(Fig. 11 E, F)
 Material examined. Holotype: NIWA 61258, from cruise TAN0104, Stn 3, 42°45.48– 42°45.18’S, 179°59.47– 179°59.54’ W, “Graveyard” Seamount, Chatham Rise, 943–1097 m depth, collected 15 April 2001.
 Distribution. “Graveyard Seamount Complex”, north-central Chatham Rise, New Zealand, 943–1097 m.
 Etymology. Latin, superlative of minutus, small.
 Description. Colony exceedingly tiny, comprising just five autozooids and a central gonozooid, supported on a smooth, short pedestal. Typical cancelli lacking, but five small pores present, one basal to each zooidal aperture. Peristomes relatively thick-walled, with up to five short, blunt processes; all exterior surfaces of zooidal disc relatively coarsely granular. Brood chamber small, oval, its granular surface merging into that of the peristomes that surround it, the ooeciostome circular, smooth with a thin rim.
 Remarks. This species is so far known only from the type locality, which yielded a single fertile colony. It is unquestionably the smallest cyclostome species known ― in fact the smallest calcified bryozoan known ― and the entire colony could easily fit inside an individual zooid of most cheilostome species; its individual zooids are smaller than the mature zooids of the interstitial ctenostome bryozoan Monobryozoon ambulans (see Hayward 1985) which has minute colonies with only one autozooid.
 The generic attribution is uncertain. The zooids of D. minutissima closely resemble those of D. minicamera but the smooth basal pedestal is lacking in this species. The pedestal, which is exterior-walled, may be homologous with the conical peduncle of the Cretaceous–Miocene genus Lichenopora (Gordon & Taylor 1997). The ooeciostome of D. minutissima is round, quite unlike the broad transverse opening in D. minicamera.

description: Until now, there has been no integrated study of the cognitive, motor and academic developments in children in the Arab world. In this study we investigated gender differences in those three areas in primary school-aged children in Oman and as well as the inter-relations between those three aspects of development. Ninety-five third graders completed four working memory tests, a mental rotation test and a motor test. Furthermore, the marks in math, science and Arabic language were registered. The result showed that there were small gender differences: Girls performed better in one of the working memory tests and boys in the coordination motor test. The study also showed that there were significant correlations between cognitive variables and academic performance, as well as two significant correlations between motor performance and marks in math and science. Marks in math correlated with the performances in the 20 m run and the coordination test, whereas the marks in science correlated with the ball-leg-wall test, the coordination test, and the endurance test. Regression analysis showed that all marks were predicted by the working memory and mental rotation performance as well as the motor ability. This means that academic achievement in Oman could be predicted by basic cognitive as well as motor abilities.

DEMAND PROJECTIONS FOR POULTRY FEEDS: IMPLICATIONS FOR WHEAT AND MAIZE PRODUCTION IN BANGLADESH

description: Wheat and maize are important components of poultry feeds. The demand for wheat and maize, therefore, is expected to increase with the currently experienced sharp growth of poultry farms in Bangladesh. This analysis carries out projections of demand for poultry feeds and its implications for wheat and maize production in Bangladesh over the next 20 years. Under the scenario of rural consumption data from FMRSP and urban consumption data from HES source, and fixed income elasticity of demand, the Demand Analysis Approach projects the use of total grains (as poultry feeds) as 665, 746, 826 and 898 thousand metric tons, for the years 2005, 2010, 2015 and 2020 respectively. Under the scenario of trend growth rate of poultry population and commercial farms taken as equal to current population growth rate, the Trend Analysis Approach projects the total grains as 683, 740, 801 and 867 thousand metric tons, for these years respectively. The use of grain for poultry feeds for the base year 2000 is estimated to be 631 thousand metric tons. Of this, wheat accounts for 22 and maize accounts for 78 per cent. The requirement of wheat as poultry feed is only 8 per cent of the total domestic production while the requirement of maize as poultry feed is nearly 8 times its domestic production. Our field survey suggests that one of the major reasons of maize production gaining no popularity in Bangladesh relates to lack of incentives on the part of the cultivators. Some motivational steps and market interventions are, therefore, needed in this respect.

