 Distribution in India: Odisha (Chilka Lake, also spelled Chilika Lake, Kalijai, Pathara and Satpara occurring probably throughout the year); Tamil Nadu (Pulicat lake).
 Notes: Following Silva et al. (1996) and Guiry & Guiry (2017), we consider the records of Polysiphonia angustissima Kützing in India as synonyms of P. subtilisissima. Desikachary et al. (1998), however, based on the number of pericentral cells (P. subtilissima with 4 ecorticate pericentral cells and P. angustissima with 10 to 20 pericentral cells) treated these two species separately. Ott (2009, p. 669) analyzed in detail several of the relatively less known, but truly freshwater, records of P. subtilissima in U.S.A. and in a freshwater stream in Jamaica, Central America. Lam et al. (2013) showed, based on DNA sequence analysis, that the freshwater and marine records of P. subtilisissima in North America and Europe are identical and are referable to the same species. Polysiphonia subtilissima is reported mostly from marine, estuarine lakes and mangrove habitats (see Guiry & Guiry 2017). Systematics of some species of Polysiphonia in Thanwein river mouth of Myanmar was studied by Jar-San & Soe-Htun (2015).

In Other Words: Writing Research as Ethico-onto-epistemic Practice
Creators: name: Sciannamblo, Mariacristina
Publisher: name: Tecnoscienza – Italian Journal of Science & Technology Studies
Year: 2020

description: This paper aims to uncover the agential character of writing research in the light of the concept of ethico-onto-epistemology. Theoretically, it unpacks the debate around reflexivity and the performativity of theories and methods, underlining the active role of writing research accounts that do not just “capture” the world, but rather enact multiple worlds. This argument is developed with the support of empirical accounts belonging to an ethnographic study in a telecommunication company, which are informed by conceptual sensibilities from STS and Feminist Science Studies intended as two related yet distinct theoretical frameworks. I conclude by arguing that taking up the call for ethico-onto-epistemology when writing research accounts call us to trouble the character of writing as a neutral practice, and to grapple with the power of accounting for – thus producing – multiple realities that differ in terms of epistemological, ethical and political relations.

Reflections on Self-tracking Routines: Conducting Maintenance of Digital Data
Creators: name: Yli-Kauhaluoma, Sari
Publisher: name: Tecnoscienza – Italian Journal of Science & Technology Studies
Year: 2020

description: Self-tracking technology is considered a critical learning and motivational resource that at best helps people self-reflect, thereby promoting attempts to make changes to lifestyle routines. This study examines how people incorporate this technology into their daily practices and the routines that self-tracking technology produces. The study is based on an indepth empirical analysis of a sample of interviews of volunteer participants of a pilot study aiming to promote health and wellness. The interviews took place in two phases: first, after three months of self-tracking (in total 27 interviewees) and second, at the end of the pilot study after ten months of self-tracking (in total 21 interviewees). The analysis focused on the participants’ reflections on their user experiences of a self-tracking device, the data that this produced and the resulting routines. The results suggest that people’s self-tracking routines are often related to the maintenance of a visible and continuous data flow in self-tracking applications. Routines for wearing, tending to and communicating with self-tracking devices play an important role. These routines are either only remotely related or not necessarily at all related to making changes to lifestyle routines that affect health and wellness. The development of routines through novel artefacts involve much invisible work and can even lead to unintended consequences. During self-tracking, the focus may remain on the technology alone and on attempts to develop routines for maintaining a continuous, accurate flow of data, rather than on actually making lifestyle changes.

description: For most catalogers, non-Roman script languages are more difficult to catalog than those in Roman scripts, and Arabic is particularly problematic. The cataloger must have a firm grasp of the language in order to correctly supply unwritten vowels and to use the standard Arabic-English dictionary which lists words by root rather than alphabetically. This manual presents the cataloger who does not have that language knowledge with strategies for effective copy cataloging searching. Topics include the development of Arabic cataloging automation, problems of name authority, distinguishing between Arabic and other languages written in the Arabic script, and using a non-alphabetic Arabic-to-English dictionary.

