SKMT: A Semantic Knowledge Management Tool for Content Tagging, Search and Management

With an ever increasing amount of content, we heavily rely on search engine to locate documents. Manual content Tagging can improve search results by allowing search engines to exploit tags generated by content authors. Manual tagging method introduces issues of bias and inconsistency from ad-hoc tagging, and increase burden to the authors. In this paper, we first introduce a semantic tagging engine that automatically generates semantic tags for the given documents. This tagging engine provides the ground for realizing semantic search, based on meanings of search terms and content tags. Then we present a Semantic Knowledge Management Tool (SKMT) as a semantic search and knowledge management platform to search, analyze and manage enterprise content. SKMT can scan different content sources and generate indexes of semantic keywords. Its user-friendly interface allows users to manage various data sources, search, explore and visualize search results at semantic level. Higher precision of semantic search and semantic data visualization are also demonstrated with examples as benefits of SKMT.
Bis(azido-κN)bis[6-(pyridin-2-yl)-1,3,5-triazine-2,4-diamine-κ2 N 1,N 6]manganese(II)

In the title complex, [Mn(N3)2(C8H8N6)2], the complete molecule is generated by the application of twofold symmetry, and is in a distorted octahedral environment, coordinated by four N atoms of two bidentate 6-(pyridin-2-yl)-1,3,5-triazine-2,4-diamine ligands and two N atoms from two azide anions. The two chelated 6-(pyridin-2-yl)-1,3,5-triazine-2,4-diamine ligands form a dihedral angle 74.75 (5)°. The mononuclear molecules are alternatively linked into layers parallel to the ac plane via N—H⋯N hydrogen bonds. Adjacent layers are connected into a three-dimensional supramolecular framework by futher N—H⋯N hydrogen-bonding interactions.
On the Performance of Spatially Correlated Large Antenna Arrays for Millimeter-Wave Frequencies

A spatially correlated large antenna array operating at millimeter-wave (mmWave) frequencies is considered. Based on a Saleh–Valenzuela channel model, closed-form expressions of the 3-D spatial correlation (SC) for wide, narrow, and Von Mises power elevation spectra (PESs) are analytically derived. The effects of the PES on the convergence to massive multiple-input-multiple-output properties are then illustrated by defining and deriving a diagonal dominance metric. Numerically, the effects of antenna element mutual coupling (MC) are shown on the effective SC, eigenvalue structure, and mmWave user rate for different antenna topologies. It is concluded that although MC can significantly reduce SC for side-by-side dipole antenna elements, the change in antenna effective gain (and, therefore, signal-to-noise ratio) caused by MC becomes a dominating effect and ultimately determines the antenna array performance. The user rate of an mmWave system with hybrid beamforming, using an orthogonal matching pursuit (OMP) algorithm, is then shown for different antenna topologies with dipole and cross-polarized (x-pol) antenna elements. It is seen that even for small numbers of radio frequency chains, the OMP algorithm works well relative to the fully digital case for channels with high SC, such as the x-pol antenna array.
Lipid Composition in Ganglia of Mollusca

Abstract: The aim of the present study is to ascertain lipid composition in the ganglia of Mollusca. Nervous ganglia in the periesophageal ring dissected from Helix pomatia, Lymnaea stagnalis, Murex trunculus and Murex brandaris were studied by biochemical and histochemical procedures. Glycosphyngolipids are present mainly as sulpholipid; sialic acid and gangliosides are not present as revealed by Svennerholm's reaction and TLC separation. The phospholipidcholesterol ratios are: 0.47 (Helix), 0.42 (Lyrnnaea), 0.86 (Murex brandaris) and 1.01 (Murex trunculus).
Serum heme‐albumin: An allosteric protein

Heme scavenging by plasma proteins, including serum albumin (SA), provides protection against free‐heme oxidative damage, limits access by pathogens to the heme, and contributes to iron homeostasis by recycling the heme iron. In turn, serum heme‐albumin (SA‐heme) acquires heme‐based ligand‐binding and (pseudo‐)enzymatic properties. Heme binding to SA and SA‐heme reactivity are allosterically and competitively modulated by endogenous and exogenous third components, this being relevant in pharmacotherapy management. © 2009 IUBMB IUBMB Life, 61: 1118–1122, 2009
Direct power control of reduced switch active filters

