Teaching Oedipus Tyrannos with a rich digital edition, in a pandemic
Creators: name: Blackwell, Christopher
name: Mambrini, Francesco
Publisher: name: FuturoClassico FCl
Year: 2022
Subjects: Digital editions; pedagogy; treebanks; CITE architecture; Greek tragedy.

description: The article presents a digital scholarly edition of Sophocles’ Oedipus Tyrannos that was used as support for an undergraduate seminar in Ancient Greek at Furman University. Our edition is a series of HTML pages, built programmatically, integrating syntactic, morphological, and lexical data. The edition is based on two of the most important acquisitions in the last decade of research in the Digital Classics: the CITE/CTS architecture and the treebanks of Ancient Greek. Our approach aims to overcome both the technical and linguistic “friction” that hinders the process of reading ancient texts in their original, unabridged format. While our work on the notion of a “zero-friction edition” predates the spread of COVID-19, all the problems that we were trying to tackle dramatically came into prominence with the outbreak of the pandemic during the Spring Semester of 2020. We discuss the outcomes and lessons-learned from this pedagogical experience.

Changing the Mask: Formative Teaching of Ancient Greek Theatre in the Digital Age
Creators: name: Blankenborg, Ronald

Year: 2022
Subjects: Formative assessment; teaching ancient drama; covid-19; digital humanities; feedback literacy.

description: Given the special circumstances during a pandemic, and the continuing need to keep improving the quality of teaching through suitable didactic strategies, this paper argues for a further development of the formative approach of teach­ing in order to make accessible the full repertory of online available resources. For the study of ancient Greek theatre, due to its strong ties with the ‘visual-based’ Reception, Cultural and Performance Studies, the formative approach is especially well suited. Formative assessment’s main objective is to contribute to the learning process through feedback and criticism. The unlimited availability of study material, and the possibility (and challenge) of contributing to this material through peer-to-peer feedback and participa­tion in work-in-progress, are opportunities that the digital age offers, and have not been on offer on such scale before. The study of classics rapidly develops into students’ participation, criticism, and contribution through the wealth of online initiatives and projects concerning lexica, editions of texts, fragments, and commentaries, and the archiving and reworking of reception pieces. In online teaching, digital philology has become a students’ assignment too. Formative assessment encourages students to ‘learn-through-participation’ and immersion.

Subjects: Domain-Specific Languages; textual annotation; Ancient Greek Tragedy.

description: This article illustrates Euporia, i.e. a method for annotating literary texts based on Domain-Specific Languages. The annotation systems developed using this method are modeled on the needs of the users, their specific habits of studying and annotating texts, and the aims of their research. The two case studies discussed in this contribution show the application of the method in the context of two projects focused on the texts of Greek tragedy: on the one hand, a didactic project based on Aeschylus’ Persians, on the other hand, a research project in the field of anthropology of the ancient world, based on the entire corpus of the Greek tragedy. The discussion aims to illustrate how text annotation through DSL can have both a didactic function and a scientific interest.

description: We investigate a model where the dark matter particle is a chiral fermion field charged under a global $U(1)$ symmetry which is assumed to be spontaneously broken, leading to a pseudo-Goldstone boson (PGB). We argue that the dark matter annihilation into PGBs determine the dark matter relic abundance. Besides, we also note that experimental searches for PGBs allow either for a very long lived PGB, with a lifetime much longer than the age of the Universe, or a relatively short lived PGB, with a lifetime shorter than one minute. Hence, two different scenarios arise, producing very different signatures. In the long lived PGB scenario, the PGB might contribute significantly to the radiation energy density of the Universe. On the other hand, in the short lived PGB scenario, and since the decay length is shorter than one parsec, the s-wave annihilation into a PGB and a $CP$ even dark scalar in the Galactic center might lead to an intense box feature in the gamma-ray energy spectrum, provided the PGB decay branching ratio into two photons is sizable. We also analyze the constraints on these two scenarios from thermal production, the Higgs invisible decay width and direct dark matter searches.

