description: The geometry, kinematics, and mode of back-arc extension along the Andaman Sea plate boundary are refined using a new set of significantly improved hypocenters, global centroid moment tensor (CMT) solutions, and high-resolution bathymetry. By applying cross-correlation and double-difference (DD) algorithms to regional and teleseismic waveforms and arrival times from International Seismological Centre and National Earthquake Information Center bulletins (1964–2009), we resolve the fine-scale structure and spatiotemporal behavior of active faults in the Andaman Sea. The new data reveal that back-arc extension is primarily accommodated at the Andaman Back-Arc Spreading Center (ABSC) at ~10°, which hosted three major earthquake swarms in 1984, 2006, and 2009. Short-term spreading rates estimated from extensional moment tensors account for less than 10% of the long-term 3.0–3.8 cm/yr spreading rate, indicating that spreading by intrusion and the formation of new crust make up for the difference. A spatiotemporal analysis of the swarms and Coulomb-stress modeling show that dike intrusions are the primary driver for brittle failure in the ABSC. While spreading direction is close to ridge normal, it is oblique to the adjacent transforms. The resulting component of E-W extension across the transforms is expressed by deep basins on either side of the rift and a change to extensional faulting along the West Andaman fault system after the Mw = 9.2 Sumatra-Andaman earthquake of 2004. A possible skew in slip vectors of earthquakes in the eastern part of the ABSC indicates an en-echelon arrangement of extensional structures, suggesting that the present segment geometry is not in equilibrium with current plate-motion demands, and thus the ridge experiences ongoing re-adjustment.

description: To analyze nonlinear dynamic systems, we developed a new technique based on the square matrix method. We propose this technique called the \convergence map" for generating particle stability diagrams similar to the frequency maps widely used in accelerator physics to estimate dynamic aperture. The convergence map provides similar information as the frequency map but in a much shorter computing time. The dynamic equation can be rewritten in terms of action-angle variables provided by the square matrix derived from the accelerator lattice. The convergence map is obtained by solving the exact nonlinear equation iteratively by the perturbation method using Fourier transform and studying convergence. When the iteration is convergent, the solution is expressed as a quasi-periodic analytical function as a highly accurate approximation, and hence the motion is stable. The border of stable motion determines the dynamical aperture. As an example, we applied the new method to the nonlinear optimization of the NSLS-II storage ring and demonstrated a dynamic aperture comparable to or larger than the nominal one obtained by particle tracking. The computation speed of the convergence map is 30 to 300 times faster than the speed of the particle tracking, depending on the size of the ring lattice (number of superperiods). The computation speed ratio is larger for complex lattices with low symmetry, such as particle colliders.

description: Limits on the tensor couplings generating a Fierz interference term, b, in mixed Gamow-Teller Fermi decays can be derived by combining data from measurements of angular correlation parameters in neutron decay, the neutron lifetime, and $G_{\text{V}}=G_{\text{F}} V_{ud}$ as extracted from measurements of the $\mathcal{F}t$ values from the $0^{+} \to 0^{+}$ superallowed decays dataset. These limits are derived by comparing the neutron $β$-decay rate as predicted in the standard model with the measured decay rate while allowing for the existence of beyond the standard model couplings. We analyze limits derived from the electron-neutrino asymmetry, $a$, or the beta-asymmetry, $A$, finding that the most stringent limits for $C_\text{T}/C_\text{A}$ under the assumption of no right-handed currents is $-0.0026 < C_\text{T}/C_\text{A} < 0.0024$ (95% C.L.) for the two most recent values of $A$.

