Long-term pan evaporation observations as a resource to understand the water cycle trend: case studies from Australia

Acceleration of the global water cycle over recent decades remains uncertain because of the high inter-annual variability of its components. Observations of pan evaporation (E-pan), a proxy of potential evapotranspiration (ETp), may help to identify trends ...

Above- and belowground linkages in Sphagnum peatland: climate warming affects plant-microbial interactions

Alexandre Buttler, Edward Mitchell, Vincent Eric Jules Jassey

Peatlands contain approximately one third of all soil organic carbon (SOC). Warming can alter above- and belowground linkages that regulate soil organic carbon dynamics and C-balance in peatlands. Here we examine the multiyear impact of in situ experimenta ...

Interference Channels with Bursty Traffic and Delayed Feedback

Suhas Diggavi, I-Hsiang Wang

In this paper we study interference management in wireless networks with bursty user traffic. In each time slot, whether a user is on or off for transmission is governed by its own Bernoulli random state. At each transmitter, the states of activities of ot ...

Tunable reporter signal production in feedback-uncoupled arsenic bioreporters

Vassily Hatzimanikatis, Jan Roelof van der Meer

Escherichia coli-based bioreporters for arsenic detection are typically based on the natural feedback loop that controls ars operon transcription. Feedback loops are known to show a wide range linear response to the detriment of the overall amplification o ...

Post-translational regulation enables robust p53 regulation

Ali H. Sayed

The tumor suppressor protein p53 plays important roles in DNA damage repair, cell cycle arrest and apoptosis. Due to its critical functions, the level of p53 is tightly regulated by a negative feedback mechanism to increase its tolerance towards fluctuatio ...

Force feedback facilitates multisensory integration during robotic tool use

Olaf Blanke, Hannes Bleuler, Giulio Rognini, Jane Aspell, Michiel van Elk, Ali Sengül

The present study investigated the effects of force feedback in relation to tool use on the multisensory integration of visuo-tactile information. Participants learned to control a robotic tool through a surgical robotic interface. Following tool-use train ...

On Two Unicast Wireless Networks with Destination-to-Source Feedback

I-Hsiang Wang

In this paper we study the role of feedback in layered two unicast wireless networks with arbitrary number of nodes and connectivity. The feedback model allows destinations to feedback their received signals to their respective sources. In the case of line ...

Towards multimodal Haptics for teleoperation: Design of a Tactile Thermal Display

Hannes Bleuler, Giulio Rognini, Laura Santos Carreras

Surgical robotics is among the most challenging applications of motion control. Present and future systems are essentially master-slave systems. Our work focuses on force-feedback and haptic interfaces. In this context, we study multimodal haptic interface ...

A synthetic review of feedbacks and drivers of shrub encroachment in arid grasslands

Paolo d'Odorico

Many arid grasslands around the world are affected by woody plant encroachment and by the replacement of a relatively continuous grass cover with shrub patches bordered by bare soil. This shift in plant community composition is often abrupt in space and ti ...

Temporally Coherent Completion of Dynamic Shapes

Mark Pauly, Hao Li

We present a novel shape completion technique for creating temporally coherent watertight surfaces from real-time captured dynamic performances. Because of occlusions and low surface albedo, scanned mesh sequences typically exhibit large holes that persist ...
