Structural polysaccharide chemistry with analytical applications to lemon gum
Creators: name: Gibney, Kelly Blair
Publisher: name: University of British Columbia
Year: 2011

description: A gas chromatographic method has been developed whereby the following compounds may be determined quantitatively and simultaneously: ethylene glycol, glycerol, erythritol, threitol, arabinose, xylose, mannose, galactose and glucose. These products correspond to the constituent parts of periodate oxidized, borohydride reduced polysaccharides. Quantitative analysis of the fractions obtained on total and partial hydrolysis of such polyalcohols provides a new and powerful analytical tool in polysaccharide chemistry. Optimum conditions for the Smith degradation of a polysaccharide have been illustrated by a detailed analysis of lemon gum. A new method for the reduction of uronic acids in poly- and oligosaccharides has been developed. Reduction can be carried out after only esterification of the uronic acids. Reaction at this stage avoids possible degradation or fractionation during esterification and subsequent saponification of polysaccharide hydroxyl groups. Good levels of reduction [75%] have been achieved with reduction of highly branched lemon gum. Silylated polyhydroxy compounds and galacturonic acid were examined by proton magnetic resonance spectroscopy. The trimethylsilyl [TMS] protons of such ethers and esters show good separation from one another. Analysis of the trimethylsilyl proton peaks provides information concerning the number and degree of subsitution of hydroxyl and acid functions present in the parent molecule. Signal strength due to the nine protons on each trimethylsilyl group provides a chemical means of signal enhancement. Analysis was carried out on 2 mg. of a minor TMS glucofuranose derivative. Lemon gum has been analysed by the method of Lindberg et al [8l]. Analysis of lemon gum is the first example of the application of partially methylated alditol acetate mass spectroscopy to a plant gum. The results of this analysis are in good agreement with previous analysis of this gum.
Controls on southern ocean phytoplantkton production - a systems approach
Creators: name: Balari, EAM
Publisher: name: University Of Tasmania
Year: 2023

description: Plankton ecosystems play a significant part in the global cycle of carbon by contributing ‚ÄövÑvÆ40% of total annual primary productivity. Changes are expected in response to warming, increased ocean stratification, altered supply of iron as a limiting micronutrient, and ecosystem structures. To diagnose these effects, numerical models of plankton ecology have become a key approach. This thesis examines the Nutrient Phytoplankton Zooplankton Detritus (NPZD) ecosystem model of Oschlies & Garcon [1999], and especially the modifications required to simulate phytoplankton biomass in naturally iron-fertilized Southern Ocean waters. This provides perspectives on the sensitivity of Southern Ocean ecosystems to global change. The NPZD model was used to simulate the phytoplankton bloom that forms in natural iron-fertilized waters of the Kerguelen plateau and adjacent High Nutrient Low Chlorophyll (HNLC) waters. Sensitivity to mixed layer depth and temperature was found to be negligible in comparison to zooplankton grazing, which also strongly modulated the ability of increased iron availability to affect biomass via phytoplankton growth rates. Direct comparison with satellite chlorophyll estimates showed that the base model could not achieve chlorophyll concentrations greater than ‚ÄövÑvÆ0.6 mg M-3 , in comparison to the ‚ÄövÑvÆ2.7 mg M-3 of chlorophyll observed in the Kerguelen bloom. Incorporating an indirect simulation of iron-fertilization provided only a small improvement. An increase in zooplankton grazing (by a factor of 7) was required to achieve the high peak bloom biomass. To match the seasonal cycle and both summer maximum and winter minimum biomass concentrations, it was also necessary to impose seasonal cycles in key photosynthetic parameters (a - initial slope of the photosynthesis/irradiance curve, and umax - maximal growth rate). The same model was used to examine the response of plankton ecosystems to temporary iron fertilizations. The model was able to simulate the phase and amplitude patterns of the SOIREE bloom in Antarctic waters, given increases in a and ,u‚ÄövÑvª,‚ÄövÑvª, similar to those observed in the field (a factor of 2.5 over 13 days). Simulating a series of SOIREE-like experiments at different times of the seasonal cycle showed that while blooms induced in spring resulted in high surface chlorophyll levels, only blooms induced in summer resulted in both high chlorophyll and high potential carbon export. These findings also emphasized the importance of low overwintering biomass of phytoplankton and zooplankton to the spring biomass peak. Expanding the simulations to all latitudes of the Southern Ocean revealed distinct variations in the intensity of responses to iron fertilization, and suggested that the optimal time and location for iron fertilization in terms of potential carbon export is early summer in the Subantarctic zone.

