The use of vectoring for crosstalk cancellation in the new ITU-T G.fast standard for next generation DSL systems becomes essential for efficient utilization of the extended bandwidth (up to 200 MHz). In VDSL2 (up to 30 MHz), a zero-forcing-based linear precoder is used in downstream which approaches single-line performance. However, at high frequencies, the linear precoder may amplify the signal p

The Environmental Effects Assessment Panel (EEAP) is one of three Panels that regularly informs the Parties (countries) to the Montreal Protocol on the effects of ozone depletion and the consequences of climate change interactions with respect to human health, animals, plants, biogeochemistry, air quality, and materials. The Panels provide a detailed assessment report every four years. The most re

This paper presents a new approach for the evaluation of User Experience (UX) aspects applied to virtual museums (VM) - VMUXE. A wide percentage of projects and applications for VMs are often "born and buried" in digital labs, without having been experimented and monitored with people. These "prototypes" are the result of experts, technicians, curators, combined together to give birth for multidis

The hypothesis has been tested that evolution has resulted in lower thermal emissivity of eggs of birds breeding openly in cold climates than of eggs of birds that nest under protective covering or in warmer climates. Directional thermal emissivity has been estimated from directional–hemispherical reflectance spectra. Due to several methodological difficulties the absolute emissivity is not accura

Background: Despite the compelling scientific evidence on the superiority of stroke unit care, far from all acute stroke patients have access to stroke unit care. In congruence with what has been observed when other new methods are introduced in health care, we hypothesized that there has been an inequality in the buildup phase of stroke units but that the gradients between patient groups have dec

This work presents a methodology for designing online web presentations reusing a large scale, interactive and immersive VR installation by mapping assets as well as interactions to a low capability environment. With the emergence of WebGL plugin-free interactive 3D graphics inside limited information processing environments, e.g. browser technologies, becomes reality. However, macro VR worlds typ

Aims: In the present study, the effects of Cu (2.0 and 8.0 μM) on root growth of Allium cepa var. agrogarum L. were addressed and protein abundance levels were analyzed using the technology of proteomics combined with transcriptomics, in order to go deeper into the understanding of the mechanism of Cu toxicity on plant root systems at the protein level and to provide valuable information for monit

We investigate the occurrence of water vapour signatures in a total of 10 red giants in the solar neighbourhood at mid-infrared wavelengths (12 pm). With the use of high resolution spectra from TEXES and synthesized spectra based on MARCS model atmospheres, we analyse the differences and discuss plausible causes. These include abundance adjustments, the addition of non-photospheric components (MOL

Background and aims: Arbuscular mycorrhizal fungi (AMF) are ubiquitous in wetland habitats, but their diversity and distribution pattern in these habitats is poorly understood. Under varying hydrological conditions, AMF communities in roots of different wetland species may respond differently due to hydrological and to physiological differences among plants. Here we test this hypothesis.Methods: A

The interplay between cardiac sarcoplasmic Ca2+ATPase and phospholamban is a key regulating factor of contraction and relaxation in the cardiac muscle. In heart failure, aberrations in the inhibition of sarcoplasmic Ca2+ATPase by phospholamban are associated with anomalies in cardiac functions. In experimental heart failure models, modulation of the interaction between these two proteins has been

The IEEE P1687 (IJTAG) standard proposal aims at providing a standardized interface between on-chip embedded logic (instruments), such as scan-chains and temperature sensors, and the IEEE 1149.1 standard which provides test data transport and test protocol for board test. A key feature in P1687 is to include Select Instrument Bits (SIBs) in the scan path to allow flexibility in test architecture d

Risk and vulnerability assessments (RVA) are vital components of the work conducted by public agencies at different levels, as part of the processes for governing and managing risks in the society. In Sweden, public agencies at all levels are required by legislation to perform risk and vulnerability assessments within their respective area of responsibility. The present paper presents a study of h

BACKGROUND: The Swedish school-based vaccination programme offers HPV vaccine to girls born ≥1999 in 5-6th grade. In 2012, all counties introduced free-of-charge catch-up vaccination campaigns targeting girls born 1993-1998. Varying vaccine uptake in the catch-up group by December 2012 suggested that some implementation strategies were more successful than others. In order to inform future vaccina

OBJECTIVES: Breast Imaging-Reporting and Data System (BI-RADS) mammographic density categories are associated with considerable interobserver variability. Automated methods of measuring volumetric breast density may reduce variability and be valuable in risk and mammographic screening stratification. Our objective was to assess agreement of mammographic density by a volumetric method with the radi

A review is made of the basic tools used in mathematics to define acalculus for pseudodifferential operators on Riemannian manifolds endowed with aconnection: existence theorem for the function that generalizes the phase; analogueof Taylor’s theorem; torsion and curvature terms in the symbolic calculus; the twokinds of derivative acting on smooth sections of the cotangent bundle of the Riemannianm

Background: An accurate medication list at hospital admission is essential for the evaluation and further treatment of patients. The objective of this study was to describe the frequency, type and predictors of errors in medication history, and to evaluate the extent to which standard care corrects these errors.Methods: A descriptive study was carried out in two medical wards in a Swedish hospital