description: Massive and intermediate-mass stars reside in binary systems much more frequently than low-mass stars. Binaries containing massive main-sequence (MS) component(s) are often characterised by eccentric orbits, and can be observed as eccentric ellipsoidal variables (EEVs). The orbital phase-dependent tidal potential acting on the components of EEV can induce tidally excited oscillations (TEOs). We investigate how the history of resonances between the eigenmode spectra of the EEV components and the tidal forcing frequencies depends on the initial parameters of the system. We synthesised 20,000 evolutionary models of the EEVs across the MS. Later, we calculated the eigenfrequencies for each model. We focused only on the $l=2$, $m=0,+2$ modes. Knowing the temporal changes in the orbital parameters of simulated EEVs and the changes of the eigenfrequency spectra for both components, we were able to determine so-called `resonance curves', which describe the overall chance of a resonance occurring. We analysed the resonance curves by constructing basic statistics for them and analysing their morphology using machine learning methods, including the Uniform Manifold Approximation and Projection tool. The EEV resonance curves from our sample are characterised by striking diversity, including the occurrence of exceptionally long resonances or the absence of resonances for long evolutionary times. Both components may be subject to increased resonance rates as they approach the TAMS. On average, we should observe TEOs more frequently in EEVs containing massive components than intermediate-mass ones. TEOs will be particularly well-pronounced for EEVs with the component(s) close to the TAMS. Given the total number of resonances and their rates, TEOs may play an important role in the transport of angular momentum within massive and intermediate-mass stars (mainly near TAMS).

title: Pauschalrückstellungen im Unternehmens- und Steuerrecht
Creators: name: Schaler, Felix Valentin
Year: 2023

description: Spätestens mit der Kodifizierung des Grundsatzes der verlässlichen Schätzung in § 201 Abs 2 Z 7 UGB durch das RÄG 2014 hat die Diskussion über die steuerliche Zulässigkeit von Pauschalrückstellungen wieder an Fahrt aufgenommen. Unternehmensrechtlich hatte das RÄG zwar keine Änderungen zur Folge, es legte aber den Grundstein für das COVID-19-StMG durch das steuerliche Pauschalrückstellungen wieder zulässig wurden, nachdem sie mit dem StRfG 1993 untersagt worden waren. Unternehmensrechtlich war die Bildung von Pauschalrückstellungen unabhängig vom Steuerrecht immer möglich. Deren Ansatz in der UGB-Bilanz führte bei § 5 EStG Gewinnermittlern aber aufgrund des Verbots deren steuerlicher Bildung, in § 9 Abs 3 EStG idF vor dem COVID-19-StMG zwingend zu einer Durchbrechung des Maßgeblichkeitsprinzips. Sowohl unternehmens-, als auch steuerrechtlich ist für Pauschalrückstellungen darauf zu achten, dass diese dem Grundsatz der verlässlichen Schätzung entsprechend auf einer umsichtigen Beurteilung beruhen und bei Vorliegen der Voraussetzungen unter Berücksichtigung statistischer Erfahrungswerte zu bilden sind. Der wesentliche Unterschied zwischen Einzel- und Pauschalrückstellungen liegt darin, dass zweitere dem Grunde nach lediglich nach Erfahrungswerten gebildet werden und nicht aufgrund konkreter Umstände im Einzelfall, weshalb Pauschalrückstellungen auch vorrangig für Gewährleistungs-, Garantie- oder Produkthaftungsrückstellungen in der Massenproduktion eingesetzt werden. Folglich ist der Eintritt einer bestimmten Verbindlichkeit für die Bildung einer Einzelrückstellung noch nicht wahrscheinlich beziehungsweise konkretisiert genug, aber es kann bei Vorliegen vieler gleicher Geschäftsfälle mit entsprechender Sicherheit, unter Verwendung statistischer Methoden und Erfahrungswerte, festgestellt werden ob, und in welcher Höhe Rückstellungen zu bilden sind. Die vom Gesetzgeber durch die Änderung angestrebte weitere Vereinheitlichung von UGB-Bilanz und Steuerbilanz ist grundsätzlich gelungen. Einzig die steuerlichen Sondervorschriften zur Abzinsung von Rückstellungen mit einer Restlaufzeit von mehr als einem Jahr führen noch zu einer Mehr-Weniger-Rechnung.

