description: So far, flamelet theory has treated curvature as an independent parameter requiring specific means for closure. In this work, it is shown how the adoption of a two-dimensional orthogonal composition space allows obtaining formal mathematical relations between the flame curvatures and the gradients of the conditioning scalars (also called flamelet coordinates). With these, both curvatures become a flame response to the underlying flow, which conveniently allows removing them from the corresponding set of flamelet equations. While the demonstration is performed in the context of partially premixed flames, the approach is general and applicable to any orthogonal coordinate system.

Intellectual freedom--History

description: The Foreign Agents Registration Act (FARA) of 1938 was instrumental in detaining or destroying solicited and unsolicited mail from the Soviet Union bound for American addressees, including libraries and research centers, until the 1960s. FARA appears briefly in library literature, but no in-depth examination of its mechanisms and effects has been hazarded. This study posits a model for representing the importation and circulation of materials using Roger Friedland and Robert R. Alford's (1991) concept of institutional logics, highlighting the tension created through the competing interpretations of FARA of the Soviet export house, Department of Justice, Department of State, Post Office Department, Customs Bureau, booksellers, and research libraries. FARA's perniciousness coincided with the library's fundamental shift in institutional ethics, as the profession became politicized amid the coalescence of contemporary notions of intellectual freedom.
Large Opacity Variations in the High-Redshift Lyman-alpha Forest: the Signature of Relic Temperature Fluctuations from Patchy Reionization

description: Recent observations of the Lyman-alpha forest show large-scale spatial variations in the intergalactic Lyman-alpha opacity that grow rapidly with redshift at z>5, far in excess of expectations from empirically motivated models. Previous studies have attempted to explain this excess with spatial fluctuations in the ionizing background, but found that this required either extremely rare sources or problematically low values for the mean free path of ionizing photons. Here we report that much -- or potentially all -- of the observed excess likely arises from residual spatial variations in temperature that are an inevitable byproduct of a patchy and extended reionization process. The amplitude of opacity fluctuations generated in this way depends on the timing and duration of reionization. If the entire excess is due to temperature variations alone, the observed fluctuation amplitude favors a late-ending but extended reionization process that was roughly half complete by z~9 and that ended at z~6. In this scenario, the highest opacities occur in regions that reionized earliest, since they have had the most time to cool, while the lowest opacities occur in the warmer regions that reionized most recently. This correspondence potentially opens a new observational window into patchy reionization.

description: Cell-free networks are regarded as a promising technology to meet higher rate requirements for beyond fifth-generation (5G) communications. Most works on cell-free networks focus on either fully centralized beamforming to maximally enhance system performance, or fully distributed beamforming to avoid extensive channel state information (CSI) exchange among access points (APs). In order to achieve both network capacity improvement and CSI exchange reduction, we propose a partially distributed beamforming design algorithm for reconfigurable intelligent surface (RIS)-aided cell-free networks. We aim at maximizing the weighted sum-rate of all users by designing active and passive beamforming subject to transmit power constraints of APs and unit-modulus constraints of RIS elements. The weighted sum-rate maximization problem is first transformed into an equivalent weighted sum-mean-square-error (sum-MSE) minimization problem, and then alternating optimization (AO) approach is adopted to iteratively design active and passive beamformer. Specifically, active beamforming vectors are obtained by local APs and passive beamforming vector is optimized by central processing unit (CPU). Numerical results not only illustrate the proposed partially distributed algorithm achieves the remarkable performance improvement compared with conventional local beamforming methods, but also further show the considerable potential of deploying RIS in cell-free networks.

description: This paper characterizes the need for a theory that links context to information through the behaviors rooted in cultural identity and social awareness. Based on hypermedia objects and four methods of social communication, I develop a framework for a theory of social linking. This theory assumes that social interaction is the plinth from which we communicate and argues that studies in human computer interaction and information retrieval require ongoing exploration of social communication.

description: We examine the pair-instability origin of superluminous supernova 2018ibb. As the base model, we use a non-rotating stellar model with an initial mass of 250 Msun at about 1/15 solar metallicity. We consider three versions of the model as input for radiative transfer simulations done with the STELLA and ARTIS codes: with 25 Msun of 56Ni, 34 Msun of 56Ni, and a chemically mixed case with 34 Msun of 56Ni. We present light curves and spectra in comparison to the observed data of SN 2018ibb, and conclude that the pair-instability supernova model with 34 Msun of 56Ni explains broad-band light curves reasonably well between -100 and 250 days around the peak. Our synthetic spectra have many similarities with the observed spectra. The luminosity excess in the light curves and the blue-flux excess in the spectra can be explained by an additional energy source, which may be interaction of the SN ejecta with circumstellar matter. We discuss possible mechanisms of the origin of the circumstellar matter being ejected in the decades before the pair-instability explosion.