REMARKS: Rondani (1848b: 106) described Tabanus piceiventris from just the female sex, without specifying the exact number of specimens and not giving a range of lengths, from material collected in South America by V. Ghiliani. Costa (1866: 38) listed a single MZUN specimen numbered “889”. We also found one syntype in this study. Philip (1965a: 121) and Fairchild (1971: 99) reported a single type specimen (♀) in the MZUN.Although Rondani (1848b: 63) only gave the type locality as “ Brasile ”, Papavero (1973: 343) gave a more accurate type locality based on a note in Spinola (1853) that said all specimens collected by Ghiliani in 1846 were collected in Belem, Pará, Brazil.

description: We consider stochastic and open quantum systems with a finite number of states, where a stochastic transition between two specific states is monitored by a detector. The long-time counting statistics of the observed realizations of the transition, parametrized by cumulants, is the only available information about the system. We present an analytical method for reconstructing generators of the time evolution of the system compatible with the observations. The practicality of the reconstruction method is demonstrated by the examples of a laser-driven atom and the kinetics of enzyme-catalyzed reactions. Moreover, we propose cumulant-based criteria for testing the non-classicality and non-Markovianity of the time evolution, and lower bounds for the system dimension. Our analytical results rely on the close connection between the cumulants of the counting statistics and the characteristic polynomial of the generator, which takes the role of the cumulant generating function.

description: The aim of this project is to explore the non-assimilation into Jewish American religious life of members of the fourth and final wave (1986-1989) of Soviet Jewish refugees to the United States. In the late 1980s, thousands of Soviet Jews came to the US with the help of American Jews. As is evident in American Jewish publications, though the American hosts expected the Soviet Jews to engage in Jewish religious life in America, they were often disappointed. So why have so many Soviet Jewish refugees not fully taken on Jewish cultural and religious identity after their immigration to the United States? In this paper I argue that despite the extraordinary efforts of the American Jewish community, the Soviet Jewish immigrants of the last wave have not taken on an American Jewish religious identity, in part because American and Soviet Jews have different understandings of what it means to be Jewish. Through a close examination of six interviews conducted with fourth-wave refugees, five publications on the subject of their integration by Jewish organizations, as well as two handbooks published by the Hebrew Immigrant Aid Society for Soviet Jews about American Jewish life, I demonstrate that the Soviet Jews in the US have created their own Jewish identity based on their experiences of Jewishness in the USSR, and engage in American Jewish religious life only in ways that are useful or meaningful to them in the context of this past. I also show that the American Jewish community has often had trouble understanding this, as is evident in the multitude of publications they have released in which they explore the potential reasons for this phenomenon and search for a solution to bring Soviet Jews into the American Jewish religious community. Within this analysis, I explore the concepts of identity, religiosity, and culture.

description: We study observation entropy (OE) for the Quantum kicked top (QKT) model, whose classical counterpart possesses different phases: regular, mixed, or chaotic, depending on the strength of the kicking parameter. We show that OE grows logarithmically with coarse-graining length beyond a critical value in the regular phase, while OE growth is much faster in the chaotic regime. In the dynamics, we demonstrate that the short-time growth rate of OE acts as a measure of the chaoticity in the system, and we compare our results with out-of-time-ordered correlators (OTOC). Moreover, we show that in the deep quantum regime, the results obtained from OE are much more robust compared to OTOC results. Finally, we also investigate the long-time behaviour of OE to distinguish between saddle-point scrambling and true chaos, where the former shows large persistent fluctuations compared to the latter.

description: Gravitational preferred frame effects are generally predicted by alternative theories that exhibit an isotropic violation of local Lorentz invariance of gravity. They are described by three parameters in the parametrized post-Newtonian formalism. One of their strong-field generalizations, $\hat α_2$, induces a precession of a pulsar's spin around its movement direction with respect to the preferred frame. We constrain $\hat α_2$ by using the non-detection of such a precession using the characteristics of the pulse profile. In our analysis we use a large number of observations from the 100-m Effelsberg radio telescope, which cover a time span of approximately 15 years. By combining data from two solitary millisecond pulsars, PSRs B1937+21 and J1744-1134, we get a limit of $|\hat α_2| < 1.6 \times 10^{-9}$ at 95% confidence level, which is more than two orders of magnitude better than its best weak-field counterpart from the Solar system.

