description: We have studied the effects of chirped femtosecond laser pulses on the formation of ultracold molecules in a Rb magneto-optical trap. We have found that application of chirped femtosecond pulses suppressed the formation of 85Rb-2 and 87Rb-2 lowest triplet state molecules in contrast to comparable non-chirped pulses, cw illumination, and background formation rates. Variation of the amount of chirp indicated that this suppression is coherent in nature, suggesting that coherent control is likely to be useful for manipulating the dynamics of ultracold quantum molecular gases.

Paläoklimatologische Eindrücke aus Neuseeland

Publisher: name: Geozon Science Media

description: Einige Beobachtungen und Bemerkungen zum Klima und Paläoklima von Neuseeland aufgrund von Reisen und der Arbeiten von neuseeländischen Geologen werden mitgeteilt. Einige Eigenheiten des Klimas. Wie Tasmanien hat Neuseeland relativ kühles und feuchtes Klima. Die Regenschattenwirkung der Gebirge ist besonders deutlich und damit im Zusammenhang der Wechsel der Vegetation. Im Vulkangebiet der Nordinsel gibt es Anfänge „edaphisch bedingter Wüsten". Die Gletscher an der Westküste, besonders der Franz-Josef- und der Fox-Gletscher, sind eindrucksvolle Beispiele für das Nebeneinander üppiger, fast subtropischer Regenwälder (mit Baumfarnen) und Gletschereis und daher für den Paläoklimatologen und die Ausdeutung fossiler Gletscherspuren sehr wichtig. Beide Gletscher enden nicht weit vom Meer, fast 2000 m unter der Schneegrenze; sie haben sich in 21 Jahren um 1200 bzw. 1800 m zurückgezogen. Die Ursache für die tiefe Lage der Gletscherzunge liegt im hohen Niederschlag und in der Höhe und Steilheit des Gebirges. Die Klimageschichte Neuseelands. Das Quartär wird nicht näher behandelt, der Einfluß junger tektonischer Bewegungen auf die Terrassen erwähnt. Das Klima des Tertiärs war gemäßigt bis subtropisch und humid. Das Temperatur-Maximum lag nicht, wie in Europa und Nordamerika, im älteren, sondern (wie in Australien) im mittleren Tertiär. Das wird vom Autor zu erklären versucht durch die Kombination zweier Kurven: einmal der drift-bedingten Änderung der lokalen Breitenlage, zum anderen der allgemeinen Tendenz der Temperaturabnahme auf der Erde im Tertiär. Da mindestens Australien im Tertiär offenbar äquatorwärts wanderte, Europa dagegen allenfalls polwärts, verläuft die resultierende Kurve in beiden Gebieten verschieden. — Auch das Mesozoikum ist nicht tropisch und nicht arid. Das Perm ist möglicherweise etwas wärmer als in Australien gewesen. Der Unterschied der Klimaentwicklung zu Australien ist auffällig. Australien wanderte seit dem Karbon-Perm von einer polaren Klimazone bis in die Subtropen und Tropen. Neuseeland dagegen verharrte möglicherweise ± im gleichen Klimagebiet. Es läßt sich noch nicht sagen, ob der Unterschied nur vorgetäuscht ist (durch lückenhafte Überlieferung), oder aber dadurch bedingt wird, daß beide Gebiete unabhängig voneinander nach Norden wanderten (Australien schnell, Neuseeland langsamer).

description: A recent paper by Doole and Marsh (2013), questioned the validity of using the New Zealand Forest and Agriculture Regional Model (NZFARM) for New Zealand agri-environmental policy analysis. We respond to their critique by clearly describing the model structure, explaining the NZFARM parameterisation, calibration, and validation procedure, and presenting estimates from a series of nutrient reduction policy scenarios to highlight the utility of the model. In doing so, we demonstrate that NZFARM generates logical and intuitive results that can be used for robust agri-environmental policy decision-making.

description: The precision measurement of the $β-$spectrum shape for $^{210}$Bi (historically RaE) have been performed with a spectrometer based on semiconductor Si(Li) detector. This first forbidden non-unique transition has the transition form-factor strongly deviated from unity and knowledge of its spectrum would play an important role in low-background physics in presence of $^{210}$Pb background. The measured transition form-factor could be approximated as $S(W) = 1 + (-0.4363 \pm 0.0037) W + (0.0523 \pm 0.0010) W^2$, that is in good agreement with previous studies and has significantly increased parameter precision.

