description: The tension between health and economic considerations regarding COVID-19 has resulted in a framing contest, in which proponents and adversaries of strong containment measures hold oppositional frames about the pandemic. This study examines the effects of competing news frames on social media users' policy preferences and the moderation of framing effects played by melodramatic news treatment. Results from a pre-registered online survey experiment in Chile (N = 518) show that participants exposed to Facebook posts with an economic frame were significantly less supportive of measures that restrict mobility (e.g., quarantines) than participants in the control group. Contrary to expectations, exposure to a public health frame also reduced support for stay-at-home orders, and the presence of melodramatic features had no significant impact on users' preferences. Other variables, however, did alter these framing effects, such as fear of COVID-19 and frequency of social media news use. These findings paint a rather complex picture of framing effects during the pandemic in a digital media environment.
A trivial observation on time reversal in random matrix theory

description: It is commonly thought that a state-dependent quantity, after being averaged over a classical ensemble of random Hamiltonians, will always become independent of the state. We point out that this is in general incorrect: if the ensemble of Hamiltonians is time reversal invariant, and the quantity involves the state in higher than bilinear order, then we show that the quantity is only a constant over the orbits of the invariance group on the Hilbert space. Examples include fidelity and decoherence in appropriate models.

Acryptolaria angulata.− Blackburn 1942: 111.− Vervoort and Watson 2003: 41 (synonymy).
Record. QM G337451, microslide. Coll: off Fraser Island, Queensland, 25.3253 S, 154.0683 E to 25.3513 S, 154.076 E, 2350– 2342 m, beam trawl, 11/06/2017.
Description. A small infertile colony 30 mm long with remnant hydrorhizal stolons. Stem fascicled, polysiphonic tubes thin, irregularly parallel, of same diameter as stolon.
Hydrothecae given off all around stem, tubular, a sharp outward bend in hydrotheca at junction of abcauline wall with stem; some hydrothecae widening almost imperceptibly to margin. Margin circular, everted, rim minutely outrolled; margin usually with many replications.
Perisarc throughout (preserved material) thin and lax.
Remarks. The strengthening buttresses reported in Acryptolaria angulata by Vervoort and Watson (2003) are actually abcauline intrathecal septa; these do not occur in the present specimen. Septae probably develop to strengthen the hydrotheca in strong water movement, not encountered by specimens in quieter deep-water conditions. The marginal replications of the hydrothecae considerably extends their length.
Distribution. A widespread deep-water species recorded from the Indian Ocean, New Caledonia and rarely, New Zealand. The deepest previous record for the species is 913 m at the Kermadec Ridge.

Exploring Real-Time Architectures for ALMA Antenna Control Systems
Creators: name: Brandt, Patrick
Publisher: name: Zenodo
Year: 2019

description: With the antenna control hardware nearing its obsolescence point, it is an advantageous time to explore alternate architectures for the future of ALMA. A recent project to upgrade the real-time operating system that runs on these computers has given the ICT a renewed knowledge of both the details of these systems, and of the shortcomings inherent in the current hardware and software which manages the timing signals and CANbus.

We would like to explore splitting the real-time and non real-time components of both the hardware and software away from one another. The goal is to reduce future maintenance, avoid introducing subtle bugs through periodic operating system upgrades, and pave the way towards using Ethernet for software-to-hardware communications.

Included will be a broader discussion of how to manage obsolescence in other areas of software, such as the code generation for the ASDM and APDM.

