Forage Potential of Cereal–Legume Mixtures as an Adaptive Climate Change Strategy under Low Input Systems

Mixed cropping systems can constitute important agroecological adaptation strategies for enhancing crop growth and productivity in view of climate change, while reducing the need for synthetic fertilizers and providing important ecosystem services. The aim of this study was to investigate growth, competitiveness, and productivity of two forage mixtures combining triticale (X triticosecale Wittmack

Occurrence of comorbidity following osteoarthritis diagnosis : a cohort study in the Netherlands

Objective: To determine the risk of comorbidity following diagnosis of knee or hip osteoarthritis (OA). Design: A cohort study was conducted using the Integrated Primary Care Information database, containing electronic health records of 2.5 million patients from the Netherlands. Adults at risk for OA were included. Diagnosis of knee or hip OA (=exposure) and 58 long-term comorbidities (=outcome) w

Investigating Partially Discordant Results in Phase 3 Studies of Aducanumab

Objectives: Efficacy and safety results from the EMERGE (NCT02484547) and ENGAGE (NCT02477800) phase 3 studies of aducanumab in early Alzheimer’s disease (AD) have been published. In EMERGE, but not in ENGAGE, high-dose aducanumab demonstrated significant treatment effects across primary and secondary endpoints. Low-dose aducanumab results were consistent across studies with non-significant differ

An experimental and theoretical investigation on Ti-5553/WC–Co(6%) chemical interactions during machining and in diffusion couples

Chemical interactions that drive crater wear in turning are often studied using diffusion couples where the tool and workpiece are fixed. In contrast, in actual turning, there is a constant supply of new workpiece material at the tool-chip interface. In this work, diffusion simulations of a WC–Co(6%) and Ti–5Al–5V system were conducted, with constant replenishment of titanium at the interface (ope

A Multi-Stakeholder Perspective on Barriers to a Fossil-Free Urban Freight System

The purpose of this study is to provide a system perspective on the barriers to the development of a fossil-free and thus more sustainable urban freight system and to provide insights regarding these barriers and how they impede progress. The system perspective complements earlier research, where barriers were identified in delimited parts of freight systems. Here, the urban freight system in a Sw

Water quality modeling of a eutrophic drinking water source : Impact of future climate on Cyanobacterial blooms

Cyanobacterial blooms are becoming more frequent in freshwater sources, causing concern throughout the world. Cyanobacterial blooms affect human health and the entire environment. Numerical modeling is an effective tool for investigating aquatic systems. In this study, a 3D hydrodynamic and water quality (ecological) model was used to simulate eutrophication of a drinking water source, Lake Vomb,

Scaling-up the biodiversity–ecosystem functioning relationship : the effect of environmental heterogeneity on transgressive overyielding

Knowledge of how biodiversity sustains ecosystem function comes predominantly from studies focused on small spatial scales. Thus, we know relatively little about the role of biodiversity at larger scales of space and time where habitats become increasingly heterogeneous. Efforts to upscale the relationship between biodiversity and function have yielded inconclusive results. Given that increasing h

An LO phase shifter with frequency tripling and phase detection in 28 nm FD-SOI CMOS for mm-wave 5G transceivers

This paper presents an LO phase shifter with frequency tripling for 28-GHz 5G transceivers. The phase shifting and frequency tripling are achieved using an injection-locked oscillator and injection-locked frequency tripler, respectively. A phase detector based on third harmonic mixing is also implemented and is used to detect the applied phase shift, supporting automatic calibration of the phase s

Epithelioid and Spindle Cell Hemangioma : Clinicopathologic Analysis of 18 Primary Bone and Soft Tissue Tumors Highlighting a Predilection for the Hands and Feet, Frequent Multicentricity, and Benign Behavior

Epithelioid and spindle cell hemangioma was initially described in 1999 in a series of primary bone tumors and was subsequently suggested by some to represent a variant of epithelioid hemangioma. Here, we studied 18 epithelioid and spindle cell hemangiomas. Nine patients (50%) were male. Age at presentation ranged from 12 to 78 years (median: 38.5 y). Nine patients (50%) had tumor(s) limited to bo

Acute and chronic toxicity of imidacloprid in the pollinator fly, Eristalis tenax L., assessed using a novel oral bioassay

Imidacloprid is a neonicotinoid neurotoxin that remains widely used worldwide and persists in the environment, resulting in chronic exposure to non-target insects. To accurately map dose-dependent effects of such exposure across taxa, toxicological assays need to assess relevant modes of exposure across indicator species. However, due to the difficulty of these experiments, contact bioassays are m

Future Swedish 3D City Models : Specifications, Test Data, and Evaluation

Three-dimensional city models are increasingly being used for analyses and simulations. To enable such applications, it is necessary to standardise semantically richer city models and, in some cases, to connect the models with external data sources. In this study, we describe the development of a new Swedish specification for 3D city models, denoted as 3CIM, which is a joint effort between the thr

A multi-scale in silico mouse model for diet-induced insulin resistance

Insulin resistance causes compensatory insulin production, which in humans can eventually progress to β-cell failure and type 2 diabetes (T2D). This disease progression involves multi-scale processes, ranging from intracellular signaling to organ and whole-body level regulations, on timescales from minutes to years. T2D progression is commonly studied using overfed and genetically modified rodents

Predictors of patient-reported fatigue symptom severity in a nationwide multiple sclerosis cohort

Background: Fatigue is a debilitating symptom of multiple sclerosis (MS), but its relation to sociodemographic and disease-related characteristics has not been investigated in larger studies. The objectives of this study were to evaluate predictors of self-reported fatigue in a Swedish nationwide register-based MS cohort. Methods: Using a repeated cross-sectional design, we included 2,165 persons

Björnståhls resa : Europa och Konstantinopel 1767–1779

Sommaren 1767 påbörjade orientalisten Jacob Jonas Björnståhl (1731–1779) en resa som förde honom till Frankrike, Schweiz, Italien, Tyskland, Holland och England innan han sjövägen tog sig till Konstantinopel och så småningom Grekland, där han avled i dysenteri vid 48 års ålder. Hade det inte varit för tidningsmannen Carl Christoffer Gjörwell hade eftervärlden aldrig fått någon större kännedom om d

Virtual participatory mapping of nature-based solutions in the Grande de Tárcoles River basin, Costa Rica : Connecting diverse knowledge systems in a context of physical immobility

Co-design processes are of key importance in planning and implementing Nature-based Solutions (NBS), but require boundary management between diverse holders of local, practical and scientific knowledge. Participatory and mapbased planning tools, such as Geodesign workshops, can facilitate such boundary management through mobilising knowledge holders, and translating and negotiating between differe

Monolithic InSb nanostructure photodetectors on Si using rapid melt growth

Monolithic integration of InSb on Si could be a key enabler for future electronic and optoelectronic applications. In this work, we report the fabrication of InSb metal-semiconductor-metal photodetectors directly on Si using a CMOS-compatible process known as rapid melt growth. Fourier transform spectroscopy demonstrates a spectrally resolved photocurrent peak from a single crystalline InSb nanost

Zwitterionic poly(terphenylene piperidinium) membranes for vanadium redox flow batteries

Over recent years, non-fluorinated ion exchange membranes based on poly(terphenylene) backbones carrying different functional groups have shown potential application for vanadium redox flow batteries (VRFBs). Generally, the ion exchange membrane in VRFBs is a critical component in terms of the output power, long-term stability and cost. Yet, the shortcomings of commercial membranes (e.g., Nafion)