Music and poetry in Mallarmé and Debussy
Creators: name: Wilson, Geoffrey Allan
Publisher: name: University of British Columbia
Year: 2011

description: My dissertation re-evaluates music and poetry in the works of Claude Debussy and Stéphane Mallarmé. Often in such collaborations, critics assume that the music mimics various aspects of the texts it engages. Instead, I argue for a more nuanced paradigm that values both concurrences and antagonisms between the two media, in light of the specific systems of thought characterizing, respectively, the poet and the musician. Chapter One re-evaluates the role of music in Mallarmé's oeuvre. Mallarmé imagined an original language in which individual phonemes created the meaning of words. As languages evolved and multiplied, the sound-sense relationship in words became increasingly arbitrary. Traces of this original language are visible in contemporary idioms when a group of words share both a phonemic and a semantic link. For him, poetry exists to reconstruct sound-sense relationships in modern language. These relationships, and the patterns of thought they enact, are music for Mallarmé, a music which the sound of instruments and singers merely implies. Drawing evidence from Mallarmé's letters and critical writings, I establish the "musical" nature of his language and show its use in analyses of selected poems. In the remaining chapters I examine each of Debussy's compositions that engage a Mallarmé text: the songs Apparition, Soupir, Placet futile, Éventail, and the Prélude à l'après-midi d'un faune. I chronicle Debussy's early exposure to Mallarmé's poetry through Verlaine's essay "Les poètes maudits" and the song Apparition that resulted. Here, Debussy responds to the semantic content of Mallarmé's poem, constructing a musical "apparition" to parallel the poetic one. I offer a new reading of Prélude that relates it to Mallarmé's dramatic theories, and not as a mimetic illustration of the poem's text. I argue that Debussy's later song settings allow Mallarmé's poetic "music" to be perceived alongside his own. In Soupir, this is manifested through a series of mirror images in both music and text. In Placet futile, I show how the music alters the semantic message of the poem. In Éventail, I compare the interaction of wholetone, octatonic and diatonic pitch collections to the interaction between the phonetic and semantic layers of the poem.

description: In order to understand characteristics common to distributions which have both fractal and non-fractal scale regions in a unified framework, we introduce a concept of typical scale. We employ a model of 2d gravity modified by the $R^2$ term as a tool to understand such distributions through the typical scale. This model is obtained by adding an interaction term with a typical scale to a scale invariant system. A distribution derived in the model provides power law one in the large scale region, but Weibull-like one in the small scale region. As examples of distributions which have both fractal and non-fractal regions, we take those of personal income and citation number of scientific papers. We show that these distributions are fitted fairly well by the distribution curves derived analytically in the $R^2$ 2d gravity model. As a result, we consider that the typical scale is a useful concept to understand various distributions observed in the real world in a unified way. We also point out that the $R^2$ 2d gravity model provides us with an effective tool to read the typical scales of various distributions in a systematic way.

description: We apply the Gamow shell model to study $^{25-31}$F isotopes. As both inter-nucleon correlations and continuum coupling are properly treated therein, the structure shape of $^{31}$F at large distance can be analyzed precisely. For this, one-nucleon densities, root-mean square radii and correlation densities are calculated in neutron-rich fluorine isotopes. It is then suggested that $^{31}$F exhibits a two-neutron halo structure, built from both continuum coupling and nucleon-nucleon correlations.

title: Middle schools: a sociological interpretation of their development and practice
Creators: name: Bryan, Kenneth A.
Publisher: name: The Open University
Year: 1980

description: Middle schools as separate and distinct institutions are still a relatively recent feature in the maintained school system in England. This new category of schools is not a homogeneous one. The two main types of middle school tater for pupils aged either 8 - 12 or 9 - 13 years, but there are other variants whose pupils are in the age range 9 - 12, 10 - 13 and 10 - 14 years. Administratively middle schools are 'deemed' either primary or secondary. First, this study sets out to analyse the development of middle schools in England within the context of comprehensive secondary school re-organisation. Then the decision to adopt middle schools of different types in two L.E.A.'s is examined in some detail. The intention is to explore how far decision making at the L.E.A. level about the form of school systems illustrates the considerations which appear to operate at the level of central government. In the second part, aspects of life in two specific middle schools are explored from the points of view of teachers and pupils. Again the intention is to explore how far and in what ways issues relating to middle school planning at the central and local government level make their impact in particular schools. The central theme throughout this study is the degree of congruence between the rhetoric used to legitimate middle schools and the reality experienced within them. The problem of linking 'macro' and 'micro' levels of analysis is a familiar and persistent one in the sociology of education. In this study a theoretical synthesis to link decisions made about middle schools at central, government, local education authority and school ,level is made by way of an adaptation of exchange theory. It is suggested that this theoretical stance both clarifies and illuminates the data presented in the thesis and provides a framework in which future middle school developments can be located and interpreted.

