p-adic Welch Bounds and p-adic Zauner Conjecture
Creators: name: K. Mahesh Krishna
Publisher: name: Zenodo
Year: 2022
Subjects: p-adic number field, p-adic Hilbert space, Welch bound, Zauner conjecture.

description: Let $p$ be a prime. For $d\in \mathbb{N}$, let $\mathbb{Q}_p^d$ be the standard $d$-dimensional p-adic Hilbert space. Let $m \in \mathbb{N}$ and $\text{Sym}^m(\mathbb{Q}_p^d)$ be the p-adic Hilbert space of symmetric m-tensors. We prove the following result. Let $\{\tau_j\}_{j=1}^n$ be a collection in $\mathbb{Q}_p^d$ satisfying (i) $\langle \tau_j, \tau_j\rangle =1$ for all $1\leq j \leq n$ and (ii) there exists $b \in \mathbb{Q}_p$ satisfying $ \sum_{j=1}^{n}\langle x, \tau_j\rangle \tau_j =bx$ for all $ x \in \mathbb{Q}^d_p.$ Then
 \begin{align}\label{WELCHNONABSTRACT}
 \max_{1\leq j,k \leq n, j \neq k}\{|n|, |\langle \tau_j, \tau_k\rangle|^{2m} \}\geq \frac{|n|^2}{\left|{d+m-1 \choose m}\right| }.
 \end{align}
 We call Inequality (\ref{WELCHNONABSTRACT}) as the p-adic version of Welch bounds obtained by Welch [\textit{IEEE Transactions on Information Theory, 1974}]. Inequality (\ref{WELCHNONABSTRACT}) differs from the non-Archimedean Welch bound obtained recently by M. Krishna as one can not derive one from another. We formulate p-adic Zauner conjecture.

Library Science--History

description: The Lanier Library Association in Tryon, North Carolina is one of the few remaining active membership libraries in the United States. At a time when many public libraries are facing drastic cuts in funding, and sometimes even facing closure, it has become important to examine how such an institution as the Lanier Library can exist, and what we can learn from this resilient organization that can be applied to public libraries today. Through an examination of the history of the Lanier Library, from its beginnings in 1889 to the present day, this study seeks to identify some of the factors that allow the library to remain viable. Also considered are issues associated with implementing the Lanier Library's user-pays model in a public library setting.
The almost product structure of Newton strata in the Deformation space of a Barsotti-Tate group with crystalline Tate tensors

description: In this paper, we construct the almost product structure of the minimal Newton stratum in deformation spaces of Barsotti-Tate groups with crystalline Tate tensors, similar to Oort's and Mantovan's construction for Shimura varieties of PEL-type. It allows us to describe the geometry of the Newton stratum in terms of the geometry of two simpler objects, the central leaf and the isogeny leaf. This yields the dimension and the closure relations of the Newton strata in the deformation space. In particular, their nonemptiness shows that a generalisation of Grothendieck's conjecture of deformations of Barsotti-Tate groups with given Newton polygon holds. As an application, we determine analogous geometric properties of the Newton stratification of Shimura varieties of Hodge type and prove the equidimensionality of Rapoport-Zink spaces of Hodge type.

description: AbstractCritical scholarship has already shown how automation processes may be problematic, for example, by reproducing social inequalities instead of removing them or requiring intense labour from education institutions’ staff instead of easing the workload. Despite these critiques, automated interventions in education are expanding fast and often with limited scrutiny of the technological and commercial specificities of such processes. We build on existing debates by asking: does automation of learning situations contribute to assetisation processes in EdTech, and if so, how? Drawing on document analysis and interviews with EdTech companies’ employees, we argue that automated interventions make assetisation possible. We trace their techno-commercial logic by analysing how learning situations are made tangible by constructing digital objects, and how they are automated through specific computational interventions. We identify three assetisation processes: First, the alienation of digital objects from students and staff deepens the companies’ control of digital services offering automated learning interventions. Second, engagement fetishism—i.e., treating engagement as both the goal and means of automated learning situations—valorises particular forms of automation. And finally, techno-deterministic beliefs drive investment and policy into identified forms of automation, making higher education and EdTech constituents act ‘as if’ the automation of learning is feasible.

