Cell degradation detection based on an inter-cell approach

2017

Fault management is a crucial part of cellular network management systems. The status of the base stations is usually monitored by well-defined key performance indicators (KPIs). The approaches for cell degradation detection are based on either intra-cell or inter-cell analysis of the KPIs. In intra-cell analysis, KPI profiles are built based on their local history data whereas in inter-cell analysis, KPIs of one cell are compared with the corresponding KPIs of the other cells. In this work, we argue in favor of the inter-cell approach and apply a degradation detection method that is able to detect a sleeping cell that could be difficult to observe using traditional intra-cell methods. We d…

The quality of wintering habitats, such as depth of snow cover, plays a key role in sustaining population dynamics of Arctic lemmings. However, few studies so far investigated habitat use during the Arctic winter. Here, we used a unique long-term time series to test whether lemmings are associated with topographical and vegetational habitat features for their wintering sites. We examined yearly numbers and distribution of 22 769 winter nests of the collared lemming Dicrostonyx groenlandicus (Traill, 1823) from an ongoing long-term research on Traill Island, Northeast Greenland, collected between 1989 and 2019, and correlated this information with data on dominant vegetation types, elevatio…

Interannual variation in littoral benthic macroinvertebrate communities under contrasting crayfish predation in a large boreal lake

2014

Long term studies are widely used nowadays in many fields of ecology. For instance, records over years represent a valuable tool to monitor and comprehend environmental changes. In freshwater ecology, long term studies are often applied in restoration effect assessments using a before-after-control-impact design. Little is known about the long term effects of freshwater predators on their prey, for example of how crayfish as omnivorous predators affect macroinvertebrate prey communities. Bottom substrate of stony littoral shores in three sites of Lake Päijänne, in Central Finland, were sampled for macroinvertebrates (MI) during five consecutive years and identified mainly to species. Of the…

AMPA Receptor Auxiliary Proteins of the CKAMP Family

2019

α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are assembled of four core subunits and several additional interacting proteins. Cystine-knot AMPA receptor-modulating proteins (CKAMPs) constitute a family of four proteins that influence the trafficking, subcellular localization and function of AMPA receptors. The four CKAMP family members CKAMP39/shisa8, CKAMP44/shisa9, CKAMP52/shisa6 and CKAMP59/shisa7 differ in their expression profile and their modulatory influence on AMPA receptor function. In this review, I report about recent findings on the differential roles of CKAMP family members.

Optimizing artificial neural networks for the evaluation of asphalt pavement structural performance

2019

Artificial Neural Networks represent useful tools for several engineering issues. Although they were adopted in several pavement-engineering problems for performance evaluation, their application on pavement structural performance evaluation appears to be remarkable. It is conceivable that defining a proper Artificial Neural Network for estimating structural performance in asphalt pavements from measurements performed through quick and economic surveys produces significant savings for road agencies and improves maintenance planning. However, the architecture of such an Artificial Neural Network must be optimised, to improve the final accuracy and provide a reliable technique for enriching d…

Eurobarometer 51.0: The Elderly and Domestic Violence, March-May 1999

2000

This round of Eurobarometer surveys queried respondents on standard Eurobarometer measures, such as whether they attempted to persuade others close to them to share their views on subjects they held strong opinions about, whether they discussed political matters, and what the goals of the European Union (EU) should be. Additional questions focused on the respondents' knowledge of and opinions on the EU, including how well-informed they felt about the EU, what sources of information about the EU they used, and whether their country had benefited from being an EU member. Another major focus of the surveys was elderly people and domestic violence. Respondents were asked whether retired people …

Polycystic ovary syndrome: metabolic consequences and long-term management.

2014

Young women with polycystic ovary syndrome (PCOS) present an increased risk for type II diabetes and cardiovascular diseases. The prevalence of altered glucose tolerance ranges between 20 and 35 % in patients while the prevalence of type II diabetes ranges between 2 and 8 % and seems related to body weight and ethnic group. Moving from the young fertile age to the 40s and the menopause the prevalence of type II diabetes continues to increase compared to the general female population and may reach 10-16 % of PCOS women. However, prevalence of altered glucose tolerance does not increase. Also cardiovascular risk is increased in a large part of young PCOS women but this risk tends to be normal…

Infliximab in severe ulcerative colitis: short-term results of different infusion regimens and long-term follow-up

2007

Background Severe ulcerative colitis is a life-threatening disorder, despite i.v. glucocorticoids treatment. Infliximab has been proposed as a safe rescue therapy. Aim To evaluate short- and long-term effectiveness and safety of infliximab in severe refractory ulcerative colitis. Methods Eighty-three patients with severe ulcerative colitis (i.v. glucocorticoids treatment-refractory) were treated with infliximab in 10 Italian Gastroenterology Units. Patients underwent one or more infusions according to the choice of treating physicians. Short-term outcome was colectomy/death 2 months after the first infusion. Long-term outcome was survival free from colectomy. Safety data were recorded. Resu…