description: We conducted interferometric observations with the CHARA Array of transiting super-Earth host HD 97658 and measured its limb-darkened angular diameter to be $θ_{\text{LD}}=0.314\pm0.004$ mas. The combination of the angular diameter with the Gaia EDR3 parallax value with zero-point correction ($π=46.412\pm0.022$ mas, $d=21.546\pm0.011$ pc) yields a physical radius of $R_\star=0.728\pm0.008$ $R_\odot$. We also measured the bolometric flux of the star to be $F_\text{bol}=2.42\pm 0.05\times 10^{-8}$erg s$^{-1}$ cm$^{-2}$, which, together with angular size, allows a measurement of the effective temperature $T_{\text{eff}}=5212\pm43$ K. Our directly determined physical stellar properties are in good agreement with previous estimates derived from spectroscopy. We used our measurements in combination with stellar evolutionary models and properties of the transit of HD 97658 b to determine the mass and age of HD 97658 as well as constrain the properties of the planet. Our results and our analysis of the TESS lightcurve on the planet (TOI-1821) corroborate previous studies of this system with tighter uncertainties.

On the Generation of Long Binary Sequences with Record-Breaking PSL Values
Creators: name: Dimitrov, Miroslav

name: Nikolov, Nikolay
Publisher: name: arXiv
Year: 2021
Subjects: subject: Signal Processing (eess.SP)

description: Binary sequences are widely used in various practical fields, such as telecommunications, radar technology, navigation, cryptography, measurement sciences, biology or industry. In this paper, a method to generate long binary sequences (LBS) with low peak sidelobe level (PSL) value is proposed. Having an LBS with length $n$, both the time and memory complexities of the proposed algorithm are $\mathcal{O}(n)$. During our experiments, we repeatedly reach better PSL values than the currently known state of art constructions, such as Legendre sequences, with or without rotations, Rudin-Shapiro sequences or m-sequences, with or without rotations, by always reaching a record-breaking PSL values strictly less than $\sqrt{n}$. Furthermore, the efficiency and simplicity of the proposed method are particularly beneficial to the lightweightness of the implementation, which allowed us to reach record-breaking PSL values for less than a second.

Is there a partition in the present indicative of Italian regular verbs?
Creators: name: Thornton, Anna M.
Publisher: name: Annali Online  Lettere - Ferrara
Year: 2012

description: Nel modello di analisi morfologica della Morphology by Itself, proposto  da Aronoff (1994), i paradigmi flessivi possono presentarsi internamente  organizzati in "classi di partizione", cioè insiemi di celle occupati  da forme flesse costruite a partire da una stessa base (stem), ma che  non condividono tratti sintattici. Nel verbo romanzo, una classe di  partizione molto frequente (denominata "N-pattern" da Maiden) è quella  che raggruppa le prime tre persone del singolare e la terza plurale del  presente indicativo, ma esclude prima e seconda plurale. Questa  partizione è evidente in molti verbi italiani, che presentano alternanze  tra forme dittongate e non (ad es. in sedere), tra forme con -isc- e  senza (ad es. in finire), o alternanze suppletive specifiche di singoli  verbi (uscire, udire, andare). Nel lavoro si sostiene che questa  partizione sottende anche l'organizzazione del presente indicativo dei  verbi regolari della prima coniugazione (come già sostenuto in forma  embrionale in Dressler - Thornton [1991]). La proposta, formulata dopo  una revisione delle analisi precedenti di Dressler - Thornton (1991) e  Pirrelli (2000), comprende una nuova analisi della costituzione delle  forme di prima e terza persona plurale.

description: This article explores the uses of sources in coverage of the COVID-19 pandemic in social media posts of mainstream news organizations in Brazil, Chile, Germany, Mexico, Spain, the U.K., and the U.S. Based on computational content analysis, our study analyzes the sources and actors present in more than 940,000 posts on COVID-19 published in the 227 Facebook, Instagram, and Twitter accounts of 78 sampled news outlets between January 1 and December 31 of 2020, comparing their relative importance across countries, across media platforms, and across time as the pandemic evolved in each country. The analysis shows the dominance of political sources across countries and platforms, particularly in Latin America, demonstrating a strong role of the state in constructing pandemic news and suggesting that mainstream news organizations' social media posts maintain a strong elite orientation. Health sources were also prominent — consistent with the defining role of biomedical authority in health coverage—, while significant diversity of sources, including citizen sources, emerged as the pandemic went on. Our results also revealed that the use of specific sources significantly varied over time. These variations tend to go hand in hand with specific global milestones of the pandemic.