description: Three-point functions of Wess-Zumino-Witten models are investigated. In particular, we study the level-dependence of three-point functions in the models based on algebras $su(3)$ and $su(4)$. We find a correspondence with Berenstein-Zelevinsky triangles. Using previous work connecting those triangles to the fusion multiplicities, and the Gepner-Witten depth rule, we explain how to construct the full three-point functions. We show how their level-dependence is similar to that of the related fusion multiplicity. For example, the concept of threshold level plays a prominent role, as it does for fusion.

description: Westerbork Radio Synthesis Telescope observation of the galaxy VV29=Arp188=UGC10214 shows that there are at least three distinct dynamical components whose kinematics can be traced in 21cm line emission. The system appears to be the result of a galaxy-galaxy interaction. We identify a sufficient number of dynamical elements containing baryons (stars and neutral gas) that there is no compelling reason to postulate the presence of an additional dark matter halo that is devoid of detectable baryons. The central galaxy VV29a is massive (V_rot = 330 km/s) and gas rich (M_HI} = 6x10^9 Msolar). The distinctive optical plume (VV29b), which extends eastward from the main galaxy, is also gas rich (M_HI = 3x10^9 Msolar) and has a very low gradient in line of sight velocity (<30 km/s) over 70kpc. On the western side, there is an HI feature of M_HI = 4x10^8 Msolar that participates strongly in orbital motion about the host in the same sense of rotation as the VV29a itself. A blue, less massive, gas-rich galaxy "VV29c" (M_HI = 9x10^8 Msolar) appears clearly in the HI maps as an 170 km/s wide spectral feature, seen in projection against or, more likely, behind the west side of the host disk. Its high recessional velocity is counter to the host rotation direction. The optical images of Trentham et al (2001) show signs of this blue dwarf against the redder VV29a disk. The companion galaxy CGCG27-021=MGC09-26-54 (at projected distance 115 kpc) is not detected in 21cm line emission (M_HI<10^9Msolar).

description: Dust growth is often neglected when building models of protoplanetary disks due to its complexity and computational expense. However, it does play a major role in shaping the evolution of protoplanetary dust and planet formation. In this paper, we present a numerical model coupling 2-D hydrodynamic evolution of a protoplanetary disk, including a Jupiter-mass planet, and dust coagulation. This is obtained by including multiple dust fluids in a single grid-based hydrodynamic simulation and solving the Smoluchowski equation for dust coagulation on top of solving for the hydrodynamic evolution. We find that fragmentation of dust aggregates trapped in a pressure bump outside of the planetary gap leads to an enhancement in density of small grains. We compare the results obtained from the full coagulation treatment to the commonly used, fixed dust size approach and to previously applied, less computationally intensive methods for including dust coagulation. We find that the full coagulation results cannot be reproduced using the fixed-size treatment, but some can be mimicked using a relatively simple method for estimating the characteristic dust size in every grid cell.

The results are based on a study of the quasimomentum $k(z)$ corresponding to $H$. We consider $k(z)$ as a conformal mapping in the complex plane. We obtain the trace identities which connect integrals of the Lyapunov exponent over the gaps with the normalised traces of powers of $H$.

description: We have earlier shown that cosmic strings moving through the plasma at the time of a first order quark-hadron transition in the early universe can generate large scale baryon inhomogeneities. In this paper, we calculate detailed structure of these inhomogeneities at the quark-hadron transition. Our calculations show that the inhomogeneities generated by cosmic string wakes can strongly affect nucleosynthesis calculations. A comparison with observational data suggests that such baryon inhomogeneities should not have existed at the nucleosynthesis epoch. If this disagreement holds with more accurate observations, then it will lead to the conclusions that cosmic string formation scales above $10^{14} - 10^{15}$ GeV may not be consistent with nucleosynthesis and CMBR observations. Alternatively, some other input in our calculation should be constrained, for example, if the average string velocity remains sufficiently small so that significant density perturbations are never produced at the QCD scale, or if strings move ultra-relativistically so that string wakes are very thin, trapping negligible amount of baryons. Finally, if quark-hadron transition is not of first order then our calculations do not apply.

