description: We show that three SU(2) singlet neutral scalars (two CP-even and one CP-odd) in the spectrum of models based on the gauge symmetry SU(3)_c X SU(3)_L X U(1)_X, which do not contain exotic electric charges, are realistic candidates for thermally generated self-interacting dark matter in the Universe, a type of dark matter that has been recently proposed in order to overcome some difficulties of collisionless cold dark matter models at the galactic scale. These candidates arise without introducing a new mass scale in the model and/or without the need for a discrete symmetry to stabilize them, but at the expense of tuning several combinations of parameters of the scalar potential.

description: A central prospect of antiferromagnetic spintronics is to exploit magnetic properties that are unavailable with ferromagnets. However, this poses the challenge of accessing such properties for readout and control. To this end, light-induced manipulation of the transient ground state, e.g. by changing the magnetic anisotropy potential, opens promising pathways towards ultrafast deterministic control of antiferromagnetism. Here, we use this approach to trigger a $\it{coherent}$ rotation of the entire long-range antiferromagnetic spin arrangement about a crystalline axis in $GdRh_2Si_2$ and demonstrate $\it{deterministic}$ control of this rotation upon ultrafast optical excitation. Our observations can be explained by a displacive excitation of the Gd spins$'$ local anisotropy potential by the optical excitation, allowing for a full description of this transient magnetic anisotropy potential.

Der Ablauf der Letzten Vereisung und der Postglazialzeit in Neuseeland war nach den vorliegenden C14-Bestimmungen genau gleichzeitig mit dem der Nordhalbkugel. War aber die Letzte Eiszeit auf beiden Halbkugeln gleichzeitig, dann müssen es auch die früheren gewesen sein. Das stimmt mit der MILANKOVITCH-Kurve nicht überein. Diese kann in der vorliegenden Form nicht als Ursache der Eiszeiten herangezogen werden.

description: We study the Dirichlet problem for an elliptic equation involving the $1$-Laplace operator and a reaction term, namely: $$ \left\{\begin{array}{ll} \displaystyle -Δ_1 u =h(u)f(x)&\hbox{in }Ω\,,\\ u=0&\hbox{on }\partialΩ\,, \end{array}\right. $$ where $ Ω\subset \mathbb{R}^N$ is an open bounded set having Lipschitz boundary, $f\in L^1(Ω)$ is nonnegative, and $h$ is a continuous real function that may possibly blow up at zero. We investigate optimal ranges for the data in order to obtain existence, nonexistence and (whenever expected) uniqueness of nonnegative solutions.

description: We present the design, fabrication, and response of a low-power, polymer-based VOC sensor based on the self-leveling of mechanically leveraged structures. The device utilizes folded polymer-coated microcantilevers to achieve passive temperature compensation without the need for additional compensating sensors or electronics. We demonstrate that a self-leveling vapor sensor provides the same gas response as a simple microcantilever geometry, showing ~20% change in device capacitance when subjected to 35-85 %RH change while showing nearly-zero baseline drift due to changes in ambient temperature when the temperature is increased from 23-72°C which is ~52-fold better than a simple microcantilever geometry. The response of the VOC sensor was measured using three polymers (Polyimide, Polyurethane, and PDMS) against five different analytes (Ethanol, Acetone, Benzene, Hexane, and Water) and an SVM-based model was used to show target specificity. The sensor also showed an absorption response time (τ90) of ~138s. We propose that the self-leveling vapor sensor geometry is a significant improvement to a simple microcantilever vapor sensor as it offers the same performance but shows near-complete elimination of temperature-induced baseline drift.

description: Many concepts of Fourier analysis on Euclidean spaces rely on the specification of a frequency point. For example classical Littlewood Paley theory decomposes the spectrum of functions into annuli centered at the origin. In the presence of structures which are invariant under translation of the spectrum (modulation) these concepts need to be refined. This was first done by L. Carleson in his proof of almost everywhere convergence of Fourier series in 1966. The work of M. Lacey and the author in the 1990's on the bilinear Hilbert transform, a prototype of a modulation invariant singular integral, has revitalized the theme. It is now subject of active research which will be surveyed in the lecture. Most of the recent related work by the author is joint with C. Muscalu and T. Tao.