description: There is a growing need to develop effective techniques and tools for automatic metadata generation. The research presented in this master's paper compares the annotation functions of NCBO BioPortal with those of HIVE in order to determine whether basic term matching techniques or machine learning techniques produce higher quality results. The research was conducted by selecting a document set and testing it on both annotators. The metadata generated by the annotators was then assessed by three human evaluators in terms of relevance, precision, specificity, and exhaustivity. The research found that on average the results produced by the HIVE annotator, which employed machine learning techniques, had 10 percent higher specificity, 17 percent higher exhaustivity, and 19.4 percent higher precision than the results produced by BioPortal. The paper concludes that the machine learning underlying HIVE produces higher quality results than basic term matching techniques, and that this approach deserves greater research attention.

description: The objective of the present paper is to analyze the phase transition of asymptotically anti-de Sitter (AdS) black hole solutions in Lovelock gravity in the presence of nonlinear electrodynamics. First, we present the asymptotically AdS black hole solutions for two classes of the Born-Infeld type of nonlinear electrodynamics coupled with Einstein, Gauss-Bonnet and third order Lovelock gravity, separately. Then, in order to discuss the phase transition, we calculate both the heat capacity and the Ricci scalar of the thermodynamical line element. We present a comparison between the singular points of the Ricci scalar using Geometrothermodynamics method and the corresponding vanishing points of the heat capacity in the canonical ensemble. In addition, we discuss the effects of both Lovelock and nonlinear electrodynamics on the phase transition points.

Self-tracking Technologies and the Menstrual Cycle: Embodiment and Engagement with Lay and Expert Knowledge
Creators: name: Zampino, Letizia
Publisher: name: Tecnoscienza – Italian Journal of Science & Technology Studies
Year: 2020

description: The paper explores how humans intra-act with self-tracking technologies, reconfiguring the plurality of expert and lay knowledge. In particular, the current contribution presents an empirical analysis of the use of apps to manage menstrual periods. The article is positioned at the crossroad between three literatures: actor-network theory; new relational materialism; and a sociomaterial perspective on the medical field as relates to self-tracking practices. These approaches contribute to pay attention on the processes of embodiment and embodied knowing situated into sociomaterial practices. The aim is to explore how the body learns “to be affected” through the material entanglements between humans and apps, and how selftracking technologies are engaged and provide support for processes of embodied knowledge. Research findings draw attention to how interviewees intra-act with apps for menstrual tracking, along an imaginary continuum at whose opposite points we can find – on the one hand – minimal engagement with the knowledge inscribed in the app and – on the other – an affective engagement with the knowledge suggested by the app. This continuum shows the overlapping intra-actions that perform embodied knowledge about how women fertility, subordinate to the various historical stereotypes, works.

Archive-It

description: As web archives grow larger, institutions using Archive-It must keep track of a growing number of seeds and crawls. Managing this data often requires outside tools to create records of quality assurance efforts, scoping guidelines, and records for future colleagues and researchers to contextualize the archived websites. In an exploratory study of tracking systems for web archives, over twenty web archivists responded to a Qualtrics survey about their tracking practices as well as the reasons behind those practices. The survey revealed that only half the participants currently track seeds and crawls outside of Archive-It. Those who do track often rely upon spreadsheets, particularly for quality assurance and designing scoping guidelines. After reviewing the affordances of spreadsheets in light of participants’ stated priorities for tracking, the study suggests alternative practices for tracking seeds and crawls. This study is a crucial first step towards establishing best practices for documentation of web archives.
Training to Translate: Understanding and Informing Translational Animal Research in Pre-Clinical Pharmacology

description: We investigate translation in biomedicine by exploring how researchers supported by the British Pharmacological Society’s Integrative Pharmacology Fund (IPF) have responded to increasing translational aspirations within pre-clinical animal research. The IPF sought to enhance institutional capacities, collaborative practices, and personal skills within in vivo research in the quintessentially translational fields of pharmacology, physiology and toxicology. We identify three manifestations of the influence of translational aspirations: 1) shifting from the standardisation of animal models to the alignment of research on animals with human therapeutic pathways; 2) expanding relationalities of care in animal research from a focus on the animal body to institutional arrangements around clinical care; and 3) changing training around research ethics, integrity and good statistical practice. Concluding, we discuss the value of working interactively with those involved in the changing practices of animal research and translation as a means to foster reflexivity about what matters when “training to translate”.

