Extending the hyper‐logistic model to the random setting: New theoretical results with real‐world applications

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.

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.

Trait coevolution and causal inference using generalized dynamic phylogenetic models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Phylogenetic comparative methods are widely used to study trait coevolution across biological and cultural domains. The most common methods are phylogenetic generalized linear (mixed) models, phylogenetic path analysis, Pagel's ‘discrete’ method and Ornstein–Uhlenbeck models. While some frameworks like generalized linear mixed models are quite

TABMON: Design and deployment of a transnational passive acoustic monitoring network for European birds

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Ecological surveys are often fragmented, costly and limited in scale, leading to large and long‐standing knowledge gaps which threaten our ability to properly safeguard biodiversity. Passive acoustic monitoring (PAM) has promised to deliver automated biodiversity monitoring, but networks are rarely deployed on scales that can offer truly novel

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.

Variations in the Risk of New‐Onset Diabetes Following COVID‐19 Infection Across Body Mass Index, Deprivation, Ethnicity and Geographic Regions: Population‐Based Cohort Study in 42 Million People in England

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Evidence suggests that COVID‐19 may be associated with an increased risk of diabetes. We aimed to examine this association by investigating the role of socioeconomic and metabolic factors on the risk of new‐onset type 2 (T2D) and type 1 (T1D) diabetes after COVID‐19 diagnosis. Materials and Methods We conducted a retrospective, population‐

The Effect of Chlorhexidine Mouthwash on Blood Pressure: A Systematic Review and Meta‐Analysis

open access: yesInternational Journal of Dental Hygiene, EarlyView.
ABSTRACT Aim This study evaluated the effect of rinsing with a chlorhexidine containing mouthwash (CHX‐MW) on blood pressure (BP), as compared to rinsing with a control MW or no MW, based on (randomised) controlled trials and observational studies in humans. PROSPERO CRD42020222495.

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.
