description: A new eusdesmane sesquiterpenoid, characterised as 5-acetoxy-9aβ-hydroxy-4aαH-3,5α, 8aβ-trimethyl-4, 4a, 6, 7, 8a, 9-hexahydronaphtho-([2, 3 b]-dihydrofuran-2-one)-8-one or phaeusmane F acetate (1) has been isolated from the rhizomes of the South African variety of wild ginger (iphonochilus aethiopicus (Schweinf) B.L. Burtt). The compound was obtained after a series of column and gel filtration chromatography. Its structure was elucidated by NMR and Mass-Spectrometric analyses, including 1 D-, 2 D-NMR and HR-LCMS. This is an initial report of the compound from a Siphonochilus sp. Previously isolated similar compounds from the plant material were 4aαH-3,5α,8aβ-trimethyl-4,4a,8a,9-tetrahydronaphtho[2,3b]-furan-8-one (siphonochilone) (2), 9aβ-hydroxy-4aαH-3,5α,8aβ-trimethyl-4,4a,8a,9-tetrahydronaphtho-([2,3b]-dihydrofuran-2-one)-8-one (3), 4aαH-3,5α,8aβ-trimethyl-4,4a,8a,9-tetrahydronaphtho-([2,3b]-dihydrofuran-2-one)-8-one (4), 2-hydroxy-4aαH-3,5α,8aβ-trimethyl-4,4a,8a,9-tetrahydro-naphtho[2,3b]- furan-8(5H)-one (5), 4aαH-3,5α,8aβ-trimethyl-4,4a,8a-trihydronaphtho-([2,3b]-dihydrofuran-2-one)-8-one (6).
Investors versus Workers: A Class‐Based Critique of International Investment Treaties

description: Bilateral investment treaties constitute an important instrument to facilitate global investment. Recent discussions in political theory have highlighted several normative concerns raised by bilateral investment treaties. One worry is that investment treaties undermine national self-determination as they grant investors far-reaching protections that can be legally enforced. Another worry is that the benefits and burdens entailed in bilateral investment treaties are distributed unfairly in a way that benefits investors at the expense of states and disadvantaged groups within states. Instead of critiquing bilateral investment treaties from a perspective of global (distributive) justice, in this article I develop a class-based critique. This involves a twofold departure. First, the article shifts the focus from distributions to the power relations that are built into the global capitalist economy and that come into sharp relief in the practice of global investment. Second, rather than focusing on the relation between states and investors, I claim that in a class-based critique the relation between workers and investors should take centre stage. I argue that bilateral investment treaties are effectively an instrument of class domination, insofar as they reproduce and increase the power of transnational corporations while at the same time decreasing the power of workers.

description: This paper analyzes the tweeting behavior of 37 astrophysicists on Twitter and compares their tweeting behavior with their publication behavior and citation impact to show whether they tweet research-related topics or not. Astrophysicists on Twitter are selected to compare their tweets with their publications from Web of Science. Different user groups are identified based on tweeting and publication frequency. A moderate negative correlation (p=-0.390*) is found between the number of publications and tweets per day, while retweet and citation rates do not correlate. The similarity between tweets and abstracts is very low (cos=0.081). User groups show different tweeting behavior such as retweeting and including hashtags, usernames and URLs. The study is limited in terms of the small set of astrophysicists. Results are not necessarily representative of the entire astrophysicist community on Twitter and they most certainly do not apply to scientists in general. Future research should apply the methods to a larger set of researchers and other scientific disciplines. To a certain extent, this study helps to understand how researchers use Twitter. The results hint at the fact that impact on Twitter can neither be equated with nor replace traditional research impact metrics. However, tweets and other so-called altmetrics might be able to reflect other impact of scientists such as public outreach and science communication. To the best of our knowledge, this is the first in-depth study comparing researchers' tweeting activity and behavior with scientific publication output in terms of quantity, content and impact.

description: The polar fraction of the MeOH extract of the roots of Corrigiola litoralis subsp. telephiifolia (Pourr.) Briq. (Caryophyllaceae) was investigated for its constituents and two previously unreported monodesmosides triterpene saponins, telephiifoliosides A and B (1 and 2), along with the known bonushenricoside A (3) were isolated. Their structures were elucidated by combined spectroscopic and spectrometric techniques (1H NMR, 13C NMR, HSQC, 1H-1H COSY, HMBC, TOCSY, NOESY, HRESIMS) and chemical methods. The structures of the new saponins were established as; 3-O-α-L-arabinopyranosyljaligonic acid (1), and 3-O-α-L-arabinopyranosylphytolaccagenin ester (2). Upon evaluation of the antiproliferative activity on human malignant epithelial (HeLa) cells, none of the isolated compounds was efficient at the concentration of 33 µM.

