description: Recently, LHCb collaboration has confirmed the state $X(4140)$, with a much larger width $Γ= 83\pm 21^{+21}_{-14}$ MeV than the previous experimental measurements, which has confused the understanding of its nature. We have investigated the possibility of the $χ_{c1}(3P)$ interpretation for the $X(4140)$, considering the mass and the strong decay properties.

description: Erroneous— Thoracaster cylindratus Sladen, 1883   Reports for the Azores:
 Thoracaster cylindratus Sladen, 1883 —A.M. Clark & Downey 1992: 105–106, fig. 18f, pl. 26, figs. D–G.
 Type locality: between the Canaries and Cape Verde (22°18’N, 21°02’W).
 See: Madsen (1961: 82–92, figs. 10–11, pl. 5, pl. 6, figs. 1–7); A.M. Clark & Downey (1992).
 Occurrence: cosmopolitan, in the Atlantic, Pacific and Indian deep waters; in the West Atlantic from the Gulf of Mexico and the Caribbean, southwards to Brazil (A.M. Clark & Downey 1992); in the East Atlantic from SW of Ireland (Porcupine Seabight) southwards to off Liberia (Madsen 1961).
 Depth: 2,540(?2,315)– 5,990 m (A.M. Clark & Downey 1992).
 Habitat: soft bottoms, calcareous clay to Globigerina ooze (Madsen 1961).
 Remarks: A.M. Clark & Downey (1992) have listed the Azores under the geographical range of Thoracaster cylindratus. However, this species was never collected within the Azorean EEZ. Perrier (1885c, 1894) identified a specimen of this species (= Pseudaster cordifer) among the material collected by Talisman almost 500 km northeast of S„o Jorge Island (sta 134, 1883: 42°19’N, 23°36’W). Later, Koehler (1909) reported this species on two of Princesse Alice stations to the waters east and northeast of the Azores (sta 1306: 37°16’00”N, 20°11’45”W; sta 753: 39°50’00”N, 17°57’45”W). It is likely that T. cylindratus occurs in the Azores considering the wide distribution of this species in the Atlantic and the proximity of above mentioned records. The presence of this species within the archipelago’s waters, however, is still to be confirmed.

description: Fencing is a sport that relies heavily on the use of tactics. However, most existing methods for analyzing fencing data are based on statistical models in which hidden patterns are difficult to discover. Unlike sequential games, such as tennis and table tennis, fencing is a type of simultaneous game. Thus, the existing methods on the sports visualization do not operate well for fencing matches. In this study, we cooperated with experts to analyze the technical and tactical characteristics of fencing competitions. To meet the requirements of the fencing experts, we designed and implemented FencingVis, an interactive visualization system for fencing competition data.The action sequences in the bout are first visualized by modified bar charts to reveal the actions of footworks and bladeworks of both fencers. Then an interactive technique is provided for exploring the patterns of behavior of fencers. The different combinations of tactical behavior patterns are further mapped to the graph model and visualized by a tactical flow graph. This graph can reveal the different strategies adopted by both fencers and their mutual influence in one bout. We also provided a number of well-coordinated views to supplement the tactical flow graph and display the information of the fencing competition from different perspectives. The well-coordinated views are meant to organically integrate with the tactical flow graph through consistent visual style and view coordination. We demonstrated the usability and effectiveness of the proposed system with three case studies. On the basis of expert feedback, FencingVis can help analysts find not only the tactical patterns hidden in fencing bouts, but also the technical and tactical characteristics of the contestant.

description: The present thesis attempts an analysis of capital gains tax derived from the alienation of property. The new Income Tax Code (Law 4172/13), and in particular Articles 41 to 43, introduces the income from capital gains as a fourth category of income. The new regulations follow the Model Tax Convention on Income and on Capital of the Organisation for Economic Cooperation and Development (OECD), as analysed in Article 13 of the Convention. This thesis examines the provisions of Article 13 of the OECD Model Convention and the explanatory commentaries. In addition, it presents the implementation of capital gains tax in OECD countries and a historical overview of the tax in Greek tax system as the capital gains tax had been implemented in the past both in the alienation of immovable and movable property. Also, analyses the method of calculating capital gains tax on alienation of property assets and shares, the subject and the object of the tax, as well as the reductions and exemptions from it. Finally, it develops the relevant case-law of the European Court of Justice where the implementation of capital gains tax by Member States consist a violation of the principle of free movement of capital.

