Observing Behavior: Effects of Rate and Magnitude of Primary Reinforcement

open access: yes, 2002
Four experiments examined the free-operant observing behavior of rats. In Experiment 1, observing was a bitonic function of random-ratio schedule requirements for the primary reinforcer.

Elastic-viscoplastic behavior of filament winding CFRP: experimental investigation and multiscale analysis

open access: yesMechanical Engineering Journal
In this study, tensile properties including material nonlinearity (viscoplasticity) of carbon fiber-reinforced plastics manufactured by the filament winding method (FW-CFRPs) are experimentally investigated, and numerically analyzed using a three-scale ...

Theoretical Analysis and Experimental Evaluation of Road Dynamic Behavior on Different Subgrades

open access: yesAdvances in Civil Engineering, 2019
The dynamic characteristics of a road on a subgrade filled with different materials under traffic loads are studied. An elastic double-layer plate model on a viscoelastic subgrade is established to describe the dynamic behavior of the road.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Divided stimulus control: A replication and a quantitative model

open access: yes, 2010
Four pigeons were trained on a conditional discrimination. The conditional stimuli were compounds of pairs of stimuli from two different dimensions, fast versus slow cycles of red or green stimuli, and shortversus long-duration presentations of these ...

Experimental Behavior and Analysis of Hybrid Low-High Strength Reinforced Concrete Columns

open access: yesJournal of Materials and Engineering Structures, 2020
In this paper, the behavior of hybrid short columns made from low strength reinforced concrete core and an outer skin made from high strength concrete was studied.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

EMERGENT CONDITIONAL RELATIONS IN A GO/NO-GO PROCEDURE: FIGURE-GROUND AND STIMULUS-POSITION COMPOUND RELATIONS

open access: yes, 2009
Past research has demonstrated emergent conditional relations using a go/no-go procedure with pairs of figures displayed side-by-side on a computer screen. The present Study sought to extend applications Of this procedure.
