Understanding the Impact of Weights Constraints in Portfolio Theory
In this article, we analyze the impact of weights constraints in portfolio theory using the seminal work of Jagannathan and Ma (2003). They show that solving the global minimum variance portfolio problem with some constraints on weights is equivalent to ...

Financial constraints, capital structure and dividend policy: Evidence from Jordan
, 2013 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The economic reforms in Jordan during the last two decades have highlighted and promoted the role that non-financial firms play within the Jordanian economy.

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Financial Constraints: Routine Versus Cutting Edge R&D Investment [PDF]
We analyze financial constraints for R&D, where we account for heterogeneity among investments which has been neglected in previous literature. According to economic theory, investments should be distinguished by their degree of uncertainty, e.g. routine

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales
Advanced Engineering Materials, EarlyView.Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

The MAMI Theory: Meta–Architecture of Mind and Invisibility [PDF]
The Meta–Architecture of Mind and Invisibility (MAMI Theory) offers a structural account of how invisible cognitive, social, and epistemic events are produced, erased, or retained across education, clinical practice, and AI systems. Rather than treating “

Harmonic Vectors and the Constraints of Tonality
, 2018 International audienceThe theory of harmonic vectors (THV) rests on the hypothesis that tonal functions result from root progressions, not the reverse: it is a transformational theory of the tonal harmonic process.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Probabilistic Constraint Logic Theories. [PDF]
, 2016 Probabilistic logic models are used ever more often to deal with the uncertain relations typical of the real world. However, these models usually require expensive inference procedures. Very recently the problem of identifying tractable languages has come to the fore.

Internal financial constraints, external financial constraints, and investment choice: Evidence from a panel of UK firms [PDF]
This paper uses a panel of 24184 UK firms over the period 1993-2003 to study the extent to which the sensitivity of investment to cash flow differs at firms facing different levels of internal and external financial constraints.
