On certain zeta integral: Transformation formula
Creators: name: Espinoza, Milton

Year: 2020
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: We introduce an "$L$-function" $\mathcal{L}$ built up from the integral representation of the Barnes' multiple zeta function $ζ$. Unlike the latter, $\mathcal{L}$ is defined on a domain equipped with a non-trivial action of a group $G$. Although these two functions differ from each other, we can use $\mathcal{L}$ to study $ζ$. In fact, the transformation formula for $\mathcal{L}$ under $G$-transformations provides us with a new perspective on the special values of both $ζ$ and its $s$-derivative. In particular, we obtain Kronecker limit formulas for $ζ$ when restricted to points fixed by elements of $G$. As an illustration of this principle, we evaluate certain generalized Lambert series at roots of unity, establishing pertinent algebraicity results. Also, we express the Barnes' multiple gamma function at roots of unity as a certain infinite product. It should be mentioned that this work also considers twisted versions of $ζ$.

description: In order to investigate ecological adaptation mechanism of bryophyte, two dominant mosses Thuidium cymbifolium and Mnium immarginatum in Baotianman Nature Reserve were measured the content of C, N, P and their ratio in bryophyte and soil , and and analyzed the relationships of plant and soil ecological stoichiometric characteristics along altitudinal gradients. Results indicate that the content of C, N and P in green tissues of T. cymbifolium and M. immarginatum in Baotianman Nature Reserve was 46.81%-49.09%, 0.21%-0.25%, and 0.02%-0.08%. Among the different altitudinal gradients, C, N and P displayed significant differences: the significantly different content of C and N were showed in T. cymbifolium, and the content of N and P differed significantly in M. immarginatum. However, only N declined obviously as increasing altitude. In soil, the C, N, N/P and C/P showed an increasing trend with increasing elevation, while the P and C/N along altitudinal gradients were not exhibited unified trends. With the increasing in the content C, N of soil, the content C and N of T. cymbifolium raised, while the content C and N of M. immarginatum declined. With the rise in P element of soil, N/P showed different trends between two bryophyte species, the N/P in T. cymbifolium significantly decreased, while N/P in M. immarginatum significantly increased. In addition, mean value of leaf N/P was 8.51, ranking 14-16. These results suggested that the growth of the bryophyte plants in Baotianman Nature Reserve were restricted by N element, and different utilization strategies in soil P element in different bryophyte plants led to differences in ecological stoichiometric characteristics Bryophyte, Soil nutrients, Stoichiometric, Baotianman Nature Reserve, Altitude gradients 12 A Study of Adsorption of Modified Corn Stalk on PCP The comprehensive utilization of corn stalks is an urgent agricultural and environmental problem to be solved in China. In this test, we use corn stalk as adsorbent for adsorption of PCP in water, and compare the impact of three modification methods (alkali treatment, pyrolysis, graft copolymerization) on corn stalk adsorption properties. Results show that the modified corn stalk's adsorption of PCP is increased from 5.4 mg/g to 13.9 mg/g, 17.8 mg/g and 22.5 mg/g, respectively; the corn stalk after graft copolymerization and modification has the greatest adsorption capacity; after modification, both the adsorption capacity and adsorption rate constant of corn stalk on PCP are increased significantly.

description: We present a theory of one-neutron halo breakup reactions within the framework of post-form distorted wave Born approximation wherein pure Coulomb, pure nuclear and their interference terms are treated consistently in a single setup. This formalism is used to study the breakup of one-neutron halo nucleus 11Be on several targets of different masses. We investigate the role played by the pure Coulomb, pure nuclear and the Coulomb-nuclear interference terms by calculating several reaction observables. The Coulomb-nuclear interference terms are found to be important for more exclusive observables.

Assessing market (dis)integration in early modern China and Europe
Creators: name: Bernhofen, Daniel
Publisher: name: American University
Year: 2023

description: This paper challenges established claims of comparable degrees of market integration in Europe and China on the eve of industrialization. Our empirical strategy focuses on the dynamics of price convergence and accounts for general equilibrium effects arising from common shocks and network effects. Using monthly grain prices for 1740-1820 our analysis uncovers a secular process of market disintegration in 221 prefectures of Qing China. Comparing our results with those for grain price panels from Western Europe we conclude that in terms of market integration the Great Divergence was well under way decades before the start of the 19th century.

