description: We apply tomography, a general method for reconstructing 3-D distributions from multiple projections, to reconstruct the momentum distribution of electrons produced via strong field photoionization. The projections are obtained by rotating the electron distribution via the polarization of the ionizing laser beam and recording a momentum spectrum at each angle with a 2-D velocity map imaging spectrometer. For linearly polarized light the tomographic reconstruction agrees with the distribution obtained using an Abel inversion. Electron tomography, which can be applied to any polarization, will simplify the technology of electron imaging. The method can be directly generalized to other charged particles.

description: This article offers a comprehensive comparison of oppositional behaviour in European Union (EU) affairs in six countries: Austria, Denmark, Germany, Ireland, Sweden and the United Kingdom. By drawing on a unique data set of hand-coded statements made by Members of Parliament during European Affairs Committee (EAC) meetings it provides new knowledge on political opposition. The data uncover that there is more opposition expressed in EU affairs than has been assumed by previous research. The results also reveal that there exists considerable cross-national variation in oppositional behaviour during EAC deliberations in the six countries. The study finally shows that Eurosceptic parties are key drivers of opposition in EU affairs, especially when it comes to opposition directed at the EU political system.

description: Research on party responsiveness in established democracies suggests that parties follow shifts in the preferences of either the general electorate or party supporters. Drawing on theoretical models of party competition and research on party-voter congruence, we argue in this article that in the 21st century Western European mainstream parties respond to their partisan constituents. Parties adjust their policy positions to eliminate previous incongruence between themselves and their constituents and follow the shifts in supporters' positions. Analyses based on a series of datasets that use expert surveys and election surveys to measure parties' positions and several cross-national and national surveys to measure voters' preferences between 1999 and 2014 strongly support the argument that mainstream parties respond to existing incongruence. The findings in this article update many of the empirical results of prior studies on party responsiveness to public opinion shifts, with important ramifications for our understanding of party-based representation in contemporary European democracies.

EMVA 1288

description: We propose a novel multispectral imaging technique employing complementary notch filters instead of bandpass filters which are conventionally used in filter-based multispectral cameras. Therefore, only little power of the incoming photon signal is lost and thus the SNR of the multispectral data can be significantly improved. To validate the proposed approach, simulations of conventional bandpass filters as well as complementary notch filters are presented. To compare the resulting SNRs, the EMVA 1288 standard is adopted in such a way that it is applicable to notch filter-based multispectral cameras. It is found that the SNR can be significantly improved by using complementary filters instead of the conventional bandpass filters, especially at high spectral resolution.

description: This work aims at investigating the molecular gas component in the vicinity of two young stellar object (YSO) candidates identified at the border of the HII region G034.8-0.7 that is evolving within a molecular cloud shocked by the SNR W44. The purpose is to explore signatures of star forming activity in this complex region. We performed a near and mid infrared study towards the border of the HII region G034.8-0.7 and observed a 90" X 90" region near 18h 56m 48s, +01d 18' 45" (J2000) using the Atacama Submillimeter Telescope Experiment (ASTE) in the 12CO J=3--2, 13CO J=3--2, HCO+ J=4--3 and CS J=7--6 lines with an angular resolution of 22". Based on the infrared study we propose that the source 2MASS 18564827+0118471 (IR1 in this work) is a YSO candidate. We discovered a bipolar 12CO outflow in the direction of the line of sight and a HCO+ clump towards IR1, confirming that it is a YSO. From the detection of the CS J=7--6 line we infer the presence of high density (>10^7 cm^-3) and warm (>60 K) gas towards IR1, probably belonging to the protostellar envelope where the YSO is forming. We investigated the possible genetic connection of IR1 with the SNR and the HII region. By comparing the dynamical time of the outflows and the age of the SNR W44, we conclude that the possibility of the SNR has triggered the formation of IR1 is unlikely. On the other hand, we suggest that the expansion of the HII region G034.8-0.7 is responsible for the formation of IR1 through the "collect and collapse" process.

