The widely-recognized essential features of the emerging 5G network compared with 4G networks include: 1000 times larger system capacity, 1/1000 power consumption, 10 Gbps peak rate and 1 ms end-to-end delay, while the innovation in transmission technologies is the basis in achieving this goal. The research carried out in this project can be divided into three areas: 1) New transmission architecture and protocol design for 5G networks 2) Green-transmission enabled 5G network technologies, 3) Advanced spectrum-sharing and smart transmission strategies in 5G networks. The proposed architectures, protocols, algorithms, techniques, and schemes are validated and evaluated through simulation platform and demonstration systems. Through this project, we expect to not only build theoretical foundations for 5G networks, but also to provide high-quality training opportunities for graduate students and engineers both in Finnish and Chinese Universities/Research Institutes.

Due the rapid increase in mobile and machine type data traffic the densities of networks are growing fast and deployment of local Ultra Dense Networks (UDNs) is seen as a viable solution in 5G framework. In this project we will consider the fundamental 5G challenges including 1) development of connectivity and control structures for high carrier frequency systems, 2) design of new low-latency, lowenergy 5G radio interface, 3) design of novel cooperative communication, beamforming and massive MIMO principles, 4) development of resource allocation principles for layered UDN deployment and 5) design principles enabling energy efficient UDN. We study these topics especially from indoor connectivity and machine type communication perspectives.

PET imaging with 18F-FDG has been shown to be sensitive and cost-effective for evaluating cancer patients at various phases such as diagnosis, staging, and therapy assessment. Typically, 18F-FDG is administrated to patients intravenously. 18F-FDG venous injection is simple and useful in clinical routine, but venous access cannot be established in all patients, such as cancer patients with a history of extensive chemotherapy. The primary purpose of the project was to investigate the dynamic process of 18F-FDG distribution after oral administration in order to determine the optimal imaging acquisition time in human subjects. Furthermore, we are planning to investigate the absorption function of small intestine by measuring the dynamic parameter of FDG after oral administration.

Carotid artery plaques are a leading cause of ischemic stroke, and carotid endarterectomy (CEA) is one of the major treatment approaches for this disease. Changes in cerebral metabolism following CEA remain unclear. The present study aimed to evaluate the effect of cerebral ammonia metabolism following CEA using 13N labeled ammonia positron emission tomography (PET) in humans. This is clinical study in human subjects. This is an international collaboration project. Since Turku PET Centre has very strong PET research experiences, we provides the research protocols to China. Partners in China performed clinical investigations based on our protocols. Furthermore, we performed data analysis and manuscript writing.

Vascular adhesion protein-1 (VAP-1) is an adhesion molecule and involved in leukocyte rolling, adhesion, and transmigration from the blood into sites of inflammation, which is important for the pathogenesis of atherosclerosis. VAP-1 was found and identified in Turku by Prof. Sirpa Jalkanen. In this study, we planed to investigate the relationship soluble VAP-1(sVAP-1) in serum with cardiovascular factors based on Chinese population. This is an internation collaboration project. Finland provides technical supports and VAP-1 antibodies to China. Parters in China performed population study.

The purpose of research is to develop and validate a novel system for quantitative assessment of multi-organ tissue-perfusion using a dedicated cyclotron-produced, short-lived nuclei of 15O and PET for non-invasive human and small animal studies. This system is to overcome organ-specific problems. The goal is to establish a standard package for quantitative assessment of tissue perfusion, involving ICT-based multi-modality image processing techniques.

Mitochondria,as "energy factories", are responsible for creating more than 90% of the energy needed by the body to sustain life. Mitochondrial disease is a group of disorders cuased by dysfunctional mitochondria. About 1 in 4,000 children will develope this disease by the age of 10 years.Currently there is no specific method to detect this disorder clinically. This study is designated to develop a novel PET tracer for imaging mitochondrial membrane potential (MMP), which is a key inditor for moniting mitochondrial function.This is an international collaboration project with China: one researcher comes from China and part of project will be performed in China (synthesis of precursor).

As of the time 14:46, March 11, 2011, Tohoku, Japan was hit by a massive earthquake. The epicentre of the earthquake was located to be undersea off the coast of Japan, and the magnitude-level was 9.0. The first earthquake also triggered a series of subsequent big earthquakes. Altogether, these earthquakes caused huge trembling on the Japanese mainland, reaching magnitude-level 7 at Kurihara City in the Miyagi prefecture, and Level 6 across many places in Tohoku. Following these huge earthquakes, those areas facing to the Pacific Ocean over the entire Tohoku area and also a northern part of Kanto areas were hit by unpredictably huge Tsunami waves of up to 40 m height. While travelling up 10 km inland, these waves caused thousands of deaths and severe damage of private and public infrastructure.

Project focuses on a wireless body area network (WBAN) as a core of ideal ubiquitous healthcare infrastructure, which can provide us new paradigm to create innovations for future healthcare in academia and industry by employing advanced wireless technologies which Finland and Japan have been leading in a world. WBAN is a crucial wearable and implant network sensing various vital data for diagnosis and controlling actuators for health treatment around a body, and constructs a ubiquitous healthcare network combining with existing radio, and optical, networks such as a mobile cellular network and Internet. The research is divided into three paradigms: Dependable wireless communication in healthcare applications, developing the IEEE802.15.6-2012 standard, and improving the efficiency of clinical approval for compliance for novel WBAN devices.