DESCRIPTION
The test is slightly elongated oval with an axial diameter of 1.01- 1.41 mm and equatorial diameter of 0.45-0.78 mm. Index of elongation is between 1.79-2.71. The first 4-5 whorls which follow the proloculus are devoid of an axial thickening, so that the shape of the test seems spheric in this stage. Axial thickening increases at the last 4 whorls, therefore the shape of the test becomes elongated oval in the adult stage.Dimorphism is faint.

title: The Froebel movement and state schooling 1880-1914 : A study in educational ideology
Creators: name: Brehony, Kevin Joseph
Publisher: name: The Open University
Year: 1988

description: This thesis examines the relation between the Froebel movement and state schooling in England between 1880 and 1914. It is argued that the Froebelian pedagogy functioned as an ideology which expressed the interests of middle class women in the sphere of schooling and in particular, the interests of such women who were for political or religious reasons excluded from the dominant culture of the hegemonic fraction of the power bloc. It is further argued that the relation between the Froebel movement and state schooling during the period may best be approached through a consideration of the articulation of Froebelian ideology with ideologies of industrial modernization and national efficiency which were advanced by groups who aimed to modernize the schooling of young children who attended state schools. The failure of the Froebelians to transform state schooling in the way that they desired is shown to be not only an effect of their own lack of power and the inappropriateness of their strategies but also an effect of the relative failure of broader attempts to modernize state schooling. The internal transformation of the Froebelian pedagogy is charted and it Is related to external critiques, the main condition of existence of which was a search for a science of education which was linked to the perceived need for a new type of teacher. This transformation is also shown to have been determined by the requirements of the state system of schooling which broadly understood included not only schools but training colleges and state policies as well.

description: Plahte identities are monodromy relations between open string scattering amplitudes at tree level derived from the Koba-Nielsen formula. We represent these identities by polygons in the complex plane. These diagrams make manifest the appearance of sign changes and singularities in the analytic continuation of amplitudes. They provide a geometric expression of the KLT relations between closed and open string amplitudes. We also connect the diagrams to the BCFW on-shell recursion relations and generalise them to complex momenta resulting in a relation between the complex phases of partial amplitudes.

description: As a clinical investigator with the U.S. Public Health Service during the 1930s, Clifton Himmelsbach, M.D., directed the laboratory at the Fort Leavenworth Penitentiary Annex in 1933-34 before establishing the laboratory at the Lexington Narcotics Hospital in 1935. In his early work, Himmelsbach systematically observed and charted withdrawal and abstinence symptoms, thereby laying the foundation for assessing the addictive potential of drugs. An advocate of a multi-disciplinary approach to the problem of addiction, Himmelsbach fostered a unique experimental climate at Lexington, encouraging collaboration and synergistic thinking among the scientists. Dr. Himmelsbach also pioneered the concept of informed consent; he argued that the addicts who served as human subjects in the research at Lexington had much to contribute to the research, often teaching the scientists about drug-taking practices, and that human subjects could gain satisfaction from participating in clinical research. Dr. Himmelsbach died in 1995. Sources: Transcript. “Clifton Keck Himmelsbach” FindAGrave.com. https://www.findagrave.com/memorial/53659947/clifton-keck-himmelsbach Accessed 18 Oct 2021.

description: During the last decades, the study of cities has been transformed by new approaches combining engineering and complexity sciences. Network theory is playing a central role, facilitating the quantitative analysis of crucial urban dynamics, such as mobility, city growth or urban planning. In this work, we focus on the spatial aspects of congestion. Analyzing a large amount of real city networks, we show that the location of the onset of congestion changes according to the considered urban area, defining, in turn, a set of congestion regimes separated by abrupt transitions. To help unveiling these spatial dependencies of congestion (in terms of network betweenness analysis), we introduce a family of planar road network models composed of a dense urban center connected to an arboreal periphery. These models, coined as GT and DT-MST models, allow us to analytically, numerically and experimentally describe how and why congestion emerges in particular geographical areas of monocentric cities and, subsequently, to describe the congestion regimes and the factors that promote the appearance of their abrupt transitions. We show that the fundamental ingredient behind the observed abrupt transitions is the spatial separation between the urban center and the periphery, and the number of separate areas that form the periphery. Elaborating on the implications of our results, we show that they may have an influence on the design and optimization of road networks regarding urban growth and the management of daily traffic dynamics.