description: We present a multi-wavelength analysis of the galaxy cluster SPT-CL J0607-4448 (SPT0607), which is one of the most distant clusters discovered by the South Pole Telescope (SPT) at $z=1.4010\pm0.0028$. The high-redshift cluster shows clear signs of being relaxed with well-regulated feedback from the active galactic nucleus (AGN) in the brightest cluster galaxy (BCG). Using Chandra X-ray data, we construct thermodynamic profiles and determine the properties of the intracluster medium. The cool core nature of the cluster is supported by a centrally-peaked density profile and low central entropy ($K_0=18_{-9}^{+11}$ keV cm$^2$), which we estimate assuming an isothermal temperature profile due to the limited spectral information given the distance to the cluster. Using the density profile and gas cooling time inferred from the X-ray data, we find a mass cooling rate of $\dot{M}_\mathrm{cool}=100_{-60}^{+90}~M_\odot$ yr$^{-1}$. From optical spectroscopy and photometry around the [O II] emission line, we estimate that the BCG star formation rate is SFR$_\mathrm{[O~II]}=1.7_{-0.6}^{+1.0}~M_\odot$ yr$^{-1}$, roughly two orders of magnitude lower than the predicted mass cooling rate. In addition, using ATCA radio data at 2.1 GHz, we measure a radio jet power of $P_\mathrm{cav}=3.2_{-1.3}^{+2.1}\times10^{44}$ erg s$^{-1}$, which is consistent with the X-ray cooling luminosity ($L_\mathrm{cool}=1.9_{-0.5}^{+0.2}\times10^{44}$ erg s$^{-1}$ within $r_\mathrm{cool}=43$ kpc). These findings suggest that SPT0607 is a relaxed, cool core cluster with AGN-regulated cooling at an epoch shortly after cluster formation, implying that the balance between cooling and feedback can be reached quickly. We discuss implications for these findings on the evolution of AGN feedback in galaxy clusters.

description: We evaluate the information geometric complexity of entropic motion on low-dimensional Gaussian statistical manifolds in order to quantify how difficult is making macroscopic predictions about a systems in the presence of limited information. Specifically, we observe that the complexity of such entropic inferences not only depends on the amount of available pieces of information but also on the manner in which such pieces are correlated. Finally, we uncover that for certain correlational structures, the impossibility of reaching the most favorable configuration from an entropic inference viewpoint, seems to lead to an information geometric analog of the well-known frustration effect that occurs in statistical physics.

Towards an Online Database of Ancient Dramatic Meters

Subjects: Meter; Euripides; XML-TEI annotation; tragedy; database; JavaScript; JSON.

description: The authors of this paper, in cooperation with others, are working to create an online, open access database that presents and analyzes the metrical patterns of all Greek and Roman drama. We have begun with Euripides, creating XML versions of each play’s Greek text and translation, using for lyric sections the scansions of Frederico Lourenço’s The Lyric Metres of Euripidean Drama. The text is marked with various XML features indicating speaker changes, meters, metra/cola, periods, and basic divisions of the play. Each syllable of the play is identified and tagged as long or short via a combination of automatic and manual scansion. With the help of JavaScript and standard web design tools such as HTML and CSS, the XML versions of the plays are then used to create a website that shows scansion throughout the plays, displays metrical patterns in ways easy to comprehend, and allows one to see numerous statistical features of the tragedians’ use of meter. Alongside the XML documents, we make use of JSON files to generate a navigational grid, keep track of meters used in the play, connect the Greek text and the translation, and associate the names of characters with information such as their gender and status. It is hoped that when completed the database will be useful not only to scholars interested in Greek drama’s meter and music, but also to students and theater practitioners.

