description: We investigate dynamic hysteresis and Barkhausen noise in ferromagnetic materials with a huge number of parallel and rigid Bloch domain walls. Considering a disordered ferromagnetic system with strong in-plane uniaxial anisotropy and in-plane magnetization driven by an external magnetic field, we calculate the equations of motion for a set of coupled domain walls, considering the effects of the long-range dipolar interactions and disorder. We derive analytically an expression for the magnetic susceptivity, related to the effective demagnetizing factor, and show that it has a logarithmic dependence on the number of domains. Next, we simulate the equations of motion and study the effect of the external field frequency and the disorder on the hysteresis and noise properties. The dynamic hysteresis is very well explained by means of the loss separation theory.

The Clipper, 1893-1902 : an example of radical journalism
Creators: name: Shimmins, JD
Publisher: name: University Of Tasmania
Year: 2023

description: James Paton founded the Clipper in April 1893 as a radical, socialist weekly newspaper through which he aimed to express his ideals and review life in Tasmania at the turn of the century. In his time as editor (which ran until the end of 1902), the Clipper included political commentary, and reported on social and sporting events. Study of the Clipper provides an insight into the lives and activities of Tasmanians, particularly those of the late nineteenth century working class: This bright, breezy paper was the first direct and successful appeal to the Tasmanian working class and was an important step towards creating a democratic self consciousness in the people.
Essays on jump risk factors in financial forecasting
Creators: name: Yu, Bo
Publisher: name: No Publisher Supplied
Year: 2020

description: This dissertation consists of two essays that explore issues in empirical asset pricing and portfolio management using high-frequency financial econometrics techniques. The first essay investigates the cross-sectional return predictability of various jump risk factors. The second essay develops sparse portfolio variance forecast models that incorporate informative realized jump risk factors. In Chapter 2, we study the cross-sectional relationship between (small and large) jump variation measures and future stock returns, based on portfolio sorts and Fama-MacBeth type regressions. We document that a new risk factor, signed small jump variation (i.e., the difference between upside and downside small jump variation measures), strongly predicts the cross-sectional variation in future returns. Constructed based on a data-driven threshold, signed small jump variation has stronger predictive power for future returns than other realized risk measures, in the cross-section. We also conduct various experiments (e.g., event studies, etc.) to further explore the linkages between different jump risk measures and economic factors relating to news in the markets. We show that large jumps are closely associated with ``big'' news. While such news related information is embedded in large jump variation, the information is generally short-lived, and dissipates too quickly to provide marginal predictive content for subsequent weekly returns. By contrast, we find that small jumps are more likely to be diversified away than large jumps, thus tend to be more closely associated with idiosyncratic risks, and are therefore more likely to be driven by liquidity conditions and trading activity.In Chapter 3, we investigate whether the decomposition of realized covariance matrices of portfolios of asset returns into components based on both the signs and magnitudes of the underlying high-frequency returns is useful for forecasting. In particular, our decomposition separates realized covariation into components based on signs (positive and negative) and magnitudes (continuous, small jump, and large jump). Sparse portfolio variance forecast models, which are constructed by utilizing the most informative covariance components, produce significant improvements in predictive accuracy. We show that such predictive gains can be traced to the identification of short-lived pricing signals associated with co-jumps.

description: We investigate the optimal dynamical decoupling sequence for a qubit coupled to an ohmic environment. By analytically computing the derivatives of the decoherence function, the optimal pulse locations are found to satisfy a set of nonlinear equations which can be easily solved. These equations incorporates the environment information such as high-energy (UV) cutoff frequency ω_c, giving a complete description of the decoupling process. The solutions explain previous experimental and theoretical results of locally optimized dynamical decoupling (LODD) sequence in high-frequency dominated environment, which were obtained by purely numerical computation and experimental feedback. As shown in numerical comparison, these solutions outperform the Uhrig dynamical decoupling (UDD) sequence by one or more orders of magnitude in the ohmic case.

description: This article extends the scope of empirical likelihood methodology in three directions: to allow for plug-in estimates of nuisance parameters in estimating equations, slower than $\sqrt{n}$-rates of convergence, and settings in which there are a relatively large number of estimating equations compared to the sample size. Calibrating empirical likelihood confidence regions with plug-in is sometimes intractable due to the complexity of the asymptotics, so we introduce a bootstrap approximation that can be used in such situations. We provide a range of examples from survival analysis and nonparametric statistics to illustrate the main results.

