Ray-Triangle intersection is a fundamental computation in most ray tracing algorithms. The prohibitive cost of the ray-triangle test algorithms, however, limits the utilization of these algorithms in settings with low power budgets, such as mobile systems. In this work, we analyze the precision requirements for ray-triangle intersection and observe that for most of the rays a low-precision is suff

Phytoplankton are present in a large variety of aquatic environments, ranging from small freshwater ponds to the oceans. Typically, freshwater and marine species are not closely related, indicating an ancient divergence and that salinity poses a strong dispersal barrier. Here we reveal a common recent origin of two dinoflagellates that are well adapted to different habitats. Gymnodinium baicalense

BackgroundMajor depressive disorder (MDD) is associated with increased allostatic load (AL; a measure of physiological costs of repeated/chronic stress-responding) and metabolic dysregulation (MetD; a measure of metabolic health and precursor to many medical illnesses). Though AL and MetD are associated with poor somatic health outcomes, little is known regarding their relationship with antidepres

The El Niño-Southern Oscillation (ENSO) is one of the most significant climate variability signals. Studying the changes in ENSO-induced precipitation variability (ENSO precipitation) in the past climate offers a possibility to a better understanding of how they may change under future climate conditions. This study uses simulations performed with the European community Earth-System Model (EC-Eart

Lignin is the most abundant aromatic biopolymer on Earth, and its aromatic structure makes it a promising platform for the production of biobased chemicals and other valuable building blocks. The valorization of lignin into chemicals currently presents a challenge, and its facilitation is key in the development of viable lignocellulosic biorefinery processes. This study presents a conceptual desig

Alloimmunization against human platelet antigen (HPA)-1a during pregnancy can cause foetal/neonatal alloimmune thrombocytopenia (FNAIT) and severe bleeding in the foetus or newborn and likely depends on several factors. HPA-1a alloimmunization is associated with DRB3*01:01, which is associated with several DR-DQ haplotypes. However, it is not known to what extent these haplotypes contribute to the

This paper examines a piece of headgear, usually referred to in modern literature asa Phrygian or Persian cap, but variously described as tiara, kurbasia or kidaris/kitaris in the ancient sources.

According to Greek texts only the Persian king had the right to wear the headgearin an upright position, usually referred to as tiara orthé. The cap was part of the so-called Median riding dress, and was wo

In 2017, the International Headache Society convened a Global Patient Advocacy Summit (GPAS-1) to begin a collaborative effort involving patients, patient advocates, patient advocacy organizations, healthcare professionals, scientists, professional pain, neurology, and headache societies, pharmaceutical manufacturers, and regulatory agencies to advance issues of importance to patients affected by

Preclinical assessment of the therapeutic potential of dopamine (DA) neuron replacement in Parkinson's disease (PD) has primarily been performed in the 6-hydroxydopamine toxin model. While this is a good model to assess graft function, it does not reflect the pathological features or progressive nature of the disease. In this study, we establish a humanized transplantation model of PD that better

Background: In chronic obstructive pulmonary disease (COPD), both the time needed for patients to gain symptom improvement with long-acting bronchodilator therapy and whether an early response is predictive of a sustained response is unknown. This study aimed to investigate how quickly meaningful symptom responses are seen in patients with COPD with bronchodilator therapy and whether these respons

I avhandlingen Man, en och du – generiska pronomen i svenskans historia (Skärlund 2017a) kartläggs de förändringar de tre orden man, en och du har genomgått som generiska pronomen i svenska språket från 1200-talet till idag, med utgångspunkt i teorier om grammatikalisering. I den här artikeln samman-fattas några av undersökningens viktigaste resultat och det diskuteras huruvida ordens utveckling b

This article seeks to explain the rise of pro-gender norms and feminist strategies in foreign policy, which are increasingly salient in global politics. How can this trend be theorized? In what ways is this development resisted and contested by other states and international actors? To what extent can we trace continuity and change in regard to gender and foreign policy? To address these major res

PURPOSE: The prevalence of iron deficiency (ID) in Left Ventricular Assist Device (LVADs) recipients is not known nor has the association between ID and peak oxygen uptake (VO2) been reported. The aim of this study was to study to investigate the prevalence of ID in this population and the association between ID and VO2. METHODS: Data was included from LVAD recipients at Rigshospitalet, Denmark (D

PURPOSE: The knowledge is scarce regarding how recovery and well-being after lung transplantation is affected by various symptoms. Thus, little is known about self-management support for these recipients. Since fatigue is a symptom that severely impair well-being, the aim of this study was to explore associations between fatigue and influencing factors as perceived self-efficacy, social and psycho

Magnetic hysteresis is a direct manifestation of nonequilibrium physics that has to be understood if a system is to be used for information storage and processing. The dilanthanide endofullerene Tb2ScN@C80 is shown to be a single-molecule magnet with a remanence time on the order of 100 s at 400 mK. Three different temperature-dependent relaxation barriers are discerned. The lowest 1 K barrier is

Svenska staten äger 46 olika bolag (2020), vars aktiviteter årligen sammanfattas i rapporten Verksamhetsberättelse för företag med statligt ägande, utgiven av regeringen. År 2007 slog regeringen fast att de statliga företagen måste rapportera om sitt hållbarhetsarbete varje år, och 2016 inkluderades också Agenda 2030 och FN:s 17 globala mål för en hållbar utveckling i den statliga ägarpolicyn. Men

Newspapers in Sweden are experiencing reduced revenues due to decreases in advertisement sales and reader subscriptions. Given such circumstances, one way of being more cost-effective is for journalists to recycle pieces of texts already published by others. In this article, I investigate to what extent and how the four biggest newspapers in Sweden do this. Following a close reading of 120 article

PURPOSE: To investigate the survival of heart transplant (HTx) recipients during different time periods in Sweden. We hypothesized that the survival for HTx recipients has improved following advancements in the management of these patients. METHODS: Data was obtained through the database of the organ exchange organization Scandiatransplant. All patients who underwent HTx in Sweden between Jan 1988
