The ${{\rm Ho}^{3 +}}{:}{\rm YAG}$ pump laser source is capable of generating a pulse energy of 15 mJ from a single ${{\rm Ho}^{3 +}}{:}{\rm YAG}$ rod at room temperature at a pulse repetition frequency (PRF) of 700 Hz. A maximum power of 20.

While research has identified that victims are more likely to turn to informal versus formal sources, there is a lack of knowledge about what factors are predictive of help-seeking from formal sources. The current study explored the impact of incident and victim characteristics on help-seeking from formal sources among middle and high school TDV victims ( = 2,174).

Apathy, which is a behavioral executive dysfunction, frequently accompanies Alzheimer's disease (AD) and leads to higher daily functional loss. We assume that frontal lobe hypofunction in apathetic AD patients are more apparent than the AD patients without apathy.