Teacher interpretation and application of graphed behavioral data throughout the RTI process
Creators: name: Belmonte, Colleen Patricia Ann
Publisher: name: No Publisher Supplied

description: Students with or at-risk of High Incidence Disabilities (HID) experience a multitude of negative outcomes. To intervene early, many schools have elected to implement evidence-based practices within Response to Intervention (RTI). RTI targets the academic and behavioral progress of students deemed “at risk” for HID with increasingly intensive interventions. Throughout the RTI process, teachers play a critical role in data-based decision-making by collecting, interpreting, and applying behavioral data. However, very limited research has explored teacher ability, confidence, or usefulness to engage in this role. As such, the purpose of this study was to explore pre-service and in-service teachers’ ability, confidence, willingness, and perceived usefulness to interpret and apply behavioral data before and after a brief behavior analytic training titled “Collecting, Interpreting, and Applying Graphed Behavioral Data” (CIA-GBD), and the factors that influenced each outcome. One hundred and one participants completed a survey and 24 participants attended CIA-GBD. Results indicated that, prior to CIA-GBD, teachers were somewhat able to find specific information in the graphed data, but were challenged to interpret the effects of intervention or make decisions based on the data. After training, teacher ability increased in all aspects; with the exceptions of data application. In addition, teacher confidence and willingness to interpret and apply graphed behavioral data increased. These data suggest the benefits of a brief training to increase teacher data use and application.
The short and long-term effects of the ISLE approach on high school physics students' attitudes and development of science-process abilities

description: The National Research Council, American Association of Physics Teachers (AAPT), the Next Generation Science Standards (NGSS), and Advanced Placement Physics 1 and 2 guidelines all set the goals of engaging students in experimentation and authentic scientific reasoning while developing normative concepts to help them develop essential skills and competencies necessary to succeed in our rapidly changing world. As a result, activities that place greater emphasis on reasoning and argumentation and engage students in experimental practices are finding their ways into both high school and university-level courses. One way to meeting the above goals is through the Investigative Science Learning Environment (ISLE) approach, which fully aligns with national recommendations. The ISLE approach focuses on two major issues: engaging students in the activities that mirror scientific practice, while constructing and applying new knowledge; and empowering them as learners during that process. This ISLE approach forms the foundation of this study.While student learning through the ISLE approach was studied extensively in college classrooms, very few studies have been done at the high school level. We do not know whether or how learning through the ISLE approach helps students meet the standards set by national organizations. In addition, there are no studies of the long-term effects of learning physics through the ISLE approach. To address these gaps this multiphase mixed-methods study has two goals: to explore how first-year high school physics students who learn physics through the ISLE approach show changes in their science-process abilities, attitudes, and motivation towards experimental science; and to determine the long-term effects of such learning. The study was conducted in two phases. In the first phase, written laboratory reports, attitudes surveys, and confidence surveys were collected from 230 first-year honors physics students over a three-year period. In the second phase, a survey was sent to alumni who learned physics through the ISLE approach. A subset of these students participated in interviews and a focus group. The research aims to address not only how high school students develop science-process abilities, but how the opportunity to revise and improve their work affects this development. Furthermore, this research aims to learn how student attitudes concerning investigative learning and experimental design change over the course of a school year as well as how student mindset and motivation factor into these changes. Finally, this research aims to better understand the long-term effects of learning in an investigative physics course on student attitudes, learning strategies, and performance in future educational experiences and careers.

