HORIZON RUN 3: TOPOLOGY AS A STANDARD RULER

Speare, Robert,Gott, J. Richard,Kim, Juhan,Park, Changbom IOP Publishing 2015 The Astrophysical journal Vol.799 No.2

<P>We study the physically self-bound cold dark matter halo distribution, which we associate with the massive galaxies within Horizon Run 3, to estimate the accuracy of the determination of the cosmological distance scale measured by the topology analysis. We apply the routine 'Contour 3D' to the 108 Mock Survey of p steradians out to redshift z = 0.6, which effectively corresponds to the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) survey, and compare the topology with that of a Gaussian random phase field. We find that given three separate smoothing lengths. = 15, 21, and 34 h(-1) Mpc, the least chi(2) fit genus per unit volume (g) yields a 1.7% fractional uncertainty in smoothing length and angular diameter distance to z = 0.6. This is an improvement on former calibrations and presents an error estimate competitive with baryon acoustic oscillation scale techniques. We also present three-dimensional graphics of the Horizon Run 3 spherical mock survey to show a wealth of large-scale structures of the universe that are expected for surveys like BOSS.</P>

Fibrin affects short-term in vitro human mesenchymal stromal cell responses to magneto-active fibre networks

Spear, Rose L.,Symeonidou, Antonia,Skepper, Jeremy N.,Brooks, Roger A.,Markaki, Athina E. Techno-Press 2015 Biomaterials and biomedical engineering Vol.2 No.3

Successful integration of cementless femoral stems using porous surfaces relies on effective periimplant bone healing to secure the bone-implant interface. The initial stages of the healing process involve protein adsorption, fibrin clot formation and cell osteoconduction onto the implant surface. Modelling this process in vitro, the current work considered the effect of fibrin deposition on the responses of human mesenchymal stromal cells cultured on ferritic fibre networks intended for magneto-mechanical actuation of in-growing bone tissue. The underlying hypothesis for the study was that fibrin deposition would support early stromal cell attachment and physiological functions within the optimal regions for strain transmission to the cells in the fibre networks. Highly porous fibre networks composed of 444 ferritic stainless steel were selected due to their ability to support human osteoblasts and mesenchymal stromal cells without inducing untoward inflammatory responses in vitro. Cell attachment, proliferation, metabolic activity, differentiation and penetration into the ferritic fibre networks were examined for one week. For all fibrin-containing samples, cells were observed on and between the metal fibres, supported by the deposited fibrin, while cells on fibrin-free fibre networks (control surface) attached only onto fibre surfaces and junctions. Initial cell attachment, measured by analysis of deoxyribonucleic acid, increased significantly with increasing fibrinogen concentration within the physiological range. Despite higher cell numbers on fibrin-containing samples, similar metabolic activities to control surfaces were observed, which significantly increased for all samples over the duration of the study. It is concluded that fibrin deposition can support the early attachment of viable mesenchymal stromal cells within the inter-fibre spaces of fibre networks intended for magneto-mechanical strain transduction to in-growing cells.

Reevaluation of the Metabolic Essentiality of the Minerals - Review -

Spears, J.W. Asian Australasian Association of Animal Productio 1999 Animal Bioscience Vol.12 No.6

Essential metabolic functions have been identified for seven macrominerals (calcirum, phosprorus, magnesium, sodium, potassium, chloride, and sulfur), and eight microminerals (cobalt, copper, iodine, iron, manganese, molybdenum, selenium, and zinc). Major functions for each of these minerals are summarized. Considerable research suggests that chromium is also essential and that it functions by facilitating insulin activity. Studies are reviewed which indicate that chromium supplementation of animal diets may: 1) increase glucose removal from blood, 2) reduce carcass fat and increase lean in nonruminants, 3) alter egg cholesterol content, and 4) enhance immunity and disease resistance in ruminants. A number of other minerals including nickel, boron, vanadium, arsenic, silicon, lithum, and lead have been reported to be essential, but specific metabolic functions have not been defined for any of these elements. Limited research in poultry suggests that boron may be of practical significance in some instances.

Eliot’s Exilic Imagination

Jewel Spears Brooker 한국T.S.엘리엇학회 2015 T.S. 엘리엇 연구 Vol.25 No.3

T. S. Eliot, like Conrad, Joyce, Pound, Beckett, and other greats of his generation, had an exilic imagination. Displaced from the country of their birth, they were conscious of being strangers in an uneasy world. This essay outlines Eliot’s sense of displacement and homelessness from 1914 to the late 1950s, with emphasis on the effect that the impulse to return had on his major poems. The Waste Land is a poem of personal and cultural exile, Ash-Wednesday is an ode expressing both the pain of exile and the hope of return, and Four Quartets is a composition that reconfigures exile as a life-long spiritual odyssey.

