Add-On Selective Estrogen Receptor Modulators for Methadone Maintenance Treatment

open access: yesFrontiers in Endocrinology, 2021
Methadone maintenance treatment (MMT) remains the cornerstone for the management of opiate abuse. However, MMT can be associated with complex factors, including complications during the tolerance phase, the inability of some patients to maintain ...

Selective Maintenance Policy for a Series-Parallel System Considering Maintenance Priority of Components

open access: yesIEEE Access, 2020
Many systems are required to execute a series of missions with a finite break between any two adjacent missions. In order to improve the reliability of the system completing the next mission successfully, it is necessary to perform maintenance actions on

Fleet-Level Selective Dispatch and Imperfect Maintenance Strategy Optimization Based on Evolutionary Co-Petition Game Theory

open access: yesIEEE Access, 2020
Fleet-level selective dispatch under imperfect maintenance oriented to mission reliability is a practical, multi-level maintenance strategy decision problem that becomes highly difficult since the number of potential maintenance strategies dramatically ...

Selective endocytosis controls slit diaphragm maintenance and dynamics in Drosophila nephrocytes

open access: yeseLife, 2022
The kidneys generate about 180 l of primary urine per day by filtration of plasma. An essential part of the filtration barrier is the slit diaphragm, a multiprotein complex containing nephrin as major component.

Mission Reliability-Oriented Selective Maintenance Optimization for Intelligent Multistate Manufacturing Systems With Uncertain Maintenance Quality

open access: yesIEEE Access, 2019
Selective maintenance is widely used as a reliability-centered maintenance strategy due to the limited maintenance resources. However, existing selective maintenance studies only consider basic reliability, which cannot systematically describe the ...

Shortening day length as a previously unrecognized selective pressure for early breeding in a bird with long parental care [PDF]

open access: yes, 2014
Several different selective pressures have been suggested to explain an intense competition for early return to breeding grounds in birds. In this study we hypothesized that shortening day length during summer months may constitute additional ...

On the Explicit Function of Life within a Physical Universe

open access: yesPhilosophies, 2021
To describe the meaning of functionality in a universe before life evolved, existing etiological and systemic accounts of function are evaluated. Since the theory of function is only applicable in context with living beings and artifacts used by living ...