Use of the Cloze procedure in the assessment of schizophrenic thought disorder
Creators: name: Huberman, Jack Jacob
Publisher: name: University of British Columbia
Year: 2011

description: The present investigation was an attempt to determine the validity of the Cloze Procedure in assessing differences between schizophrenic patients in the relative severity of thought disorganization. For this purpose, samples of schizophrenic speech in response to TAT cards were obtained from twelve male schizophrenic patients who had been rank ordered by two psychiatrists in terms of disordered thought processes. Equal length schizophrenic language samples with every fifth word deleted and replaced by a standard length blank were mimeographed and presented to a group of upper level undergraduate psychology students who were instructed to try to guess the missing words from the context of those that remained. These mutilated language samples constitute the Cloze forms. The scores on the Cloze Procedure represented a rank ordering by the students of the severity of schizophrenic thought disturbance in terms of the number of correctly replaced words in the language samples elicited from each patient. A substantial correlation coefficient ("r" = .82) was found between the rank order on the Cloze Procedure and the rank order obtained in the external criterion measure, that is, the psychiatric ratings. The results of tests for internal consistency and reliability of the Cloze Procedure ("W" = .622) and for the reliability of the Close raters ("R" = .792) were also substantial. A number of advantages and disadvantages of this method of investigation are discussed and contrasted with those of other somewhat similar procedures. Possible applications to psychiatric research are suggested. The results appear to be conclusive within the limitations of the criterion measure employed in this study. More widespread generalizations await further research which is invited in light of the apparently promising findings of this exploratory study.

description: The theory of Minimal Surfaces has developed rapidly in the past 10 years. There are many factors that have contributed to this development: Sophisticated construction methods [14,29,31] have been developed and have supplied us with a wealth of examples which have provided intuition and spawned conjectures. Deep curvature estimates by Colding and Minicozzi [3] give control on the local and global behavior of minimal surfaces in an unprecedented way. Much progress has been made in classifying minimal surfaces of ﬁnite topology or low genus in ℝ3 or in other ﬂat 3-manifolds. For instance, all properly embedded minimal surfaces of genus 0 in ℝ3, even those with an inﬁnite number of ends, are now known [21, 23, 25]. There are still numerous diﬃcult but easy to state open conjectures, like the genus-g helicoid conjecture: There exists a unique complete embedded minimal surface with one end and genus g for each g ∈ N, or the related Hoffman–Meeks conjecture: A ﬁnite topology surface with genus g and n ≥ 2 ends embeds minimally in ℝ3 with a complete metric if and only if n ≤ g + 2. Sophisticated tools from 3-manifold theory have been applied and generalized to understand the geometric and topological properties of properly embedded minimal surfaces in ℝ3. Minimal surfaces have had important applications in topology and play a prominent role in the larger context of geometric analysis.
Scaling forces to asteroid surfaces: The role of cohesion

description: The scaling of physical forces to the extremely low ambient gravitational acceleration regimes found on the surfaces of small asteroids is performed. Resulting from this, it is found that van der Waals cohesive forces between regolith grains on asteroid surfaces should be a dominant force and compete with particle weights and be greater, in general, than electrostatic and solar radiation pressure forces. Based on this scaling, we interpret previous experiments performed on cohesive powders in the terrestrial environment as being relevant for the understanding of processes on asteroid surfaces. The implications of these terrestrial experiments for interpreting observations of asteroid surfaces and macro-porosity are considered, and yield interpretations that differ from previously assumed processes for these environments. Based on this understanding, we propose a new model for the end state of small, rapidly rotating asteroids which allows them to be comprised of relatively fine regolith grains held together by van der Waals cohesive forces.

Sovereignty as a constitutional issue in Imperial Russia, 1905-1915.
Creators: name: Hutchinson, John F
Publisher: name: University of British Columbia
Year: 2011

description: The turbulent reign of Tsar Nicholas II has been treated by many historians, but few of them have delved deeply into the important constitutional issues which arose during the crucial years 1905-1915. Undoubtedly, the most important constitutional problem of the period was the exercise of sovereignty. Where did sovereignty reside in theory, and who exercised it in practice? Was the Tsar the sovereign power, or was sovereignty exercised on his behalf by someone else? Could the Tsar have become a constitutional monarch by limiting his own sovereign powers? Did the October Manifesto establish a constitutional monarchy, and if not, what was its real significance? These are some of the most important questions which are discussed in detail in the thesis. The political events of the decade are examined in the light of the constitutional problems raised in 1905. The evidence presented suggests that the importance of the October Manifesto as a constitutional document has been exaggerated, and that the Fundamental Laws of 1906 were far more significant than has been generally believed. Count Witte's role in preserving the imperial prerogative powers is analysed in some detail. It is argued that the Fundamental Laws left the Emperor's legislative prerogative intact, and that the Duma therefore lost its raison d'être long before its first convocation. This loss caused the first two Dumas to challenge the constitutional system established by the Fundamental Laws. The Third Duma achieved a kind of pragmatic authority during the Stolypin regime, but after 1911 the Duma ceased to play any kind of effective role in the governing process. Finally, it is argued that Nicholas II was incapable of exercising intelligently the extensive prerogative powers which the Emperor retained after 1905. His deficiencies of character and his reactionary political ideas made it impossible for reasonable men to serve as his ministers. In August of 1915, the worsening military situation necessitated an unequivocal decision by the Tsar as to whether he would accept once and for all the establishment of a constitutional monarchy. From the course of the negotiations between the Progressive Bloc and the cabinet, it would appear that a final transfer of the imperial legislative prerogative to the Duma was not contemplated; rather, the legislative prerogative would be exercised by a ministry of public and military leaders on behalf of the Emperor. This Nicholas could not bring himself to accept. He chose to rule rather than reign, and ruled as a virtually absolute monarch until 1917, when he suddenly found he had no choice at all but to abdicate.