description: Turbulence is ever produced in the low-viscosity/large-scale fluid flows by the velocity shears and, in unstable stratification, by buoyancy forces. It is commonly believed that both mechanisms produce the same type of chaotic motions, namely, the eddies breaking down into smaller ones and producing direct cascade of turbulent kinetic energy and other properties from large to small scales towards viscous dissipation. The conventional theory based on this vision yields a plausible picture of vertical mixing and remains in use since the middle of the 20th century in spite of increasing evidence of the fallacy of almost all other predictions. This paper reveals that in fact buoyancy produces chaotic vertical plumes, merging into larger ones and producing an inverse cascade towards their conversion into the self-organized regular motions. Herein, the velocity shears produce usual eddies spreading in all directions and making the direct cascade. This new paradigm is demonstrated and proved empirically; so, the paper launches a comprehensive revision of the theory of unstably stratified turbulence and its numerous geophysical or astrophysical applications.

Creators: name: Romeo, Margherita
Publisher: name: The Open University

description: Immunoglobulin light chain amyloidosis (AL) is the most common form of systemic amyloidosis in which a plasma-cell dyscrasia results in the overproduction of amyloidogenic immunoglobulin light chains (LC). Although LC organize in extracellular deposits in different target organs, approximately 75% of patients manifest heart involvement at presentation, with a median survival of only 6 months if chemotherapy fails to stop LC production. Although an active role of radical oxygen species (ROS) has already been envisaged, the actual mechanisms behind their generation remain elusive.

 In this study, it was observed that amyloidogenic LC purified from patients with cardiac involvement intrinsically generated high levels of ROS and, when administered to C. elegans resulted in ROS production. These species can directly target the pharyngeal cells, causing remarkable damage particularly at the mitochondrial level, similar to that observed in amyloid-affected hearts from AL patients. Tetracycline counteracted all these ROS-mediated effects and, when added to standard chemotherapy, they reduced early deaths in patients with cardiac AL. To limit and repair the stress-induced damage, different intracellular signalling events are activated. In particular, the nuclear translocation of the FOXO/DAF-16 transcription factor triggers the transcription of stress-responsive genes, including heat-shock protein (hsp)-16.2 and manganese superoxide dismutase (sod)-3, and controlling stress resistance and survival.

 All these effects were entirely dependent on the presence of metal ions, particularly copper. Metal chelators or metal-binding compounds, particularly the new drug PBT2, block ROS production and interrupt the vicious cycle of oxidative stress. In C. elegans, low doses of PBT2 in combination with tetracycline result in a synergistic beneficial effect, highlighting the potential application of this pharmacological strategy for AL patients. These findings indicate that metal-induced oxidative stress, already reported to be linked with some neurological disorders, is also a key element in cardiac AL amyloidosis.

description: Sowohl im Tal des Regen nächst seiner Einmündung in die Donau bei Regensburg wie im unteren Maintal bei Marktheidenfeld sind mächtige altquartäre Talverschüttungen aufgeschlossen. Sie lassen sich jeweils in eine ältere Akkumulationsphase, eine nachfolgende Auephase und in eine abschließende jüngere Akkumulationsphase aufgliedern. Einer im Maintal nachfolgenden Erosionsperiode entspricht bei Regensburg ein extremer Pseudogley. Darüber folgen Gehängeablagerungen und schließlich Löß unterschiedlicher Fazies mit drei zwischengeschalteten interglazialen Parabraunerden. Damit liegt in beiden Talsystemen die große Verschüttungsperiode vor der viertletzten Eiszeit. Auch die der Jüngeren Steppenzeit zugeordnete Säugetierfauna von Randersacker gehört in die (jüngere?) Verschüttungsphase. Die Ursache der offensichtlich nicht allein auf das untere Main-und Neckartal beschränkten Talverschüttung wird in einer allgemeinen Hebungstendenz der Mittelgebirge vor der Günzeiszeit vermutet.

