description: No abstracts are to be cited without prior reference to the author.Comprehensive assessments of marine ecosystems incorporating abiotic and biotic components, natural and anthropogenic disturbances, including fishery harvests, are being pursued with increasing frequency. Mapping benthic habitats on appropriate spatial scales is an essential first step, providing a backdrop for assessing fisheries as well as the impacts of environmental change. Presently, the habitats of the Northeastern USA continental shelf are poorly understood. Substrate distribution information relies heavily on geological sampling (e.g. grabs and cores), while megabenthos information is typically derived from by-catch in fisheries surveys. These historical datasets are spatially and temporally inconsistent. Sidescan, and more recently, multibeam sonar methods provide improved sediment and sea floor morphology information but presently little of the continental shelf has been mapped. Further, these methods do not directly sample megabenthos. Beginning in 1999, we conducted a visual census of surficial substrates and megabenthos in offshore sea scallop, Placopecten magellanicus, beds using underwater video in a centric, systematic, quadrat survey design. We have examined 172,848 quadrats, viewing >250,000 m2 of sea floor along 60,000 km2 of continental shelf. These data were used to map surficial substrates and megabenthos, assess the impacts of a short term sea scallop fishery, produce an identification key for megabenthos and substrates, and provide fishery managers spatially explicit sea scallop density and size distribution information.

description: Poster presented at EURASIA 2018 (Rome) The synthesis of colloidal photo-luminescent semiconductor quantum dots (QDs), belonging to II-VI groups, even from single source precursors is presented. Since three decades their synthesis has been pursued implementing new and easier synthetic conditions that standardize their production. In this work is reported the production of luminescent of CdS QDs in a polymeric film induced by laser processing. A film of PMMA doped with two types of precursors of cadmium carboxylate and tellurium phosphinate is deposited as a thin film to observe the formation of CdTe QDs. The CdTe formation is observed after thermal annealing for different time by means of UV-Vis and photoluminescence spectroscopy. The optical analysis showed the formation of CdTe QDs with size between 3 – 4 nm and with an emission photoluminescence included in the 540 650 nm region. These results pave the way for patterning of QDs by inducing thermal annealing in selected areas of the film.

description: Transition metal dichalcogenide monolayers are highly interesting for potential valleytronic applications due to the coupling of spin and valley degrees of freedom and valley-selective excitonic transitions. However, ultrafast recombination of excitons in these materials poses a natural limit for applications, so that a transfer of polarization to resident carriers is highly advantageous. Here, we study the low-temperature spin-valley dynamics in nominally undoped and n-doped MoSe$_2$ monolayers using time-resolved Kerr rotation. In the n-doped MoSe$_2$, we find a long-lived component of the Kerr signal which we attribute to the spin polarization of resident carriers. This component is absent in the nominally undoped MoSe$_2$. The long-lived spin polarization is stable under applied in-plane magnetic fields. Spatially resolved measurements allow us to determine an upper boundary for the electron spin diffusion constant in MoSe$_2$.

description: This article analyses Jacques Brel’s influence on Giorgio Gaber’s LP I borghesi, published in 1971. After defining Gaber’s role in the early cantautori movement and his stance in the political debate of the late sixties and seventies, this paper mainly focuses on the songs adapted from Brel’s “Ces gens-là”, “Les bourgeois” and “Jef”. The fact that neither Gaber nor his co-author Sandro Luporini spoke French fluently allows us to investigate the fact that (and the ways in which) the adaptation of a song can draw inspiration from music and interpretation rather than the mere translation of the lyrics.

description: Electrical motors are vital components of many industrial processes and their operation failure leads losing in the production line. Motor functionality and its behavior should be monitored to avoid production failure catastrophe. Hence, a high‐tech DSP processor is a significant method for electrical harmonic analysis that can be realized as embedded systems. This chapter introduces the principal embedded design of novel high‐tech 1024‐point FFT processor architecture for high-performance harmonic measurement techniques.In FFT processor algorithm pipelining and parallel implementation is incorporated in order to enhance the performance. The proposed FFT makes use of floating point to realize higher precision FFT. Since floating‐point architecture limits the maximum clockfrequency and increases the power consumption, the chapter focuses on improving the speed, area, resolution and power consumption, as well as latency for the FFT. It illustrates very large‐scale integration (VLSI) implementation of the floating‐point parallelpipelined (FPP) 1024‐point Radix II FFT processor with applying novel architecture that makes use of only single butterfly incorporation of intelligent controller. The functionality the conventional Radix II FFT was verified as embedded in FPGA prototyping. For area and power consumption, the proposed Radix II FPP‐FFT was optimized in ASIC under Silterra 0.18 μm and Mimos 0.35 μm technology libraries.

