Leucopsila

description: Genus Leucopsila Dendy & Row, 1913
 TYPE SPECIES. — Leuconia stilifera Schmidt, 1870 by monotypy.
DIAGNOSIS. — Baeriidae in which the cortex is formed by tangential triactines and microdiactines. The choanoskeleton is composed almost exclusively of irregularly scattered giant tetractines, and numerous microdiactines. Both the cortical and atrial surfaces are covered by a dense layer of microdiactines. While in the cortex microdiactines overlay the continuous layer of tangential triactines, they are the sole skeleton of the exhalant aquiferous system.
DESCRIPTION
 Like Baeria, Leucopsila has a massive body, with an irregular leuconoid aquiferous system organized around exhalant canals that are distributed in the choanosome in the form of an anastomosing network. The organization of the skeleton is similar in Leucopsila stilifera (Schmidt, 1870) and Baeria johnstoni (Carter, 1871); the major distinction between the two being the replacement of pugioles in the skeleton of the exhalant system of Leucopsila by microdiactines.
 Leucopsila is a large sponge that has been reported only from arctic and subarctic waters, both from the Atlantic and Pacific regions (Schmidt 1870; Haeckel 1872; Hôzawa 1919).

description: A framework for higher gauge theory based on a 2-group is presented, by constructing a groupoid of connections on a manifold acted on by a 2-group of gauge transformations, following previous work by the authors where the general notion of the action of a 2-group on a category was defined. The connections are discretized, given by assignments of 2-group data to 1- and 2-cells coming from a given cell structure on the manifold, and likewise the gauge transformations are given by 2-group assignments to 0-cells. The 2-cells of the manifold are endowed with a bigon structure, matching the 2-dimensional algebra of squares which is used for calculating with 2-group data. Showing that the action of the 2-group of gauge transformations on the groupoid of connections is well-defined is the central result. The effect, on the groupoid of connections, of changing the discretization is studied, and partial results and conjectures are presented around this issue. The transformation double category that arises from the action of a 2-group on a category, as defined in previous work by the authors, is described for the case at hand, where it becomes a transtormation double groupoid. Finally, examples of the construction are given for simple choices of manifold: the circle, the 2-sphere and the torus.

 Gitognathus gibberosus Delucchi, 1955a: 68, 71. Holotype m, Hungary: Pest County, VaÂcz [VaÂc] (HNHM [examined]).
 Material. HOLOTYPE m (cr, left antenna and left fore wing lacking) labelled`VaÂcz. 914. BiroÂ. V.; 26.V. [back side of former label]; Sphaeripalpus [sic] gibberosus m. V. Delucchi det. m; TYPE [red]’. One slide (sc) labelled`3; B [circled] DIS antenne m Sphaeripalpus [sic] gibberosus m.’ with left antenna (1955a: 70, ®gure 92) and one slide (sc) labelled`4; B [circled] DIS ala m Sphaeripalpus [sic] gibberosus’ with left fore wing (1955a: 70, ®gure 91) of holotype.
 Remarks. Delucchi described the female and stated` Type deÂposeÂ au MuseÂum d’Histoire Naturelle de Budapest’ but did not specify the number of specimens he had. There are two females (cr) in VD which match the data cited (`Budapest BiroÂ. 1916’ and`A.-OrboÂ Dr SzilaÂdy’) but lack any original identi®cation label.
 Delucchi (1955a: 68) separated gibberosus from Sphaeripalpu s viridis FoÈrster [sub Gitognathus grandiclava Thomson] based on the ®rst funicular segment being longer than the pedicel, the petiole subtransverse, the transscutal articulation weakly sinuate, and the number of setae on the cubital fold reduced. Examination of many females and males of viridis and fuscipes from Northern and Central Europe (BMNH, ETHZ, LUZM, MG, MHNG, NMBE, RA, VD) showed that these characters do not hold good for separating the species. First, the length of funicular segments is variable even within a single species as shown by Graham (1969: 212) and my own investigations. Second, careful measurements have revealed that the petiole of the holotype is at least as long as broad (the length of the petiole was di cult to measure accurately, hence it may actually be slightly longer than broad). Third, the sinuation of the transscutal articulation and the number of setae on the cubital fold are not exceptional but fall within the range of viridis. As any other character, notably the almost completely reduced pilosity on the lower surface of the speculum, also ®t the diagnosis of the latter species very well, there is no reason to keep gibberosus separate.
 Status. Junior synonym of Sphaeripalpus viridis FoÈrster syn. n.

