FET upconverter design using load dependent mixing transconductance
Creators: name: Lord, Joseph Louis Martin
Publisher: name: University of British Columbia
Year: 2010

description: The conversion gain of GaAs MESFET mixers is known to be dependent on the impedances seen by the applied signals and the resulting mixing products at all ports of the device. For an accurate representation, all these loading conditions should be considered; however, the design of gate and drain networks then becomes rather difficult. As a result, no sufficiently accurate and yet usable design procedures exist for MESFET mixers; instead, a few simple rules involving short- and open-circuit terminations have been given by various authors. Unfortunately, these rules are often inappropriate, particularly in upconverter applications. In this thesis, the conversion efficiency dependence on the drain loading at the local oscillator frequency has been studied for a gate upconverter; the local oscillator signal is by far the most dominant in terms of its influence on mixer performance. It has been found that the conversion gain can significantly deteriorate for a narrow range of load values. In addition, the local oscillator drain termination resulting in highest gain has been found to be generally different from the short-circuit recommended in the literature. Based on these findings, a novel FET upconverter design procedure has been developed that incorporates the local oscillator loading phenomenon in the FET equivalent circuit by means of a load dependent mixing transconductance. It allows the optimization of the drain network for an acceptable match at the selected sideband and desired local oscillator rejection while avoiding impedance values in the local oscillator frequency range which would otherwise cause severe degradation in conversion gain.
„Entwicklung heißt Befreiung“: Strategien und Protestformen der schweizerischen Dritte-Welt-Bewegung am Symposium der Solidarität 1981

description: The study’s aim is to illustrate and analyse in depth the different ways development aid policy was debated and protested against in Switzerland at the beginning of the 1980s, taking the 1981 Symposium of Solidarity as its example. On this occasion 3.000 people and eighty different organisations belonging to the Swiss Third World Movement gathered in the Swiss capital of Berne under the heading “Development Means Liberation”, the motto of an event that defined itself as a “Swiss symposium of solidarity”. The participants ultimately issued a manifesto that harshly criticised Switzerland’s development aid policy of the time and the business activities of major Swiss banks and companies, formulating a number of specific demands aimed at the country’s political leaders. The purpose of the symposium was to define a unique set of new political goals for a dawning decade, as much a critique of old approaches as an expression of hope for a new beginning. For the Swiss Third World Movement the event represented the peak of its impact, mobilising more people than ever before and launching many of the topics that were to define the debates to come. It was the raising of these issues – consciously formulated in a way as to ensure impact on the greatest number of people as well as on adherents of other movements – that ultimately transformed the Third World Movement into an important counterforce within Switzerland’s political landscape.

description: We report precision measurements of the gradient of the Casimir force between an Au-coated sphere and graphene sheet deposited on a silica plate. The measurement data are compared with exact theory using the polarization tensor found in the framework of the Dirac model including effects of the nonzero chemical potential and energy gap of the graphene sample with no fitting parameters. The very good agreement between experiment and theory demonstrates the unusually big thermal effect at separations below 1 mum which has never been observed for conventional 3D materials. Thus, it is confirmed experimentally that for graphene the effective temperature is determined by the Fermi velocity rather than by the speed of light.

