Long-time behaviour of sphalerons in ϕ 4 models with a false vacuum

Abstract Evolution of sphalerons in a class of quartic Klein–Gordon models are studied under a growing perturbation. Sphalerons are unstable lump-like solutions that arise from a saddle point between true and false vacua in the energy functional. Numerical simulations are present...

Applying the commercial determinants of health framework to understand how digital platforms influence child and youth wellbeing

The influence of social media on youth mental health has been under debate in scientific communities over the last several years. In this perspective paper, we suggest that there is a need to shift focus away from finding ways to ascertain causal connections at the global scale t...

Nonlinear OrderSeparation in Two-Dimensional ElectronicSpectroscopy Quantifies Properties of Higher-Excited States

Abstract Two-dimensional (2D) spectroscopy combines high temporal and spectral resolution, allowing the observation of ultrafast energy transfer and the separation of homogeneous and inhomogeneous broadening. Typically, 2D spectroscopy is dominated by the lowest-order nonlinear s...

Understanding funding-related bias in gambling research: insights from unhealthy commodities industries and medical/pharmaceutical research – a scoping review

Despite the risk of funding-related bias (RoFRB) introduced by industry funding in gambling research, empirical investigations remain limited. To inform understanding of RoFRB in gambling research, this scoping review synthesized 52 peer-reviewed studies (2019–2024) spanning gamb...

Material imaginaries of the new iron curtain

The “social imaginary” has been critiqued for its overly deterministic qualities and resemblance to concepts of culture. Our article interrogates the materiality of the indeterminate at a time of heightened global uncertainty. Furthering a rapid response, material methodology in...

Experimental investigation of cross-laminated timber panels subjected to near-field blast loads

Research on the performance of structural timber elements subjected to near-field blast loads is lacking, with no known comprehensive experimental studies available to inform design standards and hazard mitigation strategies. This paper presents the results of an experimental tes...

ASector-Coupling Model to Evaluate the Role of Hydrogenin Low-Carbon Trucking

Abstract The global energy system must deeply decarbonize as soon as possible to avert the worst consequences of climate change, including the transportation sector, which accounts for 23% of global emissions. Several technological options have been proposed to decarbonize diesel...

The value of electronic tagging and tracking studies for understanding fish–hypoxia interactions

Abstract Objective Hypoxia (i.e., low dissolved oxygen availability) is a natural phenomenon but can also be induced by human activities (e.g., nutrient enrichment from runoff). Given that dissolved oxygen is essential for aquatic life, periods of hypoxia tend to have negative co...

“Oh my gosh, you’re too young to be sick!”: Unpacking the consequences of workplace mistreatment for young adults with disabilities.

Despite comprising a significant percentage of the workforce and being susceptible to mistreatment, young adults with disabilities have not been widely focused on in the workplace mistreatment literature. In this study, we take an intersectional approach as we examine the specifi...

65 TOPS optoelectronic multi-core computing unlocking multi-feature fusion enhancement

The rapid progress of artificial intelligence demands scalable, energy-efficient hardware with massive parallelism and high throughput. Although optical computing offers a promising post-Moore solution, current implementations face speed limitations and multi-core integration cha...
