description: Intelligent Reflecting Surface (IRS) has been recently proposed as a promising solution to enhance the spectral and energy efficiency of future wireless networks by tuning a massive number of low-cost passive reflecting elements and thereby constructing favorable wireless propagation environment. Different from the prior works that focus on link-level performance optimization for IRS-aided wireless systems, this letter characterizes the spatial throughput of a single-cell multiuser system aided by multiple IRSs that are randomly deployed in the cell. It is shown by simulation that our analysis is valid and the IRS-aided system outperforms the full-duplex relay-aided counterpart system in terms of spatial throughput when the number of IRSs exceeds a certain value. Moreover, it is shown that different deploying strategies for IRSs/active relays should be adopted for their respective throughput maximization. Finally, it is revealed that given the total number of reflecting elements for IRSs, the system spatial throughput increases when fewer IRSs are deployed each with more reflecting elements, but at the cost of more spatially varying user rates.

description: Genus Euchonicoloides gen. nov.
Diagnosis. Adult female body highly transformed, comprising ectosoma connected via short stalk to flattened endosoma located within host. Ectosoma comprising fused cephalothorax and trunk incorporating abdomen. Endosoma discoid to lobate, with well defined margins. Ectosoma elongate to squat, with or without traces of trunk segmentation. Genital apertures paired, located at posterolateral angles of trunk, either side of vestigial abdomen. Abdomen incorporated into trunk, lacking caudal rami and anal slit. Cement glands paired, conspicuous in posterior part of trunk in mature females. Egg sacs uniseriate or biseriate. Ectosoma with pair of antennae close to base of stalk. Antennae 2-segmented, subchelate, comprising robust basal segment and curved subchela. Antennules, other mouthparts and swimming legs all lacking. Male unknown.
Type species: Euchonicoloides elongatus gen. et sp. nov., by original designation.
Etymology. The name of the new genus alludes to its close resemblance to Euchonicola gen. nov.
Remarks. The organization of the body of the new genus is similar to that of Euchonicola gen. nov. The type species of both genera share a subchelate antenna that terminates in a curved claw, and both lack maxillae which are present in the saccopsine genera. The new genus differs from Euchonicola gen. nov. in the incorporation of the abdomen into the trunk, in the lack of caudal rami and an anal slit on the vestigial abdomen, and in the absence of any vestiges of antennules.

description: We present first results of our NAOS-CONICA search for close substellar companions around young nearby stars. This program was started only a few months ago. We have obtained 1st epoch images of several targets which are unpublished young stars (age<100 Myrs), hence ideal targets to look for planetary companions. For one target star we could even take a 2nd epoch image. By comparing both images we could look for co-moving companions of the target star. Those data show clearly that the detection of planetary companions m <13 Mjup inward a saturn-like orbit (r<10 AU) is feasible with NAOS-CONICA and in addition that the astrometric confirmation of those companions is doable with only a few weeks of epoch difference.

description: We consider estimating the marginal likelihood in settings with independent and identically distributed (i.i.d.) data. We propose estimating the predictive distributions in a sequential factorization of the marginal likelihood in such settings by using stochastic gradient Markov Chain Monte Carlo techniques. This approach is far more efficient than traditional marginal likelihood estimation techniques such as nested sampling and annealed importance sampling due to its use of mini-batches to approximate the likelihood. Stability of the estimates is provided by an adaptive annealing schedule. The resulting stochastic gradient annealed importance sampling (SGAIS) technique, which is the key contribution of our paper, enables us to estimate the marginal likelihood of a number of models considerably faster than traditional approaches, with no noticeable loss of accuracy. An important benefit of our approach is that the marginal likelihood is calculated in an online fashion as data becomes available, allowing the estimates to be used for applications such as online weighted model combination.

description: The thermodynamics of the O(N) nonlinear sigma model in 1+1 dimensions is studied. We calculate the finite temperature effective potential in leading order in the 1/N expansion and show that at this order the effective potential can be made finite by temperature independent renormalization. We will show that this is not longer possible at next-to-leading order in 1/N. In that case one can only renormalize the minimum of the effective potential in a temperature independent way, which gives us finite physical quantities like the pressure.

