A parts-per-billion measurement of the antiproton magnetic moment

2017

The magnetic moment of the antiproton is measured at the parts-per-billion level, improving on previous measurements by a factor of about 350. Comparing the fundamental properties of normal-matter particles with their antimatter counterparts tests charge–parity–time (CPT) invariance, which is an important part of the standard model of particle physics. Many properties have been measured to the parts-per-billion level of uncertainty, but the magnetic moment of the antiproton has not. Christian Smorra and colleagues have now done so, and report that it is −2.7928473441 ± 0.0000000042 in units of the nuclear magneton. This is consistent with the magnetic moment of the proton, 2.792847350 ± 0.0…

Alignment between standardized assessments and academic standards : the case of the Saber Mathematics Test in Colombia

2013

Resumen basado en el de la publicación Título, resumen y palabras clave en español e inglés Disponible la versión en inglés Análisis del concepto de alineación presentando los resultados de un estudio que examina el grado de alineación entre una evaluación estandarizada de matemáticas y unos estándares académicos. La alineación se examina usando el modelo de Webb y los resultados sugieren que el grado de alineación entre las evaluaciones estandarizadas y los estándares académicos no es el más adecuado y por lo tanto los resultados se deben interpretar con mucha cautela y se debe poner mucho cuidado con el tipo de decisiones que se toman con base en los resultados.

Solvent-Independent Electrode Potentials of Solids Undergoing Insertion Electrochemical Reactions: Part III. Experimental Data for Prussian Blue Unde…

2012

Prussian blue-modified electrodes immersed in K+-containing solutions can be used to obtain a solvent-independent redox potential system. On the basis of theoretical modeling of diffusion processes occurring under the conditions of voltammetry of immobilized particles, voltammetric and chronoamperometric data can be combined to obtain solvent-independent electrode potentials for the K+-assisted one-electron reduction of Prussian blue to Berlin white. Data for water, MeOH, EtOH, MeCN, DMS, DMF, and NM are provided.

Quantification of electrochromic kinetics by analysis of RGB digital video images

2018

A new, rapid, and practical procedure to obtain quantitative kinetic information of electrochromic materials is proposed. When the transition between two colors on a colored electrode surface is monitorized by digital video, the analysis of pixel color intensity (I) in sequential RGB digital images allows us to precise the half-life time (t1/2) of the color change since a maximum value of the standard deviation of the pixel intensity (σ(I)) is reached. We simulated and analyzed the evolution of standard deviation during an electrochromic transition in different circumstances (kinetic and diffusion control). As an example of application, electrochromic transitions of a thin film model, the P…

A Multicentre, Randomised, Controlled Trial of a Combined Clinical Treatment for First-Episode Psychosis

2021

Introduction: There is evidence that early intervention contributes to improving the prognosis and course of first-episode psychosis (FEP). However, further randomised treatment clinical trials are needed. Objectives: The aim of this study was to compare the efficacy of a combined clinical treatment involving Cognitive Behavioural Therapy (CBT) as an adjunctive to treatment-as-usual (TAU) (CBT+TAU) versus TAU alone for FEP. Patients and methods: In this multicentre, single-blind, randomised controlled trial, 177 participants were randomly allocated to either CBT+TAU or TAU. The primary outcome was post-treatment patient functioning. Results: The CBT+TAU group showed a greater improvement in…

Calcifying zooplankton standing stocks and in the North Pacific from the R/V Kilo Moana cruise KM1712

2022

This dataset compiles the standing stocks (ind/m³), the integrated standing stocks (ind/m²) and the integrated CaCO3 standing stocks (mg/m²) for three groups of zooplanktonic calcifying organisms: pteropods, heteropods and foraminifers. The organisms were collected by oblique towing (Ø 0.5 m, 90 μm mesh size, SeaGear mechanical flowmeter) in the North Pacific between Hawaii and the Gulf of Alaska during the R/V Kilo Moana cruise KM1712 in August 2017. The sampling strategy was designed to capture an integrated sample of all foraminifers, pteropods and heteropods from juveniles to adults living throughout the upper water column. Pteropods and heteropods were quantified and shell diameter mea…

Tax Burden, as Determining Factor of Tax Morale in Romania and European Union

2020

Tax burden and tax morale are economic variables that influence each other. Tax morale is one of the basic components of compliance decisions and fiscal pressure expresses the intensity with which revenue from taxpayers is collected from individuals and legal persons. The tax morale determines the taxpayer to voluntarily comply with the declaration and payment of taxes due to the budget. Any form of collection, other than voluntary compliance, entails additional costs that implicitly increase budget expenditures, and consequently reduce the standard of living. The creation and proper functioning of a control system, as well as voluntary compliance are imperative for achieving a high level o…

In an ideal world who should carry the can for wrongdoing business?

2018

Purpose This paper aims to analyze the main international rules against economic crime and to verify if Italian legislation provides for appropriate measures according to own needs at a national level. Design/methodology/approach The research uses a comparative approach by examining the existing legislations on a global, European and Italian level for finding analogies and differences between them. Findings The research has discovered a wide variation in the legislative interventions against economic crimes and in the kind of imposed sanctions. Nevertheless, there seems to be a trend toward penalties, with a high degree of uniformity between the different levels of protection. Research lim…

Prediction of bleeding events in patients with venous thromboembolism on stable anticoagulation treatment.

2016

Attempts at identifying patients with an elevated risk of bleeding while on anticoagulation following acute venous thromboembolism (VTE) have largely been unsuccessful thus far. We sought to develop a clinical prediction score for bleeding during stable anticoagulation treatment after acute VTE.We performed a post hoc analysis of the pooled RE-COVER studies, two double-blind randomised “sister” trials evaluating dabigatran versus standard treatment in 5107 VTE patients.A score was derived from patients randomised to dabigatran using logistic regression analysis covering the complete follow-up period. The final model, named VTE-BLEED, included six variables and yielded a c-statistic of 0.72 …