description: Context: Vela X-1 is one of the best studied X-ray binaries. Frequently though, specific values for its parameters have been used in subsequent studies without considering alternatives. Aims: We aim to provide a robust compilation and synthesis of the accumulated knowledge about Vela X-1 as a solid baseline for future studies and identify specific avenues of possible future research. Methods: We explore the literature for Vela X-1 and on modelling efforts, describing the evolution of the system knowledge. We also add information derived from public data, especially the Gaia EDR3 release. Results: We update the distance to Vela X-1, the spectral classification for HD 77518 and find that the supergiant may be very close to filling its Roche lobe. Constraints on the clumpiness of the stellar wind have improved. The orbit is very well determined, but the uncertain inclination limits information on the neutron star mass. Estimates for the stellar wind have evolved towards lower velocities, supporting the idea of transient wind-captured disks around the neutron star. Hydrodynamic models and observations are consistent with an accretion wake trailing the neutron star. Conclusions: Vela X-1 is an excellent laboratory, but a lot of room remains to improve. Well-coordinated multi-wavelength observations and campaigns addressing the intrinsic variability are required. New opportunities will arise through new instrumentation. Models of the stellar wind should account for the orbital eccentricity and the non-spherical shape of HD 77581. Realistic multi-dimensional models of radiative transfer in the UV and X-rays are needed, but remain very challenging. Improved MHD models covering a wide range of scales would be required to improve understanding of the plasma-magnetosphere coupling. A full characterization of the accretion column remains another open challenge. (Abbreviated for arXiv)

Chinesische Begriffe der Gesellschaft zwischen der ausgehenden Qing-Zeit und den 1920er Jahren: Einige Beobachtungen und Überlegungen

Publisher: name: Moving the Social
Year: 2015

description: This article focuses on the concept of “society” and its changing terms as well as connotations in China between the late nineteenth century and the 1920s. It shows that the concept of society was often seen as a central part of a much wider transformation of China into a modern state and economy. Definitions and terms for “society” were closely wedded to a plethora of fundamental questions about China and the future world at large. Among the most contested issues was the question of what constituted the essence of Chinese society and what demarcated its boundaries. Moreover, there was the problem whether Chinese society would primarily be the result of a great enterprise characterised by radical transformations or whether it would evolve from gradual transformations. Another contested issue was what groups could rightly see themselves as the core of Chinese society, both in the present and in the future.

subject: FOS: Computer and information sciences

description: The effect of removing gamification elements from interactive systems has been a long-standing question in gamification research. Early work and foundational theories raised concerns about the endurance of positive effects and the emergence of negative ones. Yet, nearly a decade later, no work to date has sought consensus on these matters. Here, I offer a rapid review on the state of the art and what is known about the impact of removing gamification. A small corpus of 8 papers published between 2012 and 2020 were found. Findings suggest a mix of positive and negative effects related to removing gamification. Significantly, insufficient reporting, methodological weaknesses, limited measures, and superficial interpretations of "negative" results prevent firm conclusions. I offer a research agenda towards better understanding the nature of gamification removal. I end with a call for empirical and theoretical work on illuminating the effects that may linger after systems are un-gamified.

description: We study thermal effects at the depinning transition by numerical simulations of driven one-dimensional elastic interfaces in a disordered medium. We find that the velocity of the interface, evaluated at the critical depinning force, can be correctly described with the power law $v\sim T^ψ$, where $ψ$ is the thermal exponent. Using the sample-dependent value of the critical force, we precisely evaluate the value of $ψ$ directly from the temperature dependence of the velocity, obtaining the value $ψ= 0.15 \pm 0.01$. By measuring the structure factor of the interface we show that both the thermally-rounded and the T=0 depinning, display the same large-scale geometry, described by an identical divergence of a characteristic length with the velocity $ξ\propto v^{-ν/β}$, where $ν$ and $β$ are respectively the T=0 correlation and depinning exponents. We discuss the comparison of our results with previous estimates of the thermal exponent and the direct consequences for recent experiments on magnetic domain wall motion in ferromagnetic thin films.

description: Artificial intelligences (AI) are increasingly being embodied and embedded in the world to carry out tasks and support decision-making with and for people. Robots, recommender systems, voice assistants, virtual humans - do these disparate types of embodied AI have something in common? Here we show how they can manifest as "socially embodied AI." We define this as the state that embodied AI "circumstantially" take on within interactive contexts when perceived as both social and agentic by people. We offer a working ontology that describes how embodied AI can dynamically transition into socially embodied AI. We propose an ontological heuristic for describing the threshold: the Tepper line. We reinforce our theoretical work with expert insights from a card sort workshop. We end with two case studies to illustrate the dynamic and contextual nature of this heuristic.