description: Hydrothermal fluid circulation at mid-ocean ridges facilitates the exchange of heat and chemicals between the oceans and the solid Earth, and supports chemosynthetic microbial and macro-faunal communities. The structure and evolution of newly formed oceanic crust plays a dominant role in controlling the character and longevity of hydrothermal systems; however, direct measurements of subsurface processes remain technologically challenging to obtain. Previous studies have shown that tidally-induced stresses within the subseafloor modulate both fluid flow and microearthquake origin times. In this study, we observe systematic along-axis variations between peak microearthquake activity and maximum predicted tidal extension beneath the hydrothermal vent site at 9°50′N East Pacific Rise. We interpret this systematic triggering to result from pore-pressure perturbations propagating laterally through the hydrothermal system. Based on our observations and a one-dimensional pore pressure perturbation model, we estimate bulk permeability at ∼10⁻¹³ to 10⁻¹² m² within layer 2B over a calculated diffusive lengthscale of 2.0 km.

description: Le burnout est un syndrome qui touche particulièrement les enseignants. De plus, il a des effets négatifs non seulement sur l’enseignant touché, mais également sur son entourage, et en particulier sur ses élèves. Il est donc essentiel de bien comprendre ce phénomène afin de pouvoir mettre en place des stratégies de prévention. S’il existe des facteurs de risques, il existe également des facteurs de protection, parmi lesquels le plus étudié est le soutien social. Le soutien social est le soutien fourni par l’entourage de la personne, dans son milieu professionnel (collègues, direction) mais également dans sa vie privée (famille, amis). Le but du présent travail est d’analyser plus en détail la relation entre le soutien social et le burnout chez les enseignants. Pour ce faire, une revue de la littérature récente sur le sujet a été effectuée. Les articles ont été présélectionnés sur la base de mots-clés dans quatre bases de données. Différents articles ont ensuite été exclus, en raison de la langue de rédaction ou du fait qu’ils étaient eux-mêmes des méta-analyses, par exemple. Une liste de 16 articles a ainsi été constituée. Les principales caractéristiques et résultats de chaque étude ont été présentés de façon systématique sous forme de tableau. Les résultats confirment que le soutien social a un rôle protecteur sur le burnout. Cependant, la grande variété conceptuelle et méthodologique des études analysées a rendu difficile de les comparer. En effet, il n’existe pas de définition unanime du soutien social. Certaines études considèrent la source du soutien social (collègues ou amis, par exemple) alors que d’autres s’intéressent au type de soutien fourni. Une meilleure définition et une mesure de référence pour le soutien social pourrait permettre à l’avenir une meilleure compréhension des interactions entre soutien social et burnout ainsi qu’une meilleure prévention de ce dernier.

Identifiability of Cardiac Electrophysiology Models
Creators: name: Regulatory Catalog
Publisher: name: Zenodo
Year: 2023

description: This tool represents an implementation of an approach for optimal experimental design and estimability analysis for mechanistic models of cardiac electrophysiology to determine their ‘identifiability’. A model is identifiable if there are a unique set of parameters for a given model output. Cardiac electrophysiological computational models are comprised of numerous complex non-linear equations that predict the action potential in the heart at one or multiple sites. Many of these models have been shown to be non-identifiable such that multiple parameter sets give rise to the same model output. For the purpose of evaluating the ‘robustness’ of a model, both parameter sensitivity analysis and uncertainty quantification are important methods which fail when a model is non-identifiable.

description: We introduce (integro-differential) harmonic maps into spheres, which are defined as critical points of the Besov-Slobodeckij energy $\int\limits_Ω\int\limits_Ω \frac{|v(x)-v(y)|^{p_s}}{|x-y|^{n+sp_s}}\ dx\ dy$. For $p_s = 2$ these are the classical fractional harmonic maps first considered by Da Lio and Riviere. For $p_s \neq 2$ this is a new energy which has degenerate, non-local Euler-Lagrange equations. For the critical case, $p_s = n/s$, we show Holder continuity of these maps.