 TYPE SPECIES. — Eilhardia schulzei Poléjaeff, 1883 by monotypy.
DIAGNOSIS. — Calyciform Baeriidae with inhalant ostia on the inner surfaces, and oscula on the outer surfaces. The ostia-bearing surface is supported by a thin layer of tangential triactines and scattered microdiactines. The skeleton of the exhalant system and of the choanoskeleton is composed of large triactines and microdiactines. The cortical skeleton consists of giant longitudinal and small diactines as well as tangential triactines.
DESCRIPTION
 Eilhardia schulzei Poléjaeff, 1883 is quite an unusual calcareous sponge, with a calyciform body in which the inhalant surface is the inner one, and exhalant surface the outer one. Its internal organization is similar to other Baeriidae. Poléjaeff (1883) has given a very detailed description and beautiful illustration of this sponge.

description: (Abridged). The type-I X-ray bursting low mass X-ray binary KS 1731-260 was recently detected for the first time in quiescence by Wijnands et al., following an approximately 13 yr outburst which ended in Feb 2001. Unlike all other known transient neutron stars, the duration of this recent outburst is as long as the thermal diffusion time of the crust. The large amount of heat deposited by reactions in the crust will have heated the crust to temperatures much higher than the equilibrium core temperature. As a result, the thermal luminosity currently observed from the neutron star is dominated not by the core, but by the crust. Moreover, the level and the time evolution of quiescent luminosity is determined mostly by the amount of heat deposited in the crust during the most recent outburst. Using estimates of the outburst mass accretion rate, our calculations of the quiescent flux immediately following the end of the outburst agree with the observed quiescent flux to within a factor of a few. We present simulations of the evolution of the quiescent lightcurve for different scenarios of the crust microphysics, and demonstrate that monitoring observations (with currently flying instruments) spanning from 1--30 yr can measure the crust cooling timescale and the total amount of heat stored in the crust. These quantities have not been directly measured for any neutron star.

 Gitognathus nitidus Delucchi, 1955a: 68, 69. Holotype m, Germany: Bayern, Wolfratshausen (VD [examined]).
 Material. HOLOTYPE m (cp, wings and right fore leg beyond coxa lacking) labelled`333; Wolfratshausen (Baviera); leg. F. Groschke IV. 1950 V. Delucchi leg.; ex Phytomyza obscurella Fall. su Aegopodium; Stictomischus [sic] nitidus m. V. Delucchi det.; TYPE [red]’. One slide (sc) labelled`5; 333 Groschke nitidus m. Disegnato’ with left fore wing (stigma illustrated, 1955a: 70, ®gure 88) of holotype.
 Remarks. Holotype subsequently remounted from micro-pin by me.
 The species was transferred to Sphaeripalpus by Huang (1990b: 249) but belongs to Glyphognathus. The holotype is extremely close to G. convexus (Delucchi) with which it shares the deeply excised lower edge of the mandible and the large, subcircular stigma of the fore wing. It diOEers mainly by having the antenna about 1.45 times as long as breadth of head (1.31±1.40 in convexus for n 5 20 mm from England, Germany, Hungary, and Switzerland, BMNH, HNHM, MZL, NMBE, UMO, VD) and the pale femora (most often heavily infuscate at basal two thirds in convexus). Some specimens, e.g. a paratype of G. umbelliferae Graham [5 convexus], have even proved to be intermediate in both characters. With regard to the insu cient material at my disposition, however, I prefer to keep the two species separate. Further studies on more and reared material will be necessary to reveal a possible synonymy with certainty.
 Status. Glyphognathus (Glyphognathus) nitidus (Delucchi) comb. n.

description: P-Cygni type Lya profiles exhibited in nearly half of starburst galaxies, both nearby and high-z, are believed to be formed by an expanding supershell surrounding a star-forming region. We apply the Monte Carlo code which was developed previously for static and plane-parallel medium to calculate the Lya line transfer in a supershell of neutral hydrogen which are expanding radially in a spherical bulk flow. We consider typical cases that the supershell has the Lya line-centre optical depth of $τ_0=10^5-10^7$, a radial expansion velocity of $V_exp = 300 km/s, and the turbulence of b=40 km/s. We find that there appear a few emission peaks at the frequencies corresponding to (2N-1) V_exp, where the order of back scatterings N > 1. As V_exp -> b, the emergent profiles become similar to those for the static medium and the peaks are less prominent. We also investigate the effects of column density of the supershell on the emergent Lya profiles. We find that the number and the flux ratios of emission peaks are determined by interplay of $τ_0$ and V_exp of the supershell. We discuss the effects of dust extinction and the implication of our works in relation to recent spectroscopic observations of starburst galaxies.

