description: In this paper, we analyze the holographic principle using loop quantum gravity (LQG). This will be done by using polymeric quantization for analysing the Yurtsever's holographic bound on the entropy, which is obtained from local quantum field theories. As the polymeric quantization is the characteristic feature of loop quantum gravity, we will argue that this calculation will indicate the effect of loop quantum gravity on the holographic principle. Thus, we will be able to explicitly demonstrate the violation of the holographic principle in the loop quantum gravity.

description: Report Introduction: Perhaps the most critical problem presented by the rapidly increasing world demand for cellulose pulps is the supply of softwoods. The long-fibered pulps produced from them are essential for the manufacture of wrapping and other high tear-resistance papers. With few exceptions, stands of the species are found only in the Northern Hemisphere and without considering Siberia the extent of softwood forests is known. In the United States, in Australia, and to a limited extent in Europe, there is an increasing production of cellulose pulps from certain hardwood species. Blends of soft wood and hardwood pulps to produce a variety of paper and board products are becoming standard practice in many mills. A study of tropical woods as a source of cellulose pulp is of extreme importance. This paper is designed to show how a partial, practical, and economic solution to the problem can be given on the basis of the chemical and physical characteristics of pulp fibers from agricultural residues. Examples of applied research will be described which point the way to success in this field

description: We report the discovery of the eighth and ninth known Trojans in stable orbits around Neptune's leading Lagrange point, L4. The objects 2014 QO$_{441}$ and 2014 QP$_{441}$ were detected in data obtained during the 2013-14 and 2014-15 observing seasons by the Dark Energy Survey, using the Dark Energy Camera (DECam) on the 4-meter Blanco telescope at Cerro Tololo Inter-American Observatory. Both are in high-inclination orbits (18.8$^{\circ}$ and 19.4$^{\circ}$ respectively). With an eccentricity of 0.104, 2014 QO$_{441}$ has the most eccentric orbit of the eleven known stable Neptune Trojans. Here we describe the search procedure and investigate the objects' long-term dynamical stability and physical properties.

description: This paper describes a prototype World Wide Web-accessible database of slide images developed for the University of North Carolina at Chapel Hill School of Journalism and Mass Communication Library, and a pilot study conducted with prospective users of the slide images. The purpose of the pilot study was to observe information-seeking behaviors and strategies with reference to image data, and to investigate the role of domain expertise in determining these behaviors and strategies. Five journalism faculty members and six journalism students completed retrieval tasks using the slide database. They then completed a questionnaire about their experiences. Results showed that keyword or full text searching is preferred over browsing for structured retrieval tasks, and that the students were more likely to use the thumbnail image to pare down a result set, while faculty were more likely to use the text descriptions for this purpose. Suggestions for further study are given.

description: Search for invisible final states produced at the Large Hadron Collider (LHC) by new physics scenarios are normally carried out resorting to a variety of probes emerging from the initial state, in the form of single-jet, -photon and -$Z$ boson signatures. These are particularly effective for models of Supersymmetry (SUSY) in presence of $R$-parity conservation, owing to the presence in their spectra of a stable neutralino as dark matter candidate. We assume here as theoretical framework Supersymmetric ($B-L$) extension of the Standard Model (BLSSM), wherein a mediator for invisible decays can be $Z'$ boson. The peculiarity of the signal is thus that the final state objects carry a very large (transverse) missing energy, since the $Z'$ is naturally massive and constrained by direct searches and electro-weak precision tests to be at least in TeV scale region. Under these circumstances the efficiency in accessing the invisible final state and rejecting the standard model background is very high. This somehow compensates the rather meagre production rates. Another special feature of this invisible BLSSM signal is its composition, which is often dominated by sneutrino decays (alongside the more traditional neutrino and neutralino modes). Sensitivity of the CERN machine to these two features can therefore help disentangling the BLSSM from more popular SUSY models. We assess in this analysis the scope of the LHC in establishing the aforementioned invisible signals through a sophisticated signal-to-background simulation carried out in presence of parton shower, hadronisation and detector effects. We find that significant sensitivity exists already after 300 fb$^{-1}$ during Run 2. We find that mono-jet events can be readily accessible at the LHC, so as to enable one to claim a prompt discovery, while mono-photon and -$Z$ signals can be used as diagnostic tools of the underlying scenario.