description: Mentoring in its formal and informal state is a common practice in many facets of human relationships.  As mentoring gains acceptance in both the education and business worlds, it is important to begin formalizing the process by which mentors and proteges are matched.  How can matching of mentors and proteges be done in the future to produce the most effective relationships possible?  Previous mentoring programs have used a number of different factors to match mentors with proteges.  Among these are several key factors, such as race, personality and attachment theory, which have been examined more closely.  Data that was collected for the E-Mentoring program developed at the University of North Carolina at Chapel Hill is the basis for suggestions for matching mentors and proteges.  Useful information such as their expectations of the program and their relationships were obtained from the interview data; however, due to logistical and transcriptions problems, open-ended surveys might be a better approach to gathering this data.  Due to the importance of this issue, there is hope it will continue to be researched further in the future.

Year: 2022
Subjects: subject: Machine Learning (cs.LG)

description: It is well known that tensor network regression models operate on an exponentially large feature space, but questions remain as to how effectively they are able to utilize this space. Using a polynomial featurization, we propose the interaction decomposition as a tool that can assess the relative importance of different regressors as a function of their polynomial degree. We apply this decomposition to tensor ring and tree tensor network models trained on the MNIST and Fashion MNIST datasets, and find that up to 75% of interaction degrees are contributing meaningfully to these models. We also introduce a new type of tensor network model that is explicitly trained on only a small subset of interaction degrees, and find that these models are able to match or even outperform the full models using only a fraction of the exponential feature space. This suggests that standard tensor network models utilize their polynomial regressors in an inefficient manner, with the lower degree terms being vastly under-utilized.

description: We study an ${\cal N} = 2$ supersymmetric generalization of the three-dimensional critical $O(N)$ vector model that is described by $N+1$ chiral superfields with superpotential $W = g_1 X \sum_i Z_i^2 + g_2 X^3$. By combining the tools of the conformal bootstrap with results obtained through supersymmetric localization, we argue that this model exhibits a symmetry enhancement at the infrared superconformal fixed point due to $g_2$ flowing to zero. This example is special in that the existence of an infrared fixed point with $g_1,g_2\neq 0$, which does not exhibit symmetry enhancement, does not generally lead to any obvious unitarity violations or other inconsistencies. We do show, however, that the $F$-theorem excludes the models with $g_1,g_2\neq 0$ for $N>5$. The conformal bootstrap provides a stronger constraint and excludes such models for $N>2$. We provide evidence that the $g_2=0$ models, which have the enhanced $O(N)\times U(1)$ symmetry, come close to saturating the bootstrap bounds. We extend our analysis to fractional dimensions where we can motivate the nonexistence of the $g_1,g_2\neq 0$ models by studying them perturbatively in the $4-ε$ expansion.

description: In the quest to build generative surrogate models as computationally efficient alternatives to rule-based simulations, the quality of the generated samples remains a crucial frontier. So far, normalizing flows have been among the models with the best fidelity. However, as the latent space in such models is required to have the same dimensionality as the data space, scaling up normalizing flows to high dimensional datasets is not straightforward. The prior L2LFlows approach successfully used a series of separate normalizing flows and sequence of conditioning steps to circumvent this problem. In this work, we extend L2LFlows to simulate showers with a 9-times larger profile in the lateral direction. To achieve this, we introduce convolutional layers and U-Net-type connections, move from masked autoregressive flows to coupling layers, and demonstrate the successful modelling of showers in the ILD Electromagnetic Calorimeter as well as Dataset 3 from the public CaloChallenge dataset.