description: We study the two-dimensional electron gas in a magnetic field at filling fraction $ν=\frac{1}{2}$. At this filling the system is in a gapless state which can be interpreted as a Fermi liquid of composite fermions. We construct trial wave functions for the system on a torus, based on this idea, and numerically compare these to exact wave functions for small systems found by exact diagonalization. We find that the trial wave functions give an excellent description of the ground state of the system, as well as its charged excitations, in all momentum sectors. We analyze the dispersion of the composite fermions and the Berry phase associated with dragging a single fermion around the Fermi surface and comment on the implications of our results for the current debate on whether composite fermions are Dirac fermions.

Reale und fiktive Sender-Adressaten-Konstellationen in Fußball-Fangesängen – mit romanistischen Beispielen

description: Football chants have been researched in several disciplines – from musicology to ethnology to linguistics – for quite a while now. They have been most intensively investigated in the German speaking countries, thus focusing on German chants; Kopiez/Brink 1998 is still the reference work in this respect. Other languages and cultures, however, have been studied much less; this paper therefore proposes an investigation of the (lyrics of) football chants of Romance language cultures using a corpus of French, Spanish and Italian songs. The analysis follows a new categorizing scheme, namely “participant constellations”, i.e. constellations of senders and addressees (fans towards their own team, fans towards referees, fans towards opponents’ fans etc.). The results reveal that constellations can be both real and fictitious; in the latter case, the fans sing a text which takes the position of a first person and is sung from the perspective of one exemplary fan. This is the case in chants which stylize the fan’s connection with his/her team as a romantic relationship. The corpus also contains other, sometimes very original fictitious speakers that are linked to the feeling of togetherness among the fan base and show creativity and humour.

description: The grain boundaries (GBs) of a graphene surface were extensively studied because GBs with specific defect configurations result in the formation of new curved structures, which can be treated as new carbon allotropes. We studied the structures and electronic spectra of two periodic GBs in graphene on highly oriented pyrolytic graphite (HOPG) surfaces using scanning tunneling microscopy and spectroscopy (STM/S). Our results demonstrated that a GB consisting of dual parallel periodic dislocation cores of pentagonal-heptagonal (5-7) carbon rings gives rise to an enhanced localized state at 0.45 eV above the Dirac point in graphene surfaces, which is attributed to van Hove singularities (VHSs). Moreover, the energy positions of the localized states are varied between 0.40 and 0.47 eV depending on the site and eventually decayed to 0.36 eV. The variation of the energy positions is induced by two parallel GBs because of the higher electron density at the GB as a defect center and the lower electron away from the GB. Another periodic GB with a symmetric zigzag structural feature induced VHSs at -0.038 and 0.12 eV near the Fermi level. Moreover, intervalley scattering was observed on both these GBs. This means that carrier concentration and thus, the conductance around the periodic GBs can be significantly enhanced by localized density of states. This finding suggests that graphene with a properly embedded ordered GB is promising for improving the performance of graphene-based electronic devices.

description: We describe two efficient on-line algorithms to simplify weighted graphs by eliminating degree-two vertices. Our algorithms are on-line in that they react to updates on the data, keeping the simplification up-to-date. The supported updates are insertions of vertices and edges; hence, our algorithms are partially dynamic. We provide both analytical and empirical evaluations of the efficiency of our approaches. Specifically, we prove an O(log n) upper bound on the amortized time complexity of our maintenance algorithms, with n the number of insertions.

description: Electrical motors are vital components of many industrial processes and their operation failure can lead to loss in production. Motors are found in many applications in industrial apparatus. Conditioned monitoring of the motor enables early detection of abnormalities; for proactive response maintenance procedures to avoid catastrophe. The diagnosis of motor faults improves the efficiency of industrial plants. Meanwhile the precise analysis and accurate measurement of harmonic provides a reliable scientific industrial application. Hence, the high performance DSP processor is the important method of electrical harmonic analysis. However, it can be realized in embedded systems. In this book, the effort was taken to implement a novel high-resolution single chip 1024-point FFT processor architecture for improvement of the harmonic measurement techniques. This book starts with design then followed by the simulation and its hardware implementation to demonstrate the benefit that is achieved by the proposed 1024-point FFT processor.

