    Metal-organic frameworks (MOFs) are an exciting class of porous materials with a large variety of potential applications. Finding and analysing new MOF systems is important for the development of new technologies, including in medicine and pollution capture. Furthermore, using high quality in situ single crystal X-ray diffraction (scXRD) is necessary to understand how MOFs capture, store and release gas molecules. Presented here are novel frameworks based on 2,3-dihydroxyterephthalic acid and the M(II) metal ions Mg, Ni, Co, Ca and Cu. So far nine different phases have been solved structurally with six new to this body of work. SIMOF-3 (St Andrews Isoreticular MOF) can be formed from Mg, Ni and Co. It contains a disordered pillar linker that may be flexible. The Ca phase SIMOF-4 is denser with a phase change to an even denser phase on solvent removal. However, this material did show utility as an anode in a sodium battery. Cu produced two distinct phases both showing breathing behaviour. The more stable phase has shown excellent capacity for the storage and release of the drug molecules Ibuprofen, Flutamide and caffeine as well as the adsorbtion of the medicinal gas nitric oxide (NO). In addition, in situ scXRD studies have been performed on Ni-CPO-27 and Co-4,6-dhip to investigate the binding of the polar gases NO, CO and SO₂. This has uncovered the relative binding strengths of these gases, their competitive interactions with water and the presence of physisorbed binding sites. Finally, a series of mixed metal Ni/Cu CPO-27 analogues were synthesised that could release preadsorbed NO on addition of moisture as well as catalytically generate NO from S-nitrosoglutathione. The framework and its stability in biological media were investigated with Ni₀.₁Cu₀.₉-CPO-27 showing excellent all round properties suitable for inclusion into future medical devices

    Selected letters of Matthew Arnold

    No full text
    Selected Letters of Matthew Arnold is a collection of 216 letters by the Victorian poet and critic Matthew Arnold (1822-88). The letters are arranged chronologically and grouped under four headings that represent stages in Arnold's adult life and career: "The Young Poet, 1844-51 " "The Married Poet and Inspector of Schools, 1851-57," "The Professor of Poetry and Literary Critic, 1857-67," and "The Critic of Society and Religion 1867-88." In these letters, Arnold, who wrote no autobiography, tells the story of his life and expresses his intimate views on a variety of subjects. In order to include the largest possible selection of interesting letters from both previously published and unpublished sources, some of the letters are given in part while others are given in their complete form. Along with the most important letters from the 1895 edition by G. W. E. Russell - principally made up of letters to family members - and the 1932 edition of letters to Author Hugh Clough by Howard F. Lowry, this new collection incorporates many significant letters from other sources, including 49 previously unpublished letters. Most of the Russell and Lowry letters have been newly edited, using the manuscript collections at Yale University and Balliol College, Oxford

    Generalized monotonicity and the proximal point algorithm

    No full text
    We study the proximal point algorithm when the operator of interest is metrically subregular and satisfies a submonotonicity property. The latter property can be viewed as a quantified weakening of the standard definition of a monotone operator. Our main result gives a condition under which, locally, the proximal point algorithm generates sequences which are linearly convergent to a zero of the underlying operator. General properties of our notion of submonotonicity are also explored as well as connections to other concepts in the literature. This is a detailed and improved version of results reported in the extended abstract published in the Proceedings of the 35th RAMP Symposium, Tokyo, November 2023

    Buddhist Bubblegum: Esoteric Buddhism in the Creative Process of Arthur Russell

    No full text
    Buddhist Bubblegum is a study on the role of esoteric Buddhism in the creative process of singer, cellist, composer, and producer, Arthur Russell (1951-1992). Largely ignored during his lifetime, Russell’s work has aroused mass interest in the 21st century. Tim Lawrence’s biography (Hold On to Your Dreams) and Matt Wolff’s documentary (Wild Combination) offer significant and well-researched insight into the artist’s life and work. Little attention, however, has been given to Russell’s actual compositions and musical notations, while his creative process is often reduced to allusion and mystery. After spending several years with the scores and notebooks in Russell’s archive, as well as interviewing many of his friends and collaborators, I discovered a large body of work strategically guided by Vajrayana Buddhism. From his teenage years on a Buddhist commune until his last performances in New York, Russell sought to directly apply Vajrayana techniques--mantra, meditation, visualization, sadhana rituals--to his music, which he called “Buddhist bubblegum.” The initial chapters outline the esoteric spiritual influences that guided Russell’s music. I explore his life-long practice of Shingon Buddhism, his later engagement with Tibetan Buddhism, his study of traditional North Indian music, as well as his use of numerology and astrology. The next chapters explore Russell’s early scores and the maturation of his compositional style. This development culminates with Russell’s largest work, Instrumentals, which was inspired by his Buddhist teacher. This leads us into an in-depth look at the making of Instrumentals, where we outline the unique “matrix” system of composition that Russell devised to compose the work. Next we see how Russell’s “matrix” system continued to inform his later works--his “mutant disco” opus, 24>24 Music, his orchestral collaboration with Robert Wilson, Tower of Meaning, and his work with the Singing Tractors. Finally, we explore the unique conceptual process which Russell used in composing his final full-length work, World of Echo. Buddhist Bubblegum outlines the creative process of an American artist whose unprecedentedly cross-genre work uniquely fused spiritual and musical disciplines

