Bridge Networking Research and Internet Standardization: Case Study on Mobile Traffic Offloading and IPv6 Transition Technologies

Abstract. The gap between networking research communities and Internet standardization organizations (SDOs) has been growing over the years, which has drawn attention from both academic and industrial sides due to its detrimental impact. The reason behind this widening gap is complex and typically beyond the mere technology ground. In this position paper we share our perspectives toward this challenge based on our hands-on experience obtained from joint projects with universities and companies. We highlight the lessons learned, covering both successful and under-performed cases, and further suggest viable solutions to bridge the gap between networking research and Internet standardization, aiming to promote and maximize the outcome of such collaborative endeavours.

Acceptability of flavoured pharmaceutically non-active mini-tablets in pet cats tested with a rapid 3-portal acceptance test with and without food

Palatable oral pharmaceuticals are crucial for feline medication. The pharmaceutical industry prefers synthetic flavours over organic ones because of hygiene and regulatory issues. The aim of this study was to find a palatable synthetic flavour for future taste-masking of feline pharmaceuticals. The hypothesis was that synthetic meat aromas and free amino acids would be palatable to cats. The palatability of 18 synthetically flavoured mini-tablets was screened with 10–19 pet cats using a rapid 3-portal acceptance test with and without food. The tested flavours were synthetic amino acids (L-carnitine, l-glutamic acid monosodium salt hydrate, l-leucine, l-methionine, l-phenylalanine, l-proline, and taurine), d-(+)-Maltose monohydrate and thiamine hydrochloride. Furthermore, thiamine hydrochloride was combined with amino acids (l-cysteine, l-leucine, l-methionine and l-proline) and synthetic meat flavours (2-acetylpyridine, 2-acetylthiazole, 2-pentylpyridine and 4-hydroxy-5-methyl-3(2H)-furanone). The negative control was a non-flavoured placebo mini-tablet, while positive controls were an organic yeast-flavoured mini-tablet and a yeast- and fish-based commercial vitamin tablet in mini-tablet form. No significant differences were detected between palatable synthetic flavours and the placebo, nor between the synthetic flavours and the yeast flavour. In general, the mini-tablet seemed to be small enough to be accepted inside a food item. These results differ from the earlier literature about the taste preferences of cats for amino acids, and hence free amino acids should not be considered palatable to cats based purely on previous findings.Peer reviewe

Cost analysis of a randomized stem cell mobilization study in multiple myeloma

Upfront autologous stem cell transplantation (ASCT) is the standard therapy for younger multiple myeloma (MM) patients. MM patients usually undergo stem cell mobilization with cyclophosphamide (CY) followed by granulocyte colony-stimulating factor (G-CSF), or with G-CSF alone. A limited number of randomized studies are available comparing costs of different mobilization strategies. Eighty transplant-eligible patients aged up to 70 years with untreated MM were included in this prospective study. The patients were treated with RVD induction for three 21-day cycles and randomized 1: 1 at inclusion into one of the two mobilization arms CY 2 g/m(2) + G-CSF [arm A] vs. G-CSF alone [arm B]. Plerixafor was given according to a specific algorithm if needed. Sixty-nine patients who received mobilization followed by blood graft collection were included in the cost analysis. The median total costs of the mobilization phase were significantly higher in arm A than in arm B (3855 (sic) vs. 772 (sic), pPeer reviewe

MAGIC polymer gel for dosimetric verification in boron neutron capture therapy

"Radiation-sensitive polymer gels are among the most promising three-dimensional dose verification tools developed to date. We tested the normoxic polymer gel dosimeter known by the acronym MAGIC (methacrylic and ascorbic acid in gelatin initiated by copper) to evaluate its use in boron neutron capture therapy (BNCT) dosimetry. We irradiated a large cylindrical gel phantom (diameter: 10 cm; length: 20 cm) in the epithermal neutron beam of the Finnish BNCT facility at the FiR 1 nuclear reactor. Neutron irradiation was simulated with a Monte Carlo radiation transport code MCNP. To compare dose-response, gel samples from the same production batch were also irradiated with 6 MV photons from a medical linear accelerator. Irradiated gel phantoms then underwent magnetic resonance imaging to determine their R2 relaxation rate maps. The measured and normalized dose distribution in the epithermal neutron beam was compared with the dose distribution calculated by computer simulation. The results support the feasibility of using MAGIC gel in BNCT dosimetry.""Radiation-sensitive polymer gels are among the most promising three-dimensional dose verification tools developed to date.

