Systematic analysis of negative and positive feedback loops for robustness and temperature compensation in circadian rhythms

open access: yesnpj Systems Biology and Applications, 2023
Temperature compensation and robustness to biological noise are two key characteristics of the circadian clock. These features allow the circadian pacemaker to maintain a steady oscillation in a wide range of environmental conditions.

Building a Total Internal Reflection Microscope (TIRF) with Active Stabilization (Feedback SMLM)

open access: yesBio-Protocol, 2021
The data quality of high-resolution imaging can be markedly improved with active stabilization, which is based on feedback loops within the microscope that maintain the sample in the same location throughout the experiment.

Nested mechanosensory feedback actively damps visually guided head movements in Drosophila

open access: yeseLife, 2022
Executing agile locomotion requires animals to integrate sensory feedback, often from multiple sources. For example, human gaze is mediated by multiple feedback loops that integrate visual and vestibular information.

A Pair of Smarandachely Isotopic Quasigroups and Loops of the Same Variety [PDF]

open access: yes, 2008
The isotopic invariance or universality of types and varieties of quasigroups and loops described by one or more equivalent identities has been of interest to researchers in loop theory in the recent past.

Transcriptional autoregulatory loops are highly conserved in vertebrate evolution. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: Feedback loops are the simplest building blocks of transcriptional regulatory networks and therefore their behavior in the course of evolution is of prime interest.

Smarandache isotopy of second Smarandache Bol loops [PDF]

open access: yes, 2011
The study of the Smarandache concept in groupoids was initiated by W. B. Vasantha Kandasamy . In her book and first paper on Smarandache concept in loops, she defined a Smarandache loop (S ¡ loop) as a loop with at least a subloop which forms a subgroup ...

Thermohaline feedback loops and Natural Capital

open access: yesScientia Marina, 2001
Human interference now represents an inextricable component of all major ecosystems. Whether this is through top-down overharvesting of ecosystem production or bottom-up alteration (deliberate or inadvertent) of the abiotic conditions, the planet´s ...

An holomorphic study of Smarandache automorphic and cross inverse property loops [PDF]

open access: yes, 2008
By studying the holomorphic structure of automorphic inverse property uasigroups and loops[AIPQ and (AIPL)] and cross inverse property quasigroups and loops[CIPQ and (CIPL)], it is established that the holomorph of a loop is a Smarandache; AIPL, CIPL, K ...

Remarks on the geometry of the feedback loop [PDF]

open access: yes2019 18th European Control Conference (ECC), 2019
Youla parametrization of stabilizing controllers is a fundamental result of control theory. It provides a theoretical and practical tool that renders LFT loops into model matching framework. Based on the geometric techniques introduced in our previous work we have provided a controller blending rule that defines a controller semigroup structure based ...

Evolution of feedback loops in oscillatory systems [PDF]

open access: yes, 2009
Feedback loops are major components of biochemical system. Many systems show multiple such (positive or negative) feedback loops. Nevertheless, very few quantitative analyses that address the question how such multiple feedback loops evolved.
