description: Edward Deng interviews his father, Kun Deng, about energy usage in his life, from his childhood in rural China in the 1960s to his career in the United States, as an investment professional on Wall Street. Deng discusses moving to the countryside at a young age, after his mother was sent there for reeducation as part of the Cultural Revolution. He describes differences between urban and rural living and remembers rationing resources like kerosene, collecting water from the village well, and having no electricity. Deng reflects on the relationships between community members, who he says shared with one another despite their own limited resources. Deng also discusses burning wood for cooking, which placed a strain on nearby forests and resulted in deforestation. Later, he says people began to burn sawdust. Deng also describes the differences he noticed in college, where running water and electricity were more accessible, and discusses the establishment of diplomatic relations between China and the United States in 1979. Deng says he was envious of American appliances and western luxuries. He also reflects on moving to the United States, cultural shifts in modern China, air pollution, and differences between his childhood in China and his son's childhood in the United States. Deng describes how his work in investment banking impacts his perspective on energy and offers predictions for the future of renewable energy and environmental, social, and governance (ESG) investing. Deng concludes by discussing the struggle between profit and social responsibility.
Re-entrant spin-flop transition in nanomagnets

description: Antiferromagnetic chains with an odd number of spins are known to undergo a transition from an antiparallel to a spin-flop configuration when subjected to an increasing magnetic field. We show that in the presence of an anisotropy favoring alignment perpendicular to the field, the spin-flop state appears for both weak and strong field, the antiparallel state appearing for intermediate fields. Both transitions are second order, the configuration varying continuously with the field intensity. Such re-entrant transition is robust with respect to quantum fluctuations and it might be observed in different types of nanomagnets.

Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: In this paper, we present multi parametric quadgraph equations which are consistent around the cube. These equations are obtained by applying a `double twist' to known integrable equations. Furthermore, we perform a limit to one of these equations to derive the non-symmetric equation which is given by Hietarinta and Viallet. As a result, we obtain a novel Lax pair of this equation.

description: Learning about databases is indispensable for individuals studying software engineering or computer science or those involved in the IT industry. We analyzed a remote educational escape room for teaching about databases in four different higher education courses in two consecutive academic years. We employed three instruments for evaluation: a pre- and post-test to assess the escape room's effectiveness for student learning, a questionnaire to gather students' perceptions, and a Web platform that unobtrusively records students' interactions and performance. We show novel evidence that educational escape rooms conducted remotely can be engaging as well as effective for teaching about databases.

Subjects: subject: policy brief
subject: STEM

description: The demand for graduates with Science Technology Engineering and Mathematics (STEM) degrees continues to rapidly increase.1 By 2018, the majority of positions that require a minimum of a bachelor degree will necessitate considerable mathematics and/or science training.2 In order for students to access, persist, and complete STEM majors, they must have a sufficient academic background to meet the demands of college STEM courses. The National Mathematics Advisory Panel recommends that students complete an authentic algebra course by grade 8 and have an understanding of Algebra II concepts by high school graduation.3 This investigation explored characteristics (e.g. grade Algebra 1 completed, gender, ethnicity, disability status, socio- economic status, district locality) that influence the likelihood of Texas students succeeding in advanced coursework in high school, gaining admission to college, and earning STEM degrees. Study findings suggest that several demographic factors influence the likelihood that students obtain admission to Texas public universities and complete STEM degrees. Texas is committed to improving college readiness and completion.4 However, there is a rich body of research suggesting that demographic barriers may prevent access, persistence, and completion of college, especially for students of color, students with disabilities, and students from low socio-economic backgrounds.5 This project aimed to develop an understanding of student and school characteristics (i.e., grade Algebra 1 completed, gender, ethnicity, disability status, socio-economic status, rural, suburban, urban school location) that influence the likelihood that Texas students succeed in advanced coursework in high school, enter college, and obtain STEM degrees. If predictors of success in STEM fields are identified, policies can be adjusted to address the needs of Texas students.