description: Three-dimensional Polarized Light Imaging (3D-PLI) is a promising technique to reconstruct the nerve fiber architecture of human post-mortem brains from birefringence measurements of histological brain sections with micrometer resolution. To better understand how the reconstructed fiber orientations are related to the underlying fiber structure, numerical simulations are employed. Here, we present two complementary simulation approaches that reproduce the entire 3D-PLI analysis: First, we give a short review on a simulation approach that uses the Jones matrix calculus to model the birefringent myelin sheaths. Afterwards, we introduce a more sophisticated simulation tool: a 3D Maxwell solver based on a Finite-Difference Time-Domain algorithm that simulates the propagation of the electromagnetic light wave through the brain tissue. We demonstrate that the Maxwell solver is a valuable tool to better understand the interaction of polarized light with brain tissue and to enhance the accuracy of the fiber orientations extracted by 3D-PLI.

description: Broaching issues related to archives' ethical obligations to participants, transcripts as derivative documents, and web publication of archival materials, this case study explores the development of web access policies in oral history archives by examining the complications that emerged during the Archives of American Arts' (AAA) transcript review and web publication of a set of oral history interviews conducted in 2007-2008 with the Guerrilla Girls. Using program documentation and interview and questionnaire data from current and former Archives staff members as well as from a user of the Guerrilla Girls material, this study compares the AAA’s standard processes for oral history collection to the process of collecting the Guerrilla Girls interviews. Study participants discussed lessons learned from decisions made regarding web access to those interviews. Findings from this study bear a potentially transferrable relationship to policy review for oral history collections, archives’ donor/patron relations, and web access to oral histories.
A modified Friedberg-Lee symmetry for the TM1 neutrino mixing

Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this letter, we put forward a special neutrino mass matrix which is invariant under a modified Friedberg-Lee (FL) transformation $ν^{}_e \to ν^{}_e-2θ$ and $ν^{}_{μ, τ} \to ν^{}_{μ, τ}+θ$ with $θ$ being a space-time independent element of the Grassmann algebra. Compared to the original FL symmetry (with the transformation $ν^{}_{e, μ, τ} \to ν^{}_{e, μ, τ}+θ$) which results in the TM2 neutrino mixing, the modified FL symmetry will lead us to the TM1 mixing which has a better agreement with the experimental results. While the original FL symmetry has to be broken in order to produce a realistic neutrino mass spectrum, the modified FL symmetry is allowed to remain intact and give us a vanishing $m^{}_1$. A combination of the FL symmetry with the $μ$-$τ$ reflection symmetry is also discussed.

description: This study reports the results of questionnaire survey of young adult services for twenty-one  Eastern Iowa public libraries. Responding libraries were categorized as either in an  urbanized area, an urban cluster, or in a rural setting using 2000 Census data. Survey  responses were analyzed for an overall profile of young adult services and also for urban  and rural differences in availability of services for young adults. A follow-up unobtrusive  visit to fourteen of the libraries followed to develop a more complete picture of the  services available to young adults.  The overall performance of Eastern Iowa libraries was promising with two-thirds of the  libraries ranking "good," "very good," or "outstanding" for the number of overall  services for young adults provided. Results did not demonstrate large differences in  services provided between rural and urban libraries, but did show variability among  individual libraries. Library visits further confirmed variability between individual  libraries, not only in services provided but also in how those services were defined.

description: This study explores the extraction of lutein and zeaxanthin from Arthrospira Platensis (spirulina), with traditional protocols as a reference and response surface methodology as a tool for optimisation. An enhanced extraction procedure was developed for obtaining higher lutein concentration. The extraction process is further optimised using the central composite method, with the aid of design software tools. Methanol was used as the extracting solvent in a fixed ratio with dry spirulina powder. Saponification and hydrolysis using KOH, water and ethyl acetate/dichloromethane were done for isolating lutein and zeaxanthin from its ester. Ultraviolet–visible spectrophotometry was used for analysing the absorbance of the lutein sample at a wavelength of 445 nm. Using the Response Surface Methodology, trials of various combinations are run for finding optimum conditions of saponification. The major variables were reaction time, reaction temperature and concentration of KOH. Temperature range of 45–75°C, the reaction time of 45–70 min and KOH concentrations ranging from 2% to 10% are observed as the optimum range. The sample is filtered using a PVDF membrane and stored in acetone or isopropyl alcohol.
Finding optimal solutions for generalized quantum state discrimination problems