Early development and application of proof-like reasoning: longitudinal case studies
Creators: name: Krupnik, Victoria
Publisher: name: No Publisher Supplied
Year: 2020

description: This study traces three primary school students’ longitudinal development of mathematical ideas and ways of reasoning while solving a strand of counting problems. The students worked on well defined, open-ended counting problems of variable difficulty in various settings: pairs, whole class settings, task-based interviews and small groups. Video-taped data, transcripts, and student work are analyzed for cognitive growth in reasoning, attentive to the social elements of collaboration in problem solving. Data include individual and group co-construction of justifications for solutions. Video narratives (VMCAnalytics) describe the students’ learning progressions. Student dialogue and co-constructions that fostered their development are identified and displayed in the 13 published video narratives linked to the analyses. For each student, how do their recognition of patterns, use of strategies and representations, display of justifications and forms of reasoning about solutions to counting tasks develop over time and how might each journey be displayed with a learning progression using video data? Analyses revealed local and global recognition for enumeration of outcomes (by recursive strategies), invention of composite operations, connection between tasks, rule generalization, and direct reasoning by cases, induction, controlling for variables. Particular forms of reasoning are identified for each student. The following cognitive and social factors revealed that learning occurred collaboratively, in a variety of settings. Students were attentive to the counter examples/arguments posed by others and worked to convince others about their arguments that were “proof like” in structure. The longitudinal study showed how earlier ideas became the foundation for building later ideas, represented in more sophisticated ways. The results have implications for effective mathematical practices, such as collaborative learning, and attention to providing justifications for solutions. These pedagogical approaches can be incorporated in curriculum design, can supplement approaches to teacher professional development. The learning progressions can offer teachers an approach to formative assessment of student reasoning on solving counting tasks.

description: Ion exchange between intracellular and extracellular spaces is the basic mechanism for controlling cell metabolism and signal transduction. This process is mediated by ion channels and transporters on the plasma membrane, or intracellular membranes that surround various organelles, in response to environmental stimuli. Macroautophagy (hereafter referred to as autophagy) is one of the lysosomal-dependent degradation pathways that maintains homeostasis through the degradation and recycling of cellular components (e.g., dysfunctional proteins and damaged organelles). Although autophagy-related (ATG) proteins play a central role in regulating the formation of autophagy-related member structures (e.g., phagophores, autophagosomes, and autolysosomes), the autophagic process also involves changes in expression and function of ion channels and transporters. Here we discuss current knowledge of the mechanisms that regulate autophagy in mammalian cells, with special attention to the ion channels and transporters. We also highlight prospects for the development of drugs targeting ion channels and transporters in autophagy.

Seed banks, community dynamics and species persistence in 5 Tasmanian temporary wetlands

description: Water regime has been found to be the most important factor in determining vegetation patterns in wetlands. The present study investigates the short and long-term persistence of plant communities within 5 temporary Tasmanian lentic wetlands and- resistance and resilience of wetland communities to dry periods. Within each wetland an aquatic herbaceous and sedge-dominated zone were sampled seasonally between February, 1997 and November, 1998, to test difference between and within wetlands, and their relations to water depth. Four glasshouse experiments using sediments taken from 9 permanent quadrats per vegetation type per wetland (zone) were used to determine temporal and spatial differences in seed banks in relation to season, vegetation type, depth, germination treatment and water regime. The relationship between the seed bank and extant vegetation was investigated. A functional group classification generated similar groups to Brock and Casanova (1997). These were: a) submerged; b) amphibious fluctuation responder; c) amphibious fluctuation tolerator-emergent; d) amphibious fluctuation tolerator-saturated/mudflat; and e) terrestrial. The vegetation communities within the 5 temporary wetlands proved not resistant to changes in water level. Large differences in percentage cover were associated with hydrological changes over the 2 year period. However, the communities were able to resurrect relatively quickly after both short and long term dry periods. The seed bank experiments indicated that Tasmanian temporary wetlands have speciesrich persistent seed banks, and, therefore, the potential for future regeneration. In general, species in the seed bank could be related to species found in the extant vegetation. However, at any given time, species can be found in the seed bank and not present in the extant vegetation, or vice versa. Both seed banks and vegetative regeneration were important mechanisms for species persistence in the vegetation communities of the 5 wetlands.