description: Weak-coupling conserving approximations can be constructed by truncations of the Luttinger-Ward functional and are well known as thermodynamically consistent approaches which respect macroscopic conservation laws as well as certain sum rules at zero temperature. These properties can also be shown for variational approximations that are generated within the framework of the self-energy-functional theory without a truncation of the diagram series. Luttinger's sum rule represents an exception. We analyze the conditions under which the sum rule holds within a non-perturbative conserving approximation. Numerical examples are given for a simple but non-trivial dynamical two-site approximation. The validity of the sum rule for finite Hubbard clusters and the consequences for cluster extensions of the dynamical mean-field theory are discussed.

Two-dimensional hybrid model of gradient drift instability and enhanced electron transport in a Hall thruster

description: An axial-azimuthal two-dimensional Hall thruster discharge model was developed for analyzing gradient drift instability (GDI) and cross-field electron transport enhancement induced solely by the GDI. A hybrid particle-fluid model was used for the partially ionized plasma, where the inertialess electron fluid in the quasineutral plasma was assumed. A nonoscillatory numerical method was proposed for the potential solver in the electron fluid model to avoid numerical instability and analyze the physics of GDI accurately. A simulation is performed for a 1 kW-class anode-layer-type Hall thruster, and the flow field with plasma instability is presented. Plasma instability with vortex-like structures is observed in the acceleration and plume regions. The generated plasma instability enhances the cross-field electron transport in the axial direction around the channel exit and in the plume region. Grid convergence is confirmed regarding the effect of electron transport enhancement, which indicates that cross-field electron transport enhancement is based on the plasma instability. Furthermore, the comparison between the simulation results and linear perturbation analyses demonstrates that the simulated plasma instability reflects the theory of GDI. Thus, it is concluded that the hybrid model is useful for the analyses of GDI, and the GDI can enhance the cross-field electron transport in Hall thrusters.

Restarted activity in the 3C328 radio galaxy
Creators: name: Marecki, A.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: As a rule, both lobes of Fanaroff-Riley (FR) type-II radio sources are terminated with hotspots, but the 3C328 radio galaxy is a specimen of an FR II-like object with a hotspot in only one lobe. A conceivable reason for such asymmetry is that the nucleus of 3C328 was temporarily inactive. There was no energy transfer from it to the lobes during the period of quiescence, and so they began to fade out. However, under the assumption that the axis connecting the two lobes makes an appreciable angle with the sky plane, and hence one is considerably farther from the observer than the other, the lobes are observed at two distinct stages of evolution due to the light-travel lag. While the far-side lobe is still perceived as being of the FR II type with a hotspot, decay of the near-side lobe is already apparent. No jets are visible in the VLA images, but the VLBA observations of the inverted-spectrum core component of 3C328 have revealed that it has a jet of a sub-arcsecond length pointing towards the lobe that shows evidence of decay. Since the jet always points to the near side, its observed orientation is in line with the scenario proposed here. The presence of the jet supports the inference that the nucleus of 3C328 is currently active; however, given the fact that the jet is short (approx. 200 pc in projection), the activity must have restarted very recently. The lower and upper limits of the quiescent period length have been calculated.