description: We investigate the effect of electronic correlations on the coupling of electrons to Holstein phonons in the one-band Hubbard model. We calculate the static electron-phonon vertex within linear response of Kotliar-Ruckenstein slave-bosons in the paramagnetic saddle-point approximation. Within this approach the on-site Coulomb interaction U strongly suppresses the coupling to Holstein phonons at low temperatures. Moreover the vertex function does not show particularly strong forward scattering. Going to larger temperatures kT\sim t we find that after an initial decrease with U, the electron-phonon coupling starts to increase with U, confirming a recent result of Cerruti, Cappelluti, and Pietronero. We show that this behavior is related to an unusual reentrant behavior from a phase separated to a paramagnetic state upon decreasing the temperature.

Cumulative deviation of a subpopulation from the full population

Publisher: name: arXiv
Year: 2020
Subjects: subject: Methodology (stat.ME)

description: Assessing equity in treatment of a subpopulation often involves assigning numerical "scores" to all individuals in the full population such that similar individuals get similar scores; matching via propensity scores or appropriate covariates is common, for example. Given such scores, individuals with similar scores may or may not attain similar outcomes independent of the individuals' memberships in the subpopulation. The traditional graphical methods for visualizing inequities are known as "reliability diagrams" or "calibrations plots," which bin the scores into a partition of all possible values, and for each bin plot both the average outcomes for only individuals in the subpopulation as well as the average outcomes for all individuals; comparing the graph for the subpopulation with that for the full population gives some sense of how the averages for the subpopulation deviate from the averages for the full population. Unfortunately, real data sets contain only finitely many observations, limiting the usable resolution of the bins, and so the conventional methods can obscure important variations due to the binning. Fortunately, plotting cumulative deviation of the subpopulation from the full population as proposed in this paper sidesteps the problematic coarse binning. The cumulative plots encode subpopulation deviation directly as the slopes of secant lines for the graphs. Slope is easy to perceive even when the constant offsets of the secant lines are irrelevant. The cumulative approach avoids binning that smooths over deviations of the subpopulation from the full population. Such cumulative aggregation furnishes both high-resolution graphical methods and simple scalar summary statistics (analogous to those of Kuiper and of Kolmogorov and Smirnov used in statistical significance testing for comparing probability distributions).

title: Representation of Knowledge for Chess Endgames Towards a Self-Improving System
Creators: name: Bramer, Max Arthur
Publisher: name: The Open University
Year: 1977

description: This thesis describes an investigation of the problems involved in representing knowledge within the task area of elementary Chess endgames. Two major criteria are taken for the choice of a model of & the chessplayer's knowledge : firstly, that algorithms constructed using the model should be natural from the viewpoint of a chessplayer and commensurate with his, view of the complexity of the task, and secondly that the algorithms should be capable of refinement in the light of experience in a manner which preserves the previous property. Elementary chess endgames are studied as a field in which programs based on tree-searching and traditional evaluation functions have achieved poor results and where tree-searching seems to play little or no part for people. It is therefore possible to examine problems of knowledge representation and program refinement largely independently of the tree-searching paradigm. A long term aim of the research is to develop a representation suitable as the basis for a fully automatic system of algorithm refinement, whilst maintaining the criteria given above. A model is proposed and algorithms are given for two endgames, King and Rook against King (KRK) and King and Pawn against King (KPK) using this model. It is argued that both algorithms are reasonably natural and compact representations and experiments in refining these algorithms are described in detail. In both cases, the process of refinement is shown to be a reasonably straightforward one (for people) and one which maintains the properties of naturalness and compactness. The possibility of automating this process is considered.

We show that this mechanism produces scale-free networks with degree exponent gamma=3 and clustering coefficients depending on random walk length. The mechanism can be interpreted in terms of preferential attachment without explicit knowledge of node degrees.

