AI Article Synopsis
- Steering is a form of nonlocal correlation that is different from both Bell nonlocality and entanglement.
- The paper improves on previous steering criteria by incorporating a complete inferred-variance uncertainty relation using the Schrödinger-Robertson uncertainty relation (SRUR).
- The authors validate their new steering criterion by applying it to specific systems, namely discrete variable bipartite two-qubit and two-qutrit isotropic states.
Article Abstract
Steering is one of the three in-equivalent forms of nonlocal correlations intermediate between Bell nonlocality and entanglement. Schrödinger-Robertson uncertainty relation (SRUR), has been widely used to detect entanglement and steering. However, the steering criterion in earlier works, based on SRUR, did not involve complete inferred-variance uncertainty relation. In this paper, by considering the local hidden state model and Reid's formalism, we derive a complete inferred-variance EPR-steering criterion based on SRUR in the bipartite scenario. Furthermore, we check the effectiveness of our steering criterion with discrete variable bipartite two-qubit and two-qutrit isotropic states.

Multidimensional screen exposure and its impact on psychological well-being in toddlers.
Front Public Health
December 2024
Preventive Medicine and Health Education Department, School of Public Health, Fudan University, Shanghai, China.
Objective: Previous studies have indicated a link between screen exposure and children's mental health, but with the emergence of new screen media and a rise in screen content, uncertainties have grown. Our aim was to investigate the impact of screen use on psychological issues in 2- to 3-year-old children, considering screen time and types of screen media and content.
Methods: This cross-sectional study included participants from Shanghai, China, from February to July 2023.
On modes of disease transmission and the hidden shape of pandemics: A review of by Joshua Weitz.

The importance of asymptomatic transmission was a key discovery in our efforts to study and intervene in the COVID-19 pandemic. In (Johns Hopkins University Press, 2024), Joshua Weitz uses this aspect of SARS-CoV-2 natural history to discuss many counterintuitive characteristics of the pandemic. In this essay, I engage the arguments in the book, and discuss why asymptomatic transmission is such a critical dimension of the study of infectious diseases.

Introduction: In order to minimise physical interaction during the COVID-19 pandemic, telepsychiatry became a key part of clinical practice for many psychiatrists.
Methods: This study involved an exploratory, cross-sectional, opt-in online survey circulated to non-consultant doctors in psychiatry working in Ireland. It assessed experience and attitudes in relation to telepsychiatry use.

Centre for Evidence-Based Medicine and Health Care, Catholic University of Croatia, Zagreb, Croatia. ORCID: 0000-0002-8467-6061.
Objective: This study presents the personal experience of a 19-year-old student who fled the war in Ukraine, journeyed across multiple countries, and ultimately enrolled in a university psychology program in Croatia.
Methods: A collaborative autoethnographic approach was employed to explore the student's experience as a war refugee, traversing Europe, and beginning university life in a foreign country. Data were collected through the student's reflective writing.
Global, regional, and national epidemiology of childhood neuroblastoma (1990-2021): a statistical analysis of incidence, mortality, and DALYs.
EClinicalMedicine
January 2025
Department of Pediatric Surgery, The First Affiliated Hospital of Guangxi Medical University, Nanning, 530021, Guangxi Zhuang Autonomous Region, PR China.
Background: Neuroblastoma is the most prevalent extracranial solid tumor in pediatric populations worldwide, representing 8-10% of childhood malignancies and contributing to approximately 15% of pediatric cancer-related fatalities. This study aims to report global trends in the incidence, mortality, and disability-adjusted life years (DALYs) of childhood neuroblastoma from 1990 to 2021.
Methods: The study utilized data from the Global Burden of Disease (GBD) database to analyze neuroblastoma incidence, mortality, and DALYs in children aged 0-14 years.
