AI Article Synopsis
- The authors conducted 5 experiments examining the cognitive costs of repeating the same or similar responses in dual-task scenarios.
- They found that changing the cognitive representation of a response led to costs, while keeping it the same resulted in benefits.
- Furthermore, compatibility costs arose when cognitive representations of similar responses differed, but benefits occurred when they matched, highlighting a mechanism of action selection in cognitive processing.
Article Abstract
In 5 experiments, the authors investigated the costs associated with repeating the same or a similar response in a dual-task setting. Using a psychological refractory period paradigm, they obtained response-repetition costs when the cognitive representation of a specific response (i.e., the category-response mapping) changed (Experiment 1) but benefits when it did not change (Experiment 2). The analogous pattern of results was found for conceptually similar (i.e. compatible) responses. Response-response compatibility costs occurred when the cognitive representations of the compatible responses were different (Experiments 3A & 3B), but compatibility benefits occurred when they were the same (Experiment 4). The authors interpret the costs of repeating an identical or compatible response in terms of a general mechanism of action selection that involves coding the task-specific meaning of a response.

According to ideomotor accounts, actions are cognitively represented by their sensory effects. The response-effect compatibility (R-E compatibility) paradigm investigates this notion by presenting predictable effect stimuli that are produced by the response ("response effects"). The R-E compatibility effect denotes the finding of better performance in R-E compatible conditions than in incompatible conditions, suggesting that anticipation of the effect stimulus primes the response.

Sensitivity and linearity are two key parameters of flexible strain sensors. Although the introduction of microstructures (, channel crack inspired by the geometry of the spider's slit organ) can effectively improve the sensitivity, the sudden breakage of the conductive path in turn leads to poor linearity. In practical applications, in order to achieve precise detection of subtle strains, high sensitivity and high linearity are required simultaneously.

Purpose: Adverse outcome pathways (AOPs) provide a modular framework for describing sequences of biological key events (KEs) and key event relationships (KERs) across levels of biological organization. Empirical evidence across KERs can support construction of quantified AOPs (qAOPs). Using an example AOP of energy deposition from ionizing radiation onto DNA leading to lung cancer incidence, we investigate the feasibility of quantifying data from KERs supported by all types of stressors.

Flexible strain sensors have a wide range of applications in biomedical science, aerospace industry, portable devices, precise manufacturing, etc. However, the manufacturing processes of most flexible strain sensors previously reported have usually required high manufacturing costs and harsh experimental conditions. Besides, research interests are often focused on improving a single attribute parameter while ignoring others.

In this paper, a pilot production process for mesenchymal stem/stromal freeze-dried secretome was performed in a validated good manufacturing practice (GMP)-compliant cell factory. Secretome was purified from culture supernatants by ultrafiltration, added to cryoprotectant, lyophilized and characterized. We obtained a freeze-dried, "ready-off-the-shelf" and free soluble powder containing extracellular vesicles and proteins.
