description: We consider nonlocal modification of the Einstein theory of gravity in framework of the pseudo-Riemannian geometry. The nonlocal term has the form $\mathcal{H}(R) \mathcal{F}(\Box)\mathcal {G}(R)$, where $\mathcal{H}$ and $\mathcal{G}$ are differentiable functions of the scalar curvature $R,$ and $ \mathcal{F}(\Box)= \displaystyle \sum_{n =0}^{\infty} f_{n}\Box^{n}$ is an analytic function of the d'Alambert operator $\Box .$ Using calculus of variations of the action functional, we derived the corresponding equations of motion. The variation of action is induced by variation of the gravitational field, which is the metric tensor $g_{μν}$. Cosmological solutions are found for the case when the Ricci scalar $R$ is constant.

description: We consider two entangled accelerating qubits coupled with real scalar fields, each described by the Unruh-Wald model. It is demonstrated that because of the Unruh effect, the bipartite entanglement of the two qubits suddenly dies when the acceleration of one or more qubits are large enough. We also consider three entangled accelerating qubits in GHZ state and in W state, with equal acceleration-frequency ratio, and found that in either state, the tripartite entanglement suddenly dies at a certain value of acceleration-frequency ratio. The equivalence between the Rindler metric and the Schwarzchild metric in the vicinity of the horizon of a black hole implies that for the two entangled qubits outside a black hole, the entanglement suddenly dies when one or both of the qubits are close enough to the horizon, while for the three entangled qubits in GHZ or W state, the tripartite entanglement suddenly dies when these qubits are close enough to the horizon.

description: Instrumental variables analysis using genetic markers as instruments is now a widely used technique in epidemiology and biostatistics. As single markers tend to explain only a small proportion of phenotypic variation, there is increasing interest in using multiple genetic markers to obtain more precise estimates of causal parameters. Structural mean models (SMMs) are semiparametric models that use instrumental variables to identify causal parameters. Recently, interest has started to focus on using these models with multiple instruments, particularly for multiplicative and logistic SMMs. In this paper we show how additive, multiplicative and logistic SMMs with multiple orthogonal binary instrumental variables can be estimated efficiently in models with no further (continuous) covariates, using the generalised method of moments (GMM) estimator. We discuss how the Hansen J-test can be used to test for model misspecification, and how standard GMM software routines can be used to fit SMMs. We further show that multiplicative SMMs, like the additive SMM, identify a weighted average of local causal effects if selection is monotonic. We use these methods to reanalyse a study of the relationship between adiposity and hypertension using SMMs with two genetic markers as instruments for adiposity. We find strong effects of adiposity on hypertension.

title: Conceptualising older horse care: a sociological exploration of the human-horse relationship
Creators: name: Smith, Rebecca
Publisher: name: University of Liverpool Repository
Year: 2028

description: Horses in the UK are increasingly being cared for into old age and the equine population as a whole is ageing. The inherent reliance on humans to provide for a horse’s needs means the human-horse relationship is key to determining how, and by which means, a horse’s needs are met as they age. Older horses frequently undergo changes in their lifestyle or management and are at increased risk of chronic disease, yet often receive reduced veterinary involvement in their care. This thesis sought to explore how horse owners and carers make decisions for their horse’s management and health care, and the role of vet-owner relationships in shaping management decisions. This study used multiple sources of qualitative data including; 12 open-access online discussion forum threads containing 326 comments, 13 sets of veterinary clinical records and semi-structured interviews with 25 owners of older horses, nine of their respective vets, four livery yard owners and one livery yard manager. Data were collected and analysed using a constructivist grounded theory approach in order to develop novel sociological theory about these human-horse relationships. Caring for an older horse involved an ongoing dynamic model of care. This study identified six contextual factors that shaped the nature of owners’ relationship with their horse, and as these factors dynamically interacted the relationship was reconstructed over time. Nurturing an ageing horse required daily monitoring of their responses, weighing up different facets of their lifestyle and adjusting management accordingly. Health care interventions were adopted depending on perceived need. Whether problems in the horse constituted the need for veterinary (vet) advice was dependent upon past experiences with older horses, independent research and the vet-owner relationship. Vets relied upon owners engaging with them and the way in which owners presented an issue of concern framed a consultation. Through an interplay between owner and vet, problems were identified and solutions negotiated. A vet’s perception of appropriate care was influenced by their assessment of a horse and their relationship with an owner; therefore, decision-making was not clear-cut. Owners’ relationships with their vet impacted on how they constructed the value of veterinary advice and on the way in which veterinary expertise was sought. Findings illustrate that the relationship between owner and horse is deeply rooted in the everyday contact and care that is performed over time. The steps an owner takes to consult a vet both reflects, and shapes, the vet-owner relationship. The current veterinary model of care and its ability to optimise older horse health is influenced by a multitude of structural and interactional factors. Findings suggest that older horse care may be improved through reflection on current practices, and strategies which accommodate, and capitalise on, owners’ dynamic experience of horse care.

