When Social Media Ideals Backfire: How Idealized Digital Standards Undermine Self-Efficacy and Goal Attainability
The trouble is not that we aim too high and miss, but that we aim too high and stop believing we can get there.—Jennifer, Fitness Influencer Follower. (Study 1) 1 Introduction People often pursue long-term goals that promise enduring benefits, such as improving health, increasing fitness, acquiring new skills, or saving money.

Inequalities witnessing coherence, nonlocality, and contextuality
Abstract Quantum coherence, nonlocality, and contextuality are key resources for quantum advantage in metrology, communication, and computation. We introduce a graph-based approach to derive classicality inequalities that bound local, noncontextual, and coherence-free models, offering a unified description of these seemingly disparate quantum resources.
Simple proof that anomalous weak values require coherence
The quantum mechanical weak value Aw=〈ϕ|A|ψ〉/〈ϕ|ψ〉 of an observable A is a measurable quantity associated with an observable A and pre- and postselected states |ψ〉,|ϕ〉. Much has been discussed about the meaning and metrological uses of anomalous weak values, lying outside of the range of eigenvalues of A. We present a simple proof that anomalous weak values require that the (possibly mixed) pre- and postselection states have coherence in the eigenbasis of A.
Petrobras Strategy Targets Inspection Gaps in Piggable, Unpiggable Subsea Pipelines
(P&GJ) — Subsea pipelines are a cornerstone of offshore infrastructure, representing the most cost-effective and reliable method for transporting oil and gas across extensive distances [1]. In Brazil, offshore operations account for 96% of the country’s total oil and gas production, with 3,672 miles (5,909 km) of subsea pipelines spread throughout its territorial waters [2].