Analytical mass formula and nuclear surface properties in the ETF approximation

description: The problem of the determination of the nuclear surface and surface symmetry energy is addressed in the framework of the Extended Thomas Fermi (ETF) approximation using Skyrme functionals. We propose an analytical model for the density profiles with variationally determined diffuseness parameters. For the case of symmetric nuclei, the resulting ETF functional can be exactly integrated, leading to an analytical formula expressing the surface energy as a function of the couplings of the energy functional. The importance of non-local terms is stressed, which cannot be simply deduced from the local part of the functional. In the case of asymmetric nuclei, we propose an approximate expression for the diffuseness and the surface energy. These quantities are analytically related to the parameters of the energy functional. In particular, the influence of the different equation of state parameters can be explicitly quantified. Detailed analyses of the different energy components (local/non-local, isoscalar/isovector, surface/curvature and higher order) are also performed. Our analytical solution of the ETF integral improves over previous models and leads to a precision better than 200 keV per nucleon in the determination of the nuclear binding energy for dripline nuclei.

description: Cookbooks do not have to function merely as objects in the kitchen space. They are versatile, primary resources that can provide researchers with a range of insight into social, economic, and cultural histories. Through the careful examination of the books, a researcher can parse an array of characteristics to produce a narrative about the people who created and used the cookbooks and the times in which they lived. This master’s paper describes such an analysis of thirty cookbooks published between 1872 and 1979 and housed in the University of North Carolina – Chapel Hill’s North Carolina Collection. Here we found that the cookbooks from the Piedmont region of North Carolina presented an assortment of information that tells of the types of foods that were being eaten over the course of a century according to availability and food ideologies, the transforming roles of men and women, and ultimately, the transforming cookbook.
Successively Thresholded Domain Boundary Roughening Driven by Pinning Centers and Missing Bonds: Hard-Spin Mean-Field Theory Applied to d=3 Ising Magnets

description: Hard-spin mean-field theory has recently been applied to Ising magnets, correctly yielding the absence and presence of an interface roughening transition respectively in $d=2$ and $d=3$ dimensions and producing the ordering-roughening phase diagram for isotropic and anisotropic systems. The approach has now been extended to the effects of quenched random pinning centers and missing bonds on the interface of isotropic and anisotropic Ising models in $d=3$. We find that these frozen impurities cause domain boundary roughening that exhibits consecutive thresholding transitions as a function interaction of anisotropy. For both missing-bond and pinning-center impurities, for moderately large values the anisotropy, the systems saturate to the "solid-on-solid" limit, exhibiting a single universal curve for the domain boundary width as a function of impurity concentration.

description: The random-cluster model, a correlated bond percolation model, unifies a range of important models of statistical mechanics in one description, including independent bond percolation, the Potts model and uniform spanning trees. By introducing a classification of edges based on their relevance to the connectivity we study the stability of clusters in this model. We derive several exact relations for general graphs that allow us to derive unambiguously the finite-size scaling behavior of the density of bridges and non-bridges. For percolation, we are also able to characterize the point for which clusters become maximally fragile and show that it is connected to the concept of the bridge load. Combining our exact treatment with further results from conformal field theory, we uncover a surprising behavior of the variance of the number of (non-)bridges, showing that these diverge in two dimensions below the value $4\cos^2{(π/\sqrt{3})}=0.2315891\cdots$ of the cluster coupling $q$. Finally, it is shown that a partial or complete pruning of bridges from clusters enables estimates of the backbone fractal dimension that are much less encumbered by finite-size corrections than more conventional approaches.

description: A questionnaire survey of biologists was conducted to gather data regarding how biologists access and use online bioinformatics resources for their genome related research.  The purpose of this study was to gain a better understanding of the information seeking behavior of biologists.  A total of 57 respondents from academia, industry and government voluntarily participated in this survey.  The survey indicated that the majority of biologists believe that online bioinformatics resources play very important roles for their research and show positive attitude toward future bioinformatics usage and training.  These respondents are active users and confident about themselves in using online bioinformatics resources.  Most have the basic skills to find information resources, and formulate queries.  The results also revealed the information challenges posed by online bioinformatics resources such as how to keep up to date on information resources, hot to query over multiple resources and various training needs for bioinformatics applications.