Nonlinear and time variant loads generate harmonic currents in power systems. Active filters (AF) are used to reduce the amplitude of these currents or omit them. Different control strategies have been presented for AF that among them the p-q theory is more popular. In this paper direct power control (DPC) method is used to implement the p-q theory. Active and reactive power of load and AF are measured and command values are calculated to compensate the load reactive power and just the oscillating part of load active power. The used converter is a reduced switch AF and has two switches less than a conventional full bridge AF, so this leads to less cost, complexity and loss. The simulation results show the excellent performance of this structure with zero source reactive power and a dc active power.
Inducing Changes in Breathing Patterns Using a Soft Robot

In this study, we examine whether touching a soft robot while doing different tasks can make participants synchronize their breathing rhythm with the robot. 28 participants interacted with the robot, which either was inflated and deflated, thus simulating breathing, or remained inactive. During the experiment, data were collected through two breathing belts and an EEG device. The findings of the study suggest higher arousal associated with positive emotional valence for participants in the breathing robot condition compared to the inactive robot condition. The participants in the breathing robot condition also breathed more deeply and regularly and blinked fewer times, a finding that suggests lower stress levels in comparison with people who interacted with the inactive robot. The analysis of the data suggests that touching the breathing robot led to some degrees of stress reduction, yet without leading to synchronization with the robot's inhalation rhythm.
Annual sediment primary production and respiration in a large coral reef lagoon (SW New Caledonia)

Sediment photosynthetic production and community respiration were investigated for 1 yr in the south-west lagoon of New Caledonia (surface area: 2000 km 2 ; mean depth: 21 m). Metabolic fluxes were measured at the water-sediment interface using benthic enclosures, at 60 sampling stations randomly distributed in space and time. Mean gross primary production (P g ) was 12.06 mol C m -2 yr -1 . Mean respiration (R) was 13.68 mol C m -2 yr -1 . P g /R was thus 0.88, indicating that the whole lagoon was net heterotrophic. There were, however, large differences along a land-ocean gradient. Muddy bottoms (35 % of the lagoon surface), located along the shore and in the deeper part of the lagoon, were significantly heterotrophic (Pg/R = 0.39), whereas the ratio for sandy bottoms (65 % of the area) towards the reef were close to 1 or slightly positive, indicating potentially autotrophic benthic communities. Both P g and R followed a similar seasonal variation with higher values during the warm season (November to February), when maximum irradiance and the particulate organic carbon supply occurred. These results suggest that autotrophy, generally observed in coral reef flats, may also occur in lagoon sediments, indicating both a major importance of regeneration processes and a relative equilibrium of energy exchanges with adjacent ecosystems. Terrestrial influence results in a decrease of autochthonous production and a correlative increase of carbon sedimentation leading to benthic heterotrophy.
Neuropeptides and their evolution

SUMMARY Neuropeptides are ubiquitous signalling molecules in all metazoans possessing nervous systems, from the simple nerve nets of the cnidarians to the immensely complex systems of mammals. While the discipline of peptide neuroendocrinology was born through the study of higher vertebrates, there now exists a plethora of information regarding neuropeptides and peptidic regulatory factors in invertebrates. Such phylogenetic studies have revealed that peptidic neurotransmission is of early evolutionary origin and that, while invertebrates have nervous systems which are simpler in terms of nerve cell number and organisation when compared with vertebrates, the complexity of the peptidic ‘vocabulary’ of invertebrate neurones is of a similar order of magnitude. Most research on invertebrate neuropeptides has been directed towards representative members of groups such as the insects and molluscs and it is only in recent years that efforts have been focused on the helminths (platyhelminths and nematodes). Here, the putative origins of peptidic transmitters is discussed and the current state of knowledge on helminth neuropeptides is reviewed. In order to place the study of helminth neuropeptides in an historical and conceptual perspective, methodological development and conceptual modifications in the disciplines of vertebrate and higher invertebrate peptide neuroendocrinology have been summarised.
Immunity to Asexual Erythrocytic Stages of Plasmodium Falciparum: Role of Defined Antigens in the Humoral Response 1