Saturated Free Algebras and Almost Indiscernible Theories

description: We extend the concept of "almost indiscernible theory" introduced by Pillay and Sklinos in [Bull. Symb. Log., 2015] (which was itself a modernization and expansion of Baldwin and Shelah [Algebra Universalis, 1983]), to uncountable languages and uncountable parameter sequences. Roughly speaking a theory $T$ is almost indiscernible if some saturated model is in the algebraic closure of an indiscernible set of sequences. We show that such a theory $T$ is nonmultidimensional, superstable, and stable in all cardinals $\ge |T |$ . We prove a structure theorem for sufficiently large $a$-models $M$: Theorem 2.10 which states that over a suitable base, $M$ is in the algebraic closure of an independent set of realizations of weight one types (in possibly infinitely many variables). We also explore further the saturated free algebras of Baldwin and Shelah in both the countable and uncountable context. We study in particular theories and varieties of $R$-modules, characterizing those rings $R$ for which the free $R$-module on $|R|^+$ generators is saturated (Theorem 3.15), and pointing out a counterexample to a conjecture from Pillay-Sklinos (Example 3.16).

description: During a 50 ks monitoring observation of the Galactic bulge performed in September 1999 by the Wide Field Cameras on board the BeppoSAX satellite, an X-ray burst was detected from a sky position ~3 degrees off the Galactic centre. No previously known X-ray sources are located within the position error circle of the observed burst. The new burster, SAX J1752.3-3138, did not show any persistent emission during the whole observation. No other bursting events, as well as steady emission, were reported so far by other instruments or detected in the WFC archive, which covers ~6 Ms and ~4 Ms for burst and persistent luminosity detection, respectively, starting from August 1996. Unless the source is a very weak transient, this could indicate SAX J1752.3-3138 is an atypical burster, a member of a possibly new class of sources characterised by very low steady luminosities and accretion rates (L_x < 10^35 erg/s) and extremely rare bursting activity. The characteristics of the detected burst are consistent with a type I event, identifying the source as a weakly magnetised neutron star in a low-mass X-ray binary system. Evidence for photospheric radius expansion due to Eddington-limited burst luminosity allows to estimate the distance to the source (~9 kpc).

description: We study global minimizers of a continuum Landau-De Gennes energy functional for nematic liquid crystals, in three-dimensional domains. Assuming smooth and uniaxial (e.g. homeotropic) boundary conditions and a corresponding physically relevant norm constraint (Lyuksyutov constraint) in the interior, we prove full regularity up to the boundary for the minimizers. As a consequence, in a relevant range (which we call the Lyuksyutov regime) of parameters of the model we show that even without the norm constraint isotropic melting is anyway avoided in the energy minimizing configurations. Finally, we describe a class of boundary data including radial anchoring which yield in both the previous situations as minimizers smooth configurations whose level sets of the biaxiality carry nontrivial topology. Results in this paper will be largely employed and refined in the next papers of our series. In particular, in [DMP2], we will prove that for smooth minimizers in a restricted class of axially symmetric configurations, the level sets of the biaxiality are generically finite union of tori of revolution.

Objective

To review the technical aspects of body composition assessment by dual-energy X-ray absorptiometry (DXA) and other methods based on the most recent scientific evidence.