description: The possibility that dark matter may be in the form of a Bose-Einstein Condensate (BEC) has been extensively explored at galactic scale. In particular, good fits for the galactic rotations curves have been obtained, and upper limits for the dark matter particle mass and scattering length have been estimated. In the present paper we extend the investigation of the properties of the BEC dark matter to the galactic cluster scale, involving dark matter dominated astrophysical systems formed of thousands of galaxies each. By considering that one of the major components of a galactic cluster, the intra-cluster hot gas, is described by King's $β$-model, and that both intra-cluster gas and dark matter are in hydrostatic equilibrium, bound by the same total mass profile, we derive the mass and density profiles of the BEC dark matter. In our analysis we consider several theoretical models, corresponding to isothermal hot gas and zero temperature BEC dark matter, non-isothermal gas and zero temperature dark matter, and isothermal gas and finite temperature BEC, respectively. The properties of the finite temperature BEC dark matter cluster are investigated in detail numerically. We compare our theoretical results with the observational data of 106 galactic clusters. Using a least-squares fitting, as well as the observational results for the dark matter self-interaction cross section, we obtain some upper bounds for the mass and scattering length of the dark matter particle. Our results suggest that the mass of the dark matter particle is of the order of $μ$eV, while the scattering length has values in the range of $10^{-7}$ fm.

description: Numerous studies have reported that articles published in open access journals garner more citations than articles published in subscription-based journals, although this claim has recently come under intense scrutiny. What the debate about quantitative trends in citation patterns is missing is the opinion of the authors who publish articles in open access and subscription-based journals. In particular, are authors concerned with the anticipated post-publication metrics (citations, pageviews, or downloads) for their articles when choosing publication venues? For authors who have not submitted a manuscript to an open access journal, what percentage increase in post-publication metrics would be necessary to persuade them to do so? This study seeks to address these questions via semi-structured interviews with tenure-track faculty members in the Departments of Biology and Chemistry at the University of North Carolina at Chapel Hill. It is hoped that this study will help inform the outreach efforts of open access advocates and campus administrators.

description: Focusing light inside scattering media in a freely addressable fashion is challenging, as the wavefront of the scattered light is highly disordered. Recently developed ultrasound-guided wavefront shaping methods are addressing this challenge, albeit with relatively low modulation efficiency and resolution limitations. In this paper, we present a new technique, time-reversed ultrasound microbubble encoded (TRUME) optical focusing, which is able to focus light with improved efficiency and sub-ultrasound wavelength resolution. This method ultrasonically destructs microbubbles, and measures the wavefront change to compute and render a suitable time-reversed wavefront solution for focusing. We demonstrate that the TRUME technique can create an optical focus at the site of bubble destruction with a size of ~2 microns. Due to the nonlinear pressure-to-destruction response, the TRUME technique can break the addressable focus resolution barrier imposed by the ultrasound focus. We experimentally demonstrate a 2-fold addressable focus resolution improvement in a microbubble aggregate target.

description: Baeyer-Villiger monooxygenases (BVMOs) are attractive for selectively oxidizing various ketones using oxygen into valuable esters and lactones. However, the application of BVMOs is restrained by cofactor dependency and enzyme instability combined with water-related downsides such as low substrate loading, low oxygen capacity, and water-induced side reactions. Herein, we described a redox-neutral linear cascade with in-situ cofactor regeneration catalyzed by fused alcohol dehydrogenase and cyclohexanone monooxygenase in aqueous and microaqueous organic media. The cascade conditions have been optimized regarding substrate concentrations as well as the amounts of enzymes and cofactors with the Design of Experiments (DoE). The carrier-free immobilization technique, crosslinked enzyme aggregates (CLEAs), was applied to fusion enzymes. The resultant fusion CLEAs were proven to function in microaqueous organic systems, in which the enzyme ratios, water contents (0.5–5 vol. %), and stability have been systematically studied. The fusion CLEAs showed promising operational (up to 5 cycles) and storage stability.
Chang Sung-sheng: Literary Culture in Taiwan: Martial Law to Market Law
Creators: Lupke, Christopher
Publisher: name: University of Alberta Library
Year: 2008

