Bolivia's 2020 Election: Winning Is Only the Beginning for Luis Arce and The
LSE Latin America and Caribbean Blog: Bolivia’s 2020 election: winning is only the beginning for Luis Arce and the MAS Page 1 of 3 Bolivia’s 2020 election: winning is only the beginning for Luis Arce and the MAS The new MAS government of Luis Arce will be caught between popular expectations of a return to relative prosperity, a growing ecological catastrophe tied to a declining economic model, and a range of social and ideological challenges that pit right-wing religious forces against an increasingly progressive younger generation. But even if the years ahead will show that this victory was in fact the easy part, for now Bolivians have given the world a vital lesson in democracy, writes Bret Gustafson (Washington University in St Louis). Though the official tally is still being finalised, exit polls released around midnight on Sunday 18 October suggest an overwhelming victory for the MAS party in Bolivia, just eleven months after the ouster of Evo Morales. To avoid a run-off, the MAS presidential candidate Luis Arce needed at least 40 per cent of the vote and a ten-point lead over his nearest rival, but this looked like anything but a foregone conclusion in the lead-up to the elections. Luis Arce and his MAS party achieved a sweeping victory just eleven months after Evo Morales was ousted from the presidency (flag removed, Cancillería del Ecuador, CC BY-SA 2.0) Pre-election polling and a divided opposition In the weeks and days before the vote, polling suggested that Carlos Mesa, a right-leaning historian who was briefly president in the early 2000s, stood a good chance of making it to the second round. -
Elecciones 2020: Un Efecto Moderado De La Covid Olivier Dabène
Elecciones 2020: Un efecto moderado de la Covid Olivier Dabène La pandemia ha perturbado el calendario electoral latinoamericano en el primer semestre de 2020. Seis países pospusieron elecciones, por razones que, además, incluían tanto precauciones sanitarias como cálculos políticos. Cuando y donde se celebraron elecciones, las campañas electorales fueron sombrías y la participación recayó en casi todos los países. Sin embargo, este año electoral 2020 no ha estado dominado demasiado por la pandemia. Otros temas han estado en el centro de los debates que explican los resultados.

Higher-Order Interactions in Quantum Optomechanics: Revisiting Theoretical Foundations
Higher-order interactions in quantum optomechanics: Revisiting theoretical foundations Sina Khorasani 1,2 1 School of Electrical Engineering, Sharif University of Technology, Tehran, Iran; [email protected] 2 École Polytechnique Fédérale de Lausanne, Lausanne, CH-1015, Switzerland; [email protected] Abstract: The theory of quantum optomechanics is reconstructed from first principles by finding a Lagrangian from light’s equation of motion and then proceeding to the Hamiltonian. The nonlinear terms, including the quadratic and higher-order interactions, do not vanish under any possible choice of canonical parameters, and lead to coupling of momentum and field. The existence of quadratic mechanical parametric interaction is then demonstrated rigorously, which has been so far assumed phenomenologically in previous studies. Corrections to the quadratic terms are particularly significant when the mechanical frequency is of the same order or larger than the electromagnetic frequency. Further discussions on the squeezing as well as relativistic corrections are presented. Keywords: Optomechanics, Quantum Physics, Nonlinear Interactions 1. Introduction The general field of quantum optomechanics is based on the standard optomechanical Hamiltonian, which is expressed as the simple product of photon number 푛̂ and the position 푥̂ operators, having the form ℍOM = ℏ푔0푛̂푥̂ [1-4] with 푔0 being the single-photon coupling rate. This is mostly referred to a classical paper by Law [5], where the non-relativistic Hamiltonian is obtained through Lagrangian dynamics of the system. This basic interaction is behind numerous exciting theoretical and experimental studies, which demonstrate a wide range of applications. The optomechanical interaction ℍOM is inherently nonlinear by its nature, which is quite analogous to the third-order Kerr optical effect in nonlinear optics [6,7]. -
Nanosystems, Edge Computing, and the Next Generation Computing Systems
sensors Review Nanosystems, Edge Computing, and the Next Generation Computing Systems Ali Passian * and Neena Imam Computing & Computational Sciences Directorate, Oak Ridge National Laboratory, Oak Ridge, TN 37830, USA; [email protected] * Correspondence: [email protected] Received: 30 July 2019; Accepted: 16 September 2019; Published: 19 September 2019 Abstract: It is widely recognized that nanoscience and nanotechnology and their subfields, such as nanophotonics, nanoelectronics, and nanomechanics, have had a tremendous impact on recent advances in sensing, imaging, and communication, with notable developments, including novel transistors and processor architectures. For example, in addition to being supremely fast, optical and photonic components and devices are capable of operating across multiple orders of magnitude length, power, and spectral scales, encompassing the range from macroscopic device sizes and kW energies to atomic domains and single-photon energies. The extreme versatility of the associated electromagnetic phenomena and applications, both classical and quantum, are therefore highly appealing to the rapidly evolving computing and communication realms, where innovations in both hardware and software are necessary to meet the growing speed and memory requirements. Development of all-optical components, photonic chips, interconnects, and processors will bring the speed of light, photon coherence properties, field confinement and enhancement, information-carrying capacity, and the broad spectrum of light into the high-performance computing, the internet of things, and industries related to cloud, fog, and recently edge computing. Conversely, owing to their extraordinary properties, 0D, 1D, and 2D materials are being explored as a physical basis for the next generation of logic components and processors. Carbon nanotubes, for example, have been recently used to create a new processor beyond proof of principle. -

With the constant development in the PCM platform and integration of multiple material platforms, more and more reconfigurable photonic devices and their dynamic regulation have been theoretically proposed and experimentally demonstrated, showing the great potential of PCMs in integrated photonic chips. Here, we review the recent developments in PCMs and discuss their potential for photonic devices. A universal overview of the mechanism of the phase transition and models of PCMs is presented. PCMs have injected new life into on-chip photonic integrated circuits, which generally contain an optical switch, Citation: Wang, X.; Qi, H.; Hu, X.; an optical logical gate, and an optical modulator. -

Wonderful! 100: A Centennial Celebration Published September 18th, 2019 Listen on TheMcElroy.family [theme music plays] Rachel: Hi, this is Rachel McElroy. Griffin: [laughs] Yeah. Okay, Mario. Yeah, I'll hit you up at the after party. Okay, man. Yeah, I'll see you there. Hey, this is Griffin McElroy. Rachel: And this is Wonderful! Griffin: Sorry, it‘s just… [sighs] I know we gotta focus on the show. I know it‘s our big day, but… we‘re on the red carpet, and like… Rachel: Yeah. Griffin: It‘s hard—if Mario Lopez comes up and wants to hang out at the after party, babe, it‘s like, I‘ve made it! Rachel: I know, but let‘s not celebrate our hundredth episode before we‘ve actually recorded it. Griffin: Right, this is the red carpet before the event. We‘re about to go to the first screening of our hundredth episode. For all I know, it could be a disaster. Mario may not want to talk to me after the party, so I need to check that—cash that check. Shit, if this is the energy I bring to ep one hundred, Mario‘s definitely not gonna wanna talk to me. Rachel: [laughs] Griffin: I just wanna tell him what a good job he did playing Greg Louganis in that one Lifetime movie. Rachel: Aw, jeez. Griffin: In that one commercial I saw for it where he asked if there was a blood nipple. Rachel: Yeah. Yeah. Yeah. Griffin: You love that anecdote. Rachel: Yeah. Griffin: Who are you looking forward to seeing today on the big red way? Rachel: Well, Wallace Shawn.
