Transistor Device Optimization for RF Power Amplifier Employing Rapid Envelope Load-Pull System

This paper reports mathematical explanation and the application domain of rapid envelope load-pull system. It is demonstrated that this novel load-pull technique finds immediate use in the optimization of transistor devices for the design of microwave power amplifiers. The limitations of the existing load-pull systems severely affect the overall performance optimization of transistor devices. The envelope load-pull improves on the limitations of the existing systems and thus provides a very effective methodology for the design and investigation of the RF power amplifiers. Initially the paper describes the mathematical foundation of the envelope load- pull concept and then the rapid, accurate and reliable measurement capability of the system is presented. It clearly vindicates the potential areas of application of the system in improving the measurement throughput and yield optimization of the microwave devices. Finally, the harmonic envelope load-pull is utilized on a commercially available 1W GaAs FET that demonstrates the rapid RF power amplifier design, investigation and optimization strategy.
More concentration of Media ownership means less democracy? Testing association between variables

The literature in Political Science suggests that the access to alternative sources of information is essential in democracies. In theory, we expect that democratic countries have decentralized Media ownership. Therefore, we ask: is it possible to check – empirically – the existence of a negative correlation between concentrated Media ownership and democracy index? To answer this question, we used statistical methods, specially descriptive statistics and correlation test. The experiment confirmed the theoretical prediction: decentralized Media ownership is strongly associated with democratic countries.
Medical thermography: what is it? And its applications.

Thermography is a method still fresh in our medical practice. The author explained how is the modern medical thermography approach that is applied today as a means of a complementary radiologic diagnostic study. One of the basic indications and clinical uses of infrared (IR) imaging is documentation of soft tissue pathology, particularly in conditions which cannot be demonstrated on radiologic tests, electroneuromyography or laboratory workup.DOI: http://dx.doi. org/10.18073/2358-4696/pajmt.v2n1p14-17
A detailed electromagnetic investigation of the Franconian Lineament/Bavaria

Audiomagnetotelluric (AMT) measurements on four proles, combined with other near-surface geophysical investigations at the Franconian Line (FL) in the vicinity of the KTB reveal the complicated electrical structure of this fault zone, which marks the western border of the Bohemian Massif. The most prominent nding is a large conductivity anomaly associated with a 700 mV SP minimum in the southern proles crossing the SE1 reector found by KTB 3-D seismics. This suggests graphitized shear planes subparallel to this fault zone as its origin. The part of the FL striking approx. normal to the present direction of maximal compression shows much weaker, and only near-surface indications of the fault zone. These results may be explained by meteoric uids, possibly from the Mesozoic sediments in the SW present in the top 100 m of the fault.
Photoacoustic Measurements of Amplification of the Absorption Cross Section for Coated Soot Aerosols

A quantitative understanding of the absorption and scattering properties of mixed soot and aerosol particles is necessary for evaluating the Earth's energy balance. Uncertainty in the net radiative forcing of atmospheric aerosols is relatively large and may be limited by oversimplified models that fail to predict these properties for bare and externally mixed soot particles. In this laboratory study of flame-generated soot, we combine photoacoustic spectroscopy, particle counting techniques, and differential mobility analysis to obtain high-precision measurements of the size-dependent absorption cross section of uncoated and coated soot particles. We investigate how the coating of soot by nonabsorbing films of dibutyl phthalate (chosen as a surrogate for sulfuric acid) affects the particles’ morphology and optical properties. Absorption measurements were made with photoacoustic spectroscopy using a laser at λ = 405 nm. We report measurements and model calculations of the absolute cross section, mass absorption coefficient, and amplification of the absorption cross section. The results are interpreted and modeled in terms of a core–shell geometry and Lorenz–Mie theory of scattering and absorption. We discuss evidence of soot particle and collapse as a result of the coating process and we demonstrate the ability to resolve changes in the coating thickness as small as 2 nm.
Protocol for fish disease assessment in marine environmental monitoring using common sole (Solea solea, Linnaeus 1758) as sentinel organism: identification of externally visible diseases and liver histopathology

Monitoring the quantification of fish diseases is a well established and widely used tool to assess pollution effects in marine environments. However, there is sparse published information on externally visible diseases and on liver histopathology of common sole (Solea solea), a promising sentinel species in south-western Europe. To address this issue, we report a protocol in which, commonly recorded pathologies in common soles of the Basque coast (south-eastern Europe) are described. This protocol explains in detail the techniques used, from the sample collection to the methodological proposal for the evaluation of liver lesions through a single histopathologic index.
How does corporate social responsibility impact banking efficiency: a case in China