Materials and methods

This Official Position is a result of efforts by the Scientific Committee of the Brazilian Association of Bone Assessment and Metabolism (Associação Brasileira de Avaliação Óssea e Osteometabolismo, ABRASSO) and health care professionals with expertise in body composition assessment who were invited to contribute to the preparation of this document. The authors searched current databases for relevant publications. In this first part of the Official Position, the authors discuss the different methods and parameters used for body composition assessment, general principles of DXA, and aspects of the acquisition and analysis of DXA scans.

Conclusion

Considering aspects of accuracy, precision, cost, duration, and ability to evaluate all three compartments, DXA is considered the gold-standard method for body composition assessment, particularly for the evaluation of fat mass. In order to ensure reliable, adequate, and reproducible DXA reports, great attention is required regarding quality control procedures, preparation, removal of external artifacts, imaging acquisition, and data analysis and interpretation.

description: We present a deep machine learning (ML)-based technique for accurately determining $σ_8$ and $Ω_m$ from mock 3D galaxy surveys. The mock surveys are built from the AbacusCosmos suite of $N$-body simulations, which comprises 40 cosmological volume simulations spanning a range of cosmological models, and we account for uncertainties in galaxy formation scenarios through the use of generalized halo occupation distributions (HODs). We explore a trio of ML models: a 3D convolutional neural network (CNN), a power-spectrum-based fully connected network, and a hybrid approach that merges the two to combine physically motivated summary statistics with flexible CNNs. We describe best practices for training a deep model on a suite of matched-phase simulations and we test our model on a completely independent sample that uses previously unseen initial conditions, cosmological parameters, and HOD parameters. Despite the fact that the mock observations are quite small ($\sim0.07h^{-3}\,\mathrm{Gpc}^3$) and the training data span a large parameter space (6 cosmological and 6 HOD parameters), the CNN and hybrid CNN can constrain $σ_8$ and $Ω_m$ to $\sim3\%$ and $\sim4\%$, respectively.

description: Environmental agencies and utilities wishing to support environmental projects face the challenge of deciding which of the many possible projects they should support with their limited resources. Projects vary greatly in their benefits and costs, so selecting the best projects can make a major difference to the level of benefits that can be generated for a given budget. Key principles for ranking projects are presented and explained. Suitable formulas to use as a metrics for ranking projects are developed and explained. The formulas account for valuation of benefits, the effectiveness of management, time lags, behaviour change, various risks and various costs. The formulas are designed to strike a balance between theoretical rigour and reasonable simplifications. A number of common mistakes to avoid are outlined. Sample templates for project proposals and spreadsheets for ranking projects are provided, to make it easy to put the principles into practice.

description: We study a system of spinless electrons moving in a two dimensional noncommutative space subject to a perpendicular magnetic field $\vec B$ and confined by a harmonic potential type ${1\over 2}mw_{0}r^2$. We look for the orbital magnetism of the electrons in different regimes of temperature $T$, magnetic field $\vec B$ and noncommutative parameter $\te$. We prove that the degeneracy of Landau levels can be lifted by the $\te$-term appearing in the electron energy spectrum at weak magnetic field. Using the {\it Berezin-Lieb} inequalities for thermodynamical potential, it is shown that in the high temperature limit, the system exibits a magnetic $\te$-dependent behaviour, which is missing in the commutative case. Moreover, a correction to susceptibility at low $T$ is observed. Using the {\it Fermi-Dirac} trace formulas, a generalization of the thermodynamical potential, the average number of electrons and the magnetization is obtained. There is a critical point where the thermodynamical potential becomes infinite in both of two methods above. So at this point we deal with the partition function by adopting another approach. The standard results in the commutative case for this model can be recovered by switching off the $\te$-parameter.