An input-output model of the Tasmanian economy
Creators: name: Edwards, GC
Publisher: name: University Of Tasmania
Year: 2023

description: Input-output economics is an internationally accepted method of economic planning and decision making but the construction of input-output models within Australia has not been extensive even though a national transactions table was constructed early in the era of input-output. Over the last decade the situation has been changing with national tables, now constructed on a regular basis and regional studies proliferating. The major obstacle to the preparation of sub-national input-output tables is the paucity of commodity and trade data so that for most regional studies the emphasis has been on surveys. For two States, Western Australia and Tasmania, both commodity and trade data are tabulated by the Australian Bureau of Statistics thus providing the basis for the construction of input-output models principally from secondary data. An interindustry study for W.A. appeared in 1967. The aim of this study is to produce a Tasmanian transactions table together with the associated tables of coefficients and to quantify the structural economic inter-relationships by determining the output, income and employment multipliers of Tasmanian industries. In Chapter 2 the input-output system and the assumptions are presented together with the mathematical relationships. The closed model and the dynamic input-output system incorporating capital coefficients, both extensions to the basic open static model, are also described. The forms of input-output analysis are outlined in Chapter 3 including structural and multiplier analysis and simulation.

description: In the decoupling limit of DGP, Pi describes the brane-bending degree of freedom. It obeys second order equations of motion, yet it is governed by a higher derivative Lagrangian. We show that, analogously to the Einstein-Hilbert action for GR, the Pi-Lagrangian requires Gibbons-Hawking-York type boundary terms to render the variational principle well-posed. These terms are important if there are other boundaries present besides the DGP brane, such as in higher dimensional cascading DGP models. We derive the necessary boundary terms in two ways. First, we derive them directly from the brane-localized Pi-Lagrangian by demanding well-posedness of the action. Second, we calculate them directly from the bulk, taking into account the Gibbons-Hawking-York terms in the bulk Einstein-Hilbert action. As an application, we use the new boundary terms to derive Israel junction conditions for Pi across a sheet-like source. In addition, we calculate boundary terms and junction conditions for the galileons which generalize the DGP Pi-lagrangian, showing that the boundary term for the n-th order galileon is the (n-1)-th order galileon.

A comparison of methodologies in the measurement of olfactory sensitivity under conditions of non-adaptation and co-adaptation.
Creators: name: Fraser, John W.
Publisher: name: University Of Tasmania
Year: 2023

description: An investigation into the relative efficiency of Threshold and Signal Detectability measures of olfactory Sensitivity was undertaken using isopropyl alcohol as stimulus. Intensive testing of seven subjects under adaptive and non-adaptive conditions revealed that the Signal Detectability paradigm, although theoretically desirable because of its allowance for the subject's response bias, was difficult to implement because of the prolonged testing required. A variance of the rating technique involving multiple stimulus concentration presentations in a three-hour testing session was attempted. Results in the nonadapting environment indicated that the method was more effective than single-stimulus concentration presentations. However reliable results under adapting conditions were obtained In the case of one subject only. As a comparison, the constant stimulus method was used to obtain threshold using a procedure similar to Cheesman's and Mayne's group threshold determinations, but modified for individual subject testing. Practice and learning effects were noted and their relevance discussed. The Cheesman hypothesis viz, that adapting odour concentration and threshold elevation obey a linear logarithmic relation which is characteristic of the adapting and test stimulus compounds was confirmed in two subjects only. Reasons for non-confirmation include the extended adapting stimulus concentration range, subject boredom and inadequate control of the stimulus; the latter factors being a consequence of prolonged testing. The sniff-bottle and air-dilution forms of stimulus presentation were employed, although not with the same subjects. Thus a direct contrast of these presentation methods was not possible. However results were generally more consistent with the air-dilution technique. The feasibility of an odour classification based on subject responses during adaptation rather than on molecular parameters was evaluated and the difficulties likely to be encountered in employing Signal Detectability measures of sensitivity was discussed.

