A search for time-integrated CP violation in D(0)→h(-)h(+) (h=K, π) decays is presented using 0.62 fb(-1) of data collected by LHCb in 2011. The flavor of the charm meson is determined by the charge of the slow pion in the D(*+)→D(0)π(+) and D(*-)→D[over ¯](0)π(-) decay chains. The difference in CP asymmetry between D(0)→K(-)K(+) and D(0)→π(-)π(+), ΔA(CP)≡A(CP)(K(-)K(+))-A(CP)(π(-)π(+)), is measured to be [-0.82±0.21(stat)±0.11(syst)]%. This differs from the hypothesis of CP conservation by 3.5 standard deviations.

The presence of a doping substance in an athlete's biological sample may not be only related to intentional pharmacological support. The unintended use of a prohibited substance may be due various reasons. This paper describes the case of a Polish canoeist preparing for the 2024 Summer Olympics in Paris who presented a positive doping test result, as a consequence of administering medication to her injured dog.

The perspective article explores systemic issues in psychiatric care, particularly the barriers to timely treatment and the ethical dilemmas involved in involuntary interventions. It further examines the impact of anosognosia-lack of disease insight-on treatment, noting the difficulties in managing care for those unaware of their illness, and scrutinizes training materials from international organizations that might mislabel necessary psychiatric practices as human rights violations, thereby complicating the care landscape. The discussion extends to the legal and societal implications of psychiatric interventions, using Massachusetts' Rogers Guardianship as a case study to highlight the consequences of legalistic approaches to mental health treatment.

The so-called "amyloid cascade hypothesis" provides an elegant explanation of Alzheimer's disease (AD), has motivated the amyloid-lowering therapeutic strategy, and led to the elaboration of a rich experimental and conceptual toolkit for the field to progress. But it might be incorrect. The scientific evidence base supporting the efficacy and safety of current anti-amyloid antibody treatments in AD is weak.

Background: The Chinese educational sector is dynamic; hence, there is a need to anchor the factors that influence faculty job satisfaction and performance. These are channeled through organizational climate (OrgC) and employee happiness (EmH). The growing integration of artificial intelligence applications (AIAs)-like ChatGPT-into the learning environment raises questions about AIAs' moderating role in the relationship between EmH at work and EJoS.

Background: The advertising of unhealthy products, including unhealthy foods, drugs with abuse potential, certain cosmetic products and services, and tobacco, has raised significant public health concerns due to its role in increasing consumption and contributing to the rise of non-communicable diseases. Policy development and enforcement in this area necessitate an in-depth analysis of the relevant stakeholders. This study aims to examine the stakeholders involved in regulating the advertisement of unhealthy products in Iran, providing critical evidence for shaping advertising regulations and reducing the societal consumption of such products.