description: Echoes of Time: an exploration of photography, land, and memories is an art-based research project that investigates how photography can be employed to examine the relationship between land and memory. The artistic output of this research reflects a personal experimental documentation of a meaning of place, the local, the home, and the imagined through the lens of memory and belonging. Belonging, attachment to place, and family connections have been the conduits to encounter, interrogate, and engage through various photographic practices. The use of different visual representations explores attachment and engagement with place and allowed the creative element of this research to be the voice for these research methodologies, culminating in a trilogy of hand-made books. The investigation is elaborated in the form of three nodes. Each has been given a unique title that contextualises a sub-theme within the research. • The first node, Hinterland relates to the parish where I live; a place where my paternal family have lived for over three hundred years. This node investigates the parish boundary, thus considering the locality through photographic mapping referencing Yi Fu Tuan. Tuan’s approach focuses on how place becomes a small world of personal experience. • The second node, Wryttún considers the boundary of the home, which has been in my family for three generations. The footprint of my garden is investigated as a place of belonging and attachment through its materiality referencing Edward Relph. This considers how Relph’s concept of attachment is interrogated through the materiality of the garden as a form of mapping place. • The final node, Hiraeth explores the influence of memories of place creating imagined landscapes through constructed images referencing Roland Barthes. Whereas Barthes used photography to search for memories, this work seeks to use memories of place to create images of former lived experiences. This research contributes to existing knowledge by creating an artistic autobiographical account of the ways in which family lineage and connection enhance meanings of place. A substantial period of this Doctoral Research was carried out during the 2020-2022 Covid Pandemic and, although is not specifically related to the research questions, was significantly influenced and limited by the number and length of national lockdowns.

description: Mathematical relativity, the subject of this conference, has recently become more and more devoted to the theory of nonlinear evolution equations, with global questions becoming ever more accessible. This is reﬂected by the fact that more than half of the talks given were concerned with the global dynamics of solutions of evolution equations related more or less directly to the Einstein equations of general relativity. Progress was reported in understanding subjects such as black holes, gravitational radiation, cosmology and the relation of general relativity to Newtonian gravitational theory.

description: It is known that there is no three-dimensional analog of de Sitter black holes. I show that the analog does exist when non-Gaussian (i.e., ring-type) smearings of point matter hairs are considered. This provides a new way of constructing black hole solutions from hairs. I find that the obtained black hole solutions are quite different from the usual large black holes in that there are i) large to small black hole transitions which may be considered as inverse Hawking-Page transitions and ii) soliton-like (i.e., non-perturbative) behaviors. For Gaussian smearing, there is no black hole but a gravastar solution exists.

description: The conference aimed to discuss the nature of mathematical language with the focus set on the history of mathematical symbolism and symbolisation in a wide sense. Its contents were arranged along three main topics—symbolization from Mesopotamian, Egyptian, Greek, Latin, Indian and Chinese perspectives; algebraic analysis and symbolization in Europe, 1500–1750; the 19th and 20th century. The intention was to deal with the topic extensively, including all kinds of symbolism shaped in various traditions. Major problems addressed by the conference include but are not limited to why speciﬁc notations and symbolisms were introduced, how they were designed and how they were used. In addition, the lectures also dealt with the attitudes towards, and reﬂections on, mathematics and language that their introduction stirred. We hope that the workshop will contribute to shape future research in this domain.
A comparison of the static and dynamic properties of a semi-flexible polymer using lattice-Boltzmann and Brownian dynamics simulations

