This randomized, open label, single-center trial included Chinese adults who have received two-dose CoronaVac randomized to low-dose or high-dose aerosolised Ad5-nCoV group, or CoronaVac group. In this report, we mainly evaluated the geometric mean titres (GMTs) of neutralising antibodies (NAbs)...

Cognitive Diagnosis Testlet Model for Multiple-Choice Items

Lei Guo, Wenjie Zhou & Xiao Li
Testlet design is very popular in educational and psychological assessments. This article proposes a new cognitive diagnosis model, the Multiple-Choice Cognitive Diagnostic Testlet (MC-CDT) model for a test with testlets consisting of multiple-choice (MC) items. The MC-CDT model uses the original examinees' responses to MC items instead of dichotomously scored data (i.e. correct or incorrect) to retain the information from different distractors and thus enhance the MC items' diagnostic power. The MCMC algorithm is adopted...

Highly pathogenic avian influenza virus (HPAIV) such as H5N1, H5N6, and H7N9 have been reported to frequently infect human, but acute encephalitis caused by HPAIV in human have been rarely reported. We report the first critical case of acute encephalitis with mild pneumonia caused by H5N6 virus. On January 25 of 2022, a 6-year-old girl with severe neurological symptoms was admitted to our hospital and rapidly developed to seizures and coma. Brain imaging showed abnormalities....

Effect of acute acidic stress on survival and metabolic activity of zooplankton from Lake Biwa, Japan

Huanan Gao, Xin Liu & Syuhei Ban
Acute acidic stress from sources such as acid rain might impact on lake ecosystems in many aspects. Because zooplankton is sensitive to environmental change, it could be a good biotic indicator of the effects of acidification. We investigated survival and metabolic rates of three dominant zooplankton taxa in Lake Biwa, the cladoceran Daphnia pulicaria, and the copepods Eodiaptomus japonicus and Cyclopoida spp., when subjected to different pH values (pH 4.0−8.0) at low (10 °C) and...

Coxsackievirus A10 (CV-A10) has become one of the major pathogens of hand, foot and mouth disease (HFMD), and studies on the vaccine and animal model of CV-A10 are still far from complete. Our study used a mouse adapted CV-A10 strain, which was lethal for 14-day-old mice, to develop an infected mouse model. Then this model was employed to establish an actively immunized-challenged mouse model to evaluate the efficacy of a formaldehyde-inactivated CV-A10 vaccine, which was...

Getting the ROC into Sync

Liu Yang, Kajal Lahiri & Adrian Pagan
Judging the conformity of binary events in macroeconomics and finance has often been done with indices that measure synchronization. In recent years, the use of Receiver Operating Characteristic (ROC) curve has become popular for this task. This paper shows that the ROC and synchronization approaches are closely related, and each can be derived from a decision-making framework. Furthermore, the resulting global measures of the degree of conformity can be identified and estimated using the standard...