Thermal Hall effect in the pseudogap phase of cuprates
Creators: name: Varma, Chandra M.
Publisher: name: arXiv
Year: 2020
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The conjecture made recently by the group at Sherbrooke, that their observed anomalous thermal Hall effect in the pseudo-gap phase in the cuprates is due to phonons, is supported on the basis of an earlier result that the observed loop-current order in this phase must induce lattice distortions which are linear in the order parameter and an applied magnetic field. The lowered symmetry of the crystal depends on the direction of the field. A consequence is that the elastic constants change proportional to the field and are shown to induce axial thermal transport with the same symmetries as the Lorentz force enforces for the normal electronic Hall effect. Direct measurements of elastic constants in a magnetic field are suggested to verify the quantitative aspects of the results.

description: IR theories of diplomacy tend to focus on how diplomats make gains at the expense of their counterparts. However, modern diplomatic bargains sometimes hinge more on making them palatable to the domestic publics of the negotiating states. In this paper I draw on Erving Goffman’s concept of ‘impression management’ to explain how diplomats sometimes collude against their own publics in order to strike deals. I analyze the diplomacy of the Iranian Hostage Crisis of 1979-1980. During this crisis senior regime officials from the US and Iran colluded in the construction of a theatrical ‘scenario,’ in which both sides adopted roles and played their parts in the hope that this could satisfy the sentiments of both US and Iranian domestic publics. I argue that the scenario failed due to insufficient teamwork and an unsympathetic audience. In making this argument I challenge common assumptions about the adversarial nature of diplomacy, and the role of domestic audiences in diplomatic outcomes.

description: To grasp protein content and composition of pea resource in Tibet Plateau, 54 pea materials from different eco-geographical environments of Tibet were collected and arranged in this paper. Based on SDS-PAGE, electrophoresis and genetic diversity analysis of water-solubility and salt-solubility proteins from 54 pea materials were conducted, and the relationship between geographical ecological factors（longitude, latitude and altitude）and total protein content was studied. The research results showed that total protein contents of 54 pea materials were between 17.58% and 28.67%, in which water-solubility protein accounted for 86.12%-91.40%, while salt-solubility protein accounted for 4.76-8.29%. Total protein content of Tibet pea showed significantly positive correlation with longitude, certain positive correlation with latitude and certain negative correlation with altitude. SDS-PAGE of water-solubility and salt-solubility proteins from 54 pea materials respectively detected 1588 and 699 protein bands. Based on different mobility ratios, there were 43 kinds of water-solubility protein bands, and diversity index was between 0 and 0.5. Its relative molecular weight was between 24.87 and 149.54 ku, showing the low molecular weight region of 24.71-50.41 ku and high molecular weight region of 56.34-88.08 ku. There were 24 salt-solubility protein bands based on different mobility ratios, with the diversity index of 0-0.5, and relative molecular weight was between 24.85 and 91.24 ku. According to the altitude, 54 pea resources were divided into 4 geographical groups. Gene diversity indexes of each group were respectively 0.23, 0.18, 0.35 and 0.31, and Shannon information indexes were respectively 0.33, 0.41, 0.52 and 0.46. It showed that the variation of pea protein was related to altitude. In clustering analysis, the tested resources were divided into seven classes, showing that water-solubility and salt-solubility proteins could reflect genetic relationship among germplasm resources at certain degree. The research could provide theoretical basis for the development of Tibet pea resources and selection of good parents.
Charged Rotating Black Hole Formation from Thin Shell Collapse in Three Dimensions

description: The thin shell collapse leading to the formation of charged rotating black holes in three dimensions is analyzed in the light of a recently developed Hamiltonian formalism for these systems. It is proposed to demand, as a way to reconcile the properties of an infinitely extended solenoid in flat space with a magnetic black hole in three dimensions, that the magnetic field should vanish just outside the shell. The adoption of this boundary condition results in an exterior solution with a magnetic field different from zero at a finite distance from the shell. The interior solution is also found and assigns another interpretation, in a different context, to the magnetic solution previously obtained by Clément and by Hirschmann and Welch.