Vaccines Against SARS-CoV-2 and Intrahost Viral Adaptations
Creators: name: Class, Jacob
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The SARS-CoV-2 pandemic lasted from March 2020 to May 2023 and claimed over seven million lives worldwide. The virus was not eliminated but instead is now considered an endemic pathogen with seasonal spikes. Vaccination and treatment options have reduced hospitalization and mortality, but protection is short lived and continued viral mutations increase risk of reinfection. Further investigation into long lasting vaccination and mechanisms behind SARS-CoV-2 evolution are essential in limiting current or future coronavirus outbreaks. Here we examine how the use of alternative coronavirus antigens, excluding the SARS-CoV-2 Spike protein, alters duration and cross-reactivity of protection. We found that SARS-CoV-2 Nucleocapsid protein limited viral dissemination and provides partial protection against infection. Additionally, vaccination with SARS-CoV Spike protein reduced viral titers upon subsequent SARS-CoV-2 challenge. Afterwards, we evaluated the effect of vaccination on viral evolution. Preexisting immunity did not influence acute viral diversity; however, there was increased viral diversity within the CNS, where we observed negative selection against the furin cleavage site (FCS). Deletion of the FCS altered viral entry and resulted in tissue specific attenuation of SARS-CoV-2. We also found evidence of positive selective pressure for the FCS within the lung, indicating there are compartment specific drivers for viral adaptations. Intrahost adaptations, such as the deletion of the FCS, could explain non-respiratory symptoms seen in COVID-19 and PASC patients. In addition, the compartment specific selective pressures on SARS-CoV-2 may be related to development of variants of concern (VOCs), especially in immunocompromised patients who experience prolonged infections. These finding indicates that alternative Coronavirus antigens, not just from SARS-CoV-2, should be evaluated in pan-coronavirus vaccine development. Furthermore, our data provides insight into the pathways driving long-COVID and generation of VOCs.

description: We consider an interaction-driven scenario for the two-dimensional metal-insulator transition in zero magnetic field (2D-MIT), based on melting the Wigner crystal through vacancy-interstitial pair formation. We show that the transition from the Wigner-Mott insulator to a heavy Fermi liquid emerges as an instability to self-doping, resembling conceptually the solid to normal liquid transition in He3. The resulting physical picture naturally explains many puzzling features of the 2D-MIT.

description: We explore the electronic properties of finite-length graphene nanoribbons as well as graphene nanodisks with various sizes and shapes in quest of metallic ones. For this purpose it is sufficient to search zero-energy states. We find that there exist no zero-energy states in finite-length zigzag nanoribbons though all infinite-length zigzag nanoribbons have zero-energy states. The occurrence of zero-energy states is surprisingly rare. Among typical nanodisks, only trigonal zigzag nanodisks have degenerate zero-energy states and show metallic ferromagnetism, where the degeneracy can be controlled arbitrarily by designing the size. A remarkable property is that the relaxation time is quite large in spite of its small size in trigonal zigzag nanodisks.

Adaptive compression coding

description: An adaptive image compression coding technique, ACC, is presented. This algorithm is shown to preserve edges and give better quality decompressed pictures and better compression ratios than that of the Absolute Moment Block Truncation Coding. Lookup tables are used to achieve better compression rates without affecting the visual quality of the reconstructed image. Regions with approximately uniform intensities are successfully detected by using the range and these regions are approximated by their average. This procedure leads to further reduction in the compression data rates. A method for preserving edges is introduced. It is shown that as more details are preserved around edges the pictorial results improve dramatically. The ragged appearance of the edges in AMBTC is reduced or eliminated, leading to images far superior than those of AMBTC. For most of the images ACC yields Root Mean Square Error smaller than that obtained by AMBTC. Decompression time is shown to be comparable to that of AMBTC for low threshold values and becomes significantly lower as the compression rate becomes smaller. An adaptive filter is introduced which helps recover lost texture at very low compression rates (0.8 to 0.6 b/p, depending on the degree of texture in the image). This algorithm is easy to implement since no special hardware is needed.

description: We introduce the notion of entanglement of subspaces as a measure that quantify the entanglement of bipartite states in a randomly selected subspace. We discuss its properties and in particular we show that for maximally entangled subspaces it is additive. Furthermore, we show that maximally entangled subspaces can play an important role in the study of quantum error correction codes. We discuss both degenerate and non-degenerate codes and show that the subspace spanned by the logical codewords of a non-degenerate code is a 2k-totally (maximally) entangled subspace. As for non-degenerate codes, we provide a mathematical definition in terms of subspaces and, as an example, we analyze Shor's nine qubits code in terms of 22 mutually orthogonal subspaces.