description: Strong gravitational lensing provides an independent measurement of the Hubble parameter ($H_0$). One remaining systematic is a bias from the additional mass due to a galaxy group at the lens redshift or along the sightline. We quantify this bias for more than 20 strong lenses that have well-sampled sightline mass distributions, focusing on the convergence $κ$ and shear $γ$. In 23% of these fields, a lens group contributes a $\ge$1% convergence bias; in 57%, there is a similarly significant line-of-sight group. For the nine time delay lens systems, $H_0$ is overestimated by 11$^{+3}_{-2}$% on average when groups are ignored. In 67% of fields with total $κ\ge$ 0.01, line-of-sight groups contribute $\gtrsim 2\times$ more convergence than do lens groups, indicating that the lens group is not the only important mass. Lens environment affects the ratio of four (quad) to two (double) image systems; all seven quads have lens groups while only three of 10 doubles do, and the highest convergences due to lens groups are in quads. We calibrate the $γ$-$κ$ relation: $\log(κ_{\rm{tot}}) = (1.94 \pm 0.34) \log(γ_{\rm{tot}}) + (1.31 \pm 0.49)$ with a rms scatter of 0.34 dex. Shear, which, unlike convergence, can be measured directly from lensed images, can be a poor predictor of $κ$; for 19% of our fields, $κ$ is $\gtrsim 2γ$. Thus, accurate cosmology using strong gravitational lenses requires precise measurement and correction for all significant structures in each lens field.

description: We report on Australia Telescope Compact Array observations in the direction of the young high magnetic-field pulsar J1119-6127. In the resulting images we identify a non-thermal radio shell of diameter 15', which we classify as a previously uncatalogued young supernova remnant, G292.2-0.5. This supernova remnant is positionally coincident with PSR J1119-6127, and we conclude that the two objects are physically associated. No radio emission is detected from any pulsar wind nebula (PWN) associated with the pulsar; our observed upper limits are consistent with the expectation that high magnetic-field pulsars produce radio nebulae which fade rapidly. This system suggests a possible explanation for the lack of an associated radio pulsar and/or PWN in many supernova remnants.

description: The Cascaded Integrator Comb filters (CIC) find many applications in recent electronic devices such as frequency selection functions in a digital radio or modem and any filter structure that is required to efficiently process large sample rate factor. These filters are normally located after the sigma-delta modulator and have a regular structure. These types of filters do not require multipliers and the coefficient storage unlike in the normal digital FIR and IIR filters because of all filter coefficients are unity. Hence, it can be efficiently implemented to operate at high speed. Hence, this book describes the Very Large Scale Integration (VLSI) implementation of the CIC filters that are suitable for high-performance audio applications.

description: Jérôme Minière’s song “La vérité est une espèce menacée”, first released online on January 11, 2018, strikes the listener by its profound interdependence of text, music, and interpretation. Text, music, voice, programming, instruments, editing, mixing, and clip making bear the same name, Jérôme Minière, who has rightly been acclaimed as one of today’s particularly promising multitalents. Compared to the parameters of popular music, the song is atypical in that it is not sung but recited. Its floating tonality corresponds with the fragile construction of the text while the video clip underlines the impression of fragmentation and flow perfectly in tune with the rhythm of the music and the spoken word. Altogether the song evokes an existential journey from metaphysical and societal crisis to arrival at a moment of potential becoming, an ‘end times’ spirituality, relative and ambivalent.

description: High temporal stability and spin dynamics of individual nitrogen-vacancy (NV) centers in diamond crystals make them one of the most promising quantum emitters operating at room temperature. We demonstrate a chip-integrated cavity-coupled emission into propagating surface plasmon polariton (SPP) modes narrowing NV center's broad emission bandwidth with enhanced coupling efficiency. The cavity resonator consists of two distributed Bragg mirrors that are built at opposite sides of the coupled NV emitter and are integrated with a dielectric-loaded SPP waveguide (DLSPPW), using electron-beam lithography of hydrogen silsesquioxane resist deposited on silver-coated silicon substrates. A quality factor of ~ 70 for the cavity (full width at half maximum ~ 10 nm) with full tunability of the resonance wavelength is demonstrated. An up to 42-fold decay rate enhancement of the spontaneous emission at the cavity resonance is achieved, indicating high DLSPPW mode confinement.