description: Adequate perception of immunologically important pathogen-associated molecular patterns like lipopolysaccharide and bacterial lipoproteins is essential for efficient innate and adaptive immune responses. In the context of Gram-negative infection, bactericidal/permeability-increasing protein (BPI) neutralizes endotoxic activity of lipopolysaccharides, and thus prohibits hyperactivation. So far, no immunological function of BPI has been described in Gram-positive infections. Here, we show a significant elevation of BPI in Gram-positive meningitis and, surprisingly, a positive correlation between BPI and pro-inflammatory markers like TNFα. To clarify the underlying mechanisms, we identify BPI ligands of Gram-positive origin, specifically bacterial lipopeptides and lipoteichoic acids, and determine essential structural motifs for this interaction. Importantly, the interaction of BPI with these newly defined ligands significantly enhances the immune response in peripheral blood mononuclear cells (PBMCs) mediated by Gram-positive bacteria, and thereby ensures their sensitive perception. In conclusion, we define BPI as an immune enhancing pattern recognition molecule in Gram-positive infections.

description: We employ a pair-wise approach to analyse regional integration in the gasoline and ethanol markets in Brazil. Using weekly price data for these two fuels at the state level over a period of almost 10 years, we find that more than half of the fuel price differentials are stationary, which reveals the importance of allowing for spatial considerations when testing for market integration. We find that the speed at which prices converge to the long-run equilibrium depends upon the distance between states and the similarity between tax regimes. Other demand and supply factors such as population density, number of gas stations and GDP per capita are not statistically significant.

description: Trichotillomania (TTM) has shown high rates of comorbidity with ADHD, the symptoms of which have been previously associated with lower quality of life and higher psychopathology severity. While both disorders have been associated with some performance deficits on neuropsychological tasks of motor response inhibition, research on deficits in TTM is inconclusive. Deficits previously found in TTM may be a result of comorbid ADHD as well as failure to compare to healthy controls. Onset of ADHD, an early childhood disorder, could also be associated with an earlier age of onset for TTM than the typical early adolescence. We compared adults with TTM alone (n = 59) and those with TTM and ADHD (n = 60) on measures of TTM severity, quality of life, and age of onset in this fully online study. We predicted that the comorbid group would have an earlier age of onset, higher TTM severity, and lower quality of life. We also compared these groups to a healthy control group (n = 60) on two neuropsychological measures, the Go/No-Go task and the Stop Signal Task, and we hypothesized that those with comorbid TTM and ADHD would have impaired performance relative to TTM alone and healthy controls while TTM alone would not differ from controls. Our results showed that those with TTM and ADHD reported greater TTM severity and lower quality of life relative to TTM alone, but there was no significant difference between the two groups in age of onset and generally nonsignificant differences between the three groups on the neuropsychological tasks. These results did not support the idea of a distinctive presentation of TTM with comorbid ADHD.

 Cophinopoda Hull 1958: 251. Type species: Asilus chinensis Fabricius, 1794, by original designation. Hull 1962: 438; Martin 1964: 306; Oldroyd 1980: 346; Daniels 1989: 333; Tsacas & Artigas 1994: 447; Scarbrough & Hill 2000.
 Diagnosis. In addition to characters in the key, Cophinopoda is distinguished by the large robust body (30+ mm), dense long setae on ventral 1/2 of face, metanotum just above the halter base and posterior corner of scutellum with small tuft of pale setae, shallow preapical scutellar groove, pair of stout anepimeral bristles, and combined characters of the terminalia of both sexes (Figs. 19–23).
 Distribution. Madagascar and nearby islands.
 Remarks. Cophinopoda remains unchanged since its original description. Recent studies have clarified diagnostic characters, added keys, and illustrations of the terminalia (Tsacas & Artigas 1994, Scarbrough & Hill 2000). Presently 5 species are reported (Fig. 107): C. aldabraensis Tsacas & Artigas, 1994 [Aldabra and Cosmoledo Is.]; C. borbonica Tsacas & Artigas, 1994 [Reunion Is.]; C. matilei Tsacas & Artigas, 1994 [Maurice Is.]; C. pulchripes [Madagascar; Aldabra, Comoro Is., Europa Is., Sainte-Marie Is., Seychelles, Yemen (Socotra)], and C. mayottae Bigot, 1859 [Comoro Is.] (Tsacas & Artigas 1994; Londt per. Comm.). None are known from the African continent.