description: In this set of notes we simplify the formulation of the Poincare'-invariant effective string theory in D dimensions by adding an intrinsic metric and embedding its dynamics into the Polyakov formalism. We use this formalism to construct operators order by order in the inverse physical length of the string, in a fully gauge-invariant framework. We use this construction to discuss universality and nonuniversality of observables up to and including next-to-next-to-leading order in the long string expansion.

description: We present EUV solar observations showing evidence for omnipresent jetting activity driven by small-scale magnetic reconnection at the base of the solar corona. We argue that the physical mechanism that heats and drives the solar wind at its source is ubiquitous magnetic reconnection in the form of small-scale jetting activity (i.e., a.k.a. jetlets). This jetting activity, like the solar wind and the heating of the coronal plasma, are ubiquitous regardless of the solar cycle phase. Each event arises from small-scale reconnection of opposite polarity magnetic fields producing a short-lived jet of hot plasma and Alfvén waves into the corona. The discrete nature of these jetlet events leads to intermittent outflows from the corona, which homogenize as they propagate away from the Sun and form the solar wind. This discovery establishes the importance of small-scale magnetic reconnection in solar and stellar atmospheres in understanding ubiquitous phenomena such as coronal heating and solar wind acceleration. Based on previous analyses linking the switchbacks to the magnetic network, we also argue that these new observations might provide the link between the magnetic activity at the base of the corona and the switchback solar wind phenomenon. These new observations need to be put in the bigger picture of the role of magnetic reconnection and the diverse form of jetting in the solar atmosphere.

All-optical control of topological valley transport in graphene metasurfaces

description: We demonstrate that the influence of Kerr effect on valley-Hall topological transport in graphene metasurfaces can be used to implement an all-optical switch. In particular, by taking advantage of the large Kerr coefficient of graphene, the index of refraction of a topologically-protected graphene metasurface can be tuned via a pump beam, which results in an optically controllable frequency shift of the photonic bands of the metasurface. This spectral variation can in turn be readily employed to control and switch the propagation of an optical signal in certain waveguide modes of the graphene metasurface. Importantly, our theoretical and computational analysis reveals that the threshold pump power needed to optically switch ON/OFF the signal is strongly dependent on the group velocity of the pump mode, especially when the device is operated in the slow-light regime. This study could open up new routes towards active photonic nanodevices whose underlying functionality stems from their topological characteristics.

description: Birth environments of young stars have strong imprints on the star itself and their surroundings. We present a detailed analysis of the wealthy circumstellar environment around the young Herbig Ae/Be star TCrA. Our aim is to understand the nature of the stellar system and the extended circumstellar structures as seen in scattered light images. We conduct our analysis combining archival data, and new adaptive optics high-contrast and high-resolution images. The scattered light images reveal the presence of a complex environment composed of a bright forward scattering rim of the disk's surface that is seen at very high inclination, a dark lane of the disk midplane, bipolar outflows, and streamer features likely tracing infalling material from the surrounding birth cloud onto the disk. The analysis of the light curve suggests the star is a binary with a period of 29.6yrs. The comparison of the scattered light images with ALMA continuum and 12CO line emission shows the disk is in keplerian rotation, with the northern side of the outflowing material receding, while the southern side approaching the observer. The disk is itself seen edge-on. The direction of the outflows seen in scattered light is in agreement with the direction of the more distant molecular hydrogen emission-line objects (MHOs) associated to the star. Modeling of the SED using a radiative transfer scheme well agrees with the proposed configuration, as well as the hydrodynamical simulation performed using a Smoothed Particle Hydrodynamics code. We find evidence of streamers of accreting material around TCrA. These streamers connect the filament along which TCrA is forming with the outer parts of the disk, suggesting that the strong misalignment between the inner and outer disk is due to a change in the direction of the angular momentum of the material accreting on the disk during the late phase of star formation.

