We consider the stochastic response of a nonlinear dynamical system towards a combination of input signals. The response can assume binary values if the state of the system is considered to be the output and the system can make transitions between two states separated by an energetic or entropic barrier. We show how the input-output correspondence can be controlled by an external exponentially correlated dichotomous noise optimizing the logical response which exhibits a maximum at an intermediate value of correlation time. This resonance manifests itself as a "logical" resonance correlation effect and sets the condition for performance of the stochastic system as a logic gate. The role of asymmetry of the dichotomous noise is examined and the results on numerical simulations are correlated with a two-state model using a master equation approach.

Validity between signs and symptoms of sleep bruxism against a validated portable electromyographic device.
J Clin Exp Dent
November 2024
DDS, MS, PhD. Post-Graduate Program in Dentistry (Prosthodontics), Pontifical Catholic University of Rio Grande do Sul (PUCRS), Porto Alegre, Brazil.
Background: Sleep bruxism is a major research area in dentistry today and needs valid clinical means of diagnosis against valid instrumental methods. Purpose: To assess the validity of the most commonly reported sleep bruxism (SB) signs and symptoms in the literature against a polysomnography (PSG) validated portable electromyographic (EMG) device (BiteStrip®).
Material And Methods: Fifty young adults (40 women & 10 men, 18-30 years old) volunteered for the sequential and simultaneous administration of the SB signs and symptoms questionnaire versus the BiteStrip®.
Beyond thinking fast and slow: a Bayesian intuitionist model of clinical reasoning in real-world practice.
Diagnosis (Berl)
December 2024
Department of Medicine, Division of Respiratory & Critical Care Medicine, 59053 National University Hospital, Singapore.
Article Synopsis
- Clinical reasoning is a crucial part of medical education and practice, often examined through the lens of cognitive psychology.
- The dominant theory guiding clinical reasoning has been dual process theory, which splits thinking into fast, intuitive processes and slower, analytical ones, but this model has limitations.
- The authors propose a Bayesian-centric, intuitionist approach to clinical reasoning as a more accurate representation of how decisions are made in real clinical settings, along with strategies to enhance clinical thinking.
Statistical noise in PD-(L)1 inhibitor trials: unraveling the durable-responder effect.
J Clin Epidemiol
November 2024
School of Population Health, The University of Queensland, Brisbane, Queensland, Australia.
Background And Objectives: Programmed-death-1/ligand-1 inhibitors (PD-1/L1is) have emerged as pivotal treatments for many cancers. A notable feature of this class of medicines is the dichotomous response pattern: A small (but clinically relevant) percentage of patients (5%-20%) benefit from deep and durable responses resembling functional cures (durable responders), while most patients experience only a modest or negligible response. Accurately predicting durable responders remains elusive due to the lack of a reliable biomarker.

J Am Acad Audiol
October 2022
Department of Biostatistics, Collaborative Studies Coordinating Center, Gillings School of Global Public Health, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina.
Background: Individual cardiovascular disease (CVD) risk factors (RFs) have been associated with hearing loss (HL). The relationship to aggregate risk is poorly understood and has not been explored in the Hispanic/Latino population.
Purpose: The aim of this study was to characterize the association between aggregate CVD RF burden and hearing among Hispanics/Latinos.
Long-term nighttime aircraft noise exposure and risk of hypertension in a prospective cohort of female nurses.
Int J Hyg Environ Health
January 2025
Department of Environmental Health, Boston University School of Public Health, Boston, MA, USA.
Article Synopsis
- - The study investigates the link between nighttime aircraft noise and hypertension risk using data from the Nurses' Health Studies, focusing on female nurses across the U.S. from 1995 to 2015.
- - Researchers analyzed annual average nighttime noise levels around 90 airports and assessed new hypertension cases among participants who were initially free of the condition.
- - The findings suggest a modest association between exposure to higher levels of aircraft noise (≥45 dB) and increased hypertension risk, indicating that sleep disturbances caused by noise may contribute to cardiovascular issues.