Executing circular economy strategies in practice in Finland. Results and experiences from Circwaste project

A Europe-wide circular economy policy was launched in 2014 when the European Commission published the first strategic policy programme for circular economy. It was compiled to provide very comprehensive impacts and dimensions of sustainable development: sustainable growth and a climate neutral, resource efficient and competitive economy. The targets of a circular economy are that the value of products, materials and resources is maintained in the economy for as long as possible, economic growth is decoupled from resource use, generation of waste and environmental loads are minimised, and pressure on the Earth’s resources and biodiversity is minimised. The European Union is supporting the sustainability transition with research and development funding. In Finland, Circwaste – Towards Circular Economy is one of the biggest development projects accelerating the transition to a circular economy. During the period 2016–2020, the project has produced monitoring data on the development of circular economy and the sustainability of waste management, highlighted the circular economy concept, promoted stakeholder collaboration, supported strategic national processes, strengthened know-how and mainstreamed and concretised circular economy thinking. This interim report presents all the relevant results so far. It is crucial that data is produced from different angles on implementing the circular economy. More information is needed both to support decision making and on connections between and reflections on different factors. The key figures for Finland show quite clear coupling of the use of natural resources, waste amounts and economic growth. The circular material use rate is ca. 7%, which can be considered quite modest. Quantitative national targets for decreasing the use of natural resources are needed. Instead of country comparisons, the focus should be on trends in order to learn from the past and to identify the policy instruments needed to achieve the level aspired to. One of the key findings is the need for regional indicators and data for decisionmaking. The work done within Circwaste is the first effort towards a systematic monitoring scheme for monitoring circular economy regionally. The study showed that the production of regional waste data is challenging, that the estimated recycling rates have not increased adequately to reach the EU targets and that there could therefore be a need for municipallevel recycling targets. The transition to a circular economy also causes fundamental social changes in society. In the project, new indicators were developed for measuring social impacts: circular economy employment, education and employment for vulnerable groups, publicly shared resources, accessibility of recycling services and sustainable vehicle fuels. The first baseline data show advances towards the circular economy: the accessibility of waste management services has improved, the Finnish educational system has been able to respond quickly to the need for circular economy education, circular economy activities have potential for the employment of vulnerable groups and economic activities related to recycling, repair and reuse have grown. The regions and municipalities emerge as key actors in facilitating a socially just transition towards a circular economy. The study on innovative material processing technologies gathered data on technologies for elemental recycling, especially for plastic waste but also for making new fibres from textiles waste. Financial issues are key to the survival of these technologies and there is a need for governmental financial support. Public procurers can be considered key players in the circular economy, creating demand for more sustainable products and services. Implementing circular economy in municipalities requires commitment, financial planning, interaction with regional actors and inclusion of circular economy in financial rules. The construction sector is a major consumer of natural resources, but the municipalities can make construction more sustainable through public procurements and planning. As buyers, they can require the use of recycled raw materials and soils in construction projects. Obligations for ecological compensation and goals of no net loss of biodiversity would decrease the pressure on natural resources. To support municipalities in their work, a national organisation for providing municipal auditing, development, education and business support services could be established. Employing circular economy experts in each municipality to work as crossadministrative coordinators could enhance the transition. The project has created a lot of political, theoretical and practical content on the concept and field of circular economy. The next steps are to further develop and widen, as well as deepen, the results and to provide national support in searching for answers and solutions for decreasing the use of natural resources, achieving the MSW recycling targets and creating a more sustainable society
