than that given by semiconductor materials. To overcome the current issues in thermoelectric energy conversion, it is of paramount importance to grow and fulfill the full potential of thermo-electrochemical cells. Here we report a rational supramolecular methodology that yielded the highest Seebeck coefficient of ca. 2.0 mV K(-1) around ambient temperatures. This is based on the encapsulation of triiodide ions in α-cyclodextrin, whose equilibrium is shifted to the complexation at lower temperatures, whereas it is inverted at elevated temperatures. This temperature-dependent host-guest interaction provides a concentration gradient of redox ion pairs between two electrodes, leading to the eminent performance of the thermo-electrochemical cells. The figure of merit for this system, zT reached a high value of 5 × 10(-3). The introduction of host-guest chemistry to thermoelectric cells thus provides a new perspective in thermoelectric energy conversion.
Synthesis and Pharmacological Comparison of Dimethylheptyl and Pentyl Analogs of Anandamide (1997)

(Dimethylheptyl)anandamide [(16,16-dimethyldocosa-cis-5,8,11,14-tetraenoyl)ethanolamine ] (17a) and its amide analogs were synthesized by Wittig coupling of a ylide derived from a fragment of arachidonic acid. These amides were compared to the endogenous cannabinoid receptor ligand arachidonylethanolamide (anandamide, 2a) and its amide analogs in pharmacological assays for potential enhancement of cannabimimetic activities. The receptor affinity to rat brain membranes of the dimethylheptyl (DMH) analogs increased by an order of magnitude in most comparisons to the corresponding anandamides in displacement assays versus the cannabinoid agonist [3H]CP 55,940 or antagonist [3H]SR141716A, for which rank order differences in affinity were observed. An order of magnitude enhancement of potency with comparable or higher efficacy in behavioral assays in the mouse tetrad of tests of cannabinoid activity was observed in 17a versus 2a. In contrast, no enhancement in potency for the pentyl to DMH side chain exchange was seen in the mouse vas deferens assay. The data indicate a structural equivalence between classical plant cannabinoids and 2a as well as different receptor-ligand interactions that characterize multiple receptor sites or binding modes.