THE ROLE OF STYLISTIC DEVICES IN COGNITION AND COMMUNICATION
Creators: name: Sharifova, Diyora
Publisher: name: Zenodo
Year: 2025

description: Stylistic devices form the critical basis for all cognitive processes that include thinking and remembering and transmitting messages. The article evaluates how rhetoric and figurative language techniques support mental operations like conceptual mapping and inference along with memory retention and how they mold message expression during communication. The article demonstrates how metaphor and repetition along with irony and personification and simile operate across storytelling for instruction as well as everyday conversation and literary content by using theories from discourse pragmatics and cognitive linguistics. The discussion shows how stylistic devices simultaneously support mental processes and improve person-to-person message delivery through numerous real-world examples.

description: AGILE is a small space mission of the Italian Space Agency (ASI) devoted to gamma-ray and hard-X astrophysics, successfully launched on April 23 2007. The AGILE Payload is composed of three instruments: a gamma-ray imager based on a tungsten-silicon tracker (ST), for observations in the gamma ray energy range 30MeV - 50GeV, a Silicon based X-ray detector, SuperAGILE (SA), for imaging in the range 18keV - 60keV and a CsI(Tl) Mini-Calorimeter (MCAL) that detects gamma rays or charged particles energy loss in the range 300keV - 100MeV. MCAL is composed of 30 CsI(Tl) scintillator bars with photodiode readout at both ends, arranged in two orthogonal layers. MCAL can work both as a slave of the ST and as an independent gamma-ray detector for transients and gamma-ray bursts detection. In this paper a detailed description of MCAL is presented together with its performance.

Adaptive equalisation of television systems
Creators: name: Furmage, Stewart Greer
Publisher: name: University Of Tasmania
Year: 2023

description: The introduction of long transmission paths with time varying characteristics, television relay switching facilities and colour television creates the need for high quality adaptive equalisation of television signals. The purpose of this thesis is to investigate techniques which may be used to provide such an adaptive equalising facility. An adaptive equaliser is defined as one which can track a time varying transmission channel characteristic. A discussion of the adaptive equaliser best suited to the requirements of the television system is presented and a detailed theoretical and practical investigation of this equaliser undertaken. The practical investigation was made possible with the construction of an experimental equalising system.
Christmas Oratorio "Nativitatis Christi" (PART 1: Prelude for Organ, 6 pp.)
Creators: name: Elia, Anthony J.
Publisher: name: Columbia University
Year: 2011
Subjects: Music

description: The Christmas Oratorio “Nativitatis Christi” was written mostly in the Fall of 2011. The first four parts were written in September and October of 2011 (including the Organ Prelude), while the latter parts were begun in the Spring of 2012. As of July 2013, the oratorio is incomplete, with at least three more sections to be written (in Swahili-French, Russian, and German). The Oratorio was written for the diverse community of Union Theological Seminary in New York City. The texts of the Oratorio are biblical, but are in different languages, including Latin, Greek, English, French, Swahili, Russian, and German. The Magnificat is a work, which is meant to convey the high church tradition of Latin liturgy, while the Benedictus is a blessing meant to encompass the divergence and convergence of church traditions (Soprani (“High” Church language)=Latin, Bass (“Low” Common language)=English, Central Voices of Tenor/Alti=Greek, the ancient foundational language used here, anchoring the tradition and the music to a pivot point). The other parts of this work have similar explanations, which will be provided when available in Academic Commons. This first part is a prelude for organ.