description: A rapid decrease in the critical current density (Jc) of YBa2Cu3O7-x (YBCO) films with increasing film thickness has been observed for multiple YBCO growth processes. While such behavior is predicted from 2D collective pinning models under certain assumptions, empirical observations of the thickness dependence of Jc are believed to be largely processing dependent at present. To investigate this behavior in ex situ YBCO films, 2.0 and 2.9 um thick YBCO films on ion beam assisted deposition (IBAD) - yttria stabilized zirconia (YSZ) substrates were thinned and repeatedly measured for rho(T) and Jc(H). The 2.9 um film exhibited a constant Jc(77K,SF) through thickness of ~1 MA/cm2 while the 2.0 um film exhibited an increase in Jc(77K,SF) as it was thinned. Neither film offered evidence of significant dead layers, suggesting that further increases in critical current can be obtained by growing thicker YBCO layers.

title: Advances in the Contour Method for Residual Stress Measurement
Creators: name: Achouri, Anas
Publisher: name: The Open University
Year: 2018

description: The aim of this PhD thesis is to extend the capability of the contour method for residual stress measurement in metallic components by resolving two of its main limitations. The contour method involves sectioning a body into two equal parts that have mirror-symmetric geometry, stiffness and residual stress field. The deformations of the cut surfaces introduced by sectioning are then measured. These raw measured data are processed using filtering and smoothing techniques. The last step involves back calculating the residual stress distribution acting out of the cut plane that has been relaxed. This is equal to the original residual stress present at the cut plane before the body was cut. A major limitation of the contour technique is that it is strictly only applicable to flat cuts along a symmetry plane of a body. Another fundamental assumption in the contour method is that residual stresses re-distribute elastically during the sectioning cut. However, this assumption can be violated if the residual stress magnitude is close to the material yield strength value and lead to plasticity cutting induced errors in the contour method results. Thus another major limitation of the technique is the risk of cutting induced plasticity that can introduce significant stress measurement errors. This PhD thesis contributes to knowledge in the field through first presenting a novel contour data analysis approach for the more general case of sectioning at an arbitrary plane where the cut parts do not possess mirror-symmetry. This greatly extends the types of structure, and the volume of material within structures, where residual stresses can be measured using the contour method. The second contribution to knowledge is the invention of an incremental contour measurement method involving multiple cuts. This new approach can be applied to sequentially reduce residual stresses in the structure of interest and thereby lower or eliminate the risk of inducing plasticity during cutting and reduce consequent measurement errors. Both new approaches proposed in this PhD thesis are successfully demonstrated through numerical simulation using the finite element method and experimentally on benchmark steel specimens and against neutron diffraction measurements.

title: Sparse Linear Discriminant Analysis with more Variables than Observations

Publisher: name: The Open University
Year: 2018

description: It is known that classical linear discriminant analysis (LDA) performs classification well when the number of observations is much larger than the number of variables. However, when the number of variables is larger than the number of observations, classical LDA cannot be performed because the within-group covariance matrix is singular. Recently proposed LDA methods that can handle singular within-group covariance matrix were reviewed. Most of these methods focus on regularizing the within-class covariance matrix. However, they give less attention to sparsity ( selecting variables), interpretation and computational cost, which are important in high-dimensional problems. The fact that most of the original variables may be irrelevant or redundant suggests looking for sparse solutions that involve only a small portion of the variables. In the present work, new sparse LDA methods are proposed that are suited to high-dimensional data. The first two methods assume groups share a common within-group covariance matrix and approximate this matrix by a diagonal matrix. One of these methods is a variant of the other that sacrifices some accuracy for greater computational speed. Both methods obtain sparsity by minimizing an l1 norm and maximizing discrimination power under a common loss function with a tuning parameter. The third method assumes that groups share common eigenvector in eigenvector-eigenvalue decomposition of their within-group covariance matrices, while their eigenvalues may differ. The fourth method assumes the within-group covariance matrices are proportional to each other. The fifth method is derived from the Dantzig selector and uses optimal scoring to construct discriminant function. The third and fourth methods achieve sparsity by imposing a cardinality constraint with the cardinality level determined by cross-validation. All the new methods reduce their computation time by sequentially determining individual discriminant functions. The methods are applied to six real data sets and perform well when compared with two existing methods.
title: Restoration of the Long-spined Sea Urchin, Diadema antillarum, to Caribbean Coral Reefs
Creators: name: Bodmer, Max David Vincent
Publisher: name: The Open University
Year: 2019