description: Up to now, jet kinematic studies of radio quasars have barely reached beyond the redshift range at $z>3.5$. This significantly limits our knowledge of high-redshift jets, which can provide key information for understanding the jet nature and the growth of the black holes in the early Universe. In this paper, we selected 9 radio-loud quasars at $z>3.5$ which display milliarcsec-scale jet morphology. We provided evidence on the source nature by presenting high-resolution very long baseline interferometry (VLBI) images of the sample at 8.4~GHz frequency and making spectral index maps. We also consider Gaia optical positions that are available for 7 out of the 9 quasars, for a better identification of the jet components within the radio structures. We find that 6 sources can be classified as core--jet blazars. The remaining 3 objects are more likely young, jetted radio sources, compact symmetric objects. By including multi-epoch archival VLBI data, we also obtained jet component proper motions of the sample and estimated the jet kinematic and geometric parameters (Doppler factor, Lorentz factor, viewing angle). Our results show that at $z>3.5$, the jet apparent transverse speeds do not exceed 20 times the speed of light ($c$). This is consistent with earlier high-redshift quasar measurements in the literature and the tendency derived from low-redshift blazars that fast jet speeds ($>40\,c$) only occur at low redshifts. The results from this paper contribute to the understanding of the cosmological evolution of radio AGN.

Systematic Law for Half-lives of Double $β$-decay with Two Neutrinos

description: Nuclear double $β$-decay with two neutrinos is a rare and important process for natural radioactivity of unstable nuclei. The experimental data of nuclear double $β^{-}$-decay with two neutrinos are analyzed and a systematic law to calculate the half-lives of this rare process is proposed. It is the first analytical and simple formula for double $β$-decay half-lives where the leading effect from both the Coulomb potential and nuclear structure is included. The systematic law shows that the logarithms of the half-lives are inversely proportional to the decay energies for the ground state transitions between parent nuclei and daughter nuclei. The calculated half-lives are in agreement with the experimental data of all known eleven nuclei with an average factor of 3.06. The half-lives of other possible double $β$-decay candidates with two neutrinos are predicted and these can be useful for future experiments. The law, without introducing any extra adjustment, is also generalized to the calculations of double $β$-decay half-lives from the ground states of parent nuclei to the first $0^+$ excited states of daughter nuclei and the calculated half-lives agree very well with the available data. Some calculated half-lives are the first theoretical results of double $β$-decay half-lives from the ground states of parent nuclei to the first $0^+$ excited states of daughter nuclei. The similarity and difference between the law of $α$-decay and that of double $β^{-}$-decay are also analyzed and discussed.

Colloquium: Time-reversal violation with quantum-entangled B mesons

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Symmetry transformations have been proven a bedrock tool for understanding the nature of particle interactions, formulating and testing fundamental theories. Based on the up to now unbroken CPT symmetry, the violation of the CP symmetry between matter and antimatter by weak interactions, discovered in the decay of kaons in 1964 and observed more recently in 2001 in B mesons, strongly suggests that the behavior of these particles under weak interactions must also be asymmetric under time reversal T. However, until the recent years there has not been a direct detection of the expected time-reversal violation in the time evolution of any system. This Colloquium examines the field of time-reversal symmetry breaking in the fundamental laws of physics. For transitions, its observation requires an asymmetry with exchange of initial and final states. We discuss the conceptual basis for such an exchange with unstable particles, using the quantum properties of Einstein Podolsky-Rosen (EPR) entanglement available at B meson factories combined with the decay as a filtering measurement. The method allows a clear-cut separation of different transitions between flavor and CP eigenstates in the decay of neutral B mesons. These ideas have been implemented for the experiment by the BaBar Collaboration at SLAC's B factory. The results, presented in 2012, prove beyond any doubt the violation of time-reversal invariance in the time evolution between these two states of the neutral B meson.