description: Lags measured from correlated X-ray/UV/optical monitoring of AGN allow us to determine whether UV/optical variability is driven by reprocessing of X-rays or X-ray variability is driven by UV/optical seed photon variations. We present the results of the largest study to date of the relationship between the X-ray, UV and optical variability in an AGN with 554 observations, over a 750d period, of the Seyfert 1 galaxy NGC 5548 with Swift. There is a good overall correlation between the X-ray and UV/optical bands, particularly on short timescales (tens of days). These bands lag the X-ray band with lags which are proportional to wavelength to the power 1.23+/-0.31. This power is very close to the power (4/3) expected if short timescale UV/optical variability is driven by reprocessing of X-rays by a surrounding accretion disc. The observed lags, however, are longer than expected from a standard Shakura-Sunyaev accretion disc with X-ray heating, given the currently accepted black hole mass and accretion rate values, but can be explained with a slightly larger mass and accretion rate, and a generally hotter disc. Some long term UV/optical variations are not paralleled exactly in the X-rays, suggesting an additional component to the UV/optical variability arising perhaps from accretion rate perturbations propagating inwards through the disc.

description: To enhance the understanding of air quality within underground railway stations (URS), a methodology has been developed to establish a baseline profile of particle concentrations (PM10 and PM2.5). This approach incorporates an extensive data cleaning process based on the identification of URS operation periods, physically inconsistent or mathematically aberrant data, and comparing the profile of each day to an average profile. The versatility of this methodology allows its application to different particle classes within various URS. The results obtained from the three studied URS indicate the possibility of obtaining reliable daily typical profiles even over short measurement periods (up to one or two weeks).

MDFRC item.

The role of flow and floodplains for the recruitment of fishes in the Murray-Darling Basin, Australia, remains a contentious issue. In this context, the reproductive ecology of golden perch Macquaria ambigua, a widespread, high-profile angling species with a propensity to produce large numbers of semi-pelagic eggs remains to be resolved. Back-calculation of spawning dates from otoliths of juvenile golden perch (Macquaria ambigua) collected in August and November 1997 from the Menindee Lakes on the floodplain of the Darling River, in western New South Wales, Australia, advances understanding of spawning of this species in three ways: (1) golden perch spawned at lower temperatures (<= 18.8 degrees C) than has previously been reported from the Murray-Darling Basin; (2) golden perch in the Menindee Lakes can be derived from spawning in all seasons of the year in contrast to what is apparent in more southerly locations of the Murray-Darling Basin; and (3) spawning can occur in the absence of floods.

description: Liquid-liquid equilibrium (LLE) phase diagrams have been determined, by means of the critical opalescence method with a laser scattering technique, for the mixtures 4-phenylbutan-2-one + CH$_3$(CH$_2$)$_n$CH$_3$ ($n = 10,12,14$) and for benzyl ethanoate + CH$_3$(CH$_2$)$_n$CH$_3$ ($n = 12,14$). The systems are characterized by having an upper critical solution temperature (UCST), which increases with n. The corresponding LLE curves show a rather horizontal top and become skewed toward higher mole fractions of the polar compound when n is increased. Calorimetric and LLE measurements show that, for mixtures with molecules with a given functional group, interactions between aromatic molecules are stronger than those between homomorphic linear molecules (aromaticity effect). This has been ascribed to proximity effects arising from the presence of the polar group and the aromatic ring within the same molecule. Proximity effects become weaker in the sequence 1-phenylpropan-2-one > 4-phenylbutan-2-one > 1-phenylethanone and are more important in benzyl ethanoate than in ethyl benzoate molecules. Values of the critical compositions and temperatures calculated with the DISQUAC group contribution model are in good agreement with the experimental results. Accordingly, the shape of the LLE curves is also correctly described by DISQUAC.