description: Coral reefs are among the most valuable and threatened ecosystems on Earth. Lower species diversity, and subsequently reduced resilience, make Caribbean reefs especially vulnerable to anthropogenic stressors. Overfishing and disease have reduced Caribbean herbivore abundances and their associated compensatory dynamics, leading to a 53% decrease in scleractinian coral cover since the 1970s. The long-spined sea urchin, Diadema antillarum, is an important Caribbean herbivore, and its functional extinction in the early 1980s, coupled with a subsequent lack of recovery, makes its restoration a conservation priority. A combination of in situ ecological surveys and environmental manipulations are coupled with ex situ experimental studies to aid D. antillarum restoration efforts. The thesis begins by assessing the relative impacts of fish and urchin grazing on the structure and diversity of reef communities and concludes that, whilst reestablishment of D. antillarum ecosystem functions may not represent a long-term conservation solution, it will provide short-term resilience benefits. A lab-based investigation then indicates that D. antillarum will be, at least partially, resistant to predicted future sea surface temperature increases, and observed negative fitness consequences may be mitigated by artificial structures; population restoration is therefore worthwhile in the context of climate change. Exploration of an isolated population boom then identifies a dearth of predation refugia, created by region-wide reef flattening, as the major barrier to recovery, and deployment of experimental artificial reefs demonstrates that augmentation of reef complexity is a viable strategy for increasing population size and reversing phase shifts. Restoration of D. antillarum will undoubtedly contribute to long-term ecosystem persistence, and insights contained within this thesis may help facilitate the difficult transition of Caribbean coral reefs to their future stable state.

description: We present a stochastic lattice theory describing the kinetic behavior of trapping reactions $A + B \to B$, in which both the $A$ and $B$ particles perform an independent stochastic motion on a regular hypercubic lattice. Upon an encounter of an $A$ particle with any of the $B$ particles, $A$ is annihilated with a finite probability; finite reaction rate is taken into account by introducing a set of two-state random variables - "gates", imposed on each $B$ particle, such that an open (closed) gate corresponds to a reactive (passive) state. We evaluate here a formal expression describing the time evolution of the $A$ particle survival probability, which generalizes our previous results. We prove that for quite a general class of random motion of the species involved in the reaction process, for infinite or finite number of traps, and for any time $t$, the $A$ particle survival probability is always larger in case when $A$ stays immobile, than in situations when it moves.

The decay amplitudes for the different phi K^{*0} helicity states are measured from the angular distributions of final state particles in the transversity basis. The longitudinal and transverse complex amplitudes are |A_0|^2 = 0.43 +- 0.09 +- 0.04, |A_perp|^2 = 0.41 +- 0.10 +- 0.04, arg(A_parallel) = -2.57 +- 0.39 +- 0.09, and arg(A_perp) = 0.48 +- 0.32 +- 0.06. The direct CP-violating asymmetries are found to be consistent with zero.

description: The food processing industries have recently experienced significant structural and economic performance changes, which have in turn had important impacts on the food system overall. In this paper I examine the cost structure of the 3- and 4-digit SIC level meat product industries in the U.S. and Australia from 1970-91. Further, I incorporate a demand structure to allow for trade and technological impacts on output demand and pricing. I evaluate scale, technological, trade, capital adjustment and markup effects using short and long run input cost and input and output demand elasticities. I find that input cost and composition patterns in the meat product industries indicate surprisingly consistent cost and demand structures across the industries and countries. 1he most important technological impacts seem to stem from significant scale economies, which involve capital investment and materials saving in the long run. Import competition appears further to motivate capital expansion. Although the tendency over time independently of these tech/ trade factors is to increase materials use, on balance these factors motivate capital deepening and materials and labor saving. Finally, although large markups of price over marginal cost are found, they are consistent with small markups over average costs (and thus profitability) due to the substantial underlying scale economies.

