Exploitation of Rabbits at the Dawn of the Holocene: Evidence From the Font Voltada Site (Northeastern Iberia) Using Comparative Neotaphonomic Models

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT During the transition from the Pleistocene to the Holocene, hunter‐gatherer societies in the northeastern Iberian Peninsula increased the number of settlements and broadened their subsistence strategies. This period is marked by the appearance of terrestrial snail accumulations attributable to human harvesting, the expansion of specialized ...

Expansion of the Brazilian Sugarcane Bioenergy System Promotes Greenhouse Emission Reductions and Sustainable Development Without Compromising Food Security

open access: yesSustainable Development, EarlyView.
ABSTRACT The growing global demand for biofuels has raised concern about compromising food security. This study uses two independent economy‐wide models to evaluate the impact of expanding the Brazilian sugarcane bioenergy system on economic growth, social outcomes and food security.

Clinical Features of Cellular Senescence Pathways in Severe Asthma

open access: yesAllergy, EarlyView.
In bronchial biopsies, SASP and p53 pathway enrichment scores are elevated in severe asthma versus non‐severe asthma and healthy controls. SASP enrichment is validated in the independent NOVA cohort. SASP enrichment is also elevated in nasal brushings of participants with nasal polyps, independently of asthma status.

Examıning impacts of natural sciences education in comparison with health and socıal sciences for pro-environmental behaviours in Turkey

open access: yes, 2015
Analysis of academic programmes has become very important for pro-environmental behaviours; however, impacts of natural, social and health sciences education for environmental knowledge and behaviours have not been investigated yet. Therefore, the aim of

Longer Asthma Duration Is Associated With Elevated Non‐T2 Sputum Biomarkers and Reduced T2 Inflammation in Severe Asthma

open access: yesAllergy, EarlyView.
Longer asthma duration is associated with increased airway non‐T2 inflammation and reduced airway and systemic T2 inflammation. Sputum CXCL9 is independently associated with duration and may predict a reduced poor response to anti‐IL‐4Rα therapy. Airway sampling and combined T2 and non‐T2 targeted strategies may be needed in long‐standing asthma. CXCL9,

Exploring Toothbrushing Duration Among Adults: A Systematic Review

open access: yesInternational Journal of Dental Hygiene, EarlyView.
ABSTRACT Aim There is a need for greater understanding of the average brushing time among individuals. Since the average brushing time remains unclear, this study involves a systematic review to assess this aspect of oral hygiene practices and how it has evolved over the years. Material and Methods The PubMed‐MEDLINE and Cochrane‐CENTRAL databases were

Functional Vašiček Model

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We propose a new formulation of the Vašičekmodel within the framework of functional data analysis. We treat observations (continuous‐time rates) within a suitably defined trading day as a single statistical object. We then consider a sequence of such objects, indexed by day.

Reinforcement Learning for Jump‐Diffusions, With Financial Applications

open access: yesMathematical Finance, EarlyView.
ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

open access: yesMathematical Finance, EarlyView.
ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.
