Subthreshold-seeking local search
Theoretical Computer Science, 2006 AbstractAlgorithms for parameter optimization display subthreshold-seeking behavior when the majority of the points that the algorithm samples have an evaluation less than some target threshold. We first analyze a simple “subthreshold-seeker” algorithm.

Detection of subthreshold depression and subthreshold anxiety in the elderly
International Journal of Geriatric Psychiatry, 1999 To assess the ability of screening instruments to detect subthreshold depression or subthreshold anxiety and to make suggestions for the improvement of instrument performance.Group definition relied on the presence or absence of major psychiatric disorders or of subthreshold disorders (Composite International Diagnostic Interview).A community-based ...

A general subthreshold MOS translinear theorem [PDF]
ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI (Cat. No.99CH36349), 2003 This paper outlines the conditions under which the Translinear Principle can be fully exploited for MOS transistors operating in subthreshold. Due to the exponential nature of subthreshold MOS transistors the Translinear principle applies immediately as long as the Source-to-Bulk voltages are made equal to zero (or constant).

Adult Autism Subthreshold Spectrum (AdAS Spectrum): Validation of a questionnaire investigating subthreshold autism spectrum. [PDF]
Comprehensive Psychiatry, 2017 AIM Increasing literature has shown the usefulness of a dimensional approach to autism. The present study aimed to determine the psychometric properties of the Adult Autism Subthreshold Spectrum (AdAS Spectrum), a new questionnaire specifically tailored ...

Resonant spike propagation in coupled neurons with subthreshold activity [PDF]
, 2008 Màster en Biofísica, curs 2006-2007Chemical coupling between neurons is only active when the presynaptic neuron is firing, and thus it does not allow for the propagation of subthreshold activity.

On the transience or stability of subthreshold psychopathology [PDF]
Scientific Reports, 2021 AbstractSymptoms of psychopathology lie on a continuum ranging from mental health to psychiatric disorders. Although much research has focused on progression along this continuum, for most individuals, subthreshold symptoms do not escalate into full-blown disorders.

An empirical investigation of definitions of subthreshold posttraumatic stress disorder
Journal of Traumatic Stress, 2023 Subthreshold posttraumatic stress disorder (PTSD) has long been recognized as an important construct that identifies a subgroup of individuals who report significant PTSD symptoms and associated disability but do not endorse enough symptoms to meet the ...

Probing subthreshold dynamics of hippocampal neurons by pulsed optogenetics
Science, 2022 Understanding how excitatory (E) and inhibitory (I) inputs are integrated by neurons requires monitoring their subthreshold behavior. We probed the subthreshold dynamics using optogenetic depolarizing pulses in hippocampal neuronal assemblies in freely ...