description: We report on the production of a novel cold mixture of fermionic $^{53}$Cr and $^{6}$Li atoms delivered by two Zeeman-slowed atomic beams and collected within a magneto-optical trap (MOT). For lithium, we obtain clouds of up to $4 \,10^8$ atoms at temperatures of about $500\,μ$K. A gray optical molasses stage allows us to decrease the gas temperature down to $45(5)\,μ$K. For chromium, we obtain MOTs comprising up to $1.5\, 10^6$ atoms. The availability of magnetically trappable metastable $D$-states, from which $P$-state atoms can radiatively decay onto, enables to accumulate into the MOT quadrupole samples of up to $10^7$ $^{53}$Cr atoms. After repumping $D$-state atoms back into the cooling cycle, a final cooling stage decreases the chromium temperature down to $145(5)\,μ$K. While the presence of a lithium MOT decreases the lifetime of magnetically trapped $^{53}$Cr atoms, we obtain, within a 5 seconds duty cycle, samples of about $4\, 10^6$ chromium and $1.5\,10^8$ lithium atoms. Our work provides a crucial step towards the production of degenerate Cr-Li Fermi mixtures.

description: We propose to use precise estimators of mutual information (MI) to find least dependent components in a linearly mixed signal. On the one hand this seems to lead to better blind source separation than with any other presently available algorithm. On the other hand it has the advantage, compared to other implementations of `independent' component analysis (ICA) some of which are based on crude approximations for MI, that the numerical values of the MI can be used for: (i) estimating residual dependencies between the output components; (ii) estimating the reliability of the output, by comparing the pairwise MIs with those of re-mixed components; (iii) clustering the output according to the residual interdependencies. For the MI estimator we use a recently proposed k-nearest neighbor based algorithm. For time sequences we combine this with delay embedding, in order to take into account non-trivial time correlations. After several tests with artificial data, we apply the resulting MILCA (Mutual Information based Least dependent Component Analysis) algorithm to a real-world dataset, the ECG of a pregnant woman. The software implementation of the MILCA algorithm is freely available at http://www.fz-juelich.de/nic/cs/software

title: Dynamics of Climate and Tectonics on Surface Processes and Their Sedimentary Archives in the Colorado Plateau and Basin and Range, USA and the Calabrian Forearc, Sicily
Creators: name: Tanski, Natalie M.
Publisher: name: Utah State University

description: Landscapes change over time in response to movements of the Earth’s crust and the effects of climate. This dissertation examines how these factors shape different landscapes, focusing on erosion of river canyons in elevated plateaus, how the transport history in quartz sand may be encoded in its properties, and how a paleo-delta has formed in response to sea-level change and fault displacement. I use dating techniques, field methods, and topographic analyses to offer insight into erosional patterns and rates in different landscapes.
Rivers can take a long time to adjust to changes in boundary conditions, even after those changes have ceased. I studied the Colorado River incision history in the tectonically stable central Colorado Plateau of Utah, to understand the timing, spatial variability, and controls on canyon carving. The incision history and topography of the region show remarkable variability in erosion across the region and through time, with significant rapid incision of ~250 meters in the last 350,000 years. Results suggest this rapid erosion is a signal derived from baselevel fall by the Colorado River in the Grand Canyon region 5 million years ago. This study shows that even without major tectonic or climate change, landscapes can still maintain complex erosion patterns.
Optically stimulated luminescence sensitivity is a new technique used to study Earth’s surface processes. However, the geologic processes that induce a luminescence phenomenon in quartz are still unknown. I investigate the geologic controls on the luminescence sensitivity of quartz sand using rocks and modern and paleo- river sediments in a small mountainous catchment in northern Utah, USA. The results indicate that the luminescence phenomena in quartz is enhanced with the time spent at the Earth’s surface as the sand grain weathers, erodes, and is transported along hillslopes to river systems.
The Pagliara fan-delta in northeastern Sicily provides a unique opportunity to study how coastal sediments stack through time in response to climate and sea-level change and tectonic history. Dating of the delta using luminescence techniques, reveals that the delta formed 300 – 220 thousand years ago when accommodation space was generated by sea-level fall and subsidence from fault movement. After this time, river and shore processes began to excavate the delta, indicating a shift from sediment accumulation in the delta to tectonic uplift. Despite the change in tectonic stress revealed in the delta stratigraphy, the uplift and erosion rates of the region have remained relatively constant over the past 300,000 years.

