We establish two results under which the topology of a hyperbolic set constrains ambient dynamics. First if Λ is a compact, transitive, expanding hyperbolic attractor of codimension 1 for some diffeomorphism, then Λ is a union of transitive, expanding attractors (or contracting repellers) of codimension 1 for any diffeomorphism such that Λ is hyperbolic. Secondly, if Λ is a nonwandering, locall...

BACKGROUND Lepidoptera insects have a novel development process comprising several metamorphic stages during their life cycle compared with vertebrate animals. Unlike most Lepidoptera insects that live on nectar during the adult stage, the Bombyx mori silkworm adults do not eat anything and die after egg-laying. In addition, the midguts of Lepidoptera insects produce antimicrobial proteins duri...

Smallwood (2013) made important contributions to the science of mind wandering by distinguishing between 2 aspects of the mind-wandering experience: (a) how the mind wanders, which entails the process of maintaining the continuity of a mind-wandering episode, and (b) why the mind wanders, which refers to those mechanisms that lead to the occurrence of a mind-wandering episode. This new process-...

Mind-wandering is the focus of extensive investigation, yet until recently there has been no validated scale to directly measure trait levels of task-unrelated thought. Scales commonly used to assess mind-wandering lack face validity, measuring related constructs such as daydreaming or behavioral errors. Here we report four studies validating a Mind-Wandering Questionnaire (MWQ) across college,...

OBJECTIVES To explore the extent of and factors associated with male residents who change wandering status post nursing home admission. DESIGN Longitudinal design with secondary data analyses. Admissions over a 4-year period were examined using repeat assessments with the Minimum Data Set (MDS) to formulate a model understanding the development of wandering behavior. SETTING One hundred thi...

Article history: Received 15 September 2015 Received in revised form 14 December 2015 Accepted 18 December 2015 Available online 29 December 2015 Mind-wandering is associated with adverse effects on life satisfaction. However, the potential mechanism that might explain the relationship between mind-wandering and life satisfaction is unclear. Furthermore, although attention problems are widespre...

Wandering is a typical feature of wing-tip vortices and it consists in random fluctuations of the vortex core. Consequently, vortices measured by static measuring techniques appear to be more diffuse than in reality, so that a correction method is needed. In the present paper statistical simulations of the wandering of a Lamb-Oseen vortex are first performed by representing the vortex core loca...

Although mind wandering occupies a large proportion of our waking life, its neural basis and relation to ongoing behavior remain controversial. We report an fMRI study that used experience sampling to provide an online measure of mind wandering during a concurrent task. Analyses focused on the interval of time immediately preceding experience sampling probes demonstrate activation of default ne...