description: Evolution equations for leading twist operators in high orders of perturbation theory can be restored from the spectrum of anomalous dimensions and the calculation of the special conformal anomaly at one order less using conformal symmetry of QCD at the Wilson-Fisher critical point at non-integer $d=4-2ε$ space-time dimensions. In this work we generalize this technique to axial-vector operators. We calculate the corresponding three-loop evolution kernels in Larin's scheme and derive explicit expressions for the finite renormalization kernel that describes the difference to the vector case to restore the conventional ${\overline{\mathrm{MS}}}$-scheme. The results are directly applicable to deeply-virtual Compton scattering and the transition form factor $γ^*γ\toπ$.

description: I present a calculation of threshold soft-gluon corrections to single top quark production in ppbar collisions via all partonic processes in the t and s channels and via associated top quark and W boson production. The soft-gluon corrections are formally resummed to all orders, and finite-order expansions of the resummed cross section are calculated through next-to-next-to-next-to-leading order (NNNLO) at next-to-leading logarithmic (NLL) accuracy. Numerical results for single top quark production at the Tevatron are presented, including the dependence of the cross sections on the top quark mass and on the factorization and renormalization scales. The threshold corrections in the t channel are small while in the s channel they are large and dominant. Associated tW production remains relatively minor due to the small leading-order cross section even though the K factors are large.

description: Moiré superlattices have recently emerged as a novel platform where correlated physics and superconductivity can be studied with unprecedented tunability. Although correlated effects have been observed in several other moiré systems, magic-angle twisted bilayer graphene (MATBG) remains the only one where robust superconductivity has been reproducibly measured. Here we realize a new moiré superconductor, mirror symmetric magic-angle twisted trilayer graphene (MATTG) with dramatically richer tunability in electronic structure and superconducting properties. Hall effect and quantum oscillations measurements as a function of density and electric field allow us to determine the system's tunable phase boundaries in the normal state. Zero magnetic field resistivity measurements then reveal that the existence of superconductivity is intimately connected to the broken symmetry phase emerging from two carriers per moiré unit cell. Strikingly, we find that the superconducting phase gets suppressed and bounded at the van Hove singularities (vHs) partially surrounding the broken-symmetry phase, which is difficult to reconcile with weak-coupling BCS theory. Moreover, the extensive in situ tunability of our system allows us to achieve the ultra-strong coupling regime, characterized by a Ginzburg-Landau coherence length reaching the average inter-particle distance and very large $T_\mathrm{BKT}/T_{F}$ ratios in excess of 0.1, where $T_\mathrm{BKT}$ and $T_F$ are the Berezinskii-Kosterlitz-Thouless transition and Fermi temperatures, respectively. These observations suggest that MATTG can be electrically tuned close to the two-dimensional BCS-BEC crossover. Our results establish a new generation of tunable moiré superconductors with the potential to revolutionize our fundamental understanding and the applications of strong coupling superconductivity.

description: To improve device robustness, a highly desirable key feature of a competitive data-driven acoustic scene classification (ASC) system, a novel two-stage system based on fully convolutional neural networks (CNNs) is proposed. Our two-stage system leverages on an ad-hoc score combination based on two CNN classifiers: (i) the first CNN classifies acoustic inputs into one of three broad classes, and (ii) the second CNN classifies the same inputs into one of ten finer-grained classes. Three different CNN architectures are explored to implement the two-stage classifiers, and a frequency sub-sampling scheme is investigated. Moreover, novel data augmentation schemes for ASC are also investigated. Evaluated on DCASE 2020 Task 1a, our results show that the proposed ASC system attains a state-of-the-art accuracy on the development set, where our best system, a two-stage fusion of CNN ensembles, delivers a 81.9% average accuracy among multi-device test data, and it obtains a significant improvement on unseen devices. Finally, neural saliency analysis with class activation mapping (CAM) gives new insights on the patterns learnt by our models.