Sonata #3 for Solo Piano "The Dodecahedral Sonata" (PART 12)
Creators: name: Elia, Anthony J.
Publisher: name: Columbia University
Year: 2013
Subjects: Music

description: The Piano Sonata #3 (Named the “Dodecahedral Sonata” because of its 12-parts or “sides”) was written in June 2013 for NYC pianist Ishmael Wallace, over the course of ~48 hours. Over the last decade and a half, the composer struggled to complete a full solo piano sonata, attempting several times. While attempts had been made in the late 1990s and early 2000s to write such a piece, it wasn't until 2008, with the Piano Sonata #1, that a serious undertaking was made. This first sonata was (inspired by) and composed after hearing a piano work commissioned for Elliot Carter played on the radio by Chicago pianist Winston Choi. Unfortunately, only 25 pages of this one-movement sonata were completed, and by 2013, the manuscript had been misplaced. In the Spring of 2013, the Piano Sonata #2 was begun around the 100th Anniversary of Stravinsky’s “Rite of Spring” Premiere --a homage to Stravinsky's work. Six pages were composed of this next sonata (the “Uncontrolled Sonata”), after which the composer’s notation software malfunctioned. Soon after, the composer had a conversation with his friend, the pianist Ishmael Wallace. After this conversation about compositional styles with Mr. Wallace, which took place on a Wednesday (June 5th), two days later, on Friday, June 7th, the composer began working on the Piano Sonata #3, which is presented here, and completed the 12-part work by that same Sunday, June 9th. Each part has a distinct flavor to it; Part 10, the shortest of all the composer’s works, consists of “10-note” multi-dimensional 16th note in one measure. Though performers and critics might find this “gimmicky,” it’s meant to express the various forms of musical expression in the complexity of the sonata form, and how it has been altered, augmented, and re-created in this present work. Part 12 is a recapitulation, almost identical to Part 1 with slightly broader complexity of notation, and both the first and last sections are to be performed with bold and sweeping power. As with most of the composer’s works, minimalism in dynamics and articulation offers performers a greater sense of freedom and flexibility of interpretation.

Cumacean zoogeography : the zoogeography of Tasmanian shallow water marine zoobenthos exemplified by some Cumacea
Creators: name: Dartnall, Alan J.
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis incorporates the results of studies into the distributions of the Cumacea whose members are one of the groups of animals living in shallow water sands off eastern Tasmania. My approach assumes that patterns of animal distribution exist. This may be regarded as an expression of belief. However, as MacArthur (1927) has pointed out most investigations of biological distributions reveal pattern at some scale. The approach is supported also by the work of Taylor, Woiwod and Perry (1978) who suggested that spatial randomness is highly improbable because the behavioural responses of living organisms mediate dispersive processes. 1.1 Layout The text of this account is divided into two main sections. The first deals with the zoogeography of shallow water cumaceans in eastern Tasmania. The second section contains an account of cumacean spatial distribution at the benthic interface and, briefly, the place of these animals in the water column. 1.2 Timing This project commenced in March, 1977. The formal cut-off point for literature survey was June, 1979. All literature quoted after that date results from browsing or the intermission of friendly gatekeepers. 1.3 Statement of Intent During a period of eleven years as a working naturalist in Tasmania the geographic distribution of the Tasmanian marine fauna has been of interest. The concept of the Maugean marine province (Iredale and May, 1916) proved a useful working hypothesis if only because it provided a framework upon which to hang observed distributions. This descriptive approach was emphasized in a paper upon Tasmanian littoral biogeography (Dartnall, 1974). Other work which is referred to later in this text suggested that marine animal distributions along the east coast of Tasmania were interrupted by a discontinuity at the approximate latitude of Maria Is. (c. 42o 31'S). Vernacular evidence from other working zoologists offered nothing to refute this view. It was with some surprise, therefore, to read the work of King (1972) and to discover that the distribution of littoral algae did not support the concept of a Maugean marine province. Both King and myself have suggested that marine biogeographic regions should reflect oceanographic conditions and that investigation of Maugean distributions might continue profitably offshore. This thesis is the result of that suggestion. The pathways followed during this work are summarized in a flow diagram following the conclusions. Logical pathways are direct but labyrinthine logic plots its own web. The actual routes followed are indicated.

