- Comparative analysis of multiple genomes in a phylogenetic framework dramatically improves the precision and sensitivity of evolutionary inference, producing more robust results than single-genome analyses can provide. The genomes of 12 Drosophila species, ten of which are presented here for the first time (sechellia, simulans, yakuba, erecta, ananassae, persimilis, willistoni, mojavensis, virilis and grimshawi), illustrate how rates and patterns of sequence divergence across taxa can illuminate evolutionary processes on a genomic scale. These genome sequences augment the formidable genetic tools that have made Drosophila melanogaster a pre-eminent model for animal genetics, and will further catalyse fundamental research on mechanisms of development, cell biology, genetics, disease, neurobiology, behaviour, physiology and evolution. Despite remarkable similarities among these Drosophila species, we identified many putatively non-neutral changes in protein-coding genes, non-coding RNA genes, and cis-regulatory regions. These may prove to underlie differences in the ecology and behaviour of these diverse species.

Book chapter (peer-reviewed)abstract
- Current transportation systems face great challenges due to the increasing mobility. Traffic accidents, congestion, air pollution, etc., are all calling for new methods to improve the transportation system. With the US legislation in progress over vehicle communications and EU’s finalization of the basic set of standards over cooperative intelligent transportation systems (C-ITS), vehicular ad hoc network (VANET) based applications are expected to address those challenges and provide solutions for a safer, more efficient and sustainable future intelligent transportation systems (ITS). In this chapter, transportation challenges are firstly summarized in respect of safety, efficiency, environmental threat, etc. A brief introduction of the VANET is discussed along with state of the art of VANET-based applications. Based on the current progress and the development trend of VANET, a number of new features of future VANET are identified, together with a set of potential future ITS applications. The on-going research and field operational test projects, which are the major enabling efforts for the future VANET-based C-ITS, are presented. The chapter is of great interest to readers working within ITS for current development status and future trend within the C-ITS area. It is also of interest to general public for an overview of the VANET enabled future transportation system. © Springer International Publishing Switzerland 2015.

Book chapter (peer-reviewed)abstract
- Telematics is an interdisciplinary technology that combines telecommunications, vehicular technologies, road transportation, road safety, electrical engineering, and computer science to provide applications and services for the purpose of comfort and safety enhancement. From the timing point of view, the driving safety can be classified into two domains: (1) active safety and (2) passive safety. Passive safety systems are used to reduce damage and protect passengers and drivers when an accident occurs. Common passive safety systems include airbags, seatbelts, whiplash injury lessening systems, and energy absorbing steering column. Active safety systems are used to prevent accidents before they occur. An example of active safety system is the collision warning/avoidance system. It basically collects/detects neighboring vehicles' motion states to compute potential collision between vehicles. Based on future technology, cooperative active safety systems emerge. Vehicles can exchange their information between each other through wireless communication [1], for example, over a vehicular ad hoc network (VANET), for cooperative purposes such as collision warning/avoidance. In a project named smart intersection, a collision avoidance system based on the concept of active safety was developed by Ford and the US government [2]. The system collects a vehicle's information like Global Positioning System (GPS) coordinates, velocity, and heading and delivers it through wireless communication to other vehicles in order to prevent accidents and congestion before vehicles arrive to an intersection. To understand the details of cooperative collision warning (CCW), this chapter exposes main factors that affect the accuracy of CCW, challenges of CCW, communication techniques for cooperative safety, and collision prediction techniques. CCW systems are also introduced in detail. Moreover, we present some existing safety-related techniques and systems that are developed by automobile manufacturers. © The Institution of Engineering and Technology 2015

Poster : Adaptive Wavelength Adjustment (AWLA) for Cooperative Speed Harmonization
- 2014

In: 2014 IEEE Vehicular Networking Conference (VNC). - Piscataway, NJ : IEEE Press. - 9781479976607 ; , s. 113-114, s. 113-114

Conference paper (peer-reviewed)abstract
- Traffic merge on express-ways creates bottlenecks for traffic flow that potentially lead to traffic jams, especially in dense traffic. Cooperative speed harmonization (CSH), where vehicles are grouped and associated to virtual speed waves for group-wise joining at intersections, is proven to be efficient for on-ramp traffic merge. Based on CSH and considering variations of traffic density from joining roads, an adaptive wavelength adjustment (AWLA) mechanism is proposed in this paper. AWLA extends CSH by dynamically adjusting the length of segments in virtual waves according to the traffic densities of the joining roads. Therefore, roads with denser traffic may have larger segments to carry more vehicles through the intersection, which may improve the overall performance. Simulation results have shown that AWLA can achieve lower CO2 emissions and shorter travel time compared to CSH with static segment settings.