description: The purpose of this study was to critically examine the cultural authenticity of materials held by the elementary school library collections in three North Carolina counties. Specifically, I looked at Cumberland and Robeson Counties in the southeastern part of the state and Swain County in the western part of the state. These counties are home to some of the largest Native student populations in North Carolina; by searching the elementary school online catalogs for each county, using a list of titles that are recommended as being culturally authentic, as well as a list of titles that are problematic in terms of cultural authenticity, I looked at whether or not the collections contained a balance of materials, or if they tended towards holdings that perpetuate misrepresentation and stereotypes. Further analysis of the results enabled a discussion about the role of the school media specialist as an advocate for students, addressed the importance of cultural authenticity, and suggested strategies for working with collections that may not be particularly culturally authentic.

description: We study the bidimensional voter model on a square lattice with numerical simulations. We demonstrate that the evolution takes place in two distinct dynamic regimes; a first approach towards critical site percolation and a further approach towards full consensus. We calculate the time-dependence of the two growing lengths finding that they are both algebraic though with different exponents (apart from possible logarithmic corrections). We analyse the morphology and statistics of clusters of voters with the same opinion. We compare these results to the ones for curvature driven two-dimensional coarsening.

description: Starting from the “concept of disarticulation” (McRobbie), in this article I want to have a detailed look at social interactions between women with different class backgrounds in Lifestyle-TV. The “concept of disarticulation” refers to the undermining of feminist achievements of the last years. Postfeminism as a form of Antifeminism is regarded as a base of this concept. Focussing on the ATV-programme “In der Schuldenfalle” I want to show, from a feminist perspective, how precarious lifestyles are represented in mass media and how they (re)produce gendered class differences in these representations. In popular Lifestyle-TV programmes female experts with a middle and upper class background transmit knowledge about everyday life (education, beauty, body, debt, etc.) from their perspective to women from lower strata. This kind of knowledge is not being taught in school; it implies and promises social mobility. Looking at “In der Schuldenfalle”, I particularly concentrate on the interaction between the financial expert and the so called “victim” involved in a “debt trap” in the context of class and gender. Finally, I raise the question of possible social gender identifications implied in watching Lifestyle- TV and the circulation of its practice of degrading speech in social space.
title: Deontic Obligations in Justification Logic
Creators: name: Rohani, Atefeh
Publisher: name: Universität Bern
Year: 2023
Subjects: subject: 000 Computer science, knowledge & systems
subject: 510 Mathematics

description: This thesis consists of two main chapters which connect two areas of deontic logic and justification logic. Deontic logic is logic of normative concepts, where the deontic reading of modal operator for □A is as "A is obligatory". On the other hand, justification logics replace an explicit term with modal operator such that instead of □A, justification logics features formulas of the form t : A, read as "A is justified by reason t", or "A is obligatory for the reason t", in deontic context.
In the second chapter, we focus on the category of non-normal modal logics and provide an explicit version of two logics in this category, the weakest non-normal modal logic E and logic EM, which is an extension of logic E by adding rule of monotonicity.
The main motivation for this attempt is raised from the following arguments initiated in the area of deontic logic. First, we consider paradoxes raising from deontic interpretation of modal operator in normal modal logic, which leads us towards non-normal modal logics.
The second issue is hyperintensionality. Considering the fact that deontic modals are hyperintensional, i.e., they can distinguish between logically equivalent formulas, one can see that traditional modal logic cannot provide an appropriate formalization of deontic situations. Since justification terms are hyperintensional in nature, we introduce novel justification logics as hyperintensional analogues to non-normal modal logics. We establish soundness and completeness with respect to various models and we study the problem of realization.
In the third chapter, we focus on conditional obligations in deontic logic. We review standard deontic logic and the well known Chisholm's puzzle confronting this system. For this reason, we turn into dyadic deontic logic which is often argued to be better than standard deontic logic at representing conditional and contrary-to-duty obligations.

