Additional notes: Originally described as Targionia quohogiformis Merrill, 1923, and subsequently moved to Palinaspis quohogiformis (Merrill, 1923) by Ferris (1941). According to Merril (1923), syntype slides were deposited with the U.S National Museum (USNM), Leland Stanford Junior University (now Stanford University), Massachusetts Agricultural College (now University of Massachusetts Amherst), State Plant Board of Florida (now FSCA), and the author’s collection. It is unknown how many syntype specimens were deposited at each institution.

description: Cosmological perturbation theory is an example of a gauge theory, where gauge transformations correspond to changes in the space-time coordinate system. To determine physical quantities, one is free to introduce gauge conditions (\ie to work with specific space-time coordinates), and such conditions are often used to simplify technical aspects of the calculation or to facilitate the interpretation of the physical degrees of freedom. Some of the prescriptions introduced in the literature are known to fix the gauge only partially, but it is commonly assumed that the remaining gauge degrees of freedom can be fixed somehow. In this work, we show that this is not necessarily the case, and that some of these gauges are indeed pathological. We derive a systematic procedure to determine whether a gauge is pathological or not, and to complete partially-fixed gauges into healthy gauges when this is possible. In this approach, the Lagrange multipliers (\ie the perturbed lapse and shift in the ADM formalism) cannot appear in the off-shell definition of the gauges, they necessarily arise as on-shell consequences of the gauge conditions. As illustrative applications, we propose an alternative, non-pathological formulation of the synchronous gauge, and we show that the uniform-expansion gauge (as well as any gauge ensuring vanishing lapse perturbations) can hardly be made healthy. Our methodology also allows us to construct all gauge-invariant variables. We further show that our non-pathological criterion for gauges is also the one that ensures Dirac brackets to be properly defined. This allows cosmological perturbations to be quantised in a gauge-fixed way. We finally discuss possible generalisations of our formalism.

Type locality. Chapada, Brazil.
Remarks. A species that shows morphological similarities to A. bartletti n. sp., A. egregia, A. maryannae, and A. russelli. These species may form a complex within the genus. The species is associated with the Chaco floristic province based on the collection localities of specimens studied from Argentina (Sanborn & Heath 2014). The species extends into other floristic provinces as the Chaco does not cover the range of reported localities for the species.
Distribution. Specimens have been reported previously from Brazil (Metcalf 1963; Sanborn 2013), Venezuela (Sanborn 2007), and Argentina (Sanborn & Heath 2014). The distribution of the species is expanded here to include Bolivia and French Guiana.

ECP also examined photographs of the five slides with the same label data in the Bohart collection at UC Davis (where most of Ferris’s collection and type material was deposited) but they are not labeled as type material and the handwriting differs from the slides deposited at FSCA. We have an additional 9 paratype slides in the FSCA with the same label data as the syntypes reported here.

Subjects: subject: Logic in Computer Science (cs.LO)

description: In this note, we introduce the notion of support graph to define explanations for any model of a logic program. An explanation is an acyclic support graph that, for each true atom in the model, induces a proof in terms of program rules represented by labels. A classical model may have zero, one or several explanations: when it has at least one, it is called a justified model. We prove that all stable models are justified whereas, in general, the opposite does not hold, at least for disjunctive programs. We also provide a meta-programming encoding in Answer Set Programming that generates the explanations for a given stable model of some program. We prove that the encoding is sound and complete, that is, there is a one-to-one correspondence between each answer set of the encoding and each explanation for the original stable model.