description: We combine the results from several HST investigations of the central structure of early-type galaxies to generate a large sample of parameterized surface photometry. The studies included were those that used the "Nuker law" to characterize the inner light distributions of the galaxies. The sample comprises WFPC1 and WFPC2 V band observations published earlier by our group, R band WFPC2 photometry of Rest et al., NICMOS H band photometry by Ravindranath et al. and Quillen et al., and the BCG WFPC2 I band photometry of Laine et al. The distribution of the logarithmic slopes of the central profiles strongly affirms that the central structure of elliptical galaxies with Mv < -19 is bimodal, based on both parametric and non-parametric analysis. At the HST resolution limit, most galaxies are either power-law systems, which have steep cusps in surface brightness, or core systems, which have shallow cusps interior to a steeper envelope brightness distribution. A rapid transition between the two forms occurs over the luminosity range -22 < Mv < -20, with cores dominating at the highest luminosities, and power-laws at the lowest. There are a few "intermediate" systems that have both cusp slopes and total luminosities that fall within the core/power-law transition, but they are rare and do not fill in the overall bimodal distribution of cusp slopes. These results are inconsistent with the Ferrarese et al. Virgo Cluster Survey (VCS) analysis. However, using galaxies common to the VCS samples, we demonstrate that the VCS models of the cusps are either a poor match to the observations or consist of forms fitted to the galaxy envelopes and extrapolated inward to the HST resolution limit.

description: We present a discussion of black 2-branes coupled to the fields of the universal hypermultiplet of ungauged N=2 supergravity theory in five dimensions. Using a general ansatz dependent on a spherically symmetric harmonic function, we show that there are exactly two such solutions, both of which can be thought of as arising from the dimensional reduction of either M2- or M5-branes over special Lagrangian cycles of a Calabi-Yau 3-fold, confirming previous results. By relaxing some of the constraints on the ansatz, we proceed to find a more general solution carrying both M-brane charges and discuss its properties, as well as its relationship to Euclidean instantons.

 Freyella benthophila Sladen, 1889 — Cherbonnier & Sibuet 1972: 388.
 Type locality: Pacific Ocean.
 See: Sladen (1889: 641–643, pl. 111, figs. 5–8); Downey (1986: 36–38, fig. 18); A.M. Clark & Downey (1992: 480, figs. 74a–b, pl. 112, figs. C–D).
 Occurrence: cosmopolitan deep-sea, in the Atlantic reported only to the east side, from the Bay of Biscay westwards to the Mid-Atlantic Ridge and to southern African waters (Cherbonnier & Sibuet 1972, Sibuet 1972, Downey 1986).
 Depth: 4,163 –5,000 m (Sibuet 1975, Downey 1986).
 Habitat: soft substrates (red clay; Sladen 1889).
 Remarks: Freyastera benthophila (Sladen, 1889) was reported in the Azores by Cherbonnier & Sibuet (1972), based on the material collected by Albatross during the Swedish Deep Sea Expedition. However, the original record mentioned a station half way between continental Europe and the Azores, as was referred by Downey (1986) and A.M. Clark & Downey (1992). Though it is likely that this cosmopolitan deep-water species will prove to occur within the Azorean EEZ, it needs to be confirmed by actual records.

description: A continuum-QRPA approach to calculation of the $2νββ$- and $0νββ$-amplitudes has been formulated. For $^{130}$Te a regular suppression (about 20%) of the high-multipole contributions to the $0νββ$-amplitude has been found which can be associated with additional ground state correlations appearing from the transitions to collective states in the continuum. At the same time the total calculated $0νββ$-amplitude for $^{130}$Te gets suppressed by about 20% as compared to the result of the usual, discretized, QRPA.

Helicity Observation of Weak and Strong Fields

description: We report in this letter our analysis of a large sample of photospheric vector magnetic field measurements. Our sample consists of 17200 vector magnetograms obtained from January 1997 to August 2004 by Huairou Solar Observing Station of the Chinese National Astronomical Observatory. Two physical quantities, $α$ and current helicity, are calculated and their signs and amplitudes are studied in a search for solar cycle variations. Different from other studies of the same type, we calculate these quantities for weak ($100G1000G$) fields separately. For weak fields, we find that the signs of both $α$ and current helicity are consistent with the established hemispheric rule during most years of the solar cycle and their magnitudes show a rough tendency of decreasing with the development of solar cycle. Analysis of strong fields gives an interesting result: Both $α$ and current helicity present a sign opposite to that of weak fields. Implications of these observations on dynamo theory and helicity production are also briefly discussed.

description: A quantum system subject to continuous measurement and post-selection evolves according to a non-Hermitian Hamiltonian. We show that, as one increases the rate of post-selection, this non-Hermitian Hamiltonian undergoes a spectral phase transition. On one side of this phase transition (for weak post-selection) an initially mixed density matrix remains mixed at all times, and an initially unentangled state develops volume-law entanglement; on the other side, an arbitrary initial state approaches a unique pure state with low entanglement. We identify this transition with an exceptional point in the spectrum of the non-Hermitian Hamiltonian, at which PT symmetry is spontaneously broken. We characterize the transition as well as the nontrivial steady state that emerges at late times in the mixed phase using exact diagonalization and an approximate, analytically tractable mean-field theory; these methods yield consistent conclusions.

