Broken bond-bending constraints and glass formation in the oxides.

Broken heart: Broken mind.

The increased frequency of sudden cardiac death after earthquakes and bombings has long proposed that emotional distress plays a role in acute coronary syndromes and arrhythmias. Since the 1960s, several controlled, prospective, epidemiological studies have reported emotional distress as a major risk factor for the onset and worsening of coronary heart disease (CHD) [1]. The Interheart study, a...

Realtime ultrasound guided percutaneous tracheostomy in emergency setting: the glass ceiling has been broken

Background In recent years ultrasound guided percutaneous tracheostomy (USPCT) has become a routine practice in critical care units. Its safety and superiority over conventional percutaneous tracheostomy and bronchoscopic guided PCT is proven to be non-inferior in elective cases. However its role in emergency percutaneous tracheostomy has never been studied, since percutaneous tracheostomy itse...

Broken Replica Symmetry Bounds in the Mean Field Spin Glass Model

By using a simple interpolation argument, in previous work we have proven the existence of the thermodynamic limit, for mean field disordered models, including the Sherrington-Kirkpatrick model, and the Derrida p-spin model. Here we extend this argument in order to compare the limiting free energy with the expression given by the Parisi Ansatz, and including full spontaneous replica symmetry br...