title: Interests Informing Dutch Parents' and Teachers' Positioning in their Collaborative Relations
Creators: name: Klapwijk, G. J.
Publisher: name: The Open University
Year: 2019

description: To benefit the schooling and development of a child, the relationship between parents and teachers is considered to be crucial in improving social and academic outcomes. Dutch education policy aims to encourage collaborative parent–teacher relations. However, in practice, this seems to be complex. Evaluations of partnership practices in Dutch education have concluded that more action is needed to develop a collaborative culture. This empirical study aimed to contribute to the existing literature by investigating 1) how conflicting positionings inform parents’ and teachers’ collaborative relations and 2) how the transactional positioning of parents and teachers has an impact on possible conflicts and tensions in interaction. The theoretical framework of ‘transactional positioning’ developed for this research draws upon positioning theory, role theory, and the concepts of agency and transaction. A pragmatic approach was adopted and a mixed methods study designed to provide further insight into the positioning of parents and teachers in their relationship. The sample consisted of 367 parents and 80 teachers sourced from five different urban Dutch schools. A questionnaire and group interviews provided interesting insights into the role conceptions and positioning of parents and teachers. The data revealed how strained relations seem to hinder parent–teacher relations and how parents and teachers seem to be located based on the ambivalent ways in which they position themselves. Individual reflections and assessments guide their positioning rather than mutual coordination of the development of their relationship. The framework of transactional positioning provides a useful tool for further research into positioning practices in educational and other areas. The findings of this research have the potential to inform policy and develop practices in schools. This research contributes to new knowledge on parent–teacher relations by revealing the conflicting interests of parents and teachers and providing insight into the transactional nature of positioning in practice.

It is a dG9 spectral type star whose rotational period and X-ray luminosity make it a supersaturated star. Our X-ray observation, made with EPIC/PN on XMM-Newton, covers about two photometric rotational periods. The detection of rotational modulation implies the presence of structural inhomogeneities. Possible interpretations are presented and discussed.

description: A special class of anisotropic media, hyperbolic metamaterials and metasurfaces (HMMs), has attracted much attention in recent years due to its unique abilities to manipulate and engineer electromagnetic waves on the subwavelength scale. Because all HMM designs require metal dielectric composites, the unavoidable metal loss at optical frequencies inspired the development of active HMMs, where gain materials is incorporated to compensate the metal loss. Here, we experimentally demonstrate an active type II HMM that operates at vacuum wavelength near 750 nm on a silicon platform. Different from previous active HMMs operating below 1 μm, the dielectric constituent in our HMM is solely composed of gain medium, by utilizing solution processed and widely tunable metal halide perovskite gain. Thanks to the facile fabrication, tunability and silicon compatibility of our active HMM, this work paves the way towards HMM's integration into on chip components, and eventually, into photonic integrated circuits.

Leptodactylidae

description: Family Leptodactylidae   The species formerly known as Leptodactylus ocellatus (Linnaeus, 1758) is currently called L. latrans. According to Lavilla et al. (2010), the name Rana ocellata Linnaeus, 1758 does not represent a leptodactylid, but the Jamaican hylid Osteopilus brunneus (Gosse, 1851), and the oldest available name for the taxon then known as Leptodactylus ocellatus is Rana latrans Steffen, 1815.
 Nascimento et al. (2006) has shown that the correct name of the species to which the name Physalaemus fuscomaculatus (Steindachner, 1864) used to be formerly applied is P. marmoratus. Currently, Eupemphix fuscomaculatus Steindachner, 1864 is considered a junior synonym of Physalaemus biligonigerus Cope, 1861 (see Kolenc et al., 2011), a species that does not occur in Rio de Janeiro (Frost, 2017).
 Langone et al. (2015) reviewed the distribution range of Pseudopaludicola falcipes (Hensel, 1867) and concluded that this species is restricted to northern Argentina, Uruguay, and the extreme south of Brazil, with all previous Brazilian records outside that range (including those from Rio de Janeiro state) representing misidentifications. Therefore, we remove P. falcipes from the list of amphibians of Rio de Janeiro, observing that the identity of the Pseudopaludicola species occurring in the state is presently unknown, which we acknowledge by listing it as Pseudopaludicola sp.