description: This is the third of a series of papers on three-loop computation of renormalization constants for Lattice QCD. Our main point of interest are results for the regularization defined by Iwasaki gauge action and n_f=4 Wilson fermions. Our results for quark bilinears renormalized according to the RI'-MOM scheme can be compared to non-perturbative results. The latter are available for Twisted Mass QCD: being defined in the chiral limit, renormalization constants must be the same. We also address more general problems. In particular, we discuss a few methodological issues connected to summing the perturbative series such as the effectiveness of Boosted Perturbation Theory and the disentanglement of irrelevant and finite volume contributions. Discussing these issues we consider ont only the new results of this paper, but also those for the regularization defined by tree-level Symanzik improved gauge action and n_f=2 Wilson fermions, which we presented in a recent paper of ours. We finally comment to which extent the techniques we put at work in the NSPT context can provide a fresher look into the lattice version of the RI'-MOM scheme.

description: The prediction of solar flares is of practical and scientific interest; however, many machine learning methods used for this prediction task do not provide the physical explanations behind a model's performance. We made use of two recently developed explainable artificial intelligence techniques called gradient-weighted class activation mapping (Grad-CAM) and expected gradients (EG) to reveal the decision-making process behind a high-performance neural network that has been trained to distinguish between MgII spectra derived from flaring and nonflaring active regions, a fact that can be applied to the task of short timescale flare forecasting. The two techniques generate visual explanations (heatmaps) that can be projected back onto the spectra, allowing for the identification of features that are strongly associated with precursory flare activity. We automated the search for explainable interpretations on the level of individual wavelengths, and provide multiple examples of flare prediction using IRIS spectral data, finding that prediction scores in general increase before flare onset. Large IRIS rasters that cover a significant portion of the active region and coincide with small preflare brightenings both in IRIS and SDO/AIA images tend to lead to better forecasts. The models reveal that MgII triplet emission, flows, as well as broad and highly asymmetric spectra are all important for the task of flare prediction. Additionally, we find that intensity is only weakly correlated to a spectrum's prediction score, meaning that low intensity spectra can still be of great importance for the flare prediction task, and that $78$% of the time, the position of the model's maximum attention along the slit during the preflare phase is predictive of the location of the flare's maximum UV emission

description: We propose Floquet chiral topological superconducting systems hosting Floquet Majorana fermions, which consist of hexagonal lattices in proximity to superconductors with shining circularly polarized light. Specially for bilayer graphene system, we demonstrate that there exist three topological phases determined by certain parameters, namely, the amplitude and frequency of the induced light. The number of chiral Floquet Majorana edge states is confirmed by calculating Chern number analytically and energy spectrum in ribbon geometry. Moreover, this proposal is generalized to other hexagonal lattice systems, such as monolayer graphene and silicene. Notably, the parameter range of induced light to achieve the chiral Floquet Majorana edge states is experimentally feasible, and the corresponding Floquet Majorana fermions can be probed based on differential conductance using scanning tunneling spectroscopy.

description: In 2000 the CRIMTA (Centro di Ricerca Interdipartimentale Multimediale sul Teatro Antico) was founded at the University of Pavia. Besides promoting various research activities and publications, the Centre owns an audiovisual fund with near a hundred videos of performances and films inspired by ancient dramas. In recent years, the CRIMTA fund has ensured the possibility to consult the videos for both academic and didactic purposes. A composite audience (researchers, teachers, theatre professionals) was thus able to access a valuable collection of materials that are often difficult to find. From its foundation, however, the role of archives has changed and must deal with the needs of an increasingly international research landscape, as well as with new teaching tools and strategies. Since October 2019, the CRIMTA has been reflecting on the digitization of its holdings. With our paper, we want to illustrate the actions that will lead to the creation of a digital version of the CRIMTA archive. This initiative will be possible in collaboration with the Digital Library Project of the University of Pavia, which is providing for the digitization of some funds from the Pavia libraries. The objective of this initiative is twofold: conservation and access. On the one hand, there is a technical need to preserve the fund, which, otherwise, risks deteriorating and being lost; on the other hand, the digitization would allow greater accessibility of documents, a need which, during the recent sanitary emergence, has become central. The paper will also provide an opportunity to reflect on the advantages of a digital archive for the performances of ancient dramas, in terms of accessibility and usability, but also some difficulties and limits, not only technical, of such a project.