description: The Sasa-Satsuma equation, a higher-order nonlinear Schrödinger equation, is an important integrable equation, which displays the propagation of femtosecond pulses in optical fibers. In this paper, we investigate a generalized Sasa-Satsuma(gSS) equation. The Darboux transformation(DT) for the focusing and defocusing gSS equation is constructed. By using the DT, various of soliton solutions for the generalized Sasa-Satsuma equation are derived, including hump-type, breather-type and periodic soliton. Dynamics properties and asymptotic behavior of these soliton solutions are analyzed. Infinite number conservation laws and conserved quantities for the gSS equation are obtained.
Constraining gas disk structure in MY Lupi with submillimeter and UV models
Creators: name: Arulanantham, Nicole
Publisher: name: Zenodo
Year: 2020

description: Physical-chemical models generate detailed maps of carbon, nitrogen, oxygen, and hydrogen bearing molecules in protoplanetary disks. However, the vertical disk structure in these models is degenerate with the amount of UV flux reaching the gas. Flat, strongly irradiated disk models and flared, weakly irradiated systems produce similar molecular gas distributions, which makes it difficult to examine UV sensitive photochemical pathways in systems from which submillimeter gas emission has not been spatially resolved. We investigate whether ultraviolet emission lines from fluorescent molecular hydrogen can be used to break this degeneracy, by using the Dust and LInes (DALI) code to generate a grid of physical-chemical models based on the disk around MY Lupi. The 2-D distributions of vibrationally excited molecular hydrogen from each DALI model are then irradiated with LyA photons, which pump the gas into excited electronic states. The resulting fluorescent emission lines are compared directly to observed UV features in HST-COS spectra of MY Lupi, showing that the H2 lines are best fit by a flared disk model with strong FUV irradiation and a high gas mass. We conclude that emission lines from UV spectra can provide important constraints for physical-chemical models of gas disks.

description: We studied the anatomy of the fault system where the 2009 L'Aquila earthquake (M_W 6.1) nucleated by means of ~64 k high-precision earthquake locations spanning 1 year. Data were analyzed by combining an automatic picking procedure for P and S waves, together with cross-correlation and double-difference location methods reaching a completeness magnitude for the catalogue equal to 0.7 including 425 clusters of similar earthquakes. The fault system is composed by two major faults: the high-angle L'Aquila fault and the listric Campotosto fault, both located in the first 10 km of the upper crust. We detect an extraordinary degree of detail in the anatomy of the single fault segments resembling the degree of complexity observed by field geologists on fault outcrops. We observe multiple antithetic and synthetic fault segments tens of meters long in both the hanging wall and footwall along with bends and cross fault intersections along the main fault and fault splays. The width of the L'Aquila fault zone varies along strike from 0.3 km where the fault exhibits the simplest geometry and experienced peaks in the slip distribution, up to 1.5 km at the fault tips with an increase in the geometrical complexity. These characteristics, similar to damage zone properties of natural faults, underline the key role of aftershocks in fault growth and co-seismic rupture propagation processes. Additionally, we interpret the persistent nucleation of similar events at the seismicity cutoff depth as the presence of a rheological (i.e., creeping) discontinuity explaining how normal faults detach at depth.

description: How is the public-private organizational field of affordable housing finance impacting the organizations producing housing in urban neighborhoods? Drawing on interview data from 20 stakeholders involved in the Chicago affordable housing development process, this article contributes to literatures of housing policy and urban sociology. First, mapping out the process of affordable housing development, I show how organizations do not fit into dominant theoretical models present in urban planning, sociological, and housing policy literature. Specifically, I show how these models adopt units of analysis that miss crucial field effects of organizations on one another. Second, I emphasize that treating organizations as productive of social relations is essential to understanding the outcomes of affordable housing projects. By this I mean how organizations are beholden to one another in different ways, depending on legal structure, size, and financing pattern. A heterogeneity of organizational relations helps account for project siting patterns of affordable housing as well as the composition of the organizational field.