description: We examine whether an appreciable value of the lepton flavor mixing angle $θ_{13}$ at the electroweak scale $Λ_{\rm EW}$ can be radiatively generated from $θ_{13} = 0^\circ$ at the GUT scale $Λ_{\rm GUT}$. It is found that the renormalization-group running and seesaw threshold effects may lead to $θ_{13} \sim 5^\circ$ at low energies for two simple large-maximal mixing patterns of the MNS matrix in the minimal supersymmetric standard model. If $θ_{12}$ is sufficiently large at $Λ_{\rm GUT}$, it will be possible to radiatively produce $θ_{13} \sim 5^\circ$ at $Λ_{\rm EW}$ both in the standard model and in its supersymmetric extensions. The mass spectrum of three heavy right-handed Majorana neutrinos and the cosmological baryon number asymmetry via leptogenesis are also calculated.

title: Spirituality in the Music of Edmund Rubbra
Creators: name: Cradduck, Lucinda
Publisher: name: The Open University
Year: 2021

description: Edmund Rubbra’s music has frequently been described as spiritual, religious, contemplative or mystical by commentators, usually linking such descriptions to his mid-life conversion to Roman Catholicism and to his interest in Eastern thought. The title of this thesis sums up these qualities under the label ‘spirituality’, a term chosen deliberately for its potential to embrace a range of meanings. The aim of the thesis is twofold: to examine the various strands in Rubbra’s life that contribute to his spirituality, positioning them both biographically and within the context of contemporaneous English culture; and to show, through detailed analysis coupled with an interpretative stance, how these aspects of his spirituality are reflected in his music. The study is structured thematically, chapters dealing in turn with Rubbra’s youthful involvement with Theosophy; his work with dancers during the early years of his career, which can be shown to have a spiritual dimension; his lifelong interest in Eastern religions and philosophies; and his spiritual response to nature. The final two chapters consider two themes with a more Christian emphasis: Rubbra’s enthusiasm for Teilhard de Chardin’s writings, which seek to reconcile Christian faith with scientific evolutionary theory, and his fascination with the figure of Christ himself. By taking a broad and nuanced view of Rubbra’s spirituality, and by subjecting the music itself to close analytical scrutiny, the thesis presents a more multi-faceted view of Rubbra’s life and music than is available in the existing literature and contributes towards a scholarly re-evaluation of Rubbra’s place within twentieth-century British music.
Patterns of Late Glacial vegetation in The Netherlands

description: Das Weichsel-Spätglazial (ca. 13-000-10.000 Jahre vor heute) markiert den Übergang vom kalten späten Weichsel-Pleniglazial zum wärmeren Holozän. Während dieser Periode änderten sich Klima, Vegetation und die abiotische Landschaft sehr rasch. Die Vegetationsentwicklung im Weichsel-Spätglazial der Niederlande wird in erster Linie durch langfristige Klimaänderungen und an zweiter Stelle durch Veränderungen der Lithologie, Geomorphologie und Hydrologie gesteuert. Pollendiagramme aus verschiedenen Regionen, die das gleiche stratigraphische Intervall umfassen, zeigen oft deutliche Variationen in der Vegetationsgeschichte, die nicht allein mit klimatischen Veränderungen erklärt werden können. Über 400 Profile, die Teile oder das gesamte Weichsel-Spätglazial umfassen, wurden in den Niederlanden von verschiedenen Instituten untersucht. Zur Kompilation von mehr als 250 Pollendiagrammen wurde die European Pollen Databasestruktur genutzt. Datierte Veränderungen im arborealen Pollenbestand bilden die Grundlage des regionalen Zonierungsschemas. Mit Hilfe dieser Daten wurden Iso-Pollen-Karten der wichtigsten Taxa für verschiedene Zeitfenster des Weichsel-Spätglazials konstruiert. Die hohe Beobachtungsdichte palynologischer Daten in den Niederlanden erlaubte die Konstruktion hoch auflösender Iso-Pollen-Karten für den betrachteten Zeitraum. Es gibt eine klare Beziehung zwischen den beobachteten Iso-Pollen-Mustern und dem Landschaftstyp. Es sollte nun möglich sein, klarer zwischen klimatischen und abiotischen Faktoren zu unterscheiden, die die Vegetationsentwicklung steuern.

