Inflation and integrable one‐field cosmologies embedded in rheonomic supergravity

In this paper we show that the new approach to the embedding of the inflationary potentials into supergravity, presented in a quite recent paper [11] of Ferrara, Kallosh, Linde and Porrati can be formulated within the framework of standard matter coupled supergravity, without the use of the new minimal auxiliary set and of conformal compensators. The only condition is the existence of a translational Peccei Quinn isometry of the scalar Kähler manifold. We suggest that this embedding strategy based on a nilpotent gauging amounts to a profound Copernican Revolution. The properties of the inflaton potential are encoded in the geometry of some homogeneous one‐dimensional Kähler manifolds that now should be regarded as the primary object, possibly providing a link with microscopic physics. We present a simple and elegant formula for the curvature of the Kähler manifold in terms of the potential. Most relevant consequence of the new strategy is that all the integrable potentials quite recently classified in a paper [7] that we have coauthored, are automatically embedded into supergravity and their associated Kähler manifolds demand urgent study. In particular one integrable potential that provides the best fit to PLANCK data seems to have inspiring geometrical properties deserving further study.
Identification and molecular analysis of the Leptothrix discophora SS‐1 mofA gene, a gene putatively encoding a manganese‐oxidizing protein with copper domains

A small amount of a manganese‐oxidizing protein was purified from spent culture medium of Leptothrix discophora strain SS‐1 and used to raise antibodies (αMOF). Expression libraries of L. discophora were constructed in λgtll and screened with αMOF. DNA inserts from the resulting αMOF‐positive λgt11 clones were used to isolate the corresponding gene (called mofA) from a genomic library. The mofA gene was mapped in the center of a NcoI‐EcoRI restriction fragment of 7262 bp. This fragment was cloned in a low‐copy broad‐host vector. The resulting plasmid (pGBM31) was used in an in vitro transcription‐translation experiment with an Escherichia coli S30 extract. Transcription of the mofA gene could be initiated on its own putative promoter region. Translation resulted in a protein of approximately 180 kD as determined by gel electrophoresis. DNA sequence analysis revealed an open reading frame of 4986 bp preceded by a potential promoter region and a ribosome binding site. The translation product, consisting of .
Morphology and growth characteristics of Chrysochromulina species (Haptophyceae = Prymnesiophyceae) isolated from New Zealand coastal waters

Abstract Chrysochromulina acantha, C. hirta, C. pachycylindra, and C. cf. polylepis (Haptophyceae = Prymnesiophyceae) are new records, based on transmission electron microscopy, for New Zealand coastal waters. The morphology and growth characteristics of C. acantha and C. hirta, and of C. simplex and C. ericina (also New Zealand isolates), are described. C. ericina of the present study has a shorter haptonema (12–24 urn; non‐coiling), larger plate and spine scales, and fewer spine scales (with broader bases), than northern hemisphere isolates. Scales of C. simplex fit the emended type description, whereas the large spine scales of C. hirta are shorter (≤ 11 μm) than the type description (20–30 μm). C. ericina and C. hirta fall into a temperate (15–20°C), and C. acantha and C. simplex into a sub‐tropical (20–25°C), temperature group. All species tested grew well in brackish salinities (c. 23 through to 36); C. hirta grew optimally at a salinity of 23. All tolerated 25–150 umol m−2 s−1 photon flux and pH of.
Day Length and Temperature Strongly Influence Sexual Reproduction and Expression of a Novel MADS‐Box Gene in the Moss Physcomitrella patens

