Background: Young people often face barriers to psychiatric care and are increasingly seeking crisis services for mental health issues through the emergency department (ED). Urgent psychiatric care models provide youth in crisis with rapid access to time-limited mental health care on an outpatient basis. This scoping review aims to evaluate the impact of such urgent psychiatric services for youth aged 13-25 on patient and health system outcomes.

Diffusion broadening of spectral lines is the main limitation to frequency resolution in non-polarized liquid state nano-NMR. This problem arises from the limited amount of information that can be extracted from the signal before losing coherence. For liquid state NMR as with most generic sensing experiments, the signal is thought to decay exponentially, severely limiting resolution.

The growing field of nano nuclear magnetic resonance (nano-NMR) seeks to estimate spectra or discriminate between spectra of minuscule amounts of complex molecules. While this field holds great promise, nano-NMR experiments suffer from detrimental inherent noise. This strong noise masks to the weak signal and results in a very low signal-to-noise ratio.

The limits of frequency resolution in nano-NMR experiments have been discussed extensively in recent years. It is believed that there is a crucial difference between the ability to resolve a few frequencies and the precision of estimating a single one. Whereas the efficiency of single frequency estimation gradually increases with the square root of the number of measurements, the ability to resolve two frequencies is limited by the specific timescale of the signal and cannot be compensated for by extra measurements.

Engineering entanglement between quantum systems often involves coupling through a bosonic mediator, which should be disentangled from the systems at the operation's end. The quality of such an operation is generally limited by environmental and control noise. One of the prime techniques for suppressing noise is by dynamical decoupling, where one actively applies pulses at a rate that is faster than the typical time scale of the noise.

Cigarette smoking is very prevalent amongst patients suffering from mental disorders. In recent years additional scientific proof has been gathered regarding nicotine addiction mechanisms as effective treatments for smoking cessation. Some of these therapies are included in the "Basket of Health Services" of the State of Israel.