Η Θήρα, ένα από τα κορυφαία διεθνή τουριστικά θέρετρα, είναι γνωστή για τα μοναδικά γεωμορφολογικά της χαρακτηριστικά. Ωστόσο, η ραγδαία τουριστική ανάπτυξη έχει προκαλέσει σημαντικά προβλήματα στην περιοχή, όπως ανεξέλεγκτη δόμηση και συγκρούσεις χρήσεων γης, επηρεάζοντας και τη περιοχή μελέτης (Δημοτικής Κοινότητας Επισκοπής Γωνιάς).

Η αναφορά στην ευρύτερη περιοχή είναι κρίσιμη, καθώς οι εξελίξεις και οι πολιτικές σε επίπεδο νησιού επηρεάζουν άμεσα τις δημοτικές κοινότητες και τους οικισμούς. Στη συνέχεια, αναλύονται τα Συστήματα Γεωγραφικών Πληροφοριών και περιγράφεται η μεθοδολογία δημιουργίας της βάσης δεδομένων.

description: We develop a generalized pseudofermion functional renormalization group (PFFRG) approach that can be applied to arbitrary Heisenberg models with spins ranging from the quantum case S=1/2 to the classical limit S→∞. Within this framework, spins of magnitude S are realized by implementing M=2S copies of spin-1/2 degrees of freedom on each lattice site. We confirm that even without explicitly projecting onto the highest spin sector of the Hilbert space, ground states tend to select the largest possible local spin magnitude. This justifies the average treatment of the pseudofermion constraint in previous spin-1/2 PFFRG studies. We apply this method to the antiferromagnetic J1−J2 honeycomb Heisenberg model with nearest-neighbor J1>0 and second-neighbor J2>0 interactions. Mapping out the phase diagram in the J2/J1−S plane, we find that upon increasing S, quantum fluctuations are rapidly decreasing. In particular, already at S=1 we find no indication for a magnetically disordered phase. In the limit S→∞, the known phase diagram of the classical system is exactly reproduced. More generally, we prove that for S→∞ the PFFRG approach is identical to the Luttinger-Tisza method.

description: Helium nanodroplets doped with polar molecules are studied by electrostatic deflection. This broadly applicable method allows even polyatomic molecules to attain sub-Kelvin temperatures and nearly full orientation in the field. The resulting intense force from the field gradient strongly deflects even droplets with tens of thousands of atoms, the most massive neutral systems studied by beam "deflectometry." We use the deflections to extract droplet size distributions. Moreover, since each host droplet deflects according to its mass, spatial filtering of the deflected beam translates into size filtering of neutral fragile nanodroplets. As an example, we measure the dopant ionization probability as a function of droplet radius and determine the mean free path for charge hopping through the helium matrix. The technique will enable separation of doped and neat nanodroplets and size-dependent spectroscopic studies.

description: Online learning algorithms update models via one sample per iteration, thus efficient to process large-scale datasets and useful to detect malicious events for social benefits, such as disease outbreak and traffic congestion on the fly. However, existing algorithms for graph-structured models focused on the offline setting and the least square loss, incapable for online setting, while methods designed for online setting cannot be directly applied to the problem of complex (usually non-convex) graph-structured sparsity model. To address these limitations, in this paper we propose a new algorithm for graph-structured sparsity constraint problems under online setting, which we call \textsc{GraphDA}. The key part in \textsc{GraphDA} is to project both averaging gradient (in dual space) and primal variables (in primal space) onto lower dimensional subspaces, thus capturing the graph-structured sparsity effectively. Furthermore, the objective functions assumed here are generally convex so as to handle different losses for online learning settings. To the best of our knowledge, \textsc{GraphDA} is the first online learning algorithm for graph-structure constrained optimization problems. To validate our method, we conduct extensive experiments on both benchmark graph and real-world graph datasets. Our experiment results show that, compared to other baseline methods, \textsc{GraphDA} not only improves classification performance, but also successfully captures graph-structured features more effectively, hence stronger interpretability.