description: A single enzyme found in both Drosophila and mammalian cells is able to selectively bind and degrade transforming growth factor (TGF)-alpha and insulin, but not EGF, at physiological concentrations. These growth factors are also able to inhibit binding and degradation of one another by the enzyme. Although there are significant immunological differences between the mammalian and Drosophila enzymes, the substrate specificity has been highly conserved. These results demonstrate the existence of a selective TGF-alpha-degrading enzyme in both Drosophila and mammalian cells. The evolutionary conservation of the ability to degrade both insulin and TGF-alpha suggests that this property is important for the physiological role of the enzyme and its potential for regulating growth factor levels.

Our method does not rely on any entropy inequality, and is substantially more accurate than the approaches proposed in previous works. We apply our theory to the single-band Hubbard model at different fillings, and show that our results compare quantitatively well with dynamical mean field theory in the metallic phase. We discuss potential applications of our technique within the framework of first principle calculations.

Transcriptional Pause Release Is a Rate-Limiting Step for Somatic Cell Reprogramming
Creators: name: BGI
Publisher: name: CNGB
Year: 2014

description: This SuperSeries is composed of the SubSeries listed below.Reactivation of the pluripotency network during somatic cell reprogramming by exogenous transcription factors involves chromatin remodeling and the recruitment of RNA polymerase II (Pol II) to target loci. Here, we report that Pol II is engaged at pluripotency promoters in reprogramming but remains paused and inefficiently released. We also show that bromodomain-containing protein 4 (BRD4) stimulates productive transcriptional elongation of pluripotency genes by dissociating the pause release factor P-TEFb from an inactive complex containing HEXIM1. Consequently, BRD4 overexpression enhances reprogramming efficiency and HEXIM1 suppresses it, whereas Brd4 and Hexim1 knockdown do the opposite. We further demonstrate that the reprogramming factor KLF4 helps recruit P-TEFb to pluripotency promoters. Our work thus provides a mechanism for explaining the reactivation of pluripotency genes in reprogramming and unveils an unanticipated role for KLF4 in transcriptional pause release.Overall design: Refer to individual Series

description: The utility of genome editing technologies for dis- ease modeling and developing cellular therapies has been extensively documented, but the impact of these technologies on mutational load at the whole-genome level remains unclear. We performed whole-genome sequencing to evaluate the muta- tional load at single-base resolution in individual gene-corrected human induced pluripotent stem cell (hiPSC) clones in three different disease models. In single-cell clones, gene correction by helper- dependent adenoviral vector (HDAdV) or Transcrip- tion Activator-Like Effector Nuclease (TALEN) exhibited few off-target effects and a low level of sequence variation, comparable to that accumulated in routine hiPSC culture. The sequence variants were randomly distributed and unique to individual clones. We also combined both technologies and developed a TALEN-HDAdV hybrid vector, which significantly increased gene-correction efficiency in hiPSCs. Therefore, with careful monitoring via whole-genome sequencing it is possible to apply genome editing to human pluripotent cells with minimal impact on genomic mutational load.