description: In recent work by Dani and Mainkar, a family of finite simple graphs was used to construct nilmanifolds admitting Anosov diffeomorphisms. Our main object of study is this particular set of graphs, which we call Anosov graphs. Moreover, Dani and Mainkar give a lower bound on the number of Anosov graphs in terms of the number of vertices and number of edges. In this work, we improve this lower bound in terms of vertices and edges, and we give lower and upper bounds solely in terms of the number of vertices.

title: High-precision laser spectroscopy of helium-like carbon 12C4+
Creators: name: Imgram, Phillip
Publisher: name: UNSPECIFIED
Year: 2023

description: The size of an atomic nucleus is a fundamental observable and defined by the distribution of the neutrons and protons composing the nucleus and the respective mean-square radii. The precise investigation of the nuclear size across the chart of nuclides delivers important benchmarks for nuclear structure theory and tests our fundamental knowledge of matter. In contrast to matter and neutron radii, the nuclear charge radius can be probed through the well-known electromagnetic interaction. Different techniques have been developed over time to measure nuclear charge radii such as elastic electron scattering or muonic atom spectroscopy. While these techniques are typically limited to stable nuclei, collinear laser spectroscopy and resonant ionization spectroscopy are used to determine nuclear charge radii of short-lived radioactive isotopes relative to a reference charge radius of a stable isotope. In some cases, this can limit the uncertainty of the obtained charge radii of radioactive nuclei to the uncertainty of the reference measurements from elastic electron scattering or muonic atom spectroscopy. To overcome this limit in light mass nuclei like 10, 11B, an all-optical approach for the charge radius determination purely from laser spectroscopy measurements and non-relativistic QED calculations was tested in this work with the well-known nucleus of 12C through laser excitation of helium-like 12C4+ from the metastable 1s2s 3S1 state with a lifetime of 21 ms to the 1s2p 3PJ states. The high-precision collinear laser spectroscopy was performed at the Collinear Apparatus for Laser Spectroscopy and Applied Science (COALA), situated at the Institute for Nuclear Physics at the Technical University Darmstadt. In order to produce the the highly charged C4+ ions, a new electron beam ion source including a Wien filter for charge/mass separation was installed and commissioned at COALA. Additionally, a new switchyard and beam diagnostics were designed, built and installed. The 1s2s 3S1 → 1s2p 3PJ rest-frame transition frequencies were determined with less than 2 MHz uncertainty through quasi-simultaneous collinear and anticollinear laser spectroscopy. These transition frequencies are in excellent agreement with state-of-the-art ab initio atomic structure calculations and an all-optical nuclear charge radius of 12C was extracted. Its accuracy is limited by theory, which must be improved by two orders of magnitude before the experimental uncertainty becomes significant again. At that point, the accuracy of the extracted charge radius would have already outperformed all previous measurements of this observable. Furthermore, the high precision of this work enabled the estimation of the next missing order in the atomic structure calculations and the transition frequencies from this work can be used together with ongoing measurements in 13C4+ for a conventional determination of the mean-square charge radius difference δ⟨r2⟩12,13 between 12C and 13C which has not been measured so far by laser spectroscopy.