description: The handicraft sector is booming in India with a demand for it witnessed in the whole world. However, the artisans who engage in the profession fail to witness proper design education and market orientation that equips them to better respond to the sector. There are initiatives taken by the government and NGOs to uplift the lives of these artisans. The paper attempts to understand the impact of one such initiative taken by Kala Raksha Trust to preserve and promote the traditional arts and crafts of Kutch, Gujarat. Kala Raksha Vidhyalaya is an initiative of Kala Raksha that impart design education to the artisans of Kutch district of Gujarat. So far, 116 graduates have graduated from school and are working in the sector. The paper attempt to understand the impact KRV has created on the life of these artisans who graduated from the school. The paper concludes with a Swastika Model of Rural Design Schooling (SMRDS) which has been designed based on the observations made from KRV’s work in the arts and crafts domain.

description: Die quartäre Sedimentfolge der Kärlicher Tongrube ist ein Schlüsselprofil für das Pleistozän Mitteleuropas: (a) Rhein- und Mosel-Terrassenablagerungen belegen die junge tektonische Hebung des paläozoischen Rheinischen Schildes, (b) Löß- und Paläobodenschichten spiegeln spätquartäre Klimaschwankungen wider, (c) Artefakt-Horizonte dokumentieren eine ausgedehnte frühmenschliche Geschichte des Mittelrheinraums, und (d) zahlreiche eingeschaltete Tephralagen — abgelagert während explosiver Vulkaneruptionen im Osteifel-Vulkanfeld — bilden ideale chronostratigraphische Leithorizonte. Die chemische und mineralogische Zusammensetzung zweier phonolithischer Bims-Fallablagerungen, die bisher als „Wehrer Bimse" bezeichnet wurden, unterscheidet sich drastisch von schlotnahen Tephraablagerungen am Wehr-Vulkan selber. Darüber hinaus zeigen (40)Ar/(39)Ar-Laseranalysen von Feldspat-Kristallen, daß die beiden Tephraablagerungen, mit Eruptionsaltern von 452.000 ± 8.000 Jahren vor Heute (KAE-DT2) und < 618.000 ± 13.000 Jahren v. h. (KAE-DTl), bis zu doppelt so alt sind, wie bislang angenommen. Schlotnahe, strombolianisch-phreatomagmatische, mafische Tephraschichten (KAE-BT4; lokale Bezeichnung: „Brockentuff"), die einem interglazialen Paläobodenhorizont im Hangenden der jüngeren Bimsablagerung eingeschaltet sind (lokale Bezeichnung: „Kärlicher Interglazial"), stammen von einem heute erodierten, kleinen Eruptionszentrum NW der Tongrube. (40)Ar/(39)Ar-Datierungen von Phlogopit-Ein-sprenglingen nach dem Stufenheizungs- und Laserverfahren ergeben für KAE-BT4 ein Eruptionsalter von 396.000 ± 20.000 Jahren v. h. Unsere Untersuchung zeigt, daß das Kärlicher Profil vor allem terrestrische Pleistozänablagerungen enthält, die zur Zeit der marinen Sauerstoffisotopenstadien 11 bis 19 abgelagert wurden. Jüngere Schichten sind nur unvollständig im Hangenden von KAE-BT4 erhalten. Das „Kärlicher Interglazial locus typicus" repräsentiert eine ca. 400.000 Jahre alte interglaziale Klimaphase und wird hier mit dem marinen Sauerstoffisotopenstadium 11 korreliert. Frühmenschliche Artefakte, die in Schichten unmittelbar im Hangenden der Tephra KAE-BT4 auftreten, könnten demnach ebenfalls bis zu ca. 400.000 Jahre alt sein.

description: We extend the Gross-Perry-Yaffe approach of hot flat space instability to Minkowski space. This is done by a saddle point approximation of the partition function in a Schwarzschild wormhole background which is coincident with an eternal black hole. The appearance of an instability in the whole manifold is here interpreted as a black hole pair creation.

