Fundamentals of Sports Analytics

Recently, the importance of statistics and analytics in sports has increased. This review describes measures of sports injury and fundamentals of sports injury research with a brief overview of some of the emerging measures of sports performance. We describe research study designs that can be used to identify risk factors for injury, injury surveillance programs, and common measures of injury risk and association. Finally, we describe measures of physical performance and training and considerations for using these measures. This review provides sports medicine clinicians with an understanding of current research measures and considerations for designing sports injury research studies

Assessing Butterflies in Europe. Executive summary

1. The Assessing Butterflies in Europe (ABLE) project was an EU Parliamentary Pilot project with a duration of two years (beginning of December 2019 to the end of November 2020) and received €800,000 of funding via a service contract with Directorate General Environment. 2. The mandate and rationale from the EU Parliament was: “The project aims at developing a suite of EU Lepidoptera indicators which can help improve conservation measure and assess progress in implementing EU policies and legislation such as the EU Biodiversity Strategy to 2020 and the EU Habitats Directive. Besides providing a highly relevant indicator for measuring progress in terms of managing and restoring Natura 2000 sites, it would also contribute to monitoring progress on Target 3 of the EU Biodiversity Strategy, which aims to increase the contribution of agriculture and forestry to maintaining and enhancing biodiversity. In particular, the pilot should deliver a representative indicator to help monitor the impact of the Common Agricultural Policy on grassland biodiversity. It will also provide data to produce a climate change indicator, thereby contributing to the ongoing revision of climate change adaptation strategies. Indicators will also be possible for woodland, wetland and urban habitats.” 3. The ABLE project was delivered by a consortium of the UK Centre for Ecology & Hydrology, Butterfly Conservation Europe, Butterfly Conservation UK, De Vlinderstichting and HelmholtzZentrum für Umweltforschung GmbH – UFZ. Considerable in-kind contributions were provided by Butterfly Conservation partners across Europe. 4. There is mounting evidence of widespread declines in the diversity and abundance of insects across the globe. The ABLE project is particularly timely in helping to develop capacity for monitoring of insects and assessing the status of butterflies in the EU. 5. There are 482 butterfly species in Europe (451 occurring within the EU27), breeding in a wide range of habitats. Butterflies react quickly to change and are considered to be good biological indicators, especially of other insects and pollinators. Monitoring butterflies can help shed light on changes in these important groups. 6. The main aims of the ABLE project were to collate butterfly monitoring data across Europe, to facilitate the start of new schemes in the EU, and to develop indicators to help policy design and evaluation. 7. Following the mandate from the EU Parliament for this Pilot project, we make the following key recommendations: i. Use Butterfly Monitoring Scheme (eBMS) data and indicators for EU policy design; to inform resource planning, especially for Member State’s Prioritised Action Frameworks (PAFs); and to track, evaluate and adjust EU and MSs policy implementation, including the EU Green Deal, EU Biodiversity Strategy 2030 and the EU Farm to Fork Strategy, to help reverse pollinator declines. ii. Use Member State and Article 17 data on butterflies to inform the design, implementation and evaluation of the EU CAP and MS’s CAP Strategic Plans; to ensure Forestry plans include more grassland refuges and herb rich rides and edges; and that urban planning and regional developments invest in pollinator habitats. Butterfly Conservation Europe 2020 \textbar ASSESSING BUTTERFLIES IN EUROPE – EXECUTIVE SUMMARY 6 iii. Use available Butterfly Monitoring Scheme data to strengthen the quality of assessments of conservation Status of Habitats Directive listed habitats and species in meeting mandatory reporting requirements under Art 17 of the Directive iv. Invest in linking butterfly data with land use and management data, including implementation of Natura 2000 Management Plans, Land Parcel Information system and Satellite data to help evaluate conservation effectiveness v. Support additional monitoring of rare and vulnerable butterflies (including endemics and those not listed on the Habitats Directive) and designate some additional Protected Areas to sustain and enhance the quality of remaining areas that are important for these Red Listed butterflies and so prevent further extinctions vi. Invest in further capacity building and cooperation among citizen scientists, professionals, farmers and authorities to monitor and record abundance of butterflies, moths and other pollinators, including supporting coordination, training and growth of citizen science eBMS schemes (as recommended by EU Pollinator Expert Group); filling data gaps and developing tools and expertise to gather and integrate data from various sources. vii. ABLE shows that Citizen Science eBMS are cost effective, delivering very good value for money. New citizen science Butterfly Monitoring Schemes are needed in Denmark, Greece, Latvia, Romania and Slovakia. Together with further support to sustain and increase transects across most EU MSs, especially in the ten schemes newly created during the ABLE project. The ten EU27 countries where new Citizen Science butterfly monitoring schemes were begun in 2019/2020, with the support of ABLE, BCE partners and active volunteers, are Austria, Bulgaria, Croatia, Cyprus, Czech Republic, Hungary, Italy, Malta, Poland and Portugal. Together with Belgium, Estonia, Finland, France, Germany, Ireland, Luxemburg, Lithuania (currently dormant), Netherlands, Slovenia, Spain, Sweden, there are now 22 EU(27) Member States with butterfly monitoring schemes. With several more outside the EU, including Norway, Switzerland and the UK (which has the longest running scheme). 8. This Executive Summary accompanies detailed technical reports on the three project tasks: development of butterfly indicators, development of butterfly monitoring networks, and tools to support butterfly monitoring and analysis