description: We use the synoptic maps of the photospheric magnetic field observed at Wilcox Solar Observatory, Mount Wilson Observatory, Kitt Peak, SOHO/MDI, SOLIS/VSM, and SDO/HMI to study the distribution of weak photospheric magnetic field values in 1974-2018. We fit the histogram distribution of weak field values for each synoptic map of the six data-sets separately with a parametrized Gaussian function in order to calculate the possible shift (to be called here the weak-field asymmetry) of the maximum of the Gaussian distribution from zero. We estimate the statistical significance of the weak-field asymmetry for each rotation. We also calculate several versions of lower-resolution synoptic maps from the high-resolution maps and calculate their rotational weak-field asymmetries. We find that the weak-field asymmetries increase with decreasing map resolution. A very large fraction of weak-field asymmetries are statistically significant, with the fraction of significant weak-field asymmetries increasing with decreasing resolution. Significant weak-field asymmetries of high- and low-resolution maps mainly occur at the same times and have the same sign. Weak-field asymmetries for the different data-sets and resolutions vary quite similarly in time, and their mutual correlations are very high, especially for low-resolution maps. These results give strong evidence for weak-field asymmetries reflecting a real feature of weak field values, which is best seen in medium- and low-resolution synoptic maps and is most likely related to the supergranulation scale of the photospheric field.

description: Family TRICHOGYPSIIDAE n. fam.   TYPE GENUS. — Trichogypsia Carter, 1871 by original designation.
DIAGNOSIS. — Baeriida with a skeleton entirely formed by diactine spicules.
DESCRIPTION
We propose to put sponges that have affinities with the Baeriidae, but that have only diactine spicules in the family Trichogypsiidae. As discussed above, one of the characteristics of the Baeriida is the presence of small “mortar-shaped” diactines that make up either all of, or a large part of a specific portion of the skeleton. The Trichogypsiidae have large diactines, which are probably not homologous with “mortar-shaped” diactines. It is difficult to establish whether the absence of triactine spicules is a primitive condition or is a consequence of a secondary reduction of the skeleton. In the Leucosoleniida, diactines are the first spicules to be secreted, but it is not known if this is also true for the Baeriida. All the Trichogypsiidae are very poorly known, having been described in early studies from a small number of specimens; there are no recent studies that provide a detailed description of their cytology or biology. Up to now, the Trichogypsiidae have been only described from boreal or arctic regions.

description: The Andreev-Thurston theorem states that for any triangulation of a closed orientable surface Σ_g of genus g which is covered by a simple graph in the universal cover, there exists a unique metric of curvature 1, 0 or -1 on the surface depending on whether g=0, 1 or \ge 2 such that the surface with this metric admits a circle packing with combinatorics given by the triangulation. Furthermore, the circle packing is essentially rigid, that is, unique up to conformal automorphisms of the surface isotopic to the identity. In this paper, we consider projective structures on the surface Σ_g where circle packings are also defined. We show that the space of projective structures on a surface of genus g \ge 2 which admits a circle packing by one circle is homeomorphic to R^{6g-6} and furthermore that the circle packing is rigid on such surfaces.

Ωστόσο, η αγάπη για το διάβασμα και το βιβλίο μπορεί να έρθει πιο σύντομα σε εκείνα τα παιδιά, τα οποία έχουν αποκτήσει το αναγνωστικό κίνητρο. Τα παιδιά συνηθίζουν να στρέφονται προς τα βιβλία που εξάπτουν την περιέργειά τους και επιθυμούν να ανακαλύψουν τον φανταστικό κόσμο τους. Ένα είδος βιβλίου το οποίο περιέχει τα χαρακτηριστικά αυτά, της εξερεύνησης και της φαντασίας, αποτελεί το παραμύθι. Είναι το πρώτο και το πιο ευχάριστο βιβλίο των μικρών παιδιών, αφού αποτελεί το αφήγημα το οποίο φέρει στοιχεία παιδικού παιχνιδιού. Όμως, δεν αρκεί μια τυπική ανάγνωση του παραμυθιού προκειμένου τα παιδιά να αποκτήσουν το ενδιαφέρον για να το διαβάσουν. Το ζητούμενο είναι τα παιδιά να γνωρίσουν τη δυναμική των παραμυθιών. Τα παραμύθια δεν είναι βιβλία μόνο για ανάγνωση, αλλά και για έμπνευση και δημιουργικότητα. Μέσα από τη δημιουργική αξιοποίησή τους τα παιδιά ανακαλύπτουν διάφορες πτυχές της ιστορίας τους και αρχίζουν να αποκτούν μια σχέση οικειότητας μαζί τους. Σε αυτό το πλαίσιο διαμορφώθηκε το πρώτο μέρος της παρούσας εργασίας στηριζόμενο στη βιβλιογραφική μελέτη του φαινομένου, ενώ το δεύτερο μέρος το οποίο αφορά στο πεδίο της έρευνας προσέγγισε το ίδιο φαινόμενο σε πρακτικό επίπεδο μέσα από τον σχεδιασμό και την υλοποίηση παρεμβάσεων. Συγκεκριμένα, για τις ανάγκες της παρούσας έρευνας επιλέχθηκε να πραγματοποιηθούν ορισμένες δραστηριότητες δημιουργικής γραφής οι οποίες έχουν διαμορφωθεί στη βάση τριών παραμυθιών. Σκοπός της επιλογής αυτής και της έρευνας, εν γένει, ήταν να διερευνηθεί αν οι συγκεκριμένες δραστηριότητες δημιουργικής γραφής οι οποίες απαιτούν για την εκπόνησή τους την ενασχόληση και την αξιοποίηση στοιχείων από τα παραμύθια, μπορούν, τελικά, να αποτελέσουν ένα κίνητρο για τα παιδιά που φοιτούν στην τρίτη τάξη του δημοτικού, ώστε τα ίδια να αποκτήσουν αναγνωστικό ενδιαφέρον για τα παραμύθια που έχουν επιλεγεί.

