Quadratic engel curves and consumer demand [PDF]
, 1997 This paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative ...

Engel conditions and symmetric tensors [PDF]
Linear and Multilinear Algebra, 2011 In a recent study of Engel Lie rings, Serena Cicalo` and Willem de Graaf have given a practical set of conditions for an additively finitely generated Lie ring L to satisfy an Engel condition. We present a simpler and more direct proof of this fact.

Optimization of the Production of Rubber Compounds Using Mathematical Models
Advanced Engineering Materials, EarlyView.Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Analysis of incomplete remission cases in post-surgery patients with focal drug-resistant epilepsy
Эпилепсия и пароксизмальные состоянияBackground. Epilepsy surgery is mainly aimed at removing patient seizures. Despite the high efficiency of surgical treatment, a search for probable predictors of adverse outcomes and the analysis of the quality of life (QoL) in patients attempted to be ...

Integrability of Reeb Distribution Associated to a Generalized Engel Manifold
Journal of MathematicsIn this paper, we define a generalized Reeb distribution of an Engel 4n-manifold and give a necessary and sufficient condition for integrability of this Reeb distribution which gives a generalization of some results of N.

Assessing Strengths and Limitations of Magnetoencephalography Source Imaging With Intracerebral EEG
Advanced Science, EarlyView.Simultaneous MEG and stereotactic EEG (SEEG) recordings provide a direct validation framework for MEG source imaging in focal epilepsy. Virtual SEEG signals derived from MEG reconstructions reveal significant agreement with intracranial measures of spike localization, resting‐state oscillations, and functional connectivity, while also identifying ...

Food Tastes in the United States: Convergence or Divergence?
Agribusiness, EarlyView.ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.