description: In this paper, we present an unsupervised learning approach to identify the user points of interest (POI) by exploiting WiFi measurements from smartphone application data. Due to the lack of GPS positioning accuracy in indoor, sheltered, and high rise building environments, we rely on widely available WiFi access points (AP) in contemporary urban areas to accurately identify POI and mobility patterns, by comparing the similarity in the WiFi measurements. We propose a system architecture to scan the surrounding WiFi AP, and perform unsupervised learning to demonstrate that it is possible to identify three major insights, namely the indoor POI within a building, neighbourhood activity, and micro-mobility of the users. Our results show that it is possible to identify the aforementioned insights, with the fusion of WiFi and GPS, which are not possible to identify by only using GPS.

description: We investigate the system constituted by a polarizable atom near a nanosphere under the influence of an external electrostatic field, showing that the attractive dispersive force between them can be overcome by the electrostatic interaction. Therefore, in addition to the advantageous possibility of actively tuning the resultant force with an external agent without the requirement of physical contact, this force may also become repulsive. We analyze this situation in different physical regimes of distance and explore the interaction of different atoms with both metallic and dielectric spheres, discussing which cases are easier to control. Furthermore, our results reveal that these repulsive forces can be achieved with feasible field intensities in the laboratory.
Digital Front-End Development for ALMA
Creators: name: Baryshev, Andrey
Publisher: name: Zenodo
Year: 2019

description: Improvement of ALMA observatory requires increase of bandwidth, sensitivity and number of antennas. All these improvements will meet a bottleneck if ALMA digital system is not addressed. Currently a 2 bit digitizer supporting <8 GHz bandwidth per polarization is employed limiting correlation efficiency at 88%. Implementation of ALMA downconverter substantially limits line searches compared to sensitivity limit and it's bandwidth is not extendable.  We have initiated study on possible implementation of ALMA digital front-end system which includes modular digitizer, digital processing at antenna and TCP/IP optical fiber data transfer. We report on requirements, trade-offs and possible implementation of modular digital front-end and analyze its impact on sensitivity of current ALMA system as well as future one. We review technology and performance available in near future. Significant performance improvement can be realized at moderate cost.

description: We make a search for Halpha emitting galaxies at z=0.24 in the Subaru Deep Field (SDF) using the archival data set obtained with the Subaru Telescope. We carefully select Halpha emitters in the narrowband filter NB816, using B, V, Rc, i', and z' broad-band colors. We obtain a sample of 258 emitting galaxies with observed equivalent widths of (Halpha+[NII]6548,6584) greater than 12 angstrom. We also analyze a sample of Halpha emitters taken from the Sloan Digital Sky Survey (SDSS) to constrain the luminous end of Halpha luminosity function. Using the same selection criteria as for the SDF, and after excluding AGNs, we obtain 317 Halpha emitting star-forming galaxies. Combining these two samples of Halpha emitters found in both SDF and SDSS, we derive a Halpha luminosity function with best-fit Schechter function parameters of alpha = -1.31^+0.17_-0.17, log phi^* = -2.46^+0.34_-0.40 Mpc^-3, log L^* = 41.99^+0.08_-0.07 ergs s^-1. An extinction-corrected Halpha luminosity density is 4.45^+2.96_-1.75 x 10^39 ergs s^-1 Mpc^-3. Using the Kennicutt relation between the Halpha luminosity and star formation rate, the star formation rate density in the survey volume is estimated as 0.035^+0.024_-0.014 M_sun yr^-1 Mpc^-3. The angular two-point correlation function of Halpha emitters over 875 arcmin^2 at z = 0.24 is well fitted by a power-law form with w(theta) = 0.047^+0.017_-0.013 theta^-0.66 +- 0.08, corresponding to the correlation function of xi(r) = (r/2.6^+1.0_-0.8 Mpc)^(-1.66 +- 0.08). The small correlation length of Halpha emitters may imply the weak clustering of active star-forming galaxies.