Entropy Current from Partition Function: One Example

description: In hydrodynamics the existence of an entropy current with non-negative divergence is related to the existence of a time-independent solution in a static background. Recently there has been a proposal for how to construct an entropy current from the equilibrium partition function of the fluid system. In this note, we have applied this algorithm for the charged fluid at second order in derivative expansion. From the partition function we first constructed one example of entropy current with non-negative divergence upto the required order. Finally we extended it to its most general form, consistent with the principle of local entropy production. As a by-product we got the constraints on the second order transport coefficients for a parity even charged fluid, but in some non-standard fluid frame.

description: In this paper classical solutions of the degenerate fifth Painlevé equation are classified, which include hierarchies of algebraic solutions and solutions expressible in terms of Bessel functions. Solutions of the degenerate fifth Painlevé equation are known to expressible in terms of the third Painlevé equation. Two applications of these classical solutions are discussed, deriving exact solutions of the complex sine-Gordon equation and of the coefficients in the three-term recurrence relation associated with generalised Charlier polynomials.

Publisher: name: FuturoClassico FCl
Year: 2022
Subjects: Aristophanes; Menander; Greek Comedy; database; private money; public finances.

description: This article presents the ongoing project of a digital archive dedicated to public finance and private wealth in Greek comedy. The database aspires to provide scholars with a helpful tool to analyze and interpret the development of various socio-economical aspects as well as their perceptions in fifth- and fourth-century Athens, without losing sight of the poetic and dramaturgical functions of money and wealth in comedy. The first section of the contribution explores the ideological relevance of such themes in the poetics of Aristophanes and Menander; the second one focuses on the organizational criteria of the database, structured in lexical and thematic categories, and suggests possible research pathways based on the collected data of the archive.

description: The phase separation in lipid bilayers that include negatively charged lipids is examined experimentally. We observed phase-separated structures and determined the membrane miscibility temperatures in several binary and ternary lipid mixtures of unsaturated neutral lipid, dioleoylphosphatidylcholine (DOPC), saturated neutral lipid, dipalmitoylphosphatidylcholine (DPPC), unsaturated charged lipid, dioleoylphosphatidylglycerol (DOPG$^{\scriptsize{(-)}}$), saturated charged lipid, dipalmitoylphosphatidylglycerol (DPPG$^{\scriptsize{(-)}}$), and cholesterol. In binary mixtures of saturated and unsaturated charged lipids, the combination of the charged head with the saturation of hydrocarbon tail is a dominant factor for the stability of membrane phase separation. DPPG$^{\scriptsize{(-)}}$ enhances phase separation, while DOPG$^{\scriptsize{(-)}}$ suppresses it. Furthermore, the addition of DPPG$^{\scriptsize{(-)}}$ to a binary mixture of DPPC/cholesterol induces phase separation between DPPG$^{\scriptsize{(-)}}$-rich and cholesterol-rich phases. This indicates that cholesterol localization depends strongly on the electric charge on the hydrophilic head group rather than on the ordering of the hydrocarbon tails. Finally, when DPPG$^{\scriptsize{(-)}}$ was added to a neutral ternary system of DOPC/DPPC/Cholesterol (a conventional model of membrane rafts), a three-phase coexistence was produced. We conclude by discussing some qualitative features of the phase behaviour in charged membranes using a free energy approach.

description: Context: On 2020 May 30, small and short-lived EUV brightenings were observed in the Quiet Sun (QS) during a four minutes sequence by EUI/HRIEUV on board Solar Orbiter. Their physical origin and possible impact on coronal or Transition Region (TR) heating are still to be determined. Aims: Our aim is to derive the statistical thermal evolution of these events in order to establish their coronal or TR origin. Methods. Our thermal analysis takes advantage of the multithermal sensitivity of the Atmospheric Imaging Assembly (AIA) imager on board the Solar Dynamics Observatory (SDO). We first identified these HRIEUV events in the six coronal bands of AIA. We then performed a statistical time lag analysis, which quantifies the delays between the light curves from different bands. These time lags can give significant insights into the temperature evolution of these events. The analysis is performed taking into account the possible contribution to the results from the background and foreground emissions. Results: The events are characterized by time lags inferior to the AIA cadence of 12 s, for all nine couples of AIA bands analyzed. Our interpretation is the possible co-presence of events which reach or do not reach coronal temperatures ($\approx$ 1MK). We believe that the cool population dominates the events analyzed in this work.