description: In (1+2)-dimensional Poincaré gauge gravity, we start from a Lagrangian depending on torsion and curvature which includes additionally {\em translational} and {\em Lorentzian} Chern-Simons terms. Limiting ourselves to to a specific subcase, the Mielke-Baekler (MB) model, we derive the corresponding field equations (of Einstein-Cartan-Chern-Simons type) and find the general vacuum solution. We determine the properties of this solution, in particular its mass and its angular momentum. For vanishing torsion, we recover the BTZ-solution. We also derive the general conformally flat vacuum solution with torsion. In this framework, we discuss {\em Cartan's} (3-dimensional) {\em spiral staircase} and find that it is not only a special case of our new vacuum solution, but can alternatively be understood as a solution of the 3-dimensional Einstein-Cartan theory with matter of constant pressure and constant torque.

description: [Abridged] The chemical composition of two stars in WLM has been determined from high quality UVES data obtained at the VLT UT2 (program 65.N-0375). The model atmospheres analysis shows that they have the same metallicity, [Fe/H] = -0.38 +/-0.20, and [Mg/Fe] = -0.24 +/-0.16. This result suggests that the [alpha(Mg)/Fe] ratio in WLM may be suppressed relative to solar abundances (also supported by differential abundances relative to similar stars in NGC6822 and the SMC). The absolute Mg abundance, [Mg/H] = -0.62 is high relative to what is expected from the nebulae though, where two independent spectroscopic analyses of the HII regions in WLM yield [O/H] = -0.89. Intriguingly, the oxygen abundance determined from the OI 6158 feature in one WLM star is [O/H] = -0.21 +/-0.10, corresponding to five times higher than the nebular oxygen abundance. This is the first time that a significant difference between young stellar and nebular oxygen abundances has been found, and presently, there is no simple explanation for this difference. If the stellar abundances reflect the true composition of WLM, then this galaxy lies well above the metallicity-luminosity relationship for dwarf irregular galaxies. It also suggests that WLM is more chemically evolved than currently interpreted from its color-magnitude diagram.

description: The observation of helical surface states in Bi-based three-dimensional topological insulators has been a challenge since their theoretical prediction. The main issue raises when the Fermi level shifts deep into the bulk conduction band due to the unintentional doping. This results in a metallic conduction of the bulk which dominates the transport measurements and hinders the probing of the surface states in these experiments. In this study, we investigate various strategies to reduce the residual doping in Bi-based topological insulators. Flakes of Bi$_2$Se$_3$ and Bi$_{1.5}$Sb$_{0.5}$Te$_{1.7}$Se$_{1.3}$ are grown by physical vapor deposition and their structural and electronic properties are compared to mechanically exfoliated flakes. Using Raman spectroscopy, we explore the role of the substrate in this process and present the optimal conditions for the fabrication of high quality crystals. Despite of this improvement, we show that the vapor phase deposited flakes still suffer from structural disorder which leads to the residual n-type doping of the bulk. Using magneto-measurements we show that exfoliated flakes have better electrical properties and are thus more promising for the probing of surface states.