This is a detailed review of Dr. Sung-sheng Yvonne Chang's book Literary Culture in Taiwan, a work that charts the path from literary developments in Taiwan under martial law to the post-martial law period when market forces began to prevail in the literary realm. Lupke emphasizes the theoretical sophistication of the book, highlighting how Chang turns to the work of Raymond Williams, Pierre Bourdieu, and Peter Uwe Hohendahl to build an argument for understanding literature from Taiwan within a social frame or field. In the book, she focuses not narrowly on the product of literature itself but on public intellectuals who sought to create a space for the publication of literature, including Zhang Daofan, Xia Ji'an (TA Hsia), Yu Tiancong, Wu Zhuoliu, Zhong Zhaozheng, Lin Haiyin, Gao Xinjiang, and Ya Xian.

description: In a previous work [1], we have argued that the algebra of non-abelian superselection rules is spontaneously broken to its maximal abelian subalgebra, that is, the algebra generated by its completing commuting set (the two Casimirs and a basis of its Cartan subalgebra). In this paper, alternative arguments confirming these results are presented. In addition, Lorentz invariance is shown to be broken in QCD, just as it is in QED. The experimental consequences of these results include fuzzy mass and spin shells of coloured particles like quarks, and decay life times which depend on the frame of observation [2-4]. In a paper under preparation, these results are extended to the ADM Poincaré group and the local Lorentz group of frames. The renormalisation of the ADM energy by infrared gravitons is also studied and estimated.

description: Strengthening participation of Global South researchers in tropical ecology and conservation is a target of our scientific community, but strategies for fostering increased engagement are mostly directed at Global North institutions and researchers. Whereas such approaches are crucial, there are unique challenges to addressing diversity, equity and inclusion (DEI) within the Global South given its socio-economic, cultural and scientific contexts. Sustainable solutions protecting biodiversity in the tropics depend on the leadership of Global South communities, and therefore DEI improvements in the Global South are paramount in our field. Here, we propose ten key actions towards equitable international collaborations in tropical ecology, which, led by Global South researchers, may improve DEI at institutional, national and international levels. At an institutional level, we recommend (1) becoming role models for DEI, (2) co-developing research with local stakeholders, and (3) promoting transparent funding management favouring local scientists. At a national level, we encourage (4) engagement in political actions protecting scientists and their research in tropical countries, (5) participation in improving biodiversity research policies, and (6) devising research that reaches society. At an international level, we encourage Global South researchers in international collaborations to (7) lead and direct funding applications, (8) ensure equitable workloads, and (9) procure equal benefits among national and foreign collaborators. Finally, (10) we propose that Global South leadership in DEI efforts has the most potential for worldwide improvements, supporting positive long-lasting changes in our entire scientific community.

description: Examining the literature of Chicago in the 20th Century both historically and critically, this bibliography attempts to find commonalities of voice in a list of selected works. The paper first looks at Chicago in a broader context, focusing particularly on perceptions of the city: both Chicago's image of itself and the world's of it. A series of criteria for inclusion in the bibliography are laid out, and with that a mention of several of the works that were considered but ultimately disqualified or excluded. Before looking into the Voice of the city, Chicago's history is succinctly summarized in a bibliography of general histories as well as of seminal and crucial events. The bibliography searching for Chicago's voice presents ten books chronologically, from 1894 to 2002, a close examination of those works does reveal themes and ideas integral to Chicago's identity.
Museum Migrations: An Analysis of Information Seeking Desires Toward Active Pursuits of Knowledge

description: Museums cannot merely present information to their patrons. In order for visitors to gain knowledge effectively, institutions must enable them to become actively involved in the learning process. In order to assist their visitors in seeking such knowledge, a museum must first recognize the types of information that appeal to them. This study explores the types of interests created by an exhibition, by questioning individuals visiting Sebastião Salgado's exhibition, "Migration: Humanity in Transition," at the Ackland Art Museum. Based on this data, the study proposes techniques, which may be further implemented to aid visitors in pursuing such interests. The study will also assist in bringing museums and libraries together, not only by providing visitors with a bibliography of related materials, but also by examining potential collaborative efforts.

description: Surface codes have emerged as promising candidates for quantum information processing. Building on the previous idea to realize the physical qubits of such systems in terms of Majorana bound states supported by topological semiconductor nanowires, we show that the basic code operations, namely projective stabilizer measurements and qubit manipulations, can be implemented by conventional tunnel conductance probes and charge pumping via single-electron transistors, respectively. The simplicity of the access scheme suggests that a functional code might be in close experimental reach.