The War Within: Feeling and Intellect in Early Eliot

Jewel Spears Brooker 한국T.S.엘리엇학회 2009 T.S. 엘리엇 연구 Vol.19 No.2

T. S. Eliot’s career began with a struggle between poetry and philosophy. The agon featured Dante, whose work informed Eliot’s earliest poems, and F. H. Bradley, whose thought was the subject of his Ph.D. thesis. Eliot’s most detailed discussion of the connection between poetry and philosophy is contained in his 1926 Clark Lectures at Cambridge University, published as Varieties of Metaphysical Poetry. He defines the “philosophic poet” in Bradleyean terms as one who “enlarges immediate experience” by “drawing within the orbit of feeling and sense what had existed only in thought” (VMP 55,51). Philosophic poetry is work of the “highest intensity, in which the thought is fused into poetry at a very high temperature” (VMP 50). Eliot argues that Dante’s poetry perfectly illustrates the integration of feeling and intelligence, both in life and in art. In this paper, I explore Eliot’s attempt to negotiate the claims of philosophy and poetry, as represented by Bradley and Dante, and his ultimate decision to abandon a promising career in philosophy for a tenuous career in poetry. Eliot’s ambition of becoming a “philosophic poet,” combining Bradley and Dante, was realized in his Dantean sequences Ash-Wednesday and Four Quartets.

The Ties that Bind in The Elder Statesman

Jewel Spears Brooker 한국T.S.엘리엇학회 2010 T.S. 엘리엇 연구 Vol.20 No.2

A major theme of Eliot’s work is the difficulty of genuine and lasting human connection. Connection can be based on a positive (love) or a negative (guilt). The thesis of this essay is that certain shared actions constitute a tie that binds―especially shared actions that have been concealed, secrets kept between two guilty parties. Complicity in such actions binds partners together socially, psychologically, and morally. “Friendships” based on shared secret sins last for a lifetime; they can be denied, but they cannot be nullified, and finally, they must be acknowledged in public. In The Elder Statesman, crime, sex, and blood (family) are the ties that bind.

What T. S. Eliot Learned from Dante

Jewel Spears Brooker 한국T.S.엘리엇학회 2011 T.S. 엘리엇 연구 Vol.21 No.2

Dante is one of those poets, Eliot once said, that one only grows up to at the end of one’s life. In Eliot’s work, growing up to (learning from) his Italian master has three primary dimensions. The first is psychological, and it has to do with a perception, in reading, of feelings and ideas as unified. The second is aesthetic, and it has to do with poetry, with understanding how to achieve such unification in art. And the third is moral, and it has to do with social and spiritual unification through the cultivation of humility.

Connectivity of Collaborative Robots in Partially Observable Domains

Suranga Hettiarachchi,PaulM. Maxim,William M. Spears,Diana F. Spears 제어로봇시스템학회 2008 제어로봇시스템학회 국제학술대회 논문집 Vol.2008 No.10

Collaborative information processing is vital for a swarm of robots tasked with many different applications. Swarm connectivity is necessary for achieving good collaboration. Our approach to this is a physics-based autonomous robot framework that acts as a distributed mobile sensor network that is capable of maintaining high connectivity during self-organization and movement. The framework, called Physicomimetics, is a robust control scheme built on local interactions between the robots, making it highly scalable, adaptive, and cost effective. This paper presents connectivity results of mobile sensor networks on two partially observable domains ?formation movement through obstacle fields and the self-organization of chain formations.

DIETARY SILICA EFFECTS ON MINERAL METABOLISM IN LAMBS

Prabowo, Akhmad,Spears, J.W. Asian Australasian Association of Animal Productio 1992 Animal Bioscience Vol.5 No.2

Eighteen wether lambs averaging 32 kg were used to determine the effects of dietary silica, added as silicic acid, on mineral metabolism. Lambs were fed 1200 g daily of a coastal Bermuda grass based diet supplemented with either 0, .5 or 1.5% silicic acid. A 7-d total collection of urine and feces was conducted after lambs had adjusted to the dietary treatments for 19 days. Urinary excretion of silica was higher (p<.01) in lambs fed added silicic acid. Ruminal soluble concentrations of manganese tended to be lower (p<.10) and apparent absorption and retention of manganese were lower (p<.05) in lambs supplemented with silicic acid compared to control lambs. Apparent absorption and retention of calcium were slightly lower (p<.10) in silicic acid fed lambs. No differences in urinary between lambs fed .5 and those given 1.5% silicic acid. Phosphorus, magnesium, iron, zinc and copper absorption and retention were not affected by treatment.