DESCRIPTION
 Haeckel (1872) described two subspecies that were subsequently raised by Dendy & Row (1913) to the species level: Trichogypsia (Leucyssa) incrustans Haeckel, 1872 and T. villosa Carter, 1871. He pointed out the similarity of both the external form and the organization of the aquiferous system to Baeria nivea, but we have no information on the internal organization of the choanoderm or the choanoskeleton. We have examined the slide prepared from the original specimen, described by Carter (1871) (BMNH 1870.10.1.9). It contains a fragment of an encrusting sponge with a thick cortex elevated in conules. The cortex is supported by very densely packed parallel diactines, arranged in bunches in the conules. A large, deep cavity present at the surface is surrounded by a particular skeleton composed of bent diactines. A canal parallel to the surface is connected to this cavity. Both the canal surface and the internal skeleton consist of straight or slightly curved spiny diactines that form a rather loose network (Fig. 46).

description: We report the BeppoSAX detection of a hard X-ray excess in the X-ray spectrum of the classical high-ionization Seyfert 2 galaxy Tol0109-383. The X-ray emission of this source observed below 7 keV is dominated by reflection from both cold and ionized gas, as seen in the ASCA data. The excess hard X-ray emission is presumably due to the central source absorbed by an optically thick obscuring torus with N(H)~2e24 cm-2. The strong cold X-ray reflection, if it is produced at the inner surface of the torus, is consistent with the picture where much of the inner nucleus of Tol0109-383 is exposed to direct view, as indicated by optical and infrared properties. However, the X-ray absorption must occur at small radii in order to hide the central X-ray source but leave the optical high-ionization emission line region unobscured. This may also be the case for objects like the Seyfert 1 galaxy Mrk231.

DESCRIPTION
 Dendy & Row (1913) proposed the genus Kuarraphis for a sponge described by Haeckel (1872) that is characterized by the presence of only needle-eye spicules. The sponge is encrusting, has a leuconoid organization without an atrium, and has irregular exhalant canals. Haeckel (1872) pointed out the similarity of the choanosome and the skeleton of this sponge with those described by him in the “subgenus Leucomalthe ”, which comprises the species that we place now in the Baeriidae. As indicated by Dendy & Row (1913), the “needle-eye” spicules are similar to diapasons, and are also found in Baeria ochotensis.

description: The recently discovered thermally induced magnetization switching (TIMS) induced by single femtosecond laser pulses in ferrimagnetic GdFeCo alloys proceeds on the picosecond time-scale. The rate at which data can be changed for use of TIMS in technological devices is limited by the processes leading to thermal equilibrium. In the present work, we address the question of whether it is possible to further excite switching via TIMS well before thermal equilibrium between subsystems is reached. In particular, we investigate the conditions for double thermally induced magnetic switching by the application of two shortly delayed laser pulses. These conditions become relevant for potential applications as it sets both a limit to rewrite data and demonstrates the importance of spatial confinement of a heat pulse to bit size, as neighboring bits may be accidentally re-switched for spatially extended pulse spots. To demonstrate this effect, we theoretically study the switching behavior in a prototypical ferrimagnetic GdFeCo alloy as a function of composition. We use computer simulations based on thermal atomistic spin dynamics and demonstrate the possibility of inducing a second switching event well before thermal equilibrium is reached and define the conditions under which it can occur. Our theoretical findings could serve as a guidance for further understanding of TIMS as well as to act as a guide for future applications.
Steady states of a driven dissipative dipolar XXZ chain