Type Material: Holotype ovigerous ♀ from Euchone sp., Mareano 2010110, Stn 556 (70° 38.38’N, 19° 23.8’E), depth 281 m, 0 4 August 2010; collected by A. Sikorski; NHMUK Reg. No. 2015.524. Paratype ovigerous ♀ from Euchone sp., Mareano 2010110, Stn 613 (70° 46.23’N, 20° 49.88’E), depth 246 m, 19 September 2010; collected by A. Sikorski; NHMUK Reg. No. 2015.444. Paratype ovigerous ♀ from Euchone sp., Snorre B 0 2, Stn 7-1 (61.52516°N, 02.247374°E), depth 355 m, 29 May 2002; collected by S. Gagaev; NHMUK Reg. No. 2015.443.
Differential diagnosis. Female body comprising elongate ectosoma connected via short, broad stalk to small discoid endosoma embedded within host (Fig. 25A). Ectosoma unsegmented, more or less cylindrical, about 6.2 to 6.3 times longer than wide: length of ectosoma 458 to 528 µm (based on 3 specimens); maximum width 76 to 84 µm. Paired cement glands slender, about 165 µm in length, extending through posterior third of trunk only. Stalk broad, located anteriorly on ectosoma (Fig. 25A, B). Endosoma discoid, narrower than width of trunk; with well defined edges (Fig. 25D). Antennules absent. Antennae positioned posterolateral to base of stalk; comprising robust basal segment and curved apical claw (Fig. 25B, D). Cement glands paired, extending anteriorly to reach about to middle of ectosoma. Genital apertures paired, located posterolaterally on trunk. Abdomen reduced to rounded lobe fully fused with trunk and located dorsally in middle of posterior margin (Fig. 25C); no anal slit present and caudal rami lacking. Egg sacs uniseriate, with up to 10 spherical eggs (Fig. 25B).
Etymology. The name of the new species refers to its elongate ectosoma, which is more than six times longer than wide.
Remarks. All three of the available specimens carried a single egg sac and the only intact egg sac contained 10 eggs. The eggs were arranged in a single series but the eggs are more or less spherical, not discoid as in caligiform copepods. This parasite is embedded in the head of its host so its egg sacs extend out with the tentacles of the host. Its elongate, cigar-shaped ectosoma which incorporates the abdomen, serves to distinguish this species from its congener described below.
This species is known only from females found on unidentified specimens of the sabellid genus Euchone collected at depths between 246 and 355 m off the coast of western and northern Norway.

description: Subjected to compressive stresses, soft polymers with stiffness gradients can display various buckling patterns. These compressive stresses can have different origins, like mechanical forces, temperature changes, or, for hydrogel materials, osmotic swelling. Here, we focus on the influence of the transient nature of osmotic swelling on the initiation of buckling in confined layered hydrogel structures. A constitutive model for transient hydrogel swelling is outlined and implemented as a user-subroutine for the commercial finite element software Abaqus. The finite element procedure is benchmarked against linear perturbation analysis results for equilibrium swelling showing excellent correspondence. Based on the finite element results we conclude that the initiation of buckling in a two-layered hydrogel structure is highly affected by transient swelling effects, with instability emerging at lower swelling ratios and later in time with a lower diffusion coefficient. In addition, for hard-on-soft systems the wavelength of the buckling pattern is found to decrease as the diffusivity of the material is reduced for gels with a relatively low stiffness gradient between the substrate and the upper film. This study highlights the difference between equilibrium and transient swelling when it comes to the onset of instability in hydrogels, which is believed to be of importance as a fundamental aspect of swelling as well as providing input to guiding principles in the design of specific hydrogel systems.

description: Much of the published work regarding the Isotropic Singularity is performed under the assumption that the matter source for the cosmological model is a barotropic perfect fluid, or even a perfect fluid with a $γ$-law equation of state. There are, however, some general properties of cosmological models which admit an Isotropic Singularity, irrespective of the matter source. In particular, we show that the Isotropic Singularity is a point-like singularity and that vacuum space-times cannot admit an Isotropic Singularity. The relationships between the Isotropic Singularity, and the energy conditions, and the Hubble parameter is explored. A review of work by the authors, regarding the Isotropic Singularity, is presented.