description: The high accuracy of space data increased the number of the periodicities determined for pulsating variable stars, but the mode identification is still a critical point in the non-asymptotic regime. We use regularities in frequency spacings for identifying the pulsation modes of the recently discovered delta Sct star ID 102749568. In addition to analysing CoRoT light curves (15252 datapoints spanning 131 days), we obtained and analysed both spectroscopic and extended multi-colour photometric data. We applied standard tools (MUFRAN, Period04, SigSpec, and FAMIAS) for time-series analysis. A satisfactory light-curve fit was obtaining by means of 52 independent modes and 15 combination terms. The frequency spacing revealed distinct peaks around large (25.55-31.43 microHz), intermediate (9.80, 7.66 microHz), and low (2.35 microHz) separations. We directly identified 9 modes, and the l and n values of other three modes were extrapolated. The combined application of spectroscopy, multi-colour photometry, and modelling yielded the precise physical parameters and confirmed the observational mode identification. The large separation constrained the log g and related quantities. The dominant mode is the radial first overtone.

description: The evolution of a dilute electron-positron fireball is calculated in the regime of strong magnetization and very high compactness (l ~10^3-10^8). Heating is applied at a low effective temperature (< 25 keV), and the fireball is allowed to expand, so that the formation of a black-body spectral distribution is inhibited by pair annihilation. The diffusion equation for Compton scattering is coupled to a single-temperature pair gas and an exact (trans-relativistic) cyclo-synchrotron photon source. We find that the photon spectrum develops a quasi-thermal peak, with a power-law slope below it that is characteristic of gamma-ray bursts. The formation of a thermal high-frequency spectrum is checked using the full kinetic equations at l ~ 10^3. These results have several implications for the central engine of GRBs, and the mechanism of energy transport. 1. Baryon rest mass carries less than ~ 10^{-5} of the energy flux at jet breakout inside ~ 10^{12} cm from the engine, with most carried by the magnetic field. 2. This degree of baryon purity points to the presence of an event horizon in the engine, and neutrons play a negligible role in the prompt emission mechanism. 3. X-ray flashes are emitted by outflows carrying enough baryons that the photosphere is pair-depleted, which we show results in faster thermalization. 4. The relation between observed peak frequency and burst luminosity is bounded below by the observed Amati et al. relation if jet Lorentz factor ~ 1/(opening angle) at breakout. 5. Stellar models are used to demonstrate an inconsistency between the highest observed GRB energies, and a hydrodynamic nozzle: magnetic collimation is required. 6. The magnetized pair gas is dilute enough that high-frequency Alfven waves may become charge starved. Finally, we suggest that limitations on magnetic reconnection from plasma collisionality have been overestimated.

description: Relocated hypocentral data from a 7-month deployment (October 2003 to April 2004) of ocean bottom seismometers provide an opportunity to map microearthquake frequency-magnitude distributions (FMDs) along the 9°49–52′N region on the East Pacific Rise. These analyses, which incorporate more than 9000 earthquakes, represent the first investigation of the 3-D spatial and temporal patterns of FMDs along any mid-ocean ridge spreading center. The data are described well by a Gutenberg-Richter model, indicating a power law or fractal relationship between earthquake size and frequency. The scaling exponent, or b value, shows significant spatial variability, exceeding a value of 2.0 at the shallowest depths on axis and dropping below 1.0 away from the axial trough. This spatial pattern is consistent with an inverse relationship between b value and ambient stress conditions, with the lowest stress levels at shallow depths and relatively high stress levels (or low pore pressures) observed away from the axial zone. Intermediate b values are observed on-axis above the ridge system's melt lens; however, within this region there also exists significant spatial variability. This indicates that stress conditions and/or structural heterogeneity may vary at subkilometer scales within the hydrothermal circulation cell. Although the observational period is characterized by increasing seismicity rates, building toward an eruptive episode in January 2006, the first-order spatial pattern of b values is sustained, with no overall temporal trend. As a byproduct of this b value analysis, the detection capabilities of the array are assessed empirically.