 Freyella recta Koehler, 1907 a—Grieg 1932: 31; Mortensen 1927a: 122.
 Type locality: Mid-Atlantic Ridge (31°45’30”N, 42°42’30”W).
 See: Koehler (1909: 127–129, pl. 21, fig. 7, pl. 22, fig. 4, pl. 3, figs. 3–5); A.M. Clark & Downey (1992: 485–486, fig. 73).
 Occurrence: known with certainty from the type material collected only from the Mid-Atlantic Ridge (A.M. Clark & Downey 1992).
 Depth: 3,465 m (Koehler 1909).
 Habitat: soft bottoms (Globigerina ooze; Koehler 1909).
 Remarks: Freyella recta is known only with certainty from the type material (A.M. Clark & Downey 1992). This species was described by Koehler (1907a, 1909) based on a poorly preserved specimen taken by Princesse Alice in the Mid-Atlantic Ridge, about 600 miles southwest from the Azorean waters. Later reports from the archipelago by Mortensen (1927a) and Grieg (1932) erroneously placed the record of Princesse Alice cruise in the archipelago.

description: We introduce transfer learning for nonlinear dynamics, which enables efficient predictions of chaotic dynamics by utilizing a small amount of data. For the Lorenz chaos, by optimizing the transfer rate, we accomplish more accurate inference than the conventional method by an order of magnitude. Moreover, a surprisingly small amount of learning is enough to infer the energy dissipation rate of the Navier-Stokes turbulence because we can, thanks to the small-scale universality of turbulence, transfer a large amount of the knowledge learned from turbulence data at lower Reynolds number.

description: Hydrogen is rarely observed as ligand in hypervalent species, however, we find that high-pressure hydrogenation may stabilise hypervalent hydrogen-rich materials. Focussing on ternary silicon hydrides via lithium doping, we find anions composed of hypervalent silicon with H ligands formed under high pressure. Our results reveal two new hypervalent anions: layered-SiH$_{5}^{-}$ and tricapped trigonal prismatic SiH$_{6}^{2-}$. These differ from octahedral SiH$_{6}^{2-}$ described in earlier studies. In addition, there are further hydrogen-rich structures Li$_{3}$SiH$_{10}$ and Li$_{2}$SiH$_{6+δ}$ which may be stabilised at high pressure. Our work provides pointers to future investigations on hydrogen-rich materials.

Regulation of intracellular pH in cultured foetal rat hippocampal pyramidal neurones
Creators: name: Baxter, Keith Allen
Publisher: name: University of British Columbia
Year: 2009

description: The mechanisms regulating intracellular pH (pH[sub i]) were investigated in cultured foetal rat hippocampal pyramidal neurones loaded with the pH-sensitive fluorescent indicator 2',7'-bis(carboxyethyl)-5(or 6)-carboxyfluorescein. At room temperature (~20°C), steady-state pH[sub i] was 6.85 in the nominal absence of external HCO₃⁻, and increased to 7.15 in the presence of HCO₃⁻. In HCO₃⁻-free medium at 37°C, steady-state pH[sub i] rested at the substantially higher level of 7.23, whereas in HCO₃⁻ -containing solutions at 37°C, pH[sub i] was reduced to 7.13. Regardless of temperature and in the absence of HCO₃⁻, the removal of extracellular Na caused an immediate and sustained intracellular acidification, suggesting the dominance of a Na⁺-dependent mechanism(s) maintaining steady-state pH[sub i]. In HCO₃⁻/CO₂- buffered medium at room temperature, a moderate intracellular acidification was observed during the application of the anion exchanger inhibitor 4,4'-diisothiocyanatostilbene-2,2'-disulphonic acid (DIDS) or after the removal of HCO₃⁻, indicating the contribution of HCO₃⁻/CI- exchange to the maintenance of baseline pH[sub i]. Moreover, this anion exchanger could participate in pH[sub i] regulation even in the absence of extracellular Na⁺. At 37°C, however, DIDS did not alter steady-state pH[sub i] in the presence of HCO3-. Though extremely sensitive to the removal of extracellular Na⁺ at both temperatures, neither steady-state pH[sub i] nor the rate of pH[sub i], restoration from an imposed acid load were influenced by the application of ethylisopropylamiloride, a potent inhibitor of Na⁺/H+ exchange. Following an NH4+ -induced intracellular acidification, the rate of pH[sub i] recovery to baseline levels was faster at 37°C than at room temperature. Furthermore, in contrast to experiments performed at room temperature, the addition of HCO₃⁻ to the perfusate did not increase the rate of pH[sub i] recovery at 37°C. The results of this study suggest that at 37°C, the dominant regulator of pH[sub i] in hippocampal neurones is a Na⁺-dependent, HCO₃⁻-independent acid extrusion mechanism (probably an amiloride insensitive variant of the Na⁺/H+ exchanger). At room temperature, this Na⁺-dependent acid extrusion mechanism remains active, but the regulation of pH[sub i] appears to be supplemented by the activity of a Na⁺-independent HCO₃⁻/CI- exchanger.