description: We generalize the dominant assurance contract (Tabarrok, 1998) to the threshold public good provision. This contract offers, to donors who agree to a minimum price, an assurance payment as compensation in the event that fundraising fails to achieve the threshold needed to fund the good. We analyze the outcomes when individuals face 1) a minimum price for eligibility for the assurance payment and 2) an assurance payment that differs from the suggested price. We report a field experiment to fund bird habitat in Rhode Island, USA. An increase of assurance payment does not necessarily increase donations; however, for online donation data, we find positive evidence that the assurance payment can increase donation probability. Assurance payments could potentially improve fundraising success and the private provision of public goods.

description: Consumer preferences for labeled products are often assumed to be exogenous to the presence of labels. However, the label itself (and not the information on the label) can be interpreted as a noisy warning signal. We measure the impact of “Contains” labels and additional information about the labeled ingredients, treating preferences for labeled characteristics as endogenous. We find that for organic food shoppers, the “Contains” label absent additional information serves as a noisy warning signal leading them to overestimate the riskiness of consuming the product. Provision of additional information mitigates the large negative signaling effect of the label

description: The earlier an activation of a G protein-dependent signalling cascade at a G protein-coupled receptor (GPCR) is probed, the less amplificatory effects contribute to the measured signal. This is especially useful in case of a precise quantification of agonist efficacies, and is of paramount importance, when determining agonist bias in relation to the β-arrestin pathway. As most canonical assays with medium to high throughput rely on the quantification of second messengers, and assays affording more proximal readouts are often limited in throughput, we developed a technique with a proximal readout and sufficiently high throughput that can be used in live cells. Split luciferase complementation (SLC) was applied to assess the interaction of Gαq with its effector phospholipase C-β3. The resulting probe yielded an excellent Z’ value of 0.7 and offers a broad and easy applicability to various Gαq-coupling GPCRs (hH1R, hM1,3,5R, hNTS1R), expressed in HEK293T cells, allowing the functional characterisation of agonists and antagonists. Furthermore, the developed sensor enabled imaging of live cells by luminescence microscopy, as demonstrated for the hM3R. The versatile SLC-based probe is broadly applicable e.g. to the screening and the pharmacological characterisation of GPCR ligands as well as to molecular imaging.

description: The center of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) hosts a nuclear star cluster, M54, which is the only galaxy nucleus that can be resolved into individual stars at optical wavelengths. It is thus a key target for understanding the formation of nuclear star clusters and their relation to globular clusters. We present a large Multi-Unit Spectroscopic Explorer (MUSE) data set that covers M54 out to $\sim$2.5 half-light radius, from which we extracted the spectra of $\sim$6600 cluster member stars. We use these data in combination with HST photometry to derive age and metallicity for each star. The stellar populations show a well defined age-metallicity relation, implying an extended formation history for the central region of Sgr dSph. We classify these populations into three groups, all with the same systemic velocity: young metal-rich (YMR; 2.2\,Gyr, \mbox{[Fe/H]$=-0.04$}); intermediate-age metal-rich (IMR; 4.3\,Gyr, \mbox{[Fe/H]$=-0.29$}); and old metal-poor (OMP; 12.2\,Gyr, \mbox{[Fe/H]$=-1.41$}). The YMR and OMP populations are more centrally concentrated than the IMR population, which are likely stars of the Sgr dSph. We suggest the OMP population is the result of accretion and merging of two or more old and metal-poor globular clusters dragged to the center by dynamical friction. The YMR is consistent with being formed by in situ star formation in the nucleus. The ages of the YMR population suggest that it may have been triggered into forming when the Sgr dSph began losing its gas during the most recent interaction with the Milky Way, $\sim$3\,Gyr ago.