For this study, seven lines of sunflower were tested with three testers 7x3 of sunflower to obtain twenty one F1 genotypes from Line X tester mating design. It was concluded from present study that among the lines, 0505 Cms-6, Peshawer-93 Cms-11, Peshawar-93 Cms-12 were the best general combiners to play the vital role in flowering, maturity, plant height, head diameter, seed index, grain per head and 100-grain yield per plant. While RHP-53, RHP-42, RHP-46 were also the best combiners for all the traits. However, hybrid 54CMS-1 x RHP-42 showed best specific combiners, while Peshawer-93 exhibited good specific combiners for grain yield per plant, the hybrids, plant height, head diameter, seed index, grain per head and grain yield per plant, respectively. Significant differences among the tested sunflower genotypes with regard to mean values of all the investigated traits were determined. The analysis of variance of combining abilities and the analysis of genetic variance components confirmed the non-additive component.

description: Family Microhylidae   Peloso et al. (2014) synonymized the genus Syncope Walker, 1973 with Chiasmocleis Méhely, 1904, thus creating an instance of homonymy between Chiasmocleis carvalhoi (Nelson, 1975) (formerly in the genus Syncope) and Chiasmocleis carvalhoi Cruz,Caramaschi & Izecksohn, 1997. To solve the problem Peloso et al. (2014) renamed the latter species (i.e., the junior homonym) as C.lacrimae.
 Silveira et al. (2010) reported the first record of Elachistocleis ovalis (Schneider, 1799), and also of the genus Elachistocleis Parker, 1927, for the state of Rio de Janeiro, based on a specimen from the municipality of Itaperuna. Caramaschi (2010) considered E. ovalis a nomen dubium, and identified all specimens of Elachistocleis examined by him from the state of Rio de Janeiro (including the specimen reported by Silveira et al., 2010) as E. cesarii, a species that had just been revalidated by Toledo et al. (2010) for specimens from the state of São Paulo. Thus, the species of Elachistocleis occurring in Rio de Janeiro is currently referred to E.cesarii.
 The records of Stereocyclops incrassatus Cope, 1870 in the state of Rio de Janeiro are currently considered to represent S. parkeri (see Frost, 2017). Previously in the synonymy of S.incrassatus (see Carvalho, 1948), S. parkeri was treated as a valid taxon by Bokermann (1966) without comment, and this has been followed by most subsequent authors since then (e.g., Izecksohn & Carvalho‑e‑Silva, 2001; Haddad et al., 2013).

We show that radiation friction can cause a superradiation pulse and investigate the role of magnetic anisotropy, external magnetic field and dipole-dipole interactions. Depending on the contribution of all these factors at low temperature, several regimes of magnetization of crystal sample are described. Very fast switch of magnetization's direction for some sets of parameters is predicted.

description: Norma Broude, professor emerita of art history, American University. To celebrate the closing day of its Degas/Cassatt exhibition, October 5, 2014, the National Gallery of Art hosted a public symposium titled Degas and Cassatt: Different Perspectives featuring conservators, curators, and scholars. On view beginning May 11, the exhibition focused on how the relationship between American Mary Cassatt (1844–1926) and Frenchman Edgar Degas (1834–1917) influenced their artistic practices and careers. Cassatt, who had settled in Paris in 1874, first met Degas in 1877. Over the next decade, the two artists engaged in an intense dialogue, turning to each other for advice and challenging each other to experiment with materials and techniques. Both made printmaking an important aspect of their careers and for a time collaborated on their endeavors. Their admiration and support for each other endured long after their art began to head in different directions: Degas continued to acquire Cassatt’s work, while she promoted his to collectors back in the United States. They remained devoted friends for 40 years, until Degas’s death.

