This 1 sonata uses simple generative principles, to develop networks of relatively high complexity in which intuition actively participates to produce an output with a certain degree of activity and acoustic nonlinearity.Albert-László Barabási, from the introduction to his book titled Linked: the new science of networks, “Just as diverse humans share skeletons that are almost indistinguishable,
Research Question/Issue: This paper examines the impact of changes in board independence on the market valuation of Swedish firms. I exploit an exogenous change to the rules of corporate governance in 2005, which requires large firms to have majority independent boards, as a quasi‐experimental setting.Research Findings/Insights: I use a regression discontinuity design and a difference‐in‐differenc
Shrunken pore syndrome (SPS) is a condition in which estimated glomerular filtration rate (eGFR) based upon cystatin C is lower than eGFR based upon creatinine. It has been associated with increased mortality even in the presence of normal GFR in both a cardiac surgical population and a general population. No systematic studies of the varia
Background: Twenty percent of the patients with AAA have an aneurysm involving the common iliac arteries. Large common iliac diameter can be treated with an iliac branched device or extension of the stent graft to the external iliac artery with occlusion of the ipsilateral internal iliac artery (IIA) to prevent type 2 endoleaks. This study describes and evaluates a embolization technique using Ony
We propose drl-RPN, a deep reinforcement learning-based visual recognition model consisting of a sequential region proposal network (RPN) and an object detector. In contrast to typical RPNs, where candidate object regions (RoIs) are selected greedily via class-agnostic NMS, drl-RPN optimizes an objective closer to the final detection task. This is achieved by replacing the greedy RoI selection pro
Discontinuous Galerkin (DG) methods offer a great potential for simulations of turbulent and wall bounded flows with complex geometries since these high-order schemes offer a great potential in handling eddies. Recently, space-time DG methods have become more popular. These discretizations result in implicit schemes of high order in both spatial and temporal directions. In particular, we consider
Summary: In elderly men included in MrOS-Sweden, subclinical hyperthyroidism (SHyper) was markedly associated with increased risk of vertebral fractures. Introduction: Overt hyperthyroidism is associated with increased risk of fractures. However, only a few studies have investigated whether SHyper is associated with fracture risk in elderly men. We therefore investigated if SHyper was a risk facto
This paper discusses methods to test the performance of the adaptation layer in a self-adaptive system. The problem is notoriously hard, due to the high degree of uncertainty and variability inherent in an adaptive software application. In particular, providing any type of formal guarantee for this problem is extremely difficult. In this paper we propose the use of a rigorous probabilistic approac
Purpose: The research community has focused on defining reliable biomarkers for the early detection of the pathological hallmarks of Alzheimer’s disease (AD). In 2017, the Geneva AD Biomarker Roadmap initiative adapted the framework for the systematic validation of oncological biomarkers to AD, with the aim to accelerate their development and implementation in clinical practice. The aim of this wo
Sedan antiken har humanismen försökt definiera den mänskliga naturens väsen samtidigt som den placerar människan i universums centrum som ”alla tings mått”. I ett försök att omvärdera människans betydelse har det talats om ett slags transhumanistisk intersubjektivitet. Jag utgår från fysikern och feministen Karen Barads begrepp intraaktion (samspel mellan integrerade delar). Barad myntar begreppet
Automated soil moisture systems are commonly used in precision agriculture. Using low-cost sensors, the spatial extension can be maximized, but the accuracy might be reduced. In this paper, we address the trade-off between cost and accuracy comparing low-cost and commercial soil moisture sensors. The analysis is based on the capacitive sensor SKU:SEN0193 tested under lab and field conditions. In a

We report on the detection of a remarkable new fast high-energy transient found in the Chandra Deep Field-South, robustly associated with a faint (mR = 27.5mag, zph ~2.2) host in the CANDELS survey. The X-ray event is comprised of 115+12 -11 net 0.3-7.0 keV counts, with a light curve characterized by an ~100 s rise time, a peak 0.3-10 keV flux of ~5 × 10-12 erg s-1 cm-2 and a power-law decay time
We investigate here populations of cataclysmic variables (CVs) in a set of 288 globular cluster (GC) models evolved with the MOCCA code. This is by far the largest sample of GC models ever analysed with respect to CVs. Contrary to what has been argued for a long time, we found that dynamical destruction of primordial CV progenitors is much stronger in GCs than dynamical formation of CVs, and that
Background: Proficient Human Papillomavirus (HPV) genotyping services are essential to support HPV and cervical cancer elimination strategies, in particular to support HPV vaccine research. Objectives: To perform a global HPV genotyping proficiency study, with evaluation in relation to previous proficiency studies. Study design: The proficiency panel contained 44 coded samples (40 samples containi
Multi-objective optimization is a crucial matter in computer systems design space exploration because real-world applications often rely on a trade-off between several objectives. Derivatives are usually not available or impractical to compute and the feasibility of an experiment can not always be determined in advance. These problems are particularly difficult when the feasible region is relative
Importance: Women with adverse pregnancy outcomes, such as preterm delivery or preeclampsia, have higher future risks of cardiometabolic disorders; however, little is known about their long-term mortality risks. A better understanding of such risks is needed to facilitate early identification of high-risk women and preventive actions. Objective: To determine long-term mortality risks associated wi
Effects of pilot H2 injection on the thermoacoustic instability of premixed CH4/air flames were experimentally investigated with varied hydrogen injection rates and different injection strategies. The flames were stabilized on a swirl burner with a central pilot-fuel injection tube. The flame structure was captured using high-speed OH* chemiluminescence and OH-PLIF methods, while the CO and NOx em
Around the world today, universities are expected to play a unique role as creators of regional growth and innovation. While there appears to be a consensus that the role of universities has been expanded, critiques show that the contribution of universities to their regions is still not well defined. There have been some developments in the literature on the concept of modern universities such as