description: To improve the linearity of the transconductor in digital TV tuner application, a new technique of multiple gated transistors in self-biasing basis is presented. The proposed design decreases the bill-of-material (BOM) and offers less complexity of the structure. In addition, the proposed transconductor with utilizing by third-order Chebyshev introduces low-pass filter with low power consumption and the cutoff frequency of 50-200 MHz. The hybrid tracking low-pass filter is designed to overcome the issue of local oscillator harmonic-mixing for Advanced Television System Committee terrestrial digital TV tuner integrated circuit. The proposed operational transconductor amplifier (OTA) is designed and implemented in 90 nm CMOS technology. The simulation result with the two-tone test at 100 MHz center frequency proves the proposed OTA has 5 dBm Input-referred Third-Order Intercept Point (IIP3) in compare witha single-gate OTA in the third-order Chebyshev filter. The proposed OTA achieves maximum noise figure (NF) of 13 dB and maximum IIP3 of approximately 21.7 dBm at 100 MHz, whereas consuming 18 mA with 1.2 V supply voltage and it shows great improvement.

description: Temporal networks are increasingly being used to model the interactions of complex systems. Most studies require the temporal aggregation of edges (or events) into discrete time steps to perform analysis. In this article we describe a static, lossless, and unique representation of a temporal network, the temporal event graph (TEG). The TEG describes the temporal network in terms of both the inter-event time and two-event temporal motif distributions. By considering these distributions in unison we provide a new method to characterise the behaviour of individuals and collectives in temporal networks as well as providing a natural decomposition of the network. We illustrate the utility of the TEG by providing examples on both synthetic and real temporal networks.

description: Recent criminal court reforms have required prosecutors to provide defense attorneys with broader and earlier discovery of evidence. For these discovery reforms to fulfill their aims of improved fairness and efficiency, defense attorneys must take advantage of the evidence disclosed by the prosecution. Prior studies suggest, however, that a range of factors, including low pay and high caseloads, impede effective defense representation in general. If similar factors hinder defense attorneys from reviewing discovery, discovery reforms would fail to meet their goals, and defendants would receive sub-standard representation. The recent adoption of digital evidence platforms by local jurisdictions allows us to study whether defense attorneys consistently fulfill their duty to review discovery. Analyzing data from digital evidence platforms used in felony cases in four Texas counties between 2018 and 2020, we examine whether and when defense attorneys fail to access evidence disclosed by the prosecution. We find that a substantial number of defense attorneys never access the discovery. The access rate varies by county, offense seriousness, attorney category, attorney experience, and file type. Drawing on review of prior scholarship and Bayesian analysis of the data, we discuss plausible interpretations of these variations.

description: A laser cooling method for trapped atoms is described which achieves ground state cooling by exploiting quantum interference in a driven Lambda-shaped arrangement of atomic levels. The scheme is technically simpler than existing methods of sideband cooling, yet it can be significantly more efficient, in particular when several motional modes are involved, and it does not impose restrictions on the transition linewidth. We study the full quantum mechanical model of the cooling process for one motional degree of freedom and show that a rate equation provides a good approximation.

Fare l’americano, dagli anni Cinquanta a oggi: riflessioni sulle cover versions della hit carosoniana

Publisher: name: ATeM Archiv für Textmusikforschung
Year: 2020

description: Since its first release in 1956, Renato Carosone’s Neapolitan swing “Tu vuò fa’ l’americano” has been covered extensively. The interest in this piece increased significantly after 1999, thanks to its use in the movie The Talented Mr. Ripley and a number of ‘interlinguistic’ covers.
This study aims at identifying the main elements, both in the lyrics and in the music of the original song, that generated this flow of alternative versions, as an attempt to discern the “patchwork of references” that has become a fundamental feature of popular music (Holm-Hudson 2002). It argues that the ironic use of national and cultural stereotypes is at the core of the process of covering “Tu vuò fa’ l’americano”, together with the fundamentally intercultural sonic and textual representation of a Neapolitan-wannabe-American. Simultaneously, the musical structure has been adopted by the covers as a sort of elastic structure from which each musician and composer can extract bits that are relevant to their artistic discourse while still retaining a recognizable relationship to the original.
The article is introduced by an overview of the theoretical discussion around the process of covering that gravitates around – although not restricted to – taxonomies of covers in popular music. The central part focuses on musical and textual components that inspired artists to create different versions of “Tu vuò fa’ l’americano”. It then provides an interpretation of a substantial, albeit not exhaustive, corpus of different covers of Carosone’s hit, dividing them into typologies that aim not only at pointing out the semiotic processes involved, but also at casting light on the reasons why this song has been covered within such a vast array of linguistic and stylistic contexts.

