description: We study quasinormal spectrum of massive scalar field in the $D$-dimensional black hole background. We found the qualitatively different dependence on the field mass of the fundamental modes for $D\geq6$. The behaviour of higher modes is qualitatively the same for all $D$. Thus for some particular values of mass (of the field and of the black hole) the spectrum has two dominating oscillations with a very long lifetime. Also we show that the asymptotically high overtones do not depend on the field mass. In addition, we present the generalisation of the Nollert improvement of the continued fraction technique for the numerical calculation of quasi-normal frequencies of $D$-dimensional black holes.

description: Genus Bougainvillia Lesson, 1830
 Bougainvillia Lesson, 1830: 118.
 Type species. Bougainvillia macloviana Lesson, 1830, by monotypy.
 Diagnosis. Bougainvilliid hydroids sometimes stolonal but usually erect and irregularly branched, arising from a creeping hydrorhiza. Erect colonies with monosiphonic or polysiphonic hydrocaulus. Perisarc filmy or firm, covering hydrorhiza, hydrocauli, hydrocladia, and pedicels, terminating near hydranth bases or forming a pseudohydrotheca, not enveloping bases of tentacles. Hydranths club-shaped to fusiform; tentacles filiform, amphicoronate, in a distal whorl; hypostome conical to dome-shaped.
Gonophores predominantly free medusae, exceptionally as eumedusoids, borne singly or in clusters on hydrocauli, hydrocladia, pedicels, or hydrorhiza. Medusae bell-shaped; manubrium short; oral tentacles four, perradial, usually branched dichotomously; radial canals four; tentacle bulbs four; marginal tentacles all filiform, clustered on tentacle bulbs; ocelli usually present; gonads on manubrium; medusa buds sometimes produced.
 Remarks. Species of Bougainvillia Lesson, 1830 occur worldwide. Their hydroids can be difficult to identify, often resembling one another in colony form and varying in morphology under different environmental conditions (Vannucci & Rees 1961). One species of the genus is known to occur in Hawaii.

description: The problem of the quantum-limited or intrinsic linewidth of a good-cavity laser is revisited. Starting from the Scully-Lamb master equation, we present a fully analytical treatment to determine the correlation function and the spectrum of the cavity field at steady state. For this purpose, we develop an analytical approximation method that implicitly incorporates the microscopic fluctuations of both the phase and intensity of the field, and, in addition, takes full account of the saturation of the nonlinear gain. Our main result is a simple formula for the quantum-limited linewidth that is valid from near to far above threshold and also includes the presence of thermal photons. Close to the threshold, the linewidth is twice as large as predicted by the standard phase-diffusion treatment neglecting intensity fluctuations, and even 50% above threshold the increase is still considerable. In general, quantum fluctuations of the intensity are present and continue to influence the linewidth as long as the photon-number distribution is not strictly Poissonian. This inherent relationship is displayed by a formula relating the linewidth and the Mandel Q-parameter. More than 100% above treshold the linewidth is found to be smaller than predicted by the standard treatment, since the simple phase-diffusion model increasingly overestimates the rate of phase fluctuations by neglecting gain saturation. In the limit of a very large mean photon number the expected perfectly coherent classical field is obtained.

After a short introduction on the main aspects of the quantum gravitational optics, as a nontrivial example, we study this effect in the background of NUT space characterizing the spacetime of a spherical mass endowed with a gravitomagnetic monopole charge, the so called NUT factor.

description: In den 1720er-Jahren schrieb die Gräfin Luise Charlotte von Schwerin ihre Lebenserinnerungen nieder. Diese berichten in großem Detail von ihrem Leben und ihrem Übertritt vom reformierten zum katholischen Glauben im Jahr 1719 in Wien und geben einen für diese Zeit einzigartigen Einblick in die Lebenswelt einer Frau, die daraufhin aus Preußen verstoßen wurde und sich eine neue Existenz aufbauen musste. In ihren Memoiren zeichnet sie ein außergewöhnlich präzises Bild von Handlungsspielräumen und Netzwerken von Frauen im frühen 18. Jahrhundert. Im Rahmen eines vom FWF finanzierten Forschungsprojekts wird eine digitale Edition entstehen, die den Text in französischer Sprache und deutscher Übersetzung für die Forschung zugänglich macht und durch Hintergrundinformationen erschließt. Das Poster wird insbesondere auf die angewandten Methoden und erste Ergebnisse des Projekts eingehen sowie das Datenmodell vorstellen, mit besonderem Fokus auf soziale Beziehungen.