description: We prove that the Korteweg-de Vries initial-value problem is globally well-posed in $H^{-3/4}(\R)$ and the modified Korteweg-de Vries initial-value problem is globally well-posed in $H^{1/4}(\R)$. The new ingredient is that we use directly the contraction principle to prove local well-posedness for KdV equation at $s=-3/4$ by constructing some special resolution spaces in order to avoid some 'logarithmic divergence' from the high-high interactions. Our local solution has almost the same properties as those for $H^s (s>-3/4)$ solution which enable us to apply the I-method to extend it to a global solution.

description: We survey four nearby irregular galaxies for radio supernova remnants (SNRs) using deep (1 sigma ~ 20 microJy), high resolution (~20 pc) VLA continuum data at 20, 6, and 3.6 cm. We identify discrete sources in these galaxies and use radio spectral indices and H alpha images to categorize them as SNRs, H II regions, or background radio galaxies. Our classifications are generally in good agreement agreement with the literature. We identify a total of 43 SNR candidates: 23 in NGC 1569, 7 in NGC 4214, 5 in NGC 2366, and 8 in NGC 4449. Only one SNR--the well-studied object J1228+441 in NGC 4449--is more luminous at 20 cm than Cas A. By comparing the total thermal flux density in each galaxy to that localized in H II regions, we conclude that a significant fraction must be in a diffuse component or in low-luminosity H II regions.

description: The aim of this document is to summarize all activities in individual demos but also the overall coordination that was needed among demos. As can be seen from the document, this coordination contained many follow-up steps. Therefore, it required close cooperation not only within the demo teams, but also at the WP5 level or across WPs. This coordination was also very important because some demos took place in both IP4MaaS and Ride2Rail projects (in particular in Athens and Padua) in parallel, so it took a lot effort to synchronize all activities between these projects and at the same time cooperation with CFM side, which was responsible for proper integration into the IP4 ecosystem. For this reason, this deliverable illustrates important phases of the demos life cycle, in particular:• demo preparation,• demo execution, • demo evaluation.This structure is used for each demo so that the reader is presented with the same content of the information, but at the same time can compare different approaches, e.g. within the user engagement strategy, number of demonstrated functionalities, number of testers, feedback from them, etc. All information is described in detail in individual reports. The last chapter then tries to summarize all the activities, but above all to emphasize the differences in the individual demos. Complete information is provided in individual report D5.2-5.7. These reports are published on the project website https://www.ip4maas.eu/
The influence of milk fat composition on the properties of chocolate
Creators: name: Smith, JM
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of this research was to assess the seasonal change in milk fat composition and determine the effects that these changes had on properties of chocolate, such as snap, hardness, shelf life, gloss, temperability and sensory attributes. Milk samples from two lactation seasons were collected. The fat was extracted and analysed by gas-liquid chromatography for the fatty acid and triglyceride composition. These samples were also analysed by nuclear magnetic resonance to determine the solid fat content at various temperatures. The relative proportions of the fatty acids and triglycerides in the milk fat samples were found to vary throughout the lactation period, showing distinct seasonal trends. The variation in the relative proportions of the fatty acids in the milk fat influenced the relative proportions of specific triglycerides in the milk fat. The solid fat content (SFC) of the milk fat also varied throughout the lactation period with the lowest SFC, or the softest milk fat, being present in spring and the highest SFC, or the hardest milk fat, being present in summer. The SFC was influenced by the fatty acid and triglyceride composition of the milk fat. The seasonal trends in the relative proportions of the fatty acids and the triglycerides and the percentage of solid fat in the milk fat were the same for both lactation seasons assessed.
Computer treatment of spider phobia
Creators: name: Smith, Kathryn Louise
Publisher: name: University Of Tasmania
Year: 2023