Proper preservation of these digital items requires archivists to add several new  steps to their processing workflow. This paper discusses the steps developed to remove  digital files from the media on which they are housed in the Southern Historical  Collection of the University of North Carolina at Chapel Hill's Wilson Library. The  paper is divided into three major sections. The first section examines literature related to  digital archaeology, computer forensics and digital preservation. The second section  describes the Southern Historical Collection, its technological environment and the  process of developing a workflow. The paper concludes with a discussion of lessons  learned from the project, unresolved issues and potential solutions.

description: Beta-delayed proton emission from $^{21}$Mg has been measured at ISOLDE, CERN, with a detection setup including particle identification capabilities. $β$-delayed protons with center of mass energies between 0.39$\,$MeV and 7.2$\,$MeV were measured and used to determine the half life of $^{21}$Mg as $118.6\pm 0.5\,$ms. From a line shape fit of the $βp$ branches we extract spectroscopic information about the resonances of $^{21}$Na. Finally an improved interpretation of the decay scheme in accordance with the results obtained in reaction studies is presented.
Semiclassical Dynamics in Wigner Phase Space I : Adiabatic Hybrid Wigner Dynamics

description: The Wigner phase space formulation of quantum mechanics is a complete framework for quantum dynamic calculations that elegantly highlights connections with classical dynamics. In this series of two articles, building upon previous efforts, we derive the full hierarchy of approximate semiclassical (SC) dynamic methods for adiabatic and non-adiabatic problems in Wigner phase space. In paper I, focusing on adiabatic single surface processes, we derive the well-known Double Herman-Kluk (DHK) approximation for real-time correlation functions in Wigner phase space, and connect it to the Linearized SC (LSC) approximation through a stationary phase approximation. We exploit this relationship to introduce a new hybrid SC method, termed Adiabatic Hybrid Wigner Dynamics (AHWD) that allows for a few important `system' degrees of freedom (dofs) to be treated at the DHK level, while treating the rest of the dofs (the `bath') at the LSC level. AHWD is shown to accurately capture quantum interference effects in models of coupled oscillators, and the decoherence of vibrational probability density of a model I$_2$ Morse oscillator coupled to an Ohmic thermal bath. We show that AHWD significantly mitigates the sign-problem and employs a reduced dimensional prefactor bringing calculations of complex system-bath problems within the reach of SC methods. Paper II focuses on extending this hybrid SC dynamics to nonadiabatic processes.

description: In this work we investigate Majorana correlations in quantum impurities coupled to a topological superconducting wire. By employing a density matrix renormalization group approach, we have calculated the Majorana correlation functions in the ground state of the system for different positions of the impurities along the wire. We observe that the correlations decreases exponentially with the distance between the impurities and the ends of the wire. Moreover, different electron-electron interactions on the wire and on the impurities were also analyzed, and the results showed a stronger effect as the electron occupation in the wire is increased. Moreover, changing the occupation of the impurities by tuning their energy levels, we observe that for specific values of $ε$ the absolute value of correlation is highly peaked when the chemical potential lies within the window of the topological regime. These peaks are associated to coulomb blockade phenomena in the impurities, revealing very clearly its effect on the Majorana bound states in the topological phase of the system.

description: We present an approximate semiclassical (SC) framework for mixed quantized dynamics in Wigner phase space in a two-part series. In the first article, we introduced the Adiabatic Hybrid Wigner Dynamics (AHWD) method that allows for a few important `system' degrees of freedom to be quantized using high-level Double Herman-Kluk SC theory while describing the rest (the `bath') using classical-limit Linearized SC theory. In this second article, we extend our hybrid Wigner dynamics to nonadiabatic processes. The resulting Nonadiabatic Hybrid Wigner Dynamics (NHWD) has two variants that differ in the choice of degrees of freedom to be quantized. Specifically, we introduce NHWD(E) where only the electronic state variables are quantized and the NHWD(V) where both electronic state variables and a handful of strongly coupled nuclear modes are quantized. We show that while NHWD(E) proves accurate for a wide range of scattering models and spin-boson models, systems where a few nuclear modes are strongly coupled to electronic states require NHWD(V) to accurately capture the long-time dynamics. Taken together, we show that AHWD and NHWD represent a new framework for SC simulations of high-dimensional systems with significant quantum effects.

description: We provide a detailed exposition of our computational framework designed for the accurate calculation of real-frequency dynamical correlation functions of the single-impurity Anderson model (AM) in the regime of weak to intermediate coupling. Using quantum field theory within the Keldysh formalism to directly access the self-energy and dynamical susceptibilities in real frequencies, as detailed in our recent publication (https://doi.org/10.1103/PhysRevB.109.115128), the primary computational challenge is the full three-dimensional real-frequency dependence of the four-point vertex. Our codebase provides a fully MPI+OpenMP parallelized implementation of the functional renormalization group (fRG) and the self-consistent parquet equations within the parquet approximation. It leverages vectorization to handle the additional complexity imposed by the Keldysh formalism, using optimized data structures and highly performant integration routines. Going beyond the results shown in the previous publication, the code includes functionality to perform fRG calculations in the multiloop framework, at arbitrary loop order, including self-consistent self-energy iterations. Moreover, implementations of various regulators, such as hybridization, interaction, frequency, and temperature are supplied.