description: We study in detail the existence, nonexistence and behavior of global minimizers, ground states and corresponding energy levels of the $(p,q)$-Laplace equation $-Δ_p u -Δ_q u = α|u|^{p-2}u + β|u|^{q-2}u$ in a bounded domain $Ω\subset \mathbb{R}^N$ under zero Dirichlet boundary condition, where $p > q > 1$ and $α, β\in \mathbb{R}$. A curve on the $(α,β)$-plane which allocates a set of the existence of ground states and the multiplicity of positive solutions is constructed. Additionally, we show that eigenfunctions of the $p$- and $q$-Laplacians under zero Dirichlet boundary condition are linearly independent.

description: Genus Amphinema Haeckel, 1879
 Amphinema Haeckel, 1879: 49.
 Type species. Oceania dinema Péron & Lesueur, 1810 [Amphinema dinema], by subsequent designation by Rees & Russell (1937).
 Diagnosis. Pandeid hydroids stolonal (unless Bimeria biscayana Browne, 1907 is included; see Schuchert 2007), arising from a creeping hydrorhiza. Hydrocaulus simple, slender, of moderate length, often annulated basally, gradually expanding in diameter distally. Perisarc covering hydrorhiza and hydrocaulus, terminating below hydranth base; pseudohydrotheca absent. Hydranths clavate; tentacles filiform, amphicoronate, eight or more, in a distal whorl; hypostome dome-shaped.
Gonophores free medusae; medusa buds borne on short pedicels arising from hydrorhiza, or caulus, or both. Medusae bell-shaped, usually with large apical process, gastric peduncle absent; manubrium broad at base; oral lips four, simple, little or not crenulated; mesenteries between manubrium and radial canals present or absent; radial canals four; marginal tentacles two, opposite, perradial, large; tentaculae or marginal warts present or absent; ocelli present or absent; gonads adradial, interradial, or perradial, sometimes extending onto radial canals.
 Remarks. The genus Amphinema Haeckel, 1879 was founded for two nominal species, Saphenia titania Gosse, 1853 and S. apicata McCrady, 1859. Both are now generally included in the synonymy of Oceania dinema Péron & Lesueur, 1810 (= Amphinema dinema) (Mayer 1910a; Russell 1953; Kramp 1961; Schuchert 2007). However, Haeckel’s (1879) account of S. titania was evidently based in part on a species not described until later, Stomotoca rugosa Mayer, 1900a (= Amphinema rugosum) (Rees & Russell 1937; Russell 1953).
 Some misinformation exists in the literature about the type species of Amphinema. Rees & Russell (1937: 70) stated that Haeckel (1879) had fixed Amphinema titania as “genotype,” but Haeckel in fact did not designate a type species for the genus. After providing a new definition of Amphinema, Rees & Russell (1937: 70) chose A. dinema as type species. Their designation is valid because (1) no previous type species designation exists for the genus (ICZN Art. 69.1), and (2) O. dinema was included in Amphinema by Haeckel (1879) as a synonym of A. titania (ICZN Art. 67.2). This type fixation has been accepted as valid by authors including Russell (1953), Kramp (1961), and Schuchert (2007).

description: Recently proposed implementations of quantum computer suffer from unavoidable interaction between quantum bits depending upon data being written in them. Novel procedure of avoiding multiqubit errors arising due to uncontrollable qubit-qubit interaction by using addititonal intermediate qubits is proposed. It is shown that the scheme requires only polynomial increase in number of qubits and algorithmic steps.

Influence of round-off errors on the reliability of numerical simulations of chaotic dynamic systems

description: We illustrate that, like the truncation error, the round-off error has a significant influence on the reliability of numerical simulations of chaotic dynamic systems. Due to the butterfly-effect, all numerical approaches in double precision cannot give a reliable long-term simulation of chaotic dynamic systems. So, in order to avoid man-made uncertainty of numerical simulations of chaos, we had to greatly decrease both of the truncation and round-off error to a small enough level, plus a verification of solution reliability by means of an additional computation using even smaller truncation and round-off errors.