description: Exposure-based therapies are considered to be most effective in the treatment of all phobias and have grown to become the psychological treatment of choice. A variable that is combined with exposure-based therapies and enhances phobic improvement is modelling. Past research has shown the mastery technique to be the most effective modelling procedure rather than the coping technique. A putative mechanism for treatment effect may be through the internalization of locus of control. Due to the prevalence of simple phobias, the logistic and economic demands in providing such a treatment make the delivery of therapy to sufferers difficult. Computer administered behaviour therapies represent an innovative solution and have been shown to be effective in controlled trials using subjects with clinical diagnoses.. The present research addresses the limitations of previous instructional computer programs through the development of a simulated computer program for the treatment of spider phobia combining the principles of exposure therapy and modelling techniques. The aims of the study include whether scenario specificity is important in the treatment of specific phobias, whether the program facilitates self-exposure in-vivo, and whether phobic improvement produces a complementary shift in ratings of locus of control. Spider phobics (N=45) were randomly allocated ¬¨‚àëto one of three treatment groups: elevator scenario (ES) ; spider scenario (SS); or spider scenario without treatment principles (SSWTP). All subjects completed three computer treatment sessions. Thirty-eight subjects completed the 6 to 12 month follow up. Results showed a significant improvement rate for performance (time taken to reach the maximum score) within each group across the three computer treatment sessions. No significant shift from external to internal locus of control was found within groups following treatment. Computer scenario specificity was found not to constitute an important factor in the treatment of spider phobics as in addition to the elimination of some important treatment principles. Exposure activities were facilitated to a degree by the treatmenl: program and maintained at the follow up. No additional reported exposure activities however, were endorsed during the follow-up period. Reported self-exposure activities were shown to correlate positively with phobic improvement. All groups showed significant phobic improvement following the treatment as measured on a variety of instruments. The methodological limitations of this study are discussed.

The behavior of the dark energy and the expansion history of the Universe depend heavily on the parameters of the model $α$, $β$ and $γ$. It is very interesting that the age problem of the well-known three old objects can be alleviated in this models.

Estimation of genetic and environmental parameters of some blood serum components in dairy cattle
Creators: name: Basuthakur, Arun Kumar
Publisher: name: University of British Columbia
Year: 2011

description: The variations due to environmental and genetic causes in the blood serum components in dairy cattle were estimated from blood samples collected from 226 Holstein and Holstein-Ayrshire cross bred female calves and cows, at the University of British Columbia, Oyster River Research Farm number two. The blood serum samples were analyzed for protein, albumin, globulin, calcium, inorganic phosphorus, cholesterol, blood urea nitrogen (B.U.N.), uric acid, creatinine, alkaline phosphatase, and serum glutamic oxaloacetic transaminase (S.G.O.T.), by SSM 12/60 multichannel sequential analyzer. The albumin and globulins α₁, α₂, β₁, β₂, and γ levels in the blood were estimated using thin plate agarose gel electrophoresis. The age in days as a source of variation (fitted within physiological groups) significantly affected most of the blood serum components in the young female calves and heifers, bred heifer, lactating non-pregnant, lactating pregnant and dry animal groups. The days pregnant was a significant source of variation in the different types of serum proteins, B.U.N, and alkaline phosphatase in the present study. The days lactating fitted as a source of variation in the lactating non-pregnant animals significantly affected the blood serum components-cholesterol, B.U.N., globulin α₁ and β₂. The days lactating fitted as a source of variation in lactating pregnant animals accounted for a significant amount of variation only in cholesterol. The lactation traits (Kg. milk, Kg. milk fat, Kg. milk protein and Kg. lactose produced by the animal in the milking prior to collection of blood sample) as sources of variation in the milking animals significantly affected the blood serum components cholesterol, uric acid, globulins α₁ and β₂. The physiological groups (young animals, bred heifers, lactating non-pregnant group, lactating pregnant group and dry animal group) accounted for the major portion of the variation in almost all the blood serum components in the present study. The linear function of age when fitted across groups was important and accounted for a significant amount of variation in almost all of the blood serum components. Breed groups fitted as percentage Holstein (I. Holstein, II. 75 to 62 percent Holstein, III. 50 to 25 percent Holstein) accounted for significant amounts of variation only in three blood serum components, uric acid, globulin α₂ and globulin β₁.
Some aspects of the stratigraphy, structure and petrology of the Precambrian rocks of Tasmania
Creators: name: Spry, AH
Publisher: name: University Of Tasmania
Year: 2023