Much of the earlier literature was focused on the link between corporate social responsibility and corporate fi nancial performance, with contradictory conclusions regarding the impact of corporate social responsibility upon corporate fi nancial performance in the literature. Departing from conventional parametric techniques, this paper employs a fully nonparametric approach to analyze the link between corporate social responsibility and corporate fi nancial performance in Chinese banking sector. Specifi cally, the slack-free Multi-directional Effi ciency Analysis is extended into the conditional effi ciency framework. The results indicate that corporate social responsibility has a signifi cant impact on banking performance, where an increase in CSR generally leads towards an increase in conditional effi ciency, but the attainable frontier might be shifted to any direction for the highest values of corporate social responsibility. In details, the analysis of “pure” effi ciency indicates that corporate social responsibility has a stronger impact on increasing net profi t if compared to that on contracting the amount of non-performing loans. In other words, it turns out that corporate social responsibility is likely to affect the attainable frontier in the direction of expanding net profi t rather than contracting non-performing loans, because the portfolio of non-performing loans is diffi cult to reduce and therefore the impact of corporate social responsibility is not signifi cant either on the frontier or on average effi ciency. However, there exists a trade-off between corporate social responsibility and bank performance when a certain limit is exceeded in Chinese banking. Thus, a minimal increase in corporate social responsibility is likely to contribute to improvements in banking performance (productivity), whereas a negative effect is observed at the highest levels of corporate social responsibility.
Laser-induced effects on single layer graphene

In dieser Arbeit verwenden wir die Micro-Raman Spektroskopie und Raster-Kraft-Mikroskopie, um die Laser-induzierten Wirkungen von mechanisch expandiertem Einschicht-Graphen auf Si/SiO2-Substrate aufzuzeigen. Wir haben unsere Graphen-Proben fur ca. 10 Minuten unter Umgebungsbedingungen durch die Verwendung eines Nd:YAG-Festkorperlaserbeschrifters mit einer Wellenlange von 532 nm und einer maximalen Laserleistung von 32 mW bis 40 mW bestrahlt. Unsere Versuchsergebnisse zeigen eindeutig, dass als Folge der Aussetzung von Einschicht-Graphen auf Hochleistungsleiser mehrere Vorgange stattfinden. Einer dieser Vorgange ist die chemische Funktionalisierung der Graphen-Kristallgitter, die durch photo-induzierte chemische Reaktionen erzeugt wurden. Diese haben vermutlich die umgebenden Sauerstoff- und Wasserstoffmolekule eingeschlossen, die zwischen Si/SiO2-Substrat und Graphen gefangen waren. Zweitens, fuhrt die Dissoziation von Klebstoffruckstanden auf der Graphen-Oberflache, als Folge der Laser-induzierten Erwarmung, zur Entstehung von amorphem Kohlenstoff und zur Hydrierung von Graphen. Eine dritte Folge ist die strukturelle Anderung des Graphens, namlich von einer kristallinen Einschicht- zu einer nanokristallinen Struktur. Wir zeigen auch, dass die Reaktivitat des Graphens mit der Laserbehandlung lokal verstarkt werden kann. Wie die Experimente bestatigt haben, treten alle diese Effekte als Folge der Laserbestrahlung auf. Aufgrund der gleichzeitigen und moglicherweise gegenlaufigen Vorgange ist es schwer, erhebliche Auswirkungen jedes einzelnen Vorgangs zu erkennen und zu unterscheiden und die Veranderungen in dem Raman-Spektrum des Graphens zu interpretieren.
Gemstones from Vietnam: An Update

