Durable Digital Objects Rather Than Digital Preservation [PDF]

open access: yes, 2008
Long-term digital preservation is not the best available objective. Instead, what information producers and consumers almost surely want is a universe of durable digital objects—documents and programs that will be as accessible and useful a century from

Screening for Social Determinants of Health in Patients with Systemic Lupus Erythematosus: A Point‐of‐Care Feasibility Study

open access: yesArthritis Care &Research, Accepted Article.
Objectives Social determinants of health (SDoH) can impact outcomes but are not routinely screened for in US outpatient rheumatology clinics. This study determined the feasibility of routine point‐of‐care SDoH screening among patients with systemic lupus erythematosus (SLE), and associated barriers and facilitators at the physician, care team, and ...

Measures of Durability of Resistance [PDF]

open access: yesPhytopathology®, 2003
Conventional models for the durability of resistant cultivars focus on the dynamics of the frequency of resistance genes. This leads to a definition of the durability of resistance as the time from introduction of the cultivar to the time when the frequency of the virulence gene reaches a preset threshold.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

open access: yesAdvanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Hydrogel‐Based Capacitive Sensor Model for Ammonium Monitoring in Aquaculture

open access: yesAdvanced Engineering Materials, EarlyView.
Traditional techniques for monitoring aquaculture water quality, particularly ammonium levels, harm fish. This work presents a novel capacitive sensor with an ionic hydrogel transducer to monitor ammonium concentration in real time based on the ammonium‐induced hydrogel dissociation and osmotic pressure. Monitoring aquaculture water quality, especially