description: We use deep $8\:μm$ Spitzer-IRAC imaging of a massive Infrared Dark Cloud (IRDC) G028.37+00.07 to construct a Mid-Infrared (MIR) extinction map that probes mass surface densities up to $Σ\:\sim 1\:\rm{g~cm^{-2}}$ ($A_V\sim200\:$mag), amongst the highest values yet probed by extinction mapping. Merging with a NIR extinction map of the region, creates a high dynamic range map that reveals structures down to $A_V\sim1\:$mag. We utilize the map to: (1) Measure a cloud mass $\sim7\times10^4\:M_\odot$ within a radius of $\sim8\:$pc. $^{13}$CO kinematics indicate that the cloud is gravitationally bound. It thus has the potential to form one of the most massive young star clusters known in the Galaxy. (2) Characterize the structures of 16 massive cores within the IRDC, finding they can be fit by singular polytropic spheres with $ρ\propto{r}^{-k_ρ}$ and $k_ρ=1.3\pm0.3$. They have $\overlineΣ\simeq0.1-0.4\:\rm{g~cm^{-2}}$ --- relatively low values that, along with their measured cold temperatures, suggest magnetic fields, rather than accretion-powered radiative heating, are important for controlling fragmentation of these cores. (3) Determine the $Σ$ (equivalently column density or $A_V$) probability distribution function (PDF) for a region that is near complete for $A_V>3\:$mag. The PDF is well fit by a single log-normal with mean $\overline{A}_V\simeq9\:$mag, high compared to other known clouds. It does not exhibit a separate high-end power law tail, which has been claimed to indicate the importance of self-gravity. However, we suggest that the PDF does result from a self-similar, self-gravitating hierarchy of structure being present over a wide range of scales in the cloud.

description: The surface of a thin liquid film with nonconstant curvature flattens as a result of capillary forces. While this leveling is driven by local curvature gradients, the global boundary conditions greatly influence the dynamics. Here, we study the evolution of rectangular trenches in a polystyrene nanofilm. Initially, when the two sides of a trench are well separated, the asymmetric boundary condition given by the step height controls the dynamics. In this case, the evolution results from the leveling of two noninteracting steps. As the steps broaden further and start to interact, the global symmetric boundary condition alters the leveling dynamics. We report on full agreement between theory and experiments for: the capillary-driven flow and resulting time dependent height profiles; a crossover in the power-law dependence of the viscous energy dissipation as a function of time as the trench evolution transitions from two noninteracting to interacting steps; and the convergence of the profiles to a universal self-similar attractor that is given by the Green's function of the linear operator describing the dimensionless linearized thin film equation.

description: Ultradiscretization with negative values is a long-standing problem and several attempts have been made to solve it. Among others, we focus on the symmetrized max-plus algebra, with which we ultradiscretize the discrete sine-Gordon equation. Another ultradiscretization of the discrete sine-Gordon equation has already been proposed by previous studies, but the equation and the solutions obtained here are considered to directly correspond to the discrete counterpart. We also propose a noncommutative discrete analogue of the sine-Gordon equation, reveal its relations to other integrable systems including the noncommutative discrete KP equation, and construct multisoliton solutions by a repeated application of Darboux transformations. Moreover, we derive a noncommutative ultradiscrete analogue of the sine-Gordon equation and its 1-soliton and 2-soliton solutions, using the symmetrized max-plus algebra. As a result, we have a complete set of commutative and noncommutative versions of continuous, discrete, and ultradiscrete sine-Gordon equations.

description: For the one-dimensional repulsive Bose gas (Lieb-Liniger model), we study a special class of highly-excited states obtained by giving a finite momentum to subgroups of particles. These states, which correspond to `splitting' the ground state Fermi sea-like quantum number configuration, are zero-entropy states which display interesting properties more normally associated to ground states. Using a numerically exact method based on integrability, we study these states' excitation spectrum, density correlations and momentum distribution functions. These correlations display power-law asymptotics, and are shown to be accurately described by an effective multicomponent Tomonaga-Luttinger liquid theory whose parameters are obtained from Bethe Ansatz. The non-universal correlation prefactors are moreover obtained from integrability, yielding a completely parameter-free fit of the correlator asymptotics.

