Habitat Complexity in Aquatic Microcosms Affects Processes Driven by Detritivores
(Public Library Science, 2016-11-01)
Habitat complexity can influence predation rates (e.g. by providing refuge) but other ecosystem processes and species interactions might also be modulated by the properties of habitat structure. Here, we focussed on how ...
Health services research in patients with breast cancer (CAMISS-prospective): study protocol for an observational prospective study
(Biomed Central, 2019-01-08)
Background: Though breast cancer remains a major health problem, there is a lack of information on health care provided to patients with this disease and associated costs. In addition, there is a need to update and validate ...
Improving Content Delivery Efficiency through Multi-Layer Mobile Edge Adaptation
(IEEE, 2015-11)
This paper presents a novel architecture for optimizing the HTTP-based multimedia delivery in multi-user mobile networks. This proposal combines the usual client-driven dynamic adaptation scheme DASH-3GPP with network-assisted ...
Dealing with Energy-QoE Trade-Offs in Mobile Video
(Hindawi Publishing Corporation, 2013)
Scalable video coding allows an efficient provision of video services at different quality levels with different energy demands. According to the specific type of service and network scenario, end users and/or operators ...
Forecast And Analysis Of The Cosmological Redshift Drift
(Springer, 2018-01-08)
The cosmological redshift drift could lead to the next step in high-precision cosmic geometric observations, becoming a direct and irrefutable test for cosmic acceleration. In order to test the viability and possible ...
Obesity Parameters, Physical Activity, And Physical Fitness are Correlated With Serum Dipeptidyl Peptidase IV Activity In A Healthy Population
(Elsevier, 2018-05)
Objective: To determine whether obesity, physical fitness, and physical activity parameters are associated with the enzymatic activity of serum dipeptidyl peptidase IV (sDPPIV) in a sample of healthy women and men.
Design ...
Sex differences in the aging pattern of renin–angiotensin system serum peptidases
(Biomed Central, 2017-02-03)
Background: Serum peptidases, such as angiotensin-converting enzyme (ACE), angiotensin-converting enzyme-2 (ACE2), neutral endopeptidase (NEP), aminopeptidase N (APN), and aminopeptidase A (APA), are important elements of ...
Ultra Light Axionic Dark Matter: Galactic Halos and Implications for Observations with Pulsar Timing Arrays
(MDPI, 2018-01-16)
The cold dark matter (CDM) paradigm successfully explains the cosmic structure over an enormous span of redshifts. However, it fails when probing the innermost regions of dark matter halos and the properties of the Milky ...
Size Dependence of the Magnetoelastic Properties of Metallic Glasses for Actuation Applications
(MDPI, 2019-10-04)
We present an exhaustive study of the magnetoelastic properties of 24 strips with different rectangular dimensions, cut from a long ribbon of Metglas((R)) 2826MB3. The strips have a length-to-width ratio R = L/w ranging ...
Video Quality Prediction Models Based on Video Content Dynamics for H.264 Video over UMTS Networks
(Hindawi Publishing Corporation, 2010)
The aim of this paper is to present video quality prediction models for objective non-intrusive, prediction of H.264 encoded video for all content types combining parameters both in the physical and application layer over ...