 Imprisoned in 1971, Mr. Rajavi was among the last group of political prisoners released thanks to the efforts of the Iranian people four days after Iran's departure from the shah in 1979.
 We could read in particular on posters and banners: “The world must know that Massoud is our leader”, “Khamenei, your end has arrived”, “The cogs of the reversal will turn at a faster speed”, “Let’s celebrate the 20th January, anniversary of the liberation of Massoud, the hope of the people and of the nation ”,“ The flames of the uprising will not be extinguished ”,“ Let us celebrate January 20 which marks the release of Massoud Rajavi from the prisons of shah ”and "By massacring the youth, Khamenei digs his own grave." Also, on the morning of January 3, 2020, resistance units posted portraits and messages of Maryam Rajavi, president-elect of the National Council of Resistance of Iran (NCRI), and Massoud Rajavi, leader of the Iranian Resistance in Tehran (on the highways of Niavaran and Al-e -Ahmad, and the districts of Monirieh, Sadeghieh and Vahidieh) as well as in the provinces, notably in Tabriz, Gorgan, Hamedan and Kachan.
 You could read on these posters: "The overthrow of the inhuman enemy is certain", "The resistance units guide the insurgent generation", "Be certain of the victory of our people", "Rise to overthrow the religious dictatorship "," The insurgent youth made the life of the mullahs a hell "," Blood shed by the youth of the country, hatch the tulips "," The martyrs of the uprising are the most alive of the living "," The Iranian people and his Resistance have sworn to overthrow this regime ”.

description: We study the Pauli equation on non-commutative plane. It is shown that the Supersymmetry algebra holds to all orders in the non-commutative parameter $θ$ in case the gyro-magnetic ratio $g$ is 2. Using Seiberg-Witten map, the first order in $θ$ correction to the spectrum is obtained in the case of uniform magnetic field. We find that the eigenstates in the non-commutative case are identical to the commutative case provided the magnetic field $B$ is everywhere replaced by $B(1+Bθ)$.

Fig. 118–121
 The H. hamifera species clade was established by Mey (2003). The species in the clade are characterized by having reduced apical membranous endothecal lobes, being replaced by the sclerotized part of the phallotheca. The phallotheca is deeply cleft apically, and together with the sclerotized phallotremal tongue in the middle, the apex of the phallic apparatus becomes trifid. The membranous subapical appendages originate basally, behind the phallotrema and constitute a pair of endothecal appendages. The tip of the phallic apparatus is entirely sclerotized and trifid. The phallotremal tongue is scarcely broader than the lateral lobes.
 Due to the high number of species in this clade we have found it practical to divide it further into species clusters based on morphological characteristics in the genitalia. The species clusters are not characterized by synapomorphies, but rather by morphological similarities, and constitute therefore not necessarily monophyletic groups. The sclerotized trifid apex of the phallic apparatus, segment IX with its long apical lobe and pos teriorly shifted dorsum, and the elongating segment X with long digitiform and ventrad curving apicoventral setose lobes, are all rather conservative and uniform characters within this clade. In establishing clusters of the 41 species of the H. hamifera species clade we found that the formation of the intersegmental connection between segments IX and X constitute a complex of characters: (1) the high or low position of the granulous surface of the median keel on dorsum IX in relation to dorsum X; (2) the angle of the stepwise intersegmental depression between segments IX and X; (3) the step depth; (4) the basal position of the apicodorsal setose lobes; and (5) the size of the apicodorsal setose process.

