Helping the waiter to hold his tray: Rigid haptic linkage promotes inter-personal motor coordination.

When a glass is lifted from a tray, there is a challenge for the waiter. He must quickly compensate for the reduction in the weight of the tray to keep it balanced. This compensation is easily achieved if the waiter lifts the glass himself.

In 2012, the New York City Board of Health prohibited restaurants from selling sugary drinks in containers that would hold more than 16 oz. Although a state court ruled that the Board of Health did not have the authority to implement such a policy, it remains a legally viable option for governments and a voluntary option for restaurants. However, there is very limited empirical data on how such a policy might affect the purchasing and consumption of sugary drinks.

Cardio-thoracic Centre, Thomas Drive, Liverpool L14 3PE, UK.
Background: The different levels of deoxyhemoglobin in the ischemic myocardium, induced by stressors such as dipyridamole, can be detected by blood oxygen level-dependent (BOLD) MRI and may be used to diagnose myocardial ischemia. The aim of this study was to assess the signal change in the myocardium on BOLD MRI as well as wall thickening between rest and dipyridamole stress images in ischemic and non-ischemic myocardium as identified on SPECT imaging.
Methods: Twelve patients with stress-induced myocardial ischemia on SPECT underwent rest and dipyridamole stress MRI using a double breath-hold, T2()-weighted, ECG-gated sequence to produce BOLD contrast images as well as cine-MRI for wall thickening assessment in 10 of the 12 patients.
Blood oxygen level dependent (BOLD) MRI: A novel technique for the detection of myocardial ischemia.
Eur J Intern Med
December 2006
Cardiology Department, Cardiothoracic Centre, Liverpool, UK.
Background: Blood oxygen level dependent (BOLD) T2* MRI detects signal variance within the myocardium based on changes in the deoxyhaemoglobin level following pharmacological stress, and it has the potential to identify areas of myocardial ischemia. The aim of the present study was to assess the utility of BOLD T2* MRI in the detection of myocardial ischemia in patients with an existing diagnosis of coronary artery disease.
Method: Twenty-one patients with established three-vessel coronary artery disease on coronary angiography underwent rest and dipyridamole stress MRI using a double breath-hold T2* weighted ECG gated sequence.