description: The aim of this paper is to compare results from lattice-Boltzmann and Brownian dynamics simulations of linear chain molecules. We have systematically varied the parameters that may affect the accuracy of the lattice-Boltzmann simulations, including grid resolution, temperature, polymer mass, and fluid viscosity. The effects of the periodic boundary conditions are minimized by an analytic correction for the different long-range interactions in periodic and unbounded systems. Lattice-Boltzmann results for the diffusion coefficient and Rouse mode relaxation times were found to be insensitive to temperature, which suggests that effects of hydrodynamic retardation are small. By increasing the resolution of the lattice-Boltzmann grid with respect to the polymer size, convergent results for the diffusion coefficient and relaxation times were obtained; these results agree with Brownian dynamics to within 1--2%.

description: This workshop gathered 45 participants from 16 countries and had a correspondingly multifaceted program covering various infectious diseases, public health applications, and methodological innovations. The discussions and presentations focused on the importance of mathematical models and statistical analyses in understanding the complex transmission systems of infectious diseases and in planning eﬀective intervention strategies. Many diﬀerent statistical and mathematical approaches were covered. The general unifying theme is that the analyses and models take into account the underlying transmission of the infectious agent among the hosts and/ or vector populations.

description: We investigate an alternative to the Sequential Propagator Method used in Lattice QCD calculations of semileptonic form factors. We replace the sequential propagator with a stochastic propagator so that, in principle, all momentum and sink smearing combinations are available with only a single spin-color inversion. Practically, the stochastic noise is significant and must be reduced at the cost of more inversions. We study the behavior of the stochastic noise and compare the computational costs of this stochastic technique and the Sequential Propagator Method. We also present preliminary semileptonic form factor results using the stochastic technique on N_f=2 configurations with a non-perturbatively improved Sheikoleslami-Wohlert action generated by the QCDSF collaboration. At a fixed cost, measured in terms of the number of heavy-quark inversions, the method provides more correlators for the extraction of the form factors at various q^2's than the Sequential Propagator Method. These additional correlators reduce the total statistical errors of certain kinematic points, although the stochastic error is still comparable to the gauge error at other points.

description: We measured magnetotransport properties of PbS single crystals which exhibit the quantum linear magnetoresistance (MR) as well as the static skin effect that creates a surface layer of additional conductivity. The Shubnikov-de Haas oscillations in the longitudinal MR signify the peculiar role of spin-orbit coupling. In the angular-dependent MR, sharp peaks are observed when the magnetic field is slightly inclined from the longitudinal configuration, which is totally unexpected for a system with nearly spherical Fermi surface and points to an intricate interplay between the spin-orbit coupling and the conducting surface layer in the quantum transport regime.

description: In the European context, the Commission is responsible for monitoring and enforcing states’ compliance with EU legislation. However, the Commission often entrusts external actors to monitor and assess implementation. To what extent does the Commission withhold, partially or fully disclose compliance assessments? Drawing on reputational accounts of bureaucratic performance, it is expected that the Commission is confronted with competing incentives. On the one hand, the Commission needs to justify enforcement decisions based on expert evaluations. On the other hand, disseminating information about non-compliance could exacerbate relations with the member states and threatens to damage the Commission’s unique reputation as the main guardian of the EU treaties. Employing a novel data-set on the transparency of compliance assessments, it is found that the Commission discloses compliance assessments prepared by highly competent external actors only partially. The finding raises concerns about the extent to which wider audiences are sufficiently informed about national implementation outcomes.

description: Do governments represent the material needs and preferences of their voters? This is one of the central questions of political science with great consequences for how we should evaluate the state of democracy. A thorough test of the link between voters’ economic vulnerabilities and public policies is presented in the article. Using data covering 17 European democracies, it is shown empirically that economically vulnerable voters support generous unemployment protection; that parties adopt policy positions that correspond with these voter signals; that entire party systems can meaningfully be described by the economic vulnerabilities of parties’ voters; and that parties, when entering office, pursue policies aligned with their voters’ needs and preferences.