description: This paper describes a study conducted to examine copyright knowledge among special librarians in the United States to determine factors that may promote an increased knowledge of copyright and how it operates in a particular setting. A review of the literature indicates that awareness of copyright is high, but actual knowledge of copyright is lacking. Little research has been done specifically on the special librarian population, but the literature suggests the importance of the librarian as a facilitator of copyright compliance, and demonstrates a need for copyright education. This study used an online survey to solicit the opinions of special librarians on the issue, garnering 122 usable responses. Results indicate that more than half of the librarians surveyed were not comfortable with their copyright knowledge and showed a positive correlation between comfort and training. Results may be of interest to copyright educators, library managers, librarians, and those assessing MLS curricula.

description: We present a novel method for solving population density equations (PDEs), where the populations can be subject to non-Markov noise for arbitrary distributions of jump sizes. The method combines recent developments in two different disciplines that traditionally have had limited interaction: computational neuroscience and the theory of random networks. The method uses a geometric binning scheme, based on the method of characteristics, to capture the deterministic neurodynamics of the population, separating the deterministic and stochastic process cleanly. We can independently vary the choice of the deterministic model and the model for the stochastic process, leading to a highly modular numerical solution strategy. We demonstrate this by replacing the Master equation implicit in many formulations of the PDE formalism, by a generalization called the generalized Montroll-Weiss equation - a recent result from random network theory - describing a random walker subject to transitions realized by a non-Markovian process. We demonstrate the method for leaky- (LIF) and quadratic-integrate and fire (QIF) neurons subject to spike trains with Poisson and gamma distributed spike intervals. We are able to model jump responses for both models accurately to both excitatory and inhibitory input under the assumption that all inputs are generated by one renewal process.
Volume density maps of the 862nm DIB carrier and interstellar dust: a hint for the role of carbon-rich ejecta from AGB stars?

description: The carbonaceous macromolecules imprinting in astronomical spectra the numerous absorptions called Diffuse Interstellar Bands (DIBs) are omnipresent in the Galaxy and beyond and represent a considerable reservoir of organic matter. However, their chemical formulae, formation and destruction sites remain open questions. Their spatial distribution and the local relation to other interstellar species is paramount to unravel their role in the lifecycle of organic matter. Volume density maps bring local instead of line-of-sight distributed information, and allow for new diagnostics. We present the first large-scale volume (3D) density map of a DIB carrier and compare it with an equivalent map of interstellar dust. The DIB carrier map is obtained through hierarchical inversion of about 202,000 measurements of the 8621 nm DIB obtained with the Gaia-RVS instrument. It covers about 4000 pc around the Sun in the Galactic plane. A dedicated interstellar dust map is built based on extinction towards the same target stars. At the 50 pc resolution of the maps, the 3D DIB distribution is found remarkably similar in shape to the 3D distribution of dust. On the other hand, the DIB-to-dust local density ratio increases in low-dust areas. It is also increasing away from the disk, however, the minimum ratio is found to be shifted above the Plane to Z = +50pc. Finally, the average ratio is also surprisingly found to increase away from the Galactic Center. We suggest that the three latter trends may be indications of a dominant contribution of material from the carbon-rich category of dying giant stars to the formation of the carriers. Our suggestion is based on recent catalogues of AGB stars and estimates of their mass fluxes of C-rich and O-rich ejecta.

description: Pour les urbanistes, le phénomène de régionalisarion de l'urbain a des impacts bien au delà de I'organisation et de la planification du territoire. Transports, environnement, santé ... ; tous les champs de practiques de l'urbanisme sont affectés. La problématique du logement social au Québec montre bien la difficulté de trouver un cadre approprié et équitable à I'échelle régionale: les municipalités qui acceptent des logements sociaux sur leur territoire doivent contribuer au financement, alors que les municipalités plus fortunés n'ont pas un sous à débourser. Dans ce contexte, plusieurs s'inquiètent d'un transfert de responsabilités accrues vers les municipalités.
description: For planners, urban regionalization has impacts that go beyond the scope of land use planning. Many fields of planning practice are affected, including transportation, the environment, and health. The social housing issue in Québec illustrates the difficulty of finding an appropriate and equitable framework at the regional level. Municipalities that accept social housing within their boundaries must contribute to the funding, so wealthier municipalities are not spending anything. In this context, many are concerned about the increased devolution of responsibilities to the municipalities.