Malaria, a widespread disease of man and other vertebrates, is caused by a unicellular protozoan of the genus Plasmodium and is transmitted by the bite of female Anopheline mosquitoes. Among the four species which infect man, Plasmodium falciparum is by far the most lethal. The pathological consequences of malaria, characterized by febrile paroxysms, anemia, splenomegaly and debilitation, are due to the development and proliferation of asexual erythrocytic stages in the vertebrate host. A major public health problem in the world today, malaria presents a serious threat to economic and social development in large tropical and subtropical areas. More than one billion people live in endemic areas, over 200 million suffer from malaria and it is estimated that a million children under the age of 14 die annually from this disease in Africa alone (WHO 1976).
Probing the range of applicability of structure‐ and energy‐adjusted QM/MM link bonds

The hydrogen‐capping method is one of the most popular and widely used coupling‐schemes for quantum mechanics/molecular mechanics (QM/MM)‐molecular dynamics simulations of macromolecular systems. This is mostly due to the fact that it is fairly convenient to implement and parametrize, thus providing an excellent compromise between accuracy and computational effort. In this work, a viable and straight‐forward approach to optimize the placing of the link atom on a suitable distance ratio between the frontier atoms is discussed. To further increase the accuracy, instead of global parameters for all amino acids, different parameter sets for each type of amino acid are derived. The dependency of the link bond parameters on the chemical environment and the used QM‐method is probed to assess the range of applicability of the parametrization. Suitable sets of parameters for RI‐MP2, B3LYP, (RI)‐B3LYP‐D3, and RI‐BLYP‐D3 at triple‐zeta level for all relevant proteinogenic amino acids are presented. Furthermore, the scope and range of the perturbation, stemming from the introduction of link bonds is evaluated through application of the presented QM/MM scheme in calculations of the active site of 15S‐lipoxygenase. © 2015 Wiley Periodicals, Inc.
Multi-Agent Optimal Allocation of Energy Storage Systems in Distribution Systems

A variety of optimal methods for the allocation of a battery energy storage system (BESS) have been proposed for a distribution company (DISCO) to mitigate the transaction risk in a power market. All the distributed devices are assumed to be owned by the DISCO. However, in future power systems, more parties in a distribution system will have incentives to integrate BESS to reduce operational cost. In this paper, an enhanced BESS optimal allocation method is proposed for multiple agents in a distribution system. First, the electricity market mechanism is extended to a distribution system, and the corresponding energy transaction process is modeled for different agents, such as wind farms, solar power stations, demand aggregators, and the DISCO. The uncertainties of renewable energy and demand are addressed using stochastic methods. In the proposed transaction model, the integration of BESS can help an agent to reduce the operational cost, also defined as the payoff function. Next, game theory is introduced in this paper to investigate the interactions among the agents and to determine the BESS integration plans. The agents are built as players who are willing to minimize their payoff functions in the proposed non-cooperative game. The Nash equilibrium, which is the best strategy for the players, is proved to exist. Such equilibrium can be solved using an iterative algorithm. The proposed BESS allocation method for the multi-agent system is verified for two cases, and the payoff reductions are quantified based on the proposed distribution energy transaction mechanism.
Targeting TLR3 with no RIG-I/MDA5 activation is effective in immunotherapy for cancer

Introduction: Many forms of RNA duplexes with agonistic activity for pattern-recognition receptors have been reported, some of which are candidates for adjuvant immunotherapy for cancer. These RNA duplexes induce cytokines, interferons (IFNs) and cellular effectors mainly via two distinct pathways, TLR3/TICAM-1 and MDA5/MAVS. Areas covered: We determined which pathway of innate immunity predominantly participates in evoking tumor immunity in response to RNA adjuvants. Expert opinion: In knockout (KO) mouse studies, robust cytokine or IFN production is dependent on systemic activation of the MAVS pathway, whereas maturation of dendritic cells (DCs) to drive cellular effectors (i.e., NK and CTL) depends on the TICAM-1 pathway in DCs. MAVS activation often causes endotoxin-like cytokinemia, while the TICAM-1 activation does not. Unlike the TLR/MyD88 pathway, this TICAM-1 pathway barely accelerates tumor progression. Although the therapeutic effect in human patients of MAVS-activating or TICAM-1-activating RNA duplexes remains undetermined, the design of a TLR3 agonist with optimized toxicity and dose is an important goal for human immunotherapy. Here we summarize current knowledge on available RNA duplex formulations, and offer a possible approach to developing a promising RNA duplex for clinical tests.
Modeling and quantitative analysis of actin cytoskeleton networks