description: Chemical investigation of the deep-sea-derived fungus Aspergillus sydowii MCCC 3A00324 led to the isolation of one new acremolin type alkaloid (acremolin D, 1) and five known alkaloids (2‒6). The planar structure of 1 was established by the extensive analyses of the NMR and HRESIMS data, while its absolute configuration was assigned by the comparison of the experimental and calculated ECD data. Acremolin D (1) represented the second analogue of acremolin found in nature. All compounds were evaluated for their cytotoxic activities against six human cancer cell lines (A549, Hela-S3, MCF-7, HepG2, K562, and SF-268). As a result, compounds 1 and 2 exhibited a certain inhibitory effects against the proliferation of the A549, Hela-S3, HepG2, and K562 cell lines at the concentration of 20 µM.
A generous helping? The archaeology of soup kitchens and their role in post-medieval philanthropy 1790-1914
Creators: name: Carstairs, Philip J.
Publisher: name: University of Leicester
Year: 2022

description: Soup kitchens, the charitable provision of food, principally soup (often accompanied by bread), became widespread in late-eighteenth century Britain. They were not a British invention. Soup is an ancient means of relieving hunger, but the circumstances during the Napoleonic Wars and their aftermath helped form a new type of institution which has been exported worldwide as a panacea for the pangs of hunger fostered by urbanisation and industrialisation. This thesis traces the development of this novel institution and its material culture in England. It examines the changing nature of charity and the relationship between the poor and the better off in five counties, Northumberland, Kent, Staffordshire, Hertfordshire and Buckinghamshire, within a national context. As historical archaeology, this research is inevitably cross-disciplinary, drawing on a wide range of evidence. Archival sources for soup kitchens are sparse, but nineteenth-century local newspapers provide a rich albeit fragmentary record with which to create the background for interpreting the material culture, architecture and landscapes of charity. Objects, structures, landscapes and patterns of behaviour shaped the performance of charity, which is interpreted through architectural and spatial analysis and the lived-experience of the participants. This study takes the existing research on institutions in new directions and challenges our concepts of what archaeological sites are. By bringing both material evidence and innovative methodologies to the study of poverty and charity, the thesis contributes to the understanding of the makeshift economy that the poor used to survive. Soup kitchens were widespread during the long nineteenth century, feeding between 10 and 30% of the population during wintertime. Later, soup kitchens fell from grace, particularly in industrial areas and were blamed for creating the problems they sought to alleviate. In less industrial areas soup remained in the repertoire of acceptable charity. England had developed very different regional cultures of charity.

Nosso objetivo é pesquisar a origem do repertório de câmara brasileiro para quartetos e conjuntos de saxofones, nos séculos XX e XXI, a partir de uma abordagem histórica e interpretativa para a performance em grupo. A pesquisa documental iniciou-se, no ano de 2018, em dois acervos da cidade do Rio de Janeiro: o Acervo Musical da Banda do Corpo de Bombeiros e o Acervo de Manuscritos Musicais da Biblioteca Alberto Nepomuceno da Escola de Música da UFRJ. No primeiro acervo, as partituras não se encontram catalogadas, dificultando assim, o acesso às fontes. Além disso, alguns desses manuscritos musicais estão em fase de degradação e não receberam o tratamento adequado de conservação ao longo dos anos, ou seja, alguns deles podem sumir a qualquer momento. De acordo com Castagna e Duarte (2019), “existe a necessidade de consciência metodológica para a pesquisa e exercício da gestão de acervos musicais, além de sua consulta, uma vez que esse tipo de gestão proporciona a salvaguarda e acesso a quantidades cada vez maiores de usuários”. A partir do cotejamento as fontes (partituras, bibliografias, catálogos, por exemplo) foram possíveis resgatar informações históricas relevantes sobre uma prática musical vigente no início do século XX, quando o repertório de câmara para conjuntos de saxofones ainda era constituído em sua maior parte por transcrições de óperas, como é o caso do Noturno, da ópera Condor de Carlos Gomes (transcrição realizada por Francisco Braga, em julho de 1928). Resgatamos, ainda, as versões para octeto/noneto de saxofones das obras Cantigas e Danças dos Pretos e Gavião de Penacho do melodrama d’O Contratador de Diamantes (com texto de Afonso Arinos, 1905) que podem ser as primeiras peças escritas para essa formação de câmara no Brasil. Dessa forma, Braga teria sido o pioneiro na formação deste repertório contribuindo assim para a consolidação dos primeiros conjuntos de saxofones durante o período da Belle-Époque (1889-1930).