    NT 510 The Gospel of Matthew

    No full text
    General Description A basic course in inductive Bible studies. The primary purpose is to enable the student to begin developing an inductive approach to Bible study, especially in the areas of observation and interpretation. Parts of the Gospel of Matthew are used to demonstrate and to practice a methodical approach which can be used in other biblical books. Some of the main themes of the Gospel are highlighted in the process. This course seeks to introduce the student to the inductive method of biblical study, and to direct this interpretive approach to the Gospel of Matthew. This orientation implies several things, including (1) an emphasis upon methodology and methodological concerns, and (2) a strong commitment to direct, independent study of the biblical text, with secondary sources (e.g., commentaries, grammars, dictionaries of the Bible) to be consulted by the student only after extensive, firsthand study has been completed. The English Bible (RSV/NRSV) will serve as the basis for study. Students with facility in Greek are encouraged to make use of the original whenever possible.https://place.asburyseminary.edu/syllabi/3579/thumbnail.jp

    A complex and punctate distribution of three eukaryotic genes derived by lateral gene transfer

    No full text
    Abstract Background Lateral gene transfer is increasingly invoked to explain phylogenetic results that conflict with our understanding of organismal relationships. In eukaryotes, the most common observation interpreted in this way is the appearance of a bacterial gene (one that is not clearly derived from the mitochondrion or plastid) in a eukaryotic nuclear genome. Ideally such an observation would involve a single eukaryote or a small group of related eukaryotes encoding a gene from a specific bacterial lineage. Results Here we show that several apparently simple cases of lateral transfer are actually more complex than they originally appeared: in these instances we find that two or more distantly related eukaryotic groups share the same bacterial gene, resulting in a punctate distribution. Specifically, we describe phylogenies of three core carbon metabolic enzymes: transketolase, glyceraldehyde-3-phosphate dehydrogenase and ribulose-5-phosphate-3-epimerase. Phylogenetic trees of each of these enzymes includes a strongly-supported clade consisting of several eukaryotes that are distantly related at the organismal level, but whose enzymes are apparently all derived from the same lateral transfer. With less sampling any one of these examples would appear to be a simple case of bacterium-to-eukaryote lateral transfer; taken together, their evolutionary histories cannot be so simple. The distributions of these genes may represent ancient paralogy events or genes that have been transferred from bacteria to an ancient ancestor of the eukaryotes that retain them. They may alternatively have been transferred laterally from a bacterium to a single eukaryotic lineage and subsequently transferred between distantly related eukaryotes. Conclusion Determining how complex the distribution of a transferred gene is depends on the sampling available. These results show that seemingly simple cases may be revealed to be more complex with greater sampling, suggesting many bacterial genes found in eukaryotic genomes may have a punctate distribution.</p

    What Are the Results of Product-Price Studies and What Can We Learn From Their Differences?

    No full text
    In recent years many economists have analyzed whether international trade has contributed to rising U.S. wage inequality by changing relative product prices. In this paper I survey the findings of nine product-price' studies which together demonstrate how the methodology of product-price studies has evolved. I then synthesize the findings of these nine studies and draw two main conclusions. The first conclusion is that this literature has a refined set of empirical strategies for applying the Stolper-Samuelson theorem to the data from which important methodological lessons can be learned. The second main conclusion is that despite the methodological progress that has been made, research to date still has fundamental limitations regarding the key question of how much international trade has contributed to rising wage inequality. Most importantly, more work needs to link exogenous forces attributable to international trade to actual product-price changes.

    The proximal point algorithm without monotonicity

    No full text
    We study the proximal point algorithm in the setting in which the operator of inter- est is metrically subregular and satisfies a submonoticity property. The latter can be viewed as a quantified weakening of the standard definition of a monotone operator. Our main result gives a condition under which, locally, the proximal point algorithm generates at least one sequence which is linearly convergent to a zero of the underlying operator. General properties of our notion of submonotonicity are also explored as well as connections to other concepts in the literature