description: We present the observation of the Tycho supernova remnant obtained with the EPIC and RGS instruments onboard the XMM-Newton satellite. We compare images and azimuthally averaged radial profiles in emission lines from different elements (silicon and iron) and different transition lines of iron (Fe L and Fe K). While the Fe XVII L line and Si XIII K line images are globally spatially coincident, the Fe K emission clearly peaks at a smaller radius, indicating a higher temperature toward the reverse shock. This is qualitatively the profile expected when the reverse shock, after travelling through the outer power-law density profile, has entered the central plateau of the ejecta. The high energy continuum map has an overall smooth distribution, with a similar extent to the radio emission. Its radial profile peaks further out than the lines emission. Brighter and harder continuum regions are observed with a rough bipolar symmetry in the eastern and western edges. The spectral analysis of the southeastern knots supports spatial variations of the relative abundance of silicon and iron, which implies an incomplete mixing of the silicon and iron layers.

description: No abstracts are to be cited without prior reference to the author.The macrobenthos of the deep, northern Gulf of Mexico has been sampled with large box cores along multiple cross-depth transects extending from depths of 200 m out to 3700 m. Four major depth zones (β diversity) have been identified based on the faunal similarities between geographic sites, with the two intermediate-depth zones being divided horizontally down the middle of the basin. The input of food resources appears to control the observed patterns. Each zone and sub-zone can be described by a characteristic animal density, biomass and biodiversity (α diversity). Highest densities and biomass occurred in two large submarine canyons, but the two habitats are markedly different. The α diversity displays an intermediate depth maximum in some groups, but not in others. Species richness (γ diversity) is highest in the Mississippi Canyon, due, we suggest, to habitat complexity, but α diversity is lowest at the canyon head due to extreme dominance by a soon-to-be-described ampeliscid amphipod. Small mean individual size and low densities encountered are a reflection of the meager surface water primary production, albeit with exceptional isolated habitats in which detrital material is concentrated, such as canyons on the upper continental slope.

description: The last decade was remarkable for neutrino physics. In particular, the phenomenon of neutrino flavor oscillations has been firmly established by a series of independent measurements. All parameters of the neutrino mixing are now known and we have elements to plan a judicious exploration of new scenarios that are opened by these recent advances. With precise measurements, we can test the 3-neutrino paradigm, neutrino mass hierarchy and CP asymmetry in the lepton sector. The future long-baseline experiments are considered to be a fundamental tool to deepen our knowledge of electroweak interactions. The Deep Underground Neutrino Experiment -- DUNE will detect a broad-band neutrino beam from Fermilab in an underground massive Liquid Argon Time-Projection Chamber at an L/E of about $10^3$ km / GeV to reach good sensitivity for CP-phase measurements and the determination of the mass hierarchy. The dimensions and the depth of the Far Detector also create an excellent opportunity to look for rare signals like proton decay to study violation of baryonic number, as well as supernova neutrino bursts, broadening the scope of the experiment to astrophysics and associated impacts in cosmology. In this presentation, we will discuss the physics motivations and the main experimental features of the DUNE project required to reach its scientific goals.

title: Changes in the cladoceran community as an indicator of climatic variability in the Gulf of Riga, NE Baltic Sea
Creators: name: Ikauniece, Anda
Publisher: name: ASC 2006 - Theme session C
Year: 2024
Subjects: Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Zooplankton in the Gulf of Riga consists of three main groups – calanoid copepods, cladocerans and rotifers. The cladocerans in the Gulf of Riga have an annual abundance maximum in summer when the water temperature reaches the highest level of the year. The shift to earlier peaking than August has been observed starting from mid-1990s and since 1998 has never occurred in August. The main reason of the changed development time is the predation by invasive cladoceran Cercopagis pengoi. Still, the larger scale climatic variability and its local modifications in period of 2000-2005 have affected the dynamics of both prey and predator.

description: In many real-world binary classification tasks (e.g. detection of certain objects from images), an available dataset is imbalanced, i.e., it has much less representatives of a one class (a minor class), than of another. Generally, accurate prediction of the minor class is crucial but it's hard to achieve since there is not much information about the minor class. One approach to deal with this problem is to preliminarily resample the dataset, i.e., add new elements to the dataset or remove existing ones. Resampling can be done in various ways which raises the problem of choosing the most appropriate one. In this paper we experimentally investigate impact of resampling on classification accuracy, compare resampling methods and highlight key points and difficulties of resampling.

