Mathematical biology and the existence of biological laws
Laws Mathematical biology Contingency Dynamical systems Reducibility
2016/5/30
An influential position in the philosophy of biology claims that there are no biological laws, since any apparently biological generalization is either too accidental, fact-like or contingent to be na...
Variables, Generality and Existence: considerations on the notion of a concept-script
Stuff Things Matter Objects Non-singular quantification Non-singular reference Count Nouns Mass Nouns and Non-count Nouns
2015/8/5
A defense of the Frege / Russell idea of logic as a 'concept=script' or 'ideal language', and a discussion of the relationship of this project to the formalisation of mass nouns or non-count nouns

Existence and Uniqueness of Optimal Matrix Scalings
diagonal similarity scalings scaled singular value minimization irreducible matrices
2015/7/13
We show that the set of diagonal similarity scalings that minimize the scaled singular value of a matrix is nonempty and bounded if and only if the matrix that is being scaled is irreducible. For an i...

Using Motion-Planning to Determine the Existence of an Accessible Route in a CAD Environment
Accessibility wheeled mobility device motion planning simulation performance-based methods computer-aided design and drafting
2015/6/30
We describe an algorithm based on motion-planning techniques to determine the existence of an accessible route through a facility for a wheeled mobility device. The algorithm is based on LaValle’s wor...
Discrete solitons and vortices in hexagonal and honeycomb lattices: Existence, stability, and dynamics
Dynamic lattice model lattice geometries nonlinear schrodinger equation
2014/12/25
We consider a prototypical dynamical lattice model, namely, the discrete nonlinear Schrödinger equation on nonsquare lattice geometries. We present a systematic classification of the solutions th...
Existence, Stability, and Dynamics of Bright Vortices in the Cubic-Quintic Nonlinear Schr¨odinger Equation
Eddy current stable coupling two-dimensional whirlpool coupling whirlpool
2014/12/24
We study the existence and azimuthal modulational stability of vortices in the two-dimensional (2D) cubic-quintic nonlinear Schr¨odinger (CQNLS) equation. We use a variational approximation (VA) based...
Existence and stability of multisite breathers in honeycomb and hexagonal lattices
Discrete respirator non-square klein Gordon coupling two vortex breath whirlpool hexagonal lattice
2014/12/24
We study the existence and stability of multisite discrete breathers in two prototypical non-square Klein–Gordon lattices, namely a honeycomb and a hexagonal one. In the honeycomb case we consider six...
An organizational economics approach to the existence of sharecropping
share contract fixed rent contract bargaining power
2014/2/24
The paper provides a new explanation for the existence of sharecropping in agriculture from the perspective of organizational economics. Similar to a multinational enterprise’s decision of whether to ...
Second Order BSDEs with Jumps, Part II: Existence and Applications
Second order backward stochastic differential equation backward stochas-tic differential equation with jumps
2012/9/14
In this paper, we follow the study of second order BSDEs with jumps started in our accompanying paper [17]. We prove existence of these equations bya direct method,thus providing complete wellposednes...
Existence of Financial Equilibria in Continuous Time with Potentially Complete Markets
Potentially complete market Continuous-time financial market Radner equilibrium It坥 diffusion
2012/9/14
We prove that in smooth Markovian continuous杢ime economies with potentially complete asset markets, Radner equilibria with endoge-nously complete markets exist.
Theoretical Interpretation of the Existence at 40℃ of an Absolute Maximum of the Hydration Rate of Calcium Sulphate Hemi Hydrate under Microwave Irradiation
Microwave Isothermal Calorimetry Calcium Sulphate Hemi Hydrate Kinetics
2013/1/31
The temperature influence factor on the kinetics of hydration of hemi hydrated calcium sulphate β has been studied in this work under microwave irradiation between 10℃ and 50℃ by isothermal calorimetr...
On the Existence of Bertrand-Nash Equilibrium Prices Under Logit Demand
Bertrand-Nash Equilibrium Prices Logit Demand
2011/1/4
This article presents a proof of the existence of Bertrand-Nash equilibrium prices with multi-product firms and under the Logit model of demand that does not rely on restrictive assumptions on product...
On the Existence of the MLE for a Directed Random Graph Network Model with Reciprocation
Algebraic statistics Dyadic independence Exponential random graph model
2010/10/14
Holland and Leinhardt (1981) proposed a directed random graph model, the p1 model, to describe dyadic interactions in a social network. In previous work (Petrovic et al., 2010), we studied the algebra...
