TL;DR: The beam energy and collision centrality dependence of the mean, standard deviation, skewness, and kurtosis of the net-proton multiplicity distributions in Au+Au collisions and the products of moments are found to be significantly below the Skellam expectation and close to expectations based on independent proton and antiproton production.
Abstract: We report the beam energy (root S-NN = 7.7-200 GeV) and collision centrality dependence of the mean (M), standard deviation (sigma), skewness (S), and kurtosis (kappa) of the net-proton multiplicity distributions in Au + Au collisions. The measurements are carried out by the STAR experiment at midrapidity (vertical bar y vertical bar < 0.5) and within the transverse momentum range 0.4 < p(T) < 0.8 GeV/c in the first phase of the Beam Energy Scan program at the Relativistic Heavy Ion Collider. These measurements are important for understanding the quantum chromodynamic phase diagram. The products of the moments, S sigma and K sigma(2), are sensitive to the correlation length of the hot and dense medium created in the collisions and are related to the ratios of baryon number susceptibilities of corresponding orders. The products of moments are found to have values significantly below the Skellam expectation and close to expectations based on independent proton and antiproton production. The measurements are compared to a transport model calculation to understand the effect of acceptance and baryon number conservation and also to a hadron resonance gas model.

TL;DR: Overall, four general recommendations were made: individualize therapeutic decisions, including whether to use antiparasitic drugs, based on the number, location, and viability of the parasites within the nervous system.
Abstract: Taenia solium neurocysticercosis is a common cause of epileptic seizures and other neurological morbidity in most developing countries. It is also an increasingly common diagnosis in industrialized countries because of immigration from areas where it is endemic. Its clinical manifestations are highly variable and depend on the number, stage, and size of the lesions and the host's immune response. In part due to this variability, major discrepancies exist in the treatment of neurocysticercosis. A panel of experts in taeniasis/cysticercosis discussed the evidence on treatment of neurocysticercosis for each clinical presentation, and we present the panel's consensus and areas of disagreement. Overall, four general recommendations were made: (i) individualize therapeutic decisions, including whether to use antiparasitic drugs, based on the number, location, and viability of the parasites within the nervous system; (ii) actively manage growing cysticerci either with antiparasitic drugs or surgical excision; (iii) prioritize the management of intracranial hypertension secondary to neurocysticercosis before considering any other form of therapy; and (iv) manage seizures as done for seizures due to other causes of secondary seizures (remote symptomatic seizures) because they are due to an organic focus that has been present for a long time.

TL;DR: In this article, the authors proposed indicators for measuring cement use efficiency, and presented a benchmark based on literature data and discusses potential gains in efficiency, including an increase in the efficiency of cement use.
Abstract: At present, the cement industry generates approximately 5% of the world’s anthropogenic CO2 emissions. This share is expected to increase since demand for cement based products is forecast to multiply by a factor of 2.5 within the next 40 years and the traditional strategies to mitigate emissions, focused on the production of cement, will not be capable of compensating such growth. Therefore, additional mitigation strategies are needed, including an increase in the efficiency of cement use. This paper proposes indicators for measuring cement use efficiency, presents a benchmark based on literature data and discusses potential gains in efficiency. The binder intensity (bi) index measures the amount of binder (kg m−3) necessary to deliver 1 MPa of mechanical strength, and consequently express the efficiency of using binder materials. The CO2 intensity index (ci) allows estimating the global warming potential of concrete formulations. Research benchmarks show that bi ∼5 kg m−3 MPa−1 are feasible and have already been achieved for concretes >50 MPa. However, concretes with lower compressive strengths have binder intensities varying between 10 and 20 kg m−3 MPa−1. These values can be a result of the minimum cement content established in many standards and reveal a significant potential for performance gains. In addition, combinations of low bi and ci are shown to be feasible.

TL;DR: In this paper, the authors extend Ball and Sheridan's analysis for a subset of 36 emerging market economies and find that, for them, the story is quite different, compared to non-targeters, developing countries adopting the IT regime not only experienced greater drops in inflation, but also in growth volatility.

TL;DR: Criteria for good assessment are outlined that include: (1) validity or coherence, (2) reproducibility or consistency, (3) equivalence, (4) feasibility, (5) educational effect, (6) catalytic effect, and (7) acceptability.
Abstract: In this article, we outline criteria for good assessment that include: (1) validity or coherence, (2) reproducibility or consistency, (3) equivalence, (4) feasibility, (5) educational effect, (6) catalytic effect, and (7) acceptability. Many of the criteria have been described before and we continue to support their importance here. However, we place particular emphasis on the catalytic effect of the assessment, which is whether the assessment provides results and feedback in a fashion that creates, enhances, and supports education. These criteria do not apply equally well to all situations. Consequently, we discuss how the purpose of the test (summative versus formative) and the perspectives of stakeholders (examinees, patients, teachers-educational institutions, healthcare system, and regulators) influence the importance of the criteria. Finally, we offer a series of practice points as well as next steps that should be taken with the criteria. Specifically, we recommend that the criteria be expanded or modified to take account of: (1) the perspectives of patients and the public, (2) the intimate relationship between assessment, feedback, and continued learning, (3) systems of assessment, and (4) accreditation systems.