description: Machine learning (ML) approaches enable large-scale atomistic simulations with near-quantum-mechanical accuracy. With the growing availability of these methods there arises a need for careful validation, particularly for physically agnostic models - that is, for potentials which extract the nature of atomic interactions from reference data. Here, we review the basic principles behind ML potentials and their validation for atomic-scale materials modeling. We discuss best practice in defining error metrics based on numerical performance as well as physically guided validation. We give specific recommendations that we hope will be useful for the wider community, including those researchers who intend to use ML potentials for materials "off the shelf".

description: La finalità precipua della ricerca teorica in pedagogia è duplice: da un lato lo studio della prassi al fine di migliorare la funzione educativa sul campo, dall’altro lo sviluppo di una ricerca teoretica che costruisca un pensiero pedagogico speculativamente puro intorno all’educazione/educabilità umana. Lungo un continuum e in un rapporto di complementarietà di colloca la ricerca applicata la quale tende a verificare ipotesi di soluzione di problemi concreti. Lo stretto nesso tra teoria e prassi si realizza nel passaggio che la pedagogia attua nel sottoporre i modelli teorici di tipo ipotetico deduttivo alla verifica empirica. In pedagogia si può parlare di teorie scientifiche quando si ha a che fare con sistemi articolati di idee che fanno da scheletro al corpo di tale disciplina. Il fine di tali sistemi è di gettare luce sulle realtà della prassi, indagate attraverso ipotesi conoscitive che possono diventare prassi sia per via sperimentale sia per via speculativa. I sistemi di saperi che fanno della pedagogia una scienza teorica, pratica, metateoretica e teoretica, studiano l’educazione in quanto processo, percorso, relazione, strumento e fine, sistema e libertà, materialità e spiritualità, natura e cultura. ..

description: The main aim of theoretical research in education is twofold: on the one hand, the study of practice in order to improve the educational function on the field, on the other hand the development of a theoretical research that constructs a pedagogical thinking speculatively pure around education/ human educability. Along a continuum and in a complementary relationship ranks applied research which tends to check possible solutions to concrete problems. The close link between theory and practice is realized in the passage that implements the pedagogy of subjecting the theoretical models of hypothetical deductive to empirical verification. In pedagogy we can talk about scientific theory when it has to do with articulated systems of ideas that form the skeleton of the discipline. The aim of such systems is to shed light on the realities of practice, investigated through hypothesis that can become practice both experimentally as well as by speculative. The systems of knowledge of pedagogy that make it a theoretical science, practice, metatheoretical and theoretical, study education as a process, route, relationship, instrument and order, system, and freedom, materiality and spirituality, nature and culture. ..

description: Cuba’s rich musical legacy has been one of the island’s most important national and international contributions for over 100 years. Since the end of 2011, Cuba has undergone the most significant socioeconomic changes since its 1959 Socialist Revolution. These include the introduction of private property, launch and growth in internet access, and a significant increase in travel from and to the island. As a result, the country entered a new phase in its music production and scholarship, altering Havana’s music scene, profession and the geographies of Cuban music. A key location in Cuba's music scene is "the street", regarded as the home of music, and where both Cubans and visitors have their first encounters with music on the island. Following the new socioeconomic adjustments on the island, the streets of Havana are transforming, and so is their relationship to Cuban music and musicians. The street is a physical locale and an abstract imaginary where music is created, produced and performed, and its image is circulated both on the island and abroad. I argue that with the introduction of private property ownership to the island and the proliferation of privately-owned music venues across Havana, the role of the street as the home of Cuban music has been reconfigured from an actual locale to an imaginary where musicians are searching for identity and authenticity in a rapidly commercialising world. Streets are converted from the site where any underprivileged Afro-Cuban child can learn to play and perform music to world-class standards to the home of five-star hotels, exclusive shopping malls and Chanel’s seasonal catwalk. I further investigate how this image of “the street” as the home of Cuban music continues to infuse contemporary songs through images and lyrics, and is internationally exported, creating a distorted image of Havana’s music scene abroad.

description: We prove that the empirical density of states of quantum spin glasses on arbitrary graphs converges to a normal distribution as long as the maximal degree is negligible compared with the total number of edges. This extends the recent results of [6] that were proved for graphs with bounded chromatic number and with symmetric coupling distribution. Furthermore, we generalise the result to arbitrary hypergraphs. We test the optimality of our condition on the maximal degree for $p$-uniform hypergraphs that correspond to $p$-spin glass Hamiltonians acting on $n$ distinguishable spin-$1/2$ particles. At the critical threshold $p=n^{1/2}$ we find a sharp classical-quantum phase transition between the normal distribution and the Wigner semicircle law. The former is characteristic to classical systems with commuting variables, while the latter is a signature of noncommutative random matrix theory.

