Reexamination of Yuknessia from the Cambrian of China and first report of Fuxianospira from North America

Yuknessia Walcott, 1919 recently was transferred from the green algae to the Phylum Hemichordata on the basis of new details observed for the type species, Y. simplex, from the Burgess Shale Formation (Cambrian Stage 5) of British Columbia. This has prompted reexamination of material attributed to Yuknessia from various Cambrian localities in South China. Findings preclude both a Yuknessia and a h

Work Motivating Factors in Rehabilitation: A Brief Review

Motivation can be defined as everything that drives and sustains human behaviour. The identification and use of each patient's motivational factors in the rehabilitation process has been shown to be important for a successful rehabilitation outcome. The aim of this literature review is to identify factors related to high work motivation. The databases Medline and Psychlit were searched for factors

A 38pJ/b Optimal Soft-MIMO Detector

An optimal soft multiple-input multiple-output (MIMO) detector is proposed with linear complexity for a general spatial multiplexing system with two transmitting symbols and NR ≥ 2 receiving antennas. The computational complexity of the proposed scheme is independent of the operating signal-tonoise ratio (SNR) and grows linearly with the constellation order. It provides the soft maximum-likelihood

Forty years of midwinter Counts of waterfowl along the Coasts of Scania, South Sweden.

The International Midwinter Counts, organised byWetlands International, started in January 1967, butco-ordinated counts were organised along the coastsof Scania, south Sweden, already since January 1964.This paper summarises the results of the first fortyyears. During the first years full coverage was attained,but in later years the counts covered nine larger areas,containing about 75% of all wate

Incidence and familial risk of pleural mesothelioma in Sweden : A national cohort study

Familial clustering of pleural mesothelioma was reported previously, but none of the reports quantified the familial risk of mesothelioma or the association with other cancers. The contributions of shared environmental or genetic factors to the aggregation of mesothelioma were unknown. We used a number of Swedish registers, including the Swedish Multigeneration Register and the Swedish Cancer Regi

Long-term trends and Changes in numbers and distribution of some wintering waterfowl species along the Swedish Baltic coast.

Regular counts of wintering waterfowl have been undertaken as a part of the International Waterfowl Census (IWC) and the National Swedish Environmental Monitoring Program since 1964. After the first years, a network of annually surveyed sites was established for the calculation of annual indices. Country-wide surveys (also including aerial counts) were undertaken 1971–1974, 1987–1989, 1992–1993 (p

Ergodicity of age-dependent inventory control systems

We consider continuous review inventory systems with general doubly stochastic Poisson demand. In this specific case the demand rate, experienced by the system, varies as a function of the age of the oldest unit in the system. It is known that the stationary distributions of the ages in such models often have a strikingly simple form. In particular, they exhibit a typical feature of a Poisson proc

The Drivers of Long-run CO₂ emissions in Europe, North America and Japan since 1800

Using an extended Kaya decomposition, we identify the drivers of long-run CO₂ emissions since 1800 for Denmark, France, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, the UK, the United States, Canada and Japan. By considering biomass and carbon-free energy sources along with fossil fuels, we are able to shed light on the effects of past and present energy transitions on CO₂ emissions.

Production and use of regional climate model projections – A Swedish perspective on building climate services

We describe the process of building a climate service centred on regional climate model results from the Rossby Centre regional climate model RCA4. The climate service has as its central facility a web service provided by the Swedish Meteorological and Hydrological Institute where users can get an idea of various aspects of climate change from a suite of maps, diagrams, explaining texts and user g

Does early-life diet affect longevity? A meta-analysis across experimental studies

Life-history theory predicts that nutrition influences lifespan owing to tradeoffs between allocating resources to reproduction, growth and repair. Despite occasional reports that early diet has strong effects on lifespan, it is unclear whether this prediction is generally supported by empirical studies. We conducted a meta-analysis across experimental studies manipulating pre- or post-natal diet

The neurological wake-up test increases stress hormone levels in patients with severe traumatic brain injury

OBJECTIVES: The "neurological wake-up test" is needed to evaluate the level of consciousness in patients with severe traumatic brain injury. However, the neurological wake-up test requires interruption of continuous sedation and may induce a stress response and its use in neurocritical care is controversial. We hypothesized that the neurological wake-up test induces an additional biochemical stres