description: Decentralized finance (DeFi) has been the target of numerous profit-driven crimes, but the prevalence and cumulative impact of these crimes have not yet been assessed. This study provides a comprehensive assessment of profit-driven crimes targeting the DeFi sector. We collected data on 1141 crime events from 2017 to 2022. Of these, 1036 were related to DeFi (the main focus of this study) and 105 to centralized finance (CeFi). The findings show that the entire cryptoasset industry has suffered a minimum loss of US$30B, with two-thirds related to CeFi and one-third to DeFi. Focusing on DeFi, a taxonomy was developed to clarify the similarities and differences among these crimes. All events were mapped onto the DeFi stack to assess the impacted technical layers, and the financial damages were quantified to gauge their scale. The results highlight that during an attack, a DeFi actor (an entity developing a DeFi technology) can serve as a direct target (due to technical vulnerabilities or exploitation of human risks), as a perpetrator (through malicious uses of contracts or market manipulations), or as an intermediary (by being imitated through, for example, phishing scams). The findings also show that DeFi actors are the first victims of crimes targeting the DeFi industry: 52% of events targeted them, primarily due to technical vulnerabilities at the protocol layer, and these events accounted for 83% of all financial damages. Alternatively, in 41% of events, DeFi actors were themselves malicious perpetrators, predominantly misusing contracts at the cryptoasset layer (e.g. rug pull scams). However, these events accounted for only 17% of all financial damages. The study offers a preliminary assessment of the size and scope of crime events within the DeFi sector and highlights the vulnerable position of DeFi actors in the ecosystem.

description: The artistic research work is concerned with webs of transnational artistic solidarity, especially those ingrained in the Nonaligned Movement (NAM), which embraced differences and united them in a common anti-imperialist and anti-colonial fight. Taking the museum as an artefact of historically situated solidarity, the project examines the instruments of transnational art solidarity for conceiving, developing and implementing decolonial cultural practices today. The main research question regards thinking about whether and how the emancipatory potential of the transnational art solidarity can be extracted, recuperated and translated when dealing with present issues of cultural decolonisation. Three museums founded on the bases of international solidarity and donations of artworks form the case study. Consequently, the research findings are systematised in three discourses: The Autonomous Museum; The Decolonial Museum; and The Museum in Exile.
description: Die künstlerische Forschungsarbeit befasst sich mit den Netzwerken der transnationalen künstlerischen Solidarität, insbesondere denen, die zwischen den Ländern des Globalen Südens zwischen den 1960er und den 1980er entstanden sind. Ausgehend von dem Museum als einem Artefakt historisch verankerter Solidarität untersucht das Projekt die Instrumente der transnationalen Kunstsolidarität für die Konzeption, Entwicklung und Umsetzung dekolonialer kultureller Praktiken heute. Die Hauptforschungsfrage besteht darin, ob und wie das emanzipatorische Potenzial der transnationalen Kunstsolidarität für die Auseinandersetzung mit aktuellen Fragen der kulturellen Dekolonisierung genutzt, zurückgewonnen und übersetzt werden kann. Drei Museen, die auf der Grundlage von Schenkungen von Kunstwerken gegründet wurden, bilden die Fallstudie. Folglich werden die Forschungsergebnisse in drei Diskursen systematisiert: Das autonome Museum, das dekoloniale Museum und das Museum im Exil.

description: Ultra-diffuse galaxies (UDGs) exhibit morphological similarities with other low-luminosity galaxies indicating a possible evolutionary connection. We investigate for common dynamical characteristics of isolated, HI-rich UDGs with other low luminosity field galaxies, namely the low surface brightness galaxies (LSBs) and the dwarf irregulars (dIrrs). From the galaxy scaling relation studies, we note that UDGs and LSBs constitute statistically different populations. However, for UDGs and dIrrs, the null hypotheses of these statistical tests cannot be rejected : stellar mass versus atomic hydrogen mass; stellar mass versus dynamical mass; and dark matter core density versus core radius mass scaling. Interestingly, the dynamical models suggest that UDGs, LSBs and dIrrs constitute different galaxy populations as reflected by their radial-to-vertical velocity dispersion, and the rotational velocity-to-total stellar velocity dispersion. Finally, we observe that the total HI and stellar mass mostly regulate the variance in the structural and kinematical data both for the UDGs and dIrrs, while the ratio of radial-to-vertical velocity dispersion, and the total HI mass dominate the same in LSBs. UDGs and LSBs represent statistically different galaxy populations with respect to their mass and structural properties. But the fact that their structural parameters follow the same distributions is not ruled out. However, UDGs, dIrrs and LSBs constitute very different populations as far as their kinematical parameters are concerned. Finally, we note that the variation in the structural and kinematical data of both the UDGs and the dIrrs is mostly accounted for by their stellar mass and HI mass, whereas for the LSBs, the same is explained by the ratio of the radial-to-vertical stellar dispersion followed by the HI mass. Thus we conclude that the UDGs and dIrrs to share common dynamical lineage.

