Demonstration of active neutron interrogation of special nuclear materials using a high-intensity short-pulse-laser-driven neutron source.

Detecting shielded special nuclear material, such as nuclear explosives, is a difficult challenge pursued by non-proliferation, anti-terrorism, and nuclear security programs worldwide. Interrogation with intense fast-neutron pulses is a promising method to characterize concealed nuclear material rapidly but is limited by suitable source availability and proven instrumentation. In this study we have pioneered a demonstration of such an interrogation method using a high-intensity, short-pulse, laser-driven neutron source that offers potential benefits compared to conventional neutron sources.

Ventilation and features of the lung environment dynamically alter modeled intrapulmonary aerosol exposure from inhaled electronic cigarettes.

Electronic cigarettes (e-cigs) fundamentally differ from tobacco cigarettes in their generation of liquid-based aerosols. Investigating how e-cig aerosols behave when inhaled into the dynamic environment of the lung is important for understanding vaping-related exposure and toxicity. A ventilated artificial lung model was developed to replicate the ventilatory and environmental features of the human lung and study their impact on the characteristics of inhaled e-cig aerosols from simulated vaping scenarios.

Building happier bonds: gratitude as a mediator between dyadic coping and relationship satisfaction in romantic couples.

Introduction: Gratitude has been found to be relevant for relational well-being, and there has been ongoing interest in uncovering the mechanisms by which gratitude functions in interpersonal relationships. Only recently, gratitude has been studied within the context of dyadic coping-the interpersonal process of how partners communicate their stress, support each other during stressful times, and jointly cope with stress-in romantic couples. Drawing up on theoretical models on the functions of gratitude within close relationships and previous research, we aimed to advance this line of research and examined the potential mediating role of gratitude between dyadic coping and relationship satisfaction applying a dyadic perspective.