description: AMiBA is the largest hexapod astronomical telescope in current operation. We present a description of this novel hexapod mount with its main mechanical components -- the support cone, universal joints, jack screws, and platform -- and outline the control system with the pointing model and the operating modes that are supported. The AMiBA hexapod mount performance is verified based on optical pointing tests and platform photogrammetry measurements. The photogrammetry results show that the deformations in the inner part of the platform are less than 120 micron rms. This is negligible for optical pointing corrections, radio alignment and radio phase errors for the currently operational 7-element compact configuration. The optical pointing error in azimuth and elevation is successively reduced by a series of corrections to about 0.4 arcmin rms which meets our goal for the 7-element target specifications.

description: Policy inquiry commissions are widely used in policy-preparation processes across Europe and beyond. While previous research has primarily focussed on commissions as expert bodies and corporatist arrangements, this study investigates whether political factors affect a political incumbent's decision to establish commissions. The hypothesis is that incumbent parties are more likely to appoint commissions under certain political conditions – i.e. depending on parliamentary strength, government colour and government composition – and when certain policy issues are salient on the policy agenda of the government and the opposition. The study uses a novel dataset that combines more than 2000 commission appointments in Norway and Denmark between 1971 and 2017 with party manifesto and electoral study data to test the expectations. The agenda perspective is partly sustained, and the study shows that minority governments, left-leaning governments, and coalition governments appoint commissions more extensively than their counterparts, although the results differ slightly in the two countries.

We show that if k is a perfect field or a local field, then such a BN-pair must be virtually trivial. We also consider arbitrary compact groups and show that the only abstract BN-pairs they can admit are spherical, and even virtually trivial provided they are split.

Mini-Workshop: Formal Methods in Commutative Algebra: A View Toward Constructive Homological Algebra
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2009
Subjects: subject: Konferenzschrift
subject: 510

description: The purpose of the mini-workshop is to bring into the same place diﬀerent mathematical communities that study constructive homological algebra and are motivated by diﬀerent applications (e.g., constructive algebra, symbolic computation, proof theory, algebraic topology, mathematical systems theory, D-modules, dynamical systems theory) so that they can share their results, techniques, softwares and experiences. Through the development of a uniﬁed terminology, common mathematical problems, which naturally appear when making homological algebra constructive, were discussed.

description: In May 2003, the State, Society and Governance in Melanesia Project and the Centre for Conflict & Post-Conflict Studies Asia-Pacific hosted the Southern Highlands Province Workshop at the Australian National University. The workshop explored key issues in the Southern Highlands, the nature of conflict, the prospects for conflict transformation, and the possible roles for donors in conflict and post-conflict situations. This discussion paper by Laurence Goldman focuses on the Huli, their reasons for engaging in conflict and their strategies for conflict resolution.

description: We developed a method to make GEM foils with a spherical geometry. Tests of this procedure and with the resulting spherical \textsc{gem}s are presented. Together with a spherical drift electrode, a spherical conversion gap can be formed. This would eliminate the parallax error for detection of x-rays, neutrons or UV photons when a gaseous converter is used. This parallax error limits the spatial resolution at wide scattering angles. The method is inexpensive and flexible towards possible changes in the design. We show advanced plans to make a prototype of an entirely spherical triple-GEM detector, including a spherical readout structure. This detector will have a superior position resolution, also at wide angles, and a high rate capability. A completely spherical gaseous detector has never been made before.

description: This series of papers explores the evolution of late-type galaxies in the rich cluster Abell 85. Here, we revisit the complex dynamical state of A 85 by using independent methods. We analyze the redshift distribution towards the cluster out to 40,000 km/s, and determine the mean redshifts of the background clusters A 87 and A 89. We then search for substructures in A 85 by considering the 2-D galaxy distribution for its members and by applying the kinematical 3-D Delta-test to both projected positions and radial velocities. This clearly reveals several substructures that we describe. We also analyse the distribution of the brightest blue galaxies across a major fraction of the cluster volume, considering if they are gas-rich or poor. We report a very asymmetric distribution of the blue member galaxies, and connect it with substructures revealed in the optical and X-rays. By matching our sample of bright blue member galaxies with HI detections reported in the literature, we identify gas-rich and gas-poor ones. HI-rich blue galaxies also turn out to be asymmetrically distributed, with most of them projected on the eastern side of the cluster. No blue objects have been detected in HI up to a projected radius of 2 Mpc in this zone. We estimate the ram pressure stripping exerted by the intra-cluster medium as a function of the projected distance from A 85, and quantify how important this mechanism may be in sweeping the gas out of the infalling spirals.

description: A parallel scalable Data Acquisition System, based on VME, has been developed to be used in the FINUDA experiment, scheduled to run at the DAFNE machine at Frascati starting from 1997. The acquisition software runs on embedded RTPC 8067 processors using the LynxOS operating system. The readout of event fragments is coordinated by suitable trigger Supervisor. Data read by different controllers are transported via dedicated bus to a Global Event Builder running on a UNIX machine. Commands from and to VME processors are sent via socket based network protocols. The network hardware is presently ethernet, but it can easily changed to optical fiber.