description: Dielectric metasurfaces with spatially varying birefringence and high transmission efficiency can exhibit exceptional abilities for controlling the photonic spin states. We present here some of our works on spin photonics and spin-photonic devices with metasurfaces. We develop a hybrid-order Poincare sphere to describe the evolution of spin states of wave propagation in the metasurface. Both the Berry curvature and the Pancharatnam-Berry phase on the hybrid-order Poincare sphere are demonstrated to be proportional to the variation of total angular momentum. Based on the spin-dependent property of Pancharatnam-Berry phase, we find that the photonic spin Hall effect can be observed when breaking the rotational symmetry of metasurfaces. Moreover, we show that the dielectric metasurfaces can provide great flexibility in the design of novel spin-photonic devices such as spin filter and spin-dependent beam splitter.

description: In anticipation of the upcoming 1999 CIP/OUQ Conference, this article attempts to explain some of the key emerging planning issues affecting Latin America. For the first time in CIP's 80-year history, this Conference will have a Latin American component as part of the program, in view of the increasing interest developed in Canada with the signing of trade agreements with Mexico and Chile. From a planner's point of view, there are at least two reasons why we should take an interest in Latin America: to capitalize on the Latin American experience in handling rapid growth with minimal resources; and to take advantage of an emerging market requiring professional services. By using specific Latin American examples, three main issues are discussed: the decentralization of government functions; the role of the private sector in the delivery of public services; and the increasing participation of NGOs in the planning, decisionmaking process. Finally, key areas are identified where Canadian planning expertise can be offered.
description: En prévision du prochain congrès de l'ICU/OUQ, cet article décrit certaines des nouvelles problématiques de l'urbanisme en Amérique latine. Pour la première fois dans les 80 ans d'histoire de l'ICU, le programme de notre congrès aura une composante latino-américaine, compte tenu de l'intérêt croissant suscité au Canada à la suite de la signature d'accords avec le Mexique et le Chili. Du point de vue des urbanistes, il y a deux raisons pour lesquelles nous devrions nous intéresser à l'Amerique latine : d'abord, pour capitaliser sur l'expérience de l'Amerique latine, qui a eu à faire face à une croissance rapide avec des ressources minimales (faire plus avec moins) et, ensuite, pour tirer profit d'un marché en émergence qui exige des services professionnels. À l'aide d'exemples propres à l'Amerique latine, nous abordons trois problématiques majeures : la décentralisation des fonctions gouvernementales, le rôle du secteur privé dans la prestation des services publics et la participation accrue des ONG au processus de prise de décisions en matière d'aménagement. Finalement, des secteurs clés sont identifiés dans lesquels nous pouvons offrir l'expérience canadienne en urbanisme.

Characterization of Pinpoint, a CRISPR/RNA-aptamer-mediated base editor, and its therapeutic potential in hemoglobinopathies
Creators: name: Tan, Victor Ming Wei

description: Genome editing has traditionally relied on the formation of targeted DNA double strand breaks (DSB), followed by activation of DNA repair pathways such as homology-directed repair (HDR) and non-homologous end joining (NHEJ). Unfortunately, this approach is marred by (1) random insertions and deletions (indels) (NHEJ), (2) limited to proliferating cells and general lack of efficiency in non-dividing somatic cells (HDR). To overcome these limitations, we developed a base editing (BE) system that directly converts one type of DNA nucleotide bases into another. Our Pin-point BE strategy incorporates elements of Clusters of Regularly Interspaced Short Palindromic Repeats (CRISPR) and RNA-aptamer mediated recruitment. We engineered a nuclease-deficient Streptococcus pyogenes Cas9 nickase combined with RNA-aptamer containing sgRNA to recruit DNA/RNA editing enzymes capable of C·G→T·A conversions by cytidine deamination. We previously demonstrated effectiveness of our system on episomal DNA editing as well as endogenous gene editing on various cell models. To further improve on our system, we incorporated upgrades to our modular system in using various orthologous deaminases from other species. We then assessed their efficacies and editing capabilities on previously tested endogenous sites and characterized their Cas-dependent and Cas-independent off-target effects. To this end, we found several orthologs from Anolis carolinesis (green lizard) and Myotis lucifugus (bat) to have improved base editing efficiencies as well as differing editing window along the protospacer element.We further applied our BE technology for therapy against hemoglobinopathies such as beta-thalassemia and sickle cell disease (SCD). During human development, globin protein expression switches from fetal globin (?) to adult globin (β). Transcription proteins BCL11A and ZBTB7A bind ?-globin promoters at key stretches of DNA, repressing its expression upon maturation of the fetus to birth. Interestingly, naturally occurring mutations in these regions has been found in patients with milder symptoms. These mutations disrupt repressor binding to the ?-globin promoters, thus alleviating repression of the gene, leading to expression of fetal hemoglobin which compensates for deficient adult hemoglobin. We showed that our BE system is able to recapitulate these mutations, providing evidence of a promising therapy towards these hemoglobinopathies. Ultimately, we showed improvements to our BE technology as well as possible use for therapeutic applications, all independent of the DSBs and HDR necessary for previous technologies.
The city and its region or the region and its city?