GEMS & GEMOLOGY FALL 2012 Vietnam, with an area of 335,000 km 2, occupies the eastern side of the Indochinese peninsula. Most of the country’s northern and central regions are mountainous, reaching an elevation of 3,142 m in the Fan Si Pan massif, near the Chinese border. The country is endowed with some 70 gem deposits and 160 different occurrences (Nguyen et al., 1995). Present gem production includes ruby, sapphire, spinel, tourmaline, peridot, garnet, aquamarine, topaz, quartz, and green orthoclase (e.g., figure 1). With more than 3,400 km of coastline, the country is also a source of saltwater cultured pearls, and several farms have emerged in recent decades. In addition, Melo pearls are retrieved by fishermen on the southern coast and in Ha Long Bay in the north. Compared with the country’s gem wealth, however, the Vietnamese mining industry remains undeveloped. Although it has been nearly 30 years since colored stones were discovered in Vietnam, mining and pearl farming activities are mostly smalland medium-scale operations run by private individuals or small companies. In March 1988, state-owned Vinagemco (Vietnamese Gems Company) was established to direct the exploration, mining, and trading of gem materials (Kane et al., 1991; Pham et al., 2004b). Two subsidiaries, Yen Bai Gemstone Company and Nghe An Gemstone Company, were set up in those provinces that same year. Ultimately, management problems led to the company’s downfall in July 2003. Since then, no state-owned company has been active in the gem sector. Mining, processing, cutting, and trading are all organized by private and joint-stock companies or private individuals. Scientific investigations of Vietnamese gem materials, including their properties and the genesis of the deposits, have resulted in several publications, with special attention to ruby and sapphire (e.g., Kane et al., 1991; Koivula and Kammerling, 1991; Kammerling et al., 1994; Smith et al., 1995; Pham et al., 2004a,b; Nguyen et al., 2011). This article updates the occurrence, production, and gemological features of Vietnam’s major gem materials, and outlines the geology of the deposits.

In-Situ Uranium Stabilization Through Polyphosphate Injection: Pilot-Scale Treatability Test at the 300 Area, Hanford Site - 8187

This paper describes the pilot-scale treatability test that was conducted to evaluate the efficacy of using a polyphosphate injection approach to treat uranium-contaminated groundwater in situ within the 300 Area aquifer at the Hanford Site in Richland, Washington. Primary test objectives were to assess 1) direct treatment of available uranium contributing to the groundwater plume through precipitation of the uranyl-phosphate mineral autunite, and 2) emplacement of secondary-treatment capacity via precipitation of the calcium-phosphate mineral apatite, which acts as a long-term sorbent for uranium. Based on an injection design analysis that incorporated results from both bench-scale testing and site-specific characterization activities, a three-phase injection approach was selected for field-scale testing. This approach consisted of 1) an initial polyphosphate injection to facilitate direct treatment of aqueous uranium in the pore space, 2) a second phase consisting of a calcium chloride injection to provide an available calcium source for the creation of apatite, and 3) a subsequent polyphosphate injection to supply a phosphate source for the formation of apatite. The total-solution volume injected during this field test was approximately 3.8 million L (1 million gal). Results from this investigation will be used to identify implementation challenges and investigate the technology's ability to meetmore » remedial objectives. In addition, data from this test will provide valuable information for designing a full-scale remedial action for uranium in groundwater beneath the 300 Area of the Hanford Site, and a detailed understanding of the fundamental underpinnings necessary to evaluate the efficacy and potential for utilization of the polyphosphate technology at other sites with varying geochemical and hydrodynamic conditions.

The reproductive ecology of elasipodid holothurians from the N.E. Atlantic

AbstractThe reproductive and population biology of the deep-sea elasipodid holothurian families Psychropotidae and Deimatidae from the North Atlantic is described. In the psychropotid species the ovary is a large thick-walled nodular structure containing oocytes with an interspecific maximum size of 1.2 mm to 3 mm. In the deimatid species the ovaries consist of thin-walled elongate tubules containing oocytes up to a maximum diameter of 900 μm. In the psychropotids all the oocytes undergo vitellogenesis whereas in the deimatids some could act as nurse cells for those oocytes continuing to grow. Fecundity is low in both families. The soluble lipid content of the ovary in all species is high when compared to other tissues. The calorific content of the whole ovary varies from 25.46 to 28.08 Jmg−1 AFDW. There is no evidence for any reproductive periodicity in any of the species examined.In the psychropotids the testes are well-developed structures packed with spermatozoa except in those specimens that are infe.
Introducing Complementary Foods to Infants in Central Mali

This study of the complementary feeding of infants age 3-12 months was undertaken to improve the understanding and interpretation of certain findings on the nutritional status of children in Mali from the Demographic and Health Survey (DHS) of 1995-1996. Most nutritionist agree that children need solid food in addition to breast milk when they are 4-6 months of age in order to reach their full growth potential. However the 1995-1996 survey in Mali found that only half of mothers reported giving solid foods to their children 6-9 months old that few children were exclusively breastfed and that most were given water or other liquids from birth. The study presented here seeks to understand how and when the process of initiating food supplementation occurs as mothers begin to give their infants either solid or mushy food in addition to breast milk. As such policy recommendations are provided at the end of this document.
Les virophages de Mimiviridae=The Mimiviridae virophages