description: We have recently described the purification and characterization of an insulin-degrading enzyme (IDE) from Drosophila melanogaster that can cleave porcine insulin, is highly conserved through evolution and is developmentally regulated. We now report that the IDE is, in fact, an insulin EGF-binding protein (dp100) that we had isolated previously from Drosophila using an antihuman EGF receptor antiserum. This conclusion is based upon the following evidence. (a) dp100, identified by its ability to cross-link to labeled insulin, EGF, and transforming growth factor-alpha (TGF-alpha), and to be immunoprecipitated by anti-EGF receptor antisera, copurifies with the IDE activity. Thus, the purified IDE can be affinity labeled with either 125I-insulin, 125I-EGF, or 125I-TGF-alpha, and this labeling is specifically inhibited with unlabeled insulin, EGF, and the insulin B chain. (b) The antiserum to the human EGF receptor, which recognizes dp100, is able to specifically immunoprecipitate the insulin-degrading activity. (c) The purified IDE preparation contains a single protein of 110 kD which is recognized by both the anti-EGF receptor antiserum and anti-Drosophila IDE antiserum. (d) Polyclonal antiserum to the purified IDE, which specifically recognized only the 110-kD band in Drosophila Kc cells, immunoprecipitates dp100 cross-linked to 125I-TGF-alpha and dp100 cross-linked to 125I-insulin from the purified IDE preparation. (e) EGF, which competes with insulin for binding to dp100, also inhibits the degradation of insulin by the purified IDE. These results raise the possibility that a functional interaction between the insulin and EGF growth factor families can occur which is mediated by the insulin-degrading enzyme.

description: The precise mechanism by which insulin is degraded in mammalian cells is not presently known. Several lines of evidence suggest that degradation is initiated by a specific nonlysosomal insulin-degrading enzyme (IDE). The potential importance of this insulin protease is illustrated by the fact that there is an IDE in Drosophila melanogaster Kc cells that shares both physical and kinetic properties with its mammalian counterpart. We now demonstrate that the IDE is present in other Drosophila cell lines and in the embryo, the larvae, the pupae, and adult tissues of the fruit fly. Further, the level of the IDE is developmentally regulated, being barely detectable in the embryo but elevated ~5-fold in the larvae and pupae and ~10-fold in the adult fly. The IDE levels in the cell lines are particularly high, at least 10-fold greater than in the adult fly. Analysis of Schneider L3 cells indicates that the addition of the Drosophila hormone ecdysone, which induces differentiation of the cells, causes a small but reproducible increase in the level of the IDE and the insulin-degrading activity. These results demonstrate that the IDE is evolutionarily conserved and that its expression is tightly regulated during differentiation of Drosophila. The particular pattern of developmental regulation suggests that the IDE plays a specific and critical role in the later stages of the life cycle of the fly.

description: For a non-degenerate integral quadratic form $F(x_1, \dots , x_d)$ in $d\geq5$ variables, we prove an optimal strong approximation theorem. Let $Ω$ be a fixed compact subset of the affine quadric $F(x_1,\dots,x_d)=1$ over the real numbers. Take a small ball $B$ of radius $00$. Finally assume that an integral vector $(λ_1, \dots, λ_d) $ mod $m$ is given. Then we show that there exists an integral solution $X=(x_1,\dots,x_d)$ of $F(X)=N$ such that $x_i\equiv λ_i \text{ mod } m$ and $\frac{X}{\sqrt{N}}\in B$, provided that all the local conditions are satisfied. We also show that 4 is the best possible exponent. Moreover, for a non-degenerate integral quadratic form in 4 variables we prove the same result if $N$ is odd and $N\gg_{δ,Ω} (r^{-1}m)^{6+ε}$. Based on our numerical experiments on the diameter of LPS Ramanujan graphs and the expected square root cancellation in a particular sum that appears in Remark~\ref{evidence}, we conjecture that the theorem holds for any quadratic form in 4 variables with the optimal exponent $4$.