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/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Star formation and gas flow history of a dwarf irregular galaxy traced by gas-phase and stellar metallicities

description: Studying the evolution of dwarf galaxies can provide insights into the characteristics of systems that can act as building blocks of massive galaxies. This paper discusses the history of star formation and gas flows (inflow and outflow) of a dwarf irregular galaxy in the Local Group, NGC 6822, from the viewpoint of gas-phase and stellar chemical abundance. Gas-phase oxygen abundance, stellar metallicity distribution and gas fraction data are compared to chemical evolution models in which continuous star formation and gas flows are assumed. If the galaxy is assumed to be a closed or an accretion-dominated system where steeper stellar initial mass functions are allowed, the observed gas-phase oxygen abundance and gas fraction can be explained simultaneously; however metallicity distributions predicted by the models seem to be inconsistent with the observed distribution, which suggests that the star formation, gas flows and/or chemical enrichment are more complex than assumed by the models. When NGC 6822 is assumed to be a system dominated by outflow, the observed values of gas-phase oxygen abundance and gas fraction can be explained, and the metallicity distributions predicted by some of the models are also roughly consistent with the observed distribution in the metallicity range of -2.0

description: Here, we report the successful synthesis of electron- (Ni) and hole- (K) doped bulk BaFe2As2 compounds by means of mechanical alloying (MA) process. The MA technique allows one to obtain amorphous phase BaFe2As2 with a homogeneous distribution of doping atoms at room temperature without continuous heating. We found the optimum time for high-energy milling is in the range between 1-1.5 hours. Using pre-synthesised FeAs and NiAs precursors, we successfully obtained BaFe2-xNixAs2 and Ba1-xKxFe2As2 superconducting bulk samples after short-range heat treatment. This method can be easily scaled according to industrial needs to provide high-quality bulk superconducting material for wires, trapped field magnets and other applications.

Dynamics of Q-Balls in an expanding universe

description: We analyse the evolution of light Q-balls in a cosmological background, and find a number of interesting features. For Q-balls formed with a size comparable to the Hubble radius, we demonstrate that there is no charge radiation, and that the Q-ball maintains a constant physical radius. Large expansion rates cause charge migration to the surface of the Q-ball, corresponding to a non-homogeneous internal rotation frequency. We argue that this is an important phenomenon as it leads to a large surface charge and possible fragmentation of the Q-ball. We also explore the deviation of the Q-ball profile function from the static case. By introducing a parameter $ε$, which is the ratio of the Hubble parameter to the frequency of oscillation of the Q-ball field, and using solutions to an analytically approximated equation for the profile function, we determine the dependence of the new features on the expansion rate. This allows us to gain an understanding of when they should be considered and when they can be neglected, thereby placing restrictions on the existence of homogeneous Q-balls in expanding backgrounds.

description: El nombre del Boom1 apareció ligado a un fenómeno de indiscutible éxito editorial surgido durante los años sesenta (Cfr. Donoso, 1972: 15); el problema fue su posterior definición en términos de generación o escuela, ya que las coordenadas cronológicas basadas en las fechas de nacimiento o publicación de la primera obra resultaban insuficientes; ni se trató tampoco de un movimiento generacional o de una estética específica (Cfr. Oviedo, 2001: 300). Como ejemplo ilustrativo podríamos citar
el de Lezama Lima, que, aunque nacido en 1912, no publica su primera novela, Paradiso, hasta 1966. En cambio, Vargas Llosa, nacido veinticuatro años más tarde,
alcanza notoriedad con La ciudad y los perros en 1963 (Shaw, 2005: 99).

description: We show that the recently formulated causal and stable first-order hydrodynamics has the same dynamics as Israel-Stewart theory for boost-invariant, Bjorken expanding systems with a conformal equation of state and a regulating sector determined by a constant relaxation time. In this case, the general solution of the new first-order formulation can be determined analytically.