: The effect of temperature and light conditions on sexual reproduction (sporophyte formation) of in vitro cultures of the moss Physcomitrella patens was analysed. All parameters tested, i.e., temperature, light intensity and day length had a strong impact on the number of sporophytes formed. The highest number of sporophytes, 559 g fresh weight, developed at 15 °C, 8 h light/day with an intensity of 20 μmol/m2/s. In contrast, at 25 °C, as well as with a day length of 16 h per day, the number of sporophytes was drastically reduced. Vegetative growth, determined as fresh weight per petri dish, was impeded under conditions favouring sporophyte formation, probably due to nutrient transfer to the sporophytes. Microscopic documentation of the developing sporophytes revealed that, although archegonia were arranged in bundles at the gametophore apices, usually only one archegonium per gametophore apex developed into a mature sporophyte. From an EST database six novel MADS-box genes were identified which, in phylogenetic analyses, did not cluster with the known groups of higher plant MADS-box genes. One of these genes was represented only as a singleton in a cDNA library specifically derived from gametophore apices and developing sporophytes, and, therefore, designated PpMADS-S. RNA amounts of PpMADS-S were two to three times higher under conditions that stimulate sporophyte development (15 °C, 8 h light per day) when compared to conditions favouring vegetative growth (25 °C, 16 h light per day), indicating a possible function in sexual reproduction of this moss. Thus, an efficient experimental system was established to study sex organ formation, fertilization and embryo development in Physcomitrella.

An analytic semigroup for the magnetoelastic Mindlin–Timoshenko plate model

Along with the development of magnetoelastic sensor technology, the subject of magnetoelastic vibrations in plates has attracted considerable interest during the past few decades. More recently, models for the magnetoelastic interactions of a Mindlin–Timoshenko plate and a magnetic field in an electrically conducting plate have been investigated by Grobbelaar-Van Dalsen in [Grobbelaar-Van Dalsen M. On the dissipative effect of a magnetic field in a Mindlin–Timoshenko plate model. Z. Angew. Math. Phys. 2012;63:1047–1065] and [Grobbelaar-Van Dalsen M. Exponential stabilization of magnetoelastic waves in a Mindlin–Timoshenko plate by localized internal damping. Z. Angew. Math. Phys. 2015;66:1751–1776]. In the cited contributions, we accomplished, respectively, polynomial stability of the model, with no mechanical damping, and exponential stability of the model, equipped with nonlinear locally distributed damping that exhibits linear behaviour near the origin. In this article, we complete the cycle by showing that inclusion of Kelvin–Voigt damping in the interior of the plate furnishes the property of analyticity of the semigroup of contractions associated with the model. This provides a direct route to the exponential uniform stability of the model.
A Longitudinal Study of the Self-Concept and Experiential Components of Self-Worth and Affect Across Adolescence

Classic theories depict adolescence as a period of emotional "storm and stress. " Empirical evidence, mostly from cross-sectional studies, suggests that emotional development presents a mixture of continuity, swings, and resilience. We examined longitudinally the average grade trends in components of self-concept and experiential components of self-worth and affect across adolescence. We followed 1,165 6th through 12th graders for 4 years using a 3-wave, accelerated longitudinal design. Participants completed self-concept scales (global self-esteem and locus of control), and the Experience Sampling Method, which provided daily self-reports on self-worth (living up to one's own expectations, to the expectations of others, feeling successful, and feeling in control of the situation) and affect (feeling good about oneself and feeling happy). Multilevel modeling indicated that both self-esteem and locus of control grow linearly over time. Self-worth components of experience showed a concave-up trend bottoming around Grade 10, suggesting a pubertal swing and partial readjustment by the end of adolescence. Affect declined quadratically across adolescence. Compared to White students, less positive grade trends were found for Hispanics, Asian Americans, and adolescents from nontraditional families. A mixed pattern emerged for African Americans. Behind the stable growth of components of self-concept, adolescents experience a certain degree of discontinuity as to how they evaluate their capability to meet everyday life demands and their affect declines. The modifications in grade trends due to ethnicity and family structure call for studies on the possible influence exercised by family processes and school environments.
Methods for assessing social status in Arctic charr

The aggression index is a more reliable method for assessing the social status of Arctic charr Salvelinus alpinus held in small groups, than is food intake or position relative to a defensible food resource. However, care must be taken when assigning rank, as all three of these commonly used methods can result in different social ranks for an individual fish.
Supercritical CO2 extraction of grappa volatile compounds