Year: 2015

description: We try to find an optimal quantum measurement for generalized quantum state discrimination problems, which include the problem of finding an optimal measurement maximizing the average correct probability with and without a fixed rate of inconclusive results and the problem of finding an optimal measurement in the Neyman-Pearson strategy. We propose an approach in which the optimal measurement is obtained by solving a modified version of the original problem. In particular, the modified problem can be reduced to one of finding a minimum error measurement for a certain state set, which is relatively easy to solve. We clarify the relationship between optimal solutions to the original and modified problems, with which one can obtain an optimal solution to the original problem in some cases. Moreover, as an example of application of our approach, we present an algorithm for numerically obtaining optimal solutions to generalized quantum state discrimination problems.

description: The goal of this paper is to present a historical literature review and analysis of archival reference literature in order to identify what, if any, assumptions the literature suggests that archivists hold, and have held in the past, about users. In order to determine implicit as well as explicit attitudes about users, attention has been focused on words used to refer to users as well as words used to describe users and their uses of archival materials. The paper focuses on North America archival literature from 1938 to 2009. This analysis is an attempt to raise awareness of assumptions archivists have or have had about users in order to facilitate assessment of reference policies and services.
Cycle representatives for the coarse-graining of systems driven into a non-equilibrium steady state

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: A major current challenge poses the systematic construction of coarse-grained models that are dynamically consistent, and, moreover, might be used for systems driven out of thermal equilibrium. Here we present a novel prescription that extends the Markov state modelling approach to driven systems. The first step is to construct a complex network of microstates from detailed atomistic simulations with transition rates that break detailed balance. The coarse-graining is then carried out in the cycle space of this network. To this end we introduce the concept of representatives, which stand for many cycles with similar properties. We show how to find these cycle communities using well-developed standard algorithms. Removing all cycles except for the representatives defines the coarse-grained model, which is mapped back onto a network with far fewer states and renormalized transition rates that, however, preserve the entropy production of the original network. Our approach is illustrated and validated for a single driven particle.

description: This paper begins with a concept: establishing a shared datasets initiative at the University of North Carolina at Chapel Hill's School of Information and Library Science (SILS). The initiative under proposal would attempt to introduce a collection of digital datasets, as a shared learning object, into courses across the school's curriculum to augment learning on digital data topics. The program would have four primary components: program oversight, infrastructure, resources, and services. This feasibility study was designed to ascertain how and whether a shared datasets initiative should be designed for the school. Interviews and focus groups were conducted with SILS faculty and students; in addition, several common reading program administrators and data experts were interviewed. Based on these data, specific recommendations are made for the implementation of a shared datasets initiative at SILS. These recommendations address decisions to be made about technology infrastructure, dataset selection, and the importance of visible success.

description: L'accès des PME au crédit reste très difficile en Algérie et dans le monde en entier, en raison de l'asymétrie d'information et de l'aléa moral qui caractérisent la relation entre les PME et les établissements de crédit. Cela conduit ces derniers à rationner les crédits accordés aux PME. Celles-ci, souvent familiales, dépendent essentiellement de l'endettement bancaire pour leur financement externe. Or, les banques sont fortement dépendantes de la qualité de la relation bancaire et des possibilités de garanties offertes par l'emprunteur. Les systèmes de garantie de crédit tels que la CGCI-PME en Algérie permettent de limiter les effets d'exclusion des PME qui ont du mal à accéder au financement externe. Cependant, la performance de ce type de mécanisme dépend de facteurs externes et internes liés à sa conception et à sa gestion. Dans le but de dégager des pistes d'amélioration pour les pratiques algériennes, nous avons mené une étude comparative entre le mécanisme CGCI-PME algérien et les pratiques dans les pays développés et en voie de développement. Nous avons observé des points de convergence, notamment en termes de structure légale et d'objectifs du système, et des divergences, en particulier en termes de critères d'éligibilité et de gestion des risques. Des pistes d'amélioration pourraient être la diversification de l'offre de garantie, la numérisation, le renforcement des capacités et le développement de mécanismes de gestion des risques.
Anisotropic Friedel oscillations in graphene-like materials: The Dirac point approximation in wave-number dependent quantities revisited

