Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

open access: yesIntegrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Reduced complexity on-line estimation of hidden Markov model parameters [PDF]

open access: yes, 1998
In this paper we propose and study low complexity algorithms for on-line estimation of hidden Markov model (HMM) parameters. The estimates approach the true model parameters as the measurement noise approaches zero, but otherwise give improved estimates,

The Virtual Pivot: Adaptive Investor Relations in the Face of Disruption Le virage virtuel : le caractère adaptatif des relations avec les investisseurs face aux perturbations

open access: yesContemporary Accounting Research, EarlyView.
ABSTRACT The capacity of firms to communicate effectively with investors during periods of disruption is a critical but understudied dimension of corporate adaptability. The COVID‐19 pandemic offers a rare empirical setting to observe such adaptability: It eliminated in‐person investor events almost overnight, forcing firms to either withdraw from ...

A method to estimate actual infrastructure‐induced mortality by integrating hierarchical sources of imperfect detection

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Human infrastructures are among the most impactful wildlife threats. Although estimates of animal mortality by these structures exist over a given period, they typically do not account for several levels of imperfect detection (i.e. difference between recorded and true mortality).

Flexible unimodal density estimation in hidden Markov models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Hidden Markov models (HMMs) are powerful tools for modelling time‐series data with underlying state structure. However, selecting appropriate parametric forms for the state‐dependent distributions is often challenging and can lead to model misspecification.

The natural history of periodontal disease—Part 2: In populations with access to dental care: The Studies of Health in Pomerania (SHIP)

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract In this descriptive analysis of the 21‐year follow‐up data from the SHIP‐START cohort and the 7‐year follow‐up data from the SHIP‐TREND cohort, we report the progression of clinical attachment levels (CAL), age effects on CAL change, and a detailed description of CAL progression and remission. At baseline, 4307 and 4420 persons participated in

ITSxRust: ITS Region extraction with partial‐chain recovery and structured diagnostics for long‐read amplicon sequencing

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Long‐read amplicon sequencing is now routine for fungal metabarcoding, and locating the internal transcribed spacer (ITS) subregions within reads has become a throughput bottleneck. Existing extractors were designed for shorter reads and for datasets in which near‐identical sequences are common, and neither assumption holds for Oxford Nanopore

Weekend Overload: Day‐to‐Day Fluctuations of Outdoor Recreation Affect Wild Mammals' Space‐Use in a Popular Forest Reserve Near Florence, Italy

open access: yesAnimal Conservation, EarlyView.
In an urban‐adjacent forested area, we investigated the spatial and temporal distribution of the wild mammal community in relation to day‐to‐day fluctuations of human presence occurring between working days and weekends. We deployed 52 camera‐traps systematically within an EU Natura 2000 area located within the metropolitan area of Florence, central ...

Empirical Evidence of Firm States of Corporate Social Responsibility and Irresponsibility: Transition Frequencies and State Drivers

open access: yesBusiness Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT A common assumption is that firms become more socially responsible over time. Indeed, numerous conceptual papers focus on the issue of describing the CSR states that firms advance through. Yet, related empirical research remains limited and the assumption of steady progression across CSR states remains untested.

Local Search and the Evolution of World Models

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...