Creators: name: Boyd-Barrett, Joseph Oliver
Publisher: name: The Open University

description: The thesis argues that in their development, organization and news services, the major western-based global news agencies have responded and continue to respond primarily to the requirements of western markets. In particular, their domestic markets are shown to be especially important to them, and much of their early development is explained by their struggle to secure monopolistic or oligopolistic control of these markets. The struggle to, achieve security in the domestic markets greatly tempered early international competition between the agencies in a way that still has consequences for their relative market positions in certain world regions, and which has hindered their penetration of one another's domestic markets. Nevertheless, growing international competition, general difficulties in traditional domestic newspaper markets and the evolution of new client requirements have combined to stimulate considerable market diversification in recent decades, both inside and outside media client groups. Within their traditional overseas markets, the global agencies, in their organization of news-gathering and news-distribution, have made considerable use of the national news agencies. The global agencies have stimulated the development of many such agencies, entering into relationships of unequal exchange with them, while only marginally threatened by the attempts of some national agencies to upset the dominant market position of their global partners. The thesis provides evidence of contemporary agency organization, news-gathering practices and news-service content in order to support the argument that there continues to exist a structural imbalance in agency operations which favours western market interests, and to further explore the underlying significance of their organizational priorities.

description: Horizons responsible for the reflection of seismic waves within deep-sea sediments are shown to be less reliable for the purposes of correlation than their counter-parts in shallow margin sequences. Similar surfaces, such as abrupt lithological changes and unconformities, in the two different realms are not neccessarily produced by the same processes. It is the nature of these processes which control the chronostratigraphic significance of a reflector. Thus reflectors may be correlated with reference to their genetic process. Horizons caused by time-restricted physical processes have enhanced chronostratigraphic significance. In the deep-sea, layers in which the physical properties change slowly with depth (transition layers) are also important for reflector formation. In as much as these transitions can be affected by temperature, pressure and sediment geochemistry, as well as time, the equation of an horizon at two different localities does not neccessarily imply correlation in time (i.e. the horizon is not neccessarily a chronostratigraphic time line). The two most important factors affecting impedance are the primary sedimentary geochemical composition and the nature of the grain to grain contacts within the sediment. Impedance increases with increasing grain density and increased rigidity of the sedimentary frame. The inter-dependance of all sediment physical properties greatly complicates the study of the relationships between them. Modelling can be used to demonstrate the affects of variation of individual properties. Synthetic seismograms can be generated using either physical properties data measured from discrete samples or from wire-line data. While quality is a limiting factor to the performance of .-. physical properties modelling, the latter is of value in that it enables modelling at many more localities than is possible with wire-line techniques alone. Abrupt impedance contrasts that produce reflectors important in deep-sea seismic stratigraphy may be grouped into a) Compaction horizons produced by gradual increase in over-burden pressure, b) Cementation horizons produced by variation in diagenesis with depth c) Calcite compensation depth (CCD) controlled horizons characterised by marked variation in primary sedimentary content and d) Unconformities produced by bottom current action.

description: In a disordered system, a quantity is self-averaging when the ratio between its variance for disorder realizations and the square of its mean decreases as the system size increases. Here, we consider a chaotic disordered many-body quantum system and search for a relationship between self-averaging behavior and the properties of the distributions over disorder realizations of various quantities and at different timescales. An exponential distribution, as found for the survival probability at long times, explains its lack of self-averaging, since the mean and the dispersion are equal. Gaussian distributions, however, are obtained for both self-averaging and non-self-averaging quantities. Our studies show also that one can make conclusions about the self-averaging behavior of one quantity based on the distribution of another related quantity. This strategy allows for semianalytical results, and thus circumvents the limitations of numerical scaling analysis, which are restricted to few system sizes.

title: A design and performance prediction method for axial piston pumps with integral controls
Creators: name: Beswarick, William J.
Publisher: name: The Open University
Year: 1978

description: The thesis presents the findings of a programme of research into the design and performance of variable displacement axial piston pumps of the swashplate type with integral controls. The work is principally concerned with developing a systematic design and performance prediction method for use at the design stage. The method developed outlines stage by stage the problems which arise and give guidance on the decisions which have to be made during the design process. Existing theory and technological data is integrated in the method and is augmented by the author's own contributions in the area of force analysis and contact stresses in the cylinder bores. Graphical optimisation methods are employed and the effects of manufacturing tolerances and .pump working ranges are investigated. The effectiveness of the method is demonstrated by designing a pump to the same specification as that of an existing industrial pump and by making a critical comparison of the two designs. Various regions of power loss are identified and equations derived for estimating these losses. The equations are developed and integrated into a performance prediction method which is novel in that unlike any known method, pump performance can be predicted without the need to test a similar pump. Using data readily available at the design stage the method is used to compare the performance of the existing pump with predicted values. Close agreement is claimed as an indication of the reliability of the method. The thesis gives an account of the historical development of the axial piston pump, a survey of published work on design and performance and a description of axial piston pumps and hydrostatic transmissions. Also included is an analytical treatment for the frequency response of servo controlled pumps by manual and electrohydraulic control.