Ethmia guangzhouensis Liu, 1980: 274. Type locality: Guangdong, China.
Ethmia pseudozygospila Kun & Szabóky, 2000: 71, syn. nov. Type locality: Taiwan, China.
Material examined. Paratypes: 3 3, 2 ƤƤ, China: Botanical Garden (23°9' N, 113°20' E), Guangzhou City, Guangdong Province, 23.vi.1978, genitalia slide Nos. 781053/106Ƥ/1093 (IZCAS).

Diagnosis. This species is similar externally to E. zygospila Meyrick, 1934, but can be distinguished by the forewing having one indistinctly marked V-shaped pattern, while in the latter species, the forewing has two Vshaped patterns longitudinally. It is close to E. damaoshanae Wang & Zheng, 1997 in the male genitalia, but can be recognizd by the cucullus having a blunt dorsoventral tip, while the cucullus of E. damaoshanae has a pointed dorsoventral tip.
Distribution. China (Guangzhou, Taiwan).
Remarks. Liu (1980) described E. guangzhouensis based on five male and four female specimens collected from Guangzhou, with illustrations of male and female genitalia. After checking three male and two female paratypes, we found that the forewing patterns and the genitalia of E. pseudozygospila Kun & Szabóky, 2000, known from Taiwan are identical to those of E. guangzhouensis Liu. So we regard E. pseudozygospila Kun & Szabóky, 2000 as a synonym of E. guangzhouensis Liu.

A regularity result for the Fokker-Planck equation with non-smooth drift and diffusion

description: The goal of this paper is to study weak solutions of the Fokker-Planck equation. We first discuss existence and uniqueness of weak solutions in an irregular context, providing a unified treatment of the available literature along with some extensions. Then, we prove a regularity result for distributional solutions under suitable integrability assumptions, relying on a new, simple commutator estimate in the spirit of DiPerna-Lions' theory of renormalized solutions for the transport equation. Our result is somehow transverse to Theorem 4.3 of [15]: on the diffusion matrix we relax the assumption of Lipschitz regularity in time at the price of assuming Sobolev regularity in space, and we prove the regularity (and hence the uniqueness) of distributional solutions to the Fokker-Planck equation.

Remarks. The species is most similar morphologically to A. albimaculosa n. sp. The species has been associated with the Chaco floristic province in Argentina (Sanborn, et al. 2011a; Sanborn & Heath 2014) but is associated with other plant communities across the range of the species as the Chaco does not extend to the type locality.
Distribution. Specimens have been reported previously from Colombia, Venezuela (Metcalf 1963; Sanborn 2013), and Argentina (Sanborn & Heath 2014).

Note on the group of vertical diffeomorphisms of a principal bundle, and its relation to the Frölicher-Nijenhuis bracket

description: The group of vertical diffeomorphisms of a principal bundle forms the generalised action Lie groupoid associated to the bundle. The former is generated by the group of maps with value in the structure group, which is also the group of bisections of the groupoid. The corresponding Lie algebra of general vertical vector fields is generated by maps with value in the Lie algebra of the structure group. The bracket on these maps, induces by the bracket of vertical vector fields, is an ``extended" bracket on gauge parameters: it has been introduced heuristically in physics, notably in the study asymptotic symmetries of gravity. Seeing the set of Lie algebra-valued maps as sections of the action Lie algebroid associated to the bundle, the extended bracket is understood to be a Lie algebroid bracket on those sections. Here, we highlight that this bracket can also be seen to arise from the Frölicher-Nijenhuis bracket of vector-valued differential forms. The benefit of this viewpoint is to insert this extended bracket within the general framework of derivations of forms on the bundle. Identities relating it to usual operations -- inner product, exterior and (Nijenhuis-) Lie derivative -- are immediately read as special cases of general results. We also look at the generalised gauge transformations induced by vertical diffeomorphisms, and discuss their peculiar features. In particular, locally, and contrary to standard gauge transformations arising from vertical bundle automorphisms, they are distinguishable from local gluings when iterated. Yet, the gauge principle still holds.