description: We discuss the $β$-deformation of $AdS_5\times S^5$ which incorporates the $SL(2,\mathbb{R})$ symmetry of the type IIB theory. The axion-dilaton is identified with a two-torus from an eleven dimensional viewpoint. We consider the null geodesic with equal component angular momenta to take the Penrose limit of the deformed $AdS_5\times S^5$. We study the bosonic part of the string sigma model and the spectrum of the string in the pp-wave background.

description: Alchemical free energy methods have found tremendous success over the last few decades, becoming key components of drug discovery pipelines. Despite many and ongoing innovations  in this area, with several methodological improvements published each year, it remains challenging to consistently run free energy campaigns using state-of-the-art tools and best practices. In many cases, doing so requires expert knowledge, and/or the use of expensive closed source software. The Open Free Energy Consortium (https://openfree.energy/) was created with the aim of addressing these issues. A joint effort between academic and industry partners, the consortium aims to create and maintain reproducible and extensible open source toolkits for running large scale free energy campaigns. The initial flagship product of the Open Free Energy Consortium is the OpenFE toolkit (https://github.com/OpenFreeEnergy/openfe/), a permissively licensed open-source Python framework to setup, calculate, and analyze relative binding free energies.
Here we present the first benchmark results of the OpenFE toolkit. We compare the accuracy of ΔΔG estimates for approximately 200 ligand transformations calculated using the OpenFE toolkit with the OpenMM molecular dynamics engine, against previously published benchmark systems. We also assess the relative compute performance and accuracy of various equilibrium and non-equilibrium methods, including Hamiltonian replica exchange, self-adjusted mixture sampling, and non-equilibrium switching. Finally, we detail next steps for the toolkit, including the addition of support for other molecular dynamics engines, absolute binding free energies, and the ongoing curation of protein-ligand free energy benchmarks.
Archiving and Interpreting Greek and Roman Theatre: The Archive as Engine Room and Digital Hub

Publisher: name: FuturoClassico FCl
Year: 2022
Subjects: Archives; databases; performance; ebooks; blogs; podcasts; archival theory; theatre practice; translation theory and practice.

description: From the outset, the APGRD was sited at the interface between scholarship and practice. Like most modern archives, it is a real space, a room, with books, objects and documents. But it is also a virtual space with online events, databases, and digitised collections and digital connections with other collections. In many ways, the archive needs to function very much like an engine room of an organisation, where its ‘mechanical’ parts and its fuel are stored and where there is a regular interchange of ideas. It is a ‘reopened’ theatre archive that aims to promote research, pedagogy and creativity and demonstrates that they not only need to co-exist, but that their co-dependence is necessary to underpin the study of dramatic scripts, ancient and modern.

Lessico Digitale della Commedia Greca (LDCG): testo, scena, ricezione. Il bomolochos e la voce di Aristofane nell’archaia

Subjects: Buffoonery; poetics; ancient comedy; Aristophanes.

description: With the vocabulary of buffoonery (βωμολοχ-) Aristophanes often rejects comic entertainement of a trite and banal sort. In spite of those passages, scholarship has attempted to pin down the bomolochos as a highly specific character but, as Dionysus’ character in the Frogs shows, utterances of that type are not at odds with the severe Aristophanic claim to poetic inventiveness and refinement.

description: We demonstrate that light charged and extra neutral scalars in the (100-200) GeV mass range pass the potentially dangerous flavor constraints in a particular class of two-Higgs-doublet model which has appropriately suppressed flavor-changing neutral currents at tree level. We study their decay branching ratios into various fermionic final states and comment on the possibility of their detection in the collider experiments. We also remark on how their trademark decay signatures can be used to discriminate them from the light nonstandard scalars predicted in other two-Higgs-doublet models.