description: The toric manifolds in question were invented by Bott and studied by Grossberg and Karshon under the name "Bott towers". Interest in them comes from their relation to characters of semisimple Lie groups and geometric quantization. We offer another construction of them, introduce a family symplectic structures as curvatures of line bundles, work out canonical coordinates (action-angle variables), derive positivity criteria for the curvature, and determine the range of the moment map. A character of the torus group is introduced as an integral in the spirit of Kirillov's character formula and shown to equal the sum over the integral points in the moment polytope by methods from convex analysis and equivariant cohomology. The result is compared with an explicit calculation of a path integral, based on a definition devised for the occasion.

description: With slow economic growth following the 1990-91 recession and with small price increases, food spending rose to $617 billion in 1993 (table 1). This 3.7-percent increase is more than twice that of 1992. Food away from home led the increase, rising 5.5 percent in 1993, and food at home rose 2.2 percent. Adjusted for inflation, food spending per person rose 0.5 percent in 1993-food at home went down 1.2 percent and food away from home rose 2.5 percent- following 2 years of modest declines (table 2). As the Nation struggled out of the recession, personal food spending increased less than that for most other major categories of personal consumption, as is typical (table 3). Federal, State, and local governments paid for a slightly larger share of food in 1993, up 0.1 percent to 5.8 percent. Most of the increase was due to expanding Federal food assistance programs--notably food stamps, as participation increased with persistent unemployment. Price increases were modest-as they had been in 1992---due to ample supplies. Vigorous competition among food retailers and among restaurants helped moderate the price increases
title: Venture capital in the UK: A regional deal?
Creators: name: Parris, Stuart James
Publisher: name: The Open University
Year: 2009

description: In this thesis we examine the organisation of the UK venture capital industry. We draw on literature from finance, innovation and economic geography in order to build a model to understand the relationship between the distribution of investment and regional resources. Using network theory we then extend this model in order to understand the structure of ties between actors in the venture capital investment process. Thus, we analyse the relationship between regional venture capital activity in the UK and a range of relevant regional resources. The thesis argues that patterns of investment activity in the UK are well established, with well defined regional concentrations, resulting from the geographically-embedded nature of venture capital. However, at a sector level, regional relationships between local resources and investment vary. We find that investment in biotechnology is less regionally embedded and strongly influenced by changes in local resources, such as R&D. Although we demonstrate venture capital networks operate at a national level, our network analysis shows that regional variations persist in the strength and quality of relationships between investors and entrepreneurial directors. Consistent with a regionally embedded venture capital industry, and in agreement with social capital theory, our analysis indicates distinctive regional network patterns which support local investment activity. This thesis supports a regional innovation systems approach where the investor plays an important role in defining the system. However, we emphasise that individual regions may adopt different systems with regards to the presence and operation of venture capital, as a result of the distinctive characteristics of each region, their history, proximity to London and the structure of social networks. We suggest that policy can play a role in supporting these systems if it is sensitive to the variation in regional dynamics and takes account of access to entrepreneurial resources located outside the region.
Presenting the Unknown: infrastructure, influence and information in the management of uncertain objects in museums and galleries

Subjects: Uncategorized

description: This thesis examines unknown objects and their associated information in collections across institution types including history, art, and science. Unknown objects are defined as those with uncertain or unknown core record elements. As both outliers and unexpectedly representative subjects of collections and their management, unknown objects provide the unique lens through which this cross-disciplinary study is conducted. Comparative case studies at the National Portrait Gallery, V&A Museum, British Museum, Pitt Rivers Museum, Natural History Museum and Science Museum provide foundations for methods and analysis through the examination of unknown objects, collections records, and interviews with personnel.
This research project illuminates the effect of museum and gallery systems on the creation and maintenance of ‘unknownness’ in collections both on and off display.
Specific reasons for unknowns vary by case. However, this project argues that the networked interactions between objects, records, industry standards, and institutional systems and histories characterise the unknown in museum and gallery environments universally. Within these networked interactions, common influences (such as the separation of collections and documentation) and themes (such as searchability) are at the core of unknownness in collections and serve as the framework for this thesis.
This study addresses a gap in research of the systems that manage museums and galleries as caretakers of not only objects, but also information, and elucidates relationships between the unknown, and knowledge production and management.
This project is relevant for museum and gallery studies, and any discipline where meaning is made and managed. Working to further academic understandings of collections and their information, this thesis also aims to encourage practical applications of these understandings in the development of more effective collections management policies and procedures for the future.
Food Marketing Costs Rose Modestly in 1993

