A formalism was recently introduced to instrument, monitor and control computer applications based on the rate of heartbeats they emit, thereby quantitatively signaling their progress toward goals. To date, the idea was however used essentially in an heuristic manner. This work first shows that a very simple dynamic heartbeat rate model can be devised, an that said model allows to address the corr
Promoting repair of electronics is an important strategy to slow material loops, particularly of critical raw materials, as part of a transition to a circular economy. This contribution accounts for a case study of southern Sweden conducted in order to examine drivers and barriers for repairing electronics, as well as better understand the roles of different stakeholders. Repair activities in the
We investigate the hypothesis that ingestion of a terrestrial or super-Earth planet could cause the anomalously high metal abundances seen in a turn-off star in the open cluster M67, when compared to other turn-off stars in the same cluster. We show that the mass of the convective envelope of the star is likely only 3.45 × 10-3 M⊙, and hence 5.2 M⊙ of rock is required to obtain the observed 0.128
Purpose of Review: Many aspects of reproduction have been associated with increased blood pressure and impaired glucose metabolism that reveals a subsequent increased risk of cardiovascular disease. The aim of this review is to assess reproductive life factors associated with an increased risk of hypertension and cardiovascular disease, e.g., early life programming, sexual, and reproductive health
A fuel mass estimation method for short pilot diesel injections is proposed and analyzed in this article. Previous studies showed that the pilot misfire ratio was more strongly correlated with the fuel mass than the on-time. This characteristic is exploited for the fuel mass estimation in a region where it is otherwise challenging to get good estimation accuracy due to the low signal-to-noise rati
Aging is associated with complex biological changes that can be accelerated, slowed, or even temporarily reversed by biological and non-biological factors. This article focuses on the link between biological aging, psychological stressors, and mental illness. Rather than comprehensively reviewing this rapidly expanding field, we highlight challenges in this area of research and propose potential s
Först halvledarteknik, sedan nanoteknik. Tillsammans utgör de huvuddelen av det vi definierar som modern teknik. Användandet av halvledare revolutionerade teknologin under mitten av 1900-talet genom möjligheten att kunna kontrollera halvledarmaterial till att vara antingen elektriskt isolerande eller ledande. Inom elektroniken utgör halvledarna den viktigaste beståndsdelen i till exempel datorer, The topic of III-V nanowires is still, after more than two decades, a growing and lively research area. The areas of application are wide and contain such important topics as energy harvesting, cheap and efficient lighting, high efficiency detectors and new types of electronics. III-V materials offer properties superior to the widely used Si. They can have considerably higher carrier mobility whic
De moderna kvinnorna med korta kjolar och ännu kortare hår som jazzade sig igenom 1920-talets nöjesliv är en bild som reproduceras i populärkulturen än idag. Men de moderna kvinnorna sågs i sin samtid inte endast som nöjeslystna kommersiella produkter, utan användes som en arena för att diskutera frågor om nationalitet, rasbiologi, genus, kropp och det moderna samhällets utmaningar. De moderna kvi
Two basic routes for planetesimal formation have been proposed over the last decades. One is a classical 'slow-growth' scenario. Another one is particle concentration models, in which small pebbles are concentrated locally and then collapse gravitationally to form planetesimals. Both types of models make certain predictions for the size spectrum and internal structure of newly born planetesimals.
This paper studies the importance of the interdependences within platform-based markets. Specifically, the work examines the influence of complementary product portfolios on the adoption of platforms by individuals. The study analyzes data from a panel of 17 video game platforms in three regions (the US, Japan and Europe) for the period between 1989 and 2011. The results suggest that platform adop
Oath-taking during Roman Antiquity constitutes a telling example of how words and matter interplay and relate to one another. Ancient Latin literature provides a myriad of representations of oaths sworn, both fictive and supposedly historical, where matter somehow figure in the procedure. In this study, a selection of personal oaths from Roman literature are explored in terms of materiality and ag
The present study collected a wide range of experimental data samples, including 855 records from various types of cylindrical weirs under diverse hydraulic conditions, setting the stage for an in-depth analysis for modeling of discharge coefficient. For this purpose, the prediction capability of four kernel-based methods (SVM, GPR, KELM, and KRR) and four neural network-based methods (FFBP, CFBP,
Remembering Classical Scandinavia in Britain, 1760–1830 explores the use of Scandinavian themes in British culture in the decades around 1800. It offers new paradigms for how cultural texts engage with the classical Scandinavian past, historiographically and thematically. The classical Scandinavian past was the subject of intense interest during the period but often also coupled with a sense that
Background: Light microscopy and rapid diagnostic tests (RDT) have long been the recommended diagnostic methods for malaria. However, in recent years, loop-mediated isothermal amplification (LAMP) techniques have been shown to offer superior performance, in particular concerning low-grade parasitaemia, by delivering higher sensitivity and specificity with low laboratory capacity requirements in li
The specific angular momenta (j J/M) of stars (j∗), gas (jgas), baryons as a whole (jb) and dark matter haloes (jh) contain clues of vital importance about how galaxies form and evolve. Using one of the largest samples of disc galaxies (S0-BCD) with high-quality rotation curves and near-infrared surface photometry, we perform a detailed comparative analysis of j that stretches across a variety of
Material interfaces occur at various length scales and may exhibit significantly different properties than the surrounding bulk. Motivated by their importance for electrical engineering applications such as wire bonds and electrically conductive adhesives, the focus of the present work is on material interfaces in electrical conductors. In order to approximate the physical interphase (of finite th