Summary A first study on the recovery of aromatic extracts from grappa by means of supercritical fluid extraction (SFE) on a laboratory plant has been performed, to obtain aroma extracts at low ethanol content. The influence of extraction parameters like pressure, temperature and flow rate have been studied. Extraction yields have been evaluated for ethanol, higher alcohols and esters of short and medium chain acids. A higher aroma volatile compounds extraction has been obtained when the strongest extraction condition has been considered (200 bar, 60 °C, 0.3 kg h−1). Sensory evaluation has indicated as preferred the extract obtained under mild condition (80 bar, 40 °C, 0.3 kg h−1).
On the long memory properties of emerging capital markets: evidence from Istanbul stock exchange

This paper analyses long memory properties of Istanbul Stock Exchange Market (ISE) National 100 daily dollar index returns, absolute and squared returns. Both parametric FIGARCH models and nonparametric methods are employed. Results indicate that, contrary to empirical evidence on some other emerging capital markets, daily returns do not possess long memory characteristics, however, similar to developed equity markets, evidence is provided of long memory dynamics in the conditional variance which can be modelled adequately by a FIGARCH model.
Selection of Arthrospira platensis strains with productivity in brackish water with high boron levels for commercial production in the Lluta Valley

Adaptation and selection of Arthrospira platensis strains, for cultivation in brackish water with excess boron (B) in the Lluta Valley can become an interesting alternative that would allow to extend these cultures to areas that possess the environmental conditions, but that lack the fresh water needed to do it. Strains TX98 and P88 were evaluated in laboratory conditions with three different media of brackish water and with the white medium, the Zarrouk modified medium (MZM). The growing media with brackish water with a B concentration present in the Lluta River of 20 mgL -1 (B20) and medium with 30 mgL -1 (B30), and 10 mg L -1 of B (B10). The effect of the different media on the growing parameters with a culture temperature of 25 ± 1oC in the three treatments, strains TX98 and P88 triplicate, Arthrospira platensis , showed tolerance. It was statistically determined that in the growth, the two strains, the three treatments and in the interrelation of both there were significant differences (p -1 (dry weight) in brackish water with medium B20. Therefore, the highest rate of specific growth (μmax) was obtained with the TX98 strain grown in the brackish medium B30 and the lowest duplication time (0.597 days). Cells grown in brackish water with B had a slightly biochemically modified composition with the white, in relation to the protein content, in the cases in which there are differences in the B content, specifically B30 treatment. For the culture with brackish water from the Lluta River, the TX98 strain is recommended with 10 mg of B using a laboratory to pilot scale.
PHOTOSYNTHETIC CHARACTERISTICS OF THE COCCOLITHOPHORID EMILIANIA HUXLEYI (PRYMNESIOPHYCEAE) EXPOSED TO ELEVATED CONCENTRATIONS OF DISSOLVED INORGANIC CARBON 1

Light‐saturated photosynthesis (Pmax) of Emiliania huxleyi (Lohmann) Hay et Mohler is known to be carbonlimited at natural concentrations of dissolved inorganic carbon (DIC). In the present study, light‐limited and light‐saturated photosynthetic rates of E. huxleyi were studied at three concentrations of DIC (2.4, 7.4, and 12.4 mM) for high‐calcite (Cin/Ctot=0.48) and low‐calcite (Cin/Ctot=0.08) cells of the same strain. The photosynthetic efficiency (α) and the maximum quantum yield (θmax)A increased by more than a factor of 2 from the lowest to the highest DIC level. Pmax a, and θmax were always higher for the high‐calcite than for the low‐calcite cells at identical DIC levels. This may indicate that the calcifcation process acts as an extra supplier of CO2 for photosynthesis making the CO2 shortage at natural DIC levels a little smaller for high‐calcite than for low‐calcite E. huxleyi. A dependency of θmax on DIC has not previously been shown for marine phytoplankton. θmax is a key parameter in recent biooptical models of phytoplankton productivity, and the results from the present study are therefore important for modeling the productivity of E. huxleyi.
Starch hydrolytic enzyme activities following defoliation of white clover