Dal Land Walking alla Locative Art, passi e segni sulla mappa
Creators: name: Berti, Paolo
Publisher: name: Annali Online  Lettere - Ferrara
Year: 2014
Subjects: arte ambientale; land art; locative art; percorsi pedestri; cartografia

description: The dissertation begins with a specific declination of Land Art, quintessentially English, mostly linked to the experience of journey, overcoming simple plastic representation to be pure action, putting the man and his physicality in the foreground as the “measurement instrument” of the Earth.

Fifties landscape culture as modern minimalist Wanderung is very strong and some ideas on how to use maps and cartography in an artistic sense begin to be understood as well as language translations. After analysing some works more closely linked to the geographical representation, we’ll notice how the experiential aspects of walking and cartography have in recent years found a creative meeting point through new digital technologies, in an area called Locative Art.

description: Background: Hydroxychloroquine (HCQ) was proposed as potential treatment for COVID-19, but its association with mortality is unclear. We reviewed published literature for evidence of an association between HCQ (with or without azithromycin (AZM)) and total mortality in COVID-19 patients. Methods: Articles were retrieved until April 29th, 2021 by searching in seven databases. Data were combined using the general-variance-based method. Results: A total of 25 cohort studies (N=41,339 patients) and 11 randomized clinical trials (RCTs; N=8,709) were found. The use of HCQ was not associated with mortality in meta-analysis of RCTs (pooled risk ratio (PRR): 1.08, 95%CI: 0.97-1.20; I2=0%), but it was associated with 20% lower mortality risk (PRR=0.80, 95%CI: 0.69-0.93; I2=80%) in pooling of cohort studies. The negative association with mortality was mainly apparent by pooling cohort studies that used lower doses of HCQ (≤400 mg/day; PRR=0.69, 95%CI: 0.57-0.87). Use of HCQ+AZM (11 studies) was associated with 25% non-statistically significant lower mortality risk (PPR=0.75; 0.51-1.10; P=0.15). Use of HCQ was not associated with severe adverse events (PRR=1.12, 95%CI: 0.88-1.44; I2=0%). Conclusions: HCQ use was not associated with mortality in COVID-19 patients in pooling results from RCTs (high level of certainty of evidence), but it was associated with 20% mortality reduction when findings from observational studies were combined (low level of certainty of evidence). The reduction of mortality was mainly apparent in observational studies where lower doses of HCQ were used. These findings might help disentangling the debate on HCQ use in COVID-19.

description: We reconsider the calculation of rovibrational transition frequencies in hydrogen molecular ions. Some previously neglected contributions, such as the deuteron polarizability, are included into consideration in comparison with our previous work. In particular, one-loop and two-loop QED corrections at $mα^7$ and $mα^8$ orders are recalculated in the framework of the adiabatic approximation, with systematic inclusion of corrections associated with vibrational motion. Improved theoretical transitions frequencies are obtained and found to be in very good agreement with recent high-precision spectroscopy experiments in HD$^+$. New values for the $m_p/m_e$ and $m_d/m_p$ mass ratios are determined.

A Proposed Upgrade to the ALMA Observing Tool
Creators: name: Biggs, Andrew
Publisher: name: Zenodo
Year: 2019

description: The ALMA Observing Tool (OT) has been used since the beginning of ALMA operations to submit proposals and to create Scheduling Blocks for subsequent execution at the telescope. The OT has been a great success, with over eleven thousand proposals having been submitted up to 2018's Cycle 6. However, as development started in 2002, the tool is in need of an update in order to keep up with rapidly advancing technologies and to combat obsolescence and deprecation of existing components. I will report on a recently completed ALMA Upgrade Study that has investigated options for a new-generation OT and which it is hoped will lead to an approved ALMA Development Project later this year.