The dressing field method for diffeomorphisms: a relational framework
Creators: name: Andre, Jordan T. Francois
Publisher: name: arXiv
Year: 2023
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: The dressing field method is a tool to reduce gauge symmetries. Here we extend it to cover the case of diffeomorphisms. The resulting framework is a systematic scheme to produce Diff(M)-invariant objects, which has a natural relational interpretation.
 Its precise formulation relies on a clear understanding of the bundle geometry of field space. By detailing it, among other things we stress the geometric nature of field-independent and field-dependent diffeomorphisms, and highlight that the heuristic "extended bracket" for field-dependent vector fields often featuring in the covariant phase space literature can be understood as arising from the Frölicher-Nijenhuis bracket. Furthermore, by articulating this bundle geometry with the covariant phase space approach, we give a streamlined account of the elementary objects of the (pre)symplectic structure of a Diff(M)-theory: Noether charges and their bracket, as induced by the standard prescription for the presymplectic potential and 2-form. We give conceptually transparent expressions allowing to read the integrability conditions and the circumstances under which the bracket of charge is Lie, and the resulting Poisson algebras of charges are central extensions of the Lie algebras of field-independent ($\mathfrak{diff}(M)$) and field-dependent vector fields.
 We show that, applying the dressing field method, one obtains a Diff(M)-invariant and manifestly relational formulation of a general relativistic field theory. Relying on results just mentioned, we easily derive the "dressed" (relational) presymplectic structure of the theory. This reproduces or extends results from the gravitational edge mode and gravitational dressing literature. In addition to simplified technical derivations, the conceptual clarity of the framework supplies several insights and allows us to dispel misconceptions.

Updated Proper Motion of the Neutron Star in the Supernova Remnant Cassiopeia A

description: In this paper, we present updated estimates of the velocity of the neutron star (NS) in the supernova remnant (SNR) Cassiopeia A using over two decades of Chandra observations. We use two methods: 1.) recording NS positions from dozens of Chandra observations, including the astrometric uncertainty estimates on the data points but not correcting the astrometry of the observations, and 2.) correcting the astrometry of the 13 Chandra observations that have a sufficient number of point sources with identified Gaia counterparts. For method #1, we observe a heliocentric velocity of 275 $\pm$ 121 km/s, with an angle of 177 $\pm$ 22 degrees east of north. For method #2, we observe a heliocentric velocity of 436 $\pm$ 89 km s$^{-1}$ at an angle of 158 $\pm$ 12 degrees. Correcting for galactic rotation and the sun's peculiar motion decreases these estimates to 256 km s$^{-1}$ at 167$^\circ$ and 433 km s$^{-1}$ at 151$^\circ$, respectively. Both of our estimates match with the explosion-center-estimated velocity of $\sim$350 km s$^{-1}$ and the previous 10--year baseline proper motion measurement of 570 $\pm$ 260 km s$^{-1}$, but our use of additional data over a longer baseline has led to a smaller uncertainty by a factor of 2--3. Our estimates rule out velocities $\gtrsim$600 km s$^{-1}$ and better match with simulations of Cassiopeia~A that include NS kick mechanisms.

description: Nicolai maps offer an alternative description of supersymmetric theories via nonlinear and nonlocal transformations characterized by the so-called `free-action' and `determinant-matching' conditions. The latter expresses the equality of the Jacobian determinant of the transformation with the one obtained by integrating out the fermions, which so far have been considered only to quadratic terms. We argue that such a restriction is not substantial, as Nicolai maps can be constructed for arbitrary nonlinear sigma models, which feature four-fermion interactions. The fermionic effective one-loop action then gets generalized to higher loops and the perturbative tree expansion of such Nicolai maps receives quantum corrections in the form of fermion loop decorations. The `free-action condition' continues to hold for the classical map, but the `determinant-matching condition' is extended to an infinite hierarchy in fermion loop order. After general considerations for sigma models in four dimensions, we specialize to the case of $\mathbb{C}\mathrm{P}^N$ symmetric spaces and construct the associated Nicolai map. These sigma models admit a formulation with only quadratic fermions via an auxiliary vector field, which does not simplify our analysis.