Development of direct current heteropolar machines with superconducting field windings
Creators: name: Green, MJI
Publisher: name: University Of Tasmania
Year: 2023

description: A practical and theoretical study of direct current heteropolar machines with superconducting field windings was conducted with the aim of proving their technical feasibility and to indicate their advantages and disadvantages over machines of more conventional design. These studies were conducted in conjunction with extensive tests on small superconducting D.C. machines of various formats. Three stages of machine development occurred. In the first stage machine the superconducting field winding was shielded from armature reaction fluxes with the aid of iron and compensating windings. In the second stage machine the superconducting field winding was subjected to the full effects of the armature reaction fluxes. Tests conducted with these machines indicated that the operation of the superconducting field winding was not influenced by the flow of armature currents. A third, four pole superconducting D.C. machine which exhibits all the advantages gained by using superconductors in the field windings has been constructed. This machine has most of the construction features of a full size prototype machine for future industrial applications. As a result of difficulties encountered in inducing the superconducting state into the field windings operational tests on this machine could not be conducted. Possible reasons for the difficulties are discussed with the result that some of the reasons are rejected and measures that could overcome the difficulties are forwarded. The project began with no experience in cryogenics, cryostat design and construction nor superconductivity. Consequently details of practical techniques utilised during the project are included. Continued development of superconducting heteropolar D.C. machines should prove that the design and operation of a prototype machine with a rating in excess of 10 MW is possible. This is essential if this type of machine is to make any impact in the future. Providing the expectation that voltage per commutator bar limits can be substantially increased is realised, machine ratings that are limited only by armature cooling should be possible.

The glacial history of the upper Mersey Valley
Creators: name: Hannan, D
Publisher: name: University Of Tasmania
Year: 2023

description: In the upper Mersey Valley there have been three and possibly four glaciations during the Pleistocene. From youngest to oldest they are named the Rowallan Glaciation, the Arm Glaciation, and the Croesus Glaciation. In addition sediment from a Tertiary glaciation and a Lower Palaeozoic glaciation have been recognised. The Rowallan Glaciation covered the smallest area of the three Pleistocene glaciations. The glacier formed a reticulate system with the main source an icecap on the Central Plateau, and occupied an area of approximately 282 sq km. Major valleys were almost completely filled with ice and the glacier terminated in at least six ice lobes. In the region the Rowallan Glaciation covered an area of approximately 282 sq km. The lowest point reached was 390 m above sea level in the Mersey Valley and the equilibrium line altitude for the system was 1050 m, which indicates a snowline some 930 m below present and a drop in the average annual temperature of 6.2¬¨‚àûC. The Rowallan Glaciation attained its maximum before or about 13,400 ¬¨¬± 600 yr BP and deglaciation was well advanced or complete by 9760 ¬¨¬± 720 yr BP. The Arm Glacial system was larger in extent than the Rowallan Glaciation and at its maximum occupied an area of approximately 500 sq km. The , lowest point reached was in the Mersey Valley at 330 m and it had an equilibrium line altitude of 950 m. This suggests a snowline 1030 m below present and a drop in the average annual temperature of 6.7¬¨‚àûC. The age of the Arm Glaciation is not known but estimated to be in excess of 100,000 years BP. The Croesus Glaciation is the oldest glaciation and had a very large extent, completely blanketing the upper Mersey Valley. It terminated far beyond the area of this study. The lowest altitude reached, the equilibrium line altitude and the estimated temperature drop during the glacial maximum are unknown. Some sediments of Croesus age show a reversed remanent detrital magnetism and thus have a minimum age of 730,000 years BP. The Tertiary and upper Palaeozoic glaciations are postulated on the basis of scattered outcrops of lithified till in the region. The Rowallan, Arm and Croesus glaciations of the upper Mersey Valley are tentatively correlated with other glaciations in Tasmania, namely the Margaret, Henty and Linda glaciations of the West Coast Ranges. The Rowallan Glaciation is also tentatively correlated with the glaciation of the Snowy Ranges on the mainland of Australia and with radiocarbon dated glaciations of New Zealand and Chile.