description: We study theoretically a driven dissipative one-dimensional XXZ spin$-1/2$ chain with dipole coupling and a tunable strength of the Ising and XY interaction. Within a mean-field approximation, we find a rich phase diagram with uniform, spin density wave, antiferromagnetic and oscillatory phases, as well as regions of phase bistability. We study the phase diagram of small quantum systems using exact diagonalisation, and compare the results to the mean-field theory. We find that while expectation values only capture the uniform phases of the mean-field theory, fluctuations about these expectation values give signatures of spatially non-uniform phases and bistabilities. We find these signatures for all ratios of the Ising to XY interaction, showing that they appear to be general features of spin$-1/2$ systems

 TYPE SPECIES. — Leucyssa spongilla Haeckel, 1872 by monotypy.
DIAGNOSIS. — Trichogypsiidae (?) with a skeleton composed only of smooth diactines.
DESCRIPTION
 The external shape of this sponge, which has a pedunculate cormus with a large clathrate body of anastomosed tubes, is quite different from both the Baeriida and Leucosoleniida, and is rather common among the Clathrinida. However, Eilhardia also has quite an unusual shape, and it is possible that our knowledge of only a very small number of sponges in the Baeriida gives the impression of a great divergence of the observed forms. We place this sponge among the Baeriida, following Haeckel’s (1872) description of the rather irregular alveolar choanosome supported by a dense skeleton of small diactines, scattered without order.

Evidence for pressure induced polarization rotation, octahedral tilting and reentrant ferroelectric phase in tetragonal (Pb0.5Bi0.5)(Ti0.5Fe0.5)O3

description: Despite the technological significance of the tetragonal PbTiO3 for the piezoelectric transducer industry, its high pressure behaviour is quite controversial as two entirely different scenarios, involving pressure induced (1) morphotropic phase boundary (MPB) like structural transition with concomitant rotation of the ferroelectric polarization vector and (2) antiferrodistortive (AFD) phase transition followed by emergence of a reentrant ferroelectric phase, have been proposed in recent theoretical and experimental studies. We have attempted to address these controversies through a high resolution synchrotron x-ray diffraction study of pressure induced phase transitions in the tetragonal phase of a modified PbTiO3 composition containing 50% BiFeO3, where BiFeO3 was added to enhance the AFD instability of PbTiO3. We present here the first experimental evidence for the presence of the characteristic superlattice reflections due to an AFD transition at a moderate pressure pc1 ~2.15 GPa in broad agreement with scenario (2), but the high pressure ferroelectric phase belongs to the monoclinic space group Cc, and not the tetragonal space group I4cm predicted under scenario (2), which permits the rotation of the ferroelectric polarization vector as per scenario (1). We show that the monoclinic distortion angle and ferroelectric polarization of the Cc phase initially decrease with increasing pressure for p < 7 GPa, but start increasing above pc2 ~ 7 GPa due to an isostructural Cc-I to Cc-II transition reminiscent of MA(apc > bpc ~ cpc) to MB(apc< bpc ~ cpc) transition predicted for MPB systems. We also show that octahedral tilting provides an efficient mechanism for accommodating pressure induced volume reduction for the stabilisation of the reentrant ferroelectric phase Cc-II.

description: We present new optical spectroscopy of the high-redshift powerful radio galaxy MRC 0406$-$244 at redshift of 2.429. We find that the two extensions toward NW and SE probed in the rest-frame ultraviolet image are heated mainly by the nonthermal continuum of the active galactic nucleus. However, each extension shows a shell-like morphology, suggesting that they are a pair of superbubbles induced by the superwind activity rather than by the interaction between the radio jet and the ambient gas clouds. If this is the case, the intense starburst responsible for the formation of superbubbles could occur $\sim 1 \times 10^9$ yr ago. On the other hand, the age of the radio jets may be of the order of $\sim 10^6$ yr, being much shorter than the starburst age. Therefore, the two events, i.e., the starburst and the radio-jet activities, are independent phenomena. However, their directions of the expanding motions could be governed by the rotational motion of the gaseous component in the host galaxy. This idea appears to explain the alignment effect of MRC 0406$-$244.
