Frequency-selective wallpaper for indoor interference reduction and MIMO capacity improvement
This paper presents the design and features of frequency-selective wallpaper-based on periodic and symmetric metallic hexagons-intended to be attached to standard walls for filtering out 5GHz signals (e.g., IEEE 802.11a systems)without blocking other selected radio communication services (e.g., cellular mobile communication signals). It analyzes the characteristics of the radio channel-as found wi

Dual-precision fixed-point arithmetic for low-power ray-triangle intersections
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
Closely related dinoflagellate species in vastly different habitats–an example of a marine–freshwater transition
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
Pre-treatment allostatic load and metabolic dysregulation predict SSRI response in major depressive disorder : A preliminary report
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 changes in ENSO-induced tropical Pacific precipitation variability in the past warm and cold climates from the EC-Earth simulations
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
Conceptual Design of a Kraft Lignin Biorefinery for the Production of Valuable Chemicals via Oxidative Depolymerization
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
The prevalence of HPA-1a alloimmunization and the potential risk of FNAIT depend on both the DRB3*01:01 allele and associated DR-DQ haplotypes
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
The Upright Tiara of the Persian King
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 theright to wear the headgear in an upright position, usually referred to as tiara orthé.The cap was part of the so-called Median riding dress, and was This paper examines a piece ofheadgear, usually referred to in modern literature as a Phrygian or Persian cap, but variously described astiara, kurbasiaor kidaris/kitarisin the ancient sources.

Vancouver Declaration II on Global Headache Patient Advocacy 2019
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
Impact of α-synuclein pathology on transplanted hESC-derived dopaminergic neurons in a humanized α-synuclein rat model of PD
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
Early and sustained symptom improvement with umeclidinium/vilanterol versus monotherapy in COPD : a post hoc analysis of the EMAX randomised controlled trial
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

Utvecklingen av generiska pronomen i svenskans historia – tre exempel på grammatikalisering?
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
Gendering foreign policy : A comparative framework for analysis
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
Iron Deficiency in Left Ventricular Assist Device Recipients
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
Fatigue One to Five Years after Lung Transplantation
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
Sub-Kelvin hysteresis of the dilanthanide single-molecule magnet Tb2ScN@ C80
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
