Restart uncertainty relation for monitored quantum dynamics.

Proc Natl Acad Sci U S A

January 2025

Department of Physics, Institute of Nanotechnology and Advanced Materials, Bar-Ilan University, Ramat-Gan 52900, Israel.

We introduce a time-energy uncertainty relation within the context of restarts in monitored quantum dynamics. Previous studies have established that the mean recurrence time, which represents the time taken to return to the initial state, is quantized as an integer multiple of the sampling time, displaying pointwise discontinuous transitions at resonances. Our findings demonstrate that the natural utilization of the restart mechanism in laboratory experiments, driven by finite data collection time spans, leads to a broadening effect on the transitions of the mean recurrence time.

Article Synopsis
  • Subjective views on aging significantly influence overall well-being, but recent research highlights the role of these views within couple dynamics.
  • A new scale called Views of Couple Joint Aging (VoCJA) was developed to examine how couples perceive aging together, with a study involving 359 Israeli adults resulting in 14 key items reflecting Positive and Negative Views of Couple Joint Aging (PVoCJA and NVoCJA).
  • The findings reveal that higher PVoCJA is linked to greater relationship satisfaction, while higher NVoCJA correlates with more aging anxiety and lower relational satisfaction, indicating that views on aging as a couple can impact emotional and relational health independently.

The design of cathode/electrolyte interfaces in high-energy density Li-ion batteries is critical to protect the surface against undesirable oxygen release from the cathodes when batteries are charged to high voltage. However, the involvement of the engineered interface in the cationic and anionic redox reactions associated with (de-)lithiation is often ignored, mostly due to the difficulty to separate these processes from chemical/catalytic reactions at the cathode/electrolyte interface. Here, a new electron energy band diagrams concept is developed that includes the examination of the electrochemical- and ionization- potentials evolution upon batteries cycling.

Aim: The importance of parents' involvement in their child's medical care has been extensively discussed in the literature, and studies have indicated the need to expand the active role of parents in decision-making processes regarding such care. However, parents' actual wish to be active and informed in this context remains underexplored. The aim of the current study was to explore this gap by investigating the association between parents' shared decision-making (SDM) experience and their well-being during the course of their child's medical care, with a focus on parents' clinical decision-making style as a possible moderator.

Adult-child caregivers encounter various challenges due to their array of roles and tasks, often leading to a substantial sense of treatment burden. While previous research has explored factors contributing to treatment burden, much of it has centered on routine periods, leaving a gap in the understanding of this issue during crisis situations characterized by heightened stress and uncertainty. Therefore, this study aims to address this gap by investigating the mediating role of intolerance of uncertainty and war-related stress in the relationship between perceived social support and treatment burden among adult-child caregivers during the Israel-Hamas war.