White clover (Trifolium repens L.) is an important legume in grassland ecosystems. Its persistence in mixed grass-clover swards, however, is dependent on utilization of stored carbohydrates during over-wintering and subsequent spring regrowth. Reserve carbohydrate is stored as starch in stolons. Our objective was to determine how activities of starch hydrolytic enzymes change during defoliation-induced starch mobilization in clover stolons. Starch degradation was induced by defoliating clonally propagated plants maintained in a controlled environment. Defoliation resulted in rapid, extensive starch remobilization from older stolon tissues, and prevented starch accumulation in young, developing stolon tissues. Amylase activities of stolon tissue were determined immediately, 1, 2, 4, 8, and 12 d post-defoliation. Total amylolytic activity decreased following defoliation. Of the starch hydrolytic enzyme activities determined, only the activity of α-amylase increased as a consequence of defoliation two-fold, with respect to the control). β-amylase, which constituted the greatest proportion of total amylolytic activity, decreased two- to three-fold in stolons of defoliated plants, but increased six-fold in young stolon tissue, and almost two-fold in old stolon tissue. The increase in enzyme activity correlated with starch deposition in control plants. Starch phosphorylase activity also decreased as a result of defoliation, while activity of α-glucosidase changed little following the defoliation treatment. Our results suggest starch degradation in stolons of white clover is regulated by α-amylase activity.
Bionomics of Alloxysta pleuralis, a cynipoid hyperparasitoid of an aphidiid parasitoid Trioxys indicus

Alloxysta pleuralis parasitizes the larvae of Trioxys indicus, a parasitoid of Aphis craccivora. Either of the sexes of this hyperparasitoid (A. pleuralis) was ready to mate shortly after emergence. During courtship the females carried the males on the top of her back for 2 – 3 min. Although the hyperparasitoid is obligatory, a similar, typical oviposition exploration pattern takes place on healthy aphids, however, then the eggs are laid only in parasitized aphids in the haemocoel of the larvae of the parasitoid. The life‐cycle takes about a month. Superhyperparasitism was commonly observed. Adults survived for 4–13 days.
Genetic Redundancy and Diversity among ‘Orange’ Accessions in the U.S. National Sorghum Collection as Assessed with Simple Sequence Repeat (SSR) Markers

Plant genetic resources conservation is a challenge based on the need to balance acquisition priorities with the constrained level of financial support that is dedicated to long-term malntenance of collections. As such, understanding how variation is partitioned among accessions is essential for effective management. It is generally recognized that most large collections exhibit varying levels of genetic redundancy. To address this issue, all of the sorghum [Sorghum bicolor (L.) Moench] accessions identified as 'Orange' presently maintained by the U.S. National Plant Germplasm System (NPGS) were assayed with 15 simple sequence repeat (SSR) markers. Genotyping was performed with fluorescent primers with five primer sets in each of three multiplex polymerase chain reactions (PCRs) and automated allele sizing. A total of 96 individuals were analyzed, five plants from each of 19 Orange accessions and one individual from an elite inbred line, RT×430'. The SSR markers provided substantial genetic resolution among the Orange entries. Average heterozygosity estimates were low, and phenetic analyses (neighbor-joining dendograms) were generally consistent with known historical relationships among accessions. Most accessions were genetically distinct, but two redundant groups (involving a total of five entries) were found among the 19 Orange accessions evaluated. The molecular variance analysis (AMOVA) showed that 90% of the total genetic variation was partitioned among accessions, while one-tenth of the variation resulted from genetic differences between individual plants within accessions. The variance analysis also indicated that it should be possible to reduce the number of Orange accessions held by NPGS by almost half without seriously jeopardizing the overall amount of genetic variation contained in these holdings. This study demonstrated that a limited number of SSR markers can be used in a cost-efficient manner to rapidly assess variation in accessions of Orange sorghum.
THE COASTAL-ESTUARINE COPEPOD, EURYTEMORA AFFINIS (POPPE) (CALANOIDA, TEMORIDAE), FROM ARID INLAND AREAS OF MEXICO: AN EXPECTED OCCURRENCE?