description: We consider the complete Euler system describing the time evolution of a general inviscid compressible fluid. We introduce a new concept of measure-valued solution based on the total energy balance and entropy inequality for the physical entropy without any renormalization. This class of so-called dissipative measure-valued solutions is large enough to include the vanishing dissipation limits of the Navier-Stokes-Fourier system. Our main result states that any sequence of weak solutions to the Navier-Stokes-Fourier system with vanishing viscosity and heat conductivity coefficients generates a dissipative measure-valued solution of the Euler system under some physically grounded constitutive relations. Finally, we discuss the same asymptotic limit for the bi-velocity fluid model introduced by H.Brenner.
Periodic Optical Outbursts from the Be/Neutron Star Binary AX J0049.4-7323

description: The optical light curve of the Be/neutron star binary AX J0049.4-7323 has been investigated using data from the MACHO and OGLE-II projects. This X-ray source, whose neutron star has a very slow rotation rate (P_pulse=755.5 sec), shows optical outbursts every 394 days. The regularity of these outbursts suggests that their recurrence time is the orbital period of the system. During the outbursts the system brightens and becomes slightly redder. A possible interpretation is that a portion of the equatorial disk is excited as the neutron star passes through it during periastron passage. In the intervals between outbursts the light curve shows 11-day quasi-periodic varability which may be associated with the rotation of the Be star's extended disk.

description: Despite their potential to exceed the theoretical Shockley-Queisser limit, ferroelectric photovoltaics (FPVs) have performed inefficiently due to their extremely low photocurrents. Incorporating Bi2FeCrO6 (BFCO) as the light absorber in FPVs has recently led to impressively high and record photocurrents [Nechache et al. Nature Photon. 2015, 9, 61], reviving the FPV field. However, our understanding of this remarkable phenomenon is far from satisfactory. Here, we use first-principles calculations to determine that such excellent performance mainly lies in the efficient separation of electron-hole (e-h) pairs. We show that photoexcited electrons and holes in BFCO are spatially separated on the Fe and Cr sites, respectively. This separation is much more pronounced in disordered BFCO phases, which show exceptional PV responses. We further set out to design a strategy for next-generation FPVs, not limited to BFCO, by exploring 44 additional Bi-based double-perovskite oxides. We suggest 9 novel active-layer materials that can offer strong e-h separations and a desired band gap energy for application in FPVs. Our work indicates that charge separation is the most important issue to be addressed for FPVs to compete with conventional devices.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

 Type species. Hydrichthys mirus Fewkes, 1887, by monotypy.
 Diagnosis. Pandeid hydroids with colonies ectoparasitic on fishes and on ichthyoparasitic copepods. Zooids monomorphic or dimorphic, atentaculate, clavate to tubular, arising from a basal encrusting plate or reticular hydrorhiza; perisarc absent.
 FIGURE 12. Amphinema sp.: hydrocaulus and hydranth, ROMIZ B3824. Scale equals 0.5 mm.

Gonophores fixed sporosacs or free medusae, arising from hydranths or from gonostyles. Medusae, when present, with bell-shaped umbrella having an apical projection. Manubrium cruciform in cross-section; mouth with four prominent lips; radial canals jagged, four or more; mesenteries present. Newly liberated medusae with two opposite marginal tentacles; older medusae with up to six; tentacle bulbs conical. Gonads on interradii of manubrium, forming eight adradial masses. Ocelli absent.
 Remarks. Diagnosis of the polyphyletic genus Hydrichthys Fewkes, 1887 as given here follows that in Bouillon et al. (2006) and Schuchert (2007). Bouillon et al. recognized seven species in this genus of parasitic hydroids, including Hydrichthys pietschi Martin, 1975 from Hawaii.
 Hydroid species currently assigned to Hydrichthys are known to liberate medusae referable to several genera (Schuchert 2007), and the genus is in need of revision.

description: Restrictions of incidence-preserving path maps produce an oriented hypergraphic All Minors Matrix-tree Theorems for Laplacian and adjacency matrices. The images of these maps produce a locally signed graphic, incidence generalization, of cycle covers and basic figures that correspond to incidence-k-forests. When restricted to bidirected graphs the natural partial ordering of maps results in disjoint signed boolean lattices whose minor calculations correspond to principal order ideals. As an application, (1) the determinant formula of a signed graphic Laplacian is reclaimed and shown to be determined by the maximal positive-circle-free elements, and (2) spanning trees are equivalent to single-element order ideals.

description: A Brownian ratchet is a one-dimensional diffusion process that drifts toward a minimum of a periodic asymmetric sawtooth potential. A flashing Brownian ratchet is a process that alternates between two regimes, a one-dimensional Brownian motion and a Brownian ratchet, producing directed motion. These processes have been of interest to physicists and biologists for nearly 25 years. The flashing Brownian ratchet is the process that motivated Parrondo's paradox, in which two fair games of chance, when alternated, produce a winning game. Parrondo's games are relatively simple, being discrete in time and space. The flashing Brownian ratchet is rather more complicated. We show how one can study the latter process numerically using a random walk approximation.