description: We compute the static-light meson spectrum with N_f = 2 flavours of sea quarks using Wilson twisted mass lattice QCD. We consider five different values for the light quark mass corresponding to 300 MeV < m_PS < 600 MeV and we present results for angular momentum j = 1/2, j = 3/2 and j = 5/2 and for parity P = + and P = -. We extrapolate our results to physical quark masses and make predictions regarding the spectrum of B and B_s mesons.

description: The orbitally degenerate A-site spinel compound FeSc2S4 has been experimentally identified as a ``spin-orbital liquid'', with strong fluctuations of both spins and orbitals. Assuming that the second neighbor spin exchange J2 is the dominant one, we argued in a recent theoretical study [Chen et al., Phys. Rev. Lett. 102, 096406 (2009)] that FeSc2S4 is in a local ``spin-orbital singlet'' state driven by spin orbit coupling, close to a quantum critical point, which separates the ``spin-orbital singlet'' phase from a magnetically and orbitally ordered phase. In this paper, we refine further and develop this theory of FeSc2S4 . First, we show that inclusion of a small first neighbor exchange J1 induces a narrow region of incommensurate phase near the quantum critical point. Next, we derive the phase diagram in the presence of an external magnetic field B, and show that the latter suppresses the ordered phase. Lastly, we compute the field dependent dynamical magnetic susceptibility $χ(k, ω; B)$, from which we extract a variety of physical quantities. Comparison with and suggestions for experiment are discussed.

description: Two-tailed asymptotic inferences for the ratio R=p2/p1 of two independent proportions have been well covered in the published literature. However, not very much has been written about one-tailed asymptotic inferences. This paper evaluates 63 different methods for realizing such inferences (hypothesis tests and confidence intervals). In general it is noted that: (a) the one-tailed inferences require at least 80 observations per sample, compared to the 40 observations necessary for two-tailed inferences; (b) the traditional methods do not perform well; (c) the methods selected for each case are not always the same; and (d) the optimal method is the ‘approximate adjusted score’ method (ZA1 in this paper), which is not always reliable, or ‘Peskun´s score’ method (ZP0 in theis paper), which is always reliable but is very conservative. The two selected methods provide an confidence interval that is obtained through an explicit formula.
Transcending Big Bang in Loop Quantum Cosmology: Recent Advances

description: We discuss the way non-perturbative quantization of cosmological spacetimes in loop quantum cosmology provides insights on the physics of Planck scale and the resolution of big bang singularity. In recent years, rigorous examination of mathematical and physical aspects of the quantum theory has led to a consistent quantization which is consistent and physically viable and some early ideas have been ruled out. The latter include so called `physical effects' originating from modifications to inverse scale factors in the flat models. The singularity resolution is understood to originate from the non-local nature of curvature in the quantum theory and the underlying polymer representation. Using an exactly solvable model various insights have been gained. The model predicts a generic occurrence of bounce for states in the physical Hilbert space and a supremum for the spectrum of the energy density operator. It also provides answers to the growth of fluctuations, showing that semi-classicality is preserved to an amazing degree across the bounce.

