Diffusive behavior for randomly kicked Newtonian particles in a spatially periodic medium
We prove a central limit theorem for the momentum distribution of a particle
undergoing an unbiased spatially periodic random forcing at exponentially
distributed times without friction. The start is a linear Boltzmann equation
for the phase space density, where the average energy of the particle grows
linearly in time. Rescaling time, the momentum converges to a Brownian motion,
and the position is its time-integral showing superdiffusive scaling with time
. The analysis has two parts: (1) to show that the particle spends
most of its time at high energy, where the spatial environment is practically
invisible; (2) to treat the low energy incursions where the motion is dominated
by the deterministic force, with potential drift but where symmetry arguments
cancel the ballistic behavior.Comment: 55 pages. Some typos corrected from previous versio

Values and their relationship with emotion processing and physical and psychological symptoms among Jewish and Arab breast cancer survivors
Introduction: Individuals from different cultures differ in their values, which encompass belief systems that individuals develop based on their culture, and play a pivotal role in shaping their perspectives. These values may affect emotion processing (EP): the recognition, interpretation, expression and response to bodily sensations, translated as emotions. These varying values may contribute to distinct emotional experiences, impacting physical and psychological symptoms in breast cancer (BC) survivors. Methods: This cross-sectional study investigated how EP including acceptance, expression (avoidance and approach coping), and awareness, may mediate the relationship between conservation values and symptoms of pain, fatigue, and depression among Arab (n = 62) and Jewish (n = 179) women BC survivors in Israel. Conservation values include tradition, conformity, and security. Results: Depression and fatigue were negatively correlated with acceptance of emotions, and positively correlated with avoidance and conservation levels. Emotion processing mediated the relationship between conservation and fatigue and depression. Arab women reported higher levels of various values, emotional acceptance, pain, fatigue, and depression symptoms compared to Jewish women. Conservation was higher in Arab women and correlated with both approach and avoidance coping which was not the case in Jewish women. Avoidance coping had a positive relationship with fatigue in the Jewish, but not the Arab women. Similarly, approach coping was negatively related to depression in Jewish, but not in Arab women. Discussion: Cultural differences are important for understanding the experience of cancer in individuals from different cultures. Future interventions for more conservative BC survivors should take culture into account.