description: Friedel oscillations of the graphene-like materials are investigated theoretically beyond the Dirac point-approximation. Numerical calculations have been performed within the random phase approximation (RPA). For intra-valley transitions it was demonstrated that the contribution of the different Dirac points in the wave-number dependent quantities, such as dielectric function $ε(q)$, has been determined by the orientation of the wave-number with respect to the Dirac point position vector in $k$-space. Therefore identical contribution of the different Dirac points is not automatically guaranteed by the degeneracy of the Hamiltonian at these points. Meanwhile it was shown that the contribution of the inter-valley transitions is always anisotropic even when the Dirac points coincide with the Fermi level ($E_F=0$). This means that the Dirac point approximation based studies give the correct physics only at high wave length limit. The anisotropy of the static dielectric function reveals different contribution of the each Dirac point. Additionally, the anisotropic $k$-space dielectric function results in anisotropic Friedel oscillations in graphene-like materials. Calculations have also been performed in the presence of the Rashba interaction. It was shown that increasing the Rashba interaction strength slightly modifies the Friedel oscillations in graphene-like materials. Therefore the anisotropic dielectric function in $k$-space is the clear manifestation of band anisotropy in the graphene-like systems.

description: We consider the many-body spectra of interacting bosonic quantum fields on a lattice in the semiclassical limit of large particle number $N$. We show that the many-body density of states can be expressed as a coherent sum over oscillating long-wavelength contributions given by periodic, non-perturbative solutions of the, typically non-linear, wave equation of the classical (mean-field) limit. To this end we construct the semiclassical approximation for both the smooth and oscillatory part of the many-body density of states in terms of a trace formula starting from the exact path integral form of the propagator between many-body quadrature states. We therefore avoid the use of a complexified classical limit characteristic of the coherent state representation. While quantum effects like vacuum fluctuations and gauge invariance are exactly accounted for, our semiclassical approach captures quantum interference and therefore is valid well beyond the Ehrenfest time where naive quantum-classical correspondence breaks down. Remarkably, due to a special feature of harmonic systems with incommesurable frequencies, our formulas are generically valid also in the free-field case of non-interacting bosons.

description: This year, the Nara Institute of Science and Technology (NAIST)'s submission to the 2015 Workshop on Asian Translation was based on syntax-based statistical machine translation, with the addition of a reranking component using neural attentional machine translation models. Experiments re-confirmed results from previous work stating that neural MT reranking provides a large gain in objective evaluation measures such as BLEU, and also confirmed for the first time that these results also carry over to manual evaluation. We further perform a detailed analysis of reasons for this increase, finding that the main contributions of the neural models lie in improvement of the grammatical correctness of the output, as opposed to improvements in lexical choice of content words.

description: This study examined popular American action/adventure comic books from the year 2002, comparing the portrayal of men and women. Four categories of action/adventure comics were defined and the five best-selling titles in each category were identified. Six issues of each title were analyzed for textual and visual stereotyping. Women continue to be in the minority. As a result, women are less likely to be main characters, the rescuer or the person in charge. Women are also objectified visually by depicting them with large breasts, tiny waists, revealing outfits and uncomfortable poses.

description: We study role of site substitutions at In and Te site in In2Te5 on the thermoelectric behavior. Single crystals with compositions In2(Te1-xSex)5 (x = 0, 0.05, 0.10) and Fe0.05In1.95(Te0.90Se0.10)5 were prepared using modified Bridgman-Stockbarger technique. Electrical and thermal transport properties of these single crystals were measured in the temperature range 6 - 395 K. A substantial decrease in thermal conductivity is observed in Fe substituted samples attributed to the enhanced phonon point-defect scattering. Marked enhancement in Seebeck coefficient S along with a concomitant suppression of electrical resistivity \r{ho} is observed in Se substituted single crystals. An overall enhancement of thermoelectric figure of merit (zT) by a factor of 310 is observed in single crystals of Fe0.05In1.95(Te0.90Se0.10)5 compared to the parent In2Te5 single crystals.

description: We investigate the gauged Nambu-Jona-Lasinio model in curved spacetime at the large $N_c$ limit and in slow-roll approximation. The model can be described by the renormalization group corrected gauge-Higgs-Yukawa theory with the corresponding compositeness conditions. Evaluating the renormalization group (RG) improved effective action, we show that such model can produce CMB fluctuations and find inflationary parameters: spectral index, tensor-to-scalar-ratio and running of the spectral index. We demonstrate that the model can naturally satisfy the Planck 2015 data and maybe considered as an alternative candidate for Higgs inflation.