description: The identification of a novel protein from Drosophila melanogaster that binds both mammalian epidermal growth factor (EGF) and insulin has been reported (Thompson, K. L., S. J. Decker, and M. R. Rosner, 1985, Proc. Natl. Acad. Sci. USA., 82:8443-8447). This 100-kD protein (designated dp100) is also recognized by an antiserum against the human EGF receptor. To further characterize the properties of this protein, we have determined the binding spectrum, glycosylation state, and cellular distribution of dp100. Our results indicate that dp100 binds to other insulin-like and EGF-like growth factors with dissociation constants ranging from 10(-6) to 10(-9) M, and these ligands compete with each other for binding to dp100. All other ligands tested, including platelet-derived growth factor, transforming growth factor-beta, nerve growth factor, and glucagon, either did not bind or bound with a Kd greater than 10(-6) M. Unlike the Drosophila insulin receptor, dp100 does not bind to wheat germ agglutinin and is present in a cytoplasmic as well as a membrane-bound form that cannot be differentiated by two-dimensional PAGE. Further, dp100 is the sole transforming growth factor-alpha-binding protein detected by affinity labeling in Drosophila Kc cells. These results indicate that dp100 shares properties in common with, but distinct from, the Drosophila homologues of the insulin and EGF receptors.

description: The following study compares and contrasts the content of gift policy statements for R1 university libraries (as defined by the Carnegie Classification system) in the United States. The research provides a “snapshot” of current gift policy-writing practices by randomly sampling the gift policy statements from university library websites, coding the content of those statements, and analyzing the code for significant themes, commonalities, and divergences. In so doing, the research hopes to provide a much-needed point of reference for librarians and libraries looking to maximize the impact of gifted materials through the use of carefully written policies.

description: Metastable Ti–Nb alloys are promising bone-implant materials due to improved mechanical biofunctionality and biocompatibility. To overcome increasing bacterial infection risk, alloying with antibacterial elements is a promising strategy. This study investigates the effect of minor gallium (Ga) additions (4, 8 wt% Ga) to as-cast and solution-treated β-type Ti–45Nb-based alloy (96(Ti–45Nb)-4Ga, 92(Ti–45Nb)-8Ga (wt.%)) on corrosion and passive film properties, as well as cytocompatibility and antibacterial activity. The electrochemical properties were evaluated by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and Mott-Schottky analyses in phosphate-buffered saline (PBS). X-ray photoelectron spectroscopy (XPS) was performed to analyze the chemical composition of passive films. Early adhesion and viability of macrophages and Staphylococcus aureus were assessed by nucleocounting and colony-forming unit counting, respectively. The results showed that high corrosion resistance and passive film properties of Ti–45Nb are retained and even slightly improved with Ga. EIS results revealed that Ga addition improves the passive film resistance. XPS measurements of 92(Ti–45Nb)-8Ga show that the passive film contains Ti-, Nb- and Ga-based oxides, implying the formation of mixed (Ti–Nb-Ga) oxides. In addition, marginal Ga ion release rate was detected under free corrosion conditions. Therefore, it can be assumed that Ga species may contribute to passive film formation on Ga-containing alloys. The 92(Ti–45Nb)-8Ga elicited an antibacterial effect against S. aureus compared to cp-Ti at 4 h. Moreover, Ga-containing alloys showed good cytocompatibility with THP-1 macrophages at 24 h. In conclusion, it was demonstrated that Ga additions to Ti–45Nb are beneficial to corrosion resistance and showed promising initial host and bacterial interactions.

description: Fusion cross sections of 28Si + 28Si have been measured in a range above the barrier with a very small energy step (DeltaElab = 0.5 MeV). Regular oscillations have been observed, best evidenced in the first derivative of the energy-weighted excitation function. For the first time, quite different behaviors (the appearance of oscillations and the trend of sub-barrier cross sections) have been reproduced within the same theoretical frame, i.e., the coupled-channel model using the shallow M3Y+repulsion potential. The calculations suggest that channel couplings play an important role in the appearance of the oscillations, and that the simple relation between a peak in the derivative of the energy-weighted cross section and the height of a centrifugal barrier is lost, and so is the interpretation of the second derivative of the excitation function as a barrier distribution for this system, at energies above the Coulomb barrier.