description: Pompe disease is a lysosomal storage disorder with impaired glycogen degradation caused by a deficiency of the enzyme acid α-glucosidase (GAA). Children with the severe infantile form do not survive beyond the first year of life without treatment. Since 2006, enzyme replacement therapy (ERT) with Alglucosidase alfa (Myozyme) has been available, which is a recombinant human GAA (rhGAA). Myozyme therapy has prolonged the life span of affected patients, but many patients showed a continuing, albeit slower, disease progression. A new generation of rhGAA, Cipaglucosidase alfa (Amicus) has a higher content of mannose-6-phosphate residues, which are necessary for efficient cellular uptake and lysosomal targeting. Cipaglucosidase alfa is co-administered with an enzyme stabilizer, Miglustat, which also optimizes the pharmacological properties. In mouse models, the superiority of Cipaglucosidase alfa/Miglustat compared to the previous standard therapy could be determined. Here, we report the disease course of a patient with severe infantile M. Pompe, who showed serious progression even with high-dose standard of care ERT. Changing the therapy to Cipaglucosidase alfa/Miglustat improved respiratory failure, cardiomyopathy, and motor functions significantly. The patient could be weaned from respiratory support and oxygen supplementation. Cardiac function was normalized. Most impressively, the patient, who had lost nearly all motor skills, acquired head control, learned to speak, and could move his wheelchair by himself. Overall, the patient’s clinical situation has improved dramatically with the new ERT.

description: We present a new method to find voids in cosmological simulations based on the tidal and the velocity shear tensors definitions of the cosmic web. We use the fractional anisotropy (FA) computed from the eigenvalues of each web scheme as a void tracer. We identify voids using a watershed transform based on the local minima of the FA field without making any assumption on the shape or structure of the voids. We test the method on the Bolshoi simulation and report on the abundance and radial averaged profiles for the density, velocity and fractional anisotropy. We find that voids in the velocity shear web are smaller than voids in the tidal web, with a particular overabundance of very small voids in the inner region of filaments/sheets. We classify voids as subcompensated/overcompansated depending on the absence/presence of an overdense matter ridge in their density profile, finding that close to $65\%$ and $35\%$ of the total population are classified into each category, respectively. Finally, we find evidence for the existence of universal profiles from the radially averaged profiles for density, velocity and fractional anisotropy. This requires that the radial coordinate is normalized to the effective radius of each void. Put together, all these results show that the FA is a reliable tracer for voids, which can be used in complementarity to other existing methods and tracers.

description: This paper answers the modern movement of library design toward group spaces and computer workstations, sometimes to the cost of quiet spaces needed for contemplation. The study and observation of places created to inspire contemplation will yield a sampling of common characteristics that will be gathered into a rubric, and which can then be applied to today's theological libraries, helping them remain hospitable to the process of reflection. Not an argument against modern trends, this is a call for the defense of the quiet, the solitude, and the beauty that were once defining hallmarks of every library.

description: Identifying associations between interindividual variability in brain structure and behaviour requires large cohorts, multivariate methods, out-of-sample validation and, ideally, out-of-cohort replication. Moreover, the influence of nature vs nurture on brain-behaviour associations should be analysed. We analysed associations between brain structure (grey matter volume, cortical thickness, and surface area) and behaviour (spanning cognition, emotion, and alertness) using regularized canonical correlation analysis and a machine learning framework that tests the generalisability and stability of such associations. The replicability of brain-behaviour associations was assessed in two large, independent cohorts. The load of genetic factors on these associations was analysed with heritability and genetic correlation. We found one heritable and replicable latent dimension linking cognitive-control/executive-functions and positive affect to brain structural variability in areas typically associated with higher cognitive functions, and with areas typically associated with sensorimotor functions. These results revealed a major axis of interindividual behavioural variability linking to a whole-brain structural pattern.

description: One-dimensional Bose gas with contact interaction in optical lattices at zero temperature is investigated by means of the exact diffusion Monte Carlo algorithm. The results obtained from the fundamental continuous model are compared with those obtained from the lattice (discrete) Bose-Hubbard model, using exact diagonalization, and from the quantum sine-Gordon model. We map out the complete phase diagram of the continuous model and determine the regions of applicability of the Bose-Hubbard model. Various physical quantities characterizing the systems are calculated and it is demonstrated that the sine-Gordon model used for shallow lattices is inaccurate.

