A global synthesis reveals biodiversity-mediated benefits for crop production
Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related ecosystem services can be maintained by a few dominant species or rely on high richness remains unclear. Using a global database from 89 studies (with 1475 locations), we partition the relative importance of species richness, abundance, and dominance for pollination; biological pest control; and final yields in the context of ongoing land-use change. Pollinator and enemy richness directly supported ecosystem services in addition to and independent of abundance and dominance. Up to 50% of the negative effects of landscape simplification on ecosystem services was due to richness losses of service-providing organisms, with negative consequences for crop yields. Maintaining the biodiversity of ecosystem service providers is therefore vital to sustain the flow of key agroecosystem benefits to society.

What can we learn from consumer reports on psychiatric adverse drug reactions with antidepressant medication? Experiences from reports to a consumer association
Background According to the World Health Organization (WHO) the cost of adverse drug reactions (ADRs) in the general population is high and under-reporting by health professionals is a well-recognized problem. Another way to increase ADR reporting is to let the consumers themselves report directly to the authorities. In Sweden it is mandatory for prescribers to report serious ADRs to the Medical Products Agency (MPA), but there are no such regulations for consumers. The non-profit and independent organization Consumer Association for Medicines and Health, KILEN has launched the possibility for consumers to report their perceptions and experiences from their use of medicines in order to strengthen consumer rights within the health care sector. This study aimed to analyze these consumer reports. Methods All reports submitted from January 2002 to April 2009 to an open web site in Sweden where anyone could report their experience with the use of pharmaceuticals were analyzed with focus on common psychiatric side effects related to antidepressant usage. More than one ADR for a specific drug could be reported. Results In total 665 reports were made during the period. 442 reports concerned antidepressant medications and the individual antidepressant reports represented 2392 ADRs and 878 (37%) of these were psychiatric ADRs. 75% of the individual reports concerned serotonin-reuptake inhibitor (SSRI) and the rest serotonin-norepinephrine reuptake inhibitor (SNRI). Women reported more antidepressant psychiatric ADRs (71%) compared to men (24%). More potentially serious psychiatric ADRs were frequently reported to KILEN and withdrawal symptoms during discontinuation were also reported as a common issue. Conclusions The present study indicates that consumer reports may contribute with important information regarding more serious psychiatric ADRs following antidepressant treatment. Consumer reporting may be considered a complement to traditional ADR reporting
Social and health epidemiology of immigrants in Germany: past, present and future
Razum O, Wenner J. Social and health epidemiology of immigrants in Germany: past, present and future. Public Health Reviews. 2016;37(1): 4.Germany has experienced different forms of immigration for many decades. At the end of and after the Second World War, refugees, displaced persons and German resettlers constituted the largest immigrant group. In the 1950s, labor migration started, followed by family reunification. There has been a constant migration of refugees and asylum seekers reaching peaks in the early 1990s as well as today. Epidemiological research has increasingly considered the health, and the access to health care, of immigrants and people with migration background. In this narrative review we discuss the current knowledge on health of immigrants in Germany. The paper is based on a selective literature research with a focus on studies using representative data from the health reporting system. Our review shows that immigrants in Germany do not suffer from different diseases than non-immigrants, but they differ in their risk for certain diseases, in the resources to cope with theses risk and regarding access to treatment. We also identified the need for differentiation within the immigrant population, considering among others social and legal status, country of origin and duration of stay. Though most of the studies acknowledge the need for differentiation, the lack of data currently rules out analyses accounting for the existing diversity and thus a full understanding of health inequalities related to migration to Germany
Overview of the TCV tokamak experimental programme
The tokamak a configuration variable (TCV) continues to leverage its
unique shaping capabilities, flexible heating systems and modern control
system to address critical issues in preparation for ITER and a fusion
power plant. For the 2019-20 campaign its configurational flexibility
has been enhanced with the installation of removable divertor gas
baffles, its diagnostic capabilities with an extensive set of upgrades
and its heating systems with new dual frequency gyrotrons. The gas
baffles reduce coupling between the divertor and the main chamber and
allow for detailed investigations on the role of fuelling in general
and, together with upgraded boundary diagnostics, test divertor and edge
models in particular. The increased heating capabilities broaden the
operational regime to include T (e)/T (i) similar to 1 and have
stimulated refocussing studies from L-mode to H-mode across a range of
research topics. ITER baseline parameters were reached in type-I ELMy
H-modes and alternative regimes with `small' (or no) ELMs explored. Most
prominently, negative triangularity was investigated in detail and
confirmed as an attractive scenario with H-mode level core confinement
but an L-mode edge. Emphasis was also placed on control, where an
increased number of observers, actuators and control solutions became
available and are now integrated into a generic control framework as
will be needed in future devices. The quantity and quality of results of
the 2019-20 TCV campaign are a testament to its successful integration
within the European research effort alongside a vibrant domestic
programme and international collaborations
Intrinsic limits on resolutions in muon- and electron-neutrino charged-current events in the KM3NeT/ORCA detector
Studying atmospheric neutrino oscillations in the few-GeV range with a
multimegaton detector promises to determine the neutrino mass hierarchy.
This is the main science goal pursued by the future KM3NeT/ORCA water
Cherenkov detector in the Mediterranean Sea. In this paper, the
processes that limit the obtainable resolution in both energy and
direction in charged-current neutrino events in the ORCA detector are
investigated. These processes include the composition of the hadronic
fragmentation products, the subsequent particle propagation and the
photon-sampling fraction of the detector. GEANT simulations of neutrino
interactions in seawater produced by GENIE are used to study the effects
in the 1-20 GeV range. It is found that fluctuations in the hadronic
cascade in conjunction with the variation of the inelasticity y are most
detrimental to the resolutions. The effect of limited photon sampling in
the detector is of significantly less importance. These results will
therefore also be applicable to similar detectors/media, such as those
in ice
Letter of intent for KM3NeT 2.0
The main objectives of the KM3NeT Collaboration are (i) the discovery
and subsequent observation of high-energy neutrino sources in the
Universe and (ii) the determination of the mass hierarchy of neutrinos.
These objectives are strongly motivated by two recent important
discoveries, namely: (1) the high-energy astrophysical neutrino signal
reported by IceCube and (2) the sizable contribution of electron
neutrinos to the third neutrino mass eigenstate as reported by Daya Bay,
Reno and others. To meet these objectives, the KM3NeT Collaboration
plans to build a new Research Infrastructure consisting of a network of
deep-sea neutrino telescopes in the Mediterranean Sea. A phased and
distributed implementation is pursued which maximises the access to
regional funds, the availability of human resources and the synergistic
opportunities for the Earth and sea sciences community. Three suitable
deep-sea sites are selected, namely off-shore Toulon (France), Capo
Passero (Sicily, Italy) and Pylos (Peloponnese, Greece). The
infrastructure will consist of three so-called building blocks. A
building block comprises 115 strings, each string comprises 18 optical
modules and each optical module comprises 31 photo-multiplier tubes.
Each building block thus constitutes a three-dimensional array of photo
sensors that can be used to detect the Cherenkov light produced by
relativistic particles emerging from neutrino interactions. Two building
blocks will be sparsely configured to fully explore the IceCube signal
with similar instrumented volume, different methodology, improved
resolution and complementary field of view, including the galactic
plane. One building block will be densely configured to precisely
measure atmospheric neutrino oscillations