description: An explicitly critical perspective of the Conference theme is used to inform an exploration of the contemporary city-region planning challenge and to argue for an alternative operative philosophy to the current centre-periphery dichotomy framework that has made it natural to think about the city and its region, rather than the other way around. A paradigm shift is proposed, based on a new operative philosophy - the territory/function dialectic, whereby city-region planning is reframed as an exercise in mediating territorial autonomies and functional interdependencies. Making such a shift is expected to entail planners learning new roles such as eco-citistate "placemakers," "agent collaborateurs," "common market-eers," and "cosmopolitan convivants."
description: L'auteur adopte une perspective explicitement critique du thème du congrès pour éclairer I'examen du défi urbanistique contemporain de la ville-région et pour appuyer une nouvelle philosophie fonctionnelle du cadre de la dichotomie centre-périphérie actuelle qui montre comment il est naturel d'envisager « la ville et sa région », plutôt que l'inverse. Il propose un changement de paradigme, fondé sur une nouvelle philosophie fonctionnelle - la dialectique territoire-fonction, où l'aménagement de la ville-région est réorganisé à titre d'exercice de médiation des autonomies territoriales et des interdépendances fonctionnelles. Ce changement obligera les urbanistes à apprendre de nouveaux rôles, notamment ceux de « concepteur éco-urbain », « d'agent collaborateur », « d'européiste » et de « convivant cosmopolite ».

description: A self-built laser projection system for optical transverse strain measurements in tensile testing is presented. The setup based on laser diode modules, CCD (Charge-Coupled Device) array detectors, and standard optomechanical components is proposed to be a low-cost system for testing polymer samples. The optical setup is mobile and can easily be mounted on a tensile test machine. Circular cross-sectional changes in polymer diameter were detected with ten-micrometre resolution and stress-strain curves obtained by a tensile test machine. The article describes signal processing using the open-source programming language R, and the transverse deformation of the polymer sample is evaluated in two perpendicular planes. The results obtained by the optical system may be used to accurately describe the models of energy-based mechanical properties of polymers for complex load conditions.

description: We study a model of dilute oriented loops on the square lattice, where each loop is compatible with a fixed, alternating orientation of the lattice edges. This implies that loop strands are not allowed to go straight at vertices, and results in an enhancement of the usual O(n) symmetry to U(n). The corresponding transfer matrix acts on a number of representations (standard modules) that grows exponentially with the system size. We derive their dimension and those of the centraliser by both combinatorial and algebraic techniques. A mapping onto a field theory permits us to identify the conformal field theory governing the critical range, $n \le 1$. We establish the phase diagram and the critical exponents of low-energy excitations. For generic n, there is a critical line in the universality class of the dilute O(2n) model, terminating in an SU(n+1) point. The case n=1 maps onto the critical line of the six-vertex model, along which exponents vary continuously.

description: Academic law librarians are dealing with three large crises. First, they have little budget money to use to build new library buildings. Second, they have little room to add new books to their collections. Third, the shelving space they do have is being reclaimed for group or collaborative study spaces.This study investigates one response to these crises: a vigorous deselection program. While much literature for deselection in libraries in general, few academic resources deal with deselection in academic law libraries. To determine what criteria might guide academic law librarians in evaluating which books to retain, the research interviewed academic law librarians to discover what they thought were important deselection criteria to consider.