Description. Three damaged stolonal hydrothecae creeping on stem of Zygophylax concinna. Stolon fragmented, very thin, tubular. Hydrothecal pedicel long, unsegmented. Hydrotheca long, expanding from a narrow conical base to diaphragm then gradually becoming tubular. Diaphragm a distinct perisarcal ring. Margin circular, rims fragmented.
Perisarc thin and fragile.
Remarks. Although there are no hydrothecae with intact margins, sufficient remains to provide an estimate of marginal diameter. Although morphologically similar to Hebella ritchiei Vervoort, 1966 (= Lafoea tenellula Ritchie, 1911) from coastal New South Wales, the hydrothecae of the present material are much larger. The material is inadequate to ascribe it to a new species.

description: We calculate the parametrically dominant next-to-next-to-leading order corrections to four-fermion production e^- e^+ -> mu^- nubar_mu u dbar + X at centre-of-mass energies near the W-pair production threshold employing the method of unstable-particle effective theory. In total the correction is small, leading to a shift of 3 MeV in the W-mass measurement. We also discuss the implementation of realistic cuts and provide a result for the interference of single-Coulomb and soft radiative corrections that can easily be extended to include an arbitrary number of Coulomb photons.

description: Qubits on solid state devices could potentially provide the rapid control necessary for developing scalable quantum information processors. Materials innovation and design breakthroughs have increased functionality and coherence of qubits substantially over the past two decades. Here we show by improving interface between InAs as a semiconductor and Al as a superconductor, one can reliably fabricate voltage-controlled Josephson junction field effect transistor (JJ-FET) that can be used as tunable qubits, resonators, and coupler switches. We find that band gap engineering is crucial in realizing a two-dimensional electron gas near the surface. In addition, we show how the coupling between the semiconductor layer and the superconducting contacts can affect qubit properties. We present the anharmonicity and coupling strengths from one and two-photon absorption in a quantum two level system fabricated with a JJ-FET.

description: Recent advances in topologically robust waveguiding for electromagnetic systems have presented opportunities for improving practical photonic and microwave devices. To bring this rich area of physics within the reach of application, it is critical for such systems to be interfaced with classical, continuous waveguiding and transmission line technology. This Letter presents a compact, highly efficient transition from a classical metallic transmission line to a topologically nontrivial line wave emulating the quantum spin Hall effect. A zero-gap antipodal slot line is used as the starting transmission line, which is then coupled to the topological metasurface via a field matching procedure. Additional modifications to the interface between the two structures to eliminate unwanted edge coupling improves transmission further. A simulated loss analysis isolates the effect of the transitions from the rest of the structure, showing a loss contribution of only 2.1% per classical-to-topological conversion. Using the transition, a quantitative characterization of the robustness of common topologically protected devices is presented. This design lays the foundation to integrate topologically robust metasurface transmission lines to traditional systems, opening the door to future uses of such structures in systems.

description: We demonstrate unusual features of phase dynamics, IV-characteristics and magnetization dynamics of the $φ_0$ Josephson junction at small values of spin-orbit interaction, ratio of Josephson to magnetic energy and Gilbert damping. In particular, an anomalous shift of the ferromagnetic resonance frequency with an increase of Gilbert damping is found. The ferromagnetic resonance curves show the Duffing oscillator behaviour, reflecting the nonlinear nature of Landau-Lifshitz-Gilbert (LLG) equation. Based on the numerical analysis of each term in LLG equation we obtained an approximated equation demonstrated both damping effect and Duffing oscillator features. The resulting Duffing equation incorporates the Gilbert damping in a special way across the dissipative term and the restoring force. A resonance method for the determination of spin-orbit interaction in noncentrosymmetric materials which play the role of barrier in $φ_0$ junctions is proposed.
Parton Energy Loss Without Transverse Momentum Broadening

description: The JEWEL 1.0 Monte Carlo simulates jet evolution in a medium with a microscopic description of splitting and scattering processes. In the framework of this model we investigate the transverse momentum broadening due to medium effects in different scenarios. Depending on assumptions about hadronisation, we observe either a small increase or even a slight decrease of the mean transverse momentum, but no sizeable broadening. This appears to be a natural consequence of a model formulation which conserves energy and momentum microscopically at each splitting and at each scattering.