description: The Precambrian rocks of Tasmania may be divided into two main groups, the unmetamorphosed sediments (?younger Precambrian) and the metamorphic rocks (? older Precambrian). The metamorphic rocks from Frenchmans Cap, the headwaters of the Mersey and Forth Rivers, the lower Pieman River, Ulverstone and Port Davey, show that the regional metamorphism of the Frenchman Orogeny contained at least two phases of deformation, F\\(_1\\) and F\\(_2\\). The highest grade of metamorphism was reached during F\\(_1\\) at Frenchmans Cap but the isoclinal folds were produced during F\\(_2\\). It is postulated that the metamorphic zones formed during F\\(_1\\) were folded into large recumbent folds during F\\(_2\\). The fabric of the metamorphic rocks is shown to be the result of repeated deformation. Quartz, mica etc. have a preferred orientation and a symmetry related to macroscopic features such as lineation. The metamorphic rocks belong to several subfacies of the Greenschist Facies. A thick succession of unmetamorphosed quartz-sandstones, subgreywackes, siltstones, slates and dolomite occurs widely throughout the north-west of Tasmania. The relations between the metamorphosed (\older\") and unmetamorphosed (\"younger\") groups are obscure mainly because both were refolded during the Devonian. A comparison of their tectonic styles suggests that the two are separated by a tectonic and metamorphic episode. The mapped major structures in the metamorphic rocks are of Devonian age and the Palaeozoic Holds may be unfolded to leave bedding foliations and the axial surfaces of isoclinal folds in a sub - horizontal position. Basic and ultrabasic igneous rocks which intrude the meta-morphosed sediments have been metamorphosed to amphibolites greenschists and eclogites. The Cooee Dolerites form a very extensive dyke swarm which intruded the unmetamorphosed sediments during the Penguin Movement of the late Precambrian."

description: This work presents a new multilayered microfluidic platform, manufactured using a rapid and cost-effective xurography technique, for the detection of drug concentrations in sweat. Textile fabrics made of cotton and polyester were used as a component of the platform, and they were positioned in the middle of the microfluidic device. In order to obtain a highly conductive textile, the fabrics were in situ coated with different amounts of polyaniline and titanium dioxide nanocomposite. This portable microfluidic platform comprises at least three layers of optically transparent and flexible PVC foils which were stacked one on top of the other. Electrical contacts were provided from the edge of the textile material when a microfluidic variable resistor was actually created. The platform was tested in plain artificial sweat and in artificial sweat with a dissolved cytostatic test drug, cyclophosphamide, of different concentrations. The proposed microfluidic device decreased in resistance when the sweat was applied. In addition, it could successfully detect different concentrations of cytostatic medication in the sweat, which could make it a very useful tool for simple, reliable, and fast diagnostics

description: We present a dynamical model of the high mass X-ray binary LMC X-1 based on high-resolution optical spectroscopy and extensive optical and near-infrared photometry. From our new optical data we find an orbital period of P=3.90917 +/- 0.00005 days. We present a refined analysis of the All Sky Monitor data from RXTE and find an X-ray period of P=3.9094 +/- 0.0008 days, which is consistent with the optical period. A simple model of Thomson scattering in the stellar wind can account for the modulation seen in the X-ray light curves. The V-K color of the star (1.17 +/- 0.05) implies A_V = 2.28 +/- 0.06, which is much larger than previously assumed. For the secondary star, we measure a radius of R_2 = 17.0 +/- 0.8 solar radii and a projected rotational velocity of V_rot*sin(i) = 129.9 +/- 2.2 km/s. Using these measured properties to constrain the dynamical model, we find an inclination of i = 36.38 +/- 1.92 deg, a secondary star mass of M_2 = 31.79 +/- 3.48 solar masses, and a black hole mass of 10.91 +/- 1.41 solar masses. The present location of the secondary star in a temperature-luminosity diagram is consistent with that of a star with an initial mass of 35 solar masses that is 5 Myr past the zero-age main sequence. The star nearly fills its Roche lobe (~90% or more), and owing to the rapid change in radius with time in its present evolutionary state, it will encounter its Roche lobe and begin rapid and possibly unstable mass transfer on a timescale of a few hundred thousand years.

