All ten LIGO/Virgo binary black hole (BH-BH) coalescences reported following the O1/O2 runs have near-zero effective spins. There are only three potential explanations for this. If the BH spin magnitudes are large, then: (i) either both BH spin vectors must be nearly in the orbital plane or (ii) the spin angular momenta of the BHs must be oppositely directed and similar in magnitude. Then there is

We present a software package, Modes, offering h-adaptive and p-adaptive linear multistep methods for first order initial value problems in ordinary differential equations. The implementation is based on a new parametric, grid-independent representation of multistep methods [Arévalo and Söderlind 2017]. Parameters are supplied for over 60 methods. For nonstiff problems, all maximal order methods (

In 2011, a monument commemorating a group of Polish academics killed during the Nazi occupation was unveiled at the site of their death in Lviv, presently a Ukrainian city. This event became the pinnacle of a commemoration that had developed quite autonomously on both sides of the redrawn Polish-(Soviet)Ukrainian border. The commemorative project and memory event underpinning it are especially int

Popular Abstract in Swedish Avsaltning av havsvatten utgör en viktig källa för vattenförsörjning till befolkningen som bor vid Persiska viken, Medelhavet och Röda havet. De tre regionerna utgör ca 11,8 % av världens landyta och hade omkring 9 % av världens befolkning under 1950 och 2008, samt lika mycket enligt prognos för år 2050. Dessa områden är hemvist för 62 %, 58% och 60% av världens avsaltnIn this M.Sc. Thesis of a comparison for sewerage system of the three main municipalities of Turkish Republic of Northern Cyprus (T R N C) has been studied and discussed. The study covers the future population calculations for three municipalities, Nicosia, Famagusta and Kyrenia, by means of Turkish and European standards. The comparisons for sewerage system of the three municipalities are compare

Groundwater resources have come under increasing pressure from overuse and pollution leading to declines in both quantity and quality. As a renewable resource, the continued availability of sufficient and clean groundwater depends on its sustainable use. However, groundwater use has often been unsustainable, and in many countries-both developing and developed-legal and policy frameworks for its su

The interaction of extreme ultraviolet light with matter can lead to the emission of an electron in a process known as photoionization. The electron wavepacket (EWP) created in the continuum propagates on the ionic potential, resulting in a delay compared to an EWP propagating freely. The development of extreme ultraviolet attosecond light sources in recent years has opened the possibility to prob

Introduction: Occupational health and safety management systems are widely used as a systematic approach to managing occupational health and safety. However, sometimes they are restrictive and underspecified to deal with dynamic workplace demands. Rasmussen used a model of boundaries to conceptualize this dynamic model of safety, where the space of possibilities lay within 3 boundaries and workers

Aims/Objective: The development of type 2 diabetes is a result of insulin resistance in various tissues, including skeletal muscle and liver. Apolipoprotein M (ApoM) plays an important role in the function of high-density lipoprotein, and also affects hepatic lipid and glucose metabolism. In this study, we aimed to investigate whether ApoM overexpression modulates glucose metabolism and improves i

Over the course of the past decade, the political economy of global ocean space has entered into a process of significant transformation. In this context, multilateral, corporate and financial attention dedicated to so-called ‘blue growth’ and ‘blue economy’ schemes has been extraordinary; consequentially spawning critical inquiries into the origins and motives behind these initiatives. Offering d

Assessment of tumor-infiltrating lymphocytes (TILs) is increasingly recognized as an integral part of the prognostic workflow in triple-negative (TNBC) and HER2-positive breast cancer, as well as many other solid tumors. This recognition has come about thanks to standardized visual reporting guidelines, which helped to reduce inter-reader variability. Now, there are ripe opportunities to employ co

This dissertation aims to increase the knowledge about how societal contexts shape the social construction of crises in Chinese social media. It consists of four articles to advance current crisis communication research theoretically and empirically. Drawing on the social constructionist approach, Article 1 proposes a theoretical framework for investigating how societal contexts are embedded in cr

In this article, we re‐visit a recent idea of Phillips and Lee (2015. Econometric Reviews 34: 1035 ‐ 1056). They examine an empirically relevant situation when two time series exhibit different degrees of non‐stationarity and one need to learn whether their persistence properties are the same. By bridging the asymptotic theory of local to unity and mildly explosive processes, they construct a Wald

Coronapandemin har inneburit ett hårt slag för café- och restaurangbranschen då kunderna i stor utsträckning uteblir, dels på grund av rädsla för smitta, dels på grund av uppmaningar från myndigheterna om social distansering. I branschen ärmånga småföretagare utan större ekonomisk buffert. Innan krisen är över kommer sannolikt många företag att ha tvingats lägga ned verksamheter (DN, 2020). Vi för
