The Existence of Aggregate Production Functions [PDF]
Econometrica, 1969 This paper discusses recent work on the existence of aggregate production functions in models in which capital goods are specific to firms and cannot be used interchangeably. It is found that this raises problems not only for capital aggregation but also for the existence of labor and output aggregates.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A Generalized Knowledge Production Function [PDF]
This paper presents a generalized production model based on the knowledge production function. The model allows the relationships between corporate competitiveness strategy, innovation, efficiency, productivity growth and outsourcing to be investigated ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

The normalized CES production function: theory and empirics [PDF]
The elasticity of substitution between capital and labor and, in turn, the direction of technical change are critical parameters in many fields of economics.

The Time Augmented Cobb-Douglas Production Function
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019 The main objective of this paper is to propose and verify a time augmentation of the Cobb-Douglas production function parameters which should be able to capture changing conditions over time.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

"A Theory of Production" The Estimation of the Cobb-Douglas Function: A Retrospective View [PDF]
The Cobb-Douglas production function is still today the most ubiquitous form in theoretical and empirical analyses of growth and productivity. The estimation of the parameters of aggregate production functions is central to much of today's work on growth,