From the Big Bang Theory to the Theory of a Stationary Universe

We consider chaotic inflation in the theories with the effective potentials phi^n and e^{\alpha\phi}. In such theories inflationary domains containing sufficiently large and homogeneous scalar field \phi permanently produce new inflationary domains of a similar type. We show that under certain conditions this process of the self-reproduction of the Universe can be described by a stationary distribution of probability, which means that the fraction of the physical volume of the Universe in a state with given properties (with given values of fields, with a given density of matter, etc.) does not depend on time, both at the stage of inflation and after it. This represents a strong deviation of inflationary cosmology from the standard Big Bang paradigm. We compare our approach with other approaches to quantum cosmology, and illustrate some of the general conclusions mentioned above with the results of a computer simulation of stochastic processes in the inflationary Universe.Comment: No changes to the file, but original figures are included. They substantially help to understand this paper, as well as eternal inflation in general, and what is now called the "multiverse" and the "string theory landscape."

Strange Meson Enhancement in PbPb Collisions

The NA44 Collaboration has measured yields and differential distributions of K+, K-, pi+, pi- in transverse kinetic energy and rapidity, around the center-of-mass rapidity in 158 A GeV/c Pb+Pb collisions at the CERN SPS. A considerable enhancement of K+ production per pi is observed, as compared to p+p collisions at this energy. To illustrate the importance of secondary hadron rescattering as an enhancement mechanism, we compare strangeness production at the SPS and AGS with predictions of the transport model RQMD.Comment: 11 pages, including 4 figures, LATE

Spherically Symmetric Braneworld Solutions with R_{4} term in the Bulk

An analysis of a spherically symmetric braneworld configuration is performed when the intrinsic curvature scalar is included in the bulk action; the vanishing of the electric part of the Weyl tensor is used as the boundary condition for the embedding of the brane in the bulk. All the solutions outside a static localized matter distribution are found; some of them are of the Schwarzschild-(A)dS_{4} form. Two modified Oppenheimer-Volkoff interior solutions are also found; one is matched to a Schwarzschild-(A)dS_{4} exterior, while the other does not. A non-universal gravitational constant arises, depending on the density of the considered object; however, the conventional limits of the Newton's constant are recovered. An upper bound of the order of TeV for the energy string scale is extracted from the known solar system measurements (experiments). On the contrary, in usual brane dynamics, this string scale is calculated to be larger than TeV.Comment: 23 pages, 1 figure, one minor chang

Lattice gauge theory with baryons at strong coupling

We study the effective Hamiltonian for strong-coupling lattice QCD in the case of non-zero baryon density. In leading order the effective Hamiltonian is a generalized antiferromagnet. For naive fermions, the symmetry is U(4N_f) and the spins belong to a representation that depends on the local baryon number. Next-nearest-neighbor (nnn) terms in the Hamiltonian break the symmetry to U(N_f) x U(N_f). We transform the quantum problem to a Euclidean sigma model which we analyze in a 1/N_c expansion. In the vacuum sector we recover spontaneous breaking of chiral symmetry for the nearest-neighbor and nnn theories. For non-zero baryon density we study the nearest-neighbor theory only, and show that the pattern of spontaneous symmetry breaking depends on the baryon density.Comment: 31 pages, 5 EPS figures.

Heavy quarkonium: progress, puzzles, and opportunities

A golden age for heavy quarkonium physics dawned a decade ago, initiated by the confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of related experimental activity. The early years of this period were chronicled in the Quarkonium Working Group (QWG) CERN Yellow Report (YR) in 2004, which presented a comprehensive review of the status of the field at that time and provided specific recommendations for further progress. However, the broad spectrum of subsequent breakthroughs, surprises, and continuing puzzles could only be partially anticipated. Since the release of the YR, the BESII program concluded only to give birth to BESIII; the $B$-factories and CLEO-c flourished; quarkonium production and polarization measurements at HERA and the Tevatron matured; and heavy-ion collisions at RHIC have opened a window on the deconfinement regime. All these experiments leave legacies of quality, precision, and unsolved mysteries for quarkonium physics, and therefore beg for continuing investigations. The plethora of newly-found quarkonium-like states unleashed a flood of theoretical investigations into new forms of matter such as quark-gluon hybrids, mesonic molecules, and tetraquarks. Measurements of the spectroscopy, decays, production, and in-medium behavior of c\bar{c}, b\bar{b}, and b\bar{c} bound states have been shown to validate some theoretical approaches to QCD and highlight lack of quantitative success for others. The intriguing details of quarkonium suppression in heavy-ion collisions that have emerged from RHIC have elevated the importance of separating hot- and cold-nuclear-matter effects in quark-gluon plasma studies. This review systematically addresses all these matters and concludes by prioritizing directions for ongoing and future efforts.Comment: 182 pages, 112 figures. Editors: N. Brambilla, S. Eidelman, B.