description: Zero-point fluctuations are a universal consequence of quantum theory. Vacuum fluctuations of electromagnetic field have provided crucial evidence and guidance for QED as a successful quantum field theory with a defining gauge symmetry through the Lamb shift, Casimir effect, and spontaneous emission. In an accelerated frame, the thermalisation of the zero-point electromagnetic field gives rise to the Unruh effect linked to the Hawking effect of a black hole via the equivalence principle. This principle is the basis of general covariance, the symmetry of general relativity as the classical theory of gravity. If quantum gravity exists, the quantum vacuum fluctuations of the gravitational field should also lead to the quantum decoherence and dissertation of general forms of energy and matter. Here we present a novel theoretical effect involving the spontaneous emission of soft gravitons by photons as they bend around a heavy mass and discuss its observational prospects. Our analytic and numerical investigations suggest that the gravitational bending of starlight predicted by classical general relativity should also be accompanied by the emission of gravitational waves. This in turn redshifts the light causing a loss of its energy somewhat analogous to the bremsstrahlung of electrons by a heavier charged particle. It is suggested that this new effect may be important for a combined astronomical source of intense gravity and high-frequency radiation such as X-ray binaries and that the proposed LISA mission may be potentially sensitive to the resulting sub-Hz stochastic gravitational waves.

Consistent Individual Differences in Social and Solitary Foraging Within Disparate Taxa

description: Any pet owner can tell you that their pet is unique. They have behavioral traits that are consistent over time that also make them different from other pets. However, until recently ecological studies have dismissed individual differences in behavior as statistical noise around an adaptive mean. This has changed in the last few decades, as more and more often consistent individual differences, or personalities, are being treated as an evolutionary “feature” rather than a “bug. Foraging is an ecologically important behavioral context in which animals should exhibit consistent individual differences. I examined individual-level foraging in three dissimilar taxa: a solitary crustacean, the rusty crayfish (Faxonius rusticus), a eusocial rodent, the naked mole-rat (heterocephalus glaber), and a colonial chiropteran, the Egyptian fruit bat (Rousettus aegyptiacus). Individual rusty crayfish varied in their foraging behavior but were consistent over time. They also harvested more food but were more neophobic than a native conspecific they are displacing, the Northern clearwater crayfish (F. propinquus). In naked mole-rats, foraging effort is concentrated in just a few mid-sized individuals, and their inefficient foraging strategies suggested a lack of information sharing. Naked mole-rats also exhibited clear personalities, but the relationship between personality and size varied between colonies. Finally, in Egyptian fruit bats, male-female pairs foraged more efficiently than same-sex pairs. However, foraging was affected more by the identity and compatibility of individuals than on sex or social context. Overall, these results suggest foraging behavior is not just a relevant context in which animals show consistent individual differences, but an overlooked method by which to measure them.

description: We develop here a novel modelling approach with the aim of closing the conceptual gap between tumour-level metabolic processes and the metabolic processes occurring in individual cancer cells. In particular, the metabolism in hepatocellular carcinoma derived cell lines (HEPG2 cells) has been well characterized but implementations of multiscale models integrating this known metabolism have not been previously reported. We therefore extend a previously published multiscale model of vascular tumour growth, and integrate it with an experimentally verified network of central metabolism in HEPG2 cells. This resultant combined model links spatially heterogeneous vascular tumour growth with known metabolic networks within tumour cells and accounts for blood flow, angiogenesis, vascular remodelling and nutrient/growth factor transport within a growing tumour, as well as the movement of, and interactions between normal and cancer cells. Model simulations report for the first time, predictions of spatially resolved time courses of core metabolites in HEPG2 cells. These simulations can be performed at a sufficient scale to incorporate clinically relevant features of different tumour systems using reasonable computational resources. Our results predict larger than expected temporal and spatial heterogeneity in the intracellular concentrations of glucose, oxygen, lactate pyruvate, f16bp and Acetyl-CoA. The integrated multiscale model developed here provides an ideal quantitative framework in which to study the relationship between dosage, timing, and scheduling of anti-neoplastic agents and the physiological effects of tumour metabolism at the cellular level. Such models, therefore, have the potential to inform treatment decisions when drug response is dependent on the metabolic state of individual cancer cells.