Collapse-revivals and population trapping in the m-photon mazer

Year: 2000
Subjects: subject: Quantum Physics (quant-ph)

description: We present a study of collapse-revival patterns that appear in the changes of atomic populations induced by the interaction of ultracold two-level atoms with electromagnetic cavities in resonance with an $m$-photon transition of the atoms ($m$-photon mazer). In particular, sech$^2$ and gaussian cavity mode profiles are considered and differences in the collapse-revival patterns are reported. The quantum theory of the $m$-photon mazer is written in the framework of the dressed-state coordinate formalism. Simple expressions for the atomic populations, the cavity photon statistics, and the reflection and transmission probabilities are given for any initial state of the atom-field system. Evidence for the population trapping phenomenon which suppress the collapse-revivals in the $m$-photon mazer is given.

description: We have analyzed data from the Flat Spectrum Radio Quasar PKS 1510-089 collected over a period of 8 years from August 2008 to December 2016 with the Fermi-LAT. We have identified several flares of this highly variable source, studied their temporal and spectral properties in detail and compared with previous works on flares of PKS 1510-089. Five major flares and few sub-flares/sub-structures have been identified in our study. The fastest variability time is found to be 1.30$\pm$0.18 hr between MJD 55852.063 and 55852.188 where we estimate the minimum size of the emission region to be $4.85 \times 10^{15}$ cm. In most of the flares the spectral energy distributions are better fitted with Logparabolic distribution compared to simple Power law or Power law with exponential cut-offs. This has strong physics implications regarding the nature of the high energy gamma-ray emission region.

Gamma Rays from Molecular Clouds

description: I discuss the spectral features of pi-0 decay gamma-radiation from clouds/targets located in proximity of relatively young proton accelerators, and speculate that such ``accelerator+target'' systems in our Galaxy can be responsible for a subset of unidentified EGRET sources. Also, I argue that the recent observations of high energy gamma-rays from the Orion complex contain evidence that the level of the ``sea'' of galactic cosmic rays may differ significantly from the flux and the spectrum of local (directly detected) particles.
description: The paper is based on presentations at 2 meetings of the workshop on "The Astrophysics of Galactic Cosmic Rays" hosted by the International Space Science Institute, Bern, October 1999 and May 2000; to be published in Space Science Reviews

Tidal effects on stellar activity

description: The architecture of many exoplanetary systems is different from the solar system, with exoplanets being in close orbits around their host stars and having orbital periods of only a few days. We can expect interactions between the star and the exoplanet for such systems that are similar to the tidal interactions observed in close stellar binary systems. For the exoplanet, tidal interaction can lead to circularization of its orbit and the synchronization of its rotational and orbital period. For the host star, it has long been speculated if significant angular momentum transfer can take place between the planetary orbit and the stellar rotation. In the case of the Earth-Moon system, such tidal interaction has led to an increasing distance between Earth and Moon. For stars with Hot Jupiters, where the orbital period of the exoplanet is typically shorter than the stellar rotation period, one expects a decreasing semimajor axis for the planet and enhanced stellar rotation, leading to increased stellar activity. Also excess turbulence in the stellar convective zone due to rising and subsiding tidal bulges may change the magnetic activity we observe for the host star. Here I review recent observational results on stellar activity and tidal interaction in the presence of close-in exoplanets, and discuss the effects of enhanced stellar activity on the exoplanets in such systems.

description: Noise level frequently set the basic limit on the smallest signal. New noise reduction technology and amplifiers voltage-noise density, yet still offer high speed, high accuracy, and low power solution. Low noise amplifiers always play a significant role in RF technology. Hence in this paper, high linear low noise amplifier (LNA) using cascode self-biased multiple gated transistors (MGTR) is presented. The proposed system is covering 0.9 to 2.4 GHz applications. To verify the functionality of the proposed LNA as a bottleneck of RF technology, a cascode LNA without MGTR is implemented and synthesized. Thecomparison has been done with the single-gate LNA. From the synthesized result, proposed LNA obtained 10 dBm third-order input intercept point (IIP3) in compare with single-gate LNA at 9dB gain. The proposed LNA is implemented in 90 nm CMOS technology and reported 13 dBm IIP3, 1.9 dB NF and 9 dB gain while consuming 7.9 mW from 2 V supply.