description: Marketing costs are by far the largest chunk of food expenditures. Over three-fourths of what U.S. consumers spent for food in 1993 went to pay for marketing, and only 22 percent represented the farm value of food. While the cost of providing marketing services beyond the farm gate increased modestly in 1993 due to the slow pace of the economic recovery, it continues to be the most persistent source of rising food expenditures. Food expenditures are divided into two main components: the farm value and the marketing bill. The farm value is a measure of the payments farmers receive for their raw commodities used in food purchased by consumers at foodstores and eating places. The marketing bill represents the difference between the farm value of food produced on U.S. farms and the final cost to consumers. Such costs of processing agricultural commodities into food and bringing them from the farm to the dinner table include labor, packaging, transportation, and energy.

SALT revisits DY Cen: a rapidly-evolving strontium-rich single helium star

description: The hydrogen-deficient star DY Cen has been reported as an R CrB-type variable, an extreme helium star (with some hydrogen), and as a single-lined spectroscopic binary. It has been associated with a dramatic change in visual brightness and colour corresponding to a change in effective temperature ($T_{\mathrm eff}$) of some 20,000 K in the last century. To characterize the binary orbit and $T_{\mathrm eff}$ changes more precisely, new high-resolution spectroscopy has been obtained with SALT. The previous orbital period is not confirmed; previous measurements may have been confused by the presence of pulsations. Including data from earlier epochs (1987, 2002, and 2010), self-consistent spectral analyses from all four epochs demonstrate an increase in $T_{\mathrm eff}$ from 18,800 to 24,400 K between 1987 and 2015. Line profiles demonstrate that the surface rotation has increased by a factor two over the same interval. This is commensurate with the change in $T_{\mathrm eff}$ and an overall contraction. Rotation will exceed critical if contraction continues. The 1987 spectrum shows evidence of a very high abundance of the s-process element strontium. The very rapid evolution, non-negligible surface hydrogen and high surface strontium point to a history involving a very late thermal pulse. Observations over the next thirty years should look for a decreasing pulsation period, reactivation of R CrB-type activity as the star seeks to shed angular momentum and increasing illumination by emission lines from nebular material ejected in the past.

description: Norma Broude, professor emerita of art history, American University. To celebrate the closing day of its Degas/Cassatt exhibition, October 5, 2014, the National Gallery of Art hosted a public symposium titled Degas and Cassatt: Different Perspectives featuring conservators, curators, and scholars. On view beginning May 11, the exhibition focused on how the relationship between American Mary Cassatt (1844–1926) and Frenchman Edgar Degas (1834–1917) influenced their artistic practices and careers. Cassatt, who had settled in Paris in 1874, first met Degas in 1877. Over the next decade, the two artists engaged in an intense dialogue, turning to each other for advice and challenging each other to experiment with materials and techniques. Both made printmaking an important aspect of their careers and for a time collaborated on their endeavors. Their admiration and support for each other endured long after their art began to head in different directions: Degas continued to acquire Cassatt’s work, while she promoted his to collectors back in the United States. They remained devoted friends for 40 years, until Degas’s death.

Spin flip from dark to bright states in InP quantum dots

description: We report measurements of the time for spin flip from dark (non-light emitting) exciton states in quantum dots to bright (light emitting) exciton states in InP quantum dots. Dark excitons are created by two-photon excitation by an ultrafast laser. The time for spin flip between dark and bright states is found to be approximately 200 ps, independent of density and temperature below 70 K. This is much shorter than observed in other quantum dot systems. The rate of decay of the luminescence intensity, approximately 300 ps, is not simply equal to the radiative decay rate from the bright states, because the rate of decay is limited by the rate of conversion from dark excitons into bright excitons. The dependence of the luminescence decay time on the spin flip time is a general effect that applies to many experiments.