 Merga Hartlaub, 1913: 249.
 Type species. Pandea violacea A. Agassiz & Mayer, 1899 [Merga violacea], by monotypy.
 Diagnosis. Pandeid hydroids stolonal or with small, erect, and slightly branched cormoids, arising from a creeping hydrorhiza. Erect colonies with monosiphonic hydrocaulus. Perisarc filmy to firm, covering hydrorhiza, hydrocauli, hydrocladia, and pedicels, terminating near hydranth base or forming a pseudohydrotheca, not enveloping bases of tentacles. Hydranths club-shaped to fusiform; tentacles filiform, amphicoronate, in a distal whorl; hypostome conical to dome-shaped.
Gonophores where known free medusae, borne on hydrocauli or hydrorhiza. Medusae bell-shaped, with or without apical process; manubrium of moderate length, not twisted, cruciform in cross-section at base, perradial edges with mesenteries extending to radial canals, oral lips four, simple to slightly folded; radial canals four; marginal tentacles four, eight, or more, all filiform; rudimentary tentacle bulbs and tentaculae present or absent; ocelli present or absent; gonads adradial or interradial, smooth or granulate, on manubrium, not located on folds or pits of manubrial wall.
 Remarks. Hartlaub (1913) established Merga to accommodate Pandea violacea A. Agassiz & Mayer, 1899, a pandeid medusa having gonads without folds. By mid-20 th century four species were included in the genus (Kramp 1961: 106–107, 444), and the number is currently nine (Schuchert 2009). Most are known only as the medusa stage. Where described, hydroids are small and have few distinguishing morphological characters. The genus Merga has been reviewed and revised a number of times, most recently by Schuchert (1996, 2007) and Brinckmann-Voss & Arai (1998).

description: A possibility to produce entangled superpositions of strong coherent states is discussed. A recent proposal by Howell and Yazell [Phys. Rev. A 62, 012102 (2000)] of a device which entangles two strong coherent coherent states is critically examined. A serious flaw in their design is found. New modified scheme is proposed and it is shown that it really can generate non-classical states that can violate Bell inequality. Moreover, a profound analysis of the effect of losses and decoherence on the degree of entanglement is accomplished.

description: With quantum computers of significant size now on the horizon, we should understand how to best exploit their initially limited abilities. To this end, we aim to identify a practical problem that is beyond the reach of current classical computers, but that requires the fewest resources for a quantum computer. We consider quantum simulation of spin systems, which could be applied to understand condensed matter phenomena. We synthesize explicit circuits for three leading quantum simulation algorithms, employing diverse techniques to tighten error bounds and optimize circuit implementations. Quantum signal processing appears to be preferred among algorithms with rigorous performance guarantees, whereas higher-order product formulas prevail if empirical error estimates suffice. Our circuits are orders of magnitude smaller than those for the simplest classically-infeasible instances of factoring and quantum chemistry.

description: Modulo a homogeneous degree of freedom and a global constraint, the linearly polarised Gowdy $T^3$ cosmologies are equivalent to a free scalar field propagating in a fixed nonstationary background. Recently, a new field parameterisation was proposed for the metric of the Gowdy spacetimes such that the associated scalar field evolves in a flat background in 1+1 dimensions with the spatial topology of $S^1$, although subject to a time dependent potential. Introducing a suitable Fock quantisation for this scalar field, a quantum theory was constructed for the Gowdy model in which the dynamics is implemented as a unitary transformation. A question that was left open is whether one might adopt a different, nonequivalent Fock representation by selecting a distinct complex structure. The present work proves that the chosen Fock quantisation is in fact unique (up to unitary equivalence) if one demands unitary implementation of the dynamics and invariance under the group of constant $S^1$ translations. These translations are precisely those generated by the global constraint that remains on the Gowdy model. It is also shown that the proof of uniqueness in the choice of complex structure can be applied to more general field dynamics than that corresponding to the Gowdy cosmologies.