description: The aim of the Deliverable 5.2 “Final report on Barcelona Demonstration execution” is to presentthe preparation and execution activities of Barcelona Demonstration site taking place as a part of the IP4MaaS project within the framework of the Shift2Rail Joint Undertaking (now Europe Rail). The demonstrated technologies were selected functionalities of the Travel Companion application. The demonstration consisted in integration of the services of certain Transport Service Providers(TSPs) of Barcelona Metropolitan Area considering technical, legal, and business aspects and then recruiting testers/volunteers to test and provide feedback on the Travel Companion application. The testers had to download the application and use it while travelling by means of Public Transport (i.e., buses, metro) and combined itineraries with private transport on demand services (test multimodality) and to provide us feedback regarding the selected functionalities with the use of the online User Satisfaction Index questionnaire form. The USI questionnaire was developed as part of the WP3, task T3.2 “User satisfaction with IP4 solutions”.To this end, the Deliverable 5.2 outlines the various activities that took place as part of coordination and fostering of the Barcelona Demo preparation and execution, reports the contribution of the Barcelona demonstration team to technological integration. Finally, this deliverable reports the internal testing results of the integrated technologies and the outcomes and findings of the Barcelona demonstration activities.

description: Let k be a field of characteristic different from 2. There can be an obstruction for an indecomposable principally polarized abelian threefold (A,a) over k to be a Jacobian over k. It can be computed in terms of the rationality of the square root of the value of a certain Siegel modular form. We show how to do this explicitly for principally polarized abelian threefolds which are the third power of an elliptic curve with complex multiplication. We use our numeric results to prove or refute the existence of some optimal curves of genus 3.

Electromagnetic Boundary Conditions Defined in Terms of Normal Field Components

description: A set of four scalar conditions involving normal components of the fields D and B and their normal derivatives at a planar surface is introduced, among which different pairs can be chosen to represent possible boundary conditions for the electromagnetic fields. Four such pairs turn out to yield meaningful boundary conditions and their responses for an incident plane wave at a planar boundary are studied. The theory is subsequently generalized to more general boundary surfaces defined by a coordinate function. It is found that two of the pairs correspond to the PEC and PMC conditions while the other two correspond to a mixture of PEC and PMC conditions for fields polarized TE or TM with respect to the coordinate defining the surface.

description: In this work the theoretical and experimental investigations of Co2TiZ (Z = Si, Ge, or Sn) compounds are reported. Half-metallic ferromagnetism is predicted for all three compounds with only two bands crossing the Fermi energy in the majority channel. The magnetic moments fulfill the Slater-Pauling rule and the Curie temperatures are well above room temperature. All compounds show a metallic like resistivity for low temperatures up to their Curie temperature, above the resistivity changes to semiconducting like behavior. A large negative magnetoresistance of 55% is observed for Co2TiSn at room temperature in an applied magnetic field of 4T which is comparable to the large negative magnetoresistances of the manganites. The Seebeck coefficients are negative for all three compounds and reach their maximum values at their respective Curie temperatures and stay almost constant up to 950 K. The highest value achieved is -52muV/K m for Co2TiSn which is large for a metal. The combination of half-metallicity and the constant large Seebeck coefficient over a wide temperature range makes these compounds interesting materials for thermoelectric applications and further spincaloric investigations.

description: We study the flux and the angular power spectrum of gamma-rays produced by Dark Matter (DM) annihilations in the Milky Way (MW) and in extra-galactic halos. The annihilation signal receives contributions from: a) the smooth MW halo, b) resolved and unresolved substructures in the MW, c) external DM halos at all redshifts, including d) their substructures. Adopting a self-consistent description of local and extra-galactic substructures, we show that the annihilation flux from substructures in the MW dominates over all the other components for angles larger than O(1) degrees from the Galactic Center, unless an extreme prescription is adopted for the substructures concentration. We also compute the angular power spectrum of gamma-ray anisotropies and find that, for an optimistic choice of the particle physics parameters, an interesting signature of DM annihilations could soon be discovered by the Fermi LAT satellite at low multipoles, l<100, where the dominant contribution comes from MW substructures with mass M>10^4 solar masses. For the substructures models we have adopted, we find that the contribution of extra-galactic annihilations is instead negligible at all scales.