description: There have been considerable research efforts devoted to quantum simulations of Fermi-Hubbard model with ultracold atoms loaded in optical lattices. In such experiments, the antiferromagnetically ordered quantum state has been achieved at half filling in recent years. The atomic lattice away from half filling is expected to host d-wave superconductivity, but its low temperature phases have not been reached. In a recent work, we proposed an approach of incommensurate quantum adiabatic doping, using quantum adiabatic evolution of an incommensurate lattice for preparation of the highly correlated many-body ground state of the doped Fermi-Hubbard model starting from a unit-filling band insulator. Its feasibility has been demonstrated with numerical simulations of the adiabatic preparation for certain incommensurate particle-doping fractions, where the major problem to circumvent is the atomic localization in the incommensurate lattice. Here we carry out a systematic study of the quantum adiabatic doping for a wide range of doping fractions from particle-doping to hole-doping, including both commensurate and incommensurate cases. We find that there is still a localization-like slowing-down problem at commensurate fillings, and that it becomes less harmful in the hole-doped regime. With interactions, the adiabatic preparation is found to be more efficient for that interaction effect destabilizes localization. For both free and interacting cases, we find the adiabatic doping has better performance in the hole-doped regime than the particle-doped regime. We also study adiabatic doping starting from the half-filling Mott insulator, which is found to be more efficient for certain filling fractions.

 See: Agassiz (1881); Mortensen (1951b: 362–362, figs. 168–169, pl. 26, figs. 4–6, pl. 41, figs. 12, 13, 15).
 Occurrence: known only from a specimen collected in Brazilian waters.
 Depth: 640 m.
 Habitat: soft substrates (mud).
 Remarks: in the batch of the original description of Anabrissus damesi (= Brissus damesi), Agassiz (1881) included a specimen from Faial Island (H.M.S. Challenger, sta. 75: 38°37’N, 28°30’W, 92–824 m), which was described by H.L. Clark (1925) as a very small juvenile form (<10 mm) with no petals and no genital pores. The animal lacked important diagnostic characters and was later considered as unidentifiable by Mortensen (1951b). Thus, the presence of this species in the archipelago is still to be confirmed and the known material of this species is still restricted to the type material from Brazil waters.