Controlled vocabulary

description: The Library of Congress Medium of Performance Thesaurus is a controlled vocabulary that will be used to describe music resources and is developed by the Music Library Association in conjunction with the Library of Congress. The objective of this study is to report on the current status of the LCMPT and to outline future steps which will allow the thesaurus to operate in a linked data environment. Four research questions examined the Simple Knowledge Organization System and its use with the LCMPT: the ways in which controlled vocabularies can be transformed into the Simple Knowledge Organization System format, the technologies and methods currently in use for this process, the effectiveness of these technologies and methods, and how the LCMPT can be most effectively converted into the Simple Knowledge Organization System format. Using existing documents, this qualitative study examined official World Wide Web Consortium documentation, the Open Metadata Registry, and was informed by work on the LCMPT performed at the Library of Congress. Tasks completed during an internship at the Library of Congress included discussion and planning for further LCMPT development and progress, development of the LCMPT Authority Data Elements, consideration of existing technologies and how they might be used in the development and deployment of LCMPT, conversion of existing LCMPT documentation into a more accessible format, research and documentation of the hierarchy of LCMPT, deployment of the LCMPT to a vocabulary space and element set space in the Open Metadata Registry, and consideration for future development of the LCMPT. The results of this study help to determine whether applying Semantic Web tools such as the Simple Knowledge Organization System to the LCMPT will allow music catalogers and other users of controlled vocabularies to begin harnessing the many potential benefits of the Semantic Web.

description: Calothrix cf. fusca Bornet & Flahault (1886: 364) Fig. 58 A–D.
Filaments solitary, or in small irregular groups, unbranched, up to 500 (–795) μm long, gradually tapering towards the ends. Sheath thin to thick, lamellated, often funnel-like widened, colourless to yellow-brown in colour. Trichomes continually narrowed towards the ends, 8.0–13.0 (–20.5) μm wide in the middle, usually constricted at the cross walls, ending in a fine, hair-like arrangement of hyaline cells. Vegetative cells at the base isodiametric or shorter than broad, 3.0–5.8 μm long × 6.0–10.5 μm wide, blue-green in colour; apical cells hyaline, 1.5–2 × longer than broad, 2.3–5.5 μm wide. Heterocytes basal, spherical to hemispherical 4.0–7.8 μm long × 5.5–8.5 μm wide. Akinetes not observed.
 Specimens observed:—Rainbow Beach Fens, Great Sandy Natl Park, Cooloola Section, Amity Swamp, North Stradbroke Is.
 Observations:—Growing in the metaphyton of acidic coastal wetlands amongst emergent sedges. C. fusca is considered cosmopolitan, more common in the northern temperate zone. Komárek (2013) considers material reported from various tropical and subtropical regions to be inconsistent with the original concept. Compare with C. furfosa Geitler from peaty pools in Indonesia.

description: The optical properties of LiFeAs with $T_c \simeq$ 18 K have been determined in the normal and superconducting states. The superposition of two Drude components yields a good description of the low-frequency optical response in the normal state. Below $T_c$, the optical conductivity reveals two isotropic superconducting gaps with $Δ_{1} \simeq 2.9$ $\pm$ 0.2 meV and $Δ_{2} \simeq 5.5$ $\pm$ 0.4 meV. A comparison between the superconducting-state Mattis-Bardeen and the normal-state Drude components, in combination with a spectral weight analysis, indicates that the spectral weight associated with a band which has a very small scattering rate is fully transferred to the superfluid weight upon the superconducting condensate. These observations provide clear evidence for the coexistence of clean- and dirty-limit superconductivity in LiFeAs.

description: This study reports on the professional development activities of music librarians throughout the United States. Telephone interviews were conducted with twenty-five music librarians in order to learn about the types of formal and informal activities they undertake to gain knowledge, develop their skills, and stay current. The findings indicate that many music librarians consider their involvement with the Music Library Association as their primary mode of formal professional development, while institutional activities are far less significant. The most valuable informal professional development activities are reading listservs and journals, communicating with colleagues, and pursuing research. Most have rather positive attitudes towards professional development and, whether pursuing these activities in order to provide better service to their users, to progress in their careers, or to contribute to the field, nearly all of the participants believe that professional development is a vital part of their job and enjoy engaging in it.

description: In this work we theoretically investigate a hybrid system of two optomechanically coupled resonators, which exhibits induced transparency. This is realized by coupling an optical ring resonator to a toroid. In the semiclassical analyses, the system displays bistabilities, isolated branches (isolas) and self-sustained oscillation dynamics. Furthermore, we find that the induced transparency transparency window sensitively relies on the mechanical motion. Based on this fact, we show that the described system can be used as a weak force detector and the optimal sensitivity can beat the standard quantum limit without using feedback control or squeezing under available experimental conditions.

