Optimal Policy and Non-Scale Growth with R&D Externalities [PDF]

open access: yes
An established result of the endogenous growth literature is that competitive equilibria in expanding-varieties models are suboptimal due to the rent-effect: monopolistic pricing drives the equilibrium quantity of each intermediate below the efficient ...

A 3-dimensional singular kernel problem in viscoelasticity: an existence result

open access: yes, 2018
Materials with memory, namely those materials whose mechanical and/or thermodynamical behaviour depends on time not only via the present time, but also through its past history, are considered.

A dynamic multi‐scale occupancy model to estimate trends in habitat use in spatially and temporally complex systems

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Species occurrence is often influenced by changes in environmental conditions at multiple spatial and temporal scales working simultaneously in a hierarchical fashion. While previous dynamic multi‐scale occupancy modelling frameworks address dynamics at multiple spatial scales, they assume both large‐scale and small‐scale units are closed ...

Markets fo Heterogeneous Products: a Boundedly Rational Consumer Model [PDF]

open access: yes
The paper is based on the acknowledgement that properties of markets stemming from features of demand are too frequently overlooked in the economic literature, and a re-balancing is necessary to properly account for theoretical and empirical phenomena ...

Inferring state‐dependent diversification rates using approximate Bayesian computation

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract State‐dependent speciation and extinction (SSE) models are a popular framework for quantifying whether species traits have an impact on evolutionary rates and how this shapes the variation in species richness among clades in a phylogeny.

Proteomic and Transcriptomic Signatures of Poor Asthma Symptom Control in the U‐BIOPRED Cohort

open access: yesAllergy, EarlyView.
No stable features were identified as associated with asthma symptom control in transcriptomics or sputum proteomics. Higher TWEAKR/TNFRSF12A and MBL/MBP‐C serum levels increased the odds of uncontrolled symptoms, while higher MK08/MAPK8 and CD5L serum levels decreased the odds, after adjustment for clinical variables.

Polyglycolic Acid Polymer Versus Porcine Small Intestine Submucosa Graft After Plaque Incision in Peyronie's Disease: A Comparative Study

open access: yesAndrology, EarlyView.
ABSTRACT Background Peyronie's disease (PD) with severe penile curvature often requires surgical correction through plaque incision and grafting (PIG). Objectives To compare surgical outcomes between polyglycolic acid polymer grafts and porcine small intestinal submucosa (SIS) grafts in patients undergoing PIG for PD.

Artificial intelligence chatbots mimic human collective behaviour

open access: yesBritish Journal of Psychology, EarlyView.
Abstract Artificial Intelligence (AI) chatbots, such as ChatGPT, have been shown to mimic individual human behaviour in a wide range of psychological and economic tasks. Do groups of AI chatbots also mimic collective behaviour? If so, artificial societies of AI chatbots may aid social scientific research by simulating human collectives.

Pseudo-NK: an Enhanced Model of Complexity [PDF]

open access: yes
This paper is based on the acknowledgment that NK models are an extremely usefu l tool in order to represent and study the complexity stemming from interactions among components of a system.
