Non-linear models with panel data [PDF]
Working Paper Series, 2002 Panel data play an important role in empirical economics. With panel data one can answer questions about microeconomic dynamic behavior that could not be answered with cross sectional data. Panel data techniques are also useful for analyzing cross sectional data with grouping.

Modelling the effects of air pollution on health using Bayesian dynamic generalised linear models [PDF]
, 2008 The relationship between short-term exposure to air pollution and mortality or morbidity has been the subject of much recent research, in which the standard method of analysis uses Poisson linear or additive models.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A comment about estimable functions in linear models with non estimable constraints
Revista Colombiana de Estadística, 1999 In the Searle's (1987) book, Linear Models for Unbalanced Data, a characterization of the estimable functions in linear models with non estimable constraints is presented.

Falsifying cosmological models based on a non-linear electrodynamics
European Physical Journal C: Particles and Fields, 2018 Recently, the nonlinear electrodynamics (NED) has been gaining attention to generate primordial magnetic fields in the Universe and also to resolve singularity problems. Moreover, recent works have shown the crucial role of the NED on the inflation. This

Non-Linear Models: Applications in Economics [PDF]
SSRN Electronic Journal, 2006 The study concentrated on demonstrating how non-linear modelling can be useful to investigate the behavioural of dynamic economic systems. Using some adequate non-linear models could be a good way to find more refined solutions to actually unsolved problems or ambiguities in economics.

On the predictability of common risk factors in the US and UK interest rate swap markets: Evidence from non-linear and linear models. [PDF]
This paper explores the ability of common risk factors to predict the dynamics of US and UK interest rate swap spreads within a linear and a non-linear framework.