description: A mensuração da aprendizagem tem sido um processo muito discutido entre os estudiosos e pedagogos, com base na validade de medir o conhecimento ou na utilização desta medida como meio de posicionar o aluno na escala de conhecimento por ele adquirido. Nesta pesquisa foi realizado um estudo observacional descritivo transversal exploratório, através da análise da legislação sobre avaliação, sua materialização, efetividade e fiabilidade, com base na descrição dos conceitos, medidas, modalidades e métodos de avaliação, assim como sua utilização e função, além de avaliar a compreensão do conceito de avaliação entre no campo de estudo e abordar os tipos de avaliação aplicados. Observou-se que na população estudada mais de metade (60%) dos inquiridos era do 1º ano e a frequência mais elevada (45,5%) era de repetentes, sendo que a maioria não conhecia a legislação sobre a avaliação (71,4%), alguns não a compreendiam (59,38%) e outros mal a interpretavam (58,3%), não tinham conhecimento do peso da avaliação (91%) e esta não correspondia aos objetivos educacionais. Afirmara que a prova escrita avaliava adequadamente a reflexão e o raciocínio (57,1%), porém não as competências profissionais (50%), os exames não refletiam os objetivos e os conteúdos das disciplinas (66,96%). As provas escritas, oral e mista foram as mais utilizadas na avaliação, sendo a periódica-contínua a modalidade de avaliação mais usada. A fórmula de avaliação final não era conhecida pela maioria (65,2%), o calendário de exames não considerava o tempo de preparação das provas (84,82%). Os objetivos não eram explicados antes do início das disciplinas (67%), os seminários foram os trabalhos que mais contaram para a avaliação (92,9%), os exames de época normal (95,5%) e os recursos (87,5%) foram os mais realizados, sendo o aproveitamento dos alunos do 1º e 2º ano satisfatório no ano académico de 2005/2006, no ciclo básico, apesar do alto índice de reprovações em algumas cadeiras. Os professores conheciam a legislação, mas apenas 28,6% de estudantes tinham o respetivo conhecimento. Conclui-se que o sistema de avaliação, em alguns dos seus articulados, não tem sido posto em prática. Neste sentido, deve haver rigor no cumprimento da legislação, tendo os docentes o papel de definir com maior clareza os objetivos educacionais propostos e a instituição de promover a divulgação da legislação sobre avaliação.

description: Stakeholders make various types of decisions with respect to requirements, design, management, and so on during the software development life cycle. Nevertheless, these decisions are typically not well documented and classified due to limited human resources, time, and budget. To this end, automatic approaches provide a promising way. In this paper, we aimed at automatically classifying decisions into five types to help stakeholders better document and understand decisions. First, we collected a dataset from the Hibernate developer mailing list. We then experimented and evaluated 270 configurations regarding feature selection, feature extraction techniques, and machine learning classifiers to seek the best configuration for classifying decisions. Especially, we applied an ensemble learning method and constructed ensemble classifiers to compare the performance between ensemble classifiers and base classifiers. Our experiment results show that (1) feature selection can decently improve the classification results; (2) ensemble classifiers can outperform base classifiers provided that ensemble classifiers are well constructed; (3) BoW + 50% features selected by feature selection with an ensemble classifier that combines Naïve Bayes (NB), Logistic Regression (LR), and Support Vector Machine (SVM) achieves the best classification result (with a weighted precision of 0.750, a weighted recall of 0.739, and a weighted F1-score of 0.727) among all the configurations. Our work can benefit various types of stakeholders in software development through providing an automatic approach for effectively classifying decisions into specific types that are relevant to their interests.