description: This document is for an inter-tidal and underwater archaeological survey of the VAFB Boathouse embayment conducted April 28-29, 1978. This survey was undertaken to obtain additional cultural resources data for the Space and Missile Systems Organization (SAMSO) and to complete a Phase I archaeological survey and resource evaluation. No cultural resources were located within the project area, and additional underwater survey work is not recommended. Intertidal survey was a pedestrian survey conducted during low tides. Underwater survey was conducted by divers but low visibility and rough water conditions hampered efforts. Visibility for both efforts would have been quite poor.

“DAM Becky, Look at That Asset”: Digital Asset Management in Cultural Heritage Institutions
Creators: name: Crockett, Emily
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This study explores the role of the Digital Asset Management system within Cultural Heritage Institutions, and acts as a needs assessment for institutions with DAM systems in place. The study was conducted to understand how Digital Asset Management systems are being used in institutions and what the potential roadblocks are for implementation at smaller institutions.

Before delving into research, the paper outlines both the history of Digital Asset Management systems in museums, as well as its potential futures. The research is based on a survey and telephone interviews of industry professionals that occurred in the Spring of 2019. Despite a growing interest in DAM systems, Cultural Heritage Institutions are still in need of more nuanced features specific to their workflows.

description: Due to the novel properties of both 2D materials and rare-earth elements, developing 2D rare-earth nanomaterials has a growing interest in research. To produce the most efficient rare-earth nanosheets, it is essential to find out the correlation between chemical composition, atomic structure and luminescent properties of individual sheets. In this study, 2D nanosheets exfoliated from Pr3+-doped KCa2Nb3O10 particles with different Pr concentrations were investigated. Energy dispersive X-ray spectroscopy analysis indicates that the nanosheets contain Ca, Nb and O and a varying Pr content between 0.9 and 1.8 at%. K was completely removed after exfoliation. The crystal structure is monoclinic as in the bulk. The thinnest nanosheets are 3 nm corresponding to one triple perovskite-type layer with Nb on the B sites and Ca on the A sites, surrounded by charge compensating TBA+ molecules. Thicker nanosheets of 12 nm thickness (and above) were observed too by transmission electron microscopy with the same chemical composition. This indicates that several perovskite-type triple layers remain stacked similar to the bulk. Luminescent properties of individual 2D nanosheets were studied using a cathodoluminescence spectrometer revealing additional transitions in the visible region in comparison to the spectra of different bulk phases.
Lowering the Barrier of Entry: Developing an Online Self-Guided Learning Module for an Information Technology Competency Test
Creators: name: Cahoon, Claire
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Incoming master’s students in the University of North Carolina Chapel Hill School of Information and Library Science have the opportunity to take a three-part online test to complete their Information Technology Competency Requirement. While the test encourages students to teach themselves the skills, use outside resources, and continue to resubmit until they pass the exam, there are few updated resources available to assist with the process. This project created an online learning module that provides students with self-guided lessons and external resources in order to help them learn the skills necessary to pass the test. The overarching goal of the project was to lower the barrier of entry for incoming master’s students to teach themselves technology skills and improve their digital literacy.
Visualizing the evolution from the Mott insulator to a charge ordered insulator in lightly doped cuprates

description: A central question in the high temperature cuprate superconductors is the fate of the parent Mott insulator upon charge doping. Here we use scanning tunneling microscopy to investigate the local electronic structure of lightly doped cuprate in the antiferromagnetic insulating regime. We show that the doped charge induces a spectral weight transfer from the high energy Hubbard bands to the low energy in-gap states. With increasing doping, a V-shaped density of state suppression occurs at the Fermi level, which is accompanied by the emergence of checkerboard charge order. The new STM perspective revealed here is the cuprates first become a charge ordered insulator upon doping. Subsequently, with further doping, Fermi surface and high temperature superconductivity grow out of it.

