DataM – Biomass estimates (v3): a new database to quantify biomass availability in the European Union
In 2012, the Communication of the European Commission "Innovating for Sustainable Growth: A Bioeconomy for Europe" (COM(2012)60) has put the development of the Bioeconomy at the forefront, as a way of reconciling economic growth and the green economy. But current official statistics fall short in providing relevant data to document this new concept. The establishment of the bioeconomy observatory (BISO) aims at filling this gap, compiling qualitative and quantitative data of relevance for policy makers. Considering that biomass is the raw material of the bioeconomy, JRC-IPTS together with the Nova- Institute has elaborated in the BISO framework a new database that quantifies the production and residues of biomass: DataM – Biomass estimates. Compared to existing databases like Eurostat-MFA (env_ac_mfa) and SERI Global material flows, this new database presents a higher level of disaggregation at the geographical and commodity level. Moreover, it allows gathering data either into fresh or dry matter. This database is stored in DataM, a JRC data management tool, and is accessible via two applications: the full version in datamintracomm for all European commission staff, and a public light version online datamweb. Apart from offering a quantification of crop biomass and residues at European level, these two applications also allows browsing data at member state and commodity level. A quantification of the European trade and biomass uses in biomass equivalent is foreseen in next versions, together with the integration of woody and aquatic product.JRC.J.4-Agriculture and Life Sciences in the Econom
Prognostic factors for relapse in patients with clinical stage I testicular non-seminoma: A nationwide, population-based cohort study
BACKGROUND: Approximately 30% of patients with clinical stage I non-seminoma (CSI-NS) relapse. Current risk stratification is based on lymphovascular invasion (LVI) alone. The extent to which additional tumor characteristics can improve risk prediction remains unclear.OBJECTIVE: To determine the most important prognostic factors for relapse in CSI-NS patients.DESIGN, SETTING, AND PARTICIPANTS: Population-based cohort study including all patients with CSI-NS diagnosed in Denmark between 2013 and 2018 with follow-up until 2022. Patients were identified in the prospective Danish Testicular Cancer database. By linkage to the Danish National Pathology Registry, histological slides from the orchiectomy specimens were retrieved.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Histological slides were reviewed blinded to the clinical outcome. Clinical data were obtained from medical records. The association between prespecified potential prognostic factors and relapse was assessed using Cox regression analysis. Model performance was evaluated by discrimination (Harrell's C-index) and calibration.RESULTS: Of 453 patients included, 139 patients (30.6%) relapsed during a median follow-up of 6.3 years. Tumor invasion into the hilar soft tissue of the testicular hilum, tumor size, LVI and embryonal carcinoma were independent predictors of relapse. The estimated 5-year risk of relapse ranged from < 5% to > 85%, depending on the number of risk factors. After internal model validation, the model had an overall concordance statistic of 0.75. Model calibration was excellent.CONCLUSION AND RELEVANCE: The identified prognostic factors provide a much more accurate risk stratification than current clinical practice, potentially aiding clinical decision-making.</p
Assessing the Bioeconomy's Contribution to Evidence-Based Policy: A Comparative Analysis of Value Added Measurements
As the bioeconomy has gained importance in European policy agendas, several European research institutes have elaborated ad hoc methodologies to measure the size of the European bioeconomy and aid in the monitoring of its performance. This paper reviews the main approaches found in the literature for such a quantification by comparing the different methodologies and the corresponding quantitative findings. The various estimations published might be confusing at first sight, reporting a value added of the European bioeconomy within the large range of EUR 881 billion to EUR 2.3 trillion. However, the study concludes that each approach is best suited to measuring a different aspect of the bioeconomy. Using the different approaches, we estimate that the markets of bio-based products and energy generate EUR 730-790 billion of value added, the use of biomass within the European economy generates EUR 670 billion of value added, and the sourcing of core bioeconomy industries with goods and services generates EUR 270 billion of value added. There is no evidence of an increased use of biomass inputs in EU industries in substitution of fossil resources, nor of a decreasing dependence of traditional bioeconomy industries towards fossil resources over the period 2005-2015.Bioeconomyvalue addedEuropeinput-output tablesbio-based industriesmethodologiesPublishe
The placebo effect and its determinants in fibromyalgia: meta-analysis of randomized controlled trials
The aims of this study were to determine whether placebo treatment in randomised controlled trials (RCTs) is effective for fibromyalgia and to identify possible determinants of the magnitude of any such placebo effect. A systematic literature search was undertaken for RCTs in people with fibromyalgia that included a placebo and/or a no-treatment (observation only or waiting list) control group. Placebo effect size (ES) for pain and other outcomes was measured as the improvement of each outcome from baseline divided by the standard deviation of the change from baseline. This effect was compared with changes in the no-treatment control groups. Meta-analysis was undertaken to combine data from different studies. Subgroup analysis was conducted to identify possible determinants of the placebo ES. A total of 3912 studies were identified from the literature search. After scrutiny, 229 trials met the inclusion criteria. Participants who received placebo in the RCTs experienced significantly better improvements in pain, fatigue, sleep quality, physical function, and other main outcomes than those receiving no treatment. The ES of placebo for pain relief was clinically moderate (0.53, 95%CI 0.48 to 0.57). The ES increased with increasing strength of the active treatment, increasing participant age and higher baseline pain severity, but decreased in RCTS with more women and with longer duration of fibromyalgia. In addition, placebo treatment in RCTs is effective in fibromyalgia. A number of factors (expected strength of treatment, age, gender, disease duration) appear to influence the magnitude of the placebo effect in this condition
Multidifferential study of identified charged hadron distributions in -tagged jets in proton-proton collisions at 13 TeV
Jet fragmentation functions are measured for the first time in proton-proton
collisions for charged pions, kaons, and protons within jets recoiling against
a boson. The charged-hadron distributions are studied longitudinally and
transversely to the jet direction for jets with transverse momentum 20 GeV and in the pseudorapidity range . The
data sample was collected with the LHCb experiment at a center-of-mass energy
of 13 TeV, corresponding to an integrated luminosity of 1.64 fb. Triple
differential distributions as a function of the hadron longitudinal momentum
fraction, hadron transverse momentum, and jet transverse momentum are also
measured for the first time. This helps constrain transverse-momentum-dependent
fragmentation functions. Differences in the shapes and magnitudes of the
measured distributions for the different hadron species provide insights into
the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any