description: Аннотация. В статье изучено влияние боевых действий 1940–1943 годов в Северной Африке на военную стратегию Германии. Изучено, как успехи и неудачи немецких войск в Северной Африке влияли на германские позиции на Восточном фронте. Сделан вывод, что североафриканская кампания стала дорогостоящей авантюрой для стран Оси. Первоначальные неудачи итальянских войск, потребовавшие переброски немецких подкреплений в Северную Африку, отвлекли внимание и ресурсы от операций против Советского Союза. В свою очередь, победы союзников не только привели к значительным потерям итало-немецких войск, но и предотвратили захват Ближнего Востока, что позволило сохранить важный трансиранский маршрут поставок. Германия и Италия были вынуждены выделить значительные силы и ресурсы для поддержки своих войск в Северной Африке. Эти ресурсы, особенно весной и летом 1941 года, могли быть использованы на Восточном фронте. Африканская кампания способствовала общему истощению ресурсов Германии и растягиванию ее коммуникаций. Необходимость постоянной поддержки войск в Северной Африке отвлекала внимание немецкого руководства от других театров боевых действий.  

Abstract. The article examines the impact of the 1940–1943 fighting in North Africa on German military strategy. It examines how the successes and failures of German troops in North Africa affected German positions on the Eastern Front. It concludes that the North African campaign was a costly gamble for the Axis powers. The initial failures of the Italian troops, which required the transfer of German reinforcements to North Africa, diverted attention and resources from operations against the Soviet Union. In turn, the Allied victories not only led to significant losses for the Italo-German troops, but also prevented the capture of the Middle East, which made it possible to preserve the important trans-Iranian supply route. Germany and Italy were forced to allocate significant forces and resources to support their troops in North Africa. These resources, especially in the spring and summer of 1941, could have been used on the Eastern Front. The African campaign contributed to the general depletion of Germany's resources and the stretching of its communications. The need for constant support of troops in North Africa diverted the attention of the German leadership from other theaters of military operations.
Driving forces of cluster evolution – Growth and lock-in of two German packaging machinery clusters

description: This paper explores the driving forces for divergent trajectories of cluster evolution within the same branch of industry using the example of two packaging machinery clusters located in the German regions of Schwaebisch-Hall and Mittelhessen. Between 1998 and 2010 the Schwaebisch-Hall cluster recorded an increase in employment of almost two thirds. On the other hand, employment in the Mittelhessen cluster declined by about 15% and the cluster is characterised by negative functional and cognitive lock-in. This study tackles the existing lack of comparative in-depth longitudinal case studies with regard to cluster evolution. In doing so, the driving forces from recent conceptual approaches to cluster dynamics are exemplified empirically, which has rarely been done before. It is pointed out that dynamics at individual firm level (e.g. routines, spin-offs) are equally important – albeit highly interdependent – as those dynamics of relations (e.g. learning, rivalry, policy) and those operating at a systemic level (e.g. cluster heterogeneity, markets). Therefore we consider conceptual approaches to cluster evolution, which combine several driving forces to really understand changes, as necessary.

description: The confidence band of functions is complicated by the over-smoothing problem and the residual distribution. In this paper, we use bootstrap and data-sharpening methods to establish a general confidence band. The construction is simple and the band is narrower than existing estimation methods. At the same time, a technique based on quantiles makes the confidence band more controllable and damps down the stochastic error term. Afterwards, we conduct a limited simulation to illustrate that the proposed band performs better than existing ones. Finally, we show the theoretical properties of the results and prove them.

description: The effect of anisotropic order parameter to specific heat of anisotropic two-band superconductors in BCS weak-coupling limit are investigated. An analytical specific heat jump and the numerical specific heat are shown by using anisotropic order parameters, and the electron-phonon interaction and non-electron-phonon interaction. The two model of anisotropic order parameters are used for numerical calculation that we find little effect to the numerical results . The specific heat jump of, and superconductors can fit well with the both of them. By comparing to experimental data overall range of temperature, the best fit is ,, and superconductors, respectively.