description: The Collective Perception Service (CPS) enables the enhancement of environmental awareness of Intelligent Transport System Stations (ITS-S) through the exchange of tracking information between stations. As the market penetration of CPS is growing, the intelligent distribution of the limited communication resources becomes more and more challenging. To address this problem, the ETSI CPS proposes dynamic-based object selection to generate Collective Perception Messages. However, this approach has limits and barely considers detection accuracy and the recent information available at other ITS-Ss in the transmission range. We show a proposal considering the current object tracking accuracy in the local environment and the object tracking from messages received by other stations in order to intelligently decide whether to include an object in a CPM. The algorithm decides based on the relative entropy between the local and V2X tracking accuracy if the object information is valuable for the nearby stations. Our simulation according to the ITS-G5 standard shows that the Channel Busy Ratio (CBR) can be reduced with accuracy-based generation of CPM while improving Object Tracking Accuracy (OTA) compared to generation based on ETSI rules.

Popular Music in a colonial city: musicians’ experiences and socio-racial issues in Lourenço Marques (1960-75)

description: Lourenço Marques, nowadays known as Maputo, was the main city in Mozambique, a territory which was under Portuguese colonial rule until 1975. As a result of the urban planning promoted by the Portuguese colonial administration, social inequalities of the colonial system were inscribed in the urban geography of Lourenço Marques. There was the city centre, known as the “city of cement”, a place mainly occupied by European white population from the middle/upper classes; outside there was an extended area of neighbourhoods with poor living conditions, mainly inhabited by African population and by a smaller part of low-class Europeans and immigrants. This had an important impact on the social life of the city, reinforcing structural inequalities of the colonial system and promoting dynamics of spatial segregation, racial discrimination and creating more obstacles for those who had precarious positions in the city. In recent years, some studies have been focusing on the relation between cultural expressions and social processes in the urban context of Lourenço Marques – for example, the case of football (Domingos, 2012). Music was an activity with particular relevance in that context, since Lourenço Marques was a city with an intense nightlife activity, in which popular music had a notorious presence. There are already important accounts about music and the colonial context of Mozambique (Freitas, 2018; Lichuge, 2017; Filipe, 2012; Carvalho, 1997). However, the articulation between the activities of popular music groups from different areas of Lourenço Marques and the social dynamics in the city is a topic that still has a lot to explore. Its analysis can demonstrate the ambivalence felt by the individuals involved, but also the way they managed to overcome the constraints of the colonial system. With the main focus on the period between 1960 and 1975, marked by the historical processes of late colonialism (Castelo et al., 2012) this work approaches musical activities as a way to understand social and racial distinctions in a colonial city, based on ethnographic interviews.

description: Polarisation measurements of pulsars offer an unique insight into the geometry of the emission regions in the neutron star magnetosphere. Therefore, they provide observational constraints on the different models proposed for the pulsar emission mechanisms. Optical polarisation data of the Vela pulsar was obtained from the {\em Hubble Space Telescope} ({\em HST}) archive. The data, obtained in two filters (F606W; central wavelength = 590.70 nm, and F550M; central wavelength = 558.15 nm), consists of a series of observations of the pulsar taken with the {\em HST}/Advanced Camera for Surveys (ACS) and covers a time span of 5 days. This data have been used to carry out the first high-spatial resolution and multi-epoch study of the polarisation of the pulsar. We produced polarisation vector maps of the region surrounding the pulsar and measured the degree of linear polarisation (P.D.) and the position angle (P.A.) of the pulsar's integrated pulse beam. %This yielded We obtained $\rm P.D.=8.1\%\pm0.7\%$ and $\rm P.A.=146.3\degr\pm2.4\degr$, averaged over the time span covered by these observations. These results not only confirm those originally obtained by \citeauthor{Wagner00} and \citeauthor{Mignani07}, both using the Very Large Telescope (VLT), but are of greater precision. Furthermore, we confirm that the P.A. of the pulsar polarisation vector is aligned with the direction of the pulsar proper-motion. The pulsar wind nebula (PWN) is undetected in polarised light as is the case in unpolarised light, down to a flux limit of 26.8 magnitudes arcsec$^{-2}$.