Bridging the Gap: Handling Born-Digital Records in Manuscript Repositories

description: Due to the rapidly burgeoning volume of born-digital records, it behooves archives to
determine how they can best bridge the gap between handling analog and handling born-digital records. In addition to analyzing existing case studies of repositories that already accession and process electronic records, the study presented in this paper used both a survey instrument and semi-structured interviews with archivists to investigate whether and how manuscript repositories are handling born-digital materials. The intent of this study has been to pinpoint some of the problems that plague manuscript repositories in particular and to identify some practical steps that have already been taken at similar repositories and should be replicated and suggest courses for further study and action.  The problems of handling born-digital materials, especially when it comes to providing access, are not unique, and the profession would be well served by finding a space for collaboration to solve these thorny issues.
Long-lived states with well-defined spins in spin-$1/2$ homogeneous Bose gases

description: Many-body eigenfunctions of the total spin operator can be constructed from the spin and spatial wavefunctions with non-trivial permutation symmetries. Spin-dependent interactions can lead to relaxation of the spin eigenstates to the thermal equilibrium. A mechanism that stabilizes the many-body entangled states is proposed here. Surprisingly, in spite coupling with the chaotic motion of the spatial degrees of freedom, the spin relaxation can be suppressed by destructive quantum interference due to spherical vector and tensor terms of the spin-dependent interactions. Tuning the scattering lengths by the method of Feshbach resonances, readily available in cold atomic labs, can enhance the relaxation timescales by several orders of magnitude.

description: Using cosmological simulations, we address the properties of high-redshift star-forming galaxies (SFGs) across their main sequence (MS) in the plane of star-formation rate (SFR) versus stellar mass. We relate them to the evolution of galaxies through phases of gas compaction, depletion, possible replenishment, and eventual quenching. We find that the high-SFR galaxies in the upper envelope of the MS are compact, with high gas fractions and short depletion times ("blue nuggets"), while the lower-SFR galaxies in the lower envelope have lower central gas densities, lower gas fractions and longer depletion times, consistent with observed gradients across the MS. Stellar-structure gradients are negligible. The SFGs oscillate about the MS ridge on timescales $\sim0.4~t_{\mathrm{Hubble}}$ ($\sim1$ Gyr at $z\sim3$). The propagation upwards is due to gas compaction, triggered, e.g., by mergers, counter-rotating streams, and/or violent disc instabilities. The downturn at the upper envelope is due to central gas depletion by peak star formation and outflows while inflow from the shrunken gas disc is suppressed. An upturn at the lower envelope can occur once the extended disc has been replenished by fresh gas and a new compaction can be triggered, namely as long as the replenishment time is shorter than the depletion time. The mechanisms of gas compaction, depletion and replenishment confine the SFGs to the narrow ($\pm0.3$ dex) MS. Full quenching occurs in massive haloes ($M_{\mathrm{vir}}>10^{11.5}~M_\odot$) and/or at low redshifts ($z<3$), where the replenishment time is long compared to the depletion time, explaining the observed bending down of the MS at the massive end.

description: This study investigates curriculum support through a content analysis of the OPACs of three public library systems in North Carolina's Triangle region: Wake County Public Libraries, Durham County Libraries, and the Hyconeechee Regional Library System. The results of the analysis are used to determine the relative extent to which these systems support the curricular need of local students, where the concept of "curriculum support" is measured in terms of the number of titles and age of their publication. Results indicate that these library systems make an effort to support students' academic information needs, but that coverage of curricular subjects is often imbalanced and lacks a purposeful approach to collection development.
