Anomalous climatic outcomes such as higher temperatures, intense rainfall and flood, frequent and severe droughts are now at the new level. Without appropriate adaptation measures, climate change is bound to exacerbate vulnerability of society, place food security and human health at risk, threaten the lives of growing urban population and impede the goal of attaining sustainable development. The human and social dimensions of climate change, including climate policy, are essential parts of our response to the many challenges emanating from climate change....

The statistical analysis of multivariate data requires a variety of techniques that are entirely different from the analysis of onedimensional data. The study of the joint distribution of many variables in high dimensions involves matrix techniques that are not part of standard curricula. The same is true for transformations and computerintensive techniques, such as projection pursuit.

We identify the symmetry algebra of the Laplacian on Euclidean space as an explicit quotient of the universal enveloping algebra of the Lie algebra of conformal motions. We construct analogues of these symmetries on a general conformal manifold. 1. Introduction The space of smooth ﬁrst order linear diﬀerential operators on Rn that preserve harmonic functions is closed under Lie bracket. For n ≥ 3, it is ﬁnitedimensional (of dimension (n2 + 3n + 4)/2). Its commutator subalgebra is isomorphic to so(n + 1, 1), the Lie algebra of conformal motions of Rn .

An important problem in conformal geometry is the construction of conformal metrics for which a certain curvature quantity equals a prescribed function, e.g. a constant. In two dimensions, the uniformization theorem assures the existence of a conformal metric with constant Gauss curvature. Moreover, J. Moser [20] proved that for every positive function f on S 2 satisfying f (x) = f (−x) for all x ∈ S 2 there exists a conformal metric on S 2 whose Gauss curvature is equal to f . A natural conformal invariant in dimension four is 1 Q = − (∆R −...

Let G be a connected reductive group. The late Ramanathan gave a notion of (semi)stable principal Gbundle on a Riemann surface and constructed a projective moduli space of such objects. We generalize Ramanathan’s notion and construction to higher dimension, allowing also objects which we call semistable principal Gsheaves, in order to obtain a projective moduli space: a principal Gsheaf on a projective variety X is a triple (P, E, ψ), where E is a torsion free sheaf on X, P is a principal Gbundle on the open set U where E is locally free and ψ is an isomorphism...

We show that the Dirichlet to Neumann map for the equation ∇·σ∇u = 0 in a twodimensional domain uniquely determines the bounded measurable conductivity σ. This gives a positive answer to a question of A. P. Calder´n o from 1980. Earlier the result has been shown only for conductivities that are suﬃciently smooth. In higher dimensions the problem remains open. Contents Introduction and outline of the method

Two elements instil a degree of moderate optimism going forward. First, major policy decisions have significantly reduced tail risks and relieved market stress. The June European Council decisions were swiftly followed up with concrete progress towards establishing a Banking Union. The European Council of 1819 October agreed on a timetable for the establishment of a Single Supervisory Mechanism and advanced further on the deepening of EMU, encompassing the financial, budgetary, economic, and political dimensions.

Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the selectivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying.

Semisuspension technology for preparation of tetrabasic lead sulfate pastes for leadacid batteries
A new technology for production of 4BS pastes for the positive (lead dioxide) plates of leadacid batteries has been developed based on an Eirich Evactherm1 mixer. The basic principle of this new technology is that 4BS crystals with dimensions between 20 and 25 mm are formed ®rst from a semisuspension at a temperature higher than 908C and then the excess water is removed from the semisuspension under vacuum until the desired paste density is obtained. During the vacuum treatment the temperature of the paste decreases and small 4BS and PbO crystals are formed. ...

This is the second book of examples from the Theory of Probability. This topic is not my favourite, however, thanks to my former colleague, Ole Jørsboe, I somehow managed to get an idea of what it is all about. The way I have treated the topic will often diverge from the more professional treatment. On the other hand, it will probably also be closer to the way of thinking which is more common among many readers, because I also had to start from scratch.

While disentangling the returns to schooling from the returns to unobserved ability is diﬃcult, estimating the returns to college quality is harder still. No good instruments have been found for college quality, and the sample sizes of twins are often too small to obtain accurate estimates of the returns to college quality. 6 A notable exception is Berhman et al. (1996), who ﬁnd that, after controlling for family background characteristics using twins, there are signiﬁcant returns to attending colleges of higher “quality” in several observable dimensions.

Our study investigates how ultimate ownership structure and the corporate tax rate affect the equilibrium tradeoff relation between manager ownership and debt in reducing agency costs. Considering the presence of the controlling shareholder, we find that higher corporate tax rates strengthen the tradeoff relation between manager ownership and debt while higher control rights held by the controlling shareholder weaken it as well as the strengthening effect of corporate tax rate.

lasso estimates can be obtained at the same computational cost as that of an ordinary least squares estimation Hastie et al. (òýýÀ). Further, the lasso estimator remains numerically feasible for dimensions m that are much higher than the sample size n. Zou and Hastie (òýý ) introduced a hybrid PLS regression with the so called elastic net penalty dened as "Ppj =Ô(ò ( j + Ô −)SjS). Here the penalty function is a linear combination of the ridge regression penalty function and lasso penalty function. A dierent type of PLS, called garotte is due to Breiman (ÔÀÀç).