description: Recent wide-field photometric surveys which target a specific field for long durations are ideal for studying both long and short period stellar variability. Here we report on 75 variable stars detected during observations of a field in Pegasus using the WASP0 instrument, 73 of which are new discoveries. The variables detected include 16 delta Scuti stars, 34 eclipsing binaries, 3 BY Draconis stars, and 4 RR Lyraes. We estimate that the fraction of stars in the field brighter than V ~ 13.5 exhibiting variable behaviour with an amplitude greater than 0.6% rms is ~ 0.4%. These results are compared with other wide-field stellar variability surveys and implications for detecting transits due to extra-solar planets are discussed.

title: School phobia: In search of a syndrome
Creators: name: Conn, William John Thomas
Publisher: name: The Open University
Year: 1988

description: This study is concerned with children's anxiety regarding school attendance of which school phobia is the most extreme form. A literature cull identified features believed to typify the school phobics pattern of anxiety and these were included in a battery of instruments administered to a random sample of 225 boys and 261 girls between the ages of 11 and 16 years. This battery was also administered to a sample of 30 clinically defined school phobic boys and 19 school phobic girls. Four groups, validated by a series of Discriminant Function Analyses, emerged in this study. These groups are taken to represent a continuum of anxiety relating to school attendance from severe to anxiety free. Evidence is adduced for the need to evaluate boys and girls data separately. The groups were found to differ for both boys and girls in terms of age and ability but not social class or the number of other fears experienced though slight differences in the nature of fears emerged. Overall the girls groups more commonly reported fears. Difficulties with friendships emerged as highly significant. However there were sex differences in the importance of the age and sex of friends variables and in whether the friends come from the childs own school. Differences also emerged on a specially created Vulnerability in School measure but not on a General Satisfaction with School scale. Sociometric data reliably discriminates among the groups for both boys and girls though generally did not appear to have an impact on favoured spare time activity. The school avoidance strategy of pretending to be sick did not prove to be significant though recourse to truancy did - especially among the boys. Additionally, significantly more sleep and nighttime problems are revealed among the more anxious groups for both boys and girls. The significance of these and associated other findings are analysed and a tentative model of the anxious childs' situation in terms of theories of Stress and Gaping nominated as furnishing a possible synthesis.
Expression of alpha v beta 6 integrin in periodontal disease

description: Integrins are the principal cell surface receptors that mediate cell-to-cell or cell-to-extracellular matrix (ECM) binding, providing adhesion for stationary cells, traction during cell movement and, importantly, translating extracellular matrix cues into intracellular signal transduction pathways. The ανβ6 integrin, an exclusively epithelial integrin, exhibits limited distribution in the body. In adult tissue, ανβ6 integrin is expressed during inflammation, carcinogenesis, and in wound healing. It is not expressed in oral gingival epithelium but it is constitutively expressed in junctional epithelium (JE). Its capability to bind and activate transforming growth factor-β (TGFβ) suggests immune regulation and it could therefore play a protective role against periodontal disease. When comparing hematoxylin and eosin stained paraffin sections of wild-type (FVB) and β6 integrin-knockout mice (β6 -/-) under the light microscope, apical migration of junctional epithelium beyond the cemento-enamel junction (CEJ) resulting in formation of pocket epithelium (PE) was clearly demonstrated only in specimens of β6 integrin-knockout animals. In addition, analysis of defleshed mandibles revealed a significant increase in alveolar bone loss and therefore enhanced exposed root surface area and furcation involvement for knockout mice in comparison to their age matched wild-type animals (FVB). The findings of this study suggest that ανβ6 integrin, exclusively expressed in JE, might play an important role in the pathogenesis of periodontal disease in mice. One possible mechanism could be through its regulatory function in the activation of TGFβ.