For decades, the coastal-estuarine copepod, Eurytemora affinis (Poppe, 1880) was considered a cosmopolitan species. Recent studies have demonstrated that it represents a species complex with static morphology but with genetically recognizable forms clustered in defined geographical patterns. In North America, this species is widely distributed in coastal environments, but has been known to also colonize freshwater systems along the eastern coast of the United States and Canada. Based on serial samples collected in the Chihuahuan Desert (2003-2006) and in the State of Tamaulipas (2000-2002), in this work we report the occurrence of this coastal copepod from arid and semi-arid continental systems of northern Mexico and the southwestern United States. All records are from areas well inland: 800 km from the coast in the Chihuahuan Desert and 240-250 km in Tamaulipas. Records from these particularly dry, isolated habitats illustrate the adaptive performance of this species, which enables it to dwell in such extreme conditions. This is the first record of E. affinis from Mexico and also the southernmost one in the Americas as a freshwater form. Illustrations and morphometric data of specimens obtained in these arid and semi-arid zones are provided. The size, general morphology, and morphometry of these specimens show similarities to different sub-groups known within the species range, but some characters and ratios are outside of the known patterns, thus expanding the morphometric spectrum of this species. Hitherto, the only other finding of an estuarine coastal calanoid copepod in epicontinental freshwater environments in Mexico is that of Pseudodiaptomus marshi Wright, 1936 on the Yucatan Peninsula.
The impact of a ‘soda tax’ on prices: evidence from French micro data

ABSTRACT Based on an original data set of more than 500,000 non-alcoholic beverage price records, we evaluate the impact on consumer prices of the ‘soda tax’, an excise on drinks with added sugar or sweetener, introduced in France in January 2012. We adopt a difference in differences approach and find that the tax was gradually passed through to the prices of the taxed beverages. After 6 months of its introduction, it was fully shifted to soda prices and almost fully shifted to the prices of fruit drinks, while the pass-through for flavoured waters was incomplete. We also find that the pass-through was heterogeneous across brands and retail groups.
THE ECOLOGY OF DISCOLOURED WOOD AS ILLUSTRATED BY BEECH (FAGUS SYLVATICA L.)

Summary Association between dehydration and discol ouration was demonstrated by artificial intro duction of discolouration on the ripe (mature) wood of stern and branch discs. The absolute extent of the dehydrated zone and red heart in creases with increasing diameter and height, to gether with simultaneous crown reduction. The relative extent of the dehydrated zone and red he art depends mainly on the live crown ratio and stern radius. Accordingly, factors condu cive to red heart formation are fast growth and intensive crown reduction. In dense stands on fertile soils red heart is expected at approx. 80 years. On the other hand the dehydration and discolouration in slow growing trees on poor soiIs with low crown in hardly cIosed stands, e.g. at the timber line or in thin suppressed specimens with drying crowns, on otherwise good soiIs, is retarded (red heart-formation at ISO years or later).
Deconstructing CHC

ABSTRACT Twenty-five years after the introduction of Carroll’s (1993) Three Stratum (3S) theory of intelligence and McGrew’s (1997) subsequent synthesis of 3S with the extended Gf-Gc / Horn-Cattell theory, the Cattell-Horn-Carroll (CHC) theory represents the prevailing framework by which the structure of human cognitive and intellectual abilities is understood. This commentary reviews, discusses, and supplements the critical examinations of CHC theory appearing in this special issue of Applied Measurement in Education. After recounting the historical foundations and structural framework of CHC, a series of challenges to this theory are compiled including its weak explanatory capacity, its failure to make testable predictions, its enmeshment with a single measurement instrument (i.e., the Woodcock–Johnson), the inconsistent independent replication of its factor structure, and most importantly, its undemonstrated evidential value for identification and intervention with students with specific learning disorders (SLDs). The inherent limitations of any psychological theory developed or tested primarily from factor analyses are enumerated. Solutions are proposed to advance psychological science in areas related to CHC theory.
Volatility links between US industries

This article investigates volatility linkages across 30 US industries in terms of volatility leadership impact and interdependence dynamics. The volatility spillover index of Diebold and Yilmaz (2009) is used to uncover industries that show leadership in volatility and to measure the impacts of leading industries on lagging industries. I find that a leader is also a follower, which results into a web of complex relationships in volatility spillovers. Nevertheless, I identify the business equipment, the manufacturing and the financial intermediation industry as the main leading industries through which the entire economic system can be either stimulated when the economy is contracting or cooled when the economy is expanding.