description: Several hard exclusive scattering processes admit a description in terms of generalized parton distributions and perturbative hard-scattering kernels. Both the physical amplitude and the hard-scattering kernels fulfill dispersion relations. We give a detailed investigation of their consistency at all orders in perturbation theory. The results shed light on the information about generalized parton distributions that can be extracted from the real and imaginary parts of exclusive amplitudes. They also provide a practical consistency check for models of these distributions in which Lorentz invariance is not exactly satisfied.

Modelling of coupled surface and subsurface water flows

Year: 2021
Subjects: subject: Numerical Analysis (math.NA)

description: In this paper, we propose to use the HLL finite volume scheme combined with implicit techniques for modelling the coupled surface and subsurface water flows. In our approach, we used the shallow water equations modelling surface water flow with different source terms such as variable bottom topography, friction effect, precipitation and infiltration. For subsurface water flow, the Green-Amp equation is used to simulate the infiltration process through soils. For solving the resulting nonlinear-coupled system of shallow water flow and the Green-Ampt infiltration equations, the HLL finite volume schemes with linear reconstructions of the solutions at the discrete level are implemented in order to achieve the second-order accuracy of the scheme. Appropriate discretization techniques are used for the source terms to guarantee the well-balanced property of our numerical scheme. Numerical experiments are performed to test the capability of the developed numerical scheme to simulate the coupled surface and subsurface water flows.

description: Pressure-induced phase transitions of spin-crossover materials were simulated by a Monte Carlo simulation in the constant pressure ensemble for the first time. Here, as the origin of the cooperative interaction, we adopt elastic interaction among the distortions of the lattice due to the difference of the molecular sizes in different spin states, i.e., the high spin (HS) state and the low spin (LS) state. We studied how the temperature dependence of the ordering process changes with the pressure, and we obtained a standard sequence of temperature dependences that has been found in changing other parameters such as strength of the ligand field (S. Miyashita et al., Prog. Theor. Phys. \textbf{114}, 719 (2005)). Various effects of pressure on the spin-crossover ordering process are examined from a unified point of view.

Intrinsic Zeeman Effect in Graphene

description: The intrinsic Zeeman energy is precisely one half of the cyclotron energy for electrons in graphene. As a result a Landau-level mixing occurs to create the energy spectrum comprised of the $4j$-fold degenerated zero-energy level and 4-fold degenerated nonzero-energy levels in the $j$-layer graphene, where $j=1,2,3$ for monolayer, bilayer and trilayer, respectively. The degeneracy manifests itself in the quantum Hall (QH) effect. We study how the degeneracy is removed by the Coulomb interactions. With respect to the zero-energy level, an excitonic gap opens by making a BCS-type condensation of electron-hole pairs at the filling factor $ν=0$. It gives birth to the Ising QH ferromagnet at $ν=\pm 1$ for monolayer, $ν=\pm 1,\pm 3$ for bilayer, and $ν=\pm 1,\pm 3,\pm 5$ for trilayer graphene from the zero-energy degeneracy. With respect to the nonzero-energy level, a remarkable consequence is derived that the effective Coulomb potential depends on spins, since a single energy level contains up-spin and down-spin electrons belonging to different Landau levels. The spin-dependent Coulomb interaction leads to the valley polarization at $ν=\pm 4, \pm 8, \pm 12, ...$ for monolayer, $ν=\pm 2, \pm 6, \pm 10, >...$ for bilayer, and $ν=\pm 2,\pm 4, \pm 8, \pm 12, ...$ for trilayer graphene.