description: With the development of decision systems and specially data warehouses, the visibility of the data warehouse design before its creation has become essential, and that because of data warehouse importance as considered as the unique data source giving meaning to the decision. In a decision system the proper functioning of a data warehouse resides in the smooth running of the middleware tools ETC step one hand, and the restitution step through the data mining, reporting solutions, dashboards... etc other. The large volume of data that passes through these stages require an optimal design for a highly efficient decision system, without disregarding the choice of technologies that are introduced for the data warehouse implementation such as: database management system, the type of server operating systems, physical server architecture (64-bit, for example) that can be a benefit performance of this system. The designer of the data warehouse should consider the effectiveness of data query, this depends on the selection of relevant indexes and their combination with the materialized views, note that the index selection is a NPcomplete problem, because the number of indexes is exponential in the total number of attributes in the database, So, it is necessary to provide, while the data warehouse design, the suitable type of index for this data warehouse. This paper presents a comparative study between the index B-tree type and type Bitmap, their advantages and disadvantages, with a real experiment showing that its index of type Bitmap more advantageous than the index B-tree type.

description: Axions are a well-motivated dark matter candidate, with a host of experiments around the world searching for direct evidence of their existence. The ORGAN Experiment is a type of axion detector known as an axion haloscope, which takes the form of a cryogenic resonant cavity embedded in a strong magnetic field. ORGAN recently completed Phase 1a, a scan for axions around 65 \textmu eV, and placed the most stringent limits to date on the dark matter axion-photon coupling in this region, $|g_{aγγ}|\leq 3\times 10^{-12}$. It has been shown that axion haloscopes such as ORGAN are automatically sensitive to other kinds of dark matter candidates, such as dark photons, scalar field/dilaton dark matter, and exotic axion-electromagnetic couplings motivated by quantum electromagnetodynamics. We compute the exclusion limits placed on these various dark matter candidates by ORGAN 1a, and project sensitivity for some future ORGAN phases. In particular, the dark photon limits are the most sensitive to date in some regions of the parameter space.

description: Actia vitripennis Rondani, 1856
ORIGINAL DESCRIPTION: 1856: 60.
TYPE LOCALITY: “ Saint-Sauveur ” [France] (Robineau-Desvoidy 1830: 86) [type locality for Actia pilipennis Robineau-Desvoidy, 1830].
TYPE MATERIAL: see Remarks.
CURRENT STATUS: unjustified new replacement name for Actia lamia (Meigen, 1838) (Herting & Dely-Draskovits 1993: 329); junior synonym of Actia lamia (Meigen, 1838) (see Remarks).
REMARKS: Rondani’s (1856: 60) key for the genus Actia Robineau-Desvoidy, 1830 lists Actia vitripennis as its type species, but he did not provide a detailed description, type locality, number or sex of the specimens. Rondani (1859b: 19) moved the species Tachina pilipennis Fallén, 1810 to the genus Actia and proposed the replacement name Actia vitripennis for Actia pilipennis Robineau-Desvoidy, 1830 although Robineau-Desvoidy (1851: 186) recognised Roeselia lamia Meigen, 1838 as a junior synonym of Actia pilipennis (O’Hara et al. 1985: 93). Rondani (1861e: 152) provided specific characters to separate Actia vitripennis Rondani from Actia lamia (Meigen, 1838). Schiner (1864: 88) and Bezzi & Stein (1907: 389) considered Actia vitripennis as a junior synonym of Actia frontalis (Macquart, 1845), O’Hara et al. (1985: 93) and Herting & Dely-Draskovits (1993: 329) considered it as an unjustified new name for Roeselia lamia, but Rondani himself (1861e:152) considered Actia vitripennis as a valid species, different from Actia pilipennis Robineau-Desvoidy, 1830. The type material for Actia vitripennis will be the same as for the name it was proposed to replace, i. e., Actia pilipennis. There is no type of this latter species in the MNHN where Robineau-Desvoidy’s collection is preserved (Muséum national d’Histoire naturelle 2020). Under the name Actia vitripennis there is a female (non-type) in the MZUF.