description: Perovskite solar cells (PSCs) represent one of the most promising emerging photovoltaic technologies due to their high power conversion efficiency. However, despite the huge progress made not only in terms of the efficiency achieved, but also fundamental understanding of the relevant physics of the devices and issues which affect their efficiency and stability, there are still unresolved problems and obstacles on the path toward commercialization of this promising technology. In this roadmap, we aim to provide a concise and up to date summary of outstanding issues and challenges, and the progress made toward addressing these issues. While the format of this article is not meant to be a comprehensive review of the topic, it provides a collection of the viewpoints of the experts in the field, which covers a broad range of topics related to PSC commercialization, including those relevant for manufacturing (scaling up, different types of devices), operation and stability (various factors), and environmental issues (in particular the use of lead). We hope that the article will provide a useful resource for researchers in the field and that it will facilitate discussions and move forward toward addressing the outstanding challenges in this fast-developing field.
Magnetism in strongly interacting one-dimensional quantum mixtures

description: We consider two species of bosons in one dimension near the Tonks-Girardeau limit of infinite interactions. For the case of equal masses and equal intraspecies interactions, the system can be mapped to a S=1/2 XXZ Heisenberg spin chain, thus allowing one to access different magnetic phases. Using a powerful ansatz developed for the two-component Fermi system, we elucidate the evolution from few to many particles for the experimentally relevant case of an external harmonic confinement. In the few-body limit, we already find clear evidence of both ferromagnetic and antiferromagnetic spin correlations as the ratio of intraspecies and interspecies interactions is varied. Furthermore, we observe the rapid emergence of symmetry-broken magnetic ground states as the particle number is increased. We therefore demonstrate that systems containing only a few bosons are an ideal setting in which to realize the highly sought-after itinerant ferromagnetic phase.

Animal stories

description: This paper investigates the ways in which academic historians locate archival materials related to animals. Over the past twenty years, animals have become an increasingly popular subject for historians to research. However, these historians face challenges when searching in special collections or archives because of the authorship of their sources and current practices in archival description. In order to understand how these scholars search for these materials and their opinions on potential changes, the study consists of three semi-structured interviews with historians who work on animal-related histories. Knowledge of how niche researchers, such as animal-related historians, operate may benefit reference and technical services, helping archivists provide higher quality services to these patrons.
VAFB-1989-09: Power Control Line Surface Survey: Resynchronization of Substation K
Creators: name: Berry, Sarah H.
Year: 1989

description: This documents is a Section 106 report for the archaeological survey of a proposed power control line. The line is to allow resynchronization of standby and commercial power at the "K" substation (Building 676) from a remote power plant (Building 525). Three sections of the line will be buried by trenching. Prior to the surface survey, a records and literature search was conducted. No previously recorded archaeological sites lie within the APE, though CA-SBA-1940 runs adjacent to extant power poles that will be modified. The last section of the project has previously been surveyed. No sites are anticipated to be impacted by this project.
Parametrizing linear generalized Langevin dynamics from explicit molecular dynamics simulations

description: Fundamental understanding of complex dynamics in many-particle systems on the atomistic level is of utmost importance. Often the systems of interest are of macroscopic size but can be partitioned into few important degrees of freedom which are treated most accurately and others which constitute a thermal bath. Particular attention in this respect attracts the linear generalized Langevin equation (GLE), which can be rigorously derived by means of a linear projection (LP) technique. Within this framework a complicated interaction with the bath can be reduced to a single memory kernel. This memory kernel in turn is parametrized for a particular system studied, usually by means of time-domain methods based on explicit molecular dynamics data. Here we discuss that this task is most naturally achieved in frequency domain and develop a Fourier-based parametrization method that outperforms its time-domain analogues. Very surprisingly, the widely used rigid bond method turns out to be inappropriate in general. Importantly, we show that the rigid bond approach leads to a systematic underestimation of relaxation times, unless the system under study consists of a harmonic bath bi-linearly coupled to the relevant degrees of freedom.