Origin of the glass-like dynamics in molecular metals $\pmbκ$-(BEDT-TTF)$_{\textbf{2}}$X: implications from fluctuation spectroscopy and $\pmb{\textit{ab initio}}$ calculations

description: We have studied the low-frequency dynamics of the charge carriers in different organic charge-transfer salts $κ$-(BEDT-TTF)$_2$X with polymeric anions X by using resistance noise spectroscopy. Our aim is to investigate the structural, glass-like transition caused by the conformational degrees of freedom of the BEDT-TTF molecules' terminal ethylene groups. Although of fundamental importance for studies of the electronic ground-state properties, the phenomenology of the glassy dynamics is only scarcely investigated and its origin is not understood. Our systematic studies of fluctuation spectroscopy of various different compounds reveal a universal, pronounced maximum in the resistance noise power spectral density related to the glass transition. The energy scale of this precess can be identified with the activation energy of the glass-like ethylene endgroup structural dynamics as determined from thermodynamic and NMR measurements. For the first time for this class of 'plastic crystals', we report a typical glassy property of the relaxation time, namely a Vogel-Fulcher-Tammann law, and are able to determine the degree of fragility of the glassy system. Supporting $\textit{ab initio}$ calculations provide an explanation for the origin and phenomenology of the glassy dynamics in different systems in terms of a simple two-level model, where the relevant energy scales are determined by the coupling of the ethylene endgroups to the anions.
Crowd-based Information Organization: A Case Study of the Folk Ontologies in Wikipedia and TV Tropes

Information organization

description: Folk ontologies are the organically created, crowd-managed ontology-like structures used to organize information in wikis. This paper takes as case studies the folk ontologies of the wikis Wikipedia and TV Tropes, performing a three-part analysis on them. The first part describes the folk ontologies and examines how they are maintained and used. The second part creates an evaluation framework based on the ontology evaluation literature and considers the folk ontologies in that light. The third part takes a random sample of pages from the wiki and performs a quantitative analysis looking at where and how the folk ontologies appear and what effects their presence has. The goal of the paper is to advance our understanding of how people, in aggregate, organize information.
Canonical Hamiltonian for an extended test body in curved spacetime: To quadratic order in spin

description: We derive a Hamiltonian for an extended spinning test body in a curved background spacetime, to quadratic order in the spin, in terms of three-dimensional position, momentum, and spin variables having canonical Poisson brackets. This requires a careful analysis of how changes of the spin supplementary condition are related to shifts of the body's representative worldline and transformations of the body's multipole moments, and we employ bitensor calculus for a precise framing of this analysis. We apply the result to the case of the Kerr spacetime and thereby compute an explicit canonical Hamiltonian for the test-body limit of the spinning two-body problem in general relativity, valid for generic orbits and spin orientations, to quadratic order in the test spin. This fully relativistic Hamiltonian is then expanded in post-Newtonian orders and in powers of the Kerr spin parameter, allowing comparisons with the test-mass limits of available post-Newtonian results. Both the fully relativistic Hamiltonian and the results of its expansion can inform the construction of waveform models, especially effective-one-body models, for the analysis of gravitational waves from compact binaries.

description: International students are an expanding population at universities in the United States. It is important that academic librarians understand the information needs and unique challenges of this patron group and address their needs accordingly. This study explores international students' use of Davis Library at UNC-CH from the perspective of both academic librarians and international students. The study employed semi-structured interviews with three academic librarians at Davis Library and ten international students who have used Davis Library. The responses demonstrated areas in which the library is serving international students effectively and ineffectively, and it illustrated some of the challenges these patrons face in locating resources within the library.

description: We develop an intuitive model of 2D microwave near-fields in the unusual regime of centimeter waves localized to tens of microns. Close to an intensity minimum, a simple effective description emerges with five parameters which characterize the strength and spatial orientation of the zero and first order terms of the near-field, as well as the field polarization. Such a field configuration is realized in a microfabricated planar structure with an integrated microwave conductor operating near 1 GHz. We use a single 9Be+ ion as a high-resolution quantum sensor to measure the field distribution through energy shifts in its hyperfine structure. We find agreement with simulations at the sub-micron and few-degree level. Our findings give a clear and general picture of the basic properties of oscillatory 2D near-fields with applications in quantum information processing, neutral atom trapping and manipulation, chip-scale atomic clocks, and integrated microwave circuits.