description: Ellerman bombs (EBs) are short-lived and compact structures that are observed well in the wings of the hydrogen H-alpha line. EBs are also observed in the chromospheric CaII lines and in UV continua. H-alpha line profiles of EBs show a deep absorption at the line center and enhanced emission in the line wings. Similar shapes of the line profiles are observed for the CaII IR line at 8542 ang. It is generally accepted that EBs may be considered as compact microflares located in lower solar atmosphere. However, it is still not clear where exactly the emission of EBs is formed in the solar atmosphere. High-resolution spectrophotometric observations of EBs were used for determining of their physical parameters and construction of semi-empirical models. In our analysis we used observations of EBs obtained in the H-alpha and CaII H lines. We also used NLTE numerical codes for the construction of grids of 243 semi-empirical models simulating EBs structures. In this way, the observed emission could be compared with the calculated line spectra. For a specific model we found reasonable agreement between the observed and theoretical emission and thus we consider such model as a good approximation of the EBs atmospheres. This model is characterized by an enhanced temperature in the lower chromosphere and can be considered as a compact structure (hot spot). For the first time the set of two lines H-alpha and CaII H was used to construct semi-empirical models of EBs. Our analysis shows that EBs can be described by a "hot spot" model, with the temperature and/or density increase through a few hundred km atmospheric structure. We confirmed that EBs are located close to the temperature minimum or in the lower chromosphere. Two spectral features, observed simultaneously, significantly strengthen the constraints on a realistic model.

description: Alkali doped aromatic compounds have shown evidence of metallic and superconducting phases whose precise nature is still mysterious. In potassium and rubidium doped phenanthrene, superconducting temperatures around 5 K have been detected, but such basic elements as the stoichiometry, crystal structure, and electronic bands are still speculative. We seek to predict the crystal structure of M3-phenanthrene (M = K, Rb) using ab-initio evolutionary simulation in conjunction with density functional theory (DFT), and find metal but also insulator phases with distinct structures. The original P21 herringbone structure of the pristine molecular crystal is generally abandoned in favor of different packing and chemical motifs. The metallic phases are frankly ionic with three electrons acquired by each molecule. In the nonmagnetic insulating phases the alkalis coalesce reducing the donated charge from three to two per phenanthrene molecule. A similar search for K3-picene yields an old and a new structure, with unlike potassium positions and different electronic bands, but both metallic retaining the face-to-edge herringbone structure and the P21 symmetry of pristine picene. Both the new K3-picene and the best metallic M3-phenanthrene are further found to undergo a spontaneous transition from metal to antiferromagnetic insulator when spin polarization is allowed, a transition which is not necessarily real, but which underlines the necessity to include correlations beyond DFT. Features of the metallic phases that may be relevant to phonon-driven superconductivity are underlined.

description: Russian Internet Trolls use fake personas to spread disinformation through multiple social media streams. Given the increased frequency of this threat across social media platforms, understanding those operations is paramount in combating their influence. Using Twitter content identified as part of the Russian influence network, we created a predictive model to map the network operations. We classify accounts type based on their authenticity function for a sub-sample of accounts by introducing logical categories and training a predictive model to identify similar behavior patterns across the network. Our model attains 88% prediction accuracy for the test set. Validation is done by comparing the similarities with the 3 million Russian troll tweets dataset. The result indicates a 90.7% similarity between the two datasets. Furthermore, we compare our model predictions on a Russian tweets dataset, and the results state that there is 90.5% correspondence between the predictions and the actual categories. The prediction and validation results suggest that our predictive model can assist with mapping the actors in such networks.

description: La logistica si è recentemente imposta come una prospettiva privilegiata per la comprensione del mondo contemporaneo a partire dall’interazione tra mobilità multiple – di persone, merci, capitali, informazioni. Tuttavia, questa prospettiva rischia di risolvere nel presente dinamiche che sono ricorse storicamente in modali-tà diverse, non lineari e reversibili. I contributi di questo volume si pongono l’obiettivo di mettere in evidenza le specificità storiche e geografiche dei processi logistici. Essi contribuiscono alla definizione di una “logistica delle migrazioni” a partire da casi di studio specifici, proponendo al tempo stesso alcuni elementi utili a problematizzare continuità e rotture storiche all’interno di un confronto tra scien-ze storiche e scienze politico-sociali.

description: Johann Adolph Scheibes viel zitierte Bach-Kritik Bach aus dem Jahr 1737 richtet sich gegen Bachs Vokalmusik, auch wenn Scheibe dies nicht ausdrücklich erklärt. Bachs komplexe Kompositionsweise entsprach nicht den ästhetischen Anforderungenseiner Zeit an eine einfache, empfindsame oder erhabene Vokalmusik. Bachs Vokalwerke waren jedenfalls nicht in dem Maße in der Lage, diese Anforderungen zu erfüllen, wie die Werke von Händel, Hasse oder Graun. (Übertragung des englischen Resümees am Ende des Bandes)