Les virophages sont des petits virus a ADN possedant une capside icosaedrique de 50-60 nm et un genome de 17 a 26 Kb codant potentiellement pour une vingtaine de genes. Ils ont ete decouverts associes a des grands virus a ADN appartenant a l’ordre des Megavirales, pour lesquels leur presence serait deletere.Le premier projet du travail de these a ete de faire le bilan des proprietes connues des virophages au travers d’une revue. La deuxieme partie correspond a un bilan des avancees en matiere d’isolement de virus geants dans les amibes – hotes naturels des Mimiviridae –, pouvant etre associes aux virophages. La troisieme section se focalise sur la replication des virophages Sputnik avec differents virus parmi les Mimiviridae, ainsi que sur l’isolement d’une nouvelle souche de Sputnik sans son hote natif par l’utilisation d’un Mimiviridae en tant que virus rapporteur. La derniere partie est enfin basee sur l’identification d’un nouveau virophage – Zamilon – isole en association avec un Mimiviridae du groupe C, et presentant une specificite d'hotes restreinte. Celle-ci est d'ailleurs etudiee.Les resultats presentes dans cette these demontrent une certaine complexite des interactions entre les virophages et leurs hotes. Au sein d’une meme famille d’hotes, certains virophages possedent un large spectre de specificite, alors que d’autres ne peuvent se multiplier qu’avec certains d’entre eux, comme cela a deja ete observe chez les bacteriophages. Compte-tenu de leur impact potentiel sur les virus geants, ces resultats soutiennent l’hypothese d’une regulation des populations virales environnementales par les virophages.
Revealed preference and consumption behaviour at retirement

This paper sets out revealed preference tests for different models of consumption behaviour over retirement that we applied to a Spanish consumption panel dataset. We reject the perfect foresight model both with separable preferences and allowing for preference change. The first order conditions for the life-cycle model allowing for uncertainty do not provide very strong restrictions on possible choices. In fact they are no stronger than those implied by the most basic revealed preference requirement: GARP. We then go on to investigate the patterns of deviations from a perfectly smoothed marginal utility of wealth and ask whether they fit the predictions of the life-cycle model. We find a tendency of these to increase over time, suggesting consumption falls more than we'd expect. After considering various possible explanations, we settle on non-rational behaviour as the most plausible.
Research in Brief Communication and Health : An Interrogation

Health” is a highly prized positive value, a commodity and an industry—and also a topic of robust public and academic interest. This article aims to open a conversation about what a communications-oriented approach to health might look like. It reviews the Canadian Journal of Communication from its inception for instruction on how health-related topics have been examined by communication scholars, observing the lack of common questions and approaches when it comes to health and Canadian communication scholarship. The article suggests that alongside issues related to the ‘right to health’ and the ‘imperative of health’ (which is bound up with self-monitoring, lifestyle risks, and what I call the language of betterment), we might also important questions around promotion, packaging and embodiment.
Synchronization of Great Subduction Megathrust Earthquakes: Insights From Scale Model Analysis

The magnitude of great subduction megathrust earthquakes is controlled mainly by the number of adjacent asperities failing synchronously and the resulting rupture length. Here we investigate experimentally the long‐term recurrence behavior of a pair of asperities coupled by static stress transfer over hundreds of seismic cycles. We statistically analyze long (c. 500 ka) time series of M8‐9 analogue earthquakes simulated using a seismotectonic scale model approach with two aims: First, to constrain probabilistic measures (frequency‐size distribution, variability) useful for hazard assessment and, second, to relate them with geometric observables (coseismic slip pattern, locking pattern). We find that the number of synchronized asperity failures relative to the number of individual asperity failures as well as the coefficients of variation of recurrence intervals and seismic moment scale with the logarithm of stress coupling between the asperities. Accordingly, tighter packed asperities tend to recur more periodically and with a more characteristic magnitude while more distant asperities show clustering of more variable sized events. The probability of synchronized failures seems to be controlled to first order by geometrical relations (i.e., spacing and offset of asperities). The effects of rheological properties are evident but it remains to be explored to which extent they vary in nature and how sensitive the system is to those.