description: A new ephemeris has been determined for the supersoft X-ray binary CAL 83 using MACHO photometry. With an improved orbital period of 1.047568 days, it is now possible to phase together photometric and spectroscopic data obtained over the past two decades with new far ultraviolet spectra taken with FUSE. We discuss the properties of the orbital and longterm optical light curves as well as the colors of CAL 83. In the far ultraviolet the only well-detected stellar feature is emission from the O VI resonance doublet. The radial velocity of this emission appears to differ from that of HeII in the optical region, although we only have partial phase coverage for the O VI line. The FUSE continuum variations are similar to the optical light curve in phase and amplitude.

description: Family Balellidae Stechow, 1922  Tubidendridae Nutting, 1905: 940.
Balellidae Stechow, 1922: 142.
 Diagnosis. Filiferan hydroids with erect, irregularly branched, polymorphic colonies. Hydrocaulus polysiphonic. Hydrorhiza, hydrocaulus, and hydrocladia covered with perisarc, although naked coenosarc may also be present. Gastrozooids club-shaped to pyriform; tentacles filiform, in two widely separated whorls, one proximally and another mid-distally on hydranth; hypostome elongate. Gonozooids small, slender, with one or no tentacles; bearing medusa buds. Dactylozooids present on hydrocaulus and hydrocladia, digitate, solid, lacking perisarc over most or all of length.
Gonophores free medusae, borne on gonozooids; radial canals four; marginal tentacles four, solitary, short.
 Remarks. The name Tubidendridae, first applied to this family by Nutting (1905), is not available [ICZN Art. 11.7.1.1] because it was not formed from the stem of an available generic name included in the taxon when it was established (Calder 1988). It was replaced by the name Balellidae by Stechow (1922).
 Affinities and classification of Balellidae have been difficult to resolve because little is known about the life cycle in species of the group. Jäderholm (1919) and Schuchert (2003) established the presence of medusa buds arising from gonozooids in Balella mirabilis (Nutting, 1905), but the adult medusa has yet to be described. Gonophores have not been observed in the only other putative species in the family, B. irregularis (Fraser, 1938a). Stechow (1923b) included the taxon as a subfamily of Clavidae McCrady, 1859, while authors including Millard (1975), Hirohito (1988), and Bouillon (1995) included it in Bougainvilliidae Lütken, 1850. Calder (1988) regarded it as a distinct family, closer to Clavidae [now Oceaniidae Eschscholtz, 1829] than to Bougainvilliidae. Recent authors have also recognized it as a distinct family (Calder et al. 2003; Schuchert 2003; Bouillon et al. 2006). Schuchert (2003), and Nutting (1905) earlier, suggested that affinities of the family were with Hydractiniidae L. Agassiz, 1862, given the polymorphic character of zooids and the occurrence of naked coenosarc on stems of both B. mirabilis and B. irregularis.
 Balellidae includes the single genus Balella Stechow, 1919, and two species.

description: This paper is devoted to investigate the teleparallel versions of the Friedmann models as well as the Lewis-Papapetrou solution. We obtain the tetrad and the torsion fields for both the spacetimes. It is shown that the axial-vector vanishes for the Friedmann models. We discuss the different possibilities of the axial-vector depending on the arbitrary functions $ω$ and $ψ$ in the Lewis-Papapetrou metric. The vector related with spin has also been evaluated.

description: Das Proposal beschreibt die Charters Encoding Initiative (CEI) und ihre Bedeutung für die Standardisierung der XML-Kodierung historischer Urkunden. Es hebt die Einschränkungen des Schemas hervor und argumentiert für eine Transformation in das flexiblere TEI-P5-Format, um die Interoperabilität zu verbessern. Das Projekt zielt darauf ab, die gesamte XML-Datenbank von Monasterium.net für den Einsatz in einem KI-gestützten Virtual Research Environment vorzubereiten. Es werden neue Workflows entwickelt und bestehende erweitert. Zusätzlich werden verschiedene Methoden zur Validierung und Normalisierung der Daten eingesetzt. Der iterative Ansatz ermöglicht es, Probleme zu identifizieren und zu beheben, um einen genauen Transfer zu gewährleisten. Die methodische Innovation wird u. a. durch die Verwendung datengetriebener Textauszeichnungsanalyse und statistischer String-Ähnlichkeitsmessungen erreicht. Mehrwert bringt außerdem die langfristige Nutzbarkeit der Daten für die wissenschaftliche Gemeinschaft. Das Projekt fördert die dauerhafte Erhaltung und verbesserte Zugänglichkeit mittelalterlicher und frühneuzeitlicher Urkunden in digitaler Form.