Syntax, Parsing and Production of Natural Language in a Framework of Information Compression by Multiple Alignment, Unification and Search

Subjects: subject: Artificial Intelligence (cs.AI)
subject: Computation and Language (cs.CL)

subject: I.2.7

description: This article introduces the idea that "information compression by multiple alignment, unification and search" (ICMAUS) provides a framework within which natural language syntax may be represented in a simple format and the parsing and production of natural language may be performed in a transparent manner. The ICMAUS concepts are embodied in a software model, SP61. The organisation and operation of the model are described and a simple example is presented showing how the model can achieve parsing of natural language. Notwithstanding the apparent paradox of 'decompression by compression', the ICMAUS framework, without any modification, can produce a sentence by decoding a compressed code for the sentence. This is illustrated with output from the SP61 model. The article includes four other examples - one of the parsing of a sentence in French and three from the domain of English auxiliary verbs. These examples show how the ICMAUS framework and the SP61 model can accommodate 'context sensitive' features of syntax in a relatively simple and direct manner.
Some results related to group actions in several complex variables

description: In this talk, we'll present some recent results related to group actions in several complex variables. We'll not aim at giving a complete survey about the topic but giving some our own results and related ones. We'll divide the results into two cases: compact and noncompact transformation groups. We emphasize some essential differences between the two cases. In the compact case, we'll mention some results about schlichtness of envelopes of holomorphy and compactness of automorphism groups of some invariant domains. In the noncompact case, we'll present our solution of the longstanding problem -- the so-called extended future tube conjecture which asserts that the extended future tube is a domain of holomorphy. Invariant version of Cartan's lemma about extension of holomorphic functions from the subvarities in the sense of group actions will be also mentioned.
Past, Present and Future of Muonium

description: Muonium, the atom which consists of a positive muon and an electron, has been discovered by a team led by Vernon W. Hughes in 1960. It is in many respects the most ideal atom available from nature. Due to the close confinement in the bound state muonium can be used as an ideal probe of electro-weak interaction, including particularly Quantum Electrodynamics, and to search for additional yet unknown interactions acting on leptons. Recently completed experiments cover the ground state hyperfine structure, the 1s-2s interval and a search for spontaneous conversion of muonium to antimuonium. The experiments yield precise values for the fine structure constant, the muon mass and its magnetic moment. The results from these precision measurements have provided restrictions for a number of theories beyond the Standard Model of particle physics. Future precision experiments will require new and intense sources of muons.

Supermarket Contracts, Income, and Changing Diets of Farm Households: Panel Data Evidence from Kenya

description: In many developing countries, supermarkets are increasingly replacing traditional markets as preferred points of food purchases in urban areas. This has welfare implications on smallholder farmers that supply supermarkets. While previous studies have analyzed the welfare effects of smallholder participation in supermarket channels, many have focused on economic effects alone. Very little is known about the effects on farm household diets. Besides, most existing studies that have looked at economic effects used cross-sectional data that are limited in controlling for time-invariant differences between supermarket and traditional channel farmers. This study uses panel data from vegetable farmers in Kenya to examine the effects of supermarket contracting on farm household income and diets. Supplying supermarkets has increased household income by 66%, and is associated with 8% higher consumption of calories, as well as better dietary diversity, and higher levels of zinc consumption. Using these results for simple simulations suggests that wider participation of smallholders in supermarket channels could reduce the prevalence of undernourishment by 8% and the prevalence of zinc deficiency by 12%. Hence, enhancing smallholder market access could significantly contribute to reduction of undernourishment and micronutrient malnutrition and increased income of farm households.
