To achieve and maintain optimal health, it is essential that the vitamins in foods are present in sufficient quantity and are in a form that the body can assimilate. Vitamins in Foods: Analysis, Bioavailability, and Stability presents the latest information about vitamins and their analysis, bioavailability, and stability in foods.
For bidirectional associate memory neural networks with time-varying delays, the problems of determining the exponential stability and estimating the exponential convergence rate are investigated by employing the Lyapunov functional method and linear matrix inequality (LMI) technique. A novel criterion for the stability, which give information on the delay-dependent property, is derived.
We obtain general results on the stability of mixing and rapid mixing (superpolynomial decay of correlations) for hyperbolic ﬂows. Amongst C r Axiom A ﬂows, r ≥ 2, we show that there is a C 2 -open, C r -dense set of ﬂows for which each nontrivial hyperbolic basic set is rapid mixing. This is the ﬁrst general result on the stability of rapid mixing (or even mixing) for Axiom A ﬂows that holds in a C r , as opposed to H¨lder, topology. o
This paper introduces the notion of a stability condition on a triangulated category. The motivation comes from the study of Dirichlet branes in string theory, and especially from M.R. Douglas’s work on Π-stability. From a mathematical point of view, the most interesting feature of the deﬁnition is that the set of stability conditions Stab(D) on a ﬁxed category D has a natural topology, thus deﬁning a new invariant of triangulated categories.
This paper analyzes the stability of linear, lumped, quadratic, and cubic spatial interpolation functions in finite element one‐dimensional kinematic wave schemes for simulation of rainfall‐runoff processes. Galerkin’s residual method transforms the kinematic wave partial
What makes populations stabilize? What makes them fluctuate? Are populations in complex ecosystems more stable than populations in simple ecosystems? In 1973, Robert May addressed these questions in this classic book. May investigated the mathematical roots of population dynamics and argued-counter to most current biological thinking-that complex ecosystems in themselves do not lead to population stability.
Stability is a basic concern in both design and analysis of load-carrying systems and
constitutes a major topic in the field of engineering science and mechanics. Since
structural instability may lead to catastrophic failure of engineering structures,
stability requirements must be satisfied besides requirements related to material
failure. Knowledge on stability is of great importance in the areas of Civil Engineering,
Mechanical Engineering and Aerospace Engineering; and all these disciplines have
their own literature related to the subject....
Purposes of the research Building a new method (method directly applicable limit theorem) evaluate soil stabilization in accordance with the actual working of the soil environment, the study contributes to the development of stable subgrade; applying the above method to build a computer program, set the tables and nomogram helps engineers quickly determine the height and slope of embankment limited.

This publication presents agronomic reasons which have led to the
development of controlled-release and stabilized fertilizers. The
characteristics, the advantages and the possible disadvantages of
controlled-release and nitrification/urease inhibitors are discussed.
Particular attention is given to problems of legislation, registration,
methodology and standardization.
Leading manufacturers and their product ranges are listed.
This paper considers the exponential stability and stability radius of time-invarying dynamic equations with respect to linear dynamic perturbations on time scales. A formula for the stability radius is given.
Keywords and phrases: time scales, exponential function, linear dynamic equation, exponentially stable, stability radius
This paper deals with a formula of stability radii for an linear difference equation (LDEs for short) with the coefficients varying in time under structured parameter perturbations. It is shown that the lp− real and complex stability radii of these systems coincide and they are given by a formula of input-output operator. The result is considered as an discrete version of a previous result for time-varying ordinary differential equations . Keywords: Robust stability, Linear difference equation, Input-output operator, Stability radius
his monograph presents the results of a project entitled Improving Army Doctrine and Planning for Stability Operations. A great deal of activity has been aimed at revising the approach to the planning and implementation of Stabilization, Security, Transition, and Reconstruction (SSTR) operations. The primary emphasis of the
The United States participated in several interventions and state-building efforts during the 1990s, and the rationale for U.S. engagement in such efforts received a new urgency after the 9/11 attacks. However, recent U.S. experiences in Afghanistan and in Iraq, especially, have shown that engaging in stability and reconstruction

This paper examines how corporate financial structure shapes the impact of a financial crisis on the real sector by way of its effects on flows of funds and on corporate real expenditures.
It is one of the first papers to utilize extensive cross-country flow and balance sheet data and also to examine
subcomponents of GDP in the wake of banking and currency crises rather than focusing exclusively on aggregate GDP.