Year: 2009
Subjects: subject: Konferenzschrift
subject: 510

description: This workshop presented recent advances in ﬁne structure and inner model theory. There were extended tutorials on hod mice and the Mouse Set Conjecture, suitable extender sequences and their ﬁne structure, and the construction of true K below a Woodin cardinal in ZFC. The remaining talks involved precipitous ideals, stationary set reﬂection, failure of SCH in ZF, nonthreadable square sequences, reverse mathematics, forcing axioms, covering properties of canonical inner models, and “set theoretic geology.”
Probing recent star formation with absorption-line strengths in hierarchical models and observations

description: Stellar population parameters derived from spectral line-strengths provide a powerful probe of galaxy properties and formation histories. We implement the machinery for extracting single-stellar-population-equivalent stellar population parameters from synthetic spectra generated by a hierarchical galaxy formation model. We find that the SSP-equivalent age is related to the light-weighted age in a complicated fashion that reflects the influence of recently-formed stars and is poorly correlated with the mass-weighted age. The tendency for SSP-equivalent ages to be biased young means that archaeological downsizing overstates the mass-weighted downsizing in age with mass. We find that the SSP-equivalent metallicity closely tracks the mass- and light-weighted metallicities, so that observed mass--metallicity relations for old galaxies closely reflect the underlying trends. We construct mock catalogues of early-type galaxies in a Coma cluster-sized halo and compare them directly to observations of early-type galaxies in the Coma cluster. The similarity of the SSP-equivalent ages in the observational samples and the mock catalogues gives us confidence that the star-formation quenching implemented in the hierarchical galaxy formation model produces roughly the correct amount of recent star formation. The SSP-equivalent metallicities are however too low and have the wrong slope as a function of velocity dispersion, and the SSP-equivalent ages of the model galaxies may have an incorrect slope as a function of velocity dispersion.

description: Computational Complexity Theory is the mathematical study of the intrinsic power and limitations of computational resources like time, space, or randomness. The current workshop focused on recent developments in various sub-areas including arithmetic complexity, Boolean complexity, communication complexity, cryptography, probabilistic proof systems, pseudorandomness, and quantum computation. Many of the developements are related to diverse mathematical ﬁelds such as algebraic geometry, combinatorial number theory, probability theory, quantum mechanics, representation theory, and the theory of error-correcting codes.
Three dimensional N=4 supersymmetric mechanics with Wu-Yang monopole

description: We propose Lagrangian and Hamiltonian formulations of a N=4 supersymmetric three-dimensional isospin-carrying particle moving in the non-Abelian field of a Wu-Yang monopole and in some specific scalar potential. This additional potential is completely fixed by N=4 supersymmetry and in the simplest case of flat metrics it coincides with that which provides the existence of the Runge-Lenz vector for the bosonic subsector. The isospin degrees of freedom are described on the Lagrangian level by bosonic auxiliary variables forming N=4 supermultiplet with additional, also auxiliary fermions. Being quite general, the constructed systems include such interesting cases as N=4 superconformally invariant systems with Wu-Yang monopole, the particles living in the flat R^3 and in the R x S^2 spaces and interacting with the monopole, and also the particles moving on three-dimensional sphere and pseudo-sphere with Wu-Yang monopole sitting in the center. The superfield Lagrangian description of these systems is so simple that one could wonder to see how all couplings and the proper coefficients arise while passing to the component action.

description: Lattice dynamical methods used to predict phase-transformations in crystals typically evaluate the harmonic phonon spectra and therefore do not work in frequent and important situations where the crystal structure is unstable in the harmonic approximation, such as the $β$ structure when it appears as a high-temperature phase of the shape memory alloy (SMA) NiTi. Here it is shown by self consistent {\it ab initio} lattice dynamical calculations (SCAILD) that the critical temperature for the pre-martensitic $R$ to $β$ phase-transformation in NiTi can be effectively calculated with good accuracy, and that the $β$-phase is a result primarily of the stabilizing interaction between different lattice vibrations.