In eukaryotischen Zellen bildet das Strukturprotein Aktin Polymernetzwerke aus, die sehr dynamisch und fur viele zellulare Prozesse lebenswichtig sind. In dieser Arbeit werden theoretische Konzepte vorgestellt, um die Eigenschaften komplexer Aktin-Netzwerkstrukturen zu verstehen und mit Messungen mittels Fluoreszenz- und Elektronenmikroskopie zu vergleichen. Ein Grosteil der Arbeit behandelt dabei flache vernetzte Aktinstrukturen, die durch gerichtete Polymerisation gegen eine ausere Kraft anwachsen. Dieser Netzwerktyp ist ein wichtiger Bestandteil von sich bewegenden Zellen, wird aber auch von intrazellularen Pathogenen zur Fortbewegung missbraucht. Eine zentrale, experimentell messbare Eigenschaft solcher Netzwerke ist ihre Kraft-Geschwindigkeits-Relation. Verschiedene aktuelle Messungen ergaben hierfur widerspruchlich erscheinende Ergebnisse. In einem relativ einfachen physikalischen Modell wird gezeigt, dass in wachsenden Aktin-Netzwerken zwei stationare Filament-Orientierungsverteilungen miteinander konkurrieren. Strukturelle Ubergange zwischen den beiden Architekturen werden durch Anderung der Wachstumsgeschwindigkeit des Netzwerks initiiert. Mit zusatzlichen Annahmen zur mechanischen Stabilitat einzelner Filamente werden die experimentell gefundenen Eigenarten der Kraft-Geschwindigkeits-Relation (eine Abfolge von konvexen und konkaven Verlaufen sowie Hysterese) theoretisch begrundet. Das Modell wird zusatzlich auf Aktinwachstum gegen gekrummte Hindernisse wie intrazellulare Pathogene erweitert. Um in der Zukunft spezifische Vorhersagen des Modells experimentell zu uberprufen, wurde eine Methode zur automatischen Analyse von Elektronenmikroskopiebildern von Aktin-Netzwerken entwickelt. Erste Ergebnisse lassen eine gute Ubereinstimmung erwarten. Des Weiteren wurde eine Methode entwickelt, um Anderungen in der Aktin-Struktur von adharenten Zellen in einem Hochdurchsatzverfahren mit Fluoreszenzmikroskopie zu bewerten.
An Investigation of DC and RF Safe Operating Area of n-p-n  $+$ p-n-p SiGe HBTs on SOI

We have examined the reliability risks of complementary SiGe HBTs on thick-film silicon on insulator (SOI). DC stress techniques, such as reverse emitter-base (EB) stress, mixed-mode stress, and flyback measurements, were used to characterize the safe operating area of n-p-n and p-n-p SiGe HBTs fabricated on SOI substrates. The measurements were analyzed based on fundamental damage mechanisms, such as hot carriers generated at the EB and collector-base junctions during large reverse voltage, and thermal runaway as a result of high current phenomena. RF stress (using a large amplitude continuous-wave signal) was also performed to examine the reliability of complementary bipolar complementary metal-oxide-semiconductor devices and circuits in an RF context. In both cases, p-n-p SiGe HBTs were found to be more reliable than n-p-n SiGe HBTs, a fact that may offer opportunities for circuit design optimization.
Suitability of recycled HDPE for 3D printing filament

3D printing technology has been popular lately and the most used filament is ABS and PLA. There is a concern about how the filament should be made of recycled material, therefore this research was aimed to find recycled HDPE specification and extrusion parameters for 3D filament. Comparisons were made between ABS, PLA and recycled HDPE in order to obtain these parameters. The mechanical properties of recycled HDPE such as melt flow, tensile strength, young modulus and yield strain was observed to go along the PLA parameters used as 3D filament. The result shows that recycled HDPE has the potential properties as 3D filament with essential puling speed and specific cooling method employed.

