Neurophysiological underpinnings of an intensive protocol for upper limb motor recovery in subacute and chronic stroke patients

Silvestro Micera

ABS T R A C T BACKGROUND: Upper limb (UL) motor impairment following stroke is a leading cause of functional limitations in activities of daily living. Robot-assisted therapy supports rehabilitation, but how its efficacy and the underlying neural mechanism ...

Cryptographic Administration for Secure Group Messaging

Serge Vaudenay, Daniel Patrick Collins

Many real-world group messaging systems delegate group administration to the application level, failing to provide formal guarantees related to group membership. Taking a cryptographic approach to group administration can prevent both implementation and pr ...

Challenges and approaches in bridging the biomimicry gap in biohybrid systems of fish and robots

Vaios Papaspyros

As the field of ethology advances, especially over the past two decades, the role of animal-robot interaction tools has increasingly become essential. This importance arises from the need for controlled, repetitive, repeatable, and long-duration experiment ...

‘Ecological concerns weren’t the main reason why I took the bus, that association only came afterwards’: on shifts in meanings of everyday mobility

Livia Bianca Fritz, Franziska Meinherz

Reducing the modal share of car travel in commuting implies challenging meanings of everyday mobility that tie commuting to driving. Existing research has focussed on describing ways in which everyday mobility is meaningful. However, why shifts in meanings ...

Discrete-Choice Mining of Social Processes

Victor Kristof

Poor decisions and selfish behaviors give rise to seemingly intractable global problems, such as the lack of transparency in democratic processes, the spread of conspiracy theories, and the rise in greenhouse gas emissions. However, people are more predict ...

A Laplacian approach to stubborn agents and their role in opinion formation on influence networks

Melvyn Sandy Tyloo

Within the framework of a simple model for social influence, the Taylor model, we analytically investigate the role of stubborn agents in the overall opinion dynamics of networked systems. Similar to zealots, stubborn agents are biased towards a certain op ...

How single neuron properties shape chaotic dynamics and signal transmission in random neural networks

Wulfram Gerstner, Tilo Schwalger, Samuel Pavio Muscinelli

While most models of randomly connected neural networks assume single-neuron models with simple dynamics, neurons in the brain exhibit complex intrinsic dynamics over multiple timescales. We analyze how the dynamical properties of single neurons and recurr ...

Bartering Books to Beers: a Recommender System for Exchange Platforms

Michele Catasta, Jérémie Rappaz, Maria-Luiza Vladarean

Bartering is a timeless practice that is becoming increasingly popular on the Web. Recommending trades for an online bartering platform shares many similarities with traditional approaches to recommendation, in particular the need to model the preferences ...

A Motion Capture Study to Measure the Feeling of Synchrony in Romantic Couples and in Professional Musicians

Pierre Magistretti, Joan Llobera Mahy, Delphine Preissmann

The feeling of synchrony is fundamental for most social activities and prosocial behaviors. However, little is known about the behavioral correlates of this feeling and its modulation by intergroup differences. We previously showed that the subjective feel ...

Undergraduate group projects: Challenges and learning experiences

Roland John Tormey, Siara Ruth Isaac

Working in groups and managing projects are important professional skills for engineers, and there is a growing demand to teach and assess such skills. But what should be taught and when? Tuckman’s famous “stages of development of performing groups” provid ...

Mechanosensory interactions drive collective behaviour in Drosophila

Dario Floreano, Pavan P Ramdya, Pawel Lichocki

Collective behaviour enhances environmental sensing and decision-making in groups of animals. Experimental and theoretical investigations of schooling fish, flocking birds and human crowds have demonstrated that simple interactions between individuals can ...

MOOC Learning in Spontaneous Study Groups: Does Synchronously Watching Videos Make a Difference?

Pierre Dillenbourg, Guillaume Zufferey, Himanshu Verma, Nan Li, Afroditi Skevi

Study groups are common approaches for students to study together at schools. However, little is known about how this approach is suited to MOOC based learning, where learners watch and discuss MOOC lecture videos in a collaborative manner. Watching MOOCs ...

Computational Modeling of Face-to-Face Social Interaction Using Nonverbal Behavioral Cues

Dinesh Babu Jayagopi

The computational modeling of face-to-face interactions using nonverbal behavioral cues is an emerging and relevant problem in social computing. Studying face-to-face interactions in small groups helps in understanding the basic processes of individual and ...

Simple Monte Carlo model for crowd dynamics

Francesco Piazza

In this paper, we introduce a simple Monte Carlo method for simulating the dynamics of a crowd. Within our model a collection of hard-disk agents is subjected to a series of two-stage steps, implying (i) the displacement of one specific agent followed by ( ...

Agent-Based Routing in Queueing Systems

Olivier Gallay

Waiting time in any network is often a costly and hence a bad experience. Therefore, to avoid jamming regions becomes essential in the optimization of traffic flows. In this regard, the conception and the control of complex networks supporting flows of uni ...

From Set Membership to Group Membership: A Separation of Concerns

André Schiper

We revisit the well-known group membership problem and show how it can be considered a special case of a simple problem, the set membership problem. In the set membership problem, processes maintain a set whose elements are drawn from an arbitrary universe ...
