We set up the electromagnetic system and its plane-wave solutions with the associated slowness and wave surfaces. We treat the Cauchy initial-value problem for the electric vector and make explicit the quantities necessary for numerical evaluation. We use the HerglotzPetrovskii representation as an integral around loops which, for each position and time form the intersection of a plane in the s...

Most of the serious handicaps of childhood present long before the age of 3 years. In the 3 to 5 year age group the commonest cause for concern is that the child is progessing more slowly than his peers, either in acquisition of language, motor coordination, or in all aspects of development. The purpose of this paper is firstly to review the concept of 'slowness', and then to discuss the paedia...

Understanding the guiding principles of sensory coding strategies is a main goal in computational neuroscience. Among others, the principles of predictive coding and slowness appear to capture aspects of sensory processing. Predictive coding postulates that sensory systems are adapted to the structure of their input signals such that information about future inputs is encoded. Slow feature anal...

In an important paper Hinton and Nowlan demonstrate the Baldwin e ect in a simple Genetic Algorithm The ability of the phenotype to adapt coupled with the evolu tionary process allows behavioural goals to become over time genetically speci ed this seems Lamarckian but is not In that paper as a subsidiary point the slowness of xa tion of the last few goals is commented on and a later paper by Be...

The regional seismic travel time (RSTT) model and software were developed to improve travel-time prediction accuracy by accounting for three-dimensional crust upper mantle structure. Travel-time uncertainty estimates are used in the process of associating phases events accurately calculate location bounds (i.e. event error ellipses). We on current distance-dependent parameterization RSTT using ...

BACKGROUND Neuronal degeneration and dopamine loss in the preclinical phase of Parkinson disease may produce subtle complaints before clinically recognizable symptoms emerge. OBJECTIVE To examine whether subjective complaints of stiffness, slowness, tremors, or postural imbalance in persons without clinical signs of parkinsonism are related to an increased risk of future Parkinson disease. ...

In the hours following the 2011 Honshu event, and as part of tsunami warning procedures at the Laboratoire de Géophysique in Papeete, Tahiti, the seismic source of the event was analyzed using a number of real-time procedures. The ultra-long period mantle magnitude algorithm suggests a static moment of 4.1 9 10 dyn cm, not significantly different from the National Earthquake Information Center ...

Slow Technology is an opportunity to create reflective, mesmerizing and tangible experiences of temporality in relation to human perspectives and situated experiences. Hallnas and Redstrom [1] proposed the concepts of ‘reflective’ and ‘time’ technology as part of their design philosophy of slowness; this paper focuses on these concepts in reference to a specific time based artwork that explores...