An analysis of loss-free data aggregation for high data reliability in wireless sensor networks

Data aggregation is am important feature in Wireless Sensor Networks, used primarily to reduce energy use. This paper extends our previous results, which showed that data aggregation can improve the reliability of data delivery rather than degrading it as previously assumed. These previous results were based on the use of scaleable aggregation functions, such as SUM, COUNT, MIN, MAX which work independently of the network size. In this paper we extend these results to consider the reliability and energy efficiency of lossless data delivery with the semi-scaleable aggregation function APPEND, and determine the boundary conditions under which the data reliability can be maintained without an increase in the energy cost. These new results show that lossless aggregation using the APPEND aggregation function can provide improved reliability with reduced energy usage in certain conditions.
Specific absorption rate evaluation for people using wireless communication device in vehicle

In this paper, a specific absorption rate (SAR) evaluation on human exposure from wireless communication devices inside a vehicle is investigated. A finite-difference time-domain method (FDTD) is used for simulating the electromagnetic field distribution inside the vehicle. Results have shown that the maximum SAR induced for a mobile phone user in the vehicle is only increased by 5% when compared to free space. Results have also indicated that other passengers in the vehicle are also inducing various levels of the SAR values in their bodies. The induced SAR values can be as high as about 40% of the maximum SAR value induced in the mobile phone user.
Meat and colo-rectal cancer

In early epidemiological studies of diet and cancer the stress was on the search for causal factors. Population (ecological) studies tended to show a strong correlation between meat intake, particularly red meat, and the risk of colo-rectal cancer. They also tended to show meat to be strongly inversely correlated with cancers of the stomach and oesophagus and liver. Early case- control studies tended to support the postulated role for red meat in colo-rectal carcinogenesis, although more recent case-control studies, particularly those from Europe, have tended to show no relationship. The cohort studies in general failed to detect any relationship between meat intake and colo-rectal cancer risk. The available evidence points to the intake of protective factors such as vegetables and whole-grain cereals being the main determinants of colo-rectal cancer risk, with meat intake only coincidentally related.
Genetic Variation and Population Structure of the Sable Martes zibellina on Eastern Hokkaido, Japan, Revealed by Microsatellite Analysis

Abstract. To assess the genetic variation and population structure of the sable Martes zibellina on eastern Hokkaido, Japan, we analyzed genotypes of 12 microsatellite loci on 48 individuals. Genotypes for all individuals examined were found to be different from each other. Mean observed and expected heterozygosites and allelic richness were calculated to be 0.52 (0.02–0.80), 0.58 (0.02– 0.79) and 5.49, respectively. The genetic diversity of the eastern Hokkaido population was similar to those of farm-bred sables in Russia and other mustelids. STRUCTURE analysis showed that the sables of eastern Hokkaido were grouped into two genetic clusters. Eighty-nine percent (24/27) of individuals assigned to cluster 1 were distributed around Shiretoko Peninsula, whereas 81% (17/21) assigned to cluster 2 were distributed in the inner side of Hokkaido (Tokachi District). The two subpopulations could have been genetically differentiated due to geographic barriers such as higher mountains, lakes, rivers and solfatara areas, although the geographic isolation did not seem to be complete.
Social-aware cooperation among mobile terminals for wireless downlink transmission

This paper investigates the social-aware cooperation (SAC) among mobile terminals (MTs), motivated by the fact that modern smart devices have much improved context awareness. Aware of the social ties, the cooperative network contains two layers of property: social and physical. In order to observe how the social awareness benefit the cooperation performance, we first formulate the social ties between MTs into parameters that can describe the cooperative behaviors by taking the mobility feature into account, defined as the conviction-approval-suspicion (CAS) model. Limited by the processing capability, partner selection is of great practical significance. To this end, the social-aware partner selection strategy is analyzed, and a significant superiority is observed compared to social-unaware selection. By analyzing the cooperative throughput, an explicit relationship between the degrees-of-freedom gain and the social-physical property is finally derived. Simulation results validate the theoretical analysis.