Constraining the Cosmic Star Formation Rate with the MeV Background

description: The Cosmic Gamma-ray Background (CGB) in the MeV regime has been measured with COMPTEL and SMM. The origin of the CGB in this energy regime is believed to be dominated by gamma-rays from Type Ia supernovae. We calculate the CGB spectrum within the framework of FRW cosmology as a function of the cosmic star formation rate, SFR(z). Several estimates of the SFR(z) have been reported since the pioneering work of Madau et al. Here we discuss observational constraints on SFR(z) derived from models of the CGB. In particular, we consider the SFR obtained from Gamma-Ray Burst observations, which increases dramatically with redshift beyond z ~ 1 in contrast to most estimates which saturate or show a mild increase with redshift. Gamma-ray bursts may be the most powerful tracers of star formation in the early universe and thus provide signposts of the initial epoch of element synthesis. The star formation rate implied by GRB statistics results in a gamma-ray background that matches the observations more closely than that inferred from other tracers of star formation. This may provide some support for the GRB/SFR-paradigm, which in turn promises a powerful diagnostic of star formation, and thus cosmic chemical evolution, from the era of Population III stars to the present.
Successive superconducting transitions and Anderson localization effect in Ta$_{2}$S$_{2}$C

description: A complex carbide Ta$_{2}$S$_{2}$C consists of van der Waals (vdw)-bonded layers with a stacking sequence $...$ C-Ta-S-vdw-S-Ta-C- $...$ along the c axis. The magnetic properties of this compound have been studied from DC and AC magnetic susceptibility. Ta$_{2}$S$_{2}$C undergoes successive superconducting transitions of a hierachical nature at $T_{cl} = 3.61 \pm 0.01$ K [$H_{c1}^{(l)}(0) = 28 \pm 2$ Oe and $H_{c2}^{(l)}(0) = 7.7 \pm 0.2$ kOe] and $T_{cu} = 9.0 \pm 0.2$ K [$H_{c2}^{(u)}(0) = 6.0 \pm 0.3$ kOe]. The intermediate phase between $T_{cu}$ and $T_{cl}$, where $δχ(= χ_{FC} - χ_{ZFC}) \approx 0$, is an intra-grain superconductive state occurring in the Ta-C layers in Ta$_{2}$S$_{2}$C. The low temperature phase below $T_{cl}$, where $δχ$ clearly appears, is an inter-grain superconductive state. The magnetic susceptibility at $H$ well above $H_{c2}^{(l)}(0)$ is described by a sum of a diamagnetic susceptibility and a Curie-like behavior. The latter is due to the localized magnetic moments of conduction electrons associated with the Anderson localization effect, occurring in the 1T-TaS$_{2}$ type structure in Ta$_{2}$S$_{2}$C.

Material examined: 4 ovigerous ♀♀ from Polycirrus norvegicus, Liverpool Bay, Unicomarine 18443 Stn M10, (53° 31’N, 03° 31’W), depth unknown, 0 5 September 1996. NHMUK Reg. Nos 2018.183-186. 2 ovigerous and 2 mature ♀♀ from Polycirrus sp., Liverpool Bay, CEFAS (Unico 29118 CEFLBY), (53.5217°N, 03.52147°W), depth unknown, September 2002.
Descriptions. Four ovigerous females from P. norvegicus were measured: mean ectosoma length was 2.29 mm (range 1.69 to 2.93 mm), mean maximum width of ectosoma (Fig. 27C) was 0.63 mm (range 0.50 to 0.75 mm); mean L:W ratio 3.66 (range 3.42:1 to 3.90:1). The egg sacs are multiseriate, slightly curved and up to 2.4 mm long for largest adult female (2.93 mm ectosoma length).
Remarks. The material from P. norvegicus is tentatively attributed to X. brumpti solely on the basis of the L:W ratio of the ectosoma: the mean ratio was 3.66:1. This is less than 4.0:1, the lower limit of the range given by Caullery & Mesnil (1915, 1919). The range exhibited by specimens here attributed to X. brumpti was 3.42 to 3.9:1 and it is effectively contiguous with the range of 1.75:1 up to 3.39:1 found here for X. alleni. Now that larger samples from a wider range of hosts have become available for study, we find that there is no clear gap between the two species in the L:W ratio. Our dividing line between X. alleni (L:W ratio less than 3.40:1) and X. brumpti (more than 3.40:1) is arbitrary. As commented for X. alleni above, morphology based identifications such as these should be regarded as in need of validation once molecular diagnostics become available.
