Enhanced Motor Imagery-Based Eeg Classification Using A Discriminative Graph Fourier Subspace

Dealing with irregular domains, graph signal processing (GSP) has attracted much attention especially in brain imaging analysis. Motor imagery tasks are extensively utilized in brain-computer interface (BCI) systems that perform classification using features extracted from Electroencephalogram signals. In this paper, a GSP-based approach is presented for two-class motor imagery tasks classificatio

Bjarne K. H. Semb : The contriver of the first implantation of a total artificial heart in Europe

In 1985, the surgical team led by Bjarne Semb implanted the first total artificial heart (TAH) in Europe, and the following year the first successful bridge to transplant in Europe using the Symbion J-7/100 TAH. Together with the clinical experiences of colleagues in the United States, these early cases preceded the subsequent development of scores of mechanical assist devices to treat advanced he

EEG monitoring after cardiac arrest

Hypoxic–ischaemic brain injury (HIBI) is the main causeof death and disability in patients who are comatose afterreturn of spontaneous circulation (ROSC) from cardiacarrest [1]. Te electroencephalogram (EEG) is a usefultool to assess the severity of HIBI and provide prognostic information. In addition, EEG can be used to diagnoseepileptiform activity in patients with suspected seizuresand monitor

Deprescribing in Palliative Cancer Care

The aim of palliative care is to maintain as high a quality of life (QoL) as possible despite a life-threatening illness. Thus, the prescribed medications need to be evaluated and the benefit of each treatment must be weighed against potential side effects. Medications that contribute to symptom relief and maintained QoL should be prioritized. However, studies have shown that treatment with preven

The Importance of Individual Actor Characteristics and Contextual Aspects for Promoting Industrial Symbiosis Networks

Factors that affect and influence industrial symbiosis (IS) collaborations have been re-searched extensively in the literature, where they are mostly reported at a network level or for IS in general, and lack the individual actor’s perspective. This review article contributes to and expands knowledge of influencing factors and their effect on the individual actor. In a systematic review, guided by

Acoustical Treatments on Ventilation Ducts through Walls : Experimental Results and Novel Models

Sound reduction is complex to estimate for acoustical treatments on ventilation ducts through walls. Various acoustical treatments are available for ventilation ducts, including internal lining (absorption along the inner perimeter), external lagging (external sound insulation), silencer, and suspended ceilings. Previous studies have examined how silencers and the internal lining affect the sound

Robust topological superconductivity in weakly coupled nanowire-superconductor hybrid structures

We investigate the role of the coupling between a spin-orbit coupled semiconductor nanowire and a conventional s-wave superconductor on the emergence of the topological superconducting phase with Majorana bound states in an applied magnetic field. We show that when the coupling is strong, the topological phase transition point is very sensitive to the size of the superconductor and in order to rea

Active generative cooling based on supercritical hydrocarbon fuel is regarded as one of the most promising methods for scramjet thermal management. A large eddy simulation method is used to explore the transient change law of the initial flow, and heat transfer behaviors of supercritical hydrocarbon fuel is in rectangular channels. An oscillation effect can be proved in the convective heat transfe

Interplay of Water-Energy Security and Food Consumption Patterns towards Achieving Nutrition Security in Katsina State, North-Western Nigeria

Everyone has the right to secure water, energy, and food supplies. These essential resources are stressed in many countries. With the current population growth rate and urbanisation, especially in sub-Saharan Africa, there is a need for more food, water, and energy to sustain the increasing population. The aim of this study was to assess the inter-relationship among water and energy in various urb

Assessment of medication discrepancies with point prevalence measurement : how accurate are the medication lists for Swedish patients?

Background: Medication discrepancies are common, potentially harmful and may result from poor medication information across medical records. Our aim was to describe current medication discrepancy rates, types and severity in hospital, primary and specialized outpatient care in Sweden, as well as comparing these with previous measurements. Methods: Participants visiting health care in Skåne in Nove

Quadrupole stability in nonuniform fill patterns

In previous publications, the effect of inhomogeneous beam loading of Landau cavities due to a nonuniform fill pattern in a storage ring has been studied with the aim of predicting the resulting longitudinal profiles of the bunches and their time offsets relative to the main rf [T. Olsson et al., Phys. Rev. Accel. Beams 21, 120701 (2018)PRABCJ2469-988810.1103/PhysRevAccelBeams.21.120701]. This wor

Multi-actor business models in the manufacturing industry. Exploring how first-tier suppliers transition towards circularity.

Adopting circular business models (CBM) represents a key lever for industry to address urgent global challenges. Prior research recognizes the need for systems thinking and collaboration, but existing CBM tools and methods often implicitly assume that the focal firm has direct access to end customers, usage data and end-of-life phases. However, upstream suppliers who lack this access often produce

Adopting business models for sustainability and digitalization. A process study of microlevel dynamics in an incumbent firm.

Incumbent firms face growing pressure to transform their business towards sustainability. However, business models for sustainability (BMfS) and circularity are grounded in fundamentally different institutional logic which, for incumbents, creates tensions with existing business models, structures and routines. How organizations manage tensions from conflicting logics is explored comprehensively i

Ecological impact of introduced and native crayfish on freshwater communities : European perspectives

Interest in the culture of freshwater crayfish throughout Europe has increased during the last few decades. However, the effects of both introduced and native crayfish species on the structure and diversity of freshwater communities has received little attention. In this paper, I review the impact of crayfish on macrophytes, algae, invertebrates, amphibians and fish; also I compare the impact of i

Attitudes to personal carbon allowances : Political trust, fairness and ideology

The idea of personal carbon allowances (PCAs) was presented by the UK Environment Secretary, David Miliband, in 2006. Although no nation state is seriously developing proposals for them, they have been discussed within academia, NGOs and policy-making circles. PCAs can be seen as a logical extension of emissions trading schemes, which has so far only applied at the firm level, to individuals. The

Effectiveness of low-cost non-invasive solutions for daylight and electric lighting integration to improve energy efficiency in historical buildings

This article concerns a field study about the use of non-invasive manual lighting and shading control to save energy in listed buildings. The system was chosen to limit cabling and masonry work. The test room consists of an individual office located in a historical building in Southern Italy. The room was retrofitted with two roller shades (semi-transparent and blackout) and six LED-based pendants

Ocean-land interactions and the Arctic carbon cycle

This chapter focuses on the Arctic since ocean-land interactions are more important for the Arctic than the Antarctic carbon cycle. It explores the complexity of connections between the ocean and land of the North Pole region, and possible impacts on greenhouse gas exchange and lateral carbon flows thereof. Ocean-land interactions in the Arctic integrate the terrestrial and marine environments. Th
