Two Determinants of Dynamic Adaptive Learning for Magnitudes and Probabilities.

Humans face a dynamic world that requires them to constantly update their knowledge. Each observation should influence their knowledge to a varying degree depending on whether it arises from a stochastic fluctuation or an environmental change. Thus, humans should dynamically adapt their learning rate based on each observation.

Gated recurrence enables simple and accurate sequence prediction in stochastic, changing, and structured environments.

From decision making to perception to language, predicting what is coming next is crucial. It is also challenging in stochastic, changing, and structured environments; yet the brain makes accurate predictions in many situations. What computational architecture could enable this feat? Bayesian inference makes optimal predictions but is prohibitively difficult to compute.

Initial Reintroduction of the Aye-Aye (Daubentonia madagascariensis) in Anjajavy Reserve, Northwestern Madagascar.

Madagascar's biodiversity is imperiled by habitat loss and degradation. Furthermore, species may be locally extirpated due to targeted hunting or disease. Translocating at-risk individuals to areas devoid of the species may be an effective conservation intervention.

Evaluation of a Model of Long-Term Middle Ear Catheterization for Repeat Infusion Administration and Cochlear Hair Cell Injury in Guinea Pigs.

Middle ear administration has numerous applications, including antibiotherapy and gene therapy, and is increasingly used to target the auditory and vestibular systems. In animal studies, investigating repeated exposure that mimics clinical dosing regimens has remained a challenge due to the lack of suitable models. Intratympanic injections are not suitable for long-term studies due to the increased risk related to tympanic membrane rupture or scarring and repeat anesthesia events.

Factors associated with unfavorable outcome in a multicenter audit of 100 infective endocarditis.

We aimed to identify factors associated with unfavorable outcome in patients treated for infective endocarditis (IE), with a focus on departure from European guidelines. We conducted a retrospective audit of all adult patients treated for endocarditis during a 1-year period across a regional network of nine care centers in the south-east of France. Medical records were reviewed regarding patient and infection characteristics, antibiotic therapy, outcome, and compliance to the European Society of Cardiology guidelines.