Homoclinic chaos and energy condition violation

description: In this letter we discuss the connection between so-called homoclinic chaos and the violation of energy conditions in locally rotationally symmetric Bianchi type IX models, where the matter is assumed to be non-tilted dust and a positive cosmological constant. We show that homoclinic chaos in these models is an artifact of unphysical assumptions: it requires that there exist solutions with positive matter energy density $ρ>0$ that evolve through the singularity and beyond as solutions with negative matter energy density $ρ<0$. Homoclinic chaos is absent when it is assumed that the dust particles always retain their positive mass.In addition, we discuss more general models: for solutions that are not locally rotionally symmetric we demonstrate that the construction of extensions through the singularity, which is required for homoclinic chaos, is not possible in general.

description: It has recently been suggested that various entanglement measures for bipartite mixed states do not in general give the same ordering even in the asymptotic cases [S. Virmani and M. B. Plenio, Phys. Lett. A {\bf 268}, 31 (2000)]. That is, for two certain mixed states, the order of the degree of entanglement depends on the measures. Therefore, incomparable pairs of mixed states which cannot be transformed to each other with unit efficiency by any combinations of local quantum operations and classical communications exist. We make an analogy of the relativity of the order of the degree of entanglement to the relativity of temporal orders in the special theory of relativity.

description: Genus Hydrodendrium Nutting, 1905
 Hydrodendrium Nutting, 1905: 936.
 Nuttingia Stechow, 1909: 10 [invalid replacement name for Hydrodendrium Nutting, 1905].
 Type species. Hydrodendrium gorgonoides Nutting, 1905, by monotypy.
 Diagnosis. Hydractiniid hydroids with erect colonies, comprising a massive, arborescent, spongy, branched hydrocaulus with a skeletal axis of intertwining and anastomosing chitinous fibres penetrated internally and invested externally by naked coenosarc; spines and hydrophores absent. Hydranths monomorphic, sessile, naked, anemone-like, arising from bands of coenosarc at surface, not embedded in skeleton; tentacles filiform, in a single distal whorl; hypostome flattened to dome-like.
Gonophores fixed sporosacs, arising as sac-shaped evaginations of hydranth body wall; colonies monoecious.
 Remarks. Hydrodendrium Nutting, 1905 has seldom been used as a valid genus name. Stechow (1909) instituted Nuttingia as a replacement name for it after incorrectly considering Hydrodendrium a homonym of Hydrodendron Hincks, 1874 (see also Stechow 1923b). The two are not homonyms (ICZN Art. 56), and Nuttingia is an invalid junior objective synonym of Hydrodendrium. Both Hydrodendrium and Nuttingia were included in the synonymy of Hydractinia Van Beneden, 1844a by authors including Bouillon (1985), Bouillon et al. (1997) and Schuchert (2008a).
 The genus Hydrodendrium is maintained here based on a unique combination of characters outlined in the diagnosis above. It is distinguished from Hydractinia in having monomorphic, stout hydranths with a low hypostome that arise from an erect and arborescent chitinous skeleton lacking spines, and gonophores that are fixed sporosacs arising as hernia-like protuberances from the walls of unmodified (Nutting 1905) or only slightly shrunken hydranths. The growth form of the skeletal axis superficially resembles that of Solanderia Duchassaing & Michelin, 1846 or even an octocoral.
 Hydrodendrium or its junior objective synonym Nuttingia have been assigned at various times to the families Hydrodendriidae Nutting, 1905 (Nutting 1905), Podocorynidae Allman, 1864 (Hickson & Gravely 1907), Bougainvilliidae Lütken, 1850 (Stechow 1909), Clathrozoidae Stechow, 1921a (Stechow 1921a), and Hydractiniidae L. Agassiz, 1862 (Bouillon et al. 1997). Affinities of the genus appear to be with Hydractiniidae, as noted by authors such as Schuchert (2008a).
