Individual-based simulation of the spatial and temporal dynamics of macroinvertebrate functional groups provides insights into benthic community assembly mechanisms

The complexity and scales of the processes that shape communities of marine benthic macroinvertebrates has limited our understanding of their assembly mechanisms and the potential to make projections of their spatial and temporal dynamics. Individual-based models can shed light on community assembly mechanisms, by allowing observed spatiotemporal patterns to emerge from first principles about the

Multi-ethnic genome-wide association study for atrial fibrillation

Atrial fibrillation (AF) affects more than 33 million individuals worldwide1 and has a complex heritability2. We conducted the largest meta-analysis of genome-wide association studies (GWAS) for AF to date, consisting of more than half a million individuals, including 65,446 with AF. In total, we identified 97 loci significantly associated with AF, including 67 that were novel in a combined-ancest

Automatic hand phantom map generation and detection using decomposition support vector machines

Background: There is a need for providing sensory feedback for myoelectric prosthesis users. Providing tactile feedback can improve object manipulation abilities, enhance the perceptual embodiment of myoelectric prostheses and help reduce phantom limb pain. Many amputees have referred sensation from their missing hand on their residual limbs (phantom maps). This skin area can serve as a target for

Scheimpflug Lidar for combustion diagnostics

A portable Lidar system developed for large-scale (~1-20 m) combustion diagnostics is described and demonstrated. The system is able to perform remote backscattering measurements with range and temporal resolution. The range resolution is obtained by sharply imaging a part of the laser beam onto a CMOS-array or ICCD detector. The large focal depth required to do this is attained by placing the las

The Challenges of Re-Packaging a Heritage

In the last decade, many museums that were established in the 20th century by immigrants from the Nordic countries have become increasingly concerned with broadening their audiences and more actively engaging their visitors. Efforts to do this have varied from offering cocktail hours, culinary conferences, and sauna sessions, to striving to appeal to people who may not identify as Nordic or do not

Frank Ramsey (1903-1930)

Frank Plumpton Ramsey (1903-1930), British mathematician and philosopher, best known for his work on the foundations of mathematics. But Ramsey also made remarkable contributions to epistemology, semantics, logic, philosophy of science, mathematics, statistics, probability and decision theory, economics and metaphysics.

The predictive role of ultrasound-detected tenosynovitis and joint synovitis for flare in patients with rheumatoid arthritis in stable remission. Results of an Italian multicentre study of the Italian Society for Rheumatology Group for Ultrasound : The STARTER study

Objective: To define the role of ultrasound (US) for the assessment of patients with rheumatoid arthritis (RA) in clinical remission, including joint and tendon evaluation. Methods: A multicentre longitudinal study has been promoted by the US Study Group of the Italian Society for Rheumatology. 25 Italian centres participated, enrolling consecutive patients with RA in clinical remission. All patie

Genesis of hummocks found in tunnel valleys : an example from Hörda, southern Sweden

In the south-central sector of the former Fennoscandian Ice Sheet, imprints of the sub-glacial hydrological system are present as “glaciofluvial corridors,” formed by glacial meltwater at the ice–bed interface during the Bølling–Allerød warm period. Many of these are interpreted as tunnel valleys and are commonly characterized by hummocks on their valley floors. Contemporary ice sheets produce inc

Expression of programmed cell death protein 1 (PD-1) and its ligand PD-L1 in colorectal cancer : Relationship with sidedness and prognosis

Expression of programmed cell death protein 1 (PD-1) and its ligand PD-L1 has been demonstrated to confer a prognostic value in colorectal cancer (CRC), but no studies have investigated whether this association differs according to tumour location. In this study, immunohistochemical expression of PD-1 and PD-L1 was analysed in tissue microarrays with primary tumours from 557 incident CRC cases fro

ESS Personnel Safety Systems Test Stand

Providing and assuring safe conditions for personnel is a key parameter required to operate the European Spallation Source (ESS). The Personnel Safety System (PSS) primarily prevent workers from the facility's ionising radiation hazards, but also identify as well as mitigate against all other hazards such as high voltage and oxygen depletion. The PSS test stand is being developed in the ESS Protec

Low-resolution vision in a velvet worm (Onychophora)

Onychophorans, also known as velvet worms, possess a pair of simple lateral eyes, and are a key lineage with regard to the evolution of vision. They resemble ancient Cambrian forms, and are closely related to arthropods, which boast an unrivalled diversity of eye designs. Nonetheless, the visual capabilities of onychophorans have not been well explored. Here, we assessed the spatial resolution of

Human capital sorting : The “when” and “who” of the sorting of educated workers to urban regions

The sorting of high-ability workers is often advanced as one source of spatial disparities in economic outcomes. There are still few papers that analyze when human capital sorting occurs and whom it involves. Using data on 16 cohorts of university graduates in Sweden, we demonstrate significant sorting to urban regions on high school grades and education levels of parents, i.e., two attributes typ
