22 Jun 2015TL;DR: A method to control ultrasonic waves on a beam, allowing to obtain a Multi-touch ultrasonic tactile stimulation in two points, to give the sensation to two fingers, from two piezoelectric transducers is presented.
Abstract: This paper presents a method to control ultrasonic waves on a beam, allowing to obtain a Multi-touch ultrasonic tactile stimulation in two points, to give the sensation to two fingers, from two piezoelectric transducers. The multi-modal approach and the vector control method are used to regulate the vibration amplitude, in order to modulate the friction coefficient with the fingers. An analytical modelling is presented, with experimental validation. Finally a psychophysical experiment shows that a multi-touch ultrasonic tactile stimulation is possible.

TL;DR: The genetic component of olfactory learning was investigated using proboscis extension conditioning to record individual performance, and a patriline-level analysis to separate the variance in learning performance into its different components.
Abstract: Genetically determined differences among honeybee workers are known to contribute to task specialisation. To investigate the genetic component of olfactory learning we used proboscis extension conditioning to record individual performance, and a patriline-level analysis to separate the variance in learning performance into its different components. We found that the among-patriline within-colony component (solely genetic) explained 11.2% of the variance in acquisition performance and 6.5% of the variance in resistance to extinction. While environmental effects appeared to be the main source of variation, our results confirm that olfactory learning has a significant genetic basis. If colonies benefit from genetic differences among workers in task expression thresholds, colonies might also benefit from genetic differences in cognitive performance among workers by influencing task performance.

TL;DR: In this paper, the authors used a Lagrangian framework with three-dimensional velocity fields from two versions of the Regional Ocean Modeling System (ROMS) to study the deep-bottom connectivity between submarine canyons and to compare their influence on the particle transport.
Abstract: . Marine biophysical models can be used to explore the displacement
of individuals in and between submarine canyons. Mostly, the studies focus
on the shallow hydrodynamics in or around a single canyon. In the
northwestern Mediterranean Sea, knowledge of the deep-sea circulation
and its spatial variability in three contiguous submarine canyons is
limited. We used a Lagrangian framework with three-dimensional velocity
fields from two versions of the Regional Ocean Modeling System (ROMS) to
study the deep-bottom connectivity between submarine canyons and to compare
their influence on the particle transport. From a biological point of view,
the particles represented eggs and larvae spawned by the deep-sea commercial
shrimp Aristeus antennatus along the continental slope in summer. The passive particles mainly
followed a southwest drift along the continental slope and drifted less than
200 km considering a pelagic larval duration (PLD) of 31 d. Two of the
submarine canyons were connected by more than 27 % of particles if they were
released at sea bottom depths above 600 m. The vertical advection of
particles depended on the depth where particles were released and the
circulation influenced by the morphology of each submarine canyon.
Therefore, the impact of contiguous submarine canyons on particle transport
should be studied on a case-by-case basis and not be generalized. Because
the flows were strongly influenced by the bottom topography, the
hydrodynamic model with finer bathymetric resolution data, a less smoothed
bottom topography, and finer sigma-layer resolution near the bottom should
give more accurate simulations of near-bottom passive drift. Those results
propose that the physical model parameterization and discretization have to
be considered for improving connectivity studies of deep-sea species.

TL;DR: The research analyses how Augmented Reality associated to video may affect collaborative design and multimodal interactions and proposes a coding method usable beyond design in a wide range of collaborative activities to underline how they are affected by technology and other situational constraints.
Abstract: Motivation -- To analyse how Augmented Reality associated to video may affect collaborative design and multimodal interactions.Research approach -- An exploratory study that aims to compare 2 pairs of last year students in co-presence with 1 distant pair. Each pair had to solve an architectural design problem. Collected video has been coded with a systematic method of protocol analysis.Findings/Design -- When using an AR desktop-based CAD, distance may not affect the design process itself whereas it may affect how the process is distributed across the various modalities of collaboration. Furthermore, collaborating and architectural experiences influence collaboration and/or design.Research limitations/Implications -- Only 3 pairs of students participated in the study resulting in 12 h of video protocol, which limits generalisation of the findings.Originality/Value -- The research makes a contribution in providing a detailed view on how external (e.g. situation, technology) and individual factors may affect the activity of collaborative design. Furthermore, we propose a coding method usable beyond design in a wide range of collaborative activities to underline how they are affected by technology and other situational constraints.Take away message -- Technology constraints as well as personnal characteristics of designers result in designing with specific forms of multimodal collaboration.
