Performance simulation investigation of TINA networks

The paper discusses the performance of TINA (Telecommunications Information Networking Architecture). The TINA architecture allows both multiple service vendors and multiple network providers. It is developed by a consortium which includes network operators and telecommunication and computer equipment suppliers. The foundation of TINA is object orientation and distributed computing. A computationa

Masculinity and Violence in Vietnam 1

In this essay, I draw on fieldwork conducted in Vietnam to reflect on their meaning and implications for understanding continuity and change in patterns of intimate partner violence in Vietnamese society. Current discussions in Vietnam of men’s violence against women elucidate both efforts to deal with a societal problem and manage it in ways, which tend to maintain the gendered asymmetries within

Weak products of complete pick spaces

Let H be the Drury-Arveson or Dirichlet space of the unit ball of Cd. The weak product H ☉ H of H is the collection of all functions h that can be written as h =∑∞n=1 fngn, where ∑∞n=1 ||fn|| ||gn|| < ∞. We show that H ☉ H is contained in the Smirnov class of H; that is, every function in H ☉ H is a quotient of two multipliers of H, where the function in the denominator can be chosen to be cyclic

The mineralosphere—interactive zone of microbial colonization and carbon use in grassland soils

To improve our understanding of early microbial colonization of pristine minerals and their group-specific C utilization, we exposed minerals (illite/goethite/quartz) amended with artificial root exudates (ARE, glucose, and citric acid) in grassland soils for a period of 24 weeks. FTIR spectra indicated that mineral-associated ARE were used within the first 2 weeks of exposure and were replaced by

The validation status of blood biomarkers of amyloid and phospho-tau assessed with the 5-phase development framework for AD biomarkers

Purpose: The development of blood biomarkers that reflect Alzheimer’s disease (AD) pathophysiology (phosphorylated tau and amyloid-β) has offered potential as scalable tests for dementia differential diagnosis and early detection. In 2019, the Geneva AD Biomarker Roadmap Initiative included blood biomarkers in the systematic validation of AD biomarkers. Methods: A panel of experts convened in Nove

Synthesis of Vertically Aligned ZnO Nanorods Using Sol-gel Seeding and Colloidal Lithography Patterning

Different ZnO nanostructures can be grown using low-cost chemical bath deposition. Although this technique is cost-efficient and flexible, the final structures are usually randomly oriented and hardly controllable in terms of homogeneity and surface density. In this work, we use colloidal lithography to pattern (100) silicon substrates to fully control the nanorods' morphology and density. Moreove

Thermal Performance Analysis in a Zigzag Channel Printed Circuit Heat Exchanger under Different Conditions

In this study, the effect of axial heat conduction on thermal performance in a zigzag channel printed circuit heat exchanger (PCHE) with supercritical liquefied natural gas as the working fluid is studied by a numerical method under different conditions. The influence factors include Reynolds number, operating pressure, inlet temperatures of the cold side, and wall thermal conductivity. The result

Performance of Swedish children on a dynamic motor speech assessment

Purpose: This study was designed to evaluate the performance of typically developing Swedish-speaking children on DYMTA (Dynamisk Motorisk Talbedömning), a Swedish dynamic motor speech assessment. Method: Participants were 94 children, 45 boys/49 girls (9/8 multilingual), with typical oral motor, speech, and language skills, between 37 and 106 months divided into five age-groups. They performed tw

A Biomimetic Evolvable Organic Electrochemical Transistor

Biomimicry at the hardware level is expected to overcome at least some of the challenges, including high power consumption, large footprint, two-dimensionality, and limited functionality, which arise as the field of artificial intelligence matures. One of the main attributes that allow biological systems to thrive is the successful interpretation of and response to environmental signals. Taking in

The future is old – Patients with topical ocular hypotensive treatment in the Nordic region between 2008 and 2017 with projections for 2040

Purpose: The primary objective was to evaluate prescribing trends for topical ocular hypotensive treatment in the Nordic region during the last decade and, by population projections, estimate the glaucoma burden in 2040. A secondary objective was to analyse national variations in prescription patterns across the Nordic region. Methods: A retrospective analysis of national pharmacy data between 200

Outcome of PCI with Xience versus other commonly used modern drug eluting stents : A SCAAR report

Objectives: To analyze the clinical outcome of percutaneous coronary intervention (PCI) using the Xience drug eluting stent (DES) versus other modern DES. Methods: This retrospective study based on the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) analyzed the outcome of PCI using Xience versus other commonly used modern DES, 2007 to 2017. The primary outcome measure was a combinat

Effect of nocturnal Temperature-controlled Laminar Airflow on the reduction of severe exacerbations in patients with severe allergic asthma : a meta-analysis

Background: Allergen avoidance is important in allergic asthma management. Nocturnal treatment with Temperature-controlled Laminar Airflow (TLA) has been shown to provide a significant reduction in the exposure to allergens in the breathing zone, leading to a long-term reduction in airway inflammation and improvement in Quality of life (QoL). Allergic asthma patients symptomatic on Global Initiati