description: Αντικείμενο της παρούσας εργασίας είναι το ένδικο βοήθημα της αίτησης ακύρωσης διαδικασίας (άρθρο 341 ΚΠΔ). Το ένδικο αυτό βοήθημα δίνεται στον κατηγορούμενο που για λόγους ανώτερης βίας ή άλλα ανυπέρβλητα αίτια δεν κατάφερε να γνωστοποιήσει στο δικαστήριο το ανυπέρβλητο κώλυμα εμφάνισής του στη δίκη και να ζητήσει αναβολή, με αποτέλεσμα να δικαστεί ερήμην. Με το ένδικο αυτό βοήθημα, ο ανυπαιτίως ερημοδικασθείς κατηγορούμενος μπορεί να ζητήσει την ακύρωση της ερήμην καταδικαστικής σε βάρος του απόφασης, ώστε να δικαστεί και πάλι, κατ’ αντιμωλία, και να εκφράσει τις απόψεις του. Η αίτηση στρέφεται κατά ερήμην καταδικαστικής απόφασης, εφόσον ο καταδικασθείς είχε κλητευθεί ως γνωστής διαμονής (άρθρο 155 ΚΠΔ). Η αίτηση ακύρωσης διαδικασίας στηρίζεται στο γενικό κανόνα «ουδείς υποχρεούται στα αδύνατα» (impossibilium nulla est obligatio) και αποσκοπεί στην παροχή δυνατότητας επανορθώσεως ενδεχόμενης αδικίας σε βάρος του κατηγορουμένου που οφείλεται σε ανυπαίτια ερημοδικία του.
description: Object of this thesis is the petition for annulment of criminal proceedings (Article 341 CCP). This legal remedy is given to the defendant who, for reasons of force majeure or other causes insurmountable failed to notify the court about an insurmountable obstacle concerning his appearance to the trial and request an adjournment, so be tried in absentia. By this legal remedy, the defendant who has been condemned by default may request the annulment of the verdict of guilt in order to trial again, adversarial, and express his views. The petition is lodged against absentia conviction, if the accused was summoned as known residence (Article 155 CCP). The petition for annulment of criminal proceeding is based on the general rule «impossibilium nulla est obligation», and is designed to provide opportunity to rectify any injustice in against the defendant due to no fault of default.

description: We observe that in many F-theory models, tuning a specific gauge group $G$ and matter content $M$ under certain circumstances leads to an automatic enhancement to a larger gauge group $G' \supset G$ and matter content $M' \supset M$. We propose that this is true for any theory $G, M$ whenever there exists a containing theory $G', M'$ that cannot be Higgsed down to $G, M$. We give a number of examples including non-Higgsable gauge factors, nonabelian gauge factors, abelian gauge factors, and exotic matter. In each of these cases, tuning an F-theory model with the desired features produces either an enhancement or an inconsistency, often when the associated anomaly coefficient becomes too large. This principle applies to a variety of models in the apparent 6D supergravity swampland, including some of the simplest cases with U(1) and SU(N) gauge groups and generic matter, as well as infinite families of U(1) models with higher charges presented in the prior literature, potentially ruling out all these apparent swampland theories.

description: The inward flow of matter through accretion disks is driven by MHD turbulence. Global general relativistic MHD simulations shed quantitative light on this process, revealing a number of aspects of accretion previously unrecognized. Among them are strong stresses in the marginally stable and plunging regions near the black hole and electromagnetically-dominated conical relativistic jets that can form spontaneously from the accretion flow. The energy release associated with both of these effects can significantly augment the classical energy-release estimates based on purely hydrodynamic models.

 Type locality: African west coast (Setté Cama, Gabon).
 See: Mortensen (1910, 1935); Koehler (1914b).
 Occurrence: East Atlantic, Western tropical Africa from Cape Blanc to the Gulf of Guinea and Angola (Koehler 1914b, Mortensen 1925).
 Depth: shallow water (Koehler 1914b).
 Remarks: on erecting Arbaciella elegans, Mortensen (1910) observed the striking resemblance with young Arbacia species, particularly A. lixula and A. lixula africana, similar enough to cast doubts about the validity of this species (see also Mortensen 1935). Size at first sex maturity (presence of open gonopores), gross morphology, and colouration (which is strikingly colourful in comparison to that of juveniles of A. lixula) were the main features used to differentiate this taxon. Revising Azorean material (Museu Bocage—Natural History Museum, Lot no. 20743, Ponta Delgada harbour, S„o Miguel Island) identified by Marques (1980) as Arbaciella elegans, Kroh et al. (2011) employed genetic tools and re-visited the ontogenic development of Arbacia lixula. They found that A. lixula juveniles (the identity of which was confirmed by DNA analysis) are identical in morphology to what previous authors (e.g., Gautier-Michaz 1955, 1958; Molinier & Picard 1956; Regis 1982) have considered as Arbaciella elegans in the Mediterranean and the northeastern Atlantic. Kroh et al. (2011) thus rejected the records of the Arbaciella elegans from these areas (including the Azores) as misidentifications of juveniles of A. lixula, reducing the distribution of Arbaciella elegans to its type area (tropical West African coasts). In addition, they cautioned that Arbaciella elegans as such may not be a distinct taxon and that it might turn out that all Arbaciella are juvenile Arbacia specimens (in the case of West Africa of A. lixula africana) upon DNA-analysis of material from the type region.