Information and development: strategies for disseminating development literature

description: Information is important to the development process. Not only does information expand the possibilities of project strategies, but it also facilitates participatory development and empowerment. Information is an asset and a resource for development professionals, sponsoring governments and agencies, and the target population. This paper considers the variety of distribution methods available for disseminating development literature. The premise of this paper is that given the infrastructure of the developing world and the costs associated with connectivity, the current trend of making information available via the Internet is less effective than an alternative strategy for disseminating development-related literature of using CD-ROMs or other storage devices in lieu of or in addition to putting documentation on the Internet.

Librarians in motion pictures

description: The stereotypical image of librarians in film is examined through a content analysis study of thirty-five librarian characters in twenty films spanning the years 1921 to 2004. Previous research into the stereotype of the librarian is reviewed, followed by an analysis of the physical, environmental, and social characteristics of the librarian characters. The results of the analysis show some evidence that the image of librarians in film has changed over time.

description: Let K/k be a finite Galois extension of number fields with Galois group G, S a large set of primes of K, and E the G-module of S-units of K. Previous work has determined the data which is necessary to determine the stable isomorphism class of E. This paper explains how to build a G-module M from this data which has the property that M is stably isomorphic to the direct sum of E and some free G-module F.

description: The growth of galaxies is a key problem in understanding the structure and evolution of the universe. Galaxies grow their stellar mass by a combination of star formation and mergers, with a relative importance that is redshift dependent. Theoretical models predict quantitatively different contributions from the two channels; measuring these from the data is a crucial constraint. Exploiting the UltraVISTA catalog and a unique sample of progenitors of local ultra massive galaxies selected with an abundance matching approach, we quantify the role of the two mechanisms from z=2 to 0. We also compare our results to two independent incarnations of semi-analytic models. At all redshifts, progenitors are found in a variety of environments, ranging from being isolated to having 5-10 companions with mass ratio at least 1:10 within a projected radius of 500 kpc. In models, progenitors have a systematically larger number of companions, entailing a larger mass growth for mergers than in observations, at all redshifts. Generally, in both observations and models, the inferred and the expected mass growth roughly agree, within the uncertainties. Overall, our analysis confirms the model predictions, showing how the growth history of massive galaxies is dominated by in situ star formation at z~2, both star-formation and mergers at 1

Reading like a nun: The composition of convent libraries in Renaissance Europe

description: This paper examines the composition of convent libraries in Renaissance Europe, specifically Italy and Spain. While much research on monastic libraries has occurred, none has concerned convent libraries. They are unique because they include writing by and for women. The author used previous historical research to form an overview of a convent library's composition. Examining monastic and Tridentine rules regarding literature collected and produced in convents allows one to understand if legislation restricted convent literature. From there, examining scribal work performed in convents, a few known convent holdings, and the works written by nuns themselves can illustrate other manuscripts and books in a convent library. These methods lead to the conclusion that convent libraries contained collections rich in social history and women's history because they contained some of the only literature by, for, and about women.
Test of the theoretical hyperfine structure of the molecular hydrogen ion at the 1-ppm level

description: We revisit the $m α^6 (m/M)$ order corrections to the hyperfine splitting in the H$_2^+$ ion, and find a hitherto unrecognized second-order relativistic contribution associated with the vibrational motion of the nuclei. Inclusion of this correction term produces theoretical predictions which are in excellent agreement with experimental data [K. B. Jefferts, Phys.\ Rev.\ Lett.\ \textbf{23}, 1476 (1969)], thereby concluding a nearly fifty years long theoretical quest to explain the experimental results within their 1-ppm error. The agreement between theory and experiment corroborates the proton structural properties as derived from the hyperfine structure of atomic hydrogen. Our work furthermore indicates that for future improvements, a full three-body evaluation of the $m α^6 (m/M)$ correction term will be mandatory.
