A flexible and reconfigurable 5G networking architecture based on context and content information

2017

The need for massive content delivery is a consolidated trend in mobile communications, and will even increase for next years. Moreover, while 4G maturity and evolution is driven by video contents, next generation (5G) networks will be dominated by heterogeneous data and additional massive diffusion of Internet of Things (IoT). The current network architecture is not sufficient to cope with such traffic, which is heterogeneous in terms of latency and QoS requirements, and variable in space and time. This paper proposes architectural advances to endow the network with the necessary flexibility helping to adapt to these varying traffic needs by providing content and communication services whe…

Designing the 5G network infrastructure: a flexible and reconfigurable architecture based on context and content information

2018

5G networks will have to offer extremely high volumes of content, compared to those of today’s. Moreover, they will have to support heterogeneous traffics, including machine-to-machine, generated by a massive volume of Internet-of-Things devices. Traffic demands will be variable in time and space. In this work, we argue that all this can be achieved in a cost-effective way if the network is flexible and reconfigurable. We present the Flex5Gware network architecture, designed to meet the above requirements. Moreover, we discuss the links between flexibility and reconfigurability, on the one side, and context awareness and content awareness, on the other; we show how two of the building…

Tactics of invisibility : How people in vulnerable positions make datafied everyday life livable

2022

Various data platforms force the individual into constant presence and visibility. However, the ways in which datafied environments relate to experienced vulnerabilities in our everyday lives remain unclear. Through diaries produced by and interviews with participants from three groups who occupy presumably vulnerable positions and who currently live in Finland, we explore the ways in which people challenge expectations and prior assumptions related to forced visibility. Using the concept of tactics developed by de Certeau, we aim to understand how individuals make everyday surveillance culture livable through what we call tactics of invisibility. Based on our analysis, we identify three k…

Distinct immune evasion in APOBEC-enriched, HPV-negative HNSCC

2019

Immune checkpoint inhibition leads to response in some patients with head and neck squamous cell carcinoma (HNSCC). Robust biomarkers are lacking to date. We analyzed viral status, gene expression signatures, mutational load and mutational signatures in whole exome and RNA-sequencing data of the HNSCC TCGA dataset (N = 496) and a validation set (DKTK MASTER cohort, N = 10). Public single-cell gene expression data from 17 HPV-negative HNSCC were separately re-analyzed. APOBEC3-associated TCW motif mutations but not total single nucleotide variant burden were significantly associated with inflammation. This association was restricted to HPV-negative HNSCC samples. An APOBEC-enriched, HPV-nega…

Evaluating actual evapotranspiration by means of multi-platform remote sensing data: A case study in Sicily

2007

During the last two decades, the scientific community developed detailed mathematical models for simulating land surface energy fluxes and crop evapotranspiration rates by means of an energy balance approach. These models can be applied in large areas and with a spatial distributed approach using surface brightness temperature and some ancillary data retrieved from satellite/airborne remote sensed imagery. In this paper a district scale application, in combination with multispectral satellite and airborne data has been carried out to test the potential of two different energy balance models to estimate evapotranspiration fluxes from a set of typical Mediterranean crops (wine, olive, citrus)…

Postural Balance in a Random Sample of 7,979 Subjects Aged 30 Years and Over

2005

<i>Background:</i> Reliable normative data for force platform measurements of postural balance have not been available. <i>Methods:</i> Data on postural balance were collected from a representative nationwide sample of a Finnish population aged ≧30 years (n = 7,979). As part of a comprehensive health survey <i>(Health 2000)</i>, postural balance was measured with the help of a force platform system in four test conditions: normal standing with eyes open and closed (both for 30 s), semi-tandem (20 s) and tandem stand with eyes open (20 s). In addition, balance abilities were also evaluated by a non-instrumented field test. <i>Results:</i> The m…

Influence of the distance in a roundhouse kick's execution time and impact force in Taekwondo.

2009

Taekwondo, originally a Korean martial art, is well known for its kicks. One of the most frequently used kicks in competition is Bandal Chagui or roundhouse kick. Excellence in Taekwondo relies on the ability to make contact with the opponent's trunk or face with enough force in as little time as possible, while at the same time avoiding being hit. Thus, the distance between contestants is an important variable to be taken into consideration. Thirty-one Taekwondo athletes in two different groups (expert and novice, according to experience in competition) took part in this study. The purpose of this study was to examine both impact force and execution time in a Bandal Chagui or roundhouse ki…

An experimental controlled study on postural sway and therapeutic exercise in subjects with low back pain.

2000

Objectives: To describe postural sway and its associations to background factors, low back pain and functional capacity. To evaluate the changes in postural sway after three months of therapeutic exercise in the gym or at home. Design: A one-year randomized experimental trial evaluated postural sway in three study groups: intensive training, home exercise and control group. Setting: Subjects were recruited from seven local occupational health care centres in Central Finland and were examined at Central Finland Hospital by medical doctors. Measurements and therapeutic exercise programmes were carried out in the Research Laboratory of Sport and Health Sciences at Jyväskylä University. Subjec…
